Recently, we researched certain twisted product CR-submanifolds in a Kaehler manifold and some inequalities of the second fundamental form of this submanifold ([11]). In this talk, we consider two kind twisted product CR-submanifolds in a locally conformal Kaehler manifold. In these submanifolds, we give a inequality of the second fundamental form (See Theorems 5.3 and 5.4) and consider the equ...

The resonance frequency, amplitude, and phase response of the first two eigenmodes of two contact-resonance atomic force microscopy (CR-AFM) configurations, which differ in the method used to excite the system (cantilever base vs sample excitation), are analyzed in this work. Similarities and differences in the observables of the cantilever dynamics, as well as the different effect of the tip-s...

Several chromite deposits located in the in the South and Southeast Arms of Sulawesi, Indonesia, have been investigated by electron microprobe. According to the variation of the Cr# = Cr/(Cr + Fe3+), the chromite composition varies from Cr-rich to Al-rich. Small platinum-group minerals (PGM), 1–10 μm in size, occur in the chromitites. The most abundant PGM is laurite, which has been found inclu...

Titanium Nitride (TiN) is a wear resistant and complementary metal oxide silicon (CMOS) compatible material that is increasingly being investigated for MEMS applications. Incorporating any new material into a MEMS device requires the development of a processing strategy. This paper discusses a wet-etching strategy for patterning and releasing TiN features on Cr sacrificial layers. Filtered arc ...

We study the behavior of contact brackets on tensor product two algebras, in particular, address question Mart\'inez and Zelmanov about extension a bracket from factors.

This study investigated the elimination of Cr(VI) from aqueous solution utilizing a composite from magnetic nanoparticles (Fe3O4) capped with cetyltrimethylammonium bromide (CTAB). The structure of the prepared composite system was examined by Fourier Transform Infra Red Spectroscopy (FTIR), X-ray Diffractometry (XRD), and Transmission Electron Microscopy (TEM). Separation of the Fe3O4/CTAB com...

Reductive adsorption of chromium (Cr) has been investigated, employing coal-based activated carbon with batchwise study. The was carried out by varying parameters such as pH the aqueous solution and contact time. Cr(III) hardly adsorbed on carbon, it precipitated at high region. High amounts Cr(VI) obtained range 4.5 – 5.5. In process, reduction to occurred especially acidic region, thus most C...

background : hexavalent chromium ( cr (vi)) is an important contaminant in surface and groundwater and its removal from contaminated water and wastewater has received interest in recent years. this study aimed to explain the removal process of cr (vi) from aqueous solution using nano hydroxyapatite (n-hap) as an adsorbent material. methods: cr (vi) removal experiments with the prepared n-hap we...

Cajal-Retzius (CR) cells play a fundamental role in the development of the mammalian cerebral cortex. They control the formation of cortical layers by regulating the migration of pyramidal cells through the release of Reelin. The function of CR cells critically depends on their regular distribution throughout the surface of the cortex, but little is known about the events controlling this pheno...
