Conclusão: considera-se cada problema como causa ou consequência das dificuldades identificadas. O cuidado humanizado deve provir da desestagnação para enfrentamento da realidade hostil.
Gender matters? How does gender shape risk environment for syringe sharing among people who inject drugsin northern Mexico. Results from a cross-sectional survey
Authors: Ospina-Escobar Angélica , Juárez Fátima
Published: September 2019

Introduction. HIV prevalence among people who inject drugs (PWID) is 5%. Studies have found a HIV prevalence around 10% among women who inject drugs (WWID) and 5% among men. Objective. To describe characteristics of risk environment that play different roles among men and women who inject drugs in Mexico that could be associated with those differentials. Method. In 2012 were interviewed in Hermosillo and Ciudad Juarez in places where population gathered. From them, 824 PWID 74.0% were men and 26.0% were women. Using chi-square test we analyzed associations of gender with demographics characteristics, drug use dynamics, and injecting behaviors. We fitted different generalized linear mixed models with random effects to test the hypothesis that predictors of receptive needle sharing have different effects on men and women. Results. Descriptive analysis showed that women live in conditions of higher vulnerability than men in terms of migration, educational attainment, occupation, and income. Women also reported a higher frequency of drug injection, a higher number of drugs used, and a higher prevalence of sharing needles. Variables significantly associated with the likelihood of sharing needles were: having being injected for someone else at first drug injection (adjusted odds ratio [AOR] = 1.60, 95% confidence interval CI [1.11, 2.25], p < .05); injecting once a day or more (AOR = 1.80, 95% CI [1.17, 2.70], p < .05), using alcohol or drugs at least half of the time at their sexual encounters (AOR = 1.64, 95% CI [1.16, 2.47], p < .05), experience of syringe confiscation by police (AOR = 1.54, 95% CI [1.13, 2.19], p < .05), and perceiving syringe availability as hard or very hard (AOR = 2.29, 95% CI [1.49, 3.32], p < .01). For women the most significant variable associated with syringe sharing was perception of syringe availability (AOR = 3.15, 95% CI [1.25, 7.91], p < .05), while for men was syringe confiscation by police (AOR = 1.74, 95% CI [1.20, 2.50], p < .05). Discussion and conclusion. Results suggests the need to design and implement harm reduction programs that tackle the specific need of WID. Enhancing syringe availability through permanent harm reduction programs, implemented in coordination between public health authorities and community-based organizations, is a basic action to stop HIV spreading among PWID in northern Mexico, along with the decriminalization policies towards these population.

Introduction. Efforts to identify new cases of HIV, HVC and other STIs, through the application of quick tests, focus on people who inject drugs, without taking into account the fact that the use of alcohol and other drugs of abuse inhibits decision making, increasing the transmission of STIs through risky sexual practices. Accordingly, it is necessary to have detection algorithms that consider people who use multiple drugs to improve the identification of new cases and their subsequent linkage with health services. Objective. This paper describes the development process of the OPB-APR model for the detection, counseling and referral of people with HIV and other STIs at addiction treatment centers. Method. The procedure is divided into three phases: 1. A literature review to identify the basic concepts of HIV and other STIs, substance use, risky sexual behaviors, quick tests, and specialized psychological counseling; 2. A feasibility study in which a health professional is trained to implement the OPB-APR model; 3. Drafting of the final version. Results. The final version of the OPB-APR model was obtained, which describes standardized procedures for detection, counseling and referral to health services. Discussion and conclusions. The OPB-APR model aims to strengthen the public health system by increasing the coverage of services for the detection of HIV, HCV and other STIs. The above through the implementation of standardized procedures among specialized and non-specialized health professionals of addiction care centers.
The Position of the European Union in Georgian War
Authors: Skrypnyk Olena
Published: September 2019

In the article explores the reasons for the military conflict in Georgia in August 2008, which arose with the collapse of the Soviet Union and Georgia’s proclamation of independence. As result of the armed conflict between 1992 and 1993, Georgia actually lost control of two regions – Abkhazia and South Ossetia, which de facto were independent under the Russian military support. The position of the European Union regarding this conflict was analyzed, which from the beginning of the Russo-Georgian armed conflict, made significant diplomatic efforts for its speedy settlement. In particular, France has developed six points for a peaceful settlement of the conflict. It was clarified what kind of assistance the EU provided in the termination of Russian-Georgian war. The activity of the EU Monitoring Mission (EUMM) in Georgia has been analyzed, which started its work on October 1, 2008 and is currently in operation. The EUMM is unique among the missions under the overall European Union security and defense policy, she does not provide counseling, does not conduct training or training, she only observing and reporting on the situation in Georgia to allow EU member states to develop a policy towards Georgia. It was concluded that thanks to the creation of the EU Monitoring Mission in Georgia, the EU’s weight in resolving the conflict in Georgia has increased significantly. Despite some technical problems in the initial implementation phase, the Mission is a success for the EU’s Common Security and Defenсe Policy. The Mission continues to make an important contribution to stabilizing the conflict situation in the region, especially after the termination of the OSCE and UN Mission in Georgia. Noted that during the Russo-Georgian War in August 2008, the European Union has developed its own strategy for settling conflicts in the South Caucasus.
An Earthquake Catalog for the Lebanese Region
Authors: Brax Marleine , Albini Paola , Beauval Céline , Jomaa Rachid , Sursock Alexandre
Published: September 2019

The present work aims at establishing an earthquake catalog for seismic hazard assessment in Lebanon. This catalog includes two different parts: historical earthquakes and instrumental earthquakes. The first part of the article describes the work done on the period 31 B.C.E. to the end of the nineteenth century. Numerous studies published in the last 30 yr, devoted to preinstrumental earthquakes in Lebanon, had not been included in any parametric earthquake catalog. A thorough and critical review of these studies was devised to check their respective interpretations of available earthquake records in terms of seismic parameters (date, location, and size) and to select for each earthquake the most reliable interpretation. The second part provides the details on the selection of instrumental solutions for the period 1900–2015 and for magnitudes≥4. From global instrumental earthquake catalogs, we build a unified earthquake catalog for Lebanon and bordering regions. A selection scheme is applied for the choice of the best location and the best magnitude among solutions available. The number of events in the catalog is relatively small, and all earthquakes can be checked one by one. The earthquake catalog is homogenized in moment magnitude. For 89% of the events, an Mw proxy was calculated from the original magnitude, applying conversion equations. The merging of the historical and instrumental periods highlights a specificity of this zone: the instrumental seismicity (1900–2015) corresponds to a relatively quiet period for Lebanon. The historical part, covering 2000 yr, includes similar periods of quiescence, as well as much more active periods with destructive earthquakes.
Complex Triggering Supershear Rupture of the 2018 Mw 7.5 Palu, Indonesia, Earthquake Determined from Teleseismic Source Inversion
Authors: Lee Shiann‐Jong , Wong Tong‐Pong , Lin Tzu‐Chi , Liu Ting‐Yu
Published: September 2019

An Mw 7.5 earthquake struck Palu in the northern coast of Sulawesi island, Indonesia, on 28 September 2018. Its focal mechanism was determined to be a left‐lateral strike‐slip fault, which is generally expected to not produce a tsunami. However, a large tsunami with runup heights of more than 6 m was observed along the coast of Palu city. Here, we show a complex triggering supershear source model as determined by teleseismic waveform inversion. Three asperities with different slip characteristics were found on the 120‐kilometer‐long rupture zone. Significant triggering rupture with a supershear speed was observed south of the epicenter, which was just beneath Palu city. This special rupture process can cause a strong directivity effect that produced anomalously large ground shaking with nonlinear effects in Palu area. The coseismic deformation determined from the inverted source model showed large horizontal displacements. These horizontal movements combined with complex bathymetry and topography could have pushed seawater to generate a tsunami even though the Palu earthquake was a strike‐slip event.
Thrust and Conjugate Strike‐Slip Faults in the 17 June 2018 MJMA 6.1 (Mw 5.5) Osaka, Japan, Earthquake Sequence

Published: September 2019

The 17 June 2018 MJMA 6.1 (Mw 5.5) Osaka earthquake exhibits a large non–double‐couple component (∼26%), and its aftershock sequence shows a complicated spatial pattern. To better understand the ruptured faults, we relocate the earthquake sequence using P and S arrival times and waveform cross correlations and calculate the focal mechanisms of all MJMA≥2.5 (Mw≥2.3) earthquakes within three months after the mainshock using P‐wave first‐motion polarities and S/P amplitude ratios. Relocated aftershocks image several faults, the northeast‐striking strike‐slip fault, the north‐northwest‐striking reverse fault, and at least two small northwest‐striking features. P‐wave first motions of the mainshock indicate nearly a pure thrust mechanism. We deduce that the earthquake sequence started from a north‐northwest‐striking reverse fault and propagated to a northeast‐striking strike‐slip fault. The aligned strike‐slip aftershocks occurring in the vicinity of the northeast‐striking strike‐slip fault delineates the growth of several newly formed or reactivated northwest‐striking Riedel shears that are conjugated to the northeast‐striking strike‐slip fault.

Localization of Laminin and Fibronectin in Rat Testes after Diisobutyl Phthalate Exposure: Histopathologic and Immunohistochemical Study
Authors: BAŞIMOĞLU KOCA Yücel
Published: September 2019

In this study the effects of Diisobutyl phthalate (DIBP) from
commonly used pytalates were histopathologically investigated in order to find out whether it is one of the
causes of increased infertility in recent years. In addition, the localization of laminin and fibronectin was demonstrated
immunohistochemically after exposure to DIBP. For this purpose, three study groups from Wistar albino rats were created: experimental group, control
group and corn oil applied group. The experimental group were administered by
gavage 3 different doses (0.25-0.5-1 ml/kg/day) of DIBP mixed with corn oil
every day for 28 days. At the end of the experiment, the testis tissue samples
from all of the experimental and control group animals were investigated and
evaluated with a light microscope after routine histological and immunohistochemical
preparation processes. Reduction in spermatogenic
cell population, apoptotic and necrotic germ cells, increase in Sertoli cells, multinucleate giant cells, thickening and
dilatation in basal lamina of seminiferous tubules, oedema and shrinkage in
interstitial connective tissue were
observed in DIBP treatment groups. The decrease
in localization of fibronectin and laminin immunoreactivity in seminiferous
tubules was observed. The
results of this study demonstrated that DIBP causes serious damage to the
testicular tissue, especially in terms of spermatogenesis. For this reason, it has come to the conclusion that the material
in question may cause infertility in male individuals.

Effects of Preoperative Glucose (Dextrose/Carbohydrate) administration via Intravenous versus Oral Route on Recovery Outcome in the Post-anesthesia Care Unit
Authors: Jablameli Mitra , Nazemroaya Behzad , Salehfard Ladan
Published: September 2019

Background: Human body exposure to any trauma, such as surgical procedures stimulates neurohumoral and catabolic responses. This process includes; increased metabolism of proteins, carbohydrates, and lipids along with water and sodium retention, resistance to insulin, and furthermore, increased levels of blood sugar. One of the factors that has been assumed to influence postoperative complications is preoperative fasting duration.
Methods: In this double-blind, randomized clinical trial, 90 patients aged 18 to 70 years, referred for elective surgery were randomly allocated to three groups of 30. Group A (IV-CHO): Within 6 hours of fasting, this group was treated with one gram per kilogram of carbohydrate dissolved in 50 ml of normal saline and then injected. Group B (Oral-CHO): Within 6 hours of fasting, this group was treated with one gram per kilogram of carbohydrate dissolved in 50 ml of normal saline and then administered orally. Group C (Ni-CHO): Within 6 hours of fasting, 50 ml of normal saline was administrated orally in this group. Patients were requested to score their pain following the surgical procedure using a scale of 0-10 scoring (VAS). Besides, the [need for] analgesics before [transfer] to the general ward, at the end of recovery stay were recorded as well.
Results: According to the results of our study, evaluation (and) comparison of VAS scores was significantly different among groups prior to the surgical procedure (p=0.004). Postoperative pain assessments showed significant difference among groups (p=0.002). Scheffe test showed significantly less pain score in the IV-CHO group than the oral-CHO (p=0.029) and control group (p=0.010).
Conclusion: Preoperative use of carbohydrate whether intravenously or orally could efficiently affect postoperative adverse effects in a positive manner while some aspects were not statistically changed to a more desirable status.
Comparison Immediate and Acute Adverse Effects Following Transforaminal Epidural Steroid Injections with Dexamethasone and Diluted Triamcinolone
Authors: Hosseini Behnam , Baghizadeh Fereshteh , Seyed Alshohadaei Seyed Mohammad , Ehsanpour Elahe , Qoreishi Mohammad
Published: September 2019

Background: Transforaminal epidural steroid injections (both lumbar and cervical) are used in many treatments. The use of this method in the control and treatment of radicular pain is intensively expanding. In this method, and for the purpose of implementing the injection process, the needle is inserted from the posterolateral of the spine and steroids injected.
Steroids include a wide range of medications, many of which are used in modern medicine. Research on these drugs is still underway. The use of Dexamethasone in lumbar transforaminal epidural injections and the study of complications caused by it have been less studied. In some previous studies, use of this steroid for lumbar transforaminal epidural injections has been mentioned.
Methods: The present study was conducted in Shohada-e-Tajrish Hospital in Tehran. Patients over 18 years of age who were afflicted with Lumbar stenosis Foraminal (Diagnosis by MRI) and had associated with Radio Kevlar pain were selected. These patients are divided into two groups of 14. In a group, 2.5 cc dexamethasone 8 mg / cc diluted with 2.5 cc distilled water was injected. In the second group, 2.5 cc triamcinolone 40 mg / cc was injected with 2.5 cc distilled water in a volume of 5 cc. In order to evaluate and compare the effects of these two steroids on the patients, the results of the questionnaire were evaluated by statistical techniques and software SPSS 21.
Results: The results showed that the use of dexamethasone had far more successful effects than another drug. However, the above conclusion is a relative conclusion and absolute expression is not possible. Pharmaceutical manifestations are the result of patient reactions. Thus, doing similar research and comparing drug performance should be put on the agenda of various research and medical teams.
Conclusion: Use of Dexamethasone had far more successful effects than Triamcinolone on epidural steroid injections.
The unlikely legalization of medical cannabis in Albania: a case study
Authors: Vyshka Gentian
Published: September 2019

Cannabis abuse has been an issue of major concern for the Albanian society in recent years, following the wide illegal planting of the species. Legal lacunas, weaknesses from the drug-controlling agencies, and the easiness of harvesting Cannabis sativa plants have contributed to the creation of a general negative opinion toward a potential use of its active principles for medical purposes. Professionals of the field and policymakers are largely focused on harm reduction activities, thus bypassing the option of legalizing cannabinoids for clinical conditions that might find relief in their use. The discussion of a case suffering from postherpetic neuralgia shows how this negative opinion is depriving Albanian patients from an otherwise helpful pharmacological option whose efficacy has been confirmed by an important bulk of research. Uncovering the roots of this misperception will help address the issue. Clinicians with expertise need to have their say in the debate, since for the majority of countries where medicinal cannabis is legalized, this was due to consumer-led initiatives. Ensuring patients’ freedom as implied within the principle of autonomy is also a sound ethical support of such legalization.

Authors: Bazrafkan Leila , Hayat Ali Asghar , Tabei Seyed Ziaaddin , Amirsalari Leila
Published: September 2019

Today, role modeling is an essential component of medical education that facilitates the students' learning and affects their attitudes and behaviors. Hence, this study aimed to examine the characteristics of positive and negative role models using a mixed method approach. In the quantitative part, data were collected using a questionnaire with 24 items. The research population included medical students who were in their clinical period between May 2017 and December 2018 at Shiraz University of Medical Sciences (n = 750). A total of 282 questionnaires were completed by these students, and in the qualitative part, 26 semi-structured interviews were conducted with them. The most important components of role modeling for students included: individual characteristics, clinical skills and competence, teaching skills and professionalism, in that order. The qualitative analysis confirmed the results of the quantitative analysis. The findings showed that the characteristics of a negative role model can also be classified in four main components. The results demonstrated that 46.8% of the students identified one or more medical teachers as negative models. Students paid attention to not only the positive characteristics of their teachers, but also their negative features, stating that they had been influenced by both. Therefore, it can be concluded that clinical teachers should improve their performance as positive role models through reducing these negative effects and reinforcing positive characteristics
O SAGRADO EM PRETO E BRANCO: UM RECORTE DA FESTA DE SÃO BENEDITO
Authors: Netto Helio Figueiredo da Serra
Published: September 2019

A festa de São Benedito, conhecida como Marujada, ocorre todo mês de dezembro na cidade de Bragança no estado do Pará. Uma das características estéticas desse evento se manifesta na vestimenta dos devotos, conhecidos como marujos. O chapéu peculiar, a roupa branca, os pés descalços e os detalhes em vermelho (ou azul), criam a identidade dessa manifestação e constituem-se como uma expressão imagética única. Ainda que as cores sejam predominantes nessa manifestação cultural, chamando a atenção de grande parte das pessoas que participam da festa, o objetivo deste artigo foi construir uma narrativa fotográfica que fosse além das cores e, ao se construir imagens em preto e branco, procurou-se captar o mais profundo da festa: a relação com o sagrado. Este artigo é um desdobramento de tese de doutorado que buscou refletir sobre a relação com o excesso tecnológico que vivenciamos hoje e como certas imagens podem nos redimir da violência nele embutida. Todas as imagens são de autoria do titular do artigo e foram construídas na Marujada do ano de 2015.

El presente artículo de reflexión, derivado de una investigación en torno a alfabetización académica y sus implicaciones en la formación del profesorado, indaga por las posibles formas y funciones del miniensayo, género discursivo que en la actualidad se abre paso como opción didáctica en el ámbito de la producción de textos argumentativos. A partir de definiciones del ensayo, reconocidas ampliamente por la tradición académica, arriesga diversas conjeturas respecto del miniensayo como forma híbrida en la que se expone y argumenta, desde el propósito de sentar bases para la defensa de una tesis. Asimismo, explora sus posibles funciones, en el marco del docere, movere y delectare. Estos acercamientos, fruto de intervenciones de orden cualitativo desde el diseño de la investigación acción, responden a una preocupación didáctica que advierte en el miniensayo, tanto un género para enseñar a argumentar, como una estrategia de escritura que posibilita un diálogo entre conceptos clave como tema y rema, voz propia y voz ajena, logos y pathos, convencer y persuadir.
Twórczość dominikanina Gabriela Zawieszki. Początki konceptyzmu w polskim kaznodziejstwie
Authors: Kuran Magdalena
Published: September 2019

Artykuł przedstawia twórczość dominikańskiego kaznodziei Gabriela Zawieszki (? – 1649). Każdy z jego sześciu zbiorów kazań podporządkowany jest tytułowej metaforze, która (mniej lub bardziej) wyznacza kształt inwencyjny i kompozycyjny poszczególnych tomów, pojedynczych kazań i argumentów. Leopolita jako pierwszy polski kaznodzieja tak świadomie i szeroko zastosował koncept w kazaniach i całych zbiorach, łącząc go w wielowymiarowym wykorzystaniem w egzegezie sensu duchowego. Podobny sposób formowania zbiorów kazań spotykamy w Polsce dopiero w drugiej połowie XVII wieku.
Postaci kobiece w sztukach jezuickich od połowy XVIII wieku – na wybranych przykładach
Authors: Mieszek Małgorzata
Published: September 2019

Artykuł omawia wybrane sztuki jezuickie z połowy XVIII w., w których występują postaci kobiece, wbrew przyjętym pod koniec XVI w. regułom (Ratio studiorum). Analiza utworów poprzedzona została rozważaniami teoretycznymi na temat stosunku jezuitów do ról kobiecych. Przypomniano wypowiedzi teoretyczne o charakterze polemicznym, wstępy dramaturgów do tragedii, w których uzasadniali oni brak postaci kobiecych. Analiza pokazała, że bohaterkami sztuk kolegiackich mogły być alegorie, personifikacje czy postaci mitologiczne. Ich działania stanowiły najczęściej symboliczny komentarz do akcji głównej dramatów. Prześledzono też zabiegi autorów tłumaczących obcojęzyczne dramaty na język polski, mające na celu dostosowanie pierwowzorów do wymogów scen kolegiackich. Znaczną część artykułu wypełnia analiza kilku tekstów, w których pojawiły się role żeńskie. Ukazano celowe zabiegi dramaturgów polegających na uwznioślaniu postaci kobiecych oraz konstruowaniu ich w oparciu o schematy znane z ról męskich.
The Investigation of Relations Among Self-Efficacy in Adolescents, Self-Perception of Parental Role and Adolescentsâ€™ Subjective Well-Being
Authors: Ozden-Yıldırım Melis Seray
Published: September 2019

Self-efficacy refers to beliefs about oneâ€™s capabilities to learn or perform behaviors at different areas such as academic, social and emotional. Thereby self-efficacy in adolescents can be related with their subjective well-being, defined as a personâ€™s cognitive and affective evaluations of his life. The second important factor that can be related with adolescentsâ€™ subjective well-being is their parentsâ€™ self-perception of their parental roles on the level of competence, role satisfaction, investment and role balance. On this basis the aim of this study is to investigate the relations among self-efficacy in adolescents, self- perception of parental role and adolescentsâ€™ subjective well-being. The research group was conducted by 390 adolescents aged between 12 and 17 and their parents. Data was collected with Demographical Information Form, Self-Efficacy Scale for Children, Self-Perception of Parental Scale and Adolescent Subjective Well-Being Scale. The findings indicated that academic self-efficacy, social self-efficacy, emotional self-efficacy and competence of mother were predicting adolescentsâ€™ subjective well-being significantly.

Authors: Kim Byeung-Seok , Moon Kang-Hoon , Kim Kang-Hoon , Lim Jong-Seon
Published: September 2019

The sensitivity of DNBR values to approaches of subchannel control volume selection has been investigated for the TS01 and TS03 out of HIPER17 CHF tests. In rod bundle analysis, most of the subchannel analyses used the coolant-centered subchannel nodal layout. But, it has been known that the rod-centered subchannel analysis showed good results for high quality critical heat flux. In this study, it was demonstrated that the rod-centered subchannel analysis showed more effective and conservative results than the coolant-centered subchannel analysis with the DNBR value, the quality, and the mass velocity. Also, it was verified that when the both results yielded from each subchannel analysis were compared, the subchannel locations at which DNBR occurred were similar.
Study on Spontaneous Combustion Tendency of Coals with Different Metamorphic Grade at Low Moisture Content Based on TPO-DSC
Authors: Fan Jiuyuan , Wang Gang , Zhang Jiuling

In the environments of all kinds open coal storage sites , mining-affected coalbeds, and goafs, parts of coal body at low moisture content (≤8%) are prone to spontaneous combustion under the influence of some external environmental factors. In order to examine the influence effect of low moisture content on the spontaneous combustion tendency of coals with different metamorphic grade, we conducted temperature programmed oxidation (TPO) experiment and differential scanning calorimetry (DSC) experiment to study the spontaneous combustion characteristics of coals with different metamorphic grade at four different low moisture content, and comparatively analyzed the change laws of the characteristic parameters of four different metamorphic grade coals at four different low moisture content. The experimental results indicate that: 1) Compared other low moisture content, anthracite and fat coal at low moisture content of 1.2% show stronger tendency to undergo spontaneous combustion, long flame coal and lignite at low moisture content of 3.4% and 5.6% are more prone to spontaneous combustion. 2) Four different metamorphic grade coals at low moisture content of 7.8% are less prone to spontaneous combustion; 3) Coals with different metamorphic grade have different tendency to undergo spontaneous combustion.

This paper proposes a Case-Based Reasoning (CBR) system to contribute to reinforce the sustainable performance of an environmental management system. The CBR system aims to support the decision-making process to select environmental management actions aimed at reducing risky trends of the environmental state of a region. The CBR system takes advantage of a set of situation-solution pairs called cases, which are stored in a memory and then retrieved as candidates to solve new problems. Situations in this work are represented by a set of risky trends of the following key environmental variables: CO2 emissions, Air-Quality, Loss of Vegetation Cover, Water Availability, and Solid Waste, whose combination damage the environmental state quality of a region. Meanwhile, solutions are represented by a set of environmental management actions. Similar situations to a given current situation are retrieved from the memory of cases and then their solutions are combined, through an adaptation mechanism, until the solution of the current problem is obtained. We used risky trends derived from real data related to the environmental states of a Mexican region to test the proposed CBR system. The results obtained provided insights into the potential of CBR systems to support the decision-making process to select environmental management actions aimed at reducing risky trends of current environmental states.

Traditionally, studies on freeze–thaw erosion have used the analytic hierarchy process (AHP) to calculate the weight of evaluation factors, however, this method cannot accurately depict the fuzziness and randomness of the problem. To overcome this disadvantage, the present study has proposed an improved AHP method based on the cloud model to evaluate the impact factors in freeze–thaw erosion. To establish an improved evaluation method for freeze–thaw erosion in Tibet, the following six factors were selected: annual temperature range, average annual precipitation, slope, aspect, vegetation coverage, and topographic relief. The traditional AHP and the cloud model were combined to determine the weight of the impact factors, and a consistency check was performed. The comprehensive evaluation index model was used to evaluate the intensity of freeze–thaw erosion in Tibet. The results show that freeze–thaw erosion is extensive, stretching over approximately 66.1% of Tibet. The problem is the most serious in Ngari Prefecture and Nagqu. However, mild erosion and moderate erosion, accounting for 37.1% and 25.0%, respectively, of the total freeze–thaw erosion are the most widely distributed. The evaluation results for the freeze–thaw erosion was confirmed to be consistent with the actual situation. In brief, this study provided a new approach to evaluate the conditions of freeze–thaw erosion quantitively in Tibet.

Plants Microbial Fuel Cells (PMFC) is a new technology that generates electricity in a renewable, clean and sustainable way. In spite of these advantages, it still faces limitations in power generation and current density, reaching lower production values than other renewable technologies. Different studies maintain that the high resistivity of the cathode is the main limitation in the generation of energy; therefore, non-metallic materials to obtain a better performance are replacing the metallic electrodes. The implementation of these materials applied to PMFC requires a complex interdisciplinary work. Through three experimental tests using metallic electrodes for the extraction of electrons, this research study shows that the treatment of the substrate with natural materials, the volume plant roots, and substrate temperature and humidity control have a significant influence in the increase of the electric potential and the generated current.

Hybrid Methods for Analysis of Fractured Well Production from Liquids Rich Duvernay Shale
Authors: Mahadevan Jagannathan , Hu Huanzhen
Published: September 2019

Objectives/Scope: In order to maximize the recovery of hydrocarbons from liquids rich shale reservoir systems, the cause and effect relationships between production and the stimulation methods need to be clearly understood. In this study, we integrate a production data regression approach with flow simulation methods to understand the fractured well production behavior and field wide well performance in a liquids rich petroleum system in the Duvernay Basin.

Methods, Procedures, Process: Statistical models assume no physical relationship between the model parameters and the response variable, which in this case is produced volumes over a period of time. On the other hand, simulation studies incorporate physical mechanisms of flow to model and predict the production behavior. The simulation models, however, fall short of incorporating all the mechanisms contributing to the production behavior in the complex shale gas reservoir. Thus there is a need for integration of statistical approaches of understanding production behavior along with physics based model and simulation approach.

Results, Observations, Conclusions: Multivariate linear regression analysis of the 6 month produced volume and its relationship with parameters such as fracture fluid volumes used, proppant weight placed, and number of stages fractured provides a model with reasonably good correlation. The 6 month produced volumes correlate with large proppant weights, lower fluid placements and greater density of fracture stages. Use of Random Forests machine learning algorithm on the dataset confirms that the total proppant placed, well length completed with fractures have high importance coefficients. In order to examine the well performance using full physical models, fractured well simulations were performed on particular wells using the trilinear model. The trilinear model predictions were compared against other production analyses and the regression model results for consistency. The models showed that in the absence of stress dependent permeability, the production forecast was much higher. Thus, stress dependent permeability appears to be an important factor in the modeling and prediction of production from liquids rich shale reservoirs.

Novel/Additive Information: In this study we describe a method to understand the production data from a liquids rich shale reservoir, by integrating multivariate linear regression analysis, machine learning algorithms along with physical model simulations. The results are novel and offer a method to validate either approach to understand cause and effect relationships. This approach may be classified as a new hybrid modeling approach that may potentially be used to optimize stimulation techniques in liquids rich shale reservoirs.

Considering the non-uniform steam conformance of conventional horizontal well, dual-pipe steam injection technique has currently demonstrated technical potential for improving heavy oil recovery. It can delay the occurrence of steam fingering and homogenize the steam injection profile along horizontal wellbore. But in some field tests, it is observed that the results were far greater than such an approach would have justified. In addition, the actual physics are still unclear, and not demonstrated. In this paper, first, we built a cylindrical wellbore physical model to experimentally study steam injection profiles of a single pipe horizontal well and a concentric dual-pipe horizontal well. Thus, the heat and mass transfer behavior of steam along horizontal well with a single-pipe well configuration and a dual-pipe well configuration was addressed. Subsequently, considering the effect of pressure drops and heat loss, a semi-analytical model for the gas-liquid two-phase flow in horizontal wellbore was developed to numerically match the experimental observation. Next, a sensitivity analysis on the physical parameters and operation properties of a steam injection process was conducted. The effect of the injection fluid type was also investigated.

Experimental results indicated that under the same steam injection condition, an application of the dual-pipe well configuration can significantly enhance the oil drainage volume by about 35% than the single-pipe well configuration. During the experiments, both a temperature distribution and liquid production along the horizontal wellbore were obtained. A bimodal temperature distribution can be observed for the dual-pipe well configuration. From this proposed model, an excellent agreement can be found between the simulation results and the experimental data. Because of the effect of variable-mass flowing behavior and pressure drops, the wellbore segment closed to the steam outflow point can have a higher heating radius than that far from the steam outflow point. From the results of sensitivity analysis, permeability heterogeneity and steam injection parameters have a tremendous impact on the steam injection profile along wellbore. Compared with a pure steam injection process, the co-injection of steam and NCG (non-condensable gas) can improve the effective heating wellbore length by over 25%. Furthermore, this model is also applied to predict the steam conformance of an actual horizontal well in Liaohe oilfield. This paper presents some information regarding the heat and mass transfer of a dual-pipe horizontal well, as well as imparts some of the lessons learned from its field operation. It plays an important role for the performance evaluation and remaining reserve prediction in a dual-pipe thermal recovery project.
