Abstract During exocytosis, Golgi-derived vesicles are tethered to the target plasma membrane by a conserved octameric complex called exocyst. In contrast single gene in yeast and most animals, plants have greatly increased number of EXO70 genes their genomes, with functions very much unknown. Reverse transcription-polymerase chain reactions were performed on all 23 Arabidopsis (Arabidopsis thaliana) examine expression at organ level. Cell-level analyses using transgenic carrying...
Abstract Exocysts are highly conserved octameric complexes that play an essential role in the tethering of Golgi-derived vesicles to target membranes eukaryotic organisms. Genes encoding EXO70 subunit duplicated plants. Based on expression analyses, we proposed previously individual members may provide exocyst with functional specificity regulate cell type– or cargo-specific exocytosis, although direct evidence is not available. Here, show that, as a gene expressed primarily during tracheary...
Enhancing the capabilities of unmanned space exploration, such as satellite monitoring and science missions, requires efficient reliable nuclear power systems. A viable solution is found in 1∼10 kWe level reactor systems, offering advantages a manageable research development process, relatively low investment requirements. This paper introduces conceptual design for 5 system, outlining its components characteristics. The study includes thorough analysis potential challenges, encompassing...
Early embryogenesis is the most fundamental developmental process in biology. Screening of ethyl methanesulfonate (EMS)-mutagenized populations Arabidopsis thaliana led to identification a zygote-lethal mutant embryonic factor 19 (fac19) which embryo development was arrested at elongated zygote octant stage. The number endosperm nuclei decreased significantly fac19 embryos. Genetic analysis showed caused by single recessive mutation with typical mendelian segregation, suggesting equal...
A high-frequency sheet-beam klystron operating at a low perveance per square can produce high peak power efficiency. In order to provide beam stability and maximize extraction efficiency for flat with finite width, we have designed RF cavities in which the electric field is nearly constant across width of (on several wavelengths). However, such cavities, fundamental mode couple TE propagating drift section if any cavity or asymmetry present. The dipole between adjacent even absence these...
An experimental study of post-dryout heat transfer with the coolant R-134a was performed in a vertical round tube upward flow. The experiments were conducted an uniformly heated inside diameter 10 mm and length 3100 mm, at pressures 11.1 bar, 16 bar 28 varying mass flux range 300–1500 kg/m2s. results show that for higher fluxes wall temperature decreases after reaching peak close to critical vapor quality, while lower keeps increasing dryout. phenomenon described last is shifted even rising...
The structural design of vehicles plays an important role in improving vehicle safety and driving performance. In this study, the frame structure a van-type electric truck was taken as research object. Stress, strain, modal analyses were performed using Abaqus, finite element software, to verify rationality design. optimized by numerical analysis. fourth beam moved 524 mm forward between installation points power battery pack rear lifting lug front leaf spring. Results showed that bending,...
Abstract Post dryout heat transfer and rewetting are important processes determining the level time duration of high temperature phase integrity fuel cladding. In spite extensive studies in past decades, reliable prediction methods still missing due to complexity involved, which consist mainly interaction between solid wall, main gas flow droplets. present study, a phenomenological model is proposed considering three individual parts. Main new features compared models available open...
.A lead-based reactor with employing heat pipes as passive residual removal system (PRHRS) for longterm decay was designed. Three-dimensional computational fluid dynamics (CFD) software FLUENT adopted to simulate the thermal-hydraulic characteristics of PRHRS under Station-Black-Out (SBO) accident condition. The results showed that in core could be removed smoothly by PRHRS, and temperature difference is less than 20 K.
A ceramic based power extractor operating at 21 GHz was built by DULY Research Inc. and tested CTF2, the CERN Linear Collider (CLIC) Test Facility. The structure includes a section, 2-output-port, circular-to-rectangular waveguide coupler, 3-port rectangular combiner that provides for single output waveguide. Results of cold tests full beam are presented compared with theoretical numerical models.
Rod-loaded structures were studied for multi-beam and single-beam metal cavities. Coupling efficiency, parasitic modes their dependence on inter-beam spacing a 6-beam, high-power, X-band MBK included in this study. Realization of Photonic Band Gap (PBG) effect klystrons was also considered.
