Clinical and Radiological Features of Interstitial Lung Diseases Associated with Polymyositis and Dermatomyositis

Polymyositis and dermatomyositis are autoimmune idiopathic systemic inflammatory diseases, characterized by various degrees of muscle inflammation and typical cutaneous lesions—the latter found in dermatomyositis. The underlying pathogenesis is characterized by a high level of uncertainty, and recent studies suggest diseases may have different immunopathological mechanisms. In polymyositis, components of the cellular immune system are involved, whereas in dermatomyositis, the pathogenesis is mainly mediated by the humoral immune response. The interstitial lung disease occurs in one-third of polymyositis and dermatomyositis patients associated with worse outcomes, showing an estimated excess mortality rate of around 40%. Lung involvement may also appear, such as a complication of muscle weakness, mainly represented by aspiration pneumonia or respiratory insufficiency. The clinical picture is characterized, in most cases, by progressive dyspnea and non-productive cough. In some cases, hemoptysis and chest pain are found. Onset can be acute, sub-acute, or chronic. Pulmonary involvement could be assessed by High Resolution Computed Tomography (HRCT), which may identify early manifestations of diseases. Moreover, Computed Tomography (CT) appearances can be highly variable depending on the positivity of myositis-specific autoantibodies. The most common pathological patterns include fibrotic and cellular nonspecific interstitial pneumonia or organizing pneumonia; major findings observed on HRCT images are represented by consolidations, ground-glass opacities, and reticulations. Other findings include honeycombing, subpleural bands, and traction bronchiectasis. In patients having Anti-ARS Abs, HRCT features may develop with consolidations, ground glass opacities (GGOs), and reticular opacities in the peripheral portions; nonspecific interstitial pneumonia or nonspecific interstitial pneumonia mixed with organizing pneumonia have been reported as the most frequently encountered patterns. In patients with anti-MDA5 Abs, mixed or unclassifiable patterns are frequently observed at imaging. HRCT is a sensitive method that allows one not only to identify disease, but also to monitor the effectiveness of treatment and detect disease progression and/or complications; however, radiological findings are not specific. Therefore, aim of this pictorial essay is to describe clinical and radiological features of interstitial lung diseases associated with polymyositis and dermatomyositis, emphasizing the concept that gold standard for diagnosis and classification–should be based on a multidisciplinary approach.

Subharmonic resonance of Venice gates in waves. Part 1. Evolution equation and uniform incident waves

For flood protection against storm tides, barriers of box-like gates hinged along a bottom axis have been designed to span the three inlets of the Venice Lagoon. While on calm days the gates are ballasted to rest horizontally on the seabed, in stormy weather they are raised by buoyancy to act as a dam which is expected to swing to and fro in unison in response to the normally incident sea waves. Previous laboratory experiments with sinusoidal waves have revealed however that neighbouring gates oscillate out of phase, at one half the wave frequency, in a variety of ways, and hence would reduce the effectiveness of the barrier. Extending the linear theory of trapped waves by Mei et al. (1994), we present here a nonlinear theory for subharmonic resonance of mobile gates allowed to oscillate about a vertical plane of symmetry. In this part (1) the evolution equation of the Landau–Stuart type is first derived for the gate amplitude. The effects of gate geometries on the coefficients in the equation are examined. After accounting for dissipation effects semi-empirically the theoretical results on the equilibrium amplitude excited by uniform incident waves are compared with laboratory experiments.
Free Vibration of Laminated Orthotropic Cylindrical Shells

Vibration characteristics of thin laminated orthotropic cylindrical shells are investigated. The theory, based on the Kirchhoffean hypothesis regarding deformation, can accommodate shells composed of an arbitrary number of bonded layers, each with a different thickness and different elastic orthotropic properties. Donnell‐type equations expressed in terms of the reference surface displacements are employed, and the effects of initial extensional forces in the shell are included. The frequency equation for a simply supported cylinder is derived. Next, an iterative procedure for determining the natural frequencies of a shell under an arbitrary set of homogeneous boundary conditions is described in detail. Specialization of present results to laminated orthotropic plates is indicated.
Simulating cyanide fishing: photosynthetic effects of short-term cyanide exposure in three different hermatypic coral species

ABSTRACT Since the 1960s the demand for ornamental aquarium fish has grown steadily and consequently cyanide fishing is still a popular fishing method despite its prohibition. This poses a severe threat to coral reefs in Southeast Asia. This study aimed to investigate the short-term stress reaction on photosynthetic yield in the tissues of three different hard coral colonies (branching growth forms Pocillopora damicornis and Seriatopora hystrix, and massive Porites lobata) to initially high and then decreasing cyanide exposure, mimicking cyanide fishing by fishermen. Experiments were performed both in situ in the coral reefs of the Marine Protected Area Pulau Pieh, West Sumatra, Indonesia, and in the aquaria facilities of ZMT in Germany. A Diving-PAM fluorometer was used for in vivo stress assessment of the holobiont. While in all species the photosynthetic efficiency was significantly reduced right after cyanide application, the massive species displayed much lower ΔF/Fm’ values. After three days in cyanide-free water all three coral species recovered to initial values of Fv/Fm, except for P. lobata. No bleaching or discolouration was detected by the conclusion of the experiment after 38 days. Especially Indonesian reefs with massive corals may be therefore more severely impacted by cyanide fishing since the retention time of the water in these reefs is longer than in reefs that consist primarily of branching corals. This might have implications for the management of different reef parts of the MPA.
THERMAL BUCKLING AND BENDING ANALYSES OF CARBON FOAM BEAMS SANDWICHED BY COMPOSITE FACES UNDER AXIAL COMPRESSION

The bending and critical buckling loads of a sandwich beam structure subjected to thermal load and axial compression were simulated and temperature distribution across sandwich layers was investigated by finite element analysis and validated analytically. The sandwich structure was consisted of two face sheets and a core, carbon fiber and carbon foam were used as face sheet and core respectively for more efficient stiffness results. The analysis was repeated with different materials to reduce thermal strain and heat flux of sandwich beams. Applying both ends fixed as temperature boundary conditions, temperature induced stresses were observed, steady-state thermal analysis was performed, and conduction through sandwich layers along with their deformation nature were investigated based on the material properties of the combination of face sheets and core. The best material combination was found for the reduction of heat flux and thermal strain, and addition of aerogel material significantly reduced thermal stresses without adding weight to the sandwich structure.
Electromagnetic Material Characterization using a Partially-Filled Rectangular Waveguide

Electromagnetic material characterization measurements are an important aspect of modern design. Rectangular waveguides are often used in the material characterization process to facilitate measurement since they are readily available and because rectangular samples can be easily machined and placed in the cross-sectional plane of the waveguide for reflection and transmission testing and subsequently analyzed using a simple theory [1, 2]. However, this technique can produce unacceptably large errors for high loss or highly reflecting samples due to a poor signal-to-noise ratio (SNR) for the transmission measurement.In this paper, a partially-filled waveguide method is presented that enhances transmission quality and accuracy in electromagnetic material characterization measurements. The partially-filled waveguide geometry improves transmission but leads to the excitation of higher-order modes. A mode-matching technique is developed here to accommodate the resulting waveguide discontinuity and a Newton root search method is utilized to subsequently extract the electromagnetic properties of the test sample. Experimental measurements for several materials will be presented at X-band frequencies (8–12 GHz) to verify the theoretical analysis.
The influence of profitability, leverage, capital intensity, and firm size on tax aggressiveness during covid-19 pandemic

In Indonesia, businesses have recently engaged in tax aggressiveness. The Republic of Indonesia's Ministry of Finance estimates that by the middle of 2020, tax evasion by businesses as reported by the Tax Justice Network might result in a loss of roughly Rp 68.7 trillion annually in worldwide tax collections. State tax income is reduced as a result of this. Additionally, the Covid-19 pandemic has increased economic instability. The purpose of this study is to investigate the impact of profitability, leverage, capital intensity, and business size on tax aggressiveness during Covid-19 pandemic. Profitability, leverage, capital intensity, and company size are the independent variables in this study, while firm age is the control variable. The dependent variable is tax aggressiveness, which is determined by the effective tax rates (ETR). In the 2020–2021 timeframe, 170 manufacturing companies listed on the Indonesia Stock Exchange were chosen as the target of observation. Using the purposive sampling method, a sample of 100 manufacturing businesses was obtained based on predetermined criteria. The findings revealed that profitability, leverage, and capital intensity all had a considerable impact on tax aggressiveness. While the size of the business has no substantial impact on tax aggressiveness. Age of the firm, which serves as the control variable, has a negative and considerable impact on tax aggressiveness.
Dynamical Approach Study of Spurious Steady-State Numerical Solutions of Nonlinear Differential Equations, Part III. The Effects of Nonlinear Source Terms in Reaction-Convection Equations

Abstract The objective of this paper is to investigate how well numerical steady-state solutions can mimic true steady-states of a model nonlinear reaction-convection. In order to assess the possible'sourcesoferrors,slowconvergence and nonconvergence of steady-state numerical solutions when using the time-dependent approach, six different numerical aspects are addressed. First, spurious stable and unstable steady-state numerical solutions (numerically irrelevant solutions) can be independently introduced by spatial and temporal discretizations satisfying the same boundary condition and initial data. Second, the various numerical treatments of the reaction term can affect the stability of the spurious as well as the exact steady-state solutions. Third, the time discretization can destabilize the spurious stable steady-state numerical solutions that are introduced by the spatial discretizations or vice versa. Fourth, for a given finite difference method, the strength of the coefficient of the convection ter.
Achieving weight loss through a community-based, telewellness programme: A randomised controlled trial

Objectives: To (1) determine the weight-reducing effect of the Koa Family Program (KFP), a community-based, telewellness obesity intervention and (2) examine the impact of the KFP on improving weight-related health indicators. Design: Randomised controlled trial. Setting: Community-based in Sacramento, California, USA. Methods: Seventy women with overweight or obesity (25 ⩽ BMI < 40), aged 21–45 years and with low income (⩽ 185% of the US Federal Poverty Level) were randomly assigned to an intervention (n = 34) or control (n = 36) group. Data were collected by phone-administered questionnaire at weeks 0, 18 and 25. The intervention consisted of three components: (1) weekly, health coach-led, health education meetings on Zoom; (2) social media support through texting and private Facebook groups; and (3) a tree planting and stewardship campaign. The treatment effect on outcome measures (95% confidence intervals) was analysed with adjustment for variables including age, race/ethnicity, education and intake of fruit and vegetables. Results: The overall treatment effect of the KFP was weight loss at both Week 18 (–7.69 pounds [p < .000; 95% confidence interval (CI) = −11.97 to −3.41]) and Week 25 (−7.72 pounds [p = .002; 95% CI = −13.02 to −2.42]) of the study. KFP-associated improvements in diet, physical activity, stages of change and self-efficacy were also observed. Conclusions: The KFP resulted in weight loss significant at individual and population levels.
Wave propagation in a condensed medium with N transforming phases: Application to solid‐I–solid‐II–liquid bismuth

Constitutive assumptions of local thermal and pressure equilibrium in a mixture of N transforming phases allow construction of a constitutive equation of a generalized Maxwellian form suitable for studying the kinetics of phase transformations induced by shock‐wave loading. This equation relates the pressure rate to the strain rate and the phase change rate, the latter being expressed as the time derivative of a vector which has components equal to the mass fractions of the constituent phases. A separate kinetic equation is required for evolution of this composition vector. Coefficients appearing in the constitutive equation depend only on properties that the mixture displays with a frozen composition which in turn depend directly on properties of the pure‐phase components of the mixture. The constitutive equation is applied to solid‐I–solid‐II–liquid bismuth (N=3). When wave propagation calculations on bismuth are compared to previous theory and experiments, a lower bound on the melting rate of 4 μsec−1 .
Detection of Absorption-Line Features in the X-Ray Spectra of the Galactic Superluminal Source GRO J1655–40

We report the detection of iron K-absorption lines in the energy spectra of the superluminal jet source GRO J1655-40. We observed the source with ASCA on four occasions from 1994 through 1996. Significant absorption-line features were found at 6.63 ± 0.07 keV when the X-ray intensity was low (0.27-0.57 crab) and at 6.95 ± 0.10 keV when the intensity was high (2.2 crab). The former are interpreted as resonance absorption lines from helium-like iron and the latter are those from hydrogen-like iron, respectively. This gives direct evidence for the presence of highly ionized plasma in a nonspherical configuration in the vicinity of the black hole. The change of the ionization state of iron suggests that the plasma is photoionized by X-ray irradiation. The observed equivalent width (about 60 eV for the helium-like Kα line) and the ionization parameter ξ (~103) constrain the size of the plasma to ~1010 cm. The similarity of these properties to those of the other superluminal source GRS 1915+105 may imply some connection between the presence of such highly ionized plasma and the formation of relativistic jets.
Level of Estrogen in Females—The Different Impacts at Different Life Stages

Historically, a high level of estrogen in women is regarded as the signature for a longer lifespan than men. Estrogen is known to be responsible for the development and regulation of the female reproductive system and secondary sex characteristics. Ovariectomy brings on numerous complications such as early menopause, heart disease, and osteoporosis. Thus, ovariectomy impacts the long-term health and lifespan of women. However, the level of estrogen at different life stages should be managed differently. Life quality can be measured in many ways, but mainly it relates to how an individual is doing in terms of being healthy, comfortable, and able to participate in or enjoy life experiences. First of all, ovariectomy not only reduces the level of estrogen but also destroys the reproductive metabolism and potentially other metabolism functions; it may also reduce the lifespan because of the overall impact, not necessary due to the low level of estrogen. Secondly, according to the principal law of the lifespan (PLOSP), the impacts of ovariectomy at different life stages will be different. The objective of this article is to provide readers with a new view of the research on estrogen. Based on the PLOSP, we recapture the estrogen levels at different life stages and explore potential alternative approaches to the manipulation of the levels of estrogen based on the biological features of the difference life stages. Thus, a low level of estrogen in the early life stage may make a woman live longer than a woman with a normal level of estrogen. However, a low estrogen level does not equal ovariectomy. Here, we explain the different impacts of the estrogen levels during different life stages; the effects on the lifespan of the manipulation of estrogen levels at different life stages; and the differences among the estrogen levels, ovariectomy effects, life stages, and lifespan. The personalized manipulation of estrogen levels and relevant growth factors according to the characterization of the life stages may be able to extend the heathy lifespan of women.
Analysis of the Effect of Halal Awareness, Subjective Norms, Attitudes and Intentions on Consumer Interest and Use of Halal Cosmetics

Every Muslim-majority country, including Indonesia, has a growing Muslim population accompanied by rising Muslim incomes. As a result, the demand for halal goods has increased, both in Indonesia and in other countries where the majority are Muslim. Causal association strategy and quantitative approach were used in the research design. Causal relationship means a causal relationship. The quantitative approach is a research method that examines the relationship between variables using numerical data. Halal awareness is the ability to understand, feel, and be aware of events and objects or products that are categorized as halal. The results of this study indicate that there is a significant positive effect of halal awareness on consumer interest, with the obtained value of cr between the effect of halal awareness on consumer interest is 2.423 and p-value = 0.039. Because the value of cr is greater than 1.96 (2.423 > 1.96), and the p-value is less than (0.035 < 0.05). Halal awareness of the Mandailing Natal community is driven by the high religiosity of the community. There is a significant positive influence regarding the effect of halal awareness on consumer interest in the Mandailing Natal community. There is a significant positive effect on the influence of the subjective norm variable on consumer interest in the Mandailing Natal community.
Corporate Social Responsibility and Energy-Related Pro-Environmental Behaviour of Employees in Hospitality Industry

Tourism and hospitality are at a crossroads. The growth and developmental potential of these industries indicate the economic benefits for an associated nation at one end. However, the environmental issues related to tourism and hospitality create challenges for the administration at another end. In most cases, a sheer amount of carbon emission in hospitality lies with energy consumption, especially electrical energy. However, past studies on environmental management have mainly focused on the supply side of energy (production) and left the terrain of the demand side (consumption by individuals) unattended. Recently, behavioral scientists have indicated that corporate social responsibility (CSR) actions of a firm can promote sustainable behavior among individuals, including employees. We tend to spark this discussion from an energy consumption perspective by investigating the relationship between CSR and energy-related pro-environmental behavior of employees (EPB) in the hospitality sector of a developing country (Pakistan). To understand the underlying mechanism of this relationship, this study proposes the mediating role of green intrinsic motivation (GIM) and the moderating role of human emotions, e.g., employee admiration (ADM). We developed a theoretical model for which the data were gathered from different hotel employees with the help of a questionnaire. We used structural equation modeling for hypotheses testing. The empirical evidence indicated that CSR significantly predicts EPB, and there is a mediating role of GIM. The study also confirmed that ADM moderates this relationship. The findings of this study will be helpful for hotel administration to understand the profound importance of CSR-based actions to promote energy-related sustainable behavior among employees, e.g., EPB. Other implications for theory and practice have been highlighted in the main text of this draft.
Some Contributions to the Homogenization of Macroscopically Isotropic Composites

The development of homogenization models and solutions, either analytic or numerical, is a difficult task. Due to the integral nature of equations, the result has a good chance to fall within the theoretical bounds and as long as it is there - there might be no indication for any mistake. The difficulty of the homogenization stems not from the involved mathematical concepts, but rather from the little, to at times, no difference between something correct and something that just happens to look plausible. In this work it is argued that the Hashin-Shtrikman expressions are not bounds, but rather boundaries of the solution (hyper)surface. It is also shown that the well known Hill condition is not a necessary ingredient for the homogenization. Using a few homogenization concepts, a complete system of equations describing the macroscopic behavior of the heterogeneous materials has been derived. This system possesses a simple solution in the isotropic case.
