Abstract: The present study deals the theoretical modeling aspects of coupled conductive and radiative heat transfer in the presence of absorbing, emitting and scattering gray medium within two-dimensional square furnace including two flames. The gray radiative medium is bounded by isothermal walls which are considered to be opaque, diffuse and gray. The well known discrete ordinate method (DOM...

Background: Jaw bone quality plays an essential role in treatment planning and prognosis of dental implants. Regarding several available methods for bone density measurements, they are not routinely used before implant surgery due to hard accessibility.Objective: An in vitro investigation of correlation between average gray scale in direct digital radiographs and Hounsfield units in CT-Scan pro...

background: volume estimation of brain is important for many neurological applications. it is necessary in measuring brain growth and changes in brain in normal/abnormal patients. thus, accurate brain volume measurement is very important. magnetic resonance imaging (mri) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. st...

Abstract Platform works are swiftly turning into a big, perhaps game-changing force in the labor market. From low-skilled, low-paid services (like passenger transport) to high-skilled, high-paying project-based developing artificial intelligence algorithms), digital platforms can handle wide range of tasks. Our paper discusses platform-based content, working conditions, employment status, and a...

BACKGROUND It has been suggested that differences in health technology assessment (HTA) processes among countries, particularly within Europe, have led to inequity in patient access to new medicines. OBJECTIVES To provide an up-to-date snapshot analysis of the present status of HTA and reimbursement systems in select European countries, and to investigate the implications of these processes, ...

Monitoring studying informal, gray, parallel, hidden relations in domicile continues to attract undiminished attention economists, lawyers, sociologists, criminologists, ...

in this study, the vertical, transverse and oblique diameters of the spinal cord segments (c1, c6, c12, c18, t1, t4, l1, l4, l6 and l8) and the ratio of gray matter to white matter in chick (l month) and adult (18 months) male ostriches, each group consisted of 3 animals, were measured with standard micrometric method using 6 μm thick sections by light microscope. with advancement of age, the r...
