The evolutionary mechanisms of energy efficiency have been addressed. One important question is to understand how the optimized usage of energy can be selected in an evolutionary process, especially when the immediate advantage of gathering efficient individuals in an energetic context is not clear. We propose a model of two competing metabolic strategies differing in their resource usage, an e...

scarcity of irrigation water and decreasing of water resources with suitable quality are the most important limiting factors in the crop production in the most of countries such as iran . therefore research for optimum usage of water and economy in consume water is important policies for growing of production and  the selection of cultivars with less necessity of water can help to matter.so, an...

Amaç: Bu çalışmada hastane içme, kullanma suyu ve sürüntü örnekleri mikrobiyolojik yönden incelenerek, risk oluşturup oluşturmadığı araştırıldı.Materyal Metot: Araştırmamızda 40 farklı içme başlıklarından alınan su ayrı olarak yöntemlerle incelendi. Su örneklerinin analizleri için membran filtrasyon yöntemi tek koloni düşürme ekim kullanıldı. Ayrıca kullanılan besiyerlerinde üreyen mikroorganiz...

With the continued growth and proliferation of Web services and Web based information systems, the volumes of user data have reached astronomical proportions. Analyzing such data using Web Usage Mining can help to determine the visiting interests or needs of the web user. As web log is incremental in nature, it becomes a crucial issue to predict exactly the ways how users browse websites. It is...

The functional layer is the pillar of the whole prognostics and health management system. Its effectiveness is the core of system task effectives. In this paper, we proposed a new bicluster mining algorithm: DoCluster, to effectively mine all biclusters with maximal variant usage rate and low usage rate in the discrete function-resource matrix. In order to improve the mining efficiency, DoClust...

Wet electrostatic precipitators (WESP) have been widely studied for collecting fine and ultrafine particles, such as diesel particulate matter (DPM), which deleterious effects on human health. Here, we report an experimental numerical simulation study a novel string-based two-stage WESP. Our new design incorporates grounded vertically aligned polymer strings, along thin films of water flow down...

In this work, a green, simple and highly efficient procedure for the synthesis of bis(indolyl)methanes is described. The condensation of indoles with carbonyl compounds catalyzed by citric acid in water affords bis(indolyl)methanes in high yields and relatively short reaction times. The advantages of this method are using of water as a low cost solvent and efficient recyclability of the catalyst.

crop’s water use efficiency (wue) is one of the major indices for the efficient use of water for crop production in agriculture. based on scientific literatures, the concept of wue has been defined in all crop management, farm/field, and water basin/irrigation network domains. plant in particular, plays an important role in the efficient use of water and enhancement of wue. plant resistance to ...

Software inspection helps to improve the quality of software products early in the development process. For design inspection recent research showed that usage-based reading of documents is more effective and efficient than traditional checklists. Usage-based reading guides actively the inspector with pre-sorted use cases, while traditional checklists let the inspector figure out how best to pr...

We have developed and deployed several web-based tutors for C++ programming concepts. We have been remotely collecting usage data from these tutors, and analyzing them for the benefit of the students, the teachers and ourselves. In this paper, we will describe the tutors, the types of data collected, and the types of analysis we perform on the data for the benefit of the various constituencies ...
