A computer case with adjustable hard disk drive and interface card accommodation space is provided. Designs for supporting transactional programming using transactional memory implemented in hardware, software, and a mixture of the two have emerged recently. , a slab of material similar to that of the substrate, is positioned adjacent the substrate surface so as to overlie an active region of the transistor or diode and a relatively large area of the substrate surrounding the active region. On a first face of the spinning indicator, which faces to the mount, a plurality of semi-circular electrodes are coated at the corresponding positions to the plurality of circular electrodes. The timestamp value may be written into the packet, depending on the packet classification, and checksum-type fields may additionally be updated in the packet. In particular, the present invention relates to a process for enantioselectively producing the -\u03b4-lactone.
