Published: August 2021

Real-time process metrics are standard for the majority of fermentation-based industries but have not been widely adopted by the wine industry. In this study, replicate fermentations were conducted with temperature as the main process parameter and assessed via in-line Oxidation Reduction Potential (ORP) probes and at-line profiling of phenolics compounds by UV-Vis spectroscopy. The California and Oregon vineyards used in this study displayed consistent vinification outcomes over five vintages and are representative of sites producing faster- and slower-fermenting musts. The selected sites have been previously characterized by fermentation kinetics, elemental profile, phenolics, and sensory analysis. ORP probes were integrated into individual fermentors to record how ORP changed throughout the fermentation process. The ORP profiles generally followed expected trends with deviations revealing previously undetectable process differences between sites and replicates. Site-specific differences were also observed in phenolic and anthocyanin extraction. Elemental composition was also analyzed for each vineyard, revealing distinctive profiles that correlated with the fermentation kinetics and may influence the redox status of these wines. The rapid ORP responses observed related to winemaking decisions and yeast activity suggest ORP is a useful process parameter that should be tracked in addition to Brix, temperature, and phenolics extraction for monitoring fermentations.

Published: August 2021

Diketopyrrolo[3,4-c]pyrroles (DPP) are high-performance organic optoelectronic materials. They have applications in solar cells, fluorescent probes, bioimaging, photodynamic/photothermal therapy, and in many other areas. This article reports a convenient two-step synthesis of various DPP dyes from Pigment Red 254, an inexpensive commercial pigment. The synthesis includes a Suzuki–Miyaura cross-coupling reaction of a bis(4-chlorophenyl)DPP derivative with aryl and hetaryl boronic acids under mild reaction conditions. The new dyes show large Stokes shifts and high fluorescence quantum yields, important features for their potential use in technical and biological applications.
Modern Applications of 3D Printing: The Case of an Artificial Ear Splint Model
Authors: Argyropoulos Athanasios , Botsaris Pantelis N.
Published: August 2021

Three-dimensional (3D) printing is a leading manufacturing technique in the medical field. The constantly improving quality of 3D printers has revolutionized the approach to new challenges in medicine for a wide range of applications including otoplasty, medical devices, and tissue engineering. The aim of this study is to provide a comprehensive overview of an artificial ear splint model applied to the human auricle for the treatment of stick-out protruding ears. The deformity of stick-out protruding ears remains a significant challenge, where the complex and distinctive shape preservation are key factors. To address this challenge, we have developed a protocol that involves photogrammetry techniques, reverse engineering technologies, a smart prototype design, and 3D printing processes. Specifically, we fabricated a 3D printed ear splint model via fused deposition modelling (FDM) technology by testing two materials, a thermoplastic polyester elastomer material (Z-Flex) and polycaprolactone (PCL 100). Our strategy affords a custom-made and patient-specific artificial ear aligner with mechanical properties that ensures sufficient preservation of the auricular shape by applying a force on the helix and antihelix and enables the ears to pin back to the head.
Effect of Pre-Treatment Conditions on the Activity and Selectivity of Cobalt-Based Catalysts for CO Hydrogenation
Authors: Shiba Nothando C. , Liu Xinying , Hildebrandt Diane , Yao Yali
Published: August 2021

We investigated the effect of pre-treatment conditions on the activity and selectivity of cobalt catalysts for Fischer–Tropsch synthesis (FTS) by varying both the reduction atmosphere and the reduction temperature. Catalysts supported on SiO2, Al2O3, and TiO2, prepared via incipient wetness impregnation, were evaluated, and activation temperatures in the range 250–350 °C were considered. Activation with syngas led to a better product selectivity (low CH4, high selectivity to liquid hydrocarbons, and low paraffin to olefin ratio (P/O)) than the catalysts reduced in H2 at lower activation temperatures. The CoxC species suppressed the hydrogenation reaction, and it is hypothesised that this resulted in the high selectivity of olefins observed for the syngas pre-treated catalysts. On the basis of the experimental results, we postulated that a synergistic effect between Co0 and CoxC promotes the production of the long chain hydrocarbons and suppresses the formation of CH4. In addition, for systems aimed at producing lower olefins, syngas activation is recommended, and for the FTS plants that focus on maximising the production of higher molecular weight products, H2 activation might be considered. These results provide insights for the future FTS catalyst design and for target product-driven operations.

Agricultural labor force, agricultural economy, and farmland use are momentous components of sustainable development in rural areas, as well as essential causes of drastic changes in the urban–rural transformation. This paper studies the spatial–temporal characteristics of the labor–farmland–economy coupling structure from 2000 to 2018 in rural areas of Chongqing using spatial analysis technology. The study has four main results. First and foremost, not only has the average annual rate of the agricultural labor force in Chongqing reduced by 3.73%, but the reduction rates in Jiangbei District, Dadukou District, Nan’an District, Shapingba District, and Yubei District have exceeded 15%. Then, the average annual rate of the agricultural economy has increased by 9.32%, but it has been in a downward trend in Dadukou District, Jiangbei District, and Shapingba Districts. Furthermore, the average annual decline rate of farmland area is 0.34% with larger reduction occurring in the nine of the central urban districts, Chengkou County and Wushan County. Ultimately, there have been 33 districts and counties with the temporal–spatial characteristics of labor–farmland–economy coupling above primary coordination, which includes 16 districts and counties reaching a high coordination. This provides theoretical and methodical supports for the coordinated development of human and land industries in different regions.

Objetivo: Abordar o manejo do câncer colorretal, discutindo não só as indicações dos principais procedimentos terapêuticos do CCR, mas também quando combiná-las. Metodologia: Uma revisão integrativa desenvolvida a partir da seleção de ensaios clínicos publicados entre os anos de 2016 e 2021, disponíveis na base de dados do Pubmed. Os descritores utilizados foram: Cancer, colorectal OR Cancers, colorectal OR Carcinoma, colorectal OR Carcinomas, colorectal AND Chemotherapy AND Resection. Resultados: Ainda que alguns estudos demonstraram que a quimioterapia com FOLFIRIX foi favorável para a ressecção do câncer colorretal, outros atestam seu efeito negativo na ressecção de tumores locais e metástases. O uso de probióticos está associado a uma redução significativa das complicações da quimioterapia. A quimioterapia hipertérmica intraperitoneal adjuvante (HIPEC) associada a quimioterapia sistêmica demonstrou não superioridade em relação a apenas a quimioterapia. A infusão intra-hepática não contribuiu para a melhora da sobrevida global. A fluorescência foi observada em todos pacientes submetidos à técnica de cirurgia guiada. Conclusão: Ainda existem divergências com relação ao uso da terapia adjuvante, diferente da neoadjuvante que apresentou eficácia na maioria dos casos. Sugere-se a realização de novos estudos para sanar as divergências e observar a longo prazo os resultados, principalmente, das novas terapias.

Published: August 2021

Pediatric meningiomas are rare and account for only 2.2% of CNS tumors. In this age group, they are more frequently located in atypical sites, such as, mainly, the ventricular system, with a frequency of 8.8 to 13.6%. Adding this to the fact that the angiomatous subtype constitutes only 2.1% of all meningiomas, the rarity of the case reported here i s corroborated. We report a 17-year-old female patient diagnosed with intraventricular angiomatous meningioma; she underwent surgical resection of the tumor in the body and frontal horn of the right lateral ventricle, and there was no neurological sequela. With a follow-up of 4 years, there was no recurrence and the patient had clinical stability. Intraventricular tumors usually have slow growth and reach considerable size until they cause symptoms and then are diagnosed. In addition, the tumor’s deep location and proximity to eloquent areas make such tumors an neurosurgical challenge. The angiomatous subtype, due to the presence of hypervascularization (consisting of more than 50% of vascular components), may, in some cases, hinder surgical resection as well as be erroneously diagnosed. However, surgical treatment aimed at total resection of the lesion remains the conduct of choice in the case reported here, especially in patients in the first two decades of life, in which the use of radiation is avoided. Specifically when it comes to the surgery, we chose a transcallosal approach that allows a good transoperative visualization of the lesion when located in the body and frontal horn of the lateral ventricle.

Authors: Nikiforov A , Smyk S
Published: August 2021

Crisis management, or, in other words, management in the "strong" maneuver mode, refers to the most complex types of organizational management. The large dimensionality of decision-making tasks coupled with a shortage of time put forward an urgent need to automate crisis management procedures. However, such features of crisis management as: weak structuring of the tasks to be solved due to their uniqueness, uncertainty of conditions, volatility of goals (aspects) of management -serve as an obstacle to automation. The ontological approach offers a number of advantages with solutions and problems of crisis management automation. Applying the activity ontology to organizational multi-aspect management, one expands significantly the application field of formalized methods. It makes alternatives more detailed.
