BACKGROUND To evaluate a combined rheumatoid arthritis magnetic resonance imaging score (RAMRIS) for hand and foot (HaF-score) in rheumatoid arthritis (RA). METHODS Magnetic resonance imaging (MRI, 0.2 Tesla) of the dominant hand and foot of 26 ACPA positive RA patients before and 6 months after initiation of methotrexate was obtained. RAMRIS of the hand was complemented by corresponding scor...

Different types of annual and perennial crop species have been detected in cropland agroforestry (CAF), homestead (HAF) cropping (AC) system four Upazilas (Bagha, Charghat, Puthia Tanore) under Rajshahi district Bangladesh. The objectives the study were to assess compare farmer’s preference different agroforestry, systems, find out financial values among systems. sample size was 150 small farme...

We report on optical linear birefringence measurements in the nearly ideal S = 1 Heisenberg antiferromagnetic chain compounds: Ni(C2HsN2)2 NO2 (C104) and Ni (CzHsNz)2 N02PF6. The temperature dependence of the magnetic contribution, proportional to that of the magnetic energy, indicates J / k = -53 K and supports the Haldane conjecture. Considerable interest has been recently stimulated by Halda...

Anti-Müllerian hormone (AMH) has been observed to decrease with the development of hemorrhagic anovulatory follicles (HAFs) in mares. Two studies were conducted to evaluate AMH concentration in mares with HAFs compared to seasonally anoestrous and cyclic mares, and to elucidate changes of AMH with the development of luteinised unruptured follicles (LUFs). In study 1, AMH and progesterone were e...

We consider the problem of estimating the Doppler shift and rate of a linearly modulated digital signal subject to time-selective Rician fading. We derive the Cram er-Rao bounds for the parameters; we propose an estimator, based on the Higher-order Ambiguity Function (HAF), and show that it is consistent. We also establish some interesting results in the context of estimating the parameters of ...
