Four trials, each with a randomized complete block design, were conducted with 8,647 beef steers (initial BW = 346 +/- 29.6 kg) in 3 different locations in the United States to evaluate the effects of zilpaterol hydrochloride (ZH) on performance and carcass characteristics of feedlot cattle. Treatments consisted of feeding ZH (8.33 mg/kg of dietary DM) for 0, 20, 30, or 40 d, at the end of the ...

Rain attenuation is a major shortcoming of microwave transmission. J.S Ojo1, 2, M.O Ajewole1, S.K Sarkar2. An improved approach of predicting rain attenuation cumulative. rain attenuation formula Approach for determining the values of rain attenuation at different.Attenuation due to rain is an important constraint in the designing of the microwave. The paper presents a new prediction model of r...

This letter proposes a simple method of transferring rain structures of a given exemplar image (rain image) into a target image (non‐rain image). Given the exemplar rain image and its corresponding masked rain image, rain patches including real‐life rain structures are extracted randomly, and then residual rain patches are obtained by subtracting those rain patches from their mean patches. Next...

Global warming will continue, and the Arctic is expected to warm at twice the global average rate (Intergovernmental Panel on Climate Change 2007). The most pronounced changes will occur during winter with increased precipitation, more precipitation falling as rain, and a shorter snow period (Intergovernmental Panel on Climate Change 2007; Roderfeld et al. 2008). These changes will have far-rea...

In order to fully understand what a given boiler needs for treatment, a basic study of its supply water must be done first. Three types of impurities exist in all supplies and can cause a wide range of problems in boilers and kilns. These impurities are suspended solids, dissolved solids, and dissolved gasses. Water picks up the impurities from the ground it contacts and the air through which i...

Natural disasters threaten the humans from time immemorial. They are caused both by the processes in the Earth core and Earth surface, or in the atmosphere, and by the processes in the vicinity of the Planet. From the current knowledge it follows that in human system various phenomena take place in the development process that are the expression of its development or of the development of syste...

Automation for the identification of plants, based on imaging sensors, in agricultural crops represents an important challenge. In maize fields, site-specific treatments, with chemical products or mechanical manipulations, can be applied for weeds elimination. This requires the identification of weeds and crop plants. Sometimes these plants appear impregnated by materials coming from the soil (...

Wireless sensor network technology has the potential to reveal finegrained, dynamic changes in monitored variables of an outdoor landscape. But there are significant problems to be overcome in order to realise this vision in working systems. This paper describes the design and implementation of a reactive, event driven network for environmental monitoring of soil moisture and evaluates its effe...

To curtail data centers’ huge cooling power consumption and water demand (for cooling), air-side economizer has been increasingly adopted to cool down servers. Recently, another sustainability practice, rainwater harvesting, has also seen a growing adoption in data centers, potentially leading to water self-sufficiency without connecting to water utilities to supply cooling water. Nonetheless, ...

Satellites play a major role in the determination of the rainfall at sea. Researchers at Southampton Oceanography Centre (SOC) have been involved in two projects addressing this task. First they have been instrumental in developing techniques to retrieve rain rate information from the 10+ years of dual-frequency altimeter data. The TOPEX radar measures rainfall via the attenuation it causes, pr...
