Nowadays, enhanced oil recovery is vital in improving the recovery. However, productions keep depleting due to production problem such as high surface tension and interfacial reservoirs. Therefore, chemical flooding one of methods used The synergy between Silica nanoparticle Sodium Dodecyl Sulfate has been proposed a compound for this project. major aim study was measure effectiveness synergiza...
The objective of this paper is to establish relationships between rainfall extremes and damage data from Dutch insurance industry. Rainfall data are based on a network of 33 automatic rain gauges held by the Royal Netherlands Meteorological Institute. Rainfall characteristics, such as peak rainfall intensity and rainfall volume, are correlated with damage statistics of claims in the vicinity of...
Flooding stress has a negative impact on soybean cultivation because it severely impairs growth and development. To understand the flooding responsive mechanism in early stage soybeans, a glycoproteomic technique was used. Two-day-old soybeans were treated with flooding for 2 days and roots were collected. Globally, the accumulation level of glycoproteins, as revealed by cross-reaction with con...
BACKGROUND AND AIMS Flooding can occur at any stage of the life cycle of a plant, but often adaptive responses of plants are only studied at a single developmental stage. It may be anticipated that juvenile plants may respond differently from mature plants, as the amount of stored resources may differ and morphological changes can be constrained. Moreover, different water depths may require dif...
Rice bran application just after transplanting has been increasingly practiced as a herbicide-substitute for organic rice production in Korea. However, this practice is frequently reported to be unsatisfactory in weed suppression. An experiment with five treatments that combine flooding depth (shallow and deep), rice bran application level (low and high), and herbicide application was carried o...
This study sought to probe the role of input flooding through listening tasks on the uptake of simple present tense and the present progressive tense among pre - intermediate English a s Foreign Language ( EFL ) learners. To comply with the objective, an experimental design was adopted. 55 pre - intermediate learners participated in the study. They were randomly divided into one control group, ...
Populus euphratica tree is a species naturally growing in riparian zones of rivers in arid and semiarid region where seasonal flooding and soil waterloging provides the conditions for this species. The aim of current study was to assess survival, growth characteristics and biomass allocation of Populus euphratica seedlings exposed to combined flooding- salinity stress at four levels including c...
