A big part of this captured CO2 stream is transported at high pressure dense phase conditions and stored in offshore underground depleted oil and gas fields. CO2 is also transported in offshore pipelines to be used for enhanced oil and gas recovery. The captured CO2 stream with impurities may contain water that causes severe corrosion problems, flow assurance failure and might damage valves and instrumentations. Thus, free water formation should be strictly prevented. The purpose of this work is to study the solubility of water in pure CO2 and in CO2 mixtures under real pipeline pressure (90-150 bar) and temperature operation conditions (5-35°C). A set up was constructed to generate experimental data. The results show the solubility of water in CO2 mixtures increasing with the increase of the temperature or/and with the increase in pressure. A drop in water solubility in CO2 is observed in the presence of impurities. The data generated were then used to assess the capabilities of two mixture models: the GERG-2008 model and the EOS-CG model. By generating the solubility data, this study contributes to determine the maximum allowable water content in CO2 pipelines. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture%20and%20storage" title="carbon capture and storage">carbon capture and storage</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20solubility" title=" water solubility"> water solubility</a>, <a href="https://publications.waset.org/abstracts/search?q=equation%20of%20states" title=" equation of states"> equation of states</a>, <a href="https://publications.waset.org/abstracts/search?q=fluids%20engineering" title=" fluids engineering"> fluids engineering</a> </p> <a href="https://publications.waset.org/abstracts/3161/solubility-of-water-in-co2-mixtures-at-pipeline-operation-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3161.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">302</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> Some Metal Levels in Muscle Tissue of Seven Fish Species from the Suğla and Beyşehir Lakes, Turkey</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haluk%20%C3%96zparlak">Haluk Özparlak</a>, <a href="https://publications.waset.org/abstracts/search?q=Murad%20Ayd%C4%B1n%20%C5%9Eanda"> Murad Aydın Şanda</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%BCl%C5%9Fin%20Arslan"> Gülşin Arslan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phoxinellus anatolicus, Carassius gibelio, Sander lucioperca, Vimba vimba tenella, Capoeta capoeta, Tinca tinca from Suğla Lake (Turkey) and Phoxinellus anatolicus, Scardinius erythrophthalmus, Tinca tinca from Beyşehir Lake (Turkey) are economically important fish species and these fish have been consumed as food by local people. P. anatolicus is also endangered and endemic species from Turkey. In this study, concentrations of Cd, Co, Cr, Fe, Mn, Ni, Pb and Zn were determined in muscle tissue of these fish by using atomic absorption spectrophotometer. Levels of metals in the muscle tissue of all the fish specimens were compared with results of previous studies, the tolerance levels of national and international guidelines and the levels of Provisional Tolerable Weekly Intake (PTWI) limits set by FAO/WHO. Concentrations of Cd, Cr, Ni and Pb in the muscle tissue of all the fish specimens from Suğla and Beyşehir Lakes exceeded the tolerance levels of national and international guidelines. However, concentrations of Cd, Fe, Pb and Zn were below PTWI limits. Therefore, in terms of these metal levels, consumption of fresh filet of examined seven fish species (weekly up to about 300 g/person) doesn’t seem to be objectionable for human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bey%C5%9Fehir%20Lake" title="Beyşehir Lake">Beyşehir Lake</a>, <a href="https://publications.waset.org/abstracts/search?q=fish" title=" fish"> fish</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20levels" title=" metal levels"> metal levels</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%C4%9Fla%20Lake" title=" Suğla Lake"> Suğla Lake</a> </p> <a href="https://publications.waset.org/abstracts/29001/some-metal-levels-in-muscle-tissue-of-seven-fish-species-from-the-sugla-and-beysehir-lakes-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29001.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">335</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">6</span> Observations on the Eastern Red Sea Elasmobranchs: Data on Their Distribution and Ecology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Frappi%20Sofia">Frappi Sofia</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicolas%20Pilcher"> Nicolas Pilcher</a>, <a href="https://publications.waset.org/abstracts/search?q=Sander%20DenHaring"> Sander DenHaring</a>, <a href="https://publications.waset.org/abstracts/search?q=Royale%20Hardenstine"> Royale Hardenstine</a>, <a href="https://publications.waset.org/abstracts/search?q=Luis%20Silva"> Luis Silva</a>, <a href="https://publications.waset.org/abstracts/search?q=Collin%20Williams"> Collin Williams</a>, <a href="https://publications.waset.org/abstracts/search?q=Mattie%20Rodrigue"> Mattie Rodrigue</a>, <a href="https://publications.waset.org/abstracts/search?q=Vincent%20Pieriborne"> Vincent Pieriborne</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Qurban"> Mohammed Qurban</a>, <a href="https://publications.waset.org/abstracts/search?q=Carlos%20M.%20Duarte"> Carlos M. Duarte</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, elasmobranch populations are disappearing at a dangerous rate, mainly due to overexploitation, extensive fisheries, as well as climate change. The decline of these species can trigger a cascade effect, which may eventually lead to detrimental impacts on local ecosystems. The Elasmobranch in the Red Sea is facing one of the highest risks of extinction, mainly due to unregulated fisheries activities. Thus, it is of paramount importance to assess their current distribution and unveil their environmental preferences in order to improve conservation measures. Important data have been collected throughout the whole red Sea during the Red Sea Decade Expedition (RSDE) to achieve this goal. Elasmobranch sightings were gathered through the use of submarines, remotely operated underwater vehicles (ROV), scuba diving operations, and helicopter surveys. Over a period of 5 months, we collected 891 sightings, 52 with submarines, 138 with the ROV, 67 with the scuba diving teams, and 634 from helicopters. In total, we observed 657 and 234 individuals from the superorder Batoidea and Selachimorpha, respectively. The most common shark encountered was Iago omanensis, a deep-water shark of the order Carcharhiniformes. To each sighting, data on temperature, salinity density, and dissolved oxygen were integrated to reveal favorable conditions for each species. Additionally, an extensive literature review on elasmobranch research in the Eastern Red Sea has been carried out in order to obtain more data on local populations and to be able to highlight patterns of their distribution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=distribution" title="distribution">distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=elasmobranchs" title=" elasmobranchs"> elasmobranchs</a>, <a href="https://publications.waset.org/abstracts/search?q=habitat" title=" habitat"> habitat</a>, <a href="https://publications.waset.org/abstracts/search?q=rays" title=" rays"> rays</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20sea" title=" red sea"> red sea</a>, <a href="https://publications.waset.org/abstracts/search?q=sharks" title=" sharks"> sharks</a> </p> <a href="https://publications.waset.org/abstracts/162007/observations-on-the-eastern-red-sea-elasmobranchs-data-on-their-distribution-and-ecology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162007.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">85</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> Lymphomas as Estrogen-Regulated Cancers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20S.%20Hasni">M.

However, most lymphoid malignancies show gender differences in incidence and show prognosis with males being more affected. Furthermore, some epidemiological data indicate a protective role of estrogens against Non-Hodgkin lymphomas. Recent studies have demonstrated estrogen receptor β (ERβ) to be the major ER expressed in normal and malignant cells of lymphoid origin. We have analyzed the effects of estradiol and selective ERα and ERβ agonists on lymphoma growth in culture and in vivo. Treating lymphoma cells with estradiol or ERα selective agonist had minor or no effect on cell growth while selective ERβ agonist treatment showed an antiproliferative effect. When grafting mice with murine T lymphoma cells, male mice developed larger tumors compared to female mice, a difference that was abolished following ovariectomy, demonstrating estrogen-dependent growth in vivo. When subcutaneously grafting lymphoma cells to mice, so far growth of all tested human B lymphoma tumors (Raji and Ramos Burkitt lymphoma, SU.DHL4 (GC) and U2932 (ABC) DLBCL, Granta-519, Maver1 and Z138 MCL cells), were reduced following treatment with ERβ selective agonist (ref. 2 and unpublished). Moreover, the number and size of liver foci of disseminating Raji cells was reduced. We have identified target genes and mechanism that could explain the above effects of ERβ agonists. This included effects on angio and lymphangiogenesis. Now we have further analyzed effects of ERβ agonists on Ibrutinib-sensitive and -insensitive MCL cells in xenograft experiments as well as ERβ expression in primary lymphoma material (DLBCL). Preliminary statistical analysis has been done correlating ERβ expression to other biomarkers and clinical data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lymphomas" title="lymphomas">lymphomas</a>, <a href="https://publications.waset.org/abstracts/search?q=estrogen%20receptors" title=" estrogen receptors"> estrogen receptors</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20foci" title=" liver foci"> liver foci</a> </p> <a href="https://publications.waset.org/abstracts/17116/lymphomas-as-estrogen-regulated-cancers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17116.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">411</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> The Optimization of Sexual Health Resource Information and Services for Persons with Spinal Cord Injury</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nasrin%20Nejatbakhsh">Nasrin Nejatbakhsh</a>, <a href="https://publications.waset.org/abstracts/search?q=Anita%20Kaiser"> Anita Kaiser</a>, <a href="https://publications.waset.org/abstracts/search?q=Sander%20Hitzig"> Sander Hitzig</a>, <a href="https://publications.waset.org/abstracts/search?q=Colleen%20McGillivray"> Colleen McGillivray</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Following spinal cord injury (SCI), many individuals experience anxiety in adjusting to their lives, and its impacts on their sexuality. Research has demonstrated that regaining sexual function is a very high priority for individuals with SCI. Despite this, sexual health is one of the least likely areas of focus in rehabilitating individuals with SCI. There is currently a considerable gap in appropriate education and resources that address sexual health concerns and needs of people with spinal cord injury. Furthermore, the determinants of sexual health in individuals with SCI are poorly understood and thus poorly addressed. The purpose of this study was to improve current practices by informing a service delivery model that rehabilitation centers can adopt for appropriate delivery of their services. Methodology: We utilized qualitative methods in the form of a semi-structured interview containing open-ended questions to assess 1) sexual health concerns, 2) helpful strategies in current resources, 3) unhelpful strategies in current resources, and 4) Barriers to obtaining sexual health information. In addition to the interviews, participants completed surveys to identify socio-demographic factors. Data gathered was coded and evaluated for emerging themes and subthemes through a ‘code-recode’ technique. Results: We have identified several robust themes that are important for SCI sexual health resource development. Through analysis of these themes and their subthemes, several important concepts have emerged that could provide agencies with helpful strategies for providing sexual health resources. Some of the important considerations are that services be; anonymous, accessible, frequent, affordable, mandatory, casual and supported by peers. Implications: By incorporating the perspectives of individuals with SCI, the finding from this study can be used to develop appropriate sexual health services and improve access to information through tailored needs based program development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spinal%20cord%20injury" title="spinal cord injury">spinal cord injury</a>, <a href="https://publications.waset.org/abstracts/search?q=sexual%20health" title=" sexual health"> sexual health</a>, <a href="https://publications.waset.org/abstracts/search?q=determinants%20of%20health" title=" determinants of health"> determinants of health</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20development" title=" resource development"> resource development</a> </p> <a href="https://publications.waset.org/abstracts/58980/the-optimization-of-sexual-health-resource-information-and-services-for-persons-with-spinal-cord-injury" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58980.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">251</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> Qualitative Needs Assessment for Development of a Smart Thumb Prosthetic</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syena%20Moltaji">Syena Moltaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephanie%20Posa"> Stephanie Posa</a>, <a href="https://publications.waset.org/abstracts/search?q=Sander%20Hitzig"> Sander Hitzig</a>, <a href="https://publications.waset.org/abstracts/search?q=Amanda%20Mayo"> Amanda Mayo</a>, <a href="https://publications.waset.org/abstracts/search?q=Heather%20Baltzer"> Heather Baltzer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Purpose: To critically assess deficits following thumb amputation and delineate elements of an ideal thumb prosthesis from the end-user perspective. Methods: This was a qualitative study based on grounded theory. End-user stakeholder groups of thumb amputees and prosthetists were interviewed. Transcripts were reviewed whole first for familiarity. Data coding was then performed by two individual authors. Coded units were grouped by similarity and reviewed to reach a consensus. Codes were then analyzed for emergent themes by each author. A consensus meeting was held with all authors to finalize themes. Results: Three patients with traumatic thumb amputation and eight prosthetists were interviewed. Seven themes emerged. First was the significant impact of losing a thumb, in which codes of functional impact, mental impact, and occupational impact were included. The second theme was the unique nature of each thumb amputee, including goals, readiness for prosthesis, nature of the injury, and insurance. The third emergent theme was cost, surrounding government funding, insurability, and prosthetic pricing. The fourth theme was patient frustration, which included mismatches of prosthetic expectations and realities, activity limitations, and causes of devices abandonment. Themes five and six surrounded the strengths and weaknesses of current prosthetics, respectively. Theme seven was the ideal design for a thumb prosthetic, including abilities, suspension, and materials. Conclusions: Representative data from stakeholders mapped the current status of thumb prosthetics. Preferences for an ideal thumb prosthetic emerged, with suggestions for a simple, durable design. The ability to oppose, grasp and sense pressure was reported as functional priorities. Feasible cost and easy fitting emerged as systemic objectives. This data will be utilized in the development of a sensate thumb prosthetic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=smart%20thumb" title="smart thumb">smart thumb</a>, <a href="https://publications.waset.org/abstracts/search?q=thumb%20prosthetic" title=" thumb prosthetic"> thumb prosthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=sensate%20prosthetic" title=" sensate prosthetic"> sensate prosthetic</a>, <a href="https://publications.waset.org/abstracts/search?q=amputation" title=" amputation"> amputation</a> </p> <a href="https://publications.waset.org/abstracts/148325/qualitative-needs-assessment-for-development-of-a-smart-thumb-prosthetic" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148325.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">119</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> Impact of Material Chemistry and Morphology on Attrition Behavior of Excipients during Blending</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sri%20Sharath%20Kulkarni">Sri Sharath Kulkarni</a>, <a href="https://publications.waset.org/abstracts/search?q=Pauline%20Janssen"> Pauline Janssen</a>, <a href="https://publications.waset.org/abstracts/search?q=Alberto%20Berardi"> Alberto Berardi</a>, <a href="https://publications.waset.org/abstracts/search?q=Bastiaan%20Dickhoff"> Bastiaan Dickhoff</a>, <a href="https://publications.waset.org/abstracts/search?q=Sander%20van%20Gessel"> Sander van Gessel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Blending is a common process in the production of pharmaceutical dosage forms where the high shear is used to obtain a homogenous dosage. The shear required can lead to uncontrolled attrition of excipients and affect API’s. This has an impact on the performance of the formulation as this can alter the structure of the mixture. Therefore, it is important to understand the driving mechanisms for attrition. The aim of this study was to increase the fundamental understanding of the attrition behavior of excipients. Attrition behavior of the excipients was evaluated using a high shear blender (Procept Form-8, Zele, Belgium). Twelve pure excipients are tested, with morphologies varying from crystalline (sieved), granulated to spray dried (round to fibrous). Furthermore, materials include lactose, microcrystalline cellulose (MCC), di-calcium phosphate (DCP), and mannitol. The rotational speed of the blender was set at 1370 rpm to have the highest shear with a Froude (Fr) number 9. Varying blending times of 2-10 min were used. Subsequently, after blending, the excipients were analyzed for changes in particle size distribution (PSD). This was determined (n = 3) by dry laser diffraction (Helos/KR, Sympatec, Germany). Attrition was found to be a surface phenomenon which occurs in the first minutes of the high shear blending process. An increase of blending time above 2 mins showed no change in particle size distribution. Material chemistry was identified as a key driver for differences in the attrition behavior between different excipients. This is mainly related to the proneness to fragmentation, which is known to be higher for materials such as DCP and mannitol compared to lactose and MCC. Secondly, morphology also was identified as a driver of the degree of attrition. Granular products consisting of irregular surfaces showed the highest reduction in particle size. This is due to the weak solid bonds created between the primary particles during the granulation process. Granular DCP and mannitol show a reduction of 80-90% in x10(µm) compared to a 20-30% drop for granular lactose (monohydrate and anhydrous). Apart from the granular lactose, all the remaining morphologies of lactose (spray dried-round, sieved-tomahawk, milled) show little change in particle size. Similar observations have been made for spray-dried fibrous MCC. All these morphologies have little irregular or sharp surfaces and thereby are less prone to fragmentation. Therefore, products containing brittle materials such as mannitol and DCP are more prone to fragmentation when exposed to shear. Granular products with irregular surfaces lead to an increase in attrition. While spherical, crystalline, or fibrous morphologies show reduced impact during high shear blending. These changes in size will affect the functionality attributes of the formulation, such as flow, API homogeneity, tableting, formation of dust, etc. Hence it is important for formulators to fully understand the excipients to make the right choices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attrition" title="attrition">attrition</a>, <a href="https://publications.waset.org/abstracts/search?q=blending" title=" blending"> blending</a>, <a href="https://publications.waset.org/abstracts/search?q=continuous%20manufacturing" title=" continuous manufacturing"> continuous manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=excipients" title=" excipients"> excipients</a>, <a href="https://publications.waset.org/abstracts/search?q=lactose" title=" lactose"> lactose</a>, <a href="https://publications.waset.org/abstracts/search?q=microcrystalline%20cellulose" title=" microcrystalline cellulose"> microcrystalline cellulose</a>, <a href="https://publications.waset.org/abstracts/search?q=shear" title=" shear"> shear</a> </p> <a href="https://publications.waset.org/abstracts/147446/impact-of-material-chemistry-and-morphology-on-attrition-behavior-of-excipients-during-blending" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147446.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">111</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> Potential Benefits and Adaptation of Climate Smart Practices by Small Farmers Under Three-Crop Rice Production System in Vietnam</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Azeem%20Tariq">Azeem Tariq</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephane%20De%20Tourdonnet"> Stephane De Tourdonnet</a>, <a href="https://publications.waset.org/abstracts/search?q=Lars%20Stoumann%20Jensen"> Lars Stoumann Jensen</a>, <a href="https://publications.waset.org/abstracts/search?q=Reiner%20Wassmann"> Reiner Wassmann</a>, <a href="https://publications.waset.org/abstracts/search?q=Bjoern%20Ole%20Sander"> Bjoern Ole Sander</a>, <a href="https://publications.waset.org/abstracts/search?q=Quynh%20Duong%20Vu"> Quynh Duong Vu</a>, <a href="https://publications.waset.org/abstracts/search?q=Trinh%20Van%20Mai"> Trinh Van Mai</a>, <a href="https://publications.waset.org/abstracts/search?q=Andreas%20De%20Neergaard"> Andreas De Neergaard</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rice growing area is increasing to meet the food demand of increasing population. Mostly, rice is growing on lowland, small landholder fields in most part of the world, which is one of the major sources of greenhouse gases (GHG) emissions from agriculture fields. The strategies such as, altering water and residues (carbon) management practices are assumed to be essential to mitigate the GHG emissions from flooded rice system. The actual implementation and potential of these measures on small farmer fields is still challenging. A field study was conducted on red river delta in Northern Vietnam to identify the potential challenges and barriers to the small rice farmers for implementation of climate smart rice practices. The objective of this study was to develop and access the feasibility of climate smart rice prototypes under actual farmer conditions. Field and scientific oriented framework was used to meet our objective. The methodological framework composed of six steps: i) identification of stakeholders and possible options, ii) assessment of barrios, drawbacks/advantages of new technologies, iii) prototype design, iv) assessment of mitigation potential of each prototype, v) scenario building and vi) scenario assessment. A farm survey was conducted to identify the existing farm practices and major constraints of small rice farmers. We proposed the two water (pre transplant+midseason drainage and early+midseason drainage) and one straw (full residue incorporation) management option keeping in views the farmers constraints and barriers for implementation. To test new typologies with existing prototypes (midseason drainage, partial residue incorporation) at farmer local conditions, a participatory field experiment was conducted for two consecutive rice seasons at farmer fields. Following the results of each season a workshop was conducted with stakeholders (farmers, village leaders, cooperatives, irrigation staff, extensionists, agricultural officers) at local and district level to get feedbacks on new tested prototypes and to develop possible scenarios for climate smart rice production practices. The farm analysis survey showed that non-availability of cheap labor and lacks of alternatives for straw management influence the small farmers to burn the residues in the fields except to use for composting or other purposes. Our field results revealed that application of early season drainage significantly mitigates (40-60%) the methane emissions from residue incorporation. Early season drainage was more efficient and easy to control under cooperate manage system than individually managed water system, and it leads to both economic (9-11% high rice yield, low cost of production, reduced nutrient loses) and environmental (mitigate methane emissions) benefits. The participatory field study allows the assessment of adaptation potential and possible benefits of climate smart practices on small farmer fields. If farmers have no other residue management option, full residue incorporation with early plus midseason drainage is adaptable and beneficial (both environmentally and economically) management option for small rice farmers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptation" title="adaptation">adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20smart%20agriculture" title=" climate smart agriculture"> climate smart agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=constrainsts" title=" constrainsts"> constrainsts</a>, <a href="https://publications.waset.org/abstracts/search?q=smallholders" title=" smallholders"> smallholders</a> </p> <a href="https://publications.waset.org/abstracts/56419/potential-benefits-and-adaptation-of-climate-smart-practices-by-small-farmers-under-three-crop-rice-production-system-in-vietnam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56419.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">266</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);
