Over the last two years, research conducted at the NCAUR in Peoria, IL, in conjunction with The Ohio State University (Khan et al, 1998a; Khan et al., 1998b; Khan et al., 1999a; Khan et al., 1999b; Schisler et al., 1999a; Schisler et al., 1999b), has culminated in the isolation, screening and identification of several putative biological control agents for suppression of FHB. This update provid...
a frame semantic approach to the study of translating cultural scripts in salingers franny and zooey
the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...
Soil nitrogen cycling microbial communities and functional gene α−diversity indicate soil ecological functions potentials. Crop rotation plans affect fractions these indicators. We sequenced samples from four crop (fallow, winter wheat monoculture, pea-winter wheat-winter wheat-millet rotation, corn-wheat-wheat-millet rotation) in a long-term field experiment. examined how changed with regulate...
in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
Enhanced N2O Emissions from Winter Wheat Field Induced by Winter Irrigation in the North China Plain
Winter irrigation is important for wheat in meeting crop water requirements spring, but it alters soil moisture dynamics and affects N2O production emission. To assess the effects of winter on emissions a field, an situ experiment was conducted from 1 October 2019 to March 2020 with one control treatment (CK) five levels quantities (irrigated 60%, 70%, 80%, 90%, 100% holding capacity, namely WH...
in this study reference as one of the five cohesive devices in the achievement of textuality in english and persian narrative/descripitive written texts is focused on and analysed . to do so , the theoretical framework elaborated by halliday and hasan (1976) and its version adapted by the writer to match the sub-types of reference in farsi are applied to the analysis of reference in english and...
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Wheat growth in response to soil water deficit play an important role in yield stability. A field experiment was conducted for winter wheat (Triticum aestivum L.) during the period of 2002–2005 to evaluate the effects of limited irrigation on winter wheat growth. 80%, 70%, 60%, 50% and 40% of field capacity was applied at different stages of crop growth. Photosynthetic characteristics of winter...
