Impact of elevated CO2 on high temperature induced effects in grain yield of chickpea (Cicer arietinum)
Authors: RAI PUJA , CHATURVEDI ASHISH K , SHAH DIVYA , PAL MADAN
Published: July 2023

High temperature and increasing atmospheric CO2 are debatable issues under climate variability and of major concern for agricultural productivity. Field experiments were conducted with two chickpea (Cicer arietinum L.) genotypes, viz. Pusa 1103 (desi) and Pusa 1105 (kabuli) to examine the role of elevated CO2 (570±86 µmol/mol) and high temperature (5.93±0.22ºC above ambient) on yield and biomass using Open top chambers and temperature tunnel respectively. Elevated CO2 enhanced the grain yield and biomass of both the chickpea genotypes by 34-47 and 39-55 percent respectively while, high temperature exposure reduced the yield of both the genotypes by 19-30 percent. Among genotypes, counter effect of CO2 to high temperature is more prominent in desi compared to kabuli which was attributed with more partitioning of assimilates toward pods in desi. While in kabuli genotypes the biomass partitioning was more towards vegetative plant parts attributing enhanced biomass. Study concludes that elevated CO2 could ameliorate the reductions in yield under high temperature by more dry matter partitioning towards pods instead of temperature induced partitioning towards vegetative plant parts.

Published: July 2023

Sandwich composites have been used as lightweight materials in aircraft manufacturing for a long time, from balsa wood sandwich in the 1930s to honeycomb and fiber-reinforced polymers sandwich. Its characteristics are considered as a 'perfect' material for aircraft, which has high strength with low density. Sandwich composites are the common materials for aircraft floor panels. The core is usually made of Nomex or aluminum honeycomb, while the skin is made of 1 "“ 2 ply of carbon/glass fiber in epoxy resin composite. The core is usually constructed using the corrugating or expansion method, whilst the skins are usually constructed using the prepreg lay-up method. Both materials are combined together by a simple adhesive bonding. Being the most strictly regulated transportation method on the planet, floor panel manufacturers must abide by aircraft manufacturing companies and local aviation authority standards and specifications to ensure the product's safety. The purpose of this study is to determine the most used materials for aircraft floor panels and why is it widely used, to understand the manufacturing process, and to know the specifications and standards that need to be fulfilled.
Problematizations about distance education in contemporaneity from the Heideggerian perspective: Beyond the debate on distances and proximity
Authors: Ramos Viviane Kate Pereira , Landim Ossian Soares
Published: July 2023

This paper aims to analyze the issue of Distance Learning (EaD), through the perspective of two categories: distance and proximity. From such reflections, we intend to raise notes that make it possible to understand how the confrontation between face-to-face and non-face-to-face teaching (EaD) occurs, discussing to what extent this issue is an analytical contradiction. To this end, a literature review was carried out, dialoguing with the conception of the philosopher Martin Heidegger about proximity and distance, in order to problematize the debate beyond the question about metrage. About the distance education education, we highlight the contributions brought by Amaral Filho; in addition to dialoguing with authors such as Paulo Freire, based on the concepts of liberating education and pedagogy of autonomy; and the philosopher and sociologist Pierre Levy, through his important contributions to thinking about the science of information and communication in contemporary times. The initial reflections, brought in the present work, seek to contribute to broaden the discussions about face-to-face and distance learning in the contemporary context where education needs to (re)invent itself in a pandemic context.

Authors: Azevedo Nair Correia Salgado de , Vieira Julyara Grace , Oliveira Sabrina Maria de Souza
Published: July 2023

The general objective of this work was to understand how the work with playful cultures occurred in the context of literacy (1st year of elementary school) through remote teaching. As specific objectives, this study intended: a) To discuss the concept of playful cultures relating them to the processes of literacy and literacy; b) Understand the literacy process of the child in the 1st year of elementary school; c) Demonstrate the vision of teachers on the possibility of working with the playful in the context of literacy and their strategies through remote teaching. This research is characterized as qualitative, bibliographical, documentary and exploratory. Several techniques were used for data collection, such as research in publications of the Capes database, virtual libraries and websites of scientific journals between the years 2010 and 2021 on the subject; documentary analysis of the process of legalization and standardization of remote learning during the pandemic; the application of a questionnaire to generate data on teachers' views on playfulness and literacy during the Covid-19 pandemic. We conclude that the playful cultures were witnessed in this context through virtual games adapted from face-to-face to remote teaching. Despite the obstacles, we realized that the valorization or not of the playful cultures does not depend only on the teachers, but on other factors besides the planning, such as the lack of access that, in addition to compromising the interaction of the students, also affected the process of literacy and literacy.

Brazil is among the five largest milk producers in the world. In 2021 the national production was 35.3 billion liters of milk, of this total, 34% refers to milk produced in the Southeast region. Although the Southeast stands out in the national ranking by Regions, its average productivity is still considered low. The Temperature and Humidity Index (UTI) has been widely used in research involving the evaluation of thermal comfort conditions related to animal performance. This study aimed to analyze and make available monthly maps of UTI for the Southeast of Brazil. Air temperature and humidity data from INMET's automatic stations, from January 2007 to December 2021, were analyzed for consistency and possible failures of observational records were corrected. Subsequently, the UTI was estimated and geoprocessing techniques were applied to generate and make available the maps of monthly UTI averages for the Southeast of Brazil. According to the results presented in the maps, it is observed the predominance of the UTI class ≤ 70 between the months of May and September. In addition, it is noted that classes of high UTI values prevail in the months of December to March, indicating an environment condition not conducive to the thermal comfort of cattle.
The promotion of innovation and the management of knowledge within agro-industrial clusters. The case of Spanish clusters
Authors: Pimenta-Alonso Andrea Mara , Lucas Maria Raquel
Published: July 2023

In an economic approach, clusters are groups of vertically and horizontally linked and interrelated enterprises that can play a significant role in increasing their competitiveness through the adoption of innovative techniques and the exchange of knowledge. The cluster concept should be understood as a form of smart economy, supporting the participating enterprises in order to provide them with innovation, business strategies and technical support, thus increasing their competitiveness. However, there is little research that focuses on the performance of the agribusiness as such; most researchers have concentrated on understanding the role and benefits of clusters for the region as a whole. To fill this gap, this paper seeks to determine whether the fostering of innovation, competitive management and knowledge democratisation that should occur within a cluster has a direct economic effect on participating SMEs. To fill this gap, this paper seeks to determine whether the promotion of innovation, competitive management and democratisation of knowledge that should happen within a cluster has a direct economic effect on participating SMEs. The results obtained through the analysis of the evolution of variables such as financial profitability and the number of workers of the participating enterprises in two Spanish agro-industrial clusters in contrast with the enterprises in their region and the OECD as a whole, show that for the small and medium-sized enterprise segments, the innovation and information diffusion provided by the cluster affects them very positively by improving their performance, creating new jobs and bringing sustainable development to the sector, based on innovation and the training of the workforce.

Authors: Mansur Ana Mendonça , Moraes Jessica Bueno de
Published: July 2023

The offer of distance learning courses and blended learning has gained space in the academic scenario year after year. The method uses technology and the facilities provided by it become allies in the learning process. Factors such as time, place and age group are no longer an obstacle for those who want to improve the curriculum. In engineering courses, in particular, performance in common axis disciplines such as Calculus remains a major difficulty on the part of students. The study shows possible causes and association with students in both teaching modalities. It should be noted that the difficulty of entering a higher education institution, such as the entrance exam, becomes a water divider in terms of the educational basis obtained in secondary and elementary education.

This article focuses on the socioconstructivist educational approach that underlies the didactics of many teachers from the most diverse fields of knowledge. However, it will only be detailed here its implications with regard to literacy. The research that follows was based on a theoretical refinement in line with the neuroscientific perspective of how the human being learns to read and write. The result of the readings and inferences consists, widely and often, in the theories of Vygotsky and Piaget continue to be misinterpreted and transmuted to the scope of education, when they discuss precisely issues related to the biological and psychic development of the child, excluding propositions about the methodological natures of the process of reading and writing.

Published: July 2023

134Cs are produced directly as a fission product (low yield) and too obtained by neutron capture from 133Cs non-radioactive. The National Laboratory for Ionizing Radiation Metrology (LNMRI/IRD/CNEN) of Rio de Janeiro performed standardization of this radionuclide. A solution of 134Cs radionuclide was purchased from a commercial supplier for nuclear parameters determination such as activity and emission probabilities of some of its energies. 134Cs is a beta gamma emitter with 754 days of half-life. This radionuclide is used as a standard in environmental, water, and food control. It is also important to germanium detector calibration The gamma emission probabilities were determined mainly for some energies of the 134Cs by the efficiency curve method and the most uncertainties obtained were around 1.5 %.

Authors: Almeida Ana Luiza Normanha Ribeiro de , Simoni Lívia de
Published: July 2023

Introduction: Although CRC is the main malignant neoplasm of the gastrointestinal tract and the third most typical type of cancer in the world, little is discussed about its morbidity and mortality. Because the lack of visibility does not provide an adequate budget for preventive health policies, most diagnoses do not occur in the early stages of the disease, which not only makes it more expensive but also makes the therapeutic process difficult for the patient for the health team. To analyze the insufficient prevention of colorectal cancer. Objectives: to identify CRC mortality and relate it to the lack of prevention and information about the disease. Methodology: a literature review that will be carried out through already published material made at the University of Ribeirão Preto. It will be an observational study that will establish correlations between the social and scientific aspects of colorectal cancer.

This chapter has gathered scientific evidence on metoprolol as a pharmacological tool in various cardiovascular diseases. METHODOLOGY: This is a systematic review in which scientific articles published in Pubmed databases between 2021 and 2022 were selected. The following descriptors were used: metoprolol or pharmacokinetic, pharmacodynamics, efficacy, adverse effect, combined by means of the AND operator. A total of 46 articles were found, of which 17 met the selection criteria and, therefore, are included in this study. RESULTS: Regarding the clinical use of metoprolol, it was beneficial in the treatment of arrhythmias after resection of hepatocarcinoma, in cardiac improvement in patients with permanent pacemaker, in individuals with obstructive hypertrophic cardiomyopathy, and in addition to having been cited in the increase in survival in patients with type B aortic dissection. has been shown to be beneficial in both heart failure and carotid atherosclerosis, as well as hypothalamic obesity. With regard to adverse events, patients on metoprolol were more prone to nightmares than those exposed to another beta-adrenergic antagonist drug, such as carvedilol or labetalol. In addition, when compared with another drug, it did not have an advantage over esmolol for performing CT angiography and was less effective in antihypertensive therapy of men with erectile dysfunction. Finally, with regard to new methods of detection or therapeutic intervention of the use of metoprolol, one study was successful in discovering a new way to quantify metoprolol in rat plasma, while another recent study addressed relevant considerations in personalized therapy of the drug, based on the genetic polymorphism of CYP2D6. CONCLUSION: The present systematic review corroborates updates on the use of Metoprolol found in the current literature, contributing to the institution of personalized therapy for patients with cardiovascular disease.
Nodal flow and Situs inversus: A literature review
Authors: Garcia Angela Chaves de Oliveira , Caputo Lucélia Rita Gaudino , Andrade Wellington Venâncio de , Latorraca Elder Francisco
Published: July 2023

Variations of situs solitus totalis, the normal organ disposition pattern, involve dextrocardia, situs inversus, situs inversus totalis and situs ambiguous. These laterality defects have been documented for more than 400 years, and a connection to ciliary abnormalities has been elucidated by observing cilia from the primitive node, which can promote “nodal flow”, possibly necessary for the development of left-right asymmetry. The aim of this work was to perform a literature review, showing variations in the usual anatomy and the connection between nodal flow and normal asymmetric pattern. A narrative review was carried out with articles from the MEDLINE/PubMed, SciELO and LILACS databases and with books relevant to the theme. The initial embryonic development comprises the formation of the organizing structure, a primitive node, and its cilia are responsible for the nodal flow, determinant in many vertebrates in the breaking of the embryonic bilateral symmetry. The formation of asymmetry is associated with morphogenic gradients to the left of the node, the model of two cilia and the mechanism of nodal vesicular plots, until it results in organogenesis. Ciliary abnormalities configure clinical manifestations in disorders such as Primary Ciliary Dyskinesia and Kartagener syndrome. The nodal flow, in fact, is important in normal anatomical standardization, and the cilia are necessary for the configuration of situs solitus totalis.

In Brazil, more and more, adolescents are affected by STIs. Therefore, the objective of this research is to present the prevalence and evolution of cases of sexually transmitted infections in adolescents in Brazil. This is an observational epidemiological study with a quantitative approach and descriptive analysis on data related to the prevalence of STI in adolescents aged 10 to 19 years between 2010 and 2021 in Brazil. Data were extracted from DATASUS electronic databases. In this period, there were 86,601 cases of syphilis, mainly between 15 and 19 years old, with a higher prevalence in incomplete high school and brown race, and 56.17% were female, with the most affected region being the southeast (50.53%). Regarding hepatitis B, there was a prevalence in females with 56.17%, with the most affected region in the north with 39.58%, especially between 15 and 19 years with 92.17%, and higher prevalence in incomplete high school (19.53%) and in the race ver parda (51.26%). There were 10,129 cases of AIDS, mainly in the age group of 15 to 19 years with 89.81% and in the brown race with 31.53%, 59.98% were male, with the most affected region being the southeast with 36.2%, among them 25.52% with incomplete elementary education. The study concluded that measures are needed that tend to decrease the prevalence of STIs in adolescents in Brazil. Therefore, it is important to carry out campaigns, especially in schools, in order to spread this information to reach our target audience, which are adolescents from 10 to 19 years old.

Introduction: Anterior Cruciate Ligament (ACL) injuries are common among athletes participating in high-demand sports. The ACL is an essential ligament in the knee that provides stability against unwanted movements. The incidence of ACL injuries in the United States is significant, becoming a concern for athletes and sports medicine professionals. This text provides an overview of ACL injuries, including their anatomy, function, risk factors, prevention strategies, and effective rehabilitation techniques. ACL rupture can impact athletic performance and require extensive rehabilitation. Methodology: A literature review was conducted from 2010 to 2022 using the databases PubMed, Scielo, and Medline to provide an updated overview of the relationship between Anterior Cruciate Ligament (ACL) injuries and athletes. Twenty-six articles addressing the clinical, anatomical, pathological, and treatment aspects of ACL injuries in athletes were selected. These articles were published in English, Spanish, or Portuguese. The methodological quality of the articles was evaluated, and the data were qualitatively analyzed, grouping the results by similarity. The data synthesis was presented descriptively, highlighting key information about the clinical, anatomical, pathological, and treatment aspects of ACL injuries in athletes. Discussion: This work discusses risk factors, prevention, rehabilitation, surgical treatment, psychological impact, long-term consequences, recent research, and specific considerations for female athletes related to Anterior Cruciate Ligament (ACL) injuries. Risk factors for ACL injuries include increased general joint laxity, increased anterior-posterior knee joint laxity, female sex, previous ACL reconstruction, and familial predisposition to ACL injury. The incidence of ACL injuries varies among different sports and sexes. Injury rates are higher in sports such as soccer, basketball, and baseball/softball. Injury prevention strategies are also discussed. Conclusion: Anterior Cruciate Ligament (ACL) injuries are a significant concern for athletes and sports medicine professionals. A comprehensive approach involving prevention, rehabilitation, and safe return to sport is necessary to reduce the risk of ACL injuries in athletes and prevent long-term consequences. Adequate training techniques, injury prevention programs, and effective rehabilitation approaches play a crucial role in minimizing the risk of ACL injuries in athletes. Additionally, physiotherapists play a vital role in the prevention and rehabilitation of these injuries, and it is essential for them to stay updated with the latest research to provide the most effective care to affected athletes.
Additional effects of transcutaneous electrical nerve stimulation associated with vertebral joint mobilization on musculoskeletal variables of individuals with low back pain

Published: July 2023

Low back pain (LBP) is a musculoskeletal complaint that can be defined as pain or discomfort referred to the lower part of the spine, between the last thoracic vertebra and the first sacral vertebra, above the upper gluteal line, and which may or may not radiate to the lower limbs. Highly prevalent, it affects about 84% of the adult population at some point in life, being classified as acute when it lasts up to 6 weeks, subacute when from 6 to 12 weeks and chronic if for more than 12 weeks 2. LBP is a public health problem, as it is related to functional disability, decreased quality of life, social and economic losses, both indirect, as it leads to absenteeism, withdrawal from work activities and/or disability retirement, and direct, due to public health costs with medical care and procedures related to LBP and its biopsychosocial consequences 3,4. The etiology of low back pain is complex and multifactorial, and can be specific when due to a known pathology or factor, and nonspecific when the causes are inevitable 5. However, they are often associated with an imbalance between the effort required to perform the activities and the insufficient capacity of the musculoskeletal system to do so 6, as well as other agents of mechanical origin, such as disc, joint, muscle, ligament and nerve alterations.

Este artigo representa um estudo profundo e minucioso sobre a complexa interação entre a tuberculose (TB) e a insuficiência renal crônica (IRC), duas condições médicas graves que têm implicações significativas quando coexistem em pacientes hospitalizados em unidades de terapia intensiva (UTIs). Mediante uma extensa revisão de literatura, é explorada a intricada relação entre TB e IRC, lançando luz sobre os processos patofisiológicos subjacentes, as implicações clínicas e as interações medicamentosas que surgem quando essas condições coexistem. Este artigo também examina os desafios que essas comorbidades apresentam para os profissionais de saúde na UTI - desde o diagnóstico até o tratamento, passando pela prevenção e controle de infecções. Além disso, são discutidas estratégias potenciais para aprimorar o cuidado ao paciente, focando em abordagens multidisciplinares e o desenvolvimento de diretrizes clínicas especializadas. O impacto dessa comorbidade na qualidade de vida dos pacientes é analisado, levando em conta não apenas a morbidade e mortalidade, mas também a duração da hospitalização, as dificuldades psicossociais e o prognóstico a longo prazo.

Dentre os medicamentos mais prescritos no mundo, temos os Inibidores de Bombas de Prótons (IBPs), utilizados para tratamento de doenças pépticas. Estudos recentes têm associado o uso de IBPs à demência. Baseado nisso, a presente revisão sistemática selecionou artigos científicos publicados no corrente ano, na base de dados Pubmed, com os descritores: “proton pump inhibitors” e “dementia” combinados por meio do operador booleano AND. Os estudos encontrados mostram divergências na comunidade científica sobre o declínio cognitivo estar associado ao uso prolongado de IBP. Autores encontraram maior risco de demências associado ao uso de IBPs, sugerindo possível efeito cumulativo. A interação com a via colinérgica parece ser relevante. Os resultados encontrados contribuem para um alerta sobre o uso indiscriminado dessa classe terapêutica, além da necessidade da instituição de terapêutica personalizada ao paciente portador de demência.

Published: July 2023

Este artigo apresenta uma melhoria no processo de soldagem linear de uma indústria de implementos agrícolas. Em busca de maior competitividade, foi estudado um projeto em que aumentasse a capacidade interna de produção a fim de se obter uma redução de tempo no processo de soldagem em um lead-time pré-definido visando aumentar a produtividade de implementos agrícolas fabricados, sem aquisição de novas máquinas, reaproveitando os recursos disponíveis. O implemento agrícola, foco da pesquisa, constitui-se de partes e conjuntos com longas extensões de solda linear onde se é exigido um alto rendimento no processo. Para executar uma soldagem linear de baixo grau de automatização, são necessários controle direcional de velocidade de deslocamento e parâmetros de soldagem. A viabilização desta melhoria foi consolidada com a adaptação de uma máquina pantográfica de oxicorte fora de uso. Como o pantógrafo oxicorte é munido destes requisitos, adaptou-se uma tocha de solda, do processo MIG/MAG, onde se encontrava o maçarico de corte, sendo desenvolvido um dispositivo para apoio e travamento das peças. Com isto foi possível aumentar o lote econômico de produtos no lead-time determinado. A capacidade de soldagem disponível aumentou o rendimento e a eficiência, sem aumentar o quadro de trabalhadores ou turnos de trabalho. Além da redução de custo, testes de resistência mecânica foram realizados com o objetivo de constatar uma garantia do processo.

The role of microbial diversity in microbial electrosynthesis

Bacteria are often painted as the enemy of humanity. Before the discovery of antibiotics, a wound getting infected was frequently a death sentence. Even with modern medicine, infections such as C. difficile and infectious diseases such as tuberculosis continue to kill many people globally. Crop blights and diseases among livestock cause extensive monetary losses and threaten food security in affected areas. With all of these reasons to distrust bacteria, it may come as a surprise that certain microbes are immensely beneficial to humanity. Unfortunately, they rarely get to enjoy the limelight. Our gut microbiomes help us digest complex molecules in our food, and many of the antibiotics we discovered were invented by microbes facing competition from their neighbors. We have leveraged microbes to process sewage and waste for centuries and to ferment food for millennia.

Objective: Cryptorchidism is one of the main causes of infertility and can result in testicular cancer. This study aimed to present quantitative data on the damage caused by cryptorchidism using stereological analysis. Methods: Thirty newborn rats were randomly divided into control and experimental groups. The experimental group underwent surgery to induce unilateral cryptorchidism in the left testis, whereas the control group underwent a sham surgical procedure 18 days after birth. The testes were removed at designated time points (40, 63, and 90 days after birth) for stereological evaluation and sperm analysis. Total testicular volume, interstitial tissue volume, seminiferous tubule volume and length, and seminiferous epithelium volume and surface area were measured. Other parameters, such as sperm count, sperm morphology, and sperm tail length, were also examined. Results: Statistically significant differences (p<0.05) were observed between the experimental and the control groups at different ages regarding the volumes of various parameters, including the surface area of the germinal layer, the length of the seminiferous tubules, sperm count, and sperm morphology. However, no significant differences were observed in the epithelial volume and the sperm tail length of the groups. Conclusion: Given the substantial effect of cryptorchidism on different testicular parameters, as well as the irreversible damage it causes in the testes, it is important to take this abnormality seriously to prevent these consequences.

A Zsolcai-halmokon előforduló löszgyepeket, a halmok talajtani adottságait, növényzetét és állatvilágát vizsgáltuk. A florisztikai szempontból jól feltárt halmokról viszonylag kevés ismerettel rendelkezünk az ökológiai szempontból izolált, reliktum előfordulásoknak tekinthető löszgyep foltok aktuális dinamikájáról: az izolált előfordulás, a csekély kiterjedés, a rendszeres tüzek, emlősjáratok általi talajfelszín-bolygatások fajösszetételre, állományszerkezetre gyakorolt hatásai kevésbé feltártak. A tanulmányban a növényzetet érintő szegélyhatásra vonatkozó megállapításokat ismertetjük, amely a gyep szegélyében, mintegy 3 méteres szélességben okoz szignifikáns különbségeket a növényzet fajösszetétele, a természetességi értékszámok átlaga és a fajszám tekintetében. A szántóföldi és ruderális gyomfajok felszaporodása eddig a szélességig a legerőteljesebb. A gyep központi részében előforduló pedoturbációk, rendszertelen tűzesetek mintázat- és szerkezetalakító szerepe egyelőre nem kellően tisztázott. A Zsolcai-halmok az állatvilág szempontjából igen kicsi kiterjedésűek (0,8 ha), de az eddigi vizsgálataink alapján számos védett faj található rajtuk. Az antropogén halmok az állatvilág számára részben igen száraz, napfényes, meleg élőhelyet alakítanak ki (déli oldal), míg a halmok északi oldala sűrű növényzetű, kiegyenlítettebb vízháztartása révén magasabb diverzitású.

Eurázsia sztyeppéinek emberalkotta formakincsei a kunhalmok. Az utóbbi századokban elsősorban a régészet tudománya vizsgálta ezeket a formációkat, ma azonban tudjuk, hogy természet- és környezettudományi szempontból a határ- és őrhalmok, a lakó-, valamint sírdombok egyaránt kiemelkedően fontos értékek képviselői. A halmok építésével egyidős ősi környezet rekonstrukciója az eltemetett egykori talajszintek és a halom kultúrrétegeinek vizsgálatával valósítható meg. Ezekkel az elemzésekkel hozzájárulhatunk az Alföld holocénkori környezeti képének pontosításához és jelenkori tájhasználati kérdések tisztázásához éppúgy, ahogy okszerűvé, megalapozottabbá tehetjük és kiterjeszthetjük egyes területek természetvédelmi kezeléseit is. Amellett, hogy a kurgánok jelentős növény-, állat-, talaj- és felszínalaktani értékek hordozói, az alföldi táj védelemre és megismerésre érdemes, meghatározó tájesztétikai és kultúrtörténeti elemei is egyben. Jelen munkában a Szolnok-Túri-síkon elhelyezkedő Bán-halmot és annak közvetlen környezetét, valamint kultúr- és természeti történetét elemezzük a botanika, talajtan, paleotalajtan és a geomorfológia eszközeivel. A jelenkori vegetáció feltérképezése, aspektusok dinamikája és a halom átfogó állapotfelmérése jó alapot szolgáltat a védelem, és egy esetleges rehabilitáció megvalósításához. Az eltemetett, paleotalaj vizsgálati eredménye réti jellegű talajképződést mutatott, míg a recens, a halom palástján kialakult fiatalabb talajképződmény a csernozjom jelleget valószínűsíti. A halom sztratigráfiai elemzése, illetve az egyes talajparaméterek – kiemelten az összes foszfor – ingadozása a halom komplex történeti ökológiai fejlődésére, illetve időben többszöri birtokba vételre utal.
Requirements for the management of protected areas according to the UNESCO World Heritage Convention and IUCN categories

Methodological and standardized management requirements for protected areas have become a central issue in nature conservation over the last years. The article takes a closer look on the current international standards laid out by the World Heritage Convention for natural sites and by IUCN for protected areas. Both actors play a central role in the way we approach and deal with protected areas globally. Both are influenced by local developments, local management cultures and still have to have a global approach. The goal is to examine how the World Heritage community has tackled these problems and in which form it is today adapting to current developments. The first part lays out the management principles for the UNESCO Natural World Heritage properties according to the overarching goal of protecting the Outstanding Universal Value (OUV) of a site. Part two summarises the management principles of protected nature reserves following the IUCN categories. Their aim is to protect (and conserve) nature with its ecosystems, species, biodiversity etc. The conclusion reflects on management of protected nature sites in general and how the two above examined concepts interrelate.
Az éghajlatváltozás, hatásai és az intézkedések az IPCC negyedik értékelő jelentése tükrében
Authors: Nováky Béla
Published: July 2023

Az Éghajlat-változási Kormányközi Testület (IPCC) 2007-ben közreadott Negyedik Értékelő Jelentése megállapította, hogy a Föld éghajlata az ipari forradalom óta eltelt időben melegedett. A melegedés nagyon valószínű oka, hogy a különféle emberi tevékenységek során a növekszik a légkörbe jutó, a természetes üvegházhatást fokozó üvegházgázok, mindenekelőtt a szén-dioxid mennyisége. Amennyiben a kibocsátás a jelenlegi vagy azt meghaladó ütemben folytatódik, a globális melegedés mértéke a 21. század végére elérheti a 2,5–5,5 °C-ot. A globális melegedés hatással lesz a regionális éghajlatra, a természetes fizikai és biológiai rendszerekre, a humán rendszerekre. Számos jelzés van arról, hogy a változások máris elkezdődtek. A melegedés következtében olvad a sarkkörüli tengerjég, csökken a gleccserek és a permafroszt kiterjedése, emelkedik a tengerek vízszintje, a száraz éghajlatú térségekben csökken a hasznosítható vízkészlet, gyakoribbá válnak a szélsőséges időjárási jelenségek (aszály, árvizek). Az éghajlatváltozás a nem éghajlati hatásokkal (földhasználati változások, szennyezés, a természeti erőforrások túlzott igénybevétele) együtt veszélyezteti számos ökoszisztéma fennmaradását, különösen a 2–3 °C-ot meghaladó globális melegedésnél. Folytatódik a biogeográfia övezetek eltolódása, pl. erdők északi terjeszkedése a tundra rovására, a szubtrópusi területek bővülése a trópusok rovására. Az éghajlatváltozás veszélyezteti a biodiverzitást, az eddig ismert fajok 20–30%-a kipusztulhat. A tengerek melegedése miatt eltűnhet a koralltelepek jó része, a sarki jég olvadása miatt szűkülhet egyes fajok élettere, a tengervízszint emelkedése miatt veszélybe kerülnek a parti mangrove-erdők. A humán szférában nő a vízhiányos területeken élők száma, hosszabb távon romlik az élelmiszer-ellátás biztonsága, nő a fertőzéses betegedések kockázata. A tengerszint emelkedése több millió parti lakos biztonságát veszélyezteti. Az éghajlatváltozás kedvezőtlen hatásainak kivédésére vagy csökkentésére két út kínálkozik: az egyik az éghajlatváltozás mérséklése, a másik az új éghajlati viszonyokhoz való alkalmazkodás.
A Koppánymonostori-sziget kialakulása és tájtörténete

A dunai szigetek mai képének kialakulásában nagy szerepet játszottak a 19. század végén lezajlott folyószabályozási munkálatok, mellékág-lezárások, ármentesítések, amelyeknek következtében a mellékágakban a víz folyása lelassult, a szállított hordalék folyamatosan lerakódott, s így megkezdődött egy dinamikus feltöltődési folyamat, amely a mellékágak folyamatos feliszapolódását eredményezte. Ennek követ- keztében, a nyári hónapokban a főmedertől leválasztott mellékágak néhol teljesen kiszáradnak, felgyorsítva ezzel a szukcessziós változásokat, utat engedve az inváziós fajok terjedésének.Így történt ez a Komárom város nyugati partjánál elhelyezkedő Koppánymonostori-sziget esetében is. A régi katonai térképek az 1780-as években egy nagyobb és három kisebb szigetet ábrázolnak, egységesen erdőborítással, később két szigeten az erdőt letermelték, s helyén mocsaras foltokkal tarkított rét jött létre. A sziget életében bekövetkezett legnagyobb változások a 1800-as évek második felére tehetők, amikor partját sok helyen kőszórásokkal szegélyezték, a kisebb szigeteket a nagyhoz csatolták, s a mellékágat kőgáttal leválasztották a főmedertől. Ekkortájt a kis szigetek felszínborítása a szukcesszió előrehaladtával főként erdő volt, egyedül a nagy sziget keleti és középső részein figyelhető meg kaszálórét, s két foltban ártéri gyümölcsös.Összességében a koppánymonostori szakaszon a Duna régebben még önmaga alakította dinamikusan saját medrét, s egy kisebb meanderkanyarulat után, a helyi lassabb folyás eredményeképpen rakta le a sziget alapjait, amely a 19. századi folyószabályozásokig folyamatosan változott. Azóta a hajózás érdekében a partokat mesterséges kőszórásokkal szegélyezték, egyes átalakulási, feltöltődési folyamatok, így a szukcessziós változások is felgyorsultak. A szabályozási munkálatok, kőszórások, gátak miatt ezen a Duna szakaszon újabb szigetek születése lehetetlenné vált, így a mára oly ritkaságnak számító ártéri élőhelyek megőrzése kiemelt természetvédelmi feladat.
