Posouzení vhodnosti použití harvestorové technologie lesní těžby na ŠLP Křtiny

Sysel, Jan January 2015 (has links)
This thesis is focused on assessing the suitability of using harvesting technology in conditions of Training Forest Enterprise Masaryk Forest Křtiny (TFE). The work is related to the overall characteristics of harvester technologies in terms of technical solutions, but also to establish criteria of suitable natural conditions for the most thrifty deployment. The findings obtained in this investigation are applied to the forests of the property to discover the potential using options of harvester technologies. Criteria to determine the suitability of the forest stand were: type of terrain, edaphic category, minimum representation of conifers and age of stand. For forest stands there are assigned the appropriate types of harvester chassis and harvester heads which are suitable for their cutting. In the thesis there are further processed optimal harvester nodes, a comparing of the time consumption to processing of the volume of logging by classical logging technologies and harvester technologies. Based on the findings there was elaborated a recommendation for operating practices.

Vliv šířky pracovního pole plně mechanizovaných technologií na zpeněžení dříví stanovený na základě sortimentace - případová studie na ŠLP Masarykův les Křtiny

Kyselý, Martin January 2015 (has links)
There was the field investigation carried out at Habrůvka forest district in eight Norway spruce (Picea abies (L.) dominated forest stands from 4th to 11th age class. Based on the survey data the individual stems were notionally split into parts, assorted, classified into quality grades and valued according to average prices on the timber market for 2013. The results of assorting clearly show the difference between the expected realization of the trees along the forest tracks and from the inside of the forest stand, where trees from the inside achieve higher values. Subsequently, the evaluation of two basic forest infrastructure schemes was conducted, as the more forest tracks, the larger area affected and the higher number of the trees with lower expected value occurs. In terms of yields from the forest stand the variant with wider working fields seems more profitable, even though different technologies have to be applied.

Vývoj a růst lesních kultur pocházejících z krytokořenné a prostokořenné sadby / Growth performance of containerized and bare-rooted planting stock

Pechman, Petr January 2016 (has links)
The aim of this thesis is to analyze the development and growth of containerized and bare-rooted seedlings of Norway spruce on the plots situated on the Dolní Lomnice Forest District, a division of Karlovy Vary VLS ČR, s. p. (Army Forest and Estates of the Czech Republic). In this work addressed the following sub-tasks: comparison of mortality, height increment and increment of root collar, root development, analysis of cost recovery stands on the site. Three years after the founding of the plots it was discovered that containerized planting stock reached higher relative increment. When using a planting hole technology, the mortality was in both types of planting stock approximately similar. Furthermore, it was found that containerized planting stock planted with the planting hole technology, a higher incidence of advent naturally developed roots occurred. The planting technology using a loading mandrel (similar typesetter) used for containerized planting stock was assessed as an unsuitable and also the most frequent presence of unnatural root architectonics (deformations and secondary roots, if they were ever developed) it was demonstrated. An economic study showed that the overall costs for the forest regeneration using of the containerized planting stock are higher compared with the bare-rooted planting stock.

Využití půdoochranných technologií v pěstování řepy cukrové / Use of soil conservation technologies in the growing of sugar beet

Hybler, Jakub January 2016 (has links)
More recently we meet with many extremes of weather. One such are sudden and heavy rainstorms. Now most these rains endanger the agricultural land the emergence of water erosion. Most sensitive to water erosion are wide row crops, including sugar beet also. For these reasons, in recent years we paid great attention to the impact of tillage effects on soil water erosion. The aim of this thesis was evaluate the influence of autumn tillage on water erosion soil in the stand of sugar beet, but also on the yield and quality parameters of the crop. A secondary aim was to assess the effect of increasing the leafy ground cover beet on water erosion soil. For this purpose over the years 2012-2015 based on accurate field trials on lands Agro Chomutice Inc. Experiments were set up in three variants namely shallow loosening (10 cm) deep plowing (25 cm) deep loosening (25 cm). In various growth phases proceeds artificial rainfall. In the first growth phase was not sugarbeet involved either in row and not in the between rows. In the second growth phase of the beet involved in the row between rows but not yet. In the third growth phase has been fully involved growth. Itself artificial rainfall was performed field simulator rain and was observed soil loss from individual variants. At artificial rainfall it was found that sugar beet is the most threatened by water erosion soil in the early growth phase and at this phase the most evident difference autumn tillage to sugar beets. In the first growth phase of sugar beet, which was carried artificial rainfall, the best results both for deep loosening and deep plowing. In 2012 (24. 5. 2012) was measured with a deep loosening of soil loss of 1.30 t ha-1, representing a decrease of 64.76% compared to the shallow loosening and by 40.91% compared to deep plowing. Conversely, in 2014 (2. 6. 2014) was evaluated as the best variant of deep plowing the soil loss of 0.11 t ha-1. Such loss soil is 78.43% less compared to the deep loosening and lower by 91.41% compared to the shallow loosening. Similar results were achieved for both deep loosening and deep plowing in the later phases of growth, which was carried artificial rainfall. From the results it was found that the sugar beet at later growth phases better resists water erosion. This is illustrated in 2012, when the first artificial rainfall (24. 5. 2012) was observed soil loss of 2.20 t ha-1 for deep plowing. In the second artificial rainfall (6. 6. 2012) 0.03 t ha-1, and the third (1. 8. 2012) have been measured zero loss soil. The same results were achieved in the following experimental years. On deep loosening achieved the largest root yield (99.71 t ha-1), but the difference between deep plowing (99.32 t ha-1) was only 0.39%. The highest sugar content reached variant with deep loosening (18.95%). When the statistical treatment has not been established between the variants statistically significant difference. The greatest yield root recalculated at 16% sugar content reached variant with deep loosening (122.32 t ha-1), but again the difference between deep plowing (119.81 t ha-1) was only 2.10%. Results from four years has clearly demonstrated beneficial effect of deep loosening and deep tillage on soil water erosion in the sugar beet crop. Furthermore, it was found that with increasing abundances leaf and root growth of sugar beet decreases danger of water erosion. Sugar beet is the most susceptible to water erosion in the early phases of growth, and at this time was applied deep autumn tillage. For a fully wired vegetation were not detected significant loss soil, and at this time ceases to be a dangerous erosion sugar beet crop. For yield and quality parameters of sugar beet was found positive effect of deep loosening and deep tillage on yield and quality of sugar beet. The least favorable results in all experimental years was achieved in a shallow loosening.

Vliv vnějších činitelů na výskyt mastitid u dojnic / The influence of external factors on the incidence of mastitis in dairy cows

Valíčková, Daniela January 2016 (has links)
The aim of this diploma work was to evaluate the influence of a farm, a lactation order, and a month and a year of calving to the percentage occurrence and number of mastitis with cows. Besides, mainly an effectiveness of precautions, nursing works and farming technologies were evaluated. The evaluation was being performed during the years 2014 - 2015 at two farms situated in Slovakia which were breeding the breed of Slovak piebald cattle. Figures about the mastitis occurrence were acquired from the evidence of veterinary records of mastitis treatment and cows´dry out. Information about the number of somatic cells I have borrowed from Slovak republic breeding information system. For the figures evaluation a statistical program SAS 9.3 (SAS/STAT 9.3, 2011) was used. For the determination of basic parameters the procedures MEANS a UNIVARIATE were used. Observed indicators and basic statistics were evaluated for both arms together. Main parameters were evaluated statistically for both farms altogether. From the total number of 514 milk cows, was the mastitis occurrence recorded on the average in 29,77%, with the average length of treatment 1,94 days and milk cows´ lactation was on the average 2,81. The number of mastitis occurrence was on the average 0, 51 times, the highest frequency of mastitis occurrence achieved up to 6 times. Statistically significant influence of mastitis numbers to the percentage mastitis occurrence (P <0, 001) was proved. Percent of mastitis occurrence is provable influenced by a farm (P<0,001), a year and a month of calving (P<0,001) and lactation order (P<0,001). The number of mastitis is considerably influenced by a farm (P<0,001), a month and a year of calving (P<0,001). Percent of mastitis occurrence reached the highest figures on the 5th and the next lactation (68, 49 %) and the lowest % mastitis occurrence was recorded on the 1st lactation (45, 98 %). The number of mastitis occurrence was the highest on the 5th and the next lactations (1,19x) and the lowest on the 1st lactation (0,81x). Percent of mastitis occurrence was during the observed period higher at the farm PD Mestečko (66, 06 %) and the lowest at the farm PD Dolná Mariková (48, 96 %). Demonstrability on the boundary of statistic difference´ importance (P < 0, 01) was between % mastitis occurrence and both farms. The number of mastitis occurrence was higher at the farm PD Mestečko (1,22x) in contrast to the lowest at the farm PD Dolná Mariková (0,82x). Statistically proved difference (P < 0, 01) was between the number of mastitis occurrence and the farms PD Mestečko and PD Dolná Mariková. Percentage mastitis occurrence was the highest in April (79, 05 %), the lowest occurrence was in November (34, 30%). The number of mastitis occurrence was the highest in March (1,51x), the lowest was recorded in November and December (0,63x). The highest percentage mastitis occurrence (99, 92 %) was recorded in calving year 2013. The lowest mastitis occurrence was in year 2015 (19, 92 %). The number of mastitis occurrence was the highest in year 2013 (1,92x) and the lowest in year 2015 (0,33x).

The Impact of Information and Communication Technology (ICT) on Economic Growth &#8211; The Case of Selected Arab Countries / The Impact of Information and Communication Technology (ICT) on Economic Growth &#8211; The Case of Selected Arab Countries

Hodrab, Rami Mohammad Awad January 2016 (has links)
Information and communication technology (ICT), population growth, gross capital formation, Openness, labour and inflation are frequently well-thought-out as important drivers of economic growth for all countries, so as for Arab countries in our case. This study aims to examine the effect of these factors on 18 selected Arab countries economic growth, covering the period from 1995 to 2013, with the main interest of the impact of ICT. The results show positive and significant impact of ICT index (infodensity that represents the capital and labour stock of ICT) for each individual country (except for Djibouti with negative ICT index elasticity and UAE with insignificant impact) ranged from 0.10 for Lebanon to 0.469 point for Qatar. The panel regression results show that ICT positively and significantly affect the whole sample of 18 Arab countries economic growth with 0.108 point, as well as GCF ratio with 0.129 impact, in addition to openness which encounters positive and significant impact with 0.054 point, and inflation with negative significant impact. These results are accommodated with many related studies. Population growth is insignificant to economic growth. The 18 Arab countries are divided into three sub groups according to their infodensity levels. The research results show that there is a relatively large gap between first and second groups of high and intermediate infodensity values in one side and the third group (with low infodensity and GDP per capita values) on the other side. In order to verify further the results of positive and significant impact of ICT on economic growth, a second study model that depends on Cobb-Douglas production function is applied with ICT and non-ICT capital services and labour services. This second model is applied on five Arab countries that covers the period from 1993 to 2014 using ARDL method. The regressed results show a long run equilibrium cointegrated relationship between ICT and non-ICT capital services, in addition to labour services and GDP growth. The results tell a positive and significant elasticity of ICT capital services at short and long run, and this value is more than the ICT capital services compensation share, which indicates ICT spillover in these Arab countries. Labour services impact on GDP growth is positive and significant on long run, but for non-ICT capital services, there is a negative and significant impact. So finally it is worth for the Arab countries to invest more and efficiently in ICT assets, in addition these countries have to efficiently use the available ICT resources.
