Performance Assessment of Steel Moment Connections Retrofitted with Various Reduced Section Patterns
Authors: Sivandi-Pour Abbas
Published: December 2019

It is of high importance in seismic retrofitting of lateral load-bearing systems to increase the connections performance. The crucial point in the steel frame retrofitting process is to create plastic hinges in these types of frames. The formation of plastic hinges in beams and near columns generates large strains on column flanges as well as welding metal and heated surroundings, which can lead to brittle failure. The connection should be designed in such a way as to allow plastic hinge formation at certain points of the beam. One such method suggested for retrofit connections is to reduce the beam section locally away from the connection zone. There are various patterns available to locally reduce the beam section, such as circular, elliptical, and symmetric/asymmetric. In recent years, different proposals have been presented to design these connections which vary from older instructions. For this study, radiused cuts in the flange and slotted holes in the web of connection beams were selected for retrofitting analysis. Cyclic behavior, energy damping levels, and ductility of these connections were studied and compared before and after the retrofit by using nonlinear dynamic analysis. The results showed that the symmetrical circular hole pattern in the beam flanges demonstrated reliable performance.

Published: December 2019

The introduction of treated plant fibres into sand concretes leads to a reduction in density, improved ductility and thermal conductivity, and makes sand concrete an environmentally friendly and ecological material. The recovery of waste in this type of material allows the production of new ecological and sustainable materials used either in the new construction or in the rehabilitation of old buildings. In this context, a comparative study was based on the valorisation of marble and ceramic waste as sand in sand concrete made from straw fibres. To carry out this study, we introduced these wastes at substitution rates of 10% and 20%, separated and mixed, and studied the development of the properties of these concretes (density, workability, air content, compressive strength and bending tensile strength) and their behaviour with respect to durability (capillary and immersion absorption and chloride penetration). The study shows that the recovery of this waste as sand in sand concrete based on straw fibres gives satisfactory results. The chemical resistance, thermal conductivity and microstructure are under study, the results of which will be the subject of another publication.
Technical Aspects of Renovation of the 16th-Century Roof Truss
Authors: Nowogońska Beata
Published: December 2019

The main causes of damage to wooden structures in historic buildings are the effects of weather conditions and related aging processes. In the case of the roof truss of a 16th-century church in Lubów, the technical condition is additionally affected by leaking roof covering, damaged gutters, downpipes and flashings. Some elements of the wooden structure underwent biological corrosion, which lost its strength values. The roof truss of a 16th-century church in Lubów comes from the period of construction of the building. Due to the historic values of the structure of the truss, the renovation works do not intervene when the works would change its form, shape and type. The truss renovation is based on the assumption of maintaining original construction solutions, location of elements and cross-sections.

Authors: Leśniak Agnieszka , Górka Monika , Kargol Anna
Published: December 2019

One of the most important documents occurring in the investment process is the administrative decision: building permit. Obtaining it is often a time-consuming process in practice, associated with the need to attach to the application other required decisions and permits necessary for a positive consideration of the case. The procedure itself is not always a long-term process, as long as the investor makes sure to prepare a reliable application free of errors and irregularities together with the construction project and the required attachments. The purpose of the article is to analyze errors appearing in investors’ applications and attached project documentation required in the administrative procedure for obtaining a building permit in the light of the applicable provisions of Polish law.
Emporal and Spatial Variability of Rainfall in Modelling of Stormwater Outflows
Authors: Nowogoński Ireneusz
Published: December 2019

The article presents issues related to modeling of the rainfall-runoff phenomenon. As factors influencing the simulation results, the velocity and direction of precipitation relative to the drainage basin were indicated. The possibility of underestimating the cross-sections of rainwater channels as a result of overlapping rain wave directions and the dominant flow direction in the rainwater channel network was pointed out. The research results to date indicate a reduction in the symptoms of this phenomenon as the complexity of the channel network increases. The final verification was based on the actual catchment. Calculations were made using the Epa SWMM 5.1.013 software. The results are presented in a graphic form to illustrate the variability of stormwater outflow.

Authors: Karyadinata Henry Kusumas , Pudjihardjo Muhammad , Manzilati Asfi , Syafitri Wildan
Published: December 2019

Subject and purpose of work: This research was conducted to measure the influence of the Suramadu Bridge on the reduction of rural poverty and to determine the impact of production factors such as physical capital, natural capital, human capital and financial capital on poverty before and after the Suramadu Bridge began operating in Kabupaten Bangkalan.

Materials and methods: This study adapted the model used by Nashwari et al (2017) which was analysed applying Ordinary Least Square (OLS). The data from Village Potential 2007 and 2017 was used in the research.

Results: Many production factors in the village did not have a significant effect on the poverty reduction before the Suramadu Bridge began operating. After the Suramadu Bridge opened, it has had a significant negative impact on poverty. The number of farmers, rice fields, non-agricultural activities, superior products, skills facilities and credit facilities has a significant positive effect on the reduction of the poverty level.

Conclusions: The existence of the Suramadu Bridge has increased the influence of production factors in the villages on the poverty reduction in Kabupaten Bangkalan.

Commune Government as a Creator of Local Relations – The Local Innovation Context
Authors: Zwolińska-Ligaj Magdalena Anna
Published: December 2019

Subject and purpose of work: The objective of the study is to characterise the status and nature of local authorities’ relations with local communities and to assess the importance of local relations in the process of strengthening local innovation.

Materials and methods: The survey method was employed in the research and a questionnaire was sent to heads of communes /mayors via electronic means. The research material consisted of 105 questionnaire forms.

Results: There is a perceived imbalance in the development of interactions with social and economic actors to the disadvantage of interactions with economic sector representatives. Increasing local innovation rooted in the economic dimension of the development processes of the analysed local systems has been revealed to be of a relatively lesser importance. Local Action Groups are a major contributor to the development and innovation process, mainly in the social dimension. Local relations are not perceived by the representatives of local authorities as particularly important factors of regional innovation.

Conclusions: The analysis of the local systems revealed a need to increase the scale of activity of local government representatives as part of developing relations with the economic sector. Opportunities should be sought arising from building local partnerships aimed at the implementation of pro-innovative, multi-stakeholder projects, which will have a greater capacity to influence local development processes.
Protoeconomics in the European Middle Ages and Modern Times
Authors: Wójcicki Włodzimierz
Published: December 2019

Subject and purpose of work: The thesis presents an overview of the economic issues which existed in the European Middle Ages and modern times, prior to establishing classical economics.

Materials and methods: The thesis was prepared based on the literature review which included scientific publications and websites devoted to the economy, as well as to social and cultural changes. During the Middle Ages, the mere survival was no longer satisfactory for humans; the times saw the accumulation of wealth, which turned out to be a prerequisite for participation in social life.

Results: The initial intellectual narrative was dominated by canonists who studied the laws emerging from religious doctrines, gradually shifting their focus to philosophy, emphasizing the importance of research methods based on reason. Many universal ideas were introduced at the time.

Conclusions: a) The focus on the method used as a research tool accelerated the emergence of particular areas of scientific studies; b) Christianity constituted the cultural core in the medieval period;c) Theology, in conjunction with philosophy, constituted the source allowing for the emergence of social sciences.
“She Isn’t Going to Give Up”: Women’s Resilience in Monica Ali’s Brick Lane – A Feminist Reading
Authors: Ciocoi-Pop Ana-Blanca
Published: December 2019

While Monica Ali’s novel Brick Lane is most often analyzed from the vantage points of postcolonialism as a text dealing primarily with the plight of the Bangladeshi immigrant community in London, it is difficult, if not downright impossible, to overlook the crucial role women and feminine resilience (in the face of not only patriarchy, but also racism, religion and social unrest) play in the novel. In actual fact, the story can much easier be read as the plight of women in their quest for self-determination and identity than as a novel about cultural clashes in the multicultural metropolis. The present essay sets out to prove that feminism is actually at the forefront of Ali’s novel, and that the feminine characters in Brick Lane stand for a post-feminist reflection on the (still) gasping abyss between theoretical gender equality and real-life sexism.
“See the Child”: Representations of Childhood in Blood Meridian and The Road by Cormac McCarthy
Authors: Kimak Mădălina Larisa
Published: December 2019

This essay aims to illustrate the way in which the American writer Cormac McCarthy constructs the role of the children in his novels Blood Meridian, or the Evening Redness in the West and The Road to challenge the discursive reality elaborated by the two adult protagonists. The premise of this endeavor is that both Judge Holden and the man offer a logocentric vision of the world, which the young characters resist by questioning its validity and exposing its limits. The Post-Structuralist criticism of Jacques Derrida and Friedrich Nietzsche represents the theoretical foundation of the text analysis proposed below.
Cultural Encounters: Glimpses of the United States in Late Twentieth-Century Romanian Travel Narratives
Authors: Iancu Anca-Luminiţa
Published: December 2019

Travel narratives are complex accounts that include a significant layer of factual information – related to the geography, history, and/or the culture of a particular place or country – and a more personal layer, comprising the author’s unique perceptions and rendering of the travel experience. In the last thirty years of transition from a communist to a democratic society, the Romanians have been free to travel to any country they choose; however, during the communist period, especially during the 1980s, travelling to Western, capitalist countries, such as France, Great Britain, Canada, or the United States, was rather limited and fraught with complex issues. Still, Romanian travelers during that time managed to visit the United States, on diplomatic- or business-related exchanges, and published interesting travel stories of their experiences there. Therefore, this essay sets out to capture, from a comparative perspective, the impressions and encounters depicted by Radu Enescu inBetween Two Oceans(1986), Ion Dinu inTraveler through America(1991) and Viorel Sălăgean inHello America!(1992), with a view to analyzing how their descriptions and perceptions of two major urban spaces, New York City and San Francisco, reflect the complexity of the American social and cultural landscape in the late 1970s and mid-1980s.
Anxiety and Enjoyment in the Foreign Language Classroom
Authors: Mierzwa Ewelina
Published: December 2019

To balance the research that has been carried out on negative emotions, the researchers in the field of second language acquisition (SLA) have recently focused on the role of positive academic emotions and their role in the process of acquiring a foreign language (FL). The aim of the present article is to examine the relationships between foreign language enjoyment (FLE), foreign language classroom anxiety (FLCA) and students’ academic achievement in English in order to prove that these two emotions do not constitute opposite dimensions but may converge and diverge from time to time during the learning process. This article calls for a more dynamic approach to studying emotions and investigating whether and to what extent these two emotions may mutually shape one another and thus affect learners’ achievement in the foreign language classroom.
Communication and didactics, the difficult but needful symbiosis in higher education systems
Authors: Mustica Stefano
Published: December 2019

The first purpose of the university system is to deliver qualitative education through solid didactics/educational, but not many university structures seem really interested in the subject.

Sets of laws, measures, rules, and prescriptions of all kinds are in fact relegating it to a corner, making it less and less central and effective while also increasing the difficult to decipher, update and innovate it.

As a matter of fact, the issue of modernization of teaching methods has been tackled decisively by the European Commission, which has placed it among the priorities of its agenda. By acting in this way, EU is manifesting the conviction that a better quality for higher education will determine a growth in development and competitiveness not only for the Union itself but also for the individual universities that will define a strategy to improve the level of their teaching and learning and to give equal importance to research and teaching.

In its report on the theme of modernization and quality of teaching and learning, the European Commission summarizes its conclusions in 16 recommendations, including:

- the need for adequate teaching training for teachers;

- the need for the merits of teachers who make a significant contribution to improving teaching and learning methods to be recognized and rewarded.

But in order to achieve such quality prospects, it is necessary for university teachers to combine the knowledge of their discipline with specific communicative, cognitive and, more generally, relational skills. All this must become a principle of the university teaching of the future.

However, on a practical level, it is not uncommon to meet teachers who are not sufficiently attentive to these dimensions of the teaching-learning dynamic, failing to identify the “language” capable of transferring their theoretical/practical knowledge in the function of real learning of the student.

Actual tendencies in the evolution of financial sciences
Authors: Fetiniuc Valentina , Luchian Ivan
Published: December 2019

Present article places in the center of attention finance as a science, which examines all relations of distributive and redistributive nature between different economic actors related to the formation and use of monetary resources and funds. Finance has a relatively long history of development, with ongoing substantial transformation. The results of generalization of related studies show that there are three periods in the genesis of finance as a science. First is the scientific status. Second - is related to the transition to the scientific process. The third is the scientific or rational. The fourth period is related to the formation of the neoclassical theory of finance. This transformation takes place so far under the influence of a new factor related to the establishment of the post industrial type economy. Equally important was the process of internationalization and then - of globalization. Last has a double impact. On one side, there is the consolidation of the financial system scientifically accepted as the single global vision on different areas of financial sciences. From the other hand, there is the process of adaptation and development of scientific concepts under the influence of new financial and economic conditions imposed by the superlative form related to globalization. The development of the financial sciences is also related to the need to solve a large complex of important problems of a financial nature, which will ultimately lead to the change of the global financial picture.

Published: December 2019

Apis mellifera filamentous virus (AmFV) is a large double stranded DNA virus of honey bees and its prevalence and relationship with other parasites is poorly known. Samples consisted of fifty-one adult bees belonging to eight native species collected using entomological nets in six provinces of Argentina, from 2009 to 2018. Total genomic DNA was extracted from individual bees and a 551 bp fragment of the Bro-N gene of AmFV was amplified by qPCR. In the present work we have reported for the first time both the presence and the wide geographic distribution of AmFV in Argentinian species of native bees. This is the first report of the presence of this virus associated with Xylocopa atamisquensis, X. augusti, X. frontalis, X. spendidula, Bombus pauloensis and Peponapis fervens. Detecting pathogens that could threaten native bee health is of outmost importance to generate both conservation and management strategies.
Depression and Metabolic Syndrome: Two Sides of the Same Coin
Authors: John George , Asghari Mona , VP Vipin , Eapen Valsamma
Published: December 2019

This aim of this review was to examine the relationship between metabolic syndrome (MetS) and depression, which is complex and multifaceted with many inter-related factors includinggenetics, lifestylefactors, environmentalfactorsand other psychological factors at play. There is some evidence to suggest that depression may lead to the development of cardiovascular disease through its association with MetS. It has also been suggested that depressive symptoms may be a consequence rather than the cause of the MetS, as obesity and dyslipidemia have been shown as predictive of depressive symptoms. Thus, the relationship between MetS and depression seems to be a two-way street and bi-directional just as the two sides of the same coin.

Gangliocytic paraganglioma (GP) is an uncommon finding in the periampullary region of the duodenum. In the Department of General and Digestive Surgery of the Albacete University Hospital Complex, a 45-years-old patient was diagnosed with a 17x13mm hypervascular nodular lesion in the descending part of the duodenum during an examination for hepatic hemangiomas. Ampullectomy was performed, followed by a favourable postoperative period. Histological analysis proved GP. There were no involvement of lymph nodes and a malignancy potential, so the clinical and radiological follow-up opted. In conclusion, because such tumours have unpredictable behavior, we recommend local resection of the tumour, except in cases in which local or ganglionic progression is suspected or confirmed, and thus cephalic pancreaticoduodenectomy (CPD) and lymphadenectomy are suggested.

Published: December 2019

Recently, the important role of matrix metalloproteinases (MMPs) has been identified in follicular development and subsequent ovulation. Although the role of MMP in ovarian tissue remodeling during folliculogenesis has been well studied, the relationship between matrix protease activity and their inhibitors - Tisue inhibitors of matrix metalloproteinases (TIMP) and aging of the oocytes is still unclear. The present study aimed to establish the probable relationship between the expression levels of MMP-2 and TMP-1 and TIMP-2 in follicular fluid with the degree of oocyte maturity and quality. Follicular fluids from 20 women collected on the day of follicular puncture were tested for the presence of MMP-2, TIMP-1, and TIMP-2 using enzyme-linked immunosorbent assay (ELISA). The oocytes obtained were described in terms of maturity, morphology, and fertilization, as well as the embryo’s quality and rate of development. MMP-2 was significantly higher in follicular aspirates in the first prophase of meiosis - germinal vesicle (GV), compared to aspirates with first metaphase (MI) (p=0.011) and second metaphase (MII) of mature oocytes (p=0.010). The MMP-2/TIMP-1 ratio was significantly higher for GV compared to M1 (p=0.011), M2 (p=0.006) and atretic oocytes (p=0.032); (F(3, 71)=2.909, p=0.040). Based on our results, we can conclude that MMP-2 concentration in follicular fluids during the IVF / ICSI procedure had a significant relationship to oocyte maturation levels. It was significantly higher in the case of immature oocytes. On the other hand, oocytes with normal morphology were associated with a significantly higher MMP-2 concentration in follicular fluids.

Published: December 2019

We studied the incidence and causes of transition disturbances in the first 30 minutes of life in full-term newborns. This one-year study was retrospective and included 1147 full- term live-born neonates without life-threatening congenital anomalies and surgical complications. They were divided into four groups: 0 (with normal transition), 1 (resuscitated without endotracheal intubation), and 2 (intubated); A (without underlying maternal, obstetric or fetal/neonatal problem, with adequate for GA eight and from single birth) and B (with one or more of following: underlying maternal, obstetric or fetal/neonatal problem, SGA or LGA, from multiple pregnancies).

Of the newborns, 9.1% of required resuscitation and 1.6% - extensive resuscitation with intubation. The groups significantly differed in the incidence of underlying maternal, obstetric, or fetal/neonatal problems. Resuscitated babies were born via Caesarean section (CS), in abnormal presentation (PaN) and by vacuum extraction or forceps (V/F) predominantly. The highest incidence of the small for gestational age (GA) babies – SGA, was detected in Group 2. Twins and large for GA (LGA) had prevalence in Group 1. Resuscitation was necessary for 18.1% of CS-delivered babies. V/F and PaN lead to the highest need for intubation. According to our data, every 10th of the full-term neonates required assistance in the fetal-to-neonatal transition. The causes could be diseases of the mother or fetus/newborn, multiple births, SGA, or LGA. A compromised medical decision about the time and way of delivery may result in iatrogenic transition disturbances.

Published: December 2019

The present study aimed to evaluate the impact of factor V Leiden (FVL) polymorphism within the reproductive problems encountered by patients with polycystic ovary syndrome (PCOS). A total of 92 female patients with PCOS and 101 healthy controls were included in the study. Clinical and laboratory parameters were examined. The full history of each patient was taken. Single nucleotide polymorphism rs6025 in F5 was genotyped in PCOS patients and compared to the genotype frequency of the healthy controls. The data were analysed for correlation with infertility and pregnancy loss in PCOS patients. The prevalence of FVL polymorphism was higher, however not significantly, in PCOS patients compared to that of the control group (respectively OR=2.238, 95 % CI 0.777±6.449, p=0.104). The carriers of FVL polymorphism showed a higher rate of primary infertility (30.0% versus 12.5%, OR=3.143, 9 % CI 0.686±14.388, p=0.047) and their total reproductive failure rate was higher (60.5% versus 47.2%, OR=1.819, 95% CI 0.632±9.259, p=0.117). Carriage of FVL polymorphism in PCOS patients is associated with primary infertility and a presumed cause of the further investigations needed to understand the impact of FVL on PCOS. Carriage of FVL polymorphism in PCOS patients is associated with a higher rate of primary infertility, which draws attention to the role of this factor in the aetiology of the PCOS-related subfertility. Further investigations are needed to understand the impact of FVL on PCOS.

Published: December 2019

Schizophrenia is associated with basic neurocognitive deficit- ineffective space-time information assessment, leading to ineffective judgment and planning of behaviour. Our study aimed to examine and compare the psychomotor speed and number of errors in patients with paranoid schizophrenia (PS), first-degree relatives (FDR) and healthy controls (HC). One-hundred-eight patients with PS, 58 with FDR and 60 HCs were examined via Trail Making Tests (TMT) A and B. The influence of other additional factors as The Positive and Negative Syndrome Scale (PANSS), demographics and education were additionally assessed for PS. Statistical analysis was done using Excel 2010, Statgraphics 5.0+ and SPSS 20. All results were interpreted at 95% confidential level. PS showed most unsatisfactory performances on TMT A and B, as compared to others (p=0.0001). However, FDR differed from HC only in TMTB performance (p=0.0241). The most significant impact in PS group included ageing, education, PANSS and negative syndromes, and syndromes of disorganization. PS showed a significant decline of psychomotor speed and executive functioning, although FDR had average results in TMTB, compared to PS and HC. The above results determined both detentions as endophenotype markers for PS. Additional risk factors for decline include ageing, low education and high PANSS results.
Calibration, Validation and Performance Evaluation of Swat Model for Sediment Yield Modelling in Megech Reservoir Catchment, Ethiopia
Authors: Assfaw Abebe Tarko
Published: December 2019

Intensive agricultural practice in Ethiopian highlands results in increasing rates of soil erosion and reservoir sedimentation. The estimation of sediment yield and prediction of the spatial distribution of soil erosion on the upper Megech reservoir catchment enables the local governments and policymakers to maximize the design span life of the Megech reservoir through implementing appropriate soil conservation practices. For this study, the sediment yield was estimated and analyzed through hydrological modeling (SWAT). The simulated outputs of the model show that the mean annual surface runoff was 282 mm and the mean annual streamflow was 153 m3/s. Similarly, 12.33 t/ha mean annual total sediment load gets into the Megech reservoir. The model performance standard used to evaluate the model result indicates that the model was superior in performing the trend of runoff and sediment yield in both calibration and validation periods. Finally, the most erosion vulnerable sub-basins that could have a significant impact on the sediment yield of the reservoir were identified. Based on this, sub-basin 7, 25, 27, 18 and 29 were found to be the most erosion sensitive areas that could have a significant contribution to the increment of sediment yield in the Megech reservoir. Considering the land use, soil type, slope, and relief of erosion vulnerable sub-basins cut off drains, fallow land, contour ploughing, Fanya juu terraces, soil bunds combined with trenches and trees could be the possible management strategies to reduce the sediment yield in the catchment.

Lowland Slovak youth literature and its interpretational and educational aspects (within and outside the school)
Authors: Šenkár Patrik
Published: December 2019

An integral part of the Slovak cultural context is also Lowland Slovak literature, which includes certain areas of Hungary, Romania and Serbia. The paper outlines the partial development of Slovak youth literature in these regions. It gradually characterizes the most important aspects of diachrony of this segment of writing (in a certain chronotope that is bound to selected prototexts). Based on objective-subjective interpretations of three emblematic works of this context, it highlights - as a certain typology - not only the general / universal, but also the specific / particular (that is particularly relevant to the context) in intra- and intercultural relations. It accentuates the literary tradition, which is still a useful source of realistic short stories and novels for child percipients in these diasporas. It also traditionally and innovatively points out the typical features of teaching in individual national-minority schools in the mentioned countries. Methodologically (but also practically) it is, of course, based, on thematic, motif related, etc. aspects of the analyzed (selected) works and their possible reflection in school education and learning environment. Finally, the use of language / features / motifs / aspects / procedures is concretized in specific conditions outside the physical boundaries of the homeland as a kind of perspective on the correlation of the difficult process of cultural education itself.
Teacher-student interaction and management practices in Pakistani English language classrooms
Authors: Ahmad Muhammad , Shakir Aleem , Siddique Ali Raza
Published: December 2019

This study aimed to investigate the amount and type of teacher-talk, frequently asked questions and feedback provided by the teacher on learners’ performance in a language classroom. For this purpose, a lecture was recorded from a secondary level English language classroom of a public sector school and interpreted in the light of teacher-student interaction and classroom management model by David Nunan. Results revealed that the maximum amount of time (i.e. 80.1%) was consumed by the teacher which was appropriate. However, certain deviations from classroom management principles were also observed regarding frequently asked questions (i.e. 50% of the total questions were elicitation questions) and the feedback (it was ‘romantic’ in nature). Moreover, wait-time was sufficient but it was of no use to the learners. The study concluded that classroom practices did not conform to the principles therefore, it proposed to ask questions and provide feedback appropriately.
Satisfaction with the lives of elderly nursing homes residents
Authors: Trybusińska Dorota , Saracen Agnieszka
Published: December 2019

Introduction. Ageing of societies is a process apparent in nearly all countries worldwide. Many families will not be able to provide care services for the elderly, the burden of care will fall mainly on public and private institutions. This puts employees of nursing homes in front of numerous challenges in order to provide seniors with improvement of their life satisfaction.

Aim. The purpose of the study was to assess the life satisfaction of elderly nursing home residents in the Mazovian region and to demonstrate variables that affect it.

Material and methods.. The research was carried out in 2018 among the 250 elderly nursing home residents from Mazovia. During the test, a diagnostic survey method and a questionnaire technique were used. The research tool was the Satisfaction With Life Scale (SWLS), Katz’s Activities of Daily Living Scale, Hodgkinson’s Abbreviated Mental Test Score, Basic Hope Inventory (BHI-12), Acceptance of Illness Scale (AIS), and the authors’ survey questionnaire.

Results. Among the respondents, the dominant group included people with low life satisfaction (42.8%). A statistically significant relationship was found between life satisfaction and the age of the respondents and selected psychometric scales. There was no such correlation for the level of mobility, duration of stay at the nursing home and the size of the inhabited facility.

Conclusions. Elderly people living in nursing homes from Mazovia enjoy life satisfaction at a low and average level. The results distinguish three groups of residents exhibiting a lower satisfaction with life, namely, new arrivals, the oldest, and suffering from a minimum of one illness. Nursing home personnel who deal with patients on an everyday basis should aim to improve their life satisfaction.

The aim of the current research was to study the radiation shielding properties of polyurethane-based shielding materials filled with B4C, BeO, WO3, ZnO, and Gd2O3 particles against fast neutrons. The macroscopic cross sections of composites containing micro- and nanoparticles with a diameter of 10 µm and 50 nm were calculated using MCNPX (2.6.0) Monte Carlo code. The results showed that adding nano-scaled fillers to polyurethane matrix increases attenuation properties of neutron shields compared to micro-scaled fillers for intermediate and fast neutrons. Among the studied composites, WO3 and Gd2O3 nano-composites presented higher neutron cross section compared to others.

Advanced jet training still relies on old concepts and solutions that are no longer efficient when considering the current and forthcoming changes in air combat. The cost of those old solutions to develop and maintain combat pilot skills are important, adding even more constraints to the training limitations. The requirement of having a trainer aircraft able to perform also light combat aircraft operational mission is adding unnecessary complexity and cost without any real operational advantages to air combat mission training.

Thanks to emerging technologies, the JANUS project will study the feasibility of a brand-new concept of agile manoeuvrable training aircraft and an integrated training system, able to provide a live, virtual and constructive environment. The JANUS concept is based on a lightweight, low-cost, high energy aircraft associated to a ground based Integrated Training System providing simulated and emulated signals, simulated and real opponents, combined with real-time feedback on pilot’s physiological characteristics: traditionally embedded sensors are replaced with emulated signals, simulated opponents are proposed to the pilot, enabling out of sight engagement. JANUS is also providing new cost effective and more realistic solutions for “Red air aircraft” missions, organised in so-called “Aggressor Squadrons”.

Published: December 2019

The paper presents the validation procedure of the model used in the analysis of the composite blade for the rotor of the ILX-27 rotorcraft, designed and manufactured in the Institute of Aviation, by means of numerical analyses and tests of composite elements. Numerical analysis using finite element method and experimental studies of three research objects made of basic materials comprising the blade structure – carbon-epoxy laminate, glass-epoxy composite made of roving and foam filler – were carried out. The elements were in the form of four-point bent beams, and for comparison of the results the deflection arrow values in the middle of the beam and axial deformations on the upper and lower surfaces were selected. The procedure allowed to adjust the discrete model to real objects and to verify and correct the material data used in the strength analysis of the designed blade.

This article has a theoretical and experimental character. It presents the characteristics of two main thermoplastics used in the aerospace industry – poly ether ether ketone (PEEK) and poly phenylene sulphide (PPS). The selected materials are compounds for the production of thermoplastic polymer matrix composites. The paper presents a literature review of the application of thermoplastic polymer matrix composite materials in aviation. Additionally, the paper focuses on the characteristics of carbon fibre-reinforced polymer (CFRP) which plays an important role in the production of aerospace components. Testing methods have been chosen on the basis of the type of composite matrix. The article contains the most important mechanical properties and general characteristics of thermoplastics used as a matrix for CFRP type composites used in the aerospace industry. Individual test procedures which allow for the evaluation of mechanical properties of composite materials on a thermoplastic polymer matrix, have been described. Mechanical tests such as static tensile test and bending of short beams were carried out in order to examine CFRP composites.

The article presents research conducted with the project: ‘Additive manufacturing in conduction with optical methods used for optimization of 3D models’’ [2]. The article begins with the description of properties of the materials used in three different additive technologies – Fused Deposition Modelling (FDM), Selective Laser Sintering (SLS) and Material Jetting (MJ). The next part focuses on the comparative analysis of macro- and microstructure of specimens printed in order to test selected materials in additive technologies mentioned above. In this research two types of specimens were used: dumbbell specimens and rectangular prism with hole specimens. In order to observe macrostructure specimens, they were subjected to load test until it broke. In the case of observing microstructure, they were cut in some places. Each of described additive technologies characterizes by both different way of printing and used materials. These variables have a significant influence on macro- and microstructure and fracture appearance. FDM technology specimens printed of ABS material characterized by texture surface appearance. SLS technology specimens printed of PA12 material characterized by amorphous structure. MJ technology specimens printed of VeroWhite Plus material characterized by fracture appearance which had quasi- fatigue features. The microstructure of these specimens was uniform with visible inclusions.

Published: December 2019

O presente artigo tem como proposta central apresentar reflexões em torno dos conceitos de experiência, participação política e militância. A pretensão é por promover uma interlocução entre as potencialidades formativas inerentes aos sujeitos inseridos e engajados em experiências participativas e de militância em movimentos sociais na contemporaneidade. O arcabouço teórico aqui debatido subsidiou uma pesquisa em Educação que investigou as experiências participativas de um grupo de jovens militantes que atuavam em uma ocupação urbana, buscando compreender as dimensões formativas desse tipo de engajamento. Nesse mesmo contexto, foi estabelecido um debate com foco na complexidade da sociedade atual e nas potencialidades e possibilidades participativas/formativas proporcionadas pela realidade social, bem como uma discussão em torno dos conceitos de sujeito, indivíduo e ator.
CONTRIBUTOS PEDAGÓGICOS DO PADRE PEDRO Mª AGUILAR AO ENSINO DOS SURDOS-MUDOS EM PORTUGAL (SÉC. XIX)
Authors: Martins Ernesto Candeias
Published: December 2019

Pedro Mª Aguilar (1828?-1879) foi um pedagogo dedicado ao ensino da surdez. Este sacerdote, nascido em Pinhel, foi capelão, professor de moral e bibliotecário na Escola Normal de Marvila (Lisboa), desenvolvendo nesse período as suas leituras e investigações na área da educação especial (domínio dos surdos-mudos), engrandecendo a pedagogia diferencial no ensino. Fundou Instituto de Surdos-Mudos em Guimarães (1870), que viria a encerrar por falta de recursos financeiros. Em 1877, recebe subsídio da Câmara Municipal e funda Instituto de Surdos-Mudos do Porto, extinto em 1887, sob as ordens do seu sobrinho, Eliseu Aguilar. Analisaremos, de forma hermenêutica e reflexiva, os contributos deste educador, no âmbito da educação especial e pedagogia diferenciada. Utilizámos várias fontes primárias (arquivos, centros de documentação) e secundárias. Padre Aguilar foi um pedagogo, de pouca obra escrita, que aprofundou o método de ensino sinais metódicos e perfilou métodos intuitivos nesse ensino relevantes na época.

Quarries of different types and uses and quarried materials can be foundeverywhere in the Kurdistan region, Iraq. The main quarries are those of limestone used for cement production, and they are of multiphases and are well designed. Other quarries are randomly located without any scientific aspects; these are used for local purposes, mainly for aggregates. However, they are all polluting the environment (air, water, and soil) in different intensities and moods.
