بررسی منشأ و تغییرات کربن آلی محلول ( DOC) در منابع آب
امروزه می توان با اندازه گیری کربن آلی محلول ((DOC، که به عنوان یکی از شاخصهای عمده ی کربن محلول در آب محسوب می شود، به بررسی میزان تغییرات کربن آلی محلول در منابع آبهای سطحی و زیرزمینی و منشأ کربن پرداخت. DOC همچنین به عنوان یک آلاینده در منابع...
Elevated CO2 and nitrogen effects on dissolved organic carbon of two calcareous and non calcareous soils
Abstract
Dissolved organic carbon (DOC) pools can be considered as suitable indicators of soil quality that are very sensitive to different soil management practices. In this research controlled chambers were used to investigate the effects...
Effects of drying and rewetting on dissolved organic carbon (DOC) of two alfisols in the north of Iran
and rewetting cycles was investigated on two different soil samples collected from north of Iran. The results showed that different soil samples had different DOC concentration and it was decreased by drying and rewetting cycles in both soils....
Examining the Effects of Google Docs-Based Instruction and Peer Feedback Types (Implicit vs. Explicit) on EFL Learners’ Writing Performance
in different instructional models (Google Docs/ F-to-F). The findings of this study revealed the importance of Google Docs-based writing instruction in increasing students’ confidence in their writing skill abilities and their willingness to allow others...
Compound specific Isotopic Analysis (CSIA) of landfill leachate DOC Componets
In an attempt to better characterize the biogeochemical evolution of dissolved organic carbon (DOC) in landfill leachates, and to interpret the origin of DOC in groundwater, we have developed a new analytical technique for the compound specific...
Application of 13C isotope and carbon geochemistry to identify impact from landfill on surrounding groundwater
In this paper, thed3C values and concentrations of carbon pools (DOC, DIC, CH4 and acetate) were
used to recognize leachate impact on the surrounding groundwater and to evaluate carbon
biogeochemistry within the Ottawa landfill plume...
