Measured and calculated steady aerodynamic loads on a large-scale upper-surface blown model [PDF]

open access: yes
Static aerodynamic loads measurements from wind tunnel tests of a full-scale upper surface blown jet flap configuration are presented. The measured loads are compared with calculations using a method for predicting longitudinal aerodynamic ...

Modelling of firm offer from combined wind and hydro generations [PDF]

open access: yes, 2019
This paper analyses the impact of a firm combined offer by wind and small hydro generators located in the river chain, with a view to address the intermittency of wind generators.

Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

open access: yesFEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

Flight-Measured Aerodynamic Loads on a 0.92 Aspect Ratio Lifting Surface [PDF]

open access: yes
Ventral fin loads, expressed as normal force coefficients, bending moment coefficients, and torque coefficients, were measured during flight tests of a YF-12A airplane.

Profiling the effect of low frequency mechanical vibration on the metabolic and oxidative stress responses of A431 carcinoma

open access: yesFEBS Open Bio, EarlyView.
20 Hz mechanical vibration induced A431 cancer cells' apoptosis without such effect on other healthy cell lines of L929 and C2C12. Lowered glucose consumption is observed specifically in A431. The expressions of ROS, HMGB1, and HSP1 levels initially increase and subsequently decrease in the cancer cell line, as opposed to L929 and C2C12, which ...

Problems on Wind Load Measurements

open access: yesWind Engineers, JAWE, 1986
The problems of the wind pressure measurements can beattributed to little knowledge of the characteristics of the actual wind pressures. The difference to a ordinal wind tunnel test arises mainly from the discrepancy of Reynolds number and the unsteadiness in anaturalwind flow.On the point ofwily the example of themeasuredpressure data of a hotel ...

Rolling maneuver load alleviation using active controls [PDF]

open access: yes
Rolling Maneuver Load Alleviation (RMLA) was demonstrated on the Active Flexible Wing (AFW) wind tunnel model in the LaRC Transonic Dynamics Tunnel. The design objective was to develop a systematic approach for developing active control laws to alleviate

Construction of hyperthermostable d‐allulose 3‐epimerase from Arthrobacter globiformis M30 using the sequence information from Arthrobacter psychrolactophilus

open access: yesFEBS Open Bio, EarlyView.
d‐Allulose can be produced from d‐fructose by d‐allulose 3‐epimerase. Based on sequence homology information, we successfully engineered thermostable mutants with the protein engineering method. By integrating positive mutations, we constructed an enzyme that exhibits hyperthermostability without a loss in the activity.

Natural environment analysis [PDF]

open access: yes
Qualitative analyses (and quantitatively to the extend possible) of the influence of terrain features on wind loading of the space shuttle while on the launch pad, or during early liftoff, are presented.
