Exercise Beliefs During Pregnancy in a Predominantly Low-Income, Urban Minority Population
In 2002, and reaffirmed in 2009, The American College of Obstetricians and Gynecologists recommended that healthy pregnant women exercise for at least thirty minutes most days of the week. Exercise during a healthy pregnancy is safe and has many maternal and fetal benefits. Identified benefits include management of weight gain, improvement in mood, and preparation for labor. Previous research has evaluated women’s beliefs and practices of exercise in pregnancy, but it has focused on affluent, ethnic majority populations. This survey study was performed to assess beliefs about exercise in pregnancy in a predominantly low-income, urban minority population.https://jdc.jefferson.edu/cwicposters/1031/thumbnail.jp

Pengaruh Kontrasepsi Hormonal Planibu® Versus Depo Progestin® terhadap Fungsi Hepar dan Profil Lipid
Background: Injectable contraception was used by about 15% of contraceptive users in Indonesia. Safety of injectable contraceptive was necessary to study before Planibu® was marketed in Indonesia. Safety was measured through liver function and lipid profile parameters.Objectives: To compare safety of Planibu® versus Depo Progestin® that was measured with liver function and lipid profile parameters Design of Study: “Double Blind Randomized Controlled Trial (Double Blind RCT)” Planibu® versus Depo Progestin®” nested on longitudinal surveillance and community based study in Purworejo district (LPKGM centre) and Manado municipality (Manado centre)Methods: Study population was childbearing age women, married and wanted to delay or space pregnancy with injectable contraceptive in Purworejo district and Manado municipality. Clinical, gynecological and laboratory examination was done before injectable contraceptive was administered. Laboratory examination included liver function SGOT, SGPT and lipid profile HDL, LDL and total cholesterol. Eligible Subjects who met inclusion and exclusion criteria were 70 women. As many as 35 women received Planibu® injection and 35 women received Depo Progestin® injection every 3 months for 12 months in the same time. Before injection was administered, venous blood sampling was taken from each subject.Results: Before using contraception, there was no statistical difference of liver function and lipid profile parameters between group Planibu® and Depo Progestin® (p>0,05). There was a statistically significant difference in the level of cholesterol, HDL, and SGOT during the 12 month of use Depo Progestin® (p=0,000, p=0,009 and p=0,000), although clinically it wasn't significantly different. There was a statistically significant difference in the level of cholesterol, SGOT and SGPT during the 12 month of use Planibu® (p =0,038, p=0,000 dan p=0,018), although clinically it wasn't significantly different. There was a statistically significant difference in the level of cholesterol and LDL during the 12 month of use Planibu® versus Depo Progestin® (p<0,05)Conclusion: There was a statistically significant difference in the level of cholesterol, HDL, and SGOT during the 12 month of use Depo Progestin®, although clinically it wasn't significantly different. There was a statistically significant difference in the level of cholesterol, SGOT and SGPT during the 12 month of use Planibu®, although clinically it wasn't significantly different. There was a statistically significant difference in the level of cholesterol and LDL during the 12 month of use Planibu® versus Depo Progestin®, although clinically it wasn't significantly different. There was no difference clinically in the safety level of Planibu® versus Depo Progestin® shown by measurement result of liver function and lipid profile parameters
Adubação nitrogenada totalmente na semeadura do trigo.
Os triticultores dispõem de considerável volume de informações para definir a dose de N a ser minitrada na lavoura, contudo, tem havido pouco questionamento sobre o modo de aplicação do fertilizante nitrogenado. O trabalho teve por objetivo avaliar as fontes uréia, uréia+NBPT (inibidor de urease) e nitrato de amônio em diferentes doses aplicadas nos sulcos de semeadura do trigo, em comparação com a adubação de cobertura, em duas condições de cultivo, em regime de sequeiro e irrigado. Foram realizados dois experimentos na safra de 2011, em Ponta Grossa/PR em regime de sequeiro e solo de textura média, e em Londrina/PR com irrigação e solo argiloso, localidades representativas das macrorregiões tritícolas I e III do Paraná, respectivamente. O nitrato de amônio é a fonte mais segura para uso em adubos formulados NPK para a semeadura do trigo. A uréia nos sulcos de semeadura causa forte fitoxicidade à lavoura de trigo, e o inibidor de urease NBPT minimiza tal impacto. A adubação nitrogenada na semeadura do trigo deve contemplar doses de 20 a 40 kg N ha-1. O modo de aplicação do N no trigo, semeadura e/ou cobertura, guarda forte interação com o ambiente de cultivo.Fertbio
Fire analysis of steel frames with the use of artificial neural networks
The paper presents an alternative approach to the modelling of the mechanical behaviour of steel frame material when exposed to the high temperatures expected in fires. Based on a series of stress-strain curves obtained experimentally for various temperature levels, an artificial neural network (ANN) is employed in the material modelling of steel. Geometrically and materially, a non-linear analysis of plane frame structures subjected to fire is performed by FEM. The numerical results of a simply supported beam are compared with our measurements, and show a good agreement, although the temperature-displacement curves exhibit rather irregular shapes. It can be concluded that ANN is an efficient tool for modelling the material properties of steel frames in fire engineering design studies. (c) 2007 Elsevier Ltd. All rights reserved
Models for Light-Cone Meson Distribution Amplitudes
Leading-twist distribution amplitudes (DAs) of light mesons like pi,rho etc.
describe the leading nonperturbative hadronic contributions to exclusive QCD
reactions at large energy transfer, for instance electromagnetic form factors.
They also enter B decay amplitudes described in QCD factorisation, in
particular nonleptonic two-body decays. Being nonperturbative quantities, DAs
cannot be calculated from first principles, but have to be described by models.
Most models for DAs rely on a fixed order conformal expansion, which is
strictly valid for large factorisation scales, but not always sufficient in
phenomenological applications. We derive models for DAs that are valid to all
orders in the conformal expansion and characterised by a small number of
parameters which are related to experimental observables.Comment: 19 pages, 10 figure
Shake-induced order in nanosphere systems
Self-assembled patterns obtained from a drying nanosphere suspension are
investigated by computer simulations and simple experiments. Motivated by the
earlier experimental results of Sasaki and Hane and Schope, we confirm that
more ordered triangular lattice structures can be obtained whenever a moderate
intensity random shaking is applied on the drying system. Computer simulations
are realized on an improved version of a recently elaborated
Burridge-Knopoff-type model. Experiments are made following the setup of Sasaki
and Hane, using ultrasonic radiation as source for controlled shaking.Comment: 7 pages, 10 figure
