Green infrastructure refers to the network of natural and semi-natural areas, features and spaces in rural and urban areas, terrestrial, freshwater, coastal and marine areas. Green infrastructure can be strengthened through strategic and coordinated initiatives that focus on monitoring, restoring, improving and connecting existing areas and features as well as creating new uses and features. The principal issue that stimulates this work is to observe how planning policies could contribute towards achievement of sustainable urban development in Malaysian urban centres using GI attributes. The procedure involved for conducting this work was qualitative content analysis of planning policies that guides physical development of Peninsular Malaysia. The analysis conducted revealed the comprehensiveness of the GI. The policies give more emphasis on protection of natural areas, followed by conservation of Malaysian environment and provision of urban green spaces. The provision of urban trail was not provided anywhere in the policies analysed. Copyright © 2017 Inderscience Enterprises Ltd.

Rainfall simulators can be a useful research tool for some purposes but are quite unsuitable for others. They have been useful in soil erosion and infiltration studies for over eight decades, but the possibility of using a rainfall simulator in urban nonpoint source pollution involving urban non-erodible surfaces has not been fully explored. In this review, the versatility of different rainfall simulators of varying sizes, configurations and styles used in the past two decades are appraised for possible adaptation to urban sealed surfaces. Recommended criteria for detailed rainfall simulator reporting are also outlined. © 2017 IAHS

Requirement elicitation is one of the most important activities in requirement engineering and allocating limited amount of time in this activity is considered to significantly contribute towards failure of software projects. Having quality requirements is also greatly influenced by the techniques utilized during requirement elicitation process. The adoption of a single requirement elicitation technique within software development projects has various drawbacks. As solution, hybrid techniques are being considered as the way towards comprehensive requirements engineering. This paper investigates the hybrid requirement elicitation technique to tackle the challenges developers are facing in the process of software development. In this paper, the combination of 3 requirement elicitation techniques, namely use of questionnaire, interview and prototyping in a unified framework is investigated during the implementation of an online educational system. © Springer International Publishing AG 2017.

The recent increase in the number of security attacks by cyber-criminals on small businesses meant that security remained a concern for such organizations. In many such cases, detecting the attackers remained a challenge. A common tool to augment existing attack detection mechanisms within networks involves the use of honeypot systems. A fundamental feature of low-interaction honeypots is to be able to lure intruders, but the effectiveness of such systems has nevertheless been affected by various constraints. To be able to secure honeypots systems, it is important to firstly determine its requirements, before taking appropriate actions to ensure that the identified requirements have been achieved. This paper critically examines how existing low-interaction honeypot systems abide to major requirements before recommending how their security could be improved. © Springer International Publishing AG 2017.

Objective: To examine the in vitro and in vivo anti-. Trypanosoma evansi (T. evansi) activity of saponins-rich fraction of Calotropis procera (cpsf) leaves as well as the effect of the fraction on the parasite-induced anemia. Methods: A 60-minutes time course experiment was conducted with various concentrations of the fraction using a 96-well microtiter plate technique, and subsequently used to treat experimentally T. evansi infected rats at 100 and 200 mg/kg body weight. Index of anemia was analyzed in all animals during the experiment. Results: The cpsf did not demonstrate an in vitro antitrypanosomal activity. Further, the cpsf treatments did not significantly (P>0.05) keep the parasites lower than the infected untreated groups. At the end of the experiment, all T. evansi infected rats developed anemia whose severity was not significantly (P>0.05) ameliorated by the cpsf treatment. Conclusions: It was concluded that saponins derived from Calotropis procera leaves could not elicit in vitro and in vivo activities against T. evansi. © 2013 Asian Pacific Tropical Biomedical Magazine.

In this paper we investigate the interaction of THz radiation with intervalence band transitions. The strong nonparabolicity and k-dependence of the transition dipole moment combined with many body effects leads to interesting features that strongly the polartonic branches as the excitation power increases. The numerical results presented can stimulate further experimental investigations for a deeper understanding of the intervalence band coupling scenario and have potential for polaritonic devices. © 2015 SPIE.

In this paper, numerical and analytical solutions for the Couette steady and unsteady fully developed laminar fluid flow in the parallel plate partially filled with a uniform porous medium and partially with a clear fluid are presented in the presence of suction/injection. The Brinkman-extended Darcy equation is utilized to model the flow in a porous region. The solutions account for the boundary effects and for the stress jump boundary condition at the interface recently suggested by Ochoa-Tapia and Whitaker (1995a, b). The dependence of the velocity on the adjustable coefficient in the stress jump boundary condition and suction/injection is nvestigated. It is shown that accounting for a jump in the shear stress at the interface and suction are essentially influence velocity profiles. It is also observed that the unsteady velocity coincides with the steady-state velocity at large times. An excellent agreement was found between the results for large time values and well-known time values for steady-state problems. © 2010 by Begell House, Inc.

This paper assesses the current management of municipal solid waste in Kano metropolis, Nigeria. Data was collected through a desk study of the operations of the state agency responsible for waste management,-Refuse management and sanitation board (REMASAB); interview with key officials of the agency; participation in the day to day activities of the agency; direct measurement and segregation of the waste; laboratory analysis of some bacterial isolate in the waste and interview with residents of the city between 2006-2013. The results of the study indicates that 79.25% of the residents do not use official dump site, 68% consider the service as very poor, 55% believe frequency of collection is unsatisfactory and 92.4% believe coverage is very poor. Presence of some bacterial isolate in the waste such as escherichia coli 86.7%, staphylococus aureus 76.7%, shigella 43.3% samonella Sp 46.7%, klebsiela Sp 43.3%, protues Sp 33.3%, indicates presence of faecal matter and may be the source of the high prevalence of cholera, diarrhea and typhoid in Kano metropolis. The high organic content 61%, ash and dirt 20%, use of unsanitary landfill portends great potential for methane generation which is dangerous to the global environment. The paper recommends a decentralised system to local authorities where local businesses can be created to utilise the large pool of unemployed as well as to explore the opportunities of the waste management chain in recycling, composting, re-use and equipments manufacture. The paper highlighted some of the constraints that must be addressed to ensure the success of the proposal, which includes, lack of data collection on waste stream, lack training and need to create awareness among the public. © (2014) Trans Tech Publications, Switzerland.

This study presents the application of some selected multivariate statistical techniques, prediction method, and confirmatory analysis to identify spatial variation and pollution sources of the Jakara-Getsi river system in Kano, Nigeria. Two-hundred and forty water samples were collected from eight different sampling sites along the river system. Fifteen physico-chemical parameters were analyzed: pH, electrical conductivity, turbidity, hardness, total dissolved solids, dissolved solids, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, mercury, lead, chromium, cadmium, iron, and nickel. Correlation analysis showed that the mean concentration of heavy metals in the river water samples were significantly positive correlated values. Principal component analysis and factor analysis (PCA/FA) investigated the origin of the water quality parameters as due to various anthropogenic activities: five principal components were obtained with 81.84% total variance. Standard, forward, and backward stepwise discriminant analysis (DA) effectively discriminate thirteen (92.5%), nine (90.1%), and six (88.5%) parameters, respectively. Multiple linear regression yielded multiple correlation coefficient R value of 0.98 and R-square value of 0.97 with significant value 0.0001 (p <0.05) showing that water qualities in Jakara-Getsi can be predicted due to high concentration of heavy metals. Structural equation modeling (SEM) confirmed the finding of multivariate and multiple linear regression analysis. This study provides a new technique of confirming exploratory data analysis using SEM in water resources management.

The existing literature on inventory of deteriorating items considers deterioration to begin as soon as the items are stocked. However, there are several deteriorating items that do not start deteriorating immediately they are held in stock. Some farm produce like potatoes, yams and even some fruits and vegetables have this property. Depletion of these items as soon as they are stocked will depend on demand, and when deterioration begins, it will depend on both demand and deterioration. In this paper, we develop a mathematical model on the inventory of deteriorating items that do not start deteriorating immediately they are stocked. The model also takes into cognizance the fact that in business activities nowadays customers are given some allowed period within which to settle for the goods supplied to them. They can use the accrued money from sales of the supplied goods to earn interest within the allowed period. They are charged interest only when they fail to settle the amount they owe the supplier at the end of the allowed period. © 2011 Elsevier B.V.
