Antioxidant and antimicrobial potential of water lily extracts and their effects on the quality of frozen Nile tilapia (Oreochromis niloticus) fillets

open access: yesFood Science &Nutrition, Volume 11, Issue 1, Page 535-544, January 2023., 2023
Extension of shelf life using natural antioxidant like water lily extracts is desirable for highly perishable seafood preservation than the synthetic one. In this study, water lily ethanolic extract has considerable amount of antioxidant and antimicrobial potentiality, which effectively reduced the quality deterioration, inhibited the lipid oxidation ...

On the dark radiation role in the Hubble constant tension [PDF]

open access: yesarXiv, 2023
Dark radiation, parameterized in terms of $N_{\rm eff}$, has been considered many times in the literature as a possible remedy in alleviating the Hubble constant ($H_0$) tension. We review here the effect of such an extra dark radiation component in the different cosmological observables, focusing mostly on $H_0$.

Reusing Waste Coffee Grounds as Electrode Materials: Recent Advances and Future Opportunities

open access: yesGlobal Challenges, Volume 7, Issue 1, January 2023., 2023
Coffee industry produces more than 8 million tons of waste coffee grounds (WCG) annually. In recent decades, upcycling of WCG‐derived carbon into value‐added electrode materials has attracted growing interests owing to their low cost and high electrochemical properties.

Sterile neutrino production at small mixing in the early universe [PDF]

open access: yes, 2022
Sterile neutrinos can be produced in the early universe via interactions with their active counterparts. For small active-sterile mixing angles, thermal equilibrium with the standard model plasma is not reached and sterile neutrinos are only produced via flavor oscillations.

Meiotic behavior of economically important plant species: the relationship between fertility and male sterility [PDF]

open access: yesGenetics and Molecular Biology, 2000
Meiosis is an event of high evolutionary stability which culminates in a reduction of chromosome number. The normal and harmonious course of meiosis ensures gamete viability. The cytologic events of gametogenesis are controlled by a large number of genes that act from premeiotic to postmeiotic mitosis.

Stress Response of Aspergillus niger Spores to Copper Surfaces and the Implications for Antifungal Surface Functionalization

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the antifungal efficacy of ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) on copper, brass, and steel surfaces. Using Aspergillus niger as a model, the research highlights a 99% reduction in spore viability on 9 µm structured copper surfaces due to enhanced copper ion release. Scanning electron microscopy

Irreversibility scrutinization on EMHD Darcy–Forchheimer slip flow of Carreau hybrid nanofluid through a stretchable surface in porous medium with temperature‐variant properties

open access: yesHeat Transfer, Volume 52, Issue 1, Page 395-429, January 2023., 2023
Abstract The significance of hybrid nanofluids in controlling heat transmission cannot be overemphasized. Therefore, this article scrutinizes the electromagnetized flow of Carreau hybrid nanofluid towards a stretching surface in a Darcy–Forchheimer porous medium with the occurrence of slip conditions.

Optimal Sterilization Policies in Interdependent Economies [PDF]

open access: yes, 1997
In this paper, a two-country leader-follower model with imperfect asset substitution is used to derive the optimal sterilization coefficients for two-country flexible and fixed exchange rate regimes. It is found that, in general, incomplete sterilization

Use of Maximal Sterile Barriers during Central Venous Catheter Insertion: Clinical and Economic Outcomes [PDF]

open access: yesClinical Infectious Diseases, 2004
We performed a cost-effectiveness analysis to determine the effect of maximal sterile barriers (MSBs) on reducing central venous catheter (CVC)--related infections. Use of MSBs when placing CVCs may reduce the risk of infections but is more cumbersome, time-consuming, and expensive than other techniques.We developed a decision analytic model in which a
