In this paper, a home network message specification for white goods based on power line communication is proposed. It is designed for white goods such as air conditioners, refrigerators, washing machines, etc. The proposed home network message specification is composed of a virtual device service and a devicespecific attribute. For practical implementation, an application software and two types...

As it is known, to provide fire protection for any type of surface vessel, external fire-fighting (EFF) systems have been commonly used decades as well in coastal regions. These types exist on several vessels such ships, tugboats, supply and naval vessels. Flow conditioners can be the EFF better performance by regulating flow inside fi-fi monitor. In present study, a (fi-fi) monitor was designe...

Three experiments were conducted to evaluate the effects of diet and monensin on performance, digestibility, and methane production in steers fed forage-based diets. In Exp. 1, 72 individually fed steers (300 ± 25 kg) were used in a randomized block design arranged as 2 separate 2 × 2 factorials with two common treatments, thus 6 diets were fed with 12 steers per treatment. Factors included hig...

Potential competition between native and domestic herbivores is a major consideration influencing the management and conservation of native herbivores in rangeland ecosystems. In grasslands of the North American Great Plains, black-tailed prairie dogs (Cynomys ludovicianus) are widely viewed as competitors with cattle but are also important for biodiversity conservation due to their role in cre...

The forage maturation hypothesis (FMH) proposes that ungulate migration is driven by selection for high forage quality. Because quality declines with plant maturation, but intake declines at low biomass, ungulates are predicted to select for intermediate forage biomass to maximize energy intake by following phenological gradients during the growing season. We tested the FMH in the Canadian Rock...

Understanding forage quality and the factors that affect its constituents will help improve livestock production by making decisions that optimize forage nutritive value and intake. This investigation was conducted in Zagros semi-arid rangeland center, Iran to determine forage quality of several grass and legume species. Samples were collected at early bloom, from 5 m long and 0.10 m wide strip...

An in situ study (Exp. 1) using 4 ruminally cannulated steers (343 ± 11 kg of BW) in a completely randomized design was used to compare ruminal degradation characteristics of low-quality cool-season (C3; Kentucky bluegrass straw; Poa pratensis; 6.3% CP; DM basis) and warm-season (C4; tallgrass prairie; 5.7% CP; DM basis) forage. Four ruminally cannulated steers (252 ± 8 kg of BW; Exp. 2) and 4 ...

In New Zealand, agriculture is predominantly based on pastoral grazing systems and animal excreta deposited on soil during grazing have been identified as a major source of nitrous oxide (N2O) emissions. Forage brassicas (Brassica spp.) have been increasingly used to improve lamb performance. Compared with conventional forage perennial ryegrass (Lolium perenne L.), a common forage in New Zealan...

The scroll compressor incorporates new construction concepts and is quite different from other types of compressor. This unique and simple compression mechanism has a number of advantages such as small size, light weight, high efficiency, long life, and quiet operation. The compliant mechanism is one of the key ways to improve the performance and reliability of scroll compressors. The concept o...
