Water hydration in cutinized cell walls: a physico-chemical analysis.
Water sorption by plant cuticular membrane isolates, mainly identified as polysaccharides, after selective extraction of the lipid components waxes and cutin was measured over the whole range of water activity. From water sorption isotherm, the strengths of water binding and water clustering were estimated. Data obtained by differential scanning calorimetry and Fourier-transform and near infrar...
متن کاملAssessment of Birjand flood plain water quality by physico-chemical parameters analysis in Iran
We assessed the physico-chemical status of twelve surface water samples from the Birjand flood plain (east of Iran) during fall 2010. The sampling points were selected on the basis of their importance. The physico-chemical parameters such as pH, temperature (T), electrical conductivity (EC), total dissolved solids (TDS), total hardness (TH), calcium (Ca2+), magnesium (Mg2+ ), sodium (Na+), pota...
متن کاملInstantaneous physico-chemical analysis of suspension-based nanomaterials
High-throughput manufacturing of nanomaterial-based products demands robust online characterization and quality control tools capable of continuously probing the in-suspension state. But existing analytical techniques are challenging to deploy in production settings because they are primarily geared toward small-batch ex-situ operation in research laboratory environments. Here we introduce an a...
متن کاملAnalysis of physico-chemical parameters, genotoxicity and oxidative stress
In India, agricultural soil has been deteriorated by various on-going practices involving application of chemical fertilizers, pesticides and effluents. Presently, Amritsar (Punjab), an agricultural land, is undergoing rigorous cultivation of wheat and rice crops which consequently increased the application of chemical pesticides and fertilizers for high yield. These agricultural practices are ...
متن کاملQuantitative physico-chemical analysis of the acidosis of cardiac arrest
Metabolic acidosis is a common finding after cardiac arrest. Until recently this acidosis was mainly attributed to lactate. The physico-chemical approach to acid-base balance permits the detection of previously unmeasured ions. These ions have been shown to affect the acid-base status of patients.
