Effects of Organic Carbon Content and Water Stable Aggregate on The Development of Rill and Gully Erosion in Aramoko-Ekiti

Field geological study of the area revealed that the erosion hazard has remained active over the years, defying control measures put in place by government, communities and individuals. Assessments of effects of organic carbon content and water stable aggregates on the development of rill and gully erosion in Iloro, Ikoyi, Alele and Atiba of Aramoko-Ekiti, Ekiti-State, Nigeria is presented in this study. 

Soil samples were collected from different depths of gully sites and their geotechnical properties analyzed using organic carbon content and triaxial tests. Results revealed that the soil in the study area has low organic carbon ranges from 1.39 to 1.43%, which results in less organic carbon, thus high erosion. The triaxial test results ranges from 6 to 150. These could be deduced that the soil is vulnerable to agents of gully erosion such as rainfall, slope of land-surface and human activities. An integrated approach including watershed management strategies, construction of ditches, retention pits at appropriate locations and a long-term re-vegetation strategy is suggested for controlling soil erosion and gulling in the study area.

Assessment of Permeability Characteristics of Ado-Ekiti to Ikere-Ekiti Road Soil, Southwestern Nigeria

There is need for good knowledge of soil permeability in order to estimate the quantity of fluid or water flow in soil, which will help in building and maintaining good road. The study sought to assess the permeability characteristics of Ado-Ekiti to Ikere-Ekiti road soil. Soil samples were taken from ten locations, subjected to permeability tests in Laboratory and the results analysed.

Results showed that that the permeability values obtained from grain size and falling head methods varied from 1.73 x 10-6 ¬to 2.15 x 10-3 mms and 8.46 x 10-2 ¬to 1.23 x 10-1 cms respectively for all the soil samples. These showed that some soil samples have high permeability, while others have low permeability. Though all the soil samples were well-graded. Thus, soil with high permeability portrayed high contents of granular materials (sand), while that of low permeability portrayed high contents of clay and its minerals. There is need for further study.

Effects of Termite Activities on Permeability Characteristics of Lateritic Soils in Ado-Ekiti, South Western, Nigeria

This research work evaluates the effects of termite activities on permeability characteristics of lateritic soils from two locations in Ado-Ekiti, South Western Nigeria. Six samples were taken from termite mound, that is, two each from top, bottom and where the queen of termite was found. Four other samples were taken from non-reworked surrounding soil. 

These samples were subjected to permeability tests using grain size distribution and falling head permeameter. The results showed that values of coefficient of permeability obtained using both parameters showed a slight agreement in trend for the two locations. Generally, the values are low but those obtained on soils reworked by termites were observed to be higher than the non-reworked surrounding soils. 

For instance, the values range from 4.90x10-5 ¬to 3.78x10-5 and 4.60x10-5 to 4.15x10-5 for non-reworked soils in locations 1 and 2 respectively, while for termite-reworked soils, slight increases were observed. It ranges from 7.29x10-5 to 6.10x10-5¬¬¬ and 6.95x10-5 to 4.53x10-5 for both locations 1 and 2 respectively. It therefore showed that there was a possible alteration of the permeability characteristics of the soil by the activities of the termite.

A Survey of Network-Based Detection and Defense Mechanisms Countering the IP Spoofing Problems

Today, the Internet is a public, cooperative, and self-sustaining facility accessible to hundreds of millions of people worldwide. The phenomenal growth of the Internet owes much to the simplicity of its design principles, which allow to widely interconnecting heterogeneous systems. The design principles of Internet' do not provide any form of control for a server to dictate how much traffic it wants to receive and from whom.

As a result, Internet hosts are vulnerable to network attacks like Denial-of-Service (DoS) and Distributed-Denial-of-Service (DDoS) attacks, whose economic and social impact has grown to considerable proportions. One of the major threats to the Internet is source IP address spoofing. In current Internet communication world, validity of the source of IP packet is an important issue. The problems of IP spoofing alarm legitimate users of the Internet. This paper review recent progress of IP spoofing detection and defenses by various researchers.

NSGA-II Implementation for Resource Allocation in MIMO-OFDMA

One of the most challenging issues for future wireless communication systems is the provision of quality-of-service (QoS) guarantees to users over the harsh wireless channels given the limited resource availability. The aim of this paper is to probe the problem of dynamic subcarrier and bit allocation in downlink of MIMO-OFDMA systems.

Using Singular Value Decomposition, MIMO fading channel of each subcarrier is transformed into an equivalent bank of parallel SISO sub-channels. NSGA-II is handled which is a multi-objective Genetic Algorithm, for joint allocation of bits and subcarriers, in the downlink of MIMO-OFDMA system. NSGA-II is intended for optimization problems involving multiple conflicting objectives. Here the two conflicting objectives are Rate Maximization and Transmit Power Minimization.

Digital Data Security by using Quantum Cryptography

Security is the most common aspect of today' world, when all things are going to digitize then make them secure over the communication channel has become the prime aim of the digital service providers. Although many encryption and decryption techniques are available in the field of the cryptography, but they all are based on mathematical calculation which are difficult to solve but not impossible. The all existing techniques can be break by using quantum computer and some extra efforts. 

But Quantum Cryptography that is free from the mathematical calculations and large prime number factorization is solution of this type of problems. Quantum Cryptography based on the laws of physics and quantum mechanics which gives the most secure way of encryption and decryption. In this paper Key Generation and Exchanging of Key is implemented by using Visual Basic software to secure the digital data over the communication channel. 

Quantum cryptography will use Photons to transmit the information over the channel which are polarized at different orientation which are 00,450,900 and 1350 from sender at some basis and these polarized information is received by second party at other end and receiver will match the received photon with his photon on his basis and matched photons will form the Key, and if anyone try to hack that information both parties will come to know about the hacking.

A Study on Properties of Modified Rotor Spun Yarn

Fibers due to their large length-diameter ratio are the most effective materials in supporting tensile loads still. Many textile applications do introduce fiber compressions either in a simple form or under complex loading conditions. The majority of these compressive loadings are directed laterally across the fiber axis like compression of fibrous assembly during draftee. Compression occurring to fabric during calendaring and embossing treatments etc. 

A special pre-compression apparatus was fabricated and mounted before the entry of fibrous strand into opening roller of rotor spinning frame. Cotton Slivers were pre-compressed in this zone at varying loads and the effect of this pre-compression on the resultant yam has been studied. The yam properties considered for the study are the studies are U%, tenacity, elongation, hairiness and imperfections. 

The drawback with rotor spun yams is lower tenacity and elongation which always need an improvement. Modified rotor spun yams obtained as a result of pre-compression of slivers shows lesser U %, reduced thin, dick and naps, lower hairiness values and mainly improved tenacity, elongation and work of rupture which would be a vital point for the industry.
