Grape seed oil was isomerlzed on CaO in (HOCH 2) 2 to Ca conjugated linolate (5.6%), while a fish oil was lowtemp, crystd. to increase content of eicosapentaenoic and docosahexaenoic acids to 41.5%. Both prepns. were supported on a com. humus-mineral sorbent and used as a supplement cows diet at 400 g/head/day to modify the fatty acid profile of milk fat. The share of conjugated dienes of cis-9, trans-10 and trans-10, cis-12 linoleic acids C18:2 in milk fat increased by 55-150% and trans-11 vaccenic acid C18:1 by 62-110% as a result of the diet improvement. Transfer of the fatty acids profile from milk to rennet cheese was also confirmed. Source

In this project proposal, industry wide harmonized test procedures for PEFC stacks shall be developed and validated. The proposal builds on experiences gained in the FCTESTNET, FCSTEQA series of projects taking up the methodology developed there and expanding it to the test of PEFC stacks. Furthermore, experiences of individual consortium members have long time experience in international standardization. Performance / functional, durability and safety outputs for vehicle propulsion, stationary and portable applications shall be addressed. Generic test modules addressing the effects of outputs to the variation of a single test parameter shall be defined and experimentally validated on a stack level. From these building blocks, selected application oriented test programs shall be derived and validated as well. A two phase approach is pursued starting with an initial selection and definition phase followed by experimental validation. Subsequently, a review is carried out followed by a second validation phase. The consortium mainly consists of experienced research organizations, all working in close contact with and providing testing services to industry. The test modules and test programs are expected to be methodologically sound and independent. Contact to industrial practice will be established by the implementation of an industrial advisory group consisting of selected key stakeholders along the value chain of the fuel cell industry. The consortium will liaise with international standardization activities and contribute to the improvement of existing standards by pre-normative research and if deemed necessary initiate new work item proposals on performance and endurance testing of PEFC stacks.

The synthesis of a novel compatibilizer from a styrene-isoprene-styrene block copolymer and 9-borabicyclo [3,3,1]-nonane (9-BBN) and its application in compatibilizing thermo-dynamically immiscible PE-LD/PS and PP/PS mixtures (Figs. 2, 3) has been presented. The influence of the compatibilizer (2 or 6 wt. %) on the structure of the obtained composites was evaluated. SEM micrographs of the fractured surfaces of the products indicated a relatively better interphase adhesion of the compatibilized compositions (Figs. 4 and 5). TG and DSC thermal analysis (Figs. 6 and 7; Table 1) confirmed an interaction of the crystalline structure of the studied polyolefins as well as an increased thermal resistance of the compatibilized mixtures. The application of the synthesized SIS/9-BBN modifier enhances the interface adhesion of the studied polymeric systems in a crucial manner and enhances their mechanical parameters. Source

Maleate-doped high d. polyethylene and ethylene/n-octene copolymer were prepd., blended by extrusion with high d. polyethylene and processed to thin wall products with functional channels studied for their structure as well as mech. and thermal properties. The addn. of modifiers resulted in increasing the tensile, flexural and impact strengths. A small decrease in the melting temp, and small increase in the cryst. temp, were also obsd. Source

According to the Article 2(9) of Regulation (EC) No 1907/2006 of The European Parliament and of The Council of 18 December 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), polymers are exempt from registration and evaluation requirement. However, in accordance with the preamble of REACH Regulation "Polymers should be exempted from registration and evaluation until those that need to be registered due to the risks posed to human health or the environment can be selected in a practicable and cost-efficient way on the basis of sound technical and valid scientific criteria". The article discuss in brief the results of analysis performed for The European Commission, which were presented in The Final Report. It aims to point out, how the registration process of polymers or some types of polymers could appear soon in EU and what producers, importers and downstream users of polymer could expect. Source
