Understanding of any age-related differences in distortion product otoacoustic emissions (DPOAEs) during infancy is important for the use of DPOAEs in detection of cochlear impairment in infants. We studied DPOAEs at 10 frequencies of f2 primary tone between 500 Hz to 10 kHz longitudinally during the first year of life ...

The effects of Karenia brevis (Gymnodiniales, Gymnodiniaceae) on the feeding activity of juveniles of four species of bivalve mollusc were examined in the laboratory to assess the potential impacts on these important shellfish populations from Florida. Clearance rates were determined under short-term (one hour) static and long-term (two days) flow-through ...

The recently formulated metabolic theory of ecology has profound implications for the evolution of life histories. Metabolic rate constrains the scaling of production with body mass, so that larger organisms have lower rates of production on a mass-specific basis than smaller ones. Here, we explore the implications of this constraint ...

Production parameters were determined for kidding, offtake and mortality rates, and milk production and composition of Angora goats in two communal agro-ecological zones, Mountains and Lowlands, of Molimo-nthuse area in Lesotho. True incidence rates and risk rates as used in dynamic populations were used to calculate the different production parameters. ...

PURPOSE: Cryptorchidism is the most common genital anomaly identified at birth, and endocrine disrupters in the environment may be causing an increase in this entity. To determine whether the rate of surgery for undescended testes is increasing, we evaluated all documented orchiopexies performed in New York State during a 19-year ...

This ecological study aimed to identify possible reasons for higher pertussis hospitalization rates in indigenous Australian infants. Two national datasets were analysed: the Hospital Morbidity Database and the Australian Childhood Immunisation Register (ACIR). Most (52%) pertussis hospitalizations in indigenous infants occurred at 0-2 months of age, and rates in these ...

The author of a recent book inferred that the slowed decline in U.S. vehicle fatality rates in the 1990 s relative to other industrialized countries resulted from too much emphasis on vehicle factors. He claimed that Canada had the same vehicle mix but a lower fatality rate. Actually, U.S. death ...

Both the rate and causes of twentieth century global sea-level rise (GSLR) have been controversial. Estimates from tide-gauges range from less than one, to more than two millimetre yr(-1). In contrast, values based on the processes mostly responsible for GSLR-mass increase (from mountain glaciers and the great high latitude ice ...
サナンマン・エレノア, M.
The infant mortality rate was 3.8% in Japan and 6.8% in the United States in 1999. Even though the maternal death rate per 100,000 people is 7.1% in both Japan and the U.S., how does Japan have such a low infant mortality rate? This paper will present a general understanding ...

Most theoretical studies on character displacement and the coexistence of competing species have focused attention on the evolution of competitive traits driven by inter-specific competition. We investigated the evolution of the maturation rate which is not directly related to competition and trades off with the birth rate and how it ...

BACKGROUND AND OBJECTIVE: Automated database studies have become a cornerstone of drug safety assessment. To assess the reliability of automated data, we compared the hospitalisation and mortality rates among three similar studies of automated healthcare databases in North America.

This article shows trends in injury and poisoning mortality in England and Wales using a matrix of mechanism (e.g. fall, fire) by intent (e.g. accident, suicide) developed by the International Collaborative Effort (ICE) on injury statistics. Overall injury and poisoning mortality rates have declined for both males and females. Declines ...

A brief analysis of the known data on the potential danger of radiocarbon incorporation into DNA structure shows that the great genetic importance of transmutational transformations of DNA-incorporated 14C is theoretically and experimentally proved. This effect exists both in huge and small radiation doses (similar to doses of 14C natural ...

A new study by Jeffreys et al. shows that the rate of recombination in recombination hotspots in humans is not constant through time. This observation adds weight to the idea that hotspots are transient on evolutionary timescales. However, questions remain as to what controls their evolution and how these rapid ...

This paper tests the proposal that chimpanzees (Pan troglodytes) and humans have similar rates of death from intraspecific aggression, whereas chimpanzees have higher rates of non-lethal physical attack (Boehm 1999, Hierarchy in the forest: the evolution of egalitarian behavior. Harvard University Press). First, we assembled data on lethal aggression from ...

We examined the association between month of birth and completed suicides among major league baseball players (N = 76). More than twice as many players born in August committed suicide (N = 19) than any other birth month. This association was statistically significant when birth month was corrected for differences ...

Rural suicide rates have been shown to be disproportionately high in several countries. This study compares suicide rates in Cornwall with the rest of England and Wales over a 90-year period (1911-2001). Age and sex standardised mortality ratios were calculated for suicide and undetermined death for Cornwall standardised to England ...

Between 1990 and 2002, the age pattern of Type I first-birth rates (i.e., the hazard of a first birth) among U.S. women was bimodal. This pattern, driven by changing differential fertility patterns among racial and ethnic groups, reached its apex at the mid-1990s and had almost vanished by the decade's ...

Product branching ratios and thermal rate coefficients for the dissociative recombination of C3D(+)7 and C4D(+)9 have been measured in the ion storage ring CRYRING. The results for C3D(+)7 are believed to be slightly more accurate than those obtained earlier for C3H(+)7. Only the C-C bond breaking channels could be measured ...
