DESIGN & DEVELOPMENT OF A LOW-COST DIAGNOSTIC TOOL TO DETECT GASTROPATHOLOGY CONSIDERING ELECTROGASTROGRAM

Wed, 29 Jan 2020 15:10:20 +0530

Electrogastrogram is the recording the abdominal myo-electrical activity. This technique is referred to as Electrogastrography. However, the electrical activities in the gastric region depend on various reasons so making it quite difficult to obtain the exact record. Theoretically, it is said that the contrast between the normal and pathological condition can be observed by a good margin. So even if it cannot produce an exact record for accurate diagnostic result, it can be used to detect whether a diagnosis is required or not. In this present work we have designed an indigenous kit for identification of the gastro pathological like ulceration, gastritis, acid reflux, detection of barrett, etc just to name a few considering the electrogastrogram so that is can serve as a cost-effective diagnostic tool for further medical intervention. The interest is mainly because of the non-invasiveness and simplicity of this method as compared to the other well established medical techniques. The painful endoscopic procedures involving patients endurance of pain has deeply motivated us with the need of a painless technique for the diagnostic treatment.

It's a fairly simple task for humans to determine the gender of an individual using certain facial features, although it is difficult for machines to perform an equivalent task. Within the past decade, unimaginable steps have been taken to automatically predict the gender from a face image. The human face has certain distinctive features such as eyes, nose, lips, etc., which can be analyzed to classify humans into two basic genders: Male and Female. This project aims at achieving a similar goal of detecting gender from face images. The basic tool used in the project is Convolutional Neural Network (CNN) along with the use of the Programming language Python. In recent years, face detection has achieved considerable attention from researchers in biometrics, pattern recognition, and computer vision groups. There are countless security and forensic applications requiring the use of face recognition technologies which have motivated us to explore this area and start with this project.

IoT based fuel level monitoring and fuel theft detection system

Wed, 19 Feb 2020 16:08:21 +0530

The project aims how the level of fuel can be monitored from a distant place and in case of theft can be detected easily from that place. For this, a level sensor will be needed which continuously will take the readings of the level of fuel at the tank (vehicle tank or any reservoir) and this level sensor will be connected to a microcontroller input.

The IoT implementation part is the level of the fuel can be continuously monitored by displaying it on a website using an ESP8266 NodeMCU.

Now to fulfil the second part i.e. to make it a fuel theft detection system there would be a threshold value of decreasing rate of the fuel level height. If the decreasing rate of fuel is greater than the threshold level an alarm will be sent to its owner in case of a vehicle tank or a buzzer will be on in case of industrial reservoir.

Subhadeep Basu — Tue, 25 Feb 2020 11:43:47 +0530

Speech signal is analog in nature. The maximum frequency component present in human voice signal can be taken approximately as 3-4KHz.In many modern day applications, it is often required to process the speech signal in digital domain. For this reason, digital processing of analog speech signal is highly important. Delta Modulation is a scheme that can be used to implement digital representation of analog speech signal. In this work, the speech signal is modulated and demodulated using a very simple technique, known as Delta Modulation(DM). Moreover, several other aspects like silence removal, Signal to Noise ratio (SNR) calculation and Power Spectral Density(PSD) analysis has also been carried out.

Use Of ECG/ EOG/ EEG for the Purpose of Health Monitoring of Partially or Fully Paralyzed Patient and to Communicate with the Patient in Case of an Emergency

Fri, 28 Feb 2020 18:42:04 +0530

It is never felt safe to leave a partially or fully disable person alone with a caretaker, it does not matter how much care is taken by the caretaker. In this paper, three different ways are described how the condition of a partially or fully disabled person can be monitored and in case of any problem, the partially or fully disabled person can communicate with his/ her family members. In the first way using Electrocardiography (ECG) the condition of the heart of the disabled person is continuously monitored and whenever something unwanted has happened a message is sent to his/her caring family member with the help of a microcontroller. This also can be done using Electrooculography (EOG). This can be applied to a partially paralyzed person. Here it is mentioned that the person is partially paralyzed because the EOG works on the movement of the cornea so the person should be capable of moving his/ her cornea. Now if the cornea of the person is bent over a set point a message is sent to a specific person. The same can be done with the help of EEG using brain signals. The brain signals are continuously monitored and in case of any unexpected or absurd signal message will be sent to the disabled person’s family member.

AN INNOVATIVE WATER SUPPLY SYSTEM

Sat, 07 Mar 2020 13:43:31 +0530

This paper reviews the challenges in water supply system, development and distribution of systems to manage water quality, leakages and contamination of drinking water in transmission network and managing pipeline network. Nowadays the wireless communication system is trending because of it’s impact in the field of healthcare, agriculture, safety measurements where as it plays the decisive role for developing the monitoring of systems. Water distribution systems made up of networks of pipes which can be in poor states of repair that are buried beneath our streets and relatively inaccessible. So to manage these systems the reliable data is needed to understand and detect water losses due to leaks or burst events, abnormality in the control of water quality. In this paper, we present a system to monitor the supply of water by the implementation of IoT. We detect the leakage using flow meter. The usage and wastage of water is tracked by the sensors and an alerter is used to notify the user if there is any contamination in drinking water. This proposed water supplying monitoring system will help the users to track and manage the supplying system, to evacuate the residue of chlorine left where as to distribute water equally in all the places.

Technical Education A Brief History And Continual Development Of Polytechnic Education In West Bengal.

Amitabha Ray — Thu, 24 Oct 2019 13:05:29 +0530

In 1757, the battle of Plassey gave the Britishers unique opportunity to change their status from commercial traders to colonizers. Thus Britain’s relations with India underwent a drastic qualitative change. Britain gradually captured the political power and became the rulers of this country. To rule any country the rulers should have an intimate knowledge of its topography and resources through physical survey.So in 1794, the English traders established a Survey School at Madras to train Indian personnel in modern land survey to assist British surveyor. The major initiative of starting a new centres of technical education came out of the necessity of the British rulers for training the diddle level technical required for construction and maintenance of public buildings, roads, canals, ports and harbours, railways and other services as well as training artisans and craftsmen in the maintenance of instruments and equipments needed for army, navy and other technical establishments. In 1825 Technical schools were established in Calcutta and Bombay for training the artisans and artificers. These schools were attested to ordinance factories and engineering establishments. Technical education was always on demand when there was crisis like war. natural calamities, change of political power etc. but not in a systematic manner like other education system. So there were some sort of development during the period of world wars. In this process AICTE formed in 1945.

SUNLIGHT FOR REMEDIATION OF POLLUTED ENVIRONMENT

Sampa Chakraborty — Thu, 24 Oct 2019 14:25:20 +0530

The day when the prehistoric man invented fire, the demand of energy started; at the same time environmental pollution also started from that day since combustion of fuel generates undesirable greenhouse gas. With the advent of civilization, both energy-crisis and anthropogenic pollution increased. Meanwhile the definition of civilization started changing during the industrial revolution. Life of people changed after industrial revolution and civilization demanded more and more energy every day. To generate such energy from conventional sources, we still have no other alternative than to pollute the environment. Other developmental activities also resulted in pollution of the environment. Consequently the conventional resources for energy generation are depleted and at the same time environment deteriorates. People started getting aware about the environment since 1980s. There are several remedial solutions for environmental problems using advanced technologies, but most of them, once again, need huge energy. For example, we have to boil water to get rid of the pathogens, we have to switch on UV lamps for detoxification of water. In an effluent-treatment plant there are pumps and other equipment that need energy. This is therefore a vicious cycle and to break the cycle, we must use renewable energy for environmental remediation.

Modelling and Analysis of a Solar Biomass Hybrid Vapour Absorption Refrigeration System for running a Cold Storage of Potato in India

Pradeepta Panja, A Ganguly — Thu, 24 Oct 2019 20:44:08 +0530

India suffers from the wastage of a large amount of agricultural produce due to the lack of proper post-harvest storage system. In this paper, an attempt has been made to propose a novel hybrid solar thermal and biomass driven refrigeration system. The refrigeration cycle used here employs a LiBr-H₂O vapour absorption refrigeration system used for storage of potatoes in cold storage. The objective of the hybrid power system proposed here is to produce a favourable micro-climate inside the cold storage throughout a calendar year irrespective of the seasonal variations in weather. The modelling equations of the proposed system have been developed and solved with the help of Engineering Equation Solver for the location of New Delhi (28^o35’ N, 77^o12’ E). The results of the proposed model are validated against a reference model study available in literature and a very good agreement is achieved with a root mean square error of 0.98% in the value of COP. A rudimentary cost analysis has also been included to assess the economic viability of the proposed system. The study thus reinforces the viability of using a solar biomass hybrid system for operation in the rural areas of a developing nation like India.

SETTING-UP OF CHAIN-LINKED FOOD PROCESSING UNITS THROUGH SELF HELP GROUPS USING ‘NBMS’ MODEL

Nilanjan Sengupta, Ratan Majumder — Tue, 03 Sep 2019 00:00:00 +0530

A staggering 25 to 30 per cent of production of fruits and vegetables in India is lost due to wastage. India ranks first few positions globally in the production of fruits and vegetables. But hardly one percent of the annual production of fruit and vegetables is processed in this country which is much lower compared to other developing nations.

Food Processing and other post-harvest technologies are the best option available to reduce the wastage of 50% of food and vegetable products and enhance food security of the country. The right post harvest practices such as good processing techniques, and proper packaging, transportation and storage can play a significant role in reducing spoilage and extending shelf life. Indians spend about 50% of household expenditure on food items. Demand for processed/convenience food is constantly on the rise. India's comparatively cheaper workforce can be effectively utilised to setup large low cost production bases for domestic and export markets. A chain-linked model of food processing at rural level can be developed using NBMS (Nodal-Big-Medium-Small) model and involving the Self Help Groups. The capital required for this business will be evenly distributed among the groups lessening the economic burden on them and the ongoing schemes and grants of different government departments can be clubbed together to assist the Self Help Groups to enter into this foray.

Use of Cost-effective Eco-friendly Construction Technologies (CECT) in housing sector in India has the potential to be the most appropriate in terms of economy and acceptability. The reduced cost of building, enhancement of comfort level and non-compromise on safety would decide choice of CECT, which will also act as a market force and demand for such technologies is expected to grow-up. This paper explored the acceptability and adaptability potential of different CECTs with special emphasis on Rat-trap Bond Wall and Filler Slab Roof, through literature study and technical calculations and tried to evaluate the appropriateness of those.

Bridging Academia and Industry

Nilanjan Sengupta — Wed, 04 Sep 2019 17:48:54 +0530

Very often people with degrees in engineering, who are employed in different industries don't go in for research and technology development, even though they may have a talent for it. Further, industry is not keen to invest in R&D unless its innovations are adequately protected and rewarded by way of assured Return of Investment. This has now become critical in the era of globalisation. In these changed circumstances, it will become even more essential to encourage R&D funding by industry. Hi-tech industries in advanced countries are allowed to generate investable surpluses through their own rational pricing structure and profit margins. This way they are able to meet a substantial part of their R&D investments through internal accruals.

Aishik Das, Arnesh Sen, Debasmith Das — Thu, 12 Sep 2019 19:07:57 +0530

Nowadays with the invent of new technologies the processors in the electronic devices have improved both in performance and speed. QUALCOMM has come up with its design like the MSM7225 which is a 1 core up to 800 MHz Cortex-A5(ARMv7): 32K+32K L1, 256K L2 and the APQ8055 fro the Series 2 which is a 1 core up to 1.4 GHz Scorpion: 32K+32K L1, 384K L2 and Media Tech is in competition with them, but everything comes at a price in this world and here the price paid is the battery life of the devices which results in less TOS(Time on Screen). Now to maintain that TOS frequent charging is done hence consumption of power or electricity is more resulting in more use of resources which is a concern for third world countries. We need to reduce that use to some extent. In this paper a simple technique of cascading 2 circuits namely the dark sensor using a light dependent resistor and a charging circuit of a charger using IC7805 voltage regulator is being used. The result is dark charger which can be used to charge when there is no electricity hence increasing the TOS and use of less electricity .

Palanquin, horse, hand-pull rickshaw, paddle rickshaw, tram, bus, auto-rickshaw, and finally today's pollution controlled Bharat Stage (BS) -III-IV bus ----- more or less this is the evolution of passenger transport of Kolkata. Transport demand in most of the Indian cities has increased substantially during last few decades due to increase in population (natural increase and migration from rural areas and smaller towns). Availability of motorized transport, increase in household income, and increase in commercial and industrial activities has further added to it. Unfortunately, public transport systems in Indian cities have not been able to keep pace with the rapid and substantial increase in travel demand.

NREGA – AN IMPERIALIST DESIGN?

Nilanjan Sengupta — Wed, 23 Oct 2019 22:47:45 +0530

The Mahatma Gandhi National Rural Employment Guarantee Act, 2005 (MGNREGA) was notified on September 7, 2005. The mandate of the Act is to provide at least 100 days of guaranteed wage employment in a financial year to every rural household whose adult members volunteer to do unskilled manual work. NREGA was projected as a tool to ensure inclusive growth in rural India through social protection, livelihood security and democratic empowerment.

Most of the government programs like NREGA when actually planned, are very good plans (at least on paper). The government prepares a holistic perspective for the project. From the experience of other schemes, it may be concluded hat when it comes to execution, most of them fail and the NREGA scheme is also no exception. Like any other government schemes, NREGA functions through a Public Distribution System. In that case, loopholes become a part and parcel of the whole execution process. The Beneficiaries are only a very few people.

TECHNICAL EDUCATION AND EMPLOYABILITY

Amitava Sil — Wed, 23 Oct 2019 22:56:12 +0530

With a manpower of over one billion, it is ironic that India suffers from dearth of talent and skill to fulfill the present day need of industry and as a result it is a serious challenge to mitigate shortages of skills required by in industry sector. Study reveals that of the 6 lakhs engineers that graduate annually, only 18% are employable for the software engineer-IT services role, while just 4% are appropriately trained to be directly deployed on projects. For core jobs in mechanical, electronics/electrical and civil engineering profession, only a mere 7.5% to 8% are employable.

Education is a concurrent subject under the purview of the Central Government as well as the State Government. In addition, statutory bodies like All India Council of Technical Education (AICTE) and the University Grants Commission (UGC) have their empowerment by the Acts of Parliament to regulate higher education.

SCIENCE, TECHNOLOGY AND INNOVATION (STI) POLICY 2013: OBJECTIVE ASSESSMENT

Ashik Paul — Thu, 24 Oct 2019 13:19:49 +0530

The Prime Minister Dr. Manmohan Singh unveiled a new Science Technology and Innovation (STI) Policy on the occasion of the centenary year of Indian Science Congress on January 3, 2013 in Kolkata. One of the key goals of the STI policy is to develop science, technology and innovation with focus on faster, sustainable and inclusive development for the people. The policy speaks of

promoting scientific temper amongst all sections of the society,
making careers in science, research and innovation an attractive career option particularly for bright young minds,
establishing world class infrastructure for R&D and increasing India’s contribution to global scientific publications from 3.5% to 7%
creating an environment for enhanced private sector participation in R&D

to mention a few.

In principle, the policy promises significant boost to a largely demoralized science and technology community in the country. However, the methodology to achieve such goals and the possible outcome, if any, on a developing nation like India needs to be studied in greater details. Developing scientific temper among the vast majority of our population is a desirable but difficult target, keeping in view the impact of religion and caste-based policies of some state governments as well as national political forums. The STI-2013 objective of empowering women through appropriate STI inputs comes at a time when proper representations of women in different policy making positions are inadequate. National statistics of women in key government institutions of science and technology present glaring disparity in representation even after more than five decades of independence. This may be expected in a society caught between the idealisms of ‘equal entitlement’ and the glitz and glamour associated with the so-called ‘shining India’ concept. It should be kept in mind that there are not enough calories per head for a vast majority of Indians with 43% of Indian women being anaemic and 67% starved of calories.

Reforms in Power Sector: Introspection

Mriganka Majumdar — Thu, 24 Oct 2019 13:33:37 +0530

A decade has already passed since enactment of Electricity Act 2003. Now the different clauses of the said Act is being amended but it is time to look back and analyze how much the objectives as framed under the said EA 2003 has been achieved and what are amendments needed. At the outset let us look into the process of amendment of EA 2003. EA03 came into effect after prolonged discussions at various levels of stakeholders followed by addition and deletion at draft stage and finally acceptance in parliament. The entire process took almost 10 years before declaration of EA03. Its true that all sort of act , rules and regulations need to be reviewed and re-addressed in subsequent time and necessary amendment are to be made based on policy implementation and objective of successful and effective impact on socio-economic condition. But such process of review and amendment shall be a continuous one particularly when EA03 was totally a new concept and approach with an objective for development of power system based on optimal utilization of all resources having far reaching impact on socio-economic development.

Food Security: Indian Perspective

Joy Chakraborty — Thu, 24 Oct 2019 13:49:04 +0530

The issue of Food security, climate change, and environmental problems are all closely related to each other. Our economy is agro-based economy. So here, agricultural sector plays a pivotal role. Draft National Food Security Bill was introduced 2years ago. The Supreme Court of India has declared right to food as a fundamental right to life. Since independence, series of measures have been taken by the Govt. However, the number of undernourished persons have increased from 210 million in 1992 to 252 million in 2004-06. India is about half of the worlds’ undernourished children. India’s position is deteriorating day by day. Government of India fixed a quantity of 35 kg. of food grain per head per month for the people staying below poverty line. Actual determination of the poor people is very confusing. Different institutions ( National & International) in different time introduces various measures to determine the extent of poverty and to find out the no of poor people. According to World Bank standard the people whose earnings are $1.25 per day are included in the group of Extremely poor and the group of people whose earnings are $2 per day are counted as Moderately poor. In India it is assumed that 50% people are lying under poverty line ( N.C. Saksena committee report ). According to Tendulkar committee report, 42 % of people in our country are lying under the poverty line. After so many years of study, it has not been decided that how many persons are lying below the poverty line actually. According to the Planning Commission, in Rural area , people whose earnings are <Rs. 750 per month & in urban area < Rs. 870 per month are lying below the poverty line. There is not a big difference among the condition of the people who lies below the poverty line or just above the poverty line.

SEEKING APPROPRIATE ALTERNATIVE FOR SUSTAINABLE DEVELOPMENT - A CASE FOR RESPONSIBLE ARCHITECTURE

Anjan Mitra — Thu, 24 Oct 2019 14:55:38 +0530

“Sustainable Development” – a notion that has become almost a cliché, What is really sustainable? From which perspective it is considered and how it can be translated – are the questions that the designers are seeking today. After thirty years of search we have arrived at an understanding of sustainability as a practice, which goes beyond cost optimisation, affordability, technological innovation, energy consciousness, environmental sensibility and cultural conservation. All these issues are reflected in the art of Building, the Process of Design and sensible architecture. It must be a responsible gesture on the part of the architects/ Designers to consciously think and activate and induce the process of Sustainability. It is a holistic concept that we are embarking to figure out the right alternative for a specific use, site or context and client or its direct beneficiary. This is a process driven approach and therefore flexible, dynamic and adaptable.

WATER – ENERGY NEXUS: ROLE OF SOLAR ENERGY

Sampa Chakraborty — Thu, 24 Oct 2019 15:30:11 +0530

To address the interrelated crises of the energy and the environment, solar energy should be used for wastewater treatment. This review summarizes the various techniques of using solar energy for getting usable water from sea water and wastewater. A part of the contents of this paper was presented in a lecture delivered at a programme of FOSET on June 21, 2013

The HT Capacitor Bank Shunt Compensation

Sandip Boral, Joydeep Dasgupta, Rupak Biswas — Mon, 02 Sep 2019 00:00:00 +0530

In Sub-Transmission & Distribution system the significance of HT Capacitor Bank is increasing day-by-day for Shunt compensation. In West Bengal the premier power utility had taken an initiative for installation of HT Shunt Capacitor Banks at 11kV bus of 33/11kV substations. The main motto has been to improve the p.f. under Maximum demand conditions and subsequently improvement of voltage profile by reducing the huge network losses. Thus a part of today’s increasing demand can be served, keeping the same Generation & Transmission capacity and consequently, more revenue can be earned. A systematic approach for designing the shunt compensation system along with post commissioning results have been presented herewith as case study basis.

UTILISATION OF BIO-CHEMICAL PROPERTIES OF JUTE IN CONVERSION OF NON-ARABLE LATERITIC WASTELANDS

Samya Sengupta — Thu, 24 Oct 2019 15:12:18 +0530

Jute can be effectively used for conversion and reclamation of lateritic wastelands of our country to make them arable. It is a widely grown natural biodegradable, eco-friendly and cost-effective fibre. Jute contains useful chemical substances like lignin, hemi-cellulose, alpha-cellulose and other cellulose derivatives, which make significant contribution to pest-resistant and water retention properties of soil. They help to regulate the Carbon and Nitrogen cycle in the soil and also attract bacterial agglomeration.

We, on behalf of a voluntary organisation, carried out an experimental work at a lateritic wasteland at Garhbeta of Paschim Medinipur District of West Bengal to check soil erosion and improve fertility of land using jute geotextile. The soil has very low carbon and nitrogen content and is acidic in nature having no or very poor vegetation growth. After the experiment the land erosion has been completely restricted and due to bio-degradation of jute, the nitrogen and carbon content of the soil have increased considerably. The denuded wasteland has now become fertile and arable. The soil is gradually attaining the character of a ‘medium soil’ from a ‘very poor’ soil. The method is easily adoptable, cost-effective and eco-friendly as it uses only jute as the component for conversion of the land.

This paper has tried to correlate the unique bio-chemical properties of jute with the agricultural and geological findings of the field-trial.

Growth of housing sector in India

Nilanjan Sengupta — Mon, 28 Oct 2019 23:33:22 +0530

Building construction sector can play a major role in reducing Greenhouse Gas emission through application of technologies aimed at reduction of use of building materials. Energy consumed during production of building materials and components plays a crucial role in creating environmental pollution. India is witnessing high growth in urban and rural housing, which needs more production of building materials. Permanent or semi-permanent type buildings which consume easily available conventional materials like brick, reinforced cement concrete etc. can be made Economic and Eco-friendly by lowering use of energy-consuming building materials through Cost-effective Construction Technologies. Buildings with Cost-effective Construction Technology can be designed within the parameters of the existing Indian Standards. Awareness generation among the users, proper technical and architectural guidance and easy availability of skilled manpower are of utmost importance for promotion of cost-effective technologies in India and to make them as the most acceptable case of sustainable building technologies both in terms of cost and environment.

Use of Piper Betel to combat COVID19

Partha Sarathi Sengupta — Sat, 11 Apr 2020 20:47:33 +0530

Chymotrypsin like protease is a ratified target in the design of potential anticoronavirus inhibitor. In a recent research conducted by TCS, India 31 molecules out of 1600000 have been identified as the most effective protease inhibitors against COVID 19. One of those is Aurantiamide, a plant constituent derived from ‘Piper aurantiacum‘, mostly available in India, Nepal, Vietnam, Thailand and other Asian countries. Still the process is under in vitro state. This “Aurantiamide” in the form of Aurantiamide acetate has anti-cancer, anti-inflammatory and antinociceptive activities as yet traced. The combined application of Hydroxychloroquine and Azithromycin is reported as a treatment of COVID 19 till now. This article is on the usage of Piper Betel leaf as a potential herbal medicine to grow human body’s self defence mechanism against either the reception of such pathogens or in viral load reduction of affected patients.

Effect of immunomodulatory action of iodine and natural supplements in preventing covid19 acquisition and preventing covid related complications

Dr Pranab Mallik, Dr Samya Sengupta — Wed, 17 Jun 2020 21:26:12 +0530

COVID-19 can be considered primarily a disease of the lower to upper middle class affluent group of population. Residents of slums, transient footpath dwellers who survive on a measly diet of rice and common salt are less affected. In contrary, the affluent population with their daily quota of bread, pastries, aerated drinks, in spite of better sanitation and hygiene succumb to the disease. Hence the provision of dietary iodine must be taken seriously and any form of dietary iodine depletion by agents like potassium bromide exerts a negative immunomodulatory effect causing easy COVID acquisition and COVID related complications.

AUTISM – THE GRIEVANCE OF GENE

Dr Pranab Mallik — Tue, 20 Oct 2020 00:00:00 +0530

"OTHERISATION OR MARGINALIZATION OF AUTISTIC CHILDREN" - this is the 'Festering Wound', that I have been combating with, regarding myself an observer of Autistic children. It's been years, that I have been embracing my Autistic children -evaluating, assessing, consulting, treating them while deciphering their unuttered pain or discomfort. While dealing with the sky-rocketing cases of Autism, and considering the 'Vaccines', as one of the responsible factors behind Autism, I have been asked a glaring question, innumerable times. If vaccines are the compelling factors of Autism, then why every child is not affected by Autism while everyone is being vaccinated? My answer is if a child gets vaccinated and he has a strong history of OCD and BIPOLAR DEACTIVITY among the members of his family, then he easily becomes a victim of Autism or complex neurological Dynamic disorder.

We have not penned this for disdaining or attacking people with OCD and Bipolar Deactivity. Here are just some observations, which lead to a conclusion Autism is the revenge of Gene or GRIEVANCES OF GENE.

Integrated Editorial Services, Conference Management System along with pre-print archiving for protection of copyright of articles, case studies, concept notes, etc.

Nilanjan Sengupta — Mon, 26 Sep 2022 11:09:06 +0530

There are several available packages like ‘Editorial Manager’, ‘Scholer One’, ‘Easy Chair’ etc. which provides a platform for Editorial Services to the journals and also Conference Management System including preparation of proceedings for conferences. Apart from those there are several other packages used all over the world and some journals accept submission of papers directly to their emails or other appropriate systems of their own. Some industrial bodies, corporate houses, organisations publish their own magazine / journal also by collecting articles, case studies, concept notes etc. by email.

Incidents of copying from other person’s articles, case studies, and concept notes without acknowledgement are gradually increasing with the advent of information technology and easy availability of unprotected articles in the net. In some cases the entire article is phished out before publication in an unscrupulous manner without the knowledge of the original author. There were incidents where articles were phished out from some journal’s editorial office when those were under review/revision. Due to this malpractice the original authors, inventors, or persons who conceptualised some novel ideas lose their copyright on their original hard work.

Therefore it is felt needed to develop one Integrated Editorial Services and/or Conference Management System along with protection of copyright of articles, case studies, concept notes, etc.
