From Propagation to Field: Influence of Tray Design on Tree Seedling Quality and Performance1
Authors: McGrath Darby , Henry Jason , Munroe Ryan , Williams Charlene
Published: March 2021

This study evaluated the effects of low, moderate and high substrate exposure air-pruning propagation trays on eastern cottonwood (Populus deltoides W. Bartram ex Marshall ssp. deltoides) and black cherry (Prunus serotina Ehrh.) seedling root system quality and overall performance. Root system quality was characterized primarily by proportion of coarse root defects within the container imprint. Seedlings were evaluated after a nearly four-month commercial greenhouse production phase and one year after transplanting into a nursery field. Above and below-ground growth were measured at both time points. Proportions of coarse root defects, indicating degree of root deflection in container production, were persistent between greenhouse and field production phases. The Open (high substrate exposure) tray produced seedlings with roughly three times less deflected coarse root weight compared to the Closed Wall (low substrate exposure) tray for both species in both production phases. At neither production phase were there significant differences in above-ground growth among trays. This corroborates findings from other research studies that have found that variable root system quality does not always result in above-ground growth differences; and that when it does, differences in growth may take several years to manifest.

Index words:, tree seedling quality, root defects, transplant performance, above-ground growth.

Species used in this study: eastern cottonwood (Populus deltoides W. Bartram ex Marshall ssp. deltoides), black cherry (Prunus serotina Ehrh.).
The importance of evil for the understanding of Freedom and its role in the emergence of the personality in Friedrich Schelling’s Freiheitsschrift
Authors: Karakasis Georgios
Published: March 2021

El objetivo de este artículo es presentar la idea de emergencia del ser humano ofrecida por Schelling en su Tratado de la esencia de la libertad humana. Se discurre sobre como el ser humano, alzándose desde el Fundamento de Dios, desde el primer momento se halla estrechamente entrelazado en la interacción entre el Fundamento y la Existencia de Dios, erigiéndose así como único ser de la Creación que posee la posibilidad esencial de elegir libremente el objeto de su voluntad. Además, el texto trata de mostrar que el mal es una condición necesaria tanto para que el ser humano sea capaz de ser libre como para moldear su personalidad.
Nvidia's Stock Returns Prediction Using Machine Learning Techniques for Time Series Forecasting Problem
Authors: Chlebus Marcin , Dyczko Michał , Woźniak Michał
Published: March 2021

Statistical learning models have profoundly changed the rules of trading on the stock exchange. Quantitative analysts try to utilise them predict potential profits and risks in a better manner. However, the available studies are mostly focused on testing the increasingly complex machine learning models on a selected sample of stocks, indexes etc. without a thorough understanding and consideration of their economic environment. Therefore, the goal of the article is to create an effective forecasting machine learning model of daily stock returns for a preselected company characterised by a wide portfolio of strategic branches influencing its valuation. We use Nvidia Corporation stock covering the period from 07/2012 to 12/2018 and apply various econometric and machine learning models, considering a diverse group of exogenous features, to analyse the research problem. The results suggest that it is possible to develop predictive machine learning models of Nvidia stock returns (based on many independent environmental variables) which outperform both simple naïve and econometric models. Our contribution to literature is twofold. First, we provide an added value to the strand of literature on the choice of model class to the stock returns prediction problem. Second, our study contributes to the thread of selecting exogenous variables and the need for their stationarity in the case of time series models.
The Effects of Self-Esteem, God Image, and Gender on Coping Methods
Authors: Downing Jessica , Sinisi Christina , Foster Rebecca
Published: March 2021

Factors such as self-esteem, God image, and gender can affect the way an individual copes with everyday stressors. Past research has shown high self-esteem to have a significant relationship with problem-focused coping, whereas low self-esteem produced mixed results between avoidance and emotion-focused coping (Chapman & Mullis, 1999). Regarding God image, a sense of God’s presence contributed to a healthy, positive coping strategy for individuals facing difficulties (Aten et al., 2008). Studies examining the influence of gender on coping methods have generated mixed results (Cecen, 2008). The present study examined the impact of gender, self-esteem, and God image on coping methods. Participants (N = 368) completed a survey online. Results showed that gender, self-esteem, and perceiving God as Present, Benevolent, Provident, and Challenging were significant predictors of utilizing problem-focused coping, F(8, 344) = 8.27, p < .001. Gender and viewing God as Benevolent and Accepting had significant effects on emotion-focused coping, F(8, 344) = 3.44, p = .001. Lastly, perceiving God as less Accepting was a significant predictor of using avoidance to cope, F(8, 344) = 6.44, p < .001. In conclusion, given the potential impact of God image on coping, clinicians working with individuals who espouse a faith could incorporate the clients’ images of God into treatment and examine how these factors impact their ability to cope with life stressors.
The impact of green taxation policy on China's economic growth
Authors: ZAERNYUK Viktor M. , CHANG Chi
Published: March 2021

Subject. This article highlights the need to coordinate actions on economic growth and environmental protection in order to achieve the optimal situation in the development of the Chinese economy.
Objectives. The article aims to consider methodological tools for assessing the impact of green tax policies on economic growth by building a dynamic panel model of the quantity and quality of economic growth and green tax policy.
Methods. For the study, we analyzed the economic literature and empirical research on environmental taxation, environment and sustainable economic development in existing theories of economic growth. The Cobb–Douglas production function and Barla and Perelman's research ideas were also used.
Results. The article finds that the degree of environmentalization of China's tax system remains low. Both constrained and extended green tax policies have deterrent effects on economic growth, and environmental decentralization does not contribute to the sustainable development of the economy, while weakening this adverse effect.
Conclusions. China's tax reform needs to be improved to meet the real needs of green advancement. It is important to accelerate the transition from a double taxation system to a triple taxation system, which will create a multi-level and perfect system of green taxation.
Applying net income-based multipliers in the valuation of oil and gas corporations
Authors: SHIMKO Oleg V.
Published: March 2021

Subject. This article explores the ratios of the company's market capitalization to the net income of shareholders of the twenty five leading public oil and gas companies between 2008 and 2018.
Objectives. The article aims to identify key trends in the changes in the values of market-capitalization-to-shareholders'-net-income ratios of the largest public oil and gas companies, identify the factors that have caused these changes, and establish the applicability of these multipliers to estimate the value of the business within the oil and gas industry.
Methods. For the study, I used comparative, and financial and economic analyses, and generalization of materials of the companies' consolidated financial statements.
Results. The article establishes that the multipliers studied based on the net profit of shareholders are of little use for assessing the value of oil and gas companies due to the volatility of oil prices.
Conclusions. To apply the multipliers based on net profit is very difficult in the face of declining profitability and increasing debt burden in the stock exchange sector of the global oil and gas industry.
Towards an archaeology of rubber
Authors: Silva Alves Muniz Tiago
Published: March 2021

This article aims to address the impacts of rubber via historical and contemporary archaeology of the Amazon. Through an “archaeology of rubber” a notion of modernity is examined here. From the creation of rubber gloves to snow boots and tires, rubber has allowed humans to expand their interactions with the environment. As these interactions expanded, the consolidation of the Industrial Revolution and Occidentalism entangled actors in a complex web of meanings, becomings and agencies in opposition to local knowledge. Through a plural and multispecies approach, this article places the study of rubber’s materiality in the field of the archaeology of capitalism and modernity. Also, through oral history, deep archival research and public archaeology, local ontologies and materialities offer contemporary archaeology a more elastic view, aimed at widening perceptions of a global story.
Quantum interpolation of polynomials
Authors: Kane Daniel M. , Kutin Samuel A.
Published: March 2021

Can a quantum computer efficiently interpolate polynomials? We consider black-box algorithms that seek to learn information about a polynomial $f$ from input/output pairs $(x_i, f(x_i))$. We define a more general class of \emph{$(d,S)$-independent} function properties, where, outside of a set $S$ of exceptions, knowing $d$ input values does not help one predict the answer. There are essentially two strategies to computing such a function: query $d+1$ random input values, or search for one of the $|S|$ exceptions. We show that, up to constant factors, we cannot beat these two approaches.
Universal quantum computation and leakage reduction in the 3-Qubit decoherence free subsystem
Authors: Fong Bryan H. , Wandzura Stephen M.
Published: March 2021

We describe exchange-only universal quantum computation and leakage reduction in the 3-qubit decoherence free subsystem (DFS). We discuss the angular momentum structure of the DFS, the proper forms for the DFS CNOT and leakage reduction operators in the total angular momentum basis, and new exchange-only pulse sequences for the CNOT and leakage reduction operators. Our new DFS CNOT sequence requires 22 pulses in 13 time steps. The DFS leakage reduction sequence, the first explicit leakage reduction sequence of its kind, requires 30 pulses in 20 time steps. Although the search for sequences was performed numerically using a genetic algorithm, the solutions presented here are exact, with closed-form expressions.

PieParty: visualizing cells from scRNA-seq data as pie charts
Authors: Kurtenbach Stefan , Dollar James J , Cruz Anthony M , Durante Michael A , Decatur Christina L , Harbour J William
Published: March 2021

Single-cell RNA sequencing (scRNA-seq) has been a transformative technology in many research fields. Dimensional reduction techniques such as UMAP and tSNE are used to visualize scRNA-seq data in two or three dimensions for cells to be clustered in biologically meaningful ways. Subsequently, gene expression is frequently mapped onto these plots to show the distribution of gene expression across the plots, for instance to distinguish cell types. However, plotting each cell with only a single color leads to repetitive and unintuitive representations. Here, we present PieParty, which allows scRNA-seq data to be plotted such that every cell is represented as a pie chart, and every slice in the pie charts corresponds to the gene expression of a single gene. This allows for the simultaneous visualization of the expression of multiple genes and gene networks. The resulting figures are information dense, space efficient, and highly intuitive. PieParty is publicly available on GitHub at https://github.com/harbourlab/PieParty.

CHECKING THE ASSOCIATION OF FIVE SNP WITH UNVALVED ATRIAL FIBRILLATION IN PATIENTS WITH ACUTE CORONARY SYNDROME
Authors: N.G. Lozhkina , A.A. Gurazheva , V.N. Maksimov
Published: March 2021

Вackground. It is known that 5–21% of patients with acute coronary syndrome (ACS) develop atrial fibrillation (AF), which entails an increased risk of recurrence of myocardial infarction, heart failure, and increased mortality. The genetic predisposition to AF has been actively studied in recent years, but the data on the association of certain single nucleotide polymorphisms (SNPs) in the development of AF are contradictory, which determines the relevance of this study.
Purpose of the study. To study five SNPs for associations with the development of non-valvular atrial fibrillation in patients with acute coronary syndrome
Patient Characterization and Research Methods. The study included female and male patients not younger than 18 years old with ACS and AF (n = 133) and ACS without AF (n = 133) ACS was diagnosed according to the criteria of the European Society of Cardiology (2015; 2017). The study was approved by the Ethics Committee (Minutes No. 102 dated November 24, 2017). The observation period was 12 months. In addition to the standard examination, all patients underwent a SNP study: rs6795970 (Scn10a), rs2200733 (4th stage), rs11556924 (ZC3HC1), rs599839 (PSRC1), rs10824026 (10th stage). Statistical analysis was performed using Statistica 12.1 StatSoft.
Results. The results of the rs599839 study showed that the GG genotype was significantly less common in the ACS + AF group compared to the ACS group without AF (OR 0.11 CI 95% 0.01; 0.86 p = 0.0163). A reliable connection was lost when divided by sex and by age (older and younger than 55). Allele G rs599839 significantly correlates with AF (p = 0.0043; OR 1.56). The T allele rs11556924 is highly reliably associated with a predisposition to atrial fibrillation (p = 0.0043; OR 1.93). Genotype GG rs10824026 is conditionally protective in terms of the risk of AF in patients with ACS. For rs6795970 (p = 0.290) and rs2200733 (p = 0.30), there were no statistically significant differences between the study groups.
Conclusion. The study verified the association of rs6795970 (Scn10a), rs2200733, rs11556924, rs599839, rs10824026 with AF associated with ACS. The genotypes GG rs599839 and GG rs10824026 were found to be conditionally protective in relation to the risk of AF in patients with ACS.
Two Outstanding Aluminum Pedestrian Bridges in a National Historic Site
Authors: Cusson Benoit
Published: March 2021

In 2017, WSP undertook the challenge of designing two non-conventional aluminum multifunctional walkways for Parks Canada at the Lachine Canal National Historic Site. The designer retained the geometry of the early 19thrailway bridges to recall the rich heritage of the industrial era that marked the site. Choosing aluminum for the structures emphasizes Parks Canada’s vision: walking towards the future and using innovative, maintenance-free materials. The 27 m x 4.5 m pony truss aluminum structures are completely welded, thus requiring no assembly on site. This is a feat given the constraints of this material. With nearly 5,000 pedestrian and cyclist crossings per day, the works were planned to limit the duration of the building site to only three weeks.

This article focuses on the design of the non-redundant chords of the structures and the vibration issues due to pedestrian crossing. Explanations are provided regarding how the designer applied the provisions that have mainly been prepared for steel and concrete structures to aluminum structures. In the context of a non- redundant single span, it was still possible to obtain a nearly constant demand over capacity ratio for the compressed top chord over its entire length. Moreover, it describes how it is possible to quantify the performance of a footbridge with regards to vibration behavior at the serviceability limit state.
Test and Numerical Study on the Seismic Performance of A Cable Restrainer for Girder Bridges
Authors: Gu Yitong , Yuan Wancheng , Dang Xinzhi
Published: March 2021

In China, most of the support systems applied by short/medium span bridges are elastomeric pad bearings (EPBs). This type of support system has no reliable connections between bearings and girders as well as bearings and piers, which will cause structural damages due to large lateral displacement of bearings under earthquakes. The restrainers used currently could restrict the deformation of bridges under normal service conditions and could only restrict unidirectional displacement. Considering the disadvantages of these restrainers, a new restrainer called Connected Cable Restrainer (CCR), which can be used in short/medium span bridges supported by EPBs, is developed in this paper. The design principle, basic configuration, isolation mechanism and the design method of CCR are introduced. A pseudo static test to study the seismic performance of CCR is conducted. Seismic responses of a 3-span continuous girder bridge with CCR are simulated using OpenSees platform and parametric analyses of the two main parameters, lateral restraining displacement and restraining stiffness, are also carried out. Results show that the deformation of bridges under normal service conditions would not be restrained using CCR and the displacement responses can be mitigated effectively by using CCR through parameter optimization.
Measured earth pressures behind an integral bridge abutment
Authors: Skorpen Sarah A. , Kearsley Elsabe P. , Kruger Edwin J.
Published: March 2021

Integral bridges are preferred by bridge authorities and road agencies because they provide a simpler form of construction, with reduced maintenance costs as a result of the elimination of bridge bearings and joints. This simpler construction brings with it design challenges as both the structure and the adjacent fill are constantly moving. Thermal expansion and contraction of the deck causes the abutments to move, leading to changes in pressure in the earth fill behind the abutment. The soil adjacent to the abutment accommodates the cyclic deck expansion and contraction caused by changes in bridge deck temperature. This results in an increase in the stiffness of the fill due to densification. Even if the fill is placed in a loose condition, it will be densified during the lifetime of the structure. The build‐up of pressure depends on the nature of the fill behind the abutment and on the type of abutment. Stiff clays show a relatively low build‐up of lateral stress however sand stresses can increase beyond at‐rest pressure and approach full passive pressures. Much of the research on this type of soil structure action has been done in the laboratory with limit conclusive field testing.

In this paper earth pressures measured over a 2 year period on a 90m long fully integral bridge are summarized and discussed in relation to measured changes in effective bridge temperature as well as the abutment movement, thus testing the hypothesis that when more strain (i.e. a longer bridge and/or increase in the change in effective bridge temperature) is imparted to the soil, more granular flow occurs, resulting not only in more rapid stress escalation, but also in higher earth pressures.
Structural response reconstruction using inclinometer and velocimeter
Authors: Li Yixian , Sun Limin , Zhang Wei
Published: March 2021

This paper proposes a structural dynamic response reconstruction algorithm using inclinometer and velocimeter, combining in-situ measured data with finite element model. Using a small number of inclination and velocity data, the dynamic deflection, rotation, and strain at any position of a structure can be estimated. Firstly, static structural deformation estimation method is introduced as the base. The key content is to solve an underdetermined static equation using partial least square regression and calculate equivalent nodal force. By rewriting dynamic balance equation into state space, an equivalent static balance equation is obtained. Use partial least square regression to solve this equation and compute time histogram of equivalent nodal force, in which dynamic distortion exists. Accordingly, a frequency response-based time interval correction method is proposed to correct the dynamic distortion and is validated to be effective. Finally, numerical simulation is adopted to validate accuracy and robustness of the algorithm through changing parameters including sampling time interval, input frequency components, model parameters and introducing measurement noise. All results have demonstrated that the algorithm is of good adaptability to various changes and maintains high accuracy.

Published: March 2021

The symptoms of overdue maintenance and underinvestment in historic infrastructure are ever-present in our society (rated with D+ by American Society of Civil Engineers, ASCE). To ensure the safety of historic and existing structures, on-site inspections are required, and structural health monitoring systems are frequently adopted. While these methods capture large amounts of information about a structure, there is not a comprehensive method for integrating these diverse datasets into a single, intuitive environment for both on- and off-site usage. The objective of this work is to explore two different methodologies for integrating datasets derived from the built environment. The first method, Virtual tours and informational modeling (VTIM), uses spherical panoramas to capture the interior and exterior of the built environment as well as enables a user to access data through on-click conditionals attached to the panoramas. The second method, Image-based documentation and augmented reality (IBDAR), uses a sparse point cloud to capture the built environment for on-site viewing and additionally stores an image at every annotation location to facilitate off-site viewing. Both methods are applied to case studies including a masonry lighthouse in Charleston, SC and a pedestrian bridge in Princeton, NJ. The advantages and disadvantages of each approach are discussed as well as steps for future work are briefly outlined.
Understanding cracks in historic structures: Quantitative assessment though numerical simulation and manifold learning

Published: March 2021

For projects focused on restoration and strengthening of historic structures, information about the origins, magnitude, and stability implications of damage to a structure are required. The objective of this work is to create a novel methodology for understanding the causes of cracks in masonry structures and the resulting effects on global stability. Using Distinct Element Modeling (DEM), the crack patterns of a building can be simulated for a combination of loading scenarios. The results of this method are benchmarked against experimental results and applied to three case studies. The limitations of current physics-based approaches are discussed and a solution using manifold learning is outlined. Manifold learning can be applied to ensembles of crack patterns observed on real or simulated structures to infer damage pathways when the mechanism is unknown. This technique uses a perceptual hashing of the crack patterns to produce an affinity matrix, which is then analyzed by spectral methods to learn a small set of parameters which can describe the ensemble. Because the affinity is derived from a sparse perceptual hash, these descriptors can then be used to interrogate the manifold via a "lifting" operation which reveals the dominant failure modes in the sample.
Determination of Basic Wind Velocity for Wind Load-Governed Limit State
Authors: Kim Ji Hyeon , Lee Hae-Sung
Published: March 2021

This paper proposes a general procedure for evaluating a nominal value of wind velocity for a wind load- governed limit state to secure a target reliability index during the design life of a structure. The nominal value of wind velocity, referred to as a basic wind velocity, and wind load factor should be determined so that the factored wind load effect secures a target reliability index for a wind load-governed limit state. In this study, the analytical form of the return period of the basic wind velocity is expressed as a function of the target reliability index, wind load factor, and statistical parameters of wind pressure, which are derived as linear functions of the coefficient of wind velocity. The proposed approach is applied to the Korean Highway Bridge Design Code-Cable supported Bridge, which specifies the design life of a structure as 100- and 200-year.
Fresh and Mechanical Properties of Zero-Cement One-Part Geopolymer Mortar and Concrete
Authors: Islam Md. Mashfiqul , Gheni Ahmed A. , ElGawady Mohamed A.
Published: March 2021

The era of research on fly ash based Zero-Cement (ZC) containing alkali activated geopolymer mortar and concrete has already begun. By replacing 100% of cement which is the higher carbon footprint material and also by maintaining a steady level on eco-system without causing severe environmental damage or exhausting natural resources, geopolymer technology is on the way to be the most popular sustainable construction material. However, the mixing mechanism of geopolymer is very difficult using the liquid alkaline activators which are hazardous as well as difficult to handle in large construction works at sites. As a result, the development of producing one-part geopolymer or “just add water” process similar to ordinary

Portland cement (OPC) construction, is necessary for the promotion of this green and sustainable

construction material to the society. To this end, two different sources of Class C fly ash (FA) from Missouri State, USA are used in this study to investigate the mechanical as well as the fresh properties of ZC mortar and concrete. In this study, the dry sodium hydroxide (SH) pellets and sodium silicate (SS) powder are used as solid alkaline activators. Three different curing systems, e.g. ambient, oven and steam curing are employed in this study and corresponding strength gains are evaluated. A significant enhancement of the compressive strength was achieved by the addition of 1.9 mass% of sucrose (sugar) with respect to FA in the mix after curing at the elevated temperature.

Background

Several clinical trials have assessed the protective potential of chloroquine and hydroxychloroquine. Chronic exposure to such drugs might lower the risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or severe coronavirus disease (COVID-19).

Aim

To assess COVID-19 incidence and risk of hospitalisation in a cohort of patients chronically taking chloroquine/hydroxychloroquine.

Methods

We used linked health administration databases to follow a cohort of patients with chronic prescription of hydroxychloroquine/chloroquine and a control cohort matched by age, sex and primary care service area, between 1 January and 30 April 2020. COVID-19 cases were identified using International Classification of Diseases 10 codes.

Results

We analysed a cohort of 6,746 patients (80% female) with active prescriptions for hydroxychloroquine/chloroquine, and 13,492 controls. During follow-up, there were 97 (1.4%) COVID-19 cases in the exposed cohort and 183 (1.4%) among controls. The incidence rate was very similar between the two groups (12.05 vs 11.35 cases/100,000 person-days). The exposed cohort was not at lower risk of infection compared with controls (hazard ratio (HR): 1.08; 95% confidence interval (CI): 0.83–1.44; p = 0.50). Forty cases (0.6%) were admitted to hospital in the exposed cohort and 50 (0.4%) in the control cohort, suggesting a higher hospitalisation rate in the former, though differences were not confirmed after adjustment (HR: 1·46; 95% CI: 0.91–2.34; p = 0.10).

Conclusions

Patients chronically exposed to chloroquine/hydroxychloroquine did not differ in risk of COVID-19 nor hospitalisation, compared with controls. As controls were mainly female, findings might not be generalisable to a male population.
Becoming a posthuman systemic nomad. Part II: Systemic Nomads. An Ecosophy
Authors: Van Hennik Robert
Published: March 2021

In the second part of the text “Becoming a posthuman systemic nomad”, I suggest ways in which systemic practitioners may become systemic nomads, reintegrating cybernetics and social constructionism and taking a new-materialist perspective on life. Systemic therapists may become “post human systemic nomads”, navigating and systemically learning in complex adaptive systems, in which we are relational responsible to all human and non-human actors in the networks that we produce and that we are produced by. Inspired by the philosophy of Deleuze and Guattari I made three cartographies for us, systemic nomads, navigating complexity in multi-actor systems. Systemic practitioners (from a new-materialist perspective) can co-create better ecological worlds if we are conscious of the effects of our actions in interdependent relationships with all actors in life, when – as nomads – we display systemic sensibility or intelligence (Senge, 2006) within systems of multi-actors.
 
Abstract (Dutch)
 
In dit tweede deel van de tekst “Becoming a posthuman systemic nomad” beschrijf ik hoe systeemtherapeuten en consulenten “systemische nomaden” kunnen worden door in hun denken en doen inspiraties uit de cybernetica, het sociaal constructionisme en het nieuw-materialisme te integreren.  Systeemtherapeuten en ‘systemisch’ consulenten, die “systemische nomaden” worden, navigeren en leren navigeren in complex adaptieve multi-actor systemen. Zij ervaren een ‘relationele verantwoordelijkheid’ naar zowel humane als niet-humane (dingen, dieren, planten) actoren in de netwerken waartoe zij betekenisvol bijdragen, waarvan zij om betekenisvol voort te bestaan afhankelijk zijn. “Systemische nomaden”, bewust van de inter-afhankelijkheid tussen alle humane en niet-humane deelnemers in het multi-actor netwerk, kunnen mogelijk bijdragen in de co-creatie van betere ecologisch afgestemde leefwerelden. Geïnspireerd door de filosofie van Deleuze en Guattari maakte ik drie cartografieën die ons in dit proces van navigeren en leren navigeren kunnen helpen.

Gems are well-compressed small pieces found in mineral deposits found inside earth. Pearls and amber are notable exceptions in that they are formed from organic materials. Most of the gemstones are crystalline. A crystalline mineral is formed by a distinct 3-dimensional atom and this is a unique characteristic of gemstones. They possess color, hardness, aesthetic beauty, clarity and they can be cut to give sparkle.According to David Marcum’s remarks in his book “The Dow Jones Irwin Guide to Fine Gems and Jewelry”:

PSYCHOLOGICAL EFFECTS OF COLORS ON HUMAN LIFE
Authors: Awasthi Bindu
Published: March 2021

Everything that exists in this world, which is visible, has its own color. Whether it belongs to space, planets, constellations, animals found on earth, birds, trees, rivers, humans, man-made objects etc., all things are independent of their existence due to the many colors. Those people who are lucky have a sense of varna. The reason for the sense of varna is we feel the beauty of this world.Varna realization happens only in the presence of light. Varna is the quality of light. "Physiology scholars state that light enters the eyes through the pupils." Stops directly on the back of the eye. There are two types of fibers on the retina called 'Rhodus' and Coens which are related to the vision veins. Through the nerves, it has a direct effect on our brain. Therefore, the color of day and night appears white and black. Color originates from light. Sun is the biggest form of light. The kind of object that is visible by the influence of the Sun is the same and as soon as the light is lost the object is of any type, black is visible only.

Published: March 2021

Depiction of murals in the caves of Anjanta has been made from the period of 200 BC to 620 AD, after such a long interval, the character beauty and salt of some of the pictures of the paintings have decreased, yet till date the aura of the paintings of Ajanta has not faded. . In the paintings of Ajanta, beautiful characters are seen here and there is vikhari. Although the brightness of these paintings has faded enough, the colors appear to be life-threatening. The shiny bottom, green and purple color still glows in its former aura. The colors of the body and the clothes are lavish and consistent, except for some early paintings of Ajanta, in the sixteenth and seventeenth caves, the painters of Ajanta have shown a tendency to draw figures in light letters on the dark background, but on the other hand dark shapes on the dark background. The tendency to make K is also seen which is similar to the Venetian-painting style of Europe. The painter was very conscious to attract the attention of the viewer to the picture, due to this he has used black color in the hair of human figures, which has increased the form and elegance and produced the desired effect.

अंजन्ता की गुफाओं मे भिति चित्रण 200 ई0 पू0 से लेकर 620 ई0 तक के समय तक बनायी गयी है इतने लम्बे समय अन्तराल के बाद कुछ भिति चित्रों के वर्ण सौष्ठव तथा लवण्य कम हुये है फिर भी आज तक अजन्ता के चित्रों की आभा फीकी नही पडी है। अजन्ता के चित्रों में सुन्दर वर्ण छटा यत्र-तत्र विखरी दिखाई पडती है। यद्यपि इन चित्रों की चमक पर्याप्त धूमिल पड चुकी है तथापि रंग जानदार प्रतीत होते है। चमकदार नीचे, हरे तथा बैगनी रंग अपनी पूर्व आभा में आज भी जगमगाते है। शरीर तथा कपडों का रंग लावण्य युक्त और संगत हैं अजन्ता के कुछ आरम्भिक चित्रों को छोडकर सोलहवीं तथा सत्रहवी गुफा में अजन्ता के चित्रकारों ने गहरी पृष्ठ भूमि पर हल्के वर्ण विधान में आकृतिया बनाने की प्रवृति दिखाई है, परन्तु दूसरी ओर हल्की पृष्ठ भूमि पर गहरी आकृतियों के बनाने के प्रवृति भी दिखाई पडती है जो यूरोप की वेनिस-चित्रकला शैली के समान है। चित्रकार दर्शक के ध्यान को चित्र की ओर आकृष्ट करने के लिये बहुत जागरूक रहा, इस कारण उसने मानवाकृतियों के बालों में काले रंग का प्रयोग किया है, जिससे रूप और लावण्य की वृद्धि हुई है और इच्छित प्रभाव उत्पन्न हो गया है।
COLORS IN MEDIEVAL BOOK PICTURES AND MINIATURES
Authors: Kumar Tiwari Pawanendra
Published: March 2021

In medieval India, colors for drawing were obtained from a variety of substances such as minerals, compounds or natural salts. Some colors were derived from natural materials such as plant biomass. For example, neem and wormwood etc. were used in large scale not only in pictures but also in writing. Similarly, because of red ink written in silver and gold, Swanakshari Shetakshari was named. Red ink was used to draw margins at the end of the prominence, in the lines, in the instruments, etc. Books written with gold and silver powder were more expendable and they had more sense of grandeur. It was also relatively difficult to write the letters of silver and gold and in reading it there was a lot of emphasis on the eyes. Most of the mineral colors have been used in the West Indian painting style. These were finely powdered and brought into color. The natural state of the dyes was impure, so it was purified by dissolving it in water. Heavy impurities used to sit at the bottom and the top water was drained and separated. This process was repeated many times and color refinement was used to dry it and used it for illustration. This action was called color washing.

मध्यकालीन भारत में चित्रण के लिए रंग कई प्रकार के पदार्थो जैसे खनिजों योगिको अथवा प्राकृतिक लवणों से प्राप्त किये जाते थे। कुछ रंग प्राकृतिक वस्तुओं जैसे वनस्पति जैव पदार्थो से प्राप्त किये जाते थे। उदाहरण के लिए नीम तथा कृमिदाना आदि काजल का प्रयोग न केवल चित्रो में बल्कि लेखन कार्य में भी बडे पैमाने पर हुआ। इसी प्रकार लाल स्याही चाँँदी तथा सोने में लिखा होने के कारण स्वणाक्षरी शेत्याक्षरी नाम दिया गया । लाल स्याही का प्रयोग अहमायो के अन्त में हाशिये खीचने में वृन्तों रेखाओं यंत्रों आदि में हुआ। स्वर्ण रजत चूर्ण से लिखी जाने वाली पुस्तके अधिक व्यय-साध्य थी उनमें वैभव-प्रदर्शन की भावना अधिक होती थी। चाँदी तथा स्वर्ण के अक्षरों को लिखना भी अपेक्षाकृत कठिन होता था तथा उसको पढने में भी आखो पर अधिक जोर पडता था। पश्चिम भारतीय चित्र-शैली में अधिकतर खनिज रंगों का प्रयोग किया गया है। इन्हें बारीक चूर्ण के रूप में लाकर रंग बनाया जाता था। रंगो की प्राकृतिक अवस्था अशुद्ध होती थी अतः उसको पानी में घोलकर निथारकर शुद्ध किया जाता था। भारी अशुद्धियाँ नीचे बैठ जाती थी तथा ऊपर का पानी निथारकर पृथक् कर लिया जाता था। इस क्रिया को कई बार दोहराकर रंग का शोधन किया जाता था इसे सुखाकर चित्रण-कार्य में प्रयुक्त करते थे। इस क्रिया को रंग धोना कहते थे।
