Based on the consumption of fossil energy, the CO₂ emissions of Chongqing are calculated and analyzed from 1997 to 2015 in this paper. Based on the calculation results, the consumption of fossil fuels and the corresponding CO₂ emissions of Chongqing in 2020 are predicted, and the supporting data and corresponding policies are provided for the government of Chongqing to reach its goal as the economic unit of low-carbon emission in the '13th Five-Year Plan'. The results of the analysis show that there is a rapid decreasing trend of CO₂ emissions in Chongqing during the '12th Five-Year Plan', which are caused by the adjustment policy of the energy structure in Chongqing...

AIM: The prevalence of diabetes in older adults in residential aged care (RAC) is twice that of community dwelling older adults. Older adults with diabetes have been highlighted as being at high risk of frailty and malnutrition, particularly when managed on a therapeutic diet. However, assumptions may be based on clinical presentation of our oldest old which may be at conflict with the clinical presentation of younger older adults. The aim of this retrospective audit was to identify the characteristics of aged care residents with diabetes, their comorbidities and malnutrition risk...

Bottom-up neuroscience aims to engineer well-defined networks of neurons to investigate the functions of the brain. By reducing the complexity of the brain to achievable target questions, such in vitro bioassays better control experimental variables and can serve as a versatile tool for fundamental and pharmacological research. Astrocytes are a cell type critical to neuronal function, and the addition of astrocytes to neuron cultures can improve the quality of in vitro assays. Here, we present cellulose as an astrocyte culture substrate...

The field of microfluidic paper-based analytical devices (μPADs) is most notably characterized by portable and low-cost analysis; however, struggles to achieve the high sensitivity and low detection limits needs required for many environmental applications hinder widespread adoption of this technology. Loss of analyte to the device material represents an important problem impacting sensitivity. Critically, we found that at least 50% of a Ni(II) sample is lost when being transported down a 30 mm paper channel that is representative of structures commonly found in μPADs...

Ever since Bitner defined the term "servicescape" as the physical environment in which the service is assembled, several scholars have attempted to better understand the impact of the built environment in the context of different service settings. While servicescape is a topic of increasing academic interest among scholars and practitioners, most studies in the area are dedicated to understanding the built environment of hedonic service. More studies are needed to examine utilitarian servicescape and in this paper, we have focused on the healthcare environment...

Objective To integrate and synthesize insights from recent studies of workarounds to the intended use of health information technology (HIT) by health care professionals. Background Systems are safest when the documentation of how work is done in policies and procedures closely matches what people actually do when they are working. Proactively identifying and managing workarounds to the intended use of technology, including deviations from expected workflows, can improve system safety. Method A narrative review of studies of workarounds with HIT was conducted to identify themes in the literature...

The optimal frequency (OF) of a biomarker in electrochemical impedance spectroscopy (EIS) is the frequency at which the EIS response best reflects the binding of the biomarker to its molecular recognition element. Commonly, biosensors rely on complicated immobilization chemistry to attach biological molecules to the sensor surface, making the direct study of a biomarker's native OF a challenge. Physical adsorption presents a simple immobilization strategy to study the native biomarker's OF, but its utility is often discouraged due to a loss in biological activity...

Wallpaper with multiple functions, such as fire resistance and an automatic alarm in fire disasters, will be attractive for the interior decoration of houses. Herein, we report a smart fire alarm wallpaper prepared using fire-resistant inorganic paper based on ultralong hydroxyapatite nanowires (HNs) and graphene oxide (GO) thermosensitive sensors. At room temperature, the GO thermosensitive sensor is in a state of electrical insulation; however, it becomes electrically conductive at high temperatures. In a fire disaster, high temperature will rapidly remove the oxygen-containing groups of GO, leading to the transformation process of GO from an electrically insulated state into an electrically conductive one...

The incidence of flavivirus infections has increased dramatically in recent decades in tropical and sub-tropical areas worldwide, affecting hundreds of millions of people each year. Dengue viruses are typically transmitted by mosquitoes and can cause a wide range of symptoms from flu-like fever to organ impairment and death. Although conventional diagnostic tests can provide early diagnosis of acute dengue infections, access to these tests is often limited in developing countries. Consequently, there is an urgent need to develop affordable, simple, rapid, and robust diagnostic tools that can be used at 'Point of Care' settings...

This paper describes a new approach for the massive production of electrochemical paper-based analytical devices (ePADs). These devices are fully fabricated by screen-printing technology and consist of a lineal microfluidic channel delimited by hydrophobic walls (patterned with diluted ultraviolet screen-printing ink in chromatographic paper grade 4) and a three-electrode system (printed with carbon and/or Ag/AgCl conductive inks). The printing process was characterised and optimized for pattern each layer with only one squeeze sweep...

A high-efficient photo-induced wastewater fuel cell (WFC) for neutral wastewater treatment was proposed in this paper based on radicals catalytic reaction of Fe3+ /Fe2+ - EDTA complexes in the system which has a lower redox potential than Fe3+ /Fe2+ and can accelerate easily the conversion of slow catalytic step from Fe (III) to Fe (II). The results indicated that the WFC shows an excellent performance in a wide pH range of 5-9 and achieves optimal efficiency for organic degradation and electricity generation at pH 7...
