For safe development of underground space and especially in areas of geological infringements it is necessary to creat effective system of tracking, forecasting and management for deforming processes in such areas-system of geomechanical monitoring. Besides it is necessary to study and imagine the internal mechanism of deforming processes in such special zones. In the paper some basic aspects of creation of geomechanical monitoring systems for realization of supervision, study and modelling of deforming processes, for modelling and study of the stress-strain state of massif in areas of large-scale underground mining works in view of a block-hierarchical structure of rock’s massive (presence of geological infringements) are considered. In particular such important tasks, as research of deforming processes in areas of geological infringements with the help of GPs-technologies and use of the received results for the modeling; construction of models adequately describing a condition of rock’s massive in area of geological infringement. some results of researches on study of cavities influence on occurrence of an area of limiting conditions in region of geological infringement and possible shift along infringement are submitted.

This work is concerned with applying the fractional calculus approach to the magnetohydrodynamic （mHD） pipe flow of a fractional generalized Burgers＇ fluid in a porous space by using modified Darcy＇s relationship. The fluid is electrically conducting in the presence of a constant applied magnetic field in the transverse direction. Exact solution for the velocity distribution is developed with the help of Fourier transform for fractional calculus. The solutions for a Navier-stokes, second grade, maxwell, Oldroyd-B and Burgers＇ fluids appear as the limiting cases of the present analysis.

In humans, specific patterns of killer immunoglobulin-like receptors （KIRs） expressed by uterine natural killer （uNK） cells are linked through HLA-C with pregnancy complications （infertility, recurrent spontaneous abortion, intrauterine growth restriction and preeclampsia）. To identify mechanisms underpinning the associations between NK cell activation and pregnancy success, pregnancies were studied in mice with genetic knockdown （KD） of the mHC-activated Ly49 receptor gene family. ***49KD pregnancies were compared to normal control ***49z29 and C57BL/6 （B6） pregnancies. At mid-pregnancy （gestation day （gd9.5））, overall uNK cell （TCRI^-CD122＋DBA＋DX5- （DBA＋DX5-）） and TCRIβ-CD122＋DBA-DX5＋（DBA-DX5＋）） frequencies in pregnant uterus were similar between genotypes. Ly49KD lowered the normal frequencies of Ly49＋ uNK cells from 90.3% to 47.8% in DBA-DX5＋ and 78.8% to 6.3% in DBA＋DX5- uNK cell subtypes. ***49KD matings frequently resulted in expanded blastocysts that did not implant （subfertility）. ***49KD mice that established pregnancy had gestational lengths and litter sizes similar to controls. ***49KD neonates, however, were heavier than controls. ***49KD implantation sites lagged in early （gd6.5） decidual angiogenesis and were deficient in mid-pregnancy （gd 10.5） spiral arterial remodelling. Ultrastructural analyses revealed that ***49KD uNK cells had impaired granulogenesis, while immunocytochemistry revealed deficient vascular endothelial cell growth factor （VEGFA） production. Perforin and IFNG expression were normal in ***49KD uNK cells. Thus, in normal mouse pregnancies, Ly49 receptor signaling must promote implantation, early decidual angiogenesis and mid-pregnancy vascular remodelling. Disturbances in these functions may underlie the reported genetic associations between human pregnancy complications and the inability of specific conceptus mHCs to engage activating KIR on uNK cells.

Armillaria sp. F022, a white rot fungus isolated from tropical rain forest （samarinda, Indonesia） was used to biodegrade naphthalene in cultured medium. Transformation of naphthalene by Armillaria sp. F022 which is able to use naphthalene, a two ring-polycyclic aromatic hydrocarbon （PAH） as a source of carbon and energy was investigated. The metabolic pathway was elucidated by identifying metabolites, biotransformation studies and monitoring enzyme activities in cell-free extracts. The identification of metabolites suggests that Armillaria sp. F022 initiates its attack on naphthalene by dioxygenation at its C-1 and C-4 positions to give 1,4-naphthoquinone. The intermediate 2-hydroxybenzaldebyde and salicylic acid, and the characteristic of the meta-cleavage of the resulting diol were identified in the long-term incubation. A part from typical metabolites of naphthalene degradation known from mesophiles, benzoic acid was identified as the next intermediate for the naphthalene pathway of this Armillaria sp. F022. Neither phthalic acid, catechol and cis, cis-muconic acid metabolites were detected in culture extracts. several enzymes （manganese peroxidase, lignin peroxidase, laccase, 1,2-dioxygenase and 2,3-dioxygenase） produced by ArmiUaria sp. F022 were detected during the incubation.

＜正＞ The present study was stimulated by the problem of onion seed production in Bangladesh and similar regions where seed production is possible only during the short cool winter period after which rapid increase in temperature as well as early shower adversely affect the quality of seed. Experiments were carried out in order to develop suitable production techniques to get high yield and quality of onion seed overcoming the stated adverse situation.

Brewer’s spent grain (BsG) is a large-scale agroindustrial waste that could be more efficiently utilized. This waste is composed of lignocellulosic material and so may serve as a good source of biomass for thermochemical conversion. The present study investigated the fluid dynamics behavior of mixtures of sand and BsG in a spouted bed to assess the viability of the thermochemical conversion of this biomass via fast pyrolysis. Fluid dynamics analyses were performed while varying the mass fraction of BsG (6–80%) and the static bed height (6.6–13.4 cm). Empirical equations for predicting the minimum spouting conditions and the mixing index were obtained using a regression technique, and the selected fluid dynamics parameters were employed in the spouted bed pyrolysis. The bio-oil resulting from this process was rich in phenolic compounds, various nitrogenated compounds (representing precursors for pharmaceuticals) and long-chain hydrocarbons. The products obtained from the analytical and spouted bed pyrolysis processes were also compared.
