Abstract: The present disclosure provides methods, a web server and a user device for generating, transmitting and using customized survey questionnaires. The methods, web server and user device collect behavioral data of a survey participant through a user device, behavioral data indicative of events occurring during a browsing session with respect to an origin. The method and web server generate a customized survey questionnaire based on the received behavioral data throughout the browsing session with respect to the origin, the customized survey questionnaire comprising one of: a survey question selected among a plurality of survey questions from a survey question database based on the received behavioral data, and a survey question generated based on the received behavioral data.

Abstract: The present disclosure relates to a method and a user device for generating and providing customized survey questionnaires. The method and user device monitor events occurring on the user device and generate behavioral data accordingly. Upon detection of fulfillment of a survey trigger condition, the method and user device generate a customized survey questionnaire including a question either selected or generated based on the generated behavioral data. The customized survey questionnaire is generated using survey customization data. The method and user device provide to a user the customized survey questionnaire, collect a response to the question from the user thereby generating survey participation data, and transmit the survey participation data to a survey server.

Abstract: Preservatives and oil are extracted from treated wood. For this purpose, treated wood that is intended to be discarded is comminuted, the chips are impregnated with an alkaline solution until softening of the chips and modification of the chemical state of the products to be extracted. Possibly, the chips may be treated with saturated steam at a temperature between 170.degree. C. and 210.degree. C. followed by an explosive decompression giving wood fragments. This is followed by a refining operation in a crusher permitting the grinding of the wood. The result is a substantial release of the preservatives and oil from the wood chips which are at least partly disintegrated. The chemical preservatives and the oil are collected separately from the wood chips in the aqueous phases which are produced in the impregnation, steam cooking-explosive decompression and refining steps.
