Motion and force analysis of slow-speed multi-trailer systems
2018
Comparing with the tractor-trailer systems for the road haulage, which must cope with some typical undesired trends, such as high-speed instability, over- or under-steering and off-tracking, the multi-trailer systems for the transport of luggage in the airports or in the railway stations, or for the transfer of goods in the warehouses, run at quite low speeds, but must manage to steer clear of the many obstacles encountered along their path. This type of vehicle is not subject to tire cornering phenomena, because the speed is just low and the wheels are generally stiff. Hence, the vehicle movement is in practice ruled by the non-holonomic rolling constraint of the wheels and by the steerin…
Follow-Up to Ensure Continuity of Care and Support Preventive Care
2023
Over the last decades, the prevalence of chronic health conditions and disabilities among children rose steadily, thanks to medical advances in both treating the primary condition and managing its complications. The improved long-term survival rates led to persistently high rates of pediatric chronic health conditions, which are often burdened with limitation in daily activity and dependence on medication, special diets, medical technology, assistive devices, and specialized staff. Therefore, children with complex chronic conditions are a frail population who generally need healthcare services beyond what is usual for healthy children. Indeed, their health issues often require specialized a…
Frailty and Cardiovascular Diseases: Research into an Elderly Population
2020
This book aims to clarify the potential association between frailty and cardiovascular disease in older people. Covering the biological as well as the clinical point of view, it allows researchers and clinicians to discover the significance of this topic. The contributions cover the most important aspects in the potential relationship between frailty and cardiovascular disease. In particular, authoritative authors in this field have clarified the definition and the epidemiology of frailty and cardiovascular disease in older people. A large part of the volume is dedicated to the biological mechanisms of frailty and cardiovascular disease, trying to find those in common between these two cond…
Frailty and oral health-related quality of life in community-dwelling older adults: a cross-sectional study
2021
Abstract Poor oral health has been associated with frailty among older adults. However, limited evidence has been available on whether frailty can affect oral health-related quality of life (OHRQoL) in older adults. This study aimed to investigate the relationship between frailty and OHRQoL among community-dwelling older adults. A household-based cross-sectional study involving community-dwelling older adults aged 65 years and older was conducted in the city of Bauru, Brazil. Data on frailty status, sociodemographic characteristics, self-perceived dental care needs, and OHRQoL (OHIP-14) were collected through individual interviews. The use of and the need for total dental prostheses were as…
The Mediating Effect of Different Exercise Programs on the Immune Profile of Frail Older Women with Cognitive Impairment.
2020
Background: Frail individuals experience an accelerated immunosenescence, and exercise has been identified as a therapy to promote a better inflammatory environment. Objective: To analyze the effects of 28-weeks of two different exercise protocols on the functional fitness and immune profiles of institutionalized pre-frail and frail women with mild cognitive impairment. Methods: Participants residing in care homes (n=60, 81±7.84 years old) were randomized into three groups: a chair elastic band muscle-strength exercise (CSE, n=21; 81±4.79), a chair multimodal exercise (CME, n=20; 80±8.19), and a control non-exercise (CGne, n=19; 80±10.01). Both CME and CSE groups performed progressive circ…
optomotor-blind suppresses instability at the A/P compartment boundary of the Drosophila wing.
2008
Formation and function of the A/P compartment boundary of the Drosophila wing have been studied intensely. The boundary prevents mingling of A and P cells, is characterized by an expression discontinuity of several genes like engrailed, Cubitus interruptus, hedgehog and decapentaplegic and is essential for patterning the wing. Compared with segmental or compartmental boundaries in several other systems which generally manifest as folds or clefts, the wing A/P boundary is morphologically inconspicuous in both the larval and adult stage. We show here that the Drosophila wing A/P boundary, too, is susceptible to fold and cleft formation and that these processes are suppressed by the T-box tran…
The influence of transport offer on passenger traffic in the railway transport system in a post-socialist country : case study of Poland
2021
Abstract The study examines factors influencing the number of rail passengers in Poland. The subjects of observation were 62 cities with poviat rights. The main factors influencing demand are the number of connections and the speed of trains. Therefore, we developed an original indicator – weighted number of connections, which takes into account the number of rail connections and the speed of trains. The article can be divided into two main parts: an assessment of the diversification of transport offer and transport demand in spatial terms, and an evaluation of the relationship between the variables. Poland has a large spatial diversity in terms of public rail transport offer and passenger …
Special track on Geometric Constraints and Reasoning
2008
Geometric Computing and Reasoning (GCR) aims at emphasizing recent trends in the domain of geometric constraint solving and automated, or computer aided deduction in geometry. This year sees the third edition of this technical track of SAC.
Gerontology is essential to the identity of geriatric medicine
2019
The concept of the preeminence of multidimensional func-tional status in health care, one of the first achievements of geriatric medicine, has been endorsed by diverse sources, and is now a cultural patrimony of medicine. One of the main goals of geriatric medicine is to allow older people to remain as independent as possible for as long as possible. The integrated research of geriatricians and gerontologists has been at the forefront of the development, testing, and application of tools to assess functional status, including activities of daily living, gait and mobility, cognition, psy-chological status, depression, and social support.
