How to use Ortho in a sentence
Glyphosate-based herbicides like Roundup and triclopyr-based herbicides like Ortho Brush-B-Gon will kill poison plants, but they can also take out any other surrounding foliage they come into contact with.
The birth control patch, sold under the brand name Ortho Evra, is made by Ortho-McNeil Pharmaceutical, Inc. It contains progestin and estrogen, which are the same hormones found in birth control pills.
Information about side effects is available on the Ortho Evra web site.
In 2002, birth control pill manufacturer Ortho teamed up with fashion designer Nicole Miller to create a beautiful alternative to boring old plastic birth control compacts.
Other fashionable Ortho designs include Fuchsia Daisy, Expressions, Onyx, and Lapis.Advertisement
Unfortunately, these beautiful birth control cases are no longer available from Ortho.
However, Ortho is offering a nice alternative.
Birth control pills such as Errin, Ortho Micronor, and Ovrette contain no estrogen, only progestin.
Women who suffer from acne might find the best birth control pills to be Yaz, Estrostep, and Ortho Tri-Cyclen.
This birth control pill category features several well-known brands, including Alesse, Ortho Tri-Cyclen, Ortho-Novum, Yaz and Yasmin.Advertisement
Acne sufferers may want to choose a pill that has a higher estrogen amount, such as Yasmin, Yaz, or Ortho Tri-Cyclen.
He assumed that if we have one atom 1 It is now established that ortho compounds do exist in isomeric forms, instances being provided by chlor-, brom-, and amino-toluene, chlorphenol, and chloraniline; but arguments, e.g.
The diazo group takes up the para position with regard to the hydroxyl group, and if this be prevented it then goes into the ortho position.
Bamberger (Ber., 1900, 33, p. 3189) simultaneously with the para compound, from which it may be separated by distillation in a current of steam, the ortho compound passing over with the steam.
Meyer (Ber., 18 94, 2 7, p. 510 et seq.) showed that in benzenoid compounds ortho-substituents exert a great hindering effect on the esterification of alcohols by acids in the presence of hydrochloric acid, this hindering being particularly marked when two substituents are present in the ortho positions to the carboxyl group. In such a case the ester is best prepared by the action of an alkyl halide on the silver salt of the acid, and when once prepared, can only be hydrolysed with great difficulty.Advertisement
Many ortho and, para-compounds of the aromatic series (for example, the brom-phenols, benzene para-disulphonic acid) also yield resorcin on fusion with caustic potash.
The mixture can be separated by shaking with sulphuric acid, whereupon the ortho and meta forms are converted into soluble sulphonic acids, the para form being soluble only in concentrated acid; the ortho and meta acids may be separated by crystallization of their salts or sulphonamides.
Decker (Ber., 9 5, 38, p. 1144) has found that many ortho substituted quinolines will not combine with methyl iodide owing to steric hindrance, but the difficulty can be overcome in most cases by using methyl sulphate and heating the reaction components to ioo C. for half an hour.
On nitration it gives orthoand para-nitrotoluenes - which on reduction yield the valuable toluidines, C6H4(CH3)(NH2) - and on sulphonation the parasulphonic acid is formed with a little of the ortho acid.
Somewhat later, they found that it could be prepared from diazobenzene imide, provided a nitro group were present in the ortho or para position to the diazo group. The para-nitro compound is dropped slowly into a cold solution of one part of caustic potash in ten parts of absolute alcohol; the solution becomes dark red in colour and is then warmed for two days on the water bath.Advertisement
Write down the possible nuclear spin states for H 2 and hence calculate the nuclear spin degeneracy of ortho and para-H 2.
Phosphorus can exist as poly, ortho or organic phosphorus can exist as poly, ortho or organic phosphorus.
Systems free of this aberration are called " ortho scopic " (ipgos, right, r ' 0-K071-6 1/, to look) .
In this month's interview, we spoke with Sabrina Zohar, the "It Girl" for Ortho Tri-Cyclen Lo and a fundraiser for the Invisible Children Organization in Uganda.
I learned about the It Girl campaign after I was prescribed to Ortho Tri-Cyclen Lo.Advertisement
