title: Efficient medical image access in diagnostic environments with limited resources

description: Abstract Introduction A medical application running outside the workstation environment has to deal with several constraints, such as reduced available memory and low network bandwidth. The aim of this paper is to present an approach to optimize the data flow for fast image transfer and visualization on mobile devices and remote stationary devices. Methods We use a combination of client- and server-side procedures to reduce the amount of information transferred by the application. Our approach was implemented on top of a commercial PACS and evaluated through user experiments with specialists in typical diagnosis tasks. The quality of the system outcome was measured in relation to the accumulated amount of network data transference and the amount of memory used in the host device. Besides, the system's quality of use (usability) was measured through participants’ feedback. Results Contrarily to previous approaches, ours keeps the application within the memory constraints, minimizing data transferring whenever possible, allowing the application to run on a variety of devices. Moreover, it does that without sacrificing the user experience. Experimental data point that over 90% of the users did not notice any delays or degraded image quality, and when they did, they did not impact on the clinical decisions. Conclusion The combined activities and orchestration of our methods allow the image viewer to run on resource-constrained environments, such as those with low network bandwidth or little available memory. These results demonstrate the ability to explore the use of mobile devices as a support tool in the medical workflow.

title: Septic arthritis of the TMJ: a case report

description: ABSTRACT Septic arthritis of the temporomandibular joint (TMJ) is an uncommon condition; thus, reports in the specialized literature are still scarce. The TMJ may be affected by extension of a local infectious process, by post-traumatic hematoma, or secondarily, by hematogenous spread. Septic arthritis is more common in the large joints, with the knee and hip most frequently affected. It is characterized by insidious onset and a marked inflammatory process, and is monoarticular in 80% of cases. The present report describes the case of a 6-year-old boy with a history of rheumatoid arthritis who presented with pain, swelling, and redness in the right TMJ region, as well as limited jaw opening, closure, and lateral excursion bilaterally. The differential diagnosis and treatment of this rare clinical entity are described. Aspects concerning antibiotic therapy and imaging studies are also addressed.

title: Effect of Varying Design Options on the Transient Behavior of a Hybrid Rocket Motor

description: ABSTRACT: Hybrid rockets provide compelling features for use in atmospheric and space rocket propulsion. One of the prominent applications of hybrid rockets which foster on its characteristics is the propulsion of micro air launch vehicles. In this paper, a set of design options of a hybrid rocket motor is evaluated for propulsion of micro air launch vehicles. In order to evaluate the various design options of a hybrid rocket, we developed design and performance simulation codes. A simulation code is based on a legacy interior ballistic model. MATLAB® environment was used to develop the design and performance analysis codes and to visualize the temporal variation of performance characteristics and grain geometry during burning. We employ the developed codes to assess the replacement of solid rocket motors which are typically used in Air Launch Vehicles by hybrid rocket motors. A typical Micro Air Launch Vehicle mission to launch a 20-kg payload into a 400-km circular polar orbit is assumed. The results show that a hybrid rocket is a suitable candidate for micro air launch vehicles. The performance is improved in terms of specific impulse and thrust with smaller size in the same mission. Several design parameters of hybrid rocket motors were also evaluated and analyzed, including different fuel port geometry, type of fuels and oxidizers, number of ports, nozzle design and initial mass flux. These design parameters bring a significant effect on hybrid rocket performance and size.

title: Evaluation of user satisfaction from the Carta SUS, in Rio Grande do Norte, Brazil

description: ABSTRACT The purpose of this study was to analyze user satisfaction and the characterization of the hospital and outpatient services of the Unified Health System (SUS). A cross-sectional analytical study was performed using user data that responded to the Carta SUS instrument between 2012 and 2013, in the state of Rio Grande do Norte, in which the quality of the physical structure, the health team and the treatment offered. Of the 17.333 users who answered the SUS Charter in the period studied, 62.3% were women and 62.4% were over 40 years old. Most of the attendances (56.8%) were held in the capital and in public services (70.3%). The users were satisfied with the services, with a percentage that ranged from 79 to 90%, according to the health regions. Men and people over 60 evaluated services more positively; the high complexity and the services of the capital had better results (p≤0.001), as well as the private units. The importance of health evaluation and the relevance of analyzing, disseminating and giving continuity to the SUS Charter instrument is emphasized, with a view to subsidizing further studies and reflections on the quality of services.

title: Experimental results for guidance and design criteria of horizontal end-dumping type river closure

description: ABSTRACT The river diversion involves the construction of cofferdams when dumped material is exposed at high velocities, which may cause the drag of blocks. Classical equations relate the mean rock diameter to the drop of water surface between the upstream and downstream. Results of 283 experimental tests performed in hydraulic models allowed the definition of a relationship between water surface drop and mean diameter in the limit condition of stability. The result obtained was d = 0.33×ΔH, consistent with classical equations and validating their applicability, suggesting it use for design and analysis.

title: Hazardous housing attachment scale: construction and evidence based on content

description: ABSTRACT The research aimed to build a hazardous housing attachment scale and sought evidence of validity based on the content of the items. For its construction, it used the tripartite model of Scannell and Gifford, who understand that attachment to a place is formed by the factors: person, place, and psychological process. Sixty-eight self-reported statements were elaborated on a five-point Likert scale, where the analysis of judges by seven postgraduates of the field and the semantic analysis by thirty people residing in an area susceptible to flooding and/or landslides. For the analysis of judges, we used the Content Validity Ratio where 36 items were considered as relevant (RVC = 1.0) and 32 as irrelevant (RVC = -0.42 to -0.14), which were excluded. In the semantic analysis, 35 items were evaluated as clear and in one the writing was altered. Three were excluded because they did not represent population characteristics or tend the result. The preliminary scale obtained 33 items with evidence of validity based on content items. Weaknesses were identified in the tripartite theoretical model and used to understand the construct in a way that it requires its empirical testing. Studies are suggested that seek other evidence of validity and evidence of accuracy.

title: New formula proposal for the determination of variable speed pumps efficiency

description: ABSTRACT The use of pumps which work with variable rotation speed consists of an appropriate tactics for reduction of energy costs in the pump systems. In case of change in speed, the pump starts to work in a new flow pattern, head and efficiency values. Two empirical formulas can be found in the literature in order to estimate the final efficiency of a pump in this situation. This article aims at assessing the accuracy of these formulas and, next, to present a new proposal for the efficiency estimate in the new operating conditions. 50 pumps have been chosen and, for each of them, the above-mentioned formulas have been assessed in three procedures of speed reduction. The analysis of these equations’ accuracy has been accomplished by means of the comparison between the efficiencies estimated by them with the efficiencies calculated with the aid of the affinity laws. The results indicated that, in 95 of the 150 analysis procedures accomplished, the formula proposed presented estimates which have shown to be more precise than the other two formulas. It has also been possible to verify that the average of error detected through the procedure of the new formula (1.60%) has been lower than the average of the other two (1.93% and 2.22%). In light of this fact, the use of the equation here presented is considered advantageous since, from their more accurate efficiency estimates, the calculations for power and energy are also more precise.

title: Satisfaction of users assisted in four regional dental specialties centers of Ceará, Brazil

description: ABSTRACT The objective of this research was to evaluate the satisfaction of users assisted in Regional Dental Specialties Centers (CEO-R) of Ceará, Brazil. It is a descriptive cross-sectional study. In those establishments, 518 users were interviewed, using the Oral Health Services Quality Assessment Questionnaire (QASSaB) as a research tool. The data collected were analyzed by Pearson’s Chi-square test. Prevalence: female (67.8%), low schooling (67.8%) and income (63.9%). Regarding accessibility issues, only the waiting time at reception (83.5%) was considered positive, with unfavorable highlight to the specialty orthodontics in the time to obtain a vacancy. The other dimensions analyzed were positively evaluated by the study. Relating the service units surveyed, there were statistically significant differences (p&lt;0.05) in the satisfaction of users for most of the dimensions analyzed, except for the ‘third-party aid’ questionnaire and the ‘resolution / satisfaction’ with dental treatment (p&gt;0.05). It was concluded that the level of satisfaction of the users participating in the research was generally positive, with accessibility being an impacting problem in the system, which should be rethought in order to reduce any dissatisfaction among users who require the specialized dental service of the regional network health care.

title: RESIDUAL EFFECTS OF NITROGEN FERTILIZER WITH POLYMER-COATED UREA IN A CORN CROP

description: ABSTRACT The use of nitrogenous fertilizer coated by polymers may reduce losses caused by volatilization, thus exposing this element to plants for a longer period of time. The objective of this work was to evaluate the residual effects of nitrogen in the form of conventional urea and urea coated by polymers in the production components and grain productivity of the first and second corn crops. The experiment was conducted in Selvíria - MS in a clay-type Oxisol during the corn crops of 2011/12 and 2012. The experiment was arranged as a randomized block design with four replications, with a factorial 4 x 4 treatment arrangement as follows: 4 doses of N (0, 40, 80 and 120 kg ha-1) and 4 forms of urea (conventional urea and urea coated by three different polymers). Treatments were applied at the time of corn sowing in the first season (2010/11) and second season (2011). The residual effects of nitrogen fertilization in the corn grown in the first crop season (2011/12) and the second crop season (2012) were then assessed. The polymer -coated urea did not differ compared to the conventional urea.

title: Viability of creating a water agency in the Grande river basin, Bahia

description: ABSTRACT The work was developed from the analysis of the viability of creating a water agency in the Grande river basin, located in western Bahia, Brazil. The charging mechanisms of five different water agencies in Brazil were applied to the basin. The simulations showed the possibility of an average annual collection in the basin of over R$ 2.2 million, which would provide a median value above R$ 160,000 per year for administrative costs of the agency. Thus, considering that the median value of the annual administrative cost to state agencies is close to R$ 300,000, the collection provided by the mechanisms studied would not initially allow the creation of a water agency for the Grande river basin. However, the adoption of one of the existing water agencies would be a more appropriate alternative for the implementation during a shorter period of time, given the technical and operational structure within which the current agencies function.

title: Effect of Age on Tapering and Assortment in Araucaria angustifolia Stands

description: The objective of this research was to evaluate the effect of age on adjust taper functions and evolution of the assortment of male and female trees of Araucaria angustifolia stands. Sixty trees were sampled in a plantation located in the municipality of Laranjeiras do Sul, Paraná state, Brazil. The fifth degree polynomials were adjusted to the whole data set, and they were stratified into age classes. The evolution of the tapering and assortment of trees was analyzed with age. The results showed a slight advantage in the use of equations adjusted for age classes and a significant improvement in the stem form with increasing age. The female trees presented higher growth (0.9975 m3) than the male trees (0.9384 m3) at 30 years of age. Volumes for the noblest assortments are produced only when the stand reaches the age class of 11 to 15 years.
