The increasing applications of low-cost air sensors promises more convenient and cost-effective systems for monitoring in many places under conditions. However, the data quality from such has not been fully characterized may meet user expectations research regulatory uses, or use citizen science. In our study, electrochemical (Alphasense B4 series) carbon monoxide (CO), nitric oxide (NO), nitrogen dioxide (NO2), oxidants (Ox) were evaluated controlled laboratory conditions to identify...
Abstract Flexible pressure sensors as wearable electronic devices to monitor human health have attracted significant attention. Herein, a simple and effective carbonization-free method is proposed prepare compressible conductive reduced graphene oxide (rGO)–modified plant fiber sponge (defined rGO-PFS). The introduced GO can not only coat on the surface of fibers, but also form large amount aerogel with microcellular structure in macroporous PFS. After reduction treatment, rGO-PFS...
This study presents the development and evaluation of a next generation air monitoring system with both laboratory field tests. A multi-parameter algorithm was used to correct for impact environmental conditions on electrochemical sensors carbon monoxide (CO) nitrogen dioxide (NO2) pollutants. The in an urban roadside environment comparison designated monitors showed good agreement measurement error within 5% pollutant concentrations. Multiple sets developed were then deployed Hong Kong...
Abstract. We present two-dimensional scanning Multi-AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) observations of nitrogen dioxide (NO2) and formaldehyde (HCHO) in Munich. Vertical columns vertical distribution profiles aerosol extinction coefficient, NO2 HCHO are retrieved from the 2D MAX-DOAS observations. The measured surface coefficients mixing ratios derived compared to situ monitoring data, show a good agreement with data Pearson correlation coefficient (R) 0.91. optical...
The influence of traffic regulations on urban air quality has been discussed for years, especially during the COVID-19 lockdowns, when significant shifts in were observed, particularly concentration nitrogen dioxide (NO₂), a key pollutant linked to vehicular emissions and industrial activities. This study provides long-term analyzes variation NO₂ levels an environment, investigation interplay various influencing factors lockdown periods Munich, Germany, including volume,...
Abstract. In many cities around the world overall air quality is improving, but at same time nitrogen dioxide (NO2) trends show stagnating values and in cases could not be reduced below standards recommended by World Health Organization (WHO). Many large have built monitoring stations to continuously measure different pollutants. While most follow defined rules terms of measurement height distance traffic emissions, question remains how representative are those point measurements for...
Abstract. In this paper we present an investigation of the spatial and temporal variability street-level concentrations NO2 in Hong Kong as example a densely populated megacity with heavy traffic. For study use combination open-path remote sensing situ measurement techniques that allows us to separate changes patterns analyse them separately. Two campaigns have been conducted, one December 2010 March 2017. Each campaign lasted for week which allowed examine diurnal cycles, weekly well...
Air quality have become a global issue with increasing attention. There is growing concern in the public about both in- and outdoor air quality. In order to monitor individual pollutants exposure real-time, we developed several wearable monitoring devices study personal different environments. The are equipped type of sensors measure NO2, aerosols, CO2, etc, addition environmental parameters sensor temperature, relative humidity pressure. optimize accuracy, compared retrieval approaches such...
The weakness of traditional dumbbell-shaped section is that when concrete filled into the web space, great stress likely to produce cracks in weld sealing between steel tube and plates. In order avoid this condition, a new-type proposed. Experiments on tubular (CFST) model arches with have been carried out, concentrated loading at crown L/4 respectively. result indicated CFST arch has good elastic-plastic behavior high strength, no local buckling appeared during whole process, its in-plane...
Experiments on concrete filled steel tubular (CFST) model arches with new-type dumbbell-shaped section have been carried out, concentrated loading at crown and L/4 respectively. Applied large general program ANSYS, a finite element calculation was set up for the arch, by means of this main parameters including arch axis coefficient, ratio rise to span, slenderness ratio, are analyzed. Based discussion influence parameter variation nonlinear characteristics ultimate load-carrying capacity...
OBJECTIVE To find out the diet measurements for alleviating symptoms of lactose intolerance when people had a drink milk. METHODS Eight (LI) subjects suffering from watery diarrhea were selected 38 by using hydrogen breath test (HBT) joined drinking cow's milk along with various other foods designed orthogonal trial. The 100 healthy college students to observe after they ingested 25 g powder in different manners. RESULTS breath-hydrogen concentration groups ingesting and was lower than those...
As a source of clean green renewable new energy, wave power generation is paid much attention by more countries while the decrease amount energy day day. The conversion technology in field has tended to mature. Now it running into commercial exploitation leve1. In this paper, fundamental principles ocean are presented. classification and present situation device introduced. At last, some possible directions prospects expatiated.
Abstract. In this paper we present an investigation of the spatial and temporal variability street level concentrations NO2 in Hong Kong as example for a densely populated megacity with heavy traffic. For study use combination open path remote sensing in-situ measurement techniques that allows us to separate changes patterns analyse them separately. Two campaigns have been conducted, one December 2010 March 2017. Each campaign lasted week which allowed examine diurnal cycles, weekly well...
