Abstract

STUDI APLIKASI METODE POTENSIOMETRI PADA PENENTUAN KANDUNGAN KARBON ORGANIK TOTAL TANAH  The result of patrol observation of dwarf novae at the Bosscha Observatory are presented. The images of the region of four dwarf novae, MM Scorpii, V2051 Ophiuci, V391 Scuti and V3462 Sagitarii could be taken. MM Scorpii and V391 Scuti were not detectable implying quiescence state. The eclipsing SU UMa type dwarf nova, V2051 Ophiuci was observed during its outburst. Brightness measurement using aperture photometry method yields (15.2 ± 0.3) mag. V3462 Sagitarii were also detectable and the brightness (15.3 ± 0.6) mag were derived. Therefore this star is suspected in its outburst state during the observation.

Abstract

The effect of PGF2α on the fertility of male Wistar rat (Rattus norvegicus) has been investigated . Sexually mature male rats with a body weight of 200 to 300 g were used . Sperm numbers and quality, and mating ability, were observed after rats were subcutaneously injected with 1.5 ; 2.0 and 3.0 mg/kg body weight of PGF2α dissolved in 0.4 ml saline solution daily for 11 consecutive days for the treatment groups , respectively. Contraction of caudal epididymis and vas defferens were recorded using myograph and physiograph, whereas the concentration of PGF2α was 0.4 and 0.6 mg/ml dissolved in Tyrode. The result showed that motility and number of normal as well as abnormal sperm decreased in conjuction with the increasing dosage of PGF2α. The contraction of organs which occurred when solution was added, showed that PGF2α increased the tonus tensions of caudal epididymis as well as vas deferens. There were no differences in mating ability of the treated rats compared to the control rats, while the fertility index of treated rats was significantly (p

Abstract

New 11-(3-indolyl)benzo[b]carbazoles (11 and 13) can be synthesised readily in good yields from the reaction of simple indoles (8, 12) and o-phthaldialdehid (7) in the presence of phosphoryl chloride.

Abstract

STUDI APLIKASI METODE POTENSIOMETRI PADA PENENTUAN KANDUNGAN KARBON ORGANIK TOTAL TANAH  A new indolo-cyclotriveratrylene: 1,4,7-trihydrocyclononano[2,3-b: 5,6-b: 8,9-b:]tri-1-benzylindole (21) was synthesized in good yield from the acid catalysed dehydration of 1-benzyl-3-hydroxymethylindole (20). The structure of the new indole cyclic trimer (21) was established by spectroscopy and microanalysis. The synthesis of the alcohol (20) was performed in two steps by alkylation of indole-3-carbaldehyde (18) followed by reduction with sodium borohydride.
