This study examines the relationship between climatic indicators (maximum temperature, minimum precipitation, and relative humidity) spread of COVID-19 using weekly data confirmed cases death rates from 3/25/2020 to 12/30/2020 for Nigeria, South Africa, Ghana. Using an ex-post research design descriptive method analysis, results confirm evidence correlation variables virus among three selected ...

Ice nucleating particles active at warm temperatures (e.g. -8 °C; INP-8) can transform clouds from liquid to mixedphase, even at very small number concentrations (<10 m). Over the course of 15 months, we found very similar patterns in weekly concentrations of INP-8 in PM10 (median = 1.7 m, maximum = 10.1 m) and weekly amounts of rainfall (median = 28 mm, maximum = 153 mm) at Birkenes, southern ...

Attentive monitoring and regular repair of concrete cracks are necessary to avoid further durability problems. As an alternative to current maintenance methods, intrinsic repair systems which enable self-healing of cracks have been investigated. Exploiting microbial induced CaCO3 precipitation (MICP) using (protected) axenic cultures is one of the proposed methods. Yet, only a few of the sugges...

The Arctic is one of the ecosystems most affected by climate change; in particular, winter temperatures and precipitation are predicted to increase with consequent changes to snow cover depth and duration. Whether the snow-free period will be shortened or prolonged depends on the extent and temporal patterns of the temperature and precipitation rise; resulting changes will likely affect plant g...

Power spectrum techniques are applied to series of daily, weekly, and monthly average temperature and precipitation values, recorded since 1870 at the Woo'dstock Climatologioal Benchmark Station in Maryland, in order to gain a reasonable interpretation of the extent and frequency distribution of periodic variations in these data. Analysis procedures are outlined, and the results presented, inte...

OBJECTIVE To evaluate the association between weather (barometric pressure, precipitation and temperature) and pain among individuals with osteoarthritis (OA) (n=154) at the following sites: neck, hand, shoulder, knee and foot. METHODS This prospective study evaluated men and women, aged 49-90 yr, participating in a community-based, osteoarthritis exercise study (June 1998-January 2002). Week...

The local abundance of Culex mosquitoes is a central factor adding to the risk of West Nile virus transmission, and vector abundance data influence public health decisions. This study evaluated differences in abundance estimates from mosquitoes trapped using two common methods: CO2-baited CDC light traps and infusion-baited gravid traps in suburban, Chicago, Illinois. On a weekly basis, the two...

The object of this investigation has been to study (a) the conditions necessary for obtaining precipitation of vitamin C with basic lead acetate, (b) the use of n-butyl alcohol as a solvent, and (c) the stability of purified preparations stored in the laboratory. The general method employed for concentrating and assaying the antiscorbutic factor from lemons’ was the same as that previously repo...

Ice-nucleating particles (INPs) active at modest supercooling (e.g. −8 C; INP−8) can transform clouds from liquid to mixed phase, even at very small number concentrations (< 10 m−3). Over the course of 15 months, we found very similar patterns in weekly concentrations of INP−8 in PM10 (median= 1.7 m−3, maximum= 10.1 m−3) and weekly amounts of rainfall (median= 28 mm, maximum= 153 mm) at Birkene...

Hand, foot, and mouth disease (HFMD) causes characteristic blisters and sores mainly in infants and children, and has been monitored in South Korea through sentinel surveillance since 2009. We described the patterns of HFMD occurrence and analyzed the effect of climatic factors on national HFMD incidence. Weekly clinically diagnosed HFMD case rates (per 1,000 outpatients) in sentinel sites and ...
