Integrated evaluation of groundwater hydrochemistry using multivariate statistics and irrigation-based water quality indices.

This research evaluates the appropriateness of groundwater for potable and irrigation need in the Mathura District of Uttar Pradesh, India. Fifteen different hydro chemical parameters selected for analysis, they are pH, total dissolved solids (TDS), electrical conductivity (EC), Total Hardness (TH), Mg, Cl, Ca, Na, K, NO, SO, PO, F, CO, and HCO In the present research various approaches such as Multivariate statistical techniques (MSTs), Arithmetic water quality index (WQI), sodium absorption ratio (SAR), permeability index (PI), sodium percentage (Na%), US salinity, were examined. The WQI assessment reveals that 65% poor quality, 5% very poor quality and 15% water is not suitable for drinking purpose category.

Technical Considerations, Applications, and Benefits of Organogels in Topical Drug Delivery Systems.

Organogels represent semi-solid systems where an organic liquid phase is entrapped within a three-dimensional network formed by self-assembled, crosslinked, or entangled gelator fibers. These versatile materials find applications in a wide range of fields, including chemistry, pharmaceuticals, cosmetics, biotechnology, and food technology. Notably, in pharmacology, they serve as valuable platforms for drug and vaccine delivery, facilitating the transport of active ingredients through various routes such as transdermal, oral, and parenteral.

Comparative evaluation of modified crater (endonucleation) chop and conventional crater chop techniques during phacoemulsification of hard nuclear cataracts: A randomized study.

Purpose: To compare the clinical outcomes of endonucleation chop (EC) versus conventional crater (CC) chop techniques in phacoemulsification of hard nuclear cataracts.

Methods: In this Prospective, longitudinal, randomized controlled study with double-blinding. Hundred consecutive eyes with uncomplicated cataracts (nucleus grades 3 and 4) were equally divided into Group A (EC) and Group B (CC).

Surface-induced morphology and free-energy pathways in breakup of a nematic liquid crystalline cylinder.

We compute the surface-induced morphology and the free-energy pathways as a cylindrical liquid crystalline filament with preferred homeotropic (orthogonal) interface orientation passes through a sequence of growing sinusoidal perturbations and breaks up into droplets. Liquid crystalline morphology is determined using a simulated annealing algorithm [R. K.

Orientational multiplicity and transitions in liquid crystalline droplets.

Orientation distributions in droplets of liquid crystals with homeotropic anchoring are computed with a simulated annealing algorithm that minimizes the free energy of the Oseen-Frank continuum theory. The droplets exhibit multiple orientational steady states that are separated by finite energy barriers over the entire range of the dimensionless ratio of surface to elastic forces, with maximum transition energy densities of the order of 2000 J/m3 (Pa) for a typical liquid crystalline droplet with a spherical radius of 1 microm. The transition energy densities decrease with elongation to spheroidal droplets with aspect ratios of four or more, indicating that droplet elongation is favored to drive surface-induced transitions.

Power-law and exponential segregation in two-dimensional silos of granular mixtures.

When a binary mixture of granular materials, differing in shape or size, is poured into a quasi-two-dimensional silo, segregation of the mixture is observed. Depending on the size ratio d2/d1 of the species, the mixture segregates completely or partially into the pure species. To study the partial-segregation effect we propose a theoretical model based on the work of Boutreux and de Gennes [J.
