Graphitic-Phase C3N4 Nanosheets Combined with MnO2 Nanosheets for Sensitive Fluorescence Quenching Detection of Parathion-Methyl

In this study, we have developed a sensitive approach to measure organophosphorus pesticides (OPs) using graphitic-phase C3N4 nanosheets (g-C3N4) combined with a nanomaterial-based quencher MnO2 nanosheets (MnO2 NS). Because MnO2 NS could quench the fluorescence of g-C3N4 via the inner-filter effect (IFE), the enzymatic hydrolysate (thiocholine, TCh) can efficiently trigger the decomposition of MnO2 nanosheets in the presence of acetylcholinesterase (AChE) and acetylthiocholine, resulting in the fluorescence recovery of g-C3N4. OPs, as inhibitors for AChE activity, can prevent the generation of TCh and decomposition of MnO2 nanosheets, accompanied by fluorescence quenching again. So the AChE-ATCh-MnO2-g-C3N4 system can be utilized to detect OPs quantitatively based on the g-C3N4 fluorescence. Under the optimum conditions, the linear range for the determination of parathion-methyl (PM) and 2,2-dichlorovinyl dimethyl phosphate (DDVP) were found in the range of 0.1-2.1 ng/mL with a limit of detection of 0.069 ng/mL, and 0.5-16 ng/mL with a limit of detection of 0.069 ng/mL, respectively. Finally, this method was exploited for the monitoring of PM in real samples. The advantages of the assay are user-friendly, easy-to-ease, cost-effective compared to sophisticated analytical instruments.
Effectiveness in Group Facilitation Training in the Hospitality Industry: A Case Study

ions they make out of the training, or “theories”, are the basis for the definition of further behavior and attitudes, as explained by Kelly in his personal construct theory (Kelly, 1963). These managers may be competent in team leadership (push approach), however not forceful in using a facilitative style of group EFFECTIVENESS IN GROUP FACILITATION TRAINING IN THE HOSPITALITY 43 coordination (pull approach), either with small-group or large-group facilitation. Nevertheless, by challenging their previous experience, the course produced better results than if they had to experience at all. A particular added value of the course turned out to be the innovation projects that came out of the forum. Even if not planned to have a material output, the course served to demonstrate a methodology that provided innovative results and, we may assume, participants will use some of it in their daily work. If not in large group meetings (managers complained that it is not possible to assemble workers for hours, given the labor-intensive regime in the hotel industry), at least with smaller project teams it is expected that some kind of matrix structure, made out of innovation projects, may arise. This prevision, also supported by participants’ evaluations, was not possible to verify, as the hotel industry had to shut down because of the Corona virus. Let us hope that, in the near future, the industry may regain its place also by providing the required innovation for completely new conditions. If this is so, the course will have played its role. As a final conclusion, we can say that the course model we provided for the preparation of managers as coaches for organizational innovation in the hospitality industry proved to be adequate. Although it requires changes in the introduction, and elimination of abstract examples, its structure proved to be adequate. As to future developments, they will have to do mostly with the functioning of a matrix structure, so that the whole approach may have a full impact on the company. That is why this course should take place in companies that already have some initiatives in project development. If we succeed in bringing in the necessary expertise in human resource management, in matrix structures, we will have developed conditions to present an organizational behavior course syllabus, for managers and management students, which has proved to be effective. As to the hotel industry, the reduction of its limitations to expand project development, due to its labor-intensive nature, will continue to dictate its ability to produce innovations that are not adopted from elsewhere. In the post-COVID 19 era, where collaboration will dictate much of the changes (Chesbrough, 2020), this cannot help but take place.
Routability Optimization for Extreme Aspect Ratio Design Using Convolutional Neural Network

Circuits that are placed with very low (or high) aspect ratio are susceptible to routing overflows. Such designs are difficult to close and usually end up with larger area with low area utilization. We observe that non-uniform setting of utilization target greatly helps in these designs, specifically low utilization in the center and gradually higher utilization toward the ends. We introduce a convolutional neural network (CNN) model to predict the setting of utilization target values. Experiments indicate that routing congestion overflows are reduced by 29% on average of test designs with 40% reduction in wirelength.
Gender and Age Differences in Socio‐economic Inequalities in Total and Avoidable Mortality in Portugal: A Trend Analysis*

The purpose of this paper is to analyse how socio-economic inequalities in mortality (total and avoidable) evolved in Portugal from the 1990s onwards by looking at differences by gender, age group, poverty and cause of death. Results show that mortality in younger age groups is decreasing faster in the most deprived municipalities. Yet, avoidable deaths do not follow this pattern, particularly with respect to treatable mortality amenable to the health care services. Although total and avoidable mortality are decreasing across all age groups and both genders, decreases in treatable deaths during and after the 2011–14 economic crisis slowed down among the young, with a sharpening of socio-economic inequalities in avoidable mortality among adults and the elderly. This provides evidence that, in some respects, focusing programmes on those living in poor circumstances has been successful over
New sesquiterpenoids from the rhizomes of Atractylodes macrocephala

Three new sesquiterpenoids, atractylenolide V, Atractylenolide VI and Atractylenolide VII, together with four known sesqiterpenoids were isolated from the rhizomes of Atractylodes macrocephala. Their structures were established on the basis of spectral evidence.
COMPARISON OF THE EFFECTIVENESS ONLINE AND OFFLINE REGISTRATION SYSTEM ON PATIENT WAITING TIME IN PRIMARY HEALTH CARE SEMARANG USING QUEUING THEORY

The online registration system at Semarang's Primary Health Care has been implemented in 2018, but online registration users are still small. The purpose of this study was to compare the effectiveness of online and offline registration at waiting times using variables in queuing theory. Research at 3 health centers in the city of Semarang. By observing the time of arrival and time of admission to the patient's clinic then the patient is also given a registration service satisfaction questionnaire sheet. The data were processed using queuing theory variables as well as descriptive and inferential statistical analysis. The number of online registrants is only 12% while 88% registered offline. The total number of online registrant patient arrivals per hour is 0.85 patients and offline registrants are 6.38 patients per hour where many patients arrive at the first 105 minutes to open the puskesmas. The utility of the online registrant registration server is 7%, while 48% offline is classified as low and the patient queue is only about 1 patient so there is no need for an additional registration server to speed up service. There was a difference between online and offline registration waiting times (p = 0.00) where online patients waited 4.91 minutes while offline patients waited 8.84 minutes. There is an effect of waiting time in the system on patient satisfaction (p = 0.00) so that to increase patient satisfaction, it is hoped that patients will register online.
Fabrication of Au Nanowire/Pichia pastoris Cell Composites with Hexadecyltrimethylammonium Bromides as a Platform for SERS Detection: A Microorganism-Mediated Approach

Au nanowire/Pichia pastoris cell composites were prepared using a microorganism-mediated method, where closely packed Au nanowires (AuNWs) are synthesized at high yields in the presence of hexadecyltrimethylammonium bromide (CTAB) without auxiliary seeds. The initial concentrations of ascorbic acid (AA), CTAB, and tetrachloroaurate trihydrate, as well as the amount of Pichia pastoris cells (PPCs), were optimized for the formation of AuNWs. For the formation of AuNWs, Au(III) ions were initially bound by the PPCs and then reduced by AA to produce Au nanoparticles (AuNPs) via preferential nucleation. The linear fusion of these AuNPs influenced by CTAB resulted in the formation of growing AuNWs, whereas the secondary nucleation beyond the PPCs produced small AuNPs that were subsequently consumed through Ostwald ripening during the aging of AuNWs. These AuNW/PPCs composites could be effectively used as surface-enhanced Raman scattering substrates for the detection of rhodamine 6G.
N-sided Irregular Polygonal Cavity Camouflage Coating with Homogeneous Parameters

Based on transformation optics theory, a kind of N-sided irregular polygonal cavity camouflage coating is proposed in this paper. The constitutive tensors of the camouflage coating are derived, and the functionality of the proposed coating is validated by full wave simulations. Simulation results show that the designed camouflage coating all has the same near and far field distributions with that of the bare PEC cavity in different incident angles and directions. In addition, this approach can be further to design N-sided irregular polygonal ground plane cloak with homogeneously anisotropic parameters. In order to apply at optical wavelength, the performance of the nonmagnetic camouflage coating is also verified. The simulations show that the reflective fields of nonmagnetic camouflage coating well agree with that of ideal coating except for incident direction because of the boundary impedance mismatching. Since the parameters of the designed camouflage coating are homogeneously anisotropic, it is expected that the proposed camouflage coating may find potential applications in the electromagnetic field engineering.
Treatment of Infectious Mononucleosis with High Dose Vitamin D3 in Three Cases

Infectious mononucleosis often results in significant morbidity and disability lasting up to six months. It is known that vitamin D induces cathelicidin production that can rapidly responds to some viral, bacterial and fungal infections. The Epstein Barr virus is able to block the vitamin D receptor thus blocking the ability to fight this infection. This article presents three cases, which responded quickly to loading doses of vitamin D (150,000-200,000 IU) followed by a month of 10,000IU daily.
Comparative Evaluation of Saliva and Serum Proteins in Diabetics and Normo-Glycemics

One of the most probable markers of inflammatory response is serum protein. Recently, serum levels of these some proteins have been proven to be useful in clinical diagnosis. In this study, we comparatively investigated serum and saliva C - reactive protein (CRP), α-amylase and α-glucosidase activities in type II Diabetic and Normo-glycemic humans. Two hundred and thirteen (213) subjects of 173 Diabetics and 40 Non-diabetics (Control) were ethically recruited from the central hospital, warri, Delta State. For each participant, serum and saliva was collected and laboratorily analyzed for α-amylase, α-glucosidase and CRP levels, while comparing mean differences between groups with a student t-test and statistical measure of association (correlation). Result showed a statistically significant increase in CRP and α-amylase activity of diabetics than non-diabetic subjects, with a statistically significant increase in salivary and serum CRP, α-glucosidase and α-amylase levels across groups. This finding is suggestive that saliva and/or serum levels may be useful bioanalytes for non-invasive, alternative diagnosis of blood glucose levels. Similar studies that corroborate the efforts of this study is recommended. Further studies that assay other saliva and serum biomarkers may also be useful and thus recommended.
Rhenium distribution and behaviour in the salinity gradient of a highly stratified estuary and pristine riverine waters

The abundance and distribution of dissolved Re (DRe) has been determined in the freshwater part of the Krka River (Croatia), draining the karstic carbonate landscape, as well as in the salinity gradient of its highly stratified estuary. Due to low DRe concentration, the batch procedure consisting of pre-concentration step using an anion exchange resin (Dovex) and analysis of DRe in 8 M HNO 3 eluate using a high resolution inductively coupled plasma mass spectrometry (HR ICP-MS) was adopted. Due to the potential inconsistent recoveries, ranging from 60% to 87%, the quantification was performed by using the isotope dilution (ID) technique. The DRe concentration in the Krka River basically increased in the downstream direction, with the 6.2 pM at the spring site, reaching 11.9 pM before the estuarine region. The weathering of the surrounding carbonate lithology is assumed as the source of natural Re. The two specific anomalies were registered: a strong increase in DRe concentration due to the anthropogenic input near the town of Knin (27.5 pM) and a decrease at downstream site caused by the subterranean input of freshwater of the Zrmanja River leading to relatively low DRe concentration (8.5 pM). In the estuarine segment, a near-conservative behavior of DRe was found in the salinity gradient of the upper surface layer, with the DRe concentration ranging from 18 to 38 pM. An anthropogenic supply was suggested within the estuarine segment close to the urban area causing a small positive deviation from the conservative line. In the bottom seawater layer, a minor decrease of DRe concentration in the most upstream estuarine regions was evidenced, implying a potential weak scavenging of Re.
Reflection and Absorption Spectra of Silver Nanocubes on a Dielectric Substrate: Anisotropy, Angle, and Polarization Dependencies

Angle and polarization dependent UV–visible reflection and transmission spectra were measured for monolayers of weakly interacting silver nanocubes (of 40 and 80 nm edge lengths) supported by thin films of titanium oxide on glass utilizing both front and rear geometries with respect to the incident radiation. The supporting substrate mediates the hybridization of dipolar and quadrupolar plasmon resonances. From the spectra absolute extinction and absorption cross sections for supported silver nanocubes were determined. A strong angle dependence of the extinction and reflection spectra for p- but not s-polarized light was observed. This dependence is considerably more pronounced for the hybridized quadrupolar resonance of the 40 nm cubes. When illuminated from the rear, a significantly stronger absorption of light by the dipolar but not the quadrupolar resonance occurs for both cube sizes. Such absorption anisotropy could result from the wavelength dependent constructive or destructive interference between.
An Energy-Efficient Level Shifter Using Time Borrowing Technique for Ultra Wide Voltage Conversion from Sub-200mV to 3.0V

Level converting is increasingly difficult in ultra-low voltage circuits with the aggressive scaling down of the input voltage. In this paper, we proposed a wide output range level shifter (LS) with the ultra-low input voltage. The proposed LS is integrated with a positive flip-flop function with a three-phase time borrowing scheme at the sampling edge. The working principle eliminates the current contention problem in the conventional cross-coupled level shifters, which allows a much higher output range at ultra-low input. The time borrowing technique also allows a relaxed timing constraint, which increases the timing margin and improves robustness against variation in ultra-low voltage circuits. The proposed LS is implemented with 45nm CMOS technology. Simulation results show that the proposed structure achieves a propagation delay of 10.01ns, power consumption of 11.23pW, and a power-delay-product (PDP) of 112,412ns-nW when converting an input signal of 200mV to an output level of 3 V.
Frontiers in Dentistry

Article type: Original Article Objectives: The aim of this study was to evaluate the influence of varying dentin and enamel layer thicknesses of two nano-composite resins on color match of composite resins and lithium disilicate dental ceramic. Materials and Methods: Twenty-six specimens of two types of nano-composite resins, Opallis and Vittra, were fabricated using the two-layered technique with different thickness ratios of enamel and dentin composites (A2 shade) with a total thickness of 1.2mm. Thirteen discs of the same shade and thickness of IPS e.max Press LT (low translucency) lithium disilicate dental ceramic were also fabricated. Specimen color was measured with a spectrophotometer. The difference in color (ΔE00) of composite and ceramic specimens, and the translucency parameter (TP) of all specimens were calculated. Data were analyzed using multi-factor ANOVA (P<0.05). Results: The color difference (ΔE00) values of composites and ceramic were not clinically acceptable in any areas of either of the two composites (ΔE00>2.25). But ΔE00 between the two composite resins was in the clinically acceptable range (ΔE00<2.25). The mean TP value of IPS e.max Press was greater than that of Vittra and lower than that of Opallis. Conclusion: In similar thicknesses, composite resins with any enamel/dentin thickness ratio could not successfully simulate the color and translucency of IPS e.max Press LT ceramic.
JCa2Co: A joint cascade convolution coding network based on fuzzy regional characteristics for infrared and visible image fusion

To facilitate the extraction of source image information, and preserve the consistency of heterogeneous regional features, a multiscale image fusion method based on a joint cascaded convolutional coding network (JCa2Co) is proposed. The JCa2Co network can retain vast quantities of information from source images in a multiscale perspective. The approach includes an encoder, a fusion layer and decoder. In the fusion layer, the Fuzzy Regional Characteristics (FRC) scheme is considered, and the multiscale feature maps are extracted from image subregions to ensure regional image consistency. Firstly, a joint cascaded encoder is used to extract multiscale features of the source image, in which the output of each layer is connected to every other layer. The fusion layer based on FRC is then performed to fuse each scale feature. Finally, the fused image is reconstructed by the decoder. In addition, to verify the regional consistency of the fused image, a regional consistency measure is proposed. Experiments are performed on the TNO Image Fusion Database. The experimental results exhibit that the proposed JCa2Co method has better comprehensive performance than the eight state
Effect of Visitor Number on the Behavior and Cortisol Metabolites Concentrations of Sambar Deer (Cervus unicolor) in Captivity

The effect of the visitor on animal behavior in captivity has been widely reported. However, whether this visitor-effect also influences stress for captive animals is still limited and absent for captive Sambar deer (Cervus unicolor). Therefore, the objective of this study was to examine the effect of visitor numbers on the behavior and cortisol metabolites concentrations in captive Sambar deer. This study used 8 Sambar deer living in the Taman Rusa Lamtanjong, Aceh Besar. In total, 640 hours of behavior data were collected using focal animal sampling during two-month observations. During behavioral observations, the number of visitors to the Sambar deer cage was recorded and 35 fecal samples were collected. Fecal samples were then extracted and measured the cortisol metabolite concentration using a specific antibody, 11ßhydroxy-etiocholanolone, through an enzyme-linked immunosorbent assay (ELISA) method. Data were analyzed using a paired sample t-test and Spearman Rank correlation. The concentrations of cortisol metabolites were significantly higher when the presence of human visitors (301.06±37.21 ng/g feces) compared to the absence of human visitors (202.15±88.07 ng/g feces) in the cage (p<0.01). In addition, the number of visitors was significantly correlated with the increase of cortisol metabolites concentrations ( rs =0.510, p <0.01). Moreover, the presence of human visitors influences the animal behaviors particularly decrease the feeding activity (rs= -0.232, p<0.05), and increase the foraging (rs=0.263, p<0.05) and grooming (rs=0.355, p<0.01) activities. In conclusion, the number of visitors affected the increases of cortisol metabolites concentrations and influences some of the animal behaviors.
Preference between Individual Products and Bundles: Effects of Complementary, Price, and Discount Level in Portugal

This paper aims to (1) compare consumers’ preferences between individual products and bundles as well as (2) investigate some of the factors involved in bundle characteristics that may affect consumer’s preferences. Those factors are complementarity, price level, and discount level. An online survey developed by means of questionnaires were collected from the Portuguese population. Student’s t-tests were used to test the hypothesis formulated and to analyze the consumers’ preferences. The findings corroborate that in a scenario where the bundle does not offer any discounts, preference of individual products is higher. When a 20% discount is assigned to bundles, the overall preference for individual products is still superior. By offering a discount level of 45%, the overall preference for bundles becomes higher. The positive effect of complementarity bundles valuation is confirmed. This is the first approach to evaluate the preferences between bundles and individual products in the Portuguese market. The findings contribute to clarify the customer map within a Business Model Canvas. Furthermore, this paper analyzes the bundle complementarity and discount level effects simultaneously.
Rapid and Reversible Tuning of Structural Color of a Hydrogel over the Entire Visible Spectrum by Mechanical Stimulation

In this work, we report a rubberlike elastic hydrogel containing microdomains of bilayers periodically stacked into the polymer network that satisfy the Bragg’s law of diffraction. The rubberlike elastic hydrogel has been synthesized by applying double network principle into a viscoelastic hydrogel containing single-domain macroscopic lamellar bilayer. The hydrogel is able to tune the magnificent structural color reversibly over the entire wavelength range of visible spectrum as fast as the uniaxial tensile stretching and compressive deformation are applied and released. Owing to the strength, softness, and rubberlike elastic deformability, the tunable hydrogel can be used extensively to design a new class of soft tactile sensor as an advanced stress sensor that is able to detect a local deformation of a complicated force field.
