Server farms are popular architectures for computing infrastructures such as supercomputing centers, data centers and web server farms. As server farms become larger and their workloads more complex, designing efficient policies for managing the resources in server farms via trial-and-error becomes intractable. It is hard to predict the exact effect of various parameters on performance. Stochas...

Restoration and maintenance of habitat diversity have been suggested as conservation priorities in farmed landscapes, but how this should be achieved and at what scale are unclear. This study makes a novel comparison of the effectiveness of three wildlife-friendly farming schemes for supporting local habitat diversity and species richness on 12 farms in England.The schemes were: (i) Conservatio...

Ethiopia has the largest livestock population in Africa but the contribution of this resource to the economy is limited and yet the country is in poverty. Dairy development has a big role for the contribution of income generation and employment. Demand for dairy products seems to exceed supply in the country in general and the study area in particular. Hence, the situation of dairy production a...


 Abstract:There is a growing need of sustainable building development all over the world. It aims to decrease adverse effects environment due urbanization and escalating population growth. Since construction considered as one main concerns, priority was given mitigate negative impact environment. Therefore, incorporating elements techniques buildings regain land loss activities in cities ...

Vertical farms have expanded rapidly in urban areas to support food system resilience. However, many of these systems source a substantial share their material and energy requirements outside environments. As produce significant shares residual streams, there is considerable potential explore the utilization streams for agriculture addition possibility employing underutilized spaces residential...

Dermanyssus gallinae (Mesostigmata: Dermanyssidae), a mite of poultry, represents the most important ecotoparasite of egg-laying poultry in several countries. We estimated the prevalence of D. gallinae infestation in 38 industrial poultry farms (28 egg-laying and 10 reproductive hen farms) in the governorate of Nabeul (North-East Tunisia). Traps were placed in two locations of each farm during ...

This paper presents the results of an analysis that predicts the scale efficiency of individual farms and analyses the differences in scale efficiency over time and between farms. Representative farm account data for 1985–2006 are used, and the study applies stochastic frontier analysis using an input distance–function approach. The results show that pig farms have improved their input scale ef...

The laudable intentions of science to research the effects of different variables on the ability to predict the time death interval accurately have become embroiled onmultiple complex fronts. The colloquial and persistent use of the term ‘body farm’, the rhetoric that surrounds media reporting, and the sometimes distasteful display of the subjects, detract significantly from any scientific meri...

Bioacoustic localization of bird vocalizations provides unattended observations of the location of calling individuals in many field applications. While this technique has been successful in monitoring terrestrial distributions of calling birds, no published study has applied these methods to migrating birds in flight. The value of nocturnal flight call recordings can increase with the addition...

The Peruvian altiplano is a marginal agricultural region with limited infrastructure, climate constraints, and high levels of poverty. Data were collected from 265 farms in four different agricultural regions, and data from three of those regions are analyzed here. Regressions were run with soil nutrient loss, soil depth loss, and yield loss over the past 20 years, as perceived by farmers. Loca...
