Measuring Wetland Restoration Success through Water Quality and Invertebrate Community Indices

Wetland restoration projects are essential to preserving these imperiled ecosystems. While restoring lost or degraded wetlands is the first step, determining the success of these restoration efforts is often difficult or only focuses on one aspect of an ecosystem (e.g., water quality testing). I plan to measure the success of wetland restoration through traditional (i.e., water quality testing) and non-traditional methods (i.e., terrestrial and aquatic insect sampling) in native (i.e., control) and restored (i.e., experimental) wetlands in Ohio. I will use sweep nets for aboveground insect collection and a dip net for aquatic macroinvertebrate collection. These samples will be sorted, counted, and identified (to at least the family level) in the lab, where we will determine how terrestrial insect and aquatic macroinvertebrate community indices (e.g., Shannon diversity, richness, evenness) indicate the health of restored wetlands. Water quality testing will be performed using a YSI probe, measuring dissolved oxygen, pH, conductivity, temperature, and nitrates. The values collected for these characteristics will be compared to native wetlands and known standard water health metrics. By combining traditional (i.e., water quality testing) with non-traditional sampling techniques, the results of this project will provide a novel method to determine the health of restored wetlands. Using these results, we will be able to work with and advise local soil and water conservation districts how best to invest their money and resources for wetland preservation. This project will be essential for the health of our wetlands in Ohio

Municipal Industrial Development Bonds

Several years ago a national business magazine carried an article styled You Gotta Have A Golf Course. \u27 The article outlined the efforts of a small town to attract new industry and the awkward realization by the city fathers that they were losing out to the competition because their community lacked such a recreational facility. After this finding, several public spirited citizens raised the necessary funds and constructed a nine-hole course. These efforts were soon rewarded when a large industrial concern located a new manufacturing plant in their city. Industrial development bonds are essentially intended to serve the same purpose as this golf course, and, at least from the point of view of the issuer, this paper could be sub-titled You Gotta Have the Money. One of the principal problems facing any industrial concern that may be considering the addition of a new facility is financing the cost of this venture. Therefore, when the municipality concerned present\u27a ready-made and expense-saving solution to this problem, a major obstacle is cleared and the relative bargaining position of the municipality is proportionately increased. In recent years, and with a marked increase during the past decade, many states have authorized their counties and municipalities to issue industrial development bonds for the declared purpose of providing increased and more diversified employment

Interhemispheric comparison of atmospheric circulation features as evaluated from NIMBUS satellite data

Findings are presented for IRIS data from NIMBUS 3 in mapping the global ozone distribution. The seasonal and regional variations of ozone, especially in the Southern Hemisphere, reveal features that were not evident from the sparse ground-based ozone observation network in this hemisphere. A regression analysis was undertaken for temperature and height fields on radiance data. Spectrum analyses of upper wind data from the North American section and Australia were completed

Analysis of Vertebrae Pathologies of Grave A650 Chryssi Island, Crete, Greece

This study of multiple, co-mingled adult individuals located in grave A650 on Chryssi Island, Crete, Greece, examines the prevalence of several pathologies of the vertebrae. This grave was built into a collapsed Late Minoan period house (1400-1100 B.C.E.). Grave A650, which likely dates to the 5th – 7th century C.E., shows evidence of being used over a long period of time and may have served as an ossuary. The pathologies of approximately 30 recovered vertebrae, both complete and incomplete, show signs of degenerative joint disease, spondylolisthesis, and body expansion. Researching this data aims to accomplish a comprehensive understanding of what the present pathologies indicate about the physical activity endured by individuals during their lifetime. Conclusions of this data reveal these co-mingled individuals endured intense and sustained physical activity throughout their lives. There were high numbers of degenerative joint diseases in the thoracic vertebrae, which could indicate repetitive movement in bending down. A plausible cause of this intense labor could be slavery, as revealed by accompanying evidence in the ossuary itself

The impact of low energy proton damage on the operational characteristics of EPIC-MOS CCDs

The University of Tübingen 3.5 MeV Van de Graaf accelerator facility was used to investigate the effect of low energy protons on the performance of the European Photon Imaging Camera (EPIC), metal–oxide semiconductor (MOS), charge coupled devices (CCDs). Two CCDs were irradiated in different parts of their detecting areas using different proton spectra and dose rates. Iron-55 was the calibration source in all cases and was used to measure any increases in charge transfer inefficiency (CTI) and spectral resolution of the CCDs. Additional changes in the CCD bright pixel table and changes in the low X-ray energy response of the device were examined. The Monte Carlo code Stopping Range of Ions in Matter (SRIM) was used to model the effect of a 10 MeV equivalent fluence of protons interacting with the CCD. Since the non-ionising energy loss (NIEL) function could not be applied effectively at such low proton energies. From the 10 MeV values, the expected CTI degradation could be calculated and then compared to the measured CTI changes

Incorporation of a nanotechnology-based additive in cementitious products for clay stabilisation

The mechanical performances and water retention characteristics of clays, stabilised by partial substitution of cement with by-products and inclusion of a nanotechnology-based additive called RoadCem (RC), are studied in this research. The unconfined compression tests and one-dimensional oedometer swelling were performed after 7 d of curing to understand the influence of addition of 1% of RC material in the stabilised soils with the cement partially replaced by 49%, 59% and 69% of ground granulated blast furnace slag (GBBS) or pulverised fuel ash (PFA). The moisture retention capacity of the stabilised clays was also explored using the soil-water retention curve (SWRC) from the measured suctions. Results confirmed an obvious effect of the use of RC with the obtained strength and swell properties of the stabilised clays suitable for road application at 50% replacement of cement. This outcome is associated with the in-depth and penetrating hydration of the cementitious materials by the RC and water which results in the production of needle-like matrix with interlocking filaments – a phenomenon referred to as the ‘wrapping’ effect. On the other hand, the SWRC used to describe the water holding capacity and corresponding swell mechanism of clays stabilised by a proportion of RC showed a satisfactory response. The moisture retention of the RC-modified clays was initially higher but reduced subsequently as the saturation level increased with decreasing suction. This phenomenon confirmed that clays stabilised by including the RC are water-proof in nature, thus ensuring reduced porosity and suction even at reduced water content. Overall, the stabilised clays with the combination of cement, GGBS and RC showed a better performance compared to those with the PFA included

Equivalence Study of a Dental Anatomy Computer-Assisted Learning Program

Tooth Morphology is a computer-assisted learning program designed to teach the anatomy of the adult dentition. The purpose of this study was to test whether Tooth Morphology could teach dental anatomy to first-year dental students as well as the traditional lecture. A randomized controlled trial was performed with forty-five first-year dental students. The students were randomly assigned to either the Tooth Morphology group (n=23), which used the computer-assisted learning program and did not attend lecture, or the lecture group (n=22), which attended the traditional lecture and did not useTooth Morphology. The Tooth Morphology group had a final exam average of 90.0 (standard deviation=5.2), and the lecture group had a final exam average of 90.9 (sd=5.3). Analysis showed that the two groups’ scores were statistically equivalent (p\u3c0.05), with a priori equivalence bounds around the difference between the groups set at +/−5 points. It was concluded that Tooth Morphology taught the anatomy of the adult dentition as well as traditional lecture, as measured by exams. Based on the results of this study and student feedback, Tooth Morphology, in combination with interactive class meetings, has replaced the traditional dental anatomy lectures

Cathodal electrical stimulation of frontoparietal cortex disrupts statistical learning of visual configural information

Attentional performance is facilitated by exploiting regularities and redundancies in the environment by way of incidental statistical learning. For example, during visual search, response times to a target are reduced by repeating distractor configurations-a phenomenon known as contextual cueing (Chun & Jiang, 1998). A range of neuroscientific methods have provided evidence that incidental statistical learning relies on subcortical neural structures associated with long-term memory, such as the hippocampus. Functional neuroimaging studies have also implicated the prefrontal cortex (PFC) and posterior parietal cortex (PPC) in contextual cueing. However, the extent to which these cortical regions are causally involved in statistical learning remains unclear. Here, we delivered anodal, cathodal, or sham transcranial direct current stimulation (tDCS) to the left PFC and left PPC online while participants performed a contextual cueing task. Cathodal stimulation of both PFC and PPC disrupted the early cuing effect, relative to sham and anodal stimulation. These findings causally implicate frontoparietal regions in incidental statistical learning that acts on visual configural information. We speculate that contextual cueing may rely on the availability of cognitive control resources in frontal and parietal regions
