Authors: Li Xin , Li Hongxia , Dong Wei , Qin Haiying , Xi Junhua , Ji Zhenguo
Published: August 2019

In this study, 3-dimensional nanoflower structured TiO2 photoanodes were successfully grown onto tin oxide doped with fluorine substrates. X-ray diffraction and scanning electron microscopy were performed. The 3-dimensional TiO2 nanoflowers presented improved photoelectrochemical performance compared with a TiO2 layer. Meanwhile, TiO2 nanoflowers with 2.5 h preparation time substantially increased the production of H2 compared with the TiO2 layer. The improved performance could be ascribed to the 3-dimensional nanoflower structure with many carriers and fast reaction kinetics, which enhanced light absorption and enlarged the contact area between the photoanode and electrolyte. Moreover, this nanoflower structure with trunks connected to the FTO substrate also improved the transfer of photogenerated carriers.

Authors: Li Bin , Chen Zhiyong , Ren Erzhou
Published: August 2019

Fractal theory is widely used to analyze the topography of surfaces; however, the relationship and characteristics of fractal dimension and microstructures of β-SiC films have not been reported. Using scanning electron microscopy and computer analysis, the microstructures of β-SiC films were evaluated; the films were prepared on AlN substrates by laser chemical vapor deposition using a diode laser and hydrido polycarbosilane as the precursor at different vacuum levels. The effect of vacuum level on the microstructure of β-SiC films was evaluated. The results show that the microstructures of β-SiC films exhibit the characteristics of fractals. Using the box counting method, the fractal dimensions of β-SiC films were calculated to be about 1.94–2.14, providing more fractal identification in evaluating the performance of films.
INVESTIGATION OF EXHAUSTING PHENOMENA OF GAS TURBINE ENGINE ON THE BASIS OF WAVELET ANALYSIS
Authors: Tkacheshak N. V. , Horbiichuk М. І.
Published: August 2019

The method for research of a gas turbine engine (GTE) surging phenomena based on wavelet analysis was developed. GTE DG-90 was chosen for research. A wavelet decomposition of the air pressure signal was carried out using a high pressure compressor and Dobeski, Symlet, Coffle and Meyer's discrete wavelet. The advantages and disadvantages of filtering properties of these wavelets were graphically represented in the form of amplitude-frequency characteristics. Based on the results obtained, a wavelet transform parameter selection scheme based on the analysis of the frequency response of wavelet filters was constructed, and the optimum sampling time of the wavelet filtering of the investigated signal was calculated for determination of the propagation and rotational breakdown in the GTE turbocompressor. According to this scheme, among the wavelets of Dobeski, Simlet, Koefleta, and Meyer's discrete wavelet, for studying the air pressure signal at the compressor during bursting processes, the first were selected by the Dobeches and Symmetes wavelets of the 2nd order according to their filtration rate. Considering high speed and characteristics of the description of the occurrence of excite phenomena by means of a fast Fourier transform to the distribution of the wavelet coefficients of the air pressure signal by turbocompressor, for the diagnosis of unstable flows occurring in the gas path of the gas turbine trajectory (surging and rotary breakdown), the Dobeski wavelet was selected 2nd order. At the same time, to monitor the wavelet coefficients behavior, the detail of the investigated signal is necessary at the 7th level of decomposition. Thus, the obtained results allow to carry out further analysis of breakdown processes using low-order wavelets.
SOLUTION OF THE MAIN DIFFERENTIAL EQUATION OF DEFORMATIONS OF THE CASING IN A CURVED WELL
Authors: Paliichuk I. I.
Published: August 2019

In a curvilinear well, the casing functions as a long continuous rod. It is installed on the supports-centralizers and replicates the complex profile of the well, as a result of which it receives large deformations. To describe them, a system of differential equilibrium equations of internal and external forces and moments was composed, which was supplemented to a closed form with a differential equation of curvature. It is non-uniform, because it takes into account the own distributed weight of the rod. Two ways are proposed to solve the problem: by the method of mathematical compression of the system equations into a complex inhomogeneous differential equation or by projecting the equilibrium equations of forces on the global (vertical-horizontal) and on the local (tangent-normal) coordinate systems. It is shown that the first integral of the system can also be found from the equilibrium equations of a portion of a curved rod of finite length. This integral has the form of a second-order inhomogeneous differential equation with variable coefficients and is the main equation that describes the deformation of a long elastic rod under the action of the longitudinal and transverse components of the forces of distributed weight. The main requirement of the technology is the installation of a pipes column on the centering supports, the purpose of which is to ensure the coaxiality of the pipes and the borehole walls and the creation between them a cement ring of the same thickness and strength. Accounting for this requirement allowed us to linearize the main equation. Its solution is the clue to the formulas of deflections, angular slopes, internal bending moments and transverse forces in the rod with the arbitrary arrangement of supports and boundary conditions in their intersections. The solution of the main differential equation of angular deformations of a long bar is found in the form of a linear combination of Airy and Scorer’s functions and in the form of three linearly independent polynomial series in the sum with a partial solution. The obtained formulas of flexure and power parameters allow us to calculate stress and strain in the pipes column during the process of casing the borehole of an arbitrary profile which increases the reliability and durability of the well.
IMPROVEMENT OF ROD STRING DRIVE ROTATOR
Authors: Kopey B. V. , Bilyk N. D.
Published: August 2019

At present, there is not enough literature on the study of effective methods of the pump rod cleaning from asphalt-resinous and paraffinic substances and salts using the rod string rotator. At present, no rotators have been developed that significantly reduce the wear of the sucker rod body, or can be applied to polymer composite rods.

The development of an effective rod rotor, ensuring continuous rotation of the rod string for cleaning of paraffin deposits. The choice of this method against APSD in the conditions of preserving the quality of products and implementation of normative and economic indicators in modern conditions is an important and topical issue.

The design of the rod string rotator is developed, ensuring continuous rotation of the rod string from an independent actuator. This rotator design modernization makes it possible to reduce the amount of wearable parts, ensures independence of rotation from the progress of the rocking machine, which makes it possible to rotate the column of the rod at moments when the walking beam is at the top or bottom point, the rotation is carried out smoothly and without jerks, because with a mechanical drive slight jerks (when the rod is in contact with the tubing)  is possible, the ease of replacing worn parts, inspection and replacement of the drive  could be implemented.

Using SolidWorks, a finite-element analysis was performed; a body and a cover are connected by means of transverse bolts with a torque, which creates a pulling force equal to 120 kN. From the data obtained, it can be seen that in attachment points of the cover to the body of the rotary screw with the help of bolts, there are slight tensions that are permissible for these materials.

An assessment of the rod string weight on the rotating body was performed. It has been established that the deformations that occur in the attachment points of the cover to the base are within the tolerance.

Thus, these improvements provide a continuous operation of the rotator to reduce paraffin deposition in the hole and reduce the wear of the rod and tubing. A finite-element analysis of the rotator is performed, which testifies to its efficiency at application of operational loads.

Published: August 2019

A study was performed to improve the performance of drill bits. It is noted the main work item are cones, equipped with serrated arms, made in the form of solid or false teeth. It is noted reinforcement of cutters during destruction of rocks is subjected to intensive wear under the action of high loads at the bottom, significant temperature differences, in the presence of abrasive particles, changes in the rock hardness. To reduce the impact of these factors on the wear of rock-destruction weapons, comprehensive design and technological measures are proposed to create a rock-destructive tool and, in particular, its reinforcement. The efficiency criterion of such events is proposed to choose resistance of rock-cutting elements to various types of wear. For implementation of the proposed approach to creating effective reinforcement, a critical analysis of the design of the cutter teeth of drill bits equipped with teeth of various designs and technologies for their manufacture was performed, and rolling cutters with plug-in teeth made by centrifugal reinforcement were selected as the object of research as the most optimal. The design of such teeth, implemented by a centrifugal casting process, provides for location of the rock-breaking hard alloy in the tooth head. The tooth root, pressed into the cutter housing, is made of steel. A mathematical model of the process of centrifugal reinforcement of cutter teeth of drill bits was developed to study the impact of process conditions on their resistance to impact-abrasive wear. As independent variables, otherwise the factors determining the technological process modes of centrifugal reinforcement were selected X1, X2, X3, X4, their main level and intervals of variation, the upper and lower levels were established. A full factor experiment 24 was used in the research. An experimental plan was drawn up. In accordance with the chosen plan, 16 active experiments were performed; each experiment was repeated three times. Then, a mathematical model and its describing regression equation were developed. The impact degree of process factors on the value of shock-abrasive wear of teeth and their optimum values were determined.

Published: August 2019

The aim of the current work was to elucidate whether the encapsulation of curcumin in nanoparticles (of microemulsion type) would allow its exertion of anticancer activity on several cancer cell lines or not. Curcumin microemulsion was prepared using the water dilution method, in which oleic acid constituted the oily phase, and tween 20, ethanol constituted the surfactant and cosurfactant respectively. The microemulsion was tested for its particle size, charge, morphology using transmission electron microscopy, in vitro curcumin release, stability and anticancer activity on HCT-116 colon cancer line, A549 lung cancer cell line, and PC3 prostate cancer cell line. The safety of the formulation was tested on fibroblasts cell line. Results revealed that curcumin microemulsion was successfully prepared with a particle size of 11.45±0.21 nm, and a negative charge of -9.07 mV, and it was able to sustain the release of drug for 24 hours with a cumulative percent released of 66.72%. Its spherical morphology was confirmed using transmission electron microscopy. No significant changes in particle size or charge were observed upon storage, suggesting the physical stability of the microemulsion. Curcumin microemulsion was proven safe on the normal fibroblasts cell line, and it preserved the anticancer activity of curcumin against A549, HCT116, and PC3 cell lines. Results of this study delineate that microemulsion is a suitable nanodelivery system for curcumin, which needs to be tested on animal tumor models for verification of the anticancer properties in vivo.

The hydatid cyst of the diaphragm is defined as the development of a hydatid cyst in the diaphragm muscle. Primary or secondary it stills a rare localization, accounting for 1% of the thoracic locations. We report a case of a hydatid cyst of diaphragm in a 57 -year-old female who was admitted to our clinic for right basithoracic pain. CT reported a giant hydatid cyst including multiple vesicles at the right lower thoracic cavity. Surgical exploration revealed an independent giant diaphragmatic hydatid cyst. We performed cystotomy and more than 100 daughter vesicles were removed from the cyst. The rest of the giant cyst cavity was excised.
The Urban Politics of Mega-Events
Authors: Lauermann John
Published: August 2019

This article reviews recent scholarship on the urban politics of mega-events. Mega-events have long been promoted as drivers of urban development, based on their potential to generate beneficial legacies for host cities. Yet the mega-event industry is increasingly struggling to find cities willing to host. Political arguments that promote mega-events to host cities include narratives about mega-event legacy—the potential for events to generate long-term benefits—and mega-event leveraging—the idea that cities can strategically link event planning to other policy agendas. In contrast, the apparent decline in interest among potential host cities stems from two political shifts: skepticism toward the promises made by boosters, and the emergence of new kinds of protest movements. The article analyzes an example of largely successful opposition to mega-events, and evaluates parallels between the politics of mega-events and those of other urban megaprojects.
Home and Away
Authors: Rahder Micha
Published: August 2019

This article examines the reinvigoration of outer space imaginaries in the era of global environmental change, and the impacts of these imaginaries on Earth. Privatized space research mobilizes fears of ecological, political, or economic catastrophe to garner support for new utopian futures, or the search for Earth 2.0. These imaginaries reflect dominant global discourses about environmental and social issues, and enable the flow of earthly resources toward an extraterrestrial frontier. In contrast, eco-centric visions emerging from Gaia theory or feminist science fiction project post-earthly life in terms that are ecological, engaged in multispecies relations and ethics, and anticapitalist. In these imaginaries, rather than centering humans as would-be destroyers or saviors of Earth, our species becomes merely instrumental in launching life—a multispecies process—off the planet, a new development in deep evolutionary time. This article traces these two imaginaries and how they are reshaping material and political earthly life.

Hematoma duodenal traumático.
Authors: Almada Mario , Martínez José , Muniz Nicolás , Misa Ricardo
Published: August 2019

Antecedentes: Las lesiones del duodeno se producen en alrededor del 3 al 5 % de las lesiones traumáticas abdominales. El diagnóstico es un desafío, especialmente en el traumatismo cerrado, porque la signosintomatología es inespecífica. La valoración inicial se centra en la identificación temprana de lesiones de alto grado asociadas con altas tasas de mortalidad. La mayoría de las lesiones del duodeno son de bajo grado y pueden ser de manejo conservador, pero lesiones más complejas pueden requerir cirugía. El objetivo es mostrar el caso de un paciente que presentó un hematoma duodenal traumático y su tratamiento.

Caso clínico: Paciente sexo masculino 27 años de edad ingresa por trauma abdominal contuso. Se presentó con dolor centroabdominal, náuseas y vómitos. Hemodinamia estable; exámenes de laboratorio normales. Tomografía computada (TC) abdominal mostró una obstrucción intestinal causada por un hematoma en la pared duodenal. Se realizó tratamiento conservador en base a descompresión gástrica, inhibidores de la bomba de protones intravenosa, nutrición parenteral y controles clínicos seriados, cursando una buena evolución.

Discusión: Se trata de una entidad infrecuente en los pacientes adultos. El manejo no operatorio en caso de hematoma duodenal traumático es efectivo y evita la morbimortalidad de procedimientos más complejos.

Sobre la ecología política posthumanista
Authors: Durand Leticia , Sundberg Juanita
Published: August 2019

En este trabajo describimos la emergencia y desarrollo de una nueva generación de estudios en ecología política conocida como ecología política posthumanista. A partir de una amplia revisión de literatura, trazamos sus principales influencias, sus temas centrales de análisis y las ventajas que aporta para comprender nuestra relación con el entorno, en un momento en el que es cada vez más difícil distinguir entre los dominios de lo social y lo natural. La ecología política posthumanista, hace uso de conceptos como ontología relacional, agencia más que humana y performación, útiles para superar definiciones limitadas de lo humano y asignar grados variables de agencia a lo no humano. El desarrollo de metodologías adecuadas es un reto importante en esta área, pero es necesario considerar que no se trata de mejorar nuestras representaciones de lo no humano, sino de experimentar el entorno de nuevas maneras. La ecología política posthumanista nos ofrece nuevas vías para pensar y explorar nuestros encuentros con lo no humano y, al mismo tiempo, para reflexionar sobre lo que, hoy en día, significa ser humanos.

No obstante, hombres y mujeres de las nuevas generaciones que se han erigido como agentes locales de cambio, están especializándose para encontrar distintas opciones tecnológicas que solucionen los problemas de la floricultura. Entre las acciones que se sugieren en este artículo está fortalecer la articulación de actores con intereses convergentes que promuevan diálogos y espacios de encuentro para hacer viable una floricultura sustentable.
Una aproximación a la economía política: riqueza natural y poder en Metztitlán, siglo XVI
Authors: Lorenzo Monterrubio Carmen , Vergara Hernández Arturo
Published: August 2019

El objetivo de este artículo es determinar los procesos económicos y políticos que tuvieron lugar en la región de Metztitlán en el siglo XVI. Se partirá del marco teórico de la economía política y en particular de su postura antropológica. Los postulados de los principales representantes de la antropología económica y política como Karl Polanyi y Morton Fried permiten reconocer la relación entre la economía y la política, la cual determinó el desarrollo de Metztitlán desde el periodo prehispánico hasta la implantación de la encomienda por parte de los primeros conquistadores. El caso de Metztitlán es sumamente interesante ya que, a raíz de la gran riqueza natural y económica de la región, comenzó a formarse un núcleo de poder que se centralizó en la figura del encomendero, quien se encargó de controlar los recursos naturales y humanos y ejercer un poder basado en la fuerza y la coerción para la extracción del tributo. Los postulados teóricos de la antropología económica y política se pueden aplicar a este caso, lo que nos permite no sólo describir los hechos históricos, sino también ofrecer una interpretación.

CORRELATION OF THE SHEDDING OF LYMPHOCYTES RECEPTORS WITH PARAMETERS OF IMMUNOLOGIC REACTIVITY IN RESIDENTS OF THE NORTH
Authors: Karyakina O E , Dobrodeeva L K
Published: August 2019

The study retrospectively investigated correlation characteristics of membrane and soluble forms of lymphocyte receptors in 78 healthy people living in the city of Arkhangelsk. The results of a statistical analysis allowed to evaluate the relationship of dynamic indices of shedding lymphocyte receptors CD23 and CD80 to the immunological reactivity indices. It was found that the receptors' shedding was not associated with the processes of proliferation and activation of immune cells, and the receptors abscission occurred by postmitotic mature cells. A high ratio reflecting the relationship of shedding activity of membrane forms of lymphocyte with cytokine IL-1 and IL-10 in the extracellular medium was a reflection of the biological processes regulating the in the form of feedback: increasing of receptor concentration in the extracellular medium by means of cytokine blocked cell receptor expression. Low values of the analyzed indices for CD95 receptor indicated that the cells got free from unnecessary receptor substances in the course of performing its function did not undergo apoptosis. Accumulation of receptors extracellular pool was provided by phagocytosis deficiency. Increase of phagocytosis intensity at a maximum concentration of free receptors was due to the necessity of urgent prevention of unwanted substances accumulation in the blood serum.

The purpose of the study was to reveal age characteristics of the components of postural control in women 55-64 years old. Computer dynamic stabilometrical complex «Smart Equitest Balance Manager» was used for the comprehensive evaluation of the equilibrium function in elderly women. The following tests were used: Sensory Organization Test (SOT), Motor Control Test (MCT), Rhythmic Weight Shift (RWS). On the basis of the analysis of postural control parameters and according to the SOT data, we have found a quality decrease of the equilibrium function in the functional tests 1-4, as well as reduction in the degree of involvement of the somatosensory information in the balance control in women after 59 years. In addition, comparative analysis also revealed a weakening of postural strategy in all six functional tests SOT. However, no age-related changes have been found in the quality of the equilibrium function (functional tests 5 and 6), being the result of SOT assessment, as well as the degree of involvement of visual and vestibular information in the balance control. The analysis of the MCT test has shown deceleration of coordinated motor reactions. RWS test analysis has shown that women from 59 years had a quality deterioration of gravity control center while moving in the frontal and sagittal directions, as well as speed reduction of the gravity center movements in the sagittal direction.

Обоснована процедура экспериментального определения параметров асимптотики концентрации углекислого газа при исследовании динамической сорбционной активности регенеративного патрона изолирующего респиратора на химически связанном кислороде. Показано, что погрешность оценивания доли непоглощенных молекул углекислого газа на основе выборочного контроля в рамках схемы Бернулли уменьшается, если дисперсию оценки в условиях полноты достаточной статистики искать на классе смещенных оценок. Полученные результаты можно использовать для расчета феноменологических констант модели рабочего процесса изолирующего дыхательного аппарата, оптимизации температурного режима его регенеративного патрона и обоснования гарантированного срока защитного действия аппарата.
