Harmonics Reduction of a Single Phase Half Bridge Inverter
This paper displays a way to deal with minimize the sounds contained in the output of a solitary stage half scaffold inverter. With a perspective to decreasing Harmonic a LC low pass filter is utilized which hinders the music and irrefutably passes verging on sinusoidal yield at the yield terminal. A representation of Fourier Transform has been given in this paper with a specific end goal to see both the basic and music part decisively. It has been found from recreation that the Total Harmonic Distortion (THD) previously, then after the fact the application is 44.999% and 0.0183% separately. That is the reason, this LC low pass channel is very compelling to diminish THD of a 1-stage half extension inverter
Interaction of Fusarium oxysporum f. sp. ciceri and Meloidogyne javanica on Cicer arietinum
Interaction of Meloidogyne javanica and Fusarium oxysporum f. sp. cice~q was studied on Fusarium
wilt-susceptible (JG 62 and K 850) and resistant (JG 74 and Avrodhi) chickpea cultivars. In
greenhouse experiments, inoculation of M. javanicajuveniles prior to F. oxysporum f. sp. ciceri caused
greater wilt incidence in susceptible culfivars and induced vascular discoloration in roots of resistant
cultivars. Nematode reproduction was greatest (P = 0.05) at 25 °C. Number of galls and percentage of
root area galled increased when the temperature was increased from 15 °C to 25 °C. Wilt incidence was
greater at 20 °C than at 25 °C. Chlorosis of leaves and vascular discoloration of plants did not occur at
15 °C. The nematode enhanced the wilt incidence in wilt-susceptible cultivars only at 25 °C. Interaction
between the two pathogens on shoot and root weights was significant only at 20 °C, and F. o. ciceri
suppressed the nematode density at this temperature. Wilt incidence was greater in clayey (48% clay)
than in loamy sand (85% sand) soils. The nematode caused greater plant damage on loamy sand than
on clayey soil. Fusarium wilt resistance in Avrodhi and JG 74 was stable in the presence of M. javanica

Neutrino propagation and spin zero sound in hot neutron matter with Skyrme interactions
We present microscopic calculations of neutrino propagation in hot neutron
matter above nuclear density within the framework of the Random Phase
Approximation . Calculations are performed for non- degenerate neutrinos using
various Skyrme effective interactions. We find that for densities just above
nuclear density, spin zero sound is present at zero temperature for all Skyrme
forces considered. However it disappears rapidly with increasing temperature
due to a strong Landau damping. As a result the mean-free path is given, to a
good approximation, by the mean field value. Because of the renormalization of
the bare mass in the mean field, the medium is more transparent as compared to
the free case. We find, in contrast, that at several times nuclear density, a
new type of behavior sets in due to the vicinity of a magnetic instability. It
produces a strong reduction of the mean free path. The corresponding transition
density however occurs in a region where inputs from more realistic
calculations are necessary for the construction of a reliable Skyrme type
parametrization.Comment: 17 pages, 4 figure
Effects of biofertilizer containing N-fixer, P and K solubilizers and AM fungi on maize growth: A greenhouse trial.
An in vitro study was undertaken to evaluate the compatibility of indigenous plant growth promoting rhizobacteria (PGPR) with commonly used inorganic and organic sources of fertilizers in tea plantations. The nitrogenous, phosphatic and potash fertilizers used for this study were urea, rock phosphate and muriate of potash, respectively. The organic sources of fertilizers neem cake, composted coir pith and vermicompost were also used. PGPRs such as nitrogen fixer; Azospirillum lipoferum, Phosphate Solubilizing Bacteria (PSB); Pseudomonas putida, Potassium Solubilizing Bacteria (KSB); Burkholderia cepacia and Pseudomonas putida were used for compatibility study. Results were indicated that PGPRs preferred the coir pith and they proved their higher colony establishment in the formulation except Azospirillum spp. that preferred vermicompost for their establishment.

PROTECTIVE EFFECT OF AQUEOUS EXTRACT OF LEAVES OF MURRAYA KOENIGII, AGAINST ALUMINUM CHLORIDE-INDUCED OXIDATIVE STRESS IN RAT LIVER AND KIDNEY
Objective: The aim of the current study was to investigate the hepatoprotective, nephroprotective, and cholesterol-lowering activity of aqueous extract of Murraya koenigii (MK) leaves against AlCl3-induced oxidative stress in rats.
Methods: Wistar albino rats were distributed into six groups (6 each). Group I (control), and Group II administered with distilled water, and aluminum chloride (AlCl3), (40 mg/kg body weight [b.w], oral), respectively. Group III rats were treated with standard Vitamin E (100 mg/kg b.w, p.o) and AlCl3 (40 mg/kg b.w, oral). Group IV, V, and VI received aqueous extract of leaves of Murraya koenigii (AEMK) (100 mg/kg b.w, peroral [p.o], 200 mg/kg b.w, p.o, and 400 mg/kg b.w, p.o), respectively, for a period of 35 days.
Results: Histopathological examination was observed deformities in hepatic and renal tissues due to aluminum exposure which augment the aforementioned results. Coadministration of AEMK along with Al significantly restored the serum biomarkers to their near-normal levels and has the ability to overcome Al-induced oxidative stress, manifested by a significant reduction in hepatic and renal malondialdehyde level. It increased cellular antioxidant defense, particularly by increasing GPx, glutathione, GR, and catalase levels, preserved normal hepatic and renal histological architecture.
Conclusion: It could be concluded that AEMK has significant radical scavenging activity and can mop up Al-induced toxicity, suggesting hepatoprotective and nephroprotective potential
ANTI-PARKINSON ACTIVITY OF AQUEOUS EXTRACT OF LEAVES OF MURRAYA KOENIGII AGAINST PARAQUAT-INDUCED PARKINSONISM IN WISTAR RATS
Objective: The current study evaluates anti-Parkinson’s activity of aqueous extracts of leaves of Murraya koenigii (MK) (AEMK) against paraquat (PQ)-induced Parkinsonism in rats.
Methods: In this study, effects of MK (100, 200, and 400 mg/kg, p.o.) were studied using in vivo behavioral parameters such as catalepsy, muscle rigidity, and locomotor activity and its effects on neurochemical parameters malondialdehyde, catalase (CAT), glutathione (GSH) reductase, GSH peroxidase, and GSH in rats.
Results: Parkinson’s disease was induced by administering PQ 10 mg/kg b.w/i.p once in a week for 4 weeks. The increased cataleptic scores were significantly (p<0.001) found to be reduced, with the AEMK in a dose-dependent manner. Chronic administration of PQ significantly induced motor dysfunction (muscle rigidity and hypolocomotion), showed a significant increase in lipid peroxidation level, and depleted the levels of GSH, CAT, and reduced GSH. Daily administration of AEMK significantly improved motor performance and also significantly attenuated oxidative damage.
Conclusion: The study proved that MK treatment significantly attenuated motor defects and also protected the brain from oxidative stress

Not AvailableThe goal of improving rural livelihoods has now become a major research agenda in the country. This assumes greater importance in disadvantaged regions like the rainfed, arid, hilly and tribal areas where the vulnerability of the population to external shocks is high. This vulnerability needs to be addressed through imparting new skills to the poor, building of durable income generating assets, capacity to adapt to rapidly changing market environments and empowerment of women and farmer groups.NAIP Progra
Genetic Analysis of Pearl Millet [Pennisetum glaucum (L.) R. Br] Lines for Yield and Yield Contributing Traits
This investigation was conducted to study combining ability along with inheritance of grain yield and its component traits in 36 hybrids of pearl millet which were generated through line Ă— tester mating design using 12 male sterile lines and 3 restorers as parental material at IIMR, Hyderabad during kharif, 2022. These hybrids were evaluated in randomized block design with 3 replications during kharif, 2022 and summer, 2023 at IIMR, Hyderabad. In results, both GCA and SCA variances were found significant for majority of characters. The ratio of GCA and SCA variance indicated the predominance of non-additive gene action for all the characters studied except for panicle length and panicle width. GCA effects revealed that parents like 274A, 269A, 04999A and 260A (female) and 123R (male) were good general combiners for grain yield and some contributing characters. On the basis of SCA effects the crosses namely 252A Ă— 124R, 843-22A Ă— 124R, 843-22A Ă— 132R, 242A Ă— 123R, 264A Ă— 132R and 274A Ă— 123R were identified as superior for grain yield and related traits over the seasons. Therefore, it is advised that these parents and hybrids be used in the creation of fruitful hybrids as well as for population growth
