We show that a remarkable compatibility exists between the results of a potential model with constituent quarks and the 1/Nc expansion mass formula for strange and nonstrange baryon resonances. Such compatibility brings support to the basic assumptions of relativistic quark models and sheds light on the physical content of the model-independent large Nc mass formula. Good agreement between both approaches is also found for heavy baryons, made of one heavy and two light quarks, in the ground state band. [less ▲]

For many years, the Strasbourg Manuscript was believed to be the oldest German-language source for the study of Northern European painting techniques. Unfortunately, the manuscript was lost in the 1870 fire at the Strasbourg Library, and the text only survives in a 19th-century transcription made for Eastlake (1847). Studies such as those of Ploss and more recently those of Oltrogge have already highlighted the existence of texts with very similar contents, grouping them under the name of the ‘Strasbourg family’. Since these studies, a clearly defined corpus of manuscripts has been established as belonging to this family. This paper shows the different degrees of connection between the texts and presents some suggestions concerning their compilation process. The possibility of collating different versions of an identical text and cross-checking recipes can also be exploited to learn more about the ways in which recipe books were compiled, and to provide information concerning their use and function.

A systematic experimental study has been carried out to compare the residual energy at the toe of a stepped spillway of varied length considering a classical ogee-crested weir (OCW) or two different piano key weirs (PKW) at the top of the structure. Four spillway lengths have been considered on a wide range of discharge. An indirect method has been used to compute the residual flow energy at the spillway toe from water depth measurements in a horizontal channel downstream. The results indicate that uniform flow conditions, i.e. flow energy at the spillway toe independent of the spillway length, are reached on significantly shorter spillways downstream of a PKW than downstream of an OCW. However, the uniform flow energy at constant discharge on the spillway is found to vary depending on the weir type. In particular, it is smaller downstream of the OCW than downstream of the PKWs.

n this paper, we compare the viscosimetric and tribological properties of some vegetable oils and one synthetic ester with a pure mineral oil. The viscosimetric characteristics of lubricants show that both vegetable oils and ester have a higher viscosity index than mineral oil. The test results show that all tested oils have a somewhat dilatant behaviour.The oiliness, antiwear and extreme pressure properties of lubricants have been studied respectively with a Stribeck machine and a four-ball machine. We have noted the following: On the four-ball machine, extreme pressure results expressed in terms of pressure wear index and mean hertz load show that the higher performance is obtained with the vegetable oils. Extreme pressure results expressed in terms of weld load, do not show a big difference between the tested oils. Antiwear results expressed in terms of wear scar show that die highest performances are obtained with vegetable oils. On the Stribeck machine, oiliness results expressed in terms of friction coefficient indicate that: in the regime of fluid lubrication, tested oils have me same behaviour; in die boundary lubrication regime, both vegetable oils and synthetic, ester have a better response uian mineral oil.

The paper covers a brief description and a comprehensive comparative analysis of several state-of-the-art dam breaching models. The study is specifically focused on the applicability and on the predictive capacity of the models for the gradual breaching of an overtopped rockfill dam. A wide range of modelling techniques is reviewed, from process-oriented numerical simulations to empirical models. Comparisons are performed regarding various aspects, such as the applicability of the model without prior calibration or the possibility of coupling the breaching model with a quasi-3D flow solver such as WOLF. Finally, a sensitivity analysis of the downstream hydrograph to various parameters is conducted and the conclusions drawn are illustrated in the case of a large-scale real application in Belgium.

Palm oil is without doubt the most widely fractionated oil. Dry fractionation is based on differences in the melting points of triacylglycerols (TAG) which will crystallize selectively during the cooling process. Unfortunately, limitations due to intersolubility, closely linked to polymorphism, induce formation of co-crystals at each crystallization step. For this reason, only restricted TAG enrichments are observed. In this work, a series of samples (24) of palm oil, solid and liquid fractions (stearins, mid fractions, oleins and superoleins) have been selected and examined in terms of TAG composition (by HPLC), differential scanning calorimetry (DSC) melting profile and variable temperature powder X-ray diffraction pattern. Three major endotherms [low-melting, high-melting and very high-melting peaks (LMP, HMP and VHMP)] are detected in the DSC melting profiles (5 degrees C/min). The VHMP is only recorded for palm stearin which contains more SSS components. The HMP contribution is weak for palm olein and even not observed for palm super oleins. The LMP is usually made up of UUU, SUU and SUS components; SUS components are observed in both LMP and HMP; the HMP is also made up of some SSS, except for palm oleins and super oleins. Sub-alpha(2), sub-alpha(1), alpha, beta'(2), beta'(1), and beta polymorphic forms are recorded; the LMP components preferentially crystallize in sub-alpha(2), sub-alpha, and alpha forms; the HMP components generally crystallize in beta'(2) and beta'(1), with a tendency to exhibit beta crystals, depending on the SSS content. Components of the VHMP have an increased tendency to stabilize in the 0 form; in view of the results, we can assume that there is a clear relationship between TAG composition, melting properties and polymorphic behavior and of palm oil and fractions.

Introduction: The International Health Partnership and related initiatives (IHP+) seeks to achieve better results by mobilising development partners around a single country-led national health strategy, guided by the principles of the Paris Declaration on Aid Effectiveness. At country level, the IHP+ materializes through the preparation, signature, implementation, and monitoring and evaluation of a "Country Compact" – a negotiated and signed agreement in which partners commit to implement and uphold the priorities outlined in the national health strategy. Some of the main determining features of the IHP+ are the leadership of the recipient government over the preparation and implementation process of the Compact, broad domestic ownership of the national health plan, and mutual accountability for results. Methods: In this communication, we perform a comparative analysis of two very different approaches that have been followed in Mali and Benin. It is based on authors' experience in the IHP+ process in Mali, extensive document review and interviews with most significant stakeholders involved in the process both in Mali and Benin. Results: Mali has prepared its country Compact on the grounds of its 10-year experience in leading a sector-wide approach (SWAp) in the health sector. It has therefore benefited from improved donor coordination, MoH leadership in piloting the national programme, trust capital between partners and broad ownership of the health plan. It has succeeded in making the IHP+ process even more inclusive. On the contrary, Benin had no health SWAp to start with. The preparation process of the Compact was much less inclusive and country-led, resulting in narrow ownership and vague commitments. Nevertheless, it is hoped that the IHP+ can help launch a new partnership dynamic within the health sector. Conclusion: Beyond common principles, the IHP+ is put into practice in different ways from country to country according to their context. [less ▲]

The purpose of this study was to compare the antioxidant capacities of standard compounds (phenolic compounds, ascorbic acid, and glutathione) as measured by various assays. Five methods were selected so as to span a diversity of technical approaches: TEAC (radical 2,2′-azino-bis(3-ethylbenzothiazoline)-6 sulphonic acid), DPPH (radical 2,2-diphenyl-1-picryhydrazyl used to measure reducing capacity), ORAC (oxygen radical scavenging capacity), red blood cell haemolysis (protection of biological sample), and ESR (electron spin resonance for direct free radical evaluation). Most compounds showed significant differences in free radical scavenging activity according to the method used. Of the 25 tested compounds, only a few, such as myricetin and gallocatechin, gave comparable activities in the various tests. To standardise reporting on antioxidant capacity, it is proposed to use a weighted mean of the values obtained using the DPPH, ORAC, resistance to haemolysis, and ESR assays. This strategy was used to test the antioxidant capacity of several beverages. The highest antioxidant capacity was observed for red wine, followed by green tea, orange juice, grape juice, vegetable juice, and apple juice. [less ▲]
