The global data for the drop size distribution indicate that it is more similar to a gamma distribution http://www.selleckchem.com/products/Dasatinib.html than to an exponential one. Although disdrometers generally do not provide exactly the same rainfall values as rain gauges, a correction of the sampling area could reduce these differences.In conclusion, the nominal area of the sampling should not be considered as final, without previously calculating the possible error we may introduce into the calculations.

Toxocariasis is a parasitic zoonosis that causes significant morbidity worldwide. It is caused by nematodes of the genus Toxocara, which includes more than 30 species, of which two are important for humans: Toxocara canis and Toxocara cati [1]. Infection occurs in children by ingestion of eggs from T. canis via hands contaminated by direct contact with puppies, through the hair of the dog [2], or by ingestion of vegetables or soil contaminated with Toxocara eggs [3]. Consumption of raw liver from Toxocara-infected paratenic hosts is a less frequent source of contamination [4]. Seroprevalence in children is variable and can be as low as 1% reported in Spain [5] or as high as 67% reported in Argentina [6]; within each region or country prevalence can also vary widely, as in Brazil where there are locales with 8.

7% and others up to 54.8% rates [7, 8]. Geophagia and the use of public parks have been recognized as risk factors for Toxocara in children but others have been poorly evaluated [9], so the objective of this study was to evaluate the seroprevalence of Toxocara canis in children and its association with several factors such as their health, hygiene practices, and pets.2. Materials and Methods2.1. Study Location A cross-sectional study was carried out between August and September 2010 in the Municipality of Ecatepec of Morelos (Latitude 19�� 36��03���N and Longitude 99�� 03��09���W). Ecatepec is a city in the metropolitan area of Mexico City located in the north of the State of Mexico and north of the Mexican Valley; it has a mean altitude of 2,259m above sea level and is an area with high population density and industrial zones.

This district has a population of 1,656,107 inhabitants. Ecatepec has a temperate subhumid climate with rains in summer, with a mean temperature of 13.8��C (between 7 and 30��C) and an average relative humidity of 35%. 2.2. Data CollectionInterviews were carried out in the schools of participants, with informed consent from a parent and/or legal GSK-3 guardian and the assent of the children.
