Impact of Nuclear Deformation on Neutron Dripline Prediction: A Study of Mg Isotopes
We have employed the relativistic Hartree-Bogoliubov (RHB) model with density-dependent meson-exchange interaction and separable pairing to investigate neutron dripline mechanisms for heavy Mg isotopes. In the present study, 40Mg is predicted to be dripline nuclei. The calculations are carried out by taking axial deformation into account. An investigation of shape transition is also done for even-even 32-42Mg isotopes. Our prediction for neutron dripline for 40Mg is consistent with some recent studies
The Interaction of Display Advertisement and E-Wom on Omnichannel Purchase Intention Using Sem: an Age Moderation Effect
Purpose: This study looks at how display advertisements affect customers' Omni-buy intentions and the impact of e-WOM in determining if this influence is reflected in their purchase intentions.
Theoretical framework: Consumers' daily lives have grown more reliant on display advertising. Consumers depend on the Internet as a source of readily accessible information regarding advertising and businesses. Consequently, a customer becomes linked and an omnichannel shopper, intending to purchase products both online and offline. Electronic word of mouth (e-WOM) has also emerged as a powerful force that must be understood in the context of the omnichannel buyer.
Design/methodology/approach: A survey was performed to confirm the study's assumptions. Consumers who purchase fashion products omnichannel were polled for information. A questionnaire of 28 questions was developed for the study. The questionnaire includes questions about the respondent's age, gender, and educational level.
Findings: The results of the study show that there is a link between display advertising, e-WOM, and Omni-Online Purchase Intention. Several suggestions are produced to assist managers in navigating their brand's online presence in a manner that fits their customers' Omni-purchase intention.
Research, Practical & Social Implication: Through this investigation, the prevalence of many display ads on consumer purchase intention on the omnichannel market is determined, which contributes to the literature on advertising efficiency.
Originality/value: This study would most likely propose a method for market communication to determine how different types of display advertisements influence consumer purchase intentions, allowing firms to better manage the customer experience
A Clinical Study of Gud-Amalaka Yoga in Garbhini Mutrakrichra w.s.r to Urinary Tract Infections during Pregnancy
Healthy mother and healthy baby are foremost aim of antenatal care. Progressive anatomical and physiological changes during pregnancy are not only confined to the genital organs however within other systems of the body too, some may be felt as discomfort by a pregnant woman. A pregnant woman having pain or burning micturition, fever with chills, nausea, vomiting and cloudy urine having bad smell can be diagnosed as having Urinary Tract Infection (UTI). UTI is most common bacterial infection encountered during Pregnancy and troublesome to the woman suffering from it. Pyelonephritis, premature delivery and other risk such as PROM, IUGR etc. can be the long term result of UTI hence prompt attention is requisite. In the present study Gud-Amalaka Yoga has been tried in 15 patients for evaluation of its clinical efficacy and adverse / side effects if any. It was observed that Gud-Amalaka Yoga showed better results (25% patients were moderately improved, 75% patients were mildly improved). None of the patient reported any adverse effect during or after the treatment
Nuclear shape evolution and shape coexistence in Zr and Mo isotopes
The phenomena of shape evolution and shape coexistence in even-even
Zr and Mo isotopes is studied by employing covariant
density functional theory (CDFT) with density-dependent point coupling
parameter sets DD-PCX and DD-PC1, and with separable pairing interaction. The
results for rms deviation in binding energies, two-neutron separation energy,
the differential variation of two-neutron separation energy, and rms charge
radii, as a function of neutron number, are presented and compared with
available experimental data. In addition to the oblate-prolate shape
coexistence in Zr isotopes, the correlation between shape transition
and discontinuity in the observables are also examined. A smooth trend of
charge radii in Mo isotopes is found to be due to the manifestation of
triaxiality softness. The observed oblate and prolate minima are related to the
low single-particle energy level density around the Fermi level of neutron and
proton respectively. The present calculations also predict a deformed bubble
structure in Zr isotope.Comment: this preprint contains incomplete data and some mistake
Deformation Effect on Proton Bubble Structure in N = 28 Isotones
Purpose: To study the effect of nuclear deformation on proton bubble structure of N = 28 isotones and and compare it with the spherical limits. The reduction of depletion fraction due to deformation can be explained by studying the relative differences in the central densities.Methods: In this work, we have employed relativistic Hartree-Bogoliubov (RHB) model withdensity-dependent meson-exchange (DD-ME2) interaction and separable pairing interaction. We have performed axially constrained calculations to investigate the deformed proton bubble structure in 40Mg, 42Si, 44S, and 46Ar, isotones of N = 28 shell closure.Results: We have observed that the nuclear deformation play againsts the formation of bubble structure. In the spherical limits, the isotones of N = 28 shell closure have pronounced bubble structure with large value of depletion fraction. But, the increase in deformation leads to the disappearance of bubble structure. The internal densities in deformed nuclei are found to increase with deformation which can be related to the decrease in depletion fraction.Conclusion: By using RHB model, we have investigated the ground state and proton bubble structure of N = 28 isotones. In 44S, and 46Ar, the 2s1/21d3/2 states get inverted due to the weakning of spin-orbit strength. Due to strong dynamical correlations, arising from deformation, the central depletion of proton density is greatly affected in these isotones. The decrease in depletion fraction can be related to increase in the internal density due to deformatio
Study of the profile of stroke in a tertiary-care hospital in the sub-Himalayan region in north India
Background: Rapid urbanization of rural areas is predicted to increase the incidence of risk factors for vascular events
such as stroke among the ruralites. A different culture, beliefs, terrain, and climatic conditions of Himachal Pradesh may
have an impact on the profile of stroke.
Objectives: To study the profile and the various risk factors of stroke in the sub-Himalayan region of north India.
Material and Methods: It was an observational cross-sectional study conducted at the Department of Medicine,
R.P. Government Medical College, Kangra, Himachal Pradesh, for a duration of 12 months, from June 2012 to May 2013.
Consecutive patients presenting to the hospital with signs and symptoms of stroke were included in the study. Detailed
history and clinical examination was carried out in all patients. CT scan, routine blood examination, and lipid profile were
evaluated in all patients.
Results: Total number of patients who presented with stroke in a year was 374. It formed 4.0% of the total hospital
admissions in medical wards. The mean age of stroke patients was 66.17±12.9 years. Of the total patients, 254 (67.9%)
were males and 120 (32%) were females; 127 patients (33.9%) presented between 6 am and 12 pm. The majority of
patients presented in winter months, from November to January. Average delay in the presentation to hospital was 29 h.
Only 79 (21.1%) patients presented within 3 h. Among the patients, 342 (91.4%) belonged to rural area, 61.4% had an
infarct, and 38.6% had intracerebral bleed. The most common symptoms reported were weakness in 276 (73%) followed
by speech abnormality in 53%. Hypertension as a risk factor was found in 174 (46.5%); 155 patients (41.4%) were
smokers; and diabetes was present in 61 patients (16.4%). Average cholesterol level was 176±54.99 mg/dl, and average
triglyceride level was 339 mg/dl.
Conclusions: The major strength in our study was the predominance of rural population. The state has witnessed an
increase in the incidence of stroke. Elderly population is predominantly affected. Average delay in presentation was 29 h,
which is substantially high. Majority of the events occurred in winter months
Palynological diversity of highly medicinal rare, endangered, and threatened plants from Western Himalaya, India
The present study investigated the palynological diversity of highly medicinal Rare, Endangered, and Threatened (RET) plant species dwelling in higher altitudes of Western Himalaya, India. The pollen morphology of 32 plant species covering 29 genera, 23 families, and 18 orders of Angiosperms was analyzed by Light Microscopy (LM) and Scanning Electron Microscopy (SEM). The families of the studied plant species have been arranged and discussed following the evolutionary sequence as per the updated version of Angiosperm Phylogeny Group ІV. The studied pollen characters were found to be helpful in the delimitation of taxa at the species level. In the studied monocots, the species belonging to order Zingiberales, Asparagales, and Liliales followed the general trend of having primitive inaperturate to advance monosulcate pollen except for Alismatales which had inaperturate pollen and placed after the orders mentioned above in the APG ІV classification system. The pollen aperture of the eudicot group in the present study followed the evolutionary pattern from tricolpate to tricolporate and triporate, which corroborated previous reports. All the investigated species of both monocot and eudicot groups had monad pollen units suggesting their primitiveness on the evolutionary scale except for the Rhododendron companulatum (Ericales), having evolutionarily advanced tetrad arrangement. The current study found primitive exine ornamentation in Ranunculales to advance in Asterales, Lamiales, Gentianales, and Boraginales and confirms the results of the previous studies. The data on the pollen morphological features of the studied species generated in the present study will help understand these important high-altitude plant species' reproductive biology and conservation aspects
Relativistic Mean Field Model parameterizations in the light of GW170817, GW190814, and PSR J0740 + 6620
Three parameterizations DOPS1, DOPS2, and DOPS3 (named after the Department
of Physics Shimla) of the Relativistic Mean Field (RMF) model have been
proposed with the inclusion of all possible self and mixed interactions between
the scalar-isoscalar (\sigma), vector-isoscalar (\omega) and vector-isovector
(\rho) mesons up to quartic order. The generated parameter sets are in harmony
with the finite and bulk nuclear matter properties.
A set of Equations of State (EOSs) composed of pure hadronic (nucleonic)
matter and nucleonic with quark matter (hybrid EOSs) for superdense
hadron-quark matter in \beta-equilibrium is obtained. The quark matter phase is
calculated by using the three-flavor Nambu-Jona-Lasinio (NJL) model. The
maximum mass of a non-rotating neutron star with DOPS1 parameterization is
found to be around 2.6 M for the pure nucleonic matter which satisfies
the recent gravitational wave analysis of GW190814 Abbott et al.,(2020) with
possible maximum mass constraint indicating that the secondary component of
GW190814 could be a non-rotating heaviest neutron star composed of pure
nucleonic matter. EOSs computed with the DOPS2 and DOPS3 parameterizations
satisfy the X-Ray observational data and the recent observations of GW170817
maximum mass constraint of a stable non-rotating neutron star in the range 2.01
\pm 0.04 - 2.16 \pm 0.03 M\odot and also in good agreement with constraints on
mass and radius measurement for PSR J0740+6620 (NICER) Riley et al., L27
(2021)}, Miller et al., (2021). The hybrid EOSs obtained with the NJL model
also satisfy astrophysical constraints on the maximum mass of a neutron star
from PSR J1614-2230 and Demorest et al., (2010) .We also present the results
for dimensionless tidal deformability, which are consistent with
the waveform models analysis of GW170817.Comment: 14 Pages, 10 Figures. arXiv admin note: text overlap with

Study of Photoluminescence Behaviour of Porous Silicon Samples Prepared at 20 mA Current Density
The paper presents a study on a series of porous silicon films of various thicknesses, prepared at 20 mA current density using a photoluminescence fitting model to determine the average crystallite size of sphe-rical shaped interconnected silicon quantum dots. Discrepancy in photoluminescence behavior of the samples is well explained with this model.

Observational constraint from the heaviest pulsar PSR J0952-0607 on the equation of state of dense matter in relativistic mean field model
In the present work, we constrain the equation of the state of dense matter
in the context of heaviest observed neutron star mass M = 2.35 M for the black widow pulsar PSR J0952-0607. We propose three
interactions HPU1, HPU2 and HPU3 (named after Himachal Pradesh University)for
the relativistic mean field model which include different combinations of
non-linear, self and cross-couplings among isoscalar-scalar ,
isoscalar-vector and isovector-vector meson fields up to the
quartic order. These interactions are in harmony with the finite nuclei and
bulk nuclear matter properties. The equations of state computed by using newly
generated interactions for the -equilibrated nucleonic matter satisfy
the heaviest observed neutron star mass M = 2.35 M
for the black widow pulsar PSR J0952-0607. The results for the radius
() and dimensionless tidal deformability ()
corresponding to the canonical mass are also presented and agree well with the
GW170817 event and astrophysical observations. The radius of
neutron star mass is predicted to be in the range = 12.98 -13.09 Km
which also satisfies the NICER observations by Miller et al. (2021) and Riley
et al.(2021). A covariance analysis is also performed to assess the theoretical
uncertainties of model parameters and to determine their correlations with
nuclear matter observables.Comment: 19 pages, 12 Figures. arXiv admin note: substantial text overlap with
