This study was developed within the framework of a broad international project, ‘Ecological water quality assessment of the Alcantara (Italy), James (USA) and Guadalfeo (Spain) rivers using bioindicators’, established by the Center for Integrative Mediterranean Studies (CIMS), a collaborative research centre consisting of the University of Messina – Italy, Virginia Commonwealth University – USA, and the University of Cordoba – Spain. The primary objective of the study was the validation of a multi-disciplinary ecological approach at different taxonomic levels for biomonitoring of the Alcantara River (Sicily, Italy) using bioindicators. This study examined the primary physical, chemical and biological features of the river through an interdisciplinary and synoptic approach using bioindicators that included riparian plant physiology, the microbial, zooplanktonic and macroinvertebrate assemblages, Coleoptera (Insecta) and river hydrology. Sampling of the river and riparian areas was conducted at sites from the river’s headwaters to the mouth. The study provided information on the ecological status of the Alcantara River along its course and tested the use of a variety of bioindicators, rather than a single biotic or physicalattribute, to determine the river’s health.

Information and knowledge management have become very crucial to the growth and development of countries around the world, including African countries. This is also true about the importance of information science education. This truth has already been accepted in Africa, including Nigeria, where the joint effort of the International Development Research Centre (IDRC) and United Nations Educational, Scientific and Cultural Organisation (UNESCO) led to the establishment of the Africa Regional Center for Information Science (ARCIS) in 1990. The primary objective set for ARCIS was for it, as a regional Center, to internationalize its processes, functions and curriculum. This paper, relying on both primary and secondary data, examines the issue of internationalization of information science education in Nigeria with practical examples reported from experiences at ARCIS. It highlights current achievements ARCIS has recorded in its internationalization efforts, challenges it faces due to the political experiences in Nigeria and competing needs of units and departments at the University of Ibadan, as well as the prospects of ARCIS internationalization efforts. In the end, it is concluded that the internationalization future for ARCIS is bright.

Day By Day

Background: The number of postgraduate students in Cardiac surgical discipline is increasing day by day with incremental proportion are measurably suffering from the unnecessary lingering of the present course curriculum. The primary objective of this study was to find out the last 5 years’ of results of Masters in Surgery course under the University of Dhaka from a student room survey. A secondary objective was to find out positive changes that could show us the way of a step toward up-gradation. Methods: It is a retrospective analysis of all examination results of Cardio-vascular & Thoracic Surgery published since January 2008 to January 2013 from the University of Dhaka with in depth interview of 11 participants. Results: 85.24% students failed to pass part-I of Masters in Surgery for Cardio-vascular & Thoracic Surgery course while, 82.18% in part-II and 71.28% failed to pass the final part. Average 2.51 attempts needed to complete each part of the designed course resulted into lingering of course duration for 42.18 months/student. In the thoracic surgery discipline the number of students alarmingly reduced up to 0% in the recent academic sessions. Conclusions: Masters in Surgery is resulting in unnecessary prolongation of the course. We should step forward to meet the next generation challenge.

Every teacher must realize that he/she needs to be highly motivated, committed, passionate, and optimistic towards his/her students as well as his/her teaching in order to create a positive and productive impact on the students and their learning outcomes. It is a proven fact that teachers who are sincere, caring, approachable, supportive and inspiring can easily enable their students to become enthusiastic, successful and creative learners. John Hattie, a proponent of Evidence Based Quantitative Research Methodologies on the Influences on Student achievement, who is also a Professor of Education and Director of the Melbourne Education Research Institute at the University of Melbourne, Australia, has noted in his study that a harmonious classroom can assist with the development of creativity as well as reduce anxiety levels amongst students. In my opinion, the primary objective of all effective and conscious teachers should be to promote a safe and healthy learning environment wherein students will feel confident, comfortable, happy and accepted. Time and again, I am convinced of the fact that only effective and conscious teachers understand, acknowledge and therefore, appreciate the significance of creating a rapport and bonding with their students for providing an education that is positive, productive and progressive. When teachers display a positive and congenial attitude towards their students, they not only make them ‘learn better, faster and deeper’ but make them self-confident and self-reliant too. Building positive, supportive, cooperative and mutually strong teacher-student relationships is the key to create a welcoming, healthy and conducive learning space in which students are enabled to thrive, prosper and go on to become what they are meant to be in life. And it is only by forging and nurturing a strong and positive relationship with their students, can teachers create a healthy and conducive learning atmosphere wherein students feel welcome, accepted, respected, loved and cared for, wherein learning becomes fun and joy. Conscious and committed teachers promote the art of positive parenting in every classroom and in every school to enable the students to become confident learners by willingly and happily shouldering the responsibility of being their ‘second parents’.When teachers teach with passion, display positive attitude towards their students and their success, and show genuine care for them, the students reciprocate with respect for their teachers, interest and love for their learning.

The Impact

IntroductionDiabetes affects more than 9% of the adult population worldwide. Patients with type 2 diabetes mellitus (T2DM) show variable responses to some drugs which may be due, in part, to variability in the functional activity of drug-metabolising enzymes including cytochromes P450 (CYP450s). CYP450 is a superfamily of enzymes responsible for xenobiotic metabolism. Knowledge must be gained on the impact of T2DM and related inflammatory processes on drug metabolism and its consequences on drug response. The aim of this study is to characterise the activity of CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP2D6, CYP2E1 and CYP3A4/5 in T2DM versus non-T2DM subjects following the administration of a cocktail of probe drug substrates.Methods and analysisThis single-centre clinical study proposes the first detailed characterisation of T2DM impacts on major CYP450 drug-metabolising enzyme activities. We intend to recruit 42 patients with controlled T2DM (A1C≤7%), 42 patients with uncontrolled T2DM (A1C>7%) and 42 non-diabetic control subjects. The primary objective is to determine and compare major CYP450 activities in patients with T2DM versus non-diabetic subjects by dosing in plasma and urine probe drug substrates and metabolites following the oral administration of a drug cocktail: caffeine (CYP1A2), bupropion (CYP2B6), tolbutamide (CYP2C9), omeprazole (CYP2C19), dextromethorphan (CYP2D6), chlorzoxazone (CYP2E1) and midazolam (CYP3A4/5). Secondary objectives will evaluate the influence of variables such as glycaemia, insulinaemia, genetic polymorphisms and inflammation. The value of an endogenous biomarker of CYP3A activity is also evaluated. The first patient was recruited in May 2015 and patients will be enrolled up to completion of study groups.Ethics and disseminationApproval was obtained from the ethic review board of the CHUM research centre (Montreal, Canada).Trial registration numberNCT02291666.

Abstract Under the national research project, dubbed Turbotech II, in which MTU Aero Engines, DLR Institute of Propulsion Technology and EADS Corporate Research Centre participate, active noise control (ANC) has been tested with a scale model fan of one metre diameter for a high bypass ratio aeroengine. MTU’s task in this project was to develop a computer code to predict the sound field in the intake duct of the fan-rig by the use of active control. The primary objective of the numerical study was to specify numbers of actuators (loudspeakers) and error sensors (microphones) and their positioning to control the harmonic sound power, radiated upstream to the duct intake. The computer model is based on the geometry of an annular or circular duct of rigid walls and infinite length, containing a subsonic axial uniform flow. The modal amplitudes of the primary sound field are input data. The actuators are modelled by acoustic monopoles. Two control algorithms have been used for achieving the control objective. The first consists simply in the reduction of the in-duct mean squared pressures. The second, so called modal control, is designed to cancel dominant modes selectively. Numerical results are presented using a typical configuration of wall mounted actuators and error sensors in the form of a number of rings uniformly distributed along the length of the intake duct. Guidelines have also been derived to design a favourable configuration of actuators and sensors. The findings of the numerical study are compared with the results of the ANC tests.
