Auf dem Weg in die Moderne: Adolf Heyduks Idylle Oldřich a Božena
Authors: Ibler Reinhard
Published: March 2020

The love story of the Přemyslid duke Oldřich (1012–1033, 1034) and the peasant girl Božena Křesinová, who became his second wife, was a popular subject in the Bohemian chronicles of the Middle Ages and the Early Modern Age. The story’s social and national connotations (Božena being a lower class Czech girl) may have been one of the main factors of its renewed popularity in Czech literature and art since the end of the 18th century. Especially the Czech National Revival gave birth to several works dealing with this topic, such as ballads, romances, dramas, operas and paintings. An absolutely different way of treating the subject was presented by Adolf Heyduk (1835–1923), a representative of the ‘May School’ (Májovci). In his idyll Oldřich a Božena (1879), Heyduk largely ignored the story’s national and social implications and focussed on the love theme. Thus he was also in line with the Májovci poetics being directed against the revivalists’ strictly nationalist and patriotic orientation in literature and culture. Heyduk, moreover, strengthened the work’s symbolic and psychological dimensions, especially in an abundance of nature scenes and in Božena’s songs giving an insight into the girl’s hopes, dreams and latent desires. The work thus gains a new aesthetic quality bringing Oldřich a Božena close to modernistic conceptions.
Andrej Platonovs ‚Unsterblichkeit‘
Authors: Meier Nils
Published: March 2020

It has often been claimed that the journalist Platonov reproduced the idea of ‘immortality’ which belonged to the soviet topos of ‘new man’ and that the poet Platonov contradicted the journalist by making this idea ridiculous. Such an overly complicated understanding of Platonov’s work can be replaced by a simpler explanation: An analysis of several of his texts shows that the young and the elder Platonov, the poet and the journalist were unanimously in favour of a certain concept of ‘immortality’, that simply did not fit into the then-mainstream topos of ‘new man’. This first part of the study explains how Platonov rejected the fantastic notion of ‘immortality’ that dominated the corresponding discussions in soviet intellectual life in the decade after 1917. The second part analyses Platonov’s relationship to the stalinist version of ‘new man’ and its specific variant of ‘immortality’.
Spirituality, medicine, and tradition. Some thoughts aboutHostility and Hospitality
Authors: Jobin Guy
Published: March 2020

This book by authors Michael J. and Tracy A. Balboni offers a critique of the direction taken by medicine in the modern age. It is critical in the sense that, first, it identifies the shortcomings of current medical, or more generally, caregiving practice and, second, it proposes various ways (training, institutional organization, research, etc.) to correct the serious deficiencies identified. I subscribe willingly to the same critical tradition as the authors. Although I will diverge from their proposals on certain points, I agree with them that the spiritual discourse generated in Western healthcare establishments deserves critical attention, backed up by the resources of theological reflection alongside the contributions made in other fields of knowledge. I also believe that a theological critique can be constructive and help illuminate the spiritual experience during illness, leading to a fairer appraisal, by clinicians, of this facet of the experience of illness. My critical appraisal will cover the following topics: the theological assumptions underlying the Balbonis’ account of the development of medicine in the modern era, the idea of a spiritual therapy, and, finally, the spiritual anthropology that supports the structural pluralism model and its institutionalization.
Microwave-Assisted Synthesis of Cobalt Oxide/Reduced Graphene Oxide (Co3O4–rGo) Composite and its Sulfite Enhanced Photocatalytic Degradation of Organic Dyes

Published: March 2020

One-pot synthesis of Co3O4 nanocrystals on reduced graphene oxide (rGO) was carried out by reacting cobalt nitrate, L-arginine, extract of Laportae aestuans as oxidant, fuel and reducing agent, respectively, in a domestic microwave. Morphologies of Co3O4–rGo (RGCO) composite was elucidated using UV-Vis, FT-IR, TEM, SEM, EDX, XRD and photoluminescence spectroscopies. The synthesized RGCO composite was applied as heterogeneous photocatalyst in the activation of Na2SO3 (sulfite) as sacrificial agent to degrade cationic dyes: rhodamine B (RhB) and methylene blue (MB), under visible light, at neutral pH 7.0. Photocatalytic performance of as-prepared RGCO was significantly enhanced in the presence of Na2SO3. Enhanced photocatalytic activity of RGCO was attributed to the synergistic effects between sulfite radicals generated in situ, and reduced graphene oxide, in which rGO served as electron sink to suppress recombination of photogenerated charge carriers. Plausible mechanistic pathways responsible for the activation of sulfite anions in situ are presented in this paper.
„Doing Gender“ lernen. Geschlechtergerechte Bildung im Religionsunterricht
Authors: Kohler-Spiegel Helga
Published: March 2020

„Doing gender“ nimmt die soziale Konstruktion von Geschlecht in den Blick. Geschlecht bzw. Geschlechtszugehörigkeit werden nicht als Eigenschaft oder Merkmal von Individuen verstanden, sondern sie sind sozial und kulturell konstruiert und in Interaktionen ständig inszeniert, produziert und reproduziert. Doing gender im Schulbereich betrifft das Grundverständnis und die Haltung der Lehrpersonen zum Thema Geschlecht sowie die Institution Schule insgesamt. Dieses Grundverständnis ist auch im Religionsunterricht umzusetzen, um geschlechtergerechte Bildung im religiösen Bereich zu gewährleisten. Beispiele dazu runden den Beitrag.

This study evaluated the wear (under dry conditions) and scratch resistance of a cobalt boride layer exposed to a diffusion annealing process (DAP). Firstly, the powder-pack boriding process (PPBP) was conducted at 1,223 K with 4 h of exposure to develop a CoB-Co2B layer on the surface of the ASTM F1537 alloy, followed by a DAP at 1,273 K with 2 h of exposure in an argon atmosphere. Before the wear and scratch tests, the resulting cobalt boride layers, obtained by the PPBP and PPBP + DAP, were characterized by X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, and depth-sensing Vickers microindentation techniques. The wear sliding tests, on the PPBP and PPBP + DAP, were performed using a ball-on-flat configuration comprising an alumina ball as a counterpart using a constant normal force and different relative wear distances (50, 100, and 150 m). In addition, the scratch tests were carried out over the surface of the PPBP and PPBP + DAP using a Rockwell-C diamond indenter with a continuously increasing normal force from 5 to 150 N. Finally, and according to the entire set of experimental conditions, the results showed that the presence of the CoB-Co2B layer obtained by the PPBP on the surface of the ASTM F1537 alloy increased the wear resistance compared with the values estimated on the PPBP + DAP. In contrast, the effect of the DAP on the cobalt boride layer enhanced the practical adhesion resistance of the layer-substrate system based on the critical loads obtained during the scratch tests.

Published: March 2020

This paper presents practice and application of Design of Experiment techniques and Genetic Algorithm in single and multi-objective optimization with low cost, robustness, and high effectiveness through 3D printing case studies. 3D printing brings many benefits for engineering design, product development, and production process. However, it faces many challenges related to parameters control. The wrong parameter setup can result in excessive time, high production cost, waste material, and low-quality printing. This study is conducted to optimize the parameter sets for 3D Fused Deposition Modelling (FDM) products. The parameter sets, i.e., layer height, infill percentage, printing temperature, printing speed with different levels are experimented and analyzed to build mathematic models. The objectives are to describe the relationship between the inputs (parameter values) and the outputs (printing quality in term of weight, printing time and tensile strength of products). Single-objective and multi-objective models according to user’s desire are constructed and studied to identify the optimal set, optimal trade-off set of parameters. Besides, an integrated method of response surface methodology and Genetic algorithm to deal with multi-objective optimization is discussed in the paper. 3D printer, testing machines, and quality tools are used for doing experiments, measurement and collecting data. Minitab and Matlab software aid for analysis and decision-making. Proposed solutions for handling multi-objective optimization through 3D Fused Deposition Modelling product printing case study are practical and can extend for other case studies.

Published: March 2020

Multiwall Carbon nanotubes (MWCNTs) are frequently attractive due to their novel physical and chemical characteristics, as well as their larger aspect ratio and higher conductivity. Therefore, MWCNTs can allow tremendous possibilities for the improvement of the necessarily unique composite materials system. The present work deals with the fabrication of Cu-Fe/CNTs hybrid composites manufactured by powder metallurgy techniques. Copper powder with 10 vol. % of iron powder and different volume fractions of Multi-Wall Carbon Nanotubes (MWCNTs) were mixed to get hybrid composites. The hybrid composites were fabricated by adding 0.3, 0.6, 0.9, and 1.2 vol.% of MWCNTs to Cu- 10% Fe mixture using a mechanical mixer. The samples were compressed under a load of 700 MPa using a hydraulic press to compact the samples. Sintering was done at 900°C for 2 h at 5ºC/min heating rate. The microscopic structure was studied using a Scanning Electron Microscope (SEM). The effect of CNTs on the mechanical and wear properties, such as micro-hardness, dry sliding wear, density, and porosity were studied in detail. The wear tests were carried out at a fixed time of 20 minutes while the applied loads were varied (5, 10, 15, and 20 N). SEM images revealed that CNTs were uniformly distributed with relative agglomeration within the Cu/Fe matrix. The results showed that the hardness, density, and wear rates decreased while the percentage of porosity increased with increasing the CNT volume fraction. Furthermore, the wear rate for all the CNTs contents increased with the applied load.

Published: March 2020

The current research presents an overall performance-based analysis of Trihexyltetradecylphosphonium Chloride [[CH3(CH2)5]P(Cl)(CH2)13CH3] ionic fluid mixed with organic coconut oil (OCO) during turning of hardened D2 steel. The application of cutting fluid on the cutting interface was performed through Minimum Quantity Lubrication (MQL) approach keeping an eye on the detrimental consequences of conventional flood cooling. PVD coated (TiN/TiCN/TiN) cermet tool was employed in the current experimental work. Taguchi’s L9 orthogonal array and TOPSIS are executed to analysis the influences, significance and optimum parameter settings for predefined process parameters. The prime objective of the current work is to analyze the influence of OCO based Trihexyltetradecylphosphonium Chloride ionic fluid on flank wear, surface roughness, material removal rate, and chip morphology. Better quality of finish (Ra = 0.2 to 1.82 µm) was found with 1% weight fraction but it is not sufficient to control the wear growth. Abrasion, chipping, groove wear, and catastrophic tool tip breakage are recognized as foremost tool failure mechanisms. The significance of responses have been studied with the help of probability plots, main effect plots, contour plots, and surface plots and the correlation between the input and output parameters have been analyzed using regression model. Feed rate and depth of cut are equally influenced (48.98%) the surface finish while cutting speed attributed the strongest influence (90.1%). The material removal rate is strongly prejudiced by cutting speed (69.39 %) followed by feed rate (28.94%) whereas chip reduction coefficient is strongly influenced through the depth of cut (63.4%) succeeded by feed (28.8%). TOPSIS significantly optimized the responses with 67.1 % gain in closeness coefficient.

Objective

Co-aggregation of autoimmune diseases is common, suggesting partly shared etiologies. Genetic factors are believed to be important, but objective measures of environmental vs heritable influences on co-aggregation are absent. With a novel approach to twin studies, we aimed at estimating heritability and genetic overlap in seven organ-specific autoimmune diseases.

Design

Prospective twin cohort study.

Methods

We used a cohort of 110 814 twins to examine co-aggregation and heritability of Hashimoto’s thyroiditis, atrophic gastritis, celiac disease, Graves’ disease, type 1 diabetes, vitiligo and Addison’s disease. Hazard ratios (HR) were calculated for twins developing the same or different disease as compared to their co-twin. The differences between monozygotic and dizygotic twin pairs were used to estimate the genetic influence on co-aggregation. Heritability for individual disorders was calculated using structural equational modeling adjusting for censoring and truncation of data.

Results

Co-aggregation was more pronounced in monozygotic twins (median HR: 3.2, range: 2.2–9.2) than in dizygotic twins (median HR: 2.4, range: 1.1–10.0). Heritability was moderate for atrophic gastritis (0.38, 95% CI: 0.23–0.53) but high for all other diseases, ranging from 0.60 (95% CI: 0.49–0.71) for Graves’ disease to 0.97 (95% CI: 0.91–1.00) for Addison’s disease.

Conclusions

Overall, co-aggregation was more pronounced in monozygotic than in dizygotic twins, suggesting that disease overlap is largely attributable to genetic factors. Co-aggregation was common, and twins faced up to a ten-fold risk of developing diseases not present in their co-twin. Our results validate and refine previous heritability estimates based on smaller twin cohorts.

Comparison of the accuracy of intraoral scanning systems with conventional impression in dentate patient
Authors: ALSAYED İmadettin , ASLAN Yılmaz Umut
Published: March 2020

Background: Over the last years, different intraoral scanning systems for direct digitalization have been introduced to the dental market. However, the accuracy of these scanners is variable, and little information is available. The aim of this in vivo study was to compare the accuracy of two intraoral scanning systems and the difference between upper and lower jaw on the accuracy.Methods:10 patients with full dentition received one conventional impression with polyvinyl siloxane(Elite HD+, Zhermack SpA, Italy)and three scans with CEREC OC (Sirona Dental Systems, Sirona, Bensheim, Germany) and Straumann CARES IOS (Intra oral Scanner, Basel, Switzerland)for upper and lower jaw. The conventional impresions were poured and the casts made from it were scanned and used as the reference model  to evaluate precision and trueness of intraoral scanning virtual models provided by each system. Digital models were analyzed with a software (Geomagic Control;Geomagic, Morrisville,USA).Results:The trueness value was 99.88±42.56μmin upper jaw and 82.6±26.81 μmin lower jaw for CEREC OC, and 105.53±25.49 μmin upper jaw,and 109.56±36.84 μmin lower jaw for CARES IOS. The differences between two systems were not statistically significant (P>0.05), but statistically significant difference was found in the precision (P<0.05). CEREC OC showed higher value in both upper and lowerjaws.Conclusion:CEREC OC was more precise than CARES IOS and at the similar level of trueness. No statistically significant difference was found between upper and lower jaws in both systems.Key Words: Intraoral scanning, STL, Accuracy, CAD/CAM

Published: March 2020

Objective: Pediatric primary cardiac tumor is an extremely rare disease. The tumor can extend into the conduction system and cause malignant arrhythmias. We retrospectively reviewed 6 consecutive cases of children with primary cardiac tumor that manifested as rhythm disturbance.
Methods: In our center, 6 children were enrolled from October 2009 to August 2016. Detailed operative data and follow-up information were comprehensively collected and statistically analyzed.
Results: The patients were ages 1 to 16 years and weighed 7.9 to 44.5 kg. Preoperative ventricular tachycardia was present in 3 patients, frequent ventricular ectopic beats in 1 patient, supraventricular tachycardia in 1 patient, and atrial flutter in 1 patient. All 6 patients underwent a complete tumor resection. The tumors were localized in the left ventricular free wall (3 patients), left ventricular outflow tract (1 patient), left atrium (1 patient), and right atrium (1 patient). One patient received 2 radiofrequency ablation procedures before tumor resection. Postoperative sick sinus syndrome occurred in 1 patient because the tumor infiltrated the sinoatrial node. Tumors from 2 patients were pathologically diagnosed as fibroma and 4 as rhabdomyoma. Reoperation of mitral valve repair was performed in 1 patient 1 year after tumor resection. The mean (± SD) follow-up time was 63.7 ± 31.4 months, and all children were well, with Ross functional classification I and no signs of recurrence or metastasis.
Conclusions: In conclusion, cardiac tumor is a rare but nonneglectable reason for arrhythmia, and surgical resection is the optimal procedure, with satisfactory results.
La gestión de recursos humanos en contextos de individualización
Authors: Vesga Rodríguez Juan Javier
Published: March 2020

La sociedad actual y el mundo del trabajo han sufrido procesos de transformación caracterizados por una tendencia hacia la individualización en las relaciones y la fragilización de los vínculos humanos. Este contexto demanda para las organizaciones retos importantes para la gestión de recursos humanos, debido a que se deben replantear las estrategias y políticas dirigidas a la gestión de personas basada en los colectivos, para remplazarlas por prácticas de gestión individualizadas que respondan a las características actuales de las relaciones de trabajo. En este artículo se proponen un conjunto de reflexiones sobre las implicaciones en la gestión de recursos humanos derivadas de los procesos de individualización y se sugieren algunas alternativas como los contratos idiosincrásicos, el liderazgo individualizado y la gestión de los contratos psicológicos como formas más efectivas de gestionar los recursos humanos en las organizaciones en contextos de individualización.
Heritage and Patrimony of the Peasantry: an analytical framework to address rural development
Authors: Pachón-Ariza Fabio , Bokelmann Wolfgang , Ramírez-Miranda César
Published: March 2020

The term “rural development” is exceptionally multifaceted, which makes it difficult to define. This and other features make it a ‘wicked problem’, which means the consequences of ruraldevelopmental problems can create other complications. To date, the important discussion of rural development has dealt with productivity and economic concerns. This discussion has many crucial aspects such as the environment, infrastructure, and respect for fundamental rights. This paper describes the ‘Heritage and Patrimony of the Peasantry’ as an alternative analytical framework for addressing rural development. This analytical framework takes important topics from other rural development perspectives (primarily focused on food sovereignty principles). The heritage and patrimony of the peasantry framework moves away from the market point of view, which converts everything into an asset that can be marketed, and utilizes other sources of heritage. The peasantry has seven kinds of ‘heritages’ or ‘patrimonies’: natural, cultural, economic, physical, social, institutional, and human. These heritages or patrimonies are the bases of construction for a decent standard of living which will accomplish full rights for all rural inhabitants, i.e. rural development.

There is an increasing interest in the development of uchuva (Physalis peruviana L.) cultivars adapted to greenhouse farming. Sexual behavior makes it difficult to obtain uniform commercial uchuva cultivars by conventional breeding methods. Mutations induced by gamma rays is an alternative approach. M1 plants derived from 14 irradiation 60Co doses, from 0 to 275 Gy, that were applied to uchuva seeds were evaluated. Recorded data included days to first flower and growth dynamics (four to seven samplings) of morphological traits (plant height, stem diameter, basal stems) and reproductive traits (floral buds, flowers and green fruits). Treatments were distributed in a completely randomized blocks experimental design with six replications, in a greenhouse. The experimental unit was a single M1 plant. Statistical differences were found for irradiation doses, growth samplings, and its interaction. Growth dynamics results indicate that all traits showed a linear increase with plant age (R2 = 0.92* to 0.98**), but the effect of the irradiation doses on morphological and reproductive traits was no linear. Irradiation reduced plant height by 79%. M1 plants developed from irradiated seeds at doses of 125, 175 and 200 Gy showed greater stem diameter, with more basal stems, floral buds, flowers and green fruits than the control. It is concluded that intermediate irradiation doses had a stimulating effect on vegetative growth and fruiting traits of M1 uchuva plants.

Published: March 2020

Hyacinths are used in flowerbed in cities. Plants are exposed to difficult urban conditions prevailing in winter, including notably to soil salinity resulting mainly from the use of sodium chloride. The aim of the study was analysed the response of Hyacinthus orientalis ‘Delft Blue’ to increased concentrations of sodium chloride in the soil. Pots with bulbs were each treated with 100 cm3 of NaCl aqueous solution at a concentration of either 10 g .dm-3 (dose level 1) or 20 g. dm-3 (dose level 2). Pots were irrigated with the NaCl aqueous solution in September or in January of the following year. After keeping the bulbs at a cool temperature for 12 weeks, the plants were grown in a greenhouse where they were assessed in terms of growth parameters and free proline content. The obtained results showed that the growth and the ornamental qualities of Hyacinthus orientalis ‘Delft Blue’ after treatment with sodium chloride were sufficient for recommending this plant for growing in flower beds exposed to salinity of 6.1-8.6 g dm-3. The leaf greenness index and proline content (in the second season) were greater and the length of forcing period was longer (in the second season), when the sodium chloride was applied to the soil on the day of planting bulbs.

Published: March 2020

Circadian clock is usually involved in many physiological processes of plants, including responses to abiotic stress, whilst pseudo-response regulator 7 (PRR7) gene is the main component of the circadian clock. In this study, the cDNA of the PRR7 gene was obtained from trifoliate orange (Poncirus trifoliata). Based on the sequence analysis, the PtPRR7 gene had an open reading frame of 2343 bp, encoded 780 amino acids, and contained proteins of the REC and CCT domains. Subcellular localization indicated that PtPRR7 was mainly localized in the nucleus and a small amount of cytoplasm. qRT-PCR analysis revealed the highest expression level of PtPRR7 in roots than in both shoots and leaves. The PtPRR7 gene during 24 hours of soil water deficit exhibited a circadian rhythmic expression pattern: the expression peak at 9:00 am in leaves and at 21:00 pm in roots. Drought treatment affected PtPRR7 gene expression. Such data provide important references for understanding the characteristics of PtPRR7 gene in citrus plants.
Assessing the effects of in vitro imposed water stress on pineapple growth in relation to biochemical stress indicators using polynomial regression analysis

Published: March 2020

Knowing the mechanisms that operate under water stress in commercial crops, particularly those that can affect productivity, such as phenolic or cell wall metabolism, is becoming increasingly important in a scenario of global climate change. However, our understanding of how to analyse statistically the relationships between these commonly used biochemical markers of water stress and growth in crops like pineapple, needs to be improved. In the present work, we have addressed the question of whether polynomial regression analysis can be used to describe the influence of selected plant metabolites (chlorophylls, carotenoids, phenolics and aldehydes) on shoot biomass, in response to a mannitol-induced water stress in temporary immersion bioreactors (TIBs). Polynomial regression analysis has been applied to investigate plant stress responses in many species but is very seldom used in in vitro screening studies. Here, the relationship between biochemical indicators (x; independent variable) and shoot growth (y; dependent variable) has been characterised, with y modelled as an nth degree polynomial in x. This statistical approach accommodated for the non-linear (curvilinear) relationships between variables, and the results showed that shoot biomass was negatively, and significantly correlated with soluble phenolics, cell wall-linked phenolics and other aldehydes (characterised by “High” R2 values).

The present research aimed at screening various soils within Ilorin metropolis for antibiotic producing actinomycetes. The objectives of the study were to determine physiochemical parameters of soils, the occurrence of actinomycetes in soils, antibacterial potentials and identity of isolates. Soil parameters such as pH, temperature, moisture, organic matter and soil type were evaluated following standard procedures. Selective isolation to determine the occurrence of actinomycetes was performed by soil dilution using pour plate technique on starch casein agar. Preliminary antibacterial screening against 10 clinical test bacteria was performed using cross streak method. All isolates were initially identified based on morphological and biochemical characteristics, while the most bioactive isolates were further identified by molecular means. The soils were alkaline, with temperatures between 29 °C and 31 °C, moisture was in range of 0.72 ± 0.07c and 6.62 ± 0.42b. Highest organic matter content was 32.13 ± 0.20a with soil types mostly loamy and sandy loam. Ten actinomycetes (SM1 - SM10) were isolated, with the most frequently occurring isolate being SM3 and SM5 (16.7%). SM5 was the most active, inhibiting 9 out of 10 tests, with the highest inhibition against Staphylococcus aureus 25923 (24 mm ± 0.15a). All isolates were identified as Streptomyces by morphology and biochemical tests. Based on nucleotide similarity searches and phylogeny, two bioactive Streptomycetes were suggested as novel strains and thus named as Streptomyces bottropensis UIL RNA (SM5) and S. flavoviridis UIL RNA(SM7), which may serve as promising sources of antibiotics. Actinomycetes from Ilorin metropolis demonstrated broad spectrum of antibacterial activity against clinical test bacteria.

This study was conducted to investigate the in vitro callus induction and rapid shoot regeneration potential in Enterolobium cyclocarpum, a plant native to central Mexico but widely introduced into Africa. The leaf, stem and nodal explants of E. cyclocarpum were cultured on full strength Murashige and Skoog (MS) medium supplemented with different concentrations of Cytokinins - Benzyladenine (BA) and/or Kinetin and Auxins - Naphthalene acetic acid (NAA) and/or 2,4-Dichlorophenoxylacetic acid (2,4-D) each alone and in combination.  The leaf explants did not respond to these treatments.  The Nodal explants were best for caulogenesis, while the explant responses were in the order- nodal > stem > cotyledon for callogenesis in MS medium supplemented with BA and/or Kin combined with NAA and/or 2,4-D. The varied combinations induced white compact callus.  The highest callus production was observed on MS medium supplemented with 2.7 µM NAA + 2.2 µM BA and 5.4 µM NAA alone.  Nodal and cotyledon explants developed callus and multiple shoots on MS supplemented with a combination of cytokinin (BA and/or Kin.) and auxin (NAA and/or 2,4-D). The maximum number of 3.98 ± 0.37 and 2.1±0.11 shoots/explants were recorded for nodal and cotyledon explants on MS medium supplemented with a combination of 8.8 µM BA+2.7 µM NAA and 2.2µM BA+2.7 µM NAA respectively.  On the basal medium, 10% of the excised shoots rooted successfully. Thus, this in vitro method can be exploited for conservation and mass propagation of this fast timber yielding tree and also utilized for embryogenesis studies.

ABSTRACT Background: Hepatectomies promote considerable amount of blood loss and the need to administrate blood products, which are directly linked to higher morbimortality rates. The blood-conserving hepatectomy (BCH) is a modification of the selective vascular occlusion technique. It could be a surgical maneuver in order to avoid or to reduce the blood products utilization in the perioperative period. Aim: To evaluate in rats the BCH effects on the hematocrit (HT) variation, hemoglobin serum concentration (HB), and on liver regeneration. Methods: Twelve Wistar rats were divided into two groups: control (n=6) and intervention (n=6). The ones in the control group had their livers partially removed according to the Higgins and Anderson technique, while the rats in the treatment group were submitted to BCH technique. HT and HB levels were measured at day D0, D1 and D7. The rate between the liver and rat weights was calculated in D0 and D7. Liver regeneration was quantitatively and qualitatively evaluated. Results: The HT and HB levels were lower in the control group as of D1 onwards, reaching an 18% gap at D7 (p=0.01 and p=0.008, respectively); BCH resulted in the preservation of HT and HB levels to the intervention group rats. BCH did not alter liver regeneration in rats. Conclusion: The BCH led to beneficial effects over the postoperative HT and serum HB levels with no setbacks to liver regeneration. These data are the necessary proof of evidence for translational research into the surgical practice.
Secagem da polpa de jambolão (Syzygium cumini) em secador de leito de jorro: efeito da clara de ovo como agente carreador de secagem na qualidade do produto
Authors: Soares Andressa Costa , Pereira Nádia Rosa
Published: March 2020

Resumo Este trabalho reporta a avaliação da secagem e das propriedades do pó de polpa de jambolão produzido com mistura de maltodextrina 10DE-clara de ovo, em diferentes proporções, como agentes carreadores de secagem (correspondendo a 19,5% da formulação). A secagem foi realizada em leito de jorro (temperatura do ar de 70 °C, vazão de 2,9 kg/min e vazão de alimentação de 11 g/min) com polietileno de baixa densidade como inerte (550 g), sendo avaliada a influência da composição da mistura de maltodextrina-clara de ovo na eficiência de secagem e nas seguintes propriedades do pó: umidade, atividade de água, diâmetro da partícula, densidade bulk, molhabilidade, solubilidade, higroscopicidade, cor e retenção das antocianinas. Produtos com maior teor de clara de ovo apresentaram maior retenção de antocianinas (79%) e menor tempo de molhamento (6 min) em relação à maltodextrina. Por outro lado, apresentaram redução de 31% no diâmetro médio e aumento de 35% na higroscopicidade dos pós, e menor rendimento de produção de pó na secagem (27%). A densidade bulk aumentou entre 14% e 19% após armazenamento por 40 dias, o que pode estar relacionado com alterações nas propriedades físicas do material, principalmente a molhabilidade e a higroscopicidade. Conclui-se que o uso da clara de ovo como agente carreador em combinação com maltodextrina na secagem de jambolão pode ser viável para obtenção de produto em pó com maior retenção de antocianinas e maior teor de proteínas.

Authors: Oliveira Iuri Magalhães de Alencar , Castro Ruann Janser Soares de
Published: March 2020

Abstract Kefir, a consortium of acetic and lactic bacteria and yeasts, is versatile for biotransformation of vegetable substrates and may improve their bioactive properties. Lentil is a legume rich in vitamins, minerals, complex carbohydrates and proteins, making it an excellent substrate for fermentation and obtaining bioactive molecules. We report the effect of different process variables on antioxidant properties of lentil extracts obtained using kefir as a biotransformation agent and experimental design. The results showed that the factors agitation (rpm) and incubation temperature exerted significant effects. Incubation temperature of 28 °C and agitation of 75 rpm were the most suitable conditions for kefir fermentation and maximizing the antioxidant properties of the fermented lentils. The highest antioxidant activities for fermented products were 4128.39, 35.87 and 23.20 μmol of Trolox equivalents per gram of sample (μmoL TE g-1) measured by Total Antioxidant Capacity, FRAP and DPPH-radical scavenging methods, respectively. Additionally, we detected that the initial fermentation times (in the first six hours) were enough to positively affect the antioxidant properties of the lentil extracts, reaching a percentage increase of up to 270% in the antioxidant activity of the fermented products in relation to those non-fermented samples.
