Nurses represent the highest proportion of healthcare workers globally and have played a vital role during the COVID-19 pandemic. The pandemic has shed light on multiple vulnerabilities that have impacted the nursing workforce including critical levels of staffing shortages in Canada. A review sponsored by the Royal Society of Canada investigated the impact of the pandemic on the nursing workforce in Canada to inform planning and implementation of sustainable nursing workforce strategies. The review methods included a trend analysis of peer-reviewed articles, a jurisdictional scan of policies and strategies, analyses of published surveys and interviews of nurses in Canada, and a targeted case study from Nova Scotia and Saskatchewan. Findings from the review have identified longstanding and COVID-specific impacts, gaps, and opportunities to strengthen the nursing workforce. These findings were integrated with expert perspectives from national nursing leaders involved in guiding the review to arrive at recommendations and actions that are presented in this policy brief. The findings and recommendations from this policy brief are meant to inform a national and sustained focus on retention and recruitment efforts in Canada.
The charged Zipoy–Voorhees metric with astrophysical applications
Authors: Gurtug Ozay , Halilsoy Mustafa , Mangut Mert
Published: August 2022

Starting from an integral of the interaction region of colliding Einstein–Maxwell waves and by applying a coordinate transformation, we obtain the charged version of the static Zipoy–Voorhees (ZV) metric valid for all values of the distortion parameter $$\gamma $$
γ
. In Schwarzschild coordinates, we investigate the effect of the charge in the newly found spacetime, stress the analogy with Reissner–Nordstrom metric and discuss some of its features. It is shown that from the expression of Weyl curvature, directional singularities become manifest. For astrophysical importance, we find lensing of null geodesics from the Gauss–Bonnet theorem in such non-spherically charged objects. To prepare the ground for our null, circular geodesics we consider the angular equation linearized about the symmetry plane $$\theta =\pi /2$$

θ

. This, in turn, suggests the distortion parameter (the ZV parameter) must be in the interval $$1/2<\gamma <1$$

. It is found that the lensing angle is highly dependent on the distortion parameter, and becomes decisive on the effect of the charge. For a class of charged compact stars, we plot the deflection angle versus the ratio of impact parameter to the radius of the star. Plots have revealed that for perfectly spherical compact stars, it is hard to identify the effect of electric/magnetic charge, but for non-spherical compact stars the effect of electric charge becomes apparent. For comparison, the same lensing angle has also been found for the stationary ZV metric in the equatorial plane. Our analysis indicates that depending on the value of $$\gamma $$
γ
, the stationary state induces counter effect on the bending angle and thus, when compared with the uncharged static ZV case, the bending angle decreases. The influence of the parameter $$\gamma $$
γ
on the gravitational redshift is also displayed.

Published: August 2022

ITSM, namely one of its most essential parts, the Service Desk, is a vital communication platform between users and the service provider. Good IT service management ensures the smooth run of the company operations and provides stable support for its employees in all technical matters. Companies also must not forget the knowledge management part of the ITSM process. Knowledge must be available at the right time to the right people to ensure quality service. There are several tools, methods and techniques used in knowledge management. In this paper, we describe and propose an enhancement of selected tools and processes, namely call ticketing system and on-the-job training, as those are essential parts of the ITSM practice.
Pose- and Attribute-consistent Person Image Synthesis
Authors: Xu Cheng , Chen Zejun , Mai Jiajie , Xu Xuemiao , He Shengfeng
Published: August 2022

Person Image Synthesis aims at transferring the appearance of the source person image into a target pose. Existing methods cannot handle large pose variations and therefore suffer from two critical problems: (1) synthesis distortion due to the entanglement of pose and appearance information among different body components and (2) failure in preserving original semantics (e.g., the same outfit). In this article, we explicitly address these two problems by proposing a Pose- and Attribute-consistent Person Image Synthesis Network (PAC-GAN). To reduce pose and appearance matching ambiguity, we propose a component-wise transferring model consisting of two stages. The former stage focuses only on synthesizing target poses, while the latter renders target appearances by explicitly transferring the appearance information from the source image to the target image in a component-wise manner. In this way, source-target matching ambiguity is eliminated due to the component-wise disentanglement of pose and appearance synthesis. Second, to maintain attribute consistency, we represent the input image as an attribute vector and impose a high-level semantic constraint using this vector to regularize the target synthesis. Extensive experimental results on the DeepFashion dataset demonstrate the superiority of our method over the state of the art, especially for maintaining pose and attribute consistencies under large pose variations.

Published: August 2022

In recent years, the social economy has achieved remarkable development, and the income of residents has increased substantially. With the increasing income, residents begin to pursue a high quality of life, and the ways of entertainment also begin to become diversified. In this context, leisure sports have gradually come into the public’s view, and more and more people have started to participate in leisure sports. Aerobic gymnastics, as a popular form of fitness, is an important carrier to carry out national fitness sports and promote national health, and the development of national fitness sports cannot be carried out without scientific and effective aerobic gymnastics teaching, training, and guidance. At the present stage, the traditional aerobics teaching content and teaching methods of leisure sports majors are difficult to meet the needs of students learning. Therefore, the hybrid teaching system of aerobics classes based on cloud computing and neural networks is proposed, which combines the advantages of a network teaching and traditional teaching to comprehensively and effectively improve the efficiency and quality of aerobics teaching and improve the classroom teaching effect. At the same time, it promotes leisure sports students to systematically master the basic theoretical knowledge, skills, and methods, improve the comprehensive ability of independent learning and inquiry learning, have the ability of leisure sports program guidance and aerobics teaching organization, enhance their employability, and cultivate “multidiscipline” students who can adapt to the needs of the times and engage in technical guidance of aerobics and participate in leisure sports market services in leisure fitness clubs, industry associations, and educational institutions. This course aims to cultivate “multidiscipline” applied talents who can work in leisure and fitness clubs, industry associations, and educational institutions.

Published: August 2022

Objective. To investigate the ultrasound characteristics and clinical efficacy of coronary arteries before and after immune blocking therapy with gamma globulin in children with Kawasaki disease. Methods. A total of 64 children with Kawasaki disease who were treated in our hospital from January 2018 to October 2021 were selected. All the children were given immune blocking therapy with gamma globulin on the basis of conventional treatment. The disappearance time of related symptoms and signs (fever, mucosal congestion, cervical lymphadenopathy, and swelling of the hands and feet) in children were counted. The white blood cell count (WBC), platelet count (PLT), C-reactive protein (CRP), and procalcitonin (PCT) levels of the children before and after treatment were compared, and the characteristics of coronary echocardiography before and after treatment were observed for analysis and discussion, to carefully observe whether the coronary artery involvement of the children was improved. Results. The inner diameter of the left and right coronary arteries significantly decreased (

P
<

Published: August 2022

B7-H5, an immune checkpoint molecule, is markedly upregulated in multiple cancers and plays an important role in tumor progression and immune escape. However, the expression and significance of soluble B7-H5 (sB7-H5) in cancer remain unclear. Herein, we generated two novel mouse anti-human B7-H5 monoclonal antibodies (mAbs) 2E5 and 7B10, which had different epitopes. Based on the two mAbs, a sandwich enzyme-linked immunosorbent assay (ELISA) system was developed. Using this ELISA, we found that compared with healthy controls (HCs), sB7-H5 levels were significantly increased in the serum of patients with gastric cancer (GC), colorectal cancer (CRC), and lung cancer (LC) and were associated with TNM stage and metastasis. Receiver operating characteristic (ROC) curve analysis showed that sB7-H5 has diagnostic value for GC, CRC, and LC. Collectively, our findings delineate that sB7-H5 may be used as a predictor for diagnosis of cancer and a potential therapeutic target for cancer treatment.
Immunoecology of Species with Alternative Reproductive Tactics and Strategies
Authors: Lozano George A. , Ros Albert F. H.
Published: August 2022

Alternative reproductive tactics and strategies (ARTS) refer to polymorphic reproductive behaviours in which in addition to the usual two sexes, there are one or more alternative morphs, usually male, that have evolved the ability to circumvent direct intra-sexual competition. Each morph has its own morphological, ecological, developmental, behavioural, life-history, and physiological profile that shifts the balance between reproduction and self-maintenance, one aspect being immunity. Immunoecological work on species with ARTS, which is the topic of this review, is particularly interesting because the alternative morphs make it possible to separate the effects of sex per se from other factors that in other species are inextricably linked with sex. We first summarize the evolution, development, and maintenance of ARTS. We then review immunoecological hypotheses relevant to species with ARTS, dividing them into physiological, life-history, and ecological hypotheses. In context of these hypotheses, we critically review in detail all immunoecological studies we could find on species with ARTS. Several interesting patterns emerge. Oddly, there is a paucity of studies on insects, despite the many benefits that arise from working with insects: larger sample sizes, simple immune systems, and countless forms of alternative reproductive strategies and tactics. Of all the hypotheses considered, the immunocompetence handicap hypothesis has generated the greatest amount of work, but not necessarily the greatest level of understanding. Unfortunately, it is often used as a general guiding principle rather than a source of explicitly articulated predictions. Other hypotheses are usually considered a posteriori, but perhaps they should take centre stage. Whereas blanket concepts such as “immunocompetence” and “androgens” might be useful to develop a rationale, predictions need to be far more explicitly articulated. Integration so far has been a one-way street, with ecologists delving deeper into physiology, sometimes at the cost of ignoring their organisms’ evolutionary history and ecology. One possible useful framework is to divide ecological and evolutionary factors affecting immunity into those that stimulate the immune system, and those that depress it. Finally, the contributions of genomics to ecology are being increasingly recognized and sometimes applied to species with ARTS, but we must ensure that evolutionary and ecological hypotheses drive the effort, as there is no grandeur in the strict reductionist view of life.
Environmental Accounting System Model Based on Artificial Intelligence Blockchain and Embedded Sensors
Authors: Zhang Wenyu , Zhu Mengpu
Published: August 2022

With the rapid development of communication technology and automation technology, sensors are becoming more and more intelligent. This study proposes an environmental accounting system model based on artificial intelligence blockchain and embedded sensors. A high-precision sensor system based on embedded technology is first built, which not only avoids the shortcomings of analog data transmission, but also has high performance and price advantages. At the same time, it can be easily combined into a simple sensor network, and array measurement can be realized through the development of blockchain technology. However, the current blockchain system has the disadvantage of storage limitation. The problem is particularly serious when a large amount of data needs to be stored in the blockchain, especially when the blockchain is combined with big data. As a comprehensive field of accounting, ecology, and environmental science, environmental accounting has made great contributions to sustainable development in the field of accounting. The theoretical research in the field of environmental accounting in China started late, and a unified environmental accounting system has not actually been established. Under the conditions of immature theoretical and policy basis, companies have almost no actual surveys on environmental accounting. The characteristics of blockchain technology, such as decentralization, transparency, and changes in information unavailability, can fully solve the problem that the current accounting information system cannot consolidate transaction information and the accounting process. The reliability assurance mechanism of the accounting information system based on blockchain technology can greatly ensure the reliability of the accounting information system, effectively suppress accounting fraud, and improve the transparency of information.

Authors: Li Lin
Published: August 2022

The traditional template scheduling method provides designers with design materials that do not reflect the real intention of designers, and a plane method based on three-dimensional virtual vision technology is proposed. In the given development environment, the mouse uses hand drawing, and the handwriting is formed by the obtained point sequence. The hand drawing adopts the method of smoothing noise to eliminate the noise, and the hand drawing stroke adopts two loops. The virtual model is drawn into 3D manually to realize the graphic design. After establishing the three-dimensional graphic design model, the visual effect is improved by using color mapping. The experiments show that this method can effectively realize the three-dimensional virtual model based on manual drawing, make the three-dimensional effect more real, meet the requirements of designers, and help designers show the real intention of design.

Published: August 2022

The utilization of natural fibre-based biodegradable polymers has expanded in the present circumstances since natural fibres are relatively inexpensive, recyclable, lighter, nonflammable, and harmless. However, hydrophilic nature is the most serious issue. To address this issue, the current study was applied to enhance the material characteristics of hybrid composites strengthened by CGF and nanosilica powder. To accomplish the mentioned goal, RSM calculated and optimized the following processing parameters using the BBD arrangement at various CGF fibre thickness (gsm), weight percent of nanosilica powder (wt. percent), and cryogenic treatment period (min). To prevent hydrophilic nature, the fibres were pretreated for four hours with a 5% alkaline solution. Deterioration models were created to analyze the material characteristics, and the optimal progression variables were determined. Based on the multiresponse surface methodology, the governable process variables for nano-silica- and CGF-based hybrid nanocomposites should be set at 3% silica, 300 gsm of CGF, and 30 minutes of cryogenic treatment. The tension, bending, and impact property correlation coefficient values ([Formula: see text]) are 0.95, 0.94, and 0.95, respectively. The above-mentioned combinations provide better water absorption and mechanical strength.
Peptidoglycan-Mediated Bone Marrow Autonomic Neuropathy Impairs Hematopoietic Stem/Progenitor Cells via a NOD1-Dependent Pathway in db/db Mice

Published: August 2022

Impairment of bone marrow-derived hematopoietic stem/progenitor cells (HSPCs) contributes to the progression of vascular complications in subjects with diabetes. Very small amounts of bacterial-derived pathogen-associated molecular patterns (PAMPs) establish the bone marrow cell pool. We hypothesize that alteration of the PAMP peptidoglycan (PGN) exacerbates HSPC dysfunction in diabetes. We observed increased PGN infiltration in the bone marrow of diabetic mice. Exogenous administration of PGN selectively reduced the number of long-term repopulating hematopoietic stem cells (LT-HSCs), accompanied by impaired vasoreparative functions in db/db mouse bone marrow. We further revealed that bone marrow denervation contributed to PGN-associated HSPC dysfunction. Inhibition of NOD1 ameliorated PGN-induced bone marrow autonomic neuropathy, which significantly rejuvenated the HSPC pools and functions in vivo. These data reveal for the first time that PGN, as a critical factor on the gut-bone marrow axis, promotes bone marrow denervation and HSPC modulation in the context of diabetes.

The traditional antidiabetic plant Viscum album (V. album) was collected from the oak plant in the wild at Maidan, Khyber District, of Pakistan, for assessment of its antidiabetic potential and phytochemical profile. Lowering of blood glucose level, antioxidant effect, lipids proﬁle, liver function marker enzymes, and kidney function markers were evaluated in extract and glibenclamide treated groups, in normal as well as in diabetic control groups. An elevated level of blood glucose level, lipids (Cholesterol, TG, LDL), liver function marker enzymes (ALT, AST, ALP), and kidney function markers (bilirubin, creatinine, urea) were observed in alloxan-induced diabetic rats; however, a HDL level was decreased. Administration of V. album hydroalcoholic extract for 28 days renovated significantly (p<0.05) all the above biochemical parameters. The antioxidant enzymes SOD, CAT, and GPX were also considerably restored. In vitro, antioxidant assay indicated that the extract of 2,000 µg/mL scavenges free radicals of DPPH 68.4%, ABTS 69.5%, and H2O2 50.6%. The extracts revealed the presence of saponins, flavonoids, alkaloids, terpene, tannins, phenols, protein, amino acids, sterols, and glycosides. The extract has shown phenolic contents 421 ± 4.8 mg GAE/100 g d. w and flavonoids content 127 ± 1.4 mg equiv. Rut/100 g d. w. The findings of this research recommend V. album could be a potent source of natural antidiabetic constituents.

PDL (Phoenix dactylifera leaves) is widely spread in Iraq and is known to be rich in phytochemicals as flavonoids, saponins, tannins, glycosides, oils, and lipids. The effect of PDL extract in reducing the corrosion of Aluminium in 1 M HCl solution using a weight loss technique, and computational chemistry calculations were investigated in this study. The study carried out at different temperatures (20, 30, 40, and 50) in the presence of plant extract and the absence of extract. A number of parameters were included to be detected in this study according to the density functional theory (DFT)/P3LYP/6-311G, including the highest occupied molecular orbital EHOMO, the lowest unoccupied molecular orbital ELUMO, energy gapΔE, softnessS, hardnessη, dipole momentμ, electronegativityχ, electrophilicityω, inhibitor-metal interaction energy∆ψ, and electrons transferred fractionΔN. Two adsorption isotherms were used to explain inhibitor adsorption behavior. Two adsorption isotherms were used to explain inhibitor adsorption behavior, the Freundlich adsorption isotherm and the Langmuir adsorption isotherm, the Freundlich adsorption isotherm was discovered to be followed by the inhibitor with correlation coefficient values ranging from 0.98 to 0.94 with temperature increased from 20 to 50 degrees Celsius. The adsorption mechanism includes a physical adsorption process. The results showed that with the increment of the inhibitors concentration, there was an improvement of the inhibition efficiency. The most outstanding inhibitor efficiency was 97.7% at 10 mL/L inhibitor concentration.

Published: August 2022

The COVID-19 pandemic has caused a worldwide catastrophe and widespread devastation that reeled almost all countries. The pandemic has mounted pressure on the existing healthcare system and caused panic and desperation. The gold testing standard for COVID-19 detection, reverse transcription-polymerase chain reaction (RT-PCR), has shown its limitations with 70% accuracy, contributing to the incorrect diagnosis that exaggerated the complexities and increased the fatalities. The new variations further pose unseen challenges in terms of their diagnosis and subsequent treatment. The COVID-19 virus heavily impacts the lungs and fills the air sacs with fluid causing pneumonia. Thus, chest X-ray inspection is a viable option if the inspection detects COVID-19-induced pneumonia, hence confirming the exposure of COVID-19. Artificial intelligence and machine learning techniques are capable of examining chest X-rays in order to detect patterns that can confirm the presence of COVID-19-induced pneumonia. This research used CNN and deep learning techniques to detect COVID-19-induced pneumonia from chest X-rays. Transfer learning with fine-tuning ensures that the proposed work successfully classifies COVID-19-induced pneumonia, regular pneumonia, and normal conditions. Xception, Visual Geometry Group 16, and Visual Geometry Group 19 are used to realize transfer learning. The experimental results were promising in terms of precision, recall, F1 score, specificity, false omission rate, false negative rate, false positive rate, and false discovery rate with a COVID-19-induced pneumonia detection accuracy of 98%. Experimental results also revealed that the proposed work has not only correctly identified COVID-19 exposure but also made a distinction between COVID-19-induced pneumonia and regular pneumonia, as the latter is a very common disease, while COVID-19 is more lethal. These results mitigated the concern and overlap in the diagnosis of COVID-19-induced pneumonia and regular pneumonia. With further integrations, it can be employed as a potential standard model in differentiating the various lung-related infections, including COVID-19.

Published: August 2022

In order to study the dynamic characteristics of the nonlinear system of the maglev train, a vibration model of the two-degree-of-freedom nonlinear suspension system of the maglev train is established in this paper. Based on the linearized model of the suspension control module, the suspension system is controlled by the state feedback method. Compared with the results of the Runge–Kutta method, the accuracy of the settlement results is verified. This paper analyzes the influence of system parameters and feedback control parameters on the system. The results show that the linear stiffness mainly affects the left-right migration of the resonance peak and the difference between the maximum and minimum of the resonance region of the suspension frame; the nonlinear stiffness mainly affects the slope of the resonance region of the car body and the suspension frame; displacement feedback control parameters can reduce the amplitude of the system, velocity feedback control parameters can make the state change of the suspension frame more smoothly, and acceleration feedback control parameters make the car body and the suspension frame have a strong coupling effect. According to the Hurwitz criterion of Hopf bifurcation, this paper deduces the conditions that the control parameters should satisfy when the equilibrium point is stable, and the instability produces periodic vibration under PID control. Through numerical simulation, it is found that the system has complex dynamic behavior, the results show that the system works under some conditions, and there are multiple stable and unstable limit cycles simultaneously. Therefore, the system will appear alternately between multiperiod and chaotic motion, which will affect the stability of the system.

Published: August 2022

A 3-year-old male entire Boxer was presented for a 6-day history of progressive symmetric nonambulatory tetraparesis with diffuse spinal hyperesthesia. Eight days prior to admission, the dog ingested warfarin accidentally, exhibiting systemic clinical signs of intoxication 2 days later. Upon referral, the dog was nonambulatory with paretic thoracic limbs and plegia with absent nociception on pelvic limbs, spinal reflexes were decreased to absent in all four limbs, and urinary and faecal incontinence were noticed. Magnetic resonance imaging (MRI) of the cervical, thoracic, and lumbar regions of the vertebral column revealed intramedullary lesions extending from the first cervical segments to the conus medullaris consistent with extensive intramedullary haemorrhages. Despite management with vitamin K1 and physiotherapy, 6 weeks later, improvement was limited to thoracic limb motor function, and euthanasia was elected. This case reports an extensive presumptive haematomyelia with severe neurological deficits suspected to be secondary to warfarin intoxication in a dog.

Objective. To explore the validity and accuracy of electrochemiluminescence immunoassay (ECLIA) and enzyme-linked immunosorbent assay (ELISA) in the serological detection of the hepatitis B virus. Methods. From 6 February 2019 to 1 March 2020, 96 patients diagnosed with hepatitis B virus infection in our hospital were recruited and assigned at a ratio of 1 : 1 to experimental groups A (GA) and B (GB), with 48 cases in each group, and the five major serological indicators of hepatitis B were tested and analyzed using ECLIA and ELISA. In addition, 50 suspected patients were selected for two tests, respectively, to compare the accuracy of the two test methods. Results. ECLIA was associated with significantly higher expression levels and higher detection rates of HBeAg, HBeAb, HBsAg, and HBsAb versus ELISA (

P
<
0.05

), and the difference in the expression and detection rates of HBcAb levels between the two groups did not come up to the statistical standard (

P
>

La aspergilosis broncopulmonar alérgica (ABPA) es una enfermedad inflamatoria de las vías respiratorias, de origen inmunitario, que afecta principalmente a pacientes con fibrosis quística (FQ) y, con menor frecuencia, a pacientes con asma. La ABPA puede causar lesiones pulmonares irreversibles y bronquiectasias si no se trata de forma temprana y activa. Los esteroides orales a largo plazo, el tratamiento estándar para la ABPA, se asocian con un riesgo mayor de efectos secundarios y un posible incumplimiento de la medicación. Se ha utilizado un bolo mensual de metilprednisolona intravenosa (IV-PS) como alternativa a los esteroides orales para tratar la ABPA vinculada con la FQ, y se ha reportado una respuesta clínica similar y menos efectos secundarios relacionados con los esteroides. Hasta donde sabemos, no se ha reportado el uso de la IV-PS en la ABPA asociada con asma. Presentamos el tratamiento exitoso de ABPA relacionada con asma en un adolescente, utilizando un bolo de metilprednisolona intravenosa combinado con itraconazol oral, sin efectos secundarios significativos debidos a los esteroides.

Introduction: The aim of this study was to investigate and compare the anterior segment biometrics in high myopia and control groups. Methods: Thirty-four eyes of 34 high myopia patients and 42 eyes of 42 control subjects were included. Schlemm’s canal (SC) area, trabecular meshwork (TM) thickness and length, scleral spur (SS) length, and anterior scleral thickness (AST) were measured using swept-source optical coherence tomography. Associations between SC area, TM thickness, TM length, SS length, and AST were also estimated. Results: SC area, TM thickness, and SS length were significantly associated with AST0 (AST at 0 mm from SS) in both high myopia and control groups. AST0 (702.61 ± 78.05 vs. 729.12 ± 95.87 μm, p = 0.085) and SS length (206.25 ± 52.25 vs. 212.09 ± 51.86 μm, p = 0.556) were not significantly different between high myopia and control groups, whereas SC area (6,622.68 ± 1,130.06 vs. 6,105.85 ± 1,297.84 μm2, p = 0.015) was significantly greater and TM thickness (96.15 ± 34.40 vs. 107.93 ± 29.97 μm, p = 0.048) was significantly thinner in high myopia group than in control group. Conclusion: SC area and TM thickness were significantly associated with AST0, while AST0 and SS length were not significantly different between high myopia and control groups. The changes in SC and TM dimensions in high myopia eyes might be caused by factors other than AST0 and SS length.
Os estudos egiptológicos de Charles S. Peirce
Authors: Kammerzell Frank , Lapčić Aleksandra , Nöth Winfried , Sancassani Victor
Published: August 2022

O artigo realiza um levantamento e apresenta uma análise crítica dos estudos de Peirce em egiptologia de 1885 a 1904, como documentados principalmente nos MSS 1227, 1228, 1244 e 1294. São examinados os estudos de Peirce e seus avanços em língua e escrita do Egito Faraônico, bem como suas análises das realizações científicas dos antigos egípcios. Entre os tópicos linguísticos em foco estão os pressupostos de Peirce a respeito da iconicidade da escrita hieroglífica, suas conjecturas sobre a origem das palavras indexicais a partir dos substantivos e suas hipóteses relativas à proximidade do egípcio antigo à protolíngua humana. O artigo delineia algumas das hipóteses de Peirce relacionando a estrutura do egípcio aos seus pressupostos fundamentais acerca da iconicidade e indexicalidade na língua. Ao que tudo indica, Peirce não só estava muito familiarizado com o estado da arte da egiptologia contemporânea, como também alcançou uma notável competência na língua egípcia e na sua escrita hieroglífica. Enquanto alguns dos insights de Peirce a respeito da língua e da civilização dos egípcios antigos são ainda sustentáveis hoje, outros refletem certos equívocos da erudição de seu tempo, que exigem correção à luz do estado da arte na egiptologia atual.
Los paisajes funerarios de Amarna, Tebas y Menfis en el contexto de la reforma de Amarna
Authors: Iamarino Maria Laura
Published: August 2022

Las modificaciones desarrolladas en el Egipto antiguo antes, durante y después de Akhenatón están relacionadas con la reforma religiosa y su ejecución, corolario de un proceso cuyo objetivo era la centralización del poder político. Durante los gobiernos de Amenhotep III y Amenhotep IV (Akhenatón) este proceso derivó en el traslado de la capital a Amarna. La restauración iniciada por Tutankhamón debe considerarse como una reorganización ante los cambios efectuados previamente. Se propone, aquí, analizar el uso de espacios, en este caso en particular haciendo foco en los funerarios, previendo que las necrópolis de Amarna, Tebas y Menfis evidencian diferencias, además de, marcadas continuidades con respecto de los períodos previos.
A Calábria grega: expansão territorial da pólis de Lócris. Apontamentos preliminares
Authors: Florenzano Maria Beatriz Borba
Published: August 2022

O Ocidente mediterrânico, a partir do século VIII a.C., passou a receber levas de migrantes gregos dispostos a ali se instalarem permanentemente. Levados pela falta de terras agriculturáveis, por problemas políticos em seus locais de origem ou, ainda, pela busca de um modo de vida ligado à atividade comercial, esses grupos, por força, tiveram que estabelecer relações com os habitantes das localidades do Ocidente. Fundando assentamentos de vários tipos – uns mais permanentes, outros mais temporários –, os gregos tornaram-se parceiros de sicânios, sículos, samnitas, fenícios, enótrios e assim por diante em relações muitas vezes de agressão, mas em outras de convívio pacífico, de acomodação, de negociação. Nesse contexto, uma leva de migrantes da Lócrida da Grécia Balcânica chegou ao extremo sul da Península Itálica, pelo lado do mar Jônio, e fundaram uma nova Lócris no século VII a.C.: Lócris Epizefiri. Ao depararem-se com uma faixa costeira muito estreita, esses lócrios logo se aventuraram pelas montanhas do Aspromonte em direção ao mar Tirreno: ali encontraram uma planície muito fértil, onde fundaram dois novos assentamentos: Medma e Hipónio. Neste artigo, procuraremos mostrar o que a Arqueologia revela sobre como essas novas pólis na planície tirrênica de Gioia Tauro se constituíram, ampliando a área de influência de Lócris.
Os campos de integração em Delos no período helenístico (167-69 a.C.): apontamentos para uma História Antiga Global
Authors: Morales Fabio Augusto
Published: August 2022

Este artigo discute, do ponto de vista teórico e historiográfico, o problema da relação entre as cidades e os processos de integração no período helenístico na chave da História Antiga Global. Para isso, está dividido em cinco partes: uma breve apresentação do problema a partir do caso de Delos no período helenístico; o balanço crítico da historiografia sobre as cidades helenísticas nas últimas décadas; a análise de duas propostas de modelos interpretativos (de Vlassopoulos e Guarinello) para a história das globalizações/processos de integração na antiguidade; a proposição de um modelo centrado na categoria de campo; um exercício de aplicação do modelo proposto ao caso de Delos durante a Segunda Dominação Ateniense (167-69 a.C.). O texto argumento pela utilidade da categoria de campo, inspirada nas reflexões de Bourdieu e associada às propostas acima mencionadas, para a reflexão sobre a complexidade dos processos de integração sem perder de vista as sociedades enquanto totalidades.
El circuito osiriano en TT49: iconografía, epigrafía y simbolismo en una tumba de transición
Authors: Bonanno Mariano
Published: August 2022

La figura y el mundo osirianos, neutralizados por Akhenaton, tienen como contrapartida una reacción plasmada en la reacción integral postamarniana. Esta respuesta involucra tanto el repertorio iconográfico expreso en las representaciones de las tumbas y en el registro epigráfico. De este modo, y allende la figura osiriana estrictamente, la concepción del Más Allá recobra un lugar antes anulado durante el interregno amarniano. La tumba de Neferhotep (TT49), datada en el reinado del faraón Ay (c.a.1323-1320), es por ello una tumba de transición que ofrece características estilísticas extraordinarias. Lo que aquí se propone es un análisis pormenorizado de la presencia del dios Osiris en las representaciones bidimensionales, así como en el registro epigráfico en el contexto de la tumba. Luego, enfatizando en la capilla en particular será presentada una interpretación del simbolismo que vincula al pilar sudoeste con la pared sur del nicho de las estatuas y la estela de la pared oeste, lado sur.

Ambos se apresentam como alternativas às antigas grandes narrativas centradas na História da Grécia e de Roma, como novas unidades de estudo. O artigo explora seus alcances e limites conceituais, tendo em vista a dupla lente da unidade e da diversidade no estudo das sociedades humanas.
Conductance Artery Wall Layers and Their Respective Roles in the Clearance Functions
Authors: Michel Jean-Baptiste , Lagrange Jeremy , Regnault Veronique , Lacolley Patrick
Published: August 2022

Evolutionary organization of the arterial wall into layers occurred concomitantly with the emergence of a highly muscularized, pressurized arterial system that facilitates outward hydraulic conductance and mass transport of soluble substances across the arterial wall. Although colliding circulating cells disperse potential energy within the arterial wall, the different layers counteract this effect: (1) the endothelium ensures a partial barrier function; (2) the media comprises smooth muscle cells capable of endocytosis/phagocytosis; (3) the outer adventitia and perivascular adipocytic tissue are the final receptacles of convected substances. While the endothelium forms a physical and a biochemical barrier, the medial layer is avascular, relying on the specific permeability properties of the endothelium for metabolic support. Different components of the media interact with convected molecules: medial smooth muscle cells take up numerous molecules via scavenger receptors and are capable of phagocytosis of macro/micro particles. The outer layers—the highly microvascularized innervated adventitia and perivascular adipose tissue—are also involved in the clearance functions of the media: the adventitia is the seat of immune response development, inward angiogenesis, macromolecular lymphatic drainage, and neuronal stimulation. Consequently, the clearance functions of the arterial wall are physiologically essential, but also may favor the development of arterial wall pathologies. This review describes how the walls of large conductance arteries have acquired physiological clearance functions, how this is determined by the attributes of the endothelial barrier, governed by endocytic and phagocytic capacities of smooth muscle cells, impacting adventitial functions, and the role of these clearance functions in arterial wall diseases.
