Investigations, which are related to plasma efficiency on the treated leather surface, significant in development of ecologically and economically friendly processes obtaining material desired functional properties. Through pretreatments using different chemical-physical reactions surface layer occurred resulting improved reactivity. In this paper, modification functionalization bovine 1,2,3,4-...

Fruit leathers are dehydrated fruit products which are eaten as snacks or desserts. They are flexible sheets that have a concentrated fruit flavor and nutritional aspects. Most fruit leathers are prepared by mixing fruit puree and other additives like sugar, pectin, acid, glucose syrup, color, and potassium metabisulphite and then dehydrating them under specific conditions. Various drying syste...

The use of vegetable tannins is a bio-based alternative to chrome tanning. most used extracts are Mimosa and Quebracho. To improve the sustainability tanning process, chemically unmodified pine bark could be as natural source tannins. present study was aimed evaluate environmental impact powder obtain leather through life cycle assessment. Specifically, evaluation performed for both: i) tannin ...

BACKGROUND Although much is known about the natural history of systemic lupus erythematosus (SLE), the development of SLE autoantibodies before the diagnosis of the disease has not been extensively explored. We investigated the onset and progression of autoantibody development before the clinical diagnosis. METHODS The Department of Defense Serum Repository contains approximately 30 million s...

Full grain leather refers to the strongest and most durable part of cattle hide, consisting layer underlying corium, has not been sanded or buffed remove any imperfections, that means it displays more natural characteristics leather. Leather quality changes with sampling location, depending on variation present in fibrous structure. properties were also affected by tanning finishing processes u...

The dynamical mechanical analysis (DMA) technique was used for the characterization of some recently manufactured and historical parchments and leathers. The obtained results were correlated with the DSC measurements performed for these biomaterials. We point out the suitability of the DMA method for distinguishing qualitatively between a recently manufactured leather and a patrimonial one, as ...
