Title: Method for differentiated staining of elastic and collagen fibres on histological preparation
Inventor: Dmitrieva Evgeniya Germanovna
IPC: G01N1/28
Filed: 2021-01-11
Granted: 2021-12-13
Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to the field of medicine, namely, to histology, pathological anatomy, and forensic medicine. For differentiated staining of elastic and collagen fibres, a material fixed in a 10% solution of neutral formalin is taken. The material is laid and enclosed in paraffin. Slices with a thickness of 2 mcm are made of the paraffin blocks. After deparaffinisation in xylene, the preparation is placed in dehydrated alcohol, then in 90% alcohol. The preparation is transferred from 90% alcohol to a resorcinol-fuchsin solution for 15 minutes. Then the preparation is quickly washed first in tap water, then in distilled water, then in a 1% acetic acid solution. The surface of the slice is dried with filtering paper, and a solution of durable green F.C.F. is applied thereto. After 2 minutes, the preparation is rinsed with a 1% solution of acetic acid and placed in a 1% solution of acetic acid for 5 minutes. The preparation is dehydrated, clarified and enclosed in a synthetic mounting medium. 
     EFFECT: method provides a possibility of detecting elastic and collagen fibres on one histological preparation, wherein the elastic fibres are purple and the collagen fibres are coloured in various shades of green, while also reducing the time and amount of used reagents.

Abstract: FIELD: nuclear-physical researching. 
     SUBSTANCE: invention relates to the field of nuclear-physical methods of researching wells for the purpose of prospecting and exploration of lithium in brine as a source of hydromineral raw materials in salt-bearing sections discovered by wells for various purposes. According to the claimed method, the intensities of thermal neutron fluxes are registered on a small – Jnnl sp  and large – Jnnl lp  probes of the neutron-neutron logging method - 2NNL and the intensity of the gamma radiation flux in the hard part of the PNC spectrum with an energy of more than 2.23 MeV - Jsngk is registered. The porosity function F(Kp), the saturation function F(H)nc and F(H)cnc are calculated according to the attached formulas. Then, dependences are plotted on cross-plots F(H)nnl from F(Kp), F(H)snc from F(Kp), the upper points of which are approximated by the function F(max)nnl = a⋅F(Kp)2 ± b⋅F(Kp) and F(max)sngc = a⋅F(Kp)2 ± b⋅F(Kp). Then the values ​​of the current content of chlorine and lithium obtained by 2NNL - Snnl, and the values ​​of the current content of chlorine and lithium obtained by SNGK - Ssngk are determined. Intervals containing lithium are determined by low values ​​of readings on small Jnnl sp  and large Jnnl lp  probes 2NNL and SNGKt probes, and by high F(Kp) readings when Snnk values ​​exceed Csngk values, while intervals containing lithium are characterized as zones with anomalously high reservoir pressure (AHRP).

Granted: 1984-11-08
Abstract: Bei einem bekannten Verfahren zur Herstellung von Calciumsulfathalbhydrat, insbesondere Alpha-Halbhydrat aus Rauchgas von Feuerungen wird das Rauchgas zumindest teilweise entstaubt und mit einer calciumhaltigen Waschflüssigkeit gewaschen. Das entstandene Calciumsulfit wird zu Calciumsulfatdihydrat oxidiert. Zur Entfernung der über die Kohle eingebrachten Cloride wird das Dihydrat vor Umwandlung zum Calciumhalbhydrat waschzentrifugiert. Das Waschzentrifugieren macht einen erheblichen apparativen Aufwand erforderlich. Zum Zwecke der Vereinfachung des Verfahrens wird erfindungsgemäß vorgeschlagen, daß das entstandene Calciumsulfatdihydrat in der oxidierten Waschflüssigkeit oder einem Teil derselben zu Calciumsulfathalbhydrat umgewandelt wird, ohne die Chloridanteile zuvor zu entfernen. Das durch Umkristallisation erzielte Alpha-Halbhydrat und das durch Kalzinierung erzielte Beta-Halbhydrat zeigen trotz ihres hohen Cloridanteils bessere Eigenschaften als die bisher angestrebten chloridarmen Halbhydrate.

Abstract: An electrically operated sanitary mixer tap system comprises a hollow piston (17) for adjusting the temperature, which in particular may be a rotary piston. The hollow piston (17) moves in a chamber (21) of the housing (1) of the mixer tap system, into which the flow paths (22, 23) for cold and hot water open. A particular structure (27) on the outside of the hollow piston (17) cooperates with the openings of the flow paths (23, 27) and thus determines the mixing ratio of the mixed water flowing out of the fitting. Its further path to the outlet of the sanitary fitting leads at least in regions through the interior of the hollow piston (17). Located at this point are (at least) the closing members (30, 34) of an electrically operated valve, which in this way controls the flow of mixed water to the outlet of the fitting. This arrangement of the closing members (30, 34) radially inside the hollow piston (17) facilitates a particularly space-saving construction (FIG. 4).
