Authors: Idrus Arifudin , Ubaidillah Aji Syailendra , Warmada I Wayan , Maula Syafruddin
Published: April 2021

Brambang is one of the porphyry copper-gold prospects/deposits situated along eastern Sunda arc. This study is aimed to understand geological framework, alteration geochemistry and ore fluid characteristics of the prospect. Fieldworks and various laboratory analyses were performed including petrography, ore microscopy, rock geochemistry, chlorite chemistry and fluid inclusion microthermometry. The prospect is composed of andesitic tuff and diorite which are intruded by tonalite porphyries. Tonalite porphyries are interpreted as ore mineralisation-bearing intrusion. Various hydrothermal alterations are identified including potassic, phyllic, propylitic, advanced argillic and argillic types. Ore mineralisation is characterized by magnetite and copper sulfides such as bornite and chalcopyrite. Potassic alteration is typified by secondary biotite, and associated with ore mineralisation. Mass balance calculation indicates SiO2, Fe2O3, K2O, Cu and Au are added during potassic alteration process. Ore forming fluid is dominated by magmatic fluid at high temperature (450-600ºC) and high salinity (60-70 wt. % NaCl eq.). Hydrothermal fluid was diluted by meteoric water incursion at low-moderate temperature of 150-400ºC and salinity of 0.5-7 wt. % NaCl eq.

Comparison between Monoamine Oxidase A and B: role and effect in human diseases: A review
Authors: Reem aljanabi  , Mahmood salih  , Dawood aljanabi
Published: April 2021

MAOs are isoenzymes that occur in two isoforms Monoamine oxidases A and B. They are flavoproteins found in mitochondria and their role is to catalyze the oxidative deamination of monoamine neurotransmitters to their corresponding aldehydes. Both MAOs play a major role in the human body as they contribute to many illnesses. MAO plays an essential role in both peripheral; and central nervous system through affecting the levels of MAO neurotransmitters. MAO-A is generally concentrated in dopaminergic and norepinephrinergic neurons. Contrary to MAO-B, which is predominantly concentrated in serotoninergic neurons. By-product of MAOs which are aldehyde, ammonia, and H2O2 (which is considered reactive oxygen species) that is toxic at high concentration or it may lead to the generation of free Radicals. Free radicals considered as a starting signal in the generation of cancers. Also, MAO inhibition showed to decrease pressure overload and heart failure. This action is mainly related to the prevention of oxidative stress mainly (H2O2) apoptosis in cardiac muscle and improved bioavailability of Norepinephrine. MAO-A plays a totally different role from MAO—B in renal carcinoma. Ranging from Alzheimer disease, depression to cardiac myopathy, diabetes, kidney diseases, and cancers, MAO-A participates differently from MAO-B in these diseases. Therefore it is necessary to study their separate effect in human diseases and the consequences of their inhibition. In this review, we compare between MAO-A and MAO-B effect from many aspects that includes heart failure, renal carcinoma, breast cancer, esophageal cancer, prostate cancer, bladder cancer, glioma and diabetes. And finally, the role of MAO inhibitors and their effects also have been discussed.

Published: April 2021

The purpose of this work was to determine the C. albicans protein concentration at the subcutaneous introduction. The therapeutic  effect of C. albicans proteins has been studied in white mice.  Animals were injected  intraperitoneally with a suspension of C. albicans fungus.  After five days and repeatedly, after 14 days, mice were infected subcutaneously  with proteins of Candida cells of volume 0.2 mL. Fourteen days after each injection, the determination of the protective functions of the animal body has been carried out by the titer of specific C. albicans antibodies. According to the data obtained during studies on the treatment of candidiasis, it was found that in the subcutaneous administration after the first and second injection with a concentration of low molecular weight fraction of the C. albicans protein of 1, 2, 3, 4, and 5 mg/mL antibodies titers have doubled, indicating a lack of activation of the body's protective functions. Proteins of low molecular weight fraction of C. albicans with concentrations 1, 2, 3, 4, and 5 mg/mL do not activate the body's defence mechanisms.

Published: April 2021

The beneficial effects of sunlight in preventing bone-related disorders have been well-known for centuries. Vitamin D is a modified steroid, synthesised under the influence of sunlight in the skin. Low Vitamin D status has associated with a higher risk of pre-eclampsia in pregnant womens. The aim of this study was to undertake a systematic review of different studies investigating the association between Vitamin D levels and pre-eclampsia in pregnant womens. A systematic review was undertaken. MEDLINE, PUBMED, EMBASE, Google Scholar were searched. The review protocol was designed to answer the question. Search terms (Preeclampsia and Vitamin D or 1,25 dihydroxy vitamin D). The search was confined to peer-reviewed articles that were published in English and contained an abstract. Reference list of journal articles were also screened for additional citations fitting our search criteria. Twenty-Seven studies were included in the systematic review that investigates the association between Vitamin D and pre-eclampsia. The present systematic review concludes that maternal vitamin D deficiency in pregnancy is significantly associated with an elevated risk of preeclampsia. Pregnant womens should take vitamin D supplementation, expose themselves into the sunlight, and they should be physically active. Further taking Vitamin D supplementation in early pregnancy may be a simple way to reduce the risk of these adverse pregnancy outcomes.

Published: April 2021

Este artigo tem como objetivo investigar os movimentos que aconteceram no Twitter entre apoiadores e críticos ao governo do presidente Jair Bolsonaro em relação ao marco das 100 mil mortes no Brasil relacionadas à Covid-19, por meio de hashtags. Recorremos como suporte metodológico às obras Análise de redes para mídia social (RECUERO;ZAGO; BASTOS, 2018) e Redes Sociais na Internet (RECUERO, 2009), nas quais destacamos os principais indicadores a serem analisados: Indegree (grau de entrada); Betweenness (Grau de Intermediação); PageRank e Centralidade Eigenvector (centralidade de autovetor). Concluímos que os clusters formados entre opositores e apoiadores do governo não se divergem internamente, porém não chegam a efetivar conexões entre si, estabelecendo apenas interações filtradas em bolhas, nas quais acabam por contribuir para uma esfera pública cujas opiniões se reverberam em câmaras de eco, diluindo o diálogo entre o contraditório como princípio importante para a democracia.Palavras-chave: Câmaras de eco.

“O Brasil não pode parar”: racismo e desigualdade social na campanha publicitária do governo Bolsonaro.
Authors: Sanches Julio Cesar , Moisés Raika Julie , Souza Rhayller Peixoto da Costa
Published: April 2021

A campanha publicitária “O Brasil não pode parar” foi produzida pelo governo Bolsonaro no ano de 2020 com o intuito de justificar a contrariedade da política estatal brasileira em relação às recomendações dos organismos internacionais, que indicavam a importância do isolamento social no combate à pandemia do COVID-19. Expondo a necessidade de crescimento econômico e social, mesmo em tempos de pandemia e crise na saúde pública mundial, a narrativa da peça publicitária convocava as trabalhadoras e trabalhadores brasileiros a continuar com as atividades laborais. Partindo da análise das representações sociais do trabalho e da identificação dos corpos visibilizados pela campanha, buscamos apontar quais eram os sujeitos sociais que não deveriam parar de trabalhar: pessoas negras subalternizadas. Diante da análise do texto e do contexto do vídeo, acreditamos que o discurso produzido na campanha “O Brasil não pode parar” invocou as dinâmicas do racismo estrutural brasileiro, marcado pela manutenção das desigualdades sociais e pelo desprezo às vidas negras.Palavras-chave: Racismo.

Authors: Kudeken Victória Sayuri Freire dos Santos
Published: April 2021

O direito universal à saúde no Brasil surge a partir do Sistema Único de Saúde com a constituição de 1988. Os princípios organizativos são constituídos pela participação popular, a regionalização e a descentralização dos poderes federal, estadual e municipal, conferindo assim uma administração compartilhada e transparente com foco na equidade das práticas de saúde. Dessa forma, a apresentação dos dados epidemiológicos torna-se uma ferramenta para compreender os espaços e ações necessárias para o atendimento clínico e preventivo. O presente artigo tem como objetivo analisar algumas estratégias discursivas sobre a divulgação de dados do novo coronavírus a partir da publicação do “Placar da Vida” pelo Ministério da Saúde e as repercussões midiáticas e populares sobre as informações destacadas e omitidas no material de divulgação.Palavras-chave: Saúde pública.

Irrigation is an effort made by humans to irrigate agricultural land. Overall the irrigation system in Indonesia is an irrigation building that starts from a water taking area or a weir and distributes it to various agricultural areas through primary dividing channels to the quarter. This requires supporting infrastructure in the process of extracting / distributing water from water sources to irrigation plots. One of the main irrigation infrastructures is irrigation channels with a means of regulating or measuring the discharge at the upstream such as a water gauge board or manual peilchaal to measure the water level that passes through an irrigation channel. The main objective of this research is to plan a digital water level measuring instrument in the irrigation channel to make it easier for sluice guard officers or farmers to find out the flow rate that passes through an irrigation channel. The data that will be collected are primary data generated from the experimental results by comparing the results from manual and digital. These data are in the form of water level data on the Thomson measuring instrument to find the flow rate through the open channel model. Based on the research results, it can be concluded that the validation results obtained from digitization have a very high level of accuracy. The percentage value difference between the value obtained from the manual and digital level meter has an average value of 1-6%. The amount of this percentage is strongly influenced by the decimal digits that have not been compared to those read on the manual level meter. Therefore, in the future, its capacity to read the water level accurately to the nearest digit will be increased.

Published: April 2021

In this study, we focused on the quantitative analysis and decision-making of credit risk of the Micro, Small and Medium Enterprises (MSMEs) from the perspective of bank. Based on the data of 123 MSMEs, we extracted and processed information from the original data with theoretical analysis and feature engineering, and established an entropy weight-TOPSIS model to get the credit risk index of each MSME. Meanwhile, the credit strategy optimization model was constructed, and the DE algorithm was used to solve the credit strategy scheme for bank to each MSME. According to the relationship between the total annual credit of bank, interest rate and expected profit, we analyzed the partial sensitivity of the model and explored the maximum profitability of the bank and finally gave helpful suggestions. Our results have guiding significance for banks to manage and make decisions on the credit risk of MSMEs.

Taking the Zambezi River Basin as a typical case, this paper studied the location problem of dam group. Based on the topographical and elevation maps of the Zambezi River Basin, we evaluated each region by five indicators (Water head difference elevation, Geological environment, Climatic environment, Population distribution and Biodiversity), and selected the 22 candidate dam sites. Meanwhile, the relative feasibility index of dam construction is calculated by the entropy weight-grey correlation analysis. On this basis, combined with the water management capacity of the dam, a set coverage model of dam selection is established, and the neighborhood adaptive particle swarm optimization algorithm (NAPSO) is used to solve the 12 most suitable dam sites. Comparing with the water management capacity of the original Kariba Dam, the new dams’ water storage and flood control capacity, hydroelectric power generation capacity, domestic water supply capacity and other water supply capacity have been increased by 235.92%, 250.62%, 189.66% and 223.61% respectively. Our study can provide some guidance for the site selection project of river dam group.

How effective have measures by Central Banks been in mitigating the impact of financial crisis
Authors: Rimintsiwa Ibrahim
Published: April 2021

During the global financial crisis, central banks around the globe implemented a series of unconventional monetary policy measures such as quantitative easing among others to avert the impact of financial crisis on financial system. There exist numerous studies on this area of interest, with each guided by a specific view of the problem and selectively chosen empirical observations with regard to the different developments. This paper reviewed literature to ascertain the effectiveness of conventional monetary policy measures and unconventional monetary measures used in mitigating the impact of the 2007/2008 global financial crisis, specifically by the major central banks including the Federal Reserve, European Central Bank and Bank of England. The study used systematic quantitative assessment technique (SQAT) to determine a high quality of papers that have been reviewed in the study. The result proved that conventional monetary policy measures are still potent to deliver their desired objectives but inadequate in times of acute crisis. Empirical evidences proved that central banks have not practically abandoned the core elements of their pre-crisis monetary policy. Through a complex form of strengthening and reassessment, they have instead complimented, extended and somewhat improved their measures to mitigate the impact of the financial crisis. An important lesson of the crisis is that there is opportunity to reinforce central banks with macro prudential supervision and regulation. This should be seen as complementary to the existing monetary policy measure in order to deliver the twin objectives of price and financial stability.

Se propone un índice de sensación-observación-percepción del cambio climático (ISOP-CC) como variable de respuesta a partir de cinco indicadores (precipitaciones, temperaturas, plagas, vientos y heladas), con el objetivo de medir las reacciones culturales femeninas ante dichos eventos atmosféricos; a las respuestas se les asignaron valores que oscilan entre cero y cien por ciento. El estudio se llevó a cabo en tres localidades del municipio de San Salvador el Verde, ubicadas en la cuenca alta del río Atoyac, en la región conocida como Sierra Nevada de Puebla, México. Entre las variables independientes con impactos en el ISOP-CC se encuentran el gradiente altitudinal relacionado con el tipo de ecosistema y la cobertura forestal, los perjuicios por el cambio climático, la tenencia de la tierra, las actividades económicas del grupo doméstico, la cobertura forestal, las variables sociales y agroproductivas. Se concluye que las mujeres rurales tienen ISOP-CC diferenciales según la altitud de su asentamiento.

Published: April 2021

The Covid-19 pandemic has hit Indonesia since March 2020. Several policies have been issued by the Indonesian government to reduce the level of the spread of Covid-19. This policy has an impact on various fields of life, especially the economic sector in various sectors. This study was conducted to analyze the grouping of provinces whose economies are at risk of being affected by Covid-19 based on various economic sectors, namely the unemployment rate, the percentage of poor people, the provincial minimum wage, and the occupancy rate of hotels using cluster analysis. Cluster analysis was performed using several hierarchical methods, namely Simple, Complete, Average, and Centroid Linkage and Ward. The Cophenetic correlation coefficient (rCoph) was used to determine the best method, while the number of clusters was determined based on the Dunn, Connectivity, and Silhoutte indexes. The analysis result shows that Average Linkage is the best method with two clusters. The first cluster consists of all provinces in Indonesia except Papua, whose economy is highly at risk of being affected by Covid-19, characterized by a low percentage of the poor and a low provincial minimum wage, as well as high levels of open unemployment and hotel occupancy rates. Meanwhile, the second cluster consists of the Province of Papua, which is an economic group with a low risk of being affected by Covid-19. By looking at the impact of the Covid-19 disaster, the government can make recovery efforts and generalize economic recovery policies due to Covid-19 which have an impact on the economy of almost all provinces in Indonesia.

Published: April 2021

Small area estimation can be used to predict the population parameter with small sample sizes. For some cases, the population units that are close spatially may be more related than units that are further apart. The use of spatial information like geographic coordinates are studied in this research. Outlier contaminations can affect small area estimations. This study was conducted using simulation methods on generated data with six scenarios. The scenarios are the combination of spatial effects (spatial stationary and spatial non-stationary) with outlier contamination (no outlier, symmetric outliers, and non-symmetric outliers). The purpose of this study was to compare the geographically weighted empirical best linear unbiased predictor (GWEBLUP) and robust GWEBLUP (RGWEBLUP) with direct estimator, EBLUP, and REBLUP using simulation data. The performance of the predictors is evaluated using relative root mean squared error (RRMSE). The simulation results showed that geographically weighted predictors have the smallest RRMSE values for scenarios with spatial non-stationary, therefore offer a better prediction. For scenarios with outliers, robust predictors with smaller RRMSE values offer more efficiency than non-robust predictors.

Published: April 2021

Background: ‪Osteoarthrosis (OA) is the most common disease affecting mankind. There are many physiotherapeutic methods of treating OA symptoms. One of them is whole body cryotherapy (WBCT). The aim of this study was to present the impact of WBCT combined with kinesiotherapy on functional efficiency and changes in plasma concentrations of serotonin and melatonin in patients with lumbar spine OA.. Material and methods: ‪60 patients underwent a series of WBCT combined with kinesiotherapy (group A). 60 patients underwent a series of kinesiotherapy alone (group B). Before and after the therapy patients were examined by Rolland Morris Disability Questionnaire (RMDQ), and blood samples were collected for laboratory assessment. Results: ‪Following therapy, the functional efficiency (RMDQ) improved by 33% in both study groups (p < 0.0001). After the therapy, both in the group of patients undergoing WBCT combined with exercises (group A, p = 0.032) and the cryotherapy alone (group B, p < 0.0001), the plasma melatonin concentration significantly increased. The rise of plasma serotonin concentrations was higher in group B as compared to group A, but in both study groups the increase in plasma serotonin was statistically significant (p < 0.0001).. Conclusions: ‪WBCT combined with therapeutic exercises as well as kinesiotherapy used alone resulted in an increase in melatonin and serotonin plasma levels and an improvement in functional efficiency in patients with lumbar spine OA.
Rhythmic Techniques in Deaf Hip Hop
Authors: Maler Anabel , Komaniecki Robert
Published: April 2021

The art of signed music involves the use of rhythmicized signs from a signed language, such as American Sign Language (ASL), in a musical context. Signed music encompasses a variety of subgenres, including ASL hip hop or “dip hop.” A typical dip hop performance involves a Deaf or hard-of-hearing artist simultaneously performing vocalized and signed rapping over a looped background beat. Although dip hop emerged as a grassroots movement in the early 1990s, it has received little analytical attention in the scholarly literature on hip hop. In this paper, the authors combine techniques adapted from analyzing rhythm in non-signed rap music with techniques adapted from analyzing non-rapped signed music to analyze the rhythmic flow of tracks by dip hop artists Sean Forbes, Wawa, and Signmark. The authors demonstrate that dip hop artists have developed genre-specific rhythmic paradigms and tropes to convey the periodicity and rhyme that are fundamental to rap music. Specifically, we address the alignment of rhythm and meter in signed and vocal rap and the conveyance of a repeated “beat” through rhythmic signing. The analyses of dip hop tracks reveal important differences between dip hop and vocal rap, as well as differences between the conventions of dip hop and ASL poetry.

Published: April 2021

Language skills are the most important part of language learning at primary schools that need to be taken seriously. If not, then this results in low writing skills of students in expressing ideas in writing. So, students' thinking skills or what so-called Higher Order Thinking Skills (HOTS) are essential to be developed by teachers through learning. This study aims to determine the implementation of the HOTS-based ESCOTING model in writing skills of fables at primary school level. The method used was a pre-experimental research design with a single treatment design (one-shot case study). The sample used in this study was 23 second-grade students of a primary school in Bandung. The results showed that there was a significant increase in student learning outcomes in writing skills. From these results it can be concluded that the implementation of the HOTS-based ESCOTING model can be used as a solution by the teacher to develop students' writing skills, especially in writing fables for the second-grade students.

Quando il Moderno cerca radici. Casa Balmelli di Tita Carloni e Luigi Camenisch
Authors: Navone Nicola
Published: April 2021

"The article reconstructs the genesis of Casa Balmelli, designed and built in Rovio
(Canton Ticino) in 1956-1957 by Tita Carloni and Luigi Camenisch. Among Carloni’s
first works in Ticino after the completion of his studies at the ETH Zurich, Casa
Balmelli has often been presented as an example of the current of Organic Architecture
that developed in Ticino in the 1950s and saw a particularly flourishing phase
in the following decade. However, while the house certainly embodies organic features
by aiming at a perfect integration with its surroundings through the use of natural
materials and the geometric reinterpretation of the landforms of its setting, its
internal spatial qualities have little to do, for instance, with Wrightian models. Rather,
the ordering function attributed to geometry is its most notable quality and is a
common denominator of the research conducted in Ticino on the organic architecture front: a geometry that relates to the characteristics of the site and seeks a certain degree of formal abstraction."
