Norfolk Rhapsody is inspired by English folk tunes, particularly from the Norfolk region, which Vaughan Williams collected himself. The piece is lyrical and evocative, capturing the pastoral beauty and maritime heritage of East Anglia. It features rich, sweeping string melodies and gentle woodwind passages, creating a reflective and nostalgic atmosphere. The work, originally conceived as a trilogy, survives only in its first rhapsody. Its folk-inspired themes and lush orchestration showcase Vaughan Williams’ ability to transform traditional melodies into expressive, symphonic music.
Teachers shape lives in ways they may never fully see. A kind word, an extra effort, or a belief in a student’s potential can change the course of a life. Let’s take a moment today to appreciate the educators who have made an impact. 🍎✨ #ThankATeacher#EducationForAll… pic.twitter.com/L74rAXijZC
Today at 11 AM/ET (15:00 UTC) we review the literature that sets the standard of care for prevention, response and resilience of the education facility industry to storms, floods, hurricanes, earthquakes and all other disasters. We will examine a selection of court filings that should inform how facility managers should prepare and respond to disasters, but also identify gaps in best practice literature and (possibly) key in proposals for how those gaps may be removed.

With emphasis on OB-GYN because educational settlements are where families begin and grow among the young.
Many research universities have large medical research and clinical delivery enterprises that provide significant revenue. We periodically scan public consultations for literature that sets the standard of care for the facilities and technologies in these enterprises in education communities.
You are welcomed to join our review of backup power systems (customer-level). Although the term “backup” is not used in the codes and standards that govern electrical power safety and reliability, “backup” is a term of art widely used in design and field practice.

Happy May 17! Constitution Day in Norway, this is how we celebrate. Kids parade by our house. Have a great day, all good people! pic.twitter.com/BKO3fIO6Wo
The genius of bricklayers on view here. A wonderfully ornamental effect is achieved almost entirely through ingeniously combining 228*108*54mm cuboids of baked mud. No sculpted mouldings, no fine imported materials, just brilliant and thoughtful craftmanship. pic.twitter.com/KxZw2HmFLD
When people ask: how difficult was your path? Remember, Just 22 years ago, I came to America I didn’t know a word of English First generation Figuring out everything alone Now to get both MD & PhD The highest degrees Then go for neurosurgery I am blessed 🙏🏾#MedTwitter#MDPhDpic.twitter.com/NsKoIgt1ZO

Beginning at 4 p.m. today, ROTC cadets will keep vigil for 24 hours at the Clarke Memorial Fountain in honor of Veterans Day.
Following the vigil will be a presentation by retired U.S. Air Force Col. Peter Geurtz, a 1975 @NDAlumni and Air Force ROTC Detachment 225 graduate. pic.twitter.com/tl2Oh5ySfR

Yes, there are technical standards and guidelines for district energy systems, though they can vary depending on the region, country, or specific application. District energy systems (DES), which provide heating, cooling, and sometimes electricity to multiple buildings from a centralized source, often rely on a combination of international standards, national regulations, and industry best practices to ensure efficiency, safety, and interoperability.
Some key examples of relevant standards and frameworks include:
ISO Standards:
ISO 50001: This is an international standard for energy management systems, which can apply to district energy systems to optimize energy performance and efficiency.
ISO 52000: Focuses on energy performance of buildings, which can tie into district energy systems when assessing overall efficiency and integration with building infrastructure.
ASHRAE Guidelines (American Society of Heating, Refrigerating and Air-Conditioning Engineers):
ASHRAE publishes guidelines like the District Heating and Cooling Design Guide, which provides technical recommendations for designing, operating, and maintaining district energy systems. It covers piping, heat exchangers, and system integration.
European Standards:
In Europe, the CEN/CENELEC standards (e.g., EN 15316 series) address energy performance in buildings and can include aspects of district heating and cooling systems.
The EU Ecodesign Directive and Energy Efficiency Directive also influence technical requirements for district energy, particularly in terms of efficiency and emissions.
National Codes and Standards:
In the U.S., standards from organizations like the International District Energy Association (IDEA) provide best practices, while local building codes (e.g., based on the International Mechanical Code) may dictate specific requirements.
In countries like Denmark or Sweden, where district heating is widespread, national standards (e.g., from the Danish Standards Foundation) often set detailed technical specifications for piping, insulation, and system performance.
Piping and Materials:
Standards like ASME B31.1 (Power Piping) or EN 253 (for pre-insulated pipes) are commonly used to ensure the safety and durability of piping networks in district energy systems.
While there isn’t a single, universal “District Energy System Standard” that covers every aspect globally, these systems are typically designed and operated based on a combination of the above standards tailored to local needs, climate, and infrastructure. If you’re looking for a specific region or component (e.g., piping, heat pumps, or controls), I can dig deeper into that for you! Let me know.
