For times dgapa unam than the duration of the ejection pulse, this tail develops a linear radial velocity vs. We study the case of a Gaussian ejection velocity law dgapa unam a constant and a Gaussian ejection density history, dgapa unam, We compare these two cases, and find that the main effect of the different ejection density histories is to change the mass and the density stratification of the plasmon tail. This type of structure is seen in some planetary nebulae; examples are described by Alcolea et al.

Students can post questions and collaborate to edit responses to these questions. Instructors can also answer questions, endorse student answers, and edit or delete any posted content. Piazza is designed to simulate real class discussion. It aims to get high quality answers to difficult questions, fast! The name Piazza comes from the Italian word for plaza--a common city square where people can come together to share knowledge and ideas. We strive to recreate that communal atmosphere among students and instructors.

The deadline for applications is January 18 Please write to david. The Research Institute on Ecosystems and Sustainability IIES of the National Autonomous University of Mexico UNAM is devoted to research, capacity building and creating bonds with different sectors of society in order to understand environmental problems related to the management of socio-ecological systems. Thus, its main approaches are interdisciplinary and transdisciplinary research done across scales. The IPBES is responsive to the interests of decision makers all around the world and seeks to integrate science and policy in order to promote better decisions regarding the management of ecosystems. Moreover, it aims at offering scientific, technical and logistic support to the Core Group on Values, the Multi-Expert Panel and the Secretariat. The recent approval of the Bureau for the creation of this TSU has generated opportunities regarding the topic of values for the TSU and the IPBES, which may be of interest for a creative candidate interested in this postdoctoral position. This candidate will develop postdoctoral activities on the project detailed below: Central topic of the postdoctoral position: Integration of multiple values in decision making across scales, from global to local scales. Description of the activities: The postdoctoral activity will explore how multiple values of nature and its contributions to quality of life have been incorporated in decision making at global, national and local scales. We are looking for outstanding candidates with excellent inter-personal communication skills, who are independent and creative, and with proven commitment and excellent academic performance. The candidates applying for this position should also have experience working or interacting with experts with multiple backgrounds as well as with decision-makers from diverse governmental and non-governmental contexts. Moreover, the candidates should have a proven ability to communicate fluently in both English and Spanish. We are expecting candidates with studies in environmental and earth sciences, political sciences, communication, sociology or ecological and environmental economics.

Raga, A. They should also have proven productivity, i.

Multimetallic systems, instead of monometallic systems, have been used to develop materials with diverse supported species to improve their catalytic, antimicrobial activity, etc. A low silver content leads to the formation of reduced silver clusters, while the formation of nanoparticles of a bigger size takes place in the trimetallic samples with high silver content. The cooling of the reduced trimetallic samples in the air causes the oxidation of the obtained metallic clusters and silver and copper nanoparticles. In the case of copper, such conditions lead to the formation of mainly copper II oxide, while the silver nanospecies are converted mainly into clusters and nanoparticles. The zinc cations provoked changes in the mordenite matrix, which was associated with the formation of point oxygen defects in the mordenite structure and the formation of surface zinc oxide sub-nanoparticles in the samples cooled in the air. Keywords: copper; mordenite zeolite; nanospecies; silver; thermal redox; trimetallic system; zinc.

In the case of copper, such conditions lead to the formation of mainly copper II oxide, while the silver nanospecies are converted mainly into clusters and nanoparticles. Alcolea, J. Therefore, the leading head has to asymptotically approach a velocity. For the density structure, we see that there is a peak just before the head of the plasmon. Dennis, T. Please enter your unam.

Generate a personal research project related to strengthening the science-policy interphase on incorporating the multiple values of nature into decision-making. The head of the plasmon has a mass given by the contribution from the ejection pulse see equation 28 and a contribution from the environment:.

Abstract Multimetallic systems, instead of monometallic systems, have been used to develop materials with diverse supported species to improve their catalytic, antimicrobial activity, etc. The color figure can be viewed online. Supervisor: Dr. Raga et al, studied the problem of a collimated flow produced by a parabolic, single pulse ejection velocity variability. For times greater than the duration of the ejection pulse, this tail develops a linear radial velocity vs. We recover the result of Raga et al. Let us now consider an ejection with a Gaussian velocity variability see equation 4 and also with a Gaussian density variability:. As discussed, e.
