Hydrogenated jojoba oil is a processed form of jojoba oil, which itself is derived from the seeds of the jojoba plant (Simmondsia chinensis). Jojoba oil is liquid wax and is known for its moisturizing properties and similarity to human sebum, making it popular in cosmetics and skincare products. The hydrogenation process involves adding hydrogen to the oil, resulting in a more stable and solidified product.
Lignoceric acid, also known as tetracosanoic acid, is a long-chain saturated fatty acid with the chemical formula C24H48O2. It is part of the saturated fatty acid family and can be found naturally in various animal and plant fats. Lignoceric acid is characterized by its long hydrocarbon chain, which consists of 24 carbon atoms and is fully saturated (meaning it has no double bonds in its carbon chain).
Social epistemology is a subfield of epistemology, which is the philosophical study of knowledge, belief, and the nature of justification. While traditional epistemology often focuses on individual beliefs and knowledge claims, social epistemology emphasizes the communal aspects of knowledge generation and dissemination. Key features of social epistemology include: 1. **Emphasis on Social Processes**: It examines how social processes, institutions, and practices influence what is accepted as knowledge.
Wax carving is a sculpting technique that involves creating three-dimensional designs from wax. This method is commonly used in various applications, including jewelry making, model making, and in the preparation of objects for metal casting. In jewelry making, artisans use wax to create detailed patterns and shapes that are later cast in metal using the lost-wax casting process.
Springtime lethargy, often referred to in a more general context as "spring fatigue" or "spring lethargy," is a phenomenon where individuals experience feelings of tiredness, low energy, or lethargy as the seasons change from winter to spring. This may be attributed to several factors: 1. **Changing Light Exposure**: With longer daylight hours, the body adjusts to increased light exposure, which can disrupt sleep patterns and circadian rhythms, leading to fatigue.
The weather in 2006 varied widely around the globe, as it typically does in any given year, influenced by seasonal changes, climate patterns, and regional effects. Here are some key weather-related highlights from 2006: 1. **Hurricanes**: The Atlantic hurricane season produced several notable storms, including Hurricane Ernesto and Hurricane Gordon. While the overall season was less active than previous years, it still caused significant damage in some areas.
The weather of 2008 varied widely around the globe, as it does in any given year. Significant weather events included: 1. **Severe Storms**: Many regions experienced severe storms, including tornadoes in the United States, particularly in the Midwest and South. Notably, a series of tornado outbreaks occurred in April 2008. 2. **Hurricanes**: In the Atlantic, the hurricane season was above average.
"Weather whiplash" refers to rapid and extreme fluctuations in weather conditions over a relatively short period of time. This phenomenon can involve sudden transitions from extreme heat to extreme cold, heavy rainfall to drought, or vice versa. Such drastic changes can have significant impacts on ecosystems, agriculture, water supply, and infrastructure. The term is often discussed in the context of climate change, as increased variability in weather patterns is one of the expected consequences of shifting climate conditions.
The term "storms" refers to meteorological phenomena characterized by strong winds, precipitation, and often extreme weather conditions. Storms can vary in type and intensity and are usually caused by the interaction of different atmospheric conditions. Common types of storms include: 1. **Thunderstorms**: Short-lived weather events that can produce heavy rain, lightning, thunder, and sometimes hail or tornadoes.
"Blackberry winter" refers to a specific meteorological phenomenon that occurs in the southern United States, particularly in the Appalachians. It describes a cold snap that typically happens in late spring, often around the time when blackberries are blooming or in fruit. This cold wave can bring temperatures that drop significantly for a short period, resulting in frost or even freezing temperatures. The term is also steeped in cultural significance in certain regions, often reflecting the local connection to the seasonal rhythm of nature.
The Brown Mountain Lights are a phenomenon observed in the Brown Mountain area of North Carolina, near Morganton. These lights are mysterious glowing orbs that appear in the night sky, often described as white, yellow, or orange in color. They are typically reported to float or dart around in the distance, and their origins remain unexplained. Various theories have been proposed regarding the lights, including atmospheric effects, geological activity, and even supernatural explanations.
Farmers' lore jokes often involve humor related to farming, agriculture, and rural life. These jokes typically play on common experiences, stereotypes, and the unique aspects of farm living. They can be light-hearted and whimsical, often drawing on the relationship between humans and nature, livestock, crops, and the challenges of farming. Here are a few examples of farmer-related jokes: 1. Why did the farmer win an award? Because he was outstanding in his field!
The Hessdalen Lights are a series of unexplained lights that appear in the Hessdalen valley in Norway. They have been observed for several decades, with sightings dating back to the early 1980s. The lights are often described as bright, glowing orbs that can change color and move in unpredictable ways. They typically appear in various forms, including stationary lights, lights that move horizontally or vertically, and lights that seem to pulse or flicker.
Kim Atienza, also known as "Kuya Kim," is a well-known television presenter, actor, and animal enthusiast in the Philippines. He gained prominence as a weatherman and a host of various television shows, most notably for his work with ABS-CBN. Atienza is recognized for his fun and engaging presentation style and his segments that often involve discussing a variety of topics, including weather, science, and animals, usually featuring unique trivia and factual information.
A "White Christmas" refers to a Christmas Day when there is snow on the ground or when snow falls on that day. The definition can vary slightly based on regional traditions, but generally, it indicates that either snow cover exists or fresh snowfall occurs on December 25th. Many people associate a White Christmas with a festive and nostalgic atmosphere, often inspired by cultural depictions in films, music, and literature.
3D nowcasting is a real-time forecasting technique used primarily in meteorology to predict weather conditions over a short time frame — typically from minutes to a few hours ahead. Unlike traditional forecasting that might use 2D models, 3D nowcasting takes into account the three-dimensional structure of the atmosphere, allowing meteorologists to represent and analyze data in three spatial dimensions (longitude, latitude, and altitude).
The National Hurricane Center (NHC) is a branch of the National Oceanic and Atmospheric Administration (NOAA), specifically under the National Weather Service (NWS) in the United States. It is responsible for monitoring, forecasting, and providing information about tropical weather systems, including hurricanes and tropical storms.
The Ocean Prediction Center (OPC) is a branch of the National Oceanic and Atmospheric Administration (NOAA) in the United States, which focuses on providing forecasts and information related to ocean and marine weather. The OPC specializes in monitoring and forecasting marine weather conditions, including ocean currents, wave heights, and potential hazards such as storms and heavy seas that can affect both maritime operations and coastal areas.
PERSIANN, which stands for Precipitation Estimation from Remote Sensing Information using Artificial Neural Networks, is a system developed for estimating precipitation using satellite-based data. It leverages artificial neural networks to analyze and interpret remote sensing data, such as infrared satellite imagery, in order to provide estimates of rainfall and precipitation patterns. PERSIANN is particularly useful for regions where traditional ground-based precipitation measurements are scarce or unavailable.
The Regional Snowfall Index (RSI) is a metric developed by the National Oceanic and Atmospheric Administration (NOAA) to assess and compare the impacts of winter storms across various regions in the United States. The RSI quantifies snowfall amounts relative to the typical snowfall for a specific region, taking into account the population density and the potential impacts on people and infrastructure.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.
