Abstract: Recent years, with the rapid development of world economy, energy consumption is sharply increaseing and the environment is deteriorating. Liquefied Natural Gas (LNG), a clean renewable energy which can be used as ship fuel, is drawing attentions from more and more countries over the world. However, the conversion of the LNG-diesel dual fuel engine (DFE) in China as a new research is ...

The purpose of this study was to evaluate trunk stability in seated elderly and young individuals using a new device that inclines a seat while tracking the center of pressure (CoP). We evaluated the locus of CoP, locus length, locus length per second, enveloped area, root mean square area, and locus length per unit area (LNG/AREA). LNG/AREA, which reflects postural adjustments controlled by th...

The valuation of the real option to store liquefied natural gas (LNG) at the downstream terminal of an LNG value chain is an important problem in practice. As the exact valuation of this real option is computationally intractable, we develop a novel and tractable heuristic model for its strategic valuation that integrates models of LNG shipping, natural gas price evolution, and inventory contro...

Sloshing problems in partially filled large LNG carriers are of increasing concern because sloshing loads may endanger LNG carriers in operations. Currently, most investigations on sloshing problems mainly focus on the analysis of liquids in rigid tanks which omitted fluid-structure interactions. Based on a mixed displacement–pressure finite element method developed, the authors recently invest...

OBJECTIVE To review the literature on usage of the levonorgestrel intrauterine system (LNG IUS) in women with fibroids or adenomyosis in an attempt to develop a pragmatic approach when faced with enlarged uteri. DATA SOURCES Computerised searches of MEDLINE and EMBASE up to December 2000. Some of the information was obtained from references listed in the primary sources and references already...

OBJECTIVE To compare the effectiveness and acceptability of LNG-IUD with oral progesterone (norethisterone acetate; NETA) in achieving a reduction in volume of the myomas, hemoglobin levels, satisfaction of the women. METHODS This study includes randomized 30 women treated by LNG-IUD and randomized 30 women treated by oral norethisterone (NETA). All these participants in the study have receiv...

THE PAPER PRESENTS THE RESULTS OF AN ANALYSIS FOCUSING ON the evaluation of large-scale oil and gas projects under market uncertainty and flexibility in engineering design. Keppel Offshore and Marine Technology Centre (KOMTech) has developed a proprietary Pre-cooled Nitrogen Expander (PreNex) technology as a solution for offshore associated gas applications for small-to-medium scale capacity (~...

BACKGROUND We aimed to evaluate the effect of the levonorgestrel-releasing intrauterine system (LNG-IUS) on the uterine vasculature and the endometrium. METHODS The study was a prospective controlled study evaluating the local effects of LNG-IUS compared with the copper intrauterine device (IUD). Forty-seven women carrying LNG-IUS (group A) were compared with 35 women carrying copper IUD in a...

My dissertation concentrates on several aspects of supply chain management and economic valuation of real options in the natural gas and liquefied natural gas (LNG) industry, including gas pipeline transportation, ocean LNG shipping logistics, and downstream storage. Chapter 1 briefly introduces the natural gas and LNG industries, and the topics studied in this thesis. Chapter 2 studies how to ...

BACKGROUND Repeated use of postcoital hormonal contraception is not currently recommended due to the higher risk of side effects and lower contraceptive effectiveness compared to other modern methods of contraception. However, emerging evidence indicates renewed interest in a regular coitally-dependent method of oral contraception. We re-evaluated the existing data on safety and effectiveness o...
