Chitosan complex in the technology of feeding broiler chickens

The aim of the study was to study the effectiveness of using a domestic feed additive based on chitosan (chitosan complex KX-1). The three control houses had 118,000 chicks at the start of the experiment, and the three experimental houses had 117,906 chicks. Broilers of experienced poultry houses were injected with a chitosan complex at the rate of 70 g per 1 ton of compound feed during the entire growing period (38-40 days). In the control poultry houses, broilers received feed with nutritional value according to the VNITIP standards. It was found that the gross production of broilers for slaughter in live weight in three control poultry houses was 254,120 kg, in three experimental ones - 255,830 kg, and the production of poultry meat in slaughter weight - 193,950 kg and 197,957 kg, respectively. In poultry houses where the chitosan complex was used in feed for broiler chickens, 4007 kg (2.02%) more meat was obtained than in the control. This was achieved due to the higher viability and safety of broiler chickens in all experimental poultry houses - 93.14%, and in control - 91.83%. The superiority in feed conversion of broilers grown in experimental poultry houses in comparison with the control ones was established. The fat content in the pectoral and leg muscles of the control and experimental broilers was low - 1.42-1.12% and 3.84-3.42%, respectively. At the same time, in the pectoral and femoral muscles of the experimental broilers, the fat content was 0.30% (P<0.05) and 0.42% (P<0.05) less compared to the control ones, which indicates an increase in the dietary properties of meat with use of the chitosan complex in poultry feeding

Ислам и политическое развитие Синьцзяна во второй половине 1940-х годов

The article considers the national movement of the local indigenous people in Xinjiang in the second half of the 1940s and the influence of Islam on this process. The nationalimovement that involved uprisings was due to a number of complex socio-economic and political factors. In this article, the author reflects on the influence of Islam and Islamic clergy on the political processes of the region. Religion has traditionally played an important role in the lives of the indigenous peoples of the Northweof China. Sunni Islam influences the tradition of social and domestic relations, interethnic interaction and it is the ideological basis of the national struggle for liberation. The article infers that essentially the EaTurkestan Republic in Xinjiang (1945-1949) was an Islamic state. However, in the face of opposition of the Kuomintang, the CommuniParty of China and the Soviet Union, an alternative national and religious scenario in was never to be implemented.В статье рассматривается национальное движение коренных народов Синьцзяна во второй половине 1940-х годов и влияние ислама на данный процесс. Национальное движение в регионе, сопровождавшееся восстаниями, было обусловлено комплексом социально-экономических и политических факторов. В данной работе внимание автора сконцентрировано на влиянии ислама и исламского духовенства на политические процессы в регионе. Суннитский ислам оказывал влияние на традиции, социально-бытовые отношения, межэтническое взаимодействие различных народов и являлся идеологической базой национально-освободительной борьбы. В статье делается вывод о том, что по своему характеру Восточно-Туркестанская Республика, существовавшая в Синьцзяне в 1945–1949 гг., была исламским государством. Но в условиях противодействия со стороны гоминьдановского Китая, Коммунистической партии Китая и СССР, альтернатива национального и религиозного развития региона не была реализована

Spreading lengths of Hermite polynomials

The Renyi, Shannon and Fisher spreading lengths of the classical or hypergeometric orthogonal polynomials, which are quantifiers of their distribution all over the orthogonality interval, are defined and investigated. These information-theoretic measures of the associated Rakhmanov probability density, which are direct measures of the polynomial spreading in the sense of having the same units as the variable, share interesting properties: invariance under translations and reflections, linear scaling and vanishing in the limit that the variable tends towards a given definite value. The expressions of the Renyi and Fisher lengths for the Hermite polynomials are computed in terms of the polynomial degree. The combinatorial multivariable Bell polynomials, which are shown to characterize the finite power of an arbitrary polynomial, play a relevant role for the computation of these information-theoretic lengths. Indeed these polynomials allow us to design an error-free computing approach for the entropic moments (weighted L^q-norms) of Hermite polynomials and subsequently for the Renyi and Tsallis entropies, as well as for the Renyi spreading lengths. Sharp bounds for the Shannon length of these polynomials are also given by means of an information-theoretic-based optimization procedure. Moreover, it is computationally proved the existence of a linear correlation between the Shannon length (as well as the second-order Renyi length) and the standard deviation. Finally, the application to the most popular quantum-mechanical prototype system, the harmonic oscillator, is discussed and some relevant asymptotical open issues related to the entropic moments mentioned previously are posed.Comment: 16 pages, 4 figures.

Computation of the entropy of polynomials orthogonal on an interval.

We give an effective method to compute the entropy for polynomials orthogonal on a segment of the real axis that uses as input data only the coefficients of the recurrence relation satisfied by these polynomials. This algorithm is based on a series expression for the mutual energy of two probability measures naturally connected with the polynomials. The particular case of Gegenbauer polynomials is analyzed in detail. These results are applied also to the computation of the entropy of spherical harmonics, important for the study of the entropic uncertainty relations as well as the spatial complexity of physical systems in central potentials

Quantum information entropies of the eigenstates and the coherent state of the P\"oschl-Teller potential

The position and momentum space information entropies, of the ground state of the P\"oschl-Teller potential, are exactly evaluated and are found to satisfy the bound, obtained by Beckner, Bialynicki-Birula and Mycielski. These entropies for the first excited state, for different strengths of the potential well, are then numerically obtained. Interesting features of the entropy densities, owing their origin to the excited nature of the wave functions, are graphically demonstrated. We then compute the position space entropies of the coherent state of the P\"oschl-Teller potential, which is known to show revival and fractional revival. Time evolution of the coherent state reveals many interesting patterns in the space-time flow of information entropy.Comment: Revtex4, 11 pages, 11 eps figures and a tabl

Configuration Complexities of Hydrogenic Atoms

The Fisher-Shannon and Cramer-Rao information measures, and the LMC-like or shape complexity (i.e., the disequilibrium times the Shannon entropic power) of hydrogenic stationary states are investigated in both position and momentum spaces. First, it is shown that not only the Fisher information and the variance (then, the Cramer-Rao measure) but also the disequilibrium associated to the quantum-mechanical probability density can be explicitly expressed in terms of the three quantum numbers (n, l, m) of the corresponding state. Second, the three composite measures mentioned above are analytically, numerically and physically discussed for both ground and excited states. It is observed, in particular, that these configuration complexities do not depend on the nuclear charge Z. Moreover, the Fisher-Shannon measure is shown to quadratically depend on the principal quantum number n. Finally, sharp upper bounds to the Fisher-Shannon measure and the shape complexity of a general hydrogenic orbital are given in terms of the quantum numbers.Comment: 22 pages, 7 figures, accepted i

ProStor synbiotic efficiency in poultry farming

We studied the efficiency of the ProStor synbiotic for increasing the growth rate and viability of young chickens and enhancing their natural resistance, livability, and productivity during the adult stage. The homogeneity of young chickens that were reared to replace the adult ones and received the synbiotic with fodder (0.5 kg per 1 t of fodder) during 140 days of rearing was 90.3%, thereby exceeding the value of the same parameter in the control group by 3.2%. The livability of young chickens during the rearing period was 2.67% higher in the experimental group than in the control group, which caused a reduction in the fodder costs and an increase in the yield of young chickens by the time of transfer to adult livestock at the age of 20 weeks. The administration of the ProStor synbiotic in the same concentration to broiler parent stocks with 10-day courses in different biological cycles of egg laying increased the egg production per laying hen by 5.3%, hatching egg yield by 3.6%, and hatched chick yield by 2.1% in the experimental group compared with the control group. Based on the results of the study, it was concluded that the ProStor synbiotic can serve as an adequate replacement for in-feed antibiotics in poultry diets
