This thesis is to describe bases of assessment of personal income tax in selected countries -- the Czech Republic, Slovak Republic, Slovenia, Austria and Polland. Its aim is to compare the number of partial bases of assessment and their content, expenditures and expenses as a percentage of income.

Einleitung: Eisenmangel ist ein häufiges Problem bei Ausdauersportlern, da dieser die Leistungsfähigkeit einschränken und zu einer Blutanämie führen kann. Von den klassischen Eisenstoffwechselparametern sind nur wenige geeignet, den tatsächlichen Eisenstatus anzuzeigen, da sie durch sportliche Aktivität per se beeinflusst werden können. In der Studie wird die Wertigkeit moderner Eisenstoffwechselparameter im Ausdauersport untersucht. Ergebnisse und Diskussion: Der Hämoglobingehalt der Retikulozyten (CHr) und der prozentuale Anteil der hypochromen Erythrozyten (% HYPO) bleiben als moderne Parameter der Eisenstoffwechseldiagnostik auch nach regenerativen, extensiven sowie intensiven Ausdauerbelastungen konstant. Sie zeigen somit unbeeinflusst von der (Ausdauer-)Sportart als auch von der Belastungsdauer und –intensität die aktuelle Eisenversorgung der Erythropoese im Knochenmark an. Als Monitoringparameter im Rahmen einer Eisensubstitution sind der CHr sowie der prozentuale Anteil hypochromer Retikulozyten sensible Parameter, mit denen sich schnell und zuverlässig die Effektivität einer oralen Eisensubstitution nachweisen lässt. Der Eisenstatus kann durch die alleinige Bestimmung des CHr bzw. des % HYPO nicht exakt ermittelt werden. Im Gegensatz zum Einsatz bei klinischen Fragestellungen können sie zu diesem Zeitpunkt in der Sportmedizin allenfalls nur ein ergänzender Parameter in der Differentialdiagnostik eines Eisenmangels sein. Die für Ausdauersportler ermittelten Referenzwerte liegen bei 28,8-35,9 pg für den CHr und bei 0-0,5 % für die hypochromen Erythrozyten. Ein belastungsbedingter Anstieg des Eisen-regulierenden Hormons Hepcidin könnte auf Grund seiner inhibitorischen Wirkung auf die intestinale Eisenabsorption sowie auf die Freisetzung von Eisen aus den Makrophagen zur Entwicklung von Eisenmangel-zuständen führen. Die Entwicklung von Hepcidin-Antagonisten könnte in Zukunft therapeutische Anwendungen finden. / Introduction: Athletes are commonly diagnosed with iron deficiency, particularly those involved in endurance sports. It often not only decreases athletic performance but also contributes to the development of anaemia. Many biochemical markers are used to evaluate body iron stores but some of them are affected by physical exercises. This study was designed to investigate new haematological parameters in endurance athletes. Results and discussion: Reticulocyte hemoglobin content (CHr) and percentage of hypochromic red cells (% HYPO) were highly stable in athletes subjected to varying physical loads. Furthermore, they were neither affected by different forms of endurance sports nor by their duration and intensity. These modern indices are able to reflect the availability of iron during erythropoiesis at all times. In the early prediction of response to oral iron supplementation, the reticulocyte indices CHr and % HYPOr (percentage of hypochromic reticulocytes) are the most sensitive parameters. However, it is not possible to assess the iron status in athletes by CHr and % HYPO alone. In contrast to other clinical cases they can only be an additional parameter in the differential diagnosis of iron deficiency. The calculated reference range for endurance athletes are 28,8 - 35,9 pg for CHr and 0-0,5 % for % HYPO. As the iron-regulating hormone hepcidin is inhibiting the absorption of iron from the diet at the site of the duodenal enterocytes and blocking the release of iron from macrophages that have collected senescent erythrocytes, an exercise induced up-regulation of hepcidin activity might potentially be a new mechanism causing iron deficiency in athletes. Therefore, the development of hepcidin antagonists could prove to be helpful with regard to therapeutic utilization.

Plugged and abandoned well pads throughout the Uintah Basin face reclamation challenges due to factors including a harsh climate, invasive species, and high salt loads. Finding ways to alleviate soil sodicity could improve soil reclamation success. Gypsum, sulfur, activated carbon, and Biochar are being applied to improve soil parameters negatively impacted by sodicity, but the direct impact of these amendments on Uintah Basin soils is still largely unknown. The aim of this study was two-fold. (1) Evaluate the effectiveness of gypsum, sulfuric acid, Biochar, activated carbon, and combinations of these amendments in reducing the impact of soil sodicity of the Desilt and Conglomerate soils by measuring amendment impact on percent dispersion, saturated hydraulic conductivity, crust bulk density, infiltration, and crust formation. (2) Compare a crust bulk density method using ImageJ to the clod wax density method and a modified linear extensibility percent equation to the linear extensibility percent equation to assess whether the novel methods can be used to accurately measure and calculate soil crust bulk density and shrink swell potential while reducing human error and analysis time.

The “temporal variables” here include pause duration, pause percentage, articulation rate, speech rate, and utterance length. Besides those temporal variables, two pause locations are observed: “between” or “within” major constituents (sentences and clauses). The two languages under discussing are Mandarin Chinese and English, and the two speech styles are reading and story-telling. We hope to understand the processes of reading and story-telling in Mandarin and English. The data of the present study are speech from sixteen males and sixteen females of Cheng-chi University. All of them are native speakers of Mandarin Chinese, and started to learn English at junior high school. They are asked to read a story either in Chinese or in English and tell the story on their own. Also, for fear that subjects’ performance may be influenced by the order of reading and story-telling, half of the same group are asked to read before telling story, and the other tell the story before reading. So we have two independent variables: language and style. The design of the experiment is 2×2. There are three important results in our study. 1. Pause duration is shorter, pause percentage is lower, articulation rate and speech rate is faster, and utterance length is longer in Mandarin than in English. 2. As far as speech style is concerned, pause is shorter and fewer in reading than in story-telling, with slower articulation rate and speech rate, and longer utterance. 3. More pauses are found to appear between major constituents in Mandarin than in English, in reading than in story-telling. However, fewer pauses are found within major constituents in Mandarin than in English; in reading than in story-telling.

The aim of this study was firstly to perform, from the existing literature, a SWOT ("Strengths, weaknesses, opportunities and threats") analysis of the boerbok industry. Secondly, to design a case study where a number of management accounting evaluation techniques (i.e. performance measurement (short–term focus), capital investment evaluation (long–term focus) and risk have been identified to compare the financial results of different scenarios between boerbok, sheep and cattle farming. In the case study, Scenarios 1, 2 and 3 assumed a farm size of 200 hectares and capital available of R200 000, R500 000 and R900 000, respectively. Scenarios 4, 5 and 6 assumed a farm size of 500 hectares, with the same capital as the above amounts, respectively; and Scenarios 7, 8 and 9 assumed a farm size of 900 hectares, with the same capital as the above amounts, respectively. The study concluded, from the SWOT analysis, that the boergoat inherently has the potential to be an important source of red meat in future markets. The sum total of the management accounting techniques indicated that the boerbok is in general financially the best specimen choice for farming, e.g. in seven of the nine scenarios it has the highest score. The recommendation is that the user must determine which of performance (short–term), return on capital (long–term) or risk are the most important considerations before a decision is made regarding to the choice of preferred specimen. The study's recommendation is to select boerbok farming in case both short–term financial performance and long–term return on capital are the most important factors. If risk is the major consideration, cattle farming should be selected. If the overall financial analysis outlined in the study is considered, boerbok farming should be selected, followed by sheep farming. Note that these recommendations are made for specific scenarios; therefore, the general recommendation is that each decision–maker should take his/her own unique situation's variables into account in this financial analysis. The limitations of the study, which arose because a number of assumptions were made, are as follows: The results of the investigation are only valid for the Potchefstroom and surrounding areas and, carrying capacity, based on this area's average, may even differ in the area; Dosage is based on the needs of the environment as in January 2011; Buying and selling prices are as at January 2011; The input costs for livestock handling infrastructure may differ, as farming practices and approaches differ; The physical shape of the farm could have a direct impact on the fencing expenditure; Lamb and calf growth percentages may vary as a result of different farming practices and approaches; and The combination of initial capital and farm size may influence the results. As a result of these constraints (assumptions), it is very risky to generalise, but the practical value of the study is that a Microsoft Excel programme was developed, which can be used for calculations, similar to calculations in this study, which is available at the following web address: http://sites.google.com/site/rooivleisvergelyking/. Therefore, variables such as farm size, capital available, carrying capacity, costs and prices can be changed for each unique scenario, and the results will be calculated accordingly. The contribution of this study is that it supports the decision regarding the choice between the types of red meat farming for several unique scenarios, because every land user can determine which of these species are recommended according to the different management accounting evaluation techniques. The value of the study is that it is the first attempt where the viability of three species of red meat farming is compared by means of a case study with different scenarios. The gap for further research that should be done is as follows: The number of evaluation techniques can be extended to give more substance to the results; The number of species in the comparison can be extended; An analysis of the behaviour of costs between the different scenarios can be done; and The optimal combination of farm size and capital available can be determined. / Thesis (M.Com.

Concern regarding the health effects of indoor air quality has grown in recent years, due to the increased prevalence of many diseases, as well as the fact that many people now spend most of their time indoors. While numerous studies have reported on the dynamics of aerosols indoors, the dynamics of bioaerosols in indoor environments are still poorly understood and very few studies have focused on fungal spore dynamics in indoor environments. Consequently, this work investigated the dynamics of fungal spores in indoor air, including fungal spore release and deposition, as well as investigating the mechanisms involved in the fungal spore fragmentation process. In relation to the investigation of fungal spore dynamics, it was found that the deposition rates of the bioaerosols (fungal propagules) were in the same range as the deposition rates of nonbiological particles and that they were a function of their aerodynamic diameters. It was also found that fungal particle deposition rates increased with increasing ventilation rates. These results (which are reported for the first time) are important for developing an understanding of the dynamics of fungal spores in the air. In relation to the process of fungal spore fragmentation, important information was generated concerning the airborne dynamics of the spores, as well as the part/s of the fungi which undergo fragmentation. The results obtained from these investigations into the dynamics of fungal propagules in indoor air significantly advance knowledge about the fate of fungal propagules in indoor air, as well as their deposition in the respiratory tract. The need to develop an advanced, real-time method for monitoring bioaerosols has become increasingly important in recent years, particularly as a result of the increased threat from biological weapons and bioterrorism. However, to date, the Ultraviolet Aerodynamic Particle Sizer (UVAPS, Model 3312, TSI, St Paul, MN) is the only commercially available instrument capable of monitoring and measuring viable airborne micro-organisms in real-time. Therefore (for the first time), this work also investigated the ability of the UVAPS to measure and characterise fungal spores in indoor air. The UVAPS was found to be sufficiently sensitive for detecting and measuring fungal propagules. Based on fungal spore size distributions, together with fluorescent percentages and intensities, it was also found to be capable of discriminating between two fungal spore species, under controlled laboratory conditions. In the field, however, it would not be possible to use the UVAPS to differentiate between different fungal spore species because the different micro-organisms present in the air may not only vary in age, but may have also been subjected to different environmental conditions. In addition, while the real-time UVAPS was found to be a good tool for the investigation of fungal particles under controlled conditions, it was not found to be selective for bioaerosols only (as per design specifications). In conclusion, the UVAPS is not recommended for use in the direct measurement of airborne viable bioaerosols in the field, including fungal particles, and further investigations into the nature of the micro-organisms, the UVAPS itself and/or its use in conjunction with other conventional biosamplers, are necessary in order to obtain more realistic results. Overall, the results obtained from this work on airborne fungal particle dynamics will contribute towards improving the detection capabilities of the UVAPS, so that it is capable of selectively monitoring and measuring bioaerosols, for which it was originally designed. This work will assist in finding and/or improving other technologies capable of the real-time monitoring of bioaerosols. The knowledge obtained from this work will also be of benefit in various other bioaerosol applications, such as understanding the transport of bioaerosols indoors.

The study examined the use of multiple representations such as the real world, written symbols, spoken symbols, diagrams and manipulatives by learners to promote the learning of percentages and fractions through social interaction. This investigation was carried out through a teaching and learning programme which was developed and implemented by me, the researcher. The effect of the implemented programme was the main focus of the research. The qualitative study was oriented in the interpretive paradigm – a paradigm that seeks to understand the meaning attached to human actions. Twenty learners participated in the implementation of the programme and 9 learners were selected for focus group interviews. The purpose of the interviews was to explore learners' understanding and feelings about the use of multiple representations in the learning of percentages and fractions through social interactions. The other tools employed in this study were pre-and-post diagnostic tests, observations, learners' work and a journal. The pre-test was used to determine learners' prior knowledge for the program design and implementation, while the post-test and learners' work were used to analyze the effect of the programme. Observations were used to investigate how multiple representations promoted or did not promote the learning of percentages and fractions. The teacher's journal was to record and reflect on any relevant information gathered on each lesson observed. The data shows that the effective use of multiple representations helped learners learn the concept of percentages and fractions better. Learners were able to look at representations in useful ways; multiple representations made some aspects of the concept clear; and multiple representations enabled learners to correct errors. Through the interaction between the teacher and learners, the following was found: all the learners changed words to change focus; learners made links between multiple representations; the learners deepened their concepts of percentages and fractions; learners could convert between fractions using multiple representations; learners could work out percentages of a quantity; and learners could express one quantity as a percentage of another. Furthermore, through the interaction between learners and learners all learners could identify more equivalent fractions of an initial fraction which was given to them; and they could increase and decrease a quantity by a given percentage. On the basis of this research, it can be concluded that the programme promoted the learning of percentages and fractions through three effective methodologies. The first methodology consisted of the effective use of multiple representations; the second methodology concerned the interaction between the teacher and learner during the learning process and the last methodology related to the interaction between the learners - interactions that were not strongly mediated by the teacher. I would recommend that teachers use these three effective approaches when teaching percentages and fractions to promote the learning of the concepts.

Para o primeiro objetivo, os dados foram coletados em 30 parcelas permanentes, sendo 16 convencionais e 14 g?meas, em que foi analisado o efeito do desbaste (parcela convencional) e da fertiliza??o (parcela g?mea) sobre o crescimento das ?rvores. O desbaste foi realizado aos 81 meses, com intensidade de 20%, 35% e 50% de ?rea basal presente, eliminando os piores indiv?duos, e a fertiliza??o aplicada aos 99 meses. As vari?veis analisadas resultantes da totaliza??o dos dados das parcelas foram ?rea basal (B), di?metro m?dio (q), altura total m?dia (Ht) e volume total com casca (Vcc). A an?lise dos dados constituiu-se na compara??o do efeito de vari?veis em rela??o ? idade por meio de modelo de regress?o, e foi realizada aos 99 meses ap?s o desbaste e aos 81 meses ap?s a fertiliza??o. Para atender ao segundo objetivo, os dados foram coletados em 34 parcelas permanentes, instaladas em povoamentos com espa?amento de 3,0 x 2,5 metros, em dois s?tios diferentes. Essas parcelas foram medidas aos 24, 36, 48, 60 e 72 meses, durante o Invent?rio Florestal Continuo (IFC). O M?todo dos Ingressos Percentuais foi empregado para determinar a ?poca de realiza??o do primeiro desbaste. Para projetar as distribui??es diam?tricas, para idades superiores ? ?ltima medi??o, utilizou-se um modelo de distribui??o diam?trica, que consiste na recupera??o dos par?metros de uma fun??o de densidade de probabilidade (f.d.p) ao longo dos anos. Neste trabalho, adotou-se a fun??o Weibull, que foi ajustada pelo m?todo de m?xima verossimilhan?a. A partir das informa??es de n?mero de indiv?duos e valores estimados para os par?metros da fun??o Weibull, ? e ?, de ambas as distribui??es diam?tricas analisadas, calculou-se o ingresso percentual (IP) de ?rvores em classes de di?metro sucessivas ao longo do tempo. Para determinar a ITD, foi ajustado um modelo exponencial justaposto a um modelo linear simples. A ITC foi definida como o momento em que o incremento corrente ? igual ao incremento m?dio, sendo a produtividade volum?trica, ao longo do tempo, estimada pelo modelo de Clutter. O desbaste apresentou influ?ncia para as vari?veis ?rea basal, volume total com casca e di?metro m?dio, por?m n?o influenciou a altura total m?dia. A fertiliza??o realizada ap?s o desbaste n?o influenciou a produ??o das vari?veis analisadas. A idade t?cnica de desbaste de um povoamento de eucalipto localizado em um s?tio de maior capacidade produtiva ocorre antes, comparado com a idade de desbaste de um povoamento em um local de produtividade inferior. Esse mesmo comportamento ocorre para a idade t?cnica de corte. Para um mesmo s?tio, a idade t?cnica de desbaste ocorre ap?s a idade t?cnica de corte. / Disserta??o (Mestrado) ?

For the first objective, the data were collected in 30 permanent plots, 16 conventional and 14 twins, in which were analyzed the effect of thinning (conventional plot) and fertilization (twin plot) on tree growth. The thinning was carried out at 81 months, with intensity of 20%, 35% and 50% of present basal area, eliminating the worst individuals, and the fertilization applied at 99 months. The analyzed variables resulting from the summation of data from plots were basal area (B), quadratic diameter (q), mean total height (Ht) and total volume with bark (Vcc). The data analysis consisted in the comparison of variable effects, in relation to age, through regression model, and was held at 99 months after the thinning and 81 months after fertilization. To attend the second objective, the data were collected in 34 permanent plots, installed in stands with spacing of 3.0 x 2.5 meters, in two different sites. These plots were measured at 24, 36, 48, 60 and 72 months, during the Continuous Forest Inventory (IFC). The Percentages Ingress Method was employed to determine the epoch of realization of the first thinning. To project the diameter distributions for older ages after the last measurement, there was used a diameter distribution model, which consists in recovering the parameters of a probability density function (f.d.p) along the years. In this work, it was adopted the Weibull function, which was adjusted by the maximum likelihood method. From the information of number of individuals and estimated values for the parameters of the Weibull function, ? and ?, from both analyzed diameter distributions, it was calculated the percentage ingress (IP) of trees in successive diameter classes along the time. To determine the ITD it was adjusted an exponential model juxtaposed to a simple linear model. The ITC was defined as the moment that the current increment is equal to the average increment, in which the volumetric productivity along the time was estimated by Clutter model. The thinning presented influence for the variables basal area, total volume with bark and quadratic diameter, however did not affect the mean total height. The fertilization performed after thinning did not influence the production of the analyzed variables. The thinning technical age of an eucalypt stand located in a higher productive capacity site occurs earlier compared to the thinning age of a stand in a lower productivity site. This same behavior occurs for the harvest technical age. For the same site, the thinning technical age occurs after the harvest technical age.
