Occupational mobility in engineering profession (craftman and artisan) in Oyo State, Nigeria.
This paper evaluate occupational mobility in engineering professional in Oyo State of Nigeria with the goal
assessing causes and readiness of the professionals to return to the profession when the hindering factors
are removed as well as sufficiency of the survey instrument in addressing the research problems. The
study was conducted using a well structured questionnaire administered in 20 local government of Oyo
State, Nigeria representing the sample space of 0.424. The Cronbach’s alpha of the reliability test of 0.453
was returned for the scale mean statistics of 11516.83 and variance of 0.0000007 showing that the survey
instrument was sufficient and could be relied upon. The result of the socio economic analysis showed that
80% of the respondents were married while (15%) were single and the rest (5%) were divorced. The age
distribution of the respondents ranged between greater than 50 years groups (12%) and 30 -39 years
group (39%).The result of the analysis of job characteristics of the respondents showed that the longer the
year of graduation, the lesser the number of graduates still in the business. The cross table analysis of the
socio-economic indices with the job status of the respondents showed that marital status and level of
education does not have significant effects on the job status of the respondents (whether still practicing or
not) because 1.454 and 5.223 returned for both marital status and level of education are not significant
(P<0.05). Also, the contingency table analysis of the effects of the skill acquisition methods showed that
more of the respondents who acquired their skill via Technical School (70%) are willing to go back to the
professions. However, for those who acquired their skill through Learning/artisanship, less than average
(32%) of the respondents are ready to return to the profession. Lastly, the establishment of the regression
model for the relationship between the proportion of the people wishing to go back to the profession and
year of practicing the profession provide a necessary impetus for addressing the Job mobility problem
faced by the profession
Gravitation interaction with extra dimension and periodic structure of the hadron scattering amplitude
The behavior of the hadron scattering amplitude determined by the gravitation
interaction of hadron at high energies with impact of the KK-modes in d-brane
models of gravity is examined. The possible periodic structure of the
scattering amplitude and its dependence on the number of additional dimensions
are analyzed. The effects of the gravitational hadron form factors obtained
from the hadron eneralized parton distributions (GPDs) on the behavior of the
interaction potential and the scattering amplitude are analyzed. It is shown
that in most part the periodic structure comes from the approximation of our
calculations.Comment: 9 pages, 8 figures, talk on the Intern. Workshop "Bogoliubov

Band twisting and resilience to disorder in long-range topological superconductors
Planar topological superconductors with power-law-decaying pairing display
different kinds of topological phase transitions where quasiparticles dubbed
nonlocal-massive Dirac fermions emerge. These exotic particles form through
long-range interactions between distant Majorana modes at the boundary of the
system. We show how these propagating-massive Dirac fermions neither mix with
bulk states nor Anderson-localize up to large amounts of static disorder
despite being finite energy. Analyzing the density of states (DOS) and the band
spectrum of the long-range topological superconductor, we identify the
formation of an edge gap and a surprising double peak structure in the DOS
which can be linked to a twisting of energy bands with nontrivial topology. Our
findings are amenable to experimental verification in the near future using
atom arrays on conventional superconductors, planar Josephson junctions on
two-dimensional electron gases, and Floquet driving of topological
superconductors.Comment: 9 pages, 8 figure
IN-SILICO APPROACH TO THE DEVELOPMENT OF A PROTOTYPE CLINICAL INFORMATION SYSTEM FOR PEDIATRIC UNITS
There is an observed serious challenge to the provision and management of pediatric healthcare and facilities in most African countries. This has probably contributed to the high mortality rates recorded among African children. It is thus imperative to evaluate all possible approaches to the development of the appropriate manage of the problem. In-silico approaches to information management of pediatrics sections of hospitals could for example help reduce mortality rates among children. This study was aimed at developing a prototype clinic information system for keeping track of infants’ clinical records, diagnosis of their various ailments, proffering possible solutions and their respective responses to drug treatments. Research focus was on the pediatric sections of some hospitals located in southwestern part of Nigeria, particularly sections in care of the children between the ages of 5 and 9 years. A monthly or annual report generated from this system will assist in making proper recommendation to research institutions on ways of improving chemotherapeutic management of common diseases of infants and to governmental agencies on the need for more funding to support in this quest. C#.Net was the programming language used for the implementation of the system, while SQL server 2008 was used to provide the database support. It is hoped that the developed system will help in the reduction of infant mortality rates in hospitals were it is implemented
Rauvolfia vormitoria Effect on the Degradation of Aluminium Alloy in 2.5 M Hydrochloric Acid Solution
The deterioration of aluminium alloy in 2.5 M hydrochloric acid in the presence Rauvolfia vormitoria
extract was examined using both gasometric and gravimetric techniques. Aluminium coupons measuring
4 cm by 1 cm were introduced into test solutions of uninhibited acid and also those containing extract
quantities of 10, 20, 30 and 40 cm3 at ambient temperature of 250C for a total cumulative period of 117
minutes. The volumes of hydrogen gas evolved and weight loss readings were recorded and analyzed to
obtain weight loss and corrosion rate for each coupon at specific time intervals. The results however,
showed that while extract quantity was increasing; weight loss measurements increased but inhibitor
efficiency decreased. Also, the metal surface-phytoconstituent interaction mechanism was consistent with
the Temkin adsorption isotherm and the 3 minutes curve showed the best exposure time for
phytochemicals to adsorb to alloy surface. Furthermore, microstructural studies showed an indirect
relationship between metallic degradation and extract quantity, while uniformity of the irregular
intermetallic phases increased with increasing extract quantity
