On a class of a boundary value problems involving the p(x)-Biharmonic operator
No full textOur aim is to establish the existence of weak solution for a class of Robin problems involving fourth order operator. The nonlinearity is superlinear but does not satisfy the usual Ambrosetti-Rabinowitz condition.The proof is made with and without variational structure
Odd harmonious labeling of super subdivisión graphs
No full textA graph G(p, q) is said to be odd harmonious if there exists an injection ?: V (G) → {0, 1, 2, · · · , 2q − 1} such that the induced function ?∗: E(G) → {1, 3, · · · , 2q − 1} defined by ?∗(uv) = ? (u) + ? (v) is a bijection. In this paper we prove that super subdivision of any cycle Cm with m ≥ 3 ,ladder, cycle Cn for n ≡ 0(mod 4) with K1,m and uniform fire cracker are odd harmonious graphs
Algorithm for the generalized Φ-strongly monotone mappings and application to the generalized convex optimization problem
No full textLet E be a uniformly smooth and uniformly convex real Banach space and E∗ be its dual space. We consider a multivalued mapping A : E → 2E∗ which is bounded, generalized Φ-strongly monotone and such that for all t > 0, the range R(Jp+tA) = E∗, where Jp (p > 1) is the generalized duality mapping from E into 2E∗ . Suppose A−1(0) = ∅, we construct an algorithm which converges strongly to the solution of 0 ∈ Ax. The result is then applied to the generalized convex optimization problem
Even vertex equitable even labeling for snake related graphs
No full textLet G be a graph with p vertices and q edges and A = {0,2,4,···, q+1} if q is odd or A = {0,2,4,···,q} if q is even. A graph G is said to be an even vertex equitable even labeling if there exists a vertex labeling f : V (G) → A that induces an edge labeling f∗ defined by f∗(uv)=f(u)+f(v) for all edges uv such that for all a and b in A, |vf(a)−vf(b)|≤1 and the induced edge labels are 2,4,···,2q, where vf(a) be the number of vertices v with f(v)=a for a ∈ A. A graph that admits even vertex equitable even labeling is called an even vertex equitable even graph. In this paper, we prove that S(D(Qn)), S(D(Tn)), DA(Qm) ʘ nK1, DA(Tm) ʘ nK1, S(DA(Qn)) and S(DA(Tn)) are an even vertex equitable even graphs
Pebbling on zig-zag chain graph of n odd cycles
No full textGiven a distribution of pebbles on the vertices of a connected graph G, a pebbling move on G consists of removing two pebbles from one vertex and placing one pebble on an adjacent vertex. The pebbling number of G, f (G), is the least n such that any distribution of n pebbles on G allows one pebble to be reached to any specified, but an arbitrary vertex. Similarly, the t−pebbling number of G, ft(G), is the least m such that from any distribution of m pebbles, we can move t pebbles to any specified, but an arbitrary vertex. In this paper, we determine the pebbling number, and the t−pebbling number of the zigzag chain graph of n copies of odd cycles
Violência contra a mulher e enfrentamento na percepção dos profissionais de saúde da atenção básica
Get PDFObjective: To know the perception of primary care physicians and nurses about violence against women and their coping. Method: A cross-sectional study with a qualitative approach, carried out with professionals from the Family Health Strategy of a municipality in the interior of Ceará, Brazil, who answered a semi-structured interview. The discourses were organized through thematic categorization and analyzed based on relevant literature. The data was also processed in the IRAMUTEQ software. Results: Twelve health professionals, four physicians and eight nurses, who describe the main manifestations of violence in women participated in the study. They point out that for various reasons, among them the low qualification, they do not have capacity to act on complaints of violent acts, emphasizing educational activities as important the recognition of the grievance. As for the notification, it has proved a difficulty for its operation, associated with the fear of retaliation due to the breach of professional secrecy. The word cloud processed by IRAMUTEC reinforces the results, by highlighting the word "no", demonstrating that professionals do not feel safe when confronted with these cases, and most of them do not report the grievance. Conclusions: The professionals do not act effectively in coping with violence against women in basic care.
Objetivo: Conocer la percepción de médicos y enfermeros de la atención básica sobre violencia contra la mujer y su enfrentamiento. Método: Estudio transversal, con abordaje cualitativo, realizado con profesionales de la Estrategia Salud de la Familia de un municipio del interior de Ceará, Brasil, que respondieron a una entrevista semiestructurada. Los discursos fueron organizados por mediodecategorización temática y analizados con base en la literatura relevante. Los datos también se procesaron en el software IRAMUTEQ. Resultados: Participaron de la investigación 12 profesionales de salud, cuatro médicos y ocho enfermeros, que describen las principales manifestaciones de violencia en las mujeres. Resaltan que, por motivos diversos, entre ellos la poca calificación, no poseen capacidad para actuar ante quejas de actos violentos, resaltando las actividades educativas como importantes el reconocimiento del agravio. En cuanto a la notificación, se reveló una dificultad para su operacionalización, asociada al temor de represalia por la quiebrade secreto profesional. La nube de palabras procesada por IRAMUTEC refuerza los resultados, al revelar destaque para la palabra "no", demostrando que los profesionales no se sienten seguros frente al enfrentamiento de estos casos, no habiendo en su mayoría lanotificación del agravio. Conclusiones: Los profesionales de salud no actúan de manera efectiva en el enfrentamiento de la violencia contra la mujer en la atención básica.Objetivo: Conhecer a percepção de médicos e enfermeiros da atenção básica sobre violência contra a mulher e seu enfrentamento.

I-statistical limit points and I-statistical cluster points
No full textIn this paper we have extended the notion of statistical limit point as introduced by Fridy[8] to I-statistical limit point of sequences of real numbers and studied some basic properties of the set of all Istatistical limit points and I-statistical cluster points of real sequences including their interrelationship. Also introducing additive property of I-asymptotic density zero sets we establish I-statistical analogue of some completeness theorems of R
(p, q)-Lucas polynomials and their applications to bi-univalent functions
No full textIn the present paper, by using the Lp,q,n(x) functions, our methodology intertwine to yield the Theory of Geometric Functions and that of Special Functions, which are usually considered as very different fields. Thus, we aim at introducing a new class of bi-univalent functions defined through the (p, q)-Lucas polynomials. Furthermore, we derive coefficient inequalities and obtain Fekete-Szegö problem for this new function class
Graceful centers of graceful graphs and universal graceful graphs
No full textIn this paper we define graceful center of a graceful graph. We proved any graph G which admits α-labeling has at least four graceful centers. We also defined a new strong concept of universal graceful graph. Some results on ring sum of two graphs for their graceful labeling are proved
