Published: June 2019

Considerando as exigências por qualificação profissional, atribuindo ao próprio indivíduo a responsabilidade pelo gerenciamento da sua carreira, neste estudo buscou-se compreender de que forma as suas atitudes de maturidade de carreira se associam às concepções contemporâneas de carreira sem fronteiras e de carreira proteana. Para tanto, foi realizado um survey com estudantes universitários de duas universidades privadas, localizadas nas cidades de São Paulo, SP, e Salvador, BA. Os dados foram analisados estatisticamente por meio de testes multivariados, utilizando-se o software Statistical Package for Social Sciences (SPSS), versão 15.0, e da análise fatorial confirmatória (AFC) com modelagem de equações estruturais (MEE) por meio do uso do software Smart PLS 2.0 M3. Os resultados destacaram que quanto mais o indivíduo amadurece em relação à sua carreira, apresentando atitudes de planejamento e de exploração de carreira, mais atitudes relacionadas às concepções de carreira proteana e de carreira sem fronteiras poderão ser adotadas por ele. Além da contribuição teórica para maior elucidação dos conceitos contemporâneos de carreira proteana e de carreira sem fronteiras, este estudo favoreceu o desenvolvimento de programas de orientação de carreira.

A presente pesquisa objetivou identificar os estilos de liderança dos professores de uma instituição de ensino superior, localizada na cidade de Patos, na Paraíba. Para este estudo utilizou-se a abordagem quantitativa a partir do método dedutivo. A coleta dos dados ocorreu por meio do questionário Multifactor Leadership Questionnaire - 5x (MLQ), proposto por Bass (1985), e a análise a partir de estatísticas descritas básicas. Foram pesquisados 30 docentes de uma amostra total de 58, distribuídos em quatro cursos. Verificou-se que todos os estilos de liderança estudados são adotados pelos professores. No entanto, há um predomínio dos estilos transformacional (M= 4,15) e transacional (M=3,84), os quais apresentaram variação conforme a situação atribuída. Compreende-se, portanto, que existe demonstração de interesse dos professores em questões de liderança, no intuito de obter o melhor ambiente de trabalho e a máxima eficiência e eficácia dos seus alunos.
Distinguishing bone and soft tissue infections mimicking sarcomas requires multimodal multidisciplinary team assessment
Authors: Lex JR , Gregory J , Allen C , Reid JP , Stevenson JD
Published: June 2019

Introduction

The aims of this study were to report the presenting characteristics and identify how best to distinguish bone and soft-tissue infections that mimic sarcomas.

Materials and methods

A total of 238 (211 osteomyelitis and 27 soft-tissue infections) patients referred to a tertiary sarcoma multidisciplinary team with suspected sarcoma who were ultimately diagnosed with a bone or soft tissue infection were included. Data from a prospectively collated database was analysed retrospectively.

Results

Of all possible bone and soft-tissue sarcoma referrals, a diagnosis of infection was made in 2.1% and 0.7%, respectively. Median age was 18 years in the osteomyelitis group and 46 years in the soft-tissue infection group. In the osteomyelitis group, the most common presenting features were pain (85.8%) and swelling (32.7%). In the soft-tissue infection group, the most common clinical features were swelling (96.3%) and pain (70.4%). Those in the soft-tissue group were more likely to have raised inflammatory markers. Radiological investigations were unable to discern between tumour or infection in 59.7% of osteomyelitis and 81.5% of soft-tissue infection cases. No organism was identified in 64.9% of those who had a percutaneous biopsy culture.

Conclusions

This study has highlighted that infection is frequently clinically indistinguishable from sarcoma and remains a principle non-neoplastic differential diagnosis. When patients are investigated for suspected sarcoma, infections can be missed due to falsely negative radiological investigations and percutaneous biopsy. As no single clinical, biochemical or radiological feature or investigation can be relied upon for diagnosis, clinicians should have a low threshold for tissue biopsy and discussion in a sarcoma multidisciplinary team meeting.
Surgical treatment of type III temporomandibular joint ankylosis with a lateral arthroplasty while retaining the medially displaced condyle
Authors: Lin X , Li H-Y , Xie Q-T , Zhang T , Huang X-P , Zhou N
Published: June 2019

Introduction

We discuss our findings on the retention of the medially displaced residual condyle during the treatment of type III temporomandibular joint ankylosis, as well as the postoperative results observed during follow-up.

Materials and methods

Thirty-two patients with type III temporomandibular joint ankylosis that met the inclusion criteria of the study were included as subjects. The morphological integrity of the medially displaced residual condyle was verified in all of the participating patients through the use of cone beam computed tomography. The duration of the ankylosis ranged from 2 to 12 years. The maximum length that patients were able to open their mouths ranged from 6 mm to 14 mm. The surgical treatments used in this report included the separation of bony fusions between the condyle and the glenoid fossa, resection of the ankylosed sites, preservation of the displaced condyles in their medial position and suturing the remains of the disc to its typical position or taking the temporalis myofascial flap instead. The long-term results were evaluated by computed tomography and clinical follow-up examinations.

Results

Three-year postoperative follow-up examinations were performed for all of the patients included in this study. No recurrences were observed in the patients who adhered to the postoperative therapeutic advice. Patients had an average maximal mouth opening distance of 34.50 ± 5.75 mm as recorded during the final follow-up examination.

Conclusions

The released medially residual condyle can still function normally in temporomandibular joint movement and without reankylosis after a bone fusion resection. The displaced condyle should thus be preserved instead of being removed during the treatment of type III temporomandibular joint ankylosis.
Symptomatic trochanteric non-union following total hip replacement treated with reattachment combined with two-stage revision surgery of the femoral stem
Authors: Drampalos E , Bayam L , Oakley J , Hemmady M , Hodgkinson J
Published: June 2019

We present a case of symptomatic trochanteric non-union following total hip replacement treated initially with a Dall-Miles grip plate. After failure of this treatment, the patient had a two-stage revision.

Trochanteric non-union is one of the well-described complications after total hip replacement. It is frequently difficult to treat, while potentially causing weakness, altered gait and instability of the artificial joint.

We believe that reattachment of the trochanter combined with a staged revision of the femoral stem using a posterior approach for the second stage could be a valuable technique to be added to the orthopaedic armamentarium for recurrent and symptomatic trochanteric non-unions after primary total hip replacement, particularly after failure to treat with all the other techniques described in literature.
Arthroplasty infection rates in fractured neck of femur: single vs dual antibiotic cement
Authors: Savage P , McCormick M , Al-Dadah O
Published: June 2019

Introduction

Mortality rates following hip arthroplasty range between 10% and 40% after 12 months. A higher rate is attributed to postoperative complications, of which surgical site infection is one of the most significant. In an effort to reduce surgical site infection following arthroplasty, antibiotics can be added to the cement used. The primary aim of this study was to determine whether dual antibiotic impregnated cement can reduce the rate of deep surgical site infection in patients following cemented arthroplasty for fractured neck of femur compared with single antibiotic impregnated cement. The secondary aim was to compare the rate of superficial surgical site infection in single compared with dual antibiotic cement.

Materials and methods

A total of 206 patients were included. Group 1 included 108 retrospective patients who underwent arthroplasty for neck of femur fracture over a 12-month period using single antibiotic impregnated cement. Group 2 included 98 prospective patients who underwent arthroplasty for neck of femur fracture over a 12-month period using dual antibiotic impregnated cement. The rates of deep and superficial surgical site infection were investigated.

Results

Group 1 had a deep surgical site infection rate of 2.9% (n = 3), Group 2 had a deep surgical site infection rate of 0% (n = 0). Group 1 had a superficial surgical site infection rate of 3.7% (n = 4), Group 2 had a superficial surgical site infection rate of 5.1% (n = 5).

Conclusion

Dual antibiotic cement reduced the rate of deep surgical site infection compared with conventional single antibiotic cement in arthroplasty for fractured neck of femur. Only a marginal difference in superficial surgical site infection was observed.
Percutaneous hook wire assistance during laparoscopic excision of an intrarenal mass

Published: June 2019

Completely endophytic renal tumours pose challenges in laparoscopic nephron-sparing tumour excisions, with the use of intraoperative imaging techniques (e.g. ultrasound) being crucial when managing such tumours. The use of a percutaneous hookwire for tumour localisations are in use in several other surgical fields, such as breast surgery. An asymptomatic 52-year-old man presented with an incidental small right sided solid 33-mm interpolar renal mass identified on computed tomography. A guided insertion of a percutaneous localisation wire was carried out prior to a laparoscopic partial nephrectomy to assist in intraoperative tumour landmark/margins identification. Operative time was 210 minutes with zero ischaemia time, with an estimated blood loss of 200 ml. No perioperative complications were observed and the patient was discharged two days postoperatively. Histology revealed the mass to be a Fuhrman grade 2 clear-cell carcinoma with a 2-mm clear surgical margin. The patient remained free of recurrence at 16 months of follow-up. We have reported our first experience of wire localisation prior to laparoscopic partial nephrectomy for an intrarenal mass, which to our knowledge could be the first of its kind in renal surgery. Percutaneous wire localisation of endophytic renal tumours is potentially safe and effective and can allow nephron-sparing surgery where laparoscopic ultrasound is not available. Longer-term and further evidence should be encouraged.

Published: June 2019

Introduction

Surgical site infections are associated with increased morbidity and mortality in patients. The Getting It Right First Time surgical site infection programme set up a national survey to review surgical site infection rates in surgical units in England. The objectives were for frontline clinicians to assess the rates of infection following selected procedures, to examine the risk of significant complications and to review current practice in the prevention of surgical site infection.

Methods

A national survey was launched in April 2017 to assess surgical site infections within 13 specialties: breast surgery, cardiothoracic surgery, cranial neurosurgery, ear, nose and throat surgery, general surgery, obstetrics and gynaecology, ophthalmology, oral and maxillofacial surgery, orthopaedic surgery, paediatric surgery, spinal surgery, urology and vascular surgery. All participating trusts prospectively identified and collected supporting information on surgical site infections diagnosed within the six-month study period.

Results

Data were received from 95 NHS trusts. A total of 1807 surgical site infection cases were reported. There were variations in rates reported by trusts across specialties and procedures. Reoperations were reported in 36.2% of all identified cases, and surgical site infections are associated with a delayed discharge rate of 34.1% in our survey.

Conclusion

The Getting It Right First Time surgical site infection programme has introduced a different approach to infection surveillance in England. Results of the survey has demonstrated variation in surgical site infection rates among surgical units, raised the importance in addressing these issues for better patient outcomes and to reduce the financial burden on the NHS. Much work remains to be done to improve surgical site infection surveillance across surgical units and trusts in England.
Cadaveric allograft implantation to maintain limb viability in a case of traumatic pseudoaneurysm and poor native vessels
Authors: Wall JJS , Waduud MA , Scott DJA
Published: June 2019

Infected pseudoaneurysms are a vascular emergency, necessitating urgent surgical management. Owing to the infected field, a synthetic graft may be inappropriate in patients for whom autografting is impossible. Ligation of the artery is the usual management, often leading to amputation. We report a case of cadaveric allografting of the common femoral artery in a patient with a traumatic, infected pseudoaneurysm, who was taking immunosuppressive therapy for a liver transplant. The patient was followed up with ultrasound at 12 months and was found to have a significant graft stenosis, which was treated successfully with angioplasty. At 18 months, the patient remained well. This case describes the successful implantation of a cadaveric allograft into a patient with an infected pseudoaneurysm, negating the for need primary ligation.
Towards a Classification to Facilitate the Design of Domain-Specific Visual Languages
Authors: Bácsi Sándor , Mezei Gergely
Published: June 2019

Domain-specific visual languages (DSVLs) are specialized modeling languages that allow the effective management of the behavior and the structure of software programs and systems in a specific domain. Each DSVL has its specific structural and graphical characteristics depending on the problem domain. In the recent decade, a wide range of tools and methodologies have been introduced to support the design of DSVLs for various domains, therefore it can be a challenging task to choose the most appropriate technique for the design process. Our research aims to present a classification to guide the identification of the most relevant and appropriate methodologies in the given scenario. The classification is capable enough to provide a clear and precise understanding of the main aspects that can facilitate the design of DSVLs.

Published: June 2019

The networking dataplane is going through a paradigm shift as softwarization of switches sees an increased pull from the market. Yet, software tooling to support development with these new technologies is still in its infancy.In this work, we introduce a framework for verifying performance requirement conformance of data plane protocols defined in the P4 language . We present a framework that transforms a P4 program in a versatile symbolic formula which can be utilized to answer various performance queries. We represented the system using denotational semantics and it can be easily extended with low-level target-dependent information. We demonstrate the operation of this system on a toy specification.
Different Types of Search Algorithms for Rough Sets

Published: June 2019

Based on the available information in many cases it can happen that two objects cannot be distinguished. If a set of data is given and in this settwo objects have the same attribute values, then these two objects are called indiscernible. This indiscernibility has an effect on the membership relation,because in some cases it makes our judgment uncertain about a given object. The uncertainty appears because if something about an object is needed to bestated, then all the objects that are indiscernible from the given object must be taken into consideration. The indiscernibility relation is an equivalencerelation which represents background knowledge embedded in an information system. In a Pawlakian system this relation is used in set approximation.Correlation clustering is a clustering technique which generates a partition. In the authors’ previous research the possible usage of the correlation clusteringin rough set theory was investigated. In this paper the authors show how different types of search algorithms affect the set approximation.

Published: June 2019

The present study aimed to evaluate the effect of different concentrations of calcium on growth and development of silver vase bromeliad (Aechmea fasciata). Plants were fertilized three times a week with nutrient solutions formulated with HA solution (Hoagland and Arnon, 1950) modified with 0.25, 2.5, 5, 7.5, 10.0 or 12.5 mM Ca applied into the tank. After 90 days of experimentation, biometric and biomass measurements of root and shoot systems, and chemical analysis of leaves were assessed. The results showed that the concentration of 12.5 mM Ca in nutrient solution is recommended for silver vase bromeliad fertilization.

Desdobramentos do episódio do encontro entre Odisseu e Nausícaa, narrados a partir do Canto VI da Odisseia, quando o herói finalmente alcança a ilha dos Feácios, são no ensaio discutidos sobretudo com base na ocorrência do choro. O pranto desarma o ímpeto belicoso e facilita a integração daqueles que a ele se entregam aos grupos de que fazem parte, ou que os asilam. Num segundo momento, a recriação do mesmo episódio, no Ulysses, de James Joyce, é enfocado, sendo então realçados os inevitáveis contrastes daí advindos, resumidos na troca do lamento solidário acentuado por Homero pela busca egoística, ou romântica, de prazer e sucesso.

Nowadays, the wavelet transform is frequently used in processing and interpretaion of potential field data, to detect accurately the location of the anomaly sources and their properties. For gravity anomalies of adjacent sources, they always superimpose upon each other not only in the spatial domain but also in the frequency domain, making the identification of these sources significantly problematic. In this paper, a new mother wavelet for effective analysis of the locations of the close potential field sources was introduced. By theoretical modeling, using the wavelet transform modulus maxima (WTMM) method, we set up a correlative function between the scale parameter and gravity source depth. Moreover, a scale normalization on the wavelet coefficients was applied to enhance resolution for the separation of these sources in the scalograms, thereby determining their depth. After verifying the reliability of the proposed method on the modeling data, we proposed a process for the location of the gravity anomalies of adjacent sources using the wavelet transform, and then application for analysing some of the gravity profiles in the Mekong Delta. The results of this interpretation were consistent with previously published results, but the level of resolution for this technique was quite coincidental with other methods using different geological data.

Published: June 2019

Tetrodotoxins in salted and fermented ovaries with rice bran of a puffer fish Lagocephalus inermis (Temminck & Schlegel, 1850) during five months were determined by high-performance liquid chromatography with fluorometric detector (HPLC- FLD). The analysed results showed that the original ovaries contained only tetrodotoxin with content of 7.59 µg/g fresh weight. 4,9-Anhydrotetrodotoxin - an isomer which is less toxic than tetrodotoxin has been found in all ovary samples since the second month. Tetrodotoxin in the ovaries disappeared in the 4th month of the experiment. In addition, 4,9-anhydrotetrodotoxin level in ovaries increased during fermentation. The present study contributes to clarifying the chemical mechanism of decreasing tetrodotoxin content in fermented ovary of puffer fish.

For the first time, the total lipid content and lipid class composition of  the Vietnamese soft corals (Sinularia brassica, Sinularia flexibilis) and fire corals (Millepora dichotoma, Millepora platyphylla) were investigated. The results indicated that the total lipid content of the investigated species was significantly different. Compositions of the lipid classes were analyzed using TLC and image analysis program Sorbfil TLC Videodensitometer DV and the results showed that phospholipids (PL, 10.91–16.02%), monoalkyldiacylglycerols (MADAG, 20.69-39.92%) and hydrocarbon wax (HW, 29.83-37.17%) were the main lipid classes of the total lipid in soft coral species. Meanwhile, PL (24.11-33.23%), TG (14.27–34.92%), ST (10.10–14.50%) and HW (12.08–19.95%) were predominant in fire coral species. ST, TG and FFA contents in soft and fire corals were at low level. DG was only present in the Sinularia flexibilis but not in other studied corals.
Distribution characteristics of reservoir fluid properties in Cuu Long basin
Authors: Hung Nguyen Manh , Tien Hoang Dinh , Ky Nguyen Viet
Published: June 2019

Oil and gas have been discovered and produced from Cuu Long basin for more than 20 years however the distribution charateristics according to stratigraphy have not been studied. In this study, data from more than 200 PVT reports of more than 30 discoveries and published reports of previous studies were investigated to find out the distribution characteristics of reservoir fluid properties. The results show that oil and gas in Cuu Long basin mainly follow normal distribution, in some areas they are in redistribution (retrogradation) stage. Saturation pressure, GOR and compressibility are very high at the centre area and rapidly reduce at the margin area, whereas reservoir fluid density is in the inverse trend. Oil and gas have tendency to accumulate in NW-SE direction. Condensate discoveries in Cuu Long basin mainly result from redistribution process except some discoveries in center of basin.
Evaluation of crack width in roller-compacted concrete pavement
Authors: Sok Tetsya , Kim Young Kyu , Oh Heung-Un , Lee Seung Woo
Published: June 2019

Crack width is a critical factor influencing the behaviour and performance of a roller-compacted concrete pavement (RCCP) because wide cracks can result in water infiltration and poor load transfer, leading to faulting, excessive deflection and further cracking. The crack width may be affected by temperature changes, concrete drying shrinkage and creep, crack spacing and the base material. An empirical equation to predict the crack width has been proposed by the American Association of State Highway and Transportation Officials (Aashto). However, this equation is quite simplified because a uniform strain distribution is assumed along the slab length. In this work, a mechanistic approach to predict the crack width in RCCP was developed using a three-dimensional finite-element model considering a non-linear friction model between the slab and the base. Moreover, the effect of concrete creep on the crack width was incorporated using the effective modulus method. The mechanistic model was validated with crack width data from two full-scale RCCP test sections in South Korea. The mechanistic model showed good agreement with the field data, whereas the Aashto equation tended to over-predict the crack widths. The proposed model is thus helpful to predict the crack width in a concrete pavement slab for given environmental conditions, slab geometry, material properties and base material.
El tráfico de cocaína entre América Latina y África Occidental
Authors: Sampo Carolina
Published: June 2019

Desde hace más de 10 años, un tercio de la cocaína que ingresa a Europa lo hace a través de África Occidental. Sin embargo, poco se sabe de la relación existente entre América Latina, como región productora de cocaína, y África Occidental, como zona de tráfico, acopio y consumo. Este trabajo, de carácter exploratorio, busca entender por qué África Occidental se presenta atractiva para los traficantes latinoamericanos y cómo funciona el vínculo entre ellos y los africanos. La hipótesis que plantea es que los Estados africanos han sido cooptados por las organizaciones criminales. Estas generan mayores incentivos para las organizaciones criminales latinoamericanas, que consideran que dicha ruta es menos riesgosa y más redituable que otras, aun cuando tengan que negociar, parte de la logística con sus pares africanos. Como resultado, se han detectado tres hubs por los que ingresa la cocaína proveniente de América Latina: uno en la Costa Atlántica, uno en el Sahel y otro en el golfo de Benín. 
Abstract
For more than 10 years, one third of the cocaine that enters Europe does so through West Africa. Nevertheless, little is known about the relationship between Latin America, as the region that produces cocaine, and West Africa, as a zone of trafficking, stockpiling and consumption. This article, which is of an exploratory kind, seeks to understand why West Africa presents itself as attractive to Latin-American traffickers and how the link between them and the Africans works. The hypothesis stated in this work is that African States have been co-opted by criminal organizations. They generate  greater incentives for Latin American criminal organizations, which consider this route less risky and more profitable than others, even though they have to negotiate part of the logistics with their African peers. As a result, three hubs through which cocaine comes from Latin America have been detected: one on the Atlantic Coast, one in the Sahel and another one in the Gulf of Benin.
Enhancing the efficiency of formal low-cost houses by the development of a new low-cost ceiling system
Authors: Mathews E H , Weggelaar S
Published: June 2019

Existing formal low-cost houses in South Africa have been shown to be very thermally and energy inefficient. This could be problematic for the country since the government has promised to build roughly 3 million more of these houses in the near future. Inefficiency in these houses can be effectively addressed by installing ceilings, but the cost thereof is unfortunately too high to be affordable to the applicable sector of the population. New options need to be considered to reduce costs. Research has shown that practically any material can be used as a ceiling if it provides a barrier to heat flow and eliminates infiltration. The material should ideally possess good thermal properties and comply with standard building regulations, but most importantly, it must be very cheap and easy to install. The low-cost ceiling proposed in this paper has all of these attributes, and installation thereof could result in substantial energy savings, improved indoor comfort, and a better quality of life
A new approach to the efficiency concept in South African industry
Authors: Pitis C.D. , Van Rensburg J.F. , Kleingeld M. , Mathews E.H.
Published: June 2019

This millennium is marked by a new trend: efficien-cy. In the actual economical environment, business sustainability requires high-efficiency technological processes. The efficiency concept has to be present at all levels of industrial activities. However, as com-mon practice, the efficiency concept is still regarded equivalent to ‘energy efficiency’ as mentioned in the Intergovernmental Panel on Climate Change (IPCC 1996), and specifically re-defined by the Federal Energy Management Plan (Department of Energy Federal Register 1994.By analysing specific industrial processes, the authors have defined a global concept of efficiency presenting results of sound research in this field, with reference to electric motors and drives. Typical examples supporting the theoretical background reveal general impacts on the South African econo-my by implementing this new concept:•    Technical and economical performance improvement and competitiveness of South African companies to international standards;•    Defusing an incipient energy crisis in the sector;•    Improving environmental conditions (less ema-nations of carbon dioxide at the power plants); and•    Creating new job opportunities in the sector. The global concept of efficiency proposed in this paper can be further developed in assessing effi-ciency of various processes, thus improving compa-nies’ corporate energy policy.

This paper summarizes a comparison of an always-on and a programmable type industrial style infrared dryer. The load power supplied for each kind of dryer is analysed. The design and imple-mentation of an infrared radiation controller is also presented. The study includes both the theoretical aspects of the design process as well as an overview of the practical facets involved. The infrared drying system controller was subjected to comparative test-ing with an on/off control model, in order to observe the controller’s performance and validate its effec-tiveness. The proposed controller contributes to a more energy efficient drying system than the always-on techniques that are employed to fluctuate the heater temperature.
An energy system planning model for the industrial sector in Nigeria
Authors: Njoku P.C.
Published: June 2019

This paper reports the energy system modelling projection in the industrial sector of Nigeria. It is car-ried out to provide a long term perspective on the Scenario buildings for the industrial energy system of Nigeria. The projections have inter-sectoral con-sistency only to the extent those of the Federal Republic of Nigeria have to the inter-industrial link-ages, which are no doubt important. However, it appears that input-output tables have not been instructed and regularly impeded and expanded as part of the planning scenarios that have been gen-erated on the contested demand, which is to assume constant energy intensity in future years. The basis for projecting energy demand in the industrial sector is to estimate the likely changes in energy consumption intensity and the ratio of ener-gy consumption to value added. It is considered expedient and pragmatic to use a scenario for con-structing an optimal level forecast, projecting a desirable energy equilibrium pattern for the year 2010.
Design analysis methods for Stirling engines

Published: June 2019

Worldwide attempts are being made to increase the use of our renewable energy sources as well as to use our current fossil fuel energy sources more effi-ciently. Waste heat recovery forms a substantial part of the latter and is the focus of this project. Stirling technology finds application in both the renewable energy sector and in waste heat recovery. Investigating the applicability of Stirling engines in the above-mentioned fields is relevant to develop more efficient external combustion units as well as to utilize our renewable energy sources. Developing a design analysis and synthesis tool capable of opti-mizing Stirling powered units forms the main objec-tive of this project. The methodology followed to achieve this, involved the application of three differ-ent methods of analysis, namely the method of Schmidt, the adiabatic analysis and the simple analysis based on a five volume approach. The Schmidt analysis is used to obtain the internal engine pressure which is a required input for the adiabatic analysis while the simple analysis intro-duces pumping losses and regenerator inefficien-cies. These methodologies are discussed briefly in this paper. Experimental verification of the analyti-cal data was carried out on a Heinrici Stirling engine and both the analytical data and the experi-mental data are presented here. Shortcomings of these methods of analysis are highlighted and an alternative approach to solve particular shortcom-ings is presented.

Published: June 2019

A new method of cloud point extraction coupled with ultrasound-assisted back extraction that is followed by GC-FID determination of permethrin and α-cypermethrin in waters, vegetables, and fruits was developed. The effect of several parameters on the extraction process, such as the concentration of Triton X-114, pH, incubation time, equilibration temperature and centrifuging parameters were studied and optimized. The complete extraction of pesticides with using 0.5 % solution of Triton X-114 at phase separation temperature of 40 °C is observed in the pH range from 2.0 to 9.0 when both analytes are present in the solution in electroneutral form. The surfactant-rich phases were formed by centrifuging solutions at 4000 rpm for 10 min. The method was validated and characterized by the following metrological parameters: for permethrin LOD (3σ) - 0.12 μg/ml, LOQ (10σ) - 0.38 μg/ml, working range 0.38 - 2.0 μg/ml; for α-cypermethrin LOD (3σ) - 0.04 μg/ml, LOQ (10σ) - 0.13 μg/ml, working range - 0.13 - 2.0 μg/ml. The procedure was used to determine permethrin and α-cypermethrin in potatoes, cabbage, pepper, table beets and apples after their treatment with commercial preparations of pesticides. The obtained results show that the sensitivity, metrological characteristics, ecological safety, simplicity and convenience of the suggested procedure exceed published methods that are based on pesticides extraction using organic solvents.
“Digital Magic” of Power: the First Managerial Revolution
Authors: Isayev I. A.
Published: June 2019

The article deals with the problem of ideological scientific sources of the first technologies of power. The myth of the «machine of power» was born simultaneously with the myth of digital management of the society. The first rational foundations of the concept of technological process were developed by thinkers of the Renaissance and the Modern Тimes. The first technological revolutions changed approaches to the problems of politics and law. Deep spiritual and intellectual processes were conceptualised in legislation and political technologies. The magic of managing things and people formed the basis of the Mega-machine that had been evolving since ancient times till the Modern Times. Even contemporary technologies of control and governing contain the elements of magicism reduced to technical manipulation of individuals and entire masses. A number, figure and manipulation form the heart of political technologies.
Court Practice in Family Disputes: Problems of Discretion on the Verge of Law-Making
Authors: Tarusina N. N.
Published: June 2019

The article is devoted to the analysis of the problems connected with the law-making function of court practice in family disputes. The history of this function, which is not one of the classic types of judicial activity, has several factors: paticularities of family legal relations, situational nature of the majority of family law norms as a key prerequisite for broad judicial discretion in its various forms — concretization, interpretation, subsidiary application of the legislation, application of analogy, conflict resolution that in some cases can be qualified as legal stances of normative type. As an illustration, the provisions of a number of current rulings of the Supreme Court of the Russian Federation on family matters are offered.

It is noted that the purpose of the rule-making approaches applied in the court practice involve primarily considerations of fairness in relation to expediency. At the same time, firstly, the criteria for choosing situations for the formation of a trend towards a fair resolution of family disputes of a certain category are not quite clear; secondly, the legal approaches under consideration do not exclude a direct conflict with the family law; thirdly, they remain in the status of recommendations for decades instead of being modified within a reasonable time and transformed into an improved family legislation.

The author associates himself with the scholars who consider it necessary, if judicial law-making is inevitable, to regulate its grounds, criteria and procedure directly via civil procedural and/or other laws.
Some Issues of the Legal Regulation of the Cossacks in Constituent Entities of the Russian Federation
Authors: Zenin S. S.
Published: June 2019

The article analyzes the current state of the legal regulation of social relations existing among the Russian Cossacks at the level of constitutent entities of the Russian Federation. The author examines the legal form of regulating social relations and the content of normative legal acts adopted in the constituent entities of the Russian Federation regarding the Russian Cossacks. The paper concludes that there is a need to develop a more effective mechanism of participation of constituent entities of the Federation in the legislative process on issues of joint jurisdiction at the federal level. The author highlights the need to apply a model legislation in order to unify the provisions of regional normative legal acts. The paper focuses on the importance of a clearer definition of the legal status of the Cossacks who have assumed obligations to carry out public service, including taking into account the possibility of using physical force, special means, and cold weapons that they have the right to wear as elements of national clothing.
Legal Interpretation of Bribery (Statistical Analysis)
Authors: Nemchenko G. I.
Published: June 2019

Anti-corruption is one of the priorities of state policy and the most important activity of law enforcement agencies, which are given a central place in the implementation of anti-corruption legislation and its enforcement. In order to combat corruption and in accordance with paragraph 1 part 1 of the Federal law of 25.12.2008

№ 273-FZ «On combating corruption» the decree of the President of the Russian Federation of 29.062018 № 378 approved the national anti-corruption plan for 2018-2020.

Bribery, which is the core of economic and legal violations, occupies a special place in the structure of corruption crime. The number of crimes on the registered facts of bribery is constantly growing and deviation from the norms is transformed into an acceptable norm that contradicts the interests of the civil service and state power.

Considering bribery as a type of economic criminal offense, the author proposes an analytical decomposition of crimes committed in the period 2001-2015, the natural trends and random deviations from the trend. New coverage of crimes consists in building statistical relationships, dependencies and interdependencies between contractors, which are governed by the ideology of Law and Economics. An interdisciplinary approach aimed at improving anti-corruption measures expands the scientific and methodological potential of bribery research.

As a measure of dependence, correlation and regression coefficients are used in the microsystem of the transaction organized without intermediaries. The axiom of a «bribe» is offered, increasing the cost of the service of the bribetaker and distributed subsequently by the bribe-giver on consumers of the benefits created by it.

The tested procedures can be used to create mechanisms for promoting anti-corruption values and scientific support of anti-corruption.
