Opis:
В период 247 дней откармливали 36 бычков со средним весом тела 230 кг, разделенных на 3 группы по 12 голов. Быков контрольной группы I кормили рационом со следующим составом (в % сухого вещества) : кукурузный силос 68,1%, овсяная дерть 28,8%, мочевинный препарат ЛМЗ 2,1%, минеральная смесь ММБ 1,0%. Быки опытной группы II получали такой же кормовой рацион, как и группы I, в котором, однако, 10%, а в опытной группе III 15% овсяной дерти заменено сушеной картофельной мезгой. Быки групп I, II и III показывали суточные привесы 962, 955 и 891 г. Суточные привесы быков группы III были существенно ниже (P ≤ 0,05) в сравнении с группами I и II. Потребление сухого вещества рациона на 1 кг привеса составляло: в группе I - 8,22 кг, в группе II - 7,70 кг и в группе III - 8,10 кг. Замена в рационах 10 или 15% овсяной дерти сушеной картофельной мезгой приводила к существенному (Р ≤ 0,01) снижению потребления овса на 0,83 и 1,25 кг на 1 кг привеса соответственно в группах I и III в сравнении с контрольной группой.
Thirty six young bulls with the average body weight of 230 kg were fattened for 247 days. The bulls were divided into 3 groups by 12 heads in each group. Bulls of the control group I were fed ration with the following composition (in % of d.m.: maize silage - 68.1, bruised oat grain - 28.8, urea preparation ŁMZ - 2.7, mineral mixture MMB - 1.0. The bulls of the experimental group II were fed equal ration as those of the group I, still in it 10% and in the experimental group III 15% of bruised oat grain were substituted by dried potato pulp. Daily weight gains of the group III bulls were significantly lower (P ≤ 0.05) as compared with those of bulls of the groups I and II. Intake of dry matter of the ration per 1 kg body weight gain was in group 1- 8.22, in group II - 7.72 and in group III - 8.10 kg. The substitution of 10 and 15% of bruised oat grain in the ration with dried potato pulp led to a significant decrease of the former - by 0.83 and 1.25 kg per 1 kg of weight increment correspondingly in the proups i and III as compared with the control group.

Opis:
Results of angular correlation of annihilation radiation and positron annihilation lifetime measurements are presented for atactic polystyrene and chloropolystyrenes. The inhibition of positronium formation follows the chlorine introduction as the decrease in intensities of the narrow component in angular correlation of annihilation radiation curves and of the longest-lived component in positron annihilation lifetime spectra prove. In general, the chlorine "activity" towards positrons seems to depend on its position in the polymer structure. The annihilation rate distribution as well as the radius and volume distributions of free-volume sites where positronium is assumed to be formed obtained with the use of CONTIN program for the raw sample in the 2nd series are given additionally.

Opis:
The liquid nitrogen temperature reflectivity spectra of the tetrahedral diluted magnetic semiconductors (DMS's) Zn$\text{}_{1-y}$Fe$\text{}_{y}$Se and Zn$\text{}_{1-x}$Mn$\text{}_{x}$Se crystallizing in the zinc-blende structure were investigated. The reflectivity measurements for different concentration of Fe (y = 0.01, 0.05, and 0.10) and Mn (x = 0.10 and 0.30) ions were taken out in a wide energy range between 4 and 30 eV using synchrotron radiation from ADONE storage ring in Frascati. The average resolution ΔE/E used for these measurements was better than 1 × 10$\text{}^{-3}$ over the entire spectral range. The single crystals were cleaved, before being mounted inside the reflectometer, from the samples grown by the Bridgman method. The comparison between the reflectivity spectra of ternary systems and host crystal ZnSe is made. The changes of the structures of reflectivity spectra of host crystal ZnSe caused by the influence of Fe and Mn ions are discussed.

The ternary compound valence band photoemission spectra show, in comparison to the CdSe results, two additional structures, whose intensity depends on Fe content, which were assigned to Fe 3d states of e symmetry with spin up and down, respectively. The hybridization of the t$\text{}_{2}$ component of the 3d electrons of Fe in the valence band is discussed.

Opis:
A series of liquid crystalline polyurethanes of different both flexible spacer length and mesogenic group content was studied by means of positron annihilation method. The investigated polymers were targeted on the separation of aromatic hydrocarbons from their mixtures with aliphatic ones. The effect of modification of the liquid crystalline polyurethane chain on the polyurethane free volume size and free volume distribution was determined on the basis of the positron annihilation lifetime spectra. In the positron annihilation lifetime spectra measured for the samples under study two long components of several nanoseconds, characteristic of o-Ps decaying by pick-off, occurred. The correlation of the values of the o-Ps lifetime with the size of the free volume region allowed to recover the free volume distributions with the use of the method employing the numerical Laplace inversion technique. The obtained results were compared with the diffusion data on the mobility of liquid hydrocarbons in the liquid crystalline polyurethanes enabling the correlations between polymer structure and its transport properties to be evaluated.

Opis:
Results of angular correlation of annihilation radiation and positron annihilation lifetime measurements are presented for five styrene copolymers: poly(co-styrene-phenylmaleimide) and its three derivatives with chlorine as well as for one with the OH group substituted in the benzene ring. It occurs that the chlorine substituted in three different positions in the benzene ring poly(co-styrene-o (or -m, -p)-chlorophenylmaleimide) inhibits the formation of the positronium to different extent. The greatest effect is observed in case of the chlorine atoms substituted in the benzene ring at ortho-position towards the nitrogen atom. In addition, electric dipole moments were measured for N-X-phenylmaleimide units, to check whether their magnitude influences the positron annihilation parameters. On the basis of the present results no correlation between the positron annihilation parameters and the electric dipole moments of the units was noticed.

Opis:
Recently we have been able to resolve the rare gas core contribution in long-slit angular correlation of annihilation radiation curves for some d-metals when applying a new model to fit the experimental data. In the present paper the model is applied to angular correlation of annihilation radiation spectra for the whole series of the 3d-transition metals from Sc to Cu. The model corresponds to recent theoretical predictions for the metals from the second half of the series and allows one to find the contribution of the core electrons to the whole annihilation process for these metals. Probably a different description of the angular correlation of annihilation radiation data for the metals from the beginning of the 3d-series should be searched.

Opis:
Studies of positron annihilation accompanied by EPR technique were undertaken for sodalite and lazurite and their synthetic counterparts (synthetic sodalite and ultramarines). Results of measurements performed by two techniques of positron annihilation spectroscopy (angular correlation of annihilation radiation, ACAR, and positron annihilation lifetime) revealed the undoubted influence of free radicals on positron annihilation mechanism but both inhibition of positronium formation by them and the effect of filling cages ought to be taken into account. The distinct differences between ACAR curves for sodalites, lazurites and ultramarines probably reflect the presence of different radicals in their cages and chemical heterogeneity as well as the disorder in Al, Si-site ordering in case of ultramarines. Comparison of the results of ACAR measurements with the ones of the EPR studies indicates that there is correspondence between them. Similarly to three families of the ACAR curves, different likes of EPR lines were obtained for three groups of samples; sodalites, lazurites and ultramarines. It is possible that the annihilation of positrons takes place mainly with unpaired electrons recorded by the EPR technique.
