Exploration of Physical Education Teaching Design and Student Ability and Character Cultivation Based on Positive Psychological Influence

Physical education is an educational process that cultivates people. In happy, lively, and rich physical education classroom, students can achieve significant development in moral character, intelligence, physical fitness, skills, interpersonal communication, and other aspects. Design of physical education curriculum teaching based on positive psychological influence applies positive psychological influence in the process of physical education teaching and constructs a correlation model between teaching content of physical education curriculum and the cultivation of students' quality, ability, and personality quality. Embed positive psychological influencing factors into the content of the physical education teaching section, use scientific process control theory for sports training to monitor and personalize student health data (optimal heart rate), and design innovative physical education curriculum teaching plans. Organic integration of physical education teaching content with the cultivation of students' abilities and personality qualities, followed by the design, process organization, and implementation of physical education teaching, is an innovative path for the future development of physical education teaching.
Aqueous Extract of Onion Peels as A Biowaste-Based Sensitizer for Photovoltaic Cells

In the present paper, two natural photosensitizers extracted from red onion peels have been experimentally studied to sensitize the photovoltaic cells. The two natural dyes were prepared overnight, soaking the red onion peel powder in distilled water without acidification (UW) and acidified water (AW). Dye characteristics were identified by UV-vis Spectrophotometer and FT-IR Spectrophotometer. The cell performance was assessed by calculating the produced voltage and current by multi-meter. Red onion peel dyes absorb visible light at a wavelength of 507 nm and promote electron transfer into the porous semiconductor surface. A higher power conversion efficiency (η=0.0535 %) was featured by an unacidified solvent with a short circuit current density (Jsc) of 0.96 mA.cm-2, an open circuit voltage (Voc) of 338 mV and a fill factor of 0.2576. This paper presents a fascinating preliminary study to develop renewable and sustainable energy sources using bulky biowaste.
Influence of snow cover duration on soil evaporation and respiration efflux in mixed‐conifer ecosystems

Subalpine mixed‐conifer ecosystems are dependent on snowfall, which is expected to decrease under projected climate change. Changes in snowpack are likely to have important consequences for water and carbon cycling in these and downstream ecosystems. Particularly within semi‐arid environments, snowpack changes will directly influence localized water and carbon dynamics and indirectly influence regional‐scale levels of water availability and carbon sequestration. In this study, we monitor soil evaporation (E) and soil respiration (R) and evaluate how snow cover affects these effluxes within a mixed‐conifer ecosystem within the Santa Catalina Mountains about 10 km north of Tucson, Arizona. Using time‐lapse digital photos, we identified areas of consistent short and long snow duration, and we monitored E and R in these areas every 2 weeks for 15 months. Our primary findings include the following: (1) Dynamics of E are not different between long and short snow season sites, (2) E for both short and long snow seasons has a strong relationship with soil moisture and a poor relationship with soil temperature, (3) dynamics of R vary between long and short snow season sites throughout the year, with short snow season fluxes typically higher than those of long snow season sites, and (4) R for short and long snow seasons has a strong relationship with soil temperature and a poor relationship with soil moisture. Because climate change will only exacerbate both drying–wetting and cooling–warming cycles, detangling these complex relationships becomes increasingly important for understanding shifts in carbon dynamics in these subalpine mixed‐conifer ecosystems.

Inversion of the HF radar Doppler spectrum for ocean wave measurement

An unambiguous measurement of the directional spectrum is obtained. The estimates are amplitudes on a nonuniform 2-D wavenumber grid with a short-wave cut-off (due to a requirement to linearise the integral equation) which is at 0.2 Hz at 7MHz (a radar frequency which provides a long-range measuring capability) and 0.3Hz at 27 MHz. There is a long wave cut-off which varies with spectral quality and ocean conditions but which is at about 0.05 Hz. Beyond the short wave cut-off the spectral estimates are those of the initialisation.
Downstream signalling of the disease‐associated mutations on GPR56/ADGRG1

GPR56/ADGRG1 is an adhesion G protein‐coupled receptor (GPCR) and mutations on this receptor cause cortical malformation due to the over‐migration of neural progenitor cells on brain surface. At pial surface, GPR56 interacts with collagen III, induces Rho‐dependent activation through Gα12/13 and inhibits the neuronal migration. In human glioma cells, GPR56 inhibits cell migration through Gαq/11‐dependent Rho pathway. GPR56‐tetraspanin complex is known to couple Gαq/11. GPR56 is an aGPCR that couples with various G proteins and signals through different downstream pathways. In this study, bilateral frontoparietal polymicrogyria (BFPP) mutants disrupting GPR56 function but remaining to be expressed on plasma membrane were used to study receptor signalling through Gα12, Gα13 and Gα11 with BRET biosensors. GPR56 showed coupling with all three G proteins and activated heterotrimeric G protein signalling upon stimulation with Stachel peptide. However, BFPP mutants showed different signalling defects for each G protein indicative of distinct activation and signalling properties of GPR56 for Gα12, Gα13 or Gα11. β‐arrestin recruitment was also investigated following the activation of GPR56 with Stachel peptide using BRET biosensors. N‐terminally truncated GPR56 showed enhanced β‐arrestin recruitment; however, neither wild‐type receptor nor BFPP mutants gave any measurable recruitment upon Stachel stimulation, pointing different activation mechanisms for β‐arrestin involvement.
Infiltratie en herverdeling van water in grond

The flow of the liquid phase trough a soil can be predicted from pressure gradients. Different ways of predicting infiltration for irrigation of a basin were compared: numerical approximation; semianalytical; and analytical. A partly emperical equation was developed for description of rate of infiltration, after examination of existing equations. Under certain condions, infiltration was influenced by under or over pressure of the trapped gas phase and by swelling of clays. Complex models for redistribution were of little value in practice, since they could not be generalized and required too much physical data about the soil. A scheme was developed that grouped techniques for estimating physical properties of soil, according to cost and expertise required.
Experimental study of Ni adsorption on chalk: preliminary results

Abstract Nickel can cause allergic reactions so it is often considered to be a toxic metal. In some areas of Denmark and northern Europe, where drinking water comes predominantly from chalk aquifers, Ni concentrations in groundwater are higher than safety limits. The contamination is natural in the sense that it comes from oxidation of small grains of pyrite in the chalk that contain Ni as a trace element (Larsen and Postma, 1997). Because of Danish water-treatment practice, the most politically acceptable water-supply protocol is not to use secondary water treatment, so in order to minimize allergy risks for consumers, high-Ni water is either mixed with low-Ni water to bring concentrations below the Danish limit, or new, uncontaminated wells are drilled. Some recent efforts focused on finding a method to minimize nickel concentration while the water is still in the ground, before it is pumped to the primary treatment facility and distributed. Unfortunately, only a few experimental studies of the interactions between Ni and calcite have been published (Lakshtanov and Stipp, 2007; Zachara et al., 1991; Hoffmann and Stipp, 2001) and we found no previous work on Ni uptake by chalk. Experiments with calcite show that Ni forms surface complexes and it is incorporated into the solid as solid solution. Chalk aquifers often contain as much as 99% calcite, so the same processes ought to control Ni uptake, but some very preliminary experiments suggested that chalk behaviour might not be what one would expect by analogy with calcite (Stipp et al., 2005). The aim of this study was to examine the Ni-uptake capacity of chalk and compare it with that of synthetic, pure calcite.

Further, the research investigates the direct and indirect association among the study variables. The preliminary analysis discloses that the means of all the study variables. It was found that the Perceived financial service Quality and Marketing mix strategy has a significant positive association with Value in behavior. Further, Perceived Financial service quality has a positive significant association with customer satisfaction and customer loyalty in the Arab bank in Jordan. Additionally, Perceived financial service orientation has a positive significant relationship with customer satisfaction and customer loyalty. Further, a Marketing mix strategy has a positive significant relationship with customer satisfaction and customer loyalty. At last, customer satisfaction and customer loyalty have a positive significant relationship with Value in behavior. Further, it was found that perceived financial service orientation has a negative significant relationship with Value in behavior. Besides, Customer satisfaction and Customer loyalty partially mediate the relationship between Perceived financial service quality and Value in behavior. Likewise, Customer satisfaction and customer loyalty cannot mediate the relationship between Perceived financial service orientation and Value in behavior because hypothesis is rejected. Therefore. Finally, Customer satisfaction and Customer loyalty partially mediate the relationship between Marketing mix strategy and Value in behavior were partially supported.

On the effect of the volcanic eruptions of Mount Agung and El Chichón on the temperature of the stratosphere

During the summer and autumn of 1982, and also during the summer and autumn of 1963, the 30 mbar temperature rose more than three standard deviations above the 18 years average over tropical latitudes. These warmings are attributed to the stratospheric aerosols produced by the eruptions of Mount Agung in March 1963 and El Chichon in April 1982.
DEVELOPMENT, FORMULATION, AND EVALUATION OF ALOE VERA TOOTH GEL: AN ANTIMICROBIAL STUDY

Objective: The purpose of the current study was to develop and formulate tooth gel using Aloe vera leaf extract and evaluate. The experiment was designed to provide scientific proof of the antimicrobial activity of Aloe vera (Aloe barbadensis Mill) in tooth gel formulation against bacteria Staphylococcus aureus which causes infections associated with dental caries. Methods: Transparent Aloe vera gel extract was consistently blended for five minutes at 1000 Rotations Per Minute (RPM). Carbopol 940 and Carboxy Methyl Cellulose (CMC) were used as excipients in the formulation of Aloe vera tooth gel. Results: The formulated Aloe vera tooth gel was evaluated by physical examination such as color (yellowish green), good homogeneity and smoothness. pH and viscosity of developed tooth gel preparation were found to be 7.9 and 4.9 Pa. S respectively. The developed Aloe vera tooth gel showed considerable effectiveness with a Zone of Inhibition (ZOI) of 0.022 m, according to an antimicrobial study against Staphylococcus aureus. A comparison between formulated gel and marketed products (Colgate Natural Extract Aloe vera, Himalaya Herbal Active Fresh, Dabur Red) was also carried out. Conclusion: The formulated herbal tooth gel exhibited antimicrobial activity against gram-positive bacteria Staphylococcus aureus. The developed formulation (F4) with the ZOI of 0.022 m could be comparable with the marketed product.
Heparin Precursors with Reduced Anticoagulant Properties Retain Antiviral and Protective Effects That Potentiate the Efficacy of Sofosbuvir against Zika Virus Infection in Human Neural Progenitor Cells

Zika virus (ZIKV) infection during pregnancy can result in severe birth defects, such as microcephaly, as well as a range of other related health complications. Heparin, a clinical-grade anticoagulant, is shown to protect neural progenitor cells from death following ZIKV infection. Although heparin can be safely used during pregnancy, it retains off-target anticoagulant effects if directly employed against ZIKV infection. In this study, we investigated the effects of chemically modified heparin derivatives with reduced anticoagulant activities. These derivatives were used as experimental probes to explore the structure–activity relationships. Precursor fractions of porcine heparin, obtained during the manufacture of conventional pharmaceutical heparin with decreased anticoagulant activities, were also explored. Interestingly, these modified heparin derivatives and precursor fractions not only prevented cell death but also inhibited the ZIKV replication of infected neural progenitor cells grown as neurospheres. These effects were observed regardless of the specific sulfation position or overall charge. Furthermore, the combination of heparin with Sofosbuvir, an antiviral licensed for the treatment of hepatitis C (HCV) that also belongs to the same Flaviviridae family as ZIKV, showed a synergistic effect. This suggested that a combination therapy approach involving heparin precursors and Sofosbuvir could be a potential strategy for the prevention or treatment of ZIKV infections.
Thinking about the Future of Global Water Governance

Global water problems are likely to increase in severity, rendering existing governance approaches unable to cope with the resulting problems. We inquire into the relationship between global water governance structures, particularly those involving the United Nations, and look at how those structures are likely to respond to and shape projected water futures. Building on story lines of possible water futures taken from existing scenarios, we discuss the functions to be performed by global water governance. We aim to open a discussion about four global water governance options and to introduce the constraints and possibilities for each option. We argue that the nature of the water problem calls for structural changes. However unfeasible these may appear today, such transitions do occur, and, if the narrative is sufficiently sound, it can be used by social movements and networks to mobilize policy entrepreneurs and directional leaders to work for such changes.
Measuring social media impact on Impulse Buying Behavior

Abstract In today’s ever-evolving business landscape, understanding the shifting buying behaviors of consumers has become a formidable challenge for businesses worldwide. To navigate these changes successfully, businesses are increasingly turning to Social Networking Sites (SNS) to attract, connect with, and engage customers profitably. However, analyzing the influence of social networking sites on Impulse Buying Behavior (IBB) among customers is challenging for businesses and significant for their sustainability in the market. The main purpose of the present research work is to analyze the influence of social media on Impulse Buying Behavior (IBB) among customers in Saudi Arabia. The present quantitative study was conducted by sending a survey questionnaire to 342 Saudi Arabian consumers who are also users of social media. Data analysis was done using the PLS-SEM technique using smart PLS 4.0 software. The findings of the study suggested that Social Media Advertising (SMA) significantly influenced Impulse Buying Intention (IBI), but no effect was reported by the Social Media Community (SMC) on Impulse Buying Intention (IBI). However, the overall model explained 50 percent Impulse Buying Intention (IBI) and 33 percent Impulse Buying Behavior (IBB). The study will enable marketers, scholars, and researchers to understand the concept of Impulse buying by offering managerial implications and future research directions.
Salt Crystallization on Crazannes Limestone in a Long-Term Storage Environment

This study focuses on the damage caused by salt crystallization and the associated weathering processes in Crazannes limestone during storage. The main objective was to understand the factors contributing to the limestone’s observed flaking and granular disintegration, which cannot be attributed to frequent salt crystallization cycles experienced in outdoor exposure. Porosity and chemical analyses were performed to identify the salt minerals and their distribution within the stone’s microstructure. Chemical analyses revealed the presence of gypsum on the powdery weathered residues and stone surface, while halite was consistently found throughout the samples, with higher concentrations on the surface. The storage of the blocks in a closed room led to moisture evaporation and an increase in relative humidity (RH) ranging from 60% to 75%. Under these conditions, the gypsum crust remained relatively stable. The threshold for halite crystallization decreased to 65% RH in the presence of other salts. Consequently, even slight fluctuations in RH (%) caused by seasonal variations could induce cycles of NaCl crystallization and dissolution, resulting in damage behind the gypsum crust that protects the surface. Despite gypsum and halite not being the most aggressive salts, the porous nature of Crazannes limestone made it highly susceptible to salt-induced deterioration, leading to significant damage during storage, even with a minimal number of cycles. These results highlight the importance of controlling the storage conditions when stones are contaminated by salts.
Temporal and Spatial Analysis of Rainfall and Evapotranspiration in Erbil Plain and the Peripheral Areas

Since analysis of spatial events is region specific and cannot be generalized, local studies are of vital importance to identify the most accurate interpolation methods. Furthermore, the trend analysis of climatic parameters at different time scales is helpful for making a better climate change adaptation and mitigation plan to overcome water scarcity. Accordingly, the current study was proposed to detect trends in rainfall and evapotranspiration at monthly and annual time scales over the Erbil plain and the surrounding area using parametric and non-parametric tests. Moreover, four deterministic and five geostatistical methods were evaluated for searching the best interpolation method to generate a continuous surface for the indicated climatic variables. The results revealed that the majority of data sets are categorized useful class and serially independent. Furthermore, it was found both rainfall and potential evapotranspiration have a mix of upward and downward trends and most of them are insignificant at 5% level of significance. Further, the interpolation analysis indicated that local polynomial interpolation (LPI) method was proven to be best interpolator for generating continuous surfaces for rainfall and ETo over the area under study followed by the empirical Bayesian Kriging method.
