Evensong “Knoxville: Summer of 1915”


Williams College is a private liberal arts college located in Williamstown, Massachusetts, USA. Founded in 1793, it is one of the oldest institutions of higher education in the United States. The college was established through a bequest of Colonel Ephraim Williams Jr., a war hero who died in the Battle of Lake George during the French and Indian War. In his will, Colonel Williams left funds for the establishment of a free school on the condition that it be located in Williamstown.

Lightning protection techniques for roof-top PV systems

Lightning protection techniques for roof-top PV systems

Narjes Fallah, et. al

Centre for Electromagnetic and Lightning Protection Research (CELP), Electrical & Electronic Engineering Department, Universiti Putra Malaysia, Malaysia

ABSTRACT: In this paper, the lightning protection requirements of a typical residential building have been discussed and techniques have been provided to protect the building from both direct and indirect damages of lightning, with special attention to the protection of PV panels placed on the roof. These techniques include the designing challenges and also the type of devices which can be used to reduce the surge current flow and magnetic field. It has been shown that for buildings with roof top PV systems only the avoidance of lightning attachment to unprotected parts of the building is not sufficient. Lightning currents passing through the lightning protection system may still affect the PV power system through inductive coupling. Hence strategic placement of PV systems and shielding of conducting systems wherever possible has been recommended. It has also been envisaged that the impact of lightning on PV systems is directly related to the isokeraunic level of the region and elevation of the building. Several recommendations have been proposed in designing the air termination system for a roof with PV panels in high isokeraunic regions. Finally the building integrated photo voltaic (BIPV) projects which are conducted in Malaysia have been evaluated..

Fountains

“Temple, Fountain and Cave in Sezincote Park” | Thomas Daniell (1819) | Yale Center for British Art

From time to time we break from our interest in lowering the cost of our “cities-within-cities” to enjoy the work of our colleagues responsible for seasonal ambience and public art.  We have a dedicated post that celebrates the accomplishments of our gardeners and horticultural staff.   Today we dedicate a post to campus fountains–a focal point for gathering and a place for personal reflection for which there is no price.

Alas, we find a quickening of standards developing organizations growing their footprint in the spaces around buildings now.  They used to confine the scopes of their standardization enterprises to the building envelope.  That day will soon be behind us as an energized cadre of water rights social justice workers, public safety, sustainability and energy conservation professionals descend upon campus fountains with prescriptive requirements for evaporation rates, bromine concentrations, training, certification and inspections.  In other words regulators and conformity functionaries will outnumber benefactors and fountain designers 1 million to 1.

We will deal with all that when the day comes.  For the moment, let’s just enjoy them.

We are happy to walk you through the relevant structural, water safety, plumbing and electrical issues any day at 11 AM EST during our daily standing online teleconferences.   Click on any image for author attribution, photo credit or other information.

Hot Dog University

The iconic American “street food” traces its origin to 19th century German immigrants who brought frankfurters from their homeland.

In the 1860s, the term “hot dog” emerged in reference to these sausages being sold in buns at street carts. The popularity of hot dogs soared during the late 19th and early 20th centuries particularly at baseball games where the hot dog is virtually synonymous.at the sport.

In many college towns push cart hot dog vendors may be welcomed and even embraced as part of the local food scene. They can add variety and convenience for students, faculty, and staff by offering affordable and quick meal options. These towns may have regulations and policies in place to support and accommodate such vendors.

The case against hot dogs as a food primarily revolves around health concerns and potential risks associated with their consumption. Some of the key arguments include:

Processed meat and additives: Hot dogs are often made from processed meats that can contain additives, preservatives, and high levels of sodium. These additives, such as nitrates and nitrites, have been linked to increased risks of certain health issues, including cancer and heart disease.

High in unhealthy fats: Hot dogs are typically high in saturated and trans fats, which can contribute to elevated cholesterol levels and increase the risk of cardiovascular diseases.

Potential for contamination: There have been instances of foodborne illnesses associated with hot dogs, such as outbreaks of bacterial contamination, including E. coli or Listeria monocytogenes. Improper handling, storage, or undercooking can increase the risk of such contamination.

Allergens and dietary restrictions: Hot dogs often contain common allergens like wheat, soy, and dairy. Additionally, they may not be suitable for individuals with dietary restrictions or preferences, such as vegetarians, vegans, or those following specific religious or cultural dietary guidelines.

Environmental impact: The production and consumption of hot dogs contribute to environmental concerns. The meat industry, including processed meat production, is associated with greenhouse gas emissions, land degradation, and water pollution.

These arguments against hot dogs do not necessarily apply to all hot dogs or to every individual. Moderation, choosing healthier options, and considering individual dietary needs and preferences can help mitigate some of the concerns associated with hot dog consumption.

Exploration of the Theory of Electric Shock Drowning

Exploration of the Theory of Electric Shock Drowning

Jesse Kotsch – Brandon Prussak – Michael Morse – James Kohl

University of San Diego

Abstract:  Drowning due to electric shock is theorized to occur when a current that is greater than the “let go” current passes through a body of water and conducts with the human body. Drowning would occur when the skeletal muscles contract and the victim can no longer swim. It is theorized that the likelihood of receiving a deadly shock in a freshwater environment (such as a lake) is higher than the likelihood in a saltwater environment (such as a marina). It is possible that due to the high conductivity of salt water, the current shunts around the individual, while in freshwater, where the conductivity of the water is lower than that of the human; a majority of the current will travel through the individual. The purpose of this research is to either validate or disprove these claims. To address this, we used Finite Element analysis in order to simulate a human swimming in a large body of water in which electric current has leaked from a 120V source. The conductivity of the water was varied from .005 S/m (pure water) up to 4.8 S/m (salt water) and the current density through a cross sectional area of the human was measured. With this research, we hope to educate swimmers on the best action to take if caught in such a situation.
