O presente estudo teve por objetivo avaliar o comportamento morfológico e produtivo da linhagem de algodão 96/319 sob espaçamentos ultra-adensado, adensado e convencional entre fileiras e número de plantas por metro linear. Os experimentos foram conduzidos em área experimental pertencente ao Instituto Agronômico de Campinas, município de Campinas e, em área agrícola no município de Leme, ambos no Estado de São Paulo, nos anos agrícolas de 1999/00 e 2000/01. O delineamento experimental foi o de blocos ao acaso em esquema fatorial, com 6 repetições, sendo três espaçamentos entre linhas (0,30, 0,60 e 0,90 m) e duas densidades de plantas por metro linear (7 e 10). Em cada parcela experimental foram marcadas quatro plantas ao acaso e analisados os seguintes parâmetros: altura média final das plantas, altura de inserção do 1º ramo frutífero, número de ramos vegetativos e reprodutivos e número de capulhos por planta. Na área útil de cada parcela foi determinada a produção de algodão em caroço e, em amostras de 20 capulhos por parcela, foram realizadas as análises dos caracteres agronômicos de laboratório (massa média de um capulho, massa de 100 sementes e porcentagem de fibra) e das características tecnológicas da fibra (comprimento, uniformidade de comprimento, tenacidade e micronaire e maturidade). De acordo com os dados experimentais obtidos, pôde-se concluir que: no espaçamento ultra-adensado, a produção de algodão em caroço foi, em média, 16% superior em relação ao espaçamento convencional; quanto à interação espaçamento entre linhas e densidade de plantas na linha, maior população de plantas resultam em menor número de capulhos por plantas e maior a produção de algodão em caroço por unidade de área; quanto menor o espaçamento entre linhas, maior a altura média final das plantas e o número de ramos vegetativos e, menor o número de ramos frutíferos e o número de capulhos por planta; quanto maior a densidade de plantas na linha, maior a altura de inserção do primeiro ramo frutífero e o número de ramos vegetativos; quanto menor o espaçamento entre linhas, menor a massa de um capulho, a massa de 100 sementes e a porcentagem de fibra; e, quanto maior a densidade de plantas na linha, menor a massa de um capulho; dentre as características tecnológicas da fibra, quanto menor o espaçamento, menor o índice micronaire e a maturidade da fibra. / The main objective of the present work was to study the morphological and productive behavior of cotton line 96/319 under ultra-narrow row, narrow row and conventional row and plants per linear meter. The experiments were carried out in an experimental area belonging to the Instituto Agronômico de Campinas, Campinas city and in commercial agricultural area in Leme city, both in São Paulo state, during the 1999/00 and 2000/01 season. The experimental design was in randomized blocks with six replications, three rows (0,30, 0,60 and 0,90 m between lines) and two densities (7 and 10 plants per linear meter). Four plants per plot were labeled and analyzed for the average plant height, insertion height of the first fruit branch, number of vegetative and fruit branches and open bolls per plant. The cotton yield was determinated in the useful area of each plot and samples of 20 open bolls randomized chosen per plot were analyzed for agronomical lab characteristics (average open boll mass, mass of 100 seeds and fiber percentage) and fiber technological characteristics (length, length uniformity, strength, micronaire and maturity). According to the experimental data obtained it was possible to conclude: cotton yield for the ultra-narrow was average 16% higher than the yields for the conventional row; for row and plant density interaction, higher plant population resulted smaller number of open bolls per plant and higher cotton yield per unit area; smaller row resulted higher average plant height and number of vegetative branches, and smaller number of fruit branches and open bolls per plant; higher plant density resulted higher insertion height of the first fruit branch and number of vegetative branches; smaller row resulted smaller average open boll mass, mass of 100 seeds and fiber percentage; and higher plant density resulted smaller average open boll mass; among fiber technological characteristics, smaller row resulted smaller micronaire and fiber maturity.

The diploma thesis deals with a project of a new multifunctional building in Pelhřimov. The object is composed by four above-ground and one underground floor. Commercial premises are located on the first above-ground floor. These premises consist of a travel agency, bakery, bookshop and sports outfitters. Two individual administrative premises can be found on the second floor. Eight flats were designed on the third and the fourth above-ground floor. On each of these floors, there are four flats; two of them were designed as two-bedroom and two of them as three-bedroom flat. A common area and a row garage can be found on the underground floor. The construction system of the object is a combination of reinforced concrete frame and a masonry system. The object is roofed with a warm flat roof with a typical sequence of layers.

This master´s thesis deals with the determination of the stiffness of a preloaded double-row bearing with an angular contact in the relevant conditions. The introduction describes the basic knowledge about double row angular contact bearings and the relationship between internal clearance, preload and other effects on stiffness. An overview of studies dealing with bearing stiffness and an overview of devices used for experimental stiffness determination is given. Subsequently, the solution itself is described, in which the theoretical calculation of the bearing stiffness was performed first. To determine the experimental values, it was necessary to design and construct experimental device for testing the bearing in the relevant conditions. The effect of material and temperature on the stiffness of the bearing was determined from the measured data and theoretical calculations. The result of this thesis is a functional device, which was used to test the bearing in the thermal chamber.

The modern trend of gas turbines design is towards lighter, highly efficient,and more compact engines. Such situation imposes on engineers to continuouslysearch for improved and optimum designs. The thesis presented aims at researching possible performance improvements regarding axial gapdistance in transonic compressors. Decreasing the axial gap would result inlighter engines and achieve design goals. The influence of decreasing the axialgap on performance and structure integrity should be throughly analyzed. This thesis work includes numerical investigations on the axial gap distance effect on performance efficiency and related unsteady aerodynamics phenomena. The first one and a half compressor stages of a Siemens Gas Turbine are modeled in ANSYS CFX. Different axial gap models are simulated for differentconfigurations. The steady state solution is obtained to be initialized for transient time marching calculations. Furthermore, the computational cost of transient calculations is reduced through a geometry scaling technique. The unsteady behavior is further analyzed by a Harmonic Balance solver implemented in STAR-CCM+ software, and compared to a reference case transient calculations. The results obtained supports the presence of an optimalaxial gap distance for maximum efficiency in transonic compressors. Further, the harmonic balance method shows good possibilities for cost and time reductions in transonic compressors performance calculations.

In today’s society our residents and premises consume 38 % of the total energy use in Sweden. 2011 that number corresponded to 77,8 TWh/year. Governments and the public’s strive to lower the energy use and the European Union’s goal that all member countries should lower their energy consumption with 20 % until year 2020 creates incentives to renovations and energy efficiency measures. A possible measure that could lead to reduced energy consumption for rental apartments and smaller residences like row-houses is to install individual metering. Individual metering is a method to measure how much energy is consumed in residences. Devices are installed in homes and can measure the water and heat consumption and let the residence pay for what is actually used. In this report the consumption and the costs for heat and warm water and the attitude to individual metering between two row-house areas is investigated. Both areas are located in Stockholm, in Huddinge and Farsta, where one of the areas has installed individual metering. Our study shows difference of the consumption and costs between the two areas. The installation of individual metering has result in a higher awareness for the people living in that area which has led to a reduced consumption and cost. The attitude for individual metering is positive in both areas and unchanged after the installation of individual metering. / I dagens samhälle förbrukar våra bostäder och lokaler ca 38 % av den totala energianvändningen i Sverige. 2011 motsvarade den siffran 77,8 TWh/år. Myndigheter och allmänhetens strävan att minska energiförbrukningen och EU:s målsättning att alla medlemsländer ska sänka sin energikonsumtion med 20 % fram till år 2020 skapar incitament för renoveringar och energieffektiviseringsåtgärder. En möjlig åtgärd för hyreslägenheter och mindre boenden som radhusområden är införandet av individuell mätning. Individuell mätning är en metod för att mäta energiförbrukningen i bostäder. Mätare installeras i hemmen och kan mäta vatten och värme och låter de boende betala för det de faktiskt konsumerar. I rapporten undersöks förbrukningen och kostnaderna för värme och varmvatten samt hur de boendes inställning är till individuell mätning mellan två radhusområden. Båda är belägna i Stockholm, i Huddinge respektive Farsta, där ett av områdena har infört individuell mätning. Studien visar skillnader på förbrukningen och kostnaderna mellan områdena jämfört med det andra området). Införandet av individuell mätning har medfört att de boende i området fått en högre medvetenhet vilket lett till en minskad förbrukning och kostnad. Inställningen och attityden till individuell mätning är lika positiv i båda områdena och attityden är oförändrad efter införandet i det området.

Improved management strategies are needed to increase yield production and quality. The study aimed to determine suitable cultural practices for improved corn production. Experiments were set up at Verona and Stoneville, Mississippi, from 2020 to 2022. Treatments included row configurations (single and twin-row), plant populations (79,000 and 99,000 seeds ha-1), and six combinations of nutrients with or without fungicide. The nutrients evaluated were two nitrogen rates 235 and 314 kg N ha-1, phosphorus 45 kg P ha-1, potassium 112 kg K ha-1, sulfur 22 kg S ha-1, and zinc 11 kg Zn ha-1, and fungicide at 272 ml ha-1. In trial 1 (Addition), nutrients were added incrementally, whereas in trial 2 (Deletion) nutrients were withheld in a stepwise manner. Within nutrient treatments, results were erratic among years and sites. Overall, producers must find a balance in terms of yield and profit by taking soil testing and fertilizer prices into consideration.
