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
Context. Spectroscopy across spatially resolved stellar surfaces reveals spectral line profiles free from rotational broadening, whose gradual changes from disk center toward the stellar limb reflect an atmospheric fine structure that is possible to model by 3D hydrodynamics. Aims. Previous studies of photospheric spectral lines across stellar disks exist for the Sun and HD 209458 (G0 V) and are n
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
Aims: We aimed to evaluate the impact of delay from diagnostic pre-hospital electrocardiogram (ECG) to wiring of the infarct-related vessel (ECG-to-wire) >120 minutes on cardiovascular magnetic resonance (CMR) markers of reperfusion success and clinical outcome in patients with ST-segment elevation myocardial infarction (STEMI). Methods and results: We included 1,492 patients in the analyses of cl
Many Frankia strains are pigmented and presumed to produce melanin. However, melanin biosynthesis has yet to be rigorously characterized in Frankia. This study was initiated to determine whether or not Frankia strain CeI5 produced melanin and to identify the biochemical pathway of pigment production. Frankia strain CeI5 first produced a dark pigment in mycelial and other tissue and then in the liq
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
We perform a land-surface model intercomparison to investigate how the simulation of permafrost area on the Tibetan Plateau (TP) varies among six modern stand-alone land-surface models (CLM4.5, CoLM, ISBA, JULES, LPJ-GUESS, UVic). We also examine the variability in simulated permafrost area and distribution introduced by five different methods of diagnosing permafrost (from modeled monthly ground
The sharing economy has many faces, and it has taken our societies by storm. For many people, it has quickly become a norm to book accommodation via AirBnB, or to think sharing instead of owning when it comes to products of their everyday lives. The tourism industry has seen many adaptions towards a sharing economy, one of them being a new way of conducting guided tours.

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
Over the last two decades the market for membrane technology in the food industry increased to a market volume of approx. € 50 million and is now the second largest industrial market for membranes after municipal water treatment in Germany. The key membrane technologies in the food industry are the pressure driven membrane processes; microfiltration, ultrafiltration, nanofiltration and reverse osm

The starch and yeast industries are two key sectors of the European food industry, with annual turnovers of approx. € 4 billion and € 500 million, respectively, in Europe alone. The production processes in the starch and yeast industries are still dominated by conventional separation processes such as evaporators, separators and rotary vacuum filters (RVFs), and membrane processes are only rarely
Membrane applications have established themselves in both the production and water loop of the starch-based sweetener industry. This presentation will give an overview of membrane opportunities in the starch-based sweetener industry is given. In the first part of this paper, the membrane opportunities in the production loop of starch-based sweeteners will be generally discussed and application stu
Conventional separation processes such as evaporators and separators often compete directly with membrane processes, i.e. microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO). The aim of this lecture is to highlight the potentials of combining membrane processes and conventional separation processes by the means of process synergies. In the first part of the lec
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
Rotary vacuum filters (RVFs) with adiatomaceous earth (kieselguhr) coatings as filter aid are the most established technology for the removal of the so-called mud fraction after liquefaction and saccharification in the production of starch-based sweeteners. The RVFs is an open process which is further associated with the use of filters resulting in an increasing disposal challenge. Based on this t
Due to increasing oil price and environmental concerns, current European initiatives are aiming to increase the share of Biofuel used for transportation from approx. 2 % (2005) to 5.75% in 2010. The production capacity of bioethanol in Germany alone has therefore to increase during this period from 0.7 mio. m³ to 1.8 mio. m³ 1. The feed stocks of current bioethanol concepts are sugar and starch
