Abundant chaos in a mixer model with a hysteretic iron core inductance.

Industrial mixers are equipment used in food, drug, chemical and semiconductor industries. Chaotic mixing has been proposed to improve the degree of homogeneity and reduce the energy consumption. This paper deals with dynamical studies of a mixer model with complex rotational movements.

Postabortion care availability, readiness, and accessibility in Niger in 2022: results from linked facility-female cross-sectional data.

Background: Postabortion care (PAC), which is an essential element of emergency obstetric care, is underresearched in Niger. The study aims to assess the availability, readiness, and accessibility of facility-based PAC services in Niger.

Methods: This study uses female and facility data from Performance Monitoring for Action Niger.

Abortion incidence and safety in Niger in 2021: Findings from a nationally representative cross-sectional survey of reproductive-aged women using direct and indirect measurement approaches.

Niger is a country in which legal restrictions and a dearth of research has long limited our understanding of the extent and safety of induced abortion. The current study is the first national study of induced abortion in Niger. It uses direct (self-report) and indirect (best friend method) to provide nationally representative estimates of induced abortion incidence and safety and evaluates the performance of the indirect measurement approach.

Selection of new sweetpotato hybrids for West Africa using accelerated breeding scheme and genotype × environment interaction under drought stress.

West Africa is a dry region and drought tolerant sweetpotato cultivar was not reported. The objective of this study was to develop higher yielding drought tolerant sweetpotato hybrids following accelerated breeding scheme (ABS), and study G × E interaction. During advanced yield trial, the assessment of clones was conducted in six locations: four in Niger and two in Nigeria.
