The conventional ceramic route was utilized to prepare a hard magnetic powder (M-type strontium ferrite, SrFe12O19). The stoichiometric mixture of iron oxide and strontium carbonate were calcined at 1000C and then fired at various temperatures. The influence of various reaction parameters such as mixing ratio, calcination temperature, firing temperature and firing time on the magnetic behaviors...

I N A PREVIOUS PAPER,’ experiments on the application of erythrocyte powder in serologic laboratories were described. It was shown that erythrocyte powder may be successfully used for (1) absorption of useless and disturbing antibodies from test sera, (2) complement fixation test with strong group antibodies, and (3) preparation of “pure” antibodies by elution from the sensitized powder. The ai...

The Physicochemical characteristics of several kinds of toothpaste and natural powder samples and their antibacterial activity against Viridans streptococci bacteria have been studied in vitro. The Physicochemical analysis such as pH, conductivity, and moisture and fluoride concentration of the toothpaste and natural powder along with X-Ray Diffraction made in the consideration to indicating th...

The effects of microcapsulated docosahexaenoic acid powder (hereinafter DHA powder) on some viscoelastic properties of wheat flour dough and loaf volume were studied. The addition of DHA powder in the range of 0.1 to 0.3% caused a significant increase in the loaf volume of bread after baking. Dough containing 0.2 or 0.3% DHA powder had greater modulus of elasticity, viscosity coefficient and re...

introduction: in apical surgery, after apicoectomy and retro-preparation of canal, a retrofil material is applied to seal the apical region of the root canal. mineral trioxide aggregate (mta) is the gold standard material for this purpose. changing water/powder ratios of mta affects its properties. the purpose of this in vitro study was to determine the effect of liquid/powder ratio of retrofil...

The objective of this study was to determine the physicochemical and sensory properties of cooked emulsion sausages containing different levels of lotus rhizome powder (0, 1, 2, and 3%, based on total weight). Lotus rhizome powder had no significant (p>0.05) impact on pH, moisture, protein, or ash content of sausage. However, fat content was slightly but significantly (p<0.05) decreased when th...

The rehabilitation and reconstruction works are usually performed with a view to conserving these landmarks maintaining them culturally, architecturally structurally. From this perspective, the mortars utilized in repairs must be suitable, physiochemically mechanically, ancient materials used buildings. Accordingly, it was proposed evaluate tufa stone powder, waste product of one most widely fo...

Most of the pharmaceutical processes involved in the manufacturing of so lid dosage forms are connected with powder flow properties, at least for some of the intermediate steps. Powder flow characteristics are commonl y investigated by various measurements, such as handling angles, tap tes ting, shear cell measurements, etc. All these approaches allow the calc ulation of indices characterising ...
