Authors: Shrestha Brijesh , Regmi Manisha , Adhikari Prabesh
Published: November 2021

Actinomyces are a part of the normal flora of the cervicofacial region, gastrointestinal tract, and urogenital tract, but can cause infections when the normal mucosal barrier is lost. Herein, we report a rare case of actinomycosis of the gallbladder in a 60-years-old-female. The patient presented with right hypochondrium pain since three months; ultrasonography showed cholelithiasis with thick oedematous wall. An open cholecystectomy was carried out. Histological examination revealed an inflamed gallbladder with colonies of radiating filamentous structures having numerous sulphur granules which on gram staining showed filamentous gram-positive rods. The diagnosis of Actinomycosis of gallbladder was made. After cholecystectomy, prolonged antimicrobial therapy is recommended for patient with actinomycosis to prevent recurrence and even mortality.

The Normativity of Measure in Gregory Nazianzus’ and Gregory of Nyssa’s Orations on Love for the Destitute Poor
Authors: Tobon Monica
Published: November 2021

Gregory Nazianzus and Gregory of Nyssa between them composed three orations on love of the destitute poor: Nazianzen's Oration 14, Peri philoptōchias and Nyssen's On love of the poor 1 and 2 (De beneficentia and In illud: quatenus uni ex his fecistis mihi fecistis). All three situate leprosy as the most extreme, and therefore paradigmatic, form of poverty as a basis for exhorting Christians to the practice of love. Those suffering from leprosy were stigmatised and excluded from society even by Christians, yet the Gregories exhort them to serve Christ by serving them, supporting pastoral entreaty with theological argument. This paper aims to introduce these orations to those unfamiliar with them and contribute new insights to those who already know them. After situating them in their historical context I summarise each then comment on their content, highlighting Nazianzen's reconfiguration of classical motifs in the service of a revisionist social policy and Christian anthropology rooted in the imago Dei and Nyssen's recourse to ascetic theory with marked similarities to that of Egyptian desert asceticism as taught by Evagrius. This paper's discussion of these prophetic orations will contribute to knowledge of them and by extension of the two Gregories.
Kościół wobec chorych fizycznie i duchowo w świetle wybranych wschodnich tekstów prawnych IV wieku
Authors: Szczur Piotr
Published: November 2021

W niniejszym artykule opisano stanowisko Kościoła wobec chorych fizycznie i duchowo. W rozważaniach oparto się na analizie wschodnich tekstów prawnych IV w., takich jak: Euchologion Serapiona, Kanony Hipolita, Kanony Atanazego, Konstytucje Apostolskie, Kanony Ojców Greckich autorstwa biskupów żyjących w IV w., oraz ustawy synodów, które odbyły się w IV w. na Wschodzie. Z przeprowadzonych analiz wynika, że posługa Kościoła wobec chorych miała znaczenie priorytetowe i była dobrze zorganizowana. Realizowana była przede wszystkim w dwóch wymiarach: materialnym (udzielanie jałmużny, zapewnienie leków oraz miejsc w przytułkach) i duchowym (modlitwa lokalnego Kościoła, a zwłaszcza biskupa, odwiedziny przez biskupa i innych duchownych oraz wdowy, wiernych i katechumenów). Chorzy na specjalnych warunkach korzystali z sakramentów (zwłaszcza z pokuty, która w przypadku choroby penitenta mogła być skrócona). Objęci byli też dyspensami dotyczącymi obowiązkowych praktyk modlitwy i postu, jednak nie byli dyspensowani z udzielania jałmużny. Natomiast chorych duchowo, czyli grzeszników i heretyków, Kościół otaczał opieką duszpasterską. Otrzymywali oni duchowe lekarstwa w postaci karcenia i upominania. Gdyby jednak nadal trwali w grzechach lub w herezji, to dla dobra Kościoła, byli usuwani, aby nie zagrażali zdrowiu duchowemu pozostałych członków wspólnoty.
Znaczenie terminu mandatum w koncepcji historii zbawienia Filastriusza z Brescii
Authors: Szram Mariusz
Published: November 2021

Filastriusz, biskup Brescii (zm. ok. 387 r.), przedstawił w swoim traktacie Diversarum hereseon liber koncepcję historii zbawienia w trzech etapach: sub mandato, sub lege i sub gratia. Autor artykułu wydobywa z tekstu traktatu Filastriusza różne odcienie znaczeniowe terminu mandatum, stosując metody historyczno-porównawczą i filologiczną. Po pierwsze, termin ten oznacza pierwotne przykazanie dane przez Boga człowiekowi w raju (por. Rdz 2, 16-17). Było ono wystarczające do rozpoznania jedynego Stwórcy i oddawania Mu należnej czci. Zostało jednak naruszone przez grzech pierwszych rodziców, a Prawo Mojżeszowe (lex) stanowiło jego przypomnienie. Po drugie, znaczenie terminu mandatum zbliża się do pojęcia prawa naturalnego, mimo że Filastriusz nigdzie go tak nie definuje. Zwraca natomiast uwagę, że na podstawie naturalnej zdolności, otrzymanej w akcie stwórczym od Boga, człowiek mógł przyjąć pierwsze przykazanie. Po trzecie, Filastriusz użył terminu mandatum także na określenie przykazania miłości, przyniesionego przez Chrystusa (gratia Christi). To ono stanowiło istotę przykazania danego ludziom na początku. Tak więc – w rozumieniu Filastriusza i na tym polega oryginalność jego koncepcji – pierwotne przykazanie, określone terminem mandatum, nabiera charakteru swoistej klamry spinającej całe dzieje ludzkości: jest zarówno punktem wyjścia, ustanowionym przez Boga, jak i punktem dojścia, będącym dopełnieniem tego, co zostało udzielone człowiekowi na początku, a potem przez niego częściowo utracone.

Published: November 2021

The cutting relationship and development degree of structural plane control the instability mode and scale of rock slope. The trajectory of rock mass after instability is an important basis for the design of dangerous rock prevention. The back slope of a residential area was investigated in this paper. Based on the survey data of the field structure surfaces, the possible instability mode of the slope rock mass was analyzed by using the stereographic projection method. The shear strength parameters of the rock mass were inverted through the investigation of dangerous rock mass. Finally, ANSYS/LS-DYNA was used to simulate the dangerous rock mass motion trajectory. This study provides a reference for the analysis of the instability process of single rock.
Numerical Simulation Analysis of Hydrothermal Change of Subgrade by Seepage Drainage Geogrid Under the Effect of Asphalt Mixture Freeze-Thaw Action
Authors: Wang Fang
Published: November 2021

In seasonal frozen soil area, the engineering problems caused by the excessive moisture content of the subgrade soil are widespread. In view of this phenomenon, author proposes to employ a new type of research and development of the seepage drainage geogrid (SDG) to cool and drain the soil. Through indoor model test, after two freeze-thaw cycles, the experimental comparison of the size and laying method of various SDG was carried out. The test result shows that the model with a natural grit layer has the most drainage effect. While, the model contains two layers of interconnected grilles has the best cooling effect. The indoor model test is simulated by accurate numerical simulation. The simulation results are compared with the indoor test results. The fitting results of the two results are very high, which provides theoretical support and data guarantee for the application of seepage drainage grille to strengthen the roadbed in the cold road.

Published: November 2021

The wet slime tailing pond formed during the production of accumulated bauxite is a source of artificial debris flow hazard with high potential energy. In order to explore the effectiveness of solidification technology in processing bauxite slime, experimental study was conducted on the strength characteristics of cement-solidified slime with bauxite slime as the test object, so as to investigate the impact of cement contents and curing ages on the compressive strength of cement-solidified slime. According to the test results, the strength and deformation characteristics of solidified slime are related to the cement content, and the higher the cement admixed amount, the greater the compressive strength of solidified slime; the cement-solidified slime samples are subject to brittle failure, and with the increase of strain, the stress first rises to its peak and then decreases rapidly. The findings may serve as reference in processing bauxite slime.
Hydro-Mechanics Analysis on the Strength Development of Cement-Stabilized Sand
Authors: Wang Fangtong , Li Dianqing , Liu Yong
Published: November 2021

Deep cement mixing is an effective ground stabilization technique to control the ground movement on sand areas, and most of the projects have the problem of seepage. The cement slurry is in a fluid state before the initial setting time, the seepage may affect the diffusion process of cement slurry during this period. A hydro-mechanical approach is proposed to investigate the interaction between the seepage and the strength of cement-stabilized sand. The diffusion of the cement slurry under seepage is considered in this study and the diffusion process is simulated by the finite element method. According to the cement concentration at the end of the diffusion process, the strength of cement-stabilized sand can be predicted by combining an empirical formula. Simulation results examine that the existence of seepage and cracks can enhance the non-uniform diffusion process of cement slurry, and the actual strength distribution of the deep cement-mixed sand is far from the ideal state. This indicates that the influence of seepage on the strength of cement-stabilized sand should be considered in the design of projects.

Published: November 2021

A preliminary dynamic test of a two-span continuous girder bridge is reported in this paper, including the design specifications, the numerical model, and the modal identification result. This laboratory bridge is made of aluminum plates and connected via bolts. The finite element method is applied to build a numerical model of the bridge to aid the design and test plan. Several ambient vibration tests are conducted to extract the modal parameters, e.g., modal frequencies, damping ratios, and mode shapes, of the constructed bridge, and the Bayesian FFT algorithm is used for modal identification. We compare the identified results with those predicted by the finite element model and vary the magnitude of load to investigate its potential influence on the modal parameters. Damage cases by loosening structure members are also considered, and significant changes are observed in modal frequencies. The constructed model will be used as a benchmark for damage identification, model updating, and condition assessment, etc.

Published: November 2021

Whether it can quickly and effectively predict the susceptibility of regional earthquake landslides to achieve rapid rescue, loss assessment and post-disaster reconstruction has always been a difficult problem. However, the traditional high-precision evaluation of seismic landslide susceptibility often relies heavily on the complete or incomplete landslide inventory, which is poor in timeliness and cannot effectively evaluate the target area before or shortly after the earthquake. In most cases, the Newmark model relies on experts’ experience to select model parameters, therefore the evaluation result of this method is unstable and it lacks strong generalization ability. A fused model is proposed to classify the positive and negative training samples of the study area through the evaluation results of the Newmark model under the slope units, and it applies a variety of statistical learning models to evaluate the landslide susceptibility of the Wenchuan earthquake based on the classification results of the Newmark model. The results show that the evaluation of the statistical learning model fused with the Newmark model has higher accuracy. This method can overcome the inherent shortcomings of a single Newmark model to obtain better evaluation results without relying on obtaining the complete landslide inventory. Meanwhile, the model can be applied to quickly obtain the evaluation results of regional landslide susceptibility before or shortly after the earthquake, thereby effectively reducing human and economic losses caused by earthquake landslides.

Published: November 2021

The PSHA map must be tested, since hypothesis testing is the heart of a scientific method, and it is inappropriate to adopt the map as the basis of seismic fortification in whole country without any test. Two paths of testing are suggested in this paper. The test result by counting up positive intensity difference shows that up to 2015 the percentages of total underestimation areas on 1990 and 2001 maps of China are equivalences of 5.6% and 6.0% in 50 years, both less than the exceeding probability 10% adopted in the map compiling procedure. The result of a case study of the common buildings with brick-concrete structure and frame structure in Sichuan region by evaluating the benefit of seismic fortification according to the two maps shows that the PSHA maps contribute benefits as economic loss reduction 67.9 and 79.7 billion RMB, death reduction 19439 and 17504 persons, and serious injury reduction 42632 and 37700 persons respectively during 2008 great Wenchuan Earthquake.

Authors: Liu Hongliang , Wei Xinjiang , Zhang Lisha , Xia Chang
Published: November 2021

In water-rich strata, the distribution of groundwater is complicated. Construction projects related to foundation pit engineering in such areas are prone to cause piping failure, fluid soil failure, and other seepage-related failures. Seepage erosion is a kind of seepage failure that occurs inside the soil. Because the process is difficult to observe and measure, seepage erosion is rarely considered in the current foundation pit engineering. This article analyzes the relevant research on seepage erosion, and further clarifies the influence of seepage erosion on soil characteristics. In addition, this article puts forward some suggestions for the shortcomings of the current research on erosion, and made some prospects for future research on erosion in foundation pit engineering, hoping to provide theoretical guidance and thinking inspiration for future research.

Published: November 2021

According to the aims of the runoff protection in coal mining area, taking Jinjie coal mine as an example, the risk zonation and mechanism of runoff leakage were carried out based on the dimen-sionless multi-factor information fusion technique. Based on the analysis of field exploration and borehole data, four key factors affecting the runoff leakage from the roof were identified, which included the deposition features of aquifer in Sala Wusu Group, the distribution of overburden rock and soil mass, effective thickness of aquiclude layer and the height of water flow cracking zone. The evaluation criterion was whether the development height of the water flow cracking zone reaches or exceeds the bottom plate of the sandy phreatic aquifer and even penetrates the surface ground, which results in the complete or partial leakage of the phreatic water. According the evaluation criterion, the influence of coal mining disturbance on runoff leakage was divided into three zones: zone of seriously runoff leakage, zone of general runoff leakage and zone of slight runoff leakage. Furthermore, the influence mechanism of different zones in coal mining also been discussed preliminarily, which included drainage Sarawusu aquifer, groundwater leakage in Sarawusu aquifer, water level fluctuation in Sarawusu aquifer and so on. Finally, classification pattern diagram was drawn.

Published: November 2021

Fluctuating pressure is the main cause of the floor fatigue of the stilling basin with a negative step. Despite investigations of stilling basin with a negative step conducted by many researchers, there is not enough information about the influence of the geometric parameters on fluctuating pressure on the floor. In the present study, fluctuating pressure on the floor of the stilling basin with a negative step was systematically investigated by a total of 85 model tests. The results show that the fluctuating pressure coefficient Cp’ has a process of rapid increase and decrease, and then decreases slowly until it becomes stable, and the maximum fluctuating pressure coefficient Cp’max lies in the reattachment zone rather than in the jet impingement area for Type II-jump. The dominant frequency of the fluctuating pressure on the floor shows a decreasing trend along stilling basin. With the increase of the step height, the Cp’max presents decreasing trend but X*0 where the Cp’max occurs increasing trend. While there has on obvious regularity between incident angle and Cp’. Finally, according to the fitting of test data, an empirical formula to calculate Cp’max is developed. These research results provide reference for the design of stilling basin with a negative step in engineering applications.

Impact of Different Vegetation Zones on the Velocity and Discharge of Open-Channel Flow
Authors: Tang Xiaonan , Guan Yutong , Hu Yuxiang
Published: November 2021

Different types of vegetation widely exist in rivers and wetlands. The vegetation will affect the ecological environment and flow process, thus becoming increasingly significant in river engineering and aquatic environmental management. Previous research on vegetated flow is mainly to understand the flow structure of open channels with fully covered one-layer vegetation. However, vegetation often grows along a river bank and co-exists in different heights. The present paper presents experimental results about the flow characteristics of an open-channel with two sides covered by differently layered vegetation, focusing on the effect of vegetation on the velocity distribution and discharge. Two heights of dowels in 10 cm and 20 cm were used to simulate rigid vegetation and arranged in a linear form on both sides of a channel bed under emergent and fully submerged flow conditions. The velocity at different positions was obtained using ADV (Acoustic Doppler Velocimetry). Measured results demonstrate that there exists a shear layer between free-flow and vegetated zones, indicating that the flow transition occurs between fast-moving flow in the free zone and slowly obstructed flow in the vegetated zone and induces a high shear layer and transverse coherent vortices near the interface. Furthermore, compared with the emergent condition, the discharge through the free-flow region slightly decreases under full submerged conditions while the discharge in the vegetated region increases, indicating that the vegetation does not significantly change the discharge percentage in the free region. These findings on differently-layered vegetation would help riparian management practices to maintain healthy ecological and habitat zones.

Published: November 2021

As the gate pier bracket of an arch dam are of complex structure which is characterized by use of high-grade concrete and more cement, higher adiabatic temperature rise, it is rather difficult to control temperature and vulnerable for cracking, and the cracks would absolutely affect the integrity, endurance and safety of pier gate bracket. It is necessary to take reasonable temperature control measures to reduce temperature stress during the construction and prevent cracking. This paper takes the gate pier bracket at the middle-hole dam section to perform simulation analysis of temperature field and stress field under different temperature control measures by 3D FEM. It proves that such measures as densifying water pipes, improving Phase I target cooling temperature appropriately, reducing Phase I cooling temperature falling variation and keeping insulation in low-temperature season can help reduce temperature stress and prevent cracking with good results.

Published: November 2021

The temporal and spatial accuracy of precipitation of ensemble numerical forecast systems is an important factor that affects the level of meteorological and hydrological coupled forecasting. This article focuses on the current research of verification of precipitation accuracy and statistical post-processing. The verification of forecast precipitation accuracy mainly focuses on the probabilistic characteristics such deterministic accuracy, the resolution, the forecasting skills and the degree of dispersion. Some mainstream statistical post-processing methods have strong performance of spatial downscaling and error correction, but they commonly have the defect of destroying the temporal and spatial dependent structure of precipitation. A comprehensive statistical post-processing method integrated the three functions is the development direction in the future. At the same time, statistical post-processing methods to improve the certainty and probabilistic accuracy of forecast precipitation need to be systematically identified. Its impact on the spatio-temporal dependence structure also needs to be improved.

Masonry arch aqueducts, as important hydraulic structures, constitute an meaningful part of old irrigation infrastructures in China. The constituent materials deteriorate over time, caused by weathering processes and the defect development, influences the mechanical performance of these structures. The paper presents a comprehensive approach to evaluate the structural safety of an old masonry aqueduct with uncertain mechanical parameters and unknown geometric dimensions. This approach employed the 3D terrestrial laser scanning (TLS) to measure the geometric dimensions, and the discrete element analysis (DEM) to analyze the current operational behaviour state of the masonry aqueduct. As a case study, the Zhaimen masonry arch aqueduct in the famous Red Flag Canal, operating for more than 50 years, was investigated in this study. Obvious defects, such as the continuous loss and falling of mortar and the arch ring detaching, appeared in this old aqueduct. The TLS measurement information was used to construct a DEM model. Then this numerical model was applied to analyze the current performance of the exiting masonry arch aqueduct. The results show that the upper structure and the supporting structure can still be stable assuming that the mortar with no bond strength. In other words, the deterioration of the mortar, due to natural weathering and Calcium ion dissolution caused by natural environment and leakage, would not have a fatal impact on the structural safety. The proposed structural diagnosis and performance assessment approach can provide a reference to safety evaluation for similar masonry arch aqueducts.

For environment-friendly dyeing, electrochemical dyeing method was researched. The low consumption of additives during dyeing is beneficial to environmental protection,and the electric field of electrochemical dyeing reduces the salt. Moreover, the K/S value of the fabric increases significantly at the same dye concentration. The alkaline electrolyte in the electrolytic cell may enhance the self-corrosion of the electrode during the electrochemical dyeing process. The results show that the electrochemical dyeing can reduce the amount of additives during the dyeing process.

In this paper, Computational Fluid Dynamics (CFD) and Flow Model Test are applied to study the flow field of 200MW coal fired power plant, then the optimization program is proposed. Firstly, this paper summarizes some essential design points for SCR reactor system with different structures and different characteristic. Then, the initial flow field of the SCR reactor was simulated to find the defect by the Fluent. Then, optimize the flow fields of velocity of SCR system by adding splitters. In order to improve the mixing degree of flue gas and ammonia, Ammonia Injector Grids (AIG) was designed on the basis of the structure of SCR reactor. Considering the pressure loss and installation space were within allowed limits, a new static mixer was designed to optimize the flow fields of concentration. Through the shift of size, angle and altitude of the static mixer, this paper got a best design project. The research results can provide theoretical support and engineering guidance for the transformation and optimization of the new SCR denitration engineering reaction system.

Published: November 2021

Today, in the digital era, all walks of life have diversified development under the penetration of information technology, and the traditional construction industry is inevitably combined with information technology to move toward the direction of intelligent construction. As a broad concept, intelligent construction includes many theories and multiple directions of research, from design to construction to post-maintenance, while flexible construction focuses on the organization of production mode. In this paper, through the comparative analysis of intelligent construction and flexible construction, the framework of intelligent construction and flexible construction is established to deepen the understanding of the two modes, so as to correctly control the direction of intelligent development, and provide a basis for the construction mode of the intelligent era.
Dreaming of Colonialism: Imagining “Place” in Richard Brome’s The Antipodes
Authors: Hetu Matthew Ryan
Published: November 2021

This article explores the colonial mindset behind the depiction of space and travel in Richard Brome’s The Antipodes. Using Benedict Anderson’s Imagined Communities and Robert T. Tally Jr.’s “On Literary Cartography: Narrative as a Spatially Symbolic Act” as frames for reading travel and travel literature in the text offers new insight into reading Antipodes’ underlying colonial mindset that is intertwined with the complex metatheatrical elements of the play. I read Peregrine as a British explorer going into the exotic to reform and impose his own ways of knowing on the people of the Antipodes. However, the complex metatheatrical elements further complicate this colonial reading of the text. The text uses metatheatrical elements that ultimately makes the audience aware of their own role in the space of the play—invoking a sense of self reflection. By focusing on the ways in which the exotic world is constructed and imagined, the nation as a performance, and the colonial discourse and power dynamics underlying the text I argue that The Antipodes can be read through modern literary theory to better understand and display the emerging difficulties and problems that accompany the developing sense of English nationalism and proto-colonialism. In doing so, the text displays the inherent colonial structures that inform and limit the role of both travel literature and the romance genre in “imaging” nations—something that is pivotal to both questioning and understanding the role of the nation in an increasingly global context.

Regional Specificity of the Personality of the Bribe-Giver: the Experience of Sociological Analysis
Authors: Agishev R. R. , Barinova O. N. , Manaeva I. V.
Published: November 2021

Introduction. A sociological analysis of the personality of the bribe-giver is given based on the study of data on the Republic of Mordovia. The relevance of the issue is determined by the following factors: the strengthening of the negative impact of corruption on all aspects of society and the state; the social mimicry of corruption, the stability of ideas in society about the ambivalence of corruption. The purpose of the article is to highlight the regional specifics of the identity of the bribe-giver.

Methodology and sources. The neoclassical paradigm of the study of corruption links corruption phenomena with the decomposition of the state apparatus and the erosion of the moral foundations of society. In this vein, the authors explore the dual nature of corruption, that is, its conditionality by both the government and society. In the context of Durkheim's anomie theory, the motivational complex of bribe-takers is analyzed.

Results and discussion. The objectives of the study required a mass survey (n = 400, ∆ ±5%), which represented the composition of the population of the region by gender, age, type of activity and type of locality. Within the framework of the study, a qualitative and quantitative description of the corrupt behavior of the bribe-giver was carried out, his motivational complex was revealed, and his subjective assessment of the dynamics of corruption and the effectiveness of anti-corruption policy was revealed. The following regional features of the personality of the bribe-giver are revealed: the age of the highest economic and social lability, the average level of corruption activity, the low size of the average amount of a bribe, acting as the initiator of a corrupt bribe, the perception of a bribe as a rational means of solving problems, pronounced negativism in assessing the authorities.

Conclusion. Participation in corrupt transactions imposes a more or less pronounced imprint on the personality of the bribe-giver, which consists in the deformation of the practices of relations with representatives of state bodies, the gradual loss of immunity to criminal or semi-criminal activities, the partial degradation of socially significant moral values, the transformation of corrupt practices from a social anomie to a social norm.
