AN OCCURRENCE OF SAPPHIRINE IN THE ARCHEAN SUPERIOR PROVINCE, NORTHERN QUEBEC

A clast containing sapphirine has been found in the Troie Complex in the Archean Minto Subprovince, in the northeastern part of the Superior Province, in northern Quebec. The area is dominated by synmagmatically deformed felsic plutonic rocks that host volcano-sedimentary slivers and rafts. The Douglas Harbour Domain contains the Faribault–Thury tonalite–trondhjemite complex, intruded by the 2740–2726 Ma enderbitic Troie Complex. Slivers and enclaves of volcano-sedimentary rocks in the Troie Complex are metamorphosed to granulite grade. A breccia in the core of the Troie Complex contains a heterogeneous population of xenoliths in an enderbitic matrix. The clast contains sapphirine as symplectitic rims with plagioclase or K-feldspar (or with both) developed around sillimanite and cordierite. Sapphirine also forms a corona around green hercynite, with K-feldspar rimming the sapphirine. Reaction textures, annealing and polygonization indicate localized equilibration, with mosaic equilibrium preserved on the thin-section scale. Various geothermobarometers yield estimates of high temperatures (755–1260°C) and pressures (7.5–14 kbar). The existence of localized equilibria is difficult to interpret in terms of simple prograde or retrograde metamorphism linked with orogenesis. Either static P–T conditions for a protracted period, or minimal attainment of granulite-facies conditions are required to produce and preserve these mosaic textures.
A Dental Practice Analysis in the Area of Port-au-Prince: A View on the Integrated Periodontal Care Approach

The aim of this study was to identify and evaluate some structural aspects of the dental care supply and demand, its mechanism and then characterizes the periodontal preventive activity in the region of Port-au-Prince. We had conducted between January and February 2012 an epidemiological survey, using a questionnaire that we had administered tothe dentists operating in Port-au-Prince. Our analysis of 230 questionnaires revealed a dental practice that is almost private and which is largely carried out by men. Our results also indicated that the dentist population in this region happens to be quite young. Most of the demands resulting from dental consultation are related topain or bleedings. The preventive periodontal act was the most practiced.Althoughmany interventions has been performed in periodontal surgery. Practitioners in the two categories think that a reference should be addressed in severe cases and even if the number of years of experience affect their position towards the built-in support.A fact is that the two groups are agreed that this type of approach is the ideal.
Comparison of Academic Motivation of Academically Prepared and Academically Unprepared Community College Students

Community colleges across the nation have the challenge to educate students who come to postsecondary education at varying levels of academic preparedness. Cross (2001) and others (Agbor-Baiyee, 1997; Dweck, 2000; Hamilton, 1996; Hynd, Holschuh, & Nist, 2000; Miller, DeBacker, & Green, 1999; Struthers & Menec, 1996; Tuckman, 1996; Yair, 2000) have reported on the importance of motivation and its relationship to student learning. Although the research has proven to be of great value, it often excludes a comparison of academic preparedness and the impact academic preparedness may have on motivation. This study compared academic motivation between academically prepared and academically unprepared community college students. In addition, the researcher collected data to determine whether a relationship exists between academic motivation level and academic achievement as defined by grade point average. Surveying students from a community college in northwest Florida, the Academic Motivation Scale (AMS-C) was used to assess motivation along a continuum as described by Deci and Ryan’s (1985) self-determination theory. Results from this study indicate that there are motivational similarities between academically prepared and academically unprepared students and that there is a relationship between motivational levels and academic success.
Scale-up and Process Transfer of Freeze-Drying Recipes

This paper proposes a simple and effective methodology for the scale-up and process transfer of freeze-drying recipes. Process modeling allows the study of the silico product evolution in a given freeze-dryer, and calculation of the operating conditions that result in the same product dynamics in different equipment. Few experiments are necessary to determine model parameters and to characterize the two freeze-dryers. The problem of the batch non-uniformity and the effect of the parameters' uncertainty are also addressed. The effectiveness of this approach is demonstrated by means of various examples.
The effects of variations in the implementation of a stepwise managerial strategic crisis model and corporate reputation capital on post-crisis share price values: A qualitative and quantitative analysis of specific South African companies

The paper proposes a structured, stepwise approach to the management of reputational risks in order to assist in defining strategies for crisis management. A series of case studies of selected South African firms’ responses to specific crises in comparison to an ideal type stepwise model were analyzed and the effects on specific share price values explored. The effect of reputation capital on share price values, six months after the crises each of the selected companies sustained was also investigated. Correlation analyses tentatively indicated that the number of steps taken by management in the companies concerned in conformance with the model, and the speed with which they were implemented, affected post-crisis average share price values. Corporate capital as measured by perceptions of reputation and brand strength, were also found to be associated with greater company post–crisis share price resolution. Key words: Crisis management, ideal type model, case study analysis, share price, reputation capital.
COSMIC REIONIZATION AFTER PLANCK: COULD QUASARS DO IT ALL?

We assess a model of late cosmic reionization in which the ionizing background radiation arises entirely from high-redshift quasars and other active galactic nuclei (AGNs). The low optical depth to Thomson scattering reported by the Planck Collaboration pushes the redshift of instantaneous reionization down to z = 8.8 − 1.4 + 1.7 ? > and greatly reduces the need for significant Lyman-continuum emission at very early times. We show that if recent claims of a numerous population of faint AGNs at z = 4–6 are upheld and the high inferred AGN comoving emissivity at these epochs persists to higher, z ≳ 10, redshifts, then active galaxies may drive the reionization of hydrogen and helium with little contribution from normal star-forming galaxies. We discuss an AGN-dominated scenario that satisfies a number of observational constraints: the H i photoionization rate is relatively flat over the range 2 < z < 5, hydrogen gets fully reionized by z ≃ 5.7, and the integrated Thomson scattering optical depth is τ ≃ 0.056, in agreement with measurements based on the Lyα opacity of the intergalactic medium (IGM) and cosmic microwave background polarization. It is a prediction of the model that helium gets doubly reionized before redshift 4, the heat input from helium reionization dominates the thermal balance of the IGM after hydrogen reionization, and z > 5 AGNs provide a significant fraction of the unresolved X-ray background at 2 keV. Singly and doubly ionized helium contribute about 13% to τ, and the He iii volume fraction is already 50% when hydrogen becomes fully reionized.
Effect of integrated weed management on weed control and yield components of maize and cassava intercrop in a southern Guinea savanna ecology of Nigeria.

The use of pre-emergence herbicides, hoe weeding and live mulch of herbaceous cover plants in a maize/cassava intercrop was investigated at the Teaching and Research Farm of the University of Ilorin, in 2002 and 2004. Experiment consisted of eight main treatments and six sub treatments. The main treatments which is the focus of this article were made up of the application of two pre-emergence herbicides [Primextra and Galex, each at 2.5 kg a.i./ha alone or with one or two supplementary hoe weedings at 6 weeks after planting (WAP) or 6 and 12WAP], a hoeweeded check (hoeing at 3, 6 and 12WAP) and a weedy control. The experiment was laid out in a randomized complete block design with a criss-cross arrangement, and replicated three times. Data were collected for weed infestation and control, as well as for yield of food crops. When used alone, the pre-emergence herbicides gave satisfactory weed control up to 6WAP, but failed to give season-long weed control. However, better weed control was achieved when the pre-emergence herbicides were supplemented with two hoe-weedings, (P<0.05). Consequently, Primextra plus two hoe weedings (Prim+2HW) gave significantly lower weed biomass (42.9 g/m²) and higher yields of the food crops (1135 kg/ha for maize and 10,027 kg/ha for cassava) compared with the hoeweeded control treatment (63.0 g/m², weed biomass; 849 kg/ha, maize and 8076 kg/ha, cassava), plots treated with Primextra alone (80.4 g/m², weed biomass; 678 kg/ha, maize; 1801 kg/ha, cassava) and the weedy control (116.3 g/m², weed biomass; 358 kg/ha, maize and 1425 kg/ha, cassava).
Simulation of supersonic flow: comparison of LES against URANS and RANS turbulence models

This study aims to analyze the influence of different turbulence models in capturing the flow profile in supersonic nozzles as ones used in steam jet ejectors. Based on the recent experiments by T. Sriveerakul. ; S. Aphornratana. ; K. Chunnanond (International Journal of Thermal Sciences 46 (2007) 812-822) computations were performed using three different turbulence models, a modified RANS model (SST k-ω), a URANS model with Scale Adaptative S imulation - SAS and the large eddy simulation (LES), with three different steam jet operational conditions, the simulation results were compared with experimental data. First, SAS and SST k-ω computations were performed with three meshes with different refinement level on a mesh independency study. It was observed that SAS model was more sensitive with mesh refinement. In less refined mesh the pressure profile obtained was very close to SST k-ω results indicating that mesh refinement and time st ep weren't enough to activate the source term included in ω. With two other meshes a SAS convergence was o bserved while these meshes are refined enough to use LES. LES time average values of the variables under study on the most refined mesh were included in the comparison. Furthermore Mach number plots along the equipment center line showed the shock waves formation and the pressure profile recuperation that occurs in the diffuser. The RANS SST k-ω turbulence model results showed the smallest errors related to the experimental data.
Impact of pesticide residues on fertility of dairy animals: A review

Dairy animals are exposed to a number of pesticides during lifetime. Although, the level of exposure of individual pesticide is usually too low to induce any acute impact on reproductive system, but the combinations of pesticide residues can act additively or synergistically to cause chronic disturbances in hypothalamo-pituitary-gonadal system at all ages and especially in the developing fetus/neonates. The concern is increasing regarding the ability of some pesticide residues, known as endocrine-disrupting chemicals, to disrupt the synthesis, function and metabolism of reproductive hormones. At present, many potential sites of action of pesticide residues have been identified but the knowledge regarding long-term synergistic impact of pesticide residues on reproductive systems is poor especially in dairy animals. The pesticide residues can impair semen quality, as well as female fertility. The present paper identifies the risks to fertility of dairy animals posed by wide spread contamination of our environment with pesticide residues.
Comparative sport injury epidemiological study on a Spanish sample of 25 different sports

Sport injury is a widely extended morbidity condition. However, epidemiological studies are far from giving a convergent outlook. Moreover, there is a lack of studies comparing relative risks of different groups of sports. The present paper is aimed to carry out a descriptive epidemiological study of sport injuries of athletes from 25 sport modalities in order to identify risk factors as well as to compare epidemiological characteristics according to the different sport groups. A sample of 297 athletes from different sport federations in the region of Madrid (Spain) were assessed using a protocol comprising a section about the sport being practiced and a section about injury incidence. Due to the wide variety of sport modalities, the sample was classified into four groups according to the Blazquez and Hernandez Moreno's (1984) sports classification. Results showed no gender but age differences in injury incidence. They also showed differences in terms of injury frequency and severity (elapsed time between the injury and the returning to sport practice) among sport groups, being athletes practicing co-operation-opposition sports those who seemed to be more at risk. There were also differences regarding internal/external causes and when the injury was sustained. The global exposure injury rate (training and competition) rose to 4.1 injuries/1.000 hours. Sport injury is a morbidity condition any athlete is inevitably going to face during his/her sport career (Almeida, Olmedilla, Rubio and Palou, 2014). Moreover, sport injury nowadays appears not only in professional and semi-professional sport but also in amateur, leisure and even in introduction to sport (Pipe, Junge, Charles and Dvorak, 2005). This is probably due to the generalization of the practice of physical activity, the extension of professionalization and the increase in competitiveness (Bahr
Degradation changes stable carbon isotope depth profiles in palsa peatlands

Palsa peatlands are a significant carbon pool in the global carbon cycle and are projected to change by global warming due to accelerated permafrost thaw. Our aim was to use stable carbon isotopes as indicators of palsa degrada- tion. Depth profiles of stable carbon isotopes generally reflect organic matter dynamics in soils with an increase of 13 C values during aerobic decomposition and stable or decreas- ing 13 C values with depth during anaerobic decomposition. Stable carbon isotope depth profiles of undisturbed and de- graded sites of hummocks as well as hollows at three palsa peatlands in northern Sweden were used to investigate the degradation processes. The depth patterns of stable isotopes clearly differ between intact and degraded hummocks at all sites. Erosion and cryoturbation at the degraded sites signif- icantly changes the stable carbon isotope depth profiles. At the intact hummocks the uplifting of peat material by per- mafrost is indicated by a turning in the 13 C depth trend, and this assessment is supported by a change in the C / N ratios. For hollows isotope patterns were less clear, but some hol- lows and degraded hollows in the palsa peatlands show dif- ferences in their stable carbon isotope depth profiles indicat- ing enhanced degradation rates. We conclude that the degra- dation of palsa peatlands by accelerated permafrost thawing can be identified with stable carbon isotope depth profiles. At intact hummocks 13 C depth patterns display the uplifting of peat material by a change in peat decomposition processes.
Risk and Probability Premiums for CARA Utility Functions

The risk premium and the probability premium are used to determine appropriate coefficients of absolute risk aversion under CARA utility. A defensible range of risk aversion coefficients is defined by the coefficients that correspond to risk premiums falling between 1 and 99% of the amount at risk or to probability premiums falling between . 005 and . 49 for a lottery that pays or loses a given sum. The consequences of ignoring risk premiums when selecting risk-aversion coefficients for representative decision makers are illustrated by calculation of the implied risk premium associated with the levels of absolute risk aversion assumed in six selected studies.
Chrysoporthe, a new genus to accommodate Cryphonectria cubensis

Cryphonectria cubensis is an important canker pathogen of tree species residing in the Myrtaceae and Melas- tomataceae. Recent phylogenetic studies based on multiple gene sequence comparisons have revealed that isolates of C. cubensis group separately from other Cryphonectria species. Within the C. cubensis clade, isolates formed three distinct sub- clades that include isolates mainly from South America, South Africa and South East Asia, respectively. In this study, we establish a new genus, Chrysoporthe, for this species. Chrysoporthe is characterized by superficial, blackened conidiomata, limited ascostromatic tissue, and blackened perithecial necks protruding from the orange stromatal surface. Although speci- mens of C. cubensis from South East Asia and South America reside in two distinct phylogenetic sub-clades, they could not be separated or distinguished from the type specimen, originating from Cuba, based on morphological characteristics. For the present, these specimens are collectively transferred to Chrysoporthe as a single species, Chrysoporthe cubensis. Specimens previously treated as C. cubensis from South Africa reside in a discrete phylogenetic clade and could be distinguished from those in the other sub-clades based on having longer asci and ascospores with rounded apices as opposed to tapered apices. The South African fungus is described as Chrysoporthe austroafricana. Isolates from Tibouchina spp. in Colombia resided in a fourth sub-clade of Chrysoporthe. Isolates in this phylogenetic assemblage grew optimally at 25 °C in contrast to those in the other groups that grew optimally at 30 °C. No sexual state is known for the fungus in this fourth sub-clade and a new anamorph genus and species name, Chrysoporthella hodgesiana, is provided for it.
Pregnant and Parent Teens Matter Too

The purpose of this study was to describe the experiences of parenting and pregnant teens, school staff, and participant’s parents with the Support for Pregnant and Parenting Teens Program (SPPT) within two highschools in an inner-city school district. To achieve this aim, focus groups and individual interviews were used to qualitatively explore the experiences of students (n=18), their parents (n=5), and school personnel (n=5). SPPT aims to improve educational and health outcomes for expecting mothers and parenting teenagers and their children. For pregnant and parenting teens, this school-based program indicated promising outcomes in the following areas: engaging and supporting students, increasing academic achievement, accessing health services for parent and child, and improving attendance rates.
Foreign direct investment and productivity spillovers in the Central and Eastern European countries

The paper discusses the inflows of foreign direct investment into the CEE countries and focuses on analysis of productivity spillovers. Overview of the relevance of foreign firms in the CEE economies is presented. Using firm-level data on manufacturing industries for the period 2000-2005, total factor productivity of domestic firms is estimated using Petrin and Levinsohn (2003) method and subsequently related within a panel data model to foreign presence in the same industry and in the industries linked via production chain. Presence of productivity spillovers is tested across several breakdowns to detect possible conditionalities.
Treatment Of Heart Failure In A Teaching Hospital In Ghana, West Africa

This study was done to compare the treatment of heart failure at the Komfo Anokye Teaching Hospital (KATH), Kumasi, with the European Society of Cardiology (ESC) guidelines for the treatment of heart failure. Patients above twelve years admitted to the medical wards with heart failure were recruited. Detailed history was obtained. Clinical examination, and laboratory investigations were done. Treatments received by the patients whilst on admission were studied and compared with the ESC guidelines for the treatment of heart failure. Hundred patients were studied; 52 males and 48 females, aged 14-100 years with mean 56.15 ( 18.50) years. Every patient received frusemide. ACE-I were used in 83.3%, 51.7 % and 55.4 % of the patients with NYHA classes II, III, and IV respectively. Beta-blockers were used in 33.3%, 20.7% and 12.3% of patients with NYHA classes II, III and IV respectively. In conclusion, frusemide and ACE-I were the two most common drugs prescribed.

Corporate Boards in OECD Countries: Size, Composition, Functioning and Effectiveness

In recent years, the debate about the efficiency of corporate governance mechanisms has focused on the activity of the corporate boards of directors. This paper analyses the effect of the size of the board, its composition and internal functioning on firm value in a sample of 450 non-financial companies from ten countries in Western Europe and North America. The econometric method combines uniequational regression analysis with simultaneous equations in order to control for the possibility of board size and composition endogeneity. The results show a negative relationship between firm value and the size of the board of directors. This relation holds when we control for alternative definitions of firm size and for board composition, the board's internal functioning, country effect and industry effect. We find no significant relationship between the composition of the board and the value of the firm. These results are consistent with previous relevant papers and show that companies with oversized boards of directors have poorer performance both in countries where internal mechanisms of governance dominate and in countries where external mechanisms are predominant.
The motivation to use oral language in the EFL classroom in ESO and Bachillerato

The students' general inhibition to use L2 in the classroom is a reality which every teacher has experienced. The purpose of this research is to observe and describe the reasons for this reality from the students' perspective and obtain some conclusions which can help teachers to improve the situation. A survey was passed among students of ESO and Bachillerato as well as among their teachers. This showed that students must be intrinsically motivated and the teacher must help them to raise their self- worth and reach autonomy. This seems to be the most important factor although there are some others such as interactive pattern, feedback and the role of the teacher itself. The reality reflected by the surveys is totally opposed to the most current methodological tendencies.
