    Migrating services in an edge-cloud environ- ment poses unique challenges, including heterogeneous en- vironments, potential failures, and uneven resource distri- bution. This paper studies and evaluate reactive and predic- tive migration approaches to support live migration in case of edge cloud computing failures. Telemetry information relate to edge cloud computing have been considered to trigger migration, whereas deadlock prevention algorithm has been used to determine and select the target device to migrate services. The paper evaluates these strategies by comparing resource utilization, assessing differences between predictive and reactive migration and handling multiple migrations for tenants hosting numerous appli- cations. Experimental results have shown that predictive migration can reduce the downtime of the hosted services. Additionally, the total migration cost can be increased for both scenarios where the containers can be migrated to different edge devices due to lack of available resource

    Background: With blindness normal stimulation of the hypothalamic pituitary axis is reduced. The serum cholesterol is frequently increased the upper limit of normal it is unclear whether the effect is due to complete absence of light, HPA axis function reduction or diurnal variation of melatonin levels.Methods: A self-administered questionnaire ascertained lifestyle characteristics, including alcohol consumption, cigarette smoking, diabetes mellitus and dietary habits. Inclusion criteria: 50 complete blindness persons (by birth), healthy adults, Age group between 30-50 years. Exclusion area: age 50, alcoholic, liver diseases, kidney diseases, diabetes mellitus, thyroid diseases.Results: A total No of 100 cases were studied by dividing them into two groups controls 50 and cases 50. The results so obtain were compared with 50 healthy controls (excluded consumed alcoholic, liver diseases, kidney diseases, diabetes mellitus, thyroid diseases.). Statistical evaluation was carried out to confirm any deviation from the normal values. The mean serum cholesterol of Cases (298.28±26.82) is having higher level as compared to the mean value of controls (153.38±11.79). This increase is statistically highly significant (<0.0001).Conclusions: It has been shown from this study with blindness normal stimulation of the HPA is reduced consequently the serum cholesterol is frequently increased the concentration may exceed the upper limit of normal. On this basis we observed increases the upper limit of the cholesterol levels in blind healthy people than subjects with normal healthy light perception

    Background: Although prolonged (30years) coffee consumption has been associated with reduced or increased frequency of liver (SGOT, SGPT, GGT) enzymes and cholesterol levels, it is unclear whether the effect is from coffee or caffeine.Methods: A self-administered questionnaire ascertained lifestyle characteristics, including alcohol consumption, cigarette smoking, Diabetes mellitus and Dietary habits. As for drinking habit, examinees were first asked about their current drinking frequency (none, 1-2 times/ week, or almost daily) past or current smokers about the number of cigarettes smoked per day and the duration of smoking in years. As regards coffee, examinees were asked their usual daily intake in cups.Results: A total No of 200 cases were studied by dividing them into two group’s controls and cases. The results so obtain were compared with 50 healthy controls (not to consumed caffeine contained things that include nor coffee, tea, any type of cola’s). Statistical evaluation was carried out to confirm any deviation from the normal values. In men the mean serum SGOT, SGPT, GGT and cholesterol of cases is having higher level as compared to the mean value of controls. This increase is statistically highly significant (SGOT<0.0001, SGPT=0.045, GGT=0.0043, cholesterol<0.0001). In women’s the mean serum SGOT, SGPT, GGT and cholesterol of Cases is having higher level as compared to the mean value of Controls. This increase is statistically significant (SGOT< 0.05, SGPT=0.0319, GGT <0.0001, cholesterol: <0.0001).Conclusion: It has been shown from this study that prolonged daily consumption of coffee in many people it results increasing of levels of serum concentrations of the SGOT, SGPT, GGT and Cholesterol. It is observed that liver enzymes and cholesterol could be a target for caffeine or other components of coffee.

    Web Applications are the predominant medium for not only business enterprises but also for service-based sector to establish and continue their online presence. However, the robustness of web application is mandatory in seamless interaction with customers for achieving sustainable business. Intruders and unethical hackers keep trying to gain unauthentic access to the web applications and hence it is more necessary for the web application to be resistant against any such attacks. The strength of a web application is indirectly responsible for gaining customer confidence leading to repeat business as well as attracting new customers for profitable longer run. Once the web application gains credibility it is bound to run successfully. In the current work, an attempt has been made to assess the robustness of mutation operators used to test web applications is made. A few rubrics have been proposed to ascertain the strength of projected mutation operators verified on some sample open-source web applications. The functional attributes of a web application are the functionalities offered by the web application. The non-functional attributes of a typical web application are security, performance, availability. Here, web applications are challenged against the afore mentioned non-functional attributes using rubrics like uniformity, uniqueness, reliability, unpredictability, and entropy. A comprehensive analysis has been made for the robustness of the projected web operators against the designed and formulated rubrics
