Study of the operating modes of the high voltage power source for barrier type discharge excitation
Authors: Barakhoev A. L. , Tikhon O. I. , Tuboltsev V. V.
Published: February 2021

The issues related to the features of operation and modes setting of a high-voltage switching power source based on a sequential autonomous resonant inverter with reverse diodes used to excite an atmospheric pressure barrier type discharge are discussed in the article. It is indicated that the characteristic features of the autonomous resonant inverters operation are the occurrence of damped voltage fluctuations in the LC circuit of the inverter, as well as the dependence of the output alternating voltage on the ratio of the inverter operating frequency (thyristor switching frequency) to the natural resonant frequency of the LC circuit. Depending on this ratio, the inverter can operate in discontinuous, boundary and continuous current mode. The amplitude and shape of the inverter output voltage were controlled using a 1:1000 voltage divider with a C1-65A oscilloscope. The shape of the gate trigger pulses was obtained using a C1-167 oscilloscope. It is established that when the gate trigger pulses are asymmetrical relative to each other due to the operation features of the step-up transformers, the value of the alternating high-voltage at the inverter output is insufficient to excite the atmospheric pressure barrier type discharge. In the case of the gate trigger pulses symmetry, the output voltage of the inverter stage reaches the values required for the breakdown of the dielectric medium. Oscillograms of the inverter output voltage while adjusting its operating frequency are obtained. It is shown that the amplitude value of the voltage at the gas-discharge load increases as the operating frequency of the inverter increases. For the gate trigger pulses frequency of 250 Hz the value of the inverter output voltage amplitude was 3.4 kV, for 460 Hz – 4.0 kV, and for 550 Hz – 4.2 kV.

Mycotoxins are secondary metabolites produced by molds, mainly from the genera Fusarium, Aspergillus, Penicillium. They can contaminate food and have a harmful effect on human health. Most mycotoxins are thermostable, that is, they can persist during processing and cooking. The presence of mycotoxins in food can cause harmful effects, ranging from acute intoxication and ending with pathologies of chronic exposure (such as carcinogenic, mutagenic, teratogenic) in humans and animals. T-2 toxin is the strongest immunosuppressant, which in turn predisposes to the development of infectious diseases and leads to a decrease in productivity, which entails significant economic losses. The International Agency for Research on Cancer classifies zearalenone as a class 2A carcinogen. Therefore, the inclusion of binding agents, or enterosorbents, in the diet is given considerable attention as a strategy to reduce the bioavailability of mycotoxins and the effects of contaminated feed and food. A study of the adsorption capacity of bentonites of the Biklyansk and Tarn-Var deposits, the zeolite of the Main deposit, and in vitro halloysite nanotubes with respect to T-2 toxin and zearalenone showed that it is halloysite that has the best sorption rates (85.8 and 86.0%) and, in the future, may be used to combat mycotoxicosis of animals, birds, and, in the food chain, humans. With an increase in the pH of the medium from 2 to 8, the desorption of mycotoxins with the lowest rates for halloysite at 0.7 ± 0.04% for zearalenone and 3.5 ± 0.1% for T-2 toxin was observed in all studied adsorbents. The data obtained make halloysite nanotubes very interesting for further studies of other mycotoxins and their combinations, as well as its comprehensive study as a means of reducing the toxic load on the body of farm animals and birds.

Published: February 2021

The article presents the results of studies on the influence of methods of basic soil cultivation and fertilizer rates on the content of available forms of nitrogen, phosphorus and potassium. Experiments were laid in 2012–2018 on chernozem heavy loamy soils typical for most farms in the Ulyanovsk region. The purpose of our research was to determine the influence of the methods of basic soil cultivation and the doses of mineral fertilizers on the nutritional regime with the continuous and local placement of crop residues. The following methods of soil cultivation were studied: 1. Moldboard – (plowing by 20–22 cm PLN-4-35) control; 2. Mouldboardless – (SibIME stands for 20–22 cm), 3. Shallow comb-cultivator – (OP-3S for 10–12 cm), 4. Shallow mulching tillage – (OPO-4.25 for 10–12 cm), 5. Without the main autumn tillage, 6. Peeling with a stubble spreader – (OP-3S by 6–8 cm), 7. Ridge-curling – (OPP-3S with soil deepening up to 30–32 cm). Against the background of treatments for crop rotation, fertilizers were applied in doses of N0P0K0; N30P30K30; N60P60K60. It was found that, against a natural background, the best nitrifying ability was possessed by ridge cultivation with soil deepening, at which the weighted average value of the nitrate nitrogen content was 3.94 mg/100 g, which is 37% more than at zero, by 45% at shallow and 57–58% for conventional moldboard and moldless processing. Plowing improved the conditions for phosphorus and potassium nutrition of plants by 14–27% and 6–11% in comparison with other treatments. When N30P30K30 и N60P60K60 were introduced into the soil, the content of nitrate nitrogen increased by 48% and 84%, phosphorus and potassium by 6% and 17% compared to the non-fertilized background.

In cows of the Kalmyk breed, a chemical compound is released inside – hydrochloric acid. She, together with the gastric enzyme pepsin, breaks down the food received from the external environment into the stomach into the smallest elements that can be absorbed through the digestive glands of the stomach into the blood. Amino acids, sugars, fatty acids, fat and water-soluble vitamins, all of them, rush into the bloodstream, but the minerals, before leaving the bloodstream, it is in the stomach that they have time to bind together with gastric hydrochloric acid. The result of this chemical reaction will be, – chemical resistant chlorine compounds. In theory, this should be the end of it, but no, since chemical chloride salts are a nutrient medium for the growth of a special acid-resistant fungus inside the stomach. It is from its fungal structures that an antibacterial substance is released, a bright red color, similar to the color of the arterial blood of mammals. Having a bright red color, the antibiotic has been invisible to the human eye for many millennia. Red blood is a red antibiotic. The antibacterial substance suppresses all microflora entering the blood from the external environment, making it bactericidal resistant to microbes. Laboratory and practical research, carried out jointly with the 4th year students of the specialty "Veterinary Medicine", made it possible to understand the whole mechanism of the digestion process of the animal's body, evaluate its role in the life of Kalmyk cows and, based on this, try to outline a plan for the isolation of substance in pure crystalline form. Kalmyk cows have a strong endurance to destructive adverse environmental factors (cold, hunger) and a fairly strong immunity to pathogenic bacterial microflora, which allows us to conclude about the important properties of the antibacterial substance produced inside their stomachs. A lot of work remains to be done to prove the significance and importance of finding hydrochloric acid and an antibiotic, a bright red color, inside living mammalian bodies in the arid area of southern Russia.

The article presents the results of assessing the safety of the new drug "MT-6" in an acute experiment on white mice. Experiments to assess acute toxicity were carried out in three series of experiments with intragastric, subcutaneous and intramuscular routes of administration in duplicate. The drug was administered intragastrically once after a 12-hour fasting diet in doses from 5500 to 10000 mg/kg in a volume of 0.5 ml per mouse; subcutaneously – in the dose range from 2000 to 6800 mg/kg in a volume of 0.5 ml per mouse; intramuscularly – in doses from 2000 to 6800 mg/kg in a volume of 0.25 ml per mouse. Control animals were injected with sterile isotonic sodium chloride solution in the same volumes and by the same methods. During the first day after the administration of the drug, the experimental animals were monitored continuously, then for 14 days – 2 times a day. On the basis of toxicometric data obtained during the experiment, the parameters of acute toxicity of the drug "MT-6" were established: with intragastric administration LD50 7828.5 mg/kg, with subcutaneous administration LD50 4994.1 mg/kg, with intramuscular LD50 3841.9 mg/kg. Based on this, it was concluded that the investigated drug belongs to GOST 12.1.007-76 to the 4th hazard class – low-toxic substances; according to Hodge and Sterner (1943) to the 5th hazard class – practically non-toxic substances; according to Sidorov K.K. (1977) – to the 6th class of hazard – relatively harmless substances.

Historyczne ruiny – między doktryną konserwatorską, a społeczną akceptacją
Authors: Siwek Andrzej
Published: February 2021

W ujęciu doktrynalnym ruina jest postrzegana jako pełnoprawny zabytek, o autonomicznych wartościach. Natomiast charakter wysoce polemiczny z doktryną i teorią ma praktyka wyrażająca się w konkretnych ingerencjach w substancję zabytkową i otoczenie zabytku. Można powiedzieć, że cały okres powojenny, to okres afirmacji, pochwały odbudowy. Hasło odbudowy zakorzeniło się, jako pozytywne i twórcze. Dla realizacji koncepcji doktrynalnej ochrony ruin celowe jest przywrócenie społecznej umiejętności postrzegania piękna ruin historycznych, jako znaków w krajobrazie. Celowe jest edukowanie społeczności na ile ruiny bez własnej funkcji użytkowej mogą być jednak użyteczne, jako atrakcja regionalna, magnes przyciągający turystów i budzący wyobraźnię. To duże wyzwanie dla specjalistów z zakresu ochrony dóbr kultury, którzy nie tylko powinni dogłębnie poznawać doktryny konserwatorskie, rozumieć istotę zabytku, ale także zaznajamiać się z technikami informacyjnymi, edukacyjnymi i negocjacyjnymi, by móc mieć wpływ na podejmowane decyzje o losach kolejnych zabytków, w tym szczególnie ruin historycznych.
Zastosowanie drewna klejonego w konstrukcji budynków wysokościowych, na przykładzie realizacji z krajów zachodnich
Authors: Dmitruk Michał
Published: February 2021

Z architekturą nowoczesnych, wysokich i wysokościowych budynków z XX i początków XXI wieku kojarzone są przede wszystkim takie materiały jak stal, szkło i beton. Wraz z rozwojem technologii, coraz popularniejsze w krajach zachodnich staje się stosowanie materiałów pochodzenia roślinnego, takich jak drewno klejone. Wykorzystanie drewna jako materiału konstrukcyjnego przynosi wiele korzyści zarówno ekonomicznych, technologicznych jak i użytkowych. Jest to budulec bardziej elastyczny, lżejszy i często wytrzymalszy niż konstrukcje powszechnie stosowane. Dzięki technologii klejenia krzyżowego lub warstwowego, budynki są w stanie uzyskać znaczne wysokości, przy zachowaniu odpowiednich parametrów wytrzymałościowych. Materiał ten okazuje się być łatwiejszy w transporcie, a przy odpowiednim przygotowaniu prefabrykowanych elementów, również przyspiesza procesy budowlane, ułatwiając montaż. Jest to również materiał ekologiczny. Przy odpowiednio zaplanowanej gospodarce leśnej, jest w stanie zapewnić zrównoważone zużycie budulca, jednocześnie minimalizując koszt dla środowiska naturalnego, m.in. obniżając emisję CO2. Główną przeszkodą w zastosowaniu wspomnianej technologii na szerszą skalę, są liczne obostrzenia prawne, dotyczące wytrzymałości i odporności ogniowej. Przytaczane w poniższym artykule badania oraz przykłady realizacji, pokazują jednak iż drewno klejone jest w stanie zachować odpowiednie parametry, zapewniając trwałość konstrukcji i bezpieczeństwo użytkownikom obiektu.

W artykule przedstawiono zagadnienia dotyczące projektowania ogrodów edukacyjnych na przykładzie szkoły podstawowej i przedszkola. Myślą przewodnią koncepcji zagospodarowania ogrodu sensoryczno-edukacyjnego było stworzenie miejsca przyjaznego dzieciom i dostosowanego do potrzeb różnych grup wiekowych. Zaprojektowane założenie tworzy jedną całość kompozycyjną, mimo że obejmuje teren dwóch placówek. Ich powiązanie wynika z bliskiego sąsiedztwa obiektów oraz zbliżonych form edukacyjnych, ponieważ uczęszczają do nich dzieci w wieku przedszkolnym i wczesnoszkolnym. W aranżowanej przestrzeni zaproponowano wyspy połączone mostami, pomiędzy którymi przepływają rzeki. W wydzielonych zielenią wnętrzach zaplanowano różnorodne urządzenia, które pozwalają realizować tematykę sensoryczną i edukacyjną. Uwzględniono wiele czynników kształtujących dziecięcą świadomość ekologiczną oraz zabawy wspomagające rozwój dzieci. Na ich potrzeby opracowano urozmaicony program użytkowy. Realizacja zaprezentowanej koncepcji ożywi przestrzeń ogrodową wokół placówek i pozwoli na zwiększenie atrakcyjności oferty dydaktycznej. Otoczenie przyrodnicze i elementy jego zagospodarowania będą wszechstronnie stymulować rozwój dzieci uczęszczających do przedszkola i szkoły.
PRZEKSZTAŁCENIA OBSZARÓW LEŚNYCH DAWNEJ PUSZCZY OSIECKIEJ W XIX WIEKU
Authors: Szkołut Piotr
Published: February 2021

Historycznie Puszczą Osiecką nazywane były rozległe kompleksy leśne rozciągające się na prawym brzegu Wisły na południe od Warszawy. Za czasów I Rzeczpospolitej obszar ten  był intensywnie eksploatowany. Jednocześnie jako Lasy Królewskie podlegał ochronie. Mapy z początku XIX w. potwierdzają istnienie tych dużych kompleksów leśnych. Dopiero w XIX w. lasy znacząco się zmniejszyły głównie za sprawą prowadzonej gospodarki, rozbudowy osadnictwa i rozwoju infrastruktury drogowej. Zmiany te ukształtowały współczesny krajobraz okolic Osiecka.

A construção civil tem sido responsável por grandes avanços no que tange comodidade, praticidade do homem e da sociedade como um todo. Porém, em meio a tanta modernidade um rastro notório de degradação ambiental tem preocupado nossa sociedade. As chamadas construções em terra são uma alternativa viável, uma vez que une a viabilidade técnica à econômica sem esquecer seu respeito ao meio ambiente. O uso do adobe como exemplo dessa prática teve seu auge no passado, sendo substituído pelos materiais de construção ditos convencionais, porém estudos apresentam o adobe como método técnico e economicamente viável. Várias qualidades são inerentes ao seu uso, como por exemplo, baixo consumo de energia, facilidade para obtenção da matéria prima e conforto térmico e acústico. Através de ensaios de flexão verificou-se que o adobe quando bem confeccionado, tem suas propriedades semelhantes às dos materiais convencionais.

A aplicação de nitrogênio (N) associada ao uso de corretivos da acidez do solo pode melhorar o crescimento da cana-de-açúcar em sistemas altamente produtivos. Portanto, objetivou-se avaliar a altura, número de perfilhos, de colmos e diâmetro aos quatro, nove e doze meses da quarta soqueira da cana-de-açúcar, em função de doses de N na ausência e na presença de silício (Si). O experimento foi realizado em campo, na área experimental da UNESP - Câmpus de Jaboticabal-SP. O solo da área experimental foi classificado como Latossolo Vermelho Distrófico. O delineamento experimental utilizado foi em blocos casualizados, em esquema fatorial 5 x 2, sendo cinco doses de nitrogênio (0; 40; 80; 120 e 160 kg ha-1 de N) e dois materiais corretivos, a escória e o calcário, com quatro repetições. Para estabelecer as doses de nitrogênio, tomou-se como padrão a dose 120 kg ha-1 de N, indicada para a cana-soca, com meta de produtividade maior que 100 t ha-1 no estado de São Paulo. O trabalho foi realizado na quarta soqueira da cana-de-açúcar utilizando a variedade RB 855156. Durante a condução do experimento foram determinados, a altura, número de perfilhos e colmos e diâmetro da cana-de-açúcar. A adubação nitrogenada, associada ao uso de corretivos, promoveu melhorias nas variáveis de crescimento da quarta soqueira cana-de-açúcar.

Published: February 2021

Primary congenital bladder diverticulum is a rare cause of Urinary Tract Infection (UTI). The term bladder diverticulum is
usually reserved for the nding of large herniation of bladder urothelium through muscularis propria of the bladder wall.
Typically, congenital bladder diverticula are found in smooth walled bladders and are not associated with signicant trabeculation on cystoscopic
examination.Congenital bladder diverticula have been noted in association with a number of congenital syndromes including Menkes syndrome,
Williams syndrome, Ehler-Danlos syndrome and fetal alcohol syndrome.We present a case of Primary congenital bladder diverticulum as a rare
cause of UTI in a 4year old male child who was surgically treated.
DISSEMINATED TALAROMYCOSIS IN HIV/AIDS - A CASE REPORT
Authors: Shrutiraaj Kumar Anand , Das Parijat , Ranjan Manish
Published: February 2021

Talaromyces marneffei (previously Penicillium marneffei), a dimorphic fungus distributed widely in nature, is an
emerging pathogen associated with high mortality and morbidity. It infects individuals with some form of underlying
immune-deciency like HIV, malignancy, transplant-recipients, autoimmune diseases, prolonged steroid therapy etc. Although it's prevalence
among HIV/AIDS patients has reduced with the widespread use of Anti-Retroviral Therapy (ART), yet due to increase in patients with other
immune decient states and improved diagnostic modalities, its overall prevalence has increased. It is remarkably and specically seen in patients
who are native to or have visited South-east Asia, eastern India or southern China. Few disseminated T. marneffei infections have been reported
from India. We report a case of disseminated T. marneffei in a HIV patient with profound immune-deciency. This case highlights the importance
of considering it as an important differential in cases of patients with characteristic skin lesions having underlying immune deciency belonging
to a specic geographical area.

Authors: Kumar Abhijeet , Kumar Arpit
Published: February 2021

The study ameliorates the feasibility of IR
thermometer, and to introduce a novel design with upgraded applications
& functions. The custom compact device (shape illustrates a “Badge”)
measures the surface temperature of a body and received data processed through
a microcontroller (AtMega328P). The device functions in a way that if there is
any thermal change from ambient temperature (D-1 m), the mode is activated and
triggers a pre-defined alert. For distance measuring, it measures the intensity
of IR radiation emitted by a body from a particular direction. It also reads
the temperature when it comes across a body. It will provide an optimum
way in the primary healthcare instrumentation and helpful for noncontact,
quick, and accurate measurement of moving and high temperature body.
The outcome of colposcopy in women attending with persistent postcoital bleeding and negative HPV-DNA test
Authors: Bayrak Mehmet , Ozan Hakan
Published: February 2021

Objective: Women with postcoital bleeding (PCB) are recommended to be evaluated by colposcopy even if cytology is negative. Human papillomavirus (HPV) testing increases the detection of cervical intraepithelial neoplasia or worse compared to the Pap smear test. We aimed to determine the incidence of cervical pathology among women with persistent PCB with a negative Pap smear or HPV-DNA test. Our study, therefore, questions the place of HPV DNA test in women with PCB.

Material and Methods: The clinical data of 212 women with persistent PCB and negative cytology or negative HPV DNA test referred to colposcopy, between January 2010 and June 2019, were retrospectively evaluated.

Results: Among the 212 PCB patients, 161 (75.9%) were cytology negative and 51 (24.1%) were HPV DNA test (n=40) or co-test (n=11)  (negative for HPV DNA test and cytology) negative. There were no cases of invasive cancer. The women referred with negative cytology were more likely than those with negative HPV DNA to have CIN (21/161 (13%),  1/51 (1.9%) p=0.042. Seven women (4.3%) were diagnosed with high-grade cervical dysplasia in the negative cytology group. None of the patients in the HPV DNA negative group was diagnosed with high-grade cervical dysplasia.

Conclusion: Our data show that a normal Pap smear cytology in women with PCB does not rule out the possibility of  HSIL. HPV DNA testing is a useful triage test to determine if colposcopy referral is required in the context of post-coital bleeding with negative smear test.
