Traditional Total Variation algorithms often ignore the images edge direction. In order to make up for the flaw of the algorithm existing , a novel denosing method based on direction Total Variation is introduced, on the basis of the combination of the gradient magnitude and orientation. Firstly, the pixels are divided into edge regions and non-edge regions by gradient magnitude. Secondly, the ...

Since 1996, when Tararua Wind Power Limited commenced the construction of 48 wind turbines, the number of existing wind turbines on the Ruahine and Tararua ranges has risen dramatically, to 158 in 2006, with more to come from unimplemented, approved resource consents. The companies behind the applications have won plaudits for the development of sustainable energy generation. However, the effec...

Of all the issues surrounding noise emissions from wind farms, the question of the potential for annoyance and adverse effects from low frequency sound is one of the most topical. Anecdotal literature is replete with statements concerning the effects of infrasound and low frequency noise. In this paper we present objective methodologies to measure and assess infrasound and low frequency noise i...

Ipilimumab is an anti-CTLA-4 antibody that is approved for the treatment of metastatic malignant melanoma. Side-effects are mostly immune-mediated and in many cases the lack of specific symptoms leads to delayed diagnosis and treatment of adverse events. We present the case of a female patient who experienced an uncommon combination of adverse reactions while undergoing therapy with ipilimumab ...

background: formaldehyde (h2c = o), is a member of aldehyde family with a simplest organic molecule, used in various industries. the aim of this experimental study was to investigate the effects of simultaneous formaldehyde and noise exposure on hormonal pituitary-gonadal axis in adult male mice. methods: 46 adult male mice were randomly assigned to one control group and three experimental grou...
