This paper investigates the relationship between income growth and the trend in industrial wastewater discharge in China during the period 1981-2007. For the data encompassing all the provinces over the entire period considered, both an inverted U-shaped EKC and an N-shaped EKC are statistically significant. An analysis dividing provinces into rich and poor groups reveals that the EKC relations...

A two-patch discrete time plant-insect model coupled through insect dispersal is studied. The model is based on three different phases: Plant growth is followed by the dispersal of insects followed by insect attacks. Our objective is to understand how different intensities of dispersal impact both local and global population dynamics of the two-patch model. Special attention is paid to two situ...

Objective. To identify care-related and maternal risk factors for the antenatal nondetection of IUGR. Methods. In this hospital-based case-control study we compared antenatally undetected IUGR neonates (cases) to detected IUGR neonates (controls). Data were collected using newborn documentation sheets and standardized personal interviews with the mothers. We calculated antenatal detection rates...

Recent studies have shown that infants with intrauterine growth restriction (IUGR) undergo catch-up growth during infancy. The aim of our study was to evaluate the postnatal growth in a cohort of IUGR infants born in a tertiary-level Obstetric University Hospital of Northern Sardinia. An observational retrospective study was conducted on 12 IUGR (group A) and 12 control infants (group B) by mea...

We reviewed 13 children with partial growth plate arrest who had been treated by epiphyseolysis. Eight were followed to skeletal maturity and five for at least four years. In three cases the affected limb was restored to normal and in five the operation was successful in improving angular deformity and leg length discrepancy such that further surgery was not necessary. In the five failures, ang...

The simple fact that environmental resources are endowments is found to have profound effects on their patterns of allocation with changes in income, population, and income inequality. For broad classes of theoretical models, and in Pareto efficient as well as decentralized economies, environmental quality is found to follow a U-shaped pattern with rising income. We examine population changes a...

BACKGROUND Pregnancies with early onset fetal growth restriction have poor perinatal outcome. Sildenafil citrate (PDE -5 inhibitor) as a vasodilator increases utero-placental blood flow and potentiates fetal growth. CASE PRESENTATION In this study, a case was examined and Sildenafil was administered for her. It was found that Sildenafil improved the uterine blood flow with a favorable fetal o...

We study transitions between nonrenewable and renewable energy forms at di!erent development stages of an economy. It is shown that in the historical context the emphasis on energy production may evolve from renewables to nonrenewables and back to renewables. Typically both energy forms are used simultaneously. Along the equilibrium path, nonrenewable resource consumption may increase and their...
