in the present study an attempt has been made to use a non-parametric method data envelopment analysis (dea) for assessing source-wise and operation-wise the technical efficiency (te) and return-to-scale (rts) for paddy production in four zones of the state of punjab, india. the results were then compared to corresponding ones already obtained from a parametric method (cobb-douglas production f...

The production-transportation problem (PTP) is a generalization of the transportation problem. In PTP, we decide not only the level of shipment from each source to each sink but also the level of supply at each source. A concave production cost function is associated with the assignment of supplies to sources. Thus the objective function of PTP is the sum of the linear transportation costs and ...

the objective of this study was to evaluate the effects of sources of four starch on milk production and composition, nutrients digestibility and blood metabolites of lactating holstein cows. eight multiparous holstein cows (683±31 kg of body weight; 83±9 dim) were used in a replicated 4×4 latin square design with 21-d periods. the exprimental diets contained wheat, barley, corn, or potato as t...

pierre-gerlier forest and his colleagues make a strong argument for the need to expand policy capacity among healthcare actors. in this commentary, i develop an additional argument in support of forest et al view. forest et al rightly point to the need to have embedded policy experts to successfully translate healthcare reform policy into healthcare change. translation of externally generated i...

Women are underrepresented in open source projects, causing them to lose career and skill-development opportunities. This article highlights the challenges that women face being a part of projects lists set strategies communities can implement mitigate these issues.

The increasing need for food production in subtropical regions likely translates to a need for additional plant nutrients. As a consequence, knowledge of world fertilizer nutrient reserves is of particular relevance to sustainable agriculture in the subtropics. The stewardship responsibilities of agriculture include the wise use of the raw materials from which commercial fertilizers are produce...

This is an outline of the knowledge we need in order to include the voice source in an advanced model of speech production with applications to text-to-speech rules. Recent results from studies of the Swedish language provide information of source properties and source-vocal tract interaction as a function of the segmental and prosodic frame within an utterance and with reference to aerodynamic...

Ultimately in any natural language production system the largest amount of human effort will go into the construction of the dictionary: the data base that associates objects and relations in the program's domain with the words and phrases that could be used to describe them. This paper describes a technique for basing the dictionary directly on the semantic abstraction network used for the dom...

Lipases have many applications in biotechnology, thanks to their ability of acylglycerides hydrolysis. They alsp possess the unique feature of acting at the lipid-water interface, which distinguishes them from esterases. Commercially useful lipases are produced by microorganisms with the extracellular lipase being produced by many bacteria including Pseudomonas. The greatest production of lipas...
