In recent years, there has been a rapid development of the wind farms in Japan. It becomes very important to investigate the wind turbine arrangement in wind farm, in order that the wake of one wind turbine does not to interfere with the flow in other wind turbines. In such a case, in order to achieve the highest possible efficiency from the wind, and to install as many as possible wind turbines within a limited area, it becomes a necessity to study the mutual interference of the wake developed by wind turbines. However, there is no report related to the effect of the turbulence intensity of the external flow on the wake behind a wind turbine generated in the wind tunnel. In this paper, the measurement results of the averaged wind profile and turbulence intensity profile in the wake in the wind tunnel are shown when the turbulence intensity of the external wind was changed. The wind tunnel experiment is performed with 500mm-diameter two-bladed horizontal axis wind turbine and the wind velocity in wake is measured by an I-type hot wire probe. As a result, it is clarified that high turbulence intensities enable to the entrainment of the main flow and the wake and to recover quickly the velocity in the wake.

A male infant with clinical features of Noonan syndrome and rapidly progressiv e hypertrophic cardiomyopathy is reported. He manifested severe heart failure an d failure to thrive. Administration of propranolol and cibenzoline improved vent ricular outflow tract obstruction, leading to catch-up growth. Genetic analysis of the patient revealed a novel missense mutation in the PTPN11 gene. Conclusio n:This is the first description of a patient with a Gln510Glu mutation in the pr otein-tyrosine phosphatase, non-receptor type 11 gene. This specific mutation may be associated with a rapidly progressive hypertrophic cardiomyopathy.
