sexual tension

A tension, awkwardness, or underlying unease in the relationship of two people resulting from a strong mutual sexual attraction between them that has not been consummated. Just ask Chuck out already—I'm sick of being around you two and witnessing all your sexual tension. I can just feel the sexual tension every time Matt and I are together.

you could cut (something) with a knife

Something intangible or non-solid is incredibly thick, palpable, or poignant. The air was so humid as we stepped off the plane if felt like you could cut it with a knife. The entire dinner was so awkward you could cut the tension with a knife.

* Identify the forces as compressive or tensional and pair them.
Por mi parte, considero que el caracter tensional entre lo narrado y lo no narrado radica en que lo primero adquiere coherencia al funcionar como una region paradigmatica que ha sido recuperada y puesta en <<orden>>, y cuyo significado pleno depende en gran medida de su relacion con lo dejado en penumbras.
Tensegrity is a structural system which is known due to the distinctive compressive elements that are floated within a Tensional Network.
Thus, the geological setting was tensional in the tectonic eras of Caledonian (from Sinian to Late Silurian) and Hercynian (from Devonian to Late Permian) periods, when the siliceous rocks had the largest distribution number with the widest distribution.
El formato se dividio en tres partes: primera, registro de los antecedentes de los tipos de dolor (como el dolor regional orofacial y tensional de la cabeza), cansancio o debilidad muscular orofacial, ruidos en la ATM en apertura o cierre y la presencia o no de otalgia primaria de origen otologico.
This has led to the publication of the first text dedicated to this tissue, entitled Fascia: The Tensional Network of the Human Body.
Ademas la duracion del dolor es importante para diferenciar la migrana de la cefalea tensional, ya que si el dolor se extiende entre 4-72 horas es tipico de migrana, una duracion menor de 4 horas es tipica de cefalea tensional.
It has been proposed that hypertrophy can be stimulated not only by weights that induce tensional stress with resulting muscular damage, but also by stimuli capable of imposing hypoxia or metabolite accumulation within the muscle.
(4), estudando os aspectos clinico-epidemiologicos das cefaleias, entre estudantes universitarios de Medicina e Psicologia, determinaram a prevalencia de cefaleia distinguindo as principais modalidades apresentadas pelos estudantes: enxaqueca ou cefaleia do tipo tensional e determinaram o grau de interferencia das cefaleias nas atividades dos estudantes, contribuindo para Educacao Sociocentrica em Neurologia.
A hipertrofia muscular ocorre devido principalmente a sobrecarga tensional e metabolica: sobrecarga tensional, ocorrida principalmente ao treinamento com cargas elevadas, causa a hipertrofia miofibrilar devido ao aumento do conteudo de proteinas contrateis nas miofibrilas, que proporciona o aumento no numero e tamanho das miofibrilas; sobrecarga metabolica que causa a hipertrofia sarcoplasmatica (aumento de creatina fosfato, glicogenio e agua que ocorre devido ao tempo prolongado de contracao), o que sugere repeticoes elevadas e/ou intervalos curtos.
The major fibrous elements are collagen fibers (type I and type III collagens), which play a role in resisting tensional force and holding teeth in the alveolar socket (Shuttleworth & Smalley; Kusters et al.).
The seismicity is very intense along the Nazca-North Andes, Caribbean-North American and North Andes-South American collision zones and associated with regional tectonic compressional stresses that have locally increased and/or diminished by compressional and tensional stress, respectively, due to crustal thickness variations.
It is believed that the NW-SE orientation is largely a result of compressional tectonism (mountain building processes) and the NE-SW orientation is largely a result of subsequent tensional movement (faulting, shearing).
