Additive Manufacturing (AM) is a technology that, while removing many of the constraints of traditional manufacturing, imposes some new constraints of its own. Because of this, engineers and designers need to be taught a new set of skills in design for additive manufacturing (DfAM) in order to become competent in designing parts that maximize the benefits offered by AM. Around the world, universit

The usual pigmentation pattern in mammalian skin consists of fixed melanocytes in the basal layer of the epidermis, supplying keratinocytes with melanosomes. We observed that the glabrous skin (rhinaria and footpads) of dogs deviates from this pattern. In dogs, melanocytes are found in both the dermis and epidermis. The epidermal melanocytes are situated in the intercellular spaces of the basal an

BACKGROUND: The FORS histo-blood group system was described in 2013 and much remains to be investigated regarding its genetic and immunohematologic characteristics, as well as its clinical importance. While presence of the c.887G>A-mutated GBGT1 gene, which results in FORS1 glycosphingolipid expression on human red blood cells (RBCs), is rare in the populations tested so far, naturally occurring a

The fate of pollutants in rivers is mainly affected by the longitudinal dispersion coefficient (Kx). Thus, improved Kx estimation could greatly enhance the water quality management of rivers. In this regard, evolutionary polynomial regression (EPR) was used to accurately predict Kx in rivers as a function of flow depth, channel width, and average and shear velocities. The predicted Kx by EPR model

1. IntroductionThe end of the 20th century was marked by the start of the third and so far final wave of biotechnology, the so-called white biotechnology, aiming to substitute chemical processes based on C2/C3 chemistry of oil and gas by biotechnological processes. The standard conversion process in biotechnology is fermentation, which is used to produce a wide range of bulk products such as antib

Dextrose syrups are produced from starch by liquefaction combined with saccharification. In the conventional production process, rotary vacuum filters (RVFs) with a diatomaceous earth (kieselguhr) coating as filter aid are often used for removal of the so-called mud phase after the liquefaction and saccharification step. This mud phase consists of insoluble impurities and suspended solids such as

In heat exchanger and membrane processes fouling stands for a significant part of the running costs such as e.g. down time for cleaning, consumption of cleaning chemicals, water and energy and contributes also to a shortened equipment life time. It is therefore one of the major challenges in the process industry. The first part of the presentation will give a general introduction into fouling in h

We trapped birds on the island of Capri, SW Italy, during February and earliest March 2002-2004 and in November-December 2004. The trapped birds were ringed, and common biometrical parameters measured. In total 247 birds of 17 species were trapped, a rather limited number, whereof c. 70% were either European Robins Erithacus rubecula, Blackcaps Sylvia atricapilla, Sardinian Warblers Sylvia melanoc

High-energy surface X-ray diffraction (HESXRD) provides surface structural information with high temporal resolution, facilitating the understanding of the surface dynamics and structure of the active phase of catalytic surfaces. The surface structure detected during the reaction is sensitive to the composition of the gas phase close to the catalyst surface, and the catalytic activity of the sampl

The content of minerals and dietary fibre in different fractions of oats was investigated. The oat kernel (pericarp, testa, germ, aleurone, endosperm), accounting for 70 % of the oat seed, had a dietary fibre content of 11·5 g/100 g (dry weight basis); of this 23 % was soluble fibre components, mainly β-glucans. In contrast to most other cereals the amount of soluble fibre was distributed througho

Intestinal fermentation of dietary fiber from oat husk, bran, and white flour and a commercial oat bran was investigated through balance experiments in rats. Both solubility and monomeric composition of the fiber differed widely. Fiber from husk was only 0.5% soluble and nearly completely resistant to fermentation whereas fiber from bran (38% soluble) and white flour (24% soluble) was more ferment

This article addresses the question of whether globalization impacts individual preferences to exclude immigrants from national welfare systems ('welfare chauvinism'). Intergroup contact theory and arguments from the 'new cosmopolitanism' debate suggest that cross-border social contacts ('social globalization') foster a willingness to include and accept newcomers. However, group conflict theory su

The phenomenon of socio-economic insecurity is widely discussed in contemporary public and academic discourse. However, it is unclear how objective socio-economic and institutional conditions affect subjective feelings of insecurity. Based on a review of the relevant literature, we hypothesize that objective contextual factors of labour market characteristics, levels of social protection and level

In the current discourse it is frequently stated that in the course of European integration and globalisation we witness more intensified and more frequent transactions spanning across national borders. These assumptions relate not only to transactions in the economic sphere or to forms of political co-operation, but to the individual lifeworlds as well. Yet concerning the latter dimension, resear

The article explores the extent to which the German population is involved in transnational networks of personal relationships. It is argued that ongoing processes of globalization have weakened the social cohesion of nation-states and engendered more and more border-crossing transactions. In the paper, key empirical indicators are presented to demonstrate the increased transnational interdependen

Within the scope of the debate surrounding globalization, ever increasing attention is being directed to the growth of border-crossing social relations and the emergence of transnational social spaces on the micro-level. In particular, the question of how these border-crossing interrelations influence the attitudes and values of the people involved causes some controversy. Some assume that the inc

Gas turbine systems are predominantly designed to be fuelled with gaseous fuels within a limited Wobbe index range (typically HHV=45-55 MJ/Nm3 or 1200-1480 Btu/scf). When low calorific fuel gases are fired, the engine will be forced to operate outside its design envelope. The added mass flow will typically raise the cycle pressure ratio and in two-shaft designs also raise the gas generator shaft s
