Year: 2021

description: Panchagavya is a combined five products of cow (viz., milk, urine, dung, curd, and ghee) used as ancient Indian traditional medicine. And also known as Cowpathy, treating diseases using cow products. Cowpathy (Panchagavya) therapy is an Indian ancient concept in Ayurveda that is concerned with using the components of five cow products for treating various body disorders. The components are obtained from Gas chromatography – Mass spectroscopy analysis. The database was obtained from web sources to identify the components. After analysis of Panchagavya on Gas chromatography – Mass spectroscopy, a total of ten constituents were identified. The antibacterial activity of Panchagavya against two Gram-positive (Staphylococcus aureus and Streptococcus pyogens) and two Gram-negative bacteria (E. coli and Klebsiella pneumoniae) were analyzed. Panchagavya shows good inhibitory properties on Staphylococcus aureus (20 mm) other than all bacteria. The present study showed the components present in Panchagavya and antimicrobial activities.

description: This paper deals with some thermodynamical aspects of Lorentzian wormholes, including the formulation of the three main laws and the consideration of a possible thermal emission made up of some sort of phantom radiation coming out from the wormhole at a negative temperature. In order for these topics to be consistently developed we have used a 2+2 formalism first advanced by Hayward for spherically symmetric space-times, where a generalized surface gravity is defined on the trapping horizon. Our results generalize still further those of the already generalized gravitational thermodynamics.

Publisher: name: Zenodo

description: Fishes live in aquatic environment where they continuously encounter many pathogenic, opportunistic, and non-pathogenic microbes. The first line of defense against these microbes is the epidermis. The epidermis contains mucus-producing cells such as goblet cells or mucus cells, sacciform cells, pavement cells, etc., producing epidermal mucus. Epidermal mucus is a mixture of mucin, water, glycoproteins and other bioactive macromolecules. Bioactive macromolecules and glycoproteins of mucus provide antiviral, antibacterial, and antifungal properties to the mucus. Channa punctatus is a member of Channidae family which means they can breathe air through their gills, and they are commonly found on swamps and brackish water. Their habitat triggers some immune response which causes production of more antimicrobial proteins on their surface, where their air breathing nature supports the extraction of mucus outside water without killing them. Our study observed the antimicrobial activity of epidermal mucus of “Channa punctatus” against eight microbes that are either pathogenic or opportunistic to humans. Fish was procured from the local fish market and acclimatized at room temperature for 48h. Further it was starved for 24h before collecting mucus and mucus was extracted on 10% acetic acid solvent. Antagonistic activity test was performed to observe the antimicrobial activity in terms of zone of inhibition (ZOI). Maximum activity was observed against Staphylococcus aureus, whereas minimum action against Bacillus licheniformis. The concentration of antimicrobial proteins in epidermal mucus was 0.25mg/ml in Channa punctatus determined by Bradford assay using BSA as standard plot.

description: The chemical composition of the gas in galaxies versus cosmic time provides a very important tool for understanding galaxy evolution. Although there are many studies at high redshift, they are rather scarce at lower redshifts. However, low redshift studies can provide important clues about the evolution of galaxies, furnishing the required link between local and high redshift universe. In this work we focus on the metallicity of the gas of star-forming galaxies at low redshift, looking for signs of chemical evolution. To analyze the metallicity contents star-forming galaxies of similar luminosities and masses at different redshifts. With this purpose, we present a study of the metallicity of relatively massive (log(M_star/M_sun)>10.5) star forming galaxies from SDSS--DR5 (Sloan Digital Sky Survey--Data Release 5), using different redshift intervals from 0.04 to 0.4. We used data processed with the STARLIGHT spectral synthesis code, correcting the fluxes for dust extinction, estimating metallicities using the R_23 method, and segregating the samples with respect to the value of the [NII]6583/[OII]3727 line ratio in order to break the R_23 degeneracy selecting the upper branch. We analyze the luminosity and mass-metallicity relations, and the effect of the Sloan fiber diameter looking for possible biases. By dividing our redshift samples in intervals of similar magnitude and comparing them, significant signs of metallicity evolution are found. Metallicity correlates inversely with redshift: from redshift 0 to 0.4 a decrement of ~0.1 dex in 12+log(O/H) is found.

title: The role of risk in investment behaviour and the manifestation of behavioural biases by individual investors
Creators: name: Suhobokov, Alexander

Year: 2021
Subjects: subject: behavioural finance, individual investors, individual decision making, risk-as-feelings.

description: I use a novel dataset based on 8,000 retail clients of a large brokerage house over four years to evaluate if individual investors take decisions according to one of the dominating decision-making theories – traditional Expected Utility Theory or behavioural Prospect Theory. Another key question of my research is the role of affect in judgements and its impact on investment results and behaviour. The thesis includes three related empirical chapters. In the first empirical chapter, I explore how (ir)rational are retail investors and what are the boundaries of their rationality proxied with the relation between realised risk and return. In the second empirical chapter, I examine how the correlation between risk and return for the same group of investors varies in Live trading environment versus virtual Contest environment highlighting the role of emotions in correlation dynamics. In the third empirical chapter, I keep the emphasis on comparing Live and Contest investment settings, but now I evaluate the impact of emotions on profitability and various manifestations of risk behaviour. My research contributes to the academic literature in the domain of finance and investments that is trying to establish the positioning and the role of emotional account in the judgement and decision-making of economic agents. I provide empirical evidence that feelings have a substantial impact on investment results and risk behaviour of individual traders. The empirical nature of my analysis involving a large group of private investors grants significant support to prior findings that predominantly developed using neuro-physiological, interview-type and experimental methodologies. Besides, I present empirical support for the long-lasting debate concerning traditional and behavioural financial theories. Analysing the relation between risk and return, I manage to validate that investors in my sample manifest all behavioural patterns implied by Prospect Theory: they are risk-averse in the gains domain, risk-seeking in the losses domain and exposed to the loss aversion bias.

description: A construction of the bi-Hamiltonian structures for integrable systems on regular time scales is presented. The trace functional on an algebra of $δ$-pseudo-differential operators, valid on an arbitrary regular time scale, is introduced. The linear Poisson tensors and the related Hamiltonians are derived. The quadratic Poisson tensors is given by the use of the recursion operators of the Lax hierarchies. The theory is illustrated by $Δ$-differential counterparts of Ablowitz-Kaup-Newell-Segur and Kaup-Broer hierarchies.

description: Medicinal plants play an important role for the development of new drugs and potent therapeutic agents. Tridax procumbens, a widespread weed, is used as an important medicinal plant in Ayurveda. In the current scenario, several pathogenic organisms have become multidrug resistant due to indiscriminate use of antibiotics. There is a need to find out an alternative treatment strategy that will only inhibit the virulence of pathogens without challenging basic cell function so that they do not develop the resistance against antibiotics. Virulence of the pathogens is controlled by a phenomenon called Quorum sensing. The present study was therefore conducted to evaluate the anti-quorum sensing potential of the weed Tridax procumbens. Extracts of the plant were prepared in Soxhlet apparatus using solvents with increasing polarity. The extracts were tested for anti-swarming potential in Proteus mirabilis and pigment inhibition in Serratia marcescens. Petroleum ether and chloroform extracts were found to be the most potent inhibitors of quorum sensing in Proteus mirabilis showing 14% and 37.5% reduction in the diameter of the swarm zones and the number of the swarm rings also was significantly reduced. Dose dependent pigment inhibition in Serratia marcescens was observed in the presence of ethyl acetate and methanol extract with diameter of zones of pigment inhibition ranging from 14-31 mm. Results of the study indicate that the plant Tridax procumbens possess medicinal properties and can be studied further as a potent inhibitor of quorum sensing dependent virulence in pathogenic organisms.

description: An analysis of the stylized facts in financial time series is carried out. We find that, instead of the heavy tails in asset return distributions, the slow decay behaviour in autocorrelation functions of absolute returns is actually directly related to the degree of clustering of large fluctuations within the financial time series. We also introduce an index to quantitatively measure the clustering behaviour of fluctuations in these time series and show that big losses in financial markets usually lump more severely than big gains. We further give examples to demonstrate that comparing to conventional methods, our index enables one to extract more information from the financial time series.

description: With the use of tensor product of Hilbert space, and a diagonalization procedure from operator theory, we derive an approximation formula for a general class of stochastic integrals. Further we establish a generalized Fourier expansion for these stochastic integrals. In our extension, we circumvent some of the limitations of the more widely used stochastic integral due to Wiener and Ito, i.e., stochastic integration with respect to Brownian motion. Finally we discuss the connection between the two approaches, as well as a priori estimates and applications.

description: We characterize the physical properties of T Chamaeleontis, a transitional T Tauri star showing UX Ori-type variability, and of its associated disc, and probe possible effects of disc clearing processes. Different spectral diagnostics are examined, based on a rich collection of optical high- and low-resolution spectra. We determine radial and projected rotational velocities, and measure equivalent widths of the Li I (6708 A) line and of the most prominent emission lines (e.g. Ha, Hb and [OI] 6300A); we analyse shape changes of photospheric lines via bisector-method, while variability in Ha and Hb is inspected through line-profile correlation matrices. The strength of the Ha and Hb emission is highly variable and well correlated with that of the [OI] lines, as well as with Av variations of over three magnitudes. Variations up to nearly 10 km/s in the radial velocity of the star are measured on analogous time-scale, but with no apparent periodicity. SED modelling confirms the existence of a gap in the disc. Variable circumstellar extinction is pointed out as responsible for the conspicuous variations observed in the stellar continuum flux and for concomitant changes in the emission features by contrast effect. Clumpy structures, incorporating large dust grains and orbiting the star within a few tenths of AU, obscure episodically the star and, eventually, part of the inner circumstellar zone, while the bulk of the hydrogen lines emitting zone and outer low-density wind region traced by the [OI] remain unaffected. Coherently with this scenario, the detected radial velocity changes are also explainable in terms of clumpy materials transiting and partially obscuring the star.

description: We demonstrate that it is possible to confine electromagnetic radiation in cavities that are significantly smaller than the wavelength of the radiation it encapsulates. To this aim, we use the techniques of transformation optics. First, we present a "perfect cavity" of arbitrarily small size in which such confined modes can exist. Furthermore, we show that these eigenmodes have a continuous spectrum and that bending losses are absent, in contrast to what is observed in traditional microcavities. Finally, we introduce an alternative cavity configuration that is less sensitive to material imperfections and still exhibits deep subwavelength modes combined with high quality factor, even if considerable material losses are included. Such a cavity may be interesting for the storage of information in optical data processing and for applications in quantum optics.

description: Antimicrobial resistance bacteria (ARB) and antimicrobial resistance genes (ARG) have been regarded as emerging environmental pollutants in the entire world as these are known to cause public health hazards. The untreated biomedical wastes from healthcare units as well as the water from domestic and municipal wastes, are the sink for these pollutants and are disseminated into the river. The contaminated river's surface water with these pollutants poses a risk to public health due to the possibility of human exposure via bathing, drinking, and mobility in the food chain. In addition, heavy metals, the other major anthropogenic pollutant of river water, are known to drive bacterial resistance to antibiotics. Water of any urban city has been accepted as the index of determination of antimicrobial resistance (AMR) pollution load of any Urban city. No critical ethical issues are involved in conducting routine molecular surveillance and are considered safe to deal with. Therefore, understanding AMR pollution's state of the art is the utmost requisite before planning and designing their mitigation through biotransformation. Carbapenem resistance Acinetobacter baumannii (CARB pollutant) is designated as the world health organization (WHO) top priority pathogens, and it threatens serious infections in tertiary care hospitals. These CARB pollutants have the ability to persists in diverse environments, including water bodies. Our preliminary surveillance study reveals the danger of environmental contamination of drug-resistant and virulent CRAB strains in the Kathajodi river. Our results provide information on assessing risks to public health posed by the contamination of CRAB pathogens and toxic metals.

description: A luminous optical transient (OT) that appeared in NGC 300 in early 2008 had a maximum brightness, M_V ~ -12 to -13, intermediate between classical novae and supernovae. We present ground-based photometric and spectroscopic monitoring and adaptive-optics imaging of the OT, as well as pre- and post-outburst space-based imaging with HST and Spitzer. The optical spectrum at maximum showed an F-type supergiant photosphere with superposed emission lines of hydrogen, Ca II, and [Ca II], similar to the spectra of low-luminosity Type IIn "supernova impostors" like SN 2008S, as well as cool hypergiants like IRC +10420. The emission lines have a complex, double structure, indicating a bipolar outflow with velocities of ~75 km/s. The luminous energy released in the eruption was ~10^47 ergs, most of it emitted in the first 2 months. By registering new HST images with deep archival frames, we have precisely located the OT site, and find no detectable optical progenitor brighter than broad-band V magnitude 28.5. However, archival Spitzer images reveal a bright, non-variable mid-IR pre-outburst source. We conclude that the NGC 300 OT was a heavily dust-enshrouded luminous star, of ~10-15 Msun, which experienced an eruption that cleared the surrounding dust and initiated a bipolar wind. The progenitor was likely an OH/IR source which had begun to evolve on a blue loop toward higher temperatures, but the precise cause of the outburst remains uncertain.

description: Tuberculosis, caused by Mycobacterium tuberculosis, (Mtb) is one of the oldest diseases associated with mankind. Mtb, an intracellular pathogen, fine tunes its gene expression levels at transcriptional as well as translational level to survive the host immune responses. tRNA modifications provide an avenue to regulate protein synthesis in bacteria by selective up or down regulation of mRNAs with biased cognate codons. Several studies have shown regulation of tRNA modifications under various environmental stresses. N6-isopentenyladenosine modification at the 37th position of several tRNAs by isopentenyl transferase (MiaA) is a modification present in bacteria to mammals, which stabilizes codon-anticodon interactions during translation. In addition to increased translation fidelity and speed, i6A modification is essential for the adaptation to stationary phase and virulence in many bacteria. In order to identify tRNA targets of MiaA in Mtb, we analysed the tRNA sequences of Mtb for the A36-A37-A38 motif and identified 8 possible target tRNAs. Modification of the target tRNAs are confirmed by i6A assay providing the substrate dimethylallyl pyrophosphate and recombinant MiaA.

Despite its apparent unreasonableness, such a principle would realistically act in any organization where the mechanism of promotion rewards the best members and where the mechanism at their new level in the hierarchical structure does not depend on the competence they had at the previous level, usually because the tasks of the levels are very different to each other. Here we show, by means of agent based simulations, that if the latter two features actually hold in a given model of an organization with a hierarchical structure, then not only is the Peter principle unavoidable, but also it yields in turn a significant reduction of the global efficiency of the organization. Within a game theory-like approach, we explore different promotion strategies and we find, counterintuitively, that in order to avoid such an effect the best ways for improving the efficiency of a given organization are either to promote each time an agent at random or to promote randomly the best and the worst members in terms of competence.

description: Motivated by the gluon-chain model of flux tube formation, we compute and diagonalize the transfer matrix in lattice SU(2) gauge theory for states containing heavy static quark-antiquark sources, with separations up to one fermi. The elements of the transfer matrix are calculated by variational Monte Carlo methods, in a basis of states obtained by acting on the vacuum state with zero, one, and two-gluon operators in Coulomb gauge. The color Coulomb potential is obtained from the zero gluon to zero gluon element of the transfer matrix, and it is well-known that while this potential is asymptotically linear, it has a slope which is two to three times larger than the standard asymptotic string tension. We show that the addition of one and two gluon states results in a potential which is still linear, but the disagreement with the standard asymptotic string tension is reduced to 38% at the largest lattice coupling we have studied.

description: Organophosphates (OPs) are esters of phosphoric acid and phosphorothioic acid. They are powerful inhibitors of acetylcholinesterase (found in nervous tissues and erythrocytes) which results in accumulation of substrate acetylcholine leading to several health issues. Among several organophosphates, acephate is one of the most widely used and toxic pesticide. Acephate (C4H10NO3PS) is an organophosphate insecticide which is registered under The Insecticide Act, 1968 to be used on rice, safflower and cotton. But it is highly misused due to lack of proper knowledge regarding its use. Also, being water soluble it can be retained in environment for longer period of time. According to Environmental Protection Agency (EPA), acephate continuously stimulates the central nervous system resulting in dizziness, nausea, confusion, respiratory paralysis at very high exposures (e.g., accidents or major spills) and death in severe cases. Basically, three methods are utilized for the degradation of xenobiotic compounds, i.e., physical, chemical and biological degradation. The physicochemical approaches are generally expensive, often leading to the formation of the end products which are more persistent and equally or more toxic as compared to parent compound. Thus, bioremediation is preferred. Biodegradation of inorganic and organic pollutants occurs through stimulation of indigenous microbial population which help in conversion of the harmful compounds in less toxic products. The present study focusses upon the acephate degradation by microbes isolated from soil. Nine microbial cultures were isolated on the basis of their growth on acephate. Degradation was studied using plate assay followed by broth assay. Percentage degradation was recorded by UV-Visible spectrophotometer.

description: We study time-periodic forcing of spatially-extended patterns near a Turing-Hopf bifurcation point. A symmetry-based normal form analysis yields several predictions, including that (i) weak forcing near the intrinsic Hopf frequency enhances or suppresses the Turing amplitude by an amount that scales quadratically with the forcing strength, and (ii) the strongest effect is seen for forcing that is detuned from the Hopf frequency. To apply our results to specific models, we perform a perturbation analysis on general two-component reaction-diffusion systems, which reveals whether the forcing suppresses or enhances the spatial pattern. For the suppressing case, our results explain features of previous experiments on the CDIMA chemical reaction. However, we also find examples of the enhancing case, which has not yet been observed in experiment. Numerical simulations verify the predicted dependence on the forcing parameters.

description: Puntius sophore is one of the major food fish found in ponds of Mungeli District (Chhattisgarh). The infected Puntius sophore showed signs of saprolegniasis. In which the samples were taken between the month of July to November 2020. The length and weight of each sample were measured. The samples were taken separately in a polythene bag containing ice from a pond called Pathartal. These samples were kept in the Microbiology lab of CVRU Research center located at Dr.C.V. Raman University, Kargi Road Kota (Bilaspur) for in depth study and testing. Factors affecting infected Puntius sophore Saprolegnia parasitica studied. A culture medium called SDA( Sabouraud Dextrose Agar) was created to observe and identify the Saprolegnia parasitica fungus of infected Puntius sophore. Microscopic study was done to see the distinctive features of the fungus, for which methylene blue was used for staining. Photography of slide was taken by Dr. Rakesh Menghani (MD., Pathologist), Advanced Diagnostic Center, Tilak Nagar, Bilaspur (Chhattisgarh). Biochemical test of fungus presented in CVRU Research Center, Microbiology lab was done. MR (Methyl Red), VP (Voges Proskauer) and Indole (Kava's Indole) testing was done in biochemical test. As a result MR (Methyl Red) and Indole (Kava's Indole) test got positive (+ve) response while VP (Voges Proskauer) test got negative (-ve) response. Saprolegnia parasitica fungus confirmed. An experiment was carried out for control in which fresh Puntius sophore fish was taken, in which the above culture medium SDA (Sabouraud Dextrose Agar) was taken. During this time no colony of fungus was seen. Poor water quality, unsuitable temperature make it very easy to cause disease. Which causes an increase in the incidence of Saprolegniasis. Most of the outbreak of this disease is seen in the pond during the rainy season. This disease spreads very fast due to the arrival of contaminated water from outside in the pond.

description: We present an approach to calculate the atomic bulk solubility in binary alloys based on the statistical-thermodynamic theory of dilute lattice gas. The model considers all the appropriate ground states of the alloy and results in a simple Arrhenius-type temperature dependence determined by a {\it "low-solubility formation enthalpy"}. This quantity, directly obtainable from first-principle calculations, is defined as the composition derivative of the compound formation enthalpy with respect to nearby ground states. We apply the framework and calculate the solubility of the A specie in A-Ti alloys (A=Ag,Au,Cd,Co,Cr,Ir,W,Zn). In addition to determining unknown low-temperature ground states for the eight alloys, we find qualitative agreements with solubility experimental results. The presented formalism, correct in the low-solubility limit, should be considered as an appropriate starting point for determining if more computationally expensive formalisms are otherwise needed.

description: The study of left-invariant Einstein metrics on compact Lie groups which are naturally reductive was initiated by J. E. D'Atri and W. Ziller in 1979. In 1996 the second author obtained non-naturally reductive Einstein metrics on the Lie group SU(n) for $n \ge 6$, by using a method of Riemannian submersions. In the present work we prove existence of non-naturally reductive Einstein metrics on the compact simple Lie groups SO(n) ($n \geq 11$), $Sp(n)$ ($n \geq 3$), $E_6$, $E_7$, and $E_8$.

description: Biosynthesis of nanoparticles using the extract of medicinal plant in a non – hazardous mode has gained wide attention for various application in Nano medicine. The biological method of metal nanoparticles synthesis is more effective because of slow reduction rate of polydispersity of the final products. In our, study we have synthesized silver nanoparticles using leaves extract of Withania somnifera. The exposure of reaction mixture containing silver nitrate and dried leaves powder of Withania somnifera resulted in reduction of metal ions. Green synthesized silver nanoparticles were characterization by ultraviolet - visible spectroscopy and dynamic light scattering (DLS). Based on the above characterization data it is concluded that green silver nanoparticles have been synthesized.

description: One of the characteristics of individuals with attention deficit hyperactivity disorder (ADHD) is executive function deficits. According to a meta-analysis (Zhu et al.,2023), the best activities for improving the working memory of individuals with ADHD are closed skills dominated by aerobic exercises. Brailletonik is a new Iranian motor cognitive sport. In this sport, letters and words can be converted into movements using Braille codes. This skill is closed and serial and often performed aerobically. Thus, the purpose of the present study was to investigate the effect of Brailletonik training on the working memory in children with ADHD. Participants in the present study were 18 children with ADHD and 15 typically developing children (TD) aged 8-11 years old. The ADHD children were randomly assigned in 2 groups of Brailletonik and control. The working memory in pre-test and post-test were measured using the n-back task (owen et al., 2005). Experimental group participated in 11 sessions of Brailletonik training. The control group was asked to maintain their habitual daily activities during this period. Data were analyzed using independent-samples t test and ANOVA at p<0.05. According to the results, there were no significant differences between the hits, commission errors, and reaction times of children with and without ADHD (p > .05), but the omission errors of children with ADHD (M=7.6) were significantly more than TD children (p =0.024). After Brailletonik training, the significant difference between the omission errors of children with (M=2.5) and without ADHD (M=2.4) disappeared (p=0.93). It seems that the Brailletonik due to its aerobic and cognitive nature and the need to memorize and remember the letters codes in the desired words can improve the spatial working memory in ADHD children.
