MAJOR FACTORS IN PLUTONIUM AND URANIUM FUEL FABRICATION COSTS.

Three major factors must be concomitantly assessed in order to extract relevant structural information from the surface of biological material at high resolution (2-3nm).Procedures based on chemical fixation and dehydration in graded solvent series seem inappropriate when aiming for TEM-like resolution. Cells inevitably shrink up to 30-70% of their initial volume during gehydration; important surface components e.g. glycoproteins may be lost. These problems may be circumvented by preparation techniques based on cryofixation. Freezedrying and freeze-substitution followed by critical point drying yields improved structural preservation in TEM. An appropriate preservation of dimensional integrity may be achieved by freeze-drying at - 85° C. The sample shrinks and may partially collapse as it is warmed to room temperature for subsequent SEM study. Observations at low temperatures are therefore a necessary prerequisite for high fidelity SEM. Compromises however have been unavoidable up until now. Aldehyde prefixation is frequently needed prior to freeze drying, rendering the sample resistant to treatment with distilled water.

Trainable Mentally Retarded

Twelve trainable mentally retarded children were given six weeks of instruction in the use of adjectives, polars, and locative prepositions. Specially prepared Language Master cards constituted the program. Posttests indicated that children in the older chronological age group earned significantly higher scores than those in the younger group. Children in the younger group made significant increases in scores, particularly in learning prepositions. A multisensory approach and active involvement in learning appeared to be major factors in achievement gains.

Sustainable Development (SD) is a rich, challenging and thought-provoking construct in social sciences. The main purpose of this paper was to identify and explore the role played by primary school teachers in building up the idea of sustainable development (SD) among students. This paper was intended to identify that how a teacher can successfully execute the concept of SD by influencing students’ minds at the primary level. Quantitative survey technique were utilized for data collection. All the primary school teachers of Lahore division comprised the population of the study. Through multistage sampling technique, 352 primary school teachers were selected as participants of the study. A self-developed SD questionnaire incorporating four major factors (teachers’ awareness, pedagogy, curricular and co-curricular activities) with Cronbach’s alpha value = .93 was used to measure the role of teachers in building the sustainability concept among students at primary level. The results indicated a significant mean score difference among SD scores of teachers, sector wise (private and public). Furthermore, the results also reconnoitered the significant difference (p=.04) between the mean scores of female and male teachers in building up the SD concept in students’ minds.

International Financial Regulation

We study the reform of financial regulation initiated by the Dodd—Frank Wall Street Reform and Consumer Protection Act of 2010. Major factors impeding Obama’s financial and economic policy are explored, including institutional difficulties, party warfare, lobbyism, and systemic inconsistencies of international financial regulation. We also examine challenges that are being faced by economic and political sciences due to the changes in financial regulation and also assess the level of radicality of the financial reform.
