Energy Supply Chain of Co-Firing system to generate electricity
The problem of air pollution on the streets of the national capital of India, New Delhi is a major concern. Majority of the pollutants are generally originated from either the vehicles on the roads or the burning of crops from the neighbouring states of the National Capital Region (NCR). To improve the condition of the air quality by the vehicles, implementation of the Electric Vehicles (EVs) in an energy supply chain is a suitable plan. The objective of this paper is to plan a supply chain of generation of electricity by the process of co-firing that prompts benefits both in blend of innovation utilized and financial process duration. The most easily available renewable source of waste is biomass and utilizing it to produce electricity can be a great alternative to the traditional sources of energy. So, the process of co-firing can be done to generate electricity. Combustion on renewable resources leads to less discharge of carbon and more ecological atmosphere. Co-firing biomass has gained international attention and interest in recent past as it is environmentally friendly and economical as both the fuels used can be combusted in same atmosphere. A model of an energy process is analysed and is concluded that the usage of Electric trucks (Tesla Semi) instead of conventional trucks would reduce the carbon footprint and the whole energy supply chain is studied and the cost analysis of the process is explained. The cost of the plant with the baseline method of transportation with the conventional trucks is greater than that of cost of plant with electric trucks (Tesla Semi)
INFORMATION NEEDS AND SEEKING BEHAVIOUR OF AGRICULTURAL COMMUNITY OF ATTABIRA AREA OF BARGARH DISTRICT, ODISHA: A SURVEY
The study on the information-seeking behavior of the agricultural community was undertaken in the attabira area of bargarh district of Odisha with objectives to study the different areas in which they require information frequently and determine the sources through which they rely on. It was found that most of the people are dependent upon agriculture in the attabira area. They started working at the age of 18. Most of the farmers (85.6%) of farmers opted for pooja seeds for cultivation. The study shows 7.36% of the respondents are facing difficulties in irrigation facilities. About 78.9% of the people are talking about MSP (Minimum support price). About 7.3% of farmers gathered information from social media, TV, Call centers, etc. It is observed that the highest numbers of people are talking from a nationalized bank. The farmers were getting information from various sources like TV media, print media, etc. The library plays a crucial role in the dissemination of knowledge. The farmer knowledge center was established where they could get their query solved. The knowledge centers need to provide the right information at the right time in a personal way. The result reveals that a large number of people of the attabira district are influenced by socio-economic variables
A comparative analysis of hydrochlorothiazide and chlorthalidone induced hyponatremia at the dose commonly prescribed in clinical practice
Background: Despite the differences in cardiovascular outcomes, pharmacokinetics, pharmacodynamics, the diuretics, chlorthalidone (CTD) and hydrochlorothiazide (HCTZ) are often considered as interchangeable. There is an on-going debate whether CTD should be preferred over HCTZ, because it appears to be more effective in the prevention of cardiovascular events. The relative difference in the incidence of hypokalemia and hyponatremia, is also a topic of debate. With this background, the study was carried out to compare the prevalence of hyponatremia between CTD and HCTZ used in the treatment of hypertension at the dose commonly prescribed in clinical practice.Methods: This was a cross sectional study carried out on a convenience sample of 74 adult patients with provisional diagnosis of hyponatremia or with a plasma sodium level of less than 135mmol/L and having a history of anti-hypertensive use of HTCZ or CTD in the dose range of 12.5-25mg/day and 6.25-12.5mg/day respectively. Chi square test and independent samples ‘t’ test were used analyse the results in GraphPad Prism 6.0.Results: HCTZ was found to be the preferred diuretic in hypertension, whereas CTD was preferred in the age group of 65-74 years. The symptoms indicative of hyponatremia as well as a lower plasma sodium level were more common in the HTCZ treated group. Patients of hypertension using CTD were less predisposed to hyponatremia (OR 0.804, 95% CI 0.207-3.12).Conclusions: Chlorthalidone, when used at a lower dose of 6.25-12.5mg/day for the treatment of hypertension cause a lesser risk of hyponatremia than hydrochlorothiazide
Relating the curvature of De Sitter Universe to Open Quantum Lamb Shift Spectroscopy
In this paper, we explore the connection between the curvature of the
background De Sitter space-time with the spectroscopic study of entanglement of
two atoms. Our set up is in the context of an Open Quantum System (OQS), where
the two atoms, each having two energy levels and represented by Pauli spin
tensor operators projected along any arbitrary direction. The system mimics the
role of a pair of freely falling Unruh De-Witt detectors, which are allowed to
non-adiabatically interact with a conformally coupled massless probe scalar
field which has the role of background thermal bath. The effective dynamics of
this combined system takes into account of the non-adiabatic interaction, which
is commonly known as the Resonant Casimir Polder Interaction (RCPI) with the
thermal bath. Our analysis reveals that the RCPI of two stable entangled atoms
in the quantum vacuum states in OQS depends on the de Sitter space-time
curvature relevant to the temperature of the thermal bath felt by the static
observer. We also find that, in OQS, RCPI produces a new significant
contribution appearing in the effective Hamiltonian of the total system and
thermal bath under consideration. We find that the Lamb Shift is characterized
by a decreasing inverse square power-law behavior, , when inter atomic
Euclidean distance, , is much larger than a characteristic length scale,
, which is the inverse surface gravity of the background De Sitter space. If
the background space-time would have been Minkowskian this shift decreases as,
, and is independent of temperature. Thus, we establish a connection
between the curvature of the De Sitter space-time with the Lamb Shift
spectroscopy.Comment: 65 pages, 3 figures, 1 Table, This project is the part of the

Clinical epidemiology and treatment outcome of Hexaconazole poisoning – A prospective six year study
Background: Hexaconazole is a category 3/4 of poison as per the W.H.O Expert Group on Pesticide Residues. Hexaconazole is used to control infection by fungi in paddy and other crops. Apart from destroying the target species, it can also cause damage to humans. There have been discrete reports of instances of human poisoning due to hexaconazole. Methodology: A patient record-based cross-sectional study was carried out in Konaseema Institute of Medical Science & Research Foundation, Amalapuram, Andhra Pradesh, India during a period from March 2014 to April 2020 on 26 confirmed cases of hexaconazole poisoning. The clinic-demographic data, hematological, and biochemical parameters at the time of admission and at 72 hrs as well as the outcome were recorded and analyzed using descriptive statistics and paired t test. Result: The prevalence of hexaconazole poisoning was 4.79% of all poisoning cases. The major clinical presentation was gastrointestinal symptoms with vomiting being commonest. There was no significant change in the biochemical and hematological parameters. The mean duration of hospitalization was 4.93+1.39 days. The recovery rate was 100% without any major sequel. Conclusion: Poisoning due to hexaconazole is uncommon in comparison to poisoning by other pesticides in the agricultural community. The clinical manifestations of hexaconazole poisoning indicated that it is of non-serious nature and its recovery was without any sequel
Parallel energy-efficient coverage optimization using WSN with Image Compression
Energy constraint is an important issue in wireless sensor networks. This paper proposes a distributed energy optimization method for target tracking applications. Sensor nodes are clustered by maximum entropy clustering. Then, the sensing field is divided for parallel sensor deployment optimization. For each cluster, the coverage and energy metrices are calculated by grid exclusion algorithm and Dijkstra’s algorithm, respectively. Cluster heads perform parallel particle swarm optimization to maximize the coverage metric and minimize the energy metric. Particle filter is improved by combing the radial basis function network, which constructs the process model. Thus, the target position is predicted by the improved particle filter. Dynamic awakening and optimal sensing scheme are then discussed in dynamic energy management mechanism. A group of sensor nodes which are located in the vicinity of the target will be awakened up and have the opportunity to report their data. The selection of sensor node is optimized considering sensing accuracy and energy consumption. Experimental results verify that energy efficiency of wireless sensor network is enhanced by parallel particle swarm optimization, dynamic awakening approach, and sensor node selection
Effect of sitagliptine and vildagliptine on carotid intima/media thickness in patients with type 2 diabetes mellitus
Background: Atherosclerosis is a known macro-vascular complication of diabetes mellitus. Gliptins, as a drug class have non-glycemic beneficial action on blood vessels and in addition to their anti-diabetic effects. This study was carried out to find out the effects of sitagliptin and vildagliptin on common carotid intima-media thickness in patients with type 2 diabetes mellitus.Methods: The observational longitudinal study was carried out on 100 patients with 80 patients with confirmed clinical diagnosis of type 2 diabetes mellitus. They were divided in 3 groups. Group A and Group B received drugs, either sitagliptine or vildagliptin and Group C control group did not receive any drug. High resolution B-mode ultrasonography was carried out for the measurement of intima-media thickness (IMT) of both the common carotid arteries (CCA). Data analysis was done using Microsoft excel spreadsheet and GraphPad Prism version 7.0 (free trial version) software package. A p value of ≤ 0.05 was considered as statistically significant.Results: The baseline value for the control group was 0.812±0.0748 mm for both the right and left CCA. At 52 weeks the CCA IMT for the right and left CCA were 1.0185± 0.272 mm and 0.936±0.149 mm respectively. At 104 weeks the CCA IMT for the right and left CCA were 0.923±0.243 mm and 0.859±0.123 mm respectively.Conclusions: There was a significant decrease in carotid intima-media thickness in patients of type-2 diabetes mellitus treated with sitagliptin and vildagliptin
Indirect detection of Cosmological Constant from interacting open quantum system
We study the indirect detection of Cosmological Constant from an open quantum
system of interacting spins, weakly interacting with a thermal bath, a massless
scalar field minimally coupled with the static de Sitter background, by
computing the spectroscopic shifts. By assuming pairwise interaction between
spins, we construct states using a generalisation of the superposition
principle. The corresponding spectroscopic shifts, caused by the effective
Hamiltonian of the system due to Casimir Polder interaction, are seen to play a
crucial role in predicting a very tiny value of the Cosmological Constant, in
the static patch of de Sitter space, which is consistent with the observed
value from the Planck measurements of the cosmic microwave background (CMB)
anisotropies.Comment: 27 pages, 7 figures, This project is the part of the non-profit

Circuit Complexity From Cosmological Islands
Recently in various theoretical works, path-breaking progress has been made
in recovering the well-known Page Curve of an evaporating black hole with
Quantum Extremal Islands, proposed to solve the long-standing black hole
information loss problem related to the unitarity issue. Motivated by this
concept, in this paper, we study cosmological circuit complexity in the
presence (or absence) of Quantum Extremal Islands in the negative (or positive)
Cosmological Constant with radiation in the background of
Friedmann-Lematre-Robertson-Walker (FLRW) space-time i.e the presence
and absence of islands in anti-de Sitter and the de Sitter spacetime having
SO(2, 3) and SO(1, 4) isometries respectively. Without using any explicit
details of any gravity model, we study the behaviour of the circuit complexity
function with respect to the dynamical cosmological solution for the scale
factors for the above-mentioned two situations in FLRW space-time using
squeezed state formalism. By studying the cosmological circuit complexity,
Out-of-Time Ordered Correlators, and entanglement entropy of the modes of the
squeezed state, in different parameter spaces, we conclude the non-universality
of these measures. Their remarkably different features in the different
parameter spaces suggest their dependence on the parameters of the model under
consideration.Comment: 75 pages, 29 figures, 4 tables, Dr. Sayantan Choudhury would like to

Knowledge, practices and influencing factors defining unhealthy food behavior among adolescents in India: a scoping review
Unhealthy food behaviors are the major contributing factors to the rising burden of non-communicable diseases (NCDs) among adolescents in India. Knowledge and practices related to unhealthy eating are significant factors influencing adolescents’ food behavior. In this scoping review, we aim to map evidence and identify gaps on knowledge, practices, and the influencing factors associated with unhealthy food behavior among Indian adolescents by examining the existing literature. Arksey and O’Malley’s scoping review framework and the Joanna Briggs Institute Reviewers’ manual were used for this review. After the screening, 33 articles were identified according to the inclusion criteria. Data extraction was performed according to the study objectives, followed by narrative summarization. The studies included a total of 20,566 adolescents. Most studies reported insufficient knowledge about healthy food choices among adolescents. Diet intake patterns among the adolescents showed a lower amount of fruits and vegetables and an increase in fried items, sugar-sweetened beverages, packaged food, and fast food in both sexes, with a broader association with peer influence (21.2%), parental unhealthy food behavior (15.1%), place of residence (6.06%), emotional status (6.06%), and mass media exposure (18.1%). The scoping review highlights the need for targeted interventions aimed at improving the knowledge and practices of Indian adolescents by promoting healthy food choices and sensitizing them about the risk of non-communicable diseases. The analysis of evidence around adolescent dietary behavior in India shows a monotonous, limited, and narrow range in scope, indicating the extended need for research
