The Barents Sea is a transition zone between the Atlantic and Arctic Ocean. ecosystem in this region highly variable, seasonal baseline of biological factors needed to monitor effects global warming. In study, we report results from investigations bacterial archaeal community late winter, spring, summer, early winter along transect through northern into Ocean east Svalbard using 16S rRNA metaba...

Often, different types of contaminants in wastewater are suspected adversely affecting the treatment efficiency a plant (WWTP). Therefore, it is essential to study effects newly synthesized substances on activity activated sludge microorganisms. The aim this was determine effect innovative biosurfactants, i.e., sophorolipids quaternary ammonium salts (SQAS), and three common micropollutants (MP...

Abstract Clinical trial endpoints include response/survival, but also treatment tolerance and clinical benefit. Few reports exist on the frequency type of disease-related symptoms functions treatment-associated symptomatic toxicities at initiation. The MD Anderson Symptom Inventory-Brain Tumor self-reports from patients baseline a initiation were retrospectively evaluated for presence severe ra...

A lab-scale ceramic membrane bioreactor (MBR) with active membrane-fouling control system was developed for the partial nitrification (PN) process. The in situ cleaning method applied to remove contaminants on surface of no interruption wastewater treatment. results showed that device increased critical flux and reduced gel layer resistance (Rg) internal (Ri) flat-sheet by inhibiting formation ...

<p style="text-align: justify;">A large number of articles in the field science education reflect on scientific literacy as main goal (SE), although often with varying viewpoints. Nevertheless, researchers have begun to highlight subject-specific teaching practices that are expected specifically enhance subject teaching, including biology. The aim this theoretical article is come consensu...

Ecophysiological interactions between the community members (i.e., nitrifiers and heterotrophic bacteria) in a carbon-limited autotrophic nitrifying biofilm fed only NH(4)(+) as an energy source were investigated by using a full-cycle 16S rRNA approach followed by microautoradiography (MAR)-fluorescence in situ hybridization (FISH). Phylogenetic differentiation (identification) of heterotrophic...

How do you feel when you hear the words " wastewater, " " sludge, " " sewer, " and " sewage " ? These words may make you feel uncomfortable. However, as Victor Hugo wrote in " Les Misérables, " these words are inevitably related to human society (16): " ... The history of men is reflected in the history of sewers. The Germoniae narrated Rome. The sewer of Paris has been an ancient and formidabl...
