Latent tuberculosis infection (LTBI) remains the main source of new active tuberculosis (TB) cases worldwide. Household close contacts (HCCs) are at high risk of acquiring LTBI and subsequent development of TB. In this study, we aim to identify risk factors associated with LTBI in HCCs of TB patients living in a low TB-incidence setting. Our results revealed that HCCs who are aged more than 50 years (OR = 4.05) and overweight (OR = 15.3) are at higher risk of acquiring LTBI. None of these LTBI household contacts progressed to active TB. These findings suggest that HCCs who are young adults and children with normal and low body mass index are less likely to acquire LTBI after exposure to TB patients, even in low TB-incidence settings.

En este trabajo se propone el proceso de pirólisis como una posible vía de tratamiento de purines, que permite obtener energía renovable y un sólido, denominado biochar, con propiedades como enmienda orgánica. Se estudia el efecto de la temperatura de pirólisis sobre las propiedades del biochar.

Although microeconomics and macroeconomics differ in their object of study-microeconomics studies how economic individual agents make decisions and how those decisions interact, while macroeconomics studies the fluctuations of the economy as a whole-there is a significant tradition in economics that argues that macroeconomic models to be seen as epistemically compelling need to be given microfoundations. That is, 'macro' aggregates need to be shown to be derivable from the choice patterns of individual economic agents.This dissertation focuses on arguments that take macroeconomic and microeconomic entities' respective ontological natures as the reason why macroeconomics cannot be fully microfounded (
