Magnetic Barkhausen noise (MBN) technology is widely used to reveal the microscopic mechanism of magnetomechanical phenomena, but morphological transition induced by tension has not yet been confirmed experimental measurements. Here, we report a novel effect on morphology MBN signals due tensile stress with pre-introduced strain. We present power-law relation between critical for and degree str...
The purpose of this study was to identify the key factors involved in patulin adsorption by heat-inactivated lactic acid bacteria (LAB) cells. For preventing bacterial contamination, a sterilization process was involved in the adsorption process. The effects of various physical, chemical, and enzymatic pre-treatments, simultaneous treatments, and post-treatments on the patulin adsorption perfor...
Anchorage performance of a high-pressure pre-tightening resin anchor with a compressed grouting body
Supports for deep mine roadways located in soft surrounding rock face several problems: difficulty in applying pre-tightening force, low bearing capacity, and poor initial support. To solve these problems, this study proposes a high-pressure pre-tightening resin anchor with a compressed grouting body for use in soft and fractured rock surrounding a deep roadway. Using model experiments, we anal...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Transient reductions in myocardial strain coupled with cardiac-specific biomarker release have been reported after prolonged exercise (>180 min). However, it is unknown if 1) shorter-duration exercise (60 min) can perturb cardiac function or 2) if exercise-induced reductions in strain are masked by hemodynamic changes that are associated with passive recovery from exercise. Left ventricular (LV...
Introduction: Cancer is one of the most common diseases in the world. Due to the carcinogenic combinations of drug, there is a risk of mutagenic substances in consumers. The aim of this study was to investigate the mutagenicity of opium by the Ames test. Methods: Firstly, the purity of the Salmonella typhimurium strain TA100 was confirmed in terms of purity of mutagenic properties. Then, sampl...
Pre-clinical animal models are important to study the fundamental biological and functional mechanisms involved in the longitudinal evolution of heart failure (HF). Particularly, large animal models, like nonhuman primates (NHPs), that possess greater physiological, biochemical, and phylogenetic similarity to humans are gaining interest. To assess the translatability of these models into human ...
