Opis:: This study was conducted to measure the concentrations of four trihalomethane compounds (THMs) in raw, treated, and drinking water of seven water purification plants and the residential neighborhoods nearby in Baghdad. About 350 samples gathered between January and October 2017 and analyzed by the gas chromatography method. Results showed that THM annual levels in tap water ranged between 12 and 97.3 µg·l–1 in winter and summer consecutively, with a mean concentration of 60 µg·l–1, these concentrations did not exceed the level recommended by the WHO and the Iraqi standards. Statistical modeling by SPSS software for the formation of THM (the dependent factor) in the water supply network was undertaken using the measured water quality parameters (as independent factors) and utilizing multiple regression analysis. The model obtained has a high correlation (r = 0.842) and approved that the most affecting parameters on THM formation are total organic carbon, temperature, turbidity, total solids, and chlorine dose. The model that was derived may be used for the purposes of choosing appropriate THM-reduction procedures and the use of chlorine for improving the method of disinfection.

Opis:: Water transport was the earliest mode of transport in ancient Mesopotamia. Thanks to the Tigris and Euphrates rivers, which run along the whole length of Mesopotamia, and a network of canals, river transport facilitated communication, exchange, as well as cultural and military contacts between towns. This paper focuses on the riverine transport in Mesopotamia and its development from the Ubaid (5900–4200 BC) to the Neo-Babylonian period (626–539 BC). The importance of river transport in Mesopotamia is discussed, considering its role as a means of communication, exchange of goods and ideas, and a factor influencing the sociopolitical transformation in the region. Watercraft is discussed to the full extent, with particular emphasis on different types of ships and their functions. The chronological development of watercraft in Mesopotamia is also analysed based on boat models, cuneiform texts, and representations of boats in the art.

Tytuł:: The Upper Tigris Region between Rome, Iran, and Armenia

Opis:: The aim of this paper is to provide an overview of the geopolitical status of the Upper Tigris area in antiquity, with a special focus on the period between ca. 401 BCE and the 6th century CE. Despite the popular impression that this area had a distinctly Armenian character, a closer look at its history shows that it was rather a territory with many local geopolitical entities that many neighboring countries periodically fought to possess. This area was strategically significant as a transit region located on the crossroads of important long-distance communication lines. Likewise, its natural resources were undoubtedly crucial to the neighboring countries. Indeed, powerful neighbors around the Upper Tigris area, including Armenia, the Iranian kingdoms of the Parthians and Sasanians, and Rome, sought to control this area, which was often located on the fringes of their states and as such was inevitably doomed to be contested by these empires onmany occasions. This situation can be acutely seen in the conflict between Rome and the Iranian kingdoms of the Parthians and Sasanians, when northern Mesopotamia became a real battleground between the competing empires. In particular, the paper will sketch the development of the geopolitical status of several small geopolitical entities in this region—Sophene, Osrhoene, Gordyene, and Adiabene.

Opis:: Water could be some-times a source of danger on people's lives and property. Although it is one of the most important elements of life on this planet. This article define the threat of water pollution in Tigris River in Iraq. by collecting a data that generated by sensors that installed in a water pollution sensing project in Baghdad city, also this article aimed to detect and analyze the behavior of water environment. It is an effort to predict the threat of pollution by using advanced scientific methods like the technology of Internet of Things (IoT) and Machine learning in order to avoid the threat and/or minimize the possible damages. This can be used as a proactive service provided by E-governments towards their own citizens.

Tytuł:: Natural Diminishing Trend of the Tigris and Euphrates Streamflows is Alarming for the Middle East Future

Opis:: Over the last decade, numerous studies have appeared in books and journals addressing the climate change impacts on water quantity and quality of the Euphrates and Tigris River Basins. When one focused to these studies it can be seen that several studies link the Syrian uprising and subsequent outbreak of civil war to the drought. it also seems that when the current civil war is over, the most important need will be implementation of a basin wide sustainable water management policy. Therefore this requires more cmprehensive studies on current situation and future threats of the basin. Some of the researches have stated in their recently published articles that, “a severe drought occurred by human-induced climate change and a mass migration of drought-affected farmers fled to Syria’s, then the influx of migrants exacerbated unemployment and inequality in the cities, contributing to civic unrest over a nonresponsive government”. Most researchers agree that climate change contributed to the drought in Syria and civil unrest crisis. Recent studies have also noted that there has been an natural declining trend in Tigris and Euphrates Streamflows That means that changes in flow are more closely related to natural diplomacy features than with human interventions in Tigris and Euphrates Basins. All this abovementioned results are alarming invitations to all riparian states in the Middle East to create a new hydro diplomacy.

Opis:: One of the main approaches to monitoring the welfare of wild mammal populations in the wild is animal health estimation based on an analysis of their physiological parameters. To assess that for the natural felid populations, we analyzed adrenal activity level, white blood cells (WBC) counts and occurrence of seropositive reactions to different diseases. The first study was conducted in the Southwest Primorye, in natural habitats of Far Eastern leopard. Unevenly cold and snowy winters in 2010 and 2011 provided extreme natural conditions for overwintering mammals across the Russian Far East. Adrenocortical activity of leopards was significantly higher in 2011 (fecal cortisol level was 712.7 ± 92.4 ng g-1) than in 2010 (361.4 ± 80.5 ng g-1). We suggest that abundance and availability of weakened deer and carcasses could facilitate hunting for leopards and help them to avoid starvation. In the second study we used WBC counts as a health index for three felid species: Pallas cat (Daursky State Nature Biosphere Reserve, 2010), Far Eastern leopard (Southwestern Prymorie, 2011), Siberian tiger (Ussuriskii Reserve, 2010-2011). The ratio of neutrophils to lymphocytes (N:L) was used as an indicator of stress and/or disease state. Occurrence of seropositive reactions to 12 different pathogens was analyzed in all the animals after the hematological analysis. Pallas cats had the lowest N:L ratio (1.0 ± 0.1), significantly differing from leopards (42.8 ± 16.0) and tigers (24.5 ± 9.2). The N:L ratio correlated with the occurrence of seropositive reactions but not with the pathogen diversity. Pallas cats had the lowest occurrence of positive reactions to 4 pathogens: Toxoplasma gondii (12.5%), Mycoplasma sp. (12.5%), influenza A (7.1%), and feline leukemia virus (8.3%). Leopards had the highest N:L and occurrence of seropositive reactions only to 2 infections: T. gondii (16.6%) and Candida sp. (100%). On the contrary, tigers had positive responses to 6 pathogens, including canine distemper (7.7%), feline immunodeficiency virus (8.3%) and Aujeszky's disease (31%), which were not found in other cats. Values of N:L depended also on the time spent to get blood samples. In the big felid species effects of glucocorticoids on the WBC ratio (neutrophilia) were obtained in blood samples from anesthetized animals, taken more than 2 hours after capture. In Pallas cats blood samples were collected within 13 ± 2 min without anesthesia. Thus the high N:L ratio in big felids can be explained by several reasons: stress of capture, immunosuppression and a high diversity of detected infections. The present findings may have important implications for creation of effective conservation strategies of rare felid species in the wild.
