It is unfortunately not too rare to find that fire investigators estimate flame temperatures by looking up a handbook value,
which turns out to be the adiabatic flame temperature. Generally, the measurement of temperature in an industrial furnace
is difficult, time consuming and expensive. Combustion of bagasse has its own special set of problems which appear to be due
largely to the high moisture content and varying particle sizes of the fuel. The present experimental investigation is carried
out to estimate the location of reaction zones and temperature fields in a bagasse fired furnace. Furnace is modeled by three
dimensional CFD codes. Both experimental and the computational results show a considerable delay to ignition due to the drying
of fuel. Also the location of maximum temperature zones and the pattern of flame propagation inside the furnace are clearly

The validity of the Poisson and theP(k) modified Poisson statistical density functions of observing k events in a short time interval t=T/n, proposed previously by others, is investigated experimentally in radioactive decay detection for various measuring times, T. The experiments to measure radioactive decay were performed with 89my (T1/2=16.06 s), using a multichannel analyzer operating in the multiscaling mode. According to the results, Poisson statistics adequately describes the counting experiment for short measuring times (up to T<0.5 T1/2) and its application is recommended. However, analysis of the data demonstrated, with confidence, that for long measurements (T>1 T1/2) Poisson distribution is not valid and the modified Poisson function is preferable.

At room-temperature and atmospheric pressure, using electrode disks of various sizes, under the action 4 7Vdc eletric field, we gettered tritium gas from 2.2L of air containing (0.15 18.61)×108 Bq of tritium and (3000 12000) ppm of moisture during 50 hours or so the efficiency of gettering tritium was over 95%. Applying liquid scintillation counting method, we measured the tritium in the disks after gettering, and found that the amounts of tritium in the disks were equal to those reduced in the tested tritiated air.

The magnesium-cerium system has been partially revised in the Ce-rich and Mg-rich regions by using results obtained with the
Smith thermal analysis (STA) technique. Nine alloys were examined and, after the thermal measurements,were subjected to phase
analysis by means of X-ray powder diffraction (XRD), optical(LOM) and scanning electron microscopy (SEM), and electron probe
microanalysis (EPMA).The coordinates of the invariant reactions, many of them very close to each other, were established and
compared with literature data where a call for a deeper investigation was proposed as the thermal values were open to different
This paper investigates the simultaneous reduction and oxidation reactions of uranium in hydrochloric acid media. The redox reactions were carried out in a cell fitted with a cation exchange membrane and hexavalent uranium was reduced to the tetravalent state in the cathode chamber. The reverse reaction was carried out in the anode side of the cell. The reaction rate was found to be independent of the uranium concentration and the extent of reaction was linear with time. There is evidence of uranium flux across the membrane.
In this study, radiocesium sorption on ceramic clay was investigated as a function of particle size and initial 137Cs concentration using a batch method. Ceramic clay samples taken from the Söğüt(İnisar) clay deposit were composed of kaolinite,
dickite and quartz. The equilibrium time and the liquid–solid ratio were determined as 60 min and 250 mL g−1, respectively. The distribution coefficients (Kd) for variable liquid–solid ratio and the percentage adsorption (PAd) were calculated. The values of Kd and PAd ranged from 483 to 3165 mL g−1 and 34–93%, respectively. The Kd and PAd values increased with increasing particle size, but decreased with increasing initial concentration. The sorption data were
interpreted in terms of a Langmuir isotherm. The results indicated that the Söğüt(İnhisar) ceramic clay has good sorption
capacity for cesium.
