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...

BACKGROUND The levonorgestrel-releasing intrauterine system (LNG-IUS) is an effective contraceptive and has many non-contraceptive health benefits. However, it is commonly associated with irregular endometrial bleeding. Metalloproteinases contribute to extracellular matrix (ECM) remodelling and regulate bleeding during the menstrual cycle. Enhanced metalloproteinase expression participates in t...

At present, throughout the world LNG investments are abounding. In particular, the US and the EU are trying to facilitate their security of natural gas supply. For this reason, LNG enables importers to extend their gas suppliers’ portfolio, considering that some producing countries can be reached only via sea transport. LNG will thus increase importers’ choice; at the same time it can widen the...

OBJECTIVES The UK Faculty of Sexual & Reproductive Healthcare (FSRH) has recommended that for emergency contraception (EC) the health professional should discuss individual needs and inform women of the different methods, efficacy, adverse effects, interactions, eligibility and additional contraception. In our sexual and reproductive health care service (Liverpool and Knowsley, UK), revised gui...

BACKGROUND Consecutive use of the levonorgestrel-releasing intrauterine system (LNG-IUS) is increasing. However, little is known about factors that predict the bleeding during consecutive use. The objective of this study was to analyse the possible factors which may predict the bleeding pattern during the first year of use of a second LNG-IUS. METHODS Fertile-aged women (n = 204) who had used...

AIMS This study aimed to investigate whether cabotegravir (CAB), an integrase inhibitor in development for treatment and prevention of human immunodeficiency virus-1, influences the pharmacokinetics (PK) of a levonorgestrel (LNG) and ethinyl oestradiol (EO)-containing oral contraceptive (OC) in healthy women. METHODS In this open-label, fixed-sequence crossover study, healthy female subjects ...

This paper presents a generic, high-level risk assessment of the global operation of ocean-going liquefied natural gas (LNG) carriers. The analysis collects and combines information from several sources such as an initial hazid, a thorough review of historic LNG accidents, review of previous studies, published damage statistics and expert judgement, and develops modular risk models for critical...
