This research was to observe patients,who underwent orthodontic tooth alignment correction with dental brackets,for the purpose of early detection of white spots(early satge of caries)and dynamic measurement of distance between teeth edges based on the digital photographs taken with a smartphone Sony Xperia *** reading was realized taking into account the adjustment of color features of a standard ceramic surface(tile)that was selected during the dental brackets installation period,the photo of which was taken simultaneously during the dynamic observation *** color scale RGB was transformed into CIE L*a*b scale of color measurement with regard to the correction of RGB components of image by usage of correction coefficient for calibration tile surface RGB *** expert appraisal showed sensitivity of proposed method was between 88.7%and 96.2%(the mean 93.1%)and specificity between 68.4%and 84.2%(the mean 75.4%).The positive predictive value was between 89.5%and94.0%(the mean 91.5%);and the negative predictive value was between 72.7%and 86.7%(the mean 80.6%).The measurement of the distance between teeth edges during the first 10 days following the brackets installation was carried out using a self-scalable ruler that was calibrated,according to the standard sizes of the dental bracket system *** Android application of self-scalable ruler was developed using *** development of a pronounced pain syndrome was observed when the velocity of distance changes between teeth edges was rather high-0.051+0.004 mm/*** improvement of efficiency of the suggested method is expected due to application of illumination standards during the shooting period.

The critical current density(Jc)of the body centered cubic(bcc)V0.6Ti0.4 alloy enhances significantly after the addition of rare earth Gd as the latter is immiscible in the matrix[***,***,IEEE ***.31,5(2021)].Very low solubility of Gd in other bcc elements like Ta and Nb is also well known[*** Gschneidner in Prog Sci Technol Rare Earths,vol.1,pp.222–258,1964&M Neuberger,*** in Handbook of Electronic Materials,Vol 4,1972].We use these facts to find the effect of adding 1 at.%Gd into the Nb0.6Ti0.4 and Ta0.4Ti0.6 alloys on the superconducting properties e.g.,the transition temperature(Tc),Jc,flux pinning force density(Fp)and the *** spite of Gd being ferromagnetic,the Tc in these alloys change only marginally(increase by 0.3 K in Ta0.4Ti0.6 and decrease by 0.15 K in Nb0.6Ti0.4 after Gd *** Jc(H?1 T,T=4 K)increases by 5 and 1.5 times respectively in the Gd containing Nb0.6Ti0.4 and Ta0.4Ti0.6 alloys,which is quite small as compared to the increase observed in the V0.6Ti0.4(20 times)*** Gd addition,the grain size reduces approximately by 65%and 10%respectively in Nb0.6Ti0.4 and *** analysis indicates that grain boundaries are the major flux line pinning centres in these alloys and the role of Gd in increasing the Jc depends on the effectiveness of Gd in reducing the grain *** grain boundary density depends strongly on the distribution of Gd precipitates,which is quite different from each other for two alloy systems under ***,our results suggest that the addition of Gd to commercial Nb‐Ti(Nb0.37Ti0.63)alloy is a new promising route for achieving higher Jc values.

AIM:To compare the response to skin prick tests (SPTs) to food antigens (FAs) and inhalant allergens (IAs) in patients with two subtypes of irritable bowel syndrome (IBS) and healthy controls. METHODS:We compared the results of SPTs for IAs and FAs in 87 volunteers divided into three groups:diarrhea predominant IBS (D-IBS) GroupⅠ(n = 19), constipation predominant IBS (C-IBS) Group Ⅱ (n = 17), and normal controls Group Ⅲ (n = 51). RESULTS:Of the 285 tests (171 for FAs and 114 for IAs) performed in GroupⅠwe obtained 45 (26.3%) positive responses for FA and 23 (20.1%) for IA. Of the 153 tests for FA in Group Ⅱ, we obtained 66 (20.1%) positive responses, and of the 102 tests for IA, we obtained 20 (19.6%) positive responses. Of the 459 tests for FA performed in Group Ⅲ, we obtained 39 (84%) positive responses, and of the 306 for IA, we obtained 52 (16.9%) positive responses. The numbers of positive responses were not significantly different between the three groups, but in the D-IBS group, the number of SPTFA responses differed significantly from those for the other two groups (P < 0.01). CONCLUSION:Despite the small number of cases studied, the higher reactivity to FAs in GroupⅠcompared to Groups Ⅱ and Ⅲ adds new information, and suggests the presence of a possible alteration in intestinal epithelial function.

介绍了莺—琼盆地几种主要储层类型的特征及分布，包括：近源、远源、低位三角洲，浊积扇，浊积水道，海滩，水下高地浅滩，风暴席状砂和潮流砂脊等。通过对相对海平面变化及层序分析，确定了本区的旋回系统，认为本区第三纪经历了３次较大的海平面下降过程，盆地的沉积、沉降中心也有过几次较大的迁移，为在盆地中发育储层及储盖组合创造了有利的条件，分别对应于Ｓ４０、Ｓ６０和Ｓ７０层序界面，这些层位应是储层比较发育的层段。还分析了压实、胶结、溶蚀等成岩作用对储层物性的影响。结果认为：盆地及盆地周缘的构造运动和环境条件适合形成多种类型的储集体；沉积、成岩条件有利于储层孔隙的保存和发育；本区完全具备形成大气区的储层条件。
