Training on HINTS exam: Results from a quasi - experimental study in Medicine Students
Authors: Castillo-Bustamante Melissa , García Alejandro , Madrigal Jorge 
Published: May 2023

Abstract
HINTS (head impulse, nystagmus, and test of skew) protocol is widely used at emergency rooms and outpatients’ settings to differentiate central from peripheral vertigo. Doctors usually get experience during their training on the basic concepts of the test. However, there is a lack of information about the current understanding of the test and its application by future practitioners, who will be the first responders to vertigo patients. We conducted a quasi-experimental study to assess the understanding, applicability, and comprehension of HINTS in medical students after a theory and practice session and follow-up 1-month after. Twenty-one students were evaluated with pre-test and post-tests. Comprehension (Δ40%), understanding (Δ60%) and applicability (Δ48%) were increased after the session. Head impulse (Δ 39%), nystagmus evaluation (Δ 10%) and test of skew (Δ 39%) showed a better understanding and comprehension even 1-month after. Findings have educational implications of this protocol in future healthcare professionals.

Published: May 2023

Abstract
Objective:
DVT prophylaxis is often delayed in head -injured patients because clinicians believe that the risk of bleeding from prophylaxis is more critical than the risk of venous thromboembolism.
Material & Methods:
All head injury admissions between September 2021 and September 2022 were selected for inclusion in this study. Patient data including age, sex, injuries, Glasgow Coma Scale, Injury Severity Score, were collected. Chemical prophylaxis, either heparin or enoxaparin, was started as soon as it was considered safe. Patients with traumatic intracranial hemorrhage were followed up with brain computed tomography to examine the safety of chemical DVT prophylaxis.
Results:
A cohort of 100 patients was studied during the one year study period. Their average GCS scores and Injury Severity Score scores were 11 and 14 respectively. Overall, 68% of patients suffered from mild to moderate head injuries. Fifty-nine percent of patients were poly-traumatized with different types of extracranial injuries. 60% were managed conservatively and 40% needed surgical intervention. Overall, 75% of patients received chemical DVT prophylaxis and 25% received mechanical prophylaxis. 50% received early chemoprophylaxis, that is within 72 hours, 25% received late prophylaxis, that is after 72 hours. The average delay in start of DVT prophylaxis was 2.9 days. 2.4% of patients developed DVT in spite of prophylaxis but no one developed any expansion of intracranial hemorrhage .
Conclusion:
This study concluded that early DVT prophylaxis in head-injured patients is safe and effective.
Cyclic loading tests on proppant in hydraulic fracture by discrete element method
Authors: Fang Tian , Liu Weiqun , Yang Rui , Qi Dachao , Liu Xuyang 
Published: May 2023

Abstract
In this paper, discrete element method (DEM) is used to generate randomly stacked proppant layer, and the particle size distribution, Young's modulus and initial stacking of proppant are considered. Based on these discrete stacking structures, cyclic uniaxial compression tests (ucts) were carried out, and mechanical and seepage analysis of the proppant layer was carried out. Larger particle size and larger Young's modulus will make the equivalent elastic modulus of particle combination larger. The particle distribution has a certain effect on the permeability coefficient of the whole combination in given condition.
Updated transient gene expression protocol and the development of a small-scale transient gene expression protocol -evaluated by testing of longevity molecules as potential protein expression enhancers

Abstract
Transient gene expression (TGE) is commonly used to quickly produce protein-based drugs, such as antibodies, that require post-translational modifications. We have previously published a protocol for efficient and inexpensive TGE of multispecific and multivalent antibodies, which we have improved upon and described in the first part of this paper; by replacing the expensive Expi293 expression with BalanCD HEK293 medium, the medium cost was decreased by approximately 90%, and in addition, the harvesting procedure was shortened from 2.5 hours to 15 minutes by mixing the harvested cell media with the mineral compund diatomaceous earth that effectively absorbs and sequester cells and cell debris. The cell media can then be quickly filtered without the need to exchange obstructed filters and without the previously required 1-hour centrifugation step. In the second part of this paper, a small-scale TGE protocol was developed to surmount the cost limitation of testing many culture conditions. The small-scale TGE protocol uses 6-well plates which is the cheapest alternative for scaling down the protein expression, and consumes 83% less material compared to transfections done with the smallest available shaking flasks for cell culture. To test the small-scale TGE protocol we evaluated substances, belonging to a category called longevity molecules, as potential protein expression enhancers. Though the longevity molecules failed to increase protein expression in the conditions tested, our results corroborates the functionality of the small-scale TGE protocol and provides a simple methodology to expediently evaluate factors that can lead to improved protein production protocols in the future.

Abstract
This work presents an integrated plant-wide process for co-gasification of waste biomass and plastics using steam and CO2 to produce an industrially important feed stock i.e., syngas with molar ratio of H2/CO ~ 2. The proposed plant wide process is designed with key feature of carbon capture and utilization (CCU) and made self-sustainable by utilizing a fraction of syngas for meeting the heat, steam and CO2 demands with additional heat recovery and steam generation and power generation sections. Further, steady state plant wide models are developed using ASPEN Plus, and simulations are performed for the co-gasification of high-density polyethylene (HDPE) and rice husk (RH) at varying feed compositions (0-100% HDPE). Further, rigorous sequential parametric sensitivity analysis is performed to determine the optimal process parameters and investigate the impact of feed composition on the product yield. Results revealed that steam to carbon ratio (S/C) should be maintained above 1.2 to attain complete carbon conversion within the gasifier which tends to enhance the overall performance of the integrated scheme. The comparative investigation on co-gasification of HDPE and RH revealed that an increase in weight percentage of HDPE in the feed mixture resulted in increased syngas production and plant efficiency due to the high carbon and low ash content of HDPE. Gasification of pure HDPE waste resulted in the maximum output of 2.2 kg of syngas/kg of feed with a net plant efficiency of 68%, while in the case of pure RH the syngas production and efficiency dropped to 0.60 kg/kg of feed and 35%, respectively.

Based on the enactment of official government regulations in Governor Regulation No. 1 of 2020 concerning the Governance of Balinese Fermented and Distilled Drinks, arak Bali has started to appear publicly. It brings many advantages for the Balinese, especially in the business of fermented drink production. However, it is still unknown about consumer behavior regarding the interest in arak Bali, especially among Balinese people who live socially. The research aimed to determine the effect of social influence, product knowledge, and Fear of Missing Out (FOMO) on purchase intention in arak Bali. The population used was millennials and Generation Z in Denpasar City who had looked for information and consumed arak Bali. The amount of sample used was 153 respondents. Then, data analysis model used the Structural Equation Model (SEM) with AMOS 24. Based on the results of data processing with AMOS 24, it can be concluded that there is a significant and positive effect of social influence on purchase intention, product knowledge on purchase intention, social influence on FOMO, and product knowledge on FOMO. Meanwhile, FOMO has no significant but positive effect on purchase intention. It is known that the effect of product knowledge on purchase intention has the greatest influence and value in the research.

Abstract

The scarcity of freshwater is one of the biggest issues in the world, as a result of which more attention is given to the thermal distillation process for seawater and as well as brackish water distillation which removes almost all types of contaminants. Multiple effect distillation makes the process economical by recycling the latent heat of vaporization. In this paper a vertical tube evaporator is designed for a small scale thermal driven MED system comprising six effects and one condenser and a boiler that can produce 20–25 kg/hr of steam. VTE dimensions are calculated by estimating the outside diameter for different configurations. Heat transfer coefficient was estimated by using the developed correlations of the Bell method, Kandlikar and Kutateladze, compared with previous experiments and then used for calculating the heat transfer area for different distillate flow rates. An appropriate vertical tube evaporator is designed with the developed model to condense 25–30 kg/hr steam for producing 50–75 lt/hr freshwater. The result shows good agreement with previous work and reliability in design. The Developed model can also be used to design the vertical tube evaporator for different sizes (micro scale to large scale) MED plant.

TINJAUAN HUKUM EKONOMI SYARIAH TERHADAP SISTEM BAGI HASIL NGAWALI KORO
Authors: Eriyanti Nahara 
Published: May 2023

Pada dasarnya dalam teori bagi hasil yang ada dalam Islam disebut akad Mudharabah yaitu kerja sama antara dua pihak untuk menjalankan suatu usaha tertentu, di mana pihak pertama sebagai pemilik modal kemudian pihak kedua sebagai pengelola. Hal ini berlaku pula pada kegiatan kerjasama di bidang peternakan kerbau atau biasa disebut Ngawali Koro di Desa Tungel Kecamatan Rikit Gaib Kabupaten Gayo Lues, Namun pada praktiknya Pembagian keuntungan dari hasil Ngawali koro hanya dilakukan jika kerbau sudah beranak minimal tiga ekor, di situlah si pemilik modal akan membagi satu ekor kerbau kepada si pengelola sebagai hitungan bagi hasil. Penelitian ini bertujuan Untuk mengetahui Bagaimana pelaksanaan perjanjian kerja sama bagi hasil Ngawali Koro , serta tinjauan hukum ekonomi syariah terhadap sistem bagi hasil pada masyarakat di Desa Tungel, kecamatan Rikit Gaib, Kabupaten Gayo Lues. Jenis penelitian ini adalah penelitian Lapangan (field research) yang dilaksanakan di Desa Tungel, Untuk mendapatkan data yang valid, peneliti menggunakan beberapa metode pengumpul data yaitu wawancara, dokumentasi dan observasi setelah data tersebut terkumpul maka dianalisis menggunakan metode deskriptif kualitatif. Hasil penelitian ini menunjukkan bahwa pelaksanaan bagi hasil hewan ternak di Desa Tungel Kecamatan Rikit Gaib Kabupaten Gayo Lues menggunakan sistem Nisbah bagi hasil keuntungan yang akan diberikan dalam bentuk anak kerbau bukan upah. Ketika hewan ternak itu sudah beranak minimal tiga ekor, maka si pemilik modal akan membagi satu ekor kerbau kepada si pengelola sebagai hitungan bagi hasil. Praktik pembagian keuntungan pada kerjasama Ngawali Koro tidak sesuai dengan konsep mudharabah dalam Islam, karena pembagian keuntungan terdapat unsur ketidakjelasan kepada pengelola kerbau tersebut.

Published: May 2023

Sekalipun sewa menyewa rumah dengan sistem panjar sudah menjadi praktik umum dalam masyarakat khususnya di Kecamatan Syiah Kuala Kota Banda Aceh, namun jika dirujuk dari Literatur Fiqh Islam, sesungguhnya masih terdapat perbedaan pendapat ulama tentang kebolehannya. Sebagian ulama berpendapat jual beli dengan menggunakan uang panjar tidak sah, sedangkan dari kalangan ulama lainnya menyatakan bahwa jual beli dengan meggunakan uang panjar sah dan boleh dilakukan. Oleh karena itu, penelitian ini bertujuan mengetahui bagaimanakah sistem panjar dalam sewa menyewa rumah di Kecamatan Syiah Kuala Kota Banda Aceh dan bagaimanakah tinjauan konsep ijārah bil manfa’ah terhadap sistem panjar dalam sewa menyewa rumah di Kecamatan Syiah Kuala Kota Banda Aceh. Metode yang digunakan adalah deskriptif kualitatif, sumber pengumpulan data yang diperoleh dari penelitian lapangan (field research) dan studi kepustakaan (library research). Berdasarkan hasil penelitian, praktik sewa menyewa rumah di Kecamatan Syiah Kuala Kota Banda Aceh, penyewa harus membayar uang panjar minimal 20 % dari harga total. Apabila calon penyewa membatalkan sewa rumah maka uang panjar tersebut tidak dikembalikan atau hangus. Tinjauan fiqh muamalah terhadap praktik urbun pada penyewaan rumah belum sepenuhnya sesuai, berdasarkan jumhur ulama bahwasanya, urbun mengandung unsur gharar dikarenakan ketidakjelasan terhadap batas maksimal pembayaran, sehingga penyewa dan pihak pemilik rumah sewa sama-sama mengalami kerugian.

The purpose of this study is to discuss the practice of determining the selling and buying price of rice that is practiced by the people in Aceh Besar district. In this practice, there are two times for determinations the sale and purchase price of rice which is considered to contain an element of gharar in the second price determination. This research will explain: how the mechanism of the practice, a review of Islamic law related to the practice, whether the practice can be practiced in other areas. This study uses field research methods with data collection techniques in the form of interviews. The results of the study concluded: (1) In the practice of two times price determination buying and selling rice, there are three types of contracts used, that is the ba'i, hybrid contract between ba'i and wadiah and a hybrid contract between ba'i and qardh. (2) The practice using a ba'i is legal by refers to the rules of ushul fiqh related to the basic law of muamalah that is mubah. The legality is also supported by urf which is able to bring benefit even though it contains elements of gharar in it. The element of gharar in the second price fixing is considered gharar yasir which is legal because it has become 'urf that is able to present benefits and mutual pleasure towards the consequences that arise from the gharar element. Two other types of contracts, a hybrid contract between ba’i with wadiah and a hybrid contract between ba’i with qardh according to the Islamic law riview, they are not contrary to Islamic Law. (3) Although in real terms this practice can increase farmers' income, this practice cannot be practiced in other areas.

Women are often positioned as marginal people in various fields of life, including the position of Balinese women in managing tourism in Bali. This article aims to analyze the position of Balinese women in tourism management in Bali. This research is a literature study with a qualitative descriptive analysis. This research found that Balinese women are very enthusiastic as homeworkers because they are related to domestic activities. These symptoms are related to the ideological superstructure and work ethic. This study also found that social structure and material infrastructure strengthen the work ethic. Balinese women think that work is yadnya, needs to be carried out and practiced to improve self-quality. Even though Balinese women experience injustice in the management of tourism in Bali, they are still eager to earn a living.
