Authors: Zhang Meixia 
Published: August 2021

Abstract
Infrastructure network is a fundamental factor of city size and urban expansion. The successful experience of many cities shows that increasing investment in infrastructure construction has significantly improved the speed and scale of urban development. Therefore, a quantitative analysis of the impact of urban infrastructure construction on urban development can lay the foundation for sustainable development of cities. This paper adopts the data of 264 cities in China from 2006 to 2018 from the aspect of road transportation network, Internet, ecological environment and industrial structure, and uses the gray correlation model and regression analysis to study the relationship and influence between China’s infrastructure and urban development.
Research on Environmental Information Disclosure of Polluting Industry Enterprises from the Perspective of Impression Management
Authors: Haiyan Zheng , Xinyu Wang 
Published: August 2021

Abstract
Environmental information disclosure is the main way for enterprises to convey their performance of environmental responsibility, and also an important tool for the government to carry out environmental protection work. Based on stakeholder theory, impression management theory and information asymmetry theory, this research regression analyzed the impact of corporate performance on environmental information disclosure for 112 listed companies in heavy polluting industries. The results show that the quality of environmental information disclosure of high-performing enterprises is higher than that of low-performing enterprises. The self-interested impression management greenwashing behavior adopted by enterprises in heavy polluting industries reduces the quality of environmental information disclosure. This study breaks through the previous single research from the perspective of financial information manipulation, analyzes the impression management behavior of enterprises on text information reflecting circular thinking, and enriches literature on environmental information disclosure.
A Comparative Study Between Different NCAPs and The Future of BNVSAP
Authors: Salhan Pranav , Jain Prasoon 
Published: August 2021

Abstract
India is the third largest road network which is used by one percent of the world’s total vehicle population. On this road network six percent of the total of global road traffic accidents occur. India is the sixth-largest car market in the world but is still the only country amongst the global top 10 car markets to not have a testing program. To reduce the number of road traffic accidents, many countries have come up with safety programmes such as Euro NCAP (New Car Assessment Program), US NCAP, Latin NCAP, etc. In 2014, Indian government proposed a similar safety assessment program called as Bharat New Vehicle Safety Assessment Program (BNVSAP) but it is since delayed in its implementation due to a number of reasons. The aim of this study is to compare existing NCAPS and the new BNVSAP and propose some improvements in it by studying the experiences gained by the older NCAPS and observing the difference in the situation of road traffic in India and in other countries by analysing real world accident data.
Multi-Response Optimization of Weld-process variables for Micro-Friction Stir Welding of Al6061(T6) and Cu101 sheets using TOPSIS method
Authors: Srujan Manohar M V N , Mahadevan K 
Published: August 2021

Abstract
This work is an attempt to identify the optimum weld-process variables for micro-friction stir welding of Al6061(T6) and Cu101 sheets using multi-response optimization. The experiments were conducted according to L9 orthogonal array with selected input variables namely tool-rotational speed and tool-travel speed. The response variables considered in this study are ultimate tensile strength, micro-hardness and surface-roughness which determine the strength of the welded-joint. The multi-response optimization approach namely Technique for Order Preference by Similarity to Ideal Solution(TOPSIS) method is used to determine the optimum process variables that provides the best value among all response variables. Finally, the optimal solution shows that multi-responses of micro-friction stir welds can be improved through TOPSIS method.

Published: August 2021

Abstract
In modern industrial era, the dimensional accuracy and surface finish are two major criteria in the selection of casting process. To achieve this paradise, lost foam casting is one of the casting processes. In this casting process, the shell is made by removal of expandable polystyrene or foam pattern with the application of heat. During the foam decomposition process, many problems have been generated such as bending, expansion, distending and crack of the shell. These problems may be eliminated by selecting the optimum ratio of coating materials. In this research work, zircon and aluminium silicate refractory coating materials with sodium silicate binder have been used with different composition and prepared the four test samples from them. For selection of best shell material composition, analytical hierarchy process is used.

Authors: Rama Rao Y Seetha , Srujan Manohar M V N , Siva Praveen S V V 
Published: August 2021

Abstract
The need for more efficient design has become a main concern to work with a good range for angle of attack (AOA) to reduce the stall formation. In this project, two types of NACA series airfoils i.e., symmetrical and asymmetrical profiles depending on their usage in various sectors are compared. The profile of the airfoils is imported into ANSYS Fluent from the data files. The 2D geometry of the airfoils is simulated under two different wind velocitiesi.e., at 3m/s and 15m/s respectively. The graphs are plotted for comparing coefficients of lift (CL) and drag (CD)withrespect to the angle of attack(α) for symmetrical and asymmetrical airfoils. The stall formation with change of geometry and angle of attack is also observed.
Energy storage using NaOH phase change material for solar thermal application at constant heat flux
Authors: Kumar B , Das M K , Roy J N 
Published: August 2021

Abstract
There is a mismatch between energy demand by consumers and supply from the sun. Therefore, we store Solar Energy in the phase change material (PCM) for storage energy. We used medium temperature range salt, Sodium hydroxide (NaOH), melting temperature at 591 K and heat of fusion 160 kJ/kg. We did the numerical simulation using COMSOL Multiphysics®, we kept radially variable surface flux at the bottom of the container. Linearly variable flux at the centre is 78 kW/m2 and 18 kW/m2 at the periphery. For numerical analysis, we used 3D enthalpy based model. We found that the bulk temperature of NaOH reaches about 800 K after 6 hours and total energy stored by the PCM is about 21 MJ. This amount of energy is very useful for domestic and small industrial process.

Published: August 2021

Abstract
The photovoltaic thermal collector (PVT) produces electricity and extracts heat from a common area exposed to solar radiation. The present work provides a methodology to assess the potential of PVT at any location. The climate of Pantnagar (a town situated in the Terai belt of Uttarakhand) is selected for the study. An unglazed PVT air heating collector is modelled, taking account of both electrical and thermal aspects of design. The performance of the collector is then simulated on four days, representing average weather of four seasons observed in North Indian Plains, in correspondence with the typical meteorological year (TMY) data of 2006-2015 for the location. The diode parameters and characteristic curves of PV module selected for PVT are obtained for reference and operating conditions. The operating temperature of solar cell and heated air are plotted after convergence of numerical solution at available data points. Finally, electrical and thermal power output of the PVT with associated optical and thermal losses are obtained. The highest electrical power output of 223 W (136 W/m2) is observed at 12:20 hours (IST) on equinox of September while highest thermal power output of 411 W (251 W/m2) is obtained at 12:20 hours (IST) on summer solstice.

Published: August 2021

Abstract
Scholars and scientists have been attempting to discover ways to control and lessen the reverberation of concurrent fires such as forest fires, building fires, and other various space fires but no convincing solutions have been concluded from their studies so far. The fundamental genesis of these types of fires concerns the unstable nature of the flames and considerable unpredictability associated with them. This led us to make an effort to study the etiquette of such flames – an experimental setup with rather ideal conditions was devised and an in-depth study was carried out. The present study predominately covers the study of fire propagation phenomena and the zeal of fire control in our daily life. This study includes the review of the varying regression rates and fire spread rates of flames as noticed in matchsticks when spaced in a linear orientation. The deportment instability of the flames will give us an insight into the heterogeneous fire propagation phenomenon and its control. Intuition into the heterogeneous fire propagation is expected for essential fire safety and, on its basis, an algorithm for the same is to be formulated. With this understanding along with the existing information, it might give us some possible solution to the reduction of such kinds of fires in buildings, forests, space propulsion systems and, large-scale fires in industries.
Comparison of the accuracy of DFT methods for reactions with relevance to nitrogenase
Authors: Torbjörnsson Magne , Ryde Ulf 
Published: August 2021

Abstract
We have studied the accuracy of 16 different density functional theory methods to reproduce experimental data for bond lengths, angles, vibrational frequencies, as well as enthalpies and entropies for the binding of N2, H2, CO and hydride ions to various transition-metal complexes (with Fe, Ni, Cr, Mo and W) with relation to nitrogenase. We show that generalized gradient approximation functionals give better structure-related parameters, whereas hybrid functionals often give better energies. However, the BLYP and B97D functionals seem to give reasonably accurate results for both types of properties. Geometries and entropies are converged with split-valence basis sets, but energies and vibrational frequencies (and therefore also thermal corrections) in general require a basis set of triple-zeta quality. Dispersion corrections are important to obtain accurate energies (contributing by up to 57 kJ mol−1), as well as structures.

Published: August 2021

Abstract
Reinforcement learning (RL) is a foundation of learning in biological systems and provides a framework to address numerous challenges with real-world artificial intelligence applications. Efficient implementations of RL techniques could allow for agents deployed in edge-use cases to gain novel abilities, such as improved navigation, understanding complex situations and critical decision making. Toward this goal, we describe a flexible architecture to carry out RL on neuromorphic platforms. This architecture was implemented using an Intel neuromorphic processor and demonstrated solving a variety of tasks using spiking dynamics. Our study proposes a usable solution for real-world RL applications and demonstrates applicability of the neuromorphic platforms for RL problems.
Reaffirming the phyllocladoid affinities ofHuncocladus laubenfelsii(Podocarpaceae) from the early Eocene of Patagonia: a comment on Dörkenet al. (2021)
Authors: Andruchow-Colombo Ana , Wilf Peter , Escapa Ignacio H 
Published: August 2021

AbstractWe discuss a recent assessment by Dörken et al. (2021) regarding the affinities of the Eocene fossil species Huncocladus laubenfelsii from Laguna del Hunco (Patagonia, Argentina). We originally (Andruchow-Colombo et al., 2019) assigned this species to the conifer family Podocarpaceae as the first certain South American macrofossil record of the phyllocladoid lineage (Huncocladus+Phyllocladus), based on a combination of numerous macro- and micromorphological vegetative characters. However, Dörken et al. (2021) rejected the podocarpaceous affinity of H. laubenfelsii and considered it to be more closely related to the cycad genera Bowenia or Eobowenia. Their assessment was based almost entirely on two cuticular characters, with only superficial consideration of the abundant additional evidence available that included several diagnostic macromorphological features. We review the two characters mentioned by these authors, and other features, and find that their suggestion is contradicted by the available evidence, maintaining our original assignment. Critical characters include presence/absence of a midvein, secondary venation pattern, arrangement and general morphology of the photosynthetic structures, and morphology and disposition of epidermal cells.

AbstractIntroductionMany diseases can imitate inflammatory bowel disease [IBD] clinically and pathologically. This review outlines the differential diagnosis of IBD and discusses morphological pointers and ancillary techniques that assist with the distinction between IBD and its mimics.MethodsEuropean Crohn’s and Colitis Organisation [ECCO] Topical Reviews are the result of an expert consensus. For this review, ECCO announced an open call to its members and formed three working groups [WGs] to study clinical aspects, pathological considerations, and the value of ancillary techniques. All WGs performed a systematic literature search.ResultsEach WG produced a draft text and drew up provisional Current Practice Position [CPP] statements that highlighted the most important conclusions. Discussions and a preliminary voting round took place, with subsequent revision of CPP statements and text and a further meeting to agree on final statements.ConclusionsClinicians and pathologists encounter a wide variety of mimics of IBD, including infection, drug-induced disease, vascular disorders, diverticular disease, diversion proctocolitis, radiation damage, and immune disorders. Reliable distinction requires a multidisciplinary approach.

AbstractAimsData standards are consensual specifications for the representation of data arising from different sources. If provided with internationally harmonized variables, permissible values, and clinical definitions, they have the potential to enable reliable between- and within-country analysis of care and outcomes. The European Unified Registries for Heart Care Evaluation and Randomised Trials (EuroHeart) is a European Society of Cardiology project that allows participating countries to collect patient data to undertake quality improvement, observational studies, drug and device surveillance, and registry-based randomized controlled trials for cardiovascular conditions. This paper describes the methodology for development of harmonized data standards for EuroHeart.Methods and resultsWe adopted a five-step process for the development of harmonized data standards. The process includes (i) identification of clinical domains for data standard development by evaluating specific cardiovascular conditions with high prevalence and opportunities for quality improvement; (ii) construction of data standard specifications by systematic review of the literature; (iii) selection of variables by a domain-specific Working Group using a modified Delphi method; (iv) validation of data standards by a domain-specific Reference Group; and (v) implementation of the developed data standards into an IT platform.ConclusionThis paper describes the approach adopted by EuroHeart for the development of clinical data standards for cardiovascular disease. The methodology has been developed and is used by EuroHeart to create a suite of international data standards for cardiovascular diseases. The EuroHeart data standards may be used to systematically capture individual patient data about clinical care and for research.
DGCR8 microprocessor defect and deregulation of its expression in thyroid cancer
Authors: Rodrigues Lia , Dias Carolina , Macedo Sofia , Soares Paula , Vinagre João 
Published: August 2021

Abstract

Background
The alteration of microRNA (miRNA) processing is a driver event in several tumors including thyroid cancer (TC). Upon the discovery of DICER mutations affecting the miRNA biogenesis in TC, other genes encoding proteins with similar functions have been studied. The DiGeorge Critical Region 8 (DGCR8) gene holds a critical role in miRNA biogenesis as a microprocessor complex component. Previous studies identified a hotspot DGCR8 mutation - the variant c.1552G &gt; A (p.E518K) that alters canonical miRNA production. As miRNAs are necessary to accurately establish thyroid follicles and hormone synthesis, the deregulation of their expression are common in TC. The goal of this study was to characterize the variant p.E518K of DGCR8 in thyroid lesions and evaluate its expression.

Methods
242 samples of 214 patients with tumor or tumor-like lesions of thyroid were evaluated by direct sequencing for the presence of c.1552 G &gt; A (p.E518K). Formalin-fixed paraffin embedded (FFPE) sections of these lesions were studied for DGCR8 immunoexpression. When frozen tissue was available, DGCR8 mRNA expression was analyzed by quantitative PCR (qPCR).

Results
The presence of the variant c.1552G &gt; A (p.E518K) was a rare event in our series. Only 1 case was found mutated, and it corresponded to a poorly differentiated thyroid carcinoma (PDTC). Unexpectedly, mRNA DGCR8 expression and DGCR8 expression shown an aberrant expression in PDTC cases which could lead to a miRNA downregulation.

Conclusions
The results obtained so far point that DGCR8 may have a role in thyroid carcinogenesis. Although mutations are rare, aberrant expression affecting miRNA expression seems to be a common event.

Published: August 2021

Abstract

Background
With the increase of the average life expectancy, and the increase in chronic diseases, consequently also increases the consumption of medicines. Polymedication leads to an increase in drug-related problems, particularly in the elderly. Prescription of medications potentially inappropriate, which can have a harmful impact on the quality of life of the elderly. The aims are identifying and classify potentially inappropriate medication according to the recent criteria of Beers.

Methods
We conducted an observational study in the nursing home. The sample consisted of 45 seniors of 65 years of age or older, take at least two different mediations at the same time. The data collection was made to a questionnaire with sociodemographic characteristics and clinical profile.

Results
The female sex predominates with 32 people (71.1%), with a very high average age (86.02 years ± 7.6). In the 45 respondents it appears that they take a minimum of 4 drugs (2.2%) and a maximum of 16 (4.4%), with an average of 9.7 daily drugs per individual. The most prescribed drugs are for the nervous and the cardiovascular system, and 34 drugs were considered potentially inappropriate medication use in older adults, 23 drugs of which were recommended to be avoided and the rest were recommended to be used with caution and dose reduction.

Conclusions
It is necessary more personalised criterion for prescription and dispensation of medication to elderly people. It is necessary to develop habits and practices that create higher prudence when prescribing medication and its rational use.
