Through the micro biosensor, the dynamic change of dopamine in the striatum due to lead intoxication was studied, and the 1/2 LD 50 of PB and time effect curve of dopamine in the rat due to 1/2 LD 50 PB intoxication was obtained.
This paper discusses the theory and method of finite element analysis of large deformation of rock mass creep in terms of time effect of deformation and large deformation of rock mass of jinchuan Mine.
④100 mg/L ox-LDL was added for 3, 6, 12, 24 hours, respectively after 96 hours of inoculation, and the supernatant was taken to detect the content of PAI-1 and 6-keto-PGF1α and observe the time effect of ox-LDL.
The D-values of somatic function,mental status,self-evaluation were 4.17±1.87? 5.69±4.81? 1.72±0.88 respectively in intervention group after the time effects were controlled, its′ increased degree was higher than those in control group(P<0.05 or P<0.01).
In three typical codes, it is the most accurate to calculate the general time effects to use CEB-FIP(1990) method, CEB-FIP(1978) method fit the calculation in early time, and ACI-209(1982) is best for the calculation in the final time.
The restrained function of NP to the multiplication of Sf9 cells is obvious(p<0.01)and there is an apparent concentration-effect and time-effect. The LC_(50)(culture 72 h) on Sf9 cells is 0.047 mmol/L.
Concentrations of sodium fluoride of 0.3,1.6,8.0, 20.0 and40.0 mmol/L can significantly inhibit the activity of the enzyme with proportions of 6.6%,18.0%,41.0%, 55.5% and 63.1%,respectively, and with a half inhibitory concentration of 14.8 mmol/L re。 flecting an obvious dose-effect and time-effect relationship。
The results show that NP can promote the growth of BmN cells as the concentration under 0.032 mmol/L(p<0.01). With the concentration increasing,the growth and multiplication of cells are bated(p<0.01),the number of death cells increased obviously,thus there is apparent concentration-effect and time-effect.
The temporal effect analysis indicates that simular to that of developed countries, China's energy consumption intensity presents an apparent inverted “U” shape due to the enormous energy saving effect produced by the large-scale introduction of technology, products and management and to the speeding-up of energy consumption structure evolution.
and the temporal effect of lime-loess strength is expatiated from the view of micro-mechanism. It is proposed that the lime-loess ratio of 3∶7 can be replace by 2∶8 in practical construction in order to save lime as well as meet the requirement of engineering strength. Thus, the research has practical significance.
Scale and time effects on mathematical models for transport in the environment
It is shown that when one approaches the terminator the near polar atmosphere is cooled and the effects of variation of the solar zenith angle modulate the local time effects in both hemispheres.
Temperature and Time Effects on the Acid Corrosion of Steel in the Presence of Acetylenic Inhibitors
Dynamic adaptation of the two systems, in terms of volume or time effects with respect to the preservation of sensitivity and resolving power, is discussed.
A mechanism for achieving the terahertz negative conductivity on transmit time effects during ballistic transport of hot carriers in nanoscale semiconductor heterostructures was theoretically considered.
Time-effect relationship of acupuncture in improving cardiac vegetative nerve function in patients with type II DM
By calculating the area under the curve (AUC), of the time-effect curves of the prodrugs, a significantly improved duration of action was found for those prodrugs which have a slow in vitro hydrolysis rate.
From time-effect curves the area under the curve for separate time intervals was taken as a measure of dopaminergic activity during that interval.
Dose-response and time-effect curves were determined for morphine (1.0-30 mg/kg), levorphanol (0.1 to 3.0 mg/kg), methadone (0.1-3.0 mg/kg), meperidine (1.0-30 mg/kg), oxymorphone (0.03-1.0 mg/kg), and d-amphetamine (0.1-3.0 mg/kg).
Dose-response and time-effect curves were also determined for morphine (1.0-30 mg/kg) in rats that had received multiple injections of morphine over a period of 3 days.
Three independent measures show that this temporal effect is not owing to foraging being more important in the afternoon.
In addition to the contextual impact on locomotor behavior there was also a temporal effect, with security initially dominating the rats' behavior but then declining along with an increased attraction to salient landmarks.
Temporal Effect of Carbofuran, a Carbamate Insecticide in the Interruption of Estrous Cycle and Follicular Toxicity in Female Sw
Temporal effect of 2,4-D on induction of embryogenic nuclellar cultures and somatic embryo development of 'Carabao' mango
The matrix translates the effects of persistence (a temporal effect) into spatialcoordinates and represents the change from near-field to far-field in acontinuous fashion, successfully accounting for both regimes.
