Scientific fake papers, containing manipulated or completely fabricated data, are a problem that has reached dramatic dimensions. Companies known as paper mills (or more bluntly as "criminal science publishing gangs") produce and sell such fake papers on a large scale. The main drivers of the fake paper flood are the pressure in academic systems and (monetary) incentives to publish in respected scientific journals and sometimes the personal desire for increased "prestige." Published fake papers cause substantial scientific, economic, and social damage. There are numerous information sources that deal with this topic from different points of view. This review aims to provide an overview of these information sources until June 2024. Much more original research with larger datasets is needed, for example on the extent and impact of the fake paper problem and especially on how to detect them, as many findings are based more on small datasets, anecdotal evidence, and assumptions. A long-term solution would be to overcome the mantra of publication metrics for evaluating scientists in academia. [ABSTRACT FROM AUTHOR]

Wastewater treatment in the paper industries is of paramount importance in terms of the concentration and type of pollutants as well as the quantity of water used in the production process. In this study, wastewater from a company in Tehran province was treated through two consecutive processes: electrocoagulation and electro-Fenton, in which the effluent of the electrocoagulation unit entered the electro-Fenton unit. After performing initial tests and setting the appropriate range of parameters affecting both processes, experiments were designed using Box Behnken Design. The objective was to reduce Total Suspended Solids and Chemical Oxygen Demand and optimize the variables influencing the performance of both processes. The impact of different factors, such as time, current, hydrogen peroxide concentration, and pH was investigated. Chemical Oxygen Demand and Total Suspended Solids removal of 55% and 96% were, respectively, achieved using EC conducted at pH 8.5, current of 1.049 A, and retention time of 32.4 min. The Chemical Oxygen Demand abatement efficiency of the electro-Fenton process was found as 66.2% within 46.2 min, hydrogen peroxide concentration of 1077 mg/L and current of 0.036 A. The initial Chemical Oxygen Demand of the untreated wastewater was 1080 mg/L, and after treatment, using the hybrid process it reached 175 mg/L. The result showed that the hybrid processes used less energy than single electrocoagulation or electro-Fenton. [ABSTRACT FROM AUTHOR]

An increasing fake paper problem is a cause for concern in the scientific community. These papers look scientific but contain manipulated data or are completely fictitious. So-called paper mills produce fake papers on a large scale and publish them in the name of people who buy authorship. The aim of this study was to learn more about the characteristics of fake papers at the metadata level. We also investigated whether some of these characteristics could be used to detect fake papers. For that purpose, we examined metadata of 12 fake papers that were retracted by Naunyn-Schmiedeberg's Archives of Pharmacology (NSAP) in recent years. We also compared many of these metadata with those of a reference group of 733 articles published by NSAP. It turned out that in many characteristics the fake papers we examined did not differ substantially from the other articles. It was only noticeable that the fake papers came almost exclusively from a certain country, used non-institutional email addresses more often than average, and referenced dubious literature significantly more often. However, these three features are only of limited use in identifying fake papers. We were also able to show that fake papers not only contaminate the scientific record while they are unidentified but also continue to do so even after retraction. Our results indicate that fake papers are well made and resemble honest papers even at the metadata level. Because they contaminate the scientific record in the long term and this cannot be fully contained even by their retraction, it is particularly important to identify them before publication. Further research on the topic of fake papers is therefore urgently needed. [ABSTRACT FROM AUTHOR]

Honesty of publications is fundamental in science. Unfortunately, science has an increasing fake paper problem with multiple cases having surfaced in recent years, even in renowned journals. There are companies, the so-called paper mills, which professionally fake research data and papers. However, there is no easy way to systematically identify these papers. Here, we show that scanning for exchanged authors in resubmissions is a simple approach to detect potential fake papers. We investigated 2056 withdrawn or rejected submissions to Naunyn–Schmiedeberg's Archives of Pharmacology (NSAP), 952 of which were subsequently published in other journals. In six cases, the stated authors of the final publications differed by more than two thirds from those named in the submission to NSAP. In four cases, they differed completely. Our results reveal that paper mills take advantage of the fact that journals are unaware of submissions to other journals. Consequently, papers can be submitted multiple times (even simultaneously), and authors can be replaced if they withdraw from their purchased authorship. We suggest that publishers collaborate with each other by sharing titles, authors, and abstracts of their submissions. Doing so would allow the detection of suspicious changes in the authorship of submitted and already published papers. Independently of such collaboration across publishers, every scientific journal can make an important contribution to the integrity of the scientific record by analyzing its own pool of withdrawn and rejected papers versus published papers according to the simple algorithm proposed in the present paper.

The paper mill crisis, which is polluting the scholarly literature with fake papers, has led to record-breaking article retractions and continues to erode trust in science. While publishers and other scholarly publishing stakeholders have mobilized to address this grave threat to research and publishing integrity, action from the library community has been lacking. This article explores the ongoing impact of the paper mill crisis and its causes. It also reviews the steps being taken across the sector to address it. This includes actions taken by publishers, integrity sleuths and organizations like Retraction Watch, NISO and STM. Based on the severity of the crisis and the current response, this article recommends actions libraries can take to help address the crisis and clean up the mess paper mills have made in the scholarly literature. At a time of declining trust and growing threats facing society, it is critical that all scholarly publishing stakeholders, including librarians, help hold the line on publishing integrity and restore trust in science.

Due to the high concentration of various contaminants in the paper mill effluent, it must undergo an efficient treatment process before being discharged to the environment or being reused in the production cycle. In the present study, the submerged membrane adsorption bioreactor (SMABR) system was used for the treatment of the paper mill effluent. The modified polyethersulfone PES/MoS2 membrane was fabricated by incorporating exfoliated MoS2 nanosheets prepared in the laboratory, into the PES matrix. This membrane along with the powdered activated carbon (PAC) were utilized in the SMABR system for the paper mill effluent treatment. After the acclimation of the sludge with the target effluent, the optimum values of food to microorganism (F/M), hydraulic retention time (HRT), and adsorbent dosage were determined separately to be 0.451, 18 h, and 3 g/L by considering the maximum values of chemical oxygen demand (COD) removal and mixed liquor suspended solid MLSS concentration in each stage. In the final stage, the MBR and SMABR systems (using the pristine and modified membranes, separately) were prepared to separately investigate the effect of the presence of the PAC adsorbent and modified membrane, on the output parameters. In all systems, the values of pH and dissolved oxygen (DO) were maintained in the normal range (pH: 6.2–6.7, DO>2) to provide favorable conditions for the growth of microorganisms. Most importantly, best performance in this study was related to the SMABR system consisting the PES/MoS2 membrane and PAC adsorbent, with the highest values of COD removal (96%), MLSS concentration (15620 mg/L), and membrane permeation flux (110 L/m2.h). It is worth mentioning that the functionalized membrane exhibited better hydrophilicity compared with the pristine membrane, resulting in high water permeation flux, which is in accordance with the performance results.

The experiment was conducted near a paper mill industry to evaluate the influence of combining treated wastewater and sludge from paper mills on soil quality and productivity of Ragi (Eleusine coracana) also known as finger millet. The study examined soil microbiota, soil enzymes, and yield characteristics of Ragi across different treatments. Among the treatments, the application of effluent treatment plant (ETP) sludge vermicompost at 5 t ha-1 with drip irrigation using treated effluent (T8) resulted in a notable increase in bacterial, fungal and actinomycetes populations (29.49 × 106, 15.50 × 104 and 9.75 × 10² colony-forming units (CFU) ml-1, respectively) at harvest stage. Enzymatic activities in the post-harvest soil, including amylase and invertase (0.99 and 1.49 mg reducing sugars g-1 soil 24 h-1, respectively), cellulose (38.50 µg reducing sugars g-1 soil 24 h-1), phosphatase (18.93 µg phenols g-1 soil 24 h-1) and dehydrogenase (48.19 µg triphenyl formazan g-1 soil 24 h-1) were also significantly higher in the T8 treatment. Plant height, number of tillers, grain and straw yields were all notably higher in T8. The addition of vermicompost sludge enhanced soil microbial activity, thereby stimulating soil enzyme production. As a result, applying ETP sludge vermicompost at 5 t ha-1, along with treated effluent through drip irrigation, significantly enhanced soil health and ragi yield. [ABSTRACT FROM AUTHOR]

The present study investigated the phycoremediation efficacy of two freshwater green microalgae Chlorella ellipsoidea and Desmodesmus opoliensis for treatment of water of Ellenga beel, a wetland located in the vicinity of Nagaon paper mill and into which effluents of the paper mill are drained-off. After inoculation of water samples with the two freshwater green microalgae, the culture medium were analyzed for various physicochemical parameters such as pH, electrical conductivity, total dissolved solids, phosphate, nitrate, potassium, chloride, phenol, cyanide, biological oxygen demand, chemical oxygen demand and heavy metals at every seven days interval for a period of 42 days. A reduction of phosphate (85%), sulfate (96%), nitrate (76%) and chloride (48%) was observed after 42 days of incubation in the tested beel water. The micro algal incubation also resulted in decrease of heavy metal such as Pb (54%), Zn (98%), Cr (59%), and Cu (61%). Comparison of Fourier transform infrared spectra of beel water samples (control) with those inoculated with the test micro algal species showed presence of binding sites for certain functional groups like phosphate, amide, carbohydrate and alkyl halides in inoculated samples. D. opoliensis exhibited higher phycoremediation efficiency than C. ellipsoidea in removal of pollutants from the beel water samples. [ABSTRACT FROM AUTHOR]

This article analyses the importance of paper in the context of early modern warfare. During the war against the Ottoman Empire at the end of the 17th century, the Habsburgs were establishing a new administration in Hungary, which served both military and civil purposes. Not only did administrative tasks have to be organized, but the very success of military operations depended on the well-ordered work of the administration: communication had to be smooth, and a wide variety of tasks had to be properly and reliably processed. To fulfil these requirements, the administration needed large quantities of paper. This study follows the traces of paper in the records of the Chamber Administration in Buda and points to the vital need for paper at the heart of the new Habsburg rule. The challenges of acquiring and producing paper themselves became crucial aspects of the administration’s work. The article argues that a reliable supply of paper competed even with the distribution of arms and food to become an essential resource in warfare. [ABSTRACT FROM AUTHOR]

At a paper manufacturing mill (PML) that had been previously part of an integrated pulp (bisulphite) and paper mills industry, cyanobacterial blooms were observed in the mill's aerated stabilization basin (ASB) ponds at about 3 years after pulping had been discontinued. This study aimed to determine the factors that led to bloom occurrences and potential control strategies applicable to the paper manufacturing mill's, aerated stabilization basin system that discharges wastewaters into a coastal lake. Following discontinuation of pulping, the colour of the wastewaters reduced to low levels (~ 10 Hazen units or less), while the levels of nutrient remained potentially supportive of cyanobacteria growth with total phosphorus at ~ 0.1 mg/L and total nitrogen at > 2.5 mg/L. Incidences of blooms in the ABS were associated with preceding average monthly rainfalls and wind speeds being less (~ 44% and ~ 7%, respectively) and average direct sunlight hours being greater (~ 9%) than the long-term average values. Zinc was investigated for control of cyanobacteria as this metal is less toxic to aquatic organisms and microflora than copper algaecides. In laboratory culture trials, zinc was found to inhibit growth of M. aeruginosa (strain MIC338) and Pseudanabaena sp. when dosed at ~ 2.5 mg/L. The inhibition of cyanobacteria by zinc was found to vary between ASB pond samples which had different in situ chlorophyll a levels. This study found that the PML wastewaters investigated can be supportive of cyanobacterial growth to bloom levels after discontinuation of pulping processes and that zinc has potential as a cyanobacteria control agent.

Industrial processes and municipal wastes largely contribute to the fluctuations in iron (Fe) content in soils. Fe, when present in unfavorable amount, causes harmful effects on human, flora, and fauna. The present study is an attempt to evaluate the composition of Fe in surface soils from paper mill and municipal landfill sites and assess their potential ecological and human health risks. Geochemical fractionation was conducted to explore the chemical bonding of Fe across different fractions, i.e., water-soluble (F1) to residual (F6). Different contamination factors and pollution indices were evaluated to comprehend Fe contamination extent across the study area. Results indicated the preference for less mobile forms in the paper mill and landfill, with 26.66% and 43.46% of Fe associated with the Fe–Mn oxide bound fraction (F4), and 57.22% and 24.78% in the residual fraction (F6). Maximum mobility factor (MF) of 30.65% was observed in the paper mill, and 80.37% in the landfill. The enrichment factor (EF) varied within the range of 20 < EF < 40, signifying a high level of enrichment in the soil. The individual contamination factor (ICF) ranged from 0 to >6, highlighting low to high contamination. Adults were found to be more vulnerable towards Fe associated health risks compared to children. The Hazard Quotient (HQ) index showed the highest risk potential pathways as dermal contact > ingestion > inhalation. The study offers insights into potential Fe contamination risks in comparable environments, underscoring the crucial role of thorough soil assessments in shaping land use and waste management policies. [Display omitted] • Geochemical fractionation unveils less bioavailable Fe in contaminated soil. • EF, ICF, and I geo indicate high Fe contamination. • Adults are more susceptible to potential health risks from surplus Fe exposure. • HQ analysis pinpoints dermal contact as the primary pathway for Fe exposure risks.

Due to the huge amounts of wastewater discharge and the high pollution loads in papermaking industry, many greenhouse gases (GHG) are emitted in the papermaking wastewater treatment process. The wastewater dissolved oxygen (DO) control has been considered as the most cost-effective control solution for GHG reduction in wastewater treatment plants (WWTP). However, the competition between contaminant removal efficiency and GHG reduction hinders the drastic reduction of GHG emissions from WWTP. In this study, based on the established integrated GHG emission model, explicitly considering the total GHG reduction targets on the premise of effluent compliance, an intelligent control scheme has been developed for an activated sludge process in a paper mill. Regarding DO as the controlled variable, the proposed hierarchical optimal proportional-integral (HOPI) control scheme was established consisting of three layers: 1) Layer 1 for the effluent quality estimation, 2) Layer 2 for the optimal DO set point determined by genetic algorithm with the influent variations to obey discharging norms and reduce GHG emissions, 3) Layer 3 for the DO tracking proportional integral (PI) control with the controller parameters adjusted by the back propagation neural network to track the dynamically optimized DO set points. The simulation results showed that, compared with the open-loop (OL) operation (averaged aeration, 10/h), the proposed HOPI control (averaged aeration, 7.9/h) reduced the GHG emissions by 12.54% under the premise of discharging norms, which was mainly attributed to the reduction of the aeration electricity consumption. In contrast, the PI control (averaged aeration, 12.9/h) increased the GHG emissions by 7.48% compared with the OL operation. Thus, the proposed HOPI control strategy has demonstrated potential for the application of GHG reduction in industrial WWTPs. [ABSTRACT FROM AUTHOR]

Slime deposition on paper is a major problem confronted in paper-mills resulting in spoiled quality of the final product and huge economic losses. Conventional methods use chemical biocides for slime eradication which lead to effluent toxicity. Eco-friendly compounds can be used as alternatives for inhibition of biofilm/slime formation by bacteria. Autoinducer-2 (AI-2) based quorum sensing (QS) is a universal communication mechanism present in bacteria. In this study, bacteria isolated from paper-mill slime samples were identified for biofilm forming potential and AI-2 activity. Natural and synthetic compounds from PubChem library were selected by docking with AI-2 producer-LuxS, and were tested for inhibition of biofilm formation by the consortium of all paper-mill bacterial isolates. Triclosan was found to be the best as it reduced the expression of luxS and inhibited biofilm formation, as shown by Field Emission Scanning Electron Microscope (FE-SEM), to 50% at a concentration of 23.43 μg/ml and acted as biocide at 30 μg/ml for complete inhibition of growth when tested in the Research and development (R and D) set-up of paper mill. The pleiotropic inhibition of bacterial communities in paper mills by triclosan at environmentally safe concentrations can therefore stop slime formation and paper deterioration in an eco-friendly way and can prevent economic losses. • Thermophilic bacteria from paper-mill formed biofilm and showed AI-2 quorum sensing. • Triclosan docked molecularly with AI-2 producer (LuxS) and inhibited its expression. • Commercial grade triclosan inhibited bacterial consortium biofilm/slime formation. • Triclosan acted as biocide at 30 μg/ml in R and D set-up of paper mill.
