The water quality problem in India is severe in many states of the country. It has been discovered that there are relatively less initiatives toward dealing with the issues related to water top quality by Govt., and other organizations in India. We have examples where the youth could not find jobs in organizations or public sector organizations those take wellness and fitness test by looking in each parameter of wellness of a person.
In today’s ‘Information Society’, e-resources have become an accepted means of information source. They are quickly becoming more and more important in today’s world in view of the fact that, they are: (a) more up-to-date, (b) accessed almost anywhere and most importantly crossing all time zones and geographical boundaries. These e-resources add enormous value while conducting R&D activities. These resources, especially in context with special libraries are making a great impact and important contribution as part of the library collection and information dissemination, One such important eresource which aids as an important tool ‘Information Dissemination Channel’ are the Digital Libraries. In other words, Digital libraries are ‘scholarly communication transmission channels’ of making educational and research data and information available to faculty, researchers, students, and others at various institutions and worldwide. Today, in the Internet era, the conventional and long-established methodologies of collecting, storing, processing, accessing and retrieving information have undergone a paradigm shift due to the arrival and growth of (a) virtual libraries, (b) digital libraries, (c) online databases, last but not the least, (d) library and information networks.
The present work deals with the development of miniatured electrochemical biosensor, an enzyme electrode for monitoring insulin. The purpose of study was to develop miniature enzyme electrode with good sensitivity, micro sampling, and medical application and cost effectiveness. The present study comprised of 90 subjects categorized into three groups: group 1- normal individual, group 2 - non-insulin dependent diabetic mellitus patients (NIDDM), group 3- insulin dependent diabetic mellitus patients (IDDM). Insulin levels were monitored on three different transducers using screen printed enzyme electrode. The enzyme electrode was prepared by immobilization of red blood cells (RBC) with the covalent cross linker glutaraldehyde and along with the silanization with 3-aminotriethoxysilane. The signal was monitored on three different transducers i.e. polarograph, amperometer and photofluorometer. The current response for the electrode was proportional to the insulin concentration and the response time was 25 mins. The lower detection limit of insulin was 0.06 nM. The stability of the immobilized biocomponent on screen printed electrode (SPE) was for 24hrs at 4º C. The screen printed enzyme electrode is disposable in nature. The analysis of insulin by miniaturization approach is a remarkable step far ahead of the old conventional method of electrochemical detection with a lower detection range. The developed miniature enzyme electrode had been applied for determination in normal subjects, non-insulin dependent and insulin dependent diabetic mellitus patients.
Pigmentation discovered in vegetation and violet parasites applied to shield you from sun harm do more than just that. Scientists from the School of Greater and School of Glasgow have discovered that they also help to collect light energy during photosynthesis.
The Silent sound technology is a perfect solution for those people who have lost their voice but wish to speak on mobile phones. This technology helps to detect every lip movement and converts the electrical pulses into sounds signals and sends those signals avoiding the surrounding noise which may cause disturbance. This is going to be a good solution for those who have lost their intensity to speak. The main aim of ‘Silent Sound’ technology is to notice every movement of the lips and convert them into sound so that the information can be transferred in audio form, which could allow people to make silent calls without bothering about other people. Rather than making any sound, your handset will transfer the movements your mouth makes which will measure the muscle activity with the help of that handset then convert this into audio speech that the person can hear on the other end of the call on phone. So, it reads your lips. This new technology will be very helpful whenever a person loses his. voice while speaking and it also allows people to make silent calls without disturbing others. This technology can also be used in the military sectors for sharing secret matters with other people. It provides a PIN number which can be given to a trusted person so that the listener can hear a clear voice on the other end.
The herbal composition containing natural source of lysine was examined to assess its efficacy in terms of growth, haemato-biochemical, pathological and carcass quality attributes. Seventy five healthy day old broiler poultry chicks of nearly similar live body weight were equally divided into three groups, comprising twenty five chicks each.
The great clam, Meretrix meretrix is a major contributor in the clam catches along the south west coast of Maharashtra, India. The colour and shape of the shell are generally used as the identifying characters of the clam, but these characteristics mainly depend on the habitat and food availability and may show variation accordingly. Present work analyses the relationship between the total shell length to shell width, shell height and hinge length. The morphometric equation for the samples collected were Ht = 2.713 + 0.054 L, Wd = -0.9034+ 0.8963 L and Hg = -1.3926 + 0.30 L.
Chittagong University (CU) is a public university, known as the cleanest university of Bangladesh due to its neatness and overwhelming presence of green trees and hilly landscape. But now due to indiscriminate solid waste disposal and improper waste management, the cleanliness of the university has been facing serious problem. The study was conducted at Chittagong University campus to determine the generation rate, physical composition and characterization of solid waste and find out current situation of solid waste disposal and management in the campus. Total solid waste generation in CU campus was 1509 kg per day and the generation rate 0.17 kg per person per day. Waste generation from 12 colonies, 6 staff quarters, 3 residential areas, 9 halls & 2 hostels (including Pagoda), 6 faculties (including 1 college and 3 schools), commercial areas (125 shops and restaurants) and 7 offices were 500, 144, 162.22, 363.97, 78.71, 197.50, and 31.52 kg and waste generation rate by individual category 0.16, 0.21, 0.29, 0.08, 0.004, 1.58, and 0.05 kg per day respectively. Total amount of recyclable and non-recyclable waste generation was 416.20 kg (28%) and 1092.79 kg (72%) per day respectively. There are 64 dumping sites found in the campus, most of these are unhygienic and becomes very risky for sound environment of the campus. Therefore, it is inevitable to take immediate steps by University authority to improve environmental condition of University campus through effective solid waste management.
Dinosaurs are often believed of as huge, intense creatures, but new analysis features a formerly neglected variety of little dinosaurs. The Published work in Journal of Vertebrate Paleontology, a group of paleontologists from the University of Toronto, Royal Ontario Museum, Cleveland Museum of Natural History and University of Calgary have explained a tiniest plant-eating prehistoric variety known from North America. Albertadromeus syntarsus was recognized from a limited back leg, and other skeletal components, that indicate it was a rapid sprinter. Roughly 1.6 m (5 ft) long, it considered about 16 kg (30 lbs).
A study was undertaken to check the protagonist possessions of thermophilic bacteria in defect development under prolonged incubation of packed milk pouches at 55oC temperature for 36 hours. Total thermophilic count, Total Mesophilic count, Coliform, Yeast and Mold along with MBRT tests were conducted at the time interval of on hour. The bell shaped graphical growth pattern was examined for the parameters including total thermophilic count and total mesophilic count. The counts initially increased up to 25 hours and gradually reduced at the end of 36 hours. Total viable cells also affect MBRT time resulting in to “U” shapedgraphical pattern examined for the MBRT test. Coliforms were not detected in initial hours but examined its presence in mid hours between 6th to 20th hours, which were gradually reduced and vanished due to accumulation of acid and gas resulting in to imbalance of pH. It was also observed that fungi did not tolerate 55oC temperature and disappeared gradually due to lack of adaptation resulting in to impotent to cultivate at 55oC temperature after 5 hours. Pure, partial or combined influence of total microbial activity at 55oC temperature in pasteurized milk leads to development of numerous sensory defects including acidic flavour, bitter taste, inexpressive and unpleasant flavour along with physical defects like gassy curd formation and bulging effect on packaging materials progressively.
Mild steel coupons of different dimension 3x3x0.014 cm were suspended in a beaker containing 200 ml of inhibitor/blank solutions maintained at 303 K and 333 K in a thermostated water bath. The weight loss was determined by retrieving coupons from test solutions at 3h interval. The difference in weight was taken as weight loss of mild steel. The study revealed that inhibition efficiency of extracts increases as concentration of extracts increases. The inhibitor was found to function by being adsorbed on surface of mild steel. This study revealed that inhibition efficiency decreases as temperature increases. The adsorption of inhibitor on mild steel surface followed Langmuir and Flory- Huggins adsorption isotherms. The inhibition efficiency of different extracts werein order: Distilled H2O> C2H5OH> Petroleum ether.
