Human reliability analysis in maintenance and repair operations of mining trucks: A Bayesian network approach.

Failures in mining machinery can abruptly halt mineral production and operations, emphasizing the indispensable role of humans in maintenance and repair operations. Addressing human errors is crucial for ensuring a safe and reliable system, particularly during maintenance activities where accidents frequently occur. This paper focuses on evaluating Human Reliability (HR) to enhance activity implementation effectiveness.

The effect of mindfulness-based stress reduction (MBSR) training on serum cortisol levels, depression, stress, and anxiety in type 2 diabetic older adults during the COVID-19 outbreak.

Old age is rapidly increasing and is linked to with chronic diseases, especially diabetes. Diabetes is associated with increased anxiety, stress, and depression and, in turn, can increase cortisol secretion. To this end, the present research studied the impact of mindfulness-based stress reduction (MBSR) training on serum cortisol levels, depression, anxiety, and stress in type 2 diabetic (T2DM) older adults during the COVID-19 epidemic.

The Effects of Kinesio Tape on Low Back Pain and Disability in Pregnant Women.

Background: Low Back Pain (LBP) is one of the most common complaints during pregnancy, which could cause performance disability. Kinesio tape is a drug-free elastic therapeutic cotton tape used in treating musculoskeletal problems. This study aims to determine the effects of Kinesio tape on LBP and disability in pregnant women.

Improved mine waste dump planning through integration of geochemical and mineralogical data and mixed integer programming: Reducing acid rock generation from mine waste.

Although the environmental significance of acid rock drainage (ARD) generated from mining wastes is well known, selecting the appropriate ARD management strategy can prove a complicated task. Chemical methods are favored for initial mine waste characterization but using these exclusively can overlook key factors, e.g.

The effect of aromatherapy with lavender essential oil on the working memory of women with multiple sclerosis.

Working memory, one of the cognitive components, may be impaired in patients with multiple sclerosis. Accordingly, this study aims to determine the effects of aromatherapy with lavender essential oil on the working memory of women with multiple sclerosis (MS). In this clinical trial, 60 women with multiple sclerosis were selected using the sampling method from patients referred to the MS Clinic of Rafsanjan.

Effect of educational intervention on preventive behaviors of brucellosis among health volunteers in Rafsanjan city: Application of health belief model.

Background: Human brucellosis can be a source of problems that affect public health, social, and economic well-being of the world's population. This study was conducted with the aim of determining the effect of Educational Intervention (EI) based on Health Belief Model (HBM) on preventive behaviors against brucellosis in Health Volunteers (HVs) in Rafsanjan.

Materials And Methods: Randomly, 104 HVs, in the intervention and control group, participated in a quasi-randomized, controlled experimental study.

Development of a MIP model to maximize NPV and minimize adverse environmental impact-a heuristic approach.

Block sequencing is of great importance in an open-pit mining operation. Sequencing is usually performed to maximize the net present value (NPV). Also, from the environmental viewpoint, the sequence of dumping mined materials is of significant value in the sulfide mines.

Jugular venous reflux may mimic type I dural arterio-venous fistula on arterial spin labeling magnetic resonance images.

Purpose: Previous studies have shown that arterial spin-labeling (ASL) has high sensitivity and specificity for detecting dural arteriovenous fistulas (DAVFs). However, in case of jugular venous reflux (JVR), the labeled protons in the jugular vein may lead to a venous hypersignal in the jugular vein, sigmoid, and transverse sinus on ASL images and mimic DAVF.

Methods: To ascertain this hypothesis, two blinded senior neuroradiologists independently and retrospectively reviewed randomized ASL images and graded the likelihood of DAVF on a 5-point Likert scale in 2 groups of patients: (i) 13 patients with angiographically proven type I DAVF; and (ii) 11 patients with typical JVR diagnosed on the basis of clinical and MR imaging data, first using ASL alone, and second using ASL together with all of the sequences including 4D CE MRA.

Indole itself and its novel derivative affect PML cells proliferation via controlling the expression of cell cycle genes.

Recently the role of indole and pyran rings in carcinogenesis has been well studied. Here we studied the effects and the possible mechanisms of the action of basal indole (I3A) and its novel indole derivative (C19H15F3N2O) on inhibition of proliferation cells in acute promyelocytic leukemia NB4 cell line by examining the expression of cell cycle genes. We treated NB4 cells with concentration of C19H15F3N2O for 24-72 h.

Evaluating of OCT-4 and NANOG was differentially regulated by a new derivative indole in leukemia cell line.

Background: The potential exists to improve treatment through characterization of tumor stem cells and identification of therapeutic targets Using OCT-4 and NANOG genes. Here we have synthesized and investigated the potential of; New Indole-3-carbaldehyde derivative (NI-3-CD) in inhibiting the expression of self-renewal regulatory factors and cancer stem cell gene in a leukemia cell line NB4.

Methodology: The NB4 cells were cultured in RPMI1640 medium contained NI-3-CD and I3F (15.

Opium addiction as an independent risk factor for coronary microvascular dysfunction: A case-control study of 250 consecutive patients with slow-flow angina.

Background: Approximately 20% to 30% of patients who undergo coronary angiography for assessment of typical cardiac chest pain display microvascular coronary dysfunction (MCD). This study aimed to determine potential relationships between baseline clinical characteristics and likelihood of MCD diagnosis in a large group of patients with stable angina symptoms, positive exercise test and angiographic ally normal epicardial coronary arteries.
