Published: September 2023

Les patients en oncologie ont été particulièrement affectés par la pandémie de COVID-19. En effet, ce groupe a dû composer avec un risque plus élevé de complications liées à la COVID-19, en plus de voir certains de leurs rendez-vous médicaux et traitements annulés ou reportés. Ces changements dans la trajectoire de soins ont pu avoir un impact sur les niveaux de peur de la récidive du cancer (PRC). La présente étude, menée chez des femmes ayant reçu un diagnostic de cancer du sein, a pour objectif principal d’évaluer le niveau moyen de PRC et d’estimer la proportion de patientes ayant un niveau clinique de PRC au cours de la deuxième vague de COVID-19. À des fins comparatives, l’étude vise également à examiner le niveau moyen d’anxiété et de dépression, puis d’estimer la proportion de femmes présentant un niveau clinique de ces deux problèmes. Un total de 245 femmes ayant reçu un diagnostic de cancer au cours des cinq dernières années ont complété une batterie de questionnaires en ligne entre novembre 2020 et mars 2021. Les analyses descriptives révèlent que la proportion de patientes ayant un niveau clinique de PRC s’élève à 76,4% tandis que les proportions de patientes rapportant un niveau clinique d’anxiété et de dépression sont de 45,6% et 52,7%, respectivement. Ces résultats indiquent que la PRC est une problématique majeure en période pandémique.

Authors: Sarkar Payel , Dutta Espita , Sen Payel , Banerjee Rohan
Published: September 2023

The poultry processing industry produces approx 8.5 billion tons of feathers as by product peryear worldwide. According to Asian Network for Scientific Information India’s contributioalone is 350 million tons in 2010. This has become a part of solid waste management since it is tough to degrade feathers due to highly rigid structure rendered by extensive disulfide bonds andcross-linkages. In this present study, out of the isolated fifteen different keratinase producing bacterial stains, three isolates (belonged to the genera Xanthomonas) were selected to determine degradation of feathers. Complete degradation of 20g/L feather was achieved in just 5 days without any foul smell. Keratinase activity of 536.66 U/ml was noted after 48 hours incubation. Keratinase produced by Xanthomonas was isolated and purified using carboxymethyl cellulose ion–exchange and Sephadex G-75 gel chromatographies. The specific activity of the purified keratinase relative to that in original medium was approximately 86.9 fold. SDS-PAGE analysis and Sephadex G-75 chromatography indicated that the purified keratinase is monomeric and has a molecular mass of 31kDa. Under standard assay condition, the temperature and pH optimum of keratinase was 45°C and 9. Thus, this novel Xanthomonas strain can act as a potential tool to solve the feather waste pollution in short time span. The purified alkaline keratinase hasmultitude of applications in various industries.

Authors: Vignesh H. , Hema Kalai Rani R.
Published: September 2023

The banana (Musa spp.) is considered as an important crop plant due to its high economic value as good dietary source. Banana is the rich source of carbohydrates and vitamins, particularly vitamins B; it is also a good source of potassium, phosphorus, calcium and magnesium. Here, we analyzed the genetic relationship of four different banana varieties that are cultivated in south India. Random amplified polymorphic DNAs (RAPDs) fingerprinting of these banana varieties (Grand Naine, Nendran, Poovan and Red Banana) were carried out by five decamer primers (OP-5, OP-6, OP-7, OP-8,OP-11) led to DNA amplification. The distances in the dendrogram constructed by UPGMA (Unweighted pair group method Arithmetical Means) were compared with the genetic distances between genotypes pairs to calculate the cophenetic correlation. The genetic variation between Grand naine and Nendran was found to be 0.89 nucleotide. Similarly the Poovan is getting 0.94 nucleotide variation from the above one and Red is getting 0.97 nucleotide at the highest from all. The results presented here also contribute to narrowing the gaps in our current understanding of the migration path of bananas and the emergence of secondary centers of diversity. Cultivated bananas (Musa spp.) are mostly diploid or triploid cultivars with various combinations of the A and B genomes inherited from their diploid ancestors Musa acuminata Colla. and Musa balbisiana Colla. respectively.

Published: September 2023

In the present study, the relationship between photosynthetic activity (organic carbon accumulation) and salt excretion was observed in six salt excretory mangrove species of Sundarban. The study encompassed three different sites and stretched over a period of three prominent (premonsoon, monsoon and postmonsoon) seasons in order to evaluate the spatio-temporal variations. In general, a positive correlation was observed among rate of excretion of salt ions from the leaves to that of the rate of accumulation of organic carbon in the leaves of the species studied. The only deviations occurred during monsoon especially in the sodium and potassium ion excretion along with the photosynthetic activity, which supported the dependence of salt ion excretion on processes like photosynthesis strongly.

Uncertainty Analysis of Evapotranspiration Estimates in Ecosystems
Authors: Hofreiter Milan , Jirka Vladimír
Published: September 2023

Many hydrologic models and agricultural management applications require evapotranspiration estimates. The intensity of evapotranspiration is mainly determined by mathematical models rather than by direct measurement. In addition to its own estimate of evapotranspiration it is necessary to determine the uncertainty of this estimate. This uncertainty is not usually mentioned. In this paper these formulas are derived for the uncertainty estimate of evapotranspiration under simplifying assumptions. These assumptions enabled one to derive an expression of evapotranspiration estimation uncertainty suitable for practical applications. The paper focuses on both the absolute and the relative uncertainty of evapotranspiration estimation. The derived formulas can be used for determining the uncertainty in evapotranspiration estimation, but as well as for the accuracy estimate which is necessary for the measuring of input variables. The derived relationship shows that the net radiation should be more accurately measured than the other energy fluxes that have an influence on evapotranspiration. It follows that the relative uncertainty of evapotranspiration is primarily influenced by the relative uncertainty of net radiation. The uncertainty in the measurement of net radiation was derived from data obtained by using a radiometer which was equipped with a pair of pyranometers and with a pair of pyrgeometers. Planck’s Law was used for spectral analysis. The possible presence of systematic errors in the measuring of net radiation was evaluated for its potential impact on the errors of the evapotranspiration estimate. This paper is accompanied by measurement records and graphs documenting the achieved results.

Authors: Rashidifar Mohammad Amin , Amin Rashidifar Ali
Published: September 2023

Understanding of the flow in stirred vessels can be useful for a wide number of industrial applications, like in mining, chemical and pharmaceutical processes. Remodeling and redesigning these processes may have a significant impact on the overall design characteristics, affecting directly product quality and maintenance costs. In most cases the flow around the rotating impeller blades interacting with stationary baffles can cause rapid changes of the flow characteristics, which lead to high levels of turbulence and higher shear rates. The flow is anisotropic and inhomogeneous over the entire volume. A better understanding and a detailed documentation of the turbulent flow field is needed in order to design stirred tanks that can meet the required operation conditions. This paper describes an effort for accurate estimation of the velocity distribution and the turbulent characteristics (vorticity, turbulent kinetic energy, dissipation rate) in a cylindrical vessel agitated by a Rushton turbine (a disk with six flat blades). Results from simulations using FLUENT (a commercial CFD package) are compared with Time Resolved Digital Particle Image Velocimetry (DPIV) for baseline configurations in order to validate and verify the fidelity of the computations. Different turbulent models are used in this study in order to determine which one is the most appropriate. Subsequently a parametric analysis of the flow characteristics as a function of the clearance height of the impeller from the vessel floor is performed. Results are presented along planes normal or parallel to the impeller axis, displaying velocity vector fields and contour plots of vorticity turbulent dissipation and others. Special attention is focused in the neighborhood of the impeller region and the radial jet generated there. The present results provide useful information for the design of the mixing process as well as for more accurate estimations in future work.

Authors: Krishna Kumar M. , Santhana Muthu M. , Kanagaraj M.
Published: September 2023

In previous days, the lifetime of the battery in satellite is less. The challenge is to increase lifetime of the satellite by using the electronic circuit. This paper proposes a new design that can be used as a tool for increasing the lifetime of the batteries used in the satellite. Normally the satellite gets the energy from sun aswell as battery for its day to day activities. During the night time the satellite could not get the energy from the sun and so it gets the energy from battery only. During the time (6-10 AM & 2-6 PM), the satellite gets the energy from both sun and battery. And during the time (10 AM to 2 PM) the satellite fully gets the energy from sun but at the same time the battery will be charged from solar power. In this project the life time of the power consumption is decreased by means of a booster circuit. The project presents the control strategy and power management for an integrated 3 port converter which interface one solar input port, one bidirectional battery and an isolated output port.

Authors: Karthikeyan M. , Muthupandi R. , Satheeshkumar K. K. , Elango K. P.
Published: September 2023

This paper explains the possible use fo Polyaniline polypyrrole composite (PANi/PPy) as an adsorbent for the removal of the fluoride ions, from aqueous solution. The adsorption of the fluoride was appreciable around the natural pH of the aqueous solution of fluoride ions. This shows that adsorption of the fluoride ions could be carried out on the PANi/PPy composite without adjusting the pH of the medium. The experimental data yielded perfect fits with Freundlich isotherm equation. The values of the adsorption coefficients computed from the isotherms indicated the potential of the adsorbent for practical applications in defluoridation processes. Adsorption kinetics obeyed a first-order kinetic model. Diffusion of the fluoride ions into the micro pores and macro pores is the rate-determining step in the mechanism of the adsorption process. The adsorption of fluoride ions on the PANi/PPy composite was non-spontaneous and endothermic in nature with the defluoridation capacity increasing with increasing temperature due to increase in the rate of adsorption.The enthalpy change for the adsorption process was in the range of 25-67 kJ mol-1, which did not, indicates very strong chemical forces between the adsorbed fluoride ion and the PANi/PPy composite surface. This observation was well supported by the XRD pattern studies. Hence, physisorption seems to be the major mode of adsorption.

In an effort to provide a more efficient representation of the speech signal, the application of the wavelet analysis is considered. This research presents an effective and robust method for extracting features for speech processing. Here, we proposed a new human voice recognition system using the combination of decimated wavelet (DW) and Relative Spectra Algorithm with Linear Predictive coding. First, we will apply the proposed techniques to the training speech signals and then form a train feature vector which contains the low level features extracted, wavelet and linear predictive coefficients. Afterwards, the same process will be applied to the testing speech signals and will form a test feature vector. Now, we will compare the two feature vectors by calculating the Euclidean distance between the vectors to identify the speech and speaker. If the distance between two vectors is near to zero then the tested speech/speaker will be matched with the trained speech/speaker. Simulation results have been compared with LPC scheme, and shown that the proposed scheme has performed superior to the existing technique by using the fifty preloaded voice signals from six individuals, the verification tests have been carried and an accuracy rate of approximately 90 % has been achieved.

The aim of the study was to determine and classify the hand index of 200 individuals selected randomly within age group 18 – 65 years from Udaipur district, Rajasthan, India. The measured parameters are hand length and hand breadth. This study also attempt to compare the hand index obtained from direct as well as indirect (from hand print & hand outline) methods. Data were analyzed using SPSS Statistical software. Results shows that there were statistically significant differences in the hand parameters of male compared to female subjects for all observed parameters. It is interesting that hand index obtained from different methods doesn’t indicate variation however there exist statistically significant variation in terms of hand length and hand breadth. Also there is statistically significant difference between the hand dimensions obtained from different methods. Hand classification denoted that population of Rajasthan state belongs to dolichocheir (dch) group of hand for all the direct and indirect methods. The comparison of hand index with populations of 17 different states of India indicates that Indian population belongs to any category of hand index except hyperbrachycheir. Also an attempt has been made to observe the correlative effect of climate divisions of India with the hand categories. Comparison with 25 other foreign countries shows the existence of hyperbrachycheir that is broader large palm but short fingers. This shows that morphological characteristics of hand depend on many factors such as gender, ethnicity, socio-cultural domain, environment & genetic factors and it differs from region to region. Thus, it can be said that Identification of hand parameters is very helpful in concealing identity of mutilated remains in any disastrous act, also in examination of chance evidences in crime scene for criminal proceedings and this comparative data of hand index can also help to determine the resident place of an unknown individual.

Software measurements and blame information having a place with a past programming form are utilized to construct the product blame expectation show for the following arrival of the product. Unsupervised procedures like bunching might be utilized for blame expectation as a part of programming modules, all the more so in those situations where blame marks are not accessible. In this paper a Quad Tree-based Fuzzy C-Means calculation has been connected for anticipating deficiencies in program modules. The points of this paper are twofold. In the first place, Quad Trees are connected for observing the underlying group focuses to be contribution to the Fuzzy C-Means Algorithm. An information edge parameter oversees the quantity of introductory bunch focuses and by shifting the limit the client can create wanted beginning group focuses. The idea of grouping increase has been utilized to decide the nature of bunches for assessment of the Quad Tree-based introduction calculation when contrasted with other instatement procedures. These bunches got by Quad Tree-based calculation were found to have most extreme pick up qualities. Second, the Quad Tree based calculation is connected for anticipating shortcomings in program modules. The general blunder rates of this forecast approach are contrasted with other existing calculations and are observed to be better in the vast majority of the cases.

Object apprehension and article acceptance are capital apparatus of every computer eyes system. Despite the top computational complication and added problems accompanying to after adherence and accuracy, Zernike moments of 2D images (ZMs) accept apparent animation if acclimated in article acceptance and accept been acclimated in various angel assay applications. In this work, we adduce a atypical adjustment for accretion ZMs via Fast Fourier Transform (FFT). Notably, this is the aboriginal algorithm that can accomplish ZMs up to acutely high orders accurately, e.g., it can be acclimated to accomplish ZMs for orders up to 1000 or even higher. Furthermore, the proposed adjustment is as well simpler and faster than the added methods due to the availability of FFT software and hardware. The accuracies and after adherence of ZMs computed via FFT accept been confirmed using the orthogonality property. We as well acquaint normalizing ZMs with Neumann agency if the image is anchored in a beyond grid, and blush angel about-face based on RGB normalization of the reconstructed images. Astonishingly, higher-order angel about-face abstracts appearance that the proposed methods are superior, both quantitatively and subjectively, compared to the q-recursive method.

Now a day, there is a growth of digital images and video archives. Some of these are very important from user point of view. The collection of these digital images may be for personal use and may be for public use. For searching images in the database, there is the need of secure, fast and efficient techniques. Tag-based image search is an effective technique to find images in the databases and in the social websites. In this paper a reranking system for image retrieval with the consideration of images relevance and diversity is proposed. Reranking of the images have done according to their visual features and semantic features. Visual features are used for detecting duplicate images in proposed method. Each user maintains several images. First sort these images by same group user ranking system. Users that have higher contribution to the given query rank higher. Then an implementation to all-user reranking on the ranked users image set and only the most relevant image from users image set is selected. These selected images compose the final retrieval results. We build an inverted structure for the image dataset to speed up the searching process.

The radiation effects on unsteady transient free convection flow of a viscous incompressible gray, absorbing-emitting but non-scattering, optically-thick fluid occupying a semi-infinite porous regime adjacent to an infinite moving hot vertical plate with constant velocity taking viscous dissipation onto account has been carried out. Thermal radiation effects are simulated via a radiation-conduction parameter (),rK based on the Rossseland diffusion approximation. We employ a Darcian viscous flow model for the porous medium. The momentum and thermal boundary layer equations are non-dimensionalzed using appropriate transformations and then solved subject to physically realistic boundary conditions using the Ritz finite element method. The computed numerical results for velocity(),u temperature(),θ shear stress function()τ and wall temperature gradient function()Nu are presented through the graphs and tables for air (0.71)rP= and water (7.00).rP= It has been found that increasing thermal radiation parameter ()rKcauses a considerable increase in the flow velocity .u Temperature θ is significantly increased within the boundary layer with a rise in.rK The velocity is found to decrease with an increase in inverse permeability parameter ()pK and increases with increase in the Grashof number ()rG and Eckert number ().
