Optimização da adubação mineral em trigo regado e sua interacção com o nível de estrumação

Com o objectivo de estudar uma possível optimização da adubação mineral de trigo mole e sua interacção com estrumação, foi desenvolvido um ensaio onde, numa área com trigo mole, regado e em sementeira directa, se interagiram os 3 macronutrientes principais, com 3 níveis de estrume. Para esta interacção foram analisados vários parâmetros que resultaram em 3 parâmetros principais, produção de grão, de palha e também as extracções totais de N, P, K da cultura. De acordo com os resultados obtidos pôde-se verificar que a aplicação de estrume não revelou efeitos positivos na produção de grão/palha do trigo. A elevada fertilidade do solo em sementeira directa ofereceu à cultura uma base sustentável para o seu desenvolvimento sem que seja necessária a adubação mineral actualmente padronizada. Por fim foi evidente a importância da antecipação da 1ª cobertura realizada no trigo para o estado de afilhamento, factor que contribuiu significativamente para o sucesso da cultura; Optimization of mineral fertilizer in irrigated wheat and its interaction with the level of manure ABSTRACT: With the aim of studying the optimization of mineral fertilization of common wheat and their interaction with manure, it was developed a study where in an area with soft wheat, watered and with no tillage, we interacted 3 main macronutrients and 3 manure levels. To this interaction were analyzed several parameters that resulted in three major parameters, production of grain and straw and also the total extraction of N, P, K culture. According to the results it was observed that the application of manure did not show positive effects in the production of grain / wheat straw. The high soil fertility on direct seeding culture offered a sustainable base for its development without requiring high fertilization. Finally it was evident the importance of the anticipation of the 1st cover held in wheat, a factor that contributed significantly to the success of the crop.

Qualidade e comunicação nas organizações de saúde : Aplicação prática no Hospital CUF Infante Santo

A presente dissertação discute a cada vez maior exigência de qualidade nas organizações de saúde, que deve ser encarada como uma ferramenta de gestão e de mudança, e a necessidade intrínseca de uma melhor e mais abrangente rede de comunicação, que se impõe para a transmissão de informação e conhecimento, numa sociedade que a uma velocidade atroz se encontra em constante mutação e desenvolvimento. Neste sentido, a temática em estudo assume particular importância no contexto actual, pois apenas a qualidade representa o garante da subsistência da organização abrindo caminho à eficiência e à eficácia organizacional e de interesse para a instituição, pois parte do conhecimento da percepção dos enfermeiros, que na organização de saúde estão directa e proporcionalmente relacionados com a satisfação do cliente. Os enfermeiros asseguram a manutenção dos padrões de qualidade, que a organização pretende alcançar e comunicar, sendo fundamentais na imagem global transmitida e, consequentemente, na criação de valor da própria organização. Este estudo apresenta como objectivo principal averiguar o conhecimento, o envolvimento e quais as necessidades sentidas, na perspectiva dos enfermeiros, no âmbito da comunicação organizacional, de modo a melhorar a comunicação na organização de saúde, de forma a promover uma gestão de qualidade, garantindo uma subsequente imagem global de excelência. A investigação empírica analisou de forma sistemática informação relevante na área da qualidade, da comunicação organizacional e da inovação. Assim, aplicou-se um inquérito por questionário, fundamentado nos princípios de autores como Deming (1986); Chiavenato (2004); Druker (2000); Biscaia (2000) e Jeffries, (1992), junto dos enfermeiros do Hospital CUF Infante Santo. Com a realização de uma investigação exploratório-descritiva coloca-se a tónica na definição de conceitos e na descrição de factores, através de uma abordagem híbrida qualitativa e quantitativa, foi possível empreender-se o estudo e edificar-se os resultados, que permitem fazer uma caracterização de um conjunto de necessidades a colmatar no âmbito da comunicação interna e verificar a receptividade a inovações de forma a conseguir um maior envolvimento, formação e adesão dos enfermeiros nas políticas de qualidade. As conclusões apuradas levaram à apresentação da indispensabilidade de um envolvimento dos enfermeiros na gestão organizacional ao nível das políticas de qualidade e dos processos de melhoria contínua, observando a emergência de necessidades comunicacionais, nomeadamente a intranet, numa atitude afirmativa de imposição deste canal como um importante facilitador, desde que adaptado à realidade da organização. ABSTRACT: This dissertation discusses the increasing demand for quality in health organizations, which should be seen as a management and change tool, and the intrinsic need of a better and wider communication network, which is required for the transmission of information and knowledge, in a society that is at an atrocious speed constantly changing and developing. ln this sense, the theme in study assumes particular importance in the current context, thus only the quality represents the guarantee of the continuation and existence of the organization opening the way to organizational efficiency and effectiveness and of interest to the institution, as by part of the perception knowledge of the nurses, which in the health organization are directly and proportionately related to the client’s satisfaction. The nurses ensure the maintenance of the quality standards, that the organization aims to reach and communicate, being fundamental in the global image transmitted, and consequently, in the creation of value for the organization itself. The study presents as main objective the investigation of knowledge, the involvement and which necessities needed and felt, in the nurses' perspective, within the organizational communication, as to better the communication within the health organization, in such a way to promote the quality management, guaranteeing a subsequent global image of excellence. The empirical research analyzed in systematic way information relevant in the area of quality, of the organizational communication and innovation. Thus, a survey questionnaire was applied, based on the principles of authors such as Deming (1986); Chiavenato (2004); Druker (2000); Biscaia (2000) e Jeffries, (1992), among nurses of the Infante Santo CUF Hospital. With the completion of an exploratory-descriptive research, the emphasis was put on the concepts definition and the factors description, through a quality and quantity hybrid approach, it was possible to carry out the study and edify the results, which permit in the making of a characterization of a group or set of necessities to cover in the internal communication ambit and verify the acceptability to innovations so that a greater involvement be achieved, training and adherence of the nurses in the quality policies. The conclusions reached led to the presentation of the indispensability of an involvement of the nurses in the organizational management at the level of the quality policies and the processes for continuous improvement, observing the emergency of communication needs, namely the intranet, in an affirmative attitude of imposition of this channel such as an important facilitator, as long as ifs adapted to the reality of the organization.

Aplicação de microssatélites na crioconservação da diversidade genética do cavalo lusitano

O género Equus teve origem na América do Norte e alguns exemplares migraram para a Eurásia pelo Estreito de Bering, durante a última glaciação. No fim da glaciação, todos os cavalos do continente americano extinguiram-se, mas sobreviveram nas estepes da Eurásia, na Peninsula lbérica e nas florestas da Europa Ocidental e Central. O cavalo Lusitano teve a sua origem em cavalos selvagens e domesticados da Peninsula lbérica, ocorrendo uma mistura com outros animais trazidos por eventos migratórios ocorridos no passado. Os cavalos deste gene pool contribuiram para o desenvolvimento de outras raças modernas na Europa e foram mais tarde introduzidos e dispersos pelo continente Americano, tornando-se fundadores de numerosas raças do novo mundo. A raça Lusitana é uma raça equina autóctone portuguesa, com especial relevancia económica no panorama nacional e internacional. Apesar de não ser uma raça ameaçada, alguns autores defendem que a informação genealógica disponivel (pedigrees) indica que uma utilização excessiva de um reduzido número de reprodutores machos esta a diminuir a diversidade genética da raça, tendo como consequência o aumento da consanguinidade e a diminuição do tamanho efetivo da população para cerca de metade dos valores recomendados pela FAO. No entanto, a anàlise da diversidade genética com base em 16 microssatélites (Marcadores de DNA) a um grupo de 2699 machos da raça Lusitana, nascidos entre 1985 e 2010 e inscritos como reprodutores no Livro Genealógico da raça, revelou um elevado nível de diversidade, idêntico ao encontrado na maioria das raças equinas. Dada a crescente relevância da Crioconservação, omo estratégia complementar para a conservação da diversidade genética in situ, e tendo em conta que não existe criopreservação de oocitos, embriões ou sémen, do cavalo de raça Lusitana em Banco de Genes, selecionaram-se 62 machos reprodutores (garanhões) com interesse genético para a criopreservação de sémen, quer no sentido de preservar a diversidade da raça quer no da salvaguardar em caso de calamidade; ABSTRACT: The genus Equus originated in North America and some exemplary migrated to Eurasia through the Bering Strait during the last glaciation. By the end of the last glaciation, all horses on the American continent became extinct but the genus survived in the steppes of Eurasia, in the Iberian Peninsula and on the Central and West Europe forests. The Lusitano horse breed has its origins in wild and domesticated horses of the Iberian Peninsula, where a mixture with other animals brought by migratory events in the past occurred. The horses of this gene pool contributed to the development of other modern breeds in Europe and were later introduced and spread throughout the American continent, becoming founders of numerous breeds of the New World. The Lusitano horse breed, is a Portuguese native equine breed, with special economic relevance in the national and international scene. Although not being an endangered breed, some authors argue that the available genealogical information (pedigrees) indicates that an excessive use of a limited number of stallions is decreasing the genetic diversity of the breed, resulting in the increase of inbreeding and on the decrease of the effective population size to about half of the values recommended by FAO. However, the analysis of genetic diversity based on 16 microsatellites (DNA markers) in a group of 2699 males of the Lusitano horse breed, born between 1985 and 2010 and registered as Stallions in the Studbook, revealed a high level of diversity similar to that found in the majority of equine breeds. Given the growing relevance of Cryopreservation as a complementary strategy for the conservation of genetic diversity in situ and, taking into consideration the inexistence of criopreservation for oocytes, embryos and semen, in a Gene Bank, for the Lusitano horse breed, 62 breeding males (stallions) with genetic interest for semen cryopreservation were selected in order either to preserve the diversity of the breed or as safeguard in case of calamity.

Sinterização de Ce1-XEuXO2-(X/2) para aplicação como eletrólito sólido em células a combustível de temperaturas intermediárias

Given the environmental concern over global warming that occurs mainly by emission of CO2 from the combustion of petroleum, coal and natural gas research focused on alternative and clean energy generation has been intensified. Among these, the highlight the solid oxide fuel cell intermediate temperature (IT-SOFC). For application as electrolyte of the devices doped based CeO2 with rare earth ions (TR+ 3) have been quite promising because they have good ionic conductivity and operate at relatively low temperatures (500-800 ° C). In this work, studied the Ce1-xEuxO2-δ (x = 0,1, 0,2 and 0,3), solid solutions synthesized by the polymeric precursor method to be used as solid electrolyte. It was also studied the processing steps of these powders (milling, compaction and two step sintering) in order to obtain dense sintered pellets with reduced grain size and homogeneous microstructure. For this, the powders were characterized by thermal analysis, X-ray diffraction, particle size distribution and scanning electrons microscopy, since the sintered samples were characterized by dilatometry, scanning electrons microscopy, density and grain size measurements. By x-ray diffraction, it was verified the formation of the solid solution for all compositions. Crystallites in the nanometric scale were found for both sintering routes but the two step sintering presented significant reduction in the average grain size

Construção, caracterização e aplicação de eletrodos para descarga por arco de cátodo oco

The system built to characterize electrodes and, consequently, deposited fine films are constituted by a hollow cathode that works to discharges and low pressures (approximately 10-3 to 5 mbar), a source DC (0 to 1200 V), a cylindrical camera of closed borossilicato for flanges of stainless steel with an association of vacuum bombs mechanical and spread. In the upper flange it is connected the system of hollow cathode, which possesses an entrance of gas and two entrances for its refrigeration, the same is electrically isolated of the rest of the equipment and it is polarized negatively. In front of the system of hollow cathode there is a movable sample in stainless steel with possibility of moving in the horizontal and vertical. In the vertical, the sample can vary its distance between 0 and 70 mm and, in the horizontal, can leave completely from the front of the hollow cathode. The sample and also the cathode hollow are equipped with cromel-alumel termopares with simultaneous reading of the temperatures during the time of treatment. In this work copper electrodes, bronze, titanium, iron, stainless steel, powder of titanium, powder of titanium and silício, glass and ceramic were used. The electrodes were investigated relating their geometry change and behavior of the plasma of the cavity of hollow cathode and channel of the gas. As the cavity of hollow cathode, the analyzed aspects were the diameter and depth. With the channel of the gas, we verified the diameter. In the two situations, we investigated parameters as flow of the gas, pressure, current and applied tension in the electrode, temperature, loss of mass of the electrode with relationship at the time of use. The flow of gas investigated in the electrodes it was fastened in a work strip from 15 to 6 sccm, the constant pressure of work was among 2.7 to 8 x 10-2 mbar. The applied current was among a strip of work from 0,8 to 0,4 A, and their respective tensions were in a strip from 400 to 220 V. Fixing the value of the current, it was possible to lift the curve of the behavior of the tension with the time of use. That curves esteem in that time of use of the electrode to its efficiency is maximum. The temperatures of the electrodes were in the dependence of that curves showing a maximum temperature when the tension was maximum, yet the measured temperatures in the samples showed to be sensitive the variation of the temperature in the electrodes. An accompaniment of the loss of mass of the electrode relating to its time of use showed that the electrodes that appeared the spherical cavities lost more mass in comparison with the electrodes in that didn't appear. That phenomenon is only seen for pressures of 10-2 mbar, in these conditions a plasma column is formed inside of the channel of the gas and in certain points it is concentrated in form of spheres. Those spherical cavities develop inside of the channel of the gas spreading during the whole extension of the channel of the gas. The used electrodes were cut after they could not be more used, however among those electrodes, films that were deposited in alternate times and the electrodes that were used to deposit films in same times, those films were deposited in the glass substrata, alumina, stainless steel 420, stainless steel 316, silício and steel M2. As the eletros used to deposit films in alternate time as the ones that they were used to deposit in same times, the behavior of the thickness of the film obeyed the curve of the tension with relationship the time of use of the electrode, that is, when the tension was maximum, the thickness of the film was also maximum and when the tension was minimum, the thickness was minimum and in the case where the value of the tension was constant, the thickness of the film tends to be constant. The fine films that were produced they had applications with nano stick, bio-compatibility, cellular growth, inhibition of bacterias, cut tool, metallic leagues, brasagem, pineapple fiber and ornamental. In those films it was investigated the thickness, the adherence and the uniformity characterized by sweeping electronic microscopy. Another technique developed to assist the production and characterization of the films produced in that work was the caloteste. It uses a sphere and abrasive to mark the sample with a cap impression, with that cap form it is possible to calculate the thickness of the film. Through the time of life of the cathode, it was possible to evaluate the rate of waste of its material for the different work conditions. Values of waste rate up to 3,2 x 10-6 g/s were verified. For a distance of the substratum of 11 mm, the deposited film was limited to a circular area of 22 mm diameter mm for high pressures and a circular area of 75 mm for pressure strip. The obtained films presented thickness around 2,1 µm, showing that the discharge of arch of hollow cathode in argon obeys a curve characteristic of the tension with the time of life of the eletrodo. The deposition rate obtained in this system it is of approximately 0,18 µm/min

Síntese e caracterização de catalisadores nanométricos de LaSrNiO4 para aplicação em dessulfurização de tiofeno

The mixed metal oxides constitute an important class of catalytic materials widely investigated in different fields of applications. Studies of rare earth nickelates have been carried by several researchers in order to investigate the structural stability afforded by oxide formed and the existence of catalytic properties at room temperature. So, this study aims synthesize the nanosized catalyst of nickelate of lanthanum doped with strontium (La(1-x)SrxNiO4-d; x = 0,2 and 0,3), through the Pechini method and your characterization for subsequent application in the desulfurization of thiophene reaction. The precursor solutions were calcined at 300ºC/2h for pyrolysis of polyester and later calcinations occurred at temperatures of 500 - 1000°C. The resulting powders were characterized by thermogravimetric analysis (TG / DTG), surface area for adsorption of N2 by BET method, X-ray diffraction (XRD), scanning electron microscopy (HR_SEM) and spectrometry dispersive energy (EDS). The results of XRD had show that the perovskites obtained consist of two phases (LSN and NiO) and from 700ºC have crystalline structure. The results of SEM evidenced the obtainment of nanometric powders. The results of BET show that the powders have surface area within the range used in catalysis (5-50m2/g). The characterization of active sites was performed by reaction of desulfurization of thiophene at room temperature and 200ºC, the relation F/W equal to 0,7 mol h-1mcat -1. The products of the reaction were separated by gas chromatography and identified by the selective detection PFPD sulfur. All samples had presented conversion above 95%

Ventilação e prescrições urbanísticas: uma aplicação simulada para a Orla da Praia do Meio em Natal/RN

This work analyses a study on natural ventilation and its relation to the urban legislation versus the building types in an urban fraction of coastal area of Praia do Meio in the city of Natal/RN, approaching the type or types of land use most appropriate to this limited urban fraction. The objective of this study is to analyse the effects of the present legislation as well as the types of buildings in this area on the natural ventilation. This urban fraction was selected because it is one of the sites from where the wind flows into the city of Natal. This research is based on the hypothesis stating that the reduction on the porosity of the urban soil (decrease in the set back/boundary clearance), and an increase in the form (height of the buildings) rise the level of the ventilation gradient, consequently causing a reduction on the wind speed at the lowest part of the buildings. Three-dimensional computational models were used to produce the modes of occupation allowed in the urban fraction within the area under study. A Computational Fluid Dynamics (CFD) software was also used to analyse the modes of land occupation. Following simulation, a statistical assessment was carried out for validation of the hypothesis. It was concluded that the reduction in the soil porosity as a consequence of the rates that defined the minimum boundary clearance between the building and the boundary of the plot (and consequently the set back), as well as the increase in the building form (height of the buildings) caused a reduction in the wind speed, thus creating heat islands

Estudo dos efeitos da aplicação de um programa de promoção da resiliência e de competências sociais e emocionais com crianças em situação de risco da cidade de Tijuana

Artigo teórico: O presente artigo tem como objetivo permitir uma visão global sobre as circunstâncias que podem influenciar, positiva ou negativamente, a vida das crianças e apresentar programas desenhados para promover o seu correto desenvolvimento, mesmo em casos menos favoráveis. Para isto, são revistos os conceitos mais importantes associados às noções de risco, perigo, proteção e resiliência, sintetizadas as relações que estes estabelecem entre si e abordados quais os principais contextos nos quais o profissional pode intervir. Este trabalho foca-se principalmente nas crianças da cidade de Tijuana, pelo que é realizado um trabalho de comparação de estatísticas oficiais entre Portugal e México (quando aplicável, cingido ao estado da Baja Califórnia) de modo a contextualizar os diferentes perigos e proteções que as respetivas culturas providenciam. Para concluir, são apresentados alguns exemplos de intervenções recentes que visam promover a resiliência através de abordagens distintas e em contextos culturais diversos, de modo a deixar no leitor uma ideia das possibilidades e da importância da intervenção nesta área. Artigo teórico-prático: O presente artigo tem como objetivo avaliar o impacto de uma adaptação do programa “Ultrapassar Dificuldades e Vencer Desafios: Manual de Promoção da Resiliência na Adolescência” numa população de crianças em situação de risco, do 1.º ao 6.º ano de escolaridade, da cidade de Tijuana (Baja California, México). Foram realizadas intervenções com dois grupos de crianças que se encontravam em contexto familiar e com um grupo de crianças em contexto institucional. As sessões realizadas, que adaptaram o programa dando-lhe um enfoque psicomotor, compreenderam a duração total de 20 horas e foram realizadas nas instituições de ensino. A intervenção demonstrou ter alguns efeitos positivos ao nível da auto-perceção de competências relacionadas com a resiliência, bem como um efeito de diminuição de alguns fatores de riscos intra-individuais. Na ótica dos prestadores de cuidados, foram ainda encontrados resultados significativos ao nível da diminuição da hiperatividade, dos problemas de comportamento e do total de dificuldades (avaliados pelo instrumento Strenghts and Difficulties Questionnaire). Este programa apresenta assim resultados encorajadores, num contexto diferente ao que serviu de substrato para o desenho do programa, e reforça a noção de que as competências sociais e emocionais são vitais para o correto desenvolvimento infantil em qualquer cultura.
