Aims: The aim of this study was to evaluate the presence of Porphyromonas gingivalis (Pg) the in subgingival biofilm, as well as to compare the immune responses of postpartum women and their newborns to Porphyromonas gingivalis using antibody serum levels.Methods: A total of 43 postpartum women and 24 newborns were selected in the municipal maternity hospital of Alagoinhas, Bahia, Brazil between February and December 2003, for this cross-sectional study. The presence of Pg was verified using polymerase chain reaction. The immunoglobulin serum levels: IgG1, IgG2, IgG3, IgG4 and IgA, reactive to Pg ATCC33277, were tested using ELISA. Results: 39,3% of the postpartum women biofilm samples were positive for Pg. The incidence of the pathogen in the women with periodontitis (70%) was higher than in the group of women without periodontitis (30,30%). Among the newborns, high serum levels of IgG4 anti-Pg were observed (p<0.001).Conclusion: Our findings confirm that postpartum women with periodontitis present remarkable incidence of Porphyromonas gingivalis which may influence systemic response, as represented by high levels of serum antibody levels against this pathogen in women and newborns. Furthermore, evidence suggests that some antibodies crossed the placental barrier in newborns.

Unified Model of Heat Transfer in Gas/Oil/Water Pipe Flow
Authors: Zheng Wei , Zhang Hong-Quan , Sarica Cem 
Published: September 2016

Abstract
In oil and gas production, the heat transfer process occurs from reservoir porous media to surface facility. Accurate modeling of convective heat transfer coefficient of pipe flow will improve production facility design and help tackle flow assurance problems such as gas hydrates, scale, wax deposition, heavy oil production and transportation. This paper presents a unified gas/oil/water heat transfer model for pipe flow at inclinations from −90° to +90°. It provides a new approach to three-phase pipe flow mechanistic heat transfer modeling.
In this approach, three-phase hydrodynamic parameters were calculated first using Zhang and Sarica (2006) unified model. Then, the heat transfer models were developed for gas/oil/water three-phase flow patterns. The phase distributions were described as gas/liquid flow pattern and oil/water mixing status. Energy balance, temperature differences and variations were analyzed for each case. Overall heat transfer coefficients were derived and programmed. To test the program implementation, a synthetic field case was created and run. The temperature prediction was reasonably compared with commercial steady-state and dynamic multiphase flow simulators. The gas/oil/water heat transfer model was then compared with an oil/gas two-phase experimental data from Manabe (2001) for different flow patterns in a 52.5-mm inner diameter pipe from horizontal to upward-vertical inclinations. Overall performance of the present model was good. Convective heat transfer coefficient prediction was within 22% absolute average relative error. Mixture temperature was predicted within 1.5% absolute average relative error. After comparing with two-phase flow data, sensitivity of heat transfer coefficient to water cut was analyzed by changing the water cut from 0.0 to 1.0 under different flow conditions. Predicted convective heat transfer coefficient was sensitive to flow pattern, water cut and flow rate changes. Generally, the predicted convective heat transfer coefficient increases as water cut increases for the same flow pattern.

AbstractParaffin can be deposited in any part of the flow conduit. It can affect the flow in the borehole near formation, the downhole pump, the tubing, surface flow lines, separators, storage tanks and pipe lines. The use of Xylene or chemical products of aromatic nature can affect other components of the well completion using elastomers such as packers and artificial lift components, potentially compromising well integrity. This justifies a growing demand for environmental friendly Technologies for the removal of paraffin in oil field operation by means of non-toxic, non-carcinogenic, non-flammable, biodegradable products. As opposed to acidic products the action of the environmental friendly products requires the help of mechanical forces. This paper describes appropriate test procedures and laboratory set up to test the efficiency of the products prior to their field use. This requires that the test conditions reproduces the well and facility system. The presented set up further enables the concentration optimization of the recipe.Paraffin and mother oil samples have been tested in the lab in order to determine its potential for use in the field. Environmental friendly paraffin removal products were selected that are non-toxic, non-flammable and non-carcinogenic. The elaborated set up and test procedure enables identification of the most effective product and to optimize its concentration.In the first phase of this evaluation Dispersants based on biodegradable Surfactants are tested. Further investigation on second phase will focus on Wax Cristal Modifiers such as Polymers. For both phases the multipurpose properties of the chemicals will be evaluated.The presented phase wise investigative approach supports a workflow that effectively encourages the participation of everybody in the organization in the introduction of new innovative ideas and Technologies thus contributing a continuous improvement mode and a shift to an innovations friendly organization.

Published: September 2016

Abstract
Due to the high temperature, high pressure and sophisticated chemical environment in heavy oil wells, Steam-Assisted Gravity Drainage (SAGD) is considered one of the most challenging service conditions for carbon steel equipment. This paper introduces an advanced metal-metal bonded coating technology-electroless nickel (EN) coating and its applications in SAGD operations to protect downhole equipment from fouling due to corrosion, adhesion of inorganic and organic materials as well as the impacts of wettability alteration. In the first chapter, we will describe the complex and hostile thermal-chemical environment, their impacts on the SAGD production system and the fouling causes. We will compare the performance of EN coating to that of regular carbon steel pipe in the following aspects: a) corrosion resistance in the presence of sour gases using potentiostatic and potentiodynamic polarization methods; b) adhesion of silica, bitumen coated silica using atomic force microscopy, and c) surface energy and wettability alteration using contact angle measurements. The set-up of the facility, procedures of the tests and governing science and engineering principles will be reviewed. In the end, we will introduce the results of laboratory and SAGD field experiments designed to investigate the EN coating technology in protecting the substrate materials under SAGD conditions.
Enhanced Production with ICD and AICD Completions in Oil Wells: Case Studies From Latin America
Authors: Porturas F.. 
Published: September 2016

Abstract
Well completions in Latin American oil and gas fields are characterized by many challenging conditions, including reservoir traps with high structural and sedimentological complexity, diverse hydrocarbon reservoir fluids and rock properties, as well as fluid PVT properties and wettability characteristics that vary regionally within a reservoir. In addition, production units on land, offshore and particularly in deepwater environments have limited gas and water treatment capabilities. Accordingly, the objective of many assets is to produce at the lowest possible gas-oil ratio (GOR) and water cut (WCUT).
Horizontal wells are often completed with conventional slotted liners. Historical production data confirmed by several production logs indicate that a vast number of wells are under-performing due to non-uniform reservoir influx along the wellbore. This results in early water or gas coning and uneven reservoir drainage that leaves valuable bypassed oil in the ground. To compound the issue, the rapid production increase of highly mobile fluids such as water or gas generates high operational costs for fluid treatment, re-injection, and disposal.
Previous publications have explained Inflow Control Devices (ICD) and Autonomous Inflow Control Devices (AICD) principles and design. This paper present and describes examples of successful inflow control device installations in oil well producers in Latin America; installed to produce oil while restricting unwanted water in heavy oil reservoirs. A few variation of inflow control types covering a wide rnage of oil viscosities from 0.6 to 1000+ cP and rock properties and installations in already pre-installed screens to minimize water and gas entry, balance GOR, pressure drawdown aimed to re-vitalize mature fields.
ICDs and AICDs technologies have shown robustness and production performance, reducing high water production at a well, group or field level, extending production life and reducing production costs by minimizing the risk of handling unwanted fluids at the surface and leaving bypassed oil underground.
Experimental and Numerical Simulation of Combined Enhanced Oil Recovery with In Situ Upgrading in a Naturally Fractured Reservoir
Authors: Chavez-Morales Silvia , Pereira-Almao Pedro 
Published: September 2016

Abstract
The purpose of this research work is to show laboratory experiments conducted at 1500 psi and 350°C, experimentally simulating a reservoir located in the Gulf of Mexico. The experiments conducted used a novel process that involved a hot fluid to be injected with an ultra-dispersed nano catalyst. The results obtained showed that API gravity can be improved permanently as well as its viscosity, with the advantage of no coke or solid deposits formation. Laboratory analyses showed that by using this new process it is possible to enter into the matrix zone, expelling at least partially the oil confined inside.
As a consequence of the temperature increase, matrix rock may expand and expel its oil; while temperatures decrease, the pores in the matrix could be contracted, generating additional oil expulsion from this area. As a consequence of this expansion-contraction in the reservoir the reserves could be increased. Also, a change in the permeability appears due to the temperature increases.
The present study was focused in oil matrix extraction and in situ oil upgrading from a naturally fractured reservoir of heavy oil as a result of a hot fluid injection with nano catalyst. Moreover, the effects of capillary pressure, mobility, viscous effects, wettability, and gravitational drainage on the process were analyzed. Another aspect that was studied is how the thermal expansion generated as a consequence of the process that could expel the oil confined in the matrix.
Theoretical orientation and validity of observation in sociology and anthropology
Authors: Ilić Vladimir 
Published: September 2016

This article discusses closely related issues of the theoretical orientation and the validity of the application of the method of observation in sociology and anthropology. It was preceded by a text which discussed issues of meeting the principles of objectivity, systematicity and reliability when using observation as a research method. General problem of the relationship between theory and research in the application of observation will be analyzed in the subsequent article.
Introductory section shows the general framework of a hypothetical - deductive conception of science and the role of the method of observation in this context. The next section of the article analyzes the effort of finding denying cases and discusses the limits of the method of analytical induction. This section deals with the influence of data analysis in qualitative form obtained by (usually participatory) observation and constructing explanations on the validity of the observation. The next section of the article shows the possibility of increasing the validity of the observation by including other sources and methods of data collection. The final section shows the impact of over-emphasizing the epistemological difference between qualitative and quantitative orientation in sociology and anthropology on the possibility of increasing the validity of the observation as a research method.
Archaeological Exhibitions in Serbia: Foundations of Museum Archaeology
Authors: Cvjetićanin Tatjana 
Published: September 2016

Although every local museum or parts of national museums keep archaeological finds, museums in general play a very limited role on the archaeological scene, often being passive and marginalized. Well-grounded investigation into the archaeological objects kept in museum collections and, above all, the public domain of museums, the nature of collections and exhibitions, both permanent and occasional, have not been adequately recognized, discussed or considered. In spite of the fact that museum exhibitions legitimize the dominant social and political norms of the present, museums remain marginalized, separated from the currents of various pertinent disciplines, and not prepared for the necessary changes. Archaeological theory, shaping the archaeological practice of museums as well, is not understood as its constituent part, and the interpretive context in which exhibitions are created, contents and nature of interpretation are not considered.
The analysis of the exhibitions of the National Museum in Belgrade, being the paradigm of museum archaeology in Serbia up to the middle of the 20th century, has shown that the culture-historical approach, the idea of continuity and dynamic artistic presentations of alienated past have marked this public presence of museums. The Museum has developed from the storage space and knowledge presentation, over exhibition space to an ideal museum, dominated by estheticized expositions, establishing various official representations of the past. The changes in the theory of museology, somewhat coinciding with the changes in archaeological theory, have posed a new challenge to museum archaeology, that may be defined in short as the need for the new interpretation of the past.

Published: September 2016

The issues on objectification and selection of indications for conservative treatment of intestinal intussusception in children remain to be disputable.Materials and methods. The experience of treating 249 pediatric patients (172 boys and 77 girls) with intestinal intussusception at the age of 2 months - 13 years was analyzed. There were 265 cases of intestinal intussusception including 16 cases of the recurrence in 11 children. Conservative treatment was performed in 178 (71.5%) children, 71 (28.5%) children were operated on. To make the analysis, children were divided into 3 groups according to three ten-year periods.Results and discussion. The statistical analysis demonstrated the decrease in the number of patients with the increase in the number of children over 1 year of age over the past decade. The 1st decade was characterized by the introduction and experimental substantiation of flow-through pneumatic insufflation developed by the author with following refusal of X-Ray control. The methods of objectification of the criteria for non-surgical reduction of intussusception using flow-through pneumatic insufflation were developed experimentally. In the 2nd decade the algorithm for treatment of intestinal intussusception was developed; the indications for non-surgical reduction of intussusception were extended. 5 (22.7%) children out of 22 with disease duration of more than 24 hours and 6 (46.2%) children out of 13 over 1 year of age underwent non-surgical reduction of intussusception. In the 3rd decade the indications for non-surgical reduction of intussusception were extended. 11 (57.9%) children out of 19 with disease duration of more than 24 hours and 20 (74.1%) children out of 27 over 1 year of age underwent non-surgical reduction of intussusception. Only in 4 (28.5%) children out of 14 over 1 year of age who were operated on, we found out anatomical cause of the condition. We have analized the experience in treating 11 children with 16 recurrences of intestinal intussusception. In 7 cases non-surgical reduction was performed, 4 children were operated on. During surgeries there were observed no anatomical causes or predispositions to intussusception. Lethal outcomes were not registered.Conclusions. Thus, flow-through pneumatic insufflation is an effective and objective technique of non-surgical reduction of intestinal intussusception in infants. Non-surgical reduction of intestinal intussusception can be performed in the majority of patients without the signs of peritonitis. The duration of the condition, age of patients and the presence of recurrence should not be considered as absolute criteria in choosing treatment tactics in intestinal intussusception.

Работа посвящена изучению влияния различных схем интраоперационной коррекции артериального давления у пациентов пожилого возраста, оперируемых по поводу аортокоронарного шунтирования, на частоту возникновения послеоперационных когнитивных дисфункций. Материалы и методы. В исследование были включены 43 пациента с ишемической болезнью сердца, которым на базе ГУ «Институт сердца» МЗ Украины была выполнена операция аортокоронарного шунтирования. Средний возраст обследованных составлял 67,5 ± 2,3 года, средний вес — 87,4 ± 5,2 кг. Лиц мужского пола было 35 человек (81,4 %), женского — 8 человек (18,6 %). По способу коррекции интраоперационного повышения артериального давления (свыше 30 % от рабочего) все обследованные пациенты были разделены на две группы. В первую группу (n = 23) вошли пациенты, которым коррекцию проводили путем углубления анестезии. Во второй группе (n = 20) артериальное давление корректировали с помощью инфузии урапидила (Эбрантила). Результаты и обсуждение. Результаты теста на объем кратковременной слухоречевой памяти продемонстрировали, что на 7-е сутки после проведенной операции пациенты І группы набирали в среднем 13,6 ± 1,07 % в сравнении с аналогичными показателями у пациентов ІІ группы. Результаты теста на тонкую моторику рук также показали, что пациенты ІІ группы набрали 4,75 ± 0,12 %, что в среднем было больше на 33,9 ± 2,5 % относительно аналогичных значений у пациентов I группы. Таким образом, интраоперационное повышение артериального давления зачастую имеет многофакторные причины, и перед введением дополнительной дозы гипнотиков следует оценить глубину анестезии. А для коррекции повышенного артериального давления во время проведения общей анестезии следует использовать препараты с управляемым и прогнозируемым антигипертензивным действием.
Обґрунтування використання регіональної аналгезії для знеболювання в ранньому післяопераційному періоді у дітей з онкопатологією
Authors: Dmitriiev D.V. 
Published: September 2016

Дослідження проведені у 62 дітей віком 14,2 ± 4,2 року, прооперованих з приводу пухлин черевної порожнини — 24 (38,7 %) дитини, пухлин заочеревинного простору — 38 (41,3 %) дітей. Комплексне вивчення реакцій больової поведінки, фізіологічних показників і лабораторних стресових тестів показало, що використання схеми комбінованої регіональної анестезії бупівакаїном 0,375% та безперервною внутрішньовенною інфузією фентанілу в дозі 10 мкг/кг/год для післяопераційного знеболювання призводить до ефективної аналгезії після травматичних онкологічних оперативних втручань. Мультимодальна аналгезія — регіональна анестезія та безперервна внутрішньовенна інфузія опіоїдних анальгетиків покращує показники центральної та мезентеріальної гемодинаміки і, можливо, знижує ризик розвитку ускладнень у післяопераційному періоді та призводить до зменшення проявів гіпералгезії, а використання парацетамолу як додаткового знеболювання призводить до адекватного знеболювання та не впливає на розвиток гіпералгезії на відміну від наркотичних анальгетиків.
