摘要:
Disclosed are compositions and methods of making a liquid fertilizer additive of biodegradable polymers and/or oligomers comprised of utilizing a non-aqueous polar, aprotic organo liquid (NAPAOL) as the reaction medium for the reaction of aldehyde(s) with cyano-containing nitrification inhibitors that have one or more groups that react with the aldehyde(s) wherein said reactive groups are selected from the group consisting of a) primary and secondary amines, b) amides, c) thiols, d) hydroxyls and e) phenol.

The present invention relates to increasing longevity of the nitrogen content of soil through improved liquid delivery formulations of nitrification inhibitors. The liquid formulation can also be comprised of nitrification inhibitors and optionally urease inhibitors that are blended solutions of each. The nitrification inhibitors are present in a mixture that comprises both a protic and an aprotic solvent system. The novel formulations are designed to be applied to fertilizers, especially urea and manure based fertilizers. The delivery formulations provide an environmentally sound and inherently safe solvating system that improves the storage stability of the urease inhibitors by utilizing liquid organic non-water containing solvents, maintains the nitrification inhibitors in solution to storage temperatures of at least 10° C., and provides improved application to fertilizer of nitrification inhibitors. These delivery formulations enable safe storage, transport and subsequent application or blending with urea-based or manure-based fertilizers that can be applied to soil in either a liquid or granular form to provide improved nitrogen retention in the soil for uptake for plant life.

A method of power system preventive control candidate measures identification self-adaptive to external environment, which is applicable to dynamic identification of stations and power equipment under the effect of calamity, and judgment of preventive control measures that lose or restore control capability, and those for which control range or cost has changed. Automatic online identification of set of preventive control candidate measures includes two tasks: identification of stations and power equipment under the effect of calamity, and adjustment of the space of preventive control measures. According to information of power transmission line fault probability due to calamity, online dynamic quantitative assessment of stations and equipment is performed under the effect of external environment, and automatically correct control range and control cost of the measures according to the effect on equipment, so that the result of preventive control adapts to real-time external environment, ensuring feasibility and economy of auxiliary decision making.
摘要:
A constructing method for a concrete cylinder of a construction steel bar of a high-rise steel structure adopts a constructing method of supporting inside and climbing outside. The outside of the cylinder adopts hydraulic mutual-climbing adhesive lifting scaffold creeping formwork system (100), and also has an outside wallboard mechanical formwork erection function and an outer frame protection function. For the inside of the cylinder, except that an appropriate structure is left for later processing according to a schedule requirement, beam walls all adopt a steel cylinder support to perform formwork erection, so as to greatly reduce the workload of repeatedly mounting/dismantling the scaffold and the formwork at a high place. The scaffold itself carries the formwork erection system, so formwork erection and formwork removal can be mechanized, thereby reducing the risk of formwork erection and formwork removal at a high place.

Exemplary methods, apparatuses, and systems receive a first user action, by a user within a network service, with respect to a first object displayed or referenced on the network service. Demographic information for the user is received and a counter for a category representing the first user action, the first object, and the demographic information is identified and incremented. The demographic information may include a history of a second user action with respect to a second object. Counters with the highest values for a category represent the highest ranked objects in the category. Upon receipt of a request for a number of objects for the category, objects that correspond to counters with the highest values for the category are selected and transmitted as a ranked list of recommended objects for display by a user.

Methods, systems, and apparatus, including computer program products, in which an input method editor receives Roman character inputs, identifies keywords for candidate sets of a non-Roman character, and identifies an associated resource location. Upon identifying an associated resource location, associating the resource location with the candidate set of non-Roman characters.
摘要:
Disclosed are a method and a device utilizing barcode images to communicate between a mobile terminal and a backend server and a mobile terminal thereof, which can correctly decode a barcode image of any code format, ensure the security of user information, and provide services on the side of the mobile terminal in the absence of the backend server. The method of the present invention includes the following steps: registering as a user of the backend server through the mobile terminal; taking a picture of the barcode image by using a camera disposed in the mobile terminal; decoding the taken barcode image to obtain coding information; parsing the coding information to determine whether the barcode image is generated according to a preset coding rule; the mobile terminal extracting service information corresponding to the coding information; the mobile terminal sending a service providing request message to the backend server; and the backend server providing a service to the mobile terminal according to content of the service providing request message.
