Abstract:
Orbita medial duvarını oluşturan kemik yapılar lakrimal kemiğin lateral ya da orbital yüzü, maksiller kemiğin frontal prosesi, ethmoid kemiğin lamina papyracea’sı ve sfenoid kemiğin korpusudur. Paranazal sinüsler (PNS) çok fazla varyasyonun görüldüğü bir bölgedir. Kemik yapılar çok ince olup dehisanslar sık görülür [ONODİ 1909].
 Bu çalışmamızda standart PNS BT incelemesi yapılan hastalarda kemik devamlılığın bozulduğu vakaların sıklığını, yaş ve cinsiyet ilişkisini araştırmayı, orbita medial duvarındaki kemik defektlerin saptanması konusunda Bilgisayarlı Tomografi etkinliğinin ortaya kon

The barium titanate (BaTiO3, BT) epitaxially coated strontium titanate (SrTiO3, ST) (BT/ST) nanocube accumulation ceramics were successfully prepared by a sorbothermal method, with epitaxial interface between ST and BT, and as reference, the BT/BT nanocube accumulation ceramics were also preapred. These dielectric properties were measured for the both accumulation ceramics, and it was clearly obserbed that there was significiant difference between BT/ST and BT/BT nanocube accumulation ceramics in the dielectric properties under low and high electric fields, and the origin of the result was dis

Abstract:
Nucleation and particle growth conditions of barium titanate (BaTiO3, BT) were investigated for preparation of the BT/strontium titanate (SrTiO3, ST) multilayered nanoparticles. The conditions with and without BT nucleation were clarified. Epitaxial growth of the BT layer on the ST substrate particles was studied using both conditions. The formation of the BT layer on the ST substrate particles was confirmed using the condition with BT nucleation.

Abstract:
Barium titanate nanoparticle (BT-NP) suspensions were prepared by dispersing sol-gel-derived BT-NPs in ethylene glycol monomethyl ether (EGMME) under sonication. When an electric field was applied, a part of the BT-NPs in a suspension was deposited on the cathode by electrophoretically deposition and most of the rest of the BT-NPs settled down towards the bottom of a container. The concentration of BT-NPs in the lower part of the container (Cbottom) increased with time until the Cbottom reached a specific concentration (threshold concentration) at which sedimentation of BT-NPs start to occur.

Abstract:
Solvothermally synthesized strontium titanate (SrTiO3, ST) or barium titanate (BaTiO3, BT) nanocubes were accumulated and the dielectric properties were studied. Initially, the BT or ST nanocubes were pressed into pellets. BT was deposited on the pellets by a solvothermal method. P-E hysteresis loops and S-E curves of BT-coated ST accumulation ceramics (BT on ST) showed ferroelectric responses. The dielectric constant of the accumulation ceramics was measured to be 70.6.

The strontium titanate (SrTiO3, ST) -coated barium titanate (BaTiO3, BT) complex nanoparticles was prepared. Using this condition, ST-coated BT (ST/BT) and ST-coated ST (ST/ST) nanocube accumulation ceramics were successfully prepared with epitaxial interface between ST and BT. Dielectric properties were measured for the both accumulation ceramics, but there was no difference of the dielectric properties between both ceramics, and the origin of the result was discussed.

Hydroxyapatite (HA) and barium titanate (BT) powders were mixed and sintered to form hydroxyapatite – barium titanate (HABT) ceramics. These materials were then poled and their piezoelectric properties were measured. The microstructure of unpoled samples was examined using scanning electron microscopy (SEM).The piezoelectric constants (d33 and d31) of the ceramics were found to be dependent on the proportion of BT in the ceramic In materials containing less than 70% BT, no piezoelectric effect was found. Above this value, the piezoelectric constant increased with the addition of BT up to a val

The objective of this study was to find out the influence of curing age on microstructure in barium titanate – Portland cement composites. Barium titanate, BaTiO3 (BT) particles was mixed with Portland Cement (PC) and BT content of 50% by volume to produce the composites. All composites were cured in chamber of 60oC and 98% relative humidity for 1, 2, 3, and 7 days. Thereafter, scanning electron microscope (SEM) was used to examine the interfacial zone between cement and BT ceramics. SEM observation indicated that the BT-PC composite cured for 7 days clearly showed calcium silicate hydrate gel

Olika typer av klorfenoler (CP) användes flitigt i impregneringsmedel under 1950–70-talen i Sverige. Det var under miljonprogrammet som CP fick sin största spridning, då en miljon hushåll skulle byggas där bland annat syllarna i husen skulle vara impregnerade med CP. På 1970-talet skedde också den så kallade Teckomatorpskandalen, där företaget BT Kemi, som tillverkade en mängd olika kemiska ämnen inklusive CP, hade grävt nercirka1000 tunnor med giftiga ämnen i marken. I samband med att skandalen uppdagades förbjöds CP år 1977-1978 i Sverige, detta innefattade även produkten KP-Cuprinol som anv
