Expansion of radio galaxies in a cosmologically evolving medium: Possible implications for the cosmic star-formation history
We compare earlier estimates of the volumes filled by lobes of radio galaxies
during the quasar era based upon non-evolving ambient media with new ones
assuming a strong cosmological evolution of the ambient medium. If the sources
remain active for over 10^8 years the volumes filled by them are found to be
comparable for the two scenarios. This strengthens our earlier inference that
much of the cosmic web of gaseous filaments, the site of galaxy formation, was
probably permeated by radio lobes during the quasar era and this could have
triggered extensive star formation and made large contributions to the spread
of magnetic fields and metals through the universe by z ~ 2.Comment: To appear in Bull. Astron. Soc. India; 10 pages, 3 Figures, basi.sty

Effects due to unconventional pairing in transport through a normal metalsuperconductor-normal metal hybrid junction
We explore transport properties of a normal metal-superconductor-normal metal
(NSN) junction, where the superconducting region supports mixed singlet and
chiral triplet pairings. We show that in the subgapped regime when the chiral
triplet pairing amplitude dominates over that of the singlet, a resonance
phenomena emerges out where all the quantum mechanical scattering probabilities
acquire a value of 0.25. At the resonance, crossed Andreev reflection mediating
through such junction, acquires a zero energy peak. This reflects as a zero
energy peak in the conductance as well in the topological phase when .Comment: Conference Proceeding
Occurrence of pinjalo snapper, Pinjalo pinjalo in the fishery of Maharashtra
On 06.12.03, ten numbers of pinjalo snapper. Pinjalo pinjalo were landed in the trawl catches at the New Ferry Wharf,Mumbai. Later two more numbers were
recorded from Sassoon Dock, Mumbai on
11.12.03. The depth of fishing was 40-60 m
in the fishing grounds off southwest of
Mumabi

A study to assess the level of knowledge regarding prevention and management of acute respiratory infection among mothers of children 0-5 years in selected hospital in Siliguri
Background: In developing countries like India acute respiratory infection (ARI) contributes in child mortality upto 75% and out of 10, 7 deaths are due to ARI. The knowledge of the mothers towards the disease is a significant determinant of child’s health.Methods: A descriptive cross-sectional study included 100 mothers of children 0-5 years admitted in pediatric ward and postnatal ward in selected hospital Siliguri during the year 2022 in the month of March. Data was collected using structured interview method.Results: 20% of mothers have good knowledge in prevention and 33% had good knowledge in management of ARI.Conclusions: As the leading cause of death among children, knowledge assessment about ARI among the mothers is very important, which helps for better understanding of the intensity of the problem
Nanomedicines for the management of diabetic nephropathy: present progress and prospects
Diabetic nephropathy (DN) is a serious microvascular consequence of diabetes mellitus (DM), posing an encumbrance to public health worldwide. Control over the onset and progress of DN depend heavily on early detection and effective treatment. DN is a major contributor to end-stage renal disease, and a complete cure is yet to be achieved with currently available options. Though some therapeutic molecules have exhibited promise in treating DN complications, their poor solubility profile, low bioavailability, poor permeation, high therapeutic dose and associated toxicity, and low patient compliance apprehend their clinical usefulness. Recent research has indicated nano-systems as potential theranostic platforms displaying futuristic promise in the diagnosis and treatment of DN. Early and accurate diagnosis, site-specific delivery and retention by virtue of ligand conjugation, and improved pharmacokinetic profile are amongst the major advantages of nano-platforms, defining their superiority. Thus, the emergence of nanoparticles has offered fresh approaches to the possible diagnostic and therapeutic strategies regarding DN. The present review corroborates an updated overview of different types of nanocarriers regarding potential approaches for the diagnosis and therapy of DN
