Predictive analysis of concrete slump using a stochastic search-consolidated neural network.

Attaining a dependable measurement of concrete slump is crucial as it is a valuable indication of concrete workability. On the other hand, complexities associated with costly traditional approaches have driven engineers to use indirect efficient models such as metaheuristic-based machine learning for approximating the slump. While the literature shows promising application of some metaheuristic techniques for this purpose, the large variety of these algorithms calls for evaluating the most capable ones to keep the solution updated.

[Effects of plant growth regulators and nitrogen on germination of Epimedium pseudowushanense after its stems and leaves reaped].

In order to explore appropriate measures to promote germination after the harvest of Epimedium pseudowushanense, 6-BA, urea, ammonium bicarbonate and GA₃ were chosen to spray on the root and rhizomes, and then the biological indicators such as branches, leaf length, leaf width, plant height and so on, were measured in different periods, and the contents of epimedin A, epimedin B, epimedin C and icariin in the dry leaves were detected by HPLC. Results showed that 6-BA 90 mg·L⁻¹(B1), 6-BA 60 mg·L⁻¹(B2),6-BA 30 mg·L⁻¹+urea 300 mg·L⁻¹ (C1), 6-BA 60 mg·L⁻¹+urea 300 mg·L⁻¹(C2),6-BA 60 mg·L⁻¹+ ammonium bicarbonate 300 mg·L⁻¹(C4) significantly increased bud germination in the early period, and the plants quickly set up new system of photosynthesis, the branches in a month of which were higher than the control group respectively by 165.9%, 115.

[Effects of nitrogen on yields and flavonoids contents of Epimedium pseudowushanense in hydroponic conditions].

Nitrogen nutrition divided into concentrations and forms for Epimedium pseudowushanense was studied under hydroponic conditions. There were 7 nitrogen concentrations treatments（N0-N6）which nitrogen concentration was 0, 2.5, 5.

[Research on photosynthetic and eco-physiological characteristics of Epimedium pseudowushannense in different growing age].

Epimedium is a widely used medicinal plants. Due to excessive use of wild resources and resource constraints, artificial cultivation is the only way to achieve sustainable use of resources. E.

[Differences of signaling pathway of lung injury between C57BL/6 and C3H/He mice exposed to fine particle].

Objective: To study the differences of signaling pathway of lung injury between C57BL/6 and C3H/He mice exposed to fine particle.

Methods: By intratracheally instillation, two strains of mice (C57BL/6 mice and C3 H/He) were exposed to fine particle once time per day, for continuously two days. Twenty-four hours after last time exposure, the mice were killed and the lungs were taken out immediately, and put into the liquid nitrogen.

Synchrotron microradiography study on acute lung injury of mouse caused by PM(2.5) aerosols.

In order to investigate FeSO(4), ZnSO(4) (the two of main metal compositions of Shanghai PM(2.5) (particle matter with those aerodynamical diameter <2.5 microm)) effects on acute lung injury, six solutions contained PM(2.

[Study on mouse pulmonary acute injury induced by air-borne PM2.5].

Objective: In order to study the acute toxicity of PM2.5 and to explore the role of immunoreaction and oxidative stress in mouse pulmonary acute injury induced by PM2.5.
