Diversity and Foraging Guilds: Focus on Hadejia-Nguru Wetlands Avifaunal Community

Abstract: 

Wetlands being a complex ecosystem are well-known for their rich bird species by serving as shelter and foraging ground. However, information on the avian species foraging guild of the Hadejia-Nguru Wetland is unknown and diversity is relatively understood. Using point count method, a total of 14 wetland sites were surveyed from October to December, 2015. A total of 99 census points spaced 400 m apart with 100 m radius were used to surveyed birdsfrom 14 wetland sites. A total of 148 bird species belonging to 23 orders and 50 families were recorded. Among these, 94 (64.19%) were resident, 20 (13.51%) intra-African migrants, and 34 (22.30%) Palearctic winters. Results showed that Muzza wetland was the most diverse (H'= 3.13), followed by Barrack (2.94) and Hadejia Barrage (2.83), whereas Kandamau was the least diverse (1.04), followed by Kwasabat (1.11) and Dumbari (1.33). On the other hand, avian assemblages in Hadejia-Nguru Wetlands were composed of more insectivorous 49.32%, granivorous 14.86%, frugivorous 13.53%, carnivorous 13.51%, piscivorous 7.43%, and fewer vegetarians 1.35%. The diverse array of bird species recorded in this study highlights the conservation importance of Hadejia-Nguru Wetlands. Nevertheless, more studies are needed to understand the relationship between birds and habitat structure, competition and predation among the local bird assemblage to guide future conservation. It is recommended that the wetland management increase public awareness on the importance of birds conservation in the wetland.

The Rijndeal Cipher (A Review

Abstract: 

Since its adoption by the National Institute of Standards and technology, the Rijdeal cipher has become a standard in public and private key encryption in the internet. Recent researches have however exposed marginal but still important flaws in the rijdeal algorithm. This research reviews the Rijndeal cipher and some of the more significant attacks that have successfully broken the cipher. But despite these signiicant lapses, after comparison with other algorithims such as the DES and triple DES (3DES), the Rijdeal cipher was found to have superseded them in terms of security ans efficiency. As part of the research, the Rijndeal cipher was fully implemented using Matlab and the code shared publicly on GITHUB

Overview and Challenges in Modern Wireless LAN Security

Abstract: 

Wireless networks especially the Wireless Local Area Networks (WLAN) is a means of providing an inexpensive and easy way in sharing common digital resources such as a single Internet connection among several computers. Using a wireless network to transfer files makes digital life faster and eliminates wired connections. Hence, WLAN are playing a major role in the information technology revolution. The increasing need for WLAN technology has led to a closer examination of its security vulnerability, hence, the need for an accurate assessment of the reality of the current state of the security of wireless 802.11-based environments. By reviewing WLAN technology literatures, this paper aims to overview the WLAN structure, its challenges and point out its shortcomings.

Design and Development of an Android-Based Mobile Hospital Recommendation Application

Abstract: 

Human beings are living less while also giving birth to more children, and this is exerting more pressure on the environment and resources. There is an increasing need for easier ways of getting access to health-care services. Despite the number of mobile health applications that exist for self-care, there is a scarcity of research into individual interaction with electronic healthcare systems. This paper presents the design and evaluation of a health recommendation application using iterative enhancement model that assists individuals in finding qualitative health institutions, the services they offer, and their GPS locations. The paper also points out some suggestions for future possibilities that can improve healthcare delivery and the wellbeing of individuals. The software is tested across three (3) of the latest Android Operating System and found to be efficient and user friendly.

SPATIAL ANALYSIS OF BEST SITES FOR SECONDARY WASTEWATER TREATMENT PLANTS IN KANO METROPOLIS, NIGERIA

Abstract: 

One of the basic needs of every life have been conducive environment, and one of the determinants of conducive environment for successful life have been proper wastewater management, the study area is one of the highly urbanized and industrial community in Nigeria but its lacks secondary wastewater treatment plant. The aim of the study is to spatially identify and map out best sites for the construction of secondary wastewater treatment plants in Kano metropolis. The process involved the preparing of suitability maps based on constraint criteria of factors such as densely populated areas, surface rivers, major roads, rail line, airport, ground slope and land use – land cover of the area using Geographical Information System (GIS) and weighted using pair wise comparison Matrix (AHP) and finally the weighted maps are integrated using weighted overly tool in Arcgis 10.1. Based on the weighted values suitable sites for the treatment plant have been identified and classified into unsuitable, suitable and most suitable while ten best sites have been map out from the most suitable areas.
