Authors: Nurdin Iin Nurdiyanty
Published: July 2024

Penanganan pascapanen rumput laut seringkali diabaikan sementara mutu bahan baku pascapanen menjadi salah satu bagian yang menentukan kualitas dari produk akhir. Penelitian ini bertujuan untuk mengkaji proses penanganan pasca panen rumput laut Eucheuma cottonii di Kabupaten Buton Tengah Sulawesi Tenggara. Penelitian dilakukan dengan metode survey dengan mewawancarai pembudidaya dan pengumpul rumput laut. Analisis data dilakukan secara deskriptif kualitatif. Hasil penelitian menunjukkan bahwa penanganan pascapanen terhadap perbaikan mutu ditingkat petani dan pedagang pengumpul masih kurang diperhatikan dari prosedur penggunaan peralatan, penimbangan, pengemasan, pelabelan dan penyimpanan (penggudangan). Metode pengeringan yang digunakan sudah sesuai dengan Standar Nasional Indonesia. Rendahnya kualitas pasca panen salah satunya disebabkan pemahaman petani yang masih rendah terkait pentingnya penanganan rumput laut terhadap harga dan kualitas produk akhir yang dihasilkan.  Oleh karena itu diperlukan peran sub sistem penunjang untuk dapat memberikan input edukasi pada sub sistem hulu ditingkat petani dan sub sistem penanganan dan pengolahan rumput laut.

Published: July 2024

The high cost of commercially available butter for bread production in developing countries is increasing bread prices but, in West Africa shearbutter which is a cheap vegetable fat has less utilization. Therefore, this study aimed to evaluate the effects of its addition on bread production. Shea butter (Raw and deodorized) were added to bread dough at 15, 20, 25 and 30 g and 20g of margarine added to bread dough served as a control sample. The proximate composition, peroxide value and free fatty acid of the bread samples were determined and sensory acceptability of bread samples were determined by 25-member panelist. The percentages of crude protein, moisture, crude ash, crude fat, crude fibre and carbohydrate contents of the bread samples ranged as 13.77 – 28.89, 28.13 – 31, 0.83 – 1.83, 1.89 – 3.62, 0.27 – 0.85 and 34.26 – 53.45%, respectively. The peroxide value and free fatty acid ranged as 7.00 – 14.27 meq/kg and 0.075 – 0.132%, respectively. Shea butter inclusion led to a significant increase in crude protein, ash and crude fat contents and significant difference in all the sensory parameters evaluated. However, acceptability rating showed that addition up to 25g of raw or deodorized Shea butter could be acceptable.
Exploring The Morphological Diversity Of Selected Abakaliki Local Rice Cultivars: A Study Of Key Physical Traits And Variations
Authors: Onwuchekwa Ogah
Published: July 2024

Abakaliki rice is unique compared to other rice grown in different parts of Nigeria, unfortunately, rice yield per hectare is low because smallholder farmers rely on local rice cultivars with low yield potentials, Therefore, identification of high-yielding locally adapted rice varieties in combination with high grain quality is the most effective strategy in increasing rice production in Ebonyi State. Hence, forty rice cultivars collected from different villages and local government areas in Ebonyi State were cultivated in a complete randomized block design in three replications to evaluate the morphological characteristics of the Abakaliki local rice cultivars using the standard rice evaluation method. The results showed that Nwangbashianya had the highest grain length with a mean value of 1.03mm followed by Akuje and Iron with the same mean value of 1.00 mm,. Mars had the maximum plant length with a mean value of 174.67cm, and maximum performance for 1000 grain per weight with a mean value of 4.13kg. The results also revealed varied number of primary panicles for which Iron recorded the highest mean value of 43.67. The maximum number of primary and secondary tillers were observed in Faro 15 and Offia with mean values of 6.33 and 4.00 respectively. Concurrent selection based on these best-performing cultivars with exceptional traits could lead to the development of high-yielding rice varieties in Ebonyi State.

Students' Interpretations of Quantum Mechanics Concepts from Feynman's Sum of all Paths Applied to Light
Authors: Fanaro Maria de los Angeles , Arlego Marcelo Jose Fabian , Otero Maria Rita , Elgue Mariana
Published: July 2024

We analyse part of the implementation of a didactic sequence to teach different aspects of light in a unified non traditional framework. The goal was to propose the quantum theory of light as a universal framework to describe different phenomena observed. The laws of quantum mechanics for light using Feynman´s “Sum of all Paths” approach adapted to the mathematical level of the students was proposed as a model to explain the experiences. This particular denomination of Feynman´s approach is an intentional choice to avoid the language of "integral" because the students haven't had calculus. Graphic representations and basic operations with vectors capturing the essential aspects of the theory, were used. Simulations made with the software GeoGebra(R) and Modellus were created to help students visualize the formulation. The sequence was carried out in four courses (aged 15-16). For the data analysis, an answer categorization was formulated, considering among other aspects the quantum reformulation of experiment shown herein. This analysis seeks to understand the student´s conceptualization process about quantum interpretation. The results support the conclusion that the conceptualization is complex, and slow, due to both the concepts involved and the representation systems demanded by the situations.
Writing in Physics Classes in High School: Possibilities
Authors: Setlik Joselaine , Higa Ivanilda
Published: July 2024

This work explores the potentiality of writing in Physics classes by means of a didactic proposal developed in High School in Brazil, which consisted of inserting writing as a means of establishing relations of sense. It were adopted elements from Vygotsky theories (1978; 1986), assuming the importance of written language in learning process and the need for intrinsic motivation for learning; and Bakhtin theories (1986), defending language as essentially dialogical.The proposal consisted of reading texts about the history of Electromagnetism, followed by questions, and writing a letter to a scientist. Interviews were conducted with some students to understand the sense they attributed to the activity. The analysis permitted to argue in favor of writing potentiality in the learning and development processes. This experience indicates relevant discussions in favor of adopting writing activities as part of Physics teaching and learning processes.
Permanent Education and the Integration of Digital Information and Communication Technology in Physics Education in Santa Catarina
Authors: Leonel André Ary , Angotti José André Peres
Published: July 2024

Educating Physics teachers has shown to be a great challenge. The present work is part of a bigger study that has had as its central axis two demands related to the education of these professionals: the first one refers to social changes brought about by the Digital Information and Communication Technologies (DICT), which require a (re)signification of the school and of the teacher’s profile; and the second relates to the great percentage of teachers working in the field without the qualifications that the profession requires. The focus here will be the process of integrating the DICT in the practices of the Physics teachers who participated in a continuing education course that was planned and developed during the research. It can be inferred that the development of the activities and discussions about the pedagogical practices conducted during the course resulted in the comprehension around the critical and creative use of the DICT. However, it is important to keep in mind that such an integration constitutes a slow and gradual process.

Authors: Mota Ana Rita , Dos Santos João B. Lopes , Esperto Paula , Coutinho Isabel
Published: July 2024

There is an increasing interest in peer and self-assessment (P&SA) in science education due its importance in students’ performance in collaborative work and in the development of their metacognitive skills. We developed and tested an algorithm to help teachers organize the P&SA process. Collected data relative to the 8th and 11th grades were analyzed to examine the viability of this algorithm and to determine the degree of agreement between a student’s self-assessment and that of his/her peers. We found no significant differences between peer and self-assessment, which means that students have a fair perception of their contribution to the team. The data also suggest that the maturity of the students can be an important variable in the self-regulation learning and in metacognitive skills acquisition, since the correlation between self and peer assessment was more robust in the 11th grade.

Authors: Wolf Kai , Bach Anna-Maria , Waitz Thomas
Published: July 2024

In the present qualitative study we identified different types of students’ mass media reception on topics related to chemistry. 19 secondary school students participated in guided interviews concerning their overall encounter with chemistry in the mass media. The collected data was analyzed referring to Grounded Theory by an open and axial coding procedure. The evaluation is based on four categories including context, social condition, cause and consequence of media reception. For analysis, a special focus was placed on the development of interest with respect to media reception. In total, four types of media reception like "The News Focused" or "The Effect Focused" were identified. The guided interviews showed that students are interested in a large variety of chemical topics present in media. Due to this, a strong individualization of chemistry related media reception can be concluded. Finally, it will be shown that the results of this study are relevant for revising teaching materials in order to create individualized and motivating learning tasks.

Published: July 2024

The article widely uses logical, inductive, deductive, systematic, logical-legal, and comparative-legal research methods. In particular, first of all, the concept of inaction in criminal law and its objective and subjective criteria are described in detail. The scientific views and studies of scientists on a socially dangerous act committed in criminal law and the similarities and differences between them are described in detail. The presence of two types of criminal inaction as a form of socially dangerous act in criminal law, consisting of pure and mixed inaction, as well as the existence of problematic moments in the qualification of crimes committed in mixed inaction, is proved. A comparative analysis of the legal nature of mixed inaction as a type of socially dangerous inaction was also carried out, and its general and special features and problematic aspects were also identified and consistently described. In criminal law, mixed inaction consists of a socially dangerous act consisting of a combination of specific actions and inactions, and its criminal legal aspects are revealed. This article focuses on socially dangerous inaction, both instrumentally and comparatively, and analyzes its criteria and features. The main conditions of this sign are determined, and their theoretical and practical solutions are established and found. At the same time, the doctrine of criminal law and existing scientific research were analyzed, and reasonable theoretical proposals and recommendations were developed in this regard.

A exposição ao bisfenol A (BPA) tem sido uma preocupação crescente devido aos seus potenciais efeitos adversos na saúde, especialmente em crianças. Esta revisão abrangente teve como objetivo avaliar os efeitos da exposição ao BPA em crianças, abordando aspectos biológicos, mecanismos de ação, vias de exposição, níveis de exposição populacional e estratégias de mitigação. A busca sistemática identificou 15 estudos relevantes, que abordaram uma variedade de desfechos relacionados aos efeitos do BPA em crianças. Os resultados indicaram que a exposição ao BPA está associada a uma série de efeitos biológicos adversos, incluindo distúrbios endócrinos, metabólicos, neurocomportamentais e imunológicos. Os mecanismos de ação do BPA envolvem a ativação de receptores estrogênicos e não estrogênicos, resultando em desregulação hormonal, danos celulares e estresse oxidativo. As principais vias de exposição ao BPA em crianças são a ingestão de alimentos e líquidos contaminados por embalagens plásticas e a exposição a produtos de consumo cotidiano. Estudos de biomonitoramento mostraram que a maioria das crianças apresenta níveis detectáveis de BPA na urina, refletindo uma exposição generalizada. Estratégias de mitigação, como a redução do uso de plásticos contendo BPA e a melhoria da rotulagem de produtos, foram propostas para reduzir a exposição das crianças a esse composto. No entanto, ainda há lacunas no conhecimento, destacando a necessidade de pesquisas adicionais para entender melhor os efeitos a longo prazo da exposição ao BPA em crianças e desenvolver estratégias eficazes de prevenção. Em conclusão, a exposição ao BPA representa um desafio significativo para a saúde infantil, e a implementação de políticas de saúde pública e intervenções eficazes é crucial para proteger as crianças contra os efeitos adversos desse composto.

A amputação é a remoção cirúrgica total ou parcial de um membro, geralmente necessária em casos de doenças avançadas como Diabetes Mellitus, doença vascular periférica, tumores malignos, traumas e infecções, afetando significativamente a vida dos pacientes. A incidência varia de 1.2 a 4.4 por 10.000 habitantes, com mais de 90% das amputações ocorrendo nos membros inferiores, número que pode dobrar até 2050. A preservação da articulação do joelho é crucial para a reabilitação, sendo a amputação transtibial a mais comum. A osteomielite crônica é uma infecção persistente do tecido ósseo, representando um desafio devido à limitada penetração de antibióticos em áreas avasculares, com taxas de recorrência entre 20% e 30%. Cerca de 23% dos pacientes mantêm infecções mesmo após três cirurgias, tornando a amputação, às vezes, a melhor opção. Cotos mal-acabados podem causar complicações e dificultar a adaptação à prótese ortopédica, essencial para o controle durante o ortostatismo e a deambulação. A amputação transtibial ocorre entre a desarticulação tibiotársica e a articulação do joelho, classificada em três níveis: terço proximal, médio e distal.

As complicações pós-operatórias em cirurgias abdominais são uma preocupação significativa na prática cirúrgica, impactando diretamente os desfechos clínicos dos pacientes e aumentando os custos hospitalares. Esta revisão integrativa teve como objetivo identificar os principais fatores de risco e as estratégias de prevenção para complicações pós-operatórias em cirurgias abdominais, com base na literatura científica publicada entre 2013 e 2023. Os fatores de risco identificados incluem características do paciente, como idade avançada, presença de comorbidades (diabetes, hipertensão, insuficiência renal e doenças cardiovasculares), estado nutricional comprometido e status imunológico debilitado. Fatores relacionados à cirurgia, como complexidade e duração do procedimento, tipo de cirurgia (emergência versus eletiva) e técnica cirúrgica (aberta versus minimamente invasiva), também foram destacados. Além disso, fatores ambientais, como a eficácia dos protocolos de controle de infecção e a capacitação da equipe médica, mostraram-se críticos para os desfechos pós-operatórios. As estratégias de prevenção mais eficazes incluíram a implementação de rigorosos protocolos de controle de infecção, monitorização intensiva no período perioperatório, intervenções nutricionais pré-operatórias, educação contínua e treinamento da equipe de saúde, e a adoção de técnicas cirúrgicas minimamente invasivas. A aplicação dessas estratégias foi associada a uma redução significativa na incidência de complicações pós-operatórias. A revisão destaca a importância de uma abordagem multidisciplinar e personalizada na prevenção das complicações pós-operatórias, enfatizando a necessidade de estratificação de risco dos pacientes e a implementação de medidas preventivas direcionadas. Além disso, sublinha a necessidade de pesquisas futuras para validar as estratégias identificadas e explorar novas abordagens, incluindo a integração de tecnologias emergentes como inteligência artificial e análise preditiva. Em conclusão, a prevenção das complicações pós-operatórias em cirurgias abdominais requer uma compreensão detalhada dos fatores de risco e a implementação de estratégias de prevenção baseadas em evidências. A colaboração multidisciplinar, a educação contínua e a inovação tecnológica são essenciais para melhorar a segurança e a eficácia dos cuidados cirúrgicos, beneficiando tanto os pacientes quanto o sistema de saúde como um todo.
The role of interfacial tension in the size-dependent phase separation of atmospheric aerosol particles
Authors: Schmedding Ryan , Zuend Andreas
Published: July 2024

Abstract. Atmospheric aerosol particles span orders of magnitude in size. In ultrafine particles, the energetic contributions of surfaces and interfaces to the Gibbs energy become significant and increase in importance as particle diameter decreases. For these particles, the thermodynamic equilibrium state depends on size, composition, and temperature. Various aerosol systems have been observed to undergo liquid–liquid phase separation (LLPS), impacting equilibrium gas–particle partitioning, modifying physicochemical properties of the particle phases, and influencing cloud droplet activation. Numerous laboratory experiments have characterized the onset relative humidity of LLPS in larger aerosol particles and macroscopic bulk systems. However, in sufficiently small particles, the interfacial tension between two liquid phases constitutes an energetic barrier that may prevent the formation of an additional liquid phase. Determining said small-size limit is a key question. We introduce a predictive droplet model based on the Aerosol Inorganic–Organic Mixtures Functional groups Activity Coefficients model. This model enables size-dependent computations of surface and interfacial tension effects on bulk–surface partitioning within phase-separated and single-phase particles. We evaluate four approaches for computing interfacial tension in multicomponent droplets, including a new method introduced in this work. Of the approaches tested, Antonov's rule best matches observed liquid–liquid interfacial tensions in highly immiscible mixtures, while a modified Butler equation fits well in more miscible systems. We find that two approaches substantially lower the onset relative humidity of LLPS for the studied systems.
A physically based statistical model with the parameterized topographic effect for predicting the weakening of tropical cyclones after landfall over China
Authors: Liu Lu , Wang Yuqing
Published: July 2024

Accurate prediction of tropical cyclone (TC) intensity is important but challenging. Previous exponential decay models of TC weakening after landfall assume the TC weakening rate after landfall being proportional to TC intensity at the time of landfall. In this study, a physically based algebraic decay model with topographic effect for predicting TC weakening after landfall over mainland China is constructed based on the best-track TC data during 1980–2020. In this model, the TC weakening rate is proportional to the square of the TC maximum near-surface wind speed with the “effective” surface drag coefficient being an internal parameter. The topographic enhancement of surface drag coefficient is introduced to include the topographically enhanced TC weakening over the southeastern coastal region of mainland China. This is achieved by parameterizing the drag coefficient as a linear function of the normalized topographic height in the study domain, which is calibrated by minimizing the forecast errors for all landfalling TCs over mainland China during 1980–2020. Different from most decay models discussed in previous studies, the algebraic decay model that we have developed in this study is a time-dependent decay parameter along the TC track due to the topographic variation. Results show that the previous decay models underestimated the weakening rate enhanced by topographic effect over the southeastern China while overestimated the weakening rate of TCs after landfall over the eastern China where plains are dominated. The algebraic decay model with the introduced parameterized topographic effect shows considerably better performance. Thus, the algebraic decay model with topographic effect considered performs better than the commonly used exponential decay model for TCs after landfall over mainland China, especially when TCs move further inland. 
Chaos, Coupling and Climate: The Oceanic Pathway to Atmospheric Blocking

After establishing the link between Gulf Stream heat transport and subsequent atmospheric blocking in Mathews and Czaja (2024), revealing nearly double the amount of blocking over Greenland during DJF following increased heat transport through the Florida Straits in late summer, and confirming this connection using the ECMWF IFS in Mathews et al. (2024)—where surface latent heat fluxes over the Gulf Stream were suppressed, resulting in a reduction of blocking by up to 30% across the entire northern hemisphere, attributed to the diminished transport of boundary layer air into the upper troposphere along warm conveyor belts—we now adopt a playful exploration of this mechanism through a heuristic model.This simple three-box model connects a basic slab ocean to an atmospheric boundary layer via heat fluxes, which then connects to the upper troposphere through slantwise convection following Emanuel (1983). Mimicking real-world dynamics, the model shows increased (decreased) ocean heat content before (after) an atmospheric block. Additionally, convection is triggered only when negative potential vorticity is present in the atmospheric boundary layer as theorised by Bennetts and Hoskins (1973).  By adjusting various feedback parameters the system bifurcates, leading to a series of period doublings before entering a chaotic regime. By utilising the instantaneous dynamical systems properties of the attractor as described by Faranda et al. (2017), we infer the predictability of the system with different arrangements of control parameters.This simple model underscores the importance of accurately representing the oceanic pathway to atmospheric blocking in more sophisticated climate models for precise predictions of how atmospheric blocking changes in a warmer climate.
