objective: recently the laparoscopic ovarian drilling (lod) has been used as a surgical treatment for ovulation in women with polycystic ovarian syndrome (pcos), although its mechanism and outcomes are still unclear. this study was undertaken to evaluate the in vitro fertilization (ivf)/intracytoplasmic sperm injection (icsi) outcomes in clomiphene-resistant women with pcos who were treated wit...

A major drawback of directional and horizontal well drilling is the numerous complex computations required to be done while planning a well. These computations are very stressful and time consuming especially when done manually. One of the objectives of this study was to develop a user friendly Excel Spreadsheet program that would make the computations of these well trajectory parameters easier...

BACKGROUND The effects of ovarian drilling on the serum levels of gonadotropins and androgens have been studied previously. The aim of this study is to evaluate the effects of ovarian drilling on the serum prolactin levels and its relation to ovulation in women with polycystic ovary syndrome. METHODS This is a prospective controlled study. Thirty-six women with PCOS underwent ovarian electroc...

The correct placement of a retrograde nail for fixation in a combined ankle and subtalar arthrodesis especially in the presence of deformity be difficult.2–4 We have previously introduced a 2D imaging-based CAS guided drilling for nail placement.6,7 The 2D imaging-based CAS guided correction positioned the calcaneus in relation to the talus and/or the tibia.6,7 Due to difficulties in planning a...

Sub-Surface Drilling is the process of making boreholes into the Earth, which can reach depths of many kilometers. One of the major purposes of such boreholes is the exploration of oil or gas bearing formations with the goal to recover the content of such reservoirs. Problems in drilling operations pose serious risks for the crew and the environment and can cause significant financial losses. C...

Navigating through multidimensional data cubes is a nontrivial task. Although On-Line Analytical Processing (OLAP) provides the capability to view multidimensional data through rollup, drill-down, and slicing-dicing, it offers minimal guidance to end users in the actual knowledge discovery process. In this article, we address this knowledge discovery problem by identifying novel and useful patt...

For the past three decades the quantity of petroleum (both oil and oil plus gas) found per foot of drilling effort in the United States for any given year can be expressed as a secular decrease of about 2 percent per year combined with an inverse function of drilling effort for that year. Extrapolation of energy costs and gains from petroleum drilling and extraction indicates that drilling for ...
