Wireless Sensor Networks (WSNs) Akyildiz et al. (2002), Zhao & Guibas (2009) are formed of spatially distributed autonomous sensor nodes (motes). They are deployed in an environment where they can be used to monitor environmental conditions in collaboration, and communicate with each other through the wireless links. Several applications that are used in different areas have been outlined in th...
Collection is a core building block for many sensor network applications. In its simplest use, collection provides an unreliable, datagram routing service that deployments use to gather data [Werner-Allen et al. 2006; Mainwaring et al. 2002; Tolle et al. 2005]. A natural and efficient way to implement collection is by using a tree topology rooted at one or more collection points. Such trees are...
The Class A pan coefficient (Kp) has been used to convert pan evaporation (ECA) to grass-reference evapotranspiration (ETo), an important component in water management of irrigated crops. There are several methods to determine Kp values, using wind speed, relative humidity and fetch length and conditions. This paper analyses the following methods to estimate Kp values: Doorenbos & Pruitt (1977)...
to the number in which no significant effect was found has been criticised by a number of reviewers and is not the approach advocated by the Cochrane Collaboration. Although we have outlined above a number of points with which we take issue in the Evans and Allen review, we would like to conclude by stating that we do not think the differences between our position and theirs are as great as mig...
Cervical cancer is one of the most preventable cancers in the world and the 8th leading cause of cancer-related death in Korea (Miller et al., 1991; Whynes et al., 2007; Korea Ministry of Health & Welfare and Center, 2010). A regular Papanicolaou (Pap) test has been shown to be effective in detecting not only cancerous but also precancerous cells that can be removed (Paley, 2001; Lee et al., 20...
نشخوارکنندگان حیواناتی علفخوار هستند که می توانند به خوراک های با تخمیرپذیری سریع در شکمبه سازگار می شوند. اما این سازگاری همیشه با موفقیت همراه نیست. زیرا فرآیند تخمیر و تولید اسیدهای چرب فرار سریع تر و بیشتر از جذب یا خنثی شدن اسیدهای چرب فرار تولید شده است. لذا آنها در معرض بروز ناهنجاری های گوارشی از جمله اسیدوز هستند که می تواند علاوه بر مشکلات سلامتی و راحتی دام ها (plaizier et al., 2008)...

Over the last three decades, fluorescence spectroscopy has developed into a unique tool for probing biologically relevant systems. In particular, fluorescence correlation spectroscopy (FCS) is now a routine measurement enabling biologists access to reaction kinetics (Wu et al. 2006; Heyduk and Niedziela-Majka 2002; Allen and Thompson 2006) and sizes of biomolecular assemblies (Pitschke et al. 1...
