Investigations were undertaken to study the effect of different thermal environments of growth attributes of broilers. One hundred fifty-day old chicks of both sexes were kept each in control, foggers, exhaust fan and cooler groups during hot and dry, and hot and humid periods to assess the effect of cooling on growth efficiency of broilers in terms of(More)
An aqueous extract of human placenta, which is used as wound healer, has been investigated in terms of fluorescence properties. When excited at 340 nm, it results in fluorescence emission having maxima around 436 nm, which is fairly specific for nicotinamide adenine dinucleotide, reduced form (NADH) and nicotinamide adenine dinucleotide phosphate, reduced(More)
The possibility of finger printing of multi component drugs, where a number of components are fluorescent, has been explored after generation of excitation-emission matrix (EEM) contour plots. With nicotinamide adenine dinucleotide, reduced form (NADH) and N-acetyl tryptophanamide (NATA) serving as reference compounds, the contour widths were found to be(More)
Digital Microfluidic Biochip (DMFB) is a ground-breaking invention in many areas of Microelectronics, Biochemistry, and Biomedical sciences. It is also known as `Lab-on-a-Chip' for its performance as an alternative for laboratory experiments. Various types of diagnosis procedures are performed on it through a sequence of modular operations like sample(More)
The guard zone computation problem claims utmost importance in VLSI layout design, where the circuit components (or the functional units/modules or groups/blocks of different sub-circuits) that may be viewed as a set of polygonal regions on a two-dimensional plane, are not supposed to be placed much closer to each other in order to avoid electrical(More)
Tooth avulsion is the most serious dental injury that affects the pulp tissue, periodontal ligament and the alveolar bone. It is more frequent in children aged 7-14 years and mostly the maxillary anterior teeth are affected. Management of avulsed permanent tooth often presents a challenge. Replantation of avulsed tooth can be defined as the insertion and(More)
Counterfeit coin problem is of utmost importance and it is truly interesting in Computer Science and Game theory as well as in Mathematics. In this problem the objective is to detect the fake coin(s) of identical appearance but of different weight in minimum number of comparisons. The word counterfeit is most frequently applicable to forgeries of currency(More)
In recent times, microfluidics is expected to lead to sensor systems for high throughput biochemical analysis. One of the most advanced technologies to build a biochip is based on microfluidics where micro / nanoliter droplets are controlled or manipulated to perform proposed biochemical operations on a miniature lab, called lab-on-a-chip (LOC). Compared to(More)
