In the beef production system, 70-75% of the total dietary energy is used for maintenance (Ferrell and Jenkins 1984; NRC 1996; Montaldo-Bermudez et al. 1990). Thus, while only 5% of the total life cycle dietary energy consumption is used for protein deposition in beef cattle, swine and poultry are more efficient at 14 and 22%, respectively. The relatively large size, slow maturity and slow repr...

This paper presents sizing, energy management strategy, and cost analysis for a configuration consisting of solar photovoltaic (PV) panels, fuel cell (FC) storage system, and reverse osmosis (RO) desalination technology for combined power and fresh water production. In this system, PV is the main power supply source; fuel cell is a storage system accompanied by Hydrogen production and storage d...

Video production involves conceiving a story, shooting raw video footage, and editing the final piece. Editing involves manually cutting frames and frame sequences from the raw video and composing the sequences with special effects to render the production sequence of the original story concept. The introduction of digital video technology now greatly expedites this process and allows for novel...

This paper considers the impact of random machine breakdowns on the classical Economic Production Quantity (EPQ) model for a product subject to exponential decay and under a no-resumption (NR) inventory control policy. A product is manufactured in batches on a machine that is subject to random breakdowns in order to meet a constant demand over an infinite planning horizon. The product is assume...

In this paper, a production inventory model is considered for stochastic demand with the effect of inflation. Generally, every manufacturing system wants to produce perfect quality items. However, due to real-life problems (labor problems, machine breakdown, etc.), a certain percentage of products are of imperfect quality. The imperfect items are reworked at a cost. The lifetime of a defective ...

Organic farming systems rely on the management of biological cycles for the provision of nutrients, which are crucial to maximising the production from the system. Rotations based on the use of grass-legume leys are central to the concept of organic farming systems, because they have the potential to support both animal production, and a subsequent, exploitative, arable cropping phase. A major ...

While a great effort has concerned the development of fully integrated modular understanding systems, few researches have focused on the problem of unifying existing linguistic formalisms with cognitive processing models. The Situated Constructional Interpretation Model is one of these attempts. In this model, the notion of “construction” has been adapted in order to be able to mimic the behavi...

Heijunka is a key-element of the Toyota production system. It is used to level the release of production kanbans in order to achieve an even production program over all possible types of products thus reducing or eliminating the bullwhip effect. In this paper the dependencies between the parameters of the levelling process and the requirements in finished goods stocks are derived, resulting in ...

monascus purpureus is a fungus that had been cultured on the rice in eastern asian countries since thousands years ago and used as a food for long years. the fungus produces very valuable metabolites with polyketide structure. the most important metabolite is monacolin k, lovastatin or competitive inhibitor of 3-hydroxy-3-methylglutaryl-coenzyme a reductase (an affective enzyme in cholesterol s...

epidermal growth factor (egf), a growth factor involved in cell growth and differentiation, is a small polypeptide with molecular weight of approximately 6 kda known to be present in a number of different mammalian species. experimental studies in animals and humans have demonstrated that the topical application of egf accelerates the rate of epidermal regeneration of partial-thickness wounds a...
