A sand composite with surface gel coating containing alkylamine toward the removal and immobilization of complex metal ions from electroplating wastewater
Authors: Chen Feng , Tao Wenhong , Ng Dickon H. L. , Zhang Luteng , Liu Shiquan 
Published: May 2020

Abstract
SiO2 gel was formed on the grain surface of silica sand by hydrolysis and condensation of tetraethyl orthosilicate in water with the addition of 1-butylamine. The resultant product was a composite consisting of sand grains with mesoporous silica coating containing alkylamine inside. This composite exhibited basicity in the wastewater from copper electroplating due to its release of amine. As a result, the strongly acidic wastewater was neutralized and the co-precipitation of complex metal ions occurred. It was shown that up to 12 major metal ions in the wastewater could be simultaneously removed under static condition at room temperature by using the sand composite. The Fe and Cu in the wastewater could be removed completely, while the concentrations of Al, Cd, Ti, V, and Zn in the wastewater were reduced by two to three orders of magnitude. After the removal of multiple metal ions from the electroplating wastewater, the used sand was further applied as a raw material for making a silicate glass. The glass was chemically stable and thus the heavy metal ions from the wastewater were immobilized.

Objective:
Heart dysfunctions are the major complications of trastuzumab in patients with
Human Epidermal growth factor Receptor-2 (HER2)-positive breast cancers.

Methods:
In this study, the cytotoxicity of trastuzumab on H9c2 cardiomyoblasts was demonstrated,
and the proteome changes of cells were investigated by a tandem mass tagging quantitative approach.
The Differentially Abundant Proteins (DAPs) were identified and functionally enriched.

Results:
We determined that carvedilol, a non-selective beta-blocker, could effectively inhibit
trastuzumab toxicity when administrated in a proper dose and at the same time. The proteomics analysis
of carvedilol co-treated cardiomyoblasts showed complete or partial reversion in expressional levels
of trastuzumab-induced DAPs.

Conclusion:
Downregulation of proteins involved in the translation biological process is one of the
most important changes induced by trastuzumab and reversed by carvedilol. These findings provide
novel insights to develop new strategies for the cardiotoxicity of trastuzumab.
A Snapshot of SARS-CoV-2 Genome Availability up to April 2020 and its Implications: Data Analysis
Authors: Mavian Carla , Marini Simone , Prosperi Mattia , Salemi Marco 
Published: May 2020

Background
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has been growing exponentially, affecting over 4 million people and causing enormous distress to economies and societies worldwide. A plethora of analyses based on viral sequences has already been published both in scientific journals and through non–peer-reviewed channels to investigate the genetic heterogeneity and spatiotemporal dissemination of SARS-CoV-2. However, a systematic investigation of phylogenetic information and sampling bias in the available data is lacking. Although the number of available genome sequences of SARS-CoV-2 is growing daily and the sequences show increasing phylogenetic information, country-specific data still present severe limitations and should be interpreted with caution.

Objective
The objective of this study was to determine the quality of the currently available SARS-CoV-2 full genome data in terms of sampling bias as well as phylogenetic and temporal signals to inform and guide the scientific community.

Methods
We used maximum likelihood–based methods to assess the presence of sufficient information for robust phylogenetic and phylogeographic studies in several SARS-CoV-2 sequence alignments assembled from GISAID (Global Initiative on Sharing All Influenza Data) data released between March and April 2020.

Results
Although the number of high-quality full genomes is growing daily, and sequence data released in April 2020 contain sufficient phylogenetic information to allow reliable inference of phylogenetic relationships, country-specific SARS-CoV-2 data sets still present severe limitations.

Conclusions
At the present time, studies assessing within-country spread or transmission clusters should be considered preliminary or hypothesis-generating at best. Hence, current reports should be interpreted with caution, and concerted efforts should continue to increase the number and quality of sequences required for robust tracing of the epidemic.
Identidade e Sabedoria: a Reflexão Teológica como Veritatis Gaudium
Authors: Gonçalves Paulo Sérgio Lopes 
Published: May 2020

Objetiva-se, neste artigo, apresentar epistemologicamente a teologia como sabedoria que produz a alegria da verdade. Justifica-se este objetivo a necessidade de afirmar a identidade da teologia em meio ao contexto de pós-modernidade e de pluralismo teológico, para que não se torne uma ciência que utilize a identidade de outras ciências. Ao identificar a teologia como sabedoria, realça-se o seu vínculo com a revelação divina, que tem na sabedoria pré-existente o sujeito que realiza a criação, encarna-se na história humana e é o ápice de todo movimento revelador de Deus. Essa sabedoria é teorizada na teologia em sua relação com o mundo e com o ser humano, em toda a sua historicidade, dramas, tensões e perspectivas. Essa teologia sapiencial se torna, então, uma theologia mundi¸ que, concebida como scientia fidei, cujo assunto é Deus em sua relação com o mundo habitado pela humanidade, torna-se uma scientia Dei mundi. Para atingir o objetivo proposto, será decifrada teologicamente a revelação como fundamento da teologia, apresentada a configuração da teologia na relação entre Escritura e Tradição e mostrada a teologia como sabedoria ou, propriamente, como ciência sapiencial da fé revelada, que incide na história do mundo e do homem, para tornar-se contemporânea de cada época histórica.
KARAKTERISTIK DIELEKTRIK ISOLATOR POLIMER RESIN EPOKSI BERBAHAN PENGISI ABU TONGKOL JAGUNG
Authors: Indah Amelya 
Published: May 2020

Pengembangan isolator polimer semakin meningkat dikarenakan sifat dielektrik isolator polimer lebih baik dibanding kaca dan keramik, konstruksi relatif lebih ringan, ketahanan kimia yang baik, ketahanan yang tinggi terhadap asam, memiliki sifat kedap air (hidrophobik) dan proses pembuatannya yang relatif lebih cepat dibandingkan isolator keramik dan kaca. Adapun kekurangannya yakni bahannya kurang tahan terhadap perubahan cuaca yang menyebabkan kekuatan mekanis menurun dan kerusakan fisik isolator. Kekurangan tersebut dapat diperbaiki dengan menambahkan bahan pengisi (filler) pada bahan isolator, seperti pasir silika, ataupun abu arang yang banyak mengandung silika. Penelitian ini mengkaji karakteristik dielektrik isolator polimer berbahan pengisi abu arang tongkol jagung. Bahan resin epoksi yang di gunakan adalah Dyglicidyl Ether Of Bisphenol-A (DGEBA) sebagai bahan dasar dan Metaphenylene Diamine (MPDA) sebagai bahan pengeras dengan perbandingan campuran 2:1 dan dicampurkan bahan pengisi (filler) dengan komposisi 0 gr, 15gr, 30gr. Pengujian dilakukan pada kondisi kering dan basah. Hasilnya Korona yang terjadi pada sampel dengan filler 30gr lebih lama dibandingkan dengan sampel dengan filler 15gr, dan nilai tegangan tembus yang terjadi pada sampel dengan filler 30gr lebih tinggi dibandingkan dengan sampel dengan filler 15gr. Dengan demikian peningkatan filler secara bertahap dapat memperbaiki nilai tegangan tembus pada sampel isolator

Intisari — Setiap yang berputar memiliki potensi energi kinetik, tidak terkecuali putaran kubah masjid. Penelitian ini bertujuan untuk mengetahui potensi pemanfaatan kubah putar masjid sebagai penghasil energi listrik skala kecil. Generator yang diuji cobakan adalah generator magnet permanen dan generator DC yang dirangkaikan dengan turbin kubah putar. Pengujian dilakukan di dua lokasi, di Jembatan Musi 2 Palembang dan di perairan Sungsang Kabupaten Banyuasin untuk mengukur besaran tegangan dan arus output yang dihasilkan pada berbagai kecepatan angin menggunakan multimeter dan anemometer. Hasil penelitian menunjukkan bahwa tegangan yang dihasilkan oleh putaran kubah masjid menggunakan generator magnet permanen mampu mencapai 14,21 V pada kecepatan angin 3,8 m/det dibandingkan dengan generator DC yang hanya mencapai 3 V pada kecepatan angin 8 m/det. Jika ditinjau dari besaran arus, generator magnet permanen menghasilkan arus konstan sebesar 0,3 A sedangkan pada generator DC arus yang dihasilkan tidak terukur karena nilainya yang amat kecil. Penelitian ini menunjukkan bahwa kubah putar masjid dapat dijadikan sebagai turbin angin pada daerah yang memiliki kecepatan angin rendah.

Abstract - Every spinning has kinetic energy potential; the mosque dome is no exception. This study aims to determine the potential use of the mosque's turning dome as a producer of small-scale electrical energy. Two types of the generator were tested, which were permanent magnet generator and DC generator, which were coupled with a rotary dome turbine. The test was carried out at two locations, at Palembang Musi 2 Bridge and in the waters of Sungsang, Banyuasin Regency, to measure the amount of voltage and output current generated at various wind speeds using a multimeter and anemometer. The results showed that the voltage generated by the mosque's dome rotation using a permanent magnet generator was able to reach 14.21 V at wind speeds of 3.8 m / sec compared to DC generators, which only reached 3 V at 8 m / s wind speed. When viewed from the amount of current, permanent magnet generators produce a constant current of 0.3 A while in DC generators, the current generated is not measurable because the value is minimal. This research shows that the mosque's rotary dome can be used as a wind turbine in areas that have low wind speeds.

The Effect of Fidgeting On Student Concentration Levels
Authors: Nugroho K.A. , Kurnianingtyas M.C.D. 
Published: May 2020

Concentration is the ability needed to solve a problem. Students in learning also need concentration (DePorter et al., 2010). Unfortunately students have difficulty concentrating on doing a job. To help concentrate, students play pen, spin coins, play cellphones and other fun activities. To meet this goal, an agitated repellent device such as fidget spinner and fidget cube was made (Plafke, 2016). The benefits of spinner fidget for increasing concentration are still questionable (Schecter et al., 2017). Therefore, quantitative research is needed to prove the claim that fidget spinner can increase concentration. Unfortunately, there is currently no quantitative research that tests the effectiveness of these tools to increase short-term memory. The concentration level of a person can be measured using the Stroop test. Stroop tests utilize primitive cognitive operations, offering clues to the basic process of attention. The variable studied is Reaction Time for Correct Answer (RTCA), which is the amount of reaction time in answering correctly divided by the number of correct answers. The results of this study are the use of fidget spinner not having a significant effect on differences in the results of measurement of RTCA. The use of fidget spinner does not provide a significant difference in average error between not using fidget spinner and using fidget spinner.
ДИФФЕРЕНЦИАЛЬНЫЙ СПОСОБ ОБНАРУЖЕНИЯ ВИТКОВЫХ ЗАМЫКАНИЙ В ТРЕХФАЗНОМ ТРАНСФОРМАТОРЕ
Authors: Мустафин Рамиль 
Published: May 2020

Измерены напряжения холостого хода, пропорциональные соответствующим магнитным потокам трехфазного трансформатора общего назначения с использованием дифференциальных методов, направленных на обнаружение витковых замыканий в обмотках трехстержневых трансформаторов.
Стандартный метод определения витковых замыканий основан на измерении тока холостого хода и измерении мощности потерь. В дополнение к ним для определения наличия витковых замыканий в трехфазных линейных трансформаторах предлагается применять дифференциальные методы, хорошо известные в релейной защите. Методы основаны на том, что витковое замыкание увеличивает магнитное сопротивление фазного стержня сердечника трансформатора, в фазной обмотке которого присутствует витковое замыкание. При подаче однофазного напряжения на обмотку фазы В в обмотках боковых фаз А и С линейного трехфазного трансформатора должны индуцироваться одинаковые по фазе и амплитуде напряжения. При соединении обмоток фазы А и С встречно, и измерении дифференциального сигнала разности напряжений фаз А и С происходит следующее. Если в исходном, неповрежденном состоянии, дифференциальный сигнал был близок к нулю, то витковое замыкание в одной из боковых фаз А или С вносит дисбаланс, и дифференциальный сигнал возрастает. Дифференциальный сигнал легко измерим на фоне близкого к нулю дифференциального сигнала в неповрежденном состоянии трансформатора, что обусловливает высокую чувствительность дифференциального метода к наличию витковых замыканий. При возникновении виткового замыкания на обмотке центральной фазы В необходимо учитывать дифференциальный сигнал в неповрежденном состоянии трансформатора.

Abstrak. Pada saat masyarakat penutur bahasa Austronesia datang di Kepulauan Indonesia, kawasanini bukanlah suatu daerah kosong tidak berpenghuni. Beberapa pulau di Kepulauan Indonesia telahdihuni oleh populasi lain. Akibat adanya kontak antar-komunitas tersebut mengakibatkan prosesadaptasi, inovasi, dan interaksi budaya yang khas sebagaimana tercermin pada perkembanganteknologi alat kerang, teknologi pelayaran dan domestikasi hewan yang dikuasai masyarakat penuturbahasa Austronesia. Tahapan proses migrasi masyarakat penutur bahasa Austronesia di KepulauanIndonesia dapat dirangkum sebagai berikut: terjadi intrusi budaya baru di Kepulauan Indonesia yangdibawa oleh Austronesia. Akibat dari peristiwa tersebut, terjadi perkembangan budaya Neolitik diKepulauan Indonesia, disebabkan oleh adaptasi, evolusi dan interaksi antara masyarakat pendatangAustronesia dengan komunitas Non-Austronesia yang telah menghuni kawasan ini sejak masasebelumnya. Interaksi antar-budaya yang intensif menyebabkan integrasi budaya Austronesia danNon-Austronesia di Kepulauan Indonesia. Abstract. Austronesian Migration and Its Implication on Cultural Development in IndonesianArchipelago. When Austronesian language speakers came to Indonesian Archipelago, this regionis not an empty place but had already inhabited by other population. The unique processes ofadaptation, innovation, and culture interaction of Austronesian people in this new region arereflected on the development of shell tool technology, navigation technology, plant cultivation andanimal domestication. In summary, the stages of Austronesian migration in Indonesian Archipelagoare as follows: Intrusion of a new culture that was brought to the Indonesian Archipelago by theAustronesian people, which caused innovation of Neolithic culture in Indonesian Archipelago due tocultural adaptation, evolution, and interaction between the Austronesian speakers (the newcomers)with the indigenous Non-Austronesian communities. Intensive inter-cultural interactions havecreated a cultural integration between the Austronesians and Non-Austronesians in the IndonesianArchipelago.
KONFLIK HORISONTAL WARISAN BUDAYA, MEGALITIK SITUS GUNUNG PADANG
Authors: Sulistyanto Bambang 
Published: May 2020

Abstrak. Konflik warisan budaya Situs Gunung Padang merupakan isu baru yang muncul pada 2012, akibat perbedaan dalam memaknai warisan budaya. Bagi kalangan arkeologi, Gunung Padang hanyalah situs megalitik “biasa” yang dikenal dengan istilah punden berundak. Tetapi bagi Tim Terpadu Riset Mandiri, Situs Gunung Padang adalah piramida dan diduga berusia jauh lebih tua dari Piramida Mesir. Konflik horisontal Gunung Padang adalah konflik perbedaan paradigma arkeologi yang berdampak pada perbedaan pandangan dalam menafsirkan keberadaan tinggalan budaya.Konflik tersebut, merupakan konflik murni yang terbatas pada ranah kepentingan Ilmu Pengetahuan tanpa ada intervensi oleh berbagai faktor, termasuk faktor politis. Disisi lain arkeologi sudah lama menjadi ajang pergulatan pemikiran para ahli. Salah satu faktor penyebabnya adalah karena kajian pokok arkeologi bersifat post-facto yang terjadi tidak sekarang, tetapi ratusan bahkan ribuan atau jutaan tahun silam. Pada sisi lain, namanya pengetahuan itu sebenarnya bersifat relatif dan subyektif,karena telah dipengaruhi oleh berbagai kepentingan. Oleh karena itu, pengetahuan yang benar atau realitas masa lampau itu tidak ada, yang ada hanyalah pengetahuan masa lampau versi masyarakat masa kini. Perdebatan dalam ranah ilmu pengetahuan merupakan hal yang biasa. Jika konflik Gunung Padang dapat diselesaikan dengan benar, justru akan memberikan manfaat, salah satunya mendorong ke arah perubahan yang lebih baik. Abstract. Horizontal Conflict Regarding A Cultural Heritage: The Megalithic Site of GunungPadang. Conflict about a cultural heritage, Gunung Padang Site, is a new issue that surfaced in 2012 due to different views in interpreting a cultural heritage. To archaeologists, Gunung Padangis a “typical” megalithic site, which is known as terraced structure. However, to Tim Terpadu Riset Mandiri (Integrated Team of Independent Research), it was a pyramid much older than the ones in Egypt. The horizontal conflict about Gunung Padang is a conflict caused by different archaeological paradigms, which impacted on different views in interpreting the existence of cultural remains. It is apurely conflict, which scope is limited to the domain of Academic purposes with no interventions from various factors, including political factor. Archaeology has long been an arena of debates by experts. One of the reasons is because the main study of archaeology is post-facto – does not happen in recent time, but hundreds and even thousands and millions of years ago. On the other hand, knowledge/science is relative and subjective in nature because it is influenced by various interests. Therefore there is no true knowledge/science or reality of the past. What exists is knowledge about the past according to present-day people. Debates in knowledge/science domain are natural. In fact, if the conflict about Gunung Padang can be resolved in the right way, it will be a benefit, among others it will lead to a change for the better.
Users’ acceptance of financial technology in an emerging market (An empirical study in Indonesia)
Authors: Johan Suwinto 
Published: May 2020

This study seeks to investigate the factors that affect consumers’ use of financial technology in fulfilling their financial needs in the emerging market. The financial technology consists of payment gateway, peer to peer lending, online financial product offering, and financial literacy. The paper analyzes five major customers’ aspects, i.e., demography, psychography, banking literacy, technology awareness, and trust of regulatory that consist of 15 variables of customer responses. Those 15 variables explain individuals’ use of financial technology. The binary logit regression technique tests the research models. In the model, consumers’ acceptance (whether one will use financial technology) is operationalized by a dummy variable that equals one if the consumer accepts or is aware of the technology and zero otherwise. The total sample is 298 respondents. The respondents are mostly millennial generation (56 percent), university graduates (76 percent), individuals with the income level of B-Class and A-Class (67 percent), 95 percent of the respondents have bank accounts, and almost 99 percent of the respondents have social media accounts. The empirical results show that millennial-age customers with the income levels of B-Class and A-Class have the highest financial technology acceptance. Gender also influences the acceptance level of financial technology.

Authors: Cathcart-Rake William 
Published: May 2020

Abstract
Physician workforce shortages in rural areas are well-documented problems. The University of Kansas School of Medicine (KUSM) established the Salina regional medical campus (RMC) in response to the need to train more physicians interested in primary care in rural Kansas. Since its founding in 2011, thirty-eight students have completed their training on the Salina RMC and received their M.D. Twenty-eight graduates (74%) matched in primary care residencies; eighteen (44%) in family medicine. Eleven of the first sixteen graduates have finished residency and entered practice; nine are in Kansas, and seven of those are in rural Kansas. The Salina RMC has had early success in producing primary care physicians to serve rural Kansas.
