The Pure Intergenerational Problem and the UNESCO Decade of Education for Sustainable Development
Authors: Vladimirova Katia
Published: November 2019

This article aims to bring together some theory – research on climate  ethics, particularly the Pure Intergenerational Problem (PIP) introduced by Stephen Gardiner – and some practice – the new educational agenda proposed by the United Nations in 2002 and framed as the Decade of Education for Sustainable Development (DESD). PIP can be resolved (or rather, avoided) if a shift in values happens that would change the very context of the problem. On the other hand, DESD is aimed at promoting the values “inherent in sustainable development” and at enabling societal transformation and behavioral change. The main focus within the value shift in this article is on a particular set of values (principles, concerns) that relate present people to future generations in terms of moral responsibility. It is argued that the promotion of ethical considerations that are concerned with the distant future, and the future of humankind in general, can be a solution to the Pure Intergenerational Problem. The article also explores whether parts of this solution can already be found within the educational agenda of DESD.
Value of an Encounter from an Ethical Perspective
Authors: Najder-Stefaniak Krystyna
Published: November 2019

This article investigates the relationship between the possibilities of actualizing our encounters and the openness of human space. It describes various types of encounters and shows the correlations between the perception of difference and the inclination to contravene certain encounters. The effects of encounters based on antagonistic, complementary, dialectic, and synergistic thinking are explored in a way that helps to better understand the aims and consequences of encounters actualized in diverse frameworks of dialogue. Further, the impact of paradigms of reasoning on how the value of meetings is understood is described. The results of the modern perception of relationships in the subject-object scheme and in the ecosystem paradigm are presented. The latter allows for recognition that encounters can facilitate creative activity by expanding human space.

Między (re)konstrukcją a nostalgią. Współczesny polski i rosyjski neopoganizm w kontekście „postcolonial studies”
Authors: Nakoneczny Tomasz
Published: November 2019

The article proposes a look at contemporary neopoganism as a phenomenon that can be described in the context of postcolonial studies. However, analyzing neopaganism through the prism of the classic postcolonial terms seems to be insufficient to the author. Therefore, he proposes to supplement it with the concept of nostalgia. He also disagrees with the view that neopaganism is the part of the postmodern trend of contemporary culture.

Mieszkańcy rosyjskiej wsi wobec wyzwań postsowieckiej rzeczywistości w twórczości Iriny Mamajewej
Authors: Kalita Liliana
Published: November 2019

The paper analyses Irina Mamayeva’s short stories and tales that show the life in Russian rural areas during a dozen or so years following perestroika, and point out its influence on both individual life and that of a village community as a group. The picture of the rural areas in the 1990s and at the beginning of the 21st century is pessimistic, filled with images of dilapidating houses, companies being shut down, lack of transport connections. This material destruction is accompanied by the spiritual degradation of the inhabitants: poverty, unemployment, mutual aggression and the feeling of being abandoned by the previous system.

Futurystyczna uczta literacka (Władimir Sorokin, „Манарага”)
Authors: Zywert Aleksandra
Published: November 2019

In his latest novel Manaraga (2017) Sorokin comments on one of the most significant problems of modern times – the results of the anticipated death of the printed book as well as the related opposition between the original and the copy. The biggest problem, as the author suggests, is not the form of the already published literary classics but the absence of new classics, which can embrace ideas capable of awaking the humankind from its zest for comfort and motivating people for constructive progress.

Serum sickness-like reaction to a second generation antipsychotic drug
Authors: Kashani Paria , Afraz Saba , Lavi Sasson
Published: November 2019

Introduction: Serum sickness is a type III hypersensitivity reaction. Immune complex deposition activates complement pathways resulting in fever, vasculitic rash, arthritis and lymphadenopathy. Medications are known to trigger serum sickness-like reactions which clinically resemble serum sickness, however, are not thought to involve circulating immune complexes. The full pathophysiology is not clear. Risperidone is an atypical antipsychotic drug commonly used in the paediatric population.

Aim: To describe the diagnosis, disease course and outcome of a patient who developed serum sickness-like reaction secondary to risperidone.

Methods: Review of patient chart and medical interview in accordance with institutional research ethics board approval.

Results: The patient, a 7 year old male with Attention Deficit Hyperactivity Disorder, was started on risperidone 0.25 mg once daily. Within a week the dose was increased to 0.5 mg once daily. During the third week after initiation of medication, the patient developed generalized purpuric, confluent, maculopapular rash. Although the patient did not have any signs and symptoms of a viral illness, he was diagnosed with viral-induced exanthema and continued on risperidone. On day 28, he developed significant, bilateral swelling of upper and lower extremities, facial angioedema, lymphadenopathy, arthralgia and arthritis in ankles, knees, hands and elbows without fever. Investigations showed normal complement C3 and C4 levels. C1 esterase inhibitor, anti-nuclear antibody and urinalysis were normal. Erythrocyte sedimentation rate, C-reactive protein and leukocyte levels were elevated. The diagnosis of serum sickness-like reaction to risperidone was made and the patient subsequently treated with cetirizine, hydrocortisone, and prednisone for 1 week with significant improvement. Skin biopsy was declined by the patients’ parents and therefore was not performed. Provocative oral challenge to risperidone was not considered because of clear suggestive history and ethical consideration.

Conclusion: Psychotropic medications are known to cause cutaneous eruptions. Serum sickness-like reactions can happen upon exposure to risperidone. Clinicians should be aware of this potential adverse reaction that can develop weeks after therapy initiation, and be encouraged to discontinue risperidone when the suggestive symptoms emerges.

Statement of novelty: We describe a case of serum sickness-like reaction to risperidone in a paediatric patient. To our knowledge, this is the first case of serum sickness-like reaction to risperidone.

As sementes foram inoculadas antes de serem submetidas à teste de germinação. O tratamento químico mostrou-se ineficiente na proteção da semente de todas as culturas e estimulo de germinação. A T. harzianum aumentou o índice germinativo de sementes de alface, teve melhores valores em tamanho de sistema radicular na cultura do tomate e estimulou a emissão de radícula na cenoura. O B. subtilis destacou-se no acúmulo de matéria seca na cultura do tomate. Os microrganismos B. subtilis e T. harzianum apresentam potencial para tratamento de sementes de hortaliças.
Forms of expression and recovery of vigor in mature trees of Lagerstroemia indica L
Authors: Ivasko Júnior Severo , Lombardi Kátia Cylene , Bobrowski Rogério
Published: November 2019

The present study aimed to characterize different forms of vigor expression and its recovery in mature trees of Lagerstroemia indica L. planted in public spaces of Irati, Brazil. After measuring the vegetative vigor (shoot growth, internode length, leaf area and leaf color), physiological vigor (chlorophyll a and b content) and flowering vigor (inflorescence width and length) in the growing season of 2016, we applied lime and fertilizers in different treatments in the portion of soil under the dripline of each tree. These treatments consisted of an increase of 100% nitrogen, phosphorus and potassium contents measured in the soil, based on previous soil analysis. In order to evaluate the effect of fertilization, in the growing season of 2017 we remeasured the vigor of trees. We observed that treatments with potassium and phosphate fertilization provided the highest mean values for shoot growth, the mean distance of internodes, leaf area, inflorescence width and length. The variables dark green color index and content of chlorophyll a and b were not influenced by fertilizer treatments. Our findings show that fertilizers increased the expression of all variables related to vegetative vigor of L. indica in the urban environment, except for the dark green color index. This suggests .that nutrient availability is generally a limiting factor for the urban tree’s growth. The shoot length can be used to characterize the vegetative vigor, and the inflorescence length in the evaluation of the flowering vigor.

Study of LBHD1 Expression with Invasion and Migration of Bladder Cancer
Authors: Dong Chunhui , Liu Yihui , Yu Guiping , Li Xu , Chen Ling
Published: November 2019

LBHD1 (C11ORF48) is one of the ten potential tumor antigens identified by immunoscreening the urinary bladder cancer cDNA library in our previous study. We suspect that its expression is associated with human bladder cancer. However, the exact correlation remains unclear. To address the potential functional relationship between LBHD1 and bladder cancer, we examined the LBHD1 expression at the mRNA and protein level in 5 different bladder cancer cell lines: J82, T24, 253J, 5637, and BLZ-211. LBHD1 high and low expressing cells were used to investigate the migration, invasion, and proliferation of bladder cancer cells following transfection of LBHD1 with siRNA and plasmids, respectively. Our experiment showed that the degree of gene expression was positively related to the migration and invasion of the cancer cells while it had little effect on cell proliferation. Knocking down LBHD1 expression with LBHD1 siRNA significantly attenuated cell migration and invasion in cultured bladder cancer cells, and overexpressing LBHD1 with LBHD1 cDNA plasmids exacerbated cell migration and invasion. Nevertheless, a difference in cell proliferation after transfection of LBHD1 siRNA and LBHD1 cDNA plasmids was not found. Our findings suggest that LBHD1 might play a role in cell migration and invasion.
Model for Performance Improvement of Blocking Probability in GMPLS Networks
Authors: Goel Sandeep , Kaur Ranjit , Wason Amit
Published: November 2019

Generalized multiprotocol Label Switching (GMPLS) is a set of rules which is used in various layers like the Wavelength Division Multiplexing (WDM) layer, Time Division Multiplexing (TDM) layer, etc. to generalize the concepts of labels of Multiprotocol Label Switching networks. A block in call occurs when number of requests is more than the servers and waiting rooms. This call blocking is the very important parameter and can be calculated in terms of probability. There are a number of models to calculate the call blocking probability like Erlang B, Erlang C, etc. This paper suggests a novel, efficient and less – complex model which minimize the call blocking to very much extent for GMPLS networks. This model deals with the factors like number of wavelengths, number of links, traffic intensity, etc. which can help in reducing the call blocking probability and give better results. In this paper, the call-blocking probability is also compared with number of links by considering different wavelengths. A comparison of call-blocking probability of proposed model is also analysed. This paper deals with blocking probability optimization in GMPLS Networks using Fredericks approach. We have used peakedness factor from Fredericks approach in Engset’s formula for this optimization.”

Authors: Ndong Louis
Published: November 2019

The article investigates cultural transfers related to the expression of time and indications of time in the German translation of Ousmane Sembène´s novel Le mandat / Die Postanweisung (The money order). The paper points out the significance of time, not only as an important parameter of the narration in the selected novel, but also in the way it is used by the different actors, and especially by the main actor Ibrahima Dieng, in social interactions and human relations. Furthermore, I investigate in this article how expressions related to time indications that are deeply rooted in the author’s domestic culture, are translated and/or transported in the German version of Sembène’s novel.
Putting Humpty Together Again: How Reputation Regulation Fails the Charitable Sector
Authors: Phillips Susan D.
Published: November 2019

Investigations of how Oxfam Great Britain (GB) managed its safeguarding systems and handled revelations of sexual exploitation by its staff highlighted a variety of internal governance and culture issues, and a lack of transparency as it sought to protect its reputation. The current models of reputation management do not fully explain its actions, however. This article argues that five systemic factors in the environment in which nonprofits operate create undue pressures for protection of reputations and contribute to poor assessment of risks, inadequate accountability systems and limited transparency. These factors include: a stress on success and related competition for market share and pressures for growth; expectations of low overheads; challenges of governance and risk management; lack of public awareness; and regulatory gaps. Drawing on media coverage and the commissions of inquiry, the analysis shows how all of these contextual factors were at play in the Oxfam case, and suggests potential reforms.

A 119Sn Mössbauer-spectroscopic characterization of the diamagnetic birefringence material Sn2B5O9Cl
Authors: Klenner Steffen , Bönnighausen Judith , Guo Jingyu , Yang Zhihua , Pan Shilie , Pöttgen Rainer
Published: November 2019

The crystal structure of diamagnetic borate chloride Sn2B5O9Cl exhibits two crystallographically independent tin sites which both show pronounced lone-pair activity of the tin atoms. This is reflected in substantial quadrupole splitting in the 119Sn Mössbauer spectrum. The isomer shifts of 3.887(8) and 4.137(7) mm s−1 clearly indicate divalent tin. In agreement with bond valence calculations, the Sn1 atoms have a lower charge and the higher isomer shift, compatible with a higher electron density at the tin nuclei.
Parameter Analysis of CNT Yarns in Smart 3-D Braiding Composites
Authors: Li Peng , Wan Zhenkai
Published: November 2019

An important method for making smart three-dimensional (3-D) braiding composites is to use embedded carbon nanotube (CNT) yarn sensors with 3-D braiding technology. According to the braiding structure of 3-D six-direction braiding composites, the mathematical model of carrier movement of braiding machine is constructed. The method for calculating the number and length of embedded CNT yarns with intelligent composites is proposed. The characteristics of resistance changing for CNT yarns under loading are analyzed. Experiments show that the error of the length and actual length of the CNT yarn calculated by the Bezier curve is less than 1 %. When the tensile strain exceeds 2 %, the strain of the embedded CNT yarns begins to appear nonlinear. The loading and unloading of the specimen have some influence on the resistance change of the CNT yarn. After the load is unloaded, the CNT yarn will produce the residual resistance.
Using a Numerical Method for Designing an Asphalt Mix with Specific Aggregate Material Properties
Authors: Mansourkhaki Ali , Aghasi Amir
Published: November 2019

Common approaches for designing asphalt mixes mainly deal with the determination of the optimal percentage of the binder content, which is performed according to the volumetric properties, durability index, and strength of the produced asphalt. In this regard, laboratory results of asphalt mix designs, considering the changes in physical properties of the aggregates from production to the distribution of hot mix asphalt, highlight the need for fabrication of cyclic control specimens. The approach presented in this study allows the reduction of human mistakes during samples preparation, easy control of optimum binder content with respect to the probable changes in the aggregate sizes in each step of fabrication, transportation and implementation of the hot asphalt mix, and provide a uniform ultimate surface of the distributed asphalt. By adjusting the numerical values of the factors effective on the optimum binder percentage and constructing some statistical regression models in statistical package for the social sciences (SPSS), we obtained a set of linear equations that give the optimum binder percentage as a function of aggregate size, binder absorption, specific gravity of the mix, and specific surface of the materials. According to the results of the SPSS 23 analysis, the optimum binder content of the aggregates from 30 different mines was evaluated with respect to their grain size. Based on the obtained results and Marshall Laboratory test data, we extracted some relations for estimating the optimum binder content for hot mix asphalt. Using this method, the optimal binder content is determined using the results of the sieve analysis of the aggregates without the need for repetitive fabrication of asphalt specimens or spending a long time. Consequently, the optimal binder content for the 0–19-mm binder and 0–13-mm topcoat asphalts was determined with high accuracy.

Detection Limit for Ra-228 in Drinking Water by Gamma Spectrometry
Authors: Semkow Thomas M. , Khan Abdul J. , Menia Traci A. , Li Xin , Chu Liang T. , Torres Miguel A. , Bari Abdul
Published: November 2019

We derived a new formula for the detection limit (DL) of 228Ra in gamma spectrometry. We also revised the gamma-peak model and derived new formulas for the continuum background under the peak and its variance. We studied the detectability of 228Ra in drinking water using a modified gamma-spectrometry method. In this method, radium is coprecipitated with the barium sulfate carrier and then is dissolved to a 10-mL counting geometry. The chemical recovery is determined using a 133Ba tracer. We assayed 228Ra using a 911-keV gamma peak from 228Ac after reaching a secular equilibrium. Typically, 2.5 L of water is used in the analysis, and the gamma measurement lasts for 1,000 min. In this study, we measured background spectra separately for 4,000 min. Several germanium (Ge) gamma spectrometers were studied with the relative efficiencies ranging from 83 to 140 %, in shielding configurations with and without cosmic muon rejection. Detectability of 228Ra was studied in both the laboratory control samples (LCS) and method blanks (MB). For the LCS, we obtained the range of DL activities from 0.86 to 0.31 pCi/L (32 to 11 mBq/L), when shielding changed from a standard configuration to the muon-rejection configuration, respectively. For the MB samples, the range of DL activities was from 0.90 to 0.14 pCi/L (33 to 5 mBq/L), respectively. We also calculated the sample volumes sufficient to achieve the detection of 1 pCi/L (37 mBq/L). For all samples, the volume ranged from 2.25 to 0.34 L. Conversely, we calculated the minimum counting times to achieve the activity of 1 pCi/L (37 mBq/L), which ranged from 814 to 59 min. These results show that the low-background gamma spectrometry satisfied the regulatory DL for 228Ra equal to 1 pCi/L (37 mBq/L) and offered considerable improvement in detectability over a conventional gamma spectrometry.
Impact of the Detection and Quantitation Limits on the Analytical Feasibility of Measuring the European Chemicals Agency Risk Assessment Committee’s Recommendations for Occupational Exposure Limit Values for Nickel and Its Compounds in the Workplace
Authors: Verpaele Steven
Published: November 2019

In March 2018, the European Chemicals Agency, Risk Assessment Committee (RAC) published its final opinion for nickel (Ni) and its compounds. The proposed values were 0.005 mg/m3 for the respirable fraction for both Ni metal and Ni compounds and 0.03 mg/m3 for the inhalable fraction for Ni compounds. Scientific recommendations for occupational exposure limit values (OELVs) are based on the risk to health, not on the analytical capability of the method for workplace air determination. Practically, however, the sampling and analytical sensitivity and accuracy at the proposed OELVs need to be considered. The selection of a suitable measurement procedure depends on the requirements as stated in applicable consensus standards, for example, EN 482. This standard states that every procedure should operate within the range of 0.1–2 times OELV. For workplace Ni determination, 24 methods were identified. Based on the candidate methods’ limit of quantitation (LOQs), only 17% of the methods can measure as low as 10% of the recommended respirable OELV and 90% of the methods can measure as low as 10% of the proposed inhalable OELV. In addition, 19 European laboratories responded to a survey regarding the workplace air methods for Ni. Four laboratories responded with a nonworkplace air reference method, seven laboratories could not determine the respirable OELV, and one laboratory could not determine the inhalable OELV. The results of our study show that there is no consistency in the calculation and use of the LOQ, which makes it difficult for companies to comply with binding OELVs. Standards should clearly state what the LOQ values are for the specific analytes on which they act. Consensus also should be reached on the LOQ derivation and the importance of the specificity of the matrix (e.g., workplace air) in this calculation.
Treatment of Non-Detects Can Lead to Inaccurate Forensic Conclusions
Authors: Edwards Melanie , Pietari Jaana , Cook Linda , Boehm Paul
Published: November 2019

Collecting samples from a contaminated site, characterizing background, and considering potential sources are integral parts of both traditional site assessments and environmental forensic investigations, yet the objectives of these investigations differ. Whereas traditional site assessments generally aim to characterize the nature and extent of contamination and assess the resultant risks, the goal of forensic investigations is to identify contributing sources of contamination, including influences from local or regional background. Typical methods for handling non-detect (ND) results for site characterization work are less appropriate for forensic investigations because their influence on the forensic analyses and final conclusions is unpredictable. Detection limits (consistency, values, and treatment of) are of particular importance in forensic studies where presence or absence of one contaminant may be the characteristic that distinguishes different sources. Although substitution methods for handling ND results may be appropriate in the context of risk assessment, this approach may obscure the true forensic characteristics of the underlying sources and measured sample compositions if applied in a forensic investigation, ultimately resulting in erroneous conclusions about sources.

Through case studies, we demonstrate how various methods for handling detection limits can change the conclusions drawn from common forensic analyses. The effect of substituting numeric values for NDs on the results of common chemical forensics multivariate analyses is illustrated using simulated data and example soil samples from Colorado and Washington. The analyses discussed demonstrate a variety of impacts on multivariate analyses that stem only from changes in how ND results were included and illustrate the potential for inaccurate conclusions about the true forensic features within the data. Recommendations are provided for how to investigate and identify the impact of NDs on chemical forensic multivariate analyses.
Fundamentals of the ASTM International Committee D22 Practice for Determination of the Detection Limit of a Well-Behaved Analytical Method
Authors: Brisson Michael J. , Rook Harry L.
Published: November 2019

The concept of detection limits dates back to the 1960s, with the best-known treatise being Lloyd Currie’s 1968 definition of “detection limit” in terms of a “critical level.” The concept is important for scientists, policymakers, instrument manufacturers, and other stakeholders. It remains a source of controversy, however, because although the theory is based in statistics, it is applied by analytical practitioners. This is not always compatible. Over the past half-century, there have been many formulations, some developed for particular programs, and with these formulations, a cornucopia of terms and abbreviations, presenting challenges for a laboratory dealing with the requirements of different programs. Currie’s principles were solidified in the 1995 International Union of Pure and Applied Chemistry recommendations and International Organization for Standardization 11843 series. These principles have been embraced in Europe, but not in the United States. One possible reason is that the concepts focus on underlying statistics and not on practical application. The goal of ASTM Committee D22 on Air Quality is to begin with the smallest common denominator, a well-behaved air quality method and then to standardize a practice that has statistical rigor; will be understood and used by the analytical community, and, perhaps most important, will produce consistent results. Committee D22 hopes to expand on this admittedly narrow focus in the future. This paper describes fundamental concepts of the Committee D22 methodology, based on Currie’s 1968 and 1999 papers. It uses a one-sided test of significance to affirm or reject the null hypothesis (analyte not detected). Rejection of the null is used to determine a value above the mean background that represents detection of the analyte signal with a stated probability of repeatability. It evaluates all significant error sources and uses the magnitude and variance of the background and combined error to estimate the detection limit.
Limits of Detection and Quantification in Analytical Chemistry: A Brief Overview of the Currie Protocol
Authors: Rook Harry L. , Ashley Kevin
Published: November 2019

For many years in the field of chemical analysis, the concepts of and scientific foundation for the detection limit (DL) and the quantification limit (QL) were in the eyes of the beholder: that is, there was no established consensus on how to compute DL and QL for a given analytical method. Then, in 1968 (and reiterated in 1999), Lloyd Currie of the National Bureau of Standards, later renamed the National Institute of Standards and Technology, published what has become the internationally accepted scientific basis for both concepts. Currie uses statistical hypothesis theory to determine the DL, the method’s critical value, and the QL of a completely specified measurement system in analytical chemistry. Currie’s methodology has been adopted internationally by the International Union of Pure and Applied Chemistry (IUPAC) and by the International Organization for Standardization (ISO), among other international consensus standards bodies. ASTM International, however, has not yet developed a unified DL standard for the general measurement community. ASTM Committee D22 on Air Quality recently developed a draft standard practice for DL in air-quality measurements, which is based on the Currie method. Once finalized, this standard should ensure that DL computations for air measurements using ASTM standards are consistent with those made worldwide using the IUPAC and ISO standard DL methods.
On fractional Langevin equation involving two fractional orders in different intervals
Authors: Baghani Hamid , Nieto J.
Published: November 2019

In this paper, we study a nonlinear Langevin equation involving two fractional orders  α ∈ (0; 1] and β ∈ (1; 2] with initial conditions. By means of an interesting fixed point theorem, we establish sufficient conditions for the existence and uniqueness of solutions for the fractional equations. Some illustrative numerical examples are also discussed.

Published: November 2019

A class of semilinear fractional difference equations is introduced in this paper. The fixed point theorem is adopted to find stability conditions for fractional difference equations. The complete solution space is constructed and the contraction mapping is established by use of new equivalent sum equations in form of a discrete Mittag-Leffler function of two parameters. As one of the application, finite-time stability is discussed and compared. Attractivity of fractional difference equations is proved, and Mittag-Leffler stability conditions are provided. Finally, the stability results are applied to fractional discrete-time neural networks with and without delay, which show the fixed point technique’s efficiency and convenience.
On coincidence and common fixed point theorems of eight self-maps satisfying an FM-contraction condition
Authors: Zhou Mi , Liu Xiao-Lan , Secelean Adrian
Published: November 2019

In this paper, a new type of contraction for several self-mappings of a metric space, called FM-contraction, is introduced. This extends the one presented for a single map by Wardowski [Fixed points of a new type of contractive mappings in complete metric spaces, Fixed Point Theory Appl., 2012:94, 2012]. Coincidence and common fixed point of eight self mappings satisfying FM-contraction conditions are established via common limit range property without exploiting the completeness of the space or the continuity of the involved maps. Coincidence and common fixed point of eight self-maps satisfying FM-contraction conditions via the common property (E.A.) are also studied. Our results generalize, extend and improve the analogous recent results in the literature, and some examples are presented to justify the validity of our main results.

In recent years Ukraine has seen a growth in the consumption of cereal products. Wide demand from the population are rice, buckwheat, oat, corn cereals and derived cereal products, and grain products fast food or ready-to-eat (cereals, extruded cereals, expanded snacks, cereals, etc.). One of the most promising areas of research in the field of healthy nutrition is to develop products that have a multicomponent structure, including main raw materials and various nutrients, including to provide specified properties. The creation of such products is relevant, because due to the multi-component composition is achieved provide thehuman body the important nutrients in required amount. The nutrition of a modern person includes a variety of products, including complex prescription composition, and determines the appearance and development of the direction - "design" of complex multicomponent food products with desired properties In the article, the authors developed the formulations of extruded multicomponent products. In developing the composition for the production of extruded corn products, considerable attention was paid to the nutrient composition of the raw material, its change during processing and balance. A study of the nutritional value of extrudates developed and manufactured in laboratory conditions was carried out. The formulation of extruded cereal products was optimized. To determine the optimal shelf life of the developed extrudates, microbiological studies were carried out and an organoleptic assessment of the quality of the obtained products was carried out.When designing recipes, we used the linear programming method, which allowed us to obtain a product with high nutritional value, the necessary content of biologically active substances and good organoleptic properties. According to the research results, it is recommended that storage period up to 6 months at a temperature of (18 ± 20) оC and relative humidity not more than 75% in polypropylene package.

This article was migrated. The article was marked as recommended. Background:Chinese Americans are one of the fastest growing populations in the United States. However, 41% of Chinese Americans are not English proficient. Methods:In 2014, Medicine in Mandarin was established by the University of Michigan Medical School (UMMS) as a pre-clinical elective taught by a nationally certified healthcare Mandarin interpreter. A 32-hour curriculum was developed, including both didactics and interactive elements. Assessments included quizzes, standardized patient interviews, and a final exam. An evaluation was administered upon course completion, and a post-course survey was administered to graduates at least six months after course completion. Results:Between 2014 and 2017, the elective graduated 25 students, of whom 23 completed the course evaluation and 22 completed the post-course survey. Prior to the course, 9% of students felt comfortable practicing medicine in Mandarin. This increased to 78% of students post-course. When asked about subsequent clinical experiences, 82% of students reported having applied medical Mandarin skills. Overall, 96% rated the course as very good or excellent. Conclusion:A Medicine in Mandarin elective was well-received by students and improved their comfort in providing medical care in Mandarin. Additional study is warranted to examine the potential clinical impact of this course.

A lot of research has been devoted to identity documents analysis and recognition on mobile devices. However, no publicly available datasets designed for this particular problem currently exist. There are a few datasets which are useful for associated subtasks but in order to facilitate a more comprehensive scientific and technical approach to identity document recognition more specialized datasets are required. In this paper we present a Mobile Identity Document Video dataset (MIDV-500) consisting of 500 video clips for 50 different identity document types with ground truth which allows to perform research in a wide scope of document analysis problems. The paper presents characteristics of the dataset and evaluation results for existing methods of face detection, text line recognition, and document fields data extraction. Since an important feature of identity documents is their sensitiveness as they contain personal data, all source document images used in MIDV-500 are either in public domain or distributed under public copyright licenses. The main goal of this paper is to present a dataset. However, in addition and as a baseline, we present evaluation results for existing methods for face detection, text line recognition, and document data extraction, using the presented dataset.
