Background: Lignocellulosic biomass has many functionalities that hold huge potential for material, energy or chemistry applications. To support advanced applications, the must be milled into ultrafine powder to increase reactivity. This milling unit operation needs fully mastered deliver high-quality standard end-products. Here we studied relationship between charac...

This study was performed to compare between two types of implant supported overdentures, with and without attachments. Methods: Fourteen completely edentulous patients received two implants in the canine region and loaded 3 months thereafter. Patients have been grouped into two groups; group Iconsisted of seven patients with two ball attachments and group II seven patients with support only (do...

We report successful surgical management of a 26-year-old man with a ball-shaped thrombus of the tricuspid valve. He had been treated with prednisolone for IgA nephropathy and undergone surgical closure of an isolated ventricular septal defect (VSD). No symptoms, coagulative disorders, or pulmonary embolisms were found. Preoperative echocardiography showed a ball-shaped mass that had originated...

One strategy for reducing the primary cesarean surgery rate and length of labor is using a peanut-shaped exercise ball for women laboring under epidural analgesia. A randomized, controlled study was conducted to determine whether use of a “peanut ball” decreased length of labor and increased the rate of vaginal birth. Women who used the peanut ball (n 5 107) versus those who did not (n 5 91) de...

This study was performed to evaluate the effect of using attachment on implant supported distal extension lower partial overdenture. Ten lower kennedy class II partially edentulous patients were selected to receive implant at second molar area, then patients were divided into 2 groups according to the implant superstructures either (dome shaped-or-ball and cap attachment). Patients of both grou...

This paper describes the experimental method for evaluating the flight trajectory and the aerodynamic performance of a kicked non-spinning soccer ball. The flight trajectory measurement is carried out using the digital image analysis. A centroid method and a template matching method are tested for the flight trajectory analysis using the artificial images generated by the data of a free-fall ex...
