Sustainable Development of the Nile River at Greater Khartoum
Sudan is the largest country in Africa, but there is poverty and a lack of infrastructure, skills and opportunity despite its substantial natural resources. The capital of Sudan is Khartoum City,
located at the confluence of the Blue and White Nile Rivers. Unfortunately development on Nile
River Front is limited due to the risk of flooding and erosion. There is a danger that rapid
economic development may take place in this unique area without sustainable development
planning. This research project aims to develop strategies to protect the Nile River banks by
suitable stabilization methods so that development can take place safely.
Data has been collected about hydrology, morphology, geotechnical factors, soil classifications, river pattern systems, driving forces, and the main problems restricting sustainable development and engineering works for the Nile River. In addition the following have been reviewed: historical background, existing land uses, current environmental situations, and the economic and social conditions of the study areas. Research identified Cairo, Egypt as a similar case study, where data collected by the author included historical background, current situations, strategic visions and development plan for Nile River Shores. Further information was collected about sustainable development from a general literature review.
From these collected data a set of guidelines and indicators for sustainable development was
established related to environmental, economic and social factors. Based on those guidelines and
indicators, methods of stabilization of the banks for each shore were specified and a proposed
development plan was established. Methods of stabilization of banks and the development plan
were refined and evaluated to establish a final version of the development plan: Sustainable
Development of the Nile River Front (SDNRF) at Greater Khartoum. From refinement and evaluations, barriers and constraints for implementation were specified with their suggested
solutions. Finally, conclusions and recommendations related to the SDNRF Manual about
development and regulations were established

The impact of the estimation strategy of the cerebral critical closing pressure on the autoregulation index
Cerebral autoregulation (CA) encompasses a series of physiological mechanisms that are necessary to regulate blood flow in the brain. The procedure for CA assessment via the autoregulatory index (ARI) requires the estimate of the critical closing pressure (CrCP). The study aims at investigating the impact of the strategy exploited for CrCP estimation on ARI by comparing three approaches: i) fixed CrCP at 12 mmHg (CrCP12); ii) first harmonic (H1) method applied to waveforms of arterial pressure (AP) and cerebral blood velocity (CBv); iii) 2-point technique using mean and diastolic AP and CBv values (2Pm). Analysis was carried out over AP and CBv signals recorded in 25 healthy subjects (age: 44 ± 10 yrs, 12 females, 13 males) at rest in supine position and during active standing. Computation of CrCP was complemented by the assessment of the resistance-area product (RAP). We found that the H1 and 2Pm methods led to different values of CrCP and RAP. However, the strategy selected for the CrCP computation did not affect the ARI estimation, and this result held regardless of the experimental condition. We conclude that the CrCP12 strategy can be safely utilized instead of more complex methods for the CA characterization based on ARI
Genotype and phenotype report on patients with combined deficiency of factor V and factor VIII in Iran
Combined factor V (FV) and factor VIII (FVIII) deficiency is a rare autosomal recessive bleeding disorder characterized by mild-to-moderate bleeding. Epistaxis, postsurgical bleeding and menorrhagia are the most common symptoms. The aim of this study is to report the phenotype-genotype characterization carried out in patients affected with combined FV and FVIII deficiency from Iran. A cross-sectional study was conducted in Shiraz Hemophilia Center, southern Iran. Twelve cases, seven men and five women coming from eight families were included in our study after taking consent form. Coagulation activity for all patients was measured. All exons and intron-exon junctions of lectin mannose binding protein 1 (LMAN1) gene and multiple coagulation factor deficiency 2 genes were amplified by PCR, and subsequently sequenced by the Sanger method. Patients age ranged from 6 to 59 years mean +/- SD: 23.8 +/- 15.4 years and median: 22 years. No patient presented with severe bleeding symptom. Only one patient had severe FV and FVIII deficiency (both factor levels <1%). Four different type of mutations (duplication, insertion, splice site and nonsense), occurring in different locuses, were identified on LMAN1 gene in 12 Iranian patients. There was a significant correlation between FV and FVIII levels, which is indicative of association with loss of function of LMAN1 gene, and reduced plasma levels of both factors. Our study showed that all of our characterized patients with combined FV and FVIII deficiency present different homozygous mutations on LMAN1 gene introducing a premature stop codon. Larger studies are needed to calculate the correlation between factor levels, genetic and bleeding symptoms
Arab-West Report Papers 2007 - 2016
The dataset contains papers written between 2007 and 2016 by researchers and interns at the Center for Arab-West Understanding ( CAWU) in Cairo or by researchers and academics connected to CAWU. The papers aim at obtaining a better understanding of the role of religion in society, including:- Relations between Muslims and Christians in Egypt;- Problems around church building, the highly controversial topic of (alleged) kidnappings of Christian youth, claims of forced conversions, reports on sectarian incidents in Egypt and media critique to uncover biased reporting within Egypt as well as the stereotypical tone in Western media;- The role of Christian and Muslim institutions in society and the political sphere;- Activities of human rights organizations;- Islam and politics.All papers are:- Descriptive and take different points of views serious as part of the description of events unfolding in society;- Contributing to a better understanding of people between different cultures and beliefs.Methodology:Papers always include Egyptian source material. Authors were recommended to make use of the AWR database, conduct interviews in Egypt and where encouraged to contrast results with western news coverage.Papers discuss one subject at length and were reviewed by Egyptian and/or Western academics, within the bounds of organizational possibility and edited by Cornelis Hulsman or others to guarantee academic standards. This has resulted in a number of unique studies about subjects that are rarely covered in depth elsewhere. These papers are completed texts but besides, additional texts from reviewers often include interesting suggestions for further research.With thanks to:Prentice (Author), P.

A methodological approach to define the state of conservation of the stone materials used in the Cairo historical heritage (Egypt)
The use of stone materials in cultural heritage and architecture represents a practice that has its roots in ancient times. Stone buildings, depending on the construction materials and their location in the urban context, are particularly vulnerable to weathering phenomena. These can be often accelerated by changes in environmental conditions linked mostly to the anthropic activities. In this way, the present work is addressed on the minero-petrographic and geochemical characterisation of samples taken from the built historical heritage in Cairo (Egypt), related to seven monumental areas. These sites have been chosen based on their historical importance, type of material, state of preservation and position in the Cairo context. The construction materials used and their degradation products were studied comparing the results obtained by means of different analytical techniques such as polarised light optical microscopy (POM), ion chromatography (IC), Fourier transform infrared spectroscopy (FT-IR) and the carbonaceous fraction, detected by using the thermogravimetry (TG). The results achieved demonstrated that black crusts and salt crystallisation represent the most common and damaging degradation products affecting all the monumental sites. Moreover, the environmental pollution produced by industrial activities and vehicular traffic has been identified as the main cause of these processes, followed by a marginal contribution of natural sources such as the sea spray. The data collected provide useful information to plan efficient conservation strategies in the future
Status of the Cabibbo-Kobayashi-Maskawa matrix and unitarity triangle fits
The status of the Unitarity Triangle analysis realized by the UTfit Collaboration is presented. The most recent determinations of theoretical and experimental parameters are used in order to over-constrain the apex of the Unitarity Triangle in the Standard Model. In addition, we present the analysis of the Unitarity Triangle beyond the Standard Model, by parametrizing New Physics contributions in Delta F = 2 processes. With the new measurements from the Tevatron, namely the mass difference Delta m(s), the width difference Delta Gamma(s) and the di-muon asymmetry, it is possible to establish significant bounds on New Physics parameters also in the B-s sector. The results and the plots presented in this paper can be found at the URL http://www.utfit.org, where they are continuously kept up-to-date
Ippolito Rosellini, l'Egitto, l'Egittologia /Ippolito Rosellini, Egypt and Egyptology
The paper focuses on Ippolito Rosellini, co-director with J.F. Champollion of the Franco-Tuscan Expedition to Egypt (1828-29) and first Professor of Egyptology in Europe, at the University of Pisa. His important contribution to the formative phase of the new-born Egyptology is highlighted through the study of his unpublished manuscripts and some drawings of the Expedition in the Biblioteca Universitaria of Pisa. These documents were studied, digitized and put on the web in the framework of a specific project, directed by the author, “Progetto Rosellini”. The volume including this paper, it too edited by M. Betrò, is the catalogue of the homonymous exhibition organized by the author in the Egyptian Museum of Cairo in 2010. The international exhibition exposed for the first time in Egypt about one hundred drawings and manuscripts among the most important and beautiful from Ippolito Rosellini and the Tuscan Expedition Archive
