We experimentally demonstrate efficient generation of high-energy(82 μJ) narrowband 2.05 μm pulses pumped with 1 mJ broadband Ti:sapphire laser pulses, utilizing dual-chirped optical parametric amplification(DC-OPA)in a BBO crystal. The narrowband 2.05 μm pulses will be primarily used for seeding an Ho:YLF laser, which solves the synchronization issue when Ti:sapphire and Ho:YLF lasers are needed for developing midinfrared lasers. The narrowband 2.05 μm pulse from the unique DC-OPA design can seed the Ho:YLF laser much more efficiently than the broadband 2.05 μm pulse from traditional OPA technology.

BACKGROUND： Acupuncture improves the prognosis of neonatal hypoxic-ischemic encephalopathy （HIE）. However, the cytological mechanism of acupuncture therapy remains poorly understood. In situ neural stem cell （NSC） proliferation theory proposes that the proliferation and differentiation of NSCs plays an important role in HIE treatment with acupuncture. OBJECTIVE： To investigate NSC proliferation and differentiation in the brain of a rat model of HIE during acupuncture at ren, Du, and urinary bladder meridians. DESIGN, TIME AND SEB＇ING： A randomized, controlled animal experiment was performed at the Central Laboratory of Shantou University Medical College from July 2005 to June 2009. MATERIALS： A 32# 1-cun stainless steel acupuncture needle was purchased from Suzhou Acupuncture Supplies Co. Ltd., ***： A total of 90 Sprague-Dawley rats, aged 7 days, were randomly assigned to acupuncture, model and normal groups, with 30 animals in each group. Animals in acupuncture and model groups were subjected to left common carotid artery ligation followed by hypoxia for 2 hours to establish neonatal HIE models. Acupuncture group rats underwent acupuncture at ren, Du, and urinary bladder meridians, once a day. MAIN OUTCOME MEASURES： The number, appearance, and distribution of bromodeoxyuridine （BrdU）-positive cells in the cerebral cortex and hippocampus of each group were compared. In addition, NSC differentiation in the occipital cortex and hippocampal dentate gyrus 40 days following model establishment was ***： BrdU-positive cells were dispersed in the cerebral cortex and hippocampus. The number of BrdU-positive cells in occipital cortex and hippocampal dentate gyrus of HIE rats remained unchanged following 3 and 7 days of acupuncture, but a significant increase was detected on days 14 and 28 （P 〈 0.01 or P 〈 0.05）. At 40 days, immunofluorescence showed that a majority of BrdU-positive cells were co-lableled with the neuron marker, and neuron specific enola

Domestic wastes have become an importer topic of environmental protection research. From the social cost of treating domestic wastes, this article analyzes present environmental pollution caused by neglected externality when we discharge domestic wastes in the method of analysis on the difference between marginal personal cost and marginal social cost; It also proves the necessity and the importance of levying pollution tax and proposes the measures of eontrolling environmental potlution caused by domestic wastes.

Nanoscale Sb doped titanium dioxide thin films photocatalyst （Ti1-xSbO2） were obtained from dip-coating sol-gel method. The influence of dopant Sb density on the crystal structure and the phase transformation of the thin tilms were characterized by X-ray diffraction （XRD） and Raman spectra. The results of XRD showed that as prepared lilms were not only in anatase state but also in brookite. The crystalline size was estimated to be around 13.3-20 nm. Raman spectra indicated there coexisted other phases and a transformation from brookite to anatase in the samples doped with 0.2% Sb. After doping a proper amount of Sb, the cryst,allization rate and the content of the anatase Ti1-x, SbO2 in the thin films was clearly enhanced because Sb replaced part. of the Ti of TiO2 in the thin films. The anode current density （photocurrent density） and the first order reaction speed constant （k） of *** films doped with 0.2% Sb reached 42.49 μA/cm^2 and 0.171 h/cm^2 under 254 nm UV illumination, respectively, which is about 11 times and 2 times that of the non doped TiO2 anode prepared by the same method respectively.
