Exercise intolerance is a feature of chronic heart failure (CHF). We hypothesized that excessive loading of the respiratory muscle pump might contribute to exertional breathlessness. One marker of excessive muscle-loading is slowing of maximum relaxation rate (MRR) and, therefore, to test our hypothesis, we investigated the effect of exhaustive treadmill walking on inspiratory muscle MRR in pat...
Sparse representation techniques for robust face recognition have been widely studied in the past several years. Recently face recognition with simultaneous misalignment, occlusion and other variations has achieved interesting results via robust alignment by sparse representation (RASR). In RASR, the best alignment of a testing sample is sought subject by subject in the database. However, such ...
BACKGROUND Depression is common after a cancer diagnosis and is associated with an increased mortality, but it is unclear whether depression occurring before the cancer diagnosis affects cancer mortality. We aimed to study cancer mortality of people treated with antidepressants before cancer diagnosis. METHODS AND FINDINGS We conducted a population based cohort study of all adults diagnosed w...
Background. There are limited data on clinical outcomes of hepatitis C virus (HCV) infection from low- and middle-income countries. We characterize mortality and liver disease progression in a cohort of people who inject drugs (PWID) with high HCV burden. Methods. In a cohort of PWID in Chennai, India, 851 persons were observed semiannually. Information on death was obtained through verbal au...
BACKGROUND In contrast to the case fatality rate of patients diagnosed with meningococcal disease (MD) the long-term mortality in these patients is poorly documented. METHODOLOGY/PRINCIPAL FINDINGS We performed a nationwide, population-based cohort study including all Danish patients diagnosed with MD from 1977 through 2006 and alive one year after diagnosis. Data was retrieved from the Danis...
BACKGROUND Women are reported to have greater mortality after stroke than men, but the reasons are uncertain. We examined sex differences in mortality at 1 and 5 years after stroke and identified factors contributing to these differences. METHODS AND RESULTS Individual participant data for incident strokes were obtained from 13 population-based incidence studies conducted in Europe, Australas...
In the laser cutting process some well-known parameters, e.g. laser power and cutting speed, play major roles in the performance of the process. Each parameter or a combination of parameters can affect the material removal volume and cutting volume efficiency. The purpose of this research is to study the effect of power and maximum cutting speed on the material removal rate (MRR) and cutting vo...
Electro Discharge Machining (EDM) is a noticeable machining practice among created unconventional machining procedures for intricate, complex profiles in "hard to machine" materials, similar to heat-treated steels, composites, superalloys, ceramics, composites, carbides, and so on. In EDM, the material expulsion of the cathode is accomplished through precise controlled electric discharge (the s...
Electric Discharge Drill Machine (EDDM) is a spark erosion process to produce micro holes in conductive materials. This process is widely used in aerospace, medical, dental and automobile industries. As for the performance evaluation of the Electric discharge drilling machine it is very necessary to study the process parameters of machine tool. In this research paper a brass rod 2 mm diameter w...
Soltani, N., Vyn, R. J., Van Eerd, L. L., Shropshire, C. and Sikkema, P. H. 2009. Effect of reduced herbicide rates on weed control, environmental impact and profitability of corn. Can. J. Plant Sci. 89: 969 975. A study was conducted over a 3-yr period (2003, 2004, and 2005) to evaluate the effect of reduced herbicide rates 20, 40, 60, 80, and 100% of the manufacturer’s recommended rate (MRR) ...
