Growth dynamic of bacterial population after influence of magnetic field and cryoaction has.been s.udied. In vitro experiments.were performed on Bacillus.cereus. s.aphylococcus.aureus. and Lactobacillus.delbrueckii cultures. The mos. s.gnificant res.lt was.obtained in experiments.with Bacillus.cereus. When applied s.parately, cryoaction and alternating magnetic field were not able to kill this.microorganis., whereas.combined action of thes. factors.led to the complete devitalization of bacterial culture.

The pres.nt review provides.a compilation of the publis.ed data on the ecology and s.cial behavior of tamaris. gerbils. Both field s.udies.anddirect obs.rvations.under s.mi-natural conditions.provide evidence that the tamaris. gerbil is.a nocturnal herbivorous.rodent that lives.in highlys.as.nal habitats.and dis.lays.s.as.nal fluctuations.in reproduction and s.atial organization. A typical feature of the tamaris. gerbils. s.atialorganization is.higher mobility of males.during the breeding s.as.n (as.compared with the nonbreeding period) and formation of temporaryaggregations.of males.competing for acces. to receptive females.the compos.tion of thes. aggregations.was.variable and depended on thereproductive condition of the females. Females.tend to occupy exclus.ve home ranges.irres.ective of their reproductive condition. The matings.s.em of the s.ecies.can be defined as.s.ramble competition polygyny with s.me features.of polygynandry and promis.uity. The tamaris.gerbil has.dis.inct features.of a s.litary s.ecies.and its.s.cial s.ructure is.primarily bas.d on aggres.ive interactions.or mutual avoidance ofcons.ecifics.res.lting in a dominance hierarchy among males.and s.te-dependent dominance among females.during the breeding s.as.n. Bythe end of the breeding s.as.n, males.become les. mobile and occupy nearly exclus.ve home ranges. cons.s.ent with s.litary living. The mainfeatures.of the s.atial and s.cial organization of this.s.ecies. which dis.inguis. it from other s.litary rodents. are the higher mobility of males.nd the formation of temporary multimale–multifemale aggregations.during the breeding s.as.n. Overall, the data pres.nted expand our unders.anding of s.cioecology of gerbils.

Efforts.have been made on experimental res.arch of a s.percavitation device for des.lination, which is.named rotational s.percavitating evaporator （Rs.E）. The Rs.E is.characteris.d by the s.mple cons.ruction and res.ons.ve capacity control, and only requires.rough filtration of the s.urce water for s.aling- and fouling-free operations. The pres.nt s.udy has.been conducted for the water flow at temperature of around 22-30℃ and atmos.heric pres.ure as.the firs. s.ep for inves.igation of the performance characteris.ics.of Rs.E. The multiply factor extremal experiments.conducted with the Box-Wils.n＇s.method have revealed the s.linity of the condens.te, the temperature of s.eam ins.de the s.percavity, and dependence of the s.ape of s.percavity on the rate of s.eam extraction and rotation s.eed of impeller. The s.ape of impeller and the expected s.percavitating effects.it generates.have been confirmed by experimental res.lts.at the rotation s.eed of 5430 rpm （round per minute）. The des.gn of the s.eam extraction openings.has.been approved during the evacuation of s.eam. The experimental dependencies.have been obtained in form of s.atis.ically valid regres.ion equations. which can be us.d for engineering des.gn of Rs.E.

The aim of this.inves.igation was.to define the effectivenes. of non-contact drying us.ng ultras.nic vibrations. Dis. radiators.were us.d for carrying out experiments. and a s.ecial drying chamber was.des.gned to provide res.nant amplification of ultras.nic vibrations.(from 130 to 150 dB). Drying of gins.ng and other vegetables.demons.rated that the application of ultras.nic vibrations.reduced power inputs.by 20% in comparis.n with convective drying. It als. led to a decreas. of 6% in final mois.ure content, if the duration of drying was.cons.ant. The level of intens.fication of ultras.nic drying was.high (up to 50 g for 1 kg of drying material), which helped to lower the temperature of the drying agent and improve the quality of the dried products.
