College students create the ultimate hangover cure

Two Yale University seniors have created a product they believe will cure what ails their peers — and many others: hangovers.

Margaret Morse and Liam McClintock wanted a supplement that would allow them to have fun on a night out, but would not impede on being able to work the next morning.

What causes hangovers to begin with? Morse, a molecular cellular and developmental biology major, told local news outlet WTNH, “There’s an acetaldehyde build up. There is a vitamin and electrolyte loss. There is a glutamine rebound and there are immunological disturbances.”

Their proposed solution is SunUp, a powdered citrus-flavored supplement filled with vitamins and nutrients.

“This is a powder that you take before you start drinking and it helps your liver deal with the stress you’re putting it under when you drink,” McClintock told WTNH. According to the New Haven Register, one would drink SunUp in a glass of water around an hour before they start drinking.  While one might believe dehydration is the cause of hangovers, SunUp’s website explains that it is actually a symptom. “These two phenomena are concurrent because of the diuretic effects of alcohol, but dehydration does not cause the actual hangover feeling,” says the site’s FAQ.  SunUp instead focuses on combating four root causes of a hangover: acetaldehyde building, vitamin and electrolyte loss, glutamine rebound and immunological disturbances.

“It’s intended for productive workers,” McClintock told WTNH. “Like ourselves who like to have a social life, like to go out and have a couple of drinks but also need to be productive the next day and get up and have work to do.”

Morse and McClintock have received positive feedback from fellow students and the Yale community. They’ve brought it to a pharmaceutical company, and it could be available in April. SunUp will retail for $5; if you want to pre-order, you can purchase through the company’s Indiegogo page.

Dynamic Exit Signs

Dynamic exit signs are a type of emergency exit signage that uses active illumination and changes in light to draw attention to the nearest exit in case of an emergency. Unlike traditional exit signs that use static or passive lighting to indicate exit locations, dynamic exit signs incorporate lighting systems that respond to specific environmental conditions or power outages, which can help to guide people to safety more efficiently.

There are several types of dynamic exit signs, including:

  • Photoluminescent exit signs: These signs absorb and store light energy from ambient sources, such as room lighting or sunlight, and then glow brightly in the dark when the power goes out.
  • LED exit signs: These signs use light-emitting diodes (LEDs) to create animated or flashing signs that can better catch people’s attention.
  • Electroluminescent exit signs: These signs use electrically charged phosphors to produce a bright, uniform light source that can be more visible in low-light or smoke-filled environments.

Overall, dynamic exit signs are designed to enhance visibility and guide people to safety during an emergency, and they can be an important part of an overall emergency preparedness plan.

Localized fire ignition hazard in branch circuits, cords and connected equipment

Electrical Engineering Department, Sapienza Università di Roma

Abstract.  In electrical power systems, the fire ignition can be originated by incident energy of faults. Faults involve overheating, arcing and burning for all the wiring exposed to mechanical damage and other insulation stresses especially wiring connected by flexible cords and cables. The mechanical damage of the stranded bare conductors can degrade the effective sizing of the total cross section, causing anomalous conditions of local overcurrent. To highlight the local incident energy in case of fault, the parameters steady current and transient current densities can assist in analyzing the event. The conductors size reduction, degrading locally the thermal withstand capability, makes ineffective the protection coordination amplifying the anomalous effect of current no detectable adequately by overcurrent protective devices. The faulted cords remain so energized and present electric shock and fire hazards. Generally and especially in strategic buildings as hospitals, preventing ignition is better than promptly extinguishing. An efficient protection can be achieved by integration of active and passive techniques : by adoption of the special device Arc-fault Circuit Interrupter (AFCI) that recognize the arcing; by wiring the circuits, particularly extension cords, with Ground-Fault-Forced Cables, GFFCs, that convert faults into ground faults easily protected by ground fault protective devices (GFPDs).
