ABSTRACT Latex allergy is still a crucial concern for latex glove users and manufacturers. The major reason is that the possibility of allergy stems from the soluble proteins that reside within latex gloves that may be transferred into the body of the user. Conventionally, the protein level quantification by the colorimetric measurement test is usually complex and requires a long processing time, sophisticated equipment, and highly trained specialists to perform the test. Because of the costly, lengthy, and labor-intensive nature of the tests, these methods are not beneficial for the efficiency of product development. Hence, a new computerized measurement method is proposed to measure protein levels. The prepared latex glove samples were chemically treated by Bradford reagent. Then, the samples were scanned and analyzed by novel algorithm, namely, the downhill searching algorithm (DSA), to determine the dominant color intensity. A total of 108 data were obtained after DSA analysis, and the developed data were validated with protein concentration data provided by the Malaysian Rubber Board. A good correlation is observed between both data.

The analysis of a new class of measuring instrument for heat quantities based on the use of multi-valued measures of heat conductivity of solids. For example, measuring thermal conductivity of solids shown the fallacy of the proposed approach and the illegality of the use of the principle of ambiguity to intensive thermal quantities. As a proof of the error of the approach, the relations for the thermal conductivities of the component elements of a heat pump that implements a multi-valued measure of thermal conductivity are given, and the limiting cases are considered. In two ways, it is established that the thermal conductivity of the specified measure does not depend on the value of the supplied heat flow. It is shown that the declared accuracy of the thermal conductivity measurement method does not correspond to the actual achievable accuracy values and the standard for the unit of surface heat flux density GET 172-2016. The estimation of the currently achievable accuracy of measuring the thermal conductivity of solids is given. The directions of further research and possible solutions to the problem are given.
