title: Late Arterial Switch Surgery Under ECMO Support in a Patient with Transposition of the Great Arteries with Intact Ventricular Septum: a Case Report

description: Abstract A 30-month-old male patient with transposition of the great arteries with intact ventricular septum (TGA/IVS) is presented. Arterial switch operation (ASO) was performed in the light of echocardiographic and angiographic findings. The patient remained under extracorporeal membrane oxygenation support for seven days postoperatively, and his cardiac functions returned to normal at the postoperative 10th day. He was discharged at the postoperative 20th day. The present case, which presents one of the most advanced ages at operation for TGA/IVS among previously reported cases, is used to discuss late ASO in this study.

title: Drying process of Lentinula edodes: Influence of temperature on β-glucan content and adjustment of mathematical models

description: ABSTRACT The importance of the functional properties of edible mushrooms as a food product has been increasing and several studies have emerged to address this issue. However, the application of a conservation process is required since this is a product with a high moisture level. The aim of this study was to investigate the drying kinetics of shiitake Lentinula edodes mushrooms by means of the construction of drying curves, the mathematical modeling of the drying curves, and correlating the data obtained with the β-glucan content in order to observe the influence of temperature on its content. The drying temperatures of 35 ºC, 45 ºC and 55 ºC were applied to construct the drying curves and the β-glucan contents of the samples were quantified. Mathematical modeling was performed in order to identify the best model for the representation of the product moisture loss during the drying period. The equilibrium humidity values were 0.346% for 35 ºC, 0.892% for 45 ºC and 0.875% for 55 ºC, and the β-glucan contents showed no significant difference for the three temperatures analyzed, as confirmed by the Tukey test. Of the eight mathematical models fitted to the drying curves, the Page and the Midilli models provided the best results. Therefore, based on the findings, 55 °C appears to be the optimum temperature for the Shiitake mushroom drying process in the studied conditions, as it provides the shortest drying time and the β-glucan content is maintained.

title: Between São Paulo and Paris: the Vector calculus of the engineer Theodoro Ramos

description: Abstract In 1930, the engineer Theodoro Ramos published a book on vector calculus through the French publisher Albert Blanchard. The context of is publication, the publishing house where it was printed, the market for books of this kind in France, and the appearance of this topic in the history of calculus are discussed. Some of the contents and material aspects of several works of a similar nature published in the same period are compared with a view to bringing to light the innovations and consistencies of the book in question vis-à-vis this bibliographic corpus. Alongside its intrinsically mathematical aspects, the sometimes conflicting representations of the book by specialists and students in its trajectory between São Paulo and Europe are observed.

title: Ab initio Study of 17α-Ethinylestradiol and Estrone Molecules Interacting with Single Wall Carbon Nanotube

description: In this work, a systematic study of 17α-ethinylestradiol and estrone molecules interacting with single wall carbon nanotube is presented by means of first principle calculations. The structural properties, binding energy, charge transfer, and electronic properties were calculated and analyzed to characterize the effect of interaction of 17α-ethinylestradiol and estrone molecules on the nanotube surface. Results show that the molecular structure and electronic character of single wall carbon nanotube were not affected due to the presence of the molecules. It is observed via binding energy calculated that ethinylestradiol and estrone molecules interact weakly with the nanotube. The results are very interesting once that they suggest that nanotubes are sensitive to 17α-ethinylestradiol and estrone molecules which can lead to confection of sensor to detect these molecules.

title: Biology and External Morphology of the Immature Stages of Dirphia moderata Bouvier (Lepidoptera: Saturniidae: Hemileucinae) in Anacardium occidentale L.

description: Abstract The genus Dirphia Hübner, [1819] presents Neotropical distribution. This genus, besides causing accidents of interest in public health, is a potential defoliator pest of cultivated plants, among them the cashew tree (Anacardium occidentale L.), a crop of great economic importance. This study describes the biology, external morphology of the immature stages of Dirphia moderata Bouvier, 1929 including the first instar larva chaetotaxy. The egg stage had an average duration of 15 days, larval stage 45 days and pupa 60 days, totaling 120 days in average temperature of 28.8 °C and 59.5% relative humidity. Six instars were confirmed by the Dyar rule, with a growth rate of cephalic capsule K = 1.4 times per ínstar. The results found in the first ínstar chaetotaxy follow the general pattern known for Hemileucinae.

title: Main challenges in the identification and measurement of indirect costs in projects: a multiple case study

description: Abstract Projects have direct and indirect costs; the direct ones are easily identified and quantified, the indirect ones are difficult to control, because they are generated in favor of more than one project, and even if they are not directly related to the activities, they influence their budget. This study aims to present indirect cost identification methods, analyze the estimation models adopted for its measurement, and also analyze ways of appropriating costs in several projects. The method adopted was the analysis of multiple cases in companies of the industrial, commercial and services sectors. It was verified that projects with greater detail of the scope show less difficulty in identifying indirect costs, directly influencing the method of estimation adopted. The estimate for indirect costs is specific to each company, and its complexity is defined by the volume of data available. The appropriation of indirect costs differs between cases, but has similar objectives in its incorporation in the direct hours of the projects. It is worth highlighting the importance of project planning in the identification of indirect costs, in the choice of measurement methods, and also in the forms of costing for the budget.

title: Heritability of advertisement call properties of the Japanese quail

description: Abstract The objective of this study was to investigate genetic variances and covariances among features of the male Japanese quail advertisement call. Duration of the first, second and third syllable, the length of interval 1 (between the first and the second syllable), interval 2 (between the second and the third syllable) and damping (extension of the third syllable) were measured as temporal properties of the call. Spectral properties were peak frequencies of each syllable and the damping component. In this study, 1730 calls were recorded from 488 male Japanese quail. The restricted maximum likelihood procedure for repeated measurements was applied to estimate (co)variance components and genetic parameters for the examined traits. Heritability estimates of call parameters of the male Japanese quail ranged from low to high values (0.04-0.65) and they were generally higher for temporal properties than for spectral properties. Among the temporal properties of the call, the highest genetic correlation was between the first and the second syllable (0.96±0.251) while the lowest genetic correlation was between the first and the third syllable (0.03±0.231). Significant genetic correlations were generally high and positive among peak frequencies of the syllables. Despite the lack of apparent pattern, interval lengths tended to have positive correlation with spectral properties of the call, but the correlation of syllable lengths with spectral properties of the call was negative.

title: Relationship between phytoplankton structure and environmental variables in tropical reservoirs with different trophic states

description: ABSTRACT Phytoplankton structure is influenced by environmental factors, seasonal cycles and the trophic state of the system. The objective of the present study was to identify guilds of phytoplankton species that are representative of seasonality and trophic status. We evaluated phytoplankton biomass and species composition in five tropical reservoirs, with different trophic states and during rainy and dry periods. At most of the sampling sites, total biomass was higher during the rainy season. Moreover, high cyanobacterial biomass was observed in all reservoirs except for one of the mesotrophic reservoirs, which had no significant contribution from the group. Phytoplankton guilds associated with the trophic gradient and seasonality were identified. Additionally, trophic status was determined to be the most important community structure factor. The results emphasize the importance of taxonomic identification when monitoring phytoplankton structure and autoecology. Furthermore, these aquatic organisms are highly sensitive to environmental variations, making them useful tools for evaluating and/or monitoring the ecological condition of aquatic ecosystems.

title: Sternal Wound Complications: Results of Routine Use of Negative Pressure Wound Therapy

description: Abstract Introduction: Negative pressure wound therapy (NPWT) has significantly improved outcomes in individuals with superficial and deep sternal wound dehiscence (SWD). We report our experience with NPWT to evaluate factors influencing effectiveness, duration of treatment and postoperative hospital stay. Methods: We reviewed 92 patients with postoperative SWD following a median sternotomy. Patients were divided into 2 groups: those with a superficial SWD (Group 1; 72, 78%) and those with a deep SWD (Group 2; 20, 28%). Group 1 was further divided into 3 subgroups based on NPWT duration. Results: In both groups, none of the preoperative characteristics examined showed a significant association with longer NPWT duration. In Group 2, there was a trend for postoperative bleeding and neurological complications to be associated with longer treatment duration. In the entire series, staph infection resulted a weak predictor of NPWT duration. In each Group 1 subgroup and in Group 2, treatment days were compared with duration of hospitalization until discharge. Mean post-NPWT hospital stay was 6 days in subgroup 1, 12 days in subgroup 2 and 20 days in subgroup 3 (P&lt;0.0001). At a median 3-year follow-up, there were 4 late deaths, none related to wound complications. No cases of SWD recurrence were observed. Conclusion: Our results confirm the effectiveness of NPWT in SWD management, while excessive treatment duration might have a negative impact on the length of hospital stay. Further studies are needed to define an optimal use of NPWT protocol.

title: Thoracic Aortic Aneurysm Surgery in Marfan Patients: a Perspective from the UK

description: Abstract Objective: Cardiovascular complications in Marfan patients include progressive aortic root dilation which can precipitate acute aortic dissection, ruptured aorta, severe aortic regurgitation, or all the aforementioned. Such complications can be fatal and the cause of death prior to any surgical intervention. We set out to identify the Marfan population in England and Wales and present their surgical outcomes. Methods: A total of 306 patients with Marfan syndrome who underwent aortic root surgery were identified between April 2007 and March 2013 from NICOR database. We examined the perioperative characteristics of such cohort along with in-hospital outcomes and survival. Results: Root and ascending segment procedures on Marfan patients performed in 3.3% of the total cohort by NICOR root surgery patients. The median reported age was 40 years (IQR = 29-49 years) and 100 (32.7%) were female. Of the patients analysed, 17.3% were treated non-electively and 68.6% of them received concomitant valve procedure. The in-hospital mortality was 2.0%. Reoperation for bleeding was required in 8.2% of patients and 1.3% of them suffered a cerebrovascular accident (CVA). Mortality at 1 year was reported as 5.5%. Conclusion: The outcomes of surgery on the root and ascending aorta in Marfan patients in the United Kingdom are satisfactory; however, the overall complexities of this patient population are not well understood and would benefit from further investigations.
