Opis:
Water-miscible metalworking fluids are an essential component of many manufacturing processes. During their lifetime they are subject to permanent changes in their physical and chemical characteristics. Due to their high content of water and their chemical composition in use, metalworking fluids (MWF) are prone to microbial life, i.e. the proliferation of bacteria and fungi. The microbial activity leads to significant changes in the chemical composition of the MWF, which can result in the loss of their technical properties. This paper briefly discusses the influences of microbial contamination on the technical quality of MWF and presents common monitoring systems for the detection of microorganisms. Finally, measures are described that can be taken to protect MWF from damage caused by high microbial loads in daily practice. In a short outlook, alternative research approaches are mentioned that aim at sustainable use of MWF.

Opis:
Fiheries products that will be exported or marketed domestically, must have the specified food safety criteria. One of the criteria that the products is safe to be marketed and consumed is free from the presence of pathogenic bacteria. One of the common pathogenic bacteria found in food is Vibrio cholerae. The purpose of this research aims to examine, isolate and confirm the presence of dangerous pathogenic bacteria V. cholerae which shouldn’t exist in fisheries products with sample Frozen cuttle fish, frozen baby octopus small cut and Pasteurized crab meat. This research was held from July-August 2018 at Cirebon Test and Application of Fishery Products Technical Unit Agency. Data is collected through direct observation or testing in a microbiology laboratory with conventional methods using special media for V. cholerae such as Alkaline Peptone Water (APW) and Thiosulfate Citrate Bile Salts Sucrose (TCBS). The testing is qualitative, so the results obtained are either positive or negative. The results of the research showed that there’s no pathogenic bacteria V. cholerae were found in tested fisheries products so that they were safe to consume and satisfied the standards to be marketed.

Opis:
Celem pracy była ocena stanu mikrobiologicznego wody z 6 krakowskich fontann oraz stworzenie na tej podstawie rankingu czystości fontann. Ocena ta obejmowała analizę liczby bakterii psychrofilnych i mezofilnych, bakterii z grupy coli, bakterii grupy coli typu kałowego, Escherichia coli i paciorkowców kałowych. Wyniki zostały odniesione do stosownych aktów prawnych. Wykazano znaczne zanieczyszczenie wody z badanych fontann. W pięciu z sześciu fontann woda była niezdatna do kąpieli, we wszystkich do picia. Najmniej zanieczyszczona była woda z fontanny na pl. Szczepańskim, najbardziej zanieczyszczona z fontann przed Uniwersytetem Rolniczym i w parku Krakowskim.
Public fountains of various architectural forms had already been known in ancient Persia. Their abundance greatly increased in the times of ancient Rome and Greece, where they decorated public gardens, parks and thermal baths. They currently still play an important role as a part of street furniture, but also provide the possibility of cooling down in their vicinity or even in the water from the fountain on hot summer days. The aim of this study was the assessment of microbiological quality of water from 6 fountains of Krakow and the creation of the purity ranking of the Krakow fountains. This assessment included the total number of psychrophilic and mesophilic bacteria, coliforms, fecal coliforms, Escherichia coli and fecal enterococci. The results were referred to the relevant standards. The results of the study demonstrated a significant pollution of water from the analyzed fountains. Water from five of the six fountains was unsuitable for bathing purposes and from all for drinking. Water from the fountain on the Szczepanski Square was the least contaminated, while the most polluted were the ones from the fountains in front of the University of Agriculture and from Krakowski Park.

Opis:
Periprosthetic joint infection is one of the complications developing after surgical implantation of the prosthetic joint. Combined with ageing of society, number of arthroplasties will grow. Knowledge of risk factors of PJIs (periprosthetic joint infections) is essential for surgeons performing such interventions. There are many groups of risk factors. Patient’s race does not clearly predispose to developing PJIs. Age is not a key factor of occurrence of PJIs. Sex of patient plays important role (more PJIs in male patients )when there are no additional risk factors such as comorbidities – in that case females are suffering from PJIs more often. Alcohol intake is not clearly correlated with increased risk of PJIs while tobacco smoking and higher BMI increased that risk significantly. Cardiovascular, pulmonary tract, renal, gastrointestinal, rheumatological and oncological diseases are important PJIs risk factors as well as as diabetes, immunosuppression, preoperative infection and depression. Such complications are also bond with higher ASA score, some of the lab test results. Last group of risk factors is related with treatment – complications during surgery, other conditions like hypothermia, longer hospital stay, blood transfusion and reoperations. It is vital to acknowledge these risk factors and manage to remove these related to surgeon while encouraging patient to deal with these related to him.

Opis:
Mikroorganizmy są nieodłączną składową otaczającego nas świata – również człowieka. Nie występują przypadkowo, ale jako wieloelementowe konsorcja zamieszkujące określone siedliska, tworzą mikrobiomy. W dobie najnowszych doniesień naukowych oraz niepohamowanego przepływu informacji, zdajemy sobie sprawę z tego, że mikroorganizmy pełnią ważną, choć nieuchwytną, rolę w naszym życiu. Mikroorganizmy stanowią o jestestwie człowieka – bez mikrobiomu, człowiek jest jałową planetą skazaną na zagładę. Jak ważna jest rola mikrobiomu, jak dalekosiężne w skutkach jest zachwianie w nim równowagi – to nie jest już tak oczywiste. Człowiek ostatecznie został strącony z piedestału władcy stworzenia – biologiczne fakty dokładają kamyczek do ogródka posthumanizmu. Mikrobiom to nie są organizmy obok – biernie wykorzystujące człowieka jako niszę ekologiczną. To mikrobiom pomaga człowiekowi trawić, walczyć z infekcjami, a także, co mniej oczywiste, wpływa na jego zachowanie. Człowiek nie istnieje obok milionów mikroorganizmów, ale to wespół z nimi jest tym, kim jest. Nie jesteśmy z milionami; jesteśmy milionami. W niniejszym wywodzie zamierzam przybliżyć złożoną tematykę ludzkiego mikrobiomu. Ukażę te oczywiste oraz te mniej oczywiste ekosystemy planety Człowiek. Pokażę również niezwykłą, często wielopoziomową sieć oddziaływań rządzącą tym światem. Poznanie ludzkiego mikrobiomu nie byłyby możliwe bez najnowszych zdobyczy techniki, dlatego przedstawię również wyzwania, które stawia metodologia tych badań. Wydaje się to istotne w kontekście możliwości transmisji tej tematyki na pole bio artu.
Microorganisms are an inseparable component of the world around us, including humans. They do not occur randomly, but they form multi-element consortia inhabiting specific habitats, they form microbiomes. In the era of the latest scientific reports and the unrestrained flow of information, we realize that microorganisms play an important, though elusive, role in our lives. Microorganisms constitute the human being - without a microbiome, the human is a barren planet condemned to destruction. It is not so obvious how important the role of the microbiome is, and what are the consequences of an imbalance in it. The human is finally knocked down from the pedestal of the ruler of creation - biological facts are added to posthumanism. Microbes are not organisms living next to us, passively using humans as an ecological niche. The microbiome helps human to digest, fight infections and, what is less obvious, affects his behaviour. Humans do not merely exist next to millions of microorganisms, but together with them, he is who he is. We are not with millions; we are the millions. In this article, I intend to introduce the complex topic of the human microbiome. I will describe the obvious and less obvious ecosystems of the planet Human. I will also show the unusual, often multi-level network of interactions that rule this world. Getting to know the human microbiome would not be possible without the latest technological achievements, so I will also present the challenges posed by the methodology of this research. It is important in the context of the possibility of transmitting information on this topic to the bio art.

Opis:
One of the most frequently implemented processes in the water treatment technology is filtration through a biosorption bed. The techniques based on biochemical processes involving bacteria result in obtaining high quality of water. There are a number of different materials used as the filler material for biological filters. Carbon deposits are the most popular, due to their high effectiveness. The problem with the use of this process is the leaching of microorganisms from the biofilm and the biological stability of water thus obtained. There is a need to develop quick methods to assess the microbiological quality of this water. Modern techniques for determining the amount of microorganisms, such as flow cytometry and luminometry may be the right tools. The water collected for testing came from the Water Treatment Station located in the Podkarpackie voivodeship. The microbiological tests carried out in the analyzed water samples collected after the filtration process on granular activated carbon. Both traditional culture method and modern techniques used to determine the number of microorganisms (flow cytometry, luminometric ATP assay) demonstrated an increase in the number of microorganisms in the examined waters (in the water after the filtration process and in the water introduced into the water supply network) after the incubation process for 3 and 7 days at 15 and 22°C.

The paper presents the examples of damage of elements caused by incorrect assessment of pipeline work conditions. The presented damage cases resulted in the need to replace pipelines. This work is an analysis pertaining to the impact of chemical and microbiological synergy of corrosion on stainless steel pipelines. The paper investigates the corrosion mechanisms that may occur under normal operating conditions at each water treatment station, and the methods of counteracting the corrosion were indicated. The analysis of the corrosion mechanisms was formulated taking into account the design stage, – the correctness of the steel grade choice by the designer, the stage of implementation – the most common implementation errors, and the operational stage – optimization of the technological system work and the effects of the introduced changes. The analysis was carried out at a water treatment plant in Poland with a maximum flow of 20,000 m3 a day-1, which draws raw water from deep water intakes and from a surface intake. The treatment technology includes an aeration system (aeration) and a two-stage treatment process using sand and carbon filters. The disinfection process and prophylaxis in the water treatment plant is based on the use of chlorine gas.

Opis:
The absence of even a single finger results in a major impairment in the hand function (precise grasping, grip power), therefore significantly affecting the social and professional life of victims who are frequently young people. Finger amputation is a surgical treatment for ~69.000 patients in the EU after traumatic injury, in which replantation microsurgery fails due to the severity of tissue damage. The surgical reconstruction is currently possible only via autograft transplantation, e.g. a toe-to-hand transfer, thus leading to foot impairment. Some motion functional restoration is also possible using a bone-anchored silicone prosthesis but without the sense revalidation. Our current research focuses on alternatives for surgical reconstruction by means of novel patient- -specific, durable, biomimetic, bioactive and antibacterial implants for reconstructing lost bone and joints. The implant design – and the improved micro(neuro) surgery (beyond the project) – will consist in the fast successful rehabilitation, including the soft-tissue related mobility, the implantation of state-of-the-art nerve conduits as well as the aesthetic appearance. Key issues for the long-term functionality of the biomaterial-based reconstruction of hard tissue are based on surgical demands, such as: (1) perfect integration of a bone-substituting metal with the surrounding bone tissue (a) with no signs of loosening due to stress shielding at the interface and (b) enhanced with protective activity against bacterial inflammation (antimicrobial properties and formation of vascularized bone tissue (ossification)) even months to years after the injury; (2) biomimetic finger joints based on non-wearing materials without ossification meant to prevent the loss of the motion function.

Opis:
Mango cv. ‘Tommy Atkins’ is a highly appreciated fruit for its organoleptic characteristics and its resistance to minimal processing. However, some operations as peeling and cutting can generate microbial contamination and loss of bioactive compounds. Ultraviolet short wave (UV-C) is an alternative technology for fresh-cut products that leads to microbial inactivation and the increase of beneficial compounds. The effect of a UV-C dose of 6 kJ/m2 was evaluated on quality attributes of fresh-cut 'Tommy Atkins' mango during days 0, 3, 6, 9, and 12 of storage (5°C, relative humidity: 85-90%), and compared with a positive control (conventional method by immersion in 10 mg/L sodium hypochlorite solution) and a negative control (without treatment). Physicochemical analysis (titratable acidity, pH, total soluble solid content, and firmness), superficial color evaluation, determinations of microbial counts, contents of total carotenoids, phenolics and flavonoids, and antioxidant capacity assays were performed. The results showed that UV-C treatment allowed to preserve microbial safety and superficial color of stored fresh-cut mango, and to increase the content of total carotenoids, which was 19.34 and 26.50 mg β-carotene/100 g fresh weight (FW) for control and UV-C treated sample at day 12 of storage, respectively. The DPPH• scavenging activity of the UV-C treated mango was also higher (0.60 mM TE/g FW) compared to control (0.27 mM TE/g FW) at the end of storage. However, UV-C treatment caused loss of firmness. Some native microorganisms of mango adapted to the stress caused by the treatments and the storage.
