11. Effects of plant-fungal interactions on volatile emission of Hordeum vulgare and aphid preference
Master-uppsats, SLU/Dept. of EcologySammanfattning : Barley is one of the most economically important cultivated crops in the world. However, barley is a host for many insect pests and plant pathogenic fungi which is a threat to the production. Rhopalosiphum padi is an economically important insect pest that leads to large economical losses in agricultural crops such as barley. LÄS MER
12. Analysis of Benzoisothiazolinone in process water from operations that handle large amounts of paint residues
Master-uppsats, KTH/KemiSammanfattning : I denna studie undersöks isotiazolinoner i avloppsvatten eftersom det finns i alla kommersiella färger. För att avgöra om reningsverken är tillräcklig bra används gaskromatografi-masspektrometri (GC-MS) för att analysera förekomsten av BIT i processvatten som släpps ut i mjövattnet. LÄS MER
13. Experimental Study of Internal Injector Deposits In Internal Combustion Engines Using Renewable Fuels
Master-uppsats, KTH/MaterialvetenskapSammanfattning : The strive to minimize emissions in the automotive industry keeps gaining momentum. Continuous improvement of engine designs and development of more efficient fuel systems in diesel vehicles is a solution to be applauded. LÄS MER
14. Analyzing components of barrier coatings in different fractions during a repulping process.
Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : During paper manufacturing, coating and adhesives are added to paper and cardboard to improve quality and durability. When the paper is later recycled or becoming new paper, the coatings may pollute the water used in the recycling process. Thus, it is important to know in which fraction these coatings finish during the process. LÄS MER
15. Biomimetically improved materials comprising microfibrillated cellulose
Master-uppsats, Umeå universitet/Kemiska institutionenSammanfattning : Microfibrillated cellulose (MFC) is a renewable, cellulosic material mainly producedfrom wood fibers, which are found in the secondary cell walls of plant cells. With theincreased demand for renewable biopolymer films in packaging, MFC has emerged asa potential alternative to non-renewable polymer films. LÄS MER
