Authors: Ciężkowski Paweł , Maciejewski Jan , Bąk Sebastian , Kwaśniewski Arkadiusz
Published: October 2019

The results of studies of the crushing process in a double toggle jaw crusher are presented. This process was carried out on six sets of crushing plates. The first three of them are used in industrial crushers – plates with a flat working surface and a triangular profile (in this work, under consideration were profiles with teeth angle γ = 90°). The fourth and fifth type refer to plates with a variable pitch t and teeth height with a triangular shape of the teeth. In the sixth solution, plates with variable pitch and width of the wedged teeth are proposed.

The results of the basic process parameters are shown, that is, average degree of fineness n, technical performance Wt
, crushing energy L and crushing force F, sieve analysis of crushing product. The obtained results are the basis for the assessment of the suitability of various types of plates, especially plates with a new profile, which have an altered shape in comparison with the plates used in crushers so far.

The crushing tests were carried out with the same dimension of outlet slot er
= 24 mm, close to the pitch size for plates with triangular profile. Tests were performed on the “Mucharz” sandstone. Samples from a series of blocks of different size and geometric shape were prepared. This work also presents feed mass influence on crushing process efficiency.

The plates with variable pitch and width of teeth are beneficial because of lower crushing force and energy.

The Cancer Observatory of Cali, a priority
Authors: Abreu Claudia Patricia , Tobar Blandon María Fernanda , Holguín Jorge Alirio
Published: October 2019

In the last issue of Colombia Médica, the Cali Population Registry of Cancer (RPCC, for its initials in Spanish) documented that important advances in cancer control have been achieved (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6018818/). Mortality due to this group of diseases has decreased significantly during the last 25 years, thanks to the partial control of cancers related to infectious agents (stomach and cervix) and cancers associated with tobacco consumption (lung, bladder, oral cavity). However, there is less control of cancers related to screening activities (breast, prostate and colorectal), and hematolymphoid tumors that have successful treatment options with chemotherapy. As a result, cancer survival in children and adults is 20 percentage points below that observed in Europe and the United States 1.
One strategy to improve the indicators is the creation of a cancer observatory in the city. Health observatories are conceived as smart, proactive, dynamic, synchronic and participatory systems that generate knowledge for the formulation of policies and strategies that allow to impact, in a positive way, the social determinants of health (2). With this perspective and in congruence with the technical line of health observatories given by the Ministry of Health and Social Protection, it is necessary to generate strategies; to have articulation spaces; and to integrate sources of information, which in addition to being standardized and synchronized, facilitate the monitoring and identification of trends in the behavior of events, and the understanding and explanation of the health situation of the population based on complex analyses of inequalities and health vulnerabilities 2.
Granica państwa jako kategoria wielowymiarowa
Authors: Balawajder Grzegorz
Published: October 2019

Istnienie granic państwowych wynika przede wszystkim z przypisania państwom terytorium a także z właściwego wspólnotom ludzkim instynktu terytorialności. Granica państwa, wyznaczając położenie geograficzne terytorium, określa nie tylko obszar państwa, ale spełnia również określone funkcje, które w podstawowym wymiarze mają charakter wewnętrzny i zewnętrzny. Mimo że na wielu obszarach granice zachowały tradycyjną funkcję bariery, współczesne granice nie funkcjonują już w ten sam sposób, jak jeszcze w niedalekiej przeszłości. W warunkach globalizacji kultury oraz internacjonalizacji polityki i gospodarki nastąpiło otwarcie granic i związane z tym osłabienie kontroli granicznej, stanowiącej dotychczas barierę dla przepływu ludzi, dóbr, kapitału i idei. Oznacza to, że współczesna percepcja granic państwowych dotyczy nie tylko zmian zachodzących w obrębie instytucji państwa i jego polityk, ale również wiąże się ze zmianami w kontekście redefinicji obywatelstwa, suwerenności i tożsamości narodowej.

Task-Specific Sensitivity in Physical Function Testing Predicts Outcome in Patients With Low Back Pain
Authors: Trolle Nûno , Maribo Thomas , Jensen Lone Donbæk , Christiansen David Høyrup
Published: October 2019

Objective

To investigate the prognostic value of task-specific sensitivity in patients with low back pain by exploring whether task-specific sensitivity during physical function testing was associated with self-reported change in pain and disability.

Design

Prospective cohort study nested in a randomized controlled trial.

Methods

The study included 260 patients with low back pain, referred for evaluation in a secondary care setting. All patients completed questionnaires and underwent clinical examination by a physical therapist. Patients rated their pain intensity before and after completing a test battery measuring physical function and were classified into 4 categories—worse, unchanged, better, or no pain—depending on their pain response. At 3-month follow-up, outcomes were obtained by a postal questionnaire.

Results

Task-specific sensitivity significantly predicted pain, after adjusting for known prognostic factors. Patients in the no pain, better, and unchanged groups improved their pain score significantly more than patients in the worse pain group. Patients in the no pain group also improved their disability score significantly more compared to patients in the worse pain group, after adjusting for known prognostic factors.

Conclusion

Task-specific sensitivity predicted pain intensity after 3 months in patients with low back pain. The prognostic value appears limited with respect to disability. J Orthop Sports Phys Ther 2020;50(4):206–213. Epub 30 Oct 2019. doi:10.2519/jospt.2020.8953

The article has been devoted to theoretical issues of the digital advertising sphere, its tasks and features. The online advertising market development level has been estimated, based on analytical data. Digital advertising is a complex of analytical, technological and supporting tools, which are interconnected directly. It includes a system of methods and tools, which use digital channels to promote a product or brand, attract and retain customers. The main areas of digital advertising are display advertising, banner advertising, video advertising and contextual advertising. Digital advertising is not limited by the Internet, but it uses other communication resources such as television, radio, telephone, direct sales and direct contact. A key feature of digital advertising is its interactivity and formed on its basis analytical resources (consumers, their preferences, products, channels, etc.), that provide personalization. At its core, personalization is the process of understanding the true intentions, desires and needs of a person, as well as the transfer of relevant, targeted and significant experience for that person. In practical terms, this means building and using a customer model and managing customer experience. The article examines the properties of digital advertising and its implementation as a project. The interdisciplinary properties of digital advertising predetermine the cross-subject nature of the training of specialists in digital advertising: marketing and information technology specialists. To illustrate the given theoretical material a real project of digital advertising company for popular among young people food product has been presented. The project goals and concept, its plan and organization of execution, the tools of digital advertising used have been considered: chat bots, mobile version of the site, landing page, gamification, promo codes, CRM system, bloggers, SMM. It has been shown, how the assessment of digital advertising impact activities of the company and the costs of the project were carried out.
Digital strategies of companies: growth potential and reasons for failure
Authors: Butkovskaya G. , Sumarokova E.
Published: October 2019

Countries, industries and business leaders face an increasingly complex world characterized by the proliferation of new digital technologies, affecting productivity and causing organizational disruptions.Today the reward for success and the penalty for failure have become even greater than some time ago. Most digital strategies do not reflect how the digital environment is changing the fundamentals of the economy, the dynamics of industries, and the meaning of competition. Digital strategy must be seriously different from what we usually see now – otherwise failure is inevitable. Why is this possible at a time when almost every company in the world is thinking about its digital future? Why are so many digital strategies unsuccessful? The answer should be related to how much large and influential economic force the digital environment has become, and how it is becoming incompatible with traditional economic, strategic and operational models. The problems, especially standing out from their General number have been revealed in the article, recommendations to the heads of large organizations on the implementation of corporate digital strategies have been given. The ideas in this work are based on research, that has considered the importance of a more inclusive infrastructure to expand access to digital technologies and the emergence of new families of technologies in this scientific field. These ideas have been illustrated with evidence from the recent annual series of global market studies, which examine corporate practices in the light of digitalization.

Optimizing Electrostatic Similarity for Virtual Screening: A New Methodology
Authors: Puertas Martín Savíns , Lopez Redondo Juana , Pérez-Sánchez Horacio , Martínez Ortigosa Pilar
Published: October 2019

Ligand Based Virtual Screening (LBVS) methods are widely used in drug discovery as filters for subsequent in-vitro and in-vivo characterization. This means, increasing accuracy of LBVS approaches may have a huge impact on increasing chances of success. Since the databases processed in drug discovery campaigns are enormously large, this pre-selection process requires the use of fast and precise methodologies. The similarity between compounds can be measured using different descriptors such as shape, pharmacophore or electrostatic similarity. The latter is the goal of this work, i.e., we want to improve the process of obtaining the compounds most similar to a query in terms of electrostatic similarity. To do so, the current and widely proposed methodology in the literature is based on the use of ROCS to assess the similarity of compounds in terms of shape and then evaluate a small subset of them with ZAP for prioritization regarding electrostatic similarity. This paper proposes an alternative methodology that consists of directly optimizing electrostatic similarity and works with the entire database of compounds without using shape cut-offs. For this purpose, a new and improved version of the OptiPharm software has been developed. OptiPharm implements a parameterizable metaheuristic algorithm able to solve any optimization problems directly related to the involved molecular conformations. We show that our new method completely outperforms the classical proposal widely used in the literature. Accordingly, we are able to conclude that many of the compounds proposed with our novel approach could not be discovered with the classical one. As a result, this methodology opens up new horizons in Drug Discovery.
Dynamic Effects May Affect Hammett Linear Free Energy Relationship
Authors: Xu Xinyu , Han Zongchang
Published: October 2019

The aromatic nucleophilic substitution reaction in the Clayden rearrangement reaction has an abnormal Hammett linear free energy relationship1. Inspired by the concertedstepwise variation of the aromatic nucleophilic substitution reaction in 20182, we determined the mechanism of Clayden rearrangement reaction under several conditions by DFT calculation then explained the mechanism diversity. We also found that there is a significant dynamic effect in the system due to the emergence of dynamic intermediates, which may be one of the reasons for the Hammett linear free energy relationship.
Simulation of Light Propagation in Photochemical Fixed-Bed Reactors Using a BRDF-Based Model
Authors: Ramos Bruno , Grisafi Franco , Brucato Alberto , Teixeira Antonio Carlos Silva Costa
Published: October 2019

Modelling light transport in fixed-bed photochemical reactors can be challenging if the geometry of the packing is the object of investigation. In this manuscript, we present a physically-based model of light transport for the simulation of fixed-bed photochemical reactors to be coupled with explicit consideration of reactor geometry: spatial properties of the fixed bed, such as size, shape, distribution and quality of the surface of packing particles are used as input variables. The existence of a catalytic coating on the packing surface, and its major properties such as spectral coefficient of absorption and surface rugosity can also be easily coupled with the light propagation algorithm. The model was built upon the framework of the bidirectional reflectance distribution function (BRDF), using the microfacets theory (MFT) to evaluate an approximate solution. As an example of application, easily measurable experimental data, such as UV absorption/extinction spectra and surface roughness, and readily available literature data on spectral refractive indices are used as inputs to calculate (i) the fate of the irradiated energy (percentage absorbed, transmitted and scattered-out) and (ii) the spatial distribution of the scattered rays. Taken together, these output data should offer the engineer guidelines for the design of fixed-bed photochemical reactors with optimised light collection and distribution.
Ligand Redox Non-Innocence in [Coᴵᴵᴵ(TAML)]0/‒ Complexes Affects Nitrene Formation

Published: October 2019

The redox non-innocence of the TAML scaffold in cobalt-TAML (Tetra-Amido Macrocyclic Ligand) complexes has been under debate since 2006. In this work we demonstrate with a variety of spectroscopic measurements that the TAML backbone in the anionic complex [CoIII(TAMLred)]- is truly redox non-innocent, and that one-electron oxidation affords [CoIII(TAMLsq)]. Multi-reference (CASSCF) calculations show that the electronic structure of [CoIII(TAMLsq)] is best described as an intermediate spin (S = 1) cobalt(III) center that is antiferromagnetically coupled to a ligand-centered radical, affording an overall doublet (S = ½) ground-state. Reaction of the cobalt(III)-TAML complexes with PhINNs as a nitrene precursor leads to TAML-centered oxidation, and produces nitrene radical complexes without oxidation of the metal ion. The ligand redox state (TAMLred or TAMLsq) determines whether mono- or bis-nitrene radical complexes are formed. Reaction of [CoIII(TAMLsq)] or [CoIII(TAMLred)]- with PhINNs results in formation of [CoIII(TAMLq)(N•Ns)] and [CoIII(TAMLq)(N•Ns)2]-, respectively. Herein, ligand-to-substrate single-electron transfer results in one-electron reduced Fischer-type nitrene radicals (N•Ns-) that are intermediates in catalytic nitrene transfer to styrene. These nitrene radical species were characterized by EPR, XANES, and UV-Vis spectroscopy, high resolution mass spectrometry, magnetic moment measurements and supporting CASSCF calculations.

Determinants of Small Business Owner Loan
Authors: Ma Jiameng
Published: October 2019

Shareholders and debtholders have diverging objectives. Shareholders are residual claimants whereas debtholders are fxed claimants to frm’s assets. In leveraged frms, shareholders may increase the value of their claims at the expense of debtholders. The presence of shareholders being debtholders is a smart interest alignment, providing a solution to shareholder-debtholder conﬂicts. This paper focuses on small businesses, which play an important role in the United States economy but are generally neglected by academia. Utilizing National Survey of Small Business Finance (NSSBF) data, this paper shows that frms with higher agency cost of debt are more likely to issue owner loan. The incidence of small business owner loan is positively associated with external lending diffculty, low shareholder agency cost and frm valuation diffculty.

Lumefantrine comparative study: single crystal, powder X-ray diffraction, Hirshfeld surface, and thermal analysis
Authors: De Freitas-Marques M.B. , Yoshida M.I. , Fernandes C. , Rodrigues B.L. , Mussel W.N.
Published: October 2019

Lumefantrine is an antimalarial drug and its crystal structure is still absent in the CCDC database. The authors propose a method to obtain the single crystal of this compound and characterize it by single crystal X-ray diffraction (XRD), FTIR, and thermal analysis. Intermolecular interactions are rationalized using the Hirshfeld surface analysis. Ethanol and dichloromethane (1:1 v/v) are used to crystallize the single crystals. The compound crystallizes in the space group P21 with a = 8.7830(11) Å, b = 9.4326(7) Å, c = 15.8299(16) Å, and β = 95.560(9)°, with two molecules in each unit cell. CIF fully simulates the PXRD results. The measured characteristic IR absorption bands belong to the pure material. The single crystal melting point is 128.6 °C (Tonset); the heat of fusion (ΔHfus) is 73.2 J/g, and the thermal degradation process starts at 219 °C, which is confirmed by two steps of the mass loss in the thermogravimetry curve. The CCDC deposit number is 1877120.

telecommunication channels, which allows using already known hashing methods to compare
generated codegrams and transmitted messages for their correspondence, which increases the
level of cryptographic stability of the transmitted data and the reliability of the received data. The
developed schemes of algorithms for generating codеgrams and their decryption using the
proposed approach make it possible to gradually demonstrate the implementation of procedures
for generating codegrams and their hash codes using both shortening and lengthening the code.
Further research should prove from a practical point of view the effectiveness of using this
approach when transmitting a message regarding the preservation of its integrity and
authenticity. Therefore, it is necessary to develop a test system that should implement the
proposed approach, as well as evaluate the results obtained.unication channels, which would ensure the proper level of

This article is about criteria of reliability of information. The validity period of the information
has been determined. It is established that an important stage of selection, development of
methods and mechanisms for ensuring the reliability of information is the analysis of the
processes of its processing. The definition of the information reliability assessment is given, and it
is also established that the complexity of the information reliability assessment is information
evaluation. To assess the accuracy of information, such features as the doubtfulness of the facts
presented, the emotional coloring of the content, the tone of the content in relation to an object or event, the sensational content, the hidden content. These features will be based on monitoring the
reliability of information in the information space, which aims to minimize the subjectivity of
peer review of the content of authors from the point of view of their influential orientation
towards individuals of the information space. In order to minimize this subjectivism, the basis of
evaluations is the key criteria for the reliability of information, which, unlike estimates, are
largely fully measured: the criterion of balance of information, the criterion for separating facts
from opinions, the criterion for the accuracy and reliability of information, the criterion for
completeness of information. Thus, there is a need to create an algorithm for assessing the
reliability of information in the information space, which makes it possible to investigate
information resources for the impact on them, identify problems of information security in a
timely manner, recommend proven solutions for use at critical sites, organize and to carry out
special trainings at the state level, etc.

Published: October 2019

In this article research to the robustness of recommendation systems with collaborative filtering
to information attacks, which are aimed at raising or lowering the ratings of target objects in a
system. The vulnerabilities of collaborative filtering methods to information attacks, as well as the
main types of attacks on recommendation systems - profile-injection attacks are explored. Ways to
evaluate the robustness of recommendation systems to profile-injection attacks using metrics such
as rating deviation from mean agreement and hit ratio are researched. The general method of
testing the robustness of recommendation systems is described. The classification of collaborative
filtration methods and comparisons of their robustness to information attacks are presented.
Collaborative filtering model-based methods have been found to be more robust than memorybased
methods, and item-based methods more resistant to attack than user-based methods.
Methods of identifying information attacks on recommendation systems based on the
classification of user-profiles are explored. Metrics for identify both individual bot profiles in a
system and a group of bots are researched. Ways to evaluate the quality of user profile classifiers,
including calculating metrics such as precision, recall, negative predictive value, and specificity
are described. The method of increasing the robustness of recommendation systems by entering
the user reputation parameter as well as methods for obtaining the numerical value of the user
reputation parameter is considered. The results of these researches will in the future be directed
to the development of a program model of a recommendation system for testing the robustness of
various algorithms for collaborative filtering to known information attacks.
Características de la actividad enzimática y el humus en suelos de chinampa.
Authors: Reyes-Ortigoza Amada Laura
Published: October 2019

The chinampas are protected natural areas that have suffered degradation due to saline contamination and type of management. The objective was to study enzymatic activity and type of humus in chinampas with different salinity, land use and geographical location. Forty-five soil samples were studied, 15 at each site (Xochimilco, San Gregorio Atlapulco (SGA) and Tláhuac). Each site had a different use: five had pastures, five had agricultural crops and five were abandoned. pH, EC, saline ions, enzymatic activity (glucosidase, phosphatase, urease, sulfatase, catalase and dehydrogenase) and carbon in humic substances were evaluated. EC, PSI and pH classified the cultivated soils of SGA and Xochimilco as saline, but in Tláhuac the soils of abandoned and pasture chinampas were sodic saline. Geographic location and land use changed enzyme activity (except for urease and glucosidase) and characteristics of the humus [percentages of carbon of humic acids (HA) (humic acids), fulvic acids (FA), and humins]. There were statistical differences (Tukey P < 0.05). The cultivated soils had more urease, phosphatase and sulfatase activity, while in the pasturelands dehydrogenase and catalase were more active. Higher carbon content in AH was found in pastureland and chinampas of Tlahuac, while in SGA and abandoned chinampas carbon content was higher in FA.

This work was conducted with the objective to evaluate the effect of vermicompost application on chemical characteristics, energetic parameters and amino acids prof ile of hybrid race corn grain cultivated under open-f ield and rained conditions. The experiment was accomplished under a randomized complete design with three repetitions. Three treatments were evaluated: 1) Maize after inoculation with a commercial mycorrhizal arbuscular fungi mixture (Tec Myc 60®) plus vermicompost (V+M); vermicompost (V) and chemical fertilization (CF). Starch content in grain was 1.9% higher in V+M treatment in comparison with chemical, whereas crude protein, ether extract, crude f iber, acid detergent f iber, neutral detergent f iber, total phosphorous and phytic phosphorous were not different between treatments. Energetic parameters were not different between three treatments. 17 amino acids were evaluated of wich only tryptophan, leucine, valine, histidine and aspartic acid were higher in CF and V treatments in comparison with V+M treatment. In conclusion, it is possible to cultivate maize using vermicompost as fertilizer because chemical characteristics, energetic parameters and amino acids prof ile in maize grain were not affected compared with the maize cultivated with vermicompost added with biofertilizers (V+M) or with corn cultivated with chemical fertilizers (CF).

Balanced and timely nutrition is important to ensure the yield and quality of avocado (Persea americana Mill.) fruit. This research was carried out in the cv. Méndez with the objectives of a) to describe the dynamics of fruit growth and the process of dry matter accumulation in mesocarp, b) to quantify the concentration and accumulation of nutrients in the mesocarp (pulp) during fruit development. In a commercial orchard with site-specif ic fertilization, 20 trees were selected and 30 summer flowering inflorescences per production cycle (2014-15, 2015-16 and 2016-17) were marked in each one. Five fruits per tree were randomly collected in f ive stages of development, from olive size to harvest, and the dry matter of the mesocarp and the concentrations of N, P, K, Ca, Mg, S, Fe, Cu, Mn, Zn and B in this tissue were quantif ied. The fruit required 300 days from anthesis to harvest. It showed accelerated growth in the f irst three stages of development (S-Olive, S-I and S-II) and lower growth in the last stage (S-III). Dry matter accumulation was constant during fruit development, although the largest accumulation occurred in S-III. In general, the concentration of nutrients in the mesocarp decreased with fruit development and its accumulation increased. The greatest fruit growth occurred in the f irst 185 post-anthesis days, when the mesocarp accumulated less than one-third of the total nutrients required until harvest. The results indicate the need to review how nutrients are supplied to the tree, to make sure they are adequately provided during fruit development.

The object of study – Vaccinium vitis-idaea L. were planted on the parterre of the Summer garden of St. Petersburg in 2011 in the number of copies 7545 Shrubs were planted in the 3-line with a length of 401 m and a total area 201 m2. The aim of the study is to identify the causes of intensive drying of cowberry shrubs in the Summer garden of St. Petersburg. Six years of experience in the use of cowberries showed that there is a constant decline of these plants. Each year, about 14% of plants dry up, but in some years, the proportion of falloff can be up to 20% of their total number. Planting material comes to the Summer garden from Europe, due to the lack of nurseries in Russia cowberries grown for decorative purposes. The safety of cowberries at the moment is about 62.5%. The obvious cause of drying could not be identified. No significant fungal pathogens were found on leaves and shoots. The dependence of the drop from the ongoing agricultural activities, recreational load, natural light planting, humidity, temperature and chemical composition of the soil is not currently established.
