Authors: Monteiro Daiane da Rosa , Báo Ana Cristina Pretto , Souza Tabata de Cavatá , Tanaka Raquel Yurika
Published: October 2020

A lesão por pressão se caracteriza por um dano na pele resultante de uma pressão intense ou prolongada. O Brasil apresenta altas taxas de incidência de lesão por pressão em pacientes internados, o que torna a terapia a laser uma alternativa de tratamento adjuvante para a reparação tecidual. O presente estudo teve como objetivo analisar a efetividade da terapia a laser de baixa potência no tratamento de lesões por pressão em pacientes adultos. Trata-se de uma revisão integrativa com oito artigos selecionados nas bases de dados Lilacs, Pubmed e Medline entre o período de 2010 e 2020. Após a leitura, análise e interpretação dos dados, pode-se verificar que, apesar de haver poucos estudos recentes sobre a terapia a laser na temática da lesão por pressão, os artigos elucidam o uso do laser como uma modalidade promissora de tratamento, que proporciona redução do tempo de cicatrização e melhora no aspecto das feridas. Contudo, os estudos apresentam distintos parâmetros de aplicação, comprimentos de onda, densidade de energia e frequência de tratamento, o que impossibilita um consenso entre os autores sobre a técnica de aplicação do laser. Há a necessidade de novas pesquisas para criar e elucidar padronizações ou protocolos, a fim de otimizar a qualidade de atendimento aos pacientes portadores de lesão por pressão e promover a divulgação da terapia a laser como um tratamento seguro e efetivo.

As instituições da Rede Federal de Educação Profissional, Científica e Tecnológica (RFEPCT) desde 1909, tem assumido, prioritariamente, o compromisso transformador na sociedade ao formar os cidadãos humildes em trabalhadores qualificados por meio da educação profissional. Considerando a manutenção de tal preceito na RFEPCT, questiona-se, então, se o Instituto Federal de Mato Grosso (IFMT) acolhe, de fato, os jovens pertencentes às famílias de baixa renda e centra a oferta do ensino profissional e o desenvolvimento de suas atividades nesse público-alvo. Este artigo tem como objetivo analisar a renda per capita familiar dos alunos do IFMT comparando-os aos dados de Índice de Desenvolvimento Humano (IDH) e do Produto Interno Bruto (PIB) per capita dos municípios sedes dos 14 campi e 05 campi avançados. Os procedimentos metodológicos adotados para o alcance deste intento foram a pesquisa bibliográfica e documental, por meio de levantamento de fontes institucionais oficiais e banco de dados do IBGE. Os resultados apontaram que, no ano de 2016, a instituição atendeu 64,5% de alunos pertencentes a família de baixa renda, com uma renda per capita familiar inferior a 1,5 salário-mínimo. A partir desse período, adotou as políticas de inclusão/acesso/permanência, por meio da institucionalização do sistema de cotas, destinando 60% de suas vagas para alunos advindos de escolas públicas e, dentre essas, para pessoas com deficiência e autodeclarados pardos, pretos e índios. Assim, tem buscado promover a inserção social de jovens de baixa renda e contribuir para o crescimento e desenvolvimento de regiões do estado de Mato Grosso.

Published: October 2020

The pathogenic dental biofilm formed by species presents itself as a serious problem, since it contributes to the development of oral and bodily diseases. In this sense, Dentistry stands out for expanding knowledge about the oral ecosystem and performing procedures aimed at reducing its pathogenicity and improving oral health. Thus, technological advances and indiscriminate application of antibiotics have made bacterial strains resistant, with a great search for safer, more natural and effective methods. Therefore, the use of plants for healthy treatments is an area of great study in Dentistry. In the present literature review, we sought to analyze the species Zingiber officinali with its antimicrobial and antibiofilm activity. For this study, materials were searched at the BIREME, CINAHL, Cochrane Library, Embase, Google Schoolar, PubMed, Science Direct, published until August 2020. The search for the articles was carried out in August 2020, of the 3,401 studies were refined in 18. The findings showed that the plant Zingiber officinale has the capacity to inhibit certain bacteria in vitro, such as Bacillus sp., Escherichia coli, Pseudomonas aeruginosa, Streptococcus mutans and fungi, like Candida albicans. Thus, studies in the area are still needed in order to prove its effectiveness in vivo, to analyze the toxicity, drug interactions and side effects of the plant.

The aim of this study was to assess the effect of selected biostimulators and foliar fertilizers on plant development, plant yield, soil fertility and soil biochemical activity (dehydrogenases, phosphatases, catalases) during the cultivation of pea (Pisum sativum L.). A field experiment was conducted between 2016 and 2018 at the Gorzyń Experimental and Educational Station, Poznań University of Life Sciences in Poland. The following treatments were tested: (1) control; (2) Titanit; (3) Optysil; (4) Metalosate potassium; (5) Rooter; (6) Bolero Mo; (7) Adob Zn IDHA; (8) Adob B and (9) Adob 2.0 Mo. Adob Zn IDHA stimulated yields, especially under average moisture conditions and less so in drought conditions, and the differences compared to control amounted 8.36 and 4.3%, respectively. The results showed a close relationship between the effects of the biostimulators and foliar fertilizers and weather conditions during the study. It was not possible to determine whether any of the biostimulators or foliar fertilizers had a positive effect on pea seed yield in any year. Similarly, it was difficult to clearly determine the effect of the biostimulators and fertilizers on biochemical activity in the soil, although soil enzyme activity was influenced most by application of the Bolero Mo fertilizer. In all study years, biological nitrogen fixation was always greater after the application of a biostimulator/fertilizer treatment.
Structure, Function, and Therapeutic Use of IgM Antibodies

Published: October 2020

Natural immunoglobulin M (IgM) antibodies are pentameric or hexameric macro-immunoglobulins and have been highly conserved during evolution. IgMs are initially expressed during B cell ontogeny and are the first antibodies secreted following exposure to foreign antigens. The IgM multimer has either 10 (pentamer) or 12 (hexamer) antigen binding domains consisting of paired µ heavy chains with four constant domains, each with a single variable domain, paired with a corresponding light chain. Although the antigen binding affinities of natural IgM antibodies are typically lower than IgG, their polyvalency allows for high avidity binding and efficient engagement of complement to induce complement-dependent cell lysis. The high avidity of IgM antibodies renders them particularly efficient at binding antigens present at low levels, and non-protein antigens, for example, carbohydrates or lipids present on microbial surfaces. Pentameric IgM antibodies also contain a joining (J) chain that stabilizes the pentameric structure and enables binding to several receptors. One such receptor, the polymeric immunoglobulin receptor (pIgR), is responsible for transcytosis from the vasculature to the mucosal surfaces of the lung and gastrointestinal tract. Several naturally occurring IgM antibodies have been explored as therapeutics in clinical trials, and a new class of molecules, engineered IgM antibodies with enhanced binding and/or additional functional properties are being evaluated in humans. Here, we review the considerable progress that has been made regarding the understanding of biology, structure, function, manufacturing, and therapeutic potential of IgM antibodies since their discovery more than 80 years ago.
A Framework for Enhancing Big Data Integration in Biological Domain Using Distributed Processing

Published: October 2020

Massive heterogeneous big data residing at different sites with various types and formats need to be integrated into a single unified view before starting data mining processes. Furthermore, in most of applications and research, a single big data source is not enough to complete the analysis and achieve goals. Unfortunately, there is no general or standardized integration process; the nature of an integration process depends on the data type, domain, and integration purpose. Based on these parameters, we proposed, implemented, and tested a big data integration framework that integrates big data in the biology domain, based on the domain ontology and using distributed processing. The integration resulted in the same result as that obtained from the local integration. The results are equivalent in terms of the ontology size before the integration; in the number of added items, skipped items, and overlapped items; in the ontology size after the integration; and in the number of edges, vertices, and roots. The results also do not violate any logical consistency rules, passing all the logical consistency tests, such as Jena Ontology API, HermiT, and Pellet reasoners. The integration result is a new big data source that combines big data from several critical sources in the biology domain and transforms it into one unified format to help researchers and specialists use it for further research and analysis.

Published: October 2020

In this study, we aimed to determine the ammonia emission characteristics through analysis of ammonia concentration, ventilation rate, temperature, and relative humidity pattern in a mechanically ventilated swine finishing facility in Korea. Three pig rooms with similar environmental conditions were selected for repeated experimentation (Rooms A–C). Ammonia concentrations were measured using a photoacoustic gas monitor, and ventilation volume was estimated by applying the least error statistical model to supplement the missing data after measurement at several operation rates using a wind tunnel-based method. The mean ammonia concentrations were 4.19 ppm, and the ventilation rates were 24.9 m3 h−1 pig−1. Ammonia emissions were calculated within the range of 0.40–5.01, 0.25–4.16, and 0.37–5.68 g d−1 pig−1 for Room A, Room B, and Room C, respectively. Ammonia concentration and ventilation rate showed a weak negative correlation (r = −0.13). Ammonia emissions were more markedly affected by ammonia concentration (r = 0.88) than ventilation rate (r = 0.31). This indicates that ammonia concentration reduction can be effective in reducing ammonia emissions. The mean daily ammonia emissions, which increased exponentially over the finishing periods, were calculated as 1.78, 1.57, and 1.70 g d−1 pig−1 for Room A, Room B, and Room C, respectively (average 1.68 g d−1 pig−1).
A Review and Evaluation of Planetary Boundary Layer Parameterizations in Hurricane Weather Research and Forecasting Model Using Idealized Simulations and Observations

Published: October 2020

This paper reviews the evolution of planetary boundary layer (PBL) parameterization schemes that have been used in the operational version of the Hurricane Weather Research and Forecasting (HWRF) model since 2011. Idealized simulations are then used to evaluate the effects of different PBL schemes on hurricane structure and intensity. The original Global Forecast System (GFS) PBL scheme in the 2011 version of HWRF produces the weakest storm, while a modified GFS scheme using a wind-speed dependent parameterization of vertical eddy diffusivity (Km) produces the strongest storm. The subsequent version of the hybrid eddy diffusivity and mass flux scheme (EDMF) used in HWRF also produces a strong storm, similar to the version using the wind-speed dependent Km. Both the intensity change rate and maximum intensity of the simulated storms vary with different PBL schemes, mainly due to differences in the parameterization of Km. The smaller the Km in the PBL scheme, the faster a storm tends to intensify. Differences in hurricane PBL height, convergence, inflow angle, warm-core structure, distribution of deep convection, and agradient force in these simulations are also examined. Compared to dropsonde and Doppler radar composites, improvements in the kinematic structure are found in simulations using the wind-speed dependent Km and modified EDMF schemes relative to those with earlier versions of the PBL schemes in HWRF. However, the upper boundary layer in all simulations is much cooler and drier than that in dropsonde observations. This model deficiency needs to be considered and corrected in future model physics upgrades.

Authors: Makhoul Karim , Ahdab Rechdi , Riachi Naji , Chalah Moussa , Ayache Samar
Published: October 2020

Tremor is an important and common symptom in patients with multiple sclerosis (MS). It constituted one of the three core features of MS triad described by Charcot in the last century. Tremor could have a drastic impact on patients’ quality of life. This paper provides an overview of tremor in MS and future perspectives with a particular emphasis on its epidemiology (prevalence: 25–58%), clinical characteristics (i.e., large amplitude 2.5–7 Hz predominantly postural or intention tremor vs. exaggerated physiological tremor vs. pseudo-rhythmic activity arising from cerebellar dysfunction vs. psychogenic tremor), pathophysiological mechanisms (potential implication of cerebellum, cerebello-thalamo-cortical pathways, basal ganglia, and brainstem), assessment modalities (e.g., tremor rating scales, Stewart–Holmes maneuver, visual tracking, digitized spirography and accelerometric techniques, accelerometry–electromyography coupling), and therapeutic options (i.e., including pharmacological agents, botulinum toxin A injections; deep brain stimulation or thalamotomy reserved for severe, disabling, or pharmaco-resistant tremors). Some suggestions are provided to help overcome the unmet needs and guide future therapeutic and diagnostic studies in this complex disorder.
Palliative Care in High-Grade Glioma: A Review
Authors: Crooms Rita C. , Goldstein Nathan E. , Diamond Eli L. , Vickrey Barbara G.
Published: October 2020

High-grade glioma (HGG) is characterized by debilitating neurologic symptoms and poor prognosis. Some of the suffering this disease engenders may be ameliorated through palliative care, which improves quality of life for seriously ill patients by optimizing symptom management and psychosocial support, which can be delivered concurrently with cancer-directed treatments. In this article, we review palliative care needs associated with HGG and identify opportunities for primary and specialty palliative care interventions. Patients with HGG and their caregivers experience high levels of distress due to physical, emotional, and cognitive symptoms that negatively impact quality of life and functional independence, all in the context of limited life expectancy. However, patients typically have limited contact with specialty palliative care until the end of life, and there is no established model for ensuring their palliative care needs are met throughout the disease course. We identify low rates of advance care planning, misconceptions about palliative care being synonymous with end-of-life care, and the unique neurologic needs of this patient population as some of the potential barriers to increased palliative interventions. Further research is needed to define the optimal roles of neuro-oncologists and palliative care specialists in the management of this illness and to establish appropriate timing and models for palliative care delivery.
A Re-Appraisal of the Effect of Amplitude on the Stability of Interlimb Coordination Based on Tightened Normalization Procedures
Authors: de Poel Harjo J. , Roerdink Melvyn , Peper C. (Lieke) E. , Beek Peter J.
Published: October 2020

The stability of rhythmic interlimb coordination is governed by the coupling between limb movements. While it is amply documented how coordinative performance depends on movement frequency, theoretical considerations and recent empirical findings suggest that interlimb coupling (and hence coordinative stability) is actually mediated more by movement amplitude. Here, we present the results of a reanalysis of the data of Post, Peper, and Beek (2000), which were collected in an experiment aimed at teasing apart the effects of frequency and amplitude on coordinative stability of both steady-state and perturbed in-phase and antiphase interlimb coordination. The dataset in question was selected because we found indications that the according results were prone to artifacts, which may have obscured the potential effects of amplitude on the post-perturbation stability of interlimb coordination. We therefore redid the same analysis based on movement signals that were normalized each half-cycle for variations in oscillation center and movement frequency. With this refined analysis we found that (1) stability of both steady-state and perturbed coordination indeed seemed to depend more on amplitude than on movement frequency per se, and that (2) whereas steady-state antiphase coordination became less stable with increasing frequency for prescribed amplitudes, in-phase coordination became more stable at higher frequencies. Such effects may have been obscured in previous studies due to (1) unnoticed changes in performed amplitudes, and/or (2) artifacts related to inappropriate data normalization. The results of the present reanalysis therefore give cause for reconsidering the relation between the frequency, amplitude, and stability of interlimb coordination.

Long-term noise exposure often results in noise induced hearing loss (NIHL). Tinnitus, the generation of phantom sounds, can also result from noise exposure, although understanding of its underlying mechanisms are limited. Recent studies, however, are shedding light on the neural processes involved in NIHL and tinnitus, leading to potential new and innovative treatments. This review focuses on the assessment of NIHL, available treatments, and development of new pharmacologic and non-pharmacologic treatments based on recent studies of central auditory plasticity and adaptive changes in hearing. We discuss the mechanisms and maladaptive plasticity of NIHL, neuronal aspects of tinnitus triggers, and mechanisms such as tinnitus-associated neural changes at the cochlear nucleus underlying the generation of tinnitus after noise-induced deafferentation. We include observations from recent studies, including our own studies on associated risks and emerging treatments for tinnitus. Increasing knowledge of neural plasticity and adaptive changes in the central auditory system suggest that NIHL is preventable and transient abnormalities may be reversable, although ongoing research in assessment and early detection of hearing difficulties is still urgently needed. Since no treatment can yet reverse noise-related damage completely, preventative strategies and increased awareness of hearing health are essential.
Osteoconductive and Osteoinductive Surface Modifications of Biomaterials for Bone Regeneration: A Concise Review
Authors: Kazimierczak Paulina , Przekora Agata
Published: October 2020

The main aim of bone tissue engineering is to fabricate highly biocompatible, osteoconductive and/or osteoinductive biomaterials for tissue regeneration. Bone implants should support bone growth at the implantation site via promotion of osteoblast adhesion, proliferation, and formation of bone extracellular matrix. Moreover, a very desired feature of biomaterials for clinical applications is their osteoinductivity, which means the ability of the material to induce osteogenic differentiation of mesenchymal stem cells toward bone-building cells (osteoblasts). Nevertheless, the development of completely biocompatible biomaterials with appropriate physicochemical and mechanical properties poses a great challenge for the researchers. Thus, the current trend in the engineering of biomaterials focuses on the surface modifications to improve biological properties of bone implants. This review presents the most recent findings concerning surface modifications of biomaterials to improve their osteoconductivity and osteoinductivity. The article describes two types of surface modifications: (1) Additive and (2) subtractive, indicating biological effects of the resultant surfaces in vitro and/or in vivo. The review article summarizes known additive modifications, such as plasma treatment, magnetron sputtering, and preparation of inorganic, organic, and composite coatings on the implants. It also presents some common subtractive processes applied for surface modifications of the biomaterials (i.e., acid etching, sand blasting, grit blasting, sand-blasted large-grit acid etched (SLA), anodizing, and laser methods). In summary, the article is an excellent compendium on the surface modifications and development of advanced osteoconductive and/or osteoinductive coatings on biomaterials for bone regeneration.

Authors: Soliman Saied M. , Al-Rasheed Hessa H. , El-Faham Ayman
Published: October 2020

Herein, the synthesis and antimicrobial activities of [Mn(MorphBPT)(H2O)2NO3]NO3; (1) and [Mn(PipBPT)(H2O)2NO3]NO3; (2) complexes of the pincer-type tridentate ligands MorphBPT; 4-(4,6-di(1H-pyrazol-1-yl)-1,3,5-triazin-2-yl)morpholine and PipBPT; 2-(piperidin-1-yl)-4,6-di(1H-pyrazol-1-yl)-1,3,5-triazine are presented. Both complexes have slightly distorted octahedral coordination geometry. Their molecular packing depends on O–H···O, C–H···O hydrogen bonds and anion–π stacking contacts. Hirshfeld analysis was used to quantify the different contacts. Both complexes exhibited better anti-fungal activity than the standard Fluconazole and comparable antibacterial activity to Gentamycin against Staphylococcus aureus and Escherichia coli microbes. Moreover, complexes 1 and 2 are biologically more active than the free ligands against these microbes.
Diversity, Interaction, and Bioprospecting of Plant-Associated Microbiomes
Authors: Acuña Jacquelinne J. , Jorquera Milko A.
Published: October 2020

Plant-associated microbiomes have been suggested as pivotal for the growth and health of natural vegetation and agronomic plants. In this sense, plant-associated microbiomes harbor a huge diversity of microorganisms (such as bacteria and fungi) which can modulate the plant host response against pathogens and changing environmental conditions through a complex network of genetic, biochemical, physical, and metabolomics interactions. Advances on next-generation omic technologies have opened the possibility to unravel this complex microbial diversity and their interactive networks as never described before. In parallel, the develop of novel culture-dependent methods are also crucial to the study of the biology of members of plant-associated microbiomes and their bioprospecting as sources of bioactive compounds, or as tools to improve the productivity of agriculture. This Special Issue aims to motivate and collect recent studies which are focused on exploring the diversity and ecology of plant-associated microbiomes and their genetic and metabolic interactions with other microorganisms or their plant hosts, as well as their potential biotechnological applications in diverse fields, such as inoculants for agriculture.
Prioritizing Management of Non-Native Eurasian Watermilfoil Using Species Occurrence and Abundance Predictions

Published: October 2020

Prioritizing the prevention and control of non-native invasive species requires understanding where introductions are likely to occur and cause harm. We developed predictive models for Eurasian watermilfoil (EWM) (Myriophyllum spicatum L.) occurrence and abundance to produce a smart prioritization tool for EWM management. We used generalized linear models (GLMs) to predict species occurrence and extended beta regression models to predict abundance from data collected on 657 Wisconsin lakes. Species occurrence was positively related to the nearby density of vehicle roads, maximum air temperature, lake surface area, and maximum lake depth. Species occurrence was negatively related to near-surface lithological calcium oxide content, annual air temperature range, and average distance to all known source populations. EWM abundance was positively associated with conductivity, maximum air temperature, mean distance to source, and soil erodibility, and negatively related to % surface rock calcium oxide content and annual temperature range. We extended the models to generate occurrence and predictions for all lakes in Wisconsin greater than 1 ha (N = 9825), then prioritized prevention and management, placing highest priority on lakes likely to experience EWM introductions and support abundant populations. This modelling effort revealed that, although EWM has been present for several decades, many lakes are still vulnerable to introduction.
Filtering Statistics on Networks

Published: October 2020

Compression, filtering, and cryptography, as well as the sampling of complex systems, can be seen as processing information. A large initial configuration or input space is nontrivially mapped to a smaller set of output or final states. We explored the statistics of filtering of simple patterns on a number of deterministic and random graphs as a tractable example of such information processing in complex systems. In this problem, multiple inputs map to the same output, and the statistics of filtering is represented by the distribution of this degeneracy. For a few simple filter patterns on a ring, we obtained an exact solution of the problem and numerically described more difficult filter setups. For each of the filter patterns and networks, we found three key numbers that essentially describe the statistics of filtering and compared them for different networks. Our results for networks with diverse architectures are essentially determined by two factors: whether the graphs structure is deterministic or random and the vertex degree. We find that filtering in random graphs produces much richer statistics than in deterministic graphs, reflecting the greater complexity of such graphs. Increasing the graph’s degree reduces this statistical richness, while being at its maximum at the smallest degree not equal to two. A filter pattern with a strong dependence on the neighbourhood of a node is much more sensitive to these effects.
Four-Objective Optimization of Irreversible Atkinson Cycle Based on NSGA-II

Published: October 2020

Variation trends of dimensionless power density (PD) with a compression ratio and thermal efficiency (TE) are discussed according to the irreversible Atkinson cycle (AC) model established in previous literature. Then, for the fixed cycle temperature ratio, the maximum specific volume ratios, the maximum pressure ratios, and the TEs corresponding to the maximum power output (PO) and the maximum PD are compared. Finally, multi-objective optimization (MOO) of cycle performance with dimensionless PO, TE, dimensionless PD, and dimensionless ecological function (EF) as the optimization objectives and compression ratio as the optimization variable are performed by applying the non-dominated sorting genetic algorithm-II (NSGA-II). The results show that there is an optimal compression ratio which will maximize the dimensionless PD. The relation curve of the dimensionless PD and compression ratio is a parabolic-like one, and the dimensionless PD and TE is a loop-shaped one. The AC engine has smaller size and higher TE under the maximum PD condition than those of under the maximum PO condition. With the increase of TE, the dimensionless PO will decrease, the dimensionless PD will increase, and the dimensionless EF will first increase and then decrease. There is no positive ideal point in Pareto frontier. The optimal solutions by using three decision-making methods are compared. This paper analyzes the performance of the PD of the AC with three losses, and performs MOO of dimensionless PO, TE, dimensionless PD, and dimensionless EF. The new conclusions obtained have theoretical guideline value for the optimal design of actual Atkinson heat engine.
Research on Power Demand Side Information Quality Indicators and Evaluation Based on Grounded Theory Approach
Authors: Zhu Yiping , Zhou Zan
Published: October 2020

High-quality power demand side information is necessary for scientific decision-making of power grid construction projects. Literature research shows that the current demand side management (DSM) information quality theories and methods need to be improved, and the information quality indicators and evaluation work are essential. In this paper, based on the grounded theory, about 250 copies of relevant literatures and interview records are reviewed. Through open coding, spindle coding, and selective coding, 105 initial concepts are finally extracted to 35 categories and 10 main categories. On this basis, four information dimensions including load extraction, monitoring, management, and government planning are summarized. An index system containing 34 indicators for DSM information quality evaluation on the power demand side is constructed. Finally, using matter-element extension evaluation method, a case study in China is performed to verify the feasibility and scientificity of the indexes. The results show that DSM information quality evaluation indexes are effective, and the evaluation method is also applicable. The establishment of DSM information quality indicators and the evaluation methods in this paper can provide a reference for similar information quality evaluation work in power systems.

Published: October 2020

(1) Background: The preparation and characterization of novel fully injectable enzymatically hardened tetracalcium phosphate/monetite cements (CXI cements) using phytic acid/phytase (PHYT/F3P) hardening liquid with a small addition of polyacrylic acid/carboxymethyl cellulose anionic polyelectrolyte (PAA/CMC) and enhanced bioactivity. (2) Methods: Composite cements were prepared by mixing of calcium phosphate powder mixture with hardening liquid containing anionic polyelectrolyte. Phase and microstructural analysis, compressive strength, release of ions and in vitro testing were used for the evaluation of cement properties. (3) Results: The simple possibility to control the setting time of self-setting CXI cements was shown (7–28 min) by the change in P/L ratio or PHYT/F3P reaction time. The wet compressive strength of cements (up to 15 MPa) was close to cancellous bone. The increase in PAA content to 1 wt% caused refinement and change in the morphology of hydroxyapatite particles. Cement pastes had a high resistance to wash-out in a short time after cement mixing. The noncytotoxic character of CX cement extracts was verified. Moreover, PHYT supported the formation of Ca deposits, and the additional synergistic effect of PAA and CMC on enhanced ALP activity was found, along with the strong up-regulation of osteogenic gene expressions for osteopontin, osteocalcin and IGF1 growth factor evaluated by the RT-qPCR analysis in osteogenic αMEM 50% CXI extracts. (4) Conclusions: The fully injectable composite calcium phosphate bicements with anionic polyelectrolyte addition showed good mechanical and physico-chemical properties and enhanced osteogenic bioactivity which is a promising assumption for their application in bone defect regeneration.

Published: October 2020

Paracoccidioides is a genus of thermodimorphic fungi that causes paracoccidioidomycosis. When in the host, the fungus undergoes several challenges, including iron deprivation imposed by nutritional immunity. In response to the iron deprivation triggered by the host, the fungus responds in a ternary manner using mechanisms of high affinity and specificity for the uptake of Fe, namely non-classical reductive iron uptake pathway, uptake of host iron proteins, and biosynthesis and uptake of siderophores. This triple response resembles the rhythmic structure of a waltz, which features three beats per compass. Using this connotation, we have constructed this review summarizing relevant findings in this area of study and pointing out new discoveries and perspectives that may contribute to the expansion of this “little iron waltz”.
Violencia y género: cuerpos vulnerables, vidas precarias y resistencia en las cartas de Mari
Authors: Oliver María Rosa , Urbano Luciana
Published: October 2020

El objetivo de este trabajo es ahondar en las formas de violencia ejercidas sobre las mujeres desde las fuentes paleobabilónicas de Mari (1775-1762 a.n.e.). Este corpus documental posee una nutrida “correspondencia femenina”, allí las mujeres están presentes por doquier, las de la elite en especial, pero también otras de sectores subalternos, las servidoras de las reinas y princesas, las esclavas, las mujeres del común. Todas ellas están atravesadas, aunque de maneras diferentes, por los mecanismos masculinizantes del poder que las posicionan en lugares de acatamiento de la norma, extremando la vulnerabilidad de sus cuerpos, hacinándolas en una precariedad que en muchos casos pone sus vidas en peligro. Nuestro objetivo es abordar esos múltiples mecanismos de violencia sin desconocer las jerarquías de clase y las posibilidades de resistencias y solidaridades. Si bien es cierto que las concepciones sobre violencia de género son muy actuales, nos parece pertinente historizar la violencia y revisitar las fuentes antiguas desde esta perspectiva.

During the movement of the tractor in the unit with the lockless grabs on the roughness of the terrain on the cuttings there are fluctuations that cause jumps of the working fluid in the hydraulic system. This leads to loss of fluid through the gaps and seals of the moving elements of the pump and hydraulic cylinders. For laboratory studies of these phenomena, a laboratory installation was made with the introduction of a pneumatic-hydraulic accumulator of the A5579-0 series into the hydraulic circuit. Laboratory tests were carried out, which showed that the pneumohydraulic battery allows, due to the energy accumulated during operation, to reduce the pressure spikes of the working fluid in the hydraulic system. This reduces the dynamic load on the metal structure of the grip, the hydraulic pump drive and the tractor transmission, as well as increases the volumetric efficiency. After processing waveforms of operating modes to capture with energy saving hydraulic drive using the program STATISTICA was established replications of individual load magnitudes and histograms of pressure without the use of a hydropneumatic accumulator and to its use. It was found that the energy recovery system reduces the pressure spikes of the working fluid during transients by 1.4-1.7 times and allows you to store power within 1.7 ... 2.1 kW.

Published: October 2020

The article presents the results of a brief comparative analysis of specialized CAD systems used in the furniture industry. In particular, it is noted that the functioning of CAD for mechanical engineering is based on geometric models of design objects, which are a mathematical reflection of information about the properties of forms and structural features of the furniture products. Therefore, such CAD systems can be quickly and relatively easily adapted to solve the problems of the furniture industry. At the same time, specialized CAD furniture products were widely used. This is determined by the engineering and artistic nature of the furniture products. The functional capabilities of most modern furniture CAD systems provides a high level of design automation, including products modeling, the creation of drawings and cutting maps of structural and decorative-facing materials, and the preparation of control programs for automated technological equipment.
MODELING THE TRANSMISSION OF A MOBILE MEANS ON TIRES OF EXTRA LOW PRESSURE TAKING INTO ACCOUNT THE INFLUENCE OF ROAD UNEQUALITIES

Published: October 2020

The work is devoted to the problem of negative dynamic effects on the transmission and the engine of a mobile vehicle on ultra-low pressure tires. When using this propulsion device on technological means, the load on wheel reducers (final drives), half shafts, differential, final drive, on the shaft and cardan drive hinges, spline connection, transfer case, elastic transmission clutch, transmission drive and driven shafts sharply increases with gears, clutch driving and driven parts, engine crankshaft. When the load on these elements is excessive, their service life is reduced, and excessive loading can even lead to a sudden failure. Since each of these nodes is somehow fixed on the frame of the vehicle, to which vibrations from the unevenness of the rolling surfaces perceived by the propulsion are transmitted, they also have an additional effect. For a comprehensive assessment of the dynamic loading of the transmission and the engine of a mobile vehicle equipped with ultra-low pressure tires, taking into account the influence of road irregularities, a mobile vehicle model was compiled. The model will allow a more accurate calculation of the basic characteristics of technological equipment transmissions on ultra-low pressure tires.

The work proposes an improved combined power supply system for forest transport machines, consisting of a small-power electromagnetic generator and a thermoelectric generator, which will increase the efficiency and environmental friendliness of the machines used in the forest complex. The global and domestic modern scientific potential is tuned to solve an urgent problem, namely: the use of new technologies to obtain nanomaterials. The result of the use of new materials is the development and implementation of highly efficient energy-saving systems [1].

When designing modern forest transport machines, elements of modern electronics, energy, communication systems, heating and air conditioning are widely used, where polymer materials (PM) are widely used. Especially often they are used in the form of gaskets, films, coatings and adhesive layers. Harsh operating conditions for timber transport quite often require the use of PM products with special properties (increased thermal conductivity) while maintaining mechanical characteristics [2].

As you know, environmental requirements for vehicles of any kind are increasing every year. One of the ways to improve environmental friendliness is to increase profitability, and this is possible with the modernization of forest transport machines, in particular, through the use of energy-saving technologies, which undoubtedly include the use of a thermoelectric generator as a power source for the onboard network of a forest transport machine.

The article proposes an assessment of thе conditions for thе sustainablе devеlopmеnt of thе timber industry complex, taking into account the correlation analysis of indicators. The calculation of the correlation coefficients made it possible to identify the crampedness and direction of the relationship of the studied conditions. The process of development of innovations in production, in the creation of new materials and other areas, like any technogenic impact, can cause a negative, adverse effect on the environment, the protection of which becomes one of the priority tasks of modern ecologically oriented economic development. This characteristic of the conditions can be further used in the regional administration for an adequate diagnosis of the current situation, to identify causal relationships between indicators and forecasting the parameters of the balanced development of the timber industry complex. To achieve sustainable development of the forestry complex, it is extremely important to coordinate the three main elements - еconomic growth, social intеgration and еnvironmental protеction. The concept of sustainable development of the forestry complex should provide for continuous improvement based on the use of fewer forest resources for production and minimization of harmful effects on the environment. The duration of forest cultivation necessitates early adoption of strategic management decisions in the fiеld of forest managеment and rеproduction of forest resources. A necessary condition for the successful solution of such a problem is the formation of conditions for the sustainable development of the timber industry complex. The proposed conditions do not contradict the foreign requirements for the financial analysis of the complex, since it has all the necessary sections, supplemented and adapted to the domestic conditions for carrying out economic activities and taking into account the specifics of financial monitoring.

Published: October 2020

In e-commerce, profit depends on both quantitative and qualitative indicators - Internet services and their quality, trends in market size, fluctuations in business activity depending on the season, customer inflows and their outflows, product costs. All of these indicators have fuzzy descriptions. E-commerce is a dynamic segment of economic activity. Despite the general principles of marketing, this direction has a number of unique opportunities. The main focus of e-commerce is the sale of services and goods using the Internet. At the same time, the possibilities of e-commerce are very diverse. In this article, we will consider one of the possibilities - an online store. This is a software product that is designed as a Web site, which is further used as a platform for shopping and selling goods. This article discusses using the fuzzy logic apparatus to build an e-commerce model and evaluate alternatives. The statement of the problem is as follows: with many alternatives, we have outcomes: in the case of certainty, one, and with uncertainty, perhaps a certain number of options. Each specific outcome is characterized by a certain state that the object will have after implementing the alternative described by the efficiency criterion that determines the value of the outcome preference indicator. It is necessary to determine the strategy for choosing the most preferable alternative, corresponding to the performance indicator.

The results of a study of red oak crops located on the territory of the Kurdzhip precinct forestry of the Republic of Adygea (western part of the North Caucasus) are presented. The characteristic of red oak, as a tree species, is less demanding on soil conditions compared to other forest-forming species and has high decorative properties, due to which it is used alone for planting in open areas, as a hedge along roads, individual tracts in parks, squares in the form of oak groves. It goes well both in pure stands and in combination with pine, beech, hornbeam, elm, ash, linden, mountain ash, maple. It is able to grow on sandy loam and loamy podzolic soils without stagnant moisture, mainly along river banks. It grows poorly on calcareous and moist soils. Due to its well-developed root system, wood is resistant to wind. Red oak is characterized by good resistance to damage by entomo - and phyto pests [1, 5]. The paper analyzes the taxation indicators of red oak and related species crops, and plots of growth progress along the height and diameter of the crops are constructed. The growth and productivity advantage of the oak over red oak has been established.
