Exclusive breastfeeding is the provision of breast milk without other additional food. This study aims to determine the factors associated with the practice of exclusive breastfeeding in infants aged 0 - 6 months at the Rada Mata Public Health Center, Southwest Sumba Regency, which was conducted from August to October 2020. This type of research was an analytical observational with cross-sectional study. Sampling in this study were 75 respondents who had children aged 6-12 months. Data processing was carried out descriptively and analytically. The results showed a significant relationship between education, knowledge, employment, support from health workers, family support for exclusive breastfeeding for infants 0-6 months at the Rada Mata Puskesmas, Southwest Sumba Regency. Mothers who have a good education have the opportunity to provide exclusive breastfeeding for their babies, as well as work, support from health workers and family support for mothers under five. Therefore, it is necessary to collaborate between health workers and the local community, especially mothers who have babies aged 0 - 6 months so that the program can be implemented properly

Single Color Centers Implanted in Diamond Nanostructures

The development of materials processing techniques for optical diamond nanostructures containing a single color center is an important problem in quantum science and technology. In this work, we present the combination of ion implantation and top-down diamond nanofabrication in two scenarios: diamond nanopillars and diamond nanowires. The first device consists of a 'shallow' implant (~20nm) to generate Nitrogen-vacancy (NV) color centers near the top surface of the diamond crystal. Individual NV centers are then isolated mechanically by dry etching a regular array of nanopillars in the diamond surface. Photon anti-bunching measurements indicate that a high yield (>10%) of the devices contain a single NV center. The second device demonstrates 'deep' (~1\mu m) implantation of individual NV centers into pre-fabricated diamond nanowire. The high single photon flux of the nanowire geometry, combined with the low background fluorescence of the ultrapure diamond, allows us to sustain strong photon anti-bunching even at high pump powers.Comment: 20 pages, 7 figure

Enhanced Single Photon Emission from a Diamond-Silver Aperture

We have developed a scalable method for coupling single color centers in diamond to plasmonic resonators and demonstrated Purcell enhancement of the single photon emission rate of nitrogen-vacancy (NV) centers. Our structures consist of single nitrogen-vacancy (NV) center-containing diamond nanoposts embedded in a thin silver film. We have utilized the strong plasmon resonances in the diamond-silver apertures to enhance the spontaneous emission of the enclosed dipole. The devices were realized by a combination of ion implantation and top-down nanofabrication techniques, which have enabled deterministic coupling between single NV centers and the plasmonic modes for multiple devices in parallel. The plasmon-enhanced NV centers exhibited over six-fold improvements in spontaneous emission rate in comparison to bare nanoposts and up to a factor of 3.6 in radiative lifetime reduction over bulk samples, with comparable increases in photon counts. The hybrid diamond-plasmon system presented here could provide a stable platform for the implementation of diamond-based quantum information processing and magnetometry schemes.Comment: 16 pages, 4 figure

How circular design can contribute to social sustainability and legacy of the FIFA World Cup Qatar 2022™? The case of innovative shipping container stadium

The circular economy proposes a paradigm shift from the ‘take-make-waste’ type of economic system and aims to foster innovation, resource efficiency, and waste prevention. Mega sporting events can be considered great opportunities to promote sustainable cities and communities and leave a lasting positive legacy after the post-game stage. Qatar will organize the upcoming FIFA World Cup in 2022 and Ras Abu Aboud (RAA) is designed as a fully reusable and modular shipping container stadium, which will be dismantled, relocated, and reused after the tournament. This study aims to present the first comprehensive analysis on the social sustainability and legacy aspects of a circular and sharing economy application for the FIFA World Cup organization. The research analyzes the entire life cycle phases of the RAA stadium including the raw material production, construction, operations, and end-of-life. The Ecoinvent v.3.7.1 is used to quantify the midpoint environmental and endpoint human health impacts. For its operation phase assessment, two operation scenarios are comparatively analyzed: one-year temporary operation (Scenario 1) and 50 years of permanent operation (Scenario 2). Later, a simulation-based sensitivity analysis is conducted. Finally, we discussed how circular and modular design thinking can bring long-lasting legacy post-event, through reuse and recycling from a socio-economic perspective. An important finding shows that circular design under Scenario 1 can save up to 60% of human health impacts and significantly reduce the material footprint and dependence on imported construction materials. This research will enhance future awareness for sustainability benefits of circular and sharing economy application adopted by mega sporting events concerning the United Nations 2030 Agenda for Sustainable Development and FIFA's post-game legacy and sustainability strategies

Microstructured magnetic materials for RF flux guides in magnetic resonance imaging

Abstract: We present novel metamaterial structures based upon various planar wallpaper groups, in both hexagonal and square unit cells. An investigation of metamaterials consisting of one, two, and three unique sub-lattices with resonant frequencies in the terahertz (THz) was performed. We describe the theory, perform simulations, and conduct experiments to characterize these multiple element metamaterials. A method for using these new structures as a means for bio / chemical hazard detection, as well as electromagnetic signature control is proposed

Structural Integrity Assessment of an Uncompleted Reinforced Concrete Structure in Maiduguri, Nigeria

Structural integrity assessment of an existing structure/building was carried out to determine its reliability to addition further load while fulfilling its intended function. From the assessment result, the building had shown a yielded slab, probably due to observable deterioration of the building elements (Block D). Further assessment of this study’s result reveals the major cause for that concern, and it is due to low slab strength value (NDT <20N/mm2). Additionally, the structural deterioration which has occurred is as a direct result of the neglect and inability to appropriately drain rain water on the slab from the building. Therefore, this study’s result indicates that, the components (Block D) does not have adequate resistance to cater for future loads, because of the demonstrated structural failures associated with the building(slab) in question. The masonry walls of the building’s non-structural components were also observed to be having some extent of cracks and other distress. It is therefore recommended that reconstruction of the distressed area be carried out. Study further suggest combination of tests, instead of performing just one type of test, provide more suitable results to confidently accept or reject the structure as a whole or its component for future use
