It is well known that even extremely limited centerembedding causes people to have difficulty ill comprehension, but that leftand right-branching constractions produce no such effect. If the difficulty in comprehension is taken to be a result of processing load, as is widely assumed, then measuring the processing load induced by a parsing strategy on these constructions may help determine its p...

the aim of this study was to determine the relationship between entrepreneurial personality characteristics and small and medium-sized sport enterprises start-up (smses). the methodology of this study was descriptive-correlation. population consisted of small and medium-sized sport enterprises (n=1500) and their owners and/or managers were randomly selected as the sample (n=258). for data colle...

running the industrial components at a proper temperature is always a big challenge for engineers. internal combustion engines are among these components in which temperature plays a big role in their performance and emissions. with the development of new technology in the fields of ‘nano-materials’ and ‘nano-fluids’, it seems very promising to use this technology as a coolant in the internal c...

Speed as a crucial phenomenon of modernism affects individual and collective life of human being and changes the traits of the places people live in. Increasing speed is the demand of the modern era, though on the other side in recent years there is a contrary incline towards slowing down different aspects of life. In view of this, the dualities in between social features of Speed up and slow d...

In this paper, we consider singular and degenerate parabolic equations$$u_t =(x^alpha u_x)_x +u^m (x_0,t)v^{n} (x_0,t),quadv_t =(x^beta v_x)_x +u^q (x_0,t)v^{p} (x_0,t),$$ in $(0,a)times (0,T)$, subject to nullDirichlet boundary conditions, where $m,n, p,qge 0$, $alpha, betain [0,2)$ and $x_0in (0,a)$. The optimal classification of non-simultaneous and simultaneous blow-up solutions is determin...

the notion of $f$-derivations of up-algebras is introduced, some useful examples are discussed, and related properties are investigated. moreover, we show that the fixed set and the kernel of $f$-derivations are up-subalgebras of up-algebras,and also give examples to show that the two sets are not up-ideals of up-algebras in general.
