Published: September 2021

Introdução: No setor agrícola o controle de pragas é essencial para garantir que a cultura se desenvolva, pois diversas pragas acometem as culturas, e algumas delas ocasionam perdas significativas, até mesmo a perda total, devido aos danos causados nas plantas a utilização de um manejo sustentável de pragas é fundamental para um melhor controle de pragas, juntamente com outros métodos de controle, ampliando a diversidade de produtos e modos de controle, e garantindo a sustentabilidade do sistema de produção. Objetivos: O objetivo deste trabalho é realizar uma breve revisão de literatura sobre o manejo sustentável de pragas na agricultura, caracterizando e demonstrando a sua importância no sistema de produção agrícola sustentável. Material e métodos: O presente estudo foi realizado com base na revisão de literatura e pesquisas relevantes sobre o manejo sustentável de pragas na agricultura, demonstrando a importância em um sistema de produção sustentável. Resultados: No manejo de pragas sustentável, dois métodos de controle são importantes, o controle biológico e de origem vegetal, que são inseticidas biológicos e a base de extratos vegetais, e são definidos como meios alternativos de controle de pragas, e com resultados de controle bons, com efeitos similares aos dos produtos químico. O controle biológico é um método de insetos que usa inimigos naturais das pragas, com a ação de parasitoides, predadores e patógenos na manutenção da densidade de outro organismo a um nível mais baixo do que ocorreria normalmente. O controle com produtos de origem vegetal, ocorre o uso de produtos com base em extratos vegetais derivados de plantas, que são inseticidas orgânicos, que apresentam efeitos toxicológicos para uma determinada gama de insetos. A utilização de inseticidas biológicos e com base em extratos vegetais na agricultura é muito importante para futuros cultivos, devido aos diversos benefícios proporcionados, mantendo a sustentabilidade do sistema de produção adotado, em relação à conservação dos recursos naturais e o aumento da biodiversidade nos diversos sistemas de produção.

Authors: Silva Josineide Ribeiro da , Dolci Luciana Netto , Santos Aline Alves Dos
Published: September 2021

Introdução: A pandemia agravou ainda mais os problemas socioambientais, políticos e econômicos no país. Enquanto pessoas morriam negligenciadas pelo poder público, nós, professoras e a nossa maneira de fazer arte, fazíamos a nossa parte, resgatando vidas da depressão, da ansiedade, da solidão, que também estavam matando. A estética fez com que as pessoas sorrissem mesmo amedrontadas, acreditassem mesmo estando sufocadas pelo terror, que voltassem a sonhar com um futuro melhor, mesmo quando tudo apontava para o obscuro. Objetivos: Desse modo, o presente trabalho tem por objetivo apresentar a poesia de cordel potencializada pela Educação Estético-Ambiental, como forma de humanização na atual conjuntura mundial, com a necessidade prioritária de manter o distanciamento social, aumentando as chances de depressão e solidão nas pessoas, tornando-as reféns dentro de suas próprias casas, sufocadas e sem esperança, beirando o desespero. Material e Métodos: Acreditamos que é necessário pensar coletivamente sobre quais meios podemos utilizar para conscientizar as pessoas sobre tudo o que está acontecendo no planeta, e que essa pandemia é uma das consequências de nossas atitudes impensadas. Nesse caso, usamos como método a Educação Estético-Ambiental e o Cordel para chegar às casas das pessoas por meio das mídias sociais, dialogando e versando sobre o futuro do planeta e, consequentemente, o nosso; sobre o valor das coisas e das pessoas; sobre esperança e a vontade de novamente abraçar. Resultados: Através da Educação Estético-Ambiental, trabalhada por meio da poesia de cordel, nos valemos da nossa arte para conscientizar, humanizar, acalmar e amorosamente, fazer renascer a esperança de um mundo melhor, harmônico e humanizado. Nos vestimos de nós mesmas e fomos para as mídias sociais dialogar sobre uma Educação que humaniza e transforma, a Estético-Ambiental, utilizando para esse movimento poesias de cordéis. A medida em que o cordel conscientizava, também fazia renascer a esperança de um futuro próspero. Conclusão: Dessa maneira, concluímos que a Educação Estético-Ambiental e a poesia de cordel, fizeram com que os corações aflitos daqueles que nos acompanharam nas mídias se acalmassem, fazendo também com que se conscientizassem da nossa responsabilidade socioambiental, enxergando com isso um novo alvorecer que virá logo depois da tempestade.

Articulation disorder is referred as difficulty occurs in the pronunciation of specific speech sounds. An irregular coordination of the movement of tongue, lips, palate, jaw, respiratory system, vocal tract, height of the larynx, air flow through nasal leads to the incorrect production of speech sounds. The objective of this paper is to propose a computational model based on Recurrent Neural Network (RNN) algorithm to categorize the phonological patterns of Tamil speech articulation disorder signals into four predefined groups, namely, substitution, omission, distortion and addition. The methodology of the proposed work is described as follows. (1) List of articulation disorder test words suggested by Speech Language Pathologists (SLPs) is selected for this experimental study. (2) Real time speech signals that comprise of Tamil vowels (Uyir eluthukkal) and consonants (Meiyeluthukkal) are collected from people with articulation disorder. (3) Acoustic noise and weak signals are eliminated by applying Low pass filter to acquire the filtered speech signal. (4) Mel-Frequency Cepstral Coefficients (MFCCs) technique is implemented to extract the prominent features from denoised signals. (5) Principal Component Analysis (PCA) method is employed to choose fine-tune feature subset. (6) The refined features are employed to calibrate RNN model for classification. Results show that RNN model achieves 90.25% classification accuracy when compared to other artificial neural network algorithms.
Grid-Based Object Tracking
Authors: Steyer Sascha
Published: September 2021

Mobile robots require an accurate environment perception to plan intelligent maneuvers and avoid collisions. This thesis presents a novel multi sensor environment estimation strategy that fully combines tracking moving objects and mapping the static environment. The basic idea is to fuse and accumulate measurement data by a dynamic occupancy grid model, whereas moving objects are extracted subsequently based on that generic low-level grid representation. Overall, this work results in a robust and consistent estimation of arbitrary objects and obstacles, which is demonstrated in the context of autonomous driving in complex unstructured environments.

An Integrated Approach for Traffic Scene Understanding from Monocular Cameras
Authors: Oeljeklaus Malte
Published: September 2021

This thesis investigates methods for traffic scene perception with monocular cameras for a basic environment model in the context of automated vehicles. The developed approach is designed with special attention to the computational limitations present in practical systems. For this purpose, three different scene representations are investigated. These consist of the prevalent road topology as the global scene context, the drivable road area and the detection and spatial reconstruction of other road users. An approach is developed that allows for the simultaneous perception of all environment representations based on a multi-task convolutional neural network. The obtained results demonstrate the efficiency of the multi-task approach. In particular, the effects of shareable image features for the perception of the individual scene representations were found to improve the computational performance.

Optimization of the warm up process of the compression moulds for the tyre manufacturing industry
Authors:   , Tshimbiluni Happy Christian
Published: September 2021

Pneumatic tyres are of major importance in the modern life. It is estimated that over one billion tyres are manufactured worldwide annually. The manufacturing process is rather power consuming one, mainly to a curing operation taking place in a press dome. The tyre compression mould warm up process is a powerful heat transfer technique. Saturated steam is fed into a press dome to directly transfer heat energy into the prismatic container through convection and conduction heat transfer. This dissertation concerns the work done at Apollo-Dunlop tyres, the tyre compression mould warm up process was optimised to reduce the high energy cost. A heat transfer numerical analysis was carried out to investigate the steam quantity required to warm up the tyre compression mould from an ambient temperature ( ) to operational temperature ( ). Thereafter, an experimental work was performed to investigate the actual duration required to warm up the tyre compression mould to the operational temperature. This was achieved by establishing a temperature profile of the tyre compression mould during the warm up session. The numerical analysis and the experimental results were correlated to create a new warm up process with reduced steam consumption and warm up duration. The new warm up process was tested and the results are furnished in this study (see Appendix B for the performance results sheet). Apollo-Dunlop tyres (Pty) Ltd reduced a five hour tyre compression mould warm up process to a three hour process. The implementation of the proposed reduced warm up process occurred after the research work in this paper was presented to Apollo-Dunlop tyres (Pty) Ltd board members. This work was acknowledged by the company management and a new technological process has been implemented (Appendix A for the relevant documents, note: the specifications sheet show the warm-up duration as four hours, but the actual operational warm up duration is five hours). A cost saving analysis on energy usage was carried out to indicate that Apollo–Dunlop tyres will currently save approximately around about 0.64 million per year after implementing this study.
Evaluating the feasibility of converting crude tall oil and tall oil fatty acids into biofuel
Authors:   , Ngcobo Nkosinathi Cedrick
Published: September 2021

The main objective of this study was to evaluate the feasibility of conversion of crude tall oil and tall oil fatty acids into biodiesel. During the Kraft pulping process, Crude Tall Oil originates as tall oil soap, which is separated from recovered black liquor. The soap is then converted to Crude Tall Oil by acidulation with sulphuric acid. The Crude Tall Oil is then fractionated by distillation to produce tall oil fatty acids (TOFA), rosin and pitch. There were a number of conversional methods that were considered but proved to be inappropriate. A base-catalyzed method was inappropriate with due to the high free fatty acid content on the feedstock, and the acid-base catalyzed method was inappropriate due to the long reaction times and large excess of methanol required. An enzyme based conversion method was also found to be inappropriate because of the high price attached to the purchasing of the enzymes and the stability of the enzyme. A procedure of choice was the supercritical methanol treatment, due to the fact that it requires no separate catalyst. A procedure was developed for both the feedstocks (i.e. crude tall oil and tall oil fatty acids) using the supercritical methanol treatment. In supercritical methanol treatment, feedstock and methanol were charged to a reactor and were subjected to temperatures and pressures beyond the critical point of methanol (Tc = 240 °C, Pc = 35 bar). The maximum biodiesel yield obtained from Crude tall oil was 66% and was 81% for the tall oil fatty acids that was produced in a single stage process. The temperature and methanol to feedstock ratio effects was also found to yield a maximum biodiesel yield at 325°C and 40:1 respectively. A 20 minutes reaction time was found to be appropriate for the maximum yield of biodiesel. The final biodiesel produced was also evaluated against a commercial biodiesel product and its parameters measured. The biodiesel resulting from the tall oil fatty acid yielded parameters that were acceptable according to ASTM D6751 specifications for biodiesel. The biodiesel produced from the crude tall oil did not meet the ASTM D6751 specification, and this was mostly attributed to the presence of unsaponifiables which hindered the conversion of oil into biodiesel.
The effectivness of using a non-platinum material combination for the catalyst layer of a proton exchange membrane fuel cell
Authors:   , Reddy Dwayne Jensen
Published: September 2021

The effectiveness of using a low cost non - platinum (Pt) material for the catalyst layer of a polymer electrolyte fuel cell (PEMFC) was investigated. A test cell and station was developed. Two commercial Pt loaded membrane electrode assemblies (MEA) and one custom MEA were purchased from the Fuelcelletc store. Hydrogen and oxygen were applied to either side of the custom MEA which resulted in an additional sample tested. An aluminium flow field plate with a hole type design was manufactured for the reactants to reach the reaction sites. End plates made from perspex where used to enclose the MEA, flow field plates, and also to provide reactant inlet and outlet connection points. The developed test station consisted of hydrogen and oxygen sources, pressure regulators, mass flow controllers, heating plate, and humidification units. A number of experimental tests were carried out to determine the performance of the test cells. These tests monitored the performance of the test cell under no-load and loaded conditions. The tests were done at 25 °C and 35 °C at a pressure of 0.5 bar and varying hydrogen and oxygen volume flow rates. The no-load test showed that the MEA’s performed best at high reactant flow rates of 95 ml/min for hydrogen and 38 ml/min for oxygen. MEA 1, 2, 3, and 4 achieved an open circuit voltage (OVC) of 0.936, 0.855, 0.486 and 0.34 V respectively. The maximum current density achieved for the MEAs were 0.3816, 0.284, 15x10-6, and 50x10-6 A/cm2. Under loaded conditions the maximum power densities achieved at 25 °C for MEA’s 1, 2, 3, and 4 were 0.05, 0.038, 2.3x10-6, 1.99x10-6 W/cm2 respectively. Increasing the temperature by 10°C for MEA 1, 2, 3, 4 resulted in a 16.6, 22.1, 1.79, 10.47 % increase in the maximum power density. It was found that increasing platinum loading, flow rates, and temperature improved the fuel cell performance. It was also found that the catalytic, stability and adsorption characteristics of silver did not improve when combining it with iridium (Ir) and ruthenium oxide (RuOx) which resulted in low current generation. The low maximum power density thus achieved at a reduced cost is not feasible. Thus further investigation into improving the catalytic requirements of non Pt based catalyst material combinations is required to achieve results comparable to that of a Pt based PEMFC.

Abstract

The Western world, communication technology and mass media, have a big hand in building and establishing the moral principles of society. Internet media in particular, have a major role in introducing new norms of society. For the Islamic Ummah it is necessary to strengthen the missionary motivation which takes up so much time and attention of the majority Muslim community. Even now the technological means have been dubbed by the people of various terms for example, as a corona screen, a magic box, a window to the world and so on. The rapid introduction of new norms was made possible because the media moved with the principle of freedom of expression without preaching motivation, so that these principles were often used as a pretext for pursuing worldly interests. Unfortunately, many developing countries, including those claiming to be Muslim countries, follow this trend. As a result, Muslims around the world have been trapped in a foreign conceptual framework, which resulted in a media invasion of their value system, ethical perceptions, moral standards, sociocultural views, and even their religious beliefs. Therefore, Islam needs to set a da'wah strategy in all aspects of life through communication systems, especially electronic media that affect many people. This should not be ignored, and must be directed in accordance with Islamic perinsif which covers all aspects of life through the da'wah strategy. Technological development cannot be dammed. The role of Muslim communicators must defend the truth so that justice remains upheld. Justice cannot possibly be upheld without safeguarding the truth and this is the main task for the Islamic Ummah to carry out scientific charity including one of which is the application user in the mass media.

FORMACIÓN DOCENTE EN LA UPEL-IPM, UNA MIRADA CRÍTICA
Authors: Mercedes Estrada José , Bennasar-García Miguel Israel
Published: September 2021

El presente trabajo aborda la Formación docente en la Universidad Pedagógica Experimental Libertador-Instituto Pedagógico de Maturín (UPEL-IPM). La investigación fue auxiliada por la etnografía, para justificar la escogencia de los informantes clave, que en este caso en total fueron siete (7), que cursaron la asignatura Fase Ida del décimo semestre y cuya práctica fue realizada en Liceo Bolivariano “Victoria Ramírez Molinos, del Estado Monagas, Venezuela. En esta investigación se consideró a la formación docente en la UPEL-IPM como una construcción social, debido a que la misma es el resultado de un complejo proceso dialógico de construcciones colectivas generadas por medio de los discursos vivos producidos por los informantes. Por supuesto, estas construcciones sociales provienen de un conjunto de acciones reales, simbólicas e imaginarias de los informantes. Dentro de las conclusiones más resaltantes se destacan: 1) Se aprecia el énfasis en el deber ser y no en ser; lo cual evidencia una plataforma cultural de su comunidad epistémica, 2) Los testimonios reflejan a una universidad con claridad de misión y visión, en sus fundamentos teóricos; pero en la práctica se presenta una institución descontextualizada, signada por una ruptura de su historicidad, de poca sintonía con la realidad social en la cual está inmersa. La racionalidad con la que algunos elaboran el discurso es una expresión de una lógica de dominación, en la cual se refleja una barrera de comunicación expresada con vocabulario escaso y poca fluidez en terminologías propias del campo educativo.

As estratégias em setores produtivos cimenteiro necessitam de investigações que elevem tangencialmente a busca por mercados e a competitividade das empresas. O cimento é uma das principais commodities mundiais, sensível ao mercado e a preço. Este estudo tem como objetivo de compreender e comparar as estratégias implementadas no passado por empresas atuantes no mercado internacional de cimento. Este artigo utiliza uma metodologia de estudos de caso e revisão bibliográfica e tem como foco apontar proposições que envolvam o processo de internacionalização entre empresas que se internacionalizaram em mercados de tipologia “first movers” e empresas de tipologia “late movers”. Habitualmente, empresas multinacionais que são oriundas de países desenvolvidos iniciaram os seus processos de internacionalização antes das empresas de países em desenvolvimento. Estes últimos já possuíam uma melhor infraestrutura e mão de obra mais qualificada, o que não se replicou nos países em desenvolvimento na mesma época. Como resultados desta comparação este artigo contribui para apontar que existem: (1) diferenças no processo de internacionalização entre “first” e “late movers”; (2) Diferenças culturais que influenciam o processo de internacionalização e (3) Oportunidades e vantagens competitivas diferentes nos processos de internacionalização “first mover” ou “late movers”.

The effect of ultra high-diluted drugs on plant-nematode interaction
Authors: Rodiuc Natalia
Published: September 2021

Among plant pathogens, sedentary endoparasitic nematodes are one of the most damaging pests in global agriculture. Within this group, root-knot nematodes (RKN) Meloidogyne spp. is one of the most specialized phytoparasitic nematodes according to the complexity of the induced feeding sites. These phytopathogenic worms are highly resistant due to the large physiological variability, therefore difficult to fight against. The traditional methods of control, such as the crop rotation and the use of resistant varieties by classical selection are not always effective, time consuming and costly. The modern methods including the application of genetically modified crops (GMO), synthetic pesticides and bionematicides could be dangerous for human health and ecologically hazardous (Thomason, 1987; Malatesta et al. 2002a,b, 2008a,b; Spiroux de VendÃ´mois et al., 2010; Seralini et al., 2012). Therefore, alternative routes must be taken in order to obtain plants resistant to nematodes. The ultra high dilutions (HDs) approach is largely in charge to dissect the infective process. HDs method is eco-friendly, low cost and leaves no residue in the environment. The classical phytopathological methods combined with modern microscopy approaches allowed to characterize the effect of different HD drugs on compatible interaction between model plant Arabidopsis thaliana and root-knot nematodes Meloidogyne incognita.
Preliminary study on force-like effects between As45x, water, and wheat seeds performed by means of the droplet evaporation method
Authors: Kokornaczyk Maria Olga , Baumgartner Stephan , Betti Lucietta
Published: September 2021

Background: The droplet evaporation method (DEM) is based on pattern formation in evaporating droplets. It has been shown that the local connected fractal dimension (LCFD; a complexity measure) of crystalline structures grown in evaporating droplets of wheat seed leakages depended upon whether the seeds were treated with an ultra-high dilution (UHD) or water control.1, 2

In homeopathy it is usually assumed, that UHDâ€™s need to come in direct (physical) contact with the organism to be treated to exhibit their action; however, recently, it has been demonstrated on a wheat seed germination model that UHDâ€™s may influence organisms also at a distance, i.e. without any physical contact. 3 In this case the UHD's effectiveness decreases with increasing distance. Here we test whether DEM might serve also as a tool to study such force-like influences.

In a series of three DEM experiments (E1-3) we studied (i) force-like effects occurring between As2O3 45x treatment (As45x) and undiluted, unsuccussed, ultrapure water (W), (ii) As45x and wheat seeds, as also (iii) whether force-like effects may be shielded by means of aluminum foil, commonly applied for such purposes in homeopathic research.

Abstract. Energetic particle precipitation leads to ionization in the Earth's atmosphere, initiating the formation of active chemical species which destroy ozone and have the potential to impact atmospheric composition and dynamics down to the troposphere. We report on one exceptionally strong high-energy electron precipitation event detected by balloon measurements in middle latitudes on 14 December 2009 with ionization rates locally comparable to strong solar proton events. This electron precipitation was likely caused by wave-particle interactions in the slot region between the inner and outer radiation belts, connected with still not well understood natural phenomena in the magnetosphere. Satellite observations of odd nitrogen and nitric acid are consistent with wide-spread electron precipitation into magnetic midlatitudes. Simulations with a 3D chemistry-climate model indicate almost complete destruction of ozone in the upper mesosphere over the region where high-energy electron precipitation occurred. Such an extraordinary type of energetic particle precipitation can have major implications for the atmosphere, and their frequency and strength should be carefully studied.

Abstract. Methane (CH4) emissions from freshwaters to the atmosphere have a profound impact on global atmospheric greenhouse gas (GHG) concentrations. Anthropogenic footprints such as dam construction and reservoir operation significantly changed the fate and transport of CH4 in freshwaters. The type of particulate organic carbon (POC) in reservoirs is a critical factor controlling CH4 production and emissions. However, little is known of how reservoir operation mediates the distribution of POC and regulates CH4 accumulation in cascade hydroelectric reservoirs. Here, spatial and temporal variations in POC and CH4 were explored in the Xiluodu (XLD) and Xiangjiaba (XJB) reservoirs which are deep valley dammed cascade reservoirs located in the main channel of the upper Yangtze River. Based on the δ13C-POC and N / C mole ratios of particulate organic matter, the results of multi-endmember stable isotope mixing models by a Bayesian model show that terrestrial POC and autochthonous POC accounted for approximately 56 ± 19 % and 42 ± 19 % (SD, n = 181) of POC, respectively. CH4 concentrations and δ13C-CH4 in the cascade reservoirs were potentially influenced by CH4 oxidation. Together with other physicochemical parameters and structural equation model, these results suggested that the input of terrestrial POC was dominantly influenced by water level variations and flow regulation due to reservoir operation. The cumulative effect of POC caused by cascade reservoirs was not apparent at a bimonthly scale. Terrestrial POC was more likely to dominate CH4 accumulation in cascade reservoirs under reservoir operation.
Long-term phenological data set of multi-taxonomic groups, agrarian activities, and abiotic parameters from Latvia, northern Europe

Published: September 2021

Abstract. A phenological data set collected by citizen scientists from 1970 to 2018 in
Latvia is presented, comprising almost 47 000 individual observations of
eight taxonomical groups, in addition to agrarian activities and abiotic
parameters, covering in total 159 different phenological phases. These
original data published offline in annual issues of the Nature and History
Calendar (in Latvian, Dabas un vēstures kalendārs) have been digitized, harmonized, and geo-referenced. Overall, the possible use of such data is extensive, as phenological data
are excellent bioindicators for characterizing climate change and can be
used for the elaboration of adaptation strategies in agriculture, forestry,
and environmental monitoring. The data can also be used in
cultural–historical research; for example, the database includes data on
sugar beet and maize, the cultivation of which was imposed on collective
farms during the Soviet period. Thus, such data are not only important in
the Earth sciences but can also be applied to the social sciences. The data significantly complement current knowledge on European phenology,
especially regarding northern regions and the temporal biome. The data here
cover two climate reference periods (1971–2000; 1981–2010), in addition to
more recent years, and are particularly important in monitoring the effects
of climate change. The database can be considered the largest open
phenological data set in the Baltics. The data are freely available to all interested at https://doi.org/10.5281/zenodo.3982086 (Kalvāne et al., 2020).
