    Lying cues observed by men and women were investigated by a combination of a 2x2 mixed subjects design and a correlational design. Fifty-nine male and 68 female fluent English-speaking college students older than 18 years of age were tasked with completing a 64-item questionnaire and observing two video clips. The participants completed the questionnaire for a self-assessment of the perception of their own lying cues, observed the video clips, and then completed the questionnaire for an assessment of the lying cues observed in the videos. Independent sample t-test results indicated that, for self-assessment of lying cues, there was a statistically significant difference in the speech behavior and facial behavior lying cues of men and women. Pearson correlation indicated that there was a correlation between the lying cues and gender. Results are discussed in terms of self-other theory and gender differences in nonverbal behavior

    In this paper, screening study in regards to preparation of functionalized multi-walled carbon nanotubes (FMWNT)-supported bi-metallic catalyst is discussed. Functional groups such as hydroxyl and carboxylic acid are introduced on multi-walled carbon nanotubes (MWCNT) surface using acid treatment method with the aid of probe-type ultrasonication. It is done by varying the concentration of nitric acid (HNO3) and sulphuric acid (H2SO4), acid volume ratio and treatment duration. Catalysts with different ratios of cerium and nickel nanoparticles which are either loaded inside or outside of MWCNT were prepared via ultrasonic-assisted co-precipitation method (NiCe/CNT). This is done to study the effect of cerium loadings. The characterization of the FMWNT and catalysts are carried out using transmission electron micrographs (TEM), Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), and Raman spectroscopy. The results showed that the treatment in concentrated HNO3/H2SO4 with volume ratio of 3:1 for 8 h was the most suitable condition to generate large amount of surface oxygen group with minimal defects. The observations for each used condition were discussed thoroughly. Decoration of MWCNT with different metal loadings resulted in different distribution and dispersion of metal on nanotubes surface

    Today, tourism as a global and social phenomenon has special implication of its own. The mechanism behind the phenomenon intertwines and takes different forms in different times and places and completely different effects on the human beings (de freitas, 2003:47). There are many types of tourism. One of the most important tourism forms is religious tourism. Religious tourism is a combination of travel and religion. Most writers are taking into account religious tourism as a part of cultural tourism. Of course, both are quite different, but these two are tied together, and religion is a part of culture. Religious Cultural Festival is an event that causes tourism to travel to a foreign country for looking for religion and heritage experience. Hence the Muharram ceremonies (Ashura and Tasua) as a religious event can be raised as an event that can familiarize domestic and foreign tourists with part of Iranian religious and culture society. Iran is an old and historical country and its present religious is Islam, most of the people are Shia? The ceremonies of Tasua and Ashura in most part of this country with different showings are done. One of those is in Taft city located in Yazd province. This research is with aims to optimize utilization of the Ashura and Tasua religious festival in order to develop Taft city and to remove barriers on the way of Taft religious tourism using the SWOT model. This evaluation model (that evaluated strengths, weaknesses, opportunities and threats) is considered one of the best strategies for tourism planning. Methods of data collection and analysis of required data is more documentaries, analytical and Survey research. The results indicate that proximity to population centers and urban centers, such as the city of Yazd and distinctive funeral\u27s style from other parts of Province, are the best strengths for this city\u27s religious tourism. Short duration of tourists stay in the cities and Lack of tourists\u27 economic outputs in the city are the weaknesses. Finally, considering to strengths, weaknesses, threats and opportunities were presented competitive - aggressive, variation, revision and defensive strategies

    <p class="abstract"><strong>BACKGROUND:</strong> In view of the growing trend of obesity around the world, including in our country, and the effect of reduced physical activity in increasing the incidence of obesity and overweight in children and adolescents and limitations of families in providing transport for their children to attend exercise classes, as well as time limitations of students in taking part in these classes, accessing appropriate methods for presenting physical activity training seems essential.</p> <p class="abstract"><strong>&nbsp;&nbsp; METHODS:</strong><strong> </strong>This non-pharmacological clinical trial was performed during six months from May to November 2007 on 105 children and adolescents aged 6-18 years with obesity, randomly assigned to 3 groups of thirty-five. Nutrition and treatment behavior were the same in all groups, but physical activity training in the first group was taking part in physical activity training classes twice a week, in the second group by providing a training CD, and in the third group via face-to-face training. Before and after the intervention, anthropometric indicators were measured and recorded.</p> <p class="abstract"><strong>&nbsp;&nbsp; RESULTS:</strong> Mean body mass index (BMI) of participants in group attended physical activity training classes, and in the group undergone training with CD, after the interventions was significantly lower than that before the intervention.<strong>&nbsp;</strong></p> <p class="abstract"><strong>&nbsp;&nbsp; </strong><strong>CONCLUSION:</strong> Our findings demonstrated that training using CDs can also be effective in reducing BMI in overweight and obese children and adolescents as much as face-to-face education and participation in physical training classes. Extending such interventions can be effective at the community level.</p> <p class="abstract">&nbsp;</p><table cellspacing="0" cellpadding="0" align="left"><tbody><tr><td width="35" height="12"><br /></td></tr> <tr><td><br /></td> <td>&nbsp;</td></tr></tbody></table><p class="abstract">&nbsp;</p> <strong>Keywords:</strong> Children, adolescents, physical activity, education, obesity, treatment

    The use of remote sensing is particularly important in identifying burned areas due to its extensive spatial coverage and the provision of information at different times. Today, Modis fire products are widely used for this purpose. The purpose of this study is to evaluate the capability of Modis MOD14, MOD14A2 (Terra), and MYD14, MYD14A2 (Aqua) fire detector products and to identify fire areas in Golestan state. First, a point map of all the images was generated, then to evaluate the accuracy of the fire products, the prepared point map for the products was compared with terrestrial reality data. If the location of each of the reported fires is consistent with the fires identified by the products, that location was correctly identified as the fire. Landsat images were used as a ground accuracy map to evaluate the accuracy of Modis images. The results showed that six regions identified by level 2 fire products and eight regions were detected by level 3 fire products were identified. The results show the accuracy of the images with a coefficient of R ^ 2 of 0.94 and a coefficient of RMSE of 426.12 ha. The studies conducted in this study show that to improve the performance of the text fire detection algorithm, this algorithm is proposed for the forests of Golestan province and following the conditions and characteristics of the fire area, its intensity, and area. Be developed to provide better results

    Contributions of Smart City Solutions and Technologies to Resilience against the COVID-19 Pandemic: A Literature Review

    Get PDF
    Since its emergence in late 2019, the COVID-19 pandemic has swept through many cities around the world, claiming millions of lives and causing major socio-economic impacts. The pandemic occurred at an important historical juncture when smart solutions and technologies have become ubiquitous in many cities. Against this background, in this review, we examine how smart city solutions and technologies have contributed to resilience by enhancing planning, absorption, recovery, and adaptation abilities. For this purpose, we reviewed 147 studies that have discussed issues related to the use of smart solutions and technologies during the pandemic. The results were synthesized under four themes, namely, planning and preparation, absorption, recovery, and adaptation. This review shows that investment in smart city initiatives can enhance the planning and preparation ability. In addition, the adoption of smart solutions and technologies can, among other things, enhance the capacity of cities to predict pandemic patterns, facilitate an integrated and timely response, minimize or postpone transmission of the virus, provide support to overstretched sectors, minimize supply chain disruption, ensure continuity of basic services, and offer solutions for optimizing city operations. These are promising results that demonstrate the utility of smart solutions for enhancing resilience. However, it should be noted that realizing this potential hinges on careful attention to important issues and challenges related to privacy and security, access to open-source data, technological affordance, legal barriers, technological feasibility, and citizen engagement. Despite this, this review shows that further development of smart city initiatives can provide unprecedented opportunities for enhancing resilience to the pandemic and similar future events

    Effect of reaction time and catalyst feed rate towards carbon nanotubes yields and purity by using rotary reactor

    Continuous production of multi-walled carbon nanotubes (MWCNTs) by chemical vapor deposition (CVD) method was investigated in a rotary reactor. The aim of the study was to investigate the effect of catalyst feeding rate and reaction time on the MWCNTs production yield and purity. Bimetallic Co-Mo supported on MgO was used for the growth of MWCNTs and methane gas was used as the carbon precursor. The results indicated that the highest yield of MWCNTs production was attained at the reaction time of 180 min and catalyst feeding rate of 100 mg/min; this sample also had the highest purity (99.16%). SEM and TEM analyses of the synthesized product confirmed that most of the MWCNTs were sinuous and entangled with a uniform diameter. Raman spectroscopy indicated that the as-produced MWCNTs were mostly graphitic with few disordered carbon and impurities. The results highlighted that synthesized MWCNTs were highly pure which eliminates the need for MWCNTs purification process

    Inter-comparison of multiple angle remotely sensed data across different spatial resolutions and sensors for determination of albedo

    No full text
    Surface albedo is one of the critical parameters required by studies of surface energy balance and climate models. Albedo is defined as the ratio of outgoing radiances to incoming irradiances over hemispherical view-illumination geometry. Remotely sensed albedo is usually based on multiple view angle observations and a Bidirectional Reflectance Distribution Function (BRDF) model. The accuracy of remotely sensed albedo depends on a variety of factors of which the main ones are the accuracy of atmospherically corrected observations, the reliability of observations, and the validity of the applied BRDF model. Fine spatial resolution airborne and satellite data are valuable for the validation of coarse spatial resolution satellite albedos as they may be validated using field measurements with higher reliability. In this study, a variety of remote sensing data and field measurements were used to estimate, validate and analyse albedo at different spatial resolutions. The main aim was to validate the MODIS albedo product under UK conditions using the methods of direct and indirect comparisons with other available data. The source of the fine spatial resolution data used was the NCAVEO Field Campaign 2006 that took place at the Chilbolton calibration test site in southern England. The CHRIS/PROBA albedo was used as a fine spatial resolution (34 m) albedo map to investigate the spatial variation of albedo. The results of this investigation provided valuable information about the possibility of the extension of the obtained albedo map from CHRIS/PROBA data. The MODIS albedo product with a coarser spatial resolution (500 m), relative to the NCAVEO datasets, was compared with the CHRIS/PROBA albedo map to examine the effect of spatial scale on the accuracy of albedo (direct comparison). The uncertainties in the obtained albedo maps, from both MODIS and CHRIS/PROBA, were mainly examined by testing the accuracy of the input reflectance data and the applied BRDF model (indirect comparison). The results showed the accuracy of the MODIS albedo product inferior to that claimed by the MODIS team

    A Review of the Effect Children With Autism Have on Their Typically Developing Sibling

    No full text
    Autism has just recently become a widely researched field and due to the sudden pique of interest, there has been little research conducted in regards to the effect children with autism have on their families, in particular on the siblings. Through the limited research that has been conducted, evidence has surfaced for both positive and negative effects on the relationships between children with autism and their typically developing siblings. By taking a deeper look into the social, emotional and academic aspects that are affected in typically developing siblings of children with autism, I hypothesize that having a sibling with autism will lead to internal emotional damage and restrict the non-autistic siblings’ social capabilities. There will be no significant results in regards to the normal sibling’s academic behavior. This paper aims to review the literature in hopes of exploring possible ways to treat or prevent the negative effects children with autism have on their typically developing sibling, in hopes of creating a healthier environment for the family
