Indoor plumbing has a long history, but it became widely available in the 19th and early 20th centuries. In the United States, for example, the first indoor plumbing system was installed in the Governor’s Palace in Williamsburg, Virginia in the early 18th century. However, it was not until the mid-19th century that indoor plumbing became more common in middle-class homes.
One important milestone was the development of cast iron pipes in the 19th century, which made it easier to transport water and waste throughout a building. The introduction of the flush toilet in the mid-19th century also played a significant role in making indoor plumbing more practical and sanitary.
By the early 20th century, indoor plumbing had become a standard feature in most middle-class homes in the United States and other developed countries. However, it was still not widely available in rural areas and poorer urban neighborhoods until much later.
“Europe today has little desire to reproduce itself, fight for itself or even take its own side in a argument. By the end of the lifespans of most people currently alive, Europe will not be Europe and the peoples of Europe will have lost the only place in the world we had to call home”
Large European universities such as Rijksuniversiteit Groningen are integrated into the fabric of the surrounding city. There are several ways in which this integration takes place:
Physical location: Many European universities are located in the heart of the city, often in historic buildings that have been repurposed for educational use. This central location means that the university is easily accessible to students and the general public, and that it is often surrounded by other cultural institutions, such as museums, theaters, and libraries.
Student life: The presence of a large student population can have a significant impact on the city’s culture and economy. Many European cities have developed a vibrant student culture, with cafes, bars, and other venues catering to the needs and interests of young people. This can help to create a sense of community between the university and the city, and can also bring economic benefits to local businesses.
Research and innovation: Large European universities are often at the forefront of research and innovation, and they can be important drivers of economic growth in the surrounding region. Many universities work closely with local businesses and industries, and they may also collaborate with other universities and research institutions in the area.
Cultural exchange: Universities can be important centers of cultural exchange, both for international students and for local residents. Many European universities offer language classes and other cultural programs that are open to the public, and they may also host lectures, concerts, and other events that are designed to promote cross-cultural understanding.
Overall, the integration of large European universities into the city is a complex and multifaceted process that can have a significant impact on the social, cultural, and economic life of the surrounding region.
The origin of brown cafés can be traced back to the 17th century, during the Dutch Golden Age. At that time, the Netherlands was a prosperous and influential trading nation, and Amsterdam was a bustling city with a thriving port. Sailors, merchants, and locals needed places to socialize, relax, and conduct business, leading to the emergence of taverns and pubs.
The term “brown café” is believed to have originated from the brownish stains that formed on the walls and ceilings due to tobacco smoke, candle soot, and other atmospheric elements. These stains gave the cafés a distinct, cozy ambiance and a sense of history.
Brown cafés became an integral part of Dutch culture, serving as communal gathering spots for people of all walks of life. They were places where locals would meet friends, engage in conversations, enjoy a drink, and sometimes play board games like chess or backgammon. Over time, brown cafés became associated with an authentic, unpretentious, and relaxed atmosphere, attracting both locals and tourists.
The unique charm of brown cafés lies in their preserved historical interiors, with old wooden furniture, dim lighting, and a wide selection of local beers and spirits. Many brown cafés still retain their original character, transporting visitors back in time and providing a cozy retreat from the hustle and bustle of modern life.
While the concept of brown cafés originated in the Netherlands, similar types of establishments can also be found in other European countries, such as Belgium and parts of Germany. However, the term “brown café” is primarily associated with the Dutch tradition of cozy, atmospheric, and convivial drinking establishments.

“The Tower of Babel” 1563 | Pieter Bruegel the Elder
Widely accepted definitions (sometimes “terms of art”) are critical in building codes because they ensure clarity, consistency, and precision in communication among architects, engineers, contractors, and regulators. Ambiguity or misinterpretation of terms like “load-bearing capacity,” “fire resistance,” “egress” or “grounding and bonding” could lead to design flaws, construction errors, or inadequate safety measures, risking lives and property.
“Standardized” definitions — by nature unstable — create a shared language that transcends local practices or jargon, enabling uniform application and enforcement across jurisdictions. Today at the usual hour we explore the nature and the status of the operational language that supports our raison d’êtreof making educational settlements safer, simpler, lower-cost and longer-lasting.
It is impossible to overestimate the sensitivity of this topic but poke at it, we will. At the moment, the less written here; the better. Much of this domain is outside our wheelhouse; though it has settled on a few first principles regarding patents, trademarks and copyrights relevant to the user-interest we describe in our ABOUT.
Many large research universities have a watchdog guarding its intellectual property and trying to generate income from it, and; of course, for branding. We will dwell on salient characteristics of the intellectual property domain with which we reckon daily — highlighting the market actors and the standards they have agreed upon.
Additionally, technical standards developers are generally protected by copyright law, as the standards they create are typically considered original works of authorship that are subject to copyright protection. In the United States, the Copyright Act of 1976 provides copyright protection for original works of authorship, which includes technical standards. This means that the developers of technical standards have the exclusive right to reproduce, distribute, and create derivative works based on their standards, and others must obtain permission or a license to use or reproduce the standards.
Some technical standards may be subject to certain exemptions or limitations under copyright law. In the United States, there is a doctrine called “fair use” that allows for limited use of copyrighted works for purposes such as criticism, comment, news reporting, teaching, scholarship, or research, without the need for permission or a license from the copyright owner. Almost everything we do at Standards Michigan falls under the fair use doctrine. This is why we have no search feature and most pages are protected. If we err in this; let us know.
Patent Act: This is the primary federal law governing patents in the United States. It sets forth the requirements for obtaining a patent, the rights of patent owners, and the remedies available for infringement.
Title 37 of the Code of Federal Regulations: This contains the rules and procedures related to patents, including rules governing the filing and examination of patent applications.
America Invents Act: This is a major overhaul of the U.S. patent system that was enacted in 2011. It includes provisions such as the transition to a “first-inventor-to-file” system and the creation of new post-grant review procedures for challenging the validity of patents.
Manual of Patent Examining Procedure: This is a guidebook for patent examiners that provides detailed information on the rules and procedures for examining patent applications.
Vad är en standard? Syftet med standarder är att skapa enhetliga och transparenta rutiner som vi kan enas kring. Det ligger ju i allas intresse att höja kvaliteten, undvika missförstånd och slippa uppfinna hjulet på nytt varje gång. https://t.co/zKhgPXPdpWpic.twitter.com/oKejdKSm47

“Ironically, on the 200th anniversary of our Bill of Rights, we find free speech under assault throughout the United States, including on some college campuses. The notion of political correctness has ignited controversy across the land. And although the movement arises from the laudable desire to sweep away the debris of racism and sexism and hatred, it replaces old prejudice with new ones. It declares certain topics off-limits, certain expression off-limits, even certain gestures off-limits.”

The United States Food and Drug Administration and the National Coffee Association recommended standard temperature for safe hot coffee is around 160°F to 165°F (71°C to 74°C). This temperature range is considered hot enough to be enjoyable while minimizing the risk of scalding or burning.
These agencies do not have specific regulations or guidelines solely dedicated to cold brew coffee. However, there are general principles and best practices for handling and storing perishable food products that can be applied to cold brew coffee to ensure safety.*
Cold brew coffee typically requires more time to prepare than traditional hot brew coffee. While hot brew coffee can be made in just a few minutes, cold brew coffee is made by steeping coffee grounds in cold water for an extended period of time, usually between 12 to 24 hours.
The longer steeping time allows the coffee to extract more slowly and results in a smoother, less acidic coffee concentrate. After steeping, the coffee grounds are usually filtered out and the resulting concentrate can be diluted with water, milk, or other liquids and served over ice.
While cold brew coffee does require more time to prepare, many coffee drinkers prefer its smoother, less bitter taste and lower acidity compared to hot brewed coffee. Additionally, the longer shelf life of cold brew coffee concentrate makes it a popular choice for those who like to prepare coffee in advance and have it ready to drink throughout the day.
We cover the technical standards applicable to small to medium sized coffee preparation installations in a cross-cutting way during our Kitchens 200 colloquium.
* These recommendations are based on general food safety practices:
Water quality: Start with clean, potable water to brew your cold brew coffee. Make sure the water source is safe and free from contaminants.
Brewing process: Follow good manufacturing practices and ensure that your brewing equipment and utensils are clean and sanitized. Cold brew coffee is typically brewed using room temperature or cold water over an extended period. Ensure that the brewing container is properly sealed and protected from any potential sources of contamination.
Filtration: After the brewing process, filter the cold brew coffee to remove any sediment or particles. This can be done using a fine-mesh sieve or a dedicated filtration system.
Storage: Store the cold brew coffee in a clean, airtight container in the refrigerator. This helps to inhibit the growth of bacteria and maintain the quality of the coffee. Cold brew coffee can typically be stored for a few days to a couple of weeks, depending on the specific recipe and preparation method.
Temperature control: Keep the cold brew coffee refrigerated at a temperature below 41°F (5°C) to prevent the growth of harmful bacteria.
Serve safely: When serving cold brew coffee, use clean and sanitized utensils, containers, and dispensing equipment to avoid cross-contamination. If you add any additional ingredients like milk or sweeteners, ensure that they are stored properly and do not exceed their recommended storage times.
