Human activities significantly contribute to worldwide spread of phytopathological adversities. Pathogen-related food losses are today responsible for a reduction in quantity and quality of yield and decrease value and financial returns. As a result, “early detection” in combination with “fast, accurate, and cheap” diagnostics have also become the new mantra in plant pathology, especially for emerging diseases or challenging pathogens that spread thanks to asymptomatic individuals with subtle initial symptoms but are then difficult to face. Furthermore, in a globalized market sensitive to epidemics, innovative tools suitable for field-use represent the new frontier with respect to diagnostic laboratories, ensuring that the instruments and techniques used are suitable for the operational contexts. In this framework, portable systems and interconnection with Internet of Things (IoT) play a pivotal role. Here we review innovative diagnostic methods based on nanotechnologies and new perspectives concerning information and communication technology (ICT) in agriculture, resulting in an improvement in agricultural and rural development and in the ability to revolutionize the concept of “preventive actions”, making the difference in fighting against phytopathogens, all over the world.

Одной из важнейших проблем качества винопродукции является ее стабильность, обеспеченная научно обоснованными методами диагностики и приемами технологической обработки с целью предотвращения возникновения дестабилизации. Причиной кристаллообразования является нарушение ионного равновесия под влиянием изменений концентрации катионов и анионов, наличием в системе стимуляторов и ингибиторов этого процесса. Одним из тестов на склонность к кристаллическим помутнениям вин является показатель «температура насыщения», который рассчитывают по разнице электропроводности до и после добавления битартрата калия (Т(КНТar)). Целью работы являлось выявление взаимосвязи между компонентным составом вина и его физико-химическими свойствами, выраженными рН и Т(КНТar). Объектами исследований были белые и красные столовые сухие виноматериалы и вина. В образцах были определены рН, температура насыщения битартратом калия, содержание ионов калия, винной кислоты и ее форм. Объем выборки составил 83 образца. В результате исследования было установлено, что стабильные белые вина характеризовались значениями Т(КНТar) в интервале 10,9-13,5 С, красные вина - 14,4-16,8 С. Выявлена и математически описана взаимосвязь между показаниями теста кристаллической дестабилизации вина и содержанием участников процесса, которую обусловливает массовая концентрация битартрат-ионов, зависящая от величины рН и содержания винной кислоты. Результаты будут использованы для усовершенствования системы диагностики вин при оценке их склонности к кристаллической калиевой дестабилизации.Stability is an important element of the quality of wine and must be enabled by science-based diagnostic methods and treatment technologies with the view to prevent destablization. Crystal formation is caused by ionic imbalances as affected by changes in cation and anion levels and the presence of promotors or inhibitors of this process in the system. Potassium bitartrate saturation temperature (Т(КНТar)) is an index to be relied on while testing wines for liability to crystal haze, and is calculated by the difference in the conductivity measurements prior to and after the addition of potassium bitartrate. The study was aimed to reveal an interrelationship between the componential composition of wine and its physico-chemical characteristics in terms of рН и Т(КНТar). Red and white dry table wines and wine materials were used as objects of research. The sample number was formed by a total of 83 samples in which pH, saturation temperature Т(КНТar) and levels of ions of potassium, tartaric acid and its forms were measured. The Т(КНТar) values of stable white wines varied within 10.9-13.5С, and the Т(КНТar) values of stable red wines ranged from 14.4 to 16.8С. An interrelationship between the data derived from the test for crystalline destabilization of wine and the levels of the agents of the process was revealed and mathematically described. This interrelationship is determined by mass concentration of bitartrate ions which depends on pH values and the levels of tartaric acid. The results obtained will be used to improve the diagnostics system of wines in testing for liability to potassium crystalline destabilization.

The paper discusses the problem of “competition” between the image and the articulated language/text. The problem as such is historical and it reflects the change between the language based communication (including the radio era) and the mainly image based communication.  Opposing to those who equate the image construction in the information and communication technology with the impoverishment of meanings and necessity and ability of logical/rational discourse, the arguments of these two positions are analysed.   The paper mentions the difference between representation, image and idea, analyses some arguments related to the logical articulation of words in texts, and to the specific imagistic manner of communication, and concludes that the text and image are complimentary, and that their worth depends on the meanings they transmit and the quality of meanings/values they transmit. In this respect, the diminishing of preoccupations, of ability and time for logical articulation of the reference to the world means the decline of man. At the same time, the theory highlighted in the paper does not counter the “bad” image to the “good” text (and certainly, nor vice versa), but the measure in their use according to the scale of goals and means which people must have.

Abstract The author of the two-part article about evaluating reflex sympathetic dystrophy (RSD) responds to criticisms that a percentage impairment score may not adequately reflect the disability of an individual with RSD. The author highlights the importance of recognizing the difference between impairment and disability in the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides): impairment is the loss, loss of use, or derangement of any body part, system, or function; disability is a decrease in or the loss or absence of the capacity to meet personal, social, or occupational demands or to meet statutory or regulatory requirements because of an impairment. The disparity between impairment and disability can be encountered in diverse clinical scenarios. For example, a person's ability to resume occupational activities following a major cardiac event depends on medical, social, and psychological factors, but nonmedical factors appear to present the greatest impediment and many persons do not resume work despite significant improvements in functional capacity. A key requirement according to the AMA Guides is objective documentation, and the author agrees that when physicians consider the disability evaluation of people, more issues than those relating to the percentage loss of function should be considered. More study of the relationships among impairment, disability, and quality of life in patients with RSD are required.

Selection Of

The construction and selection of a suitable bijective function, that is, substitution, is now becoming an important applied task, particularly for building block encryption systems. Many articles have suggested using different approaches to determining the quality of substitution, but most of them are highly computationally complex. The solution of this problem will significantly expand the range of methods for constructing and analyzing scheme in information protection systems. The purpose of research is to find easily measurable characteristics of substitutions, allowing to evaluate their quality, and also measures of the proximity of a particular substitutions to a random one, or its distance from it. For this purpose, several characteristics were proposed in this work: difference and polynomial, and their mathematical expectation was found, as well as variance for the difference characteristic. This allows us to make a conclusion about its quality by comparing the result of calculating the characteristic for a particular substitution with the calculated mathematical expectation. From a computational point of view, the thesises of the article are of exceptional interest due to the simplicity of the algorithm for quantifying the quality of bijective function substitutions. By its nature, the operation of calculating the difference characteristic carries out a simple summation of integer terms in a fixed and small range. Such an operation, both in the modern and in the prospective element base, is embedded in the logic of a wide range of functional elements, especially when implementing computational actions in the optical range, or on other carriers related to the field of nanotechnology.

AIM: to compare multiparametric endorectal ultrasound (ERUS) and enhanced imaging colonoscopy in the diagnosis of early colorectal cancer.PATIENTS AND METHODS: the study included 78 patients with epithelial rectal tumor. All the patients underwent multiparametric ERUS and colonoscopy with examination by narrow beam imaging (NBI) at optical magnification. All the patients were operated.RESULTS: a morphological examination removed specimens revealed adenomas in 48 cases, in 19 specimens – adenocarcinomas in situ and T1, and in 11 specimens – adenocarcinomas with invasion of the muscle layer or deeper. When calculating the accuracy indicators of diagnostic methods for groups of patients with adenoma, Tis-T1 adenocarcinoma, and T2-T3 adenocarcinoma, the difference in the sensitivity and specificity of the methods in none of the presented groups did not reach the level of statistical significance (p>0.05).ROC analysis showed that ultrasound has a prognostic value comparable to colonoscopy. The area difference was 0.013 (p=0.85).CONCLUSION: endoscopy and ultrasound have similar value in the diagnosis of malignant transformation of rectal adenomas.

The purpose of research: to improve the technology of growing flax in the Western region of Ukraine on the basis of the introduction of systems for minimizing tillage, which will increase the yield of trusts and seeds. Research methods: field, laboratory, visual and comparative calculation method. Research results: Field experiments included the study of three tillage systems (traditional, canning and mulching) and determining their impact on growth and development and yields of trusts and flax seeds. The traditional tillage system included the following operations: plowing with a reversible plow to a depth of 27 cm, cultivation with simultaneous harrowing and pre-sowing tillage. The conservation system is based on deep shelfless loosening of the soil and provided for chiseling to a depth of 40 cm, disking to a depth of 15 cm, cultivation with simultaneous harrowing, pre-sowing tillage. During the implementation of the mulching system, disking to a depth of 15 cm, cultivation with simultaneous harrowing and pre-sowing tillage with a combined unit was carried out. Tillage implements and machines were used to perform tillage operations: disc harrow BDVP-3,6, reversible plow PON-5/4, chisel PCh-3, cultivator KPSP-4, pre-sowing tillage unit LK-4. The SZ-3,6 ASTPA grain seeder was used for sowing long flax of the Kamenyar variety. Simultaneously with the sowing of flax seeds, local application of mineral fertilizers (nitroammophoska 2 c/ha) was carried out. The application of conservation tillage allows to obtain the yield of flax trust at the level of 3,5 t/ha, which is 0,4 t/ha (12.9 %) more than from the area of traditional tillage and 0,7 t/ha (25 %) in comparison with mulching. In the area with canning treatment, the seed yield was the highest and amounted to 0,64 t/ha. The difference between this option and traditional and mulching tillage reaches 0,06 t/ha (10,3 %) and 0.10 t/ha (18.5 %), respectively. Conclusions. Preservation tillage, which is based on shelf-free tillage to a depth of 40 cm and disking to a depth of 15 cm has a positive effect on plant growth and development, yield and quality of flax.
