Objectives

Genetic variations of LGALS3 (Galectin-3) were found to be associated with treatment resistance, mortality, recurrence, high tumor volume and multiple tumor involvement in solid organ cancers. The modulators of extracellular matrix (ECM), which is a dynamic factor in the larynx tissue with high biomechanical and regenerating ability, can play an important role. We aimed to investigate the relationship between the genetic variants of LGALS3, one of these modulators, with Laryngeal Squamous Cell Carcinoma (LSCC).

Methods

LGALS3 gene variations were genotyped by PCR-RFLP method using genomic DNA samples obtained from peripheral blood samples of 74 patients diagnosed with LSCC and 94 healthy controls.

Results

The C allele carriage for the Rs4652 genetic variant was found to be higher (p=0.017) in patients with LSCC. Statistical relationships were found between homozygous genotypes of this variant (CC/AA) with advanced tumor stage (p=0.017) and presence of reflux (p=0.036). CC genotype for rs4644 was found to be higher in cases with positive family history (p=0.036).

Conclusions

Our findings of LGALS3 gene variants, which are also found to be associated with other solid cancers, suggest that they may play a role in LSCC pathophysiology similarly.

Through centering the Florida Panhandle and using MTV’s Floribama Shore as an entry point, this essay articulates a Floridian-Southern identity. We organize this project around three themes that are heavily present in both Floribama Shore and our personal experiences as Floridian-Southerners: intra-regional tensions around religion, gender performances, and reproductive politics. Through layering our experiences among vignettes from Floribama Shore, we make visible the relationship between the consumption of popular media, the representations of Floridian-Southerners in popular media, the social and cultural regulation of hegemonic Southern deportment, and our own Floridian-Southern identity.

Published: June 2021

Non-destructive ultrasonic evaluation is one of the methods used for inspection in mechanical engineering. This method has diverse applications in various fields, including industry and medicine. The main purpose of this research is to identify a subcutaneous defect with ultrasonic waves. This is done by sending ultrasonic waves into the skin tissue and receiving backward echoes, simulating them using a software, and calculating the time difference using the speed of sound. In this research, the behavior of longitudinal and transverse waves is investigated in collisions with a defect by describing the genesis and application history as well as the principles and definitions of ultrasonic waves. In the test, first, the method of identifying the subcutaneous defect is explained. Then, the dimensions and stiffness of the defect are determined by analyzing the information obtained from the location. Using the 3.5-MHz probe, the defect was detected at a distance of 1.8 mm, indicating a high level of reliability compared to the sonography imaging device. This was while the 10-MHz probe failed to detect the defect just near the skin surface. The results confirm the choice of this method as a suitable method for detecting the subcutaneous defect.

The descending aortic aneurysm is one of the most catastrophic cardiovascular emergencies resulting in high mortality worldwide. Clinical observations have pointed out that stent implantation in the sick aorta should probably allow stabilization of the hemodynamic state of the patient's aorta. To better understand the hemodynamic impact of a stent-treated aneurysm, numerical simulations are used to evaluate hemodynamic parameters. These latter including flow profile, velocity distribution, aortic wall pressure and shear stress, which are difficult to measure in vivo. It should be noted that the numerical modeling assists in medical planning by providing patterns of blood circulation, in particular, the distribution of pressures and shear stresses in the wall. In this context, the pulsatile blood flow in the aneurysmal aorta with stent is studied by CFD (Computational Fluid Dynamics) simulations. Realistic boundary conditions time dependent are prescribed at the level of the different arteries of the complete aorta models. The hemodynamic profile of the aneurysmal aorta with stent was analyzed by contour planes of velocity vectors, pressures and shear stresses at different times during the cardiac cycle. The obtained results made it possible to show the effect of the stent on the improvement of the blood flow by solving the problems of hemodynamic disturbances in the aorta.  The methodology used in this work has revealed detailed and necessary information for the cases studied and shows the interest of the numerical tool for diagnosis and surgery.

Published: June 2021

Reinforced concrete (RC) corrosion is a leading of structural deterioration and premature degradation for the infrasturctures, with significant affected for safety, durability and reability. Therefore, early assessment of RC corrosion is important to prevent deterioration of the structure. The objective of this paper is to apply Boundary Element Method (BEM) for improving reinforced concrete (RC) corrosion assessment using field measurement data. In this study, the potential on whole domain of concrete structures was modeled by Laplace equation. The Laplace equation was solved by BEM, hence the potential on the concrete structure can be determined. The field data were measured by using half-cell potential technique and collected from an existing house in Aceh region that struck by the 2004 Sumatra tsunami. The simulation results show the use of BEM can improve the RC corrosion assessment. According to ASTM C876, the distribution of potential values on the concrete surface above the corroded area were in range -200 mV to -350 mV that indicated active corrosion was occurred. It can be inferred, the method can improve the field measurement data since it has capability to predict the corrosion profiles of reinforcing steel in more precise.

Published: June 2021

The paper examined a theoretical investigation of the stimulus of mass and heat transfer on the channel's peristaltic utilization of the MHD Bingham liquid. The research study is motivated to explore blood circulation in the little vessels by taking the slip, variable thermal conductivity, and thickness of the wall features into account.  The leading constitutive equations are established based on low Reynolds number and approximations for long wavelengths. The solution for the resulting nonlinear energy and momentum equations is obtained using a semi-analytic method, while the exact solution for the concentration field is obtained. Using the MATLAB software, the influences of different constraints on the interest of physiological quantities are represented graphically. One of the considerable outcomes of the current model exposes that the existence of variable fluid properties boosts the rate as well as temperature level areas. The rheological and flow properties of various biological fluids can be derived from this model as a particular case. Moreover, the formation of stuck bolus diminishes for larger values of the magnetic and velocity slip constraints.

The rapid development of modern technology requires new materials with predetermined properties. There is a need for materials with ultra-high strength, hardness, other characteristics and a common combination of these properties. The work was aimed at solving the problem of creating polymer composite materials that combine high physical and mechanical characteristics and thermal and electrical conductivity. Information was given on fillers, the use of which gives polymers thermal and electrical properties. Shown are the most commonly used in the composition of polymer composites fillers, advantages and disadvantages of each of the fillers. It was established that the use of carbon nanotubes allows obtaining polymer composites with the required performance characteristics. One of the problems when using nanoparticles as modifiers of reactive oligomers is their uniform distribution in the volume of the polymer matrix. Heterogeneity and uneven distribution of the dispersed phase can lead to dangerous defects in the material, so the technology of combining the nanofillers and the polymer matrix plays an important role. The possibility of obtaining polyvinyl butyral structured with carbon nanotubes in the process of its synthesis in the presence of carbon nanotubes was shown and the technological conditions of In situ synthesis are developed. Experimental samples of polyvinyl butyral structured with carbon nanotubes with high thermal and electrically conductive characteristics were obtained. Under optimal conditions of synthesis, in the obtained PVB samples structured with carbon nanotubes, the electrical conductivity of the composite increases by five orders of magnitude due to the high electrical conductivity of CNTs. For the obtained PVB, structured with carbon nanotubes, the fracture stress was significantly (by 62 %) increased, and the fracture deformation is reduced by approximately 38 %. The decrease in the deformation of the fracture during compression indicates an increase in the fragility of the polymer with the inclusion of CNTs. The prospects for the synthesis of polyvinyl butyral in the presence of carbon nanotubes to obtain a composite with a high level of achieved electrical and thermal conductivity were shown.

Subject and Purpose. Statistical data on how the satellite signal level varies with changes in the characteristics of tropospheric layers and lower-troposphere hydrometeors serve designers a useful guide in the development of systems for diagnosing weather conditions and hydrometeor characteristics. The aim of the work is to generalize results from the long-term research into daily dependences of X-band radio signal attenuation between the geostationary satellite and Earth terminals. On this basis it is possible to find relationship between signal level changes at the point of reception and geophysical atmospheric agents. Methods and methodology. A receiving measuring and recording complex developed by the authors is employed for the purpose of establishing relationship between geostationary satellite signal level at the receiving point and geophysical atmospheric agents. Results. A block-diagram of the receiving measuring and recording complex is presented, its operation described. Geometric parameters of the radio signal path of propagation have been considered. Signal level measuring results obtained using a Hot Bird geostationary satellite in the period from 03 to 17 January 2019 have been generalized and interpreted. Conclusions. X-band radio signal attenuation on the path from a geostationary satellite to the Earth has a daily dependence. The radio signal level variations are not connected with alterations in spatial and technical parameters of the geostationary satellite or receiving equipment. The day and night changes in radio signal level are attributed to different daytime durations and different angles of sunbeam (including twilight) incidence on tropospheric areas associated with the receiving antenna pattern in the propagation direction, which entails changeable temperature regime and moisture content in these areas. Geophysical agents in the highest tropospheric layers insolated from far beyond the horizon can also be interpreted for long-distance tropospheric radio wave propagation in these tropospheric regions.

Subject and Purpose. Tunable resonant structures make numerous microwave devices, among which are waveguide-dielectric and waveguide-coaxial resonators (WDR and WCR) built around cylindrical evanescent waveguides and involving a resonant short-circuit (RSC) plunger for tuning purposes. The present paper seeks to study specific features of the RSC-plunger operation in the evanescent waveguide and estimate the RSC-plunger efficiency. Method and Methodology. The RSC-plunger efficiency is approximately estimated in terms of the transmission line theory. Comparative experimental verification of the Q-factor increase is provided by an example of a 3 cm WDR resonator equipped with a RSC-plunger. Results. It has been shown that relevant formulae of the transmission line theory can be extended for the RSC-plunger efficiency estimation on the TEM and H11 oscillations. A possibility has been studied of the TEM type transformation to the H11 oscillation and back when the spurious resonance of the RSC-plunger falls within the WDR (WCR) tuning range. Conclusion. Insignificance of the effect that small deviations from the numerically predicted dimensions of the RSC-plunger exert on the RSC-plunger operation efficiency has been demonstrated. The RSC-plunger efficiency and a possibility to remove the spurious resonances from the resonator tuning range have been experimentally confirmed.

El lugar que ocupan algunas mujeres indígenas en Colombia en los contextos comunitarios y nacionales ha sido históricamente limitado en cuanto a sus acciones sociales y políticas en beneficio de sus poblaciones. Sin embargo, producto de sus luchas por el reconocimiento como sujetas de derecho, se han comenzado a vislumbrar formas participativas desde sus sentires y pensares, en el plano local y nacional. El presente estado del arte expone diacrónicamente las transiciones experimentadas en los ámbitos de participación de las mujeres indígenas de la Amazonía, el Cauca y la Sierra Nevada de Santa Marta, a fin de identificar el lugar que actualmente ocupan y sus formas de acción social y política. Los resultados reflejan que, si bien las mujeres son fundamentales en el cuidado y la preservación de sus tradiciones y saberes, también han emprendido formas de organización para involucrarse y tener representación en el ámbito sociopolítico local y nacional.

Published: June 2021

Barrier coverage in wireless camera sensor networks (WCSNs) has drawn the attention of research community since it promises an extremely large potential in applications involve movement detection and surveillance. As the battery resources are limited, improving the efficiency of energy is one of the key drivers for prolonging the lifetime of barrier coverage. However, most prior studies on this problem only worked on the networks with homogeneous sensors as well as omni-directional sensing coverage that have not been taken into account in WCSNs research. This paper thus investigates the problem of maximizing the network lifetime to ensure strong barrier coverage for heterogeneous case (MLBC-HWCSN). We formulate the problem, and then propose a Modify Maximum Flow Algorithm (MMFA) consisting of three stages: constructing the flow-network, finding the maximum flow and refining the solution to solve this problem. Experimental results on extensive instances show that the proposed methodology is suitable for the studied problem and more efficient than existing algorithms.

The calculating of ionic equilibria in the system «Pb(CH3COO)2 - CdCl2 - Na3C6H5O7 - ‎(NH3)2(CH2)2 - N2H4CS» allowed us to find conditions and concentration regions of PbS and CdS co-deposition. The determined conditions provided the CBD obtaining of CdxPb1−xS (0 ≤ x ≤ 0.033) substitutional solid solutions films with a cubic structure B1 (space group Fm ) with the grains preferred orientation (200). We established the evolution of the surface morphology of the synthesized films from cubic crystallites to hierarchical structure of globular aggregates by scanning electron microscopy. A quantitative analysis of diffraction patterns showed a decrease of microstrains in CdxPb1−xS films by a about factor of 3 with an increase of the cadmium chloride concentration in the reaction mixture from 0.005 to 0.14 mol/l. The excess of the cadmium content, established by EDX analysis, in the studied films as compared to its content in the solid solution is associated with the additional formation of the amorphous CdS phase up to 72 mol %.A Corrigendum is available for this article at https://doi.org/10.15826/chimtech.2021.8.2.12.

Published: June 2021

Aim. To compare markers of high cardiovascular risk and stress echocardiography results depending on the type of blood pressure (BP) response to exercise in patients without obstructive coronary artery disease.

Material and methods. Our single-center cross-sectional study included 96 patients without hemodynamically significant coronary artery stenosis according to coronary angiography or multislice computed tomography angiography. All patients underwent physical examination, cardiovascular risk stratification, electrocardiography, extracranial cerebrovascular ultrasound, echocardiography, treadmill exercise stress echocardiography.

Results. According to the test results, the patients were divided into groups with a hypertensive response (n=41) and a normal response to exercise (n=55). Patients with hypertensive response to exercise had significantly higher values of left ventricular mass index (100,0 (90,0; 107,0) g/m2 vs 76,0 (68,0; 91,0) g/m2, p<0,0000001) and left atrial volume index (36,7 (32,0; 46,0) ml/m2 vs 29,7 (26,3; 32,0) ml/m2, p=0,000003). There was also a higher level of cardiovascular SCORE risk (5,0 (2,0; 6,0) vs 2,0 (1,0; 3,0), p=0,004); patients more often had associated clinical conditions (36,6% vs 12,7%, χ2=7,57, p=0,006) and left ventricular diastolic dysfunction (39,02% vs 78,18%, χ2=15,21, p=0,0001). Pathological BP increase during stress echocardiography was associated with worse exercise tolerance (7,4 (5,6; 10,0) METs vs 10,2 (8,4; 11,95) METs, p=0,000041) and more frequent transient regional contractility impairment (46,34% vs 1,8%, p<0,00001), mainly of the lateral and inferior left ventricular walls.

Conclusion. Despite the absence of coronary artery stenosis, patients with hypertensive response to exercise are significantly more likely to have markers of high cardiovascular risk and require more careful monitoring of risk factors. Also, the hypertensive response to exercise is associated with more frequent regional contractility impairment even without coronary artery stenosis.

Published: June 2021

Aim. To study the relationship of psychosocial stress with the social environment, lifestyle and risk factors for cardiovascular diseases (CVDs) in middle-aged men.

Material and methods. A total of 301 men aged 41-44 years were examined. The study included a clinical examination and a survey using a standard questionnaire. The categorization of CVD risk factors (RF) was carried out in accordance with generally accepted criteria. The psychosocial stress was assessed using the Reeder scale. Depending on the psychosocial stress level, all surveyed men were divided into 3 groups by tertiles: group 1 (3,28-4,0 points) — mild stress, group 2 (2,71-3,14) — moderate stress, group 3 (1,28-2,57) — severe stress.

Results. More than half (53,5%) of males had manifestations of psychosocial stress, while 9% had a mild stress. With an increase in stress severity, the prevalence of hypertension increased and was significantly higher in men with a severe stress compared with their peers with mild stress (45,7% vs 31,7%; p=0,045). A significant linear trend was revealed between the levels of PSS and indicators of sedentary behavior. The strongest linear relationship was found between the psychosocial stress level and vital exhaustion (VE). The level of VE, stress at work, satisfaction with government performance and the level of family happiness are independent determinants of psychosocial stress level, and explain 33,1% of its variability. The proportion of the variance of psychosocial stress, uniquely explained by VE, is 20,8%, the absence of stress at work — 8,0%, satisfaction with government performance — 3,5% and the level of family happiness — 2,0%.

Conclusion. A high level of psychosocial stress in middle-aged men is associated with hypertension, sedentary lifestyle and lower values of most indicators of the social environment, lifestyle and quality of life. This must be taken into account along with other behavioral and psychosocial risk factors for noncommunicable diseases when developing population-based programs.

Aim. To study the relationship of different levels of high-sensitivity C-reactive protein (hs-CRP) with cardiovascular events and assess its contribution to the development of outcomes in Russian regions.

Material and methods. The work used the data from the multicenter study ESSE-RF — a representative sample of male and female population aged 25-64 years. All participants signed informed consent. The study included 10421 people (women, 6399 (61,4%)). The cohort was followed up from 2012 to 2019 (median follow-up period, 5,5 years). A hard endpoint (cardiovascular mortality and nonfatal myocardial infarction (MI)) was determined in 187 people, while a soft endpoint (nonfatal MI, stroke, revascularization, heart failure progression and cardiovascular mortality) — in 319 people.

Results. The results showed that hs-CRP is significantly associated with the main risk factors (with the exception of low-density lipoproteins). At the same time, it was found that optimal hs-CRP level for predicting the risk of cardiovascular events (CVE) in Russian population is significantly lower than 3 mg/L, but higher than 1 mg/L (1,54/1,89 mg/dL for men and women, respectively). Adding hs-CRP to sex and age significantly improved risk prediction (AUC, 79,7; 95% CI, 77,8-81,7). At the same time, adding a wide list of confounders to hs-CRP, sex and age does not improve the model’s predictive value (AUC, 79,7; 78,2-82,1).

Conclusion. This study for the first time showed a significant independent contribution of hs-CRP to CVEs development in the Russian population, and the addition of hs-CRP to sex and age significantly increased the predictive value of model.

Published: June 2021

The review describes the experience in intermittent hypoxic conditioning protocols in rehabilitation programs for patients with cardiovascular diseases. Based on randomized controlled trials, the efficacy and safety of intermittent hypoxic conditioning in patients with cardiovascular disease, including those with multicomorbidity in clinical practice, have been analyzed. From a physiological and clinical standpoints, the review justifies the need for further controlled clinical trials on hypoxic conditioning with a longer follow-up period both to expand the clinical indications for this method and to develop optimal combinations with exercise within cardiac rehabilitation programs. Discovery of the key mechanisms of adaptation to oxygen concentration changes and further research on hypoxia physiology will expand the application of this method in clinical and rehabilitation medicine in cardiac patients.

Published: June 2021

Despite the guidelines framed by the Indian government, there is non-compliance with site waste-management plans (SWMPs) as well as recycling at construction sites. This paper identifies the existing barriers and potential benefits and enforcement measures for implementing SWMP and recycling of construction and demolition (C&D) waste. Data gathered by means of a questionnaire survey, structured interviews and case studies are analysed using the beneficial index value (BIV) and relative mapping approach. From the results, it is concluded that factor B4 (‘no guidelines are available in the company’) has the highest BIV (6.70) and is the major barrier in implementing SWMPs. Factors BF4 (BIV: 7.42) with an efficient SWMP (‘there will be conservation of natural resources) and MI8 (BIV: 7.32) (‘legal requirements on environmental protection’) are the most significant benefit and enforcement measure for SWMP implementation, respectively. Probable behavioural, legal, technical and marketing barriers for enforcement of recycling are identified, and the suggested measures for efficient recycling are as follows: (a) behavioural – enforcement of construction in government projects using recycled materials; (b) technical – development of code provisions for acceptable quantity of recycled construction waste (CW) in various building components; (c) legal – higher landfill charge with strict penalties for illegal dumping; and (d) marketing – increasing sales outlets for recycling material. Also, successful European C&D waste-management practices are compared with Indian initiatives to improve the CW management status.

Background: Work-related musculoskeletal disorders (WRMSDs) are a public concern to social-care and health systems, as well as individuals. Globally, WRMSDs are classified as one of the prevalent causes of disability. Objectives: The primary objective of this study was to determine work-related risk associated with musculoskeletal disorders amongst flower farm workers. The secondary objective was to determine the relationship between WRMSD risk over the previous 12 months and socio-demographic characteristics. Method: A cross-sectional descriptive study was conducted. A sample of 270 participants was drawn from 897 farm workers, of which 184 presented with WRMSD as assessed using the Nordic Musculoskeletal Questionnaire. Quantitative data were collected using the Rapid Entire Body Assessment questionnaire. Inferential statistics were analyzed using the Pearson's chi-squared test (X2) test and based on an alpha level of p< 0.05. Descriptive statistics were presented using frequencies and percentages. Results: Respondents who reported medium risk were 49 (26.6%), 80 (43.5%) reported high risk while 55 (29.9%) reported very high risk. There was no relationship between WRMSD risk and socio-demographic characteristics. Conclusions: Flower farm workers in Kenya were found to be at risk of sustaining WRMSDs although socio-demographic factors did not play a role in the level of risk. Clinical Implications: The high prevalence of WRMSDs necessitates policy reform in the flower farm industry. Furthermore, the timely identification of potential disorders and the associated risk factors is necessary to ensure early intervention.

Background: Lateral Epicondylalgia (LE) is described as a tendinopathy at the common extensor origin at the lateral epicondyle of the humerus 1. Approximately 40% of people will experience LE at some point in their life. Recent studies highlighted the importance of assessing Middle Trapezius (MT), Lower Trapezius (LT) and Serratus Anterior (SA) muscle strength and also the importance of strength training in LE. CONTEXT AND PURPOSE: LE is the most common chronic musculoskeletal pain condition, causing significant pain, disability and lost productivity. Various studies focusing on scapular muscle strength and endurance give some indication that scapular muscle may need to be screened and treated. RESULT: There was significant effect on middle trapezius, lower trapezius and serratus anterior strengthening on reducing pain and improving functional status in patients with LE. CONCLUSION: The study primarily tried to analyze the effects of strengthening exercises to MT, LT, and SA along with conventional therapy on pain and functional status in LE patients. And this study reveals that addition of strengthening exercises to MT, LT and SA to the regimen enhances faster recovery in patients with LE. KEY WORDS: Lateral Epicondylalgia, Middle Trapezius, Lower Trapezius, Serratus Anterior.

COVID-19 affection is known to show multi-system involvement. As impairments are expected to be seen in various systems of the body, outcomes related to the function of different systems should be considered while evaluating a patient. This case series of 5 patients brings out the functional status of acute covid-19 patients admitted to the hospital. The evaluation involves outcomes related to Musculo-skeletal (30 second sit to stand test) pulmonary function (single breath hold & breath holding time) and functional capacity (6-minute walk test), which were practical in COVID-19 scenario, in view of maintaining restricted contact with the patient. The evaluation is also done at the time of discharge from the hospital to evaluate the need for post-acute-covid rehabilitation. KEY WORDS: COVID-19, impairments, Musculo-skeletal, pulmonary function.
Conclusion: A Critical Agenda for the Anthropocene
Authors: Pugh Jonathan , Chandler David
Published: June 2021

This conclusion restates the argument of the book that the engagement with islands in many debates today is not merely caught up in the slipstream of contemporary social and philosophical trends but is important to the ontological and onto-epistemological framing and tools of the Anthropocene. It clarifies that the book undertakes an analysis of the ‘work’ that thinking with islands, island imaginaries, island writers, artists, poets, activists, and island problematics is doing in these debates. Not only thinking about, but ‘with ‘islands has become an important resource for alternative and non-modern relational ontologies and understandings in the Anthropocene. The authors suggest that there is a need to not only critically focus upon how the modern episteme reductively grasps islands but to also establish a new critical research agenda focused upon how islands are being enrolled in debates about the Anthropocene as key sites for understanding relational entanglements and in the generation of many different forms of relational ontology and ways of knowing. Working with islands or relational thought per se is not one homogenous ‘other’ to modernist or mainland approaches, and so the chapter clarifies why it is important to start a new conversation about how we engage in working through the rich variety of possibilities and opportunities that these approaches afford. In conclusion the chapter elaborates upon how the authors see this book as an initial opening for a new critical agenda for island studies in the Anthropocene.
TÜRKİYE’DE KAMU YATIRIMLARININ İSTİHDAMDAKİ CİNSİYET EŞİTSİZLİKLERİ ÜZERİNE ETKİSİ: MEKÂNSAL PANEL VERİ ANALİZİ
Authors: ÇELİK Orkun
Published: June 2021

Bu çalışmanın temel amacı, mekânsal panel veri analizi yöntemini kullanarak, Türkiye’de bölgesel kamu yatırımlarının erkek ve kadın istihdamı üzerindeki etkisini incelemektir. Veri seti, 2004-2018 dönemini kapsamakta olup, Düzey-2 kapsamında 26 bölgeyi içermektedir. Elde edilen ampirik bulgulara göre, erkek istihdamında bölgeler arasında pozitif yönlü bir mekânsal etkileşim varken, kadın istihdamında istatistiki olarak anlamlı bir mekânsal etkileşim bulunmamaktadır. Ayrıca, bölgesel kamu yatırımlarının erkek istihdamı üzerindeki etkisi pozitifken, bu yatırımların kadın istihdamı üzerinde istatistiksel olarak anlamlı bir etkisi bulunmamaktadır. Bölgesel yatırım teşviklerinin ve bölgesel refahın, erkek ve kadın istihdamı üzerindeki etkisi pozitiftir. Bu pozitif etki, kadın çalışanlarında daha yüksektir. Bölgesel emek verimliliğinin erkek ve kadın istihdamı üzerindeki etkisi ise negatiftir. Bununla birlikte, bölgesel emek verimliliğindeki bir artış, kadın istihdamının daha fazla azalmasına neden olmaktadır.
Formation des enseignants de langue de scolarisation

Notre contribution va s’attacher à présenter un des dispositifs auquel nous formons les futurs enseignants de langue de scolarisation. Reposant sur la notion d’interdisciplinarité et mobilisant la notion de pédagogie de projet, ce dispositif est notamment destiné aux apprenants scolarisés au sein des unités pédagogiques pour élèves allophones arrivants (UPE2A). Nous verrons que l’interdisciplinarité peut ici se décliner d’une part du côté de l’enseignement / apprentissage des langues, d’autre part du côté de l’enseignement / apprentissage de la langue de scolarisation et des disciplines dites non linguistiques (Gajo, 2009). Des exemples concrets nous permettront de montrer comment l’interdisciplinarité permet l’émergence d’une conscience métalinguistique, facilite la maîtrise du genre scientifique scolaire et favorise l’inclusion des élèves. Nous serons ensuite amenés à réfléchir aux compétences que doit développer l’enseignant s’engageant dans ce type de démarche et à nous demander s’il y a, ou non, une redéfinition de son rôle.

Introduction. The final quality of products is formed during finishing operations, which include the grinding process. It is known that when grinding brittle materials, the cost of grinding work increases significantly. It is possible to reduce the scatter of product quality indicators when grinding brittle materials, as well as to increase the reliability and efficiency of the operation, by choosing the optimal parameters of the technological system based on dynamic models of the process. However, to describe the regularities of the removal of particles of a brittle non-metallic material and the wear of the surface of the grinding wheel in the contact zone, the known models do not allow taking into account the peculiarities of the process in which micro-cutting and brittle chipping of the material are combined. Purpose of the work: to create a new probabilistic model for removing the surface layer when grinding brittle non-metallic materials. The task is to study the laws governing the removal of particles of brittle non-metallic material in the contact zone. In this work, the removal of material in the contact zone as a result of microcutting and brittle chipping is considered as a random event. The research methods are mathematical and physical simulation using the basic provisions of the theory of probability, the laws of distribution of random variables, as well as the theory of cutting and the theory of a deformable solid. Results and discussion. The developed mathematical models make it possible to trace the effect on material removal of the overlap of single cuts on each other when grinding holes in ceramic materials. The proposed dependences show the regularity of stock removal within the arc of contact of the grinding wheel with the workpiece. The considered features of the change in the probability of material removal upon contact of the treated surface with an abrasive tool and the proposed analytical dependences are valid for a wide range of grinding modes, wheel characteristics and a number of other technological factors. The obtained expressions make it possible to find the amount of material removal also for schemes of end, flat and circular external grinding, for which it is necessary to know the amount of removal increment due to brittle fracture during the development of microcracks in the surface layer. One of the ways to determine the magnitude of this increment is to simulate the crack formation process using a computer. The presented results confirm the prospects of the developed approach to simulate the processes of mechanical processing of brittle non-metallic materials.
