FOOD ALLERGENS - PRESENCE, RISKS AND MANAGEMENT IN FOOD INDUSTRY

Food allergy is a reaction of the body immune system to the presence of the proteins in the body introduced through food. Allergic reactions can affect the skin (hives), gastrointestinal organs (nausea, cramps, diarrhea), respiratory system (attenuation) and circulation (drop in blood pressure). In extreme cases, anaphylaxis can occur.. In this cas...

THERMAL AGING STUDY OF BIODEGRADABLE POLYMER MATERIALS BY DIELECTRIC THERMAL ANALYSIS

Two different studies of the thermal aging of polyesters based on lactic and glycolic acidswere compared. Thermal degradation of poly(L-lactic acid) (PLLA), poly(L-lactic acid-co-glycolicacid) (PLLGA) and poly(DL-lactic acid-co-glycolic acid) (PDLGA) was studied by the dielectricthermal analysis (DETA). The aging was performed at 37C in vacuum ove...

USE OF FLY ASH IN ROADS BUILDING

Fly ash is useful for a variety of applications, because it is a plaster or silicate or aluminosilicate material which is in an isolated form and in the presence of water is combined with calcium hydroxide (from lime, portland cement or dust from furnaces) and formed mixtures with the characteristics of the binder. In this project analyzed the poss...
