Attenuation characteristics of monolayer graphene by Pi-and T-networks modeling of multilayer microstrip line

引用

Journal of Semiconductors 2017年第9期38卷 25-30页

作者： Pulkit Sharma Sumit Pratap singh kamlesh Patel Department of Electronic Science University of Delhi South CampusBenito Juarez RoadNew Delhi-110021India

The impedances of Pi- and T- networks are obtained from the measured S-parameters of the multilayer microstrip line by modeling as an attenuator. The changes in impedances have been analyzed for the properties of various superstrates at the microwave ranges. With graphene on glass and graphene on quartz loadings, the impedances have increased and shifted towards lower frequency more in Pi-network than T-network modeling. This shift has become more prominent at higher frequency for the graphene on glass than graphene on quartz. A little increase in attenuation is found for graphene on glass or quartz than bare glass and quartz. The present study can be extended to obtain attenuation characteristic of any thin film by simple experimental method in the microwave frequencies.

Apply AHP for Resource Allocation Problem in Cloud

引用

Journal of Computer and Communications 2015年第10期3卷 13-21页

作者： Avtar singh kamlesh Dutta Department Computer Science Engineering National Institute of Technology Hamirpur India

Cloud computing is an emerging paradigm with many applications that are integrated with IT organization having the freedom to migrate services between different physical servers. Analytic Hierarchy Process (AHP) with a pairwise comparison matrix technique for applications has been used for serving resources. AHP is a mathematical technique for multi-criteria decision-making used in cloud computing. The growth in cloud computing for resource allocation is sudden and raises complex issues with quality of services for selecting applications. Finally, based on the selected criteria, applications are ranked using the pairwise comparison matrix of AHP to determine the most effective scheme. The presented AHP technique represents a well-balanced multi criteria priorities synthesis of various applications effect factors that must be taken into consideration when making complex decisions of this nature. Keeping in view wide range of applications of cloud computing an attempt has been made to develop multiple criteria decision making model.

Structural and Ion Transport Studies in (100-x) PVdF + xNH4SCN Gel Electrolyte

引用

Materials Sciences and Applications 2011年第7期2卷 721-728页

作者： kamlesh Pandey Mrigank Mauli Dwivedi Nidhi Asthana Markandey singh Shanker Lal Agrawal 不详

In order to obtain highly conductive polymer gel electrolytes for electrochemical devices, Poly (vinylidene fluoride) (PVdF) based gel electrolytes namely (100–x)PVdF + xNH4SCN electrolyte system has been synthesized by solution cast technique and characterized by XRD, DSC, IR, SEM and electrical measurements. IR study of gel electrolytes shows interaction of PVdF matrix and dopant salt with prominence of α-phase. This result is also well supported by XRD and DSC studies. The electrolytes are electrochemically stable within ± 1.5 V. The optimum bulk electrical conductivity for 90PVdF + 10NH4SCN electrolyte has been found to be ~ 2.5 × 10–2 S●cm–1. Dielectric relaxation behavior shows low frequency dispersion and αc-related relaxation peak is observed in loss spectra. Polarization behavior of gel electrolyte shows ionic nature of charge transport (Tion. > 0.90). The temperature dependent conductivity shows VTF behavior.

Advances in Breast Cancer Research 2021年第4期10卷 218-233页

Male Breast Cancer (MBC) has a familial component thus identification of polymorphic risk alleles of candidate genes and/or cytogenetic anomalies may help to predict the risk for the offspring of MBC patients. The conventional metaphase cytogenetics can indicate loci that are hotspots while analysis by single nucleotide polymorphism arrays (SNP-A) can identify chromosomal defects which may play a role in the etiology of cancer. A cumulative genotype risk due to each allele of candidate genes of the signaling pathways regulating c-MYC, HIF1A, TP53 and BRCA1 may be a factor facilitating cancer development. Cancer risk was assessed in a 35-year-old healthy son of a 60-year-old MBC patient with a family history of cancer by metaphase cytogenetics, SNP-A and analysis of 25 polymorphisms in six genes TP53, MDM2, VEGF,

Induced Accumulation of Polyphenolics and Flavonoids in Cyanobacteria under Salt Stress Protects Organisms through Enhanced Antioxidant Activity

引用

American Journal of Plant Sciences 2014年第5期5卷 726-735页

作者： Dhananjaya P. singh Ratna Prabha kamlesh K. Meena Lalan Sharma Arun K. Sharma National Bureau of Agriculturally Important Microorganisms Indian Council of Agricultural Research Kushmaur Maunath Bhanjan 275103 India National Institute of Abiotic Stress Management Indian Council of Agricultural Research Baramati Pune 413115 India

Induced accumulation of polyphenolics and flavonoids in cyanobacterial strains grown under different salt concentrations is correlated with their growth under stress conditions and enhanced antioxidant activity. Plectonema boryanum, Hapalosiphon intricatus, Anabaena doliolum and Oscillatoria acuta grown for 21 days under different salt concentrations (80, 160, 240, 320 and 400 mM) in BG11 medium showed differential growth responses in terms of biomass, total protein, chlorophyll content, total content of polyphenol, flavonoid and carotenoid, accumulation of phenolic acids (gallic, caffeic, chlorogenic, ferullic and vanillic) and flavonoids (rutin and quercetin). Cyanobacterial extracts showed prominent free radical scavenging antioxidant activity (AOA) in terms of % DPPH discoloration. Highly significant (p < 0.05) and strong correlation was found between TPC and AOA (r = 0.974). Other positive but non-significant (p < 0.05) correlations were observed between AOA and gallic acid (r = 0.893) and AOA and caffeic acid (r = 0.931). Significant and strong correlation was also observed between gallic and caffeic acid (r = 0.973). Positive but lesser magnitude correlations were recorded between TPC and caffeic acid (r = 0.905), TPC and gallic acid (r = 0.920), gallic and vanillic acid (r = 0.916) and caffeic and vanillic acid (r = 0.814). An integrated combination of growth parameters, salt-induced accumulation of phenylpropanoids and stress-derived subsequent antioxidant property of cyanobacterial extracts is thought to provide evidence that secondary metabolic changes can act as the possible alternative mechanism to overcome stress-induced damages in cells.

Iron deficiency is the most common nutritional deficiency leading to anemia in pregnancy. Conventionally, non-heme form of iron salts has been the mainstay of treatment. However, patient compliance is an important concern with existing oral iron therapy due to gastrointestinal side effects. Heme iron, a better bioavailable and tolerable form of iron can be suitable form of iron for supplementation in pregnancy. Evidence suggests its utility in pregnancy for treatment of iron deficiency anemia with benefits extending to postpartum period. Effective transfer across placenta to fetus further supports its utility in pregnancy. This review discusses in details the absorption kinetics along with clinical evidence on efficacy, safety, and tolerability of heme-iron supplementation in iron deficiency anemia of pregnancy.
