RESUMENEl presente trabajo describe el uso de herramientas de tecnologías de la información y la comunicación como apoyo al proceso de aprendizaje, las cuales están basadas en aplicaciones propias de las computadoras con las características de Software Libre así como aplicaciones propias de la Web 2.0. Asimismo, se presenta la concepción de utilizar las computadoras como herramientas cognitivas para promover y desarrollar distintas habilidades del pensamiento. Posteriormente se enlistan por categorías algunos ejemplos de herramientas de la mente los cuales pueden ser descargados de internet o ser utilizados en línea.Palabras clave: software libre, web 2.0, herramientas de la mente, herramientas cognitivas, ntic, tipos de pensamiento. ABSTRACTThis paper describes the use of information and communication technology tools to support learning. The tools presented are classified in the category of free software and web 2.0 applications. The view of using computers as cognitive tools to promote and develop skills of the different types of thinking. Later, some examples of mindtools are presented by categories that can be downloaded from internet or used on line directly.

Agriculture (including livestock) is considered one of the main sources of greenhouse gases. Monitoring greenhouse gases (GHG) is necessary in this activity, and there are several methodologies. One of these methodologies is the eddie covariance technique, which can analyze GHG in a continuous manner. Accordingly, the installation and evaluation of a GHG-2 system was proposed for monitoring CH4 and CO2 in a dairy herd in a semi-confined system in Sonora. The results show that the GHG-2 can evaluate the continuous behavior of the CH4 and CO2 emissions, observing peaks of both gases when the cattle were present. It also corroborated the existence of a good relationship between both GHG (CH4:CO2), similar to previous studies, where this ratio was used to estimate methane emissions indirectly through energy balances to calculate CO2. One of the limitations of this technique in confined or semi-confined systems is the presence of particulate matter in the atmosphere that requires frequent monitoring and maintenance of the equipment, as well as the high consumption of energy, which forces us to consider solar panels and batteries to supply an adequate flow of electricity if another continuous source of electricity is not available.

At the First Meeting of Regional Climatology of Northwestern Mexico, 20 researchers from several Mexican universities and research institutions discussed the impact of climate variability on water resources and ecological sustainability in northwestern Mexico. This subtropical region has meteorological and climatological behaviors characteristic of both the mid‐latitudes and the tropics. Given the semiarid to arid nature of the climate, precipitation is quite variable and is projected to become more so in current climate change projections.
