1. 21. The Effect of Calcium on Delignification in Kraft Cooking of Eucalyptus

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Eashwara Raju Senthilkumar; [2019]
   Keywords : Delignification; Carbohydrates; Lignin; Yield; Calcium; Delignifiering; Kolhydrater; Lignin; Utbyte; Kalcium;

   Abstract : Delignifiering under sulfat koket innefattar både kemisk nedbrytning och fysisk upplösning av lignin, för vilket närvaron av oorganiska salter, oorganiska anjoner samt oorganiska katjoner (sammantaget benämnda som "Non-process elements", NPEs på engelska) kan ha inverkan på delignifieringens hastighet. Tidigare studier har funnit att ved med högt kalciuminnehåll är svårdelignifierad och att kalcium har potentiell inverkan på ligninlöslighet och kappatal. READ MORE

3. 22. Spectroscopic evaluation of stability and homogeneity of formulated lubricant

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Amir Vranjkovina; [2019]
   Keywords : Lubricants; Base oil; ICP-AES; FTIR; Method validation; Smörjmedel; Basoljor; ICP-AES; FTIR; Metodvalidering;

   Abstract : Lubricant is a common name for a large group of products that are essential for almost every engine or other machinery equipment that include mechanical part movements. Their main application is reduction of the friction between two rubbing surfaces by interposing a lubricating film between them. READ MORE

4. 23. Concussions in Ice Hockey : Accident Reconstructions Using Finite Element Simulations

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Ekant Mishra; [2019]
   Keywords : Concussion; Ice hockey helmet; Accident reconstruction; FE; HBMs;

   Abstract : Ice hockey, one of the most popular sports in the world, is a contact sport that is always associated with huge risks of traumatic brain injuries (TBIs) resulting from high-velocity impacts. Although technology in player protection equipment has advanced over the years, mild traumatic brain injuries (mTBIs) like concussion remain prevalent. READ MORE

5. 24. A Study of Various Parameters Affecting Adhesion of Coatings to Metal Substrates

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Worabhorn Pathanatecha; [2019]
   Keywords : adhesion; coatings; metal substrates; silanes; polyurethanes; surface energy; crosslinking agent; adhesion promoters; vidhäftning; beläggningar; metallunderlag; silaner; polyuretaner; ytenergi; tvärbindningsmedel; vidhäftningspromotor;

   Abstract : The adhesion of coatings is of high importance in the coating industry and a more thorough understanding of adhesion behavior is required. In this thesis work, seven parameters affecting adhesion of silane-modified poly(urethane urea) (PUSi) coatings on pretreated steel and aluminum substrates were studied. READ MORE

6. 25. Effects of Different Load Magnitudes on Longitudinal Growth of Immature Bones

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Emma Dahlgren; [2018]
   Keywords : growth plate; immature bone; metatarsal; longitudinal growth; load magnitude;

   Abstract : In vivo studies of mechanical loading on bone have suggested that load magnitude is one of the parameters that play a vital role in bone adaptation. This study examined how longitudinal growth of immature rat metatarsals is affected by different load magnitudes. READ MORE
