A research to study the zooplanktonic population in relation some abiotic variables of Kribian coast waters was conducted from July December 2020 following a monthly sampling six (6) selected sites. The physicochemical parameters were determining out using standard methods. Concerning zooplankton, water collected at surface, trophogenic and tropholytic layers, then filtered through 64 µm plankt...

Alkali-activated (or geopolymer) membranes have emerged recently as an alternative for conventional ceramic membranes. Their main benefit is the simple and low-energy manufacturing not requiring sintering, thus potential clearly lower costs, while having largely similar performance materials. In this work, metakaolin, blast furnace slag, their mixture (representing typical low, high, medium Ca-...

In this work, a novel Pd–Ag double-skinned (DS-) membrane is used for the first time in conditions typical of propane dehydrogenation (PDH). This presents protective layer on top H2-selective one, which acts as shield against chemical deactivation and mechanical erosion under reaction conditions. While already been proven an efficient barrier fluidized beds, there no validation yet PDH reaction...

Our objective was to measure whey protein removal percentage from separated sweet using spiral-wound (SW) polymeric microfiltration (MF) membranes a 3-stage, 3× process at 50°C and compare the performance of with ceramic membranes. Pasteurized, Cheddar cheese (1,080 kg) microfiltered 0.3-?m polyvinylidene (PVDF) fluoride SW membrane 3×, 3-stage MF process. Cheese making processing were replicat...

This application note reports on the development of a calibration model, its validation and applicability for the determination of residual lactose in lactose-reduced milk and milk products using a Lactoscope FTIR Advanced (FTA) Instrument. The calibration model developed for milk was based on a set of 76 samples, including process samples, endproducts of various brands of skim milk, semi skim ...

Dried milk protein concentrate is produced from skim milk using a combination of processes such as ultrafiltration (UF), evaporation or nanofiltration, and spray drying. It is well established that dried milk protein concentrate (MPC) that contains 80% (MPC80) and greater protein content (relative to dry matter) can lose solubility during storage as a result of protein-protein interactions and ...

Membrane processes such as microfiltration, ultrafiltration, nanofiltration and reverse osmosis have been popular subject for researchers interested in water filtration system. One of the main problems with such membrane system is biofouling, which is caused by deposition or growth of microorganisms on membrane surface. One solution to this problem, as it has been used for many years now, is ch...

Verification of exposure to nerve agents is relevant because the health risks of even low level exposures have not yet been fully explored. Within this context it is important to verify non-exposure in order to reassure worried military personnel or citizens. Phosphylated butyrylcholinesterase is one of the most important biomarker to verify an exposure to nerve agents. Nerve agent adducts can ...

After the acceptance of our manuscript, we became aware an error in approach used to analyze bacterial community associated with Microcystis. We only removed DNA sequence reads from Microcystis after calculation relative abundance rather than before. In turn, may have introduced errors into results on composition ordination and hierarchical clustering. To assess this, re-computed clustering ana...
