With the advancing neuroscience technology it will soon become possible to enrich the excellence of an individual with better brain performance .Thorough understanding of the brain and its different elements will assist scientist to invent better therapies, technology and medical treatments for better brain recovery and operation.
Ajax Technology
Ajax technology introduction:
Ajax (asynchronous JavaScript and XML) technology is being increasingly popular in website design. Using ajax technology you can submit form data to the server without refreshing the document. Suppose you are filling an online registration form. You write your user name, email address, address etc. and submit that form. At the server end server detects that the user name has already been taken by another user. So it will generate an error message and request you to choose different user name. Now you have to fill the entire form again unless the server brings your data back to you through query string. Moreover it is not very safe to send your personal information through query string. In such case data submit by ajax technology is the best solution. Another useful feature of ajax technology is that you can send custom data (like user IP) which is not in the form field.
Like conventional data submission ajax data submit also of two types, GET and POST.
There relative merits demerits are same as conventional data submission.
How data is submitted using ajax:
1. When user submits data by pressing submit button or by clicking submit link a JavaScript function is called.
2. This function establishes connection with the server by XML HTTP REQUEST object. When connection is established data from the form fields are transmitted to the server.
3. Whenever the server response is received another JavaScript function is fired. This function then takes the necessary steps according to the response text from the server end.
Ajax Advantages and disadvantages:
1.
As whole page is not reloaded ajax submission is faster than conventional form submission process.
2. It is more users friendly.
3. Use of ajax technology is not limited to form data submission. It is widely used in dynamic menu design; collecting data for web stat analysis, or even reload the entire page dynamically.
4. Some users disabled JavaScript of their browser. In such cases ajax fails to work.
5. As data are dynamically loaded web history is not available, i.e. you can’t reload page by using back button of your browser.
NIR Technology
NIR spectroscopy or Near Infra Red Technology is a tool used to precisely analyze food components and the prediction of functionality parameters. This tool is very useful for the Food technologists at any level. The future uses of NIR technology include grading and classifying materials and organoleptic-type categorization of materials and foods. NIR technology focuses on the development of technical knowledge and practical applications of this spectroscopic technique. NIR instruments were initially developed to conduct grain quality analysis in the field at low cost.
NIR technology procedure includes the use of probes or flow cells for a direct investigation of the most relevant processes to analyze substances that contain CH-, NH-, OH-, SH- or -C=O groups in a concentration range of approximately 1% and above.
NIR instruments can be used to analyze both solid and liquid samples (during extreme conditions as well) with the development of modern probes and transmission cells.
The use of NIR instruments does not require sampling as necessary in the analysis performed by the qualified technicians. The spectroscopic information is easily transportable via fiber optics over distances of more than 100m to the instrument.
At present, the NIR instruments can be used to analyzer products in the field, laboratory and on line. NIR Technology Systems are being used to analyze the quality of food, agriculture, cosmetics, and pharmaceuticals, chemical, plastic and polymers. The NIR Technology Systems use state of the art gratings and diode array detection for analysis. These analyzers come with the software which helps in analyzing the qualitative and quantitative parameters using the partial least squares calculation.
NIR instruments are also used by the defense departments to prevent detection by NIR Image Converters which helps in not detecting the body temperature, but help in detecting the infrared radiation variances.
The NIR technology uses infrared radiation which is basically electromagnetic radiations whose wavelength is longer than that of the visible light, but shorter than that of terahertz radiation.
If we consider the Planck’s law, it states that the objects or surfaces give out an electromagnetic radiation whose intensity and spectral distribution depends on the body’s temperature.
Many detectors for the near-infrared spectral range of 0.8µm to 1.1µm can detect thermal radiation from temperatures of approx. 300°C on surfaces. This temperature cannot be seen by the human eye .
NIR technology can also be used to detect electromagnetic radiations just like an alarm system can detect smoke. Scattering of light by aerosols in this wavelength range is even less than in the visible range. Therefore in many situations open fires can be localized through smoke when it is not possible with the human eye.
Understanding DNA Technology
Without a doubt, DNA technology has revolutionized the world of science. Scientific fields of biochemistry, genetics, biology and even forensics have been changed by the use of this powerful technology. Deoxyribonucleic acid, otherwise known as DNA, is an organism’s genetic material. This technology has solved many mysteries behind evolution, diseases and even human behavior.
DNA technology is also being widely used to verify biological relationships and the identity of individuals living or deceased. Major advances in DNA profiling have enabled DNA tests to be completed in just a short time.
There are many technologies used in DNA testing. The most common of which are Electrophoresis, Short Tandem Repeats (STRs), Polymerase Chain Reaction (PCR), Mitochondrial DNA Sequencing (mtDNA Sequencing) and Restrictive Fragment Length Polymorphism or RFLP. A brief description of each technology is provided below.
Electrophoresis is a technique in separating DNA fragments according to size by introducing an electric field into the DNA molecule. The DNA molecule is set on a viscous medium, referred to as the gel. Longer and smaller molecules are separated because of their different abilities to pass through the gel.
Short Tandem Repeats (STRs) is a type of DNA analysis performed to examine specific areas in a DNA. Each individual has differences in certain DNA regions. These differences are used to ascertain the identity of an individual.
Polymerase Chain Reaction (PCR) is a technique used to create precise DNA replications. Millions of replications are created thereby allowing DNA analysis to be performed on samples that are extremely tiny such as a couple of skin cells. The sample though must not be contaminated by DNA of another source.
Mitochondrial DNA Sequencing (mtDNA Sequencing). There are two types of cells in a DNA – nuclear DNA and mitochondrial DNA. There are cases wherein a sample is too old and no longer has nuclear DNA. mtDNA Sequencing is a technique used to recover mitochondrial DNA. Forensics uses this type of technology on cases that have been unsolved even after so many years.
Restrictive Fragment Length Polymorphism (RFLP) DNA technology is one of the first technologies used in DNA analysis and is no longer widely used.
RFLP analyzes different lengths of DNA fragments from the digestion of a sample with a restriction endonuclease enzyme.
