Placing automobility in postcolonial cities: Towards an ontology of a displaced past

The mobility turn offers a rich terrain for research to investigate the exercise of politics and power in movement through attention to associated meanings and practices. Despite this, the ontologies that can anchor this research within a historical imagination remains largely uncharted. Happily for us, coming from the opposite direction history, and especially the field of transport history, has grappled with mobilizing history in the face of the mobility turn. Several scholars have offered “usable past” as a mode of mobilizing mobility cultures of the past to inform policy actors about future choices. But is the ontology of a usable past appropriate for countries enmeshed within pre/post/colonial histories of displacement in their society and culture? Employing a case of automobilization in the city of Bengaluru in India, this paper sketches an exposition of the “displaced past” in sedimented residues that continues to live and contest the enterprise of automobility.

The Application of Salutogenesis in Politics and Public Policy-Making

In this chapter, the authors thoroughly discuss the different possibilities of applying salutogenesis in politics and public policy. Politics is one of the upstream conditions that shape our individual lives as well as our society. Thus, asking about if and how salutogenesis can be applied to this field appears to be a most significant subject in Part IV of the Handbook relating to salutogenesis beyond health. In all of his writing about his model, Aaron Antonovsky emphasised how politics and policies contribute to shaping individual and collective abilities to strengthen salutogenic resources. The authors of this chapter approach this issue from the opposite direction, asking, ‘how can salutogenesis contribute to outlining strategies and structural processes linked to politics and policymaking?’ Their creative discussion succeeds in bringing the reader the utility of the salutogenic approach in addressing such issues.

Profundidade: uma dimensão vivida pelo corpo

Este artigo discute a profundidade numa direção oposta à sua objetividade. Não se trata de discorrê-la como uma habituada coordenada do espaço ou como um parâmetro referente à extensão espacial. Desdobra-se aqui a profundidade num nível subjetivo: como uma dimensão vivida pelo corpo. À luz da fenomenologia do filósofo Maurice Merleau-Ponty (1908–1961) e de sua análise dos planos pictóricos do artista Paul Cézanne (1938–1906), enunciam-se algumas considerações sobre a existência da profundidade como uma dimensão que estrutura a relação CORPO-ESPAÇO. A profundidade subjetiva se torna potencialidade para a disciplina da arquitetura ao ser responsável pelo engajamento corpóreo. Palavras-chave: Profundidade; Fenomenologia; Merleau-Ponty; Cézanne; Relação CORPO-ESPAÇO. Abstract This article discusses depth in an opposite direction to its objectivity. It is not a matter of discussing it as a familiar coordinate of space or as a parameter referring to spatial extension. In this article, depth is unfolded on a subjective level: as a dimension lived by the body. Based on the phenomenology of the French philosopher Maurice Merleau-Ponty (1908–1961) and on his analysis of the pictorial planes of Paul Cézanne (1938–1906), some considerations are made about the existence of depth as a dimension that structures the body in the space. Subjective depth becomes a potentiality for the discipline of architecture by attributing plasticity to the BODY-SPACE relationship and by being responsible for corporeal engagement. Keywords: Depth; Phenomenology; Merleau-Ponty; Cézanne; BODY-SPACE relationship

Definitional Skills as a Bridge towards School Achievement

The general aim of the current study was to investigate the role of definitional skills in promoting primary school achievement (third- to fifth graders) and how school learning may shape definitional skills. Marks from four school subjects, linguistic (Italian and English) and scientific (Math and Science) were collected as well as scores in a Definitional Task. These two domains were chosen as they clearly entail the two different definition types, that is, lexicographic and scientific. Results indicated that scientific school subject marks are more predictive of definitional skills than linguistic school marks are. The opposite direction (i.e., how definitional skills are predictive of school achievement) appears less clear. In sum, the results, although preliminary, suggest that definitional skills represent a bridge towards school achievement as they promote good marks in all disciplines. Moreover, definitional skills are predicted from levels of competence acquired especially in scientific school subjects that request a higher degree of formal/organized learning. It is then of primary importance to promote interaction–integration between these two kinds of concepts via formal schooling.

Efficiency of the Wireless Power Transfer System with Planar Coils in the Periodic and Aperiodic Systems

This article presents the results of the proposed numerical and analytical analysis of the Wireless Power Transfer System (WPT). The system consists of a transmitting surface and a receiving surface, where each of them is composed of planar spiral coils. Two WPT systems were analysed (periodic and aperiodic) considering two types of coils (circular and square). In the aperiodic system, the adjacent coils were wound in the opposite direction. The influence of the type of coils, the winding direction, the number of turns, and the distance between the coils on the efficiency of the WPT system was compared. In periodic models, higher efficiency was obtained with circular rather than square coils. The results obtained with both proposed methods were consistent, which confirmed the correctness of the adopted assumptions. In aperiodic models, for a smaller radius of the coil, the efficiency of the system was higher in the square coil models than in the circular coil models. On the other hand, with a larger radius of the coil, the efficiency of the system was comparable regardless of the coil type. When comparing both systems (periodic and aperiodic), for both circular and square coils, aperiodic models show higher efficiency values (the difference is even 57%). The proposed system can be used for simultaneous charging of many sensors (located in, e.g., walls, floors).

Temporal loudness weights: Primacy effects, loudness dominance and their interaction

Loudness judgments of sounds varying in level across time show a non-uniform temporal weighting, with increased weights assigned to the beginning of the sound (primacy effect). In addition, higher weights are observed for temporal components that are higher in level than the remaining components (loudness dominance). In three experiments, sounds consisting of 100- or 475-ms Gaussian wideband noise segments with random level variations were presented and either none, the first, or a central temporal segment was amplified or attenuated. In Experiment 1, the sounds consisted of four 100-ms segments that were separated by 500-ms gaps. Previous experiments did not show a primacy effect in such a condition. In Experiment 2, four- or ten-100-ms-segment sounds without gaps between the segments were presented to examine the interaction between the primacy effect and level dominance. As expected, for the sounds with segments separated by gaps, no primacy effect was observed, but weights on amplified segments were increased and weights on attenuated segments were decreased. For the sounds with contiguous segments, a primacy effect as well as effects of relative level (similar to those in Experiment 1) were found. For attenuation, the data indicated no substantial interaction between the primacy effect and loudness dominance, whereas for amplification an interaction was present. In Experiment 3, sounds consisting of either four contiguous 100-ms or 475-ms segments, or four 100-ms segments separated by 500-ms gaps were presented. Effects of relative level were more pronounced for the contiguous sounds. Across all three experiments, the effects of relative level were more pronounced for attenuation. In addition, the effects of relative level showed a dependence on the position of the change in level, with opposite direction for attenuation compared to amplification. Some of the results are in accordance with explanations based on masking effects on auditory intensity resolution.

ATTEMPT TO IMPROVE THE OPERATING AND TECHNOLOGICAL PROPERTIES OF THE COMBINED GRAIN WASHING MACHINE

Washing machines are used in the production lines of grain cleaning departments of flour mills for thorough cleaning of the grain surface, in particular, its grooves from the remnants of organic and mineral dust, microorganisms and mold. In addition, the grain mass during washing is cleaned of hydrodynamically light and heavy impurities - chaff, seeds of waste plants, straw fragments, mineral particles in the form of sand, small stones, lumps of earth, as well as spores and wormwood seeds. At the same time, foreign odors of grain disappear.Experience in the operation of Ж9-БМА machines shows that along with many advantages, they have some disadvantages. In particular, the productivity of the machine 10 t / h does not correspond to the productivity of the conjugated technological equipment of the production line, and the specific water consumption for washing grain is 1.8… 2.0 l / kg, which is too much in modern conditions of acute shortage of drinking water. Enterprises to abandon the use of washing machines. In addition, certain problems and inconveniences are caused by the design of the sieve shell of the impression column. Stamped sieves with scaly asymmetric holes have a low coefficient of living cross section, which complicates the process of dehydration of washed grain, quickly corrode and rub, require special attention during installation or replacement. Therefore, an attempt is made to eliminate these shortcomings.In particular, the reduction of water consumption is achieved due to the elimination of the grain hydraulic conveyor during its transfer from the washing bath to the pressure column. For this purpose, a device for mechanical overloading of grain by a rotary bucket device located within the alloy chamber is used. At the same time, attention was paid to the separation of light organic impurities from the grain. This decision needs further explanation.The functional diagram shows that the initial grain mixture enters the receiving device, which feeds it with a minimum vertical speed into the ascending water streams created by the screws of two grain augers rotating with the same frequency in the opposite direction. The augers pick up the grain and, keeping it afloat in a suspended state, mix it with the water of the washing bath. At the same time the grain is washed and particles are separated from it, which differ from it in terms of density: mineral impurities begin to sink, fall down and through the longitudinal slit in the auger trough fall into the area of the auger for mineral impurities. This auger transports the "stones" in the opposite direction to the funnel with the ejector of the hydrotransporter of mineral particles. Light impurities, during the transportation of grain by grain augers, float to the surface of the water, the level of which in the washing bath is maintained up to the axis of the augers. Together with grain and water, these impurities are pushed out of the bath into the alloy chamber.In the chamber, in the transverse direction, a pipe with a longitudinal absorption slot is installed, the lower edge of which is immersed in water so that the upper layer of water merges into this slot together with light impurities that have surfaced in the washing bath. The amount of water that fuses light impurities can be adjusted by the depth of immersion in water of the lower edge of the absorption hole. To do this, the pipe is rotated relative to its axis with a special handle with a clamp and a pointing scale. One end of the pipe is closed by a plug, and the other passes through a hole in the wall and drains the water with light impurities into the sink sump. The described device provides almost complete removal of light impurities and minimal consumption of floating water. This solution is in the invention according to the copyright certificate 701708404, developed by specialists of the department TOZV. In addition, certain problems and inconveniences are caused by the design of the sieve shell of the squeezing column. Dirt particles tend to stick to the outer surface of the sieve cylinder and block its holes. This can slow down and even stop the separation of water by centrifugation. Therefore, the upper outer surface of the cylinder is washed with water, which in automatic mode is periodically fed to the sieve by the control device and the solenoid valve. It also saves water.

Numerical solution of the gas compression problem at a specified law of action

Выполнено численное моделирование одномерных течений политропного газа, описывающее сжатие покоящегося газа с плотностью 1 в покоящийся газ, сжатый до значения 10. Описываемое сжатие происходит без ударных волн эффективным с точки зрения энерговложения способом, так как энергия тратится только на сжатие газа, но не на его разгон Controlled thermonuclear fusion (CTF) is an almost unlimited source of energy and scientists have been studying it for several decades. This requires an efficient and stable compression of diyterium-tritium fuel to a very high density. This work addresses shockless one-dimensional (plane, cylindrical and spherical symmetry cases) “compression from rest to rest”, when gas from the initial resting state under the influence of an impenetrable piston is shocklessly transferred to a resting homogeneous state, but compressed by 10000 times. This compression is energetically most advantageous, because work is spent only on the compression, but not on the gas acceleration. Earlier [10] this problem was solved in the opposite direction of time change. In this case, a density jump occurs on the piston which was taken into account in calculations [3] at the final moment of compression. The numerical solution of this problem in the opposite direction of time variation allows calculating the trajectory of the compressing piston in the form of a set of points ( t,r ) at which the gas velocity and density are determined. In this paper, the problem of shockless “compression from rest to rest” is numerically solved in the forward direction of time change if the compressing piston trajectory is known. The compression piston moves along a monotonous trajectory away from the axis or center of symmetry. It is important, when calculating in forward direction of time change, no internal characteristics are initially entered. They, like all gas flow in the calculation area, are determined in the process of direct calculation. This indicates that the trajectory of compressing piston is the recommendation for appropriate physical experiments

Climate Change as a National Security Issue: Examining Framing Effects Across Party

Research suggests that framing climate change as a national security issue can shape opinion about climate change. This research is less clear about what exactly constitutes a “national security frame” and what aspects of this frame are most persuasive. We use a survey experiment to compare the relative effects of three types of national security frames we identify. Results show that a frame centered on energy dependence had the strongest effect and was the most consistent across partisanship. Surprisingly, the effects ran in the opposite direction for Democrats and Republicans on both outcomes—negative for Democrats and positive for Republicans. We also show that the energy dependence frame moderated the influence of respondents’ affect toward political candidates and parties on their climate change attitudes. The results suggest that the energy dependence frame can shape public opinion, but that it must be tailored to particular audiences to avoid backfire effects.

Evolutionary change in metabolic rate of Daphnia pulicaria in response to the invasive predator Bythotrephes longimanus

Metabolic rate is a trait that can be hypothesized to evolve in response to a change in predation. In the current study, we address this question by utilising an invasive event by the predatory zooplankton Bythotrephes longimanus in Lake Mendota, Wisconsin, US. This invasion dramatically impacted the prey Daphnia pulicaria, causing a ~60% decline in their biomass. Using a resurrection ecology approach, we compared the metabolic rate of D. pulicaria clones originating from prior to the Bythotrephes invasion with that of clones having evolved in the presence of Bythotrephes. We observed a 7.4% reduction in metabolic rate among post-invasive clones compared to pre-invasive clones. This change is in the opposite direction to what might be expected to evolve in response to increased predation. The evolution of a lower metabolic rate may instead be due to a habitat shift in the prey species into deeper and less productive waters and associated changes in the optimal metabolic rate.
