STUDY ON THE RAPE POD SHATTER RESISTANCE SUITABLE FOR LOW-LOSS HARVESTING OF HARVESTER REEL
Authors: Qing Yiren , Li Yaoming , Xu Lizhang , Ma Zheng
Published: May 2021

During the mechanical harvesting of rapeseed, the impact of the rotating reel tine on rape can easily cause the pods to burst and seeds drop. However, the specific size of the pod shatter resistance suitable for mechanical harvesting is unsure. In this paper the impact force on the rape was analysed through the measurement and wireless transmission of stress change of the tine. A two-degree-of-freedom (2-DOF) collision tester of pod resistance for field testing was used. The results of the shatter resistance index (SRI) under 2-DOF method and the cracking force under ripping method were compared. According to the results of SRI, cracking force and tine impact force, the expected field SRI was determined. The results show that the tine impact forces at the low reel speed of 18 revs min-1 was 1.76 N. The 2-DOF method results are reliable and the SRI is significantly correlated with the cracking force. The SRI should be over 0.576 to be greater than the impact force under the low reel speed, however, only 14.8% of the tested varieties could satisfy. It indicates the resistance of the commercial varieties is generally poor and need to strengthen.

"We discuss the possible mechanism of genesis of disordered regions in cellulose microfibrils. In our work, we show
that obstacles stopping the growth of nanofibrils and the further deformation of nanofibrils may be the reasons for
disorder. In this case, the initial prismatic shape of nanofibrils becomes corrugated and regions, where cellulose chains
lose their initial straight configuration, appear in it. If a pack of thus deformed nanofibrils form a microfibril, then it
contains disordered regions of two types. The first one consists in boundary layers, which separate nanofibrils from
each other. The second type represents amorphous regions located inside each nanofibril. In this discussion, we use the
linear theory of elasticity. With its help, we estimated longitudinal dimensions of cellulose crystallites and then
compared them with values of such sizes calculated based on experimental data. The experimentally obtained values
turned out to be, to a certain extent, greater than the theoretically estimated ones."

"In this research, bacterial cellulose (BC) was produced from Komagataeibacter xylinus S4 isolated from home-made wine vinegar (Denizli-Çal) and characterized through morphological and biochemical analyses. K. xylinus was identified by 16S rDNA sequence analysis. The wet (51.8-52.8 g) and dry (0.43-0.735 g) weights of the produced BC were measured. The morphology of cellulose pellicles was examined by scanning electron microscopy (SEM) and a dense nanofiber network was observed. TGA analysis showed that the weight loss in the dehydration step in the BC samples occurred between 50 °C and 150 °C, while the decomposition step took place between 215 °C and 228 °C. Also, the cytotoxic effect, moisture content, water retention capacity and swelling behavior of BC were evaluated. In vitro assays demonstrated that BC had no significant cytotoxic effect. It was found that BC had antibacterial and antibiofilm potential (antibacterial effect>antibiofilm effect). All the results clearly showed that the produced BC can be considered as a safe material for different purposes, such as wound dressings."

"Many researchers have studied ways to convert various agricultural by-products into useful eco-friendly polymer
composites due to the demand for sustainable production. Poly(furfuryl) alcohol (PFA) seems to be one of the
emerging eco-friendly polymers, particularly when impregnated with cellulose. Cellulose is the most abundant
biopolymer and organic compound on earth, extracted from a variety of materials, such as plants, animals
(tunicates), algae and bacteria. Nanocrystalline cellulose serves as elementary “building blocks”, with properties
such as uniformity and durability, which are critical for second-generation cellulose-based products and their
engineering applications. This review focuses on the latest research on PFA reinforced with cellulose
nanowhiskers. The most commonly used method to prepare composites is in-situ polymerization, which yields
cellulose PFA composites with a significant increase in thermal stability and mechanical properties. The
viscoelastic properties of cellulose PFA nanocomposites were also proven to enhance, in terms of storage modulus
and flexural strength, with a reduction in the energy loss, evident by the intensity of the tan peaks. Critical
milestones that still need to be achieved by researchers are clearly outlined in the review. Also, solid
recommendations in terms of interrupting polymer composites markets using PFA composites are made."

Authors: MOTTA NEVES ROBERTA , DALL AGNOL LUCAS , ORNAGHI HEITOR LUIZ
Published: May 2021

"The amount of residues generated from different sources is highly variable as a function of many factors, including the
soil, climatic and plant characteristics, as well as the location of the plantation site. In this context, post-consumed
yerba mate and coffee are gaining special attention due to their enormous potential to be used for different applications:
as reinforcement in polymeric matrices, fertilizers, and in combustion production. Yerba mate is common in the South
region of Brazil and it is traditionally consumed by locals. Coffee grounds are also widely available as coffee is
consumed around the world. Hence, the present study has as its main objective to study the chemical composition,
thermal stability and morphology of post-consumed yerba mate and coffee. Also, the TG curve based on the chemical
composition of both residues has been evaluated using a predictive kinetic model. The main results indicate an
excellent TG simulated curve based on chemical composition. The results can help to rapidly estimate the thermal
degradation behavior of materials for their further applications."

Published: May 2021

"Photo-catalytic degradation of organic dyes in aquatic environments under visible light irradiation affords an efficient
and economic technique for environmental remediation. TEMPO-oxidized cellulose nanofibers/zinc oxide
nanocomposite (TEMPO-CNF/ZnO) was prepared through oxidation of cellulose pulp, followed by zinc oxide
precipitation in the presence of oxidized fibers. TEMPO-CNF/ZnO was characterized by different techniques. The
degradation rate of methylene blue (MB) by TEMPO-CNF/ZnO was gradually increased with increasing pH and the
degradation reached 86% within 340 minutes at pH 7. The kinetic study showed that the pseudo-first-order kinetic best
fitted the photo-catalytic process. A mechanism was proposed for the degradation of MB using TEMPO-CNF/ZnO
under visible light irradiation. TEMPO-CNF/ZnO showed high antibacterial activity against S. aureus and E. coli.
Thus, the TEMPO-CNF/ZnO nanocomposite has been demonstrated to be an effective photo-catalytic material for
degrading MB under visible light irradiation."
CITRIC ACID CROSSLINKED NANOFIBRILLATED CELLULOSE FROM BANANA (MUSA ACUMINATA X BALBISIANA) PSEUDOSTEM FOR ADSORPTION OF Pb2+ AND Cu2+ IN AQUEOUS SOLUTIONS
Authors: LACARAN JARED VINCENT T. , NARCEDA RONALD JEFFERSON , BILO JOSANELLE ANGELA V. , LEAÑO JR JULIUS L.
Published: May 2021

"Nanofibrillated cellulose was isolated from banana pseudostem, a common agricultural waste, using acid hydrolysis
and ultrasound irradiation and was thermochemically crosslinked with citric acid and used for the adsorption of Pb2+
and Cu2+ ions in an aqueous solution. The synthesized nanofibrillated cellulose was characterized using scanning
electron microscopy (SEM), energy dispersive X-ray (EDX), Fourier-transform infrared spectroscopy (FTIR), and the
analysis of the point of zero charges (PZC). The SEM data showed that nanofibrillated cellulose has a width of around
69 nm and the EDX spectra depicted the successful removal of inorganic constituents. The linkage of citric acid to
cellulose was confirmed by FTIR and the analysis of the PZC revealed that citric acid modification imparted negatively
charged carboxyl groups to the cellulose surface. The optimization of the solution pH and adsorbent dosage showed
that 99% of Pb2+ and Cu2+ ions were removed under optimum conditions of pH 5 and 2.5 g/L of adsorbent, with high
recyclability and following the Freundlich isotherm model. In addition, it was found that the adsorption process is
exothermic, reversible, and driven by physisorption. The maximum adsorption capacity was found to be 205.42 mg/g
for Pb2+ and 56.04 mg/g for Cu2+, which makes CA-NFC comparable to existing citric acid modified agricultural
wastes."

"Lignocellulose-rich spent mushroom compost (SMC) has been found to contain various functional groups that can be
used for biosorption. Effluent samples collected from common effluent treatment plants (CETPs), i.e. Ludhiana
Electroplaters Association (L-CETP) and Punjab Small Industries and Export Corporation (PSIEC) Leather Complex,
Jalandhar (J-CETP), were analyzed for different waste water quality parameters, such as Dissolved Oxygen (DO),
Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and heavy metal profile. Chromium was the
dominant heavy metal in both samples, with a concentration of 226.62 ppm in L-CETP and 1.83 ppm in J-CETP. Spent
compost of different cultivated mushrooms was analysed for its use in chromium biosorption by varying
physicochemical parameters. Maximum removal of Cr was obtained at an initial metal concentration (Ci) of 50 mg/L,
pH 6 and temperature of 25 °C. Experimental results were well fitted to the Langmuir and Freundlich isotherms.
Fourier transform infrared (FT-IR) spectra showed a shift in peaks, indicating the functional groups involved in
biosorption of chromium."
Noncontact manipulation of particles in air by switching pulse drive of ultrasonic speakers arrayed on a semicylinder

Published: May 2021

Noncontact micromanipulation techniques are necessary for micromachine technology, biotechnology, materials processing, and so on. By using a bolted Langevin transducer and a reflector, one can trap small objects in air at nodes of sound pressure in a standing wave field, but such a technique requires high-voltage drive and careful tuning to achieve resonance. In this study, a large number of small ultrasonic speakers were placed on the inner surface of a semicylinder to form a strong sound field in the focus line. We showed that the pressure node can be moved, and thus the small object, along the focus line simply by switching the driving ultrasonic speakers without using complex electronics. We also showed that the object can be trapped and manipulated even at a duty ratio of 50% in tone burst waves. The above results are discussed by showing the experimental and calculated sound pressure distributions.

Lifecycle Optimization of Smart Contract for Different Scenarios in 6G Network
Authors: Su Hong , Guo Bing , Suo Xinhua
Published: May 2021

Smart contract-based methods are used to implement the blockchain applications. While smart contracts have separate pre-deployed steps, which are suitable for applications that are deployed once and invoked many times. However, there are smart contracts that are used only one time (the disposable smart contract) or few times. Pre-deployment requires an additional step and additional transactions, which bring burdens (such as longer waiting time and more transaction fees) to users. In this paper, we propose a new Lifecycle model of smart contracts, which allows combining the pre-deployment with function invocations. This facilitates the usage of the disposable smart contract, as users are only required to send one transaction to perform both the pre-deployment and the function invocation. Together with the smart contract separation, it also allows participants to customize their special smart contracts at the request time. At last, we verify the proposed model and it shows the potential to save additional burden and to facilitate the usage of the smart contract.

Published: May 2021

O artigo analisa as políticas curriculares no Brasil no contexto de produção da Base Nacional Comum Curricular (BNCC) e suas implicações sobre os componentes disciplinares considerados não obrigatórios e não prioritários, após a promulgação da Lei da Reforma do Ensino Médio de 2017. Tomando por base a disciplina Sociologia, foi possível constatar descontinuidades no processo de elaboração do documento oficial e alterações nos sentidos dados à etapa do Ensino Médio e ao ensino de Sociologia a partir da ascensão de segmentos políticos que defendem uma agenda liberal. A constatação se deu a partir da análise crítica, ora tomando como referência a forma, ora os conteúdos, das diretrizes apresentadas nas três versões curriculares da BNCC, dos pareceres de especialistas e das conexões com as dimensões política, econômica e educacional.

Este estudo se debruça sobre os downshifters -  indivíduos que fazem a opção por desacelerar seus ritmos de vida, buscando equilíbrio entre trabalho e lazer e estilos de vida mais frugais de forma a minimizar os efeitos das sociedades industriais capitalistas urbanas. Explora um tipo particular de comportamento em um estrato social específico - um grupo social formado por famílias que têm filhos em uma escola Waldorf, em Florianópolis, Brasil. Foi possível perceber que os aspectos formadores de movimento altera não só indivíduos, mas também as famílias inseridas no espaço educacional que se apresenta como resistência ao sistema educacional tradicional. Os Waldorf assumem premissas do downshifting. Sob a ótica da contracultura, formam um grupo coeso de classe média que tende a restringir sua rede social àqueles que compartilham o mesmo estilo de vida; suas ações cooperativas fomentam sentimentos de pertencimento e solidariedade que ajudam a legitimar estilos de vida alternativos em uma sociedade consumista.
Babalaze das hienas e a memória coletiva moçambicana
Authors: De Azevedo porto Gustavo , Ferreira Alves Adeir
Published: May 2021

Este artigo traz uma reflexão sobre a poesia do escritor moçambicano José Craveirinha, na obra Babalaze das hienas (2008). Nessa reflexão analisamos o lugar da oralidade e da africanidade na poesia de Craveirinha, que evoca a memória coletiva do seu país, duramente afetado pela guerra civil. O sentimento nacional e o africanismo evocados na poética de Craveirinha não apenas expõem as dores e os horrores que assolaram o seu povo, mas também apontam caminhos de emancipação identitária, política e cultural das opressões colonialistas. Por estas razões é que a escrita de Craveirinha é, em certa medida, um tratamento africano para preservação de sua cultura. Para tal análise será considerado o poder da oralidade africana na construção deste processo catártico, uma vez que o poeta tem como fonte de inspiração para sua escrita as memórias e as vozes da população atingida pela guerra.

Published: May 2021

Este trabalho discute como as narrativas em abismo são construídas nas obras Terra sonâmbula, de Mia Couto, e Meio sol amarelo, de Chimamanda Ngozi Adichie e como os personagens dessas narrativas descrevem suas experiências em tempos de guerra. Especialmente sob a perspectiva dos estudos de Jeanne Marie Gagnebin (2009) acerca da escrita como manutenção de lembrança para as futuras gerações, verifica-se que tais personagens elegem a escrita como forma de elaboração do passado e para organizar sua memória. São, portanto, personagens-autores que, no seu fazer literário, dão voz aos vivos e mortos das guerras, apagando sua própria voz.

Need support, need satisfaction and types of motivation in Physical Education for children aged 8 to 13. Development and preliminary validation of the German SMoPE-instrument
Authors: Kohake Kathrin , Heemsoth Tim
Published: May 2021

More self-determined motivation of young children in physical education (PE) has been shown to improve physical activity through the lifespan. According to Self-Determination Theory, an educational environment that supports the three basic psychological needs of autonomy, competence, and relatedness is expected to facilitate need satisfaction and, therefore, more self-determined types of motivation. However, thus far there are no appropriate instruments to investigate the psychological need support, need satisfaction, and motivation for younger students simultaneously. The present study aims to develop and preliminarily validate the German SMoPE-instrument (Students’ motivation in Physical Education) for the constructs need support, need satisfaction, and types of motivation for 8-13-year-old children in PE. Therefore, after a cognitive lab study, N = 1,011 students from grade 3 to 6 answered a questionnaire with items that based on research in the field of extracurricular sports with regard to the three constructs. The result is a questionnaire of 33 items including three need-support-subscales, three need-satisfaction-subscales and five subscales regarding the types of motivation. Confirmatory factor analyses with acceptable to excellent fit indices for all scales as well as a satisfactory simplex structure concerning the types of motivation support the suitability of the constructs. In addition, multiple regression analyses show positive relationships between the support of competence and both intrinsic and identified motivation. Consistent with theoretical considerations, both relationships were partially mediated by the satisfaction of competence.

Purpose: Failure of anterior cruciate ligament often occurs in young sports personnel hampering their career. Such ACL ruptures are quite prevalent in sports such as soccer during dynamic loading which occurs at more than one rate of loading. In this work, a structural constitutive equation has been used to predict the forces acting on ACL for different rates of loading. Methods: Ligaments with distal femur and proximal tibia were subjected to tensile loading to avoid crushing of tissue ends and slipping at higher rates of strain. Custom designed cylindrical grippers were fabricated to clamp the distal femur and proximal tibial bony sections. To estimate parameters for the model, eighteen fresh cadaveric femur-ACL-tibia complex (FATC) samples were experimented on by pure tensile loading at three orders of rates of strain viz., 0.003, 0.03, and 0.3 s–1. The experimental force-elongation data was used to obtain parameters for De-Vita and Slaughter’s equation. The model was validated with additional tensile experiments. Results: Statistical analysis demonstrated failure stress, Young’s modulus and volumetric strain energy to vary significantly as a function of rate of strain. Midsection failure was observed only in samples tested at 0.03 s–1. Femoral or tibial insertion failure were observed in all other experiments irrespective of rate of strain. Conclusion: Human FATC samples were tensile tested to failure at three rates of strain using custom-designed cylindrical grippers. A structural model was used to model the data for the ACL behaviour in the linear region of loading to predict ligament behaviour during dynamic activities in live subjects.
Joint loads and muscle force distribution during classical and jazz pirouettes
Authors: Błażkiewicz Michalina
Published: May 2021

Purpose: The objective of this study was to analyze the muscle force distribution and lower limb joint loading during two types of pirouettes and check which muscle in which pirouette generates the highest force and which joint is the most loaded. Methods: Skilled dancers (n = 16) performed single-turn pirouettes in jazz and classic styles. Kinematic and kinetic data were collected using the Vicon system and Kistler plates. The joint reaction forces and muscle forces were calculated using a musculoskeletal model in the AnyBody Modeling System. Results: No statistically significant differences were found for the duration of the turn in both pirouettes. The range of motion in all joints of supporting leg in sagittal plane and in hip joint in frontal plane for non-supporting leg were significantly higher in classic pirouette. The ankle joint was the most loaded joint in both pirouettes and its maximal value was significantly higher in classic pirouette. The force generated by ankle plantar flexors muscles was significantly greater in the jazz pirouette in turn phase. For the nonsupport limb, external hip rotators generated significantly greater force when performing the classic pirouette. Conclusions: It seems that early stage dancers may start their lessons with jazz pirouettes, where necessary joint mobility is lesser. They also are supposed to increase muscle strength and body awareness with such proceedings. A better awareness of the mechanical loads on the musculoskeletal system which a dancer performing pirouettes faces should have an impact on the way dance classes are conducted and choreographic elements are sequenced.

Purpose: Atherosclerosis causes plaque to build-up in arteries. Effect of the specific local hemodynamic environment around an atherosclerotic plaque on the thrombosis formation does not remain quite clear but is believed to be crucial. The aim of this study is to uncover the flow effects on plaques formation. Methods: To study the mechanically regulated plaque formation, the flow fields in artery blood vessels with different stenosis rates at various Reynolds numbers were simulated numerically with the two-dimensional axisymmetric models, and the hemodynamic characteristics around the plaque were scaled with stenosis rate and Reynolds number. Results: The results showed that increases of both Reynolds number and stenosis rate facilitated the occurrence of flow separation phenomenon, extended recirculation zone, and upregulated the maximum normalized wall shear stress near the plaque throat section while downregulated the minimal normalized wall shear stress at the front shoulder of plaque, as it should be; in the atherosclerotic plaque leeside of the recirculation zone, an obvious catch bond region of wall shear stress might exist especially under low Reynolds number with stenosis rate smaller than 30%. This catch bond region in the plaque leeside might be responsible for the LBF (low blood flow)-enhanced formation of the atherosclerotic plaque. Conclusions: This work may provide a novel insight into understanding the biomechanical effects behind the formation and damage of atherosclerotic plaques and propose a new strategy for preventing atherosclerotic diseases.

Authors: Łagan Sylwia D. , Liber-Kneć Aneta
Published: May 2021

Purpose: The aim of the study was to investigate the viscoelastic response in the low and high physiological strain with the use of experimental and modeling approach. Methods: Viscoelastic response in the low, transition and high physiologic strain (3, 6 and 9%) with consideration of simulated biological environment (0.9% saline solution, 37 °C) was measured in relaxation tests. Preconditioning of tendons was considered in the testing protocol and the applied range of load was obtained from tensile testing. The quasi-linear viscoelasticity theory was used to fit experimental data to obtain constants (moduli and times of relaxation), which can be used for description of the viscoelastic behavior of tendons. The exponential non-linear elastic representation of the stress response in ramp strain was also estimated. Results: Differences between stress relaxation process can be seen between tendons stretched to the physiological strain range (3%) and exceeding this range (6 and 9%). The strains of 6% and 9% showed a similar stress relaxation trend displaying relatively rapid relaxation for the first 70 seconds, whereas the lowest strain of 3% displayed relatively slow relaxation. Conclusions: Results of the model fitting showed that the quasi-linear viscoelastic model gives the best fit in the range of low physiological strain level.

Purpose: The purpose of this study was to evaluate kinematic variables at 5 running speeds (8 to 12 km/h), for the asymmetry between lower limbs. We also investigated the effects of running speed on the bilateral asymmetry of the lower limb joints kinematic variables among novice runners. Methods: Kinematic (200 Hz) running data were collected bilaterally for 17 healthy male novice runners (age: 23.1 ± 1.3 years, height: 1.77 ± 0.04 m, mass: 72.3 ± 4.57 kg, BMI: 23.1 ± 1.0 kg/m2) running on a treadmill at 5 fixed speeds (8, 9, 10, 11 and 12 km/h) in a randomized order. Symmetry angles (SA) were calculated to quantify gait asymmetry magnitude at each running speed. Results: Overall, SPM analysis using paired t-tests revealed significant joints kinematic differences between the left lower limb and the right lower limb at each running speed. Significant differences between limbs were found for all joint kinematic variables in the ankle and hip, regardless of running speed. As for the knee angle, significant differences between legs were only found during the running speed of 11 km/h. For knee angle velocity, significant differences between legs were found in all running speeds except for 8 km/h. However, there was no noticeable difference in asymmetry values across running speeds. Conclusions: The findings of the current study indicate that gait asymmetry of joint kinematics variables between lower limbs during running is apparent in healthy novice runners. Meanwhile, running speed does not influence lower limb joints kinematic asymmetry among novice runners.

Purpose: The clinical outcomes of total hip arthroplasty are influenced by the correct muscle function that determines good, longterm and proper function of the artificial joint. The aim of the study was to analyze the electromyographic activity of the gluteus medius muscle in patients with hip osteoarthritis and after arthroplasty in various static weight bearing conditions, both on the affected and contralateral side. Methods: The prospective study involved 70 patients qualified for hip replacement. Patients underwent a surface electromyography of the gluteus medius muscle which involved the Trendelenburg test. The normalized results were obtained for both hips, preoperatively and 6 months after arthroplasty. Results: The only muscle activity differences were found at a full load condition of lower limb. In the preoperative assessment, the activity of the gluteus medius muscle was greater on the side qualified for surgery. After arthroplasty and the rehabilitation period, the muscle activity on the operated side decreased and significantly increased on the contralateral side. Detailed analysis of the contralateral side revealed relationship with osteoarthritis. Previous hip arthroplasty of that side resulted in lower muscle activity, similar to fully functional joints. Conclusion: The activity characteristics of the gluteus medius muscle vary depending on the condition of the joint, and the characteristics change as a result of the surgical procedure performed on both the operated and contralateral sides. These dependencies should be taken into account in the rehabilitation process, especially at the side opposite to the operated one.

We give different bounds for the Stanley depth of a monomial ideal I of a polynomial algebra S over a field K. For example we show that the Stanley depth of I is less than or equal to the Stanley depth of any prime ideal associated to S/I. Also we show that the Stanley conjecture holds for I and S/I when the associated prime ideals of S/I are generated by disjoint sets of variables.
