A New Kimballian Peccary From Nebraska, C. Bertrand Schultz, Larry D. Martin
A New Kimballian Peccary From Nebraska, C. Bertrand Schultz, Larry D. Martin
Bulletin of the University of Nebraska State Museum (1924–2023)
A new species of Pliocene peccary, Prosthennops (Macrogens) graffhami; is described from the Kimball Formation, Ogallala Group, Frontier County, Nebraska. This new species is the latest in geologic age and most advanced in the genus.
The remains of fossil vertebrates are generally rare in the upper part of the Ogallala group, and some have maintained that Hemphillian faunas such as Coffee Ranch and Smith County, Kansas, represent the latest Ogallala faunas. Later faunas than are typically considered as Hemphillian, containing more advanced forms, occur in the Kimball Formation and deposits of equivalent age. Known faunas which may …

Bears (Ursidae) From The Late Cenozoic Of Nebraska, C. Bertrand Schultz, Larry D. Martin
Bulletin of the University of Nebraska State Museum (1924–2023)
A ramus and partial premaxilla establish the presence of a new subspecies of Indarctos in the upper Pliocene (Kimball Formation, Ogallala Group) of Frontier County, Nebraska. An extremely large species of Agriotherium is represented by fragmentary remains from the middle Pliocene (middle part of Ash Hollow Formation, Ogallala Group) of Sherman County, Nebraska.
This study is part of a series of papers dealing primarily with the fauna of the Kimball formation in Nebraska (Barbour 1927, 1929; Barbour and Schultz, 1941; Schultz and Stout, 1948, 1961; Kent 1963, 1967; Tanner, 1967; Short, 1969; Martin and Tate, 1970; Schultz, Schultz, and Martin, …

Scimitar-Toothed Cats, Machairodus And Nimravides, From The Pliocene Of Kansas And Nebraska, Larry D. Martin, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
"Machairodus catocopis Cope" is shown to be a pseudaelurin cat belonging to the genus Nimravides Kitts. Nimravides thinobates (Macdonald) is a possible synonym of N. catocopis (Cope). Nimravides is compared with the Eurasian Machairodus-like cat, Dinofelis. Machairodus (Heterofelis) coloradensis is reported from the Kimball Formation, upper Pliocene (Kimballian) of Cheyenne County, Nebraska, and from the upper part of the Ash Hollow Formation, Pliocene (Hemphillian) of Sherman County, Nebraska. The Kimballian form is described as a new subspecies, Machairodus coloradensis tanneri.
The genus Machairodus has long been associated with the Hemphillian of North America and the …

Summary Of Trial Results - 1974, N R. Mckeown
Experimental Summaries - Plant Research
Observations and measurements were made on 10 grazing trials and 11 small-plot legume species trials in 1974. Three of the grazing trials were under crop, two of them concluding low oestrogen species trials which had been grazed since 1969, and one of them, 68M023, West Moora, as an interval between pasture phases. The small-plot trials dated from 1970 or later and on most of them half of each plot could be grazed by sheep and half was protected. These trials have continued to supply useful information on the suitabiliy of cultivars to soil and climate and will be the subject …
Electrochemical Machining (Ecm) With Alternating Current, S. J. Shine
Electrochemical Machining (Ecm) With Alternating Current, S. J. Shine
Tanzania Journal of Science
Electrochemistry has had several practical uses in industry for a long time; but one of the more recent applications is the machining of metals. Direct current ECM has been applied in industry for the last two decades. However, ECM with alternating current is still in the early stage of research and development. This paper shows that ECM with normal a.c supply is feasible and practicable if special tools are used. ECM with d.c. is first introduced to provide a better insight for the machining with a.c.

The Kunduchi Mangrove Basin, Alison Mccusker
The Kunduchi Mangrove Basin, Alison Mccusker
Tanzania Journal of Science
The pattern of tidal submergence and exposure in the Kunduchi mangrove basin is determined by contour mapping and by relating the contours to published tide predictions. Salinity of the creek effluent is measured at spring and neap tides in both wet and dry seasons. The vegetation of the basin, up to the highest high water level, is described briefly.

Fisheries Report No 19 - The Western Rock Lobster Fishery 1973 - 1974, G. R. Morgan, E H. Barker
Fisheries Report No 19 - The Western Rock Lobster Fishery 1973 - 1974, G. R. Morgan, E H. Barker
Fisheries Research Reports
The fishery for the western rock lobster* is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. Inherent …
