Composite polymer/ceramic filaments for material extrusion-based fused filament fabrication additive manufacturing, using barium strontium titanium oxide (BST) ceramics and acrylonitrile butadiene styrene (ABS) thermoplastics were produced; their dielectric physical properties have been characterised the first time. The properties, relative permittivity (εr), quality factor (Q×f) loss (tanδ) me...
Fiber Metal Laminates (FMLs) are hybrid materials that combine metal components with fiber-reinforced composites. The properties and failure modes of CArbon fiber Reinforced composites/Aluminum (CARALLs) composed T700/PA6 unidirectional prepreg 6061 aluminum alloy were studied using experimental numerical simulation analysis. Through three-point bending experiments, the behavior CARALLs differe...
BACKGROUND AND AIM: We sought to carry out a systematic review and meta-analysis of the diagnostic value of epicutaneous patch testing in patients with oral lichenoid lesions (OLLs). METHODS: Bibliographic searches were conducted in electronic databases such as PubMed, the Cochrane library, EBSCO, Scopus, Web of knowledge and Google scholar from January 1990 to December 2011. Search terms re...
Experimental investigation of the ultimate resistance of slender, steel-plate girder web panels to combined shear-and-patch loading indicates significant interaction between shear loading and patch loading. However, an existing interaction formula is based on experimental results. Herein, an improved design procedure for slender plate girders subjected to combined shear and patch loading is pro...
The aim of this study is investigates the effects of different patches shrubs on the soil surface indicators in Gub Gugeh rangelands, in Golestan Province. The sampling was taken along transects of 50 meters, which are 10 meters away from each other. Via LFA models, three factors of stability, infiltration and nutrient cycling using 11 indicators of surface soil in patch and inter-patch were me...
Determining landscape parameters influencing species richness of habitat patches is one of the most important issues in conservation biology. Many previous studies have investigated the influence of habitat parameters on bird assemblages in forest patches, but studies seeking effects of oasis parameters on bird assemblages are very scarce. Karkas Protected Area is located in semi-arid zone in...
