Dendroclimatologists often approach field work with the intent of reconstructing a particular climate variable (e.g. temperature, streamflow, precipitation). Although guidelines exist for species and site selection, isolating the signal of interest is difficult in areas with complex terrain or a lack of ideal sites. In this case study, I suggest climatological techniques for a more efficient sampling scheme and apply these techniques to identify criteria for selecting sites sensitive to winter precipitation in the north-central Rocky Mountains. These techniques include examining factors influencing the regional response of tree growth to climate by utilizing the International Tree-Ring Databank (ITRDB), using eigenvector analyses to identify modes of variability between sites, and delineating climate regions based on the variable of interest through climate regionalization. Results suggest that low- or mid-elevation Pseudotsuga menziesii sites should be targeted for maximizing the winter precipitation signal in the case study area. The season of precipitation impacting growth was found to be a major component of the overall variability between sites.

The Madden-Julian oscillation (MJO), also known as the 30-60day oscillation, is the strongest of the intraseasonal climate oscillations in the tropics and has significant derivative effects on extratropical circulation and intraseasonal climate. It has recently been shown that the stratospheric quasi-biennial oscillation (QBO) modulates the amplitude of the boreal winter MJO such that MJO amplitudes are larger on average during the easterly phase (QBOE) than during the westerly phase (QBOW). A major possible mechanism is the decrease in static stability in the lowermost stratosphere under QBOE conditions resulting from relative upwelling associated with the QBO-induced meridional circulation. Here evidence is presented that tropical upwelling changes related to the 11year solar cycle also modulate the boreal winter MJO. Based on 37.3years of MJO amplitude data, the largest amplitudes and occurrence rates, and the weakest static stabilities in the tropical lower stratosphere, occur during the QBOE phase under solar minimum (SMIN) conditions while the smallest amplitudes and strongest static stabilities occur during the QBOW phase under solar maximum (SMAX) conditions. Conversely, when the QBO and solar forcings are opposed (QBOW/SMIN and QBOE/SMAX), the difference in occurrence rates becomes statistically insignificant. During the coming solar minimum, at least one additional winter in the QBOE/SMIN category should occur (possibly as early as 2017/2018) during which especially large MJO amplitudes are expected and an initial test of these results will be possible. Plain Language Summary An ongoing issue in climate science is the extent to which upper atmospheric processes, including solar forcing, can influence tropospheric climate. It has recently been shown that an internal oscillation of the stratosphere, the quasi-biennial oscillation, can modulate the amplitude and occurrence rate of intraseasonal climate oscillations in the tropical Pacific during northern winter. These intraseasonal oscillations, the most important of which is the 30-60day Madden-Julian oscillation, have significant derivative effects on climate outside of the tropics, including impacts on rainfall events over the continental United States. Here evidence is presented that the amplitude of the Madden-Julian oscillation during northern winter is also modulated by the 11year solar cycle. The modulation is such that amplitudes and occurrence rates are largest under solar minimum conditions when the quasi-biennial oscillation is in its easterly phase and smallest under solar maximum conditions when the quasi-biennial oscillation is in its westerly phase. However, the available time record (37.3years of satellite measurements) is limited. During the coming solar minimum, at least one additional winter in the solar minimum/easterly category should occur (possibly as early as 2017/2018) during which larger-than-average amplitudes are expected and an initial test of the proposed relationship will be possible.

This work deals with the modelling of runoff processes in the experimental Bystřice river catchment in the Krušné Mountains. Rainfall-runoff model WaSiM (Topmodel version) was used for this purpose.Objective of this study was modelling snow accumulation and snowmelt in winter periods 2009/2010 and 2010/2011. Sensitivity analysis of TOPMODEL parameters was performed using Monte Carlo and GLUE methodology. Wasim was calibrated manually for 25 and 250 m grid scales and daily timestep. Results of simulations in both spatial scales different spatial scales differed significantly. Better performance of modelling in finer scale wasn't proved in validation of the model. Results of the simulations pointed out uncertainty in model calibration. Rasters of modeled snow water equivalent were also analyzed in selected days representing periods of snow accumulation and snowmelt. The goal was to examine the functioning of used snow model (combination of temperature index method and energy balance method) within the WaSiM frame. Finer scale raster proved to be practical for this purpose It was found that the spatial heterogeneity in the distribution of snow is determined by evapotranspiration and also by effect of radiation correction (in the case of rainfall).Influence of interception and vegetation effects on...

Title: Accomplishments of our cross-country skiing at the Winter Olympic Games Abstract: This thesis is focus on history of Czech and Czechoslovak cross-counrty skiing at the Winter Olympic Games from the first competition at WOG Chamonix 1924 to Vancouver 2010. Using the direct method and the method of content analysis it documents and summarizes the accomplishments of our cross-country representatives. It finds out that representatives of such a small country reached splendid results. But the available literature doesn't mention them as far as they didn't win a medal. Very interesting is the comparison between two skiing generations using the interview with their representatives Kveta Jeriova and Katerina Neumannova. The resulting comparison between their answers reaches a conclusion: the first of them had much harder conditions and worse facilities. In spite of this fact, she proved to be successful but her career was shorter and the number of medals smaller. Keywords: Winter olympic games, history, cross-country skiing, accomplishment

Doctor of Philosophy / Department of Agronomy / Dorivar Ruiz Diaz / Winter annual weeds (WAW) could affect nitrogen supply for corn production. The objectives of first study were to determine the diversity and abundance of WAW and to evaluate the effect of delaying herbicide applications on nitrogen supply and no-till corn response. Research was conducted in 2010 and 2011 at 14 sites in eastern Kansas. A factorial arrangement of three herbicide application dates (Nov.-Mar., April, and May) and five N rates were used. The three most abundant WAW across sites were henbit, purslane speedwell, and horseweed. Delaying herbicide application until April significantly reduced early corn N uptake by 52 mg N plant-1, chlorophyll meter readings at silking by 3.4%, and grain yield by 0.48 Mg ha-1 across sites. An additional 16 to 17 kg N ha-1 was needed to maintain yield if herbicide application was delayed until April. Starter and foliar micronutrient fertilization can potentially increase corn and soybean yield. The objectives of the second study were to evaluate crop response from combinations of starter and foliar fertilizers that contain N-P-K mixtures with and without a blend of micronutrients at four sites for each crop under irrigated conditions. No early corn growth or yield increase was attributed to application of micronutrients (Fe, Mn, Zn, Cu, and B) beyond what was achieved with N-P-K starter fertilization. There was an increase in soybean height (8 cm) and yield (293 kg ha-1) with starter fertilizer containing N-P-K plus micronutrients over the control. No increase in corn or soybean yield was obtained with foliar fertilization. The objective of the third study was to compare soil mobility and changes in soybean nutrient concentration in the leaf and seed from Mn and Zn sources (EDTA and oxysulfate) at two sites. Zinc sources were more mobile in the soil. Both Zn sources increased seed Zn concentration. Manganese oxysulfate increased seed Mn concentration. However, soybean trifoliolate leaf and seed Mn concentration decreased with soil-applied Na2EDTA and MnEDTA. This response was attributed to formation of FeEDTA and increased Fe supply that reduced root Mn absorption. Manganese EDTA is not recommended for soil application.

Four strangers are stranded in an old farmhouse by a winter storm. Gilley lives on the farm. Shadows move of their own volition on the farm, and Gilley talks to echoes and sees the dead reflected in mirrors. Gilley's husband, Frank, disappeared over forty years ago. Jason is a college student who seeks Gilley out for an interview. He agrees to help Gilley find Frank. Jesse is a young boy who finds his way to the house after an accident. August is a private investigator whom Jason calls for help in finding Frank. August does not have a shadow nor a reflection of his own, and he can't remember how he lost them. Each wants something that only the others can provide, but each wants to keep their own secrets.

This diploma thesis deals with contribution of chosen writings by Alois Jirásek and Zikmund Winter. It tries to clarify the term historism and its infiltration into Czech literature, particularly in novels Temno and Mistr Kampanus. The thesis also outlines the period after the Battle of the White Mountain. Its consequences dramatically influenced political, religious, social and cultural conditions in the Czech lands. It defines terms historical novel and historical short story to specify the border between this genre and the other proses of the then time. The practical part gives a concrete form of a complex interpretation of novels Temno and Mistr Kampanus. It introduces a dispute over historism between Alois Jirásek and Zikmund Winter. With the aid of content analysis of chosen readers for primary and secondary schools the thesis finds out the frequency of extracts by mentioned authors in schoolbooks. In closing the thesis focuses on evaluation of searched extracts in readers and mentions also FEP.

The main part of the thesis is evaluation of yield and qualitative parameters of hybrid winter rye. A small plot experiment was made at the Faculty of Agriculture of the University of South Bohemia in České Budějovice (380 m). The trial took place in two years: 2016/2017 and 2017/2018. The effect of sowing (early and late), seed quantity (standard - 2 MKS / ha and reduced - 1 MKS / ha), variety and year were evaluated in three varieties of hybrid rye (Cossani, Performer, Santini). To achieve the most accurate results, all 12 variants were sown in 4 replicates. From the qualitative parameters were determined: Falling number, volume weight, content of N substances. Concerning the yield, use of a standard seed rate (2 MKS / ha) was more stable, with an average yield increase of 0.64 t / ha. The most profitable was the Performer variety, which stood out with a consistently high falling number.
