q-Karamata functions and second order q-difference equations

In this paper we introduce and study $q$-rapidly varying functions on the lattice $q^{N_0}:=\{q^k:k\in N_0\}$, $q>1$, which naturally extend the recently established concept of $q$-regularly varying functions. These types of functions together form the class of the so-called $q$-Karamata functions. The theory of $q$-Karamata functions is then applied to half-linear $q$-difference equations to get information about asymptotic behavior of nonoscillatory solutions. The obtained results can be seen as $q$-versions of the existing ones in the linear and half-linear differential equation case. However two important aspects need to be emphasized. First, a new method of the proof is presented. This method is designed just for the $q$-calculus case and turns out to be an elegant and powerful tool also for the examination of the asymptotic behavior to many other $q$-difference equations, which then may serve to predict how their (trickily detectable) continuous counterparts look like. Second, our results show that $q^{N_0}$ is a very natural setting for the theory of $q$-rapidly and $q$-regularly varying functions and its applications, and reveal some interesting phenomena, which are not known from the continuous theory

Neoplasmas em suínos: 37 casos

Resumo: Neoplasmas em suínos são raros. Esse trabalho descreve os neoplasmas encontrados em suínos na rotina diagnóstica de um laboratório de patologia veterinária localizado na Região Central do Rio Grande do Sul. Durante um período de 49 anos, 2.266 casos de várias afecções em suínos foram encontrados, dos quais 37 (1,6%) eram neoplasmas. Em ordem decrescente de frequência, os seguintes neoplasmas foram encontrados: Linfoma (11/37), nefroblastoma (11/37), melanoma (8/37) e papiloma (2/37). Adicionalmente, um caso de cada um dos seguintes tumores foi observado: Adenoma hepatocelular, carcinoma hepatocelular, colangiocarcinoma, histiocitoma fibroso maligno e sarcoma granulocítico. O aspecto macroscópico e histológico desses tumores é descrito e a sua epidemiologia é comparada com os dados disponíveis na literatura para neoplasia suína

Porovnání provozně ekonomických parametrů vybraných skupin tahačů návěsů

The aim of this diploma thesis is to find and evaluate decisive operational and economic indicators in a statistically significant group of trucks. They have a high level of chance and are therefore very difficult to determine in advance. These operating and economic indicators included repair and maintenance costs obtained from invoices, financial statements and the results of transport companies' operations. These costs were monitored for the time of operation of these trucks

Pedagogické role ve školní třídě

The final thesis deals with the topic of Pedagogical role in the school classroom. The aim of the thesis is to compare the pedagogical roles in schools of a regular type and in schools established according to § 16 article 9 of the education act. In the theoretical part, therefore, it defines the individual professions that occur in the school environment. It also describes their competences, job description and mutual status. The practical part subsequently puts this knowledge in context with knowledge based on experience from schools established according to §16 article 9 of the Education Act. In this part, the work is devoted to the mutual interweaving of the roles of teaching professions, while dealing with the specifics of this system, as well as its pros and cons. Both of these sections are represented in each chapter. In the end, the thesis deals with a possible solution for the coordination of this interweaving of roles, which could contribute to the improvement of the set system
