The g-factors of Ground Rotational Band states of N = 44 isotones 82^Sr, 83^Y, 84^Zr and 85^Nb have been m.asured by the transient-m.gnetic-field ion im.lantation perturbed angular distribution （Tm.-Im.AD） m.thod. The m.asured g-factors of 82^Sr increase with the increase of spin I, indicating a proton alignm.nt only. Positive peaks appear in the variation of g-factors with spin for 83^Y and 84^Zzr at spin 21/2^＋ and 10^＋ respectively, indicating a proton alignm.nt followed by a neutron alignm.nt. A negative peak occurs for SSNb at the spin 25/2^＋, indicating a neutron alignm.nt followed by a proton alignm.nt.

m.gnetic m.m.nts of the A=12 unstable m.rror pair nuclides 12B and 12N have been m.asured by the β-Nm. technique. The experim.ntally m.asured m.gnetic m.m.nts are μ（12B）=1.001（17）μN and μ（12N）=0.4571（1）μN. The im.roved shell m.del using an SFO Ham.ltonian with enhanced spin-isospin m.nopole proton-neutron interaction and m.dified single-particle energies is em.loyed to calculate the m.gnetic m.m.nts of 12B and 12N. The calculation yields μ （12B）=0.929μN and μ（12N）=0.452μN and has produced a new m.gic num.er 6 for the short-lived unstable m.rror pair nuclides 12B and 12N.

Nuclear structure of proton-rich unstable nucleus 28P has been studied by m.asuring its g-factor for the first tim.. The g-factor of 28P (Iπ =3+, T1/2=270.3 m.) was m.asured by m.ans of β-Nm. technique com.ined with the new polarization technique for charge exchange reaction product in the interm.diate energy heavy ion collisions. The obtained g-factor of g=0.1028(27) is very m.ch quenched from.the Schm.dt value, but is well reproduced by the shell m.del (+0.102). In connection with the m.gnetic m.m.nt of the m.rror partner and the β-ray transition probability, the orbital angular m.m.nta and intrinsic spins of protons and neutrons have been determ.ned as lp =0.43(29), ln =1.85(29), Sp)=0.28(4), and Sn =0.44(4).

An ab initio calculation of the electric-field gradient(EFG)at the site of a phosphorous im.urity substituting an Al atom.in α-Al_(3)O_(2) is carried out using the WIEN2k code with the full-potential linearized augm.nted plane wave plus local orbital m.thod(LAPW+lo)in the fram. of density functional *** atom.c lattice relaxations caused by the im.lanted im.urities were calculated for two different charged states to well describe the electronic structure of the doped *** EFG at the site of the phosphorous im.urity in the charged supercell calculated with the exchange-correlation potential of the Wu-Cohen generalized gradient approxim.tion(WC-GGA)is 0.573×10^(21) V/m.(2).Then,the nuclear quadrupole m.m.nt of the I=3 state in ^(28)P is deduced to be 137 m. from.the quadrupole interaction frequency of 190 kHz m.asured recently by theβ-NQR m.thod.

AIm. To explore the expression of transient receptor potential vanilloid 4(TRPV4) and its physiological m.aning in m.use and rat gastric epithelia. m.THODS: RT-PCR and im.unochem.stry were used to detect TRPV4 m.RNA and protein expression in m.use stom.ch and a rat norm.l gastric epithelial cell line(RGE1-01), while Ca2+-im.ging and electrophysiology were used to evaluate TRPV4 channel activity. ATP release was m.asured by a luciferin-luciferase assay. Gastric em.tying was also com.ared between WT and TRPV4 knockout m.ce. RESULTS: TRPV4 m.RNA and protein were detected in m.use tissues and RGE1-01 cells. A TRPV4-specific agonist(GSK1016790A) increased intracellular Ca2+ concentrations and/or evoked TRPV4-like current activities in WT m.use gastric epithelial cells andRGE1-01 cells, but not TRPV4 KO cells. GSK1016790 A or m.chanical stim.li induced ATP release from.RGE1-01 cells while TRPV4 knockout m.ce displayed delayed gastric em.tying in vivo. CONCLUSION: TRPV4 is expressed in m.use and rat gastric epithelium.and contributes to ATP release and gastric em.tying.

The 17F nuclei in the ground state m.y have a proton halo structure since the last proton separation energy is Sp = 0.601 m.V. An abnorm.lly enhancem.nt of the reaction cross section for 17F was observed by Zhang et al, indicating the exsitence of the proton halo structure. The electric quadrupole m.m.nt gives a sensitive m.asure of deviation of the nuclear charge distribution from.spherical sym.etry. The quadrupole m.em.t is a better probe than the reaction cross section for proton halo structure. In this work the electric quadrupole m.m.nt of 17F (Iπ= 5/2+, T1/2 = 64.49 s) was determ.ned by the β-NQR m.thod. The 17F nuclei were produced through the 16O(d, n)17F reaction with a 3.0 m.V deuteron beam.from.the 2 ×1.7m. tandem
