Background: A first quality of life (QOL) study among Maltese adults with congenital heart disease (ACHD) in 2016 found no significant differences when compared to the general population. The aims of the present study were to (1) compare QOL between Maltese and other European ACHD patients and (2) investigate medical predictors (i.e. number of surgical/non-surgical interventions, heart failure, arrhythmias, pacemaker/implantable cardioverter-defibrillator, cardiac hospitalisation during preceding year, follow-up frequency, other medical conditions, mood/anxiety/psychiatric disorders) of QOL in Maltese patients.Methods: Data collected during “Assessment of Patterns of Patient-Reported Outcomes in Adults with Congenital Heart disease–International Study” (APPROACH-IS) was used. QOL was measured using linear analog scale (LAS) and Satisfaction With Life Scale (SWLS). QOL in 109 Maltese and 1510 European participants was compared. Multivariable logistic regression was used to test the predictive value of medical factors on QOL in Maltese patients.Results: There were no significant differences in QOL between the two cohorts [mean LAS Malta 80.51 (95% CI 77.96,83.07) vs. European 79.43 (95% CI 78.65,80.21) (p=0.776); mean SWLS Malta 26.00 (95% CI 24.94,27.06) vs. European 26.26 (95% CI 25.95,26.57) (p=0.288)] and no significant differences when cohorts were divided by gender and age. Only a mood/anxiety/other psychiatric disorder significantly predicted poorer QOL on both scales in Maltese patients (LAS (ß=-.389, p<0.001), SWLS (ß=-.352, p=0.001)). Conclusions: Maltese ACHD patients have a good QOL comparable to that of European counterparts. Mood, anxiety and other psychiatric disorders can negatively impact Maltese patients’ QOL. Better access to clinical psychology services should be ensured.
Fighting bacterial resistance: approaches, challenges, and opportunities in the search for new antibiotics.Part 1. Antibiotics used in clinical practice: mechanisms of action and the development of bacterial resistance
Authors: Zhivich Alexander 
Published: February 2018

ABSTRACT
Hundreds of thousands of people are dying every year in the world from infections caused by drug resistant bacteria. Antibiotic resistance is a rapidly increasing problem mostly as a result of the worldwide overuse and misuse of antibiotics for conditions that do not require them. The rapid spread of antibiotic resistance in bacteria makes it necessary to intensify the development of new antibiotics and new methods to combat drug resistant bacteria. The goal of this publication is to review the approaches to finding new antibiotics that are active against drug resistant bacteria. The first part of this review is focused on an analysis of the mechanisms of action of antibiotics that are used in clinical practice as well as the mechanisms of bacterial resistance. The molecular structure and modes of action of these antibiotics are reviewed with examples of detailed mechanisms of drugs interaction with the targets in bacteria. General and specific mechanisms of bacterial resistance to these antibiotics are described. Examples of new antibiotics development active against the drug resistant bacteria are presented.

<p>Cocoa has become one of the strategic export commodities which accounted for the fourth largest foreign exchange after oil palm, rubber, and coconut. Indonesian cocoa production is significantly increasing, but the quality is still unsatisfactory. This will give conveying pathern of low quality of Indonesian cocoa in international markets. The producers need to improve the cocoa beans quality and start selling intermediate to final processed product. The fermentation process is an essensial stage of cocoa beans processing to guarantee a good flavor and aroma. Pressing process is also a very important step of process in determining the quality of cocoa.This research was aimed to determine the influence of cocoa liquefied temperature on the fat yield and fat content of the cocoa powder obtained from pressing of cocoa paste with a hydraulic pressing system. The result of this study is expected to provide information on the effectiveness of pressing at several cocoa paste temperatures. The treatments was arranged in Factorial Designwith 3 treatments of cocoa paste temperature (room temperature (± 30<sup>o</sup>C), 40<sup>o</sup>C and 50<sup>o</sup>C), and 3 replication for fermented and without fermentation cocoa. The results of this study show that effective temperature on compression of paste is at a temperature of 50 <sup>o</sup>C which generated the most fat yield and the lowest fat content of cocoa powder.</p><p> </p><p><strong>PENGARUH SUHU PEMASTAAN TERHADAP RENDEMEN DAN KADAR LEMAK BUBUK KAKAO HASIL PENGEMPAAN DARI BIJI KAKAO FERMENTASI DAN NON FERMENTASI</strong></p><p>Kakao telah menjadi salah satu komoditas ekspor strategis yang menyumbang devisa negara terbesar keempat setelah kelapa sawit, karet, dan kelapa.

Summary
Digital oil, a realistic molecular model of crude oil for a target reservoir, opens a new door to understand properties of crude oil under a wide range of thermodynamic conditions. In this study, we constructed a digital oil to model a light crude oil using analytical experiments after separating the light crude oil into gas, light and heavy fractions, and asphaltenes. The gas and light fractions were analyzed by gas chromatography (GC), and 105 kinds of molecules, including normal alkanes, isoalkanes, naphthenes, alkylbenzenes, and polyaromatics (with a maximum of three aromatic rings), were directly identified. The heavy fraction and asphaltenes were analyzed by elemental analysis, molecular-weight (MW) measurement with gel-permeation chromatography (GPC), and hydrogen and carbon nuclear-magnetic-resonance (NMR) spectroscopy, and represented by the quantitative molecular-representation method, which provides a mixture model imitating distributions of the crude-oil sample. Because of the low weight concentration of asphaltenes in the light crude oil (approximately 0.1 wt%), the digital oil model was constructed by mixing the gas, light-, and heavy-fraction models. To confirm the validity of the digital oil, density and viscosity were calculated over a wide range of pressures at the reservoir temperature by molecular-dynamics (MD) simulations. Because only experimental data for the liquid phase were available, we predicted the liquid components of the digital oil at pressures lower than 16.3 MPa (i.e., the bubblepoint pressure) by flash calculation, and calculated the liquid density by MD simulation. The calculated densities coincided with the experimental values at all pressures in the range from 0.1 to 29.5 MPa. We calculated the viscosity of the liquid phase at the same pressures by two independent methods. The calculated viscosities were in good agreement with each other. Moreover, the viscosity change with pressure was consistent with the experimental data. As a step for application of digital oil to predict asphaltene-precipitation risk, we calculated dimerization free energy of asphaltenes (which we regarded as asphaltene self-association energy) in the digital oil at the reservoir condition, using MD simulation with the umbrella sampling method. The calculated value is consistent with reported values used in phase-equilibrium calculation. Digital oil is a powerful tool to help us understand mechanisms of molecular-scale phenomena in oil reservoirs and solve problems in the upstream and downstream petroleum industry.
Revival of Green Conformance and IOR/EOR Technologies: Nanosilica Aided Silicate Systems - A Review
Authors: Lakatos I. , Lakatos-Szabo G. , Szentes G. 
Published: February 2018

Abstract
Reservoir conformance control (RCC) might be fundamental designingprofitable production technology in oilfields. Appropriate application of RCC methods can significantly results inimproved IOR/EOR throughreduced water production and profile correction. In the past decades, numerous techniques were extensively applied with these goals including macro- and microgels, emulsions, sols, crystalline compounds, etc. Surprisingly, the use of silicates was not really appreciated by the operators despite the fact that silicates were proposed for chemical EOR and profile control already in 1922. In the past decades, the silicate technology has a revival because of their outstanding features and these methods are superior to other gel technical solution. The review is summarizing both the old and the new results of laboratory research and the case histories. Recently, emblematic professionals proposed the silicate gels as efficient alternatives to other gel technologies. As a result, the attitude towards the extensive use of silicates in oil fields changed. Therefore, the presentation overviews the silicate conformance treatments and its advanced hybrid systems. They were used more than hundred times in Hungary, Serbia, Norway, USA, Oman, and other countries for water shutoff, profile correction, restriction of gas conning, mitigation of vertical CO2 migration in wells, remediation of leak-off by fractured casing, stimulation of wells operating in harsh environment, and mobility control in CO2 flooding.
The presentation summarizes the results of pilots and routine applications, and critically analyzes the lessons to learn. Base on the publications disseminated until now it can be concluded that the field jobs demonstrate outstanding statistics. It will also be shown that the diverse silicate RCC methods may attract attention because they can be efficiently used with high flexibility in all types of porous and fractured reservoirs. The in-situ formed silicate gels have excellent thermal stability up to 150°C, the chemicals are available at low price, the job needs simple surface facility, customary human force, and the methods are environmental friendly. Consequently, the silicate methods may open new vistas in brown field operations curing problems arising at oil and gas fields even in time of volatile oil and gas price.
Análisis multicriterio SIG basado en momentos de orden superior normalizados para el cálculo de superficies de viabilidad ambiental
Authors: Gómez Colorado Oscar Alberto , Horfán Álvarez Daniel , Londoño Ciro Libardo Antonio 
Published: February 2018

El presente estudio plantea una metodología para generar áreas de criticidad y niveles de susceptibilidad ambiental aptas para el trazado o localización de proyectos de infraestructura, con un alto grado de certidumbre comparado con los métodos convencionales basados en las funciones de máximos, media aritmética y promedio ponderado. La metodología se basa en la superposición espacial de variables físicas, ambientales y socioeconómicas que miden el impacto en el territorio ante el paso o ubicación del proyecto de infraestructura; aplicando el método de análisis estadístico denominado “momentos de orden superior” con un factor exponencial de normalización, propuesto por los autores. El modelo de análisis propuesto aplica principalmente en el Diagnóstico Ambiental de Alternativas (DAA) de proyectos lineales y concentrados, exigido por el Ministerio de Ambiente y Desarrollo Sostenible (MINAMBIENTE), en Colombia. El modelado espacial de los datos y las operaciones de superposición de capas de información, se realizaron a través de la herramienta Model Builder y la calculadora de mapas del software Arcgis. El análisis numérico y espacial realizado a través del SIG representa la interacción de los diferentes componentes bióticos, físicos y sociales (económicos, políticos y culturales), que inciden en la viabilidad del trazado o ubicación de un proyecto de infraestructura (vías, oleoductos, líneas de transmisión de energía, centrales hidroeléctricas, rellenos sanitarios, entre otros).Los resultados obtenidos demuestran como la superficie de susceptibilidad general, calculada con el método de momentos de orden superior normalizado, permite una toma de decisiones adecuada, toda vez que puede ajustarse con mayor aproximación a las diferentes restricciones ambientales de la región.
