Context: Deficient HRH management – especially insufficient training and motivation, and adverse distribution of qualified staff countrywide, at the expense of poor and remote areas – has been identified for over a decade as one major constraint for the implementation of Mali's national health policy. Main objective: The HRH policy aims to define a coherent framework for the ministry of health (MoH) and its partners in order to ensure the harmonious development, distribution, management and motivation of health staff so as to ultimately improve health results. The policy is translated into an operational plan dealing specifically with training, recruitment, motivation, and career management. Methodology: The HRH policy and plan were developed by a core team under the leadership of the Planning Department of the MoH, with the involvement from other departments of the MoH, the ministries in charge of finance (MoF) and civil service (MoCS), and donors. After analyzing existing studies and data, the diagnosis over the major problems to be tackled was done. This allowed identifying the main orientations of the policy, which were then translated into strategies and interventions, and then costed. Once the policy and plan have been drafted by the core team, they have been circulated to all departments and partners and discussed in several meetings with different stakeholders at central level. After integrating comments from these meetings, the MoH organized a validation workshop with very broad participation (including the operational level, private sector, and civil society) so as to ensure ownership. Final amendments were negotiated with the MoF and MoCS in order to be adopted as a national policy by the Counsel of Ministers by the end of 2009. Results: The HRH policy and plan now benefit from wide political support by major stakeholders. Yet, implementation still has been delayed because of the management modalities at operational level still need to be definitively agreed upon. Conclusion: The inclusive development process has been necessary to move on with the complex and highly sensitive issue of HRH management, and to get the support from MoF, MoSC and donors who are supposed to contribute to its financing.

Data and information required by hydrogeological studies are various and complex such as geology, topography, climate, hydrological and hydrogeological raw or pre-processed data. All these data need to be managed, and this can be done in a structured database. A (GIS-managed) hydrogeological database has been developed previously by the Hydrogeology Group of the University of Liège (Gogu et al., 2001) in order to capture, store, edit, query, update and display geographically referenced hydrogeological data. The development of this geo-relational database was constrained by a maximum storage of data with a minimum data redundancy, reduction of storage memory capacity and optimum ‘retrievability’ of information for further analysis. In recent years, the use of Geographical Information System (GIS) has grown rapidly in groundwater management and research. GIS is now widely used to create digital geographic databases, to manipulate and prepare data as input for various model parameters, and to display model output. Coupling GIS with this hydrogeological database provides a powerful tool. This GIS-managed hydrogeological database has been also developed for vulnerability-assessment techniques and numerical modelling for groundwater flow and contaminant transport studies. As well as linking between database and GIS, the design of coupling database with process-based numerical models was also performed. This methodology has been applied, in a semi-arid region: the "Oulmès plateau" located in the Mid-Atlas (Morocco). This study has led to a detailed hydrogeological map at the scale of 1/25000. First, data were collected from existing databases, studies and maps as well as through new field measurements. These data came from numerous and various sources and in different formats (paper or digital diagrams, images, spreadsheets…). After validation, it has been encoded in the hydrogeological database. Because data are geo-referenced, it can be easily represented on the map within GIS-software. The hydrogeological map displays several layers of information as topography, hydrogeological units, hydrographic network, wells, piezometers, isoline of piezometric heads. [less ▲]

This article presents the assumptions and the issues that arise when developing an integrated modelling methodology between a Computational Fluid Dynamics (CFD) software applied to compartment fires and a finite element (FE) software applied to structural systems. In particular, a weak coupling methodology use to simulate a fire exposed structure by modelling the fire development in the compartment, the heat penetration in the structure and the mechanical response is described. The advantages and the disadvantages of such a technique are highlighted compared to a full coupling that conversely takes into account all mutual interactions. This methodology is particularly suitable for relatively thin steel structures in large compartments. Moreover, the need of a standardised transfer file in order to get the methodology as flexible as possible in term of versatility is emphasized. [less ▲]

A microbioassay was developed for evaluating the in vitro antifungal activity of 30 preselected essential oils. A template based on 10 serial dilutions with eight replicates per dilution arranged on two 96-well ELISA plates was used as a reproducible and standardized design to identify the in vitro effectiveness of these essential oils against Penicillium italicum Wehmer, Penicillium digitatum Sacc. and Colletotrichum musea (Berk. M.A. Curtis) Arx, three postharvest fungal pathogens, on fruits. Growth of mycelium was monitored by measuring optical density (492 nm). Cinnamomum zeylanicum, Cinnamomum verum and Eugenia caryophyllus were found to be still active against all the three pathogens even at 100 ppm. Compared to other methods, this microbioassay proved to be a rapid, reproducible, and efficient method for testing the efficacy of essential oils that inhibit spore germination in P. italicum, P. digitatum and C. musea. The assay requires relatively small amounts of essential oils. [less ▲]

In 2011, the European Union prohibited the production of polycarbonate (PC) baby bottles due to the toxic effects of the PC monomer bisphenol-A. Therefore, baby bottles made of alternative materials, e.g. polypropylene (PP) or polyethersulphone (PES), are currently marketed. The principal aim of the study was the identification of major compounds migrating from baby bottles using a liquid–liquid extraction followed by GC/MS analysis. A 50% EtOH in water solution was selected as a simulant for milk. After sterilisation of the bottle, three migration experiments were performed during 2 h at 70°C. A nontargeted liquid–liquid extraction with ethyl acetate–n-hexane (1:1) was performed on the simulant samples. Identification of migrants from 24 baby bottles was done using commercially available WILEY and NIST mass spectra libraries. Differences in the migrating compounds and their intensities were observed between the different types of plastics, but also between the same polymer from a different producer. Differences in the migration patterns were perceived as well between the sterilisation and the migrations and within the different migrations. Silicone, Tritan™ and PP exhibited a wide variety of migrating compounds, whereas PES and polyamide (PA) showed a lower amount of migrants, though sometimes in relatively large concentrations (azacyclotridecan-2-one up to 250 µg kg−1 ). Alkanes (especially in PP bottles), phthalates (dibutylphthalate in one PP bottle (±40 µg kg−1 ) and one silicone bottle (±25 µg kg−1 ); diisobutylphthalate in one PP (±10 µg kg−1 ), silicone (up to ±80 µg kg−1 ); and Tritan™ bottle (±30 µg kg−1 )), antioxidants (Irgafos 168, degradation products of Irganox 1010 and Irganox 1076), etc. were detected for PP, silicone and Tritan™ bottles. Although the concentrations were relatively low, some compounds not authorised by European Union Regulation No. 10/2011, such as 2,4-di-tert-butylphenol (10–100 µg kg−1 ) or 2-butoxyethyl acetate (about 300 µg kg−1 ) were detected. Migrating chemicals were identified as confirmed (using a standard) or as tentative (further confirmation required). [less ▲]

We describe the potential for high-resolution detection, observation and chemical analysis of tephras and cryptotephras in freeze-dried and resin-impregnated peat sections. Special attention is drawn to tephra grain alteration products, sensitive to standard lab treatment, but preserved using an impregnation technique developed here. Resulting blocks and thin sections provide a continuous archive of tephras that can be investigated through a wide range of non-destructive techniques encompassing polarising and fluorescence microscopy, scanning electron microscopy with/without elemental analysis, and XRF-based core scanning.

Measurement of mRNA expression by real-time RT-PCR (QRT-PCR) has proven to be an important and powerful tool for the investigation of the pathogenesis of inflammatory and immune-mediated diseases in many species. This methodology has proven particularly valuable in the dog, a species for which there are currently few specific antibodies for measurement of relevant proteins. Internal control (housekeeper) mRNAs are widely used for normalisation of QRT-PCR results. The validation and use of multiple internal control mRNAs for increased accuracy of normalisation has been described for humans and rodents. The aims of this study were to develop QRT-PCR assays for 11 potential internal control mRNAs in the dog (ACTB, B2M, G3PDH, HMBS, HPRT1, RPL 13A, RPL32, RPS 18, SDHA, TBP and YWAZ) and validate their use with bone marrow, colon, duodenum, heart, kidney, liver, lung, lymph node, skeletal muscle, pancreas, spleen and stomach from seven dogs. Endoscopic biopsies of the superficial duodenal mucosa were also obtained from nine dogs suffering from chronic gastro-oesophageal disease. The most stably expressed genes varied in the tissues examined. RPL13A and RPL32 (both components of the 60S ribosomal subunit) were the most stably expressed genes in the majority of the tissues examined, whereas ACTB and B2M were the least stable. Distinct internal control genes were shown to be most appropriate for use in full-thickness versus superficial mucosal biopsies of the duodenum. The results of this study indicate that there are no universal control genes for gene expression studies in canine tissues. It is important to use multiple internal control genes based upon a survey of potential control genes applied to representative samples from different disease groups, culture conditions and/or time points in an experimental study.

The main objective of this paper is to establish a set of test cases for analytical verifications and intermodel comparisons of ground heat exchanger (GHX) models used in building simulation programs. Several test cases are suggested. They range from steady-state heat rejection in a single borehole to varying hourly loads with large yearly thermal imbalance in multiple borehole configurations. The usefulness of the proposed test cases is illustrated by running them with different GHX models. This comparison exercise has shown that 1-D models compare favourably well with the more elaborate 3-D models for relatively small simulation periods. The cyclic heat rejection/collection test has revealed some small deficiency in the load aggregation scheme of a particular model. Finally, the use of the asymmetric (cooling dominated) load profile test case for a bore field composed of 100 boreholes revealed that the borehole wall temperature predicted by two GHX models can differ by as much as 10oC after a 30 year simulation.

A simple questionnaire would be useful to identify individuals most in need of bone mineral density (BMD) testing. We designed a new predictive model and risk assessment instrument based on an extensive review of the literature evaluating risk factors for osteoporosis, and tested its performance in a large cohort of postmenopausal women in whom BMD was measured by dual x-ray absorptiometry. In total, 1303 postmenopausal women from an outpatient osteoporosis clinic participated in this study. The Osteoporosis Index of Risk (OSIRIS) is based on four variables: age, body weight, current hormone replacement therapy use and history of previous low impact fracture. The sensitivity and specificity for an OSIRIS value of +1 were respectively 78.5% and 51.4%. The AUC under the ROC curve of OSIRIS was 0.71. Three categories were arbitrarily created using OSIRIS, with cutoff of +1 and -3. The low risk category (OSIRIS > +1) represented 41% of all women; only 7% of the women in this category had osteoporosis. The prevalence of osteoporosis was very high (66%) among the group at high risk (OSIRIS < -3 representing 15% of all women). The prevalence of osteoporosis was 39% in the intermediate risk group (-3 < OSIRIS < +1, 44% of all women). In conclusion, OSIRIS is a simple index based on four easy-to-collect variables from postmenopausal women, it shows a high degree of accuracy, and performed well for classifying the degree of risk of osteoporosis in western European women of Caucasian lineage. Based on this instrument it is possible to propose a strategy that would initiate treatment in women with very high risk, postpone BMD measurement in women with low risk and limit BMD measurement to women with intermediate risk of osteoporosis, this would spare more than 55% of the densitometry bill compared with a mass screening scenario.
