Grandma’s Chicken Soup
WRITTEN BY Kalani Simpson PUBLISHED May 25, 2021
Ingredients:
- 1 5- to 6-pound stewing hen or baking chicken
- 1 package of chicken wings
- 3 large onions
- 1 large sweet potato
- 3 parsnips
- 2 turnips
- 11 to 12 large carrots
- 5 to 6 celery stems
- 1 bunch of parsley
- Salt and pepper to taste
Directions:
- Clean the chicken, put it in a large pot and cover it with cold water. Bring the water to boil.
- Add the chicken wings, onions, sweet potato, parsnips, turnips and carrots. Boil about 1 and a half hours. Remove fat from the surface as it accumulates.
- Add the parsley and celery. Cook the mixture about 45 min. longer.
- Remove the chicken. The chicken is not used further for the soup. (The meat makes excellent chicken parmesan.)
- Put the vegetables in a food processor until they are chopped fine or pass through a strainer. Both were performed in the present study.
- Add salt and pepper to taste.
(Note: This soup freezes well.) Matzo balls were prepared according to the recipe on the back of the box of matzo meal (Manischewitz).

Today we break down consultations on titles relevant to the technology and management of the real assets of education communities in the United States specifically; but with sensitivity to the global education markets where thousands of like-minded organizations also provide credentialing, instruction, research, a home for local fine arts and sport.
We steer away from broad policy issues and steer toward technical specifics of public consultations presented by national member bodies of the International Electrotechnical Commission, the International Organization for Standardization, the International Telecommunications Union and the American National Standards Institute. If there is a likelihood that the titles published by these workgroups will be incorporated by reference into public safety or sustainability legislation; or integrated into the cost structure of education communities in any other way, we will listen carefully and contribute meaningfully where we can.
Vienna Convention on Diplomatic Relations | 1961
| “Even apart from the instability due to speculation, there is the instability due to the characteristic of human nature that a large proportion of our positive activities depend on spontaneous optimism rather than on a mathematical expectation, whether moral or hedonistic or economic. Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as the result of animal spirits — a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities. Enterprise only pretends to itself to be mainly actuated by the statements in its own prospectus, however candid and sincere that prospectus may be. Only a little more than an expedition to the South Pole is it based on an exact calculation of benefits to come. Thus if the animal spirits are dimmed and the spontaneous optimism falters, leaving us to depend on nothing but a mathematical expectation, enterprise will fade and die; — though fears of loss may have a basis no more reasonable than hopes of profit had before.”

Such a program is very simple in most programming languages (such as Python and Javascript) and is often used to illustrate the basic syntax of a programming language. It is often the first program written by people learning to code. It can also be used as a sanity test to make sure that a computer language is correctly installed, and that the operator understands how to use it.
Technical Barriers to Trade
World According to Marco Polo
We track action in international administrative procedures that affect the safety and sustainability agenda of the education facility industry. From time to time we find product purchasing contracts that contain “boilerplate” requiring conformity to applicable regulations found in the Agreement on Technical Barriers to Trade (TBT). Common examples are found in contracts for the acquisition of information technology and specialty laboratory equipment.
The World Trade Organization TBT Agreement obliges all Parties to maintain an inquiry point that is able to answer questions from interested parties and other WTO Members regarding technical regulations, standards developed by government bodies, and conformity assessment procedures, as well as provide relevant documents. The TBT Agreement also requires that WTO Members notify the WTO of proposed technical regulations and conformity assessment procedures so interested parties can become acquainted with them and have an opportunity to submit written comments.
Technical Barriers to Trade Information Management System
The inquiry point and notification authority for the United States is operated by the National Institute of Standards and Technology an agency within the U.S. Department of Commerce. We provide a link here for the convenience of faculty, specifiers and purchasing professionals.

Eurocodes
CLICK ON IMAGE TO LAUNCH INTERACTIVE MAP
The Eurocodes are ten European standards (EN; harmonised technical rules) specifying how structural design should be conducted within the European Union. These were developed by the European Committee for Standardization upon the request of the European Commission. The purpose of the Eurocodes is to provide:
- A means to prove compliance with the requirements for mechanical strength and stability and safety in case of fire established by European Union law.[2]
- A basis for construction and engineering contract specifications.
- A framework for creating harmonized technical specifications for building products (CE mark).
Since March 2010 the Eurocodes are mandatory for the specification of European public works and are intended to become the de facto standard for the private sector. The Eurocodes therefore replace the existing national building codes published by national standard bodies, although many countries have had a period of co-existence. Additionally, each country is expected to issue a National Annex to the Eurocodes which will need referencing for a particular country (e.g. The UK National Annex). At present, take-up of Eurocodes is slow on private sector projects and existing national codes are still widely used by engineers.
Eurocodes appear routinely on the standing agendas of several of our daily colloquia, among them the AEDificare, Elevator & Lift and Hello World! colloquia. See our CALENDAR for the next online meeting; open to everyone.

Design Standard Readability
Fry readability formula

Department of Industrial and Operations Engineering, University of Michigan, Ann Arbor, MI, USA
Abstract. Research problem: Readability equations are widely used to compute how well readers will be able to understand written materials. Those equations were usually developed for nontechnical materials, namely, textbooks for elementary, middle, and high schools. This study examines to what extent computerized readability predictions are consistent for highly technical material – selected Society of Automotive Engineers (SAE) and International Standards Organization (ISO) Recommended Practices and Standards relating to driver interfaces. Literature review: A review of original sources of readability equations revealed a lack of specific criteria in counting various punctuation and text elements, leading to inconsistent readability scores. Few studies on the reliability of readability equations have identified this problem, and even fewer have systematically investigated the extent of the problem and the reasons why it occurs. Research questions:
(1) Do the most commonly used equations give identical readability scores?
(2) How do the scores for each readability equation vary with readability tools?
(3) If there are differences between readability tools, why do they occur?
(4) How does the score vary with the length of passage examined?
Method: Passages of varying lengths from 12 selected SAE and ISO Recommended Practices and Standards were examined using five readability equations (Flesch-Kincaid Grade Level, Gunning Fog Index, SMOG Index, Coleman-Liau Index, and Automated Readability Index) implemented five ways (four online readability tools and Microsoft Word 2013 for Windows). In addition, short test passages of text were used to understand how different readability tools counted text elements, such as words and sentences. Results and conclusions: The mean readability scores of the passages from those 12 SAE and ISO Recommended Practices and Standards ranged from the 10th grade reading level to about 15th. The mean grade reading levels computed across the websites were: Flesch-Kincaid 12.8, Gunning Fog 15.1 SMOG 12.6, Coleman-Liau 13.7, and Automated Readability Index 12.3. Readability score estimates became more consistent as the length of the passage examined increased, with no noteworthy improvements beyond 900 words. Among the five readability tools, scores typically differed by two grade levels, but the scores should have been the same. These differences were due to how compound and hyphenated words, slashes, numbers, abbreviations and acronyms, and URLs were counted, as well other punctuation and text elements. These differences occurred because the sources for these equations often did not specify how to score various punctuation and text elements. Of the tools examined, the authors recommend Microsoft Word 2013 for Windows if the Flesch-Kincaid Grade Level is required.

Wires
Ampere current flows through copper or aluminum conductor due to the movement of free electrons in response to an applied electric field of varying voltages. Each copper or aluminum contributes one free electron to the electron sea, creating a vast reservoir of mobile charge carriers. When a potential difference (voltage) is applied across the ends of the conductor, an electric field is established within the conductor. This field exerts a force on the free electrons, causing them to move in the direction of the electric field. The resulting current flow can be transformed into different forms depending on the nature of the device.
Heating: When current flows through a resistor, it encounters resistance, which causes the resistor to heat up. This is the principle behind electric heaters, toasters, and incandescent light bulbs.
Mechanical Work: Current flowing through an electric motor creates a magnetic field, which interacts with the magnetic field of the motor’s permanent magnets or electromagnets. This interaction generates a mechanical force, causing the motor to rotate. Thus, electrical energy is converted into mechanical energy; including sound.
Light: In an incandescent light bulb, a filament heats up ( a quantum phenomena) due to the current passing through it. This is an example of electrical energy being converted into light energy; including the chemical energy through light emitting diodes
Today we dwell on how conductors are specified and installed in building premise wiring systems primarily; with some attention to paths designed to carry current flowing through unwanted paths (ground faults, phase imbalance, etc). In the time we have we will review the present state of the best practice literature developed by the organizations listed below:

Municipalities usually have specific land use or zoning considerations to accommodate the unique needs and characteristics of college towns:
- Mixed-Use Zoning: Cities with colleges and universities often employ mixed-use zoning strategies to encourage a vibrant and diverse urban environment. This zoning approach allows for a combination of residential, commercial, and institutional uses within the same area, fostering a sense of community and facilitating interactions between students, faculty, and residents.
- Height and Density Restrictions: Due to the presence of educational institutions, cities may have specific regulations on building height and density to ensure compatibility with the surrounding neighborhoods and maintain the character of the area. These restrictions help balance the need for development with the preservation of the existing urban fabric.
- Student Housing: Cities with colleges and universities may have regulations or guidelines for student housing to ensure an adequate supply of affordable and safe accommodations for students. This can
include requirements for minimum bedroom sizes, occupancy limits, and proximity to campus. - Parking and Transportation: Given the concentration of students, faculty, and staff, parking and transportation considerations are crucial. Cities may require educational institutions to provide parking facilities or implement transportation demand management strategies, such as promoting public transit use, cycling infrastructure, and pedestrian-friendly designs.
- Community Engagement: Some cities encourage colleges and universities to engage with the local community through formalized agreements or community benefit plans. These may include commitments to support local businesses, contribute to neighborhood improvement projects, or provide educational and cultural resources to residents.

- Reed v. Town of Gilbert (2015): This Supreme Court case involved a challenge to the town of Gilbert, Arizona’s sign code, which regulated the size, location, and duration of signs based on their content. The court held that the sign code was a content-based restriction on speech and therefore subject to strict scrutiny.
- City of Ladue v. Gilleo (1994): In this Supreme Court case, the court struck down a municipal ordinance that banned the display of signs on residential property, except for signs that fell within specific exemptions. The court held that the ban was an unconstitutional restriction on the freedom of speech.
- Metromedia, Inc. v. San Diego (1981): This Supreme Court case involved a challenge to a San Diego ordinance that banned off-premises advertising signs while allowing on-premises signs. The court held that the ordinance was an unconstitutional restriction on free speech, as it discriminated against certain types of speech.
- City of Ladue v. Center for the Study of Responsive Law, Inc. (1980): In this Supreme Court case, the court upheld a municipal ordinance that prohibited the display of signs on public property, but only if the signs were posted for longer than 10 days. The court held that the ordinance was a valid time, place, and manner restriction on speech.
- City of Boerne v. Flores (1997): This Supreme Court case involved a challenge to a municipal sign code that regulated the size, location, and content of signs in the city. The court held that the sign code violated the Religious Freedom Restoration Act, as it burdened the exercise of religion without a compelling government interest.

Meeting Notes in red
Loss of electric power and internet service happens more frequently and poses at least an equal — if not greater threat — to public safety. So why does neither the National Electrical Code or the National Electrical Safety Code integrate reliability into their core requirements? Reliability requirements appear in a network of related documents, either referenced, or incorporated by reference; sometimes automatically, sometimes not.
NESC Main Committee Membership: Page xii
Apart from the IEEE as the accredited standards developer, there are no “pure non-government user-interests” on this committee; although ANSI’s Essential Requirements for balance of interests provides highly nuanced interpretation. The Classifications on Page xiii represents due diligence on meeting balance of interest requirements.
In our case, we are one of many large universities that usually own district energy plants that both generate and purchase generate electric power (as sometimes provide var support to utilities when necessary; as during the August 2003 North American outage). For University of Michigan, for example, has about 20 service points at 4.8 – 120 kV. Its Central Power Plant is the largest cogeneration plant on the DTE system.

Absence of internet service is at least as much a hazard, and more frequent, than downed wires. Is there a standards solution? Consideration of interoperability of internet service power supported on utility poles should track in the next revision.
