Hydrazine Formation via NiIII-NH2 Radical Coupling in Ni-Mediated Ammonia Oxidation
Authors: Gu Nina , Oyala Paul H. , Peters Jonas
Published: August 2020

Given the diverse mechanistic possibilities for the overall 6e-/6H+ transformation of ammonia to dinitrogen, identification of M(NHx) intermediates involved in N–N bond formation is a central mechanistic challenge. In analogy to water oxidation mechanisms, which widely invoke metal oxo intermediates, metal imide and nitride intermediates have commonly been proposed for ammonia oxidation, and stoichiometric demonstration of N–N bond formation from these metal-ligand multiply bonded species is well-precedented. In contrast, while the homocoupling of M–NH2 species to form hydrazine has been hypothesized as the key N–N bond forming step in certain molecular ammonia oxidation systems, well-defined examples of this transformation from M–NH2 complexes are essentially without precedent. This work reports the first example of net ammonia oxidation mediated by a molecular Ni species, a transformation carried out via formal NiII/NiIII oxidation states. The available data are consistent with a NiIII–NH2 intermediate featuring substantial spin at N undergoing N–N bond formation to generate a NiII2(N2H4) complex. Additional and structurally unusual Nix(NyHz) species – including a Ni2(trans-N2H2) complex – are characterized and studied as intermediates in the Ni-mediated ammonia oxidation cycle described herein.

MITOLOGI DAN EKSISTENSI SASTRA INDONESIA DALAM PUSARAN POSHUMANISME Mythology and The Existence of Indonesian Literature in The Posthumanism's Vortex
Authors: Aji Gabriel Fajar Sasmita
Published: August 2020

Dunia paradigma dan perspektif keilmuan pada masa kini sedang dalam “kekacauan” lewat kehadiran bermacam terminologi, seperti posmodernisme, pasca kebenaran (post truth), disrupsi, dan juga poshumanisme. Masing-masing membentuk pusarannya sendiri-sendiri dan seolah-olah masing-masing memiliki legalitas dan kebenarannya untuk muncul sebagai eksisensi yang sangat menopang perkembangan kualitas peradaban umat manusia di atas bumi ini. Sementara itu, dalam konnteks ke-Indonesia-an, berbagai pusaran tersebut pasti mau tidak mau, lambat maupun cepat, tentu akan memiliki dampak, mengingat Indonesia merupakan bagian dari peradaban dunia yang sedang dan terus dalam proses peradaban global. Alih-alih sekadar sebagai objek dari berbagai pusaran tersebut, mampukah Indonesia mengembangkan pola atau strategi yang karakteristik sehingga mampu juga hadir sebagai agen pengubah bagi peradaban tersebut? Jika peradaban Barat berhasil mengglobalkan peradabannya ke berbagai penjuru dunia, lepas dari aspek kolonialisme dan modernismenya, lewat kebesaran mitologi Yunani, yang merupakan sumber peradabannya, mungkinkah Indonesia juga mampu menghadirkan diri secara independen dan berkarakteristik lewat mitologi? Di sinilah peranan eksistensi sastra yang akan akan menjadi salah satu pilar utamanya. Terlebih, sebagai bangsa yang sangat beragam dengan kekayaan etnik, yang tentu juga kaya akan mitologi, sastra Indonesia tentu sudah memiliki modalnya. Bersama-sama dengan bangsa-bangsa lain serumpun, Indonesia bisa menciptakan nilai-nilai dalam menegosiasi peradaban dunia yang sedang sibuk dengan berbagai paradigma dan perspektif yang beridentitaskan “post.”.

Kardiyovasküler hastalıklar (KVH) dünya genelinde ölümlerin üçte birinden sorumludur. Bu hastalıklarda görülen ortak patolojik durum aterosklerozdur. Ateroskleroz, erken safhalarında endotelyal hücre aktivasyonu/disfonksiyonunun görülmesi sebebiyle inflamatuar bir hastalık olarak nitelendirilmektedir. Ateroskleroz patolojisinin kötü kolesterol olarak bilinen düşük yoğunluklu lipoprotein kolesterolün (LDL-C) kandaki düzeyinin artması ve iyi kolesterol olarak bilinen yüksek yoğunluklu lipoprotein kolesterolün (HDL-C) düzeyinin ise azalması gibi lipit metabolizma bozuklukları (dislipidemi) ile karakterize olduğu birçok çalışmada gösterilmiştir. Çeşitli epidemiyolojik çalışmalarda Tip II diyabetli (T2D) hastaların ateroskleroz ve Koroner Arter Hastalığı (KAH) komplikasyonları geliştirme riskinin daha yüksek olduğu belirtilmiştir. Çinko parmak motif transkripsiyon faktörü ailesinin üyesi olan Kruppel benzeri faktörler (KLF) normal biyolojik süreçlerde ve patolojik durumlarda gerekli olan genlerin aktivitesini düzenlemektedirler. Yapılan çalışmalarda KLF14’ün aterosklerotik KVH’da önemli rolü olduğu gösterilmiştir. Bu derlemede KLF14’ün ateroskleroz patofizyolojisindeki rolüne değinilecektir.

Authors: Hasimun Patonah , Zakaria Hasballah
Published: August 2020

ABSTRAK Hasil studi epidemiologi diketahui bahwa trigliserida merupakan salah satu factor resiko independent terjadinya penyakit kardiovaskular walaupun target kadar low density lipoprotein (LDL) telah tercapai dengan obat statin. Diduga terdapat hubungan antara kadar trigliserida dengan elastisitas arteri. Kekakuan arteri telah diakui berkaitan erat dengan penyakit kardiovaskular. Penelitian ini bertujuan untuk mengetahui efek hipertrigliseridemia terhadap tingkat kekakuan arteri pada model hewan tikus Wistar yang diinduksi pakan tinggi lemak dan fruktosa 25%. Sejumlah 10 ekor tikus dikelompokkan secara acak menjadi 2 kelompok terdiri dari kelompok control normal menerima pakan normal dan kelompok control positif menerima pakan tinggi lemak dan air minum fruktosa 25% selama 28 hari. Pengukuran pulse wave velocity (PWV), denyut jantung, dan kadar trigliserida serum dilakukan pada hari ke 28. Hasil menunjukkan, kelompok kontrol positif mengalami kenaikan kadar trigliserida serum yang disertai dengan meningkatnya nilai PWV dan denyut jantung yang menunjukkan terjadinya kekakuan arteri yang berbeda bermakna secara statistik terhadap kelompok kontrol normal (p<0.05). Hasil dapat disimpulkan bahwa terdapat hubungan positif antara kadar trigliserida dengan kekakuan arteri. Semakin tinggi kadar trigliserida meningkatkan kekakuan arteri sehingga resiko kardiovaskular semakin meningkat. Kata kunci : trigliserida, kekakuan arteri, denyut jantung, kardiovaskular   ABSTRACT Epidemiological studies report that triglycerides are an independent risk factor for cardiovascular disease even though the target level of low density lipoprotein (LDL) has been achieved with statin drugs. It is suspected that there is a relationship between triglyceride levels and arterial elasticity. Arterial stiffness has been recognized as being closely related to cardiovascular disease. This study aims to determine the effect of hypertriglyceridemia on arterial stiffness in animal models of Wistar rats induced by a high-fat diet and 25% fructose in drinking water. A total of 10 rats were randomly divided into 2 groups consisting of a normal control group receiving normal feed and a positive control group receiving a high-fat diet and 25% fructose in drinking water for 28 days. Measurements of pulse wave velocity (PWV), heart rate, and serum triglyceride levels were carried out on day 28. The positive control group experienced an increase in serum triglyceride levels accompanied by an increase in PWV and heart rate that was statistically significantly different (p <0.05) compared to the group normal. The results concluded that there was a positive relationship between triglyceride levels and arterial stiffness. Higher triglyceride levels increase arterial stiffness. it increases the risk of cardiovascular disease. Keywords : triglyceride, arterial stiffness, heart rate, cardiovascular
Optimization of Building Configuration in Vertical Residential Housing towards Outdoor Thermal Comfort: Case Study of Tambora Flats, Jakarta, Indonesia
Authors: Rizqi Khairani Ayu , Prayitno Budi
Published: August 2020

Population growth in Indonesia is not offset by the construction of urban facilities and infrastructure and the improvement of urban services. In densely populated urban areas with narrow residential conditions, the demand for shelter is higher, causing an increase in the price of land and housing. One of the efforts in responding to this problem in the Special Capital Region of Jakarta is to build vertical residential or flats. This study aimed to determine the level of outdoor thermal comfort of Tambora flats in Jakarta, which have air temperatures ranging 26–29°C and air humidity of 76–92%. Existing flats were simulated with the Envi-MET 3.1 software, with the first stage being to determine the height of the building and material of the building, the street, and then assessing the existing outdoor thermal comfort level by inputting climatic data. Overall, the thermal comfort index values of both existing and planned model building configurations of Tambora flats and its surrounding area were at the standard level for a humid climate. Of our models, model B had the best potential to provide thermal comfort to humans in the area of the flats. In order to implement the proposed model building configuration with optimal outdoor thermal comfort in real buildings, future research should focus on a wider range of aspects, including diversity and density of buildings, and neighborhood type.

The main purpose of this article is to identify the most characteristic features of an intruder's personality and to formulate recommendations aimed at improving the process of investigating criminal offenses related to falsification of excise goods. The article deals with the issue of theoretical interpretation of the concept of "criminalistic characterization of crimes" and "typology of personality" as its element. The analysis of the reference paper is given regarding the study of the typology of persons committing criminal offenses; as well as the problems that arise in determining the subject of the crime and the ways to solve them. The types of persons committing criminal offenses connected with forgery of excisable products as exogenous and endogenous types of intruders are investigated; classified by the object of encroachment, the nature of criminal acts, the degree of public danger. The concepts of socially-adoptive, socially-disadaptive type of personality of persons who commit this category of a criminal offense are disclosed. The structure of the personality of the intruder who deals in the falsification of excisable goods has been compiled and examined through socio-demographic, criminally-legal, socially significant physiological features and moral properties. The analysis of methods for establishing a suspect person is given, the main types of malefactors and their functions are identified in the production of a surrogate excise product. Recommendations for persons conducting investigations into criminal cases related to forgery of excise goods are developed.

El virus SARS-CoV-2 causante de la enfermedad COVID-19 es altamente contagioso y debido a que la propagación nosocomial ha sido bien documentada, se han implementado directrices que incluyen el uso de elementos de pro­tección personal (EPP) con el objetivo de minimizar el riesgo de contagio en el personal de la salud. Secundario al uso continuo, repetitivo y prolongado de estos dispositivos, se pueden desencadenar procesos inflamatorios cutáneos tales como: dermatitis de contacto, prurito o urticaria por presión, o exacerbar procesos inflamatorios preexistentes como dermatitis seborreica, acné, entre otros. Por lo anterior, la Asociación Colombiana de Derma­tología y Cirugía Dermatológica (AsoColDerma), en alianza con el Hospital Universitario Centro Dermatológico Federico Lleras Acosta, como ente asesor del Gobierno colombiano, nos permitimos hacer las siguientes recomen­daciones encaminadas a reducir el riesgo de lesiones cutáneas derivadas del uso de los equipos de protección personal.

Estas recomendaciones son de orientación general para la práctica clínica, y el personal de la salud las debe se­guir de forma individualizada, de acuerdo con sus necesidades y con los recursos disponibles.

Authors: Abdulamir Ahmed Sahib , Hassen Salah Mahdi
Published: August 2020

Background: The human cytomegalovirus (HCMV) is a widely distributed virus among humans and is included within the sexually transmitted viruses. Because of its low detection rate in semen, the impact of HCMV on sperm formation and its vertical transmission within the sperm cells have not been studied sufficiently.                                                                                                     

Objectives: To investigate the association of viral infections present in the lower genital tract of males and relationship among males infertility.

Methods: ELISA and RT-PCR technique of 100 semen and serum specimens, collected over 8 months from males investigated for infertility, were retrospectively assessed, by screening anti-human Herpes Simplex Virus (HCMV) IgM and IgG in the serum and detection of HSV DNA in seminal fluid.                                                                                        

Results: One hundred seminal fluid and blood samples were taken from men and investigated for infertility over a period of 8 months from July 2016 to February 2017. The seminal fluids and serum of patients mentioned to the laboratory from the fertility clinics of Kamal AL-samarai hospital and outer clinics. The investigations were conducted to find the HCMV detection rate in the seminal fluid of infertile men and to evaluate the impact of the viral infection on the major sperm parameters. Blood and seminal fluid were collected from 100 infertile males. The results were shown that 24/100 (24.0%) were positive for IgM and 86/100 (86.0%) were positive for IgG of HCMV. In case of the control group, results were (1.0%) positive for anti-HCMV IgM antibodies, while (20.0%) positive for anti-HCMV IgG antibodies in a control group, using ELISA test.                          

 The PCR showed that out of 100 samples 24 (24.0%) gave positive results for HCMV patients, while 7 (7.0%) positive for HCMV in the control group.

Conclusions: Using sensitive procedures for assays, seminal samples of asymptomatic infertile patients showed an unexpectedly high incidence of the sexually transmitted pathogens.

The current research aims to identify the difficulties of using a sample of faculty members in the Faculty of Basic Education / Mustansiriya University for modern education technology in their teaching, and the extent of their actual use of the variables (academic qualification, academic qualification, specialization and years of experience). The researchers designed a research tool to identify the views of the members of the teaching staff at the Faculty of Basic Education after their distribution and to verify the validity and truthfulness of the questionnaire by presenting them to a group of arbitrators, professors of education, professors of psychology, measurement and evaluation, And a group of faculty members included in the sample of the study. The questionnaire contains the difficulties that prevent the effective use of technology from the point of view of faculty members and whether there is a relationship between variables (scientific title, specialization, academic qualification, and years of experience in university education(.

The percentages, frequencies and weighted mean were used to analyze the data. The researchers also used the Wilcoxon test to identify the mean differences between the study groups using the spss program.

The results of the research revealed the existence of some obstacles that hinder the use of teaching technology by teaching staff members. The most important of these are the lack of necessary equipment and infrastructure, some of which are related to the weakness of training courses in the use of modern teaching technology in teaching. The research presented a number of recommendations and suggestions.

Weak Presence of Women in Microelectronics: Analysis and Suggestions of the French Training Network to be More Attractive
Authors: Bonnaud Olivier André
Published: August 2020

The engineering sciences, and more particularly microelectronics, are a field where the presence of women is very low, although they should logically account for half of the staff. The electronic and microelectronics sector is growing rapidly due to the development of the Internet and connected objects more generally known as the digital society. Industrialists in the field are lacking in skills and have a large number of job vacancies which are difficult to fill. These jobs cover almost all the professional facets that are entitled " Skilled manpower shortage". The arrival in this sector of a large number of female candidates could reduce this deficit and increase the sector's capacity for innovation through their difference of appreciation on many societal aspects. This paper discusses and analyses the presence of French young women in science studies from secondary school to doctorate level by linking this behavior to societal aspects. It then proposes approaches that are currently being carried out by the national academic network at the French level with the profession in the context of the implementation of an electronic sector by the government. These approaches aim to limit the loss of female candidates to other fields and to increase the attractiveness for young girls.
Zero Temperature Coefficient behavior for Ellipsoidal MOSFET
Authors: Camillo Luciano Mendes , Braga de Lima Marcos Paulo , Peixoto Marco Aurélio Pinhel , Correa Marcello Marcelino , Gimenez Salvador Pinillos
Published: August 2020

The zero temperature coefficient (ZTC) is investigated by three-dimensional numerical simulations in the Metal-Oxide-Semiconductor (MOS) Field Effect Transistor (MOSFET) with the ellipsoidal (EM) and conventional rectangular gate geometries (CM), considering the same channel widths (W), gate areas (Ag) and bias condition (BC).   In this work an improved simple model which predicts the ZTC point taking into account only the mobility degradation factor (c) and threshold voltage (Vth) parameters as function of temperature is proposed in the linear and saturation operation regions. The analysis takes into account the temperature variations of the threshold voltage and the mobility degradation factor. Although simple, the model predictions present a good agreement with the numerical simulations results.
Numerical Simulation of the Temperature on the Metallization of an Integrated Circuit and its Impact on Interconnect Lifetime
Authors: Nunes Rafael Oliveira , Bohorquez J. L. R. , De Orio R. L.
Published: August 2020

This paper demonstrates a finite element model to investigate the temperature change of the interconnects of an integrated circuit due to the power dissipation of the transistors in the substrate. The temperature of the local interconnect is more significantly affected, exhibiting an increase of 49 K and 34 K, for the Metal 1 and Metal 2, respectively. We discuss the impact of the temperature increase in the electromigration and, as a consequence in the lifetime of an operational amplifier, which demonstrates the importance of considering the metallization temperature distribution in the design stage.
Using the Hexagonal Layout Style for MOSFETs to Boost the Device Matching in Ionizing Radiation Environments
Authors: Peruzzi Vinicius Vono , Cruz William , Da Silva Gabriel Augusto , Simoen Eddy , Claeys Cor , Gimenez Salvador Pinillos
Published: August 2020

This paper describes an experimental comparative study of the matching between conventional (rectangular gate shape) and Diamond (hexagonal gate geometry) n-channel Metal-Oxide-Semiconductor (MOS) Field Effect Transistors (MOSFETs), which were manufactured in an 130 nm Silicon-Germanium Bulk Complementary MOS (CMOS) technology and exposed to different X-rays Total Ionizing Doses (TIDs). The results indicate that the Diamond layout style with alpha () angle equal to 90˚ for MOSFETs is capable of boosting the device matching by at least 17% regarding the electrical pa-rameters studied (Threshold Voltage and Subthreshold Slope) as compared with the conventional MOSFET counterparts, considering that they present the same gate area, channel width, bias conditions and for the same TID. This is due to the Longitudinal Corner Effect (LCE). Parallel MOSFETs with Different Channel Length Effect (PAMDLE) and Deactivation of Parasitic MOSFETs in the Bird’s Beak Regions Effect (DEPAMBBRE) present in the structure of Diamond MOSFETs. Therefore, the Diamond layout style can be consid-ered an alternative hardness-by-design (HBD) layout strategy to boost the electrical performance and TID tolerance of MOSFETs enabling analog or radio-frequency CMOS inte-grated circuits (ICs) applications.

Authors: Mota Barbosa da Silva Lucas , Cardoso Paz Bruna , De Souza Michelly
Published: August 2020

This work presents an analysis of the behavior of the effective mobility of graded-channel FD SOI transistors using an Y-Function-based technique. Low field mobility, linear and quadratic attenuation factors were extracted from two-dimensional numerical simulations. The influence of the length of both channel regions over these parameters was analyzed. The parameters extracted from experimental data were used in a SPICE simulator, showing that it is possible to simulated GC SOI MOSFET using a regular SOI MOSFET model, by adjusting its parameters.
UTBB Thermal Coupling Analysis in Technological Node Level
Authors: Costa Fernando José , Doria Renan Trevisoli , Doria Rodrigo Trevisoli
Published: August 2020

The main goal of this work is to perform a first-time analysis of the thermal cross-coupling in a system composed by some devices in an integration node degree composed by advanced UTBB SOI MOSFETs through numerical simulations, validated with experimental data from the literature. In this analysis, it could be observed that devices located on the channel length direction provoke a reduced thermal coupling and devices with their drain region next to each other suffer of an increased thermal coupling due to the lumped thermal energy. It also could be observed a degradation in some electrical parameters and in the thermal properties of a device under the influence of surrounded devices biased.
Effect of Interface Traps on the RTS Noise Behavior of Junctionless Nanowires
Authors: Picoli Marcos , Trevisoli Renan , Doria Rodrigo T.
Published: August 2020

This work presents a study on the effects of single interface traps throughout the Junctionless Nanowire Transistor (JNT). The results are obtained by analyzing the Random Telegraph Signal noise of the device, which consists of an exception of the generation-recombination noise. The results obtained are mostly from numerical simulation, validated through experimental data. As in physical devices, it is impossible to obtain a single trap in specific locations, we have used a distribution of traps with similar characteristics in a way that they behave like a single trap. The results show the behave considering a set of traps distributions, using an exponential model. The traps are distributed from the conduction band to the valence band.

NARRATIVAS SOBRE A MATEMÁTICA ESCOLAR: memórias e experiências discentes
Authors: Evangelista Maria Tereza Fernandino , Passos Cármen Lúcia Brancáglion
Published: August 2020

Este é um recorte de uma pesquisa de doutorado realizada junto a estudantes de uma escola pública onde atuo como professora de Matemática. Trata-se de um estudo orientado pela perspectiva da Pesquisa Narrativa (CLANDININ & CONNELLY, 2011) e, por assim o ser, é uma investigação que elegeu aexperiência para estudo, em particular, as experiências de três jovens com a Matemática no decurso da formação escolar de cada um, bem como as minhas, enquanto professora e pesquisadora que experiencia o próprio ato de pesquisar. O foco é conhecer e compreender, narrativamente, as trajetórias dessas experiências e, assim, aprofundar os modos de, a elas, atribuir sentido. Para a construção dos textos, optamos por solicitar a escrita de narrativas autobiográficas e realizar entrevistas narrativas individuais. Portanto, compartilhamos belas e instigantes histórias que confirmam o grande potencial formativo das narrativas no contexto educacional. No presente artigo, focaremos em um dos participantes, cujas narrativas revelaram marcas sobre o processo de ensino e aprendizagem da Matemática, sinalizaram para o redirecionamento de práticas pedagógicas, problematizaram estratégias de ensino da Matemática, provocaram reflexões e questionamentos sobre os sentidos e significados da Matemática ensinada nas escolas básicas e extrapolaram os limites da sala de aula e da escola, sinalizando que para além da dimensão cognitiva o processo educativo não se efetiva alheio às necessidades afetivas e formativas dos jovens. Em postura de compreensão narrativa das narrativas, junto aos jovens, este texto foi composto permeado pelas experiências narradas e pelas que tive ao longo do processo de pesquisar, aprofundar e redigir, ora como professora de Matemática, ora como pesquisadora, sempre em posição de inacabamento, em busca de melhores tons.
