Influence of methods of post-harvest treatment of maize hybrid seeds on their quality and lon-gevity
Authors: Kyrpa M.Ya. , Filipkova N.S. 
Published: May 2023

The results on the effects of the technological operations and methods of post-harvest treatment on the maize hybrid seed quality and longevity are presented. The operations and methods included drying of wet cobs to dry consistency, separation of seeds in the cleaning, calibration and gravimetric sorting modes as well as chemical treatment (advance pre-sowing and immediate pre-sowing treatments).
The new drying method was found to depend on the harvest moisture and the speed of water evaporation from cobs. At moisture of 20.3–41.0%, drying at the optimum temperature and rapid water release were more effective, as this mode prevented seeds from germination and suppressed any activity of microorganisms. The drying temperature should be 36–40ºC at moisture of 30–32% and 40–44ºC at moisture of 20–22%.
The optimal methods and modes of separation, which ensured high germinability and yield of maize hybrid seeds after long-term storage, were defined. For seeds intended for long-term storage, the cleaning rate should be at least 80%, and fractions should be selected from this category by calibration on sieves with mesh diameters of 9, 8 and 7 mm. Gravimetric sorting increases the germinability and yield of hybrid seeds, especially of those that formed the smallest fraction (in our experiments, it came from the separation sieve with a mesh diameter of 6-5.5 mm depending on the hybrid).
Chemical treatment – seed dressing is a mandatory operation in the storage and sowing technologies for maize hybrids. It was found that chemical treatment – dressing should be carried out immediately before sowing this crop, and untreated seeds should be stored.
It was proven that, provided the optimized methods and modes of post-harvest and pre-sowing treatment, the maize hybrids could be stored for 3–4 years, with the laboratory and field germinabilities as well as yield of seeds remaining at high levels.

Issues of direct modeling effective thermal conductivity of two-component thermally conductive polyimide composite films based on polyimide thermosetting varnishes and thermally conductive powder fillers are considered.
3D-structural modeling of elementary cubic cells of polyimide composites has been performed.
Calculations of average heat fluxes and effective thermal conductivity of variants of polyimide composite films with the introduction of highly thermally conductive highly dispersed and ultradispersed powder fillers into the polyimide matrix were carried out, including those from SiO2, SiC, Al2O3, AlN, taking into account boundary and initial conditions using COMSOL MULTIPHYSICS software.
Specific recommendations are proposed for direct modeling of the thermal conductivity of environments with a complex structure and for carrying out with sufficient reliability numerical calculations of the effective thermal conductivity of polyimide composite films in order to increase their thermal conductivity from 0,12 W/(m•K) up to 1-4 W/(m•K) by changing concentration and thermal conductivity of mixtures of filler particles of micron and ultramicron sizes.

Background: The phenotypic spectrum of Fukutin-related protein ( FKRP) mutations is highly variable and comprises of limb girdle muscular dystrophy (LGMD) R9 (previously LGMD 2I) and FKRP related congenital muscular dystrophies. Objective: To identify the distinct genotype phenotype pattern in Indian patients with FKRP gene mutations. Methods: We retrospectively reviewed the case files of patients with muscular dystrophy having a genetically confirmed FKRP mutation. All patients had undergone genetic testing using next-generation sequencing. Results: Our patients included five males and four females presenting between 1.5 years and seven years of age (median age - 3 years). The initial symptom was a delayed acquisition of gross motor developmental milestones in seven patients and recurrent falls and poor sucking in one patient each. Two patients had a language delay, with both having abnormalities on the brain MRI. Macroglossia, scapular winging, and facial weakness were noted in one, three and four patients respectively. Calf muscle hypertrophy was seen in eight patients and ankle contractures in six. At the last follow-up, three patients had lost ambulation (median age - 7 years; range 6.5–9 years) and three patients had not attained independent ambulation. Creatine kinase levels ranged between 2793 and 32,396 U/L (mean 12,120 U/L). A common mutation - c.1343C>T was noted in 5 patients in our cohort. Additionally, four novel mutations were identified. Overall, six patients had an LGMD R9 phenotype, and three had a congenital muscular dystrophy phenotype. Conclusion: Patients with FKRP mutations can have varied presentations. A Duchenne-like phenotype was the most commonly encountered pattern in our cohort, with c.1343C>T being the most common mutation

Background: Variants in RYR1, the gene encoding the ryanodine receptor-1, can give rise to a wide spectrum of neuromuscular conditions. Muscle imaging abnormalities have been demonstrated in isolated cases of patients with a history of RYR1-related malignant hyperthermia (MH) susceptibility. Objective: To provide insights into the type and prevalence of muscle ultrasound abnormalities and muscle hypertrophy in patients carrying gain-of-function RYR1 variants associated with MH susceptibility and to contribute to delineating the wider phenotype, optimizing the diagnostic work-up and care for MH susceptible patients. Methods: We performed a prospective cross-sectional observational muscle ultrasound study in patients with a history of RYR1-related MH susceptibility ( n = 40). Study procedures included a standardized history of neuromuscular symptoms and a muscle ultrasound assessment. Muscle ultrasound images were analyzed using a quantitative and qualitative approach and compared to reference values and subsequently subjected to a screening protocol for neuromuscular disorders. Results: A total of 15 (38%) patients had an abnormal muscle ultrasound result, 4 (10%) had a borderline muscle ultrasound screening result, and 21 (53%) had a normal muscle ultrasound screening result. The proportion of symptomatic patients with an abnormal result (11 of 24; 46%) was not significantly higher compared to the proportion of asymptomatic patients with an abnormal ultrasound result (4 of 16; 25%) ( P = 0.182). The mean z-scores of the biceps brachii (z = 1.45; P < 0.001), biceps femoris (z = 0.43; P = 0.002), deltoid (z = 0.31; P = 0.009), trapezius (z = 0.38; P = 0.010) and the sum of all muscles (z = 0.40; P < 0.001) were significantly higher compared to 0, indicating hypertrophy. Conclusions: Patients with RYR1 variants resulting in MH susceptibility often have muscle ultrasound abnormalities. Frequently observed muscle ultrasound abnormalities include muscle hypertrophy and increased echogenicity.
THE MAIN PRINCIPLES OF DESIGNING PUBLIC SPACES IN GERMANY ON THE EXAMPLE OF THE CITY OF HANNOVER
Authors: Melnyk Mariia 
Published: May 2023

In Germany, public space and its use are thought to be full of conflicts: festivalization vs. everyday quality, advertising vs. urban design, commerce vs. culture, drivers vs. strollers, demonstrators vs. tourists, private use vs. general accessibility, spontaneous, temporary appropriation vs. permanent order, and design
The often conflicting expectations – also of women and men or old and young people – about public space are an expression of the increasingly heterogeneous nature of urban society. In terms of design, the pendulum swings between nostalgic kitsch, cool modern design and aesthetic neglect.
In recent years, the pressure and overload of private and public advertising, road and information signs, retail and restaurant furniture and telecommunications equipment have increased. The generally accepted indicator, the agreement about what quality of form is in public space, seems to be largely lost.
Too often only the city center is seen as a public space in need of planning and political attention. Main roads or district and district centers are lost from sight, let alone commercial areas. Demographic changes, a smaller, older and brighter urban population make new demands on public space, as a place where different cultures and increasingly differentiated lifestyles meet, as a place for the integration of urban society.
So there is a need for action. It is not about uniform rules for the use and design of public spaces, nor about the illusion of ideal and consistent planning. Rather, it is about criteria of social and aesthetic quality, about what is appropriate in each city and each district, which should be developed and discussed in dialogue with residents, users and the public.
Investigation of thixotropy of underwater silty soils
Authors: Sukach Mykhailo , Komotska Svitlana 
Published: May 2023

In the natural state, thixotropic phenomena in soils most often occur under external loads of a dynamic nature: earthquakes, vibrations from moving vehicles, working machines and mechanisms. Data on the study of soil thixotropy indicate that under dynamic load to reduce the strength and go into a liquid state can be dispersed soils of different types, genesis and age. The influence of dynamic loading is especially significant in the case of poorly compacted and water-saturated sandy and clay soils.
At dynamic loading there can be both consolidation of soil and accordingly increase in its durability, and decrease in durability. More often it is necessary to face processes of decrease in durability and thinning of soils at dynamic influence. The most studied processes occurring in water-saturated sands. The state of liquefaction during vibration occurs due to the destruction of contacts between individual grains, the strength of sandy soil drops to almost zero. After removing the vibration load, the grains of sand under the influence of their own weight move down, causing compression of the liquid phase. The more sands contain fine particles and organic matter, the longer they retain a liquid state, the slower the squeezing of water and compaction. The possibility of thinning sandy soils is determined not so much by natural porosity, but by the stress of the soil and the nature of vibration.
