A novel approach to modeling unstable EOR displacements

This research is aimed at developing a methodology for predicting the performance of unstable displacements in heterogeneous porous media. A performance prediction approach that integrates numerical modeling with laboratory experiments will be developed. Flow visualization experiments will be performed on laboratory corefloods using X-ray computed tomography (CT) and other imaging technologies to map the in situ fluid saturations in time and space. A systematic procedure will be developed to replicate the experimental image data with high-resolution numerical models of the displacements. 2 refs., 3 figs., 1 tab

Prediction formulae for lung function parameters in females of south eastern Nigeria.

This study was carried out to obtain normal lung function values for women in south eastern Nigeria with a view to establishing prediction equations for forced vital capacity (FVC), forced expiratory volume at the first second (FEV1) and peak expiratory flow rate (PEFR). Lung function values were measured in 600 apparently healthy Nigerian women aged between 18 and 57 years. FVC and FEV1 were significantly related to height (

Cd4 count levels and pattern of respiratory complications in hiv seropositive patients in calabar, Nigeria.

A prospective observational study was carried out to describe the pattern of pulmonary complications in hospitalized patients with Human Immune-deficiency Virus (HIV) infection at the University of Calabar Teaching Hospital, Calabar between January 2005 to December 2006. One hundred and twenty-four patients which consists 60 males and 64 females, aged between 20 – 60 who met the inclusion criteria formed the subjects for the study. The mean age of the subjects was 34.60+1.2 years. A structured questionnaire was used to obtain the demographic data, clinical information and CD4 lymphocyte count. Radiological analysis of chest was done with the chest X-ray of each subject. Chronic productive cough topped the list of respiratory symptoms (89%) followed by chest pain (74%) and dyspnea (62%). Lung consolidation was the commonest respiratory sign as seen in 44% of the cases. Hilar lymphadenopathy was seen in (35%), Pleural effusion (32%), lung fibrosis (21%) and finger clubbing (15%). The clinical and radiological pattern of most patients with chronic cough washighly suggestive of mycobacterial infection such as tuberculosis, although only 40% of cases had positive Acid Fast Baccilli. The mean CD4 lymphocyte count level was 174.8 + 5.4 cells/l and thismay be responsible for the respiratory findings as opportunistic lung infections are said to be commoner at CD4 count levels below 200 cells/l. However, four patients had mediasternal masseswhich may suggest neoplasms. Concerted efforts and continuous evaluation of these patients are needed to determine the spectrum of respiratory illnesses among HIV positive patients in Calabar

Transgressive learning in times of global systemic dysfunction: interview with Arjen Wals

Arjen Wals is Professor of Transformative Learning for Socio-Ecological Sustainability at Wageningen University. He also holds the UNESCO Chair of Social Learning and Sustainable Development. Furthermore he is the Carl Bennet Guest Professor in Education for Sustainable Development (ESD) at Gothenburg University in Sweden. He obtained his PhD in 1991 with a Fulbright fellowship at the University of Michigan in Ann Arbor. His dissertation tackled the interface of environmental psychology and environmental and sustainability education. His recent work focuses on transformative social learning in vital coalitions of multiple stakeholders at the interface of science and society. His teaching and research focus on designing learning processes and learning spaces that enable people to contribute meaningfully sustainability. A central question in his work is: how to create conditions that support (new) forms of learning which take full advantage of the diversity, creativity and resourcefulness that is all around us, but so far remain largely untapped in our search for a world that is more sustainable than the one currently in prospect? In 2014 he was the lead author of an article published in Science Magazine on the role of citizen science in bridging science education, environmental education and sustainability. He is editor and co-editor of a number of popular books including: Higher Education and the Challenge of Sustainability (Kluwer Academic, 2004), Creating Sustainable Environments in our Schools (Trentham, 2006), Social Learning towards a Sustainable World with foreword by Fritjof Capra and an afterword by Michael Apple (Wageningen Academic, 2007), Learning for Sustainability in Times of Accelerating Change (2012), and of Routledge’s International Handbook on Environmental Education Research (2013). He has (co)authored over 250 publications in multiple languages. Wals is a co-founder of Caretakers of the Environment/International and a recipient of the environmental education research award of the North American Association for Environmental Education, and former president of the Special Interest Group on Environmental & Ecological Education of the AERA. He writes a regular research blog that signals developments in the emerging field of sustainability education: www.transformativelearning.n

Puroindolines polymorphism and kernel texture in einkorn (Triticum monococcum)

BACKGROUND: Patients with severe asthma experience problems in different areas of their health status. Identification of these areas will provide insight in the patients needs and perhaps what determines the burden of disease. The Nijmegen Clinical Screening Instrument (NCSI) was recently developed for use in clinical practice in patients with COPD and provides a detailed picture of the patients' physiological functioning, symptoms, functional impairment, and Quality of Life. Main purpose of this study is to evaluate the use of the NCSI as compared to the Asthma Control Questionnaire (ACQ) and Asthma Quality of Life Questionnaire (AQLQ) in patients with severe asthma. METHODS: The NCSI, AQLQ, and ACQ were measured in 167 patients with severe asthma. Pearson correlations were calculated between NCSI sub-domains and the AQLQ domains and the ACQ. RESULTS: The NCSI measures more aspects of health status as compared to the ACQ and AQLQ in patients with severe asthma. Beside symptoms, subjective impairment, and emotions the NCSI also measures general Quality of Life, health related Quality of Life, satisfaction with relations, fatigue, and behavioural impairment. On all NCSI sub-domains proportions of patients with normal, mild, and severe problems were found. Heterogeneity was found on the number and on the combination of sub-domains on which patients reported severe problems. CONCLUSIONS: The NCSI provides a more detailed picture of the individual patient with severe asthma than the ACQ and AQLQ. The use of the NCSI might allow quick identification of the problem areas and possible factors that impair health status

The Diabetes Remission Clinical Trial (DiRECT): protocol for a cluster randomised trial

Background: Despite improving evidence-based practice following clinical guidelines to optimise drug therapy, Type 2 diabetes (T2DM) still exerts a devastating toll from vascular complications and premature death. Biochemical remission of T2DM has been demonstrated with weight loss around 15kg following bariatric surgery and in several small studies of non-surgical energy-restriction treatments. The non-surgical Counterweight-Plus programme, running in Primary Care where obesity and T2DM are routinely managed, produces >15 kg weight loss in 33 % of all enrolled patients. The Diabetes UK-funded Counterpoint study suggested that this should be sufficient to reverse T2DM by removing ectopic fat in liver and pancreas, restoring first-phase insulin secretion. The Diabetes Remission Clinical Trial (DiRECT) was designed to determine whether a structured, intensive, weight management programme, delivered in a routine Primary Care setting, is a viable treatment for achieving durable normoglycaemia. Other aims are to understand the mechanistic basis of remission and to identify psychological predictors of response. Methods/Design: Cluster-randomised design with GP practice as the unit of randomisation: 280 participants from around 30 practices in Scotland and England will be allocated either to continue usual guideline-based care or to add the Counterweight-Plus weight management programme, which includes primary care nurse or dietitian delivery of 12-20weeks low calorie diet replacement, food reintroduction, and long-term weight loss maintenance. Main inclusion criteria: men and women aged 20-65years, all ethnicities, T2DM 0-6years duration, BMI 27-45 kg/m2. Tyneside participants will undergo Magnetic Resonance (MR) studies of pancreatic and hepatic fat, and metabolic studies to determine mechanisms underlying T2DM remission. Co-primary endpoints: weight reduction ≥ 15 kg and HbA1c <48 mmol/mol at one year. Further follow-up at 2 years. Discussion: This study will establish whether a structured weight management programme, delivered in Primary Care by practice nurses or dietitians, is a viable treatment to achieve T2DM remission. Results, available from 2018 onwards, will inform future service strategy
