Tuberculosis incidence based on the climate and the average of annual rain was evaluated using GIS. Data were analyzed through SPSS software.
The TB incidence was different in various geographic conditions. The risk of TB has a strong relationship with climate and the average of annual rain, so that the risk of TB in areas with low annual rainfall and extra dry climate is more than other regions. Services and special cares to high-risk regions of TB are recommended.

Storage capacity at CMS Tier-1 and Tier-2 sites reached over Petabytes in , and will be substantially increased during Run 2 data taking. For comprehensive tracking and monitoring of the storage utilization across all participating sites, CMS developed a space monitoring system, which provides a central view of the geographically dispersed heterogeneous storage systems. The first prototype was deployed at pilot sites in summer , and has been substantially reworked since then. Geographical analysis of diapause inducibility in European Drosophila melanogaster populations.
Seasonal overwintering in insects represents an adaptation to stressful environments and in European Drosophila melanogaster females, low temperatures and short photoperiods can induce an ovarian diapause. Diapause may represent a recent populations on both continents show a predictable latitudinal cline in diapause induction. Given the phenotype of ls-tim and its geographical distribution , we might predict that it would work against any latitudinal cline in diapause induction within Europe.
Indeed we reveal that any latitudinal cline for diapause in Europe is very weak, as predicted by ls-tim frequencies. In contrast, we determine ls-tim frequencies in North America and observe that they would be expected to strengthen the latitudinal pattern of diapause. Our results reveal how a newly arisen mutation, can, via the stochastic nature of where it initially arose, blur an otherwise adaptive geographical pattern. Published by Elsevier Ltd..

Sixteen sites Geographic distribution : Boiga irregularis Brown treesnake. Rota: Rota Seaport Shelwyn Taisacan, Robert Ulloa. Verified by G. USNM Snake 42 g, mm SVL, mm total length captured in a mouse-baited trap hung on the fence perimeter of the Rota Seaport.
Because the Northern Marianas Islands are historically snake-free, these traps are used around ports and airports for early detection of snakes that may stow away in vessels or aircraft from Guam 60 km to the south , possibly evading quarantine detections. Necropsy revealed no prey items in stomach or gas- trointestinal tract. Dissection at USNM confirmed the snake was female. To our knowledge, this is the first incursion of a live Boiga irregularis on Rota.

Geographic -time distribution of ambulance calls in Singapore: utility of geographic information system in ambulance deployment CARE 3. Pre-hospital ambulance calls are not random events, but occur in patterns and trends that are related to movement patterns of people, as well as the geographical epidemiology of the population.
This study describes the geographic -time epidemiology of ambulance calls in a large urban city and conducts a time demand analysis.
This will facilitate a Systems Status Plan for the deployment of ambulances based on the most cost effective deployment strategy. An observational prospective study looking at the geographic -time epidemiology of all ambulance calls in Singapore. Ambulance response times were mapped and a demand analysis conducted by postal districts. Between 1 January and 31 May , 31, patients were enrolled into the study. Mean age of patients was Race distribution was Trauma consisted Mean call receipt to arrival at scene was 8. Call volumes in the day were almost twice those at night, with the most calls on Mondays.
We found a definite geographical distribution pattern with heavier call volumes in the suburban town centres in the Eastern and Southern part of the country. We characterised the top 35 districts with the highest call volumes by time periods, which will form the basis for ambulance deployment plans. We found a definite geographical distribution pattern of ambulance calls.
This study demonstrates the utility of GIS with despatch demand analysis and has implications for maximising the effectiveness of ambulance deployment. Epstein-Barr virus EBV latently infects the majority of the human population and is implicated as a causal or contributory factor in numerous diseases. We sequenced 27 complete EBV genomes from a cohort of Multiple Sclerosis MS patients and healthy controls from Italy, although no variants showed a statistically significant association with MS. We discuss mechanisms that potentially explain these observations, and their implications for understanding the association of EBV with human disease.
Malignant tumours are encountered among all races and in every type of geographical zone, but there are marked differences in different areas in the prevalence of particular forms of tumour—differences that are to a greater or lesser extent dependent on factors such as the climate and geography of the region and the habits, customs and occupations of the people.
The study of these factors in relation to the occurrence of malignant tumours is of great importance in reaching an understanding of the etiology of tumours in man. In this paper the author discusses the many problems involved in the study of regional features in the prevalence of malignant tumours, with special reference to the difficulties of ensuring comparability of the data from widely differing regions and population groups.
He concludes the paper with a review of some known facts regarding the distribution of malignant tumours at various sites in which he compares data obtained in surveys in the USSR with those obtained in other countries. Knowledge of genetic diversity and pop Geographically distributed real-time digital simulations using linear prediction. Real time simulation is a powerful tool for analyzing, planning, and operating modern power systems. For analyzing the ever evolving power systems and understanding complex dynamic and transient interactions larger real time computation capabilities are essential.
These facilities are interspersed all over the globe and to leverage unique facilities geographically-distributed real-time co-simulation in analyzing the power systems is pursued and presented. However, the communication latency between different simulator locations may lead to inaccuracy in geographically distributed real-time co-simulations. In this paper, the effect of communication latency on geographically distributed real-time co-simulation is introduced and discussed. Two digital real time simulators are used to perform dynamic and transient co-simulations with communication latency and predictor.
Results demonstrate the effect of the communication latency and the performance of the real-time data predictor to compensate it.
Via, Marc; Gignoux, Christopher R. Contemporary genetic variation among Latin Americans human groups reflects population migrations shaped by complex historical, social and economic factors. Consequently, admixture patterns may vary by geographic regions ranging from countries to neighborhoods. We examined the geographic variation of admixture across the island of Puerto Rico and the degree to which it could be explained by historic and social events. We analyzed a census-based sample of Puerto Rican individuals that were genotyped for 93 ancestry informative markers AIMs to estimate African, European and Native American ancestry.
Socioeconomic status SES data and geographic location were obtained for each individual. There was significant geographic variation of ancestry across the island.
In particular, African ancestry demonstrated a decreasing East to West gradient that was partially explained by historical factors linked to the colonial sugar plantation system. SES also demonstrated a parallel decreasing cline from East to West. However, at a local level, SES and African ancestry were negatively correlated. European ancestry was strongly negatively correlated with African ancestry and therefore showed patterns complementary to African ancestry. By contrast, Native American ancestry showed little variation across the island and across individuals and appears to have played little social role historically.
The observed geographic distributions of SES and genetic variation relate to historical social events and mating patterns, and have substantial implications for the design of studies in the recently admixed Puerto Rican population. More generally, our results demonstrate the importance of incorporating social and geographic data with genetics when studying contemporary admixed populations.
