Precision methods and devices for the diagnostics of cardiovascular diseases are the one of the main directions of modern technology development in the field of medical instrument making. However, at this stage of development there are a few overall devices that allow for the diagnostics of cardiac muscle with precise accuracy and without internal interference in the body. This study considers the methods for measurement of biopotentials from the surface of the human body by means of electrocardiographic nanosensors. The device developed in the laboratory No. 63 of the Institute of Non-Destructive Testing of the National Research Tomsk Polytechnic University, its parameters and main characteristics are considered. The article focuses on the use of more sensitive equipment for more detailed study of the human body. The results of measurements carried out by means of the developed device are given.

AbstractIn the Shuowen, one of the earliest comprehensive character dictionaries of ancient China, when discussing where the Chinese characters derive their structural components, Xu Shen proposed the dual constitutive principle of “adopting proximally from the human body, and distally from things around.” This dual emphasis of “body” and “things around” corresponds largely to the phenomenological issues of body or corporeality on the one hand, and lifeworld on the other. If we borrow Heidegger’s definition of Dasein as Being-in-the world, we can easily arrive at a reformulation of Xu Shen’s constitutive principle of the Chinese script as one that concerns “bodily Dasein.” By looking into various examples of script tokens we can further elaborate on how the Chinese make use not only of the body in general but various body parts, and how they differentiate their life world into material nature, living things, and a multifaceted world of equipment in forming a core basis of Chinese characters/components, upon which further symbolic manipulation such as “indication”, “phonetic borrowing”, semantic combination, and “annotative derivation”, etc. can be based. Finally, examples will be cited to show how in the Chinese scripts the human body (and its parts) might interact with other’s bodies (and their parts) or with “things around” (whether nature, living creatures, or artifacts) in various ways to cover the social, environmental, ritual, technical, economical, and even intellectual aspects of human experience. Bodily Dasein, so to speak, provides us with a new perspective of understanding and appreciating the entire scope of the Chinese script.

ABSTRACTHeight is rarely taken seriously by historians. Demographic and archaeological studies tend to explore height as a symptom of health and nutrition, rather than in its own right, and cultural studies of the human body barely study it at all. Its absence from the history of gender is surprising, given that it has historically been discussed within a highly gendered moral language. This paper therefore explores height through the lens of masculinity and focuses on the eighteenth century, when height took on a peculiar cultural significance in Britain. On the one hand, height could be associated with social status, political power and ‘polite’ refinement. On the other, it could connote ambition, militarism, despotism, foreignness and even castration. The article explores these themes through a case-study of John Montagu, earl of Sandwich, who was famously tall and was frequently caricatured as such. As well as exploring representations of the body, the paper also considers corporeal experiences and biometric realities of male height. It argues that histories of masculinity should study both representations of gender and their physical manifestations.

Ayurveda has described three basic physiological constituents of the human body, viz., Dosha, Dhatu and Mala. In Ayurvedic Science, the one who has balanced Doshas, balanced Agni, properly formed Dhatus, proper elimina- tion of Malas, well-functioning of bodily processes and whose mind, soul, senses are full of bliss is called a healthy person1. So, the formation of Dhatu is also a good indicator of good health there are seven Dhatus ex- plained in Samhitas, those are Rasa, Rakta, Mamsa, Meda, Ashti, Majja and Shukra among all Dhatus, Shukra is considered as the sara of all other Dhatus2. Shukra Dhatu is one of the seven Dhatus in the body and Shukra is white, pure, excellent Dhatu, which is considered as best among all seven Dhatus. According to many Acharyas of Ayurveda, Garbhotpadana (reproduction) is the chief function of Shukra Dhatu, and the important fact is Shukra Dhatu also shows its effect all over the body in the form of Shukradhatusarata because Shukradhatuis located in the entire body. Sperm along with spermatic fluid and male sex hormones are also one part of Shukra Dhatu. Anu Shukra Dhatu (primordial germ cell) is essential for the Shukra Dhatu (Testosterone, Estrogen). Vi- tiation of Shukra dhatu shows Shukra dhatudusti (pathology) in the form of Vriddhi (hyper state) or Kshaya (wan- ing). This vitiation may lead to main infertility and many other physical as well as psychological disorders. All Dhatus have their definite locations in the body; they are present in every cell in subtle form. Every cell possesses the capacity to divide or reproduce itself. Thus, one has to interpret the Garbhotpadana (reproduction) function of Shukra Dhatu. In future, it may be achievable that with the development of the facts; we will discover any content in the cell whichpossesses a definite role in cell division.Sperms along with spermatic fluid and male sex hor- mones are also one Partofshukra, parallel to which females possess Artava. Stri-Shukra excreted during coitus is nothing but the secretions of bartholins, cervical and endometrial glands emergence at theendoforgasm.

Currently, in various industries (engineering, aircraft, energy, etc.) the issue of product quality assurance and control is particularly acute. This is due primarily to the ever-increasing requirements for increasing reliability with increasing loads on products, which entails the strengthening of technical standards. The issue of quality control for rocket and space technology products is especially relevant. Modern power structures of rocket and spacecraft made of polymer composite materials, and especially the body of solid fuel rocket engines (SFRЕ), are multilayer packages of various polymer-composite materials (PKM), obtained and interconnected in the process of manufacturing the body. The efficiency of SFRЕ depends on the quality of the formation of PKM in production conditions. The most important issues are the implementation of production quality control of composite structures, the reliability of control results and the ability to automate the control process. The article presents an automated system of non-contact ultrasonic non-destructive testing, which allows to control the stability of the technological process of forming the composite material of the wall of the SFRЕ body and, if necessary, to adjust it. The probability of detecting zones of anomalous violation of the integrity of the wall material of the SFRЕ housing is carried out due to adaptive algorithms, digital systems of multilevel matrix processing and optimal filtering of the received signals. The automated system of contactless ultrasonic non-destructive quality control of SFRЕ cases allows to register conditions of scanning and control for more visual representation of the defectogram in the expanded look of the case of a product in the course of control and at documentation of its results. The presented results of work on the development of an automated system of non-destructive testing of the integrity of the buildings of the SFRЕ type "cocoon" confirm the possibilities of practical implementation in production.

The paper reports on two specific research activities devoted on the one hand to detailed finite element simulations of glued timber beams with emphases on random nature of the modulus of elasticity and, on the other hand, to destructive testing of a set four glued timber beams having structural dimensions. While the stochastic simulations were founded on the knowledge of probability density distributions of the modulus of elasticity acquired from non-destructive testing of local moduli from 3600 regularly spaced indentation measurements, the destructive testing of beams in four-point bending aimed at providing information to be used a-posteriori in improving the original predictions in the framework of Bayesian statistics. In this regard the non-destructive testing together with stochastic simulations of beam deflections is assumed to provide prior information to be updated in the second Bayesian step. This, however, will be discussed elsewhere so that only necessary prerequisites are mentioned here.

The human being in the environments of modern technology has to endure stresses of many and varied kinds of vibrations [1]. Measuring vibration is an important tool in rehabilitation and biomechanical fields of research. We have proposed image processing as a new method to record and determine the frequency response of human body. The subjects were exposed to whole body periodical vibration while standing on a shaking table. Two digital camcorders were used to capture the motion of colored pencil-dot markers on the skin of human body (forehead) and on the edge of the shaking table. After color spotting each frame, the binary image results were processed using new circle factor criteria proposed in this work, for fast finding circles based on second order statistics. The extracted points were calibrated using our own extended version of the direct linear transformation (DLT) method. We subsequently used Borland Delphi 5.0 language to develop useful software for measuring and analyzing human body vibration. As a result, it was clear that the proposed method was lower noise-sensitive in comparison to accelerometer. In order to investigate the validity of the software, the obtained mechanical impedance of the body were compared with other investigations in literature and showed to be compatible. The main advantage of this method is working with a simple user-familiar hardware with no external device attached to the subject and also a user-friendly-software.

Properties of light-weight concrete congaing lightweight expanded clay aggregate differ from the ones of normal-weight concrete containing natural normal-weight aggregate. Particularly, when compared with natural normal-weight aggregate, these differences are due to lightweight aggregate being characterized by significantly lower strength and bulk weight as well as higher absorptivity. Properties of expanded clay lightweight aggregate influence the ones of light-weight concrete, too. Parameters obtained by means of Schmidt impact hammer non-destructive testing are influenced by series of factors, among others also concrete moisture. Moisture of light-weight concrete containing lightweight aggregate influences rebound number of Schmidt impact hammer. As to Schmidt impact hammer type N (2.25 Nm impact energy), rebound number on dry concrete exceeds the one on waterlogged concrete by 21 %. Correction coefficients for rebound number correction were defined taking into account moisture of light-weight concrete under testing.

The skin, which is the largest part  of the human body, is the body's first defense against bacterial and virus attacks. When the skin is exposed to the sun, dry weather, or bacteria, the reaction will spread to other parts of the body, and can even result in death if it is too late to be handled especially if the sufferers are children who are very vulnerable to disease. In this study an expert system was implemented to diagnose skin diseases in infants using the certainty factor method. certainty factor method is very suitable for expert systems that diagnose something that is uncertain. This system makes a diagnosis based on the symptoms felt by the user and then calculates certainty factors based on existing symptoms. Based on the test results by making comparisons between manual calculations and the one carried out by the system it is known that 90.22% of the diagnosis results get the same results so that the system is said to be suitable for use.

Non-destructive tests were conducted on welded fatigue specimens prepared using the same steel material and welding method as the one used in the manufacture and repair procedures of a KRUPP SchRs 600 bucket wheel excavator to reveal any defects present. The chemical composition, the mechanical properties, tendency to cracks and the microstructure of the bucket wheel material were determined using appropriate tests. The initiation of cracks and their subsequent growth during fatigue testing of the welded specimens was studied using ultrasound testing (UT) and a metallographic examination in order to investigate the causes of failure during service and predict fatigue life of the bucket wheel welded parts. It was found that the welding method used produces welds with numerous discontinuities that can only be detected using ultrasound techniques.
