Transporting hatching eggs from Hungary and incubating them abroad revealed lower hatchability compared to when the eggs were incubated in Hungary. Following transport, there were higher embryo losses and, notably, more malformed embryos. The aim of these initial trials was to determine if a testing device （crazy fit massage machine （CFM machine）） was able to replicate and model the mechanical impacts experienced during transport and reproduce the reduction in hatchability and increase the level of malformed embryos as observed in commercial practice. Tinytag~ high sensitivity shock and vibration loggers were used to monitor the impacts under field and trial conditions. Applying single 10 min treatments on the CFM machine, which used the same frequency （10-30 Hz） as the eggs experience under field conditions, induced the negative effect of transport, and lower hatching results were experienced. Three trials were conducted. Treated eggs in Trials 1 and 2 received automatically and periodical changing vibration in a range between 10-30 Hz for 10 min while in Trial 3 two different levels of impact were applied at 20 Hz and 30 Hz, respectively. Hatchability decreased due to the treatment significatly only in Trial 3. Significant differences were also detected in early dead levels in Trials 2 and 3 and the occurrences of malformation in Trials 1 and 3. All these results are in accordance with the field experience. Thus, the trials which examined the equipment were able to produce mechanical impacts that were repeatable in order to set up statistically reliable trials on hatching eggs.

This review is part two of three, which will present an update on the classification of gastrointestinal submucosal tumors. Part one treats of the diagnosis and part three of the therapeutic methods regarding gastrointestinal submucosal tumors. In the past there has been some confusion as to the classification of gastrointestinal submucosal tumors. Changes in classifications have emerged due to recent advances in mainly immunohistochemistry and electron microscopy. The aim of this paper is to update the reader on the current classification. Literature searches were performed to find information related to classification of gastrointestinal submucosal tumors. Based on these searches the twelve most frequent submucosal tumor types were chosen for description of their classification. The factors that indicate whether tumors are benign or malignant are mainly size and number of mitotic counts. Gastrointestinal stromal tumors are defined mainly by their CD117 positivity. In the future, there should be no more confusion between gastrointestinal stromal tumors and other types of submucosal tumors.

采用***非线性有限元软件,对试件在激光点热源作用下动态微变形过程进行了数值模拟。通过激光反射放大系统测量了试件在激光点热源作用下的动态微变形过程。模拟值与实测值的结果表明:热应力和相变应力的共同作用使得试件产生微变形,最终试件的变形方向取决于热应变和相变共同作用的结果,朝向激光束或背向激光束。比较实验值和模拟值,发现变形的最大值相近,变形过程却略有不同。考虑到激光点热源作用下有限厚度的试件内,温度场分布出现的反常效应,即内部的温度大于边界温度,提出采用波动理论修正经典的热传导计算模型,可望有效地提高模拟过程的计算精度。结论为进一步研究薄板激光弯曲的变形机理及变形过程奠定了基础。

通过红外热像仪测温装置,对有限厚度试件在激光点热源作用下热作用区侧面温度分布进行实时测量。结果表明:对于小厚度的试件,材料内部温度分布与用傅立叶定律得到的结果完全相反,材料内部的温度高于边界温度。对比短脉冲激光作用下产生非傅立叶效应的条件,它们之间有很大差异,由此提出将实验中出现的非常规现象定义为泛傅立叶效应,认为它是由于热量传播到边界时发生反射、叠加等波动行为所致。

随着移动互联网的迅速发展,用户的触媒习惯也在逐渐发生改变,集碎片化和内容化于一体的移动短视频成为用户接受各类信息的主要载体。用户对优质内容的巨大需求及其时间碎片化现象的日趋明显,使短视频与短视频平台在有效传递信息及提升用户认知方面极具潜力;因此,本研究从企业广告内容的角度出发,旨在探讨企业广告内容特征对用户品牌认知的影响。本研究使用实证研究法,设计了两组组间实验,探讨了企业广告内容的关键特征(幽默和热情)与用户品牌认知之间的主效应关系;此外还将沉浸体验与卷入度纳入研究,探讨两者在主关系中是否具有中介作用与调节作用。通过对实验数据的分析,证实了企业广告内容关键特征对用户的品牌认知具有显著且直接的影响;实验1通过独立样本T检验证明了幽默特征与热情特征的广告内容分别对用户的品牌认知存在直接影响。此外通过实验2验证了沉浸体验在该关系中具有中介作用,即企业广告内容关键特征显著正向影响个体的沉浸体验,进而显著正向影响其品牌认知。但对调节作用的分析表明,卷入度在该关系中仅起到部分调节作用,即在热情特征对用户的品牌认知的影响中,卷入度具有显著的调节作用;但在幽默特征对用户品牌认知的影响中,卷入度不具有显著性,亦说明其不具有调节作用。

AIM: To assess the relationship between severity of gastroesophageal reflux disease and apnea-hypopnea index (AHI) as an indicator of the severity of obstructive sleep apnea. METHODS: Data of 57 patients with proven obstructive sleep apnea and gastroesophageal reflux disease were analyzed. Patients were divided into two groups according to severity of the sleep apnea: 'mild-moderate' (A)-AHI 5≥5-30, n=27, 'severe' (B)-AHI >30, n=30. All patients underwent apnea monitoring during the night, upper panendoscopy and were asked about typical reflux symptoms. RESULTS: All examined patients in both groups showed a significant overweight and there was a positive correlation between body mass index and the degree of sleep apnea (P = 0.0002). The occurence of erosive reflux disease was significantly higher in 'severe' group (P = 0.0001). Using a logistic regression analysis a positive correlation was found between the endoscopic severity of reflux disease and the AHI (P = 0.016). Forty-nine point five percent of the patients experienced the typical symptoms of reflux disease at least three times a week and there was no significant difference between the two groups. CONCLUSION: A positive correlation can be found between the severity of gastroesophageal reflux disease and obstructive sleep apnea.

In a previous research we have studied the effect of the stimulation of the retina, by pulsed LED’s light of different wavelength, on the spectral density of the alpha rhythms of the electroencephalogram [1] [2]. In conformity to our results and the recent discovery of a nonvisual pathway of light from the retina to the brain, we are induced to search for the effect of stimulation of the retina, with different wavelength, on the melatonin’s secretion. We have, therefore, stimulated the retina with blue LED’s light 470 nm and red LED’s light 650 nm, and measured the melatonin’s secretion in saliva by means of High Pressure Liquid Chromatography (HPLC). The results show that melatonin values are higher with long wavelength stimulation (red, 650 nm) to be confronted with short wavelength stimulation where the values are lower (blue, 470 nm), the difference being significant (***). Action spectrum of short wavelength, producing melatonin suppression, was already evidenced in vivo;it was also demonstrated that blue LED’s light differentially modulated cell’s survival and growth, inducing mitochondrial suppression in vitro. We speculate, therefore, that long wavelength light (red) produces photobiomodulation effect at the level of the retina and that this effect is the opposite of the effect produced by the short wavelength (blue). The molecular mechanism underlying both effects may be, we suppose, the activation (red) or depression (blue) of the mitochondrial cytochrome c oxidase activity at the level of the pool of the retina’s ganglion cells.
