Abstract:
Survey of spore ornamentation in
basidiomycetous ectomycorrhizal fungi revealed that 70% of the
species produced ornamented spores. Scanning electron micrograph
study showed the possible evidence for the resistance, due to
the presence of spore ornamentation, offered by ornamented
spores against getting washed off by water, leading us to
propose that ornamented basidiospores have advantage over their
smooth-spored counterparts, the former adapted for short
distance dispersal to retain the spores within the host range.

Abstract:
In this study, the mycological quality and shelf-life of
Kareish cheese
treated with different
concentrations of chitosan was investigated.
Kareish cheese was
treated with 0.5% and 1.0%
chitosan solutions prepared with 1.0 % acetic acid. The samples
were packed into plastic bags. All samples were stored at 40C
and examined every 3 days until appearance of deteriorative
changes. Kareish cheeses were evaluated
for sensorial properties and
mycological counts on days 0, 3,
6, 9, 12, 15, 18 and 21 of storage.
On The chitosan treated cheese
(o.5% and 1%) showed an improvement of shelf-life extended up to
the 18th day of storage. While in the control group
of cheese, the changes of taste and texture were observed on the
6th day while the changes in colour appear by the 9th
day. The moulds and yeasts counts ranged from 2.18 to 3.70 log
cfu /g at the end of storage period in cheese samples treated
with chitosan 1%, while in the control (non-treated) cheese was
3.40 log cfu /g of cheese at the 0 day of examination. This
count increased during storage and reached to the high level
(5.40 log cfu /g) by the end of storage period. The results
indicated that the application of chitosan on the Kareish
cheeses improves the
mycological quality and extends the shelf-life, which could an
alternative to chemical protective additives.

Understanding of Universe, Time, Odds and Environment

Abstract:
The origin of universe, the big bang, modern observations of
paradox phenomenon in Phantom Physics and surprisingly
accelerated peripheral galaxies①
have been the center of confusion in contemporary scientific
world. In this paper, a possible cause is discussed base on
classic physics. Since the energy in the universe is constant,
when the background temperature drops, the heat energy
transforms into a different form of energy -- that is momentum.
In space, the galaxies are the most significant masses that
gather in random movements when their speed drops (due to aging)②
and they cannot offset inter-mass attractions or gravities; on a
macro level, the mega aggregation of galaxies/matters provide
them ever-increasing heavier mass by collecting more aged
galaxies/mass/comic ray③along
the way. On the other hand, lost matter in the background means
lost energy, which means a drop in universe background
temperature. Gigantic numbers of regional galaxies/masses will
eventually join together and reach a critical mass level or a
critical energy level that can be labeled as a blast point,
which will trigger a gigantic explosion, similar to our nuclear
reaction. The gigantic blast is also known as a big bang that
simply bombs everything within to its most primitive state. The
blast spits out those most primitive particles, which one day
will again form atoms, then molecules -- first inorganic, then
organic④.
The universe is nothing but an unending cycle of merging and
collapsing first-forming a pre-blast mass/energy that triggers a
gigantic explosion when the mass/energy reaches a critical blast
point. The blast then spits out primitive particles that once
again form molecules and then form galaxies/planets. The mother
blast also fuels the mass with initial momentum/kinetic energy.
When the kinetic/momentum energy declines to certain levels,
those galaxies cannot resist the attractions of gravity. They
once again merge and collapse, then trigger another explosion;
then a new collection of galaxies will be formed, then they age,
then merge, collapse and blast again. The big bang/particle
explosion is triggered by a certain level (quantifiable) of
mass/energy. It cannot be an infinite level of mass/energy. It
is another logical call. To express this in a more organized
way, I will have to coin a new term for each part of the
universal system – Zolaxy, which is created by a single mother
blast. The Zolaxy is a family of galaxies created by a single
big blast. In other words, the galaxies of any Zolaxy should
have the same birth origin/mother bang. In the micro world of
sub atom level (Phantom Physics), any unrelated
particles/energies existing in experiment environment will
greatly alter the experiment results. Since a theoretical space
of temperature 0k has never been accomplished in any man-made
labs, I am afraid to say that none of those experiments is valid
in Phantom Physics. In other words, there is no evidence support
quantum mechanics or quantum laws.

Abstract:
Optimization for the preparation of activated carbon obtained
from palmyra palm nut (PPN) was studied using response surface
methodology. A three-variable Box-Behnken experimental design
was employed to correlate the preparation variables (activation
temperature, activation time and acid/precursor impregnation
ratio) to the lead uptake from aqueous solution. The preparation
variables for the production of activated carbon were optimized
based on the percentage removal of Pb2+ from aqueous
solutions. The adsorption tests were used to analyze the best
activated carbon for Pb2+ adsorption under different
conditions of temperature, time and acid/precursor ratio.
Chemical activation method which employed phosphoric acid was
used for the preparation of activated carbon. The result showed
that the optimum conditions for preparing activated carbon from
PPN for Pb2+ uptake were activation temperature of
5000C, activation time of 1hr and acid impregnation
ratio of 1.5:1 (acid/precursor, wt basis) which resulted in
95.85% removal of Pb2+ from aqueous solution. The
experimental result obtained was in agreement with the model
prediction. The adsorption studies showed that activated carbon
produced from PPN is an efficient adsorbent for Pb2+
removal from aqueous solution.

ABSTRACT:
This
paper gives an overview of the benefits, public health hazards
and risks associated with fish consumption. The comprehensive
data regarding the environmental occurrence and levels, niches,
survival, seasonality and strain diversity will be helpful for
developing sea food strategies which helps to eliminate the risk
of pathogens in exporting sea foods. Fish has become an
increasingly important source of protein and other element
necessary for the maintenance of and healthy body
Fish and seafood constitute an important food component for a
large section of world population. They come after meat and
poultry as staple animal protein foods where fish forms a cheap
source of protein. Fish and fish products constitute an
important part in the international trade, more than 50 billons
indicating increasingly consumer interest in commodity.
The quality
of our fish is of major concern to the food processors,
consumers and public health authorities and provisions of safe,
wholesome and acceptable fish and its product as food to
consumers and control of microorganisms is essential to meet
these objectives. The
quality of fish degrades, due to a complex process in which
physical, chemical and microbiological forms of deterioration
are implicated. However, some sea
foods are processed in a modern fish industry which is
technologically advanced and complicated industry in line with
any other sea foods industry and with the same risk of products
being contaminated with pathogenic microorganisms.
Although
only a few infectious agents in fish are able to infect humans,
some exceptions exist that may result in fatalities. However,
the greatest risk to human health is due to the consumption of
raw or insufficiently processed fish and fish products. Fish
acts as an important food vehicle for some zoonotic pathogens
such as Salmonella and vibrios. Contamination of fish with
pathogen is a major public health concern. The presence of
Salmonella in seafood has been reported in Vietnam, India,
Sri Lanka, Thailand, Taiwan, Japan and Nigeria. Pathogenic and
zoonotic Vibrios species have also been isolated
from stool of diarrheic patients in recent studies, and
associated with consumption of undercooked shellfish of which
these microorganisms are implicated in outbreaks of food
poisoning and diarrhea in humans. Some zoonotic vibrios have
been detected in water samples. Pathogenic Vibrios have
been a public health concern for seafood consumers and have been
cause of import bans, detentions and rejections in international
fish trade. V. parahaemolyticus and Vibrio vulnificus
among other pathogens poses a significant health threat to
humans who suffer from immune disorders, liver disease, or
hemochromatosis. Vibrio species carrying tdh
gene in fish, oyster and diarrheic stool using PCR could be
useful as basis for a preventive consumer protection policy.
Recent studies have recommended further investigation for other
virulent genes in pathogenic Vibrios.
The public should
be enlightened on the inherent danger that may accompany
handling fresh fish or consumption of improperly cooked fish.
HACCP Programs designed to prevent unsafe foods from reaching
the consumer should be employed. Seafood processors must also
keep in mind that HACCP does not replace GMPs or guard
against fraudulent practices.
Good manufacturing practices should always be observed by
trade to minimise the risk of cholera and vibrio food poisoning
associated with the consumption of seafood products. Hygienic
qualities of fish tank water in particular the source water for
keeping live seafood is also important.

Abstract:
The effects of combined
application of reduced levels of NPK fertilizer (NPK) and
poultry manure (PM) on soil and plant nutrient composition,
growth and yield of cassava was studied at two sites in Akure,
Southwest Nigeria. The treatments were the control, 600kg/ha NPK
fertilizer (recommended), 10t/ha Poultry manure (PM), 5t/ha
PM+300kg/ha NPK and 2.5t/ha PM + 450kg/ha NPK. Initial soils
were low in organic matter (OM), very low in N and P and acidic.
The PM used had relatively high N and P and good percentages of
K, Ca and Mg. Results show that relative to control, NPK, PM,
and their combinations increased soil OM, N, P, K, Ca and Mg
significantly. The 2.5t/ha PM + 450kg/ha NPK gave highest values
of the soil properties. Poultry manure alone, and in combination
increased soil pH, while NPK reduced soil pH compared to the
control treatment. There were significant increases in OM, P, K,
Ca and Mg contents of cassava as a result of application of NPK,
PM and their combinations. Nutrient content in cassava, growth
and tuber yield parameters increased in the order of Control
<NPK<PM<5t/ha PM + 300kg/ha NPK < 2.5t/ha PM + 450kg/ha NPK.
Addition of NPK fertilizer to PM increased nutrient availability
and performance of cassava. Relative to control, NPK fertilizer,
PM, 5t/ha PM + 300kg/ha NPK and 2.5t/ha PM + 450kg/ha NPK
increased tuber yield by 34, 28, 66 and 133% respectively,
application of 2.5t/ha PM + 450kg/ha NPK is recommended.

Abstract:
Acrylamide (AA) is an important industrial chemical primarily
used in the production of polyacrylamide and as a chemical
intermediate in the synthesis of a variety of other chemicals.
The discovery of acrylamide in a variety of human foods
including heet processed starchy foods such as potato chips and
bread has been reported. Acrylamide is an animal carcinogen,
neurotoxin, and reproductive toxin. AA is able to induce sperm
damage in male mice. The present study is carried out to
investigate the protective effect of vitamin E (Vit.E) against
sperm damage induced by acrylamide(viability, count , motility
and morphology).32 adult male mice were divided equally into for
groups each conaining 8 mice . mice of group 1 served as control
fed on basal diet ,group 2 received basal diet and acrylamide
(10 mg/kg, water solution) ,group 3 received basal diet and
vitamin E (100 mg/kg, intraperitoneal) and group 4 received
basal diet, acrylamide and vitamin E for 35 days. Blood was
taken for the determination of serum testosterone. Finally,
right tail of epididymis was cut in Ham’s F10. Released sperm
were used to analyze number, motility, viability (eosin-Y
stsining) and morphology (Papanicolaou stain) of the sperm. In
acrylamide mice, a significant decrease was found in sperm
viability, normal morphology and sperm motility compared to
control and acrylamid + vitamin E groups. A significant increase
was also found in sperm viability in vitamin E group compared to
both acrylamide and control groups. Vit.E not only is able to
compensate the toxic effects of acrylamid on sperm viability,
normal morphology and sperm motility, but also increases sperm
count in mice.

Assessment of the Impact of Municipal Solid Waste Landfill on

Abstract:
The contaminant impact
of a Municipal Solid Waste (MSW) landfill on groundwater at
Solous III landfill site, Lagos, Nigeria was investigated with
the aim of identifying the presence of any possible contaminants
at the site. Two (2) profiles, each employing the Neighbouring,
Opposite and Cross methods of Electrical Impedance Tomography
(EIT) were conducted at 15m locations on the site. EIT is an
imaging technique which calculates the electrical conductivity
distribution within a medium from electrical measurements made
at a series of electrodes on the medium surface and has been
principally used in medical applications. The inversion of the
data was accomplished using the Electrical Impedance and Diffuse
Optical Reconstruction Software (EIDORS) version 3.0 toolkits
for MATLAB to obtain three – dimensional conductivity profiles
called tomograms. The EIDORS package utilizes a finite element
model for forward calculations and a regularized nonlinear
solver to obtain a unique and stable inverse solution. The
scheme utilized in this work is a forward solution solved with a
mesh of 768 finite elements with 205 nodes. The reconstructed
conductivity images reveal zones of local potential contaminant
plume with conductivity > 1000 mS/m and non-conductive zones
with negative conductivity response which could be associated
with the presence of landfill gases. From the results of all the
profiles, the opposite and the cross methods have more uniform
current density distribution and therefore good sensitivity over
the entire region. In the neighbouring method, the measured
voltage is at a maximum with adjacent electrode pairs with
higher noise level. In this method also, the current is
non-uniform and there is low current density and therefore does
not yield good sensitivity over the entire region. This is
evident in the conductivity values obtained on all the profiles
of the neighbouring method which are lower than those obtained
on the profiles of the opposite and cross methods. From this
result, it shows that there has not been much impact of leachate
on the groundwater at Solous III landfill site. It is however,
observed that in the absence of a properly designed leachate
collection system, uncontrolled accumulation of leachate at the
base of the landfill poses potential contamination risk to
groundwater resource in the very near future [Ogungbe AS, Ogabi

Abstract:
Extensive application of
pesticides is usually accompanied with serious problems of
pollution and health hazards.
Lambda-cyhalothrin (LTC), a new generation type II synthetic
pyrethroid, is widely used in agriculture, home pest control and
protection of foodstuff. This study aimed to: 1. Investigate the
acute toxicity (LD50) and evaluate the effect of two
different sublethal concentrations of LTC (1/20th or
1/10th of LD50 values) on
acetylcholinesterase (AChE), Na+,K+-ATPase
and arginase enzyme activities, nitric oxide (NO•),
antioxidant status and oxidative stress biomarkers in rat brain.
2. Evaluate the possible protective role of ascorbic acid,
α-tocopherol in combination with selenium (Se)
at a dose of 100, 100 and 0.30
mg/kg b.w/day, p.o.,
respectively
as antioxidant mixture (AM)
during exposure to LTC. The
acute toxicity test revealed that LTC has low oral LD50
value (84 mg/Kg) for male
rats indicating its
moderate cytotoxic effect.
Also the results revealed that a daily exposure to LTC at a dose
of 4.2 or 8.4 mg/Kg b.w, p.o. for 4 weeks was significantly
inhibited the activities of AChE, Na+,K+-ATPase,
arginase and antioxidant defense enzymes (superoxide dismutase
SOD; catalase CAT; glutathione peroxidase GPx; glutathione
reductase GR; gluthione-S-transeferase GST) and a marked
decrease in reduced glutathione (GSH) and vitamins C and E a
long with significantly increase the brain levels of NO•,
malondialdehyde (MDA) a product of lipid peroxidation (LPO) and
protein carbonyl (PC), a product of protein oxidation as
compared to normal control rats. Daily simultaneous
administration of AM along with LTC for the same period was
significantly reduced the aforementioned changes. These results
provided strong evidence that oxidative stress is involved in
the pathogenesis of neurotoxicity of LTC in dose dependant
manner and suggested the potential synergistic and protective
effects of ascorbic acid, α-tocopherol and selenium against
neurotoxicity induced by LTC. However, further studies are
needed in different animal models with different doses to
support this novel preventive strategy to slow down the symptoms
of this LTC neurotoxicity.

Abstract:
The propensity to adopt improved rubber clones among small
holder rubber farmers in Edo and Delta states, Nigeria was
evaluated using 300 rubber farmers randomly selected and served
with a well structured interview schedule. Data collected were
analyzed using probit model to determine factors that influenced
the probability of farmers to adopt Hevea clones. Empirical
analysis of the result revealed that 76.67 percent of the
farmers adopted improved clones. The probit analysis indicated
that farm size, extension contact and income significantly
influenced the propensity to adopt improved clones among
farmers.

Abstract:
Immature, mature, and gravid specimens of Bothriocephalus
acheilognathi from Schizothorax spps. were studied by
scanning (SEM) and transmission electron microscopy (TEM). SEM
of the heart-shaped scolex revealed long, deep, pear-shaped
bothria. A bilobed apical disc was present, although it was not
prominent. The scolex tegument possessed microtriches which were
morphologically distinct from those of the strobila.
Microtriches had a more slender appearance within the bothria
than on the surrounding tegument. SEM also revealed the presence
of tumuli which were numerous and uniformly spaced on the
scolex, but became less abundant posteriorly along the strobila.
TEM revealed that tumuli contained dense-staining inclusions.
Sensory cilia extended through the tegument of mature and gravid
proglottids. The distal cytoplasmic layer was connected to the
perikarya by cytoplasmic bridges. Muscle bundles were observed
in longitudinal and cross-sections within the perinuclear
region. Various organelles, including ribosomes, endoplasmic
reticulum, and Golgi bodies, were present and within the cytons.

Abstract:
The field experiments were carried out to study the effect of
some bioregulators (glutathione, cysteine and methionine) on
growth, quality and some biochemical constituents of green onion
(Allium cepa, L. Giza 6 cv.) plants. Foliar spraying of
glutathione, L- cysteine and L-
methionine at four concentrations, 0, 25, 50, and 75mgL-1
after 33 days from sowing was used. Obtained results indicated
that the foliar spraying of the bioregulators significantly
promoted the growth and quality of green onion criteria: shoot
length, white part length, bulb diameter, number of leaves,
fresh and dry weight of onion plant. Leaf photosynthetic pigment
contents were significantly increased by L- cysteine (25mgL-1)
concentration at sprout growth stage as well as L-methionine
(25mgL-1) concentration at vegetative growth stage.
Biochemical constituents were significantly influenced by
bioregulators treatments especially in plants treated with the
different concentrations of glutathione, L-cysteine and
L-methionine. The results cleared significant increase of the
biochemical constituents; fixed oil percentage, total protein,
free amino acids, phenols, flavonoids and indoles content of
green onion at sprout and vegetative growth stages compared with
control treatment. Total sulphur content was significantly
increased by glutathione as compared with control at both growth
stages of onion plant.
