Abstract:

Ιn medium voltage cables, the stress control layers play an important part in controlling the electric field distribution around the medium voltage underground cable terminations. Underground cable accessories, used in medium voltage cable systems, need a stress control tube in order to maintain and control the insulation level which is designed for long life times. The term “electrical stress control” refers to the cable termination analysis of optimizing the electrical stress in the area of insulation shield cutback to reduce the electrical field concentration at this point in order to reduc

Abstract:

Aircraft gas turbine components are subjected to severe operating conditions. High temperatures, large thermal strains, and mechanical loads combine to cause the material to undergo significant nonlinear behavior. In order to assure safe, durable components, it is necessary that analysis methods be available to predict the nonlinear deformation. General purpose finite element codes are available to perform elastic and viscoplastic analyses, but the analyses are expensive. Both large plastic and creep strain analyses can require significant computer resources, but typically a plastic solution i

Abstract:

Hypothyroidism is a prevalent thyroid gland disorder where the gland fails to meet the body’s demand for thyroid hormones, specifically triiodothyronine (T3) and thyroxine (T4). Hypothyroidism is categorized into overt (OH) and subclinical (SbH) forms. Overt hypothyroidism is characterized by elevated thyroid-stimulating hormone (TSH) levels and reduced T4 levels, whereas subclinical hypothyroidism presents with elevated TSH levels but normal T4 levels. The objective of this study is to assess the levels of malondialdehyde (MDA) and certain minerals—calcium, magnesium, and phosphor

Abstract:

Extensile fluidic artificial muscles (EFAMs) are soft actuators known for their large ranges of extension, low weight, and blocked forces comparable to those of pneumatic cylinders. EFAMs have yet to be studied in a way that thoroughly focuses on their manufacturing, experimental characterization, and modeling. A fabrication method was developed for production of two EFAMs. The quasi-static axial force response of EFAMs to varying displacement was measured by testing two specimens under isobaric conditions over a pressure range of 103.4–517.1 kPa (15–75 psi) with 103.4 kPa (15 psi) increments.

The damping force of the damper depends upon the shear stress due to fluid viscosity and yield stress induced due to magnetic flux applied. The damping force generated by the damper is calculated.

Abstract:

Oxidative stress is considered to have an important role in the pathogenesis of many inflammatory diseases. This investigation sought to determine whether the appliance of etiologic factors for temporomandibular joint disorder is associated with modified values of oxidative stress as measured by biomarkers in plasma. A case-control study design was used to compare oxidative stress biomarkers (malondialdehyde and glutathione) in plasma from Wistar rats with different etiologic factors (biomechanical stress, estrogen hormones and emotional stress), compared to non-temporomandibular joint control

Abstract:

Thermal damage control of mass concrete is the key to guarantee the quality of mass projects. Based on several engineering experiences and finite element software ANSYS, the temperature field and stress field of the typical dam section of the Tengzigou hydropower station in Sichuan province were simulated. Considering the actual materials used, cooling measures, etc., maximum tensile stress and compressive stress at different time points derived from the temperature stress field during the time of concrete maintenance were calculated, and the numerical results showed that strength increment un

Abstract:

Investigating the mechanism and measures of controlling rockburst in deeply buried underground caverns is a prerequisite for ensuring the safety of personnel, reducing the damage to construction equipment caused by the rockburst, and making the project economical and efficient. Efficient analysis methods for evaluating rockburst control in underground caverns are crucial for qualitatively selecting rockburst control methods and quantifying the effectiveness of rockburst measures. Based on the mechanism of energy accumulation in rock mass and the occurrence of rockburst as well as the active me

Abstract:

This longitudinal study evaluated the mediating role of sense of control during labour in the association between anxiety and depression levels during pregnancy and postpartum posttraumatic stress disorder symptoms. Participants were 57 women. Anxiety and depression were assessed during pregnancy; sense of control and childbirth-related posttraumatic stress disorder symptoms were collected 6–8 weeks after childbirth. Higher levels of anxiety and depression were associated with more postpartum posttraumatic stress disorder symptoms through lack of perceived control. For depression, this happene

Abstract:

The porous structure can reduce the elastic modulus of a dental implant and better approximate the elastic characteristics of the material to the alveolar bone. Therefore, it has the potential to alleviate bone stress shielding around the implant. However, natural bone is heterogeneous, and, thus, introducing a porous structure may produce pathological bone stress. Herein, we designed a porous implant with axial gradient variation in porosity to alleviate stress shielding in the cancellous bone while controlling the peak stress value in the cortical bone margin region.

For sluice concrete structure is more complex due to constrained by the base effect and upper structures, with the purpose of temperature control, we carry out the simulation analysis of temperature and stress during the construction of pier concrete structure. Taking a sluice project as an example, use the method developed by Thermo finite subspace model simulation procedures, the finite element model of pier structure is built with high precision. The results show that the cracking risk is relatively small and prone to surface cracks for baseplate; during construction period, much more atten

Abstract:

Stress is an important factor affecting human behavior, with recent works in the literature distinguishing it as either productive or destructive. The present study investigated how the primary emotion of stress is correlated with engagement, focus, interest, excitement, and relaxation during university students’ examination processes. Given that examinations are highly stressful processes, twenty-six postgraduate students participated in a four-phase experiment (rest, written examination, oral examination, and rest) conducted at the International Hellenic University (IHU) using a modified Tri

Abstract:

Academic stress in students will arise when there is pressure for achievement both in the learning process and the interaction process in school. Academic stress is caused by the inability of students to process perceptions so that the achievement of the learning process is considered as academic demands that exceed the limits of their abilities and also the students' uncertainty about events in their lives can be controlled by themselves. This study aims to determine the relationship of internal locus of control and academic stress of students of SMAN 2 Cimahi. The subject of this research is

Methods: An archival analysis was performed using data from 638 midlife women from the Midlife in the United States II study. Results: Hierarchical linear regression analyses demonstrated that work stress (β = .180, p < .001) and family stress (β = .138, p < .05) significantly predicted using food to cope with stress.
