Cyanogenic Compounds, Physicochemical Parameters and Metals in Water From Cassava Processing Areas: A Study in the Brazilian Amazon, Using Multivariate Analysis

Environmental Toxicology, EarlyView.
ABSTRACT This study evaluated the water quality of artesian wells and effluents generated in cassava processing in a rural area of Bragança, Pará, with emphasis on physicochemical parameters, multielement composition, and cyanogenic compounds. The well water presented specific nonconformities, highlighting pH values below the recommended level and high

Sakaguchi type functions defined by balancing polynomials [PDF]

Mathematica Bohemica
The class of Sakaguchi type functions defined by balancing polynomials has been introduced as a novel subclass of bi-univalent functions. The bounds for the Fekete-Szegö inequality and the initial coefficients $\vert a_2\vert$ and $\vert a_3\vert$ have ...

Rb4CuSb2X12 (X = Cl, Br) as Novel Vacancy‐Ordered Quadruple Perovskites

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The vacancy‐ordered quadruple perovskites Rb4CuSb2X12 (X = Cl, Br) were crystallized from hydrohalic acid. Their crystal structures can be interpreted as new distortion variants of the perovskite structure with ordered vacancies. The electronic structure of Rb4CuSb2Br12 shows that the Br and Sb states form the valence band and the upper conduction band.

Applications of Bernoulli Polynomials and q²-Srivastava–Attiya Operator in the Study of Bi-Univalent Function Classes

Mathematics
The central focus of this study is the development and investigation of a generalized subclass of bi-univalent functions, defined using the q2-Srivastava–Attiya operator in conjunction with Bernoulli polynomials.

From Nominalisation to Passive in Old Tibetan: Reconstructing Grammatical Meaning in an Extinct Language1

Transactions of the Philological Society, EarlyView.
Abstract Based on an analysis of the Old Literary Tibetan corpus—a corpus of the oldest documented Tibetic language—the present study provides evidence that literary Tibetan v3 verb stems (commonly termed ‘future’) initially encoded passive voice. New arguments put forward in this article range from Trans‐Himalayan nominal morphology to early Tibetan ...

Faber polynomial coefficient bounds for a subclass of bi-univalent functions [PDF]

, 2016
In this work, considering a general subclass of bi-univalent functions and using the Faber polynomials, we obtain coefficient expansions for functions in this class.

Structural Basis for Trivalent Cross‐Linking of a Patient‐Derived IgE Antibody by the Major Peanut Allergen Ara h 2.0201

Allergy, EarlyView.
Graphical The crystal structure of a major peanut allergen Ara h 2.0201 in a complex with a human‐derived IgE Fab fragment has been determined. The immunocomplex shows the trivalent binding of Fabs, creating a cross‐linked structure effective in the formation of large complexes on the surface of effector cells. Hydroxylation of proline has implications

Simultaneous modification of Thermotoga maritima encapsulin subunits to produce multivalent nanoparticle vaccines for non‐typhoidal Salmonella enterica

The FEBS Journal, EarlyView.
This study investigates the modularity of encapsulin—a protein nanoparticle—by simultaneously inserting up to four distinct Salmonella epitopes within the encapsulin subunit. The encapsulin variants were transiently expressed in plants where they assembled into nanoparticles; however, their accumulation and stability varied depending on the ...

Coefficient estimates for a certain subclass of bi-univalent functions

Le Matematiche, 2016
Summary: In the present investigation, we find estimates on the coefficients \(|a_2|\) and \(|a_3|\) for functions in the function class \(S_\Sigma(\lambda,h)\). The results presented in this paper improve or generalize the recent work of \textit{N. Magesh} and \textit{J. Yamini} [Int. Math. Forum 8, No. 25--28, 1337--1344 (2013; Zbl 1283.30030)].
