Background: For psychiatric disorders, comorbidity is a rule rather than exception. Thus it is particularly important to study additive and multiplicative effects of multiple mental disorders on suicidal behaviors. Objectives: The aim of this study was to investigate the ethnic differences in multiplicative effects of mental disorders on suicidal ideation among Black adults in the United States...

The stress configuration and tectonic analysis of the Pan – African orogeny is drawn from the Igarra schist belt, southwestern Nigeria. The analysis of conjugate shear fractures of the schist belt indicates that two distinct compressive events (NE – SW and E – W) occurred in this Pan – African mobile zone. The palaeostress systems reveal a clockwise rotation of compressional axis from D1 (NE – ...

objective: to evaluate the possible interaction between religious beliefs and psychiatric disorders among black americans. methods: in this study, we used data of 5181 adult black americans who had participated in national survey of american life (nsal) from february 2001 to june 2003. variables such as socio-demographics, religious beliefs, and psychiatric disorders were entered in a cox regre...

in order to study the signs of œstrus in the west african dwarf goat, 28 non pregnant females younger than 24 months of age were used. most of them (94.7%) had waggled the tail during heat. the frequency of micturition was higher in the presence of the male. the swelling of the vulva was observed in 68.4% of goats in heat. the cervico-vaginal mucus was significantly (p≤0.05) abundant and elasti...

background: in the present study, the submandibularsalivary gland microscopic morphology of the adult africangiant pouched rat was investigated. this study was carried out toprovide the basic histology of this organ in the giant pouched rat,to accompany the dearth of information of its microscopicarchitecture in the available literature. this becomes of evenhigher importance when considering th...

the study of the potntial for using leucaena leucocephala or manihot esculentafor supplementing feeding of west african dwarf goats were carried out from november 2003 to january 2004 inthe experimental farm of the universityof dschang. twenty four west african dwarf goats, were divided in three groups of eight animals, each one 12 months old with average weight of 13.1±4.4 kg, were used in thi...

Over the years, the African continent has had to battle several outbreaks of infectious diseases in different countries. Some of the most deadly were the Ebola virus disease (EVD) outbreaks that occurred in West Africa between 2014 and 2016 affecting Guinea, Liberia, and Sierra Leone and, more recently, from 2018 to 2020 in the Democratic Republic of Congo (DRC). In the era of the COVID-19 pand...

Ionospheric slab thickness is defined as the ratio of TEC to maximum electron density of the F-region (NmF2), proportional to the square of the F2-layer critical frequency (foF2). It is an important parameter in that it is linearly correlated with scale height of the ionosphere, which is related to electron density profile. It also reflects variation of the neutral temperature. Therefore, ionos...
