Abstract:

Present paper addresses the climate regulating services provided by forest ecosystems in one of the most important protected area in Romania. Aiming to support decision making process in the matter of protected areas funding, the sequestered carbon quantities and values are presented using Sector Scenario Analysis approach - a comparison between business as usual and sustainable ecosystem management scenarios, applied on Vanatori Neamt Natural Park. A certain reduction in the wood harvested quantities can be at least partially compensated by accessing the opportunities of international carbon market.

Keywords:
protected areas, ecosystem services, carbon sequestration.

Abstract:

The research was carried out in the Iarac forestry nursery in the Iuliu Moldovan Forest District during 2012-2013, on an alluvial soil (the vertical-gleyed subtype). The placement of the sample plots was carried out according to the parcel in two repetitions, and the surface of a parcel was 450 m2.
The present paper displays the results obtained after the sprinkler irrigation, when we determined the quantity of water spread by the 7 sprinklers on a 15 m - radius, placed on the direction of the cardinal points.
The purpose of the research was to observe the correlation between the qualitative work indexes of the sprinkling devices, by spreading a uniform quantity of water on the entire surface and the maintenance of an ecological balance of cultivation of the saplings in the forestry nursery.
In a close connection with the purpose stated, the paper also focuses on the study of the work indexes of the sprinklers used in forestry nurseries, among which the most important is the uniformity of sprinkling.
The main means used for the improvement of sprinkling uniformity are the following: the usage of sprinklers with a small radius of sprinkling, having correct pluviometric curves; the correct placement of sprinklers on the terrain, according to the schemes of work recommended; avoiding to water when the speed of the wind surpasses the speed limit established for the sprinklers used.

Abstract:

Western Plain is one of the most affected regions from Romania by land degradations process. In the same time, this area is also vulnerable area to aridity and dought, having a low coverage of forests. Afforestation of degraded lands shows a lot of characteristics and numerous forms depending on field conditions. The researches during 2008-2012 had one of the purposes to establish the transpiration diurnal evolution, because it is very important in the seedlings growth and their vegetation stage. The experience acquired in the improvement through forest cultures for the protection of the degraded lands is very useful.

Abstract:

Mechanical control trough collecting and destruction of litter, in the autumn, must be supplemented by other measures during all growing season. One of these methods is chemical control, especially in parks with large areas, where mechanical method is inefficient (Lethmayer, 2005), or hardly to be applied. Abamectin 0.5% have better effect in controlling of the horse-chestnut leaf miner Cameraria ohridella. Good control it can be ensured with Lambda-cihalotrin 50 g/l and Acetamiprid 200 g/kg in addition with organosilicone adjuvant and repeat treatments after 2 weeks.

Keywords:

This paper deals with the results gathered from the control practices in the forestry nurseries on the two-year-old oak saplings, using portable spraying equipment (Stihl SR 420), when we sprayed three adjacent rows at a passage.
In the context of three rows sprayings, we determined the surface of the drops on a cm2, the number of drops on a cm2, the coverage percentage, the arithmetic mean of the number of drops on the eighteen sample markets and the total number of drops that fell on the top, the middle and the bottom of the sapling, both on the superior and inferior part of the leaf.

Abstract:

This paper presents the calculation of complementary food needs for animal species, which live in the hunting fund no.30 Valea Cernei. The calculation of food is absolutely necessary to be predetermined and properly distributed, so that in winter, the animals have required amount of food to survive, in order to develop and reproduce normally. Supplementary food is given only in winter, especially when snow prevents hunting to feed. Complementary food comes, as the name implies, to complement the very poor diet of the animals. The amount of complementary food is based on its quality of each species.

This paper covers the stages of setting-out the construction on the terrain. The required appliances are presented and also the staking and marking phases of the building contour and of the main axes. This paper also describes how to place the landmarks that are essential for vertical and horizontal angle measurement and other dimensions.

Abstract:

This article presents a costs analysis between two solutions: short drilled piles and direct foundation, on the same terrain, in the same building and exploitation conditions. The computations are based upon real data that were used in the execution of the work. To illustrate the advantages of the short drilled piles solution, a unitary length of the foundation (same load combination cases) was used in both situations. In conclusion, the short drilled piles solution is cheaper and easier to create.

The menu consists of all cooked foods, pastries, confectioneries and food products (that are served at a table).
Food is essential for man, providing the energy and substances needed for metabolic processes, growth and development, representing the regulator of exchange processes between the human body and the environment.
Food has always played a key role in human life, for both individuals and communities. Its qualities and deficiencies decisively influence one's health status. An adequate nutrition is essential for health and for the treatment of several diseases. It must be well-balanced from a quantitative and qualitative point of view.
