… using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the …
… forest stands from the about same geographical location. The effects of precipitation, temperature and frost on the year ring characteristics of pine were studied in the research forest of Svartberget Vindeln, in northern Sweden. The stands differed in site index and …
… a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland. The high precipitation could be a consequence of climate changes. Increased …
Analys av klimatgr?nser och framtida klimathot
… future climate. The results showed that the climate is becoming warmer, and precipitation is increasing, both in prolonged periods and shorter, more extreme periods, which will be challenging for the majority of the already planted urban tree species. This forms the basis for …
… and higher sea surface temperatures (SST) leading to rising air and anomalous precipitation in eastern Pacific constituting the El Niño phenomenon. My outermost interest regarding El Niño has been the associated teleconnections, especially in nontropical areas. I have described …
… has been measured on five different occasions. The spring of 2002 had a lot of precipitation and the meadows were flooded during long periods. The floods were relatively evenly distributed over the meadows. Water was mainly concentrated around ditches and in the northern part of …
… of Småland. Influence by variables such as chloride deposition, amount of precipitation, site index, and age were examined. The results showed that the mean chloride concentration in Norwegian spruce within the study area was 28,6 mg Cl- /kg dry weight substance in the wood …
… with respect to natural background, variation in time, correlation with precipitation, depth and other measured parameters. Geochemical modelling using the computer code PHREEQC has also been conducted. The waste of the minefields at Gladhammar is constituted of waste rock, slag …
En teknisk/ekonomisk utvärdering av reningsmetoder för metallhaltigt avloppsvatten
… plating factory inEskilstuna. Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste …
… a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge. The solution can then be recycled to use on farmland. The disadvantages of the RO technology include high energy consumption and sensitivity to membrane …
… using the program Visual MINTEQ were performed in order to assess the role of precipitation as a mechanism for removal. The results show that the blast-furnace slag was the most effective filter material and that it has great potential to be used as a heavy metal remover. Also …
… sludge process and to recycle phosphorus, experiments with phosphorus precipitation were made. By using struvite precipitation up to 92 % of the phosphorus in the supernatant was reduced and precipitated. This was 12 % of the total amount of incoming phosphourus and was achieved …
… element analyses of this material, indicated an ongoing process of biochemical precipitation of iron oxides conducted by iron oxidizing bacteria in the lake and the main stream. The observed phenomenon is probably connected to natural presence of iron in the specific area and to …
förslag till anläggning för ekologisk hantering samt metodöversikt
… for storm water disposal. That is as long as water flows are moderate. But precipitation varies naturally in amount and intensity and additional impermeable surfaces make some pipes insufficient for heavy or lasting precipitation. Poor infiltration will in the long run disturb …
Vilka faktorer ger elever motivationoch lust att lära matematik?
… steps which are most important to maintain the treatment process are chemical precipitation followed by rapid filtration, slow filtration and disinfection with chlorine. If any of these cleaning steps were to fail, this introduces a large increase in the risk of waterborne …
