Authors: Argollo Ferrão André Munhoz de , Torres Francisco Rodrigues 
Published: February 2022

O presente artigo pretende analisar reportagens que abordam o tema poluição na cidade de Cubatão, localizada no Estado de São Paulo, veiculadas durante a década de 1970, as quais foram fator preponderante para a construção de uma consciência ecológica. As reportagens abordadas permitem observar o aprofundamento da temática no decorrer dos anos, o envolvimento dos atores e seu empenho em divulgar seu ponto de vista, além de evidenciar a influência dos “mass media”, ou seja, os meios de comunicação, na elaboração de uma visão crítica. Há que se reconhecer que, para um entendimento menos reducionista, necessário se faz debruçar sobre a década de 1970, por ser possível observar os papeis representados pelos atores envolvidos. A análise do material jornalístico propicia que se revelem alguns processos que se desenrolam no território do município de Cubatão [SP], tais como o convívio de comunidades com efluentes, os jogos de poder, o silêncio das instituições, além das ações evidenciadas para divulgar ou dissimular os efeitos da poluição. A análise do material produzido nesse período possibilita reconhecer que os estudos realizados sobre meio ambiente, na região, devam ser tratados sob o enfoque do chamado “pensamento complexo”.

The Guiana dolphin (Sotalia guianensis) occurs in warm and shallow waters of the Atlantic Ocean and the Caribbean Sea, from southern Brazil to Honduras, including estuarine and freshwater habitats such as Maracaibo Lake (Venezuela), and the Orinoco River. In 2018, the Guiana dolphin was reclassified from Data Deficient to Near Threatened on the global IUCN Red List. Nevertheless, the conservation status identified by national and regional Red Lists is even more alarming. In French Guiana, for example, the species is classified as Endangered based on strong pressures such as bycatch. In this region, the Guiana dolphin inhabits river mouths and coastal waters where most anthropogenic activities occur. Better knowledge of the biology and ecology is needed in French Guiana to help inform effective conservation actions. Here, we present ongoing studies to map the distribution of Guiana dolphins along the French Guiana coast and estimate abundance in a hotspot area. Aerial survey campaigns were conducted during the dry season in 2013, 2014, 2015, and 2019. Eight flights were conducted and 146 dolphins belonging to 39 groups were observed. Boat-based line-transect surveys were also conducted in the coastal waters of Cayenne in 2017 and 2018. Twenty-one survey trips were conducted covering 999.06 km. Three hundred and eighty-two dolphins belonging to 63 groups were observed. The total abundance in the Cayenne area was estimated at 128 dolphins (% CV = 30.92; CI (95%) = 70-235) with a density of 0.80 ind./km² (% CV = 30.92; CI (95%) = 0.44-1.47). Additionally, a descriptive analysis was performed on stranding data collected in French Guiana between 2014 and 2020 to identify the major cause of death and seasonality in the stranding events. In total, 43 dolphins were found, especially on the beaches of Rémire-Montjoly, Cayenne, and Kourou: bycatch was the major identifiable cause of death. We recommend a local conservation strategy and actions to be undertaken in the short- and medium-term to address different issues: knowledge, threats, conservation, and cooperation.
Two new remarkable and endangered catfish species of the genus Cambeva (Siluriformes, Trichomycteridae) from southern Brazil
Authors: Costa Wilson J.E.M. , Feltrin Caio R.M. , Katz Axel M. 
Published: February 2022

During a field inventory directed at trichomycterine habitats, two new species of the genus Cambeva, C. alphabelardense sp. nov. and C. betabelardense sp. nov., were found in the Rio Chapecó drainage, an area under high environmental decline due to intensive soya monoculture. These species share a peculiar head morphology and some unique osteological features, besides having a size that is smaller than in any other congener, being herein considered to be more closely related to each other than to other taxa. They differ from each other by several characters, including head shape, fin morphology, number of jaw teeth and opercular odontodes, and mesethmoid and metapterygoid shape. Furthermore, they were found in the same area, but in distinct biotopes, with one species found buried in the remnants of tree ferns and other plants on the stream bottom, restricted to a small residual fragment of the original forest, and the other species inhabiting a stream with gravel and small stones on the bottom. Field studies indicate that these species are threatened with extinction. Robust phylogenetic studies are still necessary to test relationship hypotheses involving the new taxa here described.

Background: Dermatoglyphics is an essential tool in population studies, identification of persons and diagnosis of diseases of genetic origin. The aim of the study was to determine the characteristics of finger dermatoglyphic patterns peculiar to Uturu indigenes of Abia State.
Materials and Methods: The study was conducted among the Uturu Indigenes of Isikwuato Local Government Area of Abia State Nigeria. A total of two hundred (200) volunteers comprising 100 Males (M) and 100 Females (F) participated in the study. The fingerprints of the thumb (I), index finger (II), middle finger (III), ring finger (IV) and little finger (V) were obtained from the right and left hands using digital scanners and computers. Data were obtained for finger dermal patterns, finger ridge count (FRC) and total finger ridge count (TFRC) Analysis of data was done using Microsoft Excel Data Analysis Tool pack (2016 Edition) and Chi Square test at p>0.05 was used to determine sexual dimorphism and bilateralism.
Results: The patterns observed among sampled Uturu indigenes were Arch (AR), Central pocket loop (CP.L), Double loop (DL), Spiral whorl (SP.W), Ulnar whorl (UL). Uturu people have more ulnar loops in both hands [I; (Right; R) = 55%, (Left; L = 58%), II; (R = 60%, L = 59.5%), III; (R = 75%, L = 66%), IV; (R = 63%, L = 64%), V; (R = 85%, L = 83.5%)], followed by whorls [I; (R = 25%, L = 21.5%), II; (R = 26%, L = 23%), III; (R = 18.5%, L = 20%), IV; (R = 24.5%, L = 25%), V; (R = 9%, L = 9.5%)] and arches [I; (Right; R) = 9.5%, (Left; L) = 12.5%, II; (R = 11%, L = 12.5%), III; (R = 4%, L = 9%), IV; (R = 3%, L = 3.5%), V; (R = 2.5, L = 3.5%)], while radial loop was the least observed pattern (1.5% on the left index finger). The test for bilateralism showed no significant difference in the distribution of dermal patterns in the right and left fingers. In the index finger, significant difference (P>0.05) was observed in the pattern distribution for the right between males and females. Uturu indigenes have more finger ridge count in the right thumb.

Aims: The objective of this study is to determine the physicochemical characteristics, functional properties, antioxidant and anti-nutrient activities of pulp powders of Safou (Dacryodes edulis var edulis) according to cooking methods in order to promote their consumption for food security.
Study Design: Biochemical and technological studies.
Place and Duration of Study: Laboratory of Biocatalysis and Bioprocessing, Abidjan, Côte d’Ivoire.
Methodology: Three different Safou powders were prepared (PSS, PSV and PSEB). PSS (Safou pulp was not cooked before drying); PSV (Safou pulp was steamed before drying) and PSEB (Safou pulp was cooked in hot water before drying). The determination of the physicochemical characteristics concerned rates of dry matter, ashes, proteins, lipids, carbohydrates and energy value. The determination of the functional properties concerned water and oil capacity, water solubility index, bulk density, porosity, wettability, foaming capacity, hydrophilic-lipophilic ratio, swelling, solubility, foam stability and dispersibility. The determination of antioxidant and anti-nutrient activities concerned total polyphenols, tannins, DPPH, iron reducing power, total oxalates and phytates.
Results: Uncooked Safou pulp powders (PSS) are good sources of protein, ash, lipid and polyphenols. Cooking improved carbohydrate and energy values and the functional properties and lowered the anti-nutritional factors of Safou pulp powders.
Conclusion: The different cooking methods applied to the Safou pulp had an influence on the contents of nutrients. The powder of Safou cooked in boiling water (PSEB) showed the best functional properties and lowered the anti-nutrient factors. It could be recommended for the enrichment of local infant flours.

Published: February 2022

Chitin is most abundantly found non-digestible carbohydrate similar to cellulose. It has gained a lot of interest in last few years due to its wide range of applications. They are used as an alternative, dietary supplement. Chitin on deacetylation forms chitosan, an active component of chitin. The degree of deacetylation and molecular weight are the factors that elucidate varying degree of biological property of chitosan. The ability of chitosan in fat and lipid excretion has obtained keen eye among various researchers. This property of chitosan is made use in enhancing the elimination of various harmful environmental lipophilic xenobiotics. Endocrine disruptors are a group of environmental pollutants causing various hazardous effects in living system. They are highly lipophilic, persistent and can accumulate in various tissues. Thus correlating the ability of chitosan to increase excretion of fats and lipophilic xenobiotics showed a promising positive outcome.

AbstractPurposeThe purpose of this work is to evaluate the Hyperscint‐RP100 scintillation dosimetry research platform (Hyperscint‐RP100, Medscint Inc., Quebec, QC, Canada) designed for clinical quality assurance (QA) for use in in vivo dosimetry measurements.MethodsThe pre‐clinical evaluation of the scintillator was performed using a Varian TrueBeam linear accelerator. Dependency on field size, depth, dose, dose rate, and temperature were evaluated in a water tank and compared to calibration data from commissioning and annual QA. Angularity was evaluated with a 3D printed phantom. The clinical evaluation was first performed in two cadaver dogs, and then in three companion animal dogs receiving radiation therapy for nasal tumors. A treatment planning CT scan was performed for cadavers and clinical patients. Prior to treatment, the probe was inserted into the radiation field. Radiation was then delivered and measured with the scintillator. For cadavers, the treatment was repeated after making an intentional shift in patient position to simulate a treatment error.ResultsIn the preclinical measurements the dose differed from annual measurements as follows: field size −0.77 to 0.43%, depth dose −0.36 to 1.14%, dose −0.54 to 2.93%, dose rate 0.3 to 3.6%, and angularity −1.18 to 0.01%. Temperature dependency required a correction factor of 0.11%/°C. In the two cadavers, the dose differed by −1.17 to 0.91%. The device correctly detected the treatment error when the heads were intentionally laterally shifted. In three canine clinical patients treated in multiple fractions, the detected dose ranged from 98.33 to 103.15%.ConclusionResults of this new device are promising although more work is necessary to fully validate it for clinical dosimetry.

Published: February 2022

AbstractThis article presents an ultrathin, broadband, and multipurpose polarization converter design utilizing an anisotropic metasurface for K and Ka band. The proposed polarization converter, which has a single layer F4B as a substrate material with hexagonal‐shaped metallic solid structure along with hexagonal ring with diagonal splits on its front surface and a background (a completely metallic surface) on its back, works as not only a circular polarization converter but also a linear polarization to circular polarization (LP to CP) converter. Its polarization conversion rate (PCR) is more than 90% in the frequency range from 17.87 to 43.15 GHz, covering all of the K and Ka bands with a relative bandwidth of 83% under normal incidence case. For incidence angles up to 40°, PCR is observed to be greater than 75% in almost all of the K and Ka bands (except for the frequency range between 24.72 and 27.11 GHz). Furthermore, the proposed design has LP to CP in two different frequency bands, 16.23–16.74 GHz and 48.6–48.8 GHz. The proposed polarization converter, as advantages, is low cost, ultra thin, broadband, and facile, which can be useful in linear cross polarization conversion in K and Ka band applications.
The Transient Response of Organic Electrochemical Transistors

Published: February 2022

AbstractA fast response of organic electrochemical transistors (OECTs) to electrical or chemical changes is essential for a widespread acceptance of this technology. However, finding design rules for fast switching OECTs is complicated by the fact that current transient device models are highly simplified and rely on a 1D approximation of the device that neglects details of the ion and hole concentration inside the transistor channel. To improve the understanding of transient processes limiting the speed of OECTs, a 2D drift‐diffusion model is presented and experimentally validated. It is shown that switching is strongly influenced by lateral ion currents that are neglected in previous models. A consistent treatment of these currents leads to a dependency of the time constants on the applied drain potential and a complex dependency of the response time constants on the detailed device geometry. In addition to an improved understanding of the transient response of OECTs, the results discussed here highlight the challenges in properly characterizing switching time constants of OECTs, and reinforce the necessity to ensure that switching is measured between two steady‐state conditions, and not between transient states.
Mechanically Resistant Poly(N‐vinylcaprolactam) Microgels with Sacrificial Supramolecular Catechin Hydrogen Bonds
Authors: Izak‐Nau Emilia , Braun Susanne , Pich Andrij , Göstl Robert 
Published: February 2022

AbstractMicrogels (μgels) swiftly undergo structural and functional degradation when they are exposed to shear forces, which potentially limit their applicability in, e.g., biomedicine and engineering. Here, poly(N‐vinylcaprolactam) μgels that resist mechanical disruption through supramolecular hydrogen bonds provided by (+)‐catechin hydrate (+C) are synthesized. When +C is added to the microgel structure, an increased resistance against shear force exerted by ultrasonication is observed compared to μgels crosslinked by covalent bonds. While covalently crosslinked μgels degrade already after a few seconds, it is found that μgels having both supramolecular interchain interactions and covalent crosslinks show the highest mechanical durability. By the incorporation of optical force probes, it is found that the covalent bonds of the μgels are not stressed beyond their scission threshold and mechanical energy is dissipated by the force‐induced reversible dissociation of the sacrificial +C bonds for at least 20 min of ultrasonication. Additionally, +C renders the μgels pH‐sensitive and introduces multiresponsivity. The μgels are extensively characterized using Fourier‐transform infrared, Raman and quantitative nuclear magnetic resonance spectroscopy, dynamic light scattering, and cryogenic transmission electron microscopy. These results may serve as blueprint for the preparation of many mechanically durable μgels.

Published: February 2022

AbstractRepeatability and high adhesion toughness are usually contradictory for common polymer adhesives. Repeatability requires temporary interactions between the adhesive and the substrate, while high adhesion toughness is usually achieved by permanent bonding. Integrating these two features into one adhesive system is still a daunting challenge. Here, the development of a series of viscoelastic elastomers composed of a soft and hard segment is reported, which exhibit tough, instant, yet repeatable adhesion to a variety of soft and hard surfaces. Such a combination of mutually exclusive properties is attributed to the synergy of high mobility of polymer chains and massive viscoelastic dissipation of the elastomers around the interface. By optimizing the relaxation time and mechanical dissipation, the resulting adhesives can achieve a tough yet repeatable adhesion toughness above 2000 J m−2, superior to the best‐in‐class commercial adhesives. Numerous acrylate monomers are proven applicable to the preparation of such adhesives, validating the universality of the fabrication method. The application of these elastomers as adhesive and protective layers in soft electronics by virtue of their universal and tough adhesion to various soft and hard substrates is also demonstrated.
