Current interest in the shipment of liquefied natural gas (LNG) has renewed the debate about the safety of shipping large volumes of flammable fuels. The size of a spreading pool following a release of LNG from an LNG tank ship has been the subject of numerous papers and studies dating back to the mid-1970s. Several papers have presented idealized views of how the LNG would be released and spre...

CYP2G1 is a cytochrome P450 monooxygenase expressed uniquely in the olfactory mucosa (OM). We have generated Cyp2g1-null mice to identify the roles of CYP2G1 in the biology and the tissue-specific toxicity of xenobiotic compounds in the nose. Homozygous Cyp2g1-null mice are viable and fertile; they show no evidence of embryonic lethality, morphological abnormality, or developmental deficits; an...

regarding the recent development in lng production and transportation, lng exports would exhibit a pivotal role in the future of global gas trade. by analyzing the geographical pattern of the world lng trade and the structure of its transportation costs, the lng cost matrix for forum's exporters to main lng importers is presented. using this matrix, the cooperation amongst the forum's...

OBJECTIVES To calculate the cost of an unintended pregnancy in 2011 and use this cost in a cost-effectiveness model comparing ulipristal acetate (UPA) with levonorgestrel (LNG) for emergency hormonal contraception (EHC). DESIGN Retrospective analysis of published data sources and published cost-effectiveness model. SETTING Women presenting in primary care in England for EHC within 24 or 72 ...

To identify novel factors or mechanisms that are important for the resistance of tissues to chemical toxicity, we have determined the mechanisms underlying the previously observed increases in resistance to acetaminophen (APAP) toxicity in the lateral nasal gland (LNG) of the male Cyp2g1-null/Cyp2a5-low mouse. Initial studies established that Cyp2a5-null mice, but not a newly generated strain o...

OBJECTIVE To compare hysterectomy and levonorgestrel intra-uterine system (LNG-IUS) for the treatment of abnormal uterine bleeding (AUB) and iron deficiency anemia. PATIENTS AND METHODS Retrospective study evaluating quality of life, sexual function, satisfaction and blood hemoglobin concentration improvement in 60 pre-menopausal women treated with hysterectomy or LNG-IUS. All analysis was pe...

The primary operational objective of liquefied natural gas (LNG) plants with low production capacity is to maximize LNG production. A robust control structure is required to meet economic objective while ensuring safety of the plant. The selection of appropriate controlled variables (CVs) is critical for design of the control structure. In this paper, general process understanding and the conce...

(EH) is a common disease affecting women of all ages [1]. It is clinically important because it can cause abnormal uterine bleeding, and can precede, or occur concurrently, with endometrial carcinoma. There are many progestin therapy regimens available for treatment of EH. The main progestational agents are oral pro-gestogens such as norethisterone acetate, megestrol acetate, and medroxyprogest...

BACKGROUND The purpose of this study was to provide additional data on the experience with frameless copper and levonorgestrel (LNG) intrauterine devices (IUDs) in nulliparous and adolescent women. METHODS Nulliparous and adolescent women, 25 years of age or younger, using the frameless copper IUD or the frameless LNG-releasing intrauterine system (IUS), were selected from previous studies an...

The purpose of this paper is to develop a methodology to evaluate the feasibility of using landfill gas (LFG) as a liquefied natural gas (LNG) fuel source for heavy-duty refuse trucks operating on landfills. Using LFG as a vehicle fuel can make the landfills more self-sustaining, reduce their dependence on fossil fuels, and reduce emissions and greenhouse gases. Acrion Technologies Inc. in asso...
