Exilio y migración de retorno. Una reflexión comparativa para el caso colombiano
Authors: Cruz Buitrago Jorge Armando
Published: November 2018

This paper aims at exploring return migration’s phenomenon of Colombian exiles from a comparative lecture of what happened in the Southern Cone of Latin America during the military dictatorships. In this respect, a dialogue is established between different literary stories of exiles from the Southern Cone that show the existential complexity of the return process and, in some cases, the impossibility of returning. This dialogue will provide elements of analysis that will allow the understanding of exile as a rupture and return migration as a possibility that opens up in the post-conflict.

Published: November 2018

The aim of this research was to study the effect of graphite addition in the process of synthesis of tribological materials based on tin sulphides. The tin sulphides powders were synthesized from selected precursors by pyrometallurgical method in rotary tilting tube furnace. The thermodynamic parameters of the synthesis were determined using HSC Chemistry software modelling package. In addition, the synthesis process was also characterized by the thermal analysis method: simultaneous differential scanning calorimetry and thermogravimetry (DCS-TGA). The characterization of the synthesized tin sulphides powders included analysis of chemical composition by optical emission spectroscopy, phase composition identification by X-ray diffraction (XRD) and examination of morphology, as well as elemental composition by scanning electron microscopy (SEM) with energy-dispersive spectroscopy (EDS). The hexagonal SnS2 and orthorhombic Sn2S3 phases were formed after the thermal treatment of starting powders in nitrogen atmosphere. The obtained results indicate the positive effects of the graphite addition which enables the synthesis of tin sulphide powders with appropriate content of sulphide phases with minimal loss of sulphur.

The aim of this study was to compare endothelial permeability, which is considered a hallmark of coronary artery disease, between patients with different HbA1c levels using an albumin-binding magnetic resonance (MR) probe. This cross-sectional study included 26 patients with clinical indication for X-ray angiography who were classified into three groups according to HbA1c level (<5.7% [<39 mmol/mol], 5.7–6.4% [39–47 mmol/mol], and ≥6.5% [48 mmol/mol]). Subjects underwent gadofosveset-enhanced coronary magnetic resonance and X-ray angiography including optical coherence within 24 h. Contrast-to-noise ratios (CNRs) were assessed to measure the probe uptake in the coronary wall by coronary segment, excluding those with culprit lesions in X-ray angiography. In the group of patients with HbA1c levels between 5.7 and 6.4%, 0.30 increased normalized CNR values were measured, compared with patients with HbA1c levels <5.7% (0.30 [95% CI 0.04, 0.57]). In patients with HbA1c levels ≥6.5%, we found 0.57 higher normalized CNR values compared with patients with normal HbA1c levels (0.57 [95% CI 0.28, 0.85]) and 0.26 higher CNR values for patients with HbA1c level ≥6.5% compared with patients with HbA1c levels between 5.7 and 6.4% (0.26 [95% CI −0.04, 0.57]). Additionally, late atherosclerotic lesions were more common in patients with high HbA1c levels (HbA1c ≥6.5%, n = 14 [74%]; HbA1c 5.7–6.4%, n = 6 [60%]; and HbA1c <5.7%, n = 10 [53%]). In conclusion, coronary MRI in combination with an albumin-binding MR probe suggests that both patients with intermediate and patients with high HbA1c levels are associated with a higher extent of endothelial damage of the coronary arteries compared with patients with HbA1c levels <5.7%.

To identify genetic variants associated with diabetic retinopathy (DR), we performed a large multiethnic genome-wide association study. Discovery included eight European cohorts (n = 3,246) and seven African American cohorts (n = 2,611). We meta-analyzed across cohorts using inverse-variance weighting, with and without liability threshold modeling of glycemic control and duration of diabetes. Variants with a P value <1 × 10−5 were investigated in replication cohorts that included 18,545 European, 16,453 Asian, and 2,710 Hispanic subjects. After correction for multiple testing, the C allele of rs142293996 in an intron of nuclear VCP-like (NVL) was associated with DR in European discovery cohorts (P = 2.1 × 10−9), but did not reach genome-wide significance after meta-analysis with replication cohorts. We applied the Disease Association Protein-Protein Link Evaluator (DAPPLE) to our discovery results to test for evidence of risk being spread across underlying molecular pathways. One protein–protein interaction network built from genes in regions associated with proliferative DR was found to have significant connectivity (P = 0.0009) and corroborated with gene set enrichment analyses. These findings suggest that genetic variation in NVL, as well as variation within a protein–protein interaction network that includes genes implicated in inflammation, may influence risk for DR.

Published: November 2018

OBJECTIVE

Novel biomarkers are needed to better predict coronary artery calcification (CAC), a marker of subclinical atherosclerosis, and diabetic kidney disease (DKD) in type 1 diabetes. We evaluated the associations between serum uromodulin (SUMOD [a biomarker associated with anti-inflammatory and renal protective properties]), CAC progression, and DKD development over 12 years.

RESEARCH DESIGN AND METHODS

Participants (n = 527, 53% females) in the Coronary Artery Calcification in Type 1 Diabetes (CACTI) study were examined during 2002–2004, at a mean age of 39.6 ± 9.0 years and a median duration of diabetes of 24.8 years. Urine albumin-to-creatinine ratio (ACR) and estimated glomerular filtration rate (eGFR) determined by the CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) creatinine equation were measured at baseline and after a mean follow-up period of 12.1 ± 1.5 years. Elevated albumin excretion was defined as ACR ≥30 mg/g, rapid GFR decline (>3 mL/min/1.73 m2/year), and impaired GFR as eGFR <60 mL/min/1.73 m2. SUMOD was measured on stored baseline plasma samples (Meso Scale Discovery). CAC was measured using electron beam computed tomography. CAC progression was defined as a change in the square root–transformed CAC volume of ≥2.5.

RESULTS

Higher baseline SUMOD level conferred lower odds of CAC progression (odds ratio 0.68; 95% CI 0.48–0.97), incident elevated albumin excretion (0.37; 0.16–0.86), rapid GFR decline (0.56; 0.35–0.91), and impaired GFR (0.44; 0.24–0.83) per 1 SD increase in SUMOD (68.44 ng/mL) after adjustment for baseline age, sex, systolic blood pressure, LDL cholesterol, and albuminuria/GFR. The addition of SUMOD to models with traditional risk factors also significantly improved the prediction performance for CAC progression and incident DKD.

CONCLUSIONS

Higher baseline SUMOD level predicted lower odds of both CAC progression and incident DKD over 12 years in adults with type 1 diabetes.

Barriers to Sentinel Events Reporting in Tertiary Hospital at Dammam, Saudi Arabia
Authors: Ali Rania
Published: November 2018

The objective of this study was to find out the barriers of sentinel events reporting at tertiary hospital and then formulate recommendations to ameliorate based the findings of this study. The study was carried out in 2015 and conducted as two parts; the first part is a retrospective data, review of Occurrence Variance Reports forms according to the reporter. The second part was through self-administered questionnaires, which was randomly distributed to the hospital staff. A total of 120 completed questionnaires out of 135 were received.  In this study, we found that the commonest reasons that prevent the hospital staff from reporting the sentinel events are poor communication of policy and procedure of sentinel events reporting, lack of motivation among the staff to report sentinel events in 28 % and 26 % respectively. Staff fear of punitive actions from the hospital administration was rated as the first and second priority reason in preventing employee reporting sentinel events in about half of the cases. No feedback from reporting sentinel events was the reason for underreporting in about one fifth. Sentinel events definition was not clear and sentinel cases reporting form was not available in 14 % and 15 % respectively. This study highlights the common factors that may contribute to under-reporting of sentinel events in tertiary hospital. The findings may be useful in formulating beneficial strategies to improve reporting which will have great value on quality of care and patient safety.

Published: November 2018

The aim of this study is a description of counselor characters obtained from the values of Sanghyang Siksakandang Karesian (SSK) manuscript. Qualitative approach was used in which the data, analysis, and interpretation conformed to the principles of hermeneutics. As a method, hermeneutics was employed to interpret the text meaning within the SSK. The research procedure comprised: 1) selection of texts source, 2) dialogic process involving negotiation and re-negotiation of texts interpretation until the full understanding of the texts was gained, and 3) concept writing. The results suggest that in the SSK, there are three focal aspects supporting the counselor’s personal quality; that are: 1) religious, submissive and obidient to The Most Supernatural Power of God (Batara Seda Niskala); 2) being wastu siwong, a human being having good attitudes, excel at science, and knowledgable about the value of life; and 3) comprehensive about pangimbuh ning twah, the complementary thing toward the success of life in society. These three aspects in this study form a Rampes counselor.

Authors: Parhizgar Sara Sadat , Sibouyeh S.
Published: November 2018

In this paper silver nanoparticles (NPs) which are synthesized by a simple plasma arc discharge method, that is a kind of electrochemical methods, are examined. The method is very simple and silver NPs are obtained very fast by means of two polished silver plates and electrochemical cell. The effects of changing some terms of the experiment including using Hydrogen peroxide (H2O2), temperature and the medium of experiment on oxygen percent and crystalline structure of silver NPs have been studied by transmission electron microscopy, UV-visible spectrophotometery, and X-ray diffraction. Water medium gets larger nanoparticles with less oxygen content compare to air medium. The size of synthesized nanoparticles become smaller and they also become more spherical by using H2O2 in air medium. In water medium, the size and concentration of the silver crystallite increase by temperature growth and adding H2O2  respectively.
ENERGY-MOMENTUM LOCALIZATION PROBLEM IN HIGHER DIMENSIONAL KASNER TYPE UNIVERSE MODEL
Authors: AYGÜN Sezgin
Published: November 2018

Considering Landau-Lifshitz (LL), Papapetrou (PP), Bergmann-Thomson (BT), Møller (ML), Einstein (EI) and Tolman (TL) energy and momentum prescriptions in general relativity theory (GR) and the tetrad theory of gravity (TG), we get total energy and momentum distributions based on  dimensional Kasner type universe model. Using different energy and momentum prescriptions, we obtain zero energy and momentum distributions in different gravitation theories. Also, we calculate two and three dimensional Kasner type universe solutions in GR and TG. Our solutions consist with each other. The obtained results are agree with previous studies of Kıy and Aygün for higher dimensional Bianchi type I universe, Do ru et al. for 5-D Bianchi type I universe, Banerjee, Xulu, Aydo du and Saltı, Radinschi, Lau and Vargas for 4-D Bianchi type I universe, Taşer et al. for 5-D Kasner universe, Havare and Saltı, Saltı for 4-D Kasner solutions, Tryon, Cooperstock, Rosen and Johri et al. for 4-D FRW universe in GR and TG.  All these studies, the authors have obtained the energy-momentum distribution is zero in GR and TG. However we could say that GR and TG are equivalent and these definitions are working properly for higher dimensional Kasner type universe in GR and TG.
Mehar method for finding exact fuzzy optimal solution of fully fuzzy linear programming problems
Authors: Gupta Gourav
Published: November 2018

There are several methods in the literature to find the fuzzy optimal solution of fully fuzzy linear programming (FFLP) problems. However, in all these methods, it is assumed that the product of two trapezoidal (triangular) fuzzy numbers will also be a trapezoidal (triangular) fuzzy number. Fan et al. (“Generalized fuzzy linear programming for decision making under uncertainty: Feasibility of fuzzy solutions and solving approach”, Information Sciences, Vol. 241, pp. 12–27, 2013) proposed a method for finding the fuzzy optimal solution of FFLP problems without considering this assumption. In this paper, it is shown that the method proposed by Fan et al. (2013) suffer from errors and to overcome these errors, a new method (named as Mehar method) is proposed for solving FFLP problems by modifying the method proposed by Fan et al. (2013) . To illustrate the proposed method, some numerical problems are solved.
An Asymptotic Preserving Scheme for Kinetic Models for Chemotaxis Phenomena
Authors: Bellouquid Abdelghani , Tagoudjeu Jacques
Published: November 2018

In this paper, we propose a numerical approach to solve a kinetic model of chemotaxis phenomena. This scheme is shown to be uniformly stable with respect to the small parameter, consistent with the uid-di usion limit (Keller-Segel model). Our approach is based on the micro-macro decomposition which leads to an equivalent formulation of the kinetic model that couples a kinetic equation with macroscopic ones. This method is validated by various test cases and compared to other standard methods.
The Political Replacement Effect in a Kinetic Model of Social Dynamics with Phase Transition
Authors: Dolfin M.
Published: November 2018

The political replacement effect is an interesting socio-political hypothesis introduced by Acemoglu and Robinson and statistically tested. It may determine, under some conditions, the phenomenon of innovation blocking, possibly leading to economic backwardness in a society. In a previous paper, we have introduced a kinetic model with stochastic evolutive game-type interactions, analyzing the relationship between the level of political competition in a society and the degree of economic liberalization. In the present paper we model we model the possibility of having a sort of phase transition occurring in the system when the phenomenon of blocking of the introduction of technological innovation, intended in a broad sense, appears. Crossing a critical point, the rules of interactions change by means of slightly different transition probabilities nevertheless determining very significant differences in the resulting long-term solutions.
On an optimal control strategy in a kinetic social dynamics model
Authors: Knopoff Damián A. , Torres Germán A.
Published: November 2018

Kinetic models have so far been used to model wealth distribution in a society. In particular, within the framework of the kinetic theory for active particles, some important models have been developed and proposed. They involve nonlinear interactions among individuals that are modeled according to game theoretical tools by introducing parameters governing the temporal dynamics of the system. In this present paper we propose an approach based on optimal control tools that aims to optimize this evolving dynamics from a social point of view. Namely, we look for time dependent control variables concerning the distribution of wealth that can be managed, for instance, by the government, in order to obtain a given social profile.

Published: November 2018

The general family of Galerkin variational integrators are analyzed and a complete classification of such methods is proposed. This classification is based upon the type of basis function chosen to approximate the trajectories of material points and the numerical quadrature formula used in time. This approach leads to the definition of arbitrarily high order method in time. The proposed methodology is applied to the simulation of brownout phenomena occurring in helicopter take-off and landing.

Authors: Walczak Renata , Kálmán Anikó
Published: November 2018

This article presents a qualitative study of lifelong learning (LLL) requirements of university employees from the Warsaw University of Technology (WUT) and the Budapest University of Technology and Economics (BME). The main aim of the study was to gain understanding of young people expectations and attitudes towards LLL. Aims of the study included: identification of employees’ requirements in terms of LLL; identification of education activities and employee perception of university activities. Data for the study were gathered in individual interviews. The same, standardized openended questions were used in both institutions to allow comparison of the results. Interview questions concerned the willingness of participation in LLL, education forms, areas of education and perception of the university. The participants of the interviews were 24 young people from the WUT and BME. Research shows that there are no significant differences between Polish and Hungarian representatives who are eager to learn and have many interests and positive features; however, they have high requirements and expectations. This research will allow to prepare informative and effective LLL universities’ strategies.

The intensive expansion of the industry has been aligned with widely implemented policies of personal development and leadership, aimed to grow and prepare internal human resources for more challenging roles in newly established projects and teams. The paper presents the results of empirical research examining the perception of those schemes and policies, from the perspective of workers employed in the polish offshore service delivery centers.
Storms in Europe (1994–2005) – Their Relationship with Continentality of Climate
Authors: Grabowska Katarzyna
Published: November 2018

The objective of the paper is to determine the influence of continentality of Europe’s climate, increasing to the east, on the number of days with thunderstorms during the years 1994–2005 in ten chosen European cities.

In Europe, days with thunderstorms come from cities located in zones from the west to the east, beginning from Dublin, through London, Paris, Munich, Prague, Minsk, Kiev, Kharkov and up to Moscow. The well matched stations show the gradually increasing continentality of Europe’s climate.

From an analysis of the number of days with thunderstorms, the Gorczyński continentality index and the long-term mean annual amplitude of air temperature it may be concluded that, in as much as the values of the amplitude and index increase with distance from the ocean, it is not always so with the number of days with thunderstorms. Despite greater climate continentality, Minsk, Kiev and Moscow have much fewer storm days than Warsaw or Prague.
The Vistula River as One of Poland’s Symbols and Its Perception by High School Students from Vistula Towns
Authors: Angiel Joanna
Published: November 2018

This paper presents the perception of the Vistula river, the most important of Poland’s rivers, by high-school students from selected Vistula towns and cities. The study of the perception of this river, conducted in 2006-2007, concerned, among other things, the symbolism of the Vistula, its role in nature and landscape of Poland, as well as the course of the river flowing through Poland. It was ascertained that most students perceive the Vistula as a symbol of Poland or the longest river in Poland, but they do not notice, for instance, its ecological role, although they are aware of its role in the landscape of Poland. The results of the study determine the direction and the topics of the geographic education concerning the Vistula river in Polish schools.

Authors: Żmudzka Elwira
Published: November 2018

The purpose of the report is to determine trends in thermal conditions in the Polish part of the Tatra Mountains. The results of studies were compared with the results of analogous analyses, carried out for the area of lowland Poland. The study makes use of the data from the weather stations in Zakopane and on Kasprowy Wierch Mt. from the years 1951-2006, mainly from 1966-2006. The thermal conditions in lowland Poland was determined on the basis of the area-averaged time series (45 stations). Various thermal characteristics were considered. The increase of the rate of upward trend in temperature at the turn of the 21st century, as well as the change of the seasonal distribution of the warming in comparison with the preceding long-term periods, have been documented. Symptoms of increase of the thermal continentality have also been observed.

Published: November 2018

During the last century about 100 indices were developed to assess influences of the atmosphere on human being. However, most of them have not close relationships with physiological reactions in man. In 1999 International Society of Biometeorology established special study group do develop new Universal Thermal Climate Index (UTCI). Since 2005 these efforts have been reinforced by the COST Action 730 (Cooperation in Science and Technical Development). In February 2009 the Action was terminated and UTCI was developed.

The new UTCI index represents air temperature of the reference condition with the same physiological response as the actual condition. The index base on Fiala model that is one of the most advanced multi-node thermophysiological models and include the capability to predict both whole body thermal effects (hypothermia and hyperthermia; heat and cold discomfort), and local effects (facial, hands and feet cooling and frostbite). The model consists of two interacting systems: the controlling active system; and the controlled passive system. The assessment scale of UTCI bases on the intensity of objective physiological reactions to environmental heat stress in wide range of weather and climates. The index can be applicable in various research, for example in weather forecasts, bioclimatological assessments, bioclimatic mapping in all scales (from micro to macro), urban design, engineering of outdoor spaces, consultancy for where to live, outdoor recreation and climatotherapy, epidemiology and climate impact research.

The paper presents thermophysiological principles of UTCI as well as some examples of its application to assess bioclimatic differentiation of Europe.

Heterogeneidad y dependencia sintética. Más sobre Kant y el (anti)conceptualismo
Authors: Lazos Efraín
Published: November 2018

Este ensayo discute los vínculos entre dos tesis provenientes de la Doctrina trascendental de los elementos, en la Crítica de la razon pura, de Immanuel Kant. La primera es que las intuiciones y los conceptos son representaciones de naturaleza distinta, y se conoce como la tesis de la heterogeneidad. La segunda, llamada tesis de la dependencia sintética, es que las intuiciones dependen de la actividad sintética del entendimiento. La propuesta principal del ensayo es que ambas tesis solo son conciliables si se abandona el conceptualismo, posición sostenida, entre otros, por Pedro Stepanenko (2016), y según la cual las intuiciones solo tienen contenido representacional si están subordinadas al entendimiento.
La apropiación de la phrónesis (El debate entre Gadamer y Tugendhat)
Authors: Velázquez José Luis
Published: November 2018

La elección del concepto de phrónesis tiene para Gadamer un doble objetivo: unir la hermenéutica y la ética de Aristóteles, y presentar el problema de la aplicación del conocimiento moral como el modelo de problema hermenéutico. Teniendo en cuenta las aportaciones críticas de E. Tugendhat, aquí se analizan algunas dificultades en el planteamiento de Gadamer derivadas de la imposibilidad de la phrónesis para aplicar correctamente el conocimiento moral y para justificar lo que es moralmente válido.

Authors: González Diego Luis , Camargo Manuel , Sanchez Julián
Published: November 2018

Se estudian las propiedades dinámicas de un modelo de suspensión coloidal bidimensional cuyas partículas son depositadas lentamente sobre un sustratounidimensional bajo la acción de un campo externo. Una vez que las partículas son depositadas en el sustrato pueden difundirse lateralmente sobre este último. Usando un modelo analítico basado en las ecuaciones de Langevin y de Fokker-Plank se estudia la dinámica de una partícula en la suspensión y sobre el sustrato. En particular, se calculanla tasa de deposición promedio sobre el sustrato, F, así como también la constante de difusión de las partículas sobre el sustrato, D. Los resultados del modelo analítico propuesto presentan un buen acuerdo con los encontrados usando simulaciones numéricasbasadas en dinámica molecular. Este modelo sencillo permite explorar la posibilidad de usar coloides para la formación de estructuras mediante la técnica de crecimiento epitaxial, la cual es relevante en distintos campos de aplicación.

Los geles poliméricos tienen un rango amplio de aplicaciones biomédicas incluyendo su uso para el crecimiento de tejidos, la liberación controlada de fármacos, la inmovilización de enzimas, entre muchas otras. Debido a la capacidad que tienen los geles para almacenar agua en su interior y  a  la  conducción  iónica  que  se  puede  generar  a  través  de  grupos  funcionales  ionizables,  estos materiales pueden llegar a tener aplicaciones en el diagnostico clínico y la electroterapia. En la presente investigación se prepararon geles conductores a base de quitosano, el cual es un polímero biodegradable  y  biocompatible,  usando  glutaraldehído  como  agente  entrecruzante.  Los  geles  de quitosano  se  caracterizaron  por  espectroscopia  infrarroja  con  transformada  de  Fourier  (FTIR)  y se  determinaron  además  sus  valores  de  viscosidad  (μ),  conductividad  eléctrica  (κ)  y  pH.  Estas propiedades variaron conforme se modificó el grado de entrecruzamiento. Una de las muestras con valores comparables con los geles de formulación comercial presentó una viscosidad absoluta de 365x10 3  cP, una conductividad iónica de 0.2140 Sm -1  y un pH de 3.5, valores prometedores para su aplicación en geles comerciales con aplicaciones biomédicas.

Authors: Martínez Eliana , Torres Celina , Díaz Jaime Ernesto
Published: November 2018

The main pathogens that affect the foliage and floral bracts of Heliconia cultivars in Las Heliconias National Park (Caicedonia, Colombia) were identified. Random samples were taken of foliage and floral bracts presenting symptoms of damage caused by phytopathogenic fungi. The degree of damage was described qualitatively and was correlated with the phytosanitary state of the crop. Reports of the evaluated plants indicated that 75% of the pathogens resided in the foliage and 25% resided in the floral bracts. The statistical analysis determined that the microorganisms Aspergillus sp., Fusarium sp., and Nigrospora sp. appeared equally in the two evaluated organs. The fungal genera found associated with plant sickness symptoms were considered to be phytopathogens. The degree of infection and development of disease varied from moderate lesions to severe infection. Reproductive fungi were present in the different plant organs studied and in organic matter residue in the soil.

“Colouredness”, Female Sexuality and Respectability in Irene Sabatini’s The Boy Next Door
Authors: Mtenje Asante Lucy
Published: November 2018

This article examines how race consciousness mediates the performance and experience of femininity, female respectability, and sexual desires in Irene Sabatini’s debut novel, The Boy Next Door. It explores how assumptions of racialised female bodyhood, femininity, and sexuality are constructed and transmitted within an intergenerational framework of the mother-daughter relationship between Lindiwe Bishop and her mother, Mrs Bishop. I argue that in the novel the notion of respectable womanhood is mediated through the desires, the sexual behaviour and the proper conduct of the female sexualised and racialised body. Reading the novel from a theoretical perspective of “hegemonic” and “subordinated” femininities, which takes into account how “other axes of domination such as race, class, sexuality, and age mold a hegemonic femininity, I analyse how the ideology of whiteness mediates discursive performances of femininity, which place certain kinds of femaleness associated with whiteness as superior to others—and how this consciousness also influences ideas about respectability in relation to sexuality.
Production analysis for fractured vertical well in rectangular coal reservoirs
Authors: Li Chen , Dong Zhenzhen , Li Xiang
Published: November 2018

As one kind of unconventional natural gas, coalbed methane is an important energy resource that is subject to active research. Gas exists in coalbed methane reservoirs in two forms: free gas and adsorbed gas. In the course of coalbed methane production, the reservoir experiences pressure decrease, desorption, diffusion, and seepage. Previous models of coalbed methane production were mainly concerned with circular boundaries. However, field tests revealed that some fractured wells possess the characteristics of rectangular boundaries. For fractured rectangular coalbed methane reservoirs, it is necessary to deal with the four boundaries with mirror image theory, which complicates calculations. In addition, the desorption and adsorption process of coalbed methane exerts a strong effect on the seepage process. Furthermore, the complexity of the rectangular coal seam embedded with the finite-conductivity fracture results in a significant computational challenge. For the first time, this paper presented a fast analytical solution for a finite-conductivity fractured vertical well model with either rectangular closed or constant-pressure boundaries in the coal seam. On the basis of the Fick diffusion law and the Darcy seepage law, a mathematical model that considers diffusion in matrix and seepage within natural fractures was established. Then, we integrated the fracture conductivity function method with the hydraulic fracture model to greatly increase computational efficiency. The analytical solutions were validated against a numerical simulation. Parameter sensitivity analysis reveals that interporosity coefficient and storage coefficient, respectively, affect the appearance time and degree of desorption and diffusion. Desorption coefficient mainly describes the capacity of desorption and diffusion. Well storage coefficient, conductivity factor, and skin factor mainly affect the early stage of production. Finally, the proposed solutions were applied to field history match. The model developed is applicable to production analysis and well testing for coalbed methane reservoirs. The new proposed model extended flow mechanism of coalbed methane, and provided a better production and pressure forecast for coalbed methane reservoirs. In addition, the analytical solutions can be used to generate type curves for fractured vertical wells with finite conductivity and in the rectangular boundary, and provide a sound theoretical basis for well tests in the coal seam. The model is also applicable to other types of unconventional gas reservoirs, such as gas shales, in which the same processes are present.

Published: November 2018

Telah dilakukan simulasi distribusi gas polutan cerobong pembuangan pembangkit listrik menggunakan Gaussian Plume Model (GPM) dan Cellular Automata (CA). GPM adalah sebuah metode analitik untuk mempelajari pola sebaran polutan gas di udara akibat proses adveksi dan difusi yang disebabkan oleh angin. Sementara CA merupakan model sederhana yang berbasiskan sel diskrit dalam suatu kisi dengan seperangkat aturan interaksi antar sel tetangga. Sehingga, CA dapat digunakan untuk mensimulasikan dinamika spasial yang disebabkan oleh proses adveksi dan difusi. Polutan yang dipilih sebagai data input adalah Sulfur Dioksida (SO2). Simulasi sebaran polutan di udara dilakukan dengan menerapkan model difusi dan adveksi gas berdasarkan metode CA dan GPM. Simulasi dilakukan pada domain berukuran 100  100 meter dengan dua skenario, yakni skenario satu sumber dan skenario dua sumber identik. Hasil simulasi dari kedua model yang digunakan, menghasilkan pola sebaran polutan yang saling bersesuaian. Hal ini ditunjukkan dengan nilai Root Mean Square Error (RMSE) pada skenario 1 sumber sebesar 0,01229 untuk penampang sumbu-x (y = 50) dan 0,004195 untuk penampang sumbu-y  (x = 35). Sedangkan pada skenario 2 sumber, nilai RMSE sebesar 0,02032 untuk penampang sumbu-x (y = 60) dan 0,004814 untuk penampang sumbu-y (x = 50).
