Published: April 2021

A surge in the emergence and spread of antimicrobial resistance (AMR) has become a major concern. The indiscriminate use of antibiotics in poultry farming, increased consumption of poultry products containing antimicrobial residues is likely to hasten the development of multidrug resistance in pathogens, as well as in commensal organisms. To substantiate our knowledge on the status of AMR to the Neomycin, Gentamicin, Levofloxacin, Ciprofloxacin, Doxycycline, Sulfonamide, Amoxicillin and Cephalexin, commonly being used in poultry farms in Rajshahi city (Western Part) of Bangladesh a cross sectional study was carried out using conventional Kirby-Bauer disc diffusion technique. We tried to identify sensitivity of the stated antibiotics against bacterial samples obtained from 30 liver samples of live birds out of which 24 were layer and 6 were broiler from 10 commercial poultry farms. In our study, we observed that Cephalexin, Neomycin, Gentamicin and Levofloxacin retain superior antimicrobial potency at the rate of 33.33%, 23.33%, 20%, and 23.33% respectively. Moreover, Levofloxacin started to show quite (70%) to moderate (6.67%) sensitivity and Neomycin (76.67%), Gentamicin (80%) Cephalexin (33.33%) show only quite sensitivity indicating exacerbation of existing antimicrobial resistance through gradually losing their affectivity against microbial infections. On the other hand, during our observation Ciprofloxacin (33.33%), Amoxicillin (20%), Doxycycline (6.67%) and Sulfonamides (3.33%) were found having no sensitivity at all, however, these drugs still being considered as drug of choice for commercial flocks to treat microbial infection. Farmers ‘knowledge, attitudes, and practices regarding the use of antibiotics have to be fully compliant in line with manufacturers’ recommendations to reduce risk to public health. This study was, therefore, conducted to collect baseline data on the regularly used antibiotics in poultry production and to provide a greater understanding of the potential impact of antimicrobial resistance on public health.

Indonesia sebagai salah satu negara dengan penduduk muslim terbesar di dunia sangat akrab dengan Bahasa Arab. Penggunaan Bahasa Arab telah menjadi kebutuhan baik untuk beribadah atau penggunaan dalam percakapan sehari-hari. Salah satunya adalah membaca Al-Quran. Tidak seperti bacaan yang lain, membaca Al-Qur’an memiliki ketentuan khusus yang harus diperhatikan. Ilmu tersebut dinamakan sebagai ilmu tajwid. Salah satu cabang dalam ilmu tajwid adalah Makhraj Huruf, yaitu ilmu yang mempelajari tentang tempat-tempat keluarnya huruf pada waktu huruf-huruf itu dibunyikan. Mempelajari makhraj huruf dapat dilakukan dengan berbagai cara baik melalui guru secara langsung atau melalui media-media yang tersedia salah satunya dengan animasi. Untuk menghasilkan animasi yang akurat dilakukan teknik rotoscoping dan membandingkannya dengan teknik Auto Lip-Sync sehingga menghasilkan perbandingan baik secara teknis maupun kualitasnya. Parameter pengukuran secara teknis dinilai menggunakan tiga aspek, yaitu frame yang dihasilkan, waktu rendering yang dibutuhkan, dan ukuran file yang dihasilkan. Dari perbandingan tersebut menghasilkan kesimpulan bahwa penggunaan teknik rotoscoping menghasilkan animasi yang nautral dan akurat. Sesuai dengan respon pengguna, animasi ini dapat digunakan sebagai media pembelajaran pendamping karena tidak bisa mengganti cara konvensional dalam belajar makhraj huruf.

Показано, что если существуют субкварковые частицы – ритоны, то они вместе с переносчиками фундаментальных взаимодействи и бозоном Хиггса образуют модель фундаментальных частиц из которой образуются частицы Стандартной модели. Из ритонов, которые являются фермионами со спином 1/2, образуются массивные частицы Стандартной модели: кварки, лептоны, а также Z0 и W±-бозоны. Второе и третье поколе-ния кварков и лептонов объясняются как возбуждённые состояния фермионов первого поколения. На основе модели ритонов было предсказано, что нейтрино массивные дираковские фермионы. Из модели ритонов следует, что число частиц и античастиц, т. е. ритонов и антиритонов, во Вселенной одинаково.
Electro-Thermal Characteristics of Hybrid TiO2-SiO2 Nanofluid Coolants in An Electrically-Active System
Authors: Wan Mohamed ‪Wan Ahmad Najmi , Suhaimi Mohd. Azeem , Zakaria Irnie Azlin , Wan Hamzah Wan Azmi
Published: April 2021

Thermal management in an electrically-active system is a challenging engineering branch due to the critical requirement for rapid cooling rates with inhibition of electrical discharge. A Polymer Electrolyte Membrane Fuel Cell (PEMFC) is an example of a system that needs both conditions to be critically fulfilled. The use of conventional deionized water with low electrical conductivity as the cooling fluid ensures insignificant electrical potential losses but large thermal capacities can only be achieved with a significant penalty to the PEMFC system size. Formulation of nanofluid coolants has been highly successful for systems working under normal environments, but research towards new nanofluid coolants for active electrical systems are relatively new. This paper reports a fundamental investigation on the electrical and thermal behaviors of a hybrid 1%v TiO2-SiO2 (at 50:50 ratio) nanofluid dispersed in 60:40 water/ethylene glycol solution. A test bench consisting of a heated rectangular channel combined with continuous electrical supply at 0.7 V and 3 A nominal current was developed to simulate the operating conditions of a PEMFC stack cooling. The test variables are the heater temperature and Reynolds number (300 to 700) of the coolants. The cooling profiles and changes in electrical properties of the system and coolants were analyzed. Significant increase in cooling rates were achieved by the hybrid nanofluids (200% to 250%) compared to water and water/ethylene glycol coolants. The electrical analysis indicates that the power drop is low for water and water/ethylene glycol but drops rapidly in an exponential profile (between 15% to 45%) which also leads to a visible increase in the electrical conductivity of the nanofluids coolants. As such, further research is needed to reduce the apparent electrical discharge problem before a suitable nanofluid coolant can be developed for electrically-active systems.

Dielectric Study of PVC-LiF Composites Films
Authors: Ahmad A. Hasan
Published: April 2021

PVC-LiF composites films with different lithium fluoride (LiF) concentrations (0, 30, 50, and 70 weight %) were prepared by using the casting method. This research deals with the investigation of dielectric properties for PVC-LiF composite films as a function of frequency and temperature in the ranges of 100 to 107 Hz and 293 - 370 K, respectively. The A.C activation energy values estimated from Arrhenius equation were 0.03820, 0.3174, 0.2009, and 0.1845 eV for the different PVC-LiF films with different LiF concentrations, respectively.  It was found that the activation energy decreases by increasing LiF concentration and frequency. The exponent (s) showed a progressive increase with LiF for PVC-LiF films, while it showed a non-systematic sequence with the increase of temperature. The dependence of the dielectric constant (εr) and dielectric loss (εi) on temperature and frequency was investigated for PVC-LiF films with the different LiF concentrations. The dielectric spectrum showed a strong dispersion when LiF was added to the polymer matrix (PVC) in the whole range of frequency and temperature. The results were interpreted in terms of structural differences caused by the effect of thermal treatment.

Published: April 2021

This study investigates load frequency control based generalized extended state observer (GESO) for interconnected power systems subject to multi-kind of the power plant. First, the mathematical model of the interconnected power system is proposed based on the dynamic model of thermal power plant with reheat turbine and hydropower plant. Second, the GESO is designed to estimate the system states and disturbances. In addition, the problem of unmeasurable system states in the interconnected power network due to lack of sensor has been solved by using the proposed load frequency control based GESO. The numerical experiments are carried out by using MATLAB/ SIMULINK simulation. The simulation results point out that the proposed control approach has the capacity to handle the uncertainties and disturbances in the interconnected power system with better transient performances in comparison with the existing control approach. The relevant dynamic models have already been used for the simulation of the physical constraints of the governor dead band (GDB) and generation rate constraint (GRC) effect in the power plants. It is evident that the robustness of the suggested controller in terms of stability and effectiveness of the system. This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

Penelitian ini menggunakan regresi panel berdasarkan Fully Modified Ordinary Least Square (FMOLS) dan Dynamic Ordinary Least Square (DOLS).  Hasil penelitian menunjukkan bahwa pertumbuhan ekonomi berdampak negatif, sedangkan upah minimum kabupaten/kota berdampak positif terhadap pengangguran terbuka. Peningkatan pertumbuhan ekonomi mendorong penurunan pengangguran terbuka, sedangkan kenaikan upah minimum kabupaten diikuti oleh kenaikan tingkat pengangguran terbuka. Sementara  itu, modal manusia tidak berpengaruh pada tingkat pengangguran terbuka akibat rendahnya rata-rata lama sekolah. Untuk itu, pemerintah perlu meningkatkan sumber daya manusia melalui wajib belajar 12 tahun.

Rotator Cuff–Related Shoulder Pain: Is It Time to Reframe the Advice, “You Need to Strengthen Your Shoulder”?
Authors: Powell Jared K. , Lewis Jeremy S.
Published: April 2021

Synopsis

Progressive resistance exercise, in isolation or in combination with other noninvasive therapies such as therapeutic touch, is the first-line approach to managing nontraumatic rotator cuff–related shoulder pain (RCRSP). Resistance exercise may be effective for people with RCRSP secondary to improving mechanical features of the shoulder, including strength, kinematics, and muscle timing and activation. However, strength gains are often small and clinically unimportant when measured during clinical trials. In this Viewpoint, we argue that clinicians should (1) continue to prescribe resistance exercise when managing RCRSP, and (2) embrace the broad biological mechanisms underpinning the efficacy of resistance exercise. Any benefit is governed by more than simple mechanical changes. The clinical message must go beyond the idea that the patient's weak, deconditioned, or frail shoulder is the basis of his or her pain, and all the patient needs to do is to get strong.

Authors: Sami Abdul Hanan , Naveeda Naveeda
Published: April 2021

Present study aimed at investigating the association between personality traits, perceived social support and depressive symptoms in adolescents. Through convenient sampling, total 302 students (110 males and 192 females) were recruited from different universities of Rawalpindi and Islamabad. The age range of sample was 18-25 years. In present study, The Big Five Inventory- Short Version (BFI-S) (Gerlitz & Schupp, 2005), The Multidimensional Scale of Perceived Social Support (MSPSS) (Zimet et al., 1988), and Depression, Anxiety and Stress Scale (DASS-21) (Lovibond & Lovibond, 1995) were used to access personality traits, perceived social support and depressive symptoms. Findings of the present study showed a significant positive relationship between neuroticism and depressive symptoms. However, extraversion, conscientiousness and perceived social support showed significant negative association with depressive symptoms. According to regression analysis, neuroticism is a positive while, perceived social support is significant negative predictor of depressive symptoms in young adolescents. Furthermore, findings of present study may assist in identifying the personality traits at risk of experiencing depression.

Parental involvement had benefit for the education of elementary children. Yet, knowing parental efficacy was important factor to do such involvement.  The purpose of this study was to design and examine a practical, valid, and reliable parental efficacy scale for measuring parents’ capabilities to involve in elementary education. A total of 402 parents of elementary children participated in this study, consisting of 114 fathers (28.36%) and 288 mothers (71.64%). They were selected randomly from 10 elementary schools and fulfilled informed consent showing they participated voluntarily in the study. A Parental Efficacy Scale which had been designed was tested for its practicality, validity and reliability. This self-report instrument asked parents to respond 67 items containing six aspects, namely their belief to be able parenting children, communicating with the school, helping children learn at home, becoming school volunteers, making decisions, and collaborating with community. The results showed that the scale fulfilled all of three requirements in all six aspects.

Objetivo: Descrever como é caracterizada a violência obstétrica na produção científica nos últimos 12 anos. Métodos: Trata-se de um estudo de revisão integrativa da literatura no qual foram utilizadas as bases de dados LILACS, Scielo e PUBMED para a busca e seleção de artigos em um corte temporal de 12 anos. Resultados: Após leitura e análise dos artigos considerados elegíveis foram definidas as seguintes categorias de resposta que guiaram a análise dos dados coletados: “Procedimentos desnecessários e sem consentimento”; “Intervencionismo e maus tratos durante o parto”; “Abuso físico, emocional e sexual por parte do parceiro íntimo”. Um dos autores pesquisados detalhou a violência obstétrica descrevendo-a como: “cuidado não consentido, direito à informação; cuidado não confidencial; abuso verbal; abandono do cuidado; cuidado discriminatório; e abuso físico”, sendo assim definida a categoria “supressão de direitos e de cuidados”. Considerações finais: A análise dos artigos consultados aponta para um conceito de violência obstétrica relacionado a realização de procedimentos sem o consentimento da gestante em qualquer situação onde não há previsão legal para sustentar a execução da ação de saúde.

Published: April 2021

Gunung Tugel Disposal Site (GTDS) is one of the final land disposal sites established in 1983 in the Banyumas Regency, and it operates with an open-dumping system. In this system, the base of the disposal site is neither coated with an impermeable layer nor equipped with leachate collection and drainage channels, for which leachate can percolate through the soil and pollute groundwater. In March 2016, GTDS was closed because its capacity had been exceeded. The closure of GTDS was not followed by appropriate waste and environmental management, prompting the formation of leachate that can contaminate the environment, particularly groundwater. This research set out to identify the leachate quality of GTDS, assess the groundwater quality, and determine the groundwater quality status around the disposal site. It employed a field survey and mapping to plot and display the groundwater well points in the study area, laboratory analysis to identify the groundwater quality, and pollution index calculation to determine the groundwater quality status. The groundwater samples were tested in the laboratory for their physical (turbidity and TDS), chemical (pH, COD, BOD, iron (Fe), cadmium (Cd)), and biological properties (total coliform). The results showed that the cadmium (Cd) levels in several groundwater well points had exceeded the quality standards. Based on the analysis and calculation results, the groundwater quality status in the study area is mildly contaminated, with the pollution index ranging between 2.571 and 4.099.

Samosir is the islands that emerge and standing upon on Toba Caldera after it’s the last eruption at 74.000 years ago. Samosir Island known as the caldera floor that uplifts parallel with Toba’s caldera flooding. In this study, we have observed an outcrop in Tumutuk, Samosir Island that hypothesized as a lacustrine deposit, and we found a paleosoil layer that might give more answers about the geological process in this area at the past time. Based on this outcrop, we described it, followed to measure its stratigraphy section, and took representative samples from the paleosoil layer, then observed the samples under the stereo-microscope as polish rock section, in normal light & negative images. As the result we identify several features of paleosoil & its sedimentary grain that shown this paleosoil layer, two events of the volcanoclastic deposits flown, and exposed two-time, and forming soil, it may form in the shallow swamp in a lacustrine environment, coincide with caldera flooding and caldera floor uplift event.

Watukumpul is an area that is prone to landslides, so determining the soft layer thickness is very important to identify the landslide potential. The soft layer thickness can be estimated using microtremor signal measurements which analyzed using the Horizontal to Vertical Spectral Ratio (HVSR). In this study,we measured microtremor signal of 33location around Watukumpul, Pemalang, Central Java area to determine soft layer thickness. Micretremor signal was analyzed based on theHVSR method using Geopsy software and follow the standard of the Sesame Europan Project. The results of the HVSR method are the HVSR curve that fulfills the reliable curve standard. HVSR curve shows that the dominant frequency of soft layer ranges from 1.36 – 7.62 Hz and the amplification values ranges from 9.00 – 41.45. The soft layer thickness value in the study area ranges from 17.58 - 103.60 meters. The high landslide potential area are located at W7, W8, W18, W30 and W32 where has thin soft layer and high soil slope.
