Ice Cream at the Rock

Michigan Central

The invention of ice cream, as we know it today, is a product of historical evolution, and there isn’t a single individual credited with its creation. Various cultures and civilizations throughout history have contributed to the development of frozen treats resembling ice cream.

One of the earliest records of frozen desserts can be traced back to ancient China, where people enjoyed a frozen mixture of milk and rice around 200 BC. Similarly, ancient Persians and Arabs had a tradition of mixing fruit juices with snow or ice to create refreshing treats.

In Europe, frozen desserts gained popularity in the 17th and 18th centuries, and it was during this time that the more modern version of ice cream, made with sweetened milk or cream, began to take shape. During this period, ice cream became more widely accessible and enjoyed by the nobility and upper classes.

MSU Infrastructure Planning and Facilities

To produce ice cream on a commercial scale, several key pieces of infrastructure and equipment are necessary. The specific requirements may vary depending on the production capacity and the type of ice cream being produced, but the basic infrastructure typically includes:

  1. Manufacturing Facility: A dedicated space or building is needed to house all the production equipment and storage facilities. The facility should comply with local health and safety regulations and be designed to maintain the required temperature and hygiene standards.
  2. Mixing and Blending Equipment: Industrial-scale mixers and blending machines are used to mix ingredients like milk, cream, sugar, stabilizers, emulsifiers, and flavorings. These machines ensure that the mixture is homogenized and consistent.
  3. Pasteurization Equipment: To ensure product safety and extend shelf life, ice cream mix needs to be pasteurized. Pasteurization equipment heats the mixture to a specific temperature and then rapidly cools it to destroy harmful microorganisms.
  4. Homogenizers: Homogenizers help break down fat molecules in the ice cream mix to create a smoother and creamier texture.
  5. Aging Vats: The ice cream mix is aged at a controlled temperature for a specific period, which allows the ingredients to fully blend and improves the ice cream’s texture.
  6. Freezers: Continuous freezers or batch freezers are used to freeze the ice cream mix while incorporating air to create the desired overrun (the amount of air in the final product). Continuous freezers are more commonly used in large-scale production, while batch freezers are suitable for smaller batches.
  7. Hardening and Storage Room: Once the ice cream is frozen, it needs to be hardened at a lower temperature to achieve the desired texture. Storage rooms are used to store finished ice cream at the appropriate temperature until distribution.
  8. Packaging Equipment: Equipment for filling and packaging the ice cream into various containers, such as cartons, tubs, or cones.
  9. Quality Control and Laboratory Facilities: A dedicated area for quality control testing, where ice cream samples are analyzed for consistency, flavor, and other characteristics.
  10. Cleaning and Sanitation Systems: Proper cleaning and sanitation systems are essential to maintain hygiene and prevent contamination.
  11. Utilities: Adequate water supply, electrical power, and refrigeration capacity are critical for ice cream production.

USA Swimming and the National Collegiate Athletic Association Swimming are two distinct organizations that oversee different aspects of competitive swimming in the United States. USA Swimming governs competitive swimming in the United States across all age groups and skill levels, while NCAA Swimming specifically focuses on collegiate-level swimming and diving competitions within the NCAA framework. Both organizations play crucial roles in the development and promotion of swimming in the United States.

Governing Body:

USA Swimming is the national governing body for the sport of swimming in the United States. It is responsible for overseeing competitive swimming at all levels, from grassroots programs to elite national and international competitions.
NCAA Swimming: NCAA Swimming is part of the National Collegiate Athletic Association (NCAA), which governs intercollegiate sports in the United States. NCAA Swimming specifically deals with collegiate-level swimming competitions among universities and colleges.

Scope:

USA Swimming is responsible for organizing and regulating competitive swimming for all age groups and skill levels, from youth swimmers to Masters swimmers (adults). It oversees swim clubs, hosts competitions, and develops national teams for international events.
NCAA Swimming: NCAA Swimming focuses exclusively on college-level swimming and diving competitions. It sets the rules and guidelines for swimming and diving programs at NCAA member institutions.

Membership:

Individuals, swim clubs, and teams can become members of USA Swimming, allowing them to participate in USA Swimming-sanctioned events, access coaching resources, and benefit from the organization’s development programs.
NCAA Swimming: NCAA Swimming is composed of collegiate athletes who compete for their respective universities and colleges. Athletes are typically student-athletes who represent their schools in NCAA-sanctioned competitions.

Competition Format:

USA Swimming hosts a wide range of competitions, including local, regional, and national meets, as well as Olympic Trials and international events. Swimmers compete as individuals, representing their swim clubs or teams.
NCAA Swimming: NCAA Swimming primarily consists of dual meets, invitational meets, and conference championships at the collegiate level. Swimmers represent their respective universities or colleges, earning points for their teams in dual meets and competing for conference and national titles.

Scholarships:

USA Swimming itself does not offer scholarships. Scholarships for competitive swimmers are typically awarded by colleges and universities based on an athlete’s performance and potential.
NCAA Swimming: NCAA member institutions offer scholarships to talented student-athletes in various sports, including swimming. These scholarships can cover tuition, room, board, and other expenses, making NCAA swimming an avenue for athletes to receive financial support for their education.

 


Water and Electricity

Supporting swimming pools with electricity involves various essential functions such as filtration, heating, lighting, and sanitation. Ensuring safety and energy efficiency is crucial, and pool owners can take steps to minimize electricity costs and environmental impact. Key points:

Filtration and Circulation: Swimming pools rely on electric pumps to circulate water through filters, removing debris and maintaining water quality.

Heating: Electric heaters or heat pumps are used to regulate water temperature for comfort, especially in colder seasons.

Lighting: Underwater and pool area lighting enhance safety and aesthetics, typically powered by electricity.

Chlorination and Sanitation: Electric chlorinators or ozone generators help maintain water cleanliness and hygiene.

Automation: Electric control systems enable pool owners to manage filtration, heating, and lighting remotely for convenience and energy efficiency.

Energy Efficiency: Pool owners can invest in energy-efficient equipment, like variable-speed pumps and LED lighting, to reduce electricity consumption and operating costs.

Operations and Maintenance: Regular electrical maintenance ensures safe and reliable pool operation, preventing electrical faults and hazards.  The electricity cost for pool operation can be significant, so pool owners should consider energy-efficient practices and equipment to reduce expenses.

We sweep through the world’s three major time zones; updating our understanding of the literature at the technical foundation of education community safety and sustainability in those time zones 24 times per day. We generally eschew “over-coding” web pages to sustain speed, revision cadence and richness of content as peak priority.  We do not provide a search facility because of copyrights of publishers and time sensitivity of almost everything we do.

Cognitive Science: An Introduction to the Study of Mind

Our daily colloquia are typically doing sessions; with non-USA titles receiving priority until 16:00 UTC and all other titles thereafter.  We assume policy objectives are established (Safer-Simpler-Lower-Cost, Longer-Lasting).   Because we necessarily get into the weeds, and because much of the content is time-sensitive and copyright protected, we usually schedule a separate time slot to hammer on technical specifics so that our response to consultations are meaningful and contribute to the goals of the standards developing organization and to the goals of stewards of education community real assets.

1. Leviathan.  We track noteworthy legislative proposals in the United States 118th Congress.  Not many deal specifically with education community real assets since the relevant legislation is already under administrative control of various Executive Branch Departments such as the Department of Education.

We do not advocate in legislative activity at any level.   We respond to public consultations but there it ends.

We track federal legislative action because it provides a stroboscopic view of the moment — the “national conversation”– in communities that are simultaneously a business and a culture.  Even though more than 90 percent of such proposals are at the mercy of the party leadership the process does enlighten the strengths and weakness of a governance system run entirely through the counties on the periphery of Washington D.C.  It is impossible to solve technical problems in facilities without sensitivity to the zietgeist that has accelerated in education communities everywhere.

There are several specific problems that swimming pool overhead lighting aims to solve:

  1. Visibility: Swimming pool overhead lighting is designed to improve visibility in and around the pool. This is important for safety reasons, as it helps swimmers see where they are going and avoid obstacles or hazards.
  2. Aesthetics: Overhead lighting can enhance the appearance of the swimming pool by creating a visually appealing atmosphere. This is especially important for commercial pools where the aesthetics can be an important factor in attracting customers.
  3. Functionality: Overhead lighting can provide additional functionality by allowing the pool to be used during evening hours or in low light conditions. This can increase the usability of the pool and make it more appealing to users.
  4. Energy efficiency: Modern overhead pool lighting solutions are designed to be energy-efficient, reducing the overall energy consumption and operating costs of the pool.
  5. Longevity: Overhead pool lighting must be designed to withstand exposure to water, chlorine, and other harsh chemicals, as well as exposure to the elements. The lighting system must be durable and reliable to ensure longevity and prevent costly repairs or replacements.

Overall, swimming pool overhead lighting is an important component of a safe, functional, and visually appealing pool. It provides illumination for visibility, enhances aesthetics, and improves functionality, while also being energy-efficient and durable.

After athletic arena life safety obligations are met (governed legally by NFPA 70, NFPA 101, NFPA 110,  the International Building Code and possibly other state adaptations of those consensus documents incorporated by reference into public safety law) business objective standards may come into play. For almost all athletic facilities,  the consensus documents of the Illumination Engineering Society[1], the Institute of Electrical and Electronic Engineers[2][3] provide the first principles for life safety.  For business purposes, the documents distributed by the National Collegiate Athletic Association inform the standard of care for individual athletic arenas so that swiftly moving media production companies have some consistency in power sources and illumination as they move from site to site.  Sometimes concepts to meet both life safety and business objectives merge.

During water sport season the document linked below provides information to illumination designers and facility managers:

NCAA Best Lighting Practices

Athletic programs are a significant source of revenue and form a large part of the foundation of the brand identity of most educational institutions in the United States.   We focus primarily upon the technology standards that govern the safety, performance and sustainability of these enterprises.  We collaborate very closely with the IEEE Education & Healthcare Facilities Committee where subject matter experts in electrical power systems meet 4 times each month in the Americas and Europe.

See our CALENDAR for our next colloquium on Sport facility codes and standards  We typically walk through the safety and sustainability concepts in play; identify commenting opportunities; and find user-interest “champions” on the technical committees who have a similar goal in lowering #TotalCostofOwnership.

NARUC Position on NFPA (NEC) and IEEE (NESC) Harmonization

The standard of care for electrical safety at high and low voltage is set by both the NEC and the NESC. There are gaps, however (or, at best “gray areas”) — the result of two technical cultures: utility power culture and building fire safety culture. There is also tradition. Local system conditions and local adaptation of regulations vary. Where there is a gap; the more rigorous requirement should govern safety of the public and workers.

The 2023 National Electrical Safety Code (NESC)– an IEEE title often mistaken for NFPA’s National Electrical Code (NEC) — was released for public use about six months ago; its normal 5-year revision cycle interrupted by the circumstances of the pandemic.   Compared with the copy cost of the NEC, the NESC is pricey, though appropriate for its target market — the electric utility industry.  Because the 2023 revision has not been effectively “field tested” almost all of the available support literature is, effectively, “sell sheets” for pay-for seminars and written by authors presenting themselves as experts for the battalions of litigators supporting the US utility industry.  Without the ability to sell the NESC to prospective “insiders” the NESC would not likely be commercial prospect for IEEE.   As the lawsuits and violations and conformance interests make their mark in the fullness of time; we shall see the 2023 NESC “at work”.

We collaborate closely with the IEEE Education & Healthcare Facilities Committee (IEEE E&H) to negotiate the standard of care for power security on the #SmartCampus  since many campus power systems are larger than publicly regulated utilities.  Even when they are smaller, the guidance in building the premise wiring system — whether the premise is within a building, outside the building (in which the entire geography of the campus footprint is the premise), is inspired by IEEE Standards Association administrated technical committees.

Northeast Community College | Norfolk, Nebraska

Today we begin a list of noteworthy changes to be understood in the next few Power colloquia.  See our CALENDAR for the next online meeting.

  1. New rules 190 through 195 cover photovoltaic generating stations.  Rule 116c adds an exception for short lengths of insulated power cables and short-circuit protection if the situation involves fewer than 1,000 volts.
  2. Rule 320B has been revised to clarify separations that apply to communications and supply in different conduit systems.
  3. Table 410-4 is based on the latest arc flash testing on live-front transformers.
  4. Rule 092A adds an exception allowing protection, control, and safety battery systems to not be grounded.
  5. Rules 234 B1, C1, D1 were revised to better present vertical and horizontal wind clearances, and to coordinate requirements with the new Table 234-7.
  6. Rule 120A was revised to provide correction factors for clearances on higher elevations.
  7. Table 253-1 has been revised to reduce the load factor for fiber-reinforced polymer components under wire tension—including dead ends—for Grade C construction.
  8. Rule 410A now requires a specific radio-frequency safety program for employees who might be exposed.
  9. In the Clearances section, as well as in the specification of the Grade of Construction in Table 242-1, the Code further clarifies the use of non-hazardous fiber optic cables as telecom providers continue to expand their networks.
  10. Revisions in the Strength & Loading sections include modified Rule 250C, which addresses extreme wind loading for overhead lines. Two wind maps are now provided instead of the previous single one. A map for Grade B, the highest grade of construction, with a Mean Recurrence Interval (MRI) of 100 years (corresponding to a one percent annual probability of occurrence) is provided in place of the previous 50–90-year MRI map. For Grade C construction, a separate 50-year MRI (two percent annual probability of occurrence) map is now provided. In the previous Code, a factor was applied to the 50–90-year MRI map for application to Grade C.
  11. Changes were also made to the method of determining the corresponding wind loads, consistent with the latest engineering practices as an example of a Code revision focused on public safety, the ground end of all anchor guys adjacent to regularly traveled pedestrian thoroughfares, such as sidewalks, and similar places where people can be found must include a substantial and conspicuous marker to help prevent accidents. The previous Code did not require the marking of every such anchor guy.
  12. Significant revisions were made in Section 14 covering batteries. Previous editions of the code were based on lead-acid technology and batteries only used for backup power. The 2023 Code incorporates the new battery technologies and addresses energy storage and backup power.
  13. A new Section 19 of the code covers photovoltaic generating stations, with sections addressing general codes, location, grounding configurations, vegetation management, DC overcurrent protection, and DC conductors. These new rules accommodate large-scale solar power projects.
  14. In the Clearances section, all rules for wireless antenna structures have been consolidated in the equipment section (Rule 238 and 239), which makes the Code more user-friendly.
  15. A new subcommittee was created focusing on generating stations, with the original subcommittee continuing to address substations.
  16. A working group is investigating Fault Managed Power Systems (FMPS) cables as the technology may be used for 5G networks. The team is looking at possible impacts, including clearances and work rules.

 


February 18, 2021

 

Several proposals recommending improvements to the 2017 National Electrical Safety Code (NESC) were submitted to the IEEE subcommittees drafting the 2022 revision of the NESC.   Some of the proposals deal with coordination with the National Electrical Code — which is now in its 2023 revision cycle.  Keep in mind that that NESC is revised every 5 years at the moment; the NEC is revised every 3 years.

The original University of Michigan standards advocacy enterprise has been active in writing the NESC since the 2012 edition and set up a workspace for use by electrical professionals in the education industry.   We will be using this workspace as the 2022 NESC continues along its developmental path:

IEEE 2022 NESC Workspace

The revision schedule — also revised in response to the circumstances of the pandemic — is linked below::

NESC 2023 Edition Revision Schedule*

 

The NESC is a standing item on the 4-times monthly teleconferences of the IEEE Education & Healthcare Facilities committee.  The next online meeting is shown on the top menu of the IEEE E&H website:

IEEE E&H Committee

We have a copy of the first draft of the 2023 NESC and welcome anyone to join us for an online examination during any of Power & ICT teleconferences.  See our CALENDAR for the next online meeting.

Business unit leaders, facility managers and electrical engineers working in the education facilities industry may be interested in the campus power system reliability database.   Forced outages on large research campuses, for example, can have enterprise interruption cost of $100,000 to $1,000,000 per minute.    The campus power system forced outage database discriminates between forced outages attributed to public utility interruptions and forced outages attributed to the university-owned power system.   The E&H committee will convey some of the discipline applied by the IEEE 1366 technical committee into its study of campus power systems and, ultimately, setting a benchmark for the standard of care for large university power systems.

 

 

* The IEEE changed the nominal date of the next edition; likely owed to pandemic-related slowdown typical for most standards developing organizations.

Readings / The Administrative State

In power system engineering, availability and reliability are two important concepts, but they refer to different aspects of the system’s performance.

Reliability:

  • Reliability refers to the ability of a power system to perform its intended function without failure for a specified period under given operating conditions. It is essentially a measure of how dependable the system is.
  • Reliability metrics often include indices such as the frequency and duration of outages, failure rates, mean time between failures (MTBF), and similar measures.
  • Reliability analysis focuses on identifying potential failure modes, predicting failure probabilities, and implementing measures to mitigate risks and improve system resilience.Availability:
  • Availability, on the other hand, refers to the proportion of time that a power system is operational and able to deliver power when needed, considering both scheduled and unscheduled downtime.
  • Availability is influenced by factors such as maintenance schedules, repair times, and system design redundancies.
  • Availability is typically expressed as a percentage and can be calculated using the ratio of the uptime to the total time (uptime plus downtime).
  • Availability analysis aims to maximize the operational readiness of the system by minimizing downtime and optimizing maintenance strategies.

Reliability focuses on the likelihood of failure and the ability of the system to sustain operations over time, while availability concerns the actual uptime and downtime of the system, reflecting its readiness to deliver power when required. Both concepts are crucial for assessing and improving the performance of power systems, but they address different aspects of system behavior.

On Monday June 13th, Federal Energy Regulatory Commission commissioners informed the House Committee on Energy and Commerce that the “environmental justice” agenda prohibits reliable dispatchable electric power needed for national power security. One megawatt of natural gas generation does not equal one megawatt of renewable generation. The minority party on the committee — the oldest standing legislative committee in the House of Representatives (established 1795) — appears indifferent to the reliability consequences of its policy.

Joint Federal-State Task Force on Electric Transmission

“Our nation’s continued energy transition requires the efficient development of new transmission infrastructure. Federal and state regulators must address numerous transmission-related issues, including how to plan and pay for new transmission infrastructure and how to navigate shared federal-state regulatory authority and processes. As a result, the time is ripe for greater federal-state coordination and cooperation.”

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.

No mention of any reliability related IEEE reliability standards in the present edition.  Why is this?

Section 2: Definitions of Special Terms | PDF Page 46

In the 2023 Handbook, the term “reliability” shows up 34 times.

Looks like improvement since last edition.  Suggest explicit Informational Note, as in the NEC, using “reliability” and referring to other agencies.  “Abnormal events” could be tighter and refer to other standards for abnormal, steady-state events.   The clarification of purpose is welcomed although a great deal remains uncovered by other best practice literature; though that can be repaired in this edition.

Section 11: Protective arrangements in electric supply stations

Section 12: Installation and maintenance of equipment

 

Part 2. Safety Rules for the Installation and Maintenance of Overhead Electric Supply and Communication Line | Page 72

Section 22. Relations between various classes of lines and equipment | Page 80

222. Joint use of structures | Page 82

Where the practice of joint use is mutually agreed upon by the affected utilities, facilities shall be subject to the appropriate grade of construction specified in Section 24. Joint use of structures should be
considered for circuits along highways, roads, streets, and alleys. The choice between joint use of structures and separate lines shall be determined through cooperative consideration with other joint
users of all the factors involved, including the character of circuits, worker safety, the total number and weight of conductors, tree conditions, number and location of branches and service drops, structure
conflicts, availability of right-of-way, etc.

Reliability considerations for sustaining internet service when power supply is absent. 

Part 3. Safety Rules for the Installation and Maintenance of Underground Electric Supply and Communication Lines | Page 220

311. Installation and maintenance

A. Persons responsible for underground facilities shall be able to indicate the location of their facilities.
B. Reasonable advance notice should be given to owners or operators of other proximate facilities that
may be adversely affected by new construction or changes in existing facilities.
C. For emergency installations, supply and communication cables may be laid directly on grade if the
cables do not unreasonably obstruct pedestrian or vehicular traffic and either:

1. The cables are covered, enclosed, or otherwise protected, or
2. The locations of the cables are conspicuous.
Supply cables operating above 600 V shall meet either Rule 230C or 350B.
NOTE: See Rules 014B2 and 230A2d.

Part 4. Work Rules for the Operation of Electric Supply and Communications Lines and Equipment | PDF Page 289


The word “reliability” appears only three times.  Should it track in the NESC or should it track in individual state requirements.  So neither the NEC nor the NESC couples closely with power and communication reliability; despite the enormity and speed of research.
