Two experiments tested a bottlenosed dolphin’s ability to match objects across echolocation and vision. Matching was tested from echolocation sample to visual alternatives (E–V) and from visual sample to echolocation alternatives (V–E). In Experiment 1, the dolphin chose a match from among three-alternative objects that differed in overall (global) shape, but shared several ‘local’ features wit...

PURPOSE To elucidate the proteins required for specialized small interlocking protrusions and large paddle domains at lens fiber cell tricellular junctions (vertices), we developed a novel method to immunostain single lens fibers and studied changes in cell morphology due to loss of tropomodulin 1 (Tmod1), an F-actin pointed end-capping protein. METHODS We investigated F-actin and F-actin-bin...

In order to improve their long-term viability, wave energy converters (WECs) need be able shed loads when a threshold condition is exceeded. As shown by Tom et al. (2016) [1], provision of adjustable flaps within the body an oscillating surge converter (OSWEC) allows pass through device. A control system may then open and close waves approaching device exceed preset thresholds. The variable-geo...

This paper focuses on mixing strategies and designing shape of the bottom topographies to enhance growth microalgae in raceway ponds. A physical-biological coupled model is used describe algae. simple a device such as paddle wheel also considered. The complete process was then included an optimization problem associated with maximization biomass production. results show that non-trivial can be ...

The paper is focused on analysis, mathematical modelling and simulation of reactors which are used in the chemical and tanning technology. Material and energy balances are the key issues of mathematical models of chemical reactors and processes. The combination with chemical kinetics and transport effects an intellectual basis for chemical reactor design can be obtained. The contribution brings...

The synthesis of an NbO-type metal-organic framework was achieved by design: o-Br-BDC (BDC = benzenedicarboxylate) was used to direct the formation of Cu2(CO2)4 paddle wheel units at 90 degrees to each other and thus yield the target network. The compound was formulated as Cu2[o-Br-BDC]2(H2O)2.(DMF)8(H2O)2 (MOF-101) and characterized by single-crystal X-ray diffraction [cubic, space group Imm (...

The advantage of using paddle dryers (PD) in the production of sugars and 2nd generation ethanol from pretreated wheat straw was investigated. This machinery was employed in order to detoxify steam-exploded substrates and to mix different slurries in the hydrolysis step. The obtained hydrolysate was fermented by the yeast Saccharomyces cerevisiae. Acetic acid and furfural were reduced up to 11 ...

This work concerns the numerical generation of stable solitary waves by using a piston-type wave maker and propagation characteristics in step-type flume. The was performed solving N-S (Navier–Stokes) equations on open source CFD (computational fluid dynamics) platform OpenFOAM. To this end, new module dynamic boundary conditions programmed can be applied to prescribe horizontal linear motion p...

Semaphore, a way of communicating remotely, usually practiced in scouting activities. Information is delivered by gestures or movements using specific tools such as flags, paddles or rods. Teacher and instructors are needed for learning semaphore in conventional way as they will give examples and make correction when such an error occured. Based on the practical need to provide an alternative w...
