Tropical dry forests are the most threatened tropical terrestrial ecosystem. However, few studies have been conducted on the natural regeneration necessary to restore these forests. We reviewed the ecology of regeneration of tropical dry forests as a tool to restore disturbed lands. Dry forests are characterized by a relatively high number of tree species with small, dry, wind-dispersed seeds. ...

We give a further examination of the stabilized Residual Distribution schemes for the solution of the shallow water equations proposed in (Ricchiuto and Bollermann, J.Comp.Phys., available online 25 October 2008). Based on a non-linear variant of a Lax-Friedrichs scheme, the scheme is wellbalanced, able to handle dry areas and, for smooth regions of the solution, obtains second order of accurac...

the objective of this research was to determine the best model and compare performances in terms of producing landuse maps from six supervised classification algorithms. as a result, different algorithms such as the minimum distance ofmean (mdm), mahalanobis distance (md), maximum likelihood (ml), artificial neural network (ann), spectral anglemapper (sam), and support vector machine (svm) were...

It can be observed that the environmental focus on the climate change debate has ignored contribution of political factors in preventing famines. The question arises why famines occur much more frequently in some dry land areas than in others need to be answered satisfactorily. Can democracy contribute to prevent famines in dry land areas with adversely affected by climate change? As famine is ...

To avoid unnecessary waste of limited resources and to help prioritize areas for conservation efforts, this study aimed to provide information on habitat use by elephants between the wet and dry seasons in the Mole National Park (MNP) of Ghana. We compiled coordinates of 516 locations of elephants' encounters, 256 for dry season and 260 for wet season. Using nine predictor variables, we modeled...

Sustainable architecture is known as an important strategy in recent years and all around the world are cooperating to achieve this by use of natural elements. There are many examples of residential buildings in Iran s past and its traditional architecture that the architecture in the interim of paying attention to aesthetic issues and preserving the natural environment acts in a way that meets...

The low prevalence of gingival recessions observed in orthodontic clinical practice may be assigned to the fact that in studies in which dehiscences and bone fenestrations are described as frequent, they were diagnosed based on: 1) dry skull studies; 2) areas with periosteal reflection together with flap; and 3) imaging techniques with low sensitivity to detect these defects, which have a delic...

Although it is well known that isocapnic hyperventilation (IHV) with dry cold air produces airway constriction in asthmatic subjects, the site of airway narrowing is nuclear. To address this issue, we have quantified the tracheal and bronchial response to IHV with dry cold air in 15 patients with mild asthma and 7 healthy control subjects. We employed the acoustic reflection technique to evalua...
