Scratch Resistance of Paints Degraded by Arid Saharan Environments
In the vast Algerian Sahara, the climate is typically desert, characterized by heat and dryness all year, which contributes to a very pronounced aridity. The aim of this study is to investigate the impact of this arid environment on automotive paints. Four paint samples with different durations of use were tested. Initially, a visualization of the surface condition by optical microscopy and...
متن کاملPredicting the Future Impact of Droughts on Ungulate Populations in Arid and Semi-Arid Environments
Droughts can have a severe impact on the dynamics of animal populations, particularly in semi-arid and arid environments where herbivore populations are strongly limited by resource availability. Increased drought intensity under projected climate change scenarios can be expected to reduce the viability of such populations, yet this impact has seldom been quantified. In this study, we aim to fi...
متن کاملForage yield and quality of barley-annual medic intercrops in semi-arid environments
On-farm production of protein is limited in most dairy farm operations in arid and semi-arid environments. Cereal-legume intercropping could be a viable option to obtain forage with higher protein content. A two-year experiment was conducted during 2009 and 2010 growing seasons in a loamy soil to determine whether intercropping pattern of barley (Hordeum vulgare L.) and annual medic (Medica...
متن کاملDEM-based analysis of morphometric features in humid and hyper-arid environments using artificial neural network
Abstract This paper presents a robust approach using artificial neural networks in the form of a Self Organizing Map (SOM) as a semi-automatic method for analysis and identification of morphometric features in two completely different environments, the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) in a complex mountainous humid area and Yardangs in Lut Desert, Iran, a hyper...
متن کاملFractional vegetation cover estimation in arid and semi-arid environments using HJ-1 satellite hyperspectral data
This paper evaluates the usefulness of the hyperspectral imager (HSI) onboard Chinese HJ-1-A small satellite in vegetation mapping. Fractional vegetation cover (FVC) is an important surface microclimate parameter for characterizing land surface vegetation cover as well as the most effective indicator for assessing desertification and crop growth condition. The HJ-1/HSI data were used to calcula...
