A K Thota Radhakrishnan, J B van Lier, F H L R Clemens
The much over-looked element in new sanitation, the transport systems which bridge the source and treatment facilities, is the focus of this study. The knowledge of rheological properties of concentrated domestic slurry is essential for the design of the waste collection and transport systems. To investigate these properties, samples were collected from a pilot sanitation system in the Netherlands. Two types of slurries were examined: black water (consisting of human faecal waste, urine, and flushed water from vacuum toilets) and black water with ground kitchen waste...

In order to develop an effective bioaugmentation strategy for the removal of highly toxic and recalcitrant tricyclazole from wastewater, a tricyclazole degrading strain was firstly successfully isolated and identified as Sphingomonas sp. NJUST37. In batch reactors, 100 mg L-1 tricyclazole could be completely removed within 102 h, which was accompanied by significant biomass increase, TOC and COD removal, as well as toxicity reduction. Chromatography analysis and density functional theory simulation indicated that monooxygenation occurred firstly, followed by triazole ring cleavage, decyanation reaction, hydration reaction, deamination, dihydroxylation and final mineralization reaction...

Pigment-grade titanium dioxide (TiO2) of 200-300 nm particle diameter is one of the most widely used submicron-sized particle materials. Inhaled and ingested TiO2 particles are known to enter the bloodstream, to be phagocytized by macrophages and neutrophils, to be inflammatory, and to activate the NLRP3 inflammasome. In this pilot study of 11 pancreatic specimens, 8 of the type 2 diabetic pancreas and 3 of the non-diabetic pancreas, we show that 110±70 nm average diameter TiO2 crystals abound in the type 2 diabetic pancreas, but not in the non-diabetic pancreas...

One of the first steps to early integrate palliative care into oncology practice is a timely and efficient evaluation of symptoms (Bakitas et al., 2015; Davis et al., 2015; Temel et al., 2010). In a recent position paper, the Italian Association of Medical Oncology tells oncologists that they "must be able to prevent, recognize, measure, and treat all cancer-related symptoms" (Zagonel et al., 2017). Major international scientific societies such as the American Society of Clinical Oncology and the European Society of Medical Oncology have often defined the key role of symptoms evaluation and management to force the integration of palliative care into oncology (Davis et al...

FSG is a mission-driven nonprofit organization supporting leaders in creating large-scale, lasting social change. A survey conducted by FSG in 2015 across 4407 low-income families in urban India showed that 95% of them send their children to preschools, a majority of choosing affordable private preschools (APSs), as parents perceive the quality of government schools to be poor. Parents use and value rote-based methods (e.g., reciting poems) to assess their children's learning in school; however, these methods fail to measure conceptual understanding...

Small pilot studies of young children have frequently shown promise, but very few have been successfully scaled to the regional or national levels. How can we ensure that these promising approaches move from a suite of pilots to full-scale implementation that can deliver sustainable impact for hundreds of millions of children? To elucidate concrete lessons learned and suggestions on accelerating the transition to impact at scale, we reviewed the Saving Brains portfolio to better understand three points: (1) the extent to which useful signals of impact could be extracted from data at the seed phase, (2) the ways in which innovators (project leaders) were approaching human resource challenges critical for scaling, and (3) the multisector diversity of the portfolio and the way innovators entered partnerships...
