‎Let $G=(V(G),E(G))$ be a graph‎, ‎$gamma_t(G)$. Let $ooir(G)$ be the total domination and OO-irredundance number of $G$‎, ‎respectively‎. ‎A total dominating set $S$ of $G$ is called a $textit{total perfect code}$ if every vertex in $V(G)$ is adjacent to exactly one vertex of $S$‎. ‎In this paper‎, ‎we show that if $G$ has a total perfect code‎, ‎then $gamma_t(G)=ooir(G)$‎. ‎As a consequence, ...

this study aimed to observe the protective effects of sufentanil pretreatment on rat cerebral injury during cardiopulmonary bypass (cpb) and to explore the underlying mechanism. twenty-four male adult sprague dawley (sd) rats were divided into 4 groups. then, the rat cpb model was established. a 14g trocar was inserted into the atrium dextrum. for rats in s1 and s5 groups, sufentanil (1 µg•kg-1...

due to the location of a domestic, industrial and agricultural zone near the caspian sea, this water body has long been under pressure and environmental threat. as a result of development of oil production activities in caspian region, such as oil exploration and extraction, a large volume of oil related pollutants is released annually into this important water body. considering the fact that h...

the present research proposes and optimizes the performance of a novel solar-driven combined cooling, heating, and power (cchp) kalina system for two seasons—winter and summer—based on exergy, exergo-economic, and exergo-environmental concepts applying a non-dominated sort genetic algorithm-ii (nsga-ii) technique. three criteria, i.e. daily exergy efficiency, total product cost rate, and total ...

In this study, morphometric features such as total length, standard length, and fork length obtained from a total of 321 Sparus aurata samples, including 164 females and 157 males, captured between 2012 and 2013 from İskenderun Bay were used as input value, while weight was used as an output value. The Artificial Neural Network (MLP-Multi-L Layer Perceptron) as well as the M5P algorithm and Lin...
