many studies are performed by researchers about shell and tube heat exchanger but the multi-objective big bang-big crunch algorithm (mobba) technique has never been used in such studies. this paper presents application of thermal-economic multi-objective optimization of shell and tube heat exchanger using mobba. for optimal design of a shell and tube heat exchanger, it was first thermally model...

introduction: the role of different parts of the extended amygdala in metabolic signs of stress is not well understood. in the present study, we decided to evaluate the impact of the shell part of nucleus accumbens (nac) on metabolic disturbance induced by electro foot shock stress using transient inactivation method in the rat.  methods: male wistar rats (w: 230-250 g) were canuulated unilater...

objective: prostate cancer is the second most common cancer worldwide. chemotherapeutic agents have been shown to have adverse side-effects, and natural compounds have been recommended for cancer treatment, nowadays. crab shell has been shown to have cancer preventative and suppressive effects in vivo and in vitro. the aim of present study was to investigate the effect of crab shell extract on ...

The aim of this paper is to develop a self-actualizing spirituality model. It examines the place of selfactualization in the experience of workplace spirituality of Sri Lankan business leaders. The primary method of data collection was in-depth and face-to-face interviews with 13 Sri Lankan business leaders. Within the qualitative tradition and case study method, grounded theory and data triang...

Date: __________________________________ In presenting this thesis in partial fulfillment of the requirements for a master's degree at the University ...

A new type of turtle egg fossil was established: Emydoolithus laiyangensis oogen. et oosp. nov.. Based on its elliptical morphological shape, rigid eggshells, and eggshell characteristics, it is different from other types of round chelonian egg fossils. It is the second chelonian egg fossil found in Cretaceous in China. This discovery shows the Laiyang ecosystem in Late Cretaceous is more diver...

Although several late Cretaceous sauropod colonial nesting sites have been discovered nearly on every continent during the last few decades, no studies have been performed to determine the factors that underpinned the choice of these specific sites. Here, we report the first definitive evidence of a group of sauropods that nested repetitively and purposely at a Cretaceous hydrothermal site at S...

Although the temporal overlap between human dispersal across Australia and the disappearance of its largest animals is well established, the lack of unambiguous evidence for human-megafauna interactions has led some to question a human role in megafaunal extinction. Here we show that diagnostic burn patterns on eggshell fragments of the megafaunal bird Genyornis newtoni, found at >200 sites acr...

A central question in biology is how developmental mechanisms are altered to bring about morphological evolution. Drosophilids boast a remarkable diversity in eggshell-appendage number-from as few as one to as many as nine, depending on the species. Appendage patterning in Drosophila melanogaster is well characterized, inviting candidate-gene-based approaches that identify the developmental mec...
