Silymarin is a hepatoprotective agent, having poor water solubility and oral absorption of about 23 - 47%, leading to low bioavailability the drug. The aim present study improve dissolution rate in turn activity drug, by formulating its inclusion complex with beta (β)-cyclodextrin, using different methods. phase analysis indicates formation 1:1 molar drug cyclodextrin. Apparent stability constant for (K(c)) was 722 K(-1) β-cyclodextrin complex. complexes were prepared four methods, namely,...
In the context of electricity shortage and an attempt to save environment, introduction energy efficient motors in different fields application has become a necessity. This paves way for fusing conventional machine design procedures with optimization techniques. Unfortunately, mathematics electrical involves calculations highly nonlinear equation sets, hence analytical techniques do not fit well. this study, efficiency-optimized squirrel cage induction motor is considered, where genetic...
Diagnosing brain tumors using magnetic resonance imaging (MRI) presents significant challenges due to the complexities of segmentation and variability in tumor characteristics. To address limitations inherent traditional methods, this research employs an advanced deep learning approach, integrating ResNet50 for feature extraction Generative Adversarial Networks (GANs) data augmentation. A comprehensive evaluation ten transfer algorithms, including GoogLeNet VGG-16, was conducted...
This article presents a new collaborative control method based on expert decision, proposed for the combined system of an ac grid with low THD thyristorized static var compensator (SVC), interconnected to dc microgrid through distribution (D-STATCOM) that also works as bidirectional power converter. The combination large rating SVC and D-STATCOM functions hybrid grid. In mode operation, mitigates voltage fluctuations compensates initial demands, while caters base requirements. has been used...
A hybrid compensator with a new coordinated control is proposed for mitigating power quality aspects and integration of renewable in an unbalanced three-phase four-wire distribution system. The comprises thyristor switched capacitor (TSC) banks, delta connected controlled reactor (TCR), 3rd 5th harmonic tuned passive LC filter & low rating D-STATCOM. TSC-TCR operates asymmetrically the base var compensation also eliminates negative sequence current during loading at point common coupling...
The present investigation were carried out with a view to find the incremental cost benefit ratio of different insecticides and bio-pesticides against brinjal shoot fruit borer (Leucinodes orbonalis Guenee) in Kharif season at Student’s Instructional Farm (SIF), Chandra Shekhar Azad University Agriculture Technology, Kanpur, Uttar Pradesh, during 2022 2023. study aimed evaluate efficacy cost-effectiveness insecticidal bio-pesticidal treatments for managing L. enhancing yield. Based on...
The present study investigates the biology of brinjal shoot and fruit borer (Leucinodes orbonalis Gue.) under normal room temperature conditions during 2022 2023. Key developmental parameters, including egg hatching, larval pupal duration, fecundity total life span, were recorded. Egg hatching percentage remained consistent at 54%, with an incubation period 3-5 days (3.6 ± 0.40 days). was 12.4 0.60 in 13.4 0.68 2023, while stable 9 0.45 days. varied from 23-30 (26.4 1.21 days) to 22-26 (23.8...
Ultrasonic force microscopy (UFM) was introduced to probe nanoscale mechanical properties of stiff materials. This achieved by vibrating the sample far above first resonance probing atomic microscope cantilever where becomes dynamically rigid. By operating UFM at different set values, it is possible directly measure absolute values tip-surface contact stiffness. From this an evaluation surface elastic can be carried out assuming a suitable solid-solid model. In paper we present curves...
This study presents a generalised online switching scheme for space vector pulse-width modulation (SVPWM)-based multilevel inverter of any voltage level. The proposed SVPWM algorithm implements three-(similar to five) and seven-segment using the three most desired states one suitable redundant state each triangle. In addition, novel three-segment has been proposed, which eliminates extra commutations hence minimises frequency devices while reducing harmonics. expressions is implemented...
Sustainable irrigation method is now essential for adaptation and adoption in the areas where water resources are limited. Therefore, a field experiment was conducted to test performance of alternate wetting drying furrow (AWDFI) on crop growth, yield, use efficiency (WUE), fruit quality profitability analysis tomato. The laid out randomized complete block design with six treatments replicated thrice during dry seasons 2013–2014 2014–2015. Irrigation applied through three ways furrow: AWDFI,...
Thermal stability behavior of 1H, 1H,2H,2H-perfluorooctyl trichlorosilane self-assembled on aluminum substrates is characterized using a grazing-angle Fourier transform infrared spectrometer, transform-Raman spectroscopy, and contact angle measurements. The monolayer (SAM) heated quasi-statically from room temperature to above 633 K with heating rate 1 K/s. Variations in peak frequencies, integrated areas intensities symmetric antisymmetric CF2 stretches, the relative tilt SAM are reported....
