OBJECTIVES The purpose of this paper is to examine whether the elevated rate of low birth weight (LBW) in the Region of Peel, Ontario can be attributed to the high proportion of immigrants in the population. In addition, we examined how the infant birth weight distribution in Peel differs by maternal region of birth. METHODS Provincial live birth registration data were used to compare rates o...

Principal component analysis (PCA) is a ubiquitous method of multivariate statistics that focuses on the eigenvalues lambda and eigenvectors of the sample covariance matrix of a data set. We consider p, N-dimensional data vectors xi drawn from a distribution with covariance matrix C. We use the replica method to evaluate the expected eigenvalue distribution rho(lambda) as N--> infinity with p=a...

The growth of Salmonella typhimurium (ATCC 14028) on the surface of autoclaved ground chicken breast and thigh burgers incubated at constant temperatures from 8 to 48 degrees C in 2 degrees C increments was investigated and modeled. Growth curves at each temperature were fit to a two-phase linear primary model to determine lag time (lambda) and specific growth rate (mu). Growth of S. typhimuriu...

A method is formulated for the description of lambda hypernuclei in the framework of the unitary-model-operator approach (UMOA). The method is applied to 17 Λ O. A lambda-nucleon effective interaction is derived, taking the coupling of the sigma-nucleon channel into account. The lambda single-particle energies are calculated for the 0s1/2, 0p3/2 and 0p1/2 states employing the Nijmegen soft-core...

The lambda single-particle energies are calculated for the 0s1/2, 0p3/2 and 0p1/2 states employing the Nijmegen soft-core (NSC), Jülich model-Ã (J...

As you go through life, you reflect on your choices. Donna Gray ‘90 smiles in hindsight, knowing those choices created the best possible journey for her life. When she walked across the campus of Millersville University with her older sister Denise Draper-Chandler '80, she immediately knew she would follow in her footsteps and attend Millersville. The next major decision to impact her life at M...

OBJECTIVE To establish reference growth charts for Saudi children and adolescents. METHODS Multi-stage probability sampling of a cross-section of Saudi children and adolescents residing in all 13 regions of the Kingdom. Family interviews, and physical examinations of children and adolescents from birth to 19 years of age were conducted over a 2-year period (2004-2005). Only healthy children a...

The murine pre-B cell-specific genes VpreB and lambda 5, as well as the murine gene for mu heavy chain, were introduced into Ltk- fibroblast cells which normally do not express these genes. Stable transfectants carrying these genes produced the corresponding proteins of 15.5, 21.5, and 75 kD. They secreted the three proteins as a triple complex that could be immunoprecipitated by mu heavy chain...
