UWB antenna with dual notched characteristics fed by microstrip transmission line is presented in this paper. The tapered connection between the rectangular patch and the feed line is used to produce a good impedance matching from 2.3 to 11.5 GHz. A dual band frequency notches are achieved using UDGS loaded with lumped capacitors. The first notch frequency band is achieved using DGS to reduce t...

Hair cells (HCs) are mechanosensors that play crucial roles in perceiving sound, acceleration, and fluid motion. The precise architecture of the auditory epithelium and its repair after HC loss is indispensable to the function of organ of Corti (OC). In this study, we showed that Brg1 was highly expressed in auditory HCs. Specific deletion of Brg1 in postnatal HCs resulted in rapid HC degenerat...

Samverkan för Bästa Skola (SBS) avser att erbjuda ett riktat stöd till svenska skolor som har svårt förbättra verksamheten och uppfylla läroplanens mål. Studiens syfte beskriva diskutera hur nulägesanalyser åtgärdsplaner växer fram i iscensättningen av SBS på den lokala nivån. Masterplaner utgör exempel spänning existerar mellan implementera storskaliga insatser är baserade beslut-rationalitet ...

Introduction. In some solar concentrating system applications, in which the incoming sunlight is augmented by using commercial flat plate reflectors placed on different sides of planar collector, it very important to choose optimum tilts boosters (attached edge-to-edge top and bottom collector) for each month, enhance their received irradiation over year southern Algeria. The novelty proposed w...

The proposed planer layer dynamo physical model has real-world applications, especially in the Earth’s liquid core. Thus, this paper, an attempt is made to understand finite amplitude convection when there exists a coupling between Lorentz force and Coriolis force. In particular, effect of horizontally applied magnetic field studied on Rayleigh–Bénard (RBC) that contains electrically conducting...

Les montagnes françaises comptent 186 domaines skiables alpins qui ont définitivement cessé d’être exploités. Ce phénomène de fermeture débuté dans les années 1950 a particulièrement touché petits centres ski la moyenne montagne au potentiel développement limité et dont rentabilité fut mise à l’épreuve des vulnérabilités concurrentielles ou climatiques. La « détouristification » laisse planer u...

Given the well-known carcinogenicity of hardwood dust, occupational exposure to oak wood dust has been determined in a furniture factory on different processing machines during sanding, planing, and milling. Determination mass concentrations respirable inhalable from ambient air was performed using personal sampling pumps two types filter holders: Higgins-Dewell cyclone, manufactured by Casella...
