Density Functional Theory Studies on New Possible Biobased Gemini Corrosion Inhibitors Derived from Fatty Hydrazide Derivatives.

Several new possible biobased corrosion inhibitors derived from fatty hydrazide derivatives were analyzed using quantum chemical calculations via the density functional theory method to investigate the chemical reactivity and inhibition efficiencies against corrosion in metal steel. The study confirmed that the fatty hydrazides showed significant inhibitive performances based on their electronic properties, revealing band gap energies of 5.20 to 7.

DFT Calculation and MD Simulation Studies on Gemini Surfactant Corrosion Inhibitor in Acetic Acid Media.

Gemini surfactant corrosion inhibitor (CI) is one type of CI mainly used in mitigating corrosion in the complex system of oil/gas production industries. Computer modeling methods such as density functional theory (DFT) calculation and molecular dynamic (MD) simulation are required to develop new CI molecules focusing on their application condition as a prediction or screening process before the physical empirical assessment. In this work, the adsorption inhibition efficiencies of two monomer surfactants (2B and H) and their respective Gemini structures with the addition of different spacers (alkyl, benzene, ester, ether, and ketone) are investigated using DFT calculation and MD simulation method in 3% sodium chloride (NaCl), and 1500 ppm acetic acid solutions.

Physio-Chemical Analysis of Amide and Amine Poly(dimethylsiloxane)-Modified Defoamer for Efficient Oil-Water Separation.

The formation of foam due to the injection of surfactant foam in FAWAG causes significant problems in the oil well production and separation facilities. The excessive foam can lead to the reduction of the separator capacity as well as its efficiency. A defoamer is needed to break and destroy the foam in the separator.

The political economy of health financing reform in Malaysia.

There is growing evidence that political economy factors are central to whether or not proposed health financing reforms are adopted, but there is little consensus about which political and institutional factors determine the fate of reform proposals. One set of scholars see the relative strength of interest groups in favour of and opposed to reform as the determining factor. An alternative literature identifies aspects of a country's political institutions-specifically the number and strength of formal 'veto gates' in the political decision-making process-as a key predictor of reform's prospects.

‘TAG, You’re It!’ The high-stakes game of handovers in the Emergency Department – Improving handover quality using a new ‘TAG’ Protocol.

Aim To assess handover quality amongst Emergency Department (ED) physicians and improve quality by implementing a unique protocol entitled ‘TAG, You’re It!’ (TAG protocol). Methods Patient charts assessed using set parameters prior to implementation of the ‘TAG’ protocol. ‘TAG’ protocol developed based on gaps in current practice and recommendations from literature.

Bacteraemia in the ED: Are We Meeting Targets?

Aim: An audit was performed in an Irish Emergency department (ED) to evaluate adherence to established antimicrobial guidelines and to determine the most common presentations of sepsis.

Methods: Data on ED patients with clinically significant bacteraemia on blood cultures were recorded for three months . The antimicrobial given to the patient was compared to that which the hospital guidelines would recommend for the ED diagnosis.

Identifying factors that influence the '6-hour target' in the Emergency Department by applying Regression Analysis.

Aim: To determine factors within the Emergency Department (ED) that have maximum influence on the '6-hour target'.

Methods: Regression Analysis methodology employed to analyse the influence of 9 ED variables on the '6-hour target' compliance.

Results: The number of patients waiting to be seen an ED physician at 8pm exerts maximum influence on the '6-hour target' (r = -0.

An unusual case of multiple self-inflicted punctures to the precordium.

Sewing needles, albeit a rare case of penetrating cardiac injury, are potentially life-threatening. We report a case of successful intra-cardiac needle removal from a 32 year old who inserted multiple needles into the chest and abdomen.

Social support perceptions of Turkish people with schizophrenia: What helps and what doesn't help.

Background: Social support is an important facilitator of the quality of life for people with schizophrenia. This study examines what is perceived as helpful and unhelpful support from the members of the natural social networks by 32 Turkish people with schizophrenia.

Material: Semi-structured interviews and thematic analysis were used to examine what is perceived as helpful and unhelpful support.
