The present study aims to identify the peculiarities of constitutional changes of some skeletal dimensions, which determine the shape and sex-linked traits of the body type of urban schoolchildren during puberty.The anthropometric data presented were collected by the author of the article during anthropometric measurement carried out annually in Minsk (between 1982 and 1991) mostly among the same schoolchildren, aged 7 to 17.The different body type (somatotypes) are determined and classified according to a scheme of somatotyping developed by Belarusian anthropologists (Salivon, Polina, 2003). The determination of somatotypes is based on the combined evaluation of five anthropometric indices, which describe the degree of skeleton massiveness and level of subcutaneous fat deposition in the body and the extremities. Two contrasting somatotype variants are distinguished – asthenized leptosomic and adipose hypersomic, as well as mezosomic and four intermediate types with varying degree of leptosomy or hypersomy. The comparative analysis of sex- and age-related variability in body length, chest circumference, shoulder breadth (bisacromial diameter) and maximum pelvic width (biacromial diameter) revealed the wave-like nature of body development process with alternating acceleration and deceleration of body dimensions growth. The constitutional peculiarities based on the development of bone formation are reflected in different time periods and rates of acceleration in annual indices increase. The growth process acceleration begins about one year earlier in hypersomic schoolchildren. On the contrary, it is delayed in leptosomic schoolchildren. Mezosomic children and adolescents have a more balanced body development with a reduced number of alternating minimum and maximum increases in the considered body dimensions.
本研究旨在确定某些骨骼尺寸的结构变化的特殊性,这些骨骼尺寸决定了青春期城市学童的体型和性别相关特征。本文作者所提供的人体测量数据是在1982年至1991年期间每年在明斯克进行的人体测量中收集的,主要是在7至17岁的同一学童中收集的。根据白俄罗斯人类学家制定的躯体分型方案(Salivon, Polina, 2003)确定和分类不同的体型(躯体分型)。体型的确定是基于五种人体测量指标的综合评估,这些指标描述了骨骼质量的程度和身体和四肢皮下脂肪沉积的水平。两种截然不同的体型变体被区分开来——衰弱型瘦体和脂肪型高体,以及中体细胞和四种不同程度的瘦体或高体的中间型。对体长、胸围、肩宽(双峰直径)和最大骨盆宽度(双峰直径)的性别和年龄相关变异性的比较分析揭示了身体发育过程的波浪式性质,身体尺寸生长交替加速和减速。基于骨形成发展的体质特征反映在不同的时间段和年指数的加速率增加。生长过程的加速在高体发育学童中大约早一年开始。相反,在患有纤体病的学龄儿童中,这种发育会延迟。同染色体儿童和青少年的身体发育更为平衡,所考虑的身体尺寸的最小和最大交替增加的数量减少。

The Laboratory of Anthropological Reconstruction (LAR) of the Centerfor Physical Anthropology (CPhA) of the Institute of Ethnology and Anthropology of the Russian Academy of Sciences has a truly unique collection of graphic and sculptural portraits made from the skulls of ancient and modern Eskimos from the Old and New Worlds. The article presents the works of G.V. Lebedinskaya, T.S. Surnina, T.S. Baluyeva, as well as some reconstructions made more recently by todays LAR research fellows. These latest works were carried out, taking into account the new data based on the improvement of the method of graphic facial reconstruction from a skull. The processing technique for 3D reconstruction of skull, based on a series of photographs taken from different angles is described. Thanks to this method, it is possible to obtain accurate images of the skull from front and side profile without any perspective distortion. The presented recon-structions were made using both classical and new methods, the last ones, based on the use of computer and the Photoshop Software. An innovative way of rep-resenting lifelike facial features makes it possible to show the real color of the skin, hair and eyes. In the article is as well discussed the place of the Eskimos in the anthropological classification system and the peculiarities of their features in Greenland and Chukotka.

A method is proposed for monitoring the natural frequencies of hydro power plant dams using continuous seismic observation data. The object of the research is the largest in Russia arched Chirkey dam located in the Caucasus. At the initial stage, a detailed study of the natural oscillations of the dam was performed using the method of coherent restoration of the standing wave fields with the definition of both the natural frequencies of the structure and their modes. The features of seasonal changes in the total field of standing waves are studied and factors affecting changes in natural frequencies are established. At the next stage, the values of natural frequencies were determined from the spectra of microseismic oscillations recorded by seismic equipment installed on the object. Observation points located in the antinodes ofstanding waves were used. The values of the natural frequencies of the Chirkey dam, as a whole, decrease with increasing upstream level. It was determined that there are additional factors leading to the hysteresis effect in the relationship between the values of the upstream level and natural frequencies, presumably associated with relaxation processes in the dam body and/or in the dam-base system after the change of level. A method for monitoring the state of the dam is proposed, based on a comparison of the observed values of natural frequencies with the predicted ones. The latter are determined by linear dependencies on the upstream level, taking into account the time shifts associated with relaxation processes
提出了一种利用连续地震观测数据监测水电站大坝固有频率的方法。研究对象是位于高加索地区的俄罗斯最大的奇基拱坝。在初始阶段,使用驻波场的相干恢复方法对大坝的固有振荡进行了详细研究,并定义了结构的固有频率及其模式。研究了驻波总场的季节变化特征,建立了影响驻波固有频率变化的因素。在下一阶段,根据安装在物体上的地震设备记录的微震振荡频谱来确定固有频率的值。使用了位于驻波波腹的观测点。Chirkey大坝的固有频率值,作为一个整体,随着上游水位的增加而降低。已经确定,在上游水位值和固有频率之间的关系中,还有其他因素导致滞后效应,可能与水位变化后坝体和/或坝基系统中的松弛过程有关。在对大坝固有频率观测值与预测值进行比较的基础上,提出了一种监测大坝状态的方法。后者是由上游水平的线性依赖性决定的,考虑到与弛豫过程相关的时间偏移

Lg-coda Q in the central part of the East European platform from small aperture array “Mikhnevo” data 来自小孔径阵列“Mikhnevo”数据的东欧平台中部的Lg尾波Q
Pub Date : 2019-12-16 DOI: 10.35540/2686-7907.2019.1.05
Whereas the quality factor Q is one of the basic parameters required in seismic hazard estimation, no systematic studies of seismic attenuation factors have been carried out in the central part of the East European Platform due to the lack of a dense seismic network and a small number of regional earthquakes. The main part of the events, recorded by the small aperture array “Mikhnevo” 80 km to the south of Moscow, consists of industrial explosions of different magnitude. The idea of the paper is to apply conventional seismic methods to the analysis of seismic waveforms of industrial explosions. The paper focuses on the Lg coda of the quarry blast in “Mikhailovsky” quarry 300 km from the array. Vertical components of the short-period and broad band records of the sensors positioned in the well at the depth 20 m are processed according to the SSR algorithm, suggested by Xie and Nuttli, 1988, and extensively used by Mitchell et al in different regions of the world. The advantages of the method imply exclusion of the source and site characteristics by taking spectral ratios of the successive time windows of the coda. Compared to the earthquake waveforms, the Lg coda of explosions is shorter, less regular and contains higher frequencies. The length of coda varies according to the noise level. We selected 14 events from the same quarry in different years, which demonstrate remarkable stability of the waveforms. All the events were processed individually to obtain the frequency dependence of Q in the form Q(f)=Q0 f , where Q0 is the Q factor at the frequency 1 Hz and  is the power. To produce stable estimates of Q0 and  individual values were averaged for frequency bands: 2-6 Hz, 2-7 Hz, 3-6 Hz, 3-7 Hz for different length of coda. The preferable frequency range for Lg coda Q studies of quarry blasts is suggested as 3-6 Hz, which avoids instability of coda in 1-3 Hz interval, presumably caused by local site effect, connected with the 3 km thick sedimentary layer. The Q estimate of Q0=584±89, =0.41±0.06 proves considerable heterogeneity of the upper crust in the region. Speaking about Q factor as an indicator of the tectonic activity, the studied area can be related to a region of moderate activity.
尽管质量因子Q是地震危险性估计所需的基本参数之一,但由于缺乏密集的地震网络和少量的区域地震,东欧平台中部尚未对地震衰减因子进行系统研究。莫斯科以南80公里处的小孔径阵列“Mikhnevo”记录的事件的主要部分包括不同规模的工业爆炸。本文的思想是将传统的地震方法应用于工业爆炸的地震波形分析。本文重点研究了距离阵列300公里的“米哈伊洛夫斯基”采石场爆破的Lg尾波。根据Xie和Nuttli,1988提出的SSR算法,对位于20m深井中的传感器的短周期和宽带记录的垂直分量进行处理,Mitchell等人在世界不同地区广泛使用该算法。该方法的优点是通过取尾波连续时间窗的谱比来排除源和位置特征。与地震波形相比,爆炸的Lg尾波更短,不那么规则,并且包含更高的频率。尾波的长度根据噪声水平而变化。我们在不同年份从同一采石场选取了14个事件,这些事件表明了波形的显著稳定性。单独处理所有事件以获得Q的频率依赖性,形式为Q(f)=Q0f, 其中Q0是频率为1Hz时的Q因子 就是力量。产生Q0和 对不同尾段长度的2-6赫兹、2-7赫兹、3-6赫兹、3-7赫兹频带的个体值进行平均。采石场爆破的Lg尾波Q研究的优选频率范围为3-6 Hz,这避免了尾波在1-3 Hz间隔内的不稳定,可能是由局部场地效应引起的,与3 km厚的沉积层有关。Q估计值Q0=584±89,=0.41±0.06证明了该地区上地壳具有相当大的非均质性。将Q因子作为构造活动的一个指标,研究区可能与中等活动区有关。
