The true number remains contested, but is thought to be more than the official 505. Battle of Kollaa The Battle of Kollaa was fought from December 7, 1939, to March 13, 1940, in Ladoga's Karelia, Finland, as a part of the Soviet-Finnish Winter War. Description and outcome. Despite having far fewer troops than the Soviets, the Finnish forces (12th Division) repelled the Red Army because the Soviets were only prepared to proceed along roads.

19568280	Woodstock and Sycamore Traction Company Woodstock and Sycamore Traction Company The Woodstock and Sycamore Traction Company was a short-lived interurban railroad that operated from 1911 to 1918 between the cities of Sycamore and Marengo, Illinois; it never reached its intended destination of Woodstock. Its headquarters and repair shop were in the city of Genoa, midway on the route. The track was never electrified, due to lack of funds, so gasoline-powered cars were used. Three McKeen cars were purchased, but the large cars proved unsatisfactory; they were replaced by two smaller Fairbanks-Morse cars.

19568281	Design history file Design history file A design history file is a compilation of documentation that describes the design history of a finished medical device. The design history file, or DHF, is part of regulation introduced in 1990 when the U.S. Congress passed the Safe Medical Devices Act, which established new standards for medical devices that can cause or contribute to the death, serious illness, or injury of a patient. Prior to this legislation, U.S. Food and Drug Administration (FDA) auditors were limited to examining the production and quality control records of the device. Requirements. The regulation requires medical device manufacturers of and 	Design history file

These design controls consist of a development and control plan used to manage the development of a new product, and a design history file where these activities are documented. These controls are specifically intended to manage a medical device company's new product development activities. Research and development processes aimed at developing new underlying technologies are not subject to these regulations. The requirements for a DHF are documented in FDA Regulation CFR 21 820. Design controls. Each manufacturer of either a class II or class III medical device (as well as a select 	Design history file

The sub-clause 7.3.10 of ISO 13485:2016 requires a manufacturer of a medical device to maintain (and control) a design and development file" for a medical device to document the design history of a medical device. This file shall also contain records for changes in design and development (per device type or family). It might contain e.g. a design and development plan, or test reports; and is thus comparable to the DHF of the FDA  regulations. Similarly, Annex II §3.1 of the EU medical device regulation asks for "information to allow the design stages applied to the device to be understood" to be part of the Technical documentations.
