ENERGY EFFICIENT LOAD BALANCING FOR CLOUD DATA CENTER
Cloud computing is the latest trend in large-scale distributed computing. It provides diverse services on demand to distributive resources such asservers, software, and databases. One of the challenging problems in cloud data centers is to manage the load of different reconfigurable virtual machines over one another. Thus, in the near future of cloud computing field, providing a mechanism for efficient resource management will be very significant. Many load balancing algorithms have been already implemented and executed to manage the resources efficiently and adequately. The objective of this paper is to analyze shortcomings of existing algorithms and implement a new algorithm which will give optimized load balancingresult
Study of wind speed attenuation at Kavaratti Island using land-based, offshore, and satellite measurements
The role of dense coconut palms in attenuating the wind speed at Kavaratti Island, which is located in the southeastern Arabian Sea, is examined based on land-based and offshore wind measurements (U10) using anchored-buoy-mounted and satellite-borne sensors (QuikSCAT scatterometer and TMI microwave imager) during an 8-year period (2000-2007). It is found that round the year monthly-mean wind speed measurements from the Port Control Tower (PCT) located within the coconut palm farm at the Kavaratti Island are weaker by 15-61 relative to those made from the nearby offshore region. Whereas wind speed attenuation at the island is ~15-40 in the mid-June to mid-October south-west monsoon period, it is ~41-61 during the rest of the year. Wind direction measurements from all the devices overlapped, except in March-April during which the buoy measurements deviated from the other measurements by ~20o. U10 wind speed measurements from PCT during the November 2009 tropical cyclone "Phyan" indicated approximately 50-80 attenuation relative to those from the seaward boundary of the island's lagoon (and therefore least influenced by the coconut palms). The observed wind speed attenuation can be understood through the theory of free turbulent flow jets embodied in the boundary-layer fluid dynamics, according to which both the axial and transverse components of the efflux of flows discharged through the inter-leaves porosity (orifice) undergo increasing attenuation in the downstream direction with increasing distance from the orifice. Thus, the observed wind speed attenuation at Kavaratti Island is attributable to the decline in wind energy transmission from the seaward boundary of the coconut palm farm with distance into the farm. Just like mangrove forests function as bio-shields against forces from oceanic waves and stormsurges through their large above-ground aerial root systems and standing crop, and thereby playing a distinctive role in ameliorating the effects of catastrophies such as hurricanes, tidal bores, cyclones, and tsunamis, the present study provides an indication that densely populated coconut palms and other tall tree vegetation would function as bio-shields against the damaging effects of storms through attenuation of wind speed
Enabling factors for sustainable menstrual hygiene management practices: a rapid review
This paper highlights the crucial enabling factors in menstrual hygiene management. The use of products depends on various factors such as access to water, privacy, social, cultural and econmic. Gender equality and womenâs empowerment are integral parts of the Sustainable Development Goals (SDGs). Half of the worldâs population are women, and women have specific needs to manage the menstrual cycle during their lifetime. To manage the bleeding during the menstrual cycle, girls and women use different products, depending on their accessibility and affordability. They are (a) disposableâone-time use products such as disposable pads, tampons, and (b) reusable productsâreusable products such as cloth, washable and reusable cloth pads, menstrual cups, and period panties. The literature search revealed that there are limited studies related to the use of menstrual products and the impacts of these products on womenâs health and the environment. A rapid review of the literature identified factors responsible for choosing a particular type of menstrual product, the perceptions of women using the products, and their implications on health and the environment. The study concluded with the need to study the type of menstrual products preferred by women using appropriate variables, address the issues of disposal systems, provide adolescent girls with adequate infrastructure, provide access to affordable sanitary products and gender equity to manage their periods with dignity, and increasing awareness regarding sustainable/ reusable menstrual products, suggesting further investigation in menstrual hygiene management

PLASTIC BITUMEN MIX ROAD
Roads are the main system of transport which serves the house to house access to the people. The roads are given chief priority in the economy and the security of the country. The countries having no roads or fewer roads are still facing the problems.Dr. Ahmad Khan an owner of a plastic company first thought that his product is not only a boon to the world but a big curse also. He first carried out tests to practically use the plastic in the road construction. He developed a technology in which he successfully used the plastic bitumen mix in patching of pot holes in road
