Physical fitness profile in female horseback riders.
2019
BACKGROUND: The purpose of the present study was to examine the levels of endurance and neuromuscular performance variables in female horseback riders. METHODS: 52 female Finnish riders were involved (age 29.4±8.9 yrs, height 1.68±0.06 m, weight 67.5±10.0 kg), 19 show-jumping riders (SJ) and 33 eventing riders (E), riding-time minimum of 4 times/week, jumping level of minimum 1.06±0.11m. The measurements were maximal bilateral isometric leg press force (MVCLP), maximal unilateral isometric knee extension (MVCKE) and flexion forces (MVCKF), countermovement jump (CMJ), maximal isometric force of the trunk extensor and flexor muscles (MVCE, MVCF), weight distribution of the body (WD), handgrip…
Experts' assessment of probability and level of pesticide exposure in agricultural workers.
2000
The occupational history of the parents of 261 infants with congenital malformations and 261 matched controls was collected. During the relevant time period before the birth of their child, 183 parents were involved in agricultural activities, 49% of them having directly applied pesticides. Two experts assessed the probability and the level of exposure to each quoted pesticide (582 observations) by using 4-point scales. Interrater agreement was estimated. Kappa-weighted values for probability and level of exposure were, respectively, kappa = 0.36 and kappa = 0.39. In the analysis of some categories of exposure (non-applicators, herbicides) very low interrater agreement was observed. In epid…
Internet-delivered Cognitive-Behavioral Therapy (iCBT) for Adults with Prolonged Grief Disorder (PGD): A Study Protocol for a Randomized Feasibility …
2021
IntroductionGrief is an emotional reaction to the loss of a loved one with a natural recovery. Approximately 10% of people who lose a loved one develop prolonged grief disorder (PGD). Internet-based and computer-based interventions (ie, internet-delivered cognitive–behavioural therapy, iCBT) are a cost-effective alternative that makes it possible to reach more people with PGD. The main aim of this study is to assess the feasibility of a new iCBT—called GROw—for PGD. As a secondary objective, the potential effectiveness of GROw will be explored.Methods and analysisThis study is a two-arm feasibility randomised trial. A total of 48 adults with PGD who meet the eligibility criteria will be ran…
Relationship between skin temperature and muscle activation during incremental cycle exercise.
2015
While different studies showed that better fitness level adds to the efficiency of the thermoregulatory system, the relationship between muscular effort and skin temperature is still unknown. Therefore, the present study assessed the relationship between neuromuscular activation and skin temperature during cycle exercise. Ten physically active participants performed an incremental workload cycling test to exhaustion while neuromuscular activations were recorded (via surface electromyography - EMG) from rectus femoris, vastus lateralis, biceps femoris and gastrocnemius medialis. Thermographic images were recorded before, immediately after and 10 min after finishing the cycling test, at four …
Effects of strength vs. endurance training and their combination on physical performance characteristics in female horseback riders
2020
BACKGROUND: The purpose of this study was to investigate effects of strength (S), endurance (E) and concurrent strength and endurance (SE) training on neuromuscular and cardiorespiratory characteristics during the 12-week volume-equated protocols in female horseback riders. METHODS: Subjects (N=44) (29.4±8.9 yrs) were assigned to S (n=11), E (n=11), SE (n=13) and control (C) (n=9) groups. Training consisted of progressive S, E or SE training 3x/week and riding exercise 4-6x/week. The measurements included maximal isometric bilateral leg press force (MVCLP) and EMG of VL and BF muscles, rapid isometric force production (0-500ms), maximal force of trunk extensor/flexors (MVCE/MVCF), countermo…
Morphea after silicone gel breast implantation for cosmetic reasons in an HLA-B8,DR3-positive woman
1997
We describe an HLA-B8, DR3-positive patient with localized morphea after silicone gel breast implantation for cosmetic reasons. We believe that this case suggests that a genetic background, i.e. HLA-B8, DR3 haplotype, is involved in the autoimmune response to silicone.
Riscoprire l'ultima età della vita. Una riflessione pedagogica sulla vecchiaia. Rediscovering the last age of life. A pedagogical reflection on old a…
2018
This paper sets out from the consideration that nowadays old age is increasingly a source of new fears; these fears seem to translate into obsessive forms of a search for eternal youth. By way of a close comparison between the last two stages of life, adulthood and old age, the paper reviews some aspects of old age as a stage in the life cycle of the individual. First of all, the need to recover the dimension of gratitude is firmly underscored, translating into genuine care for the pact between generations. Gratitude and gratuity, which are opposed to envy and despair, appear as the essential elements of a sense of integrity in old age. However, integrity is only possible through family and…
Multisensor comparison of NDVI for a semi‐arid environment in Spain
2009
The joint use of multiresolution sensors from different satellites offers many opportunities to describe vegetation and its dynamics. This paper introduces the concept of a virtual constellation (defined as an ensemble of all Earth Observation satellites in orbit that satisfy common requirements) for agricultural applications and contributes to providing the necessary inter-sensor calibration methodology for spectral reflectances and NDVI. For this purpose, we performed an observational study, comparing reflectances and the Normalized Difference Vegetation Index (NDVI), from near-synchronous image pairs of Landsat 7 Enhanced Thematic Mapper Plus (ETM+), as the reference sensor and Landsat 5…
Use of Information from Clinical Trials for an Integrated Cancer Registry
1990
AbstractThe registry of childhood malignancies in the F.R.G. is a combination of a population-based and hospital-based cancer registry. A large amount of the collected data originates from multicenter clinical trials which are integrated into the documentation system of the cancer registry. The paper describes the information flow and the system of data storage which consists of a central database on a departmental system at the registry and of several coordinated peripheral databases on microcomputers at the trial centers. Practical experience shows an increased availability and validity of the data in the registry since the implementation of the system. Aspects of data integrity and secur…
Un approccio semplificato per il calcolo del load flow nelle smart grids basato su misure distribuite in bassa tensione
2017
I sistemi di misura distribuiti sono alla base delle "smart distribution grids", ove la crescente presenza di generazione distribuita e sistemi di accumulo e la conseguente transizione verso sistemi attivi rendono necessarie funzionalità avanzate di monitoraggio, controllo e gestione delle reti. In tale contesto, un elemento essenziale è l'analisi dei flussi di potenza, che, com'è noto, può essere effettuata tramite algoritmi di load flow, noti il modello della rete e le potenze generate/assorbite nei vari nodi. Per la misura di tali grandezze sulla media tensione (MT), si possono utilizzare diversi strumenti (quali phasor measurement units, smart meters, power quality analyzers), che però …
