Relativistic corrections for the vibration-rotation levels of the ground electronic state of the hydrogen molecular cation H-2(+)
No full textPrevious work [Moss, R. E., and Valenzano, L., 2002, Molec. Phys., 100, 649 and 1527] on the non-adiabatic properties of the vibration-rotation levels of the ground electronic state of the hydrogen molecular cation is extended to the calculation of relativistic corrections. Unlike the earlier calculations, in which all matrix elements were evaluated analytically, numerical methods are needed for some of the integrals
Morphogenesis in the moss physcomitrella patens
No full textA method was developed for recording the development of moss protonema using time-lapse video microscopy. This has provided a detailed record of the time-course of development from spore germination to the production of gametophores. Detailed records of the growth of primary and secondary chloronema, the transition of primary
chloronema to caulonema, and the development of side-branches were obtained. Filaments were found to undergo the transition to caulonema earlier than previously
thought. The majority of caulonemas ide-branches were found to begin as chloronema and switch to caulonema after one or two cell cycles. The early cell divisions of bud
formation were found to follow a distinct pattern, which was upset by high concentrations of cytokinin and lanthanum. The response of caulonema apical cells to
polarotropic light was recorded and compared to the gravitropic response.
The time-lapse studies provided the basis for the further development of the quantitative analysis of protonemal branching patterns to include second and third
side-branches of a sub-apical cell, and transitional caulonema. Analysing side-branch patterns should allow the detection of developmental mechanisms underlying the
determination of side-branch fate. The potential of this method for assessing the effect of hormone treatments and for analysing more precisely mutant phenotypes was
explored. An analysis of bud spacing was carried out to determine if the formation of a bud on a filament was inhibitory to other buds forming on the same filament. It was found, to the contrary, that buds tended to form in clusters.
The hypothesis that the primary mode of action of cytokinin is an enhanced influx of calcium ions into the cell was investigated. Classical electrophysiology was used in
order to detect any change in membrane potential suggestive of ionic fluxes in response to cytokinin treatment. No definitive changes in membrane potential were detected in response to cytokinin. This appeared to rule out the involvement of voltage-regulated channels in cytokinin action. The effects of some inhibitors used in
studies of calcium on the moss protonemal system were examined. It is suggested that the concentrations commonly used had toxic effects that were not specific to calcium
channels. The ionophore A23187 was used to characterise the protonemal response to a sustained influx of calcium. Some mutant strains were found to have a differential
response to the ionophore. This may mean that they have mutations affecting their calcium regulatory system.
Two new techniques of imaging calcium were used in order to detect changes in intracellular calcium in response to cytokinin. A method was developed for loading the dual wavelength fluorescent dye Indo-1 into moss protonema using iontophoretic microinjection, and intracellular calcium was imaged using ratio-image technology. Wild-type moss and some mutant strains were also successfully transformed with the gene for apoaequorin, and calcium luminescence measured in response to cold-shock and plant hormones. Some different responsesto temperatures hock were apparent in
one of the transformed mutants. Preliminary experiments did not reveal any aequor independent calcium luminescence in response to cytokinin

U-1456 to U-1464In this series of 8 interviews, Senator Moss (b. 1911) recalled his childhood growing up in Salt Lake County, his father, a noted Utah educator James E. Moss, his education in the public schools, at the University of Utah and later George Washington Law School, his marriage to Phyllis Hart, his work in Washington prior to WWII, his army service in WWII, his career as Salt Lake County Attorney and later as a judge, his entry into Democratic politics and winning the race as United States Senator, a position he held from 1958-1976. He listed his major accomplishments in the senate as the work he did on behalf of Utah water projects, creating national parks within the state, Great Salt Lake assistance, and banning television advertising for tobacco products. He discussed his activities since leaving the senate which included association with some law firms, his love of travelling and spending time with his family. Included with the interviews is an 18 page personal history that details his many accomplishments. Interviewer: Everett L. Coole
Gradsteinia andicola : a remarkable aquatic moss from South America
No full textA new moss genus and species, Gradsteinia andicola, is described from the northern Andes of Colombia. It is an aquatic moss known sterile and characterized by 1) oblong or oblong-ovate, concave, cucullate and recurved-apiculate leaves with a very strong and variable costa that is basically single but commonly repeatedly branched and spurred from the base, giving the leaves a polycostate appearance; 2) thick-walled, porose and irregularly uni- to multistratose lamina cells; 3) bicellular axillary hairs; 4) the presence of incomplete limbidia; 5) the absence of paraphyllia, pseudoparaphyllia, central strand and alar cells. Until the sporophyte of Gradsteinia becomes known, this very distinct genus is tentatively placed in the family Donrichardsiaceae, based primarily upon the presence of variously multistratose leaf laminae and leaf areolation
Adiabatic and non-adiabatic corrections to properties of the hydrogen molecular cation and its isotopomers: dissociation energies and bond lengths
No full textA study is presented of adiabatic and non-adiabatic corrections to the dissociation energies and bond lengths of H-2(+), D-2(+) and HD+ in vibration-rotation levels of their ground electronic states, with particular attention to isotopic scaling. In previous work (Moss, R. E., 1999, Molec. Phys., 97, 1) on rotationless levels, an anomalous non-adiabatic correction to the bond length was found for v = 20, N = 0 of HD+. Other levels close to dissociation are identified that display anomalous non-adiabatic corrections to the dissociation energies and to the bond lengths. The source of these anomalies is discussed

An ecophysiological study on the moss hydrogoniuh fontanum from the Asir mountains, Saudi Arabia
No full textThe thesis describes a study on the ecophysiology of the moss Hydrogonium fontanum (C. Mail.) Jaeg., the dominant plant at a waterfall in Saudi Arabia. The influence of environmental variables and water stress on the growth, stress metabolite accumulation and phosphatase activities of the moss was studied in laboratory axenic culture along with observations and experiments conducted in the field. The variables chosen for growth experiments were light flux, flooding, nutrient concentrations and water stress. For phosphatase activities, the influence of temperature, pH, ions, water stress were studied. Differences were found in phosphatase activities for rhlzoids, protonema and leafy shoots of the moss and, therefore, the phosphomonoesterase (PMEase) and phosphodiesterase (PDEase) activities of these fractions were also investigated. H. fontanum was originally collected from the tufa-depositing waterfall (Water chemistry - 44 mg 1(^-1) Na, 44 mg 1(^-1) Ca). High Na and Ca had significant positive effect on yield of the protonema under the laboratory conditions. Low light intensity (10 µmol photon m(^-2) s(^-1)) decreased the yield, but high light intensity (90 µmol photon m(^-2) s(^-1)) increased the yield of the protonema. The moss showed no response to water stress in respect to praline accumulation. Protein content decreased significantly over 48 h with increase in water stress. The Influence of water stress was greater in terms of dry weight and chlorophyll content changes in protonema than in leafy shoots. The protonema was capable of using various organic P substrates as sources of phosphorus and showed both PMEase and PDEase activities. PMEase and PDEase activities were detectable in all moss fractions (rhizoids, protonema, leafy shoots). Laboratory grown material showed higher activities than field grown material. Rhizoids produced the highest PMEase and PDEase activities among the moss fractions. Some leafy shoots collected from the field had low phosphorus content with high phosphatase activities, while others had high phosphorus content with low phosphatase activities. Changes in phosphatase activities in batch culture were studied in relation to growth rate. PMEase activity was first evident when cellular P was 1.15% with low activity (0.117 µmol pNP mg d. wt(^-1) h(^-1)) and PDEase appeared 4 days later when cellular P was 0.54%. The activities increased up to day 12 after which the activities maintained this level. The optimum temperatures, measured over a period of 1 h, for PMEase and PDEase activities were 60 ºC and 65 ºC with pH optima of 5.5-6.0 and 6.4-6.8, respectively. Of the six ions tested, Ca, Zn and P had significant inhibitory effects on the activities at the highest concentration used (10 mM).Drying the moss decreases PMEase and PDEase activities by about 23% and 21% (5-d) and 3.7 and 2,8 times (3 months), respectively. Water stress (PEG treatment) also reduced significantly the activities of PMEase and PDEase with a greater effect on the activity of the latter. A brief comparison in PMEase activity using two different substrates p- nitrophenyl phosphate (pNPP) and 4-methylumbelliferyl phosphate (4-MUP) was made to investigate the pH optima and time course. PMEase activity measured using 250 µM 4-MUP was about 60% of that measured using the same concentration of pNPP
