The prepared photocatalysts were characterized by x-ray diffraction, diffuse reflectance, TEM and the surface area. The prepared samples have a mixture of cubic perovskite structure (main) and orthorhombic phases. The effect of different loads of copper as dopant on the structural properties as well as the photocatalytic activity was demonstrated. The lattice parameter and the unit cell volume of the prepared materials are given. Doping with copper increased the photocatalytic activity of BaFeO3 several times in abstraction of hazardous atrazine that causes acute problems in drinking water treatment facilities. This may be reasoned to low band gap energy of copper doped BaFe(1-x)CuxO3 attributed to oxygen vacancies formation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photocatalysis" title="photocatalysis">photocatalysis</a>, <a href="https://publications.waset.org/abstracts/search?q=nano-sized" title=" nano-sized"> nano-sized</a>, <a href="https://publications.waset.org/abstracts/search?q=BaFeO3" title=" BaFeO3"> BaFeO3</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20doping" title=" copper doping"> copper doping</a>, <a href="https://publications.waset.org/abstracts/search?q=atrazine" title=" atrazine"> atrazine</a> </p> <a href="https://publications.waset.org/abstracts/61647/copper-doping-for-enhancing-photocatalytic-efficiency-of-barium-ferrite-in-degradation-of-atrazine-under-visible-light" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61647.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">349</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">60</span> Evaluation of the Predatory Mites' Manner against Root-Knot Nematode Using Water Agar Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdelrady%20K.%20Nasr">Abdelrady K.

Moreover, the soil predatory mites (Protogamasellopsisdenticus (Nasr), Gaeolaelaps longus (Hafez, El-Badry and Nasr) and Cosmolaelapskeni(Hafez, El-Badry and Nasr) are one of the excellent agents for biocontrol, this study was designed to evaluate the predation of the root-knot nematode (M. incognita) using water agar technique. The water agar medium was used as an experimental medium to rear both the mentioned mites and egg masses; these media allowed observe the development and predacious manner. The present study revealed that the predatory mites successfully developed and reproduced their egg masses. The mean life cycle of the tested mites P. denticus, G. longus, and C.keni were 10.33, 12.00, and 9.77 days, respectively. The mean total life span of the female of P. denticus, G. longus, and C. keni on egg-mases of M. incognita were obtained 63.44, 77.55 and 70.11 days, respectively, and the mean total fecundity of predatory mites, P. denticus, G.longus, and C. keni on egg-mases nematode were observed 62.66, 31.61 and 11.83 eggs, respectively. The mean total number of eggs laid by female P. denticus was significantly higher than other predatory mites, G. longus and C. keni. According to the obtained results, the tested predacious mites can be applied to combat the spreading of M. incognita in the agriculture field as a safe and effective biological control. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20control" title="biological control">biological control</a>, <a href="https://publications.waset.org/abstracts/search?q=plant-parasitic%20nematodes" title=" plant-parasitic nematodes"> plant-parasitic nematodes</a>, <a href="https://publications.waset.org/abstracts/search?q=predaceous%20mites" title=" predaceous mites"> predaceous mites</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20agar" title=" water agar"> water agar</a> </p> <a href="https://publications.waset.org/abstracts/174142/evaluation-of-the-predatory-mites-manner-against-root-knot-nematode-using-water-agar-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/174142.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">79</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">59</span> The Impact of Human Rights on Society and Legislations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eid%20Nasr%20Saad%20Nasr">Eid Nasr Saad Nasr</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Although human rights protection in the industrial sector has increased, human rights violations continue to occur. Although the government has passed human rights laws, labor laws, and an international treaty ratified by the United States, human rights crimes continue to occur and go undetected. The growing number of textile companies in Bekasi is also leading to an increase in human rights violations as the government has no obligation to protect them. The United States government and business leaders should respect, protect and defend the human rights of workers. The article discusses the human rights violations faced by garment factory workers in the context of the law, as well as ideas for improving the protection of workers' rights. The connection between development and human rights has long been the subject of academic debate. Therefore, to understand the dynamics between these two concepts, a number of principles have been adopted, ranging from the right to development to a human rights-based approach to development. Despite these attempts, the precise connection between development and human rights is not yet fully understood. However, the inherent interdependence between these two concepts and the idea that development efforts must respect human rights guarantees has gained momentum in recent years. It will then be examined whether the right to sustainable development is recognized. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sustainable%20development" title="sustainable development">sustainable development</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights" title=" human rights"> human rights</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20right%20to%20development" title=" the right to development"> the right to development</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20human%20rights-based%20approach%20to%20development" title=" the human rights-based approach to development"> the human rights-based approach to development</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20rights" title=" environmental rights"> environmental rights</a>, <a href="https://publications.waset.org/abstracts/search?q=economic%20development" title=" economic development"> economic development</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20sustainability%20human%20rights%20protection" title=" social sustainability human rights protection"> social sustainability human rights protection</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20rights%20violations" title=" human rights violations"> human rights violations</a>, <a href="https://publications.waset.org/abstracts/search?q=workers%E2%80%99%20rights" title=" workers’ rights"> workers’ rights</a>, <a href="https://publications.waset.org/abstracts/search?q=justice" title=" justice"> justice</a>, <a href="https://publications.waset.org/abstracts/search?q=security" title=" security"> security</a> </p> <a href="https://publications.waset.org/abstracts/183823/the-impact-of-human-rights-on-society-and-legislations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183823.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">59</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">58</span> Bio-Genetic Activities Associated with Resistant in Peppers to Phytophthora capsici</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Nasr-Esfahani">Mehdi Nasr-Esfahani</a>, <a href="https://publications.waset.org/abstracts/search?q=Leila%20Mohammad%20Bagheri"> Leila Mohammad Bagheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Ava%20Nasr-Esfahani"> Ava Nasr-Esfahani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Root and collar rot disease caused by Phytophthora capsici (Leonian) is one of the most serious diseases in pepper, Capsicum annuum L. In this study, a diverse collection of 37 commercial edible and ornamental pepper genotypes infected with P. capsici were investigated for biomass parameters and enzymatic activity of peroxidase or peroxide reductases (EC), superoxide dismutase (SOD), polyphenol oxidase (PPOs), catalase (CAT) and phenylalanine ammonia-lyase (PAL). Seven candidate DEG genes were also evaluated on resistant and susceptible pepper cultivars, through measuring product formation, using spectrophotometry and real-time polymerase chain reaction. All the five enzymes and seven defense-gene candidates were up-regulated in all inoculated pepper accessions to P. capsici. But, the enzymes and DEG genes were highly expressed in resistant cv. 19OrnP-PBI, 37ChillP-Paleo, and “23CherryP-Orsh". The expression level of enzymes were 1.5 to 5.6-fold higher in the resistant peppers, than the control non-inoculated genotypes. Also, the transcriptional levels of related candidate DEG genes were 3.16 to 5.90-fold higher in the resistant genotypes. There was a direct and high correlation coefficient between resistance, bio-mass parameters, enzymatic activity, and resistance gene expression. The related enzymes and candidate genes expressed herein will provide a basis for further gene cloning and functional verification studies, and also will aid in an understanding of the regulatory mechanism of pepper resistance to P. capsici. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AP2%2FERF" title="AP2/ERF">AP2/ERF</a>, <a href="https://publications.waset.org/abstracts/search?q=cDNA" title=" cDNA"> cDNA</a>, <a href="https://publications.waset.org/abstracts/search?q=enzymes" title=" enzymes"> enzymes</a>, <a href="https://publications.waset.org/abstracts/search?q=MIP%20gene" title=" MIP gene"> MIP gene</a>, <a href="https://publications.waset.org/abstracts/search?q=q-RTPCR" title=" q-RTPCR"> q-RTPCR</a>, <a href="https://publications.waset.org/abstracts/search?q=XLOC" title=" XLOC"> XLOC</a> </p> <a href="https://publications.waset.org/abstracts/119322/bio-genetic-activities-associated-with-resistant-in-peppers-to-phytophthora-capsici" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119322.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">152</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">57</span> Latest Advances in the Management of Liver Diseases</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabab%20Makki">Rabab Makki</a>, <a href="https://publications.waset.org/abstracts/search?q=Deputy%20Chief%20Dietitian"> Deputy Chief Dietitian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Malnutrition is commonly seen in Liver Disease patients. Prevalence of malnutrition in cirrhosis, is as high as 65-90%. Protein depletion and reduced muscle function are common. There are many mechanisms of malnutrition in liver cirrhosis e.g. insulin resistance, low respiratory quotient, increased glucogenesis etc. Nutrition support improves outcome in patients unable to maintain an intake of 35-40 Kcal/kg and 1.2-1.5 gm/kg/day. Simple methods of assessment such as subjective global assessment, calorie counting, MMC are useful. The value of BCAAs remains uncertain despite a considerable number of studies.

Retinal microvasculature can be directly and non-invasively examined. Aim: to evaluate retinal vascular tortuosity in patients with COPD, OSA, and overlap syndrome. Subjects and method: Sixty subjects were included; 15 OSA patients, 15 COPD patients, 15 COPD-OSA overlap patients, and 15 matched controls. They underwent digital retinal photography, polysomnography, arterial blood gases, spirometry, ESS, and stop-bang questionnaires. Results: Tortuosity of most retinal vessels was higher in all patient groups compared to the control group; tortuosity was more marked in overlap syndrome. There was a negative correlation between tortuosity of retinal vessels and PO2, O2 saturation, and minimum O2 desaturation, and a positive correlation with PCO2, AHI, O2 desaturation index, BMI and smoking index. Conclusion: Retinal vascular tortuosity occurs in OSA, COPD and overlap syndrome. Retinal vascular tortuosity is correlated with arterial blood gases parameters, polysomnographic findings, smoking index and BMI. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=OSA" title="OSA">OSA</a>, <a href="https://publications.waset.org/abstracts/search?q=COPD" title=" COPD"> COPD</a>, <a href="https://publications.waset.org/abstracts/search?q=overlap%20syndrome" title=" overlap syndrome"> overlap syndrome</a>, <a href="https://publications.waset.org/abstracts/search?q=retinal%20vascular%20tortuosity" title=" retinal vascular tortuosity"> retinal vascular tortuosity</a> </p> <a href="https://publications.waset.org/abstracts/168040/retinal-vascular-tortuosity-in-obstructive-sleep-apnea-copd-overlap-patients" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168040.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">75</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">54</span> Novel Nanomagnetic Beads Based- Latex Agglutination Assay for Rapid Diagnosis of Human Schistosomiasis Haematobium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Aly">Ibrahim Aly</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabab%20Zalat"> Rabab Zalat</a>, <a href="https://publications.waset.org/abstracts/search?q=Bahaa%20EL%20Deen%20W.%20El%20Aswad"> Bahaa EL Deen W.

This paper presents a non-linear finite element based modeling approach to estimate behavior of RC flat plate inclined column connection. Results from simulations of RC flat plate-straight column connection show good agreement with experimental response of specimens tested by other researchers.

In immunocompromised hosts, infection Canbe life-threatening as no effective treatments are currently available to control infection. To increase our understanding of the mechanisms that play a role in host-parasite interactions at the level of the immune response, we investigated the effects of Cryptosporidium parvum antigen (CPA) on bone marrow-derived (DCS). Herein we examined cytokine secretion and cell surface marker expression on DCs exposed to CPA. We also measured cytokine production in CD4+ cells co-cultured with CPA primed DCs in the presence of anti-CD3. CPA induced a significant increase in the production of interleukin(IL)-12p40, IL-10, IL-6, and TNF-α by DCs and enhanced the expression of the cell surface markers TLR4, CD80, CD86, and MHC11. CPA primed DC co-cultured in the presence of anti-CD3 with CD4+ T-cells inhibited the secretion of Th2 associated cytokines, notably IL-5 and IL-13, with no effects on the secretions of interferon (IFN)-γ, IL-2, IL-17, and IL-10. These findings support studies in the literature that CPA can induce the full maturation of DCs that subsequently initiate Th1 immune responses critical to the resolution of C. parvum infection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryptosporidium%20parvum" title="cryptosporidium parvum">cryptosporidium parvum</a>, <a href="https://publications.waset.org/abstracts/search?q=dendritic%20cells" title=" dendritic cells"> dendritic cells</a>, <a href="https://publications.waset.org/abstracts/search?q=IL-12%20p70" title=" IL-12 p70"> IL-12 p70</a>, <a href="https://publications.waset.org/abstracts/search?q=cell%20surface%20marker" title=" cell surface marker"> cell surface marker</a> </p> <a href="https://publications.waset.org/abstracts/143746/cryptosporidium-parvum-oocytic-antigen-induced-a-pro-inflammatory-dc-phenotype" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143746.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">173</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">49</span> The Importance of Contemporary Interior Design in today's Day and Age</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabab%20Bamboat">Rabab Bamboat</a>, <a href="https://publications.waset.org/abstracts/search?q=Reenu%20Singh"> Reenu Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Today, contemporary modular interior design components provide us the ease to rethink or change our spaces with flexibility. Specifically, contemporary design is perfect for all those people who feel the need to “change” to feel at home again. The variables such as color, furniture, furnishings, fixtures are some of the elements that are changed and re-furnished at periodic intervals. With contemporary interior design, one can customize the interiors to suit the respective personality and passions. A questionnaire survey was conducted to understand how contemporary interior design and its variables play an important role and should be applied while designing an interior space in today's time. Thus, helping us understand better the needs of people and what they would prefer whilst one keeps practicality and functionality in mind. Based on the analysis and extensive literature review, the study develops an understanding of how contemporary interior design should be applied in today's day and age, making living more practical easy but also stylish. The findings provide a more sustainable, functional, simple, and classy way of living while having customed furniture, color, art in an interior space. These variables provided solutions for effective ideation to support the functionality in a minimal and contemporary interior space. This concludes in providing a better understanding to the designers to incorporate a minimalist or contemporary lifestyle while keeping their requirements and other factors in mind. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contemporary" title="contemporary">contemporary</a>, <a href="https://publications.waset.org/abstracts/search?q=minimal" title=" minimal"> minimal</a>, <a href="https://publications.waset.org/abstracts/search?q=practicality" title=" practicality"> practicality</a>, <a href="https://publications.waset.org/abstracts/search?q=personality" title=" personality"> personality</a> </p> <a href="https://publications.waset.org/abstracts/145877/the-importance-of-contemporary-interior-design-in-todays-day-and-age" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145877.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">176</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">48</span> An Automatic Feature Extraction Technique for 2D Punch Shapes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Awais%20Ahmad%20Khan">Awais Ahmad Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Abouel%20Nasr"> Emad Abouel Nasr</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20M.%20A.%20Hussein"> H.

Modern epistemology, cognitive psychology and psychoanalysis begin to argue and prove that emotions are relevant epistemological functions. They are 1) the selection function: that allows the perception and reason choose, to multiple alternative explanation of a particular fact, those are relevant and discard those that are not, 2) heuristic function: that is related to the activation cognitive processes that are effective in the process of knowing; and 3) the function that called carrier content: on the latter it arises that emotions give the material reasoning that later transformed into linguistic propositions. According to these hypotheses, scientific knowledge seems to come from emotions that meet these functions. In this paper I argue that science education should start from the presence of certain emotions in the learner if it is to form citizens with scientific or cultural future scientists. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epistemic%20emotions" title="epistemic emotions">epistemic emotions</a>, <a href="https://publications.waset.org/abstracts/search?q=science%20education" title=" science education"> science education</a>, <a href="https://publications.waset.org/abstracts/search?q=formation%20of%20citizens%20and%20scientists." title=" formation of citizens and scientists."> formation of citizens and scientists.</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophy%20of%20emotions" title=" philosophy of emotions"> philosophy of emotions</a> </p> <a href="https://publications.waset.org/abstracts/147079/epistemological-functions-of-emotions-and-their-relevance-to-the-formation-of-citizens-and-scientists" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147079.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">125</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">46</span> Implementation of a Multimodal Biometrics Recognition System with Combined Palm Print and Iris Features</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rabab%20M.%20Ramadan">Rabab M.

Therefore, multimodal biometric systems are proposed to solve the above stated problems. This paper introduces a bimodal biometric recognition system based on the extracted features of the human palm print and iris. Palm print biometric is fairly a new evolving technology that is used to identify people by their palm features. The iris is a strong competitor together with face and fingerprints for presence in multimodal recognition systems. In this research, we introduced an algorithm to the combination of the palm and iris-extracted features using a texture-based descriptor, the Scale Invariant Feature Transform (SIFT). Since the feature sets are non-homogeneous as features of different biometric modalities are used, these features will be concatenated to form a single feature vector. Particle swarm optimization (PSO) is used as a feature selection technique to reduce the dimensionality of the feature. The proposed algorithm will be applied to the Institute of Technology of Delhi (IITD) database and its performance will be compared with various iris recognition algorithms found in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iris%20recognition" title="iris recognition">iris recognition</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20extraction" title=" feature extraction"> feature extraction</a>, <a href="https://publications.waset.org/abstracts/search?q=feature%20selection" title=" feature selection"> feature selection</a>, <a href="https://publications.waset.org/abstracts/search?q=palm%20print" title=" palm print"> palm print</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20Scale%20Invariant%20Feature%20Transform%20%28SIFT%29" title=" the Scale Invariant Feature Transform (SIFT)"> the Scale Invariant Feature Transform (SIFT)</a> </p> <a href="https://publications.waset.org/abstracts/90535/implementation-of-a-multimodal-biometrics-recognition-system-with-combined-palm-print-and-iris-features" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90535.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">235</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">45</span> Showing Broccoli and Cabbage Genotypes Biodiversity Using Randomly Amplified Polymorphic DNAs (RAPD)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20M.%20A.%20Abdalla">M.

We found evidence to support an unconditional long run effect of FD on environmental conditions (EC), with quite significant differences between the two groups of countries. While FD leads to environmental degradation (ED) in non-oil-producing countries, it helps protect the environment in oil-producing ones. Regarding the effects of IQ on EC, they are not significant in both short- and long run for non-oil-producing countries, but they are significant for oil-producing ones only in the long run. In the short run, IQ indicators haven’t significant effects on EC for the two groups of countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=financial%20development" title="financial development">financial development</a>, <a href="https://publications.waset.org/abstracts/search?q=institutional%20quality" title=" institutional quality"> institutional quality</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20conditions" title=" environmental conditions"> environmental conditions</a>, <a href="https://publications.waset.org/abstracts/search?q=Panel%20ARDL" title=" Panel ARDL"> Panel ARDL</a> </p> <a href="https://publications.waset.org/abstracts/169093/financial-development-institutional-quality-and-environmental-conditions-in-the-middle-east-and-north-africa-region-evidence-from-oil-and-non-oil-producing-countries" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169093.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">82</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">43</span> Optimization of Multi-Zone Unconventional (Shale) Gas Reservoir Using Hydraulic Fracturing Technique</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20C.%20Amadi">F.

It allows more oil and gas production in tight reservoirs as compared to conventional means. The main aim of the study is to optimize the hydraulic fracturing as technique and for this purpose three multi-zones layer formation is considered and fractured contemporaneously. The three zones are named as Zone1 (upper zone), Zone2 (middle zone) and Zone3 (lower zone) respectively and they all occur in shale rock. Simulation was performed with Mfrac integrated software which gives a variety of 3D fracture options. This simulation process yielded an average fracture efficiency of 93.8%for the three respective zones and an increase of the average permeability of the rock system. An average fracture length of 909 ft with net height (propped height) of 210 ft (average) was achieved. Optimum fracturing results was also achieved with maximum fracture width of 0.379 inches at an injection rate of 13.01 bpm with 17995 Mscf of gas production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20fracturing" title="hydraulic fracturing">hydraulic fracturing</a>, <a href="https://publications.waset.org/abstracts/search?q=optimisation" title=" optimisation"> optimisation</a>, <a href="https://publications.waset.org/abstracts/search?q=shale" title=" shale"> shale</a>, <a href="https://publications.waset.org/abstracts/search?q=tight%20reservoir" title=" tight reservoir"> tight reservoir</a> </p> <a href="https://publications.waset.org/abstracts/35122/optimization-of-multi-zone-unconventional-shale-gas-reservoir-using-hydraulic-fracturing-technique" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35122.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">428</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">42</span> Debris' Effect on Bearing Capacity of Defective Piles in Sand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20Nasr">A.

ET induced alopecia(EIA) is less frequently noted by patients and is less reported in the literature. The aim of our study was to report ET alopecia characteristics and their influence on patient and treatment observance. Method: We conducted a retrospective study including luminal BC patients treated in the oncology department of the military hospital of Tunis between January 2015 and December 2020. Patients treated with previous chemotherapy-inducing alopecia were excluded. Results: 145 female patients were included. The median age was 59 years. EIA was reported in 44% of cases. Alopecia was attributed to aromatase inhibitors in 53% and tamoxifen in 21%. Severity was grade 1 in 80% and grade 2 in the remaining cases. ET discontinuation because of alopecia was noted in 6.5 % of patients. Moderate improvement of alopecia was observed with topical minoxidil and Thallium metallicum 9CH homeopathy during ET in 60% of patients. Conclusions: EIA is frequent in BC patients and should be considered to improve treatment observance and patients’ quality of life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=endocrine%20therapy" title="endocrine therapy">endocrine therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=alopecia" title=" alopecia"> alopecia</a>, <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title=" breast cancer"> breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/137492/endocrine-therapy-induced-alopecia-in-patients-with-breast-cancer-in-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137492.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">125</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">40</span> Optimization of Groundwater Utilization in Fish Aquaculture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Ahmed%20Eldesouky">M.

The most common problem limiting the use of groundwater in Egypt is its high iron, manganese and ammonia content. This problem is often overcome by applying the treatment before use. Aeration in many cases is not enough to oxidize iron and manganese in complex forms with organics. Most of the treatment we use potassium permanganate as an oxidizer followed by a pressurized closed green sand filter. The aim of present study is to investigate the optimum characteristics of groundwater to give lowest iron, manganese and ammonia, maximum production and quality of fish in aquaculture in El-Max Research Station. The major design goal of the system was determined the optimum time for harvesting the treated water, pH, and Glauconite weight to use it for aquaculture process in the research site and achieve the Egyptian law (48/1982) and EPA level required for aquaculture. The water characteristics are [Fe = 0.116 mg/L, Mn = 1.36 mg/L,TN = 0.44 mg/L , TP = 0.07 mg/L , Ammonia = 0.386 mg/L] by using the glauconite filter we obtained high efficiency for removal for [(Fe, Mn and Ammonia] ,but in the Lab we obtained result for (Fe, 43-97), ( Mn,92-99 ), and ( Ammonia, 66-88 )]. We summarized the results to show the optimum time, pH, Glauconite weight, and the best model for design in the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquaculture" title="aquaculture">aquaculture</a>, <a href="https://publications.waset.org/abstracts/search?q=ammonia%20in%20groundwater" title=" ammonia in groundwater"> ammonia in groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=iron%20and%20manganese%20in%20water" title=" iron and manganese in water"> iron and manganese in water</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20treatment" title=" groundwater treatment"> groundwater treatment</a> </p> <a href="https://publications.waset.org/abstracts/46529/optimization-of-groundwater-utilization-in-fish-aquaculture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46529.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">233</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">39</span> Role of Selenium and Vitamin E in Occupational Exposure to Heavy Metals (Mercury, Lead and Cadmium): Impact of Working in Lamp Factory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tarek%20Elnimr">Tarek Elnimr</a>, <a href="https://publications.waset.org/abstracts/search?q=Rabab%20El-kelany"> Rabab El-kelany</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metals are environmental contaminants that may pose long-term health risks. Unfortunately, the consequent implementation of preventive measures was generally delayed, causing important negative effects to the exposed populations. The objective of this study was to determine whether co-consumption of nutritional supplements as selenium and vitamin E would treat the hazardous effects of exposure to mercury, lead and cadmium. 108 workers (60 males and 48 females) were the subject of this study, their ages ranged from 19-63 years, (M = 29.5±10.12). They were working in lamp factory for an average of 0.5-40 years (M= 5.3±8.8). Twenty control subjects matched for age and gender were used for comparison. All workers were subjected to neuropsychiatric evaluation. General Health Questionnaire (GHQ-28) revealed that 44.4% were complaining of anxiety, 52.7% of depression, 41.6% of social dysfunction and 22.2% of somatic symptoms. Cognitive tests revealed that long-term memory was not affected significantly when compared with controls, while short term memory and perceptual ability were affected significantly. Blood metal levels were measured by Inductively Coupled Plasma – optical emission spectrometry(ICP-OES), and revealed that the mean blood mercury, lead and cadmium concentrations before treatment were 1.6 mg/l, 0.39 mg/l and 1.7 µg/l, while they decreased significantly after treatment to 1.2 mg/l, 0.29 mg/l and 1.3 µg/l respectively. Anti-oxidative enzymes (paraoxonase and catalase) and lipid peroxidation product (malondialdehyde) were measured before and after treatment with selenium and vitamin E, and showed significant improvement. It could be concluded that co-consumption of selenium and vitamin E produces significant decrease in mercury, lead and cadmium levels in blood. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mercury" title="mercury">mercury</a>, <a href="https://publications.waset.org/abstracts/search?q=lead" title=" lead"> lead</a>, <a href="https://publications.waset.org/abstracts/search?q=cadmium" title=" cadmium"> cadmium</a>, <a href="https://publications.waset.org/abstracts/search?q=neuropsychiatric%20impairment" title=" neuropsychiatric impairment"> neuropsychiatric impairment</a>, <a href="https://publications.waset.org/abstracts/search?q=selenium" title=" selenium"> selenium</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20E" title=" vitamin E"> vitamin E</a> </p> <a href="https://publications.waset.org/abstracts/38315/role-of-selenium-and-vitamin-e-in-occupational-exposure-to-heavy-metals-mercury-lead-and-cadmium-impact-of-working-in-lamp-factory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38315.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">345</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">38</span> Gas Lift Optimization to Improve Well Performance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20A.%20G.%20H.%20Abdalsadig">Mohamed A.

A proper lift optimization can reduce the operating cost, increase the net present value (NPV) and maximize the recovery from the asset. A widely accepted definition of gas lift optimization is to obtain the maximum output under specified operating conditions. In addition, gas lift, a costly and indispensable means to recover oil from high depth reservoir entails solving the gas lift optimization problems. Gas lift optimization is a continuous process; there are two levels of production optimization. The total field optimization involves optimizing the surface facilities and the injection rate that can be achieved by standard tools softwares. Well level optimization can be achieved by optimizing the well parameters such as point of injection, injection rate, and injection pressure. All these aspects have been investigated and presented in this study by using experimental data and PROSPER simulation program. The results show that the well head pressure has a large influence on the gas lift performance and also proved that smart gas lift valve can be used to improve gas lift performance by controlling gas injection from down hole. Obtaining the optimum gas injection rate is important because excessive gas injection reduces production rate and consequently increases the operation cost. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20rate" title=" production rate"> production rate</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20pressure%20effect" title=" reservoir pressure effect"> reservoir pressure effect</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20injection%20rate%20effect" title=" gas injection rate effect"> gas injection rate effect</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20injection%20pressure" title=" gas injection pressure"> gas injection pressure</a> </p> <a href="https://publications.waset.org/abstracts/46454/gas-lift-optimization-to-improve-well-performance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46454.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">413</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">37</span> Environmental Study on Urban Disinfection Using an On-site Generation System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V%C3%ADctor%20Mart%C3%ADnez%20del%20Rey">Víctor Martínez del Rey</a>, <a href="https://publications.waset.org/abstracts/search?q=Kourosh%20Nasr%20Esfahani"> Kourosh Nasr Esfahani</a>, <a href="https://publications.waset.org/abstracts/search?q=Amir%20Masoud%20Samani%20Majd"> Amir Masoud Samani Majd</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this experimental study, the behaviors of Mixed Oxidant solution components (MOS) and sodium hypochlorite (HYPO) as the most commonly applied surface disinfectant were compared through the effectiveness of chlorine disinfection as a function of the contact time and residual chlorine. In this regard, the variation of pH, free available chlorine (FAC) concentration, and electric conductivity (EC) of disinfection solutions in different concentrations were monitored over 48 h contact time. In parallel, the plant stress activated by chlorine-based disinfectants was assessed by comparing MOS and HYPO. The elements of pH and EC in the plant-soil and their environmental impacts, spread by disinfection solutions were analyzed through several concentrations of FAC including 500 mg/L, 1000 mg/L, and 5000 mg/L in irrigated water. All the experiments were carried out at the service station of Sant Cugat, Spain. The outcomes indicated lower pH and higher durability of MOS than HYPO at the same concentration of FAC which resulted in promising stability of FAC within MOS. Furthermore, the pH and EC value of plant-soil irrigated by NaOCl solution were higher than that of MOS solution at the same FAC concentration. On-site generation of MOS as a safe chlorination option might be considered an imaginary future of smart cities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=disinfection" title="disinfection">disinfection</a>, <a href="https://publications.waset.org/abstracts/search?q=free%20available%20chlorine" title=" free available chlorine"> free available chlorine</a>, <a href="https://publications.waset.org/abstracts/search?q=on-site%20generation" title=" on-site generation"> on-site generation</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20hypochlorite" title=" sodium hypochlorite"> sodium hypochlorite</a> </p> <a href="https://publications.waset.org/abstracts/131151/environmental-study-on-urban-disinfection-using-an-on-site-generation-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131151.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">117</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">36</span> Seasons and Saproxylic Beetles Biodiversity in an Urban Park in Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zina%20Nasr">Zina Nasr</a>, <a href="https://publications.waset.org/abstracts/search?q=Faiek%20Errouissi"> Faiek Errouissi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forest ecosystems are known for its ability to contain a large diversity of fauna especially insects that represent a huge taxonomic group. A portion of forest insects are recognized as saproxylic including the group of organisms that ‘depend on dead or dying wood’ about them, 20% are beetles. We focused our study on saproxylic beetles in an old urban park ‘the park of Belvedere’, located in the north west of Tunis (36° 49'21’ N 10°10'24’ W). The vegetation is dominated by old trees (Eucalyptus, Olea, Aberia, Pinus) and many fallen wood exist. Saproxylic beetles were collected using three interception traps set in the park over one year (from June 2014 to May 2015) and recovered monthly. In total, we collected 189 beetles belonging to 20 families and 57 species. Several saproxylic families (Bostrichidae, Cerambycidae, Curculionidae, Melyridae, Nitidulidae, Staphylinidae), and well known genus (Rhizopertha, Thrychoplerus, Otiorhychus, Dolichosoma, Epuraea, Anotylus) are recorded. We have retained the largest activity of beetles in spring and a very low richness in winter with zero insect per traps. This result was certainly caused by the variation of meteorological factors that mainly influenced the activity of these organisms. Therefore, we were interested on the saproxylic diversity in an urban ‘forest’, and these results will be more interesting when they are compared in the future with other works from natural forest. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saproxylic%20beetles" title="saproxylic beetles">saproxylic beetles</a>, <a href="https://publications.waset.org/abstracts/search?q=seasons" title=" seasons"> seasons</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20park" title=" urban park"> urban park</a>, <a href="https://publications.waset.org/abstracts/search?q=wood" title=" wood"> wood</a> </p> <a href="https://publications.waset.org/abstracts/67561/seasons-and-saproxylic-beetles-biodiversity-in-an-urban-park-in-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67561.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">344</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">35</span> Role of Arbuscular Mycorrhiza in Heavy Metal Tolerance in Sweet Basil Plants</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aboul-Nasr%20Amal">Aboul-Nasr Amal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabry%20Soraya"> Sabry Soraya</a>, <a href="https://publications.waset.org/abstracts/search?q=Sabra%20Mayada"> Sabra Mayada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of phosphorus amendments and arbuscular mycorrhizal (AM) fungi Glomus intraradices on the sweet basil (Ocimum basilicum L.), chemical composition and percent of volatile oil, and metal accumulation in plants and its availability in soil were investigated in field experiment at two seasons 2012 and 2013 under contaminated soil with Pb and Cu. The content of essential oil and shoot and root dry weights of sweet basil was increased by the application of mineral phosphorus as compared to control. Inoculation with AM fungi reduced the metal concentration in shoot, recording a lowest value of (33.24, 18.60 mg/kg) compared to the control (46.49, 23.46 mg/kg) for Pb and Cu, respectively. Availability of Pb and Cu in soil were decreased after cultivation in all treatments compared to control. However, metal root concentration increased with the inoculation, with highest values of (30.15, 39.25 mg/kg)compared to control (22.01, 33.57mg/kg) for Pb and Cu, respectively. The content of linalool and methyl chavicol in basil oil was significantly increased in all treatments compared to control. We can thus conclude that the AM-sweet basil symbiosis could be employed as an approach to bioremediate polluted soils and enhance the yield and maintain the quality of volatile oil of sweet basil plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arbuscular%20mycorrhizal%20fungus" title="arbuscular mycorrhizal fungus">arbuscular mycorrhizal fungus</a>, <a href="https://publications.waset.org/abstracts/search?q=heavy%20metals" title=" heavy metals"> heavy metals</a>, <a href="https://publications.waset.org/abstracts/search?q=sweet%20basil" title=" sweet basil"> sweet basil</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20composition" title=" oil composition"> oil composition</a> </p> <a href="https://publications.waset.org/abstracts/71861/role-of-arbuscular-mycorrhiza-in-heavy-metal-tolerance-in-sweet-basil-plants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71861.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">252</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">34</span> Effect of Thinning Practice on Carbon Storage in Soil Forest Northern Tunisia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zouhaier%20Nasr">Zouhaier Nasr</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Nouri"> Mohamed Nouri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increase in greenhouse gases since the pre-industrial period is a real threat to disrupting the balance of marine and terrestrial ecosystems. Along with the oceans, forest soils are considered to be the planet's second-largest carbon sink. North African forests have been subject to alarming degradation for several decades. The objective of this investigation is to determine and quantify the effect of thinning practiced in pine forests in northern Tunisia on the storage of organic carbon in the trees and in the soil. The plot planted in 1989 underwent thinning in 2005 on to plots; the density is therefore 1600 trees/ha in control and 400 trees/ha in thinning. Direct dendrometric measurements (diameter, height, branches, stem) were taken. In the soil part, six profiles of 1m / 1m / 1m were used for soil and root samples and biomass and organic matter measurements. The measurements obtained were statistically processed by appropriate software. The results clearly indicate that thinning improves tree growth, so the diameter increased from 24.3 cm to 30.1 cm. Carbon storage in the trunks was 35% more and 25% for the whole tree. At ground level, the thinned plot shows a slight increase in soil organic matter and quantity of carbon per tree, exceeding the control by 10 to 25%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forest" title="forest">forest</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon" title=" carbon"> carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=Tunisia" title=" Tunisia"> Tunisia</a> </p> <a href="https://publications.waset.org/abstracts/146020/effect-of-thinning-practice-on-carbon-storage-in-soil-forest-northern-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146020.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">130</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">33</span> Gas Lift Optimization Using Smart Gas Lift Valve</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20A.%20G.%20H.%20Abdalsadig">Mohamed A.

Presently, petroleum industry is investing in exploration and development fields in offshore locations where oil and gas wells are being drilled thousands of feet below the ocean in high pressure and temperature conditions. Therefore, gas-lifted oil wells are capable of failure through gas lift valves which are considered as the heart of the gas lift system for controlling the amount of the gas inside the tubing string. The gas injection rate through gas lift valve must be controlled to be sufficient to obtain and maintain critical flow, also, gas lift valves must be designed not only to allow gas passage through it and prevent oil passage, but also for gas injection into wells to be started and stopped when needed. In this paper, smart gas lift valve has been used to investigate the effect of the valve port size, depth of injection and vertical lift performance on well productivity; all these aspects have been investigated using PROSPER simulator program coupled with experimental data. The results show that by using smart gas lift valve, the gas injection rate can be controlled which leads to improved flow performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Effect%20of%20gas%20lift%20valve%20port%20size" title="Effect of gas lift valve port size">Effect of gas lift valve port size</a>, <a href="https://publications.waset.org/abstracts/search?q=effect%20water%20cut" title=" effect water cut"> effect water cut</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20flow%20performance" title=" vertical flow performance"> vertical flow performance</a> </p> <a href="https://publications.waset.org/abstracts/48540/gas-lift-optimization-using-smart-gas-lift-valve" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48540.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">291</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">32</span> Utilization of Fins to Improve the Response of Pile under Torsional Loads</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Waseim%20Ragab%20Azzam%20Ahmed%20Mohamed%20Nasr">Waseim Ragab Azzam Ahmed Mohamed Nasr</a>, <a href="https://publications.waset.org/abstracts/search?q=Aalaa%20Ibrahim%20Khater"> Aalaa Ibrahim Khater</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Torsional loads from offshore wind turbines, waves, wind, earthquakes, ship collisions in the maritime environment, and electrical transmission towers might affect the pile foundations. Torsional loads can also be caused by the axial load from the sustaining structures. The paper introduces the finned pile, an alternative method of pile modification. The effects of torsional loads were investigated through a series of experimental tests aimed at improving the torsional capacity of a single pile in the sand (where sand was utilized in a state of medium density (Dr = 50%), with or without fins. In these tests, the fins' length, width, form, and number were varied to see how these attributes affected the maximum torsional capacity of the piles. We have noticed the torsion-rotation reaction. The findings demonstrated that the fins improve the maximum torsional capacity of the piles. It was demonstrated that a length of 0.6 times the embedded pile's length and a width equivalent to the pile's diameter constitute the optimal fin geometry. For the conventional pile and the finned pile, the maximum torsional capacities were determined to be 4.12 N.m. and 7.36 N.m., respectively. When subjected to torsional loads, the fins' presence enhanced the piles' maximum torsional capacity by almost 79%. <p class="card-text"><strong>Keywords:</strong> <a
