Prooxidative-Antioxidant Regulation in Patients with Serous Meningitis
Aktualʹnaâ Infektologiâ, 2016 Introduction. Serous meningitis takes a leading place among the central nervous system lesions, the share of which in neuroinfections structure ranges from 25 to 70 %. The imbalance in the functioning of prooxidant-antioxidant system plays a leading role

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 493-506, December 2022., 2022 Abstract Sustainable agriculture intensification is an urgent challenge in developing countries including Tanzania. One potential solution is to adopt farming systems that increase farm production by optimizing resource use efficiency, and integrated aquaculture system, which involves farming of fish and crops, is an example of such systems. This study

Nitrites Variation in Cheese depending on their Concentration in Milk
Scientific Papers Animal Science and Biotechnologies, 2023 In order to follow the modifications in time of milk nitrites quantity which are contained in cheese, we created the follwing experimental model. From the same known milk quantity with a known fat content we formed 4 milk control groups in which we added

Effect of pH and nitrite concentration on nitrite oxidation rate [PDF]
Bioresource Technology, 2011 The effect of pH and nitrite concentration on the activity of the nitrite oxidizing bacteria (NOB) in an activated sludge reactor has been determined by means of laboratory batch experiments based on respirometric techniques. The bacterial activity was measured at different pH and at different total nitrite concentrations (TNO₂).

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 540-551, December 2022., 2022 Abstract Feed effectors have been suggested to improve the efficiency of plant‐based shrimp diets by increasing attractability and palatability. This research trial aimed to expand upon previous Pacific white shrimp (Litopenaeus vannamei) research involving plant‐based diets, feed effectors and passive acoustic monitoring (PAM) in a laboratory setting ...

La production de nitrites lors de la dénitrification des eaux usées par biofiltration - Stratégie de contrôle et de réduction des concentrations résiduelles [PDF]
Revue des Sciences de l'Eau, 31(1), 2018, 61-73, 2017 The recent popularity of post-denitrification processes in the greater Paris area wastewater treatment plants has caused a resurgence of the presence of nitrite in the Seine river. Controlling the production of nitrite during the post-denitrification has thus become a major technical issue.

Isotopic constraints on lightning as a source of fixed nitrogen in Earth's early biosphere [PDF]
, 2023 Bioavailable nitrogen is thought to be a requirement for the origin and sustenance of life. Before the onset of biological nitrogen fixation, abiotic pathways to fix atmospheric N2 must have been prominent to provide bioavailable nitrogen to Earth's earliest ecosystems.

Photolysis of n-butyl nitrite and isoamyl nitrite at 355 nm: A time-resolved Fourier transform infrared emission spectroscopy and ab initio study [PDF]
J. Chem. Phys. 130, 174314 (2009), 2009 We report on the photodissociation dynamics study of n-butyl nitrite (n-C_4H_9ONO) and isoamyl nitrite ((CH_3)_2C_3H_5ONO) by means of time-resolved Fourier transform infrared (TR-FTIR) emission spectroscopy. The obtained TR-FTIR emission spectra of the nascent NO fragments produced in the 355-nm laser photolysis of the two alkyl nitrite species showed
