These often result to low oil production and excessive water and/or gas production. Since over 50 years of oil production in the Niger delta, it is apparent that most of the oil fields in the region have reached their mature stages, thereby susceptible to coning tendencies. As a result of these, a good number of wells have been shut-in and abandoned, with significant amount of oil left unproduced. Analysis of the movement of fluid contacts in the reservoir is a significant aspect of reservoir studies and can assist in the management of coning tendencies and production performance of reservoirs in a mature field. This study, therefore, seeks to evaluate the occurrence of coning through the movement of fluid contacts (GOC and OWC) and determine the critical rate for controlling coning tendencies in mature oil field. This study applies the principle of Nodal analysis to calibrate the thin oil column of a reservoir of a mature field, and was graphically evaluated using the Joshi’s equation of critical rate for gas-oil system and oil-water system respectively. A representative Proxy equation was developed and sensitivity analysis carried out to determine the trend of critical rate as the oil column is been depleted. The result shows the trend in the movement of the GOC and OWC, and the critical rate, beyond which will result in excessive water and gas production, resulting to decreasing oil production from the reservoir. This result of this study can be used as a first pass assessment in the development of mature oil field reservoirs anticipated to experience water and/or gas coning during production. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coning" title="coning">coning</a>, <a href="https://publications.waset.org/abstracts/search?q=fluid%20contact%20movement" title=" fluid contact movement"> fluid contact movement</a>, <a href="https://publications.waset.org/abstracts/search?q=mature%20oil%20field" title=" mature oil field"> mature oil field</a>, <a href="https://publications.waset.org/abstracts/search?q=oil%20production" title=" oil production"> oil production</a> </p> <a href="https://publications.waset.org/abstracts/90505/evaluation-of-critical-rate-in-mature-oil-field-with-dynamic-oil-rim-fluid-contacts-in-the-niger-delta" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/90505.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">242</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">8584</span> Energy Efficiency Analysis of Electrical Submersible Pump on Mature Oil Field Offshore Java Sea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marda%20Vidrianto">Marda Vidrianto</a>, <a href="https://publications.waset.org/abstracts/search?q=Tania%20Surya%20Utami"> Tania Surya Utami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Electrical Submersible Pump (ESP) is an artificial lift of choice to produce oil on Offshore Java Sea. It is selected based on the production rate capacity and running life expectation. ESP performance in a mature field is highly affected by oil well conditions. The presence of sand, scale, gas, and low influx will create unstable ESP operation hence lowering the run life expectation and system efficiency. This paper reviews the current energy usage and efficiency on every part of the ESP system. The hydraulic and electrical losses, as well as system efficiency for each well, are calculated to identify energy losses and the possibility for improvement. It is shown that high back pressure on the system and low-efficiency pump are the major contributors to energy losses. It was found that optimized production rate and the use of advanced technology on pump and motor unit could improve energy efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=advance%20technology" title="advance technology">advance technology</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20efficiency" title=" energy efficiency"> energy efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=ESP" title=" ESP"> ESP</a>, <a href="https://publications.waset.org/abstracts/search?q=mature%20field" title=" mature field"> mature field</a>, <a href="https://publications.waset.org/abstracts/search?q=production%20rate" title=" production rate"> production rate</a> </p> <a href="https://publications.waset.org/abstracts/93119/energy-efficiency-analysis-of-electrical-submersible-pump-on-mature-oil-field-offshore-java-sea" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93119.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">342</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">8583</span> Efficient Callus Induction and Plant Regeneration from Mature Embryo Culture of Barley (Hordeum vulgare L.)

Immature embryos are the most widely used explant source for <em>in vitro</em> regeneration in barley (<em>Hordeum vulgare</em> L.). However, immature embryos require the continuous growth of donor plants and the suitable stage for their culture is also certainly limited. On the other hand, mature embryos can be procured and stored easily; they can be studied throughout the year. In this study, an effective callus induction and plant regeneration were aimed to develop from mature embryos of different barley genotypes. The effect of medium (MS<sub>1</sub> and MS<sub>2</sub>), auxin type (2,4-D, dicamba, picloram and 2,4,5-T) and concentrations (2, 4, 6 mg/l) on callus formation and effect of cytokinin type (TDZ, BAP) and concentrations (0.2, 0.5, 1.0 mg/l) on green plant regeneration were evaluated in mature embryo culture of barley. Callus and shoot formation was successful for all genotypes. By depending on genotype, MS<sub>1 </sub>is the best medium, 4 mg/l dicamba is the best growth regulator in the callus induction and MS<sub>1 </sub>is the best medium, 1 mg/l BAP is the best growth regulator in the shoot formation were determined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=barley" title="barley">barley</a>, <a href="https://publications.waset.org/abstracts/search?q=callus" title=" callus"> callus</a>, <a href="https://publications.waset.org/abstracts/search?q=embryo%20culture" title=" embryo culture"> embryo culture</a>, <a href="https://publications.waset.org/abstracts/search?q=mature%20embryo" title=" mature embryo"> mature embryo</a> </p> <a href="https://publications.waset.org/abstracts/49872/efficient-callus-induction-and-plant-regeneration-from-mature-embryo-culture-of-barley-hordeum-vulgare-l-genotypes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49872.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">326</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">8582</span> Using of Bimolecular Fluorescence Complementation (BiFC) Assays to Study Homo and/ or Heterodimerization of Laminin Receptor 37 LRP/ 67 LR with Galectin-3</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fulwah%20Alqahtani">Fulwah Alqahtani</a>, <a href="https://publications.waset.org/abstracts/search?q=Jafar%20Mahdavi"> Jafar Mahdavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Lee%20Weldon"> Lee Weldon</a>, <a href="https://publications.waset.org/abstracts/search?q=Nick%20Holliday"> Nick Holliday</a>, <a href="https://publications.waset.org/abstracts/search?q=Dlawer%20Ala%27Aldeen"> Dlawer Ala'Aldeen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There are two isoforms of laminin receptor; monomeric 37 kDa laminin receptor precursor (37 LRP) and mature 67 kDa laminin receptor (67 LR).

Gal-3 is the only member of the chimera-type group of galectins, and has one C-terminal carbohydrate recognition domain (CRD) that is responsible for binding the ß-galactoside moieties of mono- or oligosaccharides on several host and microbial molecules.

The breeders mate and produce offspring while the non-breeding helpers increase the chick production rate through help in mate-finding and allo-parenting. However, the chicks also cooperate to raise their younger siblings through warming, defending and food sharing. Although, the existing literatures describes the evolution of allo-parenting in birds but do not differentiate the significance of allo-parenting in sexually immature and mature helpers separately. This study addresses the significance of both immature and mature helpers’ contribution to the total sustainable bird population in a breeding site using Blue-tailed bee-eater as a test-bed species. To serve this purpose, a mathematical model has been built considering each social status and chicks as separate but interactive compartments. Also, to observe the dynamics of each social status with changing prey abundance, a prey population has been introduced as an additional compartment. The model was analyzed for stability condition and was validated using field-data. A simulation experiment was then performed to observe the change in equilibria with a varying helping rate from both the helpers. The result from the simulation experiment suggest that the cooperative breeding population changes its population sizes significantly with a change in helping rate from the sexually immature helpers. On the other hand, the mature helpers do not contribute to the stability of the population equilibrium as much as the immature helpers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blue-tailed%20bee%20eater" title="Blue-tailed bee eater">Blue-tailed bee eater</a>, <a href="https://publications.waset.org/abstracts/search?q=Altruism" title=" Altruism"> Altruism</a>, <a href="https://publications.waset.org/abstracts/search?q=Mathematical%20Ethology" title=" Mathematical Ethology"> Mathematical Ethology</a>, <a href="https://publications.waset.org/abstracts/search?q=Behavioural%20modelling" title=" Behavioural modelling"> Behavioural modelling</a> </p> <a href="https://publications.waset.org/abstracts/123120/estimating-interdependence-of-social-statuses-in-a-cooperative-breeding-birds-through-mathematical-modelling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123120.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">162</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">8580</span> Significance of Water Saving through Subsurface Drip Irrigation for Date Palm Trees</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20I.%20Al-Amoud">Ahmed I.

In the first laboratory study, eight subsurface drip irrigation lines available locally, were selected and a number of experiments were made to evaluate line hydraulic characteristics to insure it's suitability for drip irrigation design requirements and high performance to select the best for field experiments. The second study involves field trials on mature date palm trees to study the effect of subsurface drip irrigation system on the yield and water consumption of date palms, and to compare that with the traditional surface drip irrigation system. Experiments were conducted in Alwatania Agricultural Project, on 50 mature palm trees (17 years old) of Helwa type with 10 meters spacing between rows and between trees. A high efficiency subsurface line (Techline) was used based on the results of the first study. Irrigation scheduling was made through a soil moisture sensing device to ensure enough soil water levels in the soil. Experiment layouts were installed during 2001 season, measurements continued till end of 2008 season. Results have indicated that there is an increase in the yield and a considerable saving in water compared to the conventional drip irrigation method. In addition there were high increases in water use efficiency using the subsurface system. The subsurface system proves to be durable and highly efficient for irrigating date palm trees. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=drip%20irrigation" title="drip irrigation">drip irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=subsurface%20drip%20irrigation" title=" subsurface drip irrigation"> subsurface drip irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20trees" title=" date palm trees"> date palm trees</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20water%20use" title=" date palm water use"> date palm water use</a>, <a href="https://publications.waset.org/abstracts/search?q=date%20palm%20yield" title=" date palm yield"> date palm yield</a> </p> <a href="https://publications.waset.org/abstracts/1984/significance-of-water-saving-through-subsurface-drip-irrigation-for-date-palm-trees" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1984.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">8579</span> Mature Cystic Teratomas of Ovary: A Series of 19 Cases with Rare Malignant Transformation in Three</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Parveen%20Kundu">Parveen Kundu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nitika%20Chawla"> Nitika Chawla</a>, <a href="https://publications.waset.org/abstracts/search?q=Ruchi%20Agarwal"> Ruchi Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Swaran%20Kaur"> Swaran Kaur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Mature cystic teratoma is a benign, most common tumor of the ovary occurring mostly in young and middle-aged females. This study consists of 19 cases of mature cystic teratomas which were received in the Department Of Pathology over a period of two years. There were malignant transformations observed in three cases, which makes it very important for pathologists to thoroughly examine the entire specimen of mature cystic teratomas. Material and Methods: Nineteen reported cases of mature cystic teratomas were received in Deptt. Of Pathology, BPS GMC Khanpur Kalan, Sonepat, over a two-year period from November 2020 to October 2022 and reviewed retrospectively. Data regarding age, size, laterality, gross, morphological features, and surgery performed were retrieved from pathological archives. Results: In our study, the most common age of presentation was the 20-40 year age group. The most common presenting complaint was fullness in the abdomen or abdominal distension. Four out of 19 cases studied cases presented with bilateral ovarian cysts. Tumor size ranged from 6 to 20 cm in diameter. In seven cases, cysts were greater than or equal to 10 cm in diameter. Three cases showed malignant transformation. Conclusion: It is very important to thoroughly examine the contralateral ovary to rule out bilateral presentation. A furthermost thorough examination is advised in tumors of size >10 cm and in tumors with solid areas to rule out any malignant transformation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=teratoma" title="teratoma">teratoma</a>, <a href="https://publications.waset.org/abstracts/search?q=ovary" title=" ovary"> ovary</a>, <a href="https://publications.waset.org/abstracts/search?q=malignant" title=" malignant"> malignant</a>, <a href="https://publications.waset.org/abstracts/search?q=transformation" title=" transformation"> transformation</a> </p> <a href="https://publications.waset.org/abstracts/169478/mature-cystic-teratomas-of-ovary-a-series-of-19-cases-with-rare-malignant-transformation-in-three" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169478.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">87</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">8578</span> Targeting and Developing the Remaining Pay in an Ageing Field: The Ovhor Field Experience</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Christian%20Ihwiwhu">Christian Ihwiwhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Nnamdi%20Obioha"> Nnamdi Obioha</a>, <a href="https://publications.waset.org/abstracts/search?q=Udeme%20John"> Udeme John</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Bobade"> Edward Bobade</a>, <a href="https://publications.waset.org/abstracts/search?q=Oghenerunor%20Bekibele"> Oghenerunor Bekibele</a>, <a href="https://publications.waset.org/abstracts/search?q=Adedeji%20Awujoola"> Adedeji Awujoola</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibi-Ada%20Itotoi"> Ibi-Ada Itotoi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Understanding the complexity in the distribution of hydrocarbon in a simple structure with flow baffles and connectivity issues is critical in targeting and developing the remaining pay in a mature asset. Subtle facies changes (heterogeneity) can have a drastic impact on reservoir fluids movement, and this can be crucial to identifying sweet spots in mature fields. This study aims to evaluate selected reservoirs in Ovhor Field, Niger Delta, Nigeria, with the objective of optimising production from the field by targeting undeveloped oil reserves, bypassed pay, and gaining an improved understanding of the selected reservoirs to increase the company’s reservoir limits. The task at the Ovhor field is complicated by poor stratigraphic seismic resolution over the field. 3-D geological (sedimentology and stratigraphy) interpretation, use of results from quantitative interpretation, and proper understanding of production data have been used in recognizing flow baffles and undeveloped compartments in the field. The full field 3-D model has been constructed in such a way as to capture heterogeneities and the various compartments in the field to aid the proper simulation of fluid flow in the field for future production prediction, proper history matching and design of good trajectories to adequately target undeveloped oil in the field. Reservoir property models (porosity, permeability, and net-to-gross) have been constructed by biasing log interpreted properties to a defined environment of deposition model whose interpretation captures the heterogeneities expected in the studied reservoirs. At least, two scenarios have been modelled for most of the studied reservoirs to capture the range of uncertainties we are dealing with. The total original oil in-place volume for the four reservoirs studied is 157 MMstb. The cumulative oil and gas production from the selected reservoirs are 67.64 MMstb and 9.76 Bscf respectively, with current production rate of about 7035 bopd and 4.38 MMscf/d (as at 31/08/2019). Dynamic simulation and production forecast on the 4 reservoirs gave an undeveloped reserve of about 3.82 MMstb from two (2) identified oil restoration activities. These activities include side-tracking and re-perforation of existing wells. This integrated approach led to the identification of bypassed oil in some areas of the selected reservoirs and an improved understanding of the studied reservoirs. New wells have/are being drilled now to test the results of our studies, and the results are very confirmatory and satisfying. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=facies" title="facies">facies</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20baffle" title=" flow baffle"> flow baffle</a>, <a href="https://publications.waset.org/abstracts/search?q=bypassed%20pay" title=" bypassed pay"> bypassed pay</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneities" title=" heterogeneities"> heterogeneities</a>, <a href="https://publications.waset.org/abstracts/search?q=history%20matching" title=" history matching"> history matching</a>, <a href="https://publications.waset.org/abstracts/search?q=reservoir%20limit" title=" reservoir limit"> reservoir limit</a> </p> <a href="https://publications.waset.org/abstracts/119324/targeting-and-developing-the-remaining-pay-in-an-ageing-field-the-ovhor-field-experience" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/119324.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">129</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">8577</span> The Effects of Affective Dimension of Face on Facial Attractiveness</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyung-Ja%20Cho">Kyung-Ja Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Sun%20Jin%20Park"> Sun Jin Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study examined what effective dimension affects facial attractiveness. Two orthogonal dimensions, sharp-soft and babyish-mature, were used to rate the levels of facial attractiveness in 20’s women.

In the background of China's New Normal, numbers of mature industrial zones are stepping into a new stage of inventory development instead of increment development. The aim of this study is to discover new characteristics and problems and corresponding inventory planning guidance of mature industrial zones. A case of Yangzhou Hi-Tech Industrial Development Zone is reported in this study. Based on a historical analysis and data analysis of land-use, it is found that land-use of the zone is near saturation and signs of land updating have begun to appear. It is observed that the zone is facing problems including disorder of land development, low economic productivity and single function. Through the data of economic output, tax contribution, industrial category, industry life cycle and environmental influence, a comprehensive assessment based on two dimensions, economic benefits and industrial matchup, is made upon every parcel in the zone. According to the assessment, the zone is divided into spatial units of the update with specific planning guidance. It comes to a conclusion as four directions of inventory planning guidance in mature industrial zones: moving industries with poor economic benefit and negative environmental influence, adding urban function and new industrial function to the zone, optimizing the function of important space, and restricting the mass layout of the real estate industry to provide space for industrial upgrading. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=China%27s%20new%20normal" title="China's new normal">China's new normal</a>, <a href="https://publications.waset.org/abstracts/search?q=mature%20industrial%20zones" title=" mature industrial zones"> mature industrial zones</a>, <a href="https://publications.waset.org/abstracts/search?q=land-use" title=" land-use"> land-use</a>, <a href="https://publications.waset.org/abstracts/search?q=inventory%20planning" title=" inventory planning "> inventory planning </a> </p> <a href="https://publications.waset.org/abstracts/33123/research-on-characteristics-and-inventory-planning-counter-measure-of-mature-industrial-zones-in-the-background-of-chinas-new-normal" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33123.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">452</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">8575</span> Antioxidant Activity of Morinda citrifolia L.

This study investigated the phytophenolics content and antioxidant activity of green, mature green and ripe noni fruits. The vitamin C content ranged from 41.12 ± 0.083 to 143.63 ± 0.146 mg / 100 ml in fresh noni fruits. Ripe fruits contained the highest level of ascorbic acid followed by mature green and green fruits (p < 0.05). The total phenol content ranged from 0.909 (green) to 2.305 (ripe) mg / g of FW whilst the total flavonoid content ranged from 1.054 (green) to 2.116 (ripe) mg/g of FW. The in vitro antioxidant activity of the Morinda citrifolia L. extracts was also analysed using FRAP and TEAC assays. The reducing power of the fruit extracts as assessed by the FRAP assay decreased in the following order: ripe > mature green > green (p < 0.05). The TEAC values ranged from 0.2631 to 0.8921 µmol / g FW, with extracts of fruits at the mature green stage having highest values followed by fruits at the ripe and green stage respectively (p < 0.05). High correlation values were obtained between total phenolics, total flavonoids, ascorbic acid contents and the TEAC and FRAP assays (r > 0.8). Noni fruit extracts (0.2 and 0.4 % m / m) were compared with BHT (0.02 % m / m) on their ability to protect canola oil and mayonnaise, prepared with canola oil, against lipid oxidation during storage at 40°C. Mature green and ripe extracts, at both concentrations, were more effective than BHT in retarding oxidation in both food systems as evidenced by peroxide value and conjugated diene value determinations. Noni extracts were also very effective in inhibiting lipid peroxidation in tuna fish homogenates, assessed using TBARS assay. Noni fruits at the mature green and ripe stages represent a potential source of natural antioxidants for use a food additive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title="antioxidant">antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=canola%20oil" title=" canola oil"> canola oil</a>, <a href="https://publications.waset.org/abstracts/search?q=mayonnaise" title=" mayonnaise"> mayonnaise</a>, <a href="https://publications.waset.org/abstracts/search?q=Morinda%20citrifolia%20L.%20fruit%20extracts" title=" Morinda citrifolia L. fruit extracts"> Morinda citrifolia L. fruit extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20flavonoids" title=" total flavonoids"> total flavonoids</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20phenol" title=" total phenol"> total phenol</a> </p> <a href="https://publications.waset.org/abstracts/70961/antioxidant-activity-of-morinda-citrifolia-l-noni-fruits-at-three-different-stages-of-maturity-in-food-systems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70961.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">258</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">8574</span> Sustaining the Mitochondrial Transcription Factor A in Sperm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Betty%20Anson">Betty Anson</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Researchers have found that mature sperm cells are not only devoid of mature MTDNA (mitochondrial DNA) but also lack a particular protein essential for DNA maintenance, known as mitochondrial transcription factor A, or TFAM (transcription factor A mitochondria).

Research was conducted based on the case study of the City of Ivanic-Grad public buildings energy demand and Ivanic oil filed that is situated in the same area. Since the City of Ivanic is one of the few cities in the EU where hydrocarbon exploitation has been taking place for decades almost entirely in urban area, decommissioning of oil wells is inevitable; therefore, the research goal was to investigate how to extend the life-time of the reservoir by exploiting geothermal brine beneath the oil reservoir in an environmental friendly manner. This kind of a project is extremely complex in all segments, from documentation preparation, implementation of technological solutions, and providing ecological measures for environmentally acceptable geothermal energy production and utilization. New mining activities that will be needed for the development of geothermal project at the observed Hydrocarbon Exploitation Field Ivanic will be carried out in order to prepare wells for increasing geothermal brine production. These operations involve the conversion of existing wells (well completion for conversion of the observation wells to production ones) along with workover activities, installation of new heat exchangers, and pipelines. Since the wells are in the urban area of the City of Ivanic-Grad in high density populated area, the inhabitants will be exposed to the different environmental impacts during preparation phase of the project. For the purpose of performing workovers, it will be necessary to secure access to wellheads of existing wells. This paper gives guidelines for describing potential impacts on environment components that could occur during geothermal production preparation on existing mature oil filed, recommends possible protection measures to mitigate these impacts, and gives recommendations for environmental monitoring. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=geothermal%20energy%20production" title="geothermal energy production">geothermal energy production</a>, <a href="https://publications.waset.org/abstracts/search?q=mature%20oil%20filed" title=" mature oil filed"> mature oil filed</a>, <a href="https://publications.waset.org/abstracts/search?q=environmental%20impact%20assessment" title=" environmental impact assessment"> environmental impact assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=underlying%20aquifer%20thermal%20energy" title=" underlying aquifer thermal energy"> underlying aquifer thermal energy</a> </p> <a href="https://publications.waset.org/abstracts/122018/recommendations-for-environmental-impact-assessment-of-geothermal-projects-on-mature-oil-fields" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122018.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">149</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">8572</span> Effects of Gamma Radiation on Tomato Leafminer, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ak%C4%B1n%20Kuyulu">Akın Kuyulu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hanife%20Gen%C3%A7"> Hanife Genç</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In present study, it was aimed to evaluate the gamma radiation impacts on tomato leaf miner at different biological stages. The laboratory colony of tomato leaf miner was used to set up the experiments. Different biological stages of the insects (eggs, 4<sup>th</sup> instars and pupae) were irradiated using Cobalt-60 at doses of 0 (control), 100 Gray (Gy), 200 Gy, 300 Gy and 400 Gy in Cos-44HH-N source, at dose rate of 480 Gy/h. After irradiation, the eggs were incubated until hatching; the mature larvae were reared to complete their developments. Adult emergences from irradiated pupae were also evaluated. The results showed that there were no egg hatching at all tested irradiation doses. Although, the pupal percentages of irradiated mature larvae were 54%, 15% and 8% at doses of 100 Gy, 200 Gy and 300 Gy respectively, there were no adult emergences from irradiated mature larvae. On the other hand, the adult emergences were observed from irradiated pupae, decreased as radiation doses increased along with malformed adult appearance. Male and female individuals were out crossed with laboratory reared adults. Fecundity was correlated with radiation doses. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=irradiation" title="irradiation">irradiation</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato" title=" tomato"> tomato</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato%20leafminer" title=" tomato leafminer"> tomato leafminer</a>, <a href="https://publications.waset.org/abstracts/search?q=Tuta%20absoluta" title=" Tuta absoluta"> Tuta absoluta</a> </p> <a href="https://publications.waset.org/abstracts/49275/effects-of-gamma-radiation-on-tomato-leafminer-tuta-absoluta-meyrick-lepidoptera-gelechiidae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49275.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">242</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">8571</span> Coexisting Pathology of Unruptured Ectopic Pregnancy With Concurrent Ipsilateral Dermoid Cyst: A Rare Occurrence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anne%20Nicole%20Fuentes">Anne Nicole Fuentes</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A 29 year old Gravida 1 Para 0 who presented at the hospital with a 5-week history of amenorrhea, abdominal pain and vaginal bleeding.

Due to the inherent nature of open source development, a specific set of open source software development practices has evolved. While there is an ongoing research on the topic of applicability of open source development practices within a company setting, still little is known about their benefits and challenges. The objective of this research is to understand if and to what degree open source development practices observed within a mature open source community are aligned with development practices within a large software and hardware company setting. For the purpose of this case study a set of open source development practices that are present in a mature open source community has been identified. Then, development practices of a large, international, hardware and software company based in Sweden were assessed and compared to the identified open source community practices. It is shown that there are many similarities between a mature open source community and a large company setting in regard to software development practices. We also identify practices that exist in open source communities and that are not standard within a company setting, but whose implementation can result in an improved software development efficiency within the company setting. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=development%20practices" title="development practices">development practices</a>, <a href="https://publications.waset.org/abstracts/search?q=open%20source%20software" title=" open source software"> open source software</a>, <a href="https://publications.waset.org/abstracts/search?q=innersource" title=" innersource"> innersource</a>, <a href="https://publications.waset.org/abstracts/search?q=closed%20open%20source" title=" closed open source"> closed open source</a> </p> <a href="https://publications.waset.org/abstracts/13154/a-case-study-of-open-source-development-practices-within-a-large-company-setting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13154.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">558</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">8569</span> In vitro α-Amylase and α-Glucosidase Inhibitory Activities of Bitter Melon (Momordica charantia) with Different Stage of Maturity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20S.%20Percin">P.

Karakaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Bitter melon (Momordica charantia) is a medicinal vegetable, which is used traditionally to remedy diabetes. Bitter melon contains several classes of primary and secondary metabolites. In traditional Turkish medicine bitter melon is used for wound healing and treatment of peptic ulcers. Nowadays, bitter melon is used for the treatment of diabetes and ulcerative colitis in many countries. The main constituents of bitter melon, which are responsible for the anti-diabetic effects, are triterpene, protein, steroid, alkaloid and phenolic compounds. In this study total phenolics, total carotenoids and β-carotene contents of mature and immature bitter melons were determined. In addition, in vitro α-amylase and α-glucosidase activities of mature and immature bitter melons were studied. Total phenolic contents of immature and mature bitter melon were 74 and 123 mg CE/g bitter melon respectively. Although total phenolics of mature bitter melon was higher than that of immature bitter melon, this difference was not found statistically significant (p > 0.05). Carotenoids, a diverse group of more than 600 naturally occurring red, orange and yellow pigments, play important roles in many physiological processes both in plants and humans. The total carotenoid content of mature bitter melon was 4.36 fold higher than the total carotenoid content of immature bitter melon. The compounds that have hypoglycaemic effect of bitter melon are steroidal saponins known as charantin, insulin-like peptides and alkaloids. α-Amylase is one of the main enzymes in human that is responsible for the breakdown of starch to more simple sugars. Therefore, the inhibitors of this enzyme can delay the carbohydrate digestion and reduce the rate of glucose absorption. The immature bitter melon extract showed α-amylase and α-glucosidase inhibitory activities in vitro. α-Amylase inhibitory activity was higher than that of α-glucosidase inhibitory activity when IC50 values were compared.

The paleo-tectonic units in the area show some similarities with equivalent facies in Mediterranean Sea and Sicilian. The Bou Dabbous Formation displays variable source rock characteristics through the various units Tellian and Numidian nappes Units. Organic matter contents and petroleum potentials are fair to high (reaching 1.95% and 6 kg of HC/t of rock respectively) marine type II kerogen. An increasing SE-NW maturity gradient is well documented in the study area. The Bou Dabbous organic-rich facies are marginally mature stage in the Tellian Unit (Kasseb domain), whilst they are mature-late mature stage within Nefza-Ain Allega tectonic windows. A long and north of Cap Serrat-Ghardimaou Master Fault these facies are overmature. Oil/Oil and Oil/source rock correlation, based on biomarker and carbon isotopic composition, shows a positive genetic correlation between the oil seeps and Bou Dabbous source rock. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomarkers" title="biomarkers">biomarkers</a>, <a href="https://publications.waset.org/abstracts/search?q=Bou%20Dabbous%20Formation" title=" Bou Dabbous Formation"> Bou Dabbous Formation</a>, <a href="https://publications.waset.org/abstracts/search?q=Northern%20Tunisia" title=" Northern Tunisia"> Northern Tunisia</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20rock" title=" source rock"> source rock</a> </p> <a href="https://publications.waset.org/abstracts/23721/geochemical-characterization-of-bou-dabbous-formation-in-thrust-belt-zones-northern-tunisia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23721.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">485</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">8567</span> Identification of Tissue-Specific Transcription Factors in C. roseus with Emphasis to the TIA Biosynthetic Pathway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20M.%20El-Domyati">F.

A number of 290 TF-like transcripts along with 12 transcripts related to TIA biosynthetic pathway were divided in terms of co-expression in the different tissues, treatments and genotypes. Three transcripts encoding peroxidases 1 and 12 were downregulated in hairy root, while upregulated in mature leaf. Eight different transcripts of the TIA pathway co-expressed with TFs either functioning downstream tryptophan biosynthesis, e.g., tdc, str1 and sgd, or upstream vindoline biosynthesis, e.g., t16h, omt, nmt, d4h and dat. The results showed no differential expression of TF transcripts in hairy roots knocked down for tdc gene (TDCi) as compared to their wild type controls. There were several evidences of tissue-specific expression of TF transcripts in flower, mature leaf, root/hairy root, stem, seedling, hairy root and immature/mature leaves. Regulation included transcription factor families, e.g., bHLH, MYB and WRKY mostly induced by ABA and/or JA (or MeJA) and regulated during abiotic or biotic stress. The information of tissue-specific regulation and co-expression of TFs and genes in the TIA pathway can be utilized in manipulating alkaloid biosynthesis in C. roseus. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SRA%20database" title="SRA database">SRA database</a>, <a href="https://publications.waset.org/abstracts/search?q=bHLH" title=" bHLH"> bHLH</a>, <a href="https://publications.waset.org/abstracts/search?q=MYB" title=" MYB"> MYB</a>, <a href="https://publications.waset.org/abstracts/search?q=WRKY" title=" WRKY"> WRKY</a>, <a href="https://publications.waset.org/abstracts/search?q=co-expression" title=" co-expression "> co-expression </a> </p> <a href="https://publications.waset.org/abstracts/42512/identification-of-tissue-specific-transcription-factors-in-c-roseus-with-emphasis-to-the-tia-biosynthetic-pathway" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42512.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">420</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">8566</span> Phytochemical Screening, Antimicrobial and Antioxidant Efficacy of the Endocarps Fruits of Argania spinosa (L.)

However, it is a recognised oil, forage, and timber tree highly adapted to aridity. The exploitation of the argan fruits produces considerable amounts of under or related products. These products, such as the endocarps of a fruit, recuperated after the use of kernels to extract oil. This research studies in detail the contents of total phenolic content was determined by Folin Ciocalteu reagent and Flavonoids by aluminum chloride colorimetric assay). Antioxidant activity of extracts was expressed as the percentage of DPPH radical inhibition and IC50 values (μg/mL). Antimicrobial activity evaluated using agar disk diffusion method against reference Pseudomonas aeruginosa ATTC 27453, Escherichia coli ATCC 23922. Immature endocarps showed a higher polyphenol content than mature endocarps. The total phenolic content in immature endocarps was found to vary from 983,75+ /- 0.45 to 980,1 +/- 0.43 mg gallic acid equivalents/g dry weight, whereas in mature endocarps, the polyphenol content ranged from 100,58 mg/g +/- 0.42 to 105 +/- 0.55% mg gallic acid equivalent / g dry weight. The flavonoid content was 16.5 mg equivalent catechin/g dry weight and 9.81mg equivalent catechin /g dry weight for immature and mature endocarp fruits, respectively. DPPH assay of the endocarps extract yielded a half-maximal effective concentration (IC50) value in the immature endocarps (549.33 μg/mL) than in mature endocarps (322 μg/mL). This result can be attributed to the higher phenolics and flavonoid compounds in the immature endocarps. Methanol extract of immature endocarps exhibited antibacterial activity against E.colie (inhibition zone, 11mm). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title="antioxidant activity">antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=antimicrobial%20activity" title=" antimicrobial activity"> antimicrobial activity</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20phenolic%20content" title=" total phenolic content"> total phenolic content</a>, <a href="https://publications.waset.org/abstracts/search?q=DPPH%20assay" title=" DPPH assay"> DPPH assay</a> </p> <a href="https://publications.waset.org/abstracts/150574/phytochemical-screening-antimicrobial-and-antioxidant-efficacy-of-the-endocarps-fruits-of-argania-spinosa-l-skeels-sapotaceae-in-mostaganem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150574.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">117</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8565</span> Factors Afecting the Academic Performance of In-Service Students in Science Educaction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Foster%20Chilufya">Foster Chilufya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study sought to determine factors that affect academic performance of mature age students in Science Education at University of Zambia. It was guided by Maslow’s Hierarchy of Needs. The theory provided relationship between achievement motivation and academic performance. A descriptive research design was used. Both Qualitative and Quantitative research methods were used to collect data from 88 respondents. Simple random and purposive sampling procedures were used to collect from the respondents. Concerning factors that motivate mature-age students to choose Science Education Programs, the following were cited: need for self-actualization, acquisition of new knowledge, encouragement from friends and family members, good performance at high school and diploma level, love for the sciences, prestige and desire to be promoted at places of work. As regards factors that affected the academic performance of mature-age students, both negative and positive factors were identified. These included: demographic factors such as age and gender, psychological characteristics such as motivation and preparedness to learn, self-set goals, self esteem, ability, confidence and persistence, student prior academic performance at high school and college level, social factors, institutional factors and the outcomes of the learning process. In order to address the factors that negatively affect academic performance of mature-age students, the following measures were identified: encouraging group discussions, encouraging interactive learning process, providing a conducive learning environment, reviewing Science Education curriculum and providing adequate learning materials. Based on these factors, it is recommended that, the School of Education introduces a program in Science Education specifically for students training to be teachers of science. Additionally, introduce majors in Physics Education, Biology Education, Chemistry Education and Mathematics Education relevant to what is taught in high schools. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=academic" title="academic">academic</a>, <a href="https://publications.waset.org/abstracts/search?q=performance" title=" performance"> performance</a>, <a href="https://publications.waset.org/abstracts/search?q=in-service" title=" in-service"> in-service</a>, <a href="https://publications.waset.org/abstracts/search?q=science" title=" science"> science</a> </p> <a href="https://publications.waset.org/abstracts/17715/factors-afecting-the-academic-performance-of-in-service-students-in-science-educaction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17715.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">311</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">8564</span> Rheometer Enabled Study of Tissue/biomaterial Frequency-Dependent Properties</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Polina%20Prokopovich">Polina Prokopovich</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Despite the well-established dependence of cartilage mechanical properties on the frequency of the applied load, most research in the field is carried out in either load-free or constant load conditions because of the complexity of the equipment required for the determination of time-dependent properties. These simpler analyses provide a limited representation of cartilage properties thus greatly reducing the impact of the information gathered hindering the understanding of the mechanisms involved in this tissue replacement, development and pathology. More complex techniques could represent better investigative methods, but their uptake in cartilage research is limited by the highly specialised training required and cost of the equipment. There is, therefore, a clear need for alternative experimental approaches to cartilage testing to be deployed in research and clinical settings using more user-friendly and financial accessible devices. Frequency dependent material properties can be determined through rheometry that is an easy to use requiring a relatively inexpensive device; we present how a commercial rheometer can be adapted to determine the viscoelastic properties of articular cartilage. Frequency-sweep tests were run at various applied normal loads on immature, mature and trypsinased (as model of osteoarthritis) cartilage samples to determine the dynamic shear moduli (G*, G′ G″) of the tissues. Moduli increased with increasing frequency and applied load; mature cartilage had generally the highest moduli and GAG depleted samples the lowest. Hydraulic permeability (KH) was estimated from the rheological data and decreased with applied load; GAG depleted cartilage exhibited higher hydraulic permeability than either immature or mature tissues. The rheometer-based methodology developed was validated by the close comparison of the rheometer-obtained cartilage characteristics (G*, G′, G″, KH) with results obtained with more complex testing techniques available in literature. Rheometry is relatively simpler and does not require highly capital intensive machinery and staff training is more accessible; thus the use of a rheometer would represent a cost-effective approach for the determination of frequency-dependent properties of cartilage for more comprehensive and impactful results for both healthcare professional and R&D. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tissue" title="tissue">tissue</a>, <a href="https://publications.waset.org/abstracts/search?q=rheometer" title=" rheometer"> rheometer</a>, <a href="https://publications.waset.org/abstracts/search?q=biomaterial" title=" biomaterial"> biomaterial</a>, <a href="https://publications.waset.org/abstracts/search?q=cartilage" title=" cartilage"> cartilage</a> </p> <a href="https://publications.waset.org/abstracts/168024/rheometer-enabled-study-of-tissuebiomaterial-frequency-dependent-properties" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168024.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">81</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">8563</span> Shale Gas Accumulation of Over-Mature Cambrian Niutitang Formation Shale in Structure-Complicated Area, Southeastern Margin of Upper Yangtze, China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chao%20Yang">Chao Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jinchuan%20Zhang"> Jinchuan Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yongqiang%20Xiong"> Yongqiang Xiong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Lower Cambrian Niutitang Formation shale (NFS) deposited in the marine deep-shelf environment in Southeast Upper Yangtze (SUY), possess excellent source rock basis for shale gas generation, however, it is currently challenged by being over-mature with strong tectonic deformations, leading to much uncertainty of gas-bearing potential. With emphasis on the shale gas enrichment of the NFS, analyses were made based on the regional gas-bearing differences obtained from field gas-desorption testing of 18 geological survey wells across the study area. Results show that the NFS bears low gas content of 0.2-2.5 m³/t, and the eastern region of SUY is higher than the western region in gas content. Moreover, the methane fraction also presents the similar regional differentiation with the western region less than 10 vol.% while the eastern region generally more than 70 vol.%. Through the analysis of geological theory, the following conclusions are drawn: Depositional environment determines the gas-enriching zones. In the western region, the Dengying Formation underlying the NFS in unconformity contact was mainly plateau facies dolomite with caves and thereby bears poor gas-sealing ability. Whereas the Laobao Formation underling the NFS in eastern region was a set of siliceous rocks of shelf-slope facies, which can effectively prevent the shale gas from escaping away from the NFS. The tectonic conditions control the gas-enriching bands in the SUY, which is located in the fold zones formed by the thrust of the Southern China plate towards to the Sichuan Basin. Compared with the western region located in the trough-like folds, the eastern region at the fold-thrust belts was uplifted early and deformed weakly, resulting in the relatively less mature level and relatively slight tectonic deformation of the NFS. Faults determine whether shale gas can be accumulated in large scale. Four deep and large normal faults in the study area cut through the Niutitang Formation to the Sinian strata, directly causing a large spillover of natural gas in the adjacent areas. For the secondary faults developed within the shale formation, the reverse faults generally have a positive influence on the shale accumulation while the normal faults perform the opposite influence. Overall, shale gas enrichment targets of the NFS, are the areas with certain thickness of siliceous rocks at the basement of the Niutitang Formation, and near the margin of the paleouplift with less developed faults. These findings provide direction for shale gas exploration in South China, and also provide references for the areas with similar geological conditions all over the world. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=over-mature%20marine%20shale" title="over-mature marine shale">over-mature marine shale</a>, <a href="https://publications.waset.org/abstracts/search?q=shale%20gas%20accumulation" title=" shale gas accumulation"> shale gas accumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=structure-complicated%20area" title=" structure-complicated area"> structure-complicated area</a>, <a href="https://publications.waset.org/abstracts/search?q=Southeast%20Upper%20Yangtze" title=" Southeast Upper Yangtze"> Southeast Upper Yangtze</a> </p> <a href="https://publications.waset.org/abstracts/93424/shale-gas-accumulation-of-over-mature-cambrian-niutitang-formation-shale-in-structure-complicated-area-southeastern-margin-of-upper-yangtze-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93424.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">147</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">8562</span> Renewable Energy Trends Analysis: A Patents Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sepulveda%20Juan">Sepulveda Juan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This article explains the elements and considerations taken into account when implementing and applying patent evaluation and scientometric study in the identifications of technology trends, and the tools that led to the implementation of a software application for patent revision.

Researches have been developed with the objective of conserving the biological material of this species. We evaluated the cooling of mature oocytes in the cryoprotective solutions containing the following alcohols: methanol, Propylene glycol and DMSO, each at concentrations of 1M, 2M and 4M, totaling nine treatments. After being submitted to treatments, the oocytes were maintained for 120 minutes in cooling to -5.52±2.58⁰C. A sample of oocytes was submitted to negative control (NC), kept in 90% L-15 solution, and positive control (PC), fertilized and taken directly to the incubator. Fertilization and hatching rates were evaluated. In order to compare the sensitivity of oocytes to embryos of the same species, the embryos maintained as CP in the previous assay were used in the free-flow stage (about 22 hours post fertilization) and submitted to the same treatments (prepared in distilled water) and also cooled for 120 min. The evaluation was done by the hatch rate. There was no fertilization rate of the oocytes submitted to the cooling with propylene glycol; the other cryoprotectants presented values of at most 3.7% of fertilization (Methanol 1M), and no treatment completed development until hatching. The cooled embryos had a significant percentage of normal larvae in all treatments, but inversely proportional to the increase in the concentration of the alcohols. DMSO 1M was the most promising treatment for embryo cooling, with 41.7% ± 20.2 of normal larvae, while mature oocytes were highly sensitive to cold. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryoconservation" title="cryoconservation">cryoconservation</a>, <a href="https://publications.waset.org/abstracts/search?q=cooling" title=" cooling"> cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=embryos" title=" embryos"> embryos</a>, <a href="https://publications.waset.org/abstracts/search?q=freezing" title=" freezing"> freezing</a>, <a href="https://publications.waset.org/abstracts/search?q=oocytes" title=" oocytes"> oocytes</a>, <a href="https://publications.waset.org/abstracts/search?q=south%20American%20fish" title=" south American fish"> south American fish</a> </p> <a href="https://publications.waset.org/abstracts/72601/sensitivity-of-steindachneridion-parahybae-mature-oocytes-versus-embryos-at-low-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72601.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">241</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">8560</span> Borassus aethiopum Mart Mature Fruits Macro-Composition, Drying Temperature Effect on Its Pulp Protein, Fat, Sugars, Metabolizable Energy, and Fatty Acids Profile</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tagouelbe%20Tiho">Tagouelbe Tiho</a>, <a href="https://publications.waset.org/abstracts/search?q=Amissa%20Augustin%20Adima"> Amissa Augustin Adima</a>, <a href="https://publications.waset.org/abstracts/search?q=Yao%20Casimir%20Brou"> Yao Casimir Brou</a>, <a href="https://publications.waset.org/abstracts/search?q=Nabayo%20Traore"> Nabayo Traore</a>, <a href="https://publications.waset.org/abstracts/search?q=Gouha%20Firmin%20Kouassi"> Gouha Firmin Kouassi</a>, <a href="https://publications.waset.org/abstracts/search?q=Thierry%20Roland%20Kouame"> Thierry Roland Kouame</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryline%20Kouba"> Maryline Kouba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The work aimed to study Borassus aethiopum Mart (B.a) dried pulp nutritional value for its incorporation in human and poultry diets. Firstly, the mature fruit macro-composition was assessed. Secondly, the pulp was dried at 40, 50, 60, 70, and 80ᵒC. Thereafter, the analysis was performed for fat, protein, total sugars, Ca, P, Mg, and fatty acid profile monitoring. As a result, the fruits weighed 1,591.35, delivered 516.73, and 677.82 grams of pulp and seeds, respectively. Mainly, increasing heat adversely affected the outputs. Consequently, the fat results were 14.12, 12.97, 8.93, 8.89ᶜ, and 5.56%; protein contents were 11.64, 10.15, 8.97, 8.84, and 8.42%; total sugar deliveries were 6.28, 6.05, 5.26, 5.02, and 4.76% (P < 0.01). Thereafter, the metabolizable energies were 3,785.22; 3,834.28; 3,616.62; 3,667.03; and 3,608.33 kcal/kg (DM). Additionally, Calcium (Ca) contents were 0.51, 0.55, 0.69, 0.77, and 0.81%, while phosphorus (P) mean was 0.17%, and the differences were not significant (P < 0.01). So, the Ca/P ratios were 2.79, 3.04, 4.10, 4.71, and 4.95. Finally, fatty acids (FA) assessments revealed 22.33 saturated (SFA), 77.67 unsaturated (UFA), within which 67.59% were monounsaturated (MUFA). Interestingly, the rising heat depressed n-6/n-3 ratios that were 1.1, 1.1, 0.45 and 0.38, respectively at 40, 50, 70 and 80ᵒC. In short, drying did not only enhance the product shelf life but it also improved the nutritional value. Thus, B.a mature fruit pulps dried at 70ᵒC are good functional foods, with more than 66% MUFA, and energy source for human and poultry nutrition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Borassus%20aethiopum%20Mart" title="Borassus aethiopum Mart">Borassus aethiopum Mart</a>, <a href="https://publications.waset.org/abstracts/search?q=fatty%20acids" title=" fatty acids"> fatty acids</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolizable%20energy" title=" metabolizable energy"> metabolizable energy</a>, <a href="https://publications.waset.org/abstracts/search?q=minerals" title=" minerals"> minerals</a>, <a href="https://publications.waset.org/abstracts/search?q=protein" title=" protein"> protein</a> </p> <a href="https://publications.waset.org/abstracts/91972/borassus-aethiopum-mart-mature-fruits-macro-composition-drying-temperature-effect-on-its-pulp-protein-fat-sugars-metabolizable-energy-and-fatty-acids-profile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91972.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">8559</span> Assessment of Germination Loss Due to Dusky Cotton Bug (Oxycarenus laetus) in Relation to Cotton Boll Stage and Bug Intensity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Hassan">Ali Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Mian%20Muhammad%20Awais"> Mian Muhammad Awais</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Rafique%20Shahid"> Muhammad Rafique Shahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Farazia%20Hassan"> Farazia Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Shumaila%20%20Rasool"> Shumaila Rasool</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dusky cotton bug (Oxycarenus laetus) has attained the status of major insect pest of cotton. It is also known as seed bug due to its property of feeding on seeds. It causes floral abscission at flowering stage and reduction in seed germination. Present study was carried out to assess germination loss caused by dusky bug with respect to crop stage and insect intensity. Treatments consisted of three stages immature boll, mature boll and opened boll as well three levels of dusky bug i.e., 50 bugs per boll, 40 bugs per boll along with zero level kept as control. Results showed that the germination percentage was highest in control treatment where no insect was released followed by treatment where 40 insects released and minimum germination showed by treatment in which 50 insects were released. The germination percentage of seeds surpassed after control treatment in the treatment where dusky bugs exposure was given at boll opening stage than on mature boll stage. Minimum germination was observed in immature boll stage. Interaction between crop stages and dusky bug levels showed that germination percentage of seeds was maximum in control treatment then boll opening stage followed by mature boll stage. Minimum seed germination was recorded in dusky bug treatment at immature boll stage which was 34% where 50 insects were released. From the results it is clear that dusky bug should be managed properly at all reproductive stages but immature stage is most critical. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gossypium%20hirsutum" title="Gossypium hirsutum">Gossypium hirsutum</a>, <a href="https://publications.waset.org/abstracts/search?q=Oxycarenus%20laetus" title=" Oxycarenus laetus"> Oxycarenus laetus</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20bug" title=" seed bug"> seed bug</a>, <a href="https://publications.waset.org/abstracts/search?q=seed%20germination" title=" seed germination"> seed germination</a> </p> <a href="https://publications.waset.org/abstracts/72297/assessment-of-germination-loss-due-to-dusky-cotton-bug-oxycarenus-laetus-in-relation-to-cotton-boll-stage-and-bug-intensity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72297.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">324</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">8558</span> A Review of Protocols and Guidelines Addressing the Exposure of Occupants to Electromagnetic Field (EMF) Radiation in Buildings </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shabnam%20Monadizadeh">Shabnam Monadizadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Charles%20Kibert"> Charles Kibert</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiaxuan%20Li"> Jiaxuan Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Janghoon%20Woo"> Janghoon Woo</a>, <a href="https://publications.waset.org/abstracts/search?q=Ashish%20Asutosh"> Ashish Asutosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Samira%20Roostaei"> Samira Roostaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Kouhirostami"> Maryam Kouhirostami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A significant share of the technology that has emerged over the past several decades produces electromagnetic field (EMF) radiation. Communications devices, household appliances, industrial equipment, and medical devices all produce EMF radiation with a variety of frequencies, strengths, and ranges. Some EMF radiation, such as Extremely Low Frequency (ELF), Radio Frequency (RF), and the ionizing range have been shown to have harmful effects on human health. Depending on the frequency and strength of the radiation, EMF radiation can have health effects at the cellular level as well as at brain, nervous, and cardiovascular levels. Health authorities have enacted regulations locally and globally to set critical values to limit the adverse effects of EMF radiation. By introducing a more comprehensive field of EMF radiation study and practice, architects and designers can design for a safer electromagnetic (EM) indoor environment, and, as building and construction specialists, will be able to monitor and reduce EM radiation. This paper identifies the nature of EMF radiation in the built environment, the various EMF radiation sources, and its human health effects. It addresses European and US regulations for EMF radiation in buildings and provides a preliminary action plan. The challenges of developing measurement protocols for the various EMF radiation frequency ranges and determining the effects of EMF radiation on building occupants are discussed. This paper argues that a mature method for measuring EMF radiation in building environments and linking these measurements to human health impacts occupant health should be developed to provide adequate safeguards for human occupants of buildings for future research. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biological%20affection" title="biological affection">biological affection</a>, <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20field" title=" electromagnetic field"> electromagnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20regulation" title=" building regulation"> building regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20health" title=" human health"> human health</a>, <a href="https://publications.waset.org/abstracts/search?q=healthy%20building" title=" healthy building"> healthy building</a>, <a href="https://publications.waset.org/abstracts/search?q=clean%20construction" title=" clean construction "> clean construction </a> </p> <a href="https://publications.waset.org/abstracts/129637/a-review-of-protocols-and-guidelines-addressing-the-exposure-of-occupants-to-electromagnetic-field-emf-radiation-in-buildings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/129637.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">181</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">8557</span> Mature Field Rejuvenation Using Hydraulic Fracturing: A Case Study of Tight Mature Oilfield with Reveal Simulator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amir%20Gharavi">Amir Gharavi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hassan"> Mohamed Hassan</a>, <a href="https://publications.waset.org/abstracts/search?q=Amjad%20Shah"> Amjad Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main characteristics of unconventional reservoirs include low-to ultra low permeability and low-to-moderate porosity. As a result, hydrocarbon production from these reservoirs requires different extraction technologies than from conventional resources. An unconventional reservoir must be stimulated to produce hydrocarbons at an acceptable flow rate to recover commercial quantities of hydrocarbons. Permeability for unconventional reservoirs is mostly below 0.1 mD, and reservoirs with permeability above 0.1 mD are generally considered to be conventional. The hydrocarbon held in these formations naturally will not move towards producing wells at economic rates without aid from hydraulic fracturing which is the only technique to assess these tight reservoir productions. Horizontal well with multi-stage fracking is the key technique to maximize stimulated reservoir volume and achieve commercial production. The main objective of this research paper is to investigate development options for a tight mature oilfield. This includes multistage hydraulic fracturing and spacing by building of reservoir models in the Reveal simulator to model potential development options based on sidetracking the existing vertical well. To simulate potential options, reservoir models have been built in the Reveal. An existing Petrel geological model was used to build the static parts of these models. A FBHP limit of 40bars was assumed to take into account pump operating limits and to maintain the reservoir pressure above the bubble point. 300m, 600m and 900m lateral length wells were modelled, in conjunction with 4, 6 and 8 stages of fracs. Simulation results indicate that higher initial recoveries and peak oil rates are obtained with longer well lengths and also with more fracs and spacing. For a 25year forecast, the ultimate recovery ranging from 0.4% to 2.56% for 300m and 1000m laterals respectively. The 900m lateral with 8 fracs 100m spacing gave the highest peak rate of 120m3/day, with the 600m and 300m cases giving initial peak rates of 110m3/day. Similarly, recovery factor for the 900m lateral with 8 fracs and 100m spacing was the highest at 2.65% after 25 years. The corresponding values for the 300m and 600m laterals were 2.37% and 2.42%. Therefore, the study suggests that longer laterals with 8 fracs and 100m spacing provided the optimal recovery, and this design is recommended as the basis for further study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=unconventional" title="unconventional">unconventional</a>, <a href="https://publications.waset.org/abstracts/search?q=resource" title=" resource"> resource</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic" title=" hydraulic"> hydraulic</a>, <a href="https://publications.waset.org/abstracts/search?q=fracturing" title=" fracturing"> fracturing</a> </p> <a href="https://publications.waset.org/abstracts/66977/mature-field-rejuvenation-using-hydraulic-fracturing-a-case-study-of-tight-mature-oilfield-with-reveal-simulator" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66977.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">298</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">8556</span> Video Processing of a Football Game: Detecting Features of a Football Match for Automated Calculation of Statistics</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rishabh%20Beri">Rishabh Beri</a>, <a href="https://publications.waset.org/abstracts/search?q=Sahil%20Shah"> Sahil Shah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We have applied a range of filters and processing in order to extract out the various features of the football game, like the field lines of a football field.
