Abstract:

Biomolecular condensates (BMCs) exhibit physiological and pathological relevance in biological systems. Both liquid and solid condensates play significant roles in the spatiotemporal regulation and organization of macromolecules and their biological activities. Some pathological solid condensates, such as Lewy Bodies and other fibrillar aggregates, have been hypothesized to originate from liquid condensates. With the prevalence of BMCs having functional and dysfunctional roles, it is imperative to understand the mechanism of biomolecular condensate formation and initiation. Using the low-compl

Abstract:

The Polycomb group (PcG) complex PRC1 localizes in the nucleus in condensed structures called Polycomb bodies. The PRC1 subunit Polyhomeotic (Ph) contains an oligomerizing sterile alpha motif (SAM) that is implicated in both PcG body formation and chromatin organization in Drosophila and mammalian cells. A truncated version of Ph containing the SAM (mini-Ph) forms phase-separated condensates with DNA or chromatin in vitro, suggesting that PcG bodies may form through SAM-driven phase separation. In cells, Ph forms multiple small condensates, while mini-Ph typically forms a single large nuclear

Abstract:

Membraneless organelles containing the enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) are a common feature of organisms utilizing CO2 concentrating mechanisms to enhance photosynthetic carbon acquisition. In cyanobacteria and proteobacteria, the Rubisco condensate is encapsulated in a proteinaceous shell, collectively termed a carboxysome, while some algae and hornworts have evolved Rubisco condensates known as pyrenoids. In both cases, CO2 fixation is enhanced compared with the free enzyme. Previous mathematical models have attributed the improved function of carboxysomes to

Abstract:

The Drosophila PRC1 complex regulates gene expression by modifying histone proteins and chromatin architecture. Two PRC1 subunits, PSC and Ph, are most implicated in chromatin architecture. In vitro, PRC1 compacts chromatin and inhibits transcription and nucleosome remodeling. The long disordered C-terminal region of PSC (PSC-CTR) is important for these activities, while Ph has little effect. In cells, Ph is important for condensate formation, long-range chromatin interactions, and gene regulation, and its polymerizing sterile alpha motif (SAM) is implicated in these activities.

Abstract:

The pH of wastewater needs to remain between 6 and 9 to protect water organisms. Condensates from a gas condensing boiler have a pH value of about 3. An optimal way to neutralize the acid condensate is to use cheap material such as dolomite. An old-style neutralization box (NB) was tested with a standard faction of dolomite. However, it did not sufficiently neutralize the condensate. Therefore, several tests were performed involving changes to the construction of the neutralization box, a finer fraction of dolomite and aerating the condensate in the neutralization box. In summary, a new NB tec

Four types of reverse osmosis membranes (LP, ULP, XLP and FR) were used for the treatment and reuse of the pharmaceutical condensates. The desalination rate and removal of TOC with pH 6.8 is significantly higher than pH 3.2 for all of the four membranes. When the pH is 6.8 the FR reverse osmosis membrane has the highest desalination rate, removal of TOC, permeate flux and the lowest transmembrane pressure, and it is energy conservation and not easy to be contaminated. So the FR reverse osmosis membrane is Suitable for the treatment of pharmaceutical condensate.

Nutrient redistribution between areas with a structural pig slurry surplus and those with a shortage, is limited by the high cost of transportation and spreading, due to the high water content in slurry (more than 90%) and its relative low nutrient concentration.

Apart from obtaining a concentrate with an obviously higher nutrient concentration than the original slurry, another objective is to obtain clean water as condensate.

Abstract:

Top of the line corrosion (TLC) is a serious concern in wet gas transportation pipelines operating in a stratified flow regime. Extensive research on TLC has been conducted in hydrocarbon-free environments while, in production environments, condensable hydrocarbons are always present. When water and hydrocarbons co-condense, the condensate comprises two immiscible liquids which have different wettability and corrosivity. In this study, the co-condensation process was investigated using a borescope for visual observation and a set of conductivity probes for quantification of water-wetted area.

OBJETIVO: determinar el efecto de una prueba aeróbica de natación en piscina clorada indoor sobre la concentración de NO2-, H2O2 y el pH en el condensado del aire espirado. MÉTODO: diez nadadores aficionados nadaron 2,5 km en piscina clorada. Se obtuvieron muestras antes y en cuatro oportunidades durante las ocho horas posteriores a la prueba. El análisis estadístico usó modelos mixtos y la prueba de Spearman RESULTADOS: la prueba se realizó a 74,99±10,10 % de la reserva cardíaca y duró 50,80±8,98 minutos. Posterior a la prueba disminuyó el NO2- (p=0,04) y el pH (p=0,02) en el condensado del a

Abstract:

Ammonia recovery from anaerobically digested cattle manure effluents through steam stripping was studied at a stripping tower temperature of 98–99 °C and a steam–water ratio approximately 56–72 g/L. The digested manure effluents were first treated by microfiltration and then the permeate was used as feed in steam stripping. The stripping performance was evaluated under different feed pH values, ammonia concentrations and temperatures. The increase of the initial feed pH does not significantly improve ammonia stripping efficiency due to the fact that the stripped effluent pH is increased during

Abstract:

The corrosion behaviour of a new titanium-based alloy, with nickel, molybdenum and zirconium as the main alloying elements, was studied in a simulated geothermal environment at various phase conditions of a corrosive fluid. Corrosion testing of carbon steel was also conducted for comparison. Both materials were tested at an elevated temperature between 180 and 350 °C and at a 10 bar gauge pressure in H2O containing HCl, H2S, and CO2 gases with an acidic condensate of pH = 3. The study found that the titanium alloy demonstrated good corrosion resistance in a single- and multiphase geothermal en

Abstract:

Mono Ethylene Glycol (MEG) is used primarily at low-temperature processing plant for extracting natural gas liquids. Typically a physical process plant comprises with gas dehydration system which allows for physical separation of water saturated gas by simple dew point depression and water condensation brought about by chilling from cross exchange with propane refrigerant. The resultant wet gas is prevented from freezing by injection of liquid desiccants to inhibit hydrate formation. The resulting dehydrated gas stream will have a dew point preciously equal to the saturated water volume of the

Abstract:

Abstract Gasification transforming organic compounds into energy-rich pyrolytic gas, is a climate-friendly treatment option for biological solid wastes. The condensates arising from the pyrolytic gas valorization is owing to high concentrations of small molecular phenols, cyanides, nitrogen-heterocyclics, aromatics and ammonium, posing an environmental and health hazard. In this paper, the watery phase of the biomass gasification condensate from spent mushroom compost (SMC), with a chemical oxygen demand (COD) of 16.4 g/L and total nitrogen of 2.3 g/L, was pretreated by Fenton oxidation.

Abstract:

The mobility of yeast chromosomes was analysed by two-dimensional pulsed-field gel electrophoresis. The first dimension was run at pH 8.0 in a 1% agarose gel. In the second dimension the electrophoresis conditions were identical, except that the pH was lowered and ethidium, spermine, or ionic detergents were added. Any mobility changes between the two dimensions could be identified as a deviation from the diagonal. At pH 6.0 the mobility of the chromosomes increases severalfold, whereas at pH 4.5 none of the chromosomes move into the agarose gel. The pH-induced mobility changes were reversed b
