As widespread deserts is located in west and southwest of Iran plateau, dust storms form due to west andsouthwest systems over Syria or Iraq as well as Arabian Peninsula. These systems severely affect west and southwestregions. Sometimes the fine dusts transmit to central, north east, and east regions. In this study for investigating dustysynoptical patterns, meteorological data at 5 synoptic s...

This paper aims to provide a urban morphological analysis of the transformation of Saudi Arabian cities from the late 18 century onwards through a cartographical urban inventory as its basis. The paper focuses on the cartographical information about the major cities in the Saudi Arabian Peninsula associated with the period between late 18 and early 20 centuries. This study was mainly conducted ...

Rift Valley fever (RVF) is an emerging, vector-borne viral zoonosis that has significantly impacted public health, livestock health and production, and food security over the last three decades across large regions of the African continent and the Arabian Peninsula. The potential for expansion of RVF outbreaks within and beyond the range of previous occurrence is unknown. Despite many large nat...

In this study we attempted to better quantify radiative effects of dust over the Arabian Peninsula and their dependence on input parameters. For this purpose we have developed a stand-alone column radiation transport model coupled with the Mie, T-matrix and geometric optics calculations and driven by reanalysis meteorological fields and atmospheric composition. Numerical experiments were carrie...

OBJECTIVE To describe the clinical characteristics of multiple sclerosis (MS) seen in Oman and compare it with those seen in the Arabian peninsula, the rest of Asia and the Western world. METHODS A hospital based case descriptive study of MS patients, seen at Sultan Qaboos University Hospital in the Sultanate of Oman, between June 1990- June 2000. RESULTS We saw a total of 30 patients durin...

Shammah is a preparation of smokeless tobacco (ST) that is frequently used in the Arabian Peninsula, especially in Saudi Arabia. A mixture of powdered tobacco, lime, ash, black pepper, oils and flavorings, shammah in is placed in the buccal cavity or lower labial vestibule of the mouth. The user (or dipper) spits out insoluble debris. ST is linked to a number of harmful effects such as dental d...

[1] This paper analyzes MODIS 1 km albedo kernels of 7 spectral bands over Northern Africa and the Arabian Peninsula and through these kernels develops a new high quality dataset that provides a simple statistical method to scale up spectral and broadband albedos from pixel to arbitrary coarse resolution grid square for use in climate models. This dataset significantly improves characterization...

The Levant is a region in the Near East with an impressive record of continuous human existence and major cultural developments since the Paleolithic period. Genetic and archeological studies present solid evidence placing the Middle East and the Arabian Peninsula as the first stepping-stone outside Africa. There is, however, little understanding of demographic changes in the Middle East, parti...

Widespread interest in the first successful Out of Africa dispersal of modern humans ∼60-80 thousand years ago via a southern migration route has overshadowed the study of later periods of South Arabian prehistory. In this work, we show that the post-Last Glacial Maximum period of the past 20,000 years, during which climatic conditions were becoming more hospitable, has been a significant time ...

Dromedaries have been fundamental to the development of human societies in arid landscapes and for long-distance trade across hostile hot terrains for 3,000 y. Today they continue to be an important livestock resource in marginal agro-ecological zones. However, the history of dromedary domestication and the influence of ancient trading networks on their genetic structure have remained elusive. ...
