Economic Freedom on Stock Market Performance and Liquidity: Evidence from KSE-100 Index Pakistan

We aimed to find the effect of economic freedom on equity market liquidity and performance. Data is collected for variables for the period 2000-2017. To identify the relationship between variables, we utilize the cointegration approach. The cause and effect relationship is identified with the Granger Causality approach. We have found a direct significant impact of economic freedom and KSE-100 Index return, market capitalization, and trading volume. We observe no causality between economic freedom and return from the stock market. Furthermore, we find long-term effects of economic freedom on stock market performance and its liquidity. Additionally, we find that GDP growth, interest rate, and inflation have a causality with market capitalization, stock market index, and trading volume. The study suggests a cross-sectional analysis using multiple countries' data with a large sample set.
Comparison of the Physical Characteristics and GC/MS of the Essential Oils of Ocimum basilicum and Ocimum sanctum

Essential oils of two medicinal plants of genus Ocimum, Ocimum basilicum and Ocimum sanctum, were compared for physical characteristics, iodine values, flavour tests, sodium/potassium levels and GC/MS. The density and refractive index (1.6368) of the essential oils of O. sanctum was more than that of O. basilicum essential oils. O. basilicum essential oils were dextro-rotatory, whereas, O. sanctum essential oils were levo-rotatory (-0.044o). Hydro-distillate of O. sanctum essential oil showed greater viscosity (26.75 g -1 .cm.s) and fluidity was found to be greater for O. basilicum hydro-distillate (0.070 g.cm -1 .s - 1 ). The results of the essential oils of both the plants were same for flavour substances tests. The sodium/potassium levels of methanol extract of both the plants were 0.01 ppm and for n-hexane extract it was 0.00 ppm. Iodine value was found to be greatest for the n-hexane fraction of O. basilicum (3375.54) Besides many other constituents, GC/MS analysis showed the presence of fluorene, benzonitrile, m-phenethyl-,9H-fluorene, 9-methylene-, propanamide, N-(3-methoxyphenyl)-2,2- dimethyl- for the first time in the essential oils of both plants.
Products and Kinetics of Glucomannan Pyrolysis

The pyrolysis of particles of glucomannan, the main component of softwood hemicelluloses, is investigated in a fluidized-bed reactor. A first set of experiments is carried out for temperatures in the range 530–690 K to determine yields and composition of products. The most abundant are char, water, and carbon dioxide. The condensable organic fraction mainly consists of acetic acid, formic acid, hydroxypropanone, hydroxyacetaldehyde, and furfuryl alcohol. The second set of experiments is made to determine the weight loss characteristics of small samples exposed in the expanded bed at temperatures of 503–593 K that are then used to develop one- or two-stage pyrolysis mechanisms.
Performance Study of Vapor Compression Refrigeration System using Different Refrigerant Mixtures: Numerical Analysis

Binary refrigerant mixture, a mixture of two refrigerants, is used rather than a single refrigerant in a refrigeration system to increase the performance and energy efficiency. In the present study, in pursuit of finding a better alternative refrigerant, numerical analysis of five types of mixtures, namely R600a-R134a, R152a-R600a, R290-R600a, R600a-R717 and R134aR152a in a vapor compression refrigeration system (VCRS) has been done. The selection was based on the potential risk to the environment caused by the binary mixture. Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) were the key factors of consideration in terms of environmental risk. The analysis tool used for the computations in the VCRS was Aspen HYSYS. For each case, a particular composition of a single refrigerant mixture was considered in this refrigeration system. The refrigeration effect (RE), compressor work (Win), coefficient of performance (COP), dew point (Tdew), bubble point (Tbubble) and temperature glide (ΔTglide) were calculated with respect to the molar fraction and mass fraction of a single refrigerant. The calculations were performed with the help of few predefined parameters: composition of the mixture, condenser temperature, mass flow rate of the refrigerant mixture, pressure rise in compressor and pressure drop in expansion valve. Based on the results of the investigation, it can be declared that among these five mixtures, R600a-R290 mixture gave the best COP. But maximum COP was obtained for pure R600a. On the basis of temperature glide, it was found that except for the R152a-R134a mixture, all of the remaining four mixtures behaved as zeotropic mixtures.
Investigating Sustainability of Social Enterprises in Vulnerable Regions: The Case of Baitul Qiradh Baiturrahman in Aceh

This paper aims to provide empirical evidence on the ability of organization to survive and continue their operations in providing financial services for poor people in vulnerable regions resulting from separatist rebellions, military operations and/or natural disaster. This study departs from the assertion that organization respond to their environment on the basis of perceived problems or concerns. The paper builds on a qualitative case study at the Baitul Qiradh (House of Loan) Baiturrahman (BQB) in the specific territory of Aceh, Indonesia. This study examines how BQB can survive and grow despite operates in the difficult socio-economic and political situation, with no support and supervision from the government. Therefore, the paper presents the descriptive development of BQB from its emergence during the conflict, its growth during the post-conflict period and its resurgence after the tsunami disaster that had affected the lives and livelihoods of millions of Acehnese. Through the adoption and analysis the various stages of the organisational life-cycle, this paper provides evidence that sustainability organisation operates in vulnerable areas such as during war and/or post-natural disaster is dependent on the context specific factors such as history, socio-cultural aspect, and the politico-economy situation.
High Level Synthesis for the Cray XD-1 System in a Grid Environment

: The rapid increase in integrated circuit densities, with the slowing in the increase in commodity CPU clock rates, has fostered the investigation of hybrid architectures using FPGA technologies to provide some specialized accelerated computational capability, such as the Cray XD-1 system. In order to take full advantage of the FPGA enabled nodes of the Cray XD-1 system, and avoiding the traditional problematic development times typical of custom digital circuit design, High Level Synthesis (HLS) methodologies appear to be a promising research avenue. An HLS allows one to obtain a synthesizable VHDL description, in a near automated way, starting from a specific algorithm given in some High Level language (such as the ANSI C). In this presentation we describe the using of the HLS methodology developed by Ylichron S.r. l. – a spin-off company of the Italian Agency for the New Technologies, the Energy and the Environment (ENEA) – to implement a library of core algorithms utilizing the FPGA module of the XD-1 system. In order to further promote the using of such powerful computing platform, the XD1 system has been embedded within the ENEA Grid environment. As illustrative test case to show the advantages achievable through the adoption of reconfigurable devices we implemented a parallel solution, coded in C+MPI, of the Low Autocorrelation Binary String optimization problem; the solution boosted by the FPGA devices configured to compute the cost function of the optimization process was characterized by a speed-up factor S=19 with respect to the case in which FPGAs were not used.
COST EFFECTIVENESS OF LATENT TUBERCULOSIS SCREENING AMONG ASYLUM SEEKERS IN STOCKHOLM

Introduction The burden of tuberculosis (TB) in Sweden is concentrated among migrants from high TB incidence countries. The incident cases in Sweden arise mainly through reactivation of a latent tuberculosis infection (LTBI) acquired in the home country or during transit. Progression from LTBI to active TB disease can be prevented through treatment with anti-tubercular medicines. LTBI screening is therefore offered for asylum seekers and refugees in Sweden as part of a voluntary health examination (HE). Little is known about their experiences of LTBI screening and treatment. In addition, there has been no previous evaluation of the cost-effectiveness of the current LTBI screening policy in Stockholm or
Software and Hardware implementation of an Invariant Feature detector

This work present the results obtained during the design and implementation, in software and hardware (VHDL), of an Invariant Feature Detector. The implementation of proposed hardware architecture on a Xilinx Virtex-4 FPGA and its evaluation are presented. The software implementation of the detector, which was made in order to test easily our detection algorithm, is also presented. A framework for performance evaluation of feature detectors and descriptors is proposed. The main goal of this work is to achieve a trade-off between hardware resources and performance (in terms of invariance to certain transformations), in the design of the feature detector in hardware.
Effects of Modified Square-Stepping Exercise on Heart Rate Variability and Body Fat in the Elderly

ABSTRACT Sawasdee C, Auvichayapat P, Punjaruk W, Leelayuwat N, Tunkamnerdthai O. Effects of Modified Square-Stepping Exercise on Heart Rate Variability and Body Fat in the Elderly. JEPonline 2020;23(6):41-52. The purpose of this study was to evaluate the effects of modified square-stepping exercise (MSSE) training on heart rate variability (HRV) and body fat in the elderly. Forty-three older subjects were each randomly allocated to either the Training Group (TG) (n = 22) or the Control Group (CG) (n = 21). Subjects in the TG performed MSSE for 30 min·d, 3 d·wk for 12 wks; whereas, the subjects in the CG had no exercise intervention. Outcome variables of HRV and body fat were assessed before and after the study period. None of the parameters differed significantly between the two groups at baseline and there was no statistical change in the CG after the study period. After undergoing training, the TG showed significant decrease in biceps, triceps, subscapular, and suprailiac skinfold thickness (P<0.05). In addition, triceps, subscapular, and suprailiac skinfold thickness that had changed in the TG also differed significantly from those in the CG (P<0.05), except for biceps skinfold thickness. However, variables of HRV in time and frequency domains did not change significantly after the intervention nor did they differ significantly between the two groups. These results indicate that the MSSE training decreases body fat in the elderly.
Synthesis of 1-isopropyl-4,7-dimethyl-3-nitronaphthalene: An experimental and theoretical study of regiospecific nitration

In this work, we were able to achieve a total regioselectivity for the nitration at C3 position of 1-isopropyl-4,7-dimethylnaphthalene. The structures of the nitro isomers obtained were established by 1 H, 13 C NMR spectroscopy and confirmed using singlecrystal X-Ray diffraction. In parallel, a computational study has been performed in agreement with the experimental results obtained. With this purpose, all the σ-complexes of the five nitro isomers neutral and protonated were optimized both in gas phase by using the B3LYP/6-31(d,p) level of computational theory.

Electrochemical Adsorption Properties and Inhibition of Brass Corrosion in Natural Seawater by Thiadiazole Derivatives: Experimental and Theoretical Investigation

The electrochemical behavior of brass in natural seawater in the absence and presence of thiadiazole derivatives, namely, 2-amino-5-(4-methoxyphenyl)-1,3,4-thiadiazole (AMOPTD), 2-amino-5-(4-methylphenyl)-1,3,4-thiadiazole (AMPTD), 2-amino-5-(4-pyridinyl)-1,3,4-thiadiazole (APTD), and 2-amino-5-(4-nitrophenyl)-1,3,4-thiadiazole (ANPTD), has been investigated by electrochemical techniques such as potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The optimum concentration of the studied inhibitors showing the highest inhibition efficiency was also evaluated at five different temperatures in the range between 303 and 343 K. The inhibition efficiency was found to increase with increase in concentration of the inhibitors but decrease with rise in temperature for all the studied inhibitors except ANPTD. Thermodynamic and kinetic parameters for the adsorption process were determined. Quantum chemical approach was further used to calculate some electronic properties of the molecule in.
A proposal for run-time checks on command execution order of software program

In this paper, we proposed a method to automatically perform “inspection of control flow” of a computer program at runtime. “Inspection of control flow” is an inspection of whether the commands of the program under inspection are executed in the intended order. This inspection system targets programs that are written in assembler language and whose command execution order is determined based on input data. Normally, the program to be executed is an object program written in machine language. However, it is difficult to directly handle the machine language expressed in binary numbers. Therefore, the assembler language that has a one-to-one correspondence with the machine language and is expressed by alphanumeric characters and symbols is used for this paper. The proposed system used a learning system to automatically increase the amount of text information. The performance of this system was compared to a conventional inspection method from the input/output relationship. The proposed system detected 80% of the errors detected by the input / output relationship method.
Service Quality, Customer Satisfaction and Customer Loyalty in Nepalese Restaurant Industry

This study determines the service quality dimensions and their influence on customer satisfaction and customer loyalty in the Nepalese restaurant industry. The research is intended to examine the relationship between service quality, customer satisfaction, and customer loyalty using structural equation modeling. A positivist quantitative approach has been used to assess the impact of service quality on customer satisfaction and customer loyalty. The data is gathered from 490 students in Nepal by using structured questionnaires, and the theoretical model is tested by analysis of moment structure (AMOS-SEM). The convenience sampling technique was used to select a sample for the study. Moreover, convergent validity and discriminant validity were assessed. The results show that all dimensions have a strong positive effect on customer satisfaction, while consumer satisfaction has a positive and substantial influence on customer loyalty.Findings indicate that service quality plays a very important role in every society, as it has become the basis for how customers interpret hospitality service and, in the end, how it interacts and operates with restaurant services. This research adds up considerably to the literature of hospitality marketing, and it is also fruitful for the academicians since it demonstrates the way restaurant service quality determinants predict satisfaction of clients which ultimately raises the loyalty of clients. This study is useful for those restaurant owners and managers who want to grab markets. This research suggests a model that ultimately enhances customer loyalty towards hospitality service quality through customer satisfaction in Nepal.
Trade Credit Financing: Substitution and Matching Effect for Italian SMEs

This study investigates the relevance of financial motivation in the use of trade credit for Italian SMEs in the 2005-2012 period. Using GMM models, the study aims to test whether accounts payable follow a model of partial adjustment and whether firms that grant trade credit to their customers demand delayed accounts payable from their suppliers. It also aims to find empirical evidence that supports the financial function of trade credit. The results support the hypothesis of the existence of a model of partial adjustment, since the accounts payable terms of the previous year affect the accounts payableterms of the following year. The results also show howfirms that grant extended payment terms to their customers demand delayed accounts payable from their suppliers. The empirical evidence reveals the existence of a substitution function between accounts payable and debts to banks and suggests that SMEs increase their accounts payable when shortor medium-long-term bank credit is less available.
Free Vibration Analysis of Sandwich Beams with FG Face Sheets Based on the High Order Sandwich Beam Theory

In this paper, the vibration behavior of the sandwich beams with functionally graded face-sheets is investigated based on the high order sandwich beam theory. The properties of the FGM are varied gradually across the thickness of the structures in accordant with the power-law rule. First-order shear deformation theory and polynomial patterns are used to model the displacements of the facesheets and the core, respectively. The governing equations of the motion are obtained based on Hamilton’s energy principle and solved by a Galerkin method. An algebraic method is used to reduce the number of equations. Boundary conditions are considered as simply supported and clamped. The effect of the power-law index and geometrical variations are surveyed on the fundamental frequency parameter for different sandwich beams in some numerical examples. In order to verify the results of the present study, they are compared with special cases of the literature.
WHO IS ENGAGED IN E-WOM? ROLE OF E-LOYALTY, DEMOGRAPHICS, VISIT FREQUENCY AND PRODUCT CATEGORY

Consumers tend to share their post-purchase experiences (WOMWords of Mouth) with others regardless of whether the experiences are positive or negative. With the advancement of internet technology, WOM behavior has shifted to online platforms (eWOM) and eWOM has become an extremely effective way of communication. The main purpose of this study is to unveil the antecedents of eWOM behavior. In this respect, the role of e-loyalty in addition to demographics and other relevant factors such as e-retailer visit frequency and consumer’s mostly purchased product online in eWOM behavior was examined. A total of 296 individuals were accessed beginning from January 2019 to February 2019 through online convenience sampling. IBM SPSS 22 statistical software was used and multiple regression models was applied. The independent variables were able to explain the eWOM behavior with a R2value of.42. Compared to participants who belonged to 36-45 age group, younger participants were less likely engaged in eWOM behavior. Consumers who mostly purchased books, CDs, and electronic goods were more likely engaged in eWOM behavior, compared to consumers making apparel purchases online. Finally, findings also revealed that the less the consumers visited online e-retailers, the less these eWOM behaviors were displayed.
Introduction to shared frailty Cox models with parametric and non-parametric distributions and their application in medical data

In survival data, it is typical for survival times to be clustered or depend on some unobserved covariates. This can be due to geographical clustering, subjects sharing common genes, specific socioeconomic level, or hereditary and racial characteristics, and other predisposition that cannot be measured and observed directly. Adjusting the effects of these unknown factors on the survival functions is necessary for the independence of survival times and the explanatory variables. The aim of this study is to introduce and compare Cox models with parametric and non-parametric shared frailty on brain stroke survival data. The results showed that non-parametric frailty model has better fitting than parametric distributions (AIC=4686 and BIC=4684), especially when the exact parametric distribution is not known. According to the results of best model, following variables were statistical significant; BMI (HR=0.97, P=0.045); Age (HR=1.04, P<0.001); HDL (HR=1.01, P<0.001); LDL (HR=0.99, P<0.001); Hyperlipidemia (HR=0.72, P<0.014). The nonparametric frailty is desirable, due to potential misspecification of the parametric form and as a method for detecting clusters of groups with similar frailties.
ManipNet

Natural hand manipulations exhibit complex finger maneuvers adaptive to object shapes and the tasks at hand. Learning dexterous manipulation from data in a brute force way would require a prohibitive amount of examples to effectively cover the combinatorial space of 3D shapes and activities. In this paper, we propose a hand-object spatial representation that can achieve generalization from limited data. Our representation combines the global object shape as voxel occupancies with local geometric details as samples of closest distances. This representation is used by a neural network to regress finger motions from input trajectories of wrists and objects. Specifically, we provide the network with the current finger pose, past and future trajectories, and the spatial representations extracted from these trajectories. The network then predicts a new finger pose for the next frame as an autoregressive model. With a carefully chosen hand-centric coordinate system, we can handle single-handed and two-handed motions in a unified framework. Learning from a small number of primitive shapes and kitchenware objects, the network is able to synthesize a variety of finger gaits for grasping, in-hand manipulation, and bimanual object handling on a rich set of novel shapes and functional tasks. We also demonstrate a live demo of manipulating virtual objects in real-time using a simple physical prop. Our system is useful for offline animation or real-time applications forgiving to a small delay.
