Investigation of Factors Influencing Recombination Versus Disproportionation of Complex Radicals Formed by C-N Homolysis of Breslow Type Intermediates and Related Compounds
… be used to predict the favorable reaction. Breslow intermediates formed by deprotonation of thiazolium salts and reaction with aromatic aldehydes are examples of electron rich enamines. These breslow intermediates can undergo C-N bond homolysis to form a radical pair the either recombine or …

Bicyclische Triazoliumsalze als Präkatalysatoren in der asymmetrischen Benzoin- und Acyloinkondensation und asymmetrische Synthese von Oxazolidin-2-onen
… catalyst and on the steric hindrance in the Breslow intermediate. The asymmetric synthesis of cis-4,5-disubstituted oxazolidin-2-ones is described. Following a four step reaction sequence of alpha-alkylation, 1,2-addition with subsequent carbamate protection, cyclization and concluding with …

Die effek van inoefening op enkele koronêre risikofaktore en hulle onderlinge verwantskap by Suid-Afrikaanse bestuurslui
… family history of heart disease, the Belloc and Breslow-index, age and smoking. The other coronary risk factors showed better relationships with LDL-cholesterol, TC/HDLratio, HDL-cholesterol and total cholesterol and contributed 95.6%, 87.9%, 81.2% and 95.6% to their respective variances. With …

Validación de un modelo pronóstico para pacientes con enfermedades medicas no neoplásicas en estado avanzado en atención primaria: proyecto Paliar Primaria
… estadísticos de logaritmo del rango y el test de Breslow que son no significativos, siendo el valor de p igual a 0,615 y 0,572 respectivamente. A los 12 meses de seguimiento, la probabilidad de mortalidad pronosticada por cuartiles de riesgo osciló entre 12,52% el de más bajo riesgo y 41,28% en el …

Narratives of Directors of Disability Services: Forms of Social Capital in Practice
This qualitative case study examines the journeys of four directors of disability services. The voices of disability service providers in higher education remain relatively silent in the extant literature. Therefore, this research focused on: (1) What are the participants’ journeys into becoming …

On semiparametric regression and data mining
… penalised quasi-likelihood (PQL) approximations (Breslow & Clayton, 1993) but variational approximations. Originating in physics, variational approximations are a relatively new class of approximations (to statistics) which are simple, fast, flexible and effective. They have recently been applied …

Pregnancy outcomes in females with hidradenitis suppurativa
… measures were compared using Chi-square and Breslow-Day. No evidence suggested the rates observed in the datamart were substantially different from national figures. Thus, providing a degree of validity to the data. During construction of the datamart, several data quality problems were …

Clinico-morphological Characteristics, Histological Typification and Their Correlation with Some Molecular Markers in Cutaneous Melanoma // Клинико-морфологични характеристики, хистотипизация и корелацията им с някои молекулярни маркери при кожен меланом
… дебелината на лезията в милиметри по скалата на Breslow с цел установяване на зависимост, която да обуслови прогресията на лезията. На базата на проведеното от нас изследване изработихме диагностичен алгоритъм за доуточняване поведението при кожен меланом. Предиктивността на анти-BRAF антитяло …

Fatty Acids as a Potential Foraging Cue in Bumblebee Pollen Detection
Bee populations, both wild and commercially supplied, are on the decline. A diminishing availability of required nutritional components may be a major contributing factor. Understanding how bees are able to both detect and remember the locations of these dietary macromolecules will be a valuable …

Development of soil lead and tree-ring methods for characterizing atmospheric deposition gradients and subsequent tree growth responses
Atmospheric deposition of pollutants and nutrients can have a range of effects on aquatic and terrestrial ecosystems. Despite its ecological importance, it remains a challenge to model patterns of deposition across complex terrain and also to assess how forest ecosystems are reacting to chronic …

The spatial organization of culture, economics and politics: The architecture and political economy of Fordism and global Fordism
Cultural Studies has developed a coherent set of analytical methods and political assumptions which are articulated to one another at the site of the text. The author disputes this articulation, arguing that in both method as well as assumption Cultural Studies duplicates early-modern political …

Advances in Survival Analysis: Accurate Partial Likelihood Computation by Poisson-Binomial Distributions and Nonparametric Competing Risk Cox Model
Two novel contributions to survival analysis are presented. The first project revisits the partial likelihood in the Cox model, which traditionally approximates conditional probabilities using risk score ratios under a continuous-time assumption. We propose a new accurate partial likelihood …
