Authors: Ceric Anita , Sertic Josip 
Published: March 2019

Abstract
The purpose of this paper is to analyze how the Engineering Project Organization Society (EPOS) has addressed the issue of megaprojects at their annual conferences organized from 2006 to 2016. The literature analysis used in this paper is a form of content analysis. It focuses on the usage of a particular term in scientific papers. In this case, the key term is “megaprojects” or “mega-projects”. Papers in which this term appears are selected for further analysis. The findings show that the main keyword “megaproject” or “mega-project” appears 22 times in the identified papers. It appears in 10 titles and nine abstracts. Most important for this literature analysis, it appears in seven lists of keywords. Literature analysis proceeded by analyzing the associated keywords in the seven papers in which the main keyword “megaproject” or “mega-projects” can be found in the listed keywords. The analysis shows that the main associated keywords are “governance”, “complexity”, and “trust”. This research provides a view of the collective understanding of megaprojects within the EPOS community and helps to shape further research in this field. In addition, the results of this research can be seen as a step forward for scholars and practitioners to discuss and develop a new theoretical framework for better understanding of megaproject governance.

Published: March 2019

Risk stratification in elderly patients is very important, as none of the applied models for the prediction of mortality in cardiac surgery does not take into account the whole complex of physiological features of the aging organism.Theobjectivewas to analyze the effectiveness of the method of qualitative assessment of biological age.Material and methods.Our study included 127 patients (87 male and 40 female) aged 65 to 84 years (mean age – 72.2±4.7 years) who underwent elective cardiac surgery. Perioperative factors were analyzed. The primary endpoint of the study was a 30-day mortality rate.Results.The total 30-day mortality rate was 13.4 % (17 patients). Perioperative predictors of 30-day mortality rate were the calculated values of the CAF scale (p=0.006), the surgery volume (p=0.044), the use of extracorporeal blood circulation (p=0.048).Conclusion.The use of qualitative assessment of biological age allows to more accurate predict the mortality in cardiac elderly patients.

Published: March 2019

Theobjectivewas to evaluate the effectiveness of endobronchial photodynamic therapy (PDT) for preventing a non-small cell lung cancer (NSCLC) relapse after R1 resection with positive bronchial resection margins.Material and methods.This study included 17 patients. The planned morphological diagnostics revealed the presence of tumor cell complexes at the bronchial resection margins in 5 (29 %) patients (cancer in situ – 2, invasive cancer – 3), in peribronchial tissues – in 5 (29 %) patients, in lymphatic vessels at the resection margins – in 7 (41 %) patients.Results.All patients underwent one session of endobronchial PDT as an adjuvant treatment. No complications of PDT were noted. The five-year observation revealed a relapse at the bronchial stump area in 1 patient only (6 %). 16 (94 %) patients lived for 1 year, 12 (71 %) patients – for 5 years. Long-term results were significantly worse in patients with tumor complexes in lymphatic vessels at the bronchial resection margins (5-year survival rate – 29 %, p=0.04), with pN2 (0 %, p=0.01), lung adenocarcinoma (20 %, p=0.03).Conclusion.The use of endobronchial PDT as an adjuvant treatment for patients with NSCLC after R1 resection with positive bronchial resection margins is simple, safe and characterized by good immediate and long-term results.

Economic effectiveness of urban railway infrastructure investments in the light of globalization and regional development. Study on example of Pomeranian Metropolitan Railway construction
Authors: Miecznikowski Stanisław , Radzikowski Tomasz 
Published: March 2019

The myth of a borderless world pillars of open markets – the USA and the UK – are wobbling, and China is positioning itself as globalization staunchest defender. But is a mass retreat from globalization really the right approach for companies in these uncertain times? Or short of packing up and returning home, should they focus on localization – that is producing or even innovating where they sell-as the strategy of choice? Recall that as recently as a decade ago, business leaders and politicians believed that the world and that global companies, unconstrained by countries borders, would soon dominate the world economy. Today’s turmoil calls for a more subtle reworking of multinationals’ strategies organizational structures, and approaches to societal engagement. Poland has already been a beneficent of EU funds. Actually Polish internal indebtedness is increasing and Poland will not be able to use EU funds in the future.

The authors would like to present the Polish issue of planning investments financed by EU funds, e.g. the project of the Pomeranian Metropolitan Railway. Construction of this railroad is the first successful project in Poland to build a new railroad since the transformation of the state system in 1989. The project was financed by the European Regional Development Fund. The decision to build the line and award the grant was made on the basis of a feasibility study. A key element of this document was the CBA analysis, which was carried out on the basis of the Blue Book for railway transport.

A narrow look at the economic aspects and the earlier underestimated costs of the investment caused that the investment is unfinished. The question should be asked is whether use of another method of economic analysis would help to complete this investment without the need for over a dozen years of staging investment expenditures? Difficulties with the economic efficiency account are similar to the barriers to the development of globalization.

Authors: García Judit , Peñafiel Heredia Daniel , Rodríguez Remberto 
Published: March 2019

Las aguas residuales de las lavadoras-lubricadoras de autos contienen grandes cantidades de hidrocarburos que son descargados en el alcantarillado público sin pasar por un tratamiento adecuado, incumpliendo la normativa. En este trabajo se evaluó el proceso de biorremediación de hidrocarburos totales en las aguas residuales de Puyango, para esto se aplicó un cultivo mixto de microorganismos degradadores de hidrocarburos y derivados, mediante la técnica de bioaumentación (aplicación directa de microorganismos). Para ello se realizó una caracterización de las aguas residuales, además se determinó el contenido de hidrocarburos totales del petróleo (TPH, por su sigla en inglés) y el caudal, durante siete días. Se aplicó un tratamiento consistente en una mezcla de bacterias: Acinetobacter sp., Pseudomonas sp. y Mycobacterium sp en forma sólida (tableta de 80 g) con una concentración mínima de 4 x 108 UFC/ml soluble en agua, utilizando dos tabletas durante 30 días. Se determinó la concentración del TPH semanalmente, graficando la variación temporal y cuantificando el % de remoción. Los resultados indican que la técnica de bioaumentación fue efectiva (p=0.003) en la remoción del TPH obteniéndose porcentajes por encima del 86%. El tiempo de mayor remoción del TPH se obtuvo en la tercera semana de tratamiento con 92 %. Además, se obtuvo remociones de DQO-40 %, Aceites y grasas -50 %, Tensoactivos -43 % cumpliendo así la normativa vigente de descarga al alcantarillado público para el TPH.

Published: March 2019

La investigación tuvo como objetivo principal determinar las deficiencias de la situación actual de la cadena de valor del cacao peruano, y plantear propuestas de mejora integrales en la misma, a través de los factores competitivos en cuestión. Para ello se utilizaron como herramientas: el análisis de la cadena de valor y el análisis del diamante competitivo de Porter. El análisis de la cadena de valor, permitió una “fotografía” completa de quienes han participado, de qué manera, con qué intereses, sus interrelaciones, visualizando las necesidades y potencialidades de los diferentes actores para el mejoramiento individual y en conjunto. En el análisis del diamante competitivo de Porter se interrelacionaron los componentes del sector del cacao. Las mejoras en la cadena de valor fueron: el resultado de la vinculación de la estrategia, la estructura y la rivalidad entre las compañías del sector, la condición de los factores, las condiciones de la demanda, y los sectores conexos y de apoyo o clúster, que son actividades ligadas entre las empresas que participan en un sector del cacao; todas fundamentales para alcanzar la ventaja competitiva; que van a reducir la brecha de los diferentes eslabones convertidos en factores competitivos, para dar lugar al desarrollo de capacidades y generar oferta exportable de cacao en diferentes nichos de mercado, que a la fecha está alrededor de 100 000 toneladas aproximadamente. Las operaciones de producción agrícola, pos cosecha y transformación requieren mejoras sustanciales para evitar costos de no calidad y la baja retribución del valor del cacao hacia el agricultor. De los problemas encontrados se derivan un conjunto de lineamientos estratégicos en el corto, mediano y largo plazo, proyectando para el futuro una cadena competitiva, como el posicionamiento por “diferenciación”, direccionada a producir cacao fino o de aroma, cacao orgánico e innovación en productos con cacao peruano.

Technology and equipment for processing of secondary hydrocarbons
Authors: Zhuravski G. I. 
Published: March 2019

The concept of “steam thermolysis”, specifically, the use of overheated water steam as an effective coolant and inert medium to reduce the formation of environmentally hazardous compounds in the process of thermochemical decomposition of organic waste and to have the possibility of obtaining valuable end products that can be certified as fuels, fuel additives, raw materials and components for certain products, is grounded. Based on the study of decomposition of organic waste in a superheated water steam environment, a thermochemical technology for processing of hydrocarbon-containing raw materials has been developed.To implement the technology of processing hydrocarbon-containing raw materials, it is necessary to heat the raw material up to the specified temperature, maintain the raw material at this temperature for the time required for complete removal of hydrocarbons and water, to cool and condense the steam-gas products, and to cool the solid products. All these processes (heating, holding at a given temperature, cooling, condensation) are associated with the supply of energy (heating and soaking) and energy removal (condensation and cooling of products). On the basis of the law of conservation of energy, the heat transfer equation is formulated and its solution is computed, which makes it possible to calculate the necessary time for the complete course of the thermal decomposition of hydrocarbons.The new technology is instrumentally designed as a line for processing of oil-containing waste, installed on the territory of the company Industrial-transport corporation LLC (Angarsk, Russia). With the help of this equipment, it was proved experimentally under experimental industrial conditions, that as a result of steam thermolysis of oil sludges, the formation of a gasoline fraction occurs, the content of kerosene and diesel fractions increases, and the content of the black oil fraction decreases significantly.

Introduction: Language learning is probably as ancient as human kind. Man has been communicating in one form or the other since the time he evolved. Such means of communication has undergone a process of evolutionary changes to stabilize as language and provide an identity to its user.
With language becoming the principal source of interaction, the man in his curiosity and wisdom, began to analyse it to facilitate teaching/learning of the same easily. The present article is a conclave of such attempts (researches) and takes into account a historical perspective. While doing so an attempt has been made to discuss topics such as Second Language Acquisition (SLA), Continuing Professional Development (CPD) and Information Communication Technology (ICT).
