Title: Neutron supermirror polariser
Inventor: Syromyatnikov Vladislav Genrikhovich
IPC: G21K1/16
Filed: 2018-12-13
Granted: 2019-09-10
Abstract: FIELD: physics. 
     SUBSTANCE: invention relates to neutron supermirror polariser. Polariser consists of a transmission neutron polariser and a second neutron super-mirror polariser located close to the transmission neutron polariser. Newly introduced polariser provides high negative polarization of the beam at a wide angle range exceeding the total angular width of the beam incident on the polariser input, and which is made in the form of a multichannel neutron guide with straight channels in the form of a set of plates compressed between each other without air gaps, which are made of material which weakly absorbs neutrons. Device design is made so that neutrons (-) of beam spin component are reflected from walls of second polariser with high reflection coefficient, and neutrons (+) of spin component – with low coefficient of reflection. This will lead to suppression of peaks (+) of the spin beam component, which worsen polarization of the beam at the output of the first polariser. 
     EFFECT: high degree of polarization of the output beam in a wide angular range, which provides creation of a wide-aperture super-mirror polariser with suppression of the contribution (+) of the spin component for any range of the incident neutron beam.

Abstract: FIELD: agriculture; animal breeding. 
     SUBSTANCE: invention relates to a method for selection of breeding bulls for resistance to mastulia by indices of breeding value based on the number of somatic cells in milk. Method includes monthly individual testing of daughters of all bulls in herds by number of somatic cells (KSK) in milk. Average lactation absolute CSC in thousands/cm 3  (ACAS) in daughters of each bull is converted into points by the formula: logarithm of CSC in scores = Log 2  (ASC/100,000) + 3. Average scores for lactation are used to calculate bull breeding value (CPI) by CPI = 2 * (D – P) * b formula, where D is logarithm of CSC in bull daughters, point; P is logarithm of CSC in cows of population, point; b is coefficient of recurrence (regression) of indicators of future daughters of this bull on indicators available. Based on the developed scale, the CPI is used to distribute producers into breeding categories – improvers, neutral agents, malignant resistance agents. At that, bulls with a breeding value index minus 1.012 and less than a point are related to category 1 improvers, with an index from minus 0.227 to minus 1.011 – to improvers of 2nd category, with an index from minus 0.226 to plus 0.211 – to neutral ones, with index from 0.212 to 1.101 – to deteriorators, with index plus 1.102 and more – to extreme deteriorators.

Abstract: Изобретение относится к ледоведению и ледотехнике и может быть использовано для определения внутреннего строения, распределения прочности, температуры, солености и плотности льда в торосах и стамухах, а также позволяет оценивать размер, как всего торосистого образования, так и его частей - паруса, консолидированного слоя и неконсолидированной части киля. Внутреннее строение ледяного образования (границы слоев льда различной плотности, границы и толщина консолидированного слоя, пористость) определяется при помощи термобурения водяным или электрическим буровым устройством по заданной сетке профилей; физико-механические характеристики льда в ледовых торосистых образованиях определяются на отобранных кернах в характерных местах, выбранных при термобурении. При этом локальная прочность льда определяется при помощи зонд-индентора в скважинах, полученных при отборе кернов для паруса, консолидированного слоя и неконсолидированной части киля. Определение размера паруса торосов и стамух осуществляется беспилотным летательным аппаратом мультироторного типа, снаряженным фото- и видеокамерой, а определение координат и высоты паруса проводится в узловых точках сетки профилей при помощи спутникового геодезического устройства на базе глобальной навигационной системы ГЛОНАСС/GPS или обеспечивается при помощи тахеометрической съемки в узловых точках сетки профилей с привязкой к уровню моря. Определение размеров киля торосов и стамух проводится профилирующим гидролокатором бокового обзора, который опускается в подводное положение через майны, вырезанные в ровном льде вокруг тороса или стамухи, а визуальное уточнение работы гидролокатора осуществляется при помощи телеуправляемого подводного аппарата с фото- и видеокамерой высокого разрешения, который опускается в те же майны, что и гидролокатор.
