Static Aeroelasticity Using High Fidelity Aerodynamics in a Staggered Coupled and ROM Scheme

Current technology in evaluating the aeroelastic behavior of aerospace structures is based on the staggered coupling between structural and low fidelity linearized aerodynamic solvers, which has inherent limitations, although tried and trusted outside the transonic region. These limitations arise from the assumptions in the formulation of linearized aerodynamics and the lower fidelity in the description of the flowfield surrounding the structure. The validity of low fidelity aerodynamics also degrades fast with the deviation from a typical aerodynamic shape due to the inclusion of various control devices, gaps, or discontinuities. As innovative wings tend to become more flexible and also include a variety of morphing devices, it is expected that using low fidelity linearized aerodynamics in aeroelastic analysis will tend to induce higher levels of uncertainty in the results. An obvious solution to these issues is to use high fidelity aerodynamics. However, using high fidelity aerodynamics incurs a very high computational cost. Various formulations of reduced order models have shown promising results in reducing the computational cost. In the present work, the static aeroelastic behavior of three characteristic aeroelastic problems is obtained using both a full three-dimensional staggered coupled scheme and a time domain Volterra series based reduced order model (ROM). The reduced order model’s ability to remain valid for a wide range of dynamic pressures around a specific Mach number (and Reynolds number regime if viscous flow is considered) and the capability to modify structural parameters such as damping ratios and natural frequencies are highlighted.
Bariatric Surgery: Preoperative Assessment

Obesity is associated with increased morbidity and mortality and impaired quality of life. Weight losse is associated with improvement or even cure of cardiovascular risk factors with cardiometabolic benefit. nonsurgical measures for weight loss is rarely successful in the long term. Bariatric surgery has achieved clear success in reversing the abnormal metabolic profile associated with obesity. Pre surgical evaluation is important to rule out any medical or psychological problems that increased the surgical mortality or adversely affect the outcome.
Extractive Desulfurization Using Fe-Containing Ionic Liquids

FeIII-containing ionic liquids (ILs), prepared from the reaction of anhydrous FeCl3 and imidazolium chloride ([imidazolium]Cl), were used as effective extractants for the desulfurization of a model oil containing dibenzothiophene (DBT). The amount of DBT extracted increased with an increasing molar ratio of FeCl3/[imidazolium]Cl. The ability of the ILs to extract DBT seems to be attributed to the combined effects of Lewis acidity and fluidity of ILs.

Encoding different types of topics and foci in German Sign Language. A cartographic approach to sign language syntax

This paper presents a comprehensive overview of the encoding strategies of different types of topics and foci in (the southern variant of) German Sign Language (Deutsche Gebardensprache, DGS). The discussion will be guided by two main hypotheses: (i) the existence of a strict, universal ordering of topic and focus projections in the tradition of Rizzi (1997) and (ii) the Bodily Mapping Hypothesis (Bross & Hole 2017; Bross 2020), i. e. , the hypothesis that scope is expressed in a systematic way in sign languages: the higher an operator is located in the syntactic tree, the higher the articulator expressing it will be. As this study is concerned with very high CP categories, the Bodily Mapping Hypothesis predicts that the categories under discussion will be marked with the highest possible articulators, i.e., the eyebrows. Concerning topics, base-generated frame setters (epistemic, locative, and temporal frames) and moved aboutness topics will be discussed as well as structures resembling pseudo-clefts. Concerning focus, contrastive and mirative focus as well as regular cleft sentences will be examined.
A study of the failure mechanism of a titanium nitride diffusion barrier

TiN has been popularly used as a diffusion barrier between Al and Si to prevent “spiking. ” It has, however, been reported that spiking still occurs through TiN at temperatures higher than 500 °C. In this study, we investigated the mechanism of spiking through TiN using high resolution transmission electron microscopy and electron dispersive spectroscopy (EDS). We found TiN to be saturated with Al upon annealing at 550 °C. Si also diffuses through TiN and dissolves into Al. Spikes form upon 550 °C annealing at the Si substrate. EDS analysis revealed the phase of the spikes to be Al3Ti containing a considerable amount of Si. These results indicate that spiking through TiN is due to the formation and growth of Al3Ti after the Al saturation at the bottom of TiN. We discuss these results based on the Al–Ti–Si and Al–Ti–N ternary phase diagrams.

Environmental Occurrence and Ecological Risk
of Bisphenol A in Erhai Lake Basin Away
From Industrial Regions in China

The environmental distribution and migration of bisphenol A (BPA) has attracted attention due to its widespread use. The Erhai Lake Basin is dominated by agricultural production and tourism, and almost no industry. In this research, BPA pollution in the non-industrial region was investigated. BPA was found in all samples of inflow rivers, with concentrations ranging 2.80 ng/L~61.85 ng/L. The measured 15 rivers that account for 78.7% of the total inflow volume were inputting BPA concentration of 20.69 ng/L into Erhai Lake with an annual load of 8.54 kg/year. The measured BPA removal efficiency of sewage treatment plants ranged 49.8%~92.8%. Oxidation Ditch and A2O-MBR treatment process achieved the better BPA removal efficiency. The amount of BPA discharged directly to Erhai Lake from the effluent of the sewage plants each year was 1.63 kg. Based on the above research, a multimedia model of QWASI was established, and water concentration calculated was 0.203ng/L. A PNEC value considering more sensitive receptors was applied to this study, and it was indicated that there was a certain ecological risk in the water of the Boluo River estuary, while other rivers and lake were relatively safe. It was revealed that the ecological risk of BPA was relatively low in the Erhai Lake.
Performance Evaluation of a Proposed Machine Learning Model for Chronic Disease Datasets Using an Integrated Attribute Evaluator and an Improved Decision Tree Classifier

There is a consistent rise in chronic diseases worldwide. These diseases decrease immunity and the quality of daily life. The treatment of these disorders is a challenging task for medical professionals. Dimensionality reduction techniques make it possible to handle big data samples, providing decision support in relation to chronic diseases. These datasets contain a series of symptoms that are used in disease prediction. The presence of redundant and irrelevant symptoms in the datasets should be identified and removed using feature selection techniques to improve classification accuracy. Therefore, the main contribution of this paper is a comparative analysis of the impact of wrapper and filter selection methods on classification performance. The filter methods that have been considered include the Correlation Feature Selection (CFS) method, the Information Gain (IG) method and the Chi-Square (CS) method. The wrapper methods that have been considered include the Best First Search (BFS) method, the Linear Forward Selection (LFS) method and the Greedy Step Wise Search (GSS) method. A Decision Tree algorithm has been used as a classifier for this analysis and is implemented through the WEKA tool. An attribute significance analysis has been performed on the diabetes, breast cancer and heart disease datasets used in the study. It was observed that the CFS method outperformed other filter methods concerning the accuracy rate and execution time. The accuracy rate using the CFS method on the datasets for heart disease, diabetes, breast cancer was 93.8%, 89.5% and 96.8% respectively. Moreover, latency delays of 1.08 s, 1.02 s and 1.01 s were noted using the same method for the respective datasets. Among wrapper methods, BFS’ performance was impressive in comparison to other methods. Maximum accuracy of 94.7%, 95.8% and 96.8% were achieved on the datasets for heart disease, diabetes and breast cancer respectively. Latency delays of 1.42 s, 1.44 s and 132 s were recorded using the same method for the respective datasets. On the basis of the obtained result, a new hybrid Attribute Evaluator method has been proposed which effectively integrates enhanced K-Means clustering with the CFS filter method and the BFS wrapper method. Furthermore, the hybrid method was evaluated with an improved decision tree classifier. The improved decision tree classifier combined clustering with classification. It was validated on 14 different chronic disease datasets and its performance was recorded. A very optimal and consistent classification performance was observed. The mean values for accuracy, specificity, sensitivity and f-score metrics were 96.7%, 96.5%, 95.6% and 96.2% respectively.
ATOM-MOLECULE VAN DER WAALS COMPLEXES CONTAINING OPEN-SHELL ATOMS. I: GENERAL THEORY AND BENDING LEVELS

The theory needed to carry out calculations on atom–molecule van der Waals complexes containing open‐shell atoms is developed. The discussion concentrates on complexes containing atoms in P states. Several possible expansions of the total wave function are described, and the matrix elements needed to construct the Hamiltonian matrix are set out. Several different angular momentum coupling cases may arise, analogous to Hund’s coupling cases in diatomic molecules. The bending energy levels of Ca–HCl, B–H2, F–H2, Cl–Cl2, and F–N2 are calculated, using simple models of the interaction potentials.
Dispersion of Silicate in Tricalcium Phosphate Elucidated by Solid-State NMR

The dispersion of silicate in tricalcium phosphate, a resorbable bioceramics for bone replacement, has been investigated by various solid-state nuclear magnetic resonance (NMR) methods. In samples prepared with 5 and 10 mol % of both 29SiO2 and ZnO, three types of silicate have been detected: (i) SiO44− (Q0 sites) with long longitudinal (T1,Si) relaxation times (∼10 000 s), which substitute for ∼1% of PO43−; (ii) silicate nanoinclusions containing Q2, Q1, and Q0 sites with T1,Si ∼ 100 s, which account for most of the silicon; and (iii) crystalline Q4 (SiO2) with long T1,Si. Sensitivity was enhanced >100-fold by 29Si enrichment and refocused detection. The inclusions in both samples have a diameter of ∼8 nm, as proved by 29Si{31P} REDOR dephasing on a 30-ms time scale, which was simulated using a multispin approach specifically suited for nanoparticles. 29Si CODEX NMR with 30-s 29Si spin diffusion confirms that an inclusion contains >10 Si (consistent with the REDOR result of >100 Si per inclusion). Overla.
The integrated supply chain model considering process mean, replenishment cycle time and credit period

Abstract Banu and Mondal (2018) proposed an integrated inventory model with/without manufacturer’s product warranty and customer’s trade credit. Their model needs to obtain the optimal product warranty, retailer’s cycle length, and customer’s credit period with the maximum of the expected total profit per unit time. Their model can be further applied in the process control. In this paper, the authors present a modified Banu and Mondal’s model without product warranty for obtaining the optimal process mean, retailer’s replenishment cycle time, and customer’s trade credit period. Assume that the product quality is normally distributed with unknown process mean, known standard deviation, and larger-the-better characteristic. Numerical example and sensitivity analysis of some parameters will be provided for illustration.
Proteomic analysis of Lactobacillus casei in response to different pHs using two-dimensional electrophoresis and MALDI TOF mass spectroscopy

Background and Objectives: Lactobacillus casei, an acid-resistant bacterium, has a protective role against the pathogens. So we aimed to determine the proteome of Lactobacillus casei ATCC39392 strain in response to different pHs of 5 and 7 using proteomic analysis. Materials and Methods: Supernatant and bacterial extraction of Lactobacillus casei ATCC39392 adapts at pHs 5 and 7 were isolated using sodium dodecyl sulfate–polyacrylamide gel and two-dimensional gel electrophoresis. The comparison of results showed that 7 protein spots were seen in pH 5 but not in pH 7. Afterward, they were excised and sent for Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) to be identified. Results: Seven different proteins (four secretory and three structural) with different roles in human body health were identified. Prescribed proteins include putative cell wall associated Hydrolase, Glycoside Hydrolase, beta-N-Acetyl hexosaminidase, Histidine Kinase, Chaperonin, metal dependent Hydrolase and Lysozyme. Conclusion: Seven isolated proteins with anti-cancer and digestive impresses are proper subjects in therapy or drug delivery approaches especially oral drug usage for protection against stomach acidic area.
Conflict and international education: experiences of Yemeni international students

ABSTRACT The ongoing conflicts in Yemen have affected the entire community. This article focuses on students from Yemen and the continuing impact of the conflict on their educational experiences in China. A case-study methodology and in-depth interviews with ten participants reveal a combination of pre-departure, travelling, registration and financial challenges, the loss of opportunities and hopes, and social and psychological pressures. As a result of the research, conclusions are that the Yemeni government needs to re-consider providing monthly stipends for the students and neighbouring nations (e.g. Oman) need to facilitate the procedures for students’ entry visas. Further, it is argued that the Chinese government and universities could provide additional assistance for Yemeni students, re-consider their policies concerning application outcomes and registration procedures, and provide waivers for tuition fees. Implementing these measures could have a positive impact on the experiences of Yemeni students in China and on other students from conflicted areas.
Biofilmes nanocompósitos obtidos de isolado proteico de corvina (Micropogonias furnieri) e Montmorilonita: avaliação das propriedades físicas, mecânicas e de barreira

O objetivo deste trabalho foi avaliar as propriedades de biofilmes nanocompositos de isolado proteico de corvina (Micropogonias furnieri) com argila organofilica. Inicialmente, foi obtido isolado proteico de corvina (IPC) utilizando-se o processo de mudanca de pH. O IPC foi obtido a partir de subprodutos da industrializacao de corvina. Para o desenvolvimento dos filmes, foi executado um planejamento experimental de Box e Behnken, com tres niveis de IPC (2; 3,5; 5 g.100 g-1 de solucao), argila montmorilonita MMT (0,3; 0,5; 0,7 g.100 g-1 de solucao) e glicerol (25, 30, 35 g.100 g-1 IPC). Os filmes polimericos foram desenvolvidos pela tecnica de casting. Os valores de resistencia a tracao variaram entre 7,2 e 10,7 MPa, e os valores de alongamento, de 39,6 a 45,8%. Os valores de permeabilidade ao vapor de agua (PVA) variaram entre 3,2 e 5,5 g mm m-2 d-1kPa-1. O IPC apresentou teor medio de proteina de 97,87% (b. s.). Pode-se concluir que os filmes nanocompositos produzidos a partir de IPC com MMT foram promissores, desde o ponto de vista das propriedades mecânicas, da aparencia visual e do facil manuseio ate a baixa permeabilidade ao vapor de agua e a baixa solubilidade. Com relacao as propriedades mecânicas, as concentracoes de IPC e MMT foram os principais fatores que influenciaram o desenvolvimento dos filmes nanocompositos. Os resultados obtidos no planejamento experimental utilizado indicaram que 3,5 g de IPC.100 g-1 de solucao, 0,5 g de MMT.100 g-1 de solucao e 30 g de glicerol.100 g-1 IPC seriam os parâmetros ideais para a preparacao de filmes nanocompositos por casting.
Extraction and Functional Properties of Water‐Soluble Dietary Fiber from Apple Pomace

The extraction of water-soluble dietary fiber (SDF) from apple pomace (AP) by cellulase, microwave- and ultrasound-assisted methods was studied in comparison with conventional acid method. The functional properties of extracted SDFs were further evaluated, and the speciality of each method was clarified in order to suggest the right method to adopt for practice. Results indicated that AP is rich in SDF, which is significantly potential to be applied in food processing. Acid hydrolysis of AP gave 10.3% of SDF, whereas ultrasound-assisted extraction (UAE) provided a yield of 16.4% after 40 min of sonication. Microwave-assisted extraction (MAE) gave a slightly lower yield (14.9%) than UAE, but it showed a drastic efficiency, wherein the yield was achieved after 2 min of irradiation. The hydrolysis of AP by cellulase occurred with the highest SDF yield (18.7%) among all the methods used. The functional properties of SDF were improved by UAE, MAE and cellulase extraction, wherein the water retention and swelling capacities were increased more considerably than the oil retention capacity. Especially, cellulase showed a remarkable performance in improving the hydration property. Practical Applications A large amount of apple pomace (AP) was produced as the by-product of apple processing in China. Its disposal is of significance in consideration of resource utilization and environmental protection. Therefore, the results of this study can promote the full use of AP and similar industrial wastes, and also help to avoid possible pollution. In addition, the comparison of acid, cellulase, microwave- and ultrasound-assisted methods suggests the right method to adopt SDF extraction method for practice.
In Vitro New Capillary Formation with Eight Metal Ions of Dental Biomaterials

74 INTRODUCTION New capillary formation is indispensable for tissue regeneration. The influences of metal ions released from metal prostheses on angiogenesis in oral tissue remain unclear . The development of alloys containing metal ions with marked angiogenic effects may promote active oral tissue regeneration. In this study, we evaluated the influences of 8 types of metal ion (Ag, Au, Cu, In, Ni, Pd, Ti, and Zn), which are major components of gold-silver-palladium and nickel-titanium alloys used in the metallic dental biomaterials, on the in vitro formation of new blood vessels using a human angiogenesis kit (Kurabo, Japan) .
Decadent Developmentalism

Brazil features regularly in global comparisons of large developing economies. Yet since the 1980s, the country has been caught in a low-level equilibrium, marked by lackluster growth and destructive inequality. One cause is the country's enduring commitment to a set of ideas and institutions labelled developmentalism. This book argues that developmentalism has endured, despite hyperactive reform, because institutional complementarities across economic and political spheres sustain and drive key actors and strategies that are individually advantageous, but collectively suboptimal. Although there has been incremental evolution in some institutions, complementarities across institutions sustain a pattern of 'decadent developmentalism' that swamps systemic change. Breaking new ground, Taylor shows how macroeconomic and microeconomic institutions are tightly interwoven with patterns of executive-legislative relations, bureaucratic autonomy, and oversight. His analysis of institutional complementarities across these five dimensions is relevant not only to Brazil but also to the broader study of comparative political economy.
