Journal: Journal of New Media and Mass Communication

Export to    BibTeX   |   EndNote   |   RIS

Abstract
The gradual inclusion of the participation of the public in museums through social networks and other tools that enhance the user’s leadership in the management of information and in the knowledge production seems to have led to an evolution in the cultural experience of the public. However, we do not know yet whether the possibility to intervene and manipulate the content really optimize the communication between visitors widening their possibilities of action turning them into a concerned and active audience.  In this study, we have analyzed practices and motivations of on line audience, detecting some guidelines that should be considered when incorporating user participation in heritage institutions. The analysis of when a participatory environment can encourage the dissemination of the contents of the museum and engage audiences in an ongoing and repeated relationship that encompasses even the attendance realm, was performed using a qualitative methodological perspective though supported by some quantitative data related to the profiles of the recipients of cultural activities and their practices in the network. The suggestions proposed, by virtue of being the result of an evaluation process of public preferences, would highlight the real needs of on line visitors and reduce the dissociation between the way that museums seek to use their pages and effective practices of their users. Looking at these results, this research (based on the analysis of four case studies) represents an attempt to approach the strategies adopted by the institutional sphere in relation to the new social media and to the current needs of the public.
Contribution/ Originality
This study documents the digital strategies used by museums of art and design to communicate with their audiences. The paper’s primary contribution is finding those that elicit a positive response from the general public and the factors that are linked implicitly to their success.

Abstract
The municipality of M’rirt located in the eastern part of central Morocco, in response to the scarcity of water resources in food, the national Office of Drinking Water has used the coagulation-flocculation for water treatment of Oum Errabia River, process of removing the most delicate phase in suspension by the addition of a body chemical called coagulant. The application of coagulation flocculation process for the treatment of surface water is an interesting alternative as the treatment is fast, cheap and allows obtaining perfectly clear water can fill the deficit in water. In the case of our study, we chose the coagulation-flocculation with aluminum sulphate and ferric chloride in order to compare their effectiveness in the elimination or reduction of turbidity on the one hand, and On the other hand see the effectiveness of aluminum sulfate in an acid pH range. The tests are performed in the laboratory and were conducted using a jar test. Ferric chloride showed an effective reduction of the turbidity of water from the aluminum sulfate at low concentrations. The reduction in turbidity of the water by the aluminum sulphate is higher in acid pH (pH 5.5) according to the results obtained from the tests.

Abstract
This study was conducted on stations and on farm in three districts of South region, Ethiopia, to evaluate the lentil varieties for yield and adaptation, assess farmer’s preferences during 2004/05 Meher Season. Data on plant height, hundred seed weight, pod per plant, days to flowering, days to maturity and grain yield were collected. Six lentil varieties which included five released and one local check of respective locations were planted on 3.2m2 plots at spacing of 20cm* 2cm.  The plots consisted of four rows which were four meters long for on-centre and on farm trials. The trials were laid in randomized complete block design with four replications. Twelve farmers from three districts of four farmers at each village were participated in executing on farm trials. Each farmer was a replicate for on farm component. There were significant differences among varieties for grain yield and some of traits. The results for the on-centre and on farm trials indicated that there were significant yield differences between the local check and the released varieties at two stations and three districts. The varieties Teshale and Alemaya were superior yielded overall to the local check across three villages ’and on stations. Thus, Alemaya and Teshale out yielded other varieties and had average yields of 1239.1 kg/ha and 1193.8 kg/ha at on station and 1165.1 kg/ha and 1202kg/ha at on farm trials, respectively. Combined statistical analysis and farmers assessments identified two genotypes (Teshale and Alemaya) as potential varieties for production in south Ethiopia. Therefore, based on researchers and farmers’ preference, varieties Teshale and Alemaya are recommended for production in Lemu, Gumur and Damot Gale districts and similar agro ecologies of south Ethiopia.

Abstract
The African ebony (Dalbergia melanoxylon) is a tree that is crucial in making of high value wooden traditional artifacts, however its slow growth in the arid and semi-arid lands (ASALs), poor germination and low seedling growth rate, seed pest predation coupled with overharvesting pause a great threat for the future availability of the species. Unscreened natural methods of seed germination might not sustainably solve the problem of low germination. Overharvesting for wood carving, and low natural regenerative ability of the species and lack of the local and national conservation efforts present a serious threat its availability to the future availability of Dalbergia melanoxylon. Availability of viable seed plays a crucial role the establishment of African ebony. There is need for immediate methods for multiple seedling production for propagation of D. melanoxylon. Our studies showed 2% germination without screening but increased to 40% after screening (p< 0.001). Careful moisture monitoring of the seedling seemed to increase the growth rate in the ASAL region. Therefore, selected propagation methods of this species can rescue it from the current extinction trend which is caused by its low regenerative ability when natural methods are used and over exploitation. There is need to support on farm cultivation of the tree to sustain the carving industry.

Journal: International Journal of Chemistry and Materials Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
In this work, response surface methodology (RSM) and artificial neural network (ANN) was used to optimize of oil from Sesamum indicum seeds. ANN predicted optimal condition for extraction was Sesamum indicum powder weight (SIPW) = 54.71 g, extraction time (ET) = 44.88 min and solvent volume (SV) = 165.8 mL. The predicted Sesamum indicum oil yield (SIOY) was validated as 85.70% (w/w) while RSM predicted optimal condition was Sesamum indicum powder weight (SIPW) = 60.00 g, Extraction time (ET) = 44.48 min and solvent volume (SV) = 150 mL. The predicted SIOY under this condition was validated as 83.20% (w/w). The result obtained showed that ANN was superior and more effective optimization tool than RSM owing to its value of RMSE, AAD, R2, R2Adj. Meanwhile, the qualities of Sesamum indicum oil yield (SIOY) as compared to the earlier researched works indicated that the oil produced is of good qualities and needs no further purification. Fatty acids profile reflected that the oil is highly unsaturated. The study concluded that the oil is not only edible, but also could have an industrial application.
Contribution/ Originality
The paper’s primary contribution is finding that Sesamum indicum seed is not only for food consumption but could also be used as oil source for industrial application. This study documents the supremacy of ANN over RSM.

Journal: Asian Journal of Energy Transformation and Conservation

Export to    BibTeX   |   EndNote   |   RIS

Abstract
An important feature of an electric power system is that its customer’s load varies greatly at random according to time of day, and day of season. Time-of-day pricing of electricity is an indirect load management against such variable demand according to which electricity is charged in relation to the time-differential cost of supply. The present study is an attempt at modeling seasonal time-differential pricing of electricity. The static, deterministic model that we present incorporates diverse technology, as well as soft deterministic equivalents of chance constraints representing stochastic demand and inflows. The model is solved for two types of power systems – pure hydro and hydro-thermal – under the umbrellas of four structural assumptions – first best, second-best, monopoly and constrained monopoly.
Contribution/ Originality
The present study models seasonal time-differential pricing of electricity under diverse welfare assumptions of first best, second best, monopoly and regulated monopoly pricing, in the case of two typical power systems – hydro and hydro-thermal.

Journal: Review of Energy Technologies and Policy Research

Export to    BibTeX   |   EndNote   |   RIS

Abstract
This paper presents a new efficient approach to   economic load dispatch (ELD) problem with cost functions using curve fitting, ANN and particle swarm optimization (PSO). Economic load dispatch is one of the most important problems in power system operation. The practical ELD problems may not have fixed cost functions rather it changes with the coal quality, that make the problem of finding the global optimum difficult using any traditional mathematical approach. Therefore, curve fitting technique is used to obtain the coefficients of the cost curve. The same data is used for the training of the artificial neural network. The effectiveness of the algorithm is validated by carrying out extensive test on a power system involving 8 thermal generating units. The variation in calorific values of the coal used in different generators cause the change in coefficients of cost curve. This effect is incorporated using curve fitting, ANN and PSO approaches. The ELD problem is then optimized. The comparison shows the better results.
Contribution/ Originality
This study for economic load dispatch is one of very few studies which have investigated for variation in calorific values of the coal used time to time in thermal power plants.  This uses the comparison of conventional, curve fitting, PSO and ANN.

Conjugated polymer is a molecular entity whose structure is represented as a system of alternating single and double bonds which give rise to their semi-conductor properties. Conjugated polymers are used for photovoltaic devices because, Intrinsically stable up on photoexcitation with visible light, High absorption cross-section for photon harvesting, Tunable band gap with in the entire visible spectral range and High yield of charge generation when mixed with electron acceptor materials. The important physical process in the energy conversion process that take place in polymers for photovoltaic cells are; Absorption of a photon of light by photoactive material and generation of excitons, diffusion of excitons in conjugated polymers, dissociation of charge carriers (electron-hole pair) at the donor-acceptor interface in to free carriers, transport of free carriers towards the electrodes, and extraction of the charge carriers at the respective electrode interfaces. The efficiency of converting solar to electrical energy by a solar cell depends on the band gap of the light absorbing semiconductor. Band gap (Eg) is the difference in energy between the HOMO and LUMO and there by the maximum amount of energy required for an excitation or is the energy difference between the edges of the conduction band and valence band. The power conversion efficiency is a function of band gap. For device architectures of conjugated polymer based photovoltaic cells; there are three types Single layer photovoltaic cell, Bilayer hetero junction photovoltaic cell and Bulk hetero junction Photovoltaic cell. 
Contribution/ Originality
The paper’s primary contribution is finding that introducing to the application of organic polymers for photovoltaic devices, that is the application of conjugated organic polymers in electronics or the relation between organic chemistry and electronics which in turn contributes to the investigation of new materials for environmentally friend renewable energy.

Results: Out of 576 study participants 50.3% were stunted. Stunting was 3.1times more common in households where decision was made by husband only (P=0.001), paternal education level of 7-8 grade was 2.29 times the contributing factor of stunting [AOR= 2.29, 95% CI: 1.15-4.54]. Children who did not eat vegetable source foods were 2.54 times more likely to be stunted [AOR= 2.54, 95% CI: 1.20-5.37]. Conclusion and Recommendation: Prevalence of stunting in Wondo Genet Woreda is similar when compared to the national figure and among female and male participants. Home delivery was found to be the protective factors of stunting and similar impact was seen by displacement from usual residence. Thus the community based nutrition program for prevention and early detection of stunting should be strengthened.
Contribution/ Originality
This study is the first of its kind in this study area. So it contributes for strengthening in the existing literature at national and regional level.

Abstract
It is observed in geriatric population that a variety of changes occur with aging that can impact social, physiologic and psychological well being. Most people, however, experience a decrease or complete absence in salivary flow. Salivary dysfunction in old age is a consequence of debilitating systemic diseases and related medications, head and neck radiotherapy and reduced functional reserve that detrimentally impact nutritional status and general health. This article provides an overview on salivary gland hypofunction in geriatric population, etiopathogenesis and management strategies.
Contribution/ Originality
This compilation documents the causes and treatment of xerostomia among geriatric population in a comprehensive way.

Abstract
Among the 35 Tephritidae species recorded in Togo, only Bactrocera invadens Drew, Tsuruta and White had high prevalence throughout the year and infested fruits of commercial importance. In perspective for control of B. invadens, a wild strain of this pest was reared in an open room conditions similar to those of the external medium (27.5 ± 1 ° C, 79.5 ± 3% RH and approximately 12: 12 L: D). It was fed on local diet consisting of a mixture of soya flour and superfine sugar, and water in the presence of a mango (cultivar Eldon). These conditions allowed us to determine it biological and growth parameters. Ovariole number per ovary in B. invadens was 41. The total mean development time was 21.71 ± 0.99 days. Egg incubation, larval development and puparia-adult periods were respectively 1.28 ± 0.02, 11.35 ± 1.13 and 9.37 ± 0.19 days. About 68.50 ± 5.13% of the eggs developed to the adult stage. Life expectancy at pupal eclosion was 55.03 ± 30.75 days in males and 51.94 ± 21.03 in females. Average fecundity and fertility rates were respectively 535.74 ± 235.70 eggs and 92.67 ± 4.68%. Net reproductive rate and intrinsic rate of population increase were respectively 98.50 females per female and 10% per day. These results summarized the life-history of B. invadens in Guinean zone condition and are useful for assessment of demographic parameters of natural enemies of this insect in perspective of an efficient and sustainable management of its populations.
Contribution/ Originality
This study is one of very few studies which have investigated reproductive and development of an invasive alien species B. invadens in a local condition in Africa. Then, the demographic parameters that are important for control strategies were determined.
