The application of herbicides as organic chemical compounds to control pest and weeds may affect the population and activity of microorganisms, and this may have an influence on biochemical processes that are important for soil fertility and plant growth. The primary objective of this study was to evaluate different loading rates of eradican (EPTC) on soil microbial biomass C and N, microbial b...
T he present paper investigates the impact of the financial crisis on the interaction between the lending rates, deposit rates and money market rates through the process of retail bank interest rate pass-through in the countries of the Euro area. Among our findings is the heterogeneity of bank rate adjustments across sectors, loans and deposits. That was mainly marked during the pre-...
Nitrogen (N) is usually low in the majority of agricultural and non agricultural soils in Iran, mainly due to the lack of adequate soil organic matter (OM). On the other hand, boron (B) toxicity is becoming more widespread in arid and semi arid regions of this country, where soils or irrigation waters contain relatively high B content. Results of the research indicate that addition of certain p...
The nature of the relationship between the metabolic rate (MR) and body mass (M) of animals has been the source of controversy for over seven decades, with much of the focus on the value of the scaling exponent b, where MR is proportional to M(b). While it is well known that MR does not generally scale isometrically (i.e. b is seldom equal to 1), the value of b remains the subject of heated deb...
The importance of metabolic rate and/or spiracle modulation for saving respiratory water is contentious. One major explanation for gas exchange pattern variation in terrestrial insects is to effect a respiratory water loss (RWL) saving. To test this, we measured the rates of CO2 and H2O release ( and , respectively) in a previously unstudied, mesic cockroach, Aptera fusca, and compared gas exch...
Emerging Internet applications create the need for advanced packet classifiers. This paper investigates the mechanisms that determine the performance of state-of-the-art multi-field classification methods, and proposes a novel scheme called P2C for packet classification at OC-192 and OC-768 speeds. P2C combines the strengths of embedded memory and ternary CAM technologies to achieve very high s...
This paper gives an overview of the existing wireless network standards with their main usage, used frequency band, modulation, transfer speed as well as features and limitations. The main focus on this paper is an assistance to choose the best fitting protocol for an application. Therefore some typical scenarios for applications are described and after a preselection based on the main usage, t...
The diurnal fluctuation of nitrate concentration in the foliage of three parsley subspecies (plain-leafed, curly-leafed and turnip rooted parsley) cultivated in the spring and autumn of two consecutive years was examined. Nitrogen was applied at 30 (Control), 75, 150, 300 mg kg-1 in both years, but with the addition of 450 mg kg-1 in year 2. Harvest was carried out at 08:30, 12:30 and 17:30 on ...
The contamination of soils with lead is a major environmental problem throughout the world. Phytoextraction of heavy metals from contaminated soils has the prospect of being a more economic in situ alternative. Chemically enhanced phytoextraction has been proposed as an effective approach to remove heavy metals from contaminated soil through the use of high biomass plants. Using a pot experimen...
ABSTRACT-Application of models for simulation of solute and pollutants transport in soil can reduce time and costs for remediation process. HYDRUS-1D model was developed to simulate the one–dimensional flow of soil water, heat, solute and viruses in variably saturated–unsaturated porous media. The objective of this investigation is to determine the solute transport parameters in disturbed soil ...
