Para elucidar fatores que poderiam estar condicionando esse dimorfismo nos Didelphidae, foi analisada também a evolução de outros dois elementos: alometrias entre tamanho e forma do crânio e da mandíbula; e bionomia das mesmas 31 espécies. Foi realizado um mapeamento de todos estes caracteres, qualitativos e quantitativos, sobre uma filogenia da família, reconstruindo seus estados ancestrais utilizando métodos de parcimônia. Foram feitas também correlações utilizando contrastes independentes dos dados de dimorfismo sexual para auxiliar a esclarecer os padrões evolutivos do dimorfismo sexual. Tais correlações foram significativas, indicando coevolução entre os tipos de dimorfismo em ambas as estruturas estudadas. Não houve tendência unidirecional de surgimento/desaparecimento e aumento/decréscimo do dimorfismo nos Didelphidae. As reconstruções também indicaram coevolução entre os dimorfismos. Poucas espécies são altamente dimórficas e a maioria apresenta dimorfismo sexual de forma. Os resultados de alometrias entre os sexos foram iguais para crânio e mandíbula, mas elas também não apresentam padrão geral em direção à igualdade ou diferenciação das mesmas entre os sexos. Ambos os estados estão uniformemente distribuídos na filogenia. O comportamento das alometrias no crânio e na mandíbula coevoluiu, mas o padrão de alometrias entre os sexos não é conservado dentro de Didelphidae e não coevoluiu com o dimorfismo sexual, indicando que não explica a evolução deste caráter. Outros fatores, não-alométricos, devem condicionar este caráter nessa família. No entanto, apesar de padrões aparecem dentro de alguns clados, não há também evidência de coevolução entre bionomia e dimorfismo sexual nos Didelphidae. Espécies asazonais são poucas e não dimórficas de tamanho, talvez pelo fato de se reproduzirem continuamente e sofrerem menores pressões seletivas. A semelparidade é rara dentro de Didelphidae, surgindo apenas em Monodelphini e seguindo daí caminhos evolutivos distintos. Espécies semélparas exibem maiores tamanhos de ninhada nos Didelphidae por se reproduzirem uma única vez. Acredita-se que a seleção sexual direcione o padrão de dimorfismo sexual onde os machos são maiores que as fêmeas em espécies semélparas de Didelphidae. Portanto, nem alometrias nem bionomia, a princípio, explicam nem condicionam a evolução do dimorfismo sexual nos didelfídeos. A inclusão de uma maior quantidade de dados reprodutivos de marsupiais didelfídeos seria ideal para testar a veracidade da ausência de coevolução entre estratégias bionômicas e dimorfismo sexual. Associar dados ecológicos ou de padrões de distribuição poderiam ajudar a compreender melhor a evolução das estratégias bionômicas e a sua importância sobre a evolução do dimorfismo sexual nos Didelphidae. / The evolution of size and shape sexual dimorphism of the skull and mandible was studied in 31 taxa of didelphid marsupials, in order to better understand the development of this character in the family. And to elucidate factors that could be conditioning this dimorphism in Didelphidae the evolution of two other elements was also analyzed: allometries between size and shape of the skull and mandible and bionomy of the same 31 species. A mapping of all these qualitative and quantitative characters was carried through on a phylogeny of the family, reconstructing its ancestral states using parsimony methods. Correlations using independent contrasts of the sexual dimorphism data had been made also to assist clarifying the evolutionary standards of the sexual dimorphism. Such correlations were significant indicating coevolution among types of dimorphism in both studied structures. There is no unidirectional trend of sprouting/disappearance and increase/decrease of the dimorphism in Didelphidae. The reconstructions had also indicated coevolution among dimorphisms. Few species are highly dimorphics and the majority of them present shape sexual dimorphism. The results of allometries between the sexes had been the same for skull and mandible, but they also did not present a general pattern directing to the equality or differentiation between the sexes. Both states are uniformly distributed in the phylogeny. The results of the allometries in the skull and mandible coevoluted but the results of allometries between the sexes was not manteined in Didelphidae and they did not coevolute with sexual dimorphism indicating that they do not explain the evolution of this character and that other non-allometric factors must condition this character in this family. Although patterns appear inside of some clades there was no evidence of coevolution between bionomy and sexual dimorphism in Didelphidae. There are few aseasonal species and they are non-sized dimorphics perhaps by reproducing continuously and suffering less selective pressures. The semelparity is rare in Didelphidae arising only in Monodelphini and following from there distinct evolutionary ways. Semelparous species display the largest offspring size by reproducing only once. It is known that sexual selection directs the patterns of sexual dimorphism in those species in which males are larger than females in semelparous taxa of Didelphidae. Therefore neither allometries nor bionomy at first explain the evolution of sexual dimorphism in didelphids. The inclusion of a larger amount of reproductive data for didelphid marsupials would be ideal to test the veracity of the absence of coevolution among bionomic strategies and sexual dimorphism. The association of ecological data or distributional patterns could help in better understanding the evolution of the bionomic strategies and its importance on the evolution of the sexual dimorphism in Didelphidae.

Few studies have explored the relative strength of ecogeographic versus lineage-specific effects on a global scale, particularly for poikilotherms, those organisms whose internal temperature varies with their environment. Here, we compile a global dataset of life history traits in Daphnia, at the species-and population-level, and use those data to parse the relative influences of lineage-specific effects and climate. We also compare the thermal response (plasticity) of life history traits and their dependence on climate, temperature, precipitation, and latitude. We found that the mode of evolution for life history traits varies but that the thermal response of life history traits most often follows a random walk model of evolution. We conclude that life history trait evolution in Daphnia is not strongly species-specific but is ecogeographically distinct, suggesting that life history evolution should be understood at the population level for Daphnia and possibly for other poikilotherms.

Urbana miljöers komplexitet och rörelse kräver noga planerad ljussättning och omsorgsfull prioritering i samspelet mellan att lyfta fram viktiga element och lämna andra åt sidan. För att minska risken för överbelysning genom ljussättning av objekt med stor ljushetskontrast mot dess bakgrund bör alternativa metoder för att framhäva landmärken i stadsrum utredas. Detta examensarbete undersöker hur upplevelsen av mindre urbana landmärken påverkas av ljushetskontraster i dess bakgrund. Studiens syfte är att undersöka hur landmärkenas bakgrundsbelysning utformas idag, samt hur framhävning av landmärken påverkas av ljuskontrasten i dess bakgrund. Genom att använda ljussättning av landmärkenas bakgrundsmiljö som ett verktyg, syftar studien till att bidra till att skapa en tydlig och lättförståelig orientering genom stadsmiljön under mörka timmar.  Studien genomfördes i tre delmoment genom ett fältexperiment, intervjuer och ett kvasi-experiment. Observation av utvalda urbana objekt och dess omgivning genomfördes i fältexperimentet. Detta följt av två semistrukturerade intervjuer kring ljusdesigners beaktningstagande av bakgrunden vid ljussättning av landmärken i urban miljö. Vid observation av studiens kvasi-experiment analyserades generella miljöer med olika bakgrundsprinciper i en iscensatt urban miljö.  Resultaten av studien visar att olika stort beaktningstagande tas angående ljussättningen av urbana objekts omgivning, beroende på tidigare erfarenhet av ljusplanering. Studiens kvasi-experiment visade att ljushetskontrasten mellan ett urbant objekt och dess bakgrund, tillsammans med ljushetskontraster och formen på ljusbilderna inom bakgrunden, påverkar hur objektet uppfattas. Resultaten indikerar att en ljussättning av en urban miljö, med hänsyn till ovanstående faktorer, har påverkan på upplevelsen av objekten i miljön. Då bakgrunden är ljussatt lågmält, symmetriskt och då hela bakgrunden är definierbar ges en uppfattning om den omgivande miljön, vilket gör att objektet framhävs. / The complexity and movement of urban environments require carefully planned lighting and prioritization in the interplay between highlighting important elements and leaving others aside. In order to reduce the risk of over-lighting by lighting objects with a large brightness contrast against their background, alternative methods for highlighting landmarks in urban spaces should be investigated. This thesis examines how the experience of smaller urban landmarks is affected by brightness contrasts in its background. The purpose of the study is to investigate how the background lighting of landmarks is designed and is being designed today, as well as how highlighting of landmarks is affected by the light contrast in its background. By using lighting of the landmarks background environment as a tool, the study aims to help create a clear and easy-to-understand orientation through the urban environment during dark hours.  The study was carried out in three phases through a field experiment, interviews and a final quasi-experiment. An observation of selected urban objects and their areas was carried out in the field experiment, followed by two semi-structured interviews regarding lighting designers consideration of the background when lighting landmarks in an urban environment. When observing the studys quasi-experiment, general environments with different background principles were analyzed in a staged urban environment.  The results of the study show that varying degrees of consideration are taken regarding the lighting of urban objects surroundings, depending on previous experience with lighting planning. The studys quasi-experiment showed that the brightness contrast between an urban object and its background, together with brightness contrasts and the shape of the light images within the background, affects how the object is perceived. The results indicate that the lighting of an urban environment, taking these factors into account, has an impact on the experience of the objects in the environment. When the background is lit softly, symmetrically, and when the entire background is definable, an idea of the surrounding environment is given, which makes the object emphasized.

The monographic thesis mainly solves poetry and prose of Josef Mach, the Czech writer, journalist and clerk. It watches literary progress of his poetics according to the era context, influenc of places, historical and social events and inspirations of other artists who surrounded him. The work look into the texts and lyrics by a diachronic and synchronic way. The section about his original works is followed by a chapter about translations of several novels, because he acted even on this literary field. Then the general outline of the reception of Mach's personality and works since the time of his life until today. The whole thesis is introduced by Mach's biography to which it returns in many topics because his works have an empiric character and it is closely connected to the life. The object of the thesis is to sum information about all these topics and give it as a base for future expert research.

Det finns studier som anger rekommendationer för att designa en väl utformad restaurangmeny. Syftet med rapporten är att undersöka om pizzeriapersonal och formgivare designar digitala pizzamenyer genom medvetna val utifrån de designprinciper och designrekommendationer som finns. Undersökningen är ett kvalitativt forskningsarbete där kartläggning har använts som strategi. Datainsamlingsmetoderna som har använts är litteratursökning, visuell innehållsanalys, gruppintervjuer och semistrukturerade intervjuer för att kunna besvara frågeställningarna. Resultaten från undersökningen påvisar bland annat att pizzeriapersonalen anser att deras menydesign inte överensstämmer med varumärket. Personalen och kunderna har även olika uppfattningar om vad varumärkena står för. Trots att pizzeriornas varumärke inte stämmer överens med designen uppfyller menyerna kundernas förväntan. Slutsatserna visar bland annat att det finns gemensamma och särskiljande grafiska element. De flesta lågprispizzerior har inte ett genomtänkt varumärke samt att det inte finns en medvetenhet angående de designprinciper och designrekommendationerna hos pizzeriapersonal eller formgivare. / For the creation of restaurant menus there are studies that show which recommendations you should use to achieve a well-designed menu. The purpose of the study is to investigate whether pizzeria personnel and designers create digital pizza menus consciously from the design recommendations that exists. This study is a qualitative research work and we have used a survey as strategy. Data collection methods that have been used to answer the study questions are literature search, a visual content analysis, group interviews and semi-structured interviews. One result from the interviews showed that the pizzeria personnel thinks that their menu design does not match their brand. The pizzeria personnel and customers have different perceptions about what the brand stands for. The group interviews show that the digital menus live up to customers expectation and their experience of the low-price pizza. The conclusions show that there are common and distinctive graphical elements. Most low-price pizzerias do not have a well thought out branding, although the pizzeria personnel and designers do not have consciousness regarding the design principles and recommendations.

Interiör inredning i bilar idag är en faktor som konsumenter värderar högt. För att sticka ut i marknaden krävs det att alla delar upplevs högkvalitativa. Det medför att det ställs allt större krav på interiöra komponenter i bilen. Studien är i samarbete med Volvo Cars och mer specifikt deras Perceived Quality-avdelning då det är denna avdelning som fokuserar på upplevd kvalité och arbetar för att Volvo Cars bilar ska upplevas högkvalitativa. En viktig del av den interiöra inredningen är belysning. Denna studie har som mål att besvara hur stora differenser det kan vara på luminansnivåer innan det mänskliga ögat märker skillnad. De metoder som använts är observationer och experiment. Observatörer blev visade fyra olika lysande punkter där deras uppgift var att förklara när de upplevde skillnad samt hur de upplevde skillnaderna. Mätdata insamlades med luminanskamera som sedan analyserades. Data som insamlades redovisades och analyserades. Data användes sedan för att påvisa hur mycket luminansnivåer interiört i bilar kan differera innan skillnad upplevs. / Interior design in cars today is a factor that consumers value highly. To stand out in the market, it is required that all parts are experienced as high quality. This entails that there are increasing demands on interior components in the car. The study is in collaboration with Volvo Car Group and specifically their Perceived Quality department as it is this department that focuses on perceived quality and works to ensure that Volvo Car Group´s cars are perceived as high quality. An important part of the interior design is lumination. This study aims to answer how large differences there can be at luminance levels before the human eye notices a difference. The methods used are observations and experiments. Observers were shown four different luminated points where their task was to explain when they experienced difference and how they experienced the differences. Measurement data were collected with a luminance camera which was then analyzed. Data collected were reported and analyzed. Data were then used to show how much luminance levels interior in cars can differ before a difference is experienced.

Fish encounter daily cycles of hypoxia in the wild, but the physiological strategies for coping with repeated cycles of normoxia and hypoxia (intermittent hypoxia) are poorly understood. Contrastingly, the physiological strategies for coping with continuous (constant) exposure to hypoxia have been studied extensively in fish. The main objective of this thesis was to understand how Fundulus killifish cope with a diurnal cycle of intermittent hypoxia, an ecologically relevant pattern of aquatic hypoxia in the natural environment. To do this, I characterized the effects of intermittent hypoxia on hypoxia tolerance, oxygen transport, metabolism, and the oxidative stress defense system of killifish, and compared these effects to fish exposed to normoxia, a single cycle of hypoxia-normoxia, and constant hypoxia. Specifically, I studied the following topics: (i) how acclimation to intermittent hypoxia modifies hypoxia tolerance, and the hypoxia acclimation response of Fundulus heteroclitus (Chapter 2), (ii) metabolic adjustments occurring during a hypoxia-reoxygenation cycle (Chapter 3), (iii) how acclimation to intermittent hypoxia alters O2 transport capacity and maximal aerobic metabolic rate (Chapter 4), (iv) the effects of hypoxia and reoxygenation on reactive oxygen species and oxidative stress (Chapter 5), and (v) variation in hypoxia tolerance and in the hypoxia acclimation responses across Fundulus fishes (Chapter 6). Killifish rely on a unique and effective physiological strategy to cope with intermittent hypoxia, and that this strategy is distinct from both the response to a single bout of acute hypoxia-reoxygenation (12 h hypoxia followed by 6 h reoxygenation) and to chronic exposure to constant hypoxia (24 h hypoxia per day for 28 d). Key features of the acclimation response to intermittent hypoxia include (i) maintenance of resting O2 consumption rate in hypoxia followed by a substantial increase in O2 consumption rate during recovery in normoxia, (ii) reversible increases in blood O2 carrying capacity during hypoxia bouts, (iii) minimal recruitment of anaerobic metabolism during hypoxia bouts, and (iv) protection of tissues from oxidative damage despite alterations in the homeostasis of reactive oxygen species and cellular redox status. Of these features, (i) is unique to intermittent hypoxia, (ii) also occurs in fish exposed to acute hypoxia-reoxygenation, and (iii) and (iv) are observed in both fish acclimated to intermittent hypoxia as well as those acclimated to constant hypoxia. This is the most extensive investigation to date on how fish cope with the energetic and oxidative stress challenges of intermittent hypoxia, and how these responses differ from constant hypoxia. This thesis adds substantial insight into the general mechanisms by which animals can respond to an ecologically important but poorly understood feature of the aquatic environment. / Dissertation / Doctor of Philosophy (PhD) / Oxygen levels in the aquatic environment are dynamic. Many fishes routinely encounter changes in oxygen content in their environment. However, we have very little understanding of how cycles between periods of low oxygen (hypoxia) and periods of high oxygen (normoxia) affect the physiology of fish. This thesis investigated how Fundulus killifish cope with daily cycles between hypoxia and normoxia (intermittent hypoxia) by modifying oxygen transport, metabolism, and oxidative stress defense systems. I found that killifish rely on a unique and effective physiological strategy to cope with intermittent hypoxia, and that this strategy is distinct from how they respond to a single bout of hypoxia (followed by normoxia) and to a constant pattern of only hypoxia. This is the most extensive investigation to date on how fish respond to the challenges of intermittent hypoxia, an understudied but ecologically important type of aquatic hypoxia.

Cereal rye (CR), the most common and effective nitrogen (N) scavenging cover crop option in the Midwest, is often utilized in cropping systems to reduce nitrate loss for environmental benefits. To increase environmental efficiency in Midwest corn cropping systems, we must increase the overall adoption of CR. However, due to the yield reduction potential (6%) for corn planted after CR termination, CR is primarily recommended before soybean. To increase CR adoption, we must develop adaptive fertilizer management practices that achieve competitive grain yields relative to cropping systems where CR is not adopted. Therefore, the objectives of this study are to determine (1) the effect of CR and starter nitrogen rate on corn growth and nitrogen content. (2) the optimum starter nitrogen rate to achieve agronomic optimum corn yield following CR. (3) the impact of phosphorus (P) at starter on plant growth, nitrogen content, and yield with the inclusion of CR. For our study, five starter N rates were applied in a 5x5 cm band to both CR and non-CR plots, concentrations ranged from 0-84 kg N ha^-1in 28 kg N ha^-1 intervals. Total N applied was the same for each treatment, relative to its location, and was split between starter N at planting and sidedress applied at growth stage V6 relatively. Although CR termination took place at least two weeks before planting, CR decreased corn grain yield at one of three locations by an average of 8%, nitrogen recovery efficiency (NRE) by 27%, and R6 total N content by 23%, relative to the conventional control (non-CR 0N), when no starter N was applied. At one of three locations, starter N rates of 56 kg N ha^-1, 56 kg N ha^-1plus 17 kg P ha^-1, and 84 kg N ha^-1 increased corn grain yield, in CR plots, and 56 kg N ha^-1 plus 17 kg P ha^-1 increased corn grain yield in non-CR plots. Phosphorus increased corn grain N content at growth stage R6 in one of three locations and did not impact corn grain yield at all locations. We conclude that the inclusion of starter N at planting has the potential to increase agronomic productivity in CR corn cropping systems in soil environments with a high capacity to mineralize soil N. However, further research is required to refine our starter N results to find an optimum starter N rate to apply before planting corn following CR.

ARCHITECTURE The centre and entrance point for atrection a relx is terace with pool, with corridor to cafe and skylights that leads to reception. Around this atrium, there is a ramp, rising up. Pools are not see n ko the screens are individual attractions, atmosphere. The height change of each pool, sauna and whether this involves physical effort is rewarded with open views to the surroundings and relax themselves. Entering the building through a covered, but bright bay, passage is a continuation of the street fishing. Thus the very end of the reception side. Thus eliminate the problem of a parcel which is like a scene out of town. Layout In the passages suggest leaving the car park, Kafe-bar with a simple menu and fresh multifunctional workshop, creative playground. It is known fact, that in the old spa locations to find valuable pieces of pottery, small painting and sculpture and other artifacts that speak of links with the vivacious work, relax, relax with a manual and spiritual. This room will also serve as a nursery for parents resting in the spa, in the specified date and time. Upon entering the spa itself, the reception with high ceilings and skylights from the terrace, the visitor to the issue of changing rooms with bathroom facilities. Consequently, the choice whether to receive the attractions, or go down to the fitness center or gym. Another option is to move the spa itself. In the direction from the top down it is pliable dough, the blood will get the opposite route, in which the visitor shall issue a physical effort. 2np In addition to coffee for guests only and exit to the terrace, and massage booths are located. Much of the area occupied by the technical room, spa bath as well as administration. On the next floor guest vystkytne a larger foyer, drinking KURO room and swimming and first aid. Glass facades can be glanced only in forests of the Riviera, but the atrium, with an outdoor terrace and heated swimming pool at all times. Foyer is the actual beginning of the journey. The first ramp is rising just from my father. All the dark hallway, followed by a bright and translucent glass facades. The key is just a wall bordering the ramps and a few additional columns for the perimeter of the building. About half a meter above (and always rises only about 500 mm, the gradient of 1:16 to 8 meters length), the visitor gets to the first pool. Sunny southern facade is designed as a double, at this point is the greenhouse, it is no wonder that the first two pools are linked to breathing, inhalation, nature herbs. The hall (+7400) is glass mat glass sanitary unit consisting of two toilets, toilets for disabled people and installation bay. On one front wall of the shower. This element is repeated, the cabin is only 2.6 meters high (sv room is 3.65 meters), it was acting to hinder lightweight and transparent. On the left side counterclockwise overcomes next ramp stages. Pools are right to counter a výrivý. In this part of the facade facing the street catchment area, the intersection of fishing and of 8 m of pools have already seen the two interface Brno: Petrov and Špilberk. There is also a visitor gets to escape-connecting staircase. Possibility of shortening the path to the sauna is right here. The following pool of options in turn draws the double facade.
