We report the detection of propargyl radical (CH 2 CCH) in cold dark cloud TMC-1 λ 3 mm wavelength band. recently discovered this species space toward same source at a 8 mm. In those observations, various hyperfine components 0,2 –1 0,1 rotational transition, 37.5 GHz, were detected using Yebes 40 m telescope. Here, we used IRAM 30 telescope to detect ten 5 0,5 –4 0,4 lying 93.6 GHz. The observ...

In retinal detachment surgery, Chawla (I97I) had excellent results using a 7-mm. encircling silastic band, cauterization of the edges of the tear by cryocautery, and evacuation of the subretinal fluid (Schepens, Okamura, and Brockhurst, I957). He felt that the technique was simpler than scleral dissection and safer than the supramid encircling suture. The present study has the following aims: (...
