Opis:
Jumeirah (Dubai) is one of the most important sites for the understanding of the Abbasid period in eastern Arabia. At the same time, it is severely understudied and the small number of publications available on the subject situates Jumeirah on the margins of academic debate about the region in the Islamic period. This paper aims to prompt discussion on Jumeirah by presenting an overview of the site, a summary of archaeological research and a preliminary study of the typology of stucco decorations. Some issues regarding problems with the reconstructions and renovations of the buildings are also raised. The study of stuccoes contributes to a better understanding of the site’s chronology, indicating its main phase of occupation to the Abbasid period and the possible existence of an earlier, pre-ninth or early ninth century phase.

Opis:
This field, petrographic and geochemical study aims at constraining the formation and diagenetic evolution of sand roses (desert roses) in interdune sabkhas in Eastern Saudi Arabia. These “roses”, which are mainly cemented by gypsum, carbonate, and clay minerals, occur as disc-shaped and spherical flower-like crystals. Sands, within the sand roses, are moderately-sorted, medium-grained, and sub-arkosic. Gypsum typically exceeds 20% of the volume of the roses, and locally gypsum is partly transformed to anhydrite. In addition to gypsum and anhydrite, early diagenetic modifications include precipitation of grain coating clay, dissolution of unstable grains (e.g., feldspar grains), and weak mechanical compaction. Iron oxide cement was formed when the sand roses exposed to the surface. The XRD and petrographic data indicate an increase in amounts of gypsum cement from the water table upward towards the sabkha surface. The sand roses also are larger and lighter in colour away from the water table. This study is expected to provide a better understanding of the mode of sand roses formation in the interdunes areas, as well as the diagenetic alterations in both phreatic and vadose zones.

Opis:
The Eastern Province of the Kingdom of Saudi Arabia (KSA) is home to almost 5,000,000 people and is a major contributor to Saudi Arabia’s economic strength. The area has experienced population growth of about 3.5% per year and rapid urbanization over the past few decades. With this increase in population has come a significant escalation in automobile traffic, which, in turn, has contributed to poor air quality in the province. Two of the major cities in the area were listed on the World Health Organization’s 2016 top 15 cities with the worst air pollution. Local studies have shown that vehicle traffic is a significant contributor to poor air quality and thus, eventually, climate change. Public transportation could alleviate some of the pollution. Unfortunately, overall past perceptions of public transportation and its negative connotations within the Saudi Arabian cultural setting have discouraged previous attempts to develop public transit services. Currently, KSA is progressing with metro works in the capital city of Riyadh and is considering what services to offer in the Eastern Province. This research involved surveying over 800 Eastern Province residents to determine whether they would use public transportation if it was offered, and what type of service they would expect. The response was positive and provided initial indications that public transportation is needed and would be utilized.

Opis:
Bioremediation is based on microorganisms able to use pollutants either as a source of carbon or in co-metabolism, and is a promising strategy in cleaning the environment. Using soil contaminated with petroleum products from an industrial area in Saudi Arabia (Jubail), and after enrichment with the polycyclic aromatic hydrocarbon (PAH) naphthalene, a Methylobacterium radiotolerans strain (N7A0) was isolated that can grow in the presence of naphthalene as the sole source of carbon. M. radiotolerans is known to be resistant to gamma radiation, and this is the first documented report of a strain of this bacterium using a PAH as the sole source of carbon. The commonly reported Pseudomonas aeruginosa (strain N7B1) that biodegrades naphthalene was also identified, and gas chromatography analyses have shown that the biodegradation of naphthalene by M. radiotolerans and P. aeruginosa did follow both the salicylate and phthalate pathways.
