The water balance is severely disturbed in post-mining landscapes like Lusatia/Germany. Mine waters (amd) enter the environment and spread in groundwater and surface waters. Groundwater containing high amounts of pyrite weathering products flows into receiving waters due to lignite mining for several years. The Chair of Wassertechnik & Siedlungswasserbau at the Brandenburg University of Technology Cottbus-Senftenberg/Germany has developed a subsurface rehabilitation method using microbial sulfate reduction over the [...]

Crohn’s disease is characterized by chronic intestinal inflammation that can result in significant morbidity and loss of intestinal function over time. Many novel treatments for Crohn’s disease are being developed, but a significant portion of patients still requires surgical therapy for structuring or penetrating disease. While the utility of esophagogastroduodenoscopy and ileocolonoscopy in inflammatory bowel disease patients is well established, new endoscopic techniques are being developed to help evaluate prev [...]

Many cells demonstrate variances in behavior due to their cell culture environment. To provide a mechanically-tunable, tissue-like environment, a 3D hydrogel for cell culture was formulated using collagen (Col) and hyaluronic acid (HA) to help provide a system for studying these dynamic cellular responses in a soft-tissue environment. A design of experiments was organized to study the effects of collagen concentration, HA fragment size, and Col: HA mass ratio on the hydrogel mechanical properties. Mechanical charac [...]

Tomato (Solanum lycopersicum L.) is the largest vegetable crop produced and consumed in the world. Tomatoes are a top source of Vitamin A and C, contain more dietary fibre, beta-carotene, iron, lycopene, magnesium, niacin, potassium, phosphorus, riboflavin, and thiamine. Tomatoes have a limited shelf life in ambient conditions and are highly perishable. It creates glut during the production season and becomes scanty during the off-season. Short shelf life, coupled with inadequate processing facilities results in he [...]

Research indicates that adults in the context of gender and sexual diversity (GSD) experienced more violence and discrimination than the rest of the population. GSD refers to all the diversities of sexual characteristics, sexual orientations and gender identity of a person or a group. To encourage the use of evidence-based interventions in health and social services, it is important to extrapolate from the scientific literature how mistreatment situations are managed in this context. A scoping review was conducted [...]

In the context of resource depletion and global warming, the energy transition has become a necessity. To provide a basis for analysis and to support countries in this transition, it is necessary to better understand this transition. The creation of a good measurement tool could help. This paper proposes a measure of national resilience through an analogy to kinetic energy. Preliminary results show that some countries have strong potential for resilience in the energy transition. Inequalities exist and still exist [...]

Cytomegalovirus (CMV) infection is a common and severe complication following allogeneic stem cell transplantation (ASCT) and requires effective preemptive antiviral therapy. Both oral and intravenous (IV) antiviral agents effectively reduce CMV viral load and achieve viral clearance. Studies comparing oral and IV anti-CMV preemptive treatment in ASCT patients with CMV reactivation showed a potential difference in treatment response and safety profiles between the two administration routes. We retrospectively compa [...]

Non-communicable diseases (NCDs) are responsible for two-thirds of premature deaths in Europe. This added to the European socio-economic scenario already weakened by the vital aging of the population, contributes to the loss of active individuals, weakening competitiveness and social and economic sustainability, thus making the prevention of NCDs a European objective. Preventing NCDs with the enrichment of the food environment using algae or their compounds, which are rich in nutrients and bioactivities, is an exce [...]

Background: The pathogenesis of nonalcoholic steatohepatitis (NASH) is thought to be multifactorial, and oxidative stress may play an important role in the development of NASH. Peptides obtained by enzymatic decomposition of mackerel (EMP) including selenoneine were recently reported to possess antioxidative activity. Thus, EMP can be a candidate dietary strategy for the prevention of NASH. [...]

The paper analyses the performance of a spherical solar collector compared to the efficiency of a flat-plate solar collector, which is the type of solar collector that does not use a tracking system in collecting solar radiation for energy conversion. Spherical solar collector benefits from a constant value of the angle of incidence, which optimizes the solar radiation that strikes the absorber of the solar device and maximizes the energy collection. Besides, the spherical geometry has a larger area for equal dimen [...]
