Decrease in coal losses during mining of contiguous seams in the near-bottom part at Vorkuta deposit

The problem of formation of extended zones with high rock pressure (HRP) from safety pillars at the boundaries of extraction pillars formed due to the mine layout of complex geometry is considered at the example of JSC Vorkutaugol mines. A detailed analysis of the remaining reserves of the near-bottom part of the deposit was carried out to estimate losses and the impact of HRP zones from the Chetvertyi protective seam to mining operations on the Troinoi upper seam along with the possibilities for the reduction of sizes of HRP zones at the account of expanding the underworked space. Due to research on the near-bottom part of the Vorkuta deposit, within the framework of the accepted layout, a zone at the Komsomolskaya mine and two zones at the Zapolyarnaya-2 mine were singled out, at which losses at the boundaries of the extraction pillars amount up to 13-22 % of the total resources of the mine field. The high volume of losses in these pillars indicates the relevance of research on the priority extraction impact of protective seams on the efficiency and safety of mining operations in the working area of underworked and HRP zones. Based on the analysis of foreign and Russian experience in the pillar cleaning-up at the boundaries of working areas and the methodical guidelines and instructions, a technological scheme was developed that allows increasing the coal mining recovery factor in the near-bottom part of the Vorkuta deposit from 0.75 to 0.9 without fundamental changing of the ventilation and transport networks and also without purchasing any additional mining equipment. The conducted economic calculations confirmed the effectiveness of implementing the new technological scheme for cleaning-up reserves at the boundaries of extraction districts. The economic effect is from 0.079 to1.381 billion rubles of additional profit from coaxial extraction pillars, depending on the mining and geological conditions and the size of the pillars

Real-Time Water Quality Monitoring with Chemical Sensors

Water quality is one of the most critical indicators of environmental pollution and it affects all of us. Water contamination can be accidental or intentional and the consequences are drastic unless the appropriate measures are adopted on the spot. This review provides a critical assessment of the applicability of various technologies for real-time water quality monitoring, focusing on those that have been reportedly tested in real-life scenarios. Specifically, the performance of sensors based on molecularly imprinted polymers is evaluated in detail, also giving insights into their principle of operation, stability in real on-site applications and mass production options. Such characteristics as sensing range and limit of detection are given for the most promising systems, that were verified outside of laboratory conditions. Then, novel trends of using microwave spectroscopy and chemical materials integration for achieving a higher sensitivity to and selectivity of pollutants in water are described

Gender Inequality in Social Security on the Basis of the ECtHR Case-Law

As the European case-law shows, nowadays, there are numerous problems in the social sphere. Accordingly, there appears to be a need to study international regulation of equality and current social security problems to find possible solutions to the existing shortcomings and to strengthen human rights protection. The article aims to analyse the universal international regulation of equality and gender equality, in particular, and to study the problems of gender inequality in social security based on the European Court of Human Rights (ECtHR) case law to eliminate this discrimination. The leading research method is a legalistic one. It allowed us to analyse the international legislation on gender equality and to look into the ECtHR case law in gender discrimination in social security. It was found that gender inequality in social security is often a result of prior gender-based discrimination in labour relations. Despite the fact that legal acts protect women in cases of inequality, the analysis of the ECtHR case-law permitted us to conclude that men suffer from gender discrimination as much as women. Therefore, it is suggested to adopt legal acts on the equality of men and women in social security to overcome such discriminative practices at the legislative level. It is also recommended to implement the governmental policy on counteracting gender stereotypes in society. The research results can improve national legislation and international legal acts, further research into equality issues, and develop a methodological base for teaching human rights and social security

Batch drying in sintering

An adapted mathematical model of sintering permits analysis of the thermophysical characteristics of batch drying, primarily in the main sintering period. Over the whole length of the sintering machine, most of the bed volume corresponds to equilibrium moisture content, which may be higher or lower than the initial value. The temperature of the gas entering the drying zone is calculated, and its dependence on the parameters of the batch and gas is determined. © 2013 Allerton Press, Inc

Today, Ukraine is at the stage of forming a social and civil society. The main direction of state activity in the field of reforming Ukraine is the study, analysis and reform of the existing system of social services. The purpose of the study is to substantiate and summarise the main directions for the development of the system of financing social protection; to consider concepts such as “social protection”, “social insurance” and “social assistance”. To form and generalise knowledge about the existing system of financial and legal relations between the state and the population. To reveal the peculiarities of financing and directions of budget use in state and non-state social funds in a market economy. During the writing of the article, specific and general scientific methods of cognition were used to study and analyse the proposed topic. The method of generalisation, synthesis and analysis, observation, comparison and the method of scientific abstraction were used to evaluate and study the system of social funds in Ukraine. The system of social services in Ukraine was analysed. The existing system was analysed, weak points were revealed. Information on the foreign experience of developed countries in the field of providing social services to the population was considered. The current normative legal acts and laws were considered. Recommendations for the introduction of foreign experience in the existing system of social services have been developed. The study and analysis of the financing and functioning of the system of social protection and assistance to citizens provide an opportunity to understand how effectively it works. Assessing the effectiveness of state and non-state social funds should help identify weaknesses in the system and suggest a number of actions to improve their performance

CLINICO-BIOENERGETIC RATIONALE FOR THE USE OF PHYTOTHERAPY IN PATIENTS WITH TRAUMATIC BRAIN DISEASE AND ARTHRITIS ACCOMPANIED BY AUTONOMIC DISORDERS

The subject of the study is the establishment of the value of the effectiveness of the application of a complex of phytosbores obtained with the help of bioenergetic technologies in patients with vegetative disorders that aggravate the course of the underlying disease during the planned course of rehabilitation. For this purpose, 97 patients with traumatic brain disease and rheumatoid arthritis with vegetative disorders were examined. All examined were divided into 2 groups: the main group consisted of 64 patients, in the complex rehabilitation of which, along with medicinal preparations (dehydration, resorptive, vasoactive, nootropic, sedative, vitamin), the intake of six phytobes obtained by bioenergetic technologies was used. Complex therapy from phytospores was taken internally. Patients of the main group after the completion of the course of treatment noted a significant subjective improvement, correlating with the results of clinical objective examination and with instrumental data, autonomic samples (when they are repeated at the end of the course of treatment). The advantage of this method is the absence of side effects and complications, the possibility of using both inpatient and outpatient settings, both during the planned course of treatment, and to achieve a supportive effect during periods of remission.Key words: phytotherapy, phytospora complex, closed craniocerebral trauma, traumatic brain disease, autonomic disorders, rheumatoid arthritis.*Доктор медицины и философии, профессор Павлусенко И.

Modern Pre-operation Education of Surgeons: Principles Forming of Clinical Diagnosis

At the examination of a patient, a doctor evaluates clinical picture of the disease that manifests itself by a great number of various general and local symptoms caused by an etiological factor and pathogenesis changes of the different organs and systems of the organism. A purpose of the surgical patient examination is making of early, correct and precise individual diagnosis, and, based on it, effective and timely rendering of medical care via either pharmacologic nonsurgical methods or surgical intervention. Making a diagnosis is the most important task of the diagnostic and treatment process; solution of this task includes creative analysis of the disease clinical course, formulation of the provisional diagnosis and following determination of the additional examination methods scopes and diagnostic algorithm. From a formal aspect, diagnosis is based on the nosological principle and has to contain the name of a certain disease or injury according to the accepted nomenclature and classification of diseases; it is of importance to medical statistical goals and scientific research. Assessment of the findings of additional methods of examination in the aggregate with clinical signs allows carrying out of differentiation of similar diseases and gives an opportunity to make a clinical (final) diagnosis and define treatment approach. Concomitant diseases do not have etiopathogenetic relation to the underlying disease but able to influence substantially on the character of clinical picture, choice of the extent of other methods of examination and treatment

Venous thromboembolism in surgical practice.

A statistical retrospective analysis of the results of treatment of patients undergoing inpatient treatment in the surgical clinic, proctology and urology departments for 5 years was conducted, total number of patients – 27771, of them operated – 14849 (53.5%), postoperative mortality – 448 patients (3.0%), the overall mortality – 989 patients (3.6%). According to the analysis of the medical documentation, the total number of patients with pulmonary embolism (PE) was 98 (0.35%), the number of patients diagnosed during treatment – 56 (57.1%), at the time of pathoanatomical examination – 42 (42.9%); in 72 patients PE was directly responsible for death, 26 patients were cured by conservative methods. Of 98 patients with PE in 56 (56.1%), the main disease was oncological disease, in most cases in neglected form with distant metastases. A reduction in postoperative lethality by 40% was obtained, the reason for which, in our opinion, are: mandatory adherence to the recommended timing of the prevention of acute thromboembolic complications; prolongation of the prophylaxis term in patients who have undergone major surgical interventions or with postoperative complications that lead to a prolonged limitation of the patients' motor activity; a wider use of low molecular weight heparins

Developing a modern thermal strengthening technique for regulated fishplate cooling

A modern ecologically friendly technique for fishplate (joint bar) thermal strengthening by regulated water cooling is proposed. The proposed technique can successfully replace the conventional one - oil quenching - due to making the cooling process more controlled by obtaining a uniform temperature distribution over fishplate elements with a different mass such as heads and the wet. The oil quenching process is an out of control fire hazardous one and requires controlling the permanent cooling capability, fishplate flushing after the operation. It is necessary to utilize the oil and to have a special ventilation system. As a mineral oil substitute, the usage of polymer media has been investigated. Within the time, the polymer solution needs to be recycled; the high cost of polymer concentrates also plays an important role. Quenching by water spraying is the most ecological and controlled type of thermal strengthening. The technique was validated by a test bench experiment and implemented in the metallurgical industry. The mechanical properties have been obtained to meet the GOST 4133-73 technical requirements. Moreover, the analysis made showed that when the controlled cooling device is fitted into the line existing due to exclusion of the hardening tank and washing machine from the processing flow it is possible to save energy, exclude the expenditures for acquisition, the preparation of oil and washing mixtures as well as for regeneration of the oils used and washing solutions. © 2014 WIT Press.International Journal of Safety and Security Engineering;International Journal of Sustainable Development and Planning;WIT Transactions on Ecology and the Environmen
