Peroxidase induced oligo-tyrosine cross-links during polymerization of a-lactalbumin
No full textHorseradish peroxidase (HRP) induced cross-linking of proteins has been reported to proceed through formation of di-tyrosine cross-links. In the case of low molar mass phenolic substrates, the enzymatic oxidation is reported to lead to polymerization of the phenols. The aim of this work was to investigate if during oxidative cross-linking of proteins oligo-tyrosine cross-links are formed in addition to dityrosine. To this end, a-lactalbumin (a-LA) was cross-linked using horseradish peroxidase (HRP) and hydrogen peroxide (H2O2). The reaction products were acid hydrolysed, after which the cross-linked amino acids were investigated by LC-MS and MALDI-MS. To test the effect of the size of the substrate, the cross-linking reaction was also performed with L-tyrosine, N-acetyl L-tyrosinamide and angiotensin. These products were analyzed by LC-MS directly, as well as after acid hydrolysis. In the acid hydrolysates of all samples oligo-tyrosine (Yn, n = 3–8) was found in addition to di-tyrosine (Y2). Two stages of cross-linking of a-LA were identified: a) 1–2 cross-links were formed per monomer until the monomers were converted into oligomers, and b) subsequent cross-linking of oligomers formed in the first stage to form nanoparticles containing 3–4 cross-links per monomer. The transition from first stage to the second stage coincided with the point where di-tyrosine started to decrease and more oligo-tyrosines were formed. In conclusion, extensive polymerization of a-LA using HRP via oligo-tyrosine cross-links is possible, as is the case for low molar mass tyrosine containing substrates

Impact of Rice Husk Ash on Cement Concrete
No full textImpact of rice husk fiery debris on cement concrete is a lab give an account of cement concrete is that the consuming of rice husks RH has made a high pozzolanic reactivity and property. Indian standard code of practice for reinforced concrete and plain is 456 2000, prescribes utilization of rice husk fiery remains is influenced in the ignition and the temperature. The report clarifies about the entire photo of the lab report with rate esteem. Rice Husk Ash contains silica in undefined and profoundly cell frame, with 50 1000 m2 g surface zone. In this way, the utilization of rice husk fiery debris cement dealing with and enhanced strength, lessen the heat generation, thermal cracking and plastic shrinkage. This builds quality impermeability, improvement and toughness by reinforcing progress zone, changing the pore structure, obstructing the huge voids in the hydrated cement glue through pozzolanic response. Rice husk cinder limits antacid aggregate response, decreases development, shines pore structure and thwarts dissemination of soluble base particles to the surface of aggregate by micro porous structure.

Abstract
Climate change disproportionately affects developing countries due to their limited adaptive capacity, socio-economic constraints, and increased exposure to climate-related hazards. This paper investigates resilience and adaptation strategies through the lens of climate justice, highlighting the importance of equitable and inclusive approaches. Using a secondary research methodology, it synthesizes theoretical frameworks and empirical data from peer-reviewed literature, international reports, and climate finance databases. A quantitative analysis evaluates adaptation investments and their impact on reducing vulnerability, supported by numerical calculations and country-specific case studies. The study concludes with actionable policy recommendations aimed at achieving both sustainability and justice
Exchange-Coupled Bimagnetic Core–Shell Nanoparticles for Enhancing the Effective Magnetic Anisotropy
No full textMagnetic nanoparticles offer enormous possibilities of controlling the properties of magnetic materials due to their size and surface effects, including superparamagnetism, surface spin disorder, and surface anisotropy. Recently, the design and fabrication of novel materials based on bimagnetic nanoparticles provided novel strategies by incorporating interface effects. Therefore, the hysteretic behavior and the thermal stability of the magnetic moments can be tuned by controlling their composition, size, morphology, and interactions. This chapter focuses on the enhancement of the magnetic anisotropy due to the exchange coupling in bimagnetic nanoparticles synthesized by chemical colloidal methods. Various types of exchange-coupled bimagnetic nanoparticle systems are presented, and the different magnetization-reversal mechanisms are briefly discussed. Then, key aspects of the synthesis methods for obtaining core–shell nanoparticles are described, focusing on the heat-up thermal decomposition method. Finally, the anisotropy enhancement in antiferromagnetic/ferrimagnetic CoO-core/CoFe2O4-shell nanoparticles is presented and discussed as a case study.Fil: Lavorato, Gabriel Carlos.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
