Abstract: Disclosed herein are apyrase inhibitors of Formula (I): Also disclosed herein are methods for using the disclosed inhibitors, including in methods for protecting crops from pests. In one aspect the apyrase inhibitors are useful for enhancing the activity of pesticides for the protection of crops from pathogens and to support crop yield.

Abstract: A weight-adjustable skill toy consists of a string, a first bead, a second bead, at least one first weight, and at least one second weight. The first bead is positioned adjacent to a first end of the string. Likewise, the second bead is positioned adjacent a second end of the string. To change the weight applied at the first bead, the at least one first weight is positioned adjacent the first end and slidably engaged with the first bead. Similarly, to change the weight applied at the second bead, the at least one second weight is positioned adjacent the second end and slidably engaged with the second bead. The first weight, the at least first weight, the second weight, and the at least second weight are utilized to obtain weight configurability.

Abstract: A swinging bob toy having two bobs constrained to, yet slidable along, a string. Each end of the string has a pair of low-mass, spaced-apart stoppers which allows the end of the string to be easily grasped so that smooth transitions can be made between various modes of operation. The string is smooth enough and thick enough that it slides over the fingers and wrists with a minimum of friction and abrasion. The even number of bobs on the string allows for configurations with a symmetrical weight distribution so that one bob may act as an exact counterweight to the other bob.
