Relationship between occupational and leisure-time physical activity and the need for recovery after work
2023
Abstract Background Health benefits of physical activity are very well acknowledged but the role of both occupational physical activity (OPA) and leisure time physical activity (LTPA) in recovery after work is not thoroughly understood. The purpose of this study was to investigate the association between accelerometer-measured OPA and LTPA and the need for recovery after work (NFR) in early childhood education and care (ECEC) professionals. Methods The study participants were 217 female ECEC professionals aged 17–64. Physical activity was recorded with a three-axis accelerometer (ActiGraph GT9X Link, ActiGraph, USA) for seven consecutive days. Separate analyses were conducted for both OPA a…
Active and passive recovery influence responses of luteinizing hormone and testosterone to a fatiguing strength loading
2018
The purpose of this study was to examine the acute hormonal and muscular responses to a strenuous strength loading [bilateral leg press (LP) 10x10 1RM] followed by loading-specific active (AR, n = 7, LP 10x10x30% 1RM) or passive (PR, n = 11, seated) recovery. The subjects were men age: 26±4 years, height: 174±8 cm, body mass: 75±13 kg. After control measurements, experimental measurements were conducted at pre and post loading as well as post recovery and next morning. A significantly higher absolute concentration (p<0.05) of serum luteinizing hormone (LH) was observed in AR than PR at next morning while no differences were observed in serum testosterone (T), cortisol (C) or sex hormone bin…
Searching for a robust strategy for minimizing alkali chlorides in fluidized bed boilers during burning of high SRF-energy-share fuel
2015
Abstract To meet the increasing volume of waste to be treated via energy recovery, high SRF-energy-share fuel is being fired in conventional waste-to-energy facilities. In this work, corrosion related risk during firing of 70 e-% share (target fuel) is studied and compared against the base case fuel containing 50 e-% share. Cl and S concentration is highest in the target fuel as a direct result of increasing the proportion of SRF in the fuel mixture. Br, Zn and Pb showed the same trend. Meanwhile, the concentration of Na, K, Al and Si are highly dependent on the type of the SRF fired. The corrosion risk of the base and target fuels are analyzed using the composition of the fine aerosol frac…
ARCHITETTURA E COSCIENZA TECNOLOGICA : LA COSTRUIBILITÀ DEL PROGETTO - UN DIBATTITO APERTO
2004
Il principio di centralità della tecnologia, nel rapporto tra progetto e costruzione, scaturisce da una lunga trattatistica sul significato della tecnica e del suo rapporto con le arti, i mestierie l’architettura a partire dagli antichi greci e romani. La tecnologia come arte del costruire ha origine classica, Vitruvio è senz’altro il più citato tra gli illustri latini.. Il dibattito umanistico-scientifico assume un ruolo di rilievo nell’Università tedesca alla fine del ‘700 in Germania, dove la tecnologia dell’architettura viene introdotta come disciplina autonoma. Johann Beckmann1 (1739-1811), uno dei padri della tecnologia nascente, la definiva come la disciplina che studia le trasformaz…
THE "TECHNOLOGICAL PARAMETERS" OF HERITAGE CONSERVATION: FACTORS OF DECAY-INSTRUMENTS OF BUILDING RECOVERY AND PREVENTION MEASURES
2006
This is the age of the “global knowledge”, of the “local inadequacies”, of the specialist enterprises and of the managerial difficulties to limit the risk both material (structural decay/ physical obsolescence / security needs / static disease) and cultural and environmental (function degradations – inattentive environmental conditions) of the discontinuity between the past and the present and to realize the right living conditions and protection of heritage conservation, it is necessary to create new perspectives “to continue to make history consciousness”. The new instruments of the recovery and maintenance of the extant as well as the new strategies of equilibrium and protection for the …
ILLEGAL CONSTRUCTIONS IN COASTAL AREAS. PALERMO’S SEASIDE
2012
Strategies to qualify coastal settings must be focused on the evaluation of seaside even in terms of sustainable tourism increasing. Projecting and operating to realize these aims means: to stimulate an eco-compatible behaviour even through new law instruments aimed to reach quality standards, to activate an ecological net of receptive structures, to realize suistable instruments to periodically monitor places the control the environmental impact. In this way, the present study analyzes the problems of Palermo’s seaside, attacked by urbanization and wild speculation, expressing on the forecast of urban plans and on eco-compatible usage strategies
EVOLUTION OF BUILDING SISTEMS AND BUILDING PATOLOGIES: VARIABLES OF INTERACTION
2006
This paper describes the "variables of interaction" between architecture-materials-techiques and the problems inherent in building recovery. Programming the building recovery for the development of guidelines for the 21ts century construction must take into consideration the complex correlation between technologies and related building pathologies.
Non-structural proteins P17 and P33 are involved in the assembly of the internal membrane-containing virus PRD1.
2015
AbstractBacteriophage PRD1, which has been studied intensively at the structural and functional levels, still has some gene products with unknown functions and certain aspects of the PRD1 assembly process have remained unsolved. In this study, we demonstrate that the phage-encoded non-structural proteins P17 and P33, either individually or together, complement the defect in a temperature-sensitive GroES mutant of Escherichia coli for host growth and PRD1 propagation. Confocal microscopy of fluorescent fusion proteins revealed co-localisation between P33 and P17 as well as between P33 and the host chaperonin GroEL. A fluorescence recovery after photobleaching assay demonstrated that the diff…
Mechanisms of adaptation from a multiple to a single step recovery strategy following repeated exposure to forward loss of balance in older adults
2012
When released from an initial, static, forward lean angle and instructed to recover with a single step, some older adults are able to meet the task requirements, whereas others either stumble or fall. The purpose of the present study was to use the concept of margin of stability (MoS) to investigate balance recovery responses in the anterior-posterior direction exhibited by older single steppers, multiple steppers and those that are able to adapt from multiple to single steps following exposure to repeated forward loss of balance. One hundred and fifty-one healthy, community dwelling, older adults, aged 65–80 years, participated in the study. Participants performed four trials of the balanc…
Analysis of particles size distributions in Mg(OH)2 precipitation from highly concentrated MgCl2 solutions
2022
Magnesium is a raw material of great importance, which attracted increasing interest in the last years. A promising route is to recover magnesium in the form of Magnesium Hydroxide via precipitation from highly concentrated Mg2+ resources, e.g. industrial or natural brines and bitterns. Several production methods and characterization procedures have been presented in the literature reporting a broad variety of Mg(OH)2 particle sizes. In the present work, a detailed experimental investigation is aiming to shed light on the characteristics of produced Mg(OH)2 particles and their dependence upon the reacting conditions. To this purpose, two T-shaped mixers were employed to tune and control the…
