Risk of hepatocellular carcinoma among individuals with different aetiologies of cirrhosis: a population‐based cohort study
Authors: West J. , Card T. R. , Aithal G. P. , Fleming K. M.
Published: February 2017

Background

Among patients with cirrhosis, only those determined to be at risk for hepatocellular carcinoma (HCC) should undergo surveillance. However, little is known about how different aetiologies of cirrhosis affect risk for HCC.

Aim

To quantify the cumulative incidence of HCC among a representative population of people with cirrhosis of the liver of varying aetiology.

Methods

We identified subjects with hepatic cirrhosis from the UK's General Practice Research Database (1987–2006). Diagnoses of HCC were obtained from linked national cancer registries (1971–2006). Cox proportional hazards regression was used to estimate hazard ratios. The predicted 10‐year cumulative incidence of HCC for each aetiology of cirrhosis was estimated while accounting for competing risks of death from any cause and liver transplant.

Results

Among 3107 people with cirrhosis, the adjusted relative risk of HCC was increased twofold to threefold among people with viral and autoimmune/metabolic aetiologies, compared to those with alcohol‐associated cirrhosis. The 10‐year predicted cumulative incidence estimates of HCC for each aetiology were alcohol, 1.2%; chronic viral hepatitis, 4.0%; autoimmune or metabolic disease, 3.2%; and cryptogenic, 1.1%.

Conclusions

In a population‐based study in the UK, people with cirrhosis have an estimated cumulative 10‐year incidence of HCC of 4% or lower. Cumulative incidence varies with aetiology such that individuals with alcohol or cryptogenic cirrhosis have the lowest risk for HCC. These findings provide important information for cost‐effectiveness analyses of HCC surveillance.
Genetic and demographic founder effects have long‐term fitness consequences for colonising populations

Published: February 2017

Colonisation is a fundamental ecological and evolutionary process that drives the distribution and abundance of organisms. The initial ability of colonists to establish is determined largely by the number of founders and their genetic background. We explore the importance of these demographic and genetic properties for longer term persistence and adaptation of populations colonising a novel habitat using experimental populations of Tribolium castaneum. We introduced individuals from three genetic backgrounds (inbred – outbred) into a novel environment at three founding sizes (2–32), and tracked populations for seven generations. Inbreeding had negative effects, whereas outbreeding generally had positive effects on establishment, population growth and long‐term persistence. Severe bottlenecks due to small founding sizes reduced genetic variation and fitness but did not prevent adaptation if the founders originated from genetically diverse populations. Thus, we find important and largely independent roles for both demographic and genetic processes in driving colonisation success.

Authors: Theiner Y. , Drexel M. , Neuner M. , Hofstetter G.
Published: February 2017

A comprehensive study of the time‐dependent behaviour of concrete, enhanced by measuring the evolution of the respective mass water content, is presented. Compressive creep as well as shrinkage are investigated on sealed and unsealed specimens in terms of the concrete age at loading of 2, 7, and 28 days, respectively, at a loading level of 30% of the compressive strength at loading. In addition, on the basis of the collected measurement data, the impact of load application on the moisture content is studied and the Pickett effect is re‐examined. The obtained set of material data consists of basic and drying creep strains for different concrete ages at loading, autogenous shrinkage strains as well as combined autogenous and drying shrinkage strains, the evolution of the mass water content, the water desorption isotherm, and the time‐dependent evolution of Young's modulus and the compressive strength. It provides a consistent set of material data for a particular concrete grade and will be available for calibrating and validating concrete models.
The Relationship between Professional Learning Community and Lesson Study: A Case Study in Low Performing Schools in Sabah, Malaysia
Authors: Ansawi Bitty , Pang Vincent
Published: February 2017

Education plays an important role in the development of a nation. Teachers, the main implementer of curriculum at school are subjected to numerous approaches and strategies which have been proven to bring about positive and significant change in students’ academic performance. However, the success of these programs depends on the positive perception of these programs. This study aims to identify how lesson study relates to professional learning community practice in the school. A total of 98 teachers selected via purposive sampling from low performing schools in Sabah. Two scales were adapted from past studies to measure the respondents’ perception about professional learning community and lesson study practices. Data from the questionnaire was analyzed with IBM SPSS 23.0. Findings showed that teachers perceived both professional learning community and lesson study practices highly. Lesson study and professional learning community showed significant positive and strong relationship. This study implied that teachers in low performing school are receptive of these practices and such attitude may contribute to the success of the SISC+ program in these schools. Findings from this study help policy makers and practitioners to plan strategically on the implementation of these practices in schools.
A Novel Decomposition-Based Evolutionary Algorithm for Engineering Design Optimization
Authors: Shankar Bhattacharjee Kalyan , Kumar Singh Hemant , Ray Tapabrata
Published: February 2017

In recent years, evolutionary algorithms based on the concept of “decomposition” have gained significant attention for solving multi-objective optimization problems. They have been particularly instrumental in solving problems with four or more objectives, which are further classified as many-objective optimization problems. In this paper, we first review the cause-effect relationships introduced by commonly adopted schemes in such algorithms. Thereafter, we introduce a decomposition-based evolutionary algorithm with a novel assignment scheme. The scheme eliminates the need for any additional replacement scheme, while ensuring diversity among the population of candidate solutions. Furthermore, to deal with constrained optimization problems efficiently, marginally infeasible solutions are preserved to aid search in promising regions of interest. The performance of the algorithm is objectively evaluated using a number of benchmark and practical problems, and compared with a number of recent algorithms. Finally, we also formulate a practical many-objective problem related to wind-farm layout optimization and illustrate the performance of the proposed approach on it. The numerical experiments clearly highlight the ability of the proposed algorithm to deliver the competitive results across a wide range of multi-/many-objective design optimization problems.
Multiscale Validation and Uncertainty Quantification for Problems With Sparse Data

Published: February 2017

Quantification of uncertainty in the simulation results becomes difficult for complex real-world systems with little or no experimental data. This paper describes a validation and uncertainty quantification (VUQ) approach that integrates computational and experimental data through a range of experimental scales and a hierarchy of complexity levels. This global approach links dissimilar experimental datasets at different scales, in a hierarchy, to reduce quantified error bars on case with sparse data, without running additional experiments. This approach was demonstrated by applying on a real-world problem, greenhouse gas (GHG) emissions from wind tunnel flares. The two-tier validation hierarchy links, a buoyancy-driven helium plume and a wind tunnel flare, to increase the confidence in the estimation of GHG emissions from wind tunnel flares from simulations.
Biological nitrogen fixation and plant growth promotion of lodgepole pine by an endophytic diazotroph Paenibacillus polymyxa and its GFP-tagged derivative

Published: February 2017

Paenibacillus polymyxa P2b-2R is an endophytic diazotroph originally isolated from lodgepole pine. It is reported to fix significant amounts of nitrogen (N) and promote plant growth. To evaluate the endophytic colonization sites, a green fluorescent protein (GFP) derivative of P2b-2R was generated (P2b–2Rgfp), but the effects of GFP modification on the functioning of P2b-2R have not been fully elucidated yet. In this study, we wanted to confirm and contrast the N-fixing and plant-growth-promoting abilities of P2b-2Rgfp with those of the wild-type P2b-2R in lodgepole pine. Pine seedlings were grown in an N-limited environment and harvested 2, 4, 8, and 12 months after inoculation to evaluate the endophytic and rhizospheric colonization by both strains, the amount of N-fixed, and seedling growth enhancement. Both P2b-2R and P2b-2Rgfp strains formed persistent rhizospheric and endophytic populations; fixed N; and enhanced seedling growth continuously after 4 months. P2b-2Rgfp-treated seedlings outperformed the P2b-2R-treated seedlings in terms of biomass only during the initial stages of plant development, but the differences decreased during the trial and were not significant towards the end. To the best of our knowledge, this is the first study that reports the effects of GFP-tagging of an endophyte when inoculated into a gymnosperm tree species.
Structural, vibrational (FTIR and FT-Raman), NMR, UV–vis spectral analysis, and DFT study of 2-(6-oxo-2-thioxotetrahydropyrimidin-4(1H)-ylidene) hydrazine carboxamide
Authors: Kalaiarasi N. , Manivarman S.
Published: February 2017

Vibrational and spectral characterizations of 2-(6-oxo-2-thioxo tetrahydro pyrimidin-4(1h)-ylidene) hydrazine carboxamide (OTHHPYHC) were experimentally presented for the ground state using FTIR and FT-Raman and theoretically presented by density functional theory (DFT) using B3LYP correlation function with the basis set 6-31G(d,p). The geometrical parameters, energies, and wavenumbers have been obtained. The fundamental assignments were performed on the basis of total energy distribution. The first order hyperpolarizability (β0) and relative properties (β, α0, and Δα) were calculated using B3LYP/6-31G(d, p) method. Solidity of the molecule due to hyperconjugative interactions and charge delocalization has been analysed using natural bond orbital (NBO) analysis. The charge distribution and electron transfer from bonding to antibonding orbitals and electron density in the σ* and π* antibonding orbitals confirms interaction within the molecule. In addition to this, Mulliken population and HOMO–LUMO analysis have been used to support the information of structural properties.
Coherent states and localization in a quantized discrete NLS lattice
Authors: Martinez-Galicia R. , Panayotaros Panayotis
Published: February 2017

We study the evolution of a quantum discrete nonlinear Schrödinger (DNLS) system using as initial conditions coherent states corresponding to points in the vicinity of breather solutions of the classical system. We consider various examples of stable and unstable breathers and examine the distance between exactly evolved states and coherent states with parameters that evolve according to classical dynamics. Initial conditions near stable breathers and their vicinity are seen to lead to recurrences to small distances between the two evolving states. Similar recurrences are not observed for initial conditions near unstable breathers.

Published: February 2017

The 70-m DSN’s Deep Space Station antenna 14 (DSS-14) at Goldstone has recently been outfitted with instrumentation to enable pulsar searching and timing operation. Systems capable of similar operations are undergoing installation at DSS-63, and are planned for DSS-43. The Goldstone system is the first of these to become operational with a 640[Formula: see text]MHz bandwidth stretching from 1325–1965[Formula: see text]MHz. Initial results from the pulsar timing pipeline show short-term residuals of [Formula: see text][Formula: see text]ns for pulsar B1937+21. Commissioning observations at DSS-14 to obtain a baseline set of time of arrival (TOA) measurements on several millisecond pulsars (MSPs) are currently underway.
A Perspective of Evolution for Carbon Emissions Trading Market: The Dilemma between Market Scale and Government Regulation
Authors: Zhu Qi
Published: February 2017

Which means are more effective for reducing carbon emission? Our paper argues the effect of the government regulation and the market trading on the carbon emission. Based on our model, we obtain three conclusions as follows. First, government strengthened regulation can encourage firms to participate in the trading market for carbon emission. Second, there is the negative relation of supervision cost to trading price. Third, there is an alternative relationship between the scale economy level of the supervisory authority and that of the carbon emissions market. Meanwhile, our numerical simulations also confirm our results for our model analyses.
Fuzzy Adaptive Shift Schedule of Tractor Subjected to Random Load
Authors: Cao Qingmei , Zhou Zhili , Zhang Mingzhu
Published: February 2017

In this paper, the low frequency random load of a tractor is presented. Controlled by a theoretical three‐parameter shift schedule, the random load would frequently trigger the random shift. Simultaneously, the driving force of the tractor should be consistent prior to and following this shift. Additionally, the higher traction efficiency and improved load utilization rate should be ensured by a choice of a transmission ratio of the tractor power shift transmission. The shift schedule was utilized for the aforementioned problems solution. An innovative method is presented for theoretical shift schedule modification by the fuzzy algorithm, based on the random load standard deviation and the alteration rate of both steady state values of the load and of the throttle position. The simulation results demonstrated that the modified shift schedule could discover the running state of the tractor. By shielding the random shift judgment caused by the random load, the stability of the tractor was ensured. When the shift was required, the schedule could rapidly respond, whereas the tractor driving force did not sustain a sudden alteration. The schedule could also automatically select and maintain the transmission ratio with higher traction efficiency.

Balinese people have one of the civilization history and cultural heritage are handwritten in Balinese script on palm leaves known as Balinese Papyrus (LontarAksara Bali). Until now that cultural heritage is still continuously strived its preservation along with the implementation begin to be abandoned in public life. Some of Balinese Papyrus now begin to rot and fade under influenced by age. Information technology utilization can be a tool to solve the problems faced in the preservation of the Balinese papyrus. By using digital image processing techniques, the papyrus script can be reconstructed digitally so that it can be retrieved and store the content in the digital media. Balinese papyrus reconstructed through several processes from scanning into a digital image, performing preprocessing for image quality improvement, segmenting the Balinese characters on image, doing character recognition using LDA algorithm, rearranging the result of recognition in accordance with the original content in papyrus, and translating that characters result into Latin. LDA algorithm quite successfully performs the classification associated with handwritten character recognition.
Government Support and R&D Investment Effectiveness in Chinese SMEs: A Complex Relationship
Authors: Petti Claudio , Rubini Lauretta , Podetti Silvia
Published: February 2017

This paper investigates the combined role of innovation support policies and firm's own innovative activities on the performance of Chinese small- and medium-sized enterprises (SMEs) in high-tech sectors. By distinguishing two components of innovative activities—research and development (R&D) investments and embedded innovative capacity—the paper develops and tests an integrative moderated moderation model. The results suggest that in Chinese high-tech SMEs innovation-support policies positively moderate the relationship between R&D investments and performance, but this positive effect diminishes when there are higher levels of embedded innovative capacity. These results highlight that the relationship between government innovation policies and a firm's own R&D investments is not only reciprocal but also more complex than the one so far analyzed in the literature. The results show in particular that the effects of innovation-support policies on R&D investments is not as neat as it seems, because of the internal balance within the firm between investment in R&D and other sources of innovation. Therefore, although innovation support policies have been found to help Chinese SMEs in high-tech sectors benefit from their R&D investments, these policies are particularly effective only when R&D investments are significantly driving firms’ innovative activities. This highlights the relevance of both government support and a firm's own efforts in the competitive modernization of Chinese SMEs.
Creating a Religious Community in Siberia
Authors: Thyrêt Isolde
Published: February 2017

This article explores how Nektarii, the third archbishop of Siberia and Tobolsk (1636–1640), contributed to the creation of a lasting Russian Orthodox community in his diocese by manipulating traditional Muscovite social rituals and the Russian Orthodox practice of venerating miracle-working icons. Challenging the traditional view that the conversion of Siberia was guided primarily by Muscovite imperial policy, Thyrêt instead focuses on local religious developments that were initiated by the Siberian hierarch in order to deal with obstreperous government officials and the unruly flock of his border diocese. The article shows how Nektarii creatively established his ecclesiastical authority in Tobolsk and laid the foundation for a community following a regulated Christian life in Siberia by connecting his arrival in Tobolsk with an impressive ceremonial entrance that was styled after royal welcoming rituals and by engineering the cult of the first Siberian miracle-working icon, the image of the Virgin of Abalak.

Published: February 2017

‘Psychobiotics’ is your new word this month: live microorganisms with mental health benefits. We've previously noted the links between the gut microbiome and changes in cognition and psychopathology. Now, Allen and colleagues test an intervention – using the bacterium Bifidobacterium longum 1714 – in 22 healthy volunteers who undertook cognitive assessments, resting electro-encephalography (EEG), and a social stress test at baseline, post-placebo, and post-psychobiotic. The active intervention was associated with reduced cortisol levels and subjective anxiety in response to the stress test, as well as lower levels of self-reported stress. It also resulted in enhanced frontal midline EEG mobility, which is representative of prefrontal cortical activity, and modest improvements in visuospatial memory performance. The authors propose a precision strategy, to rationally test particular candidate bacteria strains – rather than the ‘probiotic cocktail’ often administered – against specific psychopathology.

How Russian Soft Power Fails in Estonia: Or, Why the Russophone Minorities Remain Quiescent
Authors: Nielsen Kristian , Paabo Heiko
Published: February 2017

This article evaluates the significance of Russian soft power in Estonia, particularly in connection to the minority issue, and compares this soft power to the countervailing pull of the European Union on the other side. It concludes that although Russia does indeed have a number of soft power resources, their potential for being translated into actual power and influence is too often exaggerated, not least because Europe provides a much more attractive focus point for the disgruntled than Moscow. Moreover, Estonia has it fully within its power to bolster its own attractiveness in the eyes of the minority populations. Thus, although relations with Russia should be handled with care, it is not Russia’s soft power that should be feared.

The Featurization of Journalism
Authors: Steensen Steen
Published: February 2017

Feature journalism has developed from being an insignificant supplement to news journalism to a family of genres that today dominates newspapers. The present article explores the growing importance of feature journalism and attempts to understand its social function, how it has changed and why it has become so important. Based on an analysis of influential textbooks on feature journalism, the paper argues that feature journalism has traditionally been dominated by a literary discourse, and discourses of intimacy and adventure – discourses that thus have become increasingly important for newspapers, thereby transforming the social function of news in general. Today, however, the genres of feature journalism are undergoing significant changes, reflecting the technological, social, economic and cultural changes that affect the media industry and the role of journalism at large. The present article is framed by a social constructivist view of genre, and it outlines possible scenarios for future transformations of feature journalism.
The World on Television
Authors: Ihlen Øyvind , Allern Sigurd , Thorbjørnsrud Kjersti , Waldahl Ragnar
Published: February 2017

How does television cover foreign news? What is covered and how? The present article reports on a comparative study of a license-financed public broadcaster and an advertising-financed channel in Norway – the NRK and TV2, respectively. Both channels give priority to international news. While the NRK devotes more time to foreign news (both in absolute and relative numbers) than TV2 does, other aspects of the coverage are strikingly similar: The news is event oriented, there is heavy use of eyewitness footage, and certain regions are hardly visible. At least three explanations can be used to understand these findings: the technological platform (what footage is available, etc.) and the existence of a common news culture that is based on ratings and similar views on what is considered “good television”. A third factor is that both channels still have public service obligations.

was to present our experience with the postauricular island flap (pif) and clinical evaluation of the results following auricular conchal bowl reconstructions with the pif in patients after carcinoma resections.

We analyzed results in 13 patients who underwent auricular conchal bowl reconstructions with pif following malignant tumor resection between 2000-2013. The patients were followed-up. We estimated early and long-term results after surgery including plastic surgeon’s and patient’s opinion.

The malignancies were completely excised in all patients, and there were no recurrences within 2 years of follow-up. Observed complications of conchal bowl reconstructions were venous congestion in two cases (15.3 %), and pinning of the operated ear in two patients (15.3%). Postoperative result was very good in 11 cases (both in the opinion of plastic surgeon and patients), whereas in two patients with pinning of the operated ear was satisfied.

1. Postauricular island flap reconstructions after auricular conchal bowl resections allowed for complete removal of malignant tumors with no evidence of recurrence, and also preserved proper conchal shape in the reconstructed ear. 2. Reconstructions of auricular conchal bowl with the postauricular island flap resulted in very good postoperative results, which confirms the efficiency of the applied technique. 3. Reconstructive surgery with postauricular island flap of individuals with partial auricular conchal bowl defects contributed to postoperative satisfaction in both patients and doctors’ estimations.
Report on Green Frog (Euphlyctis hexadactylus) from Vengaivasal Lake (Tamilnadu, India)
Authors: Ramanibai Ravichandran , Govindan Sivalingam
Published: February 2017

Through the Visual Encounter Survey only one species of green frog (Euphlyctis hexadactylus) was encountered. As we lack previous data we cannot comment on the decline of the species. Frogs, known for specific habitats, are under threats if such habitats are lost. The physico-chemical parameters estimated along with the anuran survey reported that the quality of the lake is not congenial to support the tadpoles of the frogs. The adults can move away from water and survive on land. The habitat, as well as the surrounding wetland, plays a vital role to support a good quantum of anurans.
Single-Molecule Sequencing of the Drosophila serrata Genome

Published: February 2017

Long-read sequencing technology promises to greatly enhance de novo assembly of genomes for nonmodel species. Although the error rates of long reads have been a stumbling block, sequencing at high coverage permits the self-correction of many errors. Here, we sequence and de novo assemble the genome of Drosophila serrata, a species from the montium subgroup that has been well-studied for latitudinal clines, sexual selection, and gene expression, but which lacks a reference genome. Using 11 PacBio single-molecule real-time (SMRT cells), we generated 12 Gbp of raw sequence data comprising ∼65 × whole-genome coverage. Read lengths averaged 8940 bp (NRead50 12,200) with the longest read at 53 kbp. We self-corrected reads using the PBDagCon algorithm and assembled the genome using the MHAP algorithm within the PBcR assembler. Total genome length was 198 Mbp with an N50 just under 1 Mbp. Contigs displayed a high degree of chromosome arm-level conservation with the D. melanogaster genome and many could be sensibly placed on the D. serrata physical map. We also provide an initial annotation for this genome using in silico gene predictions that were supported by RNA-seq data.

Ensino de História e formação de professores: narrativas de educadores
Authors: Cunha Jorge Luiz da , Cardôzo Lisliane dos Santos
Published: February 2017

Este artigo tem como objetivo investigar a profissão do educador de História, através de sua identidade narrativa. Nesta pesquisa, buscamos relacionar a formação inicial do educador com a percepção que tem da docência. Para isto, entrevistamos professores da disciplina de História das escolas públicas da cidade de Santa Maria, RS, tendo como metodologia a história oral de vida. A pesquisa mostrou que a formação inicial tem um papel central na constituição de posturas teóricas, práticas pedagógicas e na identidade profissional. A principal crítica apontada nas narrativas sobre a formação inicial relaciona-se à dicotomia entre teoria e prática. Entretanto, a percepção do educador acerca da sua profissão não fica restrita aos processos de formação formal, sendo influenciada pelas trajetórias pessoal e profissional, tendo sua gênese na história de vida dos entrevistados: na escolha da profissão e na imagem que se tem, a priori, da docência. A partir dessas reflexões, apontamos a necessidade de rever paradigmas que norteiam as práticas de formação de professores de história.

One of the best selling products sold in online stores are fashion products whereas such products are experience goods. The purpose of this study was to analyze and discuss the influence of the products quality , eases, and prices  on the repurchase intention and satisfaction as an intervening variable. Satisfaction was measured by several drivers of satisfaction to determine the extent of repurchase intention made by fashion product customer. Respondents in this study were women and men aged 20- 40 years who have made purchases of fashion products in online store at least twice with the last purchase is within the last six month. The sampling method used was non probability sampling and sampling techniques used was judgmental sampling. The sample used in this research was 210. Data collection technique used in this study was questionnaire. Data were analyzed using path analysis with AMOS program. The results of this study indicate that the product quality, ease, and price have a significant effect on satisfications. Ease significantly influence the repurchase intentions While the quality of the product does not affect the repurchase intentions and the price negatively affect of the repurchase intention. The results of this study also show that the product quality, ease, and price has indirect influence on repurchase intentions and  through satisfaction as mediating variables. But, the first mediation test (product quality) was proven to be  fully mediating while the ease and price was proven to be partially mediating.

Published: February 2017

Впервые выращен эпитаксиальный теллурид кадмия толщиной 1-3 mum на кремнии с буферным слоем карбида кремния методом открытого термического испарения и конденсации в вакууме. Оптимальная температура подложки составила 500oC при температуре испарителя 580oC, время роста 4 s. Для более качественного роста теллурида кадмия на поверхности кремния предварительно был синтезирован методом топохимического замещения атомов высококачественный буферный слой карбида кремния толщиной ~100 nm. Эллипсометрический, рамановский, рентгеновский и электронографический анализ показали высокое структурное совершенство слоя CdTe и отсутствие поликристаллической фазы. Работа выполнена при финансовой поддержке Российского научного фонда (грант N 14-12-01102). Исследования проводились при использовании оборудования Уникальной научной установки (УНО) "Физика, химия и механика кристаллов и тонких пленок" ФГУН ИПМаш РАН. DOI: 10.21883/FTT.2017.02.44067.288

Исследованы размеры элементов структуры, образованной наночастицами коллоидного раствора магнетита под действием магнитного поля. При освещении тонкого слоя такой жидкости сфокусированным лазерным пучком наблюдалась картина, характерная для дифракции на бесконечно длинном диэлектрическом цилиндре, что было использовано для измерения толщины отдельных агрегатов. Эти данные оказались хорошо согласованными с оценкой, выполненной методом оптической микроскопии. DOI: 10.21883/PJTF.2017.04.44294.16554

Authors: Seankham Soraya , Novalin Senad , Pruksasri Suwattana
Published: February 2017

Activated charcoal was applied for the recovery of lactic acid in undissociated form from fermentation broth. Lactic acid was obtained from the fermentation of Lactobacillus casei TISTR 1340 using acid hydrolyzed Jerusalem artichoke as a carbon source. The equilibrium adsorption isotherm and kinetics for the lactic acid separation were investigated. The experimental data for lactic acid adsorption from fermentation broth were best described by the Freundlich isotherm and the pseudo-second order kinetics with R2 values of 0.99. The initial adsorption rate was 41.32 mg/g?min at the initial lactic acid concentration of 40 g/L.
