METHOD OF SEQUENTIAL CHANGINGOF STATIONARY STATES FOR ONE-DIMENSIONAL FILTRATION PROBLEM WITH LIMITING GRADIENT OF PRESSURE
Authors: Belova O.V. , Shagapov V.Sh.
Published: October 2020

Taking into account nonlinear eﬀects observed in experiments with low-per- meability layers, at low pressure gradients (e.g., about 105 Pa/m), reﬁnement of Darcy law is proposed. On the basis of this model, by means of method of sequential change of stationary states and the problem of one-dimensional ﬁlter- ing is numerically solved. It is established that approximate solutions received by the method of sequential change of stationary states, for the description of distribution of pressure in layer and a well production, will be agreed with the numerical solution of the equation of a ﬁltration in full statement. The analysis of inﬂuence of pressure gradient q and limiting exponent deﬁning the rate of yield of the nonlinear ﬁltration law to the linear Darcy’s law with increasing pressure gradient γ, on the features of hydrodynamic ﬁelds and well production is carried out.

Authors: Nifagin V.A. , Gundina M.A.
Published: October 2020

The boundary value problem with relations to the theory of ﬂow with non- linear hardening in derivatives stress and strain tensors in the parameter loading is formulated to estimate local mechanical properties in the vicinity of crack tip of mode of loading for plane strain of elastic-plastic material at the stage of quasi-static growth. Complete solutions are obtained by the method of asymp- totic decompositions. The redistribution of stress and strain ﬁelds in the plastic region at quasi-static growing crack for the intermediate structure is investigat- ed. The form of plastic zones was found in the evolution of fracture process of material. We also obtained direct estimates of errors and diameters of con- vergence when dropping residues of series.

One generalization of Marchaud inequality onsignsensitive weights
Authors: Ibragimova B.M.
Published: October 2020

At the proof of a classical Marсhaud inequality for equidistant moduli of continuity of the highest degree the reduction of their deﬁnition for arbitrary sign of a step of a ﬁnite diﬀerence to positive values of this step is used. In case of moduli of continuity with a weight such reduction reduces deﬁnitions of moduli of continuity to restriction. Consequently for determination of properties of moduli of continuity with a weight other approach of reasoning is required. Unlike usual weight signsensitive weight allows to consider not only an absolute value of an increment of function, but also a sign of this increment. In the work for metrics with signsensitive weight an analogue of Marchaud inequality on estimation of modulus of continuity of given degree over modulus of continuity of a higher degree is obtained.

ALPHA-MATRIX AND GRAPH-GENERATED GRAMMARS
Authors: Tsvetov V. P.
Published: October 2020

In this paper we consider the extension of graph-generated grammars based on their matrix representations. We study two classes of graph-generated grammars associated with the vertex and edge marking of graphs. We define alpha-matrices over a semiring of languages specified by finite alphabet A and then define the corresponding matrix algebras. These concepts are then used for constructive representation of graph-generated languages and research of their equivalence. We define a matrix-generated grammars as a natural superclass of graph-generated grammars. All the proofs are illustrated by examples.
CASES OF INTEGRABILITY CORRESPONDING TO THE PENDULUM MOTION IN FOUR-DIMENSIONAL SPACE
Authors: Shamolin M. V.
Published: October 2020

In this article, we systemize some results on the study of the equations of motion of dynamically symmetric fixed four-dimensional rigid bodiespendulums located in a nonconservative force fields. The form of these equations is taken from the dynamics of real fixed rigid bodies placed in a homogeneous flow of a medium. In parallel, we study the problem of the motion of a free four-dimensional rigid body also located in a similar force fields. Herewith, this free rigid body is influenced by a nonconservative tracing force; under action of this force, either the magnitude of the velocity of some characteristic point of the body remains constant, which means that the system possesses a nonintegrable servo constraint. We also show the nontrivial topological and mechanical analogies.

Published: October 2020

In the work transition to discrete time in the equation of movement of van der Pol Dyuffing generator is described. The transition purposeto create mappings of the generator as subjects of the theory of nonlinear oscillations (nonlinear dynamics) in discrete time. The method of sampling is based on the useof counting of the pulse characteristic of an oscillatory contour as the sampling series for a signal in aself-oscillating ring active nonlinearity the resonator feedback. The choice of the consecutive scheme of excitement of a contour allows to receive the iterated displays in the form of recurrent formulas. Two equivalent forms of discrete displays of the generator of van der Pol Dyuffingcomplex and valid are presented. In approximation of method of slow-changing amplitudes it is confirmed that the created discrete mappings have dynamic properties of an analog prototype. Also within the numerical experiment it is shown that in case of the high power of generation the effect of changing of frequencies of harmonicas of the generated discrete signal significantly influence dynamics of the self-oscillators. In particular, in the discrete generator of van der Pol Dyuffing the chaotic self-oscillations are observed.

Leading the Way? State Employers’ Engagement with a Disability Employment Policy
Authors: Østerud Kaja Larsen
Published: October 2020

In the literature on labor market integration, there is growing recognition of the importance of employers. This article aims to contribute to this stream of research by investigating state employers’ engagement with a soft employment quota launched alongside a wider initiative in Norway, named the Inclusion Dugnad. An initial document analysis showed that only 3.1% of state employers fulfill the quota at the early stage. Analysis of 10 state employer interviews revealed that they appeared to be mostly passive and, to some degree, dismissive of the Inclusion Dugnad. They relied on passive measures where disabled job seekers are expected to actively seek out the employer and not the other way around. The main obstacles to achieving employer engagement seemed to be the apparent lack of disabled applicants and the reported conflict between the goals of the Inclusion Dugnad and the cost-cutting and productivity standards governing the state employer sector.

Published: October 2020

Inkább beszédben mint írásban, Bori Imre prózapoétikai tanulmányainak olykor még a Tanár Úr legelkötelezettebb diákjai is azt szokták felróni, hogy talán túlzottan nagy hangsúlyt fektetett az elemzett regények, elbeszélések témájának, fabulájának részletes ismertetésé- re, leírására, mai divatos szóval élve úgymond „spoiler”-ként azoknak az érdeklődőknek, akik netán először Bori könyveit olvasnák el, és csak utána vennék kézbe az elemzett regényeket, elbeszéléseket. Azt azonban már kevesebben merik állítani, hogy ez feltétlenül az elméleti felismerések, a pontos irodalomtörténeti besorolások rovására ment volna. Jelen tanulmány egyik célja, hogy felfedje: nem véletlenül van ez így, valamint, hogy ennek oka sem a kritikusok jóindulatában, sem a Tanár Úr előtt való kötelező tisztelgésben keresendő. Tanulmányom egyik alapfelvetése az ún. „Bori Imre-paradoxon”, amely három, egymással látszólag (főleg a mai irodalmár szemével nézve) nehezen összeegyeztethető, Bori Imre módszerét jellemző tulajdonságból áll: rendkívüli elemzői alaposság, részletekbe menő tematikai leírások és olykor bizony bosszantó forrás- és idézetmegjelölés-hiány. És míg a legutóbbival valóban nem lehet mit kezdeni, az első kettő véleményem szerint nemcsak hogy nem zárja ki egymást, hanem egyenesen függ is egymástól, egymásból következik. Ezt az (elő)feltevést két ismert Bori Imre-monográfiából merített példatár alapján próbálom majd bebizonyítani: Bori Krúdy Gyula, illetve Kosztolányi Dezső munkásságának szentelt könyveiből.

Background: Tuberculosis (TB) is an infectious disease which can occur in the lungs and extra lung. One kind of extra lung TB is Cerebellum tuberculoma, which is one of rare manifestations form of TB, difficult to diagnosed, because sign and symptom is not specific.Case: A 17-year-old female presented a TB symptoms. She also had contact with her neighbor that was diagnosed with TB. In physical examination there was reduced motor function on her right extremities. Chest radiology revealed opacities in 2/3 superior in the left lung before treatment. Computed Tomography (CT) head scan with contrast showed ring contrast enhancement in left subcortical hemisphere cerebellum with size as 1.8 x 1.8 x 1.7 cm. Multiple lymphadenopathy in right-left upper-aid jugular and lymph node subcentimeter in right of submandibular, right-left lower jugular with varieties of size, the biggest is 1.6 x 1.5 cm. After 6 months treatment the tuberculoma of cerebellum was gone.  Conclusion:Cerebellum tuberculoma is a rare presentation of active TB. Radiological imaging plays an important role in the diagnosis and monitoring of the disease. The appereance of tuberculoma on our patient CT showed nodular-enhancing lesion. Intracranial tuberculoma should be treated conservatively, since the majority of these lesions resolve completely with Anti-Tuberculosis Drugs (ATD). Our patient started ATD and the lesions completely disappeared within 6 months. We wanted to present our case due to well-responded to ATD and being an example of atypical presentation of tuberculosis both clinically and radiologically.

Published: October 2020

The article presents conjunctural aspects that show the growth of restrictive freedom policies in the framework of a Penal State and the challenges that are presented in the political agenda regarding the necessary adoption of emerging measures to mitigate contagion situations by COVID-19 in the prison system and socio-educational. It presents data on the large percentage of incarceration in Brazil, as well as on the contagious infectious diseases that are evident in the prison population and that reveal the exposure of this population to risks of contagion in pandemic situations. It also exposes data that reveal public administration strategies adopted to mitigate the effects of the recent pandemic on this population, highlighting the particularity of those adopted by different states in the country, such as Amazonas. In its conclusion, it problematizes aspects of the criminal policy developed at the intersections of institutions and agencies such as the police, the courts, the prisons, and agencies managers; highlighting that they operate within the dimensions of race, class, and gender. From these aspects, it emphasizes the importance of registering important intervention proposals that bring mitigating impacts on the daily life of prisons in Brazil.

Biological systems often need to operate in complex environments where conditions can rapidly change. This is possible due to their inherent ability to sense changes and adapt their behavior in response. Here, we detail recent advances in the creation of synthetic genetic parts and circuits whose behaviors can be dynamically tuned through a variety of intra- and extra-cellular signals. We show how this capability lays the foundation for implementing control engineering schemes in living cells and allows for the creation of biological systems that are able to self-adapt, ensuring their functionality is maintained in the face of varying environmental and physiological conditions. We end by discussing some of the broader implications of this technology for the safe deployment of synthetic biology.

To expand the application scope and increase the demand for non-crimp fabrics (NCFs) as a lightweight vehicle material, the delamination and thermal strain in NCF composites must be restricted. Accordingly, to simultaneously improve the interfacial bonding and thermal stability of the NCF composites, in this study the epoxy resin, in which SiO2 nanoparticles was modified by a silane coupling agent, were infused to the stacked NCFs and between the layers of NCFs through the vacuum-assisted resin infusion molding (VARIM) process.

The present research is embedded in the professional development and research line and in the needs of secondary education and first-year university teachers. We focussed on evidencing the importance of teachers’ professional training to include some specific adaptation and skills in intercultural dialogue and understanding -often called Intercultural Competence- because of its direct impact on the sustainable development of human beings, groups, and ecosystems. We investigated the role played by each of the main competencies linked to the following intercultural dimensions: Professional Identity, Ethics and Axiology, Methodology, and Inclusive Education. We used an integrated methodology and a cross-study of data, performed after the obtention of a three-cornered evaluation of results collected in focus groups, interviews, and questionnaires. We were able to show the impact of intercultural dialogue and understanding in the education for a sustainable development pattern. This is fundamental to set up a new ecology of forms, knowledge, attitudes, and educational meanings, further used to update teachers and students’ training in sustainable ecology and cultural diversity. Progress made in these complementary competencies -Professional Identity, Ethics and Axiology, Methodology- were appraised by teachers participating in the present study; the latter showing an increased interest and demand for the intercultural competence, after increasing their proficiency in the other complementary competencies.

Published: October 2020

This study investigates the failure of a roof with steel truss construction of a factory building in Tekirdag in North-western part of Turkey. The failure occurred under hefty weather conditions including thunderbolt, lightning strikes, heavy rain and fierce winds. In order to interpret the reason for the failure, the effects of different combinations of factors on the design and dimensioning of the roof are checked. Therefore, finite element analysis is performed several times under different assumptions and considering different factors aiming to determine the dominant ones that are responsible for the failure. Each loading condition gives out a characteristic form of failure. The scenario with the most similar form of failure to the real collapse is considered as the most likely scenario of failure. Also, the factors included in this scenario are expected to be the responsible factors for the partial collapse of the steel truss structure.

Conclui que a discussão se centra nos pilares da avaliação e da responsabilização revelando o próprio desenho das políticas que acionam a accountability quando desconsideram modelos mais democráticos e sofisticados de prestação de contas.
Pesquisas sobre o ensino da Literatura no período de 2008 a 2018: o que revelam e as lições que ficam
Authors: Nichio Elaine Rodrigues , Pacífico Juracy Machado
Published: October 2020

O artigo é resultado de pesquisa desenvolvida no âmbito da pós-graduação e apresenta o que vem sendo discutido sobre o ensino da literatura no Brasil. O estudo buscou responder à questão: o que evidenciam as referidas pesquisas sobre a temática e quais referenciais são basilares para as análises. Foi desenvolvido por meio de pesquisa do tipo estado do conhecimento em teses e dissertações, publicadas no período de 2008 a 2018, no portal domínio público e em programas de pós-graduação da Universidade Federal de Rondônia (UNIR). Os dados foram levantados a partir dos descritores “literatura” e “ensino de literatura”. Os resultados apontam que há dificuldade para distinguir aula de literatura e aula de língua portuguesa. Notou-se a preocupação em tornar o ensino motivador. Os cursos da UNIR apresentam pesquisas, no âmbito da literatura, mas voltadas à crítica literária. Conclui-se que preponderam as pesquisas no campo teórico da literatura. Bakhtin (1997), Candido (2011), Cosson (2006; 2014) e Freire (1979; 1988; 1997; 2007) foram as principais bases presentes nos estudos que associam teoria e prática.
Successful Managed Pressure Cementing on an Exploratory Well Operation in Ultra-Deep Waters of Mexico

The operation described in this paper is related an ultra-deep-water exploration well drilled in the Mexican waters of the Gulf of Mexico (GOM) and the first drilled by the operator in the area. From the onset of planning, the base case was to integrate a Managed Pressure Drilling (MPD) system into the drilling program to assist with pore pressure uncertainty, pressure ramp increase, and narrow Pore Pressure/Fracture Gradient (PP/FG) window operations including drilling, tripping, running casing and cementing, with the latter being a procedure that was not included in the initial stages of the project but discussed and implemented during the execution phase (Moghazy et al. 2018, Gradishar et al. 2017).

The well is located in a water depth of 3,276 m (10,748 ft). Given the exploratory nature of the well, there was an assumed pressure ramp that would demand an excessive number of casing strings with a conventional approach using an overbalanced Mud Weight (MW). During the drilling phase and taking advantage of the ability to adjust the bottom hole pressure instantaneously, dynamic pore pressure tests were performed to conclude that the pressure ramp was not as aggressive but lead to a narrow window that would not allow conventional cementing of the 13-3/8-in. casing.

Strong planning was required between the operator's engineering and operations teams, cementing services provider, MPD consultant, and MPD service provider team. The uncertainty about the actual size of the hole yielded an even more challenging Managed Pressure Cementing (MPC) engineering analysis (Valecillos and Craigh 2016). This cementing job was a success with no fluid losses, a hazard that had been assigned a high probability.

The specific objective for the MPC application was to set 13-3/8-in. casing to isolate the critical formation and to safely continue drilling further stages of the well with an improved Leak-off Test (LOT) at the shoe.

This job represents the deepest water, and first from a drillship, for a managed pressure cementing job performed by both operator and MPD service provider. Additionally, a critical cementing operation was successfully performed using the Managed Pressure (MP) approach. The well construction objectives using MPD were also achieved while avoiding the use of a contingency liner which saved an additional USD3.5 MM from the planned AFE (Hernandez and Valecillos 2018).
Numerical Modeling, Simulation and Lab Testing of Foam-Assisted Mud Cap Drilling Processes Dealing with Non-Newtonian Foam Rheology
Authors: Wang Yanfang , Thiberville Caitlyn , Kam Seung
Published: October 2020

When drilling challenging formations such as very thick highly fractured sour reservoirs or carbonate/karst formations, a lost-circulation zone can be encountered. This causes mud to be lost and gas kick to take place, making the drilling process uncontrollable. Blocking or plugging wide fractures is impossible in many cases, which results in severe safety issues associated with toxic gases.

This study investigates an application of mud cap drilling by injecting foam mixture into the annulus for well control in such harsh conditions. An annular fluid column with foam mixture can be used to prevent kicks and push the toxic gas back into the formation down along the annulus. This foam-assisted mud cap drilling process has been proved to reduce non-productive time and fluid expenses.

This study presents how to model and simulate the process with accurate foam characteristics when foams are used to suppress gas kicks under certain well and fluid conditions. More specifically, this study deals with three scenarios: Base Scenario with a relatively short response time such that the injected foams do not contact the formation gas, and Scenario 1 and 2 with a relatively long response time such that the injected foams interact with the gas, with and without foam coalescence respectively, at the foam/gas interface. The results show how mud-cap drilling parameters (such as pressure, foam density (or, equivalent mud weight), foam velocity, and foam quality) change at different operating conditions and scenarios. Non-Newtonian foam rheology, depending on bubble size and bubble size distribution as modeled by Wang et al. (2017), lies at the heart of this simulation study.
