Stored in methanol+water(55∶5,v/v)at(54±1) ℃ for 7 d and 14 d,degraded rates of azadirachtin A in neem seed methanol extracts were 33.59% and 54.45%,and degraded rates of azadirachtin B in same condition were 11.96% and 21.11%.
The five nutrient elements total storage in depth from 0 to 30 cm of the soil is 206 427.59 kg/hm~2, and available nutrient is 16 618.29 kg/hm~2, the crop nutrient elements storage amount just is occupying about 0.15% of the total nutrient store in the soil of five kind nutrient elements, and 1.95% of the available nutrient store in the soil of five kind nutrient elements.
Results The dose effect and time effect could be expressed by Y=95.4378D-91.2478 and Y=21.32T-3.96 respectively. The activity will decrease slightly with the rising of pH in pH conditions ranging from 5.5 to 8.5.Besides,the activity will not decrease after one year store or boiled at 100℃ for 2h.
The total store is 514.90 kg/hm~2 of the five kinds nutrient elements in the Robinia pseudoacacia forest ecosystem,and the tree layer nutrient element storage amount accouts for about 85.5 percent of total storage.
During the period 1800～1997, the North Pacific has taken up 23.75 GtC of anthropogenic CO_2 in RUN1. The subpolar region is an important export region of absorbed anthropogenic CO_2, where 38%～54% of the absorbed anthropogenic CO_2 is transported to other regions, whereas the region of 20°N～30°N is an important storing region, which amounts to 24% of the total storage in the North Pacific.
2) The water loss percentage and storing losses of team Ⅰwere respectively lower than teamⅡ, by 20.4%,26.4%; team Ⅲ by 23.15%,27.50% respectively(P<0.05),while,with the increasing of concentrated feed levels,the mutton become darker in color,quicker in fat aggradation and lower in cooker meat percentage.
It uses matching algorithms to find a match between questions and sentences stored in a database.
Venoms are excreted by the poison gland or acid gland of mature female wasps and stored in reservoirs.
Solar liquid desiccant air-conditioner is a new air-conditioning system in which liquid desiccant can be regenerated by solar energy and energy can be stored in the form of chemical energy in the liquid desiccant.
Based on a large amount of history data stored in power plants, a way of operation optimization by applying data mining technique is proposed.
The specific endogenous denitrification mainly relies on the internal carbon source (PHB) stored by poly-P bacteria.
We evaluated the possibility of storing the cultures of obligate anaerobic microorganisms (clostridia, acetogenic and sulfate-reducing bacteria, and methanogenic archaea) in 25% glycerol at -70°C for a long time (up to 3 years).
The designed procedures detect most of the defects in control circuits indirectly through data processing and storing devices without the use of control units.
The sodium-storing processes activated under these conditions might be localized in bone, connective tissue (skin), or cartilage.
A personal computer is used to control the measuring procedure and the data processing, imaging, and storing.
This device, operating in the automatic mode as part of the hardware-software NMR system, makes possible recording, processing, and storing experimental results in electronic form.
