The modern food industry offers the consumer bread baked with sourdough using various biologically active components of plant origin. In the production of yeast-free bread, it is advisable to use a sourdough from biologically active strains of Streptococcus thermophilus selected by the Gorsk State Agricultural University. The authors have compiled a starter culture from local strains of lactic acid microorganisms selected by the Research Institute of Biotechnology of the Gorsky State Agrarian University. Research was carried out at the Department of Biological and Chemical Technology of the Gorsky State Agrarian University. We also used cones of wild-growing hops from the botanical garden of the Gorsky State Agrarian University in order that the bitter acids present in the hops suppress the putrefactive microflora, do not have a detrimental effect on local strains of lactic acid microorganisms and allow increasing the productivity of the hop starter culture. Yeast-free bread is easily absorbed by the body, does not harm the intestinal microflora, retains useful properties during storage. The flour used in the experiment met the requirements of GOST 26574–85. When using wild-growing hops in the production of bread, useful substances included in its composition were determined that could increase the quality and safety of bread. The content of alpha acids was 6.0%, and that of essential oils was 0.7%, which corresponds to GOST 32912–2014. We used two strains of a lactic acid microorganism of local selection – Streptococcus thermophilus. Hops were extracted for 30 min at a temperature of 96 °C. Laboratory baking of bread was carried out in accordance with GOST 27669–88. Studies have shown that bread prepared using a local strain of Streptococcus thermophilus selected by the Gorsky State Agricultural University and wild-growing hops is of high quality.

The hydrogen content gradients that occur during hydrogen permeation through palladium-silver membranes produce complementary strain gradients of lattice expansion, which induce opposing Gorsky Effect components of Diffusion Flux. A body of observations of related “uphill effects” and allied diffusion phenomena have recently been studied, using sheet and tube membranes; these phenomena have been correlated with hydrogen pressure-hydrogen content relationships of the Pd77Ag23Hn system.

Au cours des deux dernières décennies, d’énormes progrès ont été réalisés dans la miniaturisation des dispositifs optoélectroniques et des systèmes nanoélectromécaniques à base de capteurs grâce à l'intégration de nanofils quasi unidimensionnels. Le présent travail porte sur l'analyse de la réponse mécanique de nanofils GaAs semi-conducteurs préparés sur un substrat de silicium par épitaxie par jet moléculaire. Le comportement mécanique du nanofil est caractérisé par des essais de flexion in situ dans un MEB et en combinaison avec la diffraction des rayons X. L'objectif de ce travail est d'identifier le mécanisme responsable de la relaxation anélastique qui a été observée après des essais de flexion ou flexion ou de flambage effectués sur des nanofils de GaAs dopés avec du Be. La déformation anélastique est quantifiée en utilisant un algorithme de corrélation d'images numériques. L'accord entre les simulations FEM et les données mesurées montre que la relaxation anélastique peut être attribuée à l’ effet Gorsky dans les nanofils, c’est à dire au couplage entre la diffusion des défauts ponctuels et le gradient de contrainte. Les nanofils de GaAs dopé avec du Be ont été sollicités in situ en flexion latérale trois points en utilisant SFINX et la XRD sur la ligne de lumière P23 à PETRA III. La flexion a été induite dans les nanofils par le mouvement latéral de la pointe du SFINX. Les nanofils présentent une déformation élastique, une déformation plastique et une relaxation anélastique dépendant du temps. La relaxation anélastique donne lieu à un coefficient de diffusion de 2.71 x 10 puissance -13 cm puissance 2 et est en accord avec un effet GorskyDuring the last two decades, tremendous advances have been made in the miniaturization of opto-electronic devices and sensor-based nano-electromechanical systems by the integration of quasi one-dimensional nanowires. The present work focuses on the mechanical response analysis of semiconductor gallium arsenide (GaAs) nanowires grown on silicon substrate via molecular beam epitaxy. The mechanical behavior of the nanowires is characterized via in-situ bending tests in a scanning electron microscope and in combination with x-ray diffraction. The aim of this work is to identify the anelastic strain relaxation of the nanowires which was observed as a direct consequence of cantilever bending tests and buckling tests on free standing Be-doped GaAs nanowires. The anelastic strain is derived by using a digital image correlation algorithm. The agreement between FEM simulations and measured data conclusively relate the anelastic relaxation in the investigated nanowires to the Gorsky effect, i.e. the coupling between point defects diffusion and stress gradient. Be doped GaAs nanowires are further examined in the lateral three-point bending configuration by employing the Scanning Force Microscope for in situ Nanofocused X-ray diffraction (SFINX) and x-ray diffraction at beamline P23 at PETRA III. The bending of the nanowires was induced by the lateral movement of the tip of SFINX . The nanowires demonstrate elastic deformation, plastic deformation, and time-dependent anelastic relaxation. The anelastic relaxation yields a diffusion coefficient of 2.71 x 10 puissance -13 cm puissance 2 and is consistent with a Gorsky effect

Pełny tekst źródłaStreszczenie:
Economic depreciation of the total capital stock of a physical asset is determined by the flow of services used in productive activities and by the size of the capital stock. Previous research studies have attempted to analyze economic depreciation by modeling the flow of services. These studies have often failed to fully specify the model by not including important asset specific explanatory variables, and their models were often estimated with restricted functional forms, which implicitly limited the pattern of economic depreciation. This study, on the other hand, uses a flexible functional form which models price as an exponential quadratic function of age, and thus allows the pattern of economic depreciation to be dervied within the model. The behavior of used asset prices are also estimated as an explicit dynamic process which permits a stronger statistical test of the results. In examining the economic depreciation of combine harvesters, this study utilizes specific explanatory variables to account for the effects of changes in the tax code, shocks in demand, and quality and technology differences across combine harvester models. The major empirical results of this study state that depreciation rates are not constant across different ages of combine harvesters and that depreciation rates and patterns are not stable with respect to changes in tax codes. These results present evidence that if further examination of either economic depreciation or optimal replacement problems are to be solved in an internally consistent manner, a more flexible functional form of the used asset price equation must be utilized such as the flexible funtional form used in this study, and changes in the tax code must be included as a specific explanatory variable.

This article examines the use of analytic continua with spatial scaling and with potentially similar reifying effects to rationalize social meaning rather than just sound or sight in cultural sociology. It considers the use of the figure of spatial scaling as a point of entry to elucidate the basic logic by which many sociologists interpret the relation between what is culturally meaningful and what lies “outside” culture (or our concept of culture). Four case studies that illustrate how cultural practices generate meanings and reference in social life are presented: one relating to the creation of distinct color categories from the spectrum of hues in the rainbow as a paradigm for cultural analysis, and the other three relating to the views of Pierre Bourdieu, Randall Collins, and Philip Gorski. These four exemplars suggest that cultural sociology would benefit from dialogue with skeptical counter-principles for establishing—and questioning—our objects of explanation.

In this series of clinical vignettes, a board-certified psychiatrist and life fellow of the American Psychiatric Association illustrates the effectiveness of dream therapy in treating posttraumatic stress disorder (PTSD). Posttraumatic stress disorder (PTSD) can be disabling and difficult to treat, often leading to depression, suicide, and homicide in extreme cases. In this clinical-based reference, acclaimed psychiatrist and neuroscience researcher, Bruce Dow, provides a step-by-step approach for implementing dream revision therapy—a treatment proven to eliminate nightmares, flashbacks, anxiety, and other debilitating effects of PTSD. Drawing from work with patients in both military and civilian settings, Dow shows how to utilize imagery rehearsal exercises to help mitigate the effects of the illness. The vast majority of the book's 11 chapters focus on clinical case studies of patients who have suffered under the effects of the disease—for example, a hotel employee who witnesses a gory suicide; a female police officer whose career-ending crash in her patrol car brings back traumatic memories from childhood; and Vietnam combat veterans with recurrent posttraumatic nightmares. Each vignette offers details of the dream revision method along with clinical tips for ensuring its success. The final chapter features descriptions of brain mechanisms of PTSD and dream revision.

Horror cinema grants bodies and images a precarious hold on sense and order: from the zombie’s gory disintegration to the vampire’s absent reflection and from the shaky camerawork of ‘found footage’ horror to the spectacle of shattering glass in the Italian giallo. Addressing classic horror movies alongside popular and innovative contemporary works, Visceral Screens shows how they have rendered the human form as a type of ‘image-body’, mediated by optical effects, chromatic shifts, glitches and audiovisual fragmentation. The question of signification is central to this metaphorical exchange, since horror frequently pushes both bodies and media to the limits of their expressive capacity. Conducting their own anatomies of the screen, cutting across bodies and media alike, horror films revel in the breakdown of frames, patterns and figures, exposing the seams between matter and meaning.

Consigned to the deep freeze of critical and commercial reception upon its release in 1982, The Thing has bounced back spectacularly to become one of the most highly regarded productions from the 1980s 'Body Horror' cycle of films, experiencing a wholesale and detailed reappraisal that has secured its place in the pantheon of modern cinematic horror. Thirty years on, and with a recent prequel reigniting interest, this book looks back to the film's antecedents and to the changing nature of its reception and the work that it has influenced. The themes discussed include the significance of The Thing's subversive antipodal environment, the role that the film has played in the corruption of the onscreen monstrous form, the qualities that make it an exemplar of the director's work and the relevance of its legendary visual effects despite the advent of CGI. Topped and tailed by a full plot breakdown and an appreciation of its notoriously downbeat ending, this exploration of the events at US Outpost 31 in the winter of 1982 captures The Thing's sub-zero terror in all its gory glory.

Thomas Mann described the Norwegian author Knut Hamsun (1859-1952) as ‘a descendant of Fyodor Dostoevsky and Friedrich Nietzsche’ in a festschrift compiled for Hamsun’s 70th birthday, featuring articles by Heinrich Mann, Musil, Schoenberg, Hesse, Gorky, Masaryk and Gide. However, Hamsun’s reputation subsequently declined so much that on his eightieth birthday he received tributes only from Goebbels, Alfred Rosenberg and Hitler. Although Hamsun won the Nobel Prize for Literature in 1920, his controversial political views overshadowed his literary reputation, and the influence of Nietzsche on his later work has received more attention than that of Dostoevsky. Examination of his novels and correspondence, however, reveals the considerable importance of Dostoevsky in Hamsun’s literary development. Hamsun felt that contemporary fiction was only concerned with psychology as a serviceable element within a specific plot. He contrasted this with the unpredictability of Dostoevsky’s characters, which he saw as true to his own experience of subsisting through menial jobs, and planned to make the basis of his own writings. Despite visiting Russia and the Caucasus, Hamsun never mastered Russian, and read Dostoevsky only in translations. This essay examines those works available to Norwegian readers in the late nineteenth and early twentieth century, and the evidence in Hamsun’s novels and plays of their impact on his creative life. While overviewing the reception of Russian literature in both Sweden and Norway in the late nineteenth and early twentieth centuries, I focus on three of Hamsun’s novels, Sult (Hunger: 1890), Mysterier (Mysteries; 1892) and Pan (1894), analysing the influence of Dostoevsky on Hamsun’s portrayal of poverty, hunger and their effects on his protagonists’ behaviour, and on his treatment of religious and existential themes. I also note the reciprocal process by which Hamsun’s works were translated into Russian, achieved considerable popularity, and had a strong influence on Gorky.

Complex interactions between fuel structure and fire highly affects the fire spread efficiency and localized behaviour. Heterogeneous arrangement of the fuel coupled with variability in fuel characteristics can strengthen or hinder heat transfer efficiency, preheating of unburned fuel and consecutive ignition. In this study, we leverage recently developed non-intrusive unmanned aerial vehicle-based (UAV) methods to spatially resolved field-scale fire behaviour properties and compare them with the Canopy Height Model (CHM) derived from pre-burn lidar measurements. Rate of spread and flaming residence time are calculated and mapped from high-resolution overhead visible footages acquired during a four-hectare prescribed gorse fire. The proposed method allows for quantification of the influence of fuel structure spatial variation on fire behaviour properties by capturing localized fire front and burning time variations associated with negative (“gapsâ€) and positive (“bumpsâ€) changes in canopy height. These findings are supported by results obtained from a novel fire flow visualization method based upon image velocimetry, described here for the first time. Complex fire flow is synthetised via 2D time-averaged motion streamlines and compared with CHM fuel structure. Results suggest that localized fire behaviour changes may be related to flow channelling effects induced by the presence of gaps, enhancing fire flow contact and overall heat transfer efficiency.

Wildfires have been causing considerable damage worldwide, and improving the ability to predict wildfire behaviour will ensure effective emergency response and keep ecosystems and communities safe. Increasing the understanding of factors affecting vegetation flammability is necessary for improving fire behaviour prediction models. This work investigates the influence of moisture content on the flammability of live and dead needles (0-3mm), twigs (3.1-6mm) and stems (6.1-10mm) of gorse (Ulex europaeus L.). Gorse is a shrub invasive in New Zealand, Chile and Western United States. In these countries, gorse poses a fire risk to nearby communities, as it contains flammable volatile resins, accumulates a substantial amount of elevated dead material, and grows in large masses, all of which promote fire ignition and growth. Gorse flammability was quantified with a bench-scale oxygen consumption calorimeter (cone calorimeter) with a focus on heat release rate. Supporting tests were performed on small sub-samples using simultaneous thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) to assess material-scale pyrolysis dynamics, providing fine scale information on the thermal degradation of each tissue type at the particle level. The experimental methodology included investigation of the maximum moisture content at which each tissue type can ignite at 50 kW/m2, which is a reasonable approximation of the heat flux at the vegetation surface during fire front arrival in a shrub fire. Six moisture content levels from zero to the highest ignitable moisture content were then selected, and samples were placed into a climate chamber to set the moisture content of the samples to the desired level. Three replicates of each tissue type were tested in a cone calorimeter at each moisture content. Flammability was assessed based on the heat release rate, effective heat of combustion, mass loss rate, time to ignition and flaming duration. Additionally, a small sub-sample of fresh live and dead needles, twigs and stems was analysed in the TGA/DSC apparatus. TGA/DSC results showed a different thermal degradation mechanism between dried live and dead fuel, with live tissue being more flammable than dead. However, the pyrolysis dynamics were not substantially affected by particle size, suggesting that the differences in flammability attributes measured in the cone calorimeter are likely driven by physical characteristics such as surface-area-to-volume ratio rather than chemical composition. The results of this work contribute to the understanding of gorse flammability and the effect of moisture content and fuel structure on fire behaviour.

This chapter details Dawn of the Dead’s reception by film critics and audiences. Romero was harshly criticised by many (including Janet Maslin and Pauline Kael) who felt that Dawn of the Dead ‘desensitised’ viewers to violence. A number of early criticisms concentrated on the violence, and the effect this appeared to have on some members of the audience. These criticisms keyed into media effects debates that seemed to preoccupy the media regulators. The film itself came second to a broader discussion of screen violence – or was dismissed altogether because of its violence. The chapter goes on to discuss how controversy over Dawn of the Dead’s violence has receded over the years and critics now tend to focus on the satirical aspects of the film. The gore of Dawn of the Dead has become commonplace to the genre; its shock/controversy factor has been lost, which has led to the film becoming less polarising for critics and audiences. But the violent extremity of Dawn of the Dead has, in the past, been seen by many as problematic, just as its gory excess has contributed to its cult status amongst audiences.

Abstract Originally the Morse theory was developed for real-valued functions defined on compact, differentiable manifolds [Morse 1925], [Milnor 1963]. Unfortunately, this does not lead us further than the multivariable phase margin problem where, typically,[ineq]. In many other structured stability problems, the set of uncertainties D x n is more complicated than a mere compact differentiable manifold. It suffices that the uncertainty manifold has a boundary for the “global” results of the previous chapter to fail, although the “local” results remain valid modulo some revisions. Early generalizations of the Morse theory to include the case of manifolds-with-boundary are due to Morse himself. This effort and other early attempts to extend the Morse theory have, more recently, crystallized around the so-called the Stratified Morse Theory [Goresky and MacPherson 1988]. The stratified Morse theory extends the classical Morse theory to the socalled stratified spaces, that encompass practically all sets of uncertainties encountered in robust stability. The idea of the stratified Morse theory, which comprises the case of an uncertainty manifold with boundary, is to decompose, or “stratify,” the space in a disjoint union of submanifolds, or “strata,” of varying dimensions.

This chapter analyses how William Shakespeare's Macbeth offered Roman Polanski scope for a realisation of the evil inherent in the human conditioning its setting of eleventh-century Scotland and the story of feuding, warlike tribes. It explores Polanski's idea of the underlying desire for power in the human condition that leads to evil in the film Macbeth by making extensive use of blood and gore. It also explains the sight of blood and gory effects that provide an unhealthy stimulus for the gratification of the coarser natures of the audience. The chapter mentions Mario Bava's Black Sunday (1960) and George A. Romero's Night of the Living Dead (1968), which were introduced as a new type of horror that made full use of grisly effects. It reviews critical responses to the presence of violence in horror films that are dismissed as unaesthetic.

Abstract The war years were indelibly etched by the interplay of two seemingly opposite tendencies. There was, on the one hand, the dynamic unleashed by a powerful fantasy of national cross-class unity, coupled with the belief that the war was or would be a levelling influence. And, on the other hand, there were persistent expressions of class antagonism. This combination of desire for singularity and incessant conflict contributed to an unprecedented focus on the deep rents in the social fabric produced by economic inequalities. This chapter will suggest that discourses about the nation as one in which sharp class differences were vanquished through a united war effort fed heightened sensitivity on the part of the British public to issues of economic and social inequality.

Abstract A group of technological procedures known as "carbon capture and storage" involve transferring and injecting carbon dioxide (CO2) that has been captured from industrial waste gases into geological formations. The acronym CCUS, or carbon capture, utilization, and storage, is a key technique for reducing emissions that can be used across the energy system. Meeting the fluctuating need for energy while reducing the harmful effects on the environment are two challenges faced by oil and gas production in floating, production, storage, and offloading (FPSO)units. The most crucial operational parameters to reduce energy demand, boost efficiency, and enhance production are identified in this study through the integration of screening analysis and thermodynamic analysis of oil and gas processing plants. Therefore, the primary objectives of this work are to determine how much the operational parameters of an FPSO with carbon capture, use, and storage (CCUS) contribute to the overall effect. The input parameters for the sensitivity analysis are chosen from some thermodynamic and structural design variables. To accomplish the objectives, four machine learning-based screening analysis algorithms—Linear Regression, Support Vector Machine (SVM), Analysis of Variance (ANOVA) and Gradient Boosting Machine (GBM) are used. The impact of three actual crude oil compositions with different GORs and CO2 contents is evaluated. The optimal operating pressure settings of CCS greatly minimize the energy consumption and exergy destruction of the main and utility plants, according to a combination of thermodynamic and screening evaluations. The findings also showed that while the total oil output is solely affected by the GOR content, the total power consumption, CCS efficiency, and CCS power consumption are all significantly more sensitive to the fluid reservoir's CO2 content than GOR. The impact of design variable interactions is also critical in affecting the separation efficiency and/or compression unit performance for situations with high CO2 or GOR content.

In this 2-part publication, the impact of the main low pressure system parameters of a counter rotating Geared Open Rotor (GOR) on mission fuel burn, certification noise and emissions is presented for a 160 PAX medium haul class aircraft. Due to their high propulsive efficiency, GORs have the potential to significantly reduce fuel consumption and emissions relative to conventional high bypass ratio turbofans. However, this novel engine architecture presents many design and operational challenges both at engine and aircraft level. The assessment of the impact of the main low pressure preliminary design parameters of GORs on mission fuel burn, certification noise and emissions is necessary at preliminary design stages in order to identify optimum design regions. These assessments may also aid the development process when compromises need to be performed as a consequence of design, operational or regulatory constraints. Part I of this two-part publication describes the main low pressure (LP) system design choices for a GOR as well as the preliminary design philosophy and simulation framework developed for the assessments. Part II presents the assessment studies. A fixed reference aircraft and mission were used to evaluate the different GOR engine designs. The results are presented in the form of 1-D or 2-D plots in which one or two design parameters are varied at the same time. The changes in mission fuel burn, certification noise and emissions are expressed as differences relative to a baseline design, due to the fact that preliminary design tools were used for the assessments. The main conclusions of the study are: • Increasing spacing between the propellers (from 0.65 to 1.3m) reduces noise significantly (∼6 EPNdB for each certification point) with a relatively small fuel burn penalty (∼0.3–0.5%) • Relative to unclipped designs, 20% clipped CRPs reduce flyover noise by at least 2.5 EPNdB and approach noise by at least 4.5 EPNdB. The corresponding fuel burn penalty is ∼2%. • Sideline and flyover noise can be reduced by increasing the diameter of the CRP and appropriately controlling CRP rotational speeds. Approach noise can be reduced by either reducing the diameters or the rotational speeds of the propellers. • Regardless of clipping, reducing the rotational speed of the rear propeller relative to the forward propeller reduces noise and, to a certain limit, also mission fuel burn. Further reductions in rotational speed would have an adverse effect on fuel burn. • For given rotational speeds of the propellers, the torque ratio of the gearbox is fixed within ±3%.

Abstract The utilization of hydrocarbon gas in enhanced oil recovery (EOR) processes offers two significant advantages: an increase in the recovery factor and a reduction in net emissions. Through core-scale experimental and numerical investigations, effective diffusion coefficients for single-phase and cross-phase behavior were determined by Fu et al. (2021), enabling their application in larger-scale predictions. [1] The primary objectives of this study are to 1) better understand the impact of upscaling from core-scale to field-scale simulations; 2) verify the effect of diffusion mechanism during huff-n-puff by history matching a model for a single well pilot; and 3) conduct a comprehensive sensitivity analysis and optimization of the recovery factor for huff-n-puff schedule, taking into account fracture spacing and injection-production patterns in both the dead and live oil windows of the Eagle Ford formation. The fluids in place in the Eagle Ford shale show a wide range of GORs, with hydrocarbon maturities ranging from black oil to lean gas condensates, [2] therefore, both live and dead oil regions are investigated in this study. Two compositional models, incorporating dual porosity and dual permeability characteristics, were constructed using the Petrel software. The first model replicated a huff-n-puff field pilot study reported by Orozco et al. (2020) in the Eagle Ford [3] and consisted of one well with the well length of 6,240 ft and 26 hydraulic fracture stages. The second model encompassed a single stage of eleven horizontal wells, designed according to the field blueprint reported by Baldwin et al. (2020). [4] Within this model, six wells were allocated for injection and production during the huff-n-puff cycles, four were used as containment wells, and one functioned as a monitoring well at the center of all eleven wells. The well spacing was set at 1000 ft, with the first stage of each well measuring 220 ft in length, and each well containing 10 hydraulic fractures. These fractures were spaced 20 ft apart (cluster spacing), with a height of 100 ft, and a half-length of 500 ft. Once the pilot well's primary and huff-n-puff oil production rate was history matched, the same reservoir properties, including matrix and natural-fracture porosity, permeability, natural fracture spacing, and relative permeability, were applied to the eleven-well model. Both models employed history-matched effective diffusion coefficients and a tuned equation of state fluid model to fluid samples collected and analyzed for the Eagle Ford formation. [5, 1] Results show that models including the diffusion mechanism had a 2.2% higher oil recovery factor compared to those that did not include diffusion after five cycles of huff-n-puff. The sensitivity analysis on hydraulic fracture spacing showed that smaller fracture spacing creates larger contact surface area between the matrix and fracture, promoting the diffusion mechanism and facilitating higher oil recoveries. The sensitivity analysis also revealed that depletion level on the producer before starting Huff n Puff also had an impact on recovery efficiency. Producing a well on primary production for 6 years and then implementing huff-n-puff yielded the most oil cumulative produced. If the huff-n-puff cycle was delayed to 10 years after initial production, cumulative values were lower than at the 6-year mark due to depletion effects and difficulties in re-pressurizing the formation. The sensitivity analysis on the "puff" production period suggested that longer production times delayed the speed of oil production, but resulted in higher oil production after completing six cycles of huff-n-puff. Further sensitivity analysis on the length of the soaking period suggested that longer soaking times delayed oil production and did not contribute significantly to oil production. These parameters’ effects on cumulative oil production and reservoir pressure were analyzed to determine the optimal approach for field application. Investigations on using different injection gases such as CO2, y-grade, and lean gas for dead oil and live oil systems rank the best injectants for maximizing oil production in the following order: y-grade > CO2 ≈ hydrocarbon gas > lean gas. The findings of this study provide a deeper understanding of upscaling considerations and offer recommendations for huff-n-puff pilot designs in the Eagle Ford formation.
