Influence of Direct Saponification Conditions on Sterol Yield and Composition of the Unsaponifiable Fraction of the Microalga Isochrysis galbana and the Seaweed Ascophyllum nodosum

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Saponification is a key step for recovering the unsaponifiable fraction (USF) of lipids, which contains bioactive sterols, tocopherols, and carotenoids. This study optimized direct saponification conditions (50–300 g L−1 KOH; 60°C–100°C) to recover sterol‐rich USFs from the microalga Isochrysis galbana and the brown seaweed Ascophyllum nodosum,

Still on the same page: A gender comparison of the top 100 picture books from the UK and China published 2011–2020

open access: yesChildren &Society, EarlyView., 2023
Abstract As a primary source for the early ages, picture books guide preschool children's gender perception through stories and illustrations. However, previous studies have criticised an overall gender inequality in children's picture books. Compared to the increasing attention on gender diversity in the UK picture book industry, there has been little

Tanda tangan Digital Menggunakan Algoritme Keccak dan RSA

open access: yesJurnal Nasional Teknik Elektro dan Teknologi Informasi, 2016
Just like conventional signatures, digital signatures can be used to prove the authenticity of a document in digital form. In addition, digital signatures can also be used to prove the validity of the author of the document, so that the author of the ...

Integer factoring and compositeness witnesses

open access: yesJournal of Mathematical Cryptology, 2020
We describe a reduction of the problem of factorization of integers n ≤ x in polynomial-time (log x)M+O(1) to computing Euler’s totient function, with exceptions of at most xO(1/M) composite integers that cannot be factored at all, and at most x exp −cM ...

Polyurethane Foams From a Triblock Copolymer Polyol With CO2‐Derived, High‐Tg Polycarbonate Segments

open access: yesJournal of Applied Polymer Science, EarlyView.
Polyurethane foam (PUF) properties are tuned by incorporating polyol with 0–15 wt% CO2‐derived poly(cyclohexene carbonate) (PCHC) segments (Tg = 104°C). Network PUFs are synthesized using CO2‐derived triblock copolymer polyol with PCHC hard segments and a polycaprolactone soft segment.

Statistical shape modeling of the human inner ear through micro‐computed tomography imaging

open access: yesThe Anatomical Record, EarlyView.
In this study, 54 cadaveric temporal bone specimens underwent high‐resolution micro‐CT imaging. Images were semi‐automatically segmented and converted to 3D surface mesh models for morphological measurement and analysis. Statistical shape models were created for the inner ear, cochlea, and vestibular system, as well as for sex‐ and side‐based subgroups.

Arthroscopic Bursal Acromial Reconstruction With a Porcine Extracellular Matrix Graft

open access: yesArthroscopy Techniques, EarlyView.
Abstract Reinsertion of superior or posterosuperior rotator cuff ruptures in the elderly is often not possible. Patients can be left with symptoms of pain, loss of strength, and active range of motion. Bursal acromial reconstruction is an anchorless operative treatment method for painful, irreparable superior or posterosuperior rotator cuff ruptures in

Design of azine antioxidants for sustainable biodiesel: integrating structural characterization and molecular modeling

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The growing global demand for sustainable energy solutions has intensified the search for renewable alternatives to fossil fuels, with biodiesel emerging as a promising candidate due to its biodegradability and lower emissions. However, its large‐scale application is limited by low oxidative stability, which compromises storage and performance.

Simple Backdoors on RSA Modulus by Using RSA Vulnerability

open access: yesIEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2009
This investigation proposes two methods for embedding backdoors in the RSA modulus N=pq rather than in the public exponent e. This strategy not only permits manufacturers to embed backdoors in an RSA system, but also allows users to choose any desired public exponent, such as e=216+1, to ensure efficient encryption.
