A Consciência Socioambiental para a Psicologia Histórico Cultural e a Educação Ambiental Crítica
Authors: Doro João Lucas Piubeli , Spazziani Maria de Lourdes Spazziani
Published: January 2022

A compreensão da relação sociedade-natureza posta pela Educação Ambiental em virtude da crise ecológica já denunciada desde anos 1950 se acentua com a crise sanitária mundial atual. O entendimento da tomada de consciência na relação dos humanos com o seu entorno natural e cultural contribuem para reflexões acerca do assunto e é primordial para a alteração do status quo estabelecido. Nesse prisma, convém enveredar pelas ideias da Psicologia Histórico-Cultural representada por Lev Semiyonovich Vigotski e pelos pressupostos da Educação Ambiental Crítica, com diversos representantes influenciados pelas ideias de Paulo Freire. Pressupondo que ambas as correntes encontram semelhanças entre si em diferentes cenários, tematizamos a articulação desses referenciais pela importância e pertinência para a formação da consciência. O trabalho não pretende sobrepor ideias e correntes sobre as outras, tampouco findar o assunto proposto nessa temática, mas como o próprio resultado desse trabalho, estabelecer articulações e reflexões sobre a relação homem e natureza, abordando assuntos como consciência socioambiental, o papel social e o sujeito nesses dois campos teóricos.

The authors had to observe a 68-year-old patient suffering from increased sweating, which manifested itself especially sharply during sleep. The patient never had hysterics. seizures, suggestion had no effect on perspiration. The authors make the assumption that sleep is able to cause a change in the composition of the blood and thereby excite the secretory centers in the medulla oblongata.

Amalgamating Bloom’s Taxonomy and Artificial Intelligence to Face the Challenges of Online EFL Learning Amid Post-COVID-19 In Saudi Arabia
Authors: Abalkheel Albatool
Published: January 2022

During the coronavirus pandemic, remote learning offered instructors numerous potential opportunities to implement online applications for the success of students’ language proficiency. Despite this, there has been a rise in the number of challenges that afflicted EFL Saudi instructors and their learners from attaining sustainable development. The core purpose of this work was to explore these complexities and provide suggestions on how Saudi EFL instructors could adapt while maintaining learners’ cognitive and psychological well-being. Furthermore, it questioned the extent to which artificial intelligence (AI) and Bloom’s digital taxonomy (BDT) played an innovative role in improving Saudi educational quality and effectiveness. To this end, a qualitative study design was embraced, consisting of a meta-analysis of the most recent studies conducted on the topic of study. The findings indicated that despite having gained access to platforms and apps led by technology, EFL instructors faced numerous challenges such as inadequate training, incompetence, restricted accessibility, poor web infrastructure, modest technological assistance, low motivation, and attention to deficit learners. Thus, AI and BDT may help bridge the gaps and overcome some of the pandemic's challenges. This study provided recommendations for curriculum designers, developers, and policymakers, on the challenges of e-learning systems and how to address them during the pandemic and afterward.

Wstęp. Mózgowe porażenie dziecięce (MPD) jest zaburzeniem neurologicznym spowodowanym niepostępującym uszkodzeniem ośrodkowego układu nerwowego (OUN) w okresie okołoporodowym lub niemowlęcym. Uszkodzenie OUN nie ma charakteru progresywnego, natomiast powoduje postępujące zmiany zarówno w kontroli nerwowej mięśni, jak i w ich strukturze. Częstym powikłaniem tej niepogłębiającej się patologii OUN są przykurcze mięśniowe. Jedną z teorii wyjaśniającą powstawanie przykurczy jest ograniczona liczba komórek satelitarnych. Są to komórki macierzyste mięśni, odpowiadające za ich wzrost, rozwój i regenerację po urazie. Udowodniono, że u pacjentów z MPD w mięśniu przykurczonym jest o 60-70% mniej komórek satelitarnych niż w mięśniu osób zdrowych. Celem niniejszej pracy jest przedstawienie na podstawie systematycznego przeglądu piśmiennictwa zagadnienia dotyczącego komórek satelitarnych w grupie pacjentów z MPD. Materiał i metody. Przegląd piśmiennictwa został przeprowadzony zgodnie z rekomendacjami PRISMA Statement. Przeszukano medyczną bazę danych MEDLINE/PubMed z wykorzystaniem słów kluczowych: "komórki satelitarne" (ang. satellite cells) w połączeniu z "mózgowe porażenie dziecięce" (ang. cerebral palsy). Wyniki. W latach 2013-2021 zidentyfikowano 10 publikacji spełniających kryteria wyszukiwania, z tego 3 zakwalifikowano do szczegółowej analizy. Zanotowano znacznie mniejszą liczbę komórek satelitarnych w mięśniach, zmniejszoną liczbę włókien mięśniowych w obszarze dla każdej komórki satelitarnej, mniejszą łączną liczbę włókien mięśniowych, obniżenie szybkości tworzenia miotubuli u pacjentów z MPD w porównaniu do mięśni osób zdrowych. Wnioski. Planując proces leczenia i rehabilitacji, zespoły terapeutyczne powinny brać pod uwagę zredukowaną zawartość komórek satelitarnych w mięśniach pacjentów z MPD.
Pore-Scale Numerical Investigations of the Impact of Mineral Dissolution and Transport on the Heterogeneity of Fracture Systems During CO2-Enriched Brine Injection
Authors: You Jiahui , Lee Kyung Jae
Published: January 2022

Carbon dioxide (CO2) storage and sequestration is regarded as an effective approach to mitigate greenhouse gas emissions. While injecting an enormous amount of CO2 into carbonate-rich aquifers, CO2 dissolves in the formation brine under the large pressure and the subsequently formed CO2-enriched brine reacts with the calcite. Reaction-induced changes in pore structure and fracture geometry alter the porosity and permeability, giving rise to the concerns of CO2 storage capacity and security. Especially in the reservoir or aquifer with natural fractures, the fractures provide highly permeable pathways for fluid flow. This study aims to analyze the acid-rock interaction and subsequent permeability evolution in the systems with complex fracture configurations during CO2 injection by implementing a pore-scale Darcy-Brinkman-Stokes (DBS) reactive transport model. The model has been developed by expanding the functionality of OpenFOAM, which is an open-source code for computational fluid dynamics. A series of partial differential equations are discretized by applying the finite volume method and then solved sequentially. Different fracture configurations, such as fracture length, density, connection, and mineral components, have been considered to investigate their impacts on the dynamic porosity-permeability relationship, dissolution rate, and reactant transport characteristics during CO2 storage. Various mineralogical compositions were investigated to compare their effects on the reactive transport and subsequent system behavior induced by water-rock interactions. The investigation revealed several interesting findings. We found that calcium (Ca) ions concentration was low in the poorly connected area at the initial time. Because CO2-enriched brine saturated the system and reacted with calcite, Ca ions started accumulating in the system. However, Ca ions barely flowed out of the poorly connected area, and the concentration became high. Lengths of branches mainly influenced the dissolution rates, while they had slight impacts on the porosity-permeability relationship. While fracture connectivity had an apparent influence on the porosity-permeability relationship, it showed a weak relevance on the dissolution rate. The calcite-clay fracture-matrix system showed a slow increase of permeability because CO2-enriched brine was injected. These microscopic insights can help enhance the CO2 sealing capacity to guarantee environmental safety.
A balanced watershed decomposition method for rain-on-grid simulations in HEC-RAS
Authors: Hariri Sleimane , Weill Sylvain , Gustedt Jens , Charpentier Isabelle
Published: January 2022

Rain-on-grid simulations for the modeling of 2D unsteady flows in response to precipitation input are implemented in Hydrologic Engineering Center's River Analysis System (HEC-RAS) software by means of a finite volume method and a sparse parallel linear solver running on a unique processor. Obviously, this may fail due to memory shortage when the discretization yields too large linear systems. Such simulations are good candidates for the design of partition and domain decomposition methods for the modeling of very large catchments by means of hydrological sub-units. Thinking in load-balanced computations, the proposed area-balanced partition method is based on the flow accumulation information. Implemented in HEC-RAS, the domain decomposition method comprises 2D–1D models combining 2D sub-unit meshes to 1D channels for extracting outflow data from upstream units and passing the information to downstream units. The workflow is automated using the HEC-RAS Controller. As a case study, we consider the French Saar catchment (1,747 km2). The new partition methods demonstrate a better equilibrium for sub-basin areas and the computational load for the sub-problems. The total computational time is substantially reduced. Domain decomposition is required for carrying rain-on-grid simulations over the Saar watershed (2,800,000 elements). The resulting discharge and flood maps show very good agreements with available data.
Research on water resources pricing model under the water resources–economic high-quality development coupling system: a case study of Hubei Province, China
Authors: Li Jia-Wen , Wu Zheng , Tian Gui-Liang
Published: January 2022

Achieving high-quality economic development under the new development pattern has become an inevitable requirement for China's economic development. Correctly calculating the value of water resources and optimizing the price mechanism of water resources is one of the important guarantees for promoting the high-quality development of the regional economy. Based on this fact, this paper takes Hubei Province as an example to construct a coupling relationship model between water resources and economic high-quality development and to evaluate the coupling coordination between the two. And then, the fuzzy comprehensive evaluation model is used to evaluate the value of water resources in Hubei Province, and recalculate its water price. The results show that Hubei province now is a lagging development of water resources, and the current water price is far lower than assessed. The government should improve the mechanism of water price which should be driven by innovation to adjust the water use structure, finally achieve high-quality economic development of Hubei Province.

Authors: Yang Xing , Pu Yongwei , Weng Songgan , Hou Miao , Wang Zhihuan
Published: January 2022

The scarcity of water resources has posed serious threats to the sustainable development of agriculture. China is a largely agricultural country with a large population, and agricultural water consumption accounts for more than 50% of the total water consumption. The application of water-saving irrigation is the main way to realize the sustainable development of water resources and economics. To comprehensively improve crop water-use efficiency and reduce agricultural water consumption, the Chinese central government have promulgated a series of agricultural water-saving policies since 2012, such as strengthening water management, increasing financial investment, and strengthening project construction and operation management and protection. Taking Jiangsu as an example, this paper reviews the main water-saving policies and measures of governments after 2012, as well as the conflicting interest between different water-saving participants. Results showed that, through water-saving policies and measures, its effective utilization coefficient of agricultural irrigation water (EUCAIW) has increased from 0.59 in 2014 to 0.614 in 2019. By 2019, the area of irrigated arable land controlled by water-saving technologies is 2.848 million hectares, accounting for 67.8% of the irrigated arable land area in Jiangsu. Jiangsu's water-saving policies have been implemented well, and it has guidance on water-saving reform work in other places.
Effects of electroflocculation/oxidation pretreatment on the fouling characteristics of ultrafiltration membranes
Authors: Li Yinghua , Wang Yiyan , Liao Mengxi , Su Fei , Zhang Yue , Peng Linlin
Published: January 2022

In order to reduce the membrane pollution of ultrafiltration caused by natural organic matter and improve the treatment efficiency, electroflocculation/oxidation is used as the premembrane treatment method. The membrane specific flux attenuation characteristics was compared and analyzed under the conditions of direct ultrafiltration and electroflocculation/oxidation-ultrafiltration. Combined with the analysis of the reversibility of membrane fouling, the mechanism of electroflocculation/oxidation pretreatment to alleviate ultrafiltration membrane fouling was evaluated, and the membrane pore clogging model was used to fit the fouling law. The results show that, in the continuously fed filtration experiment, the electroflocculation/oxidation process involved in the pretreatment and the direct ultrafiltration membrane filtration decreased the ultrafiltration membrane flux to 79.1% and 28.5%, respectively. The reversible resistance generated by ultrafiltration and electroflocculation/oxidation-ultrafiltration processes accounted for 37.70% and 62.26% of their total pollution resistance, whereas the irreversible resistance generated accounted for 47.30% and 12.40%, respectively. Meanwhile, the direct correlation between the the flux dropped and complete clogging became less than that of the ultrafiltration process. The pretreatment significantly strengthened irreversible fouling resistance of the membrane pores. The membrane permeation flux was significantly increased after the electroflocculation/oxidation pretreatment.

density, infinite in both direction, undergoing longitudinal vibrations
under the action of an external load, and a stress-strain relationship
using a fractional order differentiation operator with respect to the
time variable. We use three types of fractional operators, two
non-singular, one with exponential kernel and Mittag-Leffler type
kernel. And a singular one with power-law type kernel. We analyze some
initial and boundary value problems resulting from the modeling of the
aforementioned wave processes in viscoelastic media, using some recent
proposals for fractional order derivatives. The fundamental solution of
these problems is established, and its moments are calculated.

Authors: Mendes Júnior Sérgio , de Oliveira Deyvis Kolodziyczyk , Lemos Andreia Regina Boff , de Freitas Karina Maria Salvatore , Valarelli Fabrício Pinelli
Published: January 2022

Class II maloclusion is highly incident on the population and is difficult to treat. There are several protocols for its correction such as: extractions, use of elastics and functional appliances. Some factors have to be considered during the diagnosis in order to reach an assertive treatment plan and not to bring harm to the patients. Premolar extractions is an effective and efficient way, but it can bring undesirable alterations to the facial profile. In this context orthodontists can make use of more conservative options. When elastics are used, the treatment success depends largely on patient compliance. If the patient is non-compliant, the sagittal correction and the treatment as a whole end up being compromised. On the other hand, fixed functional appliances are a favorable option to the Class II correction, because it does not depend on patient compliance and are relatively comfortable. The aim of this article is to present a clinical case of a bilateral Class II with mandibular retrusion treated with the fixed functional appliance Forsus. The treatment was performed without extractions in order to avoid the retraction of the superior lip and increase the protrusion of the inferior lip, improving the patient’s profile and consequently her self-esteem. This appliance proved to be efficient promoting predominantly higher dentoalveolar changes. Being a relatively comfortable appliance, it was well accepted by the patient who cooperated and was adept to this treatment modality. It was concluded that the fixed functional appliance Forsus is effective to correct Class II.

The Great Power of Prediction from a Massive Photon Hypothesis.
Authors: CORNIERE Henri
Published: January 2022

Mass, an inherent property of matter, is calculated directly for the photon particle from the very classical principles of the kinetic theory of gases. That concept of photon mass is nearly as old as physics itself and in fact nothing prevents this approach to be carried out for a so-called quantum particle, not even its minute size. It is not an end result with no perspective nor other outcome.  Quite the opposite, a single ponderable tiny photon frees the mind of old ways of thinking and opens up new paths to a broad field of investigation where the very large can then be  described and explained by the very small. This reality of a non-zero mass suddenly shows up in the interpretation of many experiments which become clear and simple to comprehend. Besides, that same key particle has the potential to unlock and solve some long lasting major observational issues or enigmas. All this converges upon its acknowledgment and acceptance.
Mass, an inherent property of matter, is calculated directly for the photon particle from the very classical principles of the kinetic theory of gases. That concept of photon mass is nearly as old as physics itself and in fact nothing prevents this approach to be carried out for a so-called quantum particle, not even its minute size. It is not an end result with no perspective nor other outcome.  Quite the opposite, a single ponderable tiny photon frees the mind of old ways of thinking and opens up new paths to a broad field of investigation where the very large can then be  described and explained by the very small. This reality of a non-zero mass suddenly shows up in the interpretation of many experiments which become clear and simple to comprehend. Besides, that same key particle has the potential to unlock and solve some long lasting major observational issues or enigmas. All this converges upon its acknowledgment and acceptance.

Mangga Kasturi (Mangifera casturi Kosterm) merupakan mangga endemik Kalimantan Selatan dengan status langka di alamnya berdasarkan IUCN-red list. Kasturi dengan masa juvenil yang panjang sehingga menyebabkan awal pembuahan yang lama. Penggunaan cahaya buatan dengan lampu LED-light emmiting diode diketahui dapat memperpendek juvenilitas karena meningkatkan efisiensi fotosintesis. Penelitian ini bertujuan untuk mempelajari perbedaan respon fisiologi dari bibit mangga Kasturi menggunakan lampu LED. Penelitian ini menggunakan rancangan petak tersarang dengan faktor utama lampu LED dan faktor kedua aksesi sebagai perlakuan yang disarangkan. Faktor utama terdiri dari tiga taraf yaitu LED merah, putih dan biru, sedangkan faktor kedua terdapat tiga taraf yaitu aksesi Cuban, Pelipisan, dan Kasturi. Penggunaan LED memberikan beberapa perbedaan respon terhadap kandungan klorofil, LED merah menunjukan nilai paling tinggi pada kandungan klorofil a, tetapi tidak ada pengaruh pada klorofil b dan rasio klorofil. Penyinaran LED biru menunjukkan nilai absorsi cahaya, konduktansi stomata, transpirasi, dan laju fotosintesis yang lebih tinggi pada aksesi Kasturi. Lampu LED biru meningkatkan kandungan glukosa, sedangkan lampu LED putih membuat kandungan fruktosa yang lebih tinggi dibandingkan lampu lain dan mempengaruhi ketebalan daun yang lebih tebal. Berdasarkan penelitian ini monokromatik LED memberikan pengaruh berbeda pada setiap karakter fisiologis, yang berpengaruh pada percepatan masa juvenil.

Kerontokan buah sering terjadi dan menyebabkan rendahnya panen buah. Informasi penggunaan hormon GA3 dalam menekan kerontokan buah pada jeruk pamelo masih belum tersedia. Riset ini bertujuan untuk mengkaji peranan GA3 terhadap kerontokan dan kualitas buah jeruk pamelo berbiji dan tidak berbiji. Penelitian ini dilaksanakan pada Desember 2019 sampai Juni 2020 di Desa Tambakmas, Kecamatan Sukomoro Kabupaten Magetan. Desain percobaan menggunakan rancangan tersarang, dimana faktor utama adalah kultivar (Bali Merah 1 dan Bali Merah 2) dan faktor tersarang adalah penyemprotan GA3 (tanpa disemprot GA3, penyemprotan GA3 pada 1 minggu setelah antesis (MSA) dan penyemprotan GA3 pada 1 dan 3 MSA). Bali Merah 1 tergolong pada pamelo berbiji, sedangkan Bali Merah 2 adalah pamelo tidak berbiji. Peubah pengamatan meliputi konsentrasi GA3 buah pada 4, 5, dan 6 MSA, final set, jumlah buah rontok, bobot dan diameter buah, bagian dapat dimakan (BDD), padatan terlarut total (PTT), asam tertitrasi total (ATT), rasio PTT/ATT dan vitamin C. Hasil menunjukkan bahwa penyemprotan GA3 meningkatkan final set namun tidak memberikan pengaruh nyata pada bobot buah, diameter buah, ATT, rasio PTT/ATT dan kandungan vitamin C. Penyemprotan GA3 pada 1 dan 3 MSA menekan jumlah buah rontok serta meningkatkan konsentrasi GA3 buah pada 4, 5, dan 6 MSA, BDD dan PTT buah.

Authors: Kiran H. S. , Rajani H. S. , Rashmi N. , Gowdappa H. Basavana
Published: January 2022

Objectives:

The COVID-19 pandemic with its peaks and lockdowns has resulted in an unprecedented situation. Medical postgraduate (PG) residents were the “frontline COVID warriors” involved in direct patient care including COVID patients in many medical institutions across India. While the perceptions of undergraduate-MBBS students have been assessed, there are few studies assessing the perceptions of medical PG students in India during the COVID-19 pandemic. The objective of this study was to assess the perceptions of medical PG students during the COVID-19 pandemic in general including online teaching

Material and Methods:

The survey-based study was conducted using a pre-tested online questionnaire during the peak periods of COVID-19 outbreak in India including both the first and second waves. A cross-sectional internet-based online survey in the form of a questionnaire was prepared using Google Forms, and the responses were collected from the respondents. All respondents were from various places in South India.

Results:

A total number of participants were 135 across South India. All were involved in direct care of COVID patients. This study shows that many PGs were stressed, anxious, and worried but nearly 69% rated their overall sleep quality as “good.” Nearly, 75% reported that they “miss regular practical/bedside classes” while nearly 61% reported that they “miss regular seminar classes.”

Conclusion:

The unprecedented COVID-19 pandemic has impact on medical PG residents in training both in terms of psychological aspects and their education as well. This study highlights the perceptions of PG students during the COVID-19 pandemic and hints at possible indications of resilience and intact coping mechanisms among PG students and the inevitability of online teaching during this unprecedented situation.
