TL;DR: In this paper, the authors examined the degree of the spread of the knowledge of sustainable (green) architecture in the South-South Region of Nigeria and found that only 12.5 % of the respondents have clients who are knowledgeable about sustainability in the practice of architecture.
Abstract: Contemporary Nigerian architecture seems to lack the ‘green’ in architecture due mainly to inadequate knowledge of the principles of sustainability; a serious environmental and sustainability problem. The objective of this paper therefore is to examine the degree of the spread of the knowledge of sustainable (green) architecture in the South-South Region of Nigeria. The result shall be used to judge what obtains in Nigeria and by extension, in most developing world countries, especially in Africa, south of the Sahara. This study will also create greater awareness among the practitioners of the profession. The study was done through the questionnaire/interview (technique), which sought to find how much the architects in the south-south of Nigeria knew about sustainable architecture. The analysis involved the use of means and percentages. The results of the analysis show that all the respondents agreed that the application of the principles of green architecture is very important in the practice of architecture in Nigeria, but only 12.5 % have clients who are knowledgeable about sustainability in the practice of architecture, The outcome of the analysis paved way for the conclusion and recommendations that, 1) many architects from Nigeria are yet to practice green architecture; a step they have to take if they must catch up with their counterparts from the developed nations, 2) Nigerian architects should be encouraged to train and retrain in the concepts and application of green architecture, 3) codes for sustainable building and designs should be introduced into building codes for use by all, 4) Governments and private organizations should encourage serious projects and researches on green architecture by providing funds and other necessary logistics.

TL;DR: VCO supplementary diet improved the altered KFPs and could be a therapy for kidney problems and there was no significant difference in glomerular filtration rate (GFR) and serum sodium in all the groups.
Abstract: BACKGROUND Diabetes mellitus (DM) leads to disruption of kidney function parameters (KFPs) which are markers of kidney diseases, especially nephropathy. Virgin coconut oil (VCO) has been implicated in playing a significant role in DM management. However, its role on KFPs in DM is scarce. AIM To evaluate the kidney function parameters following VCO diet in diabetic rats. MATERIALS AND METHODS Twenty-five (25) male rats of 150 - 200 g were divided into 5 groups (n=5): Non-diabetic control (Group 1), diabetes control (Group 2), diabetes + metformin (Group 3), diabetes + 10% VCO (Group 4) and diabetes + 20% VCO (Group 5). Apart from Group 1, other groups were given intraperitone-ally 50 mg/kg of streptozotocin to induce diabetes mellitus. After 72 hours, fasting hyperglycaemia was confirmed by glucose oxidase method. All the rats were fed normal rat chow for 8 weeks. At 8th week, serum and urine samples were analysed for biochemical analysis. After 8 weeks, Group 1 and Group 2 continued to be fed on normal rat chow while other groups were treated with diets (VCO) or drug (metformin) for 4 weeks. At 12th week, urine samples were collected for biochemical analysis, the rats were sacrificed, and blood samples were collected by cardiac puncture. RESULTS There were significant differences in some KFPs in diabetes control (Group 2) compared to other experimental groups. However, there was no significant difference in glomerular filtration rate (GFR) and serum sodium in all the groups. CONCLUSION VCO supplementary diet improved the altered KFPs and could be a therapy for kidney problems.

TL;DR: The extract of Vernonia amygdalina seed exhibited nephroprotective effect on the kidney of BPH induced rats, while there was no observable effect onThe liver as benign prostate hyperplasia appeared not to have had any alteration on the liver enzymes.
Abstract: Background: Benign prostatic hyperplasia (BPH) is a noncancerous enlargement of the prostate gland. The condition is associated with symptoms like frequency in urination, hesitancy, nocturia, weak urine stream and sexual dysfunction. The effect of Vernonia amygdalina extract (VA) on kidney and liver function indices in BPH was investigated. Methods: A total of 30 rats weighing 200-300 g were divided according to body weight into five groups (n=6). One group was used as a control and the other groups received subcutaneous injections of testosterone and estradiol for 3 weeks to induce BPH. Groups I and II were treated with different doses of VA extracts and group III received finasteride, all by gavages for thirty-five days. While group IV was left untreated, group V served as normal control. After thirty-five days of treatment with VA extract, the rats were anaesthetised by short contact with trichloromethane vapour. Blood was collected by cardiac puncture and the sera centrifuged and used for the determination of different biochemical indices. The prostates were harvested and weighed. Results: The level of urea and creatinine were significantly (P<0.05) reduced when compared to the Original Research Article Asuk and Ugwu; IJBCRR, 22(4): 1-9, 2018; Article no.IJBCRR.42910 2 BPH control. No significant differences in serum concentrations of AST, ALT, ALP, and GGT were recorded in all treatment groups compared to the BPH control. Conclusion: The extract of Vernonia amygdalina seed exhibited nephroprotective effect on the kidney of BPH induced rats, while there was no observable effect on the liver as benign prostate hyperplasia appeared not to have had any alteration on the liver enzymes.

TL;DR: In this article, heavy metal concentration of the Great Kwa River estuary at the southeastern coast of Nigeria was assessed using an index of geochemical analysis (Igeo). Sampling from surface sediment was conducted quarterly for a period of one year, reflecting seasoning changes in the area.
Abstract: Heavy metal concentration of the Great Kwa River estuary at the southeastern coast of Nigeria was assessed using an index of geochemical analysis (Igeo). Sampling from surface sediment was conducted quarterly for a period of one year, reflecting seasoning changes in the area. Igeo was calculated from the differences between actual current measurements and subtracted from background levels of “average shale” measurement. Based upon metals analyzed (Fe, Mn, Zn, Ni, Cu, Pb, Hg, and Cd), it was observed that there was a strong indication of potential ecological risk attributed to Cd, Zn, and Ni in the surface sediment. For effective control of pollution by metals in this fragile ecosystem, several recommendations were made including control of anthropogenic activities especially those of petroleum industry from offshore oil wells located in the area.

TL;DR: In this article, the authors investigated the comparative effectiveness of pedagogical pattern of running a course and talk-chalk methods on senior secondary school students' achievement in waves and found that female students achieved higher than male students, while there was no significant interaction effect of teaching methods and gender on students' achievements in waves.
Abstract: This study investigated the comparative effectiveness of pedagogical pattern of running a course and talk-chalk methods on senior secondary school students’ achievement in waves. It is triggered by reports of persistent students’ low achievement in physics contributed largely by students’ poor performance in waves-related items. It adopted the quasi-experimental pretest-posttest control group design. Three research questions and hypotheses guided the study. There were 216 students who participated in the study. Physics Achievement Test (PAT) containing 50 multiple-choice researcher-developed items were used as instrument for data collection. Mean and standard deviation were used to answer the research questions while ANCOVA was used to test the hypotheses at 0.05 level of significance. Results showed that: the pedagogical pattern of running a course method was superior method in fostering students’ achievement in waves; female students achieved higher than male students using pedagogical pattern of running a course strategy to teach waves; and there was no significant interaction effect of teaching methods and gender on students’ achievement in waves. From the findings, it was recommended that the pedagogical pattern of running a course strategy should be used in teaching physics in secondary school education system and in training of teachers.
