Effect of Self Regulated Learning Approach on Junior Secondary School Students’ Achievement in Basic Science

This study explored the effect of self-regulated learning approach on junior secondary school students’ achievement in basic science. Quasi-experimental design was used for the study.Two co-educational schools were drawn for the study through simple random sampling technique. One school was assigned to the treatment group while the other was assigned to the control group through a simple toss of the coin. Basic Science Achievement Test (BSAT) was the instruments used to collect data. Three research questions and three null hypotheses guided the study. The data for the research questions were answered descriptively using mean and standard deviation, while the hypotheses were tested using the analysis of Covariance (ANCOVA) at an alpha level of 0.05. The findings of the study reveal that self regulated learning strategy enhanced higher students’ achievement in basic science than the conventional method.

Social and Ecological Issues in the Works of Some Contemporary Sculptors

Ecology in social or human terms owes its stability to man's activities on the earth planet. In the mainstream of modern art, different visual artists have produced notable works that explore either social or ecological concerns, most of which revolve around issues of climate change. This paper analyses some sculptures and installations created by Quayola Alastair Noble, Jin Soo Kim, El Anatsui, Ekenechukwu Anikpe, Amarachi Okafor and Johnpaul Ezeugwu, which in different ways refer directly or indirectly to global warming. It discusses how their works provoke relevant questions or proffer solutions to problems associated with social and ecological stratification. The paper concludes that the artists have employed their art as a tool for mass orientation on the implications of undermining the natural rhythm of the earth.

The Prevalence of Malaria Parasitic Infections in Cord Blood: Association with Some Socio Demographic Profile

This study aimed at investigating the relationship between some selected socio demographic profile and malaria parasitic infections in cord blood. It involved 100 cord blood samples of newly delivered babies at the Irrua Specialist Teaching Hospital, Irrua, Edo State. Samples were subjected to microscopic examinations following standard protocols and the prevalence of malaria parasitic infections in cord blood were identified using thick and thin blood films. Plasmodium species and packed cell volume were identified and determined using rapid antigen techniques and microhaematocrit respectively. Results showed that malaria parasite was present in 9.0% of samples and was higher in babies with weights ≤1.0kg (66.70%) and PCV of 25.50% (15.40%). As regards species distribution, Plasmodium falciparum had the highest prevalence (6%). Based on the methods used, microscopic method had higher prevalence (9%) over rapid detection technique (6%). On the methods used, malaria parasitic infections was also higher among the age 36-40 years (12.5%), primigravidae (15.6%), rural dwellers (16.1%), unskilled labour (22.2%), educational status ≤SSCE (12.5%) and mothers that do not use prophylaxis (45.5%). Overall, the prevalence of malaria parasites in cord blood is low in the studied area, yet the associated consequence of mother-to-child transmission can not be ignored.Keywords: Babies, Cord blood, Demographic profile, Malaria parasites, Relationship

Peculiar Size Effects in Nanoscaled Systems

In this minireview, we intend to shed light on relatively recent examples related to the size and shape effects on materials at the nanoscale and their usage to test a set of quantum mechanics governed phenomena

<i>Ab Initio</i> Study of MgSe Self-Interstitial (Mg<i>_i </i>and Se<i>_i</i>)

We present detailed calculations of formation and thermodynamics transition state energies of Mgi and Sei interstitial defects in MgSe using generalized gradient approximation (GGA) and local density approximation (LDA) functional in the frame work of density functional theory (DFT). For both LDA and GGA the formation energies of Mgi and Sei are relatively low in all the configurations. The most stable Se interstitial was the tetrahedral (T) configuration having lower formation energy than the decagonal (D) configuration. The Mgi and Sei defect introduced transition state levels that had either donor or acceptor levels within the band gap. Sei acts as a donor or an acceptor and creates levels that were either deep or shallow depending on the configuration. Sei exhibit negative-U properties and show charge states metastability in the D configuration. Mgi acts as only shallow donor (+2/ + 1) in both T and D configurations, in addition we pointed out the role of Mgi as electrically activating donor.The National Research foundation (NRF) of South Africa (Grant specific unique reference number (UID) 78838).https://www.scientific.net/SSPhb2017Physic

A randomised controlled study of goserelin as adjunctive therapy prior to surgery in the management of uterine fibroids

Context: Luteinising hormone analogues are being increasingly advocated in the management of common oestrogendependent gynaecological conditions, notably uterine fibroids, endometriosis and menorrhagia. Objective: The aim was to assess the effects of depot injections of goserelin (Zoladex®), a GnRH-agonist analogue, on the management of uterine fibroids. Patients and Methods: Forty female pre-menopausal patients aged between 26 and 50 years, with uterine sizes 12 to 26 weeks were enrolled in a randomised controlled study. One group was prospectively randomized to surgery (deferred for 0 to 4 months) and another to goserelin treatment for 3 months, followed by surgery. Patients were included if they had a diagnosis of benign uterine fibroids and an abdomino-pelvic mass greater than 12 weeks gestational size. Results: Uterine and fibroids volumes were reduced by a median value of 31.7% and 58.1% respectively for Zoladex patients compared with an increase of 3.3% and 0.6% in uterine and fibroid volumes in the surgery-only patients. The difference between the treatment groups for the absolute changes was statistically significant (

In vitro study of the interaction between some fluoroquinolones and extracts of kola nitida seed

The cup diffusion method (CD) was used to evaluate the in vitro interaction of some fluoroquinolones (ciprofloxacin, pefloxacin and levofloxacin) with extracts of Kola nitida seed (KNS) against a clinical isolate of Escherichia coli. Minimum inhibitory concentration (MIC) of the drugs was determined separately and in combination with KNS extract in ratios of 0:5, 1:4, 2:3, 3:2, 4:1 and 5:0 against E. coli. The result of the study revealed that the MIC of the drugs decreased when combined with KNS extract. In other words, KNS extract potentiated the effects of the fluoroquinolones against E. coli

Exploring dual synergistic effects of CeO2@ZnO mediated sarcophrynium brachystachys leaf extract nanoparticles for supercapacitor electrodes applications

Cerium oxide (CeO2), Zinc oxide (ZnO) and Zinc@Cerium oxides composites (CeO2@ZnO) electrodes were synthesized using aqueous extract of Sarcophrynium Brachystachys leaf extract as comforting agent employing hydrothermal technique. The X-ray diffraction (XRD) studies revealed crystallites of various nanoparticles (NPs) sizes valued from the Debye-Scherer's equation to be 26.50, 26.77 and 26.50 nm for CeO2, ZnO and CeO2@ZnO respectively. The electrochemical analysis shown that the estimated specific capacitance acquired using cyclic voltammetry (CV) employing 10.0 mV/s scan rates are 976, 878 and 1075 F/g for CeO2, ZnO, and CeO2@ZnO respectively. Results obtained indicated clearly that specific capacitance of mixed metal oxides and Sarcophrynium Brachystachys leaf extract, an organic and natural material is better when compared with separate metal oxide alone. Sarcophrynium Brachystachys leaf extract increased the synergistic effect among constituent ions by reducing electrodes resistance, increasing electrodes conductivity and enriched electrode features
