1. 6. Ultrafast Coherent X-ray Diffractive Nanoimaging

   Författare :Filipe R. N. C. Maia; Janos Hajdu; David van der Spoel; Keith Nugent; Uppsala universitet; []
   Nyckelord :XFEL; Phasing; Image Reconstruction; Single Particle Imaging; Ultrafast Diffraction; X-ray diffraction; Coherent Diffractive Imaging; CXDI;

   Sammanfattning : X-ray lasers are creating unprecedented research opportunities in physics,chemistry and biology. The peak brightness of these lasers exceeds presentsynchrotrons by 1010, the coherence degeneracy parameters exceedsynchrotrons by 109, and the time resolution is 105 times better. LÄS MER

4. 8. Self-Knowledge/Self-Regulation/Self-Control: A Ubiquitous Computing Perspective

   Författare :Lars Hall; Kognitionsvetenskap; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pervasive computing; affective computing; persuasive computing; Psychology; Psykologi; ubiquitous computing; computer-mediated extrospection; precommitment; distributed motivation; distributed cognition; neurofeedback; biofeedback; metacognition; brain-imaging; learning strategies; emotion regulation; mental strategies; verbal report; implicit learning; consciousness; introspection; self-control; Self-knowledge; self-regulation;

   Sammanfattning : This thesis is about self-knowledge, self-regulation and self-control. All three of these terms are easily understandable, and apply to situations in our daily lives (like misjudging one’s own competence at retiling the bathroom floor, or feeling the anxiety and thrill of doing unsupervised work, or guiltily hitting the snooze-button for the fifth time, and missing half a day of school).

5. 9. More than just enduring − Mental health and well-being among Swedish young adults who ceased self-injuring since adolescence

   Författare :Benjamin Claréus; Institutionen för psykologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; self-injury; self-harm; cessation; recovery; adolescence; well-being; mental health;

   Sammanfattning : Non-suicidal self-injury (NSSI) is an umbrella term for non-lethal behaviours that are unlikely to be intended as suicidal, such as cutting, hitting, or burning oneself. The aims of this dissertation were to investigate i) the mental health and well-being of Swedish young adults who have ceased engaging in NSSI since adolescence, and ii) the psychosocial conditions that facilitate NSSI cessation and psychological growth during this period.

7. 10. Photon Upconversion in Heavily Doped Semiconductors

   Författare :Kilian Mergenthaler; Fasta tillståndets fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; III-V semiconductor materials; nanowires; photoluminescence; Photon upconversion; semiconductors; doping; Fysicumarkivet A:2016:Mergenthaler;

   Sammanfattning : In this thesis the luminescence properties of highly doped semiconductors are studied with focus on degenerately n-doped InP. It is demonstrated how photoluminescence measurements on degenerately doped semiconductors allow an estimation of the doping concentration without need for electrical contacts. LÄS MER
