BACKGROUND The main objective was to investigate if occurrence of hyperplastic polyps was reduced by use of the levonorgestrel-impregnated intrauterine system (LNG-IUS, Mirena®; Bayer) and if the LNG-IUS was more effective compared to oral medroxyprogesterone acetate (MPA) or observation-only. PATIENTS AND METHODS Patients (N=59) with hyperplastic polyps were given LNG-IUS, 10 mg oral MPA tak...

â 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...

CONTEXT Because menorrhagia is often a reason for seeking medical attention, it is important to consider outcomes and costs associated with alternative treatment modalities. Both the levonorgestrel-releasing intrauterine system (LNG-IUS) and hysterectomy have proven effective for treatment of menorrhagia but there are no long-term comparative studies measuring cost and quality of life. OBJECT...

OBJECTIVE The use of a levonorgestrel intrauterine system (LNG-IUS) is useful in preventing pregnancy and for the treatment of menstrual disturbances. A smooth or symptom-free transition to and through menopause is possible when LNG-IUS is combined with estrogen therapy. Unfortunately the majority of physicians are generally unaware of this usefulness combined hormonal therapy in the pre-, peri...

Considering the large amount of work that goes into the design of LNG processes, there is surprisingly little attention to their subsequent operation. This partly comes from the assumption that optimal design and optimal operation are the same, but this is not generally true. In this paper we study the optimal operation of a relatively simple LNG process, namely the PRICO process.

More rapid increases in the pH value and hardness during electromagnetic heating of a pan of water were observed than when the pan was heated by LNG or LPG. The water quality changed universally in several tap water samples across Japan. This quality change was closely correlated with the rate of temperature increase, irrespective of heating by electromagnetic induction, LNG or LPG.

STUDY QUESTION What is the risk of relapse for women with endometrial hyperplasia treated with levonorgestrel-releasing intrauterine system (LNG-IUS) or oral progestogens? SUMMARY ANSWER Relapse of complex endometrial hyperplasia after initial regression occurs often and it occurs less often in women treated with LNG-IUS than with oral progestogens. WHAT IS KNOWN ALREADY The LNG-IUS and ora...

The concept of using a frameless intrauterine device (IUD) instead of the conventional plastic framed IUD is not new. Frameless copper IUDs have been available since the late 1990s. They rely on an anchoring system to retain in the uterine cavity. The clinical experience with these IUDs suggests that frameless IUDs fit better as they are thin and, therefore, do not disturb or irritate the uteru...

OBJECTIVE To undertake an economic evaluation alongside the largest randomised controlled trial comparing Levonorgestrel-releasing intrauterine device ('LNG-IUS') and usual medical treatment for women with menorrhagia in primary care; and compare the cost-effectiveness findings using two alternative measures of quality of life. METHODS 571 women with menorrhagia from 63 UK centres were random...

this paper assesses the design guidelines of different classification codes for the liquefied natural gas carriers considering the effect of liquid sloshing. with regard the increasing importance of lng carriers in today’s marine transportation, and also considering that the marine accidents involve significant loss, classification societies by regulating national and international standards ai...
