HRM Analysis of Spermathecal Contents to Determine the Origin of Drones that Inseminated Honey Bee Queens
Authors: Kahya Yasin
Published: October 2020

Europe, Africa and the Middle East have several original subspecies of the western honey bee (Apis mellifera L.), each with distinctive characteristics. These subspecies are the product of natural selection in their native range. Nevertheless, anthropogenic impacts such as migratory beekeeping and use of non-native queens result in an admixture of these subspecies and their ecotypes. I aimed to develop a SNP-based method to detect whether queen honey bees were mated with drones from foreign subspecies. For this purpose, Caucasian and Italian queens and drones were reared. Each queen was instrumentally inseminated with mixed semen collected from Caucasian (4 μl) and Italian drones (4 μl). The spermathecae of queens were dissected out after the onset of oviposition. The DNA was extracted from each spermatheca and from the thoraces of Caucasian and Italian drones. Seven regions on mtDNA that were isolated from drones were sequenced to determine the SNPs, enabling the discrimination of Caucasian sperm from Italian in spermathecal contents. Based on one SNP (11606. bp, T/C) residing on the Cytb gene, a specific primer was designed to be used in High Resolution Melting (HRM) analysis. HRM analysis indicated that heteroduplex peak profiles were present in all spermathecal contents of instrumentally inseminated queens. The results provide proof of the concept that the presence of likely non-native mitochondrial lineages can be detected by HRM analysis based on the SNP genotyping of spermathecal contents.

Published: October 2020

To improve the sensitive and reliability of condition monitoring in gas insulated switchgear (GIS), discharge perception system applied to GIS insulators protrusion discharge based on single ultraviolet photon is built. Step method is used to inspire the discharges of different severity, based on which, the regression relationship of ultraviolet (UV) signal and electrical signal are studied, and the perception mechanism of UV signal in different severity of discharges is analyzed. The study indicates that, the development of protrusion discharge in GIS can be divided into four stages, and there is no positive correlation between the number of ultraviolet photons caused by discharge radiation and insulation deterioration level, but related to the diffusion, migration and recombination of charged particles, then UV optical method for quantitative monitoring of discharge in each stage is provided, which provide a new method for quantitative measurement of GIS insulator discharge.
Environmental variables and macrophytes of lakes of the Chitwan National Park, Central Nepal
Authors: Bhusal Ashika , Devkota Anjana
Published: October 2020

Wetlands are areas where water is the primary factor controlling the environment, associated plant and animal life. The present study has been conducted to investigate the environmental variables of water and to make a quantitative analysis of aquatic macrophytes. Five lakes, i.e. Tamor, Beeshazar, Kingfisher, Athaieshazar and Chepang of the Chitwan National Park were studied during the post-monsoon season. Four different sites were studied for each lake. 12 replica of water samples were collected from each site of the lakes and environmental variables of water i.e. pH, temperature, dissolved oxygen, total alkalinity, conductivity, total hardness, nitrate, inorganic phosphorus, total solid matter and free CO2 were analyzed. Macrophyte floras were collected during field sampling with the help of a 1m×1m light wooden quadrat and herbaria were prepared following the standard technique. Altogether 10 quadrats (five paired quadrats) were plotted in each site of the study area. Data obtained from water analysis and macrophytes were analyzed by SPSS statistics 20 and CANACO version 4.5. Higher values of nitrate and inorganic phosphorus were found in Beeshazar Lake and Tamor Lake, i.e. 4.41 ±0.52 mg dm–3 and 2.93 ±0.29 mg dm–3, respectively. In most of the lakes, macrophyte species, mostly Eichhornia crassipes was found to be dominant in terms of the importance value index (IVI), whereas in Tamor Lake, Spirodela polyrhiza was dominant. All the studied lakes were in the hypereutrophic category on the basis of nitrate and phosphorus concentration. Runoff of polluted water with agricultural fertilizers, pesticides and untreated industrial discharge as well as domestic wastes from the Khageri canal and excessive growth of invasive macrophytes are major threats to the studied lakes. The luxuriant growth of invasive macrophytes like Eichhornia crassipes also revealed the productive nature of the lakes and they can be taken as ecological indicators of organic pollution.
Heat reserves of lakes of Belarus
Authors: Kirvel Pavel
Published: October 2020

The article concerns changes in the heat reserves of the lakes of Belarus in connection with the emerging trends of global warming. When calculating the heat reserves of lakes the method proposed by the Hydromet service was adopted. This technique allows the heat reserves of lakes to be determined with greater accuracy for subsequent comparison and discovery of spatio-temporal connections. The heat reserves were calculated for five lakes whose temperature regime has been constantly monitored. A quantitative assessment of changes in heat reserves for the period of instrumental observations was obtained. It was found that the average range of fluctuations in the gradients of heat reserves of lakes for the Belarusian Lake District ranges from 2.71×1015 J in May to 54.56×1015 J in August; for Belarusian Polesie – from 2.78 to 4.17×1015 J, respectively. The cyclicity of fluctuations in the heat reserves of lakes of Belarus was revealed and found to be short-period (3-5 years) and long-period (10-11 years) cycles.

Published: October 2020

The intensive development of renewable energy, especially solar power and wind power plants, poses risks of disrupting the balance reliability of the grid. There is the need to develop electricity storage system area, first of all, due to the global tendency to increase the demand for electricity and the number of electricity generation from renewable sources. The issue of guaranteeing electricity supply to the consumer operating in the autonomous renewable source – energy storage device – consumer system is the main criterion when selecting the installed capacity of the generator on the basis of renewable sources and energy storage device capacity. Also, the application does not allow reducing voltage fluctuations in the renewable sources – the consumer system.

Published: October 2020

The authors perform a comparative analysis of the efficiency of two types of low-power wind energy conversion systems with horizontal and vertical axis in the meteorological conditions of Latvia. The analysis is based on long-term wind speed measurements over the period of two years conducted by a network of 22 observation stations at the height of 10 m above the ground. The study shows that in the conditions of Latvia wind turbines with a horizontal axis are expected to work with greater efficiency than similar installations with a vertical axis. The paper presents the models of the spatial distribution of average wind speed, Weibull wind speed frequency distribution parameters and the values of the expected operational efficiency for small wind turbine generators. The modelling results are presented in the form of colour contour maps. Overall, the results of the study can serve as a tool for forecasting annual energy production and for estimating the feasibility of commercial use of wind energy at the height of 10 m in the territory of Latvia.
Local food policies – their constraints and drivers: Insights from Portuguese Urban Agriculture initiatives
Authors: Delgado Cecília
Published: October 2020

Two interconnected questions are addressed in this paper: (i) why urban agriculture (UA) and food-related initiatives take usually years to materialise in Portugal; and (ii) why resilient initiatives do not scale up and shift from practices to local food policies. We argue that existing initiatives are viewed as single events and therefore garner quite limited long-term political commitment and support. Based on interviews with food champions and a literature review, four Portuguese UA initiatives are analysed and these highlight the constraints that hinder their scaling-up. We conclude that drivers to lead to scaling-up are a combination of factors, with an enabling environment the most relevant one. On the other hand, constraints are related to limited democratic governance and poor policies, insufficient funding and weak participatory processes. Such findings are quite in line with existing literature. The limited integration of Portugal within the international UA and food debates might partially explain why UA is still struggling to find its proper place in Portuguese cities and their peripheries. Raising awareness among decision makers is critical to scaling-up UA initiatives and turning them an integral component of local food systems. A national observatory able to gather relevant data and produce knowledge, assess and monitor on-going initiatives may be the key step to gather different stakeholders together, that can then better advocate and then lead to higher political support, not only in Portugal but in any country where UA and food issues are emerging.
Consistency of the presentation of forests on topographic maps
Authors: Cebrykow Paweł , Petrzak Piotr
Published: October 2020

This article analyses the accuracy of the presentation of forests on Polish topographic maps. Four test polygons were selected, differing in forest coverage and spatial distribution of forest areas in order to improve the objectivity of the study. All the polygons were located in Roztocze. Four maps were tested: System 1965 (1:50 000), GUGIK80 (1:100 000), PUWG92 (1:10 000), and VMap L2 (1:50 000). The forest areas from the maps and aerial photographs were vectorised; then the photographs were converted into an orthophotomap that constituted the reference material. All materials were coherent in terms of content validity. After vectorising the range of the forests, sampling was conducted within the hexagonal fields. A comparison of the obtained values provided the basis for maps that presented the errors. The analysis permitted several conclusions to be drawn, generally stating that the credibility of maps within the scope of presenting forest areas depends on the scale and purpose of the map, and that any analyses based on these maps should assume that the results should have higher tolerance levels.
Integrating the non-EU immigrants into the EU labour market. An econometric analysis of some of the specific factors
Authors: Nicolescu Andreea Florentina , Drăgan Gabriela
Published: October 2020

The article explores the impact of some specific barriers to the integration of non-EU immigrants on the European Union labour market, measuring the influence of age, level of education and investments on the employment rate of non-EU immigrants. The study is based on a mixed approach, combining a statistically descriptive analysis of the 2008-2018 European labour market trends (in terms of the non-EU immigrants’ employment rate) with an econometric evaluation, aiming to measure the influence of investments (in terms of % of Gross fixed capital formation in Gross Domestic Product), age of asylum seekers (in terms of % of total asylum seekers) and level of education of non – EU immigrants (in terms of % of total non – EU immigrants). The analysis highlights the fact that the highest impact of non-EU immigrants on the employment rate is found in the case of non-EU immigrants with age between 18-34 and 35-64 years and with a tertiary level of education. For the other categories of non-EU immigrants, with ages outside the aforementioned range and with a lower level of education, the challenges are even much greater, which indicates the importance of specific educational integration policies, focusing mainly on continuous education and training.
Multi-level Governance and Energy Specifics of the V4 Countries within the Context of European Integration
Authors: Bauerová Helena , Vošta Milan
Published: October 2020

The topic of energy is still one of the most sensitive policy areas. The aim of this article is to examine the multi-level governance and energy specifics of the V4 countries within the context of European integration by analyzing selected the specifics of the energy mix of the V4 group countries. This will be carried out within the context of applying the theory of multilevel governance. The paper shows how energy policy is formed at state, and/or non-state level, as well as how these levels are influenced by the EU. The article also looks at the efforts taken to shape a common energy policy. A closer examination of the individual countries‘ levels lies outside the scope of this article. Therefore, the framework was chosen with regard to the particular features within the context of the functioning of the V4 group of countries. Using multi-level governance as a theoretical concept, the authors considered the limits arising from the determination of levels and the subjects of the survey, as well as having distinguished three levels of analysis. The first is the supranational level. This is represented by the EU. The second level is represented by the V4 states. The third level is the state as the actor that formulates energy policy, sets the energy mix and subsequently manifests itself in relation to the EU and the V4 group. Energy policy is significantly influenced by states, especially in the area of energy security of fuel supplies, or that of setting the energy mix. With the gradual communitarization of energy policy, the EU’s influence is growing and it is debatable how the evaluation of existing strategic plans, presented by individual states, will be done. The role of the V4 group is the weakest of the three levels of analysis which were examined. However, its increasing influence can be predicted mainly in the case of coal depletion and the perception of nuclear energy as a renewable source.

Authors: Majder Klaudia , Więch Paweł , Wojniak Agnieszka , Bazaliński Dariusz
Published: October 2020

Introduction. Medical history and physical examination are basic elements allowing nurses to assess patients’ health. The ability to auscultate the chest in combination with anatomical and physiological knowledge constitute a quick and reliable method of differentiation and diagnosis of many diseases.

Aim. The aim of the study was to assess knowledge and skills in the field of chest auscultation among nursing staff .

Material and method. A prospective, pilot observational study was conducted on a group of 51 nurses. The level of knowledge and skills in the field of chest auscultation and independence in undertaking this activity in professional work were assessed. The knowledge test developed by the author, survey questionnaire and SimScope 360-3400 trainer were used. P<0.05 value was considered statistically significant.

Results. Lack of chest auscultation skills was observed in 10% of the respondents, although none of them revealed lack of knowledge in this respect (p<0.001). Higher level of knowledge correlated with higher level of skills of the respondents, while a lower level of knowledge conditioned a lower level of skills (p=0.049). In the respondents’ opinion, auscultation of the lungs and heart are activities performed only by a doctor.

Conclusions. Despite a moderate level of knowledge and skills in the field of chest auscultation, nursing staff do not use physical examination techniques in their daily work.

Published: October 2020

Introduction. The history of recommendations by the Polish Federation for Education in Diabetology dates back to 2006, when guidelines for nurses/midwifes working with diabetic patients were first drawn up. However, the development of nurses and midwifes? competences requires stronger actions that foster a transition from experience-based towards evidence-based practice.

Aim. The aim of this publication is to present a set of procedures describing nursing interventions in diabetes care, including currently available scientific evidence and clinical experience of specialists involved in the care of diabetic patients.

Material and methods. The study involved a literature review of selected areas of nursing practice in diabetes care. When compiling the material, the priority was to use data from (in order of significance): randomized controlled clinical trials and their meta-analyses, observational studies and other studies with an adequate scientific status.

Results. This joint study yielded 11 procedures describing selected aspects of nursing interventions in diabetic patients. Each of the procedures details key recommendations on diabetes care, arranged in accordance of the significance ascribed to the scientific evidence analyzed.

Conclusions. The 2020 PFED guidelines on nursing and midwifery diabetes care are the effect of the evaluation of the previous versions and comprise a considerably more extensive, comprehensive and evidence-based set of practices. The major asset of these guidelines is their interdisciplinarity, reflected in the fact that the final version of the publication was approved by consultants in numerous nursing fields, a consultant in diabetology, and the President of the Polish Federation for Education in Diabetology, who all represent the medical community. The authors experience gained during work on international recommendations (New Insulin Delivery Recommendations) played an important role when formulating the present guidelines.

Authors: Showard Ansam F. , Aswood Murtadha SH.
Published: October 2020

Uranium concentrations of human blood and soil samples have been studied at different ages and occupations in Babylon, Iraq. The technique of nuclear track detectors CR 39 with nuclear fission track analysis has been used to determine the uranium concentrations in this study. Results have shown that the concentrations of uranium ranged from 0.56 ± 0.06 to 1.24 ± 0.29 ppb with an average of 0.83 ± 0.18 ppb in blood samples. On the other hand, the concentrations of uranium in soil samples ranged from 0.93 ± 0.20 to 2.59 ± 0.15 ppm with an average of 1.72 ± 0.19 ppm. Moreover, the highest averages of concentration have been found in the city center of Babylon, reaching 1.09 ± 0.22 ppb and 2.10 ± 0.23 ppm in blood and soil samples, respectively. The results have further proved that gender and occupations have an effect in increasing the concentrations of uranium. In addition, the concentrations in blood samples are generally lower than the concentration in soil samples.

Authors: Lewenstein Krzysztof , Ślubowska Elżbieta , Hawłas Hubert Jan
Published: October 2020

Alcoholism is one of the most widely occurring addiction in the world. In this paper, we proposed the method of addiction detection based on polysomnography. We have got the sleep records which were described by numerical parameters calculated from standard processed records of polysomnography signals. The database used in the experiments consisted of 172 examinations: 50% of healthy and alcohol-addicted patients, and 50% males and females, with normal-like age distribution. For the diagnosis, we have used the decision system built on an artificial neural network.

In our investigations, we have optimised the input set of parameters and the network structure. To verify the correctness of the diagnosis we have used the “leave one out” validation method.

Finally, we have obtained over 97% correctness of alcohol addiction diagnoses for different, optimised sets of data for men and women. we got the 8 parameters described men and 11 for women where only 5 has been common. What must be underlined such a positive result was obtained by dividing the data base. For the whole base, we have got only about 89% correct diagnoses.
Neurofeedback – A Method Which Trains the Brain to Obtain Changes in Behaviour
Authors: Pop-Jordanova Nada , Pop-Jordanov Jordan
Published: October 2020

EEG can determine changes in brain activity that might be useful in diagnosing different brain disorders as well as some mental states. Many advantages of this record have been the reason for resurrect the EEG in current clinical practice and research. More sophisticated form, the Q-EEG comprises a procedure that processes the recorded EEG activity from a multi-electrode recording using a computer, where data is processed with various algorithms, such as the Fourier or Wavelet analysis. Q-EEG data are important as a marker for many psychophysiological disorders.

Neurofeedback (NF) is a form of behavioural training aimed at developing skills for self-regulation of brain activity. It is a treatment method for altering brain functioning by the use of signals provided to a patient that reflect the moment-to-moment changes in the patient’s electroencephalogram.

This article summarizes some of our large experience with neurofeedback training in different groups of disorders in children and adolescents. Positive outcome is promising for more expansive use of this non-pharmacological, cost-benefit methodology in paediatric and general population.

Authors: Basic-Jukic Nikolina , Furic-Cunko Vesna , Juric Ivana
Published: October 2020

Aim: Data on the use of novel anticoagulant drugs (NOACc) in renal transplant recipients is scarce. The aim of our study was to investigate the safety and efficacy of NOACs in renal transplant recipients.

Materials and Methods: In a single-centre retrospective cohort study we assessed adverse reactions, thromboembolic events, and interactions of calcineurin inhibitors in patients treated with NOACs.

Results: Twenty-three renal transplant recipients were treated with NOACs (70% male), mean age of 65.8 ± 1.8 years. Fourteen (61%) patients were treated with rivaroxaban, apixaban was given to 8 (35%) of our patients, and dabigatran to one patient (4%). The main indications for NOAC therapy was atrial fibrillation in 61% and deep venous thrombosis in 23% of patients. Bleeding occurred in 2 patients (1 treated with rivaroxaban and 1 with dabigatran). None of our patients developed thrombosis while treated with NOAC. During the median follow-up of 24 months graft function, as well as hematological parameters, remained stable in patients that were treated with rivaroxaban and apixaban, while dabigatran was ceased after a month of therapy due to a bleeding event.

Conclusion: Our results show that both rivaroxaban and apixaban are safe and efficient oral anticoagulant drugs in renal transplant patients. Additional studies are needed to prove these results.

Published: October 2020

Introduction: Seasonal influenza, although often presented as a mild, self-limiting disease, is frequently accompanied by complications that lead to the development of a severe clinical presentation and a fatal outcome. The most common are respiratory complications, with secondary bacterial pneumonia being the leading cause.

Aim: The aim of this study is to determine the impact of pneumonia on the severity of the clinical presentation and outcome in patients with seasonal influenza.

Materials and Methods: This research is comparatively group-based and has been conducted at the University Clinic for Infectious Diseases and Febrile Conditions during a three-year period. The analysis consists of 122 adult patients with clinically and laboratory-confirmed influenza. Based on the severity of the clinical picture, the patients are divided into two groups, severe (n=87) and mild (n=35) forms of the disease. The study included demographic, general data, clinical symptoms, and signs as well as complications.

Results: Of 122 patients with seasonal influenza, complications were registered among 108(88.52%), with a significantly more frequent emergence among the group with severe influenza 93.1% vs 77.14% (p=0.012). Pneumonia was the most common 98(80.33%) and had a significant effect on disease severity (p=0.002). Complications from the types of ABI 8(6.56%), ARDS 7(5.74%), sepsis 5(4.1%), DIC 4 (3.28%) and otitis 2(1.64%) were reported only in the group with severe influenza. Acute meningoencephalitis was registered among 5(4.1%), gastroenterocolitis among 3(2.46%), and hepatic damage among 14(11.47%) of patients.

Conclusion: Pneumonia as the most common complication among patients with seasonal influenza significantly impacts the clinical course and outcome of the illness.

Authors: Andonovski Alan , Andonovska Biljana , Trpeski Simon
Published: October 2020

Background: The surgical treatment of chronic patellar tendinopathy could be open or arthroscopic. A general agreement on the best surgical treatment option is still lacking.

Purpose: The aim of our study was to evaluate the clinical results after a minimally invasive arthroscopic treatment of chronic patellar tendinopathy including a resection of the lower patellar pole.

Methods: The study included 14 patients with a mean age of 26 years and chronic patellar tendinopathy refractory to non-operative treatment of more than 6 months. All patients underwent arthroscopic debridement of the adipose tissue of the Hoffa’s body posterior to the patellar tendon, debridement of abnormal patellar tendon and resection of the lower patellar pole. Preoperative and postoperative evaluation was undertaken using clinical examination, magnetic resonance imaging (MRI) and the Lysholm and Victorian Institute of Sport Assessment-Patella (VISA-P) scores. Return to sports and postoperative complications were also assessed. The mean follow-up was 12.2 ± 0.9 months.

Results: All 14 patients continued with sport activities, but only 12 of them (85.7%) achieved their presymptom sporting level. The median time to return to preinjury level of activity was 3.9 ± 0.8 months. Patients showed a major improvement in the mean Lysholm score from 51.1 ± 3.8 to 93.4 ± 4.2 (p=0.001) and in the mean VISA-P score from 42.1 ± 3.5 to 86.7 ± 8.4 (p=0.001) There were no postoperative complications.

Conclusion: We found that this arthroscopic technique gives reduced morbidity and satisfactory outcome resulting in significantly faster recovery and return to sports in patients with chronic patellar tendinopathy.
A History of Detection of Explosive Devices 1. (700-1950)
Authors: Horváth Tibor , Szatai József Zsolt
Published: October 2020

This study presents the history of explosive devices and that of their detection. With the invention of explosive devices and their subsequent use, the methods of warfare changed significantly. New procedures emerged that were already unthinkable to implement without the use of such tools. In parallel with the emergence of explosive devices with increasing destructive power, the need to deactivate them also came to the fore. Opposing parties made increasing efforts to detect, deactivate, and destroy explosive devices. After the completion of military operations, the detection of explosive devices did not lose its importance, and developed into an essential mission, since the areas had to be cleared of devices left over from the military actions and posing a murderous danger.

Authors: Pomohaci Marcel , Sopa Ioan Sabin
Published: October 2020

Emergency occupations and mostly firefighter job demands high level of expertise managing critical situations that require a strong psychological and physical preparation. The investigation started from the assumption that having a good physical preparation program we will be able to develop physical strength and agility so that we can improve time in intervention situation simulated in the firefighter specific event of carrying the intervention device and mount the moto-pomp. The sample of the study was formed by the Inspectorate for Emergency Situations from Sibiu firefighter team that was composed by 10 male athletes with age between 30± 3.5 years old with experience in this kind of competitions between 2 and 7 years. The intervention program with a specific firefighter program was presented, work load and exercises that were applied, proving that can improve time and physical development of our athletes. The results showed relatively good improvements in the performance time starting from an initial time of 30.66 seconds at the initial testing to come close at the final testing at a 24.51 seconds result that is very close to the national record 22.07 seconds, and also to the international record of 21.05 seconds. The results were than calculated for statistical significance with the t Student test, and found that between the initial and final test values is a statistically significant difference with a value of p = 0.00001. Conclusions of our research showed that firefighters need to be physically prepared to intervene in critical situations for search and rescue in any situations that appeared thus a strong physical program can contribute to their physical shape and skills.

Governance options of municipal actors for reurbanisation in medium-sized cities. An analysis by the example of Bamberg
Authors: Boeth Henning
Published: October 2020

This paper examines the governance options for reurbanisation in medium-sized cities by using the example of Bamberg. The key questions are: Which planning approaches are developed in the areas of action housing and urban development to shape reurbanisation? How do local actor constellations and relationships shape the governance options? The contribution follows on debates about local reurbanisation drivers and an understanding of planning in terms of governance. The results show that Bamberg aimed to develop a conversion area and has thus implemented planning instruments and political-administrative structures. However, the use of the conversion areas by non-municipal actors in addition with municipal actors that are strongly guided by monetary considerations prevents the conversion in the further course and severely limits the governance options. As a result, a departure from the goal of a planned reurbanisation can be seen. The paper concludes by discussing the context under which growth policies for reurbanisation are developed and implemented.
Evaluation of eHealth Deployment at Primary Care in the EU Member States by Usage of Selected MCDM Methods
Authors: Ardielli Eva
Published: October 2020

Information and Communication Technologies have become a revolutionary part of European healthcare in recent years. The European Commission considers eHealth as an important and appropriate tool that can contribute to cope with the challenges that are currently affecting the healthcare systems in Europe. The development of eHealth is therefore embedded in many EU strategies and is being evaluated on an ongoing basis. In the past, several studies have been carried out focusing on the evaluation of individual areas of eHealth - especially on the area of primary care secured by General Practitioners and Acute Hospitals. However, no synthesis of these works was made. This paper is focused on the proposing of an assessment for both mentioned areas of eHealth. The aim is to evaluate the eHealth deployment in the European Union Member States by the synthesis of Composite Indicators in existing studies into the evaluation model based on the application of Multiple-Criteria Decision-Making techniques. The evaluation is performed by the usage of TOPSIS, WSA, and MAPPAC method. The result of the research is the design of an evaluation framework for eHealth that enables the comparison of eHealth indicators in the international context and evaluation of eHealth deployment in European Union Member States in the form of a ranking. In this ranking, the Nordic countries are among the best-rated countries, while the worst-rated countries are in Eastern Europe.
Legal aspects of registration the time of cadastral data creation or modification
Authors: Reczyńska Joanna , Hanus Paweł
Published: October 2020

In Poland, the cadastre is the basic register which is the source of information on cadastral entities and their property. Therefore, it should constitute a reliable source of information in the scope of establishing the range of law, its nature, but also the subject of its ownership. However, it is necessary to be able to not only check the current information on the legal status and its scope, but also review past statuses or determine the rights that will influence real estate in the future. The cadastre and related rights are changing very dynamically over time, and each state has a very strict reference to the previous state. Therefore, in order to manage real estate in the most effective way, it is necessary to record temporal attributes of cadastre objects.

The main objective of this paper is to define the legal issues related to the possibility of registration at the time of creation or modification of object in the Polish cadastre. This paper includes analyses of both Polish legal regulations and European standards and norms. Moreover, the article presents the results of comparative analyses concerning the data model of cadastre and INSPIRE and Land Administration Domain Model (LADM) data models for the theme cadastral parcel in terms of temporal aspect.

The Titanic Series: Reflections on Cambridge University Press’s Edition of the Literary Works of Joseph Conrad
Authors: Watts Cedric
Published: October 2020

Cambridge University Press’s vast project to produce authoritative new editions of the literary works of Joseph Conrad is now well advanced; but the project is flawed. I maintain that this is the Titanic of editions: big, costly, important, and disastrous. I specify “the literary works”, because I am not concerned with the admirable volumes of Conrad’s letters.

The industrious Cambridge editors have done excellent work in correcting longstanding errors and in bringing to light much textual material which was previously lost. The edition is therefore indispensable. The editors have, however, deleted much house styling and correction: “successive layers of non-authorial intervention affecting wording and ‘accidentals’ – punctuation, spelling and word-division”. The result of the Cambridge editorial procedures is a Conradian prose which is often impoverished and is sometimes even ungrammatical and uncouth. In removing much punctuation, the editors have often removed logical clarity and rhetorical effectiveness.

In this essay, therefore, I use a sequence of comparisons to demonstrate the presence of a pattern of flaws. The sequences are taken from Notes on Life and Letters, ’Twixt Land and Sea / Tales, Last Essays, Lord Jim, and The Nigger of the “Narcissus”. I compare extracts from the Cambridge texts with extracts taken from other editions.

Studies over the past decade have shown that microplastics are widespread in marine environments, at sea level, on coastlines, and the seabed. Microplastic sources come from small particles used in the cosmetic industry and plastic industry base materials. Other microplastic sources emerge through the degradation of larger pieces of plastic in the environment due to physical and chemical processes, caused by light, heat, oxygen, water, and organisms. Microplastics tend to be digestible by marine organisms and potentially transferred to higher trophic organisms through the food chain, and thus toxic pollutants will potentially harm marine organisms and even humans through bioaccumulation and biomagnification. This research was conducted to determine the characteristics of microplastics that pollute marine fish consumption that is landed in Bali. Samples were gathered from traditional fishermen who landed their catch in Bali. Microplastic is identified in the digestive tract of fish. The samples of fish obtained by Decapterus spp (Selayang), Auxis Rochei (tongkol), Rastrelliger spp (kembung), and Sardinella lemuru (Lemuru). 39 fish out of the total identified 89 fish were found to be contaminated with 69 microplastics (fiber, fragments, film) and 1 mesoplastic (fragment). The size of the plastic found is between 0.32 to 22 mm. The abundance of microplastics in fish caught in Bali's waters is 0.78 (SD 1.15) particles/fish. The finding of microplastics in the digestive tract of fish caught by traditional fishermen in Bali is feared to have the potential to harm marine organisms and even humans through the process of bioaccumulation and biomagnification.
