Precast concrete block slope protection is widely used due to its advantages of easy detection and laying, ease organization, the limited time required for construction. In order prevent soil or gravel bedding precast from being subjected wind wave pressures, joints between blocks are usually filled with mortar. However, existing standards do not specify width material joints. Furthermore, exce...

Clonal stability of tree dryness was evaluated in eleven clones of Hevea brasiliensis at the Rubber Research Institute of Nigeria. The experimental design was the randomized complete block with three replicates and ten trees per replicate. The clones were evaluated in three locations. Four stability parameters were applied. The stability parameters were: environmental variance, regression index...

Clinical microbiology laboratory directors come from diverse backgrounds with overlapping but not identical training experiences. Although director responsibilities are defined by CLIA legislation, there is no standardization of job descriptions among hospital or university settings. One job that would make the microbiology director indispensable, if done well, is clinical consultation. Other c...
