VirEthics and the Problem of Aging
… those normal changes that distinguish natural aging and dying processes from external forces which truly do impede life. I argue in this paper that several versions of contemporary virethics, which depend heavily on a theory of the good life, suffer from this very defect. I examine the …

Deficits in inhibitory function mediate age-related multisensory and postural function decline
The natural aging process can result in deficits across sensory and motor systems, leading to difficulty in navigating the environment at both a physical and perceptual level. For instance, degraded vision and hearing can result in unreliable sensory information and difficulty in comprehending …

Fault Location in High Voltage Shunt Capacitor Banks
… capacitance change due to temperature effects or natural aging. The presented fault location methods are further enhanced to detect the number of failed elements. The proposed methods can be integrated into common unbalance protection of the multi-functional numerical SCB relays and put forth …

Experimental Damage Diagnosis of a Model Three-Story Spatial Frame
… from short-term abnormal stresses to long-term natural aging. Detection of changes in a structure's ability to withstand subsequent loads can aid decisions on safety, repair, rehabilitation, and demolition. Dynamic property shifts can show internal cracks and minor damage before propagation or …

Exploring Beta Cell NADPH production using Organelle-targeted Apollo-NADP+ Sensors
… by cellular senescence associated with natural aging. Senescence impacts mitochondrial-dependent pyruvate cycling and nicotinamide nucleotide transhydrogenase (NNT) activity, which are important for production of beta cell NADPH to support biomolecule synthesis during cell growth and for …

Nampt-Mediated Nad+ Homeostasis in Skeletal Muscle: Implications for Healthy Aging
… carbohydrate and lipid fuels. The course of natural aging leads to a gradual decline in the mass, strength, and oxidative capacity of skeletal muscle, which increases the susceptibility of the elderly to frailty and metabolic diseases, such as Type II Diabetes. Ectopic muscle lipids can also …

Crash Analysis of Degraded Concrete Containment Structures
… of dry cask structures will degrade due to the natural aging and the environmental effect shrinkage, creep, heat transfer, moisture diffusion, and Alkali-Silica Reaction (ASR). Long-term creep and shrinkage of vertical dry cask are modeled using the B4 creep formulation for concrete. The results …

Mitochondria and Fatty Acid Homeostasis in the Aging Nervous System
… are among the most salient outcomes of the natural aging process. Particularly among humans who have experienced dramatic increases in lifespan over the last century, age-associated cognitive decline has become especially problematic in our increasingly elderly population. To mitigate the …

Acquired Hearing Impairment in Older Couple Relationships: an Exploration of Couple Resilience Processes
Adults may acquire a hearing impairment through natural aging processes (presbycusis), exposure to loud noises, illnesses (e.g., Meniere's disease), and hereditary factors. Because hearing loss affects basic communication processes, couples often have to adjust their ways of interacting when one …

An automatic method for inspecting plywood shear samples
… samples with various treatments to simulate natural aging, 3) shearing each sample into two halves, and 4) estimating the percent wood failure (as opposed to glue failure) produced by the shear by visually inspecting these sample halves. A region of solid wood or a region of wood fibers …

Age related memory loss and the role of the ubiquitin proteasome system
… transformations are an inevitable aspect of the natural aging process, occurring in individuals regardless of the presence of neurodegenerative diseases or neurological injuries. At the molecular level, the aging brain encounters challenges, such as the accumulation of damaged proteins. The …

A Socio-History and Genealogy of Dementia Thought and Conceptualisation in Western Society
… disorder (such as neuro-psychiatric, part of the natural aging process, cognitive, and so on) are important in understanding how it has come to be problematized. The manner by which this has been framed has implications not only for the perceived disciplinary ownership of dementia, but also for …

The Gut Microbiome as a Novel Approach for Reversing Long-Term Inflammation and Accelerated Aging Across the Lifespan
… but its ramifications, including accelerated aging, are poorly understood. As this coincides with critical stages of brain development, interventions started months or years post-injury may still improve survivors’ quality of life. One promising intervention is to manipulate the gut …

Analysis and Modeling of Landscape Topography: Statistical Description and Evolution Under Natural and Disturbed Conditions
… across various spatial scales. Furthermore, the natural evolution of a topography under the influence of geologic erosion can be greatly altered by anthropogenic disturbances (e.g., through agriculture, mining, deforestation), with the potential of accelerating soil erosion, causing land …

Determination of the Shelf Life of Aluminum Electrolytic Capacitors.
… examined the electrical characteristics of naturally aged capacitors of several different styles to determine if design parameters were still within limits. Additionally, the effectiveness of a technique known as “Reforming” was examined to determine its impact on those characteristics.

Cardiac magnetic resonance imaging for non-invasive detection of myocardial fibrosis
… of collagen-breakdown and deposition-in heart naturally occurs, maintain its structure and contractile function. However, when deposition exceeds breakdown, it inevitably leads to excess myocardial fibrosis, resulting in stiffness and thickening of the heart muscle, leading ultimately to …

Menopausa em (re)vista : os discursos praticados pela Revista Maria em torno da menopausa (1978-1988)
… versus aceitação do processo de envelhecimento natural e activo de qualquer ser humano (Bee, 1997; OMS, 1996). A esta construção social não está alheio o papel dos media que, como agentes socializadores e de divulgação em massa, reforçam os estereótipos e preconceitos e pouco divulgam acerca da …
