For a normally distributed variable, the index of atypicality associated with a measurement of that variable is defined as the probability of finding a result closer to the mean of the reference population than the one actually observed. The method extends straight forwardly to multivariate situations, thus providing a joint interpretation of multiple observations recorded on the same subject. In human palaeontology, atypicality indices allow to analyze and to compare the results obtained from variables closely associated with specific traits of the morphology. We briefly outline the principle of the method and give a computer program to carry out the calculations. Finally, we apply the use of univariate and multivariate atypicality indices to data recorded on 53 Upper Palaeolithic skulls. [less ▲]

L'expression de la densité des peuplements forestiers reste l'un des sujets les plus discutés en matière forestière qu'il s'agisse de la qualité des critères proposés ou de la signification même de cette notion. L'objet du présent article est essentiellement de montrer que l'utilisation combinée de paramètres tels que le nombre de bois, la surface terrière, l'arbre de grosseur moyenne et l'âge est de loin préférable à l'utilisation individuelle du nombre de bois ou de la surface terrière, par exemple, tout au moins dans le cas de structures équiennes comparables à celles de l'épicéa dans les Ardennes belges.

Height growth, site index curves and equations for managed even-aged pure stands of douglas-fir under management in the Southern Belgium are presented. They were derived from 256 temporary sample plots, 87 of which were remeasured to give top height periodic increments. The range age and site classes being not equally covered, a special attention was paid to the increments of the total height of dominant trees (1 tree / are of sample plot). A large number of equations were tested to determine which was best suited to express the relationship of age and top height. Regression was employed to fit 4 digitized freehand curves drawn on the average pattern of top heights and top height increments observed at various ages. The form of the JOHNSON-SCHUMACHER model used in this study is : Hdom = b0 exp [-b1/(A-b2)], where : Hdom = top height, A = age, b0, b1 et b2 = coefficients to be estimated by non-linear regression procedures, exp = "e", the base of Naperian logarithms. The coefficients were estimated for the 4 curves. Each of the resulted equations was solved for height at age 50, thereby asigning a site index value to each equation. Site index was introduced into the height-age equation as an independent variable by expressing the coefficients as function of site index itself. Three site index curves corresponding to 36,33 and 30 m attained at age 50 were then derived. The logical issue of this study is to develop a prediction equation based on ecological factors wich should be most correlated with site index. [less ▲]

To test the hypothesis that reactive oxygen species could be associated to the lower airway disorders occurring in horses suffering from recurrent airway obstruction (RAO), indices of oxidative stress were studied in blood and pulmonary epithelium lining fluid in 5 RAO horses either in clinical remission or 24 h after the onset of a crisis of bronchospasm and in 5 healthy horses. Venous blood and bronchoalveolar lavage fluid (BALF) samples were collected and analysed for reduced glutathione (GSH), oxidised glutathione (GSSG), total glutathione (TGSH), glutathione redox ratio (GRR) in blood haemolysate and pulmonary epithelium lining fluid (PELF). The haemolysate concentrations of GSH, GSSG, TGSH and GRR were similar in the 3 groups. The PELF glutathione status was significantly different in the RAO horses in acute crisis compared to healthy horses, indicating the occurrence of an oxidative stress. When RAO horses were in crisis their GSH and TGSH remained unchanged but their GSSG and GRR were significantly increased compared to the remission. These results support the hypothesis that oxidative stress is associated with lower airway disorders occurring in horses suffering from RAO [less ▲]

All Ss completed a battery of psychological tests, and psychological profiles of 16 Ss who died within 3 yrs of testing were compared to those of the surviving Ss. Tests used: The Wechsler Adult Intelligence Scale (WAIS) (1955), L. Bender's Visual Motor Gestalt Test, the Minnesota Multiphasic Personality Inventory (MMPI), R.

A cross-sectional study by means of a questionnaire with open-ended questions and multiple-choice questions was used to collect data on the profile of duck keepers, husbandry practices, and performances, opportunities and constraints of Muscovy duck breeding in households (n = 88) in Dolisie city (Congo-Brazzaville). The study confirmed the common observations on traditional poultry keeping such as scavenging during the day and housing overnight. The flock size (7.7 ± 3 ducks per unit) showed no specialization of husbandry (100% of surveyed flocks were kept for simultaneous production of ducklings, meat and eggs) and a high drake-to-duck ratio (1:3). The hatchability was close to 80.5% ± 13%, whereas the average number of eggs was 13.2 ± 5 per clutch. In addition, a high mortality (80%) was observed in ducklings, which was due to poor feeding, lack of veterinary care and housing conditions. Eggs and live ducks were sold by duck farmers in response to the family needs rather than market price. The three most important findings were as follows: (1) duck keepers were mainly men (80% versus 20% of women); (2) there was no evidence of taboo; and (3) the duck as an exotic bird was not proscribed by cultural beliefs, and therefore development of the Muscovy duck in Congo Brazzaville should be unhindered.

Abstract Objective: Compare the efficacy of bazedoxifene with oral bisphosphonates for reduction of vertebral fracture risk in postmenopausal osteoporotic (PMO) women and in higher-risk patients based on evidence from randomized controlled trials (RCTs). Methods: Eight RCTs assessing vertebral fracture risk reduction with oral bisphosphonates (n = 7) or bazedoxifene (n = 1) were identified by a systematic literature review. Individual study results were pooled in a network meta-analysis (NMA) to indirectly compare treatment effects for overall PMO women and a higher-risk subgroup (FRAX >/= 20%). Three sets of NMA analyses were conducted: aggregate data (AD) from the bisphosphonate RCTs and bazedoxifene RCT for the full population or the FRAX >/=20% subgroup (NMA AD); bisphosphonate AD and bazedoxifene AD from each FRAX subgroup adjusted for baseline risk (NMA AD meta-regression); and bisphosphonate AD and bazedoxifene individual patient data (IPD) adjusted for baseline risk/FRAX (NMA AD/IPD meta-regression). Results: For the overall population, bisphosphonates had lower fracture risks versus bazedoxifene although there is considerable uncertainty in supporting one intervention over another. The relative risk reduction (RRR) for bazedoxifene was -0.23 (95% CrI: -1.11, 0.27) versus ibandronate, -0.17 (-0.76, 0.22) versus alendronate, and -0.06 (-0.62, 0.30) versus risedronate. Results from the meta-regression analyses were similar. For the FRAX >/=20% population, estimated fracture rates with bazedoxifene were lower than with bisphosphonates, but again the uncertainty limits strong interpretation. The RRR for bazedoxifene was 0.51 (-0.31, 0.83) versus ibandronate, 0.53 (-0.18, 0.83) versus alendronate, and 0.57 (-0.07, 0.85) versus risedronate. The meta-regression analyses showed comparable findings. Conclusion: The analyses only considered vertebral fractures for oral bisphosphonates versus bazedoxifene, and IPD was available only for bazedoxifene. In light of this, bazedoxifene is comparable to bisphosphonates in the overall PMO population and at least as effective as bisphosphonates for preventing vertebral fractures among higher-risk PMO patients. The findings suggest bazedoxifene performs better in higher-risk PMO than in the overall PMO. [less ▲]
