In the present study, we have made an attempt to prepare complexed PVA-PVP-KNO3-BaTiO3 blend composite polymer electrolyte membranes composed of potassium nitrate (KNO3) as salt and BaTiO3 of various concentrations as filler and studied their properties. The advantages of addition the fillers are the increase in ionic conductivity at room temperatures and the improvement of the stability at the interface with electrodes.

A portable and simple Raman scattering and photoluminescence spectroscopy system was set up for sensitive and rapid determination of nitrate/nitrite at low concentrations in water samples. The SERS (Surface Enhanced Raman Scattering) e active Ag/ITO substrates were prepared and employed to obtain the enhanced Raman scattering light from the sample.

In this work, Ag nanoparticles (NPs) were fabricated by the solvothermal method of silver nitrate in different organic solvents with the presence of sodium oleate (SOA) and 1- octadecanol (OCD-ol). The effects of different solvents and concentrations of OCD-ol on the morphology and properties of the Ag nanomaterials were investigated in detail.

Municipal wastewater treatment plants generally utilise biological activated sludge processes to remove organic compounds and nitrogen. The biological nitrogen removal (BNR) occurs in two steps, nitrification (ammonium removal) and denitrification (nitrates removal). This study focused on a medium-sized wastewater treatment plant (WTP) which experienced poor nitrification for years, mainly when the weather temperature drops.

Vegetables are the major source of dietary Nitrate that have a range of variations in Nitrate. The presence of Nitrate in vegetables is often associated with harmful effects on human health. The study investigated Nitrate intake of vegetables in Phu My ward, Hiep An ward, and Tuong Binh Hiep ward in Thu Dau Mot city by UV-VIS Molecular Absorption Spectrometer to determine of Nitrate concentration with measurement wavelength of 410 nm.

In this work, the preparation of 2,4,6-trinitroresorcinol by the sulfonation-nitration method of resorcinol through three stages was investigated. The results showed that the 2,4,6- trinitroresorcinol synthesis efficiency reached the highest value (82-83%) when the molar ratio of HNO3/resorcinol was 3.45/1, the temperature of the nitrate stage was 30-70 ºC, and the concentration of HNO3 solution was 72%.

The nutrient pollution index showed moderate to very high pollution while the waterbodies will pose very high non-carcinogenic health risks to users via the oral pathway. Overall, the waterbodies are at risk of eutrophication and efforts should be put in place to reduce anthropogenic activities around the area and thus input of nutrients in these water bodies.

In this study, silver nanoparticle (AgNP) synthesis was carried out using Onosma sericeum Willd. aqueous extract for the first time, with a simple, economical, and green method without the need for any other organic solvent or external reducing or stabilizing agent. A variety of AgNPs, all of different particle sizes, were synthesized by controlling the silver ion concentration, extract volume, temperature, and pH. It was determined that the optimum conditions for AgNP synthesis were 1 mM AgNO3 , pH 8, 25 °C, 20 g/200 mL extract, silver nitrate, and extract ratio 5:1 (v/v).

MADS-box transcription factors (TFs) are the key regulators of multiple developmental processes in plants; among them, a chrysanthemum MADS-box TF CmANR1 has been isolated and described as functioning in root development in response to high nitrate concentration signals. However, how CmANR1 affects root and shoot development remains unclear.

In addition, the Pb levels in the leafy vegetables were not correlated with nitrate concentration. Based on the results of our investigation, the approximate daily intake (DI) of NO3 – , NO2 – and Provisional Tolerable Weekly Intake (PTWI) of lead were assessed to human health in consuming the observed leafy vegetables.

In points of annual crop farming and close to residential the contribution of inorganic fertilizers to the total concentration of nitrate was estimated, based on the δ 15N-NO3 values, to be as high as more than 60% and the contribution of water waste was around 35-40%. This is the first time isotopic signature of nitrogen-15 in nitrate (δ15N-NO3) was applied as a tool to assess and identify sources of the nutrient in aquatic environment.

The results of the study revealed thaturea was most effective in inhibiting the fungal growth at all the tested concentration. It was also found that soluble NPK and Potassium nitrate promoted the fungal growth at all the concentration. Among biorationals, bromonitropropanol gave the highest mycelial inhibition (73.72%), while sodium and potassium bicarbonates at lower concentration promoted the fungal growth, but inhibited the growth at higher concentration.

This research has analyzed, evaluated ground water salinity in Hau Loc district, Thanh Hoa province by determining the concentration Chloride-Silver nitrate titration with Chromate indicator (MO Method) and establishing a zoning map of salinity. The results showed the groundwater at researched areas was being saline over the allowable standards many times. The highest salinity concentration of Cl- exceeded 15 times the allowable standards. This study consequently proposed some solutions for efficient using of water and reducing the groundwater salinity level in the region.

The uptake rate of nitrate by leaves and roots was simultaneously investigated in the seagrass T. hemprichii collected from Lo river, Nha Trang. The principle of nutrient uptake of seagrass was based on the approaches of the Michaelis-Menten model. The laboratory experiments of nitrate uptake were done the ranges of ambient nitrate concentrations in the separate water column of leaves and roots. The calculated results indicated that the nitrate uptake rate through the leaves was higher than that of the roots.

Silver nano particles were synthesized using two potential isolates of Trichoderma, Psudomonas fluorescens and one isolate of pathogen Rhizoctonia solani cell free culture filtrates incubated at different days 0, 5, 10 and 15. The present investigation revealed that bionano preparations irrespective of the isolate source used, i.e., Trichoderma, P. fluorescens or R. solani were found better in decreasing the sheath blight incidence in vitro though variation existed in terms of quantum of disease reduction.

Present investigation was carried out in the rainout shelter at Student Instructional Farm (SIF), Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) during Kharif (wet season) 2015 and 2016. Experiments were laid out in randomized block design with 3 replications, one variety i.e. Swarna Sub 1and nine foliar treatments. Rice plants were exposed to drought at 60 DAT for 15 days by holding irrigation during drought treatment. During drought treatment soil moisture tension of the field was ranged from 60-80 kPa.
