Sensor networks constitute a scientific revolution in the field of communication and embedded systems. They continuously recorda huge amount of data that containsuncertaindata because of low battery power, network transmission problems, and noise. Sensor networks raise the challenges related to analyzing streaming data to handle unreliable and incomplete data. The sensor data are annotated to enrich the contextual information. The fuzzy logic can capture the uncertainty problem as it replaces the crisp recordings of sensors by fuzzy values. This paper proposes a framework to analyze the streaming Electrocardiogram (ECG) signals from Body sensor networks (BSNs), according to ECG features, for detecting types of cardiac arrhythmias. It is relying on OWL2 fuzzy ontology and fuzzy inference system.From our experimental results, the accuracy of the proposed framework is 97.33% using the collected dataset from PhysioBank.

Objective. The aim of the study was to evaluate the effect of subcutaneous form of methotrexate (metoject - MTJ) on the structural and functional characteristics of the vascular wall in patients with rheumatoid arthritis (RA).\nMaterials and Methods. 94 patients with RA corresponding to ACR (1987) or ACR/EULAR (2010) classification criteria, positive for IgM rheumatoid factor (RF) and/or antibodies to cyclic citrullinated peptide (ACCP) were selected. Visualization of the carotid arteries with the definition of the local rigidity of the vascular wall, as well as the study of regional arterial stiffness, including an evaluation of the contour analysis of the pulse wave, were performed before treatment and after 12 months of therapy.\nResults. It was established that patients with RA had subclinical damage of main arteries, showing the increase in the intima-media thickness (IMT) and stiffness index of the common carotid artery, indices of augmentation (AIp), stiffness (SI) and reflection (RI), the values of which correlated with the duration of RA, DAS28 activity index, RF level and ACCP concentration. The use of MTJ in patients with RA was accompanied by a statistically significant decrease in DAS28, reduction of carotid IMT and local (carotid) rigidity of the vascular bed. More significant changes were identified in the group of RA patients with disease duration of up to 2 years, in whom the regression of IMT was 29% (p<0.01), and stiffness index of the common carotid artery on average decreased by 22.5% (p<0.05) to the end of follow-up. According to the contour analysis of the pulse wave, after 12 months of treatment with MTJ decrease of AIp, SI and RI indices was observed in patients with RA, mostly in the group with RA duration of up to 2 years - in this group the mentioned parameters reached the values of the control group; in late RA those parameters decreased in average in 1.7 times (p<0.01), 1.3 times (p<0.01) and 1.8 times (p<0.05), respectively. \nConclusion. MTJ therapy, along with high anti-inflammatory activity, demonstrates vasoprotective effect, which is characterized by the reduction of signs of remodeling of the common carotid artery and regional arterial stiffness.

The purpose of this study was to conduct a meta-analysis that shows the influence of fiber on ultimate compressive strength and tensile strength of ultra-high performance concrete. The internet scholarly search engines and ScienceDirect article references were used to illustrate the papers concerning the experimental investigations of mechanical properties of ultra-high strength concrete with and without fiber with clearly, completely and comparative raw data. The normal concrete test results were dismissed from this search. Seven trials were identified based on the adopted inclusion and exclusion criteria above. The meta-analysis based on standardized mean difference was carried out on the basis of a fixed-effects model for the major outcomes of the ultimate compressive and tensile properties of ultra-high performance concrete. A total of 888 test specimens were enrolled in these seven trials. The combined analysis yielded a sign of a significant improvement in ultimate compressive strength and tensile strength of ultra-high strength concrete with fiber addition of 2% by concrete volume. The summary effect size of ultimate compressive strength was 2.34 while a more improvement in term of tensile strength with effect size of 2.64. By addition fiber of 2% provides a significant benefit in mechanical properties of ultra-high performance concrete.

This study evaluated the effects of harvesting time and husk on the proximate composition of boiled orange maize hybrids. Eight fresh orange maize hybrids were boiled with and without intact husk at 100oC using atmospheric cooking method and evaluated for proximate components. The results of analysis of variance [ANOVA] revealed that maturity [harvesting time] and method had significant effects [p ≤ 0.001] on all proximate components. There was a general decrease in dry matter [DM], ash and total sugar contents across harvest maturity stages. Protein and fat increased at 20DAP and 27DAP and then decreased at 34DAP. The unprocessed maize had optimum sugar content at 20DAP and optimum protein and fat contents at 27DAP. The optimum sugar and protein contents were found at 20DAP and 34DAP respectively for boiled maize without husk, while optimum sugar and protein contents were found at 20DAP for boiled maize with husk. Boiled maize with husk had higher retention of protein, total sugars and starch at 20DAP than boiled maize without husk. Thus, the best harvesting time to consume boiled maize is at 20DAP for optimum protein and sugar contents and it must be boiled with husk.

To investigate the food habits, food preference, feeding time and behavior of freshwater turtle Pangshura smithii, with respect to seasonal temperature change under captivity, one year trial was conducted in District Bahawalpur Pakistan. Adult freshwater turtle P. smithii were divided into three groups i.e. carnivorous, herbivorous and omnivorous. Temperature of pond water was calculated weekly. A total of 125 food items were applied on the land area and inside the water. It was observed that they feed only in water or when they partially submerged into the water. P. smithii are omnivorous but they prefer fruits more happily than vegetables and meat. They bite to each other for food and no social behavior was seen during feeding. They start to feed in first week of March at an average temperature of 19.72 oC and stop to feed in the mid of December at an average temperature of 19.28 oC. In the remaining winter months they want to burrow themselves either on land or under the water for hibernation. Ecdysis occurred from the month of early July to last of August and had no effect on feeding behavior.

– Internet of Things (IoT) connects thousands of everyday use objects and devices under the same network. Hence, Software Defined Networking (SDN) is crucial in evolving IoT. SDN provides a programmable and adaptive networking through the use of dedicated central controller that can handle a multitude of different connected devices. Integrating SDN into IoT can enable intelligent routing, simplified data acquisition, transition, and analysis, centralized management of network resources and applications, and dynamic on-demand reconfiguration of the network. At the same time, they pose challenges in terms of performance, interoperability, scalability, reliability and security. In this paper, we present a comprehensive survey on SDN for IoT, i.e., the concepts of SDN-IoT and their impact on each other, several SDN-IoT architectures, security and privacy implications, and other challenges.

Objective: To assess the chemotherapeutic effect of Allyl disulfide (garlic extract) on 1, 4-Dioxane-induced hepatocarcinogenesis in BALB/c mice. Methods: Mice were divided into four groups; group I was taken as negative control and injected with olive oil, group II was injected with Allyl disulfide once in a week for 12 weeks. 1, 4-Dioxane was given to the animals of Group III and IV respectively for 12 weeks (once in a week) followed by post treatment with Allyl disulfide once in a week for 4 week more for group IV only. At the end of the treatment, mice were dissected and blood was collected for isolation of plasma, which was analyzed for enzymes activities. Liver was taken from each animal and was analyzed for the preparation of saline, cholesterol, nucleic acid and protein extract followed by histological studies. Results: Mice treated with 1, 4 Dioxane resulted in significant increase in the plasma levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Estimation from liver homogenate also showed significant increase in ALT AST, RNA, DNA and soluble Proteins level. However, post treatment with Allyl disulfide was shown to ameliorate the 1, 4-Dioxane induced changes in liver and plasma, as indicated by the normalization of the marker enzymes, RNA, DNA and soluble Protein level. Furthermore, Allyl disulfide treatment was demonstrated to prevent the histopathological changes associated with 1, 4-Dioxane. Conclusion: In conclusion, Allyl disulfide exhibited chemotherapeutic effects against 1, 4-Dioxane induced liver carcinogenic changes, which may be attributed to its antioxidant and anti-carcinogenic activity.

This work studied the mycobiota of soils have been subjected to various anthropogenic impacts. It was found that the nature of anthropogenic impact contributes to the formation of the mikocomplexes of soils with a specific numerical and species composition as well as the ecological-trophic linkages. In addition, the anthropogenic impact on the soils, including the oil and pertroleum products, not only violates their physical and chemical structure, but also impairs the phytosanitary situation.

The hierarchical Detailed Value Chain Model and Elementary Management Cycle model of educational domain knowledge content updating is formally described and computerized process measures are proposed. The paper provides a method for updating the knowledge of the analyzed domain, referred to as “enterprise domain”, based on enterprise modelling in terms of management information interactions. A method, whose formal DVCM and EMC descriptions are provided in BPMN notation, was designed, allowing to develop a two-level (granular) model for describing knowledge of educational domain management information interactions. In implementing this model and its algorithms in technological terms, a subsystem of enterprise knowledge has been created in a knowledge-based CASE system (computerized knowledge-based IS engineering), performing the function of a domain knowledge database.

Aim. Determine resistance profiles of Shiga Toxigenic Escherichia coli strains isolated from the foodshops in Guerrero, Mexico. Material and methods. 180 samples of Mexican fast food from different corner shops in Guerrero., Mexico, were studied and analyzed on the phenotypic and genotypic basis, the resistance profile of seventy isolated strains. Results. Samples included chicken, cheese and beef. The most frequently isolated bacteria; Enterobacteriaceae (71%) that set included Enterobacter sp (40%), Klebsiella sp (26%), Salmonella sp (4%), Escherichia coli (22%), and other gramnegative bacillus (8%). Notably, 81.8% of the E. coli strains were recovered from cheese-containing food and all were positive in the amplification of the stx1 and stx2 genes by PCR; however, only 54% of STEC were eaeA gene positive. In concordance with the stx genes profiles, 57% of STEC strains were tetracycline resistant. Conclusions.The results suggest that Escherichia coli [STEC] appear to be pathogenic for humans. Finally, the data evidenced cheese as a principal food vehicle of pathogenic STEC, suggesting that the public policy on food safety must be applied.
