Com a palavra, o usuário com deficiência e a realidade vivenciada nas bibliotecas
Authors: Wellichan Danielle da Silva Pinheiro , Manzini Eduardo José
Published: May 2023

O usuário pode ser considerado uma fonte de informação importante para as bibliotecas no que diz respeito à elaboração e ao direcionamento de produtos e serviços desenvolvidos para ele, principalmente se for uma pessoa com deficiência. No entanto, apesar da recomendação e orientação na literatura, esse usuário ainda não é atendido como esperado no que se refere ao acesso e acessibilidade na biblioteca. Sob essa perspectiva, objetivou-se conhecer, junto a nove usuários com deficiência, a relação entre eles e as bibliotecas, desde a infância até a fase atual, e como, na visão deles, os profissionais da biblioteca poderiam oferecer atendimentos mais inclusivos. Como um estudo de usuários, buscou-se a construção do presente texto por meio de um referencial teórico que reuniu materiais em língua portuguesa, sem recorte temporal, associados à gravação de vídeos realizada pelos próprios usuários convidados. Os resultados apontaram duas situações em uma mesma realidade: de um lado, usuários que encontraram, nas bibliotecas escolares, apoio para seu desenvolvimento; por outro lado, os que a conheceram apenas no Ensino Superior, momento em que se unem ao apontar que a biblioteca universitária oferece melhores condições de uso e frequência, mesmo em meio a algumas dificuldades. O estudo permitiu concluir que essa relação pode ser satisfatória em diversos pontos, principalmente se o usuário da informação for ouvido e colaborar em seu processo inclusivo nas bibliotecas.
São Jeronimo nos trópicos: o un savant travaillant dans son cabinet de Debret
Authors:   Universidade Estadual de Campinas, Morato Fernando
Published: May 2023

Este trabalho começa com uma curiosidade de minha parte: trabalhando há alguns anos com a obra do poeta neoclássico brasileiro Manuel Inácio da Silva Alvarenga, de quem não existe nenhum retrato, deparei-me com a imagem do Un savant travaillant dans son cabinet de Jean-Baptiste Debret na capa do primeiro volume da História da vida privada no Brasil e achei que ela casava bastante bem com a situação que deveria ser vivida pelo poeta, idealizador da Sociedade Literária do Rio de Janeiro (na qual se leram algumas memórias científicas), dono de um pequeno museu em sua casa e da maior biblioteca privada do país.

Published: May 2023

A alimentação escolar é um direito constitucional assegurado a todos os estudantes matriculados na rede pública de educação básica no país, sendo a principal forma de realizar essa garantia através do Programa Nacional de Alimentação Escolar (PNAE), um dos mais antigos programas de alimentação e nutrição no Brasil, com magnitude e pioneirismo reconhecidos internacionalmente. Objetiva-se avaliar a adequação da alimentação escolar oferecida pelo PNAE, assim como o estado nutricional de estudantes da rede pública do município de Macaé. Trata-se de uma pesquisa transversal, com abordagem quantitativa, desenvolvida em escolas do ensino fundamental no município de Macaé. Para avaliação da alimentação escolar utilizou-se o método da pesagem direta de alimentos nas escolas, e o estado nutricional foi avaliado a partir dos índices estatura para idade e índice de massa corporal para idade. Foi observado excesso na oferta de macronutrientes nas escolas avaliadas e insuficiente oferta de micronutrientes, como cálcio e vitamina A. Concluiu-se que sobrepeso e obesidade estiveram presentes em quase 40% das 435 crianças avaliadas, nos permitindo entender a importância da alimentação escolar para promoção de hábitos alimentares saudáveis e prevenção de doenças crônicas.

Treatment strategy after the discontinuation of immunotherapy for head and neck cancer: a review
Authors: Wakasugi Tetsuro
Published: May 2023

First-line systemic therapy with immune checkpoint inhibitors (ICIs) is currently the mainstream treatment for recurrent or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) that is not amenable to local therapy. However, the optimal treatment after discontinuation of ICIs is still unknown, and no large-scale analysis has been conducted in R/M SCCHN. In this narrative review, we summarize the treatment strategies available to continue ICI therapy using the currently available treatment modalities. After the administration of ICIs, unlike cytotoxic agents, the following responses are observed: durable response, pseudo-progressive disease, hyper-progressive disease, mixed response, immune-related adverse events (irAEs), and improved sensitivity to subsequent chemotherapy. Some patients show a durable response to ICIs and a good prognosis; however, many patients will require salvage therapy. We need to select the subsequent treatment according to the various responses unique to ICIs to obtain a durable response. For instance, there are reports on the effectiveness of reapplication of local therapy for a mixed response, retreatment with ICIs, and off-treatment in responsive cases complicated by irAEs. If a durable response can be maintained with ICI therapy, a long-term prognosis that cannot be obtained with conventional chemotherapy can be achieved.
The Geometrization of Maxwell’s Equations and the Emergence of Gravity
Authors: Beach Raymond
Published: May 2023

Coupling the Maxwell tensor to the Riemann-Christoffel curvature tensor is shown to lead to a geometricized theory of electrodynamics. While this geometricized theory leads directly to the classical Maxwell equations, it also extends their interpretation by giving charge density and mass density, and the four-velocity that describes their motion geometric definitions. These geometric definitions are reminiscent of General Relativity’s interpretation of mass in terms of the scalar curvature R and hint at the emergence of gravity. The gravitational theory that does emerge is shown to be equivalent to Einstein’s General Relativity augmented by an energy-momentum tensor term that mimics the properties of dark matter and/or dark energy. In summary, the proposed geometrization of the Maxwell tensor puts both electromagnetic and gravitational phenomena on an equal footing with both being tied to the curvature of space-time. Using specific solutions to the proposed theory, the unification brought to electromagnetic and gravitational phenomena, as well as the relationship of those solutions to the corresponding solutions of the classical Maxwell and Einstein field equations are compared.
Sustainable Entrepreneurship and Corporate Social Responsibility: Systematic Bibliometric Literature Review
Authors: Rosário Albérico Travassos , Figueiredo José
Published: May 2023

At a basic level, entrepreneurship refers to an individual or a small group of partners that intend to create a new business. Entrepreneurship is at forefront of any competitive economy due to the creation of new products and services that comes from new ideas. In other words, entrepreneurship is associated with economic wealth, growth and innovation. The usage of resources in the creation of new businesses needs to be rational because investors normally are risk averse, and nowadays, the purpose of a new business needs to be for a long-term period, and the usage of resources has to take into mind the possible damage to the planet. In other words, entrepreneurs and the sustainability of the planet are interconnected. Beyond this, entrepreneurs need to take care of the corporate social responsibility of each new business, considering the interests of itself, its stakeholders, and the public. Nevertheless, existing research has not shown in full all the research streams, how they interact with each other and their potential knowledge development. Thus, a literature review on social entrepreneurship and corporate social responsibility in the last decade are opportune. This paper aims to identify research trends in the field through a Systematic Bibliometric Literature Review of social entrepreneurship and corporate social responsibility research. The review includes 69 articles published in the Scopus® database, presenting up-to-date knowledge on the topic.
Review of Nature based Ecohydraulic Aquaforest Technology for Coastal Resilience and Sea Level Rise Climate-Induced Adaptation - Part A
Authors: Olanrewaju Oladokun Sulaiman , Lazzaro Umberto
Published: May 2023

One-fifth of the world’s population and critical infrastructures are near the coast and regions at high risk of sea level elevation. Climate change is expected to increase coastal extreme events, rising sea levels, and impact on ecosystem. This paper reviews coastal physical processes, wave and impacts, and the introduction of nature-based models for the mitigation of flooding, erosion, and recovery. Hard engineering like seawalls has been used to prevent, protect, and control water-based environmental forces with an extended impact on the land. A nature-based engineering solution, such as growing vegetation, is being adopted as a sustainable solution to help make existing technology live its design life and provide climate change adaptation and resilience for coastal and riverine communities. This paper presents applications of seaweed farms as an advanced nature-based mitigation approach. The result of the experiments conducted at RWTH Aachen University on wave damping of seaweed types and farming structures to validate the hypothesis will be presented in part B. A soft engineering approach to designing future vegetated protection systems using seaweed as a nature-based solution can help existing coastal infrastructure design life and protect against climate-induced SLR rise and adaptation, coastal risk mitigation, ecosystem restoration, and blue bio-economic development.
Thyroid Nodules and Obesity
Authors: Demetriou Elpida , Fokou Maria , Frangos Savvas , Papageorgis Panagiotis , Economides Panayiotis A , Ecocomides Aliki
Published: May 2023

A widely discussed topic in the pathophysiology of thyroid nodules is the role of obesity that leads to increased systemic inflammatory markers. Leptin plays a vital role in forming thyroid nodules and cancer through several mechanisms. Together with chronic inflammation, there is an augmentation in the secretion of tumor necrosis factor (TNF) and cytokines interleukin 6 (IL-6), contributing to cancer development, progression and metastasis. In addition, leptin exerts a modulatory action in the growth, proliferation and invasion of thyroid carcinoma cell lines via activating various signal pathways, such as Janus kinase/signal transducer and activator of transcription, mitogen-activated protein kinase (MAPK) and/or phosphoinositide 3-kinase (PI3K) /protein kinase B (Akt). Through several proposed mechanisms, aberrant endogenous estrogen levels have been suggested to play a vital role in the development of both benign and malignant nodules. Metabolic syndrome triggers the development of thyroid nodules by stimulating thyroid proliferation and angiogenesis due to hyperinsulinemia, hyperglycemia and dyslipidemia. Insulin resistance influences the distribution and structure of the thyroid blood vessels. Insulin growth factor -1 (IGF-1) and insulin affect the regulation of the expression of thyroid genes and the proliferation and differentiation of thyroid cells. TSH can promote the differentiation of pre-adipocytes to mature adipocytes, but also, in the presence of insulin, TSH possesses mitogenic properties. This review aims to summarize the underlying mechanisms explaining the role of obesity in the pathophysiology of thyroid nodules and discuss potential clinical implications.

Published: May 2023

A cross-sectional study was applied to investigate the influence of food systems and food environments on food choices and nutrition transition of households in Limpopo province, South Africa. A sample of 429 households were systematically selected using a paper selection draw from three districts. Food systems, food environments, food choices, and nutritional measurements of the households and informants were assessed, using a validated questionnaire. Most of the household informants responsible for food procurement were females (80.4%). There was a significant association (p < 0.001) between proximity to food stores and dietary diversity of the households. Staple foods were available in almost all surveyed households (95.6%). More than half of the households (59.8%) had home gardens in their yards. Almost half of the households (48.4%) had a low Dietary Diversity Score. The study revealed that 46.0% of households were food secure. Over a third (36.2%) of households’ informants were obese and 32.5% were diabetic. The mean total blood cholesterol was 3.69 ± 0.74 mmol/L. A high percentage of both females (89.6%) and males (91.5%) had normal haemoglobin levels. Most of the informants had normal systolic blood pressure levels (63%), with just over half who had high diastolic levels (57%). The 25 coping strategies were applied during food shortages periods. Even though the food environments provided both obesogenic and protective foods, the consumption of unhealthy foods was high.

Authors: Chereches Marius Calin , Finta Hajnal , Popa Cristian Olimpiu , Stefanescu Daniela , Muntean Daniela-Lucia
Published: May 2023

This study aimed to investigate Romanian physicians' awareness, recommendation practices, and opinions regarding using Foods for Special Medical Purposes (FSMPs) products. A total of ten physicians were interviewed using a structured questionnaire, and their responses were analysed using thematic content analysis. The study found that physicians were aware of FSMPs and recommended them to their patients based on nutritional deficits, weight loss, or deglutition impairments. In addition, disease stage, treatment scheme, taste, affordability, and availability were identified as factors influencing the recommendation and use of FSMPs. While physicians generally did not consult clinical trials, clinical experience was deemed essential for recommending FSMPs to patients. Patients' feedback regarding the usage and sourcing of FSMPs was generally positive, with some expressing concerns about the availability of different flavours and the costs of purchasing the products. The study concludes that physicians play a vital role in recommending FSMPs to patients and ensuring they have the necessary nutritional support during treatment. However, more patient education materials and collaboration with nutritionists may be required to improve patient outcomes and reduce patient financial burden.
Long Non-Coding RNAs as Emerging Targets in Lung Cancer
Authors: Gencel-Augusto Jovanka , Wu Wei , Bivona Trever G.
Published: May 2023

Long non-coding RNAs (LncRNAs) are mRNA-like molecules that do not encode for proteins and that are longer than 200 nucleotides. LncRNAs play important biological roles in normal cell physiology and organism development. Therefore, deregulation of their activities is involved in disease processes such as cancer. Lung cancer is the leading cause of cancer-related deaths due to late stage at diagnosis, distant metastasis, and high rates of therapeutic failure. LncRNAs are emerging as important molecules in lung cancer for their oncogenic or tumor suppressive functions. LncRNAs are highly stable in circulation, presenting an opportunity for use as non-invasive and early-stage cancer diagnostic tools. Here, we summarize latest works providing in vivo evidence available for LncRNAs role in cancer development, therapy-induced resistance, and their potential as biomarkers for diagnosis and prognosis, with a focus on lung cancer. Additionally, we discuss current therapeutic approaches to target LncRNAs. The evidence discussed here strongly suggests that investigation of LncRNAs in lung cancer in addition to protein-coding genes will provide a holistic view of molecular mechanisms of cancer initiation, development, and progression, and could open a new avenue for cancer treatment.

Authors: Pérez Tenezaca Nancy Estefanía , Rodríguez Castillo Juliana , Calderón Alemán Doris Eliana , Medina-Sotomayor Priscilla , Delgado María Augusta
Published: May 2023

Background: Dental avulsion is the most serious dentoalveolar traumas because its management requires immediate reimplantation to maintain the periodontal ligament. The success of the treatment depends largely on the appropriate storage medium that ensures the viability of the periodontal cells. The purpose of this review was to identify the most efficient media to store and transport avulsed permanent teeth, according to the viability of the periodontal ligament cells. Methods: The Scopus, Web of Science and PubMed electronically searched using the keywords “Storage media”; “Avulsed teeth”; and “Periodontal ligament”. The inclusion criteria were in vitro studies and articles published in English. The exclusion criteria were literature reviews, studies in primary teeth, studies in animals, and cell culture studies. Results: Hank’s saline solution and honey were equally effective, maintaining a cell viability rate of 98.89% and 96.43%, respectively, over a period of 3 hours. Ringer’s lactate solution maintained the viability of 906.40 viable cells/mm3 at 1 hour. Propolis maintained the viability of 285,000 cells/mm3 at 45 minutes, and the Neem extract maintained a cell viability rate of 88% at 30 minutes. Conclusions: Hank’s saline solution is the most effective storage medium for maintaining the viability of periodontal cells in avulsed teeth.
Segregation of Fast-Reactive Species in Atmospheric Turbulent Flow
Authors: Brasseur Guy P. , Barth Mary , Kazil Jan , Patton Edward , Wang Yuting
Published: May 2023

Atmospheric turbulence, which produces chaotic motions in the planetary boundary layer, can inhibit mixing between fast-reacting species produced or released at different locations. This segregation process modifies the effective rate at which reactions occur between these species, and are not appropriately accounted for in coarse resolution models since these models assume complete mixing of tracers within each gridbox. Here we present a few examples of LES-based simulations applied to chemically reactive species in a forested area with high emissions of biogenic hydrocarbons, an urban area rich in anthropogenic emissions; and a maritime area with high emissions of reduced sulfur species.
Frontal Incomes and Quality of Life in Obese Patients With and Without Binge Eating Disorder
Authors: Gameiro Fátima , Rosa Beatriz , Faria Miguel
Published: May 2023

Frontal incomes play an important role in human behavioral regulation and can be a determinant of eating behavior. The aim of this study was to analyse the frontal incomes in obese patients with and without Binge Eating Disorder (BED), compared to normoweight (NW) subjects and to analyse the effect of sex and binge disorder on quality of life, with age and BMI as covariates. A total of 114 participants comprised three different groups (obese with BED, obese without BED and NW) completed the Frontal Assessment Battery (FAB) and Impact of Weight on Quality of Life (IWQOL-lite). The results showed that obese patients, with and without BED, have poorer frontal functioning than NW persons. Obese patients with BED have lower performance in frontal income than obese patients without BED. Male participants have a higher perception of quality of life in all dimensions, with women showing lower values in self-esteem and sex life. Obese with BED show greater weaknesses in physical function. These results suggest that low frontal incomes and worse quality of life characterize obese patients, more evident in obese patients with BED.
Quick and Complete Convergence in the Law of Large Numbers with Applications to Statistics
Authors: Tartakovsky Alexander
Published: May 2023

In the first part of this article, we discuss and generalize the complete convergence introduced by Hsu and Robbins (1947) to the r-complete convergence introduced by Tartakovsky (1998). We also establish its relation to the r-quick convergence first introduced by Strassen (1967) and extensively studied by Lai (1976). Our work is motivated by various statistical problems, mostly in sequential analysis. As we show in the second part, generalizing and studying these convergence modes is important not only in probability theory but also to solve challenging statistical problems in hypothesis testing and changepoint detection for general stochastic non-i.i.d. models.

Published: May 2023

The novel coronavirus disease 2019 (COVID-19) known as severe acute respiratory syndrome - coronavirus 2 (SARS-CoV-2) has emerged in China in 2019, and caused an outbreak of unusual viral pneumonia. The olfactory dysfunction following the infection of different variants of SARS-CoV-2 is now accepted as a hallmark symptom in patients. Recent studies have pointed out the relationship between COVID-19 and altered or loss of smell in infected patients. This mini review provides an overview of the role of SARS-CoV-2 and the other acute respiratory viruses in the development the human olfactory pathophysiology. We highlight the importance of deciphering the molecular mechanisms underlying the olfactory dysfunction caused by SARS-CoV-2 to help design new drugs to restore the altered or loss of smell in affected patients.
Peripapillary Intrachoroidal Cavitation
Authors: Ehongo Adèle , Bacq Noélie
Published: May 2023

Peripapillary intrachoroidal cavitation (PICC) is a yellow-orange lesion, located at the outer border of the myopic conus. First described as a localized detachment of the retinal pigment epithelium, its intrachoroidal location was later disclosed, justifying its current name. PICC is related to other myopic complications like posterior staphyloma, but its pathogenesis is not clear to date. Although it has been considered a benign condition, most eyes with PICC show visual field defects, leading to diagnostic uncertainty as these deficits resemble those observed in glaucoma. Furthermore, eyes with PICC can develop macular detachment with retinoschisis. Finally, misdiagnosis of PICC as a metastatic choroidal tumor may lead to unnecessary and anxiety-provoking investigation. Advances in optical coherence tomography (OCT) imaging have improved the visualization of ocular structures, contributing to the understanding of PICC. Recently high optic nerve sheaths traction forces during eye movements in highly myopic eyes have been suggested as promoters of PICC, renewing interest around this condition. However, a review of PICC is still lacking. Therefore, we aimed to provide a concise yet comprehensive overview of the current state of the art, focusing on OCT documentation, pathophysiology and potential future perspectives based on biomechanics of the optic nerve.

Published: May 2023

With permafrost degenerating caused by climate change, water accumulation increases in permafrost regions during last decades. Water accumulation will deteriorate existing status of engineering in cold regions. Water accumulation can make a thermal effect on permafrost under construction, even result in failure of the subgrade. Moreover, the thermal effect is related to water temperature. However, temperature variation of water accumulation is complex, and its influence factors include air temperature, environment, scope of water accumulation and so on. In order to make analysis of the damage mechanism of water accumulation on permafrost, it is necessary to explore the internal temperature change of water accumulation. This paper proposes a review about temperature calculation method of water accumulation in cold environment. The thermal calculation method between air and water boundary of water accumulation is summarized. Water temperature change of water accumulation with various type is analyzed. The thermal calculation considering phase transformation in water accumulation is discussed, and heat transfer from the bottom of water accumulation to the underlying soil is further studied. Finally, the key factors which are advantageous to make research about the thermal effect of water accumulation in permafrost is proposed to optimize calculation method.

Authors: Zhang Yuhan , Ma Kaifeng , Li Qingwei
Published: May 2023

Heat requirements play an important role in plant flowering, and control the flowering period of woody ornamental plants to a certain extent. In this study, the perennial potted seedlings of four typical Prunus mume cultivars 'Xiaolve', 'Baixuzhusha', 'Fenghou' and 'Danfenghou' were used as materials. The way of regulating the cultivation temperature is adopted to achieve the purpose of relieving the natural dormancy and forcing the blooming of P. mume. Its content includes the research on the heat requirements of P. mume cultivars widely planted in Beijing, and the analysis of the influence of different facility cultivation temperatures on the flowering characteristics of P. mume, providing a theoretical basis for further exploring the cultivation techniques of P. mume bonsai flowering regulation. The results showed that, according to the Growing degree-hour model, the HR of 'Xiaolve', 'Baixuzhusha', 'Fenghou' and 'Danfenghou' flower buds were 3583.70 GDH℃, 3217.30 GDH ℃, 3996.50 GDH ℃, 4732.20 GDH ℃, respectively. According to the effective accumulated temperature model, the HRs of above cultivars were 350.65 ℃, 319.30 ℃, 510.30 ℃, 558.50 ℃, respectively. In addition, the temperature of different cultivation facilities did not significantly change the flowering quality such as flower diameter and fragrance. Temperature also affects the growth and development speed, affecting the flowering time. Under the facility environment with higher temperatures, the flowering process is faster and the flowering period is shorter.

Authors: Wu Erxi , Wang Qiaozhi , Ke Lihua , Zhang Guangquan
Published: May 2023

A scientific carbon accounting system can help enterprises reduce carbon emissions. This study took the enterprise in the Yangtze River basin as a case study. The accounting classification of carbon emissions in the life cycle of lime production was assessed, and the composition of the sources of carbon emission was analyzed, covering mining explosives, fuel (diesel, coal), electricity and high temperature limestone decomposition. Using the IPCC emission factor method, a carbon life cycle emission accounting model for lime production was established. We determined that a total of 354,200 tons of carbon emissions were generated from producing 321,000 tons of lime in a year. The decomposition of limestone at a high temperature was the largest carbon emission source, accounting for 62.34% of the total carbon emission. Coal combustion was also an important source of carbon emissions, accounting for 32.66% of total carbon emissions. The carbon emission for one ton of activated lime was 1.46kg, 1.49kg, 1100kg and 1102.95kg respectively for the open-pit, mining stage, crushing stage, and the calcination stage. Based upon the main sources of carbon emission for lime production, carbon emission reduction should focus on CO2 capture technology, fuel optimization and energy control. Using our analysis of carbon emissions, the carbon emission factor of producing unit quicklime of the lime enterprise in the Yangtze River basin was determined. Furthermore, the research into carbon emission reduction for lime production can provide a point of reference for the promotion of carbon neutrality in the same industry.

We aimed to evaluate the magnesium content in human cirrhotic liver and its correlation with serum AST levels, expression of hepatocellular injury, and MELDNa prognostic score. In liver biopsies obtained at liver transplantation we measured the magnesium content in liver tissue in 27 cirrhotic patients (CIRs) and 16 deceased donors with healthy liver (CTRLs) by atomic absorption spectrometry and within hepatocytes in 15 CIRs using synchrotron-based X-ray Fluorescence Microscopy. In 31 CIRs and 10 CTRLs we evaluated the immunohistochemical expression in hepatocytes of the transient receptor potential melastatin 7 (TRPM7), a magnesium influx chanzyme also involved in inflammation. CIRs showed a lower hepatic magnesium content [117.2 (IQR 110.5-132.9) vs 162.8 (IQR 155.9-169.8) μg/g; p<0.001] and a higher percentage of TRPM7 positive hepatocytes [53.0 (IQR 36.8-62.0) vs 20.7 (10.7-32.8) %; p<0.001) than CTRLs. In CIRs, MELDNa and serum AST at transplant correlated: a) inversely with the magnesium content both in liver tissue and hepatocytes; b) directly with the percentage of hepatocytes stained intensely for TRPM7. The latter also directly correlated with worsening of MELDNa at transplant compared to waitlisting. Magnesium depletion and overexpression of its influx chanzyme TRPM7 in hepatocytes are associated with severity of hepatocyte injury and prognosis in cirrhosis. These data represent the pathophysiological basis for a possible beneficial effect of magnesium supplementation in cirrhotic patients.

Intrinsic Coherence Length Anisotropy in Nickelates, and Some Pnictides and Chalcogenides Superconductors
Authors: Talantsev Evgeny F.
Published: May 2023

Nickelate superconductors, R1-xAxNiO2 (where R is a rare earth metal and A = Sr, Ca), experimentally discovered in 2019 exhibit many unexplained mysteries as the existence of a superconducting state with Tc (up to 18 K) in thin films and its absence in bulk materials. Another unexplained mystery of nickelates is their temperature-dependent upper critical field, Bc2T, which can be nicely fitted to two-dimensional (2D) models; however the deduced film thickness, dsc,GL, exceeds the physical film thickness, dsc, by a manifold. To address the latter, it should be noted that 2D models assume that dsc is less than the in-plane and out-of-plane ground state coherence lengths, dsc<ξab0 and dsc<ξc0, respectively, and, in addition, that the inequality ξc0<ξab0 satisfies. Analysis of the reported experimental Bc2T data showed that at least one of these conditions does not satisfy for R1-xAxNiO2 films. This implies that nickelate films are not 2D superconductors, even despite though that the superconducting state is observed only in thin films. Based on this, here we proposed analytical three dimensional (3D) model for global data fit of in-plane and out-of-plane Bc2T in nickelates. The model is based on a heuristic expression for temperature dependent coherence length anisotropy: γξT=γξ01-1a×TTc, where a>1 is a unitless free-fitting parameter. The proposed expression for γξT, perhaps, has a much broader application because it has been successfully applied to bulk pnictide and chalcogenide superconductors.
Presence of Phthalate Esters Used as Common Plasticisers in Maltese Shoreline Sand
Authors: Muscat Marija , Sinagra Emmanuel , Lia Frederick
Published: May 2023

DBP and DEHP are two of the most common plasticisers used in modern industries, which have aroused a major concern over their ubiquitous occurrence and hazardous environmental effects. This study presents the first data of phthalates’ occurrence and distribution in the Maltese shoreline sand. DBP and DEHP occurrences’ was investigated in three busy and secluded beaches, respectively. Analytical determination involved quantifying DBP and DEHP from 75 samples using UPLC-MS/MS through triple repeatability. The concentrations ranged between 0.0095–0.07034 µg/g and <LOQ–0.0977 µg/g for DBP and DEHP, respectively. Statistical analysis of the comparison of phthalates in different beaches demonstrated that the occurrence of DBP and DEHP in Maltese shoreline sand varies. The differences in the occurrence of phthalates were attributed to the beaches’ topography and anthropogenic pressures. Analysis of the effects of anthropogenic activities on the occurrence of phthalates showed a positive association. Distribution analysis showed that DBP and DEHP exhibit an uneven distribution along the shoreline. Conversely, different distributions were observed at distances away from the sea. The uneven distributions observed were associated with anthropogenic activities, different chemodynamic properties and wave action. Cluster analysis was performed to prove the interactions between the phthalates’ concentrations and the characteristics of the beaches.
The Influence of Time in a Theory of Nature
Authors: Oldani Richard
Published: May 2023

We think of time as one of four dimensions appearing in the equations of motion of Newtonian and quantum physics, but participating independently of space. In these pages we explore the way the time variable affects how space is perceived. We show first that non-commutation may be interpreted as the difference between electron and photon cycling during radiation processes. For every electron cycle of a quantum oscillator there are two photon cycles. Secondly, the difference between relativistic and non-relativistic quantum mechanics is shown to be related to time evolution. Only relativistic models evolve continuously. The reasoning of Einstein is implicit to an understanding of both physical models. Previously obtained derivations of relativistic quantum mechanics are reaffirmed by following the ideas of Dirac.

Dental healthcare providers, staff and patients are constantly exposed to the risk of infection or cross-infection in the dental office, particularly due to the formation of biofilms within Dental Unit Waterlines (DUWLs). Good water quality, achieved with environmentally friendly means, is essential in ensuring the safe operation of the clinic. The aim of this study was to evaluate the practices and protocols used in dental offices of Metropolitan Athens in Greece with regards to water quality in DUWLs. The questionnaire about water quality was distributed to dental practitioners in 2022 and was completed by 206 dentists. Water supplied to dental units was mainly from the public network (65.0%), with 55.8% using in-office filtration. Most dentists (71.8%) do not know the active substance of the antiseptic used for the DUWLs, while 96.1% reported having an antiseptic reservoir embedded in the dental unit. Daily flushing with a small and a large amount of fluid was practiced in approximately 83% and 61% of dental offices, respectively. Dental associations should raise awareness regarding water quality and maintenance of DUWLs in dental offices, investing in lifelong learning, while implementing protocols and green strategies.
Decaying Turbulence as a Fractal Curve
Authors: Migdal Alexander
Published: May 2023

We develop a quantitative microscopic theory of decaying Turbulence by studying the dimensional reduction of the Navier-Stokes loop equation for the velocity circulation. We have found an infinite dimensional manifold of solutions of the Navier-Stokes loop equation\cite{M93, M23PR} for the Wilson loop in decaying Turbulence in arbitrary dimension $d >2$. This family of solutions corresponds to a fractal curve in complex space $\mathbb C^d$, described by an algebraic equation between consecutive positions. The probability measure is explicitly constructed in terms of products of conventional measures for orthogonal group $SO(d)$ and a sphere $\mathbb S^{d-3}$. In three dimensions $d=3$, we compute a fractal dimension $d_f = 1.07$ for this fractal curve and the step size CDF with fat tail $x^{-2.15} $. We also compute the enstrophy CDF with fat tail $x^{-0.951}$, corresponding to an infinite mean value (anomalous dissipation). The energy density of the fluid decays as $\mathcal E_0/t$, where $\mathcal E_0$ is an initial dissipation rate. Presumably, we have found a new phase of extreme Turbulence not yet observed in real or numerical experiments.

Importance of Considering Enzyme Degradation for Interpreting the Response of Soil Enzyme Activity to Nutrient Addition: Insights from a Field and Laboratory Study

Soil enzyme activity can be affected by both production and degradation, as enzymes can be degraded by proteases. However, the impact of nutrient addition on enzyme activity is often solely attributed to changes in enzyme production without fully considering degradation. Here, we demonstrated that the activities of β-1,4-glucosidase (BG), β-D-cellobiohydrolase (CBH), β-1,4-Xylosidase (BX), and β-1,4-N-acetyl-glucosaminnidase (NAG) were comparable in nitrogen (N) and phosphorus (P) fertilized soils and the unfertilized control under field conditions, but the reduction in activity was substantially greater in the fertilized soils during short-term laboratory incubation. The results show that the interruption of the natural, continuous supply of organic matter or non-soil microbial-derived enzymes, which typically occurs under field conditions, leads to a more significant reduction in apparent enzyme activities in fertilized soils compared to unfertilized control. This may be attributed to the higher abundance of protease in fertilized soils, resulting in faster enzyme degradation. Interestingly, P fertilization alone did not have a similar effect, indicating that N fertilization is likely the main cause of the larger decreases in enzyme activity during incubation in fertilized soils compared to unfertilized control soils, despite our study site being poor in P and rich in N. These findings highlight the importance of considering enzyme degradation when investigating material dynamics in forest ecosystems, including the impact of nutrient addition on enzyme activity, as enzyme production alone may not fully explain changes in apparent enzyme activity.
Methods to Reproduce in-Plane Deformability of Orthotropic Floors in Finite Element Models of Buildings

Published: May 2023

This paper investigates the classical but yet intriguing question of modeling orthotropic RC floor systems endowed with lightening elements, by means of a uniform orthotropic slab, in order to describe accurately the building response under seismic loads. The simplified method, commonly adopted by engineers, based on the equivalence between the transverse stiffness of the RC elements of the real floor and those of the orthotropic slab is presented. A case study in which this simplified method is used is also provided. Then, an advanced finite elements (FE) based method to determine the elastic properties of the equivalent homogenized orthotropic slab is proposed. Based on the results obtained from the application of this method to a case study, a discussion on the adequacy of the simplified method is also provided.
Microscopical Analysis of Autofluorescence as a Complementary and Useful Method to Assess Differences in Anatomy and Structural Distribution Underlying Evolutive Variation in Loss of Seed Dispersal in Common Bean

Common bean has received attention as a model plant for legume studies, but little information is available about the morphology of its pods and the relation of this morphology to loss of seed dispersal and/or the pod string, which are key agronomic traits of legume domestication. Dehiscence is related to pod morphology and the anatomy of pod tissues because of the weakening of the dorsal and ventral dehiscence zones and the tensions of the pod walls. These tensions are produced by the differential mechanical properties of lignified and non-lignified tissues and changes in turgor associated with fruit maturation. In this research, we histologically studied the dehiscence zone of the ventral and dorsal sutures of the pod in two contrasting genotypes for dehiscence and string, by comparing different histochemical methods with autofluorescence. We found that the secondary cell wall modifications of the ventral suture of the pod were clearly different between the dehiscence-susceptible and stringy PHA1037 and the dehiscence-resistant and stringless PHA0595 genotypes. The susceptible genotype had cells of bundle caps arranged in a more easily breakable bowtie knot shape. The resistant genotype had a larger vascular bundle area and fibre cap cells (FCCs), and due to their thickness, the external valve margin cells were significantly stronger than those from PHA1037. Our findings suggest that the FCC area, and the cell arrangement in the bundle cap, might be a partial structure involved in the pod dehiscence of common bean. The autofluorescence pattern at the ventral suture allowed us to quickly identify the dehiscent phenotype and gain a better understanding of cell wall tissue modifications that took place along the bean's evolution, which had an impact on crop improvement. We report a simple autofluorescence protocol to reliably identify secondary cell wall organization and its relationship to dehiscence and string in common bean.
