Design of 2-4 decoders and 4-16 decoders using GDI technique

This paper introduces a mixed-logic design method for line decoders, combining transmission gate logic, pass transistor dual-value logic and static CMOS. Two new topologies for the 2-4 decoder are 14-transistor topology and 15-transistor topology. 14-transistor topology based on the small size of the transistor, transistor count and power dissipation, 15-transistor topology based on high power-delay performance. Both non-inverting and inverting decoder are designed in every case thereby yielding a total of four new designs. Moreover, four new 4-16 decoders are designed, by using mixed-logic by cascading of 2-4 pre-decoders with static CMOS post-decoder. All proposed decoders which reduce transistor count and has the full swinging capability compared to conventional CMOS. GDI gate diffusion input analyses to design low power combinational circuits where we can overcome the disadvantages of CMOS, low power techniques.GDI technique helps to reduce power, propagation delay, transistor count, maintains the low complexity of designs. All proposed decoders are designed in Gate diffusion input (GDI)—a new technique of low-power digital combinatorial circuit design thereby results in reducing power consumption, propagation delay, and area of digital circuits while maintaining the low complexity of the logic design.

Analytical method development of mixed pesticide Mesotrione 4% + S -Metolachlor 40% + Benoxacor 2% SE by HPLC analytical technique

A simple reverse phase liquid chromatographic method has been developed and subsequently validated for the Mesotrione + S -Metolachlor + Benoxacor combination pesticide molecule. These molecules mixtures have been used as an effective weedicide, microbial control effectively in the presence of a chemical. The combination products Mesotrione + S -Metolachlor + Benoxacor is being used as a pesticide to manage at a time soil, crop plants, and weed management effectively. Such an important application of these combination products has fairly few analytical methods. These Mesotrione 4% + S -Metolachlor 40% + Benoxacor 2% molecules were separated through a mobile phase consisting of the mixture of acetonitrile and water in the ratio of 80:20 (v/v). The Column used in this separation is Shimadzu BDS C18; 250 mm length; 4.6 mm diameter with 5μ particle size dimensioned column; Flow rate: 1.0 ml/min; Detector: UV-Vis. Absorption (λ) at 230 nm of Shimadzu HPLC (model: LC-2030). The LC solution software was used for the analytical method, data integrations, and calculations in this analysis. There are two molecules were analyzed for separation and quantification. The results of the study showed that the proposed HPLC method is simple, rapid, precise and accurate, which is useful for the identification and quantifications of these molecules interims of validation parameters viz., separation, system suitability, System Precision and linearity in a simple HPLC analysis.

On g#-semi-open fuzzy sets and fuzzy g#-semi-irresolute maps in fuzzy topological spaces

In this paper, the class of g# s-closed fuzzy sets are introduced. This class properly placed between the class of semi-closed fuzzy sets and the class of gs-closed fuzzy sets in fuzzy topological space. Further, the concept of fuzzy g# s-continuous, fuzzy g# s-irresolute mapping, fuzzy g# s-closed maps, fuzzy g# s-open maps and fuzzy g# s-homeomorphisms in fuzzy topological spaces are also introduced, studied and some of their properties are obtained.

Review Paper

Diversity of medicinal flora in and around Kolleru lake

Kolleru Lake is the largest freshwater lake in India, located between West Godavari and Krishna districts of Andhra Pradesh. Being the largest freshwater body, Kolleru Lake supports rich aquatic medicinal flora and as an elevated land between Godavari and Krishna rivers, it provides good habitat for many terrestrial medicinal plants. At the time of the floristic survey, this study identified 11 aquatic and 24 terrestrial flora in Kolleru. In and around Kolleru area 35 medicinal plants were reported from 17 sites, out of 35 medicinal flora, 11 aquatic flora and 24 terrestrial plants were identified. Aquatic medicinal flora including Ipomea aquatica, Nymphaea nouchali, Nelumbium species, Salvinia cumulata Alternanthera sessilis, Typha angustata, Cypress rotundus, Ecilipta alba, Scripus articilum, Cynodon dactylon, Utricularia species was identified in Kolletikota, Gudivakalanka, Atapaka, Pedayadlagadi bridge. Terrestrial plants like Aerva lanata, Andrographis paniculata, Asystica gangetica, Abrus precatorius, Achyranthes aspera, Cassia occidentalis, Euphorbia hirta, Gloriosa superba, Hemedesmis indica, Tridax procumbence, Oscimum sanctum, Ricinus communis, Vitex negundo, Rauwolfia serpentina, Bixa octandra, Sida acuta, Abutilon indium, Acalypha indica, Tephrosia purpurea, Centella asiatica, Coccinia indica, Boerhavia diffusa, Crotan banplandianum, Phyllanthus madraspatens were identified in belt villages of the lake. During the last two decades, water quality and other environmental changes in Kolleru Lake resulted in stress on the biodiversity of the ecosystem. If these medicinal plant species properly maintained, harvested and marketed then it can be another source of livelihood of Kolleru area.

Bioavailability and Bioequivalence study of different brands [Telma (Glenmark), Telsartan (Dr.Reddy’s), Indetel (ZydusAlidac), Telmikind(Mankind)] of Telmisartan

Bioavailability and bioequivalence studies play a major role worldwide and thus attract considerable attention globally in the development phase for both their new drug products and generic equivalents. Bioequivalence is a revolutionary strategy to introduce generic equivalents of branded drugs to lower the cost of medication through proper assessment as directed by the international regulatory authorities. The present study had been performed to explore interchangeability of branded generic drug products by comparing their bioavailability via in vivo study of four different brands. For each study period a set of 12 subjects completed both period with a 1O-day washout period. In both studies, the study formulations were administered after a 1O-12 hour overnight fast. For pharmacokinetic analysis, blood samples were drawn at baseline, O.25, O.5, O.75, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12 and 24 hours after administration. Plasma concentrations of telmisartan were determined using HPLC coupled with a UV detector. All formulations were considered bioequivalent when evaluated against 9O% CI for the mean ratios were within the predetermined ranges of 8O% to 125%.in study the ratio analysis of AUCO-t for T1, T2 and T3 were 96%, 99% and 91%; Cmax was 98%, 99% and 95%; AUCO-T was 98%, 1O1% and 92%; AUCO-∞ was 1O8%, 112% and 87%; and Kel were found 1O2%, 1O6% and 1O5% respectively. In both studies periods, All Test formulations met the regulatory requirements to assume bioequivalence, based on the rate and extent of absorption.

Review Paper

A review article on comparative analysis of DEEC protocol

Energy Management can be improved by proficient clustering algorithms in heterogeneous wireless sensor networks. Coordination through cluster head selection provides efficient data aggregation that reduces communication overhead in the network. In this paper, we propose a fuzzy logic approach based DDEEC clustering algorithm which aims to prolong the lifetime of nodes in heterogeneous WSNs. We compare this algorithm with the PSO based DDEEC algorithm and original DDEEC algorithm according to the parameters of the first node dies at different rounds and energy-efficiency metrics. The efficiency of the proposed optimized fuzzy algorithm is proved by the Matlab experimental results. Simulation results exhibit that the proposed algorithm has higher energy efficiency and can improve the lifespan of a node and data delivery at the base station over its comparatives.
