Do videoclipe ao romance
Authors: Bezerra Silvia de Paula
Published: August 2021

Lecionar literatura no Ensino Médio é um trabalho gratificante e desafiador, que precisa estar aliado à pesquisa e à atualização constante por parte dos docentes. Consoante esta premissa, e partindo de experiência em sala de aula, este trabalho busca mostrar como o uso da intermidialidade, conforme definida por Clüver (2006), pode ser uma estratégia didática eficiente, uma vez que o autor trata das relações intertextuais que perpassam todas as linguagens artísticas. Como corpus, utiliza-se o videoclipe da canção Amor, I love you (2000), de Marisa Monte e Carlinhos Brown, e a leitura de um trecho da obra O primo Basílio (1878), de Eça de Queirós, além do que pontua Tereza Colomer (2007), a respeito das diferentes possibilidades de aproximação com o texto literário e Roxane Rojo (2009) acerca da necessidade de associar, sempre que possível, o texto verbal escrito a outras formas de expressão.
Modelagem Geométrica de Fachadas usando Nuvens de Pontos LiDAR
Authors: Sousa Luís Antônio Soares e , Centeno Jorge Antônio Silva
Published: August 2021

LiDAR se mostrou valioso na análise do meio urbano, pois permite a captura de informações tridimensionais para detectar e modelar edifícios. O desenvolvimento do LiDAR móvel terrestre abriu novas possibilidades para a modelagem 3D em áreas urbanas. Neste artigo é apresentada uma metodologia semiautomática que visa calcular modelos tridimensionais de edifícios a partir de nuvens de pontos obtidas com LiDAR terrestres móveis. Para tanto, a nuvem de pontos é segmentada em blocos de planos uniformes analisando a variação da densidade de pontos ao longo das principais direções da fachada. Isso permite segmentar a nuvem de pontos em regiões planas que posteriormente são combinadas para construir o modelo 3D, mesmo quando a fachada possui diferentes planos paralelos. O principal diferencial da metodologia é a utilização dos histogramas de frequência para segmentar a nuvem de pontos e detectar as bordas da fachada, garantindo economia de tempo em relação aos métodos tradicionais.

A partir dos anos 2000, houve um aumento na aquisição de dados LiDAR (Light Detection and Ranging) em áreas urbanas, o que possibilitou diversos estudos e aplicações nas mais variadas áreas, verificando-se um crescimento dos acervos históricos. Com isso, são necessários métodos de processamento robustos para manipulação desses dados. Os métodos de registro de dados laser inserem-se nesse contexto, essenciais para promover a utilização de dados oriundos de distintos equipamentos e datas. Este estudo consiste em avaliar o desempenho de três métodos de registro: Iterative Closest Point (ICP), Coherent Point Drift (CPD) e Support Vector Registration (SVR). A metodologia contempla o pré-processamento dos dados LiDAR para a extração de três telhados de edifícios com características distintas, localizados no campus da UFPR, em Curitiba – PR. Foram utilizados dados do sensor Optech ALTM Pegasus HD 500, com frequência de 300 kHz e altura de voo de 1.600 m, densidade média de 1,71 pontos por m² e IFOV de 25°. Os métodos foram implementados na linguagem Python. Como resultados, foram obtidos os registros, dos quais foram extraídas suas acurácias e tempos de processamento. Os resultados evidenciaram que os métodos CPD e SVR são ótimas alternativas para superar as limitações do ICP, ressaltando-se o desempenho do CPD e a eficiência computacional do SVR, sendo que este último é particularmente adequado para lidar com dados ruidosos.

Metamorfoses: deslocamento e pertencimento em “Tudo são histórias de amor”, de Dulce Maria Cardoso
Authors: Fonseca e Silva Larissa
Published: August 2021

Neste artigo, propõe-se uma leitura do conto “Tudo são histórias de amor”, da autora portuguesa Dulce Maria Cardoso, a partir de suas múltiplas camadas textuais, entendendo-as como partes do processo de (re)construção do sujeito que narra. A narradora, que se apresenta como Jinja, uma ex-cadela de rua, diz ter “entrado na cabeça” de Dulce quando esta escrevia um texto sobre Lisboa, o “Metamorfoses”. Jinja e Dulce, dividindo a voz, também se identificam à própria Dulce Maria Cardoso, que se insere no texto a partir de índices autobiográficos referentes à sua vivência do exílio, tendo sido “retornada”. A narradora, então, sendo aqui descrita como um sujeito fragmentado, deslocado e descentralizado (HUTCHEON, 1991; SAID, 2004; HALL, 2006), usa de diversas estratégias literárias para escrever sobre as “dimensões simultâneas” (SAID, 2003, p. 59) que experencia ao mesmo tempo em que passa a pertencer a Lisboa.

Hybrid Inception Recurrent Residual Convolutional Neural Network (HIRResCNN) with Harmony Search Optimization (HSO) for Early Breast Cancer Detection System
Authors: Sangeetha K. , Prakash S.
Published: August 2021

For women, most common cause of death is Breast tumour and in worldwide, it is the second leading reason for cancer deaths. Due the requirement of breast cancer’s early detection and false diagnosis impact on patients, made researchers to investigate Deep Learning (DL) techniques for mammograms. There are four stages in this proposed HIRResCNN framework, namely, Pre-processing, reduction of dimensionality, segmentation and classification. From images, noises are removed using two filtering algorithms called Median and mean filtering in pre-processing stage. Then canny edge detector is used for detecting edges. Gaussian filtering is used in canny edge detector to smoothen the images. In the next dimensionality reduction stage, attributes are correlated using Principal Component Analysis (PCA) inclusive of related features. So, this huge dataset is minimized and only few variables are used for expressing it. In order to detect the breast cancer accurately, foreground and background subtraction is done in the third stage called segmentation stage. At last, for detecting and classifying breast cancer, a Hybrid Inception Recurrent Residual Convolutional Neural Network (HIRResCNN) is introduced, which integrates Harmony Search Optimization (HSO) to tune bias and weight parameters and classification accuracy is enhanced using HIRResCNN-HSO model. Strength of Recurrent Convolutional Neural Network (RCNN), Residual Network (ResNet) and Inception Network (Inception-v4), are combined in a powerful Deep Convolutional Neural Network (DCNN) model called HIRResCNN. using Mammographic Image Analysis Society (MIAS) dataset, various experiments are conduced and results are compared with other available techniques. Around 92.6% accuracy rate is produced using this proposed HIRResCNN classifier in finding breast cancer.

Authors: Alkhafaji Mohammed Nawfal Abdul Maged , Hussain Hutham Abd Ali Abd Al , Aljamali Dr. Nagham Mahmood
Published: August 2021

Imidazoles are part of the theophylline Reagent, found in tea leaves and coffee beans, which stimulates the central nervous system. It is found in the anti-cancer drug mercaptopurine, which fights leukemia by interfering with DNA systems. A number of prepared imidazoles, including clotrimazole, are selective inhibitors of nitric oxide synthase, which makes them interesting drug targets in inflammation, respiratory diseases and tumors of the nervous system. Other biological activities of the drug carrier imidazole relate to deregulation of the intracellular fluxes of (Ca and K) ions. Novel imidazole –heterocyclic reagents were created via cyclization process then condensation process., followed by investigation of all created new reagents via a number of spectral performances (FT.IR, H.NMR)–spectrophotometric, other physical and chemical properties, and chromatographic study with microbial studying for all new created imidazole reagents.

Authors: Mustafa Yasser Fakri , Abdulaziz Noora Thamer
Published: August 2021

Brain cancer is the 10th cause of death among patients suffering from cancer worldwide. Despite the huge effort put out to extract, design, and synthesize novel chemotherapeutic drugs, medicinal chemists continue to face significant obstacles due to considerable side effects, growing tumor resistance, and poor selectivity. In recent decades, great attention has been paid to the anti-cancer potential of a variety of natural compounds. Coumarin-based compounds, for example, are distinguished by their structural variety and wide range of pharmacological characteristics. Among these, hymecromone, also known as 7-hydroxy-4-methylcoumarin, and its derivatives have shown promise in the treatment of multi-drug cancer resistance, the decrease of chemotherapeutic drug side effects, and the creation of photo-directed cancer therapy. Furthermore, numerous synthetic hymecromone-derived compounds have been demonstrated to have a broad antitumor potential, making them effective against a variety of cancers including leukemia, prostate cancer, lung cancer, breast cancer, and brain cancer. In this review article, the authors evaluated the findings of a number of recently published scientific studies in order to emphasize the structural properties of hymecromone-derived compounds that are crucial in their potential as antitumor agents for brain cancer. The specification of these qualities might help guide future research towards the design and synthesis of newer chemotherapeutic drugs with improved features.

Le vocabulaire du tourisme, un laboratoire expérimental des procédés néologiques
Authors: Tallarico Giovanni
Published: August 2021

The vocabulary of tourism has not been studied in depth until recently. In this paper we try to fill this gap, by focussing on French neologisms attested in this field. Our research, based on Timestamped JSI web corpus (2014-2019), shows that word formation largely stems from binomial appositions, thus following the model of terminology. A comparatively small number of words consist on translations from English, since French tourism is deeply rooted in national culture.
Can multi-stakeholder forums influence good governance in communal forest management? Lessons from two case studies in Ethiopia
Authors: Yami M. , Barletti J.P. Sarmiento , Larson A.M.
Published: August 2021

Following global trends, Multi-Stakeholder Forums (MSFs) have received attention as mechanisms for addressing deforestation and forest degradation in Ethiopia. However, little is understood on their influence on governance of forests. Based on qualitative research conducted in MSFs
organized at Bale and Jamma-Urji in Oromia, Ethiopia, this paper examines how MSFs may influence the governance of communal forests. Results indicate that the majority of informants believe that MSFs improve participation, facilitate collaboration across sectors, and have potential to address
power imbalances among stakeholders. Yet, failing to substantially engage the government in MSFs could either lower the success of the MSFs in bringing change in the governance of communal forests or limit the changes to the local community level. Embedding MSFs in government structures could
increase the enforcement of MSF outcomes and enable resource mobilization. However, caution is required to prevent the government's control over MSF processes and outcomes.
Organizing for transformation? How and why organizers plan their multi-stakeholder forums
Authors: Barletti J.P. Sarmiento , Larson A.M. , Vigil N. Heise
Published: August 2021

Multi-stakeholder forums (MSFs) have received much attention from policymakers and development and conservation practitioners as a transformative solution for more equitable coordination and decision-making over environmental challenges. Studies on "invited spaces" have previously shown
the importance of balancing power relations and attending to context. To what extent do the plans and expectations of MSF organizers reflect these previous lessons? This paper examines how and why the organizers of 13 subnational MSFs addressing sustainable land and resource management in
Brazil, Ethiopia, Indonesia and Peru established these forums, and if and how their plans and expectations compare to previous lessons on invited spaces. Findings reveal that the organizers conceived of power inequalities as obstacles that could be overcome by including historically disempowered
peoples in the MSFs, but generally failed to consider specific measures to address inequalities; nor did they develop clear strategies to engage with unsustainable local development and political priorities.

Preparation and characterizations of antibacterial–antioxidant film from soy protein isolate incorporated with mangosteen peel extract
Authors: Zhou Xin , Dai Qingyin , Huang Xi , Qin Zhiyong
Published: August 2021

The mangosteen peel extract (MPE) was used to obtain soy protein isolate (SPI) films. The results show that MPE exhibited a high content of total phenolics and antioxidant activity. Moreover, the MPE can enhance the antibacterial–antioxidant properties, UV-visible light barrier properties, and water-resistant properties of the SPI films. The presence of MPE resulted in an increase in water vapor permeability and hydrophobicity. The extract addition also reduced the film’s crystallinity along with a decrease in the mechanical property and lowering of the maximum degradation temperature. Attenuated total reflectance Fourier transform infrared spectroscopy revealed that the polyphenols in MPE could interact with SPI through hydrogen bonds and hydrophobic interactions, and the addition of MPE changed the secondary structure of SPI with a decrease in β-sheets and an increase in β-turns and random coils. Scanning electron microscopy showed that all the films exhibited smooth and homogenous morphology on the surface and on some layers through cross-sectional images. Our results suggested that the MPE would be a promising ingredient to make SPI films used as an active packaging material.
Algebro-geometric integration of a modified shallow wave hierarchy
Authors: He Guoliang , Zhai Yunyun , Zheng Zhenzhen
Published: August 2021

By introducing two sets of Lenard recursion relations, we derive a hierarchy of modified shallow wave equations associated with a 3 × 3 matrix spectral problem with three potentials from the zero-curvature equation. The Baker–Akhiezer function and two meromorphic functions are defined on the trigonal curve which is introduced by utilizing the characteristic polynomial of the Lax matrix. Analyzing the asymptotic properties of the Baker–Akhiezer function and two meromorphic functions at two infinite points, we arrive at the explicit algebro-geometric solutions for the entire hierarchy in terms of the Riemann theta function by showing the explicit forms of the normalized Abelian differentials of the third kind.

Authors: Rajagopal Karthikeyan , Duraisamy Prakash , Tadesse Goitom , Volos Christos , Nazarimehr Fahimeh , Hussain Iqtadar
Published: August 2021

In this research, the ship power system is studied with a fractional-order approach. A 2-D model of a two-generator parallel-connected is considered. A chaotic attractor is observed for particular parameter values. The fractional-order form is calculated with the Adam–Bashforth–Moulton method. The chaotic response is identified even for the order 0.99. Phase portrait is generated using the Caputo derivative approach. Wolf’s algorithm is used to calculate Lyapunov exponents. For the considered values of parameters, one positive Lyapunov exponent confirms the existence of chaos. Bifurcation diagrams are presented to analyze the various dynamical behaviors and bifurcation points. Interestingly, the considered system is multistable. Also, antimonotonicity, period-doubling, and period halving are observed in the bifurcation diagram. As the last step, a fractional-order controller is designed to remove chaotic dynamics. Time plots are simulated to show the effectiveness of the controller.

(Mis) perception of consonant clusters and short vowels in English as a foreign language
Authors: Leung Alex Ho-Cheong , Young-Scholten Martha , Almurashi Wael , Ghadanfari Saleh , Nash Chloe , Outhwaite Olivia
Published: August 2021

Research addressing second language (L2) speech is expanding. Studies increasingly demonstrate that a learner’s first language (L1) filters the L2 input, resulting in learners misperceiving what they have heard. This L1 filter can result in learners perceiving sounds not actually present in the input. We report on a study which explored English consonant clusters and short, unstressed vowel perception of 70 Arabic-, Mandarin-, Spanish-speaking foreign language learners and 19 native English speakers. These are the vowels which speakers from two of the L1s typically insert in their production of English to break up L1-disallowed consonant clusters and the schwa which is documented to cause both perception and production problems. Results show that participants misperceive stimuli containing consonant clusters and counterparts where clusters are broken up by epenthetic/prothetic elements. In line with Sakai, Mari & Colleen Moorman 2018. We call for the inclusion of such findings on perception in pedagogical advice on pronunciation.
Diet and activity pattern of leopard in relation to prey in tropical forest ecosystem
Authors: Palei Himanshu Shekhar , Pradhan Tilak , Sahu Hemanta Kumar , Nayak Anup Kumar
Published: August 2021

Understanding the predator–prey relationship is essential for implementing effective conservation management practices on threatened species. Leopard is a threatened apex mammalian predator that plays a crucial role in ecosystem functions in India’s tropical forest. We assessed the diet and activity pattern of leopards in relation to their prey using diet analysis and camera trapping data from Similipal Tiger Reserve, eastern India. Our results indicated that leopard prefers medium-sized prey such as wild pig, common langur and barking deer represented 60% of the total biomass consumed collectively. Results of 6413 camera trap night in 187 locations revealed that leopards showed cathemeral activity pattern and exhibited positive co-occurrence pattern and significant spatial and temporal overlap with their main prey, the wild pig. However, leopards showed very low spatial and temporal overlap with the second main prey, the common langur. Leopards avoided humans and showed low spatial and temporal overlap with humans. Our findings reveal that a trade-off might drive leopard activity between consuming prey and avoiding anthropogenic disturbances like human activity.

A zoosemiotic approach to the transactional model of communication
Authors: Cerrone Mirko , Mäekivi Nelly
Published: August 2021

The analysis of social communication in other-than-human animals poses several theoretical challenges due to the complexity of individual and extra-individual variables. Some previous studies have found a valuable solution in Uexküll’s work by expanding and adapting its usage for the study of communication in a heurtistic manner. An Umwelt analysis provides a theoretical toolbox, which allows researchers to take an emic perspective on the lives and phenomenal world of other animals. However, Umwelt and its elaborations do not allow for a clear distinction between acts of perception and communication and seem to ignore factors that escape the specific communication contexts under analysis. Thus, moving away from the existing linear and cyclical approaches to communication, we propose a complementary approach to the study of social communication by combining Barnlund’s transactional model of communication with Umwelt theory and the functional circle more specifically. Our elaborated model conceives social communication as the process of creating meaning through the interaction of two (or more) subjects and emphasizes the role of species-specific and individual features in its creation. Our goal is to re-evaluate the research on social communication of other-than-human animals by advocating for the theoretical and empirical potential of Umwelt, especially pertaining to animals with complex Umwelten. Our model offers a valuable solution to the analysis of intraspecies communication that accounts for the role of private and public cues as well as the subjects’ specific behaviors, messages, and context in the creation of meaning.
State price density estimation with an application to the recovery theorem
Authors: Sanford Anthony
Published: August 2021

This article introduces a model to estimate the risk-neutral density of stock prices derived from option prices. To estimate a complete risk-neutral density, current estimation techniques use a single mathematical model to interpolate option prices on two dimensions: strike price and time-to-maturity. Instead, this model uses B-splines with at-the-money knots for the strike price interpolation and a mixed lognormal function that depends on the option expiration horizon for the time-to-maturity interpolation. The results of this “hybrid” methodology are significantly better than other risk-neutral density extrapolation methods when applied to the recovery theorem.

Stance in press releases versus business news: a lexical bundle approach
Authors: De Cock Sylvie , Granger Sylviane
Published: August 2021

Press releases represent a hybrid business genre, which combines an informational and a promotional communicative purpose. The objective of the study is to assess the extent to which this duality is reflected in the language used, and more particularly in the expression of stance, by comparing corporate press releases with another business genre that is essentially informational, namely business news reporting. The focus is on lexical bundles, as they have been found to be a major conveyor of attitudinal and epistemic stance. Relying on the pattern-matching approach to language, 3-word lexical bundles are extracted from a 1-million-word corpus of press releases (BeRel) and set against those found in a similar-sized corpus of business news (BeNews). An examination of the key bundles (keyword analysis) in each corpus reveals that the bundles that are distinctive to press releases differ significantly from those found in BeNews, particularly in the expression of modal, evaluative and personal stance.
A comparative study between lateral internal anal sphincterotomy and botulinum toxin injection in the treatment of chronic anal fissure
Authors: Zngana Abdulqadir , Hiwa Bawan
Published: August 2021

Background and objective: The gold standard for the treatment of chronic anal fissure is lateral internal sphincterotomy. Botulinum toxin injection provides temporary alleviation of sphincter spasm and allows the fissure to heal. This study aimed to compare the outcomes of lateral internal sphincterotomy and botulinum toxin injection treatments in patients with uncomplicated chronic anal fissure. Methods: A prospective comparative study was carried out at the surgical unit of Erbil teaching hospital, Erbil, Kurdistan Region of Iraq, from January 2017 to February 2018. Fifty-five patients were enrolled in this study. Five patients were excluded, and the remaining 50 patients were equally divided into two groups. Group A was managed with lateral internal sphincterotomy and group B with botulinum toxin. Postoperative pain relief, bleeding, fissure healing, incontinence, and relapse after six weeks and three months of follow-up were compared. Results: One month after treatment, 12% of the lateral internal sphincterotomy group had bleeding, while none of the botulinum toxin group (P = 0.234). Two patients (8%) of the lateral internal sphincterotomy group had pain while one (4%) of the botulinum toxin group (P >0.999).Three months after treatment, 4% of the lateral internal sphincterotomy group had bleeding, while none of the botulinum toxin group (P >0.999). None of the lateral internal sphincterotomy group had pain while one (4%) of the botulinum toxin group (P >0.999). Regarding healing, 96% of the lateral internal sphincterotomy group healed, while 92% in the botulinum toxin group (P >0.999). Conclusion: The outcome of lateral internal sphincterotomy and botulinum toxin were nearly the same, but lateral internal sphincterotomy required hospitalization, period off work, and risk of anesthesia. These risks were absent in botulinum toxin injection. Keywords: Chronic anal fissure; Lateral internal sphincterotomy; Botulinum toxin; Complications.

Background and objective: Antacids are basic substances that can neutralize hydrochloric acid and reduce gastric acidity. They are over the counter drugs used to treat dyspepsia. The most commonly used antacids are sodium bicarbonate, magnesium hydroxide, aluminum hydroxide, and calcium carbonate. This study aimed to evaluate the effectiveness of antacids that are commonly used in Erbil city by finding their acid-neutralizing capacity. Methods: The method for acid-neutralizing capacity was adapted from pharmacopeia. The samples were prepared by dissolving the antacid in an excess amount of hydrochloric acid, then neutralizing the excess acid with sodium hydroxide solution by doing back titration. The number of milliequivalents that are neutralized by the antacid is the acid-neutralizing capacity of the antacid. Results: Rennie® chewable tablet showed the highest acid-neutralizing capacity, followed by AntacidAwa and Maalux® plus. The lowest acid-neutralizing capacity was for the suspensions Gaviscon® and Enoxon®. Conclusion: Acid-neutralizing capacity is an easy and quick method to evaluate the efficacy of antacids. Different combinations of salts and concentrations can affect the acid-neutralizing capacity of the antacid. The higher the neutralizing effect of the antacid, the more effective the antacid is. Keywords: Acid-neutralizing capacity; Antacid; pH; Dyspepsia; Erbil.
The Mammalian Olfactory Bulb Contributes to the Adaptation of Odor Responses: A Second Perceptual Computation Carried Out by the Bulb
Authors: Storace Douglas A. , Cohen Lawrence B.
Published: August 2021

While humans and other mammals exhibit adaptation to odorants, the neural mechanisms and brain locations involved in this process are incompletely understood. One possibility is that it primarily occurs as a result of the interactions between odorants and odorant receptors on the olfactory sensory neurons in the olfactory epithelium. In this scenario, adaptation would arise as a peripheral phenomenon transmitted to the brain. An alternative possibility is that adaptation occurs because of processing in the brain. We made an initial test of these possibilities using a two-color imaging strategy to simultaneously measure the activity of the olfactory receptor nerve terminals (input to the bulb) and mitral/tufted cell apical dendrites (output from the bulb) in anesthetized and awake mice. Repeated odor stimulation at the same concentration resulted in a decline in the bulb output, while the input remained relatively stable. Thus, the mammalian olfactory bulb appears to participate in generating the perception of olfactory adaptation under this stimulus condition. Similar experiments conducted previously showed that the bulb may also participate in the perception of concentration invariance of odorant recognition (Storace and Cohen, 2017); thus, the bulb is simultaneously carrying out more than one computation, as is true of other mammalian brain regions and perhaps is the case for all animals with sophisticated nervous systems. However, in contrast with other sensory systems (Van Essen et al., 1992), the very first processing stage in the olfactory system has an output that may directly represent perceptions.

Bamboo and wood fibers are important raw materials for pulp and papermaking, as well as fiber-reinforced composites. The mechanical properties of single fibers and the cell walls of moso bamboo (Phyllostachys heterocycla), Masson pine (Pinus massoniana), and Chinese fir (Cunninghamia lanceolata) were tested via single fiber tensile test and nanoindentation; their fracture characteristics were also compared. The single fibers and cell walls of moso bamboo had superior mechanical properties compared with those of Masson pine and Chinese fir. The bamboo fibers exhibited high strength, high elasticity, and superior ductility. The results indicated that the differences between the mechanical properties of the fiber cells and cell walls of moso bamboo and those of wood were largely dependent upon cell shape and structure.

The specific energy absorption of a thin-walled tube can be improved by filler. This study examined the potential use of a cheaper biomass filler, paper scraps, to enhance the energy absorption characteristics of the structure while reducing its cost, compared to that with a traditional filler such as foam material. Quasi-static crushing tests and finite element simulations were performed by using the explicit non-linear finite element software LS-DYNA to determine the improvements to the mean crushing force and specific energy absorption of the steel tube when filled with different densities of paper scraps. The mean crushing force and specific energy absorption of the empty tube, the paper scraps, and thin-walled tube filled with paper scraps were determined, and corresponding numerical simulations were performed. The simulation and test results showed that the impact performance of tube filled with paper scraps was greatly improved when paper scraps density was 0.35 g/cm3. By optimizing paper scraps filling structure, a new structure that could further enhance the specific energy absorption was obtained. The optimal scheme could increase the specific energy absorption of Q345 steel tube by 11.35%.

This study investigated the effects of adding ammonium dihydrogen phosphate (ADP) on the physical and chemical changes of a water-soluble extract of the inner part of oil palm trunk (OPT) to clarify the bonding mechanism of the binderless particleboard. The extract’s effect on ADP-added binderless particleboard was also investigated. OPT particles were treated by hot water at 60 °C for 6 h. Water-soluble extract and treated OPT particles were obtained. ADP was added to the water-soluble extract at 0, 10, and 40 wt%, and the mixtures were heated at 180 °C for 10 min. Furthermore, binderless particleboards using the treated particles were manufactured with similar condition. The 10 wt% ADP mixture changed the water-soluble extract to an insoluble substance, which was twice that of with 0 wt.% ADP addition. Infrared spectroscopy revealed peaks of furan and carbonyl in the insoluble substance. This indicated that the free sugar content in the water-soluble extract would change to furan compounds. Thermal analysis revealed that the resulting insoluble substance had good thermal stability, suggesting a high-molecular-weight substance. The insoluble substance would contribute to bonding of the binderless particleboards. In particular, a significant contribution to the water resistance was observed.

Climate change has a huge challenge to 2050. Some renewable energies can be installed to reduce CO2 production. Unfortunately, the photovoltaic systems, wind energy, and ocean energy devices do not have direct thermal applications. These systems are useful for people’s electricity consumption. Absorption heat pumps (AHP) are thermal devices for increasing the temperature level from an energy source at medium temperature level, such as plane solar collectors, to another energy sink. The main problem with design, power calculations and device construction is a lack of education about this technology, which is more complex than compression heat pumps but with 90 % less electric energy consumption that would be supplied by photovoltaic cells. This paper shows an approximation for future engineers designing several absorption heat pumps to avoid global warming beyond the Paris Agreement. Future engineers should be encouraged to analyze this technology with this first and basic approach.
GENETIC MODEL OF MUD VOLCANISM OF THE KERCH PENINSULA (SCIENTIFIC AND APPLIED ASPECTS)

Published: August 2021

The work is devoted to the results of many years of research and observations of mud volcanoes on the Kerch Peninsula. It aims to reveal the most important factors and aspects related to their origin, activity and impact on the geological history of the region. About 50 fossil and modern mud volcanoes have been defined on the Kerch Peninsula and the adjacent part of the water area. Their activity is consistent with the phases of activation of the alpine tectogenesis of the Crimean-Caucasian segment and is intermittent and impulsive. In the geological history of the peninsula, four main bursts of mud volcanic activity are clearly recorded: in the Upper Maikop, Chokrak-Karagan, Sarmatian and Cimmerian. Its greatest activity is manifested in the late Miocene and early Pliocene. Favorable factors for the development of mud volcanoes within the peninsula are the presence of a thick layer of plastic clays enriched in water and gas fluids, the widespread development of brachyanticlinal folds in the Neogene structural surface and a network of deep faults and fractures. The activity of mud volcanoes is associated with the formation of specific compensation structures – depressed synclines, which have become widespread on the Kerch Peninsula. The latter, depending on the paleogeographic conditions (sea, land) and the structural position of volcanoes in the anticlines, have acquired different specifics of structure and filling. Some depressed synclines are associated with iron ore deposits, which differ from typical iron ores of the mulde type by significant capacity, structural and textural features and material composition. Components of hydrothermal and exogenous origin have been defined in the products of mud volcanism: mud gases, mud waters, mud breccias, which indicates the genetic connection of this phenomenon with deep and near-surface processes. In addition, liquid, solid and gaseous hydrocarbons are often detected in volcanic eruptions. The latter are a criterion for searching for oil and gas at depth. Mud volcanoes of the Kerch Peninsula are a unique testing ground for monitoring the processes of modern mineral formation, the dynamics of deep processes and seismic activity in the region.

ABSTRACT Objective: to analyze the correlation between stress, overload and quality of life of informal caregivers of children with and without orofacial cleft and dysphagia. Method: a cross-sectional, case-control study carried out in a public and tertiary hospital, located in the inland of São Paulo, Brazil, which encompassed two groups: case and comparative. The case group consisted of 30 informal caregivers of children with orofacial cleft and dysphagia, using a feeding tube, while the comparative group consisted of 30 informal caregivers of children without orofacial cleft, fed orally. For data collection, the Bourden Interview Scale, Inventory of Stress Symptoms for Adults and the World Health Organization Quality of Life Bref were used. For statistical analysis, the following tests were used: chi-square, Student's t, Mann-Whitney and Pearson's correlation, all with a 5% significance level. Analysis of the linear correlation forces was also used. Results: in the case group, stress presented a moderate correlation with the overall quality of life (r=-0.41; p=0.025) and satisfaction with health (r=-0.42; p=0.021). Also in the case group, referring to quality of life, the Physical and Psychological domains presented a strong correlation with overload (r=-0.54, p=0.002; r=-0.55, p=0.002, respectively). In the comparative group, no correlations were identified. Conclusion: among the informal caregivers of children with orofacial cleft and dysphagia, there was a correlation between stress and the perception of global quality of life and satisfaction with health, as well as between overload and quality of life, in the physical and psychological dimensions.
