Published: October 2022

Desert wetland is a special ecological environment as water is fundamental to maintaining existence. The soil water of sandy wetland links surficial water and groundwater. This study Takes Habahu National Wetland Nature Reserve as the research area and the water movement characteristics of soil profile as the research purpose. According to the altitude and topographic characteristics, the main focus is monitoring soil moisture in different layers at specific sites. The results show that: (1) In the core area of sandy wetland, the water movement of the soil profile is slow with lower infiltration and evaporation; (2) On the slopes around the wetland, the surface water is recharged by rapid leakage along with the underlying impermeable layer after precipitation due to the sand coverage; (3) In the desert hinterland outside the wetland, the water rapidly infiltrates after precipitation and flows into different groundwater systems along the structural characteristics of the underlying stratum to supplement the nearby wetlands. Based on these characteristics, we put forward the unique viewpoints of environmental protection in sandy wetlands: (1) focus on the protection of surface organisms in the core area of sandy wetland to reduce evaporation and improvethe soil water-holding capacity; (2) Appropriate engineering and biological measures should be applied to the slope outside the core area to reduce surface evaporation and plant transpiration and improve the soil moisture; (3) In the periphery area of the wetland, infiltration should be promoted to ensure the source of water supply to wetlands, which would maintain the existence of wetlands and give full play to their ecological functions. In addition, this study analyzed the relationship between soil moisture and plant diversity of 35 species. 16 plants are considered to be suitable for planting in core area of sandy wetland and 9 plants for planting in the desert hinterland outside the wetland.

Authors: Martínez-Hernández M.D.J. , Torres-Pelayo V.R. , Castillo-Rocha D. G.
Published: October 2022

Veracruz State has been described as one of the richest states in Mexico, in terms of its medicinal herbal diversity at a local and regional level, and its culture of utilization of such resources in traditional medicine. These resources are valued by their cultural and economic importance and by their usage in the healthcare system. In this study, we explore the value of Mexican traditional medicine knowledge registered in literature on this subject-books, thesis, and publications in ethnobotany scientific journals- from different localities in Veracruz State. We have found reports of a wide variety of plants used to heal different sufferings such as: cough, pain, healing, inflammation, gastrointestinal problems, cancer and diabetes of people who live in communities of Huasteca and Totonaca regions, Nautla, Capital or Central, Mountains, Los Tuxtlas and Olmeca in Veracruz, Mexico. The wide variety of plants found shows us a general scene of Veracruz State’s great cultural richness. Some species commonly reported are Bursera simaruba, Tithonia diversifolia, Oenthera rosea, Bidens pilosa, Heterotheca inulodes. The formulations are tea, infusion, cataplasm or washings of the whole plant, root, blossom, bark, stem, leaves or fruits; they are essential to heal each attended illness by people in their communities. This review show that the traditional use of medicinal plants are of great importance due to their healing properties and contributes to an understanding of their biological activity. Furthermore, it will necessary to conduct further researches to evaluate these plants’ effectiveness and safety, and to identify the compounds involved in them.

Globalization: Managing Cross-Cultural Diversity in Finance
Authors: Rai Dr. Supriya
Published: October 2022

Abstract: One notices an emerging trend among companies with global operations to seek culturally competent employees. Global competitive environments dictate the need for dynamic managerial capabilities relevant to multicultural working environments that will give an employer the much needed competitive edge over rival companies. Managers, including finance managers need the ability to negotiate and work within two or more cultures with equal ease in a multicultural environment. Managers with tactic cultural knowledge and competencies are pivotal to the global expansion plans of any company. Universities are taking up the task of creating internshipopportunities that offer such multicultural experiences to their students. This paper is based on the author’s learning experience and personal reflection of an internship in Vietnam analyzed through a lens of Australian university and had the opportunity to work with Vietnam’s largest insurance company (and seventh largest by market capitalization).
To Investigate the Mechanical Properties of Concrete by Partial Replacement of Cement with Ceramic Tiles Waste Powder and Addition of Jute Fiber
Authors: Sundhan Shanti Saroop , Sharma Sucharu
Published: October 2022

Abstract: The need for natural and non-renewable resources has grown as a result of the continuing development of society and human endeavours. As a result, the amount of industrial solid waste products kept growing. The most widely used man-made material in the world, concrete, has generated a lot of interest as a potential method for recycling solid waste. About the same amount of CO2 is produced during the manufacture of 1 tonne of Portland cement. The cement sector is thought to be responsible for 5% to 8% of yearly global greenhouse gas emissions. The use of waste materials in our current concrete can lessen the environmental pollution. Put the scenario in a critical state employing alternate approaches and come up with a better material recycling solution. As additional cementitious materials, a variety of by-products, including fly ash, slag, and silica fume, are successfully used every day in the manufacturing of concrete (SCM). According to the research it has been found that about 150 million tons of ceramic have been produced per year. From that total production, around 25% to 35% has become waste material without recycling from the ceramic industry at present. The ceramic powder has various advantages such as cost - saving, energy Saving and reduces the hazards materials to the environment. Ceramic waste can be used in concrete to increase the compressive strength and physical and chemical properties of concrete. It has been established that the addition of evenly distributed, tightly spaced Fibers to concrete will significantly enhance its static and dynamic properties and act as a crack arrester. Concrete that has been reinforced with fibrous material, or fiber-reinforced concrete (FRC), has a higher structural stability. It is important to note that jute is sometimes referred to as the golden fibre owing to its high cash value and its colour. It improves the shear and punching resistance of concrete, aid in recovering post-cracking strength losses, increases the toughness and become an effective way for reinforcement. In this experimental work, partial replacement of cement by ceramic tiles waste powder by percentages of 0%, 15%, 20%, 25% and 30% with expansion of Jute Fiber at different rate as 0%, 0.25%, 0.50%, 0.75% and 1.0% are done to make sustainable concrete. All specimens were cured for 7days and 28 days before testing. From the study it has been observed that the test results shows optimum proportion for concrete mix and are within acceptable limits.
Use of Green Concrete in a REGID Pavement: A Review
Authors: Sharma Gagan , Chaudhary Harivansh Kumar , Malik Akash
Published: October 2022

Abstract: Eco-friendly wastes are being used to make green concrete. It minimizes Carbon footprints while causing the lowest environmental damage. It saves up to 20percent of total on water demand. The down on carbon footprints by 40-50 percent throughout the manufacturing process, the increase in construction activity in underdeveloped nations, and the use of lesser water are the principal factors boosting the green concrete market. Still though, it provides a significant degree of fireproofing and good thermal insulation, allowing green concrete to be used in structures. Green asphalt can be made from a variety of plastic waste. The use of waste materials and admixtures to partially replace substances results in increased compressive strength and split tensile, corrosion conductivity, porosity reduction, and improved flowability.

Since its first discovery in the nineteenth century, polymer researchers have continued to study poly(vinyl chloride). Its characteristics, such as its thermal instability, are delicate by its structural flaws that result from its containing chlorine atom which is sensitive to UV light as a good leaving group. Many researchers suggested adding various types of organic and inorganic additives as photo and/or thermal stabilizers of poly(vinyl chloride). Recently this work has been expanded by extensive ongoing research to modify the chemical structure of poly(vinyl chloride) by replacing part of the chlorine atoms with other molecules which could enhance its stability against weathering circumstances. The last was carried out not only for common chemical reactions but also to improve the characteristics of poly(vinyl chloride) in particular applications. Basedon reports from the past ten years, this study outlines many of the chemical alterations of poly(vinyl chloride) as well as associated uses. These alterations are organized following the modification of poly(vinyl chloride) through Carbon-Carbon and Carbon-Nitrogen linkages.

Published: October 2022

One of the important applications that organize people's lives is the applications that relate to organizing the traffic regulation, detecting violators, detecting stolen cars, and managing car parks. Recognizing the license plate number (LPN) crosses the basic process in all previous applications. This process is affected by the surrounding light conditions while taking an image of the car. In addition to these problems, the plates of modern Iraqi cars (the so-called German number) suffer from words in silver color printed on the plate, which causes a senior problem when locating the LPN and recognizing it. To solve these problems, we presented in this research a comparison between the use of the SIFT and Contour algorithm in locating the LPN. While using CNN training models to recognize the PN achieved higher results than template matching.
Reflections From Family Medicine Residents on Training During the COVID-19 Pandemic
Authors: Staloff Jonathan , Jabbarpour Yalda
Published: October 2022

Background and Objectives: Given their broad scope of training, family medicine residents were uniquely situated to care for the American public throughout the COVID-19 pandemic, yet little has been written about their experiences. The objective of this report is to capture the diversity of experiences and contributions of family medicine residents across the United States to the care of the American public during the COVID-19 pandemic.
Methods: Investigators recruited resident interviewees from four residencies throughout the United States via convenience sample. These residencies represented a diversity of geography, rurality, and structure (hospital based vs community based). Investigators conducted 30 to 60-minute, semistructured interviews with family medicine residents. Interviews were recorded and examined for themes.
Results: Three major themes emerged through the interview process. First, family medicine residents were a critical component of the inpatient response to COVID-19 in a variety of geographies from urban centers to rural towns to Native American reservations. Second, family medicine residents continued to provide expanded outpatient care to include telehealth, immunization clinics, and public health campaigns to meet the needs of the community. Finally, not only did these residents have an immense impact in the response to COVID-19, but the pandemic also had an immense impact on them, both personally and professionally.
Conclusions: The story of family medicine contributions to the care of the public during COVID-19 reflects the history of COVID-19 in the United States, and the critical role trainees and family medicine physicians have in the US health care system.

Authors: Chaverri Carlos , Ramón-Farías Feliza , Cicció José F.
Published: October 2022

ABSTRACT: Introduction: Lippia is a Verbenaceous genus of flowering plants, which has about 200 species, distributed throughout the southern USA, Mexico, and Central America to South America. Objective: To study and compare the chemical compositions of the essential oils of L. alba growing in Mexico and Costa Rica. Methods: The essential oils were obtained by hydrodistillation in a Clevenger-type apparatus. The chemical composition of the oils was analyzed by capillary GC-FID and GC-MS using the retention indices on a DB-5 type capillary column in addition to mass spectral fragmentation patterns. Results: A total of 65 compounds were identified in the essential oil samples from both countries, accounting for 96,5-98,1% of the total amount of the oils. The main constituents of the Mexican sample were 1,8-cineole (22,3%), myrcenone (11,2%), myrcene (10,9%), (E)-ocimenone (10,7%), (Z)-ocimenone (7,5%), and sabinene (6,8%), while for essential oil from Costa Rica the major compounds were myrcenone (30,4%), 1,8-cineole (21,4%), myrcene (11,0%), hedycaryol (4,4%), and sabinene (4,3%). Samples from both countries can be classified as belonging to chemotype “tagetenone”. Lippia alba (strong form) from Costa Rica produces essential oil that differs from all other essential oils of L. alba studied to date because it contained the sesquiterpenoids hedycaryol and the isomeric alcohols α-eudesmol, β-eudesmol, and γ-eudesmol. Conclusion: L. alba (strong form) from Costa Rica can be classified as a new subtype of the chemotype “tagetenone” (chemotype II).

Published: October 2022

The current study aims to examine the relationship between the delegation of authority and employee performance in the banking sector in Palestine. Delegating authority explores new competencies and experiences that increase the quantity and quality of performance (Al-Jammal, Al-Khasawneh, & Hamadat, 2015). The concept of delegation of authority is gaining increasing attention by human resources management in large organizations because the concept of delegation of authority is one of the most important concepts used in the practice of management (Muhammad & Kazmi, 2020). A questionnaire was used to collect data and 300 questionnaires were distributed after being reviewed by a panel of experts. The Social Package for the Social Sciences (SPSS) was used to analyze and process the data, and the study found that there is a positive relationship between the delegation of authority and performance. This relationship mediates job satisfaction, as delegation contributes to increased job satisfaction, thus, job satisfaction increases the quality of performance. The current research recommended that additional efforts should be invested to enhance the culture of delegation of power and attention to the state of job satisfaction among workers in banks as well as other institutions and that future research should focus on finding new ways to ensure improvement in the quality of performance in the banking sector in Palestine
Facing economic and business complexity: An analysis of the evolving features of the board of directors’ meetings in Italy

Published: October 2022

This study analyzes how corporate governance practices evolve to keep up with external complexities. The analysis is carried out on all Italian listed companies in the period 2018–2020. The findings suggest that Committees of the Board of Directors increased in number during the period, and the frequency of their meetings also increased. There was little variation in the frequency of the Board of Directors’ (BoD) meetings. The paper provides empirical evidence on the current trend for establishing smaller working parties that do not burden the whole BoD when the firm faces issues for which specialized skills and greater attention are required. Our study contributes to previous literature on corporate governance by jointly analyzing different mechanisms of BoD. Moreover, to the best of our knowledge, it explores for the first time the duration of the meetings of the BoD and its Committees.

Background and aims: Transvenous lead extraction (TLE) has
become a pivotal part of a comprehensive lead management strategy,
dealing with a continuously increasing demand. Nonetheless, literature
about the long-term impact of TLE on survivals still lacking. Given
these knowledge gaps, the aim of our study was to analyse very long-term
mortality in patients undergoing TLE in public health perspective.
Methods: This prospective, single-centre, observational study
enrolled consecutive patients with cardiac implantable electronic device
(CIED) who underwent TLE, from January 2005 to January 2021. The main
goal was to establish the independent predictors of very long-term
mortality after TLE. We also aimed at assessing procedural and
hospitalization related costs. Results: We enrolled 435
patients (mean age 70 ± 12 years, with mean lead dwelling time 6.8 ±
16.7 years), with prevalent infective indication to TLE (92%). Initial
success of TLE was achieved in 98% of population. After a median
follow-up of 4.5 years (range 1 month- 15.5 years),150 of the
435enrolled patients (34%) died. At multivariate analysis, death was
predicted by: age (≥ 77 years, OR: 2.55, CI: 1.8-3.6,
p<0.001), chronic kidney disease (CKD)defined as severe
reduction of estimated glomerular filtration rate (eGFR <30
mL/min/1.73m2, OR:1.75, CI: 1.24-2.4, p=0.001), systolic dysfunction
assessed before TLE defined as left ventricular ejection fraction (LVEF)
<40%, OR:1.78, CI 1.26-2.5, p=0.001). Mean extraction and
reimplantation-related costs were \euro5989 per
procedure. Conclusions: Our study identified three predictors
of long-term mortality in a high-risk cohort of patients with a cardiac
device infection, undergoing successful TLE. The future development of a
mortality risk score before might impact on public health strategy.

1. Understanding animals’ selection of microhabitats is important in
both ecology and biodiversity conservation. However, there is no
generally accepted methodology for the characterisation of
microhabitats, especially for vegetation structure. 2. Here we present a
method that objectively characterises vegetation structure by using
automated processing of images taken of the vegetation against a
whiteboard under standardised conditions. We developed an R script for
automatic calculation of four vegetation structure variables derived
from raster data stored in the images: leaf area (LA), height of closed
vegetation (HCV), maximum height of vegetation (MHC), and foliage height
diversity (FHD). 3. We demonstrate the applicability of this method by
testing the influence of vegetation structure on the occurrence of three
viperid snakes in three grassland ecosystems: Vipera graeca in mountain
meadows in Albania, V. renardi in loess steppes in Ukraine and V.
ursinii in sand grasslands in Hungary. 4. We found that the variables
followed normal distribution and there was minimal correlation between
those. Generalized linear mixed models revealed that snake occurrence
was positively related to HCV in V. graeca, to LA in V. renardi and to
LA and MHC in V. ursinii, and negatively to FHD in V. renardi, and to
HCV in V. ursinii. 5. Our results demonstrate that biologically
meaningful vegetation structure variables can be derived from automated
image processing. Our method minimises the risk of subjectivity in
measuring vegetation structure, allows upscaling if neighbouring pixels
are combined, and is suitable for comparison of or extrapolation across
different grasslands, vegetation types or ecosystems.

Published: October 2022

Objective: To analyse the impact of parity on pelvic floor morphology
and function in postpartum period. Design: Retrospective study Setting:
single-country . Population: This study included 1076 participants who
visited Fujian Maternity and Child Health Hospital from December 2019 to
August 2022. Methods: One-way ANOVA and covariance analysis were used
between groups. Pearson correlation analysis and partial correlation
analysis were used to assess the relationship between variables. Main
outcome measures: Modified Oxford scale, surface electromyography, and
pelvic floor three dimensions ultrasound. Results: Both one-way ANOVA
analysis and covariance analysis indicated that the differences between
primipara, deuteripara, and tertipara in bladder neck presentation,
urethral rotation angle, bladder neck descent, and hiatal area were
statistically significant. Pearson and partial correlation analysis all
showed the positive correlations between rapid contraction, tonic
contraction, endurance contraction and the grade of modified Oxford
scale. Unlike pearson correlation analysis, most correlations subsided
in the further partial correlation analysis except pretest resting
baseline with urethral rotation angle. Conclusion: The grade of modified
Oxford scale exhibited a positively correlation with the contractions of
surface electromyography which reflected the reliability of pelvic floor
surface electromyography. The impact of parity on not only the grade of
modified Oxford scale but also surface electromyography was not
statistically significant, but the descent of pelvic organ increased as
parity increased. Except pretest resting baseline, any other factors of
modified Oxford scale and surface electromyography had no correlation
with pelvic organ displacement.

Published: October 2022

Objective(s): Trainee assessments aim to identify areas for
improvement and address problems within training programs. However,
effectiveness is limited by an inability to assess programs anonymously.
We hypothesized concern for undesired repercussions may discourage
honest responses. To test this, we conducted a comprehensive survey of
trainees to assess their educational and work-related experiences
anonymously.  Design: A 51-question survey was distributed
electronically to the Thoracic Surgery Residents Association (TSRA)
membership. Questions were multiple-choice. The Likert scale was
utilized.  Setting: The survey was accessed electronically and
was completed by participants nationwide. Participants:
Trainees were incentivized to complete the survey with the opportunity
to receive a $50 gift card or TSRA textbook. 109 of 551 cardiothoracic
surgery trainees completed the survey. Results: 109 trainees
(109/551, 19.8%) completed the survey. 57.8% of respondents reported
complying with work hour restrictions, but 32.2% (n=35) did not feel
comfortable reporting violations honestly. The majority of respondents
agreed or strongly agreed that their program was preparing them to
independently perform low risk cardiac (4.19 [1.22]) and thoracic
(4.08 [1.13]) cases independently, 30.3% of chief residents
reported planning to pursue additional training. 66% of respondents
stated they would select the same program again. 33% reported having
high morale, 47.7% moderate and 19.3% poor or declining morale. 84.4%
of respondents did not feel their race or gender significantly impacted
their training, 26.6% reported systemic bias in recruitment of new
trainees or faculty, and 38.5% believed there was inadequate diversity
among faculty and trainees. 30.3% reported experiencing verbal or
physical harassment by an attending or fellow (14.7%). 
Conclusions: Despite reporting an overall positive operative
experience, a significant number of trainees plan to pursue additional
training. The survey identifies important areas for attention including
underreporting of issues related to diversity, as well as verbal and
physical harassment by fellows and attendings.
Diversity of haemoparasites in transhumant small ruminants of Himalayas, India

Published: October 2022

Transhumant migratory sheep and goats of Himalayas were molecularly
screened for various haemoparasites like Anaplasma/Ehrlichia,
Theileria/Babesia, Babesia spp., Theileria spp.,
Anaplasma marginale, Theileria luwenshuni, Theileria
orientalis and Trypanosoma evansi using their specific primers.
Out of the 171 animals screened, 73.09% of the animals were infected
with Anaplasma spp. and 74.85% of the animals with
Theileria spp., while no animals were found infected with
Babesia spp. and Trypanosoma evansi. In a quest to
identify the species, few positive PCR amplicons representing
Anaplasma spp., Theileria spp. and
Theileria/Babesia spp. were sequenced. The sequences obtained
were further BLAST analysed to reveal maximum identity with
Anaplasma capra (100%), Theileria luwenshuni (99.71%)
and Theileria sinensis (98.73%). Among them Theileria
luwenshuni was further confirmed with their species-specific PCR and
the positive amplicons were sequenced and BLAST analysed to reveal their
maximum identity with Chinese isolates rather than Indian isolates.
Further, phylogenetic analyses of the resulting sequences were conducted
to identify their evolutionary history. It revealed that 1100 bp -
amplicons of Theileria spp. were showing maximum identity to
Theileria sp. MK, a non-transforming Theileria. This is
the first report of zoonotic Anaplasma capra and Theileria
sp. MK in small ruminants from India and it could be mostly due to their
transboundary migration history through Indo-Tibetan border during
summer seasons as a part of traditional migratory system of livestock
rearing practice in Himalayas. The high prevalence of haemoparasites in
migratory small ruminants call for adoption of effective control

Background: Music therapy (MT) is a complementary therapy
offered to children, young adults and their families in pediatric
oncology and palliative care. We performed a survey to collect
information about MT in pediatric oncology in Italy. The outbreak of
COVID-19 unavoidably changed the scenario of MT, suggesting some
considerations presented in this survey. Methods: 27/32
(84,4%) Centres belonging to the Italian Association of Pediatric
Hematology and Oncology (AEIOP) completed in 2 different time points (T1
and T2) an online survey on MT, before and after Covid-19 pandemia.
Results: Different kinds of music approach were used taking
care of patients in 21/27 centers, while in 14/21 (66%) a specific
project of MT conducted by a music therapist was present. In 6/14
Centres MT activities were delivered for <3 hours/week, in 3
Centres for >3 and <10 hours/week, in the
remaining 5 for >3 hours/week. MT sessions were in
different areas, day hospital or ward (patient rooms, operating rooms,
waiting rooms), on an individual basis or by groups. Patients were
invited to MT by psychologists, caring physician or nurse, or on equipé
decision. MT was evaluated with tools self-made by Music therapist in
11/14 centres. After Covid-19. MT has been withdrawal in 3 centres,
sessions in the waiting rooms were reduced, individual sessions were
preferred and enrollment by multidisciplinary teams increased.
Conclusion: This survey represents the starting platform to
compare and discuss different experience of MT in AIEOP Centres, to
implement MT in pediatric oncology for a more qualified assistance to
patients and to improve quality of care.

Published: October 2022

Trunk neural crest cells (TNCC) are representing a model for epithelial
to mesenchymal transition, this correlates the importance of studying
the migration of these cells to cancer metastasis. Reptiles are unique
group of animals being very morphologically diverse and their close
position to synapsid leading to mammals. Recently, more publications
focused on the migratory behavior of trunk NCC during embryonic
development of squamates. Only one colubrid snake has been studied so
far regarding the NCC migration. Here we follow the migratory behavior
of TNCC with HNK1 in the elapid snake Naja h. haje from early stage to
16-20 days postoviposition. Our findings show: First, comparing the
colubrid snake with the Egyptian cobra shows that both snakes overall
follow the conserved TNCC migratory pathways of both birds and mammals
by following the rostral and avoiding the caudal portions of the
somites. Second, TNCC intra-somitic migration suggests that cobra TNCC
could contribute to snake scale formation analogously to turtle shell.
Third, the presence of MITF in Schwann cell precursors along developing
nerves, which suggests that reptile Schwann cell precursors could have
the same multipotency as mammalian migrating NCC and thus give rise to
its varied derivatives. Our present results of the Egyptian cobra in
combination with those on a colubrid and turtle supports intersomitic
TNCC as a unique reptile phenomena.
Impact of Corona pandemic on operations and supply chain of Agriculture and Food Processing Sector with reference to MSME in India and the expected recovery prospect
Authors: Baisya Rajat K
Published: October 2022

This article attempts to assess the impact of Corona pandemic on businesses with particular reference to Agriculture and Food processing industries in MSME sector in India and tracing the possible recovery in terms of recreating the lost demand in domestic as well as in international markets. The industries were caught unaware to face the challenges of disruption with sudden announcement of lockdown and the resulting consequences. Industries in MSME sector depends on the functioning of large processors as their support and contract manufacturers as well as on their limited market opportunities which they have developed. During pandemic both collapsed. With the drastic reduction in consumption expenditure and disruption in supply chain coupled with the severe cash crunch, MSME sector has suffered the most. While the impact of COVID-19 on food and agricultural sector was less when compared with other sectors but even in this sector for MSME it was devastating. This article attempts to trace the reasons and estimating the magnitude of the impact and the possible way forward.

A quarter of the world’s population is estimated to meet the criteria for metabolic syndrome, a cluster of cardiometabolic risk factors that promote development of coronary artery disease and type II diabetes, leading to increased risk of premature death and significant health costs. In this study we investigate whether the genetics associated with metabolic syndrome components mirror their phenotypic clustering. A multivariate approach that leverages genetic correlations between fasting glucose, high-density lipoprotein cholesterol, systolic blood pressure, triglycerides, and waist circumference was used; which revealed that these genetic correlations are best captured by a genetic one factor model. The common genetic factor genome-wide association study (GWAS) detects 235 associated loci, 174 more than the largest GWAS on metabolic syndrome to date. Of these loci, 53 (22.5%) overlap with loci identified for two or more metabolic syndrome components, indicating that metabolic syndrome is a complex, heterogeneous disorder. Associated loci harbour genes that show increased expression in the brain, especially in GABAergic and dopaminergic neurons. A polygenic risk score drafted from the metabolic syndrome factor GWAS predicts 5.9% of the variance in metabolic syndrome. These results provide mechanistic insights in the genetics of metabolic syndrome and suggestions for drug targets, especially fenofibrate, which has the promise of tackling multiple metabolic syndrome components.

Authors: Raggio Sandra , Garcia Roberto Cipriano
Published: October 2022

En este trabajo se presentan las principales líneas de acción del organismo público argentino, la Comisión Provincial por la Memoria, con las organizaciones de familiares de víctimas de la tortura y otras violencias estatales ocurridas en la democracia post dictadura, en particular a aquellas ligadas con el sistema de penitenciario y las fuerzas de seguridad. Se analiza la relación entre estos colectivos y las organizaciones históricas de derechos humanos nacidas durante la dictadura militar, el rol de las madres que reclaman por la vida de sus hijos e hijas y la filiación de sangre como credencial de legitimación social y política de estas nuevas actoras.
Miről árulkodnak a szállított ásványszemcsék mikromorfológiai bélyegei?

Published: October 2022

A homokszemcsék mikromorfológiájának vizsgálatával már közel egy évszázada foglalkoznak a kutatók, már akkor felfigyeltek néhány összefüggésre a szemcsék felszínén megfigyelhető formák, valamint a geológiai környezet között. Az általunk bemutatott módszer jelentősége abban rejlik, hogy ideális esetben a bélyegekből és azok együtteseiből valószínűsíteni lehet a szállítási móddal kapcsolatos különböző környezeti tényezőket és időbeli változásukat, sőt akár következtethetünk a forrásterület korábbi éghajlatára is. Folyamatosan fejlődő módszerről van szó, ezért fontos megjegyeznünk, hogy az általa tehető megállapítások még nem tekinthetők olyan biztosnak, mint a nála elterjedtebb, gyakrabban alkalmazott paleokörnyezet-határozásra használt eljárások. Munkánk célja, hogy bemutassuk ezt a törmelékes szedimentológiában alkalmazható, eddig főleg hazánkban kevéssé ismert és elterjedt vizsgálati módszert, amelynek pontosan emiatt nincsen hivatalosan bevezetett és elfogadott magyar nevezéktana. Ebből kifolyólag úttörő munkának számít hazánk tudományos életében, célunk az eredeti angol nevezéktanból kiinduló, magyar nyelvű szakkifejezések bevezetése.A módszerben sok új lehetőség rejlik (pl. statisztikai megközelítés fejlesztése, morfológiai jegyek együttes jelenlétének értelmezése), a téma pedig nemzetközi szinten is egyre népszerűbb. Korunk egyik legnagyobb környezeti kihívása a klímaváltozás. Folyamatainak minél pontosabb megismeréséhez és megértéséhez ismernünk kell ezek múltbéli megfelelőit. Erre már számos módszer létezik (pl. dendrokronológia, jégfuratok izotópösszetételének vizsgálata), ugyanakkor az üledékes szemcsék vizsgálata további értékes, új információt nyújthat a témában.
A Battonya–Pusztaföldvári-hát térségének nagy entalpiájú geotermikus energia vagyona (II. rész): kútpárral történő hasznosítás UNFC-2009 kód szerinti osztályozása

Published: October 2022

Tanulmányunk első részében (Kun et al. 2022) bemutattuk a Battonya–Pusztaföldvári-hát repedezett preneogén-prekainozoos aljzatának földtani, hidrogeológiai adottságait és a geotermikus energia hasznosítását célzó hidrodinamikai és hőtranszport modelljét. Jelen tanulmányban, az említett félszintetikus, ekviporózus modell segítségével, kiszámítottuk az egy kútpárral (doublet) kitermelhető hő mennyiségét több forgatókönyv szerint, a technológiai korlátokat szemelőt tartva. A számítások során az Egyesült Nemzetek Európai Gazdasági Tanácsa által kidolgozott UNFC-2009 kód nevű osztályozási keretrendszert alkalmaztuk (UNECE 2016a). Az adatokban rejlő bizonytalanságot Monte Carlo szimulációval vettük figyelembe, majd az így létrejött paraméter-tartományokból fuzzy számokat képezve alkottuk meg a modellek bemenő adatait. Ezt követően a FEFLOW® véges elemes modellező szoftverrel kapott kitermelhető geotermikus készlet adatokat összevetettük a statikus módon számolt értékekkel. A két számítás között fél nagyságrend eltérést kaptunk a modellezett értékek javára, mely véleményünk szerint jobban tükrözi a várható értékeket, mint a statikus készletszámítás eredménye. A Battonya–Pusztaföldvári-hát jelen tanulmányban feltételezett projektjének UNFC-2009 kód szerinti geotermikus készlet osztálya: E3.2, F3.3 és G4. A vizsgálatsorozat alapján megállapítottuk, hogy egy lehatárolt térfogatú, közel zártnak tekinthető rezervoár optimálisan elhelyezett termelő-visszasajtoló kútpárok esetén is hamar kimerülhet (akár 20–30 év alatt), ha nem tud rácsatlakozni egy nagyobb, folyamatos hőszállítást biztosító rendszerre, mint amilyenek a neotektonikai mozgásokkal felnyíló, mélységi vetőrendszerek. Vizsgálatunknak nem volt része a geotermikus fluidum összetételéből adódó kihívások számbavétele, valamint a szűrőberendezés és a kútkörnyezet időben változó folyamatainak elemzése (geokémiai, szerkezeti stb.), de tudatában vagyunk, hogy ezek mind kritikus tényezők lehetnek egy nagy entalpiájú geotermikus kútpár fenntartható üzemeltetésekor. Úgy véljük, tanulmányunk hasznosan járul hozzá a geotermikus kutatás és energiahasznosítás valós kockázatainak számszerű jellemzéséhez, segítve a projektek gazdasági szempontú tervezését is.
