The experiment was carried out in the lath house of Horticulture and Gardening Engineering Dept. / College Agriculture Al- Anbar University during growth season to study effect foliar spraying with chelated iron at three levels 0, 50 100 mg L-1 symbols F0, F1 F2 levels. From marine algae extract 1 1.5 g its symbol S0, S1 S2, their interaction vegetative traits leaves content mineral elements fo...

Introduction: Olivine vitrophyres are impact melts, consisting of Lunar highlands and KREEP-rich materials, that are primarily composed of olivines in an opaque glass, sometimes with lath-like plagioclase crystals [e.g. 0-2]. Petrographically, these are similar to vitrophyric Apollo 14 high-Al basalts [11]. The purpose of this study was to use olivine chemistry and petrographic evidence in orde...

Colloidal aqueous suspensions of goethite lath-shaped nanorods form nematic and isotropic phases. We show that they also display a 2D rectangular (c2mm) columnar phase at volume fractions phi larger than 15%. Interestingly, the nematic-columnar first-order transition can also be triggered by applying to the nematic phase a magnetic field of intensity decreasing with phi (1 T at 8.5%; 0.5 T at 1...

Investigations were carried out to study the effects of heat treatment on the mechanical properties of rolled medium carbon steel. The steel was heated to the austenizing temperature of 830C and water quenched; It was reheated to the ferrite – austenite two phase region at a temperature of 745C below the effective Ac3 point. The steel was then rapidly quenched in water and tempered at 480C to p...
