Tongue rolling and hand clasping among various ABO blood groups in a University community in Eastern Nigeria
Morphogenetic traits are physical observable traits that can be inherited either in a single gene or multifactorial pattern. ABO blood group is a codominant inherited trait that has been associated with different anatomical and physiological variations. However, there are limited studies that have linked ABO blood groups with some morphogenetic traits.
This study was conducted to ascertain the distribution of morphogenetic traits like hand clasping and tongue rolling among ABO blood groups in a University community in Eastern Nigeria.
A total of 115 volunteers participated in the study. The blood groups of the participants were determined and the expression of the morphogenetic traits was gotten by physical observation. Greater proportion of the participants were males (55.65 %), students (61.74 %) and within ages 15−25 (58.26 %). There was a higher prevalence of blood group O (57.39 %), tongue non-rollers (53.04 %) and right hand clasping (74.78 %) among the participants. The participants with blood groups A and O recorded a higher distribution of tongue non-rollers while those with blood groups B and AB recorded an equal number of both tongue roller and non-rollers. The participants with blood groups A, B and O recorded a higher distribution of right hand clasping while those with blood group AB recorded a significant higher distribution of left hand clasping (P<0.05).
In conclusion, morphogenetic pattern of tongue rolling could not be associated with ABO blood group, whereas that of left hand clasping was associated with blood group AB suggesting that individuals with blood group AB is likely to exhibit left hand clasping; forming basis for determination of hand clasping using ABO blood group in future advancement of genetics and forensic scienc
The telecom value chain, opportunities and revenues created by the nigerian telecom boom
In Nigeria today, we face a serious economic challenge which is as a result of our swindling primary source of revenue (oil), there is fear amongst our economists which is can Nigeria bounce back to what she once was? Can there be an alternative source to serve as a buffer to what we already have. This study aims to bring to prime focus, an industry which has begun blooming in the background. Despite the publicity and popularity enjoyed by today’s telecom giants in the country, there is very little knowledge pertaining to the tremendous impact that it has had directly or indirectly on our economy over the years. Since the liberalization of the telecom industry that brought about the involvement of private investors into the sector, the opportunities and revenues generated has brought about a tremendous effect on the economy. The telecom sector is only second after the oil and gas industry in the amount of finance it contributes to the federal account. This paper discusses some of the value chains, opportunities, revenue that the telecom industry has brought to Nigeria. It uses data obtained from relevant authorities
MIMO channels: optimizing throughput and reducing outage by increasing multiplexing gain
The two main aims of deploying multiple input multiple out (MIMO) are to achieve spatial diversity (improves channel reliability) and spatial multiplexing (increase data throughput). Achieving both in a given system is impossible for now, and a trade-off has to be reached as they may be conflicting objectives. The basic concept of multiplexing: divide (multiplex) transmit a data stream several branches and transmit via several (independent) channels. In this paper, we focused mainly on achieving spatial multiplexing by modeling the channel using the diagonal Bell Labs space time scheme (D-BLAST) and the vertical Bell Labs space time architecture (V-BLAST) Matlab simulations results were a lso given to further compare the advantages of spatial multiplexing
