RE: Simpson Mending Plate for custom made wood truss. I think boo1 pretty welled summed it up. Based on experience my opinion would be that the liability you would be taking on if you try to show that the mend plates work, would be too high.
Isoniazid is often used as a protective treatment to reduce the risk of TB. D100 might be a medicine called doxycycline, which is a drug used to treatment many different things. Please ask your doctor or pharmacist to talk about this. These people will help you understand your medicine and what it is being used for.
Another drug called isoniazid, a derivative of a compound researched earlier by Domagk, was developed in 1952. It also found its place in TB therapy. Thus, in the decade between 1944 and 1954, largely due to the work of Nobel Laureates, three drugs - streptomycin, PAS and isoniazid â became available.
