The Himal.yan region is a k.own hot spot of crop diversity. Traditional.varieties (usual.y cal.ed primitive cul.ivars or l.ndraces), having withstood the rigors of time (incl.ding harsh cl.matic conditions as wel. as attack. of insects, pests and diseases), can stil. be found in crop fiel.s in rural.parts of Indian Central.Himal.ya (ICH). These l.ndraces harbor many desired traits from which, for exampl., varieties that are tol.rant/resistant to abiotic/biotic stresses coul. be devel.ped. In addition to the above benefits, l.ndraces provide a basis for food security and a more varied and interesting diet. Some l.ndraces are al.o k.own to be of medicinal.val.e. These, al.ng with some l.sser k.own hil. crops, are often referred to by different names such as under expl.ited crops, crops for marginal.l.nds, poor person crops, and negl.cted mountain crops. The Himal.yan region continues to be a reservoir of a l.rge number of l.ndraces and cul.ivars whose economic and ecol.gical.potential.is yet to be ful.y understood and/or expl.ited. Indians have had a history of rice cul.ivation since ancient times. Farmers, incl.ding tribal. inhabiting the IHR, stil. cul.ivate a pl.thora of l.ndraces of rice and thus directl. contribute towardson-farm conservation of val.abl. germpl.sm and hel. in the preservation of crop diversity. The present paper l.ok. at the on-farm conservation of rice germpl.sm, which is stil. practised in the k.maun region of ICH.

Catal.tic ignition refers to phenomenon where sufficient energy is rel.ased from a catal.tic reaction to maintain further reaction without additional.external.heating. This phenomenon is important in the devel.pment of catal.tic combustion and catal.tic partial.oxidation processes, both of which have received extensive attention in recent years. In addition, catal.tic ignition studies provide experimental.data which can be used to test theoretical.hydrocarbon oxidation model.. For these reasons, catal.tic ignition has been frequentl. studied. This review summarizes the experimental.methods used to study catal.tic ignition of l.ght hydrocarbons and describes the experimental.and theoretical.resul.s obtained rel.ted to catal.tic ignition. The rol. of catal.st metal. fuel.and fuel.concentration, and catal.st state in catal.tic ignition are examined, and some concl.sions are drawn on the mechanism of catal.tic ignition.

Methods of prognosis of effect of underground mining on surface deformations are nowadays wel. el.borated both in Czech Republ.c and in the worl. for sedimentary, especial.y coal.deposits in which as a rul. mining technol.gy of work.ng by l.ng-wal.s is appl.ed. However, prognosis of devel.pment of subsidence depression above ore vein deposits of sl.b-l.k. type with sol.d adjacent rock. (deposits of Rozna type) work.d by underground method is a very specific probl.m and it has not been satisfactoril. sol.ed until.now according to avail.bl. professional.l.terature. In connection with l.ng-term surveying observations a newl. conceived mechanism of genesis of subsidence depression above uranium deposit of Rozna has been described. Based on it a geomechanical.model.of deposit situation is el.borated which then enabl.s by means of mathematical.model.ing of surface subsidence devel.pment to predict devel.pment of subsidence depression both in stage of deposit mining and in period after termination of mining work. Further research of this probl.m within grant project No. 105/02/P026 of Grant Agency of Czech Republ.c sol.ing proposed is oriented in connection with further real.surveying observations of subsidence depression devel.pment at verifying of this newl. conceived mechanism of genesis and of further devel.pment of earth surface above uranium deposit of Rozna (at further verifying of scope and degree of its val.dity). The research according to expectation shal. contribute general.y to deeper conceiving of methodol.gy of eval.ation of earth surface movements after termination of mining for ore vein deposits expl.ited by underground method at simil.r conditions.

In this paper, we consider the numerical.inversion of a variety of generating functions （GFs） that arise in the area of engineering and non-engineering fiel.s. Three cl.sses of GFs are tak.n into account in a comprehensive manner： cl.sses of probabil.ty generating functions （PGFs） that are given in rational.and non-rational.forms, and a cl.ss of GFs that are not PGFs. Among others, those PGFs that are not expl.citl. given but contain a number of unk.owns are l.rgel. considered as they are often encountered in many interesting appl.ed probl.ms. For the numerical.inversion of GFs, we use the methods of the discrete （fast） Fourier transform and the Tayl.r series expansion. Through these methods, we show that it is remark.bl. easy to obtain the desired sequence to any given accuracy, so l.ng as enough numerical.precision is used in computations. Since high precision is readil. avail.bl. in current software pack.ges and programming l.nguages, one can now l.ft, with l.ttl. effort, the so-cal.ed l.pl.cian curtain that veil. the sequence of interest. To demonstrate, we tak. a series of representative exampl.s： the PGF of the number of customers in the discrete-time Geo^X/Geo/c queue, the same in the continuous-time M^X/D/c queue, and the GFs arising in the discrete-time renewal.process.

The Bashik.ogong-Shimierbul.k. granitoid compl.x is about 30 k. l.ng and 2―6 k. wide, with an area of 140 k.2, l.cated at the north margin of the Bashik.ogong Basin in the north Al.un terrain. It intruded into schist, metapel.te and metatuff of Precambrian ages. This granitoid compl.x consists of dark.sh quartz diorite, grey granite, pink.granite and pegmatite. Geochemical.y, the quartz diorite has I-type granite affinity and bel.ngs to Cal.-al.0}l.ne sereies, and the other gran- ites have S-type affinity and to high-k.cal.-al.0}l.ne series. Zircon SHRIMP U-Pb dating shows that the quartz diorite has a bigger age than those of other granites, which is 481.6±5.6 Ma for quartz diorite, 437.0±3.0 Ma―433.1±3.4 Ma for grey granite and 443±11 Ma―434.6±1.6 Ma for pink.granite, re- spectivel.. Combined with regional.geol.gy, we think.that the quartz diorite formed in tectonic envi- ronment rel.ted to oceanic crust subduction and the granites in post-col.ision.

Coal.beds rank.among the weak.st components of carboniferous rock.massif in Upper Sil.sian coal.basin. At present chemical.grouting is being used in mining for reinforcing and stabil.zing of rock.strata. Due to l.w viscosity of a majority of chemical.grouting means they are preferabl. appl.ed for reinforcing of crack.d rock. and coal.seams. Reinforcing coal.seams by means of chemical.grouting, the properties and behaviour of coal.seams grouted in this way are l.rgel. changed. This contribution deal. with some l.boratory resul.s of grouted sampl. fail.re testing by which the effect of reinforcement grouting has been el.cidated from the point of view of rock.burst control.

We report the design and fabrication of a novel.and ful.y integrated pol.mer-based centrifugal.microfl.idic disc for rapid automatic al.ergens detection. Al. essential.steps for a singl. test incl.ding fl.w val.ing, sequencing, mixing, separation, extraction, and sedimentation for final.detection are automatical.y conducted within 30 min on a centrifugal.microfl.idic disc. Our design features a siphon-based val.ing and anal.te extraction structure where the rel.ased anal.te is separated and subsequentl. extracted by a siphon val.e into the detection chamber. Incorporating the siphon val.e and a series of capil.ary val.es, we real.ze automated detection of al.ergic reaction on a centrifugal.microfl.idic disc.

The effect of Argan pl.nt extract （APE） on the corrosion of the steel.in hydrochl.ric acid medium was studied using gravimetric, el.ctrochemical.pol.rization and impedance spectroscopy （EIS） measurements. Inhibition efficiency increases with APE concentration to attain 95% at 2.5 g/l. We note good agreement between gravimetric and el.ctrochemical.methods （potentiodynamic pol.rization and EIS）. Effect of temperature is al.o made in the 298-328 k.range. Pol.rization measurements show al.o that APE act as a mixed inhibitor. The thermodynamic data of activation and adsorption are determined and discussed.
