Goda relationer – En förutsättning för morgondagens entreprenörer

Thalinsson Ranhagen, Elias, Norstedt, Josefin January 2015 (has links)
I takt med en ökad internationalisering och hårdnad global konkurrens ställs större krav på morgondagens entreprenörer. I Uppsala kommun har den omfattande kapaciteten inom utbildning och forskning uppfattats som ett särskilt viktigt verktyg för att möta dessa utmaningar, varför studiens fokus riktas på hur de entreprenörskapsfrämjande aktörerna som existerar kring Uppsala universitet tillsammans verkar för att skapa förutsättningar för studenter och forskare. Syftet med denna uppsats är således att erhålla en så pass heltäckande bild som möjligt av detta nätverk av relationer för att sedan kunna analysera hur dessa kan vidareutvecklas. För att besvara detta syfte har en kvalitativ fallstudie genomförts, där studien primärt fokuserade på fyra aktörer som ansågs vara särskilt vitala. Studiens resultat visar på att det finns goda möjligheter för vidareutveckling genom bland annat ökade resurs- och aktivitetsutbyten mellan olika aktörer.

As plantas forrageiras, quando bem manejadas se destacam pela alta capacidade produtiva e pela extração de nutrientes do solo. A aplicação de ARA-Graxaria no solo, através da fertirrigação reduz custos com fertilizantes químicos, contudo é essencial o monitoramento dos elementos químicos no solo nos locais onde se faz essa fertirrigação, minimizando riscos de contaminações ambientais. Diante disso, propõe-se avaliar a lixiviação de nutrientes e alteração de propriedades químicas do solo submetido a aplicação de água residuária de graxaria. Foi realizado experimento em colunas de solo plantadas com capim Vaquero, sob um delineamento inteiramente casualizado, com dois tipos de solo e quatro doses de ARA-Graxaria com três repetições. Foram feitas irrigações e simulação de chuvas. O lixiviado gerado foi coletado e analisado em laboratório para determinar nitrato e fósforo total, no solo foi determinado o fósforo e nitrogênio total. Para a forragem foi determinado o parâmetro de massa de forragem. As aplicações de ARA-Graxaria contribuíram com aumento na produção do Capim Vaquero, os teores de nitrato ficaram abaixo do nível crítico de contaminação das águas, evidenciando potencial do uso de ARA-Graxaria em fertirrigação de pastagens. Os teores fósforo total e nitrogênio total no solo e nos lixiviados, de forma geral, não representam riscos para contaminação das águas subsuperficiais. / Agroindustry Wastewater - Graxaria (ARA-Graxaria) is characterized mainly by high levels of nutrients, such as phosphorus and nitrogen, presenting great potential to be used through fertigation. Forage plants, when well managed, are distinguished by their high productive capacity and the extraction of nutrients from the soil. The application of ARA-Graxaria in the soil, through fertigation reduces costs with chemical fertilizers, however it is essential the monitoring of the chemical elements in the soil in the places where this fertirrigation is done, minimizing risks of environmental contaminations. Therefore, it is proposed to evaluate the leaching of nutrients and alteration of chemical properties of the soil submitted to the application of wastewater from grease. An experiment was carried out in soil columns planted with Vaquero grass under a completely randomized design with two soil types and four ARA-Graxaria doses with three replications. Irrigations and simulation of rain were done. The leachate generated was collected and analyzed in the laboratory to determine nitrate and total phosphorus, in the soil was determined the phosphorus and total nitrogen. For forage, the forage mass parameter was determined. The applications of ARA-Graxaria contributed with an increase in the production of Capim Vaquero, the nitrate levels were below the critical level of water contamination, evidencing the potential of the use of ARA-Graxaria in pasture fertirrigation. The total phosphorus and total nitrogen contents in the soil and in the leachates, in general, do not present risks for contamination of subsurface waters.

Phylogeny of the Genus Arachis and its Application to the Evolution of the Major Peanut Allergen Ara h 2

Friend, Sheena Anne 08 September 2010 (has links)
Peanuts (<i>A. hypogaea</i>) are an economically important crop, a source of food allergies and a member of the South American genus <i>Arachis</i>. The eighty species of genus <i>Arachis</i> have been divided into nine sections. The largest, section <i>Arachis</i>, has been further subdivided into three genome groups. The current intuitive understanding of the evolutionary relationships among <i>Arachis</i> is based on morphological, geographic and cytogenetic data, but a comprehensive phylogenetic study for the genus is lacking. A total of 48 species representing all nine sections were used to reconstruct a phylogeny based on sequence information from plastid <i>trn</i>T-<i>trn</i>F and nuclear ITS genomic regions. Phylogenetic analysis resolved section <i>Extranervosae</i> at the base, followed by sections <i>Triseminatae</i> and <i>Caulorrhizae</i>. Two major terminal lineages were recovered. One is comprised of sections <i>Erectoides</i>, <i>Heteranthae</i>, <i>Procumbentes</i>, Rhizomatosae</i>, and <i>Trierectoides</i>, referred to here as group erectoides. The other is comprised of two major clades, arachis I (B genome, D genome, and aneuploid species) and arachis II (A genome species). The phylogenetic trees show that sequence data partially agrees with the relationships described in the monograph; however, some further investigation is necessary to clarify relationships within and among species of the two terminal lineages. In addition, the major allergen Ara h 2 from 12 wild species from across the genus was analyzed for mutations that could potentially produce a hypoallergenic ortholog. It was found that the evolution of the allergen mostly reflected the species phylogenies based on ITS and combined. The majority of substitutions and length variations were concentrated in the loop connecting helices H2 and H3. Section <i>Arachis</i> species tended to have larger H2-H3 loops, while those from other sections had shorter loops. The immunodominant epitopes #6 and #7, located within this loop, tended to contain mutations or were truncated among species outside of section <i>Arachis</i>. Dot immunoblots showed reduced IgE-binding to peptides representing portions of the H2-H3 loop from <i>A. guarantica</i> and <i>A. triseminata</i>. Orthologs from wild species have demonstrated that they could potentially contain variations of the allergen Ara h 2 that could be utilized to develop a safer peanut cultivar. / Ph. D.

Este trabalho apresenta estratégias para análise quantitativa e semiquantitativa por Espectrometria de Fluorescência por Dispersão de Energia de Raios-X (EDXRF) em três situações típicas: a) materiais homogêneos cujos componentes estejam majoritariamente dentro do campo de detecção da técnica (análise quantitativa), b) materiais homogêneos cujos componentes estejam majoritariamente fora do campo de detecção da técnica (análise quantitativa de elementos minoritários detectados) e, c) materiais heterogêneos em camadas sobrepostas cujos componentes de interesse analítico estejam dentro do campo de detecção da técnica (análise semi-quantitativa de elementos detectados). O trabalho descreve os dois espectrômetros utilizados para as medidas, desenvolvidos no laboratório. Para a determinação das áreas dos picos, foi utilizado principalmente o software PyMCA, desenvolvido pelo CERN. Para a determinação de composições, foram utilizados dois softwares de análise quantitativa que utilizam o método dos Parâmetros Fundamentais. O primeiro é o PyMCA, que efetua de forma integrada o ajuste dos picos e a determinação dos teores. O segundo pertence ao pacote Ara-Lihuen, desenvolvido no próprio laboratório, e obtém teores a partir de áreas dos picos. O trabalho apresenta o desenvolvimento de rotinas do Ara-Lihuen que permitem a verificação de etapas intermediárias de cálculo. / This work presents the strategies for quantitative and semi quantitative analyses by Energy Dispersive X-Ray Fluorescence (EDXRF) in three typical situations: a) homogeneous materials whose components are mainly within the field of detection of the technique (quantitative analysis), b) homogenous materials whose components are mostly outside the field of detection of the technique (quantitative analysis of low-content detected elements), and c) heterogeneous materials in superposed layers (semi-quantitative analysis of detected elements). The work describes the two spectrometers used for measurement, developed in the laboratory. For the determination of peak areas, it was used mainly PyMCA software developed by CERN. For the determination of compositions, two quantitative Fundamental- Parameters based (FP) softwares were used. The first is PyMCA, that performs simultaneously the fitting of peaks and the determination the contents. The second belongs to the Ara-Lihuen package, developed in the laboratory, and obtains contents from peak areas. The work presents the development of Ara-Lihuen routines that allow verification of intermediate calculation steps.

The guava crop has important role in the economy, particularly in the family farming in Northeast Brazil especially in the irrigated crops of the Semiarid region. In this crop, Meloidogyne enterolobii, a gall nematode together with the Fusarium solani, cause a complex disease that make unviable several production areas. Besides these problems, the irrigated areas are prone to soil salinity that can also affect the crop. Thus, the search for genotypes in the genus Psidium to be used as resistant rootstock to these stresses or to be used in breeding programs that are devoted to obtain clones that allow the commercial production of guava in the country. Therefore, the aim of this work was to evaluate the reaction of Psidium spp. accessions to different doses of inoculum and also to evaluate the effect of osmoconditioning of Psidium guineense to saline stress. The first trial was carried out in a completely randomized bloc with eight replications. The accessions were inoculated with three inoculum densities (600, 1600 and 2000 eggs/mL) and they were evaluated 135 days after inoculation. The second trial was carried out in a completely randomized block with 25 seeds per replication, using osmoconditionated and not osmoconditionated seeds. It was found genetic variability among and within the accessions to reaction to M. enterolobii. Different inoculum densities can affect, in a differential way, the reproduction rate of the nematode in the root system of each plant and, thus, to make it difficult to identify the reaction of plants to the nematode M. enterolobii. Different electric conductivities affected the seeds regarding all variables evaluated in osmoconditionated and non condicionated seeds. The osmoconditioning can decrease the average and speed of seed germination of P. guineense in conditions of medium salinity level. / A produ??o mundial de alimentos e a produtividade agr?cola t?m sido bastante afetadas por agentes bi?ticos como pragas, insetos, fungos, bact?rias, v?rus e nematoides e tamb?m por fatores abi?ticos como a baixa disponibilidade h?drica, salinidade dos solos dentre outros afetando diversas culturas. A cultura da goiabeira tem importante papel na economia, com destaque para a agricultura familiar no Nordeste brasileiro, especialmente os cultivos irrigados do Semi?rido. Nessa cultura, Meloidogyne enterolobii, o nematoide-das-galhas da goiabeira, juntamente com Fusarium solani, causam doen?a complexa que tem inviabilizado muitas ?reas de produ??o. Al?m desses problemas, as ?reas irrigadas do Semi?rido s?o sujeitas a problemas de salinidade dos solos e que podem atingir tamb?m a cultura da goiabeira. Em vista disso, a busca, dentro do g?nero Psidium, por gen?tipos para uso direto como porta-enxertos resistentes a esses estresses ou para subsidiar programas de melhoramento gen?tico com vistas ? obten??o de clones que viabilizem a produ??o comercial da goiabeira, tornou-se a linha mais atual de alguns programas de pesquisa no Brasil. Assim o presente trabalho teve como objetivo avaliar a rea??o de acessos de Psidium spp. a diferentes densidades de in?culo e avaliar o efeito do osmocondicionamento de sementes de Psidium guineense submetidas ao estresse salino. O primeiro experimento foi realizado em delineamento inteiramente casualizado com oito repeti??es, onde os acessos foram inoculados com tr?s densidades de in?culo 600, 1600 e 2000 ovos/mL e avaliados 135 dias ap?s inocula??o. O segundo experimento foi em delineamento inteiramente casualizado com 25 sementes por repeti??es utilizando sementes osmocondicionadas e n?o osmocondicionadas. Existe variabilidade entre e dentro dos acessos avaliados para rea??o a M. enterolobii. Diferentes densidades de in?culo podem afetar de modo diferenciado, a taxa de reprodu??o do nematoide no sistema radicular de cada planta e, assim, dificultar a identifica??o da rea??o das plantas ao nematoide. M. enterolobii. Diferentes condutividades el?tricas afetaram todas as vari?veis avaliadas em sementes osmocondicionadas e n?o osmocondicionadas. O osmocondicionamento pode diminuir o tempo m?dio e velocidade m?dia de germina??o de sementes de Psidium guineense em condi??es de mediana salinidade.

Were used collecting of floristic and phytosociological facts in two parcels of 20x50m. It was estimated the viability of plantation of enrichment with E. edulis by analysing the growth in two parcels of 20x50m. It was established four classes of size of exposed stirps (C1= up to 0,5m; C2 from 0,5 to 1,5m; C3 from 1,3 to 3,0m and C4 from 3,0m on and with circumference at chest level (CAP) > 15cm). Each parcel was devided in ten subparcels of 10x10m, in which all palm cabbage plantation of (C4 class) had their CAP measurings and exposed etirps height taken.In each subparcel of 10x10m it was allocated a subparcel of 4,0x4,0m, where the individuals of the classes C1,C2 and C3 have had their measurings of diameter of colon, CAP and height of stirps taken. All palm cabbage were identified with aluminium plate printed in low relief and fixed with copper nails.The parcel 1 can be found at the bottom of the region nearby a stream, while the parcel 2 can be found almost 50m above the first parcel. It has been done two measurings in an interval of six months and, at the and of this period, it had been estimated the percentage of survival and of changing of class. The analyses of growth in each sample, and also between one another was done by the non parametric test of Kruskal-Wallis. The fragment was characterized by the index of similarity and diversity, by Margalef with some other seven remainings of Atlantic Forest with different degrees of impactation and distincts successional stages. It was also compared some abiotic characteristics between the fragments. The individuals of C1; C2 and C3 from parcel1 were significantly grown, speaking about the diameter of colon. The individuals of the same classes of parcel 2 have not had an expressive growth, but there have had a significative growth in height of exposed stirps for these classes. The C4 from parcel 1 were grown concerning to the CAP, but those one of the parcel 2 didn?t. Speaking about the height of stirps in both of the parcels, the growth was very significative. The percentage of survival were about 95,8% and 100% in the parcels 1 and 2, respectively. / O presente estudo foi desenvolvido no Santu?rio de Vida Silvestre, Serra da Conc?rdia, Valen?a (RJ), com o objetivo de coletar informa??es que possam subsidiar o manejo e a conserva??o de Euterpe edulis na Floresta Atl?ntica; estudar a flor?stica e a estrutura de uma floresta secund?ria submetida a enriquecimento; avaliar o desenvolvimento de E. edulis em plantio de enriquecimento e confirmar a viabilidade do desenvolvimento da cultura de palmito em remanescentes florestais impactados.

I jakt på tillämpning : Om F.O.V. Fabrics möjligheter att understödja kommersialiseringen av algbatteriforskning

Lindgren, Mattias, Norberg, David January 2011 (has links)
The purpose of this essay is to explore the actor network of a high technology company in the textile industry called F.O.V. Fabrics. The background for doing this is a recent project, which we choose to call the Salt &amp; Paper Battery Group, aiming to commercialize a newly discovered technology – a battery based on cellulose from an alga. We start by examining a range of network theories in order to eventually shape a framework of our own. This framework focuses on the environment defined by actor bonds to three groupings, namely business actors, academic actors and political actors. Two factors appear to be essential in these networks, the creation of an identity and in-depth relations to other actors. Thirteen qualitative interviews were conducted of which the empirical input is based upon. It seems that F.O.V. Fabrics communicates a rather homogenous image to its first hand bonds, which emphasizes the innovativeness, the flexibility and technical knowledge the company possesses. F.O.V. Fabrics’ relations are key priorities and by building long terms relations the company manages to establish a large amount of trust in the actor bonds. The essay concludes by stating that F.O.V. Fabrics, based on the discoveries of this study, is likely to be a valuable player in the Salt &amp; Paper Battery Group.

Despite of the extreme clinical relevance of laboratory examinations, data on hematology and serum biochemistry of this species are scarce. Several factors can interfere with the birds results of hematological and biochemical values, such as age, sex, reproductive period, among others. The study aimed to recognize patterns and to determine haematological and serum biochemical parameters for the species in question, explaining possible variations related to sex, management and method of restraint. In the experiment was used 68 specimens, 33 from a commercial breeding facility and 35 from the live collection of the RIOZOO Foundation. The blood samples were collected by jugular vein, transferred into tubes containing EDTA and other with no anticoagulant. Only the birds of RIOZOO were subjected to a new collection, which occurred 10 minutes after of anesthesia with isoflurane, thus forming a group of 33 animals anesthetized and another 35 unanesthetized. Of each animal were determined trombocyte conts, erythrocyte counts, total and specific leucocyte counts, concentrations of total plasmatic protein, urea, creatinine, uric acid, cholesterol, tryglicer?des, total serum protein, albumin and globulin, and activityes of alkaline phosphatase, aspartate aminotransferase, amylase, lipase, and creatine-kinase enzymes. The results were analyzed by ANOVA and paired T tests. Females had higher trombocitometria. Non-anesthetized animals had a greater total WBC count. Weren?t significant differences between anesthetized males and females. The birds originated from RIOZOO had higher values of PCV, red blood cell count, MCV, eosinophils, basophils, urea, AST and CK, however, lower values of albumin and creatinine. The study revealed that was a significant level of discrepancies between the different groups, allowing the creation of a standard more specific hematologic, according to the individual characteristics of each patient. / Pertencente ?

Kan nätverk konstrueras? : En studie av relationerna och nätverksbyggandet kring Kista Science City AB

Björkman, Martin, Brännström, Joakim January 2009 (has links)
<p>Ett väl fungerande nätverk kan hjälpa företag att förbättra sin produktivitet och skapa möjligheter till affärer. För att utnyttja fördelarna som nätverk kan skapa har Kista Science City AB sedan år 2000 aktivt arbetat med att skapa olika projekt och nätverk, med avsikt att stimulera tillväxt i regionen Kista Science City, framförallt hos de mindre företagen. Syftet med denna uppsats är att beskriva de relationer som företagen inom nätverken kopplade till Kista Science City AB har, med hjälp av ARA-modellen. För att besvara syftet så har en kvalitativ intervjubaserad fallstudie utförts. Uppsatsen visar att det finns störst potential till starka relationer gentemot externa aktörer och att det konstruerade nätverket är begränsat till någon del av de lager som nämns i ARA-modellen.</p>
