The wear generation of double-heat-treated and as-cast large-diameter metal-on-metal (MOM) hip bearings was investigated using standard- and 'severe'-gait simulations. The test hypothesis was that double heat treatment would change MOM hip wear compared with the as-cast condition. Two groups of high-carbon MOM bearings of 40 mm diameter were manufactured and ...

The effect of temperature, O(2) and Mg(++) on the kinetic characteristics of the slow inactivation (fallover) of Rubisco isolated from spinach (Spinacia oleracea L.) was determined. Comparing 25 and 45 degrees C, the rate of activity decline of Rubisco increased by 20-fold, but the final ratio of steady state to ...

Evidence reported in an earlier paper suggests that infants introduced to indoor heated swimming pools in the first year of life show an association with spinal asymmetries including progressive adolescent idiopathic scoliosis (AIS) and in normal subjects vertical spinous process asymmetry. Indoor heated swimming pools may contain a risk factor ...

Maintaining fluid and heat balance is of vital importance to the newborn infant. At birth, the infant is exposed to a cold and dry environment, and preterm neonates in particular, are then at risk of dehydration and hypothermia. These conditions may have serious consequences and significantly influence mortality and morbidity. ...

We analysed the presence of nuclear bodies and particularly Cajal bodies during representative stages of gametophytic and haploid embryogenic development in isolated microspore and anther cultures of a model system (Brassica napus cv. Topas) and a recalcitrant species (Capsicum annuum L. var. Yolo Wonder B). The nuclear bodies domain is ...

The mole fractions of AgBr and Ag3Br3 in the saturated vapor at 840 K have been evaluated from the vapor mass spectrum, by comparison with the corresponding spectrum of AgCl vapor, where the monomer/trimer ratio is known accurately from vapor molecular weight measurements. Combination of these results with new measurements ...

We used graphic analysis and generalized additive modeling to assess whether mortality that is often attributed to ozone and sometimes to < 10-microm particulate matter (PM10) and sulfur dioxide in hot weather results from confounding by neglected weather factors. When mean daily air temperatures exceeded 18 degrees C, mortality at ...

The accretion of bodies in the asteroid belt was halted nearly 4.6 billion years ago by the gravitational influence of the newly formed giant planet Jupiter. The asteroid belt therefore preserves a record of both this earliest epoch of Solar System formation and variation of conditions within the solar nebula. ...

BACKGROUND: Mortality increases with hot weather, although the extent to which lives are shortened is rarely quantified. We compare the extent to which short-term mortality displacement can explain heat deaths in Delhi, São Paulo, and London given contrasting demographic and health profiles. METHODS: We examined time-series of daily mortality data ...

Infants with an aspirated foreign body who present with acute onset of obstructed airflow should be readily diagnosed. When aspirated foreign body is overlooked, patients may present with recurrent inspiratory, biphasic, or expiratory stridor. We report an infant who repeatedly presented with varying degrees of inspiratory stridor. The diagnosis of ...

Large-bodied species of hosts often harbor large-bodied parasites, a pattern known as Harrison's rule. Harrison's rule has been documented for a variety of animal parasites and herbivorous insects, yet the adaptive basis of the body-size correlation is poorly understood. We used phylogenetically independent methods to test for Harrison's rule across ...

OBJECTIVE: Preterm infants are prone to hypothermia immediately following birth. Among other factors, excessive evaporative heat loss and the relatively cool ambient temperature of the delivery room may be important contributors. Most infants <29 weeks gestation had temperatures <36.4 degrees C on admission to our neonatal unit (NICU). Therefore we ...

Tracheal agenesis, though seemingly rare and fatal to date, has been reported with increasing frequency. Establishment of the diagnosis necessitates a high index of suspicion in an infant in respiratory distress an birth, without a cry and in whom intubation is difficult. We report a case of tracheal agenesis.

A vegetation cover increase has been identified at global scales using satellite images and vegetation indices. This fact is usually explained by global climatic change processes such as CO(2) and temperature increases. Nevertheless, although these causes can be important, the role of socioeconomic transformations must be considered in some places, ...

Two euplanktonic ciliates, Urotricha psenneri n. sp. (Prostomatida) and Amphileptus piger (Vuxanovici, 1962) n. comb. (Pleurostomatida), were discovered in the surface plankton of the oligotrophic Lake Traunsee in Austria. Their morphology and infraciliature were studied in live cells as well as in specimens impregnated with protargol and silver nitrate. Urotricha ...

The degree of obliquity of the base of the first metatarsal is thought to predispose to metatarsus primus varus deformity. Radiographs currently are used to interpret the obliquity of the proximal first metatarsal but are subject to error. A 'normal' obliquity of the first metatarsal base has not yet been ...
