Mechanical properties and XRD of Nafion modified by 2-hydroxyethylammonium ionic liquids

2013

In this work, the Nafion 112 membrane impregnated with 2-hydroxyethylammonium carboxylate ionic liquids have been investigated. The used ionic liquids were 2-hydroxyethylammonium formate [HEA]F, acetate [HEA]A and lactate [HEA]L. Prepared composite membranes Nafion/ionic liquid are characterized by mechanical testing, such as tensile test and creep test. It is found that ionic liquids decrease elastic modulus and creep compliance, but do not have significant effect on the tensile strength. Also, composite membranes were studied by wide angle X-ray diffraction. All ionic liquids shift the peak maximum to the lower angle. In this work, only biodegradable ionic liquids were used for composite …

The Effects of Resistance Training on Physical Fitness and Neuromotor-Cognitive Functions in Adults With Down Syndrome

2022

Adults with Down syndrome are an underserved population at high risk for a host of different pathologies from aging and lack of activity.PurposeTo examine the effects of a 10-week resistance training program on measures of motor behavior, cognitive function, mood, and physical fitness.MethodsParticipants (n = 11) were men and women clinically diagnosed with Down syndrome (age: 25.8 ± 6.4 years; height: 151.5 ± 8.3 cm; weight: 67.5 ± 13.0 kg; IQ: 58.3 ± 19.7 units). After familiarization of testing procedures, subjects performed The Arizona Cognitive Test Battery for Down Syndrome, TGMD-2, lower and upper body strength assessments, and body composition via DXA testing, while parental guardia…

Rapid Weight Loss Alters Handgrip Strength In Greco-Roman Wrestlers

Effects of rapid weight loss (RWL) on handgrip strength (HGS) in combat sports athletes are still quite indefinite. The aim of this study was to delineate the effect of RWL on HGS in Greco-Roman wrestlers. Handgrip strength was measured during three time points. Baseline measurement was carried out before the weight reduction. Second measurement was done after sport specific training combined together with RWL. Finally, third measurement was carried out after sport specific training alone. Results showed that HGS was significantly greater after a training combined with RWL procedure compared to only specific training for one hand. Findings of this study could potentially improve the trainin…

Influence of time-of-day-specific same-session combined endurance and strength training on maximal and submaximal endurance parameters

2015

Endurance and strength training are often performed concurrently by both elite athletes and recreational individuals. The question of whether the order of exercises or training at certain daytimes yields to different adaptations in endurance and strength parameters, when endurance and strength training are combined into a single training session, has received limited scientific attention. Moreover, effects on cardiorespiratory and neuromuscular variables after same-session concurrent training have shown conflicting results, particularly regarding exercise sequence or time-of-day characteristics. The purpose of the present study was to examine the effect of time-of-day-specific same- session…

Neuromuscular adaptations to single-session combined strength and endurance training in untrained men : an examination of the order effect

2013

Understanding the adaptations to single-session combined strength (S) and endurance (E) training has received increased attention in scientific literature through the expand-ing use of combined training programs for practical purposes. However, the intra-session exercise order when performing both E and S in the same training session may limit potential strength development, as the neuromuscular adaptations to either training mode alone are very different. Research on the effect of the intra-session exercise order of combined training on various training-induced adaptations, i.e. the order effect, is currently limited, especially with regard to the neuromuscular adaptations. Therefore, the …

Clarifying Skills and Competencies in Organisational Decision Making – Perceptions of Finnish Communication Professionals

2017

This paper seeks to better understand the skills and competencies that Public Relations (PR) professionals use in contributing to organisational decision-making processes. The data were collected by interviewing Finnish professionals using thematic semi-structured interviews. Overall, the results highlight a deep understanding of organisation management and decision-making processes. The most important competencies were business understanding and target group oriented thinking. The findings indicate that important skills are related to writing and social media. ‘Regarding personal attributes, interaction and tolerance to criticism were acknowledged as most crucial. The conclusions suggest t…

Cytotoxicity investigations of plasma sprayed calcium phosphate coatings

1994

One potential alternative material to replace hydroxyapatite (HAp) as a coating material for plasma-sprayed coatings on implants for hip replacement is fluorapatite (FAp). FAp has advantages over HAp regarding the capability of being chemically stable during the coating process. This leads to surface coatings containing high apatite rates with a mechanical stability (bond strength, microhardness) comparable to HAp. From the technical point of view the production of FAp coatings is well investigated, although studies on biocompatibility of FAp coatings are fewer. This paper reports the production of HAp and FAp coatings with varying solubilities by plasma spraying and their in vitro cytotoxi…

Innovative Recycling of Lime Slaker Grits from Paper-Pulp Industry Reused as Aggregate in Ambient Cured Biomass Fly Ash-Based Geopolymers for Sustain…

2019

Lime slaker grits and biomass fly ash are solid wastes produced by the Kraft paper-pulp industry that are commonly disposed of in landfill. However, recent studies and European regulations discourage such disposal practices. This work investigates an alternative and innovative way to recycle and reuse these wastes in the production of green geopolymeric mortars intended for application in the construction industry. Here, biomass fly ash was used as the main source of alumino-silicate in the binder precursor (70 wt.% substitution to metakaolin), and grits (ranging from 1&ndash

Effects of electrical stimulation pattern on quadriceps isometric force and fatigue in individuals with spinal cord injury

2015

Introduction Variable frequency trains (VFT) or train combinations have been suggested as useful strategies to offset the rapid fatigue induced by constant frequency trains (CFT) during electrical stimulation. However, most studies have been of short duration with limited functional application in those with spinal cord injury (SCI). We therefore tested force and fatigue in response to VFT, CFT, and combined patterns in strength training-like conditions (6-s contractions). Methods Ten SCI individuals underwent either CFT or VFT patterns until target torque was no longer produced and then switched immediately to the other pattern. Results Target torque was reached more times when VFT was use…
