Flexural Behaviors of Modified Recycled Aggregate Concrete Reinforced with Pultruded GFRP
Authors: Ismail Sallehan , Ramli Mahyuddin
Published: November 2022

Corrosion of steel reinforcement in underwater concrete structures continues to be a problem in the modern era. The possibility of employing pultruded glass fibre reinforced polymer (GRFP) I beams to replace traditional steel reinforcement in an encased beam is still being explored. The purpose of this research is to further investigate the effects of incorporating treated recycled concrete aggregate (RCA) and discrete synthetic fibres, specifically Polyolefin (PO) and Fibrillated Polypropylene (PP) fibres, in the production of concrete beam reinforced with GFRP I beam for underwater construction. Five beams were constructed and tested in this investigation using a four-point loading arrangement. The load–deflection curve, stress–strain curve, and initial and ultimate fracture loads are all included in the test parameter set. The results indicate that treating RCA and fibres greatly increases the flexural capacity of modified recycle aggregate concrete (RAC) beams compared to unmodified RAC beams.
Spray Pyrolyzed Praseodymium Doped SnO2 Thin Film with Fast Response to LPG: Analysis Based on Microstructural Features
Authors: Deepa S. , Krishnan Prasanna Kumari , Thomas Boben
Published: November 2022

Praseodymium (Pr) doped (0.1 to 6 wt. %) nanostructured SnO2 thin films are prepared via nebulizer assisted spray deposition process at a deposition temperature of 320 °C. The analyses show that the films grow in (110), (301) and (310) preferred orientations. The fabricated sensing films are exposed to LPG at 500 ppm concentration and at different operating temperatures. In 500 ppm of LPG, at an operating temperature of 350 °C, a commendable sensor response of 99 % with fast response time of 9 s and recovery time of 11 s is shown by 1wt.% Pr doped film, which is appreciable compared to pristine SnO2 film. The sensor response reduces at lower operating temperatures. Microstructural investigations justify the gas sensing performance of 1 wt.% Pr doped SnO2 thin film. Raman and photoluminescence studies give an insight into oxygen vacancies and trapped states that have a crucial influence on gas sensing.

Published: November 2022

In this paper, the influence of the surface roughness of build plates as well as the process parameters laser power, scan speed and exposure curing time on the bonding of additively manufactured components made of TiAl6V4 to the build plates is analyzed. These analyses are carried out with build plates made of Titanium Grade 2 and AlMgSi0.5. The analyses show that higher surface roughness leads to lower bending strength and thus poorer bonding of components on the build plate. In addition, it is shown that the bending strength normalized to the bonding surface decreases at high laser power, especially at high scanning speeds. Furthermore, multiple exposure results in lower flexural strength.

Published: November 2022

The plankton community plays a significant role in the stability of coastal ecosystems. They serve as key players in marine food webs. The present study investigated the plankton diversity in coastal waters near Kalu Ganga river mouth. Six sampling locations were chosen randomly, three along the right side of the coastline (CR1-CR3) and three along the left-side (CL1-CL3) from the river mouth. Zooplankton and phytoplankton at each location were sampled from September 2020 to February 2021 using a 55μm plankton net in surface waters on a monthly basis. Plankton were morphologically identified to the nearest possible taxonomic level. The Shannon-Weiner diversity index (H) and Simpson's Index of Diversity (SID) were calculated to determine plankton diversity. The number of phytoplankton species found during the wet months (September-October) and dry months (January-February) were 62 and 68 respectively, while a similar number of zooplankton species (43) were recorded in both periods. Altogether, 81 phytoplankton species and 53 zooplankton species were identified during the research period. Bacillariophyta (72%) and Copepods (68%) were identified as the dominant phytoplankton and zooplankton groups respectively. Dinoflagellates including, Peridinium sp., Protoperidinium sp., Ceratium sp., Noctiluca sp., Gonyaulax sp., and Alexandrium sp., which are well-known to form harmful algal blooms (HABs) accounted for 17%. Chlorophyta and Cyanophyta were less dominated and found only during wet months at nearest sampling locations (CL1 and CR1) to river mouth. Rotifera (11%), foraminifera (9%), protozoa (10%) and ichthyoplanktons (<1%) were also reported. The H and SID values for plankton were recorded to be between 2.7 to 3.1 and 0.90 to 0.96 respectively. The both values were not significantly different (p>0.05) between wet months and dry months at each location. According to the H and SID values, the study area has a moderate-high level of plankton diversity. Further research should be conducted to determine the temporal and spatial variation of plankton diversity in the study area.
Artificial Deprivation of Human Life: The Legal, Moral and Religious Controversy of Euthanasia and Assisted Suicide
Authors: Nissanka Ruwini Uthpala
Published: November 2022

Euthanasia or assisted suicide could be defined as the practice of artificial deprivation of human life to end unbearable and incurable suffering of a terminally ill person. Medical Historians believe that ancient Greeks and Romans were in support of the concept of mercy killing rather than denying the whole notion. While opponents and proponents of euthanasia have not arrived at a mutual understanding yet, Oregon, USA was the first state to decriminalize euthanasia while Netherlands and Belgium were the first nations to legalize assisted suicide. While many countries across the globe comprising a few in Asia including Japan, have adopted similar means, Sri Lanka remains inflexible when it comes to this subject. Any sort of intentional taking of human life is considered an offence in Sri Lanka and Article 296 of the penal code prescribes death penalty for such actions which amount to the offence of murder. Suicide is also considered an offence under article 299 of the penal code and a person who aids and assists suicide could be penalized with capital punishment though Sri Lanka has adopted a de-facto moratorium on executions since 1976. The only instance where Sri Lankan law allows wilful ending of human life is under section 303 of the penal code where medical termination of pregnancy is possible strictly under the condition of preservation of mother’s life. This qualitative research was carried out as a literature-based, comparative study, and it concentrates on the concept of euthanasia, assisted suicide, the legal, moral, and religious controversy it has led to with examples from other countries while considering the possibility of decriminalizing physician-assisted suicide in Sri Lanka for terminally ill patients, under stringent conditions and suggesting in favour of voluntary passive euthanasia.
A Literature Review on Factors Affecting the Academic Performance of Undergraduate Nursing Students in a Sri Lankan University Context
Authors: Sandharenu K. L. K. T. D. , Neranja A. G. K.
Published: November 2022

This article explores various cutting-edge strategies Sri Lanka might use to modernize its nursing curriculum in order to tackle contemporary issues. Employers search the world over for nursing experts who have the skills necessary to meet the modern requirements of the world healthcare system. It is now vital to enhance nursing education in order to extend its focus, deliver more remarkable patient care, and increase the retention and persistence of the students. Nursing students in Sri Lankan institutions place a premium on academic achievement. Meanwhile, many factors that impact nursing students' academic success have been studied, yet many issues still exist. The current study employed a review technique to examine the literature on undergraduate nursing students’ academic performance in a Sri Lankan university context, as well as numerous factors influencing nursing students' performance. The relevant literature for the article was gathered from the Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, and Google Scholar. The search was restricted to the English language. The paper illustrates how both internal and external factors have an impact on academic performance and outlines measures to enhance the grades of nursing students. Internal factors include student-related factors, while external factors include teacher-related, institutional-related, and home-related factors. The student-related factors were investigated by allowing the students themselves to understand the factors and implement actions to improve their academic performance. Teachers play a major role in enhancing performance. This could be done by allowing them to identify problems encountered by students that impact their performance. The relevant educational institutions can promote different workshops and activities to enhance the thinking skills of students, as well as help teachers, understand the influences of their student’s preferred learning methods that will enhance their performances. Parents can identify the matters that pertain to the studies of their children and enhance their performance by giving them support. The study has the benefit of identifying the factors affecting performance and giving suggestions for producing intelligent and skilled nursing graduates for the nation.

Published: November 2022

The tire industry in Sri Lanka shows excellent potential for the development of the economy with a substantial contribution to export income. Therefore, the main objective of this study is to examine the determinants and impact of tire export income in Sri Lanka. Secondary data was obtained from Central Bank in Sri Lanka and United Nations Statistical Office covering the period from 1989 to 2018. Unit root test, simple and multiple regression Co integration analysis, Error Correction Model, and Granger Causality tests were used for analysis. The study found a long-run causality between GDP, Global market price for rubber, Exchange Rate, and Inflation with tire export income. The causality test suggested a causality running from export income to GDP. However, there is no causality running between GDP and export income. According to regression results, GDP, inflation, and exchange rate significantly determined the tire export income in Sri Lanka. Further, inflation and exchange rates were negative, and the GDP was positively influenced by the tire export income. While Domestic and Global Market prices for rubber did not show a significant influence on the tire export income. Government should maintain favourable macroeconomic policies, especially monetary policies which enhance the stability of the economy.

Despite a multitude of vulnerabilities of textual passwords, they are more likely to remain widespread since no scheme has become able to come close to providing all desired benefits. Among those vulnerabilities, peeping attacks are recognized as a real threat but, yet remain much unexplored. Most often, applications and systems use textual passwords for authentication, without considering the threat of peeping attacks. Our study provides the first numerical evidence of strength reduction to represent the impact of the attack. We introduce a novel authentication scheme that is conceptually different but purely text-based, as an endeavour towards strengthening textual passwords against the impact of peeping attacks. An experimental approach was used to collect data, simulating a peeping attack. Researchers intended were to provide an idea to the community, at the level of which the strength of a password can be reduced. This vulnerability is something crucial, yet haven't focused enough. Having such an understanding is desirable, as it can provide an image on the impact that these attacks can have on strength of textual passwords.

Published: November 2022

Purpose We aimed to investigate the feasibility of four criteria on oligometastasis (OM) concerning clear survival benefits of local therapy (LT) during tyrosine kinase inhibitor (TKI) treatment in non–small cell lung cancer (NSCLC).Materials and Methods This single-center, retrospective study included patients with advanced NSCLC who received LT because of OM during TKI treatment at Asan Medical Center from January 2011 to December 2020. At the application of LT OM was classified according to four criteria: TNM, European Organization for Research and Treatment of Cancer Lung Cancer Group (EORTC-LCG), National Comprehensive Network (NCCN), and ORGAN. We compared survival outcomes between patients with and without OM.Results The median overall survival of the 117 patients included in the analysis was 70.8 months (95% confidence interval [CI], 56.6 to 85.1). The patients with OM meeting all four criteria (hazard ratio [HR] with 95% CI of TNM criteria 0.24 with 0.10-0.57; p=0.001, EORTC-LCG criteria 0.34 with 0.17-0.67; p=0.002, NCCN criteria 0.41 with 0.20-0.86; p=0.018 and ORGAN criteria 0.33 with 0.18-0.60; p < 0.001) had significantly longer survival compared with patients who did not after adjusting for confounding factors. Furthermore, increasing the number of extra-thoracic metastatic organs to two or more were independent predictive factors for worse survival outcomes (2 organs: HR, 3.51; 95% CI, 1.01 to 12.14; p=0.048; 3 organs: HR, 4.31; 95% CI, 0.94 to 19.73; p=0.060; 4 organs: HR, 24.47; 95% CI, 5.08 to 117.80; p < 0.001).Conclusion Patients with OM defined by all four criteria showed prognostic benefits from LT during TKI therapy.

Student Motivation in Learning Mathematics in Technical and Vocational Higher Education: Development of an Instrument
Authors: Saadati Farzaneh , Celis Sergio
Published: November 2022

Mathematics is a challenging subject for most students in technical and vocational institutions. The institutions apply great effort towards developing mathematics knowledge and skills, mainly by influencing students' motivations. This study tries: (1) to present evidence for the validity of an instrument for measuring students' motivational beliefs as their beliefs, self-efficacy, and intrinsic-extrinsic goal orientations regarding mathematics; (2) to explore the relationship between institutional context and the instrument’s scores as students’ motivational beliefs. The data collected from 1,239 students from two different Chilean institutions were analyzed. The psychometric analysis provided evidence of the reliability and validity of the instrument. The instrument suggests differences in the level of motivational beliefs associated with students' age and the type of institutions. The instrument allows educators to study the relationships between motivational beliefs and the institutional context of technical and vocational schools. It can also be used for the prediction of student success in their mathematics course by the understanding of their motivational beliefs towards mathematics.
The Impact of COVID-19 Distance Learning on Students’ Math Anxiety: An Exploratory Study
Authors: Doz Daniel , Doz Eleonora
Published: November 2022

In spring 2020, the COVID-19 pandemic forced a rapid shift to distance learning worldwide. Although recent research has focused on the impact that this transition had on students’ education and well-being, little has been done in particular on math education and on math anxiety (MA). Since MA is believed to be linked to the teaching methods, it could be hypothesized that the new learning environment affected MA levels. Thus, this study investigated whether students’ levels of MA evaluated before and during the first wave of the pandemic changed as a consequence of the distance learning implementation. Moreover, we were interested in investigating whether students’ satisfaction with the teaching methods, their effort in math, and their academic achievement were correlated to MA before and during the COVID-19 distance learning. Participants were 117 Italian middle and high school students. No significant differences between pre- and mid-pandemic MA were found when considering the entire sample. Analyzing separately, results indicated that high-MA students reported significantly lower MA levels during distance learning, however no difference was observed for moderate- and low-MA individuals. Furthermore, satisfaction with the teaching methods, effort in math, and math achievement were negatively correlated with MA, both before and during distance education.
Pre-Service Teachers as Researchers: A Mentorship Model
Authors: Kara Melike , Corum Kimberly
Published: November 2022

In this paper, we share a mentorship model we developed and implemented while collaborating with pre-service teachers (PSTs) on their Model Eliciting Activity projects and the outcomes of the mentorship model in terms of PSTs’ growth as teachers as well as researchers. For their projects, PSTs designed and developed their own mathematical modeling tasks and later analyzed student work collected during task implementations to better understand their students’ reasoning. The PSTs’ reflections were collected to assess the effectiveness of the program and to report their professional growth. The PSTs who participated in this mentorship model identified core teaching practices (e.g., questioning, facilitating discussions) and they improved their knowledge of student thinking and reasoning. They were also able to analyze rich data and identify trends in student learning. The findings from this study affirm that engaging in undergraduate research provides PSTs with opportunities to improve their teaching practice as well as their understanding of research processes.
The Role of New Social Ties in Creating Meaningful Life
Authors: Tapani Annukka , Sinkkonen Merja
Published: November 2022

This article suggests that communities and social ties support the feeling of being meaningful. The theoretical concepts discussed here are social capital, community, and new forms of social ties. The data consists of 969 answers from citizens of different ages from three cities. Despite the possibilities of new global social ties, Finns seem to be quite traditional when it comes to a meaningful life: the sources of communality are “old communities” such as work, work communities, families, and relatives. The self-determination theory (Deci Ryan, 2000) fits well with Finns: it is important to recognize personal competence. Nevertheless, it is not enough to be competent: people need to be related to others but also have enough autonomy among others. After covid-19 and the period of enforced remote work, we need new ways to build communality and relatedness in creating and maintaining traditional and new social ties.

Az infokommunikációs technológiák folyamatos fejlődésével egyre inkább átjárja mindennapi pedagógiai munkánkat a digitalizáció és a digitális pedagógia. Tanulmányunk célja az, hogy a tanulás-tanítás folyamatában azonosítsuk és megnevezzük azokat a tanulásmódszertani, didaktikai elemeket, ahol a digitális pedagógia által használt eszközök vagy programok megjelenhetnek. Ezekből is kiemelve a tanári szerepek változását, azt a fajta szemléletmódot, mely eltér a hagyományos frontális technikától, és valami újat (majd láthatjuk, hogy ezek a módszerek nem mindig újak), érdekeset, más szemlélettel telit hoz az osztályterembe vagy a virtuális osztályterembe. Illetve a célunk az is, hogy elméleti és gyakorlati keretet adjunk a digitális pedagógia által kínált eszköztárnak, és ennek tükrében újradefiniáljuk a tanári szerepeket. Munkánk fő vezérfonalát a Szűts Zoltán által írt A digitális pedagógia egységes elméleti kerete és alkalmazása a tanítás és tanulás folyamatában doktori értekezése alapján fűztük fel és bontottuk ki.

Tanulmányunk a pedagógiai innovációk egyre nagyobb kutatói és szélesebb társadalmi érdeklődést kiváltó kérdéséhez a konstruktivista tanuláselmélet felől közelít. A tanuláselméleti megközelítés az eddig főképp a tág értelemben vett szervezeti működésre koncentráló vizsgálódásokat meggyőződésünk szerint releváns új szempontokkal egészítheti ki. A konstruktivizmus gondolatmenetünk középpontjába állított adaptivitásfogalmának segítségével az innovációk tervezésének, beválásának és elterjedésének problémája új módon válik felvethetővé. A kérdezés fókusza a jóság objektív kritériumairól az érintett személyek (tanárképzők, pedagógusok, tanulók, szülők stb.) előzetes tudásrendszereire, ismereteire, meggyőződéseire, tapasztalataira helyeződik át, amelyek az eredményesség növelését célzó újításnak vagy éppen az újítással felváltani kívánt gyakorlatnak az adaptivitás tapasztalatát biztosíthatják. Az alapvetően elméleti igényű, ám az empirikus kutatás számára is számos kérdést megnyitó tanulmány a hagyományos tanulási környezet sajátos ellenálló képességének okait keresi, és igyekszik rámutatni a lehetséges beavatkozási pontokra.

Published: November 2022

O racismo da sociedade brasileira se apresenta de várias maneiras, uma delas é através do epistemicídio que insiste em silenciar e invisibilizar a contribuição tecno científica de povos afro-brasileiros. Esse saber continua ausente nas licenciaturas das ciências naturais que tem currículos ancorados em princípios eurocêntricos. Com a intenção de ofertar uma educação antirracista é que propomos uma oficina colaborativa com licenciandos do PIBID-Ciências que contemple “saberes outros”. Destacamos neste trabalho, o terceiro encontro por evidenciar a produção ativa da ignorância e o epistemicídio como estratégia da formação docente. Com aporte da Teoria Ator-Rede evidenciamos a afetação gerada entre os licenciandos e o quanto a negação da intelectualidade de corpos negros pode ter consequências devastadoras para a democratização do ensino.

Published: November 2022

Este artigo objetiva caracterizar a representação imagética de corpos negros em quatro coleções de livros didáticos de Ciências da Natureza e suas Tecnologias, aprovadas no PNLD-EM/2021. Os critérios para aprovação das coleções têm íntima relação com a lei 10.639/03, que representa um compromisso com a educação das relações étnico-raciais e o combate ao racismo. A metodologia da pesquisa teve caráter quanti-qualitativo para analisar as coleções segundo o número total e o tipo de imagens em categorias analíticas. Os resultados indicam a ínfima presença de imagens de corpos negros, representando 12% das imagens totais. Os impactos que esta sub-representação negra causará na população estudantil precisam ser creditados à omissão dessas coleções, pois não mostram comprometimento com o combate do racismo.

SOCIAL PROTECTION EXPENDITURES IN CENTRAL AND EASTERN EUROPEAN COUNTRIES: DOES GOVERNMENT DEBT MATTER?
Authors: Tashevska Biljana , Makreshanska Mladenovska Suzana , Trpkova-Nestorovska Marija
Published: November 2022

The paper examines the potential effect of government debt on the social protection expenditure level in Central and Eastern European countries. More specifically, we examined whether governments reduce social protection spending when the fiscal stance worsens and when debt rises, in order to avoid fiscal unsustainability. This is a topical issue, given the population ageing and the level of indebtedness in some countries. Many studies have explored the economic and fiscal effects of rising social protection expenditures, but a few studies have examined the reaction of this specific expenditure category to rising debt levels. In addition, we examine the response of social protection expenditures to the changes in the level of economic activity, unemployment, inequality and population ageing. We found a small, but statistically significant positive effect of government debt to social protection expenditure, in line with the argument of coexistence of rising debt levels and rising social expenditure during recession and confirming their resilience to spending cuts. It could also be argued that these countries are not excessively indebted, and this could potentially contribute to the smaller response to increased debt levels. The results also indicate a negative impact of general government balance, implying that improved fiscal balance leads to lower social spending. The counter-cyclical nature of social protection expenditures is confirmed with the negative impact of GDP growth and the positive impact of unemployment. The negative effect of the Gini coefficient indicates that countries with lower inequality levels dedicate more resources to social protection. We didn’t find a strong influence from the dependency ratio.

Authors: Mojsovska Silvana , Bjelic Predrag
Published: November 2022

This article addresses non-tariff measures applied in CEFTA 2006, analysed specifically from the perspective of two Parties – North Macedonia and Serbia. It provides insight into the business community’s views in each country with regard to the non-tariff measures noted in their trade within CEFTA, as well as comparison of the Macedonian and Serbian case of imposing, addressing and overcoming the non-tariff measures. The article derives on the findings of the empirical research conducted in parallel in both countries in June-August 2021 within the framework of the EU Funded GIZ Project: Support to the Regional Economic Integration. It also reflects relevant legislation, such as CEFTA 2006 Protocols. In terms of content, the article includes overview of the trade within CEFTA 2006 and focuses on the non-tariff measures relevant to North Macedonia and Serbia, in particular - sanitary and phytosanitary measures; technical barriers to trade; price control measures and trade facilitation measures, such as formalities connected with import, export and transit, along with the procedures of release and clearance of the goods. The analysis of the empirical information indicates that sanitary and phytosanitary measures and trade facilitation have been reported as most common problems by both parties, despite the CEFTA Protocols regulating some of the issues. The article’s conclusions mirror the findings of the research and provide recommendations about possibilities for overcoming the non-tariff measures in CEFTA 2006.
SAİD HALİM PAŞA’DA HUKUK VE TOPLUM İLİŞKİSİ
Authors: KADIOĞLU Ahmet Selim
Published: November 2022

Hukukun temelde toplumsal bir olgu olduğu, toplum dikkate alınmadan hukukun mahiyetine dair yetkin bir anlama çabasının yürütülemeyeceği açıktır. Bu anlama çabası ise iki koldan yürütülmek durumundadır. Birincisi, yerelliklere inmeden mutlak olarak hukuk dediğimiz olgunun yine aynı ölçekte toplum kavramıyla ilişkisinin incelenmesidir. İkincisi, ayrı ayrı toplumlarda halihazırda yaşayan ve tevarüs edilen hukuk ile ait olduğu toplum arasındaki ilişkinin incelenmesidir. Bu noktadaysa toplumsal aktörlerin incelenmesi ayrı bir önem taşımaktadır. Bu çalışmamızda Osmanlı’nın son yüzyılında başlayıp Cumhuriyet’le devam eden siyasal, sosyal ve hukuksal değişim sürecinde etkin aktörlerden biri olan Said Halim Paşa’nın hukuk ve toplum ilişkisi çerçevesinde görüşleri incelenmektedir. Said Halim bir yandan, hem II. Abdülhamid devrinde hem de İttihat ve Terakki devrinde Sadrazamlık ve Parti Genel Başkanlığına kadar uzanan yüksek bürokratik ve siyasi görevleriyle etkin bir uygulamacı iken diğer yandan da fikri mesaisini aktif biçimde sürdürmüştür. Said Halim, düşünsel çalışmalarının odağına devletin ve milletin çöküntü ve çözülmeden nasıl kurtarılabileceği sorununu almıştır. Uygulayıcı ve teorisyen kimliğiyle faal bir aktör olarak toplumsal sorunlara eğilen, bu kapsamda hukuka ve hukuk-toplum ilişkilerine de değinen Said Halim, konunun Türkiye eksenli ele alınışlarında fikirleri dikkate alınması gereken önemli düşünürlerden biridir.

The rapid expansion of internet usage and related services like social media and blogs has increased people's level of expressiveness in day-to-day life. Social media platforms like Twitter and Facebook facilitate people to interact and exchange opinions about people, products, and services. As a result, a vast amount of data is available online in the form of views, tweets, messages, audio, and videos. An interface is needed to collect knowledge and insights from the various tweets, ideas, and comments. Thus we have proposed the Twitter API-based Interface, able to perform Hashtag searches and extract tweets from Twitter along with the ample number of fields related to the Twitter object. Using the interface, the 55 properties of each tweet are collected and used for further investigations. The python-based library called Tweepy is used to interact with the Twitter API. Due to the availability of real-worlddata, various issues related to text analysis can be addressed. The problems such as Sentiment Analysis, Opinion Mining, Implicit and Explicit detection, genuineness of views, and Opinion Spam detection can be addressed using the dataset availability.

A study was carried out in order to compare the detection of Trichomonas gallinae by examination of smears of throat swab and culture of protozoa collected from both pigeon and chicken. In the present study, five culture media viz. Modified Diamond’s Media, Nutrient broth, Medium 199, Minimum Essential Medium (MEM) and Roswell Park Memorial Institute-1640 (RPMI-1640) were used for culture of T. gallinae. Microscopic examination of wet mount/ Giemsa stained smear and culture of the T. gallinae revealed the latter method to be superior to wet mount preparation or staining methods.

Abstract
Caudal regression syndrome is a rare anomaly that is characterised by impaired development of the lower half of the body. This includes absent or abnormal development of lumbar and sacrococcygeal segments. Other associations of this disease include abnormalities of genitourinary tract, gastrointestinal tract, and cardiopulmonary system. The exact aetiology is unknown and is believed to be multifactorial but maternal diabetes is significantly linked to this rare disorder. We report the case of a new-born baby boy with caudal regression syndrome, hyperbilirubinaemia and patent ductus arteriosus.

The European Green Deal (EGD) signing has kicked off a “long-haul route” that European companies must take to protect the environment and mitigate climate change. To what extent the Romanian companies have started, we can only find out if they are willing to provide information in the annual reports. The elements presented in this regard through integrated reporting and the informative role will influence the decision-making regarding the future of the economic entity regarding the operational activity, financing needs, or investment possibilities. All this considers risks and opportunities and the geographical space in which the economic entity operates. In this article, we aim to identify the information provided by companies on the actions taken to achieve the purpose of the European Green Deal. In this regard, there were analyzed annual reports elaborated by the companies whose securities are traded on the Bucharest Stock Exchange and carry out their activity in the fields with impact on the environment and climate, respectively, the extractive industry and the energy-producing industry. We extracted financial and non-financial information from the annual reports regarding the companies’ actions to protect the environment, maintain sustainability, reduce pollution, and develop an ecological lifestyle. As a result of the research, we identified the differences and similarities in presenting information in the annual financial reporting before (2017-2018 period) and after the end of the European Green Deal (2019-2020). We consider that the analysis of the information – regarding the protection of the environment, the climatic neutrality, the ecological life profile, the economic growth – disclosed in the financial statements of the companies subjected to the case study in the light of the EGD represents the authors’ contribution.
