Authors: Arshad Qurat-ul-Ain , Azam Faisal , Khan Wazir Zada , Khan Muhammad Khurram , Raza Mudassar
Published: March 2022

Internet of Things (IoT) vision has astoundingly transcended the environmental sensing with integrated computing systems and smart devices, providing seamless connectivity among humans, machines and their environment to cooperate for convenience and economical benefits. Apart from all the tremendous benefits of IoT, this paradigm still suffers from challenges of security and privacy vulnerabilities and demands a secure system for effective utilization of services in real world IoT scenarios relaying on which the IoT consumers expect secure and trustworthy communications. Trust Management (TM) being a crucial aspect of security, plays a vital role in ensuring the exchange of information in a secure manner and maintaining the reliability of a system by measuring the degree of trust on IoT devices, reducing the uncertainties and risks involved in the systems. Centralized TM systems for IoT have a potential risk of failure and attacks and decentralized TM systems are not completely decentralized, requiring the assistance of central servers for the completion of final calculation and maintenance of trust credits. Thus, in recent years, Blockchain technology has been utilized for developing security innovations in Trust management field for different classes of IoT applications. It can provide tamper proof data by enabling a more reliable trust information and integrity verification, ultimately enhancing its availability and privacy during storage and sharing. This paper provides a comprehensive survey that aims at analyzing and assessing Blockchain based Decentralized Trust Management Systems (BCDTMS) for IoT. In this paper, our contributions are twofold; first we provide a comprehensive comparative analysis of state-of-the-art BCDTMS devised for different IoT classes including IoMT, IoV, IIoT and SIoT. To make it an extensive study, we perform a detailed Assessment of existing BCDTMS in the literature (for last three years 2018-2020) on the basis of Blockchain and trust based aspects. Secondly, we present requirements and challenges in the context of using blockchain for TM in IoT.
UNDERWATER SOURCE LOCALIZATION USING CYLINDRICAL HYDROPHONE ARRAY AND RIEMANNIAN MATCHED FIELD PROCESSING
Authors: Quyen Tran Cao
Published: March 2022

The Matched Field Processing (MFP) is for defining the range and the depth of an underwater source effectively. However the algorithm is seldom used for finding the azimuthal direction of the source and is still not considered for multiple field replicas due to the variation of sound velocity. If using cylindrical hydrophone array (CHA) with 32x10 elements (ten ring with each ring of 32 elements) the rough azimuthal angle resolution, , is obtained. Then using TDOA (Time difference of arrival) of the two selected consecutive beams of CHA the system could provide the bearing accuracy up to . Then, the range and the depth of the source are the solution of the proposed Riemannian MFP with the assumption of cylindrical spreading. The proposed RMFP is on the basis of Riemannian distance which is calculated directly by solving the geodesic equation on cylinder surface. The simulations show that only with the data from selected vertical hydrophone array of CHA (there are 32 vertical arrays on cylindrical array) is enough to locate the range and the depth of underwater source precisely.

A Study to Compare the Efficacy of Kati Basti with Different Oils (Prasarani Oil and Moorchita Tila Oil) in Sciatica (Gridrashi)
Authors: Verma Dr. Chandra Prakash , Sahoo Dr. Sushanta Kumar
Published: March 2022

Sciatica is a painful ailment caused by the pathology of the sciatic nerve or the sciatic nerve root. Pain and paresthesia in the sciatic nerve distribution or a lumbosacral nerve root are common in patients with this condition. A herniated disc with nerve root compression is the most common cause of sciatica; however lumbar stenoses and (less frequently) tumors are also probable causes. In general, 5 to 10 percent of people with low back pain have sciatica, but the lifetime prevalence of low back pain is reported to range from 49% to 70%. Gridhrasi having the same symptomatology as sciatica described in ayurvedic classics under vata vyadhi, is a condition in which pain, stiffness, gripping, and pulsations begin in the buttocks [gluteal region] and progress to the posterior aspect of the Kati (pelvis and lumbosacral regions), Uru (thigh), Jaanu (behind the knee), Jangha (leg), and Pada (foot). Among different modalities of treatment described in Ayurveda, Kati Basti is the most popular and commonly practiced one. In the present study an effort has been made to treat 30 patients of Gridhrasi with Kati Basti with Prasarini Taila and Tila taila separately in two groups. The treatment was given 48 minute long daily for seven days. The assessment was done by analyzing the changes in clinical signs and symptoms before and after treatment. The majority of patients (93.33 percent) improved after treatment. In this study, kati basti with prasarini taila outperformed moorchita tila taila in terms of reducing Gridhrasi or sciatica signs and symptoms. The snehana property of oil and medications in Prasarini taila was helpful in the relief of gridhrasi, as well as the swedana impact of Kati Basti.

Published: March 2022

This study examines the effect of board diversity on the financial performance of manufacturing firms in Nigeria. The motivation for the study lies in the increased quest to establish the most appropriate board with the optimum mix needed to guarantee the absence of corporate failure. The study comprises of 64 listed manufacturing firms as at 31st December 2020, and sample size of 20 listed manufacturing firms were selected using purposive sampling technique. Data were obtained from annual reports of the selected firms from 2011 to 2020. Descriptive statistics and panel regression estimation techniques were used to analyze the data collected. The findings shown that board diversity has an insignificant effect on performance except for financial expertise diversity with a positive effect on financial performance, and there is a presence of long run relationship with firm performance. Based on these findings, the study therefore concludes that diversity on the board in terms of gender, ethnicity and educational background will not really improve or reduce performance of the firms while diversity in terms of financial expertise will do. Thus, it is recommended that greater measures need to be taken by manufacturing firms in Nigeria to have a higher percentage of board members with financial expertise, and directors with certified financial expertise should be allowed to stay longer on the boards to guarantee improved performance in the long run.

Authors: KI Green , Abbey Mkpe
Published: March 2022

The Niger Delta in the Southern part of Nigeria had been captioned ‘a region of environmental degradation’ including carbon monoxide (CO) pollution in the World Bank study of the region in 1995 and in the UNEP Environmental assessment of Ogoniland in 2011. The objective of the study was to ascertain the sources of CO production in the Niger Delta, the availability of Nigerian national guidelines on CO pollution, Nigerian national and regional register of CO poisoning and air quality check for CO in the region. A mixed method study (observational-descriptive and systemic review was carried out. Sources of CO production were visited, guidelines on environmental protection, CO and its register and data on daily air monitoring were looked for in Rivers State and the Nigerian Federal Ministries of Environment, Health and Justice. The result showed that there were no guidelines on environmental protection against CO pollution, no register of its poisoning and no monitoring of its ambient and indoor air concentrations in the Niger Delta. Sources of its pollution were tobacco fumes, generator, firewood, kerosene, bush and refuse burning, fire out-brake, barbecues, burning of fossil fuels in old vehicles, crude oil and gas industry (three refineries, oil wells, flow stations and gas flaring, crude oil and condensate spills, vapours from crude and refined oil storage, processing and transportation facilities, petrochemical plants and gas liquefaction plants). In conclusion the Niger Delta was plagued with numerous sources of CO emission and ineffective environmental protection laws. There was therefore urgent need for revival of regional and national environmental laws, maintenance of registers for CO poisoning and conduct of daily air quality check for CO and other gases in the Niger Delta and in Nigeria at large.

The Impact of Regional Financial Capability during the COVID-19 Pandemic towards Regional Fiscal Capacity
Authors: Kurniawan Kurniawan
Published: March 2022

Regional fiscal capacity is the region’s ability reflected in regional revenue, consisting of own-source revenue (PAD), fiscal balance transfers, and other legitimate regional revenues. This study aims at analysing the impact of regional financial capability during the Covid-19 Pandemic towards regional fiscal capacity. The research was conducted in local governments in Indonesia during 2020 using descriptive qualitative analysis. The results showed that generally the Covid-19 Pandemic affected the reduction on own-source revenue (PAD) in almost all provinces in Indonesia during the first semester of 2020. From 66 regencies/cities as the sample from this research, 49 regencies decreased in revenue and expenditure because of the Covid-19 Pandemic. The revenue reduction in each region was caused by regional taxes reduction of around 2,5 percent and 10,68 percent sequentially in the first semester of 2020, fiscal balance transfers around 8,42 percent, and general allocation grant (DAU) around 9,8 percent and 6,94 percent. Meanwhile, to solve the regional fiscal problems, the local governments implemented 2 types of policies: (1) the first policy is to implement a counter-cyclical policy through maintaining economic stability, decreasing revenues, and increasing local government expenditures; (2) the second policy is to implement a pro-cyclical policy through increasing revenues and decreasing expenditures. The present research also found that regencies/cities that implemented a counter-cyclical policy generally increased in expenditure components, such as grant expenditure around 316,51 percent and regional capital expenditure. Some local governments built infrastructure (assets and buildings) during the Covid-19 Pandemic. However, local governments decreased around -1% - 16% for the employee expenditures.

Published: March 2022

With the newly emerging concepts and advancements in genetic/genomic technologies, information on causative or candidate gene(s), transcription factors or growth factors responsible for orthodontic cases such as craniofacial dysmorphologies, morphogenesis and differentiation of craniofacial tissues, midfacial defects, crowding of teeth, prognathism, genetic variations associated with susceptibility of developing and/or heterogeneity in treatment response of malocclusions are emerging. Promising results have been accrued on utilization of genetic testing for management of monogenic traits such as primary failure of eruption (PFE), and Class III malocclusion. As the impact of genetic/genomic factors on orthodontic treatment outcome is emerging, gene therapy as a novel approach is being explored for effective and precise orthodontic treatment. Despite certain challenges and biosafety issues, the emergence of some promising success stories and ongoing research in gene therapy provides an optimistic future in the field of precision orthodontics. However, in order for precision orthodontics to be implemented in daily practice, more exquisite research is warranted. This review encompasses a conspectus on the potentials of genomics and gene therapy in achieving precision orthodontics.

Published: March 2022

Urinary tract infection is the attack of a tissue of the urinary tract by one or more micro-organisms. It is a major public health problem. The objective of this work is to propose, based on updated data, the microbial ecology of urinary tract infection at the Avicenne Military Hospital in Marrakech, and to follow the antibiotic sensitivity profile of uropathogenic bacteria. This is a retrospective descriptive study over 4 years from January 2014 to December 2018, which was conducted on urinary cytobacteriological examinations from hospitalized patients and outpatients, treated at the microbiology laboratory of the Military Hospital Avicenne of Marrakech. Of the 17607 ECBUs that were examined, the diagnosis of urinary tract infection was retained in 2349 (13%). 75% of the ECBUs came from hospitalized patients and 25% from outpatients, with a sex ratio of 1.1. The analysis of the ECBU showed that Enterobacteriaceae constituted 80% of the positive urine isolates, with a predominance of Escherichia coli (62%), followed by Klebsiella pneumoniae (13%). The reading and interpretation of the antibiograms showed that Escherichia coli was resistant to aminopenicillin associated with clavulanic acid in 51% of the cases against 55% for Klebsiella pneumoniae. The resistance of enterobacteriaceae to fluoroquinolones is about 33% for Escherichia coli, 30% for Klebsiella spp, while for the Trimmethoprim+Sulfamethoxazole combination more than half of the strains were resistant. On the other hand, aminoglycosides still have a good activity profile on enterobacteriaceae. The prevalence of BMR is 6.5%, represented by enterobacteriaceae producing extended spectrum betalactamases (ESBL) isolated in 89% of cases, with a predominance of Escherichia coli (52%) followed by klebsiella pneumoniae (22%) and Enterobacter cloacae (16%). Then the ceftazidime-resistant Pseudomonas aeruginosa (PARC) occupies the 2nd place with 5%, and finally methicillin-resistant Staphylococcus aureus (MRSA) and imipenem-resistant Acinetobnacter baumanii (ABRI) which occupy the 3rd place with rates at 3%. These BMR constitute a worrying problem, hence the need for rigorous application of hygiene rules and rational prescription of antibiotics. The knowledge of bacteriological profiles and the use of targeted antibiotic susceptibility testing will allow a management adapted to each hospital context.

MANIFESTATIONS OF EXCESSIVE DAYTIME SLEEPINESS AND GHRELIN LEVEL IN CASE OF GASTROESOPHAGEAL REFLUX DISEASE IN PATIENTS WITH UNDIFFERENTIATED CONNECTIVE TISSUE DISEASE
Authors: Romash Iryna B. , Mishchuk Vasyl. H. , Romash Ivan R. , Krasilych Iryna O. , Romash Nadiya I. , Vus Viktor I. , Kolinko Yaroslav
Published: March 2022

The aim of the study was to discover the interrelation between the severity of gastroesophageal reflux disease (GERD) symptoms, acid exposure time (AET), excessive daytime sleepiness (EDS) and the level of active blood plasma ghrelin in the patients with undifferentiated connective tissue disease (UCTD).
Materials and methods: The study included 120 patients with GERD. All the patients were divided in two groups: Group I - GERD was not accompanied by the signs of connective tissue disease (n=45) and Group II - GERD developed on the background of UCTD syndrome (n=75). Daily transnasal pH monitoring was performed to determine the nature of pathological refluxes. EDS was detected by The Epworth Sleepiness Scale. Active ghrelin in blood plasma samples was determined by ELISA.
Results: 80% of the patients of Group II and 35.48% of Group I suffered from EDS (p<0.05). The mean daily AET index was 5.48±0.4% in Group II and 6±0.2% in Group I, in the night hours mostly when patients were in the upright position. This phenomenon contributed to a deterioration of sleep quality and the appearance of EDS and was supported by a connection between AET and EDS (r=+0.827 for Group I and r=+0.768 for Group II). The mean De Meester index was higher in the patients of Group II (23.01±2.24 in Group I vs 31.08±2.4 in Group II; p<0.05).
Conclusions: GERD manifestations are strongly related to the level to AET and intensity of EDS. The EDS symptoms depend on circulating ghrelin level.

THIS paper presents two ways of calculating the load angle of a non-salient pole synchronous generator. The sine function used for calculation of the load angle of the generator considers its internal voltage, which with variable synchronous reactance introduces a double error in the calculation of the load angle. The cotangent function used for calculation of the generator’s load angle is based on its active and reactive power and its external voltage. Another goal of this paper is to present the steady-state stability of the generator with a new instability proximity index based on the cotangent function of load angle calculation. A new instability proximity index is the energy porosity defined as an approximate measure of how far the current operating state of the generator is from the state of instability. The degree of danger of the generator entering an unstable state according to the relevant electrical quantities is especially emphasized by the sensitivity coefficients based on the new instability proximity index. The key findings from this research are found in the more accurate calculation of the load angle of the synchronous generator and in connection with that the accurate estimation of the distance of the generator from the point of instability. As the more accurate load angle is that calculated via the cotangent function and which is smaller than the load angle calculated via the sine function, it is possible to load the generator more with the same degree of stability compared to the load based on the load angle calculated via the sine function. This results not only in a better safety aspect of the generator operation, but also economically, because this approach in calculating the stability of the generator enables greaterutilization of the generator capacity.
Reaction Mechanisms Testing with Spatial and Thermal Resolutions of Methane/Air Flames
Authors:   Department of Aerospace Engineering, King Abdulaziz University, Jeddah, Kingdom of Saudi  Arabia, Mohammad Akram
Published: March 2022

Spatial and thermal dispersals of hydroxyl (OH), formaldehyde (CH2O), and other minor species have been acquired using various detail reaction mechanisms in the weak flame of stoichiometric methane and air mixture at ambient pressure. The weak flame was simulated inside a microflowcombustor with a prescribed temperature profile which releases a very small amount of heat. A wide reaction zone (~ 1 cm) was observed for methane and air flames compared to normal/conventional flames. Detailed oxidation analysis was carried out based on the normal and weak flames simulations. The computational flame structure was assessed with the experimentalresults available in the existing literature. Numerical modeling under the experimental conditions with various detail mechanism predicts a similar wide reaction zone. However, the species production and consumption temperatures were observed to vary for the different mechanisms used in present studies. The GRI mech 3.0 shows a typical two-peak heat release rate profile. The initial breakdown of fuel is vital for such scatter. The production of OH radical governs the initial breakdown of fuel at the intermediate temperatures. The present investigation is pretty useful in understanding the chemistry of intermediate species for different fuel-air mixtures specially at intermediate temperatures 800–1200 K.

Authors: Bína Jan
Published: March 2022

Urbanized settlement systems "town-hinterland" have their source in nodal zones (centre settlement systems) of bigger towns. They are characterized by: (1) the deepening of nodal processes, (2) the transmission of qualitative traits of towns towards their hinterlands, (3) the growth dynamics of hinterlands. The article examines to what extent the Czechoslovak regions of Centres of District Meaning (246) can be considered as units of urbanized settlement system "town-hinterland" of elected hierarchical degree.

Lack of social presence is one of the many challenges that online education is facing right now in spite of its numerous benefits and growing popularity. While different strategies, primarily behavioral- or cognitivebased, have been proposed and adopted to improve online social presence, affect-based intervention remains a novel approach to increasing learners’ experience of connectedness. The Social Performance Optimization Tool (SPOT) is a university-funded, web-based interactive environment in which students interact with classmates through animated dog avatars that reflect their learning performance health and emotional states. This paper reports on an early, exploratory stage of research study wherein the SPOT users’ experiences of social presence are explored through interviews. Tu and McIsaac’s (2002) framework for social presence was used to analyze three dimensions of social presence: social context, online communication, and interactivity. Findings suggest that the SPOT personalizes the learning environment and helps learners feel more connected.
Exploring Different Needs of Digital Immigrant and Native Teachers for Technology Professional Development in China
Authors: Li Yi , Wang Qiu , Lei Jing
Published: March 2022

This study examined if professional development needs of digital native and digital immigrant teachers differed in order for them to successfully integrate technology into teaching in the Chinese education setting. Quantitative and qualitative data were collected from 500 teachers in six schools in the southwest of China. The digital native teachers and the digital immigrant teachers were compared in terms of their different technology use behaviors and integration skills. The findings indicated that even though the digital native teachers had greater comfort with basic technology than the digital immigrant teachers, they still required training for integrating technology effectively in their teaching. The digital immigrant teachers needed more basic technology operations training as well as connections between technologies and teaching. Future technology professional developments in developing countries should 1) consider the different needs of digital native teachers and digital immigrant teachers; 2) prepare them to make meaningful connections between technologies and their teachings; and 3) adopt individual coaching with on-site designated specialists.
