The experimental idea of the present project was elaborated in order to create a structure where different categories and institutions could collaborate, with the common aim to develop a sustainable and profitable agriculture in mountain and marginal areas. The target was the recovering of an abandoned agricultural site, throughout its re-organisation, re-qualification and auto-sustainability, involving local citizens. This approach was based on three further broad functions such as environmental, economic and social purposes. This cooperation, that allows the capitalization of local knowledge and the forging of relationships between local and external sources of expertise, information and advice, is fundamental to the future of existing rural communities, in particular in mountain areas. The model proposed, with the elaboration of a management software and technical agronomic sheets, could be an incentive for the activities already present in that region and to stimulate new ones. The enhancing of the native ecological system, the biodiversity tutelage and the valorization of the knowledge of the territory is the basic requirement for the successful of any land management.

Tree height (H) in a natural stand or forest plantation is a fundamental variable in management, and the use of mathematical expressions that estimate H as a function of diameter at breast height (d) or variables at the stand level is a valuable support tool in forest inventories. The objective was to fit and propose a generalized H-d model for Pinus montezumae and Pinus pseudostrobus established in forest plantations of nuevo San Juan Parangaricutiro, Michoacan, Mexico. Using nonlinear least squares (nLS), 10 generalized H-d models were fitted to 883 and 1226 pairs of H-d data from Pinus montezumae and Pinus pseudostrobus, respectively. The best model was refitted with the maximum likelihood mixed effects model (MEM) approach by including the site as a classification variable and a known variance structure. The Wang and Tang equation was selected as the best model with nLS;the MEM with an additive effect on two of its parameters and an exponential variance function improved the fit statistics for Pinus montezumae and Pinus pseudostrobus, respectively. The model validation showed equality of means among the estimates for both species and an independent subsample. The calibration of the MEM at the plot level was efficient and might increase the applicability of these results. The inclusion of dominant height in the MEM approach helped to reduce bias in the estimates and also to better explain the variability among plots.

In the present paper, the authors introduce a new subclass of p-valent analytic functions with complex order defined on the open unit disk U={z:z∈C and |z|nd obtain coefficient inequalities for the functions in these class. Application of these results for the functions defined by the convolution are also obtained.

In 2002, the Vienna Cancer Stem Cell Club （VCSCC） was inaugurated by a group of scientists at the Medical University of Vienna, with the primary goal to initiate and promote cancer stem cell （CSC） research in Austria and to exploit knowledge from this new discipline in translational approaches, During the first years following inauguration, the VCSCC-community was small and left without major funding. However, over time the consortium was able to launch several major project-lines, supported in part by the national Science Funds, a Genome Program, and the Ludwig-Boltzmann Society. Today, the VCSCC provides a robust intellectual platform for ongoing research in the field of translational oncology and CSC-research in Austria. In addition, the VCSCC is connected to several major CSC-networks and centers in Europe and in north America, and is a well-recognized group in the field. The VCSCC also organized a series of CSC Meetings and Conferences, and contributed essentially to a recently published classification of CSC. There is also hope that the VCSCC-consortium will further advance the field of CSC research in the future, and will create novel concepts, with the ultimate aim to improve anti-cancer therapy through elimination, suppression, or long-term control of cancer-initiating cells.
