A New Cryptographic Encryption Approach for Cloud Environment

Cloud security and trust management are an important issue in the cloud environment. Cloud computing is the result of the evolution of virtualization, service-oriented design, and the widespread adoption of involuntary and utility computing. Today, cloud computing is the fastest growing technical term and captures a global service-oriented market, so cloud computing service providers and cloud computing consumers need to maintain trust between them. In cloud security, if you discuss the security procedures of traditional IT information systems, designing security into cloud software during the software development life cycle can greatly reduce the cloud attack surface. With cloud computing providing Security as a Service (SAAS), security software is an important issue. From a cloud customer perspective, the use of security services in the cloud reduces the need for security software development. The requirements for security software development are transferred to the cloud provider. This work proposes a new cloud environment security and trust management algorithm, which uses the cryptosystem method to improve the single alphabet based on the concept of multi-letter cipher. Encryption and decryption is applied to plain text to encrypt text and cipher text for plain text conversion. In this work, the algorithm's power consumption, encryption and decryption throughput, and security analysis are also presented

CONCEPT OF AHARA (DIET) IN AYURVEDA: A CRITICAL REVIEW

Ahara is first among the three significant pillars of Ayurveda. It means that it is one of the fundamental principles ahead which gives health, happiness and harmony along with the nature. One should regularly take such substances which are conductive to the preservation of good health and are able of avoid the attacks of sickness. Such type of diet is called naturally healthy diet. Ayurveda is science of life. Main aim of Ayurveda is to maintain health of a person. Ahara plays importance role to achieve this target. In the modern times, the ways in which the food is prepared and presented have changed drastically. Because of the rapid swiftness of life style towards urbanization, one can have less access to fresh food. Today, the dependency on packaged and processed food has also increased exceptionally. It definitely has some destructive effect on both mental and physical well-being. Today Due to consumption of unwholesome diet society facing so many types of disease. Here the concept of Ahara according to Ayurveda is described.

Molecular Interaction Studies of Aqueous Acetonitrile Solutions Using Ultrasonic Technique

Density (ρ), viscosity (η) and ultrasonic velocity (u) of aqueous acetonitrile solutions were measured as functions of concentration at 308.15K. The measured data of ρ, η and u have been used to calculate various acoustical and thermodynamic parameters viz. adiabatic compressibility (β ad ), intermolecular free length (L f ), acoustic impedance (Z), relaxation time (τ), rao’s constant (R M ), wada’s constant (W), free volume (V f ), absorption coefficient (α/f 2 ), gibb’s free energy (∆G), relative association (R a ) and available volume (V a ). These parameters help out in elucidating the molecular association in the mixture. The variation of these parameters with concentration of solute indicates the nature of interaction present in the binary mixtur

A study of acoustical parameters of cupric oxide nanoparticles dispersed in aqueous solutions of various glycols

In this study cupric oxide (CuO) nanoparticles were synthesised by precipitation method using                    cupric acetate dihydrate [Cu(CH3COO)2.2H2O] as a starting material. The synthesised nanoparticles were characterised by X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). These nanoparticles were dispersed in three different base fluids which were 10% aqueous solutions of ethylene glycol (EG), propylene glycol (PG) and hexylene glycol (HG). Ultrasonic velocity (U), density (ρ) and viscosity (η) of these nanofluids were measured at different concentrations of CuO nanoparticles as a function of temperatures (T = 303.15K, 308.15K and 313.15 K). Using these values various acoustical parameters such as adiabatic compressibility, intermolecular free length, relaxation time, acoustic impedence and attenuation coefficient were evaluated

SWINE FLU- THE CHANGING SCENARIO AND PREPAREDNESS WITH FORMULATION OF WIN FLU AIR FRESHENER GEL

Swine flu is an emerging viral infection that is a present global public health problem. There are many thousand cases of swine flu can be seen around the world in the present day. Due to the nature of a respiratory virus, the transmission of this pathogenic virus is airborne transmission. Hence, the rapid spreading and difficulty in control of this infection can be expected. Ayurved believes in Nidan parivarjan and recommends the strengthening of the immunity to prevent disease like swine flu from its attack. There are no any medicines or vaccination are available now a days for prevent from swine flu. Mask is an only available option from avoiding the virus, but sometimes it fails to stop the infection and peoples are unable to wearing mask for all time. So there is a need to develop such a thing which we can carry easily with us and protecting from the infection. Many environment purification techniques (like Homa, Yagya, Dhoopana) have been mentioned in our classical texts. Several scientific studies have validated the clinical efficacy of air freshener against the viral stains. Freshener is a household product that can release the chemicals they contain into the air and inhaled by consumers. The purpose of this research is to determine the ability of herbal essential oil to be formulated as a WIN FLU- air freshener gel with fragrance of citrus oil and binder of peppermint oil. Gel formulation in the study was made from a mixture of herbal essential oil (carom seed, Eucalyptus, Basil, Ginger, Clove), sodium benzoate, peppermint and citrus essential oil in distilled water with a variety of different concentrations of herbal essential oil at 1%, 2% and 3%, then performed an evaluation form hedonic test gel with 30 panelists, evaporation of a liquid test during 4 weeks of storage. The results of this study indicate that the best gel formula is the formula A3 with an herbal essential oil concentration of 3%. Results per cent of total evaporation of liquid air freshener gel formula are respectively 59.12%, 42.32%, 21.22%

Performance analysis of InAlN/GaN HEMT and optimization for high frequency applications

An InAlN/GaN HEMT device was studied using extensive temperature dependent DC IV measurements and CV measurements. Barrier traps in the InAlN layer were characterized using transient analysis. Forward gate current was modelled using analytical equations. RF performance of the device was also studied and device parameters were extracted following small signal equivalent circuit model. Extensive simulations in Silvaco TCAD were also carried out by varying stem height, gate length and incorporating back barrier to optimize the suitability of this device in Ku-band by reducing the detrimental Short Channel Effects (SCEs). In this paper a novel structure i.e., a short length T gate with recess, on thin GaN buffer to achieve high cut-off frequency (f$_T$) and high maximum oscillating frequency (f$_{max}$) apt for Ku-band applications is also proposed

No difference in sports participation and patient-reported functional outcomes between total knee arthroplasty and unicompartmental knee arthroplasty at minimum 2-year follow-up in a matched control study

Purpose The purpose of this study was to compare (1) sports participation and type of sports activity between TKA and UKA patients; (2) functional outcome and activity level between TKA and UKA; and (3) survivorship of the prosthesis in both the groups. Methods Prospectively collected data were obtained from an arthroplasty database to identify patients who underwent primary TKA and UKA. Both the cohorts of TKA and UKA were matched, controlling for age, sex, BMI and preoperative patient-reported outcomes, which include Oxford Knee Score (OKS), Tegner activity level, and visual analog scale (VAS) for pain score. After matching the two groups, 287 TKA and 69 UKA cases were available to be included in the study. Patients were evaluated pre- and postoperatively at 2 years for sports participation and sports preference, patient-reported outcomes, activity levels, and improvement in knee pain. Results The mean age of the TKA and UKA groups were 75.7 +/- 8.1 and 74.2 +/- 8.8, respectively. There was no significant difference between the two groups concerning the demographic variables. Significant improvement was noted in the weekly sports participation at the final follow-up compared to preoperative sports participation in both the TKA and UKA groups (p 0.05). OKS, Tegner activity level and VAS for pain demonstrated a significant improvement from preoperative to 2 years postoperatively (p 0.05). No case of revision surgery was found at a 2-year follow-up in both groups. Conclusion Traditionally, in isolated medial compartment osteoarthritis, UKA has been considered to be the procedure with better functional outcomes, but the current study demonstrates that when confounding factors are controlled, both TKA and UKA are effective, and offer similar functional outcomes and result in similar improvement in sports participation. These findings will be helpful to counsel the patients to choose the best suitable operative procedure between UKA and TKA

Primary Versus Revision ACL Reconstruction Using Quadriceps Autograft: A Matched-Control Cohort Study

Background: The incidence of anterior cruciate ligament (ACL) reconstruction is increasing, and quadriceps tendon (QT) autograft is gaining popularity for both primary and revision ACL reconstruction. Purpose: To evaluate the differences in the patient-reported functional outcomes, concomitant injuries, and graft failure in primary versus revision ACL surgery using QT autograft. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 376 patients with primary ACL reconstruction and 138 patients with revision ACL reconstruction were retrospectively retrieved from a prospectively collected ACL registry. A minimally invasive technique was used for QT autograft harvesting. The surgical procedure and rehabilitation protocol were identical in both groups. To maintain a homogeneous cohort for the study, the groups were matched by age, sex, and preinjury outcome scores (Lysholm knee score, Tegner activity level, and visual analog scale [VAS] for pain). Initial baseline assessments of outcome scores were compared with scores collected at the 2-year postoperative mark. Results: The mean age of the primary group and revision group was 32.9 +/- 10.2 years (range, 18-55 years) and 32.3 +/- 9.9 years (range, 19-55 years) respectively. Significant preinjury to postoperative improvements were noted in Lysholm (88.2 +/- 16.4 vs 83.5 +/- 15.0; P = .007) and VAS pain (0.9 +/- 1.3 vs 1.5 +/- 1.6; P = .001) scores after primary ACL reconstruction compared with revision reconstruction. However, no significant difference was found in Tegner activity level (6.7 +/- 1.8 vs 5.9 +/- 1.8; P > .430). Primary ACL injury was associated with significantly higher concomitant medial collateral ligament injuries (P = .019), while the revision group was associated with significantly higher concomitant cartilage (P = .001) and meniscal (P = .003) injuries. A significantly higher graft failure rate was noted in the revision group compared with the primary ACL reconstruction group (13.0% vs 5.6%; P = .005). Conclusion: Both primary and revision ACL reconstruction with QT autograft had acceptable functional outcomes. The primary group had better outcomes than the revision group, possibly due to the lower prevalence of meniscal and cartilage injuries in the primary group compared with the revision group. The revision group was associated with higher graft failure than the primary group. QT autograft is a viable graft choice for both primary and revision ACL reconstruction

Predictability of STOP-Bang Questionnaire and Epworth Sleepiness Scale in Identifying Obstructive Sleep Apnoea against Polysomnography: A Cross-sectional Study

Introduction: Rising morbidty resulting from Obstructive Sleep Apnoea (OSA) is an emerging public health concern. The estimated prevalence of OSA in India has been investigated. STOP-Bang and Epworth Sleepiness Scale (ESS) have proven beneficial in identifying sleep breathing disorder. Validity of these questionnaire has been verified against polysomnography in many studies. Aim: To assess the predictive ability of STOP-Bang questionnaire and ESS in identifying OSA and comparing their efficacy with polysomnography. Materials and Methods: The cross-sectional study was conducted in the Department of Respiratory Medicine, Government Medical College, Kota, Rajasthan, India, from January 2020 to June 2021, among 100 patients with symptoms of OSA. The STOP-Bang questionnaires were administered to the patients, and scoring was done, followed by overnight attended polysomnography. The normality of data was tested by Shapiro Wilk’s test. The values obtained were statistically analysed and to compare the parameters between groups and with in groups for normal data parametric test One-way Analysis of Variance (ANOVA) followed by Tukey’s HSD test, for intragroup Paired t-test. Results: Mean age of the study population was 49.46±6.523 years, 79 were males and 21 females. Total, 79% of the subjects were males, and 21% of the study subjects were females. Among the 100, 65% had OSA as per polysomnography. STOP-Bang questionnaire had a higher sensitivity as compared to ESS in predicting OSA (75.38% for STOP-Bang and 72.31% for ESS). Conversely, the specificity of ESS (82.8%) was found to be greater than STOP-Bang (45.71%). Similar results were obtained for positive predictive value, in which ESS scored 88.6% while STOP-Bang scored 50%. For negative predictive values, ESS again scored higher (65%) than STOP-Bang (61.7%). Similarly, the Likelihood Ratio for a positive result (LR+) of ESS was greater than STOP-Bang (4.2 and 1.3 respectively). The STOP-Bang questionnaire, however, had higher Likelihood Ratio for a negative test (LR-) as compared to ESS (0.5 and 0.3 respectively). Conclusion: Polysomnography is the gold standard to diagnose OSA. For screening OSA, patients with symptoms of sleep disordered breathing, this study found that STOP-Bang questionnaire is better in identifying OSA as compared to ESS

Population infection estimation from wastewater surveillance for SARS-CoV-2 in Nagpur, India during the second pandemic wave

Wastewater-based epidemiology (WBE) has emerged as an effective environmental surveillance tool for predicting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease outbreaks in high-income countries (HICs) with centralized sewage infrastructure. However, few studies have applied WBE alongside epidemic disease modelling to estimate the prevalence of SARS-CoV-2 in low-resource settings. This study aimed to explore the feasibility of collecting untreated wastewater samples from rural and urban catchment areas of Nagpur district, to detect and quantify SARS-CoV-2 using real-time qPCR, to compare geographic differences in viral loads, and to integrate the wastewater data into a modified Susceptible-Exposed-Infectious-Confirmed Positives-Recovered (SEIPR) model. Of the 983 wastewater samples analyzed for SARS-CoV-2 RNA, we detected significantly higher sample positivity rates, 43.7% (95% confidence interval (CI) 40.1, 47.4) and 30.4% (95% CI 24.66, 36.66), and higher viral loads for the urban compared with rural samples, respectively. The Basic reproductive number, R0, positively correlated with population density and negatively correlated with humidity, a proxy for rainfall and dilution of waste in the sewers. The SEIPR model estimated the rate of unreported coronavirus disease 2019 (COVID-19) cases at the start of the wave as 13.97 [95% CI (10.17, 17.0)] times that of confirmed cases, representing a material difference in cases and healthcare resource burden. Wastewater surveillance might prove to be a more reliable way to prepare for surges in COVID-19 cases during future waves for authorities
