    Get PDF
    In 2017, the Feeding America statistics reported 934,310 people in the state of Tennessee experience food insecurity (Feeding America, n.d.). It was also reported that 14.4% of the population (or 10,850 people) of Putnam County have at one point been food insecure. Food security and socioeconomic status of a household intersect with the performance of students attending college. External factors like anxiety over finances or worrying about food can have unknown implications on college completion. This review of literature poster will explore the current literature on food insecurity on college campuses and the implications it might have on students’ performance. The information for this poster was compiled from a total of eight research articles collected from Google Scholar and the Tennessee Tech University databases. Current research findings show a negative correlation between the rates of food insecurity with a number of factors like student academic status, financial status, and behavior. So far there is no consensus on the severity of food insecurity on college campuses, in fact no valid measuring tool exists to assess it. Future research is needed in order to create tools that can be used to implement programs on campuses. Feeding America (n.d.).

    Youtube for software security?: Youtube Videos Provide Pointers for Microservice Security

    Get PDF
    Microservice applications are defined as software applications, which include services that interact with one another but failure of one service does not impact the execution of another. Microservice oriented design has become a popular software application design paradigm among software companies, such as Uber, Netflix, and Amazon as well as small startup companies due to delivery speed, reliability and greater flexibility. However, any insecure coding pattern in the code while developing microservice applications can make the entire system vulnerable to hackers. The goal of the abstract is to help software developers in building secure microservice applications. We have conducted a qualitative analysis of 6 youtube videos on microservice design antipatterns and an empirical study on open source microservice repositories. We have observed insecure coding patterns in those microservice repositories. We have defined 9 categories each with an associated pattern namely HTTP without TLS, authentication vs authorization, hard coded secret, weak encryption algorithm, use of default ports, violation of least privilege principle, insufficient logging, poor orchestration layer configuration, API service sharing and distributed deadlock. We advocate for future research that will create a taxonomy of insecure coding patterns so that developers can find and resolve insecure coding patterns during code review

    Potential preservation of skin and intervertebral discs in a juvenile dinosaur (Edmontosaurus)

    No full text
    Soft tissue preservation in dinosaur fossils is relatively rare although a few examples have been found (Davis, 2014). We recovered a juvenile hadrosaur from the Hell Creek Formation of Montana with both skin impressions and potential preservation of intervertebral disks. Thin sections across original skin impressions have a dark, apparently organic rich, carbonaceous layer where skin would have been present in the original animal. This strongly suggests that the soft tissue was mineralized and preserved. However, we were unable to optically image cell boundaries similar to those figured by Manning, et al, (2009) that might demonstrate the presence of mineral cements that might outline the original cell boundaries. Apparently, the tissues in our hadrosaur were too decomposed to preserve such fine detail.Thin sections of the disks that occur between vertebrae are composed of fine-grained sandstone, which filled in the spaces between the vertebrae. Although this is a process that is not completely understood, it is clear that the skeleton lacks the presence of mineralized cartilage. The dark colored spots in the disks may, however, represent bits of cartilage material that has largely decomposed into carbonaceous material.Of the three types of preservation of dinosaurs suggested by Schweitzer (2012) our specimens has definite preserved impressions, possible compressions, but so far we have been unable to demonstrate preservation of three dimensional permineralized tissue

    Teachers’ Views on Flexible Seating in 2nd Grade

    No full text
    In this interpretive qualitative case study, I observed, interviewed, and collected documents from three 2nd grade teachers at a suburban Tennessee school in order to provide insight into teachers’ use of flexible seating, and the way the seating arrangement impacts their classroom management and instruction. Theories, such as Glasser’s choice theory, proclaim that student success is enhanced when students share classroom responsibilities and make decisions about their own learning and behavior. Flexible seating is said to empower the child with some degree of control over their learning environment, while still enabling teachers to retain the role of classroom manager

    Biodiesel yield based on the different oil composition and mixture ratio

    No full text
    Biodiesel is a renewable resource that can be grown quite literally from the ground up. It is a form of diesel that is derived from the transesterification of fatty acids within the oils of plant or animal-based products. These oils have a unique structure that could be varied owing to many factors; temperature, pressure, water, etc. This research looked into the justification for different molar ratio 4:1, 6:1, and 8:1. Owing to the composition and structure of the oils needed to achieve a better yield. Waste Vegetable oil mixed with methanol in proportions of 23.66 grams of lye in the methanol for every subsequent gallon of waste vegetable oil. Results showed that at high fatty Acid Value, the catalyst amount needs to be adjusted with operating temperature in the range of 60- 70 0c to produce yields up to 92-96%. While many forms of raw oil can be used in the production of biodiesel batches, the choice of modification/improvement on the process must be backed by proper storage measures. The oil chosen for this research was based on the reactive properties and fatty acid chains of waste vegetable oils. The sequences of production has minimal human involvement with support from the Raspberry Pi 3 software which signals different operational commands for producing biodiesel by activating a series of valves, pumps, and temperature devices in order to control liquid flow into & out of different reaction tanks

    *WINNER* Modeling a Photocatalytic Reactor: Water Contaminant Degradation, Energy Production, and the Radiation Field

    No full text
    As the amount of human and industrial waste in the environment increases, the need for more effective and efficient water treatment methods is higher than ever. Current wastewater treatment processes have been found to be ineffective against a growing number of contaminants, including pharmaceutical compounds. Coupled with the necessity of pharmaceutical-free water, energy sources that are easily produced, affordable, and environmentally-friendly are a growing societal need. This project will employ two methods of approach to address the issues of pharmaceutical degradation and energy production. The first method will employ thin-film photocatalysis to achieve simultaneous contaminant degradation and hydrogen gas production as an energy source. The second method will utilize the development of a mathematical model of the reactor system, intended for future use as an upscaling mechanism to be used in wastewater treatment facilities

    The Role of Strong Hydrogen Bonds in Humic Acid

    No full text
    With the growing demand for drinking water, purification processes must be operating at maximum efficiency. It has been found that humic acids are useful in removing toxic metals, oil, liquid organics, and other suspended matter; however, during the purification process these molecules have been found to aggregate and potentially create fouling and other undesirable effects. This can result in less efficient purification systems which is why it is important to understand humic acid molecules on a molecular level. It is currently thought that these molecules contain strong hydrogen bonds, which is assumed to be the driving force of aggregation. In this project, the goal is to achieve an understanding of the role of strong hydrogen bonds in the supramolecular assembly on a fundamental level and provide insight into the evolution of humic acids structure and its dependence on shear stress

    *WINNER* Historical and Sociological Impacts of the Duck River on Maury County, Tennessee Communities

    No full text
    Global communities and cultures have been greatly shaped because of river systems. Rivers often shape several aspects of a community, some of which include settling patterns and industry. The Duck River has been shaping the lives of those living in Maury County for centuries. I conducted my research by examining how the Duck River has impacted three groups of people in Maury County. I examined the Duck River's sociological and historical impact on Native Americans, early European settlers, and modern day Maury Countians. I found that Native Americans who lived in the Maury County area prior to European settlement used the Duck River for fishing. The Duck River was highly respected by the indigenous population living in the area. Early Europeans in Maury County settled near the Duck River so they could take advantage of the Duck River's resources. Early European settlers built dams, mills, and shops along the Duck River. The Duck River was also used as a way to transport materials and goods. Today, the Duck River is the water source for those living in Maury County. The Duck River is also used for recreational purposes like canoeing and kayaking

    Current Professional Opinions on the Use of Child Restraint

    The use of child restraint in the medical setting is an essential topic of discussion. This topic is important because, not only are there physical and psychological risks for the child who is being restrained, but there are also critical ethical implications for medical staff that come along with the use of restraint. While the use of restraint may be unavoidable at times, therapeutic holding should always be used if at all possible due to the risk factors presented by the use of restraint. It is important to note that restraint should only be used when the health and safety of the child and/or staff is in question. When searching the literature, I used the key terms “child restraint” and “therapeutic holding.” It is also imperative to understand the similarities and differences between these two terms. Overall, there is a time and place for child restraint in the medical setting, but there must be communication and training with medical staff to understand the purpose and the appropriateness of its use, as well as the alternatives

    Presenting Students with Buffer Overflow Vulnerability

    No full text
    The goal of this project is to analyze how students can apply and adapt low level computer science principles, specifically in exploiting buffer overflows in Linux operating system. Students are given an executable file with a known buffer overflow vulnerability, and a source code file with a known vulnerability. Each student must examine the memory addresses of their executable in order to calculate a payload, which will overwrite the return address in stack and will jump in a “secret” function. Each student is provided with a compiled binary executable file with a minor change of the displayed message. Once students have successfully demonstrated the buffer overflow exploit, they will need to find a protection mechanism against the buffer overflow attack they just developed. The way that students approach the problem of attacking software, as well as their strategies regarding to protect against buffer overflow attacks, will be studied in order to evaluate students’ active learning skills
