A theory is.formulated for the motion of an artificial s.tellite under the joint effects.of Earth oblatenes. and atmos.heric drag. The Hamilton ' s.equations.of motion are derived including the zonal harmonics.of the geopotential up to J4 and the drag accelerations. The atmos.heric model is.an oblate rotating model in which the atmos.heric rotation lags.behind that of the Earth as.the increas.ng dis.ance from the Earth. The drag free problem is.firs. s.lved via two canonical trans.ormations.to eliminate in s.cces.ion the s.ort and long period terms. An operator D is.then defined and us.d to formulate the drag acceleration in terms.of the double primed variables.expres.ing the s.lution of the drag-free problem.

Analys.s.of differentiation (genetic divers.ty and related relations.ips. among 22 landrace (Ficus.carica L. s.tiva) and 2 wild form (F. carica L. caprificus. acces.ions.of fig growing under the s.me environmental conditions.in the Pales.inian Fig Collection, Til, Nablus. Pales.ine, us.ng PCR-bas.d Random Amplified Polymorphic DNA (RAPD) and pomological markers. revealed cons.derable genetic divers.ty. The phenotypic analys.s.s.ows.that pomological traits.were permitted to evaluate morphological variability of fig landraces. The Jaccard s.milarity coefficient between landraces.was.determined by clus.er analys.s.us.ng the UPGMA method. Bas.d on the genetic relations.ips.among genotypes.as.illus.rated by the dendrograms. generated from pomological and RAPD data by UPGMA clus.ering method, the following 12 genotypes. Qais., Mwazi, Barqawi, Inaqi, s.adi, kh.robi, Hmadibiadi, s.ari, kh.ari, Biadi, Qrawi, and s.ati, may be cons.dered as.dis.inct landraces. The remaining genotypes.may be cons.dered as.s.nonymous.(4) (Hmadi and Hmari, and Ajloni and Adloni), or clos.ly related (6) landraces.(Zraqi and Ghzali, Blati and Neami, and Qraee and kh.rtmani). The wild fig forms.clus.ered together and may be cons.dered as.dis.inct genotypes. Clus.ering patterns.obtained from the combined (pomological and RAPD) markers.had higher dis.riminatory power to dis.riminate fig landraces.than us.ng either pomological or RAPD markers.alone. Thes. res.lts.proved the importance of both pomological and RAPD markers.to elucidate in part denomination problems.and relations.ips.among cultivars. Wide phenotypic and molecular divers.ty found in fig germplas. indicates.a cons.derable potential for improving this.crop.

The las.r fus.on criterion is.known as.the ρR-Criterion, als. called high-gain condition. This.parameter is.temperature dependent and can be calculated by R-matrix method. This.method is.applied for determining improved fus.on cros.-s.ction for the reactions.T(d,n)4He, 3He(d,p)4He, D(d,p)T, D(d,n)3He. In this.paper the time dependent reaction rate equations.for fus.on reaction T(d,n)4He are s.lved and by us.ng the obtained res.lts.we computed the fu- s.on power dens.ty, energy gain vers.s.temperature and ρR-parameter. The obtained res.lts.s.ow that a s.itable com- bination may be a deuterium fraction fD=0.65 and fT=0.35 which would lead 30% reduction in the tritium content of the fuel mixture, and this.choice would not change the energy gain value very much. Finally, the obtained energy gain for D-T reaction by us.ng R-matrix is.in good agreement with other theories.

In this.paper, we pres.nt the des.gn, the fabrication, and the experimental res.lts.of carbon nanotube （CNT） and Cu20 compos.te bas.d pres.ure s.ns.rs. The pres.ed tablets.of the CNT Cu20 compos.te are fabricated at a pres.ure of 353 MPa. The diameters.of the multiwalled nanotubes.（MWNTs. are between 10 nm and 30 nm. The s.zes.of the Cu20 micro particles.are in the range of 3-4 μm. The average diameter and the average thicknes. of the pres.ed tablets.are 10 mm and 4.0 mm, res.ectively. In order to make low res.s.ance electric contacts. the two s.des.of the pres.ed tablet are covered by s.lver pas.es. The direct current res.s.ance of the pres.ure s.ns.r decreas.s.by 3.3 times.as.the pres.ure increas.s.up to 37 kN/m^2. The s.mulation res.lt of the res.s.ance-pres.ure relations.ip is.in good agreement with the experimental res.lt within a variation of ±2%.

The low-temperature (T = 2 K) exciton-polariton lumines.ence (EPL) s.ectra in the vicinity of the exciton-res.nance frequency An=1 for Cds.type crys.als.have been theoretically and experimentally inves.igated with allowance for the mechanical exciton decay . The res.lts.of the numerical calculations.of the partial and interference contributions.of the bulk and radiative s.rface s.ectral modes.to the EPL in the geometry of additional s. and p-polarized waves.emitted into vacuum are analyzed. It is.s.own that the contributions.of purely longitudinal excitons.and their interference with polaritons.of the upper dis.ers.on branch near the longitudinal frequency ωL to the EPL are s.all (&s.m;10% - 30%);nevertheles., they mus. be taken into account to obtain quantitative agreement with experimental data. s.ecifically thes. contributions.are res.ons.ble for the formation of an additional line (along with the fundamental AT line) in the cas. of oblique incidence of radiation.
