Objectives: Volunteering has great economic and social benefits, but it is neglected due to the nature of the work. This study aimed to assess the monetary aspect of the voluntary activities in the National Plan of Safety and Health of Nowruz Passengers and analyze the cost of the implementation of this plan, regarding youth volunteers. Methods: In this descriptive-analytical study, 1574 volun...
Due to high latency of the Internet, it becomes a challenge to access large and widely distributed data quickly and efficiently on data grids. Replication is a process to address this issue, by storing data in different locations to reduce access latency and improve data locality. However, because of the limited storage capacity, a good replica replacement algorithm is needed to improve the eff...
25 Even though several sow replacement models have been published, integrating 26 information about the health status of sows has not yet been handled satisfactorily. This 27 paper presents a framework for integrating a Weak Sow Index (WSI) into an existing 28 sow replacement model. The WSI, which is developed as part of this study, quantifies 29 various clinical signs into one numerical value ...
The purpose of this study was to survey the effect of dietary fish oil replacement with different levels of soybean lecithin on growth performance and digestive enzymes activity of Persian sturgeon. Three hundred and sixty fish with average weight of 85 ± 0.09 g were treated with 6 experimental diets and three replicates, containing 0, 2, 4, 6, 8 and 10 percent soybean lecithin for 10 weeks. Ba...
BACKGROUND Millions of peripheral intravenous catheters are used worldwide. The current guidelines recommend routine catheter replacement every 72-96 h. This practice requires increasing healthcare resource use. The clinically indicated catheter replacement strategy is proposed as an alternative. OBJECTIVES To assess the cost effectiveness of clinically indicated versus routine replacement of...
A new replacement analysis methodology is developed to determine system-level component replacement schedules for radial electricity distribution configurations composed of sets of heterogeneous assets. The proposed model is an iterative combined dynamic programming and integer programming approach to obtain cost-efficient system-level component replacement schedules with the objective of minim...
To study the effect of castration and testosterone replacement on the testosterone level of the New Zealand rabbit, 16 apparently healthy adult male rabbits were used. The animals were divided into four groups with each group having four rabbits. The first group served as the control group. The rabbits in the second group were unilaterally castrated, while those in the third group were bilatera...
It has long been our view that improvements in gilt development programs can lead to major improvements in breeding herd efficiency. Whether gilts are reared in ‘in-house’ gilt multiplication systems, or supplied by a breeding company, available data suggest that the proper selection and management of replacement gilts has an impact on lifetime non-productive days (NPD). As discussed later, we ...
Stream data mining is the process of excerpting knowledge structure from large, continuous data. For stream data, various techniques are proposed for preparing the data for data mining task. In recent years stream data have become a growing area for the researcher, but there are many issues occurring in classifying these data due to erroneous and noisy data. Change of trend in the data periodic...
