The second highly oligophagous species associated with Lebanese thistles was C. cylindrica, which was reared from seven genera and eight species of the Cardueae. It occurred from May to August, at all altitudes. In Israel, this ¯y was also reared from Cousinia spp. (Freidberg and Kugler, 1989). In Europe, this species was also considered generalist, and was commonly reared from many Centaurea and Cirsium spp. (White, 1988; Merz, 1994). In Asia, C. cylindrica occurs in Afghanistan, Crete, Israel and Turkey (White, 1988; Freidberg and Kugler, 1989).Published as part of Knio, Khouzama M., Kalash, Sameer H. & White, Ian M., 2002, Flowerhead-infesting fruit flies (Diptera: Tephritidae) on thistles (Asteraceae), in Lebanon, pp. 617-629 in Journal of Natural History 36 (5) on pages 623-624, DOI: 10.1080/0022293001002344

    Brucellosis causes appreciable economic losses in livestock. Examination of milk and tissues from animals in Egypt for Brucella spp. showed increased prevalence rates of serologically reactive animals. All isolates were B. melitensis biovar 3. One Brucella sp. was isolated from milk of serologically nonreactive buffaloes

    Impact of lime treatment on tailings dewatering and cap water qualityunder an oil sands end pit lake scenario

    Oil sands tailings have a limited ability to dewater and can also release toxic water, so finding a cost-effective tailings reclamation strategy has been challenging. End pit lakes (EPLs) are being examined as one potential approach to reduce fluid fine tailings (FFT) inventories for the oil sands industry. This study investigated the effect of adding lime (650 to 4000 ppm) on FFT dewatering and improving cap water quality under the simulated EPL scenario. The results illustrated that a high lime dose of 3500 ppm achieved the highest FFT water recovery, decreased the cap water alkalinity at the end of the experiment (after 90 d),and increased the possibility of cation exchange (at day 0). In contrast, the degradation of petroleum hydrocarbons was slightly enhanced at low limedose of 650 ppm in comparison to high doses. In addition, the 650 ppm dose resulted in minimal change in the microbial cell counts at day 90, compared with high lime doses that resulted in a large reduction in the cell counts. Comparisons of toxicity of the FFT pore water after lime addition exhibited higher toxic effects for lime dosages >1600 ppm. Nevertheless, at all lime doses, low cap water toxicity (i.e., <1.0 Toxicity Unit; TU) at day 90 was attained (e.g. for the 3500 ppm lime dosage, toxicity was reduced from 0.83 TU (day 14) to 0.58 TU(day 90)). The low water toxicity for the cap water (day 90) can be ascribed to the reduction of cap water pH over time due to the dissolution of atmospheric carbon dioxide into cap water. In this study, the significant implications for the use of lime treatment to improve water quality in EPLs were highlighted. We provided an initial understanding of how lime treatment could benefit the long-term success of FFT remediation within EPLs as self-sustaining aquatic ecosystems in the final reclaimed landscape

    The Conflict of Balances in the Mediterranean Region and Its Repercussions on the Map of the Ottoman-European Conflict in North Africa in the 19th Century

    This paper explores the imperialist expansion in the Mediterranean basin and its influence on the Ottoman-European conflict map in North Africa during the 19th century. This era marked significant Western imperialist growth across the Mediterranean and Ottoman territories. North Africa became a key battleground where the Ottoman Empire clashed with European powers competing for colonies in the region. Following the Berlin Conference of 1878, the Ottoman Empire recognized the strategic importance of North Africa in resisting European colonial ambitions, particularly their efforts to access Central Africa's resources by exploiting Ottoman territories. European nations, while united in their imperialist goals, competed fiercely due to divergent interests, leading to international conflicts and shifts in regional balances. This research aims to analyze the nature and background of imperialist expansion in the Medi terranean and its implications for the Ottoman-European conflict. Using a methodology combining deconstruction, historical analysis, and comparative studies, the research draws on Ottoman documents, newspapers, and a range of Turkish, Arab, and Western sources for an objective examination. The findings highlight two key conclusions: first, the imperialist expansion in the Mediterranean was deeply rooted in crusading colonial motives aimed at controlling global resources; second, North Africa played a pivotal role in shaping regional and international dynamics in the late 19th century. © 2025, J.

    Background: It is essential to understand the aetiopathogenesis of gallstone disease. This study was undertaken to determine the chemical composition of gallstones from patients living in Al-Jouf Province of Saudi Arabia. Methods: This was a descriptive study where 46 gallstones from Al-Jouf Province of Saudi Arabia were analysed by semiquantitative titrimetric and colourimetric methods. The proportion of different types of gallstones was described using 95% confidence interval based on exact method. Results: Gallstones were found more frequently in female patients (60.9%) than males (39.1%), and these stones were composed of pure cholesterol (54.3%), pure bilirubin (2.2%), or mixed stones (43.5%). The most common chemical constituent was cholesterol (82.6%), while bilirubin was seen in 26.1% of the stones. Calcium was present in 32.6% of the stones in the form of calcium salts of bilirubin and carbonate. Bilirubin-containing stones were slightly more frequent in males than in females, while cholesterol-containing stones were less frequent in males. Conclusion: The findings indicate that gallstones in the Al-Jouf Province develop more frequently in the age group of the third decade of life, with more risk among females than males, and are predominated by cholesterol together with calcium bilirubinate and calcium carbonate
