New Jensen-type integral inequalities via modified (h, m)-convexity and their applications
(Universidad Comenius, 2023)This article presents new developments and applications of Jensen’s inequality. We explore various variations of Jensen’s inequality related to modified (h, m)-convex functions. The obtained results extend the applicability ... -
Some new Jensen–Mercer type integral inequalities are established via fractional operators
(MDPI AG, 2023)In this study, we present new variants of the Hermite–Hadamard inequality via non-conformable fractional integrals. These inequalities are proven for convex functions and differentiable functions whose derivatives in ... -
Weighted norm inequalities for Schrödinger operators on variable Lebesgue spaces
(Element Publishing house, 2024)In this work we show that many operators from harmonic analysis associated with the semigroup generated by the Schr ̈odinger operator L = −Δ +V in n , where n > 2 and the non–negative potential V belongs to the ... -
A note on the oscillatory nature of Lienard Equation
(Science Domain International, 2017)In this paper we consider the problem about the conditions on f(x), g(x) and a(t) to ensure that all solutions of (1) are continuable and oscillatory using non usual assumptions. -
Phospholipase A2 enhances the endothelial cell detachment effect of a snake venom metalloproteinase in the absence of catalysis
(Elsevier Ireland Ltd, 2015)Microvessel disruption leading to hemorrhage stands among the most dangerous consequences of envenomings by snakes of the family Viperidae. A PIII metalloproteinase (SVMP), balteragin, purified from the venom of the snake ... -
Fractional–order modeling and control of COVID-19 with shedding effect
(MDPI AG, 2023)A fractional order COVID-19 model consisting of six compartments in Caputo sense is constructed. The indirect transmission of the virus through susceptible populations by the shedding effect is studied. Equilibrium ... -
Some new estimates of integral inequalities and their applications
(National Academy of Sciences of Ukraine. Institute of Mathematics, 2024)We obtain several new integral inequalities in terms of fractional integral operators for the functions whose first derivatives satisfy either the conditions of the Lagrange theorem or the Lipschitz condition. In some ... -
Some refinements of the Hermite–Hadamard inequality with the help of weighted integrals
(National Academy of Sciences of Ukraine. Institute of Mathematics, 2023)By using the definition of modified (h, m, s)-convex functions of the second type, we present various refinements of the classical Hermite–Hadamard inequality obtained within the framework of weighted integrals. Throughout ... -
Integral inequalities for mappings whose derivatives are (h, m, s)−convex modified of second type via Katugampola integrals
(Universidad de Craiova. Departamentos de Matemáticas y de Ciencias de la Computación, 2022)In this paper, using the definition of functions (h,m,s)-convex modified of second type, various extensions of the classic Hermite-Hadamard Inequality are obtained using Katugampola integrals. In addition, we show that ... -
Some extensions of the Hermite-Hadamard inequalities for quasi-convex functions via weighted integral
(Universidad Católica del Norte, 2023)In this note, starting with a lemma, we obtain several extensions of the well-known Hermite-Hadamard inequality for convex functions, using generalized weighted integral operators. -
On generalizations of integral inequalities
(Universidad Estatal de Petrozavodsk, 2022)In the present study, several new generalized integral inequalities of the Hadamard and Simpson-type are obtained. The results were obtained for functions whose first and third derivatives are either convex or satisfy ... -
Classification of Argentinean Sauvignon blanc wines using UV spectroscopy and chemometric methods
(Institute of Food Technologists, 2013)Argentina is an important worldwide wine producer. In this country, there are several recognizable provinces that produce Sauvignon blanc wines: Neuquén, Río Negro, Mendoza, and San Juan. The analysis of the provenance ... -
South American snake venoms with abundant neurotoxic components. Composition and toxicological properties. A literature review
(Elsevier B.V., 2021)In South America there are three snake genera with predominantly neurotoxic venoms: Crotalus, Micrurus and Hydrophis, which include nine species/subspecies, 97 species and a single marine species, respectively. ... -
Physicochemical and biological characterization of nanovenoms, a new tool formed by silica nanoparticles and Crotalus durissus terrificus venom
(Elsevier B.V., 2020)Nanoparticles (NPs) are being studied due to their potential use as therapeutic and immunomodulatory tools, including their ability to transport antigens with the aim to induce a specific immune response. The production of ... -
Interacción entre poblaciones de Triatoma infestans y Triatoma sordida
(Universidade de São Paulo. Facultad de Salud Pública, 1994)Para conocer si se producía algún tipo de interacción entre poblaciones de Triatoma infestans y Triatoma sordida que convivían en una unidad experimental y explotaban el mismo recurso alimentario (ave) se las estudió ... -

Efecto de un tratamiento térmico sobre la calidad de pimientos cherry cortados refrigerados
(Universidad de la República. Facultad de Agronomía. Instituto Nacional de Investigación Agropecuaria, 2012-06)Se estudió el efecto de la aplicación de un tratamiento térmico (55 oC/60 s) sobre la evolución de parámetros de calidad de pimientos (Capsicum annuum, L. cv cherry) frescos cortados (descorazonados) almacenados durante ... -
Feeding ecology of two wild sympatric canids in protected areas of northeastern Argentina
(Zoological Society of London, 2024-11-18)The role of mesocarnivores in wildlife communities tends to be overlooked, which has led to a large gap in natural history knowledge. In northeastern Argentina, two mesocarnivore foxes, Cerdocyon thous and Lycalopex ... -
