Abstract:
A feasibility study was conducted to develop a novel method to determine the temporal changes of tensile forces in bridge suspender cables using time-frequency analysis of ambient vibration measurements. An analytical model of the suspender cables was developed to evaluate the power spectral density (PSD) function of a cable with consideration of cable flexural stiffness. Discrete-time, short-time Fourier transform (STFT) was utilized to analyze the recorded acceleration histories in both time and frequency domains. A mathematical convolution of the analytical PSD function and time-frequency data was completed to evaluate changes in cable tension force over time. The method was implemented using acceleration measurements collected from an in-service steel arch bridge with a suspended deck to calculate the temporal variation in cable forces from the vibration measurements. The observations served as proof of concept that the proposed method may be used for cable fatigue life calculations and bridge weigh-in-motion studies.

Abstract:
A humidity sensor using suspended carbon nanotubes (CNTs) was fabricated using a low-temperature surface micromachining process. The CNTs were functionalized with carboxylic acid groups that facilitated the interaction of water vapor with the CNTs. The humidity sensor showed a response time of 12 s and a recovery time of 47 s, along with superior hysteresis and stable performance. The hysteresis curve area of the suspended structure is 3.6, a 3.2-fold reduction in comparison to the non-suspended structure. A comparative study between suspended and non-suspended devices highlights the advantages of using a suspended architecture.

Abstract:
Environmental water monitoring requires the estimation of the suspended solids load. In this paper, we compare the concentration range accessible through three different techniques: optical turbidity, acoustic backscattering and the newly in-lab developed time resolved optical turbidity. We focus on their comparison on measurements made in the laboratory on water suspensions of known particles and concentrations. We used laboratory grade kieselguhr, wheat starch and kaolin as suspended solid surrogates. The explored concentration domains are the ones, for the total suspended solid load, commonly encountered in wastewater and rivers in standard (less than 1 g/L to a few g/L) or extreme conditions such as floods or storm events (up to several dozen g/L). Regarding the operable concentration domain, the time resolved optical turbidity shows a clear advantage upon the other methods, whatever the kind of particle is.

Abstract:
The effect of estuary type suspended solids on E.coli inactivation has been examined in laboratory experiments. The work used artificial seawater, laboratory processed suspended solids and chemostat steady-state E.coli cultures to establish the effect of these physical/chemical parameters on the viability of an E.coli population. Initial E.coli concentrations were 5 × 103. 100ml−1, the temperatures employed were 10°C and 20°C, the suspended solids concentration range was 0 – l00mgl−1, salinity range 10 – 32%o, and the experimental vessels were completely shielded from light. The introduction of suspended solids at a low concentration (ie 5mgl−1) markedly increased the survival time of E.coli at the higher salinities (ie 32% o and 27%o). Suspended solids at higher concentrations (>12.5mgl−1) provided no additional increase in survival time. At low suspended solids concentrations (≤5mgl−1) decreasing salinity increased survival time; at higher suspended solids concentration (>12.5mgl−1) salinities in excess of a critical value, around 27%o, also increased survival times.

Abstract:
Suspended animation emerged as a concept in the late eighteenth century as part of the efforts of the newly founded Royal Humane Society to convince lay and medical readers that individuals who had apparently drowned might still be alive, albeit in states of “suspended animation” (a condition we would now likely describe as a coma). The term was quickly taken up by medical and literary authors, including Samuel Taylor Coleridge, Mary and Percy Bysshe Shelley, and John Keats. Exploring these Romantic-era approaches to suspended animation can help us understand the reception and formal structures of creative literature, grasp the often counterintuitive links that Romantic-era authors established between “altered states” and “Romantic sobriety,” and articulate why poetry and other slow media remain important in our contemporary new-media landscape.

Abstract:
The Vincent Thomas Bridge in Los Angeles, California, is a major suspension bridge with a total length of 1848 m (6,060 ft), including approaches, and a main span bridge 766 m (2,513 ft) long, whose center span is 458 m (1,500 ft). The bridge, built in the 1960s, used the seismic codes of the time. The site conditions and tall, slender towers and bents have resulted in vulnerabilities that are particular to suspended bridges. This paper focuses on the suspended spans. The bridge is located within the Port of Los Angeles in a vicinity that has a legacy of earthworks associated with such projects as dock expansion, fuel lines, and rail lines. Geotechnical conditions include an active fault running between the main towers with a potential for liquefaction, fault rupture, and lateral spreading. A nonlinear time history analysis of the main suspended bridge was performed, using ADINA. The model included the effects of geometric stiffness of the cables and of multiple-support excitation of the bridge. The critical vulnerabilities detected in this study, arising from large predicted longitudinal motions, indicated distress in the towers, in the cable bents near the anchorages, in the short midspan suspenders, and in the stiffening trusses. During the retrofit study the nonlinear behavior was further developed, including tower rocking and uplift, the postyield deformations of the tower, and the optimization of the damper properties. Retrofit measures include releasing of the side-span trusses at the cable bents, creating fused hinges in the stiffening trusses, the installation of dampers at these locations and between the stiffening trusses and the towers of the bridge, stiffening of the bridge towers to prevent plate buckling, and cable and suspender modifications.

Based on the field observations and laboratory analysis data of the suspended sediment of Wendeng coastal area, this paper studied the change process of suspended sediment concentration and characteristics of surface sediment resuspension in the study area. In results: (1) In vertical, the suspended sediment concentration of each station increased gradually from surface to bottom, and the maximum value could reach 0.11 kg/m3; (2) Suspended sediment concentration is well correlated with velocity variation in a tidal cycle, and the peak of suspended sediment concentration occurs four times in a tidal cycle, indicating that there are four resuspension processes during a tidal cycle in the study area; (3) According to the suspended sediment concentration at different times and the content of the previous time, the maximum settlement is between 0.063~0.092kg/m3, and the maximum resuspension is between 0.057~0.125kg/m3 in the study area.

Abstract:
A novel building structure system, namely core-tube vibration-reduction suspended structure (CVRSS), is put forward in this paper. The basic composition and calculation model for the structure system are described. The El Centro and Taft seismic waves are used to calculate the dynamic characteristics of the structure in the time domain, of which dynamic responses are proved satisfactory. Taking the top floor displacement of the primary structure and the relative displacement between bottom layer of suspended segments and top floor of core-tube as objective function, the finite element model is established, and comparative analysis with common core-tube suspended structures (CCSS) is performed. The results show that the top floor displacement of CVRSS is about 70% of that of CCSS, and the vibration-reduction performance of CVRSS is excellent.

Abstract:
The paper analyzes suspended particles number concentrations of 61 size fractions (184 nm to 17,165 nm) in the air at a traffic location. The average course of the individual fractions was analyzed at various intervals – daily, weekly, monthly and annually, in the period between 2017 and 2019. The data was then used to calculate the arithmetic mean for all the fractions (MS Excel, R) and then using a proprietary web application, heatmaps were constructed. The obtained results showed significant differences in both the annual and daily variation of number concentrations between the individual fractions differing in particle size. In the case of the annual variation, one can see a greater variability of smaller particles, which is most likely due to the source of the actual suspended particles. Meteorological and dispersion conditions are found as important factors for suspended particle concentrations. These can lead to significant differences from year to year. However, a comparison between 2018 and 2019 showed that even though the average absolute number concentrations can differ between years, the actual relative number concentrations, i.e., the ratios between the individual fractions remain very similar. In conclusion it can be said that the difference between the number concentration variation of the size fractions depends on both the actual pollution sources (especially in the long-term, i.e., the annual variation) and the actual size of the particles, which plays a role especially in the short-term (daily, weekly variation).

Abstract:
The effect of dissolved nutrients and inorganic suspended solids on E. coli inactivation has been examined in laboratory experiments. The work employed artificial seawater with dissolved glucose and peptone, laboratory processed suspended solids and chemostat steady state E. coli cultures to establish the effect of these parameters on the viability of an E. coli population. Initial E. coli concentration was 5 × 103 100ml−1, the temperatures 5 °C and 20°C, the suspended solids concentration range was 0 - 100mgl−1, glucose concentration l.0mgl −1, peptone concentration 9.0mgl−1, salinity range 27 - 32‰ and the experimental vessels were shielded from light. Previous work has shown that nutrient-free inorganic suspended solids, at low concentrations, markedly increased the survival of E. coli in seawater. The work presented here shows that the presence of dissolved nutrients greatly increased E. coli survival, in the absence of suspended solids. However at suspended solids concentrations of &gt;5 - 12mgl−1survival time was greatly reduced; thereafter increasing suspended solids concentration in the range &gt;12.5 - 100mgl−1, generally resulted in increasing survival times.

The paper presents the results of analyzes of the granulometric composition of suspended solids in backwash water from biological activated carbon (BAC) filters and its changes during sedimentation. Backwash water samples were taken during backwashing of two pilot filters after different filtration time. It was found that regardless of the concentration of suspended solids in the collected backwash water, particle sizes vs. their percentage volume contributions for all samples were similar. Particle sizes were in the range of 2–100 μm. However, the two-hour sedimentation for most of the samples proved to be effective (total suspended solids removal up to 93%), which is caused by self-coagulation of the sample.

Abstract:
Research has shown the importance of prospective thinking in the understanding of individual behaviour across different contexts. However, there has not been extensive attention paid to individuals’ future time perspective (FTP) in non-normative contexts, such as prison, especially using qualitative research methods. In this study, we qualitatively analyse the FTP of 16 Portuguese male prisoners, ranging in age from 24 to 51 years ( M = 35, SD = 8 (idem)) and serving sentences from one to 25 years ( M = 8.6, SD = 7.3). Through content analysis of data obtained in semi-structured interviews, four main categories emerged: life prior to prison, adaptation to prison, activities in prison, and perspectives concerning the future. Considering the primary features of FTP (content, extension, valence), we determined that prisoners develop FTP in different life domains. However, the extension and emotional valence of their FTP were influenced by the sentence time and perceived social support. The results are discussed regarding the importance of counselling and of the construction of future plans in the context of prison as relevant factors for individual adaptability.

Abstract:
A one-time etching suspended microracetrack resonator with lateral sub-wavelength-grating (SWG) metamaterial cladding is theoretically and experimentally demonstrated on commercial 340 nm-thick-top-silicon silicon-on-insulator (SOI) platform for mid-infrared (MIR) bio-chemical sensing applications. The suspended structure can offer a larger exposed area of waveguides with the testing chemicals as well as a decent sensitivity. And the one-time etching process also eases the fabrication. The suspended waveguide is optimized with a balance between propagation loss and the sensitivity. The suspended microracetrack resonator is experimentally measured at 2 μm wavelength and well fitted with an extinction ratio (ER) of 12.3 dB and a full-width-at-half-maximum (FWHM) of 0.12 nm, which corresponds to a quality factor (Q factor) of 16600. With the equivalent refractive index method and a specially developed numerical model, the expected sensitivities of fundamental TE and TM mode were calculated as 58 nm/RIU and 303 nm/RIU respectively. This one-time etching suspended microracetrack resonator shows great potential in MIR optical bio-chemical sensing applications.

Abstract:
The Hong Kong-Zhuhai-Macau Bridge crosses the Pearl River Estuary and is the largest bridge and tunnel project in the world. During the construction period of this project, the excessive suspended sediment was found in the construction region. The suspended sediment generated by sand excavation in the upstream was assumed to have a significant impact on the suspended sediment in the tunnel region. In this study, we assessed the impact of upstream sand excavation on the suspended sediment in the Hong Kong-Zhuhai-Macau Bridge construction area using Landsat OLI, ETM+, and TM data. Regional suspended sediment algorithms were developed for Landsat using a symbolic regression method based on data from in situ measurements in the study area from 2003 to 2014. A band shift was conducted on the remote sensing reflectance data from Landsat ETM+ and OLI to produce a time series of the suspended sediment concentrations that was internally consistent with that of the Landsat TM data. The suspended sediment distribution was extracted and used to compare under two different conditions, with and without sand excavation. The correlations of the time series of the suspended sediment concentrations in different regions in the surrounding waters, including the correlations between the construction regions and the sand excavation regions, were calculated. Our results indicated that the sand excavation north of the Pearl River Estuary had a limited impact on the surface suspended sediment concentrations in the Hong Kong-Zhuhai-Macau Bridge tunnel area.

Abstract:
A knowledge of bed shear stress induced by waves is required to understand dynamic processes of nearshore morphologies as a results of sediment transport. However, the information on the stress is still incomplete due to lack of measured data. The study analyzes the unsteady horizontally averaged shear stresses measured over mobile beds in a water tunnel. It is found from the analysis that the presence of the third and fifth harmonics in the shear stress is in good agreement with the measured concentration of suspended sediments.

Abstract:
The question of the arrangement of sound absorbers has been under study for some time. In our approach we conducted a sequence of experiments in a reverberation chamber to determine the optimal sound absorption for different configurations of suspended absorbers using various air spaces and a central dividing panel between them. The results obtained were compared with measurements of the panels, tested against a solid backing as specified in ISO-R-354. It is shown that a porous absorber is more efficient at high frequencies if it is suspended in the sound field rather than against a solid backing. It was also found that the efficiency of an air space between the two porous sheets that compose a suspended absorber is moderately increased when a central divider is used. The statistical precision of the test was also investigated.

Abstract:
The thermal conductivity of suspended graphene varies greatly under light, but the thermal conductivity of supported graphene does not change as much as that of suspended graphene. This is due to the fact that all of the loaded graphene is placed on the substrate and the thermal diffusivity of the loaded graphene is very good. In this paper, the ultrafast properties of supported graphene and suspended graphene have been studied. Suspended graphene has unique thermal conductivity, and its thermal conductivity will change greatly with the increase of temperature. Because of graphene has no band gap, the photon emission of supported graphene cannot be realized by electron hole recombination as in direct band gap materials. Optical emission of hot carriers is possible in graphene, but usually inefficient. That’s because most materials have much faster thermal carrier relaxation time than radiation lifetime. Herein, the hot carrier emission of suspended graphene and supported graphene are studied by femtosecond laser. It is found that the hot carrier can reduce the relaxation time of hot carrier in suspended structure. The suspension structure does increase the intensity of photon emission.

Abstract:
River ice breakup is known to be an important geomorphologic agent, creating numerous erosional and depositional features within river channels and on adjacent floodplains. Despite such evidence, information about the suspended sediment concentration and bed load during breakup is virtually nonexistent. Measurements of suspended sediment concentration were made during the 1987 breakup of the Liard River, N.W.T., Canada. Results showed a gradual rise during the pre-breakup period followed by an order of magnitude increase at the time of the major river-ice run. The ice-affected peak concentration of 1067 mg/L falls within the recorded range of annual open-water peaks that were produced by flow events of 2–5 times greater discharge. Key words: river ice, ice breakup, sediment, flood.

Abstract:
Although many cases of Campylobacter and Salmonella enteritis have been attributed to the undercooking of poultry and other foods, cross-contamination between raw and cooked foods via food contact surfaces and worker contact has also been identified as a significant risk factor. Cross-contamination may be particularly important in relation to the high prevalence of contamination in raw poultry products and other foods and the low infectious doses that have been reported for Campylobacter species. Lag phase and decimal reduction times (D-values at 27°C [81°F] and 60 to 62% relative humidity) were determined for Campylobacter jejuni and Salmonella species (five-strain pools) suspended in either a phosphate-buffered saline (PBS) solution or Trypticase soy broth (TSB) and then inoculated (0.1-ml drop per surface) on 5-cm2 samples of Formica laminate (F), glazed ceramic tile (CT), 304 polished stainless steel (SS), and 100% cotton dishcloth (D). Triplicate samples were collected from each contact surface periodically, and the populations of surviving organisms were enumerated on Campy Cefex and brain heart infusion agars for C. jejuni and Salmonella species, respectively. Lag time and rate of inactivation were influenced by organism type, contact surface, and suspending medium. Initial mean lag times ranging from 60 to 190 min were followed by log-linear (r2 &gt; 0.94) decreases in cell populations that varied across contact surfaces. D-values of 12.5, 19.1, 24.1, and 29.7 min and of 23.7, 10.5, 12.7, and 13.9 min were calculated for C. jejuni suspended in PBS and TSB and then spotted on D, F, SS, and CT surfaces, respectively. The times required to produce a 3-log reduction in population with PBS and TSB ranged from 102 (D) to 247 (F) min and from 112 (CT) to 167 (F) min, respectively. C. jejuni cells suspended in the nutritionally enriched medium (TSB) and spotted on the hard surfaces were inactivated about 1.4 times as fast as cells suspended in PBS. For the Salmonella test strains, D-values of 17.1, 426.6, 118.6, and 41.9 min and of 48.2, 1363.2, 481.8, and 134.2 min were calculated for cells suspended in PBS and TSB and then spotted on D, F, SS, and CT surfaces, respectively. In contrast to C. jejuni, Salmonella serotypes were 1.7 to 3.3 times more persistent when suspended in TSB than when suspended in PBS and were 1.2 to 25.3 times more persistent than C. jejuni, depending on the contact surface and the type of suspension fluid (i.e., overall time required to achieve a 3-log reduction in population, lag time + 3 × D). These findings indicate that both the contact surface and the level of organic matter can influence the survival and persistence of C. jejuni and Salmonella species on food contact surfaces.
