Abstract:
Abstract Background The SpeedWheel (SW) test is an objective test of visual acuity (VA) using suppression of the optokinetic nystagmus (OKN). Here, we established prediction intervals of the SW measures compared to Snellen acuity in adults and children. Subjects and Methods In this prospective, single center study, subjects aged at least 4 years underwent testing of VA with SW, Landolt-C, and Tumbling-E symbols (Freiburg acuity test: FrACT-C, FrACT-E). Prediction intervals were established for SW compared to FrACT-C or -E and for FrACT-E compared to FrACT-C. Mixed linear effect models were applied for statistical analysis. Results From 241 subjects, 471 eyes were included: median age 36 years, range 4 – 88 years, 43.6% male, 56.4% female. Eyes included were either healthy or had various underlying ophthalmic conditions. Prediction intervals for SW to estimate FrACT-C or -E acuity showed a similar range compared to the prediction interval of FrACT-C for the estimation of FrACT-E acuity. For each acuity step, there was no influence of age. Up to an SW acuity of 0.7 logMAR, 80% of the subjects had a FrACT-C acuity that was at most 1.6 logMAR lines below, and for an SW acuity of 1.0 logMAR, FrACT-C acuity was not worse than 4 logMAR lines. Prediction intervals for eyes with refractive error, cataract, visual field loss and retinal disease did not differ significantly from healthy eyes in contrast to eyes with amblyopia or multiple ophthalmic disorders. SW correlated well to FrACT tests and results of a previous study fell within our prediction estimates. Conclusion Our prediction intervals for SW acuity may be used to estimate Snellen acuity (FrACT-C and -E) in the clinic in adults and children unable to cooperate in other acuity testing.

Abstract:
We analyse in this paper the way randomness is considered and used in ArtiE-Fract. ArtiE-Fract is an interactive software, that allows the user (artist or designer) to explore the space of fractal 2D shapes with help of an interactive genetic programming scheme. The basic components of ArtiE-Fract are first described, then we focus on its use by two artists, illustrated by samples of their works. These "real life" tests have led us to implement additional components in the software. It seems obvious for the people who use ArtiE-Fract that this system is a versatile tool for creation, especially regarding the specific use of controlled random components.

Abstract:
Abstract A one-dimensional fractional one-phase Stefan problem with a temperature boundary condition at the fixed face is considered by using the Riemann–Liouville derivative. This formulation is more convenient than the one given in Roscani and Santillan (Fract. Calc. Appl. Anal., 16, No 4 (2013), 802–815) and Tarzia and Ceretani (Fract. Calc. Appl. Anal., 20, No 2 (2017), 399–421), because it allows us to work with Green’s identities (which does not apply when Caputo derivatives are considered). As a main result, an integral relationship between the temperature and the free boundary is obtained which is equivalent to the fractional Stefan condition. Moreover, an exact solution of similarity type expressed in terms of Wright functions is also given.

Abstract:
AimsTo evaluate contrast sensitivity (CS) in patients with advanced glaucomatous visual field damage, and to compare two clinical CS tests.MethodsThis was a cross-sectional test–retest study. Twenty-eight patients with open-angle glaucoma, visual acuity (VA) better than 20/40 and visual field mean deviation (MD) worse than −15 dB were enrolled. Patients underwent VA, visual field and CS testing with the Pelli-Robson (PR) chart and the Freiburg Visual Acuity and Contrast Test (FrACT). Retest measurements were obtained within 1 week to 1 month.ResultsMedian (IQR) age and MD were 61.5 (55.5 to 69.2) years and −27.7 (−29.7 to −22.7) dB, respectively. Median (IQR) VA was 0.08 logarithm minimum angle of resolution (0.02 to 0.16), corresponding to 20/25 (20/20 to 20/30). Median (IQR) CS was 1.35 (1.11 to 1.51) log units with the PR chart and 1.39 (1.24 to 1.64) log units with FrACT. VA explained less than 40% of the variance in CS (adjusted R2=0.36). CS estimates of both tests were closely related (rho=0.88, p=0.001), but CS was 0.09 log units higher with FrACT compared with the PR chart, and the 95% repeatability intervals (Bland-Altman) were 46% tighter with the PR chart.ConclusionsDespite near-normal VA, almost all patients showed moderate to profound deficits in CS. CS measurement provides additional information on central visual function in patients with advanced glaucoma.

Abstract:
La description du comportement du béton sous chargements dynamiques (explosions, collisions, séismes…) fait actuellement l’objet de nombreux travaux de recherches. Bien que la modélisation reste complexe pour ce matériau à cause de la présence simultanée de plusieurs phénomènes (l’endommagement, les effets d’inertie et de viscosité, la fissuration…), un bon nombre d’approches ont été proposé en associant ces phénomènes (endommagement (Pedersen et al., Eng. Fract. Mech. 75, 3782 (2008) [1]), viscosité (Bazant et al., J. Eng. Mech. ASCE 126(9), 971 (2000a); Bazant et al., J. Eng. Mech. ASCE 126(9), 962 (2000b) [2,3])…, effet d’inertie (Reinhardt & Weerheijm, Int. J. Fract. 51, 31 (1991) [4])). Avec une loi d’endommagement, ce travail formule une description du comportement dynamique du béton en traction et en compression. Fondée sur des concepts physiques (la rigidité non linéaire endommageable associée à la déformation, la viscosité, l’inertie associée à l’accélération et la rupture par résonance), cette loi décrit l’évolution de ces différents effets intervenants lors d’un chargement dynamique du matériau. Enfin, sous la lumière des résultats, l’article propose une interprétation physique à la rupture par écaillage qui apparaît dans le béton surtout sous des charges impulsionnelles en traction (un plan de rupture droit, qui passe parfois à travers les granulats).

Abstract:
Major transportation and land use problems are experienced in the Menlyn precinct in Tshwane. Current infrastructure allows motor vehicles to dominate public transport and pedestrian thoroughfare. Pedestrians and motor vehicles are placed in danger and traffic problems occur when taxis and buses make use of road lanes and sidewalks to stop. The interaction and superposition of these problems are manifested as a fracture in the urban framework, disconnecting people, environments and different transport modes from one another and the rest of Tshwane. The aim of this design proposal is to address the fractured experience in the Menlyn area. The project should respond to the poor connectivity and transport problems currently experienced in Menlyn and reinforce Menlyn as an important node within Tshwane. It is argued that a Platform Building at Menlyn could integrate the various transport systems present in the Menlyn precinct with the envisioned underground Gautrain station.

Neste trabalho, foram avaliados aspectos diversos da emissão de CO2 (FCO2) em um Latossolo Vermelho em áreas de cana-de-açúcar sobre os sistemas de manejo de cana queimada (CQ) e cana crua (CC), no nordeste do Estado de São Paulo. No experimento 1 (ano de 2007), a média da FCO2 foi 39% superior na área de CQ (2,87 μmol m-2 s-1) quando compara à CC (2,06 μmol m-2 s-1) ao longo de um período de 70 dias de avaliação. Os modelos ajustados aos semivariogramas experimentais de FCO2 foram, na sua maioria, exponenciais em ambas as áreas. Os mapas de emissão foram homogêneos após um período de seca. O teor de matéria orgânica do solo e o estoque de carbono do solo (0-0,25 m) foram 13 e 20%, respectivamente, superiores em CQ quando comparados à CC. O grau de humificação da matéria orgânica do solo e a sua interação com a densidade do solo foi um importante fator, não somente na diferenciação da emissão de CO2 entre os diferentes sistemas de manejo. No experimento 2 (ano de 2008), foi conduzida a caracterização anisotrópica das variáveis estudadas por meio da dimensão fractal (DF), para diferentes direções (0o, 45o, 90o e 135o) em relação às linhas de plantio (0o). A propriedade porosidade livre de água (PLA) foi um dos principais fatores relacionados à variabilidade espacial de FCO2, independentemente das direções. Os valores de DF foram significativamente inferiores no sentido de plantio da cultura da cana-de-açúcar, indicando, além de anisotropia dessa propriedade, maior homogeneidade de FCO2 na direção de 0o. A PLA mostrou ser uma importante propriedade na compreensão da variabilidade espaçotemporal de FCO2, especialmente nas áreas de cana queimada
In this work was studied various aspects of soil CO2 emission (FCO2) of a bare Dark Red Latosol in sugarcane areas submitted to burned (B) and green (G) management systems in northeastern of São Paulo State.

FCO2 Semivariogram models were mostly exponential in both areas. The emission maps are clearly more homogeneous after a drought period in both sites. Organic matter content and carbon stock (0-25 cm) were 13% and 20% higher in B, respectively, when compared to G. Regression analysis indicates that the humification index of soil organic matter, and its interaction with soil bulk density, is an important factor not just to differentiate emissions in each plot. In the experiment 2 (2008) the anisotropic characterization of the studied variables, was performed by deriving the fractal dimension (DF) calculated for different directions (0o, 45o, 90o and 135o) in relation to the crop line (0o). The air-filled pore space (AFPS) was the main factor affecting the spatial variability of FCO2 in all directions. The FCO2 DF values were significantly lower in the direction of planting of sugarcane crop, indicating anisotropy of this property and greater homogeneity in this direction. The AFPS was an important property in understanding the spatiotemporal variability of FCO2, especially in the areas submitted to burn

Full text
Abstract:
This thesis, a social novel in the tradition of Tom Wolfe's The Bonfire of the Vanities and Michael Chabon's The Amazing Adventures of Kavalier and Clay, is all at once an attentive first-person study of a twenty-something man close to his cracking point in his first post-college job, a detailed exposé of national fraternities, and the sweeping panoramic view of an entire generation of over-programmed college students searching for direction. Frat Star follows a fragile college graduate named Charles Washington, who takes a position as an "Educational Consultant" with a national fraternity in his first semester after graduation. For sixteen straight weeks, he drives across the country, from college to college and fraternity house to fraternity house, meeting with alumni and students, and living on frat house couches and in seedy off-exit hotels. As he travels, the pressure mounts for Charles to convince his family and friends back home that this is a "Real Job" and that his work actually matters to the business world, but at each new fraternity house he visits, his yearning for the old college atmosphere grows--the beer, the parties, the girls!--threatening to send him into a frightening tailspin. How can he be a professional when the temptations of youth still seem so attractive? And before Charles can sort out what is happening in his own life, he finds himself stuck in a vicious tug-of-war between students, alumni, administrators, and the national fraternity, when he must deal with one particularly abrasive undergraduate fraternity and the aftermath of its disastrous decisions. Spanning thousands of miles, from Florida to California, from Illinois to New Mexico, this thesis takes us inside fraternity houses, into their attics and their basements, behind the scenes of their rituals and ceremonies, inside their parties, inside their heads, giving us a view not only of the power of the national fraternity, but the disconnect between alumnus and student, between Baby Boomer and Generation X and Millennial. Incorporating research as varied as the generational studies of Howe and Strauss, and Alexandra Robbins' psychological study of the "Quarterlife Crisis," Frat Star stretches across the country, stretches across genre, stretches from text to illustration, but is ultimately the human story of a young man's longing for morality, independence, and purpose in a world he simply has not been prepared to understand.

Abstract:
Don't Frack With Denton chronicles the ground-breaking movement to ban hydraulic fracturing in the city of Denton, Texas by combining observational location shooting with extensive sit-down interviews and carefully negotiated subject-filmmaker relationships to create a safe and comfortable space for thoughtful reflection and criticism of a complex social movement who's activities span several years and many individuals. The result is a long-form documentary that is unapologetically in solidarity with this movement's goals while simultaneously maintaining enough editorial independence and critical distance to allow the activists themselves to honestly evaluate their decision-making, tactics and interpersonal relationships in ways that will provide insight and instruction to similar movements around the country and the world.

Nessa tese estudamos alguns aspectos da comutatividade fraca entre grupos nilpotentes isomorfos, onde a comutatividade é determinada por isomorfismos ou mais geralmente por bijeções entre esses grupos. O conceito é de comutatividade fraca foi introduzido por Sidki em 1980 [1]. Nesse trabalho foi definido o Grupo de Comutatividade Fraca gerado por duas cópias isomorfas de um grupo H, [equação] onde [equação] um isomorfismo entre H e H. Seguindo um ponto de vista combinatório elementar analisamos nessa tese a estrutura do grupo [equação] onde H é uma cópia isomorfa de H é uma bijeção de H para H tal que [fórmula matemática] é um p-grupo finito, com ênfase no caso um p-grupo abeliano elementar. _________________________________________________________________________________ ABSTRACT
In this thesis we study some aspects of the weak commutativity between isomorphic nilpotent groups, where the commutativity is defined by isomorphisms or more generally by bijections between such groups. The concept of weak commutativity was introduced by Sidki in 1980 [1]. In this work was defined the Weak Commutativity Group generated by two isomorphic copies of a group H, [equation] where [equation] a isomorphism between H and H. Following an elementary combinatorial point of view we analyze in this thesis the structure of the group [equation] where H is an isomorphic copy of H is a bijection from H to H such that [mathematical formula] is a finite p-group with emphasis in the case where H is elementary abelian p-group.

Entre os povos ameríndios a alimentação articula-se intimamente com suas concepções sobre corpo, influenciando-o diretamente. Entre os Kaingáng, a fabricação dos corpos articula-se com a mudança ocorrida na alimentação entre o "tempo dos antigos" e hoje. De acordo com a rede semântica nativa, a "comida antiga" era mais "forte" que a atual, bem como o corpo das pessoas que dela comiam. A nova comida, do "branco", considerada "fraca", estaria construindo corpos também "fracos" e mais suscetíveis à doenças entre os jovens. São abordados ainda festas, jogos, visitas e outros modos de compartilhamento de comida. Esses eventos serão analisados à luz da cosmologia Kaingáng, a fim de entender a lógica da generosidade e as diversas trocas operadas nesses contextos, seja entre homens ou entre homens e deuses. Essas práticas são compreendidas como práticas de auto-atenção à saúde do grupo um como todo, tendo em vista que fortalecem todo o corpo social, além de valorizarem a distribuição e produção de "comida forte", considerada saudável pelos Kaingáng.
This study seeks to understand alimentary practices of the Kaingáng of the Xapecó Indian Reservation from an anthropological perspective that considers its practical and symbolic aspects. Among Amerindian peoples, food is closely tied to their views on the body, influencing it directly. Among the Kaingáng these bodily aspects are articulated with changes in alimentation between the "time of the elders" and today. According to the native semantic network, "ancient food" is "stronger" than that which has been introduced with contact, as well as the bodies that consumed it. The new food, "white" food, is considered "weak", and it is producing the weak" bodies of the youth, making them more susceptible to illness. Festivities, games, visiting and other occasions that involved the sharing food were studied. These events were analyzed in the light of Kaingáng cosmology, in order to understand the logic of generosity and the various exchanges performed in these contexts, be they between humans or between humans and gods. These practices are also considered to be health practices for the group as a whole, since they strengthen the social body, and value the distribution and production of the "strong food" considered healthy by the Kaingáng.

Abstract:
I takt med att världshandeln ökar så ökar även transporterna. Med hjälp av internet har det blivit enklare än någonsin att beställa en vara som skickas från andra sidan jordklotet. Detta arbete har undersökt i vilken utsträckning konsumenter reflekterar över vilka effekter deras beställningsvanor vid varubeställningar får för miljön och hur intresserade de är av att värna om miljön genom att beställa varor med hjälp av en dyrare och mer miljövänlig frakt. Detta har gjorts genom intervjuer med fyra konsumenter i varierande åldrar där det undersökts vad deras inställning är till en dyrare och miljövänligare frakt, hur mycket mer de skulle vilja betala för en sådan frakt samt även vad de vet om det miljöarbete som bedrivs inom sjöfart. Resultatet visar att det finns ett intresse att betala ett högre pris för en mer miljövänlig frakt om priset är överkomligt och om det finns ett förtroende för den som erbjuder den miljövänligare frakten. Viljan skiljer sig mellan de olika respondent och är beroende på vad det är för typ av vara och vad den ordinarie frakten kostar. Respondenterna visar också begränsad kunskap inom sjöfart och det miljöarbete som görs inom branschen.
The world trade is increasing rapidly and so is the amount of transportation. With help of the internet it is now easier than ever to order a product which will be sent from the other side of the world. This study aims to investigate to which extent consumers consider what effects their behaviour will have on the environment and how interested they are in protecting the environment when ordering products by paying a higher price for a more environmentally friendly transport. This is done by conducting four interviews with customers of different age and asking questions about their attitudes towards a more expensive and environment friendly transport. More specifically, questions were asked about how much more they would be willing to pay for that kind of transport. Furthermore, questions were asked about what they know about the work that is being done and has been done to reduce the effects on the environment caused by shipping. The result shows that they are willing to pay a higher price for a more environmentally friendly transport. For this to be possible the price needs to be affordable and they need to have a trust in the company offering this kind of transport. There are differences among the interviewed persons in how much they are willing to pay depending on what product they are buying and what the cost is for the original transport cost. This study also shows that the respondents have a very limited knowledge about the work that is being done and has been done to benefit the environment within the shipping business.

Abstract:
Abstract Tight gas/tight oil reservoirs require fracture stimulation to achieve commercial rates of hydrocarbons. Fracturing operations involve pumping considerable volumes of proppant and water/gel into the reservoir. Rapid cleanup of fracturing fluids and residual proppant ensures the desired goals of the stimulation operations are achieved: enhancing the flow capacity of the well while minimizing the risk of proppant damage to surface equipment. It is normal for significant quantities of proppant and frac fluid to flow back after opening the well for cleanup. Frac fluid often contains broken cross-linked gel, which must be flowed back to ensure cleanup of the fracture and minimize plugging of the fracture face and the proppant pack. In North America, it is not unusual for frac fluid recovery to be only a small fraction of the amount of injected fluid. Frac fluid recovery of 5 to 30 percent is not unusual and 50 percent is often considered excellent. In the Sultanate of Oman, BP is currently achieving 50 to 90 percent frac fluid recovery, while pressure transient analysis indicates post-frac skin damage figures of -6 or better, indicating excellent stimulation effectiveness. Critically, no proppant has flowed through to the surface facility. These cleanup procedures have been conducted in wells with a variety of frac types including 450,000 to 1,000,000 lb cross-linked gel fracs and multiple 17,000 bbl slick water fracs. An analysis of the procedures used to achieve these results will be presented in this paper. It indicates that allowing the frac to close and opening the well on a moderate choke, with re-direction of the post-frac fluid through effective sand management systems, followed by flowing the well at a managed drawdown against the reservoir has achieved excellent results. These results underpinned the decision to move forward in this multi-billion dollar development project.

Abstract:
Abstract In the past decades, most oil explotation in the White Tiger oil field was produced from the basement reservoir. However, in recent years, these pay zones consist of basement reservoirs, Oligocene reservoirs, and Miocene reservoirs of which oil field s have been declined in oil production rate due to several issues such as complex fracture network, high heterogeneity formation, high water cut, and the reduction of reservoir pressure. The huge issues in the most production wells at basement reservoir were high water cut and it has been significantly increasing during oil production yearly. Therefore, the total amount of oil production in all pay zones sharply decreased with time. At present, the lower Miocene reservoir is one of the best tight oil reservoirs to produce oil extractrion. The lower Miocene reservoir has been faced some issues such as high heterogeneity, complex structure, catastrophic clay swelling, low connectivity among the fractures, low effective wellbore radius and the reservoir that is hig h temperature up to 120°C, the closure pressure up to 6680psi, reservoir pressure up to 4500 psi, reservoir depth up to 3000m. Another reason low conductivity consists of both low reservoir porosity ranging from 1% of the hard shale to 10% of the sandstone formation, and the low permeability raining from 1md to 10md. By considering the various recovery methods, the integrated hydraulic fracturing stimulation is the best tool to successfully stimulate this reservoir, which method allows an increase in oil production rate. In the post fractured well has been shown an increase in productivity over 3 folds in comparison with the base case with fracture half-length nearly 75m, and fracture conductivity about 5400md.ft, which production rate is higher than the production rate of the base case. In addition, the proppant mass is used of 133,067 lbs of which the first main stage is to pump sinter lite bauxite proppant type of 20/40 into the fractures and the next big stage is to pump sintered ball bauxite proppant size of 16/30 into the fractures, which not only isolate proppant flow back but also increase fracture conductivity at the near wellbore as wel as high productivity rate after fractured well. To improve proppant transport, fract uring fluid systems consist of Guar polymer concentration of 11.2 pptg with these additives to form a total leak-off coefficient of 0.00227 ft/min0.5.
