High-quality liquid phase-pulsed laser ablation graphene synthesis by flexible graphite exfoliation

This work reports a one-pot procedure of laser ablation on a graphite target in a liquid medium, based on the variation of different parameters such as target type, laser wavelength, and ablation medium, to obtain high-quality graphene nanosheets. The morphology of derived products was characterized by the field emission scanning electron microscopy (FE-SEM). Then, the morphology and structure of the optimized sample were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), ultraviolet-visible-near infrared (UV–vis-NIR) spectroscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). By controlling the laser ablation parameters, we were able to prepare micrometer-sized few-layer graphene nanosheets with mainly less than ten layers. Such synthesized graphene nanosheets were grown at the surface of a flexible graphite target, indicating many potential applications in fundamental research, electrochemical and as hydrophobic surfaces.
Improving the System of Historic and Cultural Heritage Protection Through Social Participation: Based on the Practice of Guangdong

The early historic and cultural heritage protection is regarded as the responsibility of the government, and is promoted by the government, protection experts, planners, and a few other elites. These bodies constitute a top-down historic and cultural heritage protection system based on their cultural consciousness. In the social transition of market-oriented reform and property right reform, due to the profit-driven demands of individuals, enterprise, and development-oriented government, the protection system was gradually differentiated and a lot of “protective development” practices emerged. With the advent of the post-industrial era, based on the need for cultural identity, the historic and cultural heritage protection began to get attention from third-party organizations, community residents, and even the public, who launched “bottom-up” social participation. Therefore, this paper, based on social governance theory, takes the development of civil cultural conservation organizations in Guangdong as the research object, explores how to construct a society participation network in Guangdong, and discusses the influence and limitation of the network in promoting the historic and cultural heritage protection. The paper puts forward the idea of improving the system of historic and cultural heritage protection through social participation.

硫化镉纳米晶的表面缺陷及钯修饰对光催化制氢性能的影响

化石能源的过度消耗以及由此带来的环境问题日渐突出,开发利用可再生新能源迫在眉睫,近年来氢气被认为是一种清洁替代能源。自从发现利用TiO_2光催化分解水制氢(PHER)以来,半导体光催化剂制氢技术的开发已经受到人们的极大关注。金属硫化物(这里主要指ds区和p区金属)一般拥有较窄的带宽以及合适的导带位置,对太阳光谱的响应较强。其中,CdS作为窄带隙半导体,其带隙为2.4eV,可以吸收520nm波长以下的可见光和紫外光,加之其导带位置远高于H~+/H_2反应电势,使得CdS成为PHER的优秀半导体材料之选。虽然CdS是一个优秀的光子捕获材料,但是其自身仅表现出有限的PHER活性,这是因为光生电子和空穴的快速复合使得其对光能的利用率很低,同时光腐蚀现象也制约着其快速发展。因此,延长光生电荷的寿命以及加快表面反应对其的消耗是提高CdS量子产率的关键。
容量反应性在循环衰竭患者中的研究进展

循环衰竭仍是临床最常见的急危重症,发生率与病死率一直居高不下,早期有效的液体复苏可以改善预后。但不同的患者对容量复苏的反应效果也存在差异,心肺功能不全的患者容量复苏后并不能增加其心输出量,反而会使其前负荷增加而诱发肺水肿,故评估容量反应性尤为重要。

Thermally Radiative Viscous Fluid Flow Over Curved Moving Surface in Darcy-Forchheimer Porous Space

A numerical analysis is developed for incompressible hydromagnetic viscous fluid passed through a curved stretching surface. Fluid saturated by porous space is bounded by curved surface. Term of porous medium is characterized by implementation of Darcy-Forchheimer theory. Adequate similarity variables are implemented to develop a system of non-linear ordinary differential system of equations, which govern the flow behavior. The impact of radiation constraint and Eckert number is incorporated in the energy equation. Numerical scheme based on RKF45 technique is implemented to solve the derived flow model. Prescribed heat flux (PHF) and prescribed surface temperature (PST) boundary conditions are utilized on temperature with Prescribed Surface Concentration (PSC) and Prescribed Mass Flux (PMF) on concentration. Flow behavior is discussed for both the slip and no-slip conditions. Dimensionless physical quantities are presented through graphs and tables.
Using fluorescence surrogates to track algogenic dissolved organic matter (AOM) during growth and coagulation/flocculation processes of green algae

Tracking the variation of the algogenic organic matter (AOM) released during the proliferation of green algae and subsequent treatment processes is crucial for constructing and optimizing control strategies. In this study, the potential of the spectroscopic tool was fully explored as a surrogate of AOM upon the cultivation of green algae and subsequent coagulation/flocculation (C/F) treatment processes using ZrCl_4 and Al_2(SO_4)_3. Fluorescence excitation emission matrix coupled with parallel factor analysis (EEM-PARAFAC) identified the presence of three independent fluorescent components in AOM, including protein-like (C1), fulvic-like (C2) and humic-like components (C3). Size exclusion chromatography (SEC) revealed that C1 in AOM was composed of large-sized proteins and aromatic amino acids. The individual components exhibited their unique characteristics with respect to the dynamic changes. C1 showed the highest correlation with AOM concentrations (R~2= 0.843) upon the C/F processes. C1 could also be suggested as an optical predictor for the formation of trihalomethanes upon the C/F processes. This study sheds a light for the potential application of the protein-like component (C1) as a practical surrogate to track the evolution of AOM in water treatment or wastewater reclamation systems involving Chlorella vulgaris green algae.
Microbial response to CaCO_3 application in an acid soil in southern China

Calcium carbonate (CaCO_3) application is widely used to ameliorate soil acidification. To counteract soil and bacterial community response to CaCO_3 application in an acidic paddy soil in southern China, a field experiment was conducted with four different dosages of CaCO_3 addition, 0, 2.25, 4.5 and 7.5 tons/ha, respectively. After one seasonal growth of rice, soil physicochemical properties, soil respiration and bacterial communities were investigated. Results showed that soil pH increased accordingly with increasing dose of CaCO_3 addition, and 7.5 tons/ha addition increased soil pH to neutral condition. Moderate dose of CaCO_3 application (4.5 tons/ha) significantly increased soil dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) content, enhanced soil respiration, while the excessive CaCO_3 application (7.5 tons/ha) decreased these soil properties. High-throughput sequencing results illustrated that moderate dose of CaCO_3 application increased the richness and alpha diversity of soil bacterial community. Compared with control, the relative abundance of Anaerolineaceae family belonging to Chloroflexi phylum increased by 38.7%, 35.4% and 24.5% under 2.25, 4.5 and 7.5 tons/ha treatments, respectively. Redundancy analysis (RDA) showed that soil pH was the most important factor shaping soil bacterial community. The results of this study suggest that proper dose of CaCO_3 additions to acid paddy soil in southern China could have positive effects on soil properties and bacterial community.
Characteristics of one-year observation of VOCs, NO_x, and O_3 at an urban site in Wuhan, China

A continuous online observation of ozone and its precursors (NO_x, VOCs) was carried out in central urbanWuhan from September 2016 to August 2017. The concentration levels of ozone, NO_x, VOCs and their variations in urban Wuhan were analyzed, as well as effects of VOCs on ozone photochemical generation and themain controlling factors for ozone production. During the observation period, the average concentrations of ozone and NO_x inWuhan was 22.63 and 30.14 ppbv, respectively, and the average concentration of VOCs was 32.61 ppbv (42.3%alkanes, 13.0% alkenes, 10.0% aromatics, 7.3% acetylene, 9.9% OVOCs, and 10.5% halohydrocarbons). Ozone concentration was higher in spring and summer as compared with autumn and winter, wheras VOCs and NO_x concentratios were lower in spring and summer but higher in autumn and winter. Aromatics and alkenes, two of VOCs species, showed the highest contributions to ozone formation potential inWuhan (35.7%alkenes, 35.4 aromatics, 17.5%alkanes, 8.6%OVOCs, 1.6% halogenated hydrocarbons, and 1.4% acetylene). Among all VOCs species, those with the highest contribution were ethylene, m-xylene, toluene, propylene and o-xylene. The contribution of these five compounds to the total ozone formation potential concentration was 43.90%. Ozone-controlling factors in Wuhan changed within one day; during the early morning hours (6:00–9:00), VOCs/NO_x was low, and ozone generation followed a VOCs-limited regime. However, during the peak time of ozone concentration (12:00–16:00), the ratio of VOCs/NO_x was relatively high, suggesting that ozone generation followed a NO_x-limited regime.
Enzalutamide: a new indication for nonmetastatic castration-resistant prostate cancer

PROSPER is an international Phase III trial demonstrating the beneficial role of enzalutamide, an androgen receptor antagonist, in prolonging metastasisfree survival in men with nonmetastatic castration-resistant prostate cancer. The trial showed that the median metastasis-free survival was 21.9 months longer for those treated with enzalutamide(36.6 months) compared to those treated with placebo(14.7 months). Enzalutamide also showed prolonged time to PSA progression,PSA response, and time to initiating additional antineoplastic therapy although overall survival is not yet reached. Enzalutamide is the second antiandrogen(next to apalutamide) that has gained the United States Food and Drug Administration(US FDA) label indication for use in the setting of nonmetastatic castration-resistant prostate cancer.
Resveratrol attenuates metabolic, sperm, and testicular changes in adult Wistar rats fed a diet rich in lipids and simple carbohydrates

High‑fat diets affect male reproduction and sexual function. Therefore, we evaluated the effects of prolonged resveratrol administration on the metabolic, sperm, and testicular parameters of rats fed a cafeteria diet. Male Wistar rats were divided at weaning into control(C, n = 20) and cafeteria(CAF, n = 16) groups. At 3 months, half of them were given daily supplementations of resveratrol(C‑R, n = 10; CAF‑R, n = 8) at a dosage of 30 mg kg–1 body mass for 2 months. Animals were killed at 5 months of age,and blood, spermatozoa, and testes were collected for further analysis. Data were analyzed by one‑way ANOVA, and P < 0.05 was considered statistically significant. The CAF diet promoted hyperglycemia(P < 0.0001), and treatment with resveratrol reversed this condition(P < 0.0001). The CAF diet reduced sperm viability and motility, while resveratrol improved these parameters(P < 0.05). Regarding testicular morphology, the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group(P = 0.0007). Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group. However, the CAF‑R showed an increase in cell proliferation rate compared with that of the untreated CAF group(P = 0.0024). Although it did not modify body mass, the consumption of a CAF diet promoted hyperglycemia, adverse testicular morphology remodeling, and abnormal sperm, which were attenuated by treatment with resveratrol, thus suggesting a protective effect of this antioxidant on spermatogenesis.
Development and validation of a screening instrument for cognitive fluctuation in patientswith neurocognitive disorder with Lewy bodies (NCDLB): the Mayo Fluctuations Scale-Thai version

Background Prevalence of neurocognitive disorder with Lewy bodies (NCDLB) is low in Asian populations, which may partially reflect its diagnostic difficulty. The Mayo Fluctuations Scale, a short questionnaire that evaluates cognitive fluctuation, has been shown to significantly differentiate NCDLB from Alzheimer's disease. Aim This study aimed to develop the Mayo Fluctuations Scale-Thai version and assess its validity to screen NCDLB in an elderly population. Methods The Mayo Fluctuations Scale was translated into Thai. The process involved back-translation, cross-cultural adaptation, field testing of the prefinal version, as well as final adjustments. From all patients attending the Psychiatric and Memory Clinic at Ramathibodi Hospital, 135 patients accompanied by their primary caregivers were included. Caregivers were interviewed by research assistants using a four-item scale, and psychiatrists determined patients' diagnosis based on the diagnostic and statistical manual of mental disorders (DSM)-5 criteria. Evaluations performed by psychiatrists and research assistants were blinded. Results Seventeen participants had been diagnosed with major NCDLB. At a cut-off score of 2 or over, the Mayo Fluctuations Scale exhibited excellent performance to differentiate major NCDLB from other major neurocognitive disorders (NCDs), with a sensitivity of 94.1% and a specificity of 71.4%, and acceptable performance to differentiate mild NCDLB from other mild NCDs, with a sensitivity of 60% and a specificity of 93.1%. Conclusion The Mayo Fluctuations Scale-Thai version is an excellent screening tool for major NCDLB and an acceptable tool that may be used with other additional tests for mild NCDLB. The tool is practical for use in memory and psychiatric clinics. Further validation studies in participants with other specific clinical conditions are required.
The Combination of Two Control Strategies for Series Hybrid Electric Vehicles

With most countries paying attention to the environment protection, hybrid electric vehicles have become a focus of automobile research and development due to the characteristics of energy saving and low emission. Power follower control strategy(PFCS) and DC-link voltage control strategy are two sorts of control strategies for series hybrid electric vehicles(HEVs). Combining those two control strategies is a new idea for control strategy of series hybrid electric vehicles. By tuning essential parameters which are the defined constants under DClink voltage control and under PFCS, the points of minimum mass of equivalent fuel consumption(EFC) corresponding to a series of variables are marked for worldwide harmonized light vehicles test procedure(WLTP). The fuel economy of series HEVs with the combination control schemes performs better compared with individual control scheme. The results show the effects of the combination control schemes for series HEVs driving in an urban environment.
Design of a Proportional-Integral-Derivative Controller for an Automatic Generation Control of Multi-area Power Thermal Systems Using Firefly Algorithm

Essentially, it is significant to supply the consumer with reliable and sufficient power. Since, power quality is measured by the consistency in frequency and power flow between control areas. Thus, in a power system operation and control, automatic generation control(AGC) plays a crucial role. In this paper, multi-area(Five areas: area 1, area 2, area 3, area 4 and area 5) reheat thermal power systems are considered with proportional-integral-derivative(PID) controller as a supplementary controller. Each area in the investigated power system is equipped with appropriate governor unit, turbine with reheater unit, generator and speed regulator unit. The PID controller parameters are optimized by considering nature bio-inspired firefly algorithm(FFA). The experimental results demonstrated the comparison of the proposed system performance(FFA-PID) with optimized PID controller based genetic algorithm(GAPID) and particle swarm optimization(PSO) technique(PSOPID) for the same investigated power system. The results proved the efficiency of employing the integral time absolute error(ITAE) cost function with one percent step load perturbation(1% SLP) in area 1. The proposed system based FFA achieved the least settling time compared to using the GA or the PSO algorithms, while, it attained good results with respect to the peak overshoot/undershoot. In addition, the FFA performance is improved with the increased number of iterations which outperformed the other optimization algorithms based controller.

Ascorbic acid synthesis and transportation capacity in old laying hens and the effects of dietary supplementation with ascorbic acid

Background:Laying hens over 75 weeks of age commonly show great declines in immunity and production performance.It is unclear whether these declines can be relieved by supplementing with ascorbic acid (AA) in feed.Two trials were conducted to investigate the synthesis and metabolism of AA in layers of different ages and the effects of dietary supplemental AA on the performance and the immune and antioxidant statuses of 78 weeks old hens.Methods:In Exp.1,equal numbers (24 hens) of 35 weeks old (Young) and 75 weeks old (Old) layers were fed the same diet without AA supplementation for 4 weeks.In Exp.2,360 healthy 78 weeks old laying hens were randomly assigned to 4 treatments (basal diet supplemented with 0,0.25,0.5,or 1 g AA/kg diet) in an 8-week feeding trial.Results:The old hens tended to have decreased L-gulonolactone oxidase (GLO) synthase activity in the kidney and liver than that of the young hens (P=0.07 and P=0.05,respectively).Compared with the young hens,the old hens had lower hepatic antioxidant capacity allowing for the lower thioredoxin (TXN),thioredoxin reductase (TXNR) and cytochrome b5 reductase (CYB5R) gene expression (P <0.05),whereas increased sodium-dependent vitamin C transporter (SVCT) 1 expression levels in the ileum and kidney and enhanced splenic and hepatic AA concentrations (P <0.05).Dietary supplementation with AA significantly decreased GLO enzyme activity but increased splenic AA concentration and anti-bovine serum albumin IgG levels (P <0.05) and tended to increase CD4~+T lymphocyte numbers (P=0.06) in serum.Supplementation of 0.25 g AA/kg diet significantly increased hepatic total antioxidant capacity (T-AOC,P <0.05) relative to the control group.Conclusions:Laying hens could synthesize AA in both the kidney and the liver,though the GLO enzyme activities were 100 times greater in kidneys than in livers.The old laying hens had greater absorption and reabsorption capacity and higher AA retention in some tissues that did the young hens.Dietary supplementation of AA can improve the health of old layers by enhancing immunity and antioxidant capacity.
Dynamics of methanogenesis,ruminal fermentation and fiber digestibility in ruminants following elimination of protozoa:a meta-analysis

Background:Ruminal microbes are vital to the conversion of lignocellulose-rich plant materials into nutrients for ruminants.Although protozoa play a key role in linking ruminal microbial networks,the contribution of protozoa to rumen fermentation remains controversial;therefore,this meta-analysis was conducted to quantitatively summarize the temporal dynamics of methanogenesis,ruminal volatile fatty acid (VFA) profiles and dietary fiber digestibility in ruminants following the elimination of protozoa (also termed defaunation).A total of 49 studies from 22 publications were evaluated.Results:The results revealed that defaunation reduced methane production and shifted ruminal VFA profiles to consist of more propionate and less acetate and butyrate,but with a reduced total VFA concentration and decreased dietary fiber digestibility.However,these effects were diminished linearly,at different rates,with time during the first few weeks after defaunation,and eventually reached relative stability.The acetate to propionate ratio and methane production were increased at 7 and 11 wk after defaunation,respectively.Conclusions:Elimination of protozoa initially shifted the rumen fermentation toward the production of more propionate and less methane,but eventually toward the production of less propionate and more methane over time.
