No full textThe book provides a comprehensive overview of antennas for 5G technology, such as MIMO, multiband antennas, Magneto-Electric Dipole Antenna and PIFA Antenna for 5G networks, phased array antennas for 5G access, beam-forming and beam-steering issues, 5G antennas for specific applications (smartphone, cognitive radio) and advance antenna concept and materials for 5G. The book also covers ooptimizations methods for passive and active devices in mm-Wave 5G networks. It explores topics which influence the design and characterization of antennas such as data rates, high isolation, pattern and spatial diversity, making 5G antennas more suitable for a multipath environment. The book represents a learning tool for researchers in the field, and enables engineers, designers and manufacturers to identify key design challenges of antennas for 5G networks, and characterize novel antennas for 5G networks

Comparison of the clinical applicability of Miller's classification system to Kumar and Masamatti's classification system of gingival recession
No full textBackground: The aims of the present study were to (i) Find the percentage of recession cases that could be classified by application of Miller's and/or Kumar and Masamatti's classification of gingival recession, and (ii) compare the percentage of clinical applicability of Miller's criteria and Kumar and Masamatti's criteria to the total recessions present. Materials and Methods: A total of 104 patients (1089 recession cases) were included in the study wherein they were classified using both Miller's and Kumar and Masamatti's classification systems of gingival recession. Percentage comparison of the application of both classification systems was done. Results: Data analysis showed that though all the cases of the recession were classified by Kumar and Masamatti's classification, only 34.61% cases were classified by Miller's classification. 19.10% cases were completely (having only labial/buccal recession) classified. In 15.51% (out of 34.61%) cases, only buccal recession was classified according to Miller's criteria and included in this category, although these cases had both buccal and lingual/palatal recessions. Furthermore, 29.75% cases of recession with interdental loss and marginal tissue loss coronal to mucogingival junction (MGJ) remained uncategorized by Miller's classification; categorization of palatal/lingual recession was possible with Kumar and Masamatti's classification. Conclusion: The elaborative evaluation of both buccal and palatal/lingual recession by the Kumar and Masamatti's classification system can be used to overcome the limitations of Miller's classification system, especially the cases with interdental loss and having marginal tissue loss coronal to MGJ
Global Lentil Production: Constraints and Strategies
No full textLentil (Lens culinaris ssp. culinaris) is an important food legume crop with global
production of 3.59 million tonnes. The crop suffers substantial yield losses from
various biotic and abiotic stresses. Past efforts have been directed towards
developing improved varieties with resistance to one or the other biotic stress,
improving the seed size and shortening the crop duration to fit lentil in various
cropping systems. In the past one decade, production and productivity of lentil
have stagnated in the traditional base of South Asia. In order to break the current
yield plateau in lentil, there is a need to develop extra short duration varieties for
rice-based systems for South Asia, drought and heat tolerant varieties with multiple
disease resistance for all the regions, and herbicide-tolerant and machine
harvestable varieties for West Asia and North Africa (WANA) region. This requires
a comprehensive research for developing strategy involving both the conventional
and genomics tool
Culture selected somaclonal variants showing low-ODAP and high protein content in nineteen grass pea (Lathyrus sativus L.) genotypes
No full textTo develop low-ODAP grass pea genotypes with high protein content, in vitro tissue culture techniques were used for inducing somaclonal variation through internode explants that was cultured on B5 medium containing 2 mg L−l α-naphthaleneacetic acid and 1 mg L− l 6-benzylaminopurine of 19 grass pea genotypes. The selected somaclones ( R3 and R4 generations) were evaluated for variation in ODAP, protein, and quantitative agronomic traits. The results showed statistically significant (P < 0.001) genotypic differences for ODAP %, Protein %, 100-seed weight (HSW) and pod width (PODW) in the R4
somaclones under field conditions. The somaclones showed broad-sense heritability estimate of 0.14 ± 0.064 for ODAP%, 0.87 ± 0.015 for protein, 0.78 ± 0.025 for HSW and 0.13 ± 0.062 for PODW. Among the 270 somaclones, Sel462-5 was significantly superior to the parent and other somaclones in terms of ODAP content (0.13%), protein content (28.47%) and pod width (1.43 cm). The correlation coefficients between parents and somaclones for pod width with 100-seed weight, ODAP-clones and protein-clones were positive and significant. The superiority of somaclones for ODAP, protein, 100-seed
weight and pod width in R4 generation opened the possibility for grass pea improvement through somaclonal variation
In vitro New Approaches for Shortening of Generation Cycles and Faster Breeding of Grass pea (Lathyrus sativus L.)
No full textFlowering is a complex process regulated by a combination of genetic and environmental factors. Grass pea (Lathyrus sativus L.) grows as long day plant under natural conditions with single breeding cycle per annum. There is need to develop strategies by accelerating breeding activities making it possible to grow more than one generation per annum that is impossible under natural conditions. In line with this objective, this mopho physiological study searched for alternatives by treating explants in vitro with 6-benzylaminopurine (BAP) and α-naphthaleneacetic acid (NAA) to induce earlier flowering with aim of leading to accelerated breeding. Nodal junctions bearing about 0.5 cm portion of internodes on both sides were used as explants. The Murashige and Skoog (MS) medium supplemented with 2 mg L-1 BAP and 1 mg L-1 NAA was found optimum for production of multiple shoots. The regenerated plantlets induced floral buds and flowers within two weeks of culture on MS medium supplemented with 0.1 - 0.5 mg L-1 BAP. Flowering was observed on the regenerated plantlets with an average number of 4.30± 0.32 flowers per plantlet that continued during acclimatization. In vitro rooting was observed (83.43±2.92%) in the presence of MS medium containing 0.10 mg L-1 indole butyric acid (IBA). The regenerated plants were acclimatized in the greenhouse, where they set seeds. It was concluded that it was possible to obtain 4.3 generations per annum. The results are very encouraging and could save time significantly for accelerated breeding of grass pea
