The fact that this condition is also the identifier of thermodynamic equilibrium, makes each and every point along the reversible path a state of equilibrium, and the reversible path, as expressed by a noted thermodynamic author, “a dense succession of equilibrium states”. The difficulties with these notions are plural. The fact, for example, that systems need to be forced out of equilibrium via the expenditure of work, would make any spontaneous reversible process a consumer of work, this in opposition to common thermodynamic wisdom that makes spontaneous reversible processes the most efficient transformers of work-producing-potential into actual work. The solution to this and other related impasses is provided by Dialectical Thermodynamics via its previously proved notion assigning a negative entropy change to the energy upgrading process represented by the transformation of heat into work. The said solution is here exemplified with the ideal-gas phase isomerization of butane into isobutane.展开更多

The kamafugite magma show near\|primary magma characteristics. Strong incompatible elements concentrations in the volcanic rocks infer the kamafugite magmas may be origined from a enrichment mantle sources earlier.Four groups of deep\|seated xenoliths were collected from a kamafugite lava in West Qinling, Gansu province, China: (1)spinel Iherzolite and garnet Iherzolite; (2) harzburgite; (3) dunite and (4) clinopyroxenite. All suite of peridotite xenoliths are Cr\|diopside series. The main textures of peridotite xenoliths are granoblastic, porphyroclastic and granular, but the textures of clinopyroxenite are mainly poikilitic. The textural characteristics, mineral chemical variations and mineral geothermometric data show that the mantle source region of the Cenozoic kamafugite magam are very complex and undertook partial melting and enrichment associated with alkaline metasomatism by fluid and carbonatite melts. Geothermometry indicates the equilibration p and T conditions of the spinel lherzolite and garnet lherzolite are 970℃, 18 9GPa and 1219℃,27 61GPa corresponding to depth of 62km and 92km representatively. We suggest, combining with geophysical data, the spinel lherzolite formed at the top of upper mantle, the garnet lherzolite represent the base of lithosphere or the top of asthenosphere, but the clinopyroxenite is formed by cumulation in shallower magma reservoir. Kamafugite magmas formed within the stability field of garnet lherzolite by partial melting, the partial melting degree is only about 1%~2%. There is a superheating condition in Cenozoic mantle of West Qinling, which may be related to strong uplift of Qingzang (Tibet) plateau since cenozoic and extrusion east forward of asthenosphere beneath the Qingzang (Tibet) plateau.展开更多

METHODS:Sixty healthy male Sprague-Dawley rats were divided randomly into an ANP group(ANP model +CTX,n=20),treatment group(ANP model+CTX +CQCQD,n=20)and control group(normal rats+ CTX,n=20).ANP models were induced by retrograde intraductal injection of 3.5%sodium taurocholate (1 mL/kg),and the control group was injected intraductally with normal saline.All rats were injected introperitoneally with 0.42 g/kg CTX(at 12-h intervals for a continuous 72 h)at 6 h after intraductal injection. Meanwhile,the treatment group received CQCQD (20 mL/kg)intragastrically at 8-h intervals,and the ANP and control group were treated intragastrically with normal saline.At 15 min after the last CTX injection,blood and pancreas samples were collected for the determination of CTX concentration using validated high-performance liquid chromatography. Pathological changes and wet-to-dry-weight(W/D) ratio of pancreatic tissue were examined. RESULTS:Serum CTX concentrations in three groups were not significantly different.Pancreatic CTXconcentration and penetration ratio were lower in ANP group vs control group(4.4±0.6μg/mL vs 18.6± 1.7μg/mL,P=0.000;5%vs 19%,P=0.000),but significantly higher in treatment group vs ANP group (6.4±1.7μg/mL vs 4.4±0.6μg/mL,P=0.020;7% vs 5%,P=0.048).The histological scores and W/D ratio were significantly decreased in treatment group vs ANP and control group. CONCLUSION:CQCQD might have a promotive effect on CTX concentration in pancreatic tissues of rats with ANP.展开更多
