The possible role of weed races in the evolution of cultivated plants

Abstract: Most of our cultivated plants have companion weed races. This phenomenon is so common that it must have some biological significance. In some cases the weeds are the progenitors of the crops, but in many cases we must look for something that could give rise to both the weed forms and the cultivated form together.

Measurement of inclusive jet and dijet cross sections in proton-proton collisions at 7 TeV centre-of-mass energy with the ATLAS detector

Abstract: Jet cross sections have been measured for the first time in proton-proton collisions at a centre-of-mass energy of 7 TeV using the ATLAS detector. The measurement uses an integrated luminosity of 17 nb-1 recorded at the Large Hadron Collider. The anti-kt algorithm is used to identify jets, with two jet resolution parameters, R = 0.4 and 0.6. The dominant uncertainty comes from the jet energy scale, which is determined to within 7% for central jets above 60 GeV transverse momentum. Inclusive single-jet differential cross sections are presented as functions of jet transverse momentum and rapidity. Dijet cross sections are presented as functions of dijet mass and the angular variable $\chi$. The results are compared to expectations based on next-to-leading-order QCD, which agree with the data, providing a validation of the theory in a new kinematic regime.

Nucleation and Growth of Colloidal Crystals

Abstract: bcc crystalline colloidal microsphere suspensions are shear melted into the metastable liquid phase. Recrystallization occurs via nucleation and growth of single crystallites at dilute sites. The nearly spherical growing crystals have rough interfaces with a time-independent interface velocity, $v$. The velocity is found to be consistent with an equation for normal growth with a limiting velocity determined by free-particle diffusion, ${v}_{0}\ensuremath{\sim}\frac{{D}_{0}}{\ensuremath{\xi}}$, where ${D}_{0}$ is the Stokes diffusion constant of independent noninteracting spheres, and $\ensuremath{\xi}$ is a length comparable to the particle spacing.

Equine Pituitary Pars Intermedia Dysfunction

Abstract: Equine pituitary pars intermedia dysfunction (PPID), also known as equine Cushing's syndrome, is a widely recognized disease of aged horses. Over the past two decades, the aged horse population has expanded significantly and in addition, client awareness of PPID has increased. As a result, there has been an increase in both diagnostic testing and treatment of the disease. This review focuses on the pathophysiology and clinical syndrome, as well as advances in diagnostic testing and treatment of PPID, with an emphasis on those findings that are new since the excellent comprehensive review by Schott in 2002.

The fashion‐conscious behaviours of mature female consumers

Abstract: Under-appreciation of mature consumers as a numerous and comparatively wealthy market segment has resulted in not only lost revenues for business, but also lost consumption and service opportunities for the elderly. In response to expressed needs for more research into actual and desired consumption by older consumers, this study examined the apparel and shopping preferences of mature women in America. Independent living residents were surveyed concerning fashion consciousness, fashion information sources and shopping behaviours. Young and mature consumers’ reactions to female apparel ensembles were compared. Mature subjects purchased apparel for pleasure or need, but less for conformity. Decisions were influenced more by fit and comfort than by fashion, despite suggestions that dressing stylishly was important. New fashions were encountered via catalogue illustrations, social gatherings and window displays. Subjects high in fashion consciousness had greater financial and social involvement with fashion, greater chronological-to-cognitive age differences and larger clothing budgets. Young and mature consumers’ responses to apparel illustrations differed significantly. As the mature market expands, attention to age-divergent definitions of fashion (such as those based upon admiration of comfort) will determine the success of apparel businesses. Assessment of cognitive age will facilitate identification of those mature consumers most predisposed toward fashion consumption.
