Resumo: Dentre as frutíferas exóticas, a pitaya vermelha (Hylocereus undatus) apresenta potencial como opção para diversificação da fruticultura nacional e incremento de renda no campo. Os cultivos com essa frutífera no Brasil ainda são poucos e há necessidade de informações locais com a finalidade de subsidiar potenciais produtores. Neste sentido, o presente trabalho teve por objetivo: i) identificar a co-existência dos estágios juvenil e adulto e o efeito na propagação da pitaya por estaquia; ii) estudar anatomicamente as raízes adventícias de estacas de pitaya; iii) avaliar o desenvolvimento e o estado nutricional da pitaya em função da intensidade luminosa e adubação orgânica. No primeiro estudo, a posição de coleta da estaca exerceu efeito quantitativo na formação de raízes da pitaya, as estacas juvenis apresentaram 35% mais estacas com raízes que estacas adultas, permitindo concluir que os estágios juvenil e adulto co-existem no dossel da pitaya. No segundo estudo, observou-se que as raízes adventícias em estacas de pitaya originam-se no periciclo, não ocorre formação de raízes a partir de calos e não há a formação de calos em estacas de pitaya. A partir do terceiro estudo infere-se que no cultivo da pitaya é necessária cobertura contra a incidência direta dos raios solares, onde a tela de propileno com 50% ou 75% de luminosidade podem ser usados, os níveis de esterco influenciaram significativamente as concentrações de N, P, K e Na, a concentração no tecido vegetal do N, P, K, S, B, Zn e Na foram incrementadas com o aumento do nível de esterco fornecido à planta e o fornecimento de 20 L.cova-1 de esterco bovino pode ser adotado como quantitativo no preparo de covas de pitaya. / Abstract: Among the exotic fruitful species, pitaya (Hylocereus undatus) presents potential as an option for diversification of Brazilian fruit culture and incomes enhancement in land. This fruitful is little cultivated in Brazil and local information is need to inform potential farmers. In this way, the present work had as objective: i) to identify the co-existence of juvenile and adult stages and it's effects on cutting propagation of pitaya; ii) to study anatomically the adventitious roots of pitaya cuttings; iii) to evaluate the development and nutritional status of pitaya as a function of light intensity and organic fertilization. In the first study, the position from which the cutting is taken had an quantitative effect on root formation of pitaya, juvenile cuttings presented 35% more cuttings with roots than adult cuttings, allowing it concludes that juvenile and adult stages co-exist in pitaya canopy. In the second study it was observed that the adventitious roots of pitaya cuttings initiate at the pericycle, there is no root formation from callus and there is no callus formation on pitaya cuttings. From the third study it infers that in pitaya cultivation a covering against light rays is need, where a shade degree of 50% or 75% can be used, the organic manure levels influenced significantly the concentrations of N, P, K and Na, the stem concentration of N, P, K, S, B, Zn and Na were enhanced with organic fertilizer level increasing and the 20 L/plant level can be adopted as quantitative for cave preparation for pitaya cultivation. / Orientador: Antonio Baldo Geraldo Martins / Coorientador: Eduardo Sanches Stuchi / Banca: Aparecida Conceição Boliani / Banca: João Alexio Scarpare Filho / Banca: Carlos Ruggiero / Banca: João Carlos de Oliveira / Doutor

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The experiment was carried out to evaluate the time pattern is used by heifers, at two phenological stages of ryegrass (Lolium multiflorum Lam.), in four daily shifts. Heifers remained exclusively on pasture or grazing and receiving a supplement (oats or corn grain), in the proportion of 0.93% of body weight. Supplements were fed at 14 o'clock, Monday to Saturday. The grazing was continuous with a variable number of animals. The experimental design was completely randomized in a sub-subdivided plots arrangement. Ingestive behavior was assessed by 24 hours of visual observation, in four evaluation dates: two in the vegetative stage and two in the reproductive stage. Grazing time, ruminating and other activities, the number, duration and interval between meals were studied. Heifers receiving supplement remain less time at feeding station and perform fewer bites daily. In the reproductive stage of the ryegrass supplemented heifers stay longer in other activities. The grazing time of heifers receiving supplement is lower in the morning shift and in the night shift. The duration of the meals is lower at night, when the heifers receive supplement. The pattern of time use of the heifers is altered by receiving supplement and the change of the structural and qualitative characteristics of ryegrass during the phenological growth stages. / O experimento foi desenvolvido com o objetivo de avaliar o padrão do uso do tempo por bezerras, durante dois estádios fenológicos do azevém (Lolium multiflorum Lam.), em quatro turnos diários. As bezerras permaneceram exclusivamente em pastejo ou em pastejo e recebendo suplemento (grão de aveia ou grão de milho), na proporção de 0,93% do peso corporal. Os suplementos foram fornecidos às 14hs, de segunda-feira a sábado. O método de pastejo foi contínuo com número variável de animais. O delineamento experimental foi inteiramente casualizado, seguindo a estrutura de parcelas sub-subdivididas. O registro dos dados de comportamento ingestivo foi realizado durante 24 horas, por observação visual, em quatro datas de avaliação: duas no estádio vegetativo e duas no estádio reprodutivo. Avaliaram-se os tempos de pastejo, de ruminação e de outras atividades, além do número, tempo de duração e o intervalo entre refeições. Bezerras que recebem suplemento permanecem menos tempo na estação alimentar e realizam menor número de bocados diários. No estádio reprodutivo do azevém, as bezerras suplementadas permanecem por mais tempo em outras atividades. O tempo de pastejo das bezerras que recebem suplemento é menor no turno da manhã e no turno da noite. A duração das refeições é menor no período noturno quando as bezerras recebem suplemento. O padrão do uso do tempo das bezerras é alterado pelo recebimento de suplemento e pela mudança das características estruturais e qualitativas do azevém durante os estádios.

The main objective was to create a normative model of determining the value of early stage for companies in the seed and start up stage. The model should be applicable to entrepreneurs and investors, taking into account the assessment of the value of qualitative factors. Another aim was to identify the significant factors affecting the value of early stage companies in the seed and start up stage, i.e. at a time when there are no or very little revenues. Based on a research among investors and other experts on the valuation of early stage companies and venture capital, the most significant factors were not only identified, but also determined by their weight. The quality of evaluating investment opportunities has a major impact on the profitability of the investor´s capital. Current knowledge of the key value drivers and the mechanisms of valuation can help businesses to set realistic expectations when trying to raise capital to finance the startup of the project. It is therefore necessary to provide a clear methodological framework applicable to both parties of investing. The actual research was divided into two phases - individual interviews with investors and questionnaires. It was confirmed that the most crucial factors are those associated with quality management and company founders.

The purpose of this project is to assess the production level one person can achieve when directing, designing, and managing all aspects of a major theatrical production. It will identify strategies and techniques which are crucial for success in the areas of theatrical design and management.

Balancing scheme of the turbine is defined at the beginning of the thesis. Then design of the regulation stage and reaction stages is accomplished. The calculation (thermodynamic and strength) is computed for mentioned two parts. For thermodynamic calculation is used ca/u method. In closing the design of the seal system is made.

Title: #InstaRealEstateAgent - A qualitative study of real estate agents' use of Instagram Authors: Marcus Holm and Tilda Hygstedt Aim: The purpose of this study is to examine how and why real estate agents' use the social media platform Instagram as a work tool. Furthermore, the study also intends to investigate how they create credibility and present themselves by using Instagram and what the pros and cons are when mixing private and work-related content.  Method/Material: The main method used in this study is qualitative interviews with five real estate agents from different agencies in Stockholm. The interviews have been complemented with content analysis of image and text of four Instagram posts from each real estate agent. Main results: The main results from this study show that the real estate agents who participated use Instagram to show who they are, maintain contact with existing clients but also as a type of portfolio. They want to appear open, positive and hard-working and therefore combine content from both private and working life. In this way, customers and others can get a clear picture of who they are and what they like. However, they believe that one must be careful when sharing events from private life. Too much and the wrong kind of things can damage one's reputation and credibility.
