Calculation of the frequency electronic transmission factors at the passage through the polymeric polyimide composite material filled by bismuth silicate
In this paper, a theoretical evaluation of the interaction of fast electrons with a polymer polyimide composite filled with bismuth silicate was carried out, calculations were carried out for the specific energy losses of electrons and transmission coefficients. It is shown that the Bi, C, and O atoms make a greater contribution to the ionization losses, and the radiation losses are practically due only to the Bi atoms. It has been established that at the electron energies from 1 to 6 MeV, interesting from the point of view of electronic protection of equipment in outer space, the losses are mainly determined by the ionization of atoms, and not by radiation losses. It is established that for an electron energy of 6 MeV at a composite thickness of up to 0.8 cm, the transmittance by the number of electrons predominates, and at a composite thickness of more than 0.8 cm, the transmission coefficient of electrons over the energy begins to predominate. The high stability of the developed composite with respect to the flux of fast electrons is shown in the general case of their fall at different angles to the normal of the target surface.ΠΡΠΎΠ²Π΅Π΄Π΅Π½ΠΎ ΡΠ΅ΠΎΡΠ΅ΡΠΈΡΠ½Π° ΠΎΡΡΠ½ΠΊΠ° Π²Π·Π°ΡΠΌΠΎΠ΄ΡΡ ΡΠ²ΠΈΠ΄ΠΊΠΈΡ

BACKGRAUND: The treatment of girls with genital trauma is an urgent problem because of the increased frequency in cases in recent years. This study examines the treatment effectiveness in girls with various types of genital trauma.
MATERIALS AND METHODS: Case histories of 126 girls aged one to 17 years with external genital organ injuries and treated from 2016 to 2020 were studied. They included 120 (95%) patients with mechanical injuries and six (5%) girls with intravaginal electrochemical burns. The types of injuries, clinical picture, diagnostic methods, methods of surgical interventions, and treatment outcomes were studied.
RESULTS: The data obtained as a result of the analysis showed an increase in the number of injuries of the external genital organs in girls by 2.2 times, with a predominance of victims aged two to 10 years (69%). The structure of injuries was dominated by mechanical damage (95%) due to domestic and street injuries. Most injuries were localized in the external genital area, and deeper injuries accounted for 7.9%. Massive bleeding with the development of severe posthemorrhagic anemia was noted in 4.2% of cases. Surgical treatment was performed in 80.8% of cases. In cases of combined injuries with the rectum (2%), operations were performed jointly with surgeons. Mortality and postoperative complications were not observed. In six patients, one finger and five disc batteries, which caused electrochemical burns, were found and removed from the vagina. The treatment control of these injuries was performed with dynamic vaginoscopy. For more than six months, four girls had pronounced cicatricial changes.
CONCLUSION: Therapeutic tactics for mechanical injuries have shown effectiveness due to the absence of complications and a short hospital stay. The rehabilitation of patients with electrochemical burns requires further study since two-thirds of them have long-lasting cicatricial changes.ΠΠΊΡΡΠ°Π»ΡΠ½ΠΎΡΡΡ.

BACKGRAUND: The treatment of girls with genital trauma is an urgent problem because of the increased frequency in cases in recent years. This study examines the treatment effectiveness in girls with various types of genital trauma.
MATERIALS AND METHODS: Case histories of 126 girls aged one to 17 years with external genital organ injuries and treated from 2016 to 2020 were studied. They included 120 (95%) patients with mechanical injuries and six (5%) girls with intravaginal electrochemical burns. The types of injuries, clinical picture, diagnostic methods, methods of surgical interventions, and treatment outcomes were studied.
RESULTS: The data obtained as a result of the analysis showed an increase in the number of injuries of the external genital organs in girls by 2.2 times, with a predominance of victims aged two to 10 years (69%). The structure of injuries was dominated by mechanical damage (95%) due to domestic and street injuries. Most injuries were localized in the external genital area, and deeper injuries accounted for 7.9%. Massive bleeding with the development of severe posthemorrhagic anemia was noted in 4.2% of cases. Surgical treatment was performed in 80.8% of cases. In cases of combined injuries with the rectum (2%), operations were performed jointly with surgeons. Mortality and postoperative complications were not observed. In six patients, one finger and five disc batteries, which caused electrochemical burns, were found and removed from the vagina. The treatment control of these injuries was performed with dynamic vaginoscopy. For more than six months, four girls had pronounced cicatricial changes.
CONCLUSION: Therapeutic tactics for mechanical injuries have shown effectiveness due to the absence of complications and a short hospital stay. The rehabilitation of patients with electrochemical burns requires further study since two-thirds of them have long-lasting cicatricial changes.ΠΠΊΡΡΠ°Π»ΡΠ½ΠΎΡΡΡ.

A distinct tendency to an increased number of pregnancies and deliveries among young women has been observed lately. Pregnant teenagers with various types of traumas can be admitted to a non-profile pediatric surgical in-patient facility where no gynecologist is available. Purpose. The article describes a clinical case of an injury to the uterus and 33β34-week fetus in 17-year-old pregnant woman after an accidental fall on a kitchen knife. Materials and methods. The patient in a severe condition was admitted to the hospital with a knife in the anterior abdominal wall. Post-hemorrhagic anemia was diagnosed (Hb 95 g/L, RBC3.0 Ρ
1012/L). Based on urgent indications of an operating team consisting of a pediatric surgeon and an obstetrician-gynecologist, a midline laparotomy was performed. 2L of blood was removed from the cavity, the cutting edge of a knife was removed from the uterus body. No other damages were found during abdominoscopy. Cesarean section was done in the inferior segment of the uterus, an alive fetus was removed, bilateral ligation of uterine arteries was done and a hemostatic supraplacental suture was applied. A double balloon obstetric catheter was used. The uterine wound was sutured. Total blood loss was about 3 L. It was compensated with red blood cells (1385 ml) and fresh frozen plasma (2740 ml) transfusion. The removed boy had a weight of 2,300 g and 2 Apgar scores. Resuscitation activities were successful. The child was taken to the ICU and put on life support. 2 cm long injury was found in the right axillary region not penetrating into the chest. Its primary surgical debridement was done. Postoperative period in a child and mother who was taken to the maternity home went on without complications. The child was examined in a year. He developed according to the age. Conclusions. It can be possible that pediatric surgical departments are not ready for Cesarean section and elimination of possible complications when dealing with pregnant teenagers with various types of traumatic injuries requiring urgent obstetric intervention. Thatβs why itβs better when the patients are admitted to maternity homes where a pediatric surgeon is available.Π¦Π΅Π»Ρ.

Overview of methods to control the liquid distribution in distillation columns with structured packing: Improving separation efficiency
Characteristic of TiO 2 &Ag 0 nanocomposites formed via transformation of metatitanic acid and titanium (IV) isopropoxide
International audienceComposite nanoparticles TiO 2 &Ag 0 were synthesized by coprecipitation in a weakly alkaline medium in the presence of various precursors-metatitanic acid and titanium (IV) isopropoxide. Comparative study of TiO 2 &Ag 0 included analysis of morphology (CEM), phase (XRD) and chemical compositions (EDS). The formation of anatase structures was confirmed at a relatively low concentration of silver (0-8 wt.% for metatitanic acid and 0-4 wt.% for Ti (IV) isopropoxide). An increase in the Ag fraction to 8 wt% led to the appearance of the Ti 2 O 3 and -TiO 2 phases in the Ti(IV) isopropoxide system. The size distribution of primary particles is 8.3-10.6 nm (Ti(IV) isopropoxide system) and 12.3-14.0 nm (metatitanic acid system). The anatase lattice parameters decrease with Ag wt% increasing in Ti(IV) isopropoxide system and do not change for the metatitanic acid system. TG-DTA study showed the effects corresponding to the removal of structural water (210 Β°C), destruction of isopropoxide and combustion of organic matter (300-410 Β°C), crystallization of anatase (510 Β°C) and the anatase transformation into rutile phase (720-760 Β°C), but in the presence silver the anatase structure did not change to 1000 Β°C. Morphological study shows high crystallinity of both kinds of structures but less aggregative stability composites formed in the metatitanic acid solution. All type nanocomposites include four chemical elements-Ti, Ag, O, and Na as well as a small amount of various admixtures-S or Cl and K depending on precursore species. At the same time, relatively high concentration of argentum in the initial solution led to obtaining chemically pure composite nanoparticles and core&shell type structures
