Published: March 2022

Effects of salt stress on seedling growth and ion accumulation in 6 accessions of two Sesbania species viz. S. bispinosa (Jacq.) W. Wight (4 accessions: #1, #5, #7 and #59) and S. cannabina (Retz.) Poir. (2 accessions: #82 and #85), was evaluated in a hydroponic experiment under 0 (control) and 10 dS/m salinity stress. Salt stress significantly affected negatively seedling growth and different ion contents in 6 accessions of Sesbania seedling except for Na+. The relative values, per cent reduction over control, of all morphological and physiological descriptors, were significantly higher indicating superior salt tolerance in accession #59 compared to other accessions studied. The Na+ accumulation was higher in root compared to shoot; however, a reverse scenario was observed for K+ and Ca2+. No distinct difference in salt tolerance was observed between S. bispinosa and S. cannabina. Accession #59 could, therefore, be suggested for cultivation at salineprone areas of Bangladesh. However, it needs further confirmation at the farmer’s saline field condition.

Authors: Akter Nazma
Published: March 2022

Background: Diabetic populations and people from developing countries have a higher risk of developing CVD than the general population. Bangladesh, a rapidly developing country, faces progressive urbanization and the adoption of a westernized lifestyle, factors which contribute to the rising burden of cardiovascular disease.

Objective: To predict the risk of developing cardiovascular diseases among diabetic patients in Bangladesh.

Materials and method: This cross sectional study was done among the diabetic patients attending the outpatient department of MARKS Medical College &Hospital, Dhaka, Bangladesh from February 2018 to July 2018. Patients suffering from any cardiovascular disease were excluded from the study. The purpose of the study was explained and informed written consent was obtained from each subject who volunteered for the study. Data was collected with a pre tested structured questionnaire. Cardiovascular risk was assessed based on Framingham scoring, calculated by using online calculator and expressed as percentages. Based on the total risk score calculated, subjects were categorized to be at high (≥20%), intermediate (10-19%), and low (<10%) risk of cardiovascular disease. Data analysis was done in SPSS software version 16.

Result: Among the diabetic patients, 32.62% are in high and 22.64% are in intermediate risk category based on Framingham scoring system for developing cardiovascular disease. A statistically significant association was found between cardiovascular risk and factors like gender, occupational status, smoking and hypertension.

Conclusion: This study reveals that the diabetic populations are at higher risk of developing cardiovascular diseases. Hence awareness about the risk should be created and appropriate intervention at early stages should be implemented at primary health care level.

A robust and efficient automated product recognition system based on scenario design methodology and computer vision techniques
Authors: Fung Wai Tong , Lam Kin Man
Published: March 2022

Automated product recognition systems should minimise the online product verification time while keeping product recognition robust to human interventions, including misplaced products, rotated products and empty shelves. A predefined template of each product is generated offline, and scale and location invariant binary local features are employed for recognition. Three types of Sampling Bounding Mask (SBM) are defined and combined with RGB/LUV colour histograms, and matched with a planar level of a shelf by using the Earth Mover’s Distance, thereby reducing the computation time by 50%. Eight comprehensive product views are used to define five product scenarios on a shelf. The SBMs can be used to accurately distinguish the scenarios in a region at a level of shelf. By identifying four scenarios where a shopkeeper does not need to take any action to immediately reallocate misplaced products on shelves, the computation time is reduced by 80%. Six invariant keypoints and feature computation methods are compared for the recognition of product shelf items in different scenarios. The proposed approach speeds up the process by 200% to 300% for product matching. By integrating SBM view detection, the accuracy of product recognition in the front-view with rotations ranges from 90% to 95% using six different feature descriptors.
Benchmarking site-plant resource matching performance of ready-mixed concrete delivery and placing
Authors: Siu Francis Ming Fung , Wong Anson Kwun Wang , Anson Michael
Published: March 2022

Since on-time concrete delivery is important to both contractors and suppliers, performance benchmarking of the concrete delivery process, as actually achieved in practice, is a worthwhile undertaking of potential benefit to the construction industry. However, there has been no thorough such benchmarking in Hong Kong for 20 years, since the study by Anson et al. (2002). This research study has provided an up-to-date benchmark of the site/supplier resource matching, or coordination, performance for big building superstructure pours, based on study of the records of 77 pours placed on five buildings under construction in Hong Kong. This research study also aimed to assess whether there was any evidence to suggest that site/ plant coordination performance has improved since 2000, not least due to the adoption of advanced technologies, which nowadays monitor the locations of truckmixers in real time throughout the day. Of great importance to the industry, however, and the most significant finding arising from this study, is that there is no support for the proposition that site/supplier resource coordination has improved over that 20-year interval. Truckmixer position tracking systems need to be capitalised upon with the introduction of data analysis simulation software and optimising scheduling applied in real time.
Effect of cardiac lymph flow obstruction on cardiac collagen synthesis and interstitial fibrosis
Authors: Kong D , Kong X , Wang L
Published: March 2022

The effect of chronic cardiac lymphatic obstruction on the myocardial synthesis of collagen type I and III was investigated in a rabbit model. In the lymphatic obstruction group (n=16), plasma C-terminal propeptide type I procollagen (PICP) and N-terminal propeptide type III procollagen (PIIINP) were elevated at 7, 14 and 30 days after the operation (p<0.05). The elevated PICP and PIIINP returned to the pre-operation values 60 days after the operation. The myocardial expression of collagen type I and III mRNA were also enhanced in the lymphatic flow obstruction group. Plasma PICP, PIIINP and myocardial collagen type I and III mRNA remained unchanged in the control group (n=16). We concluded that chronic obstruction of cardiac lymph flow leads to enhanced myocardial collagen synthesis in rabbits. The enhanced collagen synthesis starts within seven days after lymphatic obstruction and subsides after 60 days.

Published: March 2022

BACKGROUND: High +Gz exposure is known to cause spinal problems in fighter pilots, but the amount of tolerable cumulative +Gz exposure or its intensity is not known. The aims of this study were to assess possible breaking points during a flight career and
to evaluate possible determinants affecting pilots’ spines.METHODS: Survival analysis was performed on the population who started their jet training in 1995–2015. The endpoint was permanent flight duty restriction due to spinal disorder. Then the quantified Gz
exposure and possible confounding factors were compared between those pilots with permanent flying restriction and their matched controls. Cumulative Gz exposure was measured sortie by sortie with fatigue index (FI) recordings. FI is determined by the number of times certain levels
of Gz are exceeded during the sorties.RESULTS: The linear trend of the survival curve indicates an annual 0.86% drop out rate due to spinal problems among the fighter pilot population. A conditional logistic regression did not find any difference in the FI between cases
and controls (OR 0.96, 95%CI 0.87–1.06). No statistical difference was found for flight hours, a sum of intensive flying periods, fitness tests, or with nicotine product use. Additionally, a maximum +Gz limitation without airframe restriction was assessed and is presented
as a useful tool to manage loading and developed symptoms.DISCUSSION: No particular breaking point during follow-up or individual factor was found for Gz induced spinal disorders. The results of the study outline the multifactorial nature of the problem. Thus, multifactorial
countermeasures are also needed to protect pilots’ health.Sovelius R, Honkanen T, Janhunen M, Mäntylä M, Huhtala H, Leino T. +Gz exposure and flight duty limitations. Aerosp Med Hum Perform. 2022; 93(4):390–395.

The goal of Society 5.0 is to create a human-centric society that solves economic development challenges so that people can enjoy an active, comfortable, and high-quality life. Society 5.0 is a society that thoroughly provides various needs of people, regardless of region, age, sex, language, etc., by supplying all the items and services required for the continuation of the society itself. This paper focuses on our attempt to facilitate transportation technology as one of the drivers to achieve Society 5.0 Sustainable Development Goals (SDGs) through Costless Smart Transportation (CST). Our approach delivered a costless transportation service for the society while still being able to provide profits to the management and business partners. Our implementation strategy of the technology is focused on tourism, education, retail, culinary, and industrial that also provides business opportunities to other sectors. The implementation of the business model is realized through a web-based administrative system and a mobile app for clients and business partners. Our pilot study has shown that the proposed business model allows all levels of society to participate and benefit from it yet allows the program to be sustainable in the long run.
Asymmetric Effects of Trade Openness on Malaysian Fish Trade Balance
Authors: Bee-Hui Soh  , Ghee-Thean Lim  , Soo-Yean Chua
Published: March 2022

Although Malaysia is a small open economy surrounded by the ocean, it still experiences a critical fish trade deficit. This study examines the nonlinear effects of trade openness on Malaysian fish trade balance from 1976 to 2016, using the Nonlinear Autoregressive Distributed Lag (NARDL) approach. The other independent variables applied in the model are the exchange rate and domestic income. Findings show that the variables are cointegrated. In the long-run, positive change in trade openness has a significant negative effect on the trade balance. The emphasis of the study is also placed on shreds of evidence of the long-run and short-run asymmetric effects of trade openness. Domestic income and depreciation of the exchange rate offer significant positive impacts on the trade balance. In the short-run, all the variables yield an opposite effect. The outcome of the exchange rate supports the J-curve effect and the Marshall-Lerner condition. This research may help the policymakers and traders to have a better understanding of the sector and thus develop suitable long-term strategies to improve the fish trade balance.

Published: March 2022

The objective of this study is to examine the trends related to the Shariah compliance practice among Islamic banks in Nigeria. It is also conducted to establish the loopholes in the existing Islamic banking system and to suggest measures to remove Shariah non-compliance in Islamic banks in Nigeria. The study is based on primary data. The data was gathered through a questionnaire survey with the employees, researchers, and Islamic banking experts. The study is based on descriptive findings by analysis of mean, standard deviation, and variance to examine the trends of Shariah compliance practice in Islamic banks in Nigeria. The study found that Islamic banks in Nigeria are doing well in terms of Shariah compliance practice relating to their products and services. Besides, the advisory committee of experts are quite knowledgeable in determining fatwa and rulings in all Islamic banking matters in Nigeria. This is because Shariah compliance is considered as the backbone of Islamic banking as it gives legitimacy to their products and services. The study has implications for all the banks, customers, Shariah Advisory Committee, regulatory bodies, and other stakeholders in Nigeria to further checkmate the various factors that could prevent Shariah non-compliance. The study, therefore, recommends extensive efforts via Shariah knowledge and seriousness of the bank employees as well as regulatory authorities to enforce Shariah compliance thereby guiding customers to choose Islamic banking products in a better and improved way.

Published: March 2022

The coronavirus disease (COVID-19) has transformed conventional buying to online shopping habits. Despite the importance of customers’ future behaviour, insufficient studies have highlighted the role of online shopping habits on the intention to recommend. The study investigated how the Big Five Personality Traits (BFPT) influence online shopping habits, the relationship between habit and intention to recommend, and the habit as a mediator by applying the convenience sampling method. A total of 347 usable data were collected online and analysed using structural equation modelling with the Smart Partial Least Squares (Smart PLS) software. The study found that agreeableness, conscientiousness, extraversion, and neuroticism positively affect online shopping habits, but not openness. Furthermore, online shopping habits positively impact the intention to recommend and mediate the relationship between the BFPT and the intention to recommend. The study also provides valuable information for conventional stores and online platform managers to develop marketing strategies to retain and attract new customers. Moreover, the study discussed the limitations and future research recommendations.

Published: March 2022

In today’s challenging global economy, risk management is encountering a significant transformation. Organizations are switching their risk management method to enterprise-wide from the traditional compartmentalized approach. Enterprise risk management (ERM), which aims at increasing the sustainability of an organization and achieving competitive advantage, is gaining global attention and fast becoming an essential concern in all industries. Despite the importance of the knowledge embedded in people in the current knowledge-based economy, there remains a paucity of evidence concerning how human capital could influence the organization’s ERM. Based on the Resource-based view (RBV) theory, this study analyses the correlation between ERM, human capital, and performance in Malaysian public listed companies (PLCs). For this study, 500 questionnaires had been distributed, and 116 responses were obtained. Structural Equation Modeling (SEM) had been used to assess the fitness of the conceptual model. This study found a significant relationship between ERM and organizational performance, and this relationship is moderated by human capital. This study contributes to the ERM literature by providing empirical evidence on the relationship of ERM, human capital, and organizational performance. Findings from this study also provide guidelines for managers, policymakers, and the regulatory bodies to evaluate the ERM practices in PLCs.

Penggunaan bahan bakar di indonesia masih didominasi oleh bahan bakar fosil yang ketersediannya semakin  menipis. Oleh karena itu, perlu adanya upaya untuk mengurangi/meminimalisir konsumsi energi yang berasal  dari fosil. Bioetanol merupakan salah satu jenis biofuel yang dijadikan bahan bakar alternatif. Bioetanol diproduksi  melalui proses fermentasi dari bahan-bahan nabati. Bioetanol dapat digunakan sebagai bahan campuran  biopremium sehingga dapat menghemat cadangan minyak bumi. Dalam pembuatan bioetanol, produk yang  dihasilkan masih berupa campuran alkohol dengan nomor karbon 1-5 yang harus dipisahkan dengan metode  distilasi sehingga diperoleh alkohol dengan kemurnian yang tinggi. Pemilihan metode distilasi karena dapat  digunakan pada berbagai konsentrasi dan dapat menghasilkan kemurnian yang tinggi. Produk bawah dari proses  distilasi berupa air dan fusel oil yang mengandung komponen tert-butanol dan 1-pentanol. Pengetahuan tentang  kesetimbangan uap-cair dari campuran komponen-komponen yang akan dimurnikan diperlukan dalam  perancangan proses distilasi. Berdasarkan National Institute of Standards and Technology (NIST), data  kesetimbangan uap-cair sistem biner tert-butanol + 1-pentanol masih belum diteliti. Dalam upaya mengatasi  kekurangan data tersebut, data kesetimbangan uap-cair tert-butanol + 1-pentanol sistem biner akan diprediksi  dengan permodelan UNIFAC. Kemudian, data kesetimbangan yang didapat dikorelasikan dengan perhitungan  model Universal Quasi-Chemical (UNIQUAC). Dari hasil prediksi kesetimbangan uap-cair sistem biner tert-butanol  (1) + 1-pentanol (2), azeotrop tidak terbentuk pada sistem tersebut dan diperoleh nilai deviasi dari temperatur antara hasil prediksi UNIFAC dengan perhitungan UNIQUAC memiliki nilai rata-rata yang kecil yaitu sebesar 0,1310  K.

Pencemaran air akibat limbah cair berwarna merupakan masalah serius. Masalah ini disebabkan oleh limbah  tersebut tidak dapat terurai secara alami. Salah satu metode yang mudah digunakan dalam pengolahan limbah  adalah dengan cara adsorpsi menggunakan arang aktif yang dibuat dari limbah tempurung kelapa. Arang aktif  ini dibuat dari arang hasil proses pirolisis dan diimplementasikan untuk menyerap warna pada limbah cair  berwarna. Penelitian ini bertujuan untuk mengetahui pengaruh suhu pirolisis dan konsentrasi aktivator larutan NaCl terhadap kualitas arang aktif dengan memperhatikan proses pirolisis yang dilakukan pada variasi  suhu 300℃, 325℃, dan 350℃ selama 120 menit. Lalu diaktivasi dengan larutan NaCl sebesar 30%, 35%, dan 40% selama 24 jam. Variasi suhu pirolisis dan konsentrasi aktivator tersebut dapat ditentukan kualitas arang  aktif yang baik dalam penyerapan limbah cair berwarna dengan proses adsorpsi. Berdasarkan penelitian yang  telah dilakukan, kualitas arang aktif (sesuai SNI.06-3730-1995) yang dipengaruhi oleh suhu pirolisis dan  konsentrasi aktivator larutan NaCl memberikan pengaruh terhadap penurunan warna limbah. Hasil penelitian  menunjukkan arang aktif terbaik dihasilkan pada suhu 325oC dengan konsentrasi aktivator larutan NaCl 35%,  daya serap warna pada limbah cair berwarna terbaik sebesar 99,78%.

Nira mentah tebu merupakan bahan baku dari produksi gula yang didapatkan dari hasil perasan batang tebu  pada stasiun penggilingan. Kejernihan nira ini menjadi acuan dalam kualitas produk gulanya, sehingga harus  ditambahkan susu kapur dalam proses penjernihannya. Tujuan dari penelitian ini adalah untuk mengetahui  pengaruh volume susu kapur terhadap nilai pH nira dan volume endapan yang terbentuk. Proses pengendapan  campuran nira dengan susu kapur ini selama 10 menit. Variasi pH yang ditentukan antara lain 8.5; 8.6; 8.7; 8.8;  8.9 dan pH 9 dimana dalam setiap pH dilakukan 3 kali percobaan sehingga terdapat 18 sampel yang dapat diteliti. Hasil dari penelitian ini didapatkan volume susu kapur berkisar antara 2.8-5.5 ml untuk menaikkan nilai  pH nira, sementara volume endapan yang terbentuk berjumlah nilai 9-22 ml, sehingga dapat ditarik kesimpulan  bahwa semakin banyak volume susu kapur yang ditambahkan maka pH nira mentah tebu akan semakin mendekati basa dan volume endapan yang terbentuk juga semakin banyak.

Generally, height and weight measurements are carried out separately as well as to determine the Body Mass Index must be calculated manually using specific formulas that not everyone understands, so it is difficult to know whether the body has reached a normal number or not. This study will provide suggested solutions to support the body to be healthy in measuring devices and android applications, for height measurement using ultrasonic sensors, weight using loadcell sensors and NodeMCU ESP8266 as data processors. The results of measuring height and weight appear on an LCD, the results of Body Mass Index (BMI) and the recommended solutions to meet standard body numbers in calculating BMI appear on the android application. Based on the results of the tests carried out, it is known that designing a measuring instrument with NodeMCU ESP8266 based on Android has been successfully carried out. The measuring instrument by implementing the Ultrasonic Sensor HC-SR04 as a height measurement can perform a success percentage of 96.95% and Loadcell Sensor as a weight measurement can perform the percentage of success is 98.97%, while in measuring Body Mass Index (BMI) can do a success percentage of 90.84%, the measuring instrument can also emit sound in the form of body condition in accordance with the measurement results obtained by the microcontroller with a success percentage of the sound output of 100% but has an average percentage of voice output delay variations of 2.1 seconds.
Antara Pengetahuan Dan Penetapan Allah

The study of God is never finished, because it can only be investigated through the data that has been revealed in the Bible. All is in the form of approaches with arguments which of course will continue to be debated. However, ideas are still needed to formulate a position between knowledge and God's determination. In the Old Testament, the prophets foretold about God's future plans, using the perfect form or translation. Even though this has not happened yet, the prophets use the perfect form or have indicated that the things that have been said will surely happen. The things that God has ordained impossible will not happen.

Abstrak Indonesia

Studi tentang Allah memang tidak ada selesainya, karena hanya bisa diselidiki melalui data-data yang telah diwahyukan saja. Semua berupa pendekatan-pendekatan dengan argumentasi yang tentu akan terus bisa diperdebatkan. Namun demikian tetap perlu menggali demi merumuskan posisi antara pengetahuan dan penetapan Allah. Dalam Perjanjian Lama para nabi menubuatkan tentang rencana Allah di masa depan, dengan menggunakan bentuk perfect atau diterjemahkan telah. Padahal hal ini belum terjadi, namun nabi-nabi menggunakan bentuk perfect atau telah untuk menunjukkan bahwa hal-hal yang telah disampaikan tersebut, pasti akan terjadi. Hal-hal yang Allah telah tetapkan tidak mungkin tidak akan terjadi.

Hereditary angioedema with C1 Inhibitor deficiency (C1-INH-HAE) is caused by a constellation of variants of theSERPING1gene (n= 809; 1,494 pedigrees), accounting for 86.8% of HAE families, showing a pronounced mutagenic liability ofSERPING1and pertaining to 5.6%de novovariants. C1-INH is the major control serpin of the kallikrein–kinin system (KKS). In addition, C1-INH controls complement C1 and plasminogen activation, both systems contributing to inflammation. Recognizing the failed control of C1s protease or KKS provides the diagnosis of C1-INH-HAE.SERPING1variants usually behave in an autosomal-dominant character with an incomplete penetrance and a low prevalence. A great majority of variants (809/893; 90.5%) that were introduced into online database have been considered as pathogenic/likely pathogenic. Haploinsufficiency is a common feature in C1-INH-HAE where a dominant-negative variant product impacts the wild-type allele and renders it inactive. Small (36.2%) and large (8.3%) deletions/duplications are common, with exon 4 as the most affected one. Point substitutions with missense variants (32.2%) are of interest for the serpin structure–function relationship. Canonical splice sites can be affected by variants within introns and exons also (14.3%). For noncanonical sequences, exon skipping has been confirmed by splicing analyses of patients' blood-derived RNAs (n= 25). Exonic variants (n= 6) can affect exon splicing. Rare deep-intron variants (n= 6), putatively acting as pseudo-exon activating mutations, have been characterized as pathogenic. Some variants have been characterized as benign/likely benign/of uncertain significance (n= 74). This category includes some homozygous (n= 10) or compound heterozygous variants (n= 11). They are presenting with minor allele frequency (MAF) below 0.00002 (i.e., lower than C1-INH-HAE frequency), and may be quantitatively unable to cause haploinsufficiency. Rare benign variants could contribute as disease modifiers. Gonadal mosaicism in C1-INH-HAE is rare and must be distinguished from ade novovariant. Situations with paternal or maternal disomy have been recorded (n= 3). Genotypes must be interpreted with biological investigation fitting with C1-INH expression and typing. AnySERPING1variant reminiscent of the dysfunctional phenotype of serpin with multimerization or latency should be identified as serpinopathy.
