Published: June 2013

Abstract
The partition coefficients of platinum group elements (PGE) and chalcophile elements Au, Re, Ag, Se, Bi, Te, and Sb, between arsenide and sulfide phases (DAs/sulf) have been estimated by measuring in situ concentrations of these elements using laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) in coexisting arsenide and sulfide minerals from the Beni Bousera Cr-Ni mineralization (North Morocco). Previous experimental studies and observations on the distribution of PGE in a number of As-rich, Ni-Cu-PGE ore deposits have shown that arsenide minerals may play an important role controlling the distribution of these metals in magmatic sulfide systems. However to date, there is no comprehensive study quantifying the partitioning behavior of these elements when arsenide minerals crystallize either directly from a sulfide melt or from an arsenide melt previously segregated by immiscibility from a sulfide melt. The Beni Bousera mineralization represents an excellent natural laboratory to evaluate these partition coefficients because maucherite (Ni11As8) coexists in equilibrium with pyrrhotite, pentlandite, and chalcopyrite in form of globules mostly associated with pyrrhotite, and arsenide and sulfide minerals account for the bulk of the PGE (with the exception of Pt) and chalcophile elements in the samples. The laser ablation analyses reveal that maucherite is strongly enriched in all chalcophile elements, except Se, relative to sulfide minerals. The calculated DPGEAs/sulf are the following: DIrAs/sulf = 920 DRhAs/sulf = 620, DPtAs/sulf = 330, DPdAs/sulf = 250, DOsAs/sulf = 140, and DRuAs/sulf = 50. For the rest of elements, the obtained values are the following: DSbAs/sulf = 890, DTeAs/sulf = 190, DBiAs/sulf = 50, DReAs/sulf = 6, DAuAs/sulf = 310, DAgAs/sulf = 4, and DSeAs/sulf = 0.6. These results clearly highlight the strong affinity of PGE for arsenide phases and the importance of these phases as potential carriers of PGE in Ni-Cu-PGE ore deposits.

ABSTRACTEvaluation of creeping bentgrass (Agrostis stolonifera L.) salt tolerance often showed inconsistent results. The objective of this study was to investigate the reactions of ‘Seaside II’ and ‘T‐1’ to NaCl, Na2CO3, Na2SO4, and CaCl2, each at concentrations of 0, 25, 75, 125, 175, and 225 mM. Chlorophyll a (Chla) content was the lowest in the CaCl2 treatment followed by Na2CO3 and Na2SO4 and highest in NaCl whereas chlorophyll b (Chlb) content was lowest in Na2CO3 followed by CaCl2 and Na2SO4 and highest in NaCl. Turfgrass visual quality and green density were reduced the most by the Na2CO3 and CaCl2 treatments. Evapotranspiration (ET) decreased in the order of treatments CaCl2, Na2SO4, Na2CO3, and NaCl at 1 wk after treatment (WAT), but at 4 WAT there were no difference among CaCl2, Na2SO4, and Na2CO3. Significant salt type × concentration interaction existed, and the first order or second order coefficient of regression equation ranked the changing rate of physiological parameters differently in different salts. Leaf K+:Na+ ratio was affected differently by salts and a threshold of 1 appeared at different salt concentrations depending on salt types and cultivars. The pH, osmotic potential, and electrical conductivity of salt solutions were confounded making the interpretation of mechanisms of physiological stress difficult. Nevertheless, this study showed that different salts rank creeping bentgrass salt tolerance differently.

ABSTRACTThis study compared the animal performance of beef calves stocked on bahiagrass (Paspalum notatum Flüggé) basal pastures (1.2 ha) without supplementation (Control) or with supplementation in the form of creep‐grazed (0.12 ha) perennial peanut (Arachis glabrata Benth.) or cowpea [Vigna unguiculata (L.) Walp.] or a creep‐fed concentrate. Twenty‐four cow–calf pairs were assigned to two blocks. Cows weighed 559 ± 98 kg, averaged 5.5 ± 0.6 body condition score, and were 5 ± 3 yr old, and calves weighed 152 ± 32 kg and were 139 ± 27 d old. The first block had duplicate pastures for the control, cowpea creep grazing, and creep feed treatments whereas the second block had duplicate pastures for cowpea, perennial peanut, and the control treatments. Herbage mass of cowpea was greater than that of perennial peanut or bahiagrass in Weeks 2 to 4 in Year 1 and Week 4 in Year 2 and then declined. The neutral detergent fiber (NDF) concentrations of cowpea and perennial peanut were less than that of bahiagrass, and crude protein and in vitro true digestibility of cowpea were consistently greater than that of perennial peanut and bahiagrass. In Year 1, weaned calf body weights of creep‐grazed or creep‐fed calves were greater than that of the control calves and creep grazing cowpea or creep feed resulted in similar increases in Year 2. Calf average daily gain (ADG) was greatest for creep feed but did not differ among other treatments. Calf performance was improved by creep feeding concentrate followed by creep grazing cowpea. Benefits of cowpea on ADG were constrained by reduction in cowpea herbage mass and nutritive value during the grazing period.
Diallel Analysis Models: A Comparison of Certain Genetic Statistics

Published: June 2013

ABSTRACTDiallel analyses, although popular, raise key questions: (i) Do genetic statistics from different diallel methods with same and different sets of lines offer the same or similar information? and (ii) Would lack of information on reciprocal (REC) and maternal (MAT) effects in certain diallels put breeding programs at risk? To answer these questions, general (GCA) and specific combining ability (SCA), MAT, and REC effects were calculated from diallels with 12, 10, 8, 6, and 4 maize (Zea mays L.) parents. We found that with the same lines, the signs and magnitudes of GCA effects were similar and highly correlated among Griffing's Methods 1, 2, 3, and 4 and identical between Griffing's Method 4 and Gardner and Eberhart analysis III (G&EIII). The SCA effects from Griffing's Methods 1 to 4 were correlated. Griffing's Method 4 produced SCA effects identical to G&EII and G&EIII; SCA effects from Griffing's Methods 1 and 2 were upwardly biased because of inclusion of parental lines. Griffing's Method 3 (no parents included) was the best method among all six methods; it gave unbiased SCA estimates and information on MAT and REC effects. With different numbers of lines in diallel crosses, genetic statistics could serve as references across breeding programs because the signs of GCA and SCA effects were mostly same; however, caution must be exercised because some effects with opposite signs were detected. A diallel method that does not provide REC and MAT information could miss identifying superior hybrid(s). Because Methods 1 and 2 provided upwardly biased estimates of GCA and SCA effects, they are not recommended for estimation of GCA and SCA effects. We also concluded that Method 3 was the best diallel method; it provided unbiased estimates of SCA effects and also provided crucial REC and MAT effects, which are useful for proper selection of male and female parents in hybrid development.
The Comparing of Ultrasound-guided Techniques: Sciatic Block with
Continuous Lumbar Plexus Block or Continuous Femoral Nerve Block for
Anesthesia and Analgesia of Total knee Replacement
Authors: Dauri M. , Faria S. , Celidonio L. , David P. , Bianco A. , Fabbi E. , Silvi M.B. 
Published: June 2013

Background and Aims:
This double blind prospective randomized clinical trial evaluated the efficacy and safety
of continuous ultrasound-guided lumbar plexus block compared to continuous ultrasound-guided femoral nerve block, in
the intra-operative and postoperative periods after total knee replacement.

Methods:
Forty ASA I-III patients were randomized to receive: continuous femoral block (n= 20, 30 ml of ropivacaine 5
mg/ml) or continuous lumbar plexus block (n= 20, 30 ml of ropivacaine 5 mg/ml) both in association with single injection
sciatic nerve block. All patients received continuous infusion of 2 mg/ml of ropivacaine at 8 ml/h for 48 hours and intravenous
morphine for patient-controlled analgesia. Primary outcomes were intra-operative sufentanil consumption and
verbal analogue scale (VAS) score at rest at 24h follow up.

Results:
Intra-operative sufentanil consumption was higher in the femoral block (FEM) group compared to the lumbar
plexus block (PSOAS) group (FEM: 10.00 (10.00, 17.50) µg; PSOAS: 2.50 (0.00, 10.00) µg. p= 0.002).
Obturator motor blockade occurred more frequently in the PSOAS group (70%) than in the FEM group (40%) (p=0.1);
however, we found no differences in sensory blockade (p=0.6).
VAS at rest was similar in the two groups at 24h postoperatively (FEM: 29.50 ± 14.74 mm; PSOAS: 25.60 ±17.42 mm.
p=0.4), and throughout the follow-up period. No differences were detected in pain scores during physiotherapy.

Conclusion:
Continuous femoral and lumbar plexus blocks, both in association with sciatic nerve block, provided similar
VAS scores at 24h, and throughout the follow-up period; intra-operative sufentanil consumption was, however, lower in
the lumbar plexus block group.
Bridging the Gap between Tertiary Education and Work: Situated Learning in Accountancy
Authors: Stanley Trevor 
Published: June 2013

ABSTRACT
In professions such as teaching, health sciences (medicine, nursing), and built environment, significant work-based learning through practica is an essential element before graduation. However, there is no such requirement in professional accounting education. This paper reports the findings of an exploratory qualitative case study of the implementation of a Workplace Learning Experience Program in Accountancy at the Queensland University of Technology (QUT) in Australia. The interview-based study documents the responses of university students and graduates to this program. The study demonstrates that a 100-hour work placement in Accountancy can enhance student learning. It highlights the potential value of the application of sociocultural theories of learning, especially the concept of situated learning involving legitimate peripheral participation (Lave and Wenger 1991). This research adds to a small body of empirical accounting education literature relating to the benefits of work placements prior to graduation. The effectiveness of this short, for credit, unpaid program should encourage other universities to implement a similar work placement program as a form of pre-graduation learning in professional accounting education.

OBJECTIVE
We aimed to evaluate the added value of intensive self-monitoring of blood glucose (SMBG), structured in timing and frequency, in noninsulin-treated patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS
The 12-month, randomized, clinical trial enrolled 1,024 patients with noninsulin-treated type 2 diabetes (median baseline HbA1c, 7.3% [IQR, 6.9–7.8%]) at 39 diabetes clinics in Italy. After standardized education, 501 patients were randomized to intensive structured monitoring (ISM) with 4-point glycemic profiles (fasting, preprandial, 2-h postprandial, and postabsorptive measurements) performed 3 days/week; 523 patients were randomized to active control (AC) with 4-point glycemic profiles performed at baseline and at 6 and 12 months. Two primary end points were tested in hierarchical order: HbA1c change at 12 months and percentage of patients at risk target for low and high blood glucose index.

RESULTS
Intent-to-treat analysis showed greater HbA1c reductions over 12 months in ISM (−0.39%) than in AC patients (−0.27%), with a between-group difference of −0.12% (95% CI, −0.210 to −0.024; P = 0.013). In the per-protocol analysis, the between-group difference was −0.21% (−0.331 to −0.089; P = 0.0007). More ISM than AC patients achieved clinically meaningful reductions in HbA1c (&gt;0.3, &gt;0.4, or &gt;0.5%) at study end (P &lt; 0.025). The proportion of patients reaching/maintaining the risk target at month 12 was similar in ISM (74.6%) and AC (70.1%) patients (P = 0.131). At visits 2, 3, and 4, diabetes medications were changed more often in ISM than in AC patients (P &lt; 0.001).

CONCLUSIONS
Use of structured SMBG improves glycemic control and provides guidance in prescribing diabetes medications in patients with relatively well-controlled noninsulin-treated type 2 diabetes.
Assessment of Gamma Dose Rate at Mine Waste Dump

Published: June 2013

Abstract
Exploitation of coal deposits in Upper Silesia is associated with production of large quantities of waste deposited at dumps. The tested samples from five dumps showed different radioactivity from each other. Radioactivity measurements made it possible to analyze the degree of risk with the factors specified by UNSCEAR such as radium equivalent activity Raeq, internal Ein and external Eex occupancy factor. There is a raised level of radiation in dumps as compared with outside dump areas. In the study area, however, there is no risk associated with elevated levels of radiation in relation to standards established by the Council of Ministers of the ionizing radiation dose limits.
Comparison of daily potential evapotranspiration calculated by two procedures based on Penman-Monteith type equation
Authors: Hlaváčiková Hana , Novák Viliam 
Published: June 2013

Abstract
Paper presents comparison of the daily reference crop (grass vegetation cover) potential evapotranspiration results calculated by the two modifications of the Penman-Monteith type equation. The first modification was published in FAO recommendation (Allen at al., 1998), PM-FAO, the second is modification according to Budagovskiy (1964) and Novák (1995), PM-BN. Both are used in soil water simulation models HYDRUS-1D and GLOBAL. Calculations were performed for frost-free seasons of the years 2000-2009, using the meteorological station Gabčíkovo (South Slovakia) meteorological data and canopy characteristics. The results indicate significant differences in daily and seasonal potential evapotranspiration. Reasons for those differences are discussed; they should be in different net radiation and aerodynamic resistance estimation methods.
On a class of finite solvable groups
Authors: Beidleman James , Heineken Hermann , Schmidt Jack 
Published: June 2013

Abstract
A finite solvable group G is called an X-group if the subnormal subgroups of G permute with all the system normalizers of G. It is our purpose here to determine some of the properties of X-groups. Subgroups and quotient groups of X-groups are X-groups. Let M and N be normal subgroups of a group G of relatively prime order. If G/M and G/N are X-groups, then G is also an X-group. Let the nilpotent residual L of G be abelian. Then G is an X-group if and only if G acts by conjugation on L as a group of power automorphisms.
Production of Synseed for Hybrid Cymbidium Using Protocorm-Like Bodies
Authors: Teixeira da Silva Jaime A. 
Published: June 2013

Abstract
Synthetic seed were produced from protocorm-like bodies (PLBs) of hybrid Cymbidium Twilight Moon ‘Day Light’ after culture on a new medium, Teixeira Cymbidium (TC) medium. This new medium contained, in addition to a unique selection of macro- and micronutrients, 0.1 mg/l α-naphthaleneacetic acid and 0.1 mg/l kinetin, 2 g/l tryptone and 20 g/l sucrose, and was solidified with 8 g/l Bacto agar. Several explant types and sizes (intact PLBs, half-PLBs, PLB longitudinal thin cell layers) were tested. In addition, pretreatment of PLB-synseeds with 200 mM KNO3 solution, the addition of activated charcoal or coconut water to synseeds, light vs dark culture, short-term (1 month) and long-term (6 and 12 months) low-temperature (4°C) storage, as well as cryostorage were also tested. All treatments resulted in less PLBs than the control treatment. Among all these treatments, only the use of TC medium or incorporation of coconut water into synseeds resulted in “germination” while lowtemperature storage (1-6 months) was only possible under liquid TC. These results would allow for the short-term preservation of Cymbidium germplasm but not for effective cryopreservation.
Morphactin Substantially Induced the Fourth Internode Growth in Decapitated Tulips: Relevance to Endogenous Levels of Indole-3-Acetic Acid

Published: June 2013

Abstract
Important role of auxin polar transport inhibitors such as TIBA (2,3,5- triiodobenzoic acid), NPA (N-(1-naphthyl)phthalamic acid) and morphactin (methyl 2-chloro-9-hydroxyfluorene-9-carboxylate) in stem growth of tulips was intensively studied. After the application of morphactin above the 3rd node of decapitated tulips, the stimulated growth of the 4th internode was clearly observed. On the other hand, NPA and TIBA were slightly effective in stimulating the 4th internode growth of tulips. Endogenous levels of IAA in the 4th internode after the treatment of auxin polar transport inhibitors were determined using gas-liquid chromatography-mass spectrometry (GC-MS) and gas-liquid chromatography-mass spectrometry selected ion monitoring system (GC-SIM) with deuterium labelled IAA (Indole-2,4,5,6,7-d5-3- acetic acid, d5-IAA) as an internal standard, resulted in significant accumulation of IAA in the 4th internode of tulips after the treatment of morphactin. In the treatment of NPA and TIBA, there was almost no such an accumulation of IAA. These results strongly suggest that stimulated growth of the 4th internode of tulips induced by the application of morphactin is the consequence of accumulated endogenous levels of IAA after the treatment. The possible mode of action of auxin polar transport inhibitors in tulip stem growth is also discussed.

Published: June 2013

Background HIV-induced CD4+ and CD8+ T-cell apoptosis decreases upon start of combination antiretroviral therapy (cART). Although in vitro evidence suggests an anti-apoptotic effect of protease inhibitors (PIs) as opposed to non-nucleoside reverse transcriptase inhibitors (NNRTIs), in vivo studies are inconclusive about effects of differential cART regimens on T-cell apoptosis. Methods Peripheral T-cell apoptosis was evaluated in a cross-sectional study including 20 patients on PI-and 19 on NNRTI-based combination antiretroviral therapy (cART), all with backbone therapy of tenofovir and emtricitabine and undetectable viral loads 6 months before inclusion. Spontaneous T-cell apoptosis was measured in freshly isolated peripheral blood mononuclear cells (<4 h after venipuncture) using annexin V, propidium iodide and staining for caspase activity and levels of the anti-apoptotic protein Bcl-2. Results The groups were comparable in general- and HIV-specific characteristics. In addition, T-cell activation was similar in both groups. We observed no difference in T-cell apoptosis as measured by annexin V, propidium iodide or caspase staining between PI- and NNRTI-treated patients. Interestingly, the level of anti-apoptotic protein Bcl-2 was higher in PI-treated than in NNRTI-treated patients. Conclusions In this cross-sectional study on HIV-infected patients, direct ex vivo spontaneous T-cell apoptosis rates are not differentially affected by NNRTI- or PI-based cART.

L’auteur montre que par ses origines et par sa vie Jung est un homme de l’entre-deux et à la frontière. En ce sens, il est naturellement plus proche de la pensée orientale qui privilégie le « vide médian » et la créative interaction des opposés, que du cartésianisme qui aime les choses nettes et tranchées. Compte tenu de ces différentes approches, la position du clinicien varie considérablement. Son diagnostic d’où émane son regard sur le symptôme, peut ainsi figer la relation transférentielle et enfermer le patient ou lui permettre, au contraire, par un certain détour de trouver sa propre voie.

Comment se fabrique et s’entretient le lien social ? À cette question, qui est la question centrale tant de la philosophie politique que de la science économique, de l’anthropologie ou de la sociologie, M. Mauss, héritier intellectuel d’É. Durkheim, répond : par le don. Ou, plus précisément, par l’entrée dans ce qu’il appelle la triple obligation de donner, recevoir et rendre. Par l’obligation d’afficher sa générosité. L’article essaie de prendre la mesure des implications, décisives, de cette découverte, appuyée sur un énorme matériau ethnologique.
Les hôpitaux en quête de rentabilité : à quel prix ?
Authors: Grimaldi André 
Published: June 2013

L’ère scientifique de la médecine, communément appelée « médecine fondée sur les preuves », a permis de définir des normes et procédures. Elle a produit les concepts de « médecine industrielle » et de « médecin ingénieur » qui ont servi à justifier l’application systématique du management d’entreprise à l’hôpital et la généralisation du paiement à l’activité (T2A). Le « business plan » a remplacé la planification sanitaire, la recherche de l’augmentation de l’activité l’impératif éthique du « juste soin », la quête de rentabilité le devoir du « juste coût », les structures de gestion (pôles) les structures de soins (services), la concurrence la complémentarité. La notion de « part de marché » s’est substituée à celle de « besoins ». Cette politique, à peu près adaptée aux gestes techniques simples programmés, s’est fracassée sur la réalité de la médecine, en particulier pour la prise en charge des urgences, des pathologies graves ou complexes et des maladies chroniques, notamment chez les personnes très âgées ou en situation de précarité. La définition d’une politique alternative prenant en compte la pluralité de l’exercice médical ne devra pas s’arrêter au rétablissement dans les textes du service public hospitalier. Elle devra réviser les modes de financement, à l’hôpital comme en ville, condition nécessaire pour une réelle coopération.
Quand l'hôpital se moque de la charité, son compromis fondateur est rompu
Authors: Domin Jean-Paul 
Published: June 2013

Cet article propose une lecture de la crise actuelle du système hospitalier français. Son évolution, depuis le début du XIX e siècle, a été motivée par un objectif de démarchandisation. L’hôpital s’est d’abord construit en opposition au marché de la santé, il a ensuite accompagné le mouvement de socialisation de la dépense de santé, initié à la fin du XIX e siècle. Depuis les années 1980, les réformes favorisent une remarchandisation. La crise actuelle de l’hôpital tient au fait que la logique managériale vient heurter une histoire marquée par l’accueil de toutes les souffrances.
