Entre a Mitologia Indígena e o Fora de Campo: Notas sobre a espectralidade em Hamaca Paraguaya (2006)
Authors: Ricardo Lessa Filho
Published: January 2023

O presente ensaio analisa o filme Hamaca paraguaya (2006), de Paz Encina, o primeiro longa-metragem realizado no Paraguai desde 1978, para discutir a maneira como a cineasta paraguaia concebe a transmutação do mito indígena dos guaranis para a linguagem cinematográfica e ficcional. O texto examina escolhas formais do filme de Encina, tais como a dessincronização entre a imagem e o som e, sobretudo, seu importante e singular exercício estético e temporal com o fora de campo a partir de sua espectralidade e de suas encenações entre o visível e o invisível.
A Voz Neotênica: Possibilidades de voz não-fonocêntrica no cinema
Authors: Bubniak Fabiana
Published: January 2023

Este artigo se situa no campo dos estudos da linguagem e propõe a existência de uma voz neotênica no cinema. Após uma revisão da literatura que trata de noções de voz, fala e silêncio, são discutidos conceitos de Jacques Derrida, Aristóteles, Steven Connor, Mladen Dolar e Jonathan Rée, bem como a definição de voz na psicanálise com base nas teorias de Jacques Lacan. A partir do conceito de infância da linguagem de Giorgio Agamben e de neotenia, torna-se possível conceituar a voz neotênica. Esta emerge quando se transcende o sentido (logos) e a materialidade (phoné), situando-se num hiato entre a língua e o discurso. A possibilidades dessa voz no cinema é explorada através da análise dos filmes Amor (2012) de Michael Haneke, Ela (2013) de Spike Jonze, Um Lugar Silencioso (2018) de John Krasinski, Bastardos Inglórios (2009) de Quentin Tarantino e Noivo Neurótico, Noiva Nervosa (1977) de Woody Allen.

Where to look? Sustaining Presence While Directing Attention in Virtual Reality Stories.
Authors: Walter Michael
Published: January 2023

Humans have been fascinated with the notion of submerging themselves in other spaces since antiquity, or even before. As the contemporary media landscape seeks to employ newer immersive practices, particularly in today’s Metaverse environment, storytelling in immersive media such as virtual reality (VR) is still developing and being described. The notion of scale and (newfound) viewer agency afforded by VR has challenged VR film-makers, particularly in directing attention towards story beats and handling user interaction. The video gaming industry, as a platform that is built with immersion as the core of the experience, leads this development. The advent of virtual reality (VR) video games is developing an amalgamation of immersive strategies to induce the sense of presence within virtual worlds. In this article I look at current approaches and challenges faced when directing attention in films and storytelling in VR. I then consider strides taken in VR video games, namely Half-Life: Alyx (2020), to propose that directing techniques and immersive strategies employed in VR video games can be used to develop new strategies in VR films and storytelling.
Realidade Virtual Cinematográfica: Contar ou viver histórias em ambientes virtuais
Authors: Merino Francisco
Published: January 2023

A emergência da Realidade Virtual (RV) e o seu progressivo refinamento como modalidade de expressão imersiva permitiram o desenvolvimento de formatos híbridos, como a Realidade Virtual Cinematográfica – o objecto deste estudo – que combina os modos de representação narrativos da RV e do cinema. Partindo do pressuposto que os esquemas percetivos e os processos de narração estão intimamente vinculados ao meio, iremos proceder a uma análise comparativa que pretende identificar as simetrias e diferenças no modo como RV e o cinema contam histórias. A nossa atenção focar-se-á, sobretudo, nas divergências funcionais e ontológicas entre o processo de contar uma história e a experiência de a viver num ambiente virtual, recorrendo a categorias e conceitos extraídos da narratologia, dos estudos fílmicos e dos novos meios com o propósito de contribuir para uma teoria geral da narração em RV e de melhor compreender o vínculo desta à linguagem cinematográfica.

Immersion and Expanded Spectatorships: Notes on a Reinvented Field
Authors: Flores Victor , S. Martins Susana
Published: January 2023

The special section “Immersion and expanded spectatorships” discusses how moving images have been intensely reinvented in recent virtual environments, promoting renewed forms of viewing that change and broaden the spectator’s experience. Engaging with the fact that the history of immersive media is often difficult to reconstruct and categorize clearly, the four essays here gathered reflect precisely such plurality of research lines. Simultaneously, they further demonstrate how this field has for long been shaped — and continues to be so — in a hybrid manner, through fruitful dialogues and mutual contamination.
My understanding of the origin, prevention and treatment of new pneumonia virus disease
Authors: Chunwu Sun
Published: January 2023

the incidence rate of the world epidemic is many, long and wide. There are at least five reasons. In 1931, the American doctor drbaxbr cooperated with his colleagues to produce the world's first bottle of commercial infusion products in the transformed old garage. In the Second World War, it was widely used in the rescue and treatment of dehydration, excessive bleeding, fever and wound infection. For example, within 30 hours of infusion, the patient's fever will be reduced immediately, the infected wound will be treated with western medicine, especially for bacteria. At that time, the side effects of chronic diseases, viruses and long-term infusion could not be found in a short time.

Firstly, it discusses the origin and prevention of the new pneumonia virus disease, so as to establish effective national epidemic prevention and recapture the economic losses in the epidemic situation.

Authors: Amabilis-Sosa Leonel Ernesto , Rodríguez-Mata Abraham Efraím , Baray-Arana Rogelio , Robles-Vega Isidro , Gonzalez-Huitrón Victor Alejandro , López-Pérez Pablo Antonio
Published: January 2023

In this article, the theory of fractional control and state estimation applied to biological science is studied, particularly in hybrid wastewater treatment. For nonlinear systems with stable and known states, an interconnected fractional robust control design with high gain state estimation is proposed to generate a control insensitive to nutritional perturbations originated by an advanced oxidation process in a microalgae culture. An online study is proposed for the mineralization of glyphosate and its feedback in a microalgae cultivation process where through the designed control the light dynamics is manipulated to robustly and automatically regulate the biomass signal provided by an analog sensor and nutrient estimation via state observers. In the literature, there are few results developed with real-time results. This work is a multidisciplinary study with online results where the performance and improvement of the proposed complex process are concluded.
Remarks on algebraic dynamics in positive characteristic
Authors: Xie Junyi
Published: January 2023

In this paper, we study arithmetic dynamics in arbitrary characteristic, in particular in positive characteristic. Applying the arithmetic degree and canonical height in positive characteristic, we prove the Dynamical Mordell–Lang Conjecture for automorphisms of projective surfaces of positive entropy, the Zariski Dense Orbit Conjecture for automorphisms of projective surfaces and for endomorphisms of projective varieties with large first dynamical degree. We also study ergodic theory for constructible topology. For example, we prove the equidistribution of backward orbits for finite flat endomorphisms with large topological degree. As applications, we give a simple proof for weak dynamical Mordell–Lang and prove a counting result for backward orbits without multiplicities. This gives some applications for equidistributions on Berkovich spaces.
Sharp Li–Yau inequalities for Dunkl harmonic oscillators
Authors: Li Huaiqian , Qian Bin
Published: January 2023

We study the Li–Yau inequality for the heat equation corresponding to the Dunkl harmonic oscillator, which is a nonlocal Schrödinger operator parameterized by reflections and multiplicity functions. In the particular case when the reflection group is isomorphic to

ℤ

d

{\mathbb{Z}_{2}^{d}}

, the result is sharp in the sense that equality is achieved by the heat kernel of the classic harmonic oscillator. We also provide the application on parabolic Harnack inequalities.
Finite-time attractivity of strong solutions for generalized nonlinear abstract Rayleigh–Stokes equations
Authors: Tuan Tran Van
Published: January 2023

In the present paper, we address the global solvability and finite-time attractivity of strong solutions for an abstract Rayleigh–Stokes-type equation involving nonlinear perturbations in Hilbert spaces. Based on regularity estimates of resolvent operator, local estimates on Hilbert scales and fixed
point arguments, we obtain some results on global existence and finite-time attractivity of strong solutions to our problem.
The factorization method for a penetrable cavity scattering with interior near-field measurements
Authors: Wu Qinghua , Guo Jun , Yan Guozheng
Published: January 2023

This paper is concerned with the inverse scattering problem of time-harmonic acoustic waves from a penetrable cavity bounded by a layered structure and seeks to determine the shape and location of the cavity from interior near-field measurements.
Of particular interest is that the near-field operator does not satisfy the main theorem of the factorization method, so we introduce a modified near-field operator and prove that it can be used to reconstruct the cavity.
Numerical examples demonstrate the feasibility and effectiveness of our algorithm.
1 × 2 power splitter based on photonics crystals fibers
Authors: Harrat Assia Ahlem , Debbal Mohammed , Ouadah Mohammed Chamse-Eddine
Published: January 2023

In this regard, we directed a theoretical study with numerical simulations. This study allowed us to illustrate how a photonic crystal fiber (PCF) structure could divide an optical signal. One of the most fundamental components used to construct photonic integrated circuits (PIC) is the splitter, which is using light coupling between the cores as a control until the output ports by using pure silica to replace some air-hole zones along the PCF axis and split the single signal on two ports with almost equal intensity in each port. Optical interconnects are one of the most basic components of integrated optics, and splitters for photonic power are a key element of a connected family. With the least amount of loss, a competent photonic splitter can guide light input of a certain wavelength to several ports at various intensities.
Hidden in plain sight in the delivery room – the Apgar score is biased
Authors: Grünebaum Amos , Bornstein Eran , Dudenhausen Joachim W. , Lenchner Erez , De Four Jones Monique , Varrey Aneesha , Lewis Dawnette , Chervenak Frank A.
Published: January 2023

Objectives

The objective of this study was to compare the maximum 5-min Apgar score of 10 among different U.S. races and Hispanic ethnicity.

Methods

Retrospective population-based cohort study from the National Center for Health Statistics (NCHS), and Division of Vital Statistics natality online database. We included only deliveries where the race and Hispanic ethnicity of the father and mother were listed as either Black, White, Chinese, or Asian Indian and as Hispanic or Latino origin or other. Proportions of 5-Minute Apgar scores of 10 were compared among different races and Hispanic ethnicity for six groups each for mother and father: Non-Hispanic or Latino White, Hispanic or Latino White, Non-Hispanic or Latino Black, Hispanic or Latino Black, Chinese, and Asian Indian.

Results

The study population consists of 9,710,066 mothers and 8,138,475 fathers from the US natality birth data 2016–2019. Black newborns had a less than 50% chance of having a 5-min Apgar score of 10 when compared to white newborns (OR 0.47 for Black mother and Black father; p<0.001). White babies (non-Hispanic and Hispanic) had the highest proportion of Apgar scores of 10 across all races and ethnicities.

Conclusions

The Apgar score introduces a bias by systematically lowering the score in people of color. Embedding skin color scoring into basic data and decisions of health care propagates race-based medicine. By removing the skin color portion of the Apgar score and with it’s racial and ethnic bias, we will provide more accuracy and equity when evaluating newborn babies worldwide.

Published: January 2023

Metabolic flux is the final output of cellular regulation and has been extensively studied for carbon but much less is known about nitrogen, which is another important building block for living organisms. For the tuberculosis pathogen, this is particularly important in informing the development of effective drugs targeting the pathogen's metabolism. Here we performed 13C15N dual isotopic labeling of Mycobacterium bovis BCG steady state cultures, quantified intracellular carbon and nitrogen fluxes and inferred reaction bidirectionalities. This was achieved by model scope extension and refinement, implemented in a multi‐atom transition model, within the statistical framework of Bayesian model averaging (BMA). Using BMA‐based 13C15N‐metabolic flux analysis, we jointly resolve carbon and nitrogen fluxes quantitatively. We provide the first nitrogen flux distributions for amino acid and nucleotide biosynthesis in mycobacteria and establish glutamate as the central node for nitrogen metabolism. We improved resolution of the notoriously elusive anaplerotic node in central carbon metabolism and revealed possible operation modes. Our study provides a powerful and statistically rigorous platform to simultaneously infer carbon and nitrogen metabolism in any biological system.

Published: January 2023

Eğitim, teknolojinin yeniliklerinden etkilenen önemli alanlardan biridir. Bu doğrultuda araştırmada fen eğitiminde, öğrenme ve öğretme sürecinde teknolojinin entegre edilmesi ile ilgili öğretmenlerin görüşlerini almak, bu konu ile ilgili yaşanan zorlukları, kolaylıkları ve teknoloji entegrasyonun öğrenci ve öğretmenlere sağladığı katkıları öğretmen gözünden belirlemek amaçlanmıştır. Araştırma İstanbul İlindeki devlet okullarında çalışan fen bilimleri öğretmenleri ile gerçekleştirilmiştir. Araştırmada nitel araştırma yöntemlerinden durum çalışması yöntemi kullanılmıştır. Mevcut durumu tespit etmek için fen bilimleri öğretmenlerine yapılandırılmış sorulardan oluşan anket uygulanmış, sonrasında verilere göre derslerde teknoloji entegrasyonunu deneyimleyen dört fen bilimleri öğretmeni ile yarı yapılandırılmış sorulardan oluşan odak grup görüşme yapılmıştır. Anket verilerinin analizi için içerik analizi yapılarak frekans ve yüzde kullanılırken odak grup görüşme için araştırmacılar tarafından daha önceden belirlenen kodlar kullanılarak betimsel analiz yapılmıştır. Belirlenen kodların uyumu için Miles ve Huberman’ın (1994) önerdiği güvenirlik formülü kullanılmış ve güvenirlik %90 olarak hesaplanmıştır. Araştırma verileri bazı öğretmenlerin teknolojik yeterlilikleri olduğunu belirtmelerine rağmen öğrenme ve öğretme ortamında teknolojik araç kullanma, web 2.0 araçlarını derslere entegre etme, öğrencilerin eğitici dijital ortamlarda deneyim kazanmalarını sağlama gibi konularda beklentiyi karşılamadıklarını ortaya koymuştur. Derslerde teknoloji entegrasyonu sağlama konusunda teknik aksaklıklar, öğrencilerin farklı içerik beklentileri, öğretmenlerin uzun bir hazırlık süreci geçirmeleri, teknik sıkıntılar gibi zorlayıcı durumlara karşın öğrencilerin aktif katılımlarını arttırması, öğrenci-öğrenci, öğrenci-öğretmen etkileşimini ve öğrenci merakını arttırması gibi olumlu yönleri ağır basmaktadır. Bu sonuçlardan, çeşitli çevresel uyaranlara karşı öğrencilerin daha hızlı tepki vermeleri, özgüvenlerinin artması, oluşan kavram yanılgılarını azaltmaları gibi olumlu katkıları öğrencilerin fikirleri, beklentileri ve ifade biçimleriyle daha net anlaşılmaktadır. Çalışma sonuçlarında belirtilen olumsuz durumlar çözüme kavuşturularak fen eğitiminde hem öğretmen hem de öğrenciler için bu araçların kullanılabilirliği ve derslere entegrasyonu arttırmalıdır.
Is there a relationship between surgical volume and outcome for total elbow arthroplasty? A systematic review
Authors: Prkić A , Vermeulen N P , Kooistra B W , The B , van den Bekerom M P J , Eygendaal D
Published: January 2023

Purpose: Total elbow arthroplasty (TEA) is rarely performed compared to other arthroplasties. For many surgical procedures, literature shows better outcomes when they are performed by experienced surgeons and in so-called ‘high-volume’ hospitals. We systematically reviewed the literature on the relationship between surgical volume and outcomes following TEA.

Methods: A literature search was performed using the MEDLINE, EMBASE and CINAHL databases. The literature was systematically reviewed for original studies comparing TEA outcomes among hospitals or surgeons with different annual or career volumes. For each study, data were collected on study design, indications for TEA, number of included patients, implant types, cut-off values for volume, number and types of complications, revision rate and functional outcome measures. The methodological quality of the included studies was assessed using the Newcastle–Ottawa Scale.

Results: Two studies, which included a combined 2301 TEAs, found that higher surgeon volumes were associated with lower revision rates. The examined complication rates did not differ between high- and low-volume surgeons. In one study, low-hospital volume is associated with an increased risk of revision compared to high-volume hospitals, but for other complication types, no difference was found.

Conclusions: Based on the results, the evidence suggests that high-volume centers have a lower revision rate in the long term. No minimum amount of procedures per year can be advised, as the included studies have different cut-off values between groups. As higher surgeon- and center-volume, (therefore presumably experience) appear to yield better outcomes, centralization of total elbow arthroplasty should be encouraged.
The system of norms on intentional homicide in the Criminal Code of Ukraine as a legal and technical prerequisite for the problems of their qualification according to the totality of crimes
Authors: Lomaha Yu.T.
Published: January 2023

The article is devoted to the study of the problems of the legal and technical description of the signs of premeditated murder in the system of norms about this offense in the Criminal Code of Ukraine in terms of their influence on potential problems of qualification for a set of criminal offenses. The Criminal Code of Ukraine contains a fairly extensive system of legal provisions that regulate responsibility for various types of murder. At the same time, the legislator uses various methods of describing the features of the composition of murders, some of which become nothing more than a legal and technical prerequisite for the emergence of problems in the future criminal-legal assessment of the committed murder in combination with other criminal offenses. A review of the system of norms on intentional homicide in the Criminal Code of Ukraine will help to determine the justification of the legislator’s use of those techniques of legal technique that can create potential problems of law enforcement. The purpose of the article was to highlight the system of norms on intentional homicide in the Criminal Code of Ukraine and the peculiarities of its normative regulation as a legal and technical prerequisite for the problems of qualification of intentional homicides by the totality of crimes. An attempt will be made in the article to prove the possibility of simplifying the description of the features of the composition of murders as a means of eliminating the problems of their adequate criminal-legal assessment. The information presented in the work gives grounds for the conclusion that the legislator’s use of unsuccessful legal and technical techniques in the construction of the articles of the Special Part of the Criminal Code of Ukraine, which contain a system of norms on responsibility for intentional homicide, creates potential problems in the application of these norms, calling into question the need to qualify the crimes committed offenses under a set of crimes. In this regard, it seems appropriate to introduce such changes to the Criminal Code of Ukraine that would remove doubts about the need to apply the general rule on murder, provided for in the relevant part of Art. 115 of the Criminal Code of Ukraine in combination with the norm on another criminal offense committed by a person. Such a legislative decision will make it possible to adequately qualify everything committed even if the attitude to the consequences in the form of death on the part of the guilty person was careless. In this case, the person may additionally be incriminated by the norm provided for in the relevant part of Art. 119 of the Criminal Code of Ukraine.
La COP
Authors: Acuña Chinchilla Evanny , Solano-Ruiz Jorge
Published: January 2023

El cambio climático ha sido un tema pertinente en las últimas décadas desde que los países se han concientizado del daño que sus industrias le ocasionan al medio ambiente. Gracias a este proceso de concientización ambiental han surgido puntos de encuentro internacionales que pretenden ser pioneros en la formulación de políticas alineadas al desarrollo sostenible, como la Conferencia de las Partes (COP). Este trabajo tiene como objetivo reflexionar sobre el papel de la COP en la política ambiental internacional, las deudas acumuladas con el ambiente y los retos en gobernanza global para lograr que los países cumplan con sus compromisos ambientales. A través de los años, los acuerdos en la COP han afrontado problemas para su implementación por parte de los miembros, llevando a la acumulación de deudas con el ambiente y una debilidad en la capacidad de gobernanza en el seno de la COP.
L'Allomorphie Radicale dans les Lexèmes Adjectivaux en Français: Le Cas des Adverbes en -ment
Authors: Boyé Gilles , Plénat Marc
Published: January 2023

This work describes the morphology of the French adverbs in -ment. Mainly derived from adjectives, these adverbs use various stem allomorphs as their base: most of them are built on a form identical to the adjective feminine form (SEC, fem. sèche: sèchement), but some endings favor the emergence of an /e/ (PROFOND, fem. profonde: profondément), while others select unpredictable allomorphs (BREF, fém. brève: brièvement). Finally, adjectives with -ent and -ant endings give adverbs in -emment and -amment (PRUDENT, fem. prudente: prudemment, ÉLÉGANT, fem. élégante: élégamment), except when an /m/ precedes these endings and the stem switches back to the feminine form (CHARMANT, fem. charmante: charmantement). It would seem futile to try and capture all of this diversity with only universal phonological constraints. A simple reason would be that the same phonemic sequences give rise to different results when constructing an adverb in -ment or a noun for an action from a deadjectival verb (while from INNOCENT and PRÉCIS French derives the adverbs innocemment and précisément, the verbs INNOCENTER and PRÉCISER give innocentement and précisement from the same phonological stems). And, moreover, because the adverbs obtained from nouns do not behave in the same way as the ones constructed on adjectives (for the adjective COLLANT, the adverb is collamment, but for the noun COLLANTS, the adverb is collantement). Our analysis revolves around the hypothesis that, in the lexicon, lexemes do not come equipped with a unique stem but with an indexed set of stems, each associated with specific inflectional cells and derivational constructs. In this framework (which produced new descriptions for the paradigms of adjectives, see Bonami and Boyé 2005, Plénat and Plénat 2011), adverbs are built on a stem inherited from the past or created by analogy (ACCUEILLANT and IMMONDE bring the neological accueillamment and immondément, based on ÉLÉGANT: élégamment and PROFOND: profondément). However, in one particular context, a universal constraint takes precedence over the analogical constraints and selects a different allomorph: this dissimilative constraint holds that a sequence of /m/ is infelicitous for the derivation of adverbs from adjectives in -ment/-mant which never give adverbs in -memment/-mamment but instead select the same stem as the feminine. Thus, adverbs in -ment provide an interesting interplay between parochial morphological stem selection preferences and universal phonological constraints.
Accentual Allomorphs in East Slavic: An Argument for Inflection Dependence
Authors: Steriade Donca , Yanovich Igor
Published: January 2023

This study analyzes a pattern of inflection dependence (Steriade 2008) in the distribution of accentual stem allomorphs in East Slavic, and it explores the significance of this pattern for the analysis of the phonological cycle. Inflected forms in Ukrainian and Russian surface with accented or unaccented stems as a predictable function of their inflectional class, the underlying accent of their root and further phonological factors. The result is that some lexemes possess multiple accentual stem allomorphs, others have invariably accented or invariably unaccented stems in inflection. We show that the derivatives of these lexemes use the full set of accentual stem allomorphs generated in the inflectional paradigm of their base, to optimize satisfaction of markedness and faithfulness conditions. The analysis requires a modification in the theory of Output-to-Output Correspondence (Benua 1998): in computing a derivative, the forms relative to which Faithfulness is assessed consist of the full set of inflected forms of the base item. In terms of the phonological cycle, the input to any cycle is a set of forms rather than just one form.

Published: January 2023

ABSTRACT Introduction: The physical condition of soccer players in sports competitions has improved over the years. The optimal performance of their professional skills in competitive conditions has become essential for victory in soccer matches. Objective: This paper explores the effects of different methods employing strength training on soccer kicking techniques aiming at the set that best enables the accuracy of hits through its stability. Methods: 36 soccer players were randomly divided into the experimental and control groups, with no statistical difference in fitness and the comprehensive ability characteristics of the players. Both subjects were trained for 12 weeks; only the experimental group received the special strength training intervention for stability. The passing score of the curve ball in 20-meter dribbling was measured before and after training. The data were statistically treated. Results: The kicking accuracy of soccer players in the experimental group differed from before the test (P<0.01). There was also a significant difference in kicking accuracy in the control group (P<0.05). The 20-meter arc dribbling scores in the experimental group were statistically significant compared to those before the test (P<0.05). There was no significant difference between the control group and the test scores on curve ball passing scores in 20-meter dribbling (P>0.05). Conclusion: Functional strength methods to achieve the goal of improving kicking accuracy in athletes have been developed. Coaches should pay attention to physical training, an attitude that encourages players to achieve sufficient physical strength for soccer games with their kicking skills.

Published: January 2023

ABSTRACT Introduction: The characteristics of basketball require excellent players with athletic abilities such as high explosive strength for the instantaneous jump up, flexible movements and quick changes of direction, and accurate passing and shooting. These characteristics can also be found in beach games, and it is believed that the practice of these games can benefit the practice of basketball. Objective: Explore the effect of beach training on the physical fitness of basketball players. Methods: Through a randomized controlled trial, 24 basketball players were selected to analyze the explosive power of the lower extremity in the 40m sprint race and in the vertical jump, two representative indicators of the explosive power of the lower limbs. The group teaching experiment was conducted for 17 weeks, five times a week. Results: The comparison in the statistical test of the 40m sprint, and the vertical jump before and after the experiment proves that, compared with the traditional practice of basketball, the practice of beach games has a beneficial effect on improving the explosive power of the lower limbs. Conclusion: Beach sports training has benefits for basketball practice; the characteristics on the beach basketball court and the playing characteristics of the athletes determined this.

Abstract The advancements in the cell culture studies have led to the development of regenerative medicine concept. The aim of this study is to compare the effectiveness of some washing solutions, including phosphate buffered saline (PBS), sodium chloride (NaCl), and ringer's lactate (RL) on the rate of detachment and confluency in fibroblast and osteoblast cell culture. Baby Hamster Kidney 21 clone 13 (BHK21/C13) fibroblast cells and 7F2 osteoblast were cultured on T25 flasks for 3-4 days. Three treatment groups were classified on the basis of different washing solutions used in the moment before trypsinization: PBS, 0.9% NaCl, and RL. Each group was measured for the detachment rate and cell confluence. The measurement was done in 2 passage numbers. The use of PBS, NaCl, and RL washing solution showed that detachment time was less than 5 minutes for the fibroblasts and 3 minutes for the osteoblasts. There was a significant difference in the rate of fibroblast cell detachment (p=0.006) and osteoblast (p=0.016). The capability of fibroblasts and osteoblasts to achieve a confluence of 106 cells/well on the first and second measurements was almost the same between the washing solution groups. The use of physiological 0.9% NaCl solution as a washing solution in fibroblast and osteoblast cell culture has almost the same effectiveness as PBS to help accelerate cell detachment in less than 5 minutes without influencing the capability of cells to proliferate.

ABSTRACT Anthropic activities in their various aspects have promoted soil degradation in the Brazilian semi-arid region (SAB). As a result, significant losses in productivity and in the ability of soils to fulfill their ecological functions have been reported. The present study investigated the effects of degradation on soil attributes and properties under dense (CAD) and sparse (CAE) shrubby Caatinga in Campina Grande, PB, Brazil. Samples from the 0-20 cm layer of soil were investigated via physical (particle size distribution and soil density), chemical (acidity, electrical conductivity, macronutrients, soil organic matter) and microbiological attributes (microbial biomass carbon (C-BMS), basal respiration of the soil (RBS) and metabolic quotient (qCO2) Data were submitted to the Mann-Whitney Test and Principal Component Analysis (PCA). Anthropic actions on the CAE promoted the exposure of the saprolitic layer on the surface. This layer has imperfect drainage, low levels of nutrients and organic matter and high sodicity, which contributes to the slow regeneration of vegetation. Carbon stock and microbial activity are significantly lower in CAE compared to CAD. Degradation resulted in losses of supporting ecosystem services (nutrient cycling and primary production) and regulation (erosion control and climate regulation). The results can be used to understand the dynamics of landscapes of low complexity (high degradation) in the SAB and serve as a framework to find strategies to restore the productive capacity of extensive degraded and/or desertified areas in the SAB.

ABSTRACT Brazil has advanced in export volume but has not been able to increase prices over the last decade for wood products. This work seeks to contribute to the understanding of this conflicting scenario, evaluating the growth in the revenue of Brazilian exports of these products during two periods: 2011-2015 and 2016-2020, as well as decomposing its effects in price, exchange rate, and volume. The method applied was the shift-share, widely used to identify determinants of sectoral and regional economic growth, being a precursor to the approach in the analysis of forest sector exports. Historical series for 5 (five) categories of wood products were analyzed, with export data from the Ministry of Economy. The historical series of nominal exchange rates from the Institute of Applied Economic Research (IPEA) was used. The real effective exchange rate (RER) followed the methodological note of the IPEA. All product categories analyzed had positive effects in terms of volume, for both periods, with a greater proportion in the second being driven by the exchange rate, although with a loss in real price, failing to offset inflation. The only exception was wood manufacturers, a product with higher added value, which presented gains in volume, exchange rates, and price. The volume effect was the most relevant, followed by the exchange rate as a result of the appreciation of the dollar against the real against the exchange rate and control of inflation in terms of the divergent effects on the national and international scenario. The price presented negative variations in export revenue, with a decline over the period. In addition to the added value of exported products, world stocks and levels of consumption may have contributed negatively to this scenario, affecting all categories of exported products, except for manufactured wood products, the only category that did not reflect such justifications.

Resumo: O presente artigo avalia a importância de algumas variáveis que influenciam a adoção de sistemas integrados de produção, em especial, os Sistemas Agroflorestais (SAFs), nos estabelecimentos agropecuários brasileiros. Com esse intento, utilizam-se dados em painéis agregados a nível de municípios e modelos da econometria espacial. Os dados são provenientes dos censos agropecuários referentes aos anos de 2006 e 2017. Os resultados do modelo SARAR apontam que a dimensão do rebanho bovino em um município associa-se negativamente com a adoção dos SAFs. De outro lado, ajuntam-se positivamente, com a adoção dos SAFs, a concessão do crédito rural, a associação do produtor à cooperativa ou entidade de classe, a maior presença de estabelecimentos direcionados à atividade econômica florestal, a maior ocorrência de produtor com idade de 45 anos em diante, maiores presenças de áreas com pastagens degradadas e de produtor com posse estável da terra, bem como maior frequência de estabelecimentos com adoção de boas práticas agrícolas. Adicionalmente, constataram-se maiores efeitos diretos do que os indiretos nos transbordamentos espaciais (entre municípios) das variáveis explicativas supracitadas.

ABSTRACT This study investigated the effects of dietary supplementation with Mansoa alliacea hydroalcoholic extracts on growth, blood and immune parameters of Arapaima gigas. Fish were fed for 30 days with diets enriched with 0, 4, 8, and 12 g kg-1 of M. alliacea hydroalcoholic extract and subjected to infection with Aeromonas hydrophila and handling stress. Fish fed with 8 g kg-1 of extract showed significant increase in final weight, specific growth rate and feed efficiency when compared to the other groups. Glucose, triglycerides, total proteins, and globulins increased significantly in fish fed with 8 g kg-1 of extract, whereas albumin decreased. The number of thrombocytes increased significantly with the dietary supplementation of 8 and 12 g kg-1 of extract. After the challenge with A. hydrophila and handling stress, fish fed with 8 g kg-1 of extract had significantly higher levels of glucose, globulins, and albumins, and fish fed with 8 and 12 g kg-1 of extract showed an increment of respiratory burst. Triglyceride levels dropped significantly in fish fed with 4, 8, and 12 g kg-1 of extract, whereas the number of neutrophils increased, and total thrombocytes, leukocytes and lymphocytes were higher in fish fed with 12 g kg-1 of extract. Dietary supplementation with M. alliacea extract at 8 g kg-1 was efficient in improving the growth and innate immunity of A. gigas, being potentially useful in fish farming to control the development of A. hydrophila infections.

Abstract: Introduction: The structure of educational methods is frequently renewed, using different available tools, according to the National Curriculum Guidelines. One of these, the realistic simulation (RS) methodology, is used to create proximity between the student and the real everyday life in a monitored environment, which provides room for error, but not with an actual patient. However, measuring meaningful learning is a complex task and support scales can be used. Based on this challenge, can the perpetuation of knowledge among students from different semesters using the RS tool add knowledge? Objectives: To explain the use of RS among medical students; to compare satisfaction and self-confidence indices in relation to RS using a scale, specifically in CPR (Cardiopulmonary Resuscitation), before and after the learning intervention among students from different semesters; to know the students’ learning process through the in-person teaching post-performance questionnaire. Method: This was a quasi-experimental study with 86 medical students from a private institution, with data collection was carried out in three stages, namely: study guidelines, scenario practice and perpetuation of knowledge to other students. Two questionnaires and an evaluation scale were used as tools and, for comparison, the relative and absolute frequencies, Cronbach’s alpha and the non-parametric Mann-Whitney test were used. Results: Cronbach’s alpha was considered high and the nonparametric test resulted in values between 3.81 and 4.91, indicating agreement in satisfaction and self-confidence in learning, with a significant difference in the answers: I liked the way my teacher taught using the simulation; I am confident that I have mastered the content of the simulation activity to which my teacher introduced me and I know how to use simulation activities to learn skills. Regarding the perpetuation of learning, its fixation and its relevance in training, all students also agreed that 6% still did not consider themselves ready to perform CPR. Conclusion: The study proposal proved to be effective in improving learning and perpetuating knowledge among students.
