Mangroves migrate northward in Florida and colonize marshes historically dominated by salt marsh species. In theory, this migration should be facilitated by greater numbers of propagules stemming from increased reproductive activity and greater genetic variability caused by outcrossing. We aimed to determine if stand reproduction and % outcrossing were affected by cold stress (stress increases ...

Poultry welfare is closely related to human health and animal production which a sensitive process. While several statistical methods are available measure observed variables (stocking density), unobserved (latent) such as emotional, psychological situations typically analyzed using factor analysis. In recent years, structural equation modeling (SEM) has been used effectively in many fields agr...

In this study, thermal simulation experiments under different austenitization temperatures and different stress states were conducted. High-temperature laser scanning confocal microscopy (LSCM), thermal dilatometry, and scanning electron microscope (SEM) were used to quantitatively investigate the effects of the uniaxial compressive stress on bainitic transformation at 330 ̋C following differen...

The two main components of the stress system are the hypothalamic-pituitary-adrenal (HPA) and sympathetic-adrenal-medullary (SAM) axes. While cortisol has been commonly used as a biomarker of HPA functioning, much less attention has been paid to the role of the SAM in this context. Studies have shown that long-term breast cancer survivors display abnormal reactive cortisol patterns, suggesting ...

Adipose tissue is highly specialized to store lipid and/or release energy from lipid stores in response to a variety of signals. Adipose remodeling is the critical physiological process which involves lipogenesis and lipolysis to exhibit energy homeostasis. Recently, interest in the study of fish adipocytes has burgeoned due to the rising incidence of polluted environment. Determination of chan...

Rheological and microstructural changes that occurred in ropy yogurt during shearing were ob served. Yogurt made with an exopolymer-producing (ropy) strain of Lactobacillus delbrueckii subsp. bulgaricfui and non ropy s tram of Streptococcus thermop us was subjected to an increas1ng shear rate from 0-833 s 1 using a Haake Rotavisco RV2. Shear stress noticeably increased to a peak value and then ...

AIM To determine how instrument design affects the fatigue life of two nickel-titanium (Ni-Ti) rotary systems (Mtwo and ProTaper) under cyclic fatigue stress in simulated root canals. METHODOLOGY Cyclic fatigue testing of instruments was performed in stainless steel artificial canals with radii of curvature of 2 or 5 mm and an angle of curvature of 60 degrees . A total of 260 instruments were...
