Affection as a movement of desire bound to pedagogical relations
Authors: Hernández-Hernández Fernando
Published: September 2020

In this article I present my journey through the pedagogy of affection, starting from a conjuncture that made me pay attention, in the teaching of Psychology of Art, Contemporary Visualities and Arts-based Research at the Faculty of Fine Arts, to the entanglement between desire and pedagogical relations. From this crossroad, I consider pedagogical relations (inspired by Bernard Charlot, Elizabeth Ellsworth, Alfred Porres and Max van Manen) as part of an encounter between subjects and knowledge that affects the positions of students and teachers and challenges thedualism ‘them and us’. Desire (based on Gilles Deleuze and Jacque Lacan) emergesin pedagogical relations as an agency that needs to leave behind the obsession to reproduce and, mainly, to interpret, diagnose and classify the student. At this crossroad between pedagogical relations and desires, affects appear when an experience of encounter of subjectivities (how we know and narrate ourselves) and knowledge (how we link ourselves to what we know) takes place. To illustrate this entanglement of pedagogical relations, desire and affects, I present two examples connected with my roles of teacher and researcher. The first one links with an Arts- based Research course where teachers and students learn horizontally and differentially. The second one, focusing in a cartography make by a secondary school teacher to give an account of her learning path, is part of a larger research project "How do teachers learn: educational implications and challenges for social change". Both examples contribute to explore the notion of affection as part of a substantial change in the relationships around politics, research, and pedagogy.

Acceder a la gestión de lo simbólico. Un derecho ciudadano
Authors: Remesar Antoni , Vergel Faro Javier
Published: September 2020

Significar el espacio urbano es una de las actividades más relevantes para permitir su conversión en espacio público, en convertir los sitios en lugares. Para ello es imprescindible ampliar el concepto de “accesibilidad” al nivel de la “accesibilidad simbólica” y entenderla como uno de los nuevos derechos urbanos.El artículo desarrolla los conceptos de “simbolismo a priori” y “simbolismo a posteriori” como estrategias de intervención de significación del espacio público. El primero responde a las operaciones habituales desde la administración, el segundo a los procesos populares de apropiación del espacio.Analizando la experiencia de participación creativa – hoy en curso- en el barrio barcelonés del Bon Pastor el artículo plantea la posibilidad de creación de un lugar de encuentro entre los dos tipos de simbolismo, mediante procesos de co-producción del espacio público, específicamente de su co-diseño.
Complex wavefront sensing based on alternative structured phase modulation
Authors: Li Rujia , Cao Liangcai
Published: September 2020

Spatial light modulators (SLMs), which generate varying phase modulation, are widely used in coherent diffraction imaging. Random patterns are uploaded on the SLM to modulate the measured wavefront. However, a random pattern is highly complex and requires a reliable SLM. In addition, the uncorrelated terms generated from the random modulations need to be sufficiently captured using an imaging sensor with a high signal-to-noise ratio (SNR) to avoid stagnation during iterations. We propose an alternative structured phase modulation (ASPM) method. The modulations are composed of orthogonally placed phase bars that introduce uncorrelated modulations. The ASPM modulation can act as the phase grating; in addition, the modulated intensities are concentrated, which can be captured with a high SNR. The complexity of the ASPM patterns is significantly reduced, which is helpful for utilizing the SLM to generate reliable phase modulation.
Asymmetric transmission in bilayer chiral metasurfaces for both linearly and circularly polarized waves
Authors: Ren Yi , Jiang Chun , Tang Bin
Published: September 2020

In this paper, we numerically and theoretically propose an architecture with bilayer chiral metasurfaces which can achieve asymmetric transmission (AT) for both linearly and circularly polarized waves in the near-infrared region. The research results show that the structure can obtain a maximum AT

∼

0.65

and polarization conversion ratio over 80% for linearly polarized waves. In addition, dual-band AT can even be achieved for circularly polarized waves. The electric field distribution and current vector are presented to explain the physical mechanisms of the AT effects. Our research work may have some potential applications in designing optical diode devices, such as asymmetric wave splitters, polarizers, rotators, etc.

Les rapports de la Géographie de l’art sur l’Histoire de l’art brésilien.
Authors: Romeu Cabral Carlos Henrique
Published: September 2020

Cet article cherche à établir des associations entre le domaine de la Géographie de l'art et l'histoire de l'art brésilien, afin de présenter une nouvelle perspective historiographique, basée sur le déplacement et la circulation des individus et des idées entre des territoires culturellement distincts. A travers quelques concepts élaborés par les géographes de l’art Boris Gresillon, Tomas da Costa Kaufmann et Piotr Piotrowiski et les réflexions de l'historienne de l'art Beatrice Joyeux-Prunel sur les avant-gardes artistiques au Brésil, il est possible de penser à la construction d'une histoire de l'art brésilien, structurée essentiellement à partir de l'étude des transferts culturels transatlantiques basés sur la relation des individus avec les dimensions géographiques, sociales, économiques et culturelles de l'espace. Fondé sur la discussion des centres et périphéries artistiques, l'article révèle l'importance et la nécessité d’étudier la production culturelle des périphéries artistiques au Brésil, à travers la géographie de l’art, afin de contribuer à la construction d'une Histoire de l'art brésilienne globale, inclusive et transnational, capable de réviser des récits hégémoniques et des processus d’exclusion.

FEATURES OF PHYSICAL ADAPTATION OF FIRST-YЕAR UNIVERSITY STUDENTS TO AN URBANIZЕD ЕNVIRONMЕNT
Authors: Mishchenko N , Svinar E , Makarov A
Published: September 2020

Aim. The article is aimed at evaluating physiological adaptation (physical development, physical fitness and sickness rate) in first-year female university students not involved in sports to the urban conditions of the Kirov region. Materials and methods. Five hundred and thirty first-year female students not involved in sports (Vyatka State University, Kirov) participated in the study. Their physical development was estimated with the help of five anthropometric and eight physiometric parameters used for calculating 24 indices. To assess physical fitness, five types of tests were performed measuring general stamina, quickness, strength and other parameters. To evaluate the influence of urban environment, the participants were divided into three groups depending on the population of their home cities: “big city”, “small town”, “village”. Results. First-year female students, who used to live in a big city before entering the university, have smaller chest circumference at rest and at maximum inhalation/exhalation than the girls of the same height and weight, who used to live in small towns or villages. Urban environment influences physical fitness, which results in generally low stamina and strength typical for females living in Kirov. Conclusion. The results obtained show that the increase in urbanization puts pressure on the mechanisms of physiological adaptation in first-year female students who used to live in small towns and villages before entering the university.
PROTECTIVE MECHANISMS AGAINST HYPOXIA IN DIVING SIMULATION IN SWIMMERS
Authors: Podyacheva E , Zemlianukhina T , Simanovsky E , Fedorova E , Baranova T
Published: September 2020

Aim. The article deals with studying the systemic protective mechanisms of the brain against hypoxia during water immersion in highly skilled swimmers. Material and methods. 25 males aged 18–20 years were examined: 9 masters of sports, one master of sports of international class and 15 people not involved in sports. The study of cerebral blood flow was carried out by rheoencephalography (REG). REG was recorded at rest, when the face was immersed in water and during recovery. Examination was carried out 2 hours after the morning training session. In addition to cerebral blood flow, ECG and blood pressure were recorded at rest, during water immersion and recovery. Statistical data processing was performed using nonparametric Mann–Whitney and Wilcoxon criteria. Results. It was revealed that athletes at rest demonstrated more pronounced asymmetry of blood circulation and higher blood flow in the right hemisphere than people not involved in sports. However, during water immersion, the asymmetry disappears, blood flow improves, especially in the left hemisphere in the carotid artery territory as a result of a decrease in the tone of small vessels. In people not involved in sports, protective mechanisms are less pronounced. Conclusion. Vast experience in sports activities related to exercises performed in water and to training hypoxic exercises contributed to effective protective mechanisms against hypoxia based on the diving reflex.
DIGITALIZATION OF OPERATIONAL DIAGNOSTICS OF FUNCTIONAL RESERVES AND ASSESSMENT OF ATHLETIC FITNESS
Authors: Erlikh V , Shibkova D , Baiguzhin P
Published: September 2020

Aim. The article aims at analyzing the approaches to digitalization of operational diagnostics of functional reserves, assessing the athletic fitness for competitive activity, substantiating a model of multivariate analysis of the dynamic structure of mobilized reserves. Materials and methods. A theoretical analysis of the scientific publications on the development and implementation of digital technologies in sports physiology and medicine written by domestic and foreign authors over the past ten years has been conducted. Results. An analytical review of the literature indicates that hundreds of technologies for assessing the functional status and reserves introduced in a variety of software and hardware diagnostic systems and remote recorders have been deve­loped and implemented, most of which solve particular problems and do not reflect the multiparameter integration of athletic fitness for competitive activity; the author presents a conceptual model of multidimensional analysis of the dynamic structure of mobilized reserves with the subsequent formation of athletic fitness for competitive activity. Conclusion. The conceptual model can serve as the basis for creating a unified digital platform based on multiparameter integration, which will combine innovative achievements in operational assessment of the functional status, mobilization of reserves and athletic fitness for competitive activity.
THE CORRELATION BETWEEN MANUAL ASYMMETRY AND THE QUALITY OF BALL ROUTINE IN YOUNG GYMNASTS
Authors: Miasnikova T , Shvirid A
Published: September 2020

Aim. The article deals with establishing the correlation between lateral manual preference, manual technical asymmetry and the results of ball routine in young gymnasts. Materials and methods. Twenty gymnasts aged 7–8 years underwent tests to establish asymmetry through determining lateral manual preferences and assessing a ball routine performance. Non-parametric criteria and correlation analysis were used for data processing. Results. At the preparatory stage and at the stage of technique enhancement, the average level of the apparatus possession in the subgroups of gymnasts with different lateral manual preferences has statistically significant differences when performing technical elements with dominant and non-dominant hand (p ≤ 0.05). The correlation between lateral manual preferences and a ball routine performance in gymnasts was not revealed at the preparatory stage (ρ = –0.03) and was not significant at the stage of technique enhancement (ρ = 0.30). The coefficient of manual technical asymmetry has a significant correlation with the total amount of penalties for a ball routine technique at the preparatory stage (p < 0.05) and a highly significant correlation at the stage of technique enhancement (p < 0.01). Conclusion. Intergroup and individual differences in terms of symmetry/asymmetry should be taken into account for learning technical elements with the apparatus in young gymnasts.

Aim. The article deals with developing coordination abilities in equestrian athletes at the initial stage of training through a specially organized training process. Materials and methods. The study was conducted on the premises of the Grand Prix sports and recreation complex (Samara region, Podstepki village, Togliatti). 36 equestrian athletes aged from 16 to 17 years were examined. The main (MG) and the comparison group (CG) consisted of 18 males and females. The comparison group was engaged in a standard program (4 days per week, 1 hour). The main group had 4 training sessions per week. On the fourth day, the main group practiced specially selected exercises aimed at developing coordination abilities. The diagnostic method included the Human temporal and spatial properties analyzer 2.1 software, as well as the BALANCE SYSTEM SD training platform. Results. According to the results of the study, significant changes in the spatial and temporal properties were observed among triathletes and competitors in both males and females. The significance of differences of unilateral and bilateral postural stability confirms the importance of the ability to static and dynamic balance, as well as coordination and combination of movements for equestrian athletes involved in show jumping, dressage and eventing. Conclusion. Special exercises on the force platform allow improving coordination abilities, temporal and spatial properties and postural stability in show jumping, dressage and eventing.
The extended auxiliary equation mapping method to determine novel exact solitary wave solutions of the nonlinear fractional PDEs
Authors: Manafian Jalil , Ilhan Onur Alp , Avazpour Laleh
Published: September 2020

In this paper, some new nonlinear fractional partial differential equations (PDEs) have been considered.Three models are including the space-time fractional-order Boussinesq equation, space-time (2 + 1)-dimensional breaking soliton equations, and space-time fractional-order SRLW equation describe the behavior of these equations in the diverse applications. Meanwhile, the fractional derivatives in the sense of β-derivative are defined. Some fractional PDEs will convert to the considered ordinary differential equations by the help of transformation of β-derivative. These equations are analyzed utilizing an integration scheme, namely, the extended auxiliary equation mapping method. The different kinds of traveling wave solutions, solitary, topological, dark soliton, periodic, kink, and rational, fall out as a by-product of this scheme. Finally, the existence of the solutions for the constraint conditions is also shown. The outcome indicates that some fractional PDEs are used as a growing finding in the engineering sciences, mathematical physics, and so forth.
Swing shift: a mathematical approach to defensive positioning in baseball
Authors: Bouzarth Elizabeth , Grannan Benjamin , Harris John , Hartley Andrew , Hutson Kevin , Morton Ella
Published: September 2020

Defensive repositioning strategies (shifts) have become more prevalent in Major League Baseball in recent years. In 2018, batters faced some form of the shift in 34% of their plate appearances (Sawchik, Travis. 2019. “Don’t Worry, MLB–Hitters Are Killing The Shift On Their Own.” FiveThirtyEight, January 17, 2019. Also available at fivethirtyeight.com/features/dont-worry-mlb-hitters-are-killing-the-shift-on-their-own/). Most teams use a shift that overloads one side of the infield and adjusts the positioning of the outfield. In this work we describe a mathematical approach to the positioning of players over the entire field of play without the limitations of traditional positions or current methods of shifting. The model uses historical data for individual batters, and it leaves open the possibility of fewer than four infielders. The model also incorporates risk penalties for positioning players too far from areas of the field in which extra-base hits are more likely. This work is meant to serve as a decision-making tool for coaches and managers to best use their defensive assets. Our simulations show that an optimal positioning with three infielders lowered predicted batting average on balls in play (BABIP) by 5.9% for right-handers and by 10.3% for left-handers on average when compared to a standard four-infielder placement of players.
miR-300/FA2H affects gastric cancer cell proliferation and apoptosis
Authors: Hong Bo , Li Jie , Huang Chunxiao , Huang Tao , Zhang Mengpei , Huang Lijiang
Published: September 2020

MicroRNA (miR/miRNA) expression disorders play a crucial role in the development of gastric cancer (GC). Increasing evidence has indicated that miRNAs participate in the process of numerous cancers. Previous research has demonstrated that miR-300 acts as a cancer-promoting factor or tumor suppressor in a number of tumors. However, to the best of our knowledge, the effects of miR-300 on GC cells remain largely unknown. The present study investigated the effects of miR-300 on GC cells and analyzed its molecular mechanism. First, reverse transcription–quantitative polymerase chain reaction showed that miR-300 expression was increased in GC tissues and cell lines, with the highest expression observed in human gastric cancer cell line AGS. Subsequent results indicated that fatty acid 2-hydroxylase (FA2H) was a target of miR-300. FA2H-plasmid inhibited AGS cell proliferation and induced apoptosis. Finally, miR-300 inhibitor reduced cell proliferation and induced apoptosis, whereby these effects were reversed by FA2H-small interfering RNA. Therefore, the data demonstrated that miR-300/FA2H might be a new potential biomarker and therapeutic target for GC treatment.
Material Activity in Art and Design Practices
Authors: Franinović Karmen , Kirschner Roman
Published: September 2020

The theoretical movement of New Materialisms claims that society has to think differently about the way it treats our common material environment. The conception of matter as something active and transforming is at the core of these proposed changes. But in order to have an impact, conceptual frameworks must be accompanied by materially engaged practices. Recently, art and design projects have started bringing attention to active aspects of materials and environments. Our own research – in projects such as Enactive Environments and Liquid Things – concerns itself with chemical and biological processes, temporal aspects, and the openness of materials to environmental unpredictabilities.
Substanzaktivität. Farbe als prima materia im Andachtsbild der Frühen Neuzeit
Authors: Rath Markus
Published: September 2020

In devotional pictures of the Quattrocento by Giovanni di Francesco Toscani, Fra Angelico, Zanobi Strozzi, Benozzo Gozzoli, and Bartolomeo Caporali, floor and wall fields repeatedly appear as non-representational color grounds. They refer to a hitherto rather insufficiently analyzed multi-layered reflection of the design modes of the time. These surfaces only superficially resemble natural stone structures. Rather, they are coloristic protoforms of the pictorial figurations, which is why these color fields, apart from a theological sub-iconography, can also be understood as references to the substrate character of the color. By evoking spiral and snail shapes in addition to completely amorphous spots, they also seem to reflect the processes of rock formation as explored in Albertus Magnus’s De mineralibus. As a fluid matter that can develop spontaneously into any form in the sense of a painterly generatio spontanea, color finally approximates the Aristotelian concept of hylē. This contribution seeks to explore the exciting and dynamic relationship between matter and form in the quattrocentesque devotional picture. The color substance of the amorphous grounds is understood as an activated source material that is transformed into vivid forms by way of the respective artistic technē.

A phytochemical investigation of the stem bark of Calophyllum canum resulted in the isolation of a new xanthone dimer identified as biscaloxanthone (1), together with four compounds; trapezifoliaxanthone (2), trapezifolixanthone A (3), taraxerone (4) and taraxerol (5). The structures of these compounds were determined via spectroscopic methods of IR, UV, MS and NMR (1D and 2D). The cytotoxicity of compounds 1–3 were screened against A549, MCF-7, C33A and 3T3L1 cell lines, wherein weak cytotoxic activities were observed (IC50 > 50 μm).
Reporting Grantee Demographics for Diversity, Equity, and Inclusion in Neuroscience
Authors: Choudhury Suparna , Aggarwal Neil K.
Published: September 2020

Professional neuroscience organizations have recently pledged their commitments to diversity, equity, and inclusion in examining institutional discrimination; to raise questions about how to train underrepresented scientists; and to recruit underrepresented subjects for a more equitable scientific enterprise in the 21st century. Studies have illuminated racial disparities in funding, likely because of implicit bias in the review process and differential access to resources. We propose that one concrete way to monitor and redress these disparities is to collect and publicize data on grantees by gender, race, ethnicity, and location from neuroscience funding agencies. Beyond remedying historical disadvantages, disseminating funding more equitably across recipients would be an empirical solution that can improve the very quality of neuroscience.
Study design: what’s in a name?
Authors: Dekkers Olaf M , Groenwold Rolf H H
Published: September 2020

The name of the study should properly reflect the actual conduct and analysis of the study. This short paper provides guidance on how to properly name the study design. The first distinction is between a trial (intervention given to patients to study its effect) and an observational study. For observational studies, it should further be decided whether it is cross-sectional or whether follow-up time is taken into account (cohort or case–control study). The distinction prospective-retrospective has two disadvantages: prospective is often seen as marker of higher quality, which is not necessarily true; there is no unifying definition that makes a proper distinction between retrospective and prospective possible.
A Multivariate Poisson Deep Learning Model for Genomic Prediction of Count Data
Authors: Montesinos-López Osval Antonio , Montesinos-López José Cricelio , Singh Pawan , Lozano-Ramirez Nerida , Barrón-López Alberto , Montesinos-López Abelardo , Crossa José
Published: September 2020

The paradigm called genomic selection (GS) is a revolutionary way of developing new plants and animals. This is a predictive methodology, since it uses learning methods to perform its task. Unfortunately, there is no universal model that can be used for all types of predictions; for this reason, specific methodologies are required for each type of output (response variables). Since there is a lack of efficient methodologies for multivariate count data outcomes, in this paper, a multivariate Poisson deep neural network (MPDN) model is proposed for the genomic prediction of various count outcomes simultaneously. The MPDN model uses the minus log-likelihood of a Poisson distribution as a loss function, in hidden layers for capturing nonlinear patterns using the rectified linear unit (RELU) activation function and, in the output layer, the exponential activation function was used for producing outputs on the same scale of counts. The proposed MPDN model was compared to conventional generalized Poisson regression models and univariate Poisson deep learning models in two experimental data sets of count data. We found that the proposed MPDL outperformed univariate Poisson deep neural network models, but did not outperform, in terms of prediction, the univariate generalized Poisson regression models. All deep learning models were implemented in Tensorflow as back-end and Keras as front-end, which allows implementing these models on moderate and large data sets, which is a significant advantage over previous GS models for multivariate count data.

The five hardwoods showed significant differences in the content and composition of the main families of extractives, namely fatty acids, long chain aliphatic alcohols and sterols. Significant differences in the composition persist after wood pulping and ECF bleaching of pulps. The fate of the various types of extractives during the wood and pulp processing is discussed. Long chain aliphatic acids and alcohols are quite stable during the pulp production and are retained to a great extent in the final bleached pulp; delta 5 sterols are mostly oxidised and partially retained in the pulps, while delta 7 sterols are completely degraded and/or dissolved. B. verrucosa and A. mangium bleached pulps show contents of fatty acids about 4 and 20 times higher than that of Eucalyptus pulps, respectively, while the content of long chain aliphatic alcohols in A. mangium pulp is of the order of 100 times higher than Eucalyptus and B. verrucosa pulps.
Chemical modification of pine wood with propionic anhydride: Effect on decay resistance and sorption of water vapour
Authors: Papadopoulos Antonios N.
Published: September 2020

The purpose of this paper is to show the effects of level of substitution with a linear chain anhydride (propionic anhydride) on decay resistance and on water vapour sorption of modified Scots pine sapwood. The work described herein has demonstrated that chemically modified Scots pine sapwood with propionic anhydride afforded substantial bioprotection against Coniophora puteana . It required a weight gain of approximately 17% following reaction to ensure complete protection. The sorption of water vapour of propionic anhydride modified wood was greatly reduced.

Published: September 2020

BACKGROUND AND OBJECTIVES:

Genetic testing is recommended for individuals with autism spectrum disorder (ASD). Pathogenic yield varies by clinician and/or patient characteristics. Our objectives were to determine the pathogenic yield of genetic testing, the variability in rate of pathogenic results based on subject characteristics, and the percentage of pathogenic findings resulting in further medical recommendations in toddlers with a Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition diagnosis of ASD.

METHODS:

We conducted a retrospective chart review of 500 toddlers, 18 to 36 months, diagnosed with Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition ASD (mean age: 25.8 months, 79% male). Subject demographics, medical and neuropsychological characteristics, and genetic test results were abstracted. Genetic results were divided into negative or normal, variants of unknown significance, and pathogenic. Subject characteristics were compared across results. Manual chart review determined if further recommendations were made after pathogenic results.

RESULTS:

Over half of subjects (59.8%, n = 299) completed genetic testing, and of those, 36 (12.0%) had pathogenic findings. There were no significant differences in Bayley Scales of Infant Development cognitive (P = .112), language (P = .898), or motor scores (P = .488) among children with negative or normal findings versus a variant of unknown significance versus pathogenic findings. Medical recommendations in response to the genetic finding were made for 72.2% of those with pathogenic results.

CONCLUSIONS:

Our findings reinforce the importance of genetic testing for toddlers diagnosed with ASD given the 12% yield and lack of phenotypic differences between subjects with and without pathogenic findings. The majority of pathogenic results lead to further medical recommendations.

Background and aims

Persimmon (Diospyros kaki) is an economically
important fruit tree species with complex flowering characteristics. To obtain
accurate expression pattern analysis results, it is vital to select a reliable gene
for the normalization of real-time quantitative polymerase chain reaction data. The
aim of this study was to identify the optimal internal control gene among six
candidate genes for gene expression analysis in different persimmon organs and
developmental stages.

Materials and methods

This analysis was conducted using geNorm and NormFinder software to show
differences in the stability of the six reference genes among tissues and floral
developmental stages of the same plant.

Results

Although genes that exhibited moderate expression in NormFinder revealed
slightly different expression stabilities than those obtained by geNorm, both sets of
results showed that GAPDH was the best reference gene in
different organs and floral buds at different developmental stages, whereas
18SrRNA was the least stable gene.

Conclusions

Based on the overall ranking, GAPDH is the most
suitable reference gene and is highly recommended for gene expression studies in
different organs and different developmental stages of persimmon. This study provides
useful reference data for future gene expression studies and will contribute to
improving the accuracy of gene expression results in persimmon.

Purpose

This study aims to characterize plant growth-promoting rhizobacteria (PGPR) in
sunflowers growing in different locations at North West of Iran.

Materials and methods

Sunflower plants were collected from different regions of West Azarbaijan, and
rhizospheric bacterial strains were isolated and screened for PGP traits.
Identification and characterization of the PGPR were conducted based on 16s rDNA
sequences and phenotypic analysis, the strains clustered for genetic diversity by
rep-PCR method.

Results

Among the 80 bacterial isolates, 20 showed PGP traits and were selected for
other potentials. All the selected isolates produced indole-3-acetic acid at the rate
of 9.2–33.7 mg/ml. In addition, 13, 15, 12, and 16 were positive for phosphate
solubilization, siderephore, hydrogen cyanide, and ammonia production, respectively.
The results from a subsequent pot experiment indicated that PGPRs distinctly increased
sun flower shoot and root length, shoot and root fresh weight, as well as shoot and
root dry weight. Based on 16S rDNA sequences and biochemical and physiological
characteristics, 20 PGPRs were identified as Pseudomonas
fluorescens (five isolates), Pseudomonas
aeruginosa (four isolates), Pseudomonas
geniculata (one isolate), Bacillus subtilis
(four isolates), Bacillus pumilus (two isolates),
Stenotrophomonas maltophilia (two isolates), and
Brevibacterium frigoritolerans (two isolates). In
rep-PCR, PGPR isolates were differentiated into seven clusters (A–G) at 65% similarity
level. These results demonstrated the existence of a considerable species richness and
genetic diversity among PGPRs isolated from different regions of North West of
Iran.

Conclusions

To the best of our knowledge, this is first report for the identification and
characterization of B. frigoritolerans as PGPR in sunflower
plants.

Limbah pelepah sawit (LPS) dihasilkan secara periodik dari perkebunan kelapa sawit. Keberadaan LPS ini berpeluang digunakan sebagai bahan baku adsorben. LPS telah diubah menjadi arang aktif pelepah sawit (APS) melalui langkah karbonisasi pada temperatur 600oC selama waktu bervariasi (30, 60, dan 120 menit). APS yang diperoleh dilakukan analisis kadar air, abu dan zat menguap. APS juga dikarakterisasi dengan FTIR untuk menentukan gugus fungsi, keasaman permukaan dengan tirasi Bhoem serta SEM untuk mendeteksi morfologi permukaan. Kemampuan APS untuk menjerap asam lemak bebas (ALB) dari CPO dipelajari pada waktu adsorpsi dan dosis adsorben yang bervariasi. Hasil penelitian menunjukkan bahwa semua APS memiliki kadar air, abu dan zat menguap yang sangat rendah, sehingga memenuhi SNI 06-3730-1995. Gugus fungsi yang dimiliki APS di antaranya C-O, O-H, C-O-C, C=O, C-C (aromatik) dan C-H. APS mengandung 14 mmolg-1 total asam dengan mayoritas asam fenolat sebanyak 12,3 mmolg-1, sisanya sebagai asam karboksilat dan laktonat. Morfologi permukaan arang aktif membentuk rongga-rongga dengan ukuran yang semakin besar dan tersusun rapat seiring dengan lamanya waktu karbonisasi. Hasil uji adsorpsi ALB yang paling baik ditunjukkan oleh APS60 yang mampu menjerap hingga 77,8% ALB pada waktu adsorpsi 60 menit dan 1 g  dosis adsorben. Dengan demikian, LPS layak dikembangkan menjadi arang aktif dan digunakan sebagai adsorben untuk mengurangi kadar asam lemak bebas dalam CPO.
