SUITABILITY OF BI-VACANCY TRAP FOR TL EMISSION IN KCl

In KCl crystals, the 2s energy level of F-center within an anion-cation vacancy pair has been proposed as a suitable trap for thermoluminescence (TL) emission. It is further seen that the 2s – level of F-center situated in cation – anion vacancy pair has large trap depth. The observed trap depth of F-center is explainable on the basis of Herman and Barnett model, modified presently and supports bi-vacancy configuration for traps in KCl lattice.
Application of Novel Features in Complex Network for Analyzing Virtual Community

Virtual community (VC) arises rapidly and influences many aspects of human life styles in real world. Differentiated from traditional way to advertise products/services, VC also enables consumers to participate in interaction activities related to products via threads, learn greater insight about products in deep level while improve consumer loyalty. Most of the extant research did not emphasize or lack of effective methods on how to gain deep learning of product and explain the uniformity of users’ importance in VC. In this paper, based on knowledge in complex network, generalised variance of degree in directed network is proposed to ascertain uniformity of directed network, which is an innovative methodology. Research conclusions can guide enterprises more in-depth understanding of the complex network theory and its application to social network analysis (SNA) with big data streams.
INTELLIGENT SYSTEMS AND APPLICATIONS IN ENGINEERING

: Social media is like a revolution since it has changed many things in people’s lifestyles by bringing new trends in communication, shopping, working…etc. Inspired by the importance of social media, we propose Opinion Leader Detection (OLED) system in this paper. OLED has two main parts. In the first part, the tweets were labeled with their categories by semantic kernels for topic-based analysis. We run these semantic kernels and their variants with SVM in our experiment environment. After LDA and these semantic classifiers, obtain category information for each tweet in the dataset. OLED’s second part attempts to detect whether the users are opinion leaders in their category. Then, the leadership scores are calculated with the formula generated and opinion leaders are determined in each category. The purpose of OLED is to find the opinion leaders for each category. In other words, OLED aims to detect opinion leaders for different topics such as Economy, Culture-Art, Politics, Sports and Technology. We performed our experiments on a real data collection gathered from Twitter that includes 17,234,924 tweets and 38,727 users. The language of the dataset is Turkish. Users with highest scores are stated as opinion leaders. In order to evaluate OLED’s performance, we also run PageRank algorithm on the same dataset. We also compare our study to one of the existing studies in the literature. The experimental results show that our framework OLED generates remarkable performance in compare to PageRank algorithm nearly in all topics and all selected top number of opinion leaders.
THE EFFECT OF CAPITAL STRUCTURE AND FINANCIAL STRUCTURE ON FIRM PERFORMANCE (An Empirical Study of The 2008 and 2009 Financial Crisis in Indonesia)

This research aims to identify the impact of capital structure on Indonesian firm performance, particularly the magnitude of the impact at the periods prior, during, and following the crisis that occurred in 2008. The Global Financial Crisis grants a chance to scrutinize the impact of crisis between capital structure and firm performance. The proxies used for capital structure are total debt to total assets, short-term debt to total assets, and long-term debt to total assets ratio. In addition, firm performance is measured by accounting performance (Return on Asset and Return on Equity) and market performance (Price to Equity Ratio and Tobin’s Q). Samples in this study include all firms listed on the Indonesian Stock Exchange (IDX) from the period of 2004 until 2017, excluding firms from the financial sector. This research posits that capital structure generally negatively impacts firm performance . The 2008 Global Financial Crisis (GFC) serves a greater negative impact of capital structure on firm performance than before and after the crisis. This research is intended for use by firms as a perusal in managing capital structure, for creditors in managing lending, and for investors in investing, especially in times of financial crisis.
Organizational Project Management Maturity Effect on the Relationship Between Entrepreneurial Orientation and Organizational Performance in Egyptian Organizations

This paper explores the effect of Organizational Project Management Maturity (OPMM) on the Relationship Between Entrepreneurial Orientation and Organizational Performance (EO-OP) in Egypt. The research foundation of this paper is the Resource-Based View (RBV) theory. Data was collected from senior managers from 244 Egyptian organizations and regression analysis, ANOVA testing and a series of moderated hierarchical multiple regression analysis were used to test the hypotheses. The results revealed that the relationship between EO and OP is much more dependent on the organizational context and environment and that OPMM has positive effect on OP and antecedent effect on EO.
Emission Characteristics of Agricultural and Industrial Cellulosic Wastes Blended with Gasoline

Agricultural and industrial wastes like sawdust and corncobs are definitely pollutants as they are disposed in dump sites and burnt in open air in most developing countries, like Nigeria. Proper utilization of these wastes could help reduce the environmental pollution arising from wastes disposal and combustion of fuels. Emissions generated from running an internal combustion (IC) engine with blends of gasoline and bio-ethanol produced from these wastes, as well as those of pure gasoline were compared in this work. A gas emission analyzer was placed at the exhaust of the IC engine and the readings were taken for each blend and for each round of testing period. The read out emissions were then compared with each other. Â The range of emissions for carbon monoxide (CO) were 1.45-2.75; 2.10-2.90; 2.00-2.62 and 3.0 % vol., for corncobs bio-ethanol/gasoline, softwood sawdust bio-ethanol/gasoline, hardwood sawdust bio-ethanol/gasoline and pure gasoline samples respectively while the emission ranges for hydrocarbon (HC) were 260-435; 328-360; 313-350 and 480 ppm for the same samples respectively. In the case of carbon dioxide (CO2), the samples gave 2.6-4.0; 2.2-3.9; 3.2-4.2 and 3.0 % vol. emissions. Thus all stakeholders considering the adoption of fuel blends in the countryâ€™s quest for increased energy mix can be properly guided on the pollutants associated with the investigated waste materials. This may help in the choice of appropriate waste to energy.
ORIGINAL ARTICLE

Background and objectives: Diabetes mellitus is the most common endocrine disorder and the leading cause of death and disability in the world. Magnesium is the most common intracellular cation involved in insulin mediated glucose uptake. This study was conducted in type 2 diabetic patients to assess fasting blood glucose (FBS), HbA1c and serum magnesium levels and compare it with normal controls. Materials and Methods: This was a case control study which included 50 patients with type 2 diabetes mellitus and 50 healthy controls. Serum magnesium was estimated by calmagite endpoint method. HbA1c was estimated by immunoturbidimetry method. Statistical analysis was done using SPSS. Results and discussion: Decrease in mean level of serum magnesium were observed among diabetic patients. A negative correlation was observed between serum magnesium and HbA1c. A linear regression analysis showed an inverse relationship between serum magnesium and glycemic control among patients with diabetes mellitus. Conclusion: We concluded that type 2 diabetic patients who are at risk of developing microvascular complications with poor glycemic control must be regularly monitored for serum magnesium levels.
Mechanism and Motivation

In the past, literature about the government's influence on corporate tax burden have studied corporate tax avoidance from the perspective of tax colection and management, while few have examined corporate tax avoidance from the perspective of policy formulation and policymakers. This paper fils this gap. Government is an empty concept, and its policy characteristics are actualy the reflection of real core government officials' decision-making. By referring to Bertrand and Schoar (2003), Dyreng, Hanlon, and Maydew (2008), this paper finds that individual factors of financial leadership have a significant impact on the level of income tax rates of companies in their jurisdictions. Furthermore, the formulation of the financial budget is the influence path, including the proportion of local general budget revenue in local GDP, the proportion of local general budget expenditure in local GDP, the proportion of local tax revenue in local GDP, and the proportion of local enterprise income tax in al tax revenue. Finaly, this paper finds that the leaders' motivation for their future careers is the influence of corporate tax avoidance. The characteristics that impact corporate income tax are the tenure of the director of finance, age, and whether the next post is promoted to the vice governor or vice mayor.

Received 21 May 2020 Revised 21 Jun 2020 Accepted 30 Nov 2020 A kind of bimetallic Zn/Co zeolitic imidazole frameworks (ZnCo-ZIFs) was successfully synthesized from 2-methylimidazole and two metal salts including zinc nitrate, cobalt (II) nitrate by a solvothermal method at room temperature. Subsequently, Ag nanoparticles (AgNPs) loading on bimetallic frameworks were prepared by a facile impregnation method in acetone solvent. Both ZnCo-ZIFs and Ag/ZnCo-ZIFs were analyzed by several characterization techniques including powder X-ray diffraction (PXRD), scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA) and energy-dispersive Xray spectroscopy (EDX). The results showed that ZnCo-ZIFs crystals had sodalite structure, high thermal stability, and AgNPs were successfully loaded on the ZnCo-ZIFs with content of 18.42%. Ag/ZnCo-ZIFs in this combination may pave a way for preparing a kind of heterogeneous catalyst to remove organic compounds from aqueous solutions. Keywords
Antioxidant, Antimicrobial and Cytotoxic Potential of Abelmoschus esculentus

Abelmoschus esculentus is an important medicinal plant belongs to family Malvaceae. It originates from Ethiopia and is widely spread all over tropical, subtropical and warm temperate regions of the world. This research work has been designed to evaluate the antioxidant, antimicrobial and toxicological potential of A. esculentus leaves and seeds. The antifungal and antioxidant components of A. esculentus leaves and seeds were extracted by using four solvent systems (80% methanol, 80% ethanol, 100% methanol and 100% ethanol) and leaves presented maximum extract yield (38.1 g/100g DW)in 80% methanolic solvent system. Phytochemical analysis of A. esculentus leaves and seeds extracts performed in terms of total phenolic and total flavonoid contents, showed that 80% methanolic leaves extract offered highest total phenolic contents (31.2 mg GAE/g DW), whereas 80% ethanolic leaves gave maximum total flavonoid contents (41.8 mg CE/g DW). Antioxidant activity was determined by DPPH radical scavenging activity and measure of reducing power. Results revealed that 80% methanolic leaves extract showed highest radical scavenging activity and reducing potential. Antimicrobial activity of A. esculentus leaves and seeds was investigated by Disc Diffusion Method and Minimum Inhibitory Concentration (MIC). Results showed that 80% methanolic extract of leaves exhibited highest antibacterial and antifungal potential against P. multocida (30 mm DIZ) and A. paraciticus (29 mm DIZ), respectively. Cytotoxicity analysis was performed on BHK-21 cell by adopting the MTT assay. The cytotoxicity activity of the 80% methanolic extract of leaves was evaluated by noticing the cell survival percentage (52.5%). Overall results of the present study showed that 80% methanolic leaves extracts of A. esculentus possesses very good antioxidant, antimicrobial and cytotoxic properties.
EFFECT OF ELECTRONIC HEALTH INFORMATION SYSTEM ON MEDICAL RECORDS MANAGEMENT IN PUBLIC HEALTHCARE INSTITUTIONS

The worrisome state of Nigerian hospitals in the last decades owing to continued to adopt the global trend on information systems to move away from healthcare delivery characterised by inefficiencies, poor management practices evidenced by continuous use of the traditional paper record system in most public health facilities in Nigeria, which often time causes delay and long patient waiting time, resulting in cases of infant and maternal mortality. Hence, this study investigated how an electronic health information system can improve medical records management in Nigeria’s public healthcare institutions. The study employed the numerical and qualitative research philosophy, adopted the survey and case study research strategies, the cross-sectional and qualitative research designs. The study sample covered 332 respondents spread across four selected Federal Medical Centres in Makurdi, Keffi, Lokoja and Abuja FCT, all located in the North Central Region of Nigeria. In the collection of primary data, the researcher took cognisance of ethnic consideration regarding the confidentiality of data and protection of respondents’ trust. The study used the simple frequency percentage table to analyse collected data. The finding revealed that, though there is still heavy reliance on traditional paper-based records system, however, adoption of eHIS will reduce risk of treatment errors, decrease patient waiting time, enhance timely communication among practitioners, protects patient information from unauthorised personnel and enhance healthcare service delivery. The study, therefore, recommended that the government and hospital management should prioritise the provision of necessary infrastructure in the health capital budget to support adoption and implementation of the electronic health information system and electronic medical records management to reduce high mortality rates from delayed treatments and preventable medical errors.
Potential protective Effects of okra aquatasextract against the complications of diabetes mellitus in rats

The current study aimed to use different concentrations of okra aquatas extract(OAE) (15,30and 45g/100ml), in addition to whole and residues mashed okrain feeding induced diabetes rat groups for six weeks. Such groups were biologically and histopathologically compared with another negative and positive group. The proximate chemical composition as well as fiber fractions (crude,neutral detergent and acid detergent) and some minerals (Ca,Mg and Fe) of okra pods were also studied. Organoleptic evaluation of OAE was also assessed by diabetic patients. The results indicated that significant differences (P ≤ 0.05) were noted between body and organs weight especially heart and spleen of rats fed on OAE diets in comparison with the other groups. In addition, OAE enhanced insulin secretion and lowered glucose level. Also, OAE lowered TG, LDL and VLDL while the HDL, liver and kidney functions improved. Pancreatic histopathological examination showed that groups fed on OAE (30,45g/100ml) seemed to be close to the negative control group with no histopathological changes in relative to the other diabetic rat groups. The results also showed that diabetic patients preferredOAE (30g/100ml). In general addition of OAE in diets could be managed of diabetes through improve liver and kidney functions as welledpancreashistopathological.
Green Skills and Sustainable Economy in Kenya: The Influence of TVET Trainer Competencies

Greening Technical and Vocational Education Training (TVET) is an initiative of the United Nations Educational, Scientific and Cultural Organization (UNESCO) together with, the International Centre for the Technical and Vocational Education and Training (UNEVOC) that requires Technical and Vocational Educational Training Institutions to provide knowledge and develop skills that ease transition to green economies and societies. In an effort to attain the Sustainable Development Goals, the Kenyan government has revamped TVET institutions with both human and non-human resources. There is no doubt that green skills hold the future for sustainable economies, however, the role of trainers cannot be gainsaid. The study analyzed the influence of trainers’ competencies on the relationship between green skills and sustainable economy. The study adopts the ‘ex-post facto’ design based on the post-positivist paradigm to sample 200 pre-existing technician graduates drawn from Uasin Gishu County. Data was collected using questionnaires and structured interview schedule which yielded both quantitative and qualitative data for analysis. Descriptive and inferential analyses revealed that the four green skills namely attitudes, values, knowledge and technical skills positively and significantly predicted sustainable economy. There is therefore need to focus on building the capacity of TVET trainers in order to inculcate the required green skills among trainees. This will largely contribute to enhancing sustainable development competences and thus implementing the Sustainable Development Goals for green economies and societies.

Landslide-lake outburst floods accelerate downstream slope slippage

Abstract. The Jinsha River, carving a 2–4 km deep gorge, is one of the largest SE Asian rivers. Two successive landslide-lake outburst floods (LLFs) occurred after the 2018 Baige landslides along the river. Using Sentinel-2 images, we examined the LLFs' impacts on downstream river channel and adjacent hillslopes over a 100 km distance. The floods increased the width of the active river channel by 54 %. Subsequently, major landslides persisted for 15 months in at least nine locations for displacements > 2 m. Among them, three moving hillslopes, ~80 km downstream from the Baige landslides, slumped more than 10 m one year after the floods. Extensive undercuts by the floods probably removed hillslope buttresses and triggered deformation response, suggesting a strong and dynamic channel-hillslope coupling. Our findings indicate that infrequent catastrophic outburst flooding plays an important role in landscape evolution. Persistent post-flood hillslope movement should be considered in disaster mitigation in high-relief mountainous regions.
Selected methodological approaches to the hypothetical application of the valuation of cultural heritage to historical monuments

Selected methodological approaches to the hypothetical application of the valuation of cultural heritage to historical monuments. Cultural heritage has signifi cant meaning for society and represents different values for each person. This is the reason why valuing it causes so many diffi culties. There are not many publications on the subject, which is probably because of the many methodological problems. These include a lack of data and the limited nature, in the sense that they concentrate on specifi c national policies, of existing case studies. However, the similarity between environmental and cultural goods gives researchers an opportunity to transfer some of the valuation methods applied to the environment to cultural heritage. This paper presents selected valuation techniques and the hypothetical problems associated with applying them using the example of Polish heritage in the form of historical monuments. Though further studies are required, the results delivered by the economic approach may be of merit in the valuation of cultural heritage.
Kinematics Modeling and Motion Planning of Tendon Driven Continuum Manipulators

Continuum manipulators have important applications in the human–machine interaction fields. The kinematics, dynamics, and control issues of the continuum manipulators are rather different from a conventional rigid-link manipulator. By the aid of Lie groups theory and exponential coordinate representations, the kinematics of the continuum manipulators with piecewise constant curvatures and actuated by tendons is investigated in this paper. On the basis of differential kinematics analysis, the complete Jacobian of the continuum manipulators is derived analytically, and then a new motion planning approach, named as “dynamic coordination method” is presented for the multisegments continuum manipulators, which is a class of superredundant manipulators. The novel motion planning approach is featured by some appealing properties, and the feasibility of the modeling and the motion planning method is demonstrated by some numerical simulations.
