Octachloronaphthalene (OCN), a serious environmental pollutant, has been investigated by charge density analysis to unravel several unexplored factors responsible for steric overcrowding. The topological features of the enigmatic peri interactions contributing to steric overcrowding are qualified and quantified from experimental and theoretical charge-density studies. A new facet in the fundame...

Wireless sensor technologies can be used by intelligent transportation systems to provide innovative services that lead to improvements in road safety and congestion, increasing end-user satisfaction. In this article, we address vehicle routing with backup provisioning, where the possibility of reacting to overloading/overcrowding of vehicles at certain stops is considered. This is based on the...

Main results 10.3% of participants were depressed at follow up. Multiple disadvantages in early life were associated with depression (odds ratio [OR] 5.1, 95% CI 2.1 to 12.0). More women than men had depression (OR 2.7, CI 1.1 to 6.3). Types of disadvantages that were associated with depression were social dependence and overcrowding (OR 5.1, CI 2.1 to 12.0), poor physical care and poor motheri...

A survey of AFDC recipients in California shows that income, even when adjusted for household need and augmented by the food stamp grant, poorly predicts hunger or overcrowding among respondents. Families with teenage boys report hunger much more often than their incomes would predict, as do families whose finances have recently deteriorated. Families seem to cut back on food consumption before...

Nursing care is arguably the single biggest factor in both the cost of hospital care and patient satisfaction. Inadequate inpatient nursing levels have also been cited as a significant factor in medical errors and emergency room overcrowding. Yet, there is widespread dissatisfaction with the current methods of determining nurse staffing levels, including the most common one of using minimum nur...

Sudden catastrophic events like fires, hurricanes, tsunamis, landslides and deforestation increase population densities in habitat fragments, as fleeing animals encroach into these refuges. Such sudden overcrowding will trigger transient fluctuations in population size in the refuges, which may expose refuge populations to an increased risk of extinction. Until recently, detailed information ab...

In a search for aetiological processes which might explain the association of stomach cancer with poverty, we have related mortality from the disease in the local authority areas of England and Wales during 1968-78 to indices of living standards derived from the 1971, 1951 and 1931 censuses. We have also analysed recently released data from a national survey of overcrowding carried out in 1936....

Objective: Standardization of hospital emergency units is a major goal in developed countries to decrease the duration of patients stay in these units. The present study was undertaken to evaluate the prevalence of long-term staying in an emergency ward. Methods: In the present 2-month cross-sectional study, patients referring to the emergency ward of Imam Hos...
