One solution to this problem is the use of portable water filters. However, some water filters are too expensive or bulky to be economically sensible. A recent surge in additive manufacturing, involving the use of 3-D printers, has provided an alternative solution to this problem. This project’s primary objective is to test the usability of 3-D printed water filters. There are two major aspects to testing the filters: structural and performance. The filters will be designed with AutoCAD software and manufactured in a 3-D printer. Laboratory tests will be conducted to measure the performance of the water filters. The tests involve running manufactured wastewater with a known particle size distribution through the filters. Each filters’ performance is measured in three ways: net permeability, susceptibility to plugging and durability. The filters are expected to remove turbidity and Escherichia coli (E. coli) bacteria. Results show the current filters being tested can remove particles as small as 500 micrometers in size. This corresponds to conventional particle filtration (1 – 1,000 micrometers), but improvements in design are expected to screen out even smaller particles. Once an optimal design has been selected, new water filters will be manufactured from various polymers and modified with various surface coatings for specific contaminant removal. A survey has been conducted to explore peoples’ perceptions to the risks and benefits of 3-D printed water filters. It is important to gauge both professional and public responses to this new application. An individual may soon download a water filter design from an online website (or submit a personal design), have it manufactured at a local 3-D print vendor and then use the subsequent filter. The low-cost process will produce a small, portable and functional water filter.Item 3rd Annual Graduate Student Council Research Symposium (Abstract Booklet)(North Dakota State University, 2019-04-03) North Dakota State University. Graduate Student CouncilIn the abstract booklet, you will find information about the GSC team and the advisory board, and the abstracts to be presented. This is the first attempt to publish an abstract booklet for the GSC Research Symposium.Item Abnormal Leech Eyes in the Turtle Mountains(North Dakota State University, 2011-03-14)In 2009 and 2010, we surveyed the leeches in surface water within the Turtle mountain Band of Chippewa Reservation and in surrounding tribal land. One of the characteristics used to classify leeches is the number and arrangement of the eyes. During the identification process, it was observed some of the leeches have an abnormal number of eyesItem Batteryless, Leadless Pacemaker(North Dakota State University, 2016) Asif, SajidSajid Asif, 2016 North Dakota State University Three Minute Thesis Competition finalist, talks about his research on a batteryless, leadless pacemaker. Sajid is a graduate student in Electrical and Computer Engineering.Item Bodies, Spaces, and Powers: The 16th Annual Red River Women's Studies Conference (Program)(North Dakota State University, 2016-10-28)Conference program of the 16th Annual Red River Women's Studies Conference, held Friday, October 28, 2016, at the UND Gorecki Alumni Center (University of North Dakota).Item Changing the Landscape of Scholarly Communication: Digital Commons Pilot Project(North Dakota State University, 2009-10-08)Digital Commons is a project provided by the NDSU Libraries that collects, preserves, and distributes digital material (born or created) located at or produced by the NDSU community. It is part of an open access initiative fueled to increase the visibility of NDSU scholarship. The session will provide a brief overview of the project and explore how faculty, students, and staff can contribute to the ongoing development of new knowledge.Item Conference Schedule and Session Abstracts(North Dakota State University, 10/8/2009)Item Converting 3D Point Cloud Data into 2D Occupancy Grids suitable for Robot Applications(North Dakota State University, 2015) Huesman, JacobPoint clouds are a common data type in robotics applications. They allow a robot to “see” its environment. Unfortunately, its use for path planning is somewhat limited. There is just too much data for a robot to look through to calculate a path in a timely fashion. The objective of this research project is to create an algorithm that can take a 3D point cloud data set and convert it into a 2D occupancy grid, a much more common data type for navigation/path planning algorithms. The algorithm is named Cloud To Map. The development for this project proceeds according to the software development lifecycle. After extensive research, a list of requirements is developed. The algorithm is then designed and implemented. Subsequently, testing is done to ensure that the implementation satisfies the project requirements. During the testing phase, if any requirements are left unsatisfied, this process is then repeated. The research is ongoing. The first iteration of the algorithm is only capable of converting point clouds output by a specific application. Work is being done to allow it to convert point clouds from any source. While conversion algorithms like this one have been developed before, Cloud To Map has a broader range of applications. Upon completion, the project package will be published to ROS.org, which will make it available to developers around the world as a solution to the issue defined above.Item Cyberinfrastructure Conference 2011 E-postcard(North Dakota State University, 2011-03-04)Save-the-date card advertising the conferenceItem The Deep Underground Science and Engineering Laboratory (DUSEL): Opportunities to Engage and Inspire(North Dakota State University, 2011-02-28)The Sanford Center for Science Education (SCSE) is planned to be the education and outreach arm for the Deep Underground Science and Engineering Laboratory (DUSEL). This science education center will provide innovative programs, expand educational opportunities for a wide array of students, and generally enhance the efforts of Homestake DUSEL. Key to the vision is the weaving together of on-site and distance components. The underground science laboratory will be available to all through computer-simulated environments and access to authentic scientific data.Item Development of a State Health Information Exchange(North Dakota State University, 2011-03-02)Item Effect of coagulants in removing cyanotoxin-microcystinin drinking water treatment process(North Dakota State University, 2015) Xu, Yue; Roy, Dhriti; Khan, EakalakThe presence of cyanotoxins in source water is a worldwide problem. The most widespread cyanotoxin, called microcystins (MCs), produced from Microcystis Aeroginosa, can cause severe problems to the environment, animals and human health. A standard drinking water treatment process involves coagulation/flocculation process as primary treatment to remove cyanobacteria from source water. In coagulation/flocculation processes, a chemical coagulant is added to source water using rapid/slow mixing to facilitate bonding among particulates. As the process involves chemical and mechanical stress, cyanotoxin may get released to the drinking water. Coagulation/flocculation process can remove intact cyanobacteria effectively, however, study is limited to show the effect of coagulants in removing cyanotoxins during coagulation/flocculation. Our study would evaluate different types and concentration of coagulants to establish effective methods to remove cyanotoxins at the preliminary drinking water treatment. In this study, a jar test was conducted with microcystin-LR (MCLR) and microcystin-LA (MCLA) to show improved removal. A coagulation/flocculation process was used at laboratory bench scale. This study is important, as it establishes a method that would eliminate harmful cyanotoxins before they enter the secondary treatment process. The results would help drinking water facilities to remove cyanotoxins in the primary treatment where cyanobacteria and their toxins may be found in the source water.Item An environmental geology game for discovery-oriented science and mathematics education(North Dakota State University, 2011-02-25)A multi-user online educational game focused on earth and environmental science, experimentally validated to demonstrate learning gains in science and mathematics.Item Feminism, Politics, and the Limits of Diversity: The 10th Annual Red River Women's Studies Conference (Program)(North Dakota State University, 2010-10-01)Conference program of the 10th Annual Red River Women's Studies Conference, held Friday, October 1, 2010, at the UND Memorial Union (University of North Dakota).Item Fifth Annual Red River Valley Statistical Conference(North Dakota State University, 2015)North Dakota State University.
