SUITABILITY OF BIOCEMENT PRODUCED BY ISOLATED MICRO-ORGANISMS AS A CEMENTING MATERIAL IN MORTAR
(Scientific Research Journal (SCIRJ), 2018) Amos N. G; Datok E.P; Dakas A.I.I; Kutshik R
This research aimed at partial replacement of
Ordinary Portland Cement (OPC) with biocement obtained from
biocementation processes induced by microorganisms for
production of mortar. Urease positive bacteria were identified,
cultured and feed into solutions containing a sterile mix of CaCl2
(0.75M) and urea (1M); 50 litres of this was produced. Mortar
prisms of 40 mm x 40 mm x 160 mm were cast using a mix ratio of
cement to sand of 1:3. A total of 54 prisms were cast and cured in
water for 7, 21 and 28 days. OPC was replaced by biocement
containing 20% pulverized fired clay at 10, 20, 30 and 50%. Bacillus
Licheniformis isolated from bovine faeces was identified as urease
positive micro-organism suitable for calcite precipitation producing
at a rate of approximately 0.67g/hour. Results revealed that
bacteria cells increased the compressive strength of mortar by 20%
and the combined effect of bacteria cells, pulverized fired clay and
biocement increased the compressive strength by 43.6% at 10%
replacement. It was generally concluded that bacillus Licheniformis
can precipitate CaCO3 through urea hydrolysis and bacteria cells as
well as biocement containing 20% pulverized fired clay at 10 and
20% partial replacement increased the compressive strength of
mortar, therefore suitable for mortar production where design
compressive strength are desired.
VEE-MAPPING STRATEGY: A GENDER RESPONSIVE TECHNIQUE FOR IMPROVING SCIENCE ACHIEVEMENT
(Interdisciplinary Journal of Gender and Women Development Studies, 2018) Bernadette Ebele Ozoji, PhD
This study investigated the effects of vee-rnapping strategy, as a gender responsive
technique, on basic science achievement of male and female students from junior
secondary schools Kaura Local Government Area of Kaduna State. Three research
questions were raised and two null hypotheses formulated to guide the study. А
randomized pre-test-post-test control group design was used. Forty male and 40
female JSS two students in two public schools constituted the sample. The schools
were selected using the simple random sampling technique. The students in intact
were also randomly assigned to experimental group and a control groups. The
instrument for data collection was a Basic Science Achievement Test (BSAT) with a
reliability coefficient of 0.78 using the test-re-test method. The research questions
were answered using mean and standard deviation while the hypotheses were tested
using ANCOVA at 0.05 level of significance. Findings of the study; revealed no
significant difference between the post-test achievement mean scores of male and
female students in Basic Science Achievement Test among others. It was
recommended that basic science teachers should employ the vee-mapping strategy as
a gender responsive- strategy for be enhancing students' thinking capacity for
improved achievement in basic science.
Characterization and Pharmaceutical Potentials of KhayaSenegalensis Seed Oil from Pankshin Plateau State
(International Journal of Research and Innovation in Applied Science (IJRIAS), 2019-05) Alexander O. Edah; Seltim B. Dalmak; Wapwera A. Jidimma
Abstract:-The fruit of Khayasenegalensis plant, family
Meliacease, were collected from Pankshin in the month of
November and appropriately identified. The seed oil was
extracted using steam distillation method, gas chromatography
and mass spectroscopy (GC-MS) was performed, antioxidant
analysis was done using DPPH according to Brand-William,
Gallic and ascorbic acids served as standard. Anti-microbial
activities was determined using Agar diffusion method with
Gentamicin 10mg/ml serving as standard. The Minimum
Inhibitory Concentration (MIC) and Minimum Bactericidal
Concentration (MBC) were determined with tween 80 as diluent.
The GC-MS indicated the presence of urs-12-ene (C30) and
dodecanoic acid (C12) etc. the extract does not show appreciable
antioxidant properties and the antibacterial analysis shows that
the activity of the oil on organism isolate increase with increasing
concentration, the oil inhibited Staphylococcus aureus,
Salmonella typhi and E.coli . The oil inhibited all the organism
isolate at the minimum concentration of 31.25mg/ml. However
the oil displayed bactericidal activities on organism isolate
throughout the concentration. The effectiveness of the oil on
organism isolate justified the claim among the traditional
communities for treatment of ailment such as typhoid, skin
rashes, boils and abscesses as plausible.
Physico-Chemical and Microbial Assessmentof Some Well Water from Mista-Ali Town, Bassa LGA, Plateau State- Nigeria
(Asian Review of Environmental and Earth Science, 2014) Kangpe, N.S; Egga, E.S; Mafuyai, G.M
The Physico-chemical and Microbial assessment of well water in Mista-Ali were carried
out to determine its suitability for domestic consumption. Samples were collected from
eight wells in duplicate and analyzed using standard methods. The results revealed the
physical parameters of the well water as colourless, odourless, tasteless, with total solids
(240-370mg/L), Total suspended solids (280-320 mg/L) and Total dissolved solids (195-
240mg/L). The chemical `parameter showed that the well has pH(6.9-7.3) conductivity
(2.0x102 -7.0x102μmhos/cm), alkalinity(12-28mg/L),Chloride (10-28 mg/L), Total
hardness (180-320mg/L), Sulphate (280-300mg/L), and Nitrate (7.70-8.20mg/L) . Arsenic
and zinc were not detected while the following metals were detected with the following
concentrations Pb (0.003-0.005), Fe (0.120-0.890),Mn (0.002-0.029), Ca (20.00-220.00),
Cu (0.002-0.006), Cu (0.002-0.006), Cr (0.001-0.008), Ni (0.004-0.011), K (2.24-9.84),
Mg (15.60-18.80). The physical, chemical and microbial assessment results were within
the permissible standard for portable water. The well water in Mista-Ali can be used for
domestic purposes and recommended that the water be analyzed atleast once every year to
check for contamination. There should also be State Agency that would license well water
to maintain high hygienic conditions.
Comparative prediction analysis of body weight from biometric traits in F1 New Zealand White purebred and its California cross bred rabbits
(Annals of Biological Sciences, 2013) O.M. Akinsola; B.I. Nwagu; M. Orunmuyi; G.T. Iyeghe-Erakpotobor; O.T.F.Abanikannda; E.D. Eze; A.J. Shoyombo; E.U.Okuda; U.Louis
One hundred and forty four (144) F1 New Zealand White purebred and New Zealand White x California crossbred
rabbits at eight weeks old were used to estimate bodyweight from body measurements using regression analyses.
Ten biometric measurements were made on each individual animal. New Zealand White x California crossbred were
superior (P<0.05) to the New Zealand White purebred for bodyweight but biometric measurements were not
statistically significant (P>0.05) between the two breed types. Phenotypic correlations were found to be positive and
significance (P<0.01) for both genotypes. The regression analysis was more sensitive in New Zealand White x
California crossbred (R2=0.85-0.91) compared to New Zealand White purebred (R2=0.84-0.89). In conclusion, body
weight could be predicted from biometric measurements for both genotypes accurately using tape measures.
