Map representation: all the land and sea which is written
Authors: Kang Jianjun , Luan Zhili , Li Chunping
Published: May 2022

Space cannot exist only as a given place where social relations and social processes operate, which would imprison the spatial imagination of literary geography. The absence of the spatial dimension in social theory largely reduces the imagination of geography and the creativity of literature. Literary painting has become a key way of understanding our world, and literature creates a much grander world. Every time we open a nautical chart, we find the lost imperial sailors on the edge of the world, winding up on the voyage. Spatial cognition is an important area of research in cognitive science, and the problem of space is first and foremost a problem of geography, but also an important problem that is being studied in psychology, cartography, information science, computer science, and artificial intelligence, among other disciplines. A map is a planar representation of land territorial possession and maritime territorial possession, and at the same time, a map embodies a transcendent knowledge or a symbol of absolute power. Along with the exploration of new worlds and the reorganization of old societies, we can see that maps are at the same time an expression of language and an expression of emotion while reading the space they bring us.

Supply chain informed principal model with quality uncertainty and information asymmetry in green supply chain
Authors: Zhang Huan , Zhao Yichen
Published: May 2022

In the green supply chain, due to factors such as technical level and capital investment, quality uncertainty often occurs. At the same time, manufacturers often know more about the uncertainty than the retailers they serve. To address the concerns raised above, we apply the informed principal model and consider a two-echelon green supply chain consisting of one unreliable manufacturer and one retailer. The manufacturer, as the principal, has private information about the green degree, while the retailer only knows its prior probability. We first study the underlying model under symmetric information. Then, under the information asymmetry, we construct a low-information-density model and an interim-efficient model. Finally, the numerical comparison results show that our propositions are valid. The results show that the low-information-density model can eliminate the information asymmetry, but it imposes high signaling cost on the high-quality manufacturer. The interim-efficient model can indeed reduce the cost and the distortion of the wholesale quantity. Moreover, it is worth mentioning that there is a specific threshold for the retailer's prior probability. When the prior probability is greater than this threshold, the interim-efficient model is better than the low–information-density model; otherwise, they are equivalent. Simultaneously, the higher the prior probability, the higher the manufacturer’s revenue. If the manufacturer wants to obtain more benefits, he must increase the retailer's trust by operating with integrity and building a brand effect.

Published: May 2022

With rapid development of hydrogen energy industry, liquid hydrogen, as a carrier with the highest energy storage density, is an effective way to ensure the large-scale application of hydrogen energy. Thrust bearing, which is the core component of hydrogen liquefaction turbine expander, has always been difficult to design. In this paper, the stress characteristics of the thrust bearing for hydrogen liquefaction are analyzed, and the analysis for designed prototype is performed. The numerical simulation results are compared with the design method. Results show the optimum clearance of thrust bearing and clearance of closed bearing has obvious influence on the peak value and position of stiffness caused by eccentricity. Numerical simulation results reflect the internal flow structures in bearing clearance, while the maximum stiffness is relatively conservative compared to analysis of radius ratio.

Authors: Li Jingjie , Wang Jiachen , Liu Changmeng
Published: May 2022

Wire- Arc Additive manufacture (WAAM) has been widely applied in metal field to control metal structure and microstructure. GH4169 is well fit to the WAAM due to its excellent weldability. While the columnar crystal has greater growth advantage than equiaxed crystal, so the superalloy GH4169 whose grain boundary induce its high temperature mechanical property will have fewer boundaries that can increase the property. While the shape of AM sample can be controlled, growth direction of columnar crystal can be adjusted through the heating method. If t growth directions of columnar crystals are consistent, the number of grain boundaries well induce largely. We can use different heating method and compare the result of growth direction. While the temperature environment at the top which decides the growth direction fit the requestion of growth direction, we can get the columnar that grows as we design.

The western Himalayan syntaxis represents the region where the major Himalayan structures abruptly curve and the cause of the curvature and the tectonic geomorphology of the region has not been fully explored. The lack of detailed structural maps with extensive field-based data are missing, which is mainly because of the political problems related to border sharing between Pakistan, India, and Afghanistan. However, and fortunately, the usage of satellite derived images has overcome such constrains by providing a robust platform to remotely map such regions. Therefore, the present study was aimed to supplement our previous works in the region by exploring the western portions of the Hazara-Kashmir-Syntaxis. We have used Google terrain imagery to map the evidence for active faulting that involves mapping of triangular facets, displaced and/or faulted topographic ridges, river terraces, alluvial fans and so on. The crosscutting relationships are used to date the faulting events where absolute dates are not available. Our results show that active tectonic deformation is not just limited to the previously mapped structures (e.g. the Kalabagh Fault, the Salt Range Thrust, the Mahesian Anticline, and the Jhelum Fault) but occurs on a broader deformation zone that is delimited by the Chaman fault system in the west, and the Jhelum Fault in the east. The deformation zone in 3D resembles a tectonically formed diamond shaped box that has Salt Range Thrust in front and the Main Boundary Fault at the back with sides delimited by the Chaman and the Jhelum fault systems. The earthquake centroid moment tensor data compliments our geomorphological work, and establishes that transpression is a dominant tectonic process that governs the western regions, which is in comparison to the east where transtension is the norm in the interior Himalayan with reverse and thrust faulting dominant in the frontal regions.
Contractile force assessment methods for in vitro skeletal muscle tissues
Authors: Vesga-Castro Camila , Aldazabal Javier , Vallejo-Illarramendi Ainara , Paredes Jacobo
Published: May 2022

Over the last few years, there has been growing interest in measuring the contractile force (CF) of engineered muscle tissues to evaluate their functionality. However, there are still no standards available for selecting the most suitable experimental platform, measuring system, culture protocol, or stimulation patterns. Consequently, the high variability of published data hinders any comparison between different studies. We have identified that cantilever deflection, post deflection, and force transducers are the most commonly used configurations for CF assessment in 2D and 3D models. Additionally, we have discussed the most relevant emerging technologies that would greatly complement CF evaluation with intracellular and localized analysis. This review provides a comprehensive analysis of the most significant advances in CF evaluation and its critical parameters. In order to compare contractile performance across experimental platforms, we have used the specific force (sF, kN/m2), CF normalized to the calculated cross-sectional area (CSA). However, this parameter presents a high variability throughout the different studies, which indicates the need to identify additional parameters and complementary analysis suitable for proper comparison. We propose that future contractility studies in skeletal muscle constructs report detailed information about construct size, contractile area, maturity level, sarcomere length, and, ideally, the tetanus-to-twitch ratio. These studies will hopefully shed light on the relative impact of these variables on muscle force performance of engineered muscle constructs. Prospective advances in muscle tissue engineering, particularly in muscle disease models, will require a joint effort to develop standardized methodologies for assessing CF of engineered muscle tissues.
A longitudinal inter-vehicle distance controller application for autonomous vehicle platoons
Authors: Gunagwera Alex , Zengin Aydin Tarik
Published: May 2022

Autonomous vehicle platoons are a promising solution to road safety, efficient road utilization, emission reduction, among other problems facing today’s transportation industry. However, consistently maintaining the desired inter-vehicle distance is one of the major problems facing autonomous vehicle platoons. In this study, we propose a proportional–integral–derivative (PID)-based cost-efficient algorithm to control the longitudinal inter-vehicle distance between successive members of an autonomous vehicle platoon. In our approach, calculations of the control algorithm are decentralized, and the data used in the control algorithm is obtained using one sensor per platoon member making the algorithm cost-efficient both computationally and financially. The proposed algorithm was implemented using the Robot Operating System (ROS) and applied to 3D vehicle models in simulations designed to mimic the natural environment in order to demonstrate and evaluate the suitability of the proposed algorithm for demanding and applicable scenarios. We performed meticulous simulations using the ROS framework in conjunction with the gazebo platform. In the proposed approach, the desired inter-vehicle distance between platoon members was successfully kept with a maximum absolute error of 5 m under any given scenario at any given time while maintaining platoon formation and ensuring that no collisions occur among platoon members.
Desinformación anticientífica sobre la COVID-19 difundida en Twitter en Hispanoamérica
Authors:   Universidad Rey Juan Carlos, García-Marín David , Merino-Ortego Marta ,   Universidad Nacional de Educación a Distancia, España
Published: May 2022

Este estudio profundiza en las características formales, los espacios de difusión y las narrativas anticientíficas relacionadas con el COVID-19 y su engagement en el contexto hispanoamericano. Este tipo de desinformación ha sido poco investigada, específicamente por parte de la comunidad científica en Iberoamérica, más centrada en el estudio de las fake news sobre esta crisis desde perspectivas más generales. Se analizaron 238 piezas desinformativas en dos fases: un estudio de todos los contenidos falsos anticientíficos verificados en 2020 y un análisis de los tuits más difundidos con el hashtag #plandemia. Los resultados cuantitativos fueron tratados con procedimientos estadísticos inferenciales mediante pruebas de chi cuadrado, Kruskal-Wallis, U de Mann-Whitney, estudios correlacionales y regresión lineal. Este trabajo avanza algunos de los patrones de la desinformación científica que pueden resultar útiles para futuras crisis sanitarias: la alta prevalencia del contenido completamente inventado, la relevancia de los elementos visuales (aunque no son factores predictores del engagement en este tipo de narrativas) y la creciente importancia de los servicios de mensajería instantánea como espacios de propagación. Asimismo, se discute el notable rol de los verificadores frente a la desinformación, que muestran eficacidad para desmontar los relatos negacionistas y conspirativos que circulan sobre la enfermedad y lograr una comunicación efectiva de la ciencia.
Worrisome Implications of Accidental Injection of Colourless Corrosive Chemicals Intraorally into Perioral Tissue Spaces: A Severe Negligence
Authors: Khandelwal Pulkit , Hajira Neha
Published: May 2022

During certain treatment procedures in a dental clinic, few colourless chemicals like Local Anaesthetics (LA), sodium hypochlorite, formalin, hydrogen peroxide, xylene, chloroform, etc., are often used simultaneously. Instead of LA, these chemicals may be accidentally injected in oral soft tissues due to casual handling. These accidental injections produce severe corrosive effects in and around perioral tissues and may lead to chemical necrotising cellulitis within 24 hours. Osteolytic changes of underlying bone and fatty infiltration with necrosis of the soft tissues can also occur. These events of accidental injection of such corrosive chemical solutions in patients during dental treatment may occur owing to the use of empty LA bottles for storage of these corrosive chemicals which can be easily mistaken for LA solution. Every solution has its indicated use in dentistry and treatment procedure. While performing any treatment procedure in dental clinic, utmost care and precautions must be taken to avoid any medical negligence in administering such corrosive chemicals intraorally which may make the patient’s life havoc because of hazardous complications in maxillofacial region. This paper reviews accidental intraoral injection of these colourless chemicals and also discusses the adverse effects, prevention and management of such inadvertent injections. Successful management includes cautious debridement and empirical drug therapy (antibiotics and analgesics).

Published: May 2022

Eutrophication, salinization, hypoxia, and toxic algae, among other environmental damages are costly consequences of agricultural drainage water (ADW), and therefore poses a threat to ecological biodiversity, food security and agriculture sustainability. This work aimed to assess the adsorption efficiency of rice husk (RH) modified by chemical and thermal treatments for sulphate minimization from ADW. RH obtained from a local rice mill was washed in distilled water, oven-dried at 105 ˚C for 24 h, milled and sieved into 0.3–1.18 mm particle sizes. The optimum condition for carbonization was determined by varying the temperature- 200, 300 and 400 ˚C and time- 1, 1.5, and 2 h, respectively. The RH was activated by chemical (H3PO4 and ZnCl2) and thermal treatment. Batch experiments were carried out varying temperature (40-60 °C), adsorption time (15–140 min) and adsorbent dose (1 and 2 g) in an ADW with known sulphate concentration, 30 mg/L. The carbonization yield at 400, 300 and 200 ˚C varies within 18.91- 27.48%, 27.39- 32.82 % and 81.94- 95.75% respectively. It was observed that the percentage of carbon converted into silica increases with burning time; hence, the optimum temperature of 350 ˚C for 2 h was used for carbonization. Also, sulphate adsorption rate increased with contact time and dosage suggesting that the process is controlled by surface and pore diffusion. Based on the temperature study, adsorption was favourable at lower temperatures. H3PO4 and ZnCl2 treated adsorbents have similar removal efficiency; however, ZnCl2 treated adsorbent has a higher efficiency due to its ability to enhance the stability and mesoporosity of carbonaceous material. Modified RH is a potential adsorbent that could be of noble use in ADW quality minimization. However, the huge gap between literature studies and field application needs to be bridged by good extension services and appropriate policy.

The present study was conducted in Punjab to analyse the socio- economic profile of 200 farmers using an interview schedule. The findings of the study revealed that large percentage of farmers belonged to general category and majority were nuclear having 2-5 members. Majority of farmers were cultivating between 5 to 15 acres of land. Largest percentage among these cultivated less than 5 acres. The owned cultivated land ownership of majority was less than 5 acres with negligible families owning more than 20 acres. More than fifty percent (56.5%) families leased in land for cultivation. Out of these, half of the sample families leased less than 5 acres of land and more than one fourth families (26.54%) between 5-10 acres of land. Farming was primary source of income for very large majority of the farmers. More than half of the farmers were engaged in some secondary occupation with highest percentage engaging in farm based entrepreneurship followed by farming and non-farm based business. Annual income of majority of farmers was upto three lakhs. Income was not significantly different in different zones which was highest in zone IV and least in zone V. Few of the farmers reported being a member of some organization.
The Effect of Earnings Management and Profitability on Stock Prices Future: Information Asymmetry as Moderating

Published: May 2022

Purpose: One of the most popular types of securities in the capital market is stock securities. Stocks that are considered good are stocks that are able to provide realized returns that are not too far from the expected returns, which are reflected in future stock prices. Through information asymmetry, it is expected to see the magnitude of the influence of earnings management on stock prices in the future. The purpose of this study is to examine the effect of earnings management on stock prices in the future with asymmetry as a moderating variable.

Methods: The method used in this study is a quantitative analysis method with cross-sectional data, using secondary data in the form of financial statements of consumption sector manufacturing companies listed on the Indonesia Stock Exchange (IDX) from 2015 to 2019, with analytical tools using SPSS.22

Findings: The higher the information asymmetry, the greater the bid-ask spread, in this case, the disclosure of earnings (ROA) in the financial statements is expected to reduce information asymmetry so that the bid-ask spread also decreases which leads to an increase in stock prices the future.

Novelty: The higher the information asymmetry, the greater the bid-ask spread, in this case, the disclosure of earnings (ROA) in the financial statements is expected to reduce information asymmetry so that the bid-ask spread also decreases which leads to an increase in stock prices the future.

This paper discusses the performance and efficiency analysis of selected private sector banks in the light of tough competition and technology up gradation. Right from the establishment of Royal Chartered bank, Indian banking sector has seen a magnanimous growth especially after independence. The nationalization of banks in 1969 and 1980 had added fuel to the growth. The New Economic policy, 1991 has totally changed the facets of the banking sector. The doors are open to the private and foreign banks to India and the services are scattered and spread to various areas like wealth management, insurance, mutual funds, forex trading, financial services etc apart from the primary objective of accepting deposits and lending loans. This research paper focuses on evaluation of the performance and efficiency analysis of selected private sector banks with respect to some of the key indicators such as Total deposits, Total advances, Total Assets, Net Profit & Non-Performing Assets of last 10 years. The absolute figures and the average annual growth rates (AAGR) were calculated for each indicator over a period of 10 years and accordingly the rankings were assigned based on performance and efficiency analysis. Key area findings of the research were found and so incorporated in the study. The research found that has been performing well among the given three banks when compared with other two banks.

Chemical fertilisers and insecticides have increased at an alarming rate in India since the green revolution. Excessive chemical use has a negative influence on the ecosystem, soil, human health, and Consumption of groundwater purity. To limit the usage of artificial fertilisers and pesticides in this situation, the Zero Budget Natural Farming technique was implemented. Agriculture is a significant industry in India. It is essential for the Indian economy's survival and expansion. The majority of farmers rely extensively on inorganic external chemical inputs like as fertilisers and pesticides, which pollute groundwater and other water-dependent ecosystems while also reducing soil fertility over time. The continued use of pesticides and chemicals poses a major threat to the health of Indian farmers.Zero-budget farming has the potential to significantly reduce production expenses. Mulching, soil protection measures, natural insecticides, and fertilisers are used by low-budget farmers. Jivamrita, Bijamrita, Acchadana (Mulching), and Whapasa are the four main pillars of natural farming on a low budget. Mulching, soil conservation measures, natural insecticides, and fertilisers are used by farmers on a low budget. The continual retention of crop wastes replenishes soil fertility and aids in soil health maintenance. Pest and disease management is an important part of zero-budget natural farming crop production methods. Under the conditions of climate change, achieving food security would necessitate a holistic system approach that incorporates natural agricultural principles for a sustainable agriculture.In this paper, we have discussed about the concept, need, benefits, major pillars, principles of ZBNF, opportunities and challenges of adopting ZBNF and the factors to scale up zero budget natural farming.

During the processing of fruits, large quantities of wastes are generated, these by-products contain large amounts of oil, starch and protein that can be exploited due to their good nutritional, technological, and functional properties. However, due to the presence of several antinutritional factors, such as polyphenolic compounds, phytic acid, cyanogenic glycoside and oxalates, the use of fruit wastes in human food is limited. The present investigation was aimed to study the effect of soaking and heating on antinutritional factors. It also examines the effect of substituting defatted apricot, peach, and mango seed kernel flours for wheat flour in various ratios (5, 10, and 15%) on the chemical composition, physical features, and sensory properties evaluation of biscuits. The results revealed a significant effect of soaking and heating on the antinutrients, detoxification led to a significant (p≤0.05) decrease in antinutritional factors with ratios 43.63-52.73% total phenols, 78.17-86.16% tannins, 45.92-54.34% phytic acid and 40.42-44.70% oxalates, along with the complete removal (100%) of hydrocyanic acid (HCN). Wheat biscuit contained 3.20% moisture, 6.31% protein, 15.46% fat, 0.64% crude fiber, 1.25% ash and 76.33% carbohydrate. Highly acceptable biscuits could be obtained by incorporating 5% of defatted apricot, peach and mango kernel flours in the wheat biscuits formulation. As a by-product, apricot, peach and mango kernels offer an exciting potential as a food ingredient permitting to enrich biscuits and enlarge the food base for consumers.
