The main result of this paper establishes that, under certain hypotheses for the dynamics f(.) and g(.), practical exponential stability in probability at the small neighborhood of the origin is equivalent to the existence of an appropriate Lyapunov function. Indeed, we establish exponential stability of stochastic differential equation when almost all the state trajectories are bounded and approach a sufficiently small neighborhood of the origin.

The combination of the linear quadratic estimation and the linear quadratic regulator allows the state estimation and the optimal control policy to be designed separately. This is known as the separation principle. In this paper, an efficient computational method is proposed to solve the linear quadratic Gaussian problem. In our approach, the Hamiltonian function is defined, and the necessary conditions are derived. In addition to this, the output error is defined and the least-square optimization problem is introduced. By determining the first-order necessary condition, the gradient of the sum squares of output error is established. On this point of view, the stochastic approximation approach is employed such that the optimal control policy is updated. Within a given tolerance, the iteration procedure would be stopped and the optimal solution of the linear-quadratic Gaussian problem is obtained. For illustration, an example of the linear-quadratic Gaussian problem is studied. The result shows the efficiency of the approach proposed. In conclusion, the applicability of the approach proposed for solving the linear quadratic Gaussian problem is highly demonstrated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=iteration%20procedure" title="iteration procedure">iteration procedure</a>, <a href="https://publications.waset.org/abstracts/search?q=least%20squares%20solution" title=" least squares solution"> least squares solution</a>, <a href="https://publications.waset.org/abstracts/search?q=linear%20quadratic%20Gaussian" title=" linear quadratic Gaussian"> linear quadratic Gaussian</a>, <a href="https://publications.waset.org/abstracts/search?q=output%20error" title=" output error"> output error</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20approximation" title=" stochastic approximation"> stochastic approximation</a> </p> <a href="https://publications.waset.org/abstracts/113018/least-squares-solution-for-linear-quadratic-gaussian-problem-with-stochastic-approximation-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113018.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">187</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">675</span> Pulse Generator with Constant Pulse Width</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rozita%20Borhan">Rozita Borhan</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanif%20Che%20Lah"> Hanif Che Lah</a>, <a href="https://publications.waset.org/abstracts/search?q=Wee%20Leong%20Son"> Wee Leong Son</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper is about method to produce a stable and accurate constant output pulse width regardless of the amplitude, period and pulse width variation of the input signal source.

It highlights the film’s reconstruction of the June 4th Incident as an intermediary device for the revival and haunting of the 1980s’ New Enlightenment Movement. The paper demonstrates how the June 4th Incident unfolds as historical trauma and collective experience of the Generation through Lou’s flickering narrative in both plot organization and visual representation, under an individualized and internal viewpoint. It further proposes that these revenants of the June 4th Incident translate into “realms of memory,” which lend themselves for biographical and historical reconstruction of the June 4th Incident based on a politics of embodiment. Through this, Lou and his contemporaries acquire agency to actively respond to the June 4th Incident as an “intimate revolt.” In this sense, the film revisits the New Enlightenment Movement in that they similarly construct rebellious connotations in a seemingly depoliticized manner. As the paper examines how an autobiographical film reconstructs, revisits, and responds to a historical event and its absence, it answers how individuals’ agency intertwines with and counteracts their historical living contexts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=new%20enlightenment%20movement" title="new enlightenment movement">new enlightenment movement</a>, <a href="https://publications.waset.org/abstracts/search?q=summer%20palace" title=" summer palace"> summer palace</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20June%204th%20incident" title=" the June 4th incident"> the June 4th incident</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20sixth%20generation%20of%20directors" title=" the sixth generation of directors"> the sixth generation of directors</a> </p> <a href="https://publications.waset.org/abstracts/148940/hauntology-of-history-intimate-revolt-in-lou-yes-summer-palace" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148940.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">126</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">672</span> Enhancement of Mechanical Properties and Thermal Conductivity of Oil Palm Shell Lightweight Concrete Reinforced with High Performance Polypropylene Fibres</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leong%20Tatt%20Loh">Leong Tatt Loh</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20Kun%20Yew"> Ming Kun Yew</a>, <a href="https://publications.waset.org/abstracts/search?q=Ming%20Chian%20Yew"> Ming Chian Yew</a>, <a href="https://publications.waset.org/abstracts/search?q=Lip%20Huat%20Saw"> Lip Huat Saw</a>, <a href="https://publications.waset.org/abstracts/search?q=Jing%20Han%20Beh"> Jing Han Beh</a>, <a href="https://publications.waset.org/abstracts/search?q=Siong%20Kang%20Lim"> Siong Kang Lim</a>, <a href="https://publications.waset.org/abstracts/search?q=Foo%20Wei%20Lee"> Foo Wei Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Oil palm shell (OPS) is the solid waste product from the palm oil sector of the agricultural industry and can be used as alternative coarse aggregates to substitute depleting conventional raw materials. This research aims to investigate the incorporation of various high-performance polypropylene (HPP) fibres with different geometry to enhance the mechanical properties and thermal conductivity of OPS lightweight concrete. The effect of different volume fractions (Vf) (0.05%, 0.10% and 0.15%) were studied for each fibre. The results reveal that the effectiveness of HPP fibres to increase the compressive strength at later ages was more pronounced than at early age. It is found that the use of HPP fibres reinforced OPS lightweight concrete (LWC) induced the advantageous of improving mechanical properties (compressive strength, flexural strength and splitting tensile strength) and thermal conductivity. Hence, this HPP fibres is a promising alternative solution to compensate lower mechanical properties as well as contribute to energy efficiency building material in the construction industry. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oil%20palm%20shell" title="oil palm shell">oil palm shell</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20performance%20polypropylene%20fibre" title=" high performance polypropylene fibre"> high performance polypropylene fibre</a>, <a href="https://publications.waset.org/abstracts/search?q=lightweight%20concrete" title=" lightweight concrete"> lightweight concrete</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20properties" title=" mechanical properties"> mechanical properties</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20conductivity" title=" thermal conductivity"> thermal conductivity</a> </p> <a href="https://publications.waset.org/abstracts/97550/enhancement-of-mechanical-properties-and-thermal-conductivity-of-oil-palm-shell-lightweight-concrete-reinforced-with-high-performance-polypropylene-fibres" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97550.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">207</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">671</span> Western and Eastern Ways of Special Warfare: The Strategic History of Special Operations from Western and Eastern Sources</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Kok%20Wey%20Leong">Adam Kok Wey Leong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Special operations were supposedly a new way of irregular warfare that was officially formed during World War 2. For example, the famous British Special Operations Executive (SOE) and the Americans’ Office for Strategic Services (OSS) – the forerunners of modern day CIA were born in World War 2. These special operations units were tasked with the conduct of sabotage and subversion activities behind enemy lines, placing great importance in forming Fifth Column activities and supporting resistance movements. This pointed to a paradoxical argument that modern day special operations is a product of Western modern military innovation but utilizing Eastern ways of ‘ungentlemanly’ warfare. This thesis is superfluous as special operations had been well practised by both ancient Western empires such as the Greeks and Romans, and around the same time in the East, such as in China, and Japan. This paper will describe the practice of special operations, first from the Western military history of the Greeks during the Peloponnesian war. It will then highlight the similar practice of special operations by the Near Eastern Assassins and Eastern militaries by using examples from the Chinese and the Japanese. This paper propounds that special operations, or ways of warfare as a whole, has no cultural and geographical divide, but rather very similarly practiced by men from all over the world. Ideas of fighting, killing and ultimately winning a war have similar undertones – attempts to find ways to win economically and at the least time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=special%20operations" title="special operations">special operations</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20culture" title=" strategic culture"> strategic culture</a>, <a href="https://publications.waset.org/abstracts/search?q=ways%20of%20warfare" title=" ways of warfare"> ways of warfare</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun%20Tzu" title=" Sun Tzu"> Sun Tzu</a>, <a href="https://publications.waset.org/abstracts/search?q=Frontinus" title=" Frontinus"> Frontinus</a> </p> <a href="https://publications.waset.org/abstracts/61434/western-and-eastern-ways-of-special-warfare-the-strategic-history-of-special-operations-from-western-and-eastern-sources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/61434.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">472</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">670</span> Comparing and Contrasting Western and Eastern Ways of War: Building a Universal Strategic Theory</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adam%20Kok%20Wey%20Leong">Adam Kok Wey Leong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The comparison between the Western ways of war and Eastern ways of war has raised contemporary debates on the validity of these arguments. The Western way of war is popularly propounded by Victor Davis Hanson as originating from the Greek hoplite tactics, direct military maneuvers, democratic principles and social freedom and cohesion that has continued to yield military success for the Western powers for centuries. On the other hand, the Eastern way of war has been deemed as relying on indirect tactics, deception, and ruses. This often accepted notion of the divide between Western and Eastern style does not sustain in view of the available classical strategic texts from both sides from the same period that has proposed similar principles of warfare. This paper analyses the similarities between classical strategic texts on war from the Eastern perspective namely Sun Tzu’s Art of War with a similar temporal strategic text from the West which is Sextus Iuluis Frontinus’s Stratagematon, and deduces answers to this core research question - Does the hypothesis of the existence of distinctive Western and Eastern ways of warfare stands? The main thesis advanced by this research is that ways of warfare share universal principles, and it transcends cultural and spatial boundaries. Warfare is a human endeavour, and the same moral actions guide humans from different geo-cultural spheres in warfare’s objectives, which are winning over an enemy in the most economical way and serve as a mean to an end. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ways%20of%20warfare" title="ways of warfare">ways of warfare</a>, <a href="https://publications.waset.org/abstracts/search?q=strategic%20culture" title=" strategic culture"> strategic culture</a>, <a href="https://publications.waset.org/abstracts/search?q=strategy" title=" strategy"> strategy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun%20Tzu" title=" Sun Tzu"> Sun Tzu</a>, <a href="https://publications.waset.org/abstracts/search?q=frontinus" title=" frontinus"> frontinus</a> </p> <a href="https://publications.waset.org/abstracts/72152/comparing-and-contrasting-western-and-eastern-ways-of-war-building-a-universal-strategic-theory" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72152.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">471</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">669</span> Extractive Bioconversion of Polyhydroxyalkanoates (PHAs) from Ralstonia Eutropha Via Aqueous Two-Phase System-An Integrated Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20K.%20Leong">Y.

PHAs are the biodegradable polymer produced by bacteria, which are in interest as a sustainable alternative to petrochemical-derived plastics; however, its commercial value has significantly limited by high production and recovery cost of PHA. Aqueous two-phase system (ATPS) offers different chemical and physical environments, which contains about 80-90% water delivers an excellent environment for partitioning of cells, cell organelles and biologically active substances. Extractive bioconversion via ATPS allows the integration of PHA upstream fermentation and downstream purification process, which reduces production steps and time, thus lead to cost reduction. The ability of Ralstonia eutropha to grow under different ATPS conditions was investigated for its potential to be used in a bioconversion system. Changes in tie-line length (TLL) and a volume ratio (Vr) were shown to have an effect on PHA partition coefficient. High PHA recovery yield of 65% with a relatively high purity of 73% was obtained in PEG 6000/Sodium sulphate system with 42.6 wt/wt % TLL and 1.25 Vr. Extractive bioconversion via ATPS is an attractive approach for the combination of PHA production and recovery process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aqueous%20two-phase%20system" title="aqueous two-phase system">aqueous two-phase system</a>, <a href="https://publications.waset.org/abstracts/search?q=extractive%20bioconversion" title=" extractive bioconversion"> extractive bioconversion</a>, <a href="https://publications.waset.org/abstracts/search?q=polyhydroxy%20alkanoates" title=" polyhydroxy alkanoates"> polyhydroxy alkanoates</a>, <a href="https://publications.waset.org/abstracts/search?q=purification" title=" purification "> purification </a> </p> <a href="https://publications.waset.org/abstracts/40313/extractive-bioconversion-of-polyhydroxyalkanoates-phas-from-ralstonia-eutropha-via-aqueous-two-phase-system-an-integrated-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40313.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">310</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">668</span> Nostalgic Tourism in Macau: The Bidirectional Causal Relationship between Destination Image and Experiential Value</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aliana%20Leong">Aliana Leong</a>, <a href="https://publications.waset.org/abstracts/search?q=T.%20C.%20Huan"> T.

This study intends to investigate the role of nostalgia in destination image, experiential value and their effect on subsequent behavioral intention. The survey used stratified sampling method to include respondents from all the nearby Asian regions. The sampling is based on the data of inbound tourists provided by the Statistics and Census Service (DSEC) of government of Macau. The questionnaire consisted of five sections of 5 point Likert scale questions: (1) nostalgia, (2) destination image both before and after experience, (3) expected value, (4) experiential value, and (5) future visit intention. Data was analysed with structural equation modelling. The result indicates that nostalgia plays an important part in forming destination image and experiential value before individual had a chance to experience the destination. The destination image and experiential value share a bidirectional causal relationship that eventually contributes to future visit intention. The study also discovered that while experiential value is more effective in generating destination image, the later contribute more to future visit intention. The research design measures destination image and experiential value before and after respondents had experience the destination. The distinction between destination image and expected/experiential value can be examined because the longitudinal design of research method. It also allows this study to observe how nostalgia translates to future visit intention. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nostalgia" title="nostalgia">nostalgia</a>, <a href="https://publications.waset.org/abstracts/search?q=destination%20image" title=" destination image"> destination image</a>, <a href="https://publications.waset.org/abstracts/search?q=experiential%20value" title=" experiential value"> experiential value</a>, <a href="https://publications.waset.org/abstracts/search?q=future%20visit%20intention" title=" future visit intention"> future visit intention</a> </p> <a href="https://publications.waset.org/abstracts/17798/nostalgic-tourism-in-macau-the-bidirectional-causal-relationship-between-destination-image-and-experiential-value" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17798.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">390</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">667</span> A Spatial Approach to Model Mortality Rates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yin-Yee%20Leong">Yin-Yee Leong</a>, <a href="https://publications.waset.org/abstracts/search?q=Jack%20C.%20Yue"> Jack C.

Among all mortality models, the Lee–Carter model is the most popular approach since it is fairly easy to use and has good accuracy in predicting mortality rates (e.g., for Japan and the USA). However, empirical studies from several countries have shown that the age parameters of the Lee–Carter model are not constant in time. Many modifications of the Lee–Carter model have been proposed to deal with this problem, including adding an extra cohort effect and adding another period effect. In this study, we propose a spatial modification and use clusters to explain why the age parameters of the Lee–Carter model are not constant. In spatial analysis, clusters are areas with unusually high or low mortality rates than their neighbors, where the “location” of mortality rates is measured by age and time, that is, a 2-dimensional coordinate. We use a popular cluster detection method—Spatial scan statistics, a local statistical test based on the likelihood ratio test to evaluate where there are locations with mortality rates that cannot be described well by the Lee–Carter model. We first use computer simulation to demonstrate that the cluster effect is a possible source causing the problem of the age parameters not being constant. Next, we show that adding the cluster effect can solve the non-constant problem. We also apply the proposed approach to mortality data from Japan, France, the USA, and Taiwan. The empirical results show that our approach has better-fitting results and smaller mean absolute percentage errors than the Lee–Carter model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mortality%20improvement" title="mortality improvement">mortality improvement</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%E2%80%93Carter%20model" title=" Lee–Carter model"> Lee–Carter model</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20statistics" title=" spatial statistics"> spatial statistics</a>, <a href="https://publications.waset.org/abstracts/search?q=cluster%20detection" title=" cluster detection"> cluster detection</a> </p> <a href="https://publications.waset.org/abstracts/93746/a-spatial-approach-to-model-mortality-rates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93746.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">171</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">666</span> Dietary Intake, Serum Vitamin D Status, and Sun Exposure of Malaysian Women of Different Ethnicity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Z.%20M.%20Chong">H.

Multiple factors for vitamin D insufficiency include poor intake of vitamin D rich food and inadequate sun exposure, especially among women working indoor with a sedentary lifestyle. Furthermore, Muslim women in Malaysia whose attire covers the entire body are likely to receive poor sun exposure. This research determined serum vitamin D status, vitamin D intake and sun exposure of women aged 20-45 years of different ethnicity in Kuala Lumpur, Malaysia. Blood samples were collected from 106 women for determination of serum 25(OH)D levels. Information about vitamin D intake and sun exposure were obtained by interviewing the subjects using pre-tested questionnaires. The overall mean serum 25(OH)D was found to be 29.9 ± 14 nmol/L. Vitamin D deficiency and insufficiency was prevalent and highest among the Malay women. Less than ten percent of the subjects in this study met the sufficient vitamin D level recommendation of ≥50 nmol/L. Intake of vitamin D rich food such as oily fishes was poor across the different ethnicity. Other dietary sources of vitamin D in the diet were fortified bread and skim milk. On the other hand, the median sunlight exposure of the subjects was 3.9 hours per week. The Malay women reported to have the highest duration being exposed to the sun. Nevertheless, due to cultural clothing practices, these women had the least body surface area exposed to sunlight, resulting in the lowest calculated sun index score compared to the Chinese and the Indians. Low intake of vitamin D rich foods and sun exposure were negatively correlated with serum 25(OH)D level. In conclusion, intake of food sources rich in vitamin D and adequate body surface area exposed to the sun are essential to ensure healthy vitamin D level. Supplementation of vitamin D may be recommended to women whom unable to meet these recommendations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=serum%2025-OH" title="serum 25-OH">serum 25-OH</a>, <a href="https://publications.waset.org/abstracts/search?q=sun%20exposure" title=" sun exposure"> sun exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20D%20food%20%20frequency" title=" vitamin D food frequency"> vitamin D food frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20D%20deficiency" title=" vitamin D deficiency"> vitamin D deficiency</a> </p> <a href="https://publications.waset.org/abstracts/91999/dietary-intake-serum-vitamin-d-status-and-sun-exposure-of-malaysian-women-of-different-ethnicity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91999.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 class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">665</span> Postharvest Studies Beyond Fresh Market Eating Quality: Phytochemical Changes in Peach Fruit During Ripening and Advanced Senescence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mukesh%20Singh%20Mer">Mukesh Singh Mer</a>, <a href="https://publications.waset.org/abstracts/search?q=Brij%20Lal%20Attri"> Brij Lal Attri</a>, <a href="https://publications.waset.org/abstracts/search?q=Raj%20Narayan"> Raj Narayan</a>, <a href="https://publications.waset.org/abstracts/search?q=Anil%20Kumar"> Anil Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Postharvest studies were conducted under the concept that fruit do not qualify for the fresh market may be used as a source of bioactive compounds. One peach (Prunus persica cvs Red June) were evaluated for their photochemical content and antioxidant capacity during the ripening and over ripening periods (advanced senescence) for 12 and 15 d, respectively. Firmness decreased rapidly during this period from an initial pre –ripe stage of 5.85 lb/in2 for peach until the fruit reached the fully ripe stage of lb/in2. In this study we evaluate the varietal performance in respect of the quality beyond fresh market eating and nutrition levels. The varieties are (T-1 F-16-23), (T-2 Florda king), (T-3 Nectarine), (T-4 Red June). The result pertaining are there the highest fruit length (68.50 mm), fruit breadth (71.38 mm), fruit weight (186.11 g) found in T4 Red June and fruit firmness (8.74 lb/in 2) found in T3-Nectarine. The acidity (1.66 %), ascorbic acid (440 mg/100 g), reducing sugar (19.77 %) and total sugar (51.73 %) found in T4- Red June, T-2 Florda King, T-3 Nectarine at harvesting time but decrease in fruit length ( 60.81 mm), fruit breadth (51.84 mm), fruit weight (143.03 g) found in T4 Red June and fruit firmness (6.29 lb/in 2) found in T3-Nectarine. The acidity (0.80 %), ascorbic acid (329.50 mg/100 g), reducing sugar (34.03 %) and total sugar (26.97 %) found in T1- F-16-23, T-2 Florda King, T-1 F-16-23 and T-3 Nectarine after 15 days in freeze conditions when will have been since reached beyond market. The study reveals that the size and yield good in Red June and the nutritional value higher in Florda King and Nectarine peach. Fruit firmness remained unchanged afterwards. In addition, total soluble solids in peach were basically similar during the ripening and over ripening periods. Further research on secondary metabolism regulation during ripening and advanced senescence is needed to obtain fruit as enriched dietary sources of bioactive compounds or for its use in alternative high value health markets including dietary supplements, functional foods cosmetics and pharmaceuticals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=metabolism" title="metabolism">metabolism</a>, <a href="https://publications.waset.org/abstracts/search?q=acidity" title=" acidity"> acidity</a>, <a href="https://publications.waset.org/abstracts/search?q=ascorbic%20acid" title=" ascorbic acid"> ascorbic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=pharmaceuticals" title=" pharmaceuticals"> pharmaceuticals</a> </p> <a href="https://publications.waset.org/abstracts/23442/postharvest-studies-beyond-fresh-market-eating-quality-phytochemical-changes-in-peach-fruit-during-ripening-and-advanced-senescence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23442.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">561</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">664</span> Presence of Nesting Parrot (Psittacula krameri borealis) Order Psitaciforme, Family Psittacidea in District Mirpurkhas Sindh Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aisha%20Liaquat%20Ali">Aisha Liaquat Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghulam%20Sarwar%20Gachal"> Ghulam Sarwar Gachal</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Yusuf%20Sheikh"> Muhammad Yusuf Sheikh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The parrot (Psittacula krameri borealis) commonly known as ‘Tota’ belongs to the order ‘Psittaciformes’ and family ‘Psittacidea’.

The communication theories employed to conduct this study was Agenda Setting Theory by McCombs and Shaw and the Framing theory by Goffman and Entman. The media’s coverage of National Disasters are of much concern to the general public. This research seeks to know how the Daily Graphic framed National Disasters that occurred in January 2015 and June 2015 respectively. The January 2015 National Disasters was termed as Fire Outbreaks while the June 2015 National Disasters was Twin Disasters. A total of 43 disaster news stories were analysed for this study. Out of the total number, 9 headline stories were analysed in the month of January 2015 and 34 headline stories were looked at in the month of June 2015. The study came up with five (5) themes. Through Content Analysis, the study also revealed that the theme of Action featured more than the other themes which are Fear, Violence, Sympathy and Confusion. Finally, the study showed the number of days disaster news headlines lasted in the Daily Graphic during the period stated above. It was revealed that the Fire Outbreaks in January 2015 appeared in the Daily Graphic for 8 days while the Twin Disasters appeared in 16 days in June 2015. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=national%20disaster%20framing" title="national disaster framing">national disaster framing</a>, <a href="https://publications.waset.org/abstracts/search?q=ghana" title=" ghana"> ghana</a>, <a href="https://publications.waset.org/abstracts/search?q=daily%20graphic" title=" daily graphic"> daily graphic</a>, <a href="https://publications.waset.org/abstracts/search?q=daily%20guide" title=" daily guide"> daily guide</a> </p> <a href="https://publications.waset.org/abstracts/73823/print-media-framing-of-national-disasters-a-content-analysis-of-the-daily-graphic-and-daily-guide" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73823.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">428</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">662</span> Effectiveness of Project Grit in Building Resilience among At-Risk Adolescents: A Case Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narash%20Narasimman">Narash Narasimman</a>, <a href="https://publications.waset.org/abstracts/search?q=Calvin%20Leong%20Jia%20Jun"> Calvin Leong Jia Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Raksha%20Karthik"> Raksha Karthik</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Englert"> Paul Englert</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Project Grit, a 12-week youth resilience program implemented by Impart and Spartans Boxing Club, aimed to help at-risk adolescents develop resilience through psychoeducation and mental health techniques for dealing with everyday stressors and adversity. The programme consists of two parts-1.5 hours of group therapy followed by 1 hour of boxing. Due to the novelty of the study, 6 male participants, aged 13 to 18, were recruited to participate in the study. Aim: This case study aims to examine the effectiveness of Project Grit in building resilience among at-risk adolescents. Methods: A case study design was employed to capture the complexity and uniqueness of the intervention, without oversimplifying or generalizing it. A 15-year-old male participant with a history of behavioural challenges, delinquency and gang involvement was selected for the study. Teacher, parent and child versions of the Strengths and Difficulties Questionnaire (SDQ) were administered to the facilitators, parents and participants respectively before and after the programme. Relevant themes from the qualitative interviews will be discussed. Results: Scores from all raters revealed improvements in most domains of the SDQ. Total difficulties scores across all raters improved from “very high” to “close to average”. High interrater reliability was observed (κ= .81). The participant reported learning methods to effectively deal with his everyday concerns using healthy coping strategies, developing a supportive social network, and building on his self efficacy. Themes from the subject’s report concurred with the improvement in SDQ scores. Conclusions: The findings suggest that Project Grit is a promising intervention for promoting resilience among at-risk adolescents. The teleological behaviourism framework and the combination of sports engagement and future orientation may be particularly effective in fostering resilience among this population. Further studies need to be conducted with a larger sample size to further validate the effectiveness of Project Grit. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=resilience" title="resilience">resilience</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20grit" title=" project grit"> project grit</a>, <a href="https://publications.waset.org/abstracts/search?q=adolescents" title=" adolescents"> adolescents</a>, <a href="https://publications.waset.org/abstracts/search?q=at-risk" title=" at-risk"> at-risk</a>, <a href="https://publications.waset.org/abstracts/search?q=boxing" title=" boxing"> boxing</a>, <a href="https://publications.waset.org/abstracts/search?q=future%20orientation" title=" future orientation"> future orientation</a> </p> <a href="https://publications.waset.org/abstracts/175111/effectiveness-of-project-grit-in-building-resilience-among-at-risk-adolescents-a-case-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175111.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">63</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">661</span> The Effects of Physiological Stress on Global and Regional Repolarisation in the Human Heart in Vivo </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=May%20Khei%20Hu">May Khei Hu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Leong"> Kevin Leong</a>, <a href="https://publications.waset.org/abstracts/search?q=Fu%20Siong%20Ng"> Fu Siong Ng</a>, <a href="https://publications.waset.org/abstracts/search?q=Nicholas%20Peter"> Nicholas Peter</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Sympathetic stimulation has been recognised as a potent stimulus of arrhythmogenesis in various cardiac pathologies, possibly by augmenting dispersion of repolarisation. The effects of sympathetic stimulation in healthy subjects however remain unclear. It is, therefore, crucial to first establish the effects of physiological stress on dispersion of repolarisation in healthy subjects before understanding these effects in pathological cardiac conditions. We hypothesised that activation-recovery interval (ARI; which is a surrogate of action potential duration) and dispersion of repolarisation decrease on sympathetic stimulation. Methods: Eight patients aged 18-55 years with structurally normal hearts underwent head-up tilt test (HUTT) and exercise tolerance test (ETT) while wearing the electrocardiographic imaging (ECGi) vest. Patients later underwent CT scan and the epicardial potentials are reconstructed using the ECGi software. Activation and recovery times were determined from the acquired electrograms. ARI was calculated and later corrected using Bazett’s formula. Global and regional dispersion of repolarisation were determined from standard deviation of the corrected ARI (ARIc). One-way analysis of variance (ANOVA) and Wilcoxon test were used to evaluate statistical significance. Results: Global ARIc increased significantly [p<0.01] when patients were tilted upwards but decreased significantly after five minutes [p<0.01]. A subsequent post- hoc analysis revealed that the decrease in R-R was more substantial compared to the change in ARI, resulting in the observed increase in ARIc. Global ARIc decreased on peak exercise [p<0.01] but increased on recovery [p<0.01]. Global dispersion increased significantly on peak exercise [p<0.05] although there were no significant changes in regional dispersion. There were no significant changes in both global and regional dispersion during tilt. Conclusion: ARIc decreases upon sympathetic stimulation in healthy subjects. Global dispersion of repolarisation increases upon exercise although there were no changes in global or regional dispersion during orthostatic stress. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dispersion%20of%20repolarisation" title="dispersion of repolarisation">dispersion of repolarisation</a>, <a href="https://publications.waset.org/abstracts/search?q=sympathetic%20stimulation" title=" sympathetic stimulation"> sympathetic stimulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Head-up%20tilt%20test%20%28HUTT%29" title=" Head-up tilt test (HUTT)"> Head-up tilt test (HUTT)</a>, <a href="https://publications.waset.org/abstracts/search?q=Exercise%20tolerance%20test%20%28ETT%29" title=" Exercise tolerance test (ETT)"> Exercise tolerance test (ETT)</a>, <a href="https://publications.waset.org/abstracts/search?q=Electrocardiographic%20imaging%20%28ECGi%29" title=" Electrocardiographic imaging (ECGi)"> Electrocardiographic imaging (ECGi)</a> </p> <a href="https://publications.waset.org/abstracts/137764/the-effects-of-physiological-stress-on-global-and-regional-repolarisation-in-the-human-heart-in-vivo" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137764.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">197</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">660</span> The Use of Facebook as a Social Media by Political Parties in the June 7 Election in Konya </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yasemin%20G%C3%BCl%C5%9Fen%20Y%C4%B1lmaz">Yasemin Gülşen Yılmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=S%C3%BCleyman%20Hakan%20Y%C4%B1lmaz"> Süleyman Hakan Yılmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammet%20Erbay"> Muhammet Erbay</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Social media is among the most important means of communication. Social media offers individuals and groups with an opportunity for participatory socialization over the internet, which is free of any time and place restrictions. Social media is a kind of interactive communication and bilateral social network. Various communication contents can be shared and put into mass circulation easily and quickly through social media. These sharings are not only limited to individuals but also happen to groups, institutions, and different constitutions. Their contents consist of any type of written message, audio and video files. We are living in the social media era now. It is not surprising that social media which has extensive communication facilities and massive prevalence is used in politics. Therefore, the use of social media (Facebook) by political parties during the Turkish general elections held on June 7, 2015, has been chosen as our research subject. Four parties namely, AKP, CHP, MHP and HDP who have the majority of votes in Turkey and participate in elections in Konya have been selected for our study. Their provincial centers’ and parliamentary candidates` use of social media (Facebook) on the last three days prior to the election have been examined and subjected to a qualitative analysis by means of content analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=social%20media" title="social media">social media</a>, <a href="https://publications.waset.org/abstracts/search?q=June%207%20general%20elections" title=" June 7 general elections"> June 7 general elections</a>, <a href="https://publications.waset.org/abstracts/search?q=politics" title=" politics"> politics</a>, <a href="https://publications.waset.org/abstracts/search?q=Facebook" title=" Facebook"> Facebook</a> </p> <a href="https://publications.waset.org/abstracts/36168/the-use-of-facebook-as-a-social-media-by-political-parties-in-the-june-7-election-in-konya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36168.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">404</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">659</span> Effects of Different Sowing Dates on Oil Yield of Castor (Ricinus communis L.)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C3%96zden%20%C3%96zt%C3%BCrk">Özden Öztürk</a>, <a href="https://publications.waset.org/abstracts/search?q=G%C3%B6zde%20P%C4%B1nar%20Gerem"> Gözde Pınar Gerem</a>, <a href="https://publications.waset.org/abstracts/search?q=Ay%C3%A7a%20Yenici"> Ayça Yenici</a>, <a href="https://publications.waset.org/abstracts/search?q=Burcu%20Haspolat"> Burcu Haspolat</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Castor (Ricinus communis L.) is one of the important non-edible oilseed crops having immense industrial and medicinal value. Oil yield per unit area is the ultimate target in growing oilseed plants and sowing date is one of the important factors which have a clear role in the production of active substances particularly in oilseeds. This study was conducted to evaluate the effect of sowing date on the seed and oil yield of castor in Central Anatolia in Turkey in 2011. The field experiment was set up in a completely randomized block design with three replication. Black Diamond-2 castor cultivar was used as plant material. The treatment was four sowing dates of May 10, May 25, June 10, June 25. In this research; seed yield, oil content and oil yield were investigated. Results showed that the effect of different sowing dates was significant on all of the characteristics. In general; delayed sowing dates, resulted in decreased seed yield, oil content and oil yield. The highest value of seed yield, oil content and oil yield (respectively, 2523.7 kg ha-1, 51.18% and 1292.2 kg ha-1) were obtained from the first sowing date (May 10) while the lowest seed yield, oil content and oil yield (respectively, 1550 kg ha-1, 43.67%, 677.3 kg ha-1) were recorded from the latest sowing date (June 25). Therefore, it can be concluded that early May could be recommended as an appropriate sowing date in the studied location and similar climates for achieved high oil yield of castor. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=castor%20bean" title="castor bean">castor bean</a>, <a href="https://publications.waset.org/abstracts/search?q=Ricinus%20communis%20L." title=" Ricinus communis L."> Ricinus communis L.</a>, <a href="https://publications.waset.org/abstracts/search?q=sowing%20date" title=" sowing date"> sowing date</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20yield" title=" seed yield"> seed yield</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20content" title=" oil content"> oil content</a> </p> <a href="https://publications.waset.org/abstracts/2642/effects-of-different-sowing-dates-on-oil-yield-of-castor-ricinus-communis-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2642.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">384</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">658</span> A Vaccination Program to Control an Outbreak of Acute Hepatitis A among MSM in Taiwan, 2016</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ying-Jung%20Hsieh">Ying-Jung Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=Angela%20S.%20Huang"> Angela S.

During 2010 to 2014, an average of 83 cases of locally-acquired disease was reported to Taiwan’s notifiable disease system. Taiwan Centers for Disease Control (TCDC) identified an outbreak of acute hepatitis A which began in June 2015. Of the 126 cases reported in 2015, 103 (82%) cases were reported during June–December and 95 cases (92%) of them were male. The average age of all male cases was 31 years (median, 29 years; range, 15–76 years). Among the 95 male cases, 49 (52%) were also infected with HIV, and all reported to have had sex with other men. To control this outbreak, TCDC launched a free hepatitis A vaccination program in January 2016 for close contacts of confirmed hepatitis A cases, including family members, sexual partners, and household contacts. Effect of the vaccination program was evaluated. Methods: All cases of hepatitis A reported to the National Notifiable Disease Surveillance System were included. A case of hepatitis A was defined as a locally-acquired disease in a person who had acute clinical symptoms include fever, malaise, loss of appetite, nausea or abdominal discomfort compatible with hepatitis, and tested positive for anti-HAV IgM during June 2015 to June 2016 in Taiwan. The rate of case accumulation was calculated using a simple regression model. Results: During January–June 2016, there were 466 cases of hepatitis A reported; of the 243 (52%) who were also infected with HIV, 232 (95%) had a history of having sex with men. Of the 346 cases that were followed up, 259 (75%) provided information on contacts but only 14 (5%) of them provided the name of their sexual partners. Among the 602 contacts reported, 349 (58%) were family members, 14 (2%) were sexual partners, and 239 (40%) were other household contacts. Among the 602 contacts eligible for free hepatitis A vaccination, 440 (73%) received the vaccine. There were 87 (25%) cases that refused to disclose their close contacts. The average case accumulation rate during January–June 2016 was 21.7 cases per month, which was 6.8 times compared to the average case accumulation rate during June–December 2015 of 3.2 cases per month. Conclusions: Despite vaccination program aimed to provide free hepatitis A vaccine to close contacts of hepatitis A patients, the outbreak continued and even gained momentum in transmission. Refusal by hepatitis A patients to provide names of their close contacts and rejection of contacts to take the hepatitis A vaccine may have contributed to the poor effect of the program. Targeted vaccination efforts of all MSM may be needed to control the outbreak among this population in the short term. In the long term, universal vaccination program is needed to prevent the infection of hepatitis A. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hepatitis%20A" title="hepatitis A">hepatitis A</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV" title=" HIV"> HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=men%20who%20have%20sex%20with%20men" title=" men who have sex with men"> men who have sex with men</a>, <a href="https://publications.waset.org/abstracts/search?q=vaccination" title=" vaccination"> vaccination</a> </p> <a href="https://publications.waset.org/abstracts/56588/a-vaccination-program-to-control-an-outbreak-of-acute-hepatitis-a-among-msm-in-taiwan-2016" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56588.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">256</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">657</span> Community Involvement in Reducing Maternal and Perinatal Mortality in Cross River State, Nigeria: 'The Saving Mother Giving Life' Strategic Approach in Cross River State</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oluwayemisi%20Femi-Pius">Oluwayemisi Femi-Pius</a>, <a href="https://publications.waset.org/abstracts/search?q=Kazeem%20Arogundade"> Kazeem Arogundade</a>, <a href="https://publications.waset.org/abstracts/search?q=Eberechukwu%20Eke"> Eberechukwu Eke</a>, <a href="https://publications.waset.org/abstracts/search?q=Jimmy%20Eko"> Jimmy Eko</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Globally, community involvement in improving their own health has been widely adopted as a strategy in Sub-Saharan Africa principally to ensure equitable access to essential health care as well as improve the uptake of maternal and newborn health services especially in poor-resource settings. Method: The Saving Mother Giving Life (SMGL) Initiative implemented by Pathfinder International with funding support from USAID conducted a Health Facility Assessment (HFA) and found out that maternal mortality ratio in Cross River State was 812 per 100,000 live birth and perinatal mortality was 160 per 1000 live birth. To reduce maternal and perinatal mortality, Pathfinder International mobilized, selected and trained community members as community volunteers, traditional birth attendants, and emergency transport service volunteer drivers mainly to address the delay in decision making and reaching the health facility among pregnant women. Results: The results showed that maternal mortality ratio in Cross River State decrease by 25% from 812 per 100,000 live birth at baseline to 206 per 100,000 live birth at June 2018 and perinatal mortality reduced by 35% from 160 per 100,000 at baseline to 58 per 1000 live birth at June 2018. Data also show that ANC visit increased from 7,451 to 11,344; institutional delivery increased from 8,931 at baseline to 10,784 in June 2018. There was also a remarkable uptake of post-partum family planning from 0 at baseline to 233 in June 2018. Conclusion: There is clear evidence that community involvement yields positive maternal outcomes and is pivotal for sustaining most health interventions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maternal%20mortality" title="maternal mortality">maternal mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=pathfinder%20international" title=" pathfinder international"> pathfinder international</a>, <a href="https://publications.waset.org/abstracts/search?q=perinatal%20mortality" title=" perinatal mortality"> perinatal mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=saving%20mother%20giving%20life" title=" saving mother giving life"> saving mother giving life</a> </p> <a href="https://publications.waset.org/abstracts/103551/community-involvement-in-reducing-maternal-and-perinatal-mortality-in-cross-river-state-nigeria-the-saving-mother-giving-life-strategic-approach-in-cross-river-state" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103551.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">192</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">656</span> Rapid Soil Classification Using Computer Vision, Electrical Resistivity and Soil Strength</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eugene%20Y.%20J.%20Aw">Eugene Y.

In Singapore, excavated soils from local construction projects are transported to Staging Grounds (SGs) to be reused as fill material for land reclamation. Excavated soils are mainly categorized into two groups (“Good Earth” and “Soft Clay”) based on particle size distribution (PSD) and water content (w) from soil investigation reports and on-site visual survey, such that proper treatment and usage can be exercised. However, this process is time-consuming and labour-intensive. Thus, a rapid classification method is needed at the SGs. Computer vision, four-probe soil electrical resistivity and CPT were combined into an innovative non-destructive and instantaneous classification method for this purpose. The computer vision technique comprises soil image acquisition using industrial grade camera; image processing and analysis via calculation of Grey Level Co-occurrence Matrix (GLCM) textural parameters; and decision-making using an Artificial Neural Network (ANN). Complementing the computer vision technique, the apparent electrical resistivity of soil (ρ) is measured using a set of four probes arranged in Wenner’s array. It was found from the previous study that the ANN model coupled with ρ can classify soils into “Good Earth” and “Soft Clay” in less than a minute, with an accuracy of 85% based on selected representative soil images. To further improve the technique, the soil strength is measured using a modified mini cone penetrometer, and w is measured using a set of time-domain reflectometry (TDR) probes. Laboratory proof-of-concept was conducted through a series of seven tests with three types of soils – “Good Earth”, “Soft Clay” and an even mix of the two. Validation was performed against the PSD and w of each soil type obtained from conventional laboratory tests. The results show that ρ, w and CPT measurements can be collectively analyzed to classify soils into “Good Earth” or “Soft Clay”. It is also found that these parameters can be integrated with the computer vision technique on-site to complete the rapid soil classification in less than three minutes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Computer%20vision%20technique" title="Computer vision technique">Computer vision technique</a>, <a href="https://publications.waset.org/abstracts/search?q=cone%20penetration%20test" title=" cone penetration test"> cone penetration test</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20resistivity" title=" electrical resistivity"> electrical resistivity</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20and%20non-destructive" title=" rapid and non-destructive"> rapid and non-destructive</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20classification" title=" soil classification"> soil classification</a> </p> <a href="https://publications.waset.org/abstracts/132538/rapid-soil-classification-using-computer-vision-electrical-resistivity-and-soil-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132538.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">218</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">655</span> Meiobenthic Diversity off Pudimadaka, Bay of Bengal, East Coast of India with Special Reference to Free-Living Marine Nematodes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20Annapurna">C.

Ten stations at depth between 10 and 40 m off Pudimadaka in Visakhapatnam (Lat.17º29′12″N and Long. 83º00′09″), East coast of India were investigated. Ninety species representing 3 major (meiofaunal) taxa namely foraminifera (2), copepoda (9), nematoda (58) and polychaeta (21) were encountered. Overall, meiofaunal (mean) abundance ranged from 2 individuals to 63 ind. 10cm-² with an average of 24.3 ind.10cm-2. The meiobenthic biomass varied between 0.135 to 0.48 mg.10cm-2 with an average 0.27 ± 0.12. On the whole, nematodes constituted 73.62% of the meiofauna in terms of numerical abundance. Shannon –Wiener index values were 2.053 ± 0.64 (June, 2008), 2.477 ± 0.177 (October 2008) and 2.2815±0.24 (March 2009). Multivariate analyses were used to define the most important taxon in nematode assemblages. Three nematode associations could be recognized off Pudimadaka coast, namely Laimella longicaudata, Euchromodora vulgaris and Sabatieria elongata assemblage (June, 2008); Catanema sp. and Leptosomatum sp. assemblage (October 2008) assemblage; Sabatieria sp. and Setosabatieria sp. assemblage (March 2009). Canonical correspondence analysis showed that temperature, organic matter, silt and mean particle diameter were important in controlling nematode community structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=meiofauna" title="meiofauna">meiofauna</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20nematode" title=" marine nematode"> marine nematode</a>, <a href="https://publications.waset.org/abstracts/search?q=biodiversity" title=" biodiversity"> biodiversity</a>, <a href="https://publications.waset.org/abstracts/search?q=community%20structure" title=" community structure"> community structure</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a> </p> <a href="https://publications.waset.org/abstracts/36370/meiobenthic-diversity-off-pudimadaka-bay-of-bengal-east-coast-of-india-with-special-reference-to-free-living-marine-nematodes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36370.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">304</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">654</span> Rapid Soil Classification Using Computer Vision with Electrical Resistivity and Soil Strength</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eugene%20Y.%20J.%20Aw">Eugene Y.

The results show that ρ, w and CPT measurements can be collectively analyzed to classify soils into “Good Earth” or “Soft Clay” and are feasible as complementing methods to the computer vision system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computer%20vision%20technique" title="computer vision technique">computer vision technique</a>, <a href="https://publications.waset.org/abstracts/search?q=cone%20penetration%20test" title=" cone penetration test"> cone penetration test</a>, <a href="https://publications.waset.org/abstracts/search?q=electrical%20resistivity" title=" electrical resistivity"> electrical resistivity</a>, <a href="https://publications.waset.org/abstracts/search?q=rapid%20and%20non-destructive" title=" rapid and non-destructive"> rapid and non-destructive</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20classification" title=" soil classification"> soil classification</a> </p> <a href="https://publications.waset.org/abstracts/144895/rapid-soil-classification-using-computer-vision-with-electrical-resistivity-and-soil-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144895.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">239</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">653</span> Metaphors in Egyptian News Headlines in Relation to the Egyptian Political Situation 2012-2013</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wesam%20Mohamed%20Abdel%20Khalek%20Ibrahim">Wesam Mohamed Abdel Khalek Ibrahim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the use of metaphors in Arabic political news discourse, focusing particularly on the headlines of the news articles relating to the Egyptian political situation in the period from June 2012 to October 2013. Metaphors are skilfully manipulated in the headlines to influence the public stance towards several events and entities including Egypt, Muslim Brotherhood (MB), Morsi, the June 30th uprising, Al-Sisi and the Armed Forces. The findings reveal that Arabic political news discourse shares basic features with its English counterpart, namely the use of metaphors as persuasive strategies and the presence of certain target domains. Insights gained from this study feed back into the conceptual metaphor theory by providing further evidence to the universality of metaphors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=conceptual%20metaphor%20theory" title="conceptual metaphor theory">conceptual metaphor theory</a>, <a href="https://publications.waset.org/abstracts/search?q=political%20discourse" title=" political discourse"> political discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=news%20discourse" title=" news discourse"> news discourse</a>, <a href="https://publications.waset.org/abstracts/search?q=Egyptian%20political%20situation" title=" Egyptian political situation"> Egyptian political situation</a> </p> <a href="https://publications.waset.org/abstracts/66807/metaphors-in-egyptian-news-headlines-in-relation-to-the-egyptian-political-situation-2012-2013" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66807.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">504</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">652</span> Analysis of Technical Efficiency and Its Determinants among Cattle Fattening Enterprises in Kebbi State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gona%20Ayuba">Gona Ayuba</a>, <a href="https://publications.waset.org/abstracts/search?q=Isiaka%20Mohammed"> Isiaka Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Kotom%20Mohammed%20Baba"> Kotom Mohammed Baba</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Aabubakar%20Maikasuwa"> Mohammed Aabubakar Maikasuwa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study examined the technical efficiency and its determinants of cattle fattening enterprises in Kebbi state, Nigeria.

The optimum angle for tilted surfaces varying from 0<sup>◦</sup> to 90<sup>◦</sup> in steps of 1<sup>◦ </sup>was computed. In present study, a theoretical model is used to predict the global solar radiation on a tilted surface and to obtain the optimum tilt angle for a solar collector in Bursa, Turkey. Global solar energy radiation on the solar collector surface with an optimum tilt angle is calculated for specific periods. It is determined that the optimum slope angle varies between 0<sup>◦</sup> (June) and 59<sup>◦</sup> (December) throughout the year. In winter (December, January, and February) the tilt should be 55<sup>◦</sup>, in spring (March, April, and May) 19.6<sup>◦</sup>, in summer (June, July, and August) 5.6<sup>◦</sup>, and in autumn (September, October, and November) 44.3<sup>◦</sup>. The yearly average of this value was obtained to be 31.1<sup>◦</sup> and this would be the optimum fixed slope throughout the year. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bursa" title="Bursa">Bursa</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20solar%20radiation" title=" global solar radiation"> global solar radiation</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20tilt%20angle" title=" optimum tilt angle"> optimum tilt angle</a>, <a href="https://publications.waset.org/abstracts/search?q=tilted%20surface" title=" tilted surface"> tilted surface</a> </p> <a href="https://publications.waset.org/abstracts/49458/optimization-of-tilt-angle-for-solar-collectors-a-case-study-for-bursa-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49458.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">260</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">650</span> Spatial Distribution and Time Series Analysis of COVID-19 Pandemic in Italy: A Geospatial Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Farhan%20Ul%20Moazzam">Muhammad Farhan Ul Moazzam</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamkeen%20Urooj%20Paracha"> Tamkeen Urooj Paracha</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghani%20Rahman"> Ghani Rahman</a>, <a href="https://publications.waset.org/abstracts/search?q=Byung%20Gul%20Lee"> Byung Gul Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasir%20Farid"> Nasir Farid</a>, <a href="https://publications.waset.org/abstracts/search?q=Adnan%20Arshad"> Adnan Arshad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The novel coronavirus pandemic disease (COVID-19) affected the whole globe, though there is a lack of clinical studies and its epidemiological features. But as per the observation, it has been seen that most of the COVID-19 infected patients show mild to moderate symptoms, and they get better without any medical assistance due to a better immune system to generate antibodies against the novel coronavirus. In this study, the active cases, serious cases, recovered cases, deaths and total confirmed cases had been analyzed using the geospatial inverse distance weightage technique (IDW) within the time span of 2nd March to 3rd June 2020. As of 3rd June, the total number of COVID-19 cases in Italy were 231,238, total deaths 33,310, serious cases 350, recovered cases 158,951, and active cases were 39,177, which has been reported by the Ministry of Health, Italy. March 2nd-June 3rd, 2020 a sum of 231,238 cases has been reported in Italy out of which 38.68% cases reported in the Lombardia region with a death rate of 18%, which is high from its national mortality rate followed by Emilia-Romagna (14.89% deaths), Piemonte (12.68% deaths), and Vento (10% deaths). As per the total cases in the region, the highest number of recoveries has been observed in Umbria (92.52%), followed by Basilicata (87%), Valle d'Aosta (86.85%), and Trento (84.54%). The COVID-19 evolution in Italy has been particularly found in the major urban area, i.e., Rome, Milan, Naples, Bologna, and Florence. Geospatial technology played a vital role in this pandemic by tracking infected patient, active cases, and recovered cases. Geospatial techniques are very important in terms of monitoring and planning to control the pandemic spread in the country. <p class="card-text"><strong>Keywords:</strong> <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=public%20health" title=" public health"> public health</a>, <a href="https://publications.waset.org/abstracts/search?q=geospatial%20analysis" title=" geospatial analysis"> geospatial analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=IDW" title=" IDW"> IDW</a>, <a href="https://publications.waset.org/abstracts/search?q=Italy" title=" Italy"> Italy</a> </p> <a href="https://publications.waset.org/abstracts/130341/spatial-distribution-and-time-series-analysis-of-covid-19-pandemic-in-italy-a-geospatial-perspective" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130341.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">154</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">649</span> Targeted Delivery of Docetaxel Drug Using Cetuximab Conjugated Vitamin E TPGS Micelles Increases the Anti-Tumor Efficacy and Inhibit Migration of MDA-MB-231 Triple Negative Breast Cancer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20K.%20Rajaletchumy">V.

Leong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Triple negative breast cancers (TNBC) can be classified as one of the most aggressive with a high rate of local recurrences and systematic metastases. TNBCs are insensitive to existing hormonal therapy or targeted therapies such as the use of monoclonal antibodies, due to the lack of oestrogen receptor (ER) and progesterone receptor (PR) and the absence of overexpression of human epidermal growth factor receptor 2 (HER2) compared with other types of breast cancers. The absence of targeted therapies for selective delivery of therapeutic agents into tumours, led to the search for druggable targets in TNBC. In this study, we developed a targeted micellar system of cetuximab-conjugated micelles of D-α-tocopheryl polyethylene glycol succinate (vitamin E TPGS) for targeted delivery of docetaxel as a model anticancer drug for the treatment of TNBCs. We examined the efficacy of our micellar system in xenograft models of triple negative breast cancers and explored the effect of the micelles on post-treatment tumours in order to elucidate the mechanism underlying the nanomedicine treatment in oncology. The targeting micelles were found preferentially accumulated in tumours immediately after the administration of the micelles compare to normal tissue. The fluorescence signal gradually increased up to 12 h at the tumour site and sustained for up to 24 h, reflecting the increases in targeted micelles (TPFC) micelles in MDA-MB-231/Luc cells. In comparison, for the non-targeting micelles (TPF), the fluorescence signal was evenly distributed all over the body of the mice. Only a slight increase in fluorescence at the chest area was observed after 24 h post-injection, reflecting the moderate uptake of micelles by the tumour. The successful delivery of docetaxel into tumour by the targeted micelles (TPDC) exhibited a greater degree of tumour growth inhibition than Taxotere® after 15 days of treatment. The ex vivo study has demonstrated that tumours treated with targeting micelles exhibit enhanced cell cycle arrest and attenuated proliferation compared with the control and with those treated non-targeting micelles. Furthermore, the ex vivo investigation revealed that both the targeting and non-targeting micellar formulations shows significant inhibition of cell migration with migration indices reduced by 0.098- and 0.28-fold, respectively, relative to the control. Overall, both the in vivo and ex vivo data increased the confidence that our micellar formulations effectively targeted and inhibited EGF-overexpressing MDA-MB-231 tumours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodegradable%20polymers" title="biodegradable polymers">biodegradable polymers</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20nanotechnology" title=" cancer nanotechnology"> cancer nanotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=drug%20targeting" title=" drug targeting"> drug targeting</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20biomaterials" title=" molecular biomaterials"> molecular biomaterials</a>, <a href="https://publications.waset.org/abstracts/search?q=nanomedicine" title=" nanomedicine"> nanomedicine</a> </p> <a href="https://publications.waset.org/abstracts/50350/targeted-delivery-of-docetaxel-drug-using-cetuximab-conjugated-vitamin-e-tpgs-micelles-increases-the-anti-tumor-efficacy-and-inhibit-migration-of-mda-mb-231-triple-negative-breast-cancer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50350.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">281</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">648</span> Building a Stochastic Simulation Model for Blue Crab Population Evolution in Antinioti Lagoon</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikolaos%20Simantiris">Nikolaos Simantiris</a>, <a href="https://publications.waset.org/abstracts/search?q=Markos%20Avlonitis"> Markos Avlonitis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work builds a simulation platform, modeling the spatial diffusion of the invasive species Callinectes sapidus (blue crab) as a random walk, incorporating also generation, fatality, and fishing rates modeling the time evolution of its population. Antinioti lagoon in West Greece was used as a testbed for applying the simulation model. Field measurements from June 2020 to June 2021 on the lagoon’s setting, bathymetry, and blue crab juveniles provided the initial population simulation of blue crabs, as well as biological parameters from the current literature were used to calibrate simulation parameters. The scope of this study is to render the authors able to predict the evolution of the blue crab population in confined environments of the Ionian Islands region in West Greece. The first result of the simulation experiments shows the possibility for a robust prediction for blue crab population evolution in the Antinioti lagoon. <p class="card-text"><strong>Keywords:</strong>
