Effect of different factors of neural network on soil profile of Khartoum state
No full textEffect of different factors of neural network on
soil profile of Khartoum stateThe Artificial Neural Networks (ANNs) is well suited to model complex problems where the relationship between the
model variables is unknown. Soil profile information can be increasingly more valuable for decision making when
coupled with Artificial Intelligence (AI). In this paper the effect of ANN geometry and some internal parameters on the
performance of ANN models was studied by apply the networks for a narrow zone .The influence of these factors
appears clearly to affect the predicting results
Comparison of two different application of neural network on Sudan soil profile
No full textComparison of two different application of neural network
on Sudan soil profileThe objective of this paper is to compare between two studies that had been carried out using ANNs in
prediction of Sudan soil profile. This importance in the design and implementation of all engineering projects which reduce
cost and time. Artificial Neural Networks (ANNs) program is applied to realize this aim. The data of 1909 boreholes from
417 sites was used firstly for a single model and then divided to five zones to be used for localized models. The input data
is the coordinate and depth and the output data is the soil classification and soil parameters. The result showed that ANNs
can be used as a good decision support and source of information for soils profiles. It is more efficient tools to be used for
small zones than all area
Evaluation of Residential Area Rehabilitation in Khartoum State
No full textEvaluation of Residential Area Rehabilitation in Khartoum StateThe aim of this paper is to describe the evaluation method used for
qualification of the site under study. The site is located in Abu Sid Block 14 at
Khartoum State. In situ and Laboratory testing were carried out to make the data
available for the evaluation. Based on geotechnical investigation, the top clay soil is
potentially expansive and problems are expected to occur due to the soil heave
associated with increase in its moisture content, if certain measures are not taken
during construction stage. Such measures and precautions have to be considered to
avoid excessive movements especially under lightly loaded buildings, floors and
underground structures. Many recommendations were derived to make optimum use
of the site as residential are

Geotechnical Investigation Report For Proposed Housing Units at Roseiris Dam Heightening Project
No full textThe Building and Road Research Institute (BRRI), University of Khartoum was
requested by Brooj Industry and Construction Services Consultancy Co. ltd to
undertake a detailed geotechnical investigation program for the proposed
Housing Units at Roseiris Dam Heightening Project. The investigation
included excavation of 96 boreholes, performing in-situ and laboratory tests to
reveal sub-soil profiles and reporting on the results with analysis and
recommendation for foundation alternatives and treatments for the proposed
structures on site

The Company of One’s Own Voice: Loneliness in Samuel Beckett’s ’Krapp’s Last Tape’
No full textThis paper had been presented for promotion at the University of Khartoum. To get the full text please contact the other at [email protected] Beckett is regarded as one of the great masters of twenties century literature, his position as a giant of his trade continues after his death and is still regarded as an incontestable figure in postmodernism.
This paper examines the notion of loneliness as an inevitable part of the human condition in Beckett’s highly successful one-act play Krapp’s Last Tape. Beckett demonstrates the ultimate solitude of the individual self.
through the genius, yet poignant idea of the protagonist listening and reacting, or not, to his own voice recordings of the past. The paper concludes that Beckett generalises his own personal experience through his plays, including the play under discussion. This conclusion is reached through an examination of his life story, his own non-fictional remarks and critical explorations on his work
Pathological, Histochemical and Immunohistochemical Studies of Lungs and Livers of Cattle and Sheep Infected with Hydatid Disease
No full textThis paper had been presented for promotion at the university of Khartoum. To get the full text please contact the other at [email protected] work was carried out to study the pathological changes in the lungs
and livers with hydatid disease of slaughtered cattle and sheep. Lungs and
livers of 521 cattle and 675 sheep were examined. Infection rates of 4.8%
and 1.8% were recorded in cattle and sheep, respectively. The predilection
sites in cattle were the lungs and the livers, while in sheep cysts were only
found in the livers. In cattle, lung and liver, cysts were mostly of medium
size (2–4 cm), but large cysts (> 4 cm) were, also, observed, while most
of sheep liver cysts were small in size (< 2 cm). The amount of fluid from
hydatid cyst of cattle ranged from 0.2 to 50 ml; only one cyst contained
600 ml. In sheep, the cyst contained small amounts of liquid with a
maximum of 3 ml. The fertility rates of the cysts were 23.4% and 11.1%
in cattle and sheep, respectively. Cyst sections from infected lungs of
cattle showed laminated membranes surrounded by a zone of cellular
infiltration of mainly lymphocytes, plasma cells, macrophages and rarely
neutrophils, eosinophils and giant cells and the outermost fibrous tissue
reaction. Calcification was, also, observed. The neighbouring tissues
showed atelectasis, emphysema, haemorrhage, congestion and fibrosis.
Sections from the second, third and fourth centimeters away from the cyst walls showed similar but less pronounced pathological reactions. In liver
cyst sections, the pathological changes were almost similar to that
observed in the lungs with atrophy and necrosis of hepatocytes.
Immunohistochemical studies revealed that all slides stained with markers
for CD³ and CD²º showed positive reaction for CD³ and negative for
CD²º. This finding suggests that the cellular reaction in the hydatid cyst
wall consists mainly of T-lymphocytes. In all liver and lung sections from
cattle and sheep stained with Masson’s trichrome stain, and fibrous tissues
in the hydatid cyst capsules or around blood vessels and air passages
stained green. The acellular laminated membranes and the protoscolices,
also, stained green. In hydatid cyst sections from cattle and sheep stained
with Periodic Acid Scheff (PAS), and laminated membranes, germinal
layers and protoscolices took positive PAS magenta colour. It is
concluded that the presence of cyst in an infected organ causes
pathological changes in tissues around the cyst and further away from the
cyst. It is, also, concluded that T-lymphocytes (CD³ positive cells) appear
to dominate the mononuclear infiltrate as demonstrated by
immunohistochemistry. This indicates that T. lymphocytes play a role in
immunological reaction against hydatid cyst
