Abstract:

Food additives, drugs and growth-enhancing compounds are prominent tools in the production of sufficient quantities of affordable food. Thus, food safety has become a main concern of many countries for protection of their population's health. Analytical chemical measurements are increasingly important to ensure consumer protection, particularly in the field of antibiotic residues. International comparability and reliability of measurement results can be achieved by establishing and demonstrating the metrological traceability of those results to the International System of Units (SI). To ensure

Abstract:

Formaldehyde, an important feedstock in industrial processes and manufacture, is widely present in numerous consumer products. Emitted by many types of consumer products and indoor materials, indoor air can contain high concentrations of formaldehyde. Exposure to formaldehyde is hazardous to human health. Thus knowledge of formaldehyde mass-transfer properties is critical to efforts to reduce formaldehyde emissions and establish related standards and regulations. The primary objectives of this project include: 1) documenting and validating procedures and methods for analyzing and measuring

Abstract:

Volatile organic compounds (VOCs) and semi-volatile organic compounds (SVOCs) constitute important classes of indoor contaminants. Emissions of VOCs and SVOCs from myriad building materials and consumer products cause high indoor concentrations with health risks that may be orders-of-magnitude greater than outdoors. The need to control VOC and SVOC emissions from interior materials and thereby reduce indoor concentrations is made more urgent by the prevailing drive for air-tight, energy efficient buildings. To develop low-emission products, emission rates are usually measured in emission chamb

Chapter 4 demonstrates that 'tradition' (II Thess. 2:15; 3:6) is not a post-Pauline development but a characteristic of the undisputed letters of Paul. By examining the terminology of tradition in the New Testament and Apostolic Fathers, and by a fresh identification the traditions in I Corinthians, I Thessalonians,

Earth was one of earliest materials used for construction of human shelters. In its raw state, it does not meet the basic physical properties required of a material for use in construction, i. e. compressive strength and durability (water resistance). The raw material can be stabilised to improve these properties through chemical, physical and mechanical methods. Chemical and physical methods involve mixing and compacting the earth with various materials to increase its compressive strength and reduce its propensity to shrink and swell. Mechanical methods of stabilisation involve only compacti

Abstract:

A participação de laboratórios nacionais em ensaios de proficiência internacionais expõe a fragilidade técnica na produção de Materiais de Referência (MR) no Brasil, devido à insuficiência desse tipo de material, tanto para ensaio de proficiência quanto para a rotina laboratorial. A capacitação de um Laboratório Central de Saúde Pública (LACEN) como produtor de MR, em bioquímica laboratorial, permitirá a disponibilização para toda rede de laboratórios públicos do estado de São Paulo, contribuindo na melhoria da qualidade das análises laboratoriais em bioquímica.

Abstract:

Os ensaios de proficiências são amplamente utilizados para avaliar a capacidade analítica de laboratórios e também como parte dos processos de acreditação. Por esta razão, são importantes ferramentas para o controle dos resultados analíticos obtidos nos laboratórios que atuam diretamente com as empresas exportadoras de pescado. No Brasil não há provedores de ensaios de proficiência para metais potencialmente tóxicos em pescado. Neste trabalho serão descritos todos os passos utilizados para a produção de materiais de referência a serem utilizados em um estudo piloto de ensaios de proficiência p

Working on Environmental Education with Children can become outstanding when this work is different in relation to what we are presented on the curriculum and on school practices, where it is restricted on being sporadic, superficial and misunderstood, underestimating our subject the children , who are considered unable to understand deeper concepts, and denying any possibility of self dialogue or reflection upon the information that surrounds them. The curriculum is only focusing the celebration of important dates, which are restricted to one day, without any deeper debate concerning knowled

Abstract:

This study is a venture in urban history in that although housing has been the subject of a number of recent studies, little attempt has been made within the British urban history framework to give serious study to what lies behind the architectural facade, the material domestic culture of an urban community. An important objective of this study is to examine the material culture of domestic dwellings in early Victorian Grahamstown, also referring to other parts of the Cape Colony. Where possible these facts are related to the occupants of the dwellings. No community, urban or rural, can be di
