The Research Development of Respiratory Metabolism for Living Beings of Fishery Resources

[Objective]To describe the research development of respiratory metabolism for living beings of fishery resources home and abroad so as to provide reference for fishery production and management. [Method]Investigate research methods of respiratory metabolism about fish,shrimp, crab,shells and other living beings and analyze factors affecting their oxygen consumption rates and ammonia excretion rates according to research results of respiratory metabolism for living beings of fishery resources home and abroad. [Result] Respiratory metabolism is one of the important contents of bioenergetics research,an important part of energy balance research. It reflects not only the physiological status of living beings,but al- so the influence of environment condition on their physiological activities. Factors affecting respiratory metabolism are divided into biological factors and non-biological factors. By researching factors such as weight,temperature,activities,circadian rhythm,ingestion,Oxygen partial pressure and so on,we can evaluate respiratory metabolism of living beings of fishery resources. [Conclusion]Investigating from the individual physiology and e- cology to group physiology and ecology,the research provides data support for enhancement and releasing of sea ranch.

Heuristic Virtual Machine Allocation for Multi-Tier Ambient Assisted Living Applications in a Cloud Data Center

Cloud computing provides the essential infrastructure for multi-tier Ambient Assisted Living(AAL) applications that facilitate people's lives. Resource provisioning is a critically important problem for AAL applications in cloud data centers(CDCs). This paper focuses on modeling and analysis of multi-tier AAL applications, and aims to optimize resource provisioning while meeting requests' response time constraint. This paper models a multi-tier AAL application as a hybrid multi-tier queueing model consisting of an M/M/c queueing model and multiple M/M/1 queueing models. Then, virtual machine(VM) allocation is formulated as a constrained optimization problem in a CDC, and is further solved with the proposed heuristic VM allocation algorithm(HVMA). The results demonstrate that the proposed model and algorithm can effectively achieve dynamic resource provisioning while meeting the performance constraint.

Coastal zone management in India-present status and future needs

The coastal zone is a region where land,ocean and atmosphere interact and hence it is dynamic in nature.India has a long coastline which was not adequately monitored until the advent of the satellite remote sensing era in the 70s.India has a very robust remote sensing program that the Indian Remote Sensing Satellite(IRS)series of satellites were effectively used to monitor coastal habitats,landforms,shoreline,water quality,etc.,and changes were identified during the last 40 years.The classification system for coastal habitats and the classification and geometric accuracies of products were standardized.Detailed information for mangroves communities and characteristics of coral reefs were generated.The high and low tide lines were delineated seamlessly for the entire coastline using satellite data.All these data were organized in a GIS and the coastal database for the entire country was created.Impacts of various hazards on such as cyclones,tsunami and sea level changes on coastal habitats were documented.Based on topography,shoreline changes and tides,coastal multi-hazard vulnerability maps were characterized by employing the elevation data derived from satellite data and were prepared for the coastline of India.The information on ocean color and sea surface temperature was used to generate potential fishery advisories,which are provided daily to fishermen.The coastal database was utilized effectively to identify coastal regulation zones,marine protected areas,vulnerable zones,etc.Various services for tsunami,fishery and coral reef bleaching were generated for societal benefits.It is planned to develop models for the coastal zone,so that impeding dangers and likely changes in the coastal zone can be predicted and suitable actions can be undertaken.It is necessary to integrate socio-economic data with the knowledge database of coastal zone to understand the impact of anthropogenic activities and the changing climate on the coastal zone.
