Analyzing multi-word expressions aids in understanding how native and non-native English speakers in secondary schools differ in expressing their attitude and stance, especially in written compositions. Thus, this study sought to compare and analyze the attitudinal/stance lexical bundles used by students in their narratives, specifically in terms of epistemicity, desire, obligation/directive, intention/prediction, and ability to conclude which between the native and non-native speakers used attitudinal/stance lexical bundles more frequently. Results showed that non-native English learners demonstrated a greater number of attitudinal/stance lexical bundles compared to their native counterparts, except in terms of desire. Non-native speakers employed more indirect and impersonal variations, unlike the native speakers whose expressions were more direct and straightforward. In line with these findings, further studies on the implications of the observed rarity and higher frequency of attitudinal/stance bundles use by non-native learners are hereby recommended.

They assume a fundamental job in the effective utilization of inclusive education as they are seen as critical during the time spent incorporating students with special needs into regular classes. Consequently, this study is intended to determine the preparedness of state-funded teachers in handling inclusive education. Specifically, this study was to determine the level of awareness and attitudes of public-school teachers towards the implementation of inclusive education. In particular, it sought to identify the demographic profile of the public-school teachers, their level of readiness in handling inclusive education in terms of awareness, attitude, and skills and the significant difference in the level of readiness of teachers towards inclusive education when grouped according to profile. The output of this study is the training program to enhance the awareness, attitudes, and skills of teachers towards inclusion. The study used a descriptive – quantitative method of research using both the quantitative and qualitative techniques of data collections. Frequency distribution, percentage, standard deviation, MANOVA, and descriptive statistics were used as statistical tools of this study. The critical discoveries of the investigation unveiled that state-funded teachers’ status in dealing with inclusive education is progressively mindful on the significance of inclusive education. In any case, they need training, classes, and workshops because few mainstream teachers are new to mainstreaming. They are agreeable on inclusive education. However, they need refreshed hands-on training. Moreover, they are skilled in their own personal capacity, but they lack further trainings specifically on the crafting of Individualized Education Plans. Therefore, there is a need to have a separate subject on disability and inclusive education in the teacher training courses.

In the face of the constant tightening of environmental regulations, alternative sources of fuels and energy are being increasingly sought. The European Union strives to introduce waste-free or low-waste closed-loop technologies using material and energy recovery to manage natural resources in a rational manner. Therefore, European regulations require member states to progressively restrict the amount of landfill waste. In Poland, these requirements have been included in the Act on waste and the Act on order and cleanliness in the commune. In addition, since 1 January 2016, it has been forbidden to store waste with a calorific value exceeding 6 MJ/kg, which is why in recent years there has been an increase in interest in the thermal transformation of municipal waste. Therefore, the article presents the current shape of waste management in Poland, and also introduces the dominant form of RDF management in the cement industry. Nevertheless, the capacity of cement plants is limited, and the energy use of fuels from waste encounters difficulties related to a significant reduction in pollutant emissions, which is why the use of modern installations for the thermal conversion of waste such as pyrolysis and gasification is increasingly considered. Taking into account the promising energy properties of secondary fuels obtained during the pyrolysis process, the chemical composition of gas from RDF pyrolysis was modeled for a pilot installation operating in Poland using CHEMKIN-PRO software. Determination of the combustible components allowed the calorific value of pyrolytic gas to be estimated, ranging from 28.2 - 28.7 MJ/m3. The obtained calorific value is much higher than the average calorific value of RDF (11-18MJ/kg) [1], which encourages wider use of the waste pyrolysis process in order to obtain secondary fuels with promising energy parameters. It will contribute to a further reduction in the amount of deposited waste, and thus to creating environmentally-friendly closed-loop waste management.

Family physicians are supposed to be the first to face with patients at the acute or chronic terms of the illnesses as a primary care facility. In burn injuries, however, patients mostly seek medical attention at the health facilities other than the family physicians. We aimed to analyze the current situation in our country and its social and economic outcomes. Between July 1st and august 31st 2012, among 153 patients admitted to our burns outpatient clinic, 119 were included to the study. Twenty-one patients' family physicians and 21 family physicians not related to our study group were randomly sampled. Patient demographics, clinical course, and treatment cost were recorded. Patients' selection criterion in between primary care and us (tertiary referral hospital) is evaluated by a questionnaire. A survey carried out among family physicians to evaluate their backgrounds on burn management and attendance to postgraduate courses. The male to female ratio of the patients was 1.25 (66/55) and mean age was 29±18.1. Of the patients, 95% reached the hospital with a vehicle and 70.6% had an accompanier. Only 13.4% of the patients sought medical attention at the primary care. 52.4% (22/42) of the family physicians did never attend to a postgraduate course. During the prospective follow-up, there necessitated 501 visits and dressing changes. Total treatment cost for an average course was 109.4 $ or 26 $ for a visit. If the treatments were done at the primary care, a 42.2% reduction at costs could have been achieved. Even mostly conditions appropriate for management at the primary care, burn patients mostly bypass this stage. In addition, family physicians are not well updated on the current burn wound care. Bypassing the primary care add an extra physical, psychological, social, and economic burden to patient and also leads extra workload to the related health facilities. Bypassing causes additional economical cost to patients and insurance agencies. Policies should be settled for the management of outpatient burn patients at the primary care.

RSA’s strong cryptosystem works on the principle that there are no trivial solutions to integer factorization. Furthermore, factorization of very large semi primes cannot be done in polynomial time when it comes to the processing power of classical computers. In this paper, we present the analysis of Fermat’s Last Theorem and Arnold’s Theorem. Also highlighted include new techniques such as Arnold’s Digitized Summation Technique (A.D.S.T.) and a top-to-bottom, bottom-to-top approach search for the prime factors. These drastically reduce the time taken to factorize large semi primes as for the case in RSA Cryptosystem.

The rising defaults on subprime mortgages in the US triggered a global crisis for the money markets. The fact is the global financial crisis started with the US policies. What began with elevated losses on US subprime mortgages has spread beyond the borders of the United States and the confines of the mortgage market. Many of the world’s leading investment banks have collapsed as a result. Depression, a thing of the past, has made a striking comeback. Will it come back again in the future? Who is to blame? What should be done to avoid future incidence?
Viscoelastic systems for well construction

One of the most important factors ensuring the required quality of well cementing is the use of effective flushing fluids (spacers). Among these fluids are viscoelastic systems (VES), which provide the best displacement of the drilling fluid during the cementing process.
The article discusses the mechanism of polymerization of viscoelastic systems when using polyacrylamide cross-linked with polyvalent metal cations and the prospects for using these systems for oil and gas wells cementing. Models of the viscoelastic systems flow and their differences due to the presence of normal stresses in viscoelastic systems are shown in this article. The substantiation of the component composition of viscoelastic systems and their main properties, ensuring their efficiency as flushing fluids are given. The article also provides a description of the scientific instruments that were used during the research.
It has been experimentally confirmed that it is necessary to use additives with the highest oxidation state when choosing a polyvalent cation as a "cross-linker" for viscoelastic systems. This will help to increase the rate of strength characteristics development. The most adequate ratios of components have been experimentally substantiated and the best solids-carrying capacity of a viscoelastic flushing fluid in comparison with other types has been proven. This eliminates the possibility of cement slurry flowing down in the annular space after the completion of the cementing process.
The special installations proved the best degree of wellbore cleaning in vugular formation zones with a laminar flow regime. In order to minimize the negative effect of polymer films from viscoelastic systems on the adhesion of the cement stone to the casing strings it is recommended to inject a portion of the liquid containing the polymer destructor after a portion of the viscoelastic fluid.
Increased oil recovery through the use of combined technology

There is a growing number of fields in the world that are at the last stage of development. These fields are characterized by high residual oil saturation and water saturation. In addition, newly discovered fields are characterized by the content of high-viscosity oil. The development of such reservoirs is associated with great difficulties. This paper considers a combined technology that allows to intensify oil production from oil reservoirs. The studies were carried out on a homogeneous reservoir model in the following sequence. First, we carry out the displacement of oil by injecting electrochemically modified water (catholyte). Then we pump in a gas-liquid emulsion slug, which we push through with water or catholyte. The combined action of the emulsion and catholyte leads to an increase in the pressure drop and a change in the filtration rate. As a result, this leads to an increase in the oil recovery factor.

INSERÇÃO PROFISSIONAL DOS EGRESSOS DE CURSOS TÉCNICOS DO INSTITUTO FEDERAL GOIANO - CAMPUS MORRINHOS, 2010-2014
Authors: de Oliveira Érika Lemes
Published: May 2022

A educação profissional e tecnológica constitui-se em uma política pública voltada para a integração entre o ensino e as demandas de desenvolvimento econômico e social, em âmbito local e regional. Inserção profissional dos egressos de cursos técnicos do Instituto Federal Goiano - Campus Morrinhos, 2010-2014 discute o processo de inserção profissional de egressos, e a percepção dos empregadores em relação aos profissionais técnicos contratados. Metodologicamente é caracterizada como pesquisa analítica, com abordagem quantitativa por meio da análise estatística dos dados coletados, tendo como procedimento técnico a pesquisa de campo. As informações foram obtidas por meio da aplicação de questionários a dois grupos de informantes, sendo eles: egressos de cursos técnicos, com adesão de 98 destes, representando 44% do total de egressos, e 11 empregadores com atuação na região de Morrinhos - GO. Verificou-se que 65% dos egressos estão trabalhando, destes 30% atuam em sua área de formação técnica, 86% deram continuidade aos estudos e 53% declararam estar frequentando ou terem concluído curso superior em área correlata à da formação técnica. Os empregadores foram unânimes ao afirmar que a formação técnica representa diferencial no currículo do trabalhador no momento da seleção de emprego e a maioria deles está satisfeita com o desempenho profissional apresentado pelos técnicos contratados. O desenvolvimento da pesquisa indicou a necessidade de aprofundamento nas discussões institucionais sobre a matriz curricular dos cursos técnicos; as áreas dos cursos ofertados e maior integração entre as instituições de ensino e o setor produtivo, buscando a eficiência e a retroalimentação das políticas educacionais voltadas para a educação profissional e tecnológica.
