Optimization Of The Ground For Cab 6p (Prunus Cerasus), Avdirrahman Gashi, Sami Gashi, Taulant Mitrushi, Edlira Kukali

UBT International Conference

Rooting is a process that is induced by many difficulties, especially in fruit trees. For this reason, four nutrient terrains that contain different concentrations of auxin ANA (α-naphthaleneacetic acid), BAP, GA3 and macro and micronutrient MSs are compared. Rizogenesis is observed after three to four weeks of cultivation on the ground of rupture. Explants react differently in each field used (Figures 4,5,6,7). The concentration of inorganic and auxinous ANA salts on the nutrient terrains affects the rooting index and the characteristics of the roots. Plants of the prunus cerasium L species showed better results during rooting cultivation I, where the …

Interaction Of Nanofibers With Epithelial Cells In The Digestive System, Agron Millaku

UBT International Conference

In this study, we provide the evidence of interaction of tungsten nanofibres (NF- WOx) with epithelial cells in the digestive tube of a test organism, woodlouse Porcellio Scaber studied by scanning electron microscopy (SEM). When the nanofibers enter the body through food, not all of them pass through the digestive system, without an interaction with the epithelial cells. The result has provided us that in some areas nanofibers can react with epithelial cells on the digestive tube very fast. The images which were taken in the treated samples through scanning electron microscopy and energy dispersive spectroscopy analysis clearly show such …

Genealogical Analysis Of Bar’S Body Activity In Hemophilia At Two Brothers And A Cousin, Naser Kamberi

UBT International Conference

In this study it is included a sample of the Presevo population and villages of 3771 individuals. During family interviews, we encountered cases in women with hemophilia and hemophiliacs. Predicting that X-sex chromosome is inactive we did not have the case that females are hemophilic. By doing the genealogical analysis of these families, we will present the thoughts about the role of Bari's body when it comes to hemophilia. The genealogical method can be used especially effective in cases of monogenic inheritance. From the cases encountered during the hearing, we did not have any hemophilia in female gender. Considering that …

The microbiological quality of raw milk is key to the quality production of dairy products.

Alternation is a term that describes the change of composition, taste and smell at those points where it is inedible for the consumer. Microbial alternation of milk often involves degradation of proteins, carbohydrates and fats of organisms and their enzymes. Milk and dairy consumption has increased considerably in Kosovo over the last decade, and a large part of local productioncomes from small-scale distributors across the country. In this research, 50 milk samples weretaken at some of the cumulative sites and from dairy farms in three …
