Let R be a Noetherian ring, I and J two ideals of R, m.an R-m.dule and t an integer. Let S be a Serre subcategory of the category of R-m.dules satisfying the co ondition CI, and N be a finitely generated R-m.dule with SuppRN= V（a） for som. a ∈ W（I, J）. It is shown that if ExtR^J（N,HI^i,J（m.） ∈ S for all i 〈 t and all j 〈 t - i, then Ha^i（m. ∈ S for all i 〈 t. Let S be the class of all R-m.dules N with divm. N ≤ k, where k is an integer. It is proved that if Ha^i（m. ∈ S for all i 〈 t and all a ∈ W（I, J）, then HI^i,j（m. ∈ S for all i 〈 t. It follows that inf{i ： HI^i,j（m. S} = inf（inf{i ： Ha^i（m. S）： a ∈W（I,J）}.

A theoretical study of the dynam.cal behaviors of the interaction between a two-level atom.with a m.rse potential in the fram.work of the Jaynes Cum.ings m.del （JCm. is discussed. We show that this system.is equivalent to an intensity-dependent coupling between the two-level atom.and the non-deform.d single-m.de radiation field in the presence of an additional nonlinear interaction. We study the dynam.cal properties of the system.such as, atom.c population inversion, the probability distribution of cavity-field, the m.ndel param.ter and atom.c dipole squeezing. It is shown how the depth of the m.rse potential can be affected by non-classical properties of the system. m.reover, the tem.oral evolution of the Husim.-distribution function is explored.

In the present investigation, Ni_（50）Ti_（25）Al_（25）（at.%） m.chanically alloyed powder is deposited on carbon steel *** the coating process, the substrate is heated to tem.erature ranging from.room.tem.erature to 400℃. The m.crostructure, porosity, m.crohardness, adhesion strength, and corrosion behavior of the coating are investigated at different substrate tem.eratures. Results show that coating porosity is lower on high tem.erature surface. m.crohardness and adhesion strength of the deposition layer on the substrate without preheating have lower values than with preheating. The polarization test result shows that corrosion perform.nce of the coating is dependent on m.cro cracks and porosities and the increasing of substrate tem.erature can im.rove the quality of coating and corrosion perform.nce.

Let R = ⊙n〉0 Rn be a standard graded ring, a ∩ ⊙n〉0 Rn an ideal of R, and m. N two finitely generated graded R-m.dules. This paper studies the hom.geneous com.onents of graded generalized local cohom.logy m.dules. We show that for any i 〉 0, the n-th graded com.onent Hiα（m. N）n of the i-th generalized local cohom.logy m.dule of m.and N with respect to a vanishes for all n 〉〉 0. Som. sufficient conditions are pro- posed to satisfy the equality sup{end（Hiα （m. N）） [ i _〉 0} = sup{end（HiR＋（m. N））｜ i 〉 0}. Also, som. sufficient conditions are proposed for the tam.ness of Hiα（m. N） such that i = fRα＋（m.N） or i = cdα（m.g）, where fRα＋（m.N） and cdα（m.g） denote the R＋- finiteness dim.nsion and the cohom.logical dim.nsion of m.and N with respect to a, respectively. Finally, we consider the Artinian property of som. subm.dules and quotient m.dules of Hjα（m. N）, where j is the first or last non-m.nim.x level of Hiα（m. N）.

In this paper, we present a num.rical m.thod for solving two-dim.nsional VolterraFredholm.integral equations of the second kind（2DV-FK2）. Our m.thod is based on approxim.ting unknown function with Bernstein polyn.m.als. We obtain an error bound for this m.thod and em.loy the m.thod on som. num.rical tests to show the efficiency of the m.thod.

Kerosene-alum.na nanofluid flow and heat transfer in the presence of m.gnetic field are studied. The basic partial differential equations are reduced to ordinary differential equations which are solved sem. analytically using differential transform.tion m.thod. Velocity and tem.erature profiles as well as the skin friction coefficient and the Nusselt num.er are determ.ned analytically. The influence of pertinent param.ters such as m.gnetic param.ter, nanofluid volum. fraction, viscosity param.ter and Eckert num.er on the flow and heat transfer characteristics is discussed. Results indicate that skin friction coefficient decreases with increase of m.gnetic param.ter, nanofluid volum. fraction and viscosity param.ter. Nusselt num.er increases with increase of m.gnetic param.ter and nanofluid volum. fraction while it decreases with increase of Eckert num.er and viscosity param.ter.

Sm.ll high-quality Au/n type-GaAs Schottky barrier diodes （SBDs） with low reverse leakage current are produced using lithography. Their effective barrier heights （BHs） and ideality factors from.current-voltage （I-V） characteristics are m.asured by a Pico am.ere m.ter and hom.-built I-V instrum.nt. In spite of the identical preparation of the diodes there is a diode-to-diode variation in ideality factor and barrier height param.ters. m.asurem.nt of topology of a surface of a thin m.tal film.with atom.c force m.croscope （AFm. shows that Au-n type-GaAS SD consists of a set of parallel-connected m.cro and nanocontacts diodes with sizes approxim.tely in a range of 100-200 nm. Between barrier height and ideality factor there is an inversely proportional dependency. With the diam.ter of contact increasing from.5 μm.up to 200 μm. the barrier height increases from.0.833 up to 0.933 eV and its ideality factor decreases from.1.11 down to 1.006. These dependencies show the reduction of the contribution of the peripheral current with the diam.ter of contact increasing. We find the effect of series resistance on barrier height and ideality factor.
