JJEE BB CC llaa ssss iicc ss JEB Classics is an occasional column, featuring historic publications from The Journal of Experimental Biology. These articles, written by modern experts in the field, discuss each classic paper’s impact on the field of biology and their own work. A PDF of the original paper accompanies each article, and can be found on the journal’s website as supplemental data. A ...

A desire to further comprehend the hydrodynamic characteristics of three-dimensional undulating fin propulsion is what motivates work. First, a high-resolution numerical technique based on constraint immersed boundary method utilized simulate fluid-fin system. The simulation results reveal fundamental variation laws between performance and kinematic parameters. According data, an in-depth analy...

in coastal areas, hydrodynamic factors make changes in shorelines geomorphology. this can affect coastal facilities and cause hazards to human societies in the areas. this study has investigated the influence of wave and tide properties on khamir port, hormoz strait in coast of persian gulf. the purpose of the study is to make a mathematical regional and local modeling of water level fluctuatio...

New 2-phenylpyridazinones, analogs o f 4-chloro-5-methylamino-2-phenylpyridazin-3(2H)ones, were assayed for their phytotoxic activity to interfere with plant pigment formation. Six derivatives with — SCF3, — OCF2CH FCF3, — O CH F2, — CN, or — Br in meta position o f the phenyl ring exhibited similar or better bleaching activity than the m -CF3 analog (norflurazon). The activity is predominantly...

Evidence in support of safety of a gene delivery procedure is essential toward gene therapy. Previous studies using the hydrodynamics-based procedure primarily focus on gene delivery efficiency or gene function analysis in mice. The current study focuses on an assessment of the safety of computer-controlled and liver-targeted hydrodynamic gene delivery in dogs as the first step toward hydrodyna...

The mystacial vibrissae of harbour seals (Phoca vitulina) constitute a highly sensitive hydrodynamic receptor system enabling the seals to detect and follow hydrodynamic trails. In the wild, hydrodynamic trails, as generated by swimming fish, consist of cyclic burst-and-glide phases, associated with various differences in the physical parameters of the trail. Here, we investigated the impact of...
