Soil quality deterioration, especially in intensive cropping system has become a serious problem for crop productivity. Consequently, strategies for sustainable crop production and soil health are urgently required. Therefore, a field experiment was conducted to study the impact of organic and inorganic nutrient sources on yield attributes and yield of maize-mustard cropping system during two consecutive kharif and rabi seasons of 2019-20 and 2020-21, respectively. The experiment was laid out in randomized block design assigning eight treatments of organic and inorganic nutrient sources comprising of (T1) RDF (120:60:40 kg N:P2O5:K2O ha-1), (T2) RDF + Zn, (T3) RDF + S, (T4) RDF + Zn + S, (T5) RDF + VC (5 t ha-1), (T6) RDF + VC (10 t ha-1), (T7) RDF + FYM (5 t ha-1) and (T8) RDF + FYM (10 t ha-1) and were replicated thrice. The results reported that the higher yield attributes and yield of maize viz., number of cobs plant-1, number of seeds cob-1, cob length, seed yield, stover yield and biological yield and for mustard viz., siliquae plant-1, number of seeds siliquae-1, length of siliquae, seed yield, stover yield and biological yield were recorded with application of RDF + VC (10 t ha-1) which was statistically at par with RDF + FYM (10 t ha-1). However, seed index/test weight and harvest index of maize-mustard cropping was failed to show any significant effect due to above treatments.

Two dimensional semiconductors have attracted considerable attention owing to their exceptional electronic and optical characteristics. However, their practical application has been hindered by the limited light absorption resulting from their atomically thin thickness and low quantum yield. A highly effective approach to manipulate optical properties and address these limitations is integrating subwavelength plasmonic nanostructures with these monolayers. In this study, we employed electron beam lithography and electroplating technique to fabricate a gold nanodisc (AuND) array capable of enhancing the photoluminescence (PL) of monolayer MoS$_2$ giantly. Monolayer MoS$_2$ placed on the top of the AuND array yields up to 150-fold PL enhancement compared to that on a gold film. We explain our experimental findings based on electromagnetic simulations.

Background: Osteoarthritis is more common in females. It is because osteoarthritis in post-menopausal women is associated with higher body weight, higher subcutaneous fat, calcium deficiency and weaker muscles linked to hormonal changes. The purpose of this study was to evaluate the role of high tibial osteotomy fixed with angle stable plate in treatment of osteoarthritis of knee. Material and Methods: In our study 10 cases were operated by modified coventry technique, 10 cases were operated by open wedge osteotomy with non locking plates and bone graft and 104 cases were operated by medial open wedge osteotomy and iliac graft secured by locking plate. In these cases full weight bearing was allowed at 8 week, 6 week and 3rd post operative day respectively. Radiographical analysis include post operatively change in tibio-femoral angle. Mean follow up of these cases was 2 year. Results: In our study thee knee pain and function score were significantly improved (p value

Aim: To improve the clinical outcomes and to detect the significant predictors of outcome of rotator cuff repair, such as age, sex, side, tear size, fixation methods, smoking, and associated pathology have been investigated in the Indian population. Methods: Forty patients (27 male and 13 female) were included in the study who had complete degenerated rotator cuff tear, managed by arthroscopic single or double row repair technique and follow up till one year at a single institution. Postoperatively, patients were followed up regularly for 4 weeks, and at the final follow-up evaluated using a modified UCLA score. Physical examination and range of motion were analyzed and documented. Results: More than 87.5% of the patients showed good and excellent results. Thirty patients (75%) showed good results, 3 patients (7.5%) showed excellent results. There were no statistically significant relations of outcome with age, sex, side of the tear, size of tear, alcohol or smoking. Patients showed a 65% drop sign negative compared to a 35% drop sign negative cases which are statistically significant. Belly press test was negative in all patients. Mean UCLA score of both favorable and unfavorable results in terms of improvement of post-operative score compared to pre-operative UCLA score was statistically significant. Conclusions: We conclude that the functional outcome was very satisfactory with excellent results. Our study found that post-operative clinical outcomes are not associated with age, sex, side, and size of the tear. Our results depicted that the arthroscopic rotator cuff repair could be the considerable option for repairing rotator cuff repair.

Strong coupling of excitons to optical cavity modes is of immense importance to understanding the fundamental physics of quantum electrodynamics at the nanoscale as well as for practical applications in quantum information technologies. There have been several attempts at achieving strong coupling between excitons in two dimensional semiconductors such as transition metal dichalcogenides (TMDCs) and photonic quasi-bound states in the continuum (BICs). We identify two gaps in the platforms for achieving strong coupling between TMDC excitons and photonic quasi-BICs: firstly, in the studies so far, different cavity architectures have been employed for coupling to different TMDCs. This would mean that typically, the fabrication process flow for the cavities will need to be modified as one moves from one TMDC to the other, which can limit the technological progress in the field. Secondly, there has been no discussion of the impact of fabrication imperfections in the studies on strong coupling of these subsystems so far. In this work, we address these two questions by optimizing a cavity with the same architecture which can couple to the four typical TMDCs (MoS$_2$, WS$_2$, MoSe$_2$, WSe$_2$) and perform a detailed investigation on the fabrication tolerance of the associated photonic quasi-BICs and their impact on strong coupling.

Anterior cruciate ligament injury is one of the most common injuries around knee and poses quiet a lot management controversies. Anterior cruciate ligament has a pivot role in function and stability of the knee joint along with all other ligaments, being a prime stabilizer preventing the anterior translation of tibia over femur. Acute anterior cruciate ligament injury causes recurrent episodes of instability, pain and decreased motion. Anterior cruciate ligament reconstruction allows return to pre injury levels even in athletes, delays development of early osteoarthritis and reestablish the stability of the joint. Graft fixation during ACL reconstruction can be achieved with use of either metal screws or bio absorbable screws. Bio absorbable screws usage provide better visibility in postoperative MRI and also avoid removal at later stage. However there are controversies regarding the ideal graft, ideal fixation device, ideal time and technique of reconstruction. In this study we have compared the metal and bio absorbable screw for fixing the graft and reported the result.

The present investigation entitled “Effect of Zn and FYM application on soil properties and performance of mustard crop (Brassica juncea L.)’’Involved field experimentation conducted during Rabi season of year 2017-18. There are six treatments with three replication are T1 (Control), T2 (RDF+5kgZnha-1), T3 (RDF+5kgZn ha-1+10tFYMha-1) T4 (RDF+10kgZnha-1), T5 (RDF+10kg Zn ha-1+10tFYMha-1), T6 (RDF+15kgZn ha-1), T7 (RDF+15kgZn ha-1+10tFYMha-1). The recommended dose of fertilizers is 60kg N ha-1, 40kgP2O5 ha-1, 40kgK2O ha-1. The growth attribute like plant height (181.80), number of branch plant (15.73) number of siliqua plant-1 (48.53) number of grains siliqua-1 (17.33) are higher in the treatment T7 RDF+15kgZn ha-1+10tFYMha-1. The highest grain and straw yield was obtained by T7 RDF+15kgZn ha-1+10tFYMha-1 i.e. 5.25 qha-1 and 23.68 qha-1. The treatment RDF+15kgZn ha-1+10tFYMha-1 is far better than any other treatments.

Phase transition and current of planar clusters with loops of Josephson $\pi$ junction is of great importance for application in the adiabatic quantum computation devices (AQC). Each $\pi$-ring possesses an orbital moment with a current. The orientation of these orbital moments is altered by self-interactions and controlled with a bias current. In the current research, we construct the phase diagram of semi-hydrogenated SiB (H-SiB) semiconductor using a two-dimensional (2D) Ising model with considering nearest-neighbor and diagonal interactions of spin planes on the on the hexagonal lattice. Our findings reveal that by decreasing temperature, two phase transitions of order and disorder occur and at low temperatures a glassy state appears, where this model maps to spin qubit. We theoretically study the magnetostriction effect by considering of laser electromagnetic field coupled to the spin planes of electric polarization of magnetic insulator for both unstrained and strained H-SiB monolayers. The dynamic of laser-spin coupling and spin current shows nonlinear optical effects and high-harmonic generation (HHG) under both terahertz (THz) and gigahertz (GHz) electromagnetic waves. The findings of this research open an avenue for experimentalists how to detect HHG in the topological insulators, Dirac systems, Mott insulators, and superconducting memories.

2D Ruddlesden Popper perovskites have been extensively studied for their exceptional optical and electronic characteristics while only a few studies have shed light on their mechanical properties. The existing literature mainly discusses the mechanical strength of single crystal perovskites, however a systematic study towards structure tunability of 2D perovskite thin films is still missing. In this study, we report the effect of number of inorganic layers `n' on elastic modulus of Butylammonium based 2D, quasi-2D perovskites and 3D perovskite using nanoindentation technique. The experimental results have also been substantiated using first principle density functional theory calculations. Understanding the mechanical behaviour of 2D Ruddlesden Popper perovskites thin films in comparison with conventional 3D perovskite offers intriguing insights into the atomic layer dependent properties and paves the path for next generation mechanically durable novel devices.

The recent discovery of natural biaxial hyperbolicity in van der Waals crystals, such as $\alpha$-MoO$_3$, has opened up new avenues for mid-IR nanophotonics due to their deep subwavelength phonon-polaritons. However, a significant challenge is the lack of active tunability of these hyperbolic phonon polaritons. In this work, we investigate heterostructures of graphene and $\alpha$-MoO$_3$ for actively tunable hybrid plasmon phonon polariton modes via electrostatic gating in the mid-infrared spectral region. We observe a unique propagation direction dependent hybridization of graphene plasmon polaritons with hyperbolic phonon polaritons for experimentally feasible values of graphene chemical potential. We further report an application to tunable valley quantum interference in this system with a broad operational bandwidth due to the formation of these hybrid modes. This work presents a lithography-free alternative for actively tunable, anisotropic spontaneous emission enhancement using a sub-wavelength thick naturally biaxial hyperbolic materials.

Monolayer transition metal dichalcogenides (1L-TMDs) have tremendous potential as atomically thin, direct bandgap semiconductors that can be used as convenient building blocks for quantum photonic devices. However, the short exciton lifetime due to the defect traps and the strong exciton-exciton interaction in TMDs has significantly limited the efficiency of exciton emission from this class of materials. Here, we show that exciton-exciton dipolar field interaction in 1L-WS2 can be effectively screened using an ultra-flat Au film substrate separated by multilayers of hexagonal boron nitride. Under this geometry, dipolar exciton-exciton interaction becomes quadrupole-quadrupole interaction because of effective image dipoles formed inside the metal. The suppressed exciton-exciton interaction leads to a significantly improved quantum yield by an order of magnitude, which is also accompanied by a reduction in the exciton-exciton annihilation (EEA) rate, as confirmed by time-resolved optical measurements. A semiclassical model accounting for the screening of the dipole-dipole interaction qualitatively captures the dependence of EEA on exciton densities. Our results suggest that fundamental EEA processes in the TMD can be engineered through proximal metallic screening, which represents a practical approach towards high-efficiency 2D light emitters.

Background: The posteromedial fragment of tibial plateau fracture remains unrecognized for a long time, leading to inadequate fixation with conventional methods and resulting in early varus collapse. So our study is to observe any significant change in functional and radiological outcome in tibial condylar fracture with posteromedial fragment fixed with buttress plates. Materials and methods: We studied 20 patients of tibial plateau fracture with posteromedial fragment fixed with buttress plate at Narayan Medical College and Hospital, Jamuhar, Sasaram, from first march 2017 to 28 February 2018. This study was a prospective observational study. Direct posterior approach in prone were employed in six patients and posteromedial approach in supine employed in 14 patients. Early knee mobilisation started on 1st day weight bearing restricted for 11-13 weeks postoperatively. Minimum 6 months follow up done. Rasmussen clinical and radiological scoring system was used.Results: Age of the patients ranged from 18-70 years with most of patients belong to 31- 50yrs of age group who are more prone for road traffic accidents. The majority of the patients were male (M: F = 3:1). The majority of the fractures were found to be type 4(30%) type5 (30%) and type6 (40%) of Schatzker’s classification. The functional and radiological outcome were comparable and no statistical difference was found with other study (p>0.05).Conclusion: Fixation of posteromedial fragment of tibial plateau fracture with buttress plate provides high union rates, acceptable complications rates as well as satisfactory clinical outcome and radiological outcome.

The aim of this study is to compare and evaluate functional, clinical and radiological outcome achieved by open reduction and internal fixation by Philos plate & percutaneous k-wire fixation of proximal humerus fracture in the elderly patients. In conclusion, locking Compression plate has a distinct advantage in treatment of proximal humeral fractures. This is due to angular stability, compression of fragment particularly in comminuted fractures and in Osteoporotic bones in elderly patients, thus allowing early mobilization. Percutaneous k-wire fixation can be a viable option in elderly patients where several comorbidities. They are particularly useful where we are dealing with patients who have constraint of finances and anesthestic risks of long hours of surgery.

Background: Vertebral fractures are the most common type of osteoporotic fractures. These are developing into a significant health problem worldwide as about 30% of the patients above 50 years suffer from a fracture secondary to osteoporosis. Osteoporotic vertebral fractures may be treated with rest and analgesics. Some fractures may also require surgery. Percutaneous procedure like vertebroplasty and kyphoplasty done under local anaesthesia can reduce the pain and restore height of vertebral body without need for an open surgery. The aim of the study was to assess the clinical and radiological outcomes following unilateral percutaneous vertebroplasty under local anaesthesia. Methods: 21 patients who underwent unilateral vertebroplasty for symptomatic osteoporotic compression fracture between August 2019 and July 2020 were included in the study. Unilateral vertebroplasty using an 11-gauge trocar through transpedicular technique was performed under c-arm guidance. Patient was mobilized as soon as tolerated. Oswestry disability index and visual analogue scale were assessed pre-operatively, in the immediate post-op and at 1-year follow up. Results: There were 15 females and 6 males. The mean age was 70.04±6.07 years. The pre-op ODI score was 76.8±7.6. The pre-op VAS score was 7.66±0.71. The average time period from fracture to vertebroplasty is 4.19±3.19 days. The immediate post-operative VAS score was 5.76±0.8 and the ODI score was 62.85±7.17. The VAS at final follow up was 1.23±1.19. ODI at final follow up was 9.04±3.19. There was a showed a significant improvement when preoperative, immediate post-operative ODI and VAS scores and final follow up (p

In this paper, we present a novel route to tunable spontaneous valley coherence in heterostructures of two dimensional valleytronic materials with other layered materials hosting anisotropic polaritonic modes. We first discuss the dependence of this coherence on the conductivity tensor of the anisotropic part of a general heterostructure and on its geometrical configuration. Subsequently, we propose two implementations - one, using anisotropic plasmons in phosphorene and another with hyperbolic phonon polaritons in MoO3. In both these systems we show for the first time electrostatic tunability of the spontaneous valley coherence achieving unprecedented values of up to 80% in the near to mid infrared wavelengths at room temperature. The tunability of this valley coherence shown in these heterostructures will enable the realization of active valleytronic quantum circuitry.

Black phosphorus presents a very anisotropic crystal structure, making it a potential candidate for hyperbolic plasmonics, characterized by a permittivity tensor where one of the principal components is metallic and the other dielectric. Here we demonstrate that atomically thin black phosphorus can be engineered to be a hyperbolic material operating in a broad range of the electromagnetic spectrum from the entire visible spectrum to ultraviolet. With the introduction of an optical gain, a new hyperbolic region emerges in the infrared. The character of this hyperbolic plasmon depends on the interplay between gain and loss along the two crystalline directions., Comment: Article 6 pages, 4 figures; supplemental material 6 pages, 4 figures

A generalized macroscopic nonlocal theory of sound propagation in rigid-framed porous media saturated with a viscothermal fluid has been recently proposed, which takes into account both temporal and spatial dispersion. Here, we consider applying this theory, which enables the description of resonance effects, to the case of sound propagation through an array of Helmholtz resonators whose unusual metamaterial properties, such as negative bulk moduli, have been experimentally demonstrated. Three different calculations are performed, validating the results of the nonlocal theory, related to the frequency-dependent Bloch wavenumber and bulk modulus of the first normal mode, for 1D propagation in 2D or 3D periodic structures., National Science Foundation (U.S.) (Grant N00014-13-1-0631)

Two-dimensional optical materials, such as graphene, can be characterized by surface conductivity. So far, the transformation optics schemes have focused on three-dimensional properties such as permittivity ϵ and permeability μ. In this Letter, we use a scheme for transforming surface currents to highlight that the surface conductivity transforms in a way different from ϵ and μ. We use this surface conductivity transformation to demonstrate an example problem of reducing the scattering of the plasmon mode from sharp protrusions in graphene., National Science Foundation (U.S.) (Grant CMMI-1120724), United States.
