Torsion simulations of strip rolling were carried out on a 0.06%C-0.3%Mn-0.01%Si steel over the temperature range930 to 1000℃℃.Pass strains of 0.4 were applied at a strain rate of *** times of 0.5s,1s,1.5s and 3s were employed to determine the mean flow stresses（MFS’s）applicable to strip *** means of double differentiation,critical strains of 0.04and 0.11 were established for the initiation of dynamic transformation and dynamic recrystallization,*** is shown that the dynamic transformation of austenite to ferrite takes place above the Ae3temperature,resulting in significantly lower than expected MFS *** nucleation of ferrite reduces the rolling load and modifies the *** interpass times produce larger decreases in MFS than longer ones because of reduced recovery during short interpass intervals.

Background： A novel approach to modelling individual tree growth dynamics is proposed. The approach combines multiple imputation and copula sampling to produce a stochastic individual tree growth and yield projection system. Methods： The Nova Scotia, Canada permanent sample plot network is used as a case study to develop and test the modelling approach. Predictions from this model are compared to predictions from the Acadian variant of the Forest Vegetation Simulator, a widely used statistical individual tree growth and yield model. Results： Diameter and height growth rates were predicted with error rates consistent with those produced using statistical models. Mortality and ingrowth error rates were higher than those observed for diameter and height, but also were within the bounds produced by traditional approaches for predicting these rates. Ingrowth species composition was very poorly predicted. The model was capable of reproducing a wide range of stand dynamic trajectories and in some cases reproduced trajectories that the statistical model was incapable of reproducing. Conclusions： The model has potential to be used as a benchmarking tool for evaluating statistical and process models and may provide a mechanism to separate signal from noise and improve our ability to analyze and learn from large regional datasets that often have underlying flaws in sample design.

Background: The department of defense's field manual(FM) 3-11 is among the military's field manuals for preparing for, reacting to and recovering from chemical, biological, radiological and nuclear attacks. Since post 9-11, U.S. military service members have been deployed in the global war on terrorism. This study attempted to determine the effectiveness of the FM 3-11 in detecting, deterring or preventing a human-borne with bioagent(HBBA) terrorist breach at an entry control point(ECP).Methods: This time-specific, cross-sectional study disseminated a validated survey tool with Cronbach's α>0.82 to respondents who have had antiterrorism training and combat ECP experience. The return rate was greater than 75.0%; however, many of the respondents failed to meet the inclusion criteria. Consequently, only 26 questionnaires were included in the ***: The results revealed that while over 60.0% of the respondents either strongly agreed or agreed that biointelligence, the deployment of biodetectors and the use of biowarning systems could be effective in preventing an ECP breach by a terrorist with a bioagent, the use of protective equipment and immunization to decontaminate service members or other tactics, techniques and procedures(TTPs) would never prevent a breach. A large percentage of respondents claimed that soldiers at the ECP lacked the devices or the knowledge to detect an HBBA at an ECP, and 72.0% suggested modifying current ECP TTPs to include education, training and equipment for security personnel at military base ***: If obtained from appropriate sources and communicated to the personnel at the ECP in an effective or timely manner, the possible effectiveness of certain TTPs in the FM 3-11, specifically FM 3-11.86(intelligence), might increase.

Polysubstance Abuse (PSA) greatly complicates an attempt to implicate a single drug as sole cause of an overdose death. Since PSA now occurs in the majority of cases of drug overdoses, many or most overdose deaths are polysubstance overdose deaths. And since many of the substances involved in a polysubstance Overdose Death (POD) are Central Nervous System (CNS) depressants, many of which can cause overdose death themselves, or synergistically with opioids, it is somewhat puzzling that prescription opioids have been singled out as the cause of these deaths—without reference to PSA. This is particularly puzzling in light of the fact that the issues of PSA and POD have been recognized and discussed in the literature since at least the 1960’s and before. we therefore here consider the question: are we facing an “opioid” crisis or, instead, a “polysubstance crisis”? And we wonder if the issue has been over-simplified, to the detriment of the individuals affected, and to society more broadly. There is a need for an “agnostic” respiratory stimulant that can reverse polysubstance-induced respiratory depression.
