Travel behavior and determinants of mode choice of university students in Nigeria are neither well
understood nor well represented in literature. This study model `modal choice of undergraduates, using data
from students travel survey and logistic regression to determine factors influence modal choice of
undergraduate students in Obafemi Awolowo University Ile-Ife, Nigeria. The results indicate that walking
dominate modes for on-campus and commercial bus for off-campus students, while motorcycles taxi is used by
few of the sample. Mode choices are influenced by a combination of socio-economic and trip factors. A key
finding is extent that these variables positively affect the odds of using walk and commercial bus modes
especially with reference to student residence: on and off-campus. The results suggest investment in pedestrian
infrastructure and development of intermodal transport system as a means of making the university livable and
attractive.

Accessibility to health care facilities is one characteristic that have the potential
to impact the health and well-being of the elderly. Using data from a multistage
sample survey of 378 elderly, this study examines intra- urban mobility and
gender differences in hospital trips of elderly in the city of Ilesa, South-western,
Nigeria. Data were analysed using descriptive statistics, Chi-square and ANOVA.
The analysis reveals similarity in gender trip rates to hospitals - 63.14% of
elderly men and 66.29% of elderly women of the samples visited hospitals for
medical treatment during the period under study. Overall, occasional trips
frequency accounts for 96.71% of the trips to hospitals. The findings show
significant gender differences in trip frequencies, travel distance and mode
choices of the elderly. The research results reinforce the importance of intra urban
and gender variations in travel characteristics of the elderly to hospitals.

Road traffic accidents and their related deaths have become a major health problem
and concerns. Studies have examined the impact of weather on road traffic accidents and
casualties. However, the effect of weather on road traffic accidents in the existing literature is
scanty in Nigeria. In the light of the growing interest in understanding the interrelationship
between climate change and transportation including road traffic accidents, this study
examines the impact of rainfall and temperature on road traffic accidents in Ondo State,
Nigeria between 2005 to 2012. Secondary data on monthly road traffic accidents, rainfall and
temperature were derived for the study duration from the Federal Road Safety Commission
(FRSC) and Nigerian Meteorological Agency (NIMET). A total of 337 road traffic accidents
occurred between 2005 and 2012, 30.83% were fatal, 52.56% were serious and 16.60% were
minor accidents. The main finding is that the total road traffic accident is a function of
several other factors than rainfall and temperature. Specifically, correlations between road
traffic accidents and elements of weather were generally low and never exceeding 0.41. Both
rainfall and temperature were negatively and positively correlated on yearly bases. Similarly,
multiple linear regression models between road traffic accidents and the weather elements on
yearly bases show that the variations in road traffic accidents accounted for by rainfall and
temperature are equally low never exceeding 25.7%. In order to determine whether or not the
weather effects on road traffic accidents are significant, continued research using additional
weather and no weather variables is needed to replicate this study in the country.

This study was undertaken to determine the baseline pelvic parameters as assessed by computed tomographic (CT) pelvimetry in Nigerian women and to compare the pelvic parameters with those derived from other studies.The study was carried out in pregnant women at 36 weeks and above referred for routine CT-pelvimetry.
A total of 100 pregnant women at 36 weeks and above referred to the Radiology Department were prospectively recruited for this study, they included women with breech presentation after 36 weeks gestation and women who either had previous lower segment caesarean section for reasons other than confirmed or suspected cephalopelvic disproportion (CPD). The subjects' ages ranged from 24-45 years.
The mean anteroposterior and transverse inlet pelvic diameters were 11.6 cm +/-SD 0.9 and 12.0 +/-SD 0.8 cm respectively. The range of anteroposterior and transverse diameters of the inlet were 8.4 cm-14.0 cm and 10-13.8 cm respectively. The mean outlet diameter was 11.5 cm +/-SD 1.2 cm. The mean bispinous diameter of the pelvis was 10.6 cm +/-SD 0.9 cm. There was significant positive correlation between anteroposterior diameter inlet and outlet as well as the bispinous diameters (1st, 4th - 6th pairs) p<0.001.
here are significant variations in pelvic parameters of Nigerian women when compared with values from other countries of the world. These significant variations are anthropometric in origin.

Unique microstructured nickel ammonium phosphate Ni(NH4)2(PO3)4·4H2O and Ni(NH4)2(PO3)4·4H2O/GF composite were successfully synthesized through the hydrothermal method with different graphene foam (GF) mass loading of 30, 60 and 90 mg as a positive electrode for asymmetric supercapacitors. The crystal structure, vibrational mode, texture and morphology of the samples were studied with X-ray diffraction (XRD), Raman spectroscopy, Brunauer–Emmett–Teller (BET) surface area analysis and scanning electron microscopy (SEM). The prepared materials were tested in both 3-and 2-electrode measurements using 6 M KOH electrolyte. The composite material Ni(NH4)2(PO3)4·4H2O/60 mg exhibited a remarkable gravimetric capacity of 52 mA h g⁻¹, higher than the 34 mA h g⁻¹ obtained for the Ni(NH4)2(PO3)4·4H2O pristine sample, both at 0.5 A g⁻¹. For the fabrication of the asymmetric device, activated carbon from pepper seed (ppAC) was used as a negative electrode while Ni(NH4)2(PO3)4·4H2O/60 mg GF was adopted as the positive electrode. The Ni(NH4)2(PO3)4·4H2O/60 mg GF//ppAC asymmetric device delivered a specific energy of 52 Wh kg⁻¹ with an equivalent specific power of 861 W kg⁻¹ at 1.0 A g⁻¹ within a potential range of 0.0–1.5 V. Moreover, the asymmetric device displayed a capacity retention of about 76% for over 10 000 cycles at a high specific current of 10.0 A g⁻¹.

Nanoplatelets NH4(NiCo)PO4·H2O and NH4(NiCo)PO4·H2O/GF composites were synthesized through a hydrothermal approach and used as actively positive electrode for hybrid supercapacitor. Electrochemical performances of the samples were carried out in both the 3and 2-electrode measurements in 1 M KOH solution. The composite NH4(NiCo)PO4·H2O/GF exhibited an improved specific capacity of 111 mAh g⁻¹ over the pristine NH4(NiCo)PO4·H2O material with a 100 mAh g⁻¹, which was obtained at 0.5 Ag⁻¹. Moreover, an assembled hybrid device NH4(NiCo)PO4·H2O/GF//AC revealed maximum specific energy of 47 Wh kg⁻¹ and specific power of 468 W/kg at 0.5 Ag⁻¹. The device was subjected to a long-term stability test of over 10,000 GCD cycles and could retain about 70% of its initial capacity and also proved a columbic efficiency of 99.8% at 10.0 A g⁻¹. Interestingly, the device could preserve a 1.14 V of its initial potential window of 1.4 V after being subjected to a 72 h self-discharge test, showing an efficiency of 81.4%. Based on the results discussed on this work, the NH4(NiCo)PO4·H2O/GF composite could be an excellent candidate as future energy storage material, specifically supercapacitors.

Cobalt phosphate Co3(PO4)2 and Cobalt phosphate/graphene foam composites Co3(PO4)2/GF were synthesized via a co-precipitation technique. Co3(PO4)2/GF composite was synthesized from Co3(PO4)2 with addition of different graphene foam (GF) mass loading to optimize the appropriate amount of GF which effectively synergized its properties with those of the phosphate materials. The structural, morphological and chemical bonding nature of the synthesized products were characterized extensively using various microscopy and spectroscopy techniques to confirm the successful integration of conductive GF with Co3(PO4)2 grains. The electrochemical properties of the prepared materials were tested in 1 M KOH electrolyte by cyclic voltammetry (CV), galvanostatic charge-discharge (GCD), and electrochemical impedance spectroscopy (EIS). Co3(PO4)2/20 mg GF composite exhibited a remarkable gravimetric capacity of 57 mAh g⁻¹ higher than Co3(PO4)2 (21 mAh g⁻¹) at 0.5 A g⁻¹ in a half-cell configuration. An asymmetric device was fabricated using Co3(PO4)2/20 mg GF as a positive electrode) with biomass-derived activated carbon from pepper seed (ppAC) as negative electrode, which delivered a specific energy of 52 Wh kg⁻¹ with an equivalent power of 847 W kg⁻¹ at 1 A g⁻¹. The asymmetric device exhibited a capacity retention of 80% over 10 000 cycles at 10 A g⁻¹. The study demonstrates an adoption of a facile route for obtaining composite materials and interfaced with biomass-derived porous structures for assembly of a stable asymmetric device.

Dating violence is a complex phenomenon, and researchers continue to examine a wide range of precursors and contributing factors. Evidence indicates that violent intimate partners may be more likely to have personality disorders and dependency and attachment problems compared with non-violent ones. The aim of the present study is to evaluate the interaction between the personality profiles, pattern of psychopathology, and dating violence among university students in Obafemi Awolowo University, Ile-Ife. The study utilized a cross-sectional survey design with a total of 400 students selected using a multistage sampling technique. They completed the Sociodemographic Data Schedule, the Conflict Tactic Scale (CTS), Eysenck Personality Questionnaire (EPQ), and the General Health Questionnaire (GHQ). Univariate analysis was used to determine the prevalence of dating violence, psychopathology, and personality traits, and these were expressed in percentages. Association at bivariate level was assessed using chi-square and at multivariate level using logistic regression and correlations as was appropriate depending on the type of variable. The age of the respondents ranged between 18 and 35 years (M = 21.44, SD = 2.99). The prevalence of dating violence in the previous 12 months was 34%, and the prevalence of psychopathology was 15%. In the logistic regression model constructed, it was found that the significant predictors of dating violence were the psychoticism and neuroticism personality traits, which were also found to be positive correlates of psychopathology. The magnitude of dating violence found in this study is comparable with those found in other countries of the world. This study found an association between dating violence and personality in the study population and also between certain personality traits and psychopathology. The personality profiles of students could affect their interpersonal relationships greatly, and this fact must feature in dating violence prevention programs.
