2014 An atomic beam source for negative polarized lithium ions is operated at the Heidelberg EN-Tandem since 1974. A highly efficient surface ionizer is used. Vector and tensor polarized beams of 6Li (I = 1) and 7Li (I = 3/2) have been produced with currents up to 150 nA of Li3+ at the target. The second rank tensor polarization of both beams is calibrated absolutely. Preliminary results of pro...

OBJECTIVE To explore genetic and environmental influences on individual differences in autistic traits in early adulthood and to test if there is assortative mating (nonrandom partner choice) for autistic traits in the general population. DESIGN Twin family study using structural equation modeling. SETTING Population-based twin family sample from the Netherlands. PARTICIPANTS Twins aged 1...

In this study, several kraft pulps were produced by kraft pulping of fastgrowing Eucalyptus with a wide range of cooking conditions. The dependences between pulp yields and some pulp properties, namely, kappa number, HexA contents, and cellulose viscosities, were well investigated. It was found that kraft pulp yields linearly decreased with the reduction of HexA-free kappa number in two differe...

Patchouli is the largest non-oil export commodity among essential oil exports in Indonesia. However, quality of patchouli Indonesia considered to be very low. Traditional distillation carried out a small capacity and uses simple method based on large difference boiling points or one volatile components. This process produces poor such as acid number more than 8, dark oil, alcohol less 30%, high...

The speed in distributing the products of industry is influenced by production produced itself. SMEs know that ECO one manufacturing industries engaged food manufacturing. there are obstacles (problems) experienced, namely occurrence inequality between capacity tofu can be and demand for must met. purpose this study to increase Tofu Eco terms increasing working time. method used research dynami...

background and purpose: phenol and derivatives are common pollutants of drinking water which are blamed for crucial adverse effects such as poisoning, cancer, and malformation. in this study, an activated carbon of miswak’s root (mr) was used for the removal of phenol from aqueous solutions as a low-cost and high surface adsorbent. materials and methods: adsorption experiments were then conduct...

Fibre can enhance the mechanical properties of cement-based composites, but fibre also degrades their workability. However, quantitative effects fiber content and length-diameter ratio on alkali-activated materials are still unclear. Various aspect ratio, volume fraction polyvinyl alcohol (PVAF), various water-binder were employed to prepare a total 26 groups reinforced composite (FRAAC). The i...

We investigated the interaction between activated cat polymorphonuclear neutrophils (PMNs) and coronary vascular endothelial cells in vitro. It was shown that 1) 90 minutes of low-flow perfusion without reperfusion had no deleterious effects on endothelium-dependent vasodilation, whereas 90 minutes of low-flow perfusion and 20 minutes of reperfusion with a blood cell-free solution induced a 20-...

The dry pulp direct kneading method is an industrially viable, low-energy process for manufacturing cellulose nanofiber (CNF)-reinforced polymer composites, where the chemically modified pulps are nanofibrillated and uniformly dispersed in matrix during melt compounding. In present study, fibers of various sizes ranging from surface-fibrillated (20 μm width) to fine CNFs nm were prepared softwo...
