Control of Meloidogyne incognita (kofoid and white) chitwood (root-knot nematode) of Lycopersicon esculentus (tomato) using cowdung and urine
U Abubakar, T Adamu, SB Manga
African Journal of Biotechnology , 2004,
Abstract: Screenhouse experiments were conducted to test the efficacy of cowdung and urine separately and in combination in the control of root-knot nematode of tomato. Equal quantities of cowdung, urine and their mixture were separately made up to one litre with autoclaved soil. Two weeks old seedlings of tomato raised in autoclaved soil were transplanted into soil manure mixture and inoculated with 1,000 second stage larvae of Meloidogyne incognita race I. Treatments were completely randomized and effects assessed based on plant height, dry weight, extent of galling and the nematode multiplication factor. Results obtained showed that cowdung, urine, and their mixture produced significantly higher result than the untreated control. Similarly, the mixture of urine and cowdung, produced significantly higher results than the separate treatments.

Abstract: Infection with cytomegalo virus (CMV), especially in pregnancy may cause pregnancy complications such as congenital infection, non-hereditary deafness, intrauterine growth restriction and other high defects. This study was to evaluate the prevalence of CMV in pregnant women attending Antenatal Clinics at Maryam Abacha Women and Children Hospital (MAWCH) and Sokoto Specialist Hospital (SSH). The study enrolled 90 pregnant women (age range: 16-45 years old) and data on demographic and life styles obtained using structured questionnaire. Serum samples were assayed using CMV Ig-G EIA kit. Out of the 90 pregnant women examined, 88(97.8%) had IgG protective antibodies to CMV while 2(2.2%) did not have protective antibodies. The prevalence rate of 2.20% was obtained in pregnant women that did not have the protective CMV IgG antibodies and were in the age range of 16-30 years old. They were also found to be in their second trimester, which could have increased the risk of intrauterine transmission. The risk factors for CMV were observed to have been significantly (P > 0.05) correlated with the socioeconomic status, the levels of CMV Ig-G antibodies, stage of pregnancy as well as the symptoms of pregnancy complications observed in the study population while they were insignificant (P < 0.05) in the case of number of previous pregnancies. The outcome of effects on the fetus was usually fatal and irreversible. Therefore, all pregnant women should scrupulously consistently adhere to routine infection control precautions.

African Journal of Biotechnology , 2008,
Abstract: The present study was conducted to determine the prevalence of Listeria monocytogenes in smoked fish in Sokoto, Nigeria. A total of 115 different species of smoked fish from the various retail outlets and market places within the metropolis were analysed for the presence of L. monocytogenes using ISO culture method. Out of the 115 samples analysed, 29 (25%) were positive for L. monocytogenes. Other Listeria species isolated in this study are L. grayi 13 (11%), L. innocua 10 (9%) and L. ivanovi 15 (13%). The remaining 48 (42%) of the sample were negative for Listeria species. The study shows that L. monocytogenes and other Listeria species are common contaminant of smoked fish, and this may pose serious public health implications.
On the Geometry of Cotangent Bundles of Lie Groups
Bakary Manga
Mathematics , 2015,
Abstract: Lie groups of automorphisms of cotangent bundles of Lie groups are completely characterized and interesting results are obtained. We give prominence to the fact that the Lie groups of automorphisms of cotangent bundles of Lie groups are super symmetric Lie groups. In the cases of orthogonal Lie lgebras, semi-simple Lie algebras and compact Lie algebras we recover by simple methods interesting co-homological known results. The Lie algebra of prederivations encompasses the one of derivations as a subalgebra. We find out that Lie algebras of cotangent Lie groups (which are not semi-simple) of semi-simple Lie groups have the property that all their prederivations are derivations. This result is an extension of a well known result due to M\"uller. The structure of the Lie algebra of prederivations of Lie algebras of cotangent bundles of Lie groups is explored and we have shown that the Lie algebra of prederivations of Lie algebras of cotangent bundle of Lie groups are reductive Lie algebras. We have studied bi-invariant metrics on cotangent bundles of Lie groups and their isometries. The Lie algebra of the Lie group of isometries of a bi-invariant metric on a Lie group is composed with prederivations of the Lie algebra which are skew-symmetric with respect to the induced orthogonal structure on the Lie algebra. We have shown that the Lie group of isometries of any bi-invariant metric on the cotangent bundle of any semi-simple Lie groups is generated by the exponentials of inner derivations of the Lie cotangent algebra. Last, we have dealt with an introduction to the geometry the Lie group of affine motions of the real line $\mathbb R$, which is a K\"ahlerian Lie group.
Functional Diversity of Mycorrhizal Fungi Has Differential Effects on Salinity Tolerance of Acacia seyal (Del.) Seedlings  [PDF]

Open Journal of Soil Science (OJSS) , 2017, DOI: 10.4236/ojss.2017.711023
Abstract: Acacia seyal is a leguminous plant that plays an important role in the ecosystem of Sahelian zone by producing gum, wood and fodder. The growth of A. seyal is subject to many constraints as salinity which can affect the development of this tree. Therefore, soil microorganisms can help A. seyal to better tolerate the effects of negative environmental stresses. The contribution of arbuscular mycorrhizal fungi (AMF) to the salt tolerance of A. seyal, was evaluated by testing the effects of eight different arbuscular mycorrhizal fungi (AMF) isolates in the performance of A. seyal seedlings subjected to different levels of salinity (0, 340 and 680 mM). The results based on growth parameters of shoot and root parts, shoot mineral N, P, K and Na content as well as survival rates and mycorrhization showed that AMF improved mineral nutrition of A. seyal seedlings during salt stress. The combination between AMF and salinity provided evidence that the efficiency of AMF isolates were variable in improving mineral nutrition and mortality rate for A. seyal seedlings related to the level of salt stress. However, the effects of inoculation were variable depending to the AMF isolate associated with seedlings and the level of salinity, suggesting that interactions between plants and AMF can be modulated by both AMF diversity and the type and level of abiotic factors. Rhizophagus intraradices was more efficient at 680 mM NaCl in plant growth and mineral uptake while Glomus deserticola did not promote a better plant development than most of the other species inoculated to seedlings.

Bayero Journal of Pure and Applied Sciences , 2011,
Abstract: Two pot experiments were carried out in the screen house of the Faculty of Agriculture Bayero University Kano (Latitudes 80 421N and 90301N) during the wet and dry seasons of 2008/2009 to investigate the effects of Sowing Media and Gibberellic acid (GA3) concentrations on the growth and seedling establishment of three ornamental plant species. The treatments consisted of three sowing media (Top soil TS, mixtures of Top soil plus Poultry manure TS+PM and Top soil plus Sawdust TS+SD) in the ratio of 2:1, three GA3 concentrations (0, 100 and 200ppm) and three plant species (Bougainvillea, Ixora and Rose); factorially combined and laid out in a completely randomized design with four repetitions. The results indicated that TS+SD medium gave significantly (P<0.05) higher number of roots and root lengths per plant while the least was with TS+PM medium. TS and TS+SD media were significantly higher than TS+PM medium in terms of root fresh weight and root dry weight per plant. Application of GA3 at 100ppm compared to 0 and 200ppm concentrations gave significantly (P<0.05) better responses for all the root characters. The same trend was true for Bougainvillea compared to Ixora and Rosa. Hence, based on the outcomes of this experiment, combinations of TS+SD medium and GA3 at 100ppm concentration are recommended for better root establishment, growth. and development in relation to the three plants under study.

The results indicated that TS and TS+SD gave significantly (P<0.05) greater number of days to bud break, leaf area, leaf fresh weight and leaf dry weight per plant. Application of GA3 at 100ppm gave higher value of all the characters studied except number of days to bud break, where no significant difference was observed among the different concentrations. Bougainvillea was significantly (P<0.05) higher than the other plants in all the characters except days to bud break. The Combination of TS+SD medium and GA3 at 100ppm concentration is recommended for the good growth and development of the shoot characters.
The legacy of Luria and school neuropsychology
Dionisio Manga,Francisco Ramos
Psychology, Society & Education , 2011,
Abstract: This article reviews the history of neuropsychology applied towork with children. Several authors have advocated for the application of neuropsychology to the school centres, a specialty some have called “school neuropsycology”. Since the term was initially introduced (Hynd & Obrzut, 1981), considerable advances have arisen regarding the field and professional identityof this specialty. Luria’work continues to have a strong international influence. Luria has served for neuropsychological understanding of the individual and for the professional practice. As professional activity, the school neuropsychology focuses in assessing, diagnosing, and intervening with students who are experiencing learning difficulties and/or behaviour disorders in academic setting. In recent years, a comprehensive neuropsychological assessment for intervention is recommended within a school setting. Newer neuropsychological assessment procedures for children represent innovative applications of Luria’s conceptualmodel. Research and advances in neuroimaging allow us to view how the developmental brain changes.
Large historical eruptions at subaerial mud volcanoes, Italy

Natural Hazards and Earth System Sciences (NHESS) & Discussions (NHESSD) , 2012, DOI: 10.5194/nhess-12-3377-2012
Abstract: Active mud volcanoes in the northern Apennines, Italy, currently have gentle eruptions. There are, however, historical accounts of violent eruptions and outbursts. Evidence for large past eruptions is also recorded by large decimeter rock clasts preserved in erupted mud. We measured the rheological properties of mud currently being erupted in order to evaluate the conditions needed to transport such large clasts to the surface. The mud is well-characterized by the Herschel-Bulkley model, with yield stresses between 4 and 8 Pa. Yield stresses of this magnitude can support the weight of particles with diameters up to several mm. At present, particles larger than this size are not being carried to the surface. The transport of larger clasts to the surface requires ascent speeds greater than their settling speed in the mud. We use a model for the settling of particles and rheological parameters from laboratory measurements to show that the eruption of large clasts requires ascent velocities > 1 m s 1, at least three orders of magnitude greater than during the present, comparatively quiescent, activity. After regional earthquakes on 20 May and 29 May 2012, discharge also increased at locations where the stress changes produced by the earthquakes would have unclamped feeder dikes below the mud volcanoes. The magnitude of increased discharge, however, is less than that inferred from the large clasts. Both historical accounts and erupted deposits are consistent in recording episodic large eruptions.
