The Mo(Ⅴ) and W(Ⅵ) complexes of (NH3CH2- CH2NH2)3[Mo(Ⅴ)O2(OC6H4O)2] (1), (NH3CH2CH2NH2)2.5 [Mo(Ⅴ) 0.5W(Ⅵ)0.5O2(OC6H4O)2] (2) and (NH3CH2CH2NH2)2- [W(Ⅵ)O2(OC6H4O)2] (3) were synthesized by choosing cate-chol liga...
Considerable progresses in the sedimentologic studies of the anastomosing river models have been made in recent years. There are now many modern and ancient examples such as those described by Smith, Rust et al. Flore...
Using acetylcholinesterase (AChE) histochemical technique, Shute and Lewis (1960) traced nervus intermedius, which innervated submandibular gland and sublingual gland, to two strongly AChE positive nuclei situated res...
Investigation of metabolic changes of host cells in tissue culture caused by Rickettsia tsutsugamushi helps to elucidate the pathogenesis and mechanism of immunity in scrub typhus. We used the histochemical methods fo...
