Abstract Background In this research, the effects of exogenous application certain biostimulants [amino acid (AA), humic (HA), fulvic (FA), and seaweed extract (SE)] on fruit yield quality, leaf mineral contents, some critical physio-chemical characteristics grapevine ( Vitis vinifera L.) cv. ‘Yaghouti’ were investigated under well-watered (WW) drought-stressed (DS) conditions. Results Drought ...

The state of ripeness at harvest is a key piece information for growers as it determines the market price yield. This has been traditionally assessed by destructive chemical methods, which lead to low-spatiotemporal resolution in monitorization crop development and poor responsiveness growers. These limitations have shifted focus remote-sensing, spectroscopy-based approaches. However, most rese...

We herein report on the effect that water molecules, present as impurities, in the vicinity of an ionic liquid model structure, may induce on the Lewis acidity/basicity patterns normally observed in these materials. Depending on the position and orientation of water, the Lewis acidity/basicity pattern changes from "normal distribution" (i.e., the basicity located at the anion moiety and the aci...

In a series of 59 experiments in nine duodenal ulcer patients, 24 hour intragastric acidity was measured before, during, and after treatment with daily oral omeprazole. Omeprazole 10, 20, and 30 mg/day for one week caused a 37, 90, and 97% decrease of 24 hour intragastric acidity, respectively. No further decrease of acidity was observed when the dose of omeprazole was doubled to 60 mg/day, or ...

The pH, alkalinity, and acidity of mine drainage and associated waters can be misinterpreted because of the chemical instability of samples and possible misunderstandings of standard analytical method results. Synthetic and field samples of mine drainage having various initial pH values and concentrations of dissolved metals and alkalinity were titrated by several methods, and the results were ...

statement of problem: one of the factors in dental erosion is consumption of acidic soft drinks. although the effects of various additives to acidic soft drinks for the prevention of tooth erosion have been assessed, little data have been published on the possibility of preventing the erosion through soft drinks containing calcium-carbonate nanoparticles.  objectives: to examine the erosive fac...

The effect of Methanolic, chloroform and diethel ether extracts of Mimosa pudica was investigated in rats to evaluate the anti-ulcer activity by using three models, i.e. Aspirin, Alcohol and pyloric ligation models experimentally induced gastric ulcer. The parameters taken to assess anti-ulcer activity were volume of gastric secretion, PH, free acidity, total acidity and ulcer index. The result...
