Soil labile organic carbon (LOC) is a valuable and sensitive parameter of the changes in soil (C) pools further affects structural stability. However, influences soil-aggregate stability on LOC fractions under erosion conditions are still unclear, especially collapsing gully area south China. Soils five positions erosion, including upper catchment (UC), wall (CW), colluvial deposit (CD), scour ...

abstract soil organic matter and its components are important factors in formation and stability of aggregates and subsequently soil structure. however data regarding organic matter distribution in soil aggregates is scarce, particularly in arid soils of central iran. the objective of this study was to investigate the distribution of organic carbon (oc), total nitrogen (tn), and carbohydrates i...

The objective of this study was to assess the impact of using heat-denatured whey:buttermilk protein aggregate in acid-set type yogurt production. Whey and buttermilk (25:75) protein concentrate was adjusted to pH 4.6, heated at 90 °C for 5 min, homogenized and freeze-dried. Set-type yogurts were prepared from skim milk standardized to 15% (w/v) total solids and 4.2% (w/v) protein using differe...

This paper presents parts of the results from a research project sponsored by Taiwan Environmental Protection Administration (TEPA), investigating both the physical and environmental properties of asphalt mixtures using different amount of incinerator bottom ash (IBA) as fine aggregate substitution. The Marshall mix design method was used to determine the design asphalt content and evaluate the...

This paper presents results of compressive strength, capillary water absorption, and density tests conducted on concrete containing recycled aggregate (RCA) which is obtained from structural waste generated by the construction industry in Turkey. In the experiments, 0%, 15%, 30%, 45% and 60% of the normal (natural) coarse aggregate was replaced by the recycled aggregate. Maximum aggregate parti...

recent tendencies in concrete technology have been towards to high- performance concrete with a low water-cement ratio. however, high performance concretes have some problems. one of the problems is early-age cracking due to autogenous shrinkage. this study presents the results of an experimental investigation carried out to evaluate the autogenous shrinkage of high-strength concrete. accordin...

The high performance concrete is a highly complex material that consists of cement, water, blast furnace slag, super-plasticizer, coarse and fine aggregate. All of the materials play a certain role in the compressive strength of concrete. Combined with the information about age, the compressive strength of concrete is determined by eight attributes: 1. Cement (kg/m!) 2. Fly ash (kg/m!) 3. Blast...

hydrothermal treatment of wood material products with many interesting properties such as enhanced dimensional stability, lower equilibrium moisture content and increased biological durability. the effects of hydrothermal treatment on dimensional stability, oven dry density and water absorption of beech wood (fagus orientalis) naturally grown, has been studied in present research that extremely...

although some 3d slope stability algorithms have been proposed in recent three decades, still role of pore pressures in three dimensional slope stability analyses and considering the effects of pore water pressure in 3d slope stability studies needs to be investigated. in this paper, a limit analysis formulation for investigation of role of the pore water pressure in three dimensional slope sta...
