Applying Active Dynamic Signage System in Complex Underground Construction[ ]


In the event of emergency evacuations in large-scale public buildings, the complexity and capacity of the building are factors that prolong the egress time for the public and hinder the management of the risks pertinent to the evacuation route. Therefore, improving the effectiveness of a signage system for emergency evacuation is crucial. A previous study which was designated by E.R. Galea, developed an Active Dynamic Signage System for directing people toward safety exits according to the surrounding environment. In this study, we used the Dr.Galea’sprevious experimental result of different signage systems as the basis for setting the parameters of an evacuation simulation software program. After verifying the consistency of the simulation and previous experimental results, we applied the same parameter configuration to a more complex setting and simulated the smoke spread situation by using Fire Dynamics Simulator. This study investigated the difference between conventional signage systemsand Active Dynamic Signage System. Given that the origin of the fire is at the same point, we also examined the effectiveness of these two systems in evacuating people through different emergency exists and their effect on the safety of the evacuees.

Magnetic nanoparticles covalently functionalized with oleoyl chloride[ ]


In this work, different conditions for the synthesis of magnetic iron oxide nanoparticles (P) covalent functionalized are presented. These modifications were made in order to fix the magnetic material in an organic matrix by copolymerization reaction. A simple strategy of acid chloride chemistry for the modification of nanoparticles surface (FPi) is proposed. The process includes an ultrasound-supported addition in non-aqueous media to obtain iron oxide nanoparticles with organic chains covalently bonded to its surface coated. The structure and morphology of the prepared P and composite materials were characterized by transmission electron microscopy (TEM), x-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and the thermal stability (TG). The magnetic functionalized nanoparticles (FPi) can be easily included in a co-polymerization with styrene to prepare composite materials (FPi-PS). Morphological analysis of these composites confirms a homogeneous dispersion of the function-alized nanoparticles attached to the organic matrix.

Economic Evaluation of Micro-Grid System (On/Off Grid): Egyptian Case Study[ ]


The basic objective of this study is to reach the optimal sizes of micro-grid components, investigating technical and economic performance, taking into consideration the environmental impacts. In the intended case study, the proposed micro grid supplies two small factories; installed in a farm as a case study, with electricity, both on-grid and off-grid modes are investigated. The micro-grid comprises wind turbines, photovoltaic modules, and diesel generator and battery bank. The electrical energy generated from the micro-grid required to cover the estimated load pattern; with a peak of 76 kW, of the applied case study. To evaluate system economy two criteria are used; the net present cost and the cost of generated electricity. The sustainability of supplying the load is an indicator of the system technical performance measured by the percentage of power shortage. The most feasible system components for the selected application are obtained; based on required parameters, using HOMER simulation package. The results showed that Wind/Photovoltaic (W/PV) on-grid system is more economic than Wind/Photovoltaic/Diesel/Battery (W/PV/D/B) off-grid system as the cost of generated electricity in case of on-grid is 0.266 $/kWh while the second is 0.316 $/kWh. Taking into consideration the cost of Carbon Dioxide (CO2) emissions, the off-grid system will be competitive to the on-grid and more economic than diesel generators (DG) system as the calculated cost of energy is found to be (0.266, 0.257 and 0.345$/kWh), for grid connected, off grid, and diesel systems. Some of the previously reviewed studies discussed stand alone Renewable Energy (RE) micro-grid and others investigated grid connected system. But none of the reviewed papers compared between the two cases; on-grid and off-grid ''RE micro-grid systems''. The current study presents the comparison between the two cases from an economic point of view.

Groundwater Potential Mapping using Remote Sensing and GIS in Rift Valley Lakes Basin, Weito Sub Basin, Ethiopia[ ]


Conventional groundwater exploration methods, though they deliver higher quality results of varied scale, tend to be time consuming and expensive endeavors. The use of remotely sensed data and geographic information systems opens up the possibility to harness information of vast spatial and temporal scale, analyze, and manage it efficiently. In this paper, remotely sensed data along with geologic maps and discrete rainfall data are used to develop groundwater potential map for Weito watershed in the rift valley lake basin(RVLB) in Ethiopia. Thematic layers of rainfall, land use, slope, soil, lithology, drainage, lineament and geomorphology were developed. PCI Geomatica software is used for land use classification and lineament extraction from Landsat 8 OLI/TIRS multispectral images. ArcGIS 10.0 and its extensions are used to develop slope and geomorphologic maps from SRTM 30m DEM and digitize existing geologic maps. Soil data from ISRIC’s soilgrids database at 250m resolution for the top 200cm is used to develop soil map for the watershed. Weights are assigned to the layers using analytical hierarchy process (AHP) and overlay analysis in ArchGis used to develop the groundwater potential map. The results show 1, 15 and 23 per cent of the watershed classified as excellent, very good or good respectively, while the remaining 60 per cent of the land area is either poor or very poor groundwater potential.

Plant communities in the vicinity of the industrial areas of Korangi and Landhi in Karachi, Pakistan[ ]


Phytosociological studies were carried in the verge of Korangi and Landhi industrial locations of Karachi. The vegetation was herbaceous, shrubs and principally dispersed in character. Fifteen plant communities focused on the composition, structure and distribution of species were determined. Most of the plant communities in the proximity of industrial zones had low number of plant species as compared to less polluted site of Karachi University Campus. Highest numbers of species were recorded in Abutilon and Amaranthus-Prosopis communities around industrial regions, whereas Salsola community had particularly reduced species numbers. Importance value index of whole the species were calculated and eleven leading dominant species were recognized in the industrial areas. Abutilon indicum (L.) Sweet, Corchorus trilocularis L., Corchorus depressus (L.) Stocks and Prosopis juliflora Swartz were found in noticeable number in the communities. A. indicum had strong association with Corchorus spp, P. juliflora and Tribulus terrestris L. at Industrial sites. P. juliflora were representing well connection with Heliotropium ophioglossum Boiss, Orygia decumbens Forssk, Chloris barbata Sw., Trianthema portulacastrum L. at Karachi University site. Therefore, it is observed that A. indicum was markedly dominant plant species in the surrounding of industrial estates while P. juliflora was particularly dominant species at the University Campus.

Observing the Universe through colors (blue and red shift)[ ]


Sunsets are represented as the events of particular beauty, because one can in a short period of time see all of the spectrum colors, with red always at the end. The covering of Earth, or atmosphere, acts like a prism. The colors change due to the curvature of Earth and its atmosphere, too, and because of the length of passing through the prism (also, Sun and Moon appear to be at their full size at sunrise and sunset). The longest wave passing through the atmosphere, which results in the lowest intensity or force of the waves, produces beautiful nuances of red. This occurrence takes place both in the morning and in the evening, therefore the Doppler effect as the only explanation can be ruled out, because in the mornings there is a decrease of distance, which is the situation opposite to the one, occurring in the evenings.

Agricultural Zones Change and Availability of Food Crops on the Plateau of Allada in South-Benin[ ]


The goal of this survey is to understand the evolutions undergone by the agricultural zones of the plateau of Allada between 2002 and 2014 in the perspective of a sustainable agriculture. This geomorphologic space of Benin, with a surface of 2,037 km2, welcome a population of 717,813 inhabitants in 2013, either a density of 352 habitants/km2. The agricultural production is essentially rainfed. It is taking more and more space. Then, it is convenient to analyze the rhythm of extension to help towards consequent decision making. Thus, the landsat satellite images ETM+ 2002 and OLI 2014 have been used. They are completed by the topographic map, sector of Porto-Novo. By analyzing the results, the agricultural spaces of the plateau of Allada occupied a surface of 144,332 ha in 2014, either 71% of the hole space. It means there was a growth of 7% in comparison to 2002. 108,334 ha remained in culture or small fallow during 12 years. Therefore, about 36,000 ha constituted the result of the gains and losses on other land use units. In terms of gains, 17,629 ha of forests disappeared between 2002 and 2014 in the profit of agricultural zones. During the same period, the growth of the population had more lowered the availabilities of life crops. For example, 106 kg of available corn per inhabitant/yr in 2002 passed to 65 kg/inhabitant/yr in 2014, whereas according to the norms of the FAO, it should be of 134 kg/inhabitant/yr. then, it urges to intensify the production of food crops.

Confronting gender based violence: Gender stereotyping and its im-pact and consequences for women within the Caribbean and partic-ularly Trinidad and Tobago and the need for reform of policy and the law to afford greater protection to women[ ]


Gender based violence is a global phenomenon affecting millions of people around the world including women, men, girls and boys, however in most cases women and girls are the primary targets of such violence. The problem is particularly acute within the Caribbean and has a high prevalence rate within the context of Trinidad and Tobago where women and girls appear to be the primary targets of domestic and sexual violence. While much legislation exists on the issue of gender based violence in Trinidad and Tobago, there is a deeper need to question why such violence occurs in order to find plausible solutions to the problem which would have the overall impact of informing legislative and policy reform. There are several theories which offer a rationale for the occurrence of this problem including the social theory, the general strain theory and pro-feminist theories which offer insight into why such problems occur. However in most cases and particularly within the context of Trinidad and Tobago, such violence is often perpetrated as a result of deeply entrenched gender norms and gender stereotyping which perpetuates the problem. Confronting these gender stereotypes and gender norms is therefore critical in offering a plausible way forward in addressing this issue. Interventions suggested within this research paper therefore are focused primarily on challenging negative stereotypes on the concept of masculinity and femininity which are deeply rooted in patriarchal ways of thinking and exploring how these concepts have led to negative consequences for women, men, boys and girls and seeking to transform these concepts within society through policy and law reform.

Big-Five Personality Traits, Job Satisfaction, and Turnover Intention: A Heuristic Model for Hospital Nurses in Japan[ ]


Japanese population is rapidly ageing. Thus, there is an increased demand for nurses in Japan. However, one of the common problems in nursing is a relatively high rate of occupational withdrawal, or turnover. Past studieson personality, work attitudes, and work behaviors, although being profoundly conducted across occupations and cultures, neglected the effects of personal dispositions on turnover. Therefore, the purpose of this study is to integrate the available knowledge into one conceptual framework, by focusing on the five-factor model of personality traits, or the Big-Five, job satisfaction as one of the main work attitudes, and turnover intention, as a direct predecessor of employee withdrawal behavior. Specifically, we attempted to explain plausible direct effects the Big-Five personality traits might have on turnover intention, as well as the mediating role of job satisfaction. A tentative model is proposed and the research implications are discussed.
