The Nameless : a novel

Drakos, Aleksander January 2018 (has links)
An economically depressed United States is thrown into civil chaos over conflicts between protest groups and a militarised police force. Caleb Dumas, via an encounter with his neighbour, Carys, learns that he is a hybrid of human and Tskiri, a humanoid species with telepathic and thermokinetic abilities. Caleb and his family get separated during a riot, and he, along with his twin brother, Ben, is arrested and sent to a penal work camp. Meanwhile, as modern society begins to break down, the Askala - a species of vampiric humanoids who live underground - begin attacking humans once more as the elements which kept them underground begin to falter. Six years later, Ben is killed, and Caleb injured, in an altercation over food. Caleb is then rescued by Jasha, one of the Askala, who takes him to the nearby Farm, where Jasha's family raises humans for their blood. Unbeknownst to Caleb, however, the Farmers have recently attempted a revolt against the Askala, which results in a retaliatory attack by the Askala, during which Caleb intervenes. As he communicates with Roan, the leader of the attack party, Caleb learns that the Askala and the Tskiri are two halves of the same thing. Caleb accidentally kills Roan with his thermokinetic ability, which only heightens the tension between the Farmers and the Askala. Carys returns, having tracked Caleb to the Farm through their shared connection, and together the two of them challenge Father, the leader of the Askala for power over the Farm. The Askala Father nearly kills Caleb, but ultimately, he and Carys triumph, placing the responsibility for both the Farm and the Askala compound entirely in Caleb's hands.

Compounding in Malay : a descriptive analysis

Azam, Yasir January 2016 (has links)
This study concerns Malay compounding. The aim is to have an in-depth description and analysis of the topic which will create a more comprehensive and systematic understanding of the phenomenon in the language. Various features and issues in relation to compounding are identified and explored in order to achieve this aim. Given that Malay compounds and phrases are structurally similar, the question of whether compounding is a morphological or syntactical product is first entertained. Discussion on this issue favours the understanding that compounds can be distinct objects from those of structurally identical phrasal ones in Malay language. The focus is then given on the topics of definition, components, headedness, criteria and classification of compounds as the foundations of Malay compoundhood. It is agreed that Malay can have left, right and headless compounds, with the prototypical structures of [X Y] (X)(Y) for endocentric and [X Y] (Z) for exocentric compounds. It is also agreed that the measures for Malay compounds (with degrees of suitability) are the syntactical criteria (inseparability, modification, component switching, circumfixation and reduplication), phonological criteria (stress and assimilation), and semantic criteria (compositional/lexicalised status) of compoundhood. This study also supports the classification of Malay compounds base on the relationship between their components, i.e. under the subordinative, attributive or coordinative relationships. Based on these foundations, this study is able to analyse and organize the different types of compounds available from the corpus, among others the (NN, NV, NA) nominal compounds, the (VN, VV, VA) verbal compounds, the (AN, AA) adjectival compounds and the idiomatic compounds. In general, the attributive relationship has the most common occurrence throughout the analysis, followed by the coordinative ones, and finally the extremely limited subordinative relationship. The discussions and findings of this study have definitely enhanced the overall knowledge on Malay compounding.

Investigating classroom dynamics in Japanese university EFL classrooms

Matsumoto, Yasuyo January 2009 (has links)
Since 1868 to the present day, the Ministry of Education, Sports, Science and Culture (MEXT) has implemented many reforms to enhance English education in Japanese universities. However, much still remains to be done to improve the situation and one of the biggest hurdles is the fact that there are many unmotivated students in Japanese university EFL classrooms. This thesis explores the reasons for this problem by focusing on inter- and intra-relations between teachers and students in this context. Data were collected through classroom observations, interviews and questionnaires. The study employs both qualitative and quantitative research methodologies and uses space and methodological triangulation in order to overcome parochialism. My conclusions are that: 1) Visible and invisible inter-member relations exist between members of university classes and their teachers; 2) The teacher's behaviour affects the students' behaviour and impacts on their learning; and 3) Cooperative learning has a positive influence on language acquisition; 4) Japanese university students may not perceive how little interaction they have with their teacher; 5) Students exhibit gender differences in terms of the types of problems encountered and the ways in which they deal with them, but some problems are dealt with negatively by female and male students alike; and 6) Teachers appear not to perceive the problems and when they do they often deal with them by using negative strategies.

Characterizing the Fate and Mobility of Phosphorus in Utah Lake Sediments

Randall, Matthew Chambers 01 August 2017 (has links)
An increasing number of lakes worldwide are impacted by eutrophication and harmful algal blooms due to nutrient inputs. Utah Lake is a unique eutrophic freshwater lake that is naturally shallow, turbid, and alkaline with high dissolved oxygen levels. Recently, the Utah Division of Water Quality has proposed a new limitation of phosphorus (P) loading to Utah Lake from wastewater treatment plants in an effort to mitigate eutrophication. However, reducing external P loads may not lead to immediate improvements in water quality due to the legacy pool of nutrients in lake sediments. The purpose of this study was to characterize the fate and mobility of P in Utah Lake sediments to better understand P cycling in this unique system. We analyzed P speciation, mineralogy, and binding capacity in lake sediment samples collected from 15 locations across Utah Lake. P concentrations in sediment ranged from 306 to 1894 ppm, with highest concentrations in Provo Bay near the major metropolitan area. Sequential leach tests indicate that ~25-50% of P is associated with Ca (CaCO3/ Ca10(PO4)6(OH,F,Cl)2 ≈ P) and 40-60% is associated with Fe (Fe(OOH) ≈ P). Ca-associated P was confirmed by SEM images, which showed the highest P concentrations correlating with Ca (carbonate minerals/apatite). The Ca-associated P fraction is likely immobile, but the Fe-bound P is potentially bioavailable under changing redox conditions. Batch sorption results indicate that lake sediments have a high capacity to absorb and remove P from the water column, with an average uptake of 70-96% removal over the range of 1-10 mg/L P. Mineral precipitation and sorption to bottom sediments is an efficient removal mechanism of P in Utah Lake, but a significant portion of P may be temporarily available for resuspension and cycling in surface waters. Mitigating lake eutrophication is a complex problem that goes beyond decreasing external nutrient loads to the water body and requires a better understanding in-lake P cycling.

Experimental study of the aromatics production from the pyrolysis of scrap tire rubber using heteropolyacids-based catalysts / Étude expérimentale de la production d'aromatiques par la pyrolyse des pneus de caoutchouc en utilisant des catalyseurs à base d'hétéropolyacides

Tavera Ruiz, Claudia Patricia 13 October 2017 (has links)
Les pneus de caoutchouc usagés sont l'une des plus grandes productions annuelles de déchets dans le monde entier. Ceci est dû à leur composition non biodégradable, leur durée de vie et leur traitement difficile, ce qui provoque des problèmes environnementaux et de santé publique, en raison de son accumulation et de la mise en œuvre de techniques de traitement inappropriées. En tenant compte de ce problème, il est envisageable de chercher à valoriser ces déchets grâce à des procédés comme la pyrolyse. L'objectif principal de ce travail était d'évaluer expérimentalement la pyrolyse de pneus du caoutchouc (STR) dans le but de produire des composés aromatiques monocycliques. Pour cela, une étude expérimentale de pyrolyse de STR sans catalyseur a été réalisée et les conditions les plus favorables de température et de débit d'azote ont été déterminées. La transformation du D,L limonène présent dans l’huile en aromatiques en utilisant différentes combinaisons hétéropolyacide/support ont été évaluées, afin de sélectionner les plus sélectives vers les aromatiques. Les résultats ont montré une conversion du limonène en p-cymène, monoterpènes et menthènes, et on a constaté que la production de p-cymène est promu par l'acidité de Lewis. Depuis, les catalyseurs étant plus sélectifs dans la transformation du limonène, ont été validés dans la pyrolyse de STR. Les résultats montrent que le rendement en aromatiques a augmenté (de 8,05%) à un maximum de 15,06 %p et la concentration a abouti environ 37%, en utilisant un catalyseur à base de molybdène dans lequel les sites d'acide de Lewis sont les prédominants. / Scrap tire are waste that produces one of the largest annual production all over the world. Because its non-biodegradable composition, its end of life and treatment is difficult, causing environmental and public health problems, due to the accumulation and implementation of inappropriate treatment techniques. Based on this problem it is conceivable to seek to valorise these wastes through processes such as pyrolysis. The main objective of this work was to evaluate experimentally the pyrolysis of scrap tire rubber (STR) in order to improve single ring aromatic compounds, which have a higher industrial value in the oil of STR pyrolysis. To this end, an experimental study of pyrolysis of STR without catalyst was carried out and the most favorable temperature and nitrogen conditions were determined. The transformation of D, L limonene present in the oil into aromatics using different heteropolyacid / carrier combinations was evaluated, in order to select the most selective towards the aromatics. The results showed a conversion of limonene to p-cymene, monoterpenes and menthenes, and it was found that the production of p-cymene was promoted by Lewis acidity. Since the catalysts are more selective in the transformation of limonene, have been validated in the pyrolysis of STR. The results show that the yield of aromatics has increased (from 8.05%) to a maximum of 15.06% p and the concentration about 37%p, using a molybdenum catalyst in which the acid sites of Lewis are the predominant.

P-adiska tal

Eklund, Per January 2007 (has links)
<p>De p-adiska talen vars främsta användningsområde ligger inom talteorin beskrevs först av den tyske matematikern Kurt Hensel 1897.</p><p>För varje primtal p, så utvidgas talsystemet Q av rationella tal till ett större talsystem som betecknas Qp, de så kallade p-adiska talen.</p><p>En annorlunda valuation av rationella tal ger ett så kallat icke-arkimediskt absolutbelopp samt en annan metrik än den vi är vana vid, en ultrametrik. Vilket gör att kroppen av p-adiska tal Qp får en annorlunda topologi.</p><p>Ett icke-arkimediskt absolutbelopp har samma egenskaper som ett vanligt arkimediskt absolutbelopp, samt en extra egenskap nämligen .</p><p>Avslutningsvis använder vi oss av Hensels lemma, vilken bygger på Newton-Raphsons metoden för att lösa ekvationer, för att bestämma om ett polynom har rötter i Zp och i så fall vilka de är. Då den p-adiska analysen på många sätt är lättare än den reella analysen så visar Hensels lemma ganska lätt om ett polynomen har rötter i Zp.</p>

Solving Multiple Classes of Problems in Parallel with MATLAB*P

Choy, Ron, Edelman, Alan 01 1900 (has links)
MATLAB [7] is one of the most widely used mathematical computing environments in technical computing. It is an interactive environment that provides high performance computational routines and an easy-to-use, C-like scripting language. Mathworks, the company that develops MATLAB, currently does not provide a version of MATLAB that can utilize parallel computing [9]. This has led to academic and commercial efforts outside Mathworks to build a parallel MATLAB, using a variety of approaches. MATLAB*P is a parallel MATLAB that focus on enhancing productivity by providing an easy to use parallel computing tool. Using syntaxes identical to regular MATLAB, it can be used to solve large scale algebraic problems as well as multiple small problems in parallel. This paper describes how the innovative combination of ’*p mode’ and ’MultiMATLAB/MultiOctave mode’ in MATLAB*P can be used to solve a large range of real world problems. / Singapore-MIT Alliance (SMA)
