To estimate the order of importance of factors affecting the stability and maturation of compost, pig feces and corn stalks were co-composted at different aeration rates (AR: 0.24, 0.48, 0.72 L kg(-1)dry matter (DM)min(-1)), C/N ratios (15, 18, 21), and moisture contents (MC: 65%, 70%, 75%). The thermophilic phase with all treatments was long enough to meet sanitation requirements. The oxygen c...

Experiments are described in which static and dynamic accommodation (Ar), accommodative convergence (AC), vergence (C) and convergence accommodation (CA) responses to small stimuli were measured dynamically in 13 subjects with ages in the range 16 to 48 years. Analysis showed that the amplitudes of both blur and disparity-driven accommodation declined significantly with age, whereas the two typ...

BACKGROUND Recently, the use of hypo-fractionated treatment schemes for the prostate cancer has been encouraged due to the fact that alpha/beta ratio for prostate cancer should be low. However a major concern on the use of hypofractionation is the late rectal toxicity, it is important to be able to predict the risk of toxicity for alternative treatment schemes, with the best accuracy. The main ...

FeN thin films were deposited on glass substrates by dc magnetron sputtering at different Ar/N2 discharges. The composition, structure and the surface morphology of the films were characterized using X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and atomic force microscopy (AFM). Films deposited at different nitrogen pressures exhibited different structures with different nit...

In percutaneous orthopedic interventions the surgeon attempts to reduce and fixate fractures in bony structures. The complexity of these interventions arises when the surgeon performs the challenging task of navigating surgical tools percutaneously only under the guidance of 2D interventional X-ray imaging. Moreover, the intra-operatively acquired data is only visualized indirectly on external ...

Background and Objective: Childhood obesity is one of the major national health concerns. World Health Organisation (WHO) recommends Body mass index (BMI) as the standard epidemiological measurement of obesity. The BMI is not quite independent of stature, especially at the younger ages. Hence, an alternative tool like arm-circumference-to-height ratio (AHtR) is necessitated. The aim of this stu...

an inversion procedure is used to obtain from the extended principle of corresponding - states the pair interaction potentials for argon, krypton and its mixture over a tetnperature range from absolute zero to the onset of ionization. the experimentally-reduced viscosity collision integrals obtained from the corresponding - states correlation have been inverted directly to give the reduced-inte...

OBJECTIVES Assessment of aortic regurgitation (AR) immediately after transcatheter aortic valve replacement (TAVR) is essential to guide further intervention in cases of relevant AR. It was the aim of this study to identify a simple and reproducible hemodynamic parameter for the assessment of AR. BACKGROUND Relevant AR after TAVR is present in up to 21% of cases and might be associated with a...

Increased gravity impairs pulmonary distributions of ventilation and perfusion. We sought to develop a method for rapid, simultaneous, and noninvasive assessments of ventilation and perfusion distributions during a short-duration hypergravity exposure. Nine sitting subjects were exposed to one, two, and three times normal gravity (1, 2, and 3 G) in the head-to-feet direction and performed a reb...

Flow features and forces of three-dimensional flapping foils are presented with aspect-ratio (AR) variations. The similitude rolling twisting kinematics is maintained across different ARs. An AR correction analogous to Prandtl finite-wing theory developed, enabling future use strip in the analysis design finite foils.
