Изучено влияние времени суток на двигательную активность (ДА), pH и температуру содержимого рубца (РpH и РТ) у дойных коров. Исследование проведено на 13 клинически здоровых первотелках голштинской породы при беспривязном их содержании и 3-кратном доении. Кормовой рацион, сбалансированный в соответствии с физиологическими потребностями животных, был одинаковым в течение года. Среднее значение РpH за 3 исследуемых дня у коров составило 6,39, РТ — 39,41°C и ДА — 10,05. Средний показатель РpH находился в диапазоне 5,97—6,77, РТ — 38,85—40,23°C, ДА — 3,73—15,35. Показатели стандартного отклонения для РpH были стабильны и равнялись 0,13—0,24, что составляет всего 2,03—3,76% от среднего. Стандартное отклонение РТ составляло 0,48—1,34 (1,22—3,44% от среднего). Параметры стандартного отклонения ДА были равны 1,18—7,91, или 11,74—78,71% от среднего показателя двигательной активности. Наблюдалась суточная цикличность pH рубца с максимальными значениями с 1:00 до 5:00 и минимальными — в вечерние часы. Потребление воды вызывало кратковременное (около 30 мин) снижение РТ. Двигательная активность коров характеризовалась волнообразными колебаниями без резких изменений. Дальнейшие исследования необходимо проводить для оценки влияния времени года на эти параметры.
The purpose of this study was to evaluate the effect of time of day on the pH of the rumen contents (RpH), temperature (RT) and motor activity (MA) of dairy cows. The study was conducted on 13 clinically healthy Holstein heifer cows. The cows were milked 3 times a day at 06:00, 15:00 and 22:00. The cows were kept in a barn with a loose housing system and received a feed ration throughout the year at the same time, balanced in accordance with their physiological needs. The average value of RpH for all 3 days in animals was 6.39, RT —39.41°C and MA — 10.05. The average RpH was in the range from 5.97 to 6.77, RT from 38.85°C to 40.23°C, MA from 3.73 to 15.35. The standard deviation values for acidity were very stable and ranged from 0.13 to 0.24, which is only 2.03—3.76% of the average. It can be concluded that the daily stability of acidity in animals is high. The standard deviation values for RT ranged from 0.48 to 1.34, which is only 1.22—3.44% of the average. The standard deviation values for MA ranged from 1.18 to 7.91, which is 11.74—78.71% of the average MA, from which it can be concluded that animal activity indicators are extremely unstable.

В статье проанализирована молочная продуктивность коров голштинской породы различных уровней стрессоустойчивости при роботизированной технологии доения. Исследования проведены на базе племенного предприятия Свердловской области. Выборочная совокупность (n=120) состояла из коров молочного направления продуктивности различного возраста. Исследуемых животных распределили по уровню устойчивости к стрессу (высокий, средний, низкий) относительно концентрации гормонов в сыворотке крови, рефлекса торможения молокоотдачи и синхронности молоковыведения. Установлено, что более высокая и достоверная разница в удое за первые 100 дней лактации оказалась у коров, распределенных по коэффициенту синхронности молокоотдачи (940,2 кг при P<0,001); в удое за 305 дней лактации — у коров, распределенных по уровню гормонов в крови (438,0 кг) и коэффициенту синхронности молокоотдачи (404,2 кг); в массовой доле белка в молоке — у коров, распределенных относительно рефлекса торможения молокоотдачи (0,06% при P<0,05) и коэффициента ее синхронности (0,12% при P<0,01); в живой массе — у коров, распределенных относительно рефлекса торможения молокоотдачи (18,6 кг). Рекомендуем предприятиям, специализирующимся на производстве молока, включать оценку уровня стрессоустойчивости стада в перечень показателей при отборе коров для роботизированного доения, учитывая при этом рефлекс торможения молокоотдачи и коэффициент синхронности молоковыведения.
The article analyzes the milk productivity of Holstein cows of various levels of stress resistance with robotic milking technology. The research was conducted on the basis of a breeding enterprise in the Sverdlovsk region. The sample population (n=120) consisted of dairy cows of various ages. The studied animals were distributed according to the level of resistance to stress (high, medium, low) relative to the concentration of hormones in the blood serum, the reflex of inhibition of lactation and synchronicity of lactation. It was found that a higher and more significant difference in milk yield for the first 100 days of lactation was found in cows distributed by the coefficient of synchronicity of milk production (940.2 kg at P<0.001); in milk yield for 305 days of lactation — in cows distributed by the level of hormones in the blood (438.0 kg) and the coefficient of synchronicity of milk production (404.2 kg); in the mass fraction of protein in milk — in cows distributed relative to the reflex of inhibition of milk production (0.06% at P<0.05) and its synchronicity coefficient (0.12% at P<0.01); in live weight — in cows distributed relative to the reflex of inhibition of milk production (18.6 kg). We recommend that enterprises specializing in milk production include an assessment of the level of stress resistance of the herd in the list of indicators when selecting cows for robotic milking, taking into account the reflex of inhibition of milk production and the coefficient of synchronicity of milk production.
Instantaneous deposition-rate modulator for vacuum vapor deposition: fabrication of polarization gradated organic film
Authors: Kim Sowon , Ohara Masahiro , Fukagawa Hirohiko , Ishii Hisao 
Published: January 2025

Abstract
The molecular orientation and properties of vapor-deposited organic films are essential for device performance and typically governed by the deposition rate. Controlling the orientation during film growth allows the optimization of local properties from the interface to the bulk region. However, conventional deposition faces challenges in rapid wide-ranging rate adjustment due to the required stabilization time. We introduce a velocity selector that enables instantaneous deposition rate changes by modulating the molecular transmission through blade rotation. Using the proposed selector, we precisely control the spontaneous orientation polarization in Alq3 films by continuously varying deposition rates, achieving flexible polarization grading within organic films.
Spin polarised quantum conductance in 1D channels
Authors: Montagu Henry , Farrer Ian , Ritchie David , Kumar Sanjeev 
Published: January 2025

Abstract
We report the experimental observation of a spin-polarised conductance plateau at e
2/h in a clean one-dimensional (1D) quantum wire defined by back-gated, split gate devices on a GaAs/AlGaAs heterostructure in the absence of a magnetic field. The 1D devices were fabricated using standard lithography techniques consisting of split gates, and a custom-designed back gate allows for the modulation of carrier density within the 1D channel. The differential conductance shows regular quantised plateaus in units of 2e
2/h as a function of back gate voltage, including the observation of the 0.7(2e
2/h) conductance anomaly. The 0.7 anomaly, on reducing the charge carrier concentration, gradually converts into a 0.5(2e
2/h) structure, indicating the lifting of spin degeneracy in the absence of a magnetic field. Our results suggest the potential of low-density 1D devices for applications in spintronics and quantum electronics.

Published: January 2025

Abstract
We describe a local fluctuating magnetic field detection of Fe3O4 superparamagnetic core–shell particles via relaxometry of an ensemble of NV centers in a diamond. A thin diamond chip enables optical access to the contact position of the magnetic particle through the backside. A significant drop in NV relaxation time near the particle was observed and was evaluated using a model incorporating ensemble NVs and magnetic particles. Additionally, the local magnetization curve (B-H curve) was measured by analyzing ODMR frequency splitting under external magnetic fields aligned with an NV axis. This study expands the NV sensing to applications involving collective superparamagnetic particles.

Published: January 2025

This work aims to study the mechanical properties of spinel­based glass ceramics in relation to their structure. The tasks of the work are: comparative analysis of transparent high­strength ceramic and glass­ceramic materials; study of the properties of spinel­based glass­ceramic materials in connection with their structure; recommendations on the use of high­strength glass­ceramic materials and prospects for their development.
Application areas of spinel­based ceramic materials as multifunctional products were analyzed. The perspective of using glass­ceramic materials as protective elements of optics, aviation and ground transport was investigated.
The presence of the crystalline phase was established using X­ray phase analysis, which was carried out at the DRON—3 installation. Petrographic studies were carried out using an optical polarizing microscope NU—2E. The Vickers hardness and the crack resistance index were determined by indenting the Vickers pyramid with a load of 5000 g on the pyramid for 10 measurements using the TMV—1000 device. Impact toughness was determined according to (EN1288—1:2000). The density of materials was measured by the method of hydrostatic weighing in toluene. The modulus of elasticity of materials was investigated using the device “Sound—107” by the method of determining the resonance frequency of oscillations with a relative error of ≈  0.2 %.
Based on a detailed analysis of the structure of glass­ceramic materials, the composition of magnesium­aluminosilicate glasses for obtaining high­strength glass­ceramic materials with high mechanical properties and adjustable light transmission has been substantiated. The technological modes of cooking and heat treatment of glass­ceramic materials were selected. The priority of forming a self­bounded micro­ and nanostructure of glass­ceramic materials under conditions of low­temperature heat treatment to ensure their high mechanical properties was shown. The determining influence on the optical and mechanical properties of glass­ceramic materials of spinel crystalline phases and their dimension, as well as the formation of an oriented structure by directional crystallization, was established. Mechanical (HV = 8.7 ÷ 10.5 GPa; K1C = 4.0 ÷ 6.0 MPa · m1/2; σст = 550 ÷ 650 MPa; KCU = 4.0 ÷ 5.5 kJ/m2) and optical properties of glass­ceramic materials (T = 72 %) and their density (ρ = 2550 ÷ 2850 kg/m3).
A comparative evaluation of known transparent ceramic and glass­ceramic materials indicates the expediency of using the developed materials both in the glazing of aviation equipment and for the protection of special ground equipment.

A infertilidade feminina é definida como a dificuldade de uma mulher engravidar após um ano de relações sexuais regulares e sem o uso de métodos contraceptivos. Essa condição pode ter diversas causas, desde fatores hormonais até problemas estruturais nos órgãos reprodutivos que causam infertilidade na Síndrome dos Ovários Policísticos (SOP) e também a Obstrução das trompas de falópio que podem ser causada por infecções, endometriose ou cirurgias anteriores, assim como identificar os possíveis tratamentos disponíveis. Sabe-se que a SOP é o distúrbio endócrino mais comum na idade fértil, o qual acomete até 10% das mulheres, apresentando alterações hormonais, reprodutivas e metabólicas. Sendo assim, para seu diagnóstico são necessários pelo menos dois critérios: oligo-ovulação ou anovulação, hiperandrogenismo clínico e/ou laboratorial e ovários policísticos identificados ao exame ultrassonográfico. De acordo com a avaliação clínica de cada paciente, têm-se entre as opções terapêuticas mudanças nos hábitos de vida como primeira escolha, por exemplo, prática de atividade física e alimentação saudável, além da terapia farmacológica, uso de hormônios, fertilização e cirurgia. Entretanto, alguns efeitos colaterais no tratamento ainda causam preocupação, como o risco de gestação múltipla, o que sinaliza a necessidade de mais estudos que promovam melhoria no prognóstico dessas mulheres.
