Operating Task Redistribution in Hyperconverged Networks

In this article, a searching method for the rational task distribution through the nodes of a hyperconverged network is presented in which it provides the rational distribution of task sets towards a better performance. With using new subsettings related to distribution of nodes in the network based on distributed processing, we can minimize average packet delay. The distribution quality is provided with using a special objective function considering the penalties in the case of having delays. This process is considered in order to create the balanced delivery systems. The initial redistribution is determined based on the minimum penalty. After performing a cycle (iteration) of redistribution in order to have the appropriate task distribution, a potential system is formed for functional optimization. In each cycle of the redistribution, a rule for optimizing contour search is used. Thus, the obtained task distribution, including the appeared failure and success, will be rational and can decrease the average packet delay in the hyperconverged networks. The effectiveness of our proposed method is evaluated by using the model of hyperconverged support system of the university E-learning provided by V.N. Karazin Kharkiv National University. The simulation results based on the model clearly confirm the acceptable and better performance of our approach in comparison to the classical approach of task distribution

Remarks on the rings of functions which have a finite numb er of di scontinuities

[EN] Let X be an arbitrary topological space. F(X) denotes the set of all real-valued functions on X and C(X)F denotes the set of all f ∈ F(X) such that f is discontinuous at most on a finite set. It is proved that if r is a positive real number, then for any f ∈ C(X)F which is not a unit of C(X)F there exists g ∈ C(X)F such that g ≠ 1 and f = gr f. We show that every member of C(X)F is continuous on a dense open subset of X if and only if every non-isolated point of X is nowhere dense. It is shown that C(X)F is an Artinian ring if and only if the space X is finite. We also provide examples to illustrate the results presented herein.Department of pure Mathematics Yazd university.

IoT-Based Smart Management of Healthcare Services in Hospital Buildings during COVID-19 and Future Pandemics

The paper aims to design and develop an innovative solution in the Smart Building context that increases guests' hospitality level during the COVID-19 and future pandemics in locations like hotels, conference locations, campuses, and hospitals. The solution supports features intending to control the number of occupants by online appointments, smart navigation, and queue management in the building through mobile phones and navigation to the desired location by highlighting interests and facilities. Moreover, checking the space occupancy, and automatic adjustment of the environmental features are the abilities that can be added to the proposed design in the future development. The proposed solution can address all mentioned issues regarding the smart building by integrating and utilizing various data sources collected by the internet of things (IoT) sensors. Then, storing and processing collected data in servers and finally sending the desired information to the end-users. Consequently, through the integration of multiple IoT technologies, a unique platform with minimal hardware usage and maximum adaptability for smart management of general and healthcare services in hospital buildings will be created

Tel: 034335229985 Email: [email protected] Abstract: Introduction: The presence of committed human resources improves organizational performance and achievement of individual and organizational goals. The objective of this study was to investigate the relationship between organizational commitment and job burnout among staff of the selected hospitals affiliated to Kerman University of Medical Sciences. Methods: This cross-sectional, descriptive-analytic study was carried out in 2015. In this study, 278 employees were selected using quota sampling. In order to collect data, Maslach questionnaires on job burnout (22 questions) and Allen & Meyer organization commitment questionnaire (24 questions) were used. Data analysis was performed through SPSS 16 and using descriptive statistics as well as analytical statistics tests such as Pearson correlation, ANOVA and linear regression. Results: In whole, 74.8% of the participants were female and 40% had less than 10 years of work experience. Mean scores of organizational commitment (98.20) and job burnout (74.58) were in moderate level. Organization commitment and all its dimensions had significant inverse relationship with job burnout (P=0.000). In addition, the relationships of organization commitment with gender and age, and job burnout with employment status were significant (P=0.01). Conclusion: High organizational commitment represents the acceptance of organizational goals and values by the employees. Committed employees have better job performance in the organization and less job burnout. Therefore, managers must attempt to raise the level of organizational commitment and put it in their programs planning.

Relationship between the Presence of the nalC Mutation and Multidrug Resistance in Pseudomonas aeruginosa

Objectives. The current study was conducted to determine the relationship between the presences of significant multidrug resistance in Pseudomonas aeruginosa (P. aeruginosa) having intact mexR genes (nalC) to different antibiotics. Methods. In order to identify nalC, fifty strains of P. aeruginosa were obtained. All isolates were found in urinary tract infections. They were evaluated against different antibiotics. The nalC mutant was identified by PCR. Results. The 50 clinical isolates of P. aeruginosa originated from two hospitals in Iran, in which 32 isolates were found in Milad hospital, and 18 isolates were collected in the Ilam Hospital. The results in Milad hospital of nalC revealed that all P. aeruginosa resistant to oxacillin showed the presence of nalC. In Ilam hospital only three (16.6%) isolates were resistant to oxacilin and aztreonam, and among these three isolates only one isolate revealed resistance to ceftazidime and amikacin. The resistant isolates showed the presence of both OXA-10 and nalC. Conclusion. Our results showed that the presence of nalC was observed among P. aeruginosa resistance to oxacilin. Thus, the finding suggested relationship between oxacilin resistance and presence of nalC and consequently overproduction of the MexABOprM efflux system

Modelling of proteolysis in Iranian brined cheese using proteinase-loaded nanoliposome

In this study, Flavourzyme was encapsulated in liposomes to accelerate the ripening of Iranian white cheese. Liposomal enzyme was prepared using a modified heating method. The influence of enzyme content, ripening time and curd retention in saturated brine on proteolysis indices and sensory perception was investigated using response surface methodology. The most influential factor on proteolysis indices was ripening time, while the content of liposomal enzyme and retention time were also significant (P < 0.05). The maximum proteolysis indices and highest sensory characteristic scores were achieved by applying 0.3% w/w enzyme, ripening for 30 days and 8-h curd retention in saturated brine
