Authors: Aminova A F , Yarmuhametova G U , Mazitova A K 
Published: December 2019

Abstract
In the study the authors constructed mathematical models of wastewater treatment processes with Fenton’s reagent, ozone oxidative purification in the presence of a homogeneous catalyst, ozone oxidative purification in the presence of a heterogeneous catalyst, ozone oxidative purification in the presence of hydrogen peroxide — the Peroxon process. The resulting mathematical models allow the authors to predict the rate of chemical oxygen consumption (COD) at any time during the cleaning process, as well as to plan time expenditures to achieve the required level of this indicator. In addition, in the course of the research the integral coefficient of the models was calculated as a function of time, allowing to compare the cleaning processes and rank them by efficiency. As a result of the analysis of the integral coefficient, it was shown that the most effective is the oxidative purification of waste water with ozone in the presence of a homogeneous catalyst.

Published: December 2019

Abstract
The purpose of the study was to determine denitrification rates during aeration tanks converting to the aero-mode of the nitri-denitrifier with the nitrate recycling. Studies were conducted on an experimental facility with wastewater and activated sludge from one of the sewage treatment facilities of the Udmurt Republic. At the beginning of the experiment, the activated sludge was under anoxic conditions (the mixture was mechanically mixed without aeration), while periodically the mixture was analyzed for nitrate content. Thus, the rate of denitrification during endogenous respiration was determined. Further, waste water was added to the sludge (anoxic conditions were preserved) - simulation of nitrate recycling. According to the results of experimental studies, the calculated denitrification rates were rds
= 0.71 ± 0.04 mg N-NO3
/ mg of active heterotrophic microorganisms per day on easily oxidizable substrate, on endogenous respiration rde
= 0.12 ± 0.02 mg N-NO3
/ mg of active heterotrophic microorganisms per day, on difficult oxidizable substrate rdp
= 0.12 ± 0.01 mg N-NO3
/ mg of active heterotrophic microorganisms per day.
Purification of wastewater of some construction materials production
Authors: Mazitova A K , Aminova A F , Sukhareva I A 
Published: December 2019

Abstract
The wastewater of the wood-based industry contains toxic phenols that exceed the maximum allowable values. There is little data on the methods of purification of wastewater of woodworking plants from aromatic compounds and their derivatives in the literature. Therefore, the authors investigated the different effect of ozone on the wastewater of the Ufa plywood-slab plant for the purpose of purification. The flocculating effect of ozone and the physicochemical method (coagulation and flocculation) of wastewater treatment were investigated. The use of ozone in the first stage of wastewater treatment allows reducing the concentration of suspended substances to the required level with the help of an environmentally friendly method and preparing wastewater for oxidative purification from toxic substances. The suggested method is not only more environmentally acceptable, but also more economically reasonable, because reagent acquisition costs are excluded.

Published: December 2019

Abstract
The article is devoted to the issue of improving the environmental safety of the construction industry by improving dust collectors of dust removal systems using additive-complex dispersive analysis of variance of dust emissions by aspiration systems. The article proposes the improvement of complex analysis of variance using hydrodynamic criteria in output functions. Modified output data and additive-simplex approach to the evaluation of characteristics - equivalent sizes and speeds of sedimentation-soiling of dust particles make it possible to determine the ranges of their changes with a higher degree of accuracy of the results. The distributions of the hydrodynamics criteria values allow us to obtain reliable meanings for sedimentation velocities and equivalent particle’s sizes for the studied dust samples of building materials. Analytical approach to determining the density distribution of the numerical values of the criteria allowed clarifying the values of sedimentation-soiling velocities and hydraulic equivalent sizes of particles to get more reliable of their changes ranges. The authors present the most essential regressions and mark to method determining hydraulic work regimes for design dust collectors. This approach is one of the most effective ways to improve the environmental safety of the construction industry.

Published: December 2019

Abstract
The article presents the thermodynamic substantiation of the necessary and sufficient basicity of calcium aluminates for the formation of the preferred form of ettringite during purification of mine water from sulfate ions, the selection results based on the data obtained and studying the phase composition of aluminothermic slags by X-ray phase analysis of the preferred precipitating reagent. It has been established that mainly basic calcium aluminates are present in the chromium metal production slags, while ferrotitanium and ferrochrome production slags contain up to 35% majenite - 12CaO 7Al2O3, the presence of which in the precipitator increases the feasibility of precipitation from ettringite in the form of calcium mono-hydrosulfoaluminates. The results of the experimental verification of the feasibility and effectiveness of the purification of the model sub-waste water are presented. It is shown that it is possible in principle to reduce sulfates to MAC in mine waters using two-stage sedimentation using ferrotitanium production after liming as a reagent-precipitant of mechanically activated slag.
Probiotics as one of methods for dairy wastewaters’ treatment intensification
Authors: Glushchenko E S , Vialkova E I , Sidorenko O V 
Published: December 2019

Abstract
Despite the rapid production growth, creation of new technologies improving production quality, the problem of increasing amounts of wastewaters with specific composition and qualities has not solved yet. Wastewaters formed at dairy plants have high concentrations of some contaminations. Qualitative indices of these wastewaters, such as pH, COD, anionic surfactants, nitrogen and phosphorus compounds, differ dramatically from domestic wastewaters’ ones. Wastes and product residuals, dumped into sewage system, aggravate this situation. Nowadays, many plants do not have any local treatment plants, which can cope with polluted effluents, while existing ones cannot provide with required degree of wastewater treatment. This article presents the research of probiotics’ influence on the qualitative composition of dairy wastewaters using Belgian probiotic “Pip Plus WATER”. Besides, based on the experimental research results, a technological scheme of local treatment plant that can be realized at dairy plants is proposed.
A systematic review of the evidence for the efficacy of opioids for chronic non-cancer pain in community-dwelling older adults
Authors: O’Brien Michael David Cory , Wand Anne Pamela Frances 
Published: December 2019

Abstract

Introduction
the ageing global population and concomitant increase in the use of opioid analgesia have highlighted the need to evaluate the effectiveness of opioids for chronic pain in older people.

Methods
a systematic review of the evidence for the efficacy of opioids for chronic non-cancer pain in community-dwelling people aged 65 years or more was conducted using PRISMA guidelines. The databases MEDLINE, EMBASE, Pubmed and PsychINFO were searched. The quality of studies was assessed. Secondary aims were to assess correlates of opioid use and the decision-making processes of prescribers.

Results
seven studies were identified of low to high quality. The majority of older people experienced ongoing pain despite continuing opioid therapy. There were mixed results regarding benefits of opioids in terms of activities of daily living and social engagement. In nursing home residents, opioid use at baseline was associated with severe pain, severe impairment in activities of daily living and a diagnosis of depression. Fear of causing harm to older people was common amongst opioid prescribers, limiting prescription. Facilitators of opioid prescription included educational interventions and access to an evidence base for opioid use.

Conclusion
there is limited evidence supporting the use of long-term opioid use in older people for chronic non-cancer pain and a lack of trials in this age group. Age-specific guidelines are required addressing initial assessment, indications, monitoring and de-prescribing.
Plasticity in the growth habit prolongs survival at no physiological cost in a monocarpic perennial at high altitudes
Authors: Cotado Alba , Munné-Bosch Sergi 
Published: December 2019

Abstract

Background and Aims
Monocarpic plants are those that flower, produce seeds and then die. Although most monocarpic plants are annual or biennial, some of them are perennial. However, relatively little is known regarding the biology of monocarpic perennials. Pyrenean saxifrage (Saxifraga longifolia) is a monocarpic perennial that is well adapted to high-mountain ecosystems. Here, we evaluated altitudinal changes in clonality in various populations growing in their natural habitat with particular emphasis on the physiological costs of clonal growth.

Methods
We assessed the percentage of clonal plants in nine populations growing in their natural habitat, as well as the plant stress response of clonal and non-clonal plants, in terms of photoprotection and accumulation of stress-related phytohormones, in a 3-year study at Las Blancas (2100 m a.s.l.). We also evaluated the influence of plant size on the activation of defensive responses to biotic and abiotic stresses.

Key Results
We found that 12 % of Pyrenean saxifrage plants growing at the highest altitudes (2100 m a.s.l.) produced lateral rosettes which survived the flowering of the main rosette and shared the same axonomorphic root, thus escaping monocarpic senescence. This clonal growth did not worsen the physiological performance of plants growing at this altitude. Furthermore, increased plant size did not negatively affect the physiology of plants, despite adjustments in endogenous stress-related phytohormones. In contrast, maturity led to rapid physiological deterioration of the rosette, which was associated with monocarpic senescence.

Conclusions
This study shows that the evolution of clonality has allowed Pyrenean saxifrage to survive harsh environmental conditions and it provides evidence that harsh environments push plant species to their limits in terms of life form and longevity.

Published: December 2019

Abstract
As an important post-translational modification (PTM), protein phosphorylation is involved in the regulation of almost all of biological processes in eukaryotes. Due to the rapid progress in mass spectrometry-based phosphoproteomics, a large number of phosphorylation sites (p-sites) have been characterized but remain to be curated. Here, we briefly summarized the current progresses in the development of data resources for the collection, curation, integration and annotation of p-sites in eukaryotic proteins. Also, we designed the eukaryotic phosphorylation site database (EPSD), which contained 1 616 804 experimentally identified p-sites in 209 326 phosphoproteins from 68 eukaryotic species. In EPSD, we not only collected 1 451 629 newly identified p-sites from high-throughput (HTP) phosphoproteomic studies, but also integrated known p-sites from 13 additional databases. Moreover, we carefully annotated the phosphoproteins and p-sites of eight model organisms by integrating the knowledge from 100 additional resources that covered 15 aspects, including phosphorylation regulator, genetic variation and mutation, functional annotation, structural annotation, physicochemical property, functional domain, disease-associated information, protein-protein interaction, drug-target relation, orthologous information, biological pathway, transcriptional regulator, mRNA expression, protein expression/proteomics and subcellular localization. We anticipate that the EPSD can serve as a useful resource for further analysis of eukaryotic phosphorylation. With a data volume of 14.1 GB, EPSD is free for all users at http://epsd.biocuckoo.cn/.

Published: December 2019

Abstract
Mood-congruent memory bias is a critical characteristic of depression, but the underlying neural mechanism is largely unknown. Negative memory schemas might enhance encoding and consolidation of negative experiences, thereby contributing to the genesis and perpetuation of depressive pathology. To investigate this relationship, we aimed to perturb medial prefrontal cortex (mPFC) processing, using neuronavigated transcranial magnetic stimulation (TMS) targeting the mPFC. Forty healthy volunteers first underwent a negative mood induction to activate negative schema processing after which they received either active inhibitory (N = 20) or control (N = 20) stimulation to the mPFC. Then, all participants performed the encoding of an emotional false memory task. Recall and recognition performance was tested the following morning. Polysomnographic data were recorded continuously during the night before and after encoding. We observed a significantly lower false recognition of negative critical lures following mPFC inhibition, but no differences in veridical memory. These findings were supported by reaction time data, showing a relative slower response to negative compared with positive critical lures. The current findings support previous causal evidence for a role of the mPFC in schema memory processing and further suggest a role of the mPFC in memory bias.
Penetration of Digital Payments in Greece after Capital Controls: Determinants and Impact on VAT Revenues
Authors: Danchev Svetoslav , Gatopoulos Georgios , Vettas Nikolaos 
Published: December 2019

Abstract
The use of payment cards in Greece more than tripled in value between 2014 and 2017. Their penetration lifted off with the imposition of capital controls in 2015 and then remained on an uptrend, aided further by the measures of law 4446/2016. According to the findings of the study: (i) the law had a statistically significant, positive impact on card usage, especially in the second half of 2017, controlling for the effects of macroeconomic factors and capital controls and (ii) the penetration of electronic payments had a significant positive impact on tax compliance. Nevertheless, the average level of card use in Greece has remained lower than the EU average, while it presents significant heterogeneity across sectors and geographical areas. In conclusion, more targeted measures are warranted in order to enhance further the penetration of electronic payments, which would yield even greater fiscal benefits.

Abstract
Knowing the causes of biological invasion success can be relevant to combat future invasive processes. The recent invasion of the horseshoe whip snake Hemorrhois hippocrepis on the island of Ibiza provides the opportunity to compare natural history traits between invasive and source populations, and to unravel what makes this snake a successful invader that is threatening the only endemic vertebrate of the island, Podarcis pityusensis. This study compares the basic reproductive traits of mainland native and invasive populations of the snake. Our results revealed that invasive populations were characterized by female maturity at a smaller size, extended reproductive period, and much lower reproduction frequency compared to the native population. In contrast, some major reproductive traits—the abdominal fat body cycle, clutch size, hatchling body size, and hatchling body condition, did not differ between the two populations. Some of these results must reflect the environmental differences in the recently invaded island with respect to the source area, and overall plasticity of reproductive traits. Plasticity is evolutionarily interesting, and may aid the successful growth of this species in their invasiveness of Mediterranean islands like Ibiza. The most significant finding is that this expression of phenotypic plasticity occurred rapidly in this invasive population, within a period of 14 years maximum. Our results on the reproduction ecology of the invasive population were not conclusive regarding the factors determining the invasiveness of the snake and pointed to alternative causes.
Morphological determinants of jumping performance in the Iberian green frog
Authors: Moreno-Rueda Gregorio , Requena-Blanco Abelardo , Zamora-Camacho Francisco J , Comas Mar , Pascual Guillem 
Published: December 2019

AbstractPredation is one of the main selective forces in nature, frequently selecting potential prey for developing escape strategies. Escape ability is typically influenced by several morphological parameters, such as morphology of the locomotor appendices, muscular capacity, body mass, or fluctuating asymmetry, and may differ between sexes and age classes. In this study, we tested the relationship among these variables and jumping performance in 712 Iberian green frogs Pelophylax perezi from an urban population. The results suggest that the main determinant of jumping capacity was body size (explaining 48% of variance). Larger frogs jumped farther, but jumping performance reached an asymptote for the largest frogs. Once controlled by structural body size, the heaviest frogs jumped shorter distances, suggesting a trade-off between fat storage and jumping performance. Relative hind limb length also determined a small but significant percentage of variance (2.4%) in jumping performance—that is, the longer the hind limbs, the greater the jumping capacity. Juveniles had relatively shorter and less muscular hind limbs than adults (for a given body size), and their jumping performance was poorer. In our study population, the hind limbs of the frogs were very symmetrical, and we found no effect of fluctuating asymmetry on jumping performance. Therefore, our study provides evidence that jumping performance in frogs is not only affected by body size, but also by body mass and hind limb length, and differ between age classes.
Postharvest Burial of Drosophila suzukii (Diptera: Drosophilidae) Infested Fruit Waste Reduces Adult Emergence
Authors: Hooper Holly , Grieshop Matthew J 
Published: December 2019

Abstract
The arrival of spotted wing Drosophila, Drosophila suzukii (Matsumura), to the United States has caused many berry and cherry growers to replace IPM programs with calendar-based broad-spectrum insecticide programs. Alternative management tactics are urgently needed to mitigate the current dependency on chemical control. Postharvest burial is a cultural crop sanitation strategy that has the potential to reduce D. suzukii reproductive habitat and eliminate infested fruit wastes. This study revealed that D. suzukii rarely pupate on the soil’s surface or below 1 cm, but are capable of unburying themselves from depths up to 48 cm. Although zero emergence was not obtained in the field, adult emergence decreased exponentially with deeper burial depths. A burial depth of 24 cm reduced D. suzukii emergence by 97%, although soil texture may influence this optimal burial depth. Soils that had a higher concentration of sand had a negative impact on D. suzukii survival at shallower burial depths. The mechanism behind the reduction in adult emergence from differing burial depths remains unclear as the lipid concentration between emerging D. suzukii was the same regardless of burial depth.
Aortic valve endocarditis with root abscess causing superior vena cava obstruction: a case report
Authors: Scullion Malo Marcel Francois , Lynn Peter , Marshall Adam , MacDougall David 
Published: December 2019

Abstract

Background
To our knowledge, we report the first case of endocarditis with root abscess causing compressive superior vena cava (SVC) obstruction.

Case summary
An 84-year-old gentleman with previous tissue aortic valve replacement presented with fevers and systemic upset. Blood cultures grew Streptococcus anginosus and transoesophageal echocardiogram identified prosthetic valve vegetations with an associated root abscess. Antibiotics were commenced and referral made for surgical consideration. Several days into treatment the patient developed clinical signs of SVC obstruction and computed tomography demonstrated an enlarging root abscess with SVC compression. The patient was discussed with local cardiothoracic centres, but surgery was not an option primarily due to abscess size and vascular involvement. Priority moved from active to palliative treatment given no improvement with antibiotics, unsuitability for surgery, and patient discomfort. Within several weeks, symptoms/signs of SVC obstruction actually improved, likely due to collateral venous circulation formation and the patient was discharged home with palliative care input.

Discussion
There are previous reports of SVC obstruction related to infected SVC thrombus, indwelling intravascular devices, and para-aortic abscess, but none related to infective endocarditis. Streptococcus anginosus endocarditis is rare but often associated with abscess formation, and male gender, increasing age, and previous surgery are recognized risk factors.
