The Relationship

Widespread occurrence in cotton of 'parrot beaked' bolls, with one or more locule empty of seed, was shown to be related to periods when anthesis takes place under conditions of high temperature and water stress. Marked sowing date effects were recorded ; cotton sown in March and April having significantly lower percentage of parrot beaked bolls than cotton sown in December. Significant varietal differences in amount of the phenomenon were also recorded. The relationship between anther contabescence, and subsequent development of the parrot beaked condition, was clearly shown, and the effects of parrot beaked bolls on yield is discussed. Limited tests of lint quality showed no difference between lint from normal and parrot beaked bolls.

The Relationship

This chapter chronicles the relationship between African religious practices on the continent and African American religion in the plantation Americas in the era of slavery and the transatlantic slave trade. A new generation of scholars who emerged in the 1960s and 1970s have demonstrated not only that African religious practices exhibit remarkable subtlety and complexity but also that these cultures have played significant roles in the subsequent development of religious practices throughout the world. Christianity, Islam, and traditional African religion comprised a set of broad and varied religious practices that contributed to the development of creative, subtle, and complex belief systems that circulated around the African Diaspora. In addition, this chapter addresses some of the vexed epistemological challenges related to discussing and describing non-Western ritual and religious practices.

Abstract Background Although exposure to air pollution has been linked to many health issues, few studies have quantified the modification effect of temperature on the relationship between air pollutants and daily incidence of influenza in Ningbo, China. Methods The data of daily incidence of influenza and the relevant meteorological data and air pollution data in Ningbo from 2014 to 2017 were retrieved. Low, medium and high temperature layers were stratified by the daily mean temperature with 25th and 75th percentiles. The potential modification effect of temperature on the relationship between air pollutants and daily incidence of influenza in Ningbo was investigated through analyzing the effects of air pollutants stratified by temperature stratum using distributed lag non-linear model (DLNM). Stratified analysis by sex and age were also conducted. Results Overall, a 10 μg/m3 increment of O3, PM2.5, PM10 and NO2 could increase the incidence risk of influenza with the cumulative relative risk of 1.028 (95% CI 1.007, 1.050), 1.061 (95% CI 1.004, 1.122), 1.043 (95% CI 1.003, 1.085), and 1.118 (95% CI 1.028, 1.216), respectively. Male and aged 7–17 years were more sensitive to air pollutants. Through the temperature stratification analysis, we found that temperature could modify the impacts of air pollution on daily incidence of influenza with high temperature exacerbating the impact of air pollutants. At high temperature layer, male and the groups aged 0–6 years and 18–64 years were more sensitive to air pollution. Conclusion Temperature modified the relationship between air pollution and daily incidence of influenza and high temperature would exacerbate the effects of air pollutants in Ningbo.

Current Paradigm

The current paradigm of urinary tract infection (UTI) pathogenesis takes into account the contamination of the periurethral space by specific uropathogens residing in the gut, which is followed by urethral colonization and pathogen ascension to the urinary bladder. Consequently, studying the relationship between gut microbiota and the subsequent development of bacteriuria and UTI represents an important field of research. However, the well-established diagnostic and therapeutic paradigm for urinary tract infections (UTIs) has come into question with the discovery of a multifaceted, symbiotic microbiome in the healthy urogenital tract. More specifically, emerging data suggest that vaginal dysbiosis may result in Escherichia coli colonization and prompt recurrent UTIs, while urinary microbiome perturbations may precede the development of UTIs and other pathologic conditions of the urinary system. The question is whether these findings can be exploited for risk reduction and treatment purposes. This review aimed to appraise the three aforementioned specific microbiomes regarding their potential influence on UTI development by focusing on the recent studies in the field and assessing the potential linkages between these different niches, as well as evaluating the state of translational research for novel therapeutic and preventative approaches.

Ultra High Temperature

An investigation was undertaken into the relationship between the enzyme activity of cells harvested from raw milk and time taken for age gelation (TAG) to occur in the milk after ultra-high-temperature processing. It was shown that there was no relationship between the TAG and the bacterial counts on milk agar at 30°C or 7°C nor was there a relationship between the counts and the level of enzyme activity of the harvested cells. There was, however, a significant correlation between the level of enzyme activity of the harvested cells and the TAG. When extra bovine leucocytes were added to raw milk before processing, the TAG was increased. This suggested that there was an inhibitory action of leucocytes in development of age gelation.

The Relationship

Slopes in weakly cemented glaciolacustrine sediments in the Morkill River valley in the Canadian Rocky Mountains stand at up to 70°. Based on field and laboratory observations it appears that a contributing factor to instability is the softening of the soils by frost action and the leaching of calcite cement. Field density profiles demonstrated increased density and carbonate content with an increase in depth. Laboratory tests of carbonate content indicated a positive correlation between calcium carbonate and density in the glaciolacustrine sediments. The relationship was strongest in sands, in which leaching and dissolution were important components of softening. In clays, frost action was the dominant component of softening. Freeze-thaw tests showed a 50% decrease in strength after one cycle of freeze and thaw in the silts and clays.Key words: landslide, cemented, glaciolacustrine sediments, British Columbia.

Superconducting Applications

With the growing potential for use of Bi-2212 powders in high temperature superconducting applications, it is important to understand the processing characteristics of the material. To meet this need, the present work established the relationship between confining pressure and green density for powders of different particle sizes and morphologies. Mechanical properties, including elastic and plastic behavior, of the resulting green compacts were also measured as a function of relative density. Particle size and size distribution are shown to have a significant impact on the properties of interest. The implications of such findings are discussed with respect to the powder-in-tube process for making high temperature superconducting wire and tape.

The Relationship

A mother's expectations about the development of her infant have been found to be a strong determinant of child development, but little is known about the factors that may affect maternal assessment of development. In this study, the relationship of the mother's opinion of the development of her infant with several sociodemographic, antenatal, intrapartum, and infant health variables was examined for a large sample of 1-year-old infants for whom gross motor observations were also obtained at the time of the interview. Among those observed to be developing at an appropriate rate, 4.0% were perceived by their mothers as developing more slowly than the mothers considered normal; among infants developing more slowly, 28.6% were considered to be developing slowly by their mothers. In both groups, the major determinants of maternal opinion of slow development concerned the infant's health: low birth weight, congenital anomalies regardless of severity, hospitalization during the first year of life, and high ambulatory care use. These results indicate that maternal perception of infant development may not reflect the infant's level, but past or present illness, and raise questions about the influence of infant health on maternal-infant interactions and the effect of such interactions on subsequent development in the child.
