COMBINATION OF ARCHITECTURAL, ENVIRONMENTAL AND SOCIAL ASPECTS IN URBAN STORMWATER MANAGEMENT. A CASE STUDY OF THE UNIVERSITY CAMPUS

Water has been vital for the development of the cities, used not only for drinking and food production but also for transportation, the production of goods, for protection against enemies (ditches, moats) as well as for micro-climate mitigation, as in the former Muslim towns at the Iberian Peninsula. The present concepts of water presence and management in the cities still have their roots in the XIX century, when the role of water in transmitting diseases and the significance of proper hygiene and sanitation were first understood. The technical concepts of centralised water provision and wastewater collection were then developed, and they continue to shape the nowadays urban areas, especially in developed and industrialised countries [1]. Starting from the first infrastructure built in the XIX century, stormwater has been looked at as one of the elements to be included within the engineered systems for water and wastewater transport [2,
The Protective Effect of Recombinant Human Brain Natriuretic Peptide on Acute Kidney Injury after Liver Transplantation

Background: To investigate the protective effect of recombinant human Brain Natriuretic Peptide (rhBNP) on Acute Renal Injury (AKI) after liver transplantation. Methods: A retrospective cohort study was analyzed by collecting clinical and epidemiological data of 136 patients who underwent liver transplantation from March 2018 to December 2020. Patients were divided into rhBNP group (88 cases) and non-rhBNP group (48 cases) according to whether they were treated with rhBNP after the operation. The changes of liver and renal function after operation and the difference of clinical prognosis were studied. Results: Patients (50.0%) in non-rhBNP group had a significantly higher incidence of AKI than those (31.8%) in rhBNP group (P=0.04), especially the AKI stage I. Average levels of serum creatinine within seven days were significantly lower in the rhBNP group than that in the non-rhBNP group (P=0.01). The rate of postoperative CRRT did not differ significantly between the two groups. However, the use of furosemide was significantly greater in the non-rhBNP group (P<0.001). The in-hospital mortality rate after liver transplantation was 18.2% in the rhBNP group and 22.9% in the non-rhBNP group. The mean length of Intensive Care Unit (ICU) stay in the rhBNP group was 2.9 ± 5.0 days, significantly shorter than the 6.4 ± 16.2 days in the non-rhBNP group (P=0.02). There were significant differences in the survival distributions of patients after liver transplantation with AKI versus non-AKI (P<0.001) by Kaplan-Meier curve analysis. Conclusion: The application of rhBNP in patients after liver transplantation could reduce kidney injury, reduce the risk of postoperative AKI, increased urine volume after surgery, decrease the length of stay in ICU and improve the clinical prognosis of patients. It provided a new path for the clinical prevention and treatment of AKI after liver transplantation.

Forced Expiratory Flow FEF 25-75 % and Body Mass Index among Young Adolescents

Received: 03-07-2021 / Revised: 26-07-2021 / Accepted: 17-08-2021 Corresponding author: Dr. Yogesh Kumar Yadav Conflict of interest: Nil Abstract In India, undernutrition coexists with obesity, thus demonstrating a double burden of the disease. The effect of the increased BMI and the body fat percentage on the pulmonary functions has been studied extensively. The effect of undernutrition on the pulmonary functions needs attention. FEF 25-75 (L/S) describes the amount of air expelled from the lung during the middle half of the forced vital capacity test. The study was conducted over 300healthy students (13-19 yrs.), 155 male subjects and 145 female subjects. Medspiror, computerised spirometer was used to record lung function parameter Forced expiratory flow (FEF25-75%). Pulmonary function parameter in different Body Mass Index (BMI) groups was tabulated. 262 subjects had BMI less than 18.5 (underweight), 36 subjects and BMI between 18.5-25 (normal weight), and 2 subjects had BMI more than 25 (overweight). Majority subjects (262) were underweight. subjects who were having low BMI had low Forced expiratory flow (FEF25-75%) as compared to normal BMI subjects. Our study also showed a marked reduction in FEF25-75% in the underweight group. This could be due to malnutrition. It is observed that PFT value FEF25-75% were significantly reduced in underweight young individuals, compared between males and females this study showed fall is more in female than males. Under nutrition should be identified as early as possible and should be corrected in order to ensure health of young individuals.
An experimental study on micro-scale flow boiling heat transfer

New experimental flow boiling heat transfer results in micro-scale tubes are presented in this paper. The experimental data were obtained in a horizontal 2.32 mm I.D. stainless steel tube with heating length of 464 mm, R245fa as working fluid, mass velocities ranging from 50 to 500 kg/ms, heat flux from 5 to 55 kW/m, exit saturation temperatures of 22, 31 and 41 C, and vapor qualities from 0.05 to 0.99. Flow pattern characterization was also performed from images obtained by high speed filming. Heat transfer coefficient results from 2 to 6 kW/mK were measured. It was found that the heat transfer coefficient is a strong function of the heat flux, mass velocity and vapor quality. The experimental data were compared against the following micro-scale flow boiling predictive methods from the literature: Bertsch et al. (2008), Saitoh et al. (2007), Kandlikar and Balasubramanian (2004), Zhang et al. (2004), Thome et al. (2004) and Liu and Winterton (1991). Although not satisfactory, Thome et al. (2004) worked the best when predicting the present database.

An Ensemble Approach to Unsupervised Anomalous Sound Detection

The task of anomalous sound detection (ASD) is to determine whether an observed sound is anomalous or normal. Both supervised and unsupervised approach can be adopted for the ASD task. In supervised approach anomalous and normal data are used in training whereas in unsupervised approach only normal data are used for training. In this work, we provide an overview of the systems developed for the task 2 i.e., unsupervised detection of anomalous sounds for machine condition monitoring, of the DCASE 2020 challenge. We employ various handcrafted local representations from the short-time spectral analysis of sounds. We also use ﬁsher vector encoding - a learned global representations obtained from local representations of sound. Autoencoder variants and copy detection approaches are applied on the top of local representations and a standard GMM classiﬁer is used with ﬁsher vector encodings for unsupervised detection of anomalous sounds.
Title: The Influence of the Gradient Infill of PLA Samples Produced with the FDM Technique on Their Mechanical Properties

Three-dimensional printing is a dynamically developing field of industry. Its main advantage is the small amount of waste, no need to use specialized tools, and easy control of the mechanical properties of the printed model. One of the most popular techniques of 3D printing is FDM. The main factor influencing the mechanical properties of 3D-printed materials is the filling density. The aim of this study was to determine the mechanical properties of porous structures with a porosity gradient of PLA samples printed using the FDM technique. The accuracy of mapping the structures by computed tomography was assessed, and then a static compression test was performed. It has been shown that the strength properties increased with the increase in the filling density. The highest value of compression strength, amounting to 41.2 MPa, was observed for samples made of PLA with an 80% filling degree, whereas the lowest value of compression strength was found in PLA-T samples with a filling degree of 10%, reaching only 0.6 MPa. It was found that not only the core filling density, but also the outer layers, influences the mechanical properties. The assessment of spatial architecture allowed for a qualitative and quantitative assessment. The obtained images from the computed tomograph showed that the designed sample models were correctly reproduced in the entire volume.
Ice surface near melting point: Effects on the tropospheric ice

: Atmospheric gases and chemical impurities can be stored and chemically transformed in the tropospheric ice. Impurities are rejected during freezing of the ice to the grain boundaries, free ice surfaces or inclusions. Surface snow and tropospheric ice, however, may be exposed to high temperatures and, eventually, the gases and chemical impurities can be released into the environment. It is important to study the surface structure and transport mechanisms at temperatures near the melting point because the location of impurities and their interactions with water molecules in the ice are not yet sufficiently explained. In this work, the evolution of a scratch on the bicrystalline ice surface was studied at –5℃. The surface transport mechanisms near the melting point were studied and, as a consequence, the surface structure could be determined. An ice sample was kept immersed in ultra-pure silicone oil to prevent evaporation and, thus, isolate the effect of surface diffusion. The ice sample was made with water with chemical conditions similar to the water of polar ice sheets. Photographs of the scratch were taken periodically, for approximately 50 hours, using a photographic camera coupled to an optical microscope. From these images, the evolution of the width of the scratch was studied and the surface diffusion was the dominant transport mechanism in the experiment. Finally, the ice surface self-diffusion coefficient at –5℃ was determined and it was very similar to the super-cooled water diffusion coefficient. A liquid-like behavior of ice surfaces near the melting point was found and it could have a strong influence on the reaction rates with atmospheric gases.
Germany as a role model for structural adjustment of peripheral Eurozone economies: the Portuguese case

This paper aims at analyzing the structural changes that occurred in the Portuguese economy after the 2010/2013 sovereign debt crisis, compared with what occurred in Germany and using the current debate surrounding the new reform of the Eurozone as a backdrop. We thus intend to find out whether a peripheral southern economy like Portugal and the Eurozone’s nuclear economy (Germany) have become closer and, if so, what that means in terms of the sustainability of the Eurozone as a set of different economies sharing the same currency. The study will be framed in the varieties of capitalism theory and in the theory of growth regimes.

Learning Circular Economy by Hands-on Experiments: A Case- Study on Phosphorus Recovering from Wastewater at School

Circular economy (CE) is now gaining attention in academia and industry as an emerging model for minimizing primary resource depletion, waste and greenhouse gas emissions. In the present work, we present a learning pathway, designed for high schools, useful to introduce some basic concepts of CE among youngsters by starting from a laboratory experience. The path was developed in the framework of the European project Raw Matters Ambassadors at Schools (RM@Schools), an innovative program to make science education attractive for youngsters which and to promote a wide dissemination action on raw material-related themes in Schools and Society. In this context, lab experiments to approach raw materials (RMs) considered critical by EU and the necessity of their recovery were set up for high school students. Phosphate rock (P) is one of the critical RMs for EU, and it is primarily used in agriculture. After 2033 Iit is expected a huge decline in P extraction and consequently, a dramatic decrease in fertilizers, food and feed. The goal of the lab experience presented here is to educate students that P can be recovered from secondary resources such as urine, a component of wastewater. The laboratory activities are planned in a theoretical training under the teacher guidance and another practice where students become the main protagonists of all phases of the work (from design to evaluation). The laboratory activity is composed by three experiments with various levels of difficult. By using the material created for this learning path, students become familiar with the concept of biogeochemical cycles and specifically nitrogen and phosphorous cycling, and learn that in CE end-of-life products are considered as resources for another cycle. In addition, consideration must be given to the interactions between materials to determine the best circular solution. Students can be aware of the benefits of closing material loops in a simple and engaging way.
Coherence in George Orwell ' s 1984 : A Linguistic Study

The primary aim of the study is to investigate the notion of coherence in Orwell‟s Nineteen Eighty-Four from a metadiscoursal perspective. In this respect, the study adopts Hyland's (2005) interpersonal model of metadiscourse markers. The study attempts to outline metadiscourse markers contribution to the overall coherence of discourse. A secondary aim is relating the findings of the study to the implication which metadiscourse devices might have on achieving a preferred interpretation of English literary texts. The findings of this study reveal that metadiscourse devices contribute to raise the level of interaction between the writer and the reader. This enables readers to achieve a preferred interpretation of the text which in return contributes to raise the overall coherence of discourse.
Learning-based Control for Hybrid Battery Management Systems

Battery packs of electric vehicles are prone to capacity, thermal, and aging imbalances in their cells, which limit power delivery to the vehicle. In this chapter, a hybrid battery management system (HBMS), capable of simultaneously equalizing battery capacity and temperature while enabling hybridization with supercapacitors, is investigated. We use model-free reinforcement learning to control the HBMS, where the control policy is obtained through direct interaction with the system’s model. Our approach exploits the soft actor-critic algorithm to handle continuous control actions and feedback states, and deep neural networks as function approximators. The validation of the proposed control method is performed through numerical simulations, making use of numerically efficient models of the energy storage and power converters developed in Modelica language.
A novel de novo TP63 mutation in whole‐exome sequencing of a Syrian family with Oral cleft and ectrodactyly

The proband presented with both orofacial clefting and ectrodactyly but not ectodermal dysplasia as typically seen in ectrodactyly, ectodermal dysplasia, and cleft lip/palate syndrome‐3. A paternal uncle with only an oral cleft was deceased and unavailable for analysis.
Investigating the dynamics of a buck converter with time-delay feedback control

The paper deals with the dynamics features of a closed automatic control system based on a buck converter with a function to control nonlinear dynamic processes. A comprehensive analysis of the system under study is carried out using both small-signal average dynamic models and nonlinear dynamic models. For the first time, a small-signal average model of a system with a control function for nonlinear dynamic processes based on a time-delay feedback control has been obtained. The influence of this control method on Bode plots of an open system is shown. It is noted that the use of the time-delay feedback control ensures the stability of both the equilibrium point of the small-signal average model and the fixed point of the periodic mode of the nonlinear dynamic model of the system under consideration. This enables to achieve high quality output voltage. The application of the time-delay feedback control does not require to correct the system parameters, which ensures a given speed and low losses in the power switch of the converter. In addition, the quality of the transition process in the system is improved, namely, oscillation is eliminated and overshoot is reduced. Using the time-delay feedback control, it is possible to provide the desired dynamic mode in the areas of instability of the initial system without controlling nonlinear dynamic processes, which makes it possible to increase the speed due to the small time constant of the regulator. These results were obtained for the first time and can be used in the design of pulse power supply systems of a wide variety.
(NASPGHAN) Position Paper on the Diagnosis and Management of Pediatric Acute Liver Failure

Pediatric acute liver failure (PALF) is a rare, rapidly progressive clinical syndrome with significant morbidity and mortality. The phenotype of PALF manifests as abrupt onset liver dysfunction which can be brought via disparate etiology. Management is reliant upon intensive clinical care and support, often provided by the collaborative efforts of hepatologists, critical care specialists, and liver transplant surgeons. The construction of an agebased diagnostic approach, the identification of a potential underlying cause, and the prompt implementation of appropriate therapy can be lifesaving. However, the dynamic and rapidly progressive nature of PALF also demands that diagnostic inquiries be paired with monitoring strategies for the recognition and treatment of common complications of PALF. While liver transplantation can provide a potential life-saving therapeutic option, the ability to confidently determine the certainness that liver transplant is needed for an individual child has been hampered by a lack of adequately tested clinical decision support tools and accurate
