    An accelerated stability study was performed on diclofenac sodium controlled release matrix tablets (MT20,MT33,MT34,MT33p,MT34p ) containing natural gums, semi-synthetic gum , Eudragit L100,and hydroxypropylmethylcellulose (HPMC).Drug content was found to be in the range of 90-105% in all the five matrix formulas. Applying out of stability trend rules (OOT), the best formula was found to be MT33 which contained Guar gum 15%, and gum Arabic15%. No changes in physical appearance, or organoleptic properties were observed. Microbiological tests for the five matrix tablets were evaluated (1). No growth (bacteria or fungi) was detected, in preserved or non-preserved formulas despite of the gum content in these controlled release tablet

    Suitability of viscosity measurement methods for liquid food variety and applicability in food industry - A review.

    Although there are several approaches to measure viscosity of liquid foods in the literature, the successful selected technique depends on the specific product and the functional characteristics that need to be analyzed. Accordingly, it is not an easy task for food technologists to determine the suitable approach to be used. Therefore briefing the existing methods, working principles, advantages, limitations and their successful applications for well known published articles, may enable the researchers to choose the optimum approach. The intensive review revealed that the most commonly used viscosity measurement devices are capillary flow viscometers, orifice type viscometers, falling ball viscometers, and rotational viscometers. Glass capillary viscometers are widely used for measuring low to medium viscosity of Newtonian fluids. In order to measure the viscosity of difficult fluids like those having large particles non-conventional geometries such as mixer viscometry method is used. Tube viscometer method which might be considered as a wide-bore capillary viscometer with a special capability to handle suspensions is currently used to determine rheological behaviour of a product after a thermal treatment. Scraped surface heat exchangers (SSHE) are widely used in food industry for thermal treatment of very viscous food products. Mass detecting capillary viscometer is a new technique to measure the viscosity of milk and soymilk products. In order to measure the viscosity of food stabilizers coaxial viscometers are recommended. Also, possibly the best known of the orifice viscometers in the food industry is the dipping-type Zahn viscometer. Finally, it could be inferred that the viscosity ought to be independent on the instrument, so different instruments will yield the same results, but this is a theoretical concept and different instruments rarely yield identical results

    The principle of double jeopardy versus the principle of condonation: revisiting the Supreme Court’s decision in Nigerian Army v Aminun Kano

    Get PDF
    The Constitution of the Federal Republic of Nigeria 1999 (as amended) guarantees the rights of every person in Nigeria, including persons accused of the commission of any crime. These rights are classified as ‘fundamental rights’, and they include: the right not to be subjected to double trial for the same offence, popularly referred to as right against double jeopardy2 and the right not to be tried for an offence for which one has been pardoned.3 These two rights formed the bedrock of the decision of the Supreme Court in Nigerian Army v Aminun Kano.4 This paper critically examines and reviews the decision and observed that had the Supreme Court considered the meaning of double jeopardy under the Constitution of the Federal Republic of Nigeria, on the one hand, and condonation and pardon on the other, the court would have discovered that these triumvirate concepts do not exactly mean the same thing and consequently may have varied legal outcomes when applied, and as such, the court may have provided a different reason for their judgment in the case. This paper finds that since the principle of the right against double jeopardy requires a judicial trial and a judgment to inure, while pardon and condonation is wholly administrative action, the principle of double jeopardy should never have been invoked in the case under review because there was no prior judicial decision that exculpated or incriminated the respondent. The paper recommends that in future, if the Supreme Court is faced with the same scenario, it should make a clear distinction between the principles of right against double jeopardy and pardon and condonation so as to clarify the jurisprudential perspectives of these principles.Keywords: Judicial, Double Jeopardy, Condonation, Pardon, Court Martial, Fundamental Rights, Constitutio

    Effect of hydrocarbon presence and properties on the magnetic signature of the reservoir sediments of the Catcher Area Development (CAD) region, UK North Sea

    This paper presents a detailed study investigating the effect of hydrocarbon presence on magnetic mineral diagenesis in sediments from the Catcher Area Development (CAD) region, UK North Sea, between 1,000 and 1,500 m (True Vertical Depth Sub-Sea). Magnetic analysis of core samples from hydrocarbon fields of the region and nearby dry-well sandstones (background) was carried out to determine if their signatures can serve as a proxy for understanding petroleum reservoir systems. From the background samples, nanometric and micron-sized magnetite, hematite and titano-iron oxides, were identified. Hydrocarbon presence in the reservoir sediments was found to diminish the iron-oxide signature and favour the precipitation of hexagonal pyrrhotite, siderite and potentially vivianite, lepidocrocite, greigite and paramagnetic iron sulphides. Hexagonal pyrrhotite was found at the oil-water transition zones. This relationship is possibly related to biodegradation at this interface. Siderite was found in increased abundance at shallower depths within the reservoir, which we attribute to hydrocarbon vertical migration and biodegradation. The interbedded shales also experienced significant magnetic mineral diagenesis that depended on its proximity to the hydrocarbon plume. These findings suggest that mineral magnetism can be applied to the identification of oil-water transition zones, reserve estimation, production planning and the determination of hydrocarbon migration pathways. It also suggests that mineral magnetic methods can be used to estimate the timing of hydrocarbon migration

    Petrological and structural evolution of basement rocks around Guga, Katsina State, northwestern Nigeria

    Get PDF
    Lithological characterization and structural assessments of basement rocks around Guga, Katsina State was carried out to understand their geologic evolution and deformational history better. Field and petrographic studies were utilized in characterizing macrostructural, textural, and mineralogical components. Migmatite, banded and augen gneisses, schist, quartzite, and granite constitute the major lithologic units in the study area. Migmatite and the closely related banded gneiss are recognized as igneous-derived metamorphic rocks of Eburnean to early Pan African. In contrast, the augen gneisses are metamorphosed analogues of earlier banded gneiss that were intensely deformed within a ductile shear zone during the middle stages of the Pan African. Similarly, the schist and interbedded quartzite were emplaced during this period, subsequently forming part of the Malumfashi supracrustal cover, related to simple ensialic graben-like structural development. The granitic intrusions represent the youngest rock units in the mapped area, resulting from the magmatic activity of the Pan-African orogeny. Structural analysis suggests the mapped area was affected by two-phase deformation events (D1 and D2). The D1 deformation represents a regional, fabric-forming compressional event, while D2 is a localized deformational event associated with the development of a local shear zone linked to the Kalangai fault system (KFS)

    A study was carried out to investigate the removal of chromium (VI) ion from chromate solution using deacetylated chitin extracted from mussel shell. Mussel shells were obtained from Gubi dam in Bauchi, Nigeria and chemical method was used to extract chitin and then chitosan from these shells. A batch adsorption study was used to generate data for kinetic modelling. Out of the four kinetic models tested, the adsorption process was found to follow the pseudo-second order kinetic model with an R2-value of 0.9997; The process was physical with a free sorption energy of 0.224 kJ/mol. Also, the enthalpy of adsorption was -67.295 kJ/mol K and the Gibbs free energies were all negative, thus the process is spontaeneous and exothermic.

    BACKGROUND: The Kurds as an ethnic group are believed to be a combination of earlier Indo-European tribes who migrated and inhabited a mountainous area thousands of years ago. However, as it is difficult to describe the precise history of their origin, it is necessary to investigate their population relationship with other geographical and ethnic groups. RESULTS: Seventeen Short Tandem Repeat markers on the Y chromosome (Y-STR) included in the AmpFLSTR™ Yfiler™ PCR Amplification Kit (Thermo Fisher Scientific, USA) were used to type DNA samples from the Sorani (Central) Kurdish population in Sulaymaniyah province. One hundred fifty-seven haplotypes were obtained from 162 unrelated male individuals. The highest and lowest gene diversities were DYS385a/b (GD = 0.848) and DYS392 (GD = 0.392), respectively. The haplotypes were used to predict the most likely haplogroups in the Sulaymaniyah population. CONCLUSION: Haplogroup prediction indicated predominance (28%) of subclade J2 (44/157) in the Sorani Kurds, northeast of Iraq. The pairwise genetic distance results showed that the Kurdish group clustered along with Asian populations, whereas the furthest countries were Europeans and Africans.
