Exceptional Visible‐Light‐Driven Cocatalyst‐Free Photocatalytic Activity of g‐C3N4 by Well Designed Nanocomposites with Plasmonic Au and SnO2

In this work, plasmonic Au/SnO2/g‐C3N4 (Au/SO/CN) nanocomposites have been successfully synthesized and applied in the H2 evolution as photocatalysts, which exhibit superior photocatalytic activities and favorable stability without any cocatalyst under visible‐light irradiation. The amount‐optimized 2Au/6SO/CN nanocomposite capable of producing approximately 770 μmol g−1 h−1 H2 gas under λ > 400 nm light illumination far surpasses the H2 gas output of SO/CN (130 μmol g−1), Au/CN (112 μmol g−1 h−1), and CN (11 μmol g−1 h−1) as a contrast. In addition, the photocatalytic activity of 2Au/6SO/CN maintains unchanged for 5 runs in 5 h. The enhanced photoactivity for H2 evolution is attributed to the prominently promoted photogenerated charge separation via the excited electron transfer from plasmonic Au (≈520 nm) and CN (470 nm > λ > 400 nm) to SO, as indicated by the surface photovoltage spectra, photoelectrochemical I–V curves, electrochemical impedance spectra, examination of formed hydroxyl radicals, and photocurrent action spectra. Moreover, the Kelvin probe test indicates that the newly aligned conduction band of SO in the fabricated 2Au/6SO/CN is indispensable to assist developing a proper energy platform for the photocatalytic H2 evolution. This work distinctly provides a feasible strategy to synthesize highly efficient plasmonic‐assisted CN‐based photocatalysts utilized for solar fuel production.
South Africa-China Relations: A Constructivist Perspective

The paper analyses South Africa-China relations emphasising how changing identities of the two countries since the 1940s define their outlook on critical issues such as human rights and democracy. Sino-South African relations are divided into three epochs. The first covers the Mao era; the second traverses the post-Mao era and the subsequent economic and modernization reforms up to the end of the Cold War; the third and current epoch roughly starts in 1994, after the establishment of democracy in South Africa. Constructivism is used as the theoretical framework to interpret the evolving South Africa-China relationship. This study adopted a qualitative approach. The outcome of the study is that changes in identity of these two nations have shaped their national interests. Thus, when countries share identities and interests - be they good or controversial – stable cooperation is possible among them. In this vein, constructivism concedes that shared or differing identities and interests among states can produce either cooperative or conflictual relations. This distinguishes constructivism from idealism, a theory under which it has often been subsumed.
Empatía hacia la pareja como mediador del efecto del apego en el perdón y el resentimiento

Attachment style is a constant predictor of forgiveness, and it has been suggested that empathy mediates such effect, despite it has been tested in some previous research, they only have used measures of empathy as a trait, and in some others they do not measure secure attachment, and consider forgiveness and resentment as the extremes of the same continuum. Based on these disjunctions, for this research we aimed to test the mediation role of empathy towards the romantic partner on the attachment style effect on forgiveness and resentment. The participants were 264 Mexican adults involved in a romantic relationship. Simple mediation models showed that empathy mediates the effects of secure attachment style, forgiveness, and resentment, but only when the models included empathic wisdom and/or perspective taking as mediators. Such findings contribute to an accurate understanding of the relationship between the variables.
Effect of Perioperative Coagulation Monitoring by Sonoclot on Short-Term Thrombosis in Pediatric Liver Transplantation

Background Sonoclot devices are used to monitor coagulation function in transplant patients. However, the appropriate value of Sonoclot parameters for reducing postoperative thrombosis in pediatric liver transplantation is not clear. Therefore, the aim of the study was to investigate the effect of coagulation monitoring by Sonoclot devices on early postoperative thrombosis after liver transplantation in children. Method The clinical data of 200 children with elective liver transplantation were collected. The effects of coagulation function monitoring by Sonoclot devices 1 h after ischemia-reperfusion on early thrombosis were analyzed. Receiver operating characteristic (ROC) analysis was used to obtain the sensitivity and cutoff value of Sonoclot parameters for the diagnosis of thrombosis. Results A total of 38 (19%) patients had thrombosis complications. 23 cases (11.5%) had postoperative hepatic artery thrombosis and 15 cases (7.5%) had portal vein and hepatic vein thrombosis. Sonoclot coagulation parameters included the following: for the thrombosis group & non-thrombosis group, whole blood activated clotting time (ACT): 178.5 ± 33.2 & 280.4 ± 58.6 (p < 0.05), clotting rate (CR): 12.4 ± 5.4 & 11.5 ± 5.7 (p > 0.05), and platelet function (PF): 3.0±1.4 & 2.6±1.1 (p>0.05). Univariate and multivariate analyses showed that ACT was an independent risk factor for postoperative thrombosis. ROC analysis found that the sensitivity of ACT for the diagnosis of postoperative thrombosis was 94.7%, and the ACT cutoff value to predict early postoperative thrombosis was 228.5 s. Conclusion ACT after ischemia-reperfusion was a risk factor for early postoperative thrombosis. It is recommended that ACT be maintained above 228.5 s to reduce postoperative thrombosis.Trial registrationApproval was obtained from the Ethics Committee of Tianjin First Center Hospital in China (Approval Number: 2016N0039KY), and written informed consent was obtained from eligible guardians. This study has been registered in clinical trial (ClinicalTrials.gov ID: ChiCTR1900026125). All processes were ethical.
Human Resource Management Systems and Work Engagement: Exploring the Impact of Employee Paternalistic Values

Organizations implement high-commitment human resource management (HRM) systems to increase work engagement as they provide employees with a sense of being looked after in the workplace. This relationship is rarely considered alongside the responsibility of management to look after employees beyond the workplace too in return for hard work and loyalty, as represented by paternalistic values. This study, therefore, investigates the effect of high-commitment HRM systems on work engagement, mediated by employees perceiving the HRM system to be distinctive, consistent, and consensual (i.e., a strong system), and moderated by employee belief in paternalistic values. Based on an empirical study of 384 employees, high-commitment HRM is found to increase work engagement as hypothesized. However, HRM system strength does not mediate this relationship as expected and instead is associated with lower levels of work engagement. When testing for the moderating effect of employee belief in paternalistic values, when this is low, high HRM system strength leads to lower levels of work engagement. These findings imply that strong HRM systems may be perceived as intrusive, as paternalism may be, for employees with low belief in paternalistic values.
ADVANCEMENT IN THE PRODUCTION OF ACTIVATED CARBON FROM BIOMASS USING MICROWAVE HEATING

An overview of recent advancement in the production of activated carbon (AC) from biomass using microwave heating is presented. The use of microwave heating method for the thermal conversion of biomass to useful products has been on the increase in the last decade because it offers fast and uniform heating, and a higher level of automation. The effects of process parameters (microwave power and radiation time, agent flow rate in physical activation and impregnation ratio in chemical activation) on the properties and adsorption capacity of the AC are reviewed. From the results reported in the literature, it can be seen that the influence of the preparation parameters on the adsorption capacity of the prepared AC followed the same pattern. In the physical activation process, microwave power and radiation time have more pronounce effects on the properties of the AC than the activation agent flow rate. Furthermore, the properties of the AC were found to be at their best when the process parameters are at the optimum values wether individually or collectively, and further increase in the process value beyond optimum value resulted in decrease in their adsorption capacity.
Competition and Coordination in the Mexican Retail Market for Gasoline

We document the following stylized facts for the Mexican retail market for gasoline using data for 2018-2019: (1) consumer prices adjust slower than wholesale prices; (2) more competition, in the form of a higher density of stations, implies lower markups and lower prices; and (3) more competition implies faster pass-through. However, we find geographical differences in the speed of pass-through that cannot be explained by differences in station density. We conjecture that coordination on high prices could be offsetting competitive pressure in some locations. We build a classifier that separates municipalities into two categories depending on whether the relative price concentration is on “high” prices or “low” prices. In the first type of municipalities, the price concentration is correlated positively with the price level and negatively with pass-through. For concentration in “low” prices the signs of the correlations are reversed.
A novel single-phase five-level transformer-less photovoltaic (PV) inverter

Multilevel inverters are preferred solutions for photovoltaic (PV) applications because of lower total harmonic distortion (THD), lower switching stress and lower electromagnetic interference (EMI). In order to reduce the leakage current in the single-phase low-power PV inverters, a five-level transformer-less inverter is proposed in this paper. A total of eleven switches are required, while six of them only withstand a quarter of the dc-bus voltage, so the costs for them are low. Another four switches are turned on or off at the power line cycle, the switching losses for them are ignored. In addition, the flying-capacitors (FCs) voltages are only a quarter of the dc-bus voltage, and they are balanced at the switching frequency, which further reduces the system investment. The experimental results based on a 1 kW prototype show that the proposed modulation strategy can balance the FCs voltages at Vdc/4 very well. And the leakage current can be reduced to about 27 mA under both active and reactive operations, which satisfies the VDE 0126-1-1 standard.
Hierarchy-NMS: Merging Candidate Bounding Boxes for Cerebrospinal Fluid Cell Image Segmentation

In this article, Hierarchy-Non Maximum Suppression (H-NMS) is proposed to fix the defects of general NMS algorithms in cerebrospinal fluid cell image segmentation. To cope with the confusion caused by the hierarchy of candidate bounding boxes in this scenario, a tree structure is built on the top of all bounding boxes and only leaf nodes are saved as the final output. The experimental results showed that H-NMS outperforms some variants of NMS in the cerebrospinal fluid cell image processing in both image segmentation and cell counting.

Copper(II) coordination properties of the Aβ(1–16)2 peptidomimetic: experimental evidence of intermolecular macrochelate complex species in the Aβ dimer

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the deposition of extracellular aggregates of amyloid-β peptides (Aβ). Different metal ions accumulate within amyloid deposits, which suggests an involvement of metal ions in AD pathogenesis. Cu(II)-induced Aβ neurotoxicity might result from changes in the coordination of the metal ion during Aβ oligomerization or from different peptide/metal ratios. Little is known on the Cu(II) complex with low-molecular-weight Aβ species. Here, we report our results on the Cu(II) coordination modes with a synthetic Aβ(1–16) dimer where the C-terminal 16Lys residue, of each peptide chain, is linked to a N,N-bis[(3-amino)propyl]glycine bearing a PEG moiety at the C-terminus. The formation of macrochelate complex species with the involvement of imidazole nitrogen donor atoms of His13 and His14, during copper(II) binding at physiological pH and low metal to peptide ratios, is observed.

Stochastic Models of Two-Species Chemical Oscillators: Fluctuation and Stability

Oscillatory chemical reactions are of significant i mportance in chemical and biological sciences. In the present pa per we have studied the oscillatory behaviours of two chemical reactions (o r oscillators). The first is the classical Lotka model of auto-catalytic chemica l reaction and the second is the limit cycle chemical reaction (Tri-molecular re action) due to Schnakenberg. Beside the deterministic behaviour of stability and bifurcation of the kinetic equations we have studied the stocha stic behaviours of fluctuation and stability of the model system under random perturbation which are always present in real conditions.
Evaluation of personal exposure to Polycyclic aromatic hydrocarbons (PAHs) in an integrated steel plant

Polycyclic aromatic hydrocarbons (PAHs) constitute a large class of organic compounds containing two or more condensed aromatic rings. They are formed during incomplete combustion or pyrolysis of organic material such as coal, wood, petroleum products and waste. During each formation process, and consequently in air, water, soil and food, PAHs are always present as a “class”, and never as individual compounds, in complex mixtures containing also other chemicals. In a workplace environment such as a coking plant, the evaluation of workers’ exposure to carcinogenic risk is very important. Currently, no national law provides safety limits for individual PAH; at the international level, ACGIH reference limit exist only for volatile products of tar and coal pitch, expressed TLV-TWA (0.2 mg·m-3). In order to evaluate the carcinogenic activity of a mixture of PAHs, it is possible to follow two ways. Since benzo(a)pyrene (BaP) is the most widely studied compound from a toxicological point of view and it is the most frequently evaluated compound in several matrices, it is possible to estimate the carcinogenic activity of a mixture of PAHs according to its content of a reference compound such as BaP. WHO used this methodology in 1987 to estimate the risk of lung cancer associated with inhalation exposure to mixtures of PAHs. Another approach is based on toxic equivalency factors, conceptually analogous to those used for the evaluation of attributable risk to mixtures of dioxins. Once note the carcinogenic power of individual PAHs compared to that of a reference compound (eg, BaP), their contribution can be normalized using the Toxicity Equivalence Factors BaPeq (TEF). Considering the toxicological significance of this class of compounds, representative sampling of the environmental status were made in an iron ore steel plant, in order to assess the personal exposure of workers employed, using sampling and measurement devices, able to represent the average situation of the work shift. Moreover, both approaches were used to assess the carcinogenic activity of environmental samples.

Effect of strontium substitution on the structural and magnetic properties of La1.8Sr0.2MMnO6 (M = Ni, Co)-layered manganites

ABSTRACT Sr-substituted perovskites, La1.8Sr0.2MMnO6 (M = Ni, Co), were synthesized using the solid-state reaction technique to present a systematic study on their morphological, structural and magnetic properties. The average grain size of the as-prepared La1.8Sr0.2NiMnO6 samples are in the range of 0.2–0.7 µm and those for La1.8Sr0.2CoMnO6 manganites are 0.1–2.8 μm, which is significantly less than that of unsubstituted La2NiMnO6 (LNMO) and La2CoMnO6 (LCMO) manganites. The XPS analysis enlightened about phase purity, binding energy and oxygen vacancy of La1.8Sr0.2MMnO6 manganites. The Sr-substituted LNMO has revealed a sharp ferromagnetic to paramagnetic phase transition at 160 ± 2 K, which is about 120 K less than that of parent LNMO. The Sr-substituted LCMO exhibited such a transition at 220 ± 2 K, which is 8 K less than that of parent LCMO. The temperature-dependent magnetization measurements suggest that the effect of Sr on the transition temperature in LNMO is more significant than that of LCMO.

Objective: To detect the positive rate of MyD88 l265p mutation in DLBCL patients, and analyze the correlation between MYD88 L265p mutation and DLBCL prognosis. Methods: In this study, 40 formalin fixed paraffin embedded tissue samples were collected from the pathology department of the Fourth Affiliated Hospital and the First Affiliated Hospital of Anhui Medical University from January 2017 to December 2019. The relationship between MYD88 L265p gene mutation and clinicopathological parameters of DLBCL, such as age, gender, Ann Arbor stage, site, B symptom, NCCN-IPI and IPI score, ECOG PS score, serum ferritin, β2-microglobulin and LDH levels were analyzed. Results: The positive rate of MYD88 L265p was 20% (8/40), 25.0% (6/24) in non GCB and 12.5% (2/16) in GCB. There were no significant differences in age, gender, location, extranodal invasion site, β2-microglobulin, serum ferritin and LDH between wild-type and mutant type of MYD88 gene, but had statistical significance with Han’s classification. MYD88 L265p gene mutation was associated with Ann Arbor stage, NCCN-IPI score and IPI score. Conclusion: MYD88 L265P mutation is closely related to the occurrence, development and prognosis of DLBCL. It is an adverse prognostic factor of DLBCL and may be used for the prognosis evaluation of DLBCL.
Folic Acid—Targeted Doxorubicin Drug Delivery System for Triple-Negative Breast Cancer Treatment

Triple-negative breast cancer (TNBC) is a highly aggressive type of cancer with limited therapeutic options. However, this type of cancer cells has shown overexpression of folate receptors, which bind with folic acid (FA) with high affinity. This feature can be used for targeting of nanocarriers, such as liposomes. In order to further examine the potential of increased efficacy by targeting the folate receptor, we prepared folate conjugated liposomes (DSPC/Chol/PEG/DSPE-PEG-FA) and loaded them with doxorubicin (DOX), an anticancer drug. For this, we first synthesized and verified the conjugate between FA and PEG-lipid (FA-PEG-lipid). After that, liposomes were prepared with thin film hydration method followed by probe sonication. Three different types of targeted liposomes having different concentrations of FA-PEG-lipid in their membranes (0.1 mol%, 0.5 mol%, and 1 mol%) were evaluated for their cytotoxicity (DOX-loaded liposomes) on MDA-MB-231 (epithelial human breast cancer cells), 4T1 (murine mammary carcinoma cells), and MCF7 (Human breast cancer cells); the two first are TNBC cells and overexpress FA receptor, the third does not. Cytotoxicity results proved that increasing amounts of FA on the surface of liposomes results in enhanced antitumor activity of liposomal-DOX in the case of the cancer cells, which overexpress the FA receptor.
