Method of Elimination Inrush Current After Connection of High Input DC Voltage
Authors: Kellner Jakub , Prazenica Michal
Published: June 2020

This article deals with the problem of elimination inrush currents. The document proposes an active method for limiting the inrush currents during circuit switching when high inrush currents occur. The proposed system limits current in the circuit by means of a series connected Mosfet transistor. The Mosfet transistor is controlled in a linear resistive region. In the case of an inrush current in a circuit, the Mosfet transistor limits the magnitude of the current flowing into the circuit. The article also solves the problem of transistor power load. In the article there is a chapter that deals with the maximum magnitude of the limiting current that can flow through the transistor so as not to destroy it. In this new inrush current limiting configuration, the operator can directly define the amount of surge current that must not be exceeded after the circuit is closed. The proposed system is also complemented by other protective and control elements that are described in this article.

Brazil's China Challenge
Authors: Sucre Carlos
Published: June 2020

In 2001, Goldman Sachs named Brazil one of the four most important emerging economies, with China, Russia and India.1 The BRICs, a term coined by Jim O’Neill, are prophesized to become four of the top six economies in the world by 2050,2 and, with the United States, form a new core of power. O’Neill argued that if Brazil could, “keep inflation low and engage with the rest of the world, Brazil could immediately become something else.”3 In the past twenty years, Brazil has done that and more. It has established a vibrant democracy, controlled inflation and achieved solid growth.
DEVELOPMENT OF UNIFORM STRENGTH DESIGN OF CABLE-NET MID-WATER TRAWL
Authors: Rozenshtein Michael
Published: June 2020

The article implements the previously outlined proposal [1] on the feasibility of

calculating the diameters of cables and threads of the cable-net part of a mid-water

trawl based on ensuring their strength is equal to the cables in the first net piece.

The case study was carried out regarding a commonly used trawl “Atlantic-1920

m, Nizin” developed by the company “Fishering Service”.

The calculation algorithm is described which includes determination of resistance

forces of the cable-net part and tensions in the cables and threads of net pieces.

The safety factor is determined on the basis of the permissible stresses for the

respective materials of which cables and threads are manufactured.

After that, the values of diameters for cables and threads are calculated so as to ensure

that the safety factor in the net pieces is equal to the cables in the first net piece.

As a result, the formula is derived, which is able to calculate the diameters

of cables and threads of the cable-net part of a mid-water trawl based on

ensuring their strength is equal to the cables in the first net piece.

Ideology and Historical Concepts: the Evolution of Ideas about the Caucasian War in the XX – XXI Centuries
Authors: Nevskaja Tatˈjana Aleksandrovna , Kondrasheva Alla S.
Published: June 2020

In the article, the authors attempted to consider changes in the general concept of the Caucasian war during the 20th and beginning of the 21st centuries, depending on the political and ideological attitudes inherent in various historical stages. The key moments of this complex and ambiguous phenomenon are analyzed, which still cause heated discussions in science and society (name, dating, reasons, Caucasian muridism, problems of Muhajirism).It is indicated that historiography of the beginning of the twentieth century, as in the earlier period, did not dispute the legality of the establishment of Russian orders in the region. It is shown that in the Soviet period, the assessment of the movement of highlanders in the East and West Caucasus depended not only on a change in the historical paradigm, but also on a change in the general direction of state policy in the field of ideology (“national liberation struggle against tsarism”, “Shamil is a protege of Sultan Turkey and British colonialists","the struggle against the colonial policy of tsarism and against their own feudal lords"). Attention is drawn to the fact that the collapse of the USSR, the destruction of the Marxist concept of history, the development of national and separatist movements, the beginning of the Islamic revival in the North Caucasus contributed to the beginning of the active process of revising the assessments and events of the Caucasian War, which was the most striking event in the history of many peoples.The article concludes that, despite the abundance of work, scientists have not only yet to illuminate the little-studied aspects of the Caucasian war, but also to give an objective interpretation to many of its stages, based on scientific approaches, and not following political orders for the sake of one or another ideology.

Competition assessment in business negotiations under distorting market conditions
Authors: Peleckis Kęstutis , Peleckienė Valentina , Peyravi Bahman , Leonavičienė Edita
Published: June 2020

The competition assessment process provides an analytical framework for business negotiation entities to mitigate, or avoid potential competition problems. It helps to identify possible alternatives that may reduce, or eliminate potential harm to competition. Limiting the number of business negotiation enti-ties leads to the risk that market power will be created and competitive rivalry will be reduced. The aim of the article is to analyze the theory and practice of developing and implementing business negotiation strat-egies in a complex way, also to evaluate the level of competition in distorting market conditions. The ob-ject of the study is to strike a balance at the level of competition in business negotiations, under distorting market conditions. The scientific problem is that bargaining theory lacks tools to assess and balance the level of competition between participants in market conditions that distort competition.

Population genetics and diversity structure of an invasive earthworm in tropical and temperate pastures from Veracruz, Mexico
Authors: Ortíz-Gamino Diana , Gregorio Josefat , Cunha Luis , Martínez-Romero Esperanza , Fragoso Carlos , Ortíz-Ceballos Ángel I.
Published: June 2020

Pontoscolex corethrurus(Müller, 1857) is an invasive tropical earthworm, globally distributed. It reproduces through parthenogenesis, which theoretically results in low genetic diversity. The analysis of the population structure ofP. corethrurususing molecular markers may significantly contribute to understanding the ecology and reproductive system of this earthworm species. This work assessed the genetic diversity and population structure ofP. corethruruswith 34 polymorphic inter simple sequence repeat markers, covering four populations in tropical and temperate pastures from Veracruz State. Nuclear markers distinguished two genetic clusters, probably corresponding to two distinct genetic lineages. The number of clones detected in the AC population was lower than expected for a parthenogenetic species. Also, the apparent lack of differences in population structures related to the geographic region among the populations studied may indicate that human-mediated transference is prevalent in these areas. Still, most individuals apparently belong to lineage A, and only a few individuals seem to belong to the lineage B. Thus, the admixture signatures found among the four populations ofP. corethrurusmay have facilitated a successful invasion by directly increasing fitness. In summary, addressing the genetic variation ofP. corethruruswith ISSR markers was a suitable approach, as it evidenced the genetic diversity and relationships in the populations evaluated.

Published: June 2020

Bdelloid rotifers are a group of microscopic invertebrates known for their obligate parthenogenesis and exceptional resistance to extreme environments. Their diversity and distributions are poorly studied in Asia, especially in China. In order to better understand the species distribution and diversity of bdelloid rotifers in China, a scientific surveys of habitats was conducted with 61 samples (both terrestrial and aquatic habitats) from 11 provinces and regions of China, ranging from tropics to subtropics with a specific focus on poorly sampled areas (Oriental) during September 2017 to October 2018. A total of 59 morphospecies (including subspecies) were found, of which, thirty-nine morphospecies (including one genus) are new records for China, almost doubling the number of previous records. Four rare morphospecies (Adineta cf. acuticornis Haigh, A. beysunae Örstan, Habrotrocha ligula loxoglotta De Koning and H. serpens Donner) are depicted and redescribed, and an updated checklist of Chinese bdelloids with their location and ecological information is presented. This study provides new data from a large region of China, enriching the knowledge of bdelloid biodiversity, and their global biogeography.
A conservation checklist of the herpetofauna of Morelos, with comparisons with adjoining states
Authors: Lemos-Espinal Julio A. , Smith Geoffrey R.
Published: June 2020

Despite being one of the smallest states in Mexico, the high diversity of habitats in Morelos has led to the development of a rich biota made up of a mixture of species typical of the Neovolcanic Axis and the Sierra Madre del Sur. However, recent expansion of cities in Morelos is likely to have consequences for the state’s herpetofauna. Here a checklist of the amphibians and reptiles of Morelos is provided with a summary of their conservation status and overlap with its neighboring states. Morelos is home to 139 species of amphibians and reptiles representing 32 families and 75 genera. Twenty-six of the 38 species of amphibians and 70 of the 101 species of reptiles that inhabit Morelos are endemic to Mexico. Fourteen species of amphibians and reptiles from Morelos are IUCN listed (i.e., Vulnerable, Near Threatened, or Endangered), 22 are placed in a protected category by SEMARNAT, and 41 are categorized as high risk by the EVS. The Tropical Deciduous Forest vegetation type hosts the greatest number of amphibian and reptile species in Morelos (84 species). Morelos shares the largest proportion of its herpetofauna with the State of Mexico (79.3%), Puebla (77.0%), and Guerrero (74.8%).
Complete power cycle exhaust heat regeneration and second law logic
Authors: Van Den Einde David
Published: June 2020

It is demonstrated, given a sufficiently large positive excess enthalpy of solution reaction between a molecular solid solute and a low boiling point solvent, that the differential in excess enthalpies of solution between the reaction in the solvent's dense liquid and expanded supercritical
states will enable the solution, when used as the working fluid in a closed condensing power cycle, to attain complete exhaust heat regeneration. Xenon is used as the solvent to demonstrate the potential. Errors in 18th century logic that helped establish the second law are explained.

Teaching Data Analytics Using Natural Law as Integrative Framework
Authors: Maheshwari Anil K.
Published: June 2020

Teaching and learning the multidisciplinary field of data analytics requires comfort with multiple domains of knowledge, each with its own assumptions, concepts, and skills. Ideally, such teaching will use an overarching framework that transcends and includes all the reference fields. Natural law provides such an all-encompassing framework for a stress-free and sustainable path to continuous learning. Teaching from natural law helps enhance the student's capacity for comprehension and integration of diverse knowledge and skills. This chapter presents seven key natural law principles, along with examples of their applications in teaching data analytics. It also presents V-theory of transcendence as way to connect with natural law within one's own consciousness.
Innovation, Creativity, and Brain Integration
Authors: Travis Frederick
Published: June 2020

The heart of creative thinking is the incubation stage, in which ideas freely move on a subconscious level going beyond the limits of the problem space to create new solutions. The incubation stage might be fostered through meditation practices that lead to transcending, such as the Transcendental Meditation (TM) technique that cultures greater brain integration in which the brain functions more as a whole. Higher brain integration is seen during the TM session within a few weeks of practice, and after the TM session with regular practice over time. Higher brain integration is associated with higher creativity and greater success in life. Adding the experience of transcending to enhance incubation of creative ideas is innovation from the inside. Training in transcending could be part of forward-looking graduate programs to help their graduates thrive in an ever-changing workspace landscape, and could be a workplace skill to support better performance in many professions.

There was an outbreak of pneumonia in the month of December 2019 in Wuhan, China that spread with a rapid rate throughout the country and shook the world by spreading across the globe causing many deaths due. This disease is confirmed by means of molecular method as a novel coronavirus and was named as 2019 novel coronavirus (2019-nCoV) in its initial stage; however, on February 11, 2020, World Health Organization (WHO) renamed this disease COVID-19, which means corona virus disease. COVID-19 has impacted nearly the entire world, affecting more than 100 countries including India. The Coronavirus Study Group consisting of the International Committee on Taxonomy of Viruses renamed this virus, which was provisionally named 2019-nCoV, as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). This nomenclature is based on taxonomy, phylogeny, and established practice. As on March 2020, WHO has confirmed 692,575 number of cases of COVID-19 with 33,099 deaths, which are distributed across the globe: Western Pacific region with 103,775 confirmed cases with 3,649 deaths; European region with 392,757 number of confirmed cases with 23,962 deaths; South East Asia region with 4,084 confirmed cases with 158 deaths; Eastern Mediterranean region with 46,392 confirmed cases with 2,813 number of deaths; America region with 142,081 confirmed cases with 2,457 deaths; African region with 3,486 confirmed cases with 60 deaths. This paper focuses on these areas and regions and tries to find establish the relationship between numbers of deaths and number of cases with respect to the temperature. This paper takes the study of specific areas around the world and also the case study of India to study the effect of temperature on the rise of and death due to COVID-19 virus.
Copper Black Coatings for the Absorption of Solar Concentration With an APPJ SiO2 Super-Hydrophobic Protection
Authors: Bueno Jose de Jesus Perez , Rojas Esmeralda Reséndiz , Hernandez Jorge Morales , López Maria Luisa Mendoza , Esquivel Rufino Alberto Chávez
Published: June 2020

Solar thermal energy can be captured on absorbent surfaces, but coatings tend to deteriorate, due to changes in hue, thermal shocks, or detachment of all layers. There is a great challenge in reducing the deterioration because of environmental factors such as corrosion, impact, and dust control, among others. The absorbent coatings interact with the incident solar radiation transforming it as heat energy, and selectivity allows a low emissivity. In this work, a three-layer system on copper is proposed. An anodized CuO or black copper layer as an absorbent with high absorptance is proposed. A protective layer was added to extend the lifetime of use while preserving the functional characteristics of the absorbent black layer by using SiO2 deposited by atmospheric pressure plasma jet (APPJ) using hexamethyldisiloxane. A selective layer of aluminum was deposited by physical vapor deposition (PVD). Thermal shocks were applied by concentrated solar power with a Fresnel lens to represent sudden temperature changes in the radiation absorbent when the weather changes.

Published: June 2020

This study is to find out the challenges and prospects faced by female entrepreneurs within micro and small enterprises in the case of salon owners in Bahir Dar City administration. Although various empirical studies show most micro and small enterprises (MSEs) are operated by women, and face many challenges, this research is done concerning developed countries, and they have the problem of generalization. To this end, a qualitative research approach is pursued. The qualitative data is gathered through semi-structured interviews from beauty salon owner women. Consequently, the findings reveal that the major challenges that hinder the salon industry according to this research are classified as a problem in startup and the growth phase, which in turn affect the prospects of these enterprises in the future. To mitigate these challenges, banks should have a specific loan portfolio for women entrepreneurs in salon businesses and introduce more financial access for women.
Recognition and Protection of Women's Rights and Gender in FDRE Constitution and Other Laws of Ethiopia
Authors: Wondim Yetimwork Anteneh
Published: June 2020

Irrespective of their contribution, women in Ethiopia have been facing issues like violence, gender-based discrimination, access to education and training, lack of basic human rights protection, and others. Girls' enrollment in education at all levels is much lower than boys. Female education is hampered mainly by the sexual division of labor, which confines girls to household activities. In addition, women have been suffering from gender-based violence under the guise of tradition and culture but condoned by society. In response to these problems, the Government of Ethiopia adopted relevant instruments pertaining to gender including the Convention for the Elimination of All Forms of Discrimination Against Women (CEDAW), The Beijing Platform for Action, The Ethiopian Constitution, and various other policies and establishing the national machinery for addressing gender issues. However, several challenges still exist in the realization of women's rights. Therefore, all the respect and protection given for human rights should also be given to women because women's rights are human rights.
Characterization of Slate Powder Wastes from Minas Gerais - Brazil
Authors: Palhares Luciana Boaventura , dos Santos Claudio Gouvêa , Binda Felipe , Hunter Tim Nie
Published: June 2020

Research and development related to the processing of recycled materials has grown progressively in recent times, as scientists endeavour to integrate sustainability criteria, depletion of natural resources, reducing the energy of technological processes involving extraction and processing of raw materials, etc. When it comes to processing slate, industries have to pass over several steps ranging from the extraction of rock blocks until the final products consisting of plates, leaving behind a considerable amount of waste in the form of a mud composed mainly of water, lubricants and crushed rock. This waste with no defined destination accumulates in yards, reservoirs and streams, affecting the environment. Slate powder has great prospects for recovery, recycling and further applications once it has chemical composition and components similar to raw materials used in ceramic and building construction industries. Therefore, a complete characterization of this powder is important and here we present some results of XRD, SEM, EDS, G3 morphology and thermal analysis of slate powder samples from the southeastern state of Minas Gerais in Brazil.

Authors: Marras Graziella , Bortolussi Augusto , Siotto Giampaolo , Surraco Marco , Careddu Nicola
Published: June 2020

The purpose of this research is to show how to reduce the amount of landfilled marble waste/scraps by collecting and re-purposing the marble microfine sawdust, which is produced after the sawing and processing of carbonate dimension stones. Our ultimate goal is to identify alternative uses, rather than landfilling. The current solution so far preferred - landfill - does not fully meet sustainable development criteria. Our reduction strategy is based on a regulatory framework which identifies waste, by-product and end of waste status clearer. After a careful characterization, the marble sawdust can be reused and marketed for industrial applications, that employ micronized calcium carbonate, as a new material. During the first few years of study, the research focused on the construction industry (i.e. concrete – plaster - brick), by assessing the extensive use of marble sludge. The building industry is able to incorporate and reuse waste materials deriving from different industries, although, in this way, such material would be regarded as of poor quality. The current trend is to add high economic value to this waste. Since product specifications for calcium carbonate vary depending on its application, a comparison with the paper - rubber - and tyre calcium carbonate requirements is described herein and, in addition, the final results of the tests carried out on marble sawdust in tyre mixtures are also reported in detail.
From Thesis to Teaching: The Practice of Using Rocks in Architecture and the Challenge of "Making it Different"
Authors: Neves Risale
Published: June 2020

About 20 years ago, the lack of knowledge of the Brazilian architects about the use of rocks as natural materials was being commented which may have contributed to the problems of the stone coatings of buildings in several cities, compromising their original features and the beauty of many works. Professionals did not seek technological data on rocks and students were not instructed on such subjects in classrooms. The choice of these materials was supposedly empirical. Between 2010 and 2012 it was possible to obtain access to information about the contents of materials teaching in the architecture courses of Brazil, and also to inquire whether or not there was knowledge by architects active in the market on the subject, interviewing 64 professionals in 13 states from the country. The architects would be authors of architectural projects of large buildings and responsible for the materials specifications. Conclusion: there is no teaching directed to the use of rocks in Architecture in the country courses and architects never learned formally about such subject, fact that justified in a doctorate thesis proposal, the creation of the first discipline on the subject in the Course of Architecture and Urbanism of the Federal University of Pernambuco, UFPE, Brazil.
Stereotomic Design: The Use of Stone in Contemporary Architecture
Authors: Marzo Carla , Neves Risale
Published: June 2020

Stereotomy, as a constructive technique, has a millennial history that has been optimized over time due to the development of geometry and construction . Using mainly stones specially limestone the stereotomic design takes advantage of the subdivision of solid big structures into smaller different pieces, named ´voussoirs´. These pieces are limited in forms and they work through the assembly of multiple units to create the final structure. Precision in the cuts and the correct placement of each part is crucial to ensure static and structural safety. The development of digital technology which has been taking place through the last decades re-ignited the interest in the use of stones as an essential material to buildings structures. As a result, many experiences took place mixing the use of stones with computerized and manufactoring techniques that , in turn, boost the industry of stone cutting. This paper presents information on the use of stereotomic design through the centuries, focusing on its evolution as a technique and on the results that are showing out in contemporary architecture. Through an analysis of the recovery of stone as a constructive and structural material, it is the aim of this study to establish a general panorama on the results achieved in the field of architecture and design in order to understand the methodologies applied when using the stereotomic technique.

Introduction: Loss of memory is the hallmark of dementia. In Sri Lanka, validated tests are not available for assessment of memory. The objective of the project was to study performance of Sri Lankan older adults on three memory tests: Lankan Verbal Learning Test (LVLT), Benton Visual Retention Test (BVRT) and Modified Enhanced Cued Recall Test (MECRT). Methods: Participants were 241 healthy individuals aged between 50 to 80 years. They were individually administered the tests by a research assistant. The LVLT is a verbal list learning task. The BVRT contains geometric figures that are presented in the recognition memory format. The MECRT assesses the memory for pictures aided with semantic cues. Means of test scores were calculated and compared for gender, age and levels of education. Multiple linear regression models were used. Results: The mean age was 63 (SD=7.7) years. Gender effect was prominent on verbal memory scores. The test scores were influenced by gender and education level. Gender, age and education together explained 15.6% and 9.6% of the variance of verbal memory score and visual recognition memory score respectively. Variance of MECRT scores were minimally explained by demographic variables. Conclusion: MECRT is the least influenced by demographic factors and could be used for Sri Lankan older persons irrespective of their gender, age and education.

This Repository Information System is an idea that appears to help agencies manage thesis archiving that was previously still done conventionally by collecting the results of thesis binding (hardcopy) and CD containing thesis files along with the source code of the program that was made (softcopy) into a digital system new and modern. Repository Information System is a system that is expected to help the School of Information and Computer Management (STMIK) Shaykh Zainuddin NW Anjani to organize the archiving of thesis data that has been done by students to be neater, safer and easier to manage. The repository information system was developed using the waterfall software development process model and object oriented analysis modeling, then implemented using the Codeigniter programming language, one of the PHP frameworks. The result of this study is a website-based thesis repository system that can archive student thesis data and can also be used to search and display existing thesis data through the admin or user interface in this case students.

Based on police data quoted from one of the online news portal pages, there are 43,842 thousand criminal acts in the The Capital City of Jakarta. Of all these criminal cases burglary empty houses included in the top three acts of crime. Houses that are abandoned by their owners are often targeted by crime operations due to lack of close supervision and security support technology. The purpose of this study is to detect human motion which can later be used to prevent crime in the form of theft. Another purpose of this research is to find out how the method used works in identifying changes in the image of several consecutive frames. This research develops a motion detection system in humans on video using a Closed Circuit Television (CCTV) camera which is simulated using sample video. The motion detection process uses the Accumulative Differences Image (ADI) method and the human detection process uses the classification of Opencv, the Haar Cascade Classification. Which with this method compares more than two different frames and the classification parameters used are full-body, upper body and face. System testing is done using several video samples taken with the distance and height of the camera against different objects. The results obtained from testing using video samples show an accuracy rate of 95.23%.

Genus Culicoides spp. includes small insects 0.5-2 mm in length, usually grey or black and at first glance very similar to mosquitoes. They are strictly hematophagous, feeding by attacking hosts outdoors and indoors (although they are less susceptible to the stationing like Aedes mosquitoesdo). The sting is very painful at the injection site and often followed by hypersensibilisation with the consequent formation of allergic dermatitis. Inaddition, the insects carry and transmit a multitude of diseases, often of a zoonotic character, and therefore are of great epidemiological importance. In our country, continuous monitoring of Culicolides spp. has been carried out and seasonal dynamics of their appearance in the period 2015-2016 is presented in this article. During October 2015, the presence of Culicolides spp. was confirmed in 10.00% of samples; in November, their presence was not established, whereas in December, 2.35% of samples proved positive for the presence of Culicolides spp. During 2016, from January to March, no Culicolides spp. were found in any of the examined samples. During April, their prevalence was 9.63%, in May - 6.74%, in June - 3.70%, in July - 15.78%, in August - 18.07%, in September - 27.27%, and in October - 45.65%. In Serbia, the dominant Culicoides spp. species are Obsoletus complex and Pulicaris complex established in 57.21% and 33.37% of samples, respectively. Other species are present in lesser extent. In Obsoletus complex, the dominant species was Culicoides obsoletus/scoticus. The percentage of Culicoides obsoletus /scoticus males in samples was 25.52%. Non-pigmented (young) females were present in 66.06% of samples; females who took blood in 7.55% and 0.87% were gravid females. In Pulicaris complex, the dominant species was Culicoides pulicaris. Males of Culicoides pulicaris were found in 19.23% of samples, non-pigmented (young) females in 70.96%, females who took blood in 9.08% while 0.73% were gravid females.
