Determinação do habitat potencial de Asphodelus bento-rainhae P. Silva com recu...

Asphodelus bento-rainhae P. Silva é uma espécie de Liliaceae, endémica da serra da Gardunha (Fundão). A sua área de distribuição ocupa cerca de 700 ha, exclusivamente na vertente norte, entre 530 a 810 m de altitude, em solos profundos resultantes de depósitos de vertente de corneanas e xistos mosqueados derivados de metaformismo de contacto dos xisto-grauvaque, repartindo-se por sete freguesias do concelho do ...

Comportamento ingestivo de caprinos das raças Moxotó e Canindé em confinamento ...

Neste trabalho foi avaliado o comportamento ingestivo de caprinos nativos do semiárido nordestino mantidos em confinamento. Foram utilizados 40 machos castrados, 20 da raça Moxotó e 20 Canindé, com peso médio inicial de 15,22 kg ± 1,78 kg, distribuídos aleatoriamente em delineamento inteiramente casualizado, em arranjo fatorial 2 × 2, com duas raças e duas dietas. Foram avaliadas duas dietas experimentais: uma ...

Alloxan-induced diabetes delays repair in a rat model of closed tibial fracture

A closed fracture was performed on the left tibia of 3-month-old Wistar rats weighing 250 to 350 g that were either healthy (N = 24) or made diabetic with alloxan (N = 24) to investigate the effect of alloxan-induced diabetes on the course of bone fracture healing. Histomorphometric analysis of the fracture site was performed at 7, 14, 25, and 35 days. After 7 days, diabetic rats had significantly less cartilag...

On the HHT, its problems, and some solutions

Mechanical Systems and Signal Processing, Vol.22, Number 6 ; The empirical mode decomposition (EMD) is reviewed and some questions related to its effective performance are discussed. Its interpretation in terms of AM/FM modulation is done. Solutions for its drawbacks are proposed. Numerical simulations are carried out to empirically evaluate the proposed modified EMD.

On the relation between the fractional Brownian motion and the fractional deriv...

Physics Letters A, vol. 372; Issue 7 ; The definition and simulation of fractional Brownian motion are considered from the point of view of a set of coherent fractional derivative definitions. To do it, two sets of fractional derivatives are considered: (a) the forward and backward and (b) the central derivatives, together with two representations: generalised difference and integral. It is shown that for thes...

Mössbauer spectroscopy and X-ray diffraction studies of ball-milling-induced tr...

57Fe Mössbauer spectroscopy and X-ray diffraction were used to study the structural changes induced by ball milling a coarse-grained Fe48.1V51.9 at% sigma phase in a vibratory mill in argon with a frequent gas renewal. The sigma phase transforms into a bcc alpha phase till 140 h of milling. Mössbauer spectroscopy also shows the presence of an amorphous phase. Further, X-ray diffraction and Mössbauer spectroscop...
