  2. 1. Strength Properties of Paper produced from Softwood Kraft Pulp : Pulp Mixture, Reinforcement and Sheet Stratification

    Author : Hanna Karlsson; Luciano Beghello; Lars Nilsson; Lennart Stolpe; Öyvind Gregersen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper strength; tensile strength; tearing resistance; folding endurance; fracture toughness; handsheet former; stratify; multilayer; multiply; reinforcement; refining; beating; abaca; glass fibre; polyester; lyocell; softwood; bond strength; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

    Abstract : For paper producers, an understanding of the development of strength properties in the paper is of uttermost importance. Strong papers are important operators both in the traditional paper industry as well as in new fields of application, such as fibre-based packaging, furniture and light-weight building material.

    Author : Villiam Vejbrink Kildal; Andres Rodriguez-Lorenzo; Patrik Lassus; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; facial paralysis; facial palsy; facial synkinesis; synkinesis; facial contracture; facial nerve reconstruction; nerve transfer; nerve graft; microsurgery; myectomy; depressor anguli oris; depressor labii inferioris; platysma; mentalis; lacrimal gland; botulinum toxin; injection; ultrasound; sonography; ultrasonography; crocodile tears syndrome; gustatory hyperlacrimation; excessive tearing; literature review; review; classification system; management algorithm; plastic surgery; static reconstruction; dynamic reconstruction; Plastikkirurgi; Plastic Surgery;

    Abstract : Background: Despite advances in the management of facial paralysis and its associated sequelae, therapies targeting the lower facial region remain underdeveloped. This thesis aimed to improve both the diagnostic and therapeutic modalities for facial paralysis, with a focus on the lower face. READ MORE

  6. 4. Problems in the Aluminium DC Casting Process Associated with Melt Treatment Operations

    Author : Ghadir Razaz; Torbjörn Carlberg; Arne.K Dahle; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The quality of DC cast Al alloys is highly dependent on melt batch composition and impurity level in the molten alloy. The chemical composition and cleanliness of a melt is controlled through the melt treatment operations, carried out while the melt is still in the furnace before casting starts. READ MORE

  7. 5. Modeling of fracture and damage in rubber under dynamic and quasi-static conditions

    Author : Elsiddig Elmukashfi; Martin Kroon; Krishnaswami Ravi-Chandar; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Abstract : Elastomers are important engineering materials that have contributed to the different technical developments and applications since the 19th century. The study of crack growth mechanics for elastomers is of great importance to produce reliable products and therefore costly failures can be prevented. READ MORE
