Análise do processo de gestão de projetos de escritórios de design de Porto Alegre/RS focalizando as áreas de conhecimento do PMBOK

A forma pela qual a gestao de projetos e conduzida em uma empresa pode auxiliar para sua consolidacao no mercado. Existem diversos casos de obtencao de resultados positivos com a melhoria desse processo, porem, na area do Design, esses casos sao poucos. Isso e justificado pela falta de conhecimento acerca da importância do Design como elemento estrategico de posicionamento no mercado. Alem disso, verifica-se que, algumas vezes, o designer desconhece formas de melhor gerir sua empresa. Sob essas condicoes, foi realizada uma pesquisa sobre a forma pela qual empresas prestadoras de servico de Design de Porto Alegre/RS desenvolvem seus processos de gestao de projetos, buscando contribuir com o aprimoramento dos processos da gestao de projetos dessas empresas. Para a realizacao da pesquisa, foram realizados estudos de caso em empresas de Design das areas de desenvolvimento de produto, design de ambientes, embalagens, webdesign e design grafico. Optou-se por utilizar as praticas das areas de conhecimento da gestao de projetos do PMBOK (2004) como objetos de comparacao, uma vez que essa referencia e reconhecida como util pela academia e no meio empresarial. Como resultado, verificou-se que as empresas estudadas possuem praticas distintas, nem sempre formalizadas, em seus processos de gestao de projetos. Palavras-chave: Gestao de Projetos.

There are many cases in the literature detailing the positive results achieved via improvements in the project management process. Nonetheless, in the Design area, such examples are less frequent. First, this could be justified when one notices that many companies are not aware of the strategic role played by design. Second, there is a cultural element associated to how the designer manages his projects or his company. Under the conditions presented herein, a research was conducted about how design firms develop their project management processes. The study involved design companies in Porto Alegre/RS. It aimed at improving project management processes; characterizing, analyzing them, as well as proposing positive modifications in the processes. The research included case studies in design companies, in the following areas: product development, environment design, packaging, web design, and graphical design. The project management practices contained in the PMBOK (2004) were selected and used as reference, since they are widely recognized academically and professionally. As a result, it became clear that the observed companies displayed distinct practices, not always formalized, in their project management processes. Keywords: Project Management. Design Management.

Artemis Is a Phosphorylation Target of ATM and ATR and Is Involved in the G2/M DNA Damage Checkpoint Response

ABSTRACT Mutations in Artemis in both humans and mice result in severe combined immunodeficiency due to a defect in V(D)J recombination. In addition, Artemis mutants are radiosensitive and chromosomally unstable, which has been attributed to a defect in nonhomologous end joining (NHEJ). We show here, however, that Artemis-depleted cell extracts are not defective in NHEJ and that Artemis-deficient cells have normal repair kinetics of double-strand breaks after exposure to ionizing radiation (IR). Artemis is shown, however, to interact with known cell cycle checkpoint proteins and to be a phosphorylation target of the checkpoint kinase ATM or ATR after exposure of cells to IR or UV irradiation, respectively. Consistent with these findings, our results also show that Artemis is required for the maintenance of a normal DNA damage-induced G2/M cell cycle arrest. Artemis does not appear, however, to act either upstream or downstream of checkpoint kinase Chk1 or Chk2. These results define Artemis as having a checkpoint function and suggest that the radiosensitivity and chromosomal instability of Artemis-deficient cells may be due to defects in cell cycle responses after DNA damage.
The Role of the Anterior Attention System in Semantic Processing of both Foveal and Parafoveal Words

This research takes advantage of combined cognitive and anatomical studies to ask whether attention is necessary for high-level word processing to occur. In Experiment 1 we used a lexical decision task in which two prime words, one in the fovea and the other in the parafovea, appeared simultaneously for 150 msec, followed by a foveal target (word/nonword). Target words were semantically related either to the foveal or to the parafoveal word, or unrelated to them. In one block of trials subjects were also required to perform an auditory shadowing task. From PET studies we know that shadowing activates the anterior cingulate cortex, involved in selective attention. If the anterior attention system is always involved in semantic processing, shadowing should reduce semantic priming obtained from both foveal and parafoveal words. In contrast, if semantic priming by parafoveal words is independent of activation in that attention area, priming will not be affected by shadowing. Our results supported the latter hypothesis. A large priming effect arose from foveal primes, which was reduced by shadowing. For parafoveal primes a smaller priming effect arose, which was not affected by shadowing. In Experiment 2 prime words were masked. Semantic priming was reliable for both foveal and parafoveal words but there were then no differences between them. Most important, the size of priming was similar to that obtained from parafoveal words in Experiment 1. We conclude that the anterior attention system increases the potency of processing of consciously perceived stimuli, but there is a component of semantic priming that occurs without both focusing of attention and awareness, involving different cerebral areas to those involved in attention to language.
Effect of ammonia concentration on the composition, hydrolytic activity and nitrogen metabolism of the microbial flora of the rumen.

The mean NH3 concentration in the rumen of sheep fed whole barley (0d8 kg/d) by continuous feeders was increased from 6d1 to 13d4 HIM by supplementing the feed with urea (30 g/kg). This change caused a 90% increase in the rate of degradation of rolled barley, and smaller increases in the rates of degradation of protein and plant fibre in the rumen. The total viable count and numbers of pectinolytic bacteria in rumen fluid increased with the urea supplement. Enzyme studies indicated that NAD-linked glutamate dehydrogenase was the main pathway of NH3 assimilation by rumen bacteria at both NH3 concentrations. Glutamate was the main free amino acid found in the rumen at low NH3 but, despite the low activity of alanine dehydrogenase and glutamate-pyruvate aminotransferase, alanine was the principal amino acid at high NH3 concentrations. Hydrolytic rumen bacteria may require the higher NH3 concentration either for effective NH3 assimilation by an unknown mechanism involving alanine or for full expression of enzyme activity.
The Thermodynamic Characterization of Wetting by Submitting a Sessile Drop to Microgravity

A new method, the sessile drop accelerometry (SDACC) for the study and measurement of the interfacial energies of solid-liquid-gas systems, is tested and discussed in this study. The laboratory instrument and technique –a combination of a drop shape analyzer with high-speed camera and a laboratory drop towerand the evaluation algorithms, were designed to calculate the interfacial energies as a function of the geometrical changes of a sessile droplet shape due to the effect of “switching off” gravity during the experiment. The method bases on the thermodynamic equilibrium of the system interfaces and not on the balance of bi-dimensional tensions on the solid-liquid-gas contour line. A comparison of the mathematical model that supports the method with the widely accepted Young`s equation is discussed in this study.
CRM Implementation in Lebanese SMEs: Descriptive Analysis

SMEs and entrepreneurship are the foundational drivers for the creation of economic value, source of innovation, employment and wealth generation across the globe (Inventis, 2014). The beauty service industry is one of the most flourishing industries in contemporary Beirut, the capital of Lebanon, as versatile demands from men and women have catered to this uplifting growth. A national scandal, however, lead to the suspension of several beauty centers, and conveyed a challenge for competitive small-medium enterprises (SME) to sustain relationships with customers over the long-run. The aim of this study was to discover the extent to which CRM is implemented in SMEs, using the case of beauty centers in Beirut, Lebanon. The study employed a quantitative approach where data was collected by means of a questionnaire, from a sample of 103 customers. Four variables, as components of CRM, were measured in this study. Results of the statistical analysis found that SMEs in Lebanon implement CRM strategy to a good extent. This research provides recommendations for strategically improving relationship-oriented practices in Lebanese SMEs, particularly in the beauty sector.
Houda LABIOD A BCH Error Recovery Scheme for Adaptive Error Control in Wireless Networks 2 impairment

In this paper, we evaluate the performance of an adaptive error correction scheme for Wireless ATM Networks (WATM). This scheme attempts to minimize the system throughput in order to satisfy the user defined Quality of Service (QoS) constraints. Indeed, error control for high speed wireless ATM networks is an important research topic even wireless communication channels are highly affected by unpredictable factors like co-channel interference, adjacent channel interference, propagation path loss and multipath fading. We propose an intelligentagent architecture to implement our mechanism “A-BCHFEC” (Adaptive BCH FEC Scheme) for Rayleigh fading environment. Intelligent agents are distributed over all system entities. In the latter, base station agents cooperate with other agents to choose the appropriate BCH coding scheme related to a specific level of Signal-toNoise-Ratio (SNR). Finally, we illustrate our implementation by some simulation results from a cellular system. These results show that the adaptive scheme using BCH codes improves significantly the performance of WATM networks.
CAN YOU HEAR ME NOW? AN INNOVATIVE EXPERIENTIAL LEARNING MODULE TO PREPARE TOMORROW’S INSIDE SALESPEOPLE

Inside sales is a fast-growing sales profession, with the increase in inside sales positions skyrocketing beyond outside sales positions. Unfortunately, instructors lack the resources to adequately prepare students for inside sales careers. This study provides an innovative, short-term module that introduces the topic of inside sales, differentiates it from outside sales, and prepares students for an inside sales career through a novel role-play activity. Findings indicate that students experienced actual and perceived learning via the role play. Further, students who experienced the module were more likely to view inside sales as a desirable career than those who did not.
Réalité évoquée, des rêves aux simulations : un cadre conceptuel de la réalité au regard de la présence

Dans cette recherche, nous presentons le concept de «Realite Evoquee» (« Evoked Reality ») afin d'essayer de relier differentes notions entourant la presence et la realite au sein d'un cadre commun. Nous introduisons et illustrons le concept en tant que « illusion de la realite » (Realite Evoquee) qui evoque un « sentiment de presence » (Presence Evoquee) dans nos esprits. Nous distinguons les concepts de « Realite Media-Evoquee » et « Realite Auto-Evoquee » et nous les definissons clairement. Le concept de « Realite Evoquee » nous permet d'introduire un modele tripolaire de la realite, qui remet en cause le modele classique des deux poles. Nous presentons egalement un modele graphique appele « Reality-Presence Map » (Carte Realite-Presence) qui nous permet de localiser et d'analyser toutes les experiences cognitives concernant la presence et la realite. Nous explorons egalement les qualia et la subjectivite de nos experiences de Realite Evoquee. Deux experiences ont ete realisees : l'une dans le domaine de la Realite Media-Evoquee et l'autre dans celui de l'Auto-Evoquee. Les experiences nous ont permis de valider nos hypotheses et de realiser que nos recherches empiriques pouvaient encore etre poussees plus loin encore. Enfin, nous illustrons les differentes implications et nous examinons les applications et les utilisations possibles de notre concept, en particulier dans le domaine de la recherche sur la presence. En outre, nous proposons d'etendre la recherche sur la presence au-dela du domaine de la realite virtuelle et des moyens de communication et de l'etudier dans une perspective plus large que celle des sciences cognitives. Nous sommes convaincus que ce concept de Realite Evoquee et le modele propose peuvent avoir des applications significatives dans l'etude de la presence et dans l'exploration des possibilites qui depassent la realite virtuelle.
A Disciplined Approach to Office Analysis

To define office requirements, the authors propose a disciplined language in which a good portion of conventionality and known and concrete concepts are associated with a minimum formalism. The language can be used in analyzing an office for the purpose of designing a computer-based office support system. Given the language, the designer can organize information obtained by people working in the office and state the office requirements that will be the basis for developing a suitable system. The features of the language are illustrated and its morphology and syntax are explained. >
More expressive planning graph extension

The most of the real world problems have characteristics that can not be handled like pure propositional expressions. Many classical planners have been extended to deal with more expressive problems which require features like temporal actions, numeric functions, conditional effects, . etc. Extensions have been made to planners like (D. and D., 1999), MetricFF02, (Do and Kambhampati, 2001), which use the planning graph as their base structure. However, each of these extensions deals with the one or the other of the features required for more expressive planning problems without being able to integrate all or at least an important combination of these features. In this paper, we propose an extension to the planning graph structure to deal with more expressive planning problems that can contain real word data characteristics, such as: symbolic, temporal and
The Role of the Methionines and Histidines in the Transmembrane Domain of Mammalian Copper Transporter 1 in the Cellular Accumulation of Cisplatin

Mammalian copper transporter 1 (CTR1) is a high-affinity copper influx transporter that also mediates the uptake of platinum-containing chemotherapeutic agents including cisplatin (cDDP). Methionines 150, 154, and histidine 139 have been proposed to form a series of stacked rings in the pore formed by the CTR1 homotrimer, each of which is required for maximal copper transport. To examine the mechanism by which hCTR1 also transports cDDP, variant forms of hCTR1 in which methionines 150 and 154 were converted to isoleucines or in which histidine 139 was converted to alanine were re-expressed in cells in which both alleles of CTR1 had been knocked out. Each of these conversions disabled copper transport and increased cellular resistance to the cytotoxic effect of copper. In contrast, conversion of the methionines increased the uptake and cytotoxicity of cDDP well above that attained with wild-type hCTR1. Conversion of His139 to alanine did not impair cDDP uptake and actually enhanced cytotoxicity. Thus, although Met150 and Met154 facilitate the movement of copper through the pore, they serve to obstruct the passage of cDDP. None of the modifications altered the ability of cDDP to trigger the degradation of hCTR1, indicating that cDDP must interact with hCTR1 at other sites as well. Although both copper and cDDP may rely on a series of transchelation reactions to pass through the hCTR1 trimeric complex, the details of the molecular interactions must be different, which provides a potential basis for selective pharmacological modulation of copper versus cDDP cytotoxicity.

Interactive molecular dynamics

Physics students now have access to interactive molecular dynamics simulations that can model and animate the motions of hundreds of particles, such as noble gas atoms, that attract each other weakly at short distances but repel strongly when pressed together. Using these simulations, students can develop an understanding of forces and motions at the molecular scale, nonideal fluids, phases of matter, thermal equilibrium, nonequilibrium states, the Boltzmann distribution, the arrow of time, and much more. This article summarizes the basic features and capabilities of such a simulation, presents a variety of student exercises using it at the introductory and intermediate levels, and describes some enhancements that can further extend its uses. A working simulation code, in HTML5 and JavaScript for running within any modern Web browser, is provided as an online supplement.
Obtaining nanoimprint template gratings with 10 nm half-pitch by atomic layer deposition enabled spacer double patterning

A strategy for fabricating nanoimprint templates with sub-10 nm line and 20 nm pitch gratings is demonstrated, by combining electron beam lithography and atomic layer deposition. This is achieved through pitch division using a spacer double-patterning technique. The nanostructures are then replicated using step-and-repeat ultra-violet assisted nanoimprint lithography.
What entropy tells about man-made structures

This paper explores the challenge of optimally categorizing regions for man-made environment. We propose using the histogram of oriented gradients (HOG) features for characterizing image regions, and propose an algorithm based on the entropy of HOG to select relevant regions. We also propose a region sensitive feature selection algorithm for image registration. The algorithms are applied to several mobile applications, including image search and photo registration for panorama on mobile phones. We demonstrate the effectiveness of our approach by experimental results on a large dataset.
A Systematic Approach to Gain Suppression using Eigenstructure Assignment

Eigenstructure assignment is an excellent method for incorporating classical specifications on damping, settling time, and mode decoupling into a modern multivariable control framework. Andry et. al.[1] proposed to eliminate certain gains in the output feedback gain matrix which is called gain suppression. This approach may yeild a simpler and more reliable controller with only a small effect on performance. Reference lpresents amethod for computing the remaining active gains once the entries of the gain matrix which are to be suppressed to zero are chosen. However, the choice of gains to be constrained to zero is determined by computer simulation of many different feedback structures. It would be more desirable to obtain
Combining array‐based approaches for the identification of candidate tumor suppressor loci in mature lymphoid neoplasms

Tumor suppressor gene (TSG) inactivation by chromosomal deletions and/or mutations is a well‐characterized genetic alteration in lymphomas. Array‐based technologies have greatly increased the detection and characterization of chromosomal imbalances and regions with loss of heterozygosity (LOH), leading to the identification of a number of novel candidate TSG loci. In addition, microarray platforms for studying DNA methylation and histone modifications enable identifying epigenetic changes affecting gene expression of TSG. Combining these microarray technologies with gene expression profiling is a promising strategy to discover novel TSG in regions targeted by genetic or epigenetic alterations. In this review we present an outline of methodological aspects of the various microarray technologies, and discuss their potentials and restrictions. Furthermore, we survey research findings derived from these high‐throughput techniques, which are allowing a deeper insight into the mechanisms of lymphomagenesis.
TVAC based PSO for solving Economic and Environmental Dispatch considering security constraint

This paper presents Multi Objective Optimization for Economic and Environmental Dispatch (EED) problem considering security constraint described by Voltage Profile Index (VPI). The fuzzy set theory is used for the modeling of uncertainties about objective functions in the practical environment of poorly defined data. In the beginning, each objective function is optimized independently with an extraction of minimal and maximal values for each one. The membership functions are defined, fuzzy set theory is used to formulate the new standard nonlinear problem and max-min operator for maximizing the Degree of Satisfaction (DS) of all membership functions and to get Pareto solution. Conventional Particle Swarm Optimization (PSO) and Time Varying Acceleration Coefficients (TVAC) based PSO methods are used to solve the problem and demonstrating the effectiveness and capability of the second method over the first one. For both algorithms, IEEE 30 bus test system is applied to verify objectives cited above.
