Christians and Muslims Faced with the Wrath of Abū Marwān al-Yuḥānisī, a Thirteenth-Century “Friend of God”

This article examines the nature of the wrath of Abū Marwān al-Yu[hdot]ānisī, a thirteenth-century Andalusi saint, and the protagonist of the Tu?fat al-mughtarib of al-Qashtālī. I have divided the study into two main parts. The first sets out and analyses various occasions on which the saint committed violent acts against Christians. Two of them died as a consequence of these aggressions. All the cases in this first part took place in the Muslim East during the saint's stay in this area. The second part examines cases of violence committed against Muslim people from al-Andalus. The victims suffered the consequences of the wrath of the saint, although he was not directly involved in the aggressions themselves. The stories are narrated by al-Yu[hdot]ānisī himself, and we do not know whether they really took place. Regarding these manifestations of violence, the hagiographic sources not only justify all the violent acts committed by the saint, murder included, but they present the saint to society as an “example” to follow, and indeed as a “hero”.     

Application of polyurethane geocomposites to help maintain track geometry for high-speed ballasted railway tracks

There are many issues surrounding the performance of critical assets on high-speed ballasted railway lines. At assets like switch & crossings and bridge transitions high track forces can be produced resulting in higher ballast settlements and hence track misalignments. The latter result in higher track forces and hence more settlement, leading to the need for increased track maintenance to ensure comfort and safety. Current technologies for solving issues like ballast movement under high-speed loading regimes are limited. However, a technique that has been well used across the UK and now increasingly overseas to stabilise and reinforce ballasted railway tracks is the application of in-situ polyurethane polymers, termed XiTRACK. This paper discusses how this technique can be used to solve these types of long-standing issues and presents actual polymer application profiles at two typical critical sites, namely a junction and a transition onto concrete slab-track.     

Correlation and Multiple Regression Analyses of Pituitary Growth Hormone and Hepatic Activities in Hepatitis C Infection and Interferon Response

The prevalence of hepatitis C virus (HCV) infection varies across the world, with the highest percent of infections reported in Middle East, increasingly in Egypt. The current study aimed at examining the bio-statistical correlation and multiple regression analyses of pituitary growth hormone (GH) and liver activities among HCV genotype-4 patients treated with PEG-IFN-α plus RBV therapy. Herein, the current study was conducted on 100 HCV genotype-4 infected patients and 50 healthy controls. Patients received PEG-IFN-α/RBV for 24 weeks. Host RNA was isolated from patients’ sera for HCV genotyping and viral load determination. Moreover, the enzymatic activities of the liver, AFP, GH, PT, and CBC were performed in all volunteers. The present study resulted that the activities of the hepatic enzymes among HCV genotype-4 patients correlated together significantly. While, human GH showed a significant positive regression with pre-treatment ALT concentration in responders. Furthermore, multiple regression analysis for GH showed a significant positive correlation with pre-treatment ALT in HCV genotype-4 infected patients. We concluded that there were a putative significant relation between GH and pre-treatment ALT activity in HCV infection and response to IFN-based therapy.

Transport and deposition of airborne pollutants in exhibition areas located in historical buildings–study in Wawel Castle Museum in Cracow,Poland

Historical buildings and castles that have been turned nowadays into museums, as an exhibition area for precious cultural heritage (CH) items, need more attention since they are CH objects by themselves. Moreover, the preservation techniques require often, significant interventions; however such changes are not always possible or are very limited. The aim of the present study was to investigate the influence of outdoor air pollution on the composition of particulate matter and gases inside the museum of Wawel Castle in Cracow, Poland. During this study a combination of micro and trace analysis techniques were applied, including energy dispersive X-ray fluorescence (EDXRF) and electron probe microanalysis (EPMA). An intensive transport of air pollutants coupled with accumulation of the particles inside the museum was noticed (considerably higher in winter than summer). A high content of carbon and organic matter agglomerated with inorganic particles was determined. Those particles are of special concern because of their adhesive properties and reactivity. It was also noted that the conditions inside the museum favour the reaction of the particles with gaseous pollutants. It was especially the case for nitrate particles.     

From scientific practice to high school science classrooms: Transfer of scientific technologies and realizations of authentic inquiry

The Biology Workbench (BW) is a web‐based tool enabling scientists to search a wide array of protein and nucleic acid sequence databases with integrated access to a variety of analysis and modeling tools. The present study examined the development of this scientific tool and its consequent adoption into the context of high school science teaching in the form of the Biology Student Workbench (BSW). Participants included scientists, programmers, science educators, and science teachers who played key roles along the pathway of the design and development of BW, and/or the adaptation and implementation of BSW in high school science classrooms. Participants also included four teachers who, with their students, continue to use BSW. Data sources included interviews, classroom observations, and relevant artifacts. Contrary to what often is advocated as a major benefit accruing from the integration of authentic scientific tools into precollege science teaching, classroom enactments of BSW lacked elements of inquiry and were teacher‐centered with prescribed convergent activities. Students mostly were preoccupied with following instructions and a focus on science content. The desired and actual realizations of BSW fell on two extremes that reflected the disparity between scientists' and educators' views on science, inquiry science teaching, and the related roles of technological tools. Research on large‐scale adoptions of technological tools into precollege science classrooms needs to expand beyond its current focus on teacher knowledge, skills, beliefs, and practices to examine the role of the scientists, researchers, and teacher educators who often are involved in such adoptions. © 2010 Wiley Periodicals, Inc.

Effect of Intermittent Kangaroo Mother Care on Weight Gain of Low Birth Weight Neonates With Delayed Weight Gain

Objective: To evaluate intermittent Kangaroo Mother Care (KMC) with additional opportunities to breastfeed on weight gain of low birth weight (LBW) neonates with delayed weight gain. Methods: 40 LBW neonates were followed to see whether KMC with additional opportunities to breastfeed improved weight gain. Results: In the KMC group, the mean age of regaining birth weight was significantly less (15.68 vs. 24.56 days) and the average daily weight gain was significantly higher (22.09 vs. 10.39 g, p < .001) than controls. Conclusion: KMC with additional opportunities to breastfeed was found to be an effective intervention for LBWs with delayed weight gain and should be considered to be an effective strategy.     

Children of the sug: a study of the daily lives of street children in Khartoum, Sudan, with intervention recommendations

OBJECTIVES: The study examines street children's daily lives in Khartoum, Sudan to recommend ways to improve their conditions and to successfully assist them off the streets. METHODS: In 2000-2001, eight researchers conducted participant observation for 7 weeks; 20 groups of children engaged in role-plays and drawing activities; over 500 children participated in qualitative group and individual interviews; and 872 current and former street children were surveyed. RESULTS: Approximately half of children were 14 years old or younger. Daily life focused on eating, sucking glue-soaked rags, obtaining money, and sometimes movies or games; many children valued their freedom and relatively abundant food on the streets. Boys engaged in odd jobs, and sometimes theft, begging, or sex work. Girls had fewer work opportunities and primarily obtained money through begging and sex work. Almost half of children saw their families weekly. Children belonged to same-sex groups of common geographic origin, which shared food, shelter, and care when sick; boys' group leaders could be both protectors and aggressors. Most girls had a boyfriend who financially assisted and protected her. Girls frequently were raped by street boys, police, or other men. Children feared routine capture, beating and incarceration by authorities. Former street children were housed in large camps where abuse was common, or costly small residencies. CONCLUSIONS: Street-based services to improve children's health and safety are urgently needed. Re-integration programs may help large numbers of children voluntarily and permanently leave the streets. Advocacy campaigns and collaborative efforts with the police, judiciary and legislature should be intensified. PRACTICE IMPLICATIONS: The paper highlights important challenges facing street children in Khartoum, and provides specific recommendations for how they might be better assisted while on the streets and successfully helped off of the streets through community re-integration, rather than current (1) large-scale beating and incarceration by government authorities, or (2) small-scale and costly residential housing by NGOs. The findings have already been used in a sustained advocacy campaign that has resulted in a number of positive legislative changes for street children, such as parliamentary endorsement of a new bill that improves street children's legal status.
