In this communication, a novel method to characterize the thermal dilatation of metals using contactless measurement frequency-dependent reflection coefficient resonator is introduced. This wireless technique allows extracting expansion material without need any calibration. Two antennas, VNA, and scatterer fabricated with under-test are required. All measurements have been achieved climatic ch...

An innovative method against late frosts in vineyard has been developed at CIRIAF, University of Perugia. It consists an organic coating made by cotton candy and straw to prevent the vine shoots freezing due frosts. This technique already tested lab-scale with very encouraging results. paper aims experiment effect applied on young grapevine during artificially controlled frost events. A shoot c...

optical rehabilitation of the patient with aphakia who cannot tolerate contact lenses present a therapeutic challenge. in the absence of capsular support, anterior chamber lenses have been widely used. on the other hand intraocular lens implantation of scleral sutured posterior chamber intraocular lens during penterating keratoplasty or insufficient iris support is recommended. the purpose of t...

The usage of electronics in outdoor environment is growing therefore the control moisture related failures are becoming more important. main cause these humidity inside which may condense on surfaces or components. To protect from harsh environment, components and encapsulated by using enclosures, however it does not prevent ingress through plastic walls, gaskets, cable feedthroughs etc. Thus, ...

BACKGROUND In this study, Aloe vera samples were collected from different climatic regions of India. Quantitative HPTLC (high performance thin layer chromatography) analysis of important anthraquinones aloin and aloe-emodin and antiplasmodial activity of crude aqueous extracts was done to estimate the effects of these constituents on antiplasmodial potential of the plant. METHODS HPTLC system...

Grand challenges in global change research and environmental science raise the need for replicated experiments on ecosystems subjected to controlled changes in multiple environmental factors. We designed and developed the Ecolab as a variable climate and atmosphere simulator for multifactor experimentation on natural or artificial ecosystems. The Ecolab integrates atmosphere conditioning techno...

BACKGROUND Although some authors have suggested that there is some seasonal periodicity of hemoptysis, or relation to respiratory tract infections, the association of influenza or climatic parameters with hemoptysis has been poorly investigated. Our aim was to describe the relationship between influenza and climatic parameters with severe hemoptysis that required bronchial artery embolization (...

Organisms face continual fluctuations in global climatic processes to which they must adapt or perish. Considering that many species are key habitat formers and energy producers, such responses to climate change can have significant population, community and even ecosystem consequences. Paleo-records of ecosystem responses to past environmental variability have proven invaluable for studying im...

BACKGROUND AND AIMS Local climatic adaptation can influence species' response to climate change. If populations within a species are adapted to local climate, directional change away from mean climatic conditions may negatively affect fitness of populations throughout the species' range. METHODS Adaptive differentiation to temperature was tested for in American ginseng (Panax quinquefolius) b...
