Purveyors are concerned about the potential food safety risk of nonintact meat products and are seeking strategies to ensure adequate meat tenderness without blade tenderization. This study was conducted to determine the effects of blade tenderization and time and temperature of aging on beef longissimus lumborum (LL) and gluteus medius (GM) tenderness. Beef strip loins (n = 300) and top sirloi...

We present time-dependent dielectric loss data for various glass formers below the glass temperature. The observed aging dynamics is described using a modified Kohlrausch-Williams-Watts law taking into account the variation of the relaxation time during aging. It leads to values for the aging relaxation time and stretching exponent, fully consistent with the results from equilibrium measurement...

Aging can be defined as progressive functional decline and increasing mortality over time. Here, we review evidence linking aging to nuclear DNA lesions: DNA damage accumulates with age, and DNA repair defects can cause phenotypes resembling premature aging. We discuss how cellular DNA damage responses may contribute to manifestations of aging. We review Sir2, a factor linking genomic stability...

Al-Zn-Mg alloys with different precipitate sizes were investigated to determine the influence of size on flow stress and dislocation density change during tensile deformation. The was measured using in-situ X-ray diffraction at SPring-8 synchrotron radiation facility a time resolution about 2 s. In region II rapid multiplication, from under-aging peak aging, increased increasing aging time. Und...

This paper investigates the morphology, thermal, and electrical properties of LDPE (low-density polyethylene)-based nanocomposites after thermal aging. The FTIR (Fourier transform infrared spectroscopy) spectra results show that thermo-oxidative reactions occur in neat LDPE and LDPE/SiO₂ nanocomposites when the aging time is 35 days and in LDPE/MgO nanocomposites when the aging time is 77 days....

Japan has been aging faster than other industrialized nations, and its experience offers useful lessons to others. Japan has been willing to expand its welfare state with a long-term care (LTC) insurance to finance home care and nursing home care for frail elderly. As Ikegami shows, it created new facilities and expanded specialized staffing for home care, developed a c...

high variability in delivering the target torque is reported for friction-style mechanical torque limiting devices (f-s mtlds). the effect of aging (number of use) on the accuracy of these devices is not clear. the purpose of this study was to assess the effect of aging on the accuracy (±10% of the target torque) of f-s mtlds.fifteen new f-s mtlds and their appropriate drivers from three differ...

introduction: decrease in sleep quality is an age-related problem which appears in different features such as difficulty in sleeping, over sleeping and unusual behaviors during sleep. regarding the importance of sleep quality among older adults and also its effects on their quality of life and physical and mental status, the study was conducted to determine the status and quality of sleep in ol...

Nanocrystalline ceria has been considered as support for carbon monoxide preferentially oxidation. In this study ceria was prepared by precipitation method and the effects of preparation conditions, such as pH of solution (8-10), aging time (1-12 hr), drying temperature (80-120 °C), calcination time (2-6 hr) and temperature (400-600 °C) were investigated on ceria synthesized powders properties....
