EDGE: A Stepping-stone Toward 3G Technologies in Pakistan

ABSTRACT

The business of wireless data is expected to grow in the region of 100-200 % per annum and the mobile communication industry agrees that wireless data services will form the foundation for future business. The enormous success of short messaging in many countries proves that people accept the benefits of non-voice services.

Enhanced Data Rate for Global Evolution (EDGE) is a technology that gives Global Systems for Mobile Communications (GSM) the capacity to handle services for the third generation of mobile telephony. It provides three times the data capacity of General packet Radio Service (GPRS). Using EDGE, operators can handle three times more subscribers than GPRS; triple their data rate per subscriber, or add extra capacity to their voice communications.

This article provides an overview of EDGE technology. In particular, starting from the introduction of this 2.5G technology I describe the core technical aspects and distinct features. I will provide a comparison with GPRS for data services and then a survey of the current state of this technology in Pakistan. I have also covered some benefits for operators and customers.

1. Introduction

The importance of wireless data and multimedia services both for business and end customers are increasing on an unparalleled scale. Enhanced Data Rates for GSM Evolution (EDGE) is a new radio interface solution and is based on an enhanced modulation. EDGE offers GSM network operators an evolution path to mobile data and multimedia services with a three fold increase of data throughput in the existing GSM spectrum. EDGE therefore provides an alternative for operators who do not have a Universal Mobile Telecommunication System (UMTS) license. Moreover it also represents a complement to UMTS for operators intending to first deploy UMTS only in densely populated areas, but who can also use EDGE to provide wide area coverage of future oriented 3G services. In the US market operators have chosen EDGE as the 3G solutions. [8].

We are presently experiencing the Wireless Application Protocol (WAP) as well as the higher   transmission  speeds of High Speed Circuit Switched Data (HSCSD), joined by the convenience of “always on-line” direct Internet connections with GPRS. [1]

EDGE, new radios interface technology with enhanced modulation, increases the HSCSD and GPRS data rates by up to three fold. EDGE modulation is going to increase the data throughput provided by the packet switched service even over 400 kbps per carrier. Similarly, the data rates of circuit switched data can be increased, or existing data rates can be achieved using fewer timeslots, saving capacity. Accordingly, these higher speed data services are referred to as EGPRS (Enhanced GPRS) and ECSD (Enhanced Circuit Switched Data).

EDGE, is a major improvement in GSM phase 2+. As a modification to existing GSM networks, EDGE does not require new network elements. [1]

In the US, for instance, EDGE is part of the IS-136 High Speed concept, which is one of the third generation Radio  Transmission  Technology (RTT) proposals from TR.45. EDGE is eventually going to be standardized which makes possible to achieve a global mobile radio system with many services characteristic to third generation systems.

2. Overview

The increased bit rates of EDGE put requirements on the GSM/GPRS network architecture. Figure. 1 illustrates the GSM/GPRS architecture, the shaded parts of which are discussed in this section. Other nodes and interfaces are not affected at all by EDGE introduction. An apparent bottleneck is the A-bis interface, which today supports up to 16 kb/s per traffic channel. With EDGE, the bit rate per traffic channel will approach 64 kb/s, which makes allocation of multiple A-bis slots to one traffic channel necessary. Alternative asynchronous transfer mode (ATM) or IP-based solutions to this problem can also be discusses.

One important fact is, however, that the 16 kb/s limit will be exceeded already by the introduction of two coding schemes (CS3 and CS4) in GPRS, which have a maximal bit rate per traffic channel of 22.8 kb/s. Consequently, the A-bis limitation problem is being solved outside the EDGE standardization, and it is therefore a GPRS related, not EDGE-related, modification. For GPRS-based packet data services, other nodes and interfaces are already capable of handling higher bit rates, and are thus not affected. For circuit-switched services, the A interface can handle 64 kb/s per user, which is not exceeded by EDGE circuit-switched bearers. [9]

2.1. Impact on GSM Network Planning

An important prerequisite, which to a large extent will determine the success of EDGE in GSM, is that a network operator be able to introduce EDGE gradually. For initial deployment, EDGE-capable transceivers will supplement standard GSM/GPRS transceivers in a subset of the existing cells where EDGE coverage is desired. Hence, an integrated mix of GSM, GPRS, and EDGE users will coexist in the same frequency band. To minimize effort and cost for the network operator, radio network planning (including cell planning, frequency setting of power and other cell parameters) must not require extensive modification.

2.1.1. Coverage Planning

One characteristic of non-transparent radio link protocols that include automatic repeat request (ARQ), is that low radio link quality only results in a lower bit rate for the user. Hence, low SIR for a user does not result in a dropped call, as for speech, but in a temporary decrease of user bit rate. For transparent bearers, which typically offer a constant bit rate, link quality control must be extended to incorporate resource allocation, in the sense that the number of dynamically allocated time slots fits the bit rate and bit error rate (BER) retirements. Transparent bearers, will thus be available in the entire GSM cell, but require fewer time slots in the center of the cell (where 8-PSK coding schemes can be used).

2.1.2. Frequency Planning

Most mature GSM networks of today have an average frequency reuse factor of around 9 (meaning that available frequencies are divided into nine frequency groups). However, there is also a trend toward tighter reuse factors. With the use of frequency hopping, multiple reuse patterns (MRP), and discontinuous  transmission  (DTX), reuse factors as low as 3 become feasible. EDGE supports a variety of reuse patterns. In fact, by its use of link quality control, EDGE can be introduced in an arbitrary frequency plan, and benefit from high SIR closer to the base stations. EDGE can be introduced in an existing GSM frequency plan, and that it also supports future high-capacity solutions based on tighter frequency reuse.

2.1.3. Radio Network Planning

An important prerequisite (and to a large extent, one that will determine the success of Edge) is that network operators should be able to introduce Edge gradually. The initial deployment of Edge-capable transceivers will supplement standard GSM transceivers in a subset of cells where Edge coverage is desired. An integrated mixture of circuit-switched, GPRS and Edge users will thus coexist in the same frequency band. To minimize operator efforts and costs, Edge-related implementation must not require extensive modification of the radio network plan (including cell planning, frequency planning, the setting of power levels and other cell parameters).

2.1.4. Channel Management

After Edge has been introduced, a cell will typically include two types of transceiver: standard GSM transceivers and Edge transceivers. Each physical channel (time slot) in the cell can be viewed as being one of at least four channel types:

1. GSM speech and GSM circuit-switched data (CSD);

2. GPRS packet data;

3. Circuit-switched data, enhanced circuits witched data (ECSD), and GSM speech;

4. Edge packet data (EGPRS), which allows a mix of GPRS and EGPRS users simultaneously.

While standard GSM transceivers only support channel types 1 and 2, Edge transceivers support all four channel types. Physical channels are dynamically defined according to terminal capabilities and needs in the cell. For example, if several speech users are active, the number of type-1 channels is increased, at the expense of GPRS and Edge channels. Obviously, channel management must be automated, to avoid the splitting of channels into static groups. Otherwise, trunking efficiency would diminish.

3. Interleaving

To increase the performance of the higher coding schemes in EGPRS (MCS7 to MCS9) even at low C/I, the interleaving procedure has been changed within the EGPRS standard. When frequency hopping is used, the radio environment is changing on a per-burst level. Because a radio block is interleaved and transmitted over four bursts for GPRS, each burst may experience a completely different interference environment. [7]

If just one of the four bursts is not properly received, the entire radio block will not be properly decoded and will have to be retransmitted. In the case of CS4 for GPRS, hardly any error protection is used at all. With EGPRS, the standard handles the higher coding scheme differently than GPRS to combat this problem. MCS7, MCS8 and MCS9 actually transmit two radio blocks over the four bursts, and the interleaving occurs over two bursts instead of four. This reduces the number of bursts that must be retransmitted should errors occur. The likelihood of receiving two consecutive error free bursts is higher than receiving four consecutive error free bursts. This means that the higher coding schemes

for EDGE have a better robustness with regard to frequency hopping.

4. EDGE & GPRS

EDGE, or the Enhanced Data Rate for Global Evolution, is the new mantra in the Global Internet Connectivity scene. EDGE is the new name for GSM 384. The technology was named GSM 384 because of the fact that it provided Data  Transmission  at a rate of 384 Kbps. It consists of the 8 pattern time slot, and the speed could be achieved when all the 8 time slots were used. The idea behind EDGE is to obtain even higher data rates on the current 200 KHz GSM carrier, by changing the type of the modulation used.

Now, this is the most striking feature. EDGE, as being once a GSM technology, works on the existing GSM or the TDMA carriers, and enables them to many of the 3G services. Although EDGE will have a little technical impact, since its fully based on GSM or the TDMA carriers, but it might just get an EDGE over the up coming technologies, and of course, the GPRS. With EDGE, the operators and service providers can offer more wireless data application, including wireless multimedia, e-mail (Web Based), Web Infotainment, and above all, the technology of Video Conferencing.

Now all these technologies that were named earlier, were the clauses of the IMT-UMTS 3G Package. But, with EDGE, we can get all these 3G services on our existing GSM phones, which might just prove to be a boon to the user.

The current scenario clearly states that EDGE will definitely score higher than GPRS. The former allows its users to increase the data speed and throughput capacity, to around 3-4 times higher than GPRS.

Secondly, it allows the existing GSM or the TDMA carriers to give the sophisticated 3G services. And with 1600 Million subscribers of GSM in over 170 countries, offer the full Global Roaming, anywhere between India to Japan and to San Francisco. Based on an 8 PSK modulation, it allows higher bit rate across the air Interface. There is one symbol for every 3 bits. Thus, EDGE Rate is equal to 3x GPRS Rate.

5. Future Evolution Towards WCDMA

The next evolutionary step for the GSM/EDGE cellular system includes enhancements of service provisioning for the packet-switched domain with the service provisioning in UMTS/UTRAN (UMTS terrestrial radio access network). GERAN will provide improved support for all quality of service (QoS) classes defined for UMTS: interactive, background, streaming and conversational. By doing so, a new range of applications, including IP multimedia applications, will be adequately supported. This part of the GSM/EDGE evolution focuses on support for the conversational and streaming service classes, because adequate support for interactive and background services already exists. Additionally, parallel simultaneous bearers will support multimedia applications with different QoS characteristics towards the same MS, such as multiple media streams handled through IMS domain. A driver for such evolution on the packet-switched side is the paradigm shift within the telecommunications world from circuit to packet-switched communications.

Both the core network defined for GPRS and the current GSM/EDGE radio access network require modifications to support enhanced packet services. The GPRS/EGPRS networks can quickly and cost effectively evolve with market needs, and align with services provided by WCDMA networks. The current evolution of GSM/EDGE, which covers all of the above aspects, is being standardized in 3GPP TSG GERAN. [4]

6. EDGE in Pakistan

Pakistan has the sixth largest population in the world – approximately 150 million. There are currently four mobile operators in the country. Mobile penetration at the end of 2003 was just 2.3% with a subscriber base of 3.4 million, while fixed line penetration was approximately 2.4%. Many geographic areas in Pakistan are without telephone coverage. To accompany recent positive economic development in Pakistan and the inherently low mobile penetration, high growth within the mobile segment is expected. At the moment the people in Pakistan are more concern with the text-enabled facility like SMS. Although the introduction of GPRS gave a new concept and new boost in Cellular network but still, people are not that much concern using Internet by their terminal. Few think that it still more costly and few believe that GPRS didn’t develop the interest for using Internet if we compared it by computer.

In April 2004 Norwegian mobile telecom operator, Telenor, bid for and ultimately won a license to operate a cellular network in Pakistan. The license covers the operation of Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS) and Enhanced Data Rates for Global Evolution (EDGE) technology for the network. [14]

Telenor Pakistan has signed two deals with mobile infrastructure contractors for different areas of the network:

Nokia have signed a three-year deal to build and operate a GSM / GPRS / EDGE network to cover the central and Northern Punjab region (phase one), centered around Lahore.

Siemens have signed a deal to build a GSM / GPRS / EDGE network to cover the southern areas of Pakistan, centered around Islamabad.

Further enhancements in data capability over the core GPRS / GSM network will be provided in both networks with the installation of Enhanced Data for Global (GSM) Evolution technology. This component of the two systems will be installed after the initial roll-outs and will allow the subscribers to have the use of advanced mobile services such as downloading video and music clips, full multimedia messaging, high-speed color Internet access and email on the move.

Nortel Networks will upgrade Ufone’s existing wireless systems and supply new GSM/GPRS core network and radio access equipment, including Mobile Switching Center, Home Location Register (HLR) and advanced Base Transceiver Stations (BTS).

A key component of the Ufone expansion will be Nortel Networks BTS 12000, designed to deliver additional capacity within a GSM/GPRS network while positioning operators to drive lower costs and to offer advanced wireless services based on third generation (3G) EDGE (Enhanced Data for GSM Evolution) technology. The expansion will also include Nortel Networks Passport Packet Voice Gateway (PVG) for migration of TDM voice trunking to a packet-based infrastructure.

7. Benefits

As highlighted previously the need to reduce business risk and make the best use of existing resources is of paramount importance within today’s business environment.

7.1. Financial

GSM based networks have become the standard within the cellular landscape. As EDGE is a GSM based technology and provides an enhancement for GPRS at a little additional cost it is considered the best way in which to capitalize on existing resources. [1]

7.1.1. Radio Access Network

In most cases GPRS enabled base stations and BSC’s can be simply upgraded to EDGE by way of relatively low-cost software and hardware upgrades, which will pro-long the life cycle of the deployed RAN elements.

7.1.2. Core Network

For GPRS enhancement, there is very little modification to be completed within a GPRS enabled core network, thus enhancing the sunk core network investment.

7.1.3. Antenna Sites

There is no requirement for additional antenna sites when deploying EDGE. Assuming high quality linear amplifiers with high RF output power are used within the BTS, the coverage pattern will be the same as the existing GPRS deployment, so protecting existing site investment.

7.1.4. Spectrum Utilization

EDGE triples the GPRS data capacity whilst using the existing GSM spectrum and offers up to three times the GPRS data rate to the end user. EDGE is spectrally the most efficient radio technology for data applications requiring up to 100Kb/s throughput (compared to CDMA and WCDMA), and only WCDMA is spectrally better for higher throughputs.

7.1.5. Applications

GPRS enabled applications and services will generally not require any additional investment to become EDGE compatible. This is also valid for known WCDMA applications.

Although the financial benefits of EDGE can be apportioned to individual network elements as outlined above, one of the main business drivers is that EDGE forms an essential part of the overall GSM evolution towards a seamless multi-radio GSM/ GPRS/EDGE/WCDMA network. As mentioned previously GSM is the main standard for cellular communications worldwide and the business benefits of deploying an industry standard technology can be seen in nearly every aspect of a network deployment, from end-user devices, to applications to hardware.

7.2. For Operator

Operators can also experiences the advantages of EDGE in following ways.

7.2.1. Migration to wireless multimedia services

The operator can increase data revenues by offering attractive new types applications to end-users.

7.2.2. Improved customer satisfaction

Increased data capacity and higher data throughput will decrease response times for all data services, thus keeping end users satisfied and connected.

7.2.3. Early deployment of 3G type applications

EDGE networks are expected to emerge in year 2001, when mature markets are likely to start demanding multimedia applications.

7.2.4. Quick network implementation

EDGE will not require new network elements and EDGE capability can be introduced gradually to the network.

7.3. For User

7.3.1. Improved quality of service

Increased data capacity and higher data throughput will eventually satisfy the customers’ need for QoS.

7.3.2. Personal multimedia services

Attractive new types of applications and terminals will become available.

7.3.3. Potentially lower price per bit

Lower cost of data capacity for high-speed data applications gives the operator flexibility in pricing.

8. Conclusion

While the tug of war between access technologies – CDMA vs. UMTS vs. GSM — continues to be debated globally, EDGE provides an ideal solution for GSM carriers to add data capacity using limited spectrum. Keeping in view the fact that GSM supports more subscribers today than any other access technology (roughly 65 to 70% of the global subscriber market), and that GSM/GPRS operators are scrambling to add capacity to support user growth and launch next generation data services, the increased capacity and throughput offered by EDGE becomes very compelling. And, in a market where wireless carriers must squeeze the most out of capital outlays–past and future, it is no real surprise that we are going to see a renewed wave of interest in EDGE from our GSM customers.

Today the position of EDGE as a technology evolution of GSM is clear. Initially promoted as an alternative to WCDMA and generally a niche technology, EDGE is now regarded as a key enabler for GSM/EDGE and WCDMA operators alike. Being able to drive business value from existing GSM infrastructure and spectrum is one of the main advantages, and along-with the ability of EDGE to reduce CAPEX, time-to-market and time-to-revenue, with regards the delivery of global high-speed data services, EDGE is a must technology.

The cellular companies working in Pakistan did not have the license for the EDGE. Now as the introduction of some new companies like Telenor and WARID, it is possible that in near future Pakistan will also be able to use this facility. Then GPRS can become a real important factor in cellular network, as the people in Pakistan will use the Internet not only for downloading ring tones but also can enjoy the streaming videos by their cell phone and so many other facilities.

How To Get Out Of A Low Sex Situation

The daily challenges in life, financial pressures, our jobs, taking care of kids, coping with aging parents and the like can take a toll on our desire for sex. This combines with the lack of sexual inventiveness can get us stuck in a sex rut which can hurt our desire. This can work in a vicious circle – low sex frequency leads to decreased sex drive and the depleted sex drive weakens the desire for sex.

How to get out of this situation so that you can have great sex again? Here are the 7 tips to help you to recover your sexual libido.

(1) Thinking about sex

If you hope to increase our interest in sex we have to take some time to flood our minds with sexual thoughts. This involves reliving those great sexual experiences you have with your spouse or to think of some new ways you can try to spice things up. You can also read some great articles or how-to help books or watch some informative videos, which can educate and allow you to know what is needed to improve sex life. The point here is to stimulate your mind in ways to get you into the mood.

(2) Increase your sexual attractiveness through dressing

The way you dress up yourself can play a great part in stoking those feel-good hormones, which can in turn influence your feeling of sexiness. How you look can influence how you feel. A changed outfit, a new fragrance, a makeover or a new hairdo can help to transmit the feeling that you are sexy and desirable. Even though you have grown accustomed to living with your spouse, this should not stop you from injecting some elements of surprise into the relationship, including the way you look.

(3) Communicating with partner

Sharing sexy words can be a great way for a sex-starved couple to reconnect and feel more inclined for romance. These words can be flowery, poetic and romantic like an old love letter or they can be spicy or graphic like a heated novel.

(4) Keep fit

Regular physical activity can boost the feel-good endorphins and can also improve your body image, promote blood flow to the sexual organs, making you feel sexier and giving your libido a healthy boost. In addition, Kegel exercises (done to tighten the pelvic muscles) can work to enhance sexual sensations and help boost desire.

(5) Spending time with each other

Just you and your partner only, separate from kids and work, during which serious topics such as kids and work are not discussed. You can plan a weekly date such as going out for dinner or a walk; but not to the movies or other activities that may not be conducive to talking to each other. If you cannot afford a babysitter, go out on the porch and have a glass of wine together after the kids go to sleep. You can also find some interesting and exciting things to do together such as going for tours, enrolling for some dancing or yoga classes.

(6) Allot some time to do something you enjoy

You can take time for yourself everyday even if this is only 10-15 minutes per day. This can help you to reduce stress and give you more energy for your partner. The more connected to who you are, the less you get lost in the daily grind, which pulls you away from your partner. The more sensual and the more connected you are to yourself, the more available you are for your partner.

(7) Just do it

If you have not had sex for a while, it is likely that your sexual desire will decrease gradually. The best way to overcome this is to have sex even when you are not in the mood at times. If you try to wait for the mood to come, chances are that you will never have sex again. Research has shown that the more we have sex, the more sex we want to have. Connecting sexually promotes the secretion of the attachment hormone, oxytocin, which can increase libido.

Japan’s Big Three’s Models Named Best Deals

Car buyers are always in the lookout for the car offering the best value for their money. Different firms have been guiding prospective car buyers on how to choose the vehicle the suits their needs best. From performance to fuel economy to safety, all bases should be covered in choosing a vehicle.

IntelliChoice, one of the leading sources of pertinent information to car buyers, recently announced their “Best Deals” list. The list contains what the online outfit thinks is the best vehicle in different classes. For the month of April, IntelliChoice announced their “Best Deals” and this has been done coinciding with the ongoing New York International Auto Show (NYIAS) in the Big Apple.

This month’s list includes several models from Japan’s three biggest car manufacturers. These vehicles are seen as the measuring stick for future production vehicles unveiled and showcased at the New York Auto Show. James Bell, the publisher of IntelliChoice.com, has this to say with regards to the list and the vehicles showcased at the event: “Even more than recent auto shows, the New York show offered a look at some very compelling future competition to many of the mainstays on our monthly ‘Best Deals’ list.”

The Honda Civic hybrid is rated as the best deal for the Compact Car over $16,000 class by IntelliChoice.com. For the Compact Car under $16,000 class, the best deal is touted to be the Honda Civic DX with an automatic transmission.

Aside from these two models, another Honda produced vehicle was named as a best deal in its class – the Honda Civic Si. The said model is named as the best deal in the Base Sport Car class. The Honda Odyssey is once again named as the best deal for the Minivan class. The Honda Odyssey has been dominating that class in recent history but will face strong competition in the form of the Ford Flex recently unveiled at the New York International Auto Show.

A Nissan model is also named as one of the best deals for the month of April. The Nissan Frontier King Cab XE 2WD with a manual transmission is named as the best deal for the Compact Pickup Truck 2WD class. The King Cab is the first crew cab body style compact pickup truck in North America and since its inception in the U.S. auto market has been popular among car buyers. With its trademark dependability, the Nissan Frontier is not a surprise choice as the best deal for its class. Its high performance construction and components such as the Nissan spark plug wires are one of the reasons why the Frontier sits at the top of its class.

Toyota, the surging Japanese car manufacturer, also landed several of its models at the “Best Deals” list. The popular Toyota Prius is named as the best deal for the Midsize Car under $21,000 while the Prius Touring is named as the best deal for the Midsize Car over $21,000 class.

For the Large Car class, IntelliChoice picked the Toyota Avalon Touring as the best deal for consumers. The Toyota Highlander Hybrid with a third row seating and 2WD configuration is named as the best deal for the Midsize Crossover class. The Toyota Matrix Standard with manual transmission is also named as the best deal for the Small Wagon class.

For the Compact Pickup Truck 4WD class, IntelliChoice picked the Toyota Tacoma Regular Cab 4WD as the best deal. The Toyota Tundra Regular Cab V6 2WD Short Bed is named as the best deal for the Full-Size Pickup Truck 2WD 1/2 Ton class.

The Search for the Best Treatment for Common Cold Symptoms

Opinions vary about the best treatment for common cold symptoms. Zinc common cold remedies are much in the news, but some controversy surrounds their use.

Over the counter products, vitamin supplements and herbal remedies are really the only options a person has for treating a cold. Because colds are caused by viruses, there are no effective prescription medications and a visit to the doctor is usually unnecessary, unless a secondary bacterial infection, such as a sinus or ear infection occurs. Antibiotics are not effective for either preventing or treating a cold. Over-use of antibiotics has led to the development of more resistant strains of bacteria.

According to many experts, the best treatment for common cold symptoms is to get plenty of rest and drink lots of fluids. Probably, because so many people have a busy lifestyle, pharmaceutical companies keep coming up with products like zinc common cold remedies and other multi-symptom cold relievers. Advertising for these products typically suggests that these can help you “get on with your life”. But many of these products have unwanted side effects. Some can be relatively serious, considering that cold symptoms are typically gone in a week or so.

Some people who have used a zinc common cold nasal spray or gel have lost their sense of smell. One company was sued and settled out of court without admitting fault. At least two different clinical studies have confirmed that these zinc common cold remedies effectively reduce the duration of symptoms, but other studies confirm that these preparations can cause a permanent loss of the sense of smell. In fact, one study performed by the George Eby Research Group in Austin, Texas concludes that “it is unethical to introduce any potentially permanent anosmia-inducing agent such as zinc or other heavy metals into the interior of the nose in a manner that could result in contact with the olfactory region to treat a temporary discomfort such as a common cold or allergy.” The term anosmia means loss of sense of smell.

Several other studies confirm that when zinc common cold remedies come into contact with the lining of the nose, permanent loss of the sense of smell can occur. Manufactures of these products claim that they may be the best treatment for common cold available and can reduce the duration of cold symptoms to as little as two days. But, in fact, many people recover from a common cold in a couple of days, anyway. Some viral infections last longer in some people and symptoms may last as long as two weeks, but the study in Texas showed that the zinc common cold remedies did not significantly reduce the duration of common cold symptoms. The majority of volunteers had recovered within a week, whether they were given the zinc common cold remedies or a placebo.

Because some people recover from symptoms so quickly, without treatment, it has been difficult for researchers to determine the best treatment for common cold symptoms. Some people are more susceptible to infection with cold viruses than others. A recent study indicates that asthma sufferers, who typically have more than their fair share of colds, produce less anti-viral proteins than normal. Supporting the belief that efforts to improve immune system function can be the best treatment for common cold symptoms, as well as the best prevention.

Vitamin C supplementation is considered, by some, to be the best treatment for common cold symptoms, but opinions vary. Some studies have shown that it is an effective preventative; others have shown it to be less effective. Again the difference in the results of these studies is probably related to the difference in people. Injecting the rhinovirus directly into the nose causes an infection in 95% of people, but only 75% of them develop any symptoms at all. If you decide to increase your vitamin C intake and you develop diarrhea, then you are getting too much vitamin C and should reduce the daily dosage.

Many herbalists still recommend Echinacea as the best treatment for common cold symptoms. Some still recommend it as a preventative, but clinical studies have shown that taking the herb for extended periods of time can be toxic to the liver. It was used traditionally by Native Americans as a treatment, not a preventative. For occasional use Echinacea appears to be safe, but there are safer herbs.

Andrographis paniculata, an herb used in traditional Asian medicine, may be the best treatment for common cold symptoms and an effective preventative. In one study, a group of volunteers were given the herb or a placebo and results showed that those who were given the herb were less likely to become infected with influenza viruses; these are some of the viruses that can cause common cold symptoms. In those people who took the herb and did develop the flu, symptoms were less severe and complications, such as pneumonia, did not develop. Andrographis paniculata has been shown to have no toxic effects on animals, even when used in large amounts.

The complications that are associated with zinc common cold nasal sprays or gels are not associated with dietary supplements of zinc. And, zinc is important to proper immune system function and overall good health.

The Opposition of Emotionally Colored and Emotionally Neutral Vocabulary

A tendency to judge that speech is only an instrument for making statements is rather primitive. Some people forget that there are a lot of different possibilities. The way we speak also expresses our emotions, attitude to people interrelations between the audience and the speaker.

Sometimes it is necessary to guide people, to warn them or to show somebody’s disapproval or approval or to make your speech sound more enthusiastic or encouraging. We should take all these into consideration while investigating the lexical meaning of words. Using such terms as “emotive” or “expressive”; “affective” or “evaluative”, some people think they are synonyms, for example, that an emotive word is of necessity also a stylistically colored word, or considering all stylistically colored words as emotional. But that is not the case.

So, let us agree that so-called emotive speech is any utterance expressing different human emotions. It is easy to find in speech a great number of syntactical, lexical and intonational peculiarities. Thus, by lexical peculiarities I mean special, emotionally colored words. The emotional coloring of the word may be occasional or permanent. Let us focus on the second. Lexical units acquire their emotional coloring, in other words, their affective connotation, in emotional contexts of particular situations.

The most common type of emotional words, as it seems to me, are interjections. The fact is that they express a lot of emotions without naming them: Ouch! My! Boy! Heaven! Wow! Ah! etc. The interjections may be derived from other parts of speech or be primary interjections. For example, if you describe something as a “drag”, what do you mean? It is boring, too difficult or physically exhausting? Certainly, something that is annoying or boring. We can find a lot of emotional words in everyday small talks or in the literature: ” I love Sibyl Vane. I want to place her on a pedestal of gold, and to see the world worship the woman who is mine. What is marriage? An irrevocable vow. You mock at it for that. Ah! don’t mock.” ( Oscar Wild “The Picture of Dorian Gray” Moscow Progress Publishers 1979 Volume One, page 170)

To express irritation, mockery or any other emotions the speech should possess some special traits, that would show the audience that the speaker’s emotions are very strong. The traditional word order is not used in such cases, but one can obviously find the inversion. More to that, very interesting and vivid examples of echo-conversations can be found in everyday spoken speech. Sometimes it sounds really amusing: “Why should I… ?” – “Stop why-should-I-ing!” or “Oh, come on!”- “Don’t come-on-me!” These are examples of mockery back-chat. It is funny to find brand new words like “why-should-I-ing” invented by the speaker in the moment of utter irritation. This type of emotional speech is definitely increasing in the speech of young people today, as the native speakers assume.

The emotionally colored words are opposed to the emotionally neutral ones. These words actually express notions (It is the so-called nominating function) but they fail to express the speaker’s emotions or his attitude towards people or the speaker’s mood. However, sometimes it is very difficult to tell the sets as they are not very distinguishing, there are a lot of mixed cases. Some of them may possess traits that belong to both. Many words are definitely neutral in their primary, direct meaning but absolutely emotional in the certain conversation under the conditions of the context.

Another group of words may be called “evaluator-words” which contrasts in speech to the neutral words. These words, while we use them in the sentences, can not only show the presence of emotions but identify or specify them.

Just to sum up what have been mentioned I would like to underline that emphatic and emotional words do not show emotions by themselves but impact these to the whole utterance in the combination with syntactic and intonational means.

Marine VHF Radio

Types of VHF sets:

Non-DSC sets

Non-DSC VHF sets on yachts and motorboats will still continue to work, will still be legal to use and certificate holders do not need to do a conversion course until they choose to upgrade. After 2005 Coastguards will cease to monitor Channel 16 in the way that they do now, that is with a dedicated officer on headset watch 24 hours a day, but they will continue to have a loudspeaker watch on channel 16 in the operations room. Increasingly the boat without VHF DSC radio will be at a disadvantage.

A transportable set is an invaluable second radio for use in an emergency when it can be taken into a life raft or used on deck to communicate in a rescue situation. It is useful for safety reasons in a tender when going ashore or in a safety boat when organising dinghy sailing events. A portable set is a good buy for non-boat owners who charter or who go afloat occasionally. They have a limited range but do require licensing and certification. Portable sets with a very limited DSC facility are available. They are intended as an addition to a full VHF DSC set, not as a substitute. Note that the portable set covered by a ship’s radio licence can only be used on the vessel covered by the licence or by its tender(s). It is illegal to use the portable ashore.

VHF DSC radio sets

From 2001 all new non-portable radios sold must be VHF-DSC or be capable of being converted to DSC by the addition of an extra ‘black box’. These are called DSC Controllers. It will provide the digital selective calling (DSC) facility which is the special feature of the new type of set. What this does is to send, on channel 70, a burst of digital signals in a code to ‘call up’ another DSC set. This call can be directed at an individual, using their MMSI, a group of boats or ‘all stations’ in an emergency. Once the link has been established by the digital ‘call’, normal voice   transmission  will be used. The DSC is essentially a new method of establishing communications, more reliably than was possible before. The digital signals are of high radio quality and rapid, the alert taking just 0.5 seconds. It can be used in both routine and distress situations.

There are different classes of controller with varying levels of capability for use in different types of vessel.

The Class D controller is the one designed for use with VHF on yachts and motorboats who make passages within VHF range of the coast. Fitting one of these is not compulsory on private boats. On small boats used at sea commercially, sea school boats for example, it may become a requirement. This will be to the great advantage of their students who will be able to see the sets in use and appreciate their advantages.

Other controllers for VHF DSC are available to meet the requirements of ships. These include Class A and B Controllers, which have enhanced capabilities.

What is the range of the set?

Those sailing across an ocean, or even the Bay of Biscay, need radios that transmit over vast distances. Licensing arrangements are different too.

The range of  transmission  of VHF radio telephones is limited by a number of factors. The height of the aerial is very significant as the propagation of the radio waves is only slightly more than ‘line of sight’. This includes the aerial height of both the transmitting and the receiving station.

When talking from yacht to yacht expect a range of 10 to l5 miles with aerials fitted at the tops of the masts. Those commonly fitted to yachts are known as ‘unity gain’ aerials. They are made of thin wire and often have wind instruments attached. They are recommended because, although the range is not as good as the taller rigid aerials used on motorboats, they cope better with the heeling effect often experienced on yachts! The better range of a ‘high gain’ motor cruiser aerial is only achieved if it is mounted vertically.

It should be possible to talk to a Coastguard station from 30 to 40 miles offshore because of the height of their aerial.

Transmitting range is also affected by the transmitting power of the set. The maximum power allowed is 25 watts. There is also a low power setting, which reduces the transmitting power to 1 watt. This should be used for all short range routine communications. You might think that it is always a good idea to broadcast your signal as far as possible. This it not so. Remember that each channel can only be used for one  transmission  at a time. Powerful signals cause more inference to other radio users. If you are calling another craft nearby or a marina, use low power. Try to use low power for all routine communications. The use of low power does not change the receiving range of the set.

A portable VHF set has yet another type of aerial. This is flexible and will operate at a wider range of angles. The low aerial height and a maximum power output of 5 watts reduces the range of  transmission  of these sets. Between portable radios the range can be up to 5 miles, increasing to 10 miles to a Coastguard station, if there is no land in the way! Remember, with portable radios there is always the risk that the battery will go flat.

The information about ranges of  transmissions  is for average conditions and good circumstances. Ranges can be influenced by:

o Atmospheric conditions, especially high pressure, can increase the range and cause interference from distant stations.

o Land. Boats operating near land may have poor reception with signals being blocked by hills or buildings.

o Incorrect installation of the aerial, or damage to the coaxial cable connecting the aerial to the set, can give poor reception.

o The proximity of other electronic equipment can cause interference.

For these reasons it is best to have the fitting done, or at least checked, by a professional electronics engineer.

A portable radio has a range of 5 miles to another portable, 10 miles to a Coastguard Station.

All distress calls should be transmitted on high power.

Many yachts carry emergency VHF aerials in case of dismasting, which is a very good idea, but failure of the electrical supply is a more frequent problem! The emergency aerial has a plug attached to connect it to the back of the set. For maximum range, situate the aerial as high as possible, but realistically expect a greatly reduced range. When the mast is lost, many people are surprised to hear the radio apparently still working. This is because the co-axial cable is acting as an aerial over a short range, but transmitting without an aerial will damage the set permanently.

A portable radio could be useful under these circumstances!

Everything You Need to Know About Investing

To become successful with your money, you have to make your money work for you. You sell your labor which in return makes you money. By making each individual dollar work for you, this in return makes you wealthy over time. There are a plethora of investing opportunities out there. The key is to figure out which one is the right one for your financial situation.

Stocks
The most popular of all investing opportunities, are stocks. Stocks are probably the main thing you think of when you hear of investing. When you buy a stock, you buy partial ownership of a company. Stocks range anywhere from $2, to $12,000, which can appeal to a large variety of people. To be successful when trading stocks, you have to buy low and sell high. Of course this isn’t easy, considering the market is always fluctuating. You need to watch the history of the company, know the PE Ratio, the day range, the 52 week range, etc. Knowing this information can help you predict if the stock will go up or down. You can make a lot of money investing in stocks, which means you can also lose a lot of money. You want to keep in mind that most investments in stocks are long term investments. It is very risky investing, but if you do the proper research of the history of the company, you can get a very good return.

Stock Investing Tips

1.) Have the Right Expectations
When you are investing in stocks, you want to make sure you aren’t expecting to become Warren Buffet over night. It just wont happen. You want to make sure you do the proper amount of research, and make sure you know the history of the market as well as the company you are investing in. When investing in stocks, the return is around 10%-13%. You don’t want to make hasty decisions and buy and sell a lot just because you aren’t making the money you expected. Make sure you know how long you are keeping an investment, and then make a commitment. This will help you focus on the principles.

2.) Don’t Listen to the Media
Don’t get caught up in what everyone is talking about and what is being said around you. It will take your decision from being based on research and history, to just “hear-say”. This will hurt your investments immensely. Most of the hype and other things that are being said are just the daily fluctuation of the market.

3.) Stay Focused
You want to make sure you are putting all your effort and focus into your investments. Once you buy a stock, you own part of a company. Make sure you treat it the way it is and make sure you do the proper research of all aspects of what you’re investing in. Doing your research can change your investment of making a profit of $15,000, to losing $15,000. In the end, it’s always worth it to do the extra work.

Mutual Funds
When you invest in Mutual Funds, you are pooling your money with a number of other investors. You then pay someone to professionally manage and choose each individual security for you. There are a variety of different mutual funds you can choose to invest in, which range to fit your investment strategy.
3 Types of Mutual Funds
1.) Open-Ended
2.) Unit Investment Trust
3.) Close-Ended

Mutual Fund Investing Tips

1.) Look at the Fees
Always look at the fees involved when investing in Mutual Funds. When you pay more for something, this usually means that you are going to be getting a better product or service, right? Yes! Makes sure you find the best deal, but make sure you are investing the right amount of money in the right places. It can change the course of the whole investment in the long run.

2.) Research the History
One thing you can do to prepare an investment is to check out the history of the Mutual Fund. Just like anything, the history shows how well it has performed, and can be a good indicator. This can directly tell you if it will be a good investment whether it be long term or short term. Another thing you want to look at, is the asset of the fund. If it’s doing good, and there is a community of people investing in it, it can tell you if its a smart idea to invest yourself. Always check the history of any investment before you decide to purchase.

3.) Look at the Contract
You never know what is all involved until you take a detailed look at the prospectus provided by the fund. You want to make sure you don’t just know bits and pieces of what’s involved, but everything there is to know, and then some. Make sure you know all the fees involved with buying and selling funds, and if there are international fees required. Knowing this can help you determine if the company is a solid company where you can make money, or if you are getting into something you will regret in the future.

Bank Investments
Bank accounts are one of the simplest form of investment. Most banks give you a very small percentage for opening a bank account and giving them your money. This percentage barely beats the rise of inflation, so unless you are keeping hundreds of thousands of dollars in the bank, you won’t be creating any wealth from this form of investment. Another way to invest in your bank is a CD, or Certificate of Deposit. A CD if very similar to a bank account, but they are usually for a fixed amount of time. They can be monthly, every six months, a year, etc. the CD is then held until its maturity date, and paid back with interest. A Certificate of Deposit usually earns more money than an account at which you can withdrawal the money at any time, like a bank account.

Alternative Investments
Apart from the basic investments, there are other special securities. These investments include gold/silver, real estate, etc. These investments are speculative and can be very high profit, however; you need to have the knowledge.

1.) Gold & Silver
The first thing you want to do before you invest in gold or silver, is to look at the market and decide if now is the best time to invest in precious metals. You can also talk to a professional and decide when the best time to buy and sell would be. You want to make sure you are familiar with the variety of ways to invest in silver. You can invest in silver mining companies, silver ETF’s, silver futures, silver bullion, and also silver coins. You want to make sure the Exchange Traded Funds (ETF) are backed by physical gold and silver. Another thing to remember, is to not just own a paper owning, but the actual precious metal as well.

Peeling Penis Skin – 7 Potential Causes

Dry, peeling penis skin can send any man into a state of panic, especially when there is no obvious cause. Flakes of skin falling away from the Johnson are not only unattractive, they can appear as a sign of poor health, not to mention causing serious discomfort.

Fortunately, in most cases, the underlying issue can be easily addressed. With the right treatment and a good understanding of proper penis care, the problem can be banished in a matter of days, leaving the skin soft, smooth and attractive.

Common causes of flaking, peeling penis skin

  • Friction. Dry masturbation or sex is a leading cause of peeling, stressed skin. Using a personal lubricant (one designed for the purpose) can reduce the occurrence of dryness and irritation of the penis.
  • Yeast infection. Candida yeast infections, also known as thrush, are one of the most common causes of peeling, itchy penis skin. Other symptoms of yeast infection include red bumps or sores, a burning sensation during urination, severe itching, and a whitish, lumpy discharge. Most yeast infections can be treated with topical anti-fungal creams. Although not considered a sexually transmitted infection, Candida is highly contagious and can easily be passed from one partner to another, so men who develop a yeast infection should encourage their partners to be treated, as well.
  • Balanitis. This condition refers to any inflammation of the glans – or head – of the penis. The inflammation may be related to yeast infection or poor hygiene. Keeping the area clean is essential, especially for men who are uncircumcised, and topical creams may be used to treat the pain, itching and flaking caused by the infection.
  • Phimosis. Men or boys who are unable to retract the foreskin may be diagnosed with phimosis. The tight foreskin may develop a dry appearance, especially if it is stretched during an erection or as a result of masturbation or sex. Phimosis can often be treated by gently pulling the foreskin back a little at a time; applying a high-quality moisturizer can be of assistance in this process. In some cases, doctors may recommend circumcision as the best solution.
  • Sexually transmitted infections. Certain communicable diseases can cause dry penis skin that flakes and peels. Men who are sexually active should be tested for STIs on a regular basis and follow through with any recommended treatment.
  • Dermatitis. A skin sensitivity to something in a man’s environment – from laundry detergent to fragrances to latex condoms or spermicides – can cause the skin to become irritated, itchy, and dry. Avoiding potential skin irritants can eliminate this problem, and using a soothing vitamin cream when irritation does occur can help to clear up any issues.
  • Psoriasis or eczema. Men who have psoriasis or eczema elsewhere on their bodies may also develop dry, scaly or red patches of skin on the penis. Vitamins A and E are often used as natural solutions for these issues; hydrocortisone creams are also frequently prescribed, but caution is advised in this case, as steroid creams can cause thinning of the delicate penile skin.

Any unusual penis symptoms are best tended to by a doctor who has experience in men’s issues, especially if the owner of the package is not sure what is causing the problem. In some cases, such as communicable diseases, prescription medications may be required to clear up the problem.

Dry penis skin should be allowed time to heal; abstaining from sex until the cause of the issue has been identified can prevent further damage and discomfort. In addition, applying a penis health creme (most health professionals recommend Man 1 Man Oil) containing penis-specific nutrients such as vitamins A and E can help to nourish the skin and speed the healing process. A good penis cream containing natural moisturizers such as Shea butter is ideal for even the most sensitive skin; applying the cream after a shower is best, as this allows for rapid absorption for maximum benefit.
