The Causes of Origin of the Cold War
Červenka, Jaroslav ; Calda, Miloš (advisor) ; Litera, Bohuslav (referee)
This bachelor's work deals with the reasons of the genesis of the Cold War. The work analyzes the reasons of the conflict during World War Two and the first years after. It's written about the first steps in the conflict, the diplomatic negotiations between the Soviet Union and western countries during the time of the problems at the end of the world war two, especially conferences of the Big Three, problems in Greece, Turkey and Iran. I analyze the steps to the cold war like the Truman doctrine and Marshall plan. The Soviet Union guilt is undeniable, but there is a lot of new information that shows blame of western countries, especially the United States. This is the reason why I write this work, this theme is absolutely not ended and slowly opening archives show a lot of new details about the start of the conflict. I want to compare the policy of both sides during world war two and first years after the end of the world conflict and find the problematic decisions of the western countries. I recognized that instead of the common opinion of the only guilt of the Soviet Union, we can find many problematic decisions from the Unite States contributed the beginning of the Cold War.

Dynamics of mountain spruce forest focused on natural regenaration development
Červenka, Jaroslav ; Svoboda, Miroslav (advisor) ; Tomáš, Tomáš (referee)
Disturbances have a major impact on the dynamic of forest ecosystems. However, there is lack of its exact consequences for mountain spruce forests in Central Europe. In 2007 heavy windstorm damaged a lot of stands in Šumava NP, subsequent bark beetle outbreak resulted in a large-scale dieback of spruce stands in this area. We took advantage of this opportunity. This study is focused on disintegration and structure of stands after the severe disturbance and in next step is focused on density and structure of natural regeneration in these stands. In addition we dealt with spruce regeneration (Picea Abies (L.) Karst.) on decaying logs. We compared two localities, disturbed (NP Šumava) and undisturbed site (CHKO Jeseníky). We concentrated on the change in saplings densities and on impact of decaying logs characteristic on this change. Finally we wanted to determinate impact of decaying logs characteristic on density of spruce regeneration. In area of Trojmezná we recorded 99 % mortality of parent stands. We founded only a few of adult tress which survived the disturbance, in addition we found several new trees, most of them with diameter about 10 cm. Live trees (DBH > 7 cm) reach density 16 trees per ha. The amount of dead wood was 2.5 times higher than before 10 years, one third were lying logs. Only natural regeneration of Norway spruce and rowan (Sorbus acuparia L.) was founded. Regeneration recruitments occurred in sufficient numbers, mostly on mosses (32 %), dead wood (27 %) and the nearest neighbourhoods of living mature trees or snags (28 %). Advance regeneration occupied 88 % of all regeneration. The density of individuals was similar along the elevation gradient. But in lower elevation of study area was situated higher regeneration recruitment then in the higher parts. With increasing elevation gradient regeneration was more homogenous in height and was lower. Best conditions for spruce regeneration provides logs with the largest diameters and logs with presence of white fungi Armillaria spp. or Phellinus nigrolimitatus. On the other hand logs with presence of Fomitopsis pinicola do not provide a suitable microsite for saplings. When we compare change in regeneration density on dead wood between the disturbed and undisturbed site, our results show significant increase in regeneration density at disturbed site (by 33 %). The increased regeneration density observed at the disturbed site was mostly associated with the smallest saplings on logs with the largest diameters. Three years after death of the parent stands no significant effect was recorded on the growth rate and survival of established spruce saplings on dead wood.

Výzkum možností aplikace norem DIN 18915-20 (Technologie vegetačních úprav v krajině) do systému norem ČSN
Výzkumný ústav Silva Taroucy pro krajinu a okrasné zahradnictví, Průhonice ; Červenka, Jaroslav ; Bulíř, Pavel
Soubor sedmi německých norem DIN 18915-20:2002, které byly přeloženy do češtiny, odborně upraveny a opatřeny národními poznámkami pro podmínky ČR. Tyto návrhy jsou dále technicky upraveny podle pokynů ČSNI Praha tak, aby mohly být po schválení převzaty jako ČSN DIN 1891. tyto normy řeší okruh technologií vegetačních úprav v krajině počítaje v to i sídla. Konkrétně standardizují práce s půdou, rostliny a jejich výsadby, zakládání trávníku, zajišťování terénu biotechnickými metodami, rozvojovou a údržbovou péčí o vegetaci, a také ochranu vegetace a ploch pro vegetaci při stavebních činnostech.
