Electrochemical Characterization of Cellulose Acetate/Chitosan Membrane in
Presence and Absence of Nonionic Surfactant in Monovalent Electrolytic Solution
Authors: Nath Satya , Tiwari A.K. , Tiwari P.K.
Published: October 2021

The influence of surfactant on cellulose acetate/chitosan membrane has been investigated. A basic
approach to cellulose acetate/chitosan membrane is also mentioned. Nonionic surfactants are disrupted
the normal permeability of the characteristic membrane. Electrochemical characterization such as
conductance, flow, flux and permeability are measured in various concentrations of the electrolyte
and surfactants. Membrane potential is determined by the combination of the properties of ions of the
electrolyte, surfactant and membrane. The synthesized membrane was found to be cation selective
with measured membrane potential found to be negative in all cases. The value of membrane potential
was varying in different concentration of the electrolyte and surfactant. The Teorell Meyer and Sievers
(TMS) theoretical method was employed for calculating the Transport number, perm selectivity and
fixed charge density of the membrane by using the data of membrane potential across normal and
surfactant modified membrane with electrolytic solution of NaCl. The variation of fixed density and
perm selectivity also depends on the concentration of the electrolyte and surfactant (Tween 20 and
Tween 60).

Published: October 2021

This work is focused on the synthesis and characterization of versatile acrylate polymer of chalcone
based triazine for their antibacterial activity and cumulative drug release behaviour studies. The novel
acrylate monomer 4-(3-(4-((4-(4-(3-(4-((7-chloroquinolin-4-yl)amino)-phenyl)-3-oxoprop-1-en-1-
yl)phenoxy)-6-((4-nitrophenyl)amino)-1,3,5-triazin-2-yl)oxy)phenyl)-3-oxoprop-1-en-1-
yl)phenylacrylate (SCP) is from novel chalcone and acryloyl chloride. Homo and copolymers of SCP
were prepared using acrylic acid and hydroxyethyl acrylate. Physical characterization confirms the
formation of the above compounds. Prepared drug molecules possess chalcone moiety as well as
quinoline so it has the greater effect to inhibit the growth of the Gram-negative bacteria (15.63 ± 0.4
μg/mL) was confirmed by MIC method. The weight average molecular weight of the polymer is
10,000 g/mol. The polymer decomposes at 325 ºC. Drug releasing in vitro behaviour of the synthesized
drug is controlled by the nature of comonomer, pH and the temperature.
A Simple and Effective Bio-adsorbent Generated from the Stems of Momordica charantia
Plant for the Simultaneous Removal of Lead and Cadmium Ions from Wastewater
Authors: Vabanagiri Rajesh Babu , Ravindhranath Kunta , Pala Sneha Latha , Kebede Biftu Wondwosen
Published: October 2021

Sulphuric acid generated activated carbon from the stems of Momordica charantia (MCSAC) was
identified to adsorb lead(II) and cadmium(II) ions from water. Extraction conditions were optimized.
At pH: 6, both the ions can be simultaneous removed by 2.0 mg/L of MCSAC after an equilibration
period of 90 min at room temperate (30 ± 2 ºC). The sorption capacities were observed to be 21.0 mg/g
for Pb2+ and 18.9 mg/g for Cd2+. MCSAC was characterized by conventional methods and also by
surface morphology assessing techniques such as XRD, FTIR and FESEM. The sorption mechanism
was investigated by evaluating thermodynamic parameters and by adopting various kinetic and
isothermal models. High ΔH values of 29.399 KJ/mol for Pb2+ and 33.222 KJ/mol for Cd2, indicated
that the mechanism of sorption is ion exchange and /or complex formation between Pb2+/Cd2+ ions and
surface functional groups present in MCSAC. Further, high positive ΔS values imply the presence of
disorder at solid-liquid interface, favouring the metal ions to overcome the surface barrier and get
adsorbed. The negative ΔG values indicates the spontaneity of sorption process. Spent MCSAC can be
regenerated and reused for three cycles. The procedure developed using MCSAC as sorbent was
successfully applied to treat real effluents samples collected from several industrial effluents. The
novelty of the present investigation is that a simple biosorbent is developed for the effective simultaneous
removal of highly toxic Pb2+ and Cd2+ from contaminated water.
Isolation and Characterization of Antioxidant Active Compounds from the
Leaves and Flowers of Manilkara hexandra (Roxb.)
Authors: Annamalai T. , Prince A.A.M.
Published: October 2021

Fractionation and chromatographic purification of the crude methanol extract of air-dried leaves of
Manilkara hexandra (Roxb) yielded five compounds p-methoxy methyl cinnamate (1),
p-hydroxymethylcinnamate (2), 2,5-dihydroxybenzaldehyde (3), gallic acid methyl ester (4) and
quercetin-3-O-β-D-glucoside (isoquercitrin) (5), whereas air-dried flowers yield phenylethylpalmitate
(6). The structures of these compounds were confirmed using spectroscopic data, comparison with
literature data and co-TLC comparison with authentic samples. To the best of our knowledge compounds
1, 3, 5 and 6 were isolated for the first time from this plant. Constituents of the plant were known to be
active against Staphylococcus aureus and Staphylococcus epidermidis. Comparative antioxidant activity
of compounds along with the crude extract and fractions were assessed using four different assay
protocols. These compounds show moderate activity in the antioxidant assay systems. Present results
rationalize the usage of the leaves and flower paste as bathing aid as suggested in the folklore literature
to maintain a dynamic balance of skin microflora.

with α,β-unsaturated ketones, 3-(2-chlorophenyl)-1-(4-hydroxyphenyl)-2-propenone or
3-(3-chloro-phenyl)-1-phenyl-2-propenone in dry ethanol in acidic medium in quest for the synthesis
of 1,5-benzothiazepine compounds, which may have interesting biological activities. The precursors,
substituted α,β-unsaturated ketones were obtained by employing the Claisen-Schmidt reaction; and
the final products, obtained by Michael condensation, were characterized by analytical and spectral
data comprising IR, 1H NMR and mass spectral studies. Two different series, 2,3-dihydro and
2,5-dihydro series of the final compounds were obtained depending on the substituents present, as
indicated by the 1H NMR spectra. The newly synthesized compounds were studied for their antimicrobial
activities against Staphylococcus aureus, Escherichia coli and Candida albicans taking imipenem,
vancomycin and fluconazole as reference standards using Paper Disc method. Five of the compounds
tested showed good antifungal activity against Candida albicans at the concentration of 200 μg/disc.

Mixture of Limonene Oxides with Secondary Amine and Carbamate
Authors: El Hammoumi M.M. , Said L. Ait , El Bachiri A. , Khoukhi M.
Published: October 2021

A simple kinetic separation of (1:1) diastereomeric mixture of limonene oxides was used to purify
cis-and trans-diastereomers of (R)-(+)-limonene oxide. The epoxide ring of trans-isomer was selectively
opened by (R)-N-methyl-(α-methyl-benzyl)amine. This secondary nucleophilic amine left cis-limonene
oxide largely unreacted and was obtained up to 90% yield. In a diverse way, (R)-N-(α-methylbenzyl)
ethyl carbamate, selectively catalyze hydrolysis of cis-limonene oxide to 1,2-limonene diol
leaving trans-limonene oxide largely unreacted. The unreacted trans-limonene oxide was recovered
in up to 75% yield. HPLC and NMR analyses were used to demonstrate that the isolation of cis-and
trans-diastereomers of (R)-(+)-limonene oxide has shown that > 98% were pure. As a result, depending
on the realization of the secondary amine or carbamate in the presence of water, either cis-or
trans-limonene oxide may be obtained in high diastereomeric purity.

Nanomaterials of biological origin are very useful for drug delivery applications. The stability,
biodegradability and biocompatibility of pectin nanomaterials in the human body make them an effective
drug carrier. This review focus on different aspect of synthesis, drug encapsulation, drug release and
safety of pectin-based nanomaterials. The nanomaterials can be used for the delivery of different
hydrophilic and hydrophobic drugs to various organs. The release kinetics of drug loaded pectin-based
nanoparticles can be studied in vitro as well as in vivo. The pectin-based nanomaterials have good
pharmaco-kinetics and can ensure controlled drug delivery. However, the toxicity of pectin-based
nanomaterials to human body needs to be evaluated carefully before industrial scale application.

Esta investigación se adelantó con el propósito de interpretar las prácticas de gestión humana, consideradas universales, realizadas en las microempresas colombianas del sector hotelero. Para ello, se empleó el método cualitativo, con fundamento en los planteamientos básicos de la Grounded Theory (Teoría fundada o fundamentada). Las fases de recopilación, análisis e interpretación de la información se orientaron ideológicamente por el método PRODIN (Prospective Dialectic Interpersonal Method).Entre los hallazgos más relevantes se destacan: la identificación de dos tipos de dirigentes (los dirigentes-empleados y los dirigentes-propietarios); la vinculación del personal orientada por la referenciación, la recomendación y la informalidad; la capacitación intuitiva y centralizada en el dirigente;la remuneración influenciada por lazos de consanguinidad (empleados familiares y empleados-no-familiares), los contratos verbales y el turno como unidad de trabajo; la informalidad en la evaluación del desempeño;la permanencia asociada a elementos de bienestar que favorecen el clima organizacional y a la avanzada edad de algunos colaboradores así como a la carencia de cualificación laboral para desempeñarse en otras actividades productivas;y la inexistencia de un plan de carrera.Como conclusiones se señalan: la centralización de la administración del negocio en el dirigente, la influencia del vínculo familiar en la toma de decisiones organizacionales y el “estilo propio” del empresario que caracteriza las prácticas de gestión humana en estas organizaciones.
About the profile of companies and products preferred by millennial university students in Uruguay in the field of responsible consumption
Authors: Guerra Aragone Pablo Augusto
Published: October 2021

En este artículo analizamos los vínculos entre el consumo responsable y ciertas pautas de consumo orientadas por las dimensiones sociales, éticas y ambientales. En el marco de un proyecto de investigación sobre las pautas de consumo responsable en la población universitaria de la generación millennials en Uruguay, se exponen los resultados de una encuesta de opinión que arroja una importante predisposición hacia formatos de consumo que incorporan aspectos sociales y ambientales. La muestra corresponde a un muestreo no probabilístico de 328 casos. En concreto se analizarán cómo se comportan 14 variables según carrera universitaria y sexo. A manera de conclusión, observamos una opinión más responsable entre mujeres aunque no siempre adquiere relevancia estadística, y cuando ello ocurre, es con bajos valores. Lamentablemente, el tamaño de la muestra no nos permite sacar conclusiones sobre cómo afecta al comportamiento el tipo de carrera universitaria cursada. Aun así, parecería ser que los estudiantes de algunas carreras como las de ingenierías o Derecho manifiestan un comportamiento menos afectado por las dimensiones socioambientales y éticas, en tanto los estudiantes de carreras como Arquitectura y el conjunto de las Ciencias Sociales (no incluimos aquí las ciencias económicas) se comportan de manera más responsable. Si bien en el análisis comparado con otras investigaciones no queda claro si hay o no una asociación entre consumo responsable y nuevas generaciones, nuestro estudio expone que ciertas pautas de consumo responsable están afectando a la mayoría de los estudiantes universitarios millennials, aspecto que estaría confirmando una correlación entre niveles de escolaridad y consumo responsable.

Some characterization tests for an extrapolation chamber in CT standard beams in a specific chamber depth
Authors: Castro Maysa Costa
Published: October 2021

The use of Computed Tomography (CT) for diagnostic images has been growing due to technological advances of this equipment. Therefore, there is a concern regarding the dose received by the patients undergoing this procedure, and this procedure needs to be performed with the highest precision and accuracy possible.The radiation detector used for CT beams is a pencil-type ionization chamber. However, there is no primary standard system for this kind of radiation beam. In this work a homemade extrapolation chamber was used to establish a CT primary standard [1]. This detector was tested for low-energy radiation beams and showing results within the internationally acceptable limits [2].This work had the objective to study the response stability of an extrapolation chamber, as well as obtaining the energy dependence and the angular dependence in standard CT beams of the Calibration Laboratory of IPEN (LCI).
Concentration and distribution of oil in the reservoir mineral Dolomite studied by neutron tomography
Authors: Pugliesi Reynaldo , Pereira Marco Antônio Stanojev , Andrade Marcos Leandro Garcia
Published: October 2021

Neutron Tomography – NT is a non-destructive technique, ideal for imaging hydrogen-rich substances even when wrapped up by thick rock layers. In the present study, the NT was employed for investigating the oil concentration and distribution in the mineral Dolomite, a natural oil reservoir. Two types of Dolomite samples, one of which dry, and the second one in oil-saturated were prepared. The applied oil was EMCAplus® 070 usually employed in permeability experiments to reproduce conditions of natural oil reservoirs. Three small fragments of the dry sample and three of the oil sample were inspected by NT and the comparison between the obtained results enabled, to distinguish several regions in which the oil is stored, to indicate that the oil is dispersed throughout the volume of the samples, and to quantify the storage concentration. The obtained data for oil concentration, for the three fragments, were compared to each other and to the one obtained by the conventional gravimetric technique, and they agreed within their uncertainties, demonstrating the viability of the NT technique to inspect, either in a qualitative as in a quantitative level, this oil reservoir mineral.
Analysis and comparison of computer programs to analyze the irradiation performance of Uranium Molybdenum monolithic fuel plates and Uranium dioxide cylindrical fuel rods in power reactors.
Authors: Silva André Luiz Candido da , Silva Antonio Teixeira e
Published: October 2021

The aim of this work is to present a comparative analysis in terms of the irradiation performance of cylindrical uranium dioxide fuel rods and monolithic uranium molybdenum fuel plates in pressurized light water reactors.To analyze the irradiation performance of monolithic uranium molybdenum fuel plates when subjected to steady state operating conditions in light water pressurized reactors, the computer program PADPLAC-UMo was used, which performs thermal and mechanical analysis of the fuel taking into account the physical , chemicals and irradiation effects to which this fuel is subjected. For the analysis of the uranium dioxide fuel rods, the code FRAPCON was used, which is an analytical tool that verifies the irradiation performance of fuel rods of pressurized light water reactor, when the power variations and the boundary conditions are slow enough for the term permanent regime to be applied. The analysis for a small nuclear power reactor, despite the higher power density applied to the fuel plate in relation to the fuel rod, showed that the fuel plates have lower temperatures and lower fission gas releases throughout the analyzed power history, allowing the use of a more compact reactor core without exceeding the design limits imposed on nuclear fuel.
Archaeometry and Archaeology: preliminary studies of the ceramics from archaeological sites of the upper Madeira river/Rondônia - Brazil.
Authors: Costa Angislaine Freitas , Munita Casimiro Sepúlveda , Zuse Silvana , Kipnis Renato
Published: October 2021

In southwest Amazonia, in the region of the Upper Madeira River, Rondônia, archaeological research has shown that communities with diverse cultures co-existed in the pre-colonial past (ca. 1,000 BP). Archaeological sites from this period located on river banks and islands consist of large extensions of ceramic deposits which reflect different daily activities and social positions that existed within these groups. The complexity of these societies is attested to by the diversity of both ceramic forms and iconography. In this work, 140 ceramic fragments from eight archaeological sites were studied by means of instrumental neutron activation analysis (INAA) to determine Na, K, La, Sm, Yb, Lu, U, Sc, Cr, Fe, Co, Zn, Rb, Cs, Ce, Eu, Hf, Ta and Th mass fractions, with the purpose of classifying and ordering artifacts which are related to one another in their chemical compositions. The analytical method used is adequate for this type of study because it is a semi-destructive technique with high sensitivity and precision that can determine chemical elements in trace and ultra-trace levels, essential for studying small variations in elemental concentrations. Multivariate statistical analyses were used to evaluate the dataset. Initially the mass fractions were normalized to compensate for the large difference in magnitude among elements determined in percentage and in trace level. Subsequently, the mass fraction data were interpreted through cluster analysis, discriminant analysis and a log-log scatterplot. The results show the existence of four compositional groups, indicating different clay sources.

Міжнародні експерти зі зміни клімату в 2018 році зазначали, що при поточних темпах викидів СО2 в найближчі 10 років у світі температура підвищиться на1,5 °C, що призведе до танення льодовиків і підвищення рівня моря.Проблематика. Оксид карбону може бути використано для отримання значної кількості органічних сполук, утворення яких залежить від методу його переробки. До останніх належать такі методи як біологічні, термічна конверсія, фотохімічні, плазмові. Більшість з них потребують застосування каталізаторів. Одним із плазмових методів є електронно-каталітичний метод з використанням бар’єрного розряду.Мета. Визначення основних фізико-хімічних закономірностей процесу електронно-каталітичного перетворення СО2 в органічні сполуки, а саме в метанол та формальдегід, з використанням двох розрядників — джерела низькотемпературної плазми.Матеріали й методи.

Bare Root Infinitives in German
Authors: Rapp Irene , Riecker Susanne , Brockmann Saskia , Fortmann Christian , Bozenhard Jonas
Published: October 2021

The aim of this paper is to show how linguistic and literary studies can benefit from a joint work about linguistic structures in poetry. Firstly, the analysis of poetry has an important impact on linguistic theory as it leads our attention to specific structures and meanings that so far have not been considered. Secondly, a close linguistic analysis can reveal hitherto overlooked facets of meaning which have a great significance for the overall interpretation of a poem.
We focus on Bare Root Infinitives (BRIs) in German. As they lack the features for tense, mood, person and number, they are more flexible in meaning than finite forms. When looking at poetry, besides the well-known deontic and bouleticmeanings (cf. Reis 1995, 2003; Gärtner 2014) a third meaning that we call reactive meaning stands out. Remarkably, this reactive meaning can also be found in everyday language. Its specific semantic properties show that a semantic analysis of BRIs in the style of Kaufmann (2012) is adequate: modality, but not non-referentiality, is a “hard-wired” semantic property of BRIs. The specific case study of the poem ‘muster fixieren’ (‘fixating patterns’) by Nico Bleutge reveals how the restricted context of the poem interacts with the different interpretations of BRIs to arrive at a complex text interpretation.
Keywords: bare root infinitives, semantic-pragmatic interface, poetry, modality, pragmatic enrichment, semantics
Civil law and the role of the State
Authors: Harmathy Attila
Published: October 2021

The profound changes in both everyday life and the legal system over the last hundred years have transformed civil law as well. While the notion that civil law concerns relationships of private persons still prevails, the traditional public law–civil law division now seems questionable. This paper points out some of the key changes in civil law within the framework of the transformation of the legal system as a whole, and seeks to outline a different approach that may help better to understand the present situation.

A field experiment was conducted at AICRP on water management, Belavatagi, UAS, Dharwad, during 2013-14 on soil deficient in available nutrients to study the effect of irrigation and nutrient management approaches on maximizing productivity, and economics of maize (Zea mays L.)-chickpea (Cicer arietinum L.) cropping sequence under command area. The results revealed that, crop receiving irrigation at 0.8 IW/CPE recorded significantly higher maize grain yield (70.80 q/ha) with higher gross return (Rs.88,924 ha-1), net return (Rs. 65,804 ha-1) and B-C ratio (3.84) compared to other treatment. However, in pooled analysis, the yields were on par with different irrigation levels. Among different level of boron applied to soil or through foliar application from 2 to 6 kg granubour/ha increased the yield over no boron application. But significant results obtained at 6 kg granubour/ha application and foliar application of 0.5 % of FeSO4 and 0.5 % of ZnSO4 with borax @ 0.1 % at 30 and 45 DAS. The interaction effects between irrigation and boron levels showed that, irrigating the crop at 0.8 IW/CPE along with foliar application of 0.5 % FeSO4 and 0.5 % ZnSO4 with borax @ 0.1 % at 30 and 45 DAS recorded higher yield, higher gross returns, net returns, B-C ratio and WUE over the treatments. But, it was on par with all the treatments that receive the boron either through soil or foliar application. During Rabi season chickpea was grown as succeeding crop after maize in Kharif the results showed that, irrigating at 0.8 IW/CPE with Granubor (boron) @ 6 kg/ha followed by growing of chickpea with 0.6 IW/CPE recorded significantly yield and economics.
Effect of media concentration and growth hormones on shoot regeneration and in vitro rooting of sugarcane varieties (Saccharum spp. )
Authors: Sheelamary S. , Nandhini L. Vidhya
Published: October 2021

The protocol for plantlet induction and regeneration through in vitro culture was standardized for the sugarcane variety Co 06022 with Co 86032. Genotype specific media combinations for establishment and rooting efficiency was identified and standardized. Multiple shoot regeneration was observed at different frequencies, using different concentration and growth regulator combination. In vitro propagation of Saccharum offers opportunities for increasing plant material for cultivation. Apical meristems were cultured on modified MS medium containing different concentrations of auxins. In Co 06022, the most effective concentration was combination of ½ MS medium supplemented with IBA (2.0 mg/l) which induced an average of 3.00±0.14 number of shoots per microshoot with 10.77±0.42 cm shoot length. Among the auxins used, NAA showed better response than IBA for profuse rooting in Co 06022. The number of roots formed was maximum (14.80±0.09) in MS with NAA (2mg/l) which had taken 10 days for root initiation with the root length of 6.45±0.07 cm. However, in Co 86032, the best performance was observed on ½ MS medium supplemented with IBA (2.0 mg/l) with more number of shoots (2.00 ± 0.19) and average shoot length of 12.30± 0.44 cm. Best rooting was observed in ½ MS medium supplemented with NAA (2.0 mg/l) and maximum number of roots were 11.60±0.12 which has taken 8 days for initiation of root primordia with average root length of 1.16±0.12 cm. Thus, it can be deduced that this protocol can be used successfully for in vitro rooting and acclimatization of these genotypes.

Resumo Este artigo, de natureza teórico-metodológica, discute a relação entre prosódia e compreensão leitora a partir de dois enfoques. O primeiro trata dos diferentes recursos metodológicos adotados na investigação dessa complexa relação, e o segundo versa sobre a controvérsia existente quanto à maneira como se configura essa relação. Reflexões como essas permitem aprofundar o conhecimento acerca das características dos diferentes recursos metodológicos adotados na investigação de dado fenômeno, assim como contribuem para esclarecer controvérsias em determinado campo do conhecimento, como é o caso da relação entre prosódia e compreensão leitora, tema ainda aberto a muitas interpretações. As discussões tomam por base pesquisas realizadas com crianças matriculadas no ensino fundamental.
Concentração fundiária, quilombos e quilombolas: faces de uma abolição inacabada
Authors: Silva Alcione Ferreira
Published: October 2021

Resumo Neste artigo, examinamos a interconexão entre a colonização na América Portuguesa, a concentração fundiária e o processo de escravização e libertação da população negra no Brasil, evidenciando o impacto dessa interconexão sobre o acesso à terra para quilombos e quilombolas. Por objetivo, buscamos compreender a importância dos territórios tradicionalmente ocupados, como meio de fortalecimento da experiência de liberdade nas comunidades quilombolas. Para tanto, recorremos à pesquisa bibliográfica e documental a partir de documentos orais, com abordagem qualitativa e uso da metodologia da história oral, sob a perspectiva de análise materialista, histórica e dialética. Concluímos que, em face do processo socio-histórico de base colonial-escravocrata, as dificuldades estruturais de acesso à titulação dos territórios quilombolas atuam como mecanismos que perpetuam sequelas advindas do período da escravidão, nas relações de trabalho e vida dos(as) quilombolas brasileiros, impondo restrições à experiência de liberdade, mesmo após a Abolição.

Published: October 2021

Resumen El objetivo del estudio consiste en analizar desde la perspectiva histórico-crítica las prácticas políticas — ya sean politizadas o despolitizadas — de trabajadoras sociales1 del Área Metropolitana de Monterrey (AMM), Nuevo León, México, que laboran tanto en áreas de intervención tradicionales como emergentes. Para la investigación se seleccionaron 9 instituciones y 11 trabajadoras sociales; se aplicó una entrevista a profundidad, un cuestionario sobre datos personales y de formación profesional, una guía de observación y un diario de campo. Los resultados arrojaron que, si bien, la práctica del trabajo social tiene como ideario ético-político contribuir al bienestar social; ésta se transforma con las instituciones, las políticas sociales, el modelo de producción y la cultura, y que, las participantes y los sujetos de intervención comparten una desprotección social que resulta clave para la despolitización de ambos.

RESUMO A representatividade da amostragem é fundamental para embasar a tomada de decisão, uma vez que a heterogeneidade da matriz é o principal fator para incerteza dos dados nos estudos de gerenciamento de áreas contaminadas. Neste estudo, coletaram-se 112 amostras de solo superficial em malha quadrada de 1 x 1 m, em uma área 15 x 6 m, no campus regional de Resende da Universidade do Estado do Rio de Janeiro. Anteriormente, no terreno funcionaram empresas de produção de filmes radiográficos e purificação de prata metálica. As amostras de solo foram analisadas por pXRF, método de screening para metais. Com base nos dados levantados, calculou-se, por meio de métodos estatísticos, a quantidade de amostras que permitiriam uma caracterização representativa da área, considerando um erro relativo de 20% para dois intervalos de confiança: 95 e 80%. As análises indicaram concentrações superiores aos valores de referência para os parâmetros prata, mercúrio, chumbo, selênio e zinco. Os resultados de mercúrio possivelmente referem-se a ruído espectral, não estando relacionados ao histórico de uso e ocupação. Os coeficientes de variação das concentrações dos elementos analisados variaram de 132 a 225%. Considerando uma distribuição lognormal, calcularam-se 76 amostras para o maior intervalo de confiança e 53 para o menor. Isso seria o equivalente a transectos com espaçamentos de 1,47 e 2,11 m. Os resultados ratificam a necessidade de investigações de alta resolução nas áreas fonte, conforme recomendado pela Decisão de Diretoria da Companhia Ambiental do Estado de São Paulo nº 038/2017/C (DD-038).

Published: October 2021

Aim: Platelets play an important role in the pathogenesis of thrombosis and atherosclerosis. Platelet Large Cell Ratio (P-LCR), a routine hemogram parameter, is the largest fraction of platelets that are more closely related to thrombotic events. In this study, for the first time in the literature, P-LCR levels in ischemic and hemorrhagic stroke patients were compared with the levels in transient ischemic attack (TIA) group.
Method: Retrospectively, hospital records between January 2016 and 2019, were searched by ICD-10 codes, and patients aged between 18-70 years who were diagnosed as ischemic stroke, hemorrhagic stroke and transient ischemic attack were included. The P-LCR test results in the first hemogram test of the patients taken at the time of admission to the hospital were included and compared.
Results: Of the 4511 patients, 92.6% (n=4177) were diagnosed with ischemic stroke, 6% (n=271) with hemorrhagic stroke, and 1.4% (n=63) of patients with TIA. The P-LCR levels of the ischemic and hemorrhagic stroke patients were found to be significantly higher than the TIA group (p=0.027; p=0.044, respectively). The Area Under the Curve (AUC) values for ischemic, hemorrhagic and total stroke versus TIA patients were 0.581, 0.568, and 0.580; respectively. The cut-off value of P-LCR was 26.65 ng/L between the ischemic stroke and TIA.
Conclusion: The increase in P-LCR levels can be used to distinguish ischemic and hemorrhagic stroke from TIA.

This protocol was designed to activate the lymphocytes T of a population of peripheral blood mononuclear cells (PBMCs), simulating their physiological response to antigen/MHC complex acting on T Cell Receptors-TCR , in order to test their functional responses including cell proliferation and cytokine production. The co-stimulation protocol include: i)anti-CD3 antibody a polyclonal activator specific for invariant framework epitopes on TCR complex (in particular, we use UCHT1 clone an anti-human CD3 antibody that recognizes the ε-chain of CD3 which is used for immobilized option of activation) (http://static.bdbiosciences.com/documents/BD_Tcell_Human_CD3_Activation_Protocol.pdf) ii) anti-CD28 antibody used to cooperate with TCR signals promoting activation of T cells The procedure has been reproduced following the indications contained in the protocol of "EBiooscience" (https://tools.thermofisher.com/content/sfs/manuals/t-cell-activation-in-vitro.pdf). Pilot experiments on PBMC were carried out to determine the best concentrations of anti-CD3 and anti-CD28 to induce optimal proliferation of PBMC and production of cytokines TNF-α and IFN-γ. We found a dose dependent correlation between immobilized anti-CD3 and cells functional responses. The selected amount was 2 µg/mL for both anti-CD3 and anti-CD28 that was the concentration below the maximum response which allows also to test possible modulations by therapeutic agents.

El odio hacia la mujer como móvil de la tragedia en Orestes de Eurípides
Authors: Perczyk Cecilia , Lombardi Gabriel
Published: October 2021

En la tragedia Orestes de Eurípides se representan los sucesos acontecidos en la ciudad de Argos luego del asesinato de Clitemnestra. El protagonista de la obra es el matricida Orestes, a quien se lo muestra sumamente excitado en la planificación de un nuevo crimen, el de Helena y su hija Hermíone. En el presente trabajo nos proponemos analizar el odio a la mujer como el móvil de la trama desde la teoría psicoanalítica de orientación lacaniana. El desprecio se constituye como un antecedente de la acción trágica al trasladarse de Clitemnestra hacia Helena, figura emblemática de la mitología griega por ser considerada la mujer más hermosa.
REINFORCEMENT UNDER LOAD OF DEFORMED COMPRESSED STEEL RAIL TRUSS
Authors: RODIONOV Igor K. , SAFRONOV Evgeniy G.
Published: October 2021

The results of the survey of steel trusses covering six industrial buildings are presented. In particular, the presence of various forms of defects of compressed rods was revealed: general bends in the plane and out of the plane of the truss, local perishes of the shelves - grinding and grinding. The necessity of strengthening the rods for further operation of the structures is determined. The proposed technical solutions for strengthening deformed rods are presented. When developing technical solutions, we tried to achieve, if possible, compensation for the damaged part of the cross-section (for locally damaged rods) and bringing the axis of the repaired rod to the design position (for rods with common bends). To confi rm the eff ectiveness of the proposed solutions, experimental studies were conducted. A brief analysis of the results is given.
