Under the entrywise dominance partial ordering, T.L. Markham and R.L. Smith obtained a Schur complement inequality for the Hadamard product of two tridiagonal totally nonnegative matrices. Applying the properties of the Hadamard core of totally nonnegative matrices, the Schur complement inequalities for the Hadamard product of totally nonnegative matrices is obtained, which extends those of T.L...

Historically, Canadian family physicians have operated out of their own clinics, providing excellent primary care to patients who come through the front doors. More recently, health care delivery has moved away from older models of paternalistic, physiciancentred care and toward patient-centred care. At the same time, there are ongoing efforts to maximize efficiency in our resource-limited heal...

Approximately 3.2 to 3.5 million metric tonnes of DDGS are produced annually in North America (Markham, 2000; personal communication). Ethanol plants in Minnesota, South Dakota and North Dakota produce approximately 25% of this amount (850,000 to 900,000 tonnes) annually (Markham, 2000; personal communication). Most of the ethanol plants in the Minnesota-Dakota (MNDAK) region are small, farmer ...

Our knowledge of the structure of ribonucleic acids (RNA) has advanced considerably in recent years. In the first place, the refinement of chromatographic techniques has made possible an accurate estimation of the purine and pyrimidine composition (Vischer & Chargaff, 1948; Markham & Smith, 1949; Carter, 1950; Markham & Smith, 1951). Secondly, with the aid of both chemical and enzymic methods i...
