Opis:
This review presents the usage of adhesives and binders for agglomeration of particle materials, including waste, in order to obtain strong bodies. The binding materials were classified into three categories: inorganic binders, organic binders, and compound binders. Many examples of the agglomeration effect of binders in view of their adhesive and thickening reveal that they have a significant impact on the qualities and use of waste lumps. Binders for fine waste granulation, briquetting, and pelletizing were demonstrated in-depth. In all cases, the mechanical strength of the agglomerates produced was increased. It was observed that the majority of the additives may be easily obtained from waste resources, posing a minimal environmental risk.

Opis:
From the beginning of the deterministic chaos research, the unpredictability has been its central theme. Interesting questions arise here: What are the consequences of chaos for the fine tuned processes? Are there fine tuning systems in reality? We investigate the possibility of defining a fine tuning parameter in terms of the Lyapunov principal exponent. We will critically evaluate the existing formulation of Hetesi and Vegh. We argue that such a quantification of a fine tuning parameter may be useful in the context of the debate between indifference and fine tuning principles for the Universe. We also propose how to define fine tuning evolutional paths of the Universe by using concepts of dynamical systems, namely the method of separatrices in the phase space.

fine-needle aspiration biopsy
Opis:
Aim: The aim of the study was to review two techniques that can be used to verify focal lesions in the breasts: fine-needle aspiration biopsy and core-needle biopsy. Material and methods: Fifty-five articles (original papers and reviews), half of them published within the past 5 years, were included in the analysis. The authors also took their own experience into account. Results: Pre-operative assessment of focal lesions in the breasts is crucial in the planning of further therapeutic management. The role of fine-needle aspiration biopsy has been reduced lately due to its low sensitivity and specificity as well as a high rate of non-diagnostic, suspicious and false negative results. This method does not enable one to differentiate between in situ and invasive disease. Currently, fine-needle biopsy is recommended for cystic lesions, suspected of being recurrences in the chest wall, and lymph node metastases. Core-needle biopsy is the basic diagnostic method of breast lesions. According to the recommendations of the Polish Ultrasound Society and American College of Radiology, BIRADS 4 and 5 lesions should be evaluated histopathologically. Core-needle biopsy makes it possible to establish a final diagnosis more frequently than fine-needle biopsy, both in the case of benign and malignant lesions. It delivers more information about the nature of a tumor (mutation of HER-2, estrogen and progesterone receptors and Ki-67 index). Its limitations include: underestimation of invasion and failure to recognize the components of ductal carcinoma in situ in papillary and atypical lesions. Single fine-needle aspiration biopsy is inexpensive, but when considering the cost of further diagnosis due to non-diagnostic, suspicious and atypical results, this method generates high additional costs. Conclusions: Microscopic verification of focal breast lesions is crucial for further therapeutic decisions. It has been proven that histopathological verification is more accurate and has more advantages than cytological assessment.
Cel pracy: Celem pracy było przedstawienie dwóch technik weryfikacji zmian ogniskowych w piersiach: biopsji aspiracyjnej celowanej cienkoigłowej i biopsji gruboigłowej. Materiał i metody: Analizie poddano 55 artykułów (prac oryginalnych i przeglądowych), z których prawie połowa została opublikowana w ciągu ostatnich 5 lat. Autorzy uwzględnili również własne doświadczenia. Wyniki: Przedoperacyjna ocena zmian ogniskowych w piersiach jest niezbędna w planowaniu postępowania terapeutycznego. W ostatnim czasie rola biopsji aspiracyjnej cienkoigłowej celowanej uległa zmniejszeniu ze względu na niską czułość i swoistość, jak również wysoki odsetek wyników niediagnostycznych, podejrzanych i fałszywie ujemnych. Metoda ta nie pozwala na różnicowanie pomiędzy nowotworem in situ a inwazyjnym. Obecnie biopsja cienkoigłowa jest rekomendowana w przypadku zmian płynowych, podejrzanych o wznowę w ścianie klatki piersiowej oraz przerzutów do węzłów chłonnych. Biopsja gruboigłowa jest podstawową metodą diagnostyczną zmian w piersiach. Zgodnie z zaleceniami Polskiego Towarzystwa Ultrasonograficznego i American College of Radiology zmiany kategorii 4 i 5 według klasyfikacji BIRADS powinny zostać poddane weryfikacji histopatologicznej. Biopsja gruboigłowa pozwala na postawienie ostatecznej diagnozy częściej niż biopsja cienkoigłowa zarówno w przypadku zmian łagodnych, jak i złośliwych; dostarcza więcej informacji o charakterze guza (obecność mutacji HER-2, receptorów progesteronowych i estrogenowych oraz wskaźnika Ki-67). Do jej ograniczeń zalicza się niedoszacowanie inwazji oraz nierozpoznawanie komponentów raka przewodowego in situ w zmianach brodawkowatych i atypowych. Cena pojedynczej biopsji aspiracyjnej celowanej cienkoigłowej jest niewielka, jednak po uwzględnieniu kosztów dalszej diagnostyki wyników niediagnostycznych, podejrzanych i atypowych metoda ta generuje wysokie koszty dodatkowe. Wnioski: Weryfikacja mikroskopowa zmian ogniskowych w piersiach jest kluczowa w podejmowaniu dalszych decyzji terapeutycznych. Udowodniono, że weryfikacja histopatologiczna jest dokładniejsza i ma więcej zalet niż ocena cytologiczna.

Opis:
Wyraźnie zauważalne jest, że ustawodawca dla podniesienia efektywności tworzonych przez siebie regulacji prawnych z zakresu prawa administracyjnego sięga po sankcje, mające postać administracyjnych kar pieniężnych. Nakładane są one w razie niewykonania lub nienależytego wykonania obowiązków wynikających z konkretnego przepisu prawnego przez ich adresata. Mając jednak na uwadze to, że w procedurze ich nakładania nie są stosowane środki ochrony, w przeciwieństwie do kar wymierzanych w prawie karnym, do możliwości nakładania kar pieniężnych powinno się podchodzić się z większą ostrożnością. Zwłaszcza że szczególnie wykorzystywany jest ich represyjne oddziaływanie.
It is clearly noticeable that the legislator, in order to increase the effectiveness of legal regulations in the field of administrative law created thereby, reaches for sanctions in the form of administrative fines. They shall be imposed in the event of non-performance or improper performance by the addressee of obligations under a specific legal provision. However, bearing in mind that there are no protective measures in the procedure for their imposition, unlike penalties under criminal law, the possibility of imposing fines should be treated with greater caution. Their repressive impact is particularly exploited.

Raw diatomite (RD) and diatomite concentrate (DC) were used for the adsorption of cationic Red X-GRL from aqueous solutions. Mono-factor experiments were carried out to investigate the effects of the operation factor, and adsorption kinetics, isotherms, thermodynamics and mechanisms were explored. Similar trend for X-GRL adsorption onto RD and DC was observed. The adsorption capacity of dyes increased slightly with temperature, and the neutral pH was the optimum level. The adsorption processes occurred in accordance with the pseudo second-order model and were well fitted by the Langmuir isotherm model. The main driving forces of the physical adsorption on the diatomite were electrostatic attraction and van der Waals force. The RD could uptake more X-GRL than DC due to its higher content of fine particle and therefore, due to higher surface area available for adsorption. Raw diatomite as a cheap absorbent for X-GRL removal can be suggested as a promising supplement to activated carbon.

Opis:
Fine needle aspiration cytology (FNAC) is considered as the gold-standard diagnostic test in the diagnostics of thyroid nodules. It is a cost-effective procedure that provides specific diagnosis rapidly with minimal complications. It plays an important role in the determination of treatment - patients with suspected malignancy diagnosis can be subjected to surgery. On the other hand, it can decrease the rate of unnecessary surgeries. Aim: The aim of this study was to evaluate and compare the correlation, accuracy of fine needle aspiration cytology (FNAC) in the diagnostics of thyroid lesions with the final histopathologic diagnosis based on the surgical specimens. Materials and Methods: In our study we performed a retrospective analysis of a case series of patients who had been admitted to the Department of Endocrine, General and Oncological Surgery of the Hospital of M. Kopernik in Łodź (Poland) between May 2016 and December 2017 and underwent FNAC with subsequent surgery. Cytological diagnosis was classified into six Bethesda categories. Results: On cytological examination, 1070/1262 cases were reported as benign, 49 as malignant and 143 as suspicious. On histopathological examination, 956/1070 cases were confirmed as benign but there were 114 discordant cases. Among the other cases histopathology diagnosis confirmed malignancy in 45/49 cases and 128/143 suspicious cases. The sensitivity and specificity were 60,28% and 98,05% respectively. False positive rate was 1.95% and false negative rate was 39.72%. The positive predictive value was 90.1% and negative predictive value was 89.35%. Accuracy of FNA in differentiating benign from malignant thyroid lesions was 89.46%.

This study showed that more hand errors occurred in the nondominant hand, extended arm, normal breathing and standing compared with errors in the dominant hand, flexed arm, inspire–hold and sitting, respectively. This study advised people to use their dominant hand, flex their arm, inspire and hold the breath and support their body while performing fine manipulation tasks. Finally, hand error varied dramatically across the participants, indicating the need to screen individuals for fine manual manipulation tasks.

Opis:
The literature of the Romantics, in the first part of the 19th century, is steeped in religious doubt. Moreover, the sacred was a taboo yet unavoidable subject especially in novels and short stories that were considered at the time profane genres. Romantic writers exploited certain covert strategies in order to speak of the unspeak-able and touch the untouchable. They resort, for instance, to their artistic culture with its centuries of pictorial tradition that render religious figures and events more familiar and accessible. Musset’s Le Tableau d’église, Vigny’s Daphné, and Gauthier’s La Toison d’or, all bear witness to a striking (meeting) harmony between iconoclastic and/or cavalier characters and sacred works of art that focus on the Passion. All three writers interweave aesthetic contemplation with mystical communion, thus revealing a new sense of the sacred that is often ambiguous, nay, subversive. And since sacred art is not in itself sacred, it allows writers to come very close to sacrilege in order to examine the fine line between the profane and the sacred.

Opis:
Stirred pulp-mixing is performed before coal flotation. In this study, a two-stage stirred pulpmixing tank was designed based on the single-stirred process to intensify the mixing effect of pulp and flotation reagents. A tank has a pitched-impeller opening-type turbine. Stirred pulp-mixing and flotation experiments were conducted on a sample of anthracite fine coal (-0.5mm) from the Xuehu Coal Preparation Plant in Henan Province, China. The results of the two-stage stirred pulp-mixing were compared with those of a single-stage stirred pulp-mixing in terms of flotation performance. Compared with the single-stage stirred pulp-mixing, two mixing areas and double-layer impeller were able to strengthen the energy input to the stirred system, thereby improving the mixing efficiency of flotation reagents and coal particles in the pulp. The two-stage stirred pulp-mixing significantly increased the flotation feed rate of the cyclone-static micro-bubble flotation column and concentrate yield, enhanced the combustible matter recovery effect of coarse particles at a suitable flotation feed rate, and ensured the recovery effect of fine particles at high flotation feed rate.

Opis:
In the late 1990s, Stephan G. Schmid published a chronological typology of Nabataean Painted Fineware (NPFW) that was widely accepted by scholars of Nabataea and Roman Arabia. Tali Erickson-Gini has since raised concerns about parts of his NPFW typology, specifically related to two decoration types dating to the end of the 1st century and the beginning of the 2nd century CE (Dekorphases 3b and 3c). This article is a response to Erickson-Gini’s critique, published in this volume. We find that there is sufficient evidence to broadly validate Schmid’s proposed dating for the beginning of production of Dekorphases 3b and 3c to the late 1st century and early 2nd century CE, respectively.

Opis:
Niniejsza praca jest poświęcona pewnym zagadnieniom związanym z przesiewaniem drobno- i bardzo drobnouziarnionych materiałów sypkich. Jest to najtrudniejszy proces przesiewania (obok odsiewania materiałów wilgotnych), który w praktyce przemysłowej nie doczekał się jednoznacznego rozwiązania. O ile w przemyśle światowym rozpowszechnione są typowe przesiewacze jednopłaszczyznowe (zwane niezbyt precyzyjnie przesiewaczami wibracyjnymi) oraz znane są właściwości procesowe tych maszyn, o tyle do przesiewania drobnoziarnowego stosuje sie różne maszyny przesiewające, które nie zawsze sprawdzają się w warunkach przemysłowych. Artykuł niniejszy jest dyskusyjny, stanowi on przyczynek do nieco innego niż dotychczas, spojrzenia na proces przesiewania. Zawiera ponadto pewne uwagi praktyczne, spełnienie których jest ważne dla procesu przesiewania drobnoziarnowego. Druga część artykułu poświęcona jest maszynom przesiewającym opracowanym przez autora. Są to rozwiązania stworzone głównie z myślą o odsiewaniu materiałów drobnych. W tej części omówiono ważność prawidłowego zasilania przesiewaczy nadawą (materiałem przeznaczonym do przesiewania). Szczególną uwagę zwraca się również na napędy (głównie rotacyjne - wały niewyważone), od których w istotnym stopniu zależny jest efekt procesowy.
This paper is dedicated to some problems of screening of fine- and very fine-grained loose materials. This is the most difficult screening process (beside screening off wet materials), which in industrial practice has not been solved yet. As far as in the world industry typical single-plane screens are very popular (they are named, not very precisely, the vibrating screens) with known process properties, for screening of fine-grained material various screens are used which prove not always the most efficient in industrial conditions. The present paper is debatable, and can be treated as a contribution to a slightly different approach to screening than that represented so far. Additionally, it presents some practical recommendations which are important for fine screening process. Second part of the paper is dedicated to screening machines developed by the author. These are design solutions proposed mainly for screening of fine-grained materials. In this section the importance of correct feed supply to the screen is discussed. Special attention is given to drives - mainly rotational (unbalanced shafts), on which the process efficiency depends greatly.

The present study focuses on comminution of calcite powder in water media by ultrasonic treatment and the effect of some operational parameters such as treatment time (5–30 min), ultrasonic power (30-100% as amplitude), solid ratio (5-30% w/w), probe positions (0.5-2 cm) and cycle on the product size. Experimental results were evaluated on the basis of average particle size (d50). Sonication of calcite produced a drastic particle-size reduction (d50=12.89 μm) under optimal conditions.

The development of mining and processing industries is accompanied by the formation of fine-grained waste materials that must undergo the treatment. Sometimes, grinding materials is a prerequisite for further processing. The issues of coal dust and fine coal granulation conducted to obtain homogeneous and persistent pieces for application in various branches of industry were presented. The article describes the binders and additives were applied in order to change the properties of the granules. The key factors affecting the process of fine-grained coal granulation is discussed. Granulated coal dust is most useful as an alternative fuel for combustion in industrial and household heating systems. However, carbon fuel requires a systematic control of the mechanical strength and resistance to external factors.

Opis:
The article analyses the definition of “an item of fine art” and its practical application in the spectrum of insurance relationships. The definition is considered from a general point of view as well as from the legal perspective. It is also collated with synonymous concepts (i.e. antiquity, cultural property, exhibits) and briefly examined in different legal contexts (fiscal, administrative, international, civil). This review leads to a conclusion that it is impossible to find a satisfactory and generally applicable definition of “an item of fine art,” and that therefore searching for such a definition is a waste of time. On the other hand, attempts to define “an item of fine art” shed light on its classic features, which may be useful in certain cases.The article draws attention to the indirect impact of certain reflections and observations regarding “fine art,” notably their effect on the interpretation of the concept of “items of fine art” in civil law and civil contracts. It also shows that an accurate definition may be essential in an insurance relationship, since the subject of insurance protection has to be clearly defined. These practical implications apply particularly to situations when an item of fine art is not the sole object of insurance protection and when it is an element of an insured collection.The article considers not only the applicable legislation but also the general terms and conditions used by insurance companies.

Opis:
This study aimed to investigate controlled fermentation of cocoa beans with selected yeasts as starter cultures via integrating microbiological, biochemical, and chromatographic analyses. The steps involved in the yeast starter culture test were of the following order: 1) counting, isolation, purification, and biochemical identification of yeasts, 2) selection of ethanol-producing yeasts, 3) selection of thermotolerant yeasts, and 4) evaluation of physicochemical parameters of the selected yeasts in controlled fermentation of cocoa (F1 - Saccharomyces ssp. and Hanseniaspora ssp. and F2 - spontaneous fermentation - control). A total of 32 yeasts were isolated from three sampling points (M1, M2, and M3), which comprised 50% Candida ssp., 9.4% Rhodotorula ssp., 18.8% Saccharomyces ssp., and 18.8% Hanseniaspora ssp. The yeasts identified as Saccharomyces ssp. (n = 6) were subjected to the ethanol production test. Saccharomyces spp. CLV09 showed the highest concentration of ethanol in the simulated cocoa medium (3.5% v/v). Hanseniaspora spp. CVL20 and CVL19 strains showed the highest thermotolerance at 42°C after 72 h of growth. The starter cultures with Saccharomyces ssp. and Hanseniaspora ssp. showed a similar growth rate of the mesophilic aerobic population in both F1 and F2. Fermentation of the starter culture showed a higher production of organic acids than spontaneous fermentation (F2). Thus, Saccharomyces ssp. and Hanseniaspora ssp. can be used as a starter culture in cocoa fermentation.

Opis:
W artykule przedstawione zostały zagadnienia dotyczące drobnoziarnistych odpadów z procesu wzbogacania węgla kamiennego. Przedstawiono przykładowe wyniki badań drobnoziarnistych odpadów z trzech stawów osadowych mułów węgla energetycznego i jednego osadnika odpadów flotacyjnych węgla koksowego oraz ze zbiornika wodnego. Zaprezentowane wyniki badań pozwoliły na ocenę sposobu wykorzystania tych odpadów. W artykule przedstawiono również cel i założenia projektu rozwojowego pt.: "Identyfikacja potencjału energetycznego depozytów mułów węglowych w bilansie paliwowym kraju oraz strategia rozwoju technologicznego w zakresie ich wykorzystania" realizowanego przez Instytut Mechanizacji Budownictwa i Górnictwa Skalnego Oddział zamiejscowy :Centrum Gospodarki Odpadami" w Katowicach wraz z Katedrą Przeróbki Kopalin i Utylizacji Odpadów Politechniki Śląskiej.
In the article the issues related to fine tailings produced as a result of hard coal beneficiation process are presented. The amount of waste produced as a result of coal extraction, features of fine tailings and mineralogical-petrographic composition are given. Possible methods of fine tailings usage are also presented. Results of research of fine tailings from three coal slurry impoundments of energetic coal, one flotation tailings pond of cocking coal and one water pond are shown. Presented results allow to assess the possibility of tailings usage. It was demonstrated that coal slurries from energetic coal can be used as a fuel for fluidized bed combustion. The results of research show that it is possible to reprocess flotation tailings stored for a long time in a pond using again flotation methods. It is necessary however to choose the right froth agent and its proper concentration in a process. It was also demonstrated that tailings deposited in a water pond have properties that allow their energetic usage. The purpose and assumptions of a new development project "Identification of energetic potential of coal slurries deposits in national fuel balance and strategy of technological development in the range of their usage" carried out by Institute of Mechanized Construction and Rock Mining division "Centre of Waste Disposal" in Katowice in cooperation with Department of Mineral Processing and Waste Disposal of Silesian University of Technology are presented. The purpose of a Project is to assess the possibility of including existing coal slurries deposits into national fuel balance. A project is in accordance with 2006/21/WE Directive of European Parliament and Commision regarding the management of waste from extractive industries and Act from 10th of July 2008 (Dz.U. z 2008 r. Nr 138, poz.865) regarding extractive waste that transposes Directive 2006/21/WE into Polish regulations.

Opis:
The article identifies the main characteristics and features of the artistic arrangement of representative public buildings in Vienna that influenced analogical objects of Lviv in the second half of the 19th century. The issue of Vienna’s historicism and its peculiarities in interior decoration are also considered. The research involved selecting and analyzing key public buildings that are present in both cities, such as theaters, universities, the Diet (in case of Vienna – the Parliament), museums, courts and other sites with a broad representative group of rooms. These revealed common trends, direct and indirect quotations, both in artistic elements and in the overall order composition. The article also explores major public buildings in Vienna along with architects who have become role models and set some standards for the artistic design of the representative group of rooms. As a result, the influencing factors were identified, among which administrative, educational, cultural and economic issues are highlighted and reviewed.

Opis:
In response to the problem of environmental protection, the electronic industry is studying the lead-free alloys as substitutes for lead-containing solder alloys. At the same time, with progress in electronic devices in recent years, smaller size and higher precision are strongly demanded in electronic board connections. Therefore, it is necessary to prepare fine powders of solder paste for these connections. To produce such lead-free solder balls, a novel powdermaking process, “hybrid atomization” that combines gas atomization and centrifugal atomization, was used. This technique produces very fine and spherical tin alloy powders with a mean diameter of about ten micrometers and very narrow size distribution with few satellites at low production cost. Taking a Sn-9mass%Zn alloy as an example, process experiments were carried out, and the effect of temperature, spray distance and disk rotating speed on the resultant powder properties were examined. The optimal processing conditions were determined from the results; the influences of the processing parameters on the properties of the obtained powders were quite different from those in the conventional atomization processes. The spherical powder with a mean diameter of 10.6 žm and a standard deviation of 1.3 ~ 1.7 was obtained in the determined optimum condition.

Opis:
Cochliopodium megatetrastylus n. sp. is described based on light microscopy, fine structure and molecular genetic evidence. Amoebae are broadly oval to somewhat triangular during locomotion with average length of 37 μm and breadth of 50 μm, and surrounded by a hyaloplasm margin, somewhat narrow when at rest but more expanded during locomotion (~ 5–10 μm at the anterior). Sparsely occurring subpseudopodia, barely emergent from the hyaloplasm, are blunt and finger-like, occasionally becoming adhesive laterally or at the posterior. Cysts develop after 2–3 weeks in culture and are round with a distinct margin, decreasing in size from 20 to 5 μm during maturation. The granuloplasm contains refractile crystals. A vesicular nucleus (~ 6 μm), containing a nucleolus (2–3 μm), is variable in shape from somewhat lenticular in section to irregularly rounded with undulating or lobed margins. Surface scales (~ 0.3 μm in height) have an apical deeply concave funnel-like collar (~ 0.15 μm deep), without a spine, composed of radial fine rays and concentric filaments forming a finemesh, supported on four non-cross-linked styles (~ 0.2 μm apart) attached to a round to broadly angular base plate (0.6–1 μm) with a fine gridtexture. Cysts are rounded and enclosed by an organic wall bearing remnants of the scales on its outer surface. Both concatenated analysis of SSU-rDNA and COI genes and comparative morphologies support the designation of Cochliopodium megatetrastylus n. sp. as a new species.

Opis:
Although Nabataean Painted Fine Ware (NPFW) has been examined in light of Stephan Schmid’s chronological typology since the late 1990s, few stratified contexts with NPFW from outside Petra have been published, and none derived from contexts occupied continuously from the Nabataean through Byzantine periods. Questions remain about the dating of later dekorphases (3–4) due to a lack of contexts. This paucity is remedied, however, by Area K at Roman Aqaba/Aila, Jordan. Area K was a domestic complex, just inside the later Byzantine city wall, excavated from 1994 through 2002. Using associated numismatic evidence and imported fine wares (primarily Eastern Sigillata A and African Red Slip), this paper argues that NPFW Dekorphase 3b appeared at Aila in the second half of the 1st century CE, and Dekorphase 3c appeared shortly afterwards, around the time of the Roman annexation in the beginning of the 2nd century.
