Linear Form of 3-scale Relativity Algebra and the Relevance of Stability

We show that the algebra of the recently proposed Triply Special Relativity can be brought to a linear (ie, Lie) form by a correct identification of its generators. The resulting Lie algebra is the stable form proposed by Vilela Mendes a decade ago, itself a reapparition of Yang's algebra, dating from 1947. As a corollary we assure that, within the Lie algebra framework, there is no Quadruply Special Relativity.Comment: 5 page

Derived Models for the Prediction of Cole’s and Dip Parameters for Velocity Gradients Determination in Open Natural Channels

Measurement of vertical velocity in open channel hydraulics is a very reasonable exercise that attracts peculiar results in stream flow. Observations were made on set of values obtained from calibration of models on continuous longitudinal stream flow. They showed that, there emanated effects of eddy currents. The exercise is characterized by downward trend in the velocity gradient resulting in a dip. However, at the early stage of flow development, a stage corresponding to the bed region, where little or no flow occurs, there had been what should be referred to as hypothetic zero flow region. There is vertical relationship between flow pattern developing and the position from the bed and free surface. Local scouring is induced around structural elements such as a bridge pier, an abutment at the lower region eddies and adjourning loose embankment areas. Occurrence is as a result of interaction between turbulent flow and sediment particles at the bed. The entrainment of sediment particles from the bed is probabilistic and definitely dependent upon flow characteristics and strongly influenced by instantaneous shear stresses developed along stream movement. The computed values of Cole's and Dip parameters for vertical velocities estimation were 0.77 and 0.78 respectively. For accurate measurement of vertical velocity profiles, a constant (א) has been introduced in models for velocity gradient determinationא) .) This coefficient has the estimated value of 3.6 - using mathematical iteration methods advanced by Jacobi and Hardy Cross. The proposed models (PIDMWLEL and PIDMWLL) are recommended to be most suitable for predicting velocity profile in open channels, when aspect ratios are greater than five (5) and ten (10).

Universal Electronic Student Course Registration Model (U-ESCRM)

Student course registration is an integral facet of university registration processes, which holistically cater for organizational resources: manpower and material. Although several approaches have been proposed in addressing student registration, this research paper provide a comprehensive approach with the aim of addressing comprehensiveness in courses registration through the integration of departmental units within the university into a single architecture framework. This architecture has the propensity in supporting organizational procedures and processes while lessening overhead costs associated with process depletions

AGRICULTURAL FINANCING POLICIES AND RURAL DEVELOPMENT IN NIGERIA

The study examined the agricultural financing policies of the government of Nigeria and effects on rural development .The study found that though the government has made serious efforts at making good agricultural policies through schemes, programmes and institutions, it has not been able to back them up with adequate budgetary allocation and financing coupled with corruption in the execution of the policies. It is recommended that for the government agricultural financing policies to achieve its target of rural development, Nigeria will need an adequate level of strategically targeted investment in agriculture, upgrade rural infrastructure, boost productivity, and increase competitiveness of the farm output, in addition to fighting corruption.Agricultural financing, policies, institutions, rural, development, International Development,

Granulometry, heavy mineral and geochemical studies of stream sediments around Bula, Dass District, Northeast Nigeria

Active stream sediments generally consist of broken-down fragments of pre-existing rocks by the action of river (stream) flow. This makes them target materials for routine geochemical surveys and provenance analysis. Fifteen (15) stream sediment samples were collected in some parts of Bula and its environs, northeastern Nigeria, in order to determine their textural characteristics, heavy mineral and elemental composition. The sediments were subjected to granulometric, heavy mineral and elemental analyses. The result of granulometric analysis show that the streamsediments are poorly to moderately well sorted, very platykurtic to leptokurtic, fine to medium grained and positively skewed. Zircon, rutile and tourmaline are the dominant heavy mineral species occurring in the sediments. The computed Zircon-Tourmaline-Rutile (ZTR) index values for the samples range from 59.18 - 83.53, indicating mineralogical maturity. The geochemical data of the stream sediment samples show that the mean contents of the trace elements [Ti (0.73 ± 0.74%), Fe (0.39±0.19%), Cr (816±639ppm), Ni (258±108ppm), Pb (48±12.37ppm) and Zn (502±126ppm)] were higher than their respective average crustal values except for Fe. Computed threshold values indicate possible mineralization containing Fe and Ti. The elements have variable spatial distribution. The study shows that the trace elements composition of the stream sediments is majorly lithogenic. Because mineralization in rocks and sediments are often characterized by considerable variation in their trace elements contents, the metal concentrations in these sediments are large enough for Ilmenite and Rutile mineralization to be suspected within the study area

Financial Reporting Quality and Financial Performance of Quoted Banks in Nigeria

The study examined the effect of financial reporting quality on financial performance of quoted banks in Nigeria using secondary data obtained from Nigeria stock exchange spanning from 2007 to 2016. Relevance of accounting information (measured by earnings and book value of equity predictive ability-EBVEP) and timeliness of accounting information (measured by audit report lag-ARL) were subjected to Hausman test and also regressed against performance variable: Price to earnings ratio -PER, Earnings yield -ENY and Dividend yield –DVY. Findings indicate a significant positive effect of EBVEP on PER and significant negative effects on ENY and DVY implying that an increase in EBVEP increases PER but decreases ENY and DVY. Similarly, a positive significant effect of ARL is found on PER and DVY but with a negative insignificant effect on ENY, implying that an increase in ARL increases PER and DVY but decreases ENY. The study therefore confirms that accounting information is value relevant and could be used for evaluation of accounting standards as well as for the investigation of the economic consequences of new accounting standards on the performance of quoted banks in Nigeria. We recommend that policy makers such as SEC, CBN, and FRCN should look into the audit report lag of quoted financial institutions in Nigeria and formulate policies to enforce compliance with the stipulated reporting requirements. This will assist in restoring investors’ confidence in financial reporting.

Leadership-Coaching Behaviour in Radiodiagnostic Practice

Background: Leadership-coaching can be utilized to find talents, develop and retain them to ensure organisational effectiveness. In healthcare, good leadership-coaching behaviour is imperative as it ensures collaboration among team members.   Objective: To determine the type of leadership-coaching behaviour utilized by leaders in Radiodiagnostic unit in two tertiary institutions in south-eastern Nigeria.   Methodology: Multifactor leadership questionnaire (MLQ) questionnaire was administered to three leaders and seventy-four subordinates in both units with the replacement of ‘I’ with ‘My supervisor’ in the subordinates’ questionnaire. SPSS version 17 was used to analyse the data.   Results: Response rate for leaders was 100% while that of subordinates was 79.4%. Responses received from leaders gave leadership behavioral pattern as transformational (87.99%), transactional (70.4%) and lassiez-faire ( 25%). From subordinates’ perspective however, it was transformational (67.9%), transactional (60.9%) and lassiez-faire (24.2%). T-test statistic indicate significant mean difference between positive responses in regard to transformational leadership behaviour from leaders and subordinates’ perspectives.   Conclusion: Leaders in radiodiagnostic units utilize more of transformational leadership-coaching behaviour than other forms.   &nbsp
