Though many options exist, the application of integrated PV systems in mass produced consumer products is still unusual and rare [1]. Therefore, to date, design and manufacturing aspects of product-integrated PV systems have been explored only to a very limited extent. The requirements for the design of consumer products are evidently different from those for PV systems. Moreover, product desig...

Concrete is a long-lasting and less energy consuming construction material than steel and Aluminum. However, the concrete industry is the single largest consumer of natural resources. Several places around the world are facing faster rates of depletion of the resources needed for the manufacturing of portland cement, mining of aggregates, and water for making concrete. Each one of these materia...

The use of industrial by-products of the vegetable oil industry as ductility increasing additives of polylactide (PLA) was investigated. Vegetable oil deodorization condensates were melt-blended by twin-screw extrusion up to a maximum inclusion quantity of 20 wt% without preliminary purification. Sample films were obtained by single screw cast extrusion. Compounded PLA films featured largely im...

Thermoplastic proteins can be prepared by using a suitable plasticizer and by using a proper combination of mechanical shear and heat. The amount of plasticizer and the processing conditions leads to materials with different chemical and physical properties which can be optimized to produce films, fibers and foams. The effect of type and amount of plasticizer, and the effect of processing condi...

With the continuous development of economy and science, medical instrument entered the digital and informational age. Conflicts between the urgent requirement and severe lack for ergonomics in the industrial design of medical instrument products became increasingly fierce. In the present paper, we attempted to use the research achievements in the area such as product form design theory, ergonom...

This work is focused on the study of different microorganisms to obtain a high level of lipase. It was selected 6 different microorganisms: Geotrichum candidum NRRLY-552, Geotrichum sp., Fusarium oxysporum and three wild yeasts from Brazil rainforest. Fermentation carried out using agro industrial by-products like corn steep liquor and protein hydrolysed in shaken flasks under different conditi...

Arsenic and its adverse effects on the environment and society impose a serious risk as it can be observed in cases such as India, Bangladesh, Vietnam, Nepal, and Cambodia. These problems can arise from geochemical processes but also man-made activities like mining and processing of minerals (Copper, Gold, Cobalt, Nickel and Uranium) that may further contribute to the risk of environmental disa...

Concrete is a building material, which in many cases fulfills the requirements for high sustainability. Industrial by-products, e. g. fly ash or silica fume, are used for improving the fresh and hardened properties of concrete, blast furnace slag for cement production, but also concrete by itself can be used as aggregate to produce strong and durable concretes. In this contribution examples of ...

Chloromethylisothiazolinone (MCI) and methylisothiazolinone (MI) have been widely used as preservatives in cosmetics, household products and industrial products since the late 1970s. First cases of contact allergy to the MCI/MI combination were noted in 1980-1982 in Sweden. Then, a significant increase in the frequency of sensitization to these compounds was observed in many European centers. T...

To identify and discuss sources of delay in the new product development process at an industrial products firm, data were collected during 11 bi-weekly project review meetings at which 42 different projects were discussed. The highest priority projects were designs for a new venture into European markets. It was suggested that manager selection, vendor monitoring, attention to physical engineer...
