Published: February 2022

The aim of the present study was to study the effects of gamma radiation (Cs137) on the local variety of maize (Zea mays L.) usually cultivated at KENGE for possible track of its improvement. The approach consisted of irradiating the corn seeds at the doses ranging from 0 to 300 Gy at intervals of 100 each using the CONSERVATOME LISA I irradiator. The irradiated seeds were sown on a plot of 176.40 m2 of surface area according to a device in completely random blocks. In the field, some cultural precautions for consequent yield have been taken (weeding, ridging at the same time as weeding, mulching, and watering). Different cultivation parameters were determined such as germination rate, crown diameter, plant size and number of leaves / maize plant from one part and, from another part, the length of the cobs, the ear diameter, number of kernels/ear, 100 kernel weights and yield per plot.
From the results obtained it turned out that the dose of 100 Gy with average values such as 67% for the germination rate, 220.80 cm for the length of the plants, 1505 seeds per plant ear and 327.25 g per 100 seeds behaved well in relation to the witness and the irradiated persons. The dose of 300 Gy gave values far lower than those of 100 Gy (19%, 67.66 cm, 713 and 90.13 g). From these analyzes, it is possible to recommend an in-depth study in the improvement of local corn with the LD50 of 169.33 Gy.

Objectives: (1) To report internal measurements of thoracic vertebral bone morphology and (2) identify safe and clinically applicable surgical implant corridors in the T7-T9 thoracic vertebrae of French Bulldogs.
Study Design: Observational, cross‐sectional, descriptive study.
Sample Population: Seven client-owned French Bulldogs with normal thoracic vertebrae.
Methods: Computed tomographic (CT) studies of normal French Bulldogs were reviewed. Multiplanar reconstruction of the CT images was used to determine thoracic vertebral corridors. Corridor measurements included the width, length, insertion distance off midline, and angle off midline (sagittal) for each thoracic vertebra. One‐way analysis of variance was used to detect differences between groups.
Results: Measurements of vertebral corridor width (p>0.9848), length (p>0.8113), implant center (p>0.9282) and angle (p>0.3609) did not differ between each vertebra. The average vertebral corridor width was 4.5 ± 0.7 mm. The average corridor length was 17.2 ± 2.5 mm. The average corridor angle was 22.3 ± 1.9 °. The mean distance the proposed implant center was from the vertebral midline was 8.2 ± 1.1 mm. Inter-observer agreement of corridor length and implant center was good but poor for corridor angle and width.
Conclusion: Based on average corridor width and length, commercially available cortical screws or pins can be utilized for implants in this region of the thoracic spine. The angle of corridor trajectory from a dorsal approach seems most applicable for T7-T9.
Clinical Significance: Vertebral corridors can be measured using CT-MPR, and implant specifications and angles derived. Surgical guides can also be created to guide implant placement. This approach provides a simple and accurate method to guide the placement of thoracic vertebral implants.

Portal vein thrombosis is one of the most common complications of liver cirrhosis, the risk factors for which are still not fully understood.Purpose: to develop a prognostic model to determine the likelihood of portal vein thrombosis based on anamnestic, etiological factors, the presence of hepatocellular carcinoma, as well as parameters of CT perfusion of liver tissue.Material and methods. 43 patients with compensated liver cirrhosis (58.1% of men) and 38 patients with subcompensated liver cirrhosis (50% of men) were included in the prospective study. The age of patients in the first group was 52.56 ± 9.62 years, in the second group - 50.95 ± 9.94 years. The number of patients with 1 etiological factor of liver cirrhosis in the study groups was 62.8% and 81.5%, respectively. Type 2 diabetes mellitus was exhibited in 23.3% of patients with compensated liver cirrhosis and in 15.8% of patients with subcompensated liver cirrhosis. The diagnosis of hepatocellular carcinoma was established in 27.9% of patients with compensated liver cirrhosis and in 18.4% of patients with subcompensated liver cirrhosis. All patients, after the native study, underwent CT perfusion of the liver using a 256-slice Philips ICT apparatus. As a result of postprocessing, the values of arterial, portal, total perfusion and perfusion index of liver tissue were determined. Statistical analysis of the data was carried out using the binary logistic regression method and the construction of ROC curves.Results. A logistic stepwise multivariate analysis showed that an increase in arterial perfusion (p = 0.002) and a decrease in portal perfusion (p = 0.004) were independently associated with portal vein thrombosis in patients with compensated liver cirrhosis, and a history of primary liver cancer (p < 0.001) was a dependent factor in this model. In patients with subcompensated liver cirrhosis, a history of hepatocellular carcinoma (p < 0.001) and a decrease in portal perfusion (p = 0.001) became independent predictors of portal vein thrombosis, male gender (p = 0.029) was a dependent factor in the developed model.Conclusion. CT-perfusion of the liver makes it possible to determine predictors that can be used together with such factors as the presence of hepatocellular carcinoma and gender in the construction of prognostic models to determine the likelihood of portal vein thrombosis in patients with compensated and subcompensated liver cirrhosis. Age, etiological factor and the presence of type 2 diabetes mellitus in the developed models were not statistically significant.

The amusement rides, has a height limit for riding a rides. The regulation was made for security and safetywhen riding a rides. In dangerous amusement rides, height regulation is made with a minimum height with a high enoughnumber, the height limit can be above 130 cm. The limit makes many visitors can’t ride rides because they have less height.But even though the regulation has been made, there are still many visitors who still want to ride the amusement rides eventhough its height is insufficient. Therefore, it would be more effective if an automatic door was made that could detect theheight of the visitor's and the door would open if the visitor's had a sufficient height. This door is placed in the positionbefore the queue, so in addition to the automatic door, there is also a system of counting the number of visitors who are in thequeue. The number of queues will be displayed on the seven segment screen and if the queue is full it will be informed on theLCD. The height limit on this door is made with a minimum height of 130 cm so that the door is open. This door height andautomatic queuing system uses the Arduino Mega microcontroller and the FC-51 infrared obstacle sensor to detect visitors.Besides this door is equipped with LEDs and loudspeakers as a provider of information about the visitors of the amusementrides is allowed to enter or not due to the height of the visitor's.

Objectives:
To determine the causes for formation of nodules in 5 out of 9 women immunized with the genetically engineered vaccine against hCG.

Material and Methods:
Studies were carried out in C57BL/6 strain of mice. Vaccine was given not only by intradermal but also by intramuscular route.

Results:
Nodules were formed in mice when vaccine was given by intradermal route but not by intramuscular route. No antibodies were measurable after 1 µg of the Protein version of the vaccine. However the vaccine given at 2 µg dose (equivalent to 388 µg human dose) induced good antibody response in every mouse.

Conclusion:
Vaccine may be given by intramuscular and not by intradermal route. The dose of the vaccine for women should be at least 300 µg of the Protein version of the vaccine after priming with the DNA version of the vaccine to induce antibody response.

Тестирование и поиск ошибок в программном обеспечении является неотъемлемой частью цикла его разработки. Ошибки в программном коде несут угрозу работоспособности и безопасности программы. Для устранения последствий необходимо находить и устранять ошибки на ранних этапах разработки. Одним из методов поиска ошибок является статический анализ. В работе приведен обзор типов ошибок в коде, написанном на языках C и C++, которые способны находить инструменты статического анализа. Также приведен обзор основных методов и техник, применяемых в статическом анализе. В рамках исследования был проведен анализ возможностей статических анализаторов с открытым исходным кодом. Было выбрано несколько популярных инструментов статического анализа и база тестовых листингов кода, содержащая фрагменты программ на языках С и С++ с различными типами ошибок. На основании результатов, которые продемонстрировали статические анализаторы на тестовой базе, было сформировано представление о том, какие типы ошибок могут быть затруднительными для обнаружения исследуемыми инструментами. Среди найденных типов ошибок внимание было уделено тем, которые могут стать причиной появления уязвимости в программе. В работе предложен вариант расширения возможностей доступных на данный момент инструментов статического анализа с открытым исходным кодом для поиска небезопасного использования функции memcpy. Был разработан модуль статического анализа на основе инфраструктуры clang static analyzer, позволяющий обнаруживать выделенный тип ошибки.
