We study the demand function of a group of S members facing a global budget constraint. Any vector belonging to the budget set can be consumed within the group, with no restriction on the form of individual preferences, the nature of individual consumptions or the form of the decision process beyond efficiency. Moreover, only the group aggregate behavior, summarized by its demand function, is o...

consumer behavior is the most important issues in microeconomics. in neoclassical economics it is assumed that in order to reach the goals, human behavior is based on absolute rationality. while, simon criticizes the paradigm assumptions of neoclassic school and introduces the bounded rationality. since, because of uncertainty and lack of access to enough information, human faces with limited c...

Antigenic diversity among the bovine viral diarrhea virus (BVDV) cytopathic strains 87-2552 (field isolate) and NADL and Singer (prototype strains) was demonstrated with monoclonal antibodies (MAbs) in enzyme-linked immunosorbent, immunofluorescence, virus neutralization, and immunoprecipitation assays. Two MAbs against BVDV strain 87-2552, designated D11 and B7, strongly neutralized this field...

PURPOSE To develop an experimental model of acute inflammation, like aphthous ulcers, in oral cavity of rabbits, and also, to evaluate the results of the application of a polysaccharide spongy film of molasses from sugar cane as assist treatment in the healing process. METHODS Twenty adult rabbits weighting between 2.5 kg and 3.9 kg were divided into two groups: experimental and control infec...

Spinal chondroma is a rare benign tumor it accounts for 2.8% of bone tumours and 12% all tumours. 3.6% to 4% are located in the spine representing 10% chondromas. It can originate from vertebral bodies or posterior arch described patients between 5 78 years age [1]. We present clinical case 60 year old woman, who consulted dorso-thoracic pain around belt line was treated as gastroduodenal ulcer...

Primitive neuroectodermal tumours (PNET) are aggressive childhood malignancies and offer a significant challenge to treatment. A two years old female child presented with weakness both lower limbs. Preoperative MRI of the spine and paravertebral regionIso - hyper intense posterior placed extradural lesion, non contrast enhancing from D11-L2 levels with cord compression D9 to L3 laminectomy done...

A series of polyene–diphenylaniline based organic dyes (coded as D5, D7, D9 and D11) have been reported for the application in ionic liquid electrolyte based dye-sensitized solar cells. The effects of substitution of organic dyes on the photovoltaic performance have been investigated, which show addition of methoxy groups on the triphenylamine donor group increases short-circuit current, open-c...
