One of the problems caused the reduction of pistachio proceeds is related to biennial- bearing or alternative bearing. Biennial- bearing is very important and is happened because of the fallen female bloom buds in vintage year. This test was done according to random blocks of 6 orchards in the type of Ahmad Aghaie with 4 iterations. Vegetative properties of branch are investigated. The results are shown that if the bunch numbers are increased, the possibility of falling is increased in bloom buds. The least possibility of falling of bloom buds is specified in trimming of one bunch and has significant difference with other trimming. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alternate%20bearing" title="alternate bearing">alternate bearing</a>, <a href="https://publications.waset.org/abstracts/search?q=pistachio" title=" pistachio"> pistachio</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster" title=" cluster"> cluster</a>, <a href="https://publications.waset.org/abstracts/search?q=bud" title=" bud"> bud</a> </p> <a href="https://publications.waset.org/abstracts/39450/the-effect-of-bunch-in-the-branch-on-vegetative-characteristics-of-pistacia-vera" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39450.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">437</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">12</span> Experimental Analysis of Tuned Liquid Damper (TLD) with Embossments Subject to Random Excitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Saberi">Mohamad Saberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arash%20Sohrabi"> Arash Sohrabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tuned liquid damper is one the passive structural control ways which has been used since mid-1980 decade for seismic control in civil engineering.

This fact has demonstrated during many earlier earthquakes and many researchers’ reports have concerned with it. According to these reports, features of the site materials and geometry of the ground surface are considered the main factors. This study concentrates on the specific form of topographies like hills. Assessing of spectral responses of different points on the hills and beside demonstrates considerable differences between 1D and 2D methods of geotechnical analyses. A general trend of amplifications on the top of the hills and de-amplifications near the toe of the hills has been appeared within the acceleration, velocity and displacement response spectrums of horizontal motion. Evaluating of spectral responses of different sizes of the hills revealed that as much as the hill-size enlarges differences between spectral responses of 1D and 2D analyses transfers to longer range of periods and becomes wider. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=topography%20effect" title="topography effect">topography effect</a>, <a href="https://publications.waset.org/abstracts/search?q=amplification%20ratio" title=" amplification ratio"> amplification ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20spectrum" title=" response spectrum"> response spectrum</a>, <a href="https://publications.waset.org/abstracts/search?q=earth%20resources%20engineering" title=" earth resources engineering"> earth resources engineering</a> </p> <a href="https://publications.waset.org/abstracts/7842/spectral-assessing-of-topographic-effects-on-seismic-behavior-of-trapezoidal-hill" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7842.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> The Application of Bayesian Heuristic for Scheduling in Real-Time Private Clouds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sahar%20Sohrabi">Sahar Sohrabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The emergence of Cloud data centers has revolutionized the IT industry. Private Clouds in specific provide Cloud services for certain group of customers/businesses. In a real-time private Cloud each task that is given to the system has a deadline that desirably should not be violated. Scheduling tasks in a real-time private CLoud determine the way available resources in the system are shared among incoming tasks. The aim of the scheduling policy is to optimize the system outcome which for a real-time private Cloud can include: energy consumption, deadline violation, execution time and the number of host switches. Different scheduling policies can be used for scheduling. Each lead to a sub-optimal outcome in a certain settings of the system. A Bayesian Scheduling strategy is proposed for scheduling to further improve the system outcome. The Bayesian strategy showed to outperform all selected policies. It also has the flexibility in dealing with complex pattern of incoming task and has the ability to adapt. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cloud%20computing" title="cloud computing">cloud computing</a>, <a href="https://publications.waset.org/abstracts/search?q=scheduling" title=" scheduling"> scheduling</a>, <a href="https://publications.waset.org/abstracts/search?q=real-time%20private%20cloud" title=" real-time private cloud"> real-time private cloud</a>, <a href="https://publications.waset.org/abstracts/search?q=bayesian" title=" bayesian"> bayesian</a> </p> <a href="https://publications.waset.org/abstracts/38592/the-application-of-bayesian-heuristic-for-scheduling-in-real-time-private-clouds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38592.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">359</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">7</span> Species Diversity of Some Remarkable New Records of Lichens from Chwarta District, Kurdistan Region of Iraq</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salah%20Abdulla%20Salih">Salah Abdulla Salih</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhamad%20Sohrabi"> Muhamad Sohrabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to study the species, morphology, habitats and geographical distribution of new records of lichens from the Chwarta districts Kurdistan Region of Iraq from September 2022 to June 2023.

Numerous investigations on fiber’s effect on the properties of cement-based composites have been conducted in the last few decades. The use of fibers such as carbon nanofibers (CNFs) and carbon nanotubes (CNTs) in these materials is an ongoing field and needs further researches and studies. Excellent mechanical, thermal, and electrical properties of carbon nanotubes and nanofibers have motivated the development of advanced nanocomposites with outstanding and multifunctional properties. In this study, the electrical resistance of CNF reinforced cement mortar was examined. Three different dosages of CNF were used, and the resistances were compared to plain cement mortar. One of the biggest challenges in this study is dispersing CNF particles in the mortar mixture. Therefore, polycarboxylate superplasticizer and ultrasonication of the mixture have been selected for the purpose of dispersing CNFs in the cement matrix. The obtained results indicated that the electrical resistance of the CNF reinforced mortar samples decreases with increasing CNF content, which would be the first step towards examining strain and damage monitoring ability of cementitious composites containing CNF for structural health monitoring purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20nanofiber" title="carbon nanofiber">carbon nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=cement%20and%20concrete" title=" cement and concrete"> cement and concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=CNF%20reinforced%20mortar" title=" CNF reinforced mortar"> CNF reinforced mortar</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20mater" title=" smart mater"> smart mater</a>, <a href="https://publications.waset.org/abstracts/search?q=strain%20monitoring" title=" strain monitoring"> strain monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=structural%20health%20monitoring" title=" structural health monitoring"> structural health monitoring</a> </p> <a href="https://publications.waset.org/abstracts/115287/the-effect-of-carbon-nanofibers-on-the-electrical-resistance-of-cementitious-composites" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/115287.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> The Effect of Foreign Language Classroom Anxiety and Tolerance of Ambiguity on EFL Learners’ Listening Proficiency</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Hadi%20Mahmoodi">Mohammad Hadi Mahmoodi</a>, <a href="https://publications.waset.org/abstracts/search?q=Azam%20Ghonchepoor"> Azam Ghonchepoor</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheilan%20Sohrabi"> Sheilan Sohrabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study was conducted to investigate the effect of foreign language classroom anxiety and ambiguity tolerance on EFL Learners’ listening proficiency. In so doing, 442 EFL learners were randomly selected form Azad University and some accredited language institutions in Hamaden, and were given the Foreign Language Classroom Anxiety Scale (FLCAS) (1983), and Second Language Tolerance of Ambiguity Scale (SLTAS) (1995). Participants’ listening proficiency level was determined through listening scores gained in standardized exams given by university professors or institutes in which they studied English. The results of two-way ANOVA revealed that listening proficiency was significantly affected by the interaction of anxiety and AT level of the participants. Each of the two variables were categorized in three levels of High, Mid, and Low. The highest mean score of listening belonged to the group with low degree of anxiety and high degree of ambiguity tolerance, and the lowest listening mean score was gained by the group with high level of anxiety and low level of tolerance of ambiguity. Also, the findings of multiple regressions confirmed that anxiety was the stronger predictor of listening comprehension in contrast with tolerance of ambiguity. Furthermore, the result of Pearson correlation coefficient showed that there was a significant negative relationship between the participants’ foreign language classroom anxiety and their ambiguity tolerance level. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Foreign%20Language%20Classroom%20Anxiety" title="Foreign Language Classroom Anxiety">Foreign Language Classroom Anxiety</a>, <a href="https://publications.waset.org/abstracts/search?q=Second%20language%20tolerance%20of%20ambiguity" title=" Second language tolerance of ambiguity"> Second language tolerance of ambiguity</a>, <a href="https://publications.waset.org/abstracts/search?q=Listening%20proficiency" title=" Listening proficiency"> Listening proficiency</a> </p> <a href="https://publications.waset.org/abstracts/19147/the-effect-of-foreign-language-classroom-anxiety-and-tolerance-of-ambiguity-on-efl-learners-listening-proficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19147.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">509</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> An Investigation of the Influence of the Iranian 1979 Revolution on Tehran’s Public Art </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Sohrabi%20Narciss">M.

After the Iranian Constitutional Revolution, the 1979 Revolution has had a profound impact on Tehran’s urban space. In 1979, the world watched as Iranians demonstrated en masse against the Pahlavi dynastdy which eventually led to its overthrow. Tehran’s public space is replete with images and artwork that depict the overthrow of the Pahlavi regime and the establishment of an Islamic government in Iran. The public artworks related to the 1979 Islamic Revolution reflect the riots, protests, and strikes that the Iranians underwent during the revolution. Many of these artworks try to revitalize the events that occurred in the 1970s by means of collective memory. Almost 4 decades have passed since the revolution and ever since the public artwork has been affected either directly or indirectly by the Iran-Iraq War, the Green Movement, and the rise and fall of various political forces. The present study is an attempt to investigate Tehran’s urban artwork such as urban sculptures and mural paintings organized and supervised by the government and the graffiti drawn by the critics or the opposition groups. To this end, in addition to the available documents, field research and questionnaires were used to qulaitatively analyze the data. This paper tries to address the following questions: 1) what changes have occurred in Tehran’s urban art? 2) Does the public, revolution-related artwork have an effect on people’s vitality? 3) do Iranians find these artworks appealing or not? <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public%20space" title="public space">public space</a>, <a href="https://publications.waset.org/abstracts/search?q=Tehran" title=" Tehran"> Tehran</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20art" title=" public art"> public art</a>, <a href="https://publications.waset.org/abstracts/search?q=movement" title=" movement"> movement</a>, <a href="https://publications.waset.org/abstracts/search?q=Islamic%20revolution" title=" Islamic revolution"> Islamic revolution</a> </p> <a href="https://publications.waset.org/abstracts/79635/an-investigation-of-the-influence-of-the-iranian-1979-revolution-on-tehrans-public-art" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79635.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">196</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Psychological Nano-Therapy: A New Method in Family Therapy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siamak%20Samani">Siamak Samani</a>, <a href="https://publications.waset.org/abstracts/search?q=Nadereh%20Sohrabi"> Nadereh Sohrabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Psychological nano-therapy is a new method based on systems theory. According to the theory, systems with severe dysfunctions are resistant to changes. Psychological nano-therapy helps the therapists to break this ice. Two key concepts in psychological nano-therapy are nano-functions and nano-behaviors. The most important step in psychological nano-therapy in family therapy is selecting the most effective nano-function and nano-behavior. The aim of this study was to check the effectiveness of psychological nano-therapy for family therapy. One group pre-test-post-test design (quasi-experimental Design) was applied for research. The sample consisted of ten families with severe marital conflict. The important character of these families was resistance for participating in family therapy. In this study, sending respectful (nano-function) text massages (nano-behavior) with cell phone were applied as a treatment. Cohesion/respect sub scale from self-report family processes scale and family readiness for therapy scale were used to assess all family members in pre-test and post-test. In this study, one of family members was asked to send a respectful text massage to other family members every day for a week. The content of the text massages were selected and checked by therapist. To compare the scores of families in pre-test and post-test paired sample t-test was used. The results of the test showed significant differences in both cohesion/respect score and family readiness for therapy between per-test and post-test. The results revealed that these families have found a better atmosphere for participation in a complete family therapy program. Indeed, this study showed that psychological nano-therapy is an effective method to make family readiness for therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=family%20therapy" title="family therapy">family therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20conflicts" title=" family conflicts"> family conflicts</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-therapy" title=" nano-therapy"> nano-therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=family%20readiness" title=" family readiness"> family readiness</a> </p> <a href="https://publications.waset.org/abstracts/17838/psychological-nano-therapy-a-new-method-in-family-therapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17838.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">659</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Coated Chromium Thin Film on Zirconium for Corrosion Resistance of Nuclear Fuel Rods by Plasma Focus Device</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Raeisdana">Amir Raeisdana</a>, <a href="https://publications.waset.org/abstracts/search?q=Davood%20Sohrabi"> Davood Sohrabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Nohekhan"> Mojtaba Nohekhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ameneh%20Kargarian"> Ameneh Kargarian</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Ghapanvari"> Maryam Ghapanvari</a>, <a href="https://publications.waset.org/abstracts/search?q=Alireza%20Aslezaeem"> Alireza Aslezaeem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Improvement of zirconium properties by chromium coating and nitrogen implantation is ideal to protect the nuclear fuel rods against corrosion and secondary hydrogenation. Metallic chromium (Cr) has attracted attention as a potential coating material on zirconium alloys, to limit external cladding corrosion. In this research, high energy plasma focus device was used to coat the chromium and implant the nitrogen ions in the zirconium substrate. This device emits high-energy nitrogen ions of 10 keV-1 MeV and with a flux of 10^16 ions/cm^2 in each shot toward the target so it is attractive for implantation on the substrate materials at the room temperature. Six zirconium samples in 2cm×2cm dimensions with 1mm thickness were located at a distance of 20cm from the place where the pinch is formed. The experiments are carried out in 0.5 mbar of the nitrogen gas pressure and 15 kV of the charging voltage. Pure Cr disc was installed on the anode head for sputtering of the chromium and deposition on zirconium substrate. When the pinch plasma column decays due to various instabilities, intense and high-energy N2 ions are accelerated towards the zirconium substrate also sputtered Cr is deposited on the zirconium substrate. XRD and XRF analysis were used to study the structural properties of the samples. XRF analysis indicates 77.1% of Zr and 11.1% of Cr in the surface of the sample. XRD spectra shows the formation of ZrN, CrN and CrZr composites after nitrogen implantation and chromium coating. XRD spectra shows the chromium peak height equal to 152.80 a.u. for the major sample (θ=0֯) and 92.99 a.u. for the minor sample (θ=6֯), so implantation and coating along the main axis of the device is significantly more than other directions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ZrN%20and%20CrN%20and%20CrZr%20composites" title="ZrN and CrN and CrZr composites">ZrN and CrN and CrZr composites</a>, <a href="https://publications.waset.org/abstracts/search?q=angular%20distribution%20for%20Cr%20deposition%20rate" title=" angular distribution for Cr deposition rate"> angular distribution for Cr deposition rate</a>, <a href="https://publications.waset.org/abstracts/search?q=zirconium%20corrosion%20resistance" title=" zirconium corrosion resistance"> zirconium corrosion resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20fuel%20rods" title=" nuclear fuel rods"> nuclear fuel rods</a>, <a href="https://publications.waset.org/abstracts/search?q=plasma%20focus%20device" title=" plasma focus device"> plasma focus device</a> </p> <a href="https://publications.waset.org/abstracts/190103/coated-chromium-thin-film-on-zirconium-for-corrosion-resistance-of-nuclear-fuel-rods-by-plasma-focus-device" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/190103.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">23</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> The Effect of Spark Physical Program (Sports, Play and Active Recreation for Kids) on Quality of Life and Spirometry in 6-18-Year-Old Children with Cystic Fibrosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeedeh%20Eshkil">Saeedeh Eshkil</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyedeh%20Farnaz%20Mousavi"> Seyedeh Farnaz Mousavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Reza%20Kianifar"> Hamid Reza Kianifar</a>, <a href="https://publications.waset.org/abstracts/search?q=Seyed%20Java%20Sayyedi"> Seyed Java Sayyedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Sohrabi"> Mehdi Sohrabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20%20Bakhtiari"> Elham Bakhtiari</a>, <a href="https://publications.waset.org/abstracts/search?q=Morteza%20Mashoughi"> Morteza Mashoughi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ezzat%20Khodashenas"> Ezzat Khodashenas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The effect of the SPARK physical education program on lung function in cystic fibrosis patients is not yet determined.).SPARK is Sports, play and active recreation for kids, including moving skills, aerobic games, jogging or walking, aerobic dance and jump rope. Regarding the high prevalence of cystic fibrosis and its destructive effects on the lungs, the aim of this study is to evaluate lung function and quality of life before and after undergoing the SPARK physical education program in children with cystic fibrosis. Method: In this quasi-experimental study, all patients with cystic fibrosis aged 6-18 years referred to the cystic fibrosis clinic of Dr. Sheikh Hospital were enrolled. The patients went under 12 weeks of SPARK training program (3 sessions per week, each session 45 minutes). The quality of life questionnaire ( Cystic Fibrosis Questionnaire includes self-examination, parental ) for patients with cystic fibrosis and spirometry indices (FEV1, FVC, FEV1/FVC, FEF25-75) was filled out before and after intervention for all patients. Results The mean and standard deviation of patients' age were 9.85±2.67 years, and 65% of patients were female. The FEV1 was significantly different before and after the SPARK physical education program (P=0.03), and the respiratory component of quality of life significantly increased after intervention (P=0.002). The overall score of quality of life from parents’ point of view was 2.87 ± 0.38, which increased to 2.99 ± 0.38 after the intervention. Conclusion: The SPARK training program may improve the spirometric parameters in children with cystic fibrosis. It also had a significant effect on improving the quality of life of patients, especially in the respiratory component. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cystic%20fibrosis" title="cystic fibrosis">cystic fibrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=pediatrics" title=" pediatrics"> pediatrics</a>, <a href="https://publications.waset.org/abstracts/search?q=SPARK%20motor%20program" title=" SPARK motor program"> SPARK motor program</a>, <a href="https://publications.waset.org/abstracts/search?q=spirometry" title=" spirometry"> spirometry</a> </p> <a href="https://publications.waset.org/abstracts/191726/the-effect-of-spark-physical-program-sports-play-and-active-recreation-for-kids-on-quality-of-life-and-spirometry-in-6-18-year-old-children-with-cystic-fibrosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191726.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">20</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
