Gastric cancer with high risk of intraperitoneal progression: clinical course and current treatments
Authors: Yarema Roman 
Published: May 2018

Abstract
Locally advanced gastric cancer with a high risk of intraperitoneal progression is characterized by poor prognosis. After radical surgery, most patients die during the first two years post-operation as a result of disease progression. The prevailing type of progression and the leading cause of death in patients with gastric cancer is implantation metastasis.
The main risk factors for peritoneal carcinomatosis in such patients include: gastric tumor invasion into serosa, the presence of tumor cells in peritoneal washings, the largeness of the tumor as accompanied by extensive serous lesions, infiltrative type of tumor growth, histological variants of gastric cancer prone to implantation metastasis and metastatic lesions in regional lymph nodes. Systemic chemotherapy does not provide effective eradication of subclinical peritoneal carcinomatosis in patients with locally advanced gastric cancer.
The vast majority of patients who suffer from locally advanced gastric cancer and run a high risk of implantation metastasis are characterized by subclinical peritoneal dissemination at primary diagnosis, which means a rapidly fatal prognosis for such patients. In recent years, however, the paradigm of treatment of locally advanced gastric cancer has changed: a combination of surgery and adjuvant hyperthermic intraperitoneal chemotherapy is used increasingly, and presents an alternative to the previously accepted surgery only approach. It is also likely to increase the survival rate.
Surgical treatment of gastric carcinoma with ovarian metastases
Authors: Olesinski Tomasz 
Published: May 2018

Abstract
Ovarian metastases from extragenital neoplasms are rare. The prevalent sites of the primary tumors were the breast, colorectum and the stomach. The Krukenberg tumor (KT) is defined as a gastrointestinal cancer which metastasized to the ovaries. Metastasis to the ovary may appear at the time of diagnosis of the primary tumor (synchronous) or during observation (metachronous). Common clinical presentations are abdominal distention, pain, palpable mass, bloating, ascites or pain during sexual intercourse. Diagnosis can be made by ultrasound examinations, CT or EMR scans, laparotomy and/or a biopsy of the ovary. The current standard treatment for patients with metastatic gastric cancer is systemic chemotherapy, however, treatment strategy for KTs from gastric cancer has not been clearly established and surgical treatment is considered mainly for metachronous tumors. The prognosis of patients with ovarian metastasis of gastric cancer origin is poorer compared with that of other primary tumors. Although the results of cytoreductive surgery – especially in combination with modern chemotherapy – seems to be promising, the optimal therapeutic strategies for such patients requires further prospective studies.

AbstractIntroduction.So far there are no reports devoted exclusively to the quality of life after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in metastatic gastric cancer. Current literature concerning this issue was, thus, reviewed in order to: 1) search for such data concerning metastatic gastric cancer; 2) assess if the latest reviews evenly pertain to all peritoneal surface malignancies; and 3) conclude if they are a reliable source of data for patients with metastatic gastric cancer.Materials and Methods.The electronic PubMed/MEDLINE and EMBASE databases were retrieved for studies concerning the influence of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy on quality of life in patients with metastatic gastric cancer and regardless of initial diagnosis. The data on the number of patients with particular tumours were analysed and the results were presented in the form of a table.Results.Approximately half of all patients encompassed by the reviews had a form of primary peritoneal surface malignancies. Within peritoneal metastases, the most numerous were colorectal (21-24%) and ovarian cancers (5-15%). Gastric cancers and sarcomas were the smallest defined subgroups (4% each).Conclusions.The promising outcomes in quality of life after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in primary peritoneal surface malignancies might differ from rarely reported ones in metastatic gastric cancer. The problem needs further, gastric cancer-devoted investigations.
Experimental Study On Thermal Wave Type Adsorption Refrigeration System Working On A Pair Of Activated Carbon And Methanol
Authors: Grzebielec Andrzej , Rusowicz Artur , Laskowski Rafał 
Published: May 2018

Abstract
The aim of the study was to examine the efficiency of the thermal wave type adsorption refrigerating equipment working on a pair of activated carbon and methanol. Adsorption units can work in trigeneration systems and in applications driven by waste heat. They can be built also as a part of hybrid sorption-compressor systems, and they are very popular in solar refrigeration systems and energy storage units. The device examined in this study operates in a special mode called thermal wave. This mode allows to achieve higher efficiency rates than the normal mode of operation, as a significant contributor to transport heat from one to the other adsorber. To carry out the experiment a test bench was built, consisting of two cylindrical adsorbers filled with activated carbon, condenser, evaporator, oil heater and two oil coolers. Thermal oil circulation was responsible for providing and receiving heat from adsorbers. In order to perform the correct action a special control algorithm device was developed and implemented to keep the temperature in the evaporator at a preset level. The experimental results show the operating parameters changes in both adsorbers. Obtained COP (coefficient of performance) for the cycle was 0.13.
Optimisation Of Process Parameters In High Energy Mixing As A Method Of Cohesive Powder Flowability Improvement
Authors: Leś Karolina , Kowalski Karol , Opaliński Ireneusz 
Published: May 2018

Abstract
Flowability of fine, highly cohesive calcium carbonate powder was improved using high energy mixing (dry coating) method consisting in coating of CaCO3 particles with a small amount of Aerosil nanoparticles in a planetary ball mill. As measures of flowability the angle of repose and compressibility index were used. As process variables the mixing speed, mixing time, and the amount of Aerosil and amount of isopropanol were chosen. To obtain optimal values of the process variables, a Response Surface Methodology (RSM) based on Central Composite Rotatable Design (CCRD) was applied. To match the RSM requirements it was necessary to perform a total of 31 experimental tests needed to complete mathematical model equations. The equations that are second-order response functions representing the angle of repose and compressibility index were expressed as functions of all the process variables. Predicted values of the responses were found to be in a good agreement with experimental values. The models were presented as 3-D response surface plots from which the optimal values of the process variables could be correctly assigned. The proposed, mechanochemical method of powder treatment coupled with response surface methodology is a new, effective approach to flowability of cohesive powder improvement and powder processing optimisation.
Extinction of Lasiommata petropolitana (Fabricius, 1787) (Lepidoptera: Nymphalidae) in the Czech Republic: a case of habitat loss at a range margin
Authors: Spitzer Lukáš , Beneš Jiří , Konvička Martin 
Published: May 2018

Abstract
Lasiommata petropolitana is a boreomontane butterfly, declining in Central Europe and not recorded in the Czech Republic since 1975. Based on revision of all existing archival records and results of recent targeted surveys in mountainous regions of East Moravia, area of its past occurrence, we document its gradual retreat and ultimate regional extinction. The historical range, marginal with respect to contiguous distribution along the Carpathian mountain chain, included both foothills and higher elevations of Bílé Karpaty, Hostýnské Vrchy, Javorníky, Moravskoslezské Beskydy and Vsetínské Vrchy Mts; pre-1950 records document also a past occurrence at calcareous bedrock localities in Brno environs. Other past lowland records (Oslava valley, Olomouc, Znojmo) were due to misidentifications. Within the historical Czech range, the butterfly inhabited pastures with exposed calcareous, flysh or sandstone bedrock, maintained by traditional grazing. The decline of the species proceeded from lower elevations and foothills towards mountain ridges. The higher elevation sites were encroached by successional changes, or intentionally afforested, with post-war decline of mountain grazing. This development went largely unnoticed by conservation authorities, and represents a loss of mountain butterfly from marginal parts of its range.
Alternative Possibilities, Volitional Necessities, and Character Setting
Authors: Matheson Benjamin 
Published: May 2018

Abstract
Conventional wisdom suggests that the power to do otherwise is necessary for being morally responsible. While much of the literature on alternative possibilities has focused on Frankfurt’s argument against this claim, I instead focus on one of Dennett’s (1984) arguments against it. This argument appeals to cases of volitional necessity rather than cases featuring counterfactual interveners. van Inwagen (1989) and Kane (1996) appeal to the notion of ‘character setting’ to argue that these cases do not show that the power to do otherwise is unnecessary for moral responsibility. In this paper, I argue that their character setting response is unsuccessful.
Use of Algae in Active Biomonitoring of Surface Waters
Authors: Rajfur Małgorzata , Kłos Andrzej 
Published: May 2018

Abstract
Biomonitoring studies have been carried out in three retention reservoirs located in the Opole Province (southern Poland): Turawa reservoir, Nysa reservoir and Otmuchow reservoir. The increases of concentrations of Mn, Fe, Cu, Zn, Cd and Pb in fresh water algae Spirogyra sp. and sea water Palmaria palmata (Linnaeus) Weber & Mohr, exposed in the analysed waters, were determined by the atomic absorption spectrometry method (AAS). Also the waters pH, conductivity and Mn and Fe concentrations were determined. The concentrations of Cu, Zn, Cd and Pb in the analysed waters were lower than the method limit of determination. The analyses were carried out during the period from June to July 2014. The differences between the increases of heavy metal concentrations in the samples of algae found along the coastline were indicated; they result from different distances from the pollution sources, such as sediments or drainage from the areas adjacent to the reservoirs. Better sorption characteristics of Palmaria palmata in comparison to Spirogyra sp. were indicated. An empirical interrelation was also tested, the application of which after modification may enable the quantitative assessment of waters pollution with heavy metals, based on the analysis of the concentration of the element in the algae thallus.

Authors: Słyś Daniel , Stec Agnieszka 
Published: May 2018

Abstract
Climate change, improper use of water resources, surface waters pollution as well as increase of water requirements are the results of growing population of people in the world. It causes water deficiency in majority of countries in the world, including Poland. Due to the water pollution advanced technologies for its treatment are in demand, what leads to increase of water price. In this connection, there are more often taken actions to reduce water consumption by using rainwater to flush toilets, wash cars, do laundry or water green areas. This publication presents results of Life Cycle Cost analysis of two variants of water supply systems designed for multi-family residential building situated in Rzeszow. In line with LCC methodology the calculations were made throughout the whole life-cycle of the building considering initial investment outlays intended for construction of water supply system as well as operation and maintenance costs. In the first of analyzed variants it was assumed that the system would be fed by municipal water supply network. In the second variant rainwater harvesting system for domestic use was additionally applied. Rainwater stored in the tank would be used in sanitary installation to flush toilets, what leads to lowering the costs of municipal water purchase, reducing fees for rainwater discharge to sewage system and consequently is beneficial for financial standing of the examined building.

Abstract
This work presents the analysis of the influence of compost and reclamation substrate addition and mineral fertilizers application on leaching of mineral nitrogen, microbial activities, soil hydrophobicity and plant biomass production. To demonstrate the effect of compost, reclamation substrate and mineral nitrogen (Nmin) addition on above parameters, the pot experiment was performed. As a model crop, Deschampsia caespitosa L. was used and cultivated for 63 days in climate chamber. The leaching of Nmjn was measured by application of ion exchange discs, soil hydrophobicity was determined based on the values of saturated hydraulic conductivity (Ksat) and microbial activity was expressed as basal (BR) and substrate induced respiration (SIR). Four variants (V1-V4) with different doses of fertilizers were prepared: V1 - control without addition of fertilizers; V2 - this variant of experiment was prepared as mixture of compost and arable land in ratio 7:3; V3 - 90 g/m2 of mineral fertilizers NPK (in the ratio 1:1:1) were applied there and into V4, dose 30 g of compost were applied. The significant differences (P < 0.05) in the detection of Nmin, values of Ksat
and SIR were found. The highest decrease of mineral nitrogen leaching was observed by the simultaneous applications of compost (V4) to arable soil, about 50% in comparison with the variant V4 (application of mineral fertilization) and about 10% in comparison with the control. Variants with addition of compost (V2 and V4) showed higher values than variants without, which were measured at three stages (before application of Nmin - 12 days after establishment of the experiment; after application of Nmin - 34 days; at end of the experiment - 63 days). During the experiment, two types of respiration were measured: BR and SIR. The significant differences in SIR were found between variants with addition of compost and variants without. The SIR (cumulative production of CO2) was higher about 25% in variants V2 and V4 compared to variants V1 and V3. The highest values of Ksat
were found in variants with addition of compost. Conversely, the lowest value of Ksat
was detected in variant with addition of Nmin. Low values of Ksat
indicate an increased level of hydrophobicity.
Environmental values in the petrochemical industry: A Q-method study in South West Iran
Authors: Ghoochani Omid M. , Bakhshi Azadeh , Cotton Matthew , Nejad Azar Hashemi , Ghanian Mansour 
Published: May 2018

Abstract
Achieving sustainable development in different regional and cultural contexts is dependent, in part, upon an understanding of key actors’ underlying environmental, social and economic values. The social research technique called Q-methodology presents an effective means to explore such values as a matter of discourse: revealing the typologies of stakeholder perspectives within a given debate. Q-method involves factor analysis of participant rank-ordered preselected statements on a topic. The resultant factors are then reinterpreted as social discourses. In this study we use Q-methodology to explore the environmental values of Health Safety and Environmental (HSE) managers in petrochemical companies in Khuzestan province in southwest Iran. Khuzestan is a key region of petrochemical product development, with significant associated environmental pollution effects. Understanding HSE managers’ attitudes to environmental protection is of value in predicting broader environmental impacts to the region, given the relative importance of their role in regulating the environmental performance of this industry. Our results reveal four distinct and varied perspectives on environmental protection labelled: ‘Environmental stewardship’, ‘Environmental presentism’, ‘Technological optimism’ and ‘Enlightened anthropocentrism’. We then discuss how these four emergent perspectives correspond to broader environmental discourses as categorized by John Dryzek: i.e. green rationalism, economic rationalism, prometheanism and ecological modernization respectively.

Authors: Smołka-Danielowska Danuta 
Published: May 2018

Abstract
This study presents preliminary research results, with regard to the concentration of chosen trace elements (Mn, Cr, Tl, Ni, Cu, Zn, As, Cd, Ba, Pb) in waste, which was produced in the process of combustion of solid fuels (hard coal and flotation concentrate of bituminous coal) in individual household furnaces in Poland (in the Upper Silesian Industrial Region). 27 samples of ash, 4 samples of hard coal and 2 samples of flotation concentrate of bituminous coal were prepared for the research. Methods such as: ICP-MS, X-ray diffraction by means of the powder method and scanning electron microscopy were used during the research. In the ash samples obtained from the combustion of hard coal, the highest average concentrations were: Mn (1477.7 ppm), Ba (1336.4 ppm) and Zn (599.7 ppm). In the samples obtained from the combustion of flotation concentrate of bituminous coal, the highest average concentrations was stated for: Zn (762.4 ppm), Mn (668.5 ppm), Pb (552.1 ppm) and Ba (211.7 ppm). Crystalline components were determined by used the X-ray diffraction method and the samples of ash obtained from the combustion of hard coal contained: anhydrite, gypsum, hematite, magnetite, quartz, calcite, mullite, periclase, kaolinite, dolomite, pyrite, sphalerite, galena and feldspars (albite-anorthite). The samples of ash obtained from the combustion of flotation concentrate of bituminous coal contain: pyrite, quartz, potassium feldspar, muscovite and kaolinite. The scanning electron microscope analysis enabled the identification of the chemical composition of single ash grains and determined their morphology (aluminosilicate forms, substance PbS and ZnS, oxides of Ni, Cu and Mn, monazite, xenotime).
Contemporary foundations of the theory of urban development – case study smart, slow and compact city theory
Authors: Rysz Kamil , Mazurek Kinga 
Published: May 2018

Abstract
The issue of the concept of development and urban planning in an optimal manner is as old as cities. It has not yet been established which human activities are to be considered as conscious and planned space development. It is assumed that the beginnings of rational, thoughtful urban planning should be sought at a time when cities began to be treated as a single organism, which should function smoothly, guarantee the safety of its inhabitants through defence functions and provide a higher standard of living. The effect of these assumptions was the logical placement of buildings, transportation systems and infrastructure, as well as recreational areas so that life in the city was something more than just miserable existence. This article overlooks former planning theories such as the theories of location by J.H. von Thunen or A. Weber, as well as the projects of a garden city by E. Howard and Functional Warsaw by J. Chmielewski and S. Syrkus. Instead, it focuses on what is currently, at the beginning of the 21st century, up to date and combines contemporary concepts of sustainability and new technologies, and treats the city as a resource of limited space, buildings, infrastructure and people representing both purchasing power and the labour force. The article, apart from theoretical considerations, focused on realizations of ideas in practice, quoting both sectoral solutions related to the organization of transportation in the city, as well as to projects of entire cities.
Human – river relations at various stages of development of water front factory settlements in Łódź
Authors: Szkurłat Elżbieta 
Published: May 2018

Abstract
The purpose of this article is to analyze and clarify the circumstances which led to the current condition and degradation of the watercourses and rivers of Łódź. These rivers were the decisive factor in initiating and stimulating the industrial development of the city. A detailed analysis examined changes in the management of river waters in the vicinity of the socalled water-front factory settlements (referred to locally as “posiadła”) in the River Jasień valley. This was the location of one of the first industrial settlements within the city of Łódź and took place shortly after the city was included by the Polish Kingdom authorities (in 1821) in the group of so-called factory cities intended for the development of the textile industry - initially with emphasis on the cloth and linen making industry, with further transformation into the cotton industry. The article presents the forms and methods of use of the River Jasień in the period from the beginning of the 19th century up to the present. The specification assumed therefore the period of agricultural usage in the form of water mills, through textile manufacture, industrial production and the period after the fall of the textile industry. The River Jasień is an outstanding example of the way, in which people have “treated” the river during the successive stages of technological development of textile production. How close to the river they settled at the early stages of industrial development, slowly “moving away” from the river, leading to its gradual degradation, and abandoning it, restraining it to a covered channel, to ultimately forgetting it ever existed. The changes in these man - river relationships, as described in this document, can lead to conclusions for the future direction for the current spatial policy of the city. Also about these riverside post-industrial areas, with regard to the need to restore their original values and the need to protect and conserve their unique natural character and cultural heritage.
