  • Evaluation and Modeling of Sugarcane Harvesting and Handling Systems A Case Study: Elguneid and Kenana Sugar Estates, SUDAN

This book is intended to evaluate the sugarcane harvesting systems in the Sudan. Two types of systems are used, mechanical harvesting and loading and manual cutting with two systems of loading, namely, continuous loading and grab loading. The first part of the book covered the type of cane losses resulted from different systems of harvesting and loading in addition to transportation losses and chemical losses. The second part of the book covered the machinery used to transport the cane from the field to the mill, their failures and downtime. A model to predict the optimum machinery requirement was developed depending on the mill quota, field distance, transportation unit capacity, loading and unloading time and queuing for loading and unloading time.

  • Effect of soil compaction on shoot and root development and nutrients uptake of sesame plant

This study was conducted to assess the effect of different soil compaction levels on the establishment and growth of sesame. Four compaction levels were used, namely, 1.2, 1.4, 1.6 and 1.8 g/cm3 as well as the control (0.95 g/cm3). The average plant growth parameters were found to be increased as the compaction level is increased. At the compaction level 0.95g/cm3 the seed-soil contact is week so the plant did not absorb enough moisture and nutrients from the soil. This effect was reduced when the compaction level is increased to 1.20g/cm3. The reduction of plant growth parameters under the compaction level 1.60 g/cm3 and 1.80 g/cm3 may be attributed to inability of roots to penetrate in the deep layers to absorb moisture and nutrients. The ratio between the shoot and root mass reached its maximum under the compaction level of 1.40g/cm3. Increasing the compaction level decreased the nutrient uptake. The lowest values in the control and 1.2 g/cm3 levels indicate that some compaction is needed to give a good seed-soil contact so as to be able to absorb moisture and nutrients.      It can be concluded that soil compaction significantly affect plant growth, some soil compaction is needed for good seed-soil contact, but excessive compaction will impede root penetration.

Keywords: sesame; compaction, plant height, root length, shoot:root ratio.

  • Identification of Plasmodium falciparum isolates lacking histidine-rich protein 2 and 3 in Eritrea

The histidine-rich protein 2 of Plasmodium falciparum is the most common malaria antigen targeted by rapid
diagnostic tests for the specific diagnosis of P. falciparum. Recently, pfhrp2 gene deletions have been documented
in P. falciparum isolates from South America and some multiple endemic countries in Africa and Asia. Parasites
with such gene deletions can produce false negative diagnostic results using HRP2-based rapid diagnostic kits. In
the present work, the prevalence of P. falciparum parasites lacking pfhrp2, pfhrp3, which produces a second P.
falciparum antigen that is recognized by PfHRP2 -based rapid diagnostic tests, and their flanking genes was
evaluated in 135 P. falciparum isolates from Gash Barka region and in 9 isolates from Debub region, in Eritrea. In
the analyzed samples, 56% (81/144) of isolates were pfhrp2/pfhrp3 positive, while 9.7% (14/144) showed deletion
of exon 2 of pfhrp2 gene and 43% (62/144) of isolates lacked the pfhrp3 gene. These results suggest that
the pfhrp2 and pfhrp3 deletion phenomenon is present in a considerable proportion in the study areas, thus
making the HRP2/3 based rapid diagnostic tests not completely reliable for malaria diagnosis in Eritrea.

  • مسؤلية الطفل عن أفعالة في الفقة والقانون

مستخلص الدراسة 

تتم عبر سطور هذا البحث الاسترشاد والاستدلال بان هنالك فطرة خلق الله عليها النفس البشرية وهي الاطوار التي تتطور ونمو البشر منذ مهدهم وحتي مماتهم، وتعرضت الي بعض هذة الاطوار بتسلسل في أقسام هذا البحث الذي قسم ألي مبحثين، الأول تناولت فيه الأطوار الثلاثه التي يمر بها الطفل، والمبحث الثاني عن سن البلوغ في الفقه الإسلامي والقانون، وأتيت بآراء الفقهاء في هذه المسألة، ثم استدلات بكل المذاهب ورجحت ما اراه مناسباً حسب قوة الادلة. مقارنة مع القوانين الوضعية. وجدت ان الطفل في طورة الاول من يوم ولادتة إلي سن السابعة سن عدم التميز ليس علية اي مسؤلية تاديبية، اما في الطور الثالث طور البلوغ وبلوغة درجة النضج واصبح بحال يمكنه من تحمل التكاليف والمسؤليات. وشملت نهاية هذا البحث الخاتمة والنتائج والتوصيات
