OBJECTIVE To compare the acceptability, efficacy, adverse effects, and user satisfaction of the levonorgestrel intrauterine system (LNG-IUS) and trans-cervical resection of the endometrium (TCRE) for the treatment of menorrhagia. METHOD 104 women with menorrhagia were divided into 2 groups: 52 women had the LNG-IUS inserted and 52 underwent TCRE. Menstrual pattern, pictorial blood loss assess...
BACKGROUND Progestin-only methods are among the contraceptive options available for breastfeeding women, however the doses of progestin used in emergency contraception (EC) have not been evaluated in nursing mothers. We therefore investigated the pharmacokinetics of 1.5 mg levonorgestrel (LNG) in lactating women. METHODS Twelve healthy exclusively breastfeeding volunteers received 1.5 mg LNG....
تأسیس مجمع کشورهای صادرکنندة گاز در سال 2001 در تهران بدون شک از کلیدی‌ترین وقایع سال‌های اخیر در صنعت گاز است. بخش درخور توجهی از صادرات کشورهای عضو مجمع به صورت LNG است؛ از این‌رو، تدوین سیاستی مبتنی بر همکاری بین کشورهای عضو در عرصة صادرات LNG اهمیت و نقش بسزایی خواهد داشت. شواهد دلالت بر آن دارد که الگوی صادرات LNG کشورهای عضو مجمع غیربهینه و غیراقتصادی است. از این‌رو در این مقاله نخست، وضع...
We develop LNG FEM, a software package for graded mesh generation and for solving elliptic equations. LNG FEM generates user-specified graded meshes on arbitrary two-dimensional domains with straight edges, for different boundary conditions, once initial information is passed to the program by appropriately filling out some source files. We focus on a detailed instruction on the implementation ...
BACKGROUND This study was designed to evaluate the comparison of insertion of levonorgestrel (LNG)-releasing intrauterine system versus oral medroxyprogesterone acetate on endometrial hyperplasia in a randomized controlled trial. MATERIALS AND METHODS A total of 60 women with the initial histopathological diagnosis of endometrial hyperplasia in two groups received LNG or medroxyprogesterone (...
Liquid Natural Gas (LNG) processing facilities typically are located on ocean shores for easy transport of LNG by marine vessels. These plants use large quantities of water for various process streams. The combined wastewater effluents from the LNG plants are discharged to the coastal and marine environments typically through submarine outfalls. Proper disposal of effluents from an LNG plant is...
Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance costeffective technologies for operating and refueling natural gas–fueled hea...
 liquefied natural gas (LNG) is the most economical way of transporting natural gas (NG) over long distances. Liquefaction of NG by using vapor compression refrigeration system requires high operating and capital cost. Due to lack of systematic design methods for multistage refrigeration cycles, the conventional approaches of determining optimal cycle configuration are mostly based on trial-an...
BACKGROUND Heavy menstrual bleeding is an important health problem. Two frequently used therapies are the levonorgestrel intra-uterine system (LNG-IUS) and endometrial ablation. The LNG-IUS can be applied easily by the general practitioner, which saves costs, but has considerable failure rates. As an alternative, endometrial ablation is also very effective, but this treatment has to be performe...
In 2009, a series of experiments were conducted by Sandia National Laboratories at a large-scale test complex in Albuquerque, New Mexico, in which Liquefied Natural Gas (LNG) was released onto the surface of a large pool of water and then ignited. These experiments involved the largest releases of LNG ever performed, with the spills covering a circular area up to 83 m in diameter. In the test w...
