Pieces of Iowa’s Past, February 6, 2013

Pieces of Iowa’s Past, published by the Iowa State Capitol Tour Guides weekly during the legislative session, features historical facts about Iowa, the Capitol, and the early workings of state government. All historical publications are reproduced here with the actual spelling, punctuation, and grammar retained. THIS WEEK: Women’s and Children’s Building BACKGROUND: 35TH IOWA GENERAL ASSEMBLY The Thirty-fifth General Assembly convened January 13 and adjourned April 19, 1913—a 97-day session. Edward Cunningham was Speaker of the House and William Harding was the Lieutenant Governor presiding over the Senate. The Senate had 18 Democratic members and 32 Republican members. The House of Representatives had 66 Republican members and 42 Democratic members. There were a total of 158 members in the General Assembly. Governor Beryl Carroll finished his term in January 1913 and Governor George Clarke was sworn in on January 16, 1913. He was 60 years old. The 1910 federal census showed Iowa’s population at 2,224,771.

Deriva nictemeral de macroinvertebrados en el rio Llobregat (Barcelona)

A study on the qualitative and quantitative coniposition of macroinvertebrate drift in the Llobregat river ( N E Spain) is put fonvard. Samples were taken hourly during a 24 hour period in august 1982. The samples were taken with a net of 625 cm. of filtering surface and an opening mesh size of 500 microns, which íiltered 72,1 m3 /h. and collected 75.719 individuals during the sampling period. That means a drift rate of 1.224 indiv./h. and a drift density of 17 indi/m3 . 8 I0/o of the organismes collected were exuviae, mainly pupal chironomid skins (54%) and nimphal ephemeroptera moults (27(Ynj. The remainder percentage of living organisms represents a drift rate of 227 indiv./h. and a drift density of 3.14 indiv./m3. These are intermediate values ifwe compare them with the data published. Sixty per cent of the living drift were chiroiiomids. 17.5 '1 ephemeroptera and 10 (%1 trichoptera; these being the niost iniportant groups. Ofthe 87 species identified in those groups 23 were common in al1 the (7 1 ) samples (Table 1)

ESTUDO DA CARCAÇA DE MACHOS BRAFORD DESMAMADOS AOS 72 OU 210 DIAS, ABATIDOS AOS CATORZE MESES

O objetivo deste trabalho foi comparar as características de carcaça de machos desmamados em duas idades, aos 72 (T72) e aos 210 (T210) dias. Utilizaram-se 36 terneiros 5/8 Hereford e 3/8 Nelore, não castrados, os quais foram terminados em confinamento e abatidos aos 14 meses de idade. Não houve diferença significativa quanto ao peso de fazenda (T72=424 kg e T210=406 kg), rendimento de carcaça quente (T72=54,7% e T210=54,4%), peso de carcaça quente (T72=232 kg e T210=221 kg) e fria (T72=224 kg e T210=214 kg) entre os dois grupos. Os animais desmamados aos 72 dias apresentaram carcaça com conformação ligeiramente superior (11,8 pontos vs. 11,3 pontos) e maior percentagem de costilhar em relação aos novilhos desmamados aos 210 dias, cujos cortes dianteiro e traseiro não diferiram significativamente. Não houve diferença significativa entre as variáveis comprimento de carcaça, comprimento de perna, comprimento de braço, perímetro de braço e espessura de coxão. A espessura de gordura de cobertura não diferiu significativamente entre os dois grupos de carcaça, sendo 4,6 mm e 4,2 mm, respectivamente para T72 e T210 dias. Os resultados mostraram que animais desmamados aos 72 dias de idade apresentam carcaça comparável aos desmamados com 210 dias, com peso e acabamento dentro dos limites exigidos pelos frigoríficos.

Joint inversion of crosshole GPR and seismic traveltime data

Joint inversion of crosshole ground-penetrating radar and seismic data can improve model resolution and fidelity of the resultant individual models. Model coupling obtained by minimizing or penalizing some measure of structural dissimilarity between models appears to be the most versatile approach because only weak assumptions about petrophysical relationships are required. Nevertheless, experimental results and petrophysical arguments suggest that when porosity variations are weak in saturated unconsolidated environments, then radar wave speed is approximately linearly related to seismic wave speed. Under such circumstances, model coupling also can be achieved by incorporating cross-covariances in the model regularization. In two case studies, structural similarity is imposed by penalizing models for which the model cross-gradients are nonzero. A first case study demonstrates improvements in model resolution by comparing the resulting models with borehole information, whereas a second case study uses point-spread functions. Although radar seismic wavespeed crossplots are very similar for the two case studies, the models plot in different portions of the graph, suggesting variances in porosity. Both examples display a close, quasilinear relationship between radar seismic wave speed in unconsolidated environments that is described rather well by the corresponding lower Hashin-Shtrikman (HS) bounds. Combining crossplots of the joint inversion models with HS bounds can constrain porosity and pore structure better than individual inversion results can.

Exploring the periodicity of cardiovascular events in Switzerland: variation in deaths and hospitalizations across seasons, day of the week and hour of the day.

PURPOSE: The purpose of this study is to explore the periodical patterns of events and deaths related to cardiovascular disease (CVD), acute myocardial infarction (AMI) and stroke in Swiss adults (≥ 18 years). METHODS: Mortality data for period 1969-2007 (N=869,863 CVD events) and hospitalization data for period 1997-2008 (N=959,990 CVD events) were used. The annual, weekly and circadian distribution of CVD-related deaths and events were assessed. Multivariate analysis was conducted using multinomial logistic regression adjusting for age, gender and calendar year and considering deaths from respiratory diseases, accidents or other causes as competitive events. RESULTS: CVD deaths and hospitalizations occurred less frequently in the summer months. Similar patterns were found for AMI and stroke. No significant weekly variation for CVD deaths was found. Stratification by age and gender showed subjects aged <65 years to present a higher probability of dying on Mondays and Saturday, only for men. This finding was confirmed after multivariate adjustment. Finally, a circadian variation in CVD mortality was observed, with a first peak in the morning (8-12 am) and a smaller second peak in the late afternoon (2-6 pm). This pattern persisted after multivariate adjustment and was more pronounced for AMI than for stroke. CONCLUSION: There is a periodicity of hospitalizations and deaths related to CVD, AMI and stroke in Switzerland. This pattern changes slightly according to the age and sex of the subjects. Although the underlying mechanisms are not fully identified, preventive measures should take into account these aspects to develop better strategies of prevention and management of CVD.
