To examine the relationship between upper respiratory illness (URI) incidence with changes in mucosal immunity (saliva immunoglobulin A (s-IgA) and saliva lysozyme (s-Lys)) training load (TL) a squad of elite rugby union players.Timed resting morning samples were taken from players (n = 31) at preselected time points for 11 months. Weekly rates TL assessed using Web-based diary medical/coaching staff reports.No significant correlation was found absolute s-IgA or s-Lys concentrations URI...

Memories are not confined to those who experience them firsthand. Rather, they can be transmitted and repeated by subsequent generations as prosthetic moral memories, linked solely specific geographic locations but extending affect inform contemporary political debates. This paper investigates how why the 1965 flooding of village Capel Celyn in Tryweryn valley, north Wales is remembered through textual analysis Welsh literature popular music. It also highlights profound impact that struggles...

Fault activity within the Lebanese transpression zone, one of classic examples restraining bend development on a continental transform, is here investigated using dated geomorphological features. The northern part Yammouneh Fault, commonly considered to be principal active strand this Dead Sea Transform, has been inactive for past 5 Ma. Field observations show that basalts, as late Pliocene hi age, apparently offset by fault, unconformably overlie it. transcurrent structure principally,...

Abstract Structural evolution along continental transform faults may be related to fault zone geometry and regional variations in plate kinematics. Using a case study of the Lebanese sector Dead Sea Transform, finite transpression at restraining bend can shown have evolved time. Relative structural chronologies, calibrated against dated landscape features such as lava-covered palaeosurfaces, coastal erosion surfaces their incised drainage basins, are used establish timing displacement...

Abstract. Being able to accurately estimate parameters characterising land surface interactions is currently a key scientific priority due their central role in the Earth's global energy and water cycle. To this end, some approaches have been based on utilising synergies between models Earth observation (EO) data retrieve relevant parameters. One such model SimSphere, use of which expanding, either as stand-alone application or synergistically with EO data. The present study aimed at...

Abstract Kinesio‐tape ® has been suggested to increase blood circulation and lymph flow might influence the muscle's ability maintain strength during fatigue. Therefore, aim of this study was investigate gluteal on lower limb muscle in non‐fatigued fatigued conditions. A total 10 male rugby union players performed 20‐m sprint vertical jump tests before after a rugby‐specific fatigue protocol. The time collected using light gates (SMARTSPEED). 9‐camera motion analysis system (VICON, 100 Hz)...

In today’s changing climate, the development of robust, accurate and globally applicable models is imperative for a wider understanding Earth’s terrestrial biosphere. Moreover, an representation, sensitivity coherence such are vital operationalisation any physically based model. A Global Sensitivity Analysis (GSA) was conducted on SimSphere land biosphere model in which meta-modelling method adopting Bayesian theory implemented. Initially, effects assuming uniform probability distribution...

The health benefits of a diet rich in omega-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA) no longer need to be proven. However, while authorities attempt increase the consumption n-3 LC-PUFAs eicosapentaenoic acid (EPA) and docosahexaenoic (DHA), data from latest intake surveys demonstrate that EPA DHA is still too low.

Coastal erosion and sea level rise has become a significant threat to coastal heritage due climate change. Management bodies are monitoring the risks posed by undertaking studies, ranging from Rapid Zone Assessments much larger government research council funded studies. These studies have incorporated varying techniques datasets such as environmental sampling, LiDAR, GPS, UAV surveys. However, these approaches rarely combine study of historic shoreline change with physical susceptibility...
