GROWTH, FOOD UTILIZATION RESPONSES AND SURVIVAL RATE OF INDIAN MAJOR CARP, LABEO ROHITA (HAMILTON) FINGERLINGS UNDER EXPOSURE OF COW URINE DISTILLATE

Objective: The study evaluated the effect of Cow Urine Distillate of different breeds on the growth performance and food utilization of Indian major carp Labeo rohita fingerlings.Methods: Fishes were exposure with different CUD in medium at 0.1% (v/v) as C (Without CUD), T1 (Gir), T2 (Haryana), T3 (Holstein Friesian cross bred) for seven days, a study was conducted. Various growth, food utilization parameters and mortality were examined at 10, 20 and 30 days of post-exposure of CUD.Results: The results showed that Gir CUD was more effective to compare with Haryana and HF cross bred CUD. The maximum growth rate of 0.0160 mg/day-1 was observed in the Labeo rohita fingerlings treated with Gir CUD treated fingerlings when compared with control. The maximum feeding rate of 0.0039 mg/body wt-1/day-1 was observed in the same group. Survival rate of 90% was observed in the same treated group when compared with 60% survival rate in control.Conclusion: Our results indicate that growth parameter and food utilization parameter values were increased significantly due to CUD exposure while comparing with control group. In addition, levels of growth rate, Feed Conversion Rate, Percentage increased body weight and Specific growth rate were also increased in the treatment groups.     Â

Ontologies for specifying and reconciling contexts of web services

This paper presents an ontology-based approach for the specification (using OWL-C as a definition language) and reconciliation (using ConWeS as a mediation tool) of contexts of Web services. Web services are independent components that can be triggered and composed for the satisfaction of user needs (e.g., hotel booking). Because Web services originate from different providers, their composition faces the obstacle of the context heterogeneity featuring these Web services. An unawareness of this context heterogeneity during Web services composition and execution results in a lack of the quality and relevancy of information that permits tracking the composition, monitoring the execution, and handling exceptions. © 2006 Elsevier B.V.

Decoupling security concerns in web services using aspects

This paper discusses the Aspect-oriented Framework for Web services (AoF4WS) that supports on-demand context-sensitive security in Web services. Flexible security schemes are needed in many Web services applications where authentication, authorization, etc., can no longer be used in their current form. Security mechanisms are to be customized to the continuously changing requirements of Web services. Examples of this customization concern cryptographic protocol for a specific situation and timeout for user credentials. The AoF4WS uses aspect-oriented programming and frames. Aspects provide flexibility to the framework, and frames adjust aspects to specific requirements. © 2006 IEEE

Context-driven policy enforcement and reconciliation for Web services

Security of Web services is a major factor to their successful integration into critical IT applications. An extensive research in this direction concentrates on low level aspects of security such as message secrecy, data integrity, and authentication. Thus, proposed solutions are mainly built upon the assumption that security mechanisms are static and predefined. However, the dynamic nature of the Internet and the continuously changing environments where Web services operate require innovative and adaptive security solutions. This paper presents our solution for securing Web services based on adaptive policies, where adaptability is satisfied using the contextual information of the Web services. The proposed solution includes a negotiation and reconciliation protocol for security policies

A PROSPECTIVE STUDY OF CLINICAL PROFILE OF STROKE IN A TERTIARY CARE HOSPITAL

ABSTRACTObjective: The objective of the work was to study the clinical profile of stroke in a tertiary care hospital.Methods: A prospective observational study on stroke was carried out for a period of 6-month (May 2015 to October 2015). A total of 241 inpatientsfrom Shri Preethi Hospital were incorporated in the study. The data were collected and evaluated by reviewing case files and patient interview.Result and Conclusion: Out of 241 patients, an incidence of ischemic stroke was found to be higher. The occurrence of stroke steeply rises with agewith male predominance. The burden of stroke tends to be more in rural, illiterate, and low socioeconomic status population. The study reveals riskfactors such as sedentary lifestyle, previous and family history of stroke, underlying disease like hypertension, diabetes. The circadian pattern in onsetshowed a significant peak in morning (6 am-12 pm) for Ischemic and afternoon (12 pm-6 pm) for hemorrhagic stroke. Topographic distribution ofcerebral infract and hemorrhage was found to be in parietal lobe and periventricular white matter, respectively. Mostly prescribed medication forischemic and hemorrhagic patients was antihypertensive and mannitol, respectively. The contraindication for thrombolytic therapy was found to below economic status and average delay in time of presentation to hospital. The study highlights the need for aggressive management of traditionalrisk factors, need for extensive work up in patient to find etiologies and need for more active interventions in community for the prevention of stroke.Keywords: Ischemic, Hemorrhagic, Circadian pattern, Antihypertensive

Towards an ontology-based approach for specifying and securing Web services

With the increasing popularity of Web services and increasing complexity of satisfying needs of users, there has been a renewed interest in Web services composition. Composition addresses the case of a user request that cannot be satisfied by any available Web service, whereas a composite service obtained by integrating Web services might be used. Because Web services originate from different providers, their composition faces the obstacle of the context heterogeneity of Web services. An unawareness or poor consideration of this heterogeneity during Web services composition and execution result in a lack of the quality and relevancy of information that permits tracking the composition, monitoring the execution, and handling exceptions. This paper presents an ontology-based approach for context reconciliation. The approach also focuses on the security breaches that threaten the integrity of the context of Web services, and proposes appropriate means to achieve this integrity. © 2005 Elsevier B.V.
