This paper aims to present the components' characterization and condition assessment of an important deteriorated Mamluk-illuminated paper manuscript housed in Al-Azhar Library, Egypt.

Different analytical techniques used in this study were the portable digital optical microscope, stereomicroscope, scanning electron microscope with EDX (SEM.EDX), portable X-ray fluorescence (pXRF), X-ray diffraction (XRD), pH measurement and Fourier transform infrared spectroscopy (FTIR).

The results obtained by different microscopes showed that the gilding in the surface of illuminated paper sheets was performed with gold leaves. Additionally, these microscopes revealed that the illuminated paper manuscript has different aspects of deterioration such as adhered dirt, staining, some micro-cracks, cracks and detachment of some parts in some illuminated areas. The results of elemental analysis by EDX, portable XRF and XRD analysis showed that the orange red pigment is red lead (Pb₃O₄), blue pigment is azurite (2CuCo₃.Cu (OH)₂), and the gold layer is has consisted of brass alloy (Cu-Zn) with a small amount of gold element (Au). The pH measurement stated that the historical paper in the acidity level. The ATR-FTIR analysis also revealed the oxidation of cellulose. Moreover, it was found from ATR-FTIR that Arabic gum was used as a binder for the pigments.

This study presents the important results of analytical methods used for condition assessment and identification of the components of an important Mamluk-illuminated paper manuscript, where these results referred that the studied paper manuscript had different aspects of deterioration. The conservation steps either conservation treatment or preventive conservation are urgently needed in future studies.

This study aims to evaluate the state of preservation of one of the most famous manuscripts dated back to the 15th century using some analytical techniques to identify the manuscript components, explain its deterioration mechanisms and produce some solutions for conservation processes in future studies.

The analytical techniques used were visual assessment, digital microscope, scanning electron microscope (SEM) with EDX, pH measurement, attenuated total reflection – Fourier transform infrared spectroscopy (ATR/FTIR) and cellulose crystallinity.

Stains, missed parts and scratching were the most common aspects of deterioration. Some insects were observed by digital microscope. The SEM showed that linen fibers and goat skin were used to manufacture paper sheets and leather binding. Energy dispersive X-ray analysis proved that niobium and tantalum were added during the manufacture of paper sheets. Carbon black ink was the main writing material. The other pigments used were cinnabar in red ink, gold color from brass and blue color from lapis lazuli. FTIR analysis proved that some chemical changes were noticed. Low crystallinity of the historical paper was obtained. There was a reduction in the pH value of the historical bookbinding.

The importance of the analytical techniques used to detect the main components, forms and mechanism of deterioration of the studied manuscript. The elements of niobium and tantalum were added to paper sheets, which protected them from deterioration. The insects such as house flies and Sitophilus granarius were found in the manuscripts.

This study aims to focus on the main materials used in consolidation processes of illuminated paper manuscripts and leather binding.

For each material, chemical structure, chemical composition, molecular formula, solubility, advantages, disadvantages and its role in treatment process are presented.

This study concluded that carboxy methyl cellulose, hydroxy propyl cellulose, methyl cellulose, cellulose acetate, nanocrystalline cellulose, funori, sturgeon glue, poly vinyl alcohol, chitosan, chitosan nanoparticles (NPs), gelatin, aquazol, paraloid B72 and hydroxyapatite NPs were the most common and important materials used for the consolidation of illuminated paper manuscripts. For the leather bindings, hydroxy propyl cellulose, polyethylene glycol, oligomeric melamine-formaldehyde resin, acrylic wax SC6000, pliantex, paraloid B67 and B72, silicone oil and collagen NPs are the most consolidants used.

Illuminated paper manuscripts with leather binding are considered one of the most important objects in libraries, museums and storehouses. The uncontrolled conditions and other deterioration factors inside the libraries and storehouses lead to degradation of these artifacts. The brittleness, fragility and weakness are considered the most common deterioration aspects of illuminated paper manuscripts and leather binding. Therefore, the consolidation process became vital and important to solve this problem. This study presents the main materials used for consolidation process of illuminated paper manuscripts and leather bindings.

The purpose of this research is to present an Islamic monetary theory of value by analyzing real prices and real money in terms of gold and silver in Egypt from 696 to 1517, a period of 821 years from the Umayyads to the Abbasids.

This paper adopts a quantitative empirical investigation derived from a full population of secondary data to deductively evaluate the measure and store of value functions of money, to affirm an Islamic monetary theory of value, which is also inductively researched through a qualitative interpretation of documentary and content analysis of Islamic and numismatic literature.

The Islamic monetary theory of value leads to an Islamic equation of exchange that reconfirms the outcome of this research, where a high value of money ensures low constant real prices over the long term.

The findings are based on an empirical investigation involving a single price of wheat series as a reasonable proxy for changes in wholesale commodity prices generally, which was successfully adopted by other studies.

The significance for modern monetary policy is that monetary authorities should adopt an Islamic monetary theory of value to achieve genuine monetary and price stability.

Through an Islamic equation of exchange, price stability would ensure real economic growth that protects wealth for holders of money due to a stable purchasing power, and combined with Islamic equity finance, more efficiency in allocating investible resources to increase gross domestic product and employment.

The Islamic monetary theory of value ensures that there is no transfer or confiscation of wealth through inflation, which would impart gains to the issuer due to the excessive supply of money in relation to demand.

Compared with its status in Islamic history, the mosque today has become a distinctive phenomenon, perceived as an identity vessel of contemporary Islamic architecture that conveys sacred metaphysical meanings. Since the advent of modernity Muslim societies has become increasingly secularized; the relationships of the sacred–secular and the divine-based demythologized knowledge have been deformed. The mosque was glossed over as the sole contemporary sacred edifice that bears metaphysical/Islamic connotations with cultural continuity. Its architecture, meanings and function have gone through a process of metamorphosis, particularly the state mosques. The contemporary mosque as such is facing a “semiological deterioration.” State mosques today are symbolic statements and communicative messages of their rulers’ power and national sovereignty, with a subsidiary role for worship, i.e., the sacred has turned into a secular power metaphor. This led to a state semantic confusion accompanied by a loss in the deeply rooted collective cultural codes of the sacred. The purpose of this paper is to investigate the metamorphosis of the semiological connotation of the contemporary mosque, with a special focus on grand state mosques, and its effects on the architecture of the contemporary mosque.

This paper is theoretical research (no case studies included).

The metamorphosis that the contemporary mosque is experiencing today as a religious edifice with symbolic connotations and architectural iconism is but an effect of the changes that occurred in the concept of the scared and its relationship to the secular in contemporary Muslim communities, as a result of modernity. Such conceptual changes led to altering the deeply rooted cultural codes to be replaced by new intentional codes, used today as vehicles of communication in mosque architecture, especially in grand state mosques. Contemporary state mosques with its new symbolism and semantic meanings have contributed to redefining the concept of the contemporary mosque in general.

Mosque architecture today receives a significant importance. Many conferences and awards are dedicated to celebrating this phenomenon. Attempts to define the criteria and style of the contemporary mosque architecture are mounting. However, rarely there are studies that defy such attempts in a critical manner. This research seeks to criticize such approaches by highlighting the essence of the transformation in mosque architecture and its relationship to the concepts of the sacred and the secular, from a semiological perspective.

The purpose of this paper is to identify factors associated with drinking patterns during pregnancy.

A rapid evidence assessment was undertaken, scanning multiple databases for studies examining factors associated with alcohol consumption in pregnancy. Studies were included if they stratified data according to quantity of alcohol consumed and identified relevant associated factors. Drinking patterns were classified as light/moderate and heavy/binge.

In total, 15 studies were included (N=7 light/moderate; N=15 heavy/binge drinking). Factors associated with alcohol consumption during pregnancy included: smoking, age, SES, marital status, pre-pregnancy substance use and parity. While few studies reported an association between heavy/binge drinking and maternal mental health, none of the studies included explored the association between mental health and light/moderate drinking.

Relatively few studies have looked at the association between psychological characteristics of women and their drinking patterns. There is a lack of articles examining light/moderate drinking in pregnancy compared to heavy/binge drinking. Moreover, there is marked variation in how alcohol use is measured. Further studies are needed to increase understanding of the association between psychological factors and patterns of drinking during pregnancy, and how health professionals might support women in this context.

The authors expand on previous work by examining two different patterns of alcohol consumption in pregnancy, rather than alcohol use simply as an isolated concept. The two groups were found to differ in a number of demographic and social factors. This information could be used to aid healthcare professionals in targeting specific interventions to those women most at risk.

The purpose of this paper is to attempt to provide a critical assessment of the trajectory and nature of the production of knowledge on cultural heritage on the Arab world. This evaluation of the discipline or field of cultural heritage will focus on both a historic evolution and on current practices in order to understand the nature and politics of that evolution.

The approach and research methodology adopted for this paper depends primarily on a long-term critical literature review and content analysis that took place over the past 25 years concerning key reports, journal articles, books and other publications on cultural heritage on the Arab world.

The paper's main findings centers on presenting current practices/production on cultural heritage which are divided into two categories in terms of production of knowledge: an abundant engagement with a technical sphere dominated with concern for documentation and conservation technology of cultural heritage; and a scarce engagement with epistemological and theoretical spheres that delves into processes of cultural heritage definition, consumption and continuity in the Arab world.

The paper attempts to engage in and commence a much-needed wider discussion on the historical transformation concerning knowledge production on cultural heritage in the Arab world and its related practices and processes. The paper emphasizes the significance of this engagement with theoretical spheres of conservation and calls for an expansion of such engagement in order to elevate the discourse and debate on cultural heritage in the Arab world.

The relationship between collective memory and the built environment is a complex relationship. Though the concept of memory is fragile, the maintenance and continuation of urban memory are essential to maintain groups' identities and to support the sense of place and place attachment between community members and the architectural settings they use and/or reside in. Preserving the physical aspects of buildings, spaces and settings that are linked with memory, is important to preserve the memory, however, the mere preservation does not guarantee the continuation of memory. The maintenance and continuation of memory is a process that depends on several factors, where the preservation of the physical aspects is only one among several. This paper aims at a better understanding of the intricate relationship between collective memory and the built environment, focusing on the processes of formation, stimulation and consolidation of memory. The paper sheds the lights on historic houses that are embedded with significant meanings and memories to their social contexts. It claims that historic houses can easily shift from ‘potential cultural memory' to ‘actual cultural memory' that could act as pillars of memory to their surrounding community, if the conservation process is done comprehensively, that is to include not only the physical and spatial aspects of memory but also to tackle the social dimensions of memory as well. The paper is organized into three sections: the first investigates the memory formation process, focusing on the social and the spatial dimension of memory, then the second investigates the possible channels to memory stimulation and consolidation, and finally, as a case study, the third section investigates the memory of two historic houses in Cairo, Egypt. The review of the works undertaken in the two houses highlights the difference and the distance between the concept of restoration and the essence of conservation. Findings yielded that, urban memory is an important aspect of cultural heritage that should to be captured and preserved for current and future generations, an aspect that is missing in local conservation approaches. Moreover, to be maintained, urban memory needs physical, social and moral props.

The purpose of this study is to explore the potential of social media as a framework for people-centered heritage. With a focus on the interpretation and display of heritage by online communities, this paper aims at providing insights into the social production of heritage – the social co-construction of meanings of everyday landscape and the making of the collective and local identity.

This paper proposes a methodological roadmap for the digital ethnography of everyday heritage. It reveals (1) the fundamental principles according to which people make value judgments and associate meanings to the urban landscape, and (2) the role of online communities in conveying collective identity and heritage values within the community realm. As a case study area for the implementation of the proposed method, three Facebook community group pages for Tripoli, Lebanon were chosen. The posts and comments were translated into English and uploaded to NVivo 12 plus and a deductive thematic approach to qualitative data analysis was applied. The data was coded into three main nodes: the actors, the tangible assets and the value registers.

Results show that Facebook users are concerned with environmental equality, common interests, utility, right to the city and representativeness, while the beautification of heritage is often perceived as a threat to these values.

This investigation goes beyond heritage attributes (what) and values (why) to examine how values are assigned by local communities. It provides a comprehensive understanding of value judgment and the rationale and arguments used to justify positions and mobilize online community members in order to contribute to the digital co-construction of everyday heritage.
