Herein, the recent advances in realizing highly efficient cellulose-based solar evaporators for alleviating the global water crisis are summarized. Fresh water scarcity is one of the most threatening issues for sustainable development. Solar steam generation, which harnesses the abundant sunlight, has been recognized as a sustainable approach to harvest fresh water. In contrast to synthetic polymeric materials that can pose serious negative environmental impacts, cellulose-based materials, owing to their biocompatibility, renewability, and sustainability, are highly attractive for realizing solar steam generators. The molecular and macromolecular features of cellulose and the physicochemical properties of extracted cellulose nanoparticles (cellulose nanocrystals and cellulose nanofibrils (CNF)) and natural cellulose materials (wood and bacterial nanocellulose (BNC)) that make them attractive as supporting substrate materials in solar steam generators are briefly discussed. Recent progress in designing highly efficient cellulose-based solar evaporators, including utilizing extracted cellulose nanoparticles via bottom-up assembly CNF, natural cellulose materials with intrinsic hierarchical structure (wood and BNC), and commercial planar cellulose substrates (air-laid paper, cellulose paper, and cotton fabric) is reviewed. The outstanding challenges that need to be addressed for these materials and devices to be utilized in the real-world and in overcoming global water crisis are also briefly highlighted.We use a simple model to study the static and dynamic efficiency of alternative regulation regimes for the reimbursement of medical innovations when responses to a new treatment (effectiveness) are heterogeneous across the eligible population. When the rational behavior of profit-maximizing firms is taken into account, only average value-based prices can ensure both static and dynamic efficiency, but they imply higher expenditure and lower consumer surplus. Ignoring dynamic efficiency, if patients' responses are sufficiently homogeneous, marginal value-based prices may dominate from the payer's perspective. We also present a refinement of average value-based prices that could reverse this result. Overall, the cost of ensuring static and dynamic efficiency is increasing in the degree of heterogeneity. A real-world example is used to illustrate these results.Childhood maltreatment is consistently associated with poor outcomes. However, few epidemiological studies have examined the association between childhood maltreatment and adult resilience capacity, defined as one's perceived ability to cope successfully with challenges. This study aimed to determine associations between adult resilience capacity and specific types and features of childhood maltreatment. Participants were African American adults recruited from a public urban hospital in Atlanta, GA (N = 1,962) between 2005 and 2013. Childhood maltreatment, including witnessing domestic violence or physical, emotional, and sexual abuse, was assessed retrospectively using the Traumatic Events Inventory. Perceived resilience capacity was assessed using the Connor-Davidson Resilience Scale. Linear regressions were performed assessing the association between resilience capacity and childhood maltreatment exposure in general, as well as specific dimensions of exposure, including type, co-occurrence, and developmental timing, adjusting for covariates. Participants exposed to any maltreatment reported lower resilience capacity than unexposed peers, B = -0.38, SE = 0.04, p less then .001. All maltreatment types were negatively associated with resilience capacity, even after adjusting for other lifetime trauma exposure. Only emotional abuse remained significantly associated with resilience capacity after accounting for current psychological distress, B = -0.11, SE = 0.05, p = .022. Maltreatment co-occurrence followed an inverse dose-response relationship with resilience capacity For each additional maltreatment type, scores decreased by 0.18 units (SD = 0.02), p less then .001. Finally, the developmental timing of maltreatment did not reveal any differential influences on resilience capacity. The results suggest that childhood emotional abuse and co-occurrence of maltreatment types may be particularly deleterious to adult resilience capacity.Hardening issue in starch-based products that arises during storage, is ascribed to the long-term starch retrogradation which involves the recrystallisation of amylopectin. Present study aimed to delay storage hardening with the addition of high diastase honey bee honey (HBH) and low diastase kelulut bee honey (KBH) into glutinous rice flour (GRF) gels. As compared to KBH, retardation of texture deterioration by HBH was more prominent as evidenced by the significantly (p less then 0.05) lowest hardness and rate of hardening of GRF gel added with HBH (honeygel) throughout the 7-day storage. Heated honey and sugar solution did not reduce gel hardness that gel weakening was associated to the naturally occurring diastase in raw honey. Selleckchem Opicapone Hence, only conventional GRF gel (congel), GRF gel added with KBH (kelugel) and honeygel were assessed for intrinsic viscosity, thermal, microstructural and chemical properties. The results were substantiated by the significantly (p less then 0.05) lowest intrinsic viscosity (62.93 mL/g) and thermal enthalpy (333.7 J/g) of honeygel. A weak gel network structure was illustrated in honeygel with the significantly (p less then 0.05) highest pore diameter (125.27 μm). In conclusion, the GRF gel has successfully demonstrated the potential of honey diastase in inhibiting the long-term retrogradation which could solve the industrial real problem.

With this technique, a single vertebral body stent was deployed percutaneously in the midline of the vertebral body using cone-beam computed tomography (CBCT) guidance. Methods From September 2013 to July 2015, forty-four patients with fifty-six vertebral bodies underwent central stentoplasty. All fractures were of osteoporotic, traumatic or malignant aetiology. Information on vertebral body deformity, pre- and post-procedure sagittal index (SI), wedge angle (WA) and anterior vertebral height ratio was analysed. Two patients had combined ablation and stentoplasty for painful spinal metastases. Results There were 11 male and 33 female patients with mean age of 71.5 years (51-90 years). 19 fractured vertebral bodies had more than 30% loss of height. The mean pre-procedure SI was 0.82, and the mean post-procedure SI was 0.90. The pre-procedure WA was -5.56° compared with post-procedure mean WA of -3.
