The compatibility of an airport with its environs can be achieved by proper environmental control and planning of the airport, control of pollution-generating sources, and land use planning of the area surrounding the airport are paramount if disasters are to be averted or reduced to the acceptable standard. This study was carried out to assess the compliance to standards of the activities relating to environmental control and planning at Kaduna International Airport as contained in International Civil Aviation Organization (ICAO) and other Airport regulations Guidelines. The objectives including assessing the environmental impact associated with aviation activities, assessing environmental consequence and control measures and assessing land use planning at the Airport. The Airport Environmental Management Handbook, Federal Airport Authority of Nigeria (FAAN) Hand book, ICAO Documents, Maps and other relevant information were consulted. Questionnaires were distributed and percentage distribution was used in analyzing the objectives. Results from this study has shown an acceptable level of compliance in Environmental Planning by the relevant authority of Kaduna International Airport. The results from this study will be useful to FAAN, ICAO and other relevant Agencies in enhancing Environmental Control and Planning at Airports for Disaster Risk Reduction.

In Nigeria the beginning of automation of meteorological parameters was dated back to 1998 when five Automatic Weather Observation Systems (AWOSs) were installed at different locations. Unfortunately we were unable to sustain those equipment due to low literacy level of most operational staff available at the time of implementation. The Nigerian Meteorological Agency (NIMET) is making frantic efforts to ensure provision of timely and accurate Weather Information through acquisition of weather monitoring systems and training of technical and operational personnel on

In Aviation, the field of communication encompasses a broad range of activities which includes the operation of navigational aids on the ground, in the air and in space and the development of associated technical requirements, specification and procedures. Communication equipment consists of radars and landing aids as well as air-ground and ground to ground telecommunication equipment. Radio communications on very high frequency (VHF) and high frequency (HF) plays complementary role and are the backbones of air traffic control operations. Telecommunication in aviation can be broadly categorized into either aeronautical fixed services (AFS) or aeronautical mobile service (AMS). The paper illustrates AMS and how bulk voice communication between ground and air was achieved using Radio (Tx/Rx) over Satellite links for aeronautical safety communication in the upper airspace.

Cryptography is fundamental to the provision of a wider notion of information security. Electronic information can easily be transmitted and stored in relatively insecure environments. This research was present to factor the prime power modulus \(N = p^r q\) for \(r \geq 2\) using the RSA key equation, if \(\frac{y}{x}\) is a convergents of the continued fractions expansions of \(\frac{e}{N - \left(2^{\frac{2r+1}{r+1}} N^{\frac{r}{r+1}} - 2^{\frac{r-1}{r+1}} N^{\frac{r-1}{r+1}}\right)}\). We furthered our analysis on \(n\) prime power moduli \(N_i = p_i^r q_i\) by transforming the generalized key equations into Simultaneous Diophantine approximations and using the LLL algorithm on \(n\) prime power public keys \((N_i,e_i)\) we were able to factorize the \(n\) prime power moduli \(N_i = p_i^r q_i\), for \(i = 1,....,n\) simultaneously in polynomial time.
