National Information Networks and International

We can categorically state that the information is the main ingredient of the culture of a people. Defining information as a set of processed data that are needed, have value and meaning for individuals and for developing countries where data is any fact.The information could also be considered as an international resource indispensable. The scientific and technological development is a consequence of the relevant information is handled. The "heap" is a source of information that libraries must consider and integrate them because they give rise to more information and new technology. The need for improved information systems in recent years, it has become critical because the information data grows in quantity and complexity of organization. Consequently, some libraries have tried to coordinate functions, redistribute resources, identify needs and work together to give easier access to information

Diagnóstico e análise funcional da implementação do Sistema Pyxis no Serviço de Urgência do Hospital Espírito Santo- Évora

Atualmente, existe interesse em determinar o benefício ou contributo do estudo de um determinado tópico para a prática em enfermagem e melhoria do serviço ao utente, o que é percetível na necessidade detetada nessa prática de disponibilizar o medicamento no local adequado, na quantidade exigida e no tempo e gasto mínimos. Neste sentido, verifica-se que o Hospital do Espirito Santo Évora (HESE) adquiriu o sistema Pyxis em 2007 e, até à data, não foi implementado sem se perceber as razões para tal, quer sejam de natureza técnica quer de gestão, o que desperta o interesse no tratamento deste assunto e a relevância do tema. Assim, levanta-se a questão sobre as condições de implementação do Pyxis, o que se traduz num problema, para o qual se procura uma solução com uma metodologia adequada. O presente trabalho tem como objetivo preparar as condições para a implementação do Pyxis. Assim, pretende-se analisar a situação presente e identificar as necessidades de alteração e de ajustamento suportadas nas exigências e requisitos do sistema Pyxis, no que se refere à sua implementação. Em termos metodológicos, para prosseguir o objetivo antes referido, recorre-se ao diagnóstico interno, à descrição do Pyxis, para identificação das condições da sua implementação, à análise funcional e à elaboração do instrumento de inquérito através de questionário, para posterior aplicação. Os resultados obtidos permitem uma verificação dos requisitos e alterações, para a implementação do sistema Pyxis, bem como os benefícios associados a este sistema. Existe a evidência de que o sistema Pyxis é uma nova tecnologia que possibilita ao HESE a diminuição do tempo utilizado pela equipa de saúde no processo logístico de distribuição do medicamento e a melhoraria da qualidade através da diminuição de erro de medicação, sendo fundamental na qualidade dos cuidados de saúde a prestar aos utentes, o que é concordante com o enquadramento teórico efetuado

Effect of pre-treatments and post-treatments on drying products

Freeze drying technology can give good quality attributes of vegetables and fruits in terms of color, nutrition, volume, rehydration kinetics, stability during storage, among others, when compared with solely air dried ones. However, published scientific works showed that treatments applied before and after air dehydration are effective in food attributes, improving its quality. Therefore, the hypothesis of the present thesis was focus in a vast research of scientific work that showed the possibility to apply a pre-treatment and a post-treatment to food products combined with conventional air drying aiming being close, or even better, to the quality that a freeze dried product can give. Such attributes are the enzymatic inactivation, stability during storage, drying and rehydration kinetics, color, nutrition, volume and texture/structure. With regard to pre-treatments, the ones studied along the present work were: water blanching, steam blanching, ultrasound, freezing, high pressure and osmotic dehydration. High electric pulsed field was also studied but the food attributes were not explained on detailed. Basically, water and steam blanching showed to be adequate to inactivate enzymes in order to prevent enzymatic browning and preserve the product quality during long storage periods. With regard to ultrasound pre-treatment the published results pointed that ultrasound is an effective pre-treatment to reduce further drying times, improve rehydration kinetics and color retention. On the other hand, studies showed that ultrasound allow sugars losses and, in some cases, can lead to cell disruption. For freezing pre-treatment an overall conclusion was difficult to draw for some food attributes, since, each fruit or vegetable is unique and freezing comprises a lot of variables. However, for the studied cases, freezing showed to be a pre-treatment able to enhance rehydration kinetics and color attributes. High pressure pre-treatment showed to inactivate enzymes improving storage stability of food and showed to have a positive performance in terms of rehydration. For other attributes, when high pressure technology was applied, the literature showed divergent results according with the crops used. Finally, osmotic dehydration has been widely used in food processing to incorporate a desired salt or sugar present in aqueous solution into the cellular structure of food matrix (improvement of nutrition attribute). Moreover, osmotic dehydration lead to shorter drying times and the impregnation of solutes during osmose allow cellular strengthens of food. In case of post-treatments, puffing and a new technology denominated as instant controlled pressure drop (DIC) were reported in the literature as treatments able to improve diverse Abstract Effect of Pre-treatments and Post-treatments on Drying Products x food attributes. Basically, both technologies are similar where the product is submitted to a high pressure step and the process can make use of different heating mediums such as CO2, steam, air and N2. However, there exist a significant difference related with the final stage of both which can comprise the quality of the final product. On the other hand, puffing and DIC are used to expand cellular tissues improving the volume of food samples, helping in rehydration kinetics as posterior procedure, among others. The effectiveness of such pre and/or post-treatments is dependent on the state of the vegetables and fruits used which are also dependent of its cellular structure, variety, origin, state (fresh, ripe, raw), harvesting conditions, etc. In conclusion, as it was seen in the open literature, the application of pre-treatments and post-treatments coupled with a conventional air dehydration aim to give dehydrated food products with similar quality of freeze dried ones. Along the present Master thesis the experimental data was removed due to confidential reasons of the company Unilever R&D Vlaardingen

Automação da drenagem no teste de produção convencional em tanque cilíndrico

This document aims to improve the quality of the production test in vertical tanks with free water drain pipes, through a device to control the draining system. This proposal consists of an interface detector close to the tank bottle and a control valve on the pipe-drain; they are attached to a remote supervisor system, which will be minimizing the human influence in the conclusion of the test result. And for more consciousness the work shows the importance of the wells production test in the attendance and diagnosis of the productive process, informing the large number of tests executed and problems of the procedure adopted in the field today. There are many possible sources of uncertainty in this kind of test as shown in the experiments realized in the field; the object prototype of this dissertation will be made in the field, based upon the definition of parameters and characteristics of the devices proposal. For a better definition of the draining process the action results of the assessment test are shown, especially changed some for the understand ing of the real process. It shows the proposal details and the configuration that will be used in the tank of Monte Alegre s field Production Station, explaining the interface detector kind and the control system. It is the base to a pilot project now in development, named as the new project classified in the status of the new technology and production improvement of PETROBRAS in Rio Grande do Norte and Ceará. This dissertation concludes that the automation of the conventional test with the draining system will bring benefits both economically as metrologically, because it reduces the uncertainty of the test procedures with free water draining, and also decreases the number of tests with problems

Oligodeoxynucleotide synthesis using protecting groups and a linker cleavable under non-nucleophilic conditions

Oligodeoxynucleotides (ODNs) containing latent electrophilic groups can be highly useful in antisense drug development and many other applications such as chemical biology and medicine, where covalent cross-linking of ODNs with mRNA, protein and ODN is required. However, such ODN analogues cannot be synthesized using traditional technologies due to the strongly nucleophilic conditions used in traditional deprotection/cleavage process. To solve this long lasting and highly challenging problem in nucleic acid chemistry, I used the 1,3-dithian-2-yl-methoxycarbonyl (Dmoc) function to protect the exo-amino groups on the nucleobases dA, dC and dG, and to design the linker between the nascent ODN and solid support. These protecting groups and linker are completely stable under all ODN synthesis conditions, but can be readily cleaved under non-nucleophilic and nearly neutral conditions. As a result, the new ODN synthesis technology is universally useful for the synthesis of electrophilic ODNs. The dissertation is mainly comprised of two portions. In the first portion, the development of the Dmoc-based linker for ODN synthesis will be described. The construction of the dT-Dmoc-linker required a total of seven steps to synthesize. The linker was then anchored to the solid support―controlled pore glass (CPG). In the second portion, the syntheses of Dmoc-protected phosphoramidites ODN synthesis monomers including Dmoc-dC-amidite, Dmoc-dA-amidite, Dmoc-dG-amidite are described. The protection of dC and dA with 1,3-dithian-2-yl-methyl 4-nitrophenyl carbonate proceeded smoothly giving Dmoc-dC and Dmoc-dA in good yields. However, when the same acylation procedure was applied for the synthesis of Dmoc-dG, very low yield was obtained. This problem was later solved using a highly innovative and environmentally benign procedure, which is expected to be widely useful for the acylation of the exo-amino groups on nucleoside bases. The reactions to convert the Dmoc-protected nucleosides to phosphoramidite monomers proceeded smoothly with high yields. Using the Dmoc phosphoramidite monomers dA, dC, dG and the commercially available dT, and the Dmoc linker, four ODN sequences were synthesized. In all cases, excellent coupling yields were obtained. ODN deprotection/cleavage was achieved by using non-nucleophilic oxidative conditions. The new technology is predicted to be universally useful for the synthesis of ODNs containing one or more electrophilic functionalities.

POPLAR GENE EXPRESSION DATA ANALYSIS PIPELINES

Analyzing large-scale gene expression data is a labor-intensive and time-consuming process. To make data analysis easier, we developed a set of pipelines for rapid processing and analysis poplar gene expression data for knowledge discovery. Of all pipelines developed, differentially expressed genes (DEGs) pipeline is the one designed to identify biologically important genes that are differentially expressed in one of multiple time points for conditions. Pathway analysis pipeline was designed to identify the differentially expression metabolic pathways. Protein domain enrichment pipeline can identify the enriched protein domains present in the DEGs. Finally, Gene Ontology (GO) enrichment analysis pipeline was developed to identify the enriched GO terms in the DEGs. Our pipeline tools can analyze both microarray gene data and high-throughput gene data. These two types of data are obtained by two different technologies. A microarray technology is to measure gene expression levels via microarray chips, a collection of microscopic DNA spots attached to a solid (glass) surface, whereas high throughput sequencing, also called as the next-generation sequencing, is a new technology to measure gene expression levels by directly sequencing mRNAs, and obtaining each mRNA’s copy numbers in cells or tissues. We also developed a web portal (http://sys.bio.mtu.edu/) to make all pipelines available to public to facilitate users to analyze their gene expression data. In addition to the analyses mentioned above, it can also perform GO hierarchy analysis, i.e. construct GO trees using a list of GO terms as an input.

Apprendre avec la technologie : l'impact sur l'enseignement et l'apprentissage de l’utilisation de la technologie numérique (SMARTBOARD) dans les classes

This research was devoted to gaining information on teachers? use of technology, specifically SMARTBOARD technology, for teaching and promoting learning in the classroom. Research has suggested that use of technology can enhance learning and classroom practices. This has resulted in administrators encouraging the use of SMARTBOARDS, installing them in classrooms and providing training and support for teachers to use this technology. Adoption of new technology, however, is not simple. It is even more challenging because making the best use of new technologies requires more than training; it requires a paradigm shift in teachers? pedagogical approach. Thus, while it may be reasonable to believe that all we need to do is show teachers the benefits of using the SMARTBOARD; research tells us that changing paradigms is difficult for a variety of reasons. This research had two main objectives. First, to discover what factors might positively or negatively affect teachers? decisions to take up this technology. Second, to investigate how the SMARTBOARD is used by teachers who have embraced it and how this impacts participation in classrooms. The project was divided into two parts; the first was a survey research (Part 1), and the second was an ethnographic study (Part 2). A thirty-nine item questionnaire was designed to obtain information on teachers? use of technology and the SMARTBOARD. The questionnaire was distributed to fifty teachers at two EMSB schools: James Lyng Adult Centre (JLAC) and the High School of Montreal (HSM). Part 2 was an ethnographic qualitative study of two classes (Class A, Class B) at JLAC. Class A was taught by a male teacher, an early-adopter of technology and a high-level user of the SMARTBOARD; Class B was taught by a female teacher who was more traditional and a low-level user. These teachers were selected because they had similar years of experience and general competence in their subject matter but differed in their use of the technology. The enrollment in Class A and Class B were twenty-three and twenty-four adult students, respectively. Each class was observed for 90 minutes on three consecutive days in April 2010. Data collection consisted of videotapes of the entire period, and observational field notes with a graphical recording of participatory actions. Information from the graphical recording was converted to sociograms, a graphic representation of social links among individuals involved in joint action. The sociogram data was tabulated as quantified data. The survey results suggest that although most teachers are interested in and use some form of technology in their teaching, there is a tendency for factors of gender and years of experience to influence the use of and opinions on using technology. A Chi Square analysis of the data revealed (a) a significant difference (2 = 6.031, p < .049) for gender in that male teachers are more likely to be interested in the latest pedagogic innovation compared to female teachers; and, (b) a significant difference for years of experience (2 = 10.945, p < .004), showing that teachers with ?6 years experience were more likely to use the SMARTBOARD, compared to those with more experience (>6 years). All other items from the survey data produced no statistical difference. General trends show that (a) male teachers are more willing to say yes to using the SMARTBOARD compared to female teachers, and (b) teachers with less teaching experience were more likely to have positive opinions about using the SMARTBOARD compared to teachers with more experience. The ethnographic study results showed differences in students? response patterns in the two classrooms. Even though both teachers are experienced and competent, Teacher A elicited more participation from his students than Teacher B. This was so partly because he used the SMARTBOARD to present visual materials that the students could easily respond to. By comparison, Teacher B used traditional media or methods to present most of her course material. While these methods also used visual materials, students were not able to easily relate to these smaller, static images and did not readily engage with the material. This research demonstrates a generally positive attitude by teachers towards use of the SMARTBOARD and a generally positive role of this technology in enhancing students? learning and engagement in the classroom. However, there are many issues related to the SMARTBOARD use that still need to be examined. A particular point is whether teachers feel adequately trained to integrate SMARTBOARD technology into their curricula. And, whether the gender difference revealed is related to other factors like a need for more support, other responsibilities, or a general sense of anxiety when it comes to technology. Greater opportunity for training and ongoing support may be one way to increase teacher use of the SMARTBOARD; particularly for teachers with more experience (>6 years) and possibly also for female teachers.

Grounded Media: Expanding the Scope of Ecological Art Practices Within New Media Arts Culture

‘Grounded Media’ is a form of art practice focused around the understanding that our ecological crisis is also a cultural crisis, perpetuated by our sense of separation from the material and immaterial ecologies upon which we depend. This misunderstanding of relationships manifests not only as environmental breakdown, but also in the hemorrhaging of our social fabric. ‘Grounded Media’ is consistent with an approach to media art making that I name ‘ecosophical’ and ‘praxis-led’ – which seeks through a range of strategies, to draw attention to the integrity, diversity and efficacy of the biophysical, social and electronic environments of which we are an integral part. It undertakes this through particular choices of location, interaction design,participative strategies and performative direction. This form of working emerged out of the production of two major projects, Grounded Light [8] and Shifting Intimacies [9] and is evident in a recent prototypical wearable art project called In_Step [6]. The following analysis and reflections will assist in promoting new, sustainable roles for media artists who are similarly interested in attuning their practices.
