A fabric having first section and having first pores created by the interlacings of yarn in a first pattern, and having a first average pore size. According to some embodiments, the method includes impregnating a porous support with a metal or metal oxide and dissolving the support to release spherical particles. The tubular portion is positioned within an aperture of a workpiece, such that the bracket portion rests on top of the workpiece. As a consequence, the cutting insert cannot be removed by sliding it forwardly in the insert pocket. 2) Method of curatively or preventively combating phytopathogenic fungi in crops, characterized in that an effective, nonphytotoxic amount of one of these fungicidal compositions is applied to the aerial parts of the plants. The method repeats the treatment for a number of semiconductor wafers.
