Effect of Drying Method and Hydrothermal Treatment on Physicomechanical Properties of Parboiled Rice
Authors: Mahfeli Mandana , Zomorodian Aliasghar , Zarein Mohammad
Published: November 2020

Rice grain was obtained from milled paddy, in which the husk and bran are removed. During the milling process, rice varieties having inherent poor milling quality or those have been processed under unfavorable conditions, break and so their head rice yield (HRY) decrease. Parboiling is one of the hydrothermal postharvest treatment before drying and milling processes. After parboiling, the grains become stronger and breakage of rice is very much reduced during milling, leading to often a remarkable increase in the HRY. In this study the paddy was soaked in hot water (70 °C) for 1 h and drained, then steaming was done at four periods (0, 5, 10 and 15 minutes) at atmospheric pressure. Drying process was carried out using two driers techniques, solar and continuous, at three inlet air temperature to the chamber dryer of 35, 40 and 45○C. Results revealed that the effects of drying air temperature and steaming time showed a significant effect on HRY and broken kernels for Hashemi rough rice cultivar (p<0.05) in continuous dryer. In both drying techniques the higher HRY performance was appeared at 35○C drying air temperature and 10 min steaming time. It was observed that dried kernels in continuous dryer were stronger (more bending strength) than those dried in the solar dryer and had a higher rate of HRY during subsequent processing operations. It was proved that increasing the steaming time to a safe level caused a reduction in broken kernels which was associated with higher HRY.

BackgroundDifferent surgical approaches used in total hip arthroplasty (THA) include a direct anterior approach (DAA), anterolateral approach (AL), and posterolateral approach (PL). However, the acetabular cup position varies according to surgical view, surgical table, and patient position for each approach. This study is aimed to compare acetabular cup position in THA under different approaches, including surgical time, blood loss, and postoperative complications.MethodsBetween Jan 2017 and Dec 2018, 231 patients who underwent THA (64 DAA, 96 AL, and 71 PL THAs) were analyzed retrospectively. Intraoperative blood loss, operation time, preoperative and postoperative WOMAC score, cup anteversion, inclination angle, and postoperative complications were analyzed.ResultsDAA showed longer operation time and more blood loss, but shorter hospital stays. The cup was found in the safe zone for 97% of DAA patients, 74% of AL patients, and 56% of PL patients. PL showed the highest complication rate (9.9%), followed by DAA (3.1%) and AL (1%). There was no statistically significant difference in preoperative and postoperative WOMAC scores. ConclusionTHA by DAA using a special table is a more reliable procedure to achieve safe cup position. Although DAA showed fewer outliers in cup position, it resulted in longer operation time and greater blood loss compared to other groups.Trial registration: Retrospective study

Authors: Schulte Wibke , Aliyeva Ilhamiyya , Knoop Michael , Pratschke Johann
Published: November 2020

Background: The surgical creation of an artificial opening of the bowel, called ostomy, can become necessary for very different causative diseases. A special subgroup are ostomies created during emergency surgery, which pose particular challenges to affected patients. This work is dedicated to their detailed characterization.Methods: A retrospective analysis of surgical ostomy creations at an acute care university hospital and an online survey for patients with an ostomy were performed and evaluated.Results: In our study, about one third of all ostomies were created during emergency surgery (37.4%). Compared to patients who received an ostomy during elective surgery, emergency patients had a higher ASA score and diagnoses requiring acute surgical care. Patients undergoing emergency surgery were more likely to have inadequate preoperative medical education (60% vs. 33.3%, p=0.029), and rarely received preoperative ostomy marking (4% vs. 79.2%, p<0.001). Emergency patients underwent minimally invasive surgery less frequently (26.8% vs. 51.3%, p=0.001), and showed a higher rate of peristomal wound dehiscence (9.9% vs. 2.5%, p=0.028). Accordingly, emergency ostomies often resulted in an overall reduction in postoperative quality of life.Conclusion: Ostomies are often created during emergency surgery under suboptimal perioperative conditions. This results in higher complication rates and negative physical and psychological effects. Therefore, intensive interdisciplinary care is essential to provide the best possible care for patients affected by these artificially created intestinal outlets.

Published: November 2020

BACKGROUNDː The Epidermolysis Bullosa (EB) is a rare genetic disease associated with blistering skin caused by minimal trauma. Because of its exposed position and its continued use in daily activities, the hand is constantly at risk of microtrauma and is therefore one of the organs most affected by the disease with highly disabling deformities that represents a challenging field in hand surgery practice.METHODSː The Authors present their experience in the microsurgical treatment of pseudosyndactylies comparing the classic dressing with vaseline gauze with our innovative “glove protocol” using Integra® dermal regeneration template. The endpoints analyzed were: healing times, hospital stay time, discomfort for the patient, free-recurrence interval, follow-up range and major complications.RESULTSː A total of 34 procedures were performed on 24 EB patients with hand deformities. Compared with the dressing with vaseline gauze, microsurgery followed by application of dermal regeneration template gloves allowed a significant reduction of hospital stay, healing time, and dressing pain as well as an increased recurrence-free interval.CONCLUSIONSː The microsurgical approach followed by our new protocol described in the study has been beneficial in providing consistent and successful long-term results for these patients.

Published: November 2020

Background: Osteoporosis and fractures are important aromatase inhibitor (AI) related adverse events in postmenopausal women with hormone receptor positive breast cancer. An incremental increase of pentosidine is associated with a deterioration of bone quality. In this study, pentosidine was evaluated in postmenopausal breast cancer patients receiving AIs.Methods: Fifty Japanese postmenopausal breast cancer patients receiving AIs were retrospectively evaluated. Sixteen patients were given a bone modifying agent (BMA) concomitant with AIs. Changes of pentosidine, bone turnover markers and bone mineral density (BMD) before and after 12 months of AI therapy were compared between BMA administered patients (BMA group) and a non-BMA group. These factors were assessed by BMA groups using chi-square of categorical variables and t-test for continuous variables.Results: The median age of the subjects was 67 years, and 21, 23 and 6 subjects were classified as normal, bone loss and osteoporosis, respectively. There was no significant difference between pentosidine low and high groups in regard to age, height, weight, BMD of femoral neck and lumbar spine, and bone turnover markers including TRACP-5b and BAP. In the non-BMA group, pentosidine was increased in 18 cases (53%), and the average change of pentosidine was 21.5% (95%CI; 0.23 to 42.7%, p=0.048). In the BMA group, pentosidine was increased only in 2 cases (13%), and the average change of pentosidine was -16.6% (95%CI; -30.6 to -2.6%, p=0.023). There was a significantly lower proportion of pentosidine-increased cases (p=0.0065) and decrease of pentosidine (p=0.021) in the BMA group compared to those in the non-BMA group.Conclusions: Pentosidine was increased with AI, however, BMA inhibits an AI-induced increase of pentosidine in postmenopausal breast cancer patients.

Published: November 2020

Background: Fetal sex is known to modify the course and complications of pregnancy, with recent evidence of sex-differential fetal influences on the maternal immune and endocrine systems. In turn, heightened inflammation and surges in reproductive hormone levels associated with pregnancy and parturition have been linked with the development of perinatal depression. Here, we examined whether there is an association between fetal sex and maternal depression assessed during the prenatal and postnatal periods. Methods: The study included two multi-ethnic, prospective pregnancy cohorts that enrolled women from prenatal clinics in the Northeastern United States between 2001 and 2018. Maternal depressive symptoms were measured during the prenatal and postnatal periods using the Edinburgh Postpartum Depression Scale (EPDS) and newborn sex was reported by the mother following delivery. We used logistic regression to examine associations between fetal sex and maternal depressive symptoms (EPDS>10) during the prenatal period only, postnatal period only, or both periods versus no depressive symptoms during either period. We considered both unadjusted models and models adjusted for a core set of sociodemographic and lifestyle variables. Results: In adjusted models using PRISM data (N=528), women pregnant with a male versus female fetus had significantly greater odds of depressive symptoms during the postnatal period compared to women without depressive symptoms during either period (odds ratio [OR] = 5.24, 95% confidence interval [CI] = 1.93, 14.21). The direction of results was consistent in the ACCESS cohort, although the findings did not reach statistical significance (OR = 2.05, 95% CI = 0.86, 4.93). Significant associations were not observed in either cohort among women with prenatal symptoms only or women with prenatal and postnatal symptoms. Conclusions: Male fetal sex was associated with the onset of depressive symptoms during the postnatal period.

Authors: Kaur Navjeet , Kaushal Jyotsna , Mahajan Pooja , Srivas Arun Lal
Published: November 2020

Most of the dyes are carcinogenic and mutagenic in nature. Plants are potential candidates to remediate textile dye wastewater from contaminated sites. The present study aimed to screen potential plant species for removal of synthetic dye solution of triarylmethane dye Methylene Blue (MB) and diazo dye Congo Red (CR). The six plants selected for screening are Trachyspermum ammi (T. ammi), Tagetes erecta (T. erecta), Hibiscus rosa-sinensis (H. rosa- sinensis), Chrysanthemum indicum (C. indicum), Bryophyllum fedtschenkoi (B. fedtschenkoi), and Catharanthus roseus (C. roseus). The phytotreatment of dyes was done up to 40 h for two different concentrations of dyes i.e. 10 and 20 mg L−1. Among screened plant species, the maximum decolorization was obtained from T. ammi followed by B. fedtschenkoi. Both of these plant species showed active growth even after the phytoremediation process. T. ammi decolorized the MB dye 99% (10 mg L−1) and 86% (20 mg L−1) while the decolorization of the CR dye solution was up to 95% (10 mg L−1) and 84% (20 mg L−1). T. ammi found to have maximum potential among screened plants for the removal of MB and CR dye from synthetic dye solution and can be used for phytoremediation of wastewater contaminated with synthetic dyes.

Authors: Kim Hosu , Kim Tae Kyong , Yoo Sukha , Kim Jin-Tae
Published: November 2020

Background A fluid warmer can prevent hypothermia during the perioperative period. This study evaluated the heating capabilities of Hotline and Barkey S-line under different flow rates and initial fluid temperatures, as well as after the extension line installation. Methods We measured the temperature of a 0.9% sodium chloride solution at the fluid warmer outlet (TProx) and the extension line end (TDistal) with three different initial fluid temperatures (room, warm, and cold) and two flow rates (250 ml/hr and 100 mL/hr). Results At a 250 ml/hr flow rate, the TProx and TDistal values were observed to be higher in Hotline than in S-line when using room-temperature or cold fluid. Administering of the warm fluid at the same flow rate significantly increased the TProx and TDistal values in S-line more than the cold and room-temperature fluids. At flow rates of 100 ml/hr, TDistal values were significantly lower than TProx values in both devices regardless of the initial fluid temperature. Conclusions Hotline outperformed S-line for warming fluids at a high flow rate with cold or room-temperature fluids. Administering warm fluid in S-line prevented a decrease in the fluid temperature at a high flow rate. However, at a low flow rate, the fluid temperature significantly decreased in both devices after passing through an extension line.

Published: November 2020

Background: Sex differences in obesity and related metabolic diseases are well recognized, however, the mechanism has not been elucidated. Gut microbiota and its metabolites may play a vital role in the development of obesity and metabolic diseases. The aim of the present study was to investigate sex differences in gut microbiota and its metabolites in a high-fat-diet (HFD) obesity rats and identify microbiota genera potentially contributing to such differences in obesity and non-alcoholic fatty liver disease (NAFLD) susceptibility.Methods: Sprague–Dawley rats were divided into four groups (eight animals per group): (1) male rats on a normal diet (MND), (2) male rats on HFD (MHFD), (3) female rats on a normal diet (FND), and (4) female rats on HFD (FHFD). Body weight, liver pathology, gut microbiota and short/medium chain fatty acids in colon contents were compared between different sexes.Results: HFD induced more body weight gain and fat storage in female rats, however, lower hepatic steatosis in FHFD than in MHFD rats was observed. When considering gut microbiota composition, FHFD rats had lower microbiome diversity than MHFD. A significant increase of Firmicutes phylum, along with Bilophila and Blautia genus was detected in MHFD rats, as compared with FHFD, which showed increased relative abundance of Murimonas. Moreover, propionic and lauric acid levels were higher in FHFD than those in MHFD rats. Conclusions: HFD induced sex-related alterations in gut microbiome and fatty acids. Furthermore, the genus Bilophila, Blautia and Murimonas might contribute to sex differences observed in obesity and NAFLD susceptibility.
How to GAN event subtraction
Authors: Butter Anja , Plehn Tilman , Winterhalder Ramon
Published: November 2020

Subtracting event samples is a common task in LHC simulation and
analysis, and standard solutions tend to be inefficient. We employ
generative adversarial networks to produce new event samples
with a phase space distribution corresponding to added or subtracted
input samples. We first illustrate for a toy example how such a
network beats the statistical limitations of the training
data. We then show how such a network can be used to subtract
background events or to include non-local collinear subtraction
events at the level of unweighted 4-vector events.

Ações judicias envolvendo medicamentos oncológicos são uma realidade crescente no Brasil, gerando grandes impactos orçamentários sobre a gestão pública. Devido ao alto valor empregado nesses medicamentos, bem como à alta complexidade que envolve o tratamento, é necessária uma análise técnica criteriosa para que se garanta a eficácia do tratamento, associada a um emprego justificado do dinheiro público. O objetivo do presente estudo foi analisar o perfil das demandas judiciais atendidas no setor de oncologia do HE-UFPel, bem como o impacto financeiro que estas representaram aos cofres públicos. De janeiro de 2017 à agosto de 2019, o setor de oncologia atendeu a 146 decisões judiciais, representando um gasto total de aproximadamente de R$ 11.439.544,00 aos cofres públicos. Os medicamentos mais demandados judicialmente, por ordem decrescente, foram: bortezomibe, abiraterona, bevacizumabe, trastuzumabe, rituximabe e pazopanibe; sendo mieloma múltiplo, câncer de próstata, câncer colorretal, câncer de mama e renal os acometimentos mais prevalentes. Evidencia-se que, para a gestão pública, os efeitos são negativos uma vez que geram desajustes orçamentários e financeiros. O presente trabalho aponta problemas envolvidos no processo, bem como estratégias possíveis de serem aplicadas, a curto e longo prazo, pelos entes federativos, judiciários e assistenciais; de forma a minimizar as consequências negativas da judicialização ao mesmo tempo em que buscam garantir ao cidadão todos seus direitos previstos em lei.

O objetivo do presente estudo foi verificar a qualidade assistencial prestada às pessoas vivendo com HIV (PVHIV), oferecida por uma Unidade Especializada (UE) sob gestão do município e um Serviço Especializado (SE) sob gestão federal, situados em município do interior do Rio Grande do Sul. O questionário Qualiaids busca avaliar e monitorar a organização dos serviços de saúde do SUS que acompanham o tratamento da infecção pelo HIV. O acesso aos dados referentes às respostas dos serviços UE e SE ao questionário aplicado no ano de 2017, foi obtido após solicitação formal a Equipe de Pesquisa Qualiaids. Desta forma, foi realizado um estudo descritivo, verificando as respostas relacionadas a cada dimensão. Foram selecionados os indicadores que qualificam o atendimento prestado aos pacientes com HIV, verificando quais os aspectos com maior dificuldade em cada serviço, sem ter como objetivo a comparação entre os mesmos, pois estão em níveis diferentes na rede de atenção. Ambos os serviços destacaram como dificuldade gerencial o acúmulo de função e a pouca integração entre atenção básica e serviço especializado. A UE apresentou 13,9% de faltas nas consultas médicas agendadas e o SE 19%,com assistência satisfatória, principalmente com foco na adesão a terapia antirretroviral (TARV), fator importante para atingir as metas nacionais 90-90-90 (diagnóstico, tratamento e supressão viral). A avaliação sistemática da adesão a TARV associado ao compartilhamento do cuidado são fatores fundamentais para a integralidade da atenção à PVHIV.

Published: November 2020

The wake of a single-box girder in sinusoidal oscillating flow is studied by three-dimensional large-eddy simulations (3D LES). The validation of numerical simulation is verified by active-controlled wind tunnel experiments. The mean and fluctuating velocity, as well as the vortex shedding distance in the sinusoidal oscillating flow are discussed. The fluctuating velocity near the wake increases with the increasing oscillation amplitude, however it is distribution period independent of oscillation amplitude. The vortex shedding distance decreases as the oscillation frequency increases, meanwhile, the oscillation amplitude has no effect on it.
Vibration technique for monitoring termite induced degradation in trees
Authors: Jadhav Prakash
Published: November 2020

Termites infestation is a big problem for trees. It is also very difficult to find the trees with termite damage. It is essential to find the trees with initial level of termite damage so that the trees can be treated with suitable available treatments. It is proposed here a new technique using vibration analysis which can detect the termite damage inside the tree trunks by just performing very simple vibration experiment. This method is cheap, efficient and can potentially save large number of trees from dying due to termite infestation. By performing laboratory level experiments, this research proves the feasibility of this simple technique of damage detection in trees.

In order to explore the feasibility of the new type of armor against projectile penetration, a steel plate tube array composite armor was designed, and its effectiveness against projectile penetration was studied by numerical simulation. The results of simulation vividly reproduce the physical and mechanical processes of composite armor structure, such as deformation and breakage, penetration failure, and stress wave propagation under the impact of projectile. The time history characteristics of projectile residual velocity were accurately captured. The influence of key factors, such as the number of tube array layers, array combination form and projectile impact position on the damage mode of the composite armor structure was obtained. The related results can provide important support and scientific basis for the optimal design and accurate evaluation of the new composite armor.

Pandemic, COVID-19 came into existence in late December 2019 at Wuhan, China. To
cure the COVID-19 and reduction in morbidity, the development of potential vaccines and antiviral
drugs may take months or years. To reduce the pressure on healthcare infrastructure, traditional medicines
may use as an alternative measure. The rationale of the current study was to provide the pharmacological
details of Ayurvedic herbs viz. Alstonia scholaris L., Picrorhiza kurroa, Swertia chirata
and Caesalpinia crista w.r.t. symptoms of COVID-19. The available information on the ethnomedicinal
uses, phytochemistry, and pharmacology was collected via a library and electronic searches in
Sci-Finder, Pub-Med, Science Direct, Google Scholar for the period of up to 31 August 2020. The
major symptoms of COVID-19 include pro-inflammation, inhibition of Angiotensin-Converting Enzyme
II (ACE2) and reactive oxygen species. A literature search revealed that all herbs under study
are potent against two or more symptoms of COVID-19. All four Ayurvedic herbs viz. Alstonia
scholaris L., Picrorhiza kurroa, Swertia chirata and Caesalpinia crista may be a good option, including
other traditional drugs during the outbreak of COVID-19. In-depth experimental, preclinical and
clinical studies are required in the future to develop a potent drug against COVID-19.

Objetivo: Avaliar a influência do sexo e das linhagens de camundongo (NIH e BALB/c An) no TGPC da VPCI de referência, da toxina pertussis (TP) e de 36 amostras de vacinas DTP. Método: Dez animais de cada sexo e linhagem foram pesados e, em seguida, inoculados intraperitonealmente com 0,5 mL/camundongo da VPCI de referência, de TP (0,25-2,0 μg/animal) ou de vacinas DTP. Grupos-controle para VPCI e TP foram inoculados com PBS e para vacinas DTP empregou-se o cloreto de sódio 0,9% com 100 ppm de timerosal. O teste é satisfatório se não ocorrerem mortes, se o ganho de peso médio (GPM) dos animais inoculados no 3° dia for superior ao inicial e no 7° dia o GPM for igual ou maior que 60% do controle. Os resultados do TGPC foram avaliados pelos critérios em vigência e pelo proposto no 7° dia, no qual o limite inferior do intervalo de confiança de 95% do GPM seja igual ou maior que 60% do controle. Resultados: A VPCI de referência foi satisfatória em fêmeas NIH e BALB/cAn e insatisfatória em machos de ambas as linhagens considerando-se ambos os critérios. O TGPC em ambas as linhagens e sexos revelou baixa sensibilidade na detecção do efeito da TP isolada (0,25-2,0μg/camundongo). As vacinas DTP foram satisfatórias em camundongos NIH de ambos os sexos e em fêmeas BALB/cAn, porém o resultado foi insatisfatório para 14,0% das vacinas DTP em machos BALB/cAn por ambos os critérios. Conclusões: O TGPC de vacinas DTP em camundongos fêmeas de ambas as linhagens deve ser considerado, pois evidenciou-se que fêmeas NIH e BALB/cAn são adequadas para a realização do TGPC. A adoção do critério proposto no 7° dia deve ser estimulado por aumentar a sensibilidade e precisão do TGPC.

Weeds in sugarcane have negatively affected the sugar yield rate. Several approaches have been carried out to overcome the weeds, including the usage of diuron as synthetic herbicide. However, the long-term usage of diuron is known to have a negative effect leads to the production of 3,4- Dichloroaniline responsible for soil leach and bioaccumulation. Therefore, this study aimed to find a potential natural herbicide. By mimicking the diuron's mode of action which inhibits the process of photosynthesis through blocking the Photosystem II protein D1 (psbA) of the weeds, fourteen compounds as potential candidate bioherbicides were virtually docked by PyRx v0.9.5 software to the specific site. Three important species of the weeds were chosen including Eleusine indica, Praxelis clematidea, and Momordica charantia. The binding affinity score was further calculated and ranked to screen the top six compounds as bioherbicide candidates. Interaction of each complex and the biological activity prediction were then performed by Discovery Studio software and PASS server, respectively. Aurachin P, Aurachin A, and Cyanobacterin were placed in the top ranked compounds with high binding affinity score around -6 to -9 kcal mol-1 toward the psbA. The amino acid interaction involved in the complex shows 50-90% similar to the control, psbA and diuron complex. Besides, the biological activity prediction of Aurachin P, Aurachin A, and Cyanobacterin exhibits the terms related to the inhibition of photosynthesis process via enzymatic pathway. Thus, the active compounds might have inhibition action in the photosynthesis process and control  the weeds in sugarcane.

Estrategias audiovisuales, educomunicativas y recreativas para la transformación social y la creación de vínculos comunitarios
Authors: Valencia-Calero Victoria E. , Hernández Ortiz Juan Camilo
Published: November 2020

Este artículo retoma el concepto de obras expresivas audiovisuales comunitarias y su estrecho vínculo con la recreación. Este estudio parte de algunos resultados del proyecto de investigación. El objetivo es visibilizar la importancia de desarrollar procesos educomunicativos de mediano y largo aliento en los que no solo se vinculen lenguajes audiovisuales, sino también otras formas de expresión lúdico-creativas. El enfoque metodológico del proyecto de investigación fue cualitativo, basado en la observación profunda y la descripción densa de la etnografía clásica, así como en la etnografía audiovisual y en la etnografía virtual. Los principales hallazgos, desde la perspectiva de la comunicación basada en las mediaciones, es que las OEAC tienen lugar en el centro mismo de las comunidades, en los usos, las relaciones y los vínculos que se construyen en los procesos de comunicación. Además de funcionar socialmente como mediaciones en el sentido desarrollado por Martín-Barbero (1991), están conformadas por mediaciones semióticas o lenguajes lúdico-creativos (Mesa, 2004). En conclusión, se considera que las OEAC abren posibilidades de transformación social porque desarrollan procesos que trascienden las películas, reconocen los aspectos sociohistóricos, fortalecen la identidad colectiva y hacen posible una fluida relación entre sujetos y contextos.
Transformative Learning in the Art Museum: A Methods Review
Authors: Chisolm Margaret S. , Kelly-Hedrick Margot , Stephens Mark B. , Zahra Flora Smyth
Published: November 2020

Abstract: Clinical educators are continually seeking innovative methods and settings for teaching. As such, they have increasingly begun to use art museums as a new educational space in which to build clinically-relevant skills and promote learners’ professional identity formation. Art museum-based pedagogy can be understood through the framework of transformative learning theory, which provides an account of how adults learn through experience. In this article, the authors apply this theory to art museum-based teaching and offer a practical overview of art museum-based activities, highlighting three exemplars: visual thinking strategies, personal responses tour, and group poems. This toolbox of art museum-based teaching methods provides a launching pad for educators and learners to explore this innovative educational strategy.
An analytical mechanics approach to the first law of thermodynamics and construction of a variational hierarchy
Authors: Said Hamid
Published: November 2020

A simple procedure is presented for the study of the conservation of energy equation with dissipation in continuum mechanics in 1D. This procedure is used to transform this nonlinear evolution-diffusion equation into a hyperbolic PDE; specifically, a second-order quasi-linear wave equation. An immediate implication of this procedure is the formation of a least action principle for the balance of energy with dissipation. The corresponding action functional enables us to establish a complete analytic mechanics for thermomechanical systems: a Lagrangian?Hamiltonian theory, integrals of motion, bracket formalism, and Noether?s theorem. Furthermore, we apply our procedure iteratively and produce an infinite sequence of interlocked variational principles, a variational hierarchy, where at each level or iteration the full implication of the least action principle can be shown again.

Published: November 2020

Praktik jual beli padi dengan sistem tebas terjadi di Desa Mlaten. Adapun praktik jual beli ini adalah petani melakukan transaksi dengan penebas pada saat tanaman padi sudah tampak dan menguning tetapi belum layak panen dengan pemberian uang muka sebagai tanda jadi. Setelah transaksi, penebas tidak langsung memanen biji tersebut, melainkan menunggu hingga padi sudah layak panen. Dan pada saat itulah penebas baru mengambil tanaman padi yang sudah dibelinya sekaligus melunasi pembayaran. Penelitian ini bertujuan untuk mengetahui bagaimana tinjauan hukum Islam terhadap pratik jual beli padi dengan sistem tebas di Desa Mlaten Kabupaten Demak.. Jenis penelitian ini adalah penelitian lapangan (field research) dengan menggunakan pendekatan deskriptif, yaitu penelitian yang bertujuan untuk menyesuaikan antara dalil dengan praktik jual beli secara tebas di Desa Mlaten sehingga menghasilkan hukum yang dimaksud. Dalam pengumpulan data penelitian ini menggunakan metode wawancara, dokumentasi dan observasi. Penelitian ini menghasilkan temuan yaitu transaksi jual beli padi dengan sistem tebas di Desa Mlaten tersebut adalah sah menurut analisis hukum Islam, karena sesuai dengan rukun dan syarat jual beli, yaitu: Āqidain, Ma’qūd ‘alaih dan Sighat (ijāb qabūl) serta terhindar dari beberapa kemungkinan fasad, seperti gharar, Riba, satu transaksi dalam dua maksud serta pemanfaatan dan perawatan tanah oleh pembeli.
MENATAP MASA DEPAN PERADABAN ISLAM
Authors: Waston Waston
Published: November 2020

Secara historis, Islam sebagai sebuah peradaban dimulai dari sintesis kreatif. Sintesis kreatif bisa terjadi  jika seseorang memiliki beberapa bidang ilmu sekaligus. Di era klasik, antara abad IX dan XIV, peradaban Islam menunjukkan kreativitas tinggi dalam ilmu dan teknologi. Pemikiran kreatif di zaman keemasan Islam tercermin dalam diri Al-Farabi, Ibnu Rusyd, Ibnu Sina dan lain-lain merupakan hasil sintesis secara intensif dengan falsafah Yunani. Oleh karena itu,   peradaban Islam di masa depan harus   bersintesis   dengan teknologi, ekonomi  dan   globalisasi. Perlu penggeseran wilayah pemikiran yang dulunya hanya memikirkan persoalan-persoalan “teologi” (Ketuhanan) klasik ke arah paradigma pemikiran yang lebih menelaah dan mengkaji secara serius persoalan-persoalan “kemanusiaan” (antropologi) yang bersifat global. Melahirkan peradaban Islam di Indonesia di era globalisasi ini tentu bukan pekerjaan mudah karena itu dibutuhkan agenda, koordinasi terpadu dan komprehensif oleh semua agen perubahan sosial.
Entrepreneurship Education in Nigeria Tertiary Institutions and its Impact on Students’ Entrepreneurial Career Intentions. A Study of Students at Federal Polytechnic Ekowe
Authors: Fems Kurotimi Maurice
Published: November 2020

Purpose: Entrepreneurship education as an influencer of graduate entrepreneurial intention is gaining massive attention amongst practitioners, policy makers and academics across the globe. The proliferation of entrepreneurship courses in universities around the world is evident of this wide acceptance of entrepreneurship education as a strategy for graduate entrepreneurship. The purpose of this research paper is to ascertain the impact entrepreneurship education has on students’ entrepreneurial career intentions.Methodology: The article includes a review of literature in entrepreneurship education and entrepreneurial intention to gain background knowledge. This research is a qualitative, interpretive phenomenological study and relies on narrative as a means of knowing, and as a form of communication. The scope of the study is year one students at the Federal Polytechnic of Oil & Gas Ekowe in the departments of Computer Science, Science Laboratory Technology and Statistics. The questionnaire was designed in a semi-structured way and distributed to students to return after 7 days to allow for proper articulation of narratives.Findings: A total of 42 students participated in the interview and 42 returned. 28.57% representing 12 students showed intention to start a business, 40.48% (17 students) desire to get a job after graduation while 13 students (30.95%) are unsure what they want to do after graduation. The results indicate that entrepreneurship education has a positive impact on students’ entrepreneurial career intention but other than EE, it was also revealed from participants’ narratives that age, prior experience and parents’ status have positive influence on graduate entrepreneurial decisions.Implication of Findings: Findings will aid curriculum designers and educational policy makers to scrutinize and re-examine EE programmes and how they are taught to enhance practice.Originality: Narratives and storytelling methods are not the common methods adopted in entrepreneurship education and entrepreneurial intention research. More research should be carried out using this method to validate results from this approach.
