Opis:
Treatment of Municipal wastewater by Electrocoagulation (EC) process using punched aluminium and zinc electrodes was studied in a batch EC cell reactor. Response surface methodology (RSM) based on Central Composite Design (CCD) was utilized to optimize the operating parameters for the removal of % Total Suspended Solids (TSS) and % Chemical Oxygen Demand (COD) from Municipal Sewage. Effect of operating parameters such as Electrode Distance (x1), Electrolysis Time (x2) and Voltage (x3) has been optimized for the removal of TSS and COD. The prediction of removal percentage of TSS and COD in various Operational circumstances is done by using Quadratic model. The significance of each operating parameter was computed by Analysis of variance (ANOVA). To achieve the maximum removal of % TSS and % COD, the optimum conditions were Electrode distance(x1)-3 cm, Electrolysis Time (x2)-70.299 minute and Voltage (x3)-6.5V. It was observed that the performance of electrocoagulation process increased up to 61.45% for COD removal, and 73.73% for TSS removal using punched electrode compared to plane electrodes.

Opis:
A spin-valve transistor showing high sensitivity at low fields was developed. A large magnetocurrent, above 500% is realized by a magnetic field change of 2 to 4 Oe at 80 K. Hot electrons are injected into the spin-valve layer through a Si-Pt Schottky diode. These hot electrons, while traversing through the spin-valve, are spin-dependently scattered. Those electrons with right energy and momentum are collected by a collector (an Au-Si Schottky diode) constituting a collector current. The relative orientation of the magnetic layer in the spin-valve is changed by the application of a magnetic field and causes a change in collector current giving a large magnetocurrent.

Opis:
Low power VLSI designs are having wide variety of application usage in real-time. VLSI circuits are analyzed with various power reduction strategies. Existing approaches are used the clock frequency control, switching activity and scaling factor for power reduction. The glitching problem and clock triggering issues are higher therefore; the proposed work utilized the improved circuit of clock gating technique. In this proposed work, the enhanced clock gating with D-latch model is constructed to obtain the less power consumption. The traditional clock gating technique is improved by adding clock triggering on LATCH circuit and adding buffer circuit between the source and load circuitry to reduce the clock switching issues like gitching and clocking activity. Here the SRAM and sequential counter circuits are designed to utilize the power reduction strategy for improving the performance. This is applicable for various applications in real world and utilizing the FPGA and DSP application specific circuits. Experimental results are analyzed to obtain the power reduction result of SRAM and sequential circuit. Area, power, and delay are obtained the better results as compared with the previous work. Overall, design is performed using Xilinx 14.2 ISE suit.

Opis:
In the present research, the wear behaviour of magnesium alloy (MA) AZ91D is studied and optimized. MA AZ91D is casted using a die-casting method. The tribology experiments are tested using pin-on-disc tribometer. The input parameters are sliding velocity (1‒3 m/s), load (1‒5 kg), and distance (0.5‒1.5 km). The worn surfaces are characterized by a scanning electron microscope (SEM) with energy dispersive spectroscopy (EDS). The response surface method (RSM) is used for modelling and optimising wear parameters. This quadratic equation and RSM-optimized parameters are used in genetic algorithm (GA). The GA is used to search for the optimum values which give the minimum wear rate and lower coefficient of friction. The developed equations are compared with the experimental values to determine the accuracy of the prediction.

The paper reports meiotic studies on 50 populations comprising 12 species belonging to 5 genera of Caryophyllaceae from the Western Himalayas. The chromosome numbers in Arenaria kashmirica (n=20), Silene conoidea (n=20), S. edgeworthii (n=12 and n=24), S. moorcroftiana (n=24), S. nepalensis (n=12), Stellaria media (n=13), S. monosperma (n=13) and S. semivestita (n=13) are reported for the first time. The chromosome numbers in Lychnis coronaria (n=12) and Silene vulgaris (n=24) are given for the first time from India, along with Gypsophilla ceratioides (n=15) from the Western Himalayas. The course of meiosis varies from normal to abnormal in different populations of Silene conoidea, S. edgeworthii, S. vulgaris, Stellaria media, S. monosperma and S. semivestita. The course of meiosis was abnormal in all studied populations of Lychnis coronaria. Abnormal microsporogenesis (cytomixis, chromosomal stickiness, unoriented bivalents, formation of laggards and bridges) led to reduced pollen fertility and differences in pollen grain size.

Opis:
Erythina stricta is an ecologically important tree species in the rainforests of India and its nectar within the flowers contributes to birds’ diet and survival. Reports on the pollination of this species have not been published so far. We therefore explore the reproductive system of this tree species which has great significance to its ecosystem. Birds have an important role in the reproduction of trees through pollination particularly in tropical areas where reproductive success mostly depends on animal pollinator interactions. Study of visitation and nectar feeding behaviour of birds alongwith breeding system assessment of Erythina stricta. Birds visiting and foraging behaviour was observed during Erythrina stricta flowering season in an indian tropical rainforest. Reproductive system was assessed through controlled pollination experiments. Thirteen bird species were recorded visiting and foraging nectar from the flowers of Erythrina stricta. The maximum numbers of visits recorded were from the Red-vented Bulbul (Pycnonotus cafer, Pycnonotidae). The nectar feeding birds were, either (i) potential pollinator with long bills (e.g. Pycnonotus spp., Chloropsis aurifrons, and Dicrurus spp.) or (ii) nectar robbers with comparatively shorter bills (e.g. Zosterops palpebrosa, Stachyris ruficeps, Macronous gularis, Heterophasia glaciris). Controlled pollination experiments revealed high degree of cross pollination (xenogamy) and self-incompatibility in E. stricta. Birds were more frequent in early mornings and their foraging activity was also observed during evening hours; the frequency however, declined with respect to nectar availability. Long corolla tubes of E. stricta could restrict access to nectar collecting bees

The performances of the model have been evaluated in terms of gain and noise figures for the C-band (from 1525 to 1565 nm). Gain flatness (> 21 dB) is recorded with the least variation of 2.5 dB without using any cost effective technique. Further, the effect of the proposed hybrid optical amplifier has also been analyzed with slightly shifting the wavelength spectrum for the same feature.

Nano-biotechnology represents the intersection of nanotechnology and biotechnology which is an emerging field in creation, productivity and utility of nanoscale structures for advanced biotechnology. Plant and plant extract are considered as green and effective paths in the synthesis of gold and silver nanoparticles. The aim of the present study is to analyze the interaction of silver nanoparticles synthesized from herbal source (Cinnamon zeylanicum) with pathogenic bacteria Salmonella typhi (S. typhi) in order to know the microbe pathogenicity. The micro-nano interface disturbed the growth of microbes. Under the influence of different concentration of nanoparticles (50 µL to 1,000 µL), the microbes exhibited slow growth as compared to control. The viable cell count also decreased as the nanoparticles concentration increased. This shows major difference in the bacterial culture of with and without nano particle. Under normal culture, without nanoparticles intervention, the microbes show lag phase at 0-4 h, the log phase begins and its exponential growth occurs between 4-8 h and after 12 h, stationary phase was attained. There was a slow growth observed when the culture was exposed to silver nanoparticles. This clearly shows the antimicrobial effect of nanoparticles. In this study we used green synthesized nanoparticles, which have shown a good antibacterial efficacy against the pathogenic microorganism Salmonella typhi.

C₂ seeds of autotetraploids (colchicine-induced) of two diverse genotypes, T 163 and 5064-S, of pea (Pisum sativum L.) and their corresponding diploids were irradiated with 10 kR gamma-ray. Autotetraploids showed a high seed-sterility as compared to diploids. Seed fertility increased in M₂ as compared to M₁. Both quadrivalent and bivalent frequencies decreased in the M₁ generation of autotetraploids in relation to their respective controls. However, a positive shift in the mean bivalent formation was noted at the cost of other configurations in C₃-M₂ with respect to C₂-M₁ and varied with the genotype. In the M₂ generation of autotetraploids, the variability was relatively higher for the number of pods per plant and seed yield per plant. Although the mean values for pods per plant, number of seeds per pod and seed yield per plant remained more or less parallel in autotetraploids in M₁ and M₂ generations, there was an increase in the upper range limit probably due to micromutation for these characters in M₂.

Opis:
Background. Bisphenol A (BPA) is a product in the manufacture of Bis-GMA, which is commonly used in dentistry, and is known to have a number of adverse effects. Objectives. The aim of this study is to evaluate to assess the knowledge, attitude and practice based on exposure and handling of BPA containing materials among dental surgeons for better understanding about the level of care rendered to the patients. Material and methods. A questionnaire survey was conducted on 400 dental surgeons in Southern India. The questionnaire consisted of 20 objective type questions out of which ten questions assessed knowledge and five questions assessed the attitude and five questions to understand the practice related measures taken by the dentist. The data collected were analysed using SPSS version 23. Results. A total of 402 responses were collected for this online questionnaire survey over a period of 2 months. It was found that females showed higher knowledge and attitude towards exposure to BPA which was statistically significant when compared to males. It showed that dentists with more than 20 years of practice had a higher level of knowledge. Though most of the groups agreed fairly on safety practice to be undertaken related to BPA exposure in their clinics, the ones with experience more than 20 years displayed the least positive attitude and dentists with 6-10 years of practice had the least positive behaviour among all. Conclusions. In spite of having a good knowledge regarding the harmful effects of BPA, dental surgeons are not very cautious while using materials containing them on a regular basis. Therefore, there is a need to enhance the awareness with the help of Continuing Dental Education programs or proper instructions on the packaging.
