We look on these states for a possible regular dependence on their decay as a function of their energy separation between the basic states under different types of environments. We didn’t find regular or significant dependence on this energy separation for the type of environment considered.展开更多

The vaginal content was sampled both before they began using the chosen contraceptive method (see below) and three months later, and then analyzed using the Balance of Vaginal Content (BAVACO) methodology. Five BVSs were defined: 1) normal microbiota;2) normal microbiota with vaginal inflammatory reaction (VIR);3) intermediate microbiota;4) bacterial vaginosis and 5) non-specific microbial vaginitis. The following contraceptive methods were considered: combined oral contraceptive pill (COCP), intrauterine device (IUD), condom (CON), the rhythm method (RHYT) and simultaneous double protection (COCP + CON). The McNemar statistical test was used. COCP (n = 71): 20 samples retained normal BVSs and two were altered;nine out of the 49 altered samples returned to normal;IUD (n = 4): two samples modified their normal BVS to III and IV;CON (n = 25): the VIR increased in 20% of the samples;RHYT (n = 6): four samples retained the normal BVS;and COCP + CON (n = 2): samples preserved their initial BVS (II). The increased frequency of BVS I in the COCP group was significant (x2 = 3.3;p = 0.04). The relative frequency of each BVS was significantly modified, attributed to the type of contraceptive method used. The intake of hormones corrects alterations and retains a normal BVS. The contraceptive methods that use an external factor of local contact either maintain or alter the microbiota and VIR.展开更多

The importance, research value and present-day studies of marine hazardous geology, a newly developing branch of geoscience, are well expatiated. Several often confused concepts and theories are explained and redefined here. The comment on the means of investigations, assessment of marine hazardous geology, as well as its evolution, innovation, existing questions and future tasks are also introduced and presented. The concepts of 'hazard geology', geohazard', 'map of marine hazard geology', 'integrated evaluaton on seafloor stablity' are respectively discussed, including their definition, research objects, methods and contents. The types and classification of marine hazardous geology, principles and methods of marine hazardous geology map compilation, the assessment methods and models of marine hazardous geology environment and seafloor stability and so on are also discussed.展开更多

文摘Using Lindblad approach to study decoherence of quantum systems, we study the decoherence and decay of entangled states, formed by two basic states of a chain of thee qubits. We look on these states for a possible regular dependence on their decay as a function of their energy separation between the basic states under different types of environments. We didn’t find regular or significant dependence on this energy separation for the type of environment considered.
