6. Decay Chains of Fast Alpha Emitters in the Actinide Region
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikAbstract : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. READ MORE

7. Gravitational Collapse of a Massless Scalar Field in a Theory of Minimally Modified Gravity
University essay from KTH/FysikAbstract : This thesis explores the spherically symmetric gravitational collapse of a massless scalar field in a minimally modified gravity theory denoted VCDM (V replaces $\Lambda$ in the $\Lambda$CDM abbreviation), a class of theories propagating the same degrees of freedom as general relativity at the expense of broken 4D diffeomorphism invariance. Numerical evolution of the equations of motion reveals that for small initial scalar profile amplitudes, no black hole forms from the collapse. READ MORE

8. The Abel-Ruffini Theorem : The insolvability of the general quintic equation by radicals
University essay from Umeå universitet/Institutionen för matematik och matematisk statistikAbstract : This thesis explores the topic of Galois theory at a relatively introductory level with the goal of proving the Abel Ruffini theorem. In the first part algebraic structures are considered: groups, ring, fields, etc. Following this, polynomial rings are introduced and the attention is then turned to finite field-extensions.

9. Agonistic Peacebuilding Practices, in Practice? A Study of INGOs Programmatic and Advocacy Work With and For Yazidi Survivors in Northern Iraq
University essay from Lunds universitet/Statsvetenskapliga institutionenAbstract : After the 2014 invasion of contested areas in Iraq by the so-called Islamic State (IS), the Yazidi community has suffered dire consequences. Genocide, sexual enslavement, forced religious conversion and forced displacement were some of these horrendous acts committed by IS against the Yazidi community and other minorities in Iraq and Syria.

10. Diving Deep: Seabird foraging tactics and local prey field
University essay from SLU/Dept. Of Aquatic ResourcesAbstract : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. READ MORE
