Modeling photochemistry in the stratosphere requires solution of the equation of radiative transfer over an extreme range of wavelengths and atmospheric conditions, from transmission through the Schumann-Runge bands of O2 in the mesosphere, to multiple scattering from tropospheric clouds and aerosols. The complexity and range of conditions makes photolysis calculations in 3-D chemical transport...

Zinc transporter (ZnT1) mRNA is differentially expressed in vivo, in weaned pig tissues, and in vitro, in response to additions of zinc sulphate or antibiotics. Summary Preliminary experiments were carried out to evaluate in vivo expression of zinc transporter (ZnT) 1 mRNA in a panel of tissues obtained from weaned pigs and to evaluate in vitro changes in ZnT1 mRNA in a porcine jejunal epithe-l...

Rhizobacteria were isolated from the rhizoplane and rhizosphere of soybean plants from fields in Arkansas and tested for their effect on numbers of soybean cyst nematode (Heterodera glycines). In initial greenhouse tests in heat-treated silt loam soil, 138 of the 201 bacterial isolates tested had no influence on numbers of cysts and eggs + second-stage juveniles (J2) of H. glycines, 36 reduced ...

Many prokaryotic organisms lack an equivalent of RNase E, which plays a key role in mRNA degradation in Escherichia coli. In this paper, we report the purification and identification by mass spectrometry in Bacillus subtilis of two paralogous endoribonucleases, here named RNases J1 and J2, which share functional homologies with RNase E but no sequence similarity. Both enzymes are able to cleave...

Population dynamics of Meloidogyne chitwoodi were studied for 2 years in a commercial potato field and microplots. Annual second-stage juvenile (J2) densities peaked at harvest in mid-fall, declined through the winter, and were lowest in early summer. In the field and in one microplot study, population increase displayed trimodal patterns during the 1984 and 1985 seasons. Overwintering nematode...

Experiments were conducted in the laboratory and greenhouse to determine the effect of raw and anaerobically digested liquid swine manures on the hatch and viability of Heterodera glycines, the soybean cyst nematode. Anaerobic digestion was performed for 15 and 35 days to enrich volatile fatty acids (VFA) and ammonium (NH(4) (+)), respectively. All filtrates of the raw, VFA-enriched, and NH(4) ...

Inactivity in nematodes is often correlated with survival of adverse environments. The non-feeding second-stage juvenile (J2) of Heterodera glycines must survive in a soil environment that may contain numerous toxins. In this report, we show that quiescent J2 of H. glycines survived higher concentrations of both ethanol and the plant-derived compound, allyl isothiocyanate, compared with activel...

The cell wall mannans of two Candida albicans serotype A strains, NIH A-207 and J-1012 (abbreviated as A and J strains, respectively), cultured in yeast extract-Sabouraud liquid medium at pH 2.0, contained neither a phosphate group nor a beta-1,2-linked mannopyranose unit (H. Kobayashi, P. Giummelly, S. Takahashi, M. Ishida, J. Sato, M. Takaku, Y. Nishidate, N. Shibata, Y. Okawa, and S. Suzuki,...

Penelitian ini bertujuan untuk mengetahui waktu proses minimum yang dibutuhkan dalam penyelesaian suatu produk serta metode penjadwalan produksi lebih efisien antara usulan dengan diterapkan di rumah Industri Wahyu, karena kondisi saat berdasarkan First Come Serve (FCFS) menyebabkan adanya keterlambatan produk. Untuk itu, dilakukan penelitian pendekatan deskriptif-kuantitatif menggunakan CDS (C...
