Every day,more and more data is being produced by the Internet of Things(IoT)applications.IoT data differ in amount,diversity,veracity,and velocity.Because of latency,various types of data handling in cloud computing are not suitable for many time-sensitive applications.When users move from one site to another,mobility also adds to the latency.By placing computing close to IoT devices with mobility support,fog computing addresses these problems.An efficient Load Balancing Algorithm(LBA)improves user experience and Quality of Service(QoS).Classification of request(Cor)based resource Adaptive LBA is suggested in this research.This technique clusters fog nodes using an efficient k-means clustering algorithm and then uses a Decision Tree approach to categorize the request.The decision-making process for time-sensitive and delay-tolerable requests is facilitated by the classification of requests.LBA does the operation based on these classifications.The MobFogSim simulation program is utilized to assess how well the algorithm with mobility features performs.The outcome demonstrates that the LBA algorithm’s performance enhances the total system performance,which was attained by(90.8%).Using LBA,several metrics may be examined,including response Time(rT),delay(d),Energy Consumption(EC),and latency.Through the on-demand provisioning of necessary resources to IoT users,our suggested LBA assures effective resource usage.

OBJECTIVE: To explore the total phenolic and flavonoid content, enzymatic, non-enzymatic antioxidant properties, anti-inflammation and anticancer activities of hexane, ethyl acetate and methanol extracts of Floscopa scandens(F. scandens).METHODS: Non-enzymatic antioxidant activity was examined by 2, 2-diphenyl-1-picrylhydrazyl assay, nitric oxide scavenging assay, hydroxyl radical scavenging assay, reducing power assay, hydrogen peroxide scavenging assay, superoxide scavenging assay and metal chelating assay. Enzymatic antioxidant ability was screened for the antioxidant enzymes such as ascorbate oxidase, peroxidase, catalase and polyphenol oxidase. The anti-inflammatory property was proved with the inhibition of protein denaturation and protease inhibitory assays. In vitro anticancer activity was assessed by cell viability assay.rESULTS: Methanol extract contained high amount of phenols(198.41 mg catechol equivalent/gram extract) and flavonoids(101.70 mg quercetin equivalent/gram extract) showed higher activity than hexane and ethyl acetate extracts in all experiments. Fresh plant showed considerable enzymatic antioxidant activity.CONCLUSION: The results revealed that the methanol extracts of F. scandens could be used as a potential source of antioxidant, anti-inflammatory and anticancer bioactive compounds.

This review aims to identify in vivo studies investigating the potential of plant substances and their natural molecules in managing inflammatory bowel disease(IBD).Specifically,the objective is to examine the impact of these substances on interleukins and other key inflammatory signaling mark.rs.relevant articles published up to December 2022 were identified through a search of the PubMed,Scopus,Web of Science,and Embase databases.The search used keywords including“inflammatory bowel disease”,“medicinal plants”,“natural molecules”,“anti-inflammatory”,and“ulcerative colitis”,and identified 1,878 potentially relevant articles,of which 89 were included in this review after completion of the selection process.This study provides preclinical data on natural products(NPs)that can potentially treat IBD,including ulcerative colitis.The main actions of these NPs relate to their effects on nuclear factor kappa B(NF-κβ),the Janus kinase(JAk)/signal transducer and activator of transcription(STAT)signaling pathway,the regulation of T helper 17/regulatory T cells balance,and oxidative stress.The ability of these NPs to inhibit intestinal inflammation appears to be dependent on lowering levels of the pro-inflammatory cytokines tumor necrosis factor-alpha(TNF-α),interleukin(IL)-1β,and IL-17,via the Jun N-terminal kinase(JNk)1,NF-κβ-p65,and STAT3 pathways.In addition,NPs were shown to reduce oxidative stress and the severity of ulcerative colitis,as well as increase the activity of antioxidant enzymes.These actions suggest that NPs represent a promising treatment for IBD,and potentially have greater efficacy and safety than current treatments.

Fault tolerance(FT)schemes are intended to work on a minimized and static amount of physical resources.When a host failure occurs,the conventional FT frequently proceeds with the execution on the accessible working hosts.This methodology saves the execution state and applications to complete without disruption.However,the dynamicity of open cloud assets is not seen when taking scheduling choices.Existing optimization techniques are intended in dealing with resource scheduling.This method will be utilized for distributing the approaching tasks to the VMs.However,the dynamic scheduling for this procedure doesn’t accomplish the objective of adaptation of internal failure.The scheme prefers jobs in the activity list with the most elevated execution time on resources that can execute in a shorter timeframe,but it suffers with higher makespan;poor resource usage and unbalance load concerns.To overcome the above mentioned issue,Fault Aware Dynamic resource Manager(FAdrM)is proposed that enhances the mechanism to Multi-stage resilience Manager at an application-level FT arrangement.Proposed FAdrM method gives FT a Multi-stage resilience Manager(MrM)in the client and application layers,and simultaneously decreases the over-head and degradations.It additionally provides safety to the application execution considering the clients,application and framework necessities.Based on experimental evaluations,Proposed Fault Aware Dynamic resource Manager(FAdrM)method 157.5 MakeSpan(MS)time,0.38 Fault rate(Fr),0.25 Failure Delay(FD)and improves 5.5 Performance Improvement ratio(PIr)for 25,50,75 and 100 tasks and 475 MakeSpan(MS)time,0.40 Fault rate(Fr),1.30 Failure Delay(FD)and improves 6.75 improves Performance Improvement ratio(PEr)for 100,200,300 and 500 Tasks compare than existing methodologies.

Microstructure and mechanical properties of an extruded Mg-2Dy-0.5Zn （at.%） alloy during isothermal ageing at 180℃ were investigated. Microstructure of the as-extruded alloy is mainly composed of α-Mg phase, 14H long period stacking order （LPSO） phase and small amounts of （Mg, Zn）=Dy particle phases. During ageing, the 14H LPSO phase forms and develops and its volume fraction increases with increasing ageing time. Tensile test showed that the peak-aged alloy exhibits similar yield and ultimate tensile strengths and elongation to failure at room temperature, 100℃ and 200℃, but excellent elevated temperature strengths at 300℃ as compared to the as-extruded and over-aged alloys. The analysis showed that the excellent elevated temperature strengths of the peak-aged alloy are attributed to the LPSO phase strengthening and the grain refinement strengthening, and the role of the LPSO strengthening is related to not only its amount, but also its morphology.

Organic nonlinear optical material of 4-bromo-4’-methyl benzylidene aniline (BMBA) was synthesized and single crystal of BMBA was grown by solvent evaporation method at room temperature using ethanol as solvent. The crystalline nature of the grown crystals was confirmed using powder X-ray diffraction studies. The crystals were also characterized by single crystal X-ray diffraction method and their lattice parameters were determined. Thermal properties of BMBA were evaluated with thermogravimetric, differential thermal and differential scanning calorimetric analyses. Fourier transform infrared and FT-raman spectral studies were carried out on the BMBA material to confirm the synthesized compound. 1H and 13C-nuclear magnetic resonance spectral studies were recorded to elucidate the structure of the grown crystals. Fluorescence spectrum recorded shows a peak at 485 nm. UV-Vis-NIr spectral analysis shows transmittance of ~92% in the visible region. The mechanical stability was analyzed by Vick.rs microhardness tester and the work hardening coefficient of the grown crystal was calculated. Second harmonic generation efficiency of the grown crystal measured by k.rtz powder technique is ~1.8 times that of potassium dihydrogen orthophosphate.
