Spoon University was founded in 2013 by Sarah Adler and Mackenzie Barth, two Northwestern University students. Living off-campus, they struggled to cook and navigate local dining options, noticing a lack of food media tailored to college students. They launched a food-focused magazine and website at Northwestern, which quickly grew to over 100 student contributors.
The platform expanded to other campuses, driven by student interest, becoming a crowd-sourced food network for millennials. By 2015, it raised $2 million in funding and now operates chapters at over 200 campuses worldwide, offering recipes, reviews, and food-related content
Bert Askwith worked his way through college shuttling students to and from Detroit Metropolitan Airport until his graduation in 1931; when two semester tuition cost $300. With no student debt he founded and grew Campus Coach Lines that still provides the same services at many other US campuses. He donated part of his fortune to establish a cafe in the Undergraduate Library; which now serves an expanding and bewildering catalog of caffeine-based drinks found in educational settlements worldwide.

Any multi-story building requires inspection and maintenance of structural steel framework. The steel supports the building’s weight and resists environmental forces like wind and seismic activity. Over time, corrosion, fatigue cracks, or connection failures can weaken the structure, risking collapse. Inspections detect these issues early, while maintenance, like repainting or replacing damaged parts, preserves steel integrity. For student housing, occupant safety is critical, and compliance with building codes reduces liability risks. Neglecting these practices can lead to structural failure, endangering residents and causing costly repairs or legal issues. Regular upkeep ensures safe, long-lasting buildings.
During today’s session we examine the relevant standards with proposed revisions open for public comment. Use the login credentials at the upper right of our home page.
No single universal code or standard guarantees that buildings will never crack or fail structurally, as structural integrity depends on various factors like design, materials, construction quality, environmental conditions, and maintenance. However, several widely adopted codes and standards aim to minimize the risk of structural failure and ensure safety, durability, and serviceability. These provide guidelines for design, construction, and maintenance to prevent issues like cracking or catastrophic failure.
φ
Key Codes and Standards:
International Building Code (IBC): Widely used in the United States and other regions, the IBC sets minimum requirements for structural design, materials, and maintenance to ensure safety and performance. It references standards like ASCE 7 (Minimum Design Loads and Associated Criteria for Buildings and Other Structures) for load calculations (e.g., wind, seismic, snow).Maintenance provisions require regular inspections and repairs to address issues like cracking or deterioration.
ACI 318 (Building Code Requirements for Structural Concrete): Published by the American Concrete Institute this standard governs the design and construction of concrete structures.Includes requirements to control cracking (e.g., reinforcement detailing, concrete mix design) and ensure durability under environmental exposure.Maintenance guidelines recommend periodic inspections for cracks, spalling, or reinforcement corrosion.
AISC 360 (Specification for Structural Steel Buildings): Published by the American Institute of Steel Construction, this standard covers the design, fabrication, and erection of steel structures. Addresses fatigue, connection design, and corrosion protection to prevent structural failure. Maintenance involves inspecting for issues like weld imperfections or coating degradation.
The standards for delaying outdoor sports due to lightning are typically set by governing bodies such as sports leagues, associations, or organizations, as well as local weather authorities. These standards may vary depending on the specific sport, location, and level of play. However, some common guidelines for delaying outdoor sports due to lightning include:
Lightning Detection Systems: Many sports facilities are equipped with lightning detection systems that can track lightning activity in the area. These systems use sensors to detect lightning strikes and provide real-time information on the proximity and severity of the lightning threat. When lightning is detected within a certain radius of the sports facility, it can trigger a delay or suspension of outdoor sports activities.
Lightning Distance and Time Rules: A common rule of thumb used in outdoor sports is the “30-30” rule, which states that if the time between seeing lightning and hearing thunder is less than 30 seconds, outdoor activities should be suspended, and participants should seek shelter. The idea is that lightning can strike even when it is not raining, and thunder can indicate the proximity of lightning. Once the thunder is heard within 30 seconds of seeing lightning, the delay or suspension should be implemented.
Local Weather Authority Guidelines: Local weather authorities, such as the National Weather Service in the United States, may issue severe weather warnings that include lightning information. Sports organizations may follow these guidelines and suspend outdoor sports activities when severe weather warnings, including lightning, are issued for the area.
Sports-Specific Guidelines: Some sports may have specific guidelines for lightning delays or suspensions. For example, golf often follows a “Play Suspended” policy, where play is halted immediately when a siren or horn is sounded, and players are required to leave the course and seek shelter. Other sports may have specific rules regarding how long a delay should last, how players should be informed, and when play can resume.
It’s important to note that safety should always be the top priority when it comes to lightning and outdoor sports. Following established guidelines and seeking shelter when lightning is detected or severe weather warnings are issued can help protect participants from the dangers of lightning strikes.
Noteworthy: NFPA titles such as NFPA 780 and NFPA 70 Article 242 deal largely with wiring safety, informed by assuring a low-resistance path to earth (ground)
There are various lightning detection and monitoring devices available on the market that can help you stay safe during thunderstorms. Some of these devices can track the distance of lightning strikes and alert you when lightning is detected within a certain radius of your location. Some devices can also provide real-time updates on lightning strikes in your area, allowing you to make informed decisions about when to seek shelter.
Examples of such devices include personal lightning detectors, lightning alert systems, and weather stations that have lightning detection capabilities. It is important to note that these devices should not be solely relied upon for lightning safety and should be used in conjunction with other safety measures, such as seeking shelter indoors and avoiding open areas during thunderstorms.
Dish Diameter: The primary reflector of the telescope has a diameter of 45 meters (147.6 feet). This large size allows it to collect radio waves effectively.
Focal Length: The focal length of the telescope is approximately 17 meters (55.8 feet). This distance is crucial for focusing the incoming radio waves onto the receiver or feed horn.
Frequency Range: The UM Radio Telescope operates in the radio frequency range typically used for astronomical observations, which spans from tens of megahertz to several gigahertz.
Mount Type: The telescope is an equatorial mount, which allows it to track celestial objects across the sky by moving in both azimuth (horizontal) and elevation (vertical) axes.
Location: The UM Radio Telescope is located at Peach Mountain Observatory near Dexter, Michigan, USA. Its geographical coordinates are approximately 42.39°N latitude and 83.96°W longitude.
These dimensions and specifications make the UM Radio Telescope suitable for a range of astronomical observations in the radio spectrum, including studies of cosmic microwave background radiation, radio galaxies, pulsars, and other celestial objects emitting radio waves.
Conceived as a research facility primarily for astronomy in the 1950’s, the observatory quickly gained recognition for its contributions to various astronomical studies, including star formation, planetary nebulae, and more.
