L'Ummu Musa, "madre" della tavolette talismaniche hausa
No full textQuesto volume, curato da Andrea Brigaglia e Gigi Pezzoli, e corredato da contributi specialistici di esperti internazionali, è concepito per accompagnare la mostra dal titolo “Nel nome di Dio Omnipotente. Pratiche di scrittura talismanica dal nord della Nigeria”.Il progetto trae lo spunto da due esigenze fondamentali: la prima è di natura artistica, l’altra storico-antropologica. L’intento è di presentare, con l’ausilio di un ricco apparato iconografico, materiali esteticamente accattivanti all’interno di un ampio quadro antropologico relativo alle pratiche di scrittura dellʼIslam africano contemporaneo della Nigeria settentrionale.Pur con un’enfasi sulle tavole talismaniche, la ricerca evita di adottare una separazione artificiale tra le categorie di “religione” e di “magia”, e riflette sulle varie dimensioni, esteriori ed esoteriche, delle pratiche culturali di quei popoli, come ad un insieme organico. Una testimonianza di mondo di tradizione prevalentemente sufi, apparentemente lontano ma che rimanda ad antiche pratiche protettive, divinatorie e taumaturgiche del Medio Oriente, del mondo greco-romano, della Cabala ebraica, fino all’alchimia medievale

Synthesis and study of superabsorbent properties of acryloylated starch ester grafted with acrylic acid
No full textA superabsorbent polymer has been prepared by acryloylation of starch followed by grafting with acrylic acid (AA) using Fenton's initiation system (Fe2+/H2O2). Fourier-transform infrared spectroscopy (FTIR) analyses provided evidence for starch ester formation and grafting of AA onto its backbone. Further characterization of the product was carried out using XRD, SEM and thermogravimetric (TGA) techniques. The product, which has a low yield of homopolymer and exhibits more adhesive and film forming properties than the direct method of grafting AA onto starch, was used for water absorption analysis. The neutralized product showed a remarkable water absorption capacity (127 g/g) much higher than the polymer synthezised from direct grafting
Numerical simulation of multifracture HDR geothermal reservoirs
No full textThis paper presents a three-dimensional (3D) numerical model of multifracture hot dry rock (HDR) systems using coupled thermo-hydro-mechanical (THM) modelling processes. Several numerical models are implemented in the COMSOL Multiphysics Finite Element (FE) solver to analyse the effect of fracture spacing and number on reservoir productivity. The developed multifracture HDR reservoirs employ vertical fracture systems with deviated wellbores to reflect the state of stress in deep geological formations. The models consider the geomechanical effect of fracture aperture, permeability and stiffness changes on each individual fracture during long-term exploitation of 30 years. The crucial parameters investigated concerning reservoir productivity are production temperature, thermal energy and recovery rate. The results show that both fracture number and spacing affect the productivity of HDR geothermal systems. It is clear from the results that variations of geomechanical parameters of fracture aperture, permeability and stiffness can play a crucial role in enhancing the performance of these systems.No Full Tex
An appraisal of the constitutional and regulatory mechanisms for the appointment of judicial officers in Nigeria and associated challenges
No full textThe institution to settle the dispute between individuals is a court of law manned by Judges. To nominate and appoint the judges are herculean tasks which involve processes to ensure only fit and proper persons occupy Judicial Offices. This paper examined the constitutional and regulatory procedures for the appointment of Judicial Officers in Nigeria. The study identified the problems associated with the processes of the appointment of the Judicial Officers in Nigeria. The work adopted the socio-legal research method by using the qualitative approach. There is a dearth of literature in Nigeria on how the procedure for the appointment of Judicial Officers operates practically and the real problems associated with the operation of the procedural laws. To achieve the research objectives, a semi-structured interview was used. Three specialists in the Nigerian legal profession were interviewed to find out the actual issues on the ground. The study discovered that lobbying has been entrenched in the process of the appointment of Judicial Officers in Nigeria. The research further found that the powers of the Chief Justice of Nigeria to appoint the majority of members of the recommendation body threatens the independence of the Judiciary
Isolation and Identification of Phosphate Solubilizing Bacteria from Agricultural Soils of Modoji, Batagarawa, and Umaru Musa Yar'adua University of Katsina Metropolis
No full textPhosphorus is the least mobile and available to plants in most soil conditions despite being abundant in organic and inorganic forms. Phosphate solubilizing bacteria (PSB) play an important role in supplying Phosphorus to plants in a more environmentally friendly and sustainable manner to circumvent phosphorus deficiency. This study aims to isolate and identify Phosphate solubilizing bacteria from the agricultural soils of Modoji, Batagarawa, and Umaru Musa Yar'adua University Katsina. The rhizosphere soil samples were taken from 4 distinct locations and serially diluted, and the pour plate method was employed. Gram reaction and subsequent biochemical tests for the isolates were conducted. Rhizospheric soil bacterial isolates were isolated and screened for phosphate solubilization using the National Botanical Research Institute’s phosphate growth medium (NBRIP) and Pikovskaya (PVK) medium. Results showed that total rhizospheric bacterial count ranged from (6.84x10⁷ CFU/g - 12.20x10⁷CFU/g). All twelve (12) isolates were found to be gram-negative: Pseudomonas sp. (91.7%) and Bacillus sp. (8.3%) and were observed to be positive for starch and gelatin hydrolysis test. The diameters of the phosphate solubilization clearance zones ranged from 14.5 ± 0.5 – 27.0 mm. It was concluded that these isolates can be used as plant growth-promoting agents and as biofertilizers in sustainable agriculture
An Early Numerical Prediction of the United Downs Deep Geothermal Power Project, United Kingdom
No full textThe United Kingdom has been at the forefront of testing the feasibility of hot dry rock (HDR) geothermal energy resources since the mid-1970s. Several experiments were carried out between 1977 to 1991 at the Rosemanowes site in Cornwall. After a long period of testing the project was discontinued in 1991 due to some challenges. However, investors are back on board, developing a deep enhanced geothermal system (EGS) at the United Downs in Cornwall, Southwest England. The project aims to tap the abundant thermal energy underneath Cornish granites. So far, drilling of wellbores have been completed as of June 2019, and notable progress has been made on testing. Two features make the United Downs Deep Geothermal (UDDGP) project novel: a larger wellbore separation distance of about 2,882 m and the intersection of a fault zone by both wellbores. Thus, this paper presents a new three-dimensional (3D) model based on the site's limited data to predict system performance. The model implements the coupled effect of thermo-hydro-mechanical (THM) processes using the COMSOL Multiphysics. The simulation results show that the model prediction ability agrees with the existing EGS behaviour. However, more rigorous site data is required for an in-depth analysis of the system performance.No Full Tex
The Role of Thermal Stress in Enhancing the Reservoir Properties of Enhanced Geothermal
No full textThe injection of cold fluid into a hot dry rock (HDR) formation causes temperature changes that often induce thermal stress. This will alter the reservoir properties of the rock mass and the fluid, making thermal stress central to understanding the behaviour of HDR geothermal reservoirs. In order to explore the effect of thermal stress on reservoir properties, this paper presents a new numerical model of an enhanced geothermal system (EGS) using a coupled thermo-hydro-mechanical (THM) model. Nine reservoir properties are examined: permeability, aperture, stiffness, pore pressure, effective stress, shear stress, density, viscosity, and temperature. The results show that thermal stress enhances each of these properties substantially when compared with a model without thermal stress. It is clear from the simulation that exclusion of the thermal stress effect in a model could end in an erroneous description of the system output.No Full Tex
A Survey of Salmonella Species and their Antibiotic Susceptibility Profile from Selected Wells in Katsina State, Nigeria
Full text linkThe World Health Organisation (WHO) has estimated that 1.1 billion people globally lack basic access to drinking water resources, while 2.4 billion have inadequate sanitation facilities which accounts for many water related acute and chronic diseases. The study was designed to search for the presence of Salmonella spp from wells in Dan-musa, Mani and Danja Local Government Areas of Katsina State. The distances of wells to pit laterines were measured at collection points. The organisms were detected and isolated by cultural methods using selective media and were subjected to series of biochemical tests. They were sero-grouped using seroquick grouping reagents. Antibiotic susceptibility testing was performed by disk diffusion method. All the distances measured were below the set standard of 30 meters by WHO and the Nigerian Environmental Protection Agency. Dan-musa Local Government Area had the highest mean coliform counts of 20.7cfu/ml, while Danja had least counts of 13.8cfu/ml. Out of the 300 well water samples collected, a total of 11 Salmonella strains were isolated belonging to three(3) different sero-groups (Group D, A and B). Significant statistical association (p<0.05) was found between the occurrence of these bacterial isolates and distance of wells to pit laterines. All the isolates were resistant to multiple classes of antibiotics, the highest resistance was to ceftazidime and cefuroxime, 100% each. However, the isolates were also sensitive to flouroquinolones, chloramphenicol and cefoxitin. The presence of these pathogenic bacteria from the well water samples analysed connote a serious health risk to consumers due to threat of disease and antibiotic resistance. The study accenuates the need to set standards for citing of wells away from pit latrines, provision of adequate potable water and improved sanitation
