Edible films and coatings have currently received increasing interest because of their potential in food applications. This study examined the effect incorporated essential oils natural plant extracts on characteristics composite seaweed hydrocolloid gac pulp films. Films were prepared by a casting technique, followed measurement physical, optical, barrier, mechanical, structural properties. Th...

conclusion st-vab and mgl-eb are reliable biopsy methods for microcalcifications. in proper indications, breast microcalcifications could be obtained by each method without missing diagnosis of breast cancer. objectives to evaluate the outcome of st-vab and mammography-guided localization and excisional biopsy (mgl-eb) for microcalcifications. patients and methods two radiologists retrospective...

Epidermolysis bullosa (EB) is a rare hereditary disorder characterized by formation of blisters following minor trauma. It has been traditionally categorized by the level of basement membrane zone separation into EB simplex (EBS), junctional EB (JEB), and dystrophic EB (DEB). Recently, hemidesmosomal EB has been proposed as a fourth category, which includes EB with muscular dystrophy and EB wit...

Halloysite nanotubes (HNTs) were incorporated into an EPDM/SBR rubber/styrene-butadiene rubber (SBR) composite by melt blending of HNTs the blend. The mechanical properties, abrasion and swelling resistance ranging from 2 parts per hundred (phr) to 10 investigated in base rubber. Tensile strength, 100% modulus (modulus at elongation), elongation break tear strength evaluated ambient temperature...

In this study, biodegradable kefiran-chitosan-nanocellulose blend films were developed and their physical, mechanical, barrier, thermal and structural properties determined. Results showed that adding nanocellulose had not any significant effect on the thickness, moisture content and water solubility. Also, water vapor permeability, tensile strength and lightness increased and the elongation at...

A new class of biobased composites with tailorable mechanical properties made natural fibers, polylactic acid, and ferulic acid derivatives (FAD) is studied. FAD was used to develop elastomeric like improved elongation at break highly reversible deformation upon elongation. Composites were prepared using raw enzymatically treated hemp fibers. The fibers defibrillated due the enzymatic treatment...

nanocomposites based on polyamide 6 (pa6) and poly(ethylene-co-1-butene)-graft-maleic anhydride (eb-g-mah) blends have been prepared via melt mixing. the effect of blend ratio and organoclay concentration onthe crystallization and melting behavior of specimens were studied. three types of commercial organo-modifiedclay (cloisite 30b, cloisite 15a and cloisite 20a) were employed to assess the im...

polyamide 6 has been widely used in food packaging applications and also green tea contains amounts of antioxidant compounds. the aim of this study was investigation of green tea effects on properties of polyamide packaging polymer. polyamide 6 was dissolved in methanol which was saturated with calcium chloride. the active packaging film was produced by incorporation of methanol green tea extra...

Internal forces such as managers with strategic intelligence and staff with entrepreneurial behaviour have forced organizations to constantly monitor their surrounding environment in order to create an awareness of opportunities and threats to allow them to survive in the competitive environment. Therefore, the main purpose of this paper is to investigate the relationship between strategic ...
