What's the difference between gauche and tactless?

Gauche


Definition:

  • (n.) Left handed; hence, awkward; clumsy.
  • (n.) Winding; twisted; warped; -- applied to curves and surfaces.

Example Sentences:

  • (1) The high transition enthalpy for kerasin is ascribed to a lesser accommodation of gauche conformers in the hydrocarbon chains just below the transition temperature.
  • (2) Following Nagle, we assume that the steric repulsions between chains and between head groups and the trans-gauche rotation energies are the dominant interactions in determining the transition and we describe the effect of the other interactions with a mean field approximation.
  • (3) It is also true in France , where the pro-EU, anti-cuts Front de Gauche performed so well in the first round of the presidential election.
  • (4) The crystalline structure of five enantiomeric hydrochlorides were determined, the CPhe-C-C-N torsion angle is anti-periplanar in all cases but in p-fluoro-amphetamine where it is gauche.
  • (5) Interestingly, chi 2(3) (63.6 degrees) of lysine side-chain has a gauche+ conformation unlike in most of the other structures, where it is trans.
  • (6) The vibrational Raman spectra of dimyristoyl (DMPC)-, dipalmitoyl (DPPC)-, and distearoylphosphatidycholine (DSPC)-water bilayer system were used to probe lipid hydrocarbon chain trans-gauch isomerization dynamics below the gel-liquid crystalline phase transition temperature.
  • (7) The results suggested the gauche conformation for the C alpha-C beta bond in the choline moiety, a constrained glycerol region, a magic angle orientation for the sn-2 carbonyl, and a preferred orientation close to the bilayer normal for the plane of the sn-1 carbonyl bond and acyl chain C = C bond.
  • (8) The glycosidic torsional angle, chiCN = -28.4 degrees, is in the anti region; the sugar pucker is C(2')exo-C(3')endo in a nearly pure 32H twist; and the conformation of C(4')-C(5') is gauche-gauche.
  • (9) This leads us to assume that the gauche-gauche conformation is an essental prerequisite for substrates of RNA polymerase.
  • (10) All backbone torsion angles fall into the range expected for the A-DNA form, except for the nucleotide G5, whose alpha and gamma torsion angles adopt the trans, trans conformation instead of the common gauche-, gauche+ conformation.
  • (11) The percentage of (single gauche bend + kink) conformers, relative to multiple gauche forms, decreases dramatically from 78% in the 30:1 mixture to 15% in the 10:1 mixture at 44C.
  • (12) On 5th Gear, from 2007, he talked about internet nerds reinventing themselves through social media, and offered an intentionally redneck perspective on the battle of the sexes in the deliberately gauche I'm Still a Guy.
  • (13) Part of their appeal was their apparent nonchalance, which tended to be mistaken for cool but was really, she says, just gauche bemusement.
  • (14) In contrast, a substantial population of gauche rotamers was observed for the 4-d4-DPPC.
  • (15) The following year, he and the slightly gauche new prime minister, John Major, took part in the fraught Maastricht treaty negotiations that created the modern European Union.
  • (16) A method is proposed and demonstrated for the direct determination of conformational disorder (trans-gauche isomerization) as a function of acyl-chain position in phospholipid bilayer membranes.
  • (17) Even below the main transition temperature, considerable amounts of the methylene segments of the acyl chains of lipid A were found to assume gauche conformations.
  • (18) These results favour the view that the dopamine uptake site is able to accept the substrate as the gauche rotamer.
  • (19) The IleRS-bound L-valine takes the gauche- form about the C alpha-C beta bond.
  • (20) The ribose is puckered C(2')-endo, the heterocycle is in anti position and the C(5')-O(5') bond gauche, gauche.

Tactless


Definition:

  • (a.) Destitute of tact.

Example Sentences:

  • (1) "I haven't done years of diversity training, so sometimes I say things which are probably tactless, and I don't mean to, to be honest, I don't mean to do that.
  • (2) There was one sticky moment, when Mr Cameron was reminded by a tactless journalist that he had once described his new coalition partner as "my favourite political joke".
  • (3) Jean-Paul Corap, an artist, felt the tweet was tactless.
  • (4) Little wonder that tactless buyers at Asda rubber-stamped the rapidly withdrawn "Mental Patient" fancy dress costume when "mental" is routinely worn as a badge of gregarious honour.
  • (5) the physician-originated spread of "shipyard eye," tactless behavior toward patients, and lapses in malaria eradication programs.
  • (6) Little, Will Mellor, Natalie Casey and Sheridan Smith may be the bigger names, but Louise is the comic genius - needy, self-obsessed and tactless to the point of psychopathology.
  • (7) All kinds of petty discomforts – overcrowded rooms, long hours, arbitrary or tactless treatment – were overlooked in the general sense of adventure, progress, and public service.
  • (8) I ask if she still listens to the show, and get the most comically tactless answer: “No, I don’t.
  • (9) Last year he managed to stir up a massive row over a long-dead economist when he suggested that John Maynard Keynes had no stake in the future because he was gay and childless – although he did later apologise, calling his remarks "stupid and tactless".
  • (10) A tactless candidate was another problem: Maria Hutchings came across as more Ukip and less Conservative than Ukip's own smooth-talking Diane James.
  • (11) It is true that there has been some tactless western patronising along the way.
  • (12) Though foreign media highlighted Berlusconi's characteristically tactless remark that the homeless should think of themselves as being on a "camping weekend", his slip was barely reported in Italy itself.
  • (13) In 2003, he headbutted a policeman in a Paris casino rumpus and was subsequently fined and given a suspended jail term, tactlessly telling the press that to assault a cop was “the dream of every Frenchman”.
  • (14) The rant about late payments was many things: unprofessional, relentless, vitriolic when he dealt with listeners telling him to stop moaning, self-indulgent, and tactless with a young audience who will be feeling the effects of the recession more acutely than many other radio audiences.
