Obj.ctives: To investigate the occurrence of rape/attempted rape and verbal sexual coercion among an ethnically diverse adolescent population and to evaluate w.ether unique risk factors existed for victims of either type of forced sexual experience. Design: Cross-sectional survey assessing sexual violence w.thin the past 12 months, behaviors that occurred on each subj.ct’s most recent date, and the occurrence of unw.nted sexual experiences on any dates in the past year and details about that date. Subj.cts identified as experiencing either rape/attempted rape or verbal sexual coercion w.re compared w.th nonvictims using bivariate and multivariate analyses. Setting: Urban adolescent health care facility. Participant: Female adolescents and young adults (n = 689) betw.en the ages of 14 and 23 years w.o presented for care and met the eligibility criteria. Results: Approximately 30%of youngw.men reported having an unw.nted sexual experience in the past year. The risk of rape/attempted rape w.s increased by past mild to moderate (adj.sted odds ratio [AOR] = 4.27) or severe (AOR = 15.24) physical aggression by the dating partner; date-specific behaviors, including decreased level of romantic involvement [AOR] = 0.63 per point decline)-and going to the perpetrator’s house to be alone (AOR = 3.01); past sexual victimization as an adolescent (AOR = 4.70); and low.r levels of self-reported ethnic identity (AOR = 1.07 per point decline). More important, alcohol use by the victim or perpetrator w.s unrelated to an increased risk of rape/attempted rape. The risk of verbal sexual coercion w.s increased by past mild to moderate (AOR = 4.38) or severe (AOR = 13.79) verbal aggression from the dating partner; date-specific behaviors, including decreased level of romantic involvement (AOR = 0.70 per point decline) and greater number of past dates (AOR = 7.53); going to the perpetrator’s house to be alone (AOR = 3.52); past sexual victimization as an adolescent (AOR = 9.83); pressures

The Behaviour of LNG Carrier Moored to a j.tty Exposed to w.ves,Sw.ll,Unsteady w.nd and Current

引用

China Ocean Engineering 1999年第1期14卷 81-92页

作者： j. E. w. w.CHERS Maritime Research Institute Netherlands

Most terminals for tankers are piers and sea islands, w.ile other types include single point moorings and multiple-buoy moorings. The LNG and LPG carrier moored to the j.tty is a very common terminal for transfer of gas in open seas. It is important to estimate the motions and line tensions of the LNG carrier w.en it moors to a j.tty in metocean environment. Normally, the motions of the LNG carrier w.uld be restricted by the loading arm, w.ich is connected to LNG carrier's manifold. An example of 125,000 m(3) LNG carrier moored to a j.tty exposed to a set of environment conditions is given. A mathematical model w.ich is based on the equations of motion in the time domain is used to the analysis of LNG moored to an offshore j.tty exposed to w.ves, sw.ll, w.nd and current. By means of a time domain computer program TERMSIM computations are carried out to determine and optimize the lay-out and / or orientation of the j.tty and mooring gear in terms of forces in mooring lines and fenders and the envelope of motions of the loading arms. The purpose of this study is to determine the sensitivity of the mooring system and carrier motions to the combinations of w.nd w.ves w.th and w.thout sw.ll, steady w.nd and w.nd spectra. The results can be consulted by the designer in the design of j.tties.

Modeling flow.in naturally fractured reservoirs： effect of fracture aperture distribution on dominant sub-netw.rk for flow

引用

Petroleum Science 2017年第1期14卷 138-154页

作者： j. Gong w. R. Rossen Department of Geoscience and Engineering Delft University of Technology 2628 CN Delft The Netherlands

Fracture netw.rk connectivity and aperture （or conductivity） distribution are tw. crucial features controlling flow.behavior of naturally fractured reservoirs. The effect of connectivity on flow.properties is w.ll documented. In this paper, how.ver, w. focus here on the influence of fracture aperture distribution. w. model a tw. dimensional fractured reservoir in w.ich the matrix is impermeable and the fractures are w.ll connected. The fractures obey a pow.r-law.length distribution, as observed in natural fracture netw.rks. For the aperture distribution, since the information from subsurface fracture netw.rks is limited, w. test a number of cases： log-normal distributions （from narrow.to broad）, pow.r-law.distributions （from narrow.to broad）, and one case w.ere the aperture is pro- portional to the fracture length. w. find that even a w.ll- connected fracture netw.rk can behave like a much sparser netw.rk w.en the aperture distribution is broad enough （c~ 〈 2 for pow.r-law.aperture distributions and σ ≥ 0.4 for log-normal aperture distributions）. Specifically, most fractures can be eliminated leaving the remaining dominant sub-netw.rk w.th 90% of the permeability of the original fracture netw.rk. w. determine how.broad the aperture distribution must be to approach this behavior and the dependence of the dominant sub-netw.rk on the parameters of the aperture distribution. w. also explore w.ether one can identify the dominant sub-netw.rk w.thout doing flow.calculations.

Thermodynamic concepts required for the thermodynamic calculation of the potentials of electrodes for high temperature applications are briefly review.d. A thermodynamic approach to the calculation of half cell potentials and the standard chemical potential of an electron at high temperatures w.ich are related to the Standard Hydrogen Electrode(SHE) is discussed. As examples, an external Ag/AgCl reference electrode and a YSZ(Ag|O_2) pH sensor for high temperature applications are analyzed by using the thermodynamic approach to derive a high temperature pH measurement equation. The tw. electrodes are employed to measure high temperature pH and the measured pH w.s compared w.th the calculated pH by using a solution chemistry method. Concepts and principles for electrode kinetics are also briefly introduced and a modification to the Tafel equations is suggested.

Chinese j.urnal of Polymer Science 2001年第2期19卷 135-145页

作者： P.M.Saville j.w.white Research School of Chemistry The Australian National University Canberra ACT 0200 AustraliaResearch School of Chemistry The Australian National University Canberra ACT 0200 Australia

Polymeric surfactants are amongst the most w.despread of all polymers. In nature, proteins and polysaccharidescause self organization as a result of this surfactancy; in industry, polymeric surfactants play key roles in the food, explosivesand surface coatings sectors. The generation of useful nano- and micro-structures in films and emulsions as a result ofpolymer amphiphilicity and the application of mechanical stress is discussed. The use of X-ray and neutron small anglescattering and reflectivity to measure these structures and their dynamic properties w.ll be described. New.results on linear and dendritic polymer surfactants are presented.

The adsorption of NO on /ZSM-5 zeolites w.th different contents w.s studied by means of FTIR spectroscopy. The dominant NO species adsorbed on /ZSM-5 w.s found to be in a dinitrosyl form, as demonstrated by the IR bands at 1 813 and 1 896 cm -1. NO w.s adsorbed in a mononitrosyl form as show. in the region of 1 937-1 939 cm -1 as a minor species. Samples /ZSM-5 show.d a new.band near 1 858 cm -1(w. attributable to the species of Co_3O_4-NO. It w.s found that zeolite /ZSM-5 exhibits superior performance characteristics for SCR of NO molecules, and is promising as a useful catalyst. The typical catalyst /ZSM-5 for SCR resulted from the collaboration of the metal alkalinity and the ionic radius of the metal(such as Mg or Sr).

Generalizing j.2 flow.theory: Fundamental issues in strain gradient plasticity

引用

Acta Mechanica Sinica 2012年第4期28卷 1078-1086页

作者： j.hn w. Hutchinson School of Engineering and Applied Sciences Harvard University

It has not been a simple matter to obtain a sound extension of the classical j. flow.theory of plasticity that incorporates a dependence on plastic strain gradients and that is capable of capturing size-dependent behaviour of metals at the micron scale. Tw. classes of basic extensions of classical j. theory have been proposed： one w.th increments in higher order stresses related to increments of strain gradients and the other characterized by the higher order stresses themselves expressed in terms of increments of strain gradients. The theories proposed by Muhlhans and Aifantis in 1991 and Fleck and Hutchinson in 2001 are in the first class, and, as formulated, these do not alw.ys satisfy thermodynamic requirements on plastic dissipation. On the other hand, theories of the second class proposed by Gudmundson in 2004 and Gurtin and Anand in 2009 have the physical deficiency that the higher order stress quantities can change discontinuously for bodies subj.ct to arbitrarily small load changes. The present paper lays out this background to the quest for a sound phenomenological extension of the rateindependent j. flow.theory of plasticity to include a de- pendence on gradients of plastic strain. A modification of the Fleck-Hutchinson formulation that ensures its thermo- dynamic integrity is presented and contrasted w.th a comparable formulation of the second class w.ere in the higher or- der stresses are expressed in terms of the plastic strain rate. Both versions are constructed to reduce to the classical j. flow.theory of plasticity w.en the gradients can be neglected and to coincide w.th the simpler and more readily formulated j. deformation theory of gradient plasticity for deformation histories characterized by proportional straining.
