Mutual Fund in Kotak Mahindra Bank
Authors: Raj Priti
Published: April 2024

Abstract: The use of mutual funds as a safety net for one's finances is on the rise. The industrial sector's performance has boosted India's economic narrative, and mutual funds have lowered the barrier to entry for households looking to invest. More and more people are becoming aware of mutual funds and the advantages they offer. Most people don't invest in mutual funds because, for example, 90% of wage workers in India are unaware that they exist. One out of five individuals may decide to put their money into a mutual fund when they find out what possibilities are available to them. To effectively market mutual funds to someone who is unfamiliar with them, one must first identify the type of people who are inclined to purchase them and then provide reasons that they will see as substantial. Working on this piece was a terrific learning experience and gave me a lot of practice with analysis. Investors' saving and investing habits, mutual fund preferences, and other market research topics are examined and recommended in this paper report.
Design and Implementation on Industrial Automation with the help of Renewable Energy Sources
Authors: Swapna Prof. God
Published: April 2024

Abstract: In the quest for a sustainable future, we’ve identified that traditional street lighting consumes more electricity than necessary. To address this, we’ve conceptualized an energy-efficient street lighting system. Our prototype leverages a Light Detecting Resistor (LDR) to optimize power usage, paving the way for an eco-friendly world. Fire alarms are crucial for timely fire detection, safeguarding lives and property. Our simplified circuit design enhances reliability, forming an integral part of a comprehensive security system that relies on sensor technology for prompt fire detection. The demand for automation is surging in both industrial and domestic spheres. This paper aims to minimize manual intervention by introducing self-operating systems powered by renewable energy sources. We’re integrating solar technology and piezoelectric sensors to harness electricity. This approach not only fuels industrial automation but also contributes to the global shift from finite conventional energy to renewable sources. By employing sensors, we ensure safety and efficiency in industrial zones while generating clean energy.

A Complexity Ladder for Big History
Authors: Nielsen J. N.
Published: April 2024

Complexity is a central problem for big history because big history has made complexity a central theme, constructing a cosmological periodization based on the sequential emergence of qualitatively distinct forms of complexity. How can the big historian differentiate distinct thresholds of emergent complexity while subordinating the entire sequence of thresholds to a single metric of complexity that demonstrates the increase of complexity over multiple scales of magnitude and across qualitatively distinct forms of complexity? The cosmologists’ use of a cosmic distance ladder suggests an analogous construction for complexity: a complexity ladder for big history. While no complexity ladder is formulated in this paper, the program required for a complexity ladder is sketched.
On Trends and Periods in Big History
Authors:   The London School of Hygiene & Tropical Medicine, Aunger Robert
Published: April 2024

Over nearly fifty years, Big History has evolved as an interdisciplinary approach, connecting cosmic, geological, biological, and cultural phenomena into a unified narrative of increasing complexity. This paper critically examines various theoretical frameworks within Big History, focusing on their scientific soundness. While progress has been made, challenges persist in establishing a theoretical core and achieving consensus. Commonalities exist, such as the recognition of a trend toward increasing complexity, the division into temporal eras and periods, and the acknowledgment of unique dynamics defining these phases. However, a consensus on the best foundational principles and canonical periods remains elusive. The paper suggests three strategies for theory development: employing cross-disciplinary theories, generalizing discipline-specific theories, or inventing novel theories. Each approach requires further refinement and empirical testing to contribute to consensus building. Big History is argued to have utility based on its ability to contextualize events within a broader framework, but more ambitious rationales and empirical work may be necessary for skeptical audiences. Despite ongoing theoretical debates, immediate progress can be achieved through empirical endeavors, contributing to the discipline's reputation.
The General Evolutionary Theory as Unification of Biological and Cultural Evolution and as Basis for a Natural Periodization
Authors:   JKU Johannes Kepler University Linz, Glötzl Erhard
Published: April 2024

The general evolutionary theory can be seen as a comprehensive generalization and extension of Darwin's theory. The basic idea is to consider not only the evolution of genetic information - as Darwin did - but also the evolution of very general information. It shows that evolution is characterized by the fact that new types of information have developed in leaps and bounds, each with new storage technologies, new duplication technologies and new processing technologies. This unified concept of evolution makes it possible, among other things, to 1) achieve a unified view of biological and cultural evolution; 2) find a natural periodization of the evolution from the formation of the earth until today; and 3) understand the exponential acceleration of evolution through the emergence of targeted variation mechanisms.
Chemical Evolution in Big History
Authors:   National Research University Higher School of Economics, Moscow, Grinin Leonid ,   Institute for Oriental Studies of the Russian Academy of Sciences
Published: April 2024

Unfortunately, there is insufficient research on the course of chemical evolution within the framework of the study of both Big History and evolution. The lack of attention to chemical evolution is all the more disappointing since it is a very important part of megaevolution and Big History, which at some of its stages even act as the leading line (in particular, in the formation of pre-life on the Earth five billion years ago). The paper presents a brief history of chemical evolution: from the formation of the first atoms in the Universe to abiogenesis on the Earth, that is, the stage of pre-life and the formation of prerequisites for the emergence of the first living organisms. The history of chemical evolution before life's origin can be divided into three stages: the formation of atoms (pre-evolution); history before the start of the abiogenic phase on the Earth; and abiogenic chemical evolution. However, the author aims to elaborate a more detailed periodization of chemical evolution before life's origin. One should also pay attention to the important feature of chemical evolution which distinguishes it from other lines of evolution, namely, its co-evolutionary nature. The author demonstrates that chemical evolution at all its stages acted as a part of a co-evolutionary tandem: first, as a part of cosmic and stellar-galactic evolution, then as a part of planetary evolution since it is on planets (where temperature parameters are much more comfortable for chemical reactions) that a new qualitative stage in the development of chemical evolution begins. Finally, on the Earth, it developed first as a part of geochemical evolution, and then as a part of bio-chemical evolution, and this development continues until now.
Applying a Big History Analogy to Facilitate Information Sharing
Authors: Lau Gustavo
Published: April 2024

Using analogies we generalize Tyler Volk’s combogenesis concept. A pedagogical application is a narrative that allows us to include some milestones of mathematics and physics in Big History courses. Applying the concept to books and book collections we suggest a philanthropic idea. This simple and potentially powerful application mixes low and high technology: using online bookstores, we propose the reproduction of personal book and video collections in public libraries. We give an example, at Simón Bolívar University in Venezuela, where this has already happened. We finish by proposing to use this idea to create a Big History book and video collection that could be donated to educational institutions around the world where a Big History course could be taught remotely.
An Approach to Categorize Big History Papers

There is a growing literature on Big History after seven years of the Journal of Big History (JBH) and ten years of the Evolution Almanac series. A study was done to 1) construct a reference database of these papers, which includes abstracts and many web links; 2) propose a framework to categorize these papers so that they can be filtered and searched; and 3) analyze the paper categorization to determine the statistics of frequency and topic combinations.
The Mundane in the Digital: A Qualitative Study of Social Work and Vulnerable Clients in Danish Job Centres
Authors:   , Schmidt Alexandrina
Published: April 2024

Denmark has one of the most digitalised public sectors in the world. Being a social worker within a digital public organisation requires the use of vast information and communication technologies. Being enrolled in such an organisation as a client implies being able to navigate, for example, an array of digital self-help solutions, systems such as digital ID, complete online applications, and digital mailing systems. In this increasingly ubiquitous digital society, research interests tend to overlook the mundane technologies that support and govern our everyday lives and activities. This thesis foregrounds these mundane technologies by investigating their role in social work with vulnerable clients and in vulnerable clients’ agentic practices. This thesis builds on qualitative interviews with social workers (n = 24) and vulnerable clients (n = 17) enrolled in Danish job centres. It takes a constructivist grounded theory approach to the investigation, combined with a symbolic interactionist theoretical approach. Such a combination offers systematic tools for analysis and approaches data with a focus on social interaction, context, and identity negotiations. This thesis is comprised of three articles. Article one explores social workers’ use of a digital CV tool. The study shows how social workers may collect and use information strategically through mundane technologies such as the CV tool. Article two examines the identity negotiations of vulnerable clients in response to the digital requirements of job centres. It examines how clients may reconcile contrasting demands to their positions by performing agentic vulnerability. Article three investigates social workers’ and clients’ role performances in welfare encounters via phone where non-verbal cues of interaction are absent. The study shows that phone mediation may visualise the consequentiality of welfare encounters for both social workers and clients, which may otherwise be taken for granted in routinised face-to-face encounters. Overall, the thesis demonstrates how mundane technologies partake in the social worker–client relationship. It also shows that such technologies can both enable and constrain social work practices and clients’ agentic practices and provide opportunities for everyday resistance. This thesis suggests extending the focus from new and spectacular digital technologies to the mundane in the digital.

Authors: Sánchez-Brenes Ronald , Monge-Meza Javier
Published: April 2024

Introducción: Las fincas de café con sombra son ecosistemas complejos y existe una necesidad de comprender mejor su función y servicios ambientales. Algunas de estas funciones son similares a las de los ecosistemas forestales y la biodiversidad es importante. Los mamíferos desempeñan un papel crucial en estos agroecosistemas, controlando la abundancia y composición de la vegetación, contribuyendo a la dispersión de semillas, al reciclaje de nutrientes y al mantenimiento del suelo mediante la excavación y la aireación. Objetivo: Identificar el papel de los mamíferos silvestres en la dispersión de semillas y en la cadena alimentaria en agroecosistemas cafetaleros de Costa Rica. Métodos: Trabajamos en Rincón de Mora, San Ramón, Costa Rica, desde marzo de 2019 hasta enero de 2022. Utilizamos trampas Pixestt y Havahart, y cámaras trampa, para examinar heces y comportamiento; dependiendo de la especie, el tamaño de la muestra osciló entre 2 y 87 individuos. Resultados: Identificamos 19 especies de mamíferos. Heteromys salvini tenía granos de café en sus mejillas. Echinosciurus variegatoides, Didelphis marsupialis y Philander melanurus se alimentaron de la vegetación local. Dasyprocta punctata tuvo la mayor cantidad de datos de dieta; encontramos un escarabajo en las heces de Procyon lotor y observamos un Eira barbara persiguiendo un D. punctata. Conclusión: Los agroecosistemas cafetaleros proporcionan alimento para los mamíferos silvestres, y estos contribuyen al ecosistema cafetalero como dispersores de semillas y controladores de población.

Objective To identify a diagnostic microbial signature for
endometriosis. Design Prospective cohort study Setting
Nepean Hospital and UNSW Microbiome Research Centre, St George Hospital,
Australia Population 64 age- and sex-matched subjects (
n=19 HC; n=24 N-ENDO and n=21 ENDO). All study
participants, besides healthy controls, underwent laparoscopic surgical
assessment for endometriosis, and histology was performed on excised
lesions. Methods Oral, stool, and vaginal samples were
self-collected at a single time point for healthy controls, and
pre-operatively for patients undergoing laparoscopy. Samples underwent
16S rRNA amplicon sequencing, followed by bioinformatics analysis.
Main Outcome Measures Compositional differences between cohorts
as identified by diversity analyses, and differentially abundant
microbial taxa, as identified by LEfSE analysis. Results The
composition of the oral, stool, and vaginal microbiota is different
between healthy controls and patients with and without endometriosis.
Differentially abundant taxa are present within each cohort.
Particularly , Fusobacterium was enriched in the oral samples
from patients with moderate/severe endometriosis. Conclusions
Distinct taxonomic and compositional differences were found between the
microbiota in the mouth, gut and vagina of patients with and without
endometriosis and healthy controls. Fusobacterium is noted as a
key pathogen in periodontal disease, a common comorbidity in
endometriosis. These findings support a role for the oral, vaginal, and
stool microbiome in endometriosis, and present potential for
microbial-based treatments and the design of a diagnostic swab.
A Review of Research on MnS Inclusions in High-Quality Steel
Authors: Ren Lei , Song Yan , Zhang Hainan
Published: April 2024

MnS which has good plasticity is a non-metallic inclusion commonly found
in steel. For most steel types, the size, shape, and distribution of MnS
have a significant influence on the properties of steel. The large-sized
MnS inclusions disrupt the continuity of the steel and cause the
anisotropy in steel. The result is a decline of steel’s overall
performance. In contrast, the small-sized MnS inclusions which in the
shape of spherical or spindle in steel can diminish the incidence of
thermal embrittlement and improve the machinability of steel. The
morphology of MnS in steel is mainly affected by the ingredients of
steel and heat treatment manner. MnS inclusions in steel are present in
spherical, polyhedral, dendritic, and irregular shapes. The
precipitation behavior is mainly affected by the steel ingredients, heat
treatment system and other factors. This paper summarizes the latest
research results about the factors affecting MnS inclusions and
controlling measures in high-quality steel in recent years.

Authors: Pascual-Alonso Ainhoa , Xiol Clara , Smirnov Dmitrii , Kopajtich Robert , Prokisch Holger , Armstrong Judith
Published: April 2024

MECP2 duplication syndrome (MDS) is an X-linked
neurodevelopmental disorder caused by the gain of dose of at least the
genes MECP2 and IRAK1 and is characterised by intellectual
disability (ID), developmental delay, hypotonia, epilepsy and recurrent
infections. It mainly affects males, and females can be affected or
asymptomatic carriers. Rett syndrome (RTT) is mainly triggered by loss
of function mutations in MECP2 and is a well described syndrome
that presents ID, epilepsy, lack of purposeful hand use and impaired
speech, among others. As a result of implementing omics technology,
altered biological pathways in human RTT samples have been reported, but
such molecular characterisation has not been performed in MDS patients.
We gathered human skin fibroblasts from 17 patients with MDS, 10
MECP2 duplication carrier mothers and 21 RTT patients, and
performed multi-omics (RNAseq and proteomics) analysis. Here, we provide
a thorough description and compare the shared and specific dysregulated
biological processes between the cohorts. We also highlight the genes
TMOD2, SRGAP1, COPS2, CNPY2, IGF2BP1, MOB2, VASP,
FZD7, ECSIT andKIF3B as biomarker and therapeutic target
candidates due to their implication in neuronal functions. Defining the
RNA and protein profiles has shown that our four cohorts are less alike
than expected by their shared phenotypes.
The integrative potential of contemporary perspectives on the nature/culture conceptual relationship
Authors: Knezevic Aleksandra
Published: April 2024

In this paper, I analyze and compare Maria Kronfeldner?s and Tim Ingold?s
views on the conceptual relationship between nature and culture. I show that
despite the differences, their views remain close, particularly in terms of
their integrative potential. The ultimate purpose of this examination is to
lay the groundwork for further research on the problem of conceptual
integration between sociocultural anthropology and evolutionary psychology.
The paper comprises four main sections. First, I briefly explore the history
of Darwinism to show how nature and culture were conceptualized within this
framework. Second, I deal with Kronfeldner?s separationist stance and
Ingold?s holistic perspective on the nature/ culture conceptual
relationship. Third, I discuss the implications of their views on the choice
of research heuristics in the sciences that study human nature and cultures.
While I interpret Ingold as supporting methodological integration,
Kronfelder argues for a version of integrative pluralism. Lastly, I provide
an outlook for further discussions on conceptual integration and integrative
pluralism.
Intercultural communication in contemporary art: From provocation to integration
Authors: Mitasova Svetlana
Published: April 2024

The article analyzes the forms of transmission of cultural values (meanings) through modern works of art. The novelty of the approach to artistic creation lies in it being studied both as a result of intercultural communication and as a means of conveying cultural meanings. The purpose of this article is to identify, analyze and describe the forms of transmission of values through works of contemporary art. The author identifies three forms of value translation in art: provocation, similarity, integration. Provocation means that the artist shows the interaction of the values of different cultures, focusing on their hostility and inconsistency. As an example, an art object is given by a Russian artist living in America, a representative of Sots Art A.S. Kosolapov ?Lenin - Coca-Cola.? Similarity, on the contrary, is a form that demonstrates the proximity of meanings, the search for common ground in the value systems of society. This thesis is visualized by the sculptures of Buddha and Christ by the Chinese artist Zhang Huan. The third form of translation of values in art is designated as integration, when the work expresses values that are universal for all peoples: a clean environment, security, peace, health, freedom, justice and others. The works of the winners of the Venice Biennale 2019 (opera-performance ?Sun and Sea (Marina) ? by the Lithuanian National Pavilion and ?White Album? by American cinematographer Arthur Jafa) are given as an example. It is concluded that art, thanks to its supranational, symbolic and universal language, is able to build intercultural communication between peoples.
Heat transfer performance of phase change energy storage building materials and its application in energy efficient buildings
Authors: Wang Ning , Zhou Honglei
Published: April 2024

The author proposes a phase change heat storage component combined with the
light wall interior to improve the heat storage performance. Numerical
modelling of the composite wall was performed using the finite element
program COMSOL connected to Multiphysics simulation, and its accuracy was
verified. In order to optimize the use of phase change data and the benefit
of phase change temperature, the phase change of the heating device was
carried out, and the difference in the development efficiency of the thermal
storage performance of the two types of light walls was obtained from the
ribs in the thermal phase phase exchanger compared. The results show that
the long and thin fins adjust the temperature and flow field changes of the
paraffin to the corresponding fin gap and improve the heat transfer rate,
44.8 and 26.3, respectively, the aerated concrete combined wall heat storage
and heat release time, added short ribs known need, and the connected wall
delay time is not affected by external heat. The mature thermal insulation
and thermal insulation time of the polystyrene board composite wall were
shortened by 20.8 and 52.9, respectively. Ribs are able to improve heating
efficiency and retain heat in the broken walls of polystyrene panels. The
author?s research can provide a rationale for the design and use of phase
change thermal storage.
Design and performance analysis of a heat pump system for motor phase change thermal storage
Authors: Xie Xiang
Published: April 2024

Along with the rapid economic development and social progress, the problem of
energy and environment is becoming more and more outstanding. Therefore, it
is very important to use new energy saving techniques to increase energy
consumption and reduce energy consumption. In this paper, we have developed
a hot water system, which is based on solar energy technology, gas-source
heat pump, and phase change energy storage technology. The system was
designed and constructed, and its performance was tested in various control
conditions, with an emphasis on the analysis of the influence of phase
change heat supply on heat storage properties. In this paper, the effect of
the heat storage property is analyzed. Studies have shown that compared to a
conventional tank that does not have a phase change heat storage device, the
heat storage tanks equipped with phase change energy storage devices have
longer discharge time, higher discharge temperature, better temperature, and
better operation efficiency. In addition, the data show that flow rate
control is also an important factor in optimizing the thermal storage
characteristics of the system.
Adaptive plc intelligent control based on the integrated system of smart grid thermal energy conversion
Authors: Wang Qing , Guo Chunxiang
Published: April 2024

During the construction of smart grids, due to technological limitations,
traditional sequential control systems have been unable to meet the needs
of grid operation, exposing problems such as single control methods and
functions, low operational efficiency, inability to independently complete
complex tasks, and poor anti-interference ability, which in turn affect the
power supply quality and operational stability of the grid, and fail to
truly achieve the reliability, safety, and reliability of smart grids
Economic and efficient goals. For this purpose, the author describes an
adaptive intelligent control method for an integrated biomass energy heat
conversion system consisting of more than one suction biomass gasifier,
biomass gas burner, and steam boiler. The system uses PLC as a tool and
takes the boiler outlet steam pressure as the control parameter. Based on
the changes in the boiler outlet steam pressure, it automatically adjusts
the feed and gas production of the gasifier, and subsequently adjusts the
air supply of the burner. Ultimately, it achieves the goal of automatically
adjusting the boiler heating volume with changes in steam pressure. The
integrated heating and adaptive intelligent control system based on biomass
gasification has been reliably verified in industrial applications.
Analysis of thermal characteristics of building envelope structure for night storage heating
Authors: Li Xiaodong , Liu Jianfeng , Bi Xin
Published: April 2024

In order to understand the thermal characteristics analysis of nighttime
thermal storage heating, the author proposes a study on the thermal
characteristics analysis of nighttime thermal storage heating of building
envelope structures. In some places, the writer will use an office room as a
research object. The main purpose of the experiment is to measure, compare
and analyze the surface temperature and heat flow rate of the room sample
volume under two conditions: constant power 24 hour heating and night
constant thermal power (12 hours) heating. In order to verify the accuracy
of the dynamic thermal process of the heating room, the indoor air time
variation will be performed along with the simulation results. Thermal
performance parameters and characteristics of building thermal envelope
heating effect of storage room were studied. The mathematical model of the
thermal dynamic process of the heating room was established using the heat
balance method and verified by experiments. According to the experiment,
when the heating time increases from 5-12 hours, the additional heating
consumption of the building heating system decreases by 500 Wh, and the
additional heating consumption decreases to 19.4. In addition, it is
important to change the heating time of the night-time packing model and the
total heat accumulation. In addition, external wall insulation is useful in
reducing additional heating consumption and building heating costs, but all
heat transfer between model blocks is low. As the weather changes and the
heat transfer coefficient of the external window increases, the additional
amount of heat consumption and the additional value of heat consumption for
heat storage of the building will increase. In the process of continuous
heating operation, the additional heat consumption of the building heating
system, the additional heat consumption gradually decreases, the heating
equipment changes per hour, and the total heat accumulation of the night
packing structure is important.

Published: April 2024

As a new generation of luminescent materials, aluminate rare earth materials
have the characteristics of long luminescent time, adjustable wavelength and
high brightness. Aluminate rare earth luminescent materials were prepared by
high temperature solid-state method, and the luminescent properties of the
luminescent materials were studied. Firstly, the author synthesized
magnesium aluminate, calcium aluminates, and zinc aluminate matrix by
combustion method. Then aluminate rare earth luminescent materials were
prepared by high temperature solid phase method through raw material
distribution, raw material mixing, drying, calcination, and post-treatment.
Finally, a fluorescence spectrophotometer was used to measure the excitation
and emission spectra of the prepared sample material. The research results
indicate that the excitation wavelength does not affect the relationship
between the emission wavelength and light intensity, the emission spectra
of MgAl2O4:Tb3+ and CaAl2O4:Tb3+ exhibit narrowband transition emission
states; When the mass fraction of rare earth factor Eu3+ in the activator is
6% and the temperature is 1300?C, the emission peak intensity of the
luminescent material reaches its maximum value, and the luminescence
intensity is the best.
Energy saving system for building cooling and heating integration based on building information modelling technology
Authors: Shen Xu
Published: April 2024

In order to understand the energy-saving system of building cooling and
heating integration, the author proposes a research on an energy-saving
system of building cooling and heating integration based on building
information modelling (BIM) technology. The author first analyzed the
energy-saving performance of the system by establishing models for each
module based on meteorological data simulated on the DeST software platform.
Secondly, in order to analyze the energy consumption of the integrated
system, it is necessary to establish a residential building model, and
select the building model in the cold winter and hot summer areas of a city
for analysis. The results show that due to the system?s heat storage
function, there is no need to consume electricity in spring and autumn.
Compared to the electric heating hot water mode, the integrated system can
save 1198.85 kWh of electricity in non-cooling and heating seasons, with a
100% energy-saving rate. Compared to not using an integrated system, it can
achieve an energy-saving rate of 81.9% throughout the entire refrigeration
and heating season, with significant energy-saving effects. The integrated
heating, cooling and hot water system of BIM technology adopts the
technology of cool storage and heat storage coupled with solar energy and
heat pump technology. The system has simple structure, obvious energy-saving
effect, good environmental protection, and can adapt to various climates
throughout the year. The introduction of underfloor heating also increases
the comfort of buildings and residences.

In order to understand the solar heat pump heating system, a phase-change
storage solar heat pump heating system based on cloud computing is
proposed. This paper first introduces the solar heat pump as a phase change
energy storage that can change four types of heat depending on the weather
conditions and significantly reduce the energy consumption of the system.
Second, through the special design of the energy storage capacitor, in
addition adjusting the energy distribution of the solar heat pump system, it
can also improve the reliability of supply and demand between the solar heat
pump system and the building heating system, improve the level of solar
energy consumption, but also improve the low temperature of the pump milk
temperature, and improve the solar heat up quickly to achieve the goal of
improving the overall performance of the heat pump. Finally, this paper
takes an urban ?electric coal? house as a research object to investigate the
hot air efficiency of solar heat pumps. This paper analyzes the daytime
solar heat pump mode, the nighttime energy storage mode under extreme
conditions, and the air source heat pump mode. And shows the research
results that the solar heat pump has good heating efficiency and the highest
solar COP. Will be heat pump is 5.28 solar energy average heat pump COP is
2.13. In very bad weather, solar heat pumps work better.
Numerical simulation of temperature field around buried pipes of ground source heat pumps based on mathematical models
Authors: Zhu Huiyuan
Published: April 2024

The author established a physical and mathematical model for the heat
exchange of a ground source heat pump buried heat exchanger under the
co-operation of heat and seepage, including the soil and fluid inside the
pipe surrounding the heat exchanger. Using ANSYS finite element APDL
language for programming, based on the line heat source model, simulate the
temperature field around the vertical double U-tube underground heat
exchanger, the effects of soil thermophysical properties, temperature
outside the pipe, soil type and backfill material on soil temperature field
were obtained through simulation analysis. The experimental results indicate
that, the changes in soil temperature are also significant with different
backfill materials. Therefore, it is necessary to conduct serious research
and optimization on backfill materials, develop new types of backfill
materials, improve backfill construction techniques, and conduct in-depth
research by combining theoretical analysis with practical engineering to
ultimately find efficient and economical backfill materials. The change in
equivalent pipe diameter has little effect on soil temperature, and the
linear heat source model is used for calculation without causing significant
errors. It has been proven that the soil itself has strong resilience and
has reference value for the design of buried heat exchangers in practical
engineering.

increasing power output while maintaining a constant biomass fuel and
heating volume. The EBSILON Professional software was used to model and
simulate the case unit and integrated system, and based on this,
thermodynamic characteristics such as system energy flow and energy loss
were analyzed. The results show that under design conditions, a solar power
generation capacity of 1.79 MWh can be generated, with a photoelectric
efficiency of 20.07% and a photoelectric conversion efficiency of 21.61%.
This can provide theoretical guidance for the research and practical
application of solar energy and biomass energy in integrated cogeneration
systems.
Numerical simulation and thermal analysis of ecological energy-saving ground source heat pump design

By constructing the heat transfer model of the buried tube heat exchanger,
using the mathematical method and numerical calculation software, the
temperature of the buried tube heat exchanger is calculated numerical, so as
to better understand the temperature effect of the buried tube heat
exchanger on the surrounding soil. This paper establishes a mathematical
model of a vertically buried heat transfer system based on the principle of
thermal equilibrium and the thermal conductivity differential equation.
Conduct research on the temperature field around single pipes in different
soil (geological conditions), temperature field under different drilling
backfill materials, and the temperature around buried pipelines in both
short-term and long-term operation of the system. The experimental results
show that the simulation results of the system?s short time (10 days) and
long time (90 days) performance show that the cooling and temperature cycles
in different areas directly affect the heat radius of the buried pipe and
the heat accumulation near the buried pipe. The thermal action radius of the
short-term operation system is about 1.8 m, and the long-term operation
reaches 4.5 m.

Background: Since the early 2000s, overall and site-specific cancer survival have improved substantially in the Nordic countries. We evaluated whether the improvements have been similar across countries, major cancer types, and age groups.
Material and methods: Using population-based data from the five Nordic cancer registries recorded in the NORDCAN database, we included a cohort of 1,525,854 men and 1,378,470 women diagnosed with cancer (except non-melanoma skin cancer) during 2002–2021, and followed for death until 2021. We estimated 5-year relative survival (RS) in 5-year calendar periods, and percentage points (pp) differences in 5-year RS from 2002–2006 until 2017–2021. Separate analyses were performed for eight cancer sites (i.e. colorectum, pancreas, lung, breast, cervix uteri, kidney, prostate, and melanoma of skin).
Results: Five-year RS improved across nearly all cancer sites in all countries (except Iceland), with absolute differences across age groups ranging from 1 to 21 pp (all cancer sites), 2 to 20 pp (colorectum), -1 to 36 pp (pancreas), 2 to 28 pp (lung), 0 to 9 pp (breast), -11 to 26 pp (cervix uteri), 2 to 44 pp (kidney), -2 to 23 pp (prostate) and -3 to 30 pp (skin melanoma). The oldest patients (80–89 years) exhibited lower survival across all countries and sites, although with varying improvements over time.
Interpretation: Nordic cancer patients have generally experienced substantial improvements in cancer survival during the last two decades, including major cancer sites and age groups. Although survival has improved over time, older patients remain at a lower cancer survival compared to younger patients.

Durante el crecimiento y desarrollo de los niños, pueden surgir cuestiones ortopédicas que generen dudas tanto en las familias como en los pediatras, en términos de si representan variantes normales o patologías que deben ser observadas o tratadas de manera conservadora o quirúrgica., En este artículo, se mencionaran las condiciones que se consideran que generan la mayor cantidad de consultas en la práctica diaria de la ortopedia infantil, además se mencionaran enfáticamente las patologías más redundantes en nuestro medio como son el genu valgo mismo que se define como una deformidad caracterizada por una desviación de la pierna hacia fuera respecto al muslo, y genu varo que se define como un arqueamiento de las rodillas hacia afuera, se analizaran los diagnósticos, y los tratamientos sugeridos para su corrección.
Students’ Constructions of Professional Judgement in Teacher Education, Medical Education and Police Education

Published: April 2024

Professional higher education encompasses the development of relational skills and professional judgement, especially in welfare professions where close contact with people is essential, such as policing, teaching and health care. In the current article, using a cross-professional analysis, we explore how students from three different professional education programmes – teacher education, police education and medical education – construct professional judgement in group discussions and interviews. The results show that participants construct professional judgement as a relationship between three different dimensions: personal ethics, educational standards and professional practice. The examples in this article show how students utilise these three different dimensions when discussing professional dilemmas to account for choices that they (would) make as being morally or ethically sound. We argue that these results shed light on the importance of providing students with opportunities to reflect openly on professional judgement in different ways, even though this may not currently be examined or graded in their education. Furthermore, the analysis demonstrates similarities between the three examined programmes, as well as similar student reflections on essential aspects of the professions.

Published: April 2024

Este artigo tem como objetivo apresentar uma experiência cocriada com os discentes de Pedagogia da Universidade Federal de Sergipe sobre fake news, pós-verdade e vigilância nas redes com um olhar para as performances (des)informais atravessadas no cenário político, econômico e social no Brasil. Para tanto, as aulas foram pautadas no referencial abordado nesse estudo, dentre alguns deles estão: Bonilla (1999), Castells (1999), Freire (1999), Lévy (1993), Lucena e Oliveira (2014),  Pretto (1996), Primo (2007), Santaella (2018), Silveira (2017) etc. De modo geral, os resultados mostraram que os discentes possuíam os dispositivos móveis digitais, mas desconheciam o processo de disseminação de notícias falsas, por isso, as aulas sobre esse conteúdo foram uma oportunidade de conscientizar formas de fazer a educação crítica voltada para o combate das ambivalências manifestadas no digital em rede.
