Известно, что в строгой постановке задача нестационарного конвективного теплообмена должна формулироваться и решаться как сопряженная задача с граничными условиями IV рода. Такая постановка предполагает решение внешней гидродинамической задачи и сопряжение ее результатов с решением внутренней задач теплопроводности.
В приближении «бегущей волны» авторами определены предельные значения температуры, при которой происходят термические повреждения (микротрещины – «паутина») теплообменных поверхностей двигателя внутреннего сгорания.
В статье утверждается, что при t = 1200 . . .1800 с температура днища поршня достигает предельного для данного металла значения 750 К, что повышает риск его термического повреждения. При форс-мажорных обстоятельствах (аварийном нагружении двигателя или его перегрузках при плавании во льдах) необходимо использовать съемные днища поршней из жаропрочной стали.
Ключевые слова: температура, «бегущая волна», термическое повреждение.

Luces y sombras de la Lista del Patrimonio Mundial. Reflexiones a propósito del cincuenta aniversario de la Convención del Patrimonio Mundial
Authors: Menéndez Montero Vanesa
Published: July 2022

Medio siglo de aplicación de la Convención del Patrimonio Mundial ha dado lugar a la configuración de una Lista que, aunque aspira a la mayor representatividad posible, se ha quedado corta en el reconocimiento de cierto patrimonio cultural y natural, especialmente de aquél situado en el Sur Global. Las causas (inintencionadas) de esta falta de reconocimiento son múltiples, aunque cabe destacar la disparidad entre la configuración del entramado institucional de la Convención, que refleja la práctica administrativa de los países europeos, y las recientes y, en ocasiones, deficientes instituciones de los países en vías de desarrollo. Si bien es cierto que la inscripción de ciertos sitios en la Lista del Patrimonio Mundial ha generado grandes beneficios, también ha desencadenado consecuencias nefastas para las comunidades locales que deben de soportar los costes económicos, sociales y culturales de un creciente turismo de masas homogeneizador y poco sostenible. Todo ello ha servido como caldo de cultivo para el surgimiento de sentimientos de rechazo hacia lo foráneo y de resentimiento hacia el propio sistema de patrimonio mundial de la UNESCO, poniendo así en riesgo la protección del mismo patrimonio cultural y/o natural. Como solución, la doctrina ha propuesto la inclusión de estas comunidades en los procesos de toma de decisiones relativos al patrimonio mundial, aunque la obligatoriedad de esta medida aún dista mucho de ser una realidad.

Hydration and hypoxic-occlusion therapy (gel-wrap treatment) for hypertrophic scars and keloids
Authors: Yamada Haruyoshi
Published: July 2022

Keloids and hypertrophic scars are pathological fibroproliferative disorders characterized by excessive collagen deposition. The affected skin becomes raised and thickened, forming firm pink or red plaques. Common causes include trauma, burn, and surgery. Multiple studies on keloids and hypertrophic scars have been reported previously, leading to the development of various therapeutic approaches for them, most of which remain clinically unsatisfactory. In this study, three patients underwent the gel-wrap treatment: the gel (manufactured by ITO Co Ltd.) was applied to the lesion and the affected skin was wrapped with a polyvinylidene chloride film (Saran Wrap; Asahi Kasei Corporation). Satisfactory results were noted in all three cases. The gel-wrap treatment is more convenient and inexpensive than existing therapeutic approaches. Furthermore, reducing thymic stromal lymphopoietin seems crucial for the treatment of keloids and hypertrophic scars.

Background: Facial aging causes a devastating physical and mental impact on quality of life. Objective: To evaluate the efficacy and safety of autologous platelet concentrate (APC) in the treatment of cutaneous photoaging (SCF). Method: Between March 1, 2017 and March 31, 2021, at the “Hermanos Ameijeiras” hospital, a randomized, single-center, double-blind and controlled clinical trial was carried out in 164 patients with ECF. A group treated with CPA was compared to another treated with fresh autologous plasma (AFP). The treatment was applied monthly for 1 year. Results: Three months after the end of the treatment, there were significant differences between the patients treated with CPA compared to those treated with PFA in terms of the improvement in the degree of photodamage and the degree of satisfaction (p <0.001). All adverse events were of mild intensity, did not imply changes before the intervention and were completely resolved. Conclusions: The autologous platelet concentrate proved to be effective and safe to reduce the signs of skin aging, associated with a high degree of patient satisfaction.

Authors: Santos Cintia Marques dos , Braga Amabilym Leal de Carvalho , Santos Jordan Maciel dos , Oliveira Milena Borges de , Madureira Moisés Teles
Published: July 2022

A energia é um assunto de importância estratégica para os países de todo o mundo. A economia mundial está fortemente atrelada à indústria do petróleo como fonte de produção de energia. No entanto, iniciativas ambiciosas já foram deflagradas no sentido de tirar o mundo da dependência preponderante do petróleo. Tais iniciativas são motivadas por diversos fatores: crescimento populacional e impactos ambientais se constituem nos de maiores influência. O presente trabalho tem como objetivo abordar, na forma de um panorama geral, um retrato situacional das questões envolvidas com a problemática das mudanças climáticas e da transição energética. Como resultado, verifica-se que são presentes as preocupações e tentativas de se mitigar ou até anular os efeitos sobre o clima global devido as atividades industriais. O Brasil, não estando isento a essas problemáticas, já se mostra com uma postura de alinhamento político e ajustamento de condutas no sentido de atender metas globais de redução de impactos ambientais, principalmente redução de emissão de gases de efeito estufa.

A infecção do trato urinário (ITU) e a colonização do trato urinário são extremamente frequentes, ocorrendo em todas as faixas etárias. O uso indiscriminado de antibióticos ambulatoriamente, e também no ambiente nosocomial, é um fator de risco importante para o surgimento e disseminação de resistência microbiana. O alto nível de resistência múltipla apresenta um risco potencial para a saúde pública e pode dificultar o tratamento de doenças. Analisamos o perfil de resistência bacteriana de uroculturas, bem como dados sobre as infecções urinárias e colonizações do trato urinário nos pacientes atendidos na Unidade de Terapia Intensiva (UTI) da Fundação Hospitalar São Lucas, Município de Cascavel/PR. Trata-se de um estudo transversal, retrospectivo, realizado através de prontuários de pacientes internados em unidade de terapia intensiva, no período de janeiro de 2019 a janeiro de 2021. Analisamos dados sobre infecção de trato urinário e colonização de trato urinário, bem como perfil de resistência microbiana e características clínicas dos respectivos pacientes. Obtivemos um total de 87 pacientes que possuíram urocultura positiva, sendo 66 colonizações de trato urinário, 9 classificadas como ITU não associada a cateter, 10 como ITU associada a cateter e 2 como ITU relacionada a assistência a saúde. Encontramos 15 tipos de microorganismos e diferentes resistências aos antibióticos. Comparamos com outros 4 trabalhos, para obter a diferença nos valores de resistência em diferentes localidades. As bactérias mais encontradas no estudo foram Escherichia coli, Klebsiella sp. e Pseudomonas aeruginosa. Pseudomonas aeruginosa teve os maiores percentuais de isolados multirresistentes.

Published: July 2022

O suicídio é um fenômeno mundial, em 2015 cerca de 800.000 suicídios foram documentados em todo o mundo, responsáveis por 1,4% das mortes prematuras. A maioria, em todo o mundo, está relacionada a doenças psiquiátricas com números de pelo menos 10 vezes mais altos do que na população em geral. O comportamento suicida é influenciado por vários fatores precipitantes e compreende-los é fundamental para o aprimoramento das medidas preventivas que visam diminuir a carga e a mortalidade da doença. No Brasil as taxas de suicídio podem chegar a 6,5 mortes a cada 100 mil habitantes. Estima-se que cada suicídio afete um grande círculo de pessoas envolvidas e que poderão necessitar de serviços médicos ou apoio após a exposição. O presente estudo abordou a prevalência das tentativas de suicídio da Unidade de Pronto Atendimento - UPA Veneza, um serviço de urgência/emergência do município de Cascavel – Paraná, no período de junho de 2019 a junho de 2020. Com o objetivo de analisar a ocorrência dos casos de tentativa de suicídio procedentes na UPA Veneza, comparando-os com os índices descritos no cenário nacional atual, foram averiguados 130 prontuários de pacientes que tiveram seu diagnóstico como tentativa de suicídio.
Ocean warming and multiple source populations increase the threat of an invasive bryozoan to kelp beds in the northwest Atlantic Ocean
Authors: Pratt C , Denley D , Metaxas A
Published: July 2022

Climate change is expected to create more favourable climatic conditions for many invasive species, increasing their abundance and range. One such invasive species is Membranipora membranacea, an epiphytic bryozoan causing defoliation of kelp beds in the northwest Atlantic Ocean (NWA). The impact of M. membranacea is directly linked to its abundance, which is anticipated to increase due to climate change. Additionally, further range expansion may threaten Arctic kelp beds in the future. We constructed a species distribution model (SDM) to predict the abundance of M. membranacea in the NWA under present and future climate scenarios. We also assessed the effect of a possible additional invasion of M. membranacea from populations in Norway. The projected future abundance distribution of M. membranacea in the NWA differed substantially depending on the future climate scenario employed, but the bryozoan was predicted to occur in the Arctic at low abundances regardless of the scenario. However, we also found that populations of M. membranacea in Norway achieve much higher abundances at lower temperatures than NWA populations and could pose a dire threat to kelp beds in the NWA and southern Canadian Arctic if introduced in these regions. Although the SDMs performed well under internal validation, estimating the impact of M. membranacea is complicated by the context-dependent response of kelp communities to coverage by the bryozoan. Nonetheless, this study provides valuable predictions of the response of an ecologically significant invasive species to climate change with findings of broader relevance to the study of other invasive organisms.
ENTREPRENEURSHIP-INSIGHTED VILLAGE-OWNED ENTERPRISE (BUMDes) LEADERSHIP CONCEPT IN REALIZING A COMPETITIVE AND SUSTAINABLE DEVELOPMENT STRATEGY OF THE SINARANCANG TOURISM VILLAGE
Authors: Qira'ati Muhfidlatul
Published: July 2022

Sinarancang Village as the Setu Patok area has the potential for natural tourism and potential open public spaces. Sinarancang Village has a strategic location because it is close to Setu Patok. The potential for natural and river tourism along with the community mortar home industry are some of the attractions that motivate BUMDes Rancang Jaya to develop it as a tourist village. BUMDes Rancang Jaya, as a newly established company owned by the Village of Sinarancang, has a vision of creating a tourism village called Sinarancang, which is able to attract Cirebon tourists to visit. BUMDes Rancang jaya has been observing and studying other BUMDes that have succeeded in developing tourist villages and attracting tourists. They see the motivation of tourists in visiting Sinarancang Village because of its location near Setu Patok with beautiful views. This is one of the reasons why tourism needs to be developed for developing villages as a means of capturing new opportunities in meeting community needs. The purpose of this study is to identify entrepreneurial characteristics that are applied in business development carried out by BUMDes and to describe the concept of BUMDes leadership which has entrepreneurial characteristics in realizing the development strategy of the Sinarancang tourism village. This study used a qualitative descriptive method with secondary data analysis in the form of village policy documents and primary data analysis from observations and interviews. Regional leadership needs to demonstrate entrepreneurial characteristics. In this case, the leadership of BUMDes Rancang Jaya has shown the beginnings of entrepreneurial characteristics according to Schumpeter (1934) and Kirzner (1973), namely believing in change and making innovations in institutional settings. To realize the development strategy of the Sinarancang Tourism Village, it requires BUMDes leadership with entrepreneurial insight, namely those that fulfill 6 entrepreneurial characteristics in the context of regional development (Stimson, 2009), so that the motivation of entrepreneurship in the context of regional development is realized, namely creating individual economic benefits that occur from cultural enhancement or the regional economic context (business climate) and social welfare as well as community benefits stemming from spillover and institutional effects.Keywords: Sinarancang, Tourism Village, BUMDes, Regional Leadership, Entrepreneurship

Published: July 2022

The shift to online learning milieu due to the Covid-19 pandemic has brought some impact in the practices or teaching learning including the nature of writing corrective feedback (WCF) that should also be migrated to online platforms. Although much research has been conducted on the effectiveness of WCF, less has explored student and teacher preferences and perceptions of online corrective feedback through various platforms in student thesis writing in response to this abrupt learning transformation. Lensing from a case study, we recruited two English teachers and fifteen learners non-randomly with a purposive sampling technique. This study used closed-ended questionnaires and semi-structured interviews. In analyzing the data, the researchers used the formulation of Sudijono (2006) for a closed-ended questionnaire and adapted the steps formulated by Creswell (2003) to analysis the interview data. The result showed that there were differences in preferences and perceptions between teachers and learners regarding the use of different types of WCF: direct and indirect feedback. The teachers prefer to use both types of feedback: direct and indirect feedback. Meanwhile, learners preferred direct corrective feedback. Thus, some pedagogical contribution is also discussed, accordingly.

The work is devoted to the study of the photosynthetic activity of the leaves of some evergreen trees and shrubs introduced on the Absheron Peninsula. Using the LI-6400XT Portable Photosynthesis System RC-P60, 2021 (made in China), the molar amount of CO2 and water, the temperature index inside and in the external environment of the leaf, photosynthetic activity and transpiration rate, relative humidity, and other parameters were determined green leaf. It has been established that there is a direct correlation between the absorbed carbon dioxide and the amount of evaporating water emitted and the presence of the relative humidity of the leaf, which is an indicator of the activity of photosynthesis. The accumulated organic compounds are a source of potential energy during intracellular oxidation. The presence of a dense epidermis of eucalyptus and oleander leaves ensures the economical use of water molecules during transpiration.

Changes in chlorophyll a and chlorophyll b contents due to some biotic and abiotic factors have been found in the studied lentil varieties and specimens. In the branching stage, the chlorophyll a content ranged between 4.039 and 7.737 mg/g dry mass. During the whole vegetation period, maximum and minimum values 7.737 and 4.242 mg/g, respectively of the Chl a content was observed in the LIEN-LS-17(34) specimen. In the flowering period, the Chl a content changed in the range of 5.464–8.432 mg/g. The LICTN-17 (3) specimen was distinguished by the high amount 8.432 mg/g of Chl a. In the branching phase of the vegetation period, the Chl b content ranged between 1.526 and 5.672 mg/g. Whereas, in the flowering phase the Chl b content changed in the range of 1.665–2.612 mg/g. The maximum value of the Chl b content in the LICTN-17(3) specimen was equal to 2.612 mg/g. During the bean formation period, the Chl a content increased in some specimens and decreased in others. Thus, in the lentil varieties, the Chl b content reached maximum values 1.745–5.997 mg/g in the flowering and bean formation periods. During the grain filling period the Chl b content in lentil varieties and specimens decreased and amounted to 1.205–3.895 mg/g. The maximum carotenoid content was found during the flowering and bean formation periods in leaves of lentil varieties and specimens. The carotenoid content ranged between 1.88 mg/g and 3.07 mg/g in the leaves of the studied lentil varieties and specimens. The research revealed the highest value of the chlorophyll content in the flowering and bean formation phases. Our research has shown that there is a certain relationship between the chlorophyll content and photosynthetic productivity.

Fascioliasis in Sheep in the Julfa District (Nakhchivan, Azerbaijan)
Authors: Ganbarov H.
Published: July 2022

The article reflects the biological and ecological features of Fasciola parasitizing in sheep, reared in the territory of the Julfa district (Nakhchivan, Azerbaijan), and preventive measures against them. As a result of the research conducted, it was found out that 2 types of Fasciola are parasitized on the territory of the Julfa district: Fasciola hepatica Linnaeus (common liver fluke) and F. gigantica Cobbold. From the analysis of helminthoovoscopic examinations of internal organs (liver and gallbladder) of 242 sheep studied, it turned out that both the intensity (4.4–22.2 units) and the extensiveness of invasion (39.2%) were sufficient. Depending on the climatic zone of the area, the extensiveness and intensity of invasion prevail in several low-lying zones. However, the invasion was not detected in organs belonging to 41 head of sheep taken from mountainous and foothill areas. Here we can come to the conclusion that the lack of suitable temperature and humidity for the development of eggs in areas where invasion was not detected, led here to a break in the chain of Fasciola development.

The image fusion algorithm has great application value in the domain of computer vision, which makes the fused image have a more comprehensive and clearer description of the scene, and is beneficial to human eye recognition and automatic mechanical detection. In recent years, image fusion algorithms have achieved great success in different domains. However, it still has huge challenges in terms of the generalization of multi-modal image fusion. In reaction to this problem, this paper proposes a general image fusion framework based on an improved convolutional neural network. Firstly, the feature information of the input image is captured by the multiple feature extraction layers, and then multiple feature maps are stacked along the number of channels to acquire the feature fusion map. Finally, feature maps, which are derived from multiple feature extraction layers, are stacked in high dimensions by skip connection and convolution filtering for reconstruction to produce the final result. In this paper, multi-modal images are gained from multiple datasets to produce a large sample space to adequately train the network. Compared with the existing convolutional neural networks and traditional fusion algorithms, the proposed model not only has generality and stability but also has some strengths in subjective visualization and objective evaluation, while the average running time is at least 94% faster than the reference algorithm based on neural network.

Published: July 2022

The extracellular human endo-6-O-sulfatases (Sulf-1 and Sulf-2) are responsible for the endolytic cleavage of the 6-sulfate groups from the internal D-glucosamine residues in the highly sulfated subdomains of heparan sulfate proteoglycans. A trisaccharide sulfate, IdoA2OS-GlcNS6S-IdoA2OS, was identified as the minimal size of substrate for Sulf-1. In order to study the complex structure with Sulf-1 for developing potential drugs, two trisaccharide analogs, IdoA2OS-GlcNS6OSO2NH2-IdoA2OS-OMe and IdoA2OS-GlcNS6NS-IdoA2OS-OMe, were rationally designed and synthesized as the Sulf-1 inhibitors with IC50 values at 0.27 and 4.6 μM, respectively.
Thermally-stable single-atom catalysts and beyond: A perspective
Authors: Liu Sixu , Li Jiwei , Xiong Haifeng
Published: July 2022

Single-atom catalysis is a research Frontier and has attracted extensive interests in catalysis. Significant progresses have been carried out in the synthesis and characterization of metal single-atom catalysts (SACs). However, the stability and catalytic reactivity of metal SAC at elevated temperatures are not well documented because single atoms sinter at elevated temperatures. Therefore, the development of stable and reactive SAC at high temperatures remains a formidable challenge. In this perspective, we summarize recent efforts on the preparation of the thermally-stable SACs synthesized at elevated temperature via the reverse-Ostwald ripening mechanism, including the approaches of atom trapping and vapor-phase self-assembly. The reducibility of lattice oxygen, the loading upper limit and the location of the metal single atom are discussed, combining experiments with simulations. In addition, we demonstrate that the coordination structure of the metal single atom can be tailored to address the relationship of structure and performances of the metal SAC in reactions. We expect that this perspective can provide some insights to guide the study for the rational design of thermally-stable and active single atom catalysts, which are especially suitable for high-temperature reactions.

Background and Objectives

Use of drug-coated balloon (DCB)-only strategy for revascularization of native large coronary artery lesions is on the rise. The long-term efficacy of this approach for bifurcation and non-bifurcation lesions remains unknown. We aim to assess the long-term clinical outcomes of DCB-only strategy for the treatment of de novo bifurcation and non-bifurcation lesions in large coronary arteries.

Methods

This multicenter, prospective, observational study enrolled 119 patients with de novo coronary lesions in vessels ≥2.75 mm. The primary end point was the rate of clinically driven target lesion failure (TLF), a composite of cardiac death, target vessel myocardial infarction, and clinically driven target lesion revascularization (TLR). Patients were followed up for a median of 2 years.

Results

Of 119 patients with 138 lesions, 66 patients (75 lesions) had bifurcation and 53 patients (63 lesions) had non-bifurcation lesions. Average reference vessel diameter was 3.1 ± 0.3 mm, and there was no difference in bifurcation and non-bifurcation group (3.0 ± 0.3 vs. 3.1 ± 0.3mm; p = 0.27). At 2-year follow-up, the TLF occurred in five (4.2%), TLR in four (3.4%), and target vessel revascularization (TVR) in five (4.2%) cases. The frequency of TLR and TVR was higher in the non-bifurcation group (p = 0.04 and 0.02, respectively), but there were no differences in TLF between the two groups (p = 0.17). The cumulative incidence of TLF (Kaplan–Meier estimates) was also not different in the two groups (log-rank p = 0.11).

Conclusion

DCB-only strategy for de novo lesions in large coronary arteries appears to be safe and effective for both bifurcation and non-bifurcation lesions. Further randomized clinical trials are warranted to confirm the value of DCB-only strategy in de novo bifurcation lesions of large vessels.

The core clock component REV-ERB is essential for heart function. Previous studies show that REV-ERB agonist SR9009 ameliorates heart remodeling in the pressure overload model with transverse aortic constriction (TAC). However, it is unknown whether SR9009 indeed works through cardiac REV-ERB, given that SR9009 might target other proteins and that REV-ERB in non-cardiac tissues might regulate cardiac functions indirectly. To address this question, we generated the REV-ERBα/β cardiac-specific double knockout mice (cDKO). We found that REV-ERB cardiac deficiency leads to profound dilated cardiac myopathy after TAC compared to wild-type (WT) control mice, confirming the critical role of REV-ERB in protecting against pressure overload. Interestingly, the cardioprotective effect of SR9009 against TAC retains in cDKO mice. In addition, SR9009 administered at the time points corresponding to the peak or trough of REV-ERB expression showed similar cardioprotective effects, suggesting the REV-ERB-independent mechanisms in SR9009-mediated post-TAC cardioprotection. These findings highlight that genetic deletion of REV-ERB in cardiomyocytes accelerates adverse cardiac remodeling in response to pressure overload and demonstrated the REV-ERB-independent cardioprotective effect of SR9009 upon pressure overload.
Behaviors of Redox-Sensitive Components in the Volcanic Plume at Masaya Volcano, Nicaragua: H2 Oxidation and CO Preservation in Air

Multi-disciplinary volcanic gas observations, including FTIR, Multi-GAS, and Alkali filter pack, were made at Masaya Volcano, Nicaragua, in January 2018. During the observation period, a lava lake was present, and the majority of the volcanic gases were likely emitted directly from the lava without any hydrothermal alterations. It is expected that the volcanic gas composition reflects the conditions of the magma, exhibiting a high equilibrium temperature. The fractions of the major components showed good consistency with previous studies; however, we found the fraction of the combustible components (such as H2) were lower than expected. The RH [log(H2/H2O)] value was measured to be less than −6, compared to the equilibrium RH value calculated to be around −3 from the iron speciation. The equilibrium calculations suggest oxidation of the volcanic gases by high-temperature mixing with the air once they are emitted from the lava lake, lowering the H2 content of the plume. In contrast to H2, a small amount of CO, another combustible species, was detected and the derived CO2/CO ratio of ca. 1,000 is consistent with the equilibrium magmatic value. This indicates that CO is kinetically inert compared to H2. Our findings suggest that volcanic gases in the Masaya plume do not preserve information from when the gases were originally in equilibrium with the high-temperature surrounding magma.
