Opis:
Thermal decomposition of HFC-134a at 900–1000 K was investigated using a laboratory scale reactor. The experimental results indicate that the lower initial HFC-134a concentration and higher reaction temperature could enhance HFC-134a decomposition efficiency. Based on the results of measurements, it seems that the reaction order is around 1. Its activation energy (Ea) and the frequency factor (A) in the investigated temperature range are 300.5 kJ·mol–1 and 2.96×1014, respectively. The results demonstrate that 99.9% destruction efficiency could be achieved when HFC-134a/LPG is below 0.5 and the excess air ratio – above 0.6.

Opis:
Состояние печени и желчевыводящих путей существенно влияет на функциональную деятельность многих органов и систем, включая характер течения патологических процессов в полости рта. Нарушения антимикробной функции печени могут вызвать развитие или обострить течение стоматологического заболевания, в патогенезе которого решающую роль играет микробный фактор. Цель исследования – изучение влияния на эффективность лечения больных хроническим катаральным гингивитом, развившемся на фоне гепато-билиарной патологии (ГБП), с применением гепатопротектора кверцетина (биофлавоноид, Р-витаминактивное соединение, обладает сильным антиоксидантным, противовоспалительным, адаптогенным действием) и пребиотика инулина, который, стимулируя рост пробиотической микрофлоры, устраняет явления дисбиоза, как правило, развивающиеся при патологии печени. Под наблюдением находилось 85 больных в возрасте 25-49 лет (диагноз – хронический холецистит или желчекаменная болезнь) и 15 здоровых людей такого же возраста (контрольная группа). Все больные с ГБП получали медикаментозное лечение в соответствии с протоколом лечения. Базовое лечение гингивита осуществляли в соответствии с существующими медицинскими стандартами. В дополнение к базовой схеме лечения гингивита 45 пациентов (основная группа) получали кверцетин (80 мг один раз в день) и препарат инулина из цикория (3 г в день). Препараты принимали перорально за 30 минут до еды в течение 7 дней. Остальные 40 пациентов получали только базовую терапию. У больных с гингивитом в сочетании с ГБП снижается саливация, увеличиваются индексы гигиены и гингивита, растет уровень в слюне биохимических маркеров воспаления (эластаза, МДА), микробной обсемененности (уреаза), снижается активность лизоцима и каталазы, а также антиоксидантно-прооксидантный индекс АПИ. Напротив, ферментативный показатель степени дисбиоза увеличивается почти в 12 раз. Назначение в дополнение к базовому лечению пребиотика инулина и гепатопротектора кверцетина существенно улучшает состояние пародонта пациентов и биохимические показатели слюны.
The state of liver and bile passages influences essentially on the functional activity of most organs and systems, including the character of the course of pathologic processes in oral cavity. The disorders in antimicrobic function of liver may cause the development or aggravate the course of the stomatological disease, in the pathogenesis of which the main role is played by microbe factor. The aim of the investigation is to study the influence on the effectiveness of the treatment of patients with chronic catarrhal gingivitis, developed simultaneously to hepatobiliary pathology (HBP), with hepatoprotector quercethin (bioflavonoid, P-vitamin-active compound with strong antioxidant, anti-inflammatory and adaptogenic effect) and prebiotic inulin, which stimulating the growth of prebiotic microflora, removes the phenomena of dysbiosis, that as a rule develop at pathology of liver. 85 patients at the age of 25-49 years old (diagnosis –chronic cholecystitis and cholelithiasis) and 15 healthy people of the same age (the control group) were under observation. All patients with HBP underwent medical treatment according to the treatment protocol. The basic treatment of gingivitis was held in correspondence of the existing medical standards. In addition to the basic scheme of treatment of gingivitis 45 patients (the main group) got quercethin (80 mg once a day) and the preparation of inulin from chicory (3g/day). The preparations were taken per-oral 30 minutes before meal during 7 days. The other 40 patients got only basic therapy. In patients with gingivitis in combination with HBP the salivation decreases, the indices of hygiene and gingivitis increase, the level of biochemical inflammatory markers (elastase, MDA) and microbe insemination (urease) in saliva grows, the activity of lysozyme and catalase as well as antioxidant-prooxidant index API reduces. On the contrary, the enzymatic index of the degree of dysbiosis grows almost by 12 times. The prescription of prebiotic inulin and hepatoprotector quercethin in addition to the basic treatment improves considerably the state of periodontium of the patients and biochemical indices of saliva.

Opis:
In this work, scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDS) and the time-of-flight secondary ion mass spectrometry (TOF-SIMS) were used to study the particles present on the hair surface of the inhabitants of Wislinka (people environmentally exposed due to the closeness of a dump) in order to obtain the information about the possible influence of dusting from a phosphate waste deposal place. Additionally, the morphology and the composition of fresh phosphogypsum were analyzed. Waste phosphogypsum is formed in the process of a wet phosphoric acid production and there is still a problem with its storage. A thorough understanding of the composition and chemistry of phosphogypsum seems to be necessary to evaluate its environmental impact comprehensively. The results obtained from these two techniques turned out to be complementary and revealed the information expected.

Opis:
Determination of trace elements in combusted materials has always been an interesting field of environmental studies. Particulate matter, in particular, is a serious problem which, can lead to air pollution especially by heavy metals emissions in urban and industrial areas. There is a considerable concern about the elevated level of mercury released during combustion and the proportion of anthropogenic mercury in the environment. Nowadays, small-scale installations have been identified as a significant source-pathway for mercury pollution, particularly those that use coal. A total amount of mercury was determined using Mercury Analyzer. The investigated material consists of bottom ash, fly ash, slag, soot or dust. The obtained results varied according to the type of the material and plant. The developed methodology was checked by carrying out the analysis of certificate material of Soil NCS ZC 73001 and the reference material of Soil-7.

Opis:
The thermohaline characteristics of the Gulf of Aqaba, Red Sea, depict a welldefined seasonal pattern of winter mixing from December to April and summer stratification from May to November. This thermohaline structure is a major controlling factor of the nutrient, chlorophyll a and primary productivity seasonal cycles. The nitrate and chlorophyll a concentration records generated down to 200 m at a vertical resolution of 25 m – weekly during 1994, 1995 and every two weeks from April 1997 through to December 2000 – are employed to assess the nitrogen flux across the summer thermocline of the Gulf of Aqaba. The flux calculations are based on a simple diffusion model that incorporates the physical stress eddy diffusivity factor Kz and a biological stress factor k. Both Kz and k are calculated using the Michaelis-Menten equation and the nitrate concentration gradient. The total nitrate flux of the Gulf of Aqaba during the seven summer months (May–November) is estimated at 0.52 moleN m−2. In relation to established primary productivity values (75.5 gC m−2 (May November)−1) and the generated chlorophyll a records, this yields an f fraction of new to total primary production of 0.50. This relatively high f value is discussed with respect to the geophysical characteristics of the Gulf of Aqaba and similar oceanic basins. The remaining 50% is accounted for by cross-sectional flow from the relatively nutrientrich coral reef coastal habitat and rapid recycling, triggered by high irradiance and water temperature.
