The present work aimed to evaluate, through ten different studies, the therapeutic efficacy of a new pour-on formulation, containing 1.5 per cent ivermectin +0.5 per cent abamectin, against parasites of cattle. Results obtained on trials against Rhipicephalus (Boophilus) microplus showed that the pour-on combination of 1.5 per cent ivermectin +0.5 per cent abamectin obtained superior efficacy i...

When I had the pleasure of visiting the Cosmotron at Brookhaven in 1956 I took some statistics on the conversations in the hall. I found that 10 per cent was small talk, 25 pe, cent was about physics, and 65 per cent was about Scheduling. T’lese percen ages uive 3’. indication that even at that time the social problems of high-energy physics appeared to take precedence over the subject itself, ...

1. Passive steel wires were activated in a bath (Bath A) containing 70 v. per cent HNO(3) (in which they undergo prompt repassivation), and immediately transferred to a second bath (Bath B) containing HNO(3) of a concentration varying in different experiments. After varying intervals in this bath they were transferred while still passive to a third bath (Bath C) containing strong HNO(3) (70 or ...

We estimated the diagnostic skill of clinicians managing melanocytic skin naevi by measuring the percentage of malignant melanomas, premalignant and potentially malignant naevi, in 1896 excised melanocytic lesions submitted to a pathology service over 11 weeks. They comprised 8 per cent. The percentage increased with age: 4 per cent in the under-40s, 17 per cent in those aged 40-59, and 30 per ...

Although the presence of leukemic infiltrate in isolated organs of patie~ts \\'ith chronic lymphocytic leukemia has been reported. the effects of leukemic infiltration into v!rious organs of such patients have never been comprehensively studied. To determine the effects of leukemic infiltration \ve reviewed the histologic sections of multiple organs in 47 cases of chronic lymphocytic leukemia a...

Impacts from a changing climate, in particular sea-level rise, will be most acutely felt on small oceanic islands. A common configuration of mid-latitude islands is the sandy barrier island. Sable Island, Nova Scotia, Canada vegetated sand island near shelf edge, 160 km nearest point land, that morphologically similar to This study uses 60 years airphoto records analyse changes coastline positi...

P ERIODIC REPORTS HAVE EMPHASIZED the lack of stability of repeated tuberCulin skin tests in children. Kunofsky and Katz1 reported on two large groups in two schools for mental defectives. Reversion rates of 4 to 19 per cent were found. Marks et al.2 reported reversion rates between 12 and 26 per cent, depending on Criteria used, during a one-year period of observation of 1,100 tuberculin posit...
