    Particle number concentration and size distribution in Jordan (in the Middle East) is still not comprehensive. In this study, a simple aerosol portable setup was used to measure size-fractioned aerosol number and mass concentrations with different particle diameter fractions (0.01–10 µm) in different regions inside Karak city and roads connecting Amman, Madaba, Karak, and Tafila, Jordan. The mean submicron particle number concentrations (PN1) in Karak governorate, Madaba, Tafila, and Amman were 2.0 × 104 cm−3, 3.7 × 104 cm−3, 4.1 × 104 cm−3 and 5.2 × 104 cm−3, respectively. On all roads leading to Karak governorate, the mean PN1 was within 1.5 × 104–3.0 × 104 cm−3, except on Madaba-Karak Road which exhibited a lower mean concentration (6.4 × 103 cm−3). In the Amman–Madaba road, the PN1 was 4.0 × 104 cm−3. Inside the Karak governorate, mean PN1, PM2.5, and PM10 concentrations were 1.0 × 104–3.0 × 104 cm−3, 10–15 µg m−3, and 27–200 µg m−3, respectively. Considering local roads inside Karak city, the mean concentrations were 2.0 × 104 cm−3, 12 µg m−3, and 109 µg m−3, respectively. This study highlights the important need to monitor and understand aerosol number and mass concentrations not only in the Karak governorate, which is affected by various environmental factors, but also in other surrounding regions. The results provide valuable insights into air quality and its potential impact on public health and the local environment. Future research is needed to focus on long-term PM levels monitoring, identifying key emission sources, and developing strategies to mitigate air pollution. Collaboration between policymakers, researchers, and local communities is essential to create effective environmental management plans and promote sustainable practices to improve air quality in the region

    Jordan is one of the ten most water-deprived countries in the world. The scarcity of water resources is one of the main challenges facing the country considering the increasing demand on water resources due to high growth in population and improvement in the quality of life. To meet the increasing demands, the country has undertaken extensive reform and investment measures in the water sector over the past decade including the construction of several dams for irrigation, municipal uses and recharge. However, the construction of dams is costly and may have diverse social and environmental impacts. Therefore, a decision to construct a dam is typically based on its financial and economic feasibility as well as on the assessment of its social and economic impacts. This paper presents the economic feasibility of the proposed Al-Karak dam. The dam is intended for efficient utilization and management of Wadi Al-Karak flood and base flow for irrigation of Ghor Al-Mazra farm area and for possible industrial use of several Dead Sea industrial and touristic establishments. The feasibility is performed for two scenarios: one based on observed irrigation requirements and one based on analysis of irrigation requirements for the typical crop patterns. The second scenario adopts an integrated approach of water supplies from Wadi Al-Karak and the adjacent Wadi Ibn Hammad. The results indicate that the dam is feasible; however, it is recommended to evaluate the project as a component of an integrated system of two potential dams on Wadi Al-Karak and Wadi Ibn Hammad. It is believed that this integrated approach will further enhance the feasibility through efficient utilization of the base flow and floods of the two wadies

    Nabataean and Roman Survey Pottery from the Karak Plateau, Jordan

    The Karak Plateau lies at the foot of the Dead Sea in central Jordan. It has been occupied continuously from the Paleolithic and has been the sit of several cultures including the Moabite, Nabataean, Roman and Byzantine. It is thus uniquely suited to the investigation of land use and resource exploitation over time. During the Roman period, the plateau was densely populated by a variety of settlements among them small farms, large agriculture villages and military posts as well as nomadic pastoralists; thus the use of land and resources in the plateau encompassed great variability (Green 2002: 48). This study examines a corpus of Nabataean and Roman pottery collected by the Karak Resources Project during its 1995-2001 surveys of the Karak Plateau, in order to study distribution patterns of pottery in the Nabataean and Roman periods. The Karak Resources Project is an expansion of the original survey performed on the plateau by J. Maxwell Miller and Jack M. Pinkerton from 1978 to 1983 (Miller 1991); its purpose is to investigate how the inhabitants of the plateau utilized its natural resources and exploited the access to trade its central location allowed (Mattingly 1996: 349). The purpose of this study is threefold- first, to determine whether survey pottery can be used to identify assemblages which are linked to each site’s specific function (such as agricultural and military sites) second, to determine whether pottery of comparable quality and similar form was consumed across sites of differing function, and third, to establish the extent of distribution of Nabataean pottery in the Karak Plateau. Macroscopic analysis was performed upon the pottery in order to discern the type vessel as well as any use wear that may be evident such as wear on the rims of cups from drinking, scraping on the inside of bowls and pots from eating or cooking utensils or scorching on the exterior of cooking pots. The microscopic analysis of the pottery was performed by the late Dr. Otto Kopp and Mr. Robert Reynolds of the department of Earth and Planetary Sciences at the University of Tennessee. Dr. Kopp and Mr. Reynolds conducted thin section analysis on a sample of pottery from the study collection, in addition to trace element analysis using x-ray fluorescence spectroscopy, to determine the petrographic and chemical composition of clays used in the production of the pottery

    Synthesis of new tetronamides displaying inhibitory activity against bloom-forming cyanobacteria

    BACKGROUND: The increasing frequency and intensity of cyanobacterial blooms pose a serious threat to aquatic ecosystems. These blooms produce potent toxins that can contaminate drinking water and endanger the life of wild and domestic animals as well as humans. Consequently, the development of effective methods for their control is a matter of high priority. We have previously shown that some γ-benzylidenebutenolides, related to the rubrolide family of natural products, are capable of inhibiting the photosynthetic electron transport chain (Hill reaction), a target of commercial herbicides. Here we report the synthesis and biological properties of a new class of rubrolide-inspired molecules featuring a tetronamide motif. RESULTS: A total of 47 N-aryl tetronamides, including 38 aldol adducts, were prepared bearing phenyl, biphenyl, naphthyl, aliphatic and heteroaromatic groups. Some of the aldol adducts were dehydrated to the corresponding γ-benzylidenetetronamides, although satisfactory yields were obtained in only three cases (52–97%). None of the synthesized compounds were capable of blocking the Hill reaction. This notwithstanding, several aldol adducts equipped with a biphenyl substituent displayed excellent inhibitory activity against Synechococcus elongatus and other cyanobacterial strains (IC50 = 1–5 μM). Further, these tetronamides were found to be essentially inactive against eukaryotic microorganisms. CONCLUSION: Several newly synthesized biphenyl-containing tetronamides were shown to display potent and selective inhibitory activity against cyanobacteria. These compounds appear to exert their biological effects without interfering with the Hill reaction. As such, they represent novel leads in the search of environmentally benign agents for controlling cyanobacterial blooms

    This article aims to determine how product selling prices were determined at MSMEs Karak Kaliang Talua RF. Data collection used the observation method by conducting interviews with the owner, asking several questions related to his business, and documenting the results of the observation visit. Based on the visit results, this business had a reasonably small target market by marketing only entrusting products to traders in traditional markets. The owner expects a profit of IDR 5,000/0.25kg for each product, namely Karak Kaliang Talua and Roti Kariang. The owner of Karak Kaliang Talua RF sets prices based only on estimated cost prices and profit expectations. After processing the data from the interview results, it was found that there was a discrepancy between the selling price set by the owner and the profit expectations

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
