Published: October 2021

ABSTRACT Broccoli (Brassica oleracea var. italica) is one of the most important vegetables in the world and also shows important functional properties. The present study aimed to characterize 19 broccoli genotypes using biochemical traits (content of total phenolic compounds, total flavonoids and antioxidant activity) and AFLP (Amplified Fragment Length Polymorphism) molecular markers. The experiment was carried out in a greenhouse using a complete randomized block design with three replicates. The phenotypic data were subjected to analysis of variance (p≤0.05), Scott-Knott average clustering method (p≤0.05) and principal component analysis (PCA). Using molecular data, Ward’s hierarchical clustering, Bayesian clustering and principal coordinate analysis (PCoA) were performed. Molecular data showed genetic diversity among the genotypes (three groups), also a wide variability in the total phenolic compounds, total flavonoids content and antioxidant activity using FRAP method. HT3010, Hanabi and Bonanza genotypes showed desirable biochemical traits for the demanding functional food consumers, in addition to being promising genotypes to be exploited in plant breeding programs.

Published: October 2021

ABSTRACT This study aimed to evaluate strategies for growing pigeon pea and tephrosia intercropped with maize in different spatial arrangements for green manure in organic snap bean farming in succession. The experimental design was a randomized block, in a 2x3 + 1 factorial scheme, corresponding to the two species and the cropping system (monocropping; intercropping with sowing in the same row or between rows). The treatments consisted of pigeon pea and tephrosia monocropping, pigeon pea or tephrosia intercropped with maize in the same planting furrow, pigeon pea or tephrosia intercropped with maize between rows, and maize monocropping (control). After cutting the pre-crops, snap beans were sown. The authors verified that the introduction of shrub leguminous plants in intercropping did not interfere with the phytotechnical characteristics of maize. The tephrosia monocropping and the intercropping of this species with maize, regardless of sowing location, provided, respectively, the highest productivities of pods and dry beans of snap beans, compared with pigeon pea pre-cropping.

ABSTRACT The objective of this study was to evaluate the effect of calcium supplementation on saline water as a minimizing agent of saline stress in okra cultivars. The experiment was carried out in a greenhouse in Mossoró-RN using a completely randomized experimental design in a 2x5 factorial scheme with four replications. Two okra cultivars (Santa Cruz 47 and Valença) were tested fertigated with five fertigation managements [F1= irrigation with non-saline water (0.5 dS m-1) and fertigation with a standard dose of calcium (4,733.8 mg plant-1); F2, F3, F4 and F5= irrigation with saline water (3.5 dS m-1) and fertigation with increasing doses of calcium (4,733.8; 7,100.7; 9,467.7 and 11,834.5 mg plant-1, respectively)]. Plants were collected at 120 days after emergence and evaluated for growth variables (plant height, leaf number, stem diameter, leaf dry mass, stem, fruit and total) and yield (fruit number, average length of fruits, average diameter and yield). Cultivar Santa Cruz 47 presented the highest vegetative development but cultivar Valença was earlier and presented the largest number of harvests (19), allowing more harvested fruits (27 fruits per plant) and the highest yield (659 g plant-1). The cultivars were not affected by the saline level and showed little response to extra calcium fertilization.

ABSTRACT The aim of this study was to evaluate productive and physiological traits of basil cv. Italiano Genovese grown in nitrogen-fertilized soil. We studied five doses of nitrogen (25, 50, 75, 100 and 125 kg ha-1), in urea form. The experimental design was completely randomized, with four replicates. The maximum plant height was 79 cm, applying 65.7 kg ha-1 N. Shoot fresh and dry masses (814.1 g plant-1 and 111.4 g plant-1, respectively) and productivity (4.4 t ha-1) reached maximum values at 86.2; 80.2 and 82.5 kg ha-1 N, respectively. The highest N content in plant shoot was 26.1 g kg-1 at 125 kg ha-1 N. Photosynthesis and instantaneous carboxylation efficiency obtained maximum responses at doses of 85.3 and 83.3 kg ha-1 N, respectively. Stomatal conductance and transpiration increased with N additional rates.

Im 15. Jahrhundert verfügten die Europäer über das notwendige geographische und navigatorische Wissen, um die Weltmeere zu erkunden. Vor allem waren die technischen Voraussetzungen für überseeische Entdeckungsfahrten gegeben. Diese Unternehmungen unterschieden sich von den vorangegangenen, eher zufälligen Kontakten einzelner Europäer mit nichteuropäischen Zivilisationen in aller Regel dadurch, dass ihnen ein – wenngleich wenig ausgefeilter – Plan zugrunde lag, der die Erlangung ökonomischer Vorteile, die Erweiterung politischer Einflusssphären und schließlich auch die Fortsetzung des Kampfes gegen die Ausbreitung des Islams vorsah. Infolgedessen überzogen die Europäer die Welt mit einem dichten Netz von maritimen Handels- und Verkehrswegen zum Transport von Menschen, Gütern und Informationen. Über dieses Netz wurden europäische rechtliche Normen und moralische Werte in alle Teile der Welt transferiert, was die weitere Entwicklung der davon betroffenen Regionen nachhaltig bis in die Gegenwart beeinflusste.
Der Staat als Kolonialware. Ein Gespräch
Authors: Pahuja Sundhya
Published: October 2021

Die Pandemie strapaziert die Lieferketten. Lockdowns und Grenzschließungen, Quarantäne und Insolvenzen verlangsamen die globale Warenzirkulation. Und manches Handelsgut kommt nie an. In Lieferschwierigkeiten geriet im vergangenen Sommer auch Sundhya Pahuja, die uns für dieses Heft ein gemeinsam mit Jeremy Baskin verfasstes Stück über eine besondere Kolonialware und deren vielschichtige ökonomische und kulturelle Kontexte zugesagt hatte. Die durch die Pandemie ausgelöste Krise des australischen Universitätssystems führte auch an der Universität Melbourne, an der Pahuja Völkerrecht lehrt, zu Umstrukturierungen, die weiter andauern. Keine Zeit, um in Ruhe über koloniale Güter und ihre verschlungenen Wanderwege nachzudenken. Gerade in der gegenwärtigen Ausnahmesituation kommt es aber besonders auf die langen Leitungen an, die verlässlichen Verbindungen zwischen Menschen und Kontinenten.

Kolonialwaren haben ihren festen Platz in den Schubladen unseres Gedächtnisses. Jahrzehntelang gehörte die Kolonialwarenhandlung zum Bild deutscher Städte, bis sie in den 1970er Jahren von Supermarktketten verdrängt wurde. Erlesenes und Alltägliches, Kakao, Tabak, Gewürze und Zucker wurden hier feilgeboten, später auch alle möglichen anderen Waren des täglichen Bedarfs. Ein sehr deutscher Erinnerungsort des Kolonialen, den der Postkolonialismus nie erreichte. Ein nostalgischer Rückzugsort womöglich, an dem sich bei einem Kännchen Plantagen-Kaffee mit Hochland-Aroma gepflegt über gemeinsame und geteilte Kolonialvergangenheiten, colonial stories und shared histories, parlieren lässt – natürlich auch, so gebieten es guter Ton und geopolitisches Kalkül, mit dem ein oder anderen Vertreter vormals ausgebeuteter Gemeinschaften des Globalen Südens?

Traumchemie. Wie Yvan Goll Straßburg wiedersah
Authors: Bürger Jan
Published: October 2021

Nichts hatte sich Yvan Goll in Brooklyn sehnlicher gewünscht als das Ende des Zweiten Weltkriegs. Dennoch fiel es dem Lyriker, Dramatiker und Erzähler schwer, im Juni 1947 nach Europa zurückzukehren. In dieser Hinsicht ging es ihm nicht anders als Alfred Döblin, Bertolt Brecht oder Thomas Mann – als all seinen deutschen Freunden und Bekannten, die in den USA Zuflucht gefunden und so den Nationalsozialisten entkommen waren. Die Verfolgungen und Gefechte gehörten der Vergangenheit an, nun stand ihnen die Remigration bevor, der Neuanfang in einer Welt, die seit ihrer Flucht von Grund auf erschüttert, wenn nicht für immer zerstört worden war. Aber gehörte Yvan Goll überhaupt zur Gruppe der deutschsprachigen Emigranten? Die Frage nach seiner Nationalität hatte er doch schon 1919 weit von sich gewiesen. Als es darum ging, für Kurt Pinthus’ Menschheitsdämmerung eine der üblichen Kurzbiografien einzureichen, nutzte Goll, der bürgerlich Isaac Lang hieß, die Chance, mit den Konventionen zu brechen.
Zukunft als Vergangenheit. Über Zangenbewegungen im zeitgenössischen Erzählen
Authors: Kukkonen Karin
Published: October 2021

Es scheint zu Ende zu gehen mit der Geschichte. Francis Fukuyama konstatierte vor fast dreißig Jahren das «Ende der Geschichte», und François Hartog spricht generell von einem Ende des «Regimes der Historizität». Mit diesen Zeitdiagnosen geht ein Problem für das zeitgenössische Erzählen einher: Das Selbstverständnis des Westens als einer Kontinuität, die sich aus der Vergangenheit speist, und die stets auf dem Weg in eine (vermutlich bessere) Zukunft ist, hat sich aufgelöst. Die Zeitläufte sind angehalten, und die Gegenwart übernimmt. Diese Gegenwart charakterisiert Hartog über die «Tyrannei des Augenblicks» einerseits, und durch ein «Jetzt», in dem man «auf der Stelle zu treten scheint».
Kritik der Kritik. Zur Entleerung des Begriffs
Authors: von Rahden Wolfert
Published: October 2021

Die Wucht der kantischen Kritik nannte Moses Mendelssohn «alles zermalmend», und sie stürzte noch Kleist in eine existenzielle Krise. Die Sagazität dieser Vernunftkritik markierte einen erkenntnistheoretischen Einschnitt in der Spätaufklärung. Von Kants drei «Kritiken» löste bei vielen Zeitgenossen in erster Linie die Kritik der reinen Vernunft jenen skandalösen «Choc» aus, da sie nicht nur eine vermeintlich gesicherte Realitätserkenntnis infra-ge stellte, sondern auch die Architektur der traditionellen Gottesbeweise zum Einsturz brachte. Auch wenn Kant später in der Kritik der praktischen Vernunft Gott als Postulat der praktischen Vernunft wieder diskret an der Hintertür in sein Theoriegebäude hereinbat, nachdem er ihn zuvor spektakulär zur Vordertür hinausgeworfen hatte – die Erschütterung minderte das kaum.
Keine gefährliche Begegnung mit Ernst Jünger

In einem Brief vom 11. Januar 1955 machte Hans Paeschke, einer der beiden Herausgeber des Merkur, Jürgen Habermas Vorschläge für weitere Beiträge in der Zeitschrift. Einige Monate zuvor war hier dessen erster Aufsatz Die Dialektik der Rationalisierung erschienen, in dem er auf der Basis industriesoziologischer Studien den Wandel der Entfremdung durch neue Formen der Produktion und Konsumption im fortgeschrittenen Kapitalismus diskutiert. Am Ende des Briefes schreibt Paeschke: «Ich überlege, ob wir Sie nicht anlässlich des 60.Geburtstags von Ernst Jünger am 29. 3. zu einer Äußerung bewegen sollten, bewusst vom Standpunkt Ihrer Generation aus gesagt: was erhofften wir uns von ihm, was geben seine Traktate nach dem Krieg, wie und wo stehen diese im Vergleich zu seinem früheren Werk und was haben sie den Jüngeren heute zu sagen?»
Ein politischer Denkzettel aus Chicago
Authors: Bluhm Harald
Published: October 2021

Ein politischer Einspruch erreichte Jürgen Habermas in den frühen Sechziger Jahren aus Chicago. Am 27. April 1964 bedankte sich Leo Strauss bei Habermas für die Zusendung seiner sozialphilosophischen Aufsatzsammlung Theorie und Praxis. Strauss war eigentlich weniger ein Denker der Praxis – als der Theorien und Ideen; wie nur wenige politische Philosophen der Nachkriegszeit dachte er allen modernen turns zum Trotz selbstbewußt aus dem Geist der alt-europäischen Überlieferung. Es war jene alte Welt des Naturrechts und der klassischen Lehre der Politik, gegen die Habermas seine moderne Sozialphilosophie als neue zeitgemäße Wissenschaft konturierte.

In Adornos Minima Moralia gibt es einen Abschnitt über das «tough baby», den Typ des «gut Aussehenden, der im Smoking, spät abends, allein in seine Junggesellenwohnung kommt, die indirekte Beleuchtung andreht und sich einen Whisky-Soda mischt».Für diesen idealtypischen Leser erfand der abgebrochene Soziologiestudent Hugh Hefner den Playboy, dessen erstes Heft 1953, zwei Jahre nach Adornos Bestandsaufnahme des beschädigten Lebens erschien. Man könnte eine eigene Miniatur der Dialektik der Aufklärung aus der Tatsache gewinnen, dass Adorno an dieser wie an anderen Stellen seiner Homophobie die Zügel schießen lässt (das «tough baby» als verdrängter Homosexueller), während Hefner mit seinem Unterhaltungsmagazin 1955 den ersten von zahlreichen Skandalen entfesselte, als er mit einer dystopischen Story von Charles Beaumont gegen die Diskriminierung von Schwulen Stellung bezog.

Ach, Ästhetik!

Published: October 2021

In seinem Stück über das Nachleben Lessings stellte Friedrich Schlegel klar, was von diesem Meister der Aufklärung geblieben sei: nicht das Werk, sehr wohl aber die historische Persönlichkeit: «Er selbst war mehr wert, als alle seine Talente.» Auch wenn man besser von Lessings Werk denkt, als Schlegel es tat, bleibt die Unterscheidung hilfreich zur Beschreibung derjenigen, die über beides verfügen. Werk und Persönlichkeit bedürfen dabei beide nolens volens einer Ästhetik, unvermeidlich einer unterschiedlichen. Dies gilt auch für die einzige öffentliche Figur der bundesdeutschen Geschichte, die ein theoretisches Werk vorzuweisen hat: Jürgen Habermas.
How many thick disk subsystems are there in the Milky Way Galaxy?
Authors: MARSAKOV V. A. , GOZHA M. L. , KOVAL V. V.
Published: October 2021

It was shown that stellar populations of the Galaxy with the thick disk kinematics, namely globular clusters, field RR Lyrae variables (lyrids), and nearby field F - G stars, have different chemical compositions. Based on the analysis of the nature of the dependencies of [alpha/Fe] on [Fe/H] for these objects, it was concluded that the thick disk subsystem in the Galaxy is composite, and at least three components independently exist inside it. The oldest subsystem consists of the metal-rich globular clusters which were formed from a single protogalactic cloud shortly after onset of the explosions of type Ia supernova in it. Then a subsystem of the field thick disk stars was formed as a result of the "heating" of the stars of the primary thin disk already formed in the Galaxy by a rather massive dwarf satellite galaxy which fell onto the Galaxy. And, finally, the subsystem of field stars (including the lyrids) with the kinematics of not only the thick, but even the thin disk that fell onto the Galaxy from this captured satellite galaxy.

Published: October 2021

In order to improve the properties of sintered MgO (80 % precipitation) obtained from seawater, an investigation was carried out with (0, 1, 2) w/% of nano-TiO2 and micro-TiO2 additions during sintering at a temperature of 1500 °C (1 h and 2 h). The effects of the TiO2 addition on its microstructural properties, density, porosity and chemical composition after sintering were observed. The SEM/EDS analysis confirmed the formation of a homogeneous microstructure composed mainly of periclase grains and well-distributed secondary phases. CaTiO3 and MgTiO4 are predominantly located at the inter- and intra-periclase grain boundary surfaces during cooling. The microstructure of the MgO samples with the addition of nano-TiO2 become more compact, having a positive impact on the porosity and density of the samples. The addition of 1 w/% of nTiO2 represents the optimal amount for the improvement of the properties of the MgO samples (80 % precipitation) obtained from seawater.

Published: October 2021

Treatment of the sludge from water-purification plants is becoming more and more urgent due to the inability to increase its storage area. To avoid CO2 emissions, the use of non-Portland cement binders is recommended. The application of geopolymerization of waste sludge (WS) from water-purification plants is a novel solution. Curing conditions including high temperature, pressure or microwaves enhance the formation of geopolymer bonds. This paper presents the results of a research on the treatment of the WS of the Thu Duc water-purification plant (Vietnam) with the geopolymerization method. Solid phases were prepared by mixing the WS and fly ash (FA). The FA proportions of the solid phases were (10, 40, 70) w/%. The alkali-activated solution (AAS) was a mixture of a 40 w/% NaOH 6M solution and 60 w/% water glass (WG: Na2O.nSiO2 with n = 1.75 and volumetric density r  = 1.40 kg/L). The geopolymer materials were mixtures containing an 80 w/% solid phase and a 20 w/% liquid phase of the AAS. Geopolymer samples were formed in a cylindrical steel mold with a diameter of 10 mm at a high pressure. The samples were cured in a 112 W microwave oven for 30 s or in a dryer at 110 °C for 24 h. The compressive strength and volumetric density of both sample groups were determined and compared to each other. The formation of geopolymer bonds was investigated using XRD, FTIR and SEM.

Published: October 2021

The influence of chemical composition and heat treatment on the mechanical properties and formability of the selected commercial aluminium alloy EN AW 5454 was investigated. The main properties of alloy 5454 from the AA 5xxx series are very good corrosion resistant and has good formability. From the cast slab a 50 mm thick slice was taken in the width cross section in the slab centre. One half of the slice was homogenised for 10 hours at a temperature of 530 °C. The cast and homogenised samples were investigated using light and scanning electron microscopy. For the study of the influence of the heat treatment, samples in the as-cast state were annealed in the laboratory furnace at a temperature of 530 °C for 4, 6, 8, 10 and 12 hours. To study the influence of chemical composition, four different samples were prepared: the first without additions, the second with an addition of 1 wt% Mn, the third with 3 wt% Mg and the fourth with an addition of both elements, Mn and Mg. The XRF analyses confirmed the desired chemical composition of all four produced alloys. Half of each alloy’s sample was homogenised at the same temperature and time as the base alloy in the as-cast state. The hot deformation behaviour of the different alloys was investigated using cylindrical hot compression tests performed on a Gleeble 1500D thermo-mechanical simulator. By comparing flow curves a high influence of the thermo-mechanical parameters on the alloy formability can be seen. The alloy has good workability and with the addition of Mn and Mg, the stress values are higher than those of the base alloy.

Published: October 2021

A sulphide capacity prediction model of CaO-SiO2-MgO-Al2O3 slags has been developed based on the ion and molecule coexistence theory(IMCT). Sulphide capacity(Cs) of slag for blast furnace (BF) with high Al2O3 in the CaO-SiO2-MgO-Al2O3 system at 1773K were measured by applying slag-metal equilibrium method. The feasibility of the developed IMCT model is verified by the sulphide capacity measured in the experiment. Effects of R(w(CaO)/w(SiO2)), w(MgO)/w(Al2O3) and w(Al2O3) on sulphide capacity were discussed. There is a good linear relationship between the experimental value and the predicted value. Therefore, the theoretical model of ion and molecule coexistence can be used to calculate the sulphide capacity of CaO-SiO2-MgO-Al2O3 quaternary slag system. When w(Al2O3)=20% and w(MgO)/w(Al2O3)=0.5, the sulphide capacity of slag increased with the increase of R. When w(Al2O3)=20% and R=1.30, the sulphide capacity of slag increased with the increase of w(MgO)/w(Al2O3). When R=1.30 and w(MgO)/w(Al2O3)=0.4, the sulphide capacity of slag decreased with the increase of w(Al2O3).

Published: October 2021

The warm deformation behavior of 65Mn spring steel has been carried out by a thermomechanical simulator. The deformation temperatures are in the range of 550 ~ 700℃ and strain rates are in the range of 0.001 ~ 1 s-1. The deformation activation energy is calculated to be 486.829 KJ•mol-1. The strain compensated Arrhenius-type constitutive model was established. The relationship materials constants and strain were fitted with an 8th order polynomial.  It was found that the strain has a significant influence on the instability map. At the strain is 0.3, the optimum flow zone may take place with the deformation temperatures higher than 626 ℃ and strain rate in the range of 0.001 ~ 1 s-1.

Published: October 2021

The main objective of this study is to explore the influence and reflexes of urban and environmental legislation on the production, configuration, and distribution of urban open spaces. The work is based on the premise that, over the last years, legislation has played an important role in the composition of the urban spatial mosaic, especially regarding the need and obligation of all new lots to reserve, in the lottable land, a minimum percentage of open spaces, understood in this research as the road network, public recreation areas, permanent environmental protection areas, municipal easements and property easements. The object of this observation are the urban lots approved by the city of Uberlândia since 2000, a period in which several factors forced the city to adjust to the new urban development instruments and to the master plan, mainly the city’s rapid growth, also a result of the growth of the Brazilian real estate market. We applied the morphometric methodology, using the QGIS software to quantify open space and analyze measurements and rates of the morphological elements based on the legal parameters. The result was the identification of the way open spaces were designed in the analyzed projects, their spatial relations, morphological typology and distribution patterns, uncovering recurring patterns that characterize the landscape of many medium-sized Brazilian cities.

Tuberculosis (TB) due to Mycobacterium bovis is a wasting disease of animals with severe public health significance. Though widely diagnosed in cattle and the performance of Tuberculin Skin Test (TST) at different cut-off points compared in various environmental conditions, there is dearth of information with respect to TB in goats in Cameroon. This study estimated the prevalence of bovine TB in goats in Benuoe area of Cameroon, based on the performance of TST against detection of tuberculous-like lesions and acid-fast bacilli as gold tests. The study detected goat TB based on tuberculous-like lesions (27.87%), acid-fast bacilli (3.29%); and bovine TB positive reactions (12.28%, 95%CI: 9.19–15.95), (8.95%, 95%CI: 6.31–12.23) and (5.37%, 95%CI: 3.36–8.09) at Single intradermal cervical tuberculin (SICT) ≥2.5mm, ≥3mm, and ≥4mm and (2.30%, 95%CI: 1.06–4.32), (1.79%, 95%CI: 0.72–3.65) and (1.02%, 95%CI: 0.28– 2.60) at Single intradermal comparative cervical tuberculin (SICCT) ≥2mm, ≥3mm, and ≥4mm cut-off points, respectively. SICT and SICCT sensitivity (11.76%) against detection of tuberculous-like lesions was significantly lower [p<0.05] with slight agreements [Kappa=0.161] compared to sensitivity (100%) and perfect agreements [Kappa=1.00] against detection of acid-fast bacilli at these cut-offs. The Bayesian model revealed a goat TB prevalence of 18.41% (95%CI: 11.73–27.00) using SICT and 4.28 (95%CI: 1.26–8.60) using SICCT with the performance characteristic being higher for SICT than SICCT at ≥2mm cut-off. However, two-graph ROC (TG-ROC) analysis revealed that the optimal goat TB diagnosis with SICCT was at ≥2mm cut-off point. Many goat handlers were aware of health hazards of zoonotic TB but ignorant about goat TB and its possible zoonotic transmission to humans. The study reports the first comparative tuberculin skin test of goats in Benoue area of North-Cameroon and confirmed that zoonotic TB is a neglected health and production problem of goats in Cameroon that needs further investigated.

The World Health Organization (WHO) declared, on January 30, 2020, that the outbreak of the disease caused by the new Coronavirus (COVID-19) constitutes a Public Health Emergency of International Importance - the highest level of alert of the Organization, as provided for in the International Health Regulations. On March 11, 2020, COVID-19 was characterized by the WHO as a pandemic and since then the world has been going through an unprecedented period. The pandemic is interfering with all aspects of everyday life, especially in the area of ​​health. Surgical practice was directly affected by the suspension of elective procedures and the prioritization of urgent and emergency surgeries as a way to free up beds for patients infected with the disease. New coronavirus. The script for resumption of elective surgery after this COVID-19 pandemic must be progressive and cautious. Elective surgery should be performed in COVID-free facilities and the hospital stay should be as short as possible. For safety reasons, patients considered for surgery should be carefully selected according to status/exposure to COVID-19 infection, age, ASA physical status/risk factor classification system, socio-professional status and surgical indication. Therefore, in this study, we will demonstrate the positive impact on surgical resumption using a rapid recovery protocol combined with a minimally invasive technique (AMIS) for total hip arthroplasty during the period of worldwide pandemic for SARS-CoV-2.

Published: October 2021

Objetivo: Evaluar la asociación entre las redes sociales de amigos y la capacidad cardiorrespiratoria en estudiantes universitarios. Metodología: Estudio de corte, con muestreo aleatorio de cursos completos, por cada programa y semestre académico, con 475 participantes, realizado durante 2018. Se utilizaron mediciones de peso, talla, índice de masa corporal y encuesta para determinar el nivel de actividad física, las actividades sedentarias y las métricas de red social (como densidad de la red, centralidad de la red, popularidad social, miembro de grupos, proporción de amigos activos físicamente y proporción de amigos con alta capacidad cardiorrespiratoria). Resultados: Las variables de la red social presentan un comportamiento diferente según sexo. En las mujeres, respecto a la red social, aumentar 10 % la proporción de amigos activos físicamente incrementa 150 % la posibilidad de tener capacidad cardiorrespiratoria alta (OR: 2,50 IC:1,01-6,21); incrementar las relaciones sociales (centralidad de la red) disminuye la oportunidad de tener capacidad cardiorrespiratoria alta en 65 % (OR: 0,35, IC:0,19-0,65); tener alta popularidad social acrecienta en 120 % la oportunidad de tener capacidad cardiorrespiratoria alta (OR: 2,20, IC:1,07-4,55). En los hombres, no se encontró asociación entre las variables de la red social con la capacidad cardiorrespiratoria. Conclusiones: La capacidad cardiorrespiratoria es influenciada por la red social de amigos universitarios y su comportamiento difiere según sexo. La red social en la que se desenvuelven los sujetos es un medio en el que se comparten y trasmiten comportamientos saludables y no saludables.

Resultados: Se encontró que los recicladores presentaron mayor prevalencia de enfermedades dermatológicas en el examen físico y en antecedentes de salud, entre los cuales se identificó un 63,7 % con tres o más lesiones en piel (en contraste con un 16,6 % de los no recicladores), y pronunciados porcentajes en enfermedades infecciosas cutáneas: micosis (50 %) y de origen bacteriano (31,8 %). En antecedentes cutáneos, los recicladores resultaron con mayores proporciones en heridas por corte (59,1 %), forúnculos (59,1%), tunga penetrans (40,9 %), larva migrans cutánea (36,4 %), heridas infectadas por corte (27,3 %), fotodaño (22,7 %), tinea pedis (13,6 %) y heridas por punción de jeringa (9,1 %). Estos reportaron también mayores porcentajes respecto a frecuentes problemas respiratorios, gastrointestinales, cefaleas y dolores musculoesqueléticos. Se constataron insuficientes medidas de protección de seguridad y salud en los trabajadores dedicados a la actividad del reciclado.

Conclusión: Estos resultados sugieren un mayor potencial de exposición del grupo de recicladores a una variedad de fuentes de riesgos en salud relacionadas con las condiciones precarias de su actividad laboral, lo cual apunta a un desafío prioritario para la salud pública.

Stevia rebaudiana Bertoni is a plant species which is frequently used not only as a sweetener, but also for its antibacterial and antioxidant properties. Nowadays, there are a large number of studies on the antimicrobial and antioxidant activity of S. rebaudiana leaves, but there are almost no data about the antimicrobial and antioxidant potential of extracts from the other parts of S. rebaudiana. The aim of the present study is to provide data of the antibacterial and antioxidant potential of methanolic extracts from different parts of S. rebaudiana (flowers, leaves, stems, rhizomes, and tubers) cultivated in Bulgaria. Antibacterial activity of the extracts against Staphylococcus aureus, Bacillus cereus and Escherichia coli was evaluated by agar well diffusion method, rutin content - by HPLC method, total phenolic content and radical scavenging potential - by UV-Vis analysis. S. rebaudiana extracts demonstrated antibacterial activity mainly against S. aureus - flower extracts expressed the highest activity, followed by the leaf and stem extracts. Only flower and leaf extracts demonstrated very low antibacterial activity against B. cereus. S. rebaudiana extracts did not show any antibacterial activity against E. coli. Methanolic extracts of this plant are rich in antioxidants. The highest concentrations of rutin and total phenols were found in the rhizomes of the plants, followed by the leaves, tubers, flowers, and stems, which corresponded to the radical scavenging potential of the same plant part. Comparisons between Trolox equivalents and gallic acid equivalents in different parts of S. rebaudiana on one hand, and Trolox equivalents and rutin concentration on the other hand showed a positive dependence and high values of the Pearson correlation - 0.9612 and 0.9707, respectively. The most important part of S. rebaudiana with medicinal significance (the leaves) has both comparatively good antibacterial activity and high antioxidant content, although the flowers and rhizomes expressed higher antibacterial and antioxidant activity, respectively. The experimental results imply that the cultivation area and climatic conditions of Bulgaria are very suitable for cultivation of S. rebaudiana plants with high content of antioxidants.

Carbon fibre reinforced polymer composites (CFRP) is one of the common materials used in machining by various manufacturing industries. The most persistent challenges during the machining, both concerning the consistency of machined surfaces and the properties of the material, are the difficulties such as fibre pull-out, delamination, and decomposition of the material matrix. This preliminary research highlights the laser machining of thick CFRP using a fibre laser of more than 1 kW. Laser machining experiments have been conducted to examine the ability of the fibre laser machine to cut thick CFRP through their high-quality laser beams. Based on the results, the study showed how the heat affected zone can be reduced when the higher cooling period is used. The effects of modulated beam mode include substantial reductions in HAZ compared with other experimental results. In all experimental attempts, substantial damage has occurred. The results are important in assessing the relationship between laser machining parameters and cutting results.

Certain age hardenable alloys such as AA7475 cannot be joined with perfection using fusion welding techniques. This requires non-conventional welding technique such as friction stir welding process to join these ‘difficult to weld’ alloys. In this study, three different cooling conditions i.e. cryogenic, sub-zero, and zero-degree Celsius temperature conditions have been analyzed to understand its impact on the welding process. In-process cooling was found to behave effectively and also enhanced the mechanical properties of the welded joints. A stable microstructure was clearly seen in the images observed under the metallurgical microscope. The weld efficiencies were found to be good in each of the samples which are indicative of a strong metallic joint. The effective cooling conditions employed had an overall positive impact on the joint.
