Second molar length and body weight are used to test the correlation between tooth size and body size in living Hominoidea. These variates are highly correlated (r= 0.942, p less than 0.001), indicating that tooth size can be used in dentally unspecialized fossil hominoids as one method of predicting the average body weight of species. Based on tooth size, the average body weight of Aegyptopith...

We have carried out an ab initio molecular dynamics study on the sulfur dioxide (SO2) solvation in 1-ethyl-3-methylimidazolium thiocyanate for which we have observed that both cations and anions play an essential role in the solvation of SO2. Whereas, the anions tend to form a thiocyanate- and much less often an isothiocyanate-SO2 adduct, the cations create a "cage" around SO2 with those groups...

China continues its strategy of total emissions control (TEC) or total load control for SO2 in the Tenth Five Years (2001~2005). This paper will analyze the status of SO2 TEC in China during the Ninth Five-Years (1996~2000). Based on the results of the analysis and the theory of divisional air resources, this paper will study the target of total SO2 emissions nationwide and its allocation for d...

BACKGROUND Inhalation of sulphur dioxide (SO2) provokes bronchoconstriction in asthmatic subjects. Cholinergic mechanisms contribute, but other mechanisms remain undefined. The effect of morphine, an opioid agonist, on the cholinergic component of SO2-induced bronchoconstriction was investigated, and the effect of indomethacin, a cyclooxygenase inhibitor, on SO2-induced bronchoconstriction and ...

With the rapid development of the economy, the sulfur dioxide (SO2) emission from China since 2000 is of increasing concern. In this work, we first presented the change of SO2 emission in China since 2000 using a technology-based methodology. Then, we compared the SO2 emission data with a variety of official statistics, ground-based measurements and satellite observations of sulfur related quan...

BACKGROUND This study was conducted to determine the prevalence of a low appendicular skeletal muscle index (ASMI) using three cut-off points (mean ASMI-2SD of a gender-specific young reference group (aged 18-39 years), mean ASMI-1SD of a gender-specific young reference group, and the lower 20 percentile value of a gender-specific older group (aged ≥ 65 years)) in Korean older people and the re...

AR177 is a 17-mer oligonucleotide that has anti-human immunodeficiency virus activity in vitro. The disposition of internally labeled 33P-AR177 was studied after the tail vein injection of single and multiple doses (0.7 mg/kg) to rats. After a single dose, the terminal half-life of AR177 in the blood and plasma was 367 and 271 hr, respectively, significantly longer than values reported for othe...

BACKGROUND In asthmatic subjects bronchoconstriction is induced by inhalation of the common food preservatives sulphur dioxide (SO2) and metabisulphite (MBS). SO2 and MBS challenges share many similarities, but it is not known whether they are equivalent. In this study of subjects with mild clinical asthma equivalence was assessed by comparing SO2 and MBS reactivity by estimating the total dose...

We compared the effect of inhaled NO2 and SO2 on airway tone and airway responsiveness in 14 nonsmoking mild asthmatics (mean +/- SD age 34 +/- 14 yrs; mean +/- SD baseline forced expiratory volume in one second (FEV1), 86 +/- 17% pred). On 3 separate days, 30 min tidal breathing (average minute ventilation 10.6 l.min-1) of either filtered air, 0.25 ppm NO2, or 0.5 ppm SO2 was followed by an is...

As environmental concerns mostly drive the electrification of our economy and corresponding increase in demand for battery storage systems, information about potential impacts different systems is required. However, this kind scarce emerging post-lithium such as magnesium-sulfur (MgS) battery. Therefore, we use life cycle assessment following a cradle-to-gate perspective to quantify cumulative ...
