although bearing capacity of footings on top of slopes under monotonic loadings have been investigated widely so far, safety and bearing capacity of these structures against repeated dynamic loads have not been considered well enough. in this paper, lower bound dynamic shakedown theorem in its numerical form has been employed to firstly obtain bearing capacity of strip footings on top of slopes...
Virus markers associated with vertical transmission of human T lymphotropic virus type 1 in Jamaica.
In a prospective study involving 150 mothers and their offspring in Jamaica, we examined maternal viral factors associated with the risk of transmission of human T lymphotropic virus type 1 (HTLV-1). Overall, the incidence of HTLV-1 infection among children was 8.3 occurrences per 1000 person-months. A higher maternal provirus level (odds ratio [OR], 1.9 per quartile) and a higher HTLV-1 antibo...
BACKGROUND To better understand potential transmission risks from contact with the body fluids of children, we monitored the presence and amount of CMV shedding over time in healthy CMV-seropositive children. METHODS Through screening we identified 36 children from the Atlanta, Georgia area who were CMV-seropositive, including 23 who were shedding CMV at the time of screening. Each child rece...
We examined the impact of environmental characteristics, such as habitat type, topographic exposure and presence of leaf litter, on the abundance of Ixodes pacificus ticks infesting the western fence lizard (Sceloporus occidentalis) at the University of California Hopland Research and Extension Center (HREC), Mendocino County, California. A total of 383 adult lizards were slip-noosed and examin...
The performance of an interconnection network is measured by two metrics: average latency and peak network throughput. Network throughput is the total number of packets delivered per unit of time. Most synthetic network loads consist of sources injecting at the same given rate, using traffic patterns such as random, permutations or hot spot, which reflect the distribution of packet destinations...
This research presents effect of triacetin and ethanol as additive to biodiesel (Neem oil methyl ester) on the performance and emission characteristics of a diesel engine at different loads and constant engine speed. Compared with biodiesel, slightly lower brake specific energy consumption for triacetin and ethanol bended fuels was observed. At higher engine loads CO,HC and smoke emission were ...
BACKGROUND Acute enterovirus (EV) meningitis is a major cause of hospitalization among adults and children. It is caused by multiple EV genotypes assigned to 4 species (EV-A, EV-B, EV-C, and EV-D). METHODS We determined viral loads in the cerebrospinal fluid (CSF) of 156 patients of all ages with EV meningitis during a 5-year observational prospective study. The virus strains were genotyped, ...
