Stripe rust, caused by Puccinia striiformis West. f.sp. tritici, is one of the most damaging diseases of wheat worldwide. Forty genes for stripe rust resistance have been catalogued so far, but the majority of them are not effective against emerging pathotypes. Triticum monococcum and T. boeoticum have excellent levels of resistance to rusts, but so far, no stripe rust resistance gene has been identified or transferred from these species. A set of 121 RILs generated from a cross involving T. monococcum (acc. pau14087) and T. boeoticum (acc. pau5088) was screened for 3 years against a mixture of pathotypes under field conditions. The parental accessions were susceptible to all the prevalent pathotypes at the seedling stage, but resistant at the adult plant stage. Genetic analysis of the RIL population revealed the presence of two genes for stripe rust resistance, with one gene each being contributed by each of the parental lines. A linkage map with 169 SSR and RFLP loci generated from a set of 93 RILs was used for mapping these resistance genes. Based on phenotypic data for 3 years and the pooled data, two QTLs, one each in T. monococcum acc. pau14087 and T. boeoticum acc. pau5088, were detected for resistance in the RIL population. The QTL in T. monococcum mapped on chromosome 2A in a 3.6 cM interval between Xwmc407 and Xwmc170, whereas the QTL from T. boeoticum mapped on 5A in 8.9 cM interval between Xbarc151 and Xcfd12 and these were designated as QYrtm.pau-2A and QYrtb.pau-5A, respectively. Based on field data for 3 years, their R2 values were 14 and 24%, respectively. T. monococcum acc. pau14087 and three resistant RILs were crossed to hexaploid wheat cvs WL711 and PBW343, using T. durum as a bridging species with the objective of transferring these genes into hexaploid wheat. The B genome of T. durum suppressed resistance in the F1 plants, but with subsequent backcrossing one resistance gene could be transferred from one of the RILs to the hexaploid wheat background. This gene was derived from T. boeoticum acc. pau5088 as indicated by co-introgression of T. boeoticum sequences linked to stripe rust resistance QTL, QYrtb.pau-5A. Homozygous resistant progenies with 40-42 chromosomes have been identified.
Purpose This paper aims to revisit the role of perceived risk in online banking, using an alternative view on trust as a moderator on the relationship between perceived risk and behavioral intention (BI). With this aim, the conceptual model was proposed to examine the impact of perceived risk on BI directly and indirectly via unified theory of acceptance and use of technology 2 along with its interactionist relationship with trust. Design/methodology/approach Structural equation modeling technique is used to analyze data collected from 677 bank customers via personal contact using a self-administered questionnaire. Findings The results indicate that perceived risk as a multi-dimensional construct has a direct and indirect impact on BI via performance expectancy, social influence, hedonic motivation and price value. Moreover, it was found that trust moderates the relationship between perceived risk and BI. Practical implications This study suggests that banks should create a trust-building mechanism in the online banking environment and develop certain risk management strategies such as providing detailed and thorough information, money-back guarantee and reassurance services to enhance confidence among the customers to use such services. The banks should also devote valuable efforts in designing website interface with improved security features to facilitate usability and reliability of online banking services. Originality/value The present study makes an important contribution to the existing literature on e-commerce, especially in the field of online banking, by proposing an interactionist model between perceived risk and trust. The proposed model has never been examined in the relevant literature and could be used to provide a solid theoretical foundation in the context of online banking adoption.
Developmental milestones in children or infants are a certain set of skills or age-specific tasks. Missed or delayed milestones in infancy can be symptoms of serious medical conditions. If parents understand their children’s development, they can tailor their expectations and provide stimulation. This study was conducted to assess the level of knowledge regarding the development milestones of infants among mothers. A descriptive study was conducted on 100 mothers of neonates visiting pediatric OPD and gynecological unit (Postnatal Ward).A convenience sampling technique was used to collect data. More than half of mother’s i.e. 60% had an average level of knowledge, 22% of mothers had a poor level of knowledge and 18% of mothers had a good level of knowledge. Mothers had the highest (75.25%) mean knowledge percentage in general information followed by 53.33%, in developmental delay and least (37.50%) mean knowledge percentage in language development. The overall mean knowledge score is 10.240±2.40 and there is no association (p>0.05) between the knowledge level of mothers with selected demographic variables. It is concluded that the majority of the mothers of neonates had average knowledge regarding developmental milestones.
The focus of this work is to consolidate a review of accomplished research in the field of optical code division multiple accesses (OCDMA), to outline the state-of-the-art comparison, and to recognize the prominent trends as well as limitations. Code division multiple access (CDMA) has prospered as a vital solution for numerous applications such as cellular mobile communication-based wireless network technology and wired/wireless local area networks that include areas of unlicensed industry, medicine, and science. Due to the commercial utilization of the various advantages of CDMA, it has raised the matter of whether optical technology reliant communications provide the noteworthy advantages to optical networks as well as what are the technologies that facilitate optical chip-based (code division) networks. Aforementioned matter has been addressed in the context of the incorporation of OCDMA in the systems through several experiments of laboratory-based test-bed investigations, field trials, and simulation analysis of multiple users in the recent research works. The performance of OCDMA has an edge over wavelength division multiplexing and offers an unmatched capacity that is seen through simulations. To cater the explosive expansions in internet application, different spectral amplitude codes have been proposed till now. We present a review of the different spectral amplitude codes based on the reported works in spectral amplitude code OCDMA systems. For the purpose of state-of-the-art comparison, parameters considered are data speeds, advanced modulation formats, bit error rate, extinction ratio, decision algorithms, photonic efficiencies of photodetectors, frequency bands, signal-to-noise ratio, forward error correction, photodetector noises, etc., and simulations are carried out in similar input environments. We explore the advantages/limitations of the spectral amplitude codes, recent progress in the technology, practical works on spectral amplitude coding (SAC) throughout the world, encryption-decryption techniques, all-optical methods, literature comparison, future scope, and applications of the SAC-OCDMA codes.
