Abstract In order to study the effect of arrangement buried tubes on heat transfer, a three-dimensional transfer model vertical U-shaped is established. The regional thermal efficiency and soil temperature field around arranged in square array rhombic are numerically simulated. numerical simulation results compared with experimental data verify correctness established conditions. show that form...

A coil structure that is compatible with the of autonomous underwater vehicles (AUVs) and preventing rotational misalignment proposed for stabilizing output power a wireless transfer (WPT) system. The transmitting receiving are wound on energy base station AUV in spiral tube type, respectively. This arrangement not only guarantees constant mutual inductance when rotates, but it also maintains e...

Actin cables in pollen tubes serve as molecular tracks for cytoplasmic streaming and organelle movement and are formed by actin bundling factors like villins and fimbrins. However, the precise mechanisms by which actin cables are generated and maintained remain largely unknown. Fimbrins comprise a family of five members in Arabidopsis thaliana. Here, we characterized a fimbrin isoform, Arabidop...

A-Type heat exchangers are used to meet required heat load with minimum duct dimensions in air-conditioning applications. This greatly reduces the air-conditioning system footprint in residential and commercial applications. The angle and tube spacing of the A-type heat exchangers should be optimized for minimum duct size and maximum heat load. However, existing air side heat transfer and press...

Stern tube seals are a key component of the propulsion system ship. The purpose these sealing rings is to ensure reliable condition, preventing spillage lubricant environment. research on large rotary limited due their complex accessibility: stern located below seawater level moving A dynamic setup replicating operating conditions seal presented together with novel arrangement for monitoring fl...

The neglect of inertia terms and assumption of Poiseuille's flow approximations in describing the motion of a liquid with a free surface in narrow passages are inappropriate for certain motions. This is demonstrated with experiments in which the rates of spontaneous rise of a meniscus in an empty capillary tube, when one end is suddenly contacted with a pool of water, were determined with the a...

UNLABELLED Aerosol delivery of Iloprost is a promising therapeutic approach. The aim of this study was to determine the output of an ultrasonic nebulizer in different ventilation set-ups at the tip of different endotracheal tubes. METHOD In set-up A, an ultrasonic nebulizer was connected directly to the endotracheal tube. In set-up B, the nebulizer was incorporated into the inspiratory limb o...

Neural tube closure is a critical developmental event that relies on actomyosin contractility to facilitate specific processes such as apical constriction, tissue bending, and directional cell rearrangements. These complicated processes require the coordinated activities of Rho-Kinase (Rock), to regulate cytoskeletal dynamics and actomyosin contractility, and the Planar Cell Polarity (PCP) path...

More than 285 specimens of Conotheca subcurvata with three-dimensionally preserved digestive tracts were recovered from the Terreneuvian (early Cambrian) Heraultia Limestone of the northern Montagne Noire, southern France. They represent one of the oldest occurrences of such preserved guts. The newly discovered operculum of some complete specimens provides additional data allowing emendation of...
