Published: January 2023

Introduction: The direct-contact condensation (DCC) of steam under water injection is the basic thermodynamic process of the bubble deaerator. In order to understand the complex coupling behavior of strong turbulence and fast phase-change heat transfer involved in the process.Methods: This study uses a visualized method and convective heat transfer model.Results: Since the contact area is affected by steam injection flow and sub-cooled degree is affected simultaneously, the trend of the condensation heat-transfer coefficient depends on the degree of their respective effects under each condition, and the maximum variation of the coefficient exceeds 104 W/m2.°C. Moreover, they still effect the period of steam plume, and the maximum variation of the period was beyond 80 ms.Discussion: Calculated the average condensation heat transfer coefficient and then produces the variation law of heat transfer coefficient under various conditions in one steam plume evolution period.

IntroductionUnder temperate latitudes, reproduction in Ovis aries displays a marked seasonality, governed by the photoperiod. In natural conditions, the transition between sexual rest and sexual activity in both sexes is induced by the decrease of day light. Meanwhile, specific odors emitted by a sexually active male are able to reactivate the gonadotropic axis of anovulatory ewes. This physiological effect is called “male effect”, precisely ram effect in the ovine species. We have previously shown that the secreted proteins, namely Olfactory Binding Proteins (OBP), contained in the nasal mucus constitute the olfactory secretome (OS), the composition of which is determined by the status of oestrus cycle of females and differs between sexual rest and sexual activity periods. The objective of this study was to test the hypothesis that exposure to sexually active male can also modify the composition of ewes olfactory secretome during a male effect, as well as hormones produced by the reactivation of the oestrus cycle in sexual activity period under natural conditions.MethodsWe have set up a new non-invasive protocol of nasal mucus sampling and collected it from 12 ewes at different times during a ram effect. We analyzed the composition of their olfactory secretome by proteomics, mainly SDS-PAGE and MALDI-TOF mass spectrometry. As post-translational modifications of OBPs were a hallmark of ewes' sexual activity period, we were looking for glycosylation by western-blot and mass spectrometry.ResultsThe efficiency of male effect was low in stimulated ewes as only 3 females displayed elevated progesterone levels in their blood. Besides, half of control ewes (non-stimulated ones) were cycled. We noticed a common OS profile in ewes in anoestrus, versus OS of cycled ones. A very clear and important result was the apparition of O-GlcNAcylation, previously detected only in sexual activity, after only 30 min of male introduction into the flock.DiscussionThis exploratory study paves the way for further experiments with larger flock to confirm and reinforce these results, and for eventually exploiting the nasal mucus as an indicator of females' receptivity to male odors.

Published: January 2023

Objectives: Parents are often torn between their parenting roles in the family and working roles at the workplace. This study focused on the associations of parental employment with children’s screen time (ST) on weekdays, weekends, and during the entire week.Methods: Unbalanced panel data including 2,977 children (aged 0–17 years) from five waves of the China Health and Nutrition Survey data from 2004 to 2015 were utilized. Two-way fixed effects models were fitted to examine the associations of parental employment status, working hours, and overwork with children’s ST.Results: Compared to unemployment status, maternal formal employment positively predicted children’s ST on both weekdays and weekends, while maternal informal employment was associated with increased children’s ST on weekends. The more hours they worked, the more time their children spent using screens. Neither employment status nor the overwork of fathers was significant.Conclusion: Parental employment, especially maternal employment, was linked with the ST of children. More childcare-friendly labor policies are needed to promote healthy lifestyles among the next generation.

Feralolide, a dihydroisocoumarin, was isolated from the methanolic extract of resin of Aloe vera. The present study aims to investigate the in vivo ability of feralolide to ameliorate memory impairment induced by scopolamine using a battery of in vitro assays, such as antioxidant and acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) inhibition, and in vivo animal models, including elevated plus maze, Morris water maze, passive avoidance, and novel object recognition tests. Feralolide caused a concentration-dependent inhibition of AChE and BuChE enzymes with IC50 values of 55 and 52 μg/mL, respectively, and antioxidant activity against 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2′-azinobis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) with IC50 values 170 and 220 μg/mL, respectively. Feralolide reversed the scopolamine-induced amnesia as indicated by a dose-dependent decrease in escape latency, path length, and passing frequency in the Morris water maze test compared with the relevant control. The compound also significantly increased the discrimination index in a dose-dependent manner in NORT and decreased transfer latency in EPM, reflective of its memory-enhancing effect. Furthermore, feralolide also caused significant dose-dependent elevation in the step-down latency (SDL) in the passive avoidance test. The results indicated that feralolide might be a helpful memory restorative mediator in treating cognitive disorders such as Alzheimer’s disease.

Published: January 2023

Background: The London Classification for anorectal physiological dysfunction specifically proposes rectoanal areflexia (RA), which means the absence of a rectoanal inhibitory reflex (RAIR) based on a manometric diagnosis. Although RA is not observed in healthy people, it can be found in adult patients with functional constipation (FC). This study describes the clinical manifestations of adult patients with FC and RA and their response to biofeedback therapy (BFT). Methods: This retrospective study reviewed the reports of high-resolution anorectal manometry (HR-ARM) and the efficacy of BFT in adult patients with FC. In addition, the Constipation Scoring System (CSS) scale, Patient Assessment of Constipation Symptoms (PAC-SYM) scale, Patient Assessment of Constipation Quality of Life (PAC-QOL) scale, Zung’s Self-Rating Anxiety Scale (SAS), Zung’s Self-Rating Depression Scale (SDS), balloon expulsion test (BET), and the use of laxatives were assessed. Results: A total of 257 adult patients diagnosed with FC were divided into the RA group (n = 89) and the RAIR group (n = 168). In the RA and RAIR groups, 60 (67.4%) and 117 (69.6%) patients, respectively, had dyssynergic defecation (DD) during simulated defecation. Type II pattern of dyssynergia was most frequently observed in both groups. Compared with the RA group, the RAIR group showed a higher CSS score, physical discomfort score, and prevalence of inadequate relaxation of the anal sphincter (p < 0.001, p = 0.036, and p = 0.017, respectively). The anxiety and depression scores were not different between the two groups. The proportion of patients using volumetric and stimulant laxatives and their combination was significantly higher in FC patients with RA, whereas the efficacy of BFT was significantly lower (p = 0.005, p < 0.001, p = 0.045, and p = 0.010, respectively). Conclusion: Adult FC patients with RA may suffer more severe constipation and have a lower efficacy of BFT compared with those with RAIR.

The objective of this study was to investigate the fermentation characteristics and nutritional value of A. sativa genotypes ensiled either solely or in combination with P. purpureum 16791. Three different A. sativa genotypes (SRCPX80AB2806, ILRI_5527A, and ILRI_5526A) were harvested at the dough stage and ensiled solely or in combination with equal parts of P. purpureum 16791 with the addition of 3% molasses for all treatments in a completely randomized design with three replications over a period of 45 days. P. purpureum harvested at 60 days was ensiled and used as a control treatment. All treatments were evaluated for fermentation characteristics (pH, temperature, physical properties, and flieg point) and subjected to chemical analysis. The results showed that ensiling A. sativa ILRI_5527A, in combination with equal parts of P. purpureum 16791, produced the best silage with a significantly lower pH of 3.52. Optimal temperature (25 °C), nutrient losses based on the total dry matter (2.17%), gas (3.74%), and effluent (4.28%) were significantly (p < 0.0001) lower for T6 compared to the others. The dry matter recovery rate of T6 was significantly (p < 0.0001) higher than that of the others. T6 ranked first in the quality of physical properties (smell, color, mold, and texture). The highest dry matter (24%), organic matter (96.80%), crude fat (3.32%), and metabolizable energy (10.05 MJ/kg DM) were recorded for T6. The flieg score for T6 silage (96.6%) was also better than the others. In conclusion, ensiling A. sativa ILRI_5527 with equal parts of P. purpureum 16791 and the addition of 3% molasses improved fermentation characteristics and silage quality.

The Role of Local Communities in the Discourse of Controversial Heritage of Norway and Estonia
Authors: Paulus Ave , Brekke Arnstein Bard 
Published: January 2023

The current paper analyses the paradigm shifts in the discourse of heritage sites with tragic personal stories, memories, and remains, emphasising local communities' role in reframing controversial heritage in Norway and Estonia. Although these stories are from different cultures and places, they all spin around the same - how do we deal with the most delicate strings in the human mind, beliefs, sorrows, and dignity. The sites under discussion are "ghosts" of the tragedies of the past century. Among heritage communities, states and experts, there were intense debates about the values and fate of those areas. Besides several historical, political and socioeconomic issues, personal wounds were reconciled. The first case describes the heritage communities' initiatives in accessing and reconciling values of contested Cold War heritage - Suurpea Naval Base erected during Soviet Occupation and deportations on the coasts of Estonia. The second case deals with the initial demolition and later recognition of Sami burial sites and sacred landscapes of Arctic Norway, re-gaining the rights to Saami heritage and restitution. These cases highlight the importance of inclusiveness while dealing with conflicting histories, reconciliation, restitution, and dignity of heritage and communities concerned. Authors rely on a holistic concept of cultural heritage. Cultural communities, spirit and feeling of their presence are essential indicators of character and sense of place. The authors show the benefits of a people-centred approach towards heritage as the basis of transformative change in heritage protection. The authors` positions are not purely academic – they have been involved in defining and protecting the cultural heritage of the areas under discussion.

Fabrication of thin ferroelectric Hf0.5Zr0.5O2 films by millisecond flash lamp annealing
Authors: Tanimura Hideaki , Ota Yuto , Kawarazaki Hikaru , Kato Shinichi , Nara Yasuo 
Published: January 2023

Abstract
We used millisecond flash lamp annealing (FLA) to form thin ferroelectric Hf0.5Zr0.5O2 (HZO) films with thicknesses of less than 10 nm and with remanent polarization up to 30 μC cm−2. A clear dependency of the polarization on the annealing temperature and time was observed, indicating that the precise management of the thermal budget is a key factor in forming ferroelectric HZO. We also show and compare the process windows within which ferroelectricity in 10 and 5 nm samples is obtained. The results show that a high thermal budget is necessary for thinner samples. We examined the endurance characteristics and a greater endurance compared to rapid thermal annealing treatment was observed with more than 1010 cycles without breakdown confirmed in 5 nm thick samples. The data indicates that there is the possibility of further thickness scaling whilst retaining highly durable characteristics for films annealed by FLA.
High sensitive vector measurement of nonlinear harmonic responses in surface acoustic wave/bulk acoustic wave radio frequency devices
Authors: Himata Seiya , Omori Tatsuya 
Published: January 2023

Abstract
This paper proposes a high-sensitive measuring method for nonlinear harmonic responses in radio frequency (RF) SAW/BAW devices using a lock-in amplifier. The proposed system could detect the nonlinear complex harmonic responses generated in an RF SAW resonator, even if the responses are weaker than −140 dBm. The detection limit is extended by around 10 dB compared with the conventional technique using a cross-domain analyzer.

Published: January 2023

Abstract
A real-time temperature measurement technique with high spatial (≤20 μm) and temporal (≤1 μs) resolutions for SiC wafers during ultra-rapid thermal annealing (URTA) has been developed based on optical-interference contactless thermometry (OICT). This technique consists of hardware (OICT imaging setup) and software (fast temperature extraction program). Under URTA by atmospheric-pressure thermal plasma jet, a clear variation of optical-interference fringes was observed by a high-speed camera and then analyzed by a fast temperature extraction program using image preprocessing and a database. 3.5D (x, y, z and time) temperature distribution in SiC wafer was obtained within 0.43 s.

Published: January 2023

Abstract
Using a newly developed submicron focusing system equipped with a large-aperture Wolter mirror with a precisely figured surface, we irradiate a Ni thin film coated on a silicon substrate with femtosecond extreme ultraviolet (EUV) laser pulses, generated as high-order harmonics of near-infrared femtosecond laser pulses. At the fluence of up to 100 mJ cm−2 at the sample surface, we show that the surface morphology can be modified with a submicron spatial resolution and that a protruding structure is formed when the fluence is 60–70 mJ cm−2, exhibiting a characteristic feature of the femtosecond EUV light processing of a thin metal surface.

Authors: Guan Huijuan , Song Rongguo , Tong Cong , Zhao Xin , Yang Yingping , He Daping 
Published: January 2023

Abstract
In this paper, a conformal CSRR derived sensor array with two resonant frequencies based on a graphene assembled film (GAF) is proposed to detect and determine the direction of submillimeter cracks on aluminum plates. The GAF sensor array consists of a microstrip line, a dielectric substrate and a reference ground with two CSRR derived resonant structures. The GAF sensor array has a high sensitivity of 270 MHz for the curved aluminum plate with a crack width of 0.2 mm. In addition, the CSRR derived resonant structure array of the GAF sensor effectively detects the direction of the crack.

Authors: Li Yan , Zhang Jin , Wu Feng , Liu Guanghui , Xiao Xiaosheng 
Published: January 2023

Abstract
We demonstrate fast dual-comb spectroscopy based on a high-repetition-rate dual-wavelength erbium-doped fiber laser with a large repetition rate difference. It can operate in three different dual-wavelength states with repetition rate differences of 4.32, 2.74 and 3.635 kHz, respectively. To the best of our knowledge, the corresponding refresh time can be as low as 231 μs, which is the fastest in dual-comb spectroscopy using a single fundamentally mode-locked all-fiber laser. The high repetition rate of approximately 154.68 MHz provides a maximum optical frequency bandwidth of 4.37 THz. Dual-comb spectroscopy was used to measure the transmittance curve of the Fabry–Perot etalon.

Published: January 2023

Введение: Современные мировые тенденции употребления растительного и животного белка склоняют мировое общество в сторону превалирования потребления продуктов питания, обогащенных растительным белком. Это связано с несколькими преобладающими аспектами: получение растительного белка является более экономически выгодным, экологически безопасным и потенциально несет более ценную пищевую компоненту. Известно, что растительный белок усваивается в организме на уровне 61-80% в виду наличия антипитательных веществ и имеет неполноценный аминокислотный состав. Следует изыскивать новые научные подходы повышения биодоступности пищевых компонентов растительного белкового сырья.Объекты и методы исследования: В статье приводится поэтапный алгоритм проектирования белоксодержащего пищевого продукта с включением в стадию разработки способа снижения антипитательных свойств растительного сырья. В качестве белкового ингредиента выбран горох, который подвергался тонкому измельчению совместно с ферментативным препаратом с последующей стадией ферментативного гидролиза при оптимальных параметрах. Гороховый гидролизат использовали в замесе дрожжевого опарного теста.Результаты и их обсуждение: На процесс замеса теста оказывает влияние ряд факторов, которые описаны в работе в виде параметрической схемы технологического процесса. На основе структурно-параметрический анализа проведен комплексный эксперимент влияния двух варьируемых факторов (количества дрожжей и гидролизата) на количество сухого нерастворимого остатка.Выводы: Выведено уравнение регрессии, которое позволяет анализировать технологический процесс и контролировать его. В статье приводятся данные по содержанию водорастворимых веществ, белка, свободных аминокислот в готовых хлебобулочных изделиях, которые позволяют судить об эффективности стадии механоферментативного гидролиза. Общее количество водорастворимых веществ в образцах с гидролизатом увеличивается более, чем в 2 раза. Разработка новых изделий с применением стадии ферментации – это перспективное направление индустрии питания, которое позволяет получать качественно новые изделия с высокой пищевой и биологической ценностью.
Where’s Wanda? The influence of visual imagery vividness on visual search speed measured by means of hidden object pictures
Authors: Monzel Merlin , Reuter Martin 
Published: January 2023

AbstractPrevious research demonstrated effects of visual imagery on search speed in visual search paradigms. However, these effects were rather small, questioning their ecological validity. Thus, our present study aimed to generalize these effects to more naturalistic material (i.e., a paradigm that allows for top-down strategies in highly complex visual search displays that include overlapping stimuli while simultaneously avoiding possibly confounding search instructions). One hundred and four participants with aphantasia (= absence of voluntary mental imagery) and 104 gender and age-matched controls were asked to find hidden objects in several hidden object pictures with search times recorded. Results showed that people with aphantasia were significantly slower than controls, even when controlling for age and general processing speed. Thus, effects of visual imagery might be strong enough to influence the perception of our real-life surroundings, probably because of the involvement of visual imagery in several top-down strategies.
