Development of antifouling ultrafiltration PES membranes for concentration of hemicellulose

A new approach for one‐stage facile membrane modification during non‐solvent induced phase separation (NIPS)‐process is proposed. The novelty of this study is that cheap and commercially available anionic high molecular polyacrylamide‐based flocculant (AHMPF) is applied for the first time as an additive to coagulation bath (CB). The series of polyethersulfone membranes were prepared using 0.05–0.3

Lyngsjö och de gyllene altarna

Artikeln kompletterar två tidigare texter i tidskriften Ale 2020: 2–3 om Lyngsjö i Skåne. Elisabeth Reuterswärd söker här bakgrunden till dopfuntens ovanliga motiv, medan Sten Skansjö förklarar utvecklingen i socknen över tid. Denna artikel uppmärksammar, att dopfunten har spår av bemålning, kommenterar kyrkans herrskapsgalleri, korrigerar upplysningarna om antalet gyllene altare i Norden, visar aThe article presents a supplement to two earlier texts in the periodical Ale 2020: 2–3 on Lyngsjö in Scania. Elisabeth Reuterswärd here seeks the background for the unusual motif of the baptismal font, where Sten Skansjö tries to explain the development in the parish over time. The present article draws attention to the fact that the font has traces of painting, comments on the upper gallery of th

Quality issues in georeferencing : From physical collections to digital data repositories for ecological research

Natural history collections constitute an enormous wealth of information of Life on Earth. It is estimated that over 2 billion specimens are preserved at institutions worldwide, of which less than 10% are accessible via biodiversity data aggregators such as GBIF. Moreover, they are a very important resource for eco-evolutionary research, which greatly depends on knowing the precise location where

Steady three-dimensional ideal flows with nonvanishing vorticity in domains with edges

We prove an existence result for solutions to the stationary Euler equations in a domain with nonsmooth boundary. This is an extension of a previous existence result in smooth domains by Alber (1992) [1]. The domains we consider have a boundary consisting of three parts, one where fluid flows into the domain, one where the fluid flows out, and one which no fluid passes through. These three parts m

Lack of Photon Antibunching Supports Supertrap Model of Photoluminescence Blinking in Perovskite Sub-Micrometer Crystals

Antibunching effect is typically observed in individual systems possessing photoluminescence (PL) blinking and vice versa. Contrary to this common perception, absence of antibunching in strongly blinking methyl ammonium led tri-iodide (MAPbI3) perovskite crystals of sizes from tens to hundreds of nanometers regardless of the excitation power density is observed. Antibunching effect does not appear

Glucose effectiveness : Lessons from studies on insulin-independent glucose clearance in mice

Besides insulin-mediated transport of glucose into the cells, an important role is also played by the non-insulin-mediated transport. This latter process is called glucose effectiveness (acronym SG), which is estimated by modeling of glucose and insulin data after an intravenous glucose administration, and accounts for ≈70% of glucose disposal. This review summarizes studies on SG, mainly in human
