Optimizing the carbonic anhydrase temperature response and stomatal conductance of carbonyl sulfide leaf uptake in the Simple Biosphere model (SiB4)
Authors: Cho Ara , Kooijmans Linda M. J. , Kohonen Kukka-Maaria , Wehr Richard , Krol Maarten C.
Published: July 2023

Abstract. Carbonyl sulfide (COS) is a useful tracer to estimate
gross primary production (GPP) because it shares part of the uptake pathway
with CO2. COS is taken up in plants through hydrolysis, catalyzed by
the enzyme carbonic anhydrase (CA), but is not released. The Simple
Biosphere model version 4 (SiB4) simulates COS leaf uptake using a
conductance approach. SiB4 applies the temperature response of the RuBisCo
enzyme (used for photosynthesis) to simulate the COS leaf uptake, but the CA enzyme might respond differently to temperature. We introduce a new
temperature response function for CA in SiB4, based on enzyme kinetics with
an optimum temperature. Moreover, we determine Ball–Woodrow–Berry (BWB)
model parameters for stomatal conductance (gs) using observation-based estimates of COS flux, GPP, and gs along with meteorological measurements in an evergreen needleleaf forest (ENF) and deciduous broadleaf forest (DBF). We find that CA has optimum temperatures of 20 ∘C (ENF) and 36 ∘C (DBF), which is lower than that of RuBisCo (45 ∘C), suggesting that canopy temperature changes can critically affect CA's catalyzation activity. Optimized values for the BWB offset parameter are similar to the original value (0.010 ± 0.003 mol m−2 s−1), and optimized values for the BWB slope parameter (ENF: 16.4, DBF: 11.4) are higher than the original value (9.0) at both sites. The optimization reduces prior errors on all parameters by more than 50 % at both stations. We apply the optimized gi and gs parameters in
SiB4 site simulations, thereby improving the timing and peak of COS
assimilation. In addition, we show that SiB4 underestimates the leaf
humidity stress under conditions where high vapor pressure deficit (VPD) should limit gs in the afternoon, thereby overestimating gs. Furthermore, global COS biosphere sinks with optimized parameters show smaller COS uptake in regions where the air temperature is over 25 ∘C, mostly in the tropics, and larger uptake in regions where the temperature is below 25 ∘C. This change
corresponds with reported deficiencies in the global COS fluxes, such as
missing sinks at high latitudes and required sources in the tropics. Using
our optimization and additional observations of COS uptake over various
climate and plant types, we expect further improvements in global COS
biosphere flux estimates.

Published: July 2023

Abstract. As one of Earth's most productive marine ecosystems, the
Peruvian upwelling system transports large amounts of biogenic matter from
the surface to the deep ocean. Whilst particle sinking velocity is a key
factor controlling the biological pump, thereby affecting carbon
sequestration and O2-depletion, it has not yet been measured in this
system. During a 50 d mesocosm experiment in the surface waters off the
coast of Peru, we assessed particle sinking velocities and their
biogeochemical and physical drivers. We further characterized the general
properties of exported particles under different phytoplankton communities
and nutritional states. Average sinking velocities varied between size
classes and ranged from 12.8 ± 0.7 m d−1 (particles 40–100 µm) to 19.4 ± 0.7 m d−1 (particles 100–250 µm)
and 34.2 ± 1.5 m d−1 (particles 250–1000 µm) (± 95 % CI). Despite a distinct plankton succession from diatoms to
dinoflagellates with concomitant 5-fold drop in opal ballasting, substantial
changes in sinking velocity were not observed. This illustrates the
complexity of counteracting factors driving the settling behaviour of marine
particles. In contrast, we found higher sinking velocities with increasing
particle size and roundness and decreasing porosity. Size had by far the
strongest influence among these physical particle properties, despite a high
amount of unexplained variability. Our study provides a detailed analysis of
the drivers of particle sinking velocity in the Peruvian upwelling system,
which allows modellers to optimize local particle flux parameterization. This
will help to better project oxygen concentrations and carbon sequestration
in a region that is subject to substantial climate-driven changes.
Paul J. Crutzen – a pioneer in Earth system science and a founding member of the journal “Atmospheric Chemistry and Physics”
Authors: Müller Rolf , Pöschl Uli , Koop Thomas , Peter Thomas , Carslaw Ken
Published: July 2023

Abstract. Paul J. Crutzen was a pioneer in atmospheric sciences. At the same time, he was a kind-hearted, humorous person with empathy for the private lives of his colleagues and students, but also with the highest scientific standards for himself and for others. He made fundamental scientific contributions to a wide range of scientific topics in all parts of the atmosphere, from the mesosphere to the stratosphere and to the troposphere near the ground. In particular, he was the first to describe the NOx -driven ozone depletion cycle in the stratosphere, he developed the first mechanisms for the chemical formation of ozone in the troposphere, he provided key ideas to explain the “ozone hole”, and he made fundamental discoveries about the effects of biomass burning on the troposphere. Understanding and addressing the causes of man-made air pollution and climate change was the driving motivation for his scientific work. In his work he did not shy away from challenge and provocation. He pioneered the concept now known as “nuclear winter” and initiated the reopening of the debate on geoengineering. He also brought the term “Anthropocene” to the popular debate. In 2000, Paul was among the founders of the journal “Atmospheric Chemistry and Physics”, which was unique at the time in providing public discussion of published preprints, and also what we now call “open access” to published articles. Paul’s work on human impacts on atmosphere and climate has had a profound impact on the environmental policies of many countries for decades. In the future, his work will continue to be a guide for generations of scientists and environmental policy makers to come.
Bayesian hierarchical modelling of sea-level extremes in the Finnish coastal region
Authors: Räty Olle , Laine Marko , Leijala Ulpu , Särkkä Jani , Johansson Milla M.
Published: July 2023

Abstract. Occurrence probabilities of extreme sea levels required in coastal planning, e.g. for calculating design floods, have been traditionally estimated individually at each tide-gauge location. However, these estimates include uncertainties, as sea-level observations typically have only a small number of extreme cases such as annual maxima. Moreover, exact information on sea-level extremes between the tide-gauge locations and incorporation of dependencies between the adjacent stations is often lacking in the analysis. In this study, we use Bayesian hierarchical modelling to estimate return levels of annual maxima of short-term sea-level variations related to storm surges in the Finnish coastal region. We use the generalised extreme value (GEV) distribution as the basis and compare three hierarchical model structures of different complexity against tide-gauge-specific fits. The hierarchical model structures allow us to share information on annual maximum sea levels between the neighbouring stations and also provide a natural way to estimate uncertainties in the theoretical estimates. The results show that compared to the tide-gauge-specific fits, the hierarchical models, which pool information across the tide gauges, provide narrower uncertainty ranges for both the posterior parameter estimates and the corresponding return levels in most locations. The estimated shape parameter of the GEV model is systematically negative for the hierarchical models, which indicates a Weibull type of behaviour for the extremes along the Finnish coast. The negative shape parameter also allows us to calculate the theoretical upper limit for the annual maximum sea levels on the Finnish coast. Depending on the tide gauge and hierarchical model considered, the median value of the theoretical upper limit was 47–73 cm higher than the highest observed sea level.

Authors: MOHAFA Lereko , GEORGE Mosotho J.
Published: July 2023

The unique nature of online teaching and learning has its own affordances and challenges. The purpose of this study was to assess science pre-service teachers’ perceptions about efficiency of online teaching and learning in science after experiencing it first-hand during the hard lockdowns due to Covid-19 pandemic. Mixed methods approach, with closed and open-ended questionnaires, was adopted to establish: What perceptions the pre-service teachers have about online teaching and learning in respect of effective teaching and effective assessment? What correlations can be drawn from pre-service science teachers experience of online teaching and learning with their perceptions? And to what extent this mode of teaching prepared these pre-service teachers to use it in their teaching practice? Descriptive statistics and content analysis of data revealed that participants rated online teaching and learning low and had a challenging experience in terms of collaboration, access to material and making meanings out of some science concepts. Participants reported low confidence relating to perceived ease of use and perceived usefulness of online teaching and learning. The study concludes that the harsh experiences were the main contributing factors to the observed perceptions of participants as neither the lecturers nor these student-teachers were prepared for this mode of teaching and learning. Therefore, this study recommends that support mechanisms for students should be made available for online teaching and learning even under emergency situations. Pre-service teachers should also be given a chance to experience online teaching and learning under normal circumstances if they are to incorporate it in their teaching.

El aprendizaje automático en la educación superior como herramienta para optimizar los índices de deserción y detectar los factores que la ocasionan
Authors: Ruiz Martínez William
Published: July 2023

La deserción escolar se ha convertido en una de las grandes preocupaciones de las instituciones de educación superior ya que de la permanencia de sus estudiantes depende en cierto grado su propia sustentabilidad económica. Para nadie es un secreto que la actual situación económica del país, y otros factores como la reticencia de los estudiantes a cursar programas educativos extensos, cada vez llaman menos la atención de los estudiantes. Atenuantes como el difícil y exigente panorama laboral y los elevados costos de matrículas de ciertas instituciones educativas contribuyen a desincentivar el ya minado y reducido mercado estudiantil. Es por ello que las universidades deben reinventarse y plantear nuevas alternativas y métodos de educación donde la realidad laboral coincida y sea congruente con los conocimientos impartidos en las aulas de clase. Para poder estar seguro de cuáles son las causas de la deserción escolar no basta con presumir, sino que se deben comprobar los verdaderos factores de la deserción.. Consecuentemente el objetivo del presente artículo es presentar una revisión de diferentes estudios relacionados con la deserción escolar en ámbitos de educación superior y establecer cómo se puede predecir dicha deserción basándose en la aplicación de diferentes modelos y algoritmos de aprendizaje.
Control microbiológico en la preparación de ensaladas de vegetales frescos a través de aderezos
Authors: Ortiz Tobar Diana Paola
Published: July 2023

Las ensaladas son una parte esencial de la alimentación y la calidad microbiológica es fundamental al momento de consumir alimentos. Las enfermedades transmitidas por alimentos (eta) son provocadas por microorganismos como Salmonella, Escherichia Coli, mesófilos, coliformes totales y coliformes fecales. La presente investigación se basa en la presencia de microorganismos patógenos en ensaladas con y sin aderezos de cuatro puestos de venta ambulante de la ciudad de San Juan de Pasto. El estudio es cuantitativo y descriptivo. Para ello, se realizan pruebas de análisis microbiológico en el laboratorio de la Universidad Mariana. Los resultados indican que las muestras de ensaladas de vegetales frescos sin aderezo tienen una alta contaminación de coliformes totales, mesófilos y Staphylococcus, superior a 300 unidades formadoras de colonias (ufc). Por otro lado, el aderezo añadido a las muestras tuvo un efecto positivo eliminando de forma total a los coliformes fecales y disminuyendo parcialmente el número de ufc de los demás microorganismos, pero no totalmente por lo que no pudo lograr la cantidad mínima para consumo humano. Se concluye que los vegetales que se utilizan en ensaladas frescas pueden contener microorganismos a la hora de ser consumidos, si no se aplican buenas condiciones sanitarias, y que la adición del aderezo tiene un efecto positivo sobre la actividad microbiana en las ensaladas, pues ayuda a controlar ciertos microorganismos como los coliformes fecales.

Análise do componente arbustivo-arbóreo regenerante em área de mata ciliar degradada no Cariri Paraibano.
Authors:   , Sabrina Ovídeo de Araújo Jéssica
Published: July 2023

A Caatinga é o terceiro Bioma mais degradado do Brasil. Nessa região a disponibilidade hídrica faz com que as matas ciliares sejam os ambientes mais afetados com a retirada da vegetação para realização de atividades agrícolas. A regeneração natural consiste na interação de processos naturais que resultam na recuperação do ecossistema florestal e seu estudo permite efetuar projeções sobre o desenvolvimento futuro da floresta. Portanto, objetivou-se com este trabalho avaliar o banco de jovens regenerantes em um ecossistema ribeirinho degradado no município de Livramento, semiárido paraibano. A pesquisa de campo foi executada em uma área no município de Livramento/PB, situado na Microrregião do Cariri Ocidental. As atividades foram apoiadas em excursões exploratórias realizadas inicialmente em vários pontos do município, além da análise de cartas e mapas da vegetação. O monitoramento do componente arbustivo-arbóreo regenerante foi realizado mensalmente no período de julho a novembro/2018. O banco de indivíduos jovens foi analisado mediante a implantação de 50 parcelas de 1 X 1 m. Todos os indivíduos jovens lenhosos presentes nestas parcelas, com altura < 1,00 m e DNS < 3 cm, foram etiquetados, numerados e identificados pelo nome científico, medindo-se os valores de altura total com uma régua graduada e para diâmetro utilizou-se um paquímetro digital. Na análise estrutural da vegetação utilizaram-se os seguintes parâmetros: frequência, densidade e classes de altura e diâmetro da regeneração natural. No conjunto das 50 parcelas amostradas no riacho Verde foram registrados e identificados no inventário 19 indivíduos, distribuídos em três famílias, seis espécies, seis gêneros e uma indeterminada. O componente predominante foi o arbóreo. As famílias com maior número de espécies foram Euphorbiaceae com três, seguida por Fabaceae com duas. Das 50 parcelas amostradas, a espécie que obteve a maior frequência foi a Mimosa tenuiflora (Willd.) Poir. (11 parcelas). Relacionado às classes de altura e diâmetro observou-se uma maior distribuição de indivíduos nas classes de menor valor. Para a altura, mais de 40% dos indivíduos se concentraram na menor classe de 0,01 a 0,25 m e o diâmetro seguiu o mesmo padrão, com o maior número de indivíduos na primeira classe (1,01 a 3,00 cm), chegando o percentual acima 45% do total de indivíduos registrados. Observou-se que na parcela 42 ocorreu o maior número de indivíduos (cinco), as parcelas 21, 43 e 45 (três cada), sendo o menor número (um) na parcela 49 e nas demais não houve indivíduos. De modo geral, a área em estudo apresentou uma composição florística com um número reduzido de espécies, quando comparada com outros ecossistemas ribeirinhos, o que demonstra o elevado grau de antropização da área, que acentua cada vez mais o nível de degradação. Portanto, as informações geradas no trabalho se definem como importantes contribuições para as estratégias de restauração de ambientes degradados.
Caracterização funcional e estrutural comparativa in silico de uma proteína PR-5 do tipo taumatina de Poncirus trifoliata.
Authors:   , Alexandre de Abreu Rayane
Published: July 2023

A busca por novos antifúngicos tem direcionado esforços para proteínas da imunidade inata de plantas, conhecidas como proteínas relacionadas à patogênese, particularmente da família PR-5. Indicar novos genes que codificam proteínas antifúngicas, dentre milhares de sequências gênicas disponíveis em bancos de dados, é uma especialidade da bioinformática de grande interesse na era pós-genômica, que requer conhecimentos sobre funções e estrutura de proteínas. Neste contexto, este trabalho descreve a caracterização funcional e estrutural comparativa in silico de uma proteína PR-5 do tipo taumatina de Poncirus trifoliata, denominada PtTLP, por uma estratégia que envolveu técnicas de modelagem e docking molecular. A estrutura proposta para a PtTLP apresentou um modelo estável e representativo, dentro dos padrões avaliados, o que pode ser considerado uma representação muito próxima da estrutura real da proteína. A sua estrutura obtida por modelagem comparativa evidenciou características típicas de proteínas TLPs, incluindo a existência de três domínios, oito pontes de sulfeto e uma fenda interdomínios carregada eletronegativamente, denominada sítio ativo da proteína. O modelo construído foi depositado na base de dados PMDB, disponível online. PtTLP interagiu com as moléculas de 1,3-β-glucana, 1,4 -β-glucana, 1,6 -β-glucana, N-acetilglucosamina, 1,3-β-D-glucose e 1,4-β-D-glucose, com interações comprovadas por energias negativas, pela orientação das estruturas na região que comporta o sítio ativo da proteína, ao contrário da interação com a molécula de quitina, que apresentou energia de ligação positiva e ancorou fora do sítio ativo da proteína. Estes dados dão evidências para possíveis atividades de β-glucanase e de ligação a monômeros de carboidratos solúveis para PtTLP e abrem um leque de questões a serem investigadas acerca desta proteína. Estas atividades precisam ser experimentalmente comprovadas, visto que esta proteína é forte candidata, como antifúngico e antioomiceto, para aplicações biotecnológicas na agricultura, na indústria farmacêutica e alimentícia.

The problem in this study was that there were some students who had not been able to understand the questions properly because of their limited Arabic vocabulary, so they could not answer questions in Arabic correctly and correctly. Meanwhile, teachers do not fully understand the characteristics of students' intelligence, so that students who should receive special attention and guidance in mastering Arabic vocabulary receive less attention. This study aims to determine the relationship between Linguistic Intelligence and Arabic Vocabulary Mastery in Grade VII MTs Al Amar Legok Tangerang. The research method used in the preparation of this thesis is a correlation method with the type of field research (field research). The population in this study amounted to 134 students. In this study, researchers used samples taken from the population, namely 60 respondents consisting of 14 students in class VII-1, 15 students in class VII-2, 16 students in class VII-3, and 15 students in class VII-4. to obtain data the researcher used an instrument in the form of a questionnaire statement on variable X (Linguistic Intelligence) and an instrument in the form of a test for variable Y (Arabic Vocabulary Mastery). Researchers carried out the correlation coefficient technique and the significance of the correlation coefficient on both variables. The final stage of this research is testing the research hypothesis, namely that there is a positive and significant relationship between Linguistic Intelligence and Arabic Vocabulary Mastery. The results showed that, from the calculations in testing the hypothesis, the correlation between the teacher's personality competence and the motivation to learn Arabic has a value of r = 0.761 which is positive. And the correlation between the two variables is at a high value, which is between 0.60 and 0.80. Furthermore, the significant test for an error rate of 5% tcount = 8.92 is greater than ttable = 1.67155, so the null hypothesis is rejected and the alternative hypothesis is accepted. In conclusion, the correlation coefficient between linguistic intelligence and Arabic vocabulary mastery is 0.761, which is significant

Amorphophallus muelleri Blume tuber, which is called porang in Indonesia, is one of the biggest glucomannan sources next to the konjac tuber. Glucomannan is commonly produced by ethanol extraction technique. This study aimed to propose the freeze-thaw cycles (FTC) pre-treatments with two factors including freezing time and the number of cycles before the glucomannan extraction step and investigated the impact on the physicochemical and morphological properties of the extracted glucomannan. The obtained data were statistically tested by means of multivariate analysis of variance (MANOVA) and post-hoc Duncan tests at a significance level (P) of 0.05. The treated samples were statistically compared with the control sample (without FTC) by means of the Dunnett’s test. The result showed that FTC pre-treatments changed the morphology of glucomannan from smooth to become porous globes showing more fissures on its surface. Generally, the freezing time treatments affected the physicochemical properties of glucomannan except for its protein and calcium oxalate contents. The number of cycles did not significantly affect the protein, starch, and calcium oxalate contents. The Dunnett’s test results indicated that the ash, carbohydrate (glucomannan), and color of the glucomannan obtained by the FTC pre-treatments were significantly different from those of the control sample.
Policy tensions in demolition: Dutch social housing and circularity
Authors: Jonker-Hoffrén Paul
Published: July 2023

The circular economy principles in Dutch housing policy are examined through the intersection of national policies in local governance. The performance agreement between municipality, housing corporation and tenant organisations is a central instrument to achieve municipal housing policy objectives. A case study of Rotterdam shows the dominant discourse revolves around notions of social housing oversupply and the benefits of social mix. The policy goal is to achieve ‘balanced neighbourhoods’ by 2030. This discourse is challenged by actors that dismiss social housing oversupply and rather note a social housing shortage. The dominant discourse is also challenged by the financial capacity of housing corporations to create social housing and the effects of policy on their market segment. An emerging second discourse revolves around the role of circular demolition and how it can fulfil goals at the intersection of housing and climate policy. Circularity is shown to be based largely on the inventory of materials resulting from the demolition of social housing. It is framed not only as a solution to reducing emissions but also as a political issue with negative consequences for the social acceptability of climate policies.
Policy relevance
The discourses and challenges identified in this case study show policymaking is based on both framing and facts. The social meaning of circular and social housing policy is different for different actors. In the context of demolition of social housing, the Dutch policy instrument of performance agreements is not ideal for developing participation because it is based on policy decisions that lack tenant involvement. Circular demolition (deconstruction) may impact the situation of many actors. Circular demolition could relieve financial pressure on housing corporations from an investment and building cost perspective, given an otherwise suitable policy environment. However, circular deconstruction could reduce the social acceptability of demolition of social housing if the materials harvested by ‘urban mining’ predominantly come from social housing but do not benefit social housing development. Future policymaking should focus on the interaction between different policy environments and its social and political consequences.

When human beings try to correct the harmful effects of most of their activities on the environment, they tend to make things more complicated. Good management of human activities can produce good results at the environmental level as well as at the economic and social levels. In this case, the management of household wastes is a good example, since from the first contact of suchwaste with the natural environment, its impact on the latter seems very clear; to this end, and with a view to studying the effect of controlled landfills, also known as CET (technical landfill) on vegetation; The Qualitative study and the monitoring of floristic diversity by the application of vegetation indices indicate a significant variability of vegetation of which 30. 5% of the totality of the species inventoried in the old register are new species adapted to this ecosystem of which 13 new species have been inventoried.

At the PJTSAU Department of Soil Science and Agricultural Chemistry, incubation tests were conducted to see how toluene, KNO3 and glucose affect the activity of the soil enzyme L-glutaminase. Toluene has a considerable impact on the activity of L-glutaminase; it lowers enzyme activity in all soils. From 17.19 % to 36.06 %, the percentage drop in activity caused by the addition of toluene was more pronounced in black soils as compared to red soils. For six days, L-glutaminase activity increased in soils that had been incubated with either glucose or glucose-nitrate mixtures. Glucose and nitrate-treated soils were more active than soils that had only been nitrate-treated alone.

It is a known fact that there exist behavioral difficulties among Mathematics students in Estiwani as a result of unresolved attitudinal issues that either the students are not aware of, or that the issues are not properly dealt with. This work seeks to investigate some factors influencing the attitude of secondary school students toward studying Mathematics in the Manzini region. Five schools consisting of two boys-only, two girls-only, and one mixed school were been carefully selected for the investigation. A total of 200 students and 15 qualified teachers were randomly and actively engaged. A combination of the discrete and continuous data collected through observations and using a well-designed questionnaire was carefully analyzed from their graphical representations. It was found that the majority of the students showed a huge gap in the content knowledge and also presented a clear negative attitude towards Mathematics as a subject. Some of the factors responsible for this worrying pattern, as shown by the analysis include poor background from their primary schools, ineffective teaching methods by their teachers, and lack of motivation by their parents among others. Training programs for teachers particularly on the use of technology and teaching aids to better disseminate the contents and the rewards were also highlighted.
