Published: October 2020

Abstract
The most desirable effect of motorization development is providing a drive unit with high performance parameters and reduce the environmental impact. This study presents the results of tests of a self-ignition engine power output and torque. The tested engine was powered with diesel oil and a mixture of fatty acid methyl esters in the proportions of 10%, 30% and 50% with performance additives, for standard settings of the fuel injection system. The tests were carried out on a chassis dynamometer for full load of the engine. The vehicle was placed on the dynamometer rollers and attached to the base by means of belts. The analysis shows that application of the mixture decreases the engine performance parameters to such a degree that the engine is not put at any risk of damage.

Authors: Konieczka Robert , Żak Jakub 
Published: October 2020

Abstract
The introductory part of the article discusses briefly the basic principles and methods of towing large aircrafts. Then, events that occurred while different large passenger planes were towed are analyzed. Based on the analysis, the main causes of plane damages during towing are indicated. The percentage distribution of individual identified risk factors is determined to show that the main cause is the broadly understood human factor, especially errors of service personnel and the crew. Finally, preventive recommendations were made based on the analysis; they can help avoid such events. The analysis stimulates further research in this field and highlights the necessity to continuously analyze the risk, which should minimize the number of towing-related incidents.

Published: October 2020

Abstract
Hydraulic pumps are among the most complex and responsible units from the point of view of aircraft flight safety. One of the most important scientific and technical problems in improving the reliability of hydraulic pumps is to understand the physical nature of the cause of damage in them and on this basis to develop measures and recommendations to ensure their reliability. The article discusses the characteristics of hydraulic piston pairs of hydraulic pumps according to the kinematics of their movement and load conditions. Selected actual damages of axial piston pumps are discussed. The paper presents a simplified 3D solid model of the cylinder-piston assembly and the mechanism for adjusting the inclination of the piston cylinder block, the axial hydraulic pump, and the model of breaking loads for selected elements of this pump. The digital solid model and element load analysis were developed in SolidWorks Simulation.

The Advantages of Using a Bleed of Air from Behind the Compressor and Supplying It Behind the Turbine in an Aircraft Engine
Authors: Kowalski Mirosław , Kotlarz Wojciech 
Published: October 2020

Abstract
The research paper discusses the advantages of using compressor downstream air partial bleed and supplying it downstream of the turbine, which was applied in a prototype of a “bypass” turbojet engine. The impact of such a solution on the value of achieved basic operating parameters of the engine was described, i.e., unit thrust and unit power consumption. The presented attempt to compare these parameters with the parameters achieved for a turbojet, single flow engine is very important; in the first case without air bleed, and in the second, with air bleed to the environment and with the parameters of a turbojet, turbofan engine with a jet mixer.

Authors: Bazela Rafał 
Published: October 2020

Abstract
The research paper reviews selected issues associated with the current state of the armoured (tanks) and infantry fighting vehicle technology, with particular emphasis on the operating effectiveness of elongated sub-calibre projectiles fired from tank guns, which enable full perforation of ca. 500 mm thick armour steel plates. Their efficiency is comparable with the impact of shaped heads with armour steel penetration capabilities, and amounts from 6 to 8 calibres – warhead diameters. Furthermore, the paper discusses a numerical analysis, which shows the velocities of elongated projectiles (of tungsten matrix sinters) required to achieve a determined armour steel penetration depth. In addition, it also presents the performance characteristics of two 100 mm calibre shaped warheads, with copper inserts and apex angles of 51º and 60º.

Authors: Snarska Anna , Palus Katarzyna , Wysocka Dominika , Rytel Liliana 
Published: October 2020

Abstract

Introduction
Due to the widespread occurrence of acrylamide in the environment, its likely carcinogen status, and the suitability of the pig model as a human analogue, the authors decided to evaluate the impact of high and low doses of this compound on the processes of erythropoiesis in swine bone marrow.

Material and Methods
The experiment was carried out on Danish Landrace pigs at the age of eight weeks and body weight about 20 kg. The animals were divided into three equal groups consisting of five pigs in each. Control animals received empty gelatin capsules (placebos). Animals from the first experimental group received a low dose of acrylamide of 0.5 μg/kg b.w./day (> 99% purity; Sigma-Aldrich, Poland), and animals from the second experimental group received a dose 10 times higher. Placebos and acrylamide capsules were administered with feed every morning for 28 days. After anaesthetisation of the animals, bone marrow from the femur was collected into tubes without an anticoagulant on days 0 and 28. After drying and staining, bone marrow smears were subjected to detailed cytological evaluation using a light microscope.

Results
This study showed that high and low doses of acrylamide affected the process of porcine erythropoiesis. The cytotoxic effect of acrylamide on this process was demonstrated in a change of the polychromatic erythroblasts/normochromatic erythroblasts ratio.

Conclusion
Both doses of acrylamide caused a decrease in the number of ortho- and polychromatic erythroblasts.
Die Semantik von ‚Heimat‘ in Zeitschriften/Literatur des späten 19. Jahrhunderts
Authors: Pethes Nicolas 
Published: October 2020

Abstract
Der Beitrag fragt, auf welche Weise das Konzept von ‚Heimat‘ in der zweiten Hälfte des 19. Jahrhunderts im zeitgenössischen Massenmedium der Zeitschrift etabliert und ausgestaltet wird. Im Rahmen des universellen Anspruchs von Rundschau- und Familienblättern kann der lokal fokussierte Heimatdiskurs als zentrierendes Element für die Miszellaneität periodischer Formate identifiziert werden. Er erlaubt es auf diese Weise auch, nach der Funktion der in diesen Zeitschriften veröffentlichten literarischen Texte zu fragen. Ein Vergleich von Adalbert Stifters kanonisierten Nachkommenschaften mit der heute vergessenen Erzählung Der Schütz’ von der Pertisau von Herman Schmid, dem Herausgeber des Heimgarten, zeigt dabei, dass ‚Heimat‘ nicht nur auf geographische und kulturelle, sondern auch auf genealogische Komplexe bezogen wird und der zugehörige Diskurs in Gestalt von Stifters Kontrafaktur des Szenarios bei Schütz auch auf ironische Zuspitzungen hinauslaufen kann – eine Tendenz, die sich allerdings nur erschließt, wenn man Literatur im Kontext ihres Erstpublikationsorts wiederliest.
Wahrnehmungshygiene und Baumpuderrausch. Kleine amazonische Sinneslehre (Lévi-Strauss, Restany, Viveiros de Castro, Kohn, Oloixarac)
Authors: Heyne Elisabeth 
Published: October 2020

Abstract
Der amazonische Regenwald gilt traditionell als Heimat von Sinnestäuschungen. Als das radikal Fremde hält er die selten gewordene Erfahrung bereit, sich als Mensch angesichts einer Fülle von ‚Umwelt‘ in der Unterzahl zu fühlen. Der Beitrag untersucht vor diesem Hintergrund zwei Paradigmen amazonischer Wahrnehmungslehren. Dient er im 20. Jahrhundert als Erfahrungsort für einen letzten Rest „integraler Natürlichkeit“ (Pierre Restany) und bietet eine im Verschwinden begriffene Heimat für den „chronisch heimatlosen“ Europäer (Lévi-Strauss, Frans Krajcberg), scheint er dagegen im 21. Jahrhundert die dringend benötigten Wahrnehmungsmodi für die Verstrickungen zwischen Mensch, Umwelt, Tier, Pflanze und Technik im Anthropozän zu liefern (Eduardo Kohn, Eduardo Viveiros de Castro). Anhand des Romans Constelaciones oscuras (2015; dt. Kryptozän, 2016) der argentinischen Autorin Pola Oloixarac lassen sich die verschiedenen Funktionalisierungen und Imaginationen des Amazonaswaldes als Wahrnehmungsschule nachvollziehen. Zugleich ist der literarische Text mehr als nur fiktionale Verhandlung divergenter Amazonasreferenzen: Er greift indigene Perspektivverschiebungen auf, verkehrt Positiv- in Negativformen und denkt zu Ende, was aktuelle Amazonasethnographien mit Begriffen von Multinaturalismus, Schamanismus und Perspektivismus entwerfen. Da er nicht davor zurückschreckt, die letzte Konsequenz einer „anthropology beyond the human“ zu ziehen, den Menschen als fremdgesteuerten Wirt einer symbiotischen Verbindung zu betrachten, lässt sich an ihm eine Wahrnehmungslehre für die Verstrickungen des Anthropozäns ableiten.

Published: October 2020

Abstract

Background
Finding the appropriate treatment for advanced rectal cancer patients represents a challenge for surgeons. Determining the right diagnosis and the proper treatment requires multidisciplinary collaboration. Our aim is to present a case with advanced stage rectum cancer, who received successful multidisciplinary treatment.

Material and method
A prospective multidisciplinary research is being conducted at our Department from 2018 within which patients with malignant rectal cancer are examined. Patients’ treatment is realized by the same multidisciplinary team. The patient’s preoperative investigations included MRI and a lymph node map designated by radiologists.

Results
In case of a 60-year-old patient the preoperative MRI showed a stenotic formation in the middle level of the rectum that penetrated the seminal vesicle. During surgery, we found a 10x10 cm stenotic, perforated rectal cancer, which penetrated the bladder, seminal vesicle, prostate and sacrum, respectively a metastatic lesion in the livers 8th segment. During surgery R2 recto-sigmoid resection was performed with colostomy. The patient was mobilized on the first postoperative day and bowel movements were regained on the second day. The patient left the hospital on the eighth postoperative day.

Conclusions
Adequate treatment of patients with advanced rectal cancer can be achieved only through multidisciplinary co-operation. Preoperative radiological examinations are mandatory. A map representing the positive colorectal lymph nodes, implemented by the radiologists, can significantly help the surgeons and pathologists.

The morphological response of the heart and spleen following acute myocardial infarction-induced sterile inflammation: a clinicopathological study
Authors: Iuliu Harsa Mihai , Nándor Bányai-Kovács , Emőke Horváth 
Published: October 2020

Abstract

Introduction
as an outcome of sterile inflammation-inducing acute ischemic processes, many splenic cells enter the circulatory system and migrate into the lesion, defending tissues against the spread of ischemia or enhancing necrosis.

Objective
investigating the therapeutic effect of splenic morphological response to sterile inflammation-inducing myocardial infarction.

Material and method
We examined the weight and structure of the heart and spleen of 106 patients deceased due to acute myocardial infarction. These data were correlated with demographic (personal) and epidemiological data, and disease history. After morphological investigation of archived myocardial and splenic tissue samples, the acute ischemia-induced structural alterations of splenic samples were quantified using a digital morphometric method. Results were evaluated in comparison to the myocardial ischemia coefficient. Changes in distribution of ischemia-induced cell types were characterized by defining the immunological phenotypes of macrophages (M1 vs. M2). Spleen samples from patients without history of ischemia were used as controls.

Results
The modification of the spleen weight was associated with an increase in peripheral blood leucocyte levels. Our morphological analysis proved a positive correlation between the ischemia coefficient and the decrease of spleen weight. Structural analysis of splenic tissue revealed the collapse of red pulp sinusoids, a significant size decrease of the white pulp marginal zone (p<0.05), and depleted follicles with irregular margins without any distinct germinative centers. Concurrently, with the proliferation of granulocytes, the increase of M1 macrophages was observed in the myocardium, and a higher M1/M2 ratio was detected in the marginal zone of splenic follicles.

Conclusion
On the background of acute ischemia, time critically determines the dynamic structural changes of the spleen. Along with reducing the marginal zone, immunomodulation targeting its cellular composition will be a putative therapeutic approach in the future.

Published: October 2020

Abstract
In case of chronic diseases patient compliance to long-term treatment is of utmost importance. Patient compliance is generally higher for pharmaceutical forms dispersing in the oral cavity. One classic example for long-term therapy is hypertension. The aim of this study is to obtain nebivolol hydrochloride containing orally disintegrating tablets. As manufacturing technology, direct compression was chosen and rapid disintegration was aimed to be achieved using superdisintegrants. Various formulae have been developed, containing Kollidon and Polyplasdone in different concentrations, and the obtained dry powder mixtures were studied for their rheological properties. Afterwards these mixtures were compressed to obtain tablets. Active ingredient was embedded in the formulations with the shortest disintegration times (15 and 18 seconds) and the obtained tablets were studied for disintegration time, mechanical resistance, drug content and dissolution. Our results show that the pharmaceutical formulations containing Kollidon CL 5% or Polyplasdone XL 3% fulfill the requirements of orally disintegrating tablets, having a disintegration time under 3 minutes, proper mechanical resistance (greater than 80N) and the dissolution of the active ingredient is greater than 80% in 30 minutes.
The influence of genetic variability in IL1B and MIR146A on the risk of pleural plaques and malignant mesothelioma
Authors: Piber Petra , Vavpetic Neza , Goricar Katja , Dolzan Vita , Kovac Viljem , Franko Alenka 
Published: October 2020

Abstract

Background
Asbestos exposure is associated with the development of pleural plaques as well as malignant mesothelioma (MM). Asbestos fibres activate macrophages, leading to the release of inflammatory mediators including interleukin 1 beta (IL-1β). The expression of IL-1β may be influenced by genetic variability of IL1B gene or regulatory microRNAs (miRNAs). This study investigated the effect of polymorphisms in IL1B and MIR146A genes on the risk of developing pleural plaques and MM.

Subjects and methods
In total, 394 patients with pleural plaques, 277 patients with MM, and 175 healthy control subjects were genotyped for IL1B and MIR146A polymorphisms. Logistic regression was used in statistical analysis.

Results
We found no association between MIR146A and IL1B genotypes, and the risk of pleural plaques. MIR146A rs2910164 was significantly associated with a decreased risk of MM (OR = 0.31, 95% CI = 0.13–0.73, p = 0.008). Carriers of two polymorphic alleles had a lower risk of developing MM, even after adjustment for gender and age (OR = 0.34, 95% CI = 0.14–0.85, p = 0.020). Among patients with known asbestos exposure, carriers of at least one polymorphic IL1B rs1143623 allele also had a lower risk of MM in multivariable analysis (OR = 0.50, 95% CI = 0.28–0.92, p = 0.025). The interaction between IL1B rs1143623 and IL1B rs1071676 was significantly associated with an increased risk of MM (p = 0.050).

Conclusions
Our findings suggest that genetic variability of inflammatory mediator IL-1β could contribute to the risk of developing MM, but not pleural plaques.
