Tacit and explicit knowledge are needed to organize in a path, so the organization will be easy to choose which knowledge will be use. There are many challenges to capture knowledge in the organization, such as researcher must know which knowledge has been validated by an expert, how to get tacit knowledge from experts and make it explicit knowledge, and so on. Besides that, the technology will be a reliable tool to help the researcher to capture knowledge. Some paper wrote how ontology in knowledge management can be used for proposed framework to capture and reuse knowledge. Organization has to manage their knowledge, process capture and share will decide their position in the business area. This paper will describe further from literature review about the tool of ontology that will help the organization to capture its knowledge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=knowledge%20capture" title="knowledge capture">knowledge capture</a>, <a href="https://publications.waset.org/abstracts/search?q=ontology" title=" ontology"> ontology</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=organization" title=" organization"> organization</a> </p> <a href="https://publications.waset.org/abstracts/20921/ontology-as-knowledge-capture-tool-in-organizations-a-literature-review" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20921.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">606</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">8460</span> Conduits of Political Corruption and Patronage in South African Government</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sandiso%20Mahlala">Sandiso Mahlala</a>, <a href="https://publications.waset.org/abstracts/search?q=Fulufhelo%20Netswera"> Fulufhelo Netswera</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anecdotes of corruption and clear-cut lines of patronage in political parties and the government are frequently featured in South African newspapers and news media. Such graft and favouritism have institutionalised themselves more and more, resulting in the phenomenon of governmental capture and the diversion of Covid-19 relief monies. In order to further their own interests, political elites and those working in the public and private sectors influenced government decisions in this way. This paper presents examples of state capture, Covid-19 corruption, and patronage, as well as how these have a negative impact on broader governance and society at large. The fact that such corruption and patronage are occurring at a time when the South African economy is stagnating is particularly troubling since it implies that more people are getting less and raises concerns about the country's future political stability. This article further examines how party patronage as one method by which political parties exploit the state. The conceptual nature of the study is supported by a survey of the relevant literature from a range of sources, such as government regulations, media excepts, and scholarly works. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=political%20corruption" title="political corruption">political corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20patronage" title=" political patronage"> political patronage</a>, <a href="https://publications.waset.org/abstracts/search?q=patronage" title=" patronage"> patronage</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20capture" title=" state capture"> state capture</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=corruption" title=" corruption"> corruption</a>, <a href="https://publications.waset.org/abstracts/search?q=South%20Africa" title=" South Africa"> South Africa</a> </p> <a href="https://publications.waset.org/abstracts/163057/conduits-of-political-corruption-and-patronage-in-south-african-government" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163057.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">72</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">8459</span> Exergy Analysis and Evaluation of the Different Flowsheeting Configurations for CO₂ Capture Plant Using 2-Amino-2-Methyl-1-Propanol</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ebuwa%20Osagie">Ebuwa Osagie</a>, <a href="https://publications.waset.org/abstracts/search?q=Vasilije%20Manovic"> Vasilije Manovic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Exergy analysis provides the identification of the location, sources of thermodynamic inefficiencies, and magnitude in a thermal system. Thus, both the qualitative and quantitative assessment can be evaluated with exergy, unlike energy which is based on quantitative assessment only. The main purpose of exergy analysis is to identify where exergy is destroyed. Thus, reduction of the exergy destruction and losses associated with the capture plant systems can improve work potential. Furthermore, thermodynamic analysis of different configurations of the process helps to identify opportunities for reducing the steam requirements for each of the configurations. This paper presents steady-state simulation and exergy analysis of the 2-amino-2-methyl-1-propanol (AMP)-based post-combustion capture (PCC) plant. Exergy analysis performed for the AMP-based plant and the different configurations revealed that the rich split with intercooling configuration gave the highest exergy efficiency of 73.6%, while that of the intercooling and the reference AMP-based plant were 57.3% and 55.8% respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=2-amino-2-methyl-1-propanol" title="2-amino-2-methyl-1-propanol">2-amino-2-methyl-1-propanol</a>, <a href="https://publications.waset.org/abstracts/search?q=modelling" title=" modelling"> modelling</a>, <a href="https://publications.waset.org/abstracts/search?q=and%20simulation" title=" and simulation"> and simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=post-combustion%20capture%20plant" title=" post-combustion capture plant"> post-combustion capture plant</a>, <a href="https://publications.waset.org/abstracts/search?q=exergy%20analysis" title=" exergy analysis"> exergy analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=flowsheeting%20configurations" title=" flowsheeting configurations"> flowsheeting configurations</a> </p> <a href="https://publications.waset.org/abstracts/105463/exergy-analysis-and-evaluation-of-the-different-flowsheeting-configurations-for-co2-capture-plant-using-2-amino-2-methyl-1-propanol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105463.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">164</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">8458</span> Integrated Simulation and Optimization for Carbon Capture and Storage System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taekyoon%20Park">Taekyoon Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Seokgoo%20Lee"> Seokgoo Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungho%20Kim"> Sungho Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Ung%20Lee"> Ung Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong%20Min%20Lee"> Jong Min Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chonghun%20Han"> Chonghun Han</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CO2 capture and storage/sequestration (CCS) is a key technology for addressing the global warming issue.

Some of the major application areas that have been rapidly evolving include the advanced human interfaces, virtual reality and security/surveillance systems. This study provides a brief overview of the techniques and applications used for the markerless human motion capture, which deals with analyzing the human motion in the form of mathematical formulations. The major contribution of this research is that it classifies the computer vision based techniques of human motion capture based on the taxonomy, and then breaks its down into four systematically different categories of tracking, initialization, pose estimation and recognition. The detailed descriptions and the relationships descriptions are given for the techniques of tracking and pose estimation. The subcategories of each process are further described. Various hypotheses have been used by the researchers in this domain are surveyed and the evolution of these techniques have been explained. It has been concluded in the survey that most researchers have focused on using the mathematical body models for the markerless motion capture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20motion%20capture" title="human motion capture">human motion capture</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20vision" title=" computer vision"> computer vision</a>, <a href="https://publications.waset.org/abstracts/search?q=vision-based" title=" vision-based"> vision-based</a>, <a href="https://publications.waset.org/abstracts/search?q=tracking" title=" tracking"> tracking</a> </p> <a href="https://publications.waset.org/abstracts/22770/human-motion-capture-new-innovations-in-the-field-of-computer-vision" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22770.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">319</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">8456</span> Enhancement of CO2 Capture by Using Cu-Nano-Zeolite Synthesized</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pham-Thi%20Huong">Pham-Thi Huong</a>, <a href="https://publications.waset.org/abstracts/search?q=Byeong-Kyu%20Lee"> Byeong-Kyu Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Chi-Hyeon%20Lee"> Chi-Hyeon Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jitae%20Kim"> Jitae Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study synthesized Cu-nano-zeolite was evaluated for its potential use in CO2 capture. The specific surface area of Cu-nano zeolite was measured as 869.32 m2/g with a pore size of 3.86 nm. The adsorption capacity of CO2 by Cu-nano zeolite was decreased with increasing temperature. The identified adsorption capacity of CO2 by Cu-nano zeolite was 7.16 mmol/g at a temperature of 20 oC and at pressure of 1 atm. The adoption selectivity of CO2 over N2 strongly depend on the temperature and the highest selectivity by Cu-nano zeolite was 50.71 at 20 oC. From analysis of regeneration characteristics of CO2 loaded adsorbent, the percentage removal of CO2 was maintained at more than 78.2 % even after 10 cycles of adsorption-desorption. Based on these result, the Cu-nano zeolite can be used as an effective and economical adsorbent for CO2 capture. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO2%20capture" title="CO2 capture">CO2 capture</a>, <a href="https://publications.waset.org/abstracts/search?q=selectivity" title=" selectivity"> selectivity</a>, <a href="https://publications.waset.org/abstracts/search?q=Cu-nano%20zeolite" title=" Cu-nano zeolite"> Cu-nano zeolite</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration." title=" regeneration.

This research targets to continuously capture the low concentration CO₂ from the tail gas of the regenerative thermal oxidizer (RTO) in the high technology industry. A rotating packed bed (RPB) reactor is investigated to capture the efficiency of CO₂ using a mixture of NaOH/Na₂CO₃ solutions to simulate the real absorbed solution. On a lab scale, semi-batch experiments of continuous gas flow and circulating absorbent solution are conducted to find the optimal parameters and are then examined in a continuous operation. In the semi-batch tests, the carbon capture efficiency and pH variation in the conditions of a low concentration CO₂ (about 1.13 vol%), the NaOH concentration of 1 wt% or 2 wt% mixed with 14 wt% Na₂CO₃, the rotating speed (600, 900, 1200 rpm), the gas-liquid ratio (100, 200, and 400), and the temperature of absorbent solution of 40 ºC are studied. The CO₂ capture efficiency significantly increases with higher rotating speed and smaller gas-liquid ratio, respectively, while the difference between the NaOH concentration of 1 wt% and 2 wt% is relatively small. The maximum capture efficiency is close to 80% in the conditions of the NaOH concentration of 1 wt%, the G/L ratio of 100, and the rotating speed of 1200 rpm within the first 5 minutes. Furthermore, the continuous operation based on similar conditions also demonstrates the steady efficiency of the carbon capture of around 80%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20capture" title="carbon dioxide capture">carbon dioxide capture</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerative%20thermal%20oxidizer" title=" regenerative thermal oxidizer"> regenerative thermal oxidizer</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20packed%20bed" title=" rotating packed bed"> rotating packed bed</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20hydroxide" title=" sodium hydroxide"> sodium hydroxide</a> </p> <a href="https://publications.waset.org/abstracts/182235/an-experimental-study-of-low-concentration-co2-capture-from-regenerative-thermal-oxidation-tail-gas-in-rotating-packed-bed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182235.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">61</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">8454</span> Ionic Liquids as Corrosion Inhibitors in CO2 Capture Systems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Acidi">A.

A single column Temperature /Vacuum Swing Adsorption (TSA/VSA) process is proposed as an alternative option to multi column Pressure Swing Adsorption (PSA) processes. The proposed adsorbent is SIFSIX-3-Ni, a newly developed MOF (Metal Organic Framework), with extended CO2 selectivity and capacity. There are three stages involved in this paper: (i) SIFSIX-3-Ni is synthesized and pelletized and its physical and chemical properties are examined before and after the pelletization process, (ii) experiments are designed and undertaken for the estimation of the diffusion and adsorption parameters and limitations for CO2 undergoing capture from the air; and (iii) the CO2 adsorption capacity and dynamical characteristics of SIFSIX-3-Ni are investigated both experimentally and mathematically by employing a single column TSA/VSA, for the capture of atmospheric CO2. This work is further supported by a technical-economical study for the estimation of the investment cost and the energy consumption of the single column TSA/VSA process. The simulations are performed using gProms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20capture" title="carbon dioxide capture">carbon dioxide capture</a>, <a href="https://publications.waset.org/abstracts/search?q=temperature%2Fvacuum%20swing%20adsorption" title=" temperature/vacuum swing adsorption"> temperature/vacuum swing adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=metal%20organic%20frameworks" title=" metal organic frameworks"> metal organic frameworks</a>, <a href="https://publications.waset.org/abstracts/search?q=SIFSIX-3-Ni" title=" SIFSIX-3-Ni"> SIFSIX-3-Ni</a> </p> <a href="https://publications.waset.org/abstracts/57076/atmospheric-co2-capture-via-temperaturevacuum-swing-adsorption-in-sifsix-3-ni" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57076.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">263</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">8452</span> Classification of State Transition by Using a Microwave Doppler Sensor for Wandering Detection </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Shiba">K.

And PwDs may wander and unconsciously set foot outdoors, it may lead serious accidents, such as, traffic accidents. Here, round-the-clock monitoring by caregivers is necessary, which can be a burden for the caregivers. Therefore, an automatic wandering detection system is required when an elderly person wanders outdoors, in which case the detection system transmits a ‘moving’ followed by an ‘absence’ state. In this paper, we focus on the transition from the ‘resting’ to the ‘absence’ state, via the ‘moving’ state as one of the wandering transitions. To capture the transition of the three states, our method based on the hidden Markov model (HMM) is built. Using our method, the restraint where the ‘resting’ state and ‘absence’ state cannot be transmitted to each other is applied. To validate our method, we conducted the experiment with 10 subjects. Our results show that the method can classify three states with 0.92 accuracy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wander" title="wander">wander</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20Doppler%20sensor" title=" microwave Doppler sensor"> microwave Doppler sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=respiratory%20frequency%20band" title=" respiratory frequency band"> respiratory frequency band</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20state%20transition" title=" the state transition"> the state transition</a>, <a href="https://publications.waset.org/abstracts/search?q=hidden%20Markov%20model%20%28HMM%29." title=" hidden Markov model (HMM)."> hidden Markov model (HMM).</a> </p> <a href="https://publications.waset.org/abstracts/81566/classification-of-state-transition-by-using-a-microwave-doppler-sensor-for-wandering-detection" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81566.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">183</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">8451</span> A Study on the Establishment of a 4-Joint Based Motion Capture System and Data Acquisition</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyeong-Ri%20Ko">Kyeong-Ri Ko</a>, <a href="https://publications.waset.org/abstracts/search?q=Seong%20Bong%20Bae"> Seong Bong Bae</a>, <a href="https://publications.waset.org/abstracts/search?q=Jang%20Sik%20Choi"> Jang Sik Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Sung%20Bum%20Pan"> Sung Bum Pan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A simple method for testing the posture imbalance of the human body is to check for differences in the bilateral shoulder and pelvic height of the target.

Thus, use of fossil fuel is efficient which results in large liberation of carbon dioxide in atmosphere. Tons of this CO2 raises the risk of dangerous climate changes. To minimize the risk carbon capture and storage (CCS) has to be used so that the emitted carbon dioxide do not reach the atmosphere. CCS is being considered as one of the options that could have a major role to play in India.With the growing awareness towards the global warming, carbon capture and sequestration has a great importance. New technologies and theories are in use to capture CO2. This paper contains the methodology and technologies that is in use to capture carbon dioxide in India. The present scenario of CCS is also being discussed. CCS is playing a major role in enhancing recovery of oil (ERO). Both the purpose 1) minimizing percentage of carbon dioxide in atmosphere and 2) enhancing recovery of oil are fulfilled from the CCS. The CO2 is usually captured from coal based power plant and from some industrial sources and then stored in the geological formations like oil and gas reservoir and deep aquifers or in oceans. India has large reservoirs of coal which are being used for storing CO2, as coal is a good absorbent of CO2. New technologies and studies are going on for injection purposes. Government has initiated new plans for CCS as CCS is technically feasible and economically attractive. A discussion is done on new schemes that should bring up CCS plans and approaches. Stakeholders are welcomed for suitability of CCS. There is still a need to potentially capture the CO2 and avail its storage in developing country like India. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carbon%20Capture%20and%20Storage%20%28CCS%29" title="Carbon Capture and Storage (CCS)">Carbon Capture and Storage (CCS)</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20%28CO2%29" title=" carbon dioxide (CO2)"> carbon dioxide (CO2)</a>, <a href="https://publications.waset.org/abstracts/search?q=enhance%20oil%20recovery" title=" enhance oil recovery"> enhance oil recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=geological%20formations" title=" geological formations"> geological formations</a>, <a href="https://publications.waset.org/abstracts/search?q=stakeholders" title=" stakeholders "> stakeholders </a> </p> <a href="https://publications.waset.org/abstracts/17427/carbon-capture-and-storage-prospects-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17427.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">470</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">8449</span> Carbon Dioxide Capture, Utilization, and Storage: Sequestration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Sachan">Ankur Sachan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon dioxide being the most anthropogenic greenhouse gas,it needs to be isolated from entering into atmosphere. Carbon capture and storage is process that captures CO2 emitted from various sources, separates it from other gases and stores it in a safe place preferably in underground geological formations for large period of time. It is then purified and monitored so that can be made to reuse. Monoethanolamine, zeolitic imidazolate framework, microalgae, membranes etc are utilized to capture CO2. Post-combustion, pre-combustion and oxyfuel combustion along with chemical looping combustion are technologies for scrubbing CO2. The properties of CO2 being easily miscible and readily dissolving in oil with impurities makes it capable for numerous applications such as in producing oil by enhanced oil recovery (EOR), Bio CCS Algal Synthesis etc. CO2-EOR operation is capable to produce million barrels of oil and extend the field's lifetime as in case of Weyburn Oil Field in Canada. The physical storage of CO2 is technically the most feasible direction provided that the associated safety and sustainability issues can be met and new materials for CCUS process at low cost are urgently found so that so that fossil based systems with carbon capture are cost competitive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture" title="carbon capture">carbon capture</a>, <a href="https://publications.waset.org/abstracts/search?q=CCUS" title=" CCUS"> CCUS</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=oil" title=" oil "> oil </a> </p> <a href="https://publications.waset.org/abstracts/20310/carbon-dioxide-capture-utilization-and-storage-sequestration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20310.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">519</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">8448</span> Effect of Anion Variation on the CO2 Capture Performance of Pyridinium Containing Poly(ionic liquid)s </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Zulfiqar">Sonia Zulfiqar</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniele%20Mantione"> Daniele Mantione</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Ilyas%20Sarwar"> Muhammad Ilyas Sarwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexander%20Rothenberger"> Alexander Rothenberger</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Mecerreyes"> David Mecerreyes </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change due to escalating carbon dioxide concentration in the atmosphere is an issue of paramount importance that needs immediate attention. CO2 capture and sequestration (CCS) is a promising route to mitigate climate change and adsorption is the most widely recognized technology owing to possible energy savings relative to the conventional absorption techniques. In this conference, the potential of a new family of solid sorbents for CO2 capture and separation will be presented. Novel pyridinium containing poly(ionic liquid)s (PILs) were synthesized with varying anions i.e bis(trifluoromethylsulfonyl)imide and hexafluorophosphate.

For this purpose, two tests were carried out on the weight loss test. And one was analyzed using a carbon dioxide quantification device. First, the ignition loss analysis was performed by measuring the weight of the sample at 550°C after the first conversation and then confirming the loss when ignited at 950°C. Second, in the thermogravimetric analysis, the sample was divided into two sections of 40 to 500°C and 500 to 800°C to confirm the reduction. The results of thermal weight loss analysis and thermogravimetric analysis were confirmed to be almost similar. However, the temperature of the ignition loss analysis method was 950°C, which was 150°C higher than that of the thermogravimetric method at a temperature of 800°C, so that the difference in the amount of weight loss was 3 to 4% higher by the heat loss analysis method. In addition, the tendency that the CO₂ content increases as the reaction time become longer is similarly confirmed. Third, the results of the wet titration method through the carbon dioxide quantification device were found to be significantly lower than the weight loss method. Therefore, based on the results obtained through the above three analysis methods, we will establish a method to analyze the accurate amount of CO₂.

Energy assessment on amine-based post-combustion CCS on LNG-fuelled ships showed that the energy efficiency of CCS ships reduced from 48% to 36.6%. Then, an energy assessment was carried out to compare the power and heat requirements of the most used hydrogen production methods and carbon capture technologies. Steam methane reformer (SMR) was found to be 20% more energy efficient and achieved a higher methane conversion than auto thermal reaction and methane decomposition. Next, pressure swing adsorber (PSA) has shown a lower energy requirement than membrane separation, cryogenic separation, and amine absorption in pre-combustion carbon capture. Hence, an integrated system combining SMR and PSA (SMR-PSA) with waste heat integration (WHR) was proposed. This optimized SMR-based integrated system has achieved 65% of CO₂ reduction with less than 7-percentage point of energy penalty (41.7% of energy efficiency). Further integration of post-combustion CCS with the SMR-PSA integrated system improved carbon capture rate to 86.3% with 9-percentage points of energy penalty (39% energy efficiency). The proposed system was shown to be able to meet the carbon reduction targets set by International Maritime Organization (IMO) with certain energy penalties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shipping" title="shipping">shipping</a>, <a href="https://publications.waset.org/abstracts/search?q=decarbonisation" title=" decarbonisation"> decarbonisation</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20fuels" title=" alternative fuels"> alternative fuels</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20carbon" title=" low carbon"> low carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture" title=" carbon capture"> carbon capture</a> </p> <a href="https://publications.waset.org/abstracts/162788/estimation-of-energy-efficiency-of-blue-hydrogen-production-onboard-of-ships" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162788.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">78</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">8445</span> Carbon Capture: Growth and Development of Membranes in Gas Sequestration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sreevalli%20Bokka">Sreevalli Bokka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various technologies are emerging to capture or reduce carbon intensity from a gas stream, such as industrial effluent air and atmosphere.

The present study evaluates and optimizes CO<sub>2</sub> capture through a process, where carbon dioxide is passed into pH adjusted high salinity water and reacted with sodium chloride to form a precipitate of sodium bicarbonate. This process is based on a modified Solvay process with higher CO<sub>2</sub> capture efficiency, higher sodium removal, and higher pH level without the use of ammonia. The process was tested in a bubble column semi-batch reactor and was optimized using response surface methodology (RSM). CO<sub>2</sub> capture efficiency and sodium removal were optimized in terms of major operating parameters based on four levels and variables in Central Composite Design (CCD). The operating parameters were gas flow rate (0.5–1.5 L/min), reactor temperature (10 to 50 <sup>o</sup>C), buffer concentration (0.2-2.6%) and water salinity (25-197 g NaCl/L). The experimental data were fitted to a second-order polynomial using multiple regression and analyzed using analysis of variance (ANOVA). The optimum values of the selected variables were obtained using response optimizer. The optimum conditions were tested experimentally using desalination reject brine with salinity ranging from 65,000 to 75,000 mg/L. The CO<sub>2</sub> capture efficiency in 180 min was 99% and the maximum sodium removal was 35%. The experimental and predicted values were within 95% confidence interval, which demonstrates that the developed model can successfully predict the capture efficiency and sodium removal using the modified Solvay method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO2%20capture" title="CO2 capture">CO2 capture</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20desalination" title=" water desalination"> water desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=Response%20Surface%20Methodology" title=" Response Surface Methodology"> Response Surface Methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=bubble%20column%20reactor" title=" bubble column reactor"> bubble column reactor</a> </p> <a href="https://publications.waset.org/abstracts/45373/statistical-analysis-and-optimization-of-a-process-for-co2-capture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45373.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">287</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">8443</span> Rethinking International Relations Theory through the Lens of Outside-in Logic of State-Building</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nana%20Kwasi%20Amoateng">Nana Kwasi Amoateng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper uses secondary information to investigate some longstanding limitations in International Relations (IR) theory. Specifically, the analysis highlights IR theory through the lens of J. C. Sharman’s brilliant concept of outside-in state-building logic in which some states, particularly those in Africa, have relied mainly on foreign resources to address local threats. The key findings are that IR theory has been largely understood from the perspective of an inside-out state-building logic, whereby Western and other advanced states have heavily relied on local resources to address foreign threats. In this vein, IR theorists, including Critical Theorists, have not been able to fully grasp African states and states elsewhere that have generally relied on an outside-in logic of state-building. The paper helps to fill a major gap in IR theory, which has mainly addressed criticisms of being Euro- or Western-centric or failing to include the unique experiences of states and other actors in the Global South by developing critical theories such as post-colonial theory and neo-colonialism. Although this has helped to understand some experiences of actors in the Global South, the fundamental difference between state-building in the West and the Global South, particularly Africa, has not been adequately explored to fully comprehend why, despite the works of Critical Theorists, IR theory still fails to capture many political and socioeconomic realities in Africa and elsewhere. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=international%20relations%20theory" title="international relations theory">international relations theory</a>, <a href="https://publications.waset.org/abstracts/search?q=outside-in%20state-building%20logic" title=" outside-in state-building logic"> outside-in state-building logic</a>, <a href="https://publications.waset.org/abstracts/search?q=inside-out%20state-building%20logic" title=" inside-out state-building logic"> inside-out state-building logic</a>, <a href="https://publications.waset.org/abstracts/search?q=Africa" title=" Africa"> Africa</a> </p> <a href="https://publications.waset.org/abstracts/181454/rethinking-international-relations-theory-through-the-lens-of-outside-in-logic-of-state-building" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181454.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">84</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">8442</span> Design, Development and Evaluation of a Portable Recording System to Capture Dynamic Presentations using the Teacher´s Tablet PC</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Enrique%20Barra">Enrique Barra</a>, <a href="https://publications.waset.org/abstracts/search?q=Abel%20Carril"> Abel Carril</a>, <a href="https://publications.waset.org/abstracts/search?q=Aldo%20Gordillo"> Aldo Gordillo</a>, <a href="https://publications.waset.org/abstracts/search?q=Joaquin%20Salvachua"> Joaquin Salvachua</a>, <a href="https://publications.waset.org/abstracts/search?q=Juan%20Quemada"> Juan Quemada</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Computers and multimedia equipment have improved a lot in the last years.

An average value of 1.83 tons of CO₂ is emitted for every ton of steel produced, resulting in over 3.3 Mt of CO₂ emissions each year. The present paper is focused on the investigation and comparison of two O₂ separation methods and two CO₂ capture technologies applicable to iron and steel industry. The O₂ used in steel production comes from an Air Separation Unit (ASU) using distillation or from air separation using membranes. The CO₂ capture technologies are represented by a two-stage membrane separation process and the gas-liquid absorption using methyl di-ethanol amine (MDEA). Process modelling and simulation tools, as well as environmental tools, are used in the present study. The production capacity of the steel mill is 4,000,000 tones/year. In order to compare the two CO₂ capture technologies in terms of efficiency, performance, and sustainability, the following cases have been investigated: Case 1: steel production using O₂ from ASU and no CO₂ capture; Case 2: steel production using O₂ from ASU and gas-liquid absorption for CO₂ capture; Case 3: steel production using O₂ from ASU and membranes for CO₂ capture; Case 4: steel production using O₂ from membrane separation method and gas-liquid absorption for CO₂ capture and Case-5: steel production using membranes for air separation and CO₂ capture. The O₂ separation rate obtained in the distillation technology was about 96%, and about 33% in the membrane technology. Similarly, the O₂ purity resulting in the conventional process (i.e. distillation) is higher compared to the O₂ purity obtained in the membrane unit (e.g., 99.50% vs. 73.66%). The air flow-rate required for membrane separation is about three times higher compared to the air flow-rate for cryogenic distillation (e.g., 549,096.93 kg/h vs. 189,743.82 kg/h). A CO₂ capture rate of 93.97% was obtained in the membrane case, while the CO₂ capture rate for the gas-liquid absorption was 89.97%. A quantity of 6,626.49 kg/h CO₂ with a purity of 95.45% is separated from the total 23,352.83 kg/h flue-gas in the membrane process, while with absorption of 6,173.94 kg/h CO₂ with a purity of 98.79% is obtained from 21,902.04 kg/h flue-gas and 156,041.80 kg/h MDEA is recycled. The simulation results, performed using ChemCAD process simulator software, lead to the conclusion that membrane-based technology can be a suitable alternative for CO₂ removal for steel production. An environmental evaluation using Life Cycle Assessment (LCA) methodology was also performed. Considering the electricity consumption, the performance, and environmental indicators, Case 3 can be considered the most effective. The environmental evaluation, performed using GaBi software, shows that membrane technology can lead to lower environmental emissions if membrane production is based on benzene derived from toluene hydrodealkilation and chlorine and sodium hydroxide are produced using mixed technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20capture" title="CO₂ capture">CO₂ capture</a>, <a href="https://publications.waset.org/abstracts/search?q=gas-liquid%20absorption" title=" gas-liquid absorption"> gas-liquid absorption</a>, <a href="https://publications.waset.org/abstracts/search?q=Life%20Cycle%20Assessment" title=" Life Cycle Assessment"> Life Cycle Assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=membrane%20separation" title=" membrane separation"> membrane separation</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20production" title=" steel production"> steel production</a> </p> <a href="https://publications.waset.org/abstracts/139411/co2-capture-by-membrane-applied-to-steel-production-process" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139411.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">8439</span> A DNA-Based Nano-biosensor for the Rapid Detection of the Dengue Virus in Mosquito </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lilia%20M.%20Fernando">Lilia M.

The biosensor detection encompasses two sets of oligonucleotide probes that are specific to the dengue virus: the detector probe labeled with the EAM nanoparticles and the biotinylated capture probe. The DNA targets are double hybridized to the detector and the capture probes and concentrated from nonspecific DNA fragments by applying a magnetic field. Subsequently, the DNA sandwiched targets (EAM-detector probe–DNA target–capture probe-biotin) are captured on streptavidin modified screen printed carbon electrodes through the biotinylated capture probes. Detection is achieved electrochemically by measuring the oxidation–reduction signal of the EAM nanoparticles. Results indicate that the biosensor is able to detect the redox signal of the EAM nanoparticles at dengue DNA concentrations as low as 10 ng/ul. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dengue" title="dengue">dengue</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20nanoparticles" title=" magnetic nanoparticles"> magnetic nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=mosquito" title=" mosquito"> mosquito</a>, <a href="https://publications.waset.org/abstracts/search?q=nanobiosensor" title=" nanobiosensor"> nanobiosensor</a> </p> <a href="https://publications.waset.org/abstracts/37690/a-dna-based-nano-biosensor-for-the-rapid-detection-of-the-dengue-virus-in-mosquito" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/37690.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">366</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">8438</span> Sampling Error and Its Implication for Capture Fisheries Management in Ghana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temiloluwa%20J.%20Akinyemi">Temiloluwa J.

However, the misperception of biophysical dynamics owing to a lack of adequate scientific data has contributed to the suboptimal management in marine capture fisheries. This is because yield and catch potentials are sensitive to the quality of catch and effort data. Yet, studies on fisheries data collection practices in developing countries are hard to find. This study investigates the data collection methods utilized by fisheries technical officers within the four fishing regions of Ghana. We found that the officers employed data collection and sampling procedures which were not consistent with the technical guidelines curated by FAO. For example, 50 instead of 166 landing sites were sampled, while 290 instead of 372 canoes were sampled. We argue that such sampling errors could result in the over-capitalization of capture fish stocks and significant losses in resource rents. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fisheries%20data%20quality" title="Fisheries data quality">Fisheries data quality</a>, <a href="https://publications.waset.org/abstracts/search?q=fisheries%20management" title=" fisheries management"> fisheries management</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghana" title=" Ghana"> Ghana</a>, <a href="https://publications.waset.org/abstracts/search?q=Sustainable%20Fisheries" title=" Sustainable Fisheries"> Sustainable Fisheries</a> </p> <a href="https://publications.waset.org/abstracts/161493/sampling-error-and-its-implication-for-capture-fisheries-management-in-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161493.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">92</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">8437</span> Electrospinning Preparation of Superhydrophobic Polydimethylsiloxane/Polystyrene Nanofibrous Membranes for Carbon Dioxide Capture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chia-Yu%20Chang">Chia-Yu Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yi-Feng%20Lin"> Yi-Feng Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CO2 capture has attracted significant research attention due to global warming. Among the various CO2 capture methods, membrane technology has proven to be highly efficient in capturing CO2 due to the ease at which this technology can be scaled up, its low energy consumptions, small area requirements and overall environmental friendliness for use by industrial plants. Capturing CO2 is to use a membrane contactor with a combination of water-repellent porous membranes and chemical absorption processes. In a CO2 membrane contactor system, CO2 passes through a hydrophobic porous membrane in the gas phase to contact the amine absorbent in the liquid phase. Consequently, additional CO2 gas is absorbed by amine absorbents. This study examines highly porous Polydimethylsiloxane (PDMS)/Polystyrene (PS) Nanofibrous Membranes and successfully coated onto a macroporous Al2O3 membrane. The performance of these materials in a membrane contactor system for CO2 absorption is also investigated. Compared with pristine PS nanofibrous membranes, the PDMS/PS nanofibrous membranes exhibit greater solvent resistance and mechanical strength, making them more suitable for use in CO2 capture by the membrane contactor. The resulting hydrophobic membrane contactor also demonstrates the potential for large-scale CO2 absorption during post-combustion processes in power plants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO2%20capture" title="CO2 capture">CO2 capture</a>, <a href="https://publications.waset.org/abstracts/search?q=polystyrene" title=" polystyrene"> polystyrene</a>, <a href="https://publications.waset.org/abstracts/search?q=polydimethylsiloxane" title=" polydimethylsiloxane"> polydimethylsiloxane</a>, <a href="https://publications.waset.org/abstracts/search?q=superhydrophobic" title=" superhydrophobic"> superhydrophobic</a> </p> <a href="https://publications.waset.org/abstracts/21442/electrospinning-preparation-of-superhydrophobic-polydimethylsiloxanepolystyrene-nanofibrous-membranes-for-carbon-dioxide-capture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21442.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">388</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">8436</span> The Environmental Effects of the Flood Disaster in Anambra State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=U.%20V.%20Okpala">U.

In developing countries it occurs as a result of blocking of natural and man-made drainages and poor maintenance of water dams/reservoirs which seldom give way after persistent heavy down pours. In coastal lowlands and swamp lands, flooding is aided mainly by blocked channels and indiscriminate sand fling of coastal swamp areas and natural drainage channel for urban development/constructions. In this paper, the causes of flood and possible scientific, technological, political, economic and social impacts of flood disaster on the environment a case study of Anambra State have been studied. Often times flooding is caused by climate change, especially in the developed economy where scientific mitigating options are highly employed. Researchers have identified Green Houses Gases (GHG) as the cause of global climate change. The recent flood disaster in Anambra State which caused physical damage to structures, social dislocation, contamination of clean drinking water, spread of water-borne diseases, shortage of crops and food supplies, death of non-tolerant tree species, disruption in transportation system, serious economic loss and psychological trauma is a function of climate change. There is need to encourage generation of renewable energy sources, use of less carbon intensive fuels and other energy efficient sources. Carbon capture/sequestration, proper management of our drainage systems and good maintenance of our dams are good option towards saving the environment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flooding" title="flooding">flooding</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=carbon%20capture" title=" carbon capture"> carbon capture</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20systems" title=" energy systems"> energy systems</a> </p> <a href="https://publications.waset.org/abstracts/3215/the-environmental-effects-of-the-flood-disaster-in-anambra-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3215.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">375</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">8435</span> Mobilizing Resources for Social Entrepreneurial Opportunity: A Framework of Engagement Strategy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Balram%20Bhushan">Balram Bhushan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The emergence of social entrepreneurship challenges the strict categorization of not-for-profit, for-profit and hybrid organizations. Although the blurring of boundaries helps social entrepreneurial organizations (SEOs) make better use of emerging opportunities, it poses a significant challenge while mobilizing money from different sources. Additionally, for monetary resources, the legal framework of the host country may further complicate the issue by imposing strict accounting standards. Under such circumstances, the resource providers fail to recognize the suitable engagement strategy with the SEO of their choice. Based on the process of value creation and value capture, this paper develops a guiding framework for resource providers to design an appropriate mix of engagement with the identified SEOs. Essentially, social entrepreneurship creates value at the societal level, but value capture is a characteristic of an organization. Additionally, SEOs prefer value creation over value capture. The paper argued that the nature of the relationship between value creation and value capture determines the extent of blurred boundaries of the organization. Accordingly, synergistic, antagonistic and sequential relationships were proposed between value capture and value creation. When value creation is synergistically associated with value creation, the preferred nature of such action falls within the nature of for-profit organizations within the strictest legal framework. Banks offering micro-loans are good examples of this category. Opposite to this, the antagonist relationship between value creation and value capture, where value capture opportunities are sacrificed for value creation, dictates non-profit organizational structure. Examples of this category include non-government organizations and charity organizations. Finally, the sequential relationship between value capture opportunities is followed for value creation opportunities and guides the action closer to the hybrid structure. Examples of this category include organizations where a non-for-profit unit controls for-profit units of the organization either legally or structurally. As an SEO may attempt to utilize multiple entrepreneurial opportunities falling across any of the three relationships between value creation and value capture, the resource providers need to evaluate an appropriate mix of these relationships before designing their engagement strategies. The paper suggests three guiding principles for the engagement strategy. First, the extent of investment should be proportional to the synergistic relationship between value capture and value creation. Second, the subsidized support should be proportional to the sequential relationship. Finally, the funding (charity contribution) should be proportional to the antagonistic relationship. Finally, the resource providers are needed to keep a close watch on the evolving relationship between value creation and value capture for introducing appropriate changes in their engagement strategy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20entrepreneurship" title="social entrepreneurship">social entrepreneurship</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20creation" title=" value creation"> value creation</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20capture" title=" value capture"> value capture</a>, <a href="https://publications.waset.org/abstracts/search?q=entrepreneurial%20opportunity" title=" entrepreneurial opportunity"> entrepreneurial opportunity</a> </p> <a href="https://publications.waset.org/abstracts/148370/mobilizing-resources-for-social-entrepreneurial-opportunity-a-framework-of-engagement-strategy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148370.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">132</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">8434</span> Capture Zone of a Well Field in an Aquifer Bounded by Two Parallel Streams</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Nagheli">S.

The equations can be applied as useful tools to design in-situ groundwater remediation systems, to evaluate the surface–subsurface water interaction and to manage the water resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=complex%20potential" title="complex potential">complex potential</a>, <a href="https://publications.waset.org/abstracts/search?q=conformal%20mapping" title=" conformal mapping"> conformal mapping</a>, <a href="https://publications.waset.org/abstracts/search?q=image%20well%20theory" title=" image well theory"> image well theory</a>, <a href="https://publications.waset.org/abstracts/search?q=Laplace%E2%80%99s%20equation" title=" Laplace’s equation"> Laplace’s equation</a>, <a href="https://publications.waset.org/abstracts/search?q=superposition%20principle" title=" superposition principle"> superposition principle</a> </p> <a href="https://publications.waset.org/abstracts/81814/capture-zone-of-a-well-field-in-an-aquifer-bounded-by-two-parallel-streams" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81814.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">432</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">8433</span> Motion Capture Based Wizard of Oz Technique for Humanoid Robot</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rafal%20Stegierski">Rafal Stegierski</a>, <a href="https://publications.waset.org/abstracts/search?q=Krzysztof%20Dmitruk"> Krzysztof Dmitruk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper focuses on robotic tele-presence system build around humanoid robot operated with controller-less Wizard of Oz technique.

To address this challenge, carbon capture and sequestration (CCS) technology has emerged as a key strategy for selectively capturing CO₂ from flue gas streams. Among the various solid adsorbents, metal–organic frameworks (MOFs) are notable for their extensive surface area and controllable pore chemistry. The porous MOF structure is comprised of metal ions or clusters coordinated to organic linker compounds. In particular, the pore parameters of MOFs are readily tunable, making them promising materials for CO₂ capture applications. Among these, amine-functionalized MOFs have demonstrated exceptional CO₂ capture abilities because their high uptake capacity and selectivity. In this study, we have investigated the CO₂ capture abilities and adsorption mechanisms of the diamine-appended framework N-Ethylethylenediamine-Mg₂(4,4’-dioxidobiphenyl-3,3’-dicarboxylate) (e-2-Mg₂(dobpdc)) using density functional theory (DFT) calculations. Previous studies have suggested that CO₂ can be captured via both outer- and inner-amine binding sites. Our findings reveal that CO₂ adsorption at the outer amine site is kinetically more favorable compared to the inner amine site, with a lower energy barrier of 1.34 eV for CO₂ physisorption to chemisorption compared to the inner amine, which has an activation barrier of 1.60 eV. Furthermore, we find that CO₂ adsorption is significantly enhanced in an alkaline environment, as deprotonation of the diamine molecule reduces the energy barrier to 0.24 eV. This theoretical study provides detailed insights into CO₂ adsorption in diamine-appended e-2-Mg₂(dobpdc) MOF, offering a deeper understanding of CO₂ capture mechanisms and valuable information for the advancement of effective CO₂ sequestration technologies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DFT" title="DFT">DFT</a>, <a
