abstractgiven the importance of the notion of efficiency in the country's economic growth, measuring the efficiency and the technology gap for various industries in order to achieve the best possible resource assignment, following the declared policy goals, is of particular importance for those countries, such as iran, which are now at the early stages of the industrialization process. hen...

50S ribosomal subunits were reacted with bis-(2-chloroethyl)methylamine, 2-iminothiolane or methyl p-azidophenyl acetimidate, and RNA-protein cross-link sites on the RNA were localised using our published procedures. The degree of precision with which these sites could be determined was variable, depending on the particular protein or RNA region concerned. The following positions in the 23S RNA...

Growth and development of pig fetuses is dependent on the coordinated expression of multiple genes. Between 21 and 45 days of gestation, fetuses experience increasing growth rates that can result in uterine crowding and increased mortality. We used differential display reverse transcription-PCR (DDRT-PCR) to identify differentially expressed genes in pig fetuses at 21, 35, and 45 days of gestat...

In this paper we explain the apparent ”diversification discount” of conglomerates without assuming inefficient-cross subsidisation through internal capital markets. Instead we assume that an internal capital market efficiently redistributes scare resources across a conglomerate’s divisions between successive production periods. The need for redistribution arises from the fact that resources may...

Background: Occupational diseases are very prevalent in the world, especially in developing countries. Occupational dermatoses are responsible for most of these cases. However, epidemiological studies are rare in Brazil. oBjectives: To verify the panorama of occupational skin diseases in Brazil describing frequencies of work-related dermatoses and their sociodemographic and occupational pattern...

IN MULTI-ESTABLISHMENT FIRMS: THE LOCUS OF I.T. SYSTEMS PURCHASING AUTHORITY By Kristina Steffenson McElheran* thSeptember 17, 2009 Abstract This paper presents a large-scale empirical study of the allocation of authority in multi-establishment firms. Specifically, it investigates how tradeoffs between adaptation and coordination may influence the allocation of decision rights over information ...

The aim of the present study was to evaluate for the first time the in vitro cytotoxic activity of fractions and isolated flavonols from Salsola oppositifolia Desf. (Amaranthaceae). The n-hexane fraction demonstrated an effective cytotoxic activity on the large lung carcinoma and amelanotic melanoma cell lines with IC50 values of 19.1 microg/ml and 24.4 microg/ml, respectively. Also the dichlor...

In this paper we address the question of collusion in mechanisms under asymmetric information by assuming that one of the colluding parties offers a side contract to the other one. We develop a methodology to analyze collusion as an informed principal problem. We show that if collusion occurs after the agents accept or reject the principal’s offer, the dominant-strategy implementation of the op...

YsxC is a small GTPase of Bacillus subtilis with essential but still unknown function, although recent works have suggested that it might be involved in ribosome biogenesis. Here, purified YsxC overexpressed in Escherichia coli was found to be partly associated with high-molecular-weight material, most likely rRNA, and thus eluted from gel filtration as a large complex. In addition, purificatio...
