A numerically efficient technique for the analysis of slots in multilayer media

Cataloged from PDF version of article.A numerically efficient technique for the analysis of slot geometries in multilayer media is presented using closed-form Green's functions in spatial domain in conjunction with the method of moments (MoM). The slot is represented by an equivalent magnetic-current distribution, which is then used to determine the total power crossing through the slot and the input impedance. In order to calculate power and current distribution, spatial domain closed form Green's functions are expanded as power series of the radial distance rho, which makes the analytical evaluation of the spatial domain integrals possible, saving a considerable amount of computation time

Co 15002: A potential fifth generation inbred derivative developed through inbreeding followed by hybridization and selection for sugarcane improvement

Among 129 clones evaluated along with standard varieties CoC 671 and Co 86032 in Pre-zonal varietal trial (PZVT) during 2014-15, the clone PZVT 13-175 recorded the highest cane yield of 143.52 t/ha which was significantly superior to both the standards. Consequently the clone was given Co status i.e. Co 15002 and was included in Initial Varietal Trial of All India Co-ordinated research Project on Sugarcane in Peninsular Zone along with 25 other test entries and four standards at 15 test locations during the year 2018-19. Co 15002 registered significantly higher sucrose content (19.43%) than the commercially released sugarcane variety CoSnk 05103 (18.96 %) and on par with the ruling variety Co 86032 (19.63 %) at 10th month crop maturity. Cane yield of Co 15002 (96.27 t/ha) was found to be on par with the recently released CoSnk 05103 (97.23 t/ha) and CoC 671 (99.30 t/ha). Co 15002 was screened for red rot, smut and yellow leaf diseases under natural and artificially inoculated conditions at Coimbatore, Pune, Kolhapur and Navsari. Under natural conditions, smut and yellow leaf diseases were not observed. Co 15002 was resistant or moderately resistant to red rot by both plug and nodal methods in all the test locations. In artificial inoculated conditions, Co 15002 showed resistance to moderately resistant reaction to smut. It recorded 20 % flowering intensity and low pollen fertility of 30 % with peak flowering during the first fortnight of November and can be used as a pistil parent in hybridization programmes

Indoleamine 2,3-dioxygenase 1 activation in mature cDC1 promotes tolerogenic education of inflammatory cDC2 via metabolic communication

Conventional dendritic cells (cDCs), cDC1 and cDC2, act both to initiate immunity and maintain self-tolerance. The tryptophan metabolic enzyme indoleamine 2,3-dioxygenase 1 (IDO1) is used by cDCs in maintaining tolerance, but its role in different subsets remains unclear. At homeostasis, only mature CCR

Altered compensatory cytokine signaling underlies the discrepancy between Flt3–/– and Flt3l–/– mice

The receptor Flt3 and its ligand Flt3L are both critical for dendritic cell (DC) development, but DC deficiency is more severe i

Sensitivity of seedling growth, fertility and yield contributing traits in rice (Oryza sativa L.) to electron beam and Ethyl Methane Sulphonate

Rice (Oryza sativa L.) plays a pivotal role in global food security, necessitating continuous efforts to enhance yield potential and grain quality. Mutation breeding, employing physical (electron beam) and chemical (ethyl methane sulphonate, EMS) mutagens, offers a promising avenue for creating genetic variability. This study assessed the sensitivity of rice variety ASD 16 and landrace Norungan to varying doses of electron beam (100 Gy to 500 Gy) and EMS (30 mM to 70 mM). The genotypes exhibited dose-dependent responses in germination, seedling survival, shoot and root length, seedling height, pollen fertility and spikelet fertility. The LD50 values for electron beam under in vivo and in vitro conditions were 314.24 Gy and 348.21 Gy respectively for ASD 16 and 445.07 Gy and 461.88 Gy for Norungan whereas for EMS, the LD50 values for ASD 16 were 49.17 mM and 55.37 mM; 53.53 mM and 65.12 mM for Norungan under in vivo and in vitro conditions based on probit analysis. ASD 16 showed a GR50 value of 309.02 Gy for the electron beam and 51.60 mM for EMS while Norungan exhibited a GR50 value of 538.79 Gy for electron beam and 98.71 mM for EMS. The variety, ASD 16 demonstrated higher sensitivity, proved by greater growth reduction percentages and lower lethal dose 50 (LD50) values compared to landrace Norungan. Electron beam treatments induce significant reductions in various growth traits, underlining the potential deleterious effects at higher doses. EMS, as a chemical mutagen, also impacted germination and growth characteristics. Both mutagens affected pollen and spikelet fertility with notable influence on yield contributing traits. This finding emphasizes the significance of precise dosage selection in mutation breeding to induce desirable traits and maintaining complete plant viability and productivity. Understanding genotype-specific responses is crucial for successful mutation breeding programmes. Overall, this study offers valuable insights into the application of electron beam and EMS mutagenesis in rice, contributing to the optimization of mutagenic protocols for crop improvement
