Authors: Carlaw Kirsten R , Carlaw Kirsten R , Fu Ng David Tok , Kim Dukyeon , Phillips Stephanie
Published: February 2022

Background: Pre-operative anxiety is prevalent and associated with adverse patient outcomes. Many anxiolytic techniques have been utilized in the pre-operative setting, with varying degrees of success. The Autonomous Sensory Meridian Response (ASMR) is an increasingly popular method of relaxation used for anxiety reduction in general society. It is a non-invasive, inexpensive intervention with no known adverse effects. It has not been researched in a pre-operative setting. We aimed to investigate the effects of ASMR in the pre-operative patient population.
Methods: This prospective, double-blind trial randomly allocated 50 participants into either a placebo or ASMR group. Pre-operative anxiety was compared before and after viewing specially formatted educational video information in either an ASMR or non-ASMR format with validated anxiety scales-Visual Analogue Scale (VAAS), Amsterdam Pre-operative Anxiety and Information Scale (APAIS) and State-Trait Anxiety Inventory. The physiological characteristics of heart rate and blood pressure were measured as secondary outcomes.
Results: The control group demonstrated a reduction in pre-operative VAAS of 6.6 (p = 0.01) and 1.1 (p = 0.02) on the APAIS. The ASMR group had a reduction of APAIS of 1.9 (p = 0.005) and no change in the VAAS. Changes in State-Trait Anxiety Inventory for state anxiety score were the same in both groups. Increased trait anxiety was correlated with increased post-intervention VAAS and APAIS scores. There was no effect of pre-existing trait anxiety and pre-interventional anxiety on the efficacy of ASMR. Post-intervention, there was a significant decrease in mean systolic blood pressure by 2.7mmHg in ASMR group. In multivariable analysis, ASMR group had a drop of 3.9mmHg in post-intervention systolic blood pressure compared to placebo (p<0.05).
Conclusion: While our findings are inconclusive, potential benefits of ASMR in reducing pre-operative anxiety should be further explored with a larger sample.

Authors: Coloni Rodrigo Dias
Published: February 2022

A busca por fontes alternativas para alimentação de aves e suínos está cada vez mais evidente, seja pela questão de diminuição de custos quanto pela segurança do ingrediente que será administrado na ração animal. Um subproduto bastante interessante é o farelo de girassol como um substituto do farelo de soja devido seu alto valor protéico. O farelo de girassol vem ganhando força principalmente, nas formulações de ração para aves e suínos. A região Centro-Oeste do Brasil concentra grandes indústrias que estão relacionadas com a extração de óleo confirmando com isso, uma produção expressiva de farelo de girassol. O grão de girassol é rico em óleo com alta concentração de ácidos graxos poliinsaturados sendo que o restante obtém-se o farelo que apresenta boa concentração de proteína e fibra. Esse concentrado protéico pode ser amplamente utilizado pelos produtores de acordo com sua disponibilidade e preço.

A agricultura familiar, além da importância fundamental na economia, proporciona uma série de benefícios para a sociedade como a geração de empregos, a preservação do meio ambiente, o desenvolvimento e a inclusão social, entre outros. Apesar disto, as escassas políticas de incentivo ao segmento refletem-se em índices inexpressivos de desenvolvimento do setor, o que reduz extremamente a competitividade do mesmo.
Prospectos para o cultivo de larva de lagosta
Authors: Igarashi Marco Antonio
Published: February 2022

A proposta desta revisão é resumir as informações sobre os estudos do cultivo de larvas filosomas. O desenvolvimento larval completo foi realizado no Japão para as lagostas espinhosas, Jasus lalandii, J. edwardsii, J. verreauxi e Palinurus elephas espécies de água temperada e Panulirus japonicus, espécie de água morna do Japão. Machos e fêmeas de lagostas espinhosas foram capturados na natureza e transportados para Sanriku, Japão. Estas lagostas espinhosas foram utilizadas para reprodução por vários e sucessivos anos de pesquisa em laboratório. A eclosão das larvas ocorreu anualmente na primavera e verão. As larvas recém eclodidas foram cultivadas em contêineres de 15, 30 e 100 l. O contêiner de cultivo foi conectado a um tanque de cultivo com microalga Nannochloropsis de 200 - 500 l. A água do cultivo recirculou entre ambos os tanques de cultivo. Os náuplios de Artemia foram utilizados como alimento durante o período inicial em combinação com pequenos pedaços de mexilhão M. edulis. O sucesso no desenvolvimento completo de várias espécies de larvas de lagostas espinhosas é provavelmente relacionado a microalgas Nannochloropsis e a alimentação com mexilhão M. edulis. O M. edulis foi nutricionalmente satisfatório para larvas de lagostas espinhosas. Pequenos pedaços de M. edulis foram pegas pelas larvas de lagostas com seus alongados pereiópodos. No caso da propagação de microalgas Nannochloropsis, a concentração de amônia foi mantida em uma quantidade negligível na água do cultivo. Sem a introdução de microalgas Nannochloropsis sp., o cultivo de larvas de lagosta espinhosa foi difícil por causa da ocasional ocorrência de fungo Saprolegnia sp., protozoa Vorticella sp. etc. Uma alta taxa de sobrevivência de lagosta espinhosa J. verreauxi de aproximadamente 10 % foi obtido de ovo a puerulus enquanto que houve alta mortalidade no 1° instar para P. elephas. Porém, o P. elephas pode ser considerado uma das mais promissoras espécies na aqüicultura por causa do seu ciclo larval curto de 65 dias enquanto que para outras espécies leva 200 - 300 dias. A condição de requerimentos ambientais e nutricionais para P. elephas pode ser diferente comparado com a Jasus e Panulirus.

Published: February 2022

Este projeto foi desenvolvido em uma comunidade rural na região de Viçosa – MG e trabalhou-se com uma associação de oito produtores rurais que instalaram um tanque de expansão comunitário para o armazenamento e resfriamento do leite. As propriedades caracterizadas pelo trabalho familiar e a atuação metodológica baseou-se em visitas técnicas para diagnóstico das condições de sanidade dos rebanhos e orientações para melhoria do manejo. Através dos exames clínicos e laboratoriais identificou-se que afetam o sistema produtivo e podem ser associados às condições de higiene das instalações, às técnicas manejo e às condições alimentares inadequadas. Verificou-se uma alta incidência de helmintoses (63%), mastite sub-clínica (53%) e babesiose e anaplasmose (17,5%), além da presença de tolerância aos carrapaticidas utilizados. Desta forma, como ferramentas de trabalho foram realizadas reuniões para discutir os problemas e a apresentação de um curso para orientá-los sobre os cuidados com os animais, como forma de auxiliar na questão econômica e na baixa qualidade e produtividade do leite produzido. A inexistência de práticas higiênicas preventivas para as enfermidades relaciona-se com a falta de políticas pública de saneamento no campo, estruturas mínimas de instalações e acesso destes produtores às informações, devido à falta de assistência técnica.

Authors: Hanif Hanif , Mukri Moh. , Susanto Is
Published: February 2022

Work ethic is a person's attitude and view at work, sourced from self-quality, realized based on values ​​and implemented in activities at work. A work ethic based on Islamic values ​​will form a Muslim full of responsibility and hard work in carrying out his duties at work. At a practical level, an understanding of the Islamic work ethic will have a major impact on work. The results of this study indicate that in general the understanding of the Islamic work ethic of the employees of UIN Raden Intan Lampung and IAIN Metro is in accordance with the theory of Islamic work ethic. However, in practice not all employees carry out an Islamic work ethic which includes work to seek sustenance, work is worship, work professionally, work hard, respect time (discipline), uphold honesty. According to the Islamic perspective, work is part of fulfilling the needs of life which are divided into primary, secondary and tertiary needs. These three needs are very important for the running of human life in general and humans in particular. If it does not work, then humans will naturally experience difficulties which will eventually fall into sin.

Environmental sustainability and ecological aesthetics experience a turbulent affair when academic language is replaced by an artistic register: can we articulate contemporary crises stemming from uncontrolled mobilities, such as hyper-consumption, hyper-automobilities, and technological pollution, better by replacing sociological analysis with affective poetic language? The following poem (unpublished but belonging to the theme of Altermodernities: A Traveller’s Notes, book 1: Anthropocene Entanglements) explores what this transition offers to a “public sociology” of modernity that relays theory to multiple publics in alternative visual and textual styles.

Published: February 2022

The construction of a Y-type urban rail transit line can effectively solve the problems of low line coverage and low utilization in suburban areas. The purpose of this paper is to study and analyze the effect of different operation modes of the Y-type line of suburban urban rail transit. In this paper, the objective function is to minimize value of passenger travel time costs and enterprise operating costs, and the main and branch train frequencies are used as decision variables to establish a selection model for Y-type operation mode, and design an improved multi-objective optimization algorithm based on NSGA-II. A case study was carried out on the Y-type line to evaluate the effect of each scheme. The results of the study found that there is no obvious difference between the advantages and disadvantages of the three operation modes. The passenger waiting time under the independent operation plan is the highest but the comfort level is greater, and the train travel distance is the lowest. The partial- through operation accommodates the interests of both passenger and business. Therefore, the corresponding operating mode should be selected according to the preferences of passengers and enterprises.
Categorical Description of Simple-Folding a Map
Authors: Jia Yiyang , Zhao Yan , Zhang Chao
Published: February 2022

To compensate for the lack of abstraction in the field of origami, in this paper, we propose a categorical description that can be introduced to map folding. Specifically, we use a particular expression to abstract the folding process of a map with logical matrices. When the folding operations are restricted to two certain kinds, the simple folds and the simple unfolds, we can define categories of partly folded states of the map as poset categories. The property of posets induces many general categorical concepts, such as (co)product, opposite category, direct system, and so on. We then introduce how these general concepts are specified in the proposed categories. These conceptions and specifications brought us the hope to solve and study the map folding with contemporary mathematical methods, such as the (co)homology. Furthermore, our categorical description can potentially be applied to a more generalized version of the map folding, the flat-folding.

Published: February 2022

The multi-layer directed network model focuses on portraying the directionality, diversity and difference of the edges in the network. It is also one of the powerful tools for analyzing the complexity of the network system and the heterogeneous interaction characteristics between network layers. This paper constructs three three-layer directed network models combined with traditional complex network theory and analyzes their degree distribution characteristics. By controlling the out-degree and in-degree of the middle-level nodes, a network structure with multi-peak characteristics is configured. Combined with numerical simulation, it is concluded that the number of links between the layers of the directed network makes the network characterize the characteristics of unimodal, bimodal, and trimodal; the combination of the optimal mechanism and the changes in the number of inter-layer links, the network characteristics show the coexistence of power law and unimodal. The research results of this paper have practical value for the analysis of network generation mechanism and correlation law by using multi-layer directed network theory in the era of big data.
Gully Identification of Debris Flow Disaster Based on Knowledge Distillation
Authors: Liu Kunxiang , Wang Baoyun
Published: February 2022

Convolutional neural networks have been applied in the field of remote sensing image classification. For convolutional neural networks with shallower layers and simpler structures, the accuracy of the recognition of debris flow gully images is not ideal, while the number of layers is deeper and the structure is relatively simple. More complex neural networks often consume a lot of system resources and are difficult to deploy on the user side. Aiming at this problem, an optimized convolutional neural network method is proposed. First, through multiple sets of comparative experiments, select Resnet101 and Resnet18 models with good image classification performance; then, use the characteristics of debris flow gully images to pre-train the deeper and more complex Resnet101 model; finally, through the method of knowledge distillation, The trained “knowledge” is extracted into the Resnet18 model to achieve the effect of improving accuracy while reducing system resource occupation. Experimental data shows that after using knowledge distillation, the accuracy and sensitivity of the Resnet18 model are increased by 2.36 and 1.72 percentage points, respectively, and the image processor occupancy is reduced by 37 percentage points compared with the Resnet101 model.

Published: February 2022

Considering the cost considerations and data maintenance ability in the traffic field, traffic managers only collect only the traffic data of a few important road network nodes and road network sections, and the relevant data of the missing secondary sections will affect the fine research of the road network. So this paper proposes a method based on multiple source data, which firstly performs the vehicle trajectory reconstruction and location positioning with the idea of minimum cost and maximum flow, and then calculates the average speed based on this, and all the results are tested by actual data. The experimental results show that the trajectory reconstruction algorithm is about 90% efficient, and the road average speed estimation result meets the actual situation.

Published: February 2022

Aiming at the problem of large deformation geometric nonlinearity of high aspect ratio wing/multi external storage system affected by aerodynamic, multi external storage and gravity loads, the nonlinear aeroelastic motion equation of wing is established by using medium deformation beam theory and quasi steady aerodynamic model, and the effects of geometric nonlinear deformation of high aspect ratio wing/multi external storage system on structural modal frequency Influence of vibration mode and flutter characteristics.The analysis results show that the influence of geometric nonlinear effect is mainly reflected in the first-order mode of lead-lag, and its flutter mechanism is flexural torsional coupling flutter dominated by the first-order mode of lead-lag. The random wing/multi plug-in system changes from vertical downward bending state to horizontal state, the influence of geometric nonlinear effect is weakened, and the amplitude of the first-order mode shape of lead-lag increases, Moreover, the variation trend of the first-order lead-lag and torsional modal frequencies slows down, which correspondingly reduces the variation amplitude of flutter velocity at the corresponding angle of attack, which shows that it has a certain positive effect on the flutter velocity by slowing down the geometric nonlinearity of the wing/multi plug-in system.

Published: February 2022

The motion of common rail injector needle valve and the hydraulic process of fuel control circuit are studied by using simulation method. The simulation model is verified by comparing the injection rate curve. The results demonstrate that the lifting of the injector ball valve changes the fuel flow in the control chamber, leading to two different speed stages as the needle valve is opened. The seating of ball valve changes the clearance between the ball valve and the valve seat, and the needle valve closing motion curve slope remains unchanged. The increase of rail pressure affects the needle valve motion speed at the rapid opening stage. When the rail pressure reaches a certain valve, it no longer affects the motion characteristics of the needle valve. The change of fuel inlet hole diameter affects the needle valve rapid opening and closing movement. The change of fuel outlet hole diameter mainly affects the closing movement of needle valve.

Dirigido por Tony Scott, o filme traz uma áurea sombria que circunda os personagens principais. O diretor até então fazia trabalhos na área de publicidade e propaganda, destinadas a comerciais televisivos e clips musicais, este fato é demonstrado na estética do filme, que possui uma fotografia escura, somada a alguns elementos de cena que compõem o exagero, além de algumas inserções de aparições da banda punk Bauhaus, que canta a música Bela Lugosi’ s dead, um hino gótico sobre o vampirismo. Com figurino produzido por Milena Canonero (conhecida por seus trabalhos com Kubrick) e premiada com o Oscar por seus figurinos no filme Carruagens de fogo (1981), os personagens se apresentam com uma indumentária típica da subcultura gótica, e dos jovens Yuppies. Há uma parceria com Yves Saint Laurent que faz o figurino de Miriam; unido características de uma mulher forte, e clássica; trazendo uma conotação de empoderamento da personagem perante a trama.

Feimer László (1896–1954) az egyik legkitűnőbb hídtervező mérnök, aki valaha a magyar katonaság kötelékében tevékenykedett. Az általa megalkotott „K”-híd olyan szerkezet, amely gyorsan, előre elkészített anyagokból, állványzat nélkül, csavarozással szerelhető híd volt, elsősorban katonai célra. A hídszerkezet magasságának változtatásával (egy, két vagy három sor építésével) 50, 80 és 105 méteres nyílások áthidalására is alkalmas volt. Feimer László munkásságával örökre beírta magát a hídépítés történetébe.
Energiapolitikai versengés új felállásban Délkelet-Európában: az Európai Unió az Egyesült Államokkal és Oroszországgal szemben?
Authors: Deák András , Szabó John , Weiner Csaba

A délkelet-európai országok hagyományosan a fennálló energetikai status quo megőrzésére törekednek. Ezt egyaránt indokolják az energia megfizethetőségét illető félelmeik, az alacsony fogyasztói árak fenntartásának vágya, a beruházások évtizedes elmaradása és a szén magas aránya energiamérlegükben. Mindamellett fejlődési pályájukat meghatározzák a külső tényezők, így napjainkban a dekarbonizációs törekvések is. Ez a cikk azt vizsgálja, hogy az Európai Unió kivonulása a fosszilis fűtőanyagok, legújabban a földgáz támogatásából milyen tudatos módon befolyásolja a régiós országok energiapolitikáját, illetve miként teszi az Uniót is akaratlanul geopolitikai szereplővé. Az Európai Unió új keletű gázellenessége szembe megy az orosz és amerikai érdekekkel, az utóbbiak továbbra is támogatják a földgáz elterjedését a térségben. Ezért kétpólusú (EU/Egyesült Államok – Oroszország) és egydimenziós (geopolitikai) elrendezés helyett háromszereplős (EU – Egyesült Államok – Oroszország) és kétdimenziós (geo- és klímapolitikai) helyzet van kialakulóban. A cikkben három eltérő esettanulmányt mutatunk be. Görögország sikeresen vezeti ki a szenet a földgázra és a megújuló energiákra alapozva. Ezzel szemben Bulgária fejlődési pályája bizonytalan, vitatottak nukleáris és gázipari tervei. Észak-Macedónia nem EU-tagként mérsékelt kényszerekkel szembesül, amelyek főleg a helyi szénvagyon kimerüléséből és a földgázfejlesztések lehetőségéből adódnak.

Due to the shortage of personal protective equipment during the COVID-19 pandemic, homemade face coverings were recommended as alternatives. However, the capability of alternative face coverings to proliferate microbes have not been fully documented. The current study evaluated bacterial load and proliferation associated with the use of common face masks during
the COVID-19 pandemic. Mask type-specific and surface-related bacterial load and pattern were noticeable in the study. Results indicated that roadside masks are among samples that contained relatively higher initial bacterial load. The highest number of bacterial forming colonies were observed in the inner surface of mask samples. Proliferation of microbes over time was also noticeable among the non-certified face coverings included in the study. Sterilization or washing of non-certified fabric face masks before use is recommended.
Web lateral instability caused by nonuniform paper properties
Authors: PARENT FRÉDÉRIC , HAMEL JEAN , MCDONALD DAVID
Published: February 2022

Lateral or cross-machine direction (CD) web movement in printing or converting can cause problems such as misregistration, wrinkles, breaks, and folder issues. The role of paper properties in this problem was
studied by measuring lateral web positions on commercial printing presses and on a pilot-scale roll testing facility (RTF). The findings clearly showed that CD profiles of machine direction (MD) tension were a key factor in web stability. Uneven tension profiles cause the web to move towards the low-tension side. Although extremely nonuniform tension profiles are visible as bagginess, more often, tension profiles must be detected by precision devices such as the RTF. Once detected, the profiles may be analyzed to determine the cause of web offset and weaving problems. Causes of tension profiles can originate from nonuniform paper properties. For example, by means of case studies, we show that an uneven moisture profile entering the dryer section can lead to a nonuniform tension profile and lateral web movement. Time-varying changes in basis weight or stiffness may also lead to oscillations in the web’s lateral position. These problems were corrected by identifying the root cause and making appropriate changes. In addition, we developed a mathematical model of lateral stability that explains the underlying mechanisms and can be used to understand and correct causes of lateral web instability

Published: February 2022

La imprenta en Aguascalientes se estableció en 1826, pero la consolidación de la cultura impresa y su permanencia, entre 1835 y 1870, se logró gracias a los Chávez. Esta historia de la imprenta es también la historia de una familia que jugó un papel clave en el establecimiento de las artes gráficas, la cultura impresa y su circulación en un periodo entre la búsqueda por la autonomía de Aguascalientes, las invasiones extranjeras y las guerras liberales-conservadoras. Esta investigación está centrada en la figura de José María Chávez y su labor como introductor de la gráfica y promotor de la literatura, las artes y la tecnología que repercutió en varios ámbitos de la vida local, lo que lo llevó a convertirse en un agente cultural imprescindible en la entidad.
Nordic Homicide in Deep Time: Lethal Violence in the Early Modern Era and Present Times

Nordic Homicide in Deep Time draws a unique and detailed picture of developments in human interpersonal violence and presents new findings on rates, patterns, and long-term changes in lethal violence in the Nordics. Conducted by an interdisciplinary team of criminologists and historians, the book analyses homicide and lethal violence in northern Europe in two eras – the 17th century and early 21st century. Similar and continuous societal structures, cultural patterns, and legal cultures allow for long-term and comparative homicide research in the Nordic context. Reflecting human universals and stable motives, such as revenge, jealousy, honour, and material conflicts, homicide as a form of human behaviour enables long-duration comparison. By describing the rates and patterns of homicide during these two eras, the authors unveil continuity and change in human violence. Where and when did homicide typically take place? Who were the victims and the offenders, what where the circumstances of their conflicts? Was intimate partner homicide more prevalent in the early modern period than in present times? How long a time elapsed from violence to death? Were homicides often committed in the context of other crime? The book offers answers to these questions among others, comparing regions and eras. We gain a unique and empirically grounded view on how state consolidation and changing routines of everyday life transformed the patterns of criminal homicide in Nordic society. The path to pacification was anything but easy, punctuated by shorter crises of social turmoil, and high violence. The book is also a methodological experiment that seeks to assess the feasibility of long-duration standardized homicide analysis and to better understand the logic of homicide variation across space and over time. In developing a new approach for extending homicide research into the deep past, the authors have created the Historical Homicide Monitor. The new instrument combines wide explanatory scope, measurement standardization, and articulated theory expression. By retroactively expanding research data to the pre-statistical era, the method enables long-duration comparison of different periods and areas. Based on in-depth source critique, the approach captures patterns of criminal behaviour, beyond the control activity of the courts. The authors foresee the application of their approach in even remoter periods. Nordic Homicide in Deep Time helps the reader to understand modern homicide by revealing the historical continuities and changes in lethal violence. The book is written for professionals, university students and anyone interested in the history of human behaviour.
