Contraceptive Methods Accessed in Volta Region, Ghana, 2009–2014

INTRODUCTION In 2016, Volta Region was one of the two regions in Ghana that recorded a high prevalence of teenage pregnancy, accounting for 15.5% of all adolescent pregnancies in the country. This study aimed to determine the prevalence of contraceptive methods accessed by person, place, and time in Volta Region, Ghana, 2009-2014. METHOD We carried out a secondary analysis of contraceptive us...

Integration in the Glowa Volta Project: from Concept to Feasibility

Integration in the GLOWA Volta project is a means to an end. The end is to establish a decision support system (DSS) for water management that is scientifically sound and can be readily used by decision makers in the region in order to optimize water allocation between regions and sectors. Economic, social and natural science issues will have to be brought into the analysis. The GLOWA Volta pro...

Cryo-EM single particle analysis with the Volta phase plate.

We present a method for in-focus data acquisition with a phase plate that enables near-atomic resolution single particle reconstructions. Accurate focusing is the determining factor for obtaining high quality data. A double-area focusing strategy was implemented in order to achieve the required precision. With this approach we obtained a 3.2 Å resolution reconstruction of the Thermoplasma acido...

Using the Volta phase plate with defocus for cryo-EM single particle analysis

Previously, we reported an in-focus data acquisition method for cryo-EM single-particle analysis with the Volta phase plate (Danev and Baumeister, 2016). Here, we extend the technique to include a small amount of defocus which enables contrast transfer function measurement and correction. This hybrid approach simplifies the experiment and increases the data acquisition speed. It also removes th...
