Steponavičienė, Aušra, Dainius Steponavičius, Algirdas Raila, and Aurelija Kemzūraitė. "MODELLING THE OZONE PENETRATION IN A GRAIN LAYER / OZONO SKVERBTIES GRŪDŲ SLUOKSNYJE MODELIAVIMAS." Journal of Environmental Engineering and Landscape Management 20, no. 4 (November 22, 2012): 292–300. http://dx.doi.org/10.3846/16486897.2011.645826.
Full textAbstract:
Studies of grain drying with ozone-air mixture were carried out to detect the ozone penetration patterns through the grain mound of various moisture content (14.6 ≤ w 0 ≤ 23.0%) at different ozone concentrations (500 ≤ C 0 ≤ 1250 ppb) in the supplied air. The ozone penetration through the grain layer depends on the initial ozone concentration in the supplied air, ozonation time, velocity of the supplied air, height of the grain mound, initial grain moisture content and mycobiotic contamination of grain surface. It was determined that in a 60 cm height of the grain layer ozone is first recorded after 12 h, and at 105 cm – only after 34 h at w 0 = 19.0%, C 0 = 500 ppb. If the initial concentration of ozone is higher, it is first recorded sooner. Ozone penetration through the grain layer with higher moisture level is slower, and ozone reaction with grain surface and microflora present on it is longer. Hypothesis about the adequacy of the model (how it reflects the real process) has been verified by calculating reproduction and adequacy variance. The mathematical model could be applied for prediction of the course of grain ozonation process. Santrauka Grūdų džiovinimo ozono ir oro mišiniu tyrimai atlikti siekiant išaiškinti ozono skverbties per skirtingo drėgnio grūdų sampilą dėsningumus (14,6 ≤ w 0 ≤ 23,0%), esant skirtingoms ozono koncentracijoms (500 ≤ C 0 ≤ 1250 ppb) tiekiamame ore. Ozono skverbtis grūdų sluoksnyje priklauso nuo pradinės ozono koncentracijos tiekiamame ore, ozonavimo trukmės, tiekiamo oro greičio, grūdų sampilo aukščio, pradinio grūdų drėgnio ir jų paviršiaus mikobiotinio užterštumo. 60 cm grūdų sluoksnio aukštyje ozonas pradėtas fiksuoti po 12 h, o 105 cm – tik po 34 h, kai w 0 = 19,0%, C 0 = 500 ppb. Padidinus pradinę ozono koncentraciją, ozonas pradedamas fiksuoti greičiau. Ozonuojant drėgnesnius grūdus, ozonas per jų sluoksnį skverbiasi lėčiau, vyksta ilgesnė jo reakcija su grūdų paviršiumi ir ant jų esančia mikroflora. Hipotezė apie modelio adekvatumą (kaip jis atspindi realų procesą) buvo patikrinta apskaičiavus reprodukcijos ir adekvatumo dispersijas. Sudarytas matematinis modelis gali būti taikomas grūdų ozonavimo procesui prognozuoti.

Monitoring of atmospheric air at an urban background station in the city of Varna, Bulgaria between 2007 and 2014 to evaluate the levels of the secondary pollutants О3 and its precursors – NO, NO2, NMHC and CO. Annual, monthly and diurnal variations were studied. The results show that О3 and the precursors do not exceed the norms that threaten human health. As compared with the start of the monitoring, the О3 concentrations have risen from 32.22 to 52.04 µg/m3 and the differences have high statistical significance (0.025 ≤ Р ≤ 0.05). The maximum concentrations of the secondary pollutant О3 are achieved several hours after the peak precursor levels. Measures are proposed for reduction of the emissions of the О3 precursors with the aim to reduce the concentrations of the secondary pollutant in the lower atmosphere.

Full textAbstract:
Changes and distribution of ozone concentration in the area of high‐voltage transmission lines were investigated. The investigation on ozone concentration changes was performed with application of two methods: by using an ozone analyser and by passive samplers. The role of an accumulating element was performed by a glass‐fiber filter installed in a passive sampler. It was impregnated with a 1.2‐di(4‐pyridyl)ethylene and acetate acid solution. The impact of meteorological parameters on the passive sampler efficiency and ozone concentration variation is discussed. These parameters can increase or decrease the real concentration value in comparison with the concentration obtained by co‐located continuously running ozone analyser. Ozone concentration near high‐voltage lines varied from 10 to 51 ppb, and “background” ozone concentration changed from 3 to 50 ppb during the investigation period. The average concentrations were 28.1 and 27.5 ppb near the lines and “background” during the whole experiment period. The wind direction from “background” location to the high‐voltage lines prevailed during the experiment. The obtained results by different methods demonstrated good agreement; the difference between ozone concentrations was from 1 to 24% for individual cases. Santrauka Tirta ozono koncentracijos kitimas ir pasiskirstymas ties aukštosios įtampos perdavimo linijomis. Ozono koncentracija matuota dviem metodais – ozono analizatoriumi ir pasyviaisiais kaupikliais. Pasyviajame kaupiklyje kaip kaupiantysis elementas buvo naudojamas stiklo pluošto filtras, impregnuotas 1,2-di(4-pyridyl)etileno ir acetatinės rūgšties tirpalu. Vėjo greitis, vėjo kryptis, UV spinduliuotė, temperatūra ir santykinė oro drėgmė gali turėti įtakos pasyviųjų kaupiklių efektyvumui bei ozono koncentracijos pasiskirstymui, todėl kartu tirti ir meteorologiniai parametrai (temperatūra, santykinė oro drėgmė, vėjo greitis ir kryptis). Tyrimo laikotarpiu ozono koncentracija ties aukštosios įtampos tiekimo linijomis kito nuo 10 iki 51 ppb, o nutolusioje per 222 m vietovėje, kuri buvo traktuojama kaip foninė, – nuo 3 iki 50 ppb. Išmatuota vidutinė ozono koncentracija foninėje vietoje buvo 27,5 ppb, o ties linijomis – 28,1 ppb. Eksperimento metu vyravo pietryčių krypties vėjas, t. y. nuo foninės vietos – aukštosios įtampos tiekimo linijų link. Nustatant ozono koncentraciją skirtingais metodais duomenys pakankamai sutapo, pavieniais atvejais nesutapimas svyravo nuo 1 iki 24 %. Резюме Исследовалось изменение и распределение концентрации озона в районе высоковольтных линий электропередач. Концентрация озона измерялась двумя методами: анализаторами озона УФ-поглощения непрерывного действия и с использованием пассивных сорбентов. В качестве сорбента использовался фильтр из стекловолокна, пропитанный 1,2-ди(4-пиридил)этиленом и уксусной кислотой. Параллельно непрерывно измерялась температура и относительная влажность воздуха, скорость и направление ветра. Исследования показали, что концентрация озона в течение эксперимента изменялась в интервале от 10 до 51 ррb у линии и от 3 до 50 ррb на «фоновой» точке, удаленной от линий электропередач на расстояние 222 м. В течение эксперимента почти половину времени преобладал боковой ветер по отношению к высоковольтным линиям со стороны фоновой точки. Средние измеренные концентрации озона составляли 27,5 ррb на «фоновой» точке и 28,1 ррb – у линий. Результаты измерения концентрации озона как анализаторами непрерывного действия, так и по методике с использованием пассивных сорбентов показали хорошее совпадение: разница составляла 2–15% и лишь в отдельных случаях 24%.

After several years of scientific research and accurate clinical practice, the oxygen-ozone therapy continues to represent a method full of prospects and new opportunities. On this basis we present an updated review on basic mechanisms through which the ozone acts. Ozone, a molecule notable for its heterodoxy and atypicalness, has been regarded with suspicious for a long time since it was a possible generator of free radicals and correlated pathologies, but it is important distinguishing between the oxidative damage from free radicals, characterized by irreversible chemical modifications of the molecular target, and the physiological effects from free radicals (redox signaling), characterized on the other hand, by reversible chemical and selective alterations, which are potentially suitable to become an active part in the various metabolic regulation mechanisms, with positive effects on several pathologies.

Ozone enters into chemical reaction with many organic compounds. Ozone is a very strong oxidant. It oxidizes most of the elements to higher oxides. In the oxidation reaction by ozone activity second only to fluorine, its oxide and free radicals. It is formed from oxygen by absorbing heat in this case, and, conversely, when the expansion goes into oxygen, giving off heat. The main method of obtaining ozone for practical purposes is electrosynthesis. In industrial conditions for using ozone and corona discharge barrier. Ozonizers corona discharge can significantly increase the efficiency of ozone by reducing capital and operating costs for the process equipment and ozonation. Research shows that ozone air ozonator pulsed mode increases the resistance of animals to the action of microorganisms factor. In animals and poultry in industrial production often develop diseases caused by pathogens factor. These diseases mainly occurring symptom of lesions of the respiratory and digestive systems. In many countries today conducted research using ozone, and the results of these studies are published in the course of scientific-metric database. For normal growing animals, especially young animals, premises should be thoroughly disinfected. Disinfection is required for all technological facilities as livestock and poultry. Experimentally found that ozone has a bactericidal effect (for example, test cultures E. coli) on different surfaces (wood, Petri dish) considering its concentration and exposure. The results of influence of different concentrations of ozone in ozonair mixture is fed into the container of the Petri dish, and time impact on survival of microorganisms provides a fairly accurate prediction of the results of impact parameters ozonation.

Abstract: Candida albicans is one of the pathogenic fungal species which causes oral infections. One of the methods to minimize the risk of fungal infection is by application of asepsis procedure through gargling with antiseptics. Ozone has high oxidative properties, therefore, it is considered as an antiseptic agent. Plasma Study Center of Diponegoro University has developed an ozone generator machine which opens up an opportunity to identify ozone properties as an antiseptic in controlling the number of fungal colonies, especially Candida albicans. This study was aimed to identify the effects of ozone exposure on the number of fungal colonies of Candida albicans. This was a laboratory experimental study with one-group pretest-posttest design. A total of 32 samples of Candida albicans suspensions were divided into two groups (16 each). Group 1 was not treated with ozonation, while group 2 were ozonated. Then, the two groups were cultured in SDA media using the spread plate method and were incubated for 48 hours. The data were obtained by calculating the number of fungal colonies growing in SDA media. The Wilcoxon test obtained a p-value <0.05, meaning that there were differences in the colony number of Candida albicans before and after ozonation. In conclusion, ozone exposure has a significant effect on the number of fungal colonies of Candida albicans. Further studies are needed adding variables or parameters.

Wood industry based on sengon (Falcataria moluccana) material has developed rapidly and cause the huge wastes. Lignocellulosic materials, such as sengon sawdust, offer a great potential as cheap and abundant feedstock for biofuels production. Ozone oxidation pretreatment was carried out on sengon wastes to improve fermentable sugar production by enzymatic saccharification. Sengon wood (SW), sengon media (SM), and sengon spent media (SMM), that was waste of media after mushroom cultivation, treated with ozone for different treatment time were enzymatically saccharified. Then the decrease of hydrolysis weight, reducing sugar yield, and monosaccharide yields were determined. Ozone treatment resulted in Klason lignin degradation in the all samples, resulting in the improvement of subsequent enzymatic saccharification. Ozone treatment with the duration more than 30 min was not suitable for SMM sample. Glucose yield after saccharification from the ozone-treated sample for 60 min was the highest among all samples in SW and SM treated, but for SMM it was 30 min. Based on these results, we concluded that mushroom cultivation can reduce the ozone time treatment and it is an effective treatment to improve sugar yield by enzymatic saccharification of sengon wastes. Gabungan Pra-perlakuan Ozonolisis dan Budidaya Jamur Sebelum Sakarifikasi Enzimatis Serbuk Kayu Sengon (Falcataria moluccana)IntisariIndustri kayu berbahan baku kayu sengon (Falcataria moluccana) saat ini tengah berkembang dengan sangat pesat dan hal ini menyebabkan timbulnya banyak limbah kayu sengon. Materi lignosellulosa, seperti limbah serbuk kayu sengon, merupakan potensi yang sangat baik sebagai bahan baku bio-fuel karena murah dan banyak tersedia. Praperlakuan dengan oksidasi ozon pada limbah kayu sengon dilakukan untuk meningkatkan produksi gula reduksi melalui proses sakarifikasi enzimatis. Serbuk sengon (SW), media sengon (SM), dan limbah media sengon (SMM), yang merupakan sisa dari media budidaya jamur, diberi perlakuan dengan ozon pada berbagai lama waktu perlakuan. Sampel yang sudah diberi perlakuan ozon tersebut kemudian dianalisis kandungan kimianya dan di-sakarifikasi secara enzimatis. Selanjutnya diukur laju hidrolisis, kadar gula pereduksi, dan kadar monosakarida. Perlakuan dengan ozon menyebabkan degradasi kadar Klason lignin di semua sampel, sehingga mengakibatkan peningkatan kemampuan sakarifikasi dari enzim. Perlakuan ozon dengan lama waktu lebih dari 30 menit tidak sesuai untuk sampel SMM. Kadar glukosa hasil sakarifikasi yang tinggi diperoleh dari sampel SW dan SM yang diberi perlakuan ozon selama 60 menit, serta SMM yang diberi perlakuan 30 menit. Berdasarkan hasil ini, dapat disimpulkan bahwa perlakuan jamur dapat mengurangi lama waktu perlakuan ozon dan praperlakuan efektif untuk meningkatkan kadar gula reduksi yang dihasilkan dari sakarifikasi enzimatis limbah kayu sengon.

W artykule przedstawiono wyniki badań, których celem było określenie, w jakim stopniu ozon wykorzystywany do dezynfekcji pomieszczeń wpływa na możliwość ujawnienia metodą DFO śladów linii papilarnych na podłożach papierowych. Gwałtowny wzrost zachorowani na COVID-19 skierował uwagę na dezynfekcję pomieszczeń technikami, które zapewniają bezpieczeństwo ich użytkownikom. Istotne staje się także zapewnienie bezpieczeństwa osobom otrzymującym przesyłki, na których mogą się znajdować patogeny. Ich inaktywacja powinna być dokonana w taki sposób, aby można było przeprowadzić badania pozwalające na identyfikację nadawcy, co jest istotne z punktu widzenia kryminalistyki. Ozonowanie jest techniką dezynfekcji wykorzystywaną od wielu lat, szczególnie do uzdatniania wody, w przemyśle spożywczym. Eksperymenty wykonano w pomieszczeniach o kubaturze ok. 20 m3 przy użyciu generatora ozonu dostępnego na rynku. Uzyskiwane stężenie gazowego ozonu nie przekraczało 10 ppm. Przeprowadzone badania potwierdziły, że ślady linii papilarnych pozostawione na papierze kserograficznym umieszczonym w pomieszczeniu poddanym ozonowaniu w stężeniu nieprzekraczającym 10 ppm nie ulegają zniszczeniu i z powodzeniem mogą być ujawnione metodą DFO. The effect of ozone disinfection of rooms on the efficacy of revealing dactyloscopic traces on the surface of the paper using the DFO method during the SARS-CoV-2 pandemic The article presents the results of research aimed at determining the extent to which ozone used for disinfecting rooms affects the possibility of developing fingerprints on paper using the DFO method. A sudden increase in COVID-19 cases has placed the focus on disinfection techniques for user safety. It is also becoming important to ensure the safety of parcels addressed to various recipients by inactivating pathogens, while maintaining the possibility of examination that can identify the sender, which is important from the point of view of forensics. Ozonation is a disinfection technique that has been used for many years, in particular for water treatment or in the food industry. The experiments were carried out in rooms with a cubature of approx. 20 m3 using an ozone generator available on the market. The obtained ozone gas concentration did not exceed 10 ppm. The conducted research confirmed that the traces of fingerprints left on xerographic paper placed in a room subjected to ozonation in a concentration not exceeding 10 ppm are not damaged and can be successfully developed with the DFO method.

Susu kambing mengandung komponen gizi yang tinggi dan dibutuhkan oleh manusia, namun mempunyai sifat mudah rusak akibat cemaran bakteri sehingga dikenal sebagai perishable food. Penelitian ini bertujuan untuk mengaplikasikan ozon dalam susu dengan tujuan untuk menganalisis total bakteri dalam susu, serta pengaruhnya terhadap komponen protein, lemak dan laktosa. Ozon dengan kadar 3 ppm digunakan dalam penelitian ini dan diaplikasikan pada susu dengan lama pemaparan 0, 3, 6, dan 9 menit. Pengamatan dilakukan pada akhir penelitian dan dianalisis dalam hal total bakteri, protein, lemak dan laktosa. Hasil penelitian menunjukkan bahwa jumlah bakteri dalam susu semakin menurun (p<0,01) seiring lamanya waktu pemaparan ozon. Penurunan bakteri mencapai 0,45; 0,95; dan 1,42 log CFU/ml masing-masing dengan lama ozonisasi 3, 6 dan 9 menit. Terdapat hubungan yang sangat kuat (r=0,92; R2= 0,99; p<0,0001) antara lama waktu pemaparan ozon dengan penurunan jumlah bakteri dalam susu yang mengikuti fungsi y= 7E+06e-0,364x. Tingkat lama pemaparan ozon tidak secara nyata mempengaruhi kadar protein susu, namun secara signifikan menyebabkan penurunan pada kadar lemak (p<0,01) dan laktosa susu (p<0,05) pada lama ozonisasi 6 menit. Kesimpulan dari penelitian ini bahwa ozon dapat digunakan untuk meningkatkan kualitas mikrobiologi susu segar dan menjaga kandungan nutrisi susu.The Effects of Ozone Exposure Time on Microbiological Quality and Nutrient Contents of Ettawa Crossbred Goat MilkAbstractGoat milk is known to have high nutritional components that plays an important role in human health. However, it has a short shelf-life and highly perishable. Milk is an excellent medium for the growth of microorganism, particularly bacterial pathogens that cause spoilage and disease in consumers. This research aims to apply ozone in milk, then to analyse bacterial count as well as their effects on protein, fat and lactose. Sample of raw milk were collected before and after ozone gas exposure at 3 ppm for 0, 3, 6 and 9 minutes. The assays were carried out using a randomized experimental design and the results were statistically evaluated by ANOVA. As results, bacterial counts in milk decreased (p<0.01) with the length of ozonation time. The decline in bacterial count reached 0.45; 0.95; and 1.42 log CFU/ml with 3, 6 and 9 minutes ozonation, respectively. There was a very strong relationship (r = 0.92; R2= 0.99; p<0.0001) between the length of time of ozone exposure and the decrease in the number of bacteria in milk with following equation y = 7E+06e-0,364x.The duration of ozone exposure did not affect much in milk protein, but significantly caused a decrease in milk fat (p<0.01) and lactose concentrations (p<0.05) at 6 minutes of ozonation. It can be concluded that, ozone could be used to improve the microbiological quality of fresh milk and maintain its nutrient content.

Full textAbstract:
Ozone has been widely used in the food industry as an effective antimicrobial agent. In this study the possibilities of using ozone in table olive preservation was investigated for the first time. For this purpose, the Domat variety of table olives was processed according to the Spanish style and treated with aqueous ozone for 5, 10, and 20 minutes at 0.5, 1, 2 and 4 ppm. The effects of ozonation on the microbiological, physical and sensory characteristics of the table olives were evaluated during the storage period (up to 180 days). The pH, color and firmness of the ozone treated table olives showed higher stability. Statistically significant reductions in the total bacteria and yeast/mould counts were obtained (p < 0.05). Enterobacteriaceae and Escherichia coli were not found in the samples. After 60 days of storage the control samples (ozone untreated olives) obtained low values for sensory analysis, and did not meet market requirements. The results indicate that treating green table olive with ozon (1 ppm concentration) for 10 min in aqueous form reduces the microbial population without any negative effects on the firmness, color (L*, a* b*) or sensory attributes of the table olives.

Abstract Ozone is a natural and artificial chemical compound of Earth’s atmosphere. O3 is an absorbent of ultraviolet and infrared radiation and has strong oxidative properties. In the stratosphere the ozone layer protects the planet’s surface from dangerous UV radiation, its indirect effect on plant organisms is positive so stratospheric ozone can be called “good” ozone. The depletion of the ozone layer, as a result of atmosphere pollution, described as an ozone “hole” is causing UVB radiation enhanced level on Earth’s surface. The genetic, cytological, physiological and morphological reaction of prolonged UVB exposure in plants is twofold: it damages plants and simultaneously plants protect themselves and repair their injuries. The ozone in the troposphere originates from natural sources and is also a secondary pollutant, formed in photochemical reactions, leading to “smog” and ozone “spots” occurrence. As a strong oxidant, O3 is directly toxic to plants and can be recognized as “bad” ozone. Ozone is also classified as a “greenhouse” gas, participating in global warming. It is difficult to value the impact of O3 as a “greenhouse” gas on plants. The combined effect of O3 changes in the stratosphere and troposphere on plants can be estimated as loss in crop yield and in productivity of natural ecosystems

Abstract A study was carried out to determine the influence of ozon treatment on the shelf-life of poultry meat. The following doses of gaseous ozone were used: 0 ppm for 0 min, 10 ppm for 1 min, 10 ppm for 5 min, 10 ppm for 15 min, 100 ppm for 1 min, 100 ppm for 5 min, and 100 ppm for15 min. Treated and untreated samples were stored at 4°C for a maximum of 3 days and microbiologically examined on the 1st, 2nd and 3rd day of cold storage. The textural properties and water content were also analyzed. The present study showed that the most desirable color change was recorded after the 3rd day of storage, on the samples treated with gaseous ozone of 10 ppm for 15 min. Regardless of exposure time and the gas dose used, ozone has been shown to effectively reduce meat hardness. Although the analyzes performed had non-significant effects on water content and microbiological load during post-treatment storage at 4 °C, our findings confirmed the effectiveness of the ozone gas used on extending shelf life of the examined poultry meat by influencing their texture profile and color parameters.

Full textAbstract:
Ozon is considered an environmentally friendly, low-cost antimicrobial treatment and an effective alternative to chemical pesticides. Ozonated water in the form of droplets and mist has been used in two concentrations (4 and 2 mg/L) against three biomasses (102, 104, and 106 CFU/mL) of phytopathogenic bacteria Erwinia amylovora, Pseudomonas syringae, and Agrobacterium tumefaciens and fungus Botrytis cinerea that infest a wide range of crops worldwide and pose a threat to global food production. Regardless of concentration, ozone dissolved in water showed a pronounced inhibitory effect on phytopathogenic bacteria when applied in the form of droplets. However, the effect was only detected when the bacterial load was not higher than 104 CFU/mL, indicating the necessity to treat the crops and plant materials when the bacterial load is still manageable. Unlike bacterial phytopathogens, B. cinerea was the most susceptible to treatment with aqueous ozone, regardless of the applied biomass, ozone concentration, or type of application. Total removal of high biomass of B. cinerea was achieved even with the lowest ozonated water concentration thus underlying the power of ozone in treating this particular fungal contamination.

Acquired antibiotic resistance represents one of the main restrictions to an effective antibacterial chemotherapy. The continuous growth of the phenomenon draws a therapeutical problem to eradicate infections. Ozone presents known properties, such as antibacterial, antiviral, anti-fungal, anti-inflammatory, analgesic, immunomodulation, and reactivation of microcirculation. Oxygen-ozone therapy has no collateral effects, it is minimally invasive, it is not painful and it does not cause allergic or toxic reactions or drug-drug interactions. Therefore, oxygen-ozone therapy has proved to be useful to control and run out infections in patients with a noted antimicrobial resistant pathology. We are evaluating the best protocol to treat these pathologies, to obtain the most efficient therapeutical response.

This paper describes the ozonation process in yarn dyed wastewater using continuous stirred tank reactor with the objective to study the kinetic of COD degradation at various volumetric flow rate (30, 50, 70 ml/min) and ozone concentration (2.70 %, 4.25%, 5.86 % mol/mol). The wastewater which was collected from a yarn dying process located in Surabaya area was pretreated by electrocoagulation prior to ozonation process. The electrocoagulation process was carried out to reduce the color intensity and total suspended solid. The pretreated wastewater was then processed using ozonation for 2.5 hours. The result showed that at various concentration of ozone, maximum COD removal was 90.78% which was achieved at 5.86 %mol/mol of Ozon and volumetric flow rate 50 ml/min. It was found that the degradation process followed the pseudo-first order kinetic model. The obtained pseudo-first order rate constants for volumetric rate of 50 mil/min were 0.0307 min-1, 0.0419 min-1 and 0.053 min-1 for ozon concentration of 2.70 %, 4.25%, 5.86 % mol/mol respectively. The residence time were 41 minutes, 31 minutes and 23 minutes for ozone concentration of 2.70 %, 4.25%, 5.86 % mol/mol respectively. These findings offers an alternative treatment for wastewater containing dyes.

Some ozone therapists reported side effects during the O-MAHT, but the origin has not been described yet. We investigated the effect of blood drawing velocity during O-MAHT to see its effects on the vascular system and symptomatology. We administered O-MAHT to 11 subjects, and we interleaved fast and slow reinfusions. We monitored cerebral macrocirculation with transcranial Doppler (TCD) and tissue microcirculation with near-infrared spectroscopy (NIRS). Annoying symptoms appeared just during the fast reinfusion periods. NIRS and TCD parameters revealed vasoconstriction during fast reinfusion and improved metabolism during slow reinfusion. Overall, our investigation well discriminated fast from slow reinfusion velocity.

The indoor ozone and nitrogen oxides concentration depends on their outdoor concentrations, indoor sources and their removal rates on the surfaces. The paper presents experimental data of the of ozone and nitrogen oxide removal in the chamber. The ambient conditions were simulated by four combination of different temperature and relative humidity levels. The impact of temperature (T = 20 °C and T = 30 °C) and relative humidity (RH = 24% and RH = 80%) on the deposition velocity was estimated. It was found that the ozone removal in the chamber was influenced more by temperature, and the nitrogen oxides removal was affected more by relative air humidity. The results showed that higher ambient temperature (T = 30 °C) increased the ozone removal rate in the chamber 3 times on an average, and high relative humidity (RH = 80%) increased the NOx removal rate 4.5 times in comparison with the initial conditions (T = 20 °C; RH = 24%). The obtained deposition velocities varied in the range (0.0045–0.0137) cm s−1 for ozone and in the range (0.002-0.0129) cm s −1 for nitrogen dioxide. Santrauka Ozono ir azoto oksidų koncentracija patalpose priklauso nuo šių teršalų koncentracijos lauke, jų šaltinių patalpose ir šių teršalų suirimo greičio ant skirtingų paviršių. Darbe nagrinėjamas ozono ir azoto oksidų suirimas eksperimentinėje kameroje. Skirtingos mikroklimatinės sąlygos buvo sukuriamos naudojant keturių skirtingų temperatūrų ir santykinių oro drėgnių lygių derinius. Vertinta temperatūros (T = 20 °C ir T = 30 °C) ir santykinio drėgnio (RH = 24 % ir RH = 80 %) įtaka tiriamų teršalų suirimui. Nustatyta, kad ozono suirimui daugiau įtakos turėjo temperatūra, o NOX irimui – santykinis oro drėgnis. Nustatyta, kad aukštesnė aplinkos temperatūra (T = 30 °C) paspartina ozono suirimą kameroje vidutiniškai tris kartus, o didelis santykinis drėgnis (RH = 80 %) paspartina NOX suirimą 4,5 karto, lyginant su pradinėmis sąlygomis (T = 20 °C; RH = 24 %). Eksperimento metu ozono suirimo greitis kito nuo 0,0045 iki 0,0137 cm s−1, o azoto oksidų – nuo 0,002 iki 0,0129 cm s−1. Резюме Концентрации озона и оксидов азота в помещениях зависят от их концентрации в открытом воздухе, источникахвнутри помещений и скорости их распада на поверхностях. В статье представлены экспериментальные данные по распаду озона и оксидов азота в камере при разных микроклиматических условиях, созданных с применением четырех комбинаций температур и относительной влажности. Оценивалось воздействие температуры (T = 20 °С и Т = 30 °С) и относительной влажности воздуха (RH = 24% и RH = 80%) на скорость осаждения. Было обнаружено,что на распад озона в камере большее влияние оказывает температура, а на распад оксидов азота – относительная влажность воздуха. Результаты показали, что при повышении температуры окружающей среды (T = 30 °С) увеличилась скорость распада озона в камере в 3 раза по сравнению со средней, а при высокой относительной влажности (RH = 80%) увеличилась скорость распада NOx в 4,5 раза по сравнению с начальными условиями (T = 20 °C; RH = 24%). Полученные для озона скорости осаждения варьировали в пределах (0,0045−0,0137) cм с-1, а для оксида азота – в пределах (0,002−0,0129) cм с-1.

Full textAbstract:
Treatment of real yarn dyed wastewater using hybrid electrocoagulation (EC)-ozonation process has been carried out to solve the non biodegradable wastewater. The work aimed to treat the real yarn dyed wastewater under different ozone concentration and agitation speed and to estimate the kinetic parameter of ozonation. The effect of ozone concentration, agitation speed were studied to give the best performance of color and chemical oxygen demand (COD) removal. The result indicated 38.12% of COD removal and 92.53% of color removal using EC with Al/Al electrodes for 10 minutes. The effluent was pumped to ozonation process for further COD removal. The result showed that 1 mg/L ozon was needed to destroy 4.73 mg/L COD. At ozonation process, the COD removal was 87.4% using 5.8% mol ozone at 400 rpm for 60 minutes. The kinetic parameter was estimated based on the experimental data. The reaction rate constant was 173.5 cm3/(g sec).

Placental insufficiency, as well as its complication intrauterine chronic fetal hypoxia, is one of the important problems of modern perinatology. At the same time, its numbers have been increasing in recent years. Purpose - Evaluation of the effect of ozone therapy on the blood circulation of the mother and fetus, fetoplacental blood flow and the degree of adaptation of the fetus to hypoxia according to the results of cardiotocography, ultrasound and dopplerometry. Material and methods: 38 pregnant women who applied to the Department of Obstetrics and Gynecology of Clinic No. 1 of the Samara State Medical University with fetoplacental insufficiency were divided into two groups according to the type of treatment: patients who received complex treatment with ozone therapy, and patients who received standard medical procedures. Results: about a third of women in each group had a combined extragenital pathology. Women in both groups were statistically comparable when compared in terms of general clinical characteristics, basic anthropometric data, extragenital diseases and reproductive history. The most common complications of childbirth were premature rupture of amniotic fluid (4 in the 1st group - 22.2% and 5-25% in the 2nd group) and acute fetal hypoxia (3-16.7% and 3-15%). Conclusion: Thus, the indicators of maternal-fetal circulation, fetoplacental circulation in women in the ozone therapy group were more positive than in the 2nd group, and the level of fetal adaptability to hypoxia was higher.

Full textAbstract:
Medication-related osteonecrosis of the jaw (MRONJ), an adverse reaction to medication, has been reported since 2002, at first in cancer patients with bone metastases treated intravenously with pamidronate or zoledronate, and later in patients taking oral bisphosphonate for the treatment of osteoporosis. Several cases of MRONJ have also been described in patients treated with antiangiogenic drugs with a so-called biological target (bevacizumab, sunitinib, sorafenib). Oxygen/ozone therapy for MRONJ treatment represents a possible and efficient alternative to the two main therapeutic approaches currently in use, antibiotic therapy and surgery. Since 2010, I have diagnosed 51 MRONJ cases at ASST Fatebenefratelli-Sacco. Subsequently and following the approval of the Ethics Committee (2015), patients with MRONJ level 1 and 2 have been included in an experimental protocol with oxygen/ozone therapy: Treatment of bisphosphonate-related osteonecrosis of the jaw with oxygen/ozone therapy and surgical debridement with piezoelectric scalpel. The study is currently running and up to now six out of fourteen patients healed perfectly. Among these six, four spontaneously or almost spontaneously have expelled the necrotic part without undergoing surgery. In three cases, there was only an improvement in symptoms. Five patients are currently being treated. Because of its antiseptic properties, oxygen ozone therapy reduced the effects of infection and inflammation, while the bio stimulant action of this therapy promoted the demarcation of bone sequestration and soft tissue healing.

Abstract. Ozone profiles from balloon soundings as well as SAGEII ozone profiles were used to detect anomalous large ozone concentrations of ozone in the lower stratosphere. These secondary ozone maxima are found to be the result of differential advection of ozone-poor and ozone-rich air associated with Rossby wave breaking events. The frequency and intensity of secondary ozone maxima and their geographical distribution is presented. The occurrence and amplitude of ozone secondary maxima is connected to ozone variability and trend at Uccle and account for a large part of the total ozone and lower stratospheric ozone variability.
