Synodontis punctifer is an endemic species in Ivory Coast. Its breeding strategies have been determined in Taabo Lake for sustainable management of stocks. In January and December 2016, 848 specimens were harvested, of which 367 downstream against 481 upstream. The s*x ratio was 1: 1.1 downstream and 1: 1.4 upstream in favor of females. The upstream landed fish consisting of all stages of development were large (13.82 ± 2 cm LF) compared to those downstream (12.31 ± 1.49 cm LF) where no mature individual was captured. There is a migration of juveniles from downstream to upstream for spawning. The first maturity size of males 16.5 cm (LF) is greater than females (16.1 cm LF). The evolution of the g***do-somatic ratio (RGS) and frequency of g***d maturation stages showed that S. punctifer breeds between August and September and is believed to be due to flooding in the lake. The absolute fecundity (Fa) of S. punctifer at Taabo lake was estimated at between 2735 to 20218 oocytes, an average of 6757 ± 4094.67 oocytes for females between 13 cm and 20.5 cm (LF) in size. These oocytes have diameters ranging from 0.6 to 1.2 mm, an average of 0.97 mm ± 0.09 at the time of egg-laying. As for relative fertility (Fr), it varied from 28,000 oocytes to 35,000 oocytes, an average of 123,000 ± 58,75 oocytes per kg of body weight. S. punctifer is a less prolific fish producing large size oocytes.
Keywords: First maturity - spawning period - fecundity - S. punctifer - Taabo hydroelectric dam (Ivory Coast).

Title: E-learning Challenges and Strategies: How to get
Implementation right: A discussion paper
Authors: Farai Choga
Abstract: E-learning is a new phenomenon for students in developing countries.
Many authors have cited benefits offered by this new learning system. Okkoyunlu and
Soyluin (2008) pointed out that it presents the course content for long periods, allows
learning process anytime and every day of the week throughout the year, reaches more
people and suitable for working adults. However there are many challenges for
institutions to get e-learning implementation process right. Such challenges as lack of
confidence in sharing ideas online, frustration and fatigue due to large amount of work
uploaded, large class sizes and lack of appropriate online pedagogy are experienced.
Many strategies can be used and among them are: catering for individual learner
needs, use of mobile phones, suitable and well-designed learning materials, staff
incentives and learning from others that have done it successfully.

Title: The Relevance of Information and Communication
Technology to Urban and Regional Planning
Authors: Akindele O. Akin and Olatoke Wole
Abstract: The paper discusses the relevance of information and communications
technology, (ICT) and the need for Urban and Regional Planning (URP) practices to
incorporate its use as a necessary change in the techniques of the profession. This is
in the light of the potential improvements that the use of ICT may bring Urban and
Regional Planning practices. The paper relied on the literature that existed on the
subject of information and usage of computer in general, to sieve out the relevance of
the same to the teaching and practice of Urban and Regional Planning. Changes in the
traditional prerequisites governing the teaching and learning of Urban and Regional
Planning was advocated and ICT which is seen as the main driving force in the
development of the information society, should be taken into account in urban and
regional planning as an important new aspect in this process. This is believed to be
helping planning into a better precision and integrity. Improved curriculum in
planning schools to necessarily embrace ICT as well as the inclusion of ICT in the
planning processes and plan preparations are some of the major recommendations of
the study

Title: Secured Palmprint Recognition Using Radon Transform for Biometric Authentication
Authors: Ms.D.Binu, Dr.P.Malathi, Ms.R.Gayathri, Mr.K.VijayAnand
Abstract: Multi biometrics provides more identification accuracy than single biometrics,
because they are more suitable for real time personal identification applications as they
need high-standard security. Though various biometrics technologies are available palm
print identification has received better attention because of its better performance.
Combination of the right and right palm print images obtains better results. Multi
biometrics is done by comprehensively combining the right and right palm images.
Matching score-level fusion is performed by three kinds of scores which is generated
from the right and right palmprint images. Initially the two kinds of scores are generated
from the right and right palmprint images and the same one can be obtained by a few
palmprint recognition methods, whereas the third kind of score was obtained using a
particular algorithm which was proposed in this manuscript. As the planned algorithm
carefully takes the nature of the right and right palmprint descriptions into account, it can
accurately exploit the similarity of the right and right palmprints of the same matter. The
proposed weighted combination method allowed better identification compared with
previous palmprint identification methods.
