The present study investigated the degradation of levonorgestrel (LNG) and gestodene (GES) through an anodic oxidation process mediated by active chlorine species. independent variables [LNG]0 [GES]0, current density (mA cm?2), [NaCl]0 (mol L?1) were optimized a response surface methodology (RSM) based on four-level central composite design (CCD). Specific energy consumption allowed CCD-RSM ana...

A composition stream from reservoir to the market has been obtained as a result of upstream, midstream and downstream retrograde gas-condensate models integration. Applications are composition, Peng-Robinson EOS has been chosen as a fluid package. Different production scenarios were observed to define development strategy for rich gas condensate production. VGD and C/V gas drive mechanisms have...

the levonorgestrel-releasing intrauterine system We write to report a recent European survey of factors that motivate women to use or reject the levonorgestrel-releasing intrauterine system (LNG-IUS). The survey comprised focus group sessions to identify barriers that prevent women using the LNG-IUS and individual interviews with current users to identify their reasons for having chosen the LNG...

In Indonesia, the CoS for power supply increased from Rp. 1025 to 1334/KWh 2016 2021, respectively; this indicates an inefficient process in electricity provision. One contributing factor inefficiency is existence of many high speed diesel (HSD)-fueled plants. These are distributed across Indonesian archipelago with a chain that only uses sea transportation. The absence economical small-scale L...

IUD) is thought to act immediately by inhibiting sperm and ovum viability or preventing implantation.2 The LNG-IUS has a different contraceptive mechanism of action that relies on hormonal effects on the endometrium, cervical mucus and uterotubal transport, and thus has a delayed onset.2,3 This is the rationale for advising additional contraception for 7 days if a LNG-IUS is inserted after Day ...

BACKGROUND Electrospun drug-eluting fabrics have enormous potential for the delivery of physicochemically diverse drugs in combination by controlling the underlying material chemistry and fabric microarchitecture. However, the rationale for formulating drugs at high drug loading in the same or separate fibers is unknown but has important implications for product development and clinical applica...

OBJECTIVE The purpose of this study was to investigate if the levonorgestrel-impregnated intrauterine device (LNG-IUS, Mirena(®) ) is safe and effective as therapy for low-risk and medium-risk endometrial hyperplasia compared with oral medroxyprogesterone (MPA). DESIGN A multicentre randomised trial. SETTING Norway. POPULATION In all, 170 women aged 30-70 years with low- or medium-risk en...

Compressor performance for liquefied natural gas (LNG) main refrigeration units is very important due to the direct link between compressor efficiency and LNG production for a fixed amount of power. Dresser-Rand recently designed a series of new stages for the LNG market that provided improved efficiency and a wider range of operation. Industry practice is to rig test new stages prior to applic...

Since the 2004 guidance report by Sandia National Laboratories [1], the use of computational fluid dynamics (CFD) models to simulate LNG vapor dispersion scenarios has been growing steadily, with applications to LNG spills on land as well as on water. Before a CFD model may be applied to predict the vapor dispersion hazard distances for a hypothetical LNG spill scenario, it is necessary for the...
