A Value

The paper summarizes results of the institutional research aimed at the determination of compressibility or values of the reduction of thickness of compressed plywood sheets. Assessing the effect of thickness and thickness tolerances of veneers to a value of compressibility in relation to production parameters was carried out on the collection of plywood whole-beech sheets of the nominal veneer thickness of 1.5 mm. The plywood sheets were manufactured as seven-ply ones and urea-formaldehyde resin DUKOL S was used for their manufacture. Following characteristics were assessed: thickness differences, size of shrinkage, compressibility of veneers. Sheets were pressed using a pressure of 1.5 and 1.7 MPa. Values of changes in the thickness of veneers in pressed veneer sheets and coefficients of compressibility of particular properties were then statistically analyzed. Basic economic evaluation was carried out of the effect of compressibility on the amount of production costs.

The 89Zr radioisotope is used in the field of tumor diagnostics, tumor therapy and the investigation of the biokinetic. The present work is investigated a suitable reaction to produce 89Zr..The Zirconium-89 excitation function via 89Y(p,n)89Zr, 89Y(d,2n)89Zr, natZr(p,pxn)89Zr, natSr(α,xn)89Zr and 90Zr(n,2n)89Zr reactions were calculated by ALICE-91 and TALYS-1.0 codes and the reaction of 89Y(p,n)89Zr has been selected. The calculated excitation function of 89Y(p,n)89Zr reaction was compared with the reported measurement and evaluations. Requisite thickness of targets was obtained by SRIM code for all above reactions except the 90Zr(n,2n)89Zr reaction. The 89Zr production yield was evaluated with attention to excitation function and stopping power for all above reactions except 90Zr(n,2n)89Zr reaction.

Butter Production

In this study, it was aimed to determine the effect of some production parameters on the characteristics of butters made from whey, which is an important dairy by-product, and creams obtained from milk. The acidity values of milk, whey, cream, and butter were respectively detected as 0.17±0.00%, 0.13±0.01%, 0.22±0.01%, 0.24±0.01%, 0.26±0.00%, 0.25±0.01%, fat values were respectively detected as; 3.50±0.14%, 0.60±0.19%, 39.0±0.34%, 43.0±0.35%, 80.0±0.46%, 84.0±0.42% and protein values were respectively detected as; 3.30±0.19%, 0.68±0.03%, 0.93±0.12%, 0.54±0.03%, 0.51±0.02%, 0.58±0.00%. 10 saturated and 7 unsaturated fatty acids were detected in cream and whey butter samples. It was seen that the most common fatty acids were palmitic, stearic, myristic and oleic acid, and the amount of oleic, stearic and linoleic acid was higher in whey butter. In conclusion, we can state that whey, which is an important dairy residue, can be used as an alternative raw material in butter production.
