Abstract:
Matured trees of Pycnanthus
angolensis (20.0±5.0years) were purposively selected from
Oyo (Idito ID, Adewumi AD), Osun (Gbongan GB, Ajaba AJ), and
Ekiti (Otun OT, Ayetoro AY) States, based on availability. Onset
and duration of flowering and fruiting (months) and period of
fruit colour change (days) were
monitored for 24 months. Flower initiation ranged from
September-November in which GB initiated flower in October, AJ
(September), OT (November), AY (November), ID (November) and AD
(November). However, OT, AY, ID and AD initiated flower at the
same time. Flower formation also occurred between
October-January. In GB, it occurred between Nov – December for
(30days), AJ October 3rd–November. 30th for (58days),
OT November 8th– December 8th
(30days), AY November 8th–December 8th
(30days), ID and AD formed flower between December
8th–January8th (30days). Flowering period/ duration

An Alternative To Chemical Dosing In Raw Water Treatment

Abstract:
To examine the effectiveness of electrocoagulation treatment of
water as a substitute for chemical coagulation in the treatment
of fresh water, samples of raw water were collected from Opa dam
of Obafemi Awolowo University, Ile-Ife and analyzed. The pH,
turbidity, dissolved oxygen, average total solids and total
dissolved solids of the samples were determined using standard
methods.
A batch process electrocoagulation reactor was constructed and
used to determine the effects of varying the electrode spacing
and current, with the turbidity removal, heavy metal
concentration reduction and the current efficiency being a
measure of the effectiveness of the electrocoagulation process
in treating the water. The effect of varying time and surface
area to volume (A: V) ratio on the current efficiency and
turbidity removal efficiency was investigated. A jar test was
conducted to compare the requirements (in terms of aluminium/alum
dosage) and effectiveness of treatment by electrocoagulation
with treatment by chemical coagulation. The TSS, pH and
turbidity removal efficiency were used in this comparison. A
continuous process electrocoagulation reactor was then designed
by adding a pre-treatment storage and sedimentation units. The
turbidity removal efficiency and the dosage was determined and
compared with that obtained from chemical coagulation. The
results obtained show that electrocoagulation is a viable
alternative to chemical coagulation in the treatment of water at
Opa dam. The treatment was most effective at a current of 2.5 A
and an electrode spacing of 2.0 cm, and an electrocoagulation-flocculation
period of 5 minutes followed by 30 minutes of sedimentation. The
turbidity removal efficiency averaged 90%, as compared to the
75% obtained from chemical coagulation. Also, electrocoagulation
resulted in a decrease in BOD without change in pH, while
chemical coagulation resulted in a discernable increase in the
acidity of the water samples.

Abstract:
The ecological condition of river is represented by the condition of
their biotic communities — the living components of aquatic
ecosystems that integrate many forms of human disturbances and
modification of river stream and the measurements of this
subject was the topic of particular interest. Stressors or the
pressures that human being exert on aquatic systems through
their use of the surrounding environment are commonly the
chemical, physical and biological components of the ecosystem.
These have the potential to degrade biotic integrity. Some
common chemical stressors are toxic compounds, excess nutrients
etc. Most of the physical stressors are created when we modify
the physical habitat of a river network-excess sedimentation,
bank erosion etc. All these can degrade biotic integrity. Water
quality plays vital role in riverine ecosystem health
regulation.
Environmental indicators have
been defined as “physical, chemical, biological or
socio-economic measures that best represent the key elements of
a complex ecosystem or environmental issue. An indicator is
embedded in a well developed interpretative framework and has
meaning beyond the measure it represents.
Using indicators, it is
possible to evaluate the fundamental condition of the
environment without having to capture the full complexity of the
system. Indicators are based on the best scientific
understanding currently available so that changes in these
simple measures can be related to more complex environmental
trends.

Reconstruction Of The Population In The Fergana Valley Regions
And Its Territorial Characteristics
Temirov Zokirjon Abdilvoxidovich
Basic doctoral student，
Andijan State University, Uzbekistan
Annotation:
During the years of independence in Uzbekistan, special
attention has been paid to the regional aspects of demographic
issues based on the human factor, the principle of a healthy
mother and a healthy child. The course of demographic processes
changes in accordance with the natural, socio-economic and
geographical conditions of the regions. The Fergana Valley is
the most densely populated region of Uzbekistan, with a small
area, heavy demographic load and the largest demographic
potential. This article examines the reproduction of the
population of the Fergana region, the general, special, specific
and cumulative birth rates, survival, gross and net
coefficients, and draws conclusions.

Abstract:
There is an increasing need to
improve the engineering properties of soils using locally
available and economical materials. This work therefore studied
the effect of banana leaf ash (BLA) on the geotechnical
properties of selected lateritic soils. To achieve the aim of
this study, lateritic soil samples were collected from
identified locations in Ile-Ife, Osun State, Nigeria. In their
natural states, the soil samples were subjected to the following
laboratory tests, using standard procedures: natural moisture
content, specific gravity, grain size analysis, Atterberg
limits, compaction and California bearing ratio (CBR). The BLA
was added to the soil samples in 2 %, 4 % and 6 % proportions by
weight of soil; and the geotechnical properties were also
determined for the soils with BLA. Results showed that addition
of BLA improved the properties of the soils, that is, with the
addition of BLA, reduction was generally noticed in the values
of plasticity index for both soils. The optimum values of CBR
were 39 % (sample A) and 30 % (sample B), which were obtained at
4 % BLA for the two samples. The study concluded that BLA can
cause significant improvement in the strength of lateritic
soils.

Abstract:
Searching of documents/text is
the most important need of each student or user computer.
Searching through particular index or term is the old fashion,
now a day’s user want to search documents according to some
phrase, query or requirement i.e. extraction of meaningful
information from large collection according to some textual
query. Different methods such as Iterative Residual Rescaling (IRR),
Term Frequency (TF), Inverse Document Frequency (IDF), multi
words is using to handle such issues. Latent Semantic Indexing
(LSI) is an important method for current literature of
information retrieval. LSI can find similar documents on
particular textual phrase. Here authors has implemented two
algorithms (without and with Pre-Processing) of LSI for text
documents. As a result, both algorithms can obtain the similar
results but their processing time will be different.

Abstract:
Banana fibers (BFs) are utilized as reinforcement to compensate
for concrete's inherent weaknesses. Nowadays, there is a focus
on incorporating BFs into concrete, depending on them to develop
alternative building materials. Numerous advantages associated
with the usage of BFs reinforced concrete include higher bending
strength, enhanced post-crack load-bearing capability, and
others. This context provides an overview of the physical,
chemical, and biological pretreatments applied to BFs, their
consequences, and the resulting fibrous concrete. This section
concludes with conclusions, and recommendations for more
in-depth research on the issue.
