Effect of Instruction with Visual Materials Based on Health Belief Model on Global Warming Perception Among University Students

Global warming is one of the most critical environmental problems of 21thcentury. It is not only environmental hazard but also social and economic risk and unfortunately some adverse consequences of it are becoming visible these days. Therefore, it is a great importance for educating people and making them aware of this problem. The study was aimed to examine the effect of instruction with visual materials based on health belief model on global warming perception among university students. Quasi experimental design with pre and post-test was utilized. This study was conducted at six faculties from both scientific and literary faculties in Shebin Elkom City at Menoufia University. Systematic random sample consisted of 360 university students including 144 males and 216 females aged between 18 to 22 years old who enrolled in the first academic years of both selected scientific and literary faculties in Shebin Elkom City. The following tools were used 1. Self-administered structured questionnaire which involved socio-demographic data and knowledge of university students about global warming. 2. Perception of students about global warming based on health belief model. The main result of this study showed that there was significant improvement in the knowledge and perception of university students' about global warming after instruction with visual materials compared to before instruction. Additionally, there was statistically significant relation between students' knowledge and perception toward global warming. The current study concluded that, instruction with visual materials was effective in improving knowledge and perception of university students about global warming. This result recommended that, the need for developing and establishing of environmental protection education programs to enhance environmental awareness of all students from elementary school to university level.
An Electrical and Polarimetric Analysis of the Overland Reintensification of Tropical Storm Erin (2007)

Abstract While passing over central Oklahoma on 18–19 August 2007, the remnants of Tropical Storm Erin unexpectedly reintensified and developed an eyelike feature that was clearly discernable in Weather Surveillance Radar-1988 Doppler (WSR-88D) imagery. During this brief reintensification period, Erin traversed a region of dense surface and remote sensing observation networks that provided abundant data of high spatial and temporal resolution. This study analyzes data from the polarimetric KOUN S-band radar, total lightning data from the Oklahoma Lightning Mapping Array, and ground-flash lightning data from the National Lightning Detection Network. Erin’s reintensification was atypical since it occurred well inland and was accompanied by stronger maximum sustained winds and gusts (25 and 37 m s−1, respectively) and lower minimum sea level pressure (1001.3 hPa) than while over water. Radar observations reveal several similarities to those documented in mature tropical cyclones over open water, including ou.
Condition dependence of testis size in small mammals

Sperm competition is a common phenomenon across the animal kingdom and is recognized as a major factor in the sexual selection of males. Intraspecific variation in testis size (ejaculate investment) has been implicated as an important factor in male reproductive success because larger testes produce higher quality ejaculates. Sexual selection theory predicts that traits associated with male–male competition or female mate choice must be costly and heritable to confer an evolutionary advantage to those individuals carrying such traits. Because ejaculate production can be costly, we tested the prediction that testis size is condition dependent using morphological data from three species of small mammals. In addition, subordinate males, which are less likely to copulate with a female at the optimal time for achieving fertilization, should invest more heavily in ejaculates than dominant males. Thus we also predicted that small males should invest more heavily in ejaculates than large males. In all three species, testis size was positively related to body condition (size-corrected body mass) and independent of body length. These results suggest that males in good condition are capable of investing more in ejaculates than males in poor condition, and are consistent with the costly nature of ejaculate production. In addition, the results are consistent with other traits that are condition dependent and that serve as honest signals of male quality, whether in the context of male–male competition or female mate choice.
Compare the Performance of Recovery Algorithms MP, OMP, L1-Norm in Compressive Sensing for Different Measurement and Sparse Spaces

In this paper, at first, compressive sensing theory involves introducing measurement matrices to dedicate the signal dimension and so sensing cost reduction, and sparse domain to examine the conditions for the possibility of signal recovering, are explained. In addition, three well known recovery algorithms called Matching Pursuit (MP), Orthogonal Matching Pursuit (OMP), and L1-Norm are briefly introduced. Then, the performance of three mentioned recovery algorithms are compared with respect to the mean square error (MSE) and the result images quality. For this purpose, Gaussian and Bernoulli as the measurement matrices are used, where Haar and Fourier as sparse domains are applied.
Relative Convergence in a Dual Economy with Tradeable and Non-Tradeable Goods

This paper develops a two-country two-sector endogenous growth model with a dual labour market based on efficiency wages. Growth is driven by Research done in the (high-tech) tradeable sector. The follower country tends to grow faster the greater the productivity gap from the leader country, but differences in unemployment benefit systems can lead to relative convergence, i.e. a steady state with the backward country lagging behind the leader country. The reason for this is that high social welfare benefits generate high unemployment and reduce the amount of labour employed for R&D purposes. Furthermore, it is shown that a shift in preferences towards non-tradeables can explain a global slowdown in economic growth.
Primary Teachers’ Perceptions on ICT Integration for Enhancing Teaching and Learning through the Implementation of One Laptop Per Child Program in Primary Schools of Rwanda

Identifying teachers’ perceptions for integrating ICT into teaching and learning processes through the implementation of One Laptop Per Child (OLPC) program in primary schools of Rwanda was the main target of this study. The study employed qualitative approach where thirty primary schools’ teachers participated into this study through interviews and group discussions designed for the research questions.

Through thematic analysis of data, the program was found to be influential to teachers, learners and stakeholders of primary schools in Rwanda. In order to be fruitful, the integration of ICT through implementation of OLPC program requires to help teachers to acquire skills related to Technological Pedagogical Content Knowledge (TPACK). The study also suggested different solutions and strategies related to all identified challenges.
Customer Perception towards Imported Cosmetics

The purpose of this research is to examine the factors influencing customer’s perception towards imported cosmetic goods, to find the role of trust & security in establishing favorable perception in the customer’s mind toward imported cosmetics and ultimately to know the customer’s perception and views about imported cosmetics.Multiple Regression and Correlation are used to test hypothesized relationships amongst the variables. The questionnaire is used to collect the data from a sample 150 respondents. The findings show that imported cosmetics have a positive influence on a customer's perception. We find that creating trust and feelings of security in customer’s minds can greatly facilitate the development of a positive and favorable perception towards imported cosmetics. These findings strengthen the customer's perception about brand consciousness and establish a baseline study for future research. Keywords : Customer perception, Trust, Ease of use and Security, imported cosmetics
ASSOCIATION FOR CONSUMER RESEARCH

We demonstrate that social crowdedness shapes creative thinking style. Specifically, individuals in crowded environments engage more in convergent thinking which worsens creative performance, while those in less crowded environments think more divergently which increases creative performance. This effect is moderated by crowd composition and is attenuated for in-group crowds. This research demonstrates that social crowdedness shapes creative performance. Specifically, socially crowded environments worsen creative performance due to the activated negative arousal. However, this effect is moderated by crowd composition and an individual’s need for arousal, and attenuated for sensation seekers and for crowds perceived positively.

GaAs quantum well (QW) lasers with distributed Bragg reflection (DBR) Al0.3Ga0. 7As/GaAs superlattice gratings have been fabricated by the single‐step, maskless focused ion beam (FIB) mixing. 200 keV Si++ FIB implantation with a beam diameter of ∼60–70 nm and a dose of 1014 cm−2 was used to obtain localized compositional mixing. The DBR grating period was 350 nm, corresponding to a third order grating matched to the emission from the 30 nm wide QW. Lasing operation was examined by optical pumping. With a pumping power 1.6× the threshold value, lasing modes were observed near 827 nm, with a spacing of 3 A and a linewidth of 1.5 A.
Chaos, Solitons and Fractals

Multiple strains of the SARS-CoV-2 have arisen and jointly inﬂuence the trajectory of the coronavirus disease (COVID-19) pandemic. However, current models rarely account for this multi-strain dynamics and their different transmission rate and response to vaccines. We propose a new mathematical model that accounts for two virus variants and the deployment of a vaccination program. To demonstrate utility, we applied the model to determine the control reproduction number ( R c ) and the per day infection, death and recovery rates of each strain in the US pandemic. The model dynamics predicted the rise of the alpha variant and shed light on potential impact of the delta variant in 2021. We obtained the minimum percentage of fully vaccinated individuals to reduce the spread of the variants in combination with other intervention strategies to deaccelerate the rise of a multi-strain pandemic. © 2022 Elsevier Ltd.

Equivariant Modular Categories via Dijkgraaf-Witten Theory

Based on a weak action of a nite group J on a nite group G, we present a geometric construction of J-equivariant Dijkgraaf-Witten theory as an extended topological eld theory. The construction yields an explicitly accessible class of equivariant modular tensor categories. For the action of a group J on a group G, the category is described as the representation category of a J-ribbon algebra that generalizes the Drinfel’d double of the nite group G.
Knowledge management in the rugby team: a factor of Englandâ€™s 2003 rugby world cup success

This paper aims to present how knowledge can be managed in a sport team, by using the example of the English national rugby team, which won the World Cup in 2003, under the management/coaching of Clive Woodward. The paper is based on the idea that knowledge management is a key driver of sporting success. The first part of the research presents a theoretical approach both on knowledge management in sport and on obtaining success in rugby. Then, there follows a presentation about how knowledge was created at the English rugby team, and how it helped in winning the World Cup. An important role is played by the manager, who is seen as the initiator of knowledge in the team. Few research has been done on knowledge management in sport, and in order to be as explicit as possible, the paper tries to combine the theory â€“ built on ideas of experimented writers, such as Nonaka â€“ with the practice observed at the English national rugby team between 1997 and 2003.
Cover-Crop Roller–Crimper Contributes to Weed Management in No-Till Soybean

Abstract Termination of cover crops prior to no-till planting of soybean is typically accomplished with burndown herbicides. Recent advances in cover-crop roller–crimper design offer the possibility of reliable physical termination of cover crops without tillage. A field study within a no-till soybean production system was conducted in Urbana, IL, from 2004 through 2007 to quantify the effects of cover crop (cereal rye, hairy vetch, or bare soil control), termination method (chemical burndown or roller–crimper), and postemergence glyphosate application rate (0, 1.1, or 2.2 kg ae ha−1) on soybean yield components, weed–crop interference, and soil environmental variables. Biomass of weeds surviving management within a soybean crop following either a vetch or rye cover crop was reduced by 26 and 56%, respectively, in the rolled system compared to the burndown system. Soybean yield loss due to weed interference was unaffected by cover-crop termination method in soybean following a rye cover crop, but was higher in the rolled than burndown treatment in both hairy vetch and bare soil treatments. In soybean following a rye cover crop, regardless of termination method, yield loss to weed interference was unaffected by glyphosate rate, whereas in soybean following a vetch cover crop or bare soil, yield loss decreased with glyphosate rate. Variation in soybean yield among cover crops and cover-crop termination treatments was due largely to differences in soybean establishment, rather than differences in the soil environment. Use of a roller–crimper to terminate a cover crop preceding no-till soybean has the potential to achieve similar yields to those obtained in a chemically terminated cover crop while reducing residual weed biomass.

Threshold of carbonate saturation state determined by CO 2 control experiment

Abstract. Acidification of the oceans by increasing anthropogenic CO2 emissions will cause a decrease in biogenic calcification and an increase in carbonate dissolution. Previous studies have suggested that carbonate dissolution will occur in polar regions and in the deep sea where saturation state with respect to carbonate minerals (Ω) will be 1. This is probably related to the dissolution of reef carbonate (Mg-calcite), which is more soluble than aragonite. However, the threshold of Ω for the dissolution of natural sediments has not been clearly determined. We designed an experimental dissolution system with conditions mimicking those of a natural coral reef, and measured the dissolution rates of aragonite in corals, and of Mg-calcite excreted by other marine organisms, under conditions of Ωa > 1, with controlled seawater pCO2. The experimental data show that dissolution of bulk carbonate sediments sampled from a coral reef occurs at Ωa values of 3.7 to 3.8. Mg-calcite derived from foraminifera and coralline algae dissolves at Ωa values between 3.0 and 3.2, and coralline aragonite starts to dissolve when Ωa = 1.0. We show that nocturnal carbonate dissolution of coral reefs occurs mainly by the dissolution of foraminiferans and coralline algae in reef sediments.
Selection of halophilic bacteria for biological control of tomato gray mould caused by Botrytis cinerea

In Morocco, tomato gray mould caused by Botrytis cinerea Pers: Fr. is a serious threat for postharvest storage of tomatoes. Fifteen halophilic bacteria were evaluated for their antagonistic activity against B. cinerea : 11 Gram positive strains assigned to the genera Bacillus (9), Jeotgalibacillus (1) and Planococcus (1) and four Gram negative strains assigned to the genera Salinivibrio (1), Vibrio (2) and Photobacterium (1). In in vitro screening, 12 antifungal isolates secreted diffusible compounds, hydrolytic enzymes or volatile compounds. In vivo screening of the isolates, Bacillus safensis CCMM B582 and Bacillus oceanisediminis CCMM B584 showed permanent antagonistic activity on tomato fruits, with 100% inhibition of B. cinerea after 7 days. These two strains may offer potential for biological control of tomato gray mould.
MOVING OBJECT AWARE VIDEO COMPRESSION

Moving object is detected by simple spatial and temporal gradients in GOP (Group of Frame) of H.264/AVC such that the MOOI (Moving-Object-of-Interest) is remained as much as possible while the non-MOOI is squeezed. This resizing process to original video is applied as a pre-processing for standard video compression. Specifically, more image data of the original video will be dropped by our non-uniform subsampling as the distance from the center of the MOOI increases. Experimental results show that our MOOI aware video compression can preserve the original visual quality of the MOOI even for low bit-rate applications.

The Effect of Linseed Consumption on Blood Pressure and Laboratory Parameters in Healthy Adults who Exercise Regularly

Objective: This study was designed to investigate the impact of linseed consumption on blood pressure and laboratory tests in healthy individuals who do and do not exercise regularly. Material and Method : This study included 15 male subjects and 15 female subjects between 25 and 45 years of age without any clinical complaints and manifestations, who have been exercising regularly for at least a year. Age-matched individuals who had not been exercising regularly were included as the control group. Subjects orally received 20 grams of freshly ground linseed daily on an empty stomach in the morning, 30 minutes before the breakfast for 12 weeks. Blood samples were drawn into biochemistry and hemogram tubes at the start and end of the trial. The following parameters were investigated on these samples: glucose, urea, creatine, cholesterol, triglyceride, high density lipoprotein (HDL), aspartate aminotransferase (AST), alanine aminotranferase (ALT), Gamma-glutamyl transpeptidase (GGT) , Alkaline phosphatase (ALP), creatine kinase (CK), creatine kinase MB (CK-MB), lactate dehydrogenase (LDH), uric acid, calcium (Ca), iron (Fe) and haemogram. The cases w ere also monitored for blood pressure and body weight. Results : Changes in ALP, CK, Ca, Fe, red blood cell (RBC) and weight were significant of males who did not exercise (p<0.05, p<0.01). The males who exercised regularly exhibited significant changes in urea, cholesterol, triglyceride, HDL, AST, ALT, LDH, Fe, haemoglobin (HGB), haematocrit (HCT), mean corpuscular hemoglobin concentration (MCHC), platelet distrubition width (PDV) and weight (p<0.05, p<0.01). Females who did not exercise had significant changes in glucose, HDL, ALP, CK, CK-MB and uric acid, RBC and HCT (p<0.01). Females who exercised regularly exhibited significant changes in glucose, cholesterol, triglyceride, HDL, AST, ALP, CK, LDH, Ca, Fe, RBC, HGB, lymphocyte (LYM) and diastolic blood pressure (p<0.05, p<0.01). Conclusion : Regular exercise and linseed consumption have a favorable impact on the lipid metabolism and regulate blood pressure. The absence of elevations in the hepatic and renal enzymes suggests that linseed is not toxic for the organism. The fact that some of the biochemical and hematologic parameters are in line with data reported in the literature while some exhibit differences relative to the data underlines the necessity of supporting these results on exercise combined with linseed consumption with future trials.
Piezoresistivity and Mechanical Behavior of Metal-polymer Composites under Uniaxial Pressure

The piezoresistive response of copper and nickel particles reinforced polydimethylsiloxane (PDMS) polymer, forming metal-polymer composites were investigated under uniaxial pressure. Electrical and mechanical properties of composite samples containing Cu and Ni conductive fillers at different loadings in polydimethylsiloxane (PDMS) polymer matrix have been presented here. Well-dispersed metal-polymer composites were fabricated by a wet mixing route. The resulting Cu-PDMS and Ni-PDMS composite samples show the resistivity changes by more than 2 and 10 orders of magnitude around 4MPa pressure, respectively. The mechanical tests have shown that these composite samples have high stress sensitivity which makes them good piezoresistive candidates for practical applications.
Computational design of high performance hybrid perovskite on silicon tandem solar cells

In this study, the optoelectronic properties of a monolithically integrated series-connected tandem solar cell are simulated. Following the large success of hybrid organic-inorganic perovskites, which have recently demonstrated large efficiencies with low production costs, we examine the possibility of using the same perovskites as absorbers in a tandem solar cell. The cell consists in a methylammonium mixed bromide-iodide lead perovskite, CH3NH3PbI3(1-x)Br3x (0 \textless x \textless 1), top sub-cell and a single-crystalline silicon bottom sub-cell. A Si-based tunnel junction connects the two sub-cells. Numerical simulations are based on a one-dimensional numerical drift-diffusion model. It is shown that a top cell absorbing material with 20% of bromide and a thickness in the 300-400 nm range affords current matching with the silicon bottom cell. Good interconnection between single cells is ensured by standard n and p doping of the silicon at 5.10^19cm-3 in the tunnel junction. A maximum efficiency of 27% is predicted for the tandem cell, exceeding the efficiencies of stand-alone silicon (17.3%) and perovskite cells (17.9%) taken for our simulations, and more importantly, that of the record crystalline Si cells
