The Drosophila ovarian tumor gene (otu) encodes cytoplasmic proteins that are required in germ-line cells for cyst formation, nurse cell chromosome structure and egg maturation. We have analyzed a gene, fs(2)cup, that participates in many of the same processes and interacts with otu genetically. Both nurse cell and oocyte chromosomes require cup to attain a normal morphology. In addition, the g...

Cup experiments are the most widely used method to measure water vapor permeability of porous building materials. For this test, cup assembly is designed create a pressure gradient across sample and, thus, allow diffusion through it. Water assessed by weighing over time. While external conditions generally well controlled, appropriate solid desiccants or saturated salt solutions control inside ...

Biodegradation of polythene bags and plastic cups was analyzed after 2, 4, 6, and 9 months of incubation in the mangrove soil. The biodegradation of polythene bags was significantly higher (up to 4.21% in 9 months) than that of plastic cups (up to 0.25% in 9 months). Microbial counts in the degrading materials were recorded up to 79.67 x 104 per gram for total heterotrophic bacteria, and up to ...

OBJECTIVES After total hip arthroplasty (THA), restoration of hip center of rotation (COR) is essential to ensure stability of the prosthetic hip and longevity of the prosthesis. Our aim was to determine whether, and how, the COR changed postoperatively compared to the native COR following implantation of a cementless acetabular component in anatomical position and to compare the accuracy of cu...

The cup method is applied for the measurement of water vapor transport properties of porous materials worldwide. However, in practical applications the experimental results are often used without taking into account some secondary effects which can play an important role under specific conditions. In this paper, the effect of temperature on water vapor transport properties of cellular concrete ...

OBJECTIVES To evaluate the optic disc area and cup area in a normal population over 40 years of age. MATERIALS AND METHODS This prospective study was performed in Eskişehir. Fundus photographs were obtained using a nonmydriatic fundus camera. Planimetric measurements of the optic disc and cup area were performed with VK-2 digital imaging software. Optic nerve parameters were then compared bet...

BACKGROUND AND PURPOSE Adequate depth of cement penetration and cement mantle thickness is important for the durability of cemented cups. A flanged cup, as opposed to unflanged, has been suggested to give a more uniform cement mantle and superior cement pressurization, thus improving the depth of cement penetration. This hypothesis was tested experimentally. MATERIALS AND METHODS The same cup...

BACKGROUND Cancer in pregnancy is a rare disease with breast cancer, cervical cancer, melanoma and Hodgkin's disease to be the most commonly diagnosed malignancies during gestation. Cancer of unknown primary (CUP) is a well-recognized clinical disorder where the primary site can not be identified after a standard diagnostic approach. CUP in pregnancy has rarely been described. MATERIALS AND M...

Leaking in water pipe is a critical issue in Middle Eastern countries such as Kuwait where water is scarce. In-pipe robots can be dispatched to discover the network and inspect the inner surface of the pipe. This thesis describes the design and characterization of suction pads for in-pipe robots. The suction cups are made of hyperelastic materials that contain air channels inside. Instead of us...
