Investigation on properties of aqueous foams stabilized by aliphatic alcohols and polypropylene glycol

Abstract Foams stabilized by nonionic surfactants are usually moderately stable due to high drainage rate and intense bubble coalescence and coarsening. This study aimed to investigate comparatively the foam properties of aliphatic alcohols (methyl isobutyl carbinol (MIBC) and 2-octanol) and polypropylene glycol (PPG400). Experiments were conducted using the FoamScan method at various surfactant concentrations and gas flow rates where the foam volume, liquid content of foam and foam half-life were determined. The results showed that both foamability and foam stability of surfactant solution increased with increasing gas flow rate and surfactant concentration for all tested surfactants. PPG400 was an unusually strong surfactant having the largest surface activity compared with MIBC and 2-octanol, which exhibited the maximum foaming performance and foam stability at all tested gas flow rates and concentrations. The present study suggested that foam properties depended primarily on the type of surfactant and its concentration and secondarily on the gas flow rate. In addition, properties of interface are closely related to that of foam, which is a significant point if one wants to produce foams for specific applications. Graphical Abstract
Stress and the Well-being of Nurses: an Investigation using the Demands-Resources- Individual Effects (DRIVE) model and the Well-being Process Questionnaire (WPQ).

Previous research shows that nurses have high levels of stress, but less is known about their well-being. The present research used an adapted version of the Demands-Resources-Individual Effects (DRIVE) model to investigate these areas. The Well-Being Process Questionnaire (WPQ), which consists of single items derived from longer scales, was also used. One hundred and seventy-seven British nurses (160 female, 17 male) participated in an online survey. The results showed that work characteristics could be grouped into three factors (resources; demands; and role/change/bullying), as were personality scores (positive personality; openness, agreeable, conscientious; and extraversion, emotional stability). Coping (positive and negative coping) and outcomes (positive and negative outcomes, and positive and negative job appraisals) had a two-factor solution. Results from logistic regressions showed that well-being outcomes were predicted by high positive personality and low negative coping. Positive job appraisals were predicted by high resources and low demands. These findings confirm that the use of the DRIVE model and a single short item measuring instrument can quickly provide information about factors predicting the well-being of nurses.
Experimental dimensions and precision in trials with millet and showy rattlebox

: The objective of this study was to determine the optimal plot size to evaluate the mass of fresh matter in millet ( Pennisetum glaucum L.) and showy rattlebox ( Crotalaria spectabilis Roth.), in scenarios formed by combinations of treatment numbers, repetitions numbers, and levels of experimental precision. Fifteen uniformity trials with millet and showy rattlebox, in single or intercropping, were carried out. The mass of fresh matter was evaluated in 540 basic experimental units (BEU) of 1 × 1 m (15 trials × 36 BEU per trial). The heterogeneity index of Smith (1938) was estimated. The plot size was determined by the method of Hatheway (1961) in scenarios formed by combinations of i treatments (i = 5, 10, 15, 20, and 25), r repetitions (r = 3, 4, 5, 6, 7, 8, 9, and 10), and d precision levels (d = 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20%). To evaluate the mass of fresh matter of millet and showy rattlebox, in single or intercropping, with 5 to 25 treatments and with five repetitions, plots of 10 m² of useful area are sufficient for differences between treatments of 9% of the overall average of the experiment to be considered significant at 0.05 probability .
Design and Realization of an Inductive Power Transfer for Shuttles in Automated Warehouses

The inductive power transfer (IPT) is expected to greatly contribute towards electrification in transportation. In fact, IPT charging technology has the potential to overcome several limitations of conductive charging: in particular, the process can be fully automatable, and both static and dynamic charging are allowed, thus reducing the size of the battery pack. Additionally, safety is increased due to the absence of safety issues related to loss of cable insulation or to the unwanted interruption of the plug-socket connection. This paper presents, from a systematic approach, the design and realization of a prototype for IPT charging of autonomous shuttles in automated warehouses. First of all, the typical mission profile of the shuttle was properly identified, and a storage system based on power-oriented electrochemical cells was sized. Based on that, the architecture of the IPT system was chosen, both for transmitting and receiving sections. The pads were designed for this purpose, by considering the geometric constraints imposed by the manufacturer, through the utilization of the finite elements method. Finally, the power electronic circuitry was also designed. Numerical simulations of the components, as well as of the complete system, were performed and a prototype was built to widely verify the correspondence of the simulation outputs with the results obtained from an experimental measurements campaign.
Vent Distribution on Jeju Island, South Korea: Glimpses Into the Subvolcanic System

The spatial distribution of vents is ultimately controlled by the geometry of the magma source at depth, stress orientation and pre‐existing crustal structures. In this work, the spatial patterns of vent distribution in Jeju Island, South Korea, are examined through several methods. Comparison of the obtained distribution patterns with previous knowledge about the volcanic evolution of the island, and recent results of seismic tomographic images provides a comprehensive interpretation of vent distribution in terms of the underlying structure of the sub‐volcanic system. Thus, it is proposed that under certain conditions the probability density functions of some groups of vents can be used to obtain rough estimates of the depths of magma storage. Also, it is shown that the overall spatial pattern of vents provides an integrated image of the sub‐volcanic system both in space and time. The results reported in this work can therefore help us to avoid unjustified speculations concerning the nature of activity present in zones of distributed volcanism elsewhere.
Study on Air Pollution Behavior of VOCs with Photochemical Monitoring Stations Using EGARCH Model in Southern Taiwan

This study adopted the exponential generalized autoregressive conditional heteroscedasticity (EGARCH) model to examine the 10 ozone precursors of the highest concentrations among the 54 that were assessed over a number of years at the four photochemical assessment monitoring stations (PAMSs) in the Kaohsiung–Pingtung Area in Taiwan. First, the 10 ozone precursors, which were all volatile organic compounds (VOCs), were analyzed using the factor analyses in multiple statistical analyses that had the most significant impact on the area’s ozone formation: mobile pollution factor, which included 1,2,4-Trimethylbenzene (C9H12), toluene (C7H8), and Isopropyl benzene (C9H12). Then, taking into consideration that the number sequences might be affected by standardized residuals, this study applied the vector autoregressive moving average-EGARCH (VARMA-EGARCH) model to analyze the correlation between the three VOCs under different polluting activities. The VARMA-EGARCH model in this research included dummy variables representing changing points of variance structures in the variance formula to predict the conditional variance. This process proved able to effectively estimate the relevant coefficients of the three VOCs’ dynamic conditions that changed with time. The model also helped to prevent errors from occurring when estimating the conditional variance. Based on the testing results, this study determined the VARMA(2,1)-EGARCH(1,0) as the most suitable model for exploring the correlation between the three VOCs and meteorological phenomena, as well as the interplay between them in regard to interaction and formation. With the most representative of the three, toluene (TU), as the dependent variable and 1,2,4-Trimethylbenzene (TB) and Isopropyl benzene (IB) as the independent variables, this study found it impossible to calculate the TU concentration with TB and IB concentrations in the same period; estimations of TB and IB concentrations with a period of lag time were required because TU was mainly contributed by automobiles and motorcycles in Kaohsiung. TB and IB resulted from other stationary pollution sources in the region besides cars and motorbikes. When TU was evenly distributed and stayed longer in the atmosphere, the TB and IB concentrations were lower, so distribution conditions and concentrations could not be used to effectively estimate the concentration of toluene. This study had to wait until the next period, or when stationary pollution sources started producing TB and IB of higher concentrations during the daytime, in order to estimate the TU concentrations in a better photochemical situation.

Purpose: The aim of this study was to compare the effect of shock related to the COVID pandemic on the rates of return from shares of agri-food companies in Poland. Project/Methodology/Approach: In order to investigate the effect of the COVID pandemic on the capital market abnormal rates of return from shares were calculated as those rates of return, which may be considered the response of the market to the outbreak of the pandemic and its consequences. Results: Results of this analysis indicate a considerable drop in share prices and rates of return from shares of the WIG companies and agri-food companies following the detection of the first coronavirus case. In the analysed period the rates of return from shares of agri-food companies were higher than those from the WIG companies. Practical implications: This study indicates a research gap in this respect. The investigations have a huge effect on decisions of investors, enterprises from the agri-food sector and agribusiness. Results of this study will provide insight into the situation in the stock market during the pandemic, while they will also aid entities when making investment decisions and planning for the future. Originality/value: The novelty of this paper is connected with the contribution to science, since it is the first empirical study concerning the effect of the COVID-19 pandemic on the stock market in the agri-food sector of Poland.
Nutraceutical and Cosmeceutical Potential of Seaweed Derived Fucoxanthin

The marine ecosystem is considered a potentially mysterious reservoir of biodiversity consisting of a broad spectrum of bioactive constituents, whose potential is still under research for pharmaceuticals, nutraceuticals and cosmeceuticals. Fucoxanthin, a carotenoid, can be found in the brown seaweeds and is recognized to show promising and exclusive biological activities. Subsequent consumption and absorption of fucoxanthin leads to its accumulation in the white adipose tissue and helps to depict anti-obesity effects via upregulation of thermogenesis through uncoupling protein 1 expression and mitochondrial activation. Linking with anti-obesity, fucoxanthin shows antidiabetic potential by insulin resistance signalling pathways. Fucoxanthin is also reported to control carcinogenesis via regulating several biomolecules and signalling pathways which are intermittently linked with either apoptosis or cell cycle arrest or suppression of metastasis. In addition, it can act as a potential antioxidant by scavenging toxic free radicals and also aid in the treatment of neurodegenerative, hepatic and cardiovascular dysfunctions. Fucoxanthin has a profound role in the cosmetic industry for its mosquito repellent activity and protective effects on the blood vessels, skin and bones. Therefore, the current review provides the recent available scientific literature on Fucoxanthin regarding its health-promoting effects, modulating mechanism and future potential to use it as a commercially viable drug in nutraceutical and cosmeceutical applications.
Estimating the Importance of Hydrologic Conditions on Nutrient Retention and Plant Richness in a Wetlaculture Mesocosm Experiment in a Former Lake Erie Basin Swamp

The western basin of Lake Erie, the shallowest of the Laurentian Great Lakes in North America, is now plagued by harmful algal blooms annually due to nutrient discharges primarily from its basin. Water quality was impacted so significantly by toxic cyanobacteria in 2014 that the city of Toledo’s water supply was shut off, affecting hundreds of thousands of residents. A new agricultural land management approach, ‘wetlaculture (=wetland + agriculture)’, has a goal of reducing the need for fertilizer applications while preventing fluxes of nutrients to downstream aquatic ecosystems. A wetlaculture mesocosm experiment was set up on agricultural land near Defiance, Ohio, on the northwestern edge of the former ‘Great Black Swamp’. The mesocosms were randomly assigned to four hydrologic treatments involving two water depths (no standing water and ~10-cm of standing water) and two hydraulic loading rates (10 and 30 cm week−1). Nearby agricultural ditch water was pumped to provide weekly hydraulic loading rates to the mesocosms. During the two-year period, the net mass retention of phosphorus from the water was estimated to have averaged 1.0 g P m−2 in the wetland mesocosms with a higher hydraulic loading rate, while the highest estimated net nitrogen mass retention (average 22 g N m−2) was shown in the wetland mesocosms with 10 cm of standing water and higher hydraulic loading rate. Our finding suggests that hydrologic conditions, especially water level, contribute directly and indirectly to nutrient retention, partially through the quick response of the wetland vegetation community. This study provides valuable information for scaling up to restore significant areas of wetlaculture/wetlands in the former Great Black Swamp, strategically focused on reducing the nutrient loading to western Lake Erie from the Maumee River Basin.
Tissue expansion of ‘cleared’ whole brains reduces contrast in ex vivo MRI

Multimodal imaging of optically-cleared brains, ex vivo, by Magnetic Resonance Imaging (MRI) and light microscopy (LM) presents unique opportunities for studying the brain at various scales and resolutions. However, CLARITY -cleared brains lack MRI contrast, implicating lipids as the major source of MRI contrast. We explored the ex vivo MRI compatibility of uDISCO, ECi and Scale -cleared brains. Surprisingly, uDISCO and ECi -cleared brains retain MRI contrast, whereas Scale-cleared brains show a severe loss of MRI contrast, as CLARITY. Determination of lipid-content in cleared samples shows that CLARITY, uDISCO and ECi are strongly delipidating, whereas Scale preserves most lipids. We conclude that MRI contrast can be associated with tissue expansion (and hyperhydration) rather than with lipid-content. Thus, we present two clearing methods compatible with ex vivo MRI.

Dynamic Effective Elasticity of Melanoma Cells Under Shear and Elongational Flow Confirms Estimation From Force Spectroscopy

The detection and enrichment of circulating melanoma cells is a challenge as the cells are very heterogeneous in terms of their biomechanical properties and surface markers. In addition, there is a lack of valid and reliable biomarkers that predict progress and therapeutic response. We here analyzed the elasticity of A375 melanoma cells applying force spectroscopy and a microfluidic method. To identify and eventually separate circulating tumor cells, it is crucial to precisely know their physical properties. First, we used standard AFM force spectroscopy, where the elasticity of the cells is calculated from indentation with a pyramidal tip. To extend the limits of measurement with a tip, we then used cantilevers without a tip to press on the cells over a large area. The resulting Young’s moduli are slightly lower and vary less without tip presumably because of the inhomogeneity of the cells. Finally, we implemented our microfluidic method. We measured single cell elasticity by analyzing its deformation in high-speed micrographs while passing a stenosis. Combining the force field and the change in shape provides the basis for a stress strain diagram. The results from microfluidic deformation analysis were in accordance with the results from force spectroscopy. The microfluidic method provides advantages over conventional methods, since it is less invasive and less likely to harm the cell during the measurement, and the whole cell is measured as one entity without contact to a stiff substrate, while force spectroscopy is limited to the contact area of the tip, and in some cases dependent of the cell substrate interaction. Consequently, microfluidic deformation analysis allows to predict the overall elastic behavior of the whole inhomogeneous cell in three-dimensional force fields. This method may contribute to improve the detection of circulation melanoma cells in the clinical practice.
Literal translation: A study with several translation techniques to get a good translation result

In translating advertisements, there are things to keep in mind. First, ad text has a different type of character from other text, secondly, there are limitations in the ad itself. An advertisement is limited to customs and habits, religion and beliefs, norms and ethics as well as the use of language and language style. This implies that an advertisement cannot freely express the ideas or ideas of producers to potential consumers, especially if the advertisement is aimed at consumers who have different languages ​​and of course different cultures. A picture or sentence that can be considered neutral in one area but has a different interpretation in another. For example: in a print media commercial advertisement issued by the local government, one type of regional superior product is written which is called 'sarong goyor'. If this advertisement is given to an audience outside the area where the source text originates, then the word sarong goyor may become lepas in its meaning. For this reason, in translating a text, the translator needs to understand the approach, strategy and ideology used by the translator.
Evaluation of circulating IGF-I and IGFBP-3 as biomarkers for tumors in dogs

Background Serum-based parameters are considered non-invasive biomarkers for cancer detection. In human studies, insulin-like growth factor-I and II (IGF-I and IGF-II) and insulin-like growth factor binding protein-3 (IGFBP-3) are useful as diagnostic or prognostic markers and potential therapeutic targets. Objectives This study examined the diagnostic utility of circulating IGF-I, IGF-II, and IGFBP-3 levels in healthy dogs and dogs with tumors. Methods The serum concentrations of these biomarkers in 86 dogs with tumors were compared with those in 30 healthy dogs using an enzyme-linked immunosorbent assay (ELISA). Results The ELISA results showed no difference between healthy dogs and dogs with tumors in the serum IGF-II concentrations. On the other hand, there was a significant difference in the circulating IGF-I and IGFBP-3 levels between healthy dogs and dogs with tumors. The concentrations of serum IGF-I (median [interquartile range], 103.4 [59.5–175] ng/mL) in dogs with epithelial tumors were higher than those (58.4 ng/mL [43.5–79.9]) in healthy dogs. Thus, the concentrations of serum IGFBP-3 (43.4 ng/mL [33.2–57.2]) in dogs with malignant mesenchymal tumors were lower than those (60.8 ng/mL [47.6–70.5]) in healthy dogs. Conclusions The serum IGF-I and IGFBP-3 levels can be used as diagnostic biomarkers in dogs with tumors.
UAV Based Spatiotemporal Analysis of the 2019–2020 New South Wales Bushfires

Bushfires have been a key concern for countries such as Australia for a long time. These must be mitigated to eradicate the associated harmful effects on the climate and to have a sustainable and healthy environment for wildlife. The current study investigates the 2019–2020 bushfires in New South Wales (NSW) Australia. The bush fires are mapped using Geographical Information Systems (GIS) and remote sensing, the hotpots are monitored, and damage is assessed. Further, an Unmanned Aerial Vehicles (UAV)-based bushfire mitigation framework is presented where the bushfires can be mapped and monitored instantly using UAV swarms. For the GIS and remote sensing, datasets of the Australian Bureau of Meteorology and VIIRS fire data products are used, whereas the paths of UAVs are optimized using the Particle Swarm Optimization (PSO) algorithm. The mapping results of 2019–2020 NSW bushfires show that 50% of the national parks of NSW were impacted by the fires, resulting in damage to 2.5 million hectares of land. The fires are highly clustered towards the north and southeastern cities of NSW and its border region with Victoria. The hotspots are in the Deua, Kosciu Sako, Wollemi, and Yengo National Parks. The current study is the first step towards addressing a key issue of bushfire disasters, in the Australian context, that can be adopted by its Rural Fire Service (RFS), before the next fire season, to instantly map, assess, and subsequently mitigate the bushfire disasters. This will help move towards a smart and sustainable environment.
