Quasistatic Resonators Based Triple-Mode Notched Microstrip Bandpass Filter

This article discusses new approach for design and development of triple-mode notched microstrip bandpass filter based on quasistatic resonators(QR). The proposed approach is composed of two Quasistatic resonant elements; Horizontal plane Split ring resonator (HP-SRR), Vertical plane split ring resonator (VP-SRR) and a single asymmetric step impedance resonator (A-SIR) with parallel coupled feed structure. An additional attenuation pole realized by VP-SRR in desired passband, tunes the dual-mode response to triple mode and enhances the 3dB bandwidth without changing the dimensions of basic the filter cell. The HP-SRR realizes a notch at WiMAX band (IEEE 802.11a lower band) in the desired passband. Further by changing the impedance of VP-SRR and HP-SRR both the location of additional attenuation pole frequency and notch band can be controlled. The proposed approach results in compact, notched wideband, filter design

Influence of biostimulants on growth and productivity of foxtail millet (Setaria italica L.) genotypes

A field experiment was carried out at AHRS, Bavikere, Karnataka during late kharif season of 2021to find out the “Influence of biostimulants on growth and productivity of foxtail millet (Setaria italica L.) genotypes’’. The field trial was laid out in split plot design with 12 treatment combinations. The study involves three genotypes in the main plot viz., SiA-3156 (G1), HMT-100-1 (G2) and DHFt-109-3 (G3). Foliar application of biostimulants in sub plots viz., 0.1 % humic acid (F1), 3 % panchagavya (F2), 0.1 % humic acid and 3 %panchagavya (F3) at 30 and 60 days after sowing (DAS) and recommended dose of fertilizer (RDF) as control (F4). Genotypes and Foliar application of biostimulants exhibited significant variation in growth and yield components of foxtail millet. Among the different genotypes, HMT-100-1 recorded significantly higher plant height (142.00 cm), number of tillers per meter (81.87) and leaf area (18.40 dm2/plant) at harvest and also yield components like panicle length (16.60 cm), grain weight per panicle (4.02 g) and grain yield (1701.0 kg/ha) compared to DHFt-109-3 and SiA -3156. In biostimulants, Foliar application of 0.1 % humic acid and 3 % panchagavya recorded significantly higher plant height (142.32 cm), number of tillers per metre (83.75) and leaf area (18.51 dm2/plant) at harvest and also yield components like panicle length (16.99 cm), grain weight per panicle (4.33 g) and grain yield (1781.2 kg/ha). While, they were found to be at their lowest with application of RDF alone. Interaction between genotypes and biostimulants was also found to be significant in which combination of HMT-100-1 with foliar application of 0.1 % humic acid and 3 %panchagavya recorded significantly higher growth and yield compared to other treatment combinations

Growth of Indian Research in Science and Technology: A Scientometric Analysis

This article carried out a Scientometric analysis of research publications published in various science and technology journals from 2011 to 2020 from India. Required data was retrieved from WoS database during the study period it provides information about the science and technology related publications from India. Especially, scientific data on the top research areas and distribution of publication collaborations in different dimensions of geography, authors, funding agencies, subjects and others. It examines the year wise publications, annual distribution of publications, most prolific authors, authors and organisations productivity, etc. Analysis found that, highest research publications are published in the year 2019 with 13.16%, followed by 2020 with 12.98% and in the year 2018 with 11.51%. Research articles are published 81.51% compared to any other type of publications from all over India. 88% of the research fund is provided by the Government of India, and remaining are from the western world among the top ten funding agencies. Out of top ten journals, seven (76%) of them are originated from India, two are from United Kingdom and one journal is from United States of America. During the study period, it is observed that, a mean relative growth rate is 0.26. Notably, the doubling time for the publications has decreased from 0.35 in the first five years to 0.17 in the last five years. Publications are raised on an average of 4.72% per year. On the whole, 208 countries collaborators contributed to these publications

In vivo comparative evaluation of mineral trioxide aggregate and formocresol pulpotomy in primary molars: A 60-month follow-up study

Introduction: Pulpotomy is a regular procedure in the management of inflamed primary teeth. Diverse materials have been reviewed for the pulpotomy, some of them being formocresol, glutaraldehyde, ferric sulfate, and mineral trioxide aggregate (MTA). Aims: The aim was to evaluate and compare clinically and radiographically the effects of MTA as a pulp dressing after coronal pulp amputation (pulpotomy) in primary molars. Settings and Design: Sixty primary molars of thirty healthy children using split mouth design aged between 4 and 6 years were treated by pulpotomy technique. Subjects and Methods: Sixty primary mandibular molars of thirty healthy children aged between 4 and 6 years were treated by pulpotomy technique. The teeth on the right side were assigned to MTA (Group A) and the left side for the formocresol (Group B). The children were then examined clinically and radiographically every 6 months. Statistical analysis used: Chi-square test using the SPSS version 19.0 was used to compare between the two groups. Results: Results showed that both MTA and formocresol have the same outcome on the primary molars, with Chi-square value being 1.1483 (P ≥ 0.05). None of the teeth in any children in the study showed any clinical pathology. Conclusion: The principle conclusions of this study are that there are no significant differences in MTA and formocresol. The success rate of MTA and formocresol pulpotomy can be considered comparable till this therapy influences the development and growth of the permanent teeth

Effect of Crop Specific Blended Fertilizers on Growth and Yield of Maize (Zea mays L.)

A Field experiment was conducted during Rabi 2022-23 at Agricultural and Horticultural Research Station, Kathalagere, KSNUAHS, Shivamogga, to study the effect of crop specific blended fertilizers on the growth and yield of maize. The experiment was laid out in Randomized Complete Block Design with ten treatments replicated thrice. Nutrient composition of blended fertilizer used for basal application was 16:18:11:4:1 N:P2O5:K2O:S:Zn and for top dress was 27: 0:13 N:P2O5:K2O. The treatments T1, T2, T3 consisted of application of basal blended fertilizer @ 312.5, 412.5 and 515 kg ha-1, respectively and top dress blended fertilizer @ 237.5, 312.5 and 390 kg ha-1, respectively. Basal blended fertilizer @ 412.5 kg ha-1 + top dress of urea at 30 and 45 DAS (T4), Package of practice (PoP) through straight fertilizer (T5), PoP through complex fertilizer (T6), recommended dose through Urea, DAP, MOP and ZnSO4  + top dress of nano urea @ 0.4% at 30 and 45 DAS (T7), physical blending of Urea, SSP, MOP and ZnSO4 (16:18:11:4:1 N:P:K:S:Zn) for basal and Urea and MOP (27:0:13 N:P:K) for top dress (T8), farmers' practice (T9) and absolute control (T10). Among all treatments, the application of basal blended fertilizer @ 515 kg ha-1 + Top dress of blended fertilizer @ 390 kg ha-1 recorded the maximum plant height (222.4 cm), number of leaves (10.3 plant-1), total dry matter accumulation (285.86 g plant-1), cob length (21.31 cm), cob girth (18.31 cm), number of kernels per cob (516.57) and test weight (24.22 g) at harvest as compared to PoP through straight and complex fertilizer and absolute control. The same treatment recorded significantly higher kernel and straw yield (69.51 and 89.36 q ha-1, respectively) in comparison to other treatments but it was on par with T2, T5 and T6. The treatment T3 recorded 27.8 % higher yield compared to T9.  In study area the application of basal blended fertilizer @ 515 kg ha-1 + Top dress of blended fertilizer @ 390 kg ha-1 is recommended to achieve higher growth and yield of maize
