1. 1. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

   University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

   Author : Fritjof Nilsson; Yanjun Peng; [2023]
   Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

   Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

3. 2. Biochar and hemp as peat substitutes in organic growing media : effects on nutrient availability and nutrient uptake

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Malin Nilsson; [2022]
   Keywords : Growing media; substrate; biochar; hemp; peat substitution; nutrient availability; nutrient use efficiency;

   Abstract : This study aimed at evaluating the suitability of biochar and hemp as partial or complete replacement of peat in horticultural growing media, with specific emphasis on the effects on nutrient availability and plant nutrient uptake. The study was motivated by the environmental concerns surrounding the use of peat, along with a desire to explore possible uses for biochar and a crop residue from hemp cultivation. READ MORE

4. 3. Design and Evaluation of a Novel Conveyor Utilizing a Screw Mechanism to Move Objects With Integrated Racks

   University essay from KTH/Mekatronik

   Author : Måns Nilsson; Mathias Nils Edvin Nordqvist; [2021]
   Keywords : Screw Conveyor; Intralogistics; Material Handling; Thread Meshing; Worm rack drive; Brushless motor; Skruvtransportör; Intralogistik; Materialhantering; gängingrepp; Snäckskruv och kuggstång; borstlös motor;

   Abstract : Intralogistics, or material handling, traditionally use roller or chain conveyors to moveo bjects and goods in factories and warehouses. One negative aspect of the traditional types of conveyors is that they are expensive, as they are comprised of many moving parts. READ MORE

5. 4. The Impact of Insulation Materials on a Climate Declaration : A Study of a Swedish Preschool

   University essay from Linköpings universitet/Industriell miljöteknik

   Author : Isabelle Hallkvist; Elin Nilsson; [2021]
   Keywords : Climate declaration; Insulation materials; Insulation material; Climate impact; Greenhouse gas emissions; Building and construction sector; Boverket; Glass wool; Stone wool; EPS; XPS; Cellulose fibre; Foam glass; Klimatdeklaration; Isoleringsmaterial; Klimatpåverkan; Växthusgasutsläpp; Bygg- och fastighetssektorn; Boverket; Glasull; Stenull; EPS; XPS; Cellulosafiber; Skumglas;

   Abstract : To reach the net-zero carbon goal by 2045, the Swedish government want to push the building and construction sector to lower their greenhouse gas emissions. This push is performed by implementing a law requiring building developers to perform a climate declaration over greenhouse gas emissions, to receive a building’s final clearance. READ MORE

6. 5. Future diagnostics of sepsis : Defining optimization methods in detection and quantification of circulating microRNA using the QIAcube and two-tailed RT-qPCR

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Andreas Nilsson; [2021]
   Keywords : ;

   Abstract : Sepsis, defined as a life-threatening organ dysfunction, is a condition triggered by an adverse immune reaction often leading to a considerable cost in human lives. A fast and early detection is the cornerstone for treating sepsis, however, current therapeutic standard relies on blood culturing, a slow and non-specific indicator. READ MORE
