In this paper, we give a finite number of defining relations satisfied by a finite number of generators for the elliptic Lie algebras and superalgebras gR with rank ≥ 2. Here the R’s denote the reduced and non-reduced elliptic root systems with rank ≥ 2. We also show that if L is an extended affine Lie algebra (EALA) whose non-isotropic roots form the R, then there exists a natural homomorphism...

A new enzymatic spectrophotometric assay for the determination of lactulose in milk samples was developed. This method entailed the use of b-galactosidase which hydrolyses lactulose giving fructose and galactose, and fructose dehydrogenase which reacts with fructose in presence of a tetrazolium salt (MTT), giving a coloured compound which can be detected spectrophotometrically at 570 nm. The as...

The sucrose hydrolysis and the preference of consumption of glucose instead of fructose were investigated for the production of 5-hydroxy-2-hydroxymethyl-γ-pyrone (HHMP) in the presence of Aspergillus flavus IOC 3974 cultivated in liquid Czapeck medium. Standardized 0.5g of pellets were transferred as inoculum into twelve conical flasks of 250 ml containing 100 ml of medium with different sucro...

Homogeneous preparations of thioredoxin-linked fructose-l,6-bisphosphatase and sedoheptulose-l,7-bisphosphatase were prepared from leaves of corn (Zea mays), a classical C4 plant. Fructose-1,6-bisphosphatase had a molecular weight of 184,000 and consisted of four apparently identical subunits of M, = 46,000. Sedoheptulose-1,7-bisphosphatase, by contrast, was composed of two identical subunits o...

Penelitian ini dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Jabal Ghafur Kabupaten Pidie, bertujuan untuk mengetahui pengaruh aplikasi pupuk mamigrow dan uji beberapa jenis media tanam terhadap pertumbuhan bibit kopi. Faktor yang diteliti adalah: (J), tiga taraf yaitu: J1= tanah+sekam padi (4:1), J2= tanah+serbuk gergaji J3= tanah+pupuk kandang(4:1). (M), empat M0= 0 gr/liter ...

A new method for rearing honey bees, Apis mellifera L. (Hymenoptera: Apidae), in vitro was developed and the effects of sugar concentrations on survival and development were studied. Seven different glucose (G) and fructose (F) compositions (0%G+0%F, 3%G+3%F, 6%G+6%F, 12%G+12%F, 0%G+12%F, 12%G+0%F, and 4%G+8%F) were tested. Larvae were able to grow to the post defecation stage without addition ...

background hepatocytes are used as an in vitro model to evaluate drug metabolism. human hepatocyte transplant has been considered as the temporary treatment of acute liver failure. optimization freezing methods is very important to preserve both cell viability and function which are achieved by cryopreservation mostly always. objectives the present study aimed to investigate the cryoprotective ...
