Influence of constant lighting, melatonin and geldanamycin under mice testicle over 60 days

Melatonin (N-acetyl-5-methoxytryptamine) is a hormone secreted by the pineal gland. In men, melatonin affects reproductive regulation in three main ways. First, it regulates the secretion of GnRH and LH. Second, it regulates testosterone synthesis and testicular maturation. Third, as a potent deputare of free radical that is both lipophilic and hydrophilic. The mammalian testis is an organ susceptible to environmental and therapeutic toxic agents that compromise spermatogenesis, the present study aimed to analyse the influence of constant illumination, melatonin and geldanamycin under the testis of rats treated for 60 days. Males were randomly divided into 4 groups, each consisting of 5 animals, which are: Group I control rats (untreated); Group II rats subjected to constant illumination for 60 days; Group III rats subjected to constant illumination for 60 days and treated with melatonin for 60 days; Group IV rats subjected to constant illumination for 60 days, treated with melatonin and geldanamycin for 60 days. Exposure to constant illumination affects the development of germinal epithelium, as well as decreased weight of the testicles, Leydig, Sertoli, and testosterone cells. Melatonin and geldanamycin treatment have a protective effect against constant illumination, reducing testicular damage when taken together.

You Are (not) Who Your Peers Are: Identification of Potentially Excessive Permission Requests in Android Apps

Millions of Android applications are now deployed on billions of smartphones and tablet devices. An enormous amount of users' private data are being collected and made accessible to such apps. Extensive research efforts have been devoted to smartphone app security. In particular, the current practice of the app markets and app security scanners is to ensure that the requested permissions are consistent with the used permissions. On the other hand, mobile apps need to seek consent from users to approve various permissions to access user information. However, users often blindly accept permission requests and apps start to abuse this mechanism. For example, a flashlight app may obtain users' locations and send them out to the server. As long as a permission is requested by the app developer and approved by the users, the state-of-art detection mechanisms will treat it as benign. In this paper, we ask the question “are the permission requests really necessary? ” The question is difficult to answer because it is hard to autonomously “comprehend” whether a permission is needed for the functionality of the app. We take the first attempt to tackle this challenge by comparing an app's permission requests with its peer apps, i.e., apps with similar functionalities. An app that requests/uses significantly more permissions than its peers is considered potentially malicious that will require further investigation. With this idea, we design a statistical approach to identify potentially excessive permission requests and evaluate it with apps from Play Store. Experiment results and case studies show that the proposed mechanism could effectively identify highly suspicious apps, which request many permissions that are not relevant to their functionalities.
Determinants of Multidrug Resistance Tuberculosis: Systemic Review and Meta-analysis

Objective: The aim of this systemic review and meta-analysis was to determine demographic, behavioral and clinical risk factors for multiple drug-resistant 19 studies were included in the systemic review and meta-analysis. Materials and Methods: Search engines; PubMed/Medline, Web of Science, Scopus and Google scholar were used to search related literatures on MDR TB and selected determinates of MDRTB. All data were independently extracted. We used a random-effects model according to the DerSimonian and Laird method. Results: The risk of having MDR-TB in patients who have informal education was 0.67 times lower than that of patients who have formal education (RR=0.67; 95% CI, 0.46 to 0.96). The risk of having MDR-TB in patients who have Diabetes Mellitus was 1.33 times higher than that of patients who have no Diabetes Mellitus (RR of 1.33 and 95% CI, 1.01 to 1.77) Conclusion: This systemic review and meta-analysis indicated that the risk of having MDR-TB in patients who have informal education was 0.67 times lower than that of patients who have formal education and the risk of having MDR-TB in patients who have Diabetes Mellitus was 1.33 times higher than that of patients who have no Diabetes Mellitus. Our review did not show the presence of association between MDR TB and other selected variables gender, smoking and alcohol. We recommend interested researchers on MDR TB to do further research on patient’s educational level as a risk factor for MDR-TB in order to explain the variation in MDR TB among patients with formal education and patients with informal education
A review on underground mine ventilation system

FEBRUARY 2021 In the field of mines, there are dozens of methods concerned with the optimization of ventilation system in underground mines and how bad ventilation system is playing a major effect on miners and mine’s activities. The ventilation system is considered very important because it consumed high energy of mines of total power consumption. This paper is a review of previous studies, which have been done before on design of ventilation system and its optimization methods like, using of software tools to simulate the numerical equations based on the pressure, temperature, flow rate, and other effected parameters, which are recorded by various ways of surveying. It has observed that Ventsim software is widely used because of its flexibility in dynamic simulation based on various parameters included deep, fan position and flow rate.
CONFINEMENT AND EQUILIBRIUM WITH INTERNAL ISLANDS IN A CONFIGURATION SCAN WITH RESPECT TO IOTA IN W7-X

A dedicated scan of magnetic configurations in Wendelstein 7-X has been performed with respect to the rotational transform ι to investigate the confinement properties in configurations located between the major resonances providing boundary islands for proper island divertor operation. The scan investigated configurations between the so-called high-iota configuration with the 5/4-islands at the boundary and the so-called standard configuration with the 5/5-islands at the boundary. In particular, when the vacuum-ι of the configuration is reduced starting from high-iota, the resonance ι=1 appears at the plasma centre and moves outward (as 5/5-island chain in the confinement region) due to the positive shear (in the stellarator sense, dι/dr>0) of the vacuum ι-profiles in W7-X. For the main part of the scan, the 5/5-island chain was located in the outer third of the plasma with respect to the minor radius. The experimental conditions had been chosen at a lineintegrated density of 3.5·10m and an ECRH power of 2MW (140GHz, X2). The paper summarizes the main observations that the plasma energy measured by the diamagnetic coils increases with decreasing vacuumι while the observed MHDactivity, which is connected to the outward moving 5/5-islands, increases in strength. The increase in plasma energy is attributed to an increase in confinement since it persists even if one accounts for volume changes due to the changes in configurations. The paper also presents MHD-equilibrium calculations using the HINT-code, which can treat islands in the confinement region properly, and compares them with the results of the VMEC-code which by itself cannot treat this situation since it is based on the assumption of nested flux surfaces. However, in combination with the EXTENDER-code, an approximation of the equilibrium field with islands can be provided. The differences in the results of these approaches are discussed.
Paper ID ICLASS06-103 APPLICATION OF THE DIRECT QUADRATURE METHOD OF MOMENTS TO Y-JET WATER SPRAYS

The recently formulated direct quadrature method of moments (DQMOM) is implemented in an Eulerian multi-fluid CFD code (Fluent 6.2) to simulate the droplet size distribution (DSD) in Y-jet water sprays. The essential idea behind the modeling approach is to solve continuum Eulerian equations for the gas phase and N droplet phases. Each droplet phase is characterized by a volume fraction and a diameter. The rate of breakup and coalescence determines the source terms of the transport equations of the N volume fractions and N diameters. These source terms are defined through a linear system involving the first 2N integer moments of the DSD. In this paper, two-dimensional axisymmetric computations of the atomization process of Y-jet water sprays are presented. For verification of the computations, phase Doppler anemometer (PDA) measurements have been conducted for several atomizing air ratios. The model is qualitatively assessed by examining the predicted spray characteristics such as droplet velocities and droplet sizes and their distribution, and the dependence on parametric changes.
Analysis of spatio-temporal patterns of Covid-19 virus pandemic and its hazards in Iran

The spread of the corona virus is one of the most important challenges in the world today, and the epidemic of this virus has affected all sections of society, including universities. As with any challenge, the coronavirus epidemic has posed many threats and opportunities for universities and the academic community. This crisis has led the scientific community to gain valuable experience in electeronic learning and be ready to enter a new era of teaching in new ways, including learning in three-dimensional spaces. Culture and art are also linked to education, and this can be the beginning of a move towards global integration in the education process. In recent months, many conferences have also been held virtually, which have been widely welcomed. Global policies have also taken measures to increase the budget for applied sciences so that, the National Science Foundation's budget is shifting from $ 8 billion a year to $ 40 billion. On the other hand, the Covid-19 epidemic has attracted the attention of researchers in various fields and it has changed the direction of world-wide research towards the basic sciences and finding solutions to treat this virus. This will pose a budget problem for some other research areas. Many universities around the world have also faced a number of problems due to the cyberspace approach, including declining enrollment of international students and lack of funding, and this has threatened the lives of some universities. Now, more than eight months after the onset of the coronavirus epidemic, universities around the world have made valuable arrangements to maintain and enhance their educational goals and to adapt more and more to this global crisis. Given the above, in this article we look at these valuable approaches globally. It is hoped that by taking advantage of scientific participation and transferring useful experiences at the global level, we can turn this threat into an opportunity to improve and enhance the level of science and awareness in the country.

Analysis of Solar and Wind-Based Hybrid Power Plant Using HOMER Software (Case Study: EMAS BAYU Hybrid Power Plant in Bondan, Cilacap)

Solar energy is an energy source that is widely used because it is free energy, eco-friendly and very abundant, especially in tropical countries. However, the energy obtained from solar energy is inconsistent and is heavily influenced by environmental factors. Recently, many researchers have developed hybrid power plants which combine two or more different energy sources in the same system. In this research, we develop a hybrid power plant with an off-grid system (not connected to the national electricity company) that utilizes solar and wind energy. The hybrid power plant being developed is installed in Bondan hamlet, Kampung Laut District, Cilacap Regency. The installed power plant is determined for its performance by analyzing several parameters such as total energy production, net present cost (NPC) and cost of energy (COE). These parameters are analyzed using software which called hybrid optimization of multiple energy resources (HOMER). The simulation results show that the total energy generated from photovoltaics (PV) is 5.8 times higher than that of the wind turbine, with details being 10,480 kWh/year from PV and 1,805 kWh/year from the wind turbine. For the COE and NPC values are Rp. 14,266/kWh and Rp. 1,190,000,000, respectively.
Fostering Public Army Relation in Nepal

Nepal maintained army strength even during the reigns of Lichchavi kings. Later, its operations began to generate income. The way in which King Prithvi Narayan Shah and his successors diligently mastered the art of warfare and strategy resulted in the success of the Gorkhali army. After the Kot Prava, the Rana family emerged and radically changed policies. This research studies on Nepali Army’s glorious history, transformation, and mainly its public relation. The Postmodern Military Model (PMMM) is the theoretical perspective that has guided this study. For this, a qualitative method that deals with subjectivity is adopted. Secondary data such as journals, books and standard websites are used to analyze the data. Nepali Army is not a threat to the society that it protects as it has been trying to build its trust and credibility among the public. During its Imperial Era, the Great Britain awarded several Grukha soldiers in its military the ‘Victoria Cross’ for their unparalleled bravery and courage in various battles. Nepali Army gets exposure to serve in the outside world for decades. Relation between civil and army has not been bad in Nepal for many centuries despite of having some rubbings in the modern Nepal. However, politicians, notably the sitting PM or Defense Minister, routinely try to invoke the Nepal Army and draw it into the political jurisdiction. Nepali Army has been doing its duties honestly and unfailingly both inside and outside Nepal.
Large magnetic fields and direct electric energy after P+B11 nuclear fusion measured at the Pulsotron-3 reactor

In this article, an efficiency of a group of Energy Recovery Coils (ERC), which were mounted in the Z-pinch type fusion device is described and the measured results of two tests T3073 and T3074 performed in 28 August, 2020 are presented in this paper. Tests were conducted by the Spanish Startup Advanced Ignition SL that operates the Z-pinch nuclear fusion reactor Pulsotron-3 loaded with Hydrogen-Boron (H+B11) thermonuclear fuel. The ERC were used to recover the electric energy directly from the plasma for the first time in the world and ERCs storing the energy in several large capacitors. During the test T3073 and T3074 the energy recovery capacitors recovered 22.59% and 17.74% of the injected energy at the target. Furthermore, a MAG-4 sensor measured the confinement time and the extremely large magnetic fields that were generated during the experiments. Experiments with the nuclear fuel generate magnetic field of more than 4 megateslas. Comparing to the experiments to the experiments with a dummy load (just hydrogen, but no boron), the peak magnetic field was 20-34 times larger and the stabilised magnetic field was 12-18 times larger. Thus, nuclear fusion generates large magnetic fields. In the proposed Pulsotron-3 technology thermonuclear fuel is utilised to generate clean electric power without CO 2 footprint and with reduced electricity cost. This industrial approach is a promising solution that can reduce world emissions to zero in less than 8 years.
SANI et al: MODELLING AND ANALYSIS OF PHOTOVOLTAIC SYSTEM UNDER PARTIALLY SHADED

*Corresponding author: sanisaidudandaura@gmail.com doi: http://dx.doi. org/10.4314/njtd.v17i4. 4 ABSTRACT: With the increasing penetration of solar electricity in residential, institutional and commercial centres around the globe, the phenomenon of partial shading (PS) in Photovoltaic (PV) power generation is gaining attention. Under Partial shading condition (PSC), cells that are shaded tends to have an equivalent current with cells that are unshaded in series-connection, due to this, the shaded cells operates in reverse bias and consequently becomes load and consumes the generated power. This causes a serious problem known as hotspot. This is characterized by the presence of excessive heat which consequently reduces the total generated power. Recently, researchers use the technique of bypass diodes across the PV cells so that the problem of partial shading can be reduced, but this solution taken alone, has made the nonlinearity and complexity of the system to increase. The shaded cells generate multiple peaks with only one global peak. Conventional Maximum Power Point Tracking (MPPT) algorithms do not differentiates the global peak from local peaks which may end up tracking local peak as global peak, this results in serious power loss. This paper seeks to solve this problem by modelling a PV system under PSC and through the application of Improved Harmony Search algorithm (IHSA) and variable step Perturb & Observe (P&O) to track the global peak instead of local peaks. Simulation was done in MATLAB/Simulink 2018a environment, and the results under standard test condition (STC) and PSC showed that the proposed IHSA had an improvement of 25%, 3.17% and 2.27%, 3.07% and 2.21%, 3.26% and 2.26% when compared with the improved particle swarm optimization (IPSO) under STC and PSC conditions respectively, which had a better advantage of minimizing power oscillation and improving the efficiency of the system, improved MPPT tracking, reduced error and a better tracking efficiency in both conditions.
Aggregating Local Metrics for Global Trust Calculations in the TOR Network

This paper discusses the design and implementation of a distributed trust calculation mechanism that allows users in the peer-to-peer TOR anonymity network to determine whether or not the nodes that comprise the TOR network are malicious. This is done through a cooperative algorithm that allows individual nodes to measure the trust of the TOR nodes they communicate with. The paper measures the performance of this algorithm and shows that the algorithm can accurately identify several kinds of malicious nodes in the TOR network. This paper will focus on the following security issues: the problem of self reported bandwidth and uptime that can lead to low resource attack, geographical location and Denial of service (DoS) attack and how to aggregate all these criteria in one value that indicate whether or not the onion router is malicious. The aggregation is performed using two different techniques, each of which uses the exact same aggregation methods except for geographical location. The first method, which excludes entire geographical locations, produced slightly worse results than the second method, which assigned a scale between 0 and 0.99 for each geographical location to signify its trust
