Authors: Babanov S A , Baraeva R A , Budash D S , Baykova A G
Published: May 2018

A complete physical examination of 145 patients with various forms of hand-arm vibration syndrome (HAVS) and 30 patients of control group was performed in order to solve the aims and objectives of the research. The HAVS forms included 1st stage HAVS associated with local vibration, 2nd stage HAVS associated with local vibration, 2nd stage HAVS associated with local vibration comorbid with hypertension, 1st stage HAVS associated with general vibration, 2nd stage HAVS associated with general vibration, 2nd stage HAVS associated with general vibration comorbid with hypertension. It was observed that endothelial dysfunction in HAVS, especially when comorbid with hypertension, is accompanied by immune alterations such as humoral immunity factors and cytokines imbalance and is characterized by pro-inflammatory cytokine levels increase (IL -1β, IL -8, TNF-α) and anti-inflammatory cytokine level decrease (IL-4) from exposure to production vibration regardless of its type especially when comorbid with hypertension. It is proven that in isolated HAVS associated with local or general vibration, especially when comorbid with hypertension, endothelial dysfunction is characterized by increase of endothelin-1 serum level and growth factors such as transforming growth factor β1 (TGF-β1) and vascular endothelial growth factor А (VEGF-A) increase. Increase of endothelin-1 serum level in patients with HAVS is associated with hemostatic alterations such as platelet-derived growth factor ВВ (PDGF-BB), fibronectin, and Willebrand factor increase.

The management of patients with cardiovascular pathology and comorbid obstructive pulmonary diseases seems to be an urgent problem against the background of their widespread prevalence among the adult population. According to the latest recommendations of GOLD 2017, it is not possible to diagnose COPD and to select options for pharmacotherapy without assessing the symptoms. Evaluation of symptoms in patients with cardiorespiratory pathology is a key element in the diagnosis of both respiratory and cardiovascular deseases. It is important to conduct differential diagnosis of both nosologies for reliable evaluation of the results of standardized respiratory questionnaires. Many respiratory questionnaires have been developed now; some of them have been validated and recommended for use in clinical practice in patients with COPD and asthma. However, their sensitivity and specificity are different, these questionnaires can`t be used interchangeably. In some cases, a decrease in the informative value of standardized respiratory questionnaires was revealed in patients with comorbid cardiovascular and obstructive pulmonary diseases. There are extremely few scientific works, that assess the same aspects of this problem. In connection with this, the development of specialized questionnaires for patients with comorbid cardiovascular and obstructive pulmonary pathology is relevant.
Pulmonary hypertension: reasonable selection of specific therapy
Authors: Karoli N A , Sazhnova S I , Rebrov A P
Published: May 2018

Pulmonary hypertension is characterized with persistent increase in pulmonary vascular resistance leading to progressive worsening of right ventricular failure and death. The basis for pulmonary arterial hypertension is structural changes in pulmonary arteries and arterioles caused by endothelial dysfunction. Endothelin-1 is the main pathogenic trigger of pulmonary hypertension and potential target for therapeutic exposure. The efficacy of endothelin receptor antagonists is proved in various preclinical and clinical studies. In patients with pulmonary arterial hypertension, the efficacy of dual and selective endothelin receptor antagonists is comparable despite the varied activity against various receptors. Bosentan is the most widely used pulmonary vasodilator which improves exercise tolerance and decelerates disease progression.

Advances in treatment have led to improved survival of patients with cancer but have also resulted in untoward side effects associated with treatment. Cardiovascular diseases are one of the most frequent of these side effects. Myocardial dysfunction and heart failure, myocardial ischaemia, arrhythmias, arterial hypertension, thromboembolic disease and other cardiovascular complications can interfere with the efficacy of treatment, decrease quality of life, or impact the actual survival of the patient with cancer. This manual discusses concepts for timely diagnosis, intervention, and surveillance of patients treated with cardiotoxic cancer therapies. In this part оf manual we discuss the diagnostic, prevention and treatment aspects of cancer therapy-related thromboembolism and complications of radiotherapy.

Non-storage summer
dry onion crop is among the top 10 agricultural commodities in New Mexico (NM),
USA. In 2000, NM was ranked the second in the nation as the leading state in
growing summer dry onion. According to USDA statistical records, onion
production or sales in NM was valued at $91.4 million. Mesilla Valley is one of
the major onion-producing regions of NM. Due to many years of drought in the
region and the concern for climate change, irrigation managers and decision
makers are interested in quantifying water use or evapotranspiration (ET) and
the number of acreage of onion crop grown in the Valley. This information can
then be used for managing the scarce water resources of the region.  Plant phenology, Landsat-8 satellite data,
and USDA crop data were used to identify onion crops in the Valley (area of
about 47,000 ha) and to determine their consumptive water use or ET using
remote sensing Regional ET Estimation Model (REEM) from 2014 through 2016. Time
series of NDVI clearly identified Fall and Spring-season onion crops in the
Valley. REEM estimated Spring-season onion crop maximum ET of 973 mm in 2015 and
975 mm in 2016 during the growing season. These values compared reasonably well
to ET estimates of 894 and 955 mm for the same periods (i.e. 2015 and 2016)
using FAO-56 crop coefficient based method. 
The methodology presented could be used in other regions to identify
onion crops and their consumptive water use.Key words:Onion, NDVI, Evapotranspiration, Landsat-8,

Crises in a Doctoral Research Project: A Comparative Study
Authors: Katz Reuven
Published: May 2018

Aim/Purpose: To present quantitative results of an investigation that assessed crises reported by doctoral candidates while working toward their degree.

Background: Crises that candidates encounter during their doctoral journey may lead to attrition from the doctoral program. A crisis in a doctoral project has several characteristics that must be understood in order to identify the crisis and, if possible, take corrective actions. Our study investigates various types of potential crises and the way candidates experience them.

Methodology: We conducted a survey among enrolled doctoral candidates at five universities in Israel and three technological universities in Western Europe. We compared the answers of Israeli Social Sciences and Humanities candidates with those of Israeli Science and Engineering candidates; we also compared the answers of Israeli Science and Engineering students with their Western European peers. We applied statistical analysis to identify and compare significant patterns of reported crises among these three groups of candidates. In addition, we tried to find significant relationships between the reported crises and selected parameters that characterize the candidates’ background and learning habits.

Contribution: The research presents quantitative results of typical crises patterns in a comparative study. It shows that while many candidates experience crises, few seek professional assistance.

Findings:Our investigation showed that about 60% of enrolled doctoral candidates reported a crisis. Of the candidates who reported crises, about 70% did not seek professional assistance. Emotional crises were reported by a significantly higher percentage of Social Sciences and Humanities students than of Science and Engineering students. Conversely, expectation crises were reported by a significantly higher percentage of Science and Engineering students than of Social Sciences and Humanities students. Significantly, more Social Sciences and Humanities students reported economic crises than did Science and Engineering students. Students who experienced a crisis reported that it caused delays in the research and affected its quality. As a result of their crisis, over 25% of Science and Engineering students seriously considered terminating their studies.

Recommendations for Practitioners :The results and discussion may be useful as a guide for advisers to better understand the formation of crises among their doctoral students.

Recommendation for Researchers: The quantitative methodology presented in the paper may be applied to investigate additional phenomena in the field of doctoral studies.

Impact on Society : The paper demonstrates that doctoral students are aware of potential crises due to the stressful environment they face. By reducing the number of crises, it may be possible to reduce the current rates of attrition, which have a significant impact on national economy.

Future Research In future work we plan to expand the research to include the US in the comparative study.

Light spectrum optimization for plant growth using biological feedback
Authors: Ahlman Linnéa , Bånkestad Daniel , Wik Torsten
Published: May 2018

The use of light emitting diods (LEDs) as greenhouse illumination is increasingly common. When each LED color is individually dimmable both light spectrum and light intensity can be tuned, which opens up for optimisation of photosynthesis through automatic control of light quality and quantity. However, this requires a non-destructive biological growth signal that can be measured fast, remotely and preferably without interacting with the plants. A potential candidate signal is steady-state chlorophyll a fluorescence gain at 740 nm, defined as dF740/dq, i.e. the difference in fluorescence at 740 nm divided by the difference in incident light quanta caused by a (small) change in intensity of each individual LED color in the lamp (Ahlman et al., 2017). By automatically adjusting the spectrum, to aim for equal fluorescence gains for all LED colors (Wik et al., 2014), the instant photosynthetic rate can be optimised given a preset electric power input to the lamp. When implementing such a controller though, constraints on the spectral distribution are needed to minimise a negative impact on plant morphology.

In this study measurements were conducted (on cucumber and lettuce) under different background light, and at each setting excitation signals were sequentially added by each of six different LED colors (peak wavelength at 400, 420, 450, 530, 630 and 660 nm). The corresponding changes in steady-state fluorescence were measured with a spectrometer and the fluorescence gain (dF740/dq) was calculated for each LED color and at each background light setting. These fluorescence gains were compared in order to evaluate the different LEDs' relative effect on photosynthesis under each of the different background light settings.

Un análisis factorial con dos factores y un diseño de bloques completos aleatorizados fue establecido, lo que permitió analizar la interacción de dos variables principales: pH y [Pb]-incubado. Alfalfa acumula alrededor de 62% de plomo en el suelo a pH = 5,5; 32% más en comparación con las especies de plantas (malezas) que crecen en los suelos experimentales a pH = 5,4. Alfalfa tiene la capacidad gradual de acumulación de plomo a pH = 5.5, principalmente en las hojas en comparación con tallos y raíces. Aunque los suelos experimentales se riegan con aguas del río Bogotá, éstos no pueden ser considerados con niveles excesivos de plomo que ameriten aplicar tecnologías de fito-remediación. A pesar de que se emplean aguas del rio Bogotá para el riego agrícola, no es posible afirmar alguna tendencia creciente de acumulación en los suelos; por lo menos no en los suelos experimentales.

Se considera en la actualidad, que los campos maduros no poseen la energía suficiente para producir por sí solos. Por esta razón, es necesario implementar métodos de recuperación en ellos, para poder así, facilitar la producción.

Luego de llevar a cabo algunos procesos de inyección de agua en el campo de estudio, se busca evaluar la viabilidad de la Inyección de Polímero, como método de recobro mejorado. Así también, se quiere evaluar el impacto de este proceso en la geomecánica de la roca, para luego describir cualitativamente el fenómeno del arenamiento.

El estudio se llevó a cabo por medio de la recopilación de información del Campo, elaborando una descripción del proceso de inyección de polímero y de la geomecánica de las rocas. Acto seguido, se realizó la descripción del modelo conceptual del campo: gracias a ello, se plantean los escenarios de simulación numérica, para observar el incremento de producción del proceso. Luego, se observan los resultados para concluir acerca de la viabilidad del mismo, mediante el software de simulación Eclipse.

Para determinar el mejor escenario, se hicieron los diferentes cambios de propiedades del polímero, y de la iteración de éste con la roca. Luego de obtener los resultados para la producción, una vez implementado el proceso deseado, se evaluó el impacto en la geomecánica de la roca. Para ello se llevó a cabo también la generación del modelo geomecánico del campo.

Luego, tal modelo fue acoplado con la inyección de salmuera, emulando las propiedades del polímero. Se buscó generar las mismas tasas de producción, tanto para petróleo como para agua. Una vez obtenido el ajuste, se procedió a determinar el cambio en los esfuerzos a partir de las simulaciones, y finalmente evaluar cualitativamente el arenamiento en el campo.

En los procesos de perforación offshore, es necesario tener sistemas que garanticen el flujo de información, debido a que las fallas logísticas derivadas de errores en la comunicación pueden aumentar los costos y los tiempos de operación. En este sentido, el objetivo principal de esta investigación es diseñar un sistema de gestión de la información para el apoyo logístico de la perforación offshore, que facilite el abastecimiento de forma óptima y oportuna de los requerimientos de las plataformas ubicadas mar adentro. La construcción del sistema se basó en la identificación de las causas de fallas de comunicación, a través de la revisión de fuentes secundarías, las cuales fueron validadas posteriormente con el uso del método Delphi.

Este artículo presenta un modelo numérico simplificado para visualizar el proceso de desplazamientos en cascada de los átomos de un material. Esto se logra a través de una implementación computacional del potencial de Lennard-Jones y de la solución de las ecuaciones de movimiento mediante el algoritmo de Verlet. Como resultado del código desarrollado, es posible determinar la cantidad de átomos que se desplazan de sus posiciones iniciales.
Equilibrio funcional de las organizaciones basado en el poder
Authors: Martínez Aldana Clemencia
Published: May 2018

El presente documento expone el pensamiento de Henry Mlntzberg y de Thomas Hobbes en relación al tema de poder, como factor esencial para el equilibrio de las organizaciones. De acuerdo con Mintzberg se describen los sistemas los sistemas que intervienen en la coalición interna de las organizaciones. Según las ideas de Hobbes, se fundamenta cómo a partir de la divergencia entre el estado de naturaleza humana y el estado de la sociedad civil, debe existir un poder que obliga a cumplir acuerdos, no por simple voluntades verbales, sino por una ley que compromete.

Authors: Aldana Harold , Gutiérrez Carlos , Ramos Jorge Luis , Jiménez Robinson
Published: May 2018

El Campo Yariguí-Cantagallo fue descubierto a mediados de los años 40’s, y adquirido por ECOPETROL S.Aen el año de 1975. En el mes de Noviembre de 2008, y debido a la disminución de la presión del yacimiento, Ecopetrol decide intervenirlo iniciando la implementación de métodos de recobro secundario. Se realizaría mediante la incorporación de un proceso de inyección de agua, con el fin de mantener la presión del yacimiento y que la producción de hidrocarburos aumente considerablemente. En el año 2010 el Instituto Colombiano del Petróleo de ECOPETROL S.A. inicia una evaluación de la viabilidad del recobro mejorado mediante inyección de químicos en el campo, con el fin de incrementar la producción de petróleo y el factor de recobro. A su vez, disminuir la producción de agua en los pozos productores.Dicha evaluación será hecha mediante el uso de la simulación numérica de yacimientos. Los beneficios del proceso EOR serán analizados a partir de la producción de agua y petróleo, así como de los posibles beneficios económicos que este puede generar.

Authors: Bernal Bustos Claudio Raúl , Morales Granados Miguel Alfonso
Published: May 2018

La solución a un problema no es necesariamente la respuesta favorable, es el soporte, el método de conocimiento con el cual ocurre la respuesta. La presente investigación presente concilia un método de conocimiento que florezca al integrar diversos métodos de conocimientos provenientes de la integración de ciencias diversas alrededor de la solución de un problema común y en la perspectiva de brindar soluciones técnicas y tecnológicas. El modelo pedagógico, que permite comprender el fenómeno educativo que suscita de la integración-articulación de las diversas ciencias y sus métodos de conocimiento, debe reconstruir la enseñanza de las ciencias técnicas a partir de un syllabus superior, y a partir de este, dar forma a la linealidad del syllabus académico.

Se realizó la síntesis de nueve complejos lantánidos de cerio, neodimio y samario con ligandos trans-cinamato (L1), trans-p-clorocinamato (L2) y trans-p-metoxicinamato (L3). La caracterización se realizó mediante espectroscopia FT-IR, análisis térmicos (TGA y DSC) y análisis elemental. Los compuestos obtenidos se utilizaron como catalizadores para la oxidación de canfeno y β-pineno, usando peróxido de hidrógeno (30 %) y ácido peracético (12 %) como agentes oxidantes. En la oxidación de canfeno, el complejo [Nd(L2)3] presentó la conversión más alta (97.99 %) con una selectividad del 84.05 % hacia el ácido 3-canfenilocarboxílico, mientras que en la oxidación de β-pineno, el complejo [Ce(L3)3 . 2H2O] presentó la conversión más alta (82.62 %) con una selectividad hacia la nopinona del 70.52 %.
Nomenclatura de las rocas pelíticas
Authors: Yoris Franklin
Published: May 2018

Este escrito busca unificar la terminología y nomenclatura de las rocas pelíticas en descripciones litoestratigráficas del subsuelo. Está dirigido a los estudiantes de Ingeniería de Petróleo y afines, como material de consulta, y a todos aquellos profesionales y técnicos relacionados con los yacimientos de hidrocarburos que deseen ampliar sus conocimientos sobre el tema. El objetivo no es crear una clasificación taxonómica nueva de nombres de roca o sedimento. Por el contrario, lo que se recomienda es que todos los subtipos composicionales o texturales puedan ser considerados como tradicionalmente se hace, con sistemas de dos, tres o cuatro componentes, es decir, con los triángulos y tetraedros estadísticos tradicionales. Reiteramos: aquí no se busca complicar la discusión terminológica, queda, pues, libre el lector profundizar en esta temática.
