EM DEFESA DE UM DOGMA - GRICE E STRAWSON
Authors: Moreira Jorge
Published: June 2021

O presente texto foi publicado pela primeira vez em 1956, na revista The Philosophical Review, que apresenta uma discussão muito relevante para a filosofia contemporânea no século XX, a saber, a discussão acerca da crítica que Quine realiza contra os dogmas do empirismo. No artigo intitulado Two Dogmas of Empiricism, publicado no livro From a Logical Point of View, Quine ataca a distinção clássica entre enunciados analíticos e enunciados sintéticos. Grice e Strawson pretendem, no presente artigo, argumentar contrariamente à crítica feita por Quine, pois consideram que o autor exige demasiadamente o estabelecimento de critérios que suportem a afirmação da distinção mencionada. Por fim, o artigo dos autores pretende mostrar como o uso estabelecido da distinção é aceitável, uma vez que ela auxilia na resolução de algumas demarcações filosóficas. A presente tradução foi feita a partir do texto original, publicado em 1956.O presente texto foi publicado pela primeira vez em 1956, na revista The Philosophical Review, que apresenta uma discussão muito relevante para a filosofia contemporânea no século XX, a saber, a discussão acerca da crítica que Quine realiza contra os dogmas do empirismo.            No artigo intitulado Two Dogmas of Empiricism, publicado no livro From a Logical Point of View, Quine ataca a distinção clássica entre enunciados analíticos e enunciados sintéticos.            Grice e Strawson pretendem, no presente artigo, argumentar contrariamente à crítica feita por Quine, pois consideram que o autor exige demasiadamente o estabelecimento de critérios que suportem a afirmação da distinção mencionada.            Por fim, o artigo dos autores pretende mostrar como o uso estabelecido da distinção é aceitável, uma vez que ela auxilia na resolução de algumas demarcações filosóficas.            A presente tradução foi feita a partir do texto original, publicado em 1956.
A MORAL DO RISO EM BERGSON
Authors: Monteiro Geovana da Paz
Published: June 2021

O artigo aborda elementos para a compreensão de uma moral social no pensamento do filósofo francês Henri Bergson (1859-1941), a partir da obra de 1900, O riso, em diálogo com algumas idéias apresentadas em seu último livro, As duas fontes da moral e da religião. Em auxílio à nossa interpretação, faremos o cotejo com alguns textos de Sigmund Freud referentes à cultura e o comportamento humano em sociedade em fina sintonia com as ideias de Bergson. Embora O riso se pretenda um ensaio acerca da comicidade, o conteúdo da obra extrapola o campo de um mero estudo acerca do cômico nos entregando uma profunda reflexão estética sobre o valor da arte, além de uma crítica implícita à ciência através do confronto com outras teorias clássicas do riso. Todavia, o que nos interessa no momento é o destaque insistente dado por Bergson à função social que o ato de rir comporta. O riso seria uma espécie de ferramenta de ajuste dos comportamentos sociais. Suspeitamos, enfim, que haja naquela obra elementos para se pensar uma sociologia bergsoniana em estado embrionário, cujo desenvolvimento mais robusto só veremos nascer 32 anos mais tarde com a publicação d’As duas fontes.Palavras chave: Riso; Moral; Sociedade; Bergson; Freud.

EUROPA EN LA HISTORIA UNIVERSAL: UNA LECTURA DECOLONIAL DESDE LA FILOSOFÍA DE LA LIBERACIÓN
Authors: Narbona Isabel Guerra
Published: June 2021

Este trabajo es una crítica a la subjetividad moderna europea, que, a partir del siglo XVIII, ha impuesto al mundo una pretendida superioridad. Desde el diálogo con la Filosofía de la Liberación, podremos deconstruir ese mito de la Modernidad, y situar correctamente a Europa en la Historia Universal para mostrar su verdadero rostro. Como europeos necesitamos partir de un nuevo discurso, reconociendo públicamente el lugar que hemos ocupado en la Historia Universal. Solo a través de este reconocimiento de lo que somos podremos abrirnos a una nueva subjetividad más allá de la Voluntad de Poder, que ha sembrado tanto sufrimiento en la periferia.
DA CONSCIÊNCIA NACIONAL A AMÉRICA PROFUNDA: UM COTEJO ENTRE DIEGO PRÓ E RODOLFO KUSCH À LUZ DO PENSAMENTO DE E. DUSSEL
Authors: Santos Luciano Costa
Published: June 2021

No artigo a seguir, apresentaremos um escorço dos textos de Diego F. Pró e Rodolfo Kusch, publicados no livro-manifesto coletivo Hacia una Filosofía de la Liberación Latinoamericana, de 1973, que promoveu o lançamento mundial da Filosofia da Libertação. O cotejo desses textos terá como perspectiva norteadora o pensamento de E. Dussel – um dos mais proeminentes remanescentes da Filosofia da Libertação – e permite a apreciação de dois modos emblemáticos de considerar as questões estratégicas da nacionalidade e do povo, a partir da América Latina assumida como lugar hermenêutico e em chave de libertação decolonial.
ECOLOGÍA Y ÉTICA DE LA LIBERACIÓN: UN DIÁLOGO DECISIVO PARA UNA ARQUITECTÓNICA DEFINITIVA
Authors: Fabiani Enrique Téllez
Published: June 2021

El diálogo sistemático que Dussel sostuvo con Apel (1989-1995) es uno de los momentos más importantes en la historia de la filosofía latinoamericana; no solo porque a nivel regional sitúa el pensamiento formulado desde el subcontinente como propio, original e innovador; sino, define con toda precisión una crítica a las categorías filosóficas más importantes que quedaron plasmadas en una “arquitectónica”. Ésta trata de un orden metódico a través del cual debe ser discernida la realidad, con pretensión de universalidad y desde la criticidad que proveen las víctimas, como masas excluidas del planeta. En la primera parte, ponemos el acento en definir al interlocutor adecuado: el escéptico y el cínico, en la postura propia de las dos escuelas. En la segunda parte, resaltamos las limitaciones de la parte formal en detrimento de lo material. En la tercera y cuarta parte, ponemos énfasis en la verdad y la validez en la perspectiva ecológica. En la quinta, pasamos al “criterio universal de verdad”, como discernimiento mínimo para efectuar la crítica ecológica adecuada. En la sexta parte, retomamos los criterios pero tratando de definir lo que la filosofía de la liberación entiende por “víctima”. Finalmente, con formulaciones rápidas y sencillas, pero tratando de no ser reduccionistas, hablamos concretamente de la cuestión ecológica en concreto que deberá desarrollarse más ampliamente en un futuro.
LA JUSTICIA COMUNITARIA: UN ACERCAMIENTO DESDE LA FILOSOFÍA POLÍTICA DUSSELIANA

Published: June 2021

En este artículo pretendemos comprender la dimensión comunitaria de la justicia desde la Filosofía Política dusseliana. Partimos del reconocimiento de una especie de “momento oportuno” para que esta escuela de pensamiento, además de buscar la generación de una teoría crítica propositiva para “otro Estado posible”, también reconozca la potencia política de la arquitectónica, la crítica y el momento de la praxis constructiva que subyacen a la forma comunitaria en la política moderna.
NEM RORTY, NEM HABERMAS, NEM MARX: POR UMA FILOSOFIA DA PRÁXIS POIÉTICO-MATERIALISTA, NÃO LINGUOCÊNTRICA
Authors: Souza José Crisóstomo de
Published: June 2021

Nesse breve ensaio ofereço o esboço, condensado, de um ponto de vista prático-poiético, sensível, em filosofia, em diálogo crítico principalmente com os neo-pragmatismos linguocêntricos de Jürgen Habermas e Richard Rorty, com boa parte do pragmatismo clássico e, por fim, com o materialismo prático-dialético de Karl Marx. Faço isso com base nas noções, propostas por mim, de intencionalidade prático-sensível, de realidade e de nós próprios como atividade sensível, da ação humana como eminentemente poiética, também objetivação e apropriação, e, por conclusão, aponto para uma reconsideração do papel dos objetos nas nossa práticas, interações e mesmo auto-constituição, e faço um aceno a consequências políticas, democráticas, do referido ponto de vista.
DEBATENDO O PONTO DE VISTA PRÁTICO-POIÉTICO DE CRISÓSTOMO
Authors: Pereira Leonardo Jorge da Hora , Souza José Crisóstomo de
Published: June 2021

O debate começa pelo questionamento, por Leonardo Pereira, do possível caráter abstrato, demasiado geral,  da noção, central à posição prático-poiética de Crisóstomo de Souza,  da ação humana como poiésis e de nosso envolvimento básico com o mundo como um emaranhamento sensível prático criativo, de cujo caráter poderia resultar um déficit explicativo e também  normativo. E se desenvolve no questionamento da atribuição àquela ação de um caráter de produção de artefatos, e também da atribuição de um alegado caráter artefatual à própria realidade humana, que então não poderia ser propriamente apreendida como estrutura ou sistema, condicionamento e circunstância. Que assim tampouco poderia ser criticada - no marco do que parece ser um viés idealista romântico - por suas eventuais deformações nesse nível, em termos p. ex. de alienação, ocultação etc. Nesse quadro, a técnica tampouco seria suficientemente criticada por sua eventual dependência de uma nociva metafísica objetivista ou por sua determinação pelas imposições da ordem capitalista. Para Crisóstomo, que oferece em traços rápidos uma interpretação diferente para cada um desses casos, tais desafios resultam mais bem explicados na consideração do conjunto de seus textos mais recentes sobre seu ponto de vista prático. Que, admite Leonardo, poderia ter interesse como uma bem-vinda ruptura com posições tanto positivistas como linguocêntricas. Ou, em vez disso, ainda poderia permanecer presa a reducionismos próprios a outro paradigma produtivo, o de Marx. Mas, para Crisóstomo, suas noções de poiésis e intencionalidade sensível na verdade enriquecem uma noção mais material, efetiva, normativa, de autonomia humana, como suporte para uma noção transformativa mais promissora, crítica e inovadora, de democracia e de cidadania materiais, para além daqueles três paradigmas.
Ultra-broadband transmissive gradient metasurface based on the topologically coding optimization method

Published: June 2021

Metasurfaces have provided a novel way on modulating the wavefront of electromagnetic (EM) waves, where phase modulating is an important method to control EM waves. Normally, phase can be continuously modulated by changing the size of a meta-atom. For a broadband device, it is essential that phase changes linearly varying against frequency within a wide frequency interval, which is quite difficult to design, especially for the transmissive scheme. In this paper, we propose a 0-1 coding method by using genetic algorithm (GA) to realize broadband linear transmission phase and high transmission amplitude against frequency. To verify the method, a beam bending metasurface is designed based on array of six meta-atoms with step gap of 60°. Simulation and experimental results show that the metasurface deflector achieves perfect beam refraction from 8 to 12 GHz, which is consistent with theoretical calculations. Moreover, the working efficiency is kept at about 75%, with the variation of the frequency, which demonstrates the good stability of the metasurface. This method offers a new insight into the designing of broadband devices.
VMFNet: visual-microwave dual-modality real-time target detection model for detecting damage to curved radar absorbing materials

Published: June 2021

Damage to radar absorbing materials (RAMs) reduces the stealth capabilities and battlefield survivability of the equipment. Research on RAM damage detection technology is key to outfield equipment maintenance. In this paper, an intelligent RAM damage detection method based on visual and microwave modalities is proposed. A compressed sensing planar-scanning microwave imaging method based on a range migration algorithm (RMA) imaging operator and fast Gaussian gridding nonuniform fast Fourier transform (FGG-NUFFT) is proposed, achieving high imaging quality and speed. A dual-modality, curved RAM dataset (DCR dataset) is constructed, composed of visual images and microwave images showing two kinds of damage: round shedding and strip cracks. A new dual-modality target detection model, the visual-microwave fusion network (VMFNet), is designed to detect RAM damage. Its mean average precision (mAP) reaches 81.87%, and its inference speed reaches 35.91 fps. A visual network (VisNet) and microwave network (MicNet) are designed as the backbone of VMFNet for extracting the visual and microwave features of RAMs. A path aggregation network (PANet) unit is designed to fuse the multiscale features of the two modalities, resulting in good retention of shallow-level features and high detection accuracy. The head contains different receptive fields and outputs three scales of detection results, effectively detecting damage of different sizes.

Published: June 2021

Background and Aim: Mastitis, an inflammation of the mammary gland, is an ongoing problem in dairy herds. In this study, we determined the sensitivity of Staphylococcus aureus cultures of different biological origins to commercial bacteriophages and phages of S. aureus var. bovis which were isolated on dairy farms, to create a drug for the treatment of mastitis in cows.

Materials and Methods: We used cultures of S. aureus isolated from different habitats, and other types of staphylococci isolated on dairy farms. As antibacterial agents, the commercially available bacteriophages staphylococcal bacteriophage and Intestifag and field strains of phages Phage SAvB07, Phage SAvB08, Phage SAvB12, and Phage SAvB14 were used. Evaluation of their lytic properties was performed using the drip method.

Results: The drug Intestifag lysed cultures isolated from human habitats and archival strains of S. aureus No.209-P and S. aureus (ATCC 25923) in 91.8%–100% of cases. Staphylococcal bacteriophage killed 3.6 times fewer cultures of S. aureus isolated from humans than Intestifag and did not affect the growth of archival strains. Neither drug lysed cultures isolated from cows or cultures isolated from dairy products sold in agri-food markets. Phage SAvB14 lysed 92.7±8.3% of S. aureus isolated from the mammary glands of cows and 69.2±6.4% of cultures isolated from dairy products sold in agri-food markets. Phage SAvB12, Phage SAvB08, and Phage SAvB07 lysed 1.2-1.7 times fewer cultures isolated from the mammary glands of cows and 6-18 times fewer cultures isolated from dairy products, compared with Phage SAvB14. Phages of S. aureus var. bovis can infect staphylococcal species such as Staphylococcus epidermidis, Staphylococcus haemolyticus, Staphylococcus saprophyticus, and Staphylococcus xylosus. The widest range of hosts was found for Phage SAvB14, which indicates its polyvalence.

Conclusion: The biological origin of staphylococcal strains must be considered when developing effective phage therapy. Phage SAvB14 appears to be a good candidate for the development of a drug for the treatment of mastitis in cows.
Persistence of secondary hyperparathyroidism after parathyroidectomy in a patient with chronic kidney disease: a case report
Authors: Ilyicheva Elena A. , Bersenev Gleb A. , Bulgatov Dmitry A. , Makhutov Valeriy N.
Published: June 2021

This is a clinical case of surgical treatment of persistence of secondary hyperparathyroidism (SHPT) in a patient with chronic kidney disease after previous parathyroidectomy. Programmed hemodialysis started in 2014, and in 2016 SHPT was diagnosed. In November 2018, indications for surgical treatment were presented in one of the clinics. According to scintigraphy, an increase in the functional activity of all four parathyroid glands (PTG) was observed, according to ultrasound data, the localization of the right lower, left upper and lower PTG was established. Removal of 3x PTG was performed without revision of the thymus horns (11.2018), while in the postoperative period, an adequate decrease in parathyroid hormone was not observed. After additional examination, according to ultrasound, scintigraphy and computer tomography of the neck with intravenous enhancement, it was found that both lower PTGs are located in the upper horns of the thymus. In July 2020, a repeated surgical intervention was performed in the volume of the right lower and left lower parathyroidectomy with a positive intraoperative test. Remission of SHPT was achieved. At present, no consensus has been reached on the extent of surgery for SHPT, since no statistically significant differences were found in the incidence of persistence / recurrence of SHPT. A complete assessment of the results of preoperative imaging techniques is required when planning surgery. Intraoperative monitoring of parathyroid hormone is an effective technique for assessing the radicality of surgical treatment.

Published: June 2021

Introduction: The Lambert’s Outcomes Questionnaire (OQ-45) is a 45-item self-administered instrument used to measure clinical outcomes in psychotherapy. It measures functioning through three areas: symptoms distress, interpersonal relations and social role. The objective of this paper is to assess the reliability and the validity of its Spanish version. Method:A sample of 639 subjects, non-clinical and clinical, completed the instrument. Results: The psychometric evidences of the questionnaire showed an adequate internal consistency (.97 and .91) and acceptable convergent validity with the BDI, STAI, PSS and SF-12. The Confirmatory Factor Analyses suggested a bifactor structure. The cut-off points have been established for the subscales and total score (54.5), considering the clinical criterion, which means, prioritizing slightly the sensibility over the specificity. The RCI was 3.80 and Minimum Change Score 17.56. Conclusion: The OQ-45 showed acceptable psychometric properties, providing support for using this version of the questionnaire to assess Spanish’s functionality. Given these findings, this tool could help clinicians evaluate treatment efficacy and establish psychotherapy goals.

Anne in Swedish. How the Spirit of the Age and Production Terms Influence the Protagonist’s Character Traits in Swedish Translations and Adaptations of Anne of Green Gables

 L.M. Montgomery’s Anne of Green Gables (1908) has received much academic interest. Drawing on related research on the novel and its Swedish editions, my article investigates how the variation in the Swedish versions influences the characterization of Anne 1909–2018. My study acknowledges the feminist view within translation studies as expressed by Sherry Simon, and uses Norman Fairclough’s linguistic model for contextualization. The primary material consists of Montgomery’s original text, the translations and adaptations by Karin Jensen, Aslög Davidson, Margareta Sjögren-Olsson, and Christina Westman as well as correspondence between the publishing houses and translators. Further, I have interviewed Westman and corresponded with her publisher. The texts are analysed regarding omissions and additions. On a micro-level, all active verbs where Anne is the grammatical subject are analysed. My results show that all editions give prominence to Anne’s academic ambition. A major finding is that the 1941 and 1962 versions increase Anne’s ambition by using more active verbs and stronger expressions. Westman’s 2018 edition, however, is a subtle revision of the first Swedish translation, with the result that Anne’s ambition is diminished again. Despite girls and women having gained more freedom over the last 100 years, the latest edition thereby interrupts the tendency to stress Anne’s ambition. This is understood as a result of clashing discursive and social norms. On the other hand, the emphasis on Anne’s ambition in the 1941 and 1962 editions comes with a cost of religious, moral, intellectual, and emotional aspects, creating a one-dimensional Anne.

Preparation of composite soybean straw-based materials by LDHs modifying as a solid sorbent for removal of Pb(ii) from water samples
Authors: Zhang Fengrong , Zhang Binghan , Han Dandan , Wu Lishun , Hou Wanguo
Published: June 2021

In this study, the nanocomposites from biomass (soybean straw) and layered double hydroxides (LDHs), denoted as B/LDHs, were fabricated using the mechanical-hydrothermal method. The obtained B/LDHs nanocomposites were characterized by TEM, SEM, FT-IR, and N2 adsorption–desorption techniques. Adsorption of the heavy-metal ions Pb(ii) on the B/LDHs was determined at 25°C and pH 6.0 using a batch technique. The experimental results demonstrated that biomass contributed to the sorption process. The pseudo-second-order, Langmuir, and Freundlich models well fitted the sorption process, indicating chemisorption and monolayer adsorption were the main adsorption mechanisms. Meanwhile, it is found that there is an obvious effect of adsorbent concentration in the studied adsorption system. In comparison with soybean straw and Mg–Al LDHs, the B/LDHs nanocomposites exhibit significantly enhanced sorption capacities. It is evident from this study that the construction of B/LDHs nanocomposites is an effective strategy for improving the sorption capacity of LDHs, and the modified LDH-based adsorbent shows a good potential in the removal of heavy metals from water. More importantly, it solves the problem of a large number of agricultural waste disposals. And, it achieved the goal of a win-win situation.
Stroke hospitalization after misdiagnosis of “benign dizziness” is lower in specialty care than general practice: a population-based cohort analysis of missed stroke using SPADE methods
Authors: Chang Tzu-Pu , Bery Anand K. , Wang Zheyu , Sebestyen Krisztian , Ko Yu-Hung , Liberman Ava L. , Newman-Toker David E.
Published: June 2021

Objectives

Isolated dizziness is a challenging stroke presentation in the emergency department, but little is known about this problem in other clinical settings. We sought to compare stroke hospitalizations after treat-and-release clinic visits for purportedly “benign dizziness” between general and specialty care settings.

Methods

This was a population-based retrospective cohort study from a national database. We included clinic patients with a first incident treat-and-release visit diagnosis of non-specific dizziness/vertigo or a peripheral vestibular disorder (ICD-9-CM 780.4 or 386.x [not 386.2]). We compared general care (internal medicine, family medicine) vs. specialty care (neurology, otolaryngology) providers. We used propensity scores to control for baseline stroke risk differences unrelated to dizziness diagnosis. We measured excess (observed>expected) stroke hospitalizations in the first 30 d (i.e., missed strokes associated with an adverse event).

Results

We analyzed 144,355 patients discharged with “benign dizziness” (n=117,117 diagnosed in general care; n=27,238 in specialty care). After propensity score matching, patients in both groups were at higher risk of stroke in the first 30 d (rate difference per 10,000 treat-and-release visits for “benign dizziness” 24.9 [95% CI 18.6–31.2] in general care and 10.6 [95% CI 6.3–14.9] in specialty care). Short-term stroke risk was higher in general care than specialty care (relative risk, RR 2.2, 95% CI 1.5–3.2) while the long-term risk was not significantly different (RR 1.3, 95% CI 0.9–1.9), indicating higher misdiagnosis-related harms among dizzy patients who initially presented to generalists after adequate propensity matching.

Conclusions

Missed stroke-related harms in general care were roughly twice that in specialty care. Solutions are needed to address this care gap.
Development and experimental validation of reactor kinetic model for catalytic cracking of eugenol, a potential bio additive fuel blend
Authors: Mani Mythily , Thangavelu Thyagarajan , Perumal Santhana Krishnan , Kannan Shanthi
Published: June 2021

An integrated kinetic model representing catalytic cracking of eugenol in a fixed bed reactor is developed. Eugenol, a major component of clove oil can act as the most potential bio additive fuel for improving the diesel quality thereby reducing the exhaust emission of the engine. The proposed integrated model includes four lump kinetic model which is plugged with catalyst deactivation model. The reactor design parameters are also included in the integrated model. The effectiveness of the proposed integrated model is compared with the conventional kinetic models and the results are presented. The proposed integrated model is validated against the real time data obtained by conducting an experiment in a real time setup with MoS2(Ni2P) Al-SBA-15(10) as the catalyst. The advantages of the proposed integrated model are highlighted.

Authors: Greene Debbie A. , Doss Josie L.
Published: June 2021

Objectives

Examine the impact of TeamSTEPPS® training and simulation experiences on student knowledge and teamwork attitudes in a baccalaureate-nursing program.

Methods

This study used a quasi-experimental, pre-test, post-test design. The intervention included a workshop followed by 2 days of simulation experiences. Participants included a total of 46 nursing students. Instruments included the TeamSTEPPS learning benchmark and the Teamwork Attitudes Questionnaire (T-TAQ).

Results

Scores on the learning benchmark increased following the intervention. In addition, changes in subscores of teamwork strategies, leadership, situation monitoring, and mutual support on the T-TAQ indicate an improvement in student attitudes toward teamwork.

Conclusions

Incorporating TeamSTEPPS® strategies into undergraduate education can be effective in increasing student knowledge and improving attitudes toward interdisciplinary teamwork.
“We thought about it together and the solution came to our minds”: languaging linguistic problem-solving in multilingual Finnish classrooms
Authors: Repo Elisa , Kivimäki Riia , Kekki Niina , Alisaari Jenni
Published: June 2021

This study examines a learning experiment in which linguistic problem-solving tasks designed to increase students’ (aged 9–13) language awareness through collaborative dialogue were introduced in multilingual primary school classrooms in Finland. The aim was to analyse how the students (N = 126) reported what was happening during the linguistic problem-solving tasks, drawing on the method of languaging. Additionally, the study investigates how meaningful, relevant and novel the students with diverse backgrounds found the tasks. The data were collected via a survey. Students’ problem-solving reports were analysed via content analysis, with the Taxonomy of Cognitive Process applied. Statistical analysis was used to measure the experienced meaningfulness, relevance and novelty. The analysis resulted in an understanding of the multiple voices in which the students articulated their thinking regarding linguistic problem-solving. The study sheds light on how to develop language aware learning materials to engage all students, regardless of their backgrounds, in discussions on language.
Intermittent exposure to green and white light-at-night activates hepatic glycogenolytic and gluconeogenetic activities in male Wistar rats
Authors: Ige Abayomi O. , Adekanye Olubori S. , Adewoye Elsie O.
Published: June 2021

Objectives

Exposure to light-at-night (LAN) has been reported to impair blood glucose regulation. The liver modulates blood glucose through mechanisms influenced by several factors that include peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1α) and glucose-6-phosphatase (G6Pase). This study investigated the effect of intermittent exposure to green and white LAN on some hepatic glucose regulatory factors in male Wistar rats.

Methods

Animals were divided into three equal groups. Group I (control) was exposed to normal housing conditions. Groups II and III were each daily exposed to either green or white LAN for 2 h (7–9 pm) for 14 days. Body weight and blood glucose was monitored on days 0, 7, and 14. Thereafter, retro-orbital sinus blood was obtained after light thiopental anaesthesia and serum insulin was determined. Liver samples were also obtained and evaluated for glycogen, PGC-1α, and G6Pase activity. Insulin resistance was estimated using the HOMA-IR equation.

Results

Body weight and blood glucose on days 7 and 14 increased in groups II and III compared to control. Hepatic PGC-1α and G6Pase increased in group II (2.33 ± 0.31; 2.07 ± 0.22) and III (2.31 ± 0.20; 0.98 ± 0.23) compared to control (1.73 ± 0.21; 0.47 ± 0.11). Hepatic glycogen was 71.8 and 82.4% reduced in groups II and III compared to control. Insulin in group II increased (63.6%) whiles group III values reduced (27.3%) compared to control. Insulin resistance increased in group II (0.29 ± 0.09) compared to control (0.12 ± 0.03) and group III (0.11 ± 0.03), respectively.

Conclusions

Exposure to 2 h green and white LAN in the early dark phase increases hepatic glycogenolysis and gluconeogenetic activities resulting in increased blood glucose. In male Wistar rats, exposure to green but not white LAN may predispose to insulin resistance.

Objectives

Obesity is often the result of a high-calorie and unbalanced diet for a long time and can sometimes be associated with hyperphagia and eating disorders. Neurotensin (NT) is an anorexigenic peptide, which is secreted from the central nervous system and intestines, and increases intestinal fat absorption. In the literature, conflicting results regarding serum NT level in obesity and the relation of NT with metabolic parameters were reported. Besides, there is no data regarding the relation of NT with eating disorders or food preference in obese individuals. We aimed to evaluate the relation of serum NT level with metabolic parameters, hyperphagia, binge eating disorder (BED) and food preference in obese adolescents.

Methods

The study included 65 obese adolescents and 65 healthy controls. Anthropometric measurements, biochemical analyzes and body fat analyzes were performed in all cases. Hyperphagia score, presence of BED and three-day food intake records were also evaluated.

Results

NT level was significantly higher in obese adolescents than in controls and it was not associated with metabolic parameters, hyperphagia or food preference. In the obese group, NT level was not significantly different according to the presence of BED.

Conclusions

Serum NT level is high in obese adolescents; however, it is not associated with metabolic parameters, hyperphagia, BED or food preference.
Hereditary hypophosphatemic rickets and craniosynostosis

Background

Craniosynostosis is an underdiagnosed complication associated with hypophosphatemic rickets. The study aims to describe the clinical and auxological characteristic of children with hypophosphatemic rickets and craniosynostosis, describe the usual treatment, and compare the characteristics with those of children without craniosynostosis.

Methods and patients

An observational and retrospective cohort study was conducted. Clinical notes and cranial images were reviewed. Out of 96 children, only the 50 patients who had skull images were included.

Results

Out of 50 patients, 26 (15 males) had craniosynostosis (52%). No differences were observed in birth size, age, height, body proportions, alkaline phosphatase, serum phosphate, or percent tubular reabsorption of phosphate at first appointment among children with or without craniosynostosis. Among patients with craniosynostosis, dolichocephaly was prevalent. The sagittal suture was affected in all patients with craniosynostosis, with 19 of 26 children (73%) affected with isolated scaphocephaly. Pan-sutural craniosynostosis was present in 7 children (27%). None of the children had microcephaly, 7 of them presented macrocephaly and, in the remaining subjects, head circumference was normal. Five patients had undergone at least 1 cranial remodeling surgery. One patient with craniosynostosis was diagnosed with a Chiari I malformation. Molecular characterization of PHEX gene was performed in 14 cases.

Conclusions

Craniosynostosis is an underdiagnosed complication of hypophosphatemic rickets. Many patients with normal head size and growth may go undiagnosed, thus it is important to consider this association for early diagnosis and possible surgical treatment. A multidisciplinary approach is necessary for a correct long-term follow-up.
Why They Know Not What They Do: A Social Constructionist Approach to the Explanatory Problem of False Consciousness
Authors: Wilson Lee
Published: June 2021

False consciousness requires a general explanation for why, and how, oppressed individuals believe propositions against, as opposed to aligned with, their own well-being in virtue of their oppressed status. This involves four explanatory desiderata: belief acquisition, content prevalence, limitation, and systematicity. A social constructionist approach satisfies these by understanding the concept of false consciousness as regulating social research rather than as determining the exact mechanisms for all instances: the concept attunes us to a complex of mechanisms conducing oppressed individuals to mistake social understandings of themselves as natural self-understandings—the limits lie where these overlap, or are entirely absent.

For the comprehensive investigation of advanced high strength steel grades, like complex and dual phase steels, Atomic Force Microscopy (AFM) and Scanning Kelvin Probe Force Microscopy (SKPFM) have proven to be useful tools, especially for analysis of hydrogen permeability of the individual steel phases. However, for these studies a preparation route, exposing the microstructure of the steel, is necessary. Various sample preparation methods were examined, focusing on electropolishing and sputtering, and the selected route was optimized to guarantee reproducibility and stability of the prepared surface. Electropolishing was shown to be highly efficient to selectively reveal the individual steel phases without introducing strong topographical features disturbing the AFM measurements. A subsequent sputtering step was introduced to improve the stability and preservability of the surface up to several months. Finally, distinction of the steel phases via AFM/SKPFM, was complemented and compared with results from EBSD and XRD.
Removal of cadmium and lead from aqueous solutions using iron phosphate-modified pollen microspheres as adsorbents
Authors: Zhang Xiaoxing , Liu Hui , Yang Jin , Zhang Li , Cao Binxia , Liu Libo , Gong Weimin
Published: June 2021

Iron phosphate-modified pollen microspheres (pollen@FePO4) were prepared and applied as sorbents for the removal of heavy metals (Cd2+ and Pb2+) from the aqueous solution. Batch sorption studies were conducted to investigate the effects of solution pH, contact time, sorbent dosage, and metal concentration on the adsorption process. The sorption of Cd2+ and Pb2+ ions on pollen@FePO4 corresponds to the pseudo-second-order model and Langmuir isotherm, which is similar to the unmodified pollen. At pH 5.92, pollen@FePO4 offers maximum adsorption capacities of 4.623 and 61.35 mg·g−1 for Cd2+ and Pb2+, respectively. The faster sorption kinetics and higher adsorption capacities of Cd2+ and Pb2+ ions onto pollen@FePO4 than pollen indicates that it might be a promising material for the removal of heavy metal ions in aqueous solutions. The possible adsorption mechanism involves electrostatic and chemisorption for Cd2+ and mainly complexion for Pb2+.
Accuracy of the typicality approach using Chebyshev polynomials
Authors: Schlüter Henrik , Gayk Florian , Schmidt Heinz-Jürgen , Honecker Andreas , Schnack Jürgen
Published: June 2021

Trace estimators allow us to approximate thermodynamic equilibrium observables with astonishing accuracy. A prominent representative is the finite-temperature Lanczos method (FTLM) which relies on a Krylov space expansion of the exponential describing the Boltzmann weights. Here we report investigations of an alternative approach which employs Chebyshev polynomials. This method turns out to be also very accurate in general, but shows systematic inaccuracies at low temperatures that can be traced back to an improper behavior of the approximated density of states with and without smoothing kernel. Applications to archetypical quantum spin systems are discussed as examples.
Reliability-Based Design Optimization of Chemically Stabilized Coal Gangue
Authors: Ashfaq Mohammed , Moghal Arif Ali Baig , Munwar Basha B.
Published: June 2021

The coal gangue (CG) is a noncombustible waste mechanically separated from coal during the sorting or coal washing phase of mining. Because of the negative implications of unscientific disposal of CG, there is a need to utilize it in bulk civil engineering works. More precisely, the application of CG in earthworks facilitates its bulk application. The present study aims to evaluate the unconfined compressive strength (UCS) characteristics of lime- and gypsum-treated CG. The lime and gypsum dosages were varied from 2 to 6 % and 0.5 to 1.5 %, respectively. The influence of lime and gypsum addition on the UCS was evaluated for varying curing periods (CPs) of 7, 14, and 28 days. An exponential model is developed to evaluate UCS based on the experimental data using lime content, gypsum content, and CP. Further, attempts were made to estimate the optimum amounts of lime and gypsum content for satisfactory UCS performance of stabilized CG using target reliability-based design optimization (TRBDO). Furthermore, carbon footprint analysis (CFA) was performed to quantify the environmental benefits attainable by applying CG as subbase material in the pavement. The results showed that the maximum dry density increased from 1.74 to 1.84 g/cc for 4 % lime addition. The UCS of CG linearly increased with an increase in lime dosage, gypsum dosage, and CP. The highest increment of 1,050 % was attained for 1.5 % gypsum and 6 % lime addition. The CFA results indicate that CG’s procurement (embodied) emissions are substantially higher, with an 88 % share in overall emissions. From the reliability studies, it is noted that the TRBDO is helpful in predicting the optimum dosages of lime and gypsum for the satisfactory performance of pavements.
Subcutaneous radiofrequency: prospective pilot study on safety and efficacy in face chrono-ageing treatment
Authors: Fanelli Benedetta
Published: June 2021

Objective: to evaluate the efficacy, safety and tolerance of the face aging treatment using subcutaneous radiofrequency in patients with mild, moderate e severe ptosis of the middle face. Material and methods: prospective data from patients treated with subcutaneous radiofrequency. Patients underwent two treatment session carried out by the same surgeon. The principal efficacy criterion was the assessment of depth reduction of the naso-labial fold and malar prominence’s restoration after 3 and 6 months, the evaluation of the Global Aesthetic Improvement Scale by the patients and an outside procedure surgeon was the second criteria. Safety and tolerance were evaluated through observed side effects. Result: A total of 30 patients, 27 women and 3 men with a mean age of 53 years underwent subcutaneous radiofrequency procedure. Depth’s reduction of the naso-labial fold and malar prominence’s restoration was observed in the majority of all case, associated to the patient e medical satisfaction. Transitory adverse effects, commonly for cosmetic procedure e.g erythema, edema was not observed. One patient had post procedure hematoma. No serious adverse effects such as burning or scars were reported. Conclusion: This prospective pilot data confirmed that subcutaneous radiofrequency is a safe and effective in improvement in skin laxity. Patients’ satisfaction was high. Although this treatment cannot substitute surgical procedure, it might prolong the time to the first surgical facial lift. Further confirmation investigation should be performed.

The clothing is not worn only for protecting the human body, but it helps to obtain comfort during high level activities or in unfavorable environmental conditions. Heat generated by the working human body in hot climate or high physical activity, which must be dissipated to the environment. Similarly, in the cold environment, the body is going to be shielded from cold feeling. Thermophysiological clothing comfort related to warmth and moisture transport behaviour of clothing. Good clothing helps to maintain body temperature during various level of physical activities and surrounding environmental condition. Therefore, some improved functional properties are desirable in the clothing. For clothing comfort, thermophysiological comfort properties of fabrics which are related to heat and moisture transport properties play very vital role. These properties can be introduced in the clothing by using various fibrous material and modifying the structure of yarns, fabrics and garments.

Published: June 2021

Epithelioid leiomyomas of the vagina are extremely rare benign smooth muscle tumors. Leiomyomas are located in uterus in 70%; however, paravaginal leiomyomas are rare, which frequency is 0.1% in adults women. They can be asymptomatic, but if they are, may cause signs of compression, dyspareunia, urinary disorders,… The diagnosis is made by histologic and immunohistochemical examination, helped by imaging tests such as RMN and ultrasound. The first treatment option is the resection by enucleation. Search of information was carried out in the PubMed/Medline, Cochrane, SciELO databases and references from articles in journals and recent published texts. This is a case report of a 29-years-old female who is derived to Gynecologic Emergencies because of a Bartholinitis refractory to antibiotic treatment. The gynecological exploration reports a vaginal mass which extends to left paravaginal space. The biopsy of this mass suggests the diagnosis of leiomyoma. MRI study reports a 49mm mass in left ischiorectal space which seems to depend on puborectal muscle. The resection is made by enucleation, with a histopathological examination that confirms the diagnostic suspicion.
