An Investigation of the "Trial" Stage in the Adoption Process: Aerial Topdressing in the Clarence Valley AgEcon
Duncan, Ronald C..
Sociological studies have tended to concentrate on the awareness stage in the adoption process to the neglect of the remaining stages. In an attempt to examine the role of the trial stage in the adoption of super-phosphate topdressings in the Clarence Valley, a survey was made of 42 farmers. From the history of superphosphate use on each farm, a distinction between trial and immediate adoption is attempted. It is concluded that as the farming practice becomes more widely used, the initial farm area fertilized increases, the change from trial to adoption accelerates, and the need for a trial stage appears to diminish.

The national agricultural policies and their impact on Nigeria’s agriculture were highlighted emphasizing the previous and present roles of various organs of the government. After discussing the assets and liabilities of Nigeria’s agriculture, the paper posits that the agricultural environment must be properly managed for sustainable agricultural productivity in view of emerging information technology. The future expectations and challenges facing the Nigerian agricultural engineers,...

Analyse chimique continue de la mer: II. Mission internationale <i>Mechelen</i> 1968 en Méditerranée OMA
Ballester, A.; Cruzado, A.; Macchi, G..
Results of automatic and continuous analysis of both physical and chemical parameters of sea water between Marbella (Malaga) and Brest (<i>Mechelen</i> cruise, Mediterranean 1968, supported by the « Institut royal des Sciences naturelles de Belgique ») are studied in this paper.Two conclusions are reached: 1° The distribution of salinity, temperature and nitrate, sometimes anomalous, appears to follow some rythm or law. 2° There appears a close spacial relationship too between these anomalies and fishery. Then, it is possible to use the continuous automatic method for the exploratory work on fishery technology.

Analysis of Selected Tractor Seats for Seating Dimensions in Laboratory CIGR Journal
K. K. Jain; A. K. Shrivastava; C. R. Mehta.
Tractor seat is one of the important component / assembly as far as the human machine system and comfort of tractor operator are concerned .With this in view, a field survey and laboratory study were conducted of selected popular tractors and tractor seats, respectively, with particular reference to seating dimensions. Dimensions for seat pan and backrest were measured and analyzed, according to BIS recommendations. The results highlighted that seat pan width was found 10.9% less, seat height was found 15.3% in excess, no vertical adjustments and backrest width was also found 20.4% less. This may cause discomfort for smaller as well as higher percentile tractor operators. Based upon the design of mounting arrangement of different tractor seats – a common...

Anomalies in the dentition of the Fox, Vulpes vulpes (Linnaeus, 1758), from continental western Europe Naturalis
Bree, P.J.H. van; Sinkeldam, E.J..
While studying skulls of Foxes from western Europe for taxonomical purposes, the authors were struck by the high percentage of skulls not showing the normal tooth-formula. However, after a literature survey, it became clear this phenomenon is not rare in Canidae (Colyer, 1936; Hall, 1940; Reinwaldt, 1963, and Fleischer, 1967). But the occurrence of anomalies in the dentition may vary geographically and as such may have taxonomical significance (e.g., in Talpa europaea; see Stein, 1963). Thus it was thought useful to publish our data. Our notes concern samples from three different populations, viz., from the Netherlands, from western France (roughly the area between Rennes and Bordeaux) and from southern France (southeastern slopes of the Cevennes). For the...
