ABSTRACT No-till planting and the use of organomineral fertilizers are crop management practices that increase soil organic matter, thereby mitigating leaching cycling a considerable amount nutrients, with potential to improve yield. This study aimed assess agronomic performance cabbage grown under no-till system, using different cover crops phosphorus sources. A randomized block design was use...

Light states relevant to the $\chi^{(2)}$ comb generation in optical microresonators possess typically dual backgrounds for coupled first-harmonic (FH) and second-harmonic (SH) envelopes. Stability and/or instability of these is crucial realization stable combs also an efficient SH generation. We explore properties their cases FH pumping resonator. In contrast parameteric oscillation, controlle...

Abstract Methyl mercaptan (CH 3 SH) is one of the S-bearing organic compounds found in interstellar medium (ISM). In this study, we investigated surface reactions solid CH SH with H atoms on amorphous water using experimental and computational methods to examine their physicochemical behavior ISM. Consequently, primary product was discovered be 4 . As studies show that dominant reaction pathway...

Colonic bacteria liberate large quantities of the highly toxic gases hydrogen sulfide (H(2)S) and methanethiol (CH(3)SH). The colonic mucosa presumably has an efficient means of detoxifying these compounds, which is thought to occur through methylation of H(2)S to CH(3)SH and CH(3)SH to dimethylsulfide (CH(3)SCH(3)). We investigated this detoxification pathway by incubating rat cecal mucosal ho...

Despite their sympathetic neuroblast origin, highly malignant neuroblastoma tumors and derived cell lines have no or low expression of the neurotrophin receptor genes, trkA and trkC. Expression of exogenous trkA in neuroblastoma cells restores their ability to differentiate in response to nerve growth factor (NGF). Here we show that stable expression of trkC in SH-SY5Y neuroblastoma cells resul...

OBJECTIVE Many states and local communities have enacted social host (SH) laws to reduce underage drinking in private settings. However, little is known about whether such laws are effective. This study examined relationships between city SH laws and underage drinking in general and at parties in private settings. METHOD SH policy data were collected for 50 California cities in 2009, and SH p...

Sinomenine hydrochloride (SH) has been investigated for its anti-tumor growth effect. We have previously reported that SH inhibited breast cancer cell proliferation via MAPKs signaling. However, whether SH could inhibit tumor metastasis has not been fully explored. In this study, we found that SH suppressed the metastasis potential of breast cancer cells. The wound healing and transwell assays ...

1. 1 cc. of 0.001 M ferricyanide, tetrathionate, or p-chloromercuribenzoate is required to abolish the SH groups of 10 mg. of denatured egg albumin in guanidine hydrochloride or Duponol PC solution. Both the nitroprusside test and the ferricyanide reduction test are used to show that the SH groups have been abolished. 2. 1 cc. of 0.001 M ferrocyanide is formed when ferricyanide is added to 10 m...

Although the function of sleep is hotly debated, one thing is clear—we, and most other animals, cannot do without it. In a new study, Yokogawa et al. describe how zebrafi sh sleep, fi nding both striking similarities to mammalian sleep and its regulation and intriguing differences. How can you tell when a zebrafi sh is asleep? According to Yokogawa et al., it stops swimming (for at least six se...
