Financial transactions in Islamic banking are viable alternatives to the conventional banking transactions

Islam has prohibited riba (interest) on loan given. When a lender lends money to another person, he is allowed to get back the capital amount only and not any additional amount which is usually fixed interest on the capital. Taking interest on loan given caused cruelty and injustice to poor people in the society during prophet Muhammad’s time who were unable to pay back the capital and the interest. So, Prophet Muhammad encouraged the rich people to give qard al-hasan (interest free loan) to the poor and needy people to help them to solve their problems. That’s why Allah (the Creator) prohibited taking interest but encouraged people who have money to invest the money in business. The profit obtained from business is permitted (halal) but fixed rate interest taken on loan given to a person is riba (interest) and it is prohibited. As Allah (the Creator) has prohibited interest, Muslims are prohibited to give interest, to take interest and to write down the interest transaction. Hence, Muslim scholars have invented some Islamic transactions which do not involve interest and Islamic banks are adopting these Islamic transactions. The objective of this paper is to narrate and analyze the Islamic banking transactions which are interest free and they are considered as alternatives to the conventional banking transactions

Modification of Drafting Zone of Jute Flyer Spinning Frame to Improve the Jute Yarn Quality

Being concerned with the growth and sustainability of the jute industry of Bangladesh, the machinery modifications deserves higher priority. In this work, it is desired to perform a modification of the apron draft spinning frame to improve the jute yarn quality. However, the existing drawing pressing roller (Diameter=70 mm & Durometer hardness = 96 in Shore A Scale) of the drafting zone of the apron draft jute spinning frame has been replaced by a comparatively softer rubber coated top roller (diameter= 40 mm & Durometer hardness = 85 in Shore A Scale). Besides, an extra slotted roller (Diamter= 26 mm & Durometer hardness = 74 in Shore A Scale) has also been nipped with bottom drawing roller and positioned parallel to the modified top roller. Three types of modifications have been designed by varying slot angles (i.e., 45°, 60°, and 75°) of slotted roller attached with the modified top roller. Finally, jute yarn counts of 6.5, 8, and 10 lbs/spyndle have been produced for both existing and modified frames. Results reveal that the modified spinning frame with all three types of slotted roller produced better results regarding the yarn hairiness compared to the existing frame irrespective of yarn fineness. Yarn hairiness values in modified frame with 60° slotted roller have been decreased maximum by 28.1%, 35.85%, and 32.92% compared to that of the existing system for 6.5, 8, and 10 lbs/spyndle respectively. Yarn strength results have been improved with the modified system as well. Lastly, it is seen that ends down rate in modified spinning frames have been reduced noticeably irrespective of yarn fineness

Kajian Karakteristik Dasar Aspal Modifikasi dengan Penambahan Plastik Polyethylene Terephthalate (Pete/Pet)

Perkerasan jalan di Indonesia pada saat ini sebagian besar menggunakan aspal minyak (aspal konvensional) dengan penetrasi 60/70. Akan tetapi penggunaan aspal konvensional masih memiliki kelemahan, salah satunya adalah perkerasan jalan tidak mampu menahan beban lalu lintas yang berlebihan dan temperatur tinggi sehingga menimbulkan deformasi. Salah satu cara untuk meningkatkan mutu campuran beraspal adalah dengan menambahkan plastik yang dalam istilah kimianya disebut polimer. Pemberian bahan tambahan polimer diharapkan memberikan penambahan pada sifat-sifat fisik aspal seperti kepekaan terhadap temperatur dengan meningkatkan nilai titik lembek, dan kinerja terhadap stabilitas yang lebih besar dari aspal konvensional atau aspal penetrasi 60/70. Salah satu material yang bisa dimanfaatkan dalam kaitan ini adalah limbah plastik Polyethylene Terephthalate (PETE/PET). Limbah plastik PETE/PET dipilih sebagai polimer karena sifat plastik PETE/PET yang tahan terhadap panas dan juga mampu untuk menaikkan titik lembek aspal. Penelitian ini bertujuan untuk mengetahui karakteristik dasar aspal modifikasi plastik PETE/PET (Penetrasi, titik lembek, titik nyala dan titik bakar, berat jenis, daktilitas, dan viskositas) serta mengetahui persentase kadar plastik PETE/PET untuk menghasilkan aspal modifikasi yang memenuhi standar Bina Marga. Dalam pelaksanaannya, penelitian ini dilakukan dengan metode eksperimen laboratorium. Variasi penambahan plastik Polyethylene Terephthalate (PETE/PET) yang digunakan adalah 0%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 20%, 30%, 40%, dan 50%. Pengujian aspal modifikasi dengan penambahan plastik Polyethylene Terephthalate (PETE/PET) menunjukkan hasil yang signifikan terhadap penetrasi, titik lembek, dan nilai daktilitas. Secara keseluruhan, kualitas aspal yang dimodifikasi dengan plastik Polyethylene Terephthalate (PETE/PET) menghasilkan sifat yang lebih baik dibandingkan dengan aspal murni

Prediction of preterm premature membrane rupture by the platelet-lymphocyte ratio

Background: Premature rupture of membranes is a significant obstetric problem. Evaluating platelet -lymphocyte ratio is expected to illuminate the potential scope of early prediction of PPROM. This study showed that PLR could be a new inflammatory marker for diagnosing preterm PROM. Methods: The study place was the Department of Obstetrics and Gynaecology, Sir Salimullah Medical College & Mitford Hospital, Dhaka, Bangladesh, from May 2019 to October 2019.  Results: It was a case-control study. All mothers were selected by purposive sampling who were PPROM as cases. Age-matched non-PPROM pregnant women at term were also enrolled as control. Afterward, they were scrutinized according to eligibility criteria, and 200 mothers were enrolled. Among them, 100 were cases, and the other 100 were in control. A pre-tested, observation-based, peer-reviewed data collection sheet was prepared before the study. Data regarding clinical, biochemical, and surgical profiles were recorded. Data were compiled, edited, and analyzed. The P-value was determined by the chi-square test (categorical variables) and the student’s t-test (continuous variables). The p-value was significant at <0.05. Conclusions: The mean age of 100 patients from the case was 24.39±2.81 (age range: 18-36) years, and that of the control, like 100 normal pregnant women, was 24.31±2.34 (age range: 19-35) (p=0.49). The mean parity of case and control were 2.1±0.9 (range: 0-5) and 1.98±0.2 (range: 0-3). The mean gravida of case and control were (3.1±1.2 vs. 3.4±1.4). Platelet count was found to be significantly higher in preterm PROM group (case) than control (241.6±58.7×1000/mm³ vs. 201.7±65.9 ×1000/mm³), p value is <0.001 which is statistically significant. So, PLR might be an excellent inflammatory biomarker to predict preterm PROM

Solution Blow Spinning (SBS): A Promising Spinning System for Submicron/Nanofibre Production

Submicron/nanofibres possess great potential for application in different areas because of their amazingly high surface area-to-weight ratio. The demand for fabrication of such fibres on a huge scale is increasing with the fast improvement of nanotechnology. Traditionally, nanofibre fabrication methods have intrinsic faults, limiting their application in industry. Solution blow spinning (SBS) is a viable option for producing adaptable and conformable submicron/nanofibre mats on a variety of surfaces. The technique can be employed to produce submicron/ nanofibres with only a simple commercial airbrush, a concentrated polymer solution, and a compressed gas source. It depends on the high velocity of decompressed air that allows the rapid stretching and evaporation of the solvent from a polymeric solution jet at the outlet of the concentric nozzles system. Along with recent advancements, the importance and drawbacks of the solution blow spinning system in comparison to other methods, such as electrospinning and melt blowing, are briefly discussed. Furthermore, the mechanisms of co-axial SBS spinning and micro SBS spinning system for submicron/nanofibre fabrication are also described. Drawbacks and research challenges of SBS are also addressed in this paper

Pro-Environmental Behaviours among Frontliner Employees in Oil and Gas Industry: Does Environmental Work Culture Really Matters?

Abstract. This study investigates the employee perceptions of organizational environmental initiatives and their impact on pro-pro-environmental behaviors and frequency of involvement in upstream oil and gas companies in Malaysia, such as the Production Arrangement Contractor and Service Provider Company. The study also examines a new area where environmental work culture acts as a moderator. Analyzed using SmartPLS, our findings demonstrate that supervisory support for environmental initiatives and environmental training has a positive effect on employee perception of organizational support for pro-pro-environmental behaviors. In contrast, the organization's rewards for pro-environmental behaviors do not have a significant impact on it. Following this, the employees' perceptions of organizational support for pro-environmental behaviors positively affect employee engagement in pro-environmental behaviors in both forms of employees' frequency of involvement and employees' innovative pro-environmental behaviors. The findings discovered that environmental work culture moderates the relationship of the effect of the organization's support practices on employee perception of organizational support for pro-environmental behaviors. This study is one of the first attempts to investigate the relationship between the pro-environmental behaviors within the upstream firms in the oil and gas industry. The findings are useful for practitioners in terms of exerting pro-environmental behaviors and facilitating employees' pro-environmental behaviors in the upstream oil and gas management sector.      Keywords:  Employee perceptions, pro-environmental behaviors, organizational support, work cultur
