Rapid mass propagation of endangered valuable medicinal plant Salacia chinensis L. and GC-MS/LC-MS analysis of active compounds produced in callus and leaf extracts

A protocol for indirect organogenesis of Salacia chinensis was established. Normally S. chinensis is propagated through seeds. However, due to the difficulty to obtain uniform plants in a short time period by seed germination, micro-propagation is a possible alternative method. For the micro-propagation, media with different concentration combinations of cytokinins and auxins were used to induce callus formation in three explants types: leaf segment, nodal segment and seeds. The rate of recurrence of callus formation from leaf on Murashige and Skoog (MS) basal medium supplemented with thidiazuron (TDZ) 0.5mg and TDZ 1mg was 100% and the maximum percentage of shoot let development from nodal segment on MS basal medium supplemented with BAP 6-(benzylamino purine) 3.5+ indole3-butyric acid (IBA) 1 mg/l was 78.3% when compared to other plant growth regulators (PGR) combinations used. The highest shoot regeneration response (85%) and the determined shoots (12.33 ± 0.33%) per callus were attained from leaf explants on MS medium containing 1-napthaleneacetic acid (NAA) 1mg/l + BAP 0.5 mg/l. The seeds showed highest percentage of shoot formation on MS medium supplemented with BAP 2mg + indole 3-acetic acid (IAA) 2mg/l and BAP 2mg + isopentenyl adenine (2iP) 2mg/l. Highest root formation (70±1.3%) was found in shoot regenerated using leaf segment on MS medium supplemented with IBA 0.5mg. The gas chromatography mass spectrometry (GC-MS) analysis of methanolic extract of callus showed more compounds at higher percentage. HPLC-MS analysis of methanolic extract of callus showed higher concentration of Mangifera than in leaf extracts are reported for the first time.
An Effective Practice of ICT Tools in Higher Education to Improve the Teaching Learning Process

Education is a process that simplifies learning. It should be a continuous process in one’s life to attain success. Over the decades, Information and Communication Technologies (ICT) have gradually begun to play a very important role in education, with their usage in education is growing worldwide continuously. These methods allow access to information through the internet. In education, ICT is the method of teaching that uses information and communication technology to support, improve and optimize the transfer of information, in turn leading to the invention of smart education. This improves the quality of teaching, the learning process of students and ultimately facilitates e-learning. It is commonly believed that technology can empower educators and students, making substantial contributions to knowledge and achievement. This paper gives an insight into the various tools that help instructors to develop online course content using Learning Management System tools. These tools allow the instructors to conduct online classes from any location using tutor tools and desktop recording tools to record screen output for further use. The instructor can assess the students in their course using assessment tools and can also enhance teaching methods using innovative teaching tools. The paper also throws limelight on the feedback taken by the faculty as well as the students about the usage of various tools in higher education which helps in analyzing the best suitable tools.
Differences of Athletes’ Blood Lactic Acid Levels Before and After 1500 M Run

The high intensity of training and competitions that athletes in various branches undergo exercise often carries a high risk of injury and fatigue. Efforts to recover from fatigue are required after athletes undergo training and competitions so that the athlete's body is back to normal. This study aimed to analyze the differences in blood lactic acid levels before and after the 1500 M run. This study used a quantitative method with a cross-sectional design. The research subjects were soccer athletes who were actively exercising. The variables to be studied were blood lactic acid levels and the identity data of the research subjects. This study included all soccer athletes in the FIK UNP Soccer Activity Unit, totaling 51 people. The sample is part of the population, namely 12 people taken purposively. The subject's identity data were collected using a questionnaire and data measurement of lactic acid levels using Accutrend Lactacid. Measurement of lactic acid levels was carried out before running 1500 meters and after resting for one hour. The results showed that the lactic acid levels after running the 1500 m run increased five times than the lactic acid levels before doing the 1500 m run. However, statistical analysis test results after measuring the lactic acid levels after an hour of rest, the lactic acid levels returned to normal conditions. The results of statistical tests showed that there were differences in blood lactic acid levels before and after running 1500 meters in athletes (α <0.05). Keyword: Lactic Acid Levels, Running 1500 m
Negotiating Political Power at ‘Critical Junctures’: Women and Constitution Drafting in South Africa and India

From a feminist institutionalist perspective, this article engages in a comparative analysis of South Africa, one of the only post-transition democracies where women organized as a distinct interest group representing gender interests were able to negotiate and gain access to political power, and India, where women’s participation was predominantly as ‘nationalist women’. It argues that constitution drafting is a decisive critical juncture when descriptive representation can be translated very effectively into the substantive representation of women as equal citizens, provided women qua women and as gender-conscious agents are able to intervene to promote the cause of their effective political participation.
Performance Allowance, Motivation, Employees’ Work Achievement And Organizational Performance Among Goverment Employees

This research analyzed the relationships among performance allowance, employee motivation, work achievement and organizational performance in the Ministry of Religion's Office Lumajang City. This research used a quantitative research design based on. Structural Equation Modeling (SEM) model. Research results showed insignificant direct between performance allowance and motivation, employees’ work achievement, and organizational performance. Work achievement has a direct and strongest significant influence on performance improvement in public organizations. Nonetheless, the influence of work achievement on organizational performance is mediated by a number of supporting factors, including performance allowance and motivation.
Trace Element Levels in the Serum of Hermann´s Tortoises (Testudo hermanni)

Up to now, blood reference values for trace elements (zinc, copper, iodine, iron, selenium and manganese) in the serum of Testudo spp. have not been established. Most studies concerning trace element levels in blood of reptile’s regard environmental pollution esp. concerning selenium. In the present study levels of iron, copper, iodine, zinc, selenium and manganese were evaluated in 130 blood samples of clinically healthy Hermann´s Tortoises (Testudo hermanni), originating from pet tortoises in Germany (n= 64), extensively kept captive-hatched tortoises from Turkey (n=20), and from free-ranging specimens of two locations in France (n=46). The French habitats differ in the nature of the soils, one being low in lime and another high in lime. The levels of trace elements in the blood were compared between the different groups and to the levels of trace elements in the respective feed rations resp. food plants. The aim was to check the correlation between origin, husbandry, feeding and sex on the levels of trace elements in the blood. Blood levels of trace elements, regardless of origin, gender, or diet, generally showed a wide range. Also there existed a poor correlation to contents in diet concerning iron, selenium, and manganese, but a statistically significant correlation to zinc, copper and iodine. Preliminary reference values of zinc, iodine and copper can be a useful tool to diagnose nutrient deficiencies, poisoning and deficiency symptoms in Testudo hermanni.
Estimating net ideal cycle time for body-in-white production lines

In the automotive industry, a Body in White (BIW) refers to the first step, the basic structure, in the production of a vehicle. Once a BIW production line has been built, the (maximum) capacity is fixed and throughput is therefore limited by the equipment specified during the design phase. The main metric used to inform the production line design is the Net Ideal Cycle Time (NICT). Unfortunately, the state of practice to estimate the NICT is a basic heuristic that does not account for production variation. In this paper, we challenge the current estimation approach by proposing an alternative that assumes actual production to follow a Weibull distribution. The proposed model is derived and estimated from empirical data. The results suggest that BIW production lines have traditionally been designed with too low a capacity, resulting in planned throughput rarely being achieved. On the other hand, increasing the design capacity implies a higher initial investment. In this paper it is demonstrated that the higher investment required is offset by reduced losses, resulting in more reliable planning and returns.

Predictions: Sociotechnical The Making of Crime Predictions: Sociotechnical Assemblages and the Controversies of Governing Future Crime

We are witnessing an upsurge in crime forecasting software, which supposedly draws predictive knowledge from data on past crime. Although prevention and anticipation are already embedded in the apparatuses of government, going beyond a mere abstract aspiration, the latest innovations hold out the promise of replacing police officers’ “gut feelings” and discretionary risk assessments with algorithmic-powered, quantified analyses of risk scores. While police departments and private companies praise such innovations for their cost-effective rationale, critics raise concerns regarding their potential for discriminating against poor, black, and migrant communities. In this article, I address such controversies by telling the story of the making of CrimeRadar, an app developed by a Rio de Janeiro-based think tank in partnership with private associates and local police authorities. Drawing mostly on Latour’s contributions to the emerging literature on security assemblages, I argue that we gain explanatory and critical leverage by looking into the mundane practices of making and unmaking sociotechnical arrangements. That is, I address the chain of translations through which crime data are collected, organized, and transformed into risk scores. In every step, new ways of seeing and presenting crime are produced, with a significant impact on how we experience and act upon (in)security.

The global epidemic trend analysis of influenza type B drug resistance sites from 2006 to 2018.

INTRODUCTION Influenza is a severe respiratory viral infection that causes significant morbidity and mortality, due to annual epidemics and unpredictable pandemics. With the extensive use of neuraminidase inhibitor (NAI) drugs, the influenza B virus has carried different drug-resistant mutations. Thus, this study aimed to analyze the prevalence of drug-resistant mutations of the influenza B virus. METHODOLOGY Near full-length sequences of the neuraminidase (NA) region of all influenza B viruses from January 1, 2006, to December 31, 2018, were downloaded from public databases GISAID and NCBI. Multiple sequence alignments were performed using Clustal Omega 1.2. 4 software. Subsequently, phylogenetic trees were constructed by FastTree 2.1. 11 and clustered by ClusterPickergui_1.2.3. JAR. Then, the major drug resistance sites and surrounding auxiliary sites were analyzed by Mega-X and Weblogo tools. RESULTS Among the amino acid sequences of NA from 2006 to 2018, only Clust04 in 2018 carried a D197N mutation of the NA active site, while other drug resistance sites were conserved without mutation. According to the Weblogo analysis, a large number of N198, S295, K373, and K375 mutations were found in the amino acid residues at the auxiliary sites surrounding D197, N294, and R374. CONCLUSIONS We found the D197N mutation in Clust04 of the 2018 influenza B virus, with a large number of N198, S295, K373, and K375 mutations in the helper sites around N197, N294, and R374 from 2006 to 2018. NA inhibitors are currently the only kind of specific antiviral agent for the influenza B virus, although these mutations cause mild NAIs resistance.
PARTICIPANTS' EXPECTATIONS AND LEARNING NEEDS IN AN ONLINE PROFESSIONAL DEVELOPMENT INITIATIVE CONCERNING “EMERGENCY REMOTE EDUCATION” DURING THE 2020 COVID-19 LOCKDOWN

During the lockdown due to the COVID-19 pandemic, several online initiatives have been enacted to provide teachers and educators with the skills needed to face the transition to online learning and teaching. Voluntary attendance of these kinds of initiatives for continuous professional development can be considered as a self-directed learning strategy enabling users to reduce a perceived skill gap. In this work, we explore and describe the expectations and the perceived learning needs of a group of participants who voluntarily decided to attend a webinar series concerning “Emergency Remote Education”, carried out by the European Distance E-learning Network (EDEN). The data collected through a short questionnaire, filled in by 607 participants, show that more than 50% of the respondents self-assessed their level of expertise as high. The results may provide insights into how to design online continuous professional development initiatives which are open to different targets.
The Utility of ‘Covid-19 Mobility Report’ and ‘Google Trend’ for Analysing Economic Activities

WHO urged the world population to practice social distancing to prevent transmission of the COVID-19. Social distancing leads the policy to limit mobility of people to work, school and other social activities. Restricting population mobility makes people start to look for other alternatives to do economic activities. The use of the internet is optimized in carrying out economic activities. This research aims to describe the economic activity using internet during COVID-19 pandemic. The research also aimed to show the relationship between the people mobility during COVID-19 with economic activity using internet. Descriptive analysis and inference analysis are applied to analyse the economic activities. Data source are provided by google trend and google COVID-19 community mobility report. Google trend data are used to represent the economic activities by deriving the queries of keywords related to economic activities. The People mobility to retail, grocery, parks, transit station, workplace and residential are obtained from Google COVID-19 mobility report. Data from COVID-19 mobility report treated as independent variables. As for dependent variables, data from google trend are applied with the keyword ‘jual’ and ‘beli’. Two multiple linear regression models are applied to show the relationship between independent variables and dependent variables. The result showed that mobility to workplace and residential are significantly affecting economic activity during pandemic time for both models
Design of a Laboratory Scale Solar Microgrid Cyber-Physical System for Education

Renewable energy sources such as solar and wind provide an effective solution for reducing dependency on conventional power generation and increasing the reliability and quality of power systems. Presented in this paper are design and implementation of a laboratory scale solar microgrid cyber-physical system (CPS) with wireless data monitoring as a teaching tool in the engineering technology curriculum. In the system, the solar panel, battery, charge controller, and loads form the physical layer, while the sensors, communication networks, supervisory control and data acquisition systems (SCADA) and control systems form the cyber layer. The physical layer was seamlessly integrated with the cyber layer consisting of control and communication. The objective was to create a robust CPS platform and to use the system to promote interest in and knowledge of renewable energy among university students. Experimental results showed that the maximum power point tracking (MPPT) charge controller provided the loads with power from the solar panel and used additional power to charge the rechargeable battery. Through the system, students learned and mastered key concepts and knowledge of multi-disciplinary areas including data sampling and acquisition, analog to digital conversion, solar power, battery charging, control, embedded systems and software programing. It is a valuable teaching resource for students to study renewable energy in CPS.
On the significance of weak hydrogen bonds in crystal packing: a large databank comparison of polymorphic structures

While there is general consensus on the fundamental role played by strong hydrogen bonds (HB) in crystal packing, the significance of weak CH⋯X (X = N, O, S, F, Cl) interactions is still debated. Here, ∼250 polymorph pairs of small molecules with no strong HB donors were retrieved from the Cambridge Structural Database. Statistical analysis tools were applied to look for conserved features among chemically analogous compounds in terms of crystal packing, self-recognition energetics and lattice cohesion. The occurring frequency of weak HB is significantly higher than that expected for a random distribution of close H⋯X contacts, but they are seldom conserved in different polymorphs and do not correlate with either the molecule–molecule or the lattice energies. Comparison of interaction energies of closest molecular pairs in the solid state shows that weak HB do not generally provide a significant thermodynamic drive toward crystallization. Accordingly, lattice energies of different polymorphs are often dominated by the dispersive/repulsive balance, pointing out the importance of steric and shape factors in determining their self-assembling. This likely indicates that, in most cases, the preference for a particular self-recognition mode arises due to the interaction of the whole charge density distributions, rather than to specific weakly attractive atom–atom contacts. Weak HB, however, might assist this process, providing extra stabilizing terms and advantaging some interaction modes over other ones. Implications on thermodynamics and kinetics of crystallization are discussed.
An update of aberrant methylation detection on circulating cell-free DNA as a tool to improve prostate cancer diagnosis and prognosis

Prostate cancer (PCa) remains a disease of high incidence, but orphan of a specific screening program. For this reason, non-invasive techniques capable to predict PCa in patients with high specificity and sensitivity are still an urgent need. One of the major goals is to improve the PCa diagnosis and the identification of patients who benefit from tissue biopsies. Another need is the necessity to have novel biomarkers to better stratify the risk of patients with PCa to predict the aggressiveness of the tumor and the overall survival. Liquid biopsy can be an important non-invasive tool to stratify PCa at the molecular level to improve diagnosis and prognosis, and, possibly, to develop screening programs and follow-up. With this review, we are reporting the lastest update of aberrant methylation detection on circulating tumor DNA as a tool to improve prostate cancer diagnosis and prognosis.
The Deployable Low‐Band Ionosphere and Transient Experiment

The Deployable Low‐Band Ionosphere and Transient Experiment (DLITE) is a four‐element interferometric radio telescope made from mostly commercial off‐the‐shelf parts to minimize costs and maximize ease of deployment. It operates in the high frequency and very high frequency (VHF) regimes, nominally in a 30–40 MHz band, but with good sensitivity (sky‐noise dominated) in the 20–80 MHz range. Its configuration is optimized to probe ionospheric structure using the so‐called “A‐Team,” exceptionally bright sources of cosmic radio emission. Methods have been developed to track the apparent positions and intensities of A‐Team sources without the need for beam forming to enable measurements of VHF scintillations as well as total electron content gradients. Time difference of arrival and frequency difference of arrival methods have been adapted for all‐sky imaging to facilitate both statistical measurements of scintillation levels and time domain astronomy. This study provides a detailed description of the system design, the analysis algorithms, and the science that can be conducted using results from two prototype DLITE systems in Maryland and New Mexico.
