An Enhanced AES-ECC model with Key Dependent Dynamic S-Box for the Security of Mobile Applications using Cloud Computing
Authors: Nagaraj M Lutimath Maria Navin J R , 
Published: April 2024

The spectacular growth of computational clouds has drawn attention and enabled intensive computing on client devices with constrained resources. Smart phones mostly use the data centre demand service model to provide data to computationally intensive applications. It is challenging to outsource sensitive and private information to distant data centres due to growing concerns about data privacy and security. Therefore, conventional security algorithms have to be upgraded to address the brand-new security concerns that have emerged in the cloud environment. The Advanced Encryption Standard (AES) algorithm encrypts and decrypts messages using the four steps, namely Sub-Bytes, Shift-Rows, Mix-Columns, and Add Round Key. It has been changed so that the Sub-byte transformation depends on the round key. Making the S box round key dependent is intended to make it such that even a little change in the key will have a big impact on the cipher text. The avalanche effect and execution time of the standard and modified AES algorithms are implemented and assessed. In order to suggest a safe and efficient solution, the study also aims to modify the shift rows and the mix column phases of AES. Using cryptographic techniques such as elliptic curve cryptography (ECC), several protocols and algorithms have been developed to guarantee the security and integrity of the data. The proposed solution combines the enhanced and updated The Advanced Encryption Standard (AES) technology with the ECC to guarantee data secrecy. The avalanche effect approach is used in this study to explore and analyze the strength and quality of the new s-box. The results demonstrated that each encryption operation generates a unique cipher text. A strong avalanche effect was also achieved with the redesigned dynamic s-box using irreducible polynomials, surpassing the strict avalanche criterion (SAC). The results show that the proposed method ECC-EAESKDS Elliptic Curve Cryptography-Enhanced AES with Key Dependent S box is efficient and yields better results than the alternatives. According to the suggested security architecture, cloud users may control data protection and integrity in a secure manner.
Advanced Heart Disease Prediction: Deep Learning-Enhanced Convolutional Neural Network in the Internet of Medical Things Environment
Authors: Aarti Karandikar,  
Published: April 2024

Using the large dataset from the UCI Machine Learning Repository, this study presents a state-of-the-art Hybrid Convolutional Neural Network (HCNN) for predicting heart disease. The HCNN design has convolutional layers, leftover blocks, and attention methods. These help pull more features from cardiovascular health data, even when the patterns are very complex. Utilizing these deep learning parts, the HCNN shows better prediction skills, getting higher accuracy, strong classification (AUC), and a fair F1 Score. Because the model can change to find complicated connections in the information, it could be used to make medical diagnosis better. The HCNN is unique because it can instantly learn hierarchical structures from raw data. This lets it find hidden features that are important for accurately predicting heart disease. The convolutional layers help the model find local patterns, and the residue blocks stop problems with disappearing gradients, which makes training for deep designs more efficient. Attention processes make the network even more focused on important traits, which adds to its amazing ability to tell them apart. This work opens the door for researchers, doctors, and data scientists to use deep learning, and especially HCNN, to improve cardiovascular health analytics. This study takes a big step toward more accurate and efficient heart disease prognosis by giving a complete overview of the model's architecture and performance metrics. This opens the door for more research and use of advanced neural networks in the field of predictive medical diagnostics.

Novel Potassium Binders for CKD Patients with Hyperkalemia
Authors: Dahlan Randah , Alkatheeri Ali 
Published: April 2024

Hyperkalemia is defined as a serum or plasma potassium level that is greater than 5.0 or 5.5 mmol/L, and this variation is because the definition of the upper limit of normal level used in research and guidelines is varied. Hyperkalemia is a potentially life-threatening condition that may lead to muscle paralysis, cardiac arrhythmia, and death. It is a common clinical problem seen in patients with chronic kidney disease (CKD), and this is particularly true with the progressive and advanced deterioration of the glomerular filtration rate (GFR). The management of such patients could be a challenge to nephrologists, especially since the therapeutic interventions that are used to slow the progression of CKD may themselves lead to or worsen hyperkalemia. This chapter will discuss the issue of hyperkalemia in CKD patients and will focus on the role of novel potassium binders in the management of such patients.

Context.—
Rapid advancements in the understanding and manipulation of tumor-immune interactions have led to the approval of immune therapies for patients with non–small cell lung cancer. Certain immune checkpoint inhibitor therapies require the use of companion diagnostics, but methodologic variability has led to uncertainty around test selection and implementation in practice.

Objective.—
To develop evidence-based guideline recommendations for the testing of immunotherapy/immunomodulatory biomarkers, including programmed death ligand-1 (PD-L1) and tumor mutation burden (TMB), in patients with lung cancer.

Design.—
The College of American Pathologists convened a panel of experts in non–small cell lung cancer and biomarker testing to develop evidence-based recommendations in accordance with the standards for trustworthy clinical practice guidelines established by the National Academy of Medicine. A systematic literature review was conducted to address 8 key questions. Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach, recommendations were created from the available evidence, certainty of that evidence, and key judgments as defined in the GRADE Evidence to Decision framework.

Results.—
Six recommendation statements were developed.

Conclusions.—
This guideline summarizes the current understanding and hurdles associated with the use of PD-L1 expression and TMB testing for immune checkpoint inhibitor therapy selection in patients with advanced non–small cell lung cancer and presents evidence-based recommendations for PD-L1 and TMB testing in the clinical setting.
As objetivações do Mercado na Educação Física do Novo Ensino Médio
Authors: Ramos Fabricio , Frizzo Giovanni 
Published: April 2024

Neste trabalho, procuramos investigar os impactos da mais recente Reforma Curricular na educação brasileira, promovidos pela Lei 13.415/17 e pela nova Base Nacional Comum Curricular (BNCC), para o componente curricular Educação Física. Para tanto, analisamos os documentos oficiais (leis, decretos e Medidas Provisórias), bem como a literatura já produzida sobre a matéria, disponibilizadas em artigos, revistas e livros. Observamos que as diversas reformas educacionais promovidas pelos órgãos oficiais são resultado de pressões externas, que procuram adaptar constantemente a educação pública às necessidades dos processos de reestruturação capitalista, representados, neste caso, pelas leis de mercado. Observamos também que as mudanças impostas pela mais nova reforma educacional estão em perfeita sintonia com a reestruturação produtiva vigente, colocando um papel secundário para a Educação Física brasileira, pois essa perde o protagonismo na formação objetivada pelo capital. Entendemos também que, nas mediações para legitimação do capital, a Educação assume um papel central nesse processo, sendo necessário o estabelecimento de novos objetivos e de novas finalidades para os processos de formação humana.

Published: April 2024

To evaluate the green manure crops those can promote soil properties and the ability of nitrogen (N) mineralization in paddy soil, a pot experiment was conducted at the Department of Agronomy, Yezin Agricultural University, Naypyidaw, Myanmar from April to August 2022. The experimental design was a randomized complete block design with three replications. Ten green manure crops were sown as treatments: soybean (Glycine max (L.) Merr), green gram (Vigna radiata L. Wildzek.), black gram (Vigna mungo L. Hepper.), cowpea (Vigna catjang), cowpea white (Vigna unguiculata (L.) Walp.), lab lab bean (Lablab purpureus (L.) Sweet.), mayflower bean (Phaseolus vulgaris L.), rice bean (Vigna umbellata), sunn hemp (Crotalaria juncea L.), and dhaincha (Sesbania bispinosa (Jacq.)). At the flowering stage, various green manures were incorporated into the soil, and their growth characters were measured along with the mineralizable N, total N, phosphorus (P2O5), and potassium (K2O) contents of the soil. The results indicated that rice bean, sunn hemp, and dhaincha had higher shoot and root length, shoot and root fresh weight, and dry weight compared to other varieties. In addition, they contain a higher percentage of total N content and total P2O5, and consequently, its C:N ratio was lower. After incorporating green manures into the soil, the mineralizable N increased gradually from 0 weeks to 10 weeks and then, the nutrient values decreased. Among green manures, sunn hemp, dhaincha, and rice bean were found to have higher mineralizable N (%) and applicable mineralized N than others. In conclusion, the incorporation of green manures into the soil improves the N, P2O5, and K2O contents of the soil, along with the mineralizable N content. Among green manure crops, dhaincha, rice bean, and sunn hemp were superior to other varieties due to higher biomass yield, mineralizable N (%), and chemical compositions, especially total N content.

Background: The oral intake of alcohol has become a widespread concern due to its high risk to body health. Therefore, our purpose in this study was to reveal the antioxidant efficacies of natural Costus's afer stem juice extract on hepatotoxicity induced by ethanol in adult female wistar rats.
Methods: We examined the impacts of liver toxicity, were the experimental animals were given 1ml of 10% ethanol daily for 21 days, thereafter, C. afer was administered to evaluate its ameliorative effect in the female albino wistar rats orally treated with C. afer juice extract (200 and 400 mg/kg) for 7days. The rats were divided into four (4) groups; Group A served as the control group, which was given rat chow and water only. Groups B, C and D were given 1ml of 10% ethanol. Afterwards, groups C and D were treated with 200 and 400 mg/kg using 1ml and 2ml of the juice extract of C. afer, respectively. A liver function test and histological analysis were carried out.
Results: The results showed that treatment with C. afer after the oral consumption of ethanol caused elevation in serum liver function parameters (alanine transferases, aspartate transaminase, and alkaline phosphate), which is significant compared to the control group. There was also a slight restoration in histopathological changes in the liver, as revealed by decreased areas of inflammation.
Conclusion: The therapeutic efficiency of C. afer juice extract could be due to traces of anti-inflammatory properties and the ROS-scavenging agent. Our findings prove that the elevation of liver function markers by C. afer enables hepatic tissue to suppress inflammatory and oxidative mechanisms, resulting in enhanced liver structure and function. Therefore, C. afer extract is a protective and therapeutic supplement against toxic agents.
Successful Intestinal Blood Flow Evaluation Using Indocyanine Green Fluorescent Imaging in a Case of Small Intestine Strangulation
Authors: Matsune Yusuke , Aoki Takeshi , Tashiro Yoshihiko 
Published: April 2024

Introduction
The assessment of intestinal blood flow using indocyanine green (ICG) fluorescence imaging is useful in ischemic bowel disease because it renders blood flow visible. Strangulated small intestine is a common postoperative complication requiring massive bowel resection, which can cause short bowel obstruction (SBO), a malabsorptive condition. Here, we report a successful case of preserving an ischemic intestinal segment while avoiding SBO based on the gap between the macroscopic findings and the ICG fluorescence imaging assessment.

Case presentation
A 46-year-old Japanese female patient who underwent an abdominal total hysterectomy and bilateral salpingo-oophorectomy with para-aortic lymphadenectomy due to small round cells of the left ovary received a diagnosis of strangulated small intestine 1 month postoperatively. Macroscopic examination during the laparotomy revealed a strangulated small intestine with severe edema and dark red discoloration. However, this part of the bowel was preserved during surgery because the two-time administration of ICG solution revealed adequate perfusion.

Conclusion
This report reveals the effectiveness of ICG fluorescence imaging in intraoperative intestinal perfusion and its role in avoiding unnecessary massive resections. Combining these modalities may be effective for intraoperative bowel assessment; however, more accurate criteria and algorithms for evaluating blood flow and bowel perfusion should be established.
Wedge test of carbon‐nanotube‐reinforced epoxy adhesive joints
Authors: Yu Suzhu , Tong Min Nah , Critchlow Gary 
Published: December 2008

AbstractEpoxy adhesives reinforced with carbon nanotubes (CNTs) were developed. The distribution of the CNTs in the epoxy matrix was observed with transmission electron microscopy. Joints were formed by unclad 2024‐T3 aluminum adherents bonded with the CNT‐filled epoxy adhesives. The durability of the joints was studied with a wedge test under water at 60°C. The addition of CNTs to the epoxy greatly improved the adhesive joint durability. The initial crack length of the joint with 1 wt % CNTs, which was obtained before the wedge specimen was put into water, was only about 7% of that with neat epoxy. After immersion of the specimens in 60°C water, the joint with neat epoxy failed after 3 h, but all of the joints adhered with different fractions of CNTs were still bound together after the experimental time of 90 h. The significant enhancement by CNTs of the adhesive joint durability was mainly attributed to the high mechanical properties of the CNTs and their ability to resist water. Nevertheless, the experimental results also reveal that the durability of the joints showed an optimum value at approximately 1 wt % CNTs, beyond which a decrease in the property was observed. In addition, the failure mechanism of the joints was also investigated in terms of interfacial failure and cohesive failure. Cohesive dominated failure was found for the joint bonded with 1 wt % CNT‐filled epoxy. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
Comparative study on the technological properties of latex and natural rubber from Hancornia speciosa Gomes and Hevea brasiliensis

Published: December 2008

AbstractThis work reports a systematic comparative study of the technological properties of natural lattices and rubbers extracted from Hancornia speciosa Gomes and Hevea brasiliensis [(Willd. ex Adr. de Juss.) Muell.‐Arg.] (clone RRIM 600) trees from 11 collections in Brazil throughout 2004. Natural rubber latex particle sizes and distributions were quite similar with an average diameter around 1 μm. Molecular weight, Wallace plasticity, and Mooney viscosity values were approximately the same for both rubbers. Fourier transform infrared spectroscopy peaks characteristic of natural rubber were observed for both Hancornia and Hevea. The measured differences in technological properties included lower values for Hancornia dry rubber content, % ash, % nitrogen, and plasticity retention index but higher value for acetone extract. Interestingly, nitrogen and protein content were much lower in Hancornia, suggesting that it may have important applications in nonallergic rubber uses. This represents the first report of lacticifer‐produced low‐protein natural rubber. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2009
Comparisons of weathering performance of two automotive refinish coatings: A case study
Authors: Yari H. , Mohseni M. , Ramezanzadeh B. 
Published: December 2008

AbstractThe aim of this study was to compare the weathering performance of two commonly refinish coatings used in a domestic car manufacturer based on polyurethane (PU) and acid‐catalyzed alkyd‐melamine resins. The replacement of the alkyd‐melamine refinish with the PU system was shown to largely lower the reported fading behavior of the monocoat system. For better comparison between the refinish coatings, an original equipment manufacturers' (OEM) topcoat, cured at production line, was also used. Different characterization methods including DSC, atomic force microscopy, thermo gravimetric analysis, DMTA, and Fourier transform infrared spectroscopy were performed to elucidate the changes observed in the optical, mechanical, and weathering performance of studied coatings. It was found that the main reason for the inferior behavior of the acid‐catalyzed coatings compared with that of the PU and OEM was due to its low crosslinking density. The poor weathering resistance of the former coatings was attributed to its incomplete curing reaction and therefore, to its immatured film formation. © 2008 Wiley Periodicals, Inc.

Multiwalled carbon nanotube nucleated crystallization behavior of biodegradable poly(butylene succinate) nanocomposites
Authors: Pramoda K. P. , Linh N. T. T. , Zhang Chao , Liu Tianxi 
Published: December 2008

AbstractPoly(butylene succinate) (PBS) nanocomposites with multiwalled carbon nanotubes (MWNTs) prepared by melt compounding were studied for the effect of MWNT dispersion on the modulus and crystallization kinetics. The nucleating effect of the addition of 0.1 wt % MWNT to PBS was clearly demonstrated. Differential scanning calorimetry nonisothermal crystallization studies showed a clear decrease in the half‐time of crystallization with increasing MWNT content in PBS/MWNT nanocomposites. It was observed with the Ozawa method that the Ozawa parameter values for the nanocomposites were lower than those for neat PBS, and this indicated that the crystal morphology was different. The storage modulus of the nanocomposites increased about 23% with the addition of only 0.1% MWNT in comparison with neat PBS, whereas the glass‐transition temperature was unaltered. © 2008 Wiley Periodicals, Inc.

Friction and wear properties of polyimide matrix composites reinforced with short basalt fibers
Authors: Zhang Xinrui , Pei Xianqiang , Wang Qihua 
Published: December 2008

AbstractShort basalt fiber (BF) reinforced polyimide (PI) composites were fabricated by means of compression‐molding technique. The friction and wear properties of the resulting composites sliding against GCr15 steel were investigated on a model ring‐on‐block test rig under dry sliding conditions. The morphologies of the worn surfaces and the transfer films that formed on the counterpart steel rings were analyzed by means of scanning electron microscopy. The influence of the short BF content, load, and sliding speed on the tribological behavior of the PI composites was examined. Experimental results revealed that the low incorporation of BFs could improve the tribological behavior of the PI composites remarkably. The friction coefficient and wear rate decreased with increases in the sliding speed and load, respectively. The transfer film that formed on the counterpart surface during the friction process made contributions to reducing the friction coefficient and wear rate of the BF‐reinforced PI composites. © 2008 Wiley Periodicals, Inc.
