Introduction During the 1980s, the beef slaughtering industry became increasingly concentrated. In 1980 the four largest packers slaughtered 36% of fed cattle nationally and marketed 53% of boxed beef. By 1989 the four largest firms slaughtered approximately 69% of the fed cattle and marketed more than 80% of the boxed beef (Purcell 1990a; Lambert 1990). Concentration is even higher in some reg...

An introductory programming course such as CS1 is one of the most essential courses in terms that successive computer science (CS) courses heavily depend on students’ attainment level of CS1. In this study, we show our experience of our CS1 course to conform with diversified students’ interest. We introduce (1) “virtual small group classes”(VSCs) which are practical laboratory programming work ...

This dissertation aims at combining the benefits and to remedy the flaws of the two popular frameworks in statistical machine translation, namely Phrasebased MT and N-gram-based MT. Phrase-based MT advanced the state-of-the art towards translating phrases3 than words. By memorizing phrases, phrasal MT, is able to learn local reorderings, and handling of other local dependencies such as insertio...

Polyomavirus middle tumor antigen (MT) transforms a large number of cell types by binding to and modulating the activities of cellular proteins. Previous genetic analysis defined in MT an independent motif, NPTY (Asn-Pro-Thr-Tyr), required for transformation. This report demonstrates that NPTY is required for interaction between MT and SHC protein, a Src homology 2 (SH2)-containing protooncogen...

the main object of this study was to evaluate the effect of tillage and crop residues management of barley (hordeum vulgare l.) on quantification and qualification yield of corn (zea mays l.). treatments were laid out in complete randomized block design with seven treatments and three replications and include (1) fire of straw and stubble, plow, disc and furrower (2) gathering and transfer of s...

Saccades should cause us to see a blur as the eyes sweep across a visual scene. Specific brain mechanisms prevent this by producing suppression during saccades. Neuronal correlates of such suppression were first established in the visual superficial layers of the superior colliculus (SC) and subsequently have been observed in cortical visual areas, including the middle temporal visual area (MT)...

We are studying a hydraulic system design and vehicle dynamic modeling for a development of tire roller system, because those are very important in analysis of tire roller. Generally, tire roller is one of the useful machines in a road construction field and it technically applied for many other construction fields. Also, we conceptualize of new hydraulic and traction system, and define about t...

Biphasic positive airway pressure (BiPAP) is a ventilatory mode in which two pressure levels (higher (Phigh) and lower (Plow)) acting as continuous positive airway pressure (CPAP) alternate at preset time intervals. BiPAP combines pressure-controlled ventilation with unrestricted spontaneous breathing. BiPAP has not yet been evaluated in patients with chronic obstructive pulmonary disease (COPD...

Tillage is the base operation in agriculture and its energy represents a considerable portion of the energy utilized in crop production. To measure the implement force requirements, are used dynamometers that are pull or three-point hitch types. In this research, an 82 kW research tractor equipped with an instrumentation system was used to determine the draft force inputs for four common tillag...
