  1. 26. C/O+ charge transfer & the Olson-Demkov model

    University essay from Uppsala universitet/Teoretisk astrofysik

    Author : Kristoffer Bengtsson; [2021]
    Keywords : Astronomy; Charge transfer; rate coefficient; Carbon; Oxygen; energy defect; spectral modelling; supernovae;

    Abstract : Charge transfer reactions and their rates play a key role in correctly estimating element abundances in astrophysical objects such as supernovae. The reaction $C + O^+ \rightarrow C^+ + O(^1D) + \Delta E$ has been shown to be of significance when estimating oxygen abundances through model spectrum evaluations, and the relative rate of this reaction can under certain circumstances completely dictate the neutralization rate of oxygen ions.

  3. 27. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Arnold Mate Kalimukwa; Abuzack Juma Mohamed; [2021]
    Keywords : HEC-RAS; BSTEM; cross section; erosion; sediment transport; deposition; bank stability; safety factor; Technology and Engineering;

    Abstract : This master thesis report presents the results of evaluation of bank erosion and stability analysis along Rönne å (river) at Ängelholm, located in south-west of Sweden within Scania. The main objectives cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to earlier observational study conducted by Norconsult in 2013, and finally conducting analysis of bank stability in most erosive stretches.

    Author : Hector Älfvåg; [2021]
    Keywords : ;

    Abstract : The use of natural gas with high methane content as rocket fuel has gained substantial industrial attention over the past number of years. Several actors including SpaceX and Blue Origin are developing natural gas powered rocket engines. READ MORE

  5. 29. Transverse force absorption in column base mounts for steel columns : Screw joints in column bases

    University essay from KTH/Byggteknik och design

    Author : Dejan Jovanovic; Ruslan Khalilov; [2021]
    Keywords : column bases; transverse force absorption; tightening moment; clamping force; non-prestressed joints; Pelarfötter; tvärkraftskapacitet; åtdragningsmoment; spännkraft; icke förspända förband;

    Abstract : It is common to use different construction materials in combination such as concrete, steel, wood and glass in order to optimize buildings. The purpose of this is to reduce weight and increase load capacity, but it also facilitates assembly and reduces construction time. READ MORE

  6. 30. Impact of Climate Change on Equity Markets

    University essay from Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Author : Ensari Eroglu; Anuj Agrawal; [2021]
    Keywords : climate change; climate vulnerability; climate readiness; fixed effects; ND-GAIN;

    Abstract : Climate change and its effects on our daily life are one of the most visited research topics in the last few years. A growing number of this literature focuses on the impact of climate change on the economy and financial markets, and the threat it may pose on long-term investments. READ MORE
