With an objective of evolving quantitatively and qualitatively superior bivoltine breeds/hybrids of silkworm Bombyx mori L. for tropical conditions, breeding work was initiated in Central Sericultural Research and Training Institute, Mysore during 1992 by utilizing two Japanese hybrids namely BNl8×BCS25 and Shunrei×Shogetsu along with Indian evolved breed, KA. The breed CSR12 which is characterized with sex-limited larval marking and white oval cocoons was evolved from the Japanese hybrid BNl8×BCS25 by crossing with KA, while the breed CSR6 which is characterized with normal marking (marked larvae) and white dumbbell cocoons was extracted from the Japanese commercial hybrid Shunrei×Shogetsu through continuous inbreeding coupled with selection. After fixation, these breeds along with other newly evolved breeds were subjected to hybrid study under optimum environmental conditions in the laboratory for expression of full potential of the genotypes. These hybrids were evaluated by Multiple Trait Evaluation Index (Mano et al., 1993). The hybrid CSR12×CSR6 was selected based multiple trait evaluation index value. The hybrid CSR12×CSR6 recorded survival of 96.0%, shell weight of 50.0 cg, shell ratio of 24.3%, raw silk percentage of 19.6, filament length of 1,216 m, boil off loss of 22.4% and renditta of 5.1. On the other hand, the control hybrid (KA×NB4D2) has recorded survival of 90.6%, shell weight of 42.1 cg, shell ratio of 20.4%, raw silk percentage of 15.9, filament length of 999 m, boil off loss of 24.8% and renditta of 6.3. The hybrid CSR12×CSR6 was authorized during 1997 by Central Silk Board, Government of India for commercial exploitation during favourable months based on national level race authorization test.

<P>ZnO nanotips structure fabrication was undertaken through controlled growth by chemical vapor deposition (CVD) method. Substrate position and deposition time role was investigated systematically by controlling the parameters such as temperature, flow rate, and growth pressure. The obtained result showed that ZnO nanorods undergo a sharp regrowth process with increase in ZnO vapor availability in the CVD reactor. The surface morphology and structural properties were investigated by using field-emission scanning electron microscopy and X-ray diffraction (XRD) techniques. The grown nanostructures were used for gas sensor fabrication to detect and to study the sensitivity effects of H-2 and CO.</P>

<P><B>Abstract</B></P> <P>An attempt to optimize Zn<SUB>2</SUB>SnO<SUB>4</SUB> (ZTO) thin film has been done by alternate thermal evaporation of ‘Sn’ and ‘Zn’ in the sequence Sn10/Zn15/Sn15/Zn15/Sn5 onto corning glass substrates and subsequent post oxidation process. The XRD patterns of as-deposited metallic thin films changed over from metallic to oxidized ZTO phase with cubic spinel structure along with ZnO phase. The film thickness and roughness increased apparently due to diffusion of oxygen into the metallic inter-layers. The binding energies estimated from the XPS data also indicated oxidation of the metallic multi-layers. Post-annealing of the film developed transparency in visible region to around 40%. The direct band gap of ZTO and ZnO were estimated to be 3.46 eV and 3.10 eV respectively. The annealed ZTO thin film was measured for electrical transport parameters by Hall Effect measurement. Raman spectrum observed at 668 cm<SUP>−1</SUP> is due to stretching vibration of short metal-oxide bonds in the MO<SUB>6</SUB> octahedron. The photoluminescence spectrum showed blue emission centered around 436 nm predominantly due to oxygen vacancies in addition to weak orange emission centered at 625 nm. Gas sensor using thin films of as-deposited and ZTO formed by post-annealing process showed significant sensing response for NO<SUB>2</SUB> gas. These results reveal that the ZTO thin film deposited by alternate thermal evaporation and subsequent post oxidation is worth exploring as transparent conducting electrode and also as a gas sensing material.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Metallic Sn and Zn were deposited by a newer alternate evaporation in Sn10/Zn15/Sn15/Zn15/Sn5 sequence. </LI> <LI> Upon annealing, metallic multi-layers gets intermixed and oxidized leading to Zn<SUB>2</SUB>SnO<SUB>4</SUB> phase. </LI> <LI> Transparency in visible region was around 40% with 3.46 eV direct band gap value. </LI> <LI> The PL emission has a broad asymmetric peak in blue region due to free-to-bound recombination. </LI> <LI> The annealed film has a response/recovery time of 51/107 s for 50 ppm of NO<SUB>2</SUB>. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

With a high death rate, oral cancer is a major worldwide health problem, particularly in low- and middle-income nations. Timely detection and diagnosis are crucial for efective prevention and treatment. To address this challenge, there is a growing need for automated detection systems to aid healthcare professionals. Regular dental examinations play a vital role in early detection. Transfer learning, which leverages knowledge from related domains, can enhance performance in target categories. This study presents a unique approach to the early detection and diagnosis of oral cancer that makes use of the exceptional sensory capabilities of the mouth. Deep neural networks, particularly those based on automated systems, are employed to identify intricate patterns associated with the disease. By combining various transfer learning approaches and conducting comparative analyses, an optimal learning rate is achieved. The categorization analysis of the reference results is presented in detail. Our preliminary fndings demonstrate that deep learning efectively addresses this challenging problem, with the Inception-V3 algorithm exhibiting superior accuracy compared to other algorithms.

An Approach to Develop a Compact Transmission Line Tower with Special 8-Legged Confi guration

Veerendra K. Shukla,M. Selvaraj,R. Ramesh Babu 한국강구조학회 2019 International Journal of Steel Structures Vol.19 No.1

For transmission of electricity from power generation plant to substations, many types of structures are being used. The main function of these structures is to support the power conductors and earth-wire. 4-legged steel lattice tower is one of these structures, which is widely used for this purpose. The main drawback of a 4-legged lattice tower is its larger base width, which occupy very large area. Nowadays, in many countries, adequate land is not available to consider such large land occupying towers. In these situations, using monopoles became common practice. But the monopoles are much costlier than the 4-legged lattice towers. To avoid the use of monopoles and to reduce the base width at the same time, in the present work, an approach has been adopted to use a special lattice type structure with eight legs. A 220 kV multi-circuit suspension tower with 0°–2° deviation has been considered for present study. The detail explanations, like, tower geometry, load calculations, analysis and design of the proposed structure has been covered in the paper. It has been observed that land requirement can be considerably minimized by use of the proposed 8-legged tower. The cost of the 8-legged tower is slightly more than a 4-legged tower but much lesser than that of monopoles as the total weight of steel required is very less as compared to monopole. The results obtained from the study of the proposed tower have been compared with 4-legged tower and monopole. This paper discusses the feasibility of using the transmission line tower with 8-legs. The paper also discusses a comparative study of cost, right of way, height and base width of 4-legged tower, monopole and proposed 8-legged tower .
