One of the essential difficulties encountered while preparing a piece for a pre-professional player is defining the piece's technical challenges and doing exercises or etude studies accordingly. Based on this fact, in my thesis, I described the technical challenges of Edouard Nanny's Dragonetti A Major concerto under the headings and suggested technical studies suitable for these difficulties. The titles represented are string crossing, bow strokes, thumb position and vertical-horizontal approaches, harmonic arpeggios and horizontal playing in harmonics, intonation and shifting, and double stops. In the last step of each heading, I associate these technical studies with an excerpt from a more advanced piece than this concerto in the double bass repertoire. Accordingly, the thesis aims to define a working path for Nanny's Dragonetti A Major Double Bass Concerto and, at the same time, to be a preliminary preparation for the more technically challenging works of the repertoire.

The purpose of this project has been to compose and arrange music to be performed by an ensemble using electronic instruments such as synthesizers and samplers. The goal has been to try to create an electronic music ensemble that utilizes improvisation while staying true to the sound of modern electronic music in terms of rhythm, harmony and melody. I have also been investigating how to incorporate the electric bass in this type of music, that most often uses synth bass. This could be done through the use of various effect pedals. I have also done a comparison on how or if jazz improvisation differs from improvisation in electronic music. The type of electronic music that we aimed for sounded better with the use of a more minimalistic approach to improvisation. / <p>Låtlista:</p><p>1. Låt 1</p><p>2. Jungle Fever</p><p>3.

White Bass Morone chrysops is a native, migratory sportfish that is found throughout the central United States in large rivers and riverine impoundments. White Bass migrate into tributaries and riverine portions of reservoirs to spawn during spring. These spawning migrations concentrate fish and may make them more susceptible to angling pressure. White Bass have been well studied in reservoirs throughout the central United States since the early 2000’s when fisheries management practices shifted from population management to fish assemblage management. However, despite the increase in White Bass research in reservoirs, large river populations remain understudied. My thesis research used otolith microchemistry to assess the role of tributaries in supporting White Bass populations in the Ohio, Wabash, Middle Mississippi, Upper Mississippi and Illinois rivers and to compare population demographics (recruitment, growth, and mortality) among rivers. Water samples were collected from each of the five rivers and their tributaries and analyzed for strontium, barium, and calcium concentrations to calculate molar elemental ratios (Sr:Ca, Ba:Ca) and determine if differences in water Sr:Ca and Ba:Ca observed in prior studies persisted among large rivers and their tributaries. Otoliths from White Bass collected from locations where their movement was constrained (e.g., impoundments where dam passage is not possible) were analyzed to characterize relationships between water chemistry (Sr:Ca and Ba:Ca) and White Bass otolith chemistry. I then applied these regression relationships in conjunction with water chemistry data from each of the five large rivers and tributaries in the study area to estimate ranges of otolith Sr:Ca and Ba:Ca for White Bass in each of the rivers and tributaries. Otolith core Sr:Ca and Ba:Ca from White Bass collected from the Ohio, Wabash, Middle Mississippi, Upper Mississippi, and Illinois rivers were compared with predicted river-specific ranges of otolith Sr:Ca and Ba:Ca to identify natal river for each fish. All fish utilized for microchemistry were aged and used to create an age-at-length key from which vital rate parameters were calculated. Microchemistry results indicated that White Bass origin proportions differed among rivers. In rivers with more prominent differences in water Sr:Ca compared to their tributaries and upstream river segments, natal river assignments were more definitive and indicated that large river White Bass stocks are being strongly supplemented by tributaries and other upriver locations. In areas with small differences in water chemistry among potential natal rivers, origin designations were less definitive due to partially overlapping ranges of Sr:Ca and Ba:Ca among locations. A study using genetics to assess natal river fidelity in spawning White Bass should be conducted to better assess stocks and population structure in the large rivers. White Bass populations were dominated by age 0 fish (young of the year). Vital rate parameters were consistent with those of reservoir populations in the central United States, with riverine White Bass exhibiting fast growth, high mortality, and variable recruitment. My results indicated that a holistic approach to large river management should be considered when managing White Bass. Management regulations should reflect those in well studied reservoir populations based upon my findings, but future projects should expand upon our data and focus on population modeling of White Bass in these systems to better understand fishing and natural mortality, especially in areas of concentrated fish during the spawning season.

This study consisted of several experiments designed to compare the ability of two species of fungi, Saprolegnia ferax and S. parasitica to grow on two species of fish, smallmouth bass (Micropterus dolomieui) and goldfish (Carassius auratus), and to determine the criteria necessary for the development of these infections. The results indicate that water in the fish tanks must be slightly acid (pH 6), warm (22°C), nonmoving, and that the fish must be wounded in order for fungal infection to occur. Cool water (18°C) and moving water, caused by aeration and filtration, are detrimental to fungal colony formation so that no infection occurs. Both S. ferax and S. parasitica infected both species of fish, on an average of three days after innoculation. The S. ferax infected a higher percentage of both fishes than did the S. parasitica. The difference in susceptibility of the two fish species to the fungi was negligible.

Since 1995, California State Fish Hatcheries (Feather River, Nimbus, and Mokelumne) and Coleman National Fish Hatchery have raised approximately 29 million 4 fall run Central Valley Chinook salmon (Oncorhynchus tshawytscha) per season for stock enhancement. From April through June, fish are acclimated in net-pens prior to release at one of three sites: the Carquinez Strait at Conoco Phillips (CP), the mouth of the Napa River at Mare Island (MI), and the San Joaquin River at Jersey Point (JP). Striped Bass, Marone saxatilis, are known to congregate at the release location to feed on the hatchery fish as they enter the Delta and Bay, and are suspected to be reducing numbers of Chinook recruitment. Dual-Frequency Identification Sonar (DIDSON) was used to capture video-like images to enumerate and estimate sizes of potential predators in the area. Stomach analysis was used to obtain consumption rate data and a simple model was used to estimate predator impacts on the hatchery fish. Data was collected in 2011 and 2012. In 2011 the striped bass population at CP was significantly larger than MI (p=0.009) and JP (p=0.038) and in 2011 , and MI (p=0.046) in 2012. Predators were significantly smaller (range 11.8-61.7 em, mean 34.6 em in 2011 ; 21-67 em, 42.9 in 2012) atJP (p<0.001). Average size predator at MI was 47.3 em (range 31-59 em) in 2011 and 50.9 em (range 33-73 em) in 20 12; and at CP was 48.3 em (range 16-77 em) in 2011 and 52.7 em (range 31-78 em) in 2012. On average an estimated 2.2% of hatchery fi sh are consumed each year by striped bass and predator impacts are greatest at CP (p<0.001). Changing the release site often could improve salmon survival by decreasing predator attraction to the site and reducing immediate predator-prey encounters.

This thesis is about register and how it affects my playing through compositions and improvisation. As a brass musician, the high and low range is something that takes a lot of effort to master. How important is register for my artistic expression and how does register influence my music?  My method to test this is by composing with a template where I have three musical components that I arrange in different registers. The first component is melody. The second one is ostinato, which in this thesis means something rhythmical that creates movement through time. The last component is harmony.  In the next part of the thesis, I analyze all of my compositions and describe how I have worked with the template. I have also written about what difficulties we encountered as a band when we rehearsed the music. The band consists of me on trombone and bass trombone, Olle Vikström on tenor and baryton saxophone, Sara Karkkonen on piano, Johan Tengholm on bass and Henrik Jäderberg on drums. In the end of this thesis I discuss how register have influenced how the components work together like the clarity of the melody and how the harmony is affected by the melody.I find the instrumentation is of higher influence than the register but this specific constellation of instruments may have influenced how I perceive the components. / <p>Konserten innehöll Fem originalkompositioner av Simon Skogh</p><p>Det var följande låtar</p><p>Vårflod</p><p>Väg 83</p><p>Stresspåsag</p><p>Reserestriktioner</p><p>Lyckligt slut</p><p></p><p>Medverkande musiker var</p><p>Simon Skogh tenortrombon och bastrombon</p><p>Olle Vikström tenorsaxofon och barytonsaxofon</p><p>Sara Karkkonen piano</p><p>Johan Tengholm Bas</p><p>Henrik Jäderberg Trummor</p><p></p><p>På grund av ett tekniskt fel fungerar inte en video som är inlagd i mitt arbete på sida 5 den är därför en egen fil uppladdad här.</p>

Lake Moomaw, a 1,024-ha flood control reservoir in Bath and Allegheny counties, Virginia contains a migratory population of smallmouth bass that congregate in the headwaters of the reservoir during the spring spawning period, where they are vulnerable to a shore-based, harvest-oriented fishery. The extent of this fishery and resulting effects on the small mouth bass population were analyzed by means of a creel survey in the headwaters area during the spring spawning seasons of 1995 and 1996. Effort, catch, and harvest, as well as user characteristics and motivations data were obtained from direct interviews with anglers using this area. Estimates for 1995 indicated extensive fishing pressure per ha, with 1,167 angler hours per ha spent fishing for smallmouth bass in the headwaters, while in 1996 almost 1,400 angler hours per ha were spent in this area. Catch and harvest rates were relatively low and sustainable during both years, with 124 small mouth bass caught and 82 harvested in 1995, while 318 small mouth bass were caught and 222 harvested in 1996. An extensive capture-recapture study yielded estimates of exploitation rates for small mouth bass in the reservoir of 12- 15% annually. Exploitation of the whole-lake population occurring in the spring headwaters fishery was estimated at 4-6%, while the exploitation rate on the subset of the population using the headwaters during the spring was 11-14%. Analysis of movements of snlallmouth bass in the reservoir using ultrasonic telemetry and dart tag recaptures indicated that the subset of the population using the headwaters was mainly drawn from the upper and middle portions of the reservoir, and that significant amounts of spawning occurred in the lower section of the reservoir as well. Areas used by smallmouth bass for reproduction were documented with summer and fall electrofishing to determine relative abundance of young-of-the-year smallmouth bass in the reservoir, and showed spawning to take place throughout the reservoir. Densities of young-of-the-year shifted as fall progressed, with highest densities in the middle portion of the reservoir in early fall, indicating that reproductive inputs from the headwaters were realized in the lake as fall progressed. The headwaters fishery is a high-profile activity which, during 1995-96, had a low and sustainable impact on the Lake Moomaw smallmouth bass population. / Master of Science

Utah Lake, located in Utah County, north-central Utah, is one of the most important natural fishing lakes in the state. The spawning ecology of the white bass (Roccus chrysops) was studied in Utah Lake between 1964 and 1966. Gill nets and seining were the primary means of sampling. The spawning location was sampled every other day throughout the spring and early summer of 1966. Three major winter schooling areas were found: Provo Bay - Creer Access south to the mouth of Spanish Fork River, Lincoln Beach, and off Ludlow Barn. There appears to be extensive winter feeding and movement among the white bass populations. Immature white bass of both sexes were found in large numbers throughout the entire lake during the summer. In the early spring months, bisexual schools of mature bass concentrated in the southern portions of the lake before forming into unisexual schools in mid-April. Spawning activities were restricted to an area adjacent to Lincoln Beach, 0.25 mile and to a depth of 60 inches. Rubble, interspersed with ledge rock and boulders, were the only bottom types selected for spawning. An area surrounding Bird Island also simulated the bottom types off Lincoln Beach, but was not utilized for spawning. Gravid females were taken in the vicinity of Lincoln Beach on May 6, 1966 when water temperatures had reached 63° F. Spawning activity lasted from 10 to 15 days in mid-June in water temperatures of 69° F. Unisexual schools of gravid females were found off Creer Access a distance of three miles from the spawning grounds. Small numbers of female bass would migrate to the spawning site, spawn, and return to the vicinity of Creer Access, never remaining over the spawning site longer than to spawn. Tributaries were not utilized for spawning, although bass were sampled feeding in the Provo River in mid-August. Turbidity of Utah Lake during the spring and summer prevented any observations of spawning activity or behavior. Summer sampling throughout Utah Lake in 1965 resulted in a 2:1 (174 males - 93 females) sex ratio. However, these figures are in conclusive as they did not include gravid females.
