free-field‚ one encounters several complicating effects: Instead of plane waves at normal incidence and constant intensity along the propagation path‚ we have oblique incidence‚ spatial energy spreading‚ interaction of different sound sources‚ and diffraction waves emerging from impedance discontinuities on the walls.

the quartz-type FePO4 at elevated temperatures and during the occurrence of the α- β transition stage. The temperature range that was selected for the investigation was from 294K to 1073K and the investigation was carried out by neutron powder diffraction. The properties of the quartz-type FePO4 was compared to other α-quartz homeotypes such as SiO2 and AlPO4‚ and it was discovered that the quartz-type FePO4 behaves in a markedly different manner from SiO2 and AlPO4 in the α- phase.

Bahariya Bahariya oasis is a natural oval shaped depression. It is located at the contact between cretaceous and Eocene deposits. One of the early geologic works was carried out by Ball and Beadnell (1903). They produce a topographical- geological map of the oasis and discuss the stratigraphy of the rock exposed. They distinguished three topographic features; the bounding escarpments; the conical hills within the depression and the oasis floor. They notice that the southern scarp is steeper than

In this work‚ the Fe3O4 NPs were synthesized by a co-precipitation method. The prepared Fe3O4 particles were dispersed well in water and stay stable for several days. FT-IR spectra of Fe3O4‚ mercaptosuccinic acid and mercaptosuccinic acid functionalized Fe3O4 are shown in Figure 1(a-c)‚ respectively. In Figure 1a‚ the sharp band at about 585 cm-1 corresponds to the characteristic Fe–O vibration peak and the bands at around 3420 cm-1 are due to the stretching vibrations of the hydroxyls (–OH) on the

The increased affinity towards complex formation exhibited by metal ions with an unfilled d-shell is related to the crystal field stabilization of such compounds and furnishes an

WIRELESS POWER TRANSMISSION Abstract: We are implementing new concept in our project. We are going to transmit the electrical energy without wire. It is not easy concept. Here power is transmit from one place to another place using electromagnetic induction or laser concept. Wireless energy transfer or Wireless power is the transmission of electrical energy from a power source to an electrical load without interconnecting wires. Wireless transmission is useful in cases where interconnecting
