title: Patrimonial imaginaries in urban reconversion processes. Puerto Norte, Rosario, Argentina

description: Abstract Progressive commercialization spaces and urban symbols are among the phenomena that characterize cities in the context of neoliberalism. The patrimony has a prominent role as a discursive tool and resource used in the urban reconversion processes, reducing conflicts and disputes. Although patrimonial is symbolically linked to urban identity, we maintain that different actors rise matrices of different transversal meanings, shared and even contradictory, forming complex patrimonial imaginaries. This work aims to investigate the patrimonial imaginary in the urban spaces under requalification process, as the case of Puerto Norte in the Refinería neighborhood of Rosario. Thus, we address discourses and representations produced by different actors - local government, real estate entrepreneurs and neighborhood associations - and analyze differences, agreements and tensions between different meanings in circulation, based on a theoretical methodological matrix focused on urban imaginaries.

title: GROWTH AND NUTRITIONAL EFFICIENCY OF NITROGEN IN CULTIVARS OF FORAGE MILLET IN THE AMAZON

description: ABSTRACT: The millet is a forage with high yield potential, mainly due to its high tolerance to water deficit and adaptation to soils of low fertility. Even being adapted to soils of low fertility, it is responsive to nitrogen fertilization. The objective was to evaluate the growth and nutritional efficiency of millet forage cultivars, due to nitrogen (N). The experiment was carried out in a greenhouse, in a typical Yellow Oxisol Dystrophic. The experimental design was a completely randomized design, arranged in a 4 x 2 factorial scheme with six repetitions. The factors were the control treatment (without fertilization with N) and three doses of N (75, 150 and 225 kg ha-1) in the form of urea and ammonium sulfate and two cultivars of pearl millet (BN2 and ADR500). The harvest was performed 80 days after the emergency. The higher production of dry matter of aerial part was obtained with the estimated dose of 179 kg ha-1 of N. The cultivar ADR500 showed the highest height and greater efficiency of translocation, while the BN2 showed higher N content of the aerial part and roots. The greater efficiency of use and translocation of N were achieved with doses estimated for 109 and 133 ha-1 of N for the cultivars ADR500 and BN2, respectively.

title: Lipid disorders among Black Africans non-users of lipid-lowering medication

description: ABSTRACT Objective: Angola is a sub-Saharan African country where the population has scarce access to lipidlowering medication. We sought to determine the frequency of lipid disorders among Angolan nonusers of lipid-lowering medication. Material and methods: A cross-sectional descriptive study was carried out in a sample of 604 workers from the public sector. Blood pressure and anthropometric data were measured along with biochemical parameters including total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). LDL-C to HDL-C ratio (LDL-C/HDL-C) was obtained from LDL-C and HDL-C levels. Results: High frequencies of elevated blood pressure (44.8%), metabolic syndrome (20.2%), increased TC (39.2%) and increased LDL-C (19.3%) were found. Low HDL-C was more frequent in women (62.4% vs. 36.1%, p &lt; 0.001). Isolated hypercholesterolemia was more frequent in men (9.6% vs. 2.5%, p &lt; 0.001). Among men TC, TG, LDL-C and LDL-C/HDL-C ratio were higher and HDL-C was lower in obese than in low-weight and normal-weight participants. Among women TC, TG, LDL-C and LDL-C/HDL-C ratio were higher in obese than in normal-weight participants. Significant linear trend of increasing TC and LDL-C levels as age increased was detected for both genders (p for trend &lt; 0.05). Conclusion: The results of our study showed a high frequency of lipid disorders in Angolan non-users of lipid-lowering medication.

title: Electrical conductivity test in Piptadenia moniliformis Benth. seeds

description: The electrical conductivity test is a quick, practical and objective test force; however, its effectiveness varies according to the species, quantity of seed, water volumes, soaking temperature, among other factors. The objective of this study was to evaluate the physiological quality of P.moniliformis seeds lots by means of the electrical conductivity test, testing different methodologies. For this, two lots were tested in three quantities of time (25, 50 and 75 seeds) and nine soaking times (2, 4, 6 , 12, 24 , 36, 48, 60 and 72 hours) in three volumes of water (50, 75 and 100 mL) at 25 °C. To evaluate the initial quality of the lots, germination percentage, germination speed index, average time of germination, length and dry mass of seedlings were determined. The use of the electrical conductivity test of P. moniliformis seeds is recommended using 75 seeds in 75 mL of water for 2 hours at 25 °C or seeds in 50 mL distilled water with 50 seeds per 6 hours at 25 °C.

title: Odontoma associated with impacted mandibular canine: surgically guided eruption

description: ABSTRACT Odontoma is the most common type of odontogenic tumor and is most often diagnosed in the second decade of life. This benign tumor has a slow growth and is asymptomatic, which favors its persistence in the bone until some clinical sign emerges or the tumor or be detected in a routine radiograph. The aim of this case report was to present a clinic case of a 13-year-old male, who presented delayed exfoliation of the mandibular right primary canine. The radiographic exam revealed a radiopaque image in the anterior region of the mandible produced by structures that resembled the formation of teeth surrounded by a radiolucent area. Adjacent to the tumor, the impacted mandibular right canine was identified with deviation of its eruption axis. The clinical diagnosis was compound odontoma. Treatment consisted of the removal of the tumor and the surgically-assisted eruption of the tooth without orthodontic traction. After three years of follow up, the patient has exhibited positive results. It is possible to surgically assist the eruption of an impacted tooth, with a deviated axis, associated with an odontoma through the removal of the tumor and of the physical barrier (ostectomy) without orthodontic traction.

title: Updating the debate on the Jewish populations in North Africa

description: ABSTRACT This paper analyses the debate on North African Jews and seeks to articulate the discussions and critiques with the model of cultural assimilation and ancient Roman historiographical understanding, reproduced by classical and post-classical humanist thought. It claims that focus on regional context reveals ambiguities and uncertainties inherent to the processes of domination and enables a variety of associations for cultural identities formation. After the Phoenician and Roman colonization periods, hypogea and catacombs became equally conventional methods for burial of the dead in specific areas of North Africa. Knowledge on funerary practices and ideas of death rituals allow us to address cultural dynamics in the Roman world and to interpret artefacts within a structure through which individuals relate to each other, acquire their understandings, establish their associations and their differences as well. Roman religion was based in correct practice and execution of rites, orthopraxy, and North African Jews have marked their own tombs in a way that would simultaneously index resemblances with neighbour social groups as well as onomastic or symbolic differences.

title: Development and Optimization of a Catalytic Thruster for Hydrogen Peroxide Decomposition

description: ABSTRACT: Hydrogen peroxide is a non toxic, low cost, green monopropellant with a significant potential for applications in satellite microthrusters. It presents a density-specific impulse similar to hydrazine. A new bulk mixed oxide catalyst for decomposition of hydrogen peroxide has been developed and tested in a 2 N thruster with modular parts, allowing the use of catalytic beds with different diameters and lengths. A method of experiment design with a star configuration was implemented to optimize the catalytic bed geometry, in order to yield complete peroxide decomposition, reduce thruster size and volume and provide maximum thrust.

title: ADAPTABILITY AND PHENOTYPIC STABILITY OF LETTUCE CULTIVARS IN A SEMIARID REGION

description: ABSTRACT Studies on lettuce genotypes growing in different environments and planting seasons are important for this crop because its productive potential is greatly affected by environmental conditions. The mixed model methodology (REML/BLUP) have been used to evaluate the effects of the genotype-environment interaction on crops. Thus, the objective of the present work was to estimate parameters of adaptability and the phenotypic stability in lettuce cultivars grown in a semiarid region of Brazil, using a mixed model. Twelve lettuce cultivars from the Americana (Angelina, Amélia, and Tainá), Crespa (Scarlet, Vera, Isabela, and Vanda), Mimosa (Mila, Mimosa, and Lavínia), and Lisa (Elisa and Regiane) groups were evaluated. The experiments were conducted in a randomized complete block design, with four replications. The genetic parameters were estimated by the REML/BLUP method; and the simultaneous selection of productivity, stability, and adaptability of the genotypes was based on harmonic means of relative performances of predicted genotypic values (HMRPPGV). The Amélia, Angelina, and Tainá cultivars stood out for yield. The Regiane and Elisa cultivars presented significant responses in yield and number of leaves and are the most suitable for growing in the environmental conditions of Mossoró, RN, Brazil. The Crespa and Mimosa groups presented no stability and adaptability to the environmental conditions in which the experiments were conducted. More genotypes of all lettuce groups should be evaluated, and breeding programs should be developed to obtain genotypes with higher productivity, quality, and resistance to heat for semiarid regions.

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: 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: 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.
