The method of calculation described is useful for the types of work of which examples are given. It is also useful in making rapid comparison of the activities that might be expected from several different elements. For instance, suppose it is desired to know which of the three elements, cobalt, nickel, or vanadium is, under similar conditions, activated to the greatest extent by thermal neutrons. If reference is made to a cross-section table only, the values may be misleading unless properly interpreted by a suitable comparison of half-lives and abundances. In this table all the variables have been combined and the desired information can be obtained directly from the values ofA 3λ, the activity produced per gram per second of irradiation, under the stated conditions. Hence, it is easily seen that, under similar circumstances of irradiation, vanadium is most easily activated even though the cross section of one of the cobalt isotopes is nearly five times that of vanadium and the cross section of one of the nickel isotopes is three times that of vanadium.

Previous studies had shown that repellent activity was associated with functional groups containing nitrogen and sulfur, and was enhanced by the presence of ionic linkages. Twenty-seven thiouronium compounds and 40 imides, including 1 0 compounds not described previously, were prepared for these tests. Ten imides and 26 thiouronium compounds were repellent under the conditions of test. Information obtained in these studies will be utilized in the development and selection of more effective materials for prevention of rodent damage to foods and other commodities.","language":"English","publisher":"ACS Publications","doi":"10.1021/jf60043a004","usgsCitation":"Bellack, E., and DeWitt, J., 1954, Rodent repellents, preparation and properties of thiouronium compounds and cyclic imides: Journal of Agricultural and Food Chemistry, v. 2, no. 23, p. 1176-1179, https://doi.org/10.1021/jf60043a004.","productDescription":"4 p.","startPage":"1176","endPage":"1179","numberOfPages":"4","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":197840,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","issue":"23","noUsgsAuthors":false,"publicationDate":"2002-05-01","publicationStatus":"PW","scienceBaseUri":"4f4e4aafe4b07f02db66cca7","contributors":{"authors":[{"text":"Bellack, E.","contributorId":78831,"corporation":false,"usgs":true,"family":"Bellack","given":"E.","email":"","affiliations":[],"preferred":false,"id":332509,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"DeWitt, J.B.","contributorId":89080,"corporation":false,"usgs":true,"family":"DeWitt","given":"J.B.","email":"","affiliations":[],"preferred":false,"id":332510,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":5220619,"text":"5220619 - 1954 - Wildlife diseases","interactions":[],"lastModifiedDate":"2012-02-02T00:14:34","indexId":"5220619","displayToPublicDate":"2010-06-16T12:18:22","publicationYear":"1954","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3445,"text":"Southeastern Veterinarian","active":true,"publicationSubtype":{"id":10}},"title":"Wildlife diseases","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Southeastern Veterinarian","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","usgsCitation":"Herman, C.M., 1954, Wildlife diseases: Southeastern Veterinarian, v. 6, no. 1, p. 10-12.","productDescription":"10-12","startPage":"10","endPage":"12","numberOfPages":"3","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":194253,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"6","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48a8e4b07f02db52ad04","contributors":{"authors":[{"text":"Herman, C.
