Three-dimensional Numerical Study on the Metal Rotating Spray Transfer Process of High-current GMAW
Authors: Xiao Lei , Fan Ding , Huang Jiankang 
Published: August 2020

Abstract
Gas metal arc welding (GMAW) is one of the most widely used processes in automated welding technologies. Its efficiency relies on the travel speed and wire melting rate. Increasing the welding current is the most effective way to improve them. However, the welding quality will decrease because of the unstable metal rotating spray transfer in the high-current GMAW which will aggravate the welding spatters and instability. To study the high-current metal transfer mechanism and then propose schemes of improvements and controls, a three-dimensional numerical model based on the volume-of-fluid (VOF) method is typically preferred. Unfortunately, the rotating spray transfer is extremely complicated, therefore the research community has focused on simplified models without considering the energy conservation to make analysis manageable for the unstable metal transfer process. Using our created model, the metal transfer of high-current GMAW with shielding gas of different conductivities has been studied by analyzing acting forces and fluid flows in the metal liquid column, especially for the contributions of the self-induced electromagnetic force, equivalent volume force of the capillary pressure of the surface tension (Named surface tension force in this work), static arc pressure. It is found that the unbalanced electromagnetic force greatly promotes the metal rotating motion in 500A MIG with pure argon shielding gas and it pushes the metal liquid column to rotate. Considering the arc constricting effect in active shielding gas by simply changing the arc conductivity, it is found that the metal liquid column no longer rotates, it turns to swing since the unbalanced electromagnetic force is large enough to break the rotating motion. The calculated results of the metal liquid column deflected angle and rotating/swing frequency agree well with the experiment of high-speed camera observations.

Authors: Edet Clement Kevin , Wegbom Anthony Ike , Kiri Prof. Victor Alangibi 
Published: August 2020

Abstract
Introduction: The primary healthcare workers (PHCWs) face a higher risk of infection associated with their occupation, due to inadequate supplies of personal protective equipment (PPE), inappropriate use of PPEs, and insufficient knowledge on infection prevention and control. Therefore, this study aimed to assess the preparedness for COVID-19 by PHCWs in Rivers State, Nigeria. Method: A cross-sectional survey was conducted involving the healthcare workers at the public primary healthcare facilities across the 23 local government areas (LGAs) of Rivers State, Nigeria. The descriptive statistics of mean ± standard deviation and percentage were used to present quantitative and categorical variables respectively. The preparedness for COVID-19 was measured by knowledge, attitude and preventive practices (KAP) towards the disease. The association between the KAP and demographic characteristics was tested with the Chi-square test, while the associations existing among the KAP constituents were evaluated with the Pearson correlation coefficient. Statistical significance was evaluated at P<0.05. Results: Out of 460 questionnaires distributed, 412 respondents participated in the survey, indicating a response rate of 89.6%. The proportion of respondents with good scores in knowledge, attitude, and COVID-19 related practices was 86.4% (10.66 ± 2.40), 85.0% (8.28 ± 1.94), and 97.3% (8.34 ± 1.39) respectively. Gender, occupation, and years of experience were associated with knowledge, while years of experience and marital status were associated with attitude and preventive practices. Knowledge score also had significant positive linear associations with both attitudes and practices ( scores toward COVID-19. Conclusion: Our findings revealed the level of PHCWs preparedness to fight COVID-19 in Rivers State. We suggest that public health education programs on infection prevention and control should be sustained. Furthermore, training should be tailored to meet the peculiarities of the different categories of healthcare workers and years of practice.

Published: August 2020

Abstract
This study investigated the adsorption of methylene blue with natural and artificial zeolite. The effect of pH, contact time, initial concentration and adsorbent dose on adsorption was also investigated. An artificial dye was prepared. Adsorption removal efficiency was low at pH = 2, 3 and 4 but it was quite high at pH = 7. It was determined that the contact time reaches equilibrium within 60 minutes in the adsorption of methylene blue with natural and artificial zeolite. The initial dyestuff concentration for both adsorbents was 5 mg/L. For the removal of methylene blue, a 0.5 g natural and artificial zeolite dosage was sufficient. In order to express the adsorption of natural and artificial zeolite on methylene blue, Langmuir, Freundlich, Temkin and Dubinin-Radushkevich (D-R) isotherm models were examined. In the isotherm study, both natural and artificial zeolite adapted to the Langmuir isotherm model. Langmuir correlation coefficient was 0.998 for artificial zeolite and 0.993 for natural zeolite. Both adsorbent materials best fit into the pseudo-second kinetic model with similar correlation coefficient values of 0.999.

Published: August 2020

Abstract
For the utilization of nitrogen and phosphorus in rural sewage tailwaters after biological treatment, four systems were examined regarding their ability to purify tailwaters of rural domestic sewage: a hydroponic vegetable system (HV), a subsurface flow constructed wetland (SFCW), a compound system with HV followed by SFCW (HV-SFCW), and a compound system with SFCW followed by HV (SFCW-HV). Parameters of the four systems were optimized to maximize the utilization efficiency of nitrogen and phosphorus, and the characteristics and pollutant removal efficiency of the process were investigated. Moreover, the edible security of vegetables was also evaluated. Results showed that the optimal hydraulic loadings for the four systems were 0.2, 0.3, 0.3, and 0.3 m3/(m2·d) (the lowest being the HV), respectively. In the combined system of HV-SFCW, high contribution proportions of the HV unit to the removal of COD, TN, and TP were obtained, reaching 46.7%, 58.1%, and 53.7%. The heavy metal content of plants harvested met the standards of the National Food Safety Standard Limit of Pollutants in Food (GB 2762-2012). Overall, the compound HV-SFCW system achieved the best performance, ensuring that effluent water quality met national standards and realized the effective utilization of nitrogen and phosphorus.

The Klf6 Super-enhancer Determines Klf6 Sensitivity to BRD4 Inhibitors in Human Hepatoma (HepG2) Cells
Authors: Ri KumChol , Ri MyongRyong , Song YongJae , Kim KyuHwan , Kim Chol 
Published: August 2020

Background:
The Klf6 gene, belonging to Krüppel-like family of C2H2 zinc finger transcription
factors, is strongly associated with tumor formation through high somatic mutations in
carcinomas of the prostate, liver, colon, stomach, lung, neck, pituitary gland and nervous system.
Recently, Klf6 super-enhancer which strongly regulates Klf6 gene expression has been identified,
and the function of Klf6 super-enhancer which regulates cell growth was studied.

Objective:
The development of inhibitors targeting BRD4-binding super-enhancers is a potential
target therapeutic strategy for tumor therapy. However, the suppression of Klf6 super-enhancer
function by BRD4 inhibitors is not known.

Methods:
CRISPR-Cas9 editing technique was used for the Klf6 super-enhancer deletion experiment,
and the expression levels of several genes for cell clones were detected by qRT-PCR analysis
and Western blotting. Cell proliferation assay was applied to evaluate the functional role of
Klf6 super-enhancer using several BRD4 inhibitors. The interaction of several BRD4 inhibitors
against the target protein was analyzed by molecular docking simulation.

Results:
JQ-1, a human BRD4 inhibitor, inhibited Klf6 gene expression and its activity in HepG2
cells in a time and dose-dependent manner while simultaneously inhibiting cell growth. Besides,
BETd-246, a human BRD4 inhibitor, strongly inhibited Klf6 gene expression, significantly inhibited
cell growth, and exhibited higher efficacy than JQ-1. Molecular docking studies revealed that
some key residues were critical for ligand-receptor interactions by forming hydrogen bonds with ligands
(JQ-1: ASN140, BETd-246: ASN140, TYR106, LYS65, GLN58, MET105, and MET53).

Conclusions:
Our findings suggest that KLF6 is regulated by Klf6 super-enhancer and the targeting
of Klf6 super-enhancer by BRD4 inhibitors may be an effective therapeutic strategy for liver cancer
therapy.
Predicting Election Results from Twitter Using Machine Learning Algorithms

Published: July 2020

Introduction:
In the present scenario, the social media network plays a significant role in
sharing information between individuals. This incorporates information about news and events that are
presently occurring in the worldwide. Anticipating election results is presently turning into a fascinating
research topic through social media. In this article, we proposed a strategy to anticipate election results
by consolidating sub-event discovery and sentimental analysis in micro-blogs to break down as well as
imagine political inclinations uncovered by those social media users.

Methods:
This approach discovers and investigates sentimental data from micro-blogs to anticipate the
popularity of contestants. In general, many organizations and media houses conduct a pre-poll review and
obtain expert’s perspectives to anticipate the result of the election, but for our model, we use Twitter data to
predict the result of an election by gathering information from Twitter and evaluate it to anticipate the result
of the election by analyzing the sentiment of twitter information about the contestants.

Results:
The number of seats won by the first, second, and third party in AP Assembly Election
2019 has been determined by utilizing Positive Sentiment Scores (PSS’s) of the parties. The actual
results of the election and our predicted values of the proposed model are compared, and the outcomes
are very close to actual results. We utilized machine learning-based sentimental analysis to
discover user emotions in tweets, anticipate sentiment score, and then convert this sentiment score to
parties' seat score. Comprehensive experiments are conducted to check out the performance of our
model based on a Twitter dataset.

Conclusions:
Our outcomes state that the proposed model can precisely forecast the election results with
accuracy (94.2 %) over the given baselines. The experimental outcomes are very closer to actual election
results and contrasted with conventional strategies utilized by various survey agencies for exit polls and
approval of results demonstrated that social media data can foresee with better exactness.

Discussion:
In the future, we might want to expand this work into different areas and nations of the
reality where Twitter is picking up prevalence as a political battling tool, and where politicians and
individuals are turning towards micro-blogs for political communication and data. We would likewise
expand this research into various fields other than general elections and from politicians to
state organizations.

Authors: B. R. BHARATH , DAMLE HRISHIKESH , GANJU SHIBAN , DAMLE LATHA 
Published: August 2020

Objective: Ivermectin is an FDA-approved, broad-spectrum anti-parasitic agent. It was originally identified as an inhibitor of interaction between the human 29 immunodeficiency virus-1 (HIV-1) integrase protein (IN) and the Importin (IMP) α/β1 30 heterodimers, which are responsible for IN nuclear import. Recent studies demonstrate that ivermectin is worthy of further consideration as a possible SARS-CoV-2 antiviral.
Methods: We built the pathogen-host interactome and analyzed it using PHISTO. We compared Ivermectin and plant molecules for their interaction with Importin α3 (IMA3) using molecular docking studies.
Results: A phytochemical ATRI001 with the lowest binding energy-7.290 Kcal/mol was found to be superior to Ivermectin with binding energy-4.946 Kcal/mol.
Conclusion: ATRI001 may be a potential anti-SARS-CoV-2 agent; however, it requires clinical evaluation.

Abstract
Parenting is a factor that is directly related to child development. This study aims to explore the parenting style among children with developmental delay. This qualitative study nested in a Child Growth and Development Cohort Study that was conducted in Bogor in October 2019. Six children aged 2 to 6 years with developmental delay were recruited in this study. Mother of these children were purposely selected as informants and participated in individual interview about parenting Style of Baurimnd. The mothers as the main caregiver of their children applied control and warmth parenting. The mothers did not know if their children suffered from developmental delay and they had never been informed about this problem by health workers. Economic factors were the reason why mother did not check up their child development. Family had an important role to prevent developmental delay of their children. Parents did not realize that their children had developmental delay, thus there was no specific parenting style applied to cope with this problem. Early detection and early developmental stimulation for children are necessary. It is important to develop indirect counselling media, both electronic and printed media, for mothers of children with developmental delay; hence they can perform early detection and early developmental stimulation by themselves.

Pola asuh merupakan faktor yang terkait langsung dengan perkembangan anak. Penelitian ini bertujuan untuk mengeksplorasi pola asuh orang tua pada anak dengan hambatan perkembangan. Penelitian ini merupakan bagian dari Studi Kohor Tumbuh Kembang Anak yang dilaksanakan di Bogor pada bulan oktober 2019. Jumlah sampel 6 anak yang mengalami hambatan perkembangan berusia 2 hingga 6 tahun, informan adalah ibu dari anak yang mengalami hambatan perkembangan tersebut, yang dipilih secara purposive untuk diwawancara terkait informasi dimensi pola asuh Baumrind. Pengasuhan anak lebih banyak dilakukan oleh ibu dengan menerapkan pola asuh kontrol dan kehangatan. Ibu tidak tahu jika anak mereka mempunyai hambatan dalam perkembangannya dan belum pernah mendapatkan informasi tersebut dari tenaga kesehatan. Faktor ekonomi merupakan alasan ibu tidak melakukan pemeriksaan terhadap perkembangan anak. Keluarga berperan besar dalam mengatasi hambatan perkembangan anak. Orang tua tidak menyadari bahwa anaknya memiliki hambatan perkembangan sehingga tidak ada pola asuh spesifik yang diterapkan untuk menangani masalah tersebut. Kegiatan deteksi dini dan stimulasi perkembangan sejak dini perlu digiatkan, serta pentingnya mengembangkan media penyuluhan tidak langsung baik media elektronik maupun media cetak, bagi ibu yang memiliki anak dengan hambatan perkembangan agar bisa melakukan deteksi dini dan stimulasi terhadap gangguan tumbuh kembang anak secara mandiri.

Abstrak
Terapi bekam merupakan salah satu terapi kesehatan tertua di dunia. Hal ini dibuktikan, bekam sudah ada di dalam catatan kedokteran tertua Papyrus Ebers, yang ditulis 1550 SM pada era Mesir kuno. Terapi bekam sendiri terbagi menjadi dua jenis, yakni bekam basah dan bekam kering. Yang membedakan antara bekam basah dan bekam kering adalah keberadaan darah yang dikeluarkan. Kajian (review) ini bertujuan untuk mengetahui mekanisme, keamanan, dan juga manfaat bekam. Dari beberapa artikel penelitian yang telah didapatkan, umumnya dengan pemanfaatan bekam mendapatkan hasil yang baik. Sementara jumlah penelitian pemanfaatan bekam masih sedikit, sehingga masih diperlukan penelitian lebih lanjut untuk mendapatkan bukti yang lebih baik dan meyakinkan. Di Indonesia, pelayanan kesehatan tradisional bekam diatur dalam PMK 61 tahun 2016 tentang Pelayanan Kesehatan Tradisional Empiris. Secara regulasi pelayanan tradisional bekam tidak direkomendasikan karena termasuk ke dalam tindakan dengan perlukaan. Padahal, kenyataannya pelayanan tradisional bekam ini ada dan diminati oleh masyarakat. Melihat khasiat dan antusias masyarakat, diharapkan pelayanan tradisional bekam tetap dapat dilakukan di Griya Sehat dengan menjadikan faktor keamanan sebagai fokus utama dalam pelayanan. Hal ini tentunya dapat didukung dengan adanya pembinaan secara menyeluruh mengenai keamanan pelayanan kesehatan tradisional bekam terhadap para praktisi bekam.

Cupping therapy is one of the oldest health therapies in the world. This was proven by an ancient Egypt paper in 1550 SM as cupping was mentioned in their medical journal. Cupping therapy has been classified into two categories, which were wet and dry cupping. The difference between wet and dry cupping is the presence or absence of blood being released. This literature review aims to find out the history, development, and also the use of cupping. From some research articles that have been obtained, we generally get good results from the use of the cupping method. However, because research on cupping utilization is still limited, further research is needed to obtain better and more convincing evidence. Regulation of traditional cupping service is not recommended because it is an invasive action, when in fact this traditional cupping service exists and is in demand by the community. Seeing the efficacy and enthusiasm of the community, it is hoped that traditional cupping services can still be carried out in a griya sehat with regard to efficacy. Of course, can be supported by the existence of comprehensive guidance on the efficacy of traditional cupping health services for cupping practitioners.
