The work presented in this research consists of some solutions and suggestions to solve some of the transportation and handling problems that appear in Khartoum North Power Station (KNPS) after using the waxy Sudanese fuel oil instead of the imported fuel oil. The fuel oil system in Khartoum North Power Station (KNPS) was designed for heavy fuel oil of bunker (C) type according to the British standard. The Sudanese fuel oil is paraffin-based oil, therefore it contains relatively large amount of paraffin wax content (10 - 20%). This relatively high wax content raises the Sudanese fuel oil pour point and consequently generates problems in the fuel oil transportation process, and handling process. The characteristics features of the Sudanese fuel oil are high waxy content, non- distinctive partial refined oil products, variation in type, and relatively considerable sediments content. The transportation and handling means should be changed to overcome these problems, and to maintain the same original performance. So this research is deals with the problems associated with the transportation system, and the handling system. Handling system was divided in to two parts, the first part deals with the unloading systems, the second part deals with the delivery systems, Some of the these new modifications are suggested, to command fully the drawbacks and negative side effects resulted from the usage of the waxy Sudanese fuel oil in Khartoum North Power Station (KNPS) instead of the imported fuel oil bunker (C).

The work presented in this research consists of some modifications and suggestions to solve some of the operational problems that appear in Khartoum North Power Station (KNPS) after using the waxy Sudanese fuel oil instead of the imported fuel oil. The fuel oil system in Khartoum North Power Station (KNPS) was designed for heavy fuel oil of bunker (C) type according to the British standard. The Sudanese fuel oil is a paraffin-based oil, therefore it contains relatively large amount of paraffin wax content (10-20%). This relatively high wax content raises the Sudanese fuel oil pour point and ?consequently generates problems in the fuel oil unloading process, storage process, delivery process, and fuel oil combustion process in the burners. So this research is deals with the problems associated with the fuel oil system, which can be divided into three parts, the first part deals with the unloading areasystems, the second part of this research deals with the fuel oil storage tanks systems, and the third of this part deals with the delivery systems, Some of the new modifications are suggested, to command fully the drawbacks and negative side effects resulted from the usage of the waxy Sudanese fuel oil in Khartoum North Power Station (KNPS) instead of the imported fuel oil bunker (C).

Molecular Identification of Taenia hydatigena from Sheep in Khartoum, Sudan
Rosline James Muku,Hong-Bin Yan,John Asekhaen Ohiolei,Abubakar Ahmed Saaid,Sara Ahmed,Wan-Zhong Jia,Bao-Quan Fu 대한기생충학열대의학회 2020 The Korean Journal of Parasitology Vol.58 No.1
The cestode Taenia hydatigena uses canids, primarily dogs, as definitive hosts, while the metacestode larval stage cysticercus infects a range of intermediate hosts, including domestic animals such as goats, sheep, and pigs. Cysticercosis due to T. hydatigena has large veterinary and economic drawbacks. Like other taeniids, e.g., Echinococcus, intraspecific variation is found among the members of the genus Taenia. In Africa, few studies are available on the epidemiology and distribution of T. hydatigena, and even fewer studies are available on its genetic variation. In this study, we molecularly identified 11 cysticerci from sheep in Sudan and demonstrated the genetic variation based on the NADH dehydrogenase subunit 1 (nad1) and cytochrome c oxidase subunit 1 (cox1) mitochondrial genes. The isolates were correctly identified as T. hydatigena with more than 99% similarity to those in the GenBank database. Low diversity indices and insignificant neutrality indices were observed, with 3 and 2 haplotypes for the nad1 and cox1 genes, respectively. The results suggest the presence of unique T. hydatigena haplotypes in Sudan, as haplotypes with 100% similarity were not found in the GenBank database. With few available studies on the genetic variation of T. hydatigena in Africa, this report represents the first insights into the genetic variation of T. hydatigena in Sudan and constitutes useful data.

수단 여성의 미니스커트에서 히잡으로: 레일라 아부렐라의 『사원의 첨탑』
차희정(Hee jung Cha) 한국영미어문학회 2018 영미어문학 Vol.- No.130
This paper explores Minaret (2005) written by a muslim writer, Leila Aboulela, from a feminist perspective. This thought-provoking and disturbing novel revolves around the transforming process of a muslim woman from innocence to maturity along with her movement from Khartoum, Sudan to London, UK. The paper discusses the physical and spiritual journey of the narrator in relation to diaspora movement and cultural experience of in- betweenness. Aboulela brilliantly illustrates the religious conversion of the westernized modern woman who struggles with male characters such as her executed father, drug-addicted brother, egoistic socialist boyfriend, and immature fundamentalist lover and comes to gain religious spirituality as a redemptive power with the help of a transnational group of muslim women. In doing so, she endeavors to resist anti-Islam stereotyping and to represent a different, if not positive, portrayal of a muslim woman who is not merely victimized but independent, educated, and articulate.
