Published: July 2018

Increasing the application area of powder metallurgy (PM) steels for manufacturing of high-performance structural components results in material saving, reduction in energy consumption, etc. In this study, feasibility of the manufacturing of valve bridge component for heavy duty engine utilizing lean alloyed powders and novel vacuum sintering approach, followed by low pressure carburizing, is studied. Three low alloyed steel powders were processed by conventional uniaxial pressing and sintering at 1120 and 1250°C in industrial vacuum furnace. The components were tested under high cycle fatigue testing, simulating real conditions of operation. Fatigue properties did not show significant dependence on the sintering temperature and were comparable to currently used reference cast material. Fracture surfaces of broken samples were analyzed to detect crack initiations and fracture mechanisms as well as quality of sintering. Results showed preferentially ductile failure, well developed sintering necks and clean pore surfaces, indicating good sintering. Tested material in combination with novel vacuum sintering process show to be an attractive alternative for manufacturing of this type of components for heavy duty engine applications.

The aim was to investigate the enamel health benefits of a novel toothpaste with active tetracalcium phosphate/monetite mixtures under de/remineralization cycling. The enamel de/remineralization cycling protocol was consisted of demineralization in 1% aqueous solution of citric acid at pH 3.6 with following treatment with toothpastes and soaking in remineralization storage solution. Effectiveness of toothpastes to promote remineralization was evaluated by surface microhardness measurements, enamel erosion depth, analysis of surface roughness and fluorescent optical method. The novel tetracalcium phosphate/monetite toothpaste had the same remineralization potential as commercial calcium silicate/phosphate toothpaste and significantly higher than control storage solution group (p<0.05). Surface roughness was significantly lower after addition of fluorides to dentifrice (p<0.05). The enamel erosion depth was significantly reduced by applying toothpastes as compared to negative control (p<0.05) and did not differ from calcium silicate/phosphate toothpaste (p>0.66). The results showed that dentifrice formulations containing active tetracalcium phosphate/monetite mixture with or without fluoride addition had excellent enamel remineralization potential under de/remineralization cycling and successfully promote remineralization of enamel with daily using in the form of toothpaste.

Published: July 2018

The features of molecular and electronic structures of complex compounds derived from azopyrazolone derivatives are reviewed. Despite the wide use of metal-containing azopyrazolone dyes for more than 1.5 centuries, little information on their molecular structure is found. Our recent researches allowed the introduction of new coordination modes of azopyrazolone derivatives at complexation with metals. Together with traditional bi- and tridentate coordination, the possibility of an N pyrazolone atom to be involved in coordination was also found. As a result, polymeric or polynuclear complexes were isolated and described by X-ray analysis, NMR, EPR, IR, and UV spectroscopy. The analysis of the interatomic distances in the organic anions indicated that azopyrazolone derivatives do not undergo significant azo-hydrazo tautomeric transformations at ionization and complexation despite strong shifts of the absorption bands in their IR and UV-VIS spectra.
On so-called converse reflexives in Slavic and Baltic
Authors: Holvoet Axel
Published: July 2018

The article deals with the notion of so-called converse reflexives, illustrated from Slavic and Baltic. It is argued that, though the notion of reflexive converses, i. e. pairs of converses formally differentiated by the reflexive marker, is uncontroversial, that of converse reflexives as a subtype of reflexives (middles) and a distinct gram-type in voice typology, is mistaken, as the converse effect is the result not only of the reflexive derivation but also of several other factors, viz. argument conflation and complement-modifier indeterminacy. Basically, the so-called converse reflexives are just anticausatives.
Ort der Vermittlung, Ort der Zerstörung
Authors: Szymańska Eliza
Published: July 2018

Within the last fifty years the phenomenon of the border has been scholarly described many times. In scientific works one can find many phrases like ‘crossing borders’, ‘arranging borders’, ‘perceiving borders’ or ‘experiencing borders’, which indicate dealing with the notion of borders in a metaphorical sense. Yet literary research rarely refers to the meaning of real topographical (not metaphorical) borders in literary texts. In this article the author makes an attempt to answer the question of the meaning of borders and their function in the plays ‘Night’ (Noc) and ‘Waiting for a Turk’ (Czekając na Turka) by Andrzej Stasiuk. The notion of theoretical deliberation by Sigrun Anselm is the starting point for this discussion. She presents two basic functions of the border: it can be a place of mediation (Ort der Vermittlung) or a place of destruction (Ort der Zerstörung).
Volksepos und Geheimwissen in V. Odoevskijs ErzählungSalamandra
Authors: Schulte Jörg
Published: July 2018

Vladimir Odoevsky’s storySalamandracombines the knowledge of sources from two different traditions—Finnish mythology (the Kalevala) and alchemical treatises of the seventeenth and eighteenth centuries. They meet in the motif of the Sampo that is interpreted by Odoevsky as a mythological version of the alchemical vessel. Odoevsky thus perceives the mythological text as a source for spiritual knowledge. He connects the mythological sources with the literary tradition of novels and short stories on elementaries.

Huurnink, A, Fransz, DP, de Boode, VA, Kingma, I, and van Dieën, JH. Age-matched z-scores for longitudinal monitoring of center of pressure speed in single-leg stance performance in elite male youth soccer players. J Strength Cond Res 34(2): 495–505, 2020—Coordination of corrective motor actions is considered important for soccer performance and injury prevention. A single-leg stance (SLS) test assesses the integrity and proficiency of the sensorimotor control system, quantified by center of pressure averaged speed (COPspeed). We aimed to provide age-matched z-scores for COPspeed in elite male youth soccer players. Second, we assessed a threshold for abnormal long-term change in performance, i.e., critical difference (CD). In a youth academy program, 133 soccer players of 9–18 years were tested twice for both legs (2 repetitions), and one repetition follow-up was conducted at 5.8 months (SD 2.7). Linear regression between age and COPspeed was performed to provide age-matched z-scores. Variance of differences in z-scores at baseline and between sessions was used to estimate the CD up to 5 repetitions. Intraclass correlation coefficients (ICCs) were assessed within and between sessions. The age significantly affected COPspeed (p < 0.0001), with lower values in older players (95% confidence interval; 3.45–9.17 to 2.88–5.13 cm·s−1, for 9 and 18 years, respectively). The z-score CD ranged from 1.72 (one repetition) to 1.34 (5 repetitions). The ICC of z-scores was 0.88 within session and 0.81 between sessions. In conclusion, the SLS performance in elite male youth soccer players improves with age. We determined age-matched z-scores of COPspeed, which reliably determined performance according to age. The CD allows for detection of abnormal variations in COPspeed to identify players with a (temporary) deterioration of sensorimotor function. This could be applied to concussion management, or to detect underlying physical impairments.

Gouvêa, AL, Martinez, CG, and Kurtenbach, E. Determining maximal muscle strength in mice: validity and reliability of an adapted swimming incremental overload test. J Strength Cond Res 34(8): 2360–2368, 2020—At present, there are no reliable methods to determine maximal muscle strength in small rodents. Here, we established an adapted swimming incremental overload test (SIOT) as an instrument for this purpose. First, to validate the test, BALB/c mice received 20 mg·kg−1·d−1 of dexamethasone (DEXA group) or water (control group). After 14 days, with a cumulative dose of 120 mg·kg−1 of dexamethasone, the SIOT could detect a decrease of approximately 7% in muscle strength. In addition, this decrease was consistent with a significant reduction in body (above 13.5%) and muscle (approximately 15%) weight in DEXA atrophic animals. To establish the SIOT reliability, another group of animals was evaluated for 5 consecutive days. In this second protocol, the SIOT was executed with an initial load corresponding to 12% of the mouse body weight (BW) fixed to the tail. Increments between 1 and 5% of the BW were added during each attempt to obtain the highest load that was tolerated for a time interval of 5–7 seconds. On the last day, the SIOT reliability test was performed by 2 different raters to obtain the inter-rater reproducibility. The adapted SIOT was shown to be reliable when measured by the same rater (intraclass correlation coefficient [ICC] = 0.939) and by 2 different raters (ICC = 0.830). The Bland-Altman graphical representation did not demonstrate heteroscedastic errors. Therefore, the SIOT proved to be a sensitive and reliable method to measure muscle strength, and it can be applied to small animals in different models of muscle atrophy.
Managing Populations, Diseases, and Landowner Perceptions of Prairie Dogs for Black-Footed Ferret Reintroduction
Authors: Casper A. M. Aramati , Hill Dorothy P. , Rathburn Melanie K.
Published: July 2018

The black-footed ferret (Mustela nigripes) is one of the rarest mammal species in North America. Captive breeding has prevented extinction of this species, but successful reintroduction of ferrets into their native grassland habitat is a complex endeavor. As specialist predators, ferrets depend almost exclusively on prairie dogs (Cynomys spp.) for both food and shelter, so successful black-footed ferret reintroduction hinges on maintaining large colonies of prairie dogs. However, prairie dogs are also considered agricultural pests and are often subjected to eradication programs. These eradication programs hamper efforts to reintroduce ferrets and disrupt the valuable ecosystem services prairie dogs provide in their role as both keystone and foundation species. Even when agreements are reached to maintain prairie dog colonies, plague (Yersinia pestis), which infects both prairie dogs and ferrets, can threaten the success of a ferret reintroduction program. We describe the research on the complex ecological relationships and socio-environmental challenges of reintroducing endangered black-footed ferrets, with a focus on the most abundant prairie dog species, the black-tailed prairie dog (Cynomys ludovicianus).
Laugier–Hunziker syndrome in endocrine clinical practice
Authors: Miličević Tanja , Žaja Ivan , Tešanović Deša , Radman Maja
Published: July 2018

Laugier–Hunziker syndrome (LHS) is a rare, benign and acquired disorder characterized by hyperpigmentation of the oral cavity and lips along with longitudinal melanonychia. No underlying systemic abnormalities or malignant predisposition is associated with it. In everyday clinical practice, an endocrinologist encounters certain endocrine conditions (e.g. Addison’s disease, McCune–Albright syndrome) that present with, inter alia, mucocutaneous hyperpigmentation. Even though LHS is easily distinguished from endocrine entities mentioned earlier, diagnostic evaluation usually requires skilled and thorough practitioner. Since it is the diagnosis of exclusion, a number of systemic conditions must be ruled out prior to making the final diagnosis. However, its major differential diagnosis is primarily Peutz-Jeghers syndrome, which carries an increased risk of cancer. Here, we report a case of a young woman who was referred to the endocrinologist for diagnostic evaluation of dark-colored lesions of the oral cavity and nails. All performed laboratory tests were within reference range. Endoscopic gastrointestinal evaluation did not reveal neoplastic formations. Owing to an adult-onset, asymptomatic clinical course and negative diagnostic findings, we made a final diagnosis. In this case, target diagnostic evaluation notably reduced the need for additional expensive and invasive procedures and treatments.

Learning points:

Laugier–Hunziker syndrome is a rare, acquired cause of asymptomatic, benign mucocutaneous hyperpigmentation.

Prior to making a final diagnosis, certain medical entities with overlapping clinical features must be excluded.

Endocrine conditions that usually present with the hyperpigmentation of the skin and mucous membranes (e.g. Addison’s disease, McCune–Albright syndrome) can be easily ruled out based on clinical and laboratory findings.

Its major differential diagnosis, Peutz-Jeghers syndrome is characterized by melanotic macules of the face and mouth, intestinal polyposis and significantly increased risk of different types of cancer, especially gastrointestinal.

Anamnesis, physical examination and target diagnostic evaluation reduce the need for additional invasive and expensive procedures and treatment.

Published: July 2018

Sphingolipids are involved in the regulation of cell proliferation. It has been reported that diacylglycerol and sphingosine-1-phosphate generation, during the synthesis of phospho-sphingolipids, is necessary for both, G1-S transition of cell cycle during the sustained activation of protein kinase C in various cell models (MDCK,SaccharomycesandEntamoeba) and AKT pathway activation. During the estrous cycle of the rat, AKT signaling is the main pathway involved in the regulation of uterine cell proliferation. The aim of the present study was to investigate the role of sphingolipid synthesis during proliferation of uterine cells in the estrous cycle of the rat. On metestrus day, when both luminal and glandular uterine epithelia present the maximal BrdU-labeled cells (S phase cells), there was an increase in the relative abundance of total sphingomyelins, as compared to estrus day. Myriocin, a sphingolipid synthesis inhibitor administered on estrus day, before the new cell cycle of epithelial cells is initiated, decreased the abundance of sphingomyelin, accompanied by proliferation arrest in uterine epithelial cells on metestrus day. In order to study the sphingolipid signaling pathway affected by myriocin, we evaluated the activation of the PKC-AKT-GSK3b-Cyclin D3 pathway. We observed that total and phosphorylated protein kinase C diminished in uterine epithelial cells of myriocin treated animals. Interestingly, cyclin D3 nuclear localization was blocked by myriocin, concomitantly with a decrease in nuclear pRb expression. In conclusion, we demonstrate that sphingolipid synthesis and signaling are involved in uterine epithelial cell proliferation during the estrous cycle of the rat.

Published: July 2018

Introduction: Pulsatile tinnitus (PT) is a discrete repetitive sound that is synchronous with the patient’s pulse. Incidence of abnormal, often treatable and structural findings in patients with PT has been noted to be high, ranging from 44% to 91%. So, accurate diagnosis of pathologic causes is important for treatment and prognosis.
Objective: The main objective of our study was evaluation of abnormal findings in temporal bone HRCT scan and CTA/CTV in patients affected by pulsatile tinnitus, and comparing these findings with unaffected ear of the same individuals.
Methods: A case-control study was conducted and all the patients who had subjective pulsatile tinnitus with normal physical examinations among outpatient individuals referred to our institution; Rasoul Akram Hospital from September 2015 to august 2017 was included in this study. All patients underwent brain CT Angiography/Venography (CTA/V) and temporal bone high resolution CT scan (HRCT), and their findings were compared.
Results: Thirty patients consist of 20 females and 10 males with mean age of 50.83 years were evaluated in this study. Pulsatile tinnitus was unilateral in all patients except one. Comparing results of CTA/V and temporal HRCT scan in the affected ear showed that temporal HRCT scan in 19(63.3%) out of 30 patients reported normal, while CTA/V only in eight (26.6%) of these patients reported normally. So, capability of CTA/V is statistically significant in diagnosis of abnormalities in the affected ear (P=0.012).
Conclusion: Our findings demonstrate that CTA/V can be a more accurate imaging tool than temporal bone HRCT in initial assessment of patients with subjective pulsatile tinnitus and normal physical examination, and should be done as the first imaging tool in these patients.

Purpose. This study investigates the possibility of improving the quality of grinding steel balls with a diameter of 100 mm by using Q-n-P heat treatment. Methodology. Steel grinding balls with a diameter of 100 mm, obtained by transverse screw rolling, were used as a material. The heat treatment consisted of balls quenching in a drum-type device according to various modes and subsequent tempering. The quenching modes provided the bulk temperature of the balls in the range of 120-240 оС, which is lower than the martensitic point Ms of the steel. After quenching, the balls were immediately tempered at 170-300 °C for 2-10 hours. The treated balls were visually examined, tested for hardness and impact resistance. The hardness was measured according to the Rockwell method by scale "C", the microhardness was measured with microhardness tester "Affri" at a load of 50 g. The impact resistance of the balls was evaluated by impact of a dropped load with impact energy of 6.8 kJ. Microstructural analysis was conducted using an optical microscope "Axiovert 40-M". The amount of residual austenite was determined using an "IV-Pro Rigaku" diffractometer in copper Ka-radiation. Findings. It is shown that, as a result of treatment of 100 mm diameter balls of chromium-manganese steel according the standard mode, the cracks occur on balls surface. Using Q-n-P heat treatment allows achieving higher hardness through the cross section (within 54-57 HRC) while quenching cracks are absent on the balls. The Q-n-P-treated balls have high impact resistance under repeated impacts with energy of 6.8 kJ. Originality. For the first time the authors investigated the feasibility of using the Q-n-P heat treatment for steel grinding balls of large diameter made of steel with increased hardenability. It has been determined that Q-n-P-processing allows to significantly increase (by 10 HRC) the bulk hardness of 100 mm diameter balls, while retaining their high impact resistance in tests with a dropped load. The obtaining of such properties is pro-vided by the relaxation of quenching stresses and the formation of a two-phase martensitic-austenite structure with an increased amount (25-30 %) of retained austenite. The latter becomes possible due to the process of partitioning carbon from martensite to austenite with enrichment of the latter to 1.12 % C. Practical value. The advisability of Q-n-P-heat treatment in the production of steel grinding balls with higher bulk hardness is shown.

Published: July 2018

Purpose. The main purpose of this paper is to analyze the existing methods for surveying curves in a plan, to study the influence of the errors in measuring plan parameters on the permitted speeds of motion, to develop re-commendations for reducing road disturbances by bringing the parameters of curves to the standards that operate in Ukraine in the directions of accelerated and high-speed train traffic. The problem of restructuring the curves was not so acute until there was a need to increase the speed of motion and technical condition monitoring of the track plan. Unreliable determination of the curves parameters leads to unjustified restrictions in the speed of motion or to large volumes of straightening operations. Methodology. The methodology used in the paper provides for a comprehensive and detailed study of different ways of railway curves survey, aimed at developing and obtaining the optimal solutions for the railway track plan. To date, there are different methods of survey the actual geometry of the railway track. To carry out research in various sections of complexity and for a long time of the railway track operation, the most convenient, first of all, considering the regularity of arrivals, there is a tape of the track-measuring car. However, this method is used to assess the state of the railway track, and not to determine the exact geometric position. Thus, when trying to determine the actual outline of the track unevenness using a track-measuring tape, a number of difficulties arise. When forming a mathematical model of the existing plan, the assumption is used: it is considered that three adjacent points on the curve are located along the circumference. The work of track renewal trains is based on this principle. As a result of track renewal operations with the aim of reducing the volume of flattening, the curve does not correspond to the initial passport data. Findings. The results of the work come out of the analysis of different approaches and methods of surveying the plan of the line, the parameters influence of the curves on establishing the permissible speed of motion. The recommendations received in the work will help to increase the efficiency of design decisions and the quality of railway track reconstruction as a whole. Originality. Scientific approaches to assessing the state of curves, studying the influence of their parameters on the permissible speed of trains, have been further developed. The system of criteria for assessing the state of curves that affect the accumulation of track disturbances in the plan is supplemented. Practical value. The results obtained will be useful for carrying out measures to improve speed, improve the smoothness of train traffic and the level of travel comfort on curved track sections, especially in the areas of accelerated and high-speed train traffic.

Purpose. The work aims at structural-functional description of the existing construction of hatch covers of gondola cars to find possible ways of their modernization and improvement. Methodology. The research and analysis are based on principles of morphological study of technical systems and systems approach. The research takes into account the results of the leading research on the topic, the authors' own development, mathematical justification and computer modeling. Calculation of the structural elements of the rolling stock was carried using modern normative and developed methodologies. Findings. The system approach in creating an innovative hatch cover allowed the design to be presented in the form of a series of interconnected and interacting subsystems, taking into account the main factors of their functioning. Authors developed the structural-functional model of the hatch cover of the gondola car, which showed that the hatch cover plate is the basic element, the structural-parametric and functional properties of which determine the corresponding characteristics of other nodal and base elements of its design. We established that the main functions of the hatch cover are distributed through the constituent elements of the first hierarchical level (between nodes): the frame serves as the reinforcing element of the plate and the base for installing other nodes, except the torsion ones. The proposed theoretical propositions, methodological foundations and practical methods of structural and functional analysis are expedient for using in the search for optimization ways and other elements of rolling stock, as well as objects of transport engineering. Originality. The methodological foundations for the creation of a structural and functional description of the hatch cover are proposed and the results of its implementation are presented, which can be used in studies of the processes of their functioning, perception and redistribution of different types of loads, taxonomy, increasing the degree of their ideality, identification of objects considered in design, repair. Practical value. The structural-functional description allowed projecting an innovative design of the hatch cover, including its frameless execution, a model with a convex design of the plate in the direction of counteracting the mass of the cargo. Using the proposed models of hatch covers, effective modernization of the domestic park of gondola cars is possible.

ABSTRACT Professor Charcot had several pupils in his famous neurological service at the Salpêtrière Hospital in Paris, France. Among them, Édouard Brissaud was one of Charcot’s favorite pupils, temporarily becoming his successor after Charcot’s death. Brissaud’s neurological contributions were significant, including the description of hemifacial spasm, “geste antagoniste” in dystonia, pseudobulbar affect, post-traumatic stress disorder, the Brissaud-Sicard syndrome, and Brissaud’s sign. Additionally, Brissaud was the first to suggest that Parkinson’s disease pathology could be related to the substantia nigra.

Published: July 2018

ABSTRACT The rice husk ash has been applied in agricultural land, with potential of replace limestone and, supply phosphorus and potassium. However, its residual effect in soil is still unknown. This investigation aimed to evaluate the reaction rate and residual effect of rice husk ash in soils acidity parameters. A field experiment was conducted with five treatments: four rice husk ash dosages 0, 30, 60 and 120 t ha-1 and one treatment with recommended soil lime and fertilizer (dolomitic limestone to reach pH 6, 150 kg ha-1 P2O5 as single superphosphate and 80 kg ha-1 K2O as potassium chloride) where five soil samples. Soil samples were collected in the layers 0.00 - 0.10 m and 0.10 - 0.20 m at 15, 211, 400, 517 and 804 days after ash incorporation. Chemical attributes were determined: soil pH (pH), soil base, exchangeable cation values (Ca, Mg, K and Na) and cation exchange capacity (CEC) at pH 7. Results showed that reaction rate of rice husk ash is faster when compared to liming. As greater was rice husk ash dosage applied in soil, higher is the residual effect in pH. As corrective of soil acidity, the residual effect of rice husk ash is just the required time to occur the natural process of reacidification and leaching of basic cations, about 33 months for soils and weather conditions similar to this work.
The founding narratives of the myth of economic development and the Brazilian neo-developmentalism
Authors: Cristaldo Rômulo Carvalho , Senna Juliana Rodrigues de , Matos Lara Sousa
Published: July 2018

Abstract This article aims to interpret the most well-known theories of economic development based on the assumption that these theories are contemporary mythological tales and, consequently, the Brazilian 2000’s neo-developmentalism agenda as an inexact unique blend of them all. The study uses Roland Barthes’ semiotic interpretation on the social structure and roles of myths to argue that theories of development are rather a compound of ideologies than a scientific field of inquiry. In addition, the article draws a parallel between Joseph Campbell’s hero’s journey and the five widely known narratives of development: Protectionist, Keynesian, Institutional, Entrepreneurial and Neoclassical.

Published: July 2018

Abstract This study aimed to propose a safe methodology for the control anthracnose caused by the fungus Colletotrichum gloeosporioides in the papaya ( Carica papayaL.). In addition, yeast present in epiphytic microbiota associated with this fruit were isolated and selected as biocontrol agents, its use in classical and integrated biological control protocols with GRAS substances. For selection as biocontrol agents, the obtained isolates were tested for their ability to: produce antagonistic substances against C. gloeosporioides, not grow at 37ºC and subsequently tested for their potential control. Considering the total of 85 isolated yeasts, only UFT 5852 was selected in the above mentioned tests and due to this it was used in biological control tests in vivo. It was identified molecularly belonging to species Anthracocystis grodzinskae by the sequencing the D1/D2 domain. The results of the biocontrol had showed that the yeast presented a reduction of the disease severity by 93.7%, the sodium bicarbonate 100%, and the biological control integrated with sodium bicarbonate showed a decrease of 84.4%. The treatments did not differ 5% by Tukey test. However, the sodium bicarbonate at 1% showed the best strategy for the control of Anthracnose produced by the phytopathogenic fungus C. gloeosporioides in papaya due accessible strategy.

Abstract The lack of programs to improve the strawberry crop in Brazil has led to a growing increase in the use of seedlings imported from Chile, which leads to a certain dependence of imported material on the part of the producers and increases the production even more, since the producers have. This proves even more the need for the development of cultivars adapted to the local conditions of cultivation. In this sense, the aim was to evaluate the post-harvest of fruits of 15 hybrids of strawberry obtained from the cross between commercial cultivars, in order to select the materials with chemical quality superior to the cultivars most planted in Brazil. The contents of soluble solids, titratable acidity, ratio, vitamin C, anthocyanins and phenol were evaluated. The characterization of strawberry hybrids indicated that the RVFS 13-07, RVFS 13-24, RVCS 13-07, RVCS 13-10 and RVCA 13-08 materials stood out in post-harvest evaluations, with higher levels of functional compounds (vitamin C, anthocyanins and phenolics) and higher values of quality parameters (soluble solids, titratable acidity and ratio), important characteristics for the in natura consumption or for use by the industry. These hybrids were shown to be promising to continue the crop breeding program by demonstrating that they carried characteristics of interest for intraspecific crosses. The values obtained for the analyzed characteristics were higher than the values found in the literature for the cultivars most planted and consumed in Brazil and in the World, which demonstrates the efficiency in the selection process.

Abstract The acerola tree (Malpighia emarginata Sessé &Moc. ex DC.) is a fruit species that has prospered in the Brazilian tropical regions, especially in the Northeast, thanks to the high content of vitamin C in the fruits, among other characteristics that make it attractive to the producer, such as early production. Although there is increasing demand for the product, the production of certified seedlings of good commercial varieties is still a barrier to further expansion of the crop. This review aims to present, in a comprehensive way, technical information on how the spread has been made since its introduction in the country, as well as innovations and advances. Traditionally, propagation is carried out through seeds, cuttings and by grafting on top of common acerola rootstocks, with no defined origin. The advances presented are focused on the use of new canopy and rootstock varieties, including the use of double grafting, minicutting and tissue culture, with studies still in progress, and use of new substrates such as coconut fiber.

Abstract Objective: The aim of this study was to identify radiological and clinical risk factors for death in newborns with necrotizing enterocolitis. Materials and Methods: This was a retrospective cohort study, based on radiological examinations and medical charts of 66 infants with necrotizing enterocolitis, as confirmed by a finding of intestinal pneumatosis (stage IIA, according to modified Bell’s staging criteria). Radiological and clinical variables were evaluated. Results: Of the 66 infants evaluated, 14 (21.2%) presented pneumatosis in the large and small bowel; 7 (10.6%) presented air in the portal system; and 12 (18.2%) died. Bivariate analysis revealed that the following variables were associated with death: bowel perforation; pneumatosis in the large and small bowel; air in the portal system; earlier gestational age; longer time on mechanical ventilation before the identification of pneumatosis; and longer time on mechanical ventilation before discharge or death. In the multivariate regression, the following variables remained as predictors of death: pneumatosis in the large and small intestines (odds ratio [OR] = 12.4; 95% confidence interval [95% CI] = 1.2-127.4; p = 0.035), perforation (OR = 23.2; 95% CI = 2.2-246.7; p = 0.009), and air in the portal system (OR = 69.7; 95% CI = 4.3-[not calculated]; p = 0.003). Conclusion: The set of factors most strongly associated with death in infants with necrotizing enterocolitis comprised extensive pneumatosis, pneumoperitoneum, and air in the portal system. Our findings confirm the importance of radiological imaging in the diagnosis and monitoring of necrotizing enterocolitis.

RESUMO Objetivo: mensurar a eficácia da perda de peso, analisar a evolução de comorbidades, investigar a qualidade de vida e avaliar o protocolo BAROS (Bariatric Analysis and Reporting Outcome System) no pós-operatório de pacientes submetidos à cirurgia bariátrica. Métodos: estudo transversal e quantitativo, com força de verdade de 95% (P=0,05), de 103 pacientes submetidos à Gastrectomia Vertical SLEEVE (40) e à Derivação Gástrica em Y de Roux (63), a partir de quatro meses de pós-operatório. A pesquisa foi realizada no Ambulatório de Cirurgia Geral do Hospital das Clínicas da Universidade Federal de Pernambuco, tendo sido utilizado o protocolo BAROS. Resultados: a maioria dos pacientes era do sexo feminino (89,3%). A média de idade foi de 44,23 anos. A média de perda percentual do excesso de peso foi de 69,35%. A média de tempo de seguimento pós-cirúrgico foi de 41,87 meses (±37,35). As comorbidades com maior percentagem de resolução foram: apneia do sono (90,2%), diabetes (80,7%) e hipertensão (70,8%). As complicações mais frequentes foram queda de cabelo (79,6%), deficiência nutricional (37,9%) e anemia (35%). O protocolo BAROS demonstrou que a qualidade de vida foi avaliada de forma positiva em 93,2% dos casos. O questionário Moorehead-Ardelt demonstrou que a qualidade de vida "melhorou" ou "melhorou muito" para 94,1% dos pacientes. Conclusão: a cirurgia bariátrica demonstrou ser um procedimento eficaz no tratamento da obesidade mórbida e no controle das comorbidades. A análise da qualidade de vida foi avaliada de forma positiva através do protocolo BAROS.
O não-ser em Parmênides de Eleia
Authors: Galgano Nicola Stefano
Published: July 2018

Resumo: No fragmento DK 28 B 2 de seu poema, Parmênides apresenta seu método para distinguir a persuasão verdadeira da falta de persuasão verdadeira. As famosas duas vias para o pensar que ele propõe são o enunciado complexo de um sistema que quer garantir a veracidade das afirmações para obter, afinal, um discurso confiável, o único capaz de persuasão verdadeira. O presente artigo mostra que o papel central da argumentação parmenidiana é atribuído ao não-ser, uma noção derivada certamente de uma reflexão sobre a impossibilidade da negação do ser. Assim, o inteiro fragmento é interpretado a partir dessa noção central, evidenciando que Parmênides descobre aquela impossibilidade de negação, que hoje nós chamamos de "contradição", e enuncia qual é a maneira de evitar a contradição no pensamento e no discurso, uma regra que atualmente nós chamamos princípio de não-contradição. O estudo aqui apresentado faz uma investigação detalhada da noção de não-ser, no fragmento DK 28 B 2, oferecendo finalmente uma nova tradução.
La soberanía más allá de la instancia del poder y del dominio en torno a la bio-política de Jacques Derrida
Authors: Trujillo Iván
Published: July 2018

Resumen: En el presente artículo planteamos la existencia, en el Derrida de La diseminación, de cierto pensamiento sobre la bio-política. Incluyendo la figura animal, este pensamiento es también el pensamiento de una soberanía más allá de la instancia del poder y del dominio. El Seminario La bestia y el soberano publicado postumamente, parece ser su más acabada expresión. En primer lugar, seguimos las indicaciones realizadas por Derrida acerca de la pintura como zôgraphia en La diseminación (1972). La deconstrucción derridiana de lo que llamamos "la secuencia soberana", nos permite analizar la relación entre el problema de "la animalidad de la escritura" y de la soberanía como corolario del pensamiento de una cierta bio-política o zoo-política tempranamente discernida. En segundo lugar, exploramos en algunos de los pliegues de la discusión de Derrida con Agamben y con Foucault sobre el concepto de vida, los términos de una cierta politicidad de la vida que incluye la animalidad y susceptible de ser situada más allá de la instancia del poder y del dominio. Finalmente, y en tercer lugar, tras confrontar los conceptos de soberanía de Foucault y de Derrida a propósito del Leviatán de Hobbes, retomamos el problema inicial de la zôgraphia en relación con la cual buscamos aproximarnos a lo que Derrida va a llamar en el Seminario La bestia y el soberano "la doble y contradictoria figuración".
Hannah Arendt e o problema da secularização na fundação de novos corpos políticos
Authors: Eccel Daiane
Published: July 2018

Resumo: A questão da secularização também tem espaço no pensamento de Hannah Arendt. A autora sempre procurou um conceito puro de política (reinen Begriff des Politischen), que fosse independente de qualquer raiz religiosa ou que estivesse desvinculado de toda fonte metafísica e transcendente. No entanto, desde Platão, a tradição do pensamento político ocidental não encontra tal autonomia e esse problema se repete nos tempos modernos, sobretudo no momento da fundação de corpos políticos, como é o caso das revoluções, por exemplo. Além disso, Arendt também esclarece como o vácuo de autoridade contribui para a permanência do problema e reforça a necessidade daquilo que ela entende como "o incômodo problema do absoluto". Este artigo privilegia a investigação de tais questões através dos textos Sobre a revolução, Religião e política e O que é autoridade? e sustenta a necessidade da separação das esferas política e religiosa, visando à boa manutenção de ambas.
Interconexões Setoriais e PIB per capita: há relação direta entre ambas as variáveis?
Authors: Silva Gabriel Dias da , Perobelli Fernando Salgueiro
Published: July 2018

Resumo Desde que autores como Perroux (1955) e Hirschman (1958) propuseram a fomentação de ligações intersetoriais como estratégia para o crescimento econômico, alguns países de menor renda buscaram o desenvolvimento industrial, enquanto que nos mais ricos observaram-se processos de desindustrialização e crescimento de importância dos serviços. Seguindo essa contextualização, este trabalho avalia as relações que o total de interconexões dentro de uma economia poderiam ter com o PIB per capita e sua taxa de crescimento. Assim, a partir de dados de insumo produto de 40 países para os anos entre de 1995 e 2011, foram construídas medidas agregadas de ligações (MAL) totais, dos setores primários, industriais e de serviços, avaliadas com o auxílio da técnica de análise de agrupamentos. Os resultados revelam tendências de redução nas conexões dos setores industriais, sua associação positiva com o crescimento do PIB percapita, e crescimento da integração dos serviços com as demais atividades.
