Swamp Barges operate in very shallow water (less than 20 ft). They can be towed onto location and are then ballasted so that they sit on bottom . The drilling unit is mounted onto the barge. This type of unit is popular in the swamp areas of Nigeria. [Pg.32]

If one or more clusters of single wells are required then an Underwater Manifold System can be deployed and used as a subsea focal point to connect each well. The subsea trees sit on the seabed around the main manifold (compared to the template). [Pg.270]

Detection of this particle accumulation has so far been done visually. To make the particles more easily visible, they have been chemically treated in order to make them light up or flouresce when struck by an ultraviolet light. The operator sits in a darkened room in which the test pieces are illuminated by ultraviolet light. Cracks show up very clearly and in principle this method of inspection is acceptable. Despite the effiency of this method it is well known that a large number of defective pieces pass this test. Why is it so ... [Pg.639]

Let us focus our adention for the moment on a small volume in space, dr, and on particles in the volume with a given velocity v. Let us sit on such a particle and ask if it might collide in time t with another particle whose velocity is v, say. Taking the effective diameter of each particle to be a, as described above, we see... [Pg.669]

However, most impurities and defects are Jalm-Teller unstable at high-symmetry sites or/and react covalently with the host crystal much more strongly than interstitial copper. The latter is obviously the case for substitutional impurities, but also for interstitials such as O (which sits at a relaxed, puckered bond-centred site in Si), H (which bridges a host atom-host atom bond in many semiconductors) or the self-interstitial (which often fonns more exotic stmctures such as the split-(l lO) configuration). Such point defects migrate by breaking and re-fonning bonds with their host, and phonons play an important role in such processes. [Pg.2888]

The next step in iin proving a basis set could be to go to triple zeta, quadruple zeta, etc. Ifone goes in this direction rather than adding functions of higher angular quantum number, the basis set would not be well balanced. With a large number of s and p functions only, one finds, for example, that the equilibrium geometry of am monia actually becomes planar.

A similar apparatus, but without the advantage of the central ground joint is marketed under the name Buechner stable filter f (Fig. 11,35, 2, a) one method of use is shown in Fig. II, 35, 2, b. The Buechner stable filter is made of porcelain the filtrate is drawn off through a vacuum chamber below the perforated plate, the whole apparatus is supported by a cylindrical base, and sits firmly on the bench. The sizes of perforated plate available are 56, 91, 111, 126, 186, 241 and 308 mm. diameter respectively, and it would appear that these will... [Pg.134]

For each M , Ml combination for which one can write down only one product function (i.e., in the non-equivalent angular momentum situation, for each case where only one product function sits at a given box row and column point), that product function itself is one of the desired states. For the p2 example, the piapoot and piap.ia (as well as their four other Ml and Ms "mirror images") are members of the 3p level (since they have Ms = 1) and IpiapiPI and its Ml mirror image are members of the level (since they have Ml... [Pg.254]

So now that we have all the reagents out of the way let s see how the reaction proceeds. There s the clear- yellow "safrole" sitting in the bottom if the flask and the clear saturated KOH solution is dumped in. The solution is heated to reflux etc. and yes, some brown byproducts and destruction artifacts will appear. Especially if the safrole is not pure. These byproducts should be expected to some extent because concentrated basic (OH) solutions can be as nasty as concentrated acidic solutions. One is mindful that KOH is less intrusive towards the delicate methylenedioxy ring structure of the safrole/isosafrole molecule. [Pg.40]

The chemist can try to separate the two isomers by careful fractional distillation but it will be next to impossible to do because both the cis and the trans have practically the same boiling point. There are a few things that the chemist can do or hope for to get rid of that cis isomer. The cis configuration is less stable than the trans and may switch over to the trans configuration with a little help. The chemist can gently heat the isosafrole oil to about 150°C for an hour or so. She can also try the same heating except have the oil mixed with some acetic acid. Also, the isosafrole can be fractionally distilled to ultra purity and then be allowed to simply sit for a couple of days. Trans isosafrole may spontaneously crystalize out while the cis form remains as an oil. They can then be separated by filtration. [Pg.44]

B. Big secret..Quack , Use approximately a total of 600 ml (twice the amount prescribed) for the three extractions. Don t quack at me...its starting fluid. It s cheap Quack Here it is Let the first extraction sit for several hours (or overnight) and the seperation will be VERY clean. However, there will still be an emulsion present in the ether layer. Now, the Quackload of product will be in the first extraction, so the emulsion and settling of the following two will be much quacker (faster). Combine ALL three ether extracts and note that there will be a little water that will separate out from them. [Pg.91]

The catalyst needed is called sodium cyanoborohydride (NaBHaCN). It is not very common but there are few places that still sell it. It is very prone to take up water out of the air so the chemist makes sure that she doesn t leave it sitting out ail night. The method is simplicity itself. [Pg.98]

Russian articles make some outrageous claims and this one is no different [43], These mothers claim that piperonal or benzaldehyde will react with nitroethane by sitting in the dark at 10°C with only a couple of drops of ethylenediamine. Almost 100% yield no less Strike has never tried this nor does Strike fall for Russian science, but if anyone is interested... [Pg.130]
