Stress and its associated factors in mothers with preterm infants in a private tertiary care hospital of Karachi, Pakistan: an analytical cross-sectional study.

Objectives: This goal of this research is to present a comprehensive method for evaluating stress and the factors that contribute to it in mothers of premature babies.

Design: Analytical cross-sectional study.

Setting: Data were collected from inpatient service for preterm infants including neonatal intensive care unit, and neonatal step-down units of the Aga Khan University Hospital-a private tertiary care hospital in Karachi, Pakistan.

Numerical Modeling of Recovery of Moisture from the Unsaturated Zone: A Feasibility Study.

Numerical modeling of the recovery of moisture by injecting warm air in the unsaturated zone in a 100 m × 100 m plot of agricultural land in Kuwait, a country located in an arid environment, was conducted to provide "proof of concept" of the technique. If technically and economically feasible, it will be a potential additional source of water that could be exploited for farming activities and other uses. The COMSOL software was used to develop the model and, based on the results of the scenario runs, the effects of different hydraulic and operational parameters, including that of well spacing, on moisture recovery were assessed.

A numerical modelling approach to investigate the fate of brine reject of farm scale desalination plants on groundwater aquifers in arid environments.

Farm-scale desalination units are gaining popularity for agricultural irrigation in arid countries, such as Kuwait to meet freshwater demands. However, less attention has been given to the management of environmentally hazardous brine reject water they produce. In this study we investigated the fate of brine water produced by the inland desalination units on the underlying aquifers using numerical modelling and field investigations.
