Introduction Reproduction efficiency of the herd is optimal when replacement heifers attain puberty as yearlings and calve at 2 years of age, and cows are able to become pregnant early during the annual breeding season (Bagley, 1993). Nutrition is the environmental factor that most influences reproductive efficiency of cattle (Bagley, 1993; Diskin et al., 2003); therefore, beef females should b...

in this paper the bagley-torvik equation as a prototype fractional differential equation with two derivatives is investigated by means of homotopy perturbation method. the results reveal that the present method is very effective and accurate.

A polynomial near-ring can mean one of several things. Here a polynomial near-ring is a near-ring of polynomials with the coefficients from a near-ring in the sense of van der Walt and Bagley. We describe quotients of such polynomial near-rings by principal ideals leading to generalizations of some well-known ring constructions. MSC 2000: 16Y30

The paper critically reflects on data derived from prolonged periods of ethnographic study in an economically disadvantaged white workingclass rural community the North East England. A central aim was to understand culture village and capture penetrate social relationships meanings within that as understood by its inhabitants their relationship with local school (see Bagley Hillyard, 2013, 2015...
