Para análise de séries temporais também foi proposto um algoritmo de monitoração de dados que permite detectar "outliers" nas séries temporais que podem provocar mudanças na direção de causalidade de variáveis econômicas.

Syftet med den här uppsatsen var att undersöka hur och varför Grava landskommun blev en del av Karlstads kommun och vad som hände med partiorganisationerna efter sammanslagningen 1971. Samt att ta reda på vad som hände de sista åren som egen landskommun. Det gjordes med en kvalitativ texttolkning för att identifiera politikernas och partiorganisationernas ställningstagande och åsikter gällande kommunsammanslagningen. Uppsatsens forskningsfrågor var: • Hur gestaltade sig samarbetet mellan Grava landskommun och Karlstads stad fram till kommunsammanslagningen 1971? • Hur såg diskussionen ut fram till sammanslagningen med Karlstads kommun ut i Grava på det lokalpolitiska planet? Hur ställde sig politikerna i frågan? • Vad hände inom de tre borgerliga partiernas organisationer i Grava efter sammanslagningen? Genom att studera en kombination av arkivmaterial från partiorganisationer och kommunala organ kan man se att Grava landskommun inte hade mycket till val än att bli en del av Karlstads kommun, både från ett juridiskt håll och hur orterna allt mer växte samman.Sammanslagningen firades av kommunledamöterna och det sågs som nästa oundvikliga steg i Gravas utveckling och att man försökte i Folkpartiet och Centerpartiets fall fortsätta representera Gravas intressen i Karlstads kommun.

To better understand the nature of maize dwarf mosaic virus (MDMV) and its interaction with susceptible and resistant corn hybrids, the purification of MDMV and its physical properties were re-evaluated and a rapid assay procedure was developed. The virus was purified by chloroform clarification and differential and sucrose density-gradient centrifugation. Corn tissue was homogenized in 0.1 M sodium citrate plus 0.5% mercaptoethanol. The virus was resuspended after high speed centrifugation in 0.005 M sodium citrate, pH 7.0. Purified virus has an ultraviolet absorption spectrum typical for filamentous viruses having 5% RNA, shows birefringence, has an A260/280 of 1.18, and a sedimentation coefficient of 160-162 S. The virus is filamentous and appears to be a member of the potato virus Y group. A yield of 9.0-23.0 llg of virus/g fresh weigh.t of field-grown, mechanically inoculated Hy X Cl03 was determined by analytical sucrose density-gradient centrifugation. This represents a yield of purified virus of approximately 25% of that in the clarified sap. Results obtained from the density-gradient analysis were comparable to but more sensitive than those from the microprecipitin test and a systemic infectivity assay. The systemic infectivity assay on corn, analyzed by maximum likelihood and log log transformation, showed a yield of purified virus of 0.4% of that in the crude sap. / Ph. D.

A gas chromatograph, equipped with a flame ionization detector, was used to qualitatively and quantitatively analyze the monoterpenes of Virginia pine. The instrument was adjusted for optimum performance prior to sample analysis. Two packed columns with stationary phases of different polarity, Carbowax 20M and polyphenyl ether + Igepal + Versamid-9JO, were used predominantly for analytical determinations. However, a S.C.O.T. column coated with UCON LB550X stationary phase, was used for measuring some compounds. The monoterpenes of Virginia pines were analyzed from foliage, phloem, and bark distillates, pentane extracts of xylem resin and beetle pitch tubes, and foliage and tree-bole vapors. Qualitative determinations were made by comparing relative retention time with known chemicals and mixtures of chemicals, and by introducing these standards into the sample. Quantitative determinations were based on normalization of peak areas for the known components. Peak areas measured with a disc integrator for liquid samples, and with a planimeter for vapor samples. / Ph. D.

A comprehensive. qualitative and quantitative survey of parasites of 176 gray squirrels. Sciurus carolinensis pennsylvanicus, Ord. 1815, was conducted from September, 1966, to July, 1969, in southwestern Virginia. Most of the hosts came from Montgomery County, some being taken also from Giles and Craig counties. Of that total, 167 were examined for coccidia and intestinal flagellates; 84 were examined for blood parasites; 175 were examined for helminths and 106 for ectoparasitlc arthropods. The incidence of coccidiosis was 91% in which five species were described and identified with the genus, Eimerla. The sporozoan, Hepatozoon griseiscuri Clark. 1958, occurred In the blood as evidenced by a 58% incidence in stained blood smears and 79% in blood concentrates. Excysted gametes of this species were kept in vitro for four days without any apparent union or multiplication. The cysts of the flagellate, Giardi. sp., are reported for the first time in this host and occurred in 5% of those examined. Gray squirrels, hamsters, white mice, and a chipmunk were successfully infected with cysts obtained from a naturally infected squirrel. ln vitro cultivation of the trophozoites was partially successful. Cultures were maintained up to 21 days. In examinations for helminths, 3l of the hosts harbored adult cestodes of which two species were identified and 62% harbored nematodes of which 12 species were identified. From habitats designated "town, woodlot, forest fringes and remote forest," the highest incidence of nematode infestation occurred In the forest fringes sample. Nematodes were generally more prevalent among male squirrels than females and the average high incidence occurred during the spring. Numbers of worms per infection were generally higher in summer. The most common species were Citellinewa bifurcatum Hall, 1916. (45%), Strongyloides robustus Chandler, 1942, (28%), and Bohmiella wilsoni Lucker, 1943, (14%). The arthropod survey indicated 97% of the hosts were infested.Four species of lIce, two flies, one flea, one tick and six mites were reoovered. The greatest percentages of hosts infested, based on individual parasite species, were generally those collected during winter. The most common arthropods were Neohaematopinus sciuri Janoke, 1932, (81%). Orchopeas howardii (Baker, 1895), (74%) and Enderleinellus longiceps Kellogg and Ferris, 1915, (67%). Twenty-four adult squirrels (12 male. 12 female) were examined for total ectoparasites using a hair dissolving technique. Also the surface areas of those squirrels were calculated by body regions so that parasite densities could be determined. The results showed the highest densities generally occurred on the back, followed by legs, underparts, bead and tail. Parasite densities were generally greater on males. The preferences by the various species for certain body regions were determined from density data. A number of incidental arthropods were also encountered in these studies. Modified nest-funnels were constructed and placed in campus woodlots and monitored for a year. A list of the arthropod species occurring in these nests is given. Several new host records, a number of distributional records and one new species were evidenced in this study. / Ph. D.
