In the spring and summer of 2001, 47 fathers, 48 mothers and 117 children of Iowa farm and non-farm households were recruited to participate in a study investigating take-home pesticide exposure. On two occasions approximately 1 month apart, urine samples from each participant and dust samples from various rooms were collected from each household and were analyzed for atrazine, metolachlor, gly...

In this paper we analytically derive the sojourn time of a user accessing an online IPTV recording service. Basically, the system consists of a server (or server farm) and the bandwidth at which a user can download recorded files depends on the number of other concurrently downloading users. In particular, we consider both cases, one in which the user’s download speed is limited by his own acce...

In order obtain suitable and effective farm machinery performance besides higher crop yield, on time farm machinery field operations are essential. Farm tractors are important machines that used for soil tillage, crop planting and protection. It is even used for harvesting crops in some areas. Thus, any failure in farm tractors influences the series of field operations. Farm managers are usuall...

This paper describes the Brimstone Farm dataset used for the comparison of pesticide leaching model performance. The tasks set to the modellers are then described. The soil of the site is heavy clay, in which cracks have a major effect on the hydrology. Data are presented for the leaching of isoproturon and mecoprop from two contrasting plots. Contrasting soil moisture states, resulting from di...

This study attempt to reveal the opportunities for increasing peasant farmers income through snail production in Ghana. The paper stressed that snail production is a crucial means of increasing peasant farmers income, protein supply and utilization of farm scraps in Ghana. This is because, from putting up structure, obtaining snails and feed, caring to harvesting, snail production is very cheap...

We present the implementation and experiments of a Web switch that transforms a cluster-based Web system (Web cluster) with best-effort management policies into a system that gives guaranteed performance to different classes of users and applications.

The extent to which farm families engage in off-farm employment activities is a topic of central importance to understanding the financial well-being of farm households. The degree of financial stress experienced by U.S. farm families is always a concern to policy makers. Yet, policy considerations often ignore the substantial involvement of most farm households in nonfarm labor markets. It has...

BACKGROUND Activation of peroxisome proliferator activated receptor gamma (PPAR γ) in the alveolar macrophages (AM) by selective synthetic PPAR γ ligands, improves the ability of the cells to resolve inflammation. In birds, respiratory macrophages are known as free avian respiratory macrophages (FARM) and show distinct functional differences from AM. The effects of treating FARM with PPAR γ lig...

In this study, we employ a dynamic treatment effect approach to analyze heterogeneity in returns farmers at different stages of adoption newly introduced inoculant technology, using recent survey data 600 soybean from northern Ghana. Although differ their new technologies, many empirical studies often fail account for heterogeneity. The results reveal that who are advanced appear to, on average...
