Published: July 2020

Dynamics of pulse magnetic reversal of nanocell, composed of two magneto-one-axis nanoparticles, by short Gaussian pulse of magnetic field, was investigated. Such a dipole-bound system is multi-stable and has four equilibrium states. The conditions under which the nanocell is re-magnetized into one of three states or returned to the original configuration are revealed. It was shown that the nature of precession dynamics of magnetic moment and the choice of the final state of the nanocell depend on the amplitude and duration of the pulse, as well as on the mutual orientation of the light axes.

The results of studying unoccupied electronic states in the energy range from 5 eV to 20 eV above the Fermi level of ultrathin films of dimethyl-substituted thiophene-phenylene co-oligomers CH3-phenylene-thiophene-thiophene-phenylene-CH3 (CH3-PTTP-CH3) are presented. The films were deposited on two types of surface of polycrystalline Au: ex situ Au layer thermally deposited in a separate chamber, and on the in situ Au surface prepared inside the analytical chamber. The structure of the films was studied by X-ray diffraction (XRD). The formation of a superposition of the amorphous and crystalline phases with a period of 3.8 nm is discussed. Investigations of the energy positioning of the maxima of unoccupied electronic states and of the process of the formation of the potential boundary barrier were carried out by the method of total current spectroscopy (TCS). The maxima of the fine structure of the total current spectra (FSTCS) of the CH3-PTTP-CH3 film 5–7 nm thick did not differ when using different types of Au substrates and the surface of the ZnO semiconductor prepared by the atomic layer deposition (ALD) method. When the CH3-PTTP-CH3 layer was deposited both on the ex situ Au surface and on the in situ Au surface, a slight (about 0.1 eV) increase in the electronic work function was observed with an increase in the coating thickness to 5–7 nm. At such CH3-PTTP-CH3 film thicknesses, the electron work function was determined as 4.7 ± 0.1 eV for the ex situ Au substrate and 4.9 ± 0.1 eV for the in situ Au substrate. The possible influence of the processes of physicochemical interaction at the film – substrate interface on the formation of the potential boundary barrier in the structures under study is discussed.

Authors: Gurgel-Juarez Nalia , Perrier Marie-France , Hoffmann Tammy , Lannin Natasha , Jolliffe Laura , Lee Rachel , Brosseau Lucie , Flowers Heather
Published: July 2020

Background

Oral care is important to prevent buccal and systemic infections after an acquired brain injury (ABI). Despite recent advancements in the development of ABI clinical practice guidelines, recommendations for specific clinical processes and actions to attain adequate oral care often lack information.

Objective

This systematic review will (1) identify relevant ABI clinical practice guidelines and (2) appraise the oral care recommendations existing in the selected guidelines.

Methods

A search strategy was developed based on a recent systematic review of clinical practice guidelines for ABI. The protocol includes a search of MEDLINE, EMBASE, and DynaMed Plus databases, as well as organizational and best-practice websites and reference lists of accepted guidelines. Search terms will include medical subject headings and user-defined terms. Guideline appraisal will involve the Appraisal of Guidelines for Research and Evaluation II ratings, followed by a descriptive synopsis for oral care recommendations according to the National Health and Medical Research Council evidence levels.

Results

This project started in April 2019, when we developed the search strategy. The preliminary search of databases and websites yielded 863 and 787 citations, respectively, for a total of 1650 citations. Data collection will start in August 2020 and we expect to begin disseminating the results in May 2021.

Conclusions

Nursing staff may not have detailed recommendations on how to provide oral care for neurologically impaired patients. The findings of this review will explore the evidence for oral care in existing guidelines and improve outcomes for patients with ABI. We expect to provide adequate orientations to clinicians, inform policy and guidelines for best practices, and contribute to future directions for research in the ABI realm.

Digital Mental Health Resources for Asylum Seekers, Refugees, and Immigrants: Protocol for a Scoping Review
Authors: Raphiphatthana Buaphrao , Maulana Herdiyan , Howarth Timothy , Gardner Karen , Nagel Tricia
Published: July 2020

Background

Asylum seekers, refugees, and immigrants experience a number of risk factors for mental health problems. However, in comparison to the host population, these populations are less likely to use mental health services. Digital mental health approaches have been shown to be effective in improving well-being for the general population. Thus, they may provide an effective and culturally appropriate strategy to bridge the treatment gap for these populations vulnerable to mental health risks.

Objective

This paper aims to provide the background and rationale for conducting a scoping review on digital mental health resources for asylum seekers, refugees, and immigrants. It also provides an outline of the methods and analyses, which will be used to answer the following questions. What are the available digital mental health resources for asylum seekers, refugees, and immigrants? Are they effective, feasible, appropriate, and accepted by the population? What are the knowledge gaps in the field?

Methods

The scoping review methodology will follow 5 phases: identifying the research question; identifying relevant studies; study selection; charting the data; and collating, summarizing, and reporting the results. Searches will be conducted in the following databases: EBSCOhost databases (CINAHL Plus with Full Text, MEDLINE with Full Text, APA PsycArticles, Psychology and Behavioral Sciences Collection, and APA PsycInfo), PubMed, and Scopus. Additionally, OpenGrey, Mednar, and Eldis will be searched for gray literature. All primary studies and gray literature in English concerning the use of information and communication technology to deliver services addressing mental health issues for asylum seekers, refugees, and immigrants will be included.

Results

This scoping review will provide an overview of the available digital mental health resources for asylum seekers, refugees, and immigrants and describe the implementation outcomes of feasibility, acceptability, and appropriateness of such approaches for those populations. Potential gaps in the field will also be identified.

Conclusions

As of February 2020, there were no scoping reviews, which assessed the effectiveness, feasibility, acceptability, and appropriateness of the available digital mental health resources for asylum seekers, refugees, and immigrants. This review will provide an extensive coverage on a promising and innovative intervention for such populations. It will give insight into the range of approaches, their effectiveness, and progress in their implementation. It will also provide valuable information for health practitioners, policy makers, and researchers working with the population.

Unmuting Medical Students’ Education: Utilizing Telemedicine During the COVID-19 Pandemic and Beyond
Authors: Iancu Ariella Magen , Kemp Michael Thomas , Alam Hasan Badre
Published: July 2020

Due to the coronavirus disease (COVID-19) pandemic, medical schools have paused traditional clerkships, eliminating direct patient encounters from medical students’ education for the immediate future. Telemedicine offers opportunities in a variety of specialties that can augment student education during this time. The projected growth of telemedicine necessitates that students learn new skills to be effective providers. In this viewpoint, we delineate specific telehealth opportunities that teach core competencies for patient care, while also teaching telemedicine-specific skills. Schools can further augment student education through a variety of telemedicine initiatives across multiple medical fields. The explosion of telemedicine programs due to the pandemic can be a catalyst for schools to integrate telemedicine into their current curricula. The depth and variety of telemedicine opportunities allow schools to continue providing high-quality medical education while maintaining social distancing policies.

Published: July 2020

Background

Existing health disparities based on race and ethnicity in the United States are contributing to disparities in morbidity and mortality during the coronavirus disease (COVID-19) pandemic. We conducted an online survey of American adults to assess similarities and differences by race and ethnicity with respect to COVID-19 symptoms, estimates of the extent of the pandemic, knowledge of control measures, and stigma.

Objective

The aim of this study was to describe similarities and differences in COVID-19 symptoms, knowledge, and beliefs by race and ethnicity among adults in the United States.

Methods

We conducted a cross-sectional survey from March 27, 2020 through April 1, 2020. Participants were recruited on social media platforms and completed the survey on a secure web-based survey platform. We used chi-square tests to compare characteristics related to COVID-19 by race and ethnicity. Statistical tests were corrected using the Holm Bonferroni correction to account for multiple comparisons.

Results

A total of 1435 participants completed the survey; 52 (3.6%) were Asian, 158 (11.0%) were non-Hispanic Black, 548 (38.2%) were Hispanic, 587 (40.9%) were non-Hispanic White, and 90 (6.3%) identified as other or multiple races. Only one symptom (sore throat) was found to be different based on race and ethnicity (P=.003); this symptom was less frequently reported by Asian (3/52, 5.8%), non-Hispanic Black (9/158, 5.7%), and other/multiple race (8/90, 8.9%) participants compared to those who were Hispanic (99/548, 18.1%) or non-Hispanic White (95/587, 16.2%). Non-Hispanic White and Asian participants were more likely to estimate that the number of current cases was at least 100,000 (P=.004) and were more likely to answer all 14 COVID-19 knowledge scale questions correctly (Asian participants, 13/52, 25.0%; non-Hispanic White participants, 180/587, 30.7%) compared to Hispanic (108/548, 19.7%) and non-Hispanic Black (25/158, 15.8%) participants.

Conclusions

We observed differences with respect to knowledge of appropriate methods to prevent infection by the novel coronavirus that causes COVID-19. Deficits in knowledge of proper control methods may further exacerbate existing race/ethnicity disparities. Additional research is needed to identify trusted sources of information in Hispanic and non-Hispanic Black communities and create effective messaging to disseminate correct COVID-19 prevention and treatment information.

Published: July 2020

Hypercholesterolemia is still a health problem today because it is associated with the onset of cardiovascular disorders with various complications. High cholesterol levels carried by the blood will accumulate in the arteries that cause atherosclerosis. Blood clots and blockage of blood vessels can result in the stroke or heart attack. Flavonoids that are found in purple sweet potato leaves are quercetin. Quercetin has antioxidant effects that can improve blood vessel endothelial function, reduce LDL sensitivity to free radical effects, and reduce blood lipid levels. This study aims to determine the effect of ethanol extract of purple sweet potato leaves on LDL cholesterol level of hypercholesterolemia rat. The experiment was conducted experimentally using 2 groups of Wistar rats (each group consisting of 5 tails), namely the control group and the treatment group. Induction of hypercholesterolemia was performed with a high-fat diet for 7 days. The purple sweet potato ethanol extract was administered sonde in the treatment group with a quercetin dose of 2 mg /kg/day for 14 days and the measurement of LDL cholesterol was performed on days 10 and 24 by the CHOD-PAP method. Data were analyzed by Paired t-test. The results showed that LDL cholesterol level in the treatment group showed that 5 mice had decreased, the mean decrease of 32,49 mg/dl while control group 3 decreasing, mean 0,65 mg /dl. There was a significant difference (p <0.05) on changes in LDL cholesterol levels in the treatment group. Provision of purple sweet potato ethanol extract with quercetin dose of 2 mg/kg for 14 days can decrease LDL cholesterol level of hypercholesterolemia rat. From the results of this study is expected to optimize the utilization of purple sweet potato leaves (Ipomoea batatas (L.) Lam) as a drug for lowering LDL cholesterol.

The development of remote sensing technology allows humans to acquire and process data remotely and temporally. Changes in the flow of the Progo river from the last few years are significant, this can be caused by natural factors and human factors. The influence of the intensity of flow and the level of sedimentation in the Progo river causes a massive flow pattern change in the Progo river body. The data used in this research is Medium Spatial Resolution Satellite Imagery, Landsat 5 satellite imagery acquired in 1995 and Landsat 8 acquired in 2017. Monitoring of changes in river flow pattern is generally done by using the method of terrestrial or conventional measurement, which takes a long time, for that the use of methods and remote sensing data can be used to save time. The method used is multispectral classification approach with maximum likelihood algorithm. The results of extraction using digital classification method (maximum likelihood) resulted in the appearance of flow pattern quickly and representative, so this method is suitable for the purpose of rapid detection of changes in flow pattern. The results obtained from the extraction of the Progo river flow pattern show an intricate river flow pattern with many river rubbers on the image appearance of 1995, whereas in the image extraction results in 2017 the river banks and turns do not look dominant, it shows that erosion and sedimentation activities continue to occur massively.

ZnO nanoparticle was synthesized by a simple hydrometallurgical method using raw material of electric arc furnace dust (EAFD),which is a solid waste in the stainless steel industry. Electric arc furnace dust contains 68.81% Zn in the form of zincite (ZnO) and simonkolleite (H10Cl2O9Zn5). The synthesis was carried out in two main steps, i.e., leaching and alkaline precipitation. In this study, the effect of leaching reagent, leaching temperature, and leaching reagent concentration on the percent extraction of Zn in the leaching process from electric arc furnace dust and the characteristics of the resulting ZnO product were studied. The experimental results showed that leaching reagent of acetic acid gives the highest percent extraction of Zn. The results also showed that the increase of temperature and acid concentration could improve the Zn extraction percentage. At 2M acid concentration, Zn extraction percentage already achieved 100%; hence the process is independent of temperature. The ZnO product has a purity of 96%. The XRD data confirmed the nano sizes of the ZnO product. A B S T R A KZnO nanopartikel disintesis dengan metode hidrometalurgi sederhana menggunakan bahan baku berupa debu tungku busur listrik yang merupakan limbah padat industri baja tahan karat.

Method for estimating the effective data rate in 802.11 channels by using a monitoring algorithm
Authors: Mykhalevskiy Dmytro V.
Published: July 2020

The rapid spread of 802.11 wireless technologies and the emergence of a significant number of networks leads to a large number of negative factors that can significantly impair the transmission characteristics of wireless transmission channels. The aim of this research is to develop a method estimating the effective rate of information transmission in 802.11 channels using a monitoring algorithm to improve the design efficiency of wireless networks. During the study, statistical processing models and methods for averaging research results were used. Novel mathematical models have been developed to estimate the effective rate of information transmission, taking into account monitoring parameters and destabilizing factors for 802.11 wireless channels. Models allow us to estimate the effective rate of information transmission at any location of user device in the coverage area of the network in real-time. The peculiarity of such models is consideration of fluctuations in monitoring parameters, which is estimated by the confidence interval between changing the primary informational parameter to determine the suitability of the channel to transmit any type of traffic. Based on the mathematical models obtained, the provisions of a new method for estimating the effective rate of information transmission in the channel of standard 802.11 were formed using a monitoring algorithm, which has high estimation, ease of implementation, taking into account the maximum possible number of destabilizing factors and possibility of adaptation for any other wireless channel standards.
Antenna performance enhancement using inter-coupling effect reducing mechanisms
Authors: Lema Gebrehiwet Gebrekrstos
Published: July 2020

Recently, thinning an antenna has resulted in attractive antenna radiation characteristics enhancement. This performance enhancement using a thin antenna array is achieved because the inter-coupling effects of the array elements are reduced. Though the thinning both reduces the weight of the antenna and enhances the radiation characteristics, iterative algorithms can further enhance the performance and hence, in this research, an optimizer algorithm and inter-coupling reducing mechanisms are applied. The excitation weights of the individual array elements are thinned by turning some of the elements off while some of the elements are turned on. The purpose of the thinning is to enhance the antenna performances like reduced SLL, high directivity, reduced power consumption and flexible radiation pattern. The SLL attenuation mechanism is applied to reduce the SLL in addition to the SLL reduction using the thinning and beamforming. Hence, in this paper, the three techniques (thinning, beamforming and SLL attenuation) are proposed to be integrated to enhance the antenna radiation characteristics. In general, the proposed combined method has resulted in much better SLL reduction, directivity improvement, and power wastage reduction.

Published: July 2020

The Balinese got acquainted with the Dutch for the first time through Cornellis de Houtman, followed by Cornellis Heemskerck. This introduction expresses friendship with the king Dalem Dalem Bekung at the Gelgel palace and continues to ask for permission to trade. It turned out that he got approval from the king Dalem Bekung. This atmosphere changed in the 19th century where the Dutch wanted to dominate Bali so that there was resistance from the kings in Bali such as: the Buleleng War, Jagaraga War, Kusamba War, Banjar War, Puputan Badung War and finally Puputan Klungkung War. This resistance continued under the leadership of I Gusti Ngurah Rai. To strengthen his troops, the way to do this was to seize weapons from the Japanese hands, by storming their forces throughout Bali on December 13th, 1945. This attack was a failure because it had been known in advance by the Japanese army. Then I Gusti Ngurah Rai and his friends went to Java to ask for weapons and report the situation in Bali to the leaders in Java. On April 3rd, 1946 I Gusti Ngurah Rai and his friends returned to Bali. During this trip there was a battle in the Bali Strait which caused the death of Cokorda Rai Gambir and Cokorda Dharma Putra, while Cokorda Oka Sudarsana and 2 (two) men who were supported were taken to Gilimanuk. The journey continued by I Gusti Ngurah Rai on April 4th, 1946 where landed at Yeh Kuning. In order for the struggle to continue the leaders sought weapons by making their own and carrying out attacks on NICA posts in Bali. Although the warriors' possessions are limited, they last long enough.

MEMBANGUN ETOS DAKWAH DALAM KELUARGA
Authors: Chairawati Fajri
Published: July 2020

Etos dakwah dalam bahasa yang sederhana dapat diartikan dengan semangat dakwah. Semangat dakwah ini harus dibangun dan dipupuk dengan kokoh terlebih dahulu dari dasarnya yakni keluarga. Keluarga yang terdiri dari orang tua dan anak-anak adalah suatu lembaga dakwah dalam lingkup kecil. Meskipun kecil, namun amat menentukan baik buruknya nasib suatu bangsa. Di dalamnya orang tua berperan sebagai juru dakwah yang mengajak madâ€™unya (dalam hal ini anak-anaknya) untuk ber amar maâ€™ruf nahi munkar. Jika keluarga baik, masyarakat secara keseluruhan akan ikut baik, dan jika keluarga rusak, masyarakat pun ikut rusak. Bahkan keluarga adalah miniatur umat yang menjadi sekolah pertama bagi manusia dalam mempelajari etika sosial yang terbaik.

Accuracy of time is very closely related to Islamic law, a lot of worship related to time, such as prayer times, breaking fast and ruling. Without a standard time accuracy, worship can not be done perfectly. The clock is a marker of time that makes it easy for Muslims to carry out worship and social activities. Until now there has been no clock that can survive accuracy with a long time, meaning that all clocks must be calibrated within a certain time span. The time standard for clock calibration is the Atomic Clock time that is on the GPS or on the link http://ntp.bmkg.go.id/Jam.BMKG controlled by Badan Meteorologi Klimatologi dan Geofisika (BMKG). This study tries to find the accuracy of mosque hours and the type of clock used in mosques in Lhokseumawe City by using the method of observation and documentation of 20 mosques selected as samples in the study. The results of observation and documentation show that all mosques (100%) in Kota Lhokseumawe have used the clock as a timemarker, 12 mosques, or 60% of the mosque has been using a digital clock with accuracy of 50% in accordance with the standard and 35% analog clock in accordance with a clock standard observer BMKG.Keywords: Time System, Global Positioning System (GPS), Mosque and Lhokseumawe.

Varicella and herpes zoster are two infectious skin diseases of human that caused by varicella zoster virus, where varicella disease is a primary infection that often infected younger people while herpes zoster disease is a recurrent disease that often infected older people because of reactivation of latent varicella-zoster virus. If the pain caused by herpes zoster after recurrent phase is a appeared then the condition is known as postherpetic neuralgia. This study builds a mathematical model of primary infection (varicella disease) and recurrent infection (herpes zoster disease) developed from the SIR model (Susceptible, Infected, Recovered). The human population is divided into seven subpopulations, namely susceptible, infection, recovered of varicella, herpes zoster and postherpetic neuralgia subpopulation. Stability analysis at the critical point by linearization method gives a critical point 𝑇1 that guaranted to exist and unstable if 𝛼 𝜇(𝛽1+𝜇) 𝐴 , while the critical point 𝑇1 does not have any reqruitment. Stability analysis at the endemic disease-free critical point is represented 𝑇1 that will be unstable if 𝑇2 exist and stable 𝑇1 if 𝑇2 exist. Numerical simulations by simulated to describe such temporary disease-free conditions and an endemic stable conditions.

The eyes is one of the five senses that are very important for humans that are used to see the beauty of nature and interact with the environment properly. If the eyes has a problems or diseases, it will be very severe. One of the disorders in the eye is cataract. Cataract if allowed, it will get worse for the sufferer. Therefore, the accuracy of determining the type and layout of early cataract is very important to prevent the more severe effects of cataract. One way to find out early on the type of cataract is by using the mathematical approach to data mining, namely the K-Nearest Neighbor (KNN) method. The concept of the KNN method is to find the nearest neighbor and choose the majority of the classes in the cluster. In this study, the system classified cataract types based on the symptoms experienced by cataract patients at Anutapura Palu Hospital whose research data was obtained from January 2018-March 2018 which amounted to 170 data. The results of this study indicate the accuracy of the KNN method for 170 data at 91.76% Keywords : Cataract, Classification, K-Nearest Neighbor (KNN)
