Expanded Bed Adsorption: An Option For Energy Savings In Multiple Proteins Purification
Authors: C Kavitha T , Krishna B.S.V.S.R.
Published: January 2021

Expanded Bed Adsorption enables the protein recovery directly from cultivations of microorganisms or cells and preparations of disrupted cells, without the need for prior removal of suspended solids. The performance ofan expanded bed is comparable to a packed bed owing to reduced mixing of the adsorbent particles, clogging/plugging of solid particles in the column, while fluidized bed requires more velocity which may hinder the adsorption equilibrium. However,optimal operating conditions are more restricted than in a packed bed/fluidized bed due to the dependence of bed expansion on the sizeand density of the adsorbent particles as well as the viscosity and density of the feedstock. These difficulties can beovercomes in expanded-bed chromatography. In this work the steady state hydrodynamic behaviour of expanded beds studied experimentally.The present study focused on hydrodynamics of multiple particles separation and subsequently can be applied to the multiple proteins separation in a single expanded bed.

Authors: Bhoite Tushar D. , Pawar Prashant M. , Gaikwad Bhaskar D.
Published: January 2021

Chain Link assembly is extensively used in the industry, the scope of this paper is to review the applications in the industry and explore the design considerations that go into the design of the assembly. The paper delves into various application aspects and manufacturing aspects to formulate an idea of the system. Finally Finite Element Analysis (FEA) has been used to conduct shape optimization. Since lot of work has already been
done in other components, in this paper the focus has been narrowed down to specific component of outer link. Within the outer link, most dimensions in the industry are parametrically defined, however one dimension, the radius that is in between the inter connecting holes is left to manufacturer convenience. In this paper we assess the impact of this radius on the stress in the system, and see if material saving and consequently efficiency increment is possible.
OPTIMALLY LOCATED SVC FOR TRANSMISSION OF RENEWABLE ENERGY IN LARGE POWER SYSTEM
Authors: DEVI M.LAXMI , AHAMMAD SK.SHAKEER , REDDY G.SRINIVASULU
Published: January 2021

Shunt FACTS devices provide the possibility to control voltages and therefore to improve the security of the system. In order to use this possibility, the optimal location and the set values of the FACTS controllers have to be selected correctly. The singular analysis of the power system Jacobian matrix are applied to identify the optimal location of shunt FACTS devices in large power systems. Furthermore the application of Optimal Power Flow control is a possible method for choosing set values. In this paper a sensitivity index for the detection of sensor nodes is defined. Sensitivity analysis is used
to determine the area on which the FACTS device has significant influence. And then only this limited area is included in the Optimal Power Flow control, because it is very difficult to include the entire system into the optimization process. Matlab code is written to find the optimal location of Shunt Facts device i.e., SVC. Furthermore the objective function of Optimal Power Flow control is analyzed. This function consists of three components. A certain type of FACTS is not able to influence all these components.
OPTIMIZATION OF THE PERFORMANCE OF THE WIND POWER GENERATION UNIT BY USING DIFFERENT NEURAL NETWORKS
Authors: JAIN PANKAJ , SETHI V.K. , PANDEY MUKESH , SHARMA P.B.
Published: January 2021

The wind power generation is a pollution free technique for electricity production, and also it does not requires additional driving source like coal hence after installing once the generation cost can be minimize but the power generation by this method requires a continuous wind flow in all weather. Unfortunately the wind velocity is weather dependent and changes widely with time to time. This create difficulties in the system scheduling, dispatching & power distribution hence it requires a predictive system which can estimate the wind velocity in advance & so will help in power management. In this paper we analyzed RBF (radial basis function), FFBP (feed forward back propagation) & CFBP (cascade forward back propagation) neural networks for this purpose. At last the simulation results and discussion are presented.

IMPACT OF STATIC VAR COMPENSATORS ON POWER SYSTEM: A CASE STUDY
Authors: KOUR GUNEET , BRAR G.S. , JASWANTI JASWANTI
Published: January 2021

With increase in load, any transmission, distribution and generating model suffers from disturbances. These disturbances effect the overall stability of the system. Criterias like voltage profile, power flows, losses tell us about the state of the system under study. Load flow analysis of the system under study is capable of providing the insight of the
system. The Emergence of FACTS device is really a step forward for the flexible control or Power System Operations. FACTS is the name given to the application of the power electronics devices to control power flows and other quantities in the power system. But when it comes to implementation stage, optimizing the location becomes a great concern because of the high cost involved with FACTS devices especially converter like SVC, STATCOM etc. Static Var Compensator (SVC) is a power quality device, which employs power electronics to control the reactive power flow of the system where it
is connected. It is able to provide fast-acting reactive power compensation on electrical systems. SVC is one of the methods and can be applied to obtain a system with least losses, increased power flow and healthy voltage profile. Number, location and size of SVC are the main concerns and they can be optimized to a great extent by Genetic Algorithm (GA) or any other method. Use of SVC in a system has shown considerable increase in voltage profile and power flows while decrease in losses.
Detection of MDPSK in Fading Channels using Gaussian Particle Filter
Authors: Sudhakar P. , Krishna P. Gopi , Rani Dr. D. Elizabeth
Published: January 2021

We propose Gaussian particle filtering approach for solving the problem of corrupting the
MDPSK signals by fading as well as noise. Particle filtering is a powerful tool for non linear
problems but it faces sampling degeneration problem which leads to re‐sampling process.
Gaussian Particle Filtering doesn’t need re‐sampling process because it approximates the
posterior distribution as Gaussian.GPF is preferable than PF for fading channels.

Authors: Tripathy Debasis , Barik Amar Kumar , Rao B. Srinivas , Rout Ranjita
Published: January 2021

This paper discusses the design of a virtual instrument for detection and analysis of power quality disturbances in Power System using Wavelet Packet Transform with the help of LabVIEW® algorithm. The virtual instrument designed can operate in different working modes depending on the type of power quality disturbances to be detected and analyzed. Different wavelet analysis (discrete or wavelet-packet transform), with different mother wavelet, decomposition tree and different sampling rate is performed on the input signal either in real-time or off-line. The instrument also permits the partial
implementation of a wavelet decomposition tree when we are only interested in a specific frequency band in the input signal. The real signals from chroma programming are used in LabVIEW® algorithm by Data Acquisition (DAQ) card to acquire and
digitize the input line signal to obtain the results. The results obtained in simulation using real signals demonstrate good performance of the instrument developed for the detection and analysis of different power quality disturbances with proper time information of the signal. This helps us to analyze the power quality problems to improve the supply quality of the power system effectively by taking proper preventive measures

Authors: Patnaik Prabhat K. , Kumar P. Santosh , Nayak Prabhakar
Published: January 2021

This paper presents an efficient approach based on neural network to design a square ring micro-strip antenna. Traditional techniques used to design a square ring antenna are based on EM field simulations like IE3D which is highly CPU intensive and requires lot of time for simulation. Neural networks can be used to map the complex relationship between physical and electrical parameters of ring antenna in an efficient manner. The model once developed can be used with minimal CPU resources and enables fast extraction of output parameter such as resonant frequency. The typical resonant frequency values are first obtained through IE3D and then from samples obtained from IE3D are used to train the neural network .The results obtained by the use of neural networks have been proved to be faster than comparison with IE3D software.

A Study on Economic Value Added and Share Price Behaviour: The Recent Analysis
Authors: ATTAH KUMAH EMMANUEL
Published: January 2021

Many companies seem to have destroyed shareholder's wealth over a period of time and only a few have positively contributed to their wealth. With the help of Economic Value Added (EVA) and Market Value Added (MVA) which tell what the institution is doing with investor's hard earned money, this research examines the relationship between the share price and other economic and financial variables such as Economic Value Added (EVA), Return on Asset (ROA) and Return on Fund (ROF). The overriding message of this paper is that the share price has direct correlation between the economic and financial variables. This analysis helps us to dig below the surface numbers to tell us more about the underlying business and whether there is a prima facie case for using EVA as one of the ranges of performance measurement tools. The relationship between EVA and other traditional measures is examined using Pearson's Coefficient of Correlation. Regression analysis has been used to examine the relationship of EVA, Earning Per Share (EPS), ROA and ROF with share price. The study found that, investing in the market is becoming more and more risky as the beta of the individual securities is increasing year by year. The increase in beta is due to increasing weighted average cost of capital; it specifies that capital is becoming more and more costly; Majority of the banks are increasing their capital to meet the increased expenses. As the market is becoming more and more risky, investors' expectations are increasing and therefore share prices of almost all the banks for almost all the years showed an increasing trend. Data analysis of 39 banks shows that: Share prices of two banks' shows high correlation of coefficient and coefficient of determination with EVA and share prices of eighteen banks' shows low correlation of coefficient and coefficient of determination with EVA. This specifies that there is no relationship between EVA and share price.

Published: January 2021

With the information influx from the hypermedia environment, queries have been made on the reading landscape, markedly related to college and adult readers, as they are perceived to have limited experience with the hypermedia environment. This environment calls on new literacies for a reader to cope with reading tasks inherent to its features. In this context, new challenges have been posed regarding online reading strategies of college and adult readers. With the dearth of literature about how college and adult readers navigate their way in their reading tasks in the hypermedia environment, this paper described their strategies in reading. The information gathered from the studies conducted before can contribute to the present plight of our readers who need to navigate their way through reading in a hypermedia environment. Eight studies that met the criteria on the variables of the study were included. The studies revealed the following reading strategies of college and adult readers: global, problem-solving, local, cognitive and metacognitive, and navigation strategies. This evidenced that print-based reading strategies are basics on which reading strategies in the hypermedia environment are built for strategic readers to be successful in their online reading tasks.

Published: January 2021

La identidad profesional del profesorado afecta a la forma de ser y actuar como profesor (1).  Por ello, es importante trabajarla específicamente en la formación inicial. La interacción, la reflexión y la acción han demostrado ser elementos formativos eficaces para trabajar la identidad profesional en la formación inicial del profesorado. En esta experiencia educativa se han utilizado diferentes estrategias que incluyen dichos elementos con el objetivo de analizar su impacto específico en el aprendizaje y en el desarrollo de la identidad docente.  Las estrategias didácticas utilizadas en esta práctica educativa son la metáfora, el diario de prácticas, el aprendizaje basado en la investigación y las tertulias pedagógicas dialógicas llevadas a cabo en una metodología de tutoría entre iguales. La muestra está compuesta por 68 estudiantes del Máster en Formación del Profesorado de Educación Secundaria. Los resultados indican que las estrategias metodológicas utilizadas en esta experiencia de tutoría entre iguales han favorecido el desarrollo de la identidad profesional en un clima de aprendizaje positivo. Se puede concluir que promover estrategias basadas en la interacción, la reflexión y la acción ayuda a profundizar sobre la identidad del profesorado. Además, permite un desarrollo de las competencias docentes y un mayor conocimiento de estrategias didácticas específicas que pueden ser transferibles a su desempeño docente.

 
Protecting Biodiversity via Metaphysical Angels of the Future
Authors: Louisson Amalia
Published: January 2021

Global trends in contemporary left biodiversity protection practices are self-undermining because they are fixated on resurrecting past ecological conditions, while failing to prepare for the future. Not only will many species be unable to survive in predicted future conditions, but focusing on the past has forfeited the future to capital. Instead, this paper presented at the ISSHS School for Politics and Critique 2020 takes the recently resurrected figure of Prometheus to promote an environmentalism that casts its eyes to the future. It will be argued that preparing the future for biodiversity can sever capital’s claim over the future by prompting a traumatic instance of physicality.

A NOTE ON THE PAPER “ON COMPLETENESS IN METRIC SPACES AND FIXED POINT THEOREMS"
Authors: Khantwal Deepak , Gairola Umesh Cuandra
Published: January 2021

In the present note, we show that the assumption of continuity used in the fixed point theorem of Gregori et al. (Results Math. 73 (2018), no. 4, Art. 142, 13) can be relaxed to some weaker version of continuity. More precisely, we prove a fixed point theorem for orbitally continuous and k-continuous mappings in weak G-complete metric space and provide an appropriate example to show that our result is not only valid for continuous mappings but also for some discontinuous mappings. Moreover, we apply our main result to establish a common fixed point theorem for two self-mappings
MORPHO-FUNCTIONAL AND DEVELOPMENTAL STUDY OF SWIM BLADDER IN
PRE TO POST FLEXION STAGES LARVAE OF HIMALAYAN SNOW TROUT SCHIZOTHORAX PLAGIOSTOMUS (HECKEL) REARED IN ARTIFICIAL AND NATURAL CONDITIONS
Authors: Rayal Rajesh
Published: January 2021

Present study deals with histology, gross morphology of the larvae and its behavioural aspects to describe the progression of the development of swim bladder in pre to post flexion stages larvae of the Himalayan Snow Trout Schizothorax plagiostomus (Heckel) reared in laboratory as well as in natural site. It reveals a very significant information in respect to derivation, tissue differentiation, initial inflation as well as factors responsible for noninflation of swim bladder especially among laboratory reared larvae. At hatching (108-110 and 124-130 hours after fertilization in laboratory and natural site respectively), larvae measured 9.00 mm and 10.5 mm in laboratory and natural site respectively, and their body cavity was mostly occupied with a huge amount of yolk. The mouth,
pharynx and esophagus were impervious till 3rd day post hatching (dph). Primordial swim bladder appeared on 3rd.dph as a cluster of mesenchymal cells evaginating from the posterior dorsal surface of the differentiating esophagus. Later on it grows toward the caudal direction below the differentiating vertebral column and kidney. Initial swim bladder inflation occurred by 6-dph when larvae attained 12.50–13.50 mm length, with the onset of first exogenous feeding. During this phase a mucous like substance was also observed in the pneumatic duct as well as lumen of swim bladder of some laboratory reared larvae and later on they got mortality. By 8-dph well differentiated and
inflated swim bladder becomes externally visible and pneumatic duct extended to join the dorsal wall of esophagus. A number of biotic and abiotic factors were found associated with preventing swim bladder inflation during Pre flexion to Post flexion stages.
INFESTATION OF NEMATODE PARASITE FILOCHONA TELEOSTEI IN RELATION TO SIZE, WEIGHT AND AGE OF SNOW TROUT SCHIZOTHORAX RICHARDSONII (GRAY)
Authors: Singh Omveer , Panwar Shweta
Published: January 2021

Parasitological investigation was conducted to assess the effects of various biotic factors viz. length, weight and age of host on the infection patterns of Filochona teleostei (Singh & Malik, 1992) in snow trout Schizothorax richardsonii (HAM.) from hill streams of Garhwal Himalayas. The statistical analysis was carried out to calculate infection incidence, mean worm burden, regression values and their significance. About 20% fishes (18% male and 22% female) were found infected with nematode parasites. Infection patterns of Filochona teleostei revealed a negative correlation (r= - 0.347 to - 0.734) with length, (r= - 0.499 to - 0.671) with weight and (r= - 0.576) with age of host fish. The age immunity and stronger host resistance developed by the larger fishes are the possible reasons for the decrease in infection in larger and older fishes.
ADAPTATION TO CLIMATE CHANGE BASED ON FARMERS’PERCEPTION: A STUDY ON INDIGENOUS HILLS CULTIVATORS IN NAGALAND, INDIA
Authors: Roy Niranjan , Debnath Avijit , Nautiyal Sunil
Published: January 2021

Climate change is believed to have severe impacts on different sectors of an economy especially the agricultural sector. The adverse impact of climate change, however, can be mitigated if farmers have awareness and better level of adaptive responses. This study examines the perception of farmers belong to indigenous communities in the state of Nagaland of Northeast India on climate change and analyzes their adaptation responses to climate change. A hundred and twenty farming households were interviewed during July and August 2019. The study employed the Heckman sample selection model to analyse the two- step process of adaptation to climate change. Farmers’ perception of climate change was significantly related to the age of the head of the household, level of education, and past experience of drought and flood. On the other hand, adaptation to climate change is determined by education of household head, economic status, and access to credit, type of cultivation, non-farm income, farming experience, distance to market, and past experience of climatic hazard
EVALUATION OF FEEDING INDICES TO ANALYSE THE FOOD PREFERENCE AND FEEDING RATE OF MACROBRACHIUM ASSAMENSE PENINSULARE (TIWARI, 1958) FROM RAWASAN STREAM OF GARHWAL, CENTRAL HIMALAYA, INDIA

Published: January 2021

In this paper the feeding index (FI), Gastro somatic index (GaSI) and Food Prevalence Index (FPI) of freshwater prawn Macrobrachium assamense peninsulare were evaluated to assess the quantity and quality of food preferred by it in the Rawasan stream. A total of 401 prawns were collected during a span of two years from five selected sites in the Rawasan stream of Garhwal in Central Himalaya, India from August 2013 to July 2015.
Collected prawns were in the size range of 20-75 mm in males and 24-65 mm in females in total length. The stomach contents of 10 collected specimens were examined monthly and observed that 35% of the stomach was full or semifull and 15% stomach were empty. The highest Gastro somatic value was obtained 2.95±0.80 during June in the male and 3.25±0.44 during May in the female. After that, it gradually decreased in both the sexes and is repeated in cyclic patterns each year. More or less a similar trend was reported in the feeding index value during the study which indicates a significant relationship between feeding intensity and Gastro somatic index. The highest Food Prevalence Index (FPI) was seen as fragments of animal matter in both sexes, which was (88.48) in male and (58.26) in female prawns and the lowest FPI value was sand and debris (7.9 and 5.7) in male and female prawn respectively. The main food items were the fragment of plants as well as animals, diatoms, algae, and sand. Overall, the results show that this prawn is selectively abstemious.
