The skin is the largest organ in the body. Its function is to protect the body from potential harm and to maintain homeostasis. The epidermis is the outermost layer of the skin. Stratum corneum is the outermost layer of the epidermis, composed of corneocytes and surrounding lipids. The lipids are produced by different enzymes that all play a role in the formation and function of the skin permeability barrier. Mutations in genes coding for these enzymes can lead to barrier dysfunction and could cause autosomal recessive congenital ichthyosis (ARCI). Nine genes have been identified as ARCI-causative and two of them are CYP4F22 and CERS3. The purpose of this project was to study co-localization of CYP4F22 with CERS3 and also mutated CYP4F22 enzymes, by transfecting plasmids into HeLa and HaCaT cells and performing PLA on HEKn cells. Co-localization could indicate potential interactions and by studying these more in the future, novel treatment strategies can be developed for ARCI patients. Transfection attempts showed a low transfection grade of wild type genes in both HeLa and HaCaT cells. Tendencies towards co-localization was seen in both cell types and some HeLa cells showed strong correlation after image analysis. Transfection of mutated genes failed, unfortunately. PLA showed co-localization in normal keratinocytes. The obtained results indicated a co-localization, but results need to be confirmed by immunoprecipitation and immunoblotting in the future.

Fler och fler industrier vänder blickarna mot A.I. (artificiell intelligens) för att undersöka om och hur det kan användas för att effektivisera olika processer. Men för att träna upp en A.I. krävs oftast stora mängder data där man kan behöva förbereda väldigt mycket manuellt innan man ens kan påbörja träningsprocessen. SCA Skog AB ser dock många fördelar med att göra A.I. till en naturlig del av sin digitaliseringsprocess, där man bland annat är intresserad utav visuella bedömningar av träd. Dataset för visuella bedömningar kan se ut på olika sätt, men i detta fall var det relevant att skapa dataset i form av konturer för trädstammar. Med hjälp av en A.I. som skulle kunna visuellt segmentera och klassificera träd så skulle man öppna upp för många nya möjligheter inom skogsindustrin. Under detta projekt har jag undersökt hur man skulle kunna automatisera processen för skapandet av dataset i skogsmiljöer för just visuella bedömningar. Som ett resultat av att försöka uppnå detta, så fick jag experimentera med bildbaserade punktmoln som på olika sätt tillät projektet att avancera framåt. Ur dessa punktmoln kunde jag sedan segmentera träden för att i nästa process skapa konturer längs alla träd med hjälp av utvunnen data ur segmenteringen. Jag tittade först och främst på hur man automatiskt skulle kunna skapa konturer för alla träd i bildsekvensen, för att sedan låta en användare gå in och finjustera konturerna. I resultatet kan man sedan tydligt se skillnaden i tidsåtgång för att använda programmet och inte. Programmet kan skapa och uppdatera pixel-masker snabbare än vad jag manuellt kunde utföra samma arbete, där jag dock hade önskat på en mer markant skillnad i tidsåtgång jämfört med den rent manuella insatsen. Under projektets gång så kunde jag identifiera några större problem som förhindrade detta, där man med lämplig utrustning skulle kunna uppnå ett mycket bättre resultat än vad som gjordes under detta projekt. Resultaten talar ändå för att det kan vara lönt att undersöka metoden mer ingående.More and more industries are turning their eyes towards A.I. (artificial intelligence) and its rapid development, in hope of utilizing it to remove labor intense operations. But large amounts of manually processed data is often required before starting the learning process, which can be a huge problem to deal with. SCA Skog AB is still very curious in how they could use A.I. in forestry, where visual inspection of trees is of particular interest. There are many visual problems that modern A.I. can solve, where in this case it’s a matter of finding contours of trees and classify them. If this would be possible, a lot of interesting opportunities would open up to be experimented with. During this project I’ve examined the possibility of reducing the time it takes to manually create datasets of forest environments for this particular visual problem. As a result of trying to achieve this, I had to examine image-based point clouds and their properties to find out how they could be used in this process. From the SfM-point cloud I was able to segment all visible trees with an segmentation algorithm and isolate these points to extract the 2D→3Dconnection. I could then use that connection to create pixel masks and apply it to the image sequence to paint out all the contours of the segmented trees. A method to automatically update these pixel masks in terms of adding and removal was also implemented, where any update would propagate through the image sequence and reduce the time for manual adjustment. From testing the program, it’s clear that time could be saved doing various kinds of contour updating-operations. The program could by itself create pixel masks that then could be updated in a way that a lot of need for manual updating was reduced, though the result in terms of time saved was not as substantial as one would have hoped for. Issues with the point cloud caused some major problems due to it’s low precision. Using better equipment for image gathering would most likely be the best way to improve the results of this project. The result still tells us that this method is worth researching further.

Kim, Joowan. „The role of dynamics in the formation and maintenance of the tropical cold-point tropopause“. Thesis, McGill University, 2014. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=123213.

This thesis examines characteristics of the tropical cold-point tropopause (CPT)and associated dynamic mechanisms using observations, idealized model, and generalcirculation model simulations. Fine-scale structure of the CPT is investigated usingnewly available high-resolution temperature data. Then, the dynamic mechanism ofthe CPT formation is rigorously tested and examined using a dry primitive equationmodel under the framework of transformed Eulerian-mean. Finally, the characteristicsof the CPT are examined in the state-of-art climate models that participated inthe Coupled Model Intercomparison Project Phase 5 (CMIP5). The current climatemodels' capability to reproduce the CPT features is evaluated and discussed.In the observational study, climatology, seasonal cycle, and intraseasonal variabilityof three CPT properties (temperature, pressure, and sharpness) are examinedusing high-resolution temperature profiles derived from COSMIC global positioningsystem (GPS) radio occultation (RO) measurements. The climatology obtained fromthe GPS RO data captures the characteristic structure of the CPT successfully. Thethree CPT properties show coherent seasonal cycle in the tropics that the CPT iscolder, higher (lower in pressure) and sharper in boreal winter compared to that inboreal summer. This seasonality is consistent with that of the large-scale tropopauseupwelling, which is largely driven by near-tropopause processes. The variability onintraseasonal timescales is more likely controlled by the tropical deep convectionand associated tropical waves. Particularly, intraseasonal variability of the CPTproperties shows clear signature of Kelvin waves, with a secondary contribution byMadden-Julian Oscillation in the deep tropics.The formation mechanism of the CPT is further investigated using a dry primitiveequation general circulation model with a simplified thermal forcing. The simpledynamic system reproduces a distinct cold level at the top of the tropical troposphere,which is analogous to the CPT in the real atmosphere. The modeled CPT is primarilymaintained by adiabatic cooling due to upwelling at the tropical tropopause,and synoptic-scale wave forcing in the subtropical lower stratosphere is found as theprimary driver of the upwelling. Further investigation on the evolution mechanismsuggests that the formation of the CPT is a part of balancing process between waveforcings and mean flow response in the tropics, and this is likely an important processthat decides the vertical extent of the subtropical jet in the lower stratosphere.The thermal characteristics of the CPT examined in CMIP5 models exhibitreasonable agreements with observations. Historical simulations successfully capturethe spatio-temporal structure of the CPT on annual and seasonal timescales. The interannualvariability associated with El Ni˜no Southern Oscillation and intraseasonalvariability associated with equatorial waves are also roughly reproduced. However,many of the models still have overall warm bias near the CPT and non-negligiblebiases in the amplitude of variability in intraseasonal to interannual timescales. Inthe future projections based on the Representative Concentration Pathway (RCP)8.5 scenario, the models predict robust warming both at the 100-hPa and zero-lapseratelevels (estimated CPT), but cooling at the 70-hPa level. A weakened seasonalcycle in the temperature is also found in most models at both the 100- and 70-hPalevels, which could have an important implication for the stratosphere-troposphereexchange and related climate variability.Cette thèse examine les caractéristiques du point froid de la tropopause tropicale, "tropical cold-point tropopause" (CPT) et les mécanismes dynamiques associés en utilisant des observations, un modèle idéalisé ainsi qu'on model de circulation globale. La fine structure du CPT est évaluée en utilisant de nouvelles mesures de températures à haute résolution. Ensuite, les mécanismes dynamiques de la formation du CPT sont testées de manière rigoureuse et examinées en utilisant un model sec basé sur les équations primitives dans le cadre du "Transformed Eulerian Mean". Finalement, les caractéristiques du CPT sont examinées avec les modèles climatiques de pointe du "Coupled Model Intercomparions Project Phase 5" (CMIP5). La capacité actuelle de ces modèles de reproduire les caractéristiques du CPT sont par la suite évaluées.Dans l'étude observationnelle, la climatologie, le cycle saisonnier et la variabilité intra-saisonnière de trois propriétés du CPT (température, pression et finesse) sont examinées en utilisant des profils de température haute-résolution dérivés du system de mesure par radio occultation gps COSMIC. La climatologie obtenue par COSMIC capture la structure caractéristique du CPT avec succès. Les trois propriétés du CPT montrent une évolution saisonnière cohérente dans les tropiques : le CPT est plus haut, plus froid, et plus fin lors de l'hiver boréal compare à l'été boréal. Cette saisonnalité est consistante avec les mouvements verticaux de large échelle qui sont principalement générées par des procédés locaux à la tropopause. La variabilité intra saisonnière est plus vraisemblablement contrôlée par la convection tropicale profonde et les ondes tropicales associées. Particulièrement, la variabilité saisonnière du CPT montre clairement une signature d'onde Kelvin, avec une contribution secondaire de la Madden-Julian Oscillation dans les tropiques. Les mécanismes de formation du CPT sont par la suite évalués en utilisant un model basé sur les équations primitives avec un forçage thermal simplifie. Le système dynamique simple reproduit un niveau froid distinct au sommet de la troposphère tropicale, qui est analogue au CPT de l'atmosphère terrestre. Le CPT modelé est principalement maintenu par de refroidissement adiabatique par ascension à la tropopause tropicale. Le forçage par onde synoptiques dans la basse stratosphère subtropicale est le mécanisme dominant régissant ce refroidissement par ascension. Une évaluation plus poussée suggère que la formation du CPT fait partie d'un processus de stabilisation entre le forçage d'onde et la réponse de la circulation moyenne dans les tropiques et que ce processus est vraisemblablement important pour décider de l'étendue verticale du courant jet subtropical dans la basse stratosphère.Les caractéristiques thermales du CPT observées dans les modèles CMIP5 démontrent une correspondance raisonnable avec les observations. Les simulations historiques capturent avec succès la structure spatio-temporelle du CPT sur des bases annuelles et saisonnières. La variabilité interannuelle associée avec le « El Nino-Southern Oscillation» et la variabilité intra saisonnière associée avec les ondes équatoriales sont reproduites avec succès. Cependant, plusieurs des modèles présentent une erreur chaude près du CPT et des erreurs non-négligeables dans l'amplitude de la variabilité intra saisonnière et interannuelle. Dans la projection future basée dur le scenario « Representative Concentration Pathway » (RCP) 8.5, les modèles prédisent un réchauffement au niveau du CPT, mais un refroidissement à 70 hPa. Un cycle saisonnier de températures plus faible est aussi observé dans la plupart des modèles au niveau de 100 et 70 hPa, ce qui pourrait avoir des implications importantes pour les échanges stratosphère troposphère et la variabilité climatique associée.

Resumo: O presente trabalho foi realizado usando biodieseis preparados a partir de óleos de soja, canola, milho, girassol e, também, de gordura suína, através de reações transesterificação. Para todos esses biodieseis foram determinados o ponto de entupimento a frio, o ponto de fulgor e o perfil cromatográfico. Estes biodieseis foram misturados com diesel de petróleo para se produzir misturas contendo 5% do biocombustível (B5), 10% (B10) e 20% (B20), e os ensaios citados foram realizados nestas amostras. Visando a diminuição do ponto de entupimento a frio, alguns aditivos naturais foram testados e se mostraram eficientes. Por exemplo, o limoneno reduziu o ponto de entupimento do biodiesel de óleo soja em mais de 7°C. No biodiesel de gordura suína a redução foi de 10°C, o que significa o ponto de entupimento a frio em temperatura inferior a 13°C. Os aditivos utilizados são solúveis nos biodieseis estudados e, também, nas misturas diesel-biodiesel, pelo menos nas concentrações testadas. Como importante exemplo de abaixamento do ponto de entupimento a frio das misturas diesel-biodiesel de gordura suína com 10% de biodiesel (B10), podese citar o caso da terebentina que provocou uma redução de aproximadamente 8°C (de 12,7ºC para 5,0°C). Este mesmo aditivo caus ou uma redução de 13,6 ºC (de 20,3ºC para 6,7ºC), na mistura diesel-biodiesel de gordura suína com 20% de biodiesel (B20). Este resultado é muito significativo por implicar na possibilidade de usar este tipo de combustível mesmo em regiões mais ao sul do país durante o inverno
Abstract: The present studies were performed preparing biodiesel from soya, canola, corn, sunflower oils and the fat swine, through transesterification reaction. The biodiesel produced from these oils were studied for: cold filter plugging point, flash point and for chromatographic analysis. The biodiesels were mixed with diesel to produce blends containing 5% of the biofuel (B5), 10% (B10) and 20% (B20), and these samples were also analyzed by the same techniques as discussed earlier. In order to decrease the cold filter plugging point, some natural additives have been tested and were proved effectively. For example, limonene caused more than 7°C reduction in the cold filter plugging point of soybean biodiesel. In the biodiesel obtained from the swine fats, the reduction was found around 10°C and less than 13°C for the cold filter plugging point. The additives are soluble in studied biodiesels and also in the dieselbiodiesel blends, at least, in the concentrations tested. One of the important example of the reduction in the cold filter plugging point of diesel-biodiesel blends of swine fats with 10% biodiesel (B10), using turpentine as additive which caused reduction of approximately 8°C (from 12,7ºC up to 5,0°C). The same additive caused a reduction of 13,6 ºC (from 20.3 ºC up to 6.7 °C) in the cold filter plugging point of diesel -biodiesel blends of swine fats with 20% biodiesel (B20). This result is very significant because it is possible to use this type of fuel in south regions of the country during the winter

This Thesis is focused on the study of the problem of condensation on the inner surface of Fullrigaren building’s large single pane window. This has serious consequences as water on the floor, corrosion or mould growth. As the climate in Nordic countries is cold for several months a year, windows are a crucial part in building envelopes. Condensation on a window may be suitably discussed only with respect to the climate considered as cold, moderate and warm climates pose different requirements on the windows, and this is why a characterization of Gävle by its climate is necessary. This Thesis will include the energy analysis of the staircase considered which is required to understand the source of the actual problem. Both heat and moisture transfer will be studied. In this purpose, an IDA model will be built to simulate the conditions throughout the year and hand-made calculations will be done for the average and most critical situations. The results show that condensation will already occur for the monthlyaverage conditions having as an additional problem that if temperature drops below zero it will freeze. Results will also be compared to an initial installation of a 2 pane window reaching as a conclusion that its original installation would had avoided the problems for most of the time. The Thesis will end with several proposals posed to solve the problem by either increasing the temperature or reducing the moisture content of the ambient air, and the selection of the best one. The final aim of the Thesis is to achieve an energy efficient window which should provide good lighting during the day and good thermal comfort both during day and night at minimum demand of paid energy. And for this, the selection of the electrically heated window is proposed.

Este trabalho teve como objetivo avaliar o estádio de maturação, tipos de embalagens, uso de aditivos naturais e temperaturas de armazenamento de pêssegos „Aurora-1‟ minimamente processados visando sua qualidade e manutenção da vida de prateleira. Os frutos foram adquiridos em pomar comercial localizado no município de Taiúva-SP nos meses de outubro e novembro de 2007 e 2008. O trabalho foi dividido em cinco experimentos: no primeiro foram estudados estádios de maturação “de vez” e “maduro”. No segundo testou-se o efeito da aplicação de ácido ascórbico ou cloreto de cálcio. No terceiro verificou-se o efeito de embalagens como atmosfera modificada passiva. No quarto, foi verificado o efeito de temperaturas de refrigeração e tipos de cortes. No quinto testou-se o efeito da aplicação de ácido ascórbico, l-cisteína, ácido ascórbico e cloreto de cálcio, ácido cítrico e isoascorbato de sódio na prevenção do escurecimento enzimático. As análises de aparência, massa fresca, firmeza, coloração, composição gasosa, sólidos solúveis, acidez titulável, razão sólidos/acidez, pH, açúcares solúveis e redutores, pectina total e solúvel, solubilização, ácido ascórbico, atividade das enzimas peroxidase e polifenoloxidase foram efetuadas a cada três dias para os experimentos 1, 2, 3 e 5 e, a cada quatro dias para o quarto experimento. Frutos no estádio de maturação “de vez” levaram a produtos com melhor aparência e maiores teores de açúcares e de ácido ascórbico. Produtos tratados com ácido ascórbico a 2% apresentaram melhor aparência, maior conteúdo de açúcares e de ácido ascórbico, manutenção da cor e menor atividade enzimática. O filme de PVC 14 μm proporcionou boa conservação da aparência e prevenção do escurecimento dos produtos. A interação do armazenamento a 3 ºC e corte do fruto em oito fatias proporcionaram...
This study aimed to evaluate the maturation stage, packaging types, natural additives use and storage temperatures of minimally processed „Aurora-1‟ peaches in order to maintain their quality and shelf life. The fruits were purchased from a commercial orchard in the area of Taiúva-SP in October and November, 2007 and 2008. The work was divided in five experiments: in the first one, maturated green and maturated stages were studied. In the second one, it was tested the effect of ascorbic acid or calcium chloride application. In the third one, it was observed the packaging effect as passive modified atmosphere. In the fourth one, it was showed the effect of cooling temperatures and cutting types. In the fifth one, it was tested the effect of ascorbic acid, l-cysteine, ascorbic acid and calcium chloride, citric acid and sodium isoascorbate to prevent enzymatic browning. Analyses of appearance, fresh weight, firmness, color, gas composition, soluble solids, acidity, ratio, pH, soluble and reducing sugars, total and soluble pectin, solubilization, ascorbic acid, peroxidase and polyphenoloxidase activity were done each three days for the first, second, third and fifth experiments, and each four days for the fourth one. Matured green fruits led to products with better appearance and higher levels of sugars and ascorbic acid. Products treated with 2% ascorbic acid showed a better appearance, higher content of sugars and ascorbic acid, color maintenance, and lower enzymatic activity. 14μm PVC film use showed good appearance preservation and browning prevention of the products. Interaction between storage at 3°C and fruit cutting into eight slices provided the best product appearance, with a higher content of soluble solids. 1% Cysteine gave non-characteristic product odor, which limited its use.

Resumo: Este trabalho teve como objetivo avaliar o estádio de maturação, tipos de embalagens, uso de aditivos naturais e temperaturas de armazenamento de pêssegos „Aurora-1‟ minimamente processados visando sua qualidade e manutenção da vida de prateleira. Os frutos foram adquiridos em pomar comercial localizado no município de Taiúva-SP nos meses de outubro e novembro de 2007 e 2008. O trabalho foi dividido em cinco experimentos: no primeiro foram estudados estádios de maturação "de vez" e "maduro". No segundo testou-se o efeito da aplicação de ácido ascórbico ou cloreto de cálcio. No terceiro verificou-se o efeito de embalagens como atmosfera modificada passiva. No quarto, foi verificado o efeito de temperaturas de refrigeração e tipos de cortes. No quinto testou-se o efeito da aplicação de ácido ascórbico, l-cisteína, ácido ascórbico e cloreto de cálcio, ácido cítrico e isoascorbato de sódio na prevenção do escurecimento enzimático. As análises de aparência, massa fresca, firmeza, coloração, composição gasosa, sólidos solúveis, acidez titulável, razão sólidos/acidez, pH, açúcares solúveis e redutores, pectina total e solúvel, solubilização, ácido ascórbico, atividade das enzimas peroxidase e polifenoloxidase foram efetuadas a cada três dias para os experimentos 1, 2, 3 e 5 e, a cada quatro dias para o quarto experimento. Frutos no estádio de maturação "de vez" levaram a produtos com melhor aparência e maiores teores de açúcares e de ácido ascórbico. Produtos tratados com ácido ascórbico a 2% apresentaram melhor aparência, maior conteúdo de açúcares e de ácido ascórbico, manutenção da cor e menor atividade enzimática.

The fruits were purchased from a commercial orchard in the area of Taiúva-SP in October and November, 2007 and 2008. The work was divided in five experiments: in the first one, maturated green and maturated stages were studied. In the second one, it was tested the effect of ascorbic acid or calcium chloride application. In the third one, it was observed the packaging effect as passive modified atmosphere. In the fourth one, it was showed the effect of cooling temperatures and cutting types. In the fifth one, it was tested the effect of ascorbic acid, l-cysteine, ascorbic acid and calcium chloride, citric acid and sodium isoascorbate to prevent enzymatic browning. Analyses of appearance, fresh weight, firmness, color, gas composition, soluble solids, acidity, ratio, pH, soluble and reducing sugars, total and soluble pectin, solubilization, ascorbic acid, peroxidase and polyphenoloxidase activity were done each three days for the first, second, third and fifth experiments, and each four days for the fourth one. Matured green fruits led to products with better appearance and higher levels of sugars and ascorbic acid. Products treated with 2% ascorbic acid showed a better appearance, higher content of sugars and ascorbic acid, color maintenance, and lower enzymatic activity. 14μm PVC film use showed good appearance preservation and browning prevention of the products. Interaction between storage at 3°C and fruit cutting into eight slices provided the best product appearance, with a higher content of soluble solids. 1% Cysteine gave non-characteristic product odor, which limited its use. Minimally processed 'Aurora-1' peaches can be sold for up to nine days, when matured... (Complete abstract click electronic access below)

One of the core insights of Musil’s The Man Without Qualities is that there must be ‘a sense of possibility’. This chapter analyzes debates on the law applicable to cyberwar, as debates emanating from a sense of possibility, which translates into imageries of the way cyberwar might, could, or ought to happen, i.e. how possible future realities are construed. The analysis is limited to the Tallinn Manual on the International Law Applicable to Cyber Warfare. The basic point of much legal analysis is to make sense of new phenomena in terms of pre-existing legal rules, or, to make the unfamiliar, familiar. The creation of these legal imageries is contrasted with non-legal imageries of cyberwar, as found in military and security studies. The purpose of this exercise is to carve out more clearly what is particular about the way in which international lawyers have imagined the future in this domain.

The main idea behind this research paper is that modern information and communication technology could be better made to serve human beings, if we could specify more precisely the process of human thought and action. The cognitive stages of rational thinking has been studied from the user interface and product point of view but there does not seem to be any generally accepted model for the dynamics involved in cognitive stages in literature. In addition, a few studies have investigated the cognitive stages in rational thinking process from human centric point of view, i.e. how the skills are actually learned.

The storytelling device introduces the search for our roots, as persons and human beings. To write an autobiography is to seek our roots not only through retrospection, interpretation, and creation but through an act of profound freedom towards ourselves. To tell our story is to put back together the pieces of our existence and, in doing so, to re-build it. Recounting our work, at a certain point in our professional life, is like putting it back at the centre of our lives, it is like giving meaning to our actions, and starting to understand and interpret them again. This is why it is so important to recount our work, both for the narrator and the listen-er. From this point, we are trying to put in front of the educational perspectives the narration of the self as a central point of reflection on the knowledge, competences, and capabilities for entering into the world of work with responsibility, awareness, and a deep sense of citizen-ship. Following these indications, we thought that it could be a useful exercise to reflect on professionals’ stories in order to look inside the self. At the same time, we trust it is very im-portant for young adults transitioning into the world of work.

This chapter focuses on P. F. Strawson's need to address the question of whether acceptance of the truth of determinism would, could, or should lead people to use their resource to exempt everyone. It analyzes Strawson's beliefs that some or another framework of moral and interpersonal demands and expectations will be given with the fact of human society. It surmises that the content of demands and expectations must be set by the actual abilities of those in the society. The chapter also emphasizes how statistics matter in determining resource. It assesses the actual abilities that help in determining the content of the demands and expectations, including what counts as disregard or ill will.

What is the correct semantic account of “knows”? This is a hotly debated question in epistemology. Scholars have recently appealed to putative facts about the purpose of knowledge ascriptions to adjudicate this dispute. This chapter raises doubts about the viability of this strategy. A radical proposal is suggested, namely, that the entire debate about the semantics of “knows” mistakenly presupposes that we should account for the meaning of epistemic claims by determining their truth conditions. A more natural way to approach the meaning of epistemic claims, however, is to ask what practical functions they serve us in communicating with each other. Drawing on the work of J. L. Austin, this chapter articulates a view called “epistemic pragmatism.” If this proposal is correct, it will undercut a variety of popular theories and could potentially reorient contemporary debates about the semantics of knowledge ascriptions.

This chapter provides a new argument against epistemic relativism. Traditionally, epistemological investigation has aspired to general conclusions. According to the epistemic relativist, however, the cognitive norms that determine what counts as knowledge (or whether a belief is rational, justified, etc.) vary with, and are dependent on, local conceptual or cultural frameworks. In recent years, experimental philosophers have claimed to provide empirical evidence for this sort of epistemic diversity. This chapter argues that the data actually supports the existence of a universal folk epistemology. This idea is further supported by providing a theoretical argument for why language users living in social communities would develop a cross-culturally (and cross-linguistically) shared concept of knowledge. More specifically, it is argued that all humans have certain basic practical needs that the concept of knowledge is used to satisfy, and we could not meet these needs without a word that is (near-) synonymous with “know.”

Let’s move to a vantage point a little quieter: the surface of the moon. It is so still that Neil Armstrong’s footprints remain undisturbed. The only reason the US flag there appears to “fly” is that a wire holds it up. The moon and Mercury stayed still as Mars, Venus, and Earth moved on down the road of geological development. The moon is a “steady” environment, a word whose Middle English roots are appropriately tangled with the word for “sterile.” Nothing moves on the moon, but in its sky Mars, Venus, and Earth move in their orbits, just as they moved on in complexity 4 billion years ago. Out of the whole solar system, Mars and Venus are the most like Earth in size, position, and composition. Mars is smaller, but Venus could be Earth’s twin in size. If Earth and Venus were separated at birth, then something happened to obscure the family resemblance: liquid water brought life. To chemists, liquid is the third phase of matter, between solid and gas, and its presence made all the difference. Mars gleams a bright blood red even to the naked eye, while Venus is choked with thick yellow bands of clouds. Mars is cold enough to have carbon dioxide snow, while Venus is hot enough to melt tin and boil water. Earth’s blue oceans and green continents provide a bright, primary contrast. These three siblings have drastically different fortunes. At first, they looked the same, colored with black mafic basalt and glowing red magma. The original planets were all so hot that their atmospheres were driven off into space. The oceans and the air came from within. Steam condensed into oceans on each planet’s cool basalt surface. Oceans changed the planet. Water is a transformative chemical, small yet highly charged, seeping into the smallest cracks, dissolving what it can and carrying those things long distances. Venus, Earth, and Mars do not look like the moon because they have been washed in water. Mars is dry now, but the Curiosity rover left no doubt that the red planet was first blue with water.

In this paper, we discuss methods to efficiently render stereoscopic scenes of large-scale point-clouds on inexpensive VR systems. Recently, terrestrial laser scanners are significantly improved, and they can easily capture tens of millions points in a short time from large fields, such as engineering plants. If 3D stereoscopic scenes of large-scale point-clouds could be easily rendered using inexpensive devices, they might be involved in casual product development phases. However, it is difficult to render a huge number of points using common PCs, because VR systems require high frame rates to avoid VR sickness. To solve this problem, we introduce an efficient culling method for large-scale point-clouds. In our method, we project all points onto angle-space panoramic images, whose axes are the azimuth and elevation angles of head directions. Then we eliminate occluded and redundant points according to the resolutions of devices. Once visible points are selected, they can be rendered in high frame rates. Visible points are updated when the user stays at a certain position to observe target objects. Since points are processed on image space in our method, preprocessing is very fast. In our experiments, our method could render stereoscopic views of large-scale point-clouds in high frame rates.

The proposed paper is going to address the development of single point mooring FPSO (Floating Production, Storage and Offloading) monitoring and forecast system design. With 17 FPSOs deployed in both Bohai Bay and South China Sea, CNOOC owns one of the largest FPSO fleet in the world. Most of those FPSOs have been or will be moored to the seabed for decades. The extreme response during storm conditions could cause serious environmental problem, asset loss, personnel safety etc. In order to timely understand the tanker operation conditions and avoid potential risk of system failure when experiencing hurricanes, a monitoring and forecast system is developed for FPSO to monitor the environment conditions, tanker motions, green water, mooring tensions, FPSO heading and to predict the extreme mooring tensions and global motions before typhoon coming. The forecast system could further suggest the optimum loading condition for minimizing the extreme mooring tension and tanker motions to enhance the safe operation. In this paper, we take the Internal Turret Mooring FPSO 111 and the Submerged Soft Yoke Mooring FPSO 112 as the examples to introduce the design technology of the system. Through the integrated onboard interface information, the personnel could proactively take actions to mitigate the tensions on mooring lines and vessel motions. Furthermore, the measured mooring line tension, motion and environment history could assist the numerical studies of global performance. The details of designing or selecting the measuring and monitoring equipment, theory background of forecast system and the integrated onboard interface will be described.

In the fields of gear meshing research, biomedical and physical rehabilitation, the point-meshing force between single-point meshing objects needs to be recognized or understood to obtain some important and crucial information such as force’s changing course and transient friction force at some time. In fact, the measuring space was so very narrow that the single-point meshing force couldn’t be measured out expediently. Aim at solving this problem, a flexibly single-point force sensor was brought forward and devised. This sensor was fabricated out by silk-screen printing technologies. At the same time, the performance indexes of this sensor were measured and calculated, too. Testing parameters were minutely discussed and analyzed. Results showed that the performance indexes of the flexibly single-point force sensor could satisfy the actual measuring requirement of single-point touching objects.

Abstract In the Fall of 2018 Westinghouse designed a welded plug to repair a leak around a previously capped nozzle in the Boron Injection Tank at Indian Point Unit 3. The leak was caused by weld cracking around the nozzle. In order to complete the repair, the existing nozzle and weld needed to be removed by boring into the tank so that a custom plug could be installed. Due to site procedures, welding could not be performed inside the tank, so a single weld on the outside of the tank needed to be designed to meet ASME B&PV Code, Section III requirements. In addition, the tank was manufactured from carbon steel with a stainless steel cladding, so future corrosion of the carbon steel needed to be assessed. The leak was an outage related incident, which required the design to be expedited. This paper will discuss the technical challenges in designing the welded plug to meet the site and code requirements.

As a part of a reactor protection system in safety-related Distributed Control Systems (DCSs) applied in nuclear power plants, Point to Point Communications (PPC) mostly influence the response time of shutdown of a nuclear reactor. A new solution to improve efficiency for point to point communications is receiving increased attention. In this paper, a FPGA-based point to point communications system is proposed, which extremely enhances the communication efficiency for the network communication card with multi-ports. It also delivers a method to meet the requirement of high safety and reliability. In addition, the contribution of shortening the response time of shutdown of a nuclear reactor is presented, which is derived from analysing and calculating the response time based on FirmSys, the first DCS with safety class 1E produced by China with proprietary intellectual property. A validation scheme is also established for verifying the new proposed FPGA-based point to point communications system. The validated platform is built based on the current FirmSys system. The experimental data and calculated result are present in the article. In conclusion, it is proved that the FPGA-based point to point communications could be used to promote the efficiency of point to point communications and shorten the response time of shutdown of a nuclear reactor.

Ballistic shock, the strong vibrations that propagate through a vehicle structure after a ballistic impact, can damage electronic components that are mounted on various interior locations of the vehicle. To protect onboard critical electronic components from ballistic shock damage, predicted shock response spectra (SRS) are used as design guidelines in the selection of shock isolation devices. Current technology to predict shock response intensity at component mounting locations includes Finite Element Analysis, Statistical Energy Analysis, and various other modeling approaches. The Army Research Laboratory is implementing a process to determine component damage probability based on a numerical modal superposition method. This process allows detailed modeling of an entire vehicle (including instrumentation racks) but requires months of effort to perform skillful FEA modeling. Such an expenditure is acceptable only for unique high value vehicles, and is impractical for analysis of many vehicles. Therefore it is desirable to investigate alternative shock analysis methods that are simple and general (i.e., independent of specific vehicle configurations). Although such methods could entail reduced accuracy, for situations that are applicable they would eliminate the need of time-consuming finite element modeling, and could used in a variety of vehicles. As such, the methods could be used for “screening” for rapid identification of potential shock-damage issues. If necessary, further detailed analysis could be accomplished subsequently. When an armored vehicle is subjected to a non-perforating large-caliber munitions impact or blast, direct mounted components that are near the impact location will always risk the highest damage potential. Live fire ballistic tests and laboratory experiments as well as numerical modeling have proved this observation. The research presented in this paper develops, from an exact continuous model, a constant- and lumped-parameter, linear matrix model of a homogeneous, rectangular, simply-supported plate subject to transverse ballistic shock. The model is provided in a form suitable for eigen-analysis intended to yield kinematic responses for SRS determination. Damping can be included in either Rayleigh or modal form. The enabled “same-plate” shock analysis, while not encompassing an entire military vehicle, would treat the most severe cases of shock response, for components mounted directly on the impacted plate.

The year 2020 was very challenging for everyone due to the COVID-19 pandemic. Many people turn their lives upside down from day to day. Politicians had to impose completely unprecedented measures, and doctors immediately had to adapt to the huge influx of patients and the massive demand for testing. Of course, not all processes could be planned completely efficiently, given that the situation literally changes from minute to minute, but sometimes better planning could improve the real processes. This contribution deals with the application of simulation software SIMUL8 to the analysis of the COVID-19 sample collection process in a drive-in point in a hospital. The main aim is to create a model based on the real data and then to find out the suitable number of other staff (medics) helping a doctor during the process to decrease the number of unattended patients and their waiting times.

Advocates have long raised concerns about the potential for partner violence after a spouse’s or partner’s return from prison, but few programs or policies exist to prevent it. In an era in which experiences of incarceration and reentry—and by extension, experiences of a partner’s or coparent’s incarceration and reentry—are commonplace in low-income urban communities, the safety of families reuniting after a prison stay merits serious attention. The current study examines qualitative data from 167 reentering men and their partners to identify contextual influences on post-prison partner violence. Insights from the data offer a valuable starting point for future research and for considering how prevention could effectively target economic, physical, social, and cognitive conditions at multiple social-ecological levels.

We used eye tracking to measure visual attention to tobacco products and pro- and anti-tobacco advertisements (pro-ads and anti-ads) during a shopping task in a three-dimensional virtual convenience store. We used eye-tracking hardware to track the percentage of fixations (number of times the eye was essentially stationary; F) and dwell time (time spent looking at an object; DT) for several categories of objects and ads for 30 adult current cigarette smokers. We used Wald F-tests to compare fixations and dwell time across categories, adjusting comparisons of ads by the number of each type of ad. Overall, unadjusted for the number of each object, participants focused significantly greater attention on snacks and drinks and tobacco products than ads (all P<0.005). Adjusting for the number of each type of ad viewed, participants devoted significantly greater visual attention to pro-ads than anti-ads or ads unrelated to tobacco (P<0.001). Visual attention for anti-ads was significantly greater when the ads were placed on the store’s external walls or hung from the ceiling than when placed on the gas pump or floor (P<0.005). In a cluttered convenience store environment, anti-ads at the point of sale have to compete with many other stimuli. Restrictions on tobacco product displays and advertisements at the point of sale could reduce the stimuli that attract smokers’ attention away from anti-ads.

Do differences in port performance explain differences in maritime transport costs? How much would improvements in port performance reduce maritime transport costs in developing countries? To answer this question, we use a widely used transport cost model, but we provide a new measure of port efficiency, estimated through a non-parametric approach. Relying on data from the early 2000s, this paper shows that for a sample of 115 container ports in 39 developing countries, becoming as efficient as the country with the most efficient port sector would reduce average maritime transport costs by 5 percent. For the most inefficient country, the reduction in transport costs could reach 15 percent. These findings point out the potential gains that can be achieved from the combination of betterquality investment and more efficient service provision in the port sector. The estimates in this paper cannot be updated because the databases were discontinued and it therefore highlights the need to generate data to evaluate the effectiveness of public policies that are key to competitiveness.

For meat and meat products, secondary processes are those that relate to the downstream of the primary chilling of carcasses. Secondary processes include maturation chilling, deboning, portioning, mincing and other operations such as thermal processing (cooking) that create fresh meat, meat preparations and ready-to-eat meat products. This review systematically identified and summarised information relating to antimicrobial resistance (AMR) during the manufacture of secondary processed meatand meat products (SPMMP). Systematic searching of eight literature databases was undertaken and the resultantpapers were appraised for relevance to AMR and SPMMP. Consideration was made that the appraisal scores, undertaken by different reviewers, were consistent. Appraisal reduced the 11,000 initially identified documents to 74, which indicated that literature relating to AMR and SPMMP was not plentiful. A wide range of laboratory methods and breakpoint values (i.e. the concentration of antimicrobial used to assess sensitivity, tolerance or resistance) were used for the isolation of AMR bacteria.The identified papers provided evidence that AMR bacteria could be routinely isolated from SPMMP. There was no evidence that either confirmed or refuted that genetic materials capable of increasing AMR in non-AMR bacteria were present unprotected (i.e. outside of a cell or a capsid) in SPMMP. Statistical analyses were not straightforward because different authors used different laboratory methodologies.However, analyses using antibiotic organised into broadly-related groups indicated that Enterobacteriaceaeresistant to third generation cephalosporins might be an area of upcoming concern in SPMMP. The effective treatment of patients infected with Enterobacteriaceaeresistant to cephalosporins are a known clinical issue. No AMR associations with geography were observed and most of the publications identified tended to be from Europe and the far east.AMR Listeria monocytogenes and lactic acid bacteria could be tolerant to cleaning and disinfection in secondary processing environments. The basis of the tolerance could be genetic (e.g. efflux pumps) or environmental (e.g. biofilm growth). Persistent, plant resident, AMR L. monocytogenes were shown by one study to be the source of final product contamination. 4 AMR genes can be present in bacterial cultures used for the manufacture of fermented SPMMP. Furthermore, there was broad evidence that AMR loci could be transferred during meat fermentation, with refrigeration temperatures curtailing transfer rates. Given the potential for AMR transfer, it may be prudent to advise food business operators (FBOs) to use fermentation starter cultures that are AMR-free or not contained within easily mobilisable genetic elements. Thermal processing was seen to be the only secondary processing stage that served as a critical control point for numbers of AMR bacteria. There were significant linkages between some AMR genes in Salmonella. Quaternary ammonium compound (QAC) resistance genes were associated with copper, tetracycline and sulphonamide resistance by virtue of co-location on the same plasmid. No evidence was found that either supported or refuted that there was any association between AMR genes and genes that encoded an altered stress response or enhanced the survival of AMR bacteria exposed to harmful environmental conditions.

Accurate identification of the relationships between permafrost extent and landscape patterns helps develop airborne geophysical or remote sensing tools to map permafrost in remote locations or across large areas. These tools are particularly applicable in discontinuous permafrost where climate warming or disturbances such as human development or fire can lead to rapid permafrost degradation. We linked field-based geophysical, point-scale, and imagery surveying measurements to map permafrost at five fire scars on the Tanana Flats in central Alaska. Ground-based elevation surveys, seasonal thaw-depth profiles, and electrical resistivity tomography (ERT) measurements were combined with airborne imagery and light detection and ranging (LiDAR) to identify relationships between permafrost geomorphology and elapsed time since fire disturbance. ERT was a robust technique for mapping the presence or absence of permafrost because of the marked difference in resistivity values for frozen versus unfrozen material. There was no clear relationship between elapsed time since fire and permafrost extent at our sites. The transition zone boundaries between permafrost soils and unfrozen soils in the collapse-scar bogs at our sites had complex and unpredictable morphologies, suggesting attempts to quantify the presence or absence of permafrost using aerial measurements alone could lead to incomplete results. The results from our study indicated limitations in being able to apply airborne surveying measurements at the landscape scale toward accurately estimating permafrost extent.
