Inclusion of evidence in a criminal case as a form of implementation of the state-governmental powers of the preliminary investigation and court bodies
Authors: Rossinskiy Sergey B. 
Published: November 2022

The article examines the essence of inclusion of evidence in a criminal case as one of quite common law enforcement practice of the bodies of preliminary investigation and court.
Methodologically, starting from a differentiated approach to criminal procedural algorithms for accumulation of evidentiary material, the author associates the meaning of inclusion of evidence with the need for legalization of objects and documents received by a preliminary investigation body or a court as ready-made information productes.
In this regard, the article concludes that it is impossible to understand the category of “inclusion of evidence in a criminal case” as a purely technical device, that is, there is a need for its interpretation as one of the forms of exercising discretionary powers of authorised participants in criminal proceedings predetermining the endowment of relevant objects with the legal force and the ability to be used to justify convictions or other law enforcement acts.

Authors: Wajdi Ibrahim Wasan , Talib Mosa Maha 
Published: November 2022

Background: Preterm labor and related prematurity are predisposing factors that increase perinatal morbidity and mortality. Acute phase reactants are inflammatory markers which are positive and negative reactants explained by the reaction of reactants to the subclinical infection that are commonly associated with preterm labor.
Objectives: To assess the role of acute phase reactants in pregnant women with preterm delivery.
Patients and method: A case control study conducted in Gynecological Department of Baghdad Teaching Hospital from 1st February 2021 to 30th October 2021, on one hundred pregnant women with gestational age (28weeks - 36weeks+6days) who attended outpatient clinic; fifty pregnant women with established preterm labor as case group and fifty pregnant women with no signs and symptoms of preterm labor as control group. Data was collected using structured questionnaire included demographic features, and biochemical parameters (serum ferritin (ng/ml), albumin (gm/dl), fibrinogen (mg/dl), and calcium (mg/dl) .
Results: Mean±SD serum ferritin in control group was (46.2 ± 16.2 ng/ml) while in case group (52.47 ± 11.6ng/ml) with significant difference between both groups (P=0.03), mean±SD serum albumin in control group (3.18 ± 0.31 ng/ml) while in case group (2.92 ± 0.39) with highly significant difference between both groups (P<0.001). Validity test of serum ferritin at cutoff ≥ 52.7 (ng/ml) in case group was as follows: Sensitivity (94%), specificity (90%), negative predictive value (94%), positive predictive value (90%) and the accuracy was (92%). The validity test of serum albumin at cutoff ≤ 3.06 (gm/dl) to detect the preterm labor as follows: Sensitivity (78%), specificity (86%), negative predictive value (78%), positive predictive value (83%) and the accuracy was (84%). Mean±SD serum fibrinogen in control group was (400.9 ± 38.1) while in case group was (410.7 ± 51.2) with no significant difference between both groups (P=0.1). Mean±SD serum calcium in control group was (8.1 ± 0.7) while in case group was (7.92 ± 0.5) with no significant difference between both groups (P=0.1).

Published: November 2022

BACKGROUND: People with peripheral neuropathies suffer significant sensorimotor impairment. Prescribed treatment includes the use of orthosis. However, a common obstacle to treatment efficacy is patient adherence. Given the limited information available, gathering evidence on adherence to orthotic treatment is essential. OBJECTIVE: This study aims to identify aspects that influence adherence to orthotic treatment in patients with peripheral neuropathies. METHODS: We applied a survey including items from the assistive device evaluation section of Quest 2.0 and self-developed questions to assess the importance and satisfaction of wrist-hand orthosis users. We used the principles of the Kano model to understand the nature of issues influencing adherence and prioritize opportunities for product improvement. RESULTS: User satisfaction with the ease of adjustment, weight, comfort, effectiveness, durability, dimensions, and appearance of orthoses influences treatment adherence. CONCLUSIONS: We found differences in estimating the importance of orthosis aspects from direct consultation and estimation from the satisfaction-adherence correlation. Satisfaction is an indirect measure of importance and an adequate predictor of adherence. The application of Kano’s model allows a more precise identification of the influence of orthosis attributes on adherence. This method describes relationships between aspects that are not discernible in linear models.

Published: November 2022

BACKGROUND: Pancreatic cancer is a highly lethal disease. The preoperative distinction between pancreatic serous cystic neoplasm (SCN) and mucinous cystic neoplasm (MCN) remains a clinical challenge. OBJECTIVE: The goal of this study is to provide clinicians with supportive advice and avoid overtreatment by constructing a convolutional neural network (CNN) classifier to automatically identify pancreatic cancer using computed tomography (CT) images. METHODS: We construct a CNN model using a dataset of 6,173 CT images obtained from 107 pathologically confirmed pancreatic cancer patients at Shanghai Changhai Hospital from January 2017 to February 2022. We divide CT slices into three categories namely, SCN, MCN, and no tumor, to train the DenseNet201-based CNN model with multi-head spatial attention mechanism (MSAM-DenseNet201). The attention module enhances the network’s attention to local features and effectively improves the network performance. The trained model is applied to process all CT image slices and finally realize the two categories classification of MCN and SCN patients through a joint voting strategy. RESULTS: Using a 10-fold cross validation method, this new MSAM-DenseNet201 model achieves a classification accuracy of 92.52%, a precision of 92.16%, a sensitivity of 92.16%, and a specificity of 92.86%, respectively. CONCLUSIONS: This study demonstrates the feasibility of using a deep learning network or classification model to help diagnose MCN and SCN cases. This, the new method has great potential for developing new computer-aided diagnosis systems and applying in future clinical practice.

Relevance and methodology. Meadow communities forming in various ecological regimes, participate in the biogeochemical carbon cycle, accumulating and retaining it, removing it from the atmospheric air. A significant part of the natural meadows in the old-developed region is intensively exploited and loses carbondepositing functions. The sustainable management of meadows under intensive exploitation provides for the organization of their restoration and optimal exploitation. In field and office work, the method of trial plots, ecological analytical methods with the determination of organic carbon in the composition of soil humus, the method of phytocenotic analogs, the weight method, and a number of statistical methods were used.Results. The research of the dynamics of the carbon content of above- and underground biomass, soil of three meadows types, showed a favourable effect of restoration processes on the organic carbon content of soils, the growth of biomass and productivity. The long-flooded meadows turned out to be the most responsive to restoration processes. However, the increase in the amount of aboveground and underground biomass in meadows, the productivity of meadows also increased for all types of meadows by the age of 5 years, and then decreased. The following monitoring indicators to diagnose the progress of recovery processes in meadow ecosystems are recommended: root biomass, leaf area index and content of labile organic matter. Therefore, when planning the management of meadows during restoration successions, it is necessary to provide for a moderate pasture load with 4–5 years of restoration processes. Planning the use of meadows, it is necessary to provide for a combination of sequestration and deposit processes of organic carbon, which is a way to increase or preserve the humus content of soils, preserve crop yields, and reduce CO2 emissions into the atmospheric air.

Authors: Ponazhev V. P. 
Published: November 2022

Relevance. The efficiency of primary oil flax seed production largely depends on the methods of plant selection and the creation of updated (original) seeds, which still remain complex and time consuming. The development of new, more advanced methods for selecting the initial crop material, aimed at reducing labor intensity, labor costs and speeding up work at the initial stages of seed production, is relevant and has practical significance. Methods. The object of research was the process of selection and testing of oil flax plants according to the relevant characteristics, the subject of research was typical plants and seeds obtained from them. The experiments were carried out in accordance with the methods of field experiments, as well as methodological recommendations for seed production of oil flax. The varietal quality of seeds was assessed by the method of soil control. The content of phosphorus and potassium in the soil was determined by the Kirsanov method, and the acidity of the soil was determined by the ionometric method.Results. It has been established that the method of selecting oil flax plants according to a new trait — the flowering period, compared with the accepted analogue, made it possible to increase the yield of renewed (original) seeds by 35.6%, increase their uniformity in seed weight by 8%, seed strength —by 9.1%, reduce labor costs by 31%. The method of soil control established a high level of varietal quality of seeds created using selection for a new trait. It was revealed that negative selection, which involves the removal of plants that are atypical in terms of morphological characteristics, provided, compared with the control, an increase in seed yield by 22.6%, an improvement in their morphological and physiological properties, including an increase in seed strength by 13.6%, an increase in the length of the seedling seed by 25%, as well as a reduction in labor costs by 23.5%. The results of soil testing showed that this method allowed us to obtain original material uniform in color, as well as plants with the necessary evenness in height and fiber content in the stem.

Relevance and methodology. Grain quality of crops is largely determined by the content and composition of proteins. The content of protein and amino acids in grain varies due to specific and varietal characteristics of the crop. The study of the effect of organo-mineral biological preparations on the yield and amino acid composition of grain of spring barley varieties proves to be relevant. The research was carried out in 2020–2021 in the conditions of experimental fields of the Bryansk State Agrarian University on gray forest medium loamy soil. The research object is spring barley varieties Raushan, Vladimir, Yaromir. The agricultural technique of cultivating spring barley is generally accepted for the region. There were the variants with biological preparations Geotone, Gumistim, Bioagro-PP, Bioagrogum-B, control (without treatment). The total nitrogen content in the grain was valued by the indophenol method and amino acids were assessed by capillary electrophoresis with the instrument "Kapel 105".Results. According to the results obtained, the highest grain yield of 6.82 t/ha and 7.35 t/ha of the barley varieties Vladimir and Yaromir was in the variants with Bioagro-PP, and the yield of 6.82 t/ha of the variety Raushan was in the variant with Gumistim. The application of biological preparations in barley cultivation contributed to an increase in the content of nitrogen in barley grain. It is established that the application of biological preparations contributed to an increase in the content of amino acids in the grain, including essential ones. Assessing the varietal characteristics of barley, it should be noted that the largest number of amino acids was in the grain of the variety Raushan, and the variety Yaromir had the smallest number. In the grain of Raushan the highest content of amino acids of 15.50 and 15.74 g/100 g of dry matter was recorded in the variants with Geotone and Bioagrogum-B.
