REASONS TO TEST YOUR BATTERIES
What is the capacity of your battery just now?
When will you have to change your battery?
What can you do to improve the life expectancy for your battery?
These are the principal questions because you should perform discharge test to your batteries. The batteries are composed of electrochemical cells. The fabrication technology for these products is complex, so it is not strange to find manufacturing faults. On the other hand, the degradation of the batteries is inevitable. In order to avoid unexpected costs stem from a fail in your batteries, it is important to schedule preventive maintenance for batteries in your company. That's why it is so advisable to know the answer to the previous questions at every time. The BATTERY DISCHARGE TEST is the most simple and efficient way to analyse the main parameters of your batteries.
ABDX FEATURES
The ABDX battery discharger purpose is to check the efficiency of any type of battery. It is a versatile device, based on MOSFET or IGBT technology (depending on the size of the discharger), it can be used with batteries of any technology and voltage/capacity. The ABDX controls automatically the discharge current and keep it constant, so the total capacity of the battery can be easily calculated once the test is finished.
The following test parameters must be introduced before performing the test:
Stop voltage
Maximum time allowed for test
Discharge current
Then, the test runs automatically until the STOP VOLTAGE or MAXIMUM TIME is reached.
The following parameters can be visualized on the display during the test:
Capacity discharged
Time
Battery voltage
Current
Programmed stop voltage
It is easy to download the test data to a computer and to make graphics and reports with the provided software.

Forensic Science: The Basics
With a large number of criminal investigation shows on TV such as CSI, Criminal Minds and Bones, many people have become fascinated with the forensic science profession. Many do not realize, however, the hard work and dedication that this position requires. Not only is this field extremely competitive, but organizations that work with people in this field look to hire only the best. With that being said, the educational requirements are beginning to get stricter as more and more people are trying to break into the field.
The forensic science field, otherwise known as forensics, includes the use of an extensive range of sciences in order to answer questions that the legal system has, usually regarding a crime of some sort. The legal system turns to them for help with identifying and convicting criminals. It their examinations and findings of forensic data that regularly verifies whether or not the suspects in a crime are guilt or innocent. Their responsibilities include observing the information and evidence of a crime and writing down their findings in order to provide a statement of their discoveries to a court of law. Other tasks include performing physical and chemical investigations on criminal evidence provided by some type of law enforcement organization which can be found at the scene of a crime, on a victim, in some cases, both. People in the forensic science field use an assortment of problem-solving techniques, mathematical ideologies, intricate tools, and microscopic probing methods to clarify the particulars of each part of evidence from a case.
There are a number of different positions that someone in the forensic field can have. Some work in strictly in laboratories testing all the evidence that was found, while others work directly at the scene of the crime in order to collect their analysis. Focuses of the area include clinical work, research, communication, computer sciences and much more. Some people in forensics chose not to specialize in a specific area, but would rather be considered a generalist. Most that choose this option are involved in a number of different tasks involving forensics or are involved in a new or rare forensic area of expertise.
Most people that are in the forensic profession work directly with the law enforcement run by city, county or state governments. If people are lucky enough, they can also work for several federal agencies including the Federal Bureau of Investigation; the Secret Service; the Drug Enforcement Administration; the Bureau of Alcohol, Tobacco, and Firearms; the U.S. Postal Service; Health and Human Services; and the Criminal Intelligence Agency. Additionally, forensic scientists may be employed by other organizations outside of the government. They may chose to work in private forensic labs, medical examiners offices, hospitals, toxicology labs, medical examiner or coroner offices, colleges and universities, or as independent consultants.
People in forensics have a tough occupation and in order to stay current on all the new technology and methods, they are often encouraged to take a path of higher education. Unfortunately, the education and training requirements are different for every forensic position and for every state, but almost everyone in the forensic profession has earned at least a bachelors' degree. Many chose to earn their bachelors' degree in biology, chemistry or physical anthropology if their college of choice does not offer a forensic science program. An important factor that people interested in the forensic science fields should know is that the title of the degree they earn is not nearly as important as the courses they take throughout their education. Prospective forensic scientists should take college courses that give them experience in a lab and technological setting, such as biology, chemistry, physics, quantitative analysis, toxicology, computer sciences, psychology, criminal justice courses and statistics.
Depending on the forensic position someone is looking for; they may also be required to further their education by enrolling in a graduate program. Most graduate programs are more specific and will include different divisions of forensic science; therefore, this is the time when most students decide what to specialize in. Many programs allow students to focus on areas such as forensic archeology, forensic pathology, or body identification. Many times, labs require a person to get a masters degree for advanced positions in the forensic field such as a lab technician leader or supervisor, or someone who specializes in DNA analysis or ballistics. Most positions only require a masters' degree; however, people who are interested in teaching should continue on to earn their PhD. Also, everyone in the forensic field are expected to continuously update their training in order to maintain their various certifications and to keep current with all of the new tools, technology and techniques used in the field.
And now, higher education institutions have made it even easier for people to earn a degree in forensic science. A number of schools have created online degree programs that allow students to earn their associates, bachelors or masters degree without having to ever step foot on a college campus. Online programs allow students to complete their work on their own time, which is great for those people who have a full time job, or a family and do not have time to attend class through a traditional college setting. Online programs also benefit students who live in areas that do not have a college nearby. Students could possibly earn their degree from a college that is all the way across the country, if they wanted. That means that students have more options for deciding what degree program is right for them and will give them the best quality education for their specialty. Also, many times online degree programs cost less than a traditional degree program and take less time to complete.
Public Service Degrees has recognized that many people desire the opportunity to go back to school, so we have teamed up with a number of regionally accredited colleges all across the country to help those people reach their goal. All of the programs we offer are 100% online and are offered by colleges that are known for their quality education. Public Service Degrees has several programs specifically for people interested in forensic science, such as a BA Social and Criminal Justice-Forensics or an MBA in Criminal Justice.

Challenges Facing Part Time Lecturers In Institutions Of Higher Learning
Education is central to development as it empowers people and strengthens nations and hence it is critical to nation's development. Investment in education benefits the individual, society and the world as a whole. A broad-based and good quality education is among the most powerful instruments known to reduce poverty and inequality. Quality education can only be achieved in a university. Quality is a good academic training based on good knowledge transfer, a good learning environment and a good relationship between teaching and research. This implies that the quality of the lecturer (who transfers knowledge and sets the learning environment) is a critical component of quality university education.
Lecturers find themselves moonlighting in addition to their full time work while others who are part time in one institution add work in other institutions. The reasons for moonlighting include the need for extra income, career development, meeting the needs of understaffed departments and changing environments.
However, part time lecturing on top of regular work comes with various challenges.
First, the lecturers have no forum for airing their concerns and these impacts negatively on the teaching/learning process. They remain docile in an environment that requires open interaction with their full time counterparts. Second, it is difficult to balance between full time and part time work thereby making it hard to plan for the available time. In addition, they are never sure of getting part time teaching and as such they cannot predict how to plan their time.
Third, accurate payments, low payments and being paid on time are a big challenge. They do not benefit from institutional deductions for medical cover, car loans, computer loans, annual leave, pension scheme and insurance cover. Payments are irregular and there are delays that sometimes take two to three months particularly at the end of the semester. Four, lack of choice of friendly courses for part time teaching means that lecturers are not imparting the right knowledge to the students. They are sometimes given courses that remain unallocated to full time lecturers and these may not be in their strong areas of specialization. To avoid doing without a course to teach they accept them because they cannot choose for themselves what they desire to teach. Five, these lecturers are overworked when they move from one institution to another and taking too much workload. Chances of taking many courses are there because there is no system of monitoring the loads they have elsewhere.
In addition, they lack time to prepare for lessons, administer assignments and mark to beat the deadlines for the various institutions. Six, commitment to one's work is important for good service delivery. Part time lecturers, however, are never committed to the institutions they work in for once they are through with their teaching they leave. They cannot be expected to be loyal to the dictates, vision and mission of these institutions because they are there for a short while only. The worst scenario is when part time lecturers feel unwanted by their full time counterparts; sometimes even looked down upon and discriminated against.
To alleviate the problems of part time lecturers, universities should employ more full time lecturers from amongst the part time lecturers to achieve the university's mission and attract more students.

College - Tips For Choosing a Course of Study in College
Getting accepted into college can be a very confusing time. That is if you're not certain what to pursue. With so many courses and specialties to choose from, how do you know which is best for you?
Choosing a course of study should be carefully measured to avoid wasting four years on academics that will be useless once you graduate. Numerous studies conducted by the Bureau of Labor Statistics point to 60% of graduates working outside their majors. What does this figure signify? It either means low employment rates in the field, or students pursuing another field of passion.
Here are tips for choosing a course of study in college:
Income - Research what's the average income in the field. Many students do not think about how lucrative a degree will be. However, the bottom line of getting a degree is to earn financial security.The Job Market - The Bureau of Labor Statistics provides in-depth insight into job prospects for different fields of study. It usually includes a ten year forecast, and as an example, specific technology jobs like Network And Computer Systems Administrators can anticipate a median salary of $69,160, with a 28% growth between 2010-2020.Student's Interest - What did you want to become when you were growing up? Do you still have that dream? Chances are, students will be much happier working in a field they're passionate about. Aside from financial benefits, the student's core values, interests and beliefs will translate directly into the field of work. Confucius was right when he said "Choose a job you love, and you will never have to work a day in your life."Take a Personality Quiz - Experts recommend this test to determine if students are better suited working as a blue or white collar worker, based on his or her personality and interests.The Factor of Time - Some courses require a greater timeframe for completion. Examples include degrees related to medicine and law. As a new student, it's important to figure out if an extended course length will be an issue, and whether dedication is key.Talk to a Pro - Who will better advise all the necessary procedures to take, in order to select the best course for students' careers. Each online college should house a counselor for this purpose.
Rather than having a change of heart half-way through the online university program, students can begin by weighing these options to make the most practical choice.
