HUMOROUS ANECDOTES AS MOTIVATIONAL TOOL IN PURPOSIVE COMMUNICATION
Authors: Albores Cecil , Alda Rivika
Published: September 2023

With the demands of effective pedagogy for the 21st century, teachers are in constant search for a teaching tool that is more fun, and interesting and promotes positive learning. Thus, this study ascertained the effectiveness of humorous anecdotes as a motivational tool in improving students’ performance in Purposive Communication. Using a quasi-experimental design, the student's speaking and writing performances were evaluated and the humorous anecdotes as a motivational tool served as a treatment for the experimental group and other different motivational tools were employed in the control group. Focus group discussion was also used to obtain students’ narratives during the implementation. The findings assert that the participants taught with humorous anecdotes as a motivational tool exemplify the description of needs improvement for writing skills and noted deficient in speaking skills but with noticeable little progress. Despite little developments observed, the mean gains of the entry and exit performance levels in both skills and groups were comparable. In a deeper sense, humor in this study promotes a heartwarming teaching-learning process and an efficient teacher-student relationship. It is recommended that initiatives to augment the relevance of using humor in motivation may be considered by language teachers.
APPLICATION AND COMBINATION OF DIFFERENT FOREIGN LANGUAGE TEACHING METHODS IN ESP CLASSROOM
Authors: Tenieshvili Anna
Published: September 2023

English for Specific Purposes (ESP) being separate branch of the English Language requires specific approach during the process of teaching.  Application of right methodology of teaching is very important for successful ESP teaching, therefore correct selection and combination of different foreign language teaching methods are crucial to ensure that the required results are achieved in the ESP classroom. When working in the ESP classroom ESP teachers base their teaching approach on the principle: “English for Specialty” rather than on the principle: “Specialty in English” the approach characteristic of Content and Language Integrated Learning (CLIL). In our paper we are going to discuss the ways of efficient combination of Grammar-Translation method and Audio-Lingual method using ESP textbooks and materials and also development of listening and speaking skills of ESP learners through different subject videos selected on the basis of linguistic abilities and knowledge of specific terminology by ESP learners. Some of these videos are available on YouTube and other internet platforms. Elements of CLIL approach that imply complete immersion into language and subject matter can be applied in ESP classroom. Their combination with the above-mentioned foreign language teaching methods is possible, especially in those groups of ESP learners whose level of General English is B2 and higher. The parallel can be made between CLIL in ESP teaching environment and Direct method of foreign language teaching in General English teaching environment. In this way we compare partial application of CLIL approach in the ESP classroom to the Direct method of foreign language teaching when it refers to teaching of General English. The main aim of our paper is to consider combination of the following foreign language teaching methods and the methodology of CLIL as the most suitable and efficient way of teaching English for Specific Purposes in the classroom:1) Grammar-Translation method;2) Audio-Lingual method;3) Direct method with elements of CLIL approach when applied in the ESP classroom.

Authors: Carvalho de Almeida Prado Malila , Terenzi Daniela , Tosqui-Lucks Patricia , Zhou Ziqian
Published: September 2023

This paper describes collaborative work by two higher education institutions in Brazil and China that joined forces to build a corpus with a view to investigating the language of aircraft maintenance documentation for teaching and lexicography purposes. The corpus consists of three languages, including English, with Chinese and Portuguese still under construction. The paper opens with an overview of language-related studies in the aircraft maintenance field, drawing attention to this specific niche and its demands. It discusses trials already performed with the English and Chinese sub-corpora, challenges faced, and the importance of task-sharing in multidisciplinary teams. It emphasizes the need to combine linguistics and professional expertise not only to develop materials for the aviation industry but also to assist the development of trainees who can experience a professional setting during their education. The corpus will be used in (among others) preparing pedagogical material for teaching not only aircraft maintenance personnel but also pilots and air traffic controllers. The corpus will also serve as a lexicographic resource for designing a visual dictionary with collocates and constructing trilingual glossaries.
Do We Really Not Know What Toulmin’s Analytic Arguments Are?
Authors: Kollárik Tomáš
Published: September 2023

The aim of this paper is to challenge the idea that Toulmin’s main focus in The Uses of Argument is to critique formal deductive logic. I first try to challenge the argument that, on the basis of what Toulmin says about analytic arguments, it is impossible to determine exactly what they are. I will then attempt to determine the basic contours of analytic arguments. Finally, I will conclude that the concept of an analytic argument involves epistemological assumptions to which formal logicians are in no way committed by the nature of their discipline.

Authors: Liang Xiangfeng , Wu Jili , Kai Xizhou , Zhao Yutao
Published: September 2023

This study investigated the creep performance, fracture characteristics,
and creep mechanisms of the nickel-base single crystal superalloy DD406
under conditions of 1100°C and 140MPa. The results indicate that the
alloy exhibited a creep life of 104.5 hours and a strain of 33.58%. The
creep curve exhibited three distinct stages: initial (deceleration),
steady-state, and accelerated creep. The fracture surface was
characterized by dimples and tearing edges, with no apparent slip
planes. Internal to the fracture, oxidation products and recrystallized
structures were observed, and the internal pores exhibited elongated
shapes oriented perpendicular to the stress axis. Furthermore, analysis
of the creep rate-time curve revealed three sub-stages within the
initial (deceleration) creep stage, where the creep rate decreased
initially, followed by an increase and subsequent decrease with time.
Rice ULTRAPETALA1 Regulates Developmental Reprogramming to Promote Resilience to Salinity Stress

Published: September 2023

Rice, one of the most agronomically important crops, has been challenged
by high salinity that affects its growth at the seedling stage and
reproductive phase. Thus, investigating the intricate molecular
mechanisms that regulate its developmental process throughout its life
cycle is essential for better stress resilience. In this study, we have
investigated the role of rice trithorax group factor ULTRAPETALA (
OsULT1) that orchestrates rice development and stress response. A
genome-wide chromatin immunoprecipitation analysis revealed enrichment
of OsULT1 to transcription factors and regulators, oxidative
stress signaling, ROS scavengers, and K uptake
transporters, during salinity stress. Interestingly, loci associated
with root development, plant height, inflorescence development,
panicles, spikelet numbers, and seed development also showed
OsULT1 occupancy under control and salt stress. OsULT1
transcriptionally regulates these loci during stress response by
modulating H3K4me3 and H3K27me3 modifications. OsULT1
overexpression ( OsULT1-3) causes developmental changes in rice
with enhanced plant height, increase in basal internode length; robust
root architecture; increase in tiller and panicle numbers. Moreover,
OsULT1-3 showed salinity tolerance with enhanced seed
germination, reduced ROS content, low Na /K
ratio in shoot and root tissue, and enhanced
post-stress recovery. Collectively, our results indicate that ULT1
regulates different developmental pathways for better protection and
adaptation against environmental stress.
Thermal limits of survival and reproduction depend on stress duration: a case study of Drosophila suzukii
Authors: Ørsted Michael , Willot Quenin , Olsen Andreas , Kongsgaard Viktor , Overgaard Johannes
Published: September 2023

Studies of ectotherm responses to heat extremes often rely on assessing
absolute critical limits for heat coma or death (CT),
however, such single parameter metrics ignores the importance of stress
exposure duration. Furthermore, population persistence may be affected
at temperatures considerably below CT through
decreased reproductive output. Here we investigate the relationship
between tolerance duration and severity of heat stress across four
ecologically relevant life-history traits (productivity, sterility,
coma, and mortality) using the global agricultural pest Drosophila
suzukii. For the first time, we show that for sublethal reproductive
traits, tolerance duration decreases rapidly and exponentially with
increasing temperature (R>0.97), thereby
extending the Thermal Death Time framework recently developed for
mortality and coma. Using field micro-environmental temperatures, we
show how thermal stress can lead to considerable reproductive loss at
temperatures with limited heat mortality highlighting the importance of
including limits to reproductive performance in ecological studies of
heat stress vulnerability.
Sex Differences in Alcohol-Cue-Induced Craving and Heart-Rate Variability in Hazardous Drinkers
Authors: Firdaus Insan , Huizink Anja , Kleiboer Annet , Goudriaan Anna , Kaag Anne Marije
Published: September 2023

The prevalence of hazardous drinking among females has increased more in
the past decades as compared to among males. While it is well-known that
females suffer more from the negative effects of alcohol use than males,
the mechanisms that explain sex differences in hazardous drinking remain
poorly understood. The current study aimed to investigate sex
differences in the relationship between cue-induced (relief and reward)
craving and cue-induced heart rate variability in a sample of hazardous
drinkers. One hundred fourteen hazardous drinkers (61 females) underwent
an alcohol cue-exposure paradigm consisting of exposure to
alcohol-related pictures, personalized script imagery, and alcohol
paraphernalia. Relief- and reward cravings were measured before and
after exposure using the Desire for Alcohol Questionnaire. Heart Rate
Variability was measured continuously during the exposure using an
electrocardiograph. While there was a significant increase in both
reward and relief craving following the alcohol exposure paradigm, these
effects were not moderated by sex. Importantly, however, exposure to
alcohol cues was associated with a stronger reduction in Heart Rate
Variability among males compared to female hazardous drinkers. Lastly,
exposure-related reduction in Heart Rate Variability was significantly
stronger in individuals that reported more exposure-induced relief
craving, but these effects were not moderated by sex. In summary, our
findings suggest that while there were no sex differences in
exposure-induced Heart Rate Variability, there was in exposure-induced
craving. These findings may pave the way for developing sex-specific
interventions specifically targeting Heart Rate Variability, including
Heart Rate Variability biofeedback.
Land subsidence, sea level rise, and enhanced tidal intrusion: unveiling the land loss and nuisance flooding potential in the Barataria Basin, Louisiana
Authors: Kang Byungho , Xie Surui
Published: September 2023

We found a persistent increase in landward tidal attenuation in the
Barataria region, indicating an increased risk of tidal intrusion over
time. We inferred significant land subsidence rate changes with
historically mapped land areas. By 2045, high tides will increase
Barataria’s land inundation, widening the land area gap between MSL and
MHHW. Abstract This study investigates land loss and coastal inundation
in Louisiana’s Barataria Basin, a region highly susceptible to
anthropogenic pressures and natural factors like land subsidence,
sea-level rise, and tidal dynamics. Using high-resolution Digital
Elevation Models (DEM) and water level data from the Coastal Reference
Monitoring System (CRMS) stations, we analyzed changes in land area and
water levels between 2007 and 2022. The attenuation coefficient
magnitude of tidal intrusion, which quantifies tidal amplitude reduction
as a function of landward distance from the coastline, exhibited a
persistent decrease from 2007 to 2022 for O1 and K1 (the dominant tidal
constituents), with an accumulated decrease of nearly 20%, signaling
enhanced hydrological connectivity across the region. We also projected
land area for historic years and predicted it for future years up to
2075, based on a range of displacement rates to account for
uncertainties in vertical land motion. Our analyses predict that, in the
absence of human intervention, the significance of tidal variations in
influencing land loss will escalate; by 2045, the land area estimated
based on Mean Higher High Water (MHHW) will constitute approximately
65% of the land area estimated using Mean Sea Level (MSL). Our findings
underline the importance of considering the compound effects of
subsidence, sea-level rise, and tidal dynamics in future land loss
mapping and flood risk assessments.
Water Quantification of Amorphous and Crystalline Ferric Sulfates Relevant to Mars
Authors: Meng Fan , Shi Erbin , Liu Changqing , Ling Zongcheng
Published: September 2023

Crystalline ferric sulfates (e.g., ferricopiapite and Fe(OH)SO4) have
been proposed at multiple locations on Mars by the orbiter. While at
Meridiani Planum and Gale Crater by rover missions, amorphous ferric
sulfates were also suggested to exist in soils and sedimentary rocks.
The ferric sulfates with different hydration degrees may play a key role
in the water cycle on Mars. In order to understand in detail the role of
the hydrated ferric sulfates in the water cycle and their exact
hydration states on Mars, twelve ferric sulfates with different
hydration states containing five crystalline ferric sulfates and seven
amorphous ferric sulfates were synthesized in the laboratory. The water
content (number of H2O molecules) was quantified by Raman spectroscopy
and Laser-induced breakdown spectroscopy (LIBS), respectively. It was
found that the amorphous ferric sulfates water content has a good
relationship with the SO4 tetrahedron main Raman feature position around
1000 cm-1, the intensity and area of water feature around 3500 cm-1 over
SO4 tetrahedron main Raman feature around 1000 cm-1, respectively.
Twelve ferric sulfates’ Hα emission line area at 656.7 nm is normalized
by the O emission line area at 778 nm in LIBS spectra. The crystalline
and amorphous ferric sulfates all showed a good relationship between the
values of normalized results and the water content. These results will
aid us in precisely constraining the exact phases of hydrated ferric
sulfates, provide a better reference for ChemCam, SuperCam, and SHERLOC
data interpretation and their use to quantify the water content in
detected targets.
Astronomically-paced changes in paleoproductivity, winnowing, and mineral flux over Broken Ridge (Indian Ocean) since the Early Miocene

Published: September 2023

A significant shift in Earth’s climate characterizes the Neogene,
transitioning from a single-ice-sheet planet to the current bipolar
configuration. This climate evolution is closely linked to changing
ocean currents, but globally-distributed continuous high-resolution
sedimentary records are needed to fully capture this interaction. The
Ocean Drilling Program (ODP) Site 752, located on Broken Ridge in the
Indian Ocean, provides such a Miocene-to-recent archive. We use X-ray
fluorescence (XRF) core scanning to build an eccentricity-tuned
age-depth model and reconstruct paleoceanographic changes since 23 Ma.
We find two intervals of enhanced productivity, during the early and
middle Miocene (18.5 – 13.7 Ma) and late Pliocene/early Pleistocene (3
– 1 Ma). We also report a mixed eccentricity-obliquity imprint in the
XRF-derived paleoproductivity proxy. In terms of grain size, three
coarsening steps occur between 19.2 – 16 Ma, 10.8 – 8 Ma, and since
2.6 Ma. The steps respectively indicate stronger current winnowing in
response to vigorous Antarctic Intermediate Water flow over Broken Ridge
in the early Miocene, the first transient onset of Tasman Leakage in the
Late Miocene, and the intensification of global oceanic circulation at
the Plio-Pleistocene transition. High-resolution iron and manganese
series provide a detailed Neogene dust record. This study utilized a
single hole from an ODP legacy-site. Nevertheless, we managed to provide
novel perspectives on past Indian Ocean responses to astronomical
forcing. We conclude that Neogene sediments from Broken Ridge harbor the
potential for even more comprehensive reconstructions. Realizing this
potential necessitates re-drilling of these sedimentary archives
utilizing modern drilling strategies.

The Sudan-Sahel region has long been vulnerable to environmental change.
However, the intensification of global warming has led to unprecedented
challenges that require a detailed understanding of climate change for
this region. This study analyzes the impacts of climate change for
Burkina Faso using eleven climate indices that are highly relevant to
Sudan-Sahelian societies. The full ensemble of statistically downscaled
NEX-GDDP-CMIP6 models (25 km) is used to determine the projected changes
for the near (2031-2060) and far future (2071-2100) compared to the
reference period (1985-2014) for different SSPs. Validation of the
climate models against state-of-the-art reference data (CHIRPS and ERA5)
shows reasonable performance for the main climate variables with some
biases. Under the SSP5-8.5, Burkina Faso is projected to experience a
substantial temperature increase of more than 4.3°C by the end of the
century. Rainfall amount is projected to increase by 30% under the
SSP5-8.5, with the rainy season starting earlier and lasting longer.
This could increase water availability for rainfed agriculture but is
offset by a 20% increase in evapotranspiration. The country could be at
increased risk of flooding and heavy rainfall in all SSPs and future
periods. Due to the pronounced temperature increase, heat stress,
discomfort, and cooling degree days are expected to strongly increase
under the SSP8.5 scenarios, especially in the western and northern
parts. Under the SSP1-2.6 and SSP5-8.5, the projected changes are much
lower for the country. Thus, timely implementation of climate change
mitigation measures can significantly reduce climate change impacts for
this vulnerable region.
Antiextremistische Reichweite der Kontroversität an Schulen?
Authors: Feldmann Dominik
Published: September 2023

Der folgende Kommentar richtet das Augenmerk auf die Frage, wie weit Kontroversität in politischen Debatten an Schulen reichen sollte. Johannes Drerup schlägt in seiner Studie „Kontroverse Themen im Unterricht“ dazu unter anderem ein politisches Kriterium vor, um die Reichweite von Kontroversität zu bestimmen. Der Orientierungsrahmen dafür besteht nach Drerup aus liberal-demokratischen Grundwerten. Tasten Positionen diese an, sollten diese nicht Teil politischer Kontroversen an Schulen sein. Doch sind solche Werte klar zu bestimmen und eignen sie sich zur didaktischen Konkretion an Schulen? So sinnvoll beispielsweise normative Bezüge zu Menschenrechten sind, so oft werden sie im politischen Alltag in Deutschland und darüber hinaus verletzt – von unterschiedlichen Akteuren. Sollte nicht eine kritische Auseinandersetzung mit der Missachtung von Menschenrechten Gegenstand schulischer Bildungsarbeit sein anstatt damit zusammenhängende Positionen aus der Kontroverse auszuschließen? Besonders problematisch erscheint es, das Extremismuskonzept heranzuziehen, um solche Akteure zu charakterisieren, die liberal-demokratische Werte mutmaßlich verletzen. Schließlich gibt es einerseits auch in der politischen Mitte und staatlichen Apparaten demokratiegefährdende Tendenzen. Andererseits kann das Label „extremistisch“ genutzt werden, um missliebige Positionen im politischen Streit willkürlich zu schwächen. Welche Positionen aus Sicht von Schüler*innen eine Bedrohung für demokratische Gesellschaften darstellen, sollte im Rahmen politischer Bildung abgewogen werden, nicht jedoch a priori feststehen.
Was heißt es, konstruktiv zu streiten
Authors: Lanius David
Published: September 2023

Drerup (2021) argumentiert dafür, dass Kontroversen im Unterricht eingesetzt werden sollten, um demokratische Grundbildung zu fördern. Als Bildungsziel ist die Förderung demokratischer Grundbildung in seiner Allgemeinheit sicherlich klar zu befürworten, ob der Einsatz von Kontroversen jedoch ein geeignetes und verhältnismäßiges Mittel dafür ist, kann pauschal nicht so leicht beantwortet werden. Schließlich hängt ihre Eignung und Verhältnismäßigkeit ganz maßgeblich davon ab, welche kontroversen Themen im Unterricht auf welche Weise diskutiert werden. Um hier zu einem fruchtbaren Ergebnis zu gelangen, muss zunächst allerdings eine grundlegende Frage beantwortet werden – nämlich, was es überhaupt heißt, konstruktiv zu diskutieren. Dann können nämlich mögliche Funktionen von kontroversen Diskussionen identifiziert und darauf aufbauend sowohl einzelne Ziele, geeignete Themen als auch die jeweiligen Rahmenbedingungen in eine konkrete Beziehung gesetzt werden. So sind die allgemeinen Leitlinien für eine gelingende Praxis, wie Drerup sie formuliert, zwar ausgesprochen hilfreich, aber ob eine Praxis tatsächlich gelingt, kann ohne eine solche Verzahnung zwischen Zielen, Themen und Bedingungen in den meisten Fällen kaum hinreichend geklärt werden. Wenn wir die pädagogisch-didaktischen Ziele jedoch allgemein in der Förderung von individueller und politischer Autonomie und demokratischer Grundbildung sehen, dann müsste man, so die zentrale These des vorliegenden Beitrags, sehr viel mehr zur Qualität von Diskussionen und insbesondere zur Güte von Argumentationen sagen, um dann geeignete Themen und passende Rahmenbedingungen genauer zu bestimmen. Nichtsdestoweniger ist Drerups Band eine enorme Bereicherung für die Debatte.
Verlangsamung und Stillstand

Published: September 2023

Zu den Symptomen medizinisch depressiver Menschen gehört manchmal eine veränderte Zeiterfahrung, die als quälend empfunden wird. Die Zeit verlangsamt sich bis hin zum Eindruck des Stillstandes der Zeit. Diese Psychopathologie der Zeit wird hier als extremes Beispiel für etwas angesehen, das es in schwächerer Form auch nicht-pathologisch gibt und das als solches auch ein Thema für philosophische Theorien des guten Lebens darstellt. Die Untersuchung der pathologischen Störungen dient als Negativfolie, um zu zeigen, wie im Fall gelingenden Lebens menschliches Zeitbewusstsein verfasst sein muss bzw. verfasst ist. Offenbar sind wir auf die Erfahrung einer fortlaufenden Zeit angewiesen. In diesem Aufsatz wird erörtert, welcher Art genau diese Erfahrung ist, auf welche verschiedenen Weisen sie gestört sein kann und inwiefern solche Störungen ein ethisches Problem sind, insofern sie die Lebensführung in grundsätzlicher Hinsicht beeinträchtigen. Dafür wird insbesondere zwischen einem basalen und einem personalen Zeitbewusstsein unterschieden und das Problem auf der zweiten Ebene verortet.

Static mixers are becoming increasingly popular because they are
energy-efficient, cost-effective, and easy to maintain. Mixing is an
essential unit operation in many chemical industries. In this study, a
modified high efficiency vortex static mixer was used to examine laminar
flows in a rectangular duct. To encourage fluid rotation and improve mixing
with heat transfer, the modified high efficiency vortex set was rotated by
angles of 0?, 5?, 10?, 20?, 25?, and 30?. The Reynolds number varied from
3000 to 8000. The outcomes demonstrated that the performance of the mixing
was significantly impacted by the modified high efficiency vortex set. The
highest mixing efficiency was achieved with a rotation angle between 15?
and 20?. Furthermore, the rotations reduced pressure loss in the system and
enhanced heat transfer performance, by creating vortices. These results
show how modified high efficiency vortex static mixers can improve mixing
and heat transfer efficiency in turbulent flows, with prospective
utilization across diverse chemical sectors.

Comparison of the efficiency of wind power plants from renewable energy types to reduce atmosphere pollution in Marmara region
Authors: Simsek Suleyman , Dogan Funda
Published: September 2023

Our need for energy is increasing every day with the advancement of
technology. Energy plays a major role in the social and economic sphere of
life. The need for RES is increasing day by day although the need for energy
is produced from fossil fuels in many countries. In addition to this, while
the harmful gases emitted to the environment as a result of using fossil
fuel for energy production harm the nature, this is not possible in
renewable wind energy. Renewable wind energy is an endless source of energy
obtained from natural processes. Therefore, wind power stations get
attention of many countries. The wind industry is the world's
fastest-growing energy source. However, the main problem of the renewable
wind energy sector is that the desired wind intensity cannot be sustained at
the same rate and the installation costs are high. Many countries are aware
of the importance of wind energy and make certain investments in renewable
wind energy in the long term. Wind turbines can be in different shapes
according to their location and intended use. One of the most important
reasons for their different designs is the wind types in their geographies.
In this study, wind power plants in five different regions in Marmara region
were discussed. These plants were com-pared among themselves, the results
were evaluated and the efficiency of the plants compared.

Published: September 2023

The increasing need for clean water depending on the world?s population has
accelerated efforts to re-evaluate the use of water. This has led to the
spread of wastewater treatment plants (WWTP). Sewage sludge (SS), which is
the waste of WWTP, is increasing due to the increase in the number of
plants. As a result, the disposal and evaluation of SS, which is waste, has
accelerated. In this study, re-searches were carried out on different usage
areas of SS, which is WWTP waste. The SS was first dried. After the drying
process, the SS was subjected to physical and chemical activation processes
and turned into activated carbon. Activated carbons were obtained at
different operating temperatures. The FT-IR, XRD, ICP-MS, TG-DTA, CHNS,
SEM-EDX analyzes were performed for the obtained activated carbons.
According to the results of the analysis, the selected activated carbons
were mixed with diesel fuel at 50 ppm and 100 ppm ratios. The effects of
fuel mixtures prepared with diesel fuel in terms of engine performance,
combustion and emissions are investigated. Engine performance and exhaust
emission measurements were made in a 6-cylinder Diesel engine at a constant
speed of 600 rpm and under five different loads (0 Nm, 50 Nm, 100 Nm, 150
Nm, and 200 Nm). Emission values were measured as CO, HC, CO2, O2, and NOx
and comparative assessments were made. In this study, the positive effects
of SS-derived activated carbons on the engine were determined by using it as
a diesel fuel additive.

Cavitating Venturis are simple apparatus used as a flow meter over a broad
range of mass-flow rates. The main objective of this work is to introduce
obstacles in small-sized cavitating Venturis in order to increase their
capacity by raising the critical pressure, i.e. widens the phase of the
cavitating mode. Four configurations have been tested depending on the
location of these obstacles. This study focused on investigating the
numerical performance of cavitating Venturis with different downstream
pressures by employing the k-? SST turbulence model and the Rayleigh-Plesset
equation for modeling cavitation. The governing equations were solved using
the finite volume method, employing the Rhie and Chow pressure-velocity

Enhancing the durability of molds, jigs, and tools is crucial for the industry, and one approach to achieve this is by forming a metallic layer with high hardness on their surfaces. Metallic layers with high hardness can be formed through laser metal deposition (LMD), which is one of the additive manufacturing processes, using cemented carbide powder. However, crack initiation typically occurs inside cemented carbide layers formed by the LMD. Therefore, achieving a cladding process for cemented carbide layers without cracks is desired for practical applications. In this study, the effects of tungsten carbide (WC) ratios in WC-Co cemented carbide granulated powder on formed bead size and crack initiation during the LMD processing were investigated. The number of cracks generated during the LMD processing was evaluated using an acoustic emission (AE) technique. The number of burst-type AE signals generated was counted as the number of cracks. Seven types of WC-Co cemented carbide granulated powders with WC ratios ranging from 30.5 to 92 mass% were prepared. Beads were formed using each powder through the LMD, with AE signals being measured. In the case of a WC ratio of 42.9 mass% or less, no crack was observed. On the other hand, cracks were observed when the WC ratio was 53.9 mass% or greater, and the number of cracks increased with an increase in the WC ratio.

Background: The prevalence of end-stage renal disease (ESRD) requiring dialysis has progressively increased. Therefore, to achieve financial stability by managing the increasing numbers of patients undergoing hemodialysis (HD), a fixed-payment system was introduced in 2001 for medical aid (MA) beneficiaries receiving HD in Korea. Methods: We identified patients in the Korean Renal Data System that received HD between 2001 and 2017 and stratified them into the following two groups: the National Health Insurance (NHI) and MA groups. Then, we compared the two groups that differed in demographic characteristics, the treatment process and outcomes, and mortality based on health insurance type. Results: Among 52,574 patients, the number of patients aged 65 years or older, hypertension was higher in the NHI group, but diabetes was higher in the MA group. Additionally, the MA group had more weekly dialysis sessions, and expensive drugs tended to be used less frequently. Regarding treatment outcomes, including laboratory test results, the MA group achieved significantly lower goals than the NHI group (p < 0.001). Furthermore, the mortality rate per 1,000 persons was 31 and 27 in the MA and NHI groups, respectively, and the mortality rate ratio was 1.2 (95% confidence interval [CI], 1.076–1.230). Moreover, the hazard ratio for mortality was 1.39 (95% CI, 1.30–1.49, p < 0.001) after adjusting for age, sex, causes of ESRD, and comorbidities. Conclusion: There were significant differences in the treatment and mortality indicators between the groups. Therefore, policy support should be strengthened to provide better medical services to MA beneficiaries undergoing HD.

Authors: B Deivasigamani
Published: September 2023

The fish production in the country in 2022 was 8.13 million tonnes, of which 4.2 million tonnes was contributed by the marine sector and the rest by inland sector. Fish and fish products accounted for approximately Rs.9,200 crore towards country’s exports, which constitutes 20% of the national agricultural exports. Marine fisheries sector forms the source of livelihood for over 7.5 million traditional fishermen inhabiting about 5,600 coastal fishing villages situated along the country’s coastal belt. It provides direct and indirect employment for several million people in fishing, processing, trading and ancillary activities. The present study aims to find out the marketing problems of fisherman in Chidambaram and Parangipettai Villages in the Cuddalore District. A large number of people are concerned with fish production, distribution and marketing systems in both the fish markets of the Cuddalore District, viz., the Chidambaram fish market and the Parangipettai fish market. The main aim of this study is to describe the present status of fish marketing system of fish and dry fish products. The description is based on primary data and secondary data collected in the different markets.

Published: September 2023

Background: The opportunistic fish pathogen are the main cause of mass mortality in several fish species and severe economic losses in different countries. This study was conducted to determine occurrence and characterization of Enterococcus faecalis from infected farmed African catfish in Ogun State, Nigeria. Methodology: The bacteria was isolated from infected farmed African catfish (Clarias gariepinus, n=128) with clinical signs of atrophied or reduced barbels, desquamation or abrasion of the skin, and ascites were purposively sampled in Ogun State. The isolates were identified based on morphological, biochemical tests, and 16S rRNA molecular characterization. The 16S rRNA gene sequence was analyzed using BLAST, submitted to the NCBI database, and an accession number was generated. Results: The percentage occurrence of Enterococcus faecalis isolates in infected Clarias gariepinus from Ogun State were; Ogun East 30.00% (18/60); Ogun Central 17.86% (5/28); Ogun West 12.50% (5/40). The highest incidence (p < 0.05) in Ogun State recorded was in Ijebu Ode local government compared to other local governments area. All Enterococcus faecalis isolates in this study were non-motile, gram-positive cocci, showed negative reaction for catalase, negative for oxidase, negative for methyl-red, and negative for indole. 16S rRNA gene of Enterococcus faecalis isolates in infected Clarias gariepinus from Ogun State, Nigeria (OP595802.1) was closely related to 16S rRNA gene of other Enterococcus faecalis isolates Conclusions: The bacteria isolated from infected farmed Clarias gariepinus in Ogun State, Nigeria was Enterococcus faecalis, and showed an evolutionary relationship with NCBI reference global strains from different countries.

Espanha na Cimeira das Lajes: o fim do consenso na política externa
Authors: García Pérez Rafael , Iglesias Cavicchioli Manuel
Published: September 2023

A chamada «Cimeira das Lajes» marca um ponto de viragem de enorme relevância na política externa espanhola. Denunciada pelo conjunto da oposição política como o paroxismo da posição belicista de José María Aznar e reivindicada por ele como o apogeu da sua política externa, a Cimeira das Lajes é o símbolo de um período tremendamente agitado da política espanhola. Este artigo analisa a importância desta cimeira como ponto de viragem de uma mudança muito profunda no modelo de política externa até então implementado. Será também prestada atenção ao significado da cimeira no seu vigésimo aniversário e à forma como marcou, em grande medida, o desenvolvimento da política externa de Espanha, apesar das duas décadas volvidas.
A rejeição da Constituição refundacional chilena
Authors: Borges Santos Paula
Published: September 2023

Depois de terem rejeitado de forma inequívoca o texto de uma nova Constituição, no referendo de 4 de setembro de 2022, os chilenos optaram por atribuir a maioria dos lugares para o Conselho Constituinte, na eleição de 7 de maio de 2023, ao Partido Republicano, liderado por José António Kast. Estes resultados representam retrocessos significativos para o Governo do Presidente Gabriel Boric. Este artigo apresenta quatro razões principais que explicam esta realidade: desilusão com o trabalho da Convenção e com a radicalidade da proposta de Constituição elaborada; insatisfação com o design institucional estabelecido para a segunda fase do processo constitucional; as regras eleitorais aplicadas; e a crise de segurança existente que erodiu a confiança do eleitorado no Governo de Boric.
neoliberalismo do tempo presente e a urgência de uma justiça de transição pós-neoliberal
Authors: Lemos Tayara Talita , Quinalha Renan
Published: September 2023

A partir da compreensão de que a transição da ditadura empresarial-militar brasileira (1964-1985) para a democracia foi marcada por privilegiar os interesses das elites econômicas em prejuízo da classe trabalhadora, pretende-se investigar em que medida o neoliberalismo do tempo presente pode ser caracterizado como sucessão do modelo governamental daquele período. Com a intensa abertura da agenda política ao capital privado, especialmente entre 1967 e 1978, percebeu-se a aliança estabelecida entre empresas e estado, num processo de neoliberalização, caminhando ao lado da construção do mito do “milagre econômico”. Busca-se avaliar, por meio de revisão bibliográfica, se as recentes propostas neoliberais que, entre muitos impactos econômicos, desmontam direitos trabalhistas e fragmentam a classe trabalhadora, podem ser parte do que resta da ditadura e de uma justiça de transição que desconsiderou, em grande medida, uma dimensão econômica das violações de direitos humanos cometidas pelo regime.
