While studies have examined physical access to services, cognitive and psychosocial barriers to contraceptive use have received less attention, despite their impact on access. Research shows that fours main dimensions exist under the broad concept of cognitive and psychosocial access. This study aims to validate the construction of these dimensions and measure the relation between them and their links with modern contraceptive use. We utilized a questionnaire module to collect 15 questions measuring these dimensions through the 6th round of the Performance monitoring and accountability 2020 (PMA2020) survey in Burkina in 2019. We employed the scale validation technique to choose appropriate measures (observable indicators or items) for constructing each latent dimension (unobservable) in our study. The items consisted of questions that utilized a 5-point Likert scale or dichotomous responses to capture various psychosocial aspects. To assess the validity, reliability, convergence, and divergence of the latent dimensions and items, we utilized the validscale command in Stata. The validation process confirmed the reliability of all the dimensions. Contraceptive approval is more aligned with birth spacing rather than birth limiting, reflecting prevailing social perceptions. Women’s contraceptive agency was found to be more associated with their ability to discuss and negotiate with their partners rather than independent decision-making. Correlations between dimensions were generally weak, but the levels of knowledge, agency, and approval of contraception are positively correlated with contraceptive use and intention to use. Giving women more decision-making power and providing information to address side-effect concerns can enhance contraceptive approval.

For many years, ***1 public database provides biological data relative to the proteome of human umbilical vein endothelial cells (HU-VECs), which are the most used human endothelial cell model in vascular biology. The proteins were identified using two-dimensional gel electrophoresis (2-DGE) for protein separation coupled with Matrix Assisted Laser Desorption-Ionization Mass Spectrometry (MALDI-TOF-MS) for identification. We present here an important update of *** with 521 protein identifications as determined using Fourier transformed ion cyclotron resonance-mass spectrometry (FTICR-MS) applied to an unstained 2-DGE gel cut in 221 squared pieces;each identified protein being accompanied by a semi-quantitative three dimensional visualization is called “score imaging”. The squared analyzed gel and the alphabetical list of identified proteins, linked with their corresponding three-dimensional score imaging, are available at ***. This original approach led to the establishment of the most protein-rich and informative database for HUVECs, as well as to the identification of some protein species, in particular with phosphorylation.

The coordintation of small molecules, like NO, CO or O2, to transition metal phthalocyanines can substantially modify properties of these complexes and their interaction with underlying substrate. We investigated the effect of coadsorption of CO molecules on magnetic properties of manganese phthalocyanines （MnPc） adsorbed on Bi（110） surface. STM experiments reveal a pronounced zero bias anomaly in the tunneling spectra of MnPc, which we attribute to the Kondo effect originating from coupling of molecular magnetic moment to the electrons of the substrate. Bonding of CO to a central metal ion changes the Kondo resonance and leads to the broadening of the zero bias feature. According to DFT calculations, CO-coordination reduces the spin of the complex from 3/2 to 1/2, which explains the increase of the Kondo temperature. The original magnetic state of MnPc is recovered after controlled and selective field-induced desorption of the CO molecules.

形成橡胶-金属复合材料的方法

弹性体 2005年第1期15卷 81-81页

作者： Aganval,RajatK rossier，GreggW 陈大义

将聚合物或其前体(如某种环氧树脂)的薄膜自动地沉积在一活性金属表面上，然后用它做成一种粘结剂，在金属表面和橡胶基质表面之间进行直接粘合，可以得到极强的金属对橡胶的粘结力，既不需要在金属表面涂磷酸酯，也不需用打底漆或粘接剂。
