The impact of increasing the incinerator ash content on landfill site biostabilisation
No full textThe results of ash characterisation showed that the total carbon (TC) and total nitrogen (TN) in different sieved particle sizes increased as the particle size decreased. The average total content of the heavy metals Cu, Cd, Pb, Zn, Ni and Cr was 7786, 29, 994, 4006, 224 and 226 μgg-1 respectively. The leaching results of 10 g bottom ash mixed with 500 ml distilled water using tumbling and reciprocating shaking showed that the leaching concentration was in the range of 0~11 μgg-1. Leaching from the ash was greater at the extremes of pH and temperatures these having the greatest effect on leachate concentrations of Zn, Pb, and Cu. An inhibitory effect of heavy metals was shown at a 50% levels for Zn, Cu and Ni of 650mg Znl-1 dry solid sludge, 360 mg Cul-1 and 40 mg Cug-1 dry solid sludge and 380 mg Nil-1 and 39 mg Nig-1 dry solid sludge respectively. Bottom ash showed potential adsorption capacity for organic matter which was influenced by ash concentration, pH, temperature and particle size. the adsorption capacity increased as the ash concentration, pH, temperature, and particle size decreased. The anaerobic co-digestion of bottom ash and a simulated domestic refuse showed the beneficial effect of bottom ash addition. These studies were conducted in laboratory scale anaerobic digesters with a retention time of 20 days. Four reactors were used, two of these (controls) had no ash addition whilst the other two had ash added with the batch fed refuse simulant in a ration of 25/100 and 50/100 respectively.</p
The relationship between co-authorship, currency of references and author self-citations
No full textThis paper attempts to identify the relationship between co-authorship and the currency of the references and author self-citations in the key journals of environmental engineering. The results show that the self-citation rate of co-authored articles is higher than in single-authored articles. A statistically significant correlation is identified between the numbers of co-authors, the rate of author self-citing and the author self-cited; though it was a low correlation. The value of coefficient correlation between the number of co-authors and the author self-citing rate is slightly higher than that between the number of co-authors and the author self-cited rate, which indicates that the number of co-authors hold a stronger correlation with the self-citing rate than the self-cited rate. Meanwhile, self-citing references are found to be more up-to-date than references to others. The range of publication years of self-citing references is smaller than that of references to others, indicating that researchers tend to preferentially cite their own recent works. There is no significant difference in the latest references between self-citing references and the references to others. It might result from electronic journals that provide an easy access to the most current publications.補正完畢國外SSCIY紙本電子版HU

Probing the effect of author self-citations on h index: A case study of environmental engineering
No full textThis study evaluates the impact of author self-citations on h index by exploring 583 authors whose works appear in key periodicals in environmental engineering. The findings show that authors’ h values have high correlation with authors’ article number, total cited count, and their rankings. There is also a high correlation with h index values and rankings of h values. The study indicates that selfcitations have little impact on the values of h index and the h index rankings, whether or not articles with authors’ self-citation are included. Further investigations reveal that, for authors with high values in h index, the two h index values are both highly correlated and with significant difference either with self-citations or without. A similar pattern is seen in authors with low h values. The results suggest that there is no need to deliberately exclude self-citations in analysing or evaluating research performance in environmental engineering.國外SSCIY電子版紙本GB
A Comparison of Three Major Academic Rankings for World Universities: From a Research Evaluation Perspective
No full textForgotten features of head zones and their relation to diagnostically relevant acupuncture points
Full text linkIn the 1890s Sir Henry Head discovered certain areas of the skin that develop tenderness (allodynia) in the course of visceral disease. These areas were later termed ‘Head zones’. In addition, he also emphasized the existence of specific points within these zones, that he called ‘maximum points’, a finding that seems to be almost forgotten today. We hypothesized that two important groups of acupuncture points, the diagnostically relevant Mu and Shu points, spatially and functionally coincide with these maximum points to a large extent. A comparison of Head's papers with the Huang Di Neijing (Yellow Thearch's Inner Classic) and the Zhen Jiu Jia Yi Jing (Systematic Classic of Acupuncture and Moxibustion), two of the oldest still extant Chinese sources on acupuncture, revealed astonishing parallels between the two concepts regarding both point locations and functional aspects. These findings suggest that the Chinese discovery of viscerocutaneous reflexes preceded the discovery in the West by more than 2000 years. Furthermore, the fact that Chinese medicine uses Mu and Shu points not only diagnostically but also therapeutically may give us new insights into the underlying mechanisms of acupuncture
