The initiative of implementing Internet-based solutions for the integration of the supply chain of materials will not succeed if there is not assurance of collaboration and communication among the parties in the construction business. Neither EDI nor web-based supply chain applications can facilitate both the process integration and flexibility required by the construction processes practiced t...

A brief analysis is presented of how heat transfer takes place in porous materials of various types. The emphasis is on materials able to withstand extremes of temperature, gas pressure, irradiation, etc. i.e. metals and ceramics, rather than polymers. A primary aim is commonly to maximize either the thermal resistance (i.e. provide insulation) or the rate of thermal equilibration between the m...

NDT is mainly discussed as an engineering technology to detect, classify and size material imperfections, called material defects. Lattice defects and microstructure inhomogeneities like vacancies, dissolved atoms dislocations and precipitations are normally not discussed as defects but they are influence parameters which mainly predict the macroscopic properties, the physical properties as wel...

Contamination and materials degradation are among the highest risks associated with the deployment of high intensity solid-state laser systems. Although high intensity laser induced optical damage has been studied for decades, the field is still in its infancy. There is little concrete information concerning the relationship of contamination and laser induced optical damage. Further, little inf...

W generation and resource shortages have long been recognized as two of the greatest challenges human society is facing. In the early 1970s, the Club of Rome, a group of pioneering global thinkers, predicted in their milestone book The Limits to Growth that “if the present growth trends in world population...pollution ... and resource depletion continue unchanged, the limits to growth on this p...

New generation medical textiles are an important growing field with great expansion in wound management products. Virtually new products are coming but also well known materials with significantly improved properties using advanced technologies and new methods are in the centre of research which are highly technical, technological, functional, and effective oriented. The key qualities of fibres...

OBJECTIVE To evaluate whether post-exposure measures referred by dentists and dental assistants are in line with those recommended by Brazilian health authorities. METHODS An epidemiological survey was carried out in a city of Southern Brazil, in 2003. Subjects (289 dentists and 104 dental assistants) were selected through random systematic sampling. Data were collected through self-reported ...

commodity groups. The study may be accomplished over a period of time, until all commodity groups have been considered. The study should address functional requirements, activity levels of commodity groups and individual items, and potential impacts on local suppliers and small and disadvantaged businesses. An industrial relations analysis on existing labor relations and union contracts may als...

Diarrhoea, pneumonia, measles, malaria and malnutrition account for more than 70% of deaths and health facility visits among children under 5 years of age in developing countries. A number of programmes in WHO and UNICEF have developed an approach to the integrated management of the sick child, which is being coordinated by WHO's Division for the Control of Diarrhoeal and Acute Respiratory Dise...
