Tuberculous meningitis (TBM) is a severe complication of tuberculosis and occurs mainly during early childhood. The incidence rate of TBM varies with season, and serum vitamin D levels, which are dependent on sunlight, might play a role. We studied the association between TBM incidence rate and hours of sunshine in Cape Town, South Africa and found a significant association between the incidenc...

Based on urban planning theory, the paper conducts a study on the D/H ratio of city road and applies a new technology BIM to make a quantitative objective analysis on the space size of road, differing from traditional subjective evaluation from the perspectives like psychology, physiology, social behavior and urban esthetics. Through the simulation and analysis on sunshine, ventilation under di...

I examine the impact of happiness on economic behavior. I use self-reported happiness data from the DNB Household Survey from the Netherlands and the German SocioEconomic Panel. I consider changes in regional sunshine as an exogenous determinant of happiness. Both long-run and transitory increases in sunshine increase happiness. Instrumenting individual happiness with regional sunshine, I find ...

Besides 2 m temperature and precipitation, sunshine duration is one of the most important and commonly used parameter in climatology, with measured time series of partly more than 100 years in length. EUMETSAT’s Satellite Application Facility on Climate Monitoring (CM SAF) presents a climate data record for daily and monthly sunshine duration (SDU) for Europe and Africa. Basis for the advanced ...

BACKGROUND AND OBJECTIVE Several studies have shown wide prevalence of vitamin D deficiency with serum 25(OH)D <49.9 nmol/L in urban Indians related to their poor sunshine exposure and skin pigmentation. However, there is limited information in rural Indians. We hypothesized presence of higher 25(OH)D in rural subjects as compared to urban because of farming related abundant sunshine exposure. ...
