We consider isotropic non lower semicontinuous weighted perimeter functionals defined on partitions of domains in R. Besides identifying a condition on the structure of the domain which ensures the existence of minimizing configurations, we describe the structure of such minima, as well as their regularity.

Conservation tillage has been promoted as a solution to counteract constraints caused by intensive agriculture. In this work the effects of two conservation tillage systems, reduced tillage (RT) and no-tillage (NT) were compared to the traditional tillage (TT) in a long(15 years, RT) and short-term experiment (3 years, NT). Both experiments were carried out under semi-arid, rainfed agriculture ...

Mediterranean temporary ponds (MTPs) comprise an endangered habitat with several endemic species that can be found in many countries, mainly in the Mediterranean region but are disappearing at a high rate. For designing optimal conservation and management strategies for the particular ecosystems, appropriate characterization and classification of these ponds is necessary based on the different ...

Recently, on-line adaptation of binary classifiers for tracking have been investigated. On-line learning allows for simple classifiers since only the current view of the object from its surrounding background needs to be discriminiated. However, on-line adaption faces one key problem: Each update of the tracker may introduce an error which, finally, can lead to tracking failure (drifting). The ...

In arid and semi-arid stream-dominated systems, the temporal variability in groundwater recharge has not been widely addressed. Various questions remain about sources of recharge, its patterns, appropriate measuring techniques. Hence, main objective present study was to assess changes that might affect pattern under wetter than normal surface water availability. Therefore, depth monitored near ...

familialmediterranean fever (fmf) is a hereditary syndrome characterized by recurrent attacks of fever and serositis. liver involvement in fmf has been reported in association with amyloidosis or rarely with vasculitis.in this report, a 32 year-old man with recurrent attacks of fever, abdominal pain and arthralgia is described who had moderate increase in liver transaminases only during disease...

glucose-6-phosphate dehydrogenase (g6pd) in humans is in x-linked disorder, housekeeping enzyme and vital for the survival of every cell. it catalyses the oxidation of glucose-6-phosphate to 6-phospho gluconat in the first committed step of the pentose phosphate pathway, which provides cells with pentoses and reducing power in the form of nadph. nadph is required to protect the cells against ox...

The distribution patterns of taxa belonging to the section Hypoglottidei DC. were investigated using DIVA-GIS software. Based on Zohary classification, five global patterns, with the exception of widely distributed species, include 1. Centro-Asiatic province, 2. Irano-Anatolian province, 3. Pontic province, 4. East Mediterranean subregion and 5. West Mediterranean subregion, were identified. In...
