A compressible air permeability model is developed to simulate the aerodynamic performance of the supersonic porous canopy.And a single-degree-of-freedom model is applied to analyse the static stability of the parachute.By using this Hay Bag Feeder PVC Mesh method, the flow structure of the parachute system with big attack angle is obtained.The aer
The paper features the problem of the interpersonal relations of the civil servants with the different level of social normativity.Harmony / disharmony of the interpersonal relations caused by a social and psychological distance between the interacting subjects prove to be the indicators of personnel risk for the organization.A change of a distance
Materials capable of circularly polarized luminescence (CPL) have attracted considerable attention for their promising potential applications.Bacterial cellulose (BC) was characterized as having a stable right-handed twist, Ultrasound - Ultrasound Probe Covers which makes it a potential chiral host to endow luminophores with CPL.Then, the CPL-activ
Root growth and crop yield can be affected Loafer Shoes by chemical modifications of the soil profile owing to lime and gypsum applications.A field trial was carried out on a dystrophic Clayey Rhodic Hapludox at Ponta Grossa, PR, Brazil, aiming to evaluate lime (without or with incorporation into the soil) and gypsum effects on root growth, mineral
