On a conjecture of the harmonic index and the minimum degree of graphs
Authors: Sun Xiaoling , Gao Yubin , Du Jianwei , Xu Lan
Published: April 2019

The harmonic index of a graph G is defined as the sum of the weights 2/
d(u)+d(v) of all edges uv of G, where d(u) denotes the degree of the vertex
u in G. Cheng and Wang [4] proposed a conjecture: For all connected graphs G
with n ? 4 vertices and minimum degree ?(G) ? k, where 1 ? k ? ?n2?+ 1,
then H(G) ? H(K*k,n-k) with equality if and only if G ? K*k,n-k. K*k,n-k is a complete split graph which has only two degrees, i.e. degree k
and degree n-1, and the number of vertices of degree k is n-k, while
the number of vertices of degree n-1 is k. In this work, we prove that
this conjecture is true when k ? n2, and give a counterexample to show that
the conjecture is not correct when k = ?n/2? + 1, n is even, that is k = n/2
+ 1.

Authors: Nikkhah A. , Davvaz B. , Mirvakili S.
Published: April 2019

The purpose of this paper is the study of hypergroups associated with
hypergraphs. In this regard, we construct a hypergroupoid by defining a
hyperoperation on the set of degrees of vertices of a hypergraph. We will
see that the constructed hypergroupoid is always an Hv-group. We will
investigate some conditions to have a hypergroup.

Authors: Naghi Monia , Mihai Ion , Uddin Siraj , Al-Solamy Falleh
Published: April 2019

In this paper, we introduce the notion of warped product skew CR-submanifolds
in Kenmotsu manifolds. We obtain several results on such submanifolds. A
characterization for skew CR-submanifolds is obtained. Furthermore, we
establish an inequality for the squared norm of the second fundamental form
of a warped product skew CR-submanifold M1 x fM? of order 1 in a Kenmotsu
manifold ?M in terms of the warping function such that M1 = MT x M?, where MT,
M? and M? are invariant, anti-invariant and proper slant submanifolds of ?M,
respectively. Finally, some applications of our results are given.
Existence of solutions for a class of variational-hemivariational-like inequalities in Banach spaces
Authors: Ceng Lu-Chuan , Yao Jen-Chih , Yao Yonghong
Published: April 2019

This paper is devoted to study the existence of solutions for a class of
variational-hemivariationallike inequalities in reflexive Banach spaces.
Using the notion of the stable (?,?)-quasimonotonicity, the properties of
Clarke?s generalized directional derivative and Clarke?s generalized
gradient, we establish some existence results of solutions when the
constrained set is nonempty, bounded (or unbounded), closed and convex.
Moreover, a sufficient condition to the boundedness of the solution set and a
necessary and sufficient condition to the existence of solutions are also
derived.
On the graph of modules over commutative rings II
Authors: Ansari-Toroghy Habibollah , Habibi Shokoufeh , Hezarjaribi Masoomeh
Published: April 2019

Let M be a module over a commutative ring R. In this paper, we continue our
study about the quasi-Zariski topology-graph G(?*T) which was introduced in
(On the graph of modules over commutative rings, Rocky Mountain J. Math.
46(3) (2016), 1-19). For a non-empty subset T of Spec(M), we obtain useful
characterizations for those modules M for which G(?*T) is a bipartite
graph. Also, we prove that if G(?*T) is a tree, then G(?*T) is a star
graph. Moreover, we study coloring of quasi-Zariski topology-graphs and
investigate the interplay between ?(G(?+T)) and ?(G(?+T)).

Mass partitions via equivariant sections of Stiefel bundles
Authors: Simon Steven
Published: April 2019

We consider a geometric combinatorial problem naturally associated to the
geometric topology of certain spherical space forms. Given a collection of m
mass distributions on Rn, the existence of k affinely independent regular
q-fans, each of which equipartitions each of the measures, can in many cases
be deduced from the existence of a Zq-equivariant section of the Stiefel
bundle Vk(Fn) over S(Fn), where Vk(Fn) is the Stiefel manifold of all
orthonormal k-frames in Fn, F = R or C, and S(Fn) is the corresponding unit
sphere. For example, the parallelizability of RPn when n = 2,4, or 8
implies that any two masses on Rn can be simultaneously bisected by each of
(n-1) pairwise-orthogonal hyperplanes, while when q = 3 or 4, the
triviality of the circle bundle V2(C2)=Zq over the standard Lens Spaces
L3(q) yields that for any mass on R4, there exist a pair of complex
orthogonal regular q-fans, each of which equipartitions the mass.
Chaotic behavior analysis and control of a toxin producing phytoplankton and zooplankton system based on linear feedback
Authors: Liu Yadong , Liu Wenjun
Published: April 2019

In this paper, we study the dynamic behavior and control of the
fractional-order nutrientphytoplankton-zooplankton system. First, we
analyze the stability of the fractional-order nutrient-plankton system and
get the critical stable value of fractional orders. Then, by applying the
linear feedback control and Routh-Hurwitz criterion, we yield the sufficient
conditions to stabilize the system to its equilibrium points. Finally, Under
a modified fractional-order Adams-Bashforth-Monlton algorithm, we simulate
the results respectively.
On an application of Herzberger’s matrix method to multipoint families of root-solvers
Authors: Dzunic Jovana , Petkovic Ljiljana , Petkovic Miodrag
Published: April 2019

An application of Herzberger?s matrix method, very rarely used in the topic
of multipoint methods for solving nonlinear equations, is presented. It is
shown that the area of application of Herzberger?s matrix method is wider
than it is presented in [J. Herzberger, ?ber Matrixdarstellungen f?r
Iterationverfahren bei nichtlinearen Gleichungen, Computing, 12 (1974)
215-222]. This method is applied for the determination of the order of
convergence of multipoint families of methods, Steffensen?s type and Newton?s
type, with and without memory. The advantage and the elegance of this method
arise from ease in handling matrices.
Some new inclusion sets for eigenvalues of tensors with application
Authors: Huang Zhengge , Wang Ligong , Xu Zhong , Cui Jingjing
Published: April 2019

In this paper, we are concerned with the eigenvalue inclusion sets for
tensors. Some new S-type eigenvalue localization sets for tensors are
employed by dividing N = {1,2,..., n} into disjoint subsets S and its
complement. Our new sets, are proved to be tighter than that newly derived
by Huang et al. (J. Inequal. Appl. 2016 (2016) 254). As applications, we can
apply the proposed sets for determining the positive (semi-)definiteness of
even-order symmetric tensors. Some examples are given to show the sharpness
of our new sets in contrast with the known ones, and verify the effectiveness
of those in identifying the positive (semi-)definiteness of tensors.

warped product pointwise pseudo-slant submanifolds of Sasakian manifolds by
giving some useful results, including a characterization.

points of the Ces?ro type mean of total asymptotically nonexpansive
mappings in CAT(0) spaces.
Mathematical analytic techniques for determining the optimal ordering strategy for the retailer under the permitted trade-credit policy of two levels in a supply chain system
Authors: Liao Jui-Jung , Huang Kuo-Nan , Chung Kun-Jen , Lin Shy-Der , Ting Pin-Shou , Srivastava H.M.
Published: April 2019

In this article, we explore a certain kind of two-level trade credit in order
to reflect the real-life situations. With this objective in view, we
consider the case when the supplier offers two-level trade credit for the
retailer for settling the account. If the retailer pays off all accounts at
the end of the first credit period, then he/she can utilize the sales
revenue to earn interest until the inventory cycle time. On the other hand,
if the retailer cannot pay off the unpaid balance at the end of the first
credit period, then he/she can decide to pay off the unpaid balance either
after the end of the first credit period or after the second credit period.
Here, in this situation, the retailer reduces the financed loan from
constant sales and revenue received gradually and he/she still can utilize
the sales revenue to earn interest when he/she pays off all accounts.
Maximizing the profit is used as the objective to develop the inventory
model. Based upon the obtained properties of the optimal solution, two
theorems are developed to determine the optimal replenishment policy.
Finally, computational developments are presented in order to illustrate
numerically the main theoretical results which are proven in this article by
using some mathematical solution procedures.
A new algorithm to fit exponential decays without initial Guess
Authors: Torvisco Juan , Rodríguez-Arias Fernández , Sánchez Javier
Published: April 2019

This paper deals with some nonlinear problems which exponential and
biexponential decays are involved in. A proof of the quasiconvexity of the
error function in some of these problems of optimization is presented. This
proof is restricted to fitting observations by means of exponentials having
the form f (t) = ?1 exp(kt) + ?2. Based on this quasiconvexity, we propose
an algorithm to estimate the best approximation to each of these decays.
Besides, the robustness of this algorithm allows us to avoid initial guess.
Generalized cascade orthogonal filters based on symmetric bilinear transformation with application to modeling of dynamic systems
Authors: Dankovic Nikola , Antic Dragan , Nikolic Sasa , Peric Stanisa , Spasic Miodrag
Published: April 2019

This paper presents generalized orthogonal cascade filters based on bilinear
transformation for mapping poles to zeroes and zeroes to poles in transfer
functions. The filters are orthogonal with respect to a new generalized
inner product. Actually, they represent a generalization of several classes
of existing traditional filters: the ones obtained by using linear
transformation of poles to zeroes, and the ones obtained by reciprocal
transformation of poles to zeroes. Generalized filters provide obtaining
more precise models of dynamic systems. This is verified by comparison
between models based on new filters and models based on classical filters.
Practical realization of these filters with adjusting parameters of bilinear
transformation and transfer function is performed. An application in
modeling continuous-time systems as a complex industrial process is given,
and it is shown that in that way we obtain more quality models than by using
the classical filters.

eigenvalue parameter. As an application, one example is also provided to
illustrate the validity of our main results.

solution of Helmholtz equation. Some of these conditions contain
singularities the regularization of which cannot be done by conventional
methods and is conducted by an original scheme.

?-para-holomorphic sectional curvature H, then it is a space of constant
sectional curvature and H = -1. Finally the object of the present paper is
to study a 3-dimensional para-Kenmotsu manifold, satisfying certain
curvature conditions. Among other, it is proved that any 3-dimensional
para-Kenmotsu manifold with ?-parallel Ricci tensor is of constant scalar
curvature and any 3-dimensional para-Kenmotsu manifold satisfying cyclic
Ricci tensor is a manifold of constant negative sectional curvature -1.

The Aspects of the 2018 Russian Presidential Election Campaign
Authors:   Saratov State Agrarian University, Fedorova-Kuznetsova Irina Vladimirovna
Published: April 2019

The research deals with the aspects of the 2018 Russian Presidential Election Campaign and com-pares it with previous ones. An attempt is made to both identify the novel elements of the last cam-paign and trace its continuous and traditional na-ture. For instance, the particular attention of authori-ties to voter turnout became a distinctive feature of the 2018 Russian Presidential Election Campaign. To this end, absentee ballots were cancelled, and citi-zens were able to vote at any polling station upon advance online registration. A week and disor-ganized protest movement was typical for the 2018 election campaign in contrast to the 2012 campaign. It may be influenced by shifting public opinion be-cause of the reunification of Crimea with Russia and the imposition of Western sanctions on the Russian Federation. The research notes that voters regard the 2018 election campaign as a transition to the 2024 election since it is Putin’s final presidential term, and further state development program will be implemented by a new leader of the country.

Hydrogen Atom Transfer Reaction Free Energy as a Predictor of Abiotic Nitroaromatic Reduction Rate Constants: A Comprehensive Analysis
Authors: Di Toro Dominic , Hickey Kevin P. , Allen Herbert E. , Carbonaro Richard F. , Chiu Pei C.
Published: April 2019

A linear free energy model is presented that predicts the second order rate constant for the abiotic reduction of nitroaromatic compounds (NACs). For this situation previously presented models use the one electron reduction potential of the NAC reaction. If such value is not available, it has been has been proposed that it could be computed directly or estimated from the electron affinity (EA). The model proposed herein uses the Gibbs free energy of the hydrogen atom transfer (HAT) as the parameter in the linear free energy model. Both models employ quantum chemical computations for the required thermodynamic parameters. The available and proposed models are compared using second order rate constants obtained from five investigations reported in the literature in which a variety of NACs were exposed to a variety of reductants. A comprehensive analysis utilizing all the NACs and reductants demonstrate that the computed hydrogen atom transfer model and the experimental one electron reduction potential model have similar root mean square errors and residual error probability distributions. In contrast, the model using the computed electron affinity has a more variable residual error distribution with a significant number of outliers. The results suggest that a linear free energy model utilizing computed hydrogen transfer reaction free energy produces a more reliable prediction of the NAC abiotic reduction second order rate constant than previously available methods. The advantages of the proposed hydrogen atom transfer model and its mechanistic implications are discussed as well.

Durante as atividades desta Subcomissão, um dos principais debates se deu em torno do aprimoramento do conceito de “função social da propriedade da terra” e do estabelecimento de limites ao tamanho das propriedades. Neste sentido, dois parlamentares do PMDB se situaram em lados opostos. De um lado, o deputado Oswaldo Lima Filho, de Pernambuco, relator da Subcomissão, no outro, o deputado mineiro Arnaldo Rosa Prata, ligado à União Democrática Ruralista. Assim, sinalizamos nosso interesse no aprofundamento desta discussão, tentando compreender como este conflito se insere no contexto histórico de abertura política, redemocratização e formação do pluripartidarismo.

Published: April 2019

Este artigo traz algumas importantes mudanças ocorridas na ACR entre 1978 e 1985, em consonância com o processo de reconquista da democracia no Brasil. Se no começo seu foco era particularmente voltado para questões sociais e religiosas, questões políticas, inclusive partidárias, passam a ser tratadas como sendo importantes e necessárias, acompanhando o processo de transformações que o país vivia. Isto aponta, também, uma tendência mais geral da Igreja Católica Progressista no Brasil naquele período.
“Instruir-se para instruir”: A Ação Católica Brasileira e a formação da Juventude Estudantil Católica no Brasil (1935-1966)
Authors: Maciel Carolina Maria Abreu
Published: April 2019

RESUMO: Este artigo tem como objetivo compreender como se deu a fundação e atuação da Ação Católica Brasileira (ACB), mais especificamente, do núcleo estudantil da organização leiga da Igreja Católica Apostólica Romana (ICAR), a Juventude Estudantil Católica (JEC). Primeiramente procuramos identificar como se baseou e desenvolveu a criação de um braço da Ação Católica no Brasil, visto que a AC era uma entidade de amplitude mundial, fundada em 1929, pelo Papa Pio XI. Para isso utilizaremos como fonte, para este primeiro momento de análise, alguns documentos oficiais da Igreja Católica, como as Encíclicas e, para um estudo mais aprofundado da AC, o Manual de Ação Católica, escrito por Luigi Civardi, que foi publicado no Brasil em 1937. Após perscrutar esse conteúdo que vai detalhar as bases doutrinárias desta organização de apostolado leigo passamos a analisar alguns documentos produzidos pela JEC, tanto pela Equipe Nacional quanto das nucleações regionais, como cartilhas, boletins e correspondências. Outra fonte de bastante relevância que nos auxiliou a conhecer mais a fundo a criação do primeiro núcleo de JEC do Brasil, como o cotidiano e desenvolvimento e atuação da entidade, durante as mais de três décadas de atividade, foi a obra de Frei Hilário Dick, JEC uma proposta que não morreu. Dessa forma, a proposta deste trabalho é identificar a trajetória entre a fundação da JEC, junto com a ACB, até 1966, ano que muitos reconhecem como o fim da Juventude Estudantil Brasileira.

Published: April 2019

Na Região Autónoma da Madeira, o Alojamento Local tem vindo a aumentar. Permitiu a reabilitação de imóveis degradados, oferta de alojamento em zonas atípicas e contribui de forma indireta para outros setores. Com aumento deste mercado torna-se importante compreender os intervenientes.

É neste âmbito que surgiu este estudo empírico. Através de um questionário administrado a 266 pessoas, procurou-se perceber qual o perfil do investidor neste tipo de mercado e mapear a distribuição do AL na RAM. No presente estudo foi possível demonstrar quais os concelhos com mais desenvolvimento de imóveis afetos ao AL (Funchal, Calheta e Santa Cruz). Também foi possível verificar que em todos os concelhos existem imóveis afetos a esta atividade, apresentando diferentes tipologias em zonas mais centrais (predominância de apartamentos) e zonas menos centralizadas (predominância de moradias).

Ficou demonstrado que 62% dos investidores são dotados de formação ao nível de ensino superior e numa perspetiva geral os inquiridos apresentam competências para atuar no mercado.
Types of Agriculture Land Tenancy System in Demak District, Demak Regency
Authors: Mouris Miranda Martiza , Setiawan Bakti
Published: April 2019

Agricultural tenancy system is a farmland management system commonly used by farmers. This system poses as a provider for rural community’s job opportunities and occupations. The purpose of this research is to identify types of tenancy system and the on-farm profiles in Demak District, Demak Regency. The connection between farmlands and these profiles may become a ground for mutual arrangement with the government in order to protect the existence of farmlands. The result of survey to 238 respondents in the district identified there are at least four types of tenancy system that exist in Demak District society, namely: (1) basic tenancy system, (2) partial tenancy system, (3) farm bussiness tenancy system, and (4) managerial tenancy system.  Furthermore, based on age characteristics and farming experience data, it is identified that there are possibilities of scarcity in farming profiles of the next generation, which may threat the existence of farmlands. Author argued that the scarcity may be due to job diversification in rural areas. This research suggests a new approach to implement the agricultural land protection policy by modifying one of the existing agricultural land tenancy systems into a contract based system with the government. The contract is aimed to formalize and bind on-farm profiles with their farmland, as well as to limit the number of them. Thus, other productive labor force may be shifted to another field for regional economic development.

Authors: DÜZGÜNER Vesile , ERBİL Nurcan
Published: April 2019

Valerianceae familyasına ait olan kediotu (Valeriana officinalis L.) yerel olarak Avrupa ve Asya’da bulunan çiçekli bir bitkidir ve çoğunlukla uykusuzluk hastalığı ve kaygı bozukluklarının tedavisi için kullanılmaktadır. Bu çalışmada Ardahan yöresinden toplanan kediotunun antioksidan ve antimikrobiyal aktiviteleri incelenmiştir. Kediotunun metanol/ethanol ekstraktlarının antimikrobiyal aktivitesi Pseudomonas aeroginosa (ATCC 9027), Staphylococcus aureus (ATCC 6538), Bacillus megaterium (DSM 32), Escherichia coli, Yarrovia lipolytica, Candida albicans ve Saccharomyces cerevisiae’ya karşı test edilmiştir. Bitkilerin Glutatyon (GSH) düzeyi spektrofotometrik olarak, total oksidan ve antioksidan kapasiteleri (sırasıyla TOK ve TAK) ise ELISA yöntemi ile ölçülmüştür. Kediotunun, bu çalışmada kullanılan test mikroorganizmalarına karşı hafif oranda antibakteriyel aktiviteye sahip olduğu tespit edilmiştir. Metanol ekstraktlarındaki GSH düzeyi etanol ekstraktlarından daha yüksek çıkmıştır. Benzer şekilde total antioksidan kapasite ölçümlerinde methanol ekstraktlarındaki değerler etanol ekstraktlarından fazla saptanmıştır. Sonuç olarak Valeriana officinalis’in yararlı etkilerini belirleyen antibakteriyal ve antioksidatif içeriklerinin etki mekanizması ile ilişkisinin in vitro çalışmalarla desteklenmesi gerektiği kanısına varılmıştır.

Authors: DOĞAN Nilgün
Published: April 2019

Hayvansal protein kaynaklı gıdalar,
gerek zihinsel gerekse bedensel gelişimde, dengeli beslenme için oldukça önem
arz etmektedir. Gelişmiş ülkelerin beslenme desenlerinde hayvansal kaynaklı
gıdalar ağırlıkta iken, FAO’ya göre Türkiye’de tahıl ve tahıl ürünleri en çok
tüketilen gıda grupları içerisinde ilk sırada yer almaktadır. Türkiye’de kişi
başına tüketilen 26 gr hayvansal proteinin %35’i etten sağlanmaktadır. Bu
tüketim düzeyi ile Türkiye, hayvansal kaynaklı tüketim bakımından dünya ile
kıyaslandığında oldukça geride kalmaktadır. Hayvansal kaynaklı proteinlerin
başında kırmızı et, tavuk eti ve özellikle sindirimi daha kolay, kalp
hastalıklarının azalmasına yardımcı olan, omega-3 içeren balık eti gelmektedir.
Bu araştırmada, TRA1 bölgesinde yer alan Erzurum, Erzincan ve Bayburt
illerindeki hanelerin tüketim eğilimleri belirlenerek dengeli ve kaliteli
beslenme açısından bölgenin mevcut durumu ortaya koyulmaya çalışılmıştır.
Toplamda 400 hane ile yüzyüze görüşmeler yapılarak mevcut tüketim deseni
hakkında bilgi toplanmıştır. Araştırma sonuçlarına göre; üç et çeşidini
tüketenlerin oranı Erzincan’da %70, Bayburt’ta %63,8 ve Erzurum’da %54,3 olarak
elde edilmiştir. Tüketenlerin içeresinde en yüksek tavuk eti tüketim oranı
(%35) Erzurum’da iken bunu sırasıyla Erzincan (%20,3) ve Bayburt (%6,7) takip
etmiştir. Kırmızı et ve balıketi tüketim oranları her üç ilde de birbirine
yakın oranda bulunmuştur.
Growth differentiation factor 15 — biomarker of poor prognosis in heart failure
Authors: A. E. Berezin  , O. V. Petyunina  , M. P. Kopytsya
Published: April 2019

Heart failure (HF) is a major factor contributing to premature death in patients with established cardiovascular (CV) disease. There is a large body of evidence that biological markers, primarily natriuretic peptides, galectin‑3, soluble ST2 and cardiac troponins, allow predicting poor clinical outcomes, particularly, heart failure (HF), in general population as well as in individuals with suspected or established CV diseases. Recent clinical trials have shown that abilities of these biomarkers are different regarding identification of morbidity and mortality risks, the latter depending on numerous factors, i.e. age, sex, comorbidities, treatment regime and phenotypes of HF. Of the biomarkers mentioned, only natriuretic peptides and ST2 are used for biomarker‑controlled therapy for heart failure, and their serial measurements do not enhance the prognostic effect in long‑term follow‑up, especially in patients with preserved left ventricular (LV) ejection fraction (LV). Growth and differentiation factor 15 (GDF‑15) belongs to the superfamily of growth factors β and regulates the function of mitochondria of a wide range of cells involved in inflammation, oxidative stress, apoptosis, immune responses, fibrosis, repair and malignancy, which allows using it for risk stratification in patients with CVD, in particular with HF. GDF‑15 is synthesized and released as a result of adaptation to stress. Its plasma level correlates directly with the severity of HF, the peak concentration of the N‑terminal fragment of the brain natriuretic peptide, the mortality rate from all causes. It has been suggested that adding GDF‑15 to the multimarker pool (highly sensitive C‑reactive protein and soluble ST2 with a galactin‑3/N‑terminal fragment of the brain natriuretic peptide or without it) can help predict HF and facilitate the differentiation of HF with preserved LV EF from HF with reduced/moderately reduced LV EF.
