    A Study of Certain Classes of Univalent and Related Functions.
    (UOFK, 1981) Ahuja, Adam Prakash
    In the present thesis, an attempt has been made to unify various subclasses of analytic functions which are spiral like, close to convex special close- to - convex, close to star, meromotphically close- to – star, close – to – spiral like and starlike with negative coefficients by introducing the concept of type for each of these classes. An analogous unified approach has also been made for the Robertson, and close - to – Robertson functions. Thus we study several subclasses of analytic functions which not only unify a number of classes previously studied: but also give rise to many new subclasses of univalent and related functions. Classified into nine chapters, this thesis starts with a brief survey of the subject in general: and then basic concepts and results are presented in chapter 1. The chapters 11 to v11 contain the results of our investigations on a study of certain classes of univalent and related functions with general coefficients. The remaining chapters VII, VIII and IX deal with the study of analytic functions with negative coefficients.

    Morphology and Epidemiology of Some Parasitic Cope Pods (Poecilostomatoida: Ergasilidae) From British Freshwater Fish
    (university of khartoum, 1990) Abd Elhalim, A. I.
    The morphology of the parasitic female Ergasilus sieboldi Nordmann 1832 and Neoergasilus japonicus Harada 1930 together with the free-living stages of E. sieboldi are described using scanning electron microscopy. In both species cuticular outgrowths such as setae, setules, spines, spinules and sensillae as well as the integumental pores and openings were clearly identified. Studies on E. sieboldi indicated that the first leg-bearing somite is totally separated from the cephalosome. six morphologically different nauplii of E. sieboldi were identified, in addition to five copepodidand a cyclopoid stage. Sex differentiation occurs in the fourth copepodid stage and mating of adult cyclopoid male and female occurs in water. Females with attached spermatophores enter parasitic life by finding hosts and males die. The extent of tissue damage caused by the feeding activities of E. sieboldi and N. japonicus on the gills and fins of fish, respectively, is described using light and scanning electron microscopy. Such pathology, of E. sieboldi, include epithelial cell proliferation and hyperplasia which lead to fusion of gill secondary lamellae and eventually the fusion of the neighbouring gill filaments, metaplasia and necrosis. The attachment strategy of E. sieboldi results in blockage and destruction of blood vessels and opens wounds which might facilitate invasion of pathogenic microorganisms. N. japonicus destroys the covering mucus layer and erodes the epidermis of the skin by feeding and also paves way for pathogenic bacteria and fungi, by the action of second antennae. 15 The intensity and distribution of E. sieboldi on the gills is described from four species of freshwater fish, namely Tinca tinca, Abramis brama, Cyprinus carpio and Esox luciuSi from the Middle Thames Valley in Southern England. A similar ecological study was also undertaken on N. japonicus from the fins and gills of five species of freshwater fish, namely A. brama, T. tinea, E. lucius, Rutilus and Scardinius erythrophthalmus; from the same region. • An experimental study on development and establishment of E. sieboldi on rainbow trout, maintained in an open cage uni t under field conditions, is described. In addition seasonal occurrence of the different free-living stages is studied from laboratory experiment. Results from both field and laboratory experiments indicate that E. sieboldi is reproductively active from March to October during which period fish are continually infected.

    Biochemical, Toxicological and Pharmacological Aspects of Paraphenylenediamine (Hair Dye) Poisonong
    (university of khartoum, 1996) Saad, H. A.
    The systemic toxicity of PPD was investigated in Brown hisex chicks and Albino wisterrats, at different concentration through different routes of administration. PPD was introduced to chicks at doses 140, 105, 70 and 35 mg/kg bw. While rats received70,35, and 17.5 mg/kg bw of PPD. Death occur at doses 105, 140, mg/kg bw. in chicks and at doses 35 mg/kg bw in rats within 4 and 3 h respectively. Biochemical changesaccompanied PPD exposure include· elevated level in the activities of enzymes GOT,GPT, ALP, CPK, LDH and aldolase. In addition the concentrations of urea, uric acid, creatinine were elevated with marked reduction in total proteins level. Alterations in gulcose, cholesterol, K, Mg and Ca were also observed. Haemotological changes indicafe. the occurrence of anaemia. Lesions were seen in liver, kidney, cardiac and skeletalmuscles. There was clear alteration of hepatorenal and cardiac functions. Toxic effects of single sublethal dose of PPD was maximum at 24 h in rats and 72 h in chicks, subsequently changes approached normal values, but complete recovery wasnot attained up to 120 h after administration of PPD. Chronic administration of PPD in both species was associated with biochemical and histopathological changes that indicate clear dysfunction of liver and kidney. Haematological changes showed obvious anaemia. PPD was not detected in liver, kidney and heart. This may be due to the biotransformation of PPD to metabolites in the examined tissues. The pharmacology of PPD was investigated in a number of isolated preparations, frog rectus abdominus, rat uterus, rabbit aortic strip, rat stomach strip, rat ascending colon and rat phrenic nerve diaphragm preparation. In lower doses PPD revealed neither agonistic nor antagonistic effect in these tissues. However in large doses the sensitivity of tissues to stimulant and relavant drugs was lost. This is most propably due to necrotic effect of PPD. In perfused rabbit the addition of PPD increased muscle contractility. Thiseffect was blocked by pre-addition of the antihistamine (chloropheniramine). The incubation of guinea-pig lung chops produced a substance(s) that contracr guinea-pig ileum. This stimulant effect was blocked by pre-addition of chloropheniramine. This indicates that PPD may release a histamine like substance from guinea-pig IUl:6 chops .

    Bacterial Associated with Ophthalmic Infection in Domestic Animals and Man in the Sudan
    (University of Khartoum, 1997) Kawther Ahmed Awad ; Suliman Mohamed El Sanousi
    This study was conducted with specific objectives of isolation and identification of bacteria associated with eye infection in cattle, sheep, goats, horses and man. A total of 121 samples were collected from animals and man from different localities in Khartoum State. All the bacteriological examinations were performed. According to technical standards, both Gram-positive and Gram-negative bacteria were isolated, identified and differentiated using standard biochemical reactions. Gram-positive isolates consisted Staphylococcus spp., Micrococcus spp., Streptococcus spp., Corynebacterium spp., Bacillus spp. and Listeria spp. Gram-negative bacteria were Neisseria spp., Moraxella spp., Branhamella spp., Klebsiella spp., Pseudomonas spp. and Pasteurella spp. A most peculiar thing was isolation of Moraxella osloensis from infected eye of horse similar to that discovered from human. Sheep were mainly affected by Neisseria spp. then Branhamella spp., while cattle were usually affected by Neisseria spp. Goats were affected also by Neisseria spp. Horses were mainly affected with Micrococcus spp. and humans with Staphylococcus spp. According to the local environmental conditions which were mainly dominated by dust storms, the level of infection during winter was very high.

    Response of Trogoderma granarium (Everts) and Tribolium castaneum (Herbs) to Extracts and Powders from Neemleaflets at Different Developmental Stages
    (University of Khartoum, 1999) Baleela, R. M. H.
    Hazards encountered by the application of chemical insecticides on crops, lead to the use of bioinsecticides as substitutes, particularly those of neem seeds. However the scarcity of neem seeds during the growing season showed up as a problem restricting the use of neem in crop protection. In the present work neem leaflets which are less potent than seeds, but available throughout the year were studied at different developmental stages with the assumption that one of the developmental stages could provide efficacy comparable to the seeds. These stages were young leaflets of young leaves, old leaflets of young leaves, young leaflets of old leaves and old leaflets of old leaves. Aqueous extracts and powders of these leaflets stages were tested against two serious store pests, namely Trogoderma granarium Everts and Tribolium castaneum Herbs infesting wheat grains. Results showed no significant difference between neem seed powder and water extract from one side (Standard treatment) and water extract and powder of old leaflets from young leaves on the other side in most counts made. This result confirmed the assumption above and met the objectives of this research work.
