BACKGROUND In North-African adults, location-specific reference values for membrane diffusion capacity (D(m)) and pulmonary capillary blood volume (V(c)) were needed. OBJECTIVES To verify the applicability of previously published reference equations for D(m) and V(c) in North-African healthy adults (age >18 years) and to determine specific reference equations for North Africa. METHODS The s...

BACKGROUND A clinical need exists to improve identification of those who will sustain fragility fractures. Individuals with both osteoporosis (OP) and sarcopenia (SP), so-called "sarco-osteoporosis" (SOP), might be at higher fracture risk than those with OP or SP alone. Approaches to facilitate SOP identification, e.g., use of tallest historical rather than current height and inclusion of radiu...

By adapting data from national and state champion lists and the predictions of an existing height model, an exponential function was developed to improve tree height estimation. As a case study, comparisons between the original and redesigned model were made with eastern white pine (Pinus strobus L.). For example, the heights predicted by the new design varied by centimeters from the original u...

Estimating forest canopy height from large-footprint satellite LiDAR waveforms is challenging given the complex interaction between LiDAR waveforms, terrain, and vegetation, especially in dense tropical and equatorial forests. In this study, canopy height in French Guiana was estimated using multiple linear regression models and the Random Forest technique (RF). This analysis was either based o...

We measured gas exchange and various leaf parameters of ash (Fraxinus angustifolia Vahl.) and oak (Quercus robur L.) in the high canopy and of lime (Tilia cordata Mill.) in the lower canopy of a planted, 120-year-old floodplain forest in southern Moravia, Czech Republic. The high-canopy leaves of F. angustifolia and Q. robur had nitrogen concentrations on a leaf area basis (N(area)) that were t...

Let n ≥ 0 be any integer and let Fn := { n ∑ i=0 aiz i : ai = 0,±1 } be the set of all polynomials of height 1 and degree n. Let βn(m) := 1 3n+1 ∑ P∈Fn ‖P‖m. Here ‖P‖m is the mth power of the Lm norm on the boundary of the unit disc. So βn(m) is the average of the mth power of the Lm norm over Fn. In this paper we give exact formulae for βn(m) for various values of m. We also give a variety of ...

—This study assessed how sex of participant is related to electromechanical delay during a karate punch. Ten male (M age = 25.00 yr., SD = 3.02; M height = 174.9 cm, SD = 6.3; M weight = 71.13 kg, SD = 9.35) and 8 female (M age = 27.4 yr., SD = 6.0; M height = 161.4 cm, SD = 5.1; M weight = 59.09 kg, SD = 7.00) karate athletes performed 10 ballistic punches to a target as hard as possible. Kine...

Characteristics and behavior of the flow in hydraulic structures, a complex phenomenon that isimperative to use software that will beto be study.Gabiony stepped spillway is a simple hydraulicstructures to control erosion downstream of dams, and, depreciation of structures is used. Roughstairway consisting of overflow from the stairs near the crest of the weir is started and continues tohave a l...

1. (a,b)-Trees As we saw in the previous section, the efficiency of standard operations on binary search trees depends on the maximum tree height. Using height balancing, we ensure that trees cannot degenerate linearly but instead have logarithmic height. Let us extend this approach to more general trees. Motivation: assume tree nodes are stored in secondary storage (hard disk). Comparisons of ...
