The status of Science and Technology in KUWAIT has been analysed in order to assess the extent of the application of Science and Technology needed for the Country's development. The design and implementation of a Science and Technology Policy has been examined to identify the appropriate technology necessary to improve KUWAIT's socio-economic-industrial structures. Following a general and critical review of the role of Science and Technology in the developing countries, the author has reviewed the past and contemporary employment of Science and Technology for development.of various sectors and the existence, if any, of any form (explicit, implicit, or both) of a Science and Technology Policy in KUWAIT. The thesis is structured to evaluate almost all of the sectors in KUWAIT which utilise Science and/or Technology, the effectiveness of such practices, their policymaking process, the channels by which policies were transformed into sources of influence through Governmental action and the impact that various policy instruments at the disposal of the the Government had on the development of S & T capabilities. The author has studied the implications of the absence of a Science and Technology Policy in Kuwait by examining some specific case studies, eg, the absence of a Technology Assessment Process and the negative impacts resulting from this; the ad-hoc allocation of the research and development budget instead of its being based on a percentage of GNP; the limitations imposed on the development of indigenous contracting companies and consultancy and engineering design offices; the impacts of the absence of Technology Transfer Centre, and so forth. As a consequence of the implications of the above studies, together with the negative results from the absence of an explicit Science and Technology Policy, eg, research and development activities do not relate to the national development plans, the author suggests that a Science and Technology Policy-Making Body should be established to formulate, develop, monitor and correlate the Science and Technology Activities in KUWAIT.

This chapter summarises some of the learning from a material practice that sits in a sisterly manner next to architecture. Drawing on feminist writing and the experiences of women in professional life more generally, the chapter will examine how mainstream understanding of time and technology limit the engagement of those people in society who do not fit given norms. The chapter argues that when we examine such concepts in more detail and expand them to reflect diverse experiences those very same concepts offer new potentials and innovative openings for the progression of disciplines such as architecture.

Nascida para permitir que seus criadores possam atender suas próprias necessidades, a técnica científica sempre desempenhou papel significativo na civilização humana. Este é o contexto em que podemos vislumbrar o advento da tecnociência moderna, que tem contribuído significativamente para o incremento do controle humano sobre a natureza. Este estudo tem por objetivo analisar, sob o enfoque da bioética, reflexões sobre como a filosofia da ciência entende a neutralidade da ciência e sua convergência com a racionalidade epistêmica, bem como relacionar essas reflexões ao processo de tomada de decisões na administração da tecnociência. O estudo levantou dúvidas sobre a capacidade do conhecimento tecnocientífico para legitimar e justificar as decisões no âmbito dos sistemas de ciência e tecnologia nacionais, sinalizando assim a necessidade de promover ligação entre a auto-regulação tecnocientífico e hetero-regulação bioética. ______________________________________________________________________________ ABSTRACT

Medical research has greatly beneited from molecular biology and increasingly relies on tools from the “omics” disciplines (mainly genomics, transcriptomics, proteomics and metabolomics). The availability of biological samples preserved with high quality standards is a sine qua non condition for such studies and their repositories are referred to as biobanks. Biobanks support the transportation, storage, preservation, and initial pathological and analytical examinations of biospecimens, as well as the protection of relevant information and the comparison of clinical and laboratory findings. A biobank facility is one of the most valuable tools the academic medicine organizations can offer to their researchers to improve the competitiveness of their current and future medical research. it acts as an essential bridge and an effective catalyst for research synergies between basic and clinical sciences, and it can be potentiated with efforts to raise funds for acquiring and maintaining cutting-edge analytical infrastructure to better serve its clinical, pharmaceutical and biotech clients.

This review was requested by the Department of Disabilities and Special Needs for an independent review of allegations of abuse, neglect, and exploitation at SC Mentor, a private provider of residential services for DDSN consumers. An analysis of incidents did not indicate systemic abuse towards consumers inasmuch as the majority of the ANE reporting system contained allegations more akin to staff/facility performance issues and the vast majority of all allegations were unsustained by independent investigations. In the future, DDSN should expand the level of detail in its ANE reporting, which currently only reports total allegations and sustained criminal incidents.

Fish assemblages in seagrass and unvegetated habitats located in shallow intertidal creeks within the saltmarsh area of the Ria Formosa coastal lagoon were sampled with a Riley push net at 3 sites on a monthly basis over a 1 yr period. The objective was to test if both habitats support similar fish assemblages in terms of abundance, diversity, assemblage structure, and size distribution, and to investigate how site and season affect the assemblages. Fish assemblages associated with these habitats were significantly different in terms of diversity, abundance, and assemblage structure. Seagrass supported a larger number of species and greater diversity, while unvegetated habitat supported greater fish numbers but only of a few species. The habitats were dominated by different groups of resident species that were responsible for major differences in fish assemblage structure between habitats. Pomatoschistus microps and young-of-the-year (YOY) Atherina presbyter dominated the unvegetated habitat, while seagrass was dominated by a diverse group of species, in particular syngnathids and small labrids, revealing different habitat preferences. Site and season were determinant factors conditioning the role of habitat in structuring fish assemblages. Distance between habitats, site elevation, and the amount of marsh drained affected fish assemblages in both habitats. Seasonal fluctuations in the presence and abundance of YOY from marine migrant and resident species were responsible for comparable changes in fish assemblage structure in both habitats. Both habitats provide a distinctive nursery area for different species, while common species reveal ontogenic distributional changes between habitats, where smaller fish appear first in unvegetated creeks.

Torrefaction experiments were carried out for three typical South African biomass samples (softwood chips, hardwood chips and sweet sorghum bagasse) to a weight loss of 30wt.%. During torrefaction, moisture, non-structural carbohydrates and hemicelluloses were reduced, resulting in a structurally modified torrefaction product. There was a reduction in the average crystalline diameter (La) (XRD), an increase in the aromatic fraction and a reduction in aliphatics (substituted and unsubstituted) (CPMAS 13C NMR). The decrease in the aliphatic components of the lignocellulosic material under the torrefaction conditions also resulted in a slight ordering of the carbon lattice. The degradation of hemicelluloses and non-structural carbohydrates increased the inclusive surface area of sweet sorghum bagasse, while it did not change significantly for the woody biomasses.

The present study is aimed at observing the variations, in space and time, of see of the important hydrographic parameters such as sea water temperature, salinity and Resolved oxygen within the coastal waters along the south-west coast of Indiametween Ratnagiri (17°OO*N,73°20'E) and cape comorin ( 8°10'N,77°30*E). Specific data relating to the process of upwelling and sinking was collected mainly to evaluate the extent and intensity of the vertical mixing processes active in the area under study. The study also attempted possible correlations between the observed parameters and the occurrence and migrations of some of the major pelagic fishery resources such as sardine,mackerel and anchovy in the area under study

Reducing fishing pressure in coastal waters is the need of the day in the Indian marine fisheries sector of the country which is fast changing from a mere vocational activity to a capital intensive industry. It requires continuous monitoring of the resource exploitation through a scientifically acceptable methodology, data on production of each species stock, the number and characteristics of the fishing gears of the fleet, various biological characteristics of each stock, the impact of fishing on the environment and the role of fishery—independent on availability and abundance. Besides this, there are issues relating to capabilities in stock assessment, taxonomy research, biodiversity, conservation and fisheries management. Generation of reliable data base over a fixed time frame, their analysis and interpretation are necessary before drawing conclusions on the stock size, maximum sustainable yield, maximum economic yield and to further implement various fishing regulatory measures. India being a signatory to several treaties and conventions, is obliged to carry out assessments of the exploited stocks and manage them at sustainable levels. Besides, the nation is bound by its obligation of protein food security to people and livelihood security to those engaged in marine fishing related activities. Also, there are regional variabilities in fishing technology and fishery resources. All these make it mandatory for India to continue and strengthen its marine capture fisheries research in general and deep sea fisheries in particular. Against this background, an attempt is made to strengthen the deep sea fish biodiversity and also to generate data on the distribution, abundance, catch per unit effort of fishery resources available beyond 200 m in the EEZ of southwest coast ofIndia and also unravel some of the aspects of life history traits of potentially important non conventional fish species inhabiting in the depth beyond 200 m. This study was carried out as part of the Project on Stock Assessment and Biology of Deep Sea Fishes of Indian EEZ (MoES, Govt. of India).

Continental shelf is of particular significance in marine geology , because it links the two basically different structural zones in the earth's crust; the continents and ocean basins. The shelf area has much wider importance in many fields of activity such as scientific, economic, social, political and strategic. The pace of development has ultimately put pressure on mankind to look for exploitable resources and accessibility to the continental shelf area and beyond. Added to the above, the developmental activities in the coastal area would readily and directly influence the innershelf sediments. This situation demands a thorough geological knowledge of the continental shelf area. Moreover, a successful management of the continental shelf zone requires an optimum data base on the physico-chemical nature of the shelf sediments. Although sedimentological studies were carried out along the western continental shelf of India, a well documented systematic study of the inner shelf off Trivandrum coast is still found to be lacking. Considering the physiographic settings and the vicinity of two renowned placer deposits at Chavara and Manavalakurichi, such a sedimetological inventory has become all the more vital. In view of the above, a research programme has been drawn up to account the salient sedimentological and mineralogical aspects of the innershelf and beach sediments between Paravur and Kovalam, Trivandrum district, Kerala (latitudes 8° 7'00" to 8° 47'45" and longitudes 76°43'00" to 77° 40'45"). The findings are presented in six chapters formatted to address the aim of this research.
