Investigation of Flocculation Characteristics in the Yangtze Estuary
Authors: Guo Chao , Jin Zhongwu , Zhou Yinjun 
Published: April 2023

The dynamic process of flocculation is crucial for the transport and fate of cohesive sediment and adherent nutrients, heavy metals and pollutants etc. In order to improve the understanding of sediment flocculation dynamics in the estuary, field surveys in the Yangtze Estuary and laboratory experiments with natural mixed sediment were conducted. In-situ observations showed that the mean floc diameters (DM) ranged from 14 to 95 μm, and there were significant temporal and vertical fluctuations within a tidal cycle and between spring-neap cycles. Both high and low slack waters had greater DM, and neap tide’s average floc size was determined to be 57% larger than spring tide. The fractal dimension of flocs in the YE was primarily between 1.5 and 2.1, and effective density of flocs declined as floc size increased. According to experimental findings, DM in the 7 PSU saltwater first increased with rising shear rate G below a threshold of G = 20–30 s−1, then decreased with additional increases in G. Turbulent shear rate plays a crucial role in altering floc structure. Flocs formed in large shear forces were more compacted and had higher fractal dimensions. These studies contribute to the understanding of fine sediment dynamics, and facilitate the researches on reservoir, port and waterway sedimentation and pollutant transportation etc.

The honest sound of physical effort
Authors: Anikin Andrey 
Published: April 2023

Acoustic correlates of physical effort are still poorly understood, even though effort is vocally communicated in a variety of contexts with crucial fitness consequences, including both confrontational and reproductive social interactions. In this study 33 lay participants spoke during a brief, but intense isometric hold (L-sit), first without any voice-related instructions, and then asked either to conceal their effort or to imitate it without actually performing the exercise. Listeners in two perceptual experiments then rated 383 recordings on perceived level of effort (n = 39 listeners) or categorized them as relaxed speech, actual effort, pretended effort, or concealed effort (n = 102 listeners). As expected, vocal effort increased compared to baseline, but the accompanying acoustic changes (increased loudness, pitch, and tense voice quality) were under voluntary control, so that they could be largely suppressed or imitated at will. In contrast, vocal tremor at approximately 10 Hz was most pronounced under actual load, and its experimental addition to relaxed baseline recordings created the impression of concealed effort. In sum, a brief episode of intense physical effort causes pronounced vocal changes, some of which are difficult to control. Listeners can thus estimate the true level of exertion, whether to judge the condition of their opponent in a fight or to monitor a partner’s investment into cooperative physical activities.

Authors: Cynthia Orumie, Ukamaka , Nvene Samuel 
Published: April 2023

This research effort used an upholstery factory as a case study to apply the idea of integer programming for an ideal model. In order to allocate limited and readily available material resources to competing products (Bed (6x6ft), Bed (6x4ft), Wardrobe (6x6ft), Wardrobe (6x4ft), Side Drawer, and Shoe Rack) in the furniture factory with a view to maximizing profit, the Revised Simplex method of solving linear programming and the branch and bound method of solving integer programming models were used in this study. The analysis was carried out with the help of the LINDO software version 6.1 using data containing the availability of materials, sales volume for each of the product types, machine and time it takes to complete the manufacturing process of each product type, as well as profit per unit of the product as collected from the factory. The outcome indicated that 38 units of the Bed (6x6ft), 10 units of the Wardrobe (6x4ft), and 0 units of the other products needed to be manufactured to make a monthly profit of no more than ₦1711700. From the result, it was observed that the Wardrobe (6x4ft) and Bed (6x6ft) contributed majorly to the profit, hence the recommendation that more of the Wardrobe (6x4ft) should be produced and sold for optimum profit.

Published: April 2023

AbstractMolybdenum disulfide (MoS2) is a promising electrocatalyst for hydrogen evolution reaction (HER). However, the exposed active edge sites of MoS2 are limited due to its intrinsic stacking property. Herein, a highly exposed MoS2 hybrid electrocatalyst is prepared by a confined strategy of the pores of a 2D metal‐organic framework (MOF). A low overpotential of 76 mV at 10 mA cm−2 and a Tafel slope of 73 mV dec−1 are achieved, which indicated greater efficiency than pristine MoS2. The denotative growth of MoS2 from the internal pore of 2D MOF on the surface effectively prevents its stacking and exposes much more active edge sites. Experimental results show that parts of Co are incorporated into MoS2, producing strong electronic interaction between Co and Mo atoms and accounting for the excellent HER activity of MoS2. This work demonstrates a confined strategy to prepare nanomaterials with highly exposed edge sites and enhanced intrinsic activity.

AbstractGlyphosate‐resistant (GR) alfalfa (Medicago sativa L.) has been widely adopted in the United States. Exceptional tolerance of GR alfalfa to glyphosate application has been reported as a strength of this technology; however, growers have recently reported potential crop injury under specific environmental conditions. The purpose of this study was to document and characterize the injury and determine best management practices for avoiding injury to GR alfalfa in the Intermountain West. The effects of glyphosate rate and application timing during various seasons were investigated at 24 sites over 5 years, measuring the impact on alfalfa crop height and biomass yield. Summer glyphosate applications did not injure alfalfa. However, spring applications reduced crop height at 76% of sites and biomass yield at 62% of sites. At responsive sites, low (869 g ae ha−1) and high (1739 g ae ha−1) glyphosate rates reduced yield by 0.53 and 1.06 Mg ha−1, respectively. Alfalfa treated with high rates in the late spring, when 15–20 cm tall, had mean yield reductions of 16%–17% compared with untreated alfalfa. These results suggest that glyphosate applications made at tall crop heights or high rates on GR alfalfa are more likely to reduce crop height and yield in the Intermountain West compared with earlier applications at lower rates. We recommend that spring applications using low glyphosate rates occur before alfalfa is 10 cm tall to mitigate the risk of injury. If a high glyphosate rate is necessary, then an application should be made before alfalfa is greater than 5 cm tall.

Published: April 2023

AbstractA novel layered magnesium phosphate (MgP) was synthesised from a MgO−P2O5‐choline chloride‐oxalic acid dihydrate system using an ionothermal approach. Single crystal samples of MgP were obtained following introduction of diethylamine (DEA) to the reaction system. Its structure revealed that both the layer and the sheets contained Mg octahedra. Interestingly, adding the layered material to lithium grease resulted in superior lubrication with higher load‐carrying, anti‐wear and friction reduction capacities compared with the typical lubricant MoS2; the PB value of base grease was increased from 353 to 1078 and 549 N, the wear scar diameter was decreased from 0.50 to 0.34 and 0.46 mm, and the friction coefficient was decreased from 0.082 to 0.056 and 0.075, respectively. We also discuss the lubrication mechanism of layered materials based on the crystal structure and resource endowment. The findings could assist the development of new high‐efficiency solid lubricants.

AbstractThe pathophysiological mechanism behind the link between antipsychotic drugs and sexual dysfunction is still unknown. The goal of this research is to compare the potential effects of antipsychotics on the male reproductive system. Fifty rats were randomly assigned into the five groups indicated: Control, Haloperidol, Risperidone, Quetiapine and Aripiprazole. Sperm parameters were significantly impaired in all antipsychotics‐treated groups. Haloperidol and Risperidone significantly decreased the level of testosterone. All antipsychotics had significantly reduced inhibin B level. A significant reduction was observed in SOD activity in all antipsychotics‐treated groups. While GSH levels diminished, MDA levels were rising in the Haloperidol and Risperidone groups. Also, the GSH level was significantly elevated in the Quetiapine and Aripiprazole groups. By causing oxidative stress and altering hormone levels, Haloperidol and Risperidone are damaging to male reproductivity. This study represents useful starting point for exploring further aspects of the underlying mechanisms reproductive toxicity of antipsychotics.

Microstructural Evolution of Zinc‐Ion Species from Aqueous to Hydrated Eutectic Electrolyte for Zn‐Ion Batteries

Published: April 2023

AbstractDespite their intrinsic safety and environmental friendliness, typical aqueous Zn‐ion rechargeable batteries have been struggling with poor reversibility and electrochemical stability. Hydrated eutectic electrolytes (HEEs) have been attracting extensive attention due to their appealing features of high designability and superior performances over typical aqueous electrolytes. However, an in‐depth understanding of unique microstructure in HEEs and the ensuing superior performances remains obscure, limiting the development of enhanced electrolytes. Herein, we demonstrate a distinct evolution path of Zn‐ion species from aqueous to superior hydrated eutectic electrolytes, which experience a special transition state enriched with H‐bonds between eutectic molecules. Complementary with the well‐studied reorganized solvation structure induced by short‐ranged salt‐solvent interaction, long‐range solvent‐solvent interactions arising from the H‐bond reorganizes the extended electrolyte microstructure, which in turn influences the cation diffusion mechanisms and interfacial reaction kinetics. Overall, we highlight the importance of ion species microstructural evolution in the rational design of superior aqueous electrolytes.

AbstractObjectiveTo evaluate the changes of cervical soluble immune markers after focused ultrasound (FU) treatment to explore the underlying local immune effects of FU in the treatment of high‐risk human papillomavirus (HR‐HPV) infection–related low‐grade squamous intraepithelial lesion (LSIL).MethodsA total of 35 patients diagnosed with HR‐HPV infection–related histological LSIL who met the inclusion criteria were enrolled in this prospective study and treated with FU. The authors used cytometric bead array to measure T‐helper type 1 (Th1) cytokine (interleukin [IL] 2, tumor necrosis factor, and interferon γ) and Th2 cytokine (IL‐4, IL‐5, IL‐6, and IL‐10) levels in the cervicovaginal lavage of patients before and 3 months after FU treatment.ResultsAfter FU treatment, the concentrations of Th2 cytokines IL‐5 and IL‐6 were significantly lower than those before FU treatment (P = 0.044 and P = 0.028, respectively). HR‐HPV infection was cleared in 27 patients, with a clearance rate of 77.1% (27 of 35). The concentration of IL‐4 in patients with HR‐HPV clearance after FU treatment was significantly lower than that in patients without HR‐HPV clearance (P = 0.045).ConclusionFU can inhibit the production of certain Th2 cytokines and may improve the local immune status of the cervix, thereby eliminating HR‐HPV infection.
Pricing and corporate social responsibility investment strategies for a manufacturer under information asymmetry
Authors: Lv Fei 
Published: April 2023

AbstractWe consider a supply chain comprising a dominant manufacturer and a supplier where both firms are socially concerned. The corporate social responsibility (CSR) cost of the supplier is private information. The manufacturer can determine its sales price before the supplier starts production (committed pricing) or postpone its pricing decision until after receiving components from the supplier (noncommitted pricing). Moreover, the manufacturer can determine its CSR investment level before (ex ante CSR investment) or after (ex post CSR investment) the supplier. Four scenarios are investigated to examine the optimal pricing and CSR investment strategies of the manufacturer. We find the following: First, under a noncommitted pricing strategy, the manufacturer always prefers ex post CSR investment. However, the reverse holds under the committed pricing strategy. Second, under the ex post CSR investment strategy, committed pricing benefits the manufacturer for most parameter combinations whereas noncommitted pricing benefits the manufacturer when facing consumers with high CSR awareness and low price awareness. Under the ex ante CSR investment strategy, the manufacturer always prefers committed pricing. Finally, the joint committed pricing with ex ante CSR investment strategy is optimal for the manufacturer.
