A Soxhlet extractor is a piece of laboratory apparatus [1] invented in 1879 by Franz von Soxhlet. [2] It was originally designed for the extraction of a lipid from a solid material. Typically, Soxhlet extraction is used when the desired compound has a limited solubility in a solvent, and the impurity is insoluble in that solvent. It allows for ...
In embedded systems, a board support package (BSP) is the layer of software containing hardware-specific boot firmware, runtime firmware and device drivers and other routines that allow a given embedded operating system, for example a real-time operating system (RTOS), to function in a given hardware environment (a motherboard), integrated with the embedded operating system.
Tetrachloro-m-xylene (tetrachlorometaxylene, or TCMX) is the organochlorine compound with the formula C 6 Cl 4 (CH 3) 2. It is the chlorinated derivative of m-xylene in which the four aromatic hydrogen atoms are replaced by chlorine. It is prepared by ferric chloride-catalyzed reaction of the xylene with chlorine. [1]
Similar to Python, there is the possibility of extending MicroPython's functionality with custom libraries which extend the ability of the existing libraries and firmware. [ 20 ] In MicroPython, files ending with .py take preference over other library aliases which allows users to extend the use and implementation of the existing libraries.
US Postal Service employees work inside the Los Angeles Mail Processing & Distribution Center on December 3. The facility is currently processing 1 million packages per day.
Python Imaging Library is a free and open-source additional library for the Python programming language that adds support for opening, manipulating, and saving many different image file formats. It is available for Windows, Mac OS X and Linux. The latest version of PIL is 1.1.7, was released in September 2009 and supports Python 1.5.2–2.7. [3]
Common Firmware Environment (CFE), sometimes pronounced as 'cafe', [1] is a firmware interface and bootloader developed by Broadcom for 32-bit and 64-bit system-on-a-chip systems. It is intended to be a flexible toolkit of CPU initialization and bootstrap code for use on embedded processors (typically running on MIPS32/64 instruction set CPUs ...
