    Opis:
    In this work, there were shown the research results concerning anaerobic digestion in the mesophilic condition. There was done the assessment of content of chosen heavy metals and their fractions in dairy sewage sludge before and after digestion process. The research was conducted with the use of laboratory installation on the base of mixture of excessive and floatation sludge. The process parameters were adopted from the modernization project of dairy sewage treatment plant of Mlekovita cooperative in Wysokie Mazowieckie. The results showed that in case of agricultural use of sludge, the total amount of heavy metals in sludge after anaerobic digestion was sharply lower that the values demanded in regulation concerning municipal sewage sludge. The process of sludge digestion caused the increase of metals content in dry matter of sludge. Metals speciation was determined with the use of scheme in accordance with methodology worked by BRC, which meant indicating four fractions. In case of lead, copper and zinc, the researches of anaerobic digestion process of dairy sludge showed the little increase of immobile fraction. The decrease of metals fraction was observed in case of cadmium, nickel and the clearest – chromium.
    W pracy zaprezentowano wyniki badań dotyczących procesu stabilizacji beztlenowej w warunkach mezofilowych. Dokonano oceny zawartości wybranych metali ciężkich i ich frakcji w osadzie mleczarskim przed i po procesie stabilizacji. Badania prowadzono z zastosowaniem układu laboratoryjnego w oparciu o mieszaninę osadu nadmiernego i flotacyjnego. Parametry procesu zostały adoptowane z projektu modernizacji oczyszczalni ścieków mleczarskich firmy Mlekovita w Wysokiem Mazowieckiem. Stwierdzono, iż ogólna ilość metali ciężkich w osadzie po procesie stabilizacji beztlenowej jest znacznie niższa niż wartości wymagane w rozporządzeniu w sprawie komunalnych osadów ściekowych w przypadku rolniczego wykorzystania osadu. Proces stabilizacji osadu spowodował wzrost zawartości metali w suchej masie osadu. Specjację metali określono za pomocą schematu zaproponowanego przez zgodnie z metodyką opracowaną przez BCR wyodrębniając cztery frakcje. Przeprowadzone badania procesu stabilizacji beztlenowej osadów mleczarskich wykazały niewielki wzrost frakcji niemobilnej w przypadku ołowiu, miedzi i cynku. Zmniejszenie tej frakcji metali zaobserwowano w przypadku kadmu i niklu, i najwyraźniej w przypadku chromu.

    Opis:
    In Poland, as well as worldwide, an increase in craft beer production can be observed. In the last several years, more than 150 of such breweries have appeared and according to Polish Brewery Association, their number might ultimately reach 500. Many of them emerge in the areas with no access to a central sewerage system so they have to solve the problem of waste management on their own. The article presents the results of research on the possibility of using a hybrid system for biological treatment of sewage from craft breweries. The sewage came from a craft brewery Waszczukowe located in the Podlaskie province. A laboratory scale model consisted of a trickling filter (TF) (research model Gunt CE701e) and vertical flow constructed wetland (SS-VF). Innovative filling (Certyd produced by LSA company) of TF and SS VF was applied. The conducted study included determining the changes in the sewage parameters during hybrid treatment, as well as TF and SS VF efficiency separately. The aim of the research was to show the possibility of treating sewage to a point when it was possible to discharge it to a receiver, in compliance with the Polish legal regulations. The research results might be used in designing a treatment system or sewage pretreatment in craft breweries. The average efficiency of TF operating with 100% recirculation was 76% for BOD5, 80% for COD, 26% for TN and 34% for TP, while the total treatment efficiency of a hybrid system (TF and SS-VF) was 98%, 98%, 72% and 77%, respectively. The load of TF during operation with recirculation was on average 0.38 kg BOD5 m-2d-1, 0.57 kg COD m-2 d-1. The load of SS-VF was on average 0.09 kg BOD5 m-2 d-1 and 0.12 kg COD m-2d-1. The obtained results of hybrid treatment permitted to discharge the sewage to the receiver.

    Opis:
    The problem of wastewater treatment from craft breweries emerged in Poland about 10 years ago when an increase in the number of small breweries was observed. Plants located in small towns are forced to solve the problem on their own. One of the possibilities is to use low-cost technology of constructed wetlands with subsurface and surface flow. The purpose of the research was to test the possibility of effective treatment of sewage from a craft brewery in a lab-scale research installation and to determine the parameters for designing a real scale plant. Wastewater from the Waszczukowe brewery was used in the study. The research system consisted of a retention and aeration tank, SS-VF subsurface flow and FWS surface flow beds. An innovative Certyd filling produced by LSA company was used. The high efficiency of SS-VF bed and the entire research system was found. The removal efficiency in SS VF was on average 89.7% for BOD5, 90.5% for COD, 54.6% for TN and 52.1% for TP. For whole treatment it was respectively 97.1%, 96.7%, 72.6% and 61.3%. A high organic matter removal effect was found for the SS-VF bed (87.1 g BOD5g m-2 d-1) and a relatively low for the FWS (3.0 BOD5g m-2 d-1). The study confirmed the need for plant design based on hydraulic load and required load removed per unit area.

    Opis:
    Introduction: Congenital factor VIII deficiency is a rare hemorrhagic disorder inherited in an autosomal recessive pattern. Surgical treatment with insufficient diathesis correction is burdened with a high risk of bleeding complications. The aim of the study was to evaluate the surgical outcome in patients with congenital factor VII deficiency and assessment of the efficacy and safety of recombinant activated factor VII (rFVIIa) used for perioperative hemostatic coverage in our two schemas of substitutive therapy. Material and methods: In the years 2002-2017 a total of 22 patients with congenital factor VII deficiency were subjected to surgery. Substitution therapy relied on rFVIIa used in two schemas. One involved 15 patients with factor VII activity of <10% of normal value who were injected rFVIIa at a dose of 30 μg/kg b.w. every 12 hours on surgery day, 15 μg/kg b.w. every 12 hours on the first postoperative day and 15 μg/kg b.w. every 24 hours on the following days. The second schema involved 7 patients with factor VII activity of 10-25% of normal value who were given rFVIIa at a dose of 15 μg/kg b.w. every 12 hours on surgery day and the first postoperative day; then the same dose was administered every 24 hours on consecutive days. The treatment continued for 4-10 days. Results: In 22 patients a total of 26 surgeries were performed; 17 surgeries in 15 patients with factor VII <10% of normal and 9 in 7 patients with factor VII deficiency of 10-25% of normal. The surgeries included: 9 cholecystectomies (8 laparoscopic, 1 open), 7 thyroidectomy procedures, 2 exploratory laparotomies, 1 left hemicolectomy, 1 total proctocolectomy, 3 inguinal hernia repairs and 3 excisions of varicose veins. One patient with factor VII activity of 9% required an additional dose of rFVIIa in the intraoperative period due to diathesis bleeding. Intraoperative hemostasis was normal for all other patients; no postoperative hemorrhagic complications were reported. In patients with FVII activity <10% average daily dose of rFVIIa was 31.3 (range 20-56) μg/kg b.w., total daily dose 186 (136-303) µg/kg b.w., total dose of rFVIIa - 15.2 (12-112) mg. In patients with FVII activity 10-25% the doses were 21.2 (15-31), 117 (46-271) µg/kg b.w. and 9.1 (6-17) mg respectively.

    Opis:
    Introduction: Bleeding from esophageal varices is a serious clinical condition in hemophilia patients due to congenital deficiency or lack of clotting factors VIII (in hemophilia A) and IX (in hemophilia B), decreased clotting factor II, VII, IX, X synthesis in the course of chronic liver disease and hipersplenic thrombocytopenia. The aim of this study was to assess the efficacy and safety of endoscopic sclerotherapy in acute esophageal variceal bleeding and in secondary prophylaxis of hemorrhage. The aim was also to investigate the optimal activity of deficiency factors VIII or IX and duration of replacement therapy required to ensure proper hemostasis after sclerotherapy procedures. Material and methods: 22 hemophilia patients (A-19, B-4) with coexistent liver cirrhosis and active esophageal variceal bleeding treated with endoscopic sclerotherapy were subjected to prospective analysis. The patients who survived were qualified to repeated sclerotherapy procedures every 3 weeks within secondary prophylaxis of bleeding (investigated group). A 3-day substitution therapy enhanced the infusion of the deficient or lacking factor in doses allowing to reach 80-100% of normal value activity of factor VIII on the 1st day and 60-80% in the next two days. The desired activity of factor IX was 60-80% and 40-60% respectively. The control group consisted of 20 non-hemophiliac patients with liver cirrhosis comparable in terms of age, sex, stage of advancement of liver cirrhosis, who underwent the same medical proceedings as the investigated group. Results: Active esophageal bleeding was stopped in 21 of 22 (95%) hemophilia patients. Complications were observed in 3 patients; 2 patients died. The rate of hemostasis, complications and deaths in the control group were comparable and no statistical differences were found. In hemophilia patients subjected to secondary prophylaxis of hemorrhage, in 18 of 20 (80%), complete eradication of esophageal varices was achieved after 4 to 7 sclerotherapy procedures in 1 patient (average 5.4). Recurrent bleeding was observed in 15% of patients, complication in 20%; 1 patient died. Time lapse from bleeding to eradication was 12-21 weeks (average 15.2). In the control group the rate of variceal eradication, complication and deaths was comparable and no statistical differences were found. The usage of factor VIII concentrates was as follows: in hemophilia A, in a severe form - 80.9 U/kg b.w./day, in hemophilia A in a severe form with an inhibitor <5 BU – 95.2 U/kg b.w./day, in mild form – 64.2 U/kg b.w./day and in severe hemophilia B – 91.6 U/kg b.w./day. Conclusions: Sclerotherapy is an effective method in the management of esophageal variceal bleeding in hemophilia patients. It is also effective for total eradication of varices when applied as a secondary prophylaxis of hemorrhage. In our opinion, a 3-day replacement therapy at the applied doses is sufficient to ensure hemostasis and avoid bleeding complications.

    Introduction. Magnesium (Mg) plays a crucial role in cell physiology and its deficiency may cause many disorders which often require intensive treatment. The aim of this study was to analyse some factors affecting preoperative plasma Mg concentration in patients undergoing coronary artery bypass grafting (CABG). Materials and method. Adult patients scheduled for elective CABG with cardio-pulmonary bypass (CPB) under general anaesthesia were studied. Plasma Mg concentration was analysed before surgery in accordance with age, domicile, profession, tobacco smoking and preoperative Mg supplementation. Blood samples were obtained from the radial artery just before the administration of anaesthesia. Results. 150 patients were studied. Mean preoperative plasma Mg concentration was 0.93 ± 0.17 mmol/L; mean concentration in patients – 1.02 ± 0.16; preoperative Mg supplementation was significantly higher than in patients without such supplementation. Moreover, intellectual workers supplemented Mg more frequently and had higher plasma Mg concentration than physical workers. Plasma Mg concentration decreases in elderly patients. Patients living in cities, on average, had the highest plasma Mg concentration. Smokers had significantly lower plasma Mg concentration than non smokers. Conclusions. 1. Preoperative magnesium supplementation increases its plasma concentration. 2. Intellectual workers frequently supplement magnesium. 3. Smoking cigarettes decreases plasma magnesium concentration.

    Wstęp: Nowotwory mające swoją etiologię w gruczołach ślinowych występują rzadko i stanowią ok. 3–10% wszystkich guzów w obrębie głowy i szyi. Materiał i metody: W latach 2006–2016 w Klinicznym Oddziale Chirurgii Czaszkowo-Szczękowo-Twarzowej Wojskowego Instytutu Medycznego w Warszawie z powodu nowotworów ślinianek przyusznych hospitalizowano i leczono 149 pacjentów. Podstawą do analizy były historie chorób pacjentów, wyniki badań histopatologicznych oraz protokoły zabiegów operacyjnych. Wyniki: W 126 przypadkach guzy były łagodne, natomiast w 26 guzy złośliwe. Analizując wyniki można stwierdzić, że nowotwory - zarówno łagodne, jak i złośliwe – częściej występowały u mężczyzn. Średni wiek całej grupy badanych wynosił 58,3 lat, dla zmian złośliwych – 65,5 lat, a dla zmian łagodnych był nieznacznie niższy i wynosił 56,9 lat. Wśród pacjentów objętych analizą szczyt zachorowalności przypadał na przedział wiekowy 60–69 lat. Ponadto zwraca uwagę, iż przedział ten był taki sam dla ogólnej liczby guzów, jak i nowotworów łagodnych, natomiast dla nowotworów złośliwych był nieznacznie wyższy i wynosił 70–79 lat. Z analizy zebranego materiału wynika, że guzy łagodne występowały znamiennie częściej, stanowiąc 84,56% wszystkich guzów. Najczęstszymi rozpoznaniami wśród nowotworów łagodnych były gruczolak wielopostaciowy (adenoma pleomorphicum) oraz gruczolak limfatyczny (adenolymphoma), które stanowiły łącznie 93,66%. Rezultaty badań wskazują, że wśród nowotworów złośliwych dominowały: gruczolakorak polimorficzny o niskiej złośliwości (polymorphous low-grade adenocarcinoma) występujący w 26,07% przypadków, gruczolakorak inaczej nieokreślony (adenocarcinoma NOS) oraz rak zrazikowokomórkowy (acinic cell carcinoma). Każdy z nich stanowił po 13,04% rozpoznań. Jak wynika z przeprowadzonej analizy najczęstszą metodą leczenia było leczenie chirurgiczne jako metoda stosowana samodzielnie. Wnioski: Uzyskane z retrospektywnej analizy dane korelują z piśmiennictwem krajowym i światowym.

    Pleomorphic adenoma, also known as tumor mixtus, is one of the most common types of benign neoplasm of the salivary gland, which presents as a slow growing, painless tumor. Major salivary glands are the typical localization of this neoplasm. It rarely undergoes malignant transformation, however may recur locally post resection. In this study, we present the results of a retrospective analysis of 104 patients treated at the Clinical Department of Cranio-Maxillofacial Surgery, Clinic of Otolaryngology and Laryngologic Oncology of the Military Institute of Medicine between 2004 and 2015 due to pleomorphic adenoma. The study confirmed the parotid gland as the most common location of tumor mixtus. In some cases, the large size of the tumor and its location were the cause of life-threatening complications.

    Opis:
    The paper presents a design and performance analysis of a photosensor device enabling the measurement of the visible light illuminance. The sensor is designed for use in the light metering matrix of a mobile measurement platform allowing the correct operation of inpavement airport lamps. This kind of control can be required by regulations and must meet the standards defined by the European Union Aviation Safety Agency (EASA). An important assumption of the solution was to obtain the highest possible speed of a measurement acquisition so that the control process would take place in a relatively short time. The proposed module concept is dedicated to the task of testing the quality of airport lamps, due to the characteristics of the photosensitive elements matching the light beams emitted by luminaries. The device is based on a VTP1220FBH photodiode and an ATmega328P microcontroller, which, in addition to the analogue-to-digital conversion and correction, sends the results back to the master unit via the I²C bus.

    Opis:
    Abiotic stressors contribute to growth restriction and developmental disorders in plants. Early detection of the first signs of changes in plant functioning is very important. The objective of this study was to identify chlorophyll fluorescence parameters that change under phosphorus deficiency stress in cucumber. In this work, a trail to study the early changes caused by phosphorus deficiency in cucumber plants by analysing their photosynthetic performance is presented. Chlorophyll-a fluorescence (ChF) parameters were measured every 7 days for a period of 28 days. Measurements were made separately on young and old leaves and on cucumber fruit. Parameters that decreased during the stress were: p2G, PI abs, PI total, REo/CSo, and TRo/CSo. P deficiency decreased total electron carriers per RC (ECo/RC), yields (TRo/ABS (Fv/Fm), ETo/TRo, REo/ETo, ETo/ABS and REo/ABS), fluxes (REo/RC and REo/CSo) and fractional reduction of PSI end electron acceptors, and damaged all photochemical and non-photochemical redox reactions. Principal component analysis revealed a group of ChF parameters that may indicate early phosphorus deficiency in cucumber plants. Our results are used in the discovery of sensitive bioindicators of phosphorus deficiency in cucumber plants. Most JIP test parameters are linked to mathematical equations, so we recommend using of advanced statistical tools, such as principal component analysis, which should be considered very useful for stress identification. It has also been shown to be more effective in multivariate methods compared to univariate statistical methods was demonstrated.

    Opis:
    The presented research shows that commercially available graphene on quartz modified with rhenium oxide meets the requirements for its use as a conductive and transparent anode in optoelectronic devices. The cluster growth of rhenium oxide enables an increase in the work function of graphene by 1.3 eV up to 5.2 eV, which guarantees an appropriate adjustment to the energy levels of organic semiconductors used in organic light-emitting diode devices.
