The Telecommunications Marine Laboratory (TML) of the University of Cádiz takes part in a research project to study the intertidal sediments of the Bay of Cádiz. The collection of samples from the seabed and the transmission of data to the surface are performed by a Mini Profiler with four channels (MP4), which is supplied by UNISENSE. Each channel processes the samples collected by a single sensor. For power, control, and data transmission, a special wiring that connects the submerged subsystem with the surface subsystem is used. The tension transmitted by the cable to the MP4 structure makes its handling and positioning under water more difficult. This article explains the technological solution developed by the TML to replace some wiring from the MP4. For the prototype, two underwater acoustic modems have been used and an electronic system has been developed based on the Arduino platform, in order to multiplex, digitize, and transmit the data collected by the MP4 sensors, eliminating the need to use wiring. The submerged subsystem has an autonomous power supply by a battery.

Oxidative stress plays a key role in the pathogenesis of ischemic stroke. Coenzyme Q10 has a multi-targeting effect and may protect the brain against ischemic damage. The aim of our study was to evaluate the neuroprotective potential of ubiquinol by its intravenous administration. The study was performed on rats; a stroke was modeled by occlusion of the middle cerebral artery. On days 1 and 4 after ischemia, the neurological deficit and volume of the brain lesion were determined by MRI and TTC staining. Intravenous administration of coenzyme Q10 led to a decrease in rat mortality rate, improvement in neurological status, and decrease in the brain necrosis area in acute and delayed period after cerebral ischemia. A single intravenous administration of ubiquinol led to a limitation of the size of the brain damage for at least four days after ischemia. Thus, intravenous administration of coenzyme Q10 has a persistent neuroprotective potential. This finding suggests a possible therapeutic role of ubiquinol in acute ischemic conditions.

In the framework of the minimal quartet-metric gravity/systogravity, a scalar graviton/systolon is stated as a universal dark component, with supplementary manifestations in the different contexts either as dark matter or dark energy. An ensuing extension to the standard {Λ}CDM model is developed. A modification of the late expansion of the Universe, with an attractor of a scalar master equation defining an effective cosmological constant, which supersedes the true one, is proposed. A new partial solution to the cosmological constant problem is discussed. ; Comment: 11 pages

We explored the neuroprotective properties of natural plant-derived antioxidants plastoquinone and thymoquinone (2-demethylplastoquinone derivative) modified to be specifically accumulated in mitochondria. The modification was performed through chemical conjugation of the quinones with penetrating cations: Rhodamine 19 or tetraphenylphosphonium. Neuroprotective properties were evaluated in a model of middle cerebral artery occlusion. We demonstrate that the mitochondria-targeted compounds, introduced immediately after reperfusion, possess various neuroprotective potencies as judged by the lower brain damage and higher neurological status. Plastoquinone derivatives conjugated with rhodamine were the most efficient, and the least efficiency was shown by antioxidants conjugated with tetraphenylphosphonium. Antioxidants were administered intraperitoneally or intranasally with the latter demonstrating a high level of penetration into the brain tissue. The therapeutic effects of both ways of administration were similar. Long-term administration of antioxidants in low doses reduced the neurological deficit, but had no effect on the volume of brain damage. At present, cationic decylrhodamine derivatives of plastoquinone appear to be the most promising anti-ischemic mitochondria-targeted drugs of the quinone family. We suggest these antioxidants could be potentially used for a stroke treatment.

The focus of this paper is on the use of the Manufacturing System Design Decomposition (MSDD) to make effective cost and production system design decisions. A comparative study is conducted to illustrate how and why the total cost is reduced when the functional requirements defined by the MSDD are achieved. The ultimate goal of this research was to advance manufacturing and productionsystem development to being guided by engineering science and design rather than the common practice of duplicating another person’s or entity’s notion of the best physical implementation

We reviewed the current state of waste management practices in Nigeria using examples from different parts of the country. Commonly practiced waste disposal methods in Nigeria, such as burial, open-air burning, and open dumping, were found to be ineffective and detrimental to public health and the environment. It was also shown that waste management cannot be successfully operated as a social service. Rather, the generator of waste must be held responsible. Problems confronting efficient waste management in ..

Most people have this stigma or preconceived notion that growing older is a bad thing. What I have found is that we can learn a lot from people who are more seasoned with age, and they are still living and experiencing new things each and every single day. I love hearing their stories, and I think they need to be shared. My project is a collection of these life experiences and reflections, titled “A Life Well Lived”. To create this project I did extensive research through surveys and personal one on one interviews with the elderly population. Many of the people I interviewed multiple times, collecting stories and images about them. I asked them research questions and personal questions regarding their thoughts on aging. I compiled these stories into a project highlighting their outlook on life and their experience. Through this process, I began to understand how people feel about aging and hope to open up a dialogue on the subject. In this way, I hope to reduce the stigma and fear associated with aging.http://opus.ipfw.edu/stu_symp2017/1022/thumbnail.jp

Biological soil crusts (BSCs) are microbial assemblages that play important roles in the areas they inhabit, and can influence aspects such as local nitrogen flux, water infiltration, and plant seedling germination. In the dune environment, BSCs can form close connections with sand particles to stabilize dunes at their surface. Despite their potential critical role within Indiana Dunes State Park, little is known about their diversity, ecology, or interactions with plant communities there. The objective of this study, therefore, was to examine abiotic and biotic factors that influence dune BSCs, using Illumina high-throughput sequencing (HTS) to characterize these microbial communities. We hypothesized that specific environmental variables would influence BSC microbial diversity. In this study we sampled every 50m along a 550m transect, moving from the Lake Michigan shore inward to the hind-dune environment. At each sampling point soil pH, PAR, UV, and chlorophyll and scytonemin pigments were measured, and plant community cover, richness, and diversity were assessed. Moisture, conductivity, and nutrient content (total N and P) were also measured at every 100m. Overall, our HTS effort recovered 1,214,542 bacterial sequences across our 30 samples, and five major phyla were found to dominate our BSC samples, these being Proteobacteria (~20% of all sequences), Acidobacteria (~17%), Actinobacteria (~16%), Bacteriodetes (~17%), and Cyanobacteria (~10%). While there were no significant trends observed for BSC diversity moving along the transect, we did note a significant negative correlation for biological pigments and soil pH, suggesting a shift in the microbial community structure in response to these environmental parameters. The tendency for pH to structure terrestrial microbial communities has been noted in many studies; therefore, we are currently carrying out additional analyses to examine BSC community composition changes across our transect in relation to measured abiotic variables, with pH being of special interest.http://opus.ipfw.edu/stu_symp2017/1039/thumbnail.jp

A number of studies have found that a variety of political phenomena, including democracy, can spread through a diffusion process. It is also possible that non-democratic phenomena can follow a similar pattern. The spread of authoritarian regimes in Europe between World I and World War II provided a classic case to determine whether there were such patterns. In fact, the creation of authoritarian political systems followed a diffusion pattern in some periods under some circumstances. There were also indications that those countries that were at lower levels of economic development were a factor that led to the establishment of authoritarian political systems

Education of a child is mostly understood as teaching practices in schools, but education is also the child’s complete development. The purpose of this case study was to examine the multiple factors that influence a developing child’s cognitive, social emotional, language and physical development. The study considered the ecological factors based on Bronfenbrenneru27s Ecological Theory (home, school and community) that contribute to the child’s learning and development (McDevitt u26 Ormrod, 2016). This case study uses Bronfenbrenner’s theory to examine the contextual influences on a developing child through analyzes of the child’s individual self within the microsystem of school, peers, family and community. This inquiry was a 15-week case study that was conducted at a local school in Fort Wayne Community Schools in which one child was observed in the school setting. During the fifteen weeks of the case study, I did six naturalistic observations of the child in the school setting, engaged in informal interviews with the child, teacher and other school staff and collected anecdotal field notes. As a student teacher intern and researcher, I also spent time working with the child one-on-one in the classroom and got to know him on a personal level. The observations were analyzed using concepts of child development research and theories of child development to learn about one child’s unique experience in the classroom. This case study demonstrated a real-life experience of a child and the influential factors of child development looking at cognitive, social emotional, language and physical development. Knowledge acquired during this study was understanding a child’s thought process of the world and learning, good relationships with peers, socialization, and the importance of active and competitive play in school for boys. This case study demonstrates the importance of not only to teaching and mentoring students in the classroom but accommodating content based on each students’ needs.http://opus.ipfw.edu/stu_symp2017/1009/thumbnail.jp

In this poster presentation, the author examines how core competencies of technical communication incorporate information systems and project management. The presentation explores particular data governance concepts that can be used to expand upon Hart-Davidson’s (2001) “core competencies of technical communicators” and Redish’s (2010) four elements of successful technical communication. Data governance defines roles and “assigns responsibilities for decision areas to these roles,” while establishing standards and ensuring compliance with strategies on an organization-wide basis (Weber, Otto, and Österle, 2009, p. 2). Technical communicators should be versatile and add value to their organizations and products (Dubinsky, 2015), as seen by the growing variety of competencies identified by Brumberger and Lauer (2015). These competencies connect technical communication to information systems and project management, as well as other fields. The presentation explores how this added value corresponds to Nardi and O’Day’s (1999) idea of the workplace “gardener,” an individual who grows productivity in his or her workplace. Specifically, this presentation demonstrates methods of bridging the fields of information systems and technical communication, elevating technical communication from its traditional support role by utilizing data governance concepts and versatile workplace “gardeners.”http://opus.ipfw.edu/stu_symp2017/1032/thumbnail.jp

Biological soil crusts (BSCs) are associations between microorganisms and the surface of the soil that occur in relatively undisturbed soils exposed to sunlight. They have been shown to stabilize soils and contribute to nutrient cycling in otherwise barren soils. Cyanobacteria are important microorganisms in BSCs because they initiate their development, serve as primary producers, and provide stability for the BSC microbial ecosystem. BSCs are known for their presence in open areas such as deserts, although they can be found in the more temperate environment of the Indiana Dunes State Park in the sand dunes along the Lake Michigan Lakeshore. With increasing temperatures, it is unknown as to how BSC microbial communities will respond and how a changing climate will specifically impact the cyanobacteria within these soils. Therefore, the objective of this research is to isolate cyanobacteria from BSCs of the Indiana Dunes and observe their temperature tolerance in comparison to cyanobacteria from arid deserts of the western US. It is hypothesized that strains from the Indiana Dunes will be more psychrotolerant and respond more similarly to Microcoleus vaginatus from the Colorado Plateau, than Microcoleus steenstrupii from the Sonoran Desert. Two strains of cyanobacteria were isolated from the Indiana Dunes and, following PCR and sequencing, were determined to most likely be strains of Leptolyngbya and Pseudophormidium. These two isolates, M. vaginatus, and M. steenstrupii were allowed to grow for 20 days at 10, 25 and 35oC. Their growth and survival will be determined by changes in the amount of chlorophyll and statistically compared to identify any significant difference in temperature tolerance between these strains. If Leptolyngbya and Pseudophormidium are unable to grow in warmer temperatures then their ability to colonize BSCs may be affected and this will have unknown consequences to the microbial ecosystems they harbor as temperatures increase.http://opus.ipfw.edu/stu_symp2017/1036/thumbnail.jp

In this chapter, we argue that Walter White’s status as a fictional character in no way precludes our empathizing with him as another subject. Taking our cue from Edith Stein’s concept of empathy, we demonstrate that acts of memory are different from acts of empathy, and that how it is possible to empathize with fictional characters. This analysis is supplemented by Merleau-Ponty’s concept of a phenomenal body, which defines a body as a locus of possible action rather than a thing constituted of a certain material. We then provide an analysis of the potential conflict between empathic concern for (possibly evil) others and our own ethics; although it seems that great differences exist between individuals with respect to moral judgments, our similarities far exceed these differences

Best practice in wound care requires regular assessment of the wound to determine the progress of healing. The accuracy of this assessment is essential as clinicians determine treatment based on this information. Measurement of a wound’s dimensions and coloration are both critical aspects of this assessment. A reduction in wound size and healthy coloration are good indications of healing. The current standard of care for wound measurement involves using a ruler or measuring tape to measure the wound’s length, width, and depth at their greatest point. This manual method of measuring has limitations as it does not provide an accurate assessment of the surface area of the wound, and there is room for error between those performing the assessment. Traditional methods also inconvenience the patient with travel to a medical facility and consume significant hospital resources in the form of personnel and space. A system for remote monitoring of wounds by healthcare professionals via internet-enabled mobile devices equipped with stereoscopic cameras, has potential uses in the home, home healthcare, remote locations, extended care facilities and more. These mobile devices communicate with a web application to centralize patient imagery and analysis. Healthcare professionals will be able to remotely access the scaled images for examination, annotation, and historical comparison. With this information they can advise the patient without repeated office visits. Analysis such as color profiling in the assessment of the wound can guide treatment that could lead to better patient outcomes and satisfaction with their care. This project refines, extends, and integrates a prototype system that was developed by a senior capstone project team during the 2015-2016 academic year, with the primary goals of assisting healthcare professionals by minimizing opportunity for user error and increasing the effectiveness and fidelity of analysis. The effectiveness of stereoscopic 3D vision technology when applied to wound assessment will also undergo the beginning stages of user study. Additional features will include stereoscopic 3D vision display of wound imagery, color analysis, and the capability to upload stereoscopic images to the server directly from a newly developed mobile application
