The life tables in this report are current life tables for the United States based on age-specific death rates in 1999. Data used to prepare these life tables are 1999 final mortality statistics; July 1, 1999, population estimates; and data from the Medicare program. Presented are complete life tables by age, race, and sex. In 1999 the overall expectation of life at birth was 76.7 years, unchan...

OBJECTIVES This report presents complete period life tables for the United States by race, Hispanic origin, and sex, based on age-specific death rates in 2008. METHODS Data used to prepare the 2008 life tables are 2008 final mortality statistics; July 1, 2008, population estimates based on the 2000 decennial census; and 2008 Medicare data for persons aged 66-99. The methodology used to estima...

Certain species of Hermetia illucens, also known as the Black Soldier Fly(BSF), were found in a compost plant in Roorkee located in Northern India. Its larvae arevoracious eaters of organic waste, hence can play an ecologically-important role in solidwaste management. Morphological analysis of various stages of BSF life cycle by SEMshowed that its body along with its wings is densely covered wi...

Ethylene plays an important role in wide-ranging aspects of plant growth and development, includingfruit ripening, leaf and flower senescence. In this study, the expression patterns of two genes involved in theethylene signal transduction pathway (RhCTR1 and RhCTR2) were investigated during the flower openingstages in two Rosa hybrida cultivars, ‘Black magic’ and ‘Maroussia’, ...

OBJECTIVES This report presents period life tables for the United States based on age-specific death rates for the period 1999-2001. These tables are the most recent in a 100-year series of decennial life tables for the United States. METHODS This report presents complete life tables by age, race (white and black), and sex. Also presented are standard errors of the probability of dying and li...

The Black Swan Theory was described by Nassim Nicholas Taleb in his book "The Black Swan". This theory refers to "high-impact, hard-to-predict, and rare events beyond the realm of normal expectations". According to Taleb's criteria, a Black Swan Event is a surprise, it has a major impact and after the fact, the event is rationalized by hindsight, as if it had been expected. For most of human hi...

BACKGROUND Uterine leiomyomata (fibroids) are hormonally responsive tumors, but little is known about risk factors. Early-life exposures may influence uterine development and subsequent response to hormones in adulthood. An earlier analysis of non-Hispanic white women who participated in the Sister Study found associations between several early-life factors and early-onset fibroids. OBJECTIVE...

Biologically meaningful and standardized definitions of life stages are essential for demographic studies, especially for endangered and intensively managed species such as rhinoceros. Focusing on the black rhinoceros Diceros bicornis, we argue that standardized biological definitions of calf, subadult, and adult, rather than age classes, provide the appropriate basis for black rhinoceros demog...

PURPOSE To describe how some Black Americans view advance directives. Current literature revealed that most prior studies used quantitative methods with force-choice questions and had few Black subjects. DESIGN Interviews were conducted with 17 Black Americans. Transcripts of the interviews were subjected to content analysis. FINDINGS Three major categories of themes were identified: Threat...
