Ralph Waldo Emerson as Nature Poet

Since nature inherently contains moral truth, knowledge and wisdom, the artist should rely on it, rather than convention, in shaping, formulating and appraising his work. Emerson maintains that literary works should not be only be evaluated according to artificial standards of tradition, but should rather be judged by nature since art is based organically on it. He shares with Coleridge the belief that literary forms should innately stem from nature instead of following mechanical laws of decorum. Emerson affirms that if we succeed in having a direct relation with the "basic forces" of nature, by retreating to a primitive, simple life, we will be able to reinvent genuine, organic forms (Matthiessen 133-6). In "Nature", Emerson further argues that nature provides us with language as well as with an explanation of the use of language. Every word in language is a symbol of a natural fact; for example, "right" is a sign for "straight" while "wrong" means "twisted". Similarly, we borrow the word "heart" to express emotion and the word "head" as analogous to thought. Both the abstract and the concrete find their roots in the visible forms of nature. Moreover, every natural fact corresponds to some spiritual fact. We symbolically use "light" and "darkness" to express knowledge and ignorance

Thermal conductivity of evolving quark-gluon plasma in the presence of a time-varying magnetic field

The effect of the temperature evolution of QGP on its thermal conductivity and elliptic flow is investigated here in the presence of a time-varying magnetic field. Thermal conductivity plays a vital role in the cooling rate of the medium or its temperature evolution. The magnetic field produced during the early stages of (non-central) heavy-ion collisions decays with time, where electrical conductivity plays a significant role. As the medium expands, the electrical and thermal properties change, reflecting the effect in various observables. In this study, we have calculated the thermal conductivity of the QGP medium, incorporating the effects of temperature and magnetic field evolution. We discovered that conductivity significantly depends on the cooling rate and its value increases due to temperature evolution. Furthermore, the influence of these evolutions on the elliptic flow coefficient is measured, and elliptic flow is found to decrease.Comment: 14 pages and 3-captioned figures, Submitted for publicatio

Impact of Medium Anisotropy on Quarkonium Dissociation and Regeneration

Quarkonium production in ultra-relativistic collisions plays a crucial role in probing the existence of hot QCD matter. This study explores quarkonia states dissociation and regeneration in the hot QCD medium while considering momentum anisotropy. The net quarkonia decay width ($\Gamma_{D}$) arises from two essential processes: collisional damping and gluonic dissociation. The quarkonia regeneration includes the transition from octet to singlet states within the anisotropic medium. Our study utilizes a medium-modified potential that incorporates anisotropy via particle distribution functions. This modified potential gives rise to collisional damping for quarkonia due to the surrounding medium, as well as the transition of quarkonia from singlet to octet states due to interactions with gluons. Furthermore, we employ the detailed balance approach to investigate the regeneration of quarkonia within this medium. Our comprehensive analysis spans various temperature settings, transverse momentum values, and anisotropic strengths. Notably, we find that, in addition to medium temperatures and heavy quark transverse momentum, anisotropy significantly influences the dissociation and regeneration of various quarkonia states.Comment: 9 pages and 4 captioned figure

Comparison of Radiography and Ultrasonography for Diagnosis of Diaphragmatic Hernia in Bovines

The present study was conducted on 101 animals suffering from thoracoabdominal disorders; out of which twenty seven animals (twenty six buffaloes and one cow) were diagnosed with diaphragmatic hernia based on clinical signs, radiography, ultrasonography, and left flank laparorumenotomy. Radiography alone confirmed diaphragmatic hernia in 18 cases (66.67%) with a sac-like structure cranial to the diaphragm. In 15 animals the sac contained metallic densities while in three cases a sac-like structure with no metallic densities was present. Ultrasonography was helpful in confirming diaphragmatic hernia in 23 cases (85.18%) and ultrasonographically reticular motility was evident at the level of 4th/5th intercostal space in all the animals. B+M mode ultrasonography was used for the first time for diagnosis of diaphragmatic hernia in bovines and the results suggested that ultrasonography was a reliable diagnostic modality for diaphragmatic hernia in bovines

J/ψJ/\psi and ψ\psi(2S) polarization in proton-proton collisions at the LHC energies using PYTHIA8

The production mechanisms of charmonium states in both hadronic and heavy-ion collisions hold great significance for investigating the hot and dense QCD matter. Studying charmonium polarization in ultra-relativistic collisions can also provide insights into the underlying production mechanisms. With this motivation, we explore the $J/\psi$ and $\psi$(2S) polarization in proton+proton collisions at $\sqrt{s}$ = 7, 8, and 13 TeV using a pQCD-inspired Monte-Carlo event generator called PYTHIA8. This work considers reconstructed quarkonia through their dimuons decay channel in the ALICE forward rapidity acceptance range of $2.5 < y_{\mu \mu} < 4$. Further, we calculate the polarization parameters $\lambda_{\theta}$, $\lambda_{\phi}$, $\lambda_{\theta \phi}$ from the polar and azimuthal angular distributions of the dimuons in helicity and Collins-Soper frames. This study presents a comprehensive measurement of the polarization parameters as a function of transverse momentum, charged-particle multiplicity, and rapidity at the LHC energies. Our findings of charmonium polarization are in qualitative agreement with the corresponding experimental data.Comment: 10 pages and 5-captioned figures. Submitted for publicatio

Impact of vorticity and viscosity on the hydrodynamic evolution of hot QCD medium

The strongly interacting transient quark-gluon plasma (QGP) medium created in ultra-relativistic collisions survive for a duration of a few fm/c. The spacetime evolution of QGP crucially depends on the equation of state (EoS), vorticity, viscosity, magnetic field, etc. In the present study, we obtain the QGP lifetime considering it as a 1+1-dimensionally (1+1) D expanding fluid by using second-order viscous hydrodynamics. We observe that the coupling of vorticity and viscosity significantly increases the lifetime of rotating QGP. Incorporating a static magnetic field along with vorticity and viscosity makes the evolution slower. However, for a non-rotating medium, the static magnetic field slightly decreases the QGP lifetime by accelerating the evolution process. We also report the rate of change of vorticity in the QGP medium, which can be helpful in studying the medium behavior in detail.Comment: 16 pages and 20 captioned figures. Submitted for publicatio

EFFECT OF EDUCATIONAL INTERVENTION MEASURES ON KNOWLEDGE ABOUT RABIES AND ITS PREVENTIVE MEASURES AMONG FINAL YEAR NURSING STUDENTS OF A TERTIARY CARE HOSPITAL IN CENTRAL INDIA

Background: Rabies continues to be a major public health challenge with around 55,000 deaths every year. Amongst the health care providers nursing personnel are often the first point of contact and hence need to be well trained in the management of rabies cases. Methods: The present study was an educational intervention study conducted among 100 final year nursing students of a Medical College Hospital to assess the knowledge regarding rabies and its transmission, first aid measures undertaken, and pre and post exposure prophylaxis measures employed to prevent the infection. Results: 66% of the students knew about the signs and symptoms of the disease, post intervention this increased to 87%. Knowledge regarding animal bites which transmit rabies improved by 86 % mode of transmission by 49 % and first aid measures undertaken following an animal bite by 12%. 15% of the students knew about the correct site and route of PEP; post intervention 91% knew about it, 87% increase was observed as regards the dose of vaccine to be administered and 73% students correctly knew about the PEP schedule post educational intervention. Knowledge regarding groups / individuals who need to receive pre-exposure prophylaxis increased by 33% and that of the schedule of pre-exposure prophylaxis by 53%. The mean pre-intervention score was 6.95 and mean post-intervention score was 13.51; the results being statistically significant. Conclusion: Substantial improvement in knowledge about the disease was noted amongst the nursing students following the educational intervention session
