considering different fertility traits 411 cows from 73 farms used for economic analyses. from these, 202 lactating cows were selected for evaluating the fertility status. pre-tested data sheets were used to record the socioeconomic status of the farms including their assets, cost and return and productive and reproductive performance of the dairy cows. targets were set considering the situatio...

as the incidence of obesity increases, less invasive weight loss methods rather than bariatric surgery will be needed. this article reviews the advances in endoscopy, results, benefits and side effects of these techniques for treating obesity. the endoscopic options for weight loss could be broadly grouped under the following categories: restriction procedures, malabsorption procedures, and neu...

OBJECTIVE Obesity is related to a bias towards smaller immediate over larger delayed rewards. This bias is typically examined by studying single commodity discounting. However, weight loss often involves choices among multiple commodities. To our knowledge, no research has examined delay discounting of delayed weight loss compared with other commodities. METHODS We examined single commodity d...

In this study, a fractal, Y-shaped dual-mode resonator bandpass filter (BPF) with input-output cross-coupling is introduced. A parallel-coupling feed structure with a cross coupling has been used to generate two transmission zeroes (TZs) near the lower and upper cutoff frequency that can effectively improve the passband edge selectivity. Also, a fractal shaped based on conventional diamond and ...

This paper examines the interactions between high speed Ethernet switches and TCP in high bandwidth delay product networks. First, the behavior of a range of Ethernet switches when two long lived connections compete to the same output port is investigated. Then we study the impact of these switches behaviors on TCP protocols in long and fast networks (LFNs). Several conditions in which scheduli...

Rate allocation has become a demanding task in data networks as diversity in users and traffics proliferate. Most commonly used algorithm in end hosts is TCP. This is a loss based scheme therefore it exhibits oscillatory behavior which reduces network performance. Moreover, since the price for all sessions is based on the aggregate throughput, losses that are caused by TCP affect other sessions...

In Mobile Ad hoc Networks congestion control and prevention are demanding because of network node mobility dynamic topology. Congestion occurs primarily due to the large traffic volume in case data flow rate inflow is higher than packets on node. This alteration sending results routing delays low throughput. The Rate a significant concern streaming applications, especially wireless networks. TC...

Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...
