| 1 | A novel and smart automatic light-seeking flowerpot for monitoring flower growth environment显示文摘Although the flowerpot is widely used for indoor flowers,it cannot meet the needs of intelligent management during the uncared-for period.The objective of this study was to design a new microcontroller-based smart flowerpot.Its overall system was composed of three parts:information collection layer,automatic control layer and data transmission layer.Firstly,in the process of collecting information,the Laiyite criterion and the normalized weighted average algorithm were adopted to improve the accuracy of information collection.Secondly,for making precise control decisions,the fuzzy control was used to achieve automatic on-demand watering.Finally,the method for comparative analysis of regional light intensity was utilized to achieve light-seeking and light-supplementing.Experimental results showed that the smart flowerpot had strong anti-jamming performance for information collection,the relative soil moisture of flowers could be stably maintained near the optimum humidity(65%),and the light was well-distributed on the flower with the error angle of light-supplementing ranged from-3°to 3°. | Xihai Zhang Dong Liu Chengguo Fan Jiali Du Fanfeng Meng Junlong Fang | 2018 | International Journal of Agricultural and Biological Engineering2018，11，2： | 2 |
| 2 | Effects of Agaricus blazei Murill Polysaccharides on Leadinduced Disturbance of Morphology and ASIC1a and ASIC2b Gene Expression in Hippocampus of Rats显示文摘The present study was undertaken to investigate the effects of Agaricus blazei murill polysaccharides on morphology of hippocampus tissue and expression of ASIC1a and ASIC2b mRNA in lead-poisoning rats.Forty SD rats were divided into five groups:control group,lead group,experimental group 1,2,3.After 60d of treatments,hippocampus tissues were observed by HE staining and the expression levels of ASIC1a and ASIC2b mRNA were determined by the flouoreescent quantitative real-time polymerase chain reaction(FQRT-PCR).The results showed that after lead induction,the number of hippocampus neuron increased,cell gap increased,the chromatin was stained lightly;after administration of ABMP,the number of the hippocampus neuron increased as the dose of ABMP rose,cell gap decreased,the chromatin was stained darkly.The expression level of ASIC1a mRNA in hippocampus of rats in ABMP group decreased extremely significantly compared with that in the model group(P<0.01).Lead exposure and ABMP exhibited no significant effects on the expression level of ASIC2b mRNA.ABMP possesses a protective effect on nervous system of rats exposed to lead by combining with lead. | Xin LI Xiru LV Cuiping FENG Mingchang CHANG Hongyan CHENG Junlong MENG | 2014 | Agricultural Biotechnology2014，3，3： | 0 |
