Predicting the Mechanical Properties of Bimrocks with High Rock Block Proportions Based on Resonance Testing Technology and Damage Theory

Block-in-matrix-rocks (bimrocks) are very complicated geological masses that cause many challenging problems during the design and construction of engineering projects, such as parameter determination and landsliding. Successful engineering design and construction depends on a suitable constitutive model and reliable design parameters for geological masses. In this paper, the vibration attenuation signal of welded bimrocks was obtained and studied using resonance test technology. Combined with a uniaxial compression test, a constitutive model was proposed to describe the mechanical behavior of welded bimrocks. On this basis, the relations between the dynamic elastic modulus and the physical parameters of bimrocks were established, which included macroscopic mechanical parameters and damage constitutive parameters. Consequently, a new technological process was proposed to provide quick identification of the mechanical properties of welded bimrocks. The results indicate that the dynamic elastic modulus is highly correlated with the rock block proportion (RBP) and uniaxial compression strength (UCS). It is an effective parameter to predict the strength of the bimrocks with high RBPs. Additionally, the proposed constitutive model, which is based on damage theory, can accurately simulate the strain softening behavior of the bimrocks. Combining the resonant frequency technology and the proposed constitutive model, the complete stress strain curve can be obtained in a rapid and accurate manner, which provides a further guarantee of the stability and safety of underground engineering.
Punjabi Sikh women's arthritis self management experiences

3 Abstract Self-management interventions enhance the health self-management techniques and physical and psychological health outcomes among people with long-term health conditions (LTHCs). Few individuals from South Asian backgrounds attended the pilot phase of one such intervention: the Expert Patients Programme (EPP), a community-based self-management course. This raised concerns about exacerbating health inequalities. South Asian people have increased prevalence and severity of certain musculoskeletal conditions, yet little is known about their experiences of living with and self-managing these. This research aimed to rectify these omissions, by describing Punjabi Sikh women's experiences of living with and self-managing arthritis, and identifying barriers and facilitators to EPP. Three studies explored White and Punjabi Sikh EPP tutors‟ experiences of delivering EPP to South Asian attendees, and Punjabi Sikh women's experiences of living with and self-managing arthritis, both before and after they attended a Punjabi-language EPP. White and Punjabi Sikh tutors' sometimes dichotomous experiences of delivering EPP to South Asians, captured barriers to South Asian people's attendance, engagement and self-management. Facilitators identified included the need for sensitive tailoring of the Course, involving the Punjabi Sikh community. The Punjabi Sikh women's vibrant experiential accounts revealed the detrimental psychological and physical consequences that arthritis had upon their lives. Highly versatile in their proactive arthritis self-management prior to attending EPP, participants' refined techniques encompassed combinations of medication and Indian remedies, empowered by their religious and spiritual values. Following EPP attendance, the participants reported psychological and physical improvements in their arthritis. Thus, this Study established Punjabi Sikh
Myoglobin dynamics in serum in patients with coronary heart disease before and after of coronary stenting

Actuality: Cardiovascular diseases, including coronary heart disease (CHD), occupy an important role in the structure of morbidity and mortality in most developed countries including Russia. [2] Currently, the prevalence of coronary heart disease in the general population of Russia is 13,5 ± 0,1 %, among men – 14,3 ± 0,3 %, women – 13,0 ± 0,2 % [6]. This trend of disease development in the population poses in front of a modern cardiology the problem of early diagnosis, risk assessment, with the necessity of timely initiation of therapeutic measures. Despite the intensive development of noninvasive methods of treatment, coronary artery stenting or coronary artery bypass grafting. Each year there are performed about two million percutaneous coronary intervention (PCI) in the world, more than 90 % of which are of coronary stenting [1, 8]. In the literature, it has been recently appeared the term “minor myocardial damage” that arise in the PCI and is identified only by the definition for cardiac markers. One of cardio-speсific markers is myoglobin – low molecular heme-containing protein that is found in all muscle cells. Its molecular weight is 18 kDa [3, 7]. Therefore, damaged myocardium myoglobin readily diffuses through cell membranes of damaged muscle. Its content in the serum of patients with myocardial infarction increase in 2 hours after onset of symptoms [4, 5]. Thus, myoglobin is an early enough sensitive marker. Researches, devoted to the studies, we have not seen in the literature thus the aim of research has been formulated. The aim of research: To determine the degree of ischemic and reperfusion myocardial injury during percutaneous coronary intervention by studying the dynamics of myoglobin in the blood serum of patients with coronary heart disease: stable stenocardia of II-III functional classes.
Focusing the L-Band Spaceborne Bistatic SAR Mission Data Using a Modified RD Algorithm

LuTan-1 [(LT-1), i.e., TwinSAR-L] mission is an innovative spaceborne bistatic synthetic-aperture radar (BiSAR) mission focusing mainly on differential interferometry, which will be launched in 2020. This article introduces some important aspects of the LT-1 mission for the first time, including the formation configuration, imaging mode, application scenarios, and the efficient baselines between the master satellite and the slave satellite. To realize the high accurate topography and deformation measurements, a wide swath BiSAR focusing algorithm with phase reserving ability should be developed. This article proposes a modified bistatic range-Doppler algorithm based on 2-D principle of stationary phase spectrum, which reduces the phase error introduced by the root term expansion and has an excellent focus performance and a good phase reserving ability. Finally, the spaceborne bistatic simulation experiments using orbital parameters and imaging mode of the LT-1 mission, including point targets and scene targets, are utilized to illustrate the validity and accuracy of the proposed algorithm.
Multiple‐Instance Superparameterization: 2. The Effects of Stochastic Convection on the Simulated Climate

The cloud‐permitting model (CPM) of the superparameterized Community Atmosphere Model (SP‐CAM) is a stochastic parameterization. As reported in a companion paper, we have created a variant of SP‐CAM, called MP‐CAM, that uses the averaged feedback of 10 independent two‐dimensional CPMs in each global model column, in place of the single CPM of SP‐CAM. This ensemble‐averaged feedback is interpreted as an approximation to the feedback from a deterministic parameterization. We present evidence that the multiple‐instance superparameterization of MP‐CAM is indeed more deterministic than SP‐CAM. The climates of the SP and MP configurations are compared, giving particular attention to extreme precipitation events and convectively coupled large‐scale tropical weather systems, such as the Madden‐Julian Oscillation. A number of small but significant changes in the mean state climate are uncovered, and the deterministic parameterization slightly degrades the Madden‐Julian Oscillation simulation.
Local Degradation in Soft Magnetic Materials: A Simplified Modeling Approach

Manufacturing processes, such as cutting, welding, or assembling originate mechanical and thermal effects that locally introduce residual stresses. Consequently, the magnetic material shows a decrease of magnetic permeability and an increase of hysteresis losses. The adoption of catalogue data for electrical machines simulation thus follows low accuracy of the results. This article deals with effective modeling of the degradation of relative permeability and iron losses in soft magnetic materials due to manufacturing processes. The degradation profile is assessed by means of experimental activity conducted on a set of ring samples where the damaged material has been removed through electrical discharge machining. The proposed modeling approach is particularly relevant when it is implemented in numerical simulation tools.
Petrogenesis and Shock Metamorphism of Basaltic Lunar Meteorites Northwest Africa 4734 and 10597

We present comprehensive compositional and mineralogical results on two basaltic lunar meteorites Northwest Africa (NWA) 4734 and NWA 10597 to constrain their igneous mineralogy and metamorphic characteristics, and examine the potential pairing relationship among them and other meteorites (e.g., basaltic lunar meteorites collected from LaPaz Icefield, Antarctica (LAPs)). NWA 4734 and NWA 10597 are low‐Ti (3.2–3.5 wt.% TiO2), low‐Al (10–12 wt.% Al2O3), low‐K (880–1,300 ppm K) mare basalts derived from evolved parental magma (Mg# (molar Mg/[Mg + Fe] × 100) = 33.6–38.3) and are mostly composed of pyroxene (52.7–55.5 vol.%), plagioclase/maskelynite (27.5–29.3 vol.%), olivine (6.7–7.6 vol.%), and late‐formed components (i.e., mesostasis). Pyroxene and olivine in these two meteorites exhibit a multimodal compositional distribution, indicating multiple generations of these mafic minerals, which correspond to different evolution phases (e.g., magma chamber, ascending, and eruption) during the solidification of the basaltic parental magma. Immiscibility played an important role in the evolution of the late‐stage melts, inducing fractionation involving Fe‐rich and Si, K‐rich melts within mesostasis. Considering the extensive partial transformation of plagioclase to maskelynite across the sections, the average shock pressure endured by NWA 4734 and NWA 10597 is probably 23–29 GPa, which is consistent with the pressure condition (below 29.8 GPa) recorded by quartz. Similar textures, bulk composition, modal mineral proportions, and mineral compositions indicate that NWA 4734, NWA 10597, and the LAPs most likely originated from the same region of the Moon and both experienced intensive shock events.
Rendre compte de sa compétence dans un portfolio : mieux comprendre les besoins des étudiants pour mieux les accompagner

Asking students to document and demonstrate their mastery of learning outcomes or development of competencies (Tardif, 2006) by producing a portfolio engages them in a complex individual task. It is therefore necessary to accompany each of them in this process of "reporting" on his own learning. This research analyzes the "Traces" seminar designed to support the production of a portfolio integrated into two courses of a Master's degree in Education. Students share and discuss the traces of their competence development. However, this seminar does not seem to fulfill all its intentions because many students fail the final evaluation. In the light of the theoretical framework of selfregulation of learning (Cartier & Butler, 2016) as well as various works questioning the use of traces (Cahour & Licoppe, 2010) and accompanying strategies (Poumay, 2017 ; Saint-Pierre, 2004), this article discusses the pedagogical conditions that seem to support the quality of these complex productions. The analyzes make it possible to highlight three levels of needs of the students: to understand the requirements of the activity, to appropriate the process and to evaluate his/her own performance. Better understanding of these could not only help students in their learning, but also support the reflection of teachers and researchers, willing to optimize these activities aimed at an eminently complex performance: reporting on his/her own competence.

Diseño analítico de filtros multibanda con líneas de transmisión multiconductoras y stubs en abierto

Resumen—A new topology for implementing multiband bandpass filters is presented in this paper. Two identical shortcircuited multiconductor transmission lines (MTL) and several shunt open stubs are interconnected to achieve the desired frequency response. Using this configuration, zeros are forced in the passband of the MTL, creating a multiband bandpass filter. As both, the MTLs and the stubs are distributed elements, spur-line band-stop filters are added in order to mitigate the first replicas of the structure. To assess the developed theory, a prototype consisting of a 4 fingers-MTL and two shunt open stubs is simulated, showing a good agreement between analytical and simulated results. Furthermore, it is possible to establish a design criterion that allows to synthesize multiband responses, varying just some parameters of the MTLs and the stubs.
Transitivity properties of ternary fuzzy relations

Recently, we have introduced six types of composition of crisp ternary relations. These compositions are close in spirit to the definition of the composition of binary relations. In this note, we extend these notions to the fuzzy setting. Based on these types of composition, we introduce several types of transitivity of a ternary fuzzy relation and investigate their properties.
Pretrial Release in Virginia: Investigating the Influence of Defendant Characteristics and Community Type on Pretrial Outcome

PRETRIAL RELEASE IN VIRGINIA: INVESTIGATING THE INFLUENCE OF DEFENDANT CHARACTERISTICS AND COMMUNITY TYPE ON PRETRIAL OUTCOME Marie L. VanNostrand Old Dominion University, 2000 Chair: Dr. Wolfgang Pindur This study identified defendant characteristics that are related to pretrial outcome (success or failure pending trial) in Virginia. The study also investigated the potential differences in predictors across community types (Large Urban, Small Urban, Mixed, and Rural). Identification of factors that are predictors of outcome, as well as any differences across community types, can assist judicial officers in making the bail decision. The bail decision, to release or incarcerate a defendant pending trial, is a monumental one. Judicial officers must attempt to fairly and equitably balance the rights and needs of the defendant with those of the public at large. The successful identification of predictors of pretrial outcome, if used by judicial officers, can improve bail decisions and result in an increase to public safety, a reduction in the potential for disparity in bail decisions, the protection of the presumption o f innocence, and an improvement in the operation of the criminal justice system. The Beeley Theory o f Pretrial Risk Prediction guided this research. This theory states that individual defendant characteristics including current charge, criminal history, social history, and personal characteristics, are related to pretrial outcome and should be considered in the bail decision-making process. The research also tested the Assumption Reproduced with permission of the copyright owner. Further reproduction prohibited without permission. of Community Differences for the first time. This assumption refers to the belief that the predictors of pretrial outcome are different depending on the community type in which a defendant resides. The Virginia Department of Criminal Justice Services provided the database for this research. The database contained 1,971 valid cases with 1 dependent variable (outcome) and 50 independent variables that were measures o f demographics, health, community and general stability, criminal history, and community type. The cases were collected from seven Virginia localities representing the four community types. The data analysis consisted of descriptive, bivariate (Chi-Square and Mann-Whitney U), and multivariate (Binary Logistic Regression) statistics. The Beeley Theory of Pretrial Risk Prediction and the Assumption of Community Differences were both supported. Sixteen defendant characteristics were related to pretrial outcome. The best predictors of outcome varied across community types. Recommendations for public policy and future research are presented. Reproduced with permission of the copyright owner.

Effects of Hot Switching and Contamination on Contact Reliability of Pt-Coated Microswitches

Hot switching and hydrocarbon-induced contact activation limit the lifetimes and exacerbate the surface erosion/damage in switches. However, the relative effects of voltage and contamination have not been studied. We report on these effects in Pt-coated microswitches. Long lifetime, as determined from electrical contact resistance (ECR) data versus switch cycle count, was observed under cold switching conditions. Cycling under hot switching conditions was performed at different contact voltage levels <inline-formula> <tex-math notation="LaTeX">$V_{c}$ </tex-math></inline-formula> in: 1) a clean, hydrocarbon-free environment and 2) the presence of 40 ppm benzene (C<sub>6</sub>H<sub>6</sub>) in N<sub>2</sub> gas. In the clean environment, carbon-induced contact activation did not occur, but the switches exhibited an ECR increase in as little as 100 times less than under cold switching conditions. The degree of erosion increased with <inline-formula> <tex-math notation="LaTeX">$V_{c}$ </tex-math></inline-formula> in both environments. In the contaminated environment, substantial amount of tribopolymer (TP) was generated and contact activation increased as <inline-formula> <tex-math notation="LaTeX">$V_{c}$ </tex-math></inline-formula> increased. For the conditions tested, this work shows that minimizing environmental contamination is the strongest factor in minimizing contact erosion in microswitches, while lowering <inline-formula> <tex-math notation="LaTeX">$V_{c}$ </tex-math></inline-formula> also plays an important role.
The Iron Invariance: Implications for Thermal Convection in Earth's Core

Convection of the liquid iron (Fe) outer core and electrical properties of Fe are responsible for the geodynamo that generates the geomagnetic field. Recent results showed the thermal conductivity of the core and related conductive heat flux may be much larger than previously accepted, suggesting that thermal convection would not be an energy source to power the geodynamo. Here we report experimental measurements of the electrical resistivity of solid and liquid Fe which show invariant values along the melting boundary at pressures up to 24 GPa. The observed resistivity invariance was extrapolated to Earth's predominantly Fe solid inner core and liquid outer core conditions and, using the Wiedemann‐Franz law, the thermal conductivity was calculated. We calculate a conductive core heat flow of 8–9 TW at the core‐mantle boundary. These results provide strong support for thermal convection as a geodynamo energy source.
Artrosis postraumática en pacientes con fractura-luxacion de Lisfranc.

The posttraumatic degenerative osteoarthritis is one of the most frequent complications and more disabling of Lisfranc's fracture - luxation (FLL). Objetive. Evaluate the degree of frequency of posttraumatic degenerative osteoarthritis as complication and adverse effect in patients with Lisfranc's fracture - luxation and value what factors show straight relation or influence in its appearance and development. Material and Method.We have made a transversal prospective and retrospective study of cohorts on 83 patients with diagnosis of Lisfranc's fracture - luxation. We have used a data collecting protocol of items related to the injury, clinical, therapeutic parameters, complications and scales of clinical valuation. The assessment valuation of degenerative osteoarthritis is made under radiological signs realized by means of appearance of radiological signs of Kellgren and Lawrence classification and clinical correlation with presence of pain. Results . The degenerative osteoarthri tis appeared as an influential factor in the results, regular and bad punctuations present major rate of degenerative osteoarthritis (p=0,001), and as for the degree of degenerative osteoarthritis, the most serious cases of degenerative osteoarthritis were placing in the group of bad punctuations (p=0,025). This group of patients presented worse punctuations because they were recounting more pain, major consumption of analgesics, more limitation of the activities of the daily life, of the sports activities and limitation of the travelled distance. Conclusions . The degenerative osteoarthritis appeared as an influential factor in the results (p=0,001). The patients who developed degenerative osteoarthritis were late more time in coming back to his employment or labor previous activity; they had a time more delayed from the surgery to the discharge and major total number of labor disabilities and economic compensations with regard to the patients who did not develop degenerative osteoarthritis, being all these statistically significant values.
Hygroscopic Properties of Saline Mineral Dust From Different Regions in China: Geographical Variations, Compositional Dependence, and Atmospheric Implications

Saline mineral dust particles, emitted from saline topsoil in arid and semiarid regions, contribute significantly to tropospheric aerosol particles. However, hygroscopic properties of saline mineral dust particles, especially for those found in regions other than North America, are poorly understood. In this work we investigated hygroscopic properties of 13 saline mineral dust samples collected from different locations via measuring sample mass change at different relative humidity (RH; up to 90%), and measured their chemical and mineralogical compositions using ion chromatography and X‐ray diffraction. The mass growth factors at 90% RH, defined as the sample mass at 90% RH relative to that at <1% RH, were found to display large geographical variations, spanning from ~1.02 to 6.7, and the corresponding single hygroscopicity parameters (κ) were derived to be in the range of <0.01 to >1.0. The saline components (mainly Na+, Cl−, and SO42−) contained by saline mineral dust particles largely determined their hygroscopicity, and the predicted mass growth factors at 90% RH using an aerosol thermodynamic model (ISORROPIA‐II), agreed with measured values within 20% for most of samples examined, although larger discrepancies also occurred for three samples. Our results improve our understanding in hygroscopicity of saline mineral dust particles and thus their heterogeneous chemistry and ability to serve as cloud condensation nuclei to form cloud droplets.
