    CLASSIFICATIONS OF TECHNICAL MEANS OF PHYSICAL TRAINING AND ASSESSMENT OF THEIR EFFECTIVENESS BASED ON BIOMECHANICAL PRINCIPLES OF STRUCTURING MOTOR ACTIONS by M. B. Sotsky

    Published 2017-02-01
    “…As a result, digital indexing of the above targets was proposed which allows to group and present the technical means in the form of matrix depending on the combination of the indexes and to determine promising trends in novel developments finding the blank areas in the matrixIn accordance with the proposed classification by the example of technical means of strength training, the concept of the biomechanical efficiency of the devices is introduced for the first time, for which specific numerical coefficients were introduced such as spatiality, inertia and energy dissipation.The paper presents a qualitative analysis of the typical means of strength training in terms of biomechanical efficiency, which showed the prospect of engineering technical devices with many degrees of freedom using the friction method of creating the resistance when training.…”

    Determination of Tungsten, Molybdenum and 5 Associated Elements in Tungsten-Molybdenum Ore by Inductively Coupled Plasma-Optical Emission Spectrometry with Direct Sintering by Zhou SONG, Yiping JI, Weihua WANG, Shaomin FANG, Jie YANG, Huoyan LUO, Yuqi ZHOU

    Published 2023-10-01
    “…It is insoluble in hydrochloric acid, nitric acid and aqua regia, and the alkali melting and mixed acid dissolution method was often selected for sample digestion. However, the matrix effect cause by the alkali melting method seriously affects the accuracy and detection limit of instrument testing; the acid dissolution method has low dissolution efficiency for tungsten, molybdenum and other insoluble elements, and requires a long time and a complex pretreatment process by using a variety of inorganic strong acids such as hydrofluoric acid and aqua regia, which can also cause damage to the analytical and testing instruments.OBJECTIVESTo develop a simple and efficient method for quantitative analysis of tungsten and molybdenum and its associated elements in tungsten-molybdenum ore.METHODSBased on alkaline melting and acid dissolution, a method was established by inductively coupled plasma-optical emission spectrometry (ICP-OES) with direct sintering and complex extraction of hydrochloric acid-phosphoric acid-citric acid. …”
