Streptococcus bovis JB1 cells energized with glucose transported glutamine at a rate of 7 nmol/mg of protein per min at a pH of 5.0 to 7.5; sodium had little effect on the transport rate. Because valinomycin-treated cells loaded with K and diluted into Na (pH 6.5) to create an artificial delta psi took up little glutamine, it appeared that transport was driven by phosphate-bond energy rather th...

As the interest in hydrogen to help decarbonization of transport sector is growing fast, new methods for its storage a key point improve diffusion many contexts, investigating innovative methods. Ammonia promising solution, as content per volume unit higher than stored liquid form; furthermore, ammonia does not require cryogenic temperature nor high amounts energy liquefaction. In this study, t...

A 41-year-old woman was diagnosed with bipolar disorder at 31. After a thyroidectomy at 33 years old, she was found to have subclinical hypothyroidism: the thyroid-stimulating hormone (TSH) was 6.196 uIU/ml (reference range: 0.34-5.60) and free thyroxine (FT4) was 0.46 ng/dl (reference range: 0.54-1.40). No intervention was given due to her refusal. She started to participate in the day-care un...

Ammonia has great prospects in the context of transition to carbon-free energy. It can be used as fuel gas turbines, cells, internal combustion engines, and burned together with coal. However, industrial production ammonia is based on Haber-Bosh process, which involves use natural coal, which, this case, does not make it really carbon-free. This study proposes a method produce ammonia, environm...

Intensive swine farming causes strong local environmental impacts by generating effluents rich in solids, organic matter, nitrogen, phosphorus, and pathogenic bacteria. Insufficient treatment of hog farm has been reported for common technologies, vermifiltration is considered a promising alternative that, however, requires additional processes to remove nitrate phosphorus. This work aimed study...

Gas-driven sorption heat pumps (GDSHPs) exhibit possibilities in the reduction of energy use and environmental impact of heating systems that utilise natural gas. By utilising renewable thermal energy from the environment, that is, air, ground or water sources, significant reduction of primary energy use can be achieved. However, high cost, low coefficient of performance (COP) and large volume ...

Biotreatment of various ratios of H2S and NH3 gas mixtures was studied using the biofilters, packed with co-immobilized cells (Arthrobacter oxydans CH8 for NH3 and Pseudomonas putida CH11 for H2S). Extensive tests to determine removal characteristics, removal efficiency, removal kinetics, and pressure drops of the biofilters were performed. To estimate the largest allowable inlet concentration,...

Several anthropogenic interventions, common in agriculture, may influence active bacterial communities in soil without affecting their total composition. Therefore, the composition of an active bacterial community in soil may reflect its relation to biogeochemical processes. This issue was addressed during two consecutive years in olive-orchard soil, irrigated with treated wastewater (TWW) in a...

Unused nitrogen in the manure in the form of uric acid has contributed immensely to ammonia emissions. However, diet manipulation and management (an ideal dietary crude protein) as well as litter treatment with acidifiers and manure removal have been recognized as a means to reduce ammonia emissions from poultry operations. This study was an assessment of the nutrient profile accumulated laying...
