One of the ways to increase production for aquaculture is through cultivation monosexuals by ensuring genital reversal from which energy reproduction diverted towards growth. Masculinization has been identified as one most prominent techniques, where sex development was directed female male. This approach only altered phenotype and not genotype. The red claw crayfish (Cherax quadricarinatus) a ...

Exhaust emissions from ships have garnered significant attention because of their impact on global climate change, deterioration air quality, and potential risks to human health. Consequently, it is necessary urgent quantify the gaseous particulate emission factors (EFs) in a local area. In order supplement native EF profile data, an inland cargo ship China was selected for measuring particle p...

The title compound, C20H28O2, is a steroid with strong anabolic properties. The present solvent-free form crystallizes with two mol-ecules per asymmetric unit. In the crystal, both mol-ecules are involved in the formation of O-H⋯O hydrogen-bonded chains which extend along the b-axis direction.

The title compound, C(19)H(28)O(3), the fungal-transformed metabolite of the steroid methyl-oestrenol contains four fused rings A, B, C and D. Ring A adopts a half-chair and the trans-fused rings B and C adopt chair confirmations; the five-membered D ring is folded like an envelope. In the crystal, adjacent mol-ecules are linked by O-H⋯O(carbon-yl) and O-H⋯O(hy-droxy) hydrogen bonds into a laye...
