TÍTULO: El contenido de la responsabilidad social desde la perspectiva jurídica.

 

RESUMEN: En el presente trabajo se analiza el contenido de la responsabilidad social (RS) desde una perspectiva jurídica y específicamente aplicado a las personas jurídicas del Derecho Privado. Para ello nos planteamos dos objetivos, de un lado delinear los caracteres generales que presenta el contenido, porque de ello se deriva la relación con el sistema jurídico. De otro lado, establecer el contenido mediante el análisis de un supuesto de aplicación de la RS, como es el caso de la cadena de suministro.

La metodología utilizada parte del marco de la Teoría Trialista del Derecho -desarrollada por Werner Goldschmidt- y se basa en el análisis del contenido que establecen las principales fuentes de la RS, esto es los códigos de conducta surgidos de organismos internacionales, los códigos de conducta unilaterales y los acuerdos marco transnacionales (AMT). Los datos serán tomados de fuentes indirectas que arrojan resultados en base a estudios de tipo empírico. Asimismo, nos valemos de doctrina jurídica e investigaciones de otras disciplinas.

 En conclusión el estudio del contenido de la RS revela que el mismo lejos de significar que la materia es <> demuestra que es producto de una “laguna” en el sistema jurídico transnacional.
¿Sostenibilidad fuerte o débil?. Perspectivas de la protección jurídico- ambiental y ecosistémica de los humedales. El caso del Partido de Lobos, Provincia de Buenos Aires, Argentina
Authors: Minaverry Clara María
Published: November 2020

En el presente trabajo se propone, en primer lugar, realizar un relevamiento de la normativa aplicable al Partido de Lobos, en la Provincia de Buenos Aires, Argentina, para luego poder contrastarla con otra legislación vigente en otros países de América Latina. Luego de dicho análisis normativo, se determinará dentro de qué categoría doctrinaria se encuentra la misma: Sostentabilidad “super-fuerte”, “fuerte” o débil”. En segundo lugar, se analizarán los resultados de las encuestas realizadas a la población urbana del Partido de Lobos, y la información obtenida de entrevistas a informantes clave. Finalmente fue posible relevar que a menores niveles de educación y a mayor edad de los encuestados, se demuestra un bajo interés y preocupación vinculados con problemáticas ambientales. Además, el desarrollo normativo es incipiente, en tanto existen escasas políticas públicas ambientales vinculadas con la Laguna de Lobos, a pesar de que implica un importante aporte económico proveniente del turismo.

Based on these three characteristics, it indicates that most employees experience conflict in work-family, but it does not affect job satisfaction; (2) There are five characteristics of family-work conflicts but employees still apply professionalism. This indicates that there is no direct conflict but it can trigger stress due to family demands on religious holidays and public holidays; (3) Physical exhaustion can lead to conflict when faced with family demands regarding that role.
ON THE INTERPRETATION OF THE TERM "LEGAL REGULATION"
Authors: Юсупов Рахимьян , Султанов Тимур
Published: November 2020

The article examines approaches to the definition of the concept «legal regulation». It was found that this new term was defined by soviet scientists in the 1960s. However, some modern researchers demonstrate the freedom of speech and propose their own versions of definitions. They often include in the formulation the features of legal regulation that seem to them the most important. The analysis of the studied definitions made it possible to conclude that their semantic meaning may be different, but the essence of the studied phenomenon does not change from this. Regulation is understood as ordering. Legal regulation logically means ordering by means of law, which is characterized by: normativity, formal certainty, universality and compulsion. The complex of these features distinguishes law from other regulators of social relations, for example, religion or morality. Legal regulation was interpreted by scientists in the 1960s, taking into account these signs. The political, economic and social changes that took place in post-Soviet Russia did not affect on the essence of the phenomenon.

Bugüne kadar kablosuz iletişim teknolojileri sabit spektrum atama prensibi ile hazırlanmış ve kullanılmıştır. Sabit spektrum atama prensibine göre belirli frekans bandı sadece birincil (lisanslı) kullanıcılara ayrılmakta, birincil kullanıcılar tarafından kullanılmıyor olsa dahi ikincil (lisanssız) kullanıcıya tahsis edilememektedir. Bu ilke, frekans spektrumunun verimsiz kullanılmasına neden olmaktadır. Günümüzde kablosuz iletişim teknolojilerinin devamlı gelişmesi ve yaygın kullanımıyla beraber, sınırlı olan frekans spektrumu yetersiz kalmaktadır. Bilişsel Radyo Teknolojisi, dinamik spektrum erişim tekniğini kullanarak frekans spektrumun verimli kullanılmasını amaçlamaktadır.

CD46 and Oncologic Interactions: Friendly Fire against Cancer
Authors: Elvington Michelle , Liszewski M. Kathryn , Atkinson John P.
Published: November 2020

One of the most challenging aspects of cancer therapeutics is target selection. Recently, CD46 (membrane cofactor protein; MCP) has emerged as a key player in both malignant transformation as well as in cancer treatments. Normally a regulator of complement activation, CD46 is co-expressed as four predominant isoforms on almost all cell types. CD46 is highly overexpressed on a variety of human tumor cells. Clinical and experimental data support an association between increased CD46 expression and malignant transformation and metastasizing potential. Further, CD46 is a newly discovered driver of metabolic processes and plays a role in the intracellular complement system (complosome). CD46 is also known as a pathogen magnet due to its role as a receptor for numerous microbes, including several species of measles virus and adenoviruses. Strains of these two viruses have been exploited as vectors for the therapeutic development of oncolytic agents targeting CD46. In addition, monoclonal antibody-drug conjugates against CD46 also are being clinically evaluated. As a result, there are multiple early-phase clinical trials targeting CD46 to treat a variety of cancers. Here, we review CD46 relative to these oncologic connections.
Opportunist Coinfections by Nontuberculous Mycobacteria and Fungi in Immunocompromised Patients
Authors: Joao Ines , Bujdáková Helena , Jordao Luisa
Published: November 2020

Nontuberculous mycobacteria (NTM) and many fungal species (spp.) are commonly associated with opportunistic infections (OPIs) in immunocompromised individuals. Moreover, occurrence of concomitant infection by NTM (mainly spp. of Mycobacterium avium complex and Mycobacterium abscessus complex) and fungal spp. (mainly, Aspergillus fumigatus, Histoplasma capsulatum and Cryptococcus neoformans) is very challenging and is associated with poor patient prognosis. The most frequent clinical symptoms for coinfection and infection by single agents (fungi or NTM) are similar. For this reason, the accurate identification of the aetiological agent(s) is crucial to select the best treatment approach. Despite the significance of this topic it has not been sufficiently addressed in the literature. This review aims at summarizing case reports and studies on NTM and fungi coinfection during the last 20 years. In addition, it briefly characterizes OPIs and coinfection, describes key features of opportunistic pathogens (e.g., NTM and fungi) and human host predisposing conditions to OPIs onset and outcome. The review could interest a wide spectrum of audiences, including medical doctors and scientists, to improve awareness of these infections, leading to early identification in clinical settings and increasing research in the field. Improved diagnosis and availability of therapeutic options might contribute to improve the prognosis of patients’ survival.

Published: November 2020

In this study, the recovery of polyphenols from olive oil mill and winery waste was investigated. The performance of ultrasound assisted extraction (UAE), microwave assisted extraction (MAE), and pressurized liquid extraction (PLE) was assessed using ethanol–water mixtures, which are compatible with food, nutraceutical, and cosmetic applications. The extraction efficiency from olive pomace and lees samples was evaluated in terms of total polyphenol content (TPC), determined by high performance liquid chromatography (HPLC) and Folin–Ciocalteu assay. The effect of solvent composition, temperature, and time was analyzed by response surface methodology. Ethanol:water 50:50 (v/v) was found to be a suitable solvent mixture for both kinds of samples and all three extraction techniques. The performance of the extraction techniques was evaluated, under optimal experimental conditions, with a set of different representative samples of residues from olive oil and wine production. Overall, the best extraction efficiency for olive pomace residues was provided by MAE (ethanol:water 50:50 (v/v), 90 °C, 5 min), and for wine residues by PLE (ethanol:water 50:50 (v/v), 100 °C, 5 min, 1 cycle). However, the results provided by UAE (ethanol:water 50:50 (v/v), 30 min) were also suitable. Considering not only extraction performance, but also investment and operational costs, UAE is proposed for a future scaling up evaluation. Regarding olive pomace as a source for natural phenolic antioxidants, olive variety and climatic conditions should be taken into account, since both influence TPC in the extracts, while for winery residues, lees from red wines are more suitable than those from white wines.
Additive Manufacture of 3D Auxetic Structures by Laser Powder Bed Fusion—Design Influence on Manufacturing Accuracy and Mechanical Properties
Authors: Maran Sibi , Masters Iain G. , Gibbons Gregory J.
Published: November 2020

The mechanical response of steel auxetic structures manufactured using laser-powder bed fusion was explored. The level of control exerted by the key design parameters of vertical strut length (H), re-entrant strut length (L), strut thickness (t) and re-entrant angle (ϴ) on the mechanical response was examined through a design of experiment approach with ANOVA statistical analysis methods applied. The elastic modulus in directions normal to (Ex) and parallel to (Ey) the vertical strut was found to be primarily dependent upon t and L, respectively, whereas yield strength in both test directions (σx and σy) was strongly dependent on t and L. A large variation in modulus was found between the two test directions (Ex / Ey – 1.02 ± 0.07 GPa/ 4.4 ± 0.1 GPa), whereas, yield strength showed little anisotropy (σx / σy–45 ± 6 MPa/ 45 ± 9 MPa). Poisson’s ratio parallel to the vertical strut varied considerably with geometry but not in a direction normal to the vertical strut. Deformation mechanisms were found to be different of compression in the x and y directions, being a combination of stretching of the vertical strut; compression, bending and hinging of the re-entrant strut (x); and vertical strut compression and re-entrant strut stretching and bending (y).

Active myofascial trigger points (MTrPs) in masticatory muscles are associated with a reduced range of motion and muscle weakness within the stomatognathic system. However, it is hard to identify the most effective treatment technique for disorders associated with MTrPs. The objective of this study was to analyze the acute effect of the compression technique (CT) on active maximal mouth opening (MMO) and electromyographic activity of the masseter (MM) and temporalis anterior (TA) muscles in subjects with active myofascial trigger points in the MM muscles. The study group comprised 26 women (mean age 22 ± 2) with bilateral active myofascial trigger points (MTrPs) in the MM. The control group comprised 26 healthy women (mean age 22 ± 1) without the presence of MTrPs in the MM. Masticatory muscle activity was recorded in two conditions (during resting mandibular position and maximum voluntary clenching) before and after the application of the CT to the MTrPs in MM. After the CT application, a significant decrease in resting activity (3.09 μV vs. 2.37 μV, p = 0.006) and a significant increase in clenching activity (110.20 μV vs. 139.06 μV, p = 0.014) within the MM muscles were observed in the study group, which was not observed within TA muscles. Controls showed significantly higher active MMO values compared to the study group before CT (50.42 mm vs. 46.31 mm, p = 0.024). The differences between the study group after CT and controls, as well as among the study group before and after CT did not reach the assumed level of significance in terms of active MMO. The compression technique appears to be effective in the improvement of the active maximal mouth opening and gives significant acute effects on bioelectric masticatory muscle activity. Therefore, CT seems to be effective in MTrPs rehabilitation within the stomatognathic system.

Smart spring support is a kind of active damping device based on piezoelectric material. It can effectively suppress the vibration of a shaft system in an overly critical state by changing the stiffness and damping of the support. The support parameters have a significant impact on the vibration of the system. By studying the influence of the smart spring support parameters on the vibration characteristics of the transmission shaft system, the support parameters can be configured more reasonably so that the vibration of the transmission system can be reduced as much as possible. Based on the finite element method, this paper studies the influence of the stiffness, damping and mass of the smart spring support on the vibration characteristics of the three-support shafting. Firstly, the smart spring shafting test bed is built, and the vibration reduction performance test of the smart spring is carried out to verify the damping effect of the smart spring. Then, the shafting dynamic model is established by the finite element method, and the inherent characteristics of the system are analyzed. Finally, the influence of the stiffness, damping, mass and other parameters of the smart spring support on the dynamic response of the system is studied. The results show that increasing the stiffness of the smart spring support can effectively reduce the vibration amplitude of the system. The damping of the smart spring support has no obvious effect on the vibration of the shafting. The smaller the mass of the smart spring support, the more favorable the system is.

Gastric cancer (GC) still represents a relevant health problem in the world for both incidence and mortality rates. Many studies underlined that natural products consumption could reduce GC risk, indicating flavonoids as responsible for the beneficial effects through the modulation of several biological processes, such as the inhibition of cancer antioxidant defense and induction of apoptosis. Since Feijoa sellowiana fruit is known to contain high amounts of flavonoids, among which is flavone, we evaluated the antiproliferative and proapoptotic effects of F. sellowiana acetonic extract on GC cell lines through MTS and Annexin-V FITC assays. Among three GC cell lines tested, SNU-1 results being sensitive to both the F. sellowiana acetonic extract and synthetic flavone, which was used as the reference treatment. Moreover, we evaluated their antioxidant effects, assessing the activity of the antioxidant enzymes supeoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) in polymorphonuclear cells. We found a significant increase of their activity after exposure to both F. sellowiana acetonic extract and flavone, supporting the idea that a diet that includes flavone-rich fruits could be of benefit for health. In addition to this antioxidant effect on normal cells, this study indicates, for the first time, an anticancer effect of F. sellowiana acetonic extract in GC cells.

Published: November 2020

In recent years, the number of machine learning applications (especially those involving deep learning) applied to predicting and discovering material properties has been increasing. This paper is based on using microstructure and carbon content to train machine learning models to predict the residual stress of carburized steel. First, a semantic segmentation model of the material organization structure (SegModel-MOS) was constructed based on the AlexNet network and initially trained on the PASCAL VOC2012 dataset. Then, the trained model was fine-tuned on an enhanced homemade dataset consisting of optical microstructures. The experimental results show that SegModel-MOS can distinguish acicular martensite, retained austenite, and lath martensite in microstructures. Finally, we used both support vector machine (SVM) and decision tree (DT) algorithms to establish a mapping relationship between the microstructure, carbon content, and residual stress to predict the residual stress of steel from its microstructure and carbon content. The experiments verified that the prediction model constructed in this study exhibits high accuracy and can directly predict residual stress without requiring any long-term measurements. Thus, the developed model provides a new approach to the study of residual stress in steel.
The Abbey of Saint-Denis and the Coronation of the King of France
Authors: Leschot Elodie
Published: November 2020

Addressing the coronation issue in France always comes down to talking about Reims, its archbishop, its cathedral, and its Holy Ampulla. If these elements are indeed constitutive of the consecration ceremony, they only became so from the 13th century onwards. Before that, Reims had difficulty asserting its alleged prerogative to welcome the consecration’s ceremony. The practice of “festival crowing”, practiced by monarchs to assert their authority, did not indeed help the metropolitan Reims to assert its monopoly. In this context, Saint-Denis sought recognition of his rights to host the royal ceremony. Saint-Denis has always been intimately connected to the monarchy and hosted Pepin the first consecration, Pepin the Short and his heirs, in 754. In the 12th century, Abbot Suger’s arrival at Abbey’s head marked a new impetus for the Abbey in this race for prestige. The Saint-Denis church’s reconstruction and its liturgical organization demonstrate the great project that the Abbey pursued through the hosting of the ceremony’s coronation of the Kings of France.
Potential Roles of O-GlcNAcylation in Primary Cilia- Mediated Energy Metabolism
Authors: Tian Jie L. , Gomeshtapeh Farzad Islami
Published: November 2020

The primary cilium, an antenna-like structure on most eukaryotic cells, functions in transducing extracellular signals into intracellular responses via the receptors and ion channels distributed along it membrane. Dysfunction of this organelle causes an array of human diseases, known as ciliopathies, that often feature obesity and diabetes; this indicates the primary cilia’s active role in energy metabolism, which it controls mainly through hypothalamic neurons, preadipocytes, and pancreatic β-cells. The nutrient sensor, O-GlcNAc, is widely involved in the regulation of energy homeostasis. Not only does O-GlcNAc regulate ciliary length, but it also modifies many components of cilia-mediated metabolic signaling pathways. Therefore, it is likely that O-GlcNAcylation (OGN) plays an important role in regulating energy homeostasis in primary cilia. Abnormal OGN, as seen in cases of obesity and diabetes, may play an important role in primary cilia dysfunction mediated by these pathologies.

Biodiesel offers an important alternative to fossil fuel. In this work, Eversa Transform 2.0 lipase was immobilized onto 3-aminopropyltriethoxysilane (APTES) modified silica clay (SC) by glutaraldehyde. The characteristics of the functionalized supports and the immobilized lipase were investigated by FTIR, TEM, BET, and XRD. The results show that the optimal conditions of lipase immobilization are as follows: 2% glutaraldehyde concentration, 15 mg/mL lipase concentration and incubating at 25 °C for 60 min. The immobilized lipase showed a high tolerance to temperature and pH variation in comparison to the free lipase. The immobilized lipase on SC was applied as a biocatalyst for the synthesis of biodiesel from methanol and canola oil. A biodiesel yield of 86% was obtained at a temperature of 45 °C via a three-step methanol addition. A conversion yield of 67% was maintained after reusing the immobilized lipase for five cycles. This work provides a strategy for the preparation of an efficient biocatalyst for the synthesis of biodiesel.

The effect of Pd doping on nano-Ni catalyst hydrogenation aptitude in sulcatone (6-methyl-5-hepten-2-one) hydrogenation was investigated. Obtained results demonstrated that the addition of non-catalytic amounts of Pd to the surface of parent Ni catalyst improves the activity to the extent that it surpassed the activity of 2.16 wt% Pd catalyst (model catalyst) at optimal reaction conditions in the flow hydrogenation of an unsaturated ketone. Pd doping improves hydrogen activation on the catalyst, which was found to be a rate-limiting step using kinetic isotopic measurements and theoretical calculations.

Ru-Sn/TiO2 is an effective catalyst for hydrogenation of aqueous acetic acid to ethanol. In this paper, a similar hydrogenation process was investigated in a flow-type rather than a batch-type reactor. The optimum temperature was 170 °C for the batch-type reactor because of gas production at higher temperatures; however, for the flow-type reactor, the ethanol yield increased with reaction temperature up to 280 °C and then decreased sharply above 300 °C, owing to an increase in the acetic acid recovery rate. The selectivity for ethanol formation was improved over the batch process, and an ethanol yield of 98 mol % was achieved for a 6.7 min reaction (cf. 12 h for batch) (liquid hourly space velocity: 1.23 h−1). Oxidation of ethanol to acetic acid (i.e., the reverse reaction) adversely affected the hydrogenation. On the basis of these results, hydrogenation mechanisms that include competing side reactions are discussed in relation to the reactor type. These results will help the development of more efficient catalytic procedures. This method was also effectively applied to hydrogenation of lactic acid to propane-1,2-diol.
