Effect of Digestate on growth and production of rice under rice – wheat cropping system

Field experiments were conducted during rainy seasons of 2017 and 2018 at National Wheat Research Program (NWRP), Bhairahawa to identify the suitable age and appropriate dose of digestate/biogas slurry regarding yield maximization of rice (cv. Ram dhan). The experiment compared the effect of different age [5 days (fresh), 90 days (3 months) and 180 days (6 months)] and dose (0, 5, 10 and 15 t ha-1) of digestate/biogas slurry on rice yield. The experiment was laid out in Randomized Complete Block design (RCBD) with three replications. Grain yield of rice was significantly higher (4.5 t ha-1) with the application of biogas slurry of 5 days than 90 days (4.3 t ha-1) age, in 2017 A. D. Similarly, yield was significantly higher (4.6 t ha-1) with the application of biogas slurry 5 days than of 90 days (4.5 t ha-1) age, in 2018.  Yield due to the application of biogas slurry of 5 days was equal to the yield resulted from the use of biogas slurry of 180 days in 2017 and 2018.  The pooled analysis showed that the yield with the application of biogas slurry of 5 days age was significantly higher (4.6 t ha-1) than the yield due to the application of biogas slurry of 90 (4. 4 t ha-1) and 180 days (4.5 t ha-1) age. The yield of rice has been found increasing significantly as the dose of biogas slurry was incremented from 0 t ha-1   to 15 t ha-1 in 2017, 2018 and in pooled analysis. The yield of rice was significantly higher (4.6 t ha-1)   in 2018 than in 2017 (4.4 t ha-1), in pooled analysis. Thus, the use of biogas slurry of the age of 5 days with the dose of 15 t ha-1 produced the  higher grain yield of rice.&nbsp

Graded level of nitrogen and mulching effect on growth and yield parameters of tomato in Arghakhanchi, Nepal

A field experiment was carried out to find out the effect of different levels of nitrogen and mulching on growth and yield parameters of tomato (Solanum lycopersicum Mill.) var. VL443 at commercial tomato farm in Sandhikharkha, Arghakhanchi from February – June 2022. The eight treatments were laid out in two factorial RCBD with three replications. The treatment combinations were T1 (Non-mulching with 0 kgha-1), T2 (Non-mulching with 50 kgha-1), T3 (Non- mulching with 100 kgha-1), T4 (Non-mulching with 150 kgha-1), T5 (Mulching with 0 kgha-1), T6 (Mulching with 50 kgha-1), T7 (Mulching with 100 kgha-1), and T8 (Mulching with 150 kgha-1). Growth parameters, yield, and yield attributing traits were recorded. The result indicated that the 150 kgha-1 dose of N application contributes to the higher plant height (178.13 cm), the number of leaves (47.83), fruit length (72.50 mm), fruit diameter (58.83 mm), Individual fruit weight (71.67 g) and yield (2.51 kg/ plant). Similarly, plastic mulch contributes significantly higher plant height (173.6 cm), the number of leaves (47.30), fruit length (68.84 mm), fruit diameter (54.20 mm), Individual fruit weight (72.52 g) and yield (2.53 kg/ plant) as compared to non-mulched condition. Furthermore, fruit yield per hectare in mulching with 150 kg-1 plot was significantly higher in comparison to non-mulching with 0 kgha-1 plot. So, the application of 150 kgha-1 nitrogen along with plastic mulching is recommended to increase the yield of tomatoes under the plastic tunnels in Arghakhanchi

Electronic and magnetic performance of MoS2 monolayer via Tc & Nb impurities defect and water adsorption

This study examined the effect of Tc & Nb impurity atoms on MoS2 (Tc-MoS2 & Nb-MoS2 ), and adsorption of water molecule on impurities defected MoS2 (Tc-W-MoS2 & Nb-W-MoS2) material from first-principles calculations. By the estimation of their ground state energy and binding energy, they are stable 2D materials. From band structure and density of states (DoS) calculations, Tc & Nb impurities affect the nature of pristine MoS2. It is found that Tc-MoS2 has n-type & Nb-MoS2 has p-type semiconducting nature. Water interaction on Tc-MoS2 & Nb-MoS2 slightly changes the electronic properties and impacts the bandgap, which enhanced the electronic performance of material than that of pristine MoS2. The magnetic properties of Tc-MoS2, Nb-MoS2, Tc-W-MoS2, and Nb-W-MoS2 are analyzed and found to exhibit an uneven distribution of up-spin and down-spin states of electrons in the orbital of atoms near the Fermi level. It reflects that they have magnetic  properties. The non-magnetic MoS2 material changes in to weak magnetic defected-MoS2 materials due to the presence of Tc, Nb and adsorbed water molecule. It means, impurity defects add to magnetic properties of pristine MoS2. Magnetic properties on defected MoS2 occurred due to the dominant contributions of spin states of 4d-orbital of Mo, Tc, Nb atoms, and 3p-orbital of S atoms in the structures. This study highlights the impact of Tc & Nb impurity atoms and adsorbed water molecule on impurities defected MoS2. The studied materials have potential applications in the fields of catalysis, nanoelectronics, biomedicine, and magnetic sensors on the basis of their electronic and magnetic properties

Phenylalanine-Rich Peptides Potently Bind ESAT6, a Virulence Determinant of Mycobacterium tuberculosis, and Concurrently Affect the Pathogen's Growth

BACKGROUND:The secretory proteins of Mycobacterium tuberculosis (M. tuberculosis) have been known to be involved in the virulence, pathogenesis as well as proliferation of the pathogen. Among this set, many proteins have been hypothesized to play a critical role at the genesis of the onset of infection, the primary site of which is invariably the human lung. METHODOLOGY/PRINCIPAL FINDINGS:During our efforts to isolate potential binding partners of key secretory proteins of M. tuberculosis from a human lung protein library, we isolated peptides that strongly bound the virulence determinant protein Esat6. All peptides were less than fifty amino acids in length and the binding was confirmed by in vivo as well as in vitro studies. Curiously, we found all three binders to be unusually rich in phenylalanine, with one of the three peptides a short fragment of the human cytochrome c oxidase-3 (Cox-3). The most accessible of the three binders, named Hcl1, was shown also to bind to the Mycobacterium smegmatis (M. smegmatis) Esat6 homologue. Expression of hcl1 in M. tuberculosis H37Rv led to considerable reduction in growth. Microarray analysis showed that Hcl1 affects a host of key cellular pathways in M. tuberculosis. In a macrophage infection model, the sets expressing hcl1 were shown to clear off M. tuberculosis in much greater numbers than those infected macrophages wherein the M. tuberculosis was not expressing the peptide. Transmission electron microscopy studies of hcl1 expressing M. tuberculosis showed prominent expulsion of cellular material into the matrix, hinting at cell wall damage. CONCLUSIONS/SIGNIFICANCE:While the debilitating effects of Hcl1 on M. tuberculosis are unrelated and not because of the peptide's binding to Esat6-as the latter is not an essential protein of M. tuberculosis-nonetheless, further studies with this peptide, as well as a closer inspection of the microarray data may shed important light on the suitability of such small phenylalanine-rich peptides as potential drug-like molecules against this pathogen

STRUCTURAL AND ELECTROMAGNETIC STUDY OF THIN AND THICK RE-Ba-Cu-O (RE = RARE EARTH) SUPERCONDUCTOR TAPES FABRICATED BY METAL ORGANIC CHEMICAL VAPOR DEPOSITION WITH AND WITHOUT BUFFER MODIFICATION

High temperature superconducting (HTS) tapes are being developed for a wide range of energy and magnetic applications. One of the challenges in their large scale deployment has been the cost associated with their fabrication. In this study, a high growth rate metal organic chemical vapor deposition (MOCVD) process is used to investigate the development of structural and electromagnetic properties of thick RE-Ba-Cu-O (REBCO, RE = rare earth) HTS films on biaxially-textured substrates. REBCO films are deposited as a thickness gradient (thickness ranging from 0 nm to almost 150 nm) on biaxially-textured flexible templates to understand structural properties development of films in their early stage of nucleation and growth. This work is then extended to fabricate thick films of almost 3 μm to achieve high critical currents. The thick films are deposited as a multi-layered structure and chemical-mechanical polishing of the deposited film has been employed following deposition of each layer to obtain suitable surface for subsequent REBCO layer’s deposition. This method has been shown to achieve tapes (2.86 μm thickness) with high engineering critical current density in the temperature range of 50 – 65 K and applied magnetic field range of 3 – 5 T. Another aspect of HTS films explored in this study is pre-fabrication of nanodefects which provides the opportunity to grow nanodefects independent of superconducting film growth. Metallic nanorods have been grown on biaxially-textured substrates by two methodologies namely, ‘electron beam-assisted deposition’ and ‘electrodeposition’ methods. Microstructural and electromagnetic properties of REBCO films with prefabricated metallic nanorods have been investigated.Electrical and Computer Engineering, Department o

A known theorem, Nigam (2010) dealing with the degree of approximation of conjugate of a signal belonging to Lipξ(t)-class by (E,1)(C,1) product summability means of conjugate series of Fourier series has been generalized for the weighted W(Lr,ξ(t)), (r≥1),(t>0)-class, where ξ(t) is nonnegative and increasing function of t, by En1Cn1~ which is in more general form of Theorem 2 of Nigam and Sharma (2011)

Degree of Approximation of Functions f

A new estimate for the degree of approximation of a function f˜∈Hω class by (Np·E1) means of its Fourier series has been determined. Here, we extend the results of Singh and Mahajan (2008) which in turn generalize the result of Lal and Yadav (2001). Some corollaries have also been deduced from our main theorem
