Yarı ince kesitlerin kullanımı histolojik ve klinik tanı çalışmalarında önemli bir yere sahiptir. Fakat bu amaçla kullanılan plastik gömme ortamları hidrofobik oldukları için boyaların dokulara girişini sınırlandırmaktadırlar. Bu çalışmada; yarı epon boyanmasında daha çok detay sağlamak üzere bilinen solventleri ile asetonun karşılaştırılması önce denenmemiş toluidine blue-eozin ikili boyamasın...

Fly ash merupakan limbah hasil pembakaran pabrik kelapa sawit yang mengandung silika dan mineral alkali dikenal sebagai komponen penting adsorben. Dolomit diketahui juga material sedimentasi karbonat memiliki kemampuan menyerap logam. Bahan baku utama digunakan untuk penelitian adalah fly diperoleh dari Pabrik Kelapa Sawit Mutiara Agam di Provinsi Sumatera Barat, dolomit Kamang, methylene blue ...

Soil salt-alkalization is a major limiting factor for crop production in many regions. Switchgrass (Panicum virgatum L.) is a warm-season C4 perennial rhizomatous bunchgrass and a target lignocellulosic biofuel species. The objective of this study was to evaluate relative alkali-salt tolerance among 30 switchgrass lines. Tillers of each switchgrass line were transplanted into pots filled with f...

tetrachloride in T H F produces blue-green crystals that are stable to water and to aqueous acid or alkali. The compound can be sublimed or recrystallized from benzene or toluene. The compound is pyrophoric but controlled air oxidation yields uranium oxides and cyclooctatetraene. Mass spectral analysis gives a parent peak for U(CeH& and the fragmentation pattern indicates a ferrocene-like sandw...

Vibrational spectra of BH(4)(-) and its isotopic analogues in a crystalline environment of alkali metals cations (K(+), Rb(+), Cs(+)) have been investigated beyond the harmonic approximation using a variational approach supported by computations of B3LYP type anharmonic force fields. From the comparison of the observed and simulated IR spectra, the influence of the anharmonic couplings on the b...

We found a method for controlling the elution property of a thin film of water-dispersible Prussian blue (w-PB) nanoparticles using a simple electrochemical treatment. The thin film of the w-PB nanoparticles fabricated by the spin-coating method was unstable in water and eluted easily. However, after electrochemical reduction and oxidation, the film did not elute in water. To clarify the mechan...

Physicochemical properties of surimi and kamaboko obtained of solubility in acid, alkaline and conventional methods were compared. The results indicated that the highest protein recovery was related to solubility in acid, alkaline and conventional methods, respectively. The highest removal of lipid and myoglobin was observed by solubility in alkali. Excretion of total pigment and sulfhydryl gro...

the properties of alkaline sulfite anthraquinone (as/aq) pulp from old corrugated container (occ)was studied. in each trial 100 grams (based on dry weigth) of occ and 18% active alkali was used.three levels of anthraquinone (0.0.1 and 0.2% based on dry weigth of the occ) and two pulpingtimes (120 and 150 minutes at maximum pulping temperature) were applied. pulping temperature,na2so3/naoh ratio...
