Abstract
In a decentralized network every user makes use of personal identity details at different places for various services and these details are shared with third-parties without their consent and stored at an unknown location. Organizations like government, banks and social platforms are considered to be the weakest point in the current identity management system as they are vulnerable which leads to compromising billions of user identity data. Block chain based User Identity Management is a solution which provides a decentralized environment that manages the user identity data and their related Know-Your-Customer (KYC) documents in a distributed ledger. All the transactions of the network are stored in the block which is a type of a data structure and these blocks are validated using the powerful consensus algorithms and linked to form a block chain. Smart contracts will act as an interface between the client and the block chain network. User’s information cannot be provided to any third party vendors without the explicit consent of the user. This paper proposes a framework for User Identity Management using Block chain technology in a decentralized Network. The proposed framework ensures a high level privacy and security for the personal identity details and the documents. In addition to that the performance analysis of the framework is presented in terms of Transaction, Mining Resource and Difficulty Variation.
Determination of safety factor for rock mass surrounding tunnel by sudden change of equivalent plastic strain in strength reduction method

Published: July 2021

Abstract
A safety factor of rock mass surrounding the tunnel can be determined using the strength reduction method (SRM), however, it is the most important to solve the criterion of critical state. For the stability estimation of rock mass surrounding tunnel, there is need to discuss that it is preferable to use the same criteria for the slope, such as non-convergence of finite element calculation, penetration of plastic strain and sudden change of horizontal displacement. A safety factor can be determined by sudden change of equivalent plastic strain in relationship between a reduction coefficient of strength parameter and equivalent plastic strain. This method is based on the elasto-plastic FEM and the SRM by ABAQUS and Mohr-Coulomb yield criterion. Simulation results using this method show how a safety factor varies with geometries, friction angles and cohesions for circle and square tunnels. Simulation results also show a safety factor varying with quality change of rock mass, pore water pressure and tunnel depth.

Abstract
The web-based supported collaborative learning is increasingly used to support student social activities in higher institutions. However, little is known about the factors of collaborative learning in a web-based supported learning environment. Therefore, this study examines the use of a web-based supported collaborative platform to enhance project-based student engagement. This research aims to determine the factors that determine collaborative learning and subsequent student satisfaction. Moreover, this research determines students' cognitive load understanding, social influence, and learner's motivation towards collaborative learning and the resultant impact of the web-based supported collaborative platform on student satisfaction. The data was collected from university post-graduate students who used the TRELLO platform. A total of 115 post-graduate students participated in this study, and the resulting data were analyzed based on partial least squares structural equation modelling statistical approach. The study results suggest that students’ social influence and motivation positively influence collaborative learning; directly and indirectly, students are satisfied with the use of a web-based supported collaborative learning platform to support project-based student engagement.

Abstract
Rheumatoid arthritis an autoimmune infectious disorder, is categorized by inflammation and increased level of pro-inflammatory cytokines which are released by immune cells, macrophages or activation of arachidonic acid metabolism. The expression of these cytokines, oxidative free radicals and the activation of COX-2 enzymes are crucial targets for chronic inflammation. On the basis of established anti-inflammatory efficacy of Nerolidol, the primary study was further appraised to determine its efficacy against Freund’s complete adjuvant (CFA) rheumatoid model. Arthritis was persuaded by inoculation of 0.1mL CFA injection into left hind footpad of rats. Anti-arthritic potential of nerolidol (at 200, 400 and 800mg/kg doses) was assessed by measuring the paw volume, body weight, serum analysis, histopathological and radio-graphics of ankle joints. Expressions of cytokine’s panels like IL-10, IL-4, COX-2, NF-Kβ, TNF-α, IL-6, PGE-2 and IL-1β were determined by real time qPCR. Antioxidant enzyme analyses was calculated by measuring the SOD, POD and catalase activity from serum and equated with arthritic control group. Nerolidol prevented the body weight loss, stabilized the biochemical and haematological homeostasis and significantly reduced the paw volume. Furthermore, X-ray and histopathological assessment of ankle joints showed an improvement in the joint structure of rats treated with nerolidol. Besides that, over expression of gene pointers like TNF-α, IL-1β, IL-6, NF-Kβ, PGE-2 and COX-2 in CFA treated control rats were also reversed with nerolidol. This anti-arthritic mechanism was further supported by the increased level of IL-10, IL-4 and serum anti-oxidant activity. The present findings demonstrate that nerolidol reduce the adjuvant arthritis by down-regulating the proinflammatory cytokines and up-regulating the aforementioned anti-inflammatory cytokines and may be used as a therapeutic substance for the management of human rheumatoid arthritis.

Abstract
IntroductionBone involvement in Gaucher disease can affect quality of life. Different bone involvements can be confused with hematological diseases, infections and malignancy.CaseOur patient with bilateral femur involvement presented to us with a pathological fracture. After the pathological fracture was treated with a long leg splint and healed, we performed biopsy on our patient because of suspicious radiological findings. The pathology results reported gaucher disease with bone infiltration, during the time in which conservative follow up was taking place, eventually leading to the patient’s mobilization again.ConclusionThe bone findings of gaucher disease portray a difficult process that requires follow-up and treatment. It is crucial to scan patients periodically for possible vertebral and extremity symptoms. Vertebral and extremity fractures are situations that undoubtly require experience as they can imitate malignant masses.

Published: July 2021

Abstract
In this paper, an n-star general dynamic model of tethered satellite system with closed-loop configuration is provided. An analytical method for periodic solution stability of the general dynamic model is proposed based on Floquet theory, which proved that the periodic solution stability of the system depends on the maximum modulus for the eigenvalue of a matrix related to the Jacobian matrix. The periodic solution stability of a 3-star system with equilateral triangle as the initial configuration is analyzed as an example based upon the analytical method. The critical stable spin angular velocity of the 3-star system is analyzed when the system spins clockwise, and its numerical simulation is carried out to verify the results. The results show that the analytical method of periodic solution stability can solve the critical stable spin angular velocity accurately of the tethered satellite system, and the 3-star system can guarantee stable spin when the spin angular velocity is about 2.1 times of its revolution angular velocity, otherwise the disturbed system will not be able to re-converge to the initial configuration in finite time.

Abstract
Background: Adaptation to Non-Invasive Ventilation (NIV) in Amyotrophic Lateral Sclerosis (ALS) is generally implemented in an inpatient or outpatient setting.Aims: To investigate whether adaptation to home-based NIV is as effective as outpatient one in ALS in terms of arterial carbon dioxide (PaCO2) improvement. We also evaluated as secondary outcomes NIV acceptance, adherence and patient/caregiver satisfaction, quality of life (QoL) and caregiver burden.Methods: Sixty-six ALS patients with indication for NIV were randomly assigned to two groups: 34 underwent NIV initiation at home (Home Adaptation, HA) and 32 at multiple outpatient visits (Outpatient Adaptation, OA). Respiratory function tests were performed at baseline (T0) together with blood gas analysis, which was repeated at the end of adaptation (T1) and after 2 and 6 months from T1. Overnight cardiorespiratory polygraphy was performed at T0, T2, and T3. NIV acceptance (≥5 hours/night for 3 consecutive nights) and patient's and caregiver's expertise to manage NIV by an educational learning test were measured at T1; NIV adherence (≥150 hours/month) was measured at T2 and T3. Short Form Health Survey (SF-36), Caregiver burden Inventory (CBI), Caregiver burden scale (CBS) and Zarit Burden Interview (ZBI) were performed at T0, T2 and T3.Results: Fifty-eight participants completed the study. No significant differences were found between groups in PaCO2 at T1 (p=0.46), T2 (p=0.50) and T3 (p=0.34) as in acceptance (p=0.55) and adherence to NIV at T2 and T3 (p=0.60 and p=0.75, respectively). At T2, the patients’ QoL, assessed with SF-36, was significantly better in HA than OA (p=0.01), but this improvement was not maintained up to T3 (p = 0.17). Conclusions: In ALS, adaptation to NIV in the patient’s home is effective as that performed in an outpatient setting, in terms of PaCO2 , acceptance and adherence. Improvement in quality of life was also found to be greater at home only after adaptation, opening the need for further studies to understand the role of environment with respect to NIV adherence.

Published: July 2021

Abstract
A mathematical model of an ultrahigh sensitivity piezoresistive chip of a pressure sensor with a range from -0.5 to 0.5 kPa has been developed. The optimum geometrical dimensions of a specific silicon membrane with a combination of rigid islands to ensure a trade-off relationship between sensitivity (Ssamples = 34.5 mV/kPa/V) and nonlinearity (2KNL samples = 0.81 %FS) have been determined. The paper also studies the range of the membrane deflection and makes recommendations on position of stops limiting diaphragm deflection in both directions; the stops allow for increasing burst pressure Pburst up to 450 кPa. The simulated data has been related to that of experimental samples and their comparative analysis showed the relevance of the mathematical model (estimated sensitivity and nonlinearity errors calculated on the basis of average values are 1.5% and 19%, respectively).

Published: July 2021

Abstract
The anthropogenic environmental pollution generated during the last decades led to significant consequences for the aquatic ecosystems and to potential risks for human health. For this reason, the research has been focused on studying and develop pollutants-removing technologies. Nowadays, despite the presence of performing techniques applied in e.g. the potabilization and waste-water treatments, new strategies aimed to better meet the industrial needs and the environmental requirements are still widely investigated. In this frame, the pollution caused by the presence of anionic species in water, is still not completely solved. For this reason, this work is focused on studying novel cationic maltodextrin-based adsorbents obtained via sustainable approach, for water treatment applications. The adsorption performances towards nitrates-, sulphates- and phosphates-polluted water solutions have been tested and discussed.

Abstract
In this study, heat storage-based hybrid greenhouse dryer has been developed and analysed for drying bitter gourd flakes under the climatic condition of Ranchi, India. The propose heat storage based hybrid greenhouse dryer consists of a solar air heater with 2.12 m2 area, greenhouse dryer and DC fan to induce and force the air. The significant objective of the present study is to analyse the drying efficiency, drying kinetics, property analysis, economic analysis, embodied energy and CO2 mitigation of the hybrid greenhouse dryer for drying of bitter gourd flakes. An experiment was performed simultaneously on proposed system and open sun drying for the proper comparative analysis. The results show that the mass of crop reduced from 4000g to 458g in 6 hr in proposed dryer and 4000g to 500g in 15 hr for open system. Thus, significant drying time is reduced in proposed system by 8 hours as compared to open system. Environmental impact analysis shows that the EPBT was found to be 0.4907 years only. The cost analysis of the proposed system dryer was 22664.30 INR. The total embodied energy is found to be 1591.07 kWh and earned carbon credit ranges from 16844.76 INR to 67379.05 INR, while CO2 mitigation was 46.28 tonnes for 35 years of expected lifetime. Seven standard mathematical models for drying of bitter gourd flakes were studied. Ahmad and Prakash model was found to be best as compared to other models. The metal contents of dried bitter gourd flakes were also examined. Bitter gourd dried in proposed dryers possesses superior metal content as compared to open system. Impact analysis demonstrates that the hybrid greenhouse dryer is more suitable for reducing post-harvest loss with environmental sustainability.

Published: July 2021

Abstract
Background

Covid-19 has quickly become a global health emergency. This infection can cause damage to various organs. Injury to myocardial cells is one of the most important manifestations of Covid-19. The clinical course and outcome of Acute Coronary Syndrome (ACS) are influenced by a variety of factors, including comorbidities and concomitant diseases. One of these acute concomitant diseases is Covid-19 which can affect the clinical course and outcome of acute Myocardial Infarction (MI).
Methods

In this cross-sectional study, the clinical course and outcome of MI and some of its effective factors in patients with and without Covid-19 were compared. 180 patients (129 males and 51 females) with the diagnosis of acute MI were included in the study. 80 patients of them had Covid-19 infection at the same time.
Results

Increase rate in creatinine, arrhythmia, and need for CPR (cardiopulmonary resuscitation) was significantly higher in the Covid-19 group (p value in all three cases < 0.001). Although decline in left ventricular EF (Ejection Fraction) was similar in both groups, the incidence of death was significantly higher in the Covid-19 group.
Conclusions

Based on this information, it appears that patients with ACS who are co-infected with Covid-19 infection need more essential care.

Abstract
Background: The length of time for clinical improvement of patients with thymomatous myasthenia gravis (MG) after extended thymectomy is not clear. The purpose of this study was to determine the length of time after thymectomy in patients with thymomatous MG to achieve a 3-point reduction of Quantitative Myasthenia Gravis Score (QMGS), and identify variables associated with a failure to achieve the reduction. Methods: The records of patients with thymomatous MG who underwent extended thymectomy from January 2005 to December 2018 were retrospectively reviewed. The primary end point was a reduction of 3 points of QMGs and the secondary end point was another reduction of 3 points of QMGs. Results: A total of 481 patients were included in the analysis, the mean age of the patients was 41.63 ± 8.55 years, and approximately 60% were male. The median time to achieve a 3 point decrease in QMGS was 6 months, and the median time to achieve another 3 point decrease was 30 months. Multivariable analysis indicated that age ≥ 42 years and Masaoka-Koga stage > I were associated with a lower probability of achieving a 3 point decrease in QMGS (HR = 0.55 and 0.65, respectively). Likewise, multivariable analysis indicated that age ≥ 42 years and Masaoka-Koga stage > I were associated with a lower probability of achieving a second 3 point decrease in QMGS (HR = 0.53 and 0.53, respectively).Conclusions: In patients with thymomatous MG who receive thymectomy, age ≥ 42 years and Masaoka-Koga stage > I are associated with a worse prognosis and failure to achieve a 3 point decrease in QMGS.
