Authors: PIDLISNYUK VALENTINA , STEFANOVSKA TATYANA , BARBASH VALERII , ZELENCHUK TATIANA
Published: May 2021

"The main goal of the study was to investigate processing of Miscanthus x giganteus biomass produced in soil contaminated with lead and other trace elements (TEs) into pulp using chemical pulping. The phytoremediation parameters of the plant were measured during two growing seasons, which confirmed that the process can be defined as phytostabilization; the contaminants were mainly concentrated in the roots and practically did not translocate to the stalks and leaves, which permitted the use of the aboveground biomass to process into pulp using the organosolvent cooking. The chemical composition, morphological structure, and microscopic characteristics of various crops’ stalks were investigated and compared with the same parameters received for wood and other non-wood plant materials: rape, flax, hemp, and wheat straw. Indicators of pulp were studied depending on the duration of the organosolvent cooking. After 90 minutes of the cooking process, the peroxide pulp from M. x giganteus had a breaking length of 8300 m, tear resistance of 310 mN, and burst resistance of 220 kPa, testifying the high values of the indicators. Further research should investigate the properties of pulp produced from M. x giganteus biomass grown in soils contaminated with various TEs, as well as the possible translocation of elements to pulp."

Published: May 2021

"In this study, cellulose was extracted and isolated from orange peel (OP) via alkaline treatment, followed by a bleaching process. The orange peel derived cellulose (OPDC) was characterized and compared with microcrystalline cellulose (MCC). FTIR characterization confirmed the absorption peaks of cellulose for both OPDC and MCC. From the DSC analysis, it was found that MCC possessed higher thermal stability than OPDC. In addition, the results of FESEM and particle size analysis revealed the micro-size dimension of OPDC after the pretreatments. The crystallinity index (CrI) of OPDC (80.14%) was found to be significantly higher than that of untreated OP (23.54%). After that, biodegradable blended films with different weight ratio were prepared using OPDC and MCC with polyvinyl alcohol (PVA) by the solution casting method. According to the FTIR spectra, the shift of the characteristic absorption band and the change of the band intensity observed in the spectra of the PVA/OPDC blended films were similar to those of the PVA/MCC blended films. This confirmed the development of new inter- and intramolecular hydrogen bonds and changes in the conformation between PVA and cellulose. The tensile strength and elongation at break of both PVA/OPDC and PVA/MCC blended films decreased when the cellulose content increased in the PVA matrix. However, the elastic modulus of both films was enhanced when the amount of cellulose increased. By comparison, the PVA/OPDC blended film presented higher tensile strength and elastic modulus than the PVA/MCC blended film. Based on the natural weathering tests, the degradability of blended films increased with a rising amount of cellulose after exposure to degradation tests. The biodegradability of blended films was confirmed by the tiny black spots observed on their surface, which reflected the growth of microorganisms. It was further proven by the morphology studies performed on the surface of the films using FESEM."
PREPARATION OF CARBOXYMETHYL CELLULOSE AND POLYVINYL ALCOHOL (CMC/PVA) HYDROGELS USING FREEZE−THAW PROCESSES FOR ADSORPTION OF Zn2+ AND Cu2+
Authors: PAVANDI NEDA , TAGHAVI ELHAM , ANARJAN NAVIDEH
Published: May 2021

"The preparation of carboxymethyl cellulose and polyvinyl alcohol (CMC/PVA) composites is proposed in the present
work. The CMC/PVA hydrogels were prepared using freeze−thaw processes. The effects of freezing time and of the
number of freeze−thaw cycles on the swelling ratio and gel fraction of achieved hydrogels were evaluated using
response surface methodology. The multiple regression analysis suggested second order polynomial equations as
models for predicting changes of the studied hydrogel characteristics by selected process variables, with relatively high
coefficients of determination (R2 > 0.82). The numerical optimization suggested that freezing the polymer solutions for
5 h and repeating the freeze−thaw process for 5 times would give the most desirable hydrogels with highest either
swelling ratio or gel fraction. Remarkably, the ion adsorption studies showed that the adsorption of Cu2+ and Zn2+ ions
by the hydrogels obeys zero order kinetics and the high capability of the produced optimum hydrogels to adsorb
selected ions from synthetic waste was confirmed."
Socioeconomic and phytosanitary diagnosis of fruit farming in Rolim de Moura, RO, Brazil
Authors: Gudin Geovane Souza , Da Silva Dalza Gomes
Published: May 2021

O objetivo deste trabalho foi realizar um levantamento socioeconômico e fitossanitário sobre a produção de frutas na cidade de Rolim de Moura, RO, Brasil. A pesquisa foi feita com pequenos produtores que trabalham com o cultivo comercial de frutas, a quem enviamos 25 questões objetivas e discursivas, e dos quais 20 produtores foram entrevistados. Os resultados mostraram que o mercado de trabalho atrai os filhos dos produtores para a área urbana, o que reduz a força de trabalho para o cultivo de frutas. Além disso, a falta de assistência técnica (50%) estimula a produção em lugares onde os produtores não são alertados quanto ao uso de equipamentos pessoais protetores, quando aplicam pesticidas. Há, ainda, a falta de recursos tecnológicos, uma razão que, acrescentada à a idade dos produtores, contribui para reduzir a qualidade da produção. No entanto, o principal problema enfrentado para a comercialização das frutas é seu baixo preço. A sanidade vegetal está comprometida, pois identificaram-se doenças em todas as culturas, especialmente nas plantações de maracujá, pois o decréscimo da produção causou o abandono dos cultivos, o que levou os produtores a se envolverem com outras fontes de renda, como a produção leiteira, e apenas 25% dos fazendeiros subsistem da fruticultura.
Regression Analysis of Predictions and Forecasts of Cloud Data Centre KPIs Using the Boosted Decision Tree Algorithm
Authors: Gyeera Thomas Weripuo
Published: May 2021

The National Institute of Standards and Technology defines the fundamental characteristics of cloud computing as: on-demand computing, offered via the network, using pooled resources, with rapid elastic scaling and metered charging. The rapid dynamic allocation and release of resources on demand to meet heterogeneous computing needs is particularly challenging for data centres, which process a huge amount of data characterised by its high volume, velocity, variety and veracity (4Vs model). Data centres seek to regulate this by monitoring and adaptation, typically reacting to service failures after the fact. We present a real cloud test bed with the capabilities of proactively monitoring and gathering cloud resource information for making predictions and forecasts. This contrasts with the state-of-the-art reactive monitoring of cloud data centres. We argue that the behavioural patterns and Key Performance Indicators (KPIs) characterizing virtualized servers, networks, and database applications can best be studied and analysed with predictive models. Specifically, we applied the Boosted Decision Tree machine learning algorithm in making future predictions on the KPIs of a cloud server and virtual infrastructure network, yielding an R-Square of 0.9991 at a 0.2 learning rate. This predictive framework is beneficial for making short- and long-term predictions for cloud resources.

Temporal interfaces and metamaterial response enabled by boundaries
Authors: Stefanini Luca , Ramaccia Davide , Bilotti Filiberto , Toscano Alessandro
Published: May 2021

In the last years, temporal metamaterials have been
exploited as a novel platform for conceiving several
electromagnetic and optical devices based on the
anomalous scattering response achieved at a single or
multiple sudden change of their medium properties,
which however is difficult to carry out in a realistic
scenario In this letter we investigate on the possibility to
emulate the scattering response of a temporal
metamaterial without acting on the medium properties,
but on the effective refractive index and wave impedance
perceived by the wave during the propagation within a
guiding structure rather than the actual material, by
acting on its boundaries. The work presents in closed
form the scattering coefficients achieved when the
boundary properties are suddenly modified for inducing
an effective temporal interface. In this framework,
temporally controlled metasurfaces can be used to
implement the proposed concept, giving an easier path
also to the design and realization of novel devices at
microwave and optical frequencies.
Intelligent Reflecting Surface-assisted Free-space Optical Communications
Authors: Jamali Vahid , Ajam Hedieh , Najafi Marzieh , Schmauss Bernhard , Schober Robert , Poor H. Vincent
Published: May 2021

Free-space optical (FSO) systems are able to offer the high data-rate, secure, and cost-efficient communication links required for applications such as wireless front- and backhauling for 5G and 6G communication networks. Despite the substantial advancement of FSO systems over the past decades, the requirement of a line-of-sight connection between transmitter and receiver remains a key limiting factor for their deployment. In this paper, we discuss the potential role of intelligent reflecting surfaces (IRSs) as a solution to relax this requirement. We present an overview of existing optical IRS technologies; compare optical IRSs with radio-frequency IRSs and optical relays; and identify various open problems for future research on IRS-assisted FSO communications.
Interference Identification for Time-Varying Polyhedra
Authors: Bienkowski Adam
Published: May 2021

Identification of when and where moving areas intersect is an important problem in maritime operations and air traffic control. This problem can become particularly complicated when considering large numbers of objects, and when taking into account the curvature of the earth. In this paper, we present an approach to conflict identification as a series of stages where the earlier stages are fast, but may result in a false detection of a conflict. These early stages are used to reduce the number of potential conflict pairs for the later stages, which are slower, but more precise. The stages use R-trees, polygon intersection, linear projection and nonlinear programming. Our approach is generally applicable to objects moving in piece-wise straight lines on a 2D plane, and we present a specific case where the Mercator Projection is used to transform objects moving along rhumb lines on the earth into straight lines to fit in our approach. We present several examples to demonstrate our methods, as well as to quantify the empirical time complexity by using randomly generated areas.

Published: May 2021

The effect of microelement manganese top-dressing on resistance of soft wheat to powdery mildew № pathogen was studied. То study the effect of the element manganese on the development of the pathogen, wheat seedlings were fed with а 0,2% solution of КМn04. Infected plants not fed with the test solution served as control.

Observations on the intensity of germination of conidia of the powdery mildew pathogen on wheat leaves showed that the spomlation of conidia in the variant with feeding with 0,2% КМn04 solution was lower than in the control variant. We found that in the control variant without the use of а КМn04 solution, the colonies of powdery mildew fungus were characterized Ьу abundant spomlation, the formation of а halo was observed. In the experimental variant the growth and reproduction of conidia proceeded more slowly and halos were not noticeaЫe. In this study in the control variant ofthe experiment, the predominance of conidial chains in the colonies ofthe powdery mildew pathogen was noted in comparison with the variant with feeding.

Thus, it was found that feed solution of0,2% КМn04 leads to а decrease in the formation of appressoria and the number of visiЫe colonies of the powdery mildew pathogen on wheat leaves. The presented results confIГm that top-dressing with microelement manganese enhances resistance ofwheat against powdery mildew.

Authors: Lin Chia-Chi
Published: May 2021

Macrophage infiltration has been identified as an independent poor prognostic factor for several cancers. Macrophages also orchestrate various tumor-promoting processes. This observation sparked an interest to therapeutically target these plastic innate immune cells. To date, blockade of colony-stimulating factor 1 (CSF1) or its receptor represents one of the selective approaches to manipulate tumor-associated macrophages. In this review, I discuss the efficacy and safety of various CSF1 receptor tyrosine kinase inhibitors, anti–CSF1 receptor monoclonal antibodies, and anti-CSF1 monoclonal antibodies in clinical development for patients with cancer and highlight potential combination partners, mainly anti–program cell death protein 1 (PD-1) and program cell death protein ligand 1 (PD-L1) antibodies.

Purpose: The goal of this study was to evaluate the biomechanical effects such as sonoporation or permeability, produced by ultrasound- driven microbubbles (UDM) within microvessels with various parameters. Methods: In this study, a bubble-fluid-solid coupling system was established through combination of finite element method. The stress, strain and permeability of the vessel wall were theoretically simulated for different ultrasound frequencies, vessel radius and vessel thickness. Results: the bubble oscillation induces the vessel wall dilation and invagination under a pressure of 0.1 MPa. The stress distribution over the microvessel wall was heterogeneous and the maximum value of the midpoint on the inner vessel wall could reach 0.7 MPa as a frequency ranges from 1 to 3 MHz, and a vessel radius and an initial microbubble radius fall within the range of 3.5–13 μm and 1–4 μm, respectively. With the same conditions, the maximum shear stress was equal to 1.2 kPa and occurred at a distance of ±5 μm from the midpoint of 10 μm and the maximum value of permeability was 3.033 × 10–13. Conclusions: Results of the study revealed a strong dependence of biomechanical effects on the excitation frequency, initial bubble radius, and vessel radius. Numerical simulations could provide insight into understanding the mechanism behind bubble-vessel interactions by UDM, which may explore the potential for further improvements to medical applications.

Purpose: Recently, titanium (Ti) and its alloys have been widely used in dental and surgical implants in the last few decades. However, there is a loosening effect over a long period usage. Therefore, the present study aimed to increase life of an implant by its surface modification. Methods: In present study, sol-gel process has been applied to create tantalum pentoxide (Ta2O5) layer coating on Ti-substrate. In this technique, polyethylene glycol (PEG) plays an important role to form uniform porous coating, which can have potential application in formation of strong bonding to the natural bone. Results: Microstructural, elemental, structural and binding energy results showed that the material with 100% PEG-enhanced sol-gel Ta2O5 with spin coating onto Ti substrate followed by an optimized sintering temperature (500 °C) has better porous structure than that of 5% PEG-enhanced sol-gel Ta2O5 coating, and would be suitable for tissue in-growth properties. Conclusions: Therefore, it was concluded that the present spin coated 100% PEG-enhanced Ta2O5 coating onto Ti, having the most suitable morphology with enhanced roughness, could be noteworthy for potential tissue in-growth and it could provide desired bonding at the interface of Ti-implant coating and host tissues in biomedical applications.

In the present paper we continue the investigation of nonlinear connections started in [16]. The problem of metrizability of the nonlinear connection on the cotangent bundle is studied. Using the dynamical covariant derivative induced by a regular vector field, we find the coefficients of a metric nonlinear connection. For the particular case of a Hamiltonian space we prove that the canonical nonlinear connection is a unique metric and symmetric nonlinear connection.

This paper is concerned with the integral type boundary value problems of the second order singular differential equations with one-dimensional p-Laplacian. Sufficient conditions to guarantee the existence of at least three positive solutions are established. An example is presented to illustrate the main results. The emphasis is put on the one-dimensional p-Laplacian term [ρ(t)Φ(x 0 (t))]0 involved with the function ρ, which makes the solutions un-concave. Furthermore, f, g, h and ρ may be singular at t = 0 or t = 1.

El rendimiento académico (RA) es condicionado por diversos factores, destacándose la autoestima y la calidad de vida relacionada con la salud (CVRS) como factores influyentes. El objetivo de la investigación fue determinar la asociación entre el estado nutricional, la condición física, la autoestima y la CVRS con el RA en adolescentes. En este estudio de corte transversal participaron hombres (n= 219, 15,82±1,37años) y mujeres (n=200, ± 15,23±0,85 años) de entre 14 y 17 años de edad. El índice de masa corporal (IMC) la circunferencia de cintura (CC), la razón cintura estatura (RCE), la condición física, la autoestima, CVRS y el RA fueron evaluados. En la comparación de los niveles de autoestima, CVRS y RA acorde al estado nutricional, los escolares con obesidad tienen menor puntaje CVRS (P=0,001), del mismo modo la autoestima fue menor en los escolares con sobrepeso y obesos en comparación con sus pares normopeso (P=0,013). En relación al RA no existieron diferencias según estado nutricional (P>0,05). El RA presentó relación positiva con la condición física, la autoestima y la CVRS (P<0,05). Los adolescentes con obesidad presentaron menor CVRS que sus pares con sobrepeso y normopeso, además el RA se ve relacionada con la condición física, la autoestima y la CVRS, por tal motivo es importante incorporar estrategias en los establecimientos educacionales que mejoren esta condición y aporten al desarrollo integral de los escolares.
Academic performance (AP) is conditioned by several factors and the self-esteem and health related to quality of life (HRQoL) are influential factors. The objective of the research was to determine the association between the nutritional levels, physical fitness, self-esteem and HRQoL with AP in adolescents. In this cross-sectional study, men (n = 219, 15.82 ± 1.37 years) and women (n = 200, ± 15.23 ± 0.85 years) between 14 and 17 years of age participated. The body mass index (BMI), waist circumference (WC), height waist ratio (WtHR), physical fitness, self-esteem, HRQoL and AP were evaluated. In the comparison of the levels of self-esteem, HRQoL and AP according to the nutritional status, the schoolchildren with obesity have a lower HRQoL (P = 0.001), in the same way the self-esteem was lower in the overweight and obese schoolchildren in comparison with their normal weight peers (P = 0.013). In relation to AP, there were no differences according to nutritional status (P> 0.05). The AP presented a positive relationship with physical condition, self-esteem and HRQoL (P <0.05). The adolescents with obesity had lower HRQoL than their overweight and normal weight peers, in addition AP is related to physical condition, self-esteem and HRQoL, for this reason it is important to incorporate strategies in educational establishments that improve this condition and contribute to the integral development of school children.

El Cuestionario de Conducta de Alimentación de Adultos (AEBQ, por su sigla en inglés derivada de Adult Eating Behavior Questionnaire) es una de las herramientas psicométricas más usadas para evaluar la conducta de alimentación. El objetivo de este estudio fue adaptar y analizar factorialmente la versión en idioma español del AEBQ. El cuestionario adaptado al idioma español se aplicó en un estudio piloto de 50 voluntarias universitarias entre 20 y 30 años de edad. Se utilizó la técnica de análisis factorial para reducir la dimensionalidad de los datos y evaluar preliminarmente su estructura. Se usó la estadística alfa de Cronbach para explorar la consistencia interna del cuestionario adaptado. El análisis factorial reveló una estructura de 8 factores que explican el 82,8 % de la variación de los datos, lo que es concordante con el número de dimensiones de la conducta de alimentación publicada para el AEBQ original. La consistencia interna fue alta, con valores de la estadística α de Cronbach entre 0,77 y 0,91 para las 8 dimensiones consideradas. En conclusión, la versión adaptada al idioma español del AEBQ presenta una razonable concordancia en su estructura de datos con el cuestionario publicado originalmente en inglés, así como una adecuada consistencia interna. Se deben realizar futuros estudios de mayor tamaño muestral que incluyan participantes de diferentes grupos de edad, sexo y estado nutricional.
The Adult Eating Behavior Questionnaire (AEBQ) is one the most used psychometric tool to evaluate eating behavior. The objective of this study was to adapt and analyze the factorial structure of the Spanish version of the AEBQ. The adapted questionnaire was submitted to a non-probabilistic sample of 50 female university students aged 20 - 30 years old. A factorial analysis was used to preliminary assess data structure, while Cronbach's alpha statistic was used to assess internal consistency. Factor analysis revealed an8-factor structure explaining 82,8% of data variation, which is concordant with data structure of the original AEBQ. The internal consistency was high, with Cronbach's α between 0.77 and 0.91 for all eating behavior dimensions. In conclusion, this Spanish version of the AEBQ shows adequate concordance with the factor structure of the originally published AEBQ, as well as high internal consistency. Future studies will evaluate the validity of the questionnaire in different subpopulation groups according to gender, age or nutritional status

Los déficits nutricionales en la mujer deportista causan numerosos problemas de salud, así como un empeoramiento en el rendimiento deportivo, como consecuencia de estas deficiencias nutricionales. El conocimiento de estos déficits y su prevención deben ser un aspecto principal para cualquier responsable deportivo. Establecer la importancia del estudio de los déficits de energía, proteínas, minerales (Fe, Ca y Mg) y vitaminas (Vitamina D, ácido fólico y vitamina B12) que pueden desarrollar las mujeres deportistas y su relación con la prevalencia de la tríada femenina y constatar la importancia del conocimiento por parte de los responsables deportivos de los problemas derivados de los déficits nutricionales. Se realizó una búsqueda bibliográfica de artículos, entre 2013-2020, relevantes para el objetivo de estudio. Se usaron bases de datos científicas como PubMed y Pennutrition, siguiendo los criterios de exclusión e inclusión elegidos para este estudio. 51 artículos fueron encontrados. Los resultados mostraron la prevalencia de energía, Fe, vitamina D y Ca, así como un suficiente aporte proteico, faltan estudios para determinar los niveles de vitamina B12 y ácido fólico. Se observó, además la prevalencia de mujeres que cumplen con uno o varios factores de riesgo para el desarrollo de la tríada de la deportistas femenina. Es imprescindible la prevención o, el tratamiento, de los déficits nutricionales en las mujeres deportistas para asegurar un correcto estado de salud y un rendimiento deportivo óptimo.
