STUDY OF STABLE NITROGEN FORMS IN NATURAL SURFACE WATERS IN THE PRESENCE OF MINERAL SUBSTRATES

The influence of substrates on the oxidation of reduced toxic forms of nitrogen in river water was investigated by laboratory modelling. Granite and expended clay accelerate the oxidation of ammonium and nitrite ions from 2 to 4 times. The presence of calcium carbonate in water hinders the oxidation of nitrogen in the polluted water

UPDATING THE STATISTICAL REGISTER OF HOUSING IN THE REPUBLIC OF MOLDOVA USING OPEN-SOURCE GIS TECHNOLOGIES

This article describes the possibilities of promoting and implementing open-source geoinformation technologies in the field of statistical activity in the Republic of Moldova, which will simplify and streamline the process of analysis, collection, systematization of data, as well as their dissemination. Since 2019, the National Bureau of Statistics of the Republic of Moldova, according to the recommendations of the United Nations, has proposed the creation of the geo-coded Statistical Register of Housing (SRH). With the creation of the National Spatial Data Infrastructure (NSDI), this goal can be achieved, as SRH will form the basis of the Population and Housing Census (PHC) from the 2020 round. The geospatial data from SRH will be used to delimit the census enumeration areas, and the reviewed population will be attached to the geographical coordinates of the dwelling. These enumeration areas will cover the entire territory of the Republic of Moldova and will serve to plan human resources, organize field activities and ensure the full coverage of census units (for people, households and dwellings)

Neurological Manifestations of SARS-CoV2 Infection: A Narrative Review

The COVID-19 virus frequently causes neurological complications. These have been described in various forms in adults and children. Headache, seizures, coma, and encephalitis are some of the manifestations of SARS-CoV-2-induced neurological impairment. Recent publications have revealed important aspects of viral pathophysiology and its involvement in nervous-system impairment in humans. We evaluated the latest literature describing the relationship between COVID-19 infection and the central nervous system. We searched three databases for observational and interventional studies in adults published between December 2019 and September 2022. We discussed in narrative form the neurological impairment associated with COVID-19, including clinical signs and symptoms, imaging abnormalities, and the pathophysiology of SARS-CoV2-induced neurological damage

Enhanced adsorption of orthophosphate and copper onto hydrochar derived from sewage sludge by KOH activation

Hydrochar, produced by hydrothermal carbonization of sewage sludge, adsorbs orthophosphate to improve effluent quality, recover &amp; reutilize phosphorous and positively impact sewage sludge management.</p
