Interventions for male involvement in pregnancy and labour: A systematic review
No full textMale involvement in pregnancy and labour care has been shown to improve maternal and newborn outcomes. Nevertheless, it continues to be low, especially in low income countries. Several interventions have been suggested for supporting male involvement in reproductive health and maternity care, but no assessment has been made in terms of their effectiveness. The objective of this review was to summarise and evaluate the current evidence related to male partner involvement in maternal health. Three databases were searched electronically. This review included two randomised controlled trials and two observational studies. Two interventions emerged from the review: facility-based couple health education and workplace-based health education. These interventions showed positive outcomes regarding the presence of partners during antenatal visits, postpartum visits, childbirth, and the initiation of breastfeeding within one hour of birth among others. More rigorous research is needed into strategies for, and the effect of, including men in maternal and newborn health

No full textMonte Carlo simulations of mesoscale fracture modelling of concrete with random aggregates and pores
No full textA procedure for generating two-dimensional heterogeneous meso-scale concrete samples is developed, in which the multi-phasic features including the shape, size, volume fraction and spatial distribution of aggregates and pores are randomised. Zero-thickness cohesive interface elements with softening traction–separation relations are pre-inserted within solid element meshes to simulate complex crack initiation and propagation. Extensive Monte Carlo simulations (MCS) of uniaxial tension tests were carried out to investigate the effects of key multi-phasic features on the fracture patterns and load-carrying capacities. It is found that the fracture behaviour and stress-displacement responses of the numerical specimens are highly dependent on the random mesostructures, especially the post-peak softening responses. The specimens fail with either one or two macro-cracks, regardless of the shapes and volume fractions of aggregates and pores. Assuming that the aggregate–mortar interface is weaker than the mortar, using polygonal rather than circular or elliptical aggregates, or increasing the aggregate volume fraction will reduce the tensile strength of specimens. The porosity is found to have severely adverse effects on the specimen strength and cannot be neglected in mesoscale fracture modelling of concrete
Endosymbiotic origin and differential loss of eukaryotic genes
No full textChloroplasts arose from cyanobacteria, mitochondria arose from proteobacteria. Both organelles have conserved their prokaryotic biochemistry, but their genomes are reduced, and most organelle proteins are encoded in the nucleus. Endosymbiotic theory posits that bacterial genes in eukaryotic genomes entered the eukaryotic lineage via organelle ancestors. It predicts episodic influx of prokaryotic genes into the eukaryotic lineage, with acquisition corresponding to endosymbiotic events. Eukaryotic genome sequences, however, increasingly implicate lateral gene transfer, both from prokaryotes to eukaryotes and among eukaryotes, as a source of gene content variation in eukaryotic genomes, which predicts continuous, lineage-specific acquisition of prokaryotic genes in divergent eukaryotic groups. Here we discriminate between these two alternatives by clustering and phylogenetic analysis of eukaryotic gene families having prokaryotic homologues. Our results indicate (1) that gene transfer from bacteria to eukaryotes is episodic, as revealed by gene distributions, and coincides with major evolutionary transitions at the origin of chloroplasts and mitochondria; (2) that gene inheritance in eukaryotes is vertical, as revealed by extensive topological comparison, sparse gene distributions stemming from differential loss; and (3) that continuous, lineage-specific lateral gene transfer, although it sometimes occurs, does not contribute to long-term gene content evolution in eukaryotic genomes
Interim Report: WP2 “Voltage profile modeling and study” Part A and Part B
No full textThis study uses the estimated load models based on literature review and models the capabilty of primary substation to deliver demand response and reactive power absorption capabilty. The model related to primary substation to deliver demand response (Part A) will be validated against the measurements from the Trials. The model related to reactive power absorption capabilty (Part B) will be validated against he IPSA model used in ENWL. The key outcome of Part A is the analysis of the compliance with statutory limits of the network voltages at customers’ premises during voltage regulation techniques. The key outcome of Part B is the analysis that confirms the EHV network reactive power absorption capabilty across ENWL’s network
A Microstructural Study on the Observed Differences in Charpy Impact Behavior Between Hot Isostatically Pressed and Forged 304L and 316L Austenitic Stainless Steel
No full textWith near-net shape technology becoming a more desirable route toward component manufacture due to its ability to reduce machining time and associated costs, it is important to demonstrate that components fabricated via Hot Isostatic Pressing (HIP) are able to perform to similar standards as those set by equivalent forged materials. This paper describes the results of a series of Charpy tests from HIP’d and forged 304L and 316L austenitic stainless steel, and assesses the differences in toughness values observed. The pre-test and post-test microstructures were examined to develop an understanding of the underlying reasons for the differences observed. The as-received microstructure of HIP’d material was found to contain micro-pores, which was not observed in the forged material. In tested specimens, martensite was detectable within close proximity to the fracture surface of Charpy specimens tested at 77 K (−196 °C), and not detected in locations remote from the fracture surface, nor was martensite observed in specimens tested at ambient temperatures. The results suggest that the observed changes in the Charpy toughness are most likely to arise due to differences in as-received microstructures of HIP’d vs forged stainless steel
