I n 1925, Gershenson started laboratory cultures from 19 female Drosophila obscura that were collected from a forest near Moscow. After recounting his difficulties raising the flies (partial success achieved with a diet of potatoes and fermented raisins), he noted that progeny from most cultures contained an approximately equal sex ratio [1]. Several cultures, however, yielded progeny with high...

Introduction: In this study, a computer analysis method based on a block matching algorithm is presented to extract the longitudinal movement of the carotid artery wall using consecutive ultrasonic images. A window (block) is selected as the reference block in the first frame and the most similar block to the reference one is found in the subsequent frames. Material and Methods: The program was...

The comparison of building energy efficiency in different climates is a growing issue. Unique structural solutions will not ensure the same use, but differences also remain if cost-optimal are applied. This study developed new equation for assessment envelope optimal insulation office buildings. method suggests determining actual degree days from simulated heating need and thermal conductance b...

Introduction: In nuclear medicine imaging, detection of the scattered photons along with the primary photons is one of the major problems that can lead to a decrease in ddiagnostic accuracy. Therefore, use of a suitable scatter correction method can help to improve of the image quality and increase of diagnostic accuracy. The aim of this study is evaluation of five energy wind...

The building envelope includes all materials (glazing, external walls, doors, etc.) that separate the conditioned space from outside environment. Building characteristics significantly influence energy consumption of buildings. In this study, research was carried out to find optimum design parameters, such as insulation thickness, orientation, glazing type, and window-to-wall ratio a room, usin...

This Letter features a new, scalable fabrication method and experimental characterization of glass-filled apertures exhibiting extraordinary transmission. These apertures are fabricated with sizes, aspect ratios, shapes, and side-wall profiles previously impossible to create. The fabrication method presented utilizes top-down lithography to etch silicon nanostructures. These nanostructures are ...
