Several research trials have evaluated the impact of ractopamine (RAC, Paylean r , Elanco Animal Health) on barrows and gilts of various genetic populations (GP). Overall, the desirable response of RAC to increase daily carcass lean gain, improve feed efficiency, and increase carcass lean percentage has been observed in GP of substantially different lean growth rates and carcass lean percentage...

abstract suspended sediment resulted from distributed soil erosions facilitates soil nutrients transportation and influences soil depletion. soil erosion plays a key role in loss of organic matter and therefore study of the relationship between organic matter and soil erosion processes and soil nutrient loss is very important. the present case study was conducted in kojour educational forest wa...

This paper presents a look at the concept of Lean Manufacturing as applied to the office environment. Lean Manufacturing, which is often referred to as Lean, is a philosophy of manufacturing process improvement through the elimination of waste.

This paper focuses on communication in personal area networks. A personal area networks (PAN) is characterized as an informal collection, or community, of connected small, lightweight, and resource-lean devices, or gadgets. Two basic concepts are visible in the development of PANs, the distributed and the centralized concept. The paper introduces a real-time communication protocol that is suita...

A control oriented dynamic model of the Lean NOx Trap (LNT) behavior has been developed in SIMULINK. The model simulates the trapping and purging phenomena and includes the important parameters which affect the LNT behavior. These include the trap temperature, trapping and purging duration, air fuel ratios and the mass flow rates of the exhaust gases. Engine dynamometer test data have been used...
