Discoloration of α-Carbonyl-Free Lignin Model Compounds Under UV Light Exposure

Abstract: A series of α-carbonyl-free lignin model compounds was prepared and adsorbed onto bleached chemical pulp. The rates of discoloration of these materials, under simulated solar light exposure, were established and compared to that of peroxide bleached methylated (alkali and dimethyl sulfate) and nonmethylated chemithermomechanical pulps. Phenolic phenylcoumarone and phenolic stilbenes were found to be the most sensitive chromophores under UV irradiation, both inducing a strong yellowing. Also, monophenolic biphenyl and biphenylmethane entities were shown to be prone to discolouration in contrast to the biphenolic and dimethylated ones. Moreover, the catechol structures which are known to be easily oxidizable into ortho quinones, display significant yellowing only when their absorption spectra are shifted above 300 nm where the light source emits. The behaviour of the phenolic stilbenes and the biphenyl catechol is reminiscent of the behaviour of CTMP. This indicates the possible involvement of such...

The effects of reducing frequency of negative thoughts on the mood of depressed patients — tests of a cognitive model of depression

Abstract: Cognitive theories of depression propose that depressed mood is caused by depressing cognitions (negative thoughts). In two studies of depressed patients, presentation of external information at a high rate was used to reduce the frequency of negative thoughts, and the subsequent effect on depressed mood examined. Single-case designs were employed in both studies. In the first study, significant reduction in negative thoughts and depressed mood was achieved in each of two selected patients. In the second study, the same procedure produced reduction in negative thoughts which was individually significant for seven of 13 unselected depressed patients, and also significant for the 13 patients as a group. However, this led to little improvement in depressed mood. This appeared to be due to the small extent of thought reduction achieved. Reduction in negative thought frequency correlated significantly with score on the Newcastle diagnosis scale, being greater for neurotic compared to endogenous depression. Mean depressed mood and mean negative thought frequency were significantly positively correlated across subjects.

The meaning of reporting forgetfulness: a cross-sectional study of adults in the English 2007 Adult Psychiatric Morbidity Survey

Abstract: Method: we analysed data from the English 2007 Adult Psychiatric Morbidity Survey, representative of people in private households. Participants were asked whether they had noticed problems with forgetting in the last month, or forgotten anything important in the last week; and completed the modified Telephone Interview for Cognitive Status.Results: of those contacted, 7,461 (57%) participated. After excluding participants screening positive for dementia, 2,168 (31.7%) reported forgetfulness in the last month, while 449 (6.4%) had forgotten something important in the last week. Reporting forgetfulness was not associated with age. In a multivariate analysis including cognition and age, the only significant associates of reporting forgetfulness were anxiety, depressive and somatic symptoms.Conclusions: our hypothesis that subjective forgetfulness prevalence would rise with age in a non-demented population was not supported. Although subjective forgetfulness can be an early symptom of future or mild dementia, it is common and non-specific and-at population level-is more likely to be related to mood than to be an early symptom of dementia. Asking those presenting with subjective forgetfulness additional questions about memory and functional decline and objective forgetfulness is likely to help clinicians to detect those at risk of dementia.

The UK Landfill Tax : an analysis of its contribution to sustainable waste management

Abstract: The UK Government in October 1996 introduced a Landfill Tax to ensure that landfill waste disposal is properly priced so as to reflect its environmental cost and to help promote a more sustainable approach to waste management in which less waste is produced, reused or recycled. The UK Customs and Excise have recently reviewed the tax and the report indicates that there has been a modest reduction in waste going to landfill by industry but not households. It is submitted that for there to be a significant move towards a more sustainable approach to waste management to meet the targets set in the National Strategy the tax should be higher and the money raised by the tax should be invested to make alternatives to landfill cheaper and more readily available. It is also submitted that the Tax Credit Scheme, introduced as a means of enabling some of the tax to be invested to promote better waste management, is inadequately funded and the money is inappropriately focused. Following an examination of the projects and contributions made under the Scheme it is found that most of the contributions are not made towards projects which will fulfil the UK Government's perceived purposes. It is further submitted that there needs to be a more rational approach to waste management and legislation in Philadelphia forms a good case study of such an approach

Comparative analysis of cervical arthroplasty using mobi-c(r) and anterior cervical discectomy and fusion using the solis(r) -cage.

Abstract: Objective Although anterior cervical discectomy and fusion (ACDF) is the standard treatment for degenerative cervical disc disease, concerns regarding adjacent level degeneration and loss of motion have suggested that arthroplasty may be a better alternative. We have compared clinical and radiological results in patients with cervical disc herniations treated with arthroplasty and ACDF.
