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...

Women need multipurpose prevention products (MPTs) that protect against sexually transmitted infections (STIs) and provide contraception. The Population Council has developed a prototype intravaginal ring (IVR) releasing the non-nucleoside reverse transcriptase inhibitor (NNRTI) MIV-150 (M), zinc acetate (ZA), carrageenan (CG) and levonorgestrel (LNG) (MZCL IVR) to protect against HIV, HSV-2, H...

The levonorgestrel-releasing intrauterine system (LNG-IUS), originally designed for contraception, has since been applied to various gynecologic diseases. This article summarizes the current status of clinical applications of LNG-IUS to the treatment of gynecologic diseases such as heavy menstrual bleeding, endometriosis, leiomyoma, adenomyosis, endometrial hyperplasia, and early-stage endometr...

Gas prices around the world vary widely despite being connected by international trade of liquefied natural gas (LNG). Some industry observers argue that major exporters have acted irrationally by not arbitraging prices. This is also diffi cult to reconcile with a competitive model in which regional price differences exist solely because of transport costs. We show that a model which incorporat...
