Abstract: 

In bread wheat (Triticum aestivum L. ), crop height is an important determinant of agronomic performance. To map QTLs with ADDITIVE effects and ADDITIVE×ADDITIVE epistatic interactions, 148 recombinant inbred lines and their parents, (‘ YecoraRojo’ and Iranian landrace (No. #49)) were evaluated under normal and water deficit conditions. The experiments were carried out on research farms of Mahabad University and Miyandoab Agricultural Research Center in 2014-2015. The experimental design was an alpha lattice design with two replications. Quantitative trait loci (QTL) for the studied traits were carried out for ADDITIVE effects and ADDITIVE×ADDITIVE epistatic interactions using the QTL Network 2. 0 software based on the mixed-linear model. A number of 177 microsatellite and 51 retrotransposon markers were used to construct the linkage map. In the present study stem length, plant weight, peduncle length, and peduncle weight were measured. Results showed that under both normal and water deficit conditions, both positive and negative transgressive segregations were significant, also the highest and lowest broad and narrow sense heritability were estimated for stem length (73. 69 and 36. 74 percent) and peduncle length (40. 51 and 20. 25 percent), respectably. The results showed that under the normal condition, seven QTLs (R2 A=5 to 11%), and eight ADDITIVE×ADDITIVE epistatic interactions (R2 AA=1. 66 to 10. 92%) were significant. Under the water deficit condition seven QTLs (R2 A=4. 27 to 9%), and five ADDITIVE×ADDITIVE epistatic interactions (R2 AA=3. 8 to 14. 58%) were significant. Five QTLs from the 14 QTLs identified in this study were located in chromosome 5A, indicating the importance of this chromosome in controlling the plant architecture characteristics and possibly using it for marker-assisted selection and genetic engineering.

Abstract: 

To map quantitative trait loci (QTL) for harvest index, 148 recombinant inbred lines and their parents, Yecora Rojo and an Iranian landrace line (No. 49), were evaluated under normal and terminal water deficit stress conditions in the research stations of Mahabad University and Miyandoab Agricultural Research Center, Iran, during 2014 and 2015. The experiment was carried out as design alpha lattice design with two replications. A linkage map of 51 retrotransposon and 177 microsatellite markers was used in this investigation. Quantitative trait loci (QTL) for ADDITIVE effects and ADDITIVE × ADDITIVE interactions were determined by QTL Network 2. 0 software using CIM and mixed-linear methods. QTL analysis revealed that under normal condition, six QTLs (R 2 A= 0. 04 to 12. 0%), two QTL × environment (E) interactions (R 2 AE= 6. 28%), five ADDITIVE × ADDITIVE epistatic effects (R 2 AA= 0. 7 to 8. 68%) and 12 ADDITIVE × ADDITIVE × E (R 2 AAE= 3. 76 to 11. 4%) were significant. Under water deficit stress conditions, two QTLs (R 2 A= 5. 0 to 7. 0%), two ADDITIVE × ADDITIVE interactions (R 2 AA= 3. 72 to 5. 48%) and seven ADDITIVE × ADDITIVE × E interactions (R 2 AAE= 8. 04 to 9. 58) were identified. Among the eight QTLs identified, three QTLs were located on chromosome 2D, suggesting the importance of this chromosome in controlling harvest index, which may be used for marker assisted selection in breeding programs.

Abstract: 

The Sensitivity of Quantitative electroencephalogram (Brain MAPPING) was Compared with Transient ischemic Attack (TIA) and computerized tomography (C.T. Scan) Finding. Twenty Patients were tested with Quantitative EEG (Brain MAPPING) within 24h from the onset of neurological symptoms where as CT Scan was performed within 24h from the onset of attack. EEG was recorded from 16 electrodes placed upon the Scale to the international 10-20 system. Spectral analysis was carried out for each channel. Absolute and Relative power were calculated for Delta - Theta -Alpha and Beta frequency bands and such data were successively represented in color coded maps. The results indicated that EEG MAPPING showed focal abnormality in delta band in 17 of 20 cases.

Abstract: 

Let X and Y be normed linear spaces. A MAPPING  T : X®Y is called preserving the distance r if for all x, y of X with ||x – y|| = r then ||T(x) − T(y)|| = r. In this paper, we provide an overall account of the development of the Aleksandrov problem, the Aleksandrov–Rassias problem for MAPPINGs which preserve distances and details for the Hyers–Ulam–Rassias stability problem.

Abstract: 

Introduction: Maps can create a deeper insight of our surrounding environment. The map can also be used in curriculum for its reforming, and developing and ultimately improving teaching-learning process. This systematic review aimed to identify applications and benefits of curriculum MAPPING.Methods: Seven search engine and websites were searched using the keywords including curriculum MAPPING, curriculum map (s), medical, curriculum development and planning.1100 article was found and 179 articles were enrolled in the study. Then the relevant article (i.e.36 articles) were selected and analyzed.Results: 112 advantage and 111 applications were found in reviewed articles.32 advantage and 29 applications were listed after removing repetitive cases and merging some cases. The most common mentioned advantage was developing a participation culture (students and teachers participation in curriculum). Most applications of these maps were curriculum monitoring and evaluation from different perspective regarding to the required competencies for students.Conclusion: Various users including curriculum planners, administrators, professors and students use curriculum MAPPING according to their needs. Regarding the benefits of curriculum MAPPING and its various applications in the educational system, it is suggested that teachers and administrators in each department, design a curriculum map in a project. In this regard, computer programmers can increase accuracy and speed in the project.

Abstract: 

The present paper investigated the effectiveness of concept MAPPING as a learning strategy on EFL students’ self-regulation (metacognitive self-regulation, time and study environment, effort regulation, peer learning, and help seeking). Sixty university students participated in the study. They were randomly assigned to control and experimental groups, each including thirty students. They were at the intermediate level of English proficiency and studying English either Translation or Literature. Their language proficiency was determined by the Michigan Test of English Language Proficiency (MTELP) (Corrigan, 1979). The instrument to collect data on the students’ selfregulation was the Motivated Strategies for Learning Questionnaire (MSLQ) (Printrich et al., 1991). The findings revealed that students gained higher self-regulation in writing tasks as the result of the explicit instruction of the concept MAPPING strategy. The findings have implications for pedagogy as well as for research.
