Aim of the study: Injections of platelet-rich plasma (PRP) constitute a new therapeutic for treating chronic tendinopathies. The injection being carried out in the tendon, the volume of PRP should thus be minimal (to decrease the intra-tendinous pressure and to minimize pain). This PRP should also have a raised platelet count. The quantity of released growth factors could be related to the system of preparation employed. We thus carried out a comparative study of 5 techniques of preparation of PRP described in the literature. Patients and methods: Samples of venous blood were taken among 5 patients in order to compare 5 techniques of preparation of PRP: University Hospital of Liège technique, Curasan® PRP Kit, Plateltex®, GPS® and RegenLab®. Results: The various techniques make it possible to obtain more important platelet concentration than in blood, with variable volumes (0,3 mL to 6 mL). The number of platelets/microlitre appears higher with Plateltex® and obtains smallest volume of PRP. The other techniques also give small volumes excepted for the GPS® II. The number of collected platelets with this technique appears thus higher. The best collect efficiency is obtained with RegenLab®. Conclusion: The technique Plateltex® makes it possible to collect the highest concentration of platelets in the smallest volume available. [less ▲]

The aim of the study is to test the relative efficiency of sampling plots including a predetermined number of trees. Such a concept implies that the plot area itself is variable from stand to stand. We have considered 18 types of sampling plots : 11 based upon a fixed number of trees (from 5 to 15), 2 based upon an estimated number of trees (10 and 15) all of them being compared with 5 more traditional procedures (fixed areas of 2, 4, 6, 8 and 10 ares). All the samples have been considered in 154 points located at random in various spruce stands. When comparing estimates of number of trees, basal area and volume per hectare in stands characterized by a mean girth less than 90 - 100 cm, we have observed that the plots including 15 trees were very interesting to consider according to cost and precision. Concerning the estimation of the mean girth a plot based upon 6 fixed trees is quite acceptable. [less ▲]

In forest inventory, if the sampling unit is of fixed area it is necessary to choose its shape and size. In such a way we are testing 5 circular plot sizes (2, 4, 6, 8 and 10 ares) by means of more than 150 inventory points located in normally stocked forests. The five sizes give identical results from means point of view but according to relative efficiencies, it seems to be realistic to recommand sample plots of 2 or 4 ares, when stands are less or more than 70 years aged.

This study is dealing with the choice of the size and the type of sampling units to be used in inventories of beech stands (Fagus sylvatica L.), located in the Southern part of Belgium. In most cases the stands are evenaged or unevenaged according to the places. We have considered 3 types of units : fixed circular plots (5 to 20 ares), circular plots including a fixed number of trees (6 to 15 trees) and circular plots including a minimum number of trees (from 15 to 20). From efficiency point of view, we conclude that dominant girth and top height estimations are the best ones when measuring the 2 biggest trees in a circular plot area of 5 ares, while mean girth and mean volume estimations are worth considering when based upon the ten nearest trees from the point sample. The concept of the minimum number of trees is valuable in case of estimating number of trees, basal area and volume per hectare. [less ▲]

L’indice de détection de patrons de réponses inappropriés Lz (Drasgow, Levine et Williams, 1985) est fort probablement l’indice le plus connu et le plus utilisé par les patriciens et les chercheurs en mesure. Ainsi, on a surtout étudié le comportement de Lz lorsqu’il est utilisé avec des données dichotomique mais il est aussi possible de l’analyser avec des données polytomique. Dans le cadre de cette recherche, nous proposons de comparer les résultats des indices Lz dichotomique et Lz polytomique. Pour ce faire, (i) nous utiliserons l’indice Kappa de Cohen pour comparer si les patrons de réponses détectés entre les deux versions de l’indice sont les mêmes et (ii) nous étudierons leur distribution respectives.
