Modeling Study and Performance Investigation of a Thermoelectric Refrigerator
Authors: KEPEKÇİ Haydar , KOSA Ergin , EZGİ Cüneyt
Published: August 2021

Thermoelectric refrigerators are widely used in electronics, medical, and food industry application areas. A refrigeration effect can also be achieved without using any moving parts by merely passing a small current through a closed circuit made up of two dissimilar materials. This effect is called the Peltier effect, and a refrigerator that works on this principle is called a thermoelectric refrigerator. They consist of several thermoelectric legs sandwiched between two thermally conductive plates, one cold and one hot. Thermoelectric refrigerators presently cannot compete with the vapor-compression refrigeration system because of their low- coefficient of performance (COP). However, some applications have been preferred because of their small size, simplicity, quietness, and reliability. In this study, a thermoelectric cooler having a maximum cooling power of 50 W, having a dimension of 40mmx40mmx3.6 mm, is modeled in multi-physics software. Also, the performance of a thermoelectric refrigerator is investigated. It is computed the temperature difference between ceramics plates versus electric current and COP for a temperature difference between ceramics plates. The simulation results are compared with experimental data. The data obtained from the analyses have been compared with the experimental results and found to agree with each other. For the surface temperatures of 25 oC and 50 oC, the maximum coefficients of performance have been computed to be 1.091 and 1.445, respectively. In general, as the temperature of hot surfaces has increased for the same temperature differences, the COP of the thermoelectric cooler has increased.

Resumo

Estamos em um momento social e político onde a pauta inclusão escolar de alunos com necessidades educacionais especiais na rede regular de ensino esta sendo debatido de forma ativa, devendo a mesma ser uma ação prática e um direito garantido. A lei é clara quanto à obrigatoriedade da matrícula independente de sua deficiência e a garantia de sala de recurso multifuncional (SRM) para o desenvolvimento do atendimento educacional especializado (AEE), garantindo currículo, método, técnicas, recursos educacionais e organização específica para as pessoas com deficiência. Devido às políticas publicas alguns pais ficam receosos em matricular seus filhos em uma escola regular ou específica, pois, em sua maioria as escolas amazônicas não possuem condições efetivas de aprendizagem e desenvolvimento para as pessoas com deficiência. Nesta perspectiva, conduzimos o leitor a refletir qual seria a escola adequada para a inserção de alunos com deficiência? De forma a torná-lo independente e participante de um grupo social que possa assim desenvolver suas habilidades no processo de ensino-aprendizagem.

 

ABSTRACT

We are in a social and political moment where the issue of school inclusion for students with special educational needs in the regular education system is being actively discussed, and it should be a practical action and a guaranteed right. The law is clear as to the mandatory enrollment regardless of disability and the guarantee of a multipurpose resource room (SRM) for the development of specialized educational services (AEE), ensuring curriculum, method, techniques, educational resources and specific organization for people with disabilities. Due to public policies, some parents are afraid to enroll their children in a regular or specific school, because, most of the Amazon schools do not have effective learning and development conditions for people with disabilities. From this perspective, we lead the reader to reflect on what would be the appropriate school for the insertion of students with disabilities? In order to make them independent and participate in a social group that can thus develop their abilities in the teaching-learning process.

Document file is a means of transforming information from one person to another or from a group to another. The development of computerized technology has greatly increased. Document files are very vulnerable to fraud, eavesdropping or data theft by irresponsible parties. In order to maintain the security of document files, this can be done by using cryptographic techniques. Cryptography is the science of keeping data secure. Cryptography is one of the data security methods that can be used to maintain data authenticity, data confidentiality, and the authenticity of data transmission. SHA, which stands for Secure Hash Algorithm, is a standard hash function published by NIST (National Institute of Standards and Technology), (NIST, 1995a). This study will use the SHA-1 method to secure the authenticity of document files, document confidentiality, document integrity, and document authentication. This study describes the security process for detecting the authenticity of document files using the SHA-1 method in the form of detection so that confidential documents sent via public telecommunications cannot be changed or modified by unauthorized persons or unauthorized persons. This is done as an effort to minimize acts of fraud, hoaxes, or misuse of document files.

Baitul Maal wa Tamwil (BMT) is an institution that supports the economic activities of low-income communities based on the Islamic sharia economic system. KSPPS BMT KUBE SEJAHTERA 068 Sampit was formed on January 12, 2006 with the legal entity Cooperative No. 07/Kep-BH/DK.PM/VIII/2006, and is a Sharia Savings and Loans Cooperative (KSPPS) which has approximately ten years of experience serving and partnering with the community. At KSPPS BMT-Sampit there is still no auditing system to monitor whether the existing technology is running well and efficiently, as well as to provide an assessment of the maturity level of information system technology, therefore the author uses the Cobit 5 framework for the audit system by focusing on 2 domains that the choices are DSS01 (manage operation) and DSS05 (manage security service) based on the results of calculations that have been done, the maturity level of information technology in KSPPS BMT-Sampit is at level 4 (Predictable processes) for DSS01, and based on level 4 (Predictable Processes) for DSS05
Music listening to decrease intensity of agitated behaviour after severe acquired brain injury: An experimental multi-case study
Authors: Aadal Lena , Hald Søren Vester , Setterberg Ulla Johanna , Bonde Lars Ole
Published: August 2021

Agitated behavior following a traumatic brain injury is frequent, placing patients and staff at risk of injury. Such behaviors decrease rehabilitation outcomes. This case study explores staff-administered listening to preferred music as an intervention to reduce agitated behavior during sub-acute rehabilitation. The study included seven patients (6♂/1♀, aged 21-74 years) with agitated behaviour and suffering from severe acquired brain injury of different aetiologies. The intervention included 15 minutes of preferred music from a customized playlist created in collaboration between a relative, a music therapist and the staff at the rehabilitation clinic. Agitated Behavior Scale (ABS)-scores, blood pressure and heart rate measurements were obtained pre and post interventions. Two tailed t-test and visual analyses were conducted. Results suggest that listening to personalized playlists of preferred music with a supportive intensity profile may reduce the intensity of agitated behavior following an acquired brain injury in the sub-acute phase. Furthermore, the music listening intervention may have contributed to reduced pulse. Due to the small sample size and few measurements, further research to support the hypothesis is recommended. However, since music listening is an easily administered low-cost intervention with no obvious side-effects, it can be considered as a supplement to usual treatment.  Keywords: Acquired brain injury, neuro-rehabilitation, agitated behaviour,                    music therapy, non-pharmaceutical

Published: August 2021

Hypothyroidism can cause significant reproductive morbidity and its association with ovarian cyst formation is rare and when it occurs in children, it is referred to as Van Wyk and Grumbach syndrome. An 18-year-old girl was referred to our emergency services with suspicion of torsion ovarian cyst with USG findings as she had pain abdomen and vomiting of 3 days duration. She was provisionally prepared for laparoscopic surgery but on revaluation by USG bilateral thecaleutein cysts measuring 7x6.8x3.5 cms (right) and 10x6.8 x3.2 cms (left) were diagnosed. Her TSH level was 483 mI U/L . On probing she revealed past history of diagnosis of hypothyroidism and discontinuation of thyroxin therapy after taking for 6 months. Her anti TPO antibodies were >1300 IU/mL. USG thyroid revealed features suggestive of Hashimoto’s thyroiditis. She was counselled and started on thyroxin therapy with a dose of 4µg/kg and after 2 months of follow up the ovarian cysts have regressed and ovaries appeared normal on USG.

Performances of Photovoltaic System Using Grid Tied Transformerless Inverter
Authors: Raut Ashish , Tibude Sneha
Published: August 2021

In order to eliminate the common-mode (CM) leakage current in the transformer less photovoltaic (PV) systems, the concept of the virtual dc bus is proposed in this paper. By connecting the grid neutral line directly to the negative pole of the dc bus, the stray capacitance between the PV panels and the ground is bypassed. As a result, the CM ground leakage current can be suppressed completely. Meanwhile, the virtual dc bus is created to provide the negative voltage level for the negative ac grid current generation. Consequently, the required dc bus voltage is still the same as that of the full-bridge inverter. Based on this concept, a novel transformer less inverter topology is derived, in which the virtual dc bus is realized with the switched capacitor technology. It consists of only five power switches, two capacitors, and a single filter inductor. Therefore, the power electronics cost can be curtailed. This advanced topology can be modulated with the unipolar sinusoidal pulse width modulation (SPWM) and the double frequency SPWM to reduce the output current ripple. As a result, a smaller filter inductor can be used to reduce the size and magnetic losses.

História Global e a Cooperação Sul-Sul: uma agenda de pesquisa
Authors: Rizzo Aline Duarte da Graça
Published: August 2021

A História Global é uma abordagem que nasce da necessidade de compreender o mundo em franco processo de globalização marcadamente na virada do século XX para o XXI e apresenta uma proposta que visa combater dois principais problemas centrais recorrentes na historiografia moderna: o estadocentrismo e o eurocentrismo. Fenômenos transfronteiriços como os grandes fluxos migratórios e internacionalização da produção industrial, dentre outros, exigem um exercício de pensar os processos históricos para além da figura do estado nacional weberiano bem como compreender o cenário internacional contemporâneo onde a predominância europeia na economia, política ou cultura, é altamente questionada. Este trabalho propõe uma aproximação da História Global à disciplina das Relações Internacionais para a análise de um dos fenômenos globais mais relevantes do século XXI: a cooperação Sul-Sul. Para tal, a tipologia dos 4Cs (Contextualizar, Conceitualizar, Comparar e Conectar) elaborada por Diego Olstein (2015) é aqui proposta como um a caminho possível para pensar a cooperação Sul-Sul a partir da História Global.

Published: August 2021

O estudo objetivou investigar a estrutura interna de duas escalas de atitude parental, originalmente produzidas em língua inglesa e então adequadas ao contexto brasileiro. Da aplicação de questionários online com 105 genitores, propriedades psicométricas dos instrumentos foram investigadas pela análise de consistência interna, de componentes principais e estudo relacional entre as variáveis atitudinais. Na Atitude Parental para com a Natureza, os itens agruparam-se em adesão estética, oportunidades de contato e transformação positiva e, na Atitude Parental para com a Criança na Natureza, em benefícios ao desenvolvimento, riscos à segurança e repercussões desfavoráveis. Os Coeficientes Alfa de Cronbach mostraram-se satisfatórios e, apesar de tipicamente positiva, a atitude parental foi desfavorecida pela percepção de riscos à segurança da criança.

The transcription factor HNF4a: A Key player in haematological disorders
Authors: Belali Tareg , Abomughaid Mosleh , alhujaily Muhanad
Published: August 2021

Abstract

HNF4a is one of the steroid hormone receptor family of transcription factors with roles in the development of the liver and the regulation of several critical metabolic pathways such as glycolysis, drug metabolism, apolipoproteins, and blood coagulation. HNF4a transcriptional potency is well known due to its involvement in diabetes and other metabolic diseases. However, recently HNF4a has become highly associated with several haematological disorders, mainly because of genetic mutations, drugs and hepatic disorders. We review HNF4a structure and function, and its role in haematological disorders. We discuss possible novel therapies that are based on targeting HNF4a. There is no doubt that HNF4a based prognostic markers and therapeutic interventions will offer new opportunities in the clinical interventions of haematological disorders.
Icon “The Mother of God Tikhvinskaya With the Tale of its Image” From the Сollection of the Historical Museum
Authors: Tarasenko Lyudmila  Petrovna
Published: August 2021

The article is dedicated to the icon “The Mother of God Tikhvinskaya with the Tale of its Image” of the last quarter of the 17th century from the collection of the Historical Museum. It discusses its history, clarifies the literary source, as well as presents the analysis of the iconographic program, compositional features and artistic uniqueness. The work ended up in the museum collection due to global changes in post-revolutionary Russia, which triggered a large-scale movement of cultural properties. The icon originates from the Tikhvin Lands and belongs to the poorly studied culture of the Russian province. Recent research has unveiled a whole set of works linked to the icon painters of the Tikhvin Posad. The icon “The Mother of God Tikhvinskaya with the Tale of its Image” represents a vivid example of the art of Tikhvin masters of the second half of the 17th century.
Alexander Samokhvalov's picture frames : tradition and innovation
Authors: Lysenko Oksana Aleksandrovna
Published: August 2021

In recent years, two contradictory trends related to the study and display of picture frames have emerged in Russian museums. On the one hand, these works have at last caught the attention of scholars leading to publications on the evolution of art framing in Russia. However, the framing of paintings in museums is still not carried out on the basis of conducted research. In the light of a rapidly developing frame market, art historians and art critics have been increasingly replacing historical frames with massproduced ones, while disregarding historical reliability and authenticity of the frames, or the need to follow the author’s conception. Meanwhile, it is known that artists of different eras, as a rule, paid great attention to the selection of picture frames, with some among them, like A. N. Samokhvalov, creating their own. Thus, the purpose of the article is to examine the frames made by Samokhvalov, as well as to draw attention to the question of the author’s original picture framing. Samokhvalov’s frames are characterized by their unique design, which greatly affects the perception of the painting. Despite the fact that there exists a considerable body of art historical studies dedicated to the artist’s work, none of the researchers took notice of the problem of the picture framing. The article is the first to provide a scholarly introduction of designs and drawings of Samokhvalov’s frames, as well as works of art created on their basis. The artist’s frames from the collections of various museums have been attributed according to a comparative analysis. Likewise, traditional and innovative features in the works of Samokhvalov have been revealed as a result of stylistic assessment and comparison of frames produced by the artist with picture frames of the 17th – 20th centuries. The article illuminates the unexplored facet of the artist’s work presenting it in a new light. The research will not only allow to further preserve the unique frames of Samokhvalov in Russian museums, but also exhibit his works in accordance with the author’s intention.

El problema de la vivienda y los requisitos técnicos de construcción en El Salvador
Authors: Castellanos A. Ricardo
Published: August 2021

La vulnerabilidad de las construcciones de viviendas se ha puesto de manifiesto con los dos terremotos ocurridos a principios de este año, y ha sido más evidente en aquellas en donde vive el 50 por ciento de la población pobre del país. Si bien es cierto que la normativa de construcción ha mejorado, aún es necesario revisarla y mejorarla, pero sobre todo divulgarla y lograr su obligatoriedad y efectivo cumplimiento. Las fallas y los colapsos estructurales observados después de los terremotos fueron causados por defectos constructivos y de diseño, debidos a prácticas empíricas, sin asesoría técnica, sin control de calidad; o por ubicaciones de alto riesgo. El autor de este artículo presenta un bosquejo de los requisitos técnicos existentes en la actualidad, enmarcado dentro de la telaraña de leyes e instituciones relacionadas con la construcción.

Derecho a la información y rendimiento de cuentas en Centroamérica
Authors: Peraza Torres Delmy Xiomara
Published: August 2021

Este artículo presenta un análisis comparativo sobre las políticas informativas de Cosca Rica, El Salvador, Guatemala, Honduras y Nicaragua. Para ello, el estudio se enfocó en las oficinas de prensa de cada gobierno y en los criterios en que se basan para divulgar o no determinada información. Asimismo se ponen de manifiesto los problemas a los que se enfrentan los periodistas en cuanto al acceso a información específica y, por ende, la dificultad de los medios de comunicación en la fiscalización de los gobiernos, lo cual refleja, a todas luces, que la rendición de cuentas es incipiente en nuestras sociedades.

An investigation of the antioxidant properties of some culinary herbs and their potential application in a cosmetic preparation
Authors:   , Naidoo Nareshini
Published: August 2021

Several herbs are well known for their nutritional applications. The reported study tested some herbs for their efficacy as antioxidants. The herbs and combinations thereof were analyzed for antioxidant activity using two comparative methods: the beta-carotene bleaching method and through measurement by the Rancimat apparatus. The efficacy of the antioxidants was also tested in a cosmetic base cream. The concentration of the natural antioxidant vitamins, such as vitamin C, vitamin E and beta-carotene was determined by analytical methods. The methods used for analysis provided adequate results for interpretation. All herbs exhibited antioxidant activity, at comparable levels. The two methods used for analysis showed variable results, as previous researchers have shown. In terms of antioxidant potency, the herbs were ranked as follows: fenugreek > coriander > oregano > sage (beta-carotene bleaching method), oregano > sage > coriander > fenugreek (Rancimat method). Oregano and sage were good synergists, when combinations of herbs were used. Fenugreek, unlike the other herbs under investigation, is a prooxidant when used at higher concentrations. A direct relationship was observed between the concentration of herbs and antioxidant potency for sage, oregano and coriander. Fenugreek which is prooxidant at higher concentrations, should be used as an antioxidant independently rather than a synergist. This was the most important finding in the reported study. Similar antioxidant activities of the herbs were observed in the base cosmetic formulation. The reported study has provided an adequate base for further quantitative research into the innovative topic of antioxidants.
Phytoremediation of heavy metals using Amaranthus dubius
Authors:   , Mellem John Jason
Published: August 2021

Phytoremediation is an emerging technology where specially selected and engineered metal-accumulating plants are used for bioremediation. Amaranthus dubius (marog or wild spinach) is a popular nutritious leafy vegetable crop which is widespread especially in the continents of Africa, Asia and South America. Their rapid growth and great biomass makes them some of the highest yielding leafy crops which may be beneficial for phytoremediation. This study was undertaken to evaluate the potential of A. dubius for the phytoremediation of Chromium (Cr), Mercury (Hg), Arsenic (As), Lead (Pb), Copper (Cu) and Nickel (Ni). Locally gathered soil and plants of A. dubius were investigated for the metals from a regularly cultivated area, a landfill site and a sewage site. Metals were extracted from the samples using microwave-digestion and analyzed using Inductively Coupled Plasma – Mass Spectroscopy (ICP-MS). Further experiments were conducted with plants from locally collected seeds of A. dubius, in a tunnel house under controlled conditions. The mode of phytoremediation, the effect of the metals on the plants, the ability of the plant to extract metals from soil (Bioconcentration Factor - BCF), and the ability of the plants to move the metals to the aerial parts of the plants (Translocation Factor - TF) were evaluated for the different metals. Finally, A. dubius was micro-propagated in a tissue culture system with and without exposure to the metal, and the effect was studied by electron microscopy.
Determination of the heterotrophic and autotrophic active biomass during activated sludge respirometric batch assays using molecular techniques
Authors:   , Ismail Arshad
Published: August 2021

Activated sludge models now in use worldwide for the design and operation of treatment systems use hypothetical concentrations of active organisms. In order to validate and calibrate model outputs, concentrations and activities of organisms responsible for nitrification and denitrification need to be reflected by actual measurements. This research has been initiated by the observation of an increasing gap of suitable techniques that exist in the direct measurement and separation of active biomass components, responsible for COD removal and denitrification.

Forensic Engineerings Believe It or Not
Authors: Shefchick Thomas P.
Published: August 2021

Laymen and occasionally experienced electrical engineers have reported unusual occurrences over the years which have been attributed to the mystical nature of electricity. Since electricity cannot be seen, heard, smelled or tasted but is very powerful, i.e. lightning, electrocution and computers, it has acquired a supernatural reputation. However, electricity is not supernatural but is governed by the laws of nature. This paper will illustrate three instances where damage was attributed to the mystical nature of electricity

The Circle of Forensic Engineering Practice
Authors: Anderson James D.
Published: August 2021

Today there is an increase of the so-called expert looking for easy money. These individuals control the cost by skipping the formalities of Discovery and scientific analysis by simply asking their clients, What do you want me to say? The practice can not be stopped by publishing position papers or complaining to state registration boards. But, the onslaught of these individuals can be stopped by professional forensic engineers following the full circle of our practice. The paper will discuss what is meant by that circle. That circle is the examination of every technical aspect of each case. If we technically analyze what the other technical positions are and prepare the client for what to expect, we will have traveled that circle, done our job, and hopefully served justice and the truth.

Wood Truss Failure - The Obvious Isnt Always The Answer
Authors: Yaxley Wilbur T.
Published: August 2021

Contrasting Opinions On The Failure Of A Metal Plate Connected Wood Truss Will Be Discussed. A Fundamental Lack Of Definition And Information For The Erection Bracing Is In Many Cases The Reason For The Failure During The Critical Erection Phase. Bracing For The Temporary System Before The Installation Of Permanent Bracing Is Very Well Documented, But Similar Information For Use During The Erection Phase Is Lacking In The Literature For The Metal Plate Connected Wood Truss Industry. The Erection Contractor Is Forced To Decide, Without A Realistic Set Of Guidelines, How Much Erection Bracing Is Necessary To Assure The Safety Of The Job Without Excessive Cost. Even With Adequate Erection Bracing A Faulty Truss Can Cause An Accident.

Published: August 2021

The Fact That Vehicles On The Highways Create Aerodynamic Forces That Affect The Other Vehicles They Pass Or Meet Has Been Well Known For Some Time. A Number Of Technical Papers Released In The Early 70S Addressed This Phenomenon And A Few Concluded That The Aerodynamic Forces Created By A Large Passing Vehicle Were Significant Enough To Cause The Vehicle Being Passed To Become Momentarily Unstable. This Paper Deals With The Reconstruction Of An Accident Caused By A Tractor Trailer Passing A Station Wagon Towing A Travel Trailer And Causing The Station Wagon And Travel Trailer To Go Out Of Control, Go Off A 65 Foot Bridge, Then Burn, Killing Both Occupants. The Decision In Favor Of The Plaintiff In This Case Was The First Such Decision In Georgia In A Non-Contact Accident.
