    in trees solar energy is used in the process of photosynthesis .In photosynthesis Green leaves of trees convert this solar energy into different forms of energies for the growth of tree. As the law states that energy can neither be created nor destroyed. Same thing is happen in trees. Solar energy is in the form of light rays which consists electrons .These electrons are used by the tree and provides them sufficient nutrients for the growth of tree. These electrons are cyclic electrons and provide energy to trees. These electrons are flow in trees and produced very small amount of electricity which lies in the range micro voltage. The amount of flow of electrons is different in different types of trees and environmental conditions. Flow of electrons at the night time slow as compare to day. In trees we are using only one electrode to generate electricity which also reduces the production cost of electricity, but in lemon and potatoes we are using two electrodes to generate electricity. We can also generated sufficient amount of electricity from trees by using custom made voltage booster by using nanotechnology

    Multi-Verse Optimization (MVO) is one of the newest meta-heuristic optimization algorithms which imitates the theory of Multi-Verse in Physics and resembles the interaction among the various universes. In problem domains like feature selection, the solutions are often constrained to the binary values viz. 0 and 1. With regard to this, in this paper, binary versions of MVO algorithm have been proposed with two prime aims: firstly, to remove redundant and irrelevant features from the dataset and secondly, to achieve better classification accuracy. The proposed binary versions use the concept of transformation functions for the mapping of a continuous version of the MVO algorithm to its binary versions. For carrying out the experiments, 21 diverse datasets have been used to compare the Binary MVO (BMVO) with some binary versions of existing metaheuristic algorithms. It has been observed that the proposed BMVO approaches have outperformed in terms of a number of features selected and the accuracy of the classification process

    448-457In rodent control exercise, after successful control with rodenticides, the surviving population often rebuild up themselves rapidly due to reduced competition and high rate of reproduction. In this context, here, we investigated the potential of papaya (Carica papaya L.) seed powder as a natural reproduction inhibitor for male lesser bandicoot rat, Bandicota bengalensis (Gray and Hardwicke) in reducing the post control population rebuild up rate. Exposure of male B.bengalensis to cereal based bait containing 2, 3 and 5% papaya seed powder for 15 and 30 days durations in bi-choicelaboratory feeding tests resulted in the ingestion of total 7.14-18.15 and 13.74-41.25 g/kg body wt. of the active ingredient,respectively. Breeding performance of treated rats was 33.33 and 16.67% after treatment with 5% papaya seed powder for15 and 30 days, respectively. Autopsy of rats immediately after treatment withdrawal revealed a significant decrease inweights of testis, cauda epididymis, seminal vesicles and prostate gland. Sperm motility, sperm viability and sperm countwere found reduced and sperm abnormality increased significantly in the cauda epididymal fluid of treated rats as comparedto untreated rats. The total proteins, 17β-HSD, 3β-HSD and testosterone levels were also found decreased in treated rats ascompared to untreated rats. All the changes observed in treated rats showed partial or no recovery after 30 days of treatmentwithdrawal. The study suggests the potential of papaya seed powder in regulating fertility of male B. bengalensis which maybe exploited as a component of integrated rodent pest management

    Background: The objective was to study and analyze maternal serum alpha-fetoprotein levels as a biomarker of placental adherence in low lying placenta. Methods: This was a prospective observational study analysing the conditions and the data of 80 cases with low lying placenta in a tertiary care hospital. The analysis was done for the association of MSAFP with MRI, perinatal and maternal outcome. Results: The level of MSAFP was found higher in 12 out of 13 cases (93.3%) of placenta previa with placental adherence. There was significant surgical intervention (80%) and increased maternal morbidity (68.8%) in the study group with placental adherence and raised MSAFP respectively. Conclusions: MSAFP is an important biomarker for prognostication of placental adherence in low lying placenta

    Introduction: Prevention is the most appropriate measure to control H1N1 flu pandemic and awareness of H1N1 flu is ranked very high in preventive measures. Keeping this in view, study was designed to assess the awareness level and to compare it among urban and rural participants. Aims and objectives: To assess the knowledge, attitude and practices regarding swine flu among adult population, to assess whether there is any difference among rural and urban population and to assess the response generated by the media coverage and the Government efforts.Methods: This cross-sectional study was done from April to July 2015 on 300 houses from the urban area and 150 houses from rural area, chosen from study population by random sampling. Mean and standard deviation for continuous variables and percentages for categorical were calculated. Results: 94% of urban and 91.3% of the rural participants had previously heard about swine flu, main source being TV. 46% of urban and 74% of rural participants had myth about spread of swine flu by eating pork. 41.3% of urban and 8.7% of rural population thought that government measures are sufficient for controlling swine flu. Conclusion: Knowledge regarding swine flu pandemic is good among study participants but role of health care providers is minimal and requires more dedicated effort. Lack of awareness among study population regarding some key focus areas like health promoting habits, vaccination and myths regarding the spread is of serious concern and needs to be addressed by the media, health workers and the Government effort

    Get PDF
    Objective: Optimization of conditions for cholesterol oxidase production by the microorganism isolated from urban compost and dairy soil samples.Methods: Isolates were obtained on the basis of their capability of growing on isolation medium A and B and their cholesterol oxidase (CHO) production was estimated. CHO production was optimized by the optimization of temperature, pH, carbon sources, and organic and inorganic nitrogen sources.Results: 3 isolates out of 22 were found to secrete extracellular CHO as detected by cholesterol oxidase indicator plate A and were designated as cholesterol oxidase producing isolate 1, 2 and 3 (COP 1, COP 2 and COP 3). Results showed that the strain COP 2 belonging to the genus Rhodococcus sp. based on morphological, cultural and biochemical characteristics recorded highest cholesterol oxidase activity. Optimum temperature and pH for CHO activity were found to be 35 °C and 7.5 respectively. Steroidal substrate cholesterol produced a significant increase in CHO level (0.502 IU/ml). Organic and inorganic nitrogen sources were supplemented in combinations leads to increase in CHO production as compared to individual components. (NH4)2HPO4 and yeast extract supported the highest enzyme production (0.574 IU/ml).Conclusion: The isolate COP 2 produced significant levels of cholesterol oxidase extracellularly in optimized medium as compared to cell bound CHO, and can be easily produced on an industrial scale.Â

    Mechanisms and consequences of regulating neurabin and spinophilin's interaction with the tumor suppressor protein p140CAP

    Indiana University-Purdue University Indianapolis (IUPUI)Glioblastoma is the most aggressive type of brain cancer with very poor prognosis. Due to the lack of understanding of underlying mechanisms, there are no anti-invasive clinical therapeutics available. SRC terminal kinase (SRC) is a tumorigenic protein that is highly expressed in glioblastoma samples. SRC inhibitor kinase 1 (SRCIN1), also known as p140Cap is a negative regulator of SRC. Silencing SRCIN1 results in increased tumor invasion. Our lab has discovered two novel scaffolding proteins Spinophilin (Spn) and neurabin (Nrb) that bind to SRCIN1. They may play a role in regulating SRCIN1 activity, as well as its downstream effects that ultimately decrease SRC’s tumorigenic activity. Spn and Nrb are two scaffolding proteins that are heavily expressed in the central nervous system. Spn knockout mice develop more tumors, indicating that Spn acts as a tumor suppressor protein, although the mechanisms of Spn’s anti-tumor properties are not well understood. Spn and Nrb are PP1 targeting proteins that target PP1 to other substrates, resulting in dephosphorylation and alteration of function. We found that PP1 increases Spn association with SRCIN1, but decreases Nrb association with SRCIN1, indicating that the two proteins might have opposite effects to balance the activity of p140Cap. We also found that cyclin-dependent kinase 5 (CDK5) phosphorylates and regulates the association of these scaffolding proteins with the tumor suppressor protein, p140Cap. Understanding these mechanisms provides insight into new therapeutic targets that may ultimately decrease SRC activity and its tumorigenic and invasive properties

    Impact of EHR Technology Implementation on Physicians\u27 Job Satisfaction

    Get PDF
    The concept of an electronic health record (EHR) has been the solicitous subject of researchers’ discussion in recent times. The impact that a successful implementation of EHRs can have on physicians cannot be overstated. Factors which are critical to successful implementation of EHR systems are commonly known as crucial technology implementation factors (CTIFs). The present study investigates the CTIFs of EHR systems and also their impact on physicians’ job satisfaction and characteristics in North Indian multispecialty hospitals. The questionnaire has been distributed to physicians of 12 hospitals that have been using EHR technology. It has been concluded that five CTIFs—organizational support, training, software attributes, acceptance to change, and computer knowledge—play a more important role than that played by other factors. The factors have not been considered separately on the basis of preimplementation scenario and postimplementation phase. The study attempts to analyze the impact of EHR systems on job operational performance of physicians
