Abstract
The morphology of the surface of the materials, can yield fundamental information that impacts the characteristics of the same, specifically in the process of setting of the binders that implies transformations in the density and viscosity. The objective of this work is to carry out an experimental study about the surface formation process during the setting of a cement-sand mixture, using the fractal dimension. The results showed that the experimental observations showed that the roughness and fractal dimension increased when the formation of pores occurs, likewise, the decrease of free water in the system responds to a first-order kinetics, while in the second stage It can be described through second-order kinetics. Keyword: Morphogenesis, fractal dimension, kinetics.×

Abstract
Spirulina (Arthrospira platensis), a cyanobacterium of considerable economic importance is studied for the adsorption capacity to Lead and Chromium. The cyanobacterium is very responsive to low metal concentration. The Biosorption studies showed that the algae had a great potential for adsorbing the heavy metal on to the cell. The study focuses on feasibility of the algae to be a good biosorbent. Culturing the algae in low metal concentrations can be utilized as potential tertiary treatment for metal containing effluent. The ability of Spirulina biomass to remove lead and chromium from aqueous solution was studied in batch process with respect to contact time and initial metal ions concentration at constant pH level and Biomass dosage at room temperature. The batch experiment yielded encouraging results on the potentiality of the algae to be a possible agent for removal of heavy metals from aqueous solutions.

Abstract
Refractory materials are characterized by their high melting temperature and ability to retain their properties during high temperature service operations. This study was focused on investigating the suitability of Ajaokuta Dolomite for foundry application and as a refractory material. Internationally accepted methods for testing properties of refractories were adopted and the test results were compared with acceptable standards. Beneficiated dolomite sample was also used as an additive in a moulding sand and its performance was tested by casting an aluminium pattern and comparing the result with an aluminium pattern casted using the normal foundry sand without a dolomite. Results from this study such as; Loss on ignition (39.71), flowability (34%), swelling index (0.80), mouldability (84.3%), permeability (47.3%) and porosity (29.3%) are all in conformation with the standard requirements for refractory materials. Result from the tensile test also shows that Ajaokuta dolomite can be used as an additive for foundry sand. Keyword: Aluminium, Dolomite, Refractory, Foundry.×

Abstract
This study deals with the challenges and opportunities of investment to the people of Sebeta town. Currently, countries throughout the world are intensifying investment activities in African countries. Ethiopia is one of them. The developing countries are in need of heighted investment activities for employment and income generation. Despite its positive impact pertaining to employment, investment also brings challenges to the community. The focus of this study is to investigate the challenges and opportunities of investment to the people of Sebeta town of Oromia Regional State. To achieve this objective, both primary and secondary data was used. For this purpose, informants selected from the displaced people, government officials, workers of different investment types and selected residents of the town were participants of focus group discussions, interview (semi-structured), observation and case study. In such away, 141 individuals were directly involved in this study. In anthropological studies, analysis is an instrument to extract meanings from the information obtained during the field work. In such a manner, data were presented in a qualitative type. The result of the study showed that local communities lost their land, which used to serve for farming and residential purposes with inadequate cash compensation, rivers were contaminated by waste released from companies, labor exploitation and number of workers in several companies were disabled, and instability in the town. Investment also brought several opportunities for local people as source of income, skills and technology transfer. Local communities used daily labor, self-employment informal sector to sustain their livelihood. Based on the findings of the research, some alternatives were forwarded that could solve the problem and capitalize the opportunities available. In this regards, implementing proclamations and regulations of the country, prioritizing people in decision making and reconstructing the livelihoods of displaced household’s need emphasis by the concerned bodies.

Abstract
Wireless spoofing attacks are easy to launch and can significantly impact the performance of networks. Although the identity of a node can be verified through cryptographic authentication, conventional security approaches are not always desirable because of their overhead requirements. In this paper, we propose to use spatial information, a physical property associated with each node, hard to falsify, and not reliant on cryptography, as the basis for detecting spoofing attack;determining the number of attackers when multiple adversaries masquerading as the same node identity; and localizing multiple adversaries. We propose to use the spatial correlation of received signal strength (RSS) inherited from wireless nodes to detect the spoofing attacks. We then formulate the problem of determining the number of attackers as a multiclass detection problem. Cluster-based mechanisms are developed to determine the number of attackers. We evaluated our techniques through two testbeds using both an 802.11 (WiFi) network and an 802.15.4 (ZigBee) network in two real office buildings. Our experimental results show that our proposed methods can achieve over 90 percent Hit Rate and Precision when determining the number of attackers.

Abstract
The study examined assessment on off-campus educational life problems of female students in Robe Teachers’ College of oromia Region of Ethiopia. The specific objectives of this study were to identify the off-campus major educational life problems of female students, to examine the extent to which these problems affect female students’ academic life and to investigate the extent to which the college discharges its responsibilities. The data were analyzed using descriptive methods and linear regression. The regression model results revealed that the academic performance of female students was determined by a variety of factors. Living styles, gender sensitive pedagogy and tutorial giving methods had a significant impact on female students’ educational life, whereas silencing in the class, anxiety, perceived living home cost, dependability, personal background, distance from home to campus, peoples and students interaction can affect the educational life of female students. Therefore, policy should deal with female students’ educational life. In general, creating awareness to solve female students’ academic life and the benefit of education for all concerned bodies; creating a mechanism through which female students develop positive attitude towards academic life are essential to narrow down the educational life problems of female students. Furthermore, arranging special tutorial classes for Female students on some days of a week on regular bases for all courses to solve the problem and building dormitory and living students in with designing new rules and regulations can minimize challenges of female students under the study. On its turn, this might contribute to the UN the third MDG that says “Promote Gender Equality and Empower Women”.
