Nowadays, due to their widespread application, various models of bioelectrical impedance analysis (BIA) devices have become available. However, differences in multiple parameters among these BIA devices pose a significant challenge despite their common underlying principle. The primary aim of this research was to assess the correlation, agreement, and differences in specific body composition parameters-body fat percentage (BF%) and muscle mass percentage (Muscle%)-measured by three distinct BIA devices (Omron BF300, Omron BF511, and InBody 770). Measurements were conducted by the same examiner, on the same day, in a sample of 35 women aged between 21 and 26 years. Participants’ baseline characteristics (age, body height, body mass, body mass index) were recorded, alongside their body composition values (BF% and Muscle%) obtained using the three, i.e. two BIA devices, respectively. Data analysis employed SPSS 26.0 software, applying descriptive statistics, Pearson’s correlation coefficient, concordance coefficient, repeated measures ANOVA, paired sample t-test, and Bland-Altman plots. Results demonstrated statistically significant correlations (p=0.000) for BF% across all three BIA devices, and for Muscle% between Omron BF511 and InBody 770. Additionally, a significant correlation (p=0.000) with high concordance was noted (W=0.939 for BF%, W=0.926 for Muscle%), although significant differences among devices were also evident (p<0.001). Given the absence of a universally accepted reference method and considering the prior validation of InBody devices against DXA, the InBody 770 is recommended for accuracy when possible. However, for field assessments requiring portable solutions, the Omron BF511 is preferred due to its practicality in terms of size, weight, and portability.
The purpose of this paper is to adapt Technology Acceptance Model (TAM), which is one of the models for adopting technological products, into technological product purchase behavior of consumer, and to test the moderator effects of technology readiness, the direct effects of which were examined in the previous studies, through the model. In order to test the relations included in the model Hierarchical Regression Test were conducted. As a result, the moderator effects showed that as the consumers’ insecurity towards a technological product and their discomfort in using the product increase, the effect of brand credibility on both perceived usefulness and perceived ease of use decreases.
The objective of this paper was to explore the relationship among conflict management, personality types and emotions. Conflict management is one of the key behaviors of an organization. Since it is investigated that everyone has a unique personality, so possibly to handle a conflict-based situation would also differ. The other main feature identified in this study was emotions. The current study aims to identify the relationship of personality and emotions with conflict-management patterns within hoteliers in Pakistan. Thus the present study carries the selection of two independent variables personality types specifically type A and emotions in relation with conflict management being the dependant variable. The sample of research consisted of fifteen major hotels in Pakistan comprising 290 employees as total. To fulfill the research purpose, Self-report structured and referenced questionnaires were used to assess the research variables. When personality types and conflict management was assessed, significant interaction was found. Emotions were found to have both positive and negative effect on conflict management. A series of regression analyses as well as correlation analysis were carried out in the research. A range of different approaches to explore these issues such as how different personality types are related with conflict management and how emotions (either positive or negative) play their important role in handling conflicts are discussed. Furthermore, limitations and recommendations are also being discussed that influence the relationship of conflict management, personality types and emotions of hoteliers differently.

This research highlights the significance of preventing, finding out and treating diabetes mellitus (DM) from early stages of on set. The late finding of diabetes mellitus leads to both medical and economic losses. The treatment of the complications of the diabetic disease raises the costs of the care and the losses due to patient missing from work cannot be neglected. The expenses with diabetes mellitus have constantly increased everywhere in the world. The highest costs for a diabetic patient raised to 13,243 USD/patient/year, in 2002, in the USA – the highest ever recorded costs of this disease. The estimations made by International Diabetes Federation show that, in 2012, the cost for diabetic patients care reached 471 billion USD, in the world, and 138.8 billion USD, in Europe. A study carried out in Europe in 2008, showed that hospitalization costs represent almost 60% of the total costs of diabetes mellitus treatment, outpatient care costs 18.5% and drug therapy represents 21.7%. In Romania, the treatment of diabetes mellitus is free of charge. The funds allotted by the Ministry of Health for the Diabetes Programe in the time interval 1999-2012 increased 25 times, but Romania ranks among the top ten countries with diabetes cases in Europe.
In order to better understand how to prevent enzymatic greenning, it is important to\nunderstand kinetic properties of polyphenol oxidase. vegetable markets projected for the\nfuture will not occur if enzymatic greenning is not understood and controlled. We\ninvestigated the effect of SDS on the rate of catechol oxidation by wild pears partial\npurified PPO. PPO activity increased with increasing SDS concentration. The most\neffective concentration of SDS was 0.9 and 1 mM in according to pH and type of\nsubstrate, where the measured activity was 782 and 3200 units/mg.protein at pH 5 and\n380 and 1100 unit/mg.protei.n at pH 7 for catechol and pyrogallol, respectively at 1 mM\nSDS. The activation of pears PPO increased linearly with the SDS concentration up to 1\nmM and decreased thereafter. The activity of pear PPO was also enhanced 2.6-fold by\nexposure to SDS at pH 5.0 in presence of catechol, 3.7-fold by exposure to SDS at pH\n5.0 in presence of pyrogallol, 1.7-fold by exposure to SDS at pH 7 in presence of catechol\nand 1.7-fold by exposure to SDS at pH 5 in presence of pyrogallol. SDS has activating\neffect on polyphenol oxidase in presence of both dihydroxy and trihydroxy phenols, So\nthat, this activating effect at pH 5 is more than activating effect at pH 7.
Abstract:\nThe vast and growing need of society to the building and housing has raised the necessity of using construction systems and new construction materials in order to accelerate construction operation, reduce construction cost, increase quality and also retrofitting and strengthening buildings resistant against earthquake more than before.Due to the relatively vast geographical area of the developing country of Iran, and given the rapid burgeoning population and growing requirements to mass housing production, common and traditional construction methods utilization cannot meet the housing requests. So, application of modern technologies and/or construction methods by using industrial production methods is the proper response for the challenges facing the building industry of the country.

Teleradiology facilitates timely interpretation of medical images for better medical care. Observations at the referral site can help the remote radiologists make a thorough analysis. Images transferred to remote sites must be accompanied with relevant patient identifiable data to resolve identity issues when similar images are to be examined by a radiologist. In this paper, we present a zero-watermarking scheme to watermark a host image, with a Health Level 7 (HL7) message encompassing patient identifiable data and clinical readings that is encoded into a binary Quick Response (QR) code. The proposed system preserves the fidelity of the cover image as the watermark is not physically embedded. Embedding and extraction are realized with a Master Share, Secret Share and a binary QR code. In the proposed system, Master Share is created out of the sign bit sequence of the Hu’s moments, computed on selected non overlapping blocks of the host image subjected to Singular Value Decomposition (SVD). Robustness to geometric and non geometric attacks is evaluated by running attacks with different parameters with a benchmarking software. The proposed system exhibits security and robustness characteristics essential to deliver teleradiology practices in compliance with legislative standards.
Removal of Al3+ and Mn2+ from solution by Trichoderma asperellum BHU216 immobilized on Irvingia gabonensis matrix in a batch system was investigated. Effect of biosorption conditions contact time, pH, bead size and spore load were studied. Equilibrium isotherms and re-usability of biosorbent were also determined. The result showed that optimum sorption of Mn2+ and Al3+ by immobilized sorbent was achieved at 7 mm bead size and 1.6 g/L spore load. Optimum pH were 5 and 6 while equilibrium was attained at 120 and 180 mins for Mn2+ and Al3+ sorption respectively. Immobilized biosorbent was used in more than 5 batch cycles with over 50% removal achieved in 3 and 5 cycles for Al3+ and Mn2+ sorption. Brunauer-Emmett-Teller (BET) isotherm had the best-fit than both Langmuir and Freundlich isotherms for both metals (R2 0.99 and 0.97 for Mn2+ and Al3+ respectively). Manganese sorption proceeded at both surface and multi-layer levels with high sorption rates 18.88 mg/L and 19.72 mg/L, while aluminium sorption was feasible in a multi-layer process with low uptake (0.87 mg/g). This study showed that immobilized T. asperellum BHU216 can effectively act as biosorbent for Mn(II) and Al(III) sorption from solution.
Abstract: \n\nInflatable rubber dams are cylindrical rubber fabrics placed across channels, streams and weir or dam crests to raise the upstream water level when inflated. Inflatable dams can be filled with water, air or both. In this paper, an analytical model is presented for hydrostatic analysis of the dam. The model has been made and the results are compared with Alhamati et al experimental results. There is an acceptable similarity in both numerical and experimental behavior of the dam.
Abstract:\n In most of the current design codes and standards for concrete liquid storage tanks, the hydrodynamic pressures are determined assuming that the tank walls are rigid. The Housner’s model, which assumes that the mass of liquid is lumped on the wall based on rigid wall boundary condition in the calculation hydrodynamic pressure, is widely used in practice. Previous research has indicated that the flexibility of wall can affect the distribution and magnitude of hydrodynamic pressures. In this paper, the effect of wall flexibility on hydrodynamic pressures in concrete rectangular tanks is studied using an approach referred to as the sequential method. The procedure on how to establish the impulsive hydrodynamic pressures using the sequential method based on a two-dimensional analysis is described. A comparison shows that the lumped mass approach overestimates the base shear and wall displacements.
Abstract\n Background and Objective: Zarrineh Roud river which, is also named Cham Choghatoo is one of the most important and longest rivers of Euromieh Lake watershed area which, is originated from Kurdistan’s Chehel Cheshmeh Mountains and eventually pours into Euromieh Lake. One of its’ important usage is for drinking and farming which, unfortunately due to its’ pollution with different natural and man- made pollutant , makes the quality monitoring of its water under special importance and attention . In this study, we review quality of this river.\n Method: In this study we have measured 13 parameters of DO, FC, pH, BOD, changing in temperature, total phosphate, total nitrate, chloride, TDS, EC, Calcium, Sodium and Magnesium in two seasons of spring and winter of year 1389 (2011), then based on this, quality of water has been analyzed based on NSFWQI index and Wilcox method.\n Findings: In most of the times, in both seasons of spring and winter, amounts of NSFWQI index are in good range and only in two cases, in each season, index were in average range. Also based on results of Wilcox method in both seasons, majority of stations were at C2S1 range, in some cases also these amounts were at C3S1 range. Only in Station Ghale Bozorg in spring amount of salinity was in C4 range.\n Conclusion: In most cases, water of Zarrineh Roud is appropriate for farming, fish farming, animal drinking , leisure usage and drinking ( after normal filtering)
Abstract\n Shape and form of the watermelon fruits are important factors to save spaces and reducing damage during storing of the fruits. In order to save spaces and prevent fruit damage in watermelon the following experiment was carried out in the farm. The fruits were boxed when they were approximately one cm less than the box diameter. The cubic, hexagonal forms were compared in this research. To do this, different boxes were designed with different holes on the sides to holes the watermelons fruits for shaping. The shapes of the boxes were hexagonal and cubic. The boxes holes sizes were the same with 10mm diameter each. Each side of the boxes had different holes including: without holes to 75 holes. The result showed that the best shape for watermelon storing to save space and prevent fruit damage was hexagonal form. The percentages of the fruit damage were 33 to 80 respectively.
The copper-zinc superoxide dismutase gene resides on chromosome 21 and is over expressed in Down syndrome patients. Reactive oxygen species can initiate lipid peroxidation and DNA damage leading to mutagenesis, carcinogenesis and cell death, if the antioxidant system is impaired. Down syndrome is associated with various forms of thyroid dysfunction, hypothyroidism being the most common. The additive effects of both co-morbid conditions lead to further amplification of the clinical problems in the children with Down syndrome. The present work aimed to study the changes in the quantitative in vitro activities of the antioxidant enzymes – glutathione peroxidase and superoxide dismutase in the erythrocyte and thyroid stimulating hormone level of the study group. This study group included both Down syndrome patients and age, sex matched healthy controls. We found significant increase in the activities of both glutathione peroxidase and superoxide dismutase and thyroid stimulating hormone level in patients as compared with healthy controls. This study has revealed that increased antioxidant enzymes activity and thyroid stimulating hormone level are the three significant indicators of Down syndrome patients.
