After emerging from decades of civil war, Angola's economy has rapidly grown, yet its reproductive health outcomes have not improved at a commensurate level. At the time of this study, Angola had one of the highest rates of maternal mortality and fertility in the world. Only 6 percent of women aged 15-49 used contraception, with substantial differences in use and access across the different pro...
We analyze applications of knots and links in the Ancient art, beginning from Babylonian, Egyptian, Greek, Byzantine and Celtic art. Construction methods used in art are analyzed on the examples of Celtic art and ethnical art of Tchokwe people from Angola or Tamil art, where knots are constructed as mirror-curves. We propose different methods for generating knots and links based on geometric po...
The world species of Zambion Kasparyan (Hymenoptera: Ichneumonidae: Tryphoninae) are revised including re-descriptions of Zambion monodon Kasparyan and Zambion hirtum Delobel. Five new species are described: Zambion kasparyanisp. n., Zambion rogerisp. n., Zambion eileenaesp. n., Zambion wahlisp. n. andZambion broadisp. n. A key to species is provided. The genus is endemic to Africa (Angola to K...
Despite its isolation three decades ago, Ebola virus continues to cause periodic outbreaks of severe hemorrhagic fever in humans, and the closely related Marburg virus is responsible for a recent outbreak of disease in Angola. The mortality rate associated with Ebola virus infection can reach 90 percent, and so the prospect of an effective therapy is attractive. A recent study by Chandran et al. 1
Is Brazil’s Prolific Pre-Salt Petroleum Geology a Template for Oil & Gas Exploration in West Africa?
About 125 130 million years ago South America began to separate from Africa and as the continents drifted apart, an extensive rift valley was formed, containing large lakes with abundant organic material that had washed off the adjacent highlands. In Angola, these sediments are known as the Bucomazi formation, an exceedingly rich oil and gas source rock. The rift valleys are similar to the pres...
The authors present a case of Osteogenesis Imperfecta, emphasizing the clinical and epidemiological characteristics, forms of classification and treatment of the disease. This is an important case not only to the knowledge of pediatricians and orthopedists, but also for other professionals involved with the problem. This article has been jointly described by the Departments of Pediatrics and Ne...
OBJECTIVE To estimate the prevalence of nutritional deficiencies in Angolan children. METHODS A cross-sectional population based study. World Health Organization (2006) criteria were used to classify nutritional state. RESULTS A high prevalence of low height for age, weight for height and weight for age was observed (22%, 13% and 7%, respectively) among the children. CONCLUSIONS Nutrition...
This paper explores the impact of renewable energy on Angola's GDP and employment. The study used Autoregressive Distributed Lag (ARDL) error correction models with data use, gross domestic product, unemployment rate, industry employment, vulnerable labor force participation rate fixed capital formation. note contributes to existing literature by investigating effects use employment in a si...
It is widely recognized that the conservation of Crop Wild Relatives (CWR) in their wild habitats fundamental to ensure continuous supply novel genetic material, crucial for future crop improvement. Vigna unguiculata (cowpea) and V. subterranea (bambara groundnut) are amongst most significant African legumes as sources food fodder. In this study we investigated diversity species Angola, identif...
