Kitchen Design for Water Recycling and Building New Family Relationships

Air and water are the most important resource for mankind. Water conservation is a concept that everyone knows, but how many water conservation products can we see in our life? Kitchen water is one of the most important parts of domestic water use, and its life cycle in the kitchen should be given more attention. Making good use of kitchen water will bring environmental benefits to our future generations. This article will first discuss the current situation of kitchen water and the need for reuse of water resources, and then discuss the ways of reusing kitchen water. This article will discuss the new relationships between family members in the future in helping to preserve and reuse water in the kitchen. This article will also discuss a kitchen layout that builds a closer relationship between family members in our future life, creates a variety of life scenes through the design of space and user movements, and explores the relationship between different shapes to achieve the most effective way of using space. At the same time, it satisfies the user\u27s daily behavior when using the kitchen. Then, this article will discuss a kitchen design that can reuse water resources and build more life scenarios. At last, this article will show the potential of this design in the future

The Inquiry of Storytelling Narrative in the Museum Display Design

This article starts from space story construction, display scene design and the “people-oriented†experience design direction, combines with quality cases that leading the world museum display design, discusses how to use the storytelling narrative into museum display design. The paper will help better promote the plot development between space and exhibits, exhibits, people and exhibits, optimize thesocial education function of traditional museum, and spread exhibition information more effectively

Imaging mechanism and contrast separation in low-voltage scanning electron microscopy imaging of carbon nanotube arrays on SiO2/Si substrate

Polymer-sorted high-density carbon nanotube (CNT) arrays have shown great potential to extend the silicon-based Moore's law. Imaging the CNT arrays on insulators like SiO2/Si using low-voltage scanning electron microscopy (LVSEM) to acquire array information like the alignment, density, and distribution of residual polymers is necessary. Such a task remains challenging due to the nanoscale CNT body (1-2 nm in diameter), nanoscale tube-to-tube separation (1-10 nm), the broadening of the apparent diameter, and the complex image contrast caused by the insulating substrate and polymer residues. In this study, the imaging mechanism for this system is investigated. Two methods are developed to separate the three dominant contrasts, i.e. topographic contrast, charge contrast, and material contrast, by selecting the take-off angle and energy of the emitted electrons as enabled by changing the working distance or the deceleration voltage. The contrast formation and separation mechanism is further confirmed by the dynamic contrast evolution due to the electron-beam-induced deposition of amorphous carbon. The contrast separation method is further applied to an individual CNT, reducing its apparent diameter from 36 nm to 6 nm. This result hints at the potential for LVSEM to count the density exceeding 150 CNTs/um of CNT arrays. Finally, a comparative study of LVSEM and transmission electron microscopy confirms the failure of LVSEM to resolve CNTs in a bundle. The results suggest that the density of CNT arrays may be underestimated in reported SEM data. The proposed method can serve as a useful tool for further study and application of arrayed CNTs.Comment: 25 pages, 9 figures main text. 5 pages, 6 figures supplementary material

Expenditures and Use of Hypofractionated Radiation Therapy Treating Breast Cancer Among Medicare Advantage Enrollees, 2009 to 2017

Purpose: Technology advances in cancer care have paralleled rapidly increasing expenditures in radiation therapy. The use and costs of shorter cancer radiation therapy offer potential utility in clinical practice. We evaluate use and expenditures of Medicare Advantage (MA) beneficiaries receiving hypofractionated whole breast irradiation (HF-WBI) compared with conventionally fractionated whole breast irradiation (CF-WBI) in the United States and examine the relationship of patient characteristics with HF-WBI use. Methods and materials: We performed a retrospective analysis of radiation therapy in MA beneficiaries using private employer-sponsored insurance claims for a pooled cross-sectional evaluation from 2009 to 2017. The study population included female MA beneficiaries with early-stage breast cancer treated with lumpectomy and whole breast irradiation. Results: A total of 9957 women received HF-WBI, and 18,920 received CF-WBI. Older age, greater distance from home to treatment facility, and a higher proportion of college graduates in the community of residence were associated with increased HF-WBI use. Mean insurer-paid radiation therapy expenditures were significantly lower for HF-WBI versus CF-WBI (adjusted difference, 4113 dollars; 95% CI, 4030-4,197 dollars). Mean patient out-of-pocket expenditure for HF-WBI was 426 dollars less than that of CF-WBI. Across US states, geographic variation existed in the ratio of costs for HF-WBI relative to CF-WBI (range, 0.41-0.87). Conclusions: HF-WBI use among MA beneficiaries with breast cancer has dramatically increased over time, surpassing CF-HBI as the dominant form of radiation therapy. HF-WBI clinical adoption has outpaced any continual cost decrease, despite wide variation across US states for this shorter radiation therapy treatment. As MA enrollment continues to expand, identifying the drivers of HF-WBI use and the sources of variation in costs of HF-WBI will help direct the quality of cancer care delivered to Medicare beneficiaries.</p

The correspondence between shadows and test fields in four-dimensional charged Einstein-Gauss-Bonnet black holes

In this paper, we investigate the photon sphere, shadow radius and quasinormal modes of a four-dimensional charged Einstein-Gauss-Bonnet black hole. The perturbation of a massless scalar field in the background of the black hole is adopted. The quasinormal modes are gotten by the $6th$ order WKB approximation approach and shadow radius, respectively. The degree of coincidence of the quasinormal modes derived by the two approaches increases with the increase of the values of the Gauss-Bonnet coupling constant and multiple number. It shows the correspondence between the shadow and test field in the four-dimensional Einstein-Gauss-Bonnet-Maxwell gravity. The radii of the photon sphere and shadow increase with the decrease of the Gauss-Bonnet coupling constant.Comment: 16 page
