Since the 70's, various researches have been undertaken to concentrate the solar flux on solar panels. In the 90's, concentrators with low concentration ratio appeared (C ¡ 2.5), easily adapted to classical panels. From early 2000, the first commercial spacecrafts with such a technology were launched. Nevertheless, a gradual loss of power appeared and deep investigations concluded that this was due to various causes: off-pointing, darkening and wrinkling of the reflective surfaces. From this incident, attention was paid to the contamination of the reflectors and more particularly to their operational temperature. Recently, in 2005, JAXA launched its small REIMEI scientific spacecraft, with two solar arrays equipped with a single lateral reflector. The good results achieved have triggered a new initiative in Europe to study a new concept of lightweight concentrator. The first results of this study including contamination and thermo-merchanical issues are presented.

Filling fats are used in bakery and confectionery applications. These fats are made up of complex mixtures of triacylglycerols (TAG). The crystallization, melting behaviour and polymorphic stability of fat blends are determined by the behaviour of the TAGs that they contain. Filling functionalities are influenced by their fat composition but also by the processing conditions used for crystallization. In this study, the crystallization behaviour of fat blends, all based on shea stearin as hard fat (which is high in 1,3-distearoyl-2-oleoyl glycerol (SOS)) combined with either sunflower oil, shea olein or rapeseed oil, were investigated by means of pulsed nuclear magnetic resonance (pNMR), differential scanning calorimetry (DSC) and X-ray diffraction (XRD). Blends containing either 30 or 40% shea stearin combined with one of the soft fats were selected as they met the criteria required for filling fats. Under static isothermal conditions (at 10°C, 15°C or 20°C), a two-step crystallization was observed for those blends, which can be explained by polymorphic transitions from α-form into more stable forms. All the selected blends exhibited different crystallization mechanisms according to the TAG composition of the liquid phase and their complementarity with TAG from the solid phase. © 2015 WILEY-VCH Verlag GmbH & Co.

Early effects of HPV (human papillomavirus) vaccination are reflected by changes observable in young women attending cervical cancer screening.The SEHIB study included HPV geno-typing of 6000 continuous and 650 pathological cervical cell specimen as well as biopsies, collected from women in Belgium in 2010-2014. Data were linked to vaccination status.HPV vaccination offered protection among women aged <30years against infection with HPV16 (vaccine effectiveness [VE]=67%, 95% CI: 48-79%), HPV18 (VE=93%, 95% CI: 52-99%), and high-risk HPV (VE=16%, 95% CI: 2-29%). Vaccination protected also against cytological lesions. Vaccination protected against histologically confirmed lesions: significantly lower absolute risks of CIN1+ (risk difference [RD]=-1.6%, 95% CI: -2.6% to -0.7%) and CIN3+ associated with HPV16/18 (RD=-0.3%, 95% CI -0.6% to -0.1%). Vaccine effectiveness decreased with age. Protection against HPV16 and 18 infection was significant in all age groups, however no protection was observed against cytological lesions associated with these types in age-group 25-29.The SEHIB study demonstrates the effectiveness of HPV vaccination in Belgian young women in particular in age group 18-19. Declining effectiveness with increasing age may be explained by higher tendency of women already exposed to infection to get the vaccine.

Most impressive about the site is its aesthetic. With its sleek design and intuitive layout, the site pushes visual and content standards for the localization industry. The new release features a full content library of case studies, eBooks, and articles on current events affecting the localization industry, and international business as a whole. The site's new blog, ULG Daily, features articles written by ULG's staff of localization experts. "The new website is an amazing accomplishment that we're very proud of," said ULG President, Kristen Giovanis. "We are a progressive company when it comes to technology, and ULG's new website is a perfect example of that." The website was unveiled to ULG by its designers on Nov. 1, when it went live. The new site is the latest example of ULG's initiative to develop technology solutions for clients in a variety of industries. After ULG acquired KJ and Merrill Brink International in June 2016, the company formed a research and development team, and just last month released its new machine translation technology, OctaveMT. United Language Group is one of the largest translation and localization providers in the world, with offices based in 5 countries on 3 continents. ULG applies innovative technology and language expertise to drive translation and localization quality for our clients around the world, in industries like life sciences, legal, IT, finance, and manufacturing.

The effects of machine traffic were assessed on a Luvisol in a temperate climate area in Belgium. Soil samples were taken from topsoil (0.07-0.25 m) and subsoil (0.35-0.50 m), on plots under long-term reduced tillage (RT) and conventional tillage (CT). Cone index (CI), bulk density (BD) and precompression stress (Pc) were chosen as indicators of mechanical strength. Mercury intrusion porosimetry was used to characterise the soil microporosity structure. It was presented in two forms: (i) cumulative pore volume vs. equivalent pore radius r, from which four classes of porosity were defined: r< 0.2 μm, 0.2 ≤ r< 9 μm, 9 ≤ r< 73 μm and r≥ 73 μm and (ii) pore-size distribution (PSD). In the reference situation where there had been no recent passage of machines, the voids with 0.2 ≤ r< 9 μm were the most important class in RT topsoil. The voids with r≥ 73 μm represented the main porosity class in the topsoil of CT. In the subsoil, for both tillage systems, the porosity was almost equally distributed between voids with 0.2 ≤ r< 9 μm and voids with r greater than 9 μm.Machine traffic was carried out when the soil water content was close to the optimum Proctor. Although unfavourable, these wet conditions often occur during the beet harvesting period in Belgium. The highest modifications in soil structure (increase in BD and Pc, reduction of macroporosity r≥ 73 μm) were observed in the topsoil of CT. More limited modifications were noticed in the soil structure of RT topsoil and subsoil layers but these latter are problematic in that the soil would no longer be loosened by subsequent tillage. These modifications could lead to soil consolidation as a result of wheel traffic year after year. © 2015 Elsevier B.V.

The Belgian Blue cattle breed is a core example to illustrate the notion of lock-in in animal production. We study in this paper the situation of another hyper specialized breed, the Belgian Texel sheep, and we re-question an animal genetic resources management set-up, crossing both approaches of lock-in and of localization of agrifood systems. This work leads us to show how the Belgian Blue is a model for Belgian Texel stakeholders, even if the lock-in modalities are different. We discuss the question of adaptation and adaptive capacities of local breeds. Finally, we underline the importance of questioning what is the meaning of "local" for the stakeholders. © 2016 A.

With the introduction of the use of Laser assisted surgery, refractive eye surgery knows a very large success. Surgery of well being, it requires that an extensive information is delivered to the patient concerning the benefit and possible side-effects of the available treatments. This information process may reduce the frequency of negligence claims relating to Laser eye surgery.

Hereditary Hemorrhagic Telangiectasia (HHT) also known as Rendu-Osler disease is a group of related disorders inherited in an autosomal dominant fashion and characterized by the development of arteriovenous malformations (AVM) in the skin, mucous membranes, and/or internal organs such as the brain, lungs, and liver. The prevalence of liver involvement is clinically estimated between 8 and 31 percent. It can be revealed by the following clinical signs : ascites, edema of the lower extremities, abdominal pain, dyspnea, and, rarely, hepatic encephalopathy and gastrointestinal bleeding associated with portal hypertension. This case illustrates the highlight of liver damage revealed by an ammonia encephalopathy associated with iconographic anomalies on ultrasonography and magnetic resonance liver as part of Rendu-Osler disease.
