Estafilectomia em um cão da raça West Highland White Terrier: Relato de caso

Objetivou-se relatar o caso de um canino, macho, com idade aproximada de sete anos, da raça West Highland White Terrier, apresentando sinais clínicos de disfagia, intolerância ao exercício, engasgos recorrentes e dispneia sendo observados a aproximadamente cinco anos, diagnosticado com prolongamento de palato mole. Os exames complementares de diagnóstico utilizados foram radiografia de tórax e tomografia computadorizada da região crânio cervical revelando hipertrofia de palato mole e linfoadenomegalia cervical. O alongamento do palato mole é uma das anomalias que compõe a síndrome do braquicefálico, podendo ocorrer em qualquer raça, porém pouco relatado em animais que não sejam braquicefálicos. Mediante resultados foi constatado a necessidade de tratamento cirúrgico para ressecção parcial do palato mole, sendo considerado o método mais eficaz para tal anomalia. Foram solicitados exames hematológicos, bioquímicos e avaliação cardiológica como pré-operatório. A Estafilectomia é o nome do procedimento cirúrgico de correção do palato mole alongado, o qual foi realizado com o uso de bisturi ultrassônico. Apesar de ser um aparelho ainda pouco utilizado e reconhecido, seu uso reduz o tempo de trans e pós-operatório, elevando a qualidade de vida do animal já no pós-operatório imediato. Após dez dias de pós-operatório com protocolo de antibiótico, anti-inflamatório, analgésico, protetor gástrico, antivaricoso, alimentação liquida/pastosa sendo pelo menos uma das refeições oferecida gelada por cinco dias, os tutores relataram que o animal começou a apresentar melhora já nas primeiras 24 horas após o procedimento. Conclui-se que a Estafilectomia é um procedimento cirúrgico ainda pouco comum na clínica cirúrgica de pequenos animais, mas de extrema relevância, já que extingue a sintomatologia do paciente promovendo qualidade de vida ao mesmo.
CNN-based People Detection in Voxel Space using Intensity Measurements and Point Cluster Flattening

In this paper real-time people detection is demonstrated in a relatively large indoor industrial robot cell as well as in an outdoor environment. Six depth sensors mounted at the ceiling are used to generate a merged point cloud of the cell. The merged point cloud is segmented into clusters and ﬂattened into gray-scale 2D images in the xy and xz planes. These images are then used as input to a classiﬁer based on convolutional neural networks (CNNs). The ﬁnal output is the 3D position ( x, y, z ) and bounding box representing the human. The system is able to detect and track multiple humans in real-time, both indoors and outdoors. The positional accuracy of the proposed method has been veriﬁed against several ground truth positions, and was found to be within the point-cloud voxel-size used, i.e. 0 . 04 m. Tests on outdoor datasets yielded a detection recall of 76 . 9 % and an F1 score of 0 . 87.
Highly selective and sensitive biosensing of dopamine based on glutathione coated silver nanoclusters enhanced fluorescence

This study describes an ultrasensitive and highly selective dopamine (DA) assay that makes use of glutathione protected silver nanoclusters (GSH-AgNCs) acting as a nanoprobe. The GSH-AgNCs exhibit red fluorescence (with excitation/emission peaks at 490/645 nm), which increases on addition of DA, probably due to the hydrogen bonding interaction of the carboxyl groups of GSH-AgNCs and the amino groups of DA. The response is linear in the 20 × 10−9 mol dm−3 to 220 × 10−9 mol dm−3 DA concentration range, and the lowest limit of detection is 0.35 × 10−9 mol dm−3 (at an S/N ratio of 3). Potential interferents including uric acid, ascorbic acid, common metal ions, anions and some biologically relevant chemicals do not have an effect even in 100-fold higher concentrations. Furthermore, the present analytical assay was effectively utilized for the quantification of DA in spiked human urine samples.

Phase transformation of goethite into magnetite by reducing with carbohydrates

Phase transformations of synthetic goethite and goethite ore from Kryvyi Rih region by reducing with different carbohydrates (starch, glucose, fructose, sucrose and ascorbic acid) were investigated by thermomagnetic analysis. Thermomagnetic analysis was carried-out using laboratory device that allows automatic registration of sample magnetization with the temperature (the rate of sample heating/cooling was 65-80°/min). The reduction reaction of synthetic goethite for all carbohydrates starts at the temperature of ~250°C while reduction of goethite ore for all carbohydrates starts at the temperature of ~450°C. We could relate this increasing of reduction start temperature with shielding effect of admixtures in the ore. Reduction of synthetic goethite at this temperature range leads to formation of magnetic phase with saturation magnetisation ~70 A*m/kg. At the same time, reduction of goethite ore leads to formation of magnetic phase with saturation magnetisation ~25 A*m/kg. One could attribute this decreased value of saturation magnetisation to the presence of other minerals (quartz, etc.) in the ore. It was shown by X-Ray Diffraction method that goethite completely transforms into magnetite under heating with different carbohydrates up to 650°C. All carbohydrates reduce goethite to magnetite.
Effect of novel cryogenic treatment in the corrosion behaviour, microstructure analysis and electrochemical properties of Al 6101 closed-cell foam

ABSTRACT The corrosion behaviour of the closed-cell aluminium foam made of Al 6101 alloy in different heat regimes such as heat treatment (HT), cryogenic treatment (CT) and cryogenic heat treatment (CHT) are investigated in this research work. The Electrochemical Impedance Spectroscopy (EIS) and DC polarisation are the techniques employed in this research work. The microstructure, surface morphology and composition of the treated foam samples are evaluated using a high-resolution Scanning Electron Microscope (SEM) and Energy Dispersive Analysis of X-rays (EDAX). The polarisation and electrochemical impedance measurements of the CT and HT foam samples reveal appealing results in the corrosion resistance when comparing with untreated foam sample. From the SEM images, it is evident that the deep cryogenic treatment changes the morphology of Al 6101 foam and the formation of the Guinier-Preston (GP) zone increases the density of dislocation.
IMPLEMENTATION OF TOTAL QUALITY MANAGEMENT COMPONENTS IN LIBYAN IRON & STEEL COMPANY “LISCO”

Quality is usually considered as a combination of characteristics of an object, which testifies to its ability to satisfy identified needs, the author's proposed definition of the concept of quality management for a company as the system of management, aimed at planning, implementation, improvement and quality control of the company in accordance with the established policy and objectives of the company, with the participation of all its units. Customer satisfaction depends on the fact that the company has an effective quality management system. Thus, an integrated quality management system is created and implemented as a means of ensuring the implementation of specific policies and the achievement of quality objectives set by top management. Therefore, special attention is paid to the formation and documentation of the company's management policy on the quality of products provided to consumers. Manufacturing companies in Libya face difficulties to introduce Total Quality Management system. The original result indicates that lack of skilled labor, employee culture resistance to change, and lack of management commitment and leadership are correlated with a variety of factors that hinder advancement. A lack of benchmarking and employee resistance to change were found to be the top two obstacles. Proper training should be provided to workers to reduce employee resistance and there should be more participation in different stages of implementation. Real problem for the construction sector in Libya is the implementation of quality projects. The main factors influencing the implementation of quality management systems in construction projects are top management commitment, communication, teamwork, employee involvement, and work environment and culture. Following a comprehensive review of several studies on TQM and also considering the importance of critical effecting factors of manufacturing sector in Libya, this study proposed 12 components or factors of TQM for LISCO. A questionnaire made to help finding out the factors and components those affecting implementation of TQM system in the company and identifying correlation between these variables (components). Descriptive statistics and SPSS analysis were employed to indicate the TQM effective components for best implementation which can be applied in order to achieve quality performance.
Improved Quantification of Ocean Carbon Uptake by Using Machine Learning to Merge Global Models and pCO2 Data

The ocean plays a critical role in modulating climate change by sequestering CO2 from the atmosphere. Quantifying the CO2 flux across the air‐sea interface requires time‐dependent maps of surface ocean partial pressure of CO2 (pCO2), which can be estimated using global ocean biogeochemical models (GOBMs) and observational‐based data products. GOBMs are internally consistent, mechanistic representations of the ocean circulation and carbon cycle, and have long been the standard for making spatio‐temporally resolved estimates of air‐sea CO2 fluxes. However, there are concerns about the fidelity of GOBM flux estimates. Observation‐based products have the strength of being data‐based, but the underlying data are sparse and require significant extrapolation to create global full‐coverage flux estimates. The Lamont Doherty Earth Observatory‐Hybrid Physics Data (LDEO‐HPD) pCO2 product is a new approach to estimating the temporal evolution of surface ocean pCO2 and air‐sea CO2 exchange. LDEO‐HPD uses machine learning to merge high‐quality observations with state‐of‐the‐art GOBMs. We train an eXtreme Gradient Boosting (XGB) algorithm to learn a non‐linear relationship between model‐data mismatch and observed predictors. GOBM fields are then corrected with the predicted model‐data misfit to estimate real‐world pCO2 for 1982–2018. The resulting reconstruction by LDEO‐HPD is in better agreement with independent pCO2 observations than other currently available observation‐based products. Within uncertainties, LDEO‐HPD global ocean uptake of CO2 agrees with other products and the Global Carbon Budget 2020.
Enhanced biogas production from co-digestion of intestine waste from slaughterhouse and food waste

The presence of higher protein and lipids contents of the intestine waste from slaughterhouse affects the anaerobic digestion (AD) process due to volatile fatty acids accumulation and ammonia toxicity. The aim of the present batch reactor study was to evaluate the effect of the mixing ratio on anaerobic co-digestion of intestine waste from the slaughterhouse (IWS) and carbon-rich food waste (FW) to enhance the biogas production and to optimize the C/N ratio for improving the efficiency and better performance of AD. Biogas productions were estimated for various mixing ratios on volatile solid (VS) basis (IWS/FW: 1:1, 1:2, 1:3, 1:4, and 1:5) keeping the inoculum to substrate ratio maintained at 0.5 as per German method VDI 4630. On the basis of the present study, the biogas productions of different mixing ratios at the end of 30th day were found to be on the order of 0.43 (1:2) > 0.39 (1:3) > 0.38 (1:1) > 0.36 (FW) > 0.35 (1:4 and 1:5) > 0.18 (IWS) L/g of VS added. Similarly, the VS removal efficiencies wer.
Molecular changes of aquatic humic substances formed from four aquatic macrophytes decomposed under different oxygen conditions

ABSTRACT Aquatic macrophytes’ decomposition is a source of recalcitrant carbon in the long term contributing to humic substances (HS) formation. Understanding the influence of plant detritus quality and oxygen availability over molecular changes of these compounds provides ecological information related to their cycling. This study described the molecular variation of dissolved HS from Eichhornia azurea, Egeria najas, Oxycaryum cubense and Salvinia molesta decomposition under aerobic and anaerobic conditions. The aquatic HS formed from the four aquatic macrophytes showed similar features (e.g. molecular weight and aromaticity). This fact indicates little influence of the detritus quality or availability of oxygen on the fulvic acids (FA) and humic acid characteristics. Under aerobic condition a decrease in the polysaccharides content in FA occurred. HS from E. najas were related to less-recalcitrant features, while HS from S. molesta were related to recalcitrant.

Inch‐Size Single Crystal of a Lead‐Free Organic–Inorganic Hybrid Perovskite for High‐Performance Photodetector

Large‐size crystals of organic–inorganic hybrid perovskites (e.g., CH3NH3PbX3, X = Cl, Br, I) have gained wide attention since their spectacular progress on optoelectronic technologies. Although presenting brilliant semiconducting properties, a serious concern of the toxicity in these lead‐based hybrids has become a stumbling block that limits their wide‐scale applications. Exploring lead‐free hybrid perovskite is thus highly urgent for high‐performance optoelectronic devices. Here, a new lead‐free perovskite hybrid (TMHD)BiBr5 (TMHD = N,N,N,N‐tetramethyl‐1,6‐hexanediammonium) is prepared from facile solution process. Emphatically, inch‐size high‐quality single crystals are successfully grown, the dimensions of which reach up to 32 × 24 × 12 mm3. Furthermore, the planar arrays of photodetectors based on bulk lead‐free (TMHD)BiBr5 single crystals are first fabricated, which shows sizeable on/off current ratios (≈103) and rapid response speed (τrise = 8.9 ms and τdecay = 10.2 ms). The prominent device performance of (TMHD)BiBr5 strongly underscores the lead‐free hybrid perovskite single crystals as promising material candidates for optoelectronic applications.
The role of nitric oxide on spermatogenesis in infertile men with azoospermia

Objectives: The underlying pathophysiological mechanisms of azoospermia is still unclear. The aim of the study was to evaluate nitric oxide synthase (NOS) isoforms and free radical release in testicular sperm extraction (TESE) in infertile men with azoospermia. Materials and methods: The study included 40 men (mean age: 37.2±2 years; range 25 to 55 years) with azoospermia which were divided into two groups: spermatozoa-present (n=20) and spermatozoa-absent (n=20). Testicular samples were examined morphologically, immunohistochemically, and biochemically. The TESE samples were examined according to number of mast cells stained with toluidine blue; immunohistochemically with three types of NOS isoforms, and free radicals were measured with chemiluminescence method, respectively. Results: Endothelial NOS (eNOS) reaction in spermatozoa-present group was considerably higher than spermatozoa-absent group (p<0.001). Compared to the spermatozoa-present group, inducible NOS (iNOS) reaction was higher than the spermatozoa-absent group (p<0.05). Neuronal NOS (nNOS) reaction was only prominent in Leydig cells in both groups. Mast cells increased (p<0.05) in the interstitial area surrounding seminiferous tubules in spermatozoa-absent samples. Superoxide radical generation in spermatozoa-present samples was significantly lower (p=0.0003). The peroxynitrite ratio in spermatozoa-absent samples was significantly higher (p=0.0038). Conclusion: These results suggest that eNOS, iNOS, and mast cells play an important role in spermatogenesis process in azoospermic men.

Resource recovery from wastewater treatment: challenges, opportunities and guidance for planning and implementation

Considering the current resources scarcity, Wastewater Treatment Plants (WWTP) should be adapted to become more sustainable. For example, it is possible to recover resources present in municipal wastewater. However, regional studies about integration of resource recovery processes at different scales or about the main barriers to implementation in developing countries are missing in the literature. Also, there is a need for planning methodologies to identify the most sustainable solution in each context. Understanding the current situation is an essential step to support planning and accelerate resource recovery implementation. To address these issues this thesis aims to guide planning, technology and policy development towards resource recovery from municipal WWTP in large cities of developing countries. This thesis presents a comprehensive knowledge base for wastewater treatment plant managers and decision-makers leading to a better understanding of resource recovery solutions and the actions needed to facilitate implementation. The methodology comprised critical literature reviews and two case studies. Secondary data from literature and primary data (obtained through questionnaires) were collected and analysed. Megacities in developing countries are analysed in the papers, with the focus on the Macrometropolis of Sao Paulo, which is the most populous area in the Southern Hemisphere. The current situation shows a low implementation of resource recovery practices in the region, and local conditions affect the implementation of water reuse, and nutrients and energy recovery. A framework consisting of eleven steps is proposed to support planning and decision-making on resource recovery from wastewater. This new tool was tested and can be applied by decision-makers in wastewater sector for better operation and management. Market, legislation, local economic development, and cooperation with stakeholders are relevant aspects covered in the analysis. There is a great potential to expand wastewater treatment integrated with nutrient and energy recovery strategies in developing countries. Potentials for phosphorus and energy recovery were estimated and some recovery scenarios are recommended. In conclusion, the findings can help planning and elaboration of resource recovery projects in wastewater treatment in urban areas and stimulate creation of public policies. The main research gaps identified in this thesis can guide further research and technological development in this field. (Less)
Image Saliency Detection via Two-Stream Feature Fusion and Adversarial Learning

: To achieve meaningful combination of low-level features and semantic information of salient regions or targets, and to obtain saliency detection results with more complete structure and clearer boundary, an algorithm of color image saliency detection via two-stream feature fusion and adversarial learning (SaTSAL) is proposed. Firstly, different levels of image features are extracted from bottom to top by means of a two-stream heterogeneous backbone network based on VGG-16 and Res2Net-50. Secondly, in each stream, different feature maps from the same level are fetched into one convolution tower module to enrich intra-level multi-scale information. Thirdly, a predicted saliency map is generated by top-down laterally fusing of cross-stream feature maps level by level, so as to effectively make full use of high-level semantic features and low-level image features. Finally, under the mainframe of conditional generative adversarial networks (CGAN), a higher structural similarity between detected results and salient objects can be strength-第
In-silico STUDIES OF AMENTOFLAVONE AND ITS DERIVATIVES AGAINST SARS-COV-2

The COVID-19 pandemic caused by SARS-CoV-2 infection is of global concern. The SARS-CoV-2 main protease (Mpro2, PDB ID: 6LU7), is an important SARS-CoV-2 enzyme in mediating viral replication and transcription, making it very strategic to be a drug target. Amentoflavone and its derivatives underwent molecular docking and 3D ligan-based pharmacophore modeling to analyze their molecular interactions against Mpro2 and evaluation for their absorption, distribution, metabolism, excretion, (ADME) properties. Fifty-one compounds had better docking parameters than comparison compound (remdesivir) and S29 is the best-docked compound (ΔG=-13.06 kcal/mol). Amentoflavone derivatives are promising candidates for novel anti-COVID agents. © 2021, Rasayan Journal of Chemistry, c/o Dr. Pratima Sharma. All rights reserved.
