It became very popular during the 1950s among black males and females of all races. It is accomplished using a hair iron or hot comb, chemical relaxers, Japanese hair straightening, [2] Brazilian hair straightening, or roller set/blowdryer styling. In addition, some shampoos, conditioners, and hair gels can help to make hair temporarily straight.
A low-cost flow straightener can be constructed using drinking straws, as they have low cost and good efficiency. The MythBusters television show used such a construction for their wind tunnel, as did an experimental wind tunnel at MIT (Maniet). The straws should be cut to equal size and placed in a frame.
The application technique is similar to the Japanese Yuko System, in that the hair is heated with flat irons to bind the product into the hair cuticle. [ citation needed ] Depending on the treatment used, the customer may have to avoid washing, wetting, pinning or constraining the hair in any way (e.g. with hair clips, pony tails, or headbands ...
In electromagnetism, the magnetic susceptibility (from Latin susceptibilis 'receptive'; denoted χ, chi) is a measure of how much a material will become magnetized in an applied magnetic field. It is the ratio of magnetization M (magnetic moment per unit volume) to the applied magnetic field intensity H.
This reduces the chi-squared value obtained and thus increases its p-value. The effect of Yates's correction is to prevent overestimation of statistical significance for small data. This formula is chiefly used when at least one cell of the table has an expected count smaller than 5.
The current replacement value is defined as what monetary value the organization places on the facility. An accurate FCI is dependent on the cost estimates developed for the facility deficiencies and current replacement value. [citation needed] The FCI is a relative indicator of condition, and should be tracked over time to maximize its benefit.
PDRC coatings such as paints may be advantageous given their direct application to surfaces, simplifying preparation and reducing costs, [37] although not all coatings are inexpensive. [62] A 2022 study stated that coatings generally offer "strong operability, convenient processing, and low cost, which have the prospect of large-scale ...
A cost-plus contract, also termed a cost plus contract, is a contract such that a contractor is paid for all of its allowed expenses, plus additional payment to allow for risk and incentive sharing. [1] Cost-reimbursement contracts contrast with fixed-price contract, in which the contractor is paid a negotiated amount regardless of incurred ...
