    Channel rehabilitation to increase aquatic habitat and reestablish floodplain connectivity on the Upper Gila River

    Stream restoration is an opportunity to recover a substantial amount of lost ecosystem structure and function. This may be particularly beneficial for perennial streams in semi-arid regions because of the striking differences in productivity and biodiversity between the riparian corridor and surrounding uplands. We develop a plan to restore floodplain connectivity along a channelized reach of the unregulated Upper Gila River in southwestern New Mexico, and evaluate its potential to provide additional aquatic habitat. To identify the extent of historical channelization, primary and secondary documents are examined. Signs of current geomorphic processes are also considered to formulate a restoration design. A high-resolution elevation model of the channel and floodplain is built from Light Detection and Ranging (LIDAR) and channel survey data, and an additional elevation model is created that includes the restoration plan. The plan consists of a new overflow channel in the disconnected floodplain, and is evaluated using a hydraulic model of open channel flow built with stream geometry information from the georeferenced elevation model. Flow levels for the study are chosen and characterized based on the 83-year record of daily mean discharge measured at the gaging station immediately upstream of the study site. The hydraulic simulation estimates for total area, total volume, and patterns of inundation in the study reach are used to evaluate the change in aquatic habitat availability and floodplain connectivity for the restoration plan. Results show that the reconfigured channel pattern would provide unique backwater habitat in the reach, and it also would increase total flooded area and floodplain connectivity throughout the entire range of modeled discharges

    Effect of EpiCor supplementation on delayed onset muscle soreness and inflammation after unaccustomed, eccentric resistance exercise

    Unaccustomed eccentric exercise has been well documented to elicit muscle damage and an inflammatory response to help fix and restore the impaired muscle fibers. Supplements, including anti-inflammatories and antioxidants have been used to help alleviate the damage and decrease the inflammation but positive results are slim. It is proposed that EpiCor, a yeast metabolite with suggested anti-inflammatory and antioxidant characteristics, would decrease the amount of muscle soreness and inflammation that results from unaccustomed eccentric exercise. Thirty-two male subjects (ages 18-35) ingested a once daily 500mg dose of either EpiCor or placebo 4 weeks prior to the eccentric exercise bout. This matched pairs, double blind study randomly assigned subjects to either group and were matched based on a peak, pre-exercise maximal isometric contraction. Subjects then performed 50 maximal eccentric contractions of the elbow flexors at 30 degrees per second on each arm. Blood samples were taken at pre-, 24, 48, and 72 hours post-exercise, in addition to psychological and illness surveys. Muscle damage, soreness and circumference all had a significant effect of time throughout the 72 hour recovery period (P\u3c0.001). Elevated levels of CK and LDH were also present with a significant effect of time (P\u3c0.05); however, there were no significant differences between treatments for muscle damage indicators. Results for inflammatory markers were similar in that no statistically significant difference between groups existed for IL-1ra, IL-6, IL-10, and CRP, but some non-significant trends (P\u3c.11) did exist. These results do not support the hypothesized effects for EpiCor in reducing the muscle damage, soreness, and inflammation after an unaccustomed eccentric exercise bout of the elbow flexors. This supplement needs further research into the effectiveness of its use in an exercise setting

    Adolescent autistic traits and internalising traits: quantitative genetic investigations of co-occurrence patterns

    Get PDF
    Autism spectrum disorders (ASD) are characterised by social-communication difficulties and non-social symptoms such as restricted and repetitive behaviours and interests. ASD characteristics can be investigated at the subclinical trait level within the general population, and these quantitative autistic traits have been shown to have a smooth distribution. Adolescence is an important developmental stage, particularly for the emergence of internalising problems. However, few studies to date have investigated the causes of co-occurring autistic traits and internalising traits during adolescence. The aim of this thesis is to explore the aetiological causes of this trait association between the ages of 12 to 16 years using a quantitative genetic approach. This thesis employs a classic twin design and the sample came from the Twins Early Development Study (TEDS). The causes of the association between autistic and internalising traits in early adolescence are the first focus of this thesis. The analyses in Chapter 4 explore this aetiological association at ages 12-14 years, revealing a moderate phenotypic trait association and at the aetiological level moderate genetic overlap, substantial shared environmental and modest nonshared environmental overlap. Teasing apart these associations further, Chapter 5 identifies specific autistic-like behaviours by means of factor analysis. Relating these factor-derived autistic trait subdomains to the internalising trait measure demonstrated distinguishable patterns of phenotypic and aetiological associations. A factor named autistic-like ‘Social Unease’ showed the most phenotypic and genetic overlap with internalising traits. Secondly, this thesis investigates in Chapter 6 the role of childhood nonshared environment on internalising and autistic traits in early adolescence using the monozygotic twin differences design. Analyses showed that birth weight, childhood hyperactivity and peer problems played a role, via the nonshared environment, in influencing individual differences in internalising and autistic traits in early adolescence. Finally, Chapter 7 presents findings on later adolescence, at age 16 years, exploring the association of autistic traits with anxiety traits and depression traits separately and drawing on both parent and self ratings. The implications of these findings, their limitations and their contribution to the current literature are considered in the Discussion (Chapter 8)

    The Ideological Dilemmas Inherent in Informal Learning Spaces: A Discourse Analysis of Preservice Teacher Talk

    Get PDF
    Informal learning spaces, such as summer reading programs, have the potential to both motivate children and provide opportunities for preservice teachers to try out new practices. However, there is little research on the talk that occurs in these informal learning spaces, particularly those intended to function as third spaces. Audio recordings of meetings between preservice teachers and high school students talking together about young adult literature in a space intended to function as a third space were analyzed to explore how discourse choices shaped the participants\u27 practices. We found that the participants both resisted and reproduced the traditional classroom in their talk, suggesting that the successful design of third spaces is a complex endeavor

    Using Semantic Segmentation for the Damage Detection of Port and Marine Infrastructures

    The ageing infrastructure in ports requires regular inspection. This inspection is currently carried out manually by sensing the entire infrastructure by hand. Such a process is costly as it requires a lot of time and manpower. To overcome these difficulties, we propose to map the harbour structure above and below water with a multi-sensor system and try to automate the classification process in terms of common damage types using deep learning approaches. In the images taken \rev{above} water, damaged and undamaged zones are localised using a semantic segmentation approach. We make use of a real data set captured at JadeWeserPort Wilhemlshaven to test our approach. The images are divided into smaller sections of 512x512 pixels and these are propagated through the DeepLabv3+ architecture, a modern convolutional neural network for semantic segmentation tasks, which is trained in particular to detect corrosion or rust anomalies. We achieve with a pre-trained ResNet-50 backbone and fully supervised data set IoU scores of 96.0 % and 55.9 % for undamaged and damaged zones as well as F1-scores of 98.0 % and 71.7 %. We show that our approach can achieve a fully automated and reproducible image segmentation and damage detection which can analyse the whole structure instead of the sample-wise manual method.Bundesministerium für Digitales und Verkehr/Innovative Hafentechnologien/19H18011
