Engineering fatigue fracture failure is one of the most common phenomena of mechanical and structural failure, statistically representing approximately 50 to 90% of total mechanical damage [1]. Lattice structures have been widely used in crane booms, steel plants, parking garages, offshore platforms and other fields [2] to [4]. In a crane, the lattice boom has better mechanical properties compa...

Many species of birds move their heads forward through a series of successive, fixed positions when walking. This unique 'head-bobbing' behavior stabilizes visual fields during body movement, preventing motion blur of the retinal image [1–3]. Gaze stabilization could be required for successful visual search, particularly for moving objects [4], but the time available for stabilization varies wi...

Both the TATA and CCAAT boxes are widespread promoter elements and their binding proteins, TBP and NF-Y, are extremely conserved in evolution. NF-Y is composed of three subunits, NF-YA, NF-YB and NF-YC, all necessary for DNA binding. NF-YB and NF-YC contain a putative histone-like motif, a domain also present in TBP-associated factors (TAFIIs) and in the subunits of the transcriptional represso...

This paper proposes an ant colony optimization algorithm to assist railroad yard operational planning staff in their daily tasks. The proposed algorithm tries to minimize a multi-objective function that considers both fixed and variable transportation costs involved in moving railroad cars within the railroad yard area. This is accomplished by searching the best switch engine schedule for a giv...

PURPOSE The synthetic compound 3-(5'-hydroxymethyl-2'-furyl)-1-benzylindazole (YC-1) reduces the protein stability of hypoxia-inducible factor (HIF)-1α and can serve as a potential anticancer agent. Our previous study elucidated that YC-1 decreased the protein level of HIF-1α and inhibited cell proliferation under normoxic conditions. In the present study, we explored the inhibitory effect of Y...

The efficiency of container handling has got great improvement with the usage of the 40ft quay crane and the twin 40 ft yard crane. Reasonable bay planning strategies is necessary to reach the high handing efficiency by the twin 40 ft yard crane. This paper studies both bay planning and row planning for yard bay allocation. The models of bay planning and row planning are created, and the discre...

Nitric oxide (NO), the physiological activator of soluble guanylyl cyclase (sGC), induces inhibitory effects on platelet activation via elevation of cGMP levels and stimulation of the cGMP-dependent protein kinase. YC-1, a benzylindazole derivative, was shown to activate sGC in intact platelets, resulting in inhibition of platelet aggregation. In a previous study, we demonstrated that YC-1 not ...

This paper describes the development of a minimum flow algorithm to determine the number of Automated Guided Vehicles (AGVs) required at a semi-automated container terminal. At such a terminal the containers are transported by AGVs from the Quay Cranes to the Automated Stacking Cranes and vice versa. A model and a strongly polynomial time algorithm are developed to solve the case in which conta...

the present study focuses on the formation of various types of yards in mosques and the elements that contribute to the respective process. the significance of the issue lies in that certain scholars have associated the yard in mosques with the concept of garden, and have not taken into account the elements that contribute to the development of mosque yards of various types. the theoretical fin...
