Co-pyrolysis of various plastic waste components as an environmentally sustainable source of alternative fuels
Authors: Jovancicevic Ivana , Antic Malisa , Gajica Gordana , Schwarzbauer Jan
Published: April 2024

In this study, pyrolysis and co-pyrolysis of commonly used plastic materials (polyethylene terephthalate ? PET, high density polyethylene ? HDPE, and polystyrene ? PS) were conducted to analyse the chemical composition of the corresponding pyrolyzates. Different ratios of plastic materials were applied to obtain a composition of aliphatic and aromatic degradation products that closely resemble those of conventional fossil fuels. The systematic chemical variations can act as base for evaluating this approach as a sustainable source of alternative fuels. HDPE revealed an aliphatic composition of degradation products, while PS and PET produced only aromatic compounds. Quantitative analysis of the obtained pyrolyzates revealed a clear correlation of initial proportion with the resulting quantitative product composition. The generation of individual pyrolysis products gave a high reproducibility. However, it became evident that the decomposition products of PS consistently emerged as the most prominent among all tested HDPE/PS mixtures. The ratio of HDPE:PS = 1:3 showed 96 % of the aromatic compounds as PS decomposition products. PET revealed a oxygen containing structure of the products, contributing to 83 % of the HDPE:PET = 1:3 mixture. These results gain insights into the potential of plastic waste as a sustainable source for alternative fuels and valuable chemicals.

Published: April 2024

High-entropy ceramic materials usually refer to the multi-principal solid
solution formed by 5 or more ceramic components. Due to its novel
?high-entropy effect? and excellent performance, it has become one of the
research hotspots in the field of ceramics in recent years. As the research
system of high-entropy ceramics has gradually expanded from the initial rock
salt oxides (Mg-Ni-Co-Cu-Zn)O to fluorite oxides, perovskite oxides, spinel
oxides, borides, carbides and silicates, its special mechanical, electrical,
magnetic and energy storage properties have been continuously discovered.
Based on the basic principle of high-entropy materials, this paper mainly
introduces the prominent perovskite-type oxide high-entropy ceramics in
recent years from the perspective of ceramic structure and properties, and
predicts the development trend of high-entropy perovskite-type ceramics in
the next few years.

Authors: Rini Ari , Simatupang Mediniah , Rati Yolanda , Dewi Rahmi
Published: April 2024

In this work, ZnO-based powders were synthesized by a simple biosynthesis
method using matoa leaf extract and microwave irradiation. The pure ZnO was
modified with selenium doping (5, 10 and 15 at.%) to improve the
photocatalytic capability in degrading 4-nitrophenol. The synthesized
powders had wurtzite structure and XRD analysis demonstrated a change in ZnO
lattice parameters with Se doping. Granular surface morphology and decrease
in particle size with Se doping were observed by using FESEM. Meanwhile, EDX
confirmed the presence of Zn, O and Se elements in the doped samples and BET
analysis showed that the specific surface area ranged from 10 to 18m2/g. The
observed strong absorption in UV region decreases with Se doping from 367 to
357 nm and is accompanied by an increase in the bandgap energy from 3.14 to
3.23 eV. Under UV irradiation, the ZnO powder doped with 5 at.% Se revealed
the highest degrading reaction rate of ?0.0218min?1 and photocatalytic
efficiency of 88.4% compared to other samples. Therefore, it was shown that
an optimal amount of Se and simple biosynthesis route can enhance the
photocatalytic capability of ZnO.

Authors: Lather Aryan , Poonia Kanika , Kundu R. , Ahlawat Neetu , Nehra Anuj , Kaur Shubhpreet
Published: April 2024

Cu2+ and Er3+ doped BaZr0.05Ti0.95O3 (BZT) ceramics were prepared using the
solid-state reaction method, where amount of CuO + Er2O3 was fixed at 2 wt.%
and different CuO : Er2O3 molar ratios (i.e. 1:1, 1:2, 1:3, 2:1 and 3:1)
were used. The influence of Cu2+ and Er3+ doping on crystal structure and
dielectric properties of the samples sintered at 1300 ?C was investigated.
X-ray diffraction analysis confirmed the formation of a single-phase
material and tetragonal crystal structure with P4mm symmetry.
Microstructural analysis conducted with a scanning electron microscope
revealed well-defined and uniformly distributed grains across the surface of
the sintered samples and reduction of grain size and density with doping.
The highest energy storage density of 40.51mJ/cm3 with an energy efficiency
of 78.8% was obtained in the sample with CuO : Er2O3 molar ratio of 2:1. The
doped BZT ceramics have high dielectric constant and significantly lower
tangent loss in comparison to the undoped BZT. The dielectric data confirm
the non-Debye behaviour for all the samples. Impedance spectroscopy and
electrical modulus analysis indicated that conduction in the materials was
influenced by both the grains and grain boundaries. The AC conductivity is
described by the Jonscher?s universal power law, whereas DC conductivity
follows a dependency based on the Arrhenius?s theory. The results revealed a
conduction mechanism characterized by non-overlapping small Polaron
tunnelling up to 340?C and a transition to correlated barrier hopping
conduction above 340?C within the selected temperature range for all the
samples. According to the Arrhenius fitting of DC conductivity the
activation energy of the undoped BaZr0.05Ti0.95O3 sample is 0.168 eV and
decrease with doping to 0.138 and 0.131 eV for the sample with lower Cu2+
contents (CuO : Er2O3 molar ratios of 1:2 and 1:3, respectively).
The influence of vanadium and titanium oxides in slag on the wetting and corrosion of dense Al2O3 ceramics
Authors: Liu Zhaoyang , Gao Yuqing , Pan Songyang , Zhang Ruinan , Gao Wei , Wen Tianpeng , Ma Beiyue , Yu Jingkun
Published: April 2024

The present study investigates the wetting and corrosion behaviour of slags
on dense Al2O3 ceramics, focusing on the influence of varying vanadium- and
titanium oxide content. Physicochemical properties of the slag were assessed
by measuring wetting angles, heights and diameters of the molten slags on
the alumina at different temperatures. Microscopic observations and
elemental composition analysis were conducted on the interface between the
corroded Al2O3 ceramics and the slags. Our findings demonstrated that the
V2O3 addition in the slag leads to its oxidation to V2O5, which further
reacts with Fe2O3 and MnO to form low melting point phases such as FeVO4 and
MnVO6. Consequently, the melting point of the slag decreases significantly,
resulting in a decreased wetting angle with the Al2O3 ceramics. The presence
of unsaturated alumina in the slag leads to the dissolution of aluminium
ions from the ceramics into the slag, which reacts with Fe2O3 and MnO to
form spinel phases, contributing to material loss of the ceramics.
Infiltration of the slag into the Al2O3 predominantly occurs through the
alumina grain boundaries. Two types of infiltration are identified: one
involving reactions with alumina to form low melting point phases like Fe2O3
and the other involving inherent low melting point phases such as MnVO6. In
contrast, the penetration of SiO2 into the alumina substrate is limited.
Additionally, the dissolution of Al2O3 into the slag creates pathways for
further infiltration. This study highlights the significant influence of Ti
and V content on the physicochemical properties of the slag and provides
insight into the corrosion mechanism of Al2O3 ceramics by Ti and V
containing slags.
IRS Enforcement and Voluntary Tax Disclosure
Authors: Ehinger Anne C. , Lee Joshua A. , Stomberg Bridget , Towery Erin
Published: April 2024

Although voluntary tax disclosures can improve firms’ information environments and reduce financial statement users’ costs of processing complex tax information, they can also inform tax authorities about tax avoidance strategies. This study explores the content of voluntary tax disclosures during quarterly earnings announcements and conference calls to examine the effect of IRS enforcement on managers’ voluntary tax disclosure decisions. We estimate a negative relation between IRS enforcement and voluntary tax disclosures that is concentrated in the subset of firms with high levels of tax avoidance. These results are consistent with managers having concerns about the potential costs of voluntary disclosures to tax authorities. In supplemental analysis, we find results consistent with voluntary tax disclosures benefiting analysts, but at the cost of increasing IRS attention. Collectively, our results suggest an unintended negative effect of IRS enforcement on the information environment.

Objective. To investigate glucose metrics and identify potential predictors of the achievement of glycemic outcomes in children and adolescents during their first 12 months of MiniMed™ 780G use. Research design and methods. In this multicenter, longitudinal, real-world study, 368 children and adolescents with type 1 diabetes starting SmartGuard technology between June 2020 and June 2022 were recruited. Ambulatory glucose profile data were collected during a 15-day run-in period (baseline), two weeks after automatic mode activation, and every 3 months. The influence of covariates on glycemic outcomes after 1 year of Minimed™ 780G use was assessed. Results. After 15 days of automatic mode use, all glucose metrics improved compared to baseline (p<0.001), except for time below range and coefficient of variation (p=0.113 and p=0.330, respectively). After one year, time in range (TIR) remained significantly higher than at baseline (75.3% vs 62.8%, p<0.001). The mean glycated hemoglobin over the study duration was lower than the previous year (6.9 ± 0.6% vs 7.4 ± 0.9%, p<0.001). Time spent in tight range (70-140 mg/dl) was 51.1% and glycemia risk index was 27.6. Higher TIR levels were associated with a reduced number of automatic correction boluses (p<0.001), fewer SmartGuard exits (p=0.021), and longer time in automatic mode (p=0.030). Individuals with baseline HbA1c > 8% showed more relevant improvement in TIR levels (from 54.3% to 72.3%). Conclusions. Our study highlights the sustained effectiveness of Minimed™ 780G among youths with T1D. Findings suggest that even children and adolescents with low therapeutic engagement may benefit from SmartGuard technology.

The Challenges of the Design-Driven Biotech Resources and Unique Translational Tools to Manage Cardiac Self-Renewal and Regeneration to be utilized in Clinical Practice
Authors: Suchkov Sergey
Published: April 2024

The approaches securing cardiac regeneration in post-infarction period are not available to be practiced. The key problem is the identity of cells is born to generate functionally active cardiac myocytes replenishing those being lost during ischemia. Over the last years, stem cells (SCs) have been a promise for the cure of several diseases, including heart failures, not only due to their plasticity but also acting as paracrine modulators and influencing the affected tissue. Human SC-based therapy derivatives are extremely attractive for therapeutic development because they have direct pharmacologic utility in clinical applications, unlike any other adult cells. Moreover, SC derived paracrine factors are to suppress inflammation and apoptosis, whilst stimulating angiogenesis, and amplifying the proliferation and differentiation of resident cardiac SCs (CSCs). SC therapies are thus viable alternatives to canonical treatments with substantial therapeutic potential; market opportunities are huge as multiple product candidates are expected to be approved over the coming decade. In this review, we accumulated recent data in the field of cardiac regeneration after MI using the latest resources of personalized and precision medicine (PPM), and considered promising ways of targeting pharmacotherapy and regenerative medicine in the field of cardiac rehabilitation.

Published: April 2024

Relevance The number of amputations performed on patients with diabetic foot syndrome is increasing all over the world. Almost half of these operations are the so-called “minor amputations” carried out within the foot. The high recurrence rate of neuropathic ulcers, impaired biomechanics, and a decrease in the quality of life of patients after these surgeries encourage the study of this problem and the search for possible treatment options due to the capabilities of surgical treatment for post-amputation foot deformities.

Aim of study To evaluate the nature of surgical interventions for post-amputation foot deformities in patients with diabetic neuropathy.

Material and methods The literature search was carried out in the databases of medical publications PubMed, CyberLeninka, Google Scholar, Scopus, Medline, eLIBRARY among articles in English and Russian. The search was performed using the following terms: transmetatarsal resection, diabetic foot syndrome, transmetatarsal amputation, minor amputation.

Results Surgical treatment methods for deformities after amputation of part of the forefoot are widely presented in the world literature and are more studied. The possibilities of correcting foot deformities that occurred after amputation of the entire anterior section (from transmetatarsal amputation to the level of the Chopart`s joint) are less covered, this direction and methods have been studied to a lesser extent.

Conclusions Surgical methods for the correction of post-amputation foot deformities have firmly entered the wide international practice. Their effectiveness is confirmed by studies with a high level of evidence. Nevertheless, a wider, academic research of the problem of orthopedic status in patients with this pathology and the corresponding methods of surgical treatment is required.

Authors: Anisimov A. A. , Ivanov R. V. , Voronin M. V. , Spiridonov V. A.
Published: April 2024

Relevance In modern realities, medical workers, primarily representatives of surgical specialties, are increasingly faced with the need to have legal literacy, since medical activities associated with surgical practice are associated with high legal risks.

Aim of study Studying the legal training of surgeons in the Republic of Tatarstan based on the experience of participating in criminal proceedings in cases related to improper provision of medical care.

Material and methods During the period from May 15 to May 31, 2021, an anonymous survey of 124 surgeons from various medical organizations of the Republic of Tatarstan was conducted. The questionnaire consisted of 13 multiple-choice questions with an additional field for comments. The participation in the survey was voluntary, and the questions were devoted to the experience of participation in criminal proceedings in “medical” cases and the need for legal training in this matter.

Results Among those surveyed, 51.5% of respondents at least once during the years of their career gave explanations to law enforcement agencies regarding the unfavorable outcome of medical care, and 38.7% were directly involved in a criminal case. According to 52.2% of respondents, the most common reason for complaints to law enforcement agencies is the inadequacy/bad manners of patients. The vast majority of doctors surveyed are guided in their activities by currently existing procedures, orders, standards and clinical recommendations. However, more than 37% of doctors have no idea how to act in the event of a criminal case being initiated due to an unfavorable outcome of medical care, and for 71.0%, medico-legal training is “highly relevant”.

Conclusion The problem of criminal liability for improper provision of medical care for surgeons in the Republic of Tatarstan is extremely relevant. There is an urgent need to develop interdisciplinary formats for interaction between the medical, forensic and legal communities in order to improve the legal literacy of medical workers and reduce criminal risks in surgical practice.

Published: April 2024

The purpose of the work is to find out the embryological prerequisites and the time of the possible occurrence of malformations and congenital deformations of the human skull.Results. The growth and enlargement of the neurocranium is largely determined by the growth of the brain due to their close syntopy. By the end of the second year, the bones are connected by sutures. The neurocranium is embryologically divided into the vault, which is formed by membranous ossification, and the basis cranii, the bones of which are formed by cartilaginous osteogenesis. The initial development of the neurocranium depends on the formation of the brain and its surrounding membranes. The source of the germ of the outer layer is the mesoderm and ectomesenchyme of the neural crest, soon it is divided into the inner layer – endomeninx and outer – ectomeninx. The latter is further divided into the outer osteogenic layer, in which the ossification centers form the bones of the skull, and the inner layer of the dura mater. The centers of ossification form the frontal, parietal, occipital and temporal bones, and the intermediate areas form fibrous sutures and fontanelles. Usually, the sutures are joined at the end of the second year of life. Conclusions. Congenital deformities of the cerebral part of the skull are morphological manifestations of numerous hereditary syndromes and/or metabolic, teratogenic effects, lysosomal storage diseases, brain malformations, unfavorable factors during the fetal period of development: restriction of the intrauterine environment, weak muscle tone, torticollis, clavicle fracture, cervical spine anomalies, multiple pregnancy and bone mineralization disorders. For the differential diagnosis of congenital defects of the skull, along with the use of diagnostic three-dimensional medical imaging, it is necessary to carry out genetic screening.

Authors: Biletskyi S.V. , Sydorchuk L.P. , Petrynych O.A. , Kazantseva T.V.
Published: April 2024

Left ventricular hypertrophy (LVH) is one of the most important predictors of cardiovascular events in patients with arterial hypertension (AH). Literature data on the role of electrocardiography (ECG) in diagnosing left ventricular (LV) myocardial hypertrophy are presented. Recommendations of the European Society of Cardiology and the European Society of Hypertension from 2018 and International Clinical Protocols "Duodecim" state the following LVH criteria: Sokolov-Lyon criteria: SV1 + RV5 > 35 mm; wave R in lead aVL > 11 mm; SV1 ≥ 25 mm, RV5–V6 > 25 mm; Cornell voltage index: SV3 + RaVL >20 mm in women and >28 mm in men; Cornell product: the product of the Cornell voltage index and the duration of the QRS complex (RaVL + SV3) × QRS – for men and (RaVL + SV3 + 8) × QRS – for women. The criteria of LVH is the value of the Cornell product > 2440 mm×ms. However, ECG criteria for detecting LVH are not sensitive enough. Peguero JG, Lo Presti S, et al. (2017) developed a more accurate method of diagnosing LVH by measuring the amplitude of the deepest S wave (SD) in any individual lead and adding it to the amplitude of the S wave in lead V4 (SV4) [SD+ SV4]. When the sum of [SD+ SV4] exceeds 28 mm in men or 23 mm in women (Peguero-Lo Presti criteria), LVH can be diagnosed.Objective: to systematize modern literary data on electrocardiographic diagnosis of left ventricular myocardial hypertrophy. Conclusion. Due to its low cost, easy availability, reproducibility and high specificity, electrocardiography remains the simplest and most common method of diagnosing myocardial hypertrophy. The Peguero-Lo Presti criteria for diagnosing left ventricular hypertrophy are more sensitive and specific than the voltage criteria of Sokolov-Lyon and Cornell.

Published: April 2024

Diabetes mellitus (DM) is one of the significant medical and social problems of modern society, which is due to high morbidity and prevalence, frequent occurrence of chronic micro- and macrovascular complications. Coronary heart disease (CHD) in patients with type 2 diabetes is 2-4 times more common than in people of the same age without diabetes [1]. In the absence of apparent signs of atherosclerosis, the risk of developing coronary artery disease in the next 10 years is 30% [2]. To date, the course and prognosis of this group of patients have not been sufficiently studied, objective clinical and diagnostic criteria for the development of complications of myocardial infarction have not been developed, and the problem of choosing pathogenetically based methods of treatment of CHD in combination with type 2 diabetes remains unresolved [3].The aim of the work was to investigate the informativeness of Holter monitoring (HM), the correlation of HM indicators, C-reactive protein (CRP) and carbohydrate metabolism in patients with stable coronary heart disease (CHD) in combination with type 2 diabetes for the prognosis of the course of this pathology, timely individual treatment and prevention occurrence of endpoints.Material and methods. The study involved 95 patients with coronary heart disease with angina pectoris functional class (FC) III and heart failure (HF FC III with a preserved left ventricular ejection fraction (LVEF); of them, 60 patients had concomitant type 2 DM in the compensation stage.Results. In patients with comorbidity (a combination CHD and type 2 diabetes), episodes of ST depression/elevation, tachycardia, and extrasystoles were more often registered in patients with multivessel lesions of CA (р<0.05), according to HM; the content of CRP in blood serum increased in proportion to the severity of the course of the disease, which depended on the number of affected CA.Conclusions. The nature and severity of the course of CHD correlate with comorbid pathology and the number of CAs affected by atherosclerosis. In the case of multivessel damage, according to the data of clinical, functional and laboratory research, an aggressive progression of cardiac pathology was noted.
HATE SPEECH ON SOCIAL MEDIA: INDONESIAN NETIZENS’ HATE COMMENTS OF PRESIDENTIAL TALK SHOWS ON YOUTUBE
Authors: Tahir Ismail , Ramadhan Muhammad Gana Fajar
Published: April 2024

Hate comments on digital platforms, particularly social media, pose a significant threat to online investigations and present a complex issue for linguistic culture. Previous studies have mainly focused on the analysis of moderation strategies regarding this type of language use on the internet. In contrast, little attention has been given to identifying which hate comments on the internet are considered problematic. The current study investigates the phenomena of Indonesian netizens’ hate comments regarding the presidential election in 2024 on YouTube talk shows uploaded in 2023. By analyzing 315 datasets using Nvivo software, it shows that early warning (43%) is mostly employed by Indonesian netizens, followed by dehumanization and demonization (21%), violence and incitement (19%), and offensive language (17%) respectively. Moreover, it is found that anonymity and personality traits are the factors contributing to hate comments related to the 2024 presidential election. The factors influence Indonesian netizens in early-warning hate comments. The implications of the present study highlight the importance of examining the online behavior and language usage in online communication among Indonesian netizens. This understanding can help in mitigating hate comments on online platforms and in society as a whole.
Ctrl-X, Ctrl-C and Ctrl-V in Veterinary Dermatology: Skin microbiota transplantation as a promising approach for dogs with cutaneous adverse food reactions

Published: April 2024

The probability of influencing the skin microbiome for addressing skin disorders opens a novel aisle of therapy. This study aimed to evaluate the efficacy of skin microbiota transplantation (sMt) for cutaneous adverse food reactions (caFr) in dogs. Ten client-owned dogs with caFr were included in the study. Unenriched heterologous sMt was performed using Nivea Skin Refining Clear-Up Strips (N-cUs). The bacterial microbiota of skin samples was analysed by next-generation sequencing of the 16S rRNA gene. Other relevant biomarkers were involved in VAS (visual analogue scale of pruritus score), CADESI-04 (canine atopic dermatitis extent and severity index) and epidermal corneometric analysis. Increased Faecalibacterium (0 to 1.9 %), Peptoclostridium (5.49 % to 9.11 %) and Collinsella (0.65 % to 8.91 %), and decreased Fusobacterium (19.16 % to 9.06 %), Porphyromona (8.75 % to 0.13 %), Streptococcus (1.63 % to 0.14 %) and Staphylococcus (1.09 % to 0.49 %) was evidenced before and after sMt, respectively. Treatment with sMt effectively controlled clinical signs and drastically reduced median VAS pruritus (6.5 vs. 2) and CADESI-04 scores (74.50±22.62 to 19.30±11.30) (p<0,001). In addition, skin pH and hydration values were improved (p<0,001) after sMt. The heterologous and unenriched sMt with N-cUs could be responsible for the clinical recovery observed in this study.
O construtivismo no programa de formação de professores alfabetizadores
Authors: Ramos Géssica Priscila
Published: April 2024

A análise proposta neste artigo pretende iniciar uma discussão sobre os significados, as estratégias pedagógicas e os objetivos político-econômicos que embasam a defesa oficial do construtivismo na política educacional brasileira após 1995. Para tanto, foca-se o Programa de Formação de Professores Alfabetizadores, criado pelo Ministério da Educação em 2000, e constata-se que: 1) o construtivismo é veiculado neste programa como um novo e superior modelo educacional, adequado para a sociedade atual; 2) variadas estratégias são utilizadas para convencer o professor cursista a assumir o construtivismo em sua prática pedagógica; 3) a concepção construtivista defendida oficialmente, por sua natureza pedagógica flexível, mostra-se coerente ao princípio da racionalização de verbas públicas presente na Reforma do Estado Brasileiro dos anos 1990 ao possibilitar a minimização de mecanismos custosos como reprovação, evasão e fracasso escolar.

Produção textual no ensino fundamental
Authors: Cunha Alessandra Marques da , Garcia Stella de Lourdes , Reyes Claudia Raimundo
Published: April 2024

O presente artigo apresenta uma pesquisa realizada sobre a prática de produção textual nos anos iniciais do Ensino Fundamental. Os gêneros discursivos têm sido apresentados aos professores como objeto de ensino da língua, no entanto, não têm sido acompanhado de reflexões suficientes que possam garantir a formação de escritores competentes. Diante deste contexto, propôs-se um trabalho junto às professoras de uma escola da rede municipal de educação da cidade de São Carlos, estado de São Paulo, no qual se enfatizou o estudo, a reflexão sobre a prática e o desenvolvimento de uma sequência didática para o ensino de um gênero discursivo de texto, tal como proposto pelos pesquisadores do Grupo de Genebra. A metodologia utilizada para a coleta e análise dos dados foi colaborativa dialógica, e os resultados indicaram uma alteração significativa nas práticas pedagógicas e também uma melhora na produção textual dos educandos.
Desindustrialização e salvaguarda do patrimônio industrial: problema ou oportunidade?
Authors: Cordeiro José Manuel Lopes
Published: April 2024

O fenômeno de desindustrialização com que atualmente várias sociedades se defrontam oferece boas possibilidades para fazer face aos problemas causados por essa situação, principalmente com base na salvaguarda e valorização do patrimônio industrial. Embora não seja fácil, sobretudo quando se trata de antigas zonas industriais urbanas ou regiões industriais em declínio, é possível inverter essa situação por meio de estratégias adequadas, que contemplem a reutilização do patrimônio industrial, o qual pode vir a ser usado para múltiplos fins, sejam de natureza cultural, serviços ou habitação. Com base em vários exemplos de reutilização desse tipo de patrimônio - na Espanha, Reino Unido e Alemanha -, são analisados os problemas e questões colocados por cada um deles, tendo em atenção a adoção da estratégia mais adequada para alcançar os objetivos propostos.
Planejando o território: a cidade como categoria social nos anos de 1950
Authors: Ospina Adriana Marcela Sánchez
Published: April 2024

Este artigo aborda a pesquisa realizada por padre Lebret na Colômbia nos anos 1950. Mais especificamente, elabora um quadro reflexivo referente tanto à forma de elaboração da pesquisa, seus resultados, como sua repercussão no cenário político e acadêmico colombiano. Se tem como hipótese que a instabilidade do cenário político no período impediu uma ampla divulgação e implementação das considerações apontadas nos estudos de Lebret à este País. Reconhecendo ser de grande importância os estudos e cursos desenvolvidos por Lebret, que tiveram a cidade latino-americana como objeto de conhecimento, e considerando sua realidade e sua categoria social - ideia inserida na Escola de Humanismo - entende-se que suas ideias ainda são relevantes para a discussão da prática urbanística atual. Desta forma, o artigo divide-se em três partes: uma reflexão sobre o contexto político colombiano no período, a metodologia e pesquisa usada por Lebret dentro deste contexto e por fim, os resultados e sua aplicação.
A rua e a sociedade capsular
Authors: Schvarsberg Gabriel
Published: April 2024

O presente artigo aborda duas experiências urbanas que atualmente disputam espaço no território físico e existencial das cidades brasileiras: a experiência da rua e a experiência capsular, pensada a partir do conceito de “civilização capsular”, proposto pelo filósofo belga Lieven de Cauter. Essas experiências, entretanto, apresentam-se menos como polaridades antagônicas do que superpostas, embaralhadas em variações de intensidades a depender de como cada sujeito urbano elabora seu modo de vida em suas trajetórias cotidianas, sobretudo nos modos como se sujeita aos padrões ditados pelos paradigmas financeiros ou escapa de suas determinações. Como pano de fundo, há a intenção de que o mergulho nesses paradoxos possa contribuir também para a construção de ferramentas críticas e políticas alternativas aos processos hegemônicos de produção do espaço urbano.
Within-tree distribution and seasonal dynamics of Eutetranychus banksi and Euseius stipulatus (Acari: Tetranychidae, Phytoseiidae) on citrus: Implications for the biological control of the pest
Authors: López-Olmos Sergio , Ferragut Francisco
Published: April 2024

The Texas citrus mite, Eutetranychus banksi (McGregor) (Acari: Tetranychidae), is a citrus pest widely distributed throughout the Americas and recently introduced in Spain. In this study we studied the within-tree distribution of E. banksi and the predatory phytoseiid mites, identify the phytoseiid species associated with the pest, and describe the seasonal trends to analyse the predator’s behaviour in response to the increase in pest density, allowing evaluation of biological control possibilities. The Texas citrus mite was mainly found on the adaxial (upper) side of leaves from the current year's shoots located at the periphery of the tree canopy, whereas phytoseiids prefer the abaxial (lower) side of leaves inside the tree canopy. The spider mite preferred to feed on leaves rather than fruits, whereas phytoseiids use both substrates equally. Eutetranychus banksi showed a single population peak in late summer-early autumn, while phytoseiids showed two peaks, a main spring peak and a second less abundant in autumn. The seasonal dynamics of E. banksi and phytoseiids on fruits occurred in parallel to those recorded on leaves. Euseius stipulatus (Athias-Henriot) was the most frequent and abundant phytoseiid species, apparently displacing other predatory mites. In autumn, when E. banksi reached high densities, phytoseiids moved from the leaf abaxial sides inside the tree canopy to the adaxial sides on the periphery and to the fruits, to feed on E. banksi. In addition, a change in phytoseiid colouration from white to reddish-brown was observed. Both, the number of red phytoseiids and their leaf occupation increased significantly in response to the prey population growth, which was indirect evidence of their contribution to the biological pest control. However, the low predator:prey ratios observed cannot avoid the pest population growth.
Microvasculature of the suspensory ligament of the equine hind limb
Authors: Williams Megan R. , Crisman Evan , Taylor Brianne M.
Published: April 2024

OBJECTIVE

To describe the microvascular anatomy of the equine hind limb suspensory ligament.

ANIMALS

18 hind limbs harvested from 9 adult horses euthanized for reasons unrelated to lameness.

METHODS

A catheter was placed in the transected cranial tibial artery at the level of the mid-distal tibia for each hind limb and used to inject 120 to 150 mL of contrast medium (2 limbs) to identify principal vasculature using contrast-enhanced CT or India ink (11 limbs) to identify microvasculature using the Spalteholz tissue-clearing technique. Routine histologic evaluation was performed on transverse sections from 4 hind limbs.

RESULTS

The hind limb suspensory ligament is principally supplied by branches of the medial and lateral plantar metatarsal arteries and, to a lesser extent, the medial and lateral plantar arteries as well as the associated proximal and distal deep plantar arches. A uniformly distributed intraligamentous microvascular supply was observed without relative deficiencies in vascularity between the proximal, midbody, and distal regions. Histologic examination supported these findings, demonstrating a network of connective tissue surrounding and entering the suspensory ligament containing cross-sections of branches of the principal vasculature.

CLINICAL RELEVANCE

The equine hind limb suspensory ligament has a uniformly distributed and abundant microvascular supply throughout its length, with no evidence of relative deficiency of vascular supply in any region. A region of hypovascularity does not appear to be a viable explanation for the high rate of injury to and commonality of lameness associated with the proximal hind suspensory ligament in horses.
