The article considers a possible improvement of road vehicle safety by using eCall – a system which initiates an emergency call in case of traffic accident. A possible way of better description of a frontal impact accident of a vehicle is examined and enriched by the information from the onboard e-call unit. In this article, we analyze results of frontal crash tests with different types of barriers and overlapping area and look for the correlation between the individual vehicle and collision parameters in order to provide a better description of the severity of the accident by the eCall system. The relation among the selected parameters is described using the correlation analysis.

With the popularization of passenger vehicle safety devices such as safety belt, airbag and so on, the chance that occupant’s upper limbs were injured seriously was decreased significantly in frontal impact. However, the injury of occupant’s lower limbs became more and more severe, especially on lower leg injury. 37 groups of test data of China NCAP crash tests including full-frontal rigid crash and 40% offset deformable barrier crash were investigated in this paper, and lower leg injury distributing characteristic of drivers and passengers in these two kinds of crash configurations were obtained. Finally the effect rules of characteristic parameters on lower leg injury were summarized.

An analysis of the lower extremity responses in various frontal impact test configurations was performed. The THOR-LX anthropomorphic test device (ATD) representing a mid-size adult male was used. Four groups of frontal crash test data were analyzed. These groups included: Rigid Fixed Barrier (RFB), Moderate Overlap Offset Deformable Barrier (ODB), Small Overlap Rigid Barrier (SORB), and Oblique Impact (OI) crash tests.. This analysis indicated that the lower extremity responses could be high especially in the oblique impact and small overlap crash tests. This study focused on understanding the causes of the resulting high responses. ATD lower extremity kinematics and interaction with intruded body structure and/or instrument panel varied in the different frontal impact configurations. Therefore, the dominant causes of lower extremity responses in terms of tibia forces and moments were not the same for all frontal crash modes. Maximum Tibia Index results associated with the four groups of frontal impact tests were used to develop a better understanding of ATD kinematics and response mechanisms of the lower extremities. The contact sequence of the lower leg to vehicle interior components was illustrated for OI. This paper investigated the cause of lower extremity responses in these crash tests. Analysis indicated that the time at which maximum intrusion occurs did not necessarily coincide with the time of maximum lower extremity responses expressed by the Tibia Index.

We are experiencing rapid progress in all types of imaging techniques used in the detection of various numbers and types of mutation. In situ hybridization (ISH) is the primary technique for the discovery of mutation agents, which are presented in a variety of cells. The ability of DNA to complementary bind is one of the main principles in every method used in ISH. From the first use of in situ techniques, scientists paid attention to the improvement of the probe design and detection, to enhance the fluorescent signal intensity and inhibition of cross-hybrid presence. This article discusses the individual types and modifications, and is focused on explaining the principles and limitations of ISH division on different types of probes. The article describes a design of probes for individual types of in situ hybridization (ISH), as well as the gradual combination of several laboratory procedures to achieve the highest possible sensitivity and to prevent undesirable events accompanying hybridization. The article also informs about applications of the methodology, in practice and in research, to detect cell to cell communication and principles of gene silencing, process of oncogenesis, and many other unknown processes taking place in organisms at the DNA/RNA level.

In this paper, various methodologies of acoustic and language models, as well as labeling methods for automatic speech recognition for spoken dialogues in emergency call centers were investigated and comparatively analyzed. Because of the fact that dialogue speech in call centers has specific context and noisy, emotional environments, available speech recognition systems show poor performance. Therefore, in order to accurately recognize dialogue speeches, the main modules of speech recognition systems—language models and acoustic training methodologies—as well as symmetric data labeling approaches have been investigated and analyzed. To find an effective acoustic model for dialogue data, different types of Gaussian Mixture Model/Hidden Markov Model (GMM/HMM) and Deep Neural Network/Hidden Markov Model (DNN/HMM) methodologies were trained and compared. Additionally, effective language models for dialogue systems were defined based on extrinsic and intrinsic methods. Lastly, our suggested data labeling approaches with spelling correction are compared with common labeling methods resulting in outperforming the other methods with a notable percentage. Based on the results of the experiments, we determined that DNN/HMM for an acoustic model, trigram with Kneser–Ney discounting for a language model and using spelling correction before training data for a labeling method are effective configurations for dialogue speech recognition in emergency call centers. It should be noted that this research was conducted with two different types of datasets collected from emergency calls: the Dialogue dataset (27 h), which encapsulates call agents’ speech, and the Summary dataset (53 h), which contains voiced summaries of those dialogues describing emergency cases. Even though the speech taken from the emergency call center is in the Azerbaijani language, which belongs to the Turkic group of languages, our approaches are not tightly connected to specific language features. Hence, it is anticipated that suggested approaches can be applied to the other languages of the same group.

In the introduction to his readings in political philosophy, Professor Coker says, “since the time of Plato there has been, in every philosophic age, some inquiry as to the justification of political organization in general, as to the relative merits of different political forms, and as to the appropriate position and privileges of the individual as master, member, or subject of the political order of society. Why do we have political organization? What in our present condition do we owe to it? What future benefits may we properly expect to derive from it? Are its purposes characteristically manifold and changing, or are they ultimately reducible to a few limited objects or to some single end? What is its best form? Who should control it? What is its proper relation to the ideas and sentiments of the community at its basis? What spheres of individual and social life is it incompetent to enter? Philosophers and publicists of various types have sought to answer these questions in abstract terms.”If an analysis be made of the questions with which political thought has been concerned, it is found that emphasis was placed at various periods upon widely different types of problems. In the medieval period political controversy centered in the contest for supremacy between spiritual and temporal authorities; in the seventeenth and eighteenth centuries, the dominant interest was in the contest between monarchic and democratic theories of political organization; at present, the extent of state activities has come into prominence, and the connection between political and economic interests is especially close. Besides, political conditions have changed so greatly from age to age that the same problem had quite different meanings at different periods.

The article is devoted to the study of pragmatic aspects of the use of phraseology in the textual space of Carlos Ruiz Safón’s novel «Prisoner of Heaven». One of the defining features of the individual style of this well-known modern Spanish writer is the metaphoricity and figuration of aristic expression, the saturation of the text with phraseological units that play a significant role in creating a pragmatic charge of the work of art. Along with general linguistic phraseological units, which include commonly-used vocabulary, the author uses dialectal and authorial phraseological units, which is a feature of his individual style. All three designated groups of phraseological units mostly reflect the negative psychophysical and emotional state of the characters. The author uses dialectal, individually-authorial and modified phraseological units, which is a feature of his individual style. It is determined that transformation is one of the most productive and most effective ways to update linguistic means in works of art. Author’s modification of FU leads to a change in the semantics and structure of expression, gives it a more expressive or emotional coloring. Transformed phraseology is limited to individual usage and is subject to the context of the work. Modified FUs in the Zafón’s artistic space acquire certain aesthetic and artistic qualities. Their modification is mainly to create the desired stylistic effect – to achieve emotional or expressive expression, which increases the reader’s interest, focuses on the content, issues of the work, as well as reveals the potential expressive potential of the Spanish language. In the transformed FUs, not just a new meaning is traced, but a combination of the well-known and the occasional. The unique combination of different types of phraseological units in the novel is considered a manifestation of individual style and makes a representation of the individually-authorial linguistic picture of the world more expressive.

Survey Questionnaires

Introduction: Retainers are used after all orthodontic treatment, to prevent or minimize relapse and recurrence. Among various retainers used, Hawley retainer and ‘invisible’ retainers are the most common. Most of the orthodontists favored permanent retention. It is obvious that the retention procedures are variable and depended largely on personal preferences, and there does not seem to be any consistent pattern in the application of retention methodologies. The  purpose of this study was to survey the retention protocols among orthodontists in Nepal. Materials and Method: The complete lists of the names and addresses of orthodontists in Nepal was obtained from the ODOAN. The questionnaire was sent to them which consisted of multiple-choice questions and short answer, related to background information of the individual orthodontist, retention use in general, the frequency of different types of bonded or removable retainers that are used, the retention protocol, the type of retainer used in specific situation. All statistical analyses were performed using the Statistical Package for Social Sciences (SPSS), version 12.0.1 (SPSS Inc, Chicago, Illinois, USA) Result: The survey questionnaires were completed by 90.42% of the 94 orthodontists of Nepal, 58.8% males and 41.2% females with a mean age of 36.7 years. Most of the orthodontists used a clear (vacuum) retainer (80%) in the maxilla and fixed bonded retainer in the mandible. Most of them prefer the use of retainer for a continuous 24 hours except during eating and brushing for 6 months to 1 year (56.5%) and if possible, for 1 to 2 years (28.2%). Conclusion: Majority of Nepalese orthodontists provide vacuum formed retainer on maxillary arch and bonded retainer in mandibular arch. There is no specific consensus on other type of retainers, duration of wear and follow up visits which is affected by various other factors.

The present paper presents a study of square-section tubes conditioned to a FE dynamic frontal impact analysis, considering a 10.0 m/s initial velocity against an infinitely rigid plane. A 50.0 kg punctual mass is positioned on center of the cross-sections, on the farthest side from the rigid plane and the deceleration pulse is measured along the simulations. After validating the numerical model with analytical solutions, the results are compared for four geometries with little structural differences in order to access the role of each difference on the geometry under crash situations. The results show that adding many triggers to the geometry may not be the best performance solution for crash boxes, since the geometry with few triggers achieved better values of deceleration peak than the others. In addition, the presence of holes showed to be an instability cause to the system. The structural solutions presented could be of great value for future vehicle crash box developments.

Work related fall from height many a times causes fatal injuries and death amongst working in various construction sites. It leads to different types of fatal bodily injuries including spinal injuries causing economic burden to the family. Although, they have been provided with protective gears and proper training for its use; it has been observed that workers are not using these in a proper ways. They eventually met with accidents which can easily be prevented. Accidental compression of neck by safety harness following fall from height has rarely been described leading to death of the individual. A case was brought for autopsy following accidental compression of neck structure causing fracture of cervical spine and transaction of spinal cord. In this paper, the case has been described with its autopsy findings.
