LAND CONSOLIDATION AND ENVIRONMENTAL PROTECTION

(SGEM Scientific GeoConference, 2008, Ivkovic, Mira, Dzapo, Marko, Vihra, Ana)

Show more

Rural area of Croatia covers 90\% of land in Croatia, and there 47\% of total population living in it. These are mostly poorly developed areas in Croatia, and they are being expanded all the time, which causes the emigration of population. In order to trigger the development of rural areas, some measures are planned, among other things the land consolidation that might increase the economic efficiency of family farms, and hence, prevent the emigration of population from villages. Namely, small family farms being l...

Many countries has used the wind energy for agricultural pumping water for many years. Mechanical energy or electrical energy which is converted from the wind energy drives the pump. Water is not directly convey the target areas due to discontinuous wind regime. Therefore water is conveyed the storage tank. In addition, using the drip irrigation system at this system is provided saving at the agricultural economy. The increasing use of wind energy instead of the fossil energy provides to decrease pollutant emissio...

In this study, removal zinc from aqueous solution was studied using smectite-bearing soil. The effects of initial Zn(II) concentration, pH, adsorbent dosage, and contact time were investigated. When the initial concentration of Zn(II) was incresed from 0.7 to 3.77 mM, the Zn(II) removal efficiency decreased from 100\% to 90.7\%. To determine the effect of pH on the adsorption efficiency of Zn(II), pH was varied between 3.0 and 7.0. The sorption efficiency of Zn(II) onto soil seems to be independent of pH with in s...

Biogas is a part of the natural circle. Biogas is formed by the activity of anaerobic bacteria. In nature biogas is produced for example in bogs. It is also possible to produce from biological material in an environment free from air. The gas that is produced is methane (CH4), which is an excellent fuel for heat, electricity, and cars that doesn’t drain the earth’s fossil resources. The raw-material in biogas production has traditionally been waste from the food industries, and communal sewage treatment works. Bio...

POSSIBILITIES OF UTILIZATION OF SLAGS FROM METALLURGICAL PROCESSES

(SGEM Scientific GeoConference, 2008, Frohlichova, Maria, Baricova, Dana, Demeter, Peter)

Show more

Smelting of hammerable iron and its treatment in Antiquity and Medieval produced also by-product: slag. Because of small yields of iron the process produced only small amounts of slag that did not attract attention of smelter concerning its possible use. The use of slag pieces was only accidental. The paper deals with the most important processes used for treatment of blast furnace and steelmaking slags and with the most important ways of their utilization. The method of recycling of steelmaking slags, that follow...

THE DYNAMIC OF MYCORRHIZAL FUNGI IN FOREST COMMUNITIES FROM GIUMALAU MOUNTAIN – EASTERN CARPATHIANS (ROMANIA)

(SGEM Scientific GeoConference, 2008, Birsan, Ciprian Constantin, Tanase, Catalin)

Show more

The investigated area has about 200 sq km and it is situated in the north of Eastern Carpathians. Our researches have been carried on samples at an altitude range between 700- 1800 meters a.s.l. There have been identified 4 forest communities: Calamagrostio villosae – Pinetum mugi Sanda et Popescu 2002, Hieracio transsilvanici – Piceetum Pawlowski et Br.-Bl. 1939, Hieracio transsilvanici – Abietetum (Borhidi 1971) Coldea 1991, Leucanthemo waldsteinii – Fagetum (Soo 1964) Tauber 1987. The goal of this study is refe...

BRAILA PLAIN - IMPLICATIONS OF WATER RESOURCES QUALITY ON ENVIRONMENT

(SGEM Scientific GeoConference, 2008, Turtureanu, Anca Gabriela, Tureac, Cornelia Elena)

Show more

A significant element characterizing a lasting development in Braila Plain region, but also in any other similar area, would be an environment factor i.e. the water, with an increasing importance when considered against the high dryness background. Generally speaking, both the consumed water and the consumption structure reflect the quality and quantity of water resources and, implicitly, the economic potential of the region at issue. As for Braila Plain, here there is a paradox to be considered : even if the regi...

BRAILA PLAIN - RESOURCES MANAGEMENT

(SGEM Scientific GeoConference, 2008, Turtureanu, Anca Gabriela, Tureac, Cornelia Elena)

Show more

The climate, morphometric and lythological conditions confer certain peculiarities upon the waters resources of the northern-eastern Romanian Plain. One can say about the Braila Plain hydrographic network that it is poor and this is due to the discharge, situated under the value of 1 l/sqkm, but also to the very low relief energy. The allochthone rivers : the Danube, Siret, Buzau and Calmatui are affected by the refief climate conditions and also by the size and the geographic position of the hydrographic basins.

OFFSHORE PIPELINE VORTEX SHEDDING ANALYSIS

(SGEM Scientific GeoConference, 2008, Chis, Timur)

Show more

This study aims to ensure the offshore pipeline under offshore vortex shedding analysis. Optimizations process depending on the iterative procedures requires an analysis considering each of extreme condition on the internal and external pipe flow. The stabilization of the offshore pipeline on sea bottom exposed to wind-generated wave and uniform-steady current action is achieved by utilized artificial concrete weights and sliding resistance between pipe and soil. Additionally, the vortex shedding induced dynamical...

TREATMENT OF COD WITH REMOVAL OF DICHLOROMETHANE AND CARBON TETRACHLORIDE IN THE WASTEWATER WITH UASB

(SGEM Scientific GeoConference, 2008, OZDEMIR, Celalettin, Sen, Nejdet, Dursun, Şukru, Tezcan, Hayrunnisa)

Show more

Low concentration of chlorinates maybe found in wastewater, contaminated soils and air due to different industrial sources. Low level of Volatile Organic Compounds (VOC)’s could be removed by adsorption, incineration and biofiltration methods. These methods have some disadvantages such as removal efficiency or high operation cost. Chlorine has been removed from the chlorinated aliphatic compounds under anaerobic conditions. The aim of this study was to investigate biological treatment of DCM and CT in high flow sp...
