The number of cloud users has been growing everyday and it seems that scheduling of virtual machines in the cloud becomes an important problem to analyze. Lively consolidation of Virtual Machines is an efficient way to get better use of resources and power efficiency in Cloud data centers. Identifying when it is best to move VMs from a congested host is an aspect of Lively VM consolidation that directly influences the resource consumption and Quality of Service (QoS) delivered by the system. Server overloads is the basis of resource insufficiency and spoils the performance of applications which leads to affect the QoS. This paper focus on the importance of the detection of server overload and compares the various scheduling algorithms currently used for scheduling virtual machines and also proposes the design methodology of a new algorithm that helps to improve the resource utilization and at the same time energy efficiency. © 2014 IEEE.

Ultrasound is a reliable technique for the early detection and diagnosis of breast cancer. Breast cancer is the second leading cancer responsible for the highest rate of mortality among women around the world. Earliest detection and diagnosis is proved to be the only way of curbing the breast cancer and to reduce the mortality rate. The automated Computer Aided Diagnosis systems are helpful for the physicians in diagnosing the presence of breast lesions and classifying them into benign and malignant. Methods proposed in diverse articles for preprocessing, segmentation, feature extraction and classification of breast lesions are reviewed and presented in this paper. Algorithms and databases employed at every stage of automated processing and evaluation parameters along with the results are also investigated. © 2014 American Scientific Publishers All rights reserved.

COVENTRY, 20-Feb-2017 — /EuropaWire/ — The University of Warwick, as a part of the National Collaborative Outreach Programme (NCOP) is working with nine schools and colleges across seven wards in Warwickshire to increase participation in higher education. Paul Blagburn, Head of Widening Participation at the University of Warwick said: “The University of Warwick is delighted to lead this new collaborative initiative designed to provide a real opportunity for young people and their families in the targeted Warwickshire wards to realise their potential and aspire to go to higher education. The programme will complement the University’s existing outreach work and will employ new staff to work directly with learners in the schools and colleges”. Launched last week, the scheme will see a total of 260 higher education providers in England, collaborating with schools, colleges and other organisations to help more disadvantaged young people into higher education. These providers are organised into 29 regional consortia which will ensure all 997 of the local wards identified by HEFCE will be covered. The University of Warwick’s Think Higher project aims to develop close partnerships with the schools in the local wards. Through these partnerships, the university will develop a better understanding of the barriers faced by young people in these particular areas, with local context being at the heart of the project. The Think Higher project will develop outreach activity that is responsive to the needs of the local area and can support schools with their work to ensure young people in Warwickshire have access to the higher education opportunities on offer. Uly Lyons, Principal of King Edward VI College in Nuneaton said: “King Edward VI College is very excited to be taking a leading role in the NCOP. We have a long and proud history of helping the young people of Nuneaton progress to university, raising their aspirations and life chances as a result. We are aware that within the current economic context the prospect of university may seem daunting to young people locally and their families. I’m confident the project will have a significant impact on ensuring that more young people in the area do fulfil their potential and progress and progress to university. In particular I’m excited about the joined up approach we are taking, ensuring that schools, colleges and universities are all working together in a collaborative way to help students reach their potential and improve the quality of life for themselves, their families and the local area in general.” HEFCE aims to increase participation in higher education across England, the National Collaborative Outreach Programme (NCOP). With funding of £60 million per year, the programme will drive a step change in the progression into higher education of young people from disadvantaged backgrounds, including members of ethnic minority groups and young men. A large-scale evaluation programme will measure the impact of the programme from the start, at local and national level, including national data analysis, longitudinal tracking, qualitative research and randomised control trials. The aim will be to build a powerful evidence base to ensure that investment is concentrated in activity that is shown to be the most effective.

Drought indices (DI) are an useful tool for assessing different sectarian droughts. Standardized Precipitation Index (SPI) has been used worldwide to assess/monitor the onset, active phase, cessation and severity of drought. Normalized Difference Vegetation Index (NDVI) provides a comprehensive vegetation dynamics, which directly linked with rainfall received in a particular region. Indo-Gangetic Region (IGR), providing employment and livelihood to tens of millions of rural families directly or indirectly and rice (Oryza sativa L.)-wheat (Triticum aestivum L.) (RW) system of the Indo-Gangetic Plains (IGP) contributes 80% of the total cereal production and is critical to food security of the region. This study tries to verify the applicability of water-vegetative indices viz., SPI, Rainfall Index (RI) and NDVI for drought assessment of rice-wheat system productivity over IGR-India. The relationship between monsoon rainfall and NDVI shows that at around 1100. mm rainfall, the NDVI reached saturation point and no further significant increase in NDVI with increase of rainfall is noticed. Even though, there was a positive correlation of seasonal monsoon rainfall and average NDVI, conflicting results are noticed between monthly distribution of rainfall and monthly anomaly of NDVI over IGR States. It is noticed that June dif NDVI (actual NDVI-mean NDVI) contributes more to rice productivity followed by July. However, the combined effect of June, July and August, explains 15% of the variation of Kharif Rice Productivity Index (KRPI). As far as wheat is concerned, statistically significant relation was found between Wheat Productivity Index (WPI) and anomaly NDVI during December-March. This explains 35% of the variability in WPI. © 2011 Elsevier B.V.

Galvanic coupling technique is capable of producing coatings of desired thickness. Good quality coatings can be produced at low temperature. Galvanic coupling of mild steel (MS) with the other cathode materials such as titanium (Ti), copper (Cu), brass (BR), nickel (Ni), and stainless steel (SS) accelerates iron dissolution, enables quicker consumption of free phosphoric acid and facilitates an earlier attainment of point of incipient precipitation, resulting in a higher amount of coating formation. In the present investigation, potentiodynamic polarization and electrochemical impedance spectra on MS substrates phosphated using galvanic coupling are studied. This study reveals that MS substrates phosphated under galvanically coupled condition possess better corrosion resistance than the substrates phosphated under uncoupled condition. © ACA and OCCA 2011.

Scientists at the Donald Danforth Plant Science Center have teamed up with researchers at Willamette University, a liberal arts college in Salem Oregon, to develop genetic tools that could save the Joshua tree from extinction. Together with scientists from The University of Georgia and the University of British Columbia, and with the support of several Mojave Desert conservation organizations, researchers are inviting members of the public to help get the project off the ground by making donations at the crowdfunding site Experiment.com. In the past two weeks, more than 100 backers have donated more than $4,000 to The Joshua Tree Genome Project. The project aims to raise $8,500 by March 24th. Joshua trees are the iconic species of the Mojave Desert, the hottest and driest desert region of North America. This keystone species provides food and habitat for many other species, and numerous State and National Parks are dedicated to their conservation. However, emerging research suggests that Joshua trees are disappearing across much of the Mojave Desert, perhaps because of ongoing global warming. Some scientists predict that the trees may go extinct within the next 100 years. The project, one of 17 projects that are participating in Experiment.com's Liberal Arts College Pilot Program. The pilot program at Experiment.com aims to bring the power of crowdfunding to research labs at small undergraduate institutions. To help support colleges participating in the program, Experiment will contribute an extra $2,000 to the project that receives the most donors by March 16th. "Understanding the genome will help us make conservation plans that allow Joshua tree to adapt to changing climates and environments," said project scientist Christopher Irwin Smith, a biologist at Willamette University. "The genome could also answer many important questions about the evolutionary history of this iconic desert species." "The data will provide our first detailed look into the Joshua tree genome," said Michael McKain, an evolutionary biologist working on the project and a post-doctoral associate at the Donald Danforth Plant Science Center. "It will allow us to untangle Joshua trees' diversity at the most basic level, and identify how major evolutionary events contributed to its unique form." Ensuring that Joshua trees will flourish into the future means preserving the plants themselves and the genetic variation that will allow them to evolve in response to environmental changes. "Sequencing the Joshua tree genome is the first step to revealing the genetic basis of climate adaptations," said Jeremy Yoder, a post-doctoral fellow studying evolutionary biology at the University of British Columbia. "And from there we can identify gene variants that may allow Joshua trees to survive rising global temperatures."

In the present investigation, crystals of Bismuth Iodate[Bi(IO3)3], Bismuth Iodide[BiI3] and Bismuth- Tri Sulphide [Bi2S3] were grown by a simple gel technique using single diffusion method. The optimum growth conditions were established by varying various parameters such as pH of gel solution, gel concentration, gel setting time, concentration of reactant etc. Gel was prepared by mixing sodium meta silicate (Na2SiO35H2O), glacial acetic acid (CH3COOH) and supernant bismuth chloride (BiCl3) at pH value 4.4 and transferred in glass tube of diameter 2.5 cm and 25 cm in length. The mouth of test tube was covered by cotton plug and kept it for the setting. After setting the gel, it was left for aging. After 13 days duration the second supernant K(IO3), KI3 and H2S water gas solution was poured over the set gel by using pipette then it was kept undisturbed. After 72 hours of pouring the second supernatant, the small nucleation growth was observed at below the interface of gel. The good quality crystals of [Bi(IO3)3], [BiI3] and [Bi2S3] were grown. These grown crystals were characterized by XRD, FTIR, Chemical Analysis and Electrical Conductivity. © 2012 Sumy State University.
