Cardiac response to Nage no Kata in judo

2021

The first world judo Kata competition was held in October 2007 in Tokyo, Japan. The Nage no Kata was developed in 1884 and 1885 at the Kodokan. by Jigoro Kano, the founder of judo, who developed Kata to demonstrate the principles of judo and to provide a type of training which emphasized performing techniques under controlled setting. According to Kano, to fully develop judo skills, it is essential to involve both Randori and Kata techniques [1]. Most highgrade Japanese judo teachers emphasize the importance of Kata performance for judokas’ development, in particular Nage no Kata [2]. Results of the study conducted by Canestri et al. [3] suggested that session-RPE and HR monitoring is a sim…

Maternal cell phone use during pregnancy and child cognition at age 5 years in 3 birth cohorts

2018

Background: There have been few studies of children's cognitive development in relation to mothers' cell phone use, and most were limited to outcomes at age 3 years or younger. We examined the relationship between maternal cell phone use during pregnancy and cognitive performance in 5-year old children. Methods: This study included data from 3 birth cohorts: the Danish National Birth Cohort (DNBC) (n = 1209), Spanish Environment and Childhood Project (INMA) (n = 1383), and Korean Mothers and Children's Environment Health Study (MOCEH) (n = 497). All cohorts collected information about maternal cell phone use during pregnancy and cognitive performance in children at age 5. We performed linea…

Safety culture assessment in high reliability organizations: the use of questionnaires in the nuclear industry

2017

El objetivo principal de esta tesis es proporcionar una visión general de las formas actuales de entender, tratar, y evaluar la cultura de la seguridad (poniendo un énfasis particular en la industria nuclear y en la utilización de cuestionarios), y proporcionar orientación a los investigadores y profesionales sobre cómo capturar la cultura de seguridad de las centrales nucleares. Para ello, la tesis actual incluye los siguientes capítulos: CAPÍTULO I - Se presenta una breve introducción a la industria nuclear. Asimismo se presentan algunos de los más destacables pros y contras de la energía nuclear, y desafíos importantes a los que la industria nuclear se estado enfrentando en los últimos a…

Immediate Nonfunctional Loading of NobelPerfect Implants in the Anterior Dental Arch in Private Practice - 5-Year Data

2012

Background: The concept of scalloped implants to maintain the natural contour of the alveolar ridge has been a source of controversy for many years. Purpose: This study examined the long-term clinical performance of the scalloped NobelPerfect implant in a one-stage procedure (immediate loading in the esthetic zone). Materials and Methods: In 20 patients, immediate prosthetic restorations were placed on 31 NobelPerfect implants in a private practice and followed for up to 78 months. Twenty-one implants were placed immediately after extraction, seven implants were placed after osseous consolidation of the extraction sockets, and three implants were placed secondary to extended alveolar ridge …

Semaphorin 6A Improves Functional Recovery in Conjunction with Motor Training after Cerebral Ischemia

2010

Stroke is a major health problem in industrialized societies. Despite numerous attempts at developing acute stroke therapies aimed at minimizing acute infarct development, the only approved therapy so far is recombinant tissue plasminogen activator (rtPA). In recent years, the attention of the stroke community has therefore also put increased emphasis on understanding processes of post-stroke recovery, and their potential exploitability for therapeutic purposes. The brain has a remarkable ability to adapt to changes after stroke. Mechanisms that contribute to this plasticity are re-mapping and expansion of cortical areas to neighboring regions of functional motor cortex areas after injury […

Does short-term odour memory increase with expertise? An experimental study with perfumers, flavourists, trained panellists and novices

2011

We have examined short-term memory performance for odour recognition as a function of expertise. Experts (perfumers and flavourists), trained panellists, and novices studied three sets of common and uncommon (perfumery and flavour raw materials) odours with intentional encoding instructions. The three sets included three, six and 12 odours, respectively. As expected, recognition performance indicated an expertise effect: hit rates increased with expertise, whereas false alarm rates decreased. This effect, however, is mediated by the type and number of odours. For common odours, the effect of expertise is significant only for the larger odour set. For uncommon odours, the effect of expertise…

Ecosystem Adversity as Setting Factors in Mothers' Judgment of Child Behavior and Indiscriminate Mothering

1996

Several studies have shown that troubled mothers are not accurate observers of their children's behavior. These mothers have a global and usually blame-oriented reporting style coloured by disphoric views of social isolation, social coercion and socioeconomic disadvantage. The dsyphoric view describes a number of contextual or setting factors that seem to influence a mother's observational reports about her child more than the child's actual behavior does. Of course, when this observational bias exists, the mother's parenting performance is bound to be comprised. According to the considerations above, this study was designed with a group of 21 mother-child dyads characterized by their coer…

Modulation of the growth and metabolic response of cyanobacteria by the multifaceted activity of naringenin

2017

The interactions between the plant-derived bioflavonoid, naringenin, and prokaryotic microalgae representatives (cyanobacteria), were investigated with respect to its influence on the growth and metabolic response of these microorganisms. To achieve reliable results, the growth of cyanobacteria was determined based on measurements of chlorophyll content, morphological changes were assessed through microscopic observations, and the chemical response of cells was determined using liquid and gas chromatography (HPLC; GC-FID). The results show that micromolar levels of naringenin stimulated the growth of cyanobacteria. Increased growth was observed for halophilic strains at naringenin concentra…

Isolation of chlorinated dibenzothiophenes by high-performance thin-layer chromatography

1991

Abstract Chlorinated dibenzothiophenes can cause environmental problems analogous to chlorinated dibenzodioxins and dibenzofurans. In the analysis of chlorinated dibenzodioxins by gas chromatography—mass spectrometry some unknown chlorinated compounds have been found. The chlorinated dibenzothiophenes have the same m/z values as the corresponding dioxins in low-resolution mass spectrometry and they are found in same planar aromatic compound fraction in alumina and carbon column chromatography. Some chlorinated dibenzothiophenes were synthesized to serve as model compounds in analytical work. High-performance thin-layer chromatography (TLC) with different plates and several eluents was tried…
