The effects of natural traditional energy sources which is called biomass, mainly cowdung, on pulmonary function was investigated. In rural regions of Sivas City, pulmonary function tests of 112 cow-dung users and 153 modern energy source users were compared. When comparing the mean values of spirometric measurements of two groups' males and females seperately, all the spirometric parameters of...

0.0 Introduction Anong, a Tibeto-Burman language of Yunnan, is in its last generation—in 1999, there were 62 fluent speakers left, all over 50. The descriptive material on Anong is quite limited; what there is all comes from the work of Sun Hongkai, particularly 1988, 1999a, and a preliminary, but still useful wordlist (Sun ms.); a little additional data can be found in Sun Hongkai 1999b and Su...

The residue levels of selected fluoroquinolones, sulfonamides and tetracyclines in 143 animal dung samples collected in 2007 from large-scale livestock and poultry feedlots in 8 provinces were determined by using ultrasonic extraction and liquid chromatography. Recoveries from spiked pig dung samples (spike level=1mg/kg) ranged from 73.9 to 102.0% for fluoroquinolones, from 81.6 to 92.3% for su...

Research on dung beetles is uncovering surprising insights into both the history of this ancient family of insects and the value of the ecological services many species provide. For one, some dung beetles are far older than scientists realized. An Australian and Czech research team found molecular evidence that the scarab beetle subfamily Scarabaeinae evolved 115 million to 120 million years ag...

Southeast Asia is a hotspot of imperiled biodiversity, owing to extensive logging and forest conversion to oil palm agriculture. The degraded forests that remain after multiple rounds of intensive logging are often assumed to be of little conservation value; consequently, there has been no concerted effort to prevent them from being converted to oil palm. However, no study has quantified the bi...

Abstract The need to investigate an eco-friendly and renewable alternative energy source has been prompted by issues relating the depletion of conventional fuel resources. One best green alternatives is bioenergy, which also encourages sustainable use agricultural waste. This study was carried out utilization pineapple peels for bio-briquette production. aimed determine characterization using d...

To escape competition at the dung pile, a ball-rolling dung beetle forms a piece of dung into a ball and rolls it away. To ensure their efficient escape from the dung pile, beetles rely on a 'celestial compass' to move along a straight path. Here, we analyzed the reliability of different skylight cues for this compass and found that dung beetles rely not only on the sun but also on the skylight...

The effects of sheep urine and dung patches on methane (CH4) and carbon dioxide (CO2) fluxes were investigated during the summer-autumn in 2010, to evaluate their contribution to climate change in a desert grassland in Inner Mongolia, China. Results indicate that the cumulative CH4 emissions for dung patches, urine patches and control plots were - -0.076, -0.084, and -0.114 g/m(2) and these wer...

Grazing extensification and intensification are among the main problems affecting European grasslands. We analyze the impact of grazing intensity (low and moderate) and the use of veterinary medical products (VMPs) on the dung beetle community in the province of Pesaro-Urbino (Italy). Grazing intensity is a key factor in explaining the diversity of dung beetles. In the case of the alpha diversi...

The endemic dung beetle subtribe Helictopleurina has 65 species mostly in wet forests in eastern Madagascar. There are no extant native ungulates in Madagascar, but three Helictopleurus species have shifted to the introduced cattle dung in open habitats in the past 1500 years. Helictopleurus neoamplicollis and Helictopleurus marsyas exhibit very limited cytochrome oxidase subunit 1 haplotype di...
