Accounts of mad honey intoxication date back to 401 BC. It is still one of the common food intoxications encountered for humans(More)
PURPOSE This study reports the feasibility of the symmetric fields for the usage of asymmetric fields, and checks the accuracy of treatment planning system (TPS). MATERIALS AND METHODS A GE Saturne-42 linear accelerator, which produces dual photon energies of 6 and 15 MV, and an ISIS-3D TPS were used in this study. Percent depth doses (PDDs), dose(More)
A numerical study has been carried out on partially heated triangular enclosures with eave. The eave and inclined wall has a cold temperature. The laminar, two-dimensional, steady governing equations of natural convection are solved in the streamfunction-vorticity form using a finite difference technique. Streamline, isotherm and Nusselt number are(More)
Wild plants are important in terms of human nutrition and folk medicine in Turkey. Especially the ones collected from rural areas and sold in the market are rich sources of dietary fiber important for human health. In this study, the dietary fiber contents of 13 different plants consumed frequently were determined by enzymatic-gravimetric method. The lowest(More)
BACKGROUND The influence of cooking (traditional, microwave, autoclave) and drying techniques (microwave and hot air) on bioactive compounds in the production of einkorn and durum bulgur were investigated. Total phenolic content (TPC), total yellow pigment (TYP), total antioxidant capacity (DPPH• , ABTS•+ , FRAP), soluble free (SF), soluble conjugated (SC)(More)
