Types and Advantages of Storage Heaters

A storage heater is an electrical device which stores the thermal energy when base load electricity is available at lower cost generally at night times and releases this heat at day times when it is required. Heat is stored in the clay bricks or other ceramic material, of concrete walls, or of water containers.

Types:

Convector Storage Heaters:
These heaters have a convector heater in addition to a standard storage heater system. This storage heater is ideal for a living room that has higher occupancy.

Fan Assisted Storage Heaters:
A fan is incorporated in to the heater which takes air through the heater and discharges it through the vent at the base of the heater. These heaters are highly insulated and they are most efficient at storing heat. Fan storage heaters are ideal for home and office use. The fan can be controlled with a separate thermostat control, which is supplied with the storage heater.

Advantages of Storage Heaters:

• They take up less space when storage heater is incorporated into the building's floor plan.
• By turning of gas and otherhttp://www.blogger.com/img/blank.gif storage heaters as an economy measure the house can be made cold at the night times. But when night storage heater are on at night, the house is still warm at those times.
• The initial costs and the installation of these storage heaters is easy when compared to gas fired boilers, piping and radiators.
• Night storage heaters when compared to central heating systems requires low maintenance and operating costs.
• Using storage heaters allows houses to be sited in areas where natural gas distribution systems are not available with out forcing the home owners to pay high electrical bills.

The above are the details of various types of storage heaters and their benefits.

Effects of Methamphetamine, a Club Drug

Methamphetamine, is one among the harmful and dangerous club drugs. Compared to other drugs it is more addictive. A strong stimulant which is related to amphetamine, excites the central nervous system and makes it more addictive. The most common form are white, odorless, bitter in taste that easily dissolves in water. It can also be found in clear, large chunky crystals and small brightly colored tablets. It can be smoked, injected, snorted, or taken orally.

Effects of Methamphetamine: Physical effects of this drug include wakefulness, increased rates of heart and blood pressures. It also increases body temperature and rate of breathing. Long term usage of this drug results in insomnia and several dental problems. Users who particularly inject the drug may be effected by infectious diseases like HIV, AIDS and hepatitis.
Psychological effects include, feeling of euphoria, increased nervousness, irritation, mood disturbances, violent behavior, anxiety, confusion,and paranoia.

The dangers involved in using this drug are mainly due to addiction. This drug is highly addictive and leaves adverse effects when used for long term. Chronic abuse produces a mental psychosis characterized by paranoia, picking at the skin, preoccupation with ones own thoughts, hallucinations.

According to the research conducted by National survey on Drug use and Health, during 2009, 1.2 million aged 12 and above had abused Methamphetamine at least once in the year. The NIDA funded 2010 'Monitoring the Future' study showed that, 1.2% of the 8th graders, 1.6% of the 10th graders, 1.0% of the 12th graders had abused this drug at least once in a year.

This is how Methamphetamine is effecting the physical health and mental conditions of the individuals.

Know About the Psychological Effects of Club Drugs

Most of the cases suffering from some psychological problems are due to drug abuse. This reflects the severe effects of drugs on ones mental state. It is only for few moments that the drug addicts will feel happy and excited when they consume drugs. But the later stage is like hell for them. Again in order to get rid of the later affects they tend to have some more drugs which results in complete drug dependence and drug addiction. Each and every drug shows its adverse effects on the mental state of the abuser in a different way. If the drugs are taken in combination to alcohol or other harmful drugs the condition is even worst. Let us see the effects of different drugs.

Ecstasy- This drug can be injected, snored, smoked, or ingested. The intensity of mental effects are high in all the cases. The effects of this drug lasts from 45 minutes to 8 hours depending upon so many factors. Psychological effects may last up to weeks after drug use. They include confusion, depression, drug craving, anxiety and sleep problems.

Ketamine- This drug is in liquid form and can be taken by mixing with any liquids or can be added to smokable material. Higher doses of ketamine results in hallucination and other side effects include, lack of coordination, sense of vulnerability, aggressive and violent behavior, which finally results in tremendous psychological dependence.

Rohypnol- This drug is usually taken orally or the powdered form can be snorted. Because of its tasteless and odorless quality, it easily slips in to any drink. Higher doses can cause loss of consciousness, memory loss and dizziness.

The regular intake of these drugs leads to dependance and a stage of craving for things. Future effects of these drugs are highly dangerous which makes a person depressed, stressful and even raises the thoughts of committing suicides.

Optical Computing and Its Advantages

An optical computer is a device that performs digital computations with the use of photons of visible light or infrared beams instead of using electricity. Features of this optical computer includes it is fast, it can be easily manipulated and it is very well suited for parallelization. There are two approaches available for developing optical computers, one is to generate a completely new kind of computer, which can perform all functional operations in optical mode and the other approach is to build computers that have the same architecture as present day computers but uses optics.

Using light instead of electric current to build a computer brings lots of advantages and the following are the advantages of the optical computers:

Higher Performance:
Velocity of the light is higher when compared to the electricity used in the conventional computers and this property of the light makes the optical computer to perform high than the conventional computer. This is one of the most significant advantage of the optical computer.

Consumption is Less:
Computers of the present day consume a lot of energy, for instance, modern CPUs often need over 80 watts in idle state, around 120 watts in normal use and up to 250 watts in performance mode. Optical computers have the potential to be more power-saving than conventional ones.

Less Noise:
Due to rotating fans and drives lot of noise is caused by the conventional computers, whereas an optical computer could be almost noiseless, since probably no fan will be needed and the light sources can be cooled with passive coolers and heat pipes built out of aluminum or copper.

Less Heat is Released:
Lasers are used as the source of light in the optical computers which consist of a small spectrum of different wavelengths. Depending on the field of application lasers have different needs of energy and produce heat to a greater or lesser extent.

Less Wear:
Conventional computers uses moving parts such as fans, hard disk drives and conventional optical removable storage in which friction is produced, because of which the mechanical parts wear out. Break and optical computers do not need fans, as optical processor does not heat up.

High Parallelism:
Optical computers can be built with higher bandwidth and within one data path several data sets can be transmitted parallel at the same time using different wavelengths or polarizations. The higher parallelism and the superior velocity of light allow extreme processing speeds.

Due to all the above benefits, optical computing is being widely used.

Advantages of DBMS For A Business

Database management system is a computer program that controls the creation, maintenance, and the use of a database. The following are the advantages of implementing DBMS in an organization:

Flexibility:
As the data and the programs are interdependent and when there is addition or deletion of the database the programs do not have to be modified.

Fast Response:
All the data of the organization is integrated in to a single database. Complex requests can be handled much more rapidly and faster response improves customer satisfaction.

Multiple Access:
Database software allows data to be accessed in a variety of ways and often, by using several programming languages. Data stored on the databases can be accessed by many employees at the same point of time.

Lower Costs:
These systems are easy to understand and the money, time required for training the users is reduced. Time taken to process requests may be shorter, which would increase user productivity.

Redundant Data:
Data normalization is the process used by the organizations to minimize the data redundancy as all the items are stored only once in the database which stores space.

Backup and Recovery:
Centralizing a database provides the schemes such as recovery and backups from the failures including disk crash and power failures.

Restricting Unauthorized Access:
A DBMS provides a security and authorization subsystem, which is used by DBA to create user accounts and to specify restrictions on user accounts.

Changes to Schema:
In some databases tables in the system can be edited to add new columns and rows without hampering the applications.

Data Consistency:
DBMS provides consistent data to the users which includes accuracy, validity and integrity of related data.

DBMS has many advantages for an organizations, it simplifies the process of data entry, transaction and retrieval in an organization.

Why Urine Drug Test is Conducted More Commonly?

Identifying the drug abused persons is possible by conducting different types of drug testing. Among urine, saliva, blood, and hair drug tests, urine drug testing is more common. It is also the test which is federally mandated for conducting on-site tests and laboratory analysis. There are many reasons for its prominent use.

Urine drug testing can be conducted very easily. The kits that help in conducting the test are so simple in design and can be handled by any one. The procedures to be followed are mentioned on the drug testing product. All you need to do is to fill the testing product with few drops of collected urine sample. The test gives accurate and reliable results within 5 minutes. Urine drug test kits available in the market are manufactured in such a way that they work based on the Substance Abuse and Mental Health Services Administration (SAMHSA) cut-off levels. So 98% accuracy is associated with such urine drug test kits.

Urine drug test method can detect the drug usage for a maximum of two weeks from the time of abuse. It is the cheapest form of drug testing and is an economical option for conducting drug tests at workplaces, schools, and other organizations. Many illegal drugs like marijuana, amphetamines, cocaine, heroin, barbiturates, codeine, and many others. Also there are many multi-panel drug test kits that can detect different drugs at a time. It is less invasive when compared to blood drug testing. Due to the above said features, urine drug testing is done more commonly.

Disadvantages of Sweat Drug Testing Method

Drug testing conducted frequently on drug abusers is one of the ways to prevent them from being addicted. Among many different types of drug testing like urine, saliva, hair, and blood drug testing, sweat drug testing is one. But it is not used commonly. Sweat drug testing includes patches that are attached on the skin to absorb sweat. The drug or its metabolite is checked in the sweat of an individual. The patch is attached to the skin for over two weeks and then removed and sent to the laboratory for result. It is mostly used at places where urine drug testing is not practical or applicable.

There are even some disadvantages of sweat drug testing. One of the disadvantage is the high variability among individuals. The nature of the sweat of different individuals is different. This affects the results of drug testing. High chances of adulteration are associated with sweat drug testing. There are many chances that the patch is prone to environmental contamination before application or after removal. Also, there is a risk of accidental removal of the patch during the monitoring period.

It is to be made sure that the surface of the skin is cleaned thoroughly before placing the patch. The patch should also be handled carefully while attaching it to the skin. Otherwise the cellulose pad of the patch may get contaminated during handling. Any improper handling of the patch in the laboratory during analysis also affects the results. However, still many researches are being conducted to find the efficiency and utility of sweat to be used as a drug testing material.
