Across western Europe and eastern North America, rates of acid deposition are falling in response to reductions in atmospheric S emissions (1, 2), and the water-quality of acidified surface waters is beginning to improve (1, 3). To aid in the management of S emissions, biogeochemical models designed to predict socalled “critical acid loads” (4), are now being used to predict the degree of water...

taking behaviors also affected early initiation of sex and that these associations varied somewhat between male and female adolescents.3 In this article, a followup to that analysis, we use more recent data for the young adult children of female NLSY respondents to more fully investigate early sexual activity. Additionally, we examine the correlates of ineffective contraceptive use and early ch...

Data on 550 healthy pregnant women, 550 healthy fathers and their healthy term neonates born from singleton pregnancies (37(+0) through 41(+6) week) during a one-year period were reviewed. Maternal mean age was 27.7 +/- 9.37 years, mean pregestational weight 64.0 +/- 9.50 kg, mean gestational weight gain 15.4 +/- 4.33 kg, mean height 169.7 +/- 5.81 cm, and mean gestational age 40.1 +/- 0.95 wee...

Cerebral malaria (CM) and severe malarial anemia (SMA) are 2 major causes of death in African children infected with Plasmodium falciparum. We investigated levels of naturally acquired antibody to conserved and variable regions of merozoite surface protein (MSP)-1 and MSP-2, apical membrane antigen (AMA)-1, and rhoptry-associated protein 1 in plasma samples from 126 children admitted to the hos...

In the last two centuries, age at menarche has decreased in several European populations, whereas adult height has increased. It is unclear whether these trends have ceased in recent years or how age at menarche and height are related in individuals. In this study, the authors first investigated trends in age at menarche and adult height among 286,205 women from nine European countries by compu...

In this article weight, height, and circum­ference of chest and head of 251 new-born and neotes who were seen in the Paed,iatric Dept. of Djorjani Hospital, Tehran, and the report of this invesUgwtion is as follow:  1. Weight-3.98% of new-born were under normal range, and 64.93% were normal, and 31.07% were above normal. 2. Height -9.56% of new-born were be-low, 84.45% were normal and 5.9...

The present study derives simple formulas for the prediction of optimal insertion length of an esophageal temperature-sensitive probe from the measurements of either standing or sitting height. The formulas assume that the optimal site for an esophageal temperature probe is in the region of the esophagus bounded by the left ventricle and aorta, corresponding to the level of the eighth and ninth...

In the present study, the fumes generated from manual metal arc (MMA) and submerged metal arc (SMA) welding of low temperature service steel, and the chromium and nickel percentages in these fumes, were measured at various horizontal distances and vertical heights from the arc in order to obtain a three dimensional distribution. The MMA welding fume concentrations were significantly higher than...

BACKGROUND Preeclampsia is associated with low birth weight, both because of increased risks of preterm and of small-for-gestational-age (SGA) births. Low birth weight is associated with accelerated childhood height gain and cardiovascular diseases later in life. The aim was to investigate if prenatal exposure to preeclampsia is associated with accelerated childhood height gain, also after adju...

Effects of breed and sward surface height on ewe liveweight and body condition changes and on lamb liveweight gains during grazing in the spring and autumn were studied. The output per hectare in each season was also calculated. A total of 112 Gallega ewes (35Æ6 kg live weight) and 204 Latxa ewes (47Æ5 kg live weight) with their lambs were used during the spring (March–June) to study the effect...
