2024-04: got two backpacks "for free" with the Lenovo reward points from buying the Lenovo ThinkPad P14s gen4 amd, not bad, that was already cheap and now I got some extra swag:The sport backpack has a fatal flaw: no strap to hold laptop in place, wo it just tumbles back and forth as you walk.

Neither of them have very good padding below the laptop, but at least the Elite one has a slightly elevated inner bag which woudl likely help a lot in case of a drop.

A dioptra is an ancient surveying instrument used for measuring angles in horizontal and vertical planes. It dates back to ancient Greece and was employed by architects, engineers, and astronomers to aid in the construction of buildings, the mapping of land, and the observation of celestial bodies. The instrument typically consists of a straightedge or a graduated arc mounted on a stand, allowing for precise angle measurement.

Georg Friedrich Brander (often mentioned as Georg Friedrich Brander von Stennberg) was a notable figure in the context of 18th-century German literature and philosophy, though he is not as widely recognized as some of his contemporaries. He lived during a time when Enlightenment ideas were prominent in Europe, which influenced various fields including literature, science, and politics.

A laser line level is a type of leveling tool that projects a straight line of laser light onto a surface, allowing for precise alignment and leveling of various construction and installation tasks. It is commonly used in construction, carpentry, and interior design for both horizontal and vertical alignment.

A military sketching board, also known as a sketching or drawing board, is a portable surface used by military personnel, especially in field operations, to create maps, diagrams, and other visual representations. These boards are typically designed to be lightweight and durable for easy transport and use in various environments. Key features often include: 1. **Flexibility:** They can accommodate different types of media, such as pencils, markers, or even digital devices depending on the design.

In surveying, a "pole" is an older unit of measure that is equivalent to 16.5 feet, or 5.5 yards. It is also referred to as a "rod" or "perch." This unit was historically used in land surveying and can be encountered in real estate, agricultural measurement, and mapping. The pole is part of a chain measurement system, where a chain equals 66 feet, and there are 4 poles in one chain.

A surveyor's wheel, also known as a measuring wheel or survey wheel, is a tool used by surveyors, landscapers, and construction professionals to measure distances over land. It consists of a large wheel mounted on a handle, which can be pushed or pulled along the ground. As the wheel rolls, it counts the number of rotations, which can be converted into a measurement of distance.

Livermorium is a synthetic element with the symbol Lv and atomic number 116. It is part of the octupole and is classified as a transactinide element in the periodic table. Livermorium was first synthesized in 2000 at the Joint Institute for Nuclear Research (JINR) in Dubna, Russia, in collaboration with a team from Lawrence Livermore National Laboratory in the United States.

"Sustainable transport pioneers" typically refers to individuals, organizations, or initiatives that are at the forefront of developing and promoting transportation systems and practices that are environmentally friendly, socially inclusive, and economically viable. These pioneers advocate for and implement strategies that reduce carbon emissions, minimize ecological impact, and enhance accessibility while ensuring that transportation meets the needs of present and future generations.

Air travel demand reduction refers to strategies and measures aimed at decreasing the overall demand for air travel. This can be motivated by various factors, including environmental concerns, economic considerations, public health issues, or the desire to reduce congestion at airports and airspace. Key aspects of air travel demand reduction may include: 1. **Environmental Initiatives**: Efforts to mitigate the carbon footprint of air travel, such as promoting alternative modes of transportation (e.g.

A tripod in surveying is a three-legged stand that provides a stable base for supporting surveying instruments, such as total stations, levels, or theodolites. The legs of the tripod are adjustable in length, allowing for leveling on uneven ground, and are often equipped with pointed tips or rubber feet for improved stability on various surfaces.

Censoring is a concept in statistics typically associated with survival analysis and reliability engineering. It occurs when the value of a variable is only partially known due to limitations in observation or data collection. This often arises in time-to-event analysis, such as in medical studies where the time until an event (like death, failure, or remission) is of interest, but some individuals do not experience the event during the study period.

Prognostics is the science and practice of predicting the future condition or performance of a system or component based on its current state and historical data. It is often used in various fields, including engineering, healthcare, finance, and more, to foresee potential failures and facilitate timely maintenance or intervention. Key aspects of prognostics include: 1. **Data Collection**: Gathering data from sensors, historical records, and operational logs to analyze the performance and health of the system or component.

Bicycle touring is a form of travel that involves exploring various destinations on a bicycle, often over extended distances and periods. It combines the enjoyment of cycling with the experience of adventure, exploration, and cultural immersion. Bicycle touring can take many forms, including: 1. **Supported Tours**: Riders may join organized tours that provide logistical support, such as overnight accommodations, meals, and a support vehicle.

Sexually Active Life Expectancy (SALE) is a demographic measure that estimates the number of years individuals can expect to remain sexually active during their lifetimes. This measure takes into account various factors, including physical health, social circumstances, and personal preferences, that can influence an individual's sexual activity. SALE studies often aim to provide insights into the sexual health and well-being of different populations, considering factors such as age, gender, health disparities, and social norms.

Mean Time Between Failures (MTBF) is a key metric used to measure the reliability and performance of a system or component. Specifically, it represents the average time elapsed between one failure and the next during the operation of a system.

Hydrogen cars, also known as hydrogen fuel cell vehicles (FCVs), are automobiles that use hydrogen as a fuel source to power an electric motor. Instead of relying on conventional fuels like gasoline or diesel, these vehicles generate electricity through a chemical reaction between hydrogen and oxygen in a fuel cell. ### Key Features of Hydrogen Cars: 1. **Fuel Cell Technology**: At the heart of a hydrogen car is the fuel cell, which converts hydrogen gas from the tank into electricity.

Rainbow Routes Association is a non-profit organization based in Sudbury, Ontario, Canada, focused on promoting active transportation options and enhancing community trails. Their mission typically involves providing opportunities for outdoor recreation and fostering a strong sense of community through sustainable transportation initiatives. The organization often works on initiatives related to cycling, walking, and other forms of non-motorized transportation, advocating for better trail infrastructure, hosting events, and collaborating with local governments and community groups.

A bicycle, commonly referred to as a bike, is a human-powered vehicle that consists of two wheels attached to a frame. Typically, it is propelled by the rider's legs pedaling and is designed primarily for transportation, recreation, and exercise. Bicycles come in various types, including: 1. **Road bikes**: Lightweight bikes designed for speed on paved roads. 2. **Mountain bikes**: Sturdier bikes designed for off-road cycling on rough terrains.
