“…Because the output current of SCM pin is very small, the buzzer and LED cannot be operated, and the triode is used to enlarge the output current of the microcontroller pin, and the power is switched off at the same time [16]. To make the alarm more obvious, LED uses red.…”

“…In order to solve this problem, use LED to replace the buzzer lamp design, at the same time beside LED in parallel with a wireless module, the alarm signal will be transmitted to the parent control room, the receiver is installed in the control room, with a buzzer alarm, so that it can be separated from the alarm with the baby. Because the wireless transmission function design cost is high, the work load is big, plus my ability is limited, the wireless function has not manifested in the physical object, but is still feasible [16].…”

In twenty-first Century, people's living demand is higher and higher, the SCM application is more and more widespread, and the residents' equipment is constantly intelligent, in which the baby automatic rocking sleep device is a manifestation. For understanding the modern city infant care needs, combined with the development situation both at home and abroad, this paper puts forward a design of intelligent nursing device for baby, analysis device is feasible in theory, through the analysis of the process of care and infant care personnel needs, will demand into the design language, so as to establish the functional framework of infant nursing device, MCU minimum system as the basis, structures of each module, design a baby care device model, so as to assist the care function, ease the pressure on the role of guardian care of infants. The main purpose of this design is to study the diversification of the baby bed, and design a control unit based on single chip microcomputer. The baby bed takes the smallest system of STC89C51 as the main control unit. The external temperature and humidity detection module, the voice sensor detects the baby's crying, and uses the buzzer to play music.

“…However, the material of the membrane is expensive, so its application in industry is blocked. Column chromatography is the most familiar method, separation of taxoids from Taxus extracts is usually made on silica column [16,38], Al 2 O 3 column [39,40], resin column [41], etc. Al 2 O 3 column was used to convert and separate paclitaxel, but only one compound was obtained.…”

Preparative separation and enrichment of four taxoids from Taxus chinensis needles extracts by macroporous resin column chromatography An environment-friendly method was established for the preparative separation and enrichment of four taxoids, namely 10-deacetylbaccatin III (10-DAB III), 7-xylosyl-10-deacetyltaxol (7-xyl-10-DAT), cephalomannine and paclitaxel from Taxus chinensis needles extracts. Characteristics of seven widely used macroporous resins for four taxoids were compared, AB-8 resin offered better adsorption and desorption capacities than others. AB-8 resin column chromatography was used to study the desorption process for four taxoids. The optimum parameters for desorption were 30% ethanol 5 RV for removing impurities, following 15 RV for 10-DAB III, after the desorption of impurities with 35% ethanol 10 RV, 45% ethanol 30 RV for 7-xyl-10-DAT, then 65% ethanol 10 RV for cephalomannine and paclitaxel, the flow rate was 6 RV/ h. After separation on AB-8 resin column chromatography, the contents of 10-DAB III, 7-xyl-10-DAT, cephalomannine and paclitaxel in the product reached 4.58, 13.17, 1.36 and 3.08%, respectively, which were 7.63-, 3.68-, 6.18-and 6.55-fold to those in T. chinensis needles extracts. The recovery yields were 94.96, 77.32, 88.09 and 95.25%. In general, the AB-8 resin column chromatography has the advantages of lower cost, high efficiency and simple procedure. Therefore, it may provide scientific references for the preparative separation and enrichment of taxoids from other T. species.

“…Only a few soft-bodied animal fossils are known from the North China Platform to date. A group of variegated clastic rocks are widely distributed in North China, namely the Mantou Formation formerly subdivided into the Mantou, Maozhuang, and Xuzhuang formations from bottom to top [19]. At many localities, the Mantou Formation has developments of very fine variegated mudstone and shale so it is possible that soft-bodied animals are preserved in it.…”
