| 20090029856 | Hinokitiol As A Plant Pesticide - The present invention discloses that a natural tropolone compound, hinokitiol, also known as β-Thujaplicin as an effective biopesticide for use in controlling plant pests. In particular, hinokitiol and/or salts thereof may be used in modulating non-Erwinia plant microbial infection or in the formulation of a non-Erwinia antimicrobial agent. Alternatively, hinokitiol may be used as a natural herbicide to control the germination and growth of weeds. The formulation used in the present invention may contain a chelator, pH adjustor and UV protection agent in an amount effective to stabilize said hinokitiol. | 01-29-2009 |
| 20090099022 | NATURAL HERBICIDE CONTAINING LEMONGRASS ESSENTIAL OIL - The present invention discloses that a plant essential oil, lemongrass oil, is an effective pre and post emergence herbicide on both broadleaved and grass weeds. The lemongrass oil may be combined with corn oil and/or other oil and/or an organic acid, surfactants and other formulation ingredients to control the germination and growth of weeds. As a natural, non-toxic compound, it can be used as a safe alternative for weed control in organic farming systems. | 04-16-2009 |
| 20100160391 | Substituted Aminopyridines as Fluorescent Reporters for Amide Hydrolases - The present invention provides conjugates comprising a substituted aminopyridine covalently attached to an organic molecule via an amide bond. Such conjugates find utility as substrates for amide hydrolases, where the substituted aminopyridine acts as a fluorescent reporter of amide hydrolase activity. As a result, the conjugates described herein can advantageously be used in assays to detect amide hydrolase activity based upon measuring the fluorescence of a substituted aminopyridine that is released after amide hydrolysis. The conjugates of the present invention are also particularly useful in screening assays, which enable the identification of inhibitory molecules for amide hydrolases and other enzymes. The identified amide hydrolase inhibitors can be used in the treatment of a variety of diseases and disorders associated with aberrant amide hydrolase activity. | 06-24-2010 |
| 20100266717 | CHEMICAL AND BIOLOGICAL AGENTS FOR THE CONTROL OF MOLLUSCS - Compositions and methods for controlling molluscs, members of the Gastropoda and Bivalvia classes which includes but is not limited to lactones, lactams, carbamates, amides, and/or carboxylic acid containing compounds as active ingredients and/or compounds derived from | 10-21-2010 |
| 20110021358 | USE OF SARMENTINE AND ITS ANALOGS FOR CONTROLLING PLANT PESTS - Methods and compositions for controlling plant pests, particularly weeds and/or plant phytopathogens using sarmentine and/or analogs thereof are disclosed. | 01-27-2011 |

| 20100058309 | Method and system for upgrading firmware of a card reader - The invention discloses a method and a system of upgrading firmware of a card reader. In the method, a card reader is connected to an IC card; the card reader determines whether the IC card is an IC card for upgrading, if it is, the card reader makes one-way or mutual authentication with the IC card; after a successful authentication, the card reader acquires files for upgrading the firmware of the card reader. The system includes a card reader and an IC card. The firmware of card reader is upgraded in the invention by acquiring the files for upgrading from an IC card in which the files for upgrading are pre-stored. The invention improves the efficiency of upgrading the card reader and also improves the security of the upgrading by the authentication between the card reader and the IC card. | 03-04-2010 |
