Comparing Large-Eddy Simulation and Gaussian Plume Model to Sensor Measurements of an Urban Smoke Plume

The fast prediction of the extent and impact of accidental air pollution releases is important to enable a quick and informed response, especially in cities. Despite this importance, only a small number of case studies are available studyin...

Gut Microbial Nitrate Reduction to Ammonia: A Possible Pathway of Biological Nitrogen Provisioning in Freshwater Insects.

Integrated Ecotoxicological Assessment of Metal Nitrates in Lemna minor Based on Growth Inhibition, Biochemical Responses, and Species Sensitivity Comparison.

Analysis of groundwater and surface water quality using modelled water index and multivariate statistics in Kampala and Mbarara Districts, Uganda

Abstract The demand for domestic, public and industrial use of water increases with population growth. However, activities from humans and natural environment have resulted into decline in water quality. The aim of this study was to evaluat...

Modulation of Mode‐Water Eddies on Upper Ocean Responses to Tropical Cyclones

Abstract The modulation of anticyclonic subsurface‐intensified mode‐water eddies (MWEs) on the oceanic physical and biological responses to tropical cyclones (TCs) is investigated using satellite measurements, in situ observations and numer...

Uranyl Nitrates: By-Products of the Synthetic Experiments or Key Indicators of the Reaction Progress?

Six novel uranyl nitrate compounds K3[(UO2)(NO3)Cl3](NO3) (1, 2), α-Cs2[(UO2)(NO3)Cl3] (3), [(UO2)(NO3)2(H2O)2][(CH3NH3)2(NO3)2] (4), Cs2[(UO2)(NO3)4] (5), and [(UO2)2(OH)2(NO3)2(H2O)3](H2O) (6) have been prepared from aqueous solutions. Th...

1,1-Dimethylbiguanidium(2+) dinitrate

In the crystal structure of the title compound, C4H13N52+·2NO3−, the main intermolecular interactions are the N—H...O hydrogen bonds between the cationic amino groups and the O atoms of the nitrate ions. All ami...

Glass-fiber catalysts for selective catalytic reduction of nitrogen oxides by CO and hydrocarbons

Glass-fiber catalysts (GFCs) are investigated in the process of the catalytic reduction of nitrogen oxides by hydrocarbons and carbon monoxide contained in waste and flue gases. Studies show that the platinum-based GFCs prepared by surface ...

Reusing Effluent Water in Drainage Ditches for Irrigation in Hilly Regions

【Objective】 Most hilly regions in China are short of freshwater resources and recycling the effluent water in their drainage ditches is a way to relieve this pressure and improve water use efficiency. This paper investigates how reusing the...

Operation strategies of n-DAMO and Anammox process based on microbial interactions for high rate nitrogen removal from landfill leachate

Nitrate/nitrite-dependent anaerobic methane oxidation (n-DAMO) coupling to Anaerobic ammonium oxidation (Anammox) provides an opportunity for simultaneous nitrogen removal and methane emissions mitigation from wastewater. However, to achiev...

Critical review of leachate pathways, groundwater contamination, and health risks in tropical urban aquifers

Abstract Rapid, under-serviced urbanization across the tropical belt has left many cities dependent on open dumps. These dumps and poorly engineered landfills often sit above shallow, heavily used aquifers. This review uses the Doddabidarak...

OsAAI1 is dependent on the nitrate pathway toregulate rice root development in response to high salt stress

Salt stress limits plant growth and yield. Though nitrogen fertilizer can alleviate salt damage, the effects of salt and nitrate on the stress resistance gene OsAAI1 are unclear. This study examined the Salt stress sensitivity of OsAAI1 tra...

DESENVOLVIMENTO INICIAL DO MILHO PIPOCA CULTIVADO SOB DIFERENTES RELAÇÕES NH4 +:NO3-

The culture of the popcorn comes as a promising culture for region of the Brazilian northeast, however they are still scarce studies to make possible the expansion of this culture, especially as the fertilization. This experiment was accomp...

Comparative Evaluation of the Antioxidant and Immunomodulatory Activities of Carrot (<i>Daucus carota</i> L.) Aerial Parts and Roots Using Different Extraction Methods

Carrot (Daucus carota L.) is a widely consumed root vegetable, yet its aerial parts, including leaves and stems, are typically discarded as agricultural by-products, despite their potential biological value. This study comparatively evaluat...

Microbial and biogeochemical responses to projected future nitrate enrichment in the California upwelling system

Coastal California is a dynamic upwelling region where nitrogen (N) and iron (Fe) can both limit productivity and influence biogeochemistry over different spatial and temporal scales. With global change, the flux of nitrate from upwelling i...

Survival and growth of fish (Lates calcarifer) under integrated mangrove-aquaculture and open-aquaculture systems

The potential use of mangrove swamp for fish farming industry is not clearly known. Therefore, current study was conducted to assess the growth performance of the Asian Seabass, Lates calcarifer cultivated in integrated mangrove-aquaculture...

Sources of Contaminants of Emerging Concern in Groundwater of Barcelona Urban Area

Groundwater is a vital resource for the development of urban areas, where the problem focuses on the quantity and on the quality of this freshwater resource. Barcelona is a good example as because currently groundwater is used for irrigatio...

Soil Geochemical Properties Influencing the Diversity of Bacteria and Archaea in Soils of the Kitezh Lake Area, Antarctica

It is believed that polar regions are influenced by global warming more significantly, and because polar regions are less affected by human activities, they have certain reference values for future predictions. This study aimed to investiga...

Effects of long-term exposure to air pollutant mixture on blood pressure in typical areas of North China
