Reasons of academic procrastination: self- regulation, academic self-efficacy, life satisfaction and demographics variables
(Elsevier Science Bv, 2014)The behavior of academic procrastination is quite common among students. Students can not show their real performances in learning processes and they fail because of procrastination behaviors. Determining the reasons of ... -
Recent developments about multivalued weakly Picard operators
(Belgian Mathematical Soc Triomphe, 2015)In the present paper, considering a recent technique, which is used by Wardowski [24] for fixed points of single-valued mappings, we give a new and general class of multivalued weakly Picard operators on complete metric ... -
Reconstruction of Baskakov operators preserving some exponential functions
(Wiley, 2019)The present paper deals with a new modification of Baskakov operators in which the functions exp(mu t) and exp(2 mu t), mu > 0 are preserved. Approximation properties of the operators are captured, ie, uniform convergence ... -
Recursion Formulas For G(1) And G(2) Horn Hypergeometric Functions
(Univ Miskolc Inst Math, 2015)The aim of this paper is to present various recursion formulas for Horn hypergeometric functions by the contiguous relations of hypergeometric series. These recursion formulas allow us to state the functions G(1) and G(2) ... -
Redescription of Zodariellum sungar (Araneae: Zodariidae) with the First Description of the Female
(Florida Entomological Soc, 2013)The redescription of Zodariellum sungar (Jocque, 1991), on the basis of newly collected material is provided. The female of this species, previously unknown, is described here for the first time. In addition, one new ... -
Reinvestigation of bromination of 8-substituted quinolines and synthesis of novel phthalonitriles
(Acg Publications, 2016)Bromination of a series of 8-substituted quinolines was reinvestigated and specified for optimum yields and isolation conditions. Mono bromination of 8-hydroxyquinoline (2a) and 8-aminoquinoline (2c) gave mixture of mono ... -
A Related Fixed Point Theorem for F-Contractions on Two Metric Spaces
(Hacettepe Univ, Fac Sci, 2019)Recently, Wardowski in [Fixed points of a new type of contractive mappings in complete metric spaces, Fixed Point Theory Appl. 2012] introduced the concept of F-contraction on complete metric space which is a proper ... -
Relation of the Nine Types of Temperament Model with Personality Disorders
