摘要：
Purpose Nowadays, the rapid growth of information technology strategies such as cloud computing is very noticeable in organizations. The advantages of the cloud environment are unavoidable because of an increase in innovation, flexibility and economy. Therefore, the critical topic is considering the factors affecting the adoption of cloud computing. This study aims to understand the factors of the adoption of cloud computing and its benefit in companies. Design/methodology/approach A research framework with four hypotheses has been developed based on the results of previous studies. Structural equation modeling has been used for data analysis. Findings The proposed model is verified by the results. In addition, the results have shown that cloud computing adoption is affected by four variables as follows, including human factor (with sub-indicator personal innovativeness and knowledge), organizational factor (with sub-indicator size, adequacy of resources and top management support), technical factor (with sub-indicator compatibility and security) and environmental factor (with sub-indicator regulatory environment, competitive pressure and trading partner). Research limitations/implications There are crucial implications in the findings: they have an essential contribution to the research community, administrators and Information and Communications Technology providers with respect to framing improved tactics for the adoption of cloud computing. The proposed model can enhance the perception of service providers about why some services sectors accept cloud computing amenities, whereas apparently the same ones having the same market situations do not. In addition, the above providers should enhance their interaction with the services sectors contributed to the cloud computing experience to make a well-organized setting for the adoption of cloud computing, and eliminate any ambiguity about this sort of technology. Moreover, the sample has been limited to Iran respondents. Practical implications The research studies about the usage of cloud computing have shown its effects on organizations today. Also, the different impacts of cloud computing on other contexts and organizations are in the center of attention. By carefully considering and managing cloud computing adoption logics, organizations could get significant advantages. Originality/value Cloud computing's technical and operational issues have been central in most of the previous studies. Some surveys have referred to the adoption of cloud computing by the organizations in terms of human characteristics or the contextual factor. Therefore, there should be a model and outline to assess the effect of aforesaid factors on cloud computing adoption.

摘要：
D151 resin preloaded with Fe(3+) [denoted as R-Fe(3+)] was to investigate R-Fe(3+) as an adsorbent for glyphosate from water in the presence high concentration of salt. The adsorption mechanism revealed the coordination of Fe(3+) inside R-Fe(3+) with O atoms of P-O and N atoms in glyphosate molecule. The adsorption capacity of glyphosate by R-Fe(3+) was much larger than that of D151 resin preloaded with Ni(2+), Cu(2+), Na(+) and H(+). Even in glyphosate solutions containing 16% NaCl, R-Fe(3+) showed the constant adsorption capacity of glyphosate. The result provided the fi rst evidence of R-Fe(3+) as a salt resistant adsorbent for glyphosate. The adsorption capacity of glyphosate was the maximum at pH 3.35. The adsorption thermodynamics showed that the adsorption of glyphosate by R-Fe(3+) was the ligand exchange of glyphosate and water. The maximum coordination ratio of glyphosate to Fe(3+) inside R-Fe(3+) was 1:1. The maximum adsorption capacity of glyphosate by R-Fe(3+) was up to 481.85 mg/g, which is much higher than that of other reported adsorbents in the presence 16% NaCl. 2 mol/L NaOH, 2 mol/L H2SO4 and 2 mol/L Fe2(SO4)3 could all be used to achieve over 97% regeneration of R-Fe(3+).

摘要：
The primary purpose of this paper is to analyze and predict the ground settlement law of large-span rectangular shield frame bridge jacking project, to provide a reference for the optimization design and safe construction of similar projects. In this paper, combined with the jacking project of ultra-shallow buried soft soil layer rectangular shield frame bridge, through the on-site monitoring, the settlement deformation law of the longitudinal and transverse sections of the expressway pavement during the jacking construction process is discussed, and the reasons for the large settlement and rebound are analyzed. The basic laws of the road surface settlement with time are summarized. Based on the Kriging spatiotemporal prediction model, the road surface settlement is predicted. The research shows that the transverse settlement trough of the pavement caused by the rectangular shield frame bridge's jacking construction is stable within 15 m-20 m on both sides toward the axis and symmetrical along the coordinate axis and the alignment roughly conforms to the normal distribution. The influence range of settlement trough becomes greater and greater with shield jacking, and the final settlement curve is W-shaped. After comparing the predicted curve with the measured road settlement curve, we found that the two curves are in good agreement, and the prediction result of the Kriging spatiotemporal prediction model is valid, which can reflect the process of road deformation development during the jacking process of the shield.

Ulcerative colitis (UC), as the main inflammatory disease in the colon, is regarded as one of the most refractory diseases by World Health Organization. Hydrogen peroxide (H2O2) is a kind of reactive oxygen species (ROS) and is closely associated with the development of UC. Unfortunately, there is no an excellent fluorescence probe was designed for monitoring H2O2 in UC mice. Herein, a near-infrared (NIR) fluorescence probe (DCX-B) with large stokes shift (158 nm) is designed and synthesized, which displays good sensitivity and selectivity toward H2O2. The probe itself is non-fluorescent because intramolecular charge transfer (ICT) effect is blocked by the borate ester group. After DCX-B reacting with H2O2, the ICT process is restored and a strong fluorescence signal is released. Meanwhile, the possible reaction mechanism of DCX-B towards H2O2 is studied and proved by HPLC, MS and DFT calculation. Due to the low cytotoxicity of the probe, it is successfully applied in the image of H2O2 in two cell lines (HCT116 and HepG2 cells). Furthermore, enlightened by the properties of NIR emission and large stokes shift, DCX-B has been applied in monitoring the dynamic change of H2O2 in the diagnosis and treatment of UC mice.
摘要：
Sandstone-mudstone particle mixture (SMPM) is one of the main materials, which has been widely used for filling in and around reservoirs for water conservation projects. During the periodic rising and falling of the water level, the fill material for the embankments, dam, and other waterfront features will also undergo drainage-saturation cycles. The deformation and coefficient of lateral pressure at rest K-0 may be affected by periodic saturation. In this study, a device is modified for testing the K-0 for gravel-soil under periodic saturation. In order to investigate the effects of periodic saturation on K-0, a series of experiments were performed for SMPM under different vertical stress and saturation cycling. K-0(N) values of SMPM containing 20% mudstone particles under periodic saturation were obtained. The results shows that the K-0(N) initially increased, but eventually reached a stable value with the increasing number of periodic saturation cycles. The magnitude of the coefficient increment was also found to be related to the stress condition. K-0(N) is a logarithmic function of the saturation cycling time. By calculating K-0(N) with the proposed empirical formula, the deformation and stress distribution of the SMPM filler in waterfront engineering works can be calculated with greater precision.
摘要：
Based on a beta-cyclodextrin (beta-CD) subject-object competition model, a simple and sensitive electrochemical aptamer sensor for the determination of tetracycline (TET) was fabricated. First, the TET aptamer modified with ferrocene (Fc) as a signal molecule was captured by beta-CD loaded onto the gold electrode. Subsequently, TET was added to the detection system, causing a binding event between the target and aptamer with strong affinity during which process the aptamer configuration was changed from the original upright linear state to an agglomeration structure, resulting in its departure from the electrode surface. Consequently, an "off-signal" was turned along with the presence of the target. The results indicated that the TET concentration had a linear response to the signal ranging from 0.01 to 100 nM and the accurate detection limit could reach as low as 0.008 nM (3 delta). The fabricated TET biosensor also showed outstanding detection specificity. Moreover, the suitability of the developed method was demonstrated in the determination of TET concentrations in different samples comprising water, milk, and bacteria culture medium, achieving acceptable recoveries for spiked samples ranging from 96.0 to 104.4%. This detection system was simple, economical, time-saving but remarkably sensitive, selective, and efficient, potentially rendering services in food safety screening and medical testing.

摘要：
Ratiometric fluorescent sensors are powerful tools for quantitative analyses. However, gold nano-clusters (AuNCs) as typical fluorophores in ratiometric sensors have some disadvantages, such as low luminous efficiency. In this study, a highly sensitive ratiometric fluorescence sensor was fabricated by the combination of AuNCs and fluorescein (FL), and the photonic crystals (PhCs) were used to selectively enhance the fluorescence intensity of AuNCs. This fluorescence sensor was used for the sensitive detection of acetylcholinesterase (AChE) and its inhibitor paraoxon. AChE can catalyze the hydrolysis of acetylthiocholine (ATCh) to form thiocholine (TCh), which can induce the fluorescence quenching of AuNCs while having no obvious influence on the fluorescence intensity of FL. AChE can be determined in the range from 0.1 to 25 mU mL-1 with a limit of detection (LOD) of 0.027 mU mL-1, and paraoxon can be determined in the range of 0.06 to 60 ng mL-1 with a LOD 0.025 ng mL-1. This method, as a new way to selectively improve the fluorescence signal of one of the fluorophores in the ratiometric sensor, would be a promising strategy for the sensitive determination of AChE and its inhibitor.
