Even if liberals will be hard-pressed to oust Cruz in a state that hasn't elected a Democrat statewide in decades -- let alone in a non-presidential year -- a Republican primary challenge could very well roughen up the senator and force him to use his political capital, time and money much differently.
To assure adherence of the dipcoat to the wax, prewetting in a suitable agent to remove mold parting lubricant and microscopically roughen the wax surface may be necessary.
There are also numerous very fine, slightly prominent growth lines which tend to roughen the spiral sculpture. The aperture is short and wide. The outer lip (defective) is thin and simple. The body, with the sculpture erased, is polished, milky white.
The inner lip is complete, applied, glazed, thin, thickened at the back to meet the margin of the sinus. The columella is nearly straight. The thin spirals number seven in the penultimate whorl and twenty in the body whorl. Faint accremental striae minutely roughen the sculpture.
After the fleece is removed, it is cleaned by hand, removing vegetation and other foreign matter, and then dehaired. Dehairing is the removal of intermediate hairs (greater than in diameter). Dehairing is accomplished by carding as one would cashmere. Mechanical carding can cause breakage and weaken and roughen the qiviut.

These water patterns are outlined by sunglint (light reflecting off of the water surface back towards the camera on board the International Space Station). The sunglint patterns are due to wind and currents, which roughen the water surface and enhance reflection, and surfactants that decrease the surface tension and roughness, resulting in regions of dark, smooth water.
Papaya ringspot virus is a well-known virus within plants in Florida. The first signs of the virus are yellowing and vein-clearing of younger leaves, as well as mottling yellow leaves. Infected leaves may obtain blisters, roughen, or narrow, with blades sticking upwards from the middle of the leaves. The petioles and stems may develop dark green greasy streaks and in time become shorter.
From the distinct suture the surface slopes flatly to the subangular periphery, the rest of the whorl is rounded. The spiral sculpture consists of uniform fine threads with narrower interspaces over the whole surface. The axial sculpture consists of (on the body whorl 15) narrow rather sharp ribs with much wider interspaces, obsolete behind the shoulder and on the base. There are also fine incremental lines which roughen the spiral threads.
Balls may be given features which roughen the surface and extend the hit or throw distance. Roughening causes the boundary layer to become turbulent and remain attached farther round the back before breaking away with a smaller wake than would otherwise be the case. Balls may be struck in different ways to give them spin which makes them follow a curved path. The spin causes boundary layer separation to be biased to one side which produces a side force.
Two-shot molding is an injection molding process using two different resins and only one of the two resins is platable. Typically the platable substrate is ABS and the non- platable substrate is polycarbonate. In a two shot component, these are then submitted to an electroless plating process where the butadiene is used to chemically roughen the surface and allow adhesion of a copper primary layer. The plating chemistry can be controlled to prevent the roughening of the polycarbonate portions of the component.
After which care must be taken not to touch and/or dirty the surface prior to spraying. The three methods used to roughen up the substrate surface are abrasive blasting, machining and bond coating. Cleaning occurs only after the roughening of the surface except for when a bond coating is used; the surface must be cleaned before and possibly after this process too. Application of the detonation spray coating should be performed as soon as possible after a substrates surface has been prepared.
"Anne Sexton (1988) Steven E. Colburn, University of Michigan Press, 1988 p438 Sexton's work towards the end of the sixties has been criticized as "preening, lazy and flip" by otherwise respectful critics. Some critics regard her dependence on alcohol as compromising her last work. However, other critics see Sexton as a poet whose writing matured over time. "Starting as a relatively conventional writer, she learned to roughen up her line...to use as an instrument against the 'politesse' of language, politics, religion [and] sex.
The branches could be bent and shaped using various forms of bamboo scaffolding, twisted lead strips, and iron or brass wire to hold them in place; they could also be cut, burnt, or grafted. The bark was sometimes lacerated at places or smeared with sugary substance to induce termites ("white ants") to roughen it or even to eat the similarly sweetened heartwood. Rocks with moss or lichens were also a frequent feature of these compositions. The earliest known photograph from China which included penjing was made c.
The Dayton Daily News wrote "Veteran Bill Gradison is being perfunctorily challenged by Thomas Chandler, who admits to having happily voted for Rep. Gradison in the past. The Democrats wanted to put somebody on the ticket." Chandler supported raising taxes to lower the budget deficit, was pro-choice, and opposed the North American Free Trade Agreement (NAFTA) and school vouchers. On November 3, Chandler lost to Gradison, a congressman since 1975, by a vote of 75,924 to 177,720, with write-in candidate Emily Roughen Wood receiving seven votes.
For some iron kitchen utensils, water is a particular problem, since it is very difficult to dry them fully. In particular, iron egg-beaters or ice cream freezers are tricky to dry, and the consequent rust if left wet will roughen them and possibly clog them completely. When storing iron utensils for long periods, van Rensselaer recommended coating them in non-salted (since salt is also an ionic compound) fat or paraffin. Iron utensils have little problem with high cooking temperatures, are simple to clean as they become smooth with long use, are durable and comparatively strong (i.e.
Many objects are made with polypropylene precisely because it is resilient and resistant to most solvents and glues. Also, there are very few glues available specifically for gluing PP. However, solid PP objects not subject to undue flexing can be satisfactorily joined with a two-part epoxy glue or using hot-glue guns. Preparation is important and it is often helpful to roughen the surface with a file, emery paper or other abrasive material to provide better anchorage for the glue. Also it is recommended to clean with mineral spirits or similar alcohol prior to gluing to remove any oils or other contamination.
Using a file to abrade the surfaceIn general, abrasion is superior to other methods of surface preparations due to the fact that it is simple to perform, and it does not produce a significant amount of waste. To prepare the adherend for bonding, the surface can be sanded or grit blasted with an abrasive material to roughen the surface and remove any loose material. Rough surfaces produce stronger bonds because they have an increased surface area for the adhesive to bond to as compared to a relatively smooth surface. In addition, roughening the surface will also increase mechanical interlocking.
If it were produced without any additives, the surface of the film would be so smooth that layers would adhere strongly to one another when the film is wound up, similar to the sticking of clean glass plates when stacked. To make handling possible, microscopic inert inorganic particles are usually embedded in the PET to roughen the surface of the film such as silicon dioxide. Biaxially oriented PET film can be metallized by vapor deposition of a thin film of evaporated aluminium, gold, or other metal onto it. The result is much less permeable to gases (important in food packaging) and reflects up to 99% of light, including much of the infrared spectrum.
Some triathlon wetsuits go further, and use rubber-molding and texturing methods to roughen up the surface of the suit on the forearms, to increase forward drag and help pull the swimmer forwards through the water. Extremely thin 1 mm neoprene is also often used in the under-arm area, to decrease stretch resistance and reduce strain on the swimmer when they extend their arms out over their head. Wetsuits used for caving are often single- backed with a textured surface known as "sharkskin" which is a thin layer where the neoprene is less expanded. This makes it more abrasion resistant for squeezing between rocks and doesn't get torn in the way that fabric does.
Culturespill blog said, "An up-and-coming threesome out of Austin, Texas, The Boxing Lesson betray a rather thinly veiled affinity for Pink Floyd but they roughen the edges of that influence with an open-armed embrace of Spacemen 3, The Cure, Radiohead and Broken Social Scene. Craig Franklin from Halo-17 Australia wrote, "Not enough bands make music like The Boxing Lesson any more. Over the course of three EPs, they've managed to create some truly breathtaking and epic music that draw the dots between such seemingly disparate bands as Pink Floyd, My Bloody Valentine and David Bowie. They're equally at home writing short, concise pop songs, and kicking out the jams.
Sandblasting a stone wall Diesel powered compressor used as an air supply for sandblasting corrosion pit on the outside wall of a pipeline at a coating defect before and after abrasive blasting Abrasive blasting, more commonly known as sandblasting, is the operation of forcibly propelling a stream of abrasive material against a surface under high pressure to smooth a rough surface, roughen a smooth surface, shape a surface or remove surface contaminants. A pressurised fluid, typically compressed air, or a centrifugal wheel is used to propel the blasting material (often called the media). The first abrasive blasting process was patented by Benjamin Chew Tilghman on 18 October 1870. There are several variants of the process, using various media; some are highly abrasive, whereas others are milder.
Rupert produced some stylish mezzotints himself, and through him, after his return to England with the English Restoration in 1660, the invention became known there, which was to be the main home of the technique. Rupert described it to John Evelyn, who published it (in very enigmatic terms) for the first time in 1662, crediting Rupert with the invention: " Of the new way of Engraving, or Mezzo Tinto, Invented, and communicated by his Highnesse Prince RUPERT, Count Palatine of Rhyne, &c.;" However Rupert probably did invent the "rocker", a wide curved tool with teeth, used to roughen a whole plate, which was an essential tool in the developed technique. Rupert's artistic assistant or tutor Wallerant Vaillant (1623–77) was the first to adopt the process commercially, in Amsterdam in the 1660s.
The carinae of the hind edges were also very modified, and bifurcated (split in two) near the cervix, where they formed a flattened triangular, raised facet, which projected from the tooth crown and contacted or approached the folded carinae on the front edge of the crowns behind them (this arrangement is present in teeth 2–12). Such split carinae are known from other tetanuran theropods, where they are considered abnormalities caused by trauma, aberrant tooth replacement, or genetic factors. Though the condition in Segnosaurus was similar, it was uniformly expressed across the teeth of both dentaries, and does not appear to have been an abnormality, but served to roughen the contacts between tooth bases. The 22nd and 23rd dentary teeth of Segnosaurus were significantly smaller than the rest, almost conidont, and had an additional third carina with denticles on their inner sides.
Various mechanical ways of removing bacteria from around implants are available to be used by patients in their own homes, including but not limited to nylon-coated interdental brushes, soft-bristled toothbrushes and hard plastic cleaning instruments. These are all designed to prevent damage of the implant abutment, which would roughen the surface and lead to the accumulation of more bacteria on the surface which would contribute to the formation of more biofilms in the area. However, it was found that there were no statistically significant differences between some types of self administered antimicrobials, as they were all equally successful at maintaining the health of the soft tissues. One study was done comparing hyaluronic acid gel and chlorhexidine gel and another compared amine fluoride/stannous fluoride mouthwash to chlorhexidine mouthwash, but neither study showed either antimicrobial to be more effective at preventing peri- implant mucositis.
