Authors: Twala Mandla Alfred , Twala Boniswa Charlotte
Published: April 2022

This study investigated  the attitudes of the permanent residents  and the squatter-settlements regarding the existence of crime, and the socio-environmental problems experienced by the permanent residents of Greater Breyten Urban Community due to the existence of the squatters in their areas. This  growth of squatter settlements, informal settlements, slums along the formal settlement and or urban areas is a global phenomenon. The research design in this study involved a descriptive design which reveals potential relationships between variables. According to the study, the researcher was describing the attitude and impact of quarters on the social environment of the Greater Breyten area. Data was also analyzed using frequencies and percentages. The findings revealed that there are no significant differences between the attitudes of the permanent residents and those of the squatter-settlements regarding the existence of crime. Besides, the socio-environmental problems, the results indicated that the conditions of squatters are poor and unhealthy for human habitation. Considering the findings of the study, the researcher proposed that there be a multi-disciplinary approach to present and provide resources to address the problem of squatter-settlement.
Social Skills, Autonomy and Communication in Children with Autism
Authors: Sălceanu Claudia , Lăcătuș Lucia
Published: April 2022

The number of people with autism spectrum disorder is growing at an accelerated rate from year to year. Unlike 20 or 30 years ago, when few people in the general population had ever heard of autism, now you rarely meet a person who has not heard of this disorder and does not know anyone with a relative diagnosed with ASD. A sample of 30 children with ASD was assessed with Adaptive Behavior Assessment System II (ABAS II), a Screening of personal autonomy skills from PEDa (Cognitrom, Cluj-Napoca) and a Screening of social skills from PEDa (Cognitrom, Cluj-Napoca). Our main objectives were: (O1) Identifying the correlations between personal autonomy, social skills, and communication in children with autism spectrum disorders, and (O2) Identifying the differences between personal autonomy, social skills, and communication according to the sex of children with autism spectrum disorder. The hypotheses of our study are: (1) It is assumed that there is a correlation between social skills and communication in children with autism spectrum disorder; (2) It is assumed that there is a correlation between communication and personal autonomy in children with autism spectrum disorder; (3) It is assumed that there is a difference in personal autonomy depending on the sex of children with ASD; (4) It is assumed that there is a difference in social skills according to the sex of children with ASD; (5) It is assumed that there is a difference in the development of communication according to the sex of children with ASD. Results show the existence of a relationship between communication, social skills, and personal autonomy, and we also obtained differences based on gender in social skills. In terms of personal autonomy and communication, although some differences were obtained, they were not statistically significant. Results are discussed in the context of the importance of personalized interventions plans for children with ASD.

Chatbots as Cognitive, Educational, Advisory & Coaching Systems
Authors: Karyotaki Maria , Drigas Athanasios , Skianis Charalabos
Published: April 2022

Chatbots are software applications assimilating human communication with the aim to raise adherence and engagement between human-systems interaction. Text messaging-based conversational agents (CAs) make an interesting use of natural language processing and improve by learning, allowing coherent two-way communication with humans, either oral or written as well as real-time decision-making. Chatbots serve as means of learning and teaching, as virtual assistants and social companions. Machine learning algorithms embedded into Chatbots simulate human cognition, including cognitive learning, decision making and adaptation to the environment. Thus, the future of artificial intelligence in Chatbots lies in the development of a global, reliable and sustainable ecosystem of knowledge, skills and values by bringing together all interested stakeholders, such as scientists, consumers, businesses and the state. Such effective customized/personalized learning frameworks depend on sophisticated conversational flows based on user models, which cluster user preferences and attributes in combination with learning analytics to induce end users’ personal skills, knowledge mastery, learning ability as well as professional development.

Published: April 2022

The extent of e-commerce use by SMEs in developing countries such as Indonesia is still relatively low. This study seeks to identify and test the sustainability factors of e-commerce use by SMEs in a developing country. This study uses TOE theory which was expanded by including 12 predictors of sustainability of e-commerce adoption into four sub-domains: technology, organization, environment, and psychology. The contribution of this study is to explain the relevance of predictors of e-commerce adoption differs across two-time phases: at the early adoption phase and the later phase. In particular, in the early adoption phase, competitive pressure is a variable that affects the sustainability of e-commerce adoption. While at the later phase, perceived trust and competitor pressure are predictors that affect the sustainability of e-commerce adoption. Another interesting finding from this study is that SMEs utilize online sales brokers to increase their production and sales. This is done by SMEs, because they are aware of the limited resources that SMEs have.
The Adoption and Use of Digital Literacy among Selected Libraries in Tertiary Colleges in Tanzania
Authors: Patrick Bulugu Paskazia , Tweve Julius Tunsaje
Published: April 2022

This study chiefly aimed at assessing the adoption and use of digital literacy among libraries in selected tertiary colleges. Two tertiary college were selected as cases studies, namely, Tanzania Public Service College (TPSC) and Dar es Salaam Maritime Institute (DMI).The study aimed at examining the status of digital literacy adoption, determining the use of digital literacy on their day-to-day activities, and identifying challenges of digital literacy adoption and use among libraries in selected colleges. A sample of 98 library users were selected as respondents. Data was collected through questionnaire and face-to-face interview. Quantitative data was analyzed using Statistical Package for the Social Sciences, while content analysis was used for qualitative data. The findings show that majority of the respondents were aware of the adoption and use of Digital Literacy, but faced challenges such as technophobia, lack of enough and supported instructions on digital literacy, poor power supply to support internet, and insufficient digital literacy facilities. In fact, the majority of respondents had adopted and used digital literacy for less than a year. The use of digital literacy has a number of benefits such as easy and quick access of information, retrieval of library information in cataloguing and classification, as well as accessing different databases to acquire relevant data and information. The study recommends that the government and top management of institutions or colleges should make available more funds to support libraries in the adoption and use of digital literacy, allow librarians to take short courses to enhance adoption and use of digital literacy, purchase more digital literacy facilities, purchase a strong standby generator, and accommodate digital literacy programmes in college curricula.
Inflammatory myofibroblastic tumour in otorhinolaryngology
Authors: Zeinerová Lucie , Černý Michal , Laco Jan , Dědková Jana , Chrobok Viktor
Published: April 2022

Introduction: Inflammatory myofibroblastic tumour (IMT) is a rare tumour with borderline biological behaviour composed of fibroblasts and myofibroblasts and accompanied by non-neoplastic inflammatory cells. It occurs mostly in children and young adults. The disease is most commonly seen in abdominal soft tissues (omentum, mesentery, etc.), in the lungs and also has been reported in other parts of gastrointestinal tract and other organs. In the head and neck region IMT is not so common, it may occur in larynx, trachea or nasal sinuses. The primary therapeutic approach is a complete surgical excision. Radiation, chemotherapy or biological treatment modalities are used in aggressive, non-resectable, and recurrent tumours or in case of metastases. Aims: Through a case report on a small set of patients and up-to-date information from the literature, the authors want to share knowledge about the rare diagnosis of IMT in ENT, its possible clinical manifestations, differential diagnosis and appropriate treatment. The group of patients, the case report: The paper presents patients with IMT treated at the Department of Otorhinolaryngology and Head and Neck Surgery, University Hospital Hradec Kralove in the years 2013–2020. The case of a 11-year-old boy with progressive dyspnoea caused by polypoid tracheal tumour is discussed in more detail. The tumour was removed by external surgical approach with bronchoscopy assistance. Histological examination proved an IMT. Conclusion: IMT is a rare neoplasm which must be included in the differential diagnosis of tumours of the respiratory tract, especially in children and young adults. The treatment consists of complete surgical removal and regular follow-up due to the risk of local recurrence. Keywords: inflammatory myofibroblastic tumour – dyspnoea in a child – tracheal tumour

Published: April 2022

Background: Nasal obstruction is one of the most common symptoms in rhinology. In 2004, Stewart published a very simple instrument of nasal obstruction symptom evaluation (NOSE), which has already been adapted and validated in a number of languages. The aim of this study was to validate the Czech version of the questionnaire (NOSE-cz). Materials and Methods: Two-centre prospective instrument validation study. The psychometric properties (reliability, validity, sensitivity) of the Czech version were assessed in 72 patients undergoing (rhino) septoplasty and 39 asymptomatic controls. Results: Internal consistency (Cronbach’s alpha 0.796 and 0.691 before and after surgery, respectively) and test-retest reliability (Pearson’s test, 0.74; P <0.0001) were very good. The instrument showed excellent discrimination between groups (two sample t-test; P <0.0001) and sensitivity (standardised response mean 2.53). Conclusions: The Czech version of NOSE (NOSE-cz) demonstrated good to excellent psychometric properties and its use is recommended for daily clinical practice and research. Keywords: Quality of life – nasal obstruction – validation – NOSE scale – septoplasty
Knowledge, attitudes, and skills among primary health care workers in developing health promotion settings in a district of Sri Lanka
Authors: SABHAPATHİGE Ranga , DEERASİNGHE Dilrukshi
Published: April 2022

Healthy sitting is defined as a place or social context in which people engage in daily activities in which environmental, organizational, and personal factors interact to affect health and wellbeing. This study was conducted to determine the knowledge, attitudes, and skills of primary health care workers in establishing health promotion settings in the Kalutara district, Sri Lanka.
This was a cross-sectional descriptive study. A structured, pre-tested, and self-administered questionnaire was used to collect data from study participants. The data were analyzed by using statistical tests and Chi-square values. A majority (215, 70.0%) had 'poor' knowledge. The knowledge was significantly associated with educational level GCE A/L or higher (P±0.012) and ability to read English (P±0.021). Public health experience of PHMM less than 5years was significantly associated with knowledge (P±0.002). The level of attitudes was good (204, 69.4%). The level of knowledge was significantly associated with the level of attitudes (P ± 0.004). Only 25.1% (77) had adequate skills. The level of skills was significantly associated with the existence of health promotional settings in their fields (P ± 0.000). Availability of healthy settings in the fields of PHMM with the extent of field areas less than the mean (P ± 0.017) was significantly associated. The present study concluded that PHCW had 'poor' knowledge and skills in health promotional setting while their attitudes were found to be 'good'. Lack of time and inadequate training in the field of health promotion were identified as the commonest barriers.
Art of the Modern Age
Authors: Schaeffer Jean-Marie
Published: April 2022

This is a sweeping and provocative work of aesthetic theory: a trenchant critique of the philosophy of art as it developed from the eighteenth century to the early twentieth century, combined with a carefully reasoned plea for a new and more flexible approach to art.

Jean-Marie Schaeffer, one of France's leading aestheticians, explores the writings of Kant, Schlegel, Novalis, Hegel, Schopenhauer, Nietzsche, and Heidegger to show that these diverse thinkers shared a common approach to art, which he calls the "speculative theory." According to this theory, art offers a special kind of intuitive, quasi-mystical knowledge, radically different from the rational knowledge acquired by science. This view encouraged theorists to consider artistic geniuses the high-priests of humanity, creators of works that reveal the invisible essence of the world. Philosophers came to regard inexpressibility as the aim of art, refused to consider second-tier creations genuine art, and helped to create conditions in which the genius was expected to shock, puzzle, and mystify the public. Schaeffer shows that this speculative theory helped give birth to romanticism, modernism, and the avant-garde, and paved the way for an unfortunate divorce between art and enjoyment, between "high art" and popular art, and between artists and their public.

Rejecting the speculative approach, Schaeffer concludes by defending a more tolerant theory of art that gives pleasure its due, includes popular art, tolerates less successful works, and accounts for personal tastes.
Literature, in Theory
Authors: Wolfreys Julian
Published: April 2022

Jacques Derrida has argued about the difference between literature and theory that despite its institutional status, part of its 'institution' is the right of literature to say anything. Literature cannot be defined as such, and as soon as one seeks to produce a reading of the literary, complications arise.

Yet despite its institutional significance, 'theory' remains something many wish would go away; and which, for others, is still not read, is misread, and remains to be read. Like literature, it remains as an enigmatic identity, resistant to definition, but subject to misperceptions and open to general statements that are more or less inaccurate.

By examining how 'theory' and 'literature' are concepts and names which touch on one other in complex ways, Julian Wolfreys seeks to understand their intersections and differences. Examining a wide range of authors, from Dickens to Joyce, and engaging directly with a number of major theorists, Wolfreys takes the reader on a journey through the issues and ideas involved in reading literature, in theory.

Ideal for undergraduate students coming to philosophical ethics for the first time, this book utilizes popular film to introduce a central topic in the study of philosophy.
Gender and Genius
Authors: Battersby Christine
Published: April 2022

During the Middle Ages and the Renaissance, women were blamed for having too much passion, imagination, and sexual appetite. By the late eighteen century, however, these qualities had been valued and appropriate for male artists. As new and old concepts of woman and genius clashed, there evolved a rhetoric of sexual apartheid which today still affects our perceptions of cultural achievement.

The Aesthetics of Education
Authors: Lewis Tyson E.
Published: April 2022

This innovative book examines the aesthetic event of education. Extending beyond the pedagogy of art or art appreciation, Tyson E. Lewis takes a much broader view of aesthetics and argues that teaching and learning are themselves aesthetic performances. As Jacques Ranciere has recently argued, there is an inherent connection between aesthetics and politics, both of which disrupt conventional distributions of who can speak and think. Here, Lewis extends Ranciere’s general thesis to examine how there is not only an aesthetics of politics but also an aesthetics of education. In particular, Lewis’ analysis focuses on several questions: What are the possibilities and limitations of building analogies between teachers and artists, education and specific aesthetic forms? What is the relationship between democracy and aesthetic sensibilities? Lewis examines these questions by juxtaposing Ranciere’s work on universal teaching, democracy, and aesthetics with Paulo Freire’s work on critical pedagogy, freedom, and literacy. The result is an extension and problematization of Ranciere’s project as well as a new appreciation for the largely ignored aesthetic dimension of Freire’s pedagogy of the oppressed.
Wittgenstein’s Family Letters
Authors: Ware Ben , Burley Mikel , Gorlȳe Dinda L.
Published: April 2022

With a quality all their own, Wittgenstein’s Family Letters reveals a side of Ludwig Wittgenstein few would have known. The familiarity and intimacy of the letters offer new insights into the development of his relationships and ideas over the course of forty years.

In his usual frank, and sometimes brutally honest manner, he explains his decisions to lead a life in absolute agreement with what he considered right for him. In correspondence with his siblings we learn more about Ludwig’s refusal to be known as a ‘Wittgenstein’ during his time as a school teacher and his insistence to celebrate Christmas not with the family, but with friends. Using a different tone for each of his siblings, he creates distinct portraits of the siblings themselves. The open and simple tone to Hermine, a mother figure to Ludwig; the practical and sometimes joking tone to Paul; and, most strikingly, the loving and witty tone to Helene Salzer, the sibling closest to Ludwig and with whom he remained in contact until his death. The most intellectual and original of his sisters, Margaret, is seen primarily through her letters to Ludwig, as almost no letters to her are believed to have survived from him.

Translated into English for the first time, these personal letters not only illuminate Wittgenstein the philosopher, they bring us closer to Ludwig Wittgenstein the man.

Authors: Da Silva Wemerson Flávio , Gonçalves Rhandysson Barbosa , Da Silva Carla Suelânea , João dos Santos Leandro Diomério , De Oliveira George Pereira , Girão Osvaldo
Published: April 2022

A bacia hidrográfica do rio da Chata tem como principal característica um controle estrutural de sua drenagem que se reflete nas unidades geomorfológicas e na morfologia do canal principal. A drenagem segue a direção dos trends regionais SW-SE/NW-SE, assim como, o rio da Chata sofre uma inflexura que muda abruptamente a direção do canal fluvial condicionado pela falha de empurrão e a Zona de Cisalhamento (ZC) dextral. Posteriormente, o canal principal da bacia se encaixa sobre uma ZC sinistral seguindo de forma retilínea até a sua foz sobre o vale estrutural. Ao longo do percurso o canal vai se adaptando as estruturas geológicas subjacentes onde, por vezes, é comandado pela erosão diferencial, ora pela ação direta das falhas e Zonas de Cisalhamento.
Perceptions of the professionalization of dental technology
Authors:   , Skea Denise Angela
Published: April 2022

This study investigates the perceptions of dentists, dental technicians and dental patients with regard to the professionalization of dental technology as it is currently constituted in South Africa. The origin of dental technology worldwide lies in a trade and has historically been performed by craftsmen under the instruction of dentists. In South Africa during the early 1900s dental technology was practised in much the same way but the need for formalization of this field had been recognised. By 1945 dental technology was regulated by the Dental Mechanicians Board, which enabled only registered technicians to practise dental technology within South Africa. This field continues to be practised similarly at present. In order to establish the professional development of dental technology it is necessary to consider this field within a framework of desired professional attributes. This framework is provided by Greenwood (1957), who defines a profession by the following five attributes: systematic theory, professional authority, community sanction, ethical codes and a professional culture. Owing to the varied implementation and regulation of dental technology worldwide, little research into the professionalization of this field has been conducted to date. For the purpose of this study, dentists, dental technicians and dental patients in KwaZulu-Natal were interviewed in semi-structured interviews. The main themes emerging from this study were identified and considered with reference to the framework within which this study has been positioned. This study concludes that dental technology, as it is currently constituted in South Africa is perceived to be a profession by dentists, dental technicians and dental patients. .The term profession, however, is poorly understood by all three sample groups. Despite being considered a profession, dental technology is not considered to encompass all the attributes of a profession. Dental technology is therefore identified as a developing profession that positions this field somewhere along the professionalization continuum between a profession and a business.
Assessment of bone mineral density in children with bone cysts
Authors: Hotim O. A. , Anosov V. S.
Published: April 2022

Objective. To assess an incidence rate of reduced bone mineral density (BMD) in children diagnosed with dystrophic bone cysts.

Materials and methods. We examined 2 groups of patients: 25 children diagnosed with dystrophic bone cysts (experimental group) and 42 children diagnosed with idiopathic scoliosis (control group). The methods were: dual X-ray absorptiometry (roentgen densitometry), computer tomography; the comparative assessment of the results was performed.

Results. It has been found that only in 36 % of the patients with bone cysts (n = 9), the BDM value was within the age norm, 36 % revealed osteopenia, 28 % – osteoporosis. Among the patients diagnosed with idiopathic scoliosis, changes in BMD were found only in 21.5 % (n = 9) of the patients (in 14.3 % of the cases — osteopenia, in 7.2 % – osteoporosis).

Conclusion. In addition to appropriate surgical treatment, it is necessary to measure BMD in children with dystrophic bone cysts.

Authors: Brankovskaya E. Yu.
Published: April 2022

Objective. To determine the features of the course and outcomes of macrofocal myocardial infarction (MI) complicated by ischemic acute renal failure.

Materials and methods. The study included 173 patients with acute macrofocal MI. The patients were stratified into two study groups based on the functional state of the kidneys at the time of their admission to hospital: 111 patients with MI and ischemic acute renal failure (ARF) (main group) and 62 patients with MI without ARF (comparison group).

Results. The patients with MI and ischemic ARF required longer inotropic and/or vasopressor support, more frequent use of intra-aortic balloon counterpulsation, the course of the disease in them was more often complicated by the development of prognostically unfavorable arrhythmias. The patients with MI and ARF compared to the patients without ARF revealed longer mean group time intervals from the onset of pain syndrome to the primary medical contact, a higher number of cases of adverse outcomes within 12 months from the onset of the disease.

Conclusion. Patients with macrofocal MI and ischemic ARF are characterized by a more severe course of the MI acute phase, as well as a more frequent development of adverse outcomes within 12 months from the onset of the disease.
Cell and tissue reactions in response to experimental implantation of modified artificial vascular prostheses
Authors: Lyzikov A. A. , Nadyrov E A. , Doroshko Y. Y.
Published: April 2022

Objective. To perform histological evaluation of cell and tissue reactions in response to experimental implantation of various variants of antibacterial modifications of artificial vascular prostheses.

Materials and methods. The study of the cell and tissue reactions was carried out on 45 laboratory white rats. Industrially produced samples of textile woven vascular prostheses modified by two types of developed coatings based on a polyvinyl-chitosan complex with the addition of biologically active substances and the antibiotic Vancomycin 1 % were studied. In accordance with the design of the study, the animals were removed from the experiment on the 5th, 14th day and 20th week of the postoperative period by means of decapitation. Samples were taken for histological examination.

Results. The study of the cellular composition of tissues along the periphery of the vascular prostheses has showed that the animals of the experimental groups had less pronounced inflammatory reactions compared with the control one on the 5th day of observation. The largest number of cells forming connective tissue fibers was in the samples of the second experimental group (p < 0.05). During the intermediate followup periods (day 14), the inflammatory reaction continued to decrease in the experimental samples and a high rate of formation and maturation of granulation tissue was observed (p < 0.05). The inflammatory productive reaction decreased significantly (p < 0.05) in the samples of the second experimental group compared to the first experimental group. During the late follow-up period (20 weeks), the experimental groups were significantly characterized (p < 0.05) by less severe chronic inflammation reactions and a higher degree of maturation and transformation of granulation tissue into coarse-fibrous one, and a higher content of mature connective tissue cells was determined in the second experimental group compared to the first experimental group (p < 0.05).

Conclusion. We have found that the most preferred modifications of textile woven vascular prostheses are antibacterial coatings without polyvinylpyrrolidone, which significantly reduce inflammatory reactions and enhance the fibroplastic properties of the prostheses during all follow-up periods.
Role of Trade-Related Aspects of Intellectual Property Rights (TRIPS) in Intellectual Property Rights (IPR) Legislation Laws in India
Authors: Goel Kamal , Singh Dr. Surinder
Published: April 2022

The world economy is growing through the development rate. Every day we come across new developments, inventions and innovations in the field of natural science, medical science, commerce and management etc. One of the main factors that are helping in these developments is strong IPR in the world by the introduction of TRIPS by the World Trade Organization (WTO). In this study, an attempt has been made to discuss the role of TRIPS in IPR legislation laws in India. The study is exploratory cum descriptive in nature. The study found that with the emergence of TRIPS it became obligatory for its member nation to follow its guidelines. In India various amendments has been done in the Patent Act, Copyrights act, Trademarks act to comply with the guideline of TRIPS. Major amendments include Abolition of exclusive market Rights, Terms of patents increased from 14 years to 20 years, Power of Government broadcasting organisations and performers in certain other countries in case of copyrights, registration of design, extension of definition of trademarks etc. Further geographical indication act came into existence where geographical indication cannot register as trademarks; protection of plant varieties and farmers’ rights also there is a three-tier body at local, state and national level that works for the preservation and conservation of biological resources. The study suggested that non-governmental organizations (NGOs) should take part in boosting the IPR.
Impacts of three types of solar geoengineering on the Atlantic Meridional Overturning Circulation
Authors: Xie Mengdie , Moore John C. , Zhao Liyun , Wolovick Michael , Muri Helene
Published: April 2022

Abstract. Climate models simulate lower rates of North Atlantic
heat transport under greenhouse gas climates than at present due to a
reduction in the strength of the Atlantic Meridional Overturning
Circulation (AMOC). Solar geoengineering whereby surface temperatures are
cooled by reduction of incoming shortwave radiation may be expected to
ameliorate this effect. We investigate this using six Earth system models
running scenarios from GeoMIP (Geoengineering Model Intercomparison Project)
in the cases of (i) reduction in the solar constant, mimicking dimming of
the sun; (ii) sulfate aerosol injection into the lower equatorial
stratosphere; and (iii) brightening of the ocean regions, mimicking enhancing
tropospheric cloud amounts. We find that despite across-model differences,
AMOC decreases are attributable to reduced air–ocean temperature
differences and reduced September Arctic sea ice extent, with no
significant impact from changing surface winds or precipitation − evaporation.
Reversing the surface freshening of the North Atlantic overturning regions
caused by decreased summer sea ice sea helps to promote AMOC. When comparing the
geoengineering types after normalizing them for the differences in top-of-atmosphere radiative forcing, we find that solar dimming is more effective
than either marine cloud brightening or stratospheric aerosol injection.

Abstract. An evaluation of aerosol microphysical, optical and
radiative properties measured with a multiwavelength photometer named
CW193 was performed in this study. The instrument has a highly integrated
design, smart control performance and is composed of three parts (the optical
head, robotic drive platform and stents system). Based on synchronous
measurements, the CW193 products were validated using reference data from the
AERONET CE318 photometer. The results show that the raw digital counts from
CW193 agree well with the counts from AERONET (R>0.989), with daily
average triplets of around 1.2 % to 3.0 % for the ultraviolet
band and less than 2.0 % for the visible and infrared bands. Good
aerosol optical depth agreement (R>0.997, 100 % within
expected error) and root mean square error (RMSE) values ranging from 0.006
(for the 870 nm band) to 0.016 (for the 440 nm band) were obtained, with the
relative mean bias (RMB) ranging from 0.922 to 1.112 and the aerosol optical
depth bias within ±0.04. The maximum deviation of the peak value for
fine-mode particles varied from about 8.9 % to 77.6 %, whereas the
variation for coarse-mode particles was about 13.1 % to 29.1 %. The deviation variations of the single scattering albedo were
approximately 0.1 %–1.8 %, 0.6 %–1.9 %, 0.1 %–2.6 % and 0.8 %–3.5 %
for the 440, 675, 870 and 1020 nm bands, respectively. For the
aerosol direct radiative forcing, deviations of approximately 4.8 %–12.3 %
were obtained at the earth's surface and 5.4 %–15.9 % for the top of the
atmosphere. In addition, the water vapor retrievals showed satisfactory
accuracy, characterized by a high R value (∼0.997), a small
RMSE (∼0.020) and a good expected error distribution (100 % within expected error). The water
vapor RMB was about 0.979, and the biases mostly varied within ±0.04,
whereas the mean values were concentrated within ±0.02.

Abstract. To compare the impact of surface–atmosphere exchanges from rural and urban areas, fully vegetated areas (e.g. deciduous trees, evergreen trees and
grass) commonly found adjacent to cities need to be modelled. Here we provide a general workflow to derive parameters for SUEWS (Surface Urban
Energy and Water Balance Scheme), including those associated with vegetation phenology (via leaf area index, LAI), heat storage and surface
conductance. As expected, attribution analysis of bias in SUEWS-modelled QE finds that surface conductance (gs) plays the
dominant role; hence there is a need for more estimates of surface conductance parameters. The workflow is applied at 38 FLUXNET sites. The derived
parameters vary between sites with the same plant functional type (PFT), demonstrating the challenge of using a single set of parameters for a
PFT. SUEWS skill at simulating monthly and hourly latent heat flux (QE) is examined using the site-specific derived parameters, with the
default NOAH surface conductance parameters (Chen et al., 1996). Overall evaluation for 2 years has similar metrics for both configurations:
median hit rate between 0.6 and 0.7, median mean absolute error less than 25 W m−2, and median mean bias error
∼ 5 W m−2. Performance differences are more evident at monthly and hourly scales, with larger mean bias error (monthly:
∼ 40 W m−2; hourly ∼ 30 W m−2) results using the NOAH-surface conductance parameters, suggesting that they
should be used with caution. Assessment of sites with contrasting QE performance demonstrates how critical capturing the LAI dynamics is
to the SUEWS prediction skills of gs and QE. Generally gs is poorest in cooler periods (more pronounced at
night, when underestimated by ∼ 3 mm s−1). Given the global LAI data availability and the workflow provided in this study, any
site to be simulated should benefit.
Seasonal variation and release of soluble reactive phosphorus in an agricultural upland headwater in central Germany

Abstract. Soluble reactive phosphorus concentrations (SRP) in agricultural headwaters can display pronounced seasonal variability at low flow, with the highest concentrations occurring in summer. These SRP concentrations often exceed eutrophication levels but their main sources, spatial distribution, and temporal dynamics are often unknown. The purpose of this study is therefore to differentiate between potential SRP losses and releases from soil drainage, anoxic riparian wetlands and stream sediments in an agricultural headwater. To identify the dominant SRP sources we carried out three longitudinal stream sampling campaigns on SRP fluxes. We used salt dilution tests and 222Rn to determine water fluxes in different sections of the stream, and carried out specific sampling for SRP, iron and 14C-DOC to examine possible redox-mediated mobilization from riparian wetlands and stream sediments. The results indicate that a single short section in the upper headwater reach was responsible for most SRP losses to the stream. Analysis of samples taken under summer low flow conditions revealed that the stream-water SRP concentrations, SRP-fraction for dissolved P (DP) and DOC radiocarbon ages matched those in the groundwater entering the gaining section. We argue that the seasonal variation of SRP concentrations was mainly caused by variations in the proportion of groundwater present in the streamflow, and was thus highest during summer low flow periods. Stream-sediment pore water showed evidence of reductive mobilization of SRP but the exchange fluxes were probably too small to contribute substantially to SRP stream concentrations. Examination of the combined results of this campaign and previous monitoring confirms that groundwater is also the main long-term contributor of SRP at low flow and that seepage from agricultural phosphorous is largely buffered in the soil zone. In this headwater, stream SRP loading during low flow is therefore mainly geogenic, while agricultural sources play only a minor role in SRP loading, with the dominant SRP sources being the local Paleozoic greywacke and Devonian shale. Because it is also possible for similar seasonal SRP dilution patterns to be generated by enhanced mobilization in riparian zones or wastewater inputs, precise knowledge of the different input pathways is important to the choice of effective management measures.
Development of an automatic thresholding method for wake meandering studies and its application to the data set from scanning wind lidar

Abstract. Wake meandering studies require knowledge of the instantaneous wake evolution. Scanning lidar data are used to identify the wind flow behind offshore wind turbines but do not immediately reveal the wake edges and centerline. The precise wake identification helps to build models predicting wake behavior. The conventional Gaussian fit methods are reliable in the near-wake area but lose precision with distance from the rotor and require good data resolution for an accurate fit. The thresholding methods, i.e., selection of a threshold that splits the data into background flow and wake, usually imply a fixed value or manual estimation, which hinders the wake identification on a large data set. We propose an automatic thresholding method for the wake shape and centerline detection, which is less dependent on the data resolution and quality and can also be applied to the image data. We show that the method performs reasonably well on large-eddy simulation data and apply it to the data set containing lidar measurements of the two wakes. Along with the wake identification, we use image processing statistics, such as entropy analysis, to filter and classify lidar scans. The automatic thresholding method and the subsequent centerline search algorithm are developed to reduce dependency on the supplementary data such as free-flow wind speed and direction. We focus on the technical aspect of the method and show that the wake shape and centerline found from the thresholded data are in a good agreement with the manually detected centerline and the Gaussian fit method. We also briefly discuss a potential application of the method to separate the near and far wakes and to estimate the wake direction.
Oścień z powodu ciała (2 Kor 12, 7–10). Kontekst, struktura, miejsce i funkcja w argumentacji Pawła

The conducted study has shown the validity of interpreting the syntagma σκόλοψ τῇ σαρκί as a dativus cause. It has also undertaken to interpret it in connection with the Pauline theology of the cross, which the Apostle developed in the earlier canonical First Letter to the Corinthians (1:18–2:16). The thorn given because of the flesh accomplishes Paul’s conformation to Christ in suffering. He confirmed his compassion with Christ by giving encouragement to follow Him as he does (1 Cor 4:16; 11:1; 1 Th 1:6). A significant result of the study undertaken has been the indication of the presence of prosapodosis, which logically explains the unnecessary redundancy in the text surrounding the phrase σκόλοψ τῇ σαρκί, which is not reflected in modern translations yielding the synonymous translation of the repetitive syntagma ἵνα μὴ ὑπεραίρωμαι. It has been shown that this construction in the text is not only a vehicle for irony, but also a means of attracting attention, indicating the essence of the message.
Reflexões e Diretrizes para o Estudo da Paisagem Vernacular
Authors: Frank Bruno José Rodrigues , Tetsuya Yamaki Humberto
Published: April 2022

O conceito de Paisagem Vernacular foi utilizado pela primeira vez por J.B Jackson, ensaísta estadunidense que procurou interpretar e valorizar as paisagens comuns observadas nos Estados Unidos da América. E, desde então, esse conceito vem sendo trabalhado dentro dos estudos de Paisagem Cultural. A despeito da riqueza de interpretações possíveis, a Paisagem Vernacular não possui um tratamento teórico e metodológico sistemático. Este artigo procura preencher esta lacuna e para isso procuramos conceituar o termo e procurar pelas particularidades que diferencia das demais categorias de Paisagem Cultural. Em seguida definimos quais diretrizes e parâmetros de análise podem ser utilizados para seu estudo, seguido das abordagens mais relevantes de pesquisa. O artigo traz ainda o exemplo de um estudo com a Paisagem Vernacular no norte do Paraná, tendo como exemplo a localidade Invernada, onde são aplicados alguns dos parâmetros discutidos no texto.
