I127(3He,t)127Xe reaction with relevance to neutrino detection

The I127(3He,t)127Xe reaction has been measured for low-lying states in Xe127 which may play a role in neutrino capture by I127. High-spin states at excitation energies Ex=309 and 646 keV are found to be much more strongly populated than the Jπ=((3/2-(7/2)+ states relevant to neutrino capture by I127

Astronomical Distance Determination in the Space Age: Secondary Distance Indicators

The formal division of the distance indicators into primary and secondary leads to difficulties in description of methods which can actually be used in two ways: with, and without the support of the other methods for scaling. Thus instead of concentrating on the scaling requirement we concentrate on all methods of distance determination to extragalactic sources which are designated, at least formally, to use for individual sources. Among those, the Supernovae Ia is clearly the leader due to its enormous success in determination of the expansion rate of the Universe. However, new methods are rapidly developing, and there is also a progress in more traditional methods. We give a general overview of the methods but we mostly concentrate on the most recent developments in each field, and future expectations. © 2018, The Author(s)

Does the offer of cervical screening with breast screening encourage older women to have a cervical smear test?

OBJECTIVE--The aim was to determine what effect the offer of a cervical smear test when attending for breast screening has on the uptake of cervical and breast screening. DESIGN--The study involved randomisation to compare uptake in those women invited for cervical screening in advance with their breast screening invitation (group 1) with those invited for breast screening only and then offered a smear test upon arrival for breast screening (group 2). The main outcome measure was improvement in the uptake of cervical screening among older women without detriment to the breast screening service. SETTING--The study took place at the Northern Hospital in North Manchester. PARTICIPANTS--Participants were 2131 women aged 50-64 years invited for breast screening at the Northern Hospital in the summer of 1990. MAIN RESULTS--Overall, 54% of the women who were eligible attended for breast screening, 52% attended from group 1 and 55% from group 2. Of those attending for breast screening, 957 were eligible for cervical screening and 193 (20%) had a smear test. There was a difference in the proportion tested from each group (p < 0.001), 28% had a smear test from group 1 and 13% from group 2. Forty five percent of the 193 had not had a cervical smear for at least five years. CONCLUSIONS--The cervical screening facility did attract some women who were overdue for a smear test and who might not normally have attended for cervical screening, and there was no evidence to suggest that it had a detrimental effect on the breast screening uptake. An advanced cervical screening invitation seemed preferable to an invitation upon arrival at the breast screening unit

Fatores de correção para perímetro escrotal ao sobreano para tourinhos mestiços Aberdeen Angus x Nelore Adjustment factors for scrotal circumference at yearling for crossbred Aberdeen Angus x Nelore young bulls

Obtiveram-se fatores de correção (FC) para o perímetro escrotal ao sobreano (PES) para os efeitos de grupo genético (GG), heterozigose individual (HI), peso ao sobreano (PS) e idade do animal à pesagem de sobreano (IDS), utilizando-se registros de peso corporal e medidas de perímetro escrotal obtidos de 11.662 tourinhos das raças Aberdeen Angus, Nelore e de produtos do cruzamento entre elas, criados nas regiões Sul, Sudeste e Centro-Oeste do Brasil, nascidos entre 1987 e 2001. Os coeficientes de regressão que geraram os FC foram estimados pelo método dos quadrados mínimos, adotando um modelo que incluiu os efeitos de grupo de contemporâneos ao sobreano (GC), GG, heterozigose materna (HM), HI, PS e IDS. Todos os efeitos incluídos no modelo foram significativos (P<0,01) sobre PES. A média observada e respectivo desvio-padrão para PES foi 29,90±3,55cm. Foi observado efeito polinomial de segunda ordem de PS sobre PES. Foram verificados ganhos decrescentes no PES à medida que o POS aumentou, ou seja, os maiores acréscimos foram observados em animais recém desmamados. O efeito linear de PS sobre PES foi 0,06695804±0,00345000cm/kg, e o efeito quadrático, 0,00005252±0,00000508cm/kg². Para IDS o efeito linear foi de 0,02176450±0,00038568cm/dia. Aumentos de HI e HM promoveram incremento no PES e de GG, decréscimos. Os fatores incluídos no modelo foram importantes fontes de variação que devem ser considerados no ajuste de PES para seleção de tourinhos para melhora da precocidade sexual.<br>Adjustment factors (AF) for scrotal circumference at yearling (SCY) were figured out for effects of genetic group (GG), individual heterozygosis (IH), yearling weight (YW), and age of the animal at yearling weight (AYW) using body weight and scrotal circumference records from 11,662 Aberdeen Angus, Nelore, and their crosses. The animals were born from 1987 to 2001 and were raised in the South East and Central West Regions of Brazil. The regression coefficients to obtain AF were estimated by least squares means method. The model included the fixed effects of contemporaneous group at yearling (CG), maternal heterozygosis (MH), IH, and the covariates YW (linear and quadratic effects) and AYW (linear effect). All the factors included in the model showed significant effects (P<0.01) on SCY. The mean and standard deviation for SCY were 29.90±3.55cm. Quadratic effect of YW on SCY was also observed. Decreases in SCY with the increase in YW was found. High SCY was observed immediately after post-weaning. The YW effects on SCY were 0.06695804±0.00345000cm/kg (linear effect) and -0.00005252±0.00000508cm/kg² (quadratic effect). The AYW linear effect on SCY was 0.02176450±0.00038568cm/day. The factors included in the model are important sources of variation to adjust SCY for the selection of young bulls in order to improve sexual precocity
