On one side, there is the ever-increasing awareness of the adverse effects that noise and lack of acoustic comfort may have on human health. On the other, the availability of more sophisticated fabrication techniques, calculation methods, and new materials, has stimulated researchers and, more and more frequently, industry to develop customized materials with improved properties.This book collects contributions from different researchers covering several topics. A group of papers investigated the use of 3D printing to obtain perforated panels with extended frequency response, as well as to ideally design an optimized cell distribution to print (when fabrication techniques will make it possible) a porous material with a broader sound absorption. The role of the geometrical and microstructural properties of granular molecular sieves is investigated by another paper. A second group of papers focused its attention on the use of natural or recycled components to create a skeleton of porous materials with good sound-absorbing properties and low environmental impact. Cigarette butts, recycled textile waste, and almond skins have been investigated by different authors.Finally, the last batch of papers included a review of sound insulation properties of innovative concretes and two research papers focussing on a numerical and experimental analysis of wood plastic composite (WPC) panels and on the potential of semi-active solutions employing compressible constrained layer damping (CCLD). 606 $aTechnology: general issues$2bicssc 610 $aabsorber array 610 $aacoustic properties 610 $aagro-waste 610 $aanisotropic materials 610 $abiopolymers 610 $acigarette butts 610 $acircular economy 610 $acomposite materials 610 $acompressible constrained layer damping 610 $aconcrete 610 $adiffuse field 610 $aflame retardant 610 $agraded properties 610 $ahygrothermal performances 610 $aimpedance tube 610 $alow frequency absorption 610 $amolecular sieve pellets 610 $amorphing structure 610 $an/a 610 $anoise 610 $aoptimized absorption 610 $aorthotropic panel 610 $aperforated panel 610 $aperforated plates with extended tubes 610 $aperiodic absorber 610 $aphase change material 610 $apolyurethane foam 610 $aporous materials 610 $aradiation efficiency 610 $arecycling 610 $asandwich panel 610 $asemi-active damping 610 $asound absorber 610 $asound absorption 610 $asound transmission loss 610 $asound-absorbing 610 $asound-reflecting 610 $asustainable material 610 $asustainable materials 610 $atextile waste 610 $athermal property 610 $atransmission loss 610 $avariability analysis 610 $awavenumber analysis 610 $awood plastic composite 615 7$aTechnology: general issues 700 $aMartellotta$b Francesco$4edt$01295449 702 $aMartellotta$b Francesco$4oth 906 $aBOOK 912 $a9910557370903321 996 $aInnovative Composite Materials for Sound Absorption and Insulation$93023458 997 $aUNINA LEADER 06293nam 2201717z- 450 001 9910585944703321 005 20220812 035 $a(CKB)5600000000483031 035 $a(oapen)https://directory.doabooks.org/handle/20.500.12854/91182 035 $a(oapen)doab91182 035 $a(EXLCZ)995600000000483031 100 $a20202208d2022 |y 0 101 0 $aeng 135 $aurmn|---annan 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aLow Back Pain (LBP) 210 $aBasel$cMDPI - Multidisciplinary Digital Publishing Institute$d2022 215 $a1 online resource (318 p.) 311 08$a3-0365-4455-0 311 08$a3-0365-4456-9 330 $aLow back pain (LBP) is a major public health problem, being the most commonly reported musculoskeletal disorder (MSD) and the leading cause of compromised quality of life and work absenteeism. Indeed, LBP is the leading worldwide cause of years lost to disability, and its burden is growing alongside the increasing and aging population. The etiology, pathogenesis, and occupational risk factors of LBP are still not fully understood. It is crucial to give a stronger focus to reducing the consequences of LBP, as well as preventing its onset. Primary prevention at the occupational level remains important for highly exposed groups. Therefore, it is essential to identify which treatment options and workplace-based intervention strategies are effective in increasing participation at work and encouraging early return-to-work to reduce the consequences of LBP. The present Special Issue offers a unique opportunity to update many of the recent advances and perspectives of this health problem. A number of topics will be covered in order to attract high-quality research papers, including the following major areas: prevalence and epidemiological data, etiology, prevention, assessment and treatment approaches, and health promotion strategies for LBP. We have received a wide range of submissions, including research on the physical, psychosocial, environmental, and occupational perspectives, also focused on workplace interventions. 517 $aLow Back Pain 606 $aEnvironmental science, engineering and technology$2bicssc 606 $aTechnology: general issues$2bicssc 610 $aabsenteeism 610 $aAfrican American 610 $aanthropometry 610 $aartificial intelligence 610 $aAustralian method 610 $aback pain 610 $aback problems 610 $abone cancer 610 $abone metastasis 610 $acanal stenosis 610 $achronic 610 $acognitive behavioral therapy 610 $acomputer aided diagnosis 610 $acomputer vision 610 $acore stability 610 $across-sectional studies 610 $aCT 610 $adecision support systems 610 $adeep learning 610 $adepression 610 $adigital image processing 610 $adisability 610 $adisk herniation 610 $aEMG 610 $aepidemiology 610 $aepidural steroid injections 610 $aergonomics 610 $afear of pain 610 $afear-avoidance beliefs 610 $agender difference 610 $aGoogle Trends 610 $ahandling task 610 $ahip-knee line 610 $ainfodemiology 610 $ainsurance 610 $akinesiophobia 610 $aknowledge 610 $aLatino 610 $alow back pain 610 $alow back pain (LBP) 610 $aLow Back Pain Scale 610 $alow-back pain 610 $alower extremity 610 $alumbalgia 610 $alumbar decompression 610 $alumbar fusion 610 $alumbar instability 610 $alumbar rotation 610 $alumbar translation 610 $alumbosacral radicular pain 610 $alung cancer 610 $amachine learning 610 $amanual therapy 610 $amaximum voluntary isometric contraction 610 $ameta-analysis 610 $amindfulness-based stress reduction 610 $aMRI 610 $amusculoskeletal disorders 610 $amusculoskeletal pain 610 $aNeurac 610 $anon-radiological lumbar instability 610 $aoccupational back-support exoskeleton 610 $aoccupational disorder 610 $aoccupational health 610 $aoccupational safety and health 610 $aolder adults 610 $aorthopaedics 610 $apain 610 $apatient care 610 $apelvic incidence 610 $aphysical activity 610 $apopulation attributable fraction 610 $apostural stability 610 $aprevention 610 $aprostate cancer 610 $apublic health 610 $aradiography 610 $aradiomics 610 $arehabilitation nurses 610 $areliability 610 $areturn to work 610 $areview 610 $arisk assessment 610 $aROC curve 610 $asatisfaction 610 $ascreening tool 610 $aseasonality 610 $asedentary behaviour 610 $asensitivity 610 $asignature 610 $aspecificity 610 $aspinal load 610 $astanding position 610 $asub-threshold lumbar instability 610 $asystematic review 610 $aunderserved 610 $aunemployment 610 $aunexpected external postural perturbations 610 $awearable assistive device 610 $aWikipedia 610 $awork ability 610 $aworkers 610 $aworkload 610 $aworkplace 610 $aworkplace interventions 610 $aX-ray 615 7$aEnvironmental science, engineering and technology 615 7$aTechnology: general issues 700 $aDenaro$b Vincenzo$4edt$01293868 702 $aIavicoli$b Sergio$4edt 702 $aRusso$b Fabrizio$4edt 702 $aVadalà$b Gianluca$4edt 702 $aDenaro$b Vincenzo$4oth 702 $aIavicoli$b Sergio$4oth 702 $aRusso$b Fabrizio$4oth 702 $aVadalà$b Gianluca$4oth 906 $aBOOK 912 $a9910585944703321 996 $aLow Back Pain (LBP)$93022801 997 $aUNINA
