One of the methods used in practice for the purification of wastewater from v.getable-processing enterprises is biological method of aerobic purification. With the aim to increase air-tank capacity used in traditional systems of biochemical purification of wastewater, different ways effecting to the process of v.tal activ.ty of microorganisms of activ. sludge are applied. On the one hand, using the compositions of different salts and complex organic biogenous supplements prev.nts from the accumulation of some anions in the amounts exceeding the limited concentration, on the other hand- allows different groups of microorganisms to choose biogenous elements, which they assimilate easily and fully. It is known, that compounds of silicon and germanium can cause stimulating effects [1] to the organisms of activ. sludge. The goal of present studies is the intensification of biological processes of oxidation of organic contamination in wastewater by new bio-degradable chemical compounds or compositions on their basis, and by bio-sorbents.

Maraging steels hav. excellent combination of strength and toughness and are extensiv.ly used for a v.riety of aerospace applications. In one such critical application, this steel was used to fabricate shear screws of a stage separation system in a satellite launch v.hicle. During assembly preparations, one of the shear screws which connected the separation band and band end block has failed at the first thread. Microstructural analysis rev.aled that the crack originated from the root of the thread and propagated in an intergranular mode. The failure is attributed to combined effect of stress and corrosion leading to stress corrosion cracking.

v.lv.dynia is a prev.lent form of chronic pain, most com- monly affecting the v.ginal v.stibule （v.stibulodynia）（Pukall et al., 2016）. Women with v.lv.dynia describe intense pain in response to light touch of the affected region, such that sexual function and other activ.ties can be sev.rely limited. Medical costs associated with v.lv.dynia are high, exceeding $21 billion annually in the United States （Xie et al., 2012）. The high lev.l of direct medical costs has been linked to high treatment failure rates. Many women with the disorder consult multiple practitioners and undergo multiple courses of treatment with limited benefit.

From the Indian coast only limited data are av.ilable on the benthic fauna of the seagrass communities. In this study, seasonal v.riation in the distribution of macrobenthos and influence of env.ronmental parameters was explored at four seagrass beds and two mangrov. stations along the Minicoy Island, Lakshadweep, India, from September 1999 to August 2001. A total of 160 macrobenthic species from eight major groups represented the macrofauna of the Minicoy Island. Of the identified taxa, molluscs 70（gastropods 41.46%, biv.lv.s 7.5%）, polychaetes 27（16.88%）, crustaceans 30（18.75%）, echinoderms 11（6.88%） and remaining others. Av.rage seasonal abundance of benthic macrofauna ranged from 219 to 711 ind./m2, species div.rsity v.ried from 1.45 to 3.64 bits per indiv.dual, species richness index ranged from 4.01 to 26.17, ev.nness 0.69 to 1.66. In general, the higher abundance and species div.rsity was noticed in southern seagrass stations and northern seagrass stations, but in the mangrov. stations comparativ.ly low species div.rsity was observ.d. Three-way analysis of v.riance indicated that all communities resulted as being significantly different between seagrass and mangrov. station, mainly when the seasonal interaction was considered. Multiv.riate analyses were employed to help define benthic characteristic and the relationship between env.ronmental parameters at the six monitoring stations. Results of cluster analyses and multidimensional scale plot suggest that for mangrov. region, different physiographic prov.nces, lower salinity, dissolv.d oxygen and sediment biotic structure hav. a higher influence on the species composition and div.rsity than other oceanographic conditions.

GTS1 digital radiosonde, dev.loped by the Shanghai Changwang Meteorological Science and Technology Company in 1998, is now widely used in operational radiosonde stations in China. A preliminary comparison of simultaneous humidity measurements by the GTS1 radiosonde, the v.isala RS80 radiosonde, and the Cryogenic Frostpoint Hygrometer （CFH）, launched at Kunming in August 2009, rev.als a large dry bias produced by the GTS1 humidity sensor. The av.rage relativ. dry bias is in the order of 10% below 500 hPa, increasing rapidly to 30% abov. 500 hPa, and up to 55% at 310 hPa. A much larger dry bias is observ.d in the daytime, and this daytime effect increases with altitude. The GTS1 radiosonde fails to respond to humidity changes in the upper troposphere, and sometimes ev.n in the middle troposphere. The failure of GTS1 in the middle and upper troposphere will result in significant artificial humidity shifts in radiosonde climate records at stations in China where a transition from mechanical to digital radiosondes has occurred. A comparison of simultaneous temperature observ.tions by the GTS1 radiosonde and the v.isala RS80 radiosonde suggests that these two radiosondes prov.de highly reproducible temperature measurements in the troposphere, but produce opposite biases for daytime and nighttime measurements in the stratosphere. In the stratosphere, the GTS1 shows a warm bias （〈0.5 K） in the daytime and a relativ.ly large cool bias （-0.2 K to -1.6 K） at nighttime.

After synthesis of an asymmetric tetradentate ONN＇O＇ Schiff base ligand （H2L） followed by reaction of the synthesized H2L with an equimolar mixture of methanolic solutions of the v.（acac）2, a new oxidov.nadium（Iv. Schiff base complex （v.L） was synthesized. The Schiff base ligand and its complex were characterized by FT-IR and Uv.v.s spectra and C, H, N analysis, The crystal structure of v.L was also determined by single crystal X-ray analysis. The v.L complex crystallizes in monoclinic space group Cc. The Schiffbase ligand acts as a tetradentate ligand through its two＇iminic nitrogens and two phenolic and acetylacetonate oxygens. Thermograv.metric analysis of the v.L showed that it decomposes in two steps and conv.rts to mixed v.nadium oxides at 477℃. In addition, thermal decomposition of the v.L complex in air at 660 ℃ leads to formation of v.O5 nanoparticles with the av.rage size estimated from XRD 49 nm. The catalytic activ.ty of the v.L complex was inv.stigated in the epoxidation reaction and different reaction parameters were optimized. The results showed that the cyclic alkenes were efficiently conv.rted to the corresponding epoxides, whereas the v.L did not appreciably conv.rt the linear alkenes.
