Apple/Malus x domestica cv. ＇Topaz＇/M26 and sour cherry cv. ＇Debreceni Botermo＇/Prunus mahaleb L. maidens were fertilized with different organic fertilizers and soil amendments in an organic nursery. A mycorrhizal inoculant, Micosat, was added to the non-fertilized control and to combinations fertilized with various bioproducts. Under assessment was the effect of nutrient delivery on the growth and development of maiden fruit trees focussing on tree height, thickness of the tree trunk, the number and the length of lateral shoots in each treatment combination. It was found that the introduction of mycorrhizal fungi into the soil without fertilizer application significantly improved the growth and development of apple and sour cherry maidens. Mineral fertilizer application （NPK） combined with mycorrhizal inoculation had a negligible effect on the above features. In the presence of bioproducts such as granular manure, Humus Active ＋ Aktywit PM, BF Amin, Vinassa and Florovit Eko, the mycorrhizal fungi were more biologically active than in the absence of these products.

Wheat gliadin proteins-an important, nutritional component of many food products may also act as allergenic proteins causing various, clinical symptoms of IgE-mediated food allergies. Gliadins are coded by six complex loci on the chromosomes 1A, 1B, 1D,6A, 6B and 6D of wheat genome. Each of the loci coding from a few to a dozen of polypeptides may spontaneously mutate to inactive gene variants called null alleles that do not code any proteins at all. The aim of the present work was to find out whether null alleles in some gliadin coding loci may decrease wheat allergenic properties. Six winter wheat genotypes: gliadin deletion lines (GDL) containing null alleles on 1D, 1B and 6B chromosomes and control lines (CL) containing active gene variants in all gliadin coding loci, were developed using plant breeding methods. Allergenic properties of the six analyzed hybrids were estimated by ELISA using polled sera of five patients allergic to gluten. Estimated immunoreactivity of GDLs was from 6% to 18% lower as compared with CLs. The obtained results evidenced that gliadin null alleles decrease wheat allergenic properties and may be used as parental forms for breeding of hypoallergenic wheat genotypes.

Basing on the experimental results of the hardenability investigations, which employed Jominy method, the model of the neural networks was developed and fully verified experimentally. The model makes it possible to obtain Jominy hardenability curves basing on the steel chemical composition. The modified hardenability curves calculation method is presented in the paper, initially developed by Tartaglia, Eldis, and Geissler, later extended by T. Inoue. The method makes use of the similarity of the Jominy curve to the hyperbolic secant function. The empirical formulae proposed by the authors make calculation of the hardenability curve possible basing on the chemical composition of the steel. However, regression coefficients characteristic for the particular steel grade must be known. Replacing some formulae by the neural network models is proposed in the paper.

首先给出赋范线性空间中的非空集合C的逼近紧性的等价描述.如所周知,如果C是Banach空间X中的一个逼近紧的半Chebyshev闭集,那么由X到C的度量投影算子π_c是连续的.当X是中点局部一致凸的Banach空间,利用Banach空间几何的技巧证得:C的逼近紧性对投影算子π_c的连续性也是必要的.利用这个一般结论给出:当T是由逼近紧且严格凸的Banach空间X到中点局部一致凸Banach空间Y的有界线性算子时,T有连续的Morse-Penrose度量广义逆T^+的充分必要条件.

Advances in Alzheimer's Disease 2013年第1期2卷 1-6页

Alzheimer’s disease (AD) is accompanied by elevated levels of homocysteine (Hcy). Homocysteine may induce elevated concentration of asymmetric dimethylarginine (ADMA). Both Hcy and ADMA are the amino acids thought to represent risk factors of vascular diseases. Studies were conducted on the plasma levels of Hcy and methionine (Met), estimated by HPLC with electrochemical detection, as well as on levels of ADMA and arginine (Arg), estimated by HPLC with fluorescent detection, in the AD patients with benign through to severe dementia estimated by MMSE scale and in a control group. The studies disclosed elevated levels of Hcy and ADMA in AD (Hcy, p < 0.001) as compared to controls, as well as in subjects older than 60 years of age (Hcy, p < 0.01). The AD patients with severe dementia have shown elevated levels of Hcy (p < 0.05) as compared to the patients with moderate dementia. The concentration of Metand Arg showed a downward trend in AD patientswith severe dementia. The highest levels of ADMA have been demonstrated in AD patients in the early stages of the disease. In parallel, in AD with varying degrees of dementia and subjects older than 60 years of age a disturbed turnover was observed of Hcy to Met and of Arg to ADMA. Similarly to Hcy, ADMA seems to be a potential risk factor of AD and important factor for progress of dementia.
