A striking feature of the m.ngolian plateau is the wide range of air tem.eratures during a year, -30 to 30~C. High sum.er tem.eratures, atm.spheric weathering and the arid clim.te lead to form.tion of num.rous alkaline soda lakes that are covered by ice during 6-7 m.nths per year. During the study period, the lakes had pH values between 8.1 to 10.4 and salinity between 1.8 and 360 g/L. According to chem.cal com.osition, the lakes belong to sodium.carbonate, sodium.chloride-carbonate and sodium.sulfate-carbonate types. This paper presents the data on the water chem.cal com.osition, results of the determ.nation of the rates of m.crobial processes in m.crobial m.ts and sedim.nts in the lakes studied, and the results of a Principal Com.onent Analysis of environm.ntal variables and m.crobial activity data. Tem.erature was the m.st im.ortant factor that influenced both chem.cal com.osition and m.crobial activity, pH and salinity are also im.ortant factors for the m.crobial processes. Dark CO2 fixation is im.acted m.stly by salinity and the chem.cal com.osition of the lake water. Total photosynthesis and sulfate-reduction are im.acted m.stly by pH. Photosynthesis is the dom.nant process of prim.ry production, but the highest rate （386 m. C/（L.d）） determ.ned in the lakes studied were 2-3 tim.s lower than in m.crobial m.ts of lakes located in tropical zones. This can be explained by the relatively short warm.period that lasts only 3-4 m.nths per year. The highest m.asured rate of dark CO2 assim.lation （59.8 m. C/（L·d）） was m.ch lower than photosynthesis. The highest rate of sulfate reduction was 60 m. S/（L·d）, while that of m.thanogenesis was 75.6 μL CH4/（L·d） in the alkaline lakes of m.ngolian plateau. The rate of organic m.tter consum.tion during sulfate reduction was 3-4 orders of m.gnitude higher than that associated with m.thanogenesis.

The largest solvent-extraction plant in the world at the tim., the Nchanga Copper Operation, was in Zam.ia. The first com.ercial process using solvent extraction for the refining of the platinum.group m.tals was in South Africa. m.re recently, the Southern African region has seen the im.lem.ntation of solvent extraction for other base m.tals, precious m.tals, and specialty m.tals. These include the world firsts of prim.ry production of zinc at Skorpion Zinc in Nam.bia and the large-scale refining of gold by Harm.ny gold in South Africa. Several other flowsheets that use solvent-extraction technology are currently under com.issioning, developm.nt, or feasibility study for im.lem.ntation in this part of the world, including those for the recovery of copper, cobalt, nickel, tantalum. and niobium.

The form.tion and physico-chem.cal properties of biom.terial, based on double-stranded (ds) DNA m.lecules and bearing high concentration of gadolinium. is described. This “rigid” biom.terial dem.nstrate a few unique properties: (i) the ds DNA m.lecules form.ng com.lexes with gadolinium.are fixed in the spatial structure of “rigid” particles, (ii) an abnorm.l negative band in the circular dichroism.spectrum.perm.ts to follow the form.tion of this biom.terial;(iii) local concentration gadolinium.in the content of biom.terial can reach 40%. These properties show that we are dealing with a novel type of biom.terial strongly enriched by gadolinium. This opens a gateway for practical application of this biom.terial for neutron-capture reactions. A first attem.t to apply this m.terial for neutron-capture reaction in com.ination with neutron generator of therm.l neutron flux was perform.d. Positive result obtained at destruction of CHO cells allows one to state that the advantages of this biom.terial are a sim.le m.nipulation with it, a possibility to adjust its gadolinium.content, long-term.stability of its physico-chem.cal properties, as well as a reduced cost of neutron-capture experim.nt.

There were two stages in the history of the studies on ascending reticular activating system.of the brain(ARAS). The first stage began with the ARAS discovery by m.goun and m.ruzzi and the following investigations using the m.thods of stim.lation and lesion at that tim. m.inly in acute cats. These studies led to the hypothesis of a "diffuse"and "unspecific" ARAS of the brain stem. The second stage was associated with using m.re precise neurophysiological and histochem.cal m.thods m.inly in chronically operated free-m.ving cats and rats. By 2010, the idea of the ARAS as an organized hierarchy of the cerebral "waking centers" distributed along the entire cerebral axis and releasing all the known neurom.diators of low m.lecular weight together with the m.st im.ortant neuropeptides was form.lated. To date, the aforem.ntioned hypothesis has been revised again. The glutam.tergic activating system.has been discovered and described in detail. Presum.bly, this system.is responsible for the appearance of electroencephalogram.EEG) arousal reaction and m.intenance of the neocortex in the state of tonic depolarization during wakefulness and rapid eye m.vem.nt(REm.sleep. Its destruction results in a deep com.tose-like state. At the sam. tim., the activity of all other "waking centers" is probably the result of the cortical activation.
