Owing to ever increasing share of the natural gas in the world consumption of the power sources, the international maritime traffic with the liquefied gas is recording constant growth with even greater future anticipations. It results in the need for the construction of new LNG receiving terminals. In order to be integrated in those trends and to make provisions for additional quantities of pow...

Findings: In the literature, the mechanisms of action of LNG-IUS as a contraceptive include impairment of sperm transport through the cervix due to thick cervical mucus and through the uterus due to inflammatory changes in the endometrium affecting sperm transport and function, and possibly fertilisation and implantation are impaired. The evidence from the literature shows that following long-t...

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...

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...

In operation of a large LNG processing plant there will be uncertainties related to planning and realization of an optimal operation strategy. Results show the importance of including the whole production chain in the optimization. For a test scenario where we look at the event of delayed ship arrival, this gives lower losses than a normal approach where the upstream part of the system and the ...

Liquefied Natural Gas (LNG) is steadily becoming a common mode for commercializing natural gas. In this paper, we develop methods for improving both lower and upper bounds for a previously stated form of an LNG inventory routing problem. A Dantzig-Wolfe-based decomposition approach is developed for LNG inventory routing problem (LNG-IRP) attempting to overcome poor lower bounds. However, it fai...

In order to control their release, drugs are encapsulated into systems which are expected to provide a certain site with a predetermined amount of drug over a well-defined period of time. Here we report on a multi-component drug delivery biomaterial that consists of a hydrogel matrix in which drug-loaded biodegradable microcarriers are dispersed, and whose potential applications could be found ...

Simple, accurate and precise Zero order, first derivative spectrophotometric and chromatographic methods have been developed and validated for the determination of linagliptin (LNG) and metformin HCl (MET). The zero order and first derivative spectrophotometric methods were used for the determination of LNG in the range of 5-30 μg mL(-1) by measuring the absorbance at 299 nm and 311 respectivel...

Thermal efficiency is a common benchmark used to compare competing processes when a new LNG project is being developed. Often this type of comparison can be misleading when used in isolation because plant design premises are not consistent from project to project. Thermal efficiency depends on numerous issues such as gas composition, inlet pressure and temperature, and even more obscure issues ...

This feasibility study is a response to the increasing of interest in coal seam gas (CSG) in Australia and due to the demands for alternative fuels by high fuel-consumption industries such as agriculture. A technical analysis of LNG as an alternative fuel to diesel in agriculture was conducted. A comparison of different conversion methods (dual-fuel and mono-gas systems) is undertaken. Data was...
