Line radiative transfer and statistical equilibrium*
Full text linkAtomic and molecular line emission from protoplanetary disks contains key information of their detailed physical and chemical structures. To unravel those structures, we need to understand line radiative transfer in dusty media and the statistical equilibrium, especially of molecules. I describe here the basic principles of statistical equilibrium and illustrate them through the two-level atom. In a second part, the fundamentals of line radiative transfer are introduced along with the various broadening mechanisms. I explain general solution methods with their drawbacks and also specific difficulties encountered in solving the line radiative transfer equation in disks (e.g. velocity gradients). I am closing with a few special cases of line emission from disks: Radiative pumping, masers and resonance scattering
Kamp mot rivningsraseriet
No full textUnder rivningsraseriet på 1960- och 70-talen försvann 40 % av Sveriges äldre bostadsbestånd och i städerna gapade stora hål. Många liknade stadslandskapet vid en krigszon. Det handlade om att ersätta Sveriges gamla städer med moderna städer, och om att bygga bort Lortsverige. Otaliga människor förlorade sina hem och livsmiljöer genom rivning utan att först ha blivit tillfrågade. Och till en början var det tyst, inga protester. För den som var lyhörd fanns det dock gott om kritiska reflektioner och skepsis redan tidigt i processen: den uttrycktes av stadsforskare, arkitekter och deras studenter. Var de befintliga stadsmiljöerna verkligen så dåliga och utan värden? Varför kunde husen inte renoveras? Handlar detta inte om vår kulturhistoria? Fanns det inga andra sätt att planera dessa områden

No full textABSTRACT Vilnius University Faculty of Medicine Department of Rehabilitation, Physical and Sports Medicine Bachelor Degree of Physiotherapy PSYCHOEMOTIONAL STATE RELATIONSHIP WITH HEAD AND NECK MUSCULOSCELETAL SYSTEM FUNCTIONS IN 6-13 YEAR AGE CHILDREN WITH BRUXISM Physiotherapy Bachelor's Thesis The Author: Inga Skirmantiene Academic advisor: PhD, lect. Inga Muntianaite Key words: bruxism, psychological problems, head position (craniovertebral angle), mandibular range of motion, deep neck flexor endurance. The aim of research work: To determine the relations of psychoemotional condition of the 6 to 13 year old children who have bruxism with their head position, mandibular range of motion and the deep neck fexor endurance. Tasks of work: 1. To determine the psychoemotional condition of the 6-13 year old children with bruxism by using the Strengths and Difficulties Questionnaire. 2. To determine and compare with normative data scores the head position, mandibular range of motion and the deep neck fexor endurance of the 6 to 13 year old children with bruxism. 3. To determine the correlative relations of the 6 to 13 year old children who have bruxism with their head position, mandibular range of motion and the deep neck fexor endurance. Materials and methods: there were 27 children with bruxism participating in the research, 16 boys and 11 girls, whose ages were 6 to 13 years old. The age of the children has been chosen in accordance with the mixed type teeth condition, the children of such age have either permanent or temporary teeth. The research has been conducted in dental clinic “Skraidenta” from 07/11/2016 to 10/04/2017. There has been a Strengths and Difficulties Questionnaire (SDQ) used in the research, as well as the application of photographic measurements of head posture, measurements of mandibular range of motion and the test of the deep neck flexor. The data analysis has been carried out by using the analytic SPSS Wind. 17.0 and Excel 2007 progr. Results: upon the evaluation of the psychoemotional problems of the 6 to 13 year old children with bruxism by the Strengths and Difficulties Questionnaire, it has been determined the average or large deviation from the norms in all scales of the questionnaire. Especially large, even 66,67 percent, deviation has been determined in the scale of “emotional problems”. Positive correlation between age and scales of “emotional” and “peer relationship” problems of Strengths and Difficulties Questionnaire was found: upon the increase of the age, there is an increasing number of emotional problems and problems with the peers (p<0,05). The head position and mandibular range of motion among the children with bruxism statistically significantly has not differed from the norms. The deep neck flexor endurance has been determined on average by 15,07s, this is almost less by half than the norm (p<0,05). There has been a negative correlation detected between the scale of the “emotional problems” of the SDQ and the head position: upon the increase of the emotional problems, the angle of the head position kept decreasing. The positive correlative relation (p<0,05) between psycholemotional problems and deep neck flexor endurance of the 6 to 13 year old children with bruxism, has been detected only in the scale of “hyperactivity” of the Strengths and Difficulties Questionnaire: upon the increase of the “hyperactivity”, there also increases the deep neck flexor endurance. Conclusions: 44,43 percent of 6 to 13 year old children with bruxism, experience psychoemotional problems. Deep neck flexor endurance between the 6 to 13 year old children with bruxism was lower by half than the norm. There have been negative correlation found between the scale of “emotional problems” of the SDQ and the head position and positive correlation between the scale of “hyperactivity” and the deep neck flexor endurance

No full textIn this conference paper (draft or handout) the author discusses a number of sound changes in Akha, for instance merging sounds in the younger generation, and merging of the alveolar affricates and fricatives with palatals. The author illustrates how the latter merge occurs with open syllables, laryngealized syllables, including cases where loss of palatalization is found. These changes are also compared with the closely related languages Hani, Khatu, and Pijɔ. The author also discusses possible future changes that come from proto-languages which have developed as types of tendencies in some languages. The handout contains five appendices with langauge inventories and a great variety of examples. This handout was first presented at the 7th Himalayan Languages Symposium in 2001 incl. app. 1-5. A similar version without the appendices was presented at the 5th International Conference on Hani/Akha Culture in 2005

No full textThis is an incomplete handout about reduplication in Akha. The author illustrates cases in which reduplicaiton shows a simultaneous action, in combination with serial verb constructions, repeated nouns with two unprefixed adjectives, and reduplication with classifiers and tone change. 29 sentences of Akha, word-to-word-glossing, and free translation to English are provided by the author to illustrate reduplication. This handout was prepared for the 30th ICSTLL, Beijing, 1997

The amount of the bachelor’s work: •page count 46 •number of tables 2 •number of pictures 8 •number of attachments 1 The theoretical part is based on the Latvian author: I. Stangaines, I. Lieginieces S. Laizans, as well as other authors, on the importance of communication in human life, the role of movement in the development and development of the child. The work analyses the author's findings on the development of a child, legal relationships, as well as the learning of the types of play and the importance of the playing of movements in the development of communication skills. The empirical section observed and compared child-to-child exposure skills in mid-childhood children through motion play. In the practical part, the author uses different methods: observation, negotiation with children, anketting and analysis. The work includes a variety of learning from a psychologist and an educator about communication and its importance as an integral part of life, so that a person develops and develops himself, both physically and mentally, as well as learning about movement games, its ways and its role in the development of communication skills. At the very end of the study, it can be concluded that communication skills are developing and improving in the game of movement. The key words: INTERFACE, SKILL, PLAY, PRESCHOOL.
