Opis:
The sealing of shaft cast iron tubing within a tubing Inter-rib niche is often needed during overhauls and repairs of a shaft lining. Leakages or scratches and fractures can occur within the area of individual tubing of the shaft lining. The Przedsiębiorstwo Budowy Szybów S.A. developed special method for the sealing in question. Around the sealed area, a closed circumference groove of a depth smaller than the tubing thickness is made in the inner shaft lining. The sealing element is placed in this groove and then tightened with a spatial insert, with a hole for the injection of the sealing medium. A specially designed milling machine is used for groove making in the tubing lining of the mine shaft. The milling machine is composed of: power transmission system, special construction for mounting the milling machine to tubing and advance mechanism. The milling machine is driven by a battery drill-driver, and the whole device is mounted to the tubing with the use of specially designed guides with handles.

Opis:
Diabetic retinopathy as a complication of diabetes is one of the most common causes of vision loss. It is a dangerous disease, which affects more and more people. It is important to know its different causes, background and to generate new, effective therapeutic threatments. One of the possible causes of diabetic retinopathy is the accumulation of advanced glycation products and over-expression of AGEs receptors (RAGE) leading to tissue damage, oxidative stress formation, and the promotion of other changes and disorders. There are many genetic variants that encode the AGEs receptor (RAGE). Some polymorphisms (Gly82Ser, 1704G/T, 2184A/G, -429T/C, -374T/A) may be associated with diabetic retinopathy. This paper aims to systematize knowledge in this field and to show the relationship between these compounds and diabetic retinopathy.

Opis:
This work presents an innovative shaft-lining solution which, in accordance with a patent of the Republic of Poland, allows successive, periodic leaching of excess rock salt migrating to the shaft opening. As is commonly known, all workings in rock salt strata are exposed to an increased convergence of sidewalls, making it very difficult to use shafts properly. Rocks migrating towards the shaft opening cause very high stress on the shaft liner. As a result, if the lining does not show substantial deformability, it fails. Lining failure due to insufficient deformability has been extensively described in the literature. Also, throughout the history of mining construction, a number of solutions have been proposed for different types of lining-deformability enhancement. For instance, the KGHM mining corporation applied a deformable steel lining – a solution used in the mining construction of galleries – along a 155-m-long section of the SW-4 shaft with diameters of 7,5 m that passes through a rock salt strata. At KGHM, the SW-4 shaft passes through a rock salt strata along a section of 155 m, in which a deformable enclosed steel lining was made. After several years, the convergence of shaft sidewalls stabilised at a rate of 0.5 mm/day. This enormous activity of the rock mass made it necessary to reconstruct the entire shaft section after only four years. According to further predictions, it will be necessary to reconstruct this section at least four times by 2045. This paper discusses in short form the underlying weaknesses of the technology in question. As a solution to the problems mentioned above, the authors of this work present a very simple design of a shaft lining, called the tubing-aggregate lining, which utilises the leachability of salt rock massifs. The essential part of the lining is a layer of coarse aggregate set between the salt rock sidewall and the inner column of the tubing lining. One the one hand, coarse aggregate supports the salt rock sidewall and is highly deformable due to its compressibility, but on the other hand it allows water or low saturated brine to migrate and dissolve salt rock sidewalls. This paper presents the first stage of works on this subject. Patent No. PL 223831 B had been granted before these works commenced.
Praca niniejsza prezentuje innowacyjne rozwiązanie obudowy szybu, która zgodnie z patentem RP umożliwia sukcesywne okresowe ługowanie nadmiaru soli migrującej w światło szybu. Powszechnie wiadomo, że każde wyrobisko górnicze w górotworze solnym narażone jest na zwiększoną konwergencję ociosów, co w przypadku szybów jest dużym utrudnieniem prawidłowego ich wykorzystywania. Migracja skał w światło szybu powoduję bardzo wysokie obciążenie deformacyjne obudowy. Jeżeli ta nie ma zdolności do znaczącego odkształcania się to ulega zniszczeniu. Literatura fachowa dysponuje wieloma opisami zniszczenia obudowy zbyt mało podatnej. W historii budownictwa górniczego zaproponowano też kilka rozwiązań w postaci różnego rodzaju upodatnienia obudowy. Przykładowo, przenosząc z budownictwa górniczego wyrobisk korytarzowych konstrukcję obudowy stalowej podatnej w KGHM w szybie SW-4 na odcinku o długości 155 m, przechodzącym przez górotwór solny, zastosowano podatną obudowę stalową zamkniętą. Konwergencja ociosów szybowych w tym przypadku po kilku latach ustabilizowała się na poziomie 0,5 mm/dobę. Efektem tak wielkiej aktywności górotworu była konieczność przebudowy całego odcinka szybu już po 3 latach. Dalsze prognozy przewidują, że do roku 2045 konieczna będzie jeszcze co najmniej 4 krotna przebudowa tego odcinka. W pracy przedstawiono zasadnicze słabości tego rozwiązania technicznego. W odpowiedzi na tego typu przypadki Autorzy niniejszej pracy prezentują bardzo prostą konstrukcje obudowy zwanej obudową „tubingowo-kruszywową”, która wykorzystuje zdolność górotworu solnego do procesu ługowania. Istotą tej obudowy jest warstwa kruszywa gruboziarnistego, umieszczona pomiędzy ociosem solnym i wewnętrzna kolumną obudowy tubingowej. Kruszywo gruboziarniste z jednej strony podpiera ocios solny z możliwością znacznego odkształcania się bo jest ściśliwe, ale z drugiej strony pozwala na migrację wody słodkiej, która będzie oddziaływać na ociosy solne rozpuszczającje. Niniejsza praca poprzedzona przyznanym patentem nr PL 223831 B, prezentuje pierwszy etap prac nad tym zagadnieniem. Etapem drugim były badania intensywności ługowania i możliwości zastosowania tego rozwiązania w budownictwie szybowym. Etapem finalnym winien być odcinek badawczy szybu w górotworze solnym z obudową pozwalającą na okresowe ługowanie calizny solnej.

Opis:
On the basis of the registered indications of the water meter, a study on the size and variability of water consumption on the WULS campus in the academic years 2012/16 is presented. The average specific water consumption at a time when classes are implemented amounted to 26.6 dm3 per student per day for full-time studies student and 19.7 dm3 per student per day for the student part-time studies. During the holiday season, the rates are lower at 18.4 and 11.8 dm3 per student per day, respectively. These ratios were determined without taking the water consumption in the dorms into account. The daily peaking factor amounted (Nd) to 1.36, while the hourly peaking factor (Nh), reached 1.71. Within the week cycle, the highest water consumption was observed in Tuesdays and the lowest – in Sundays. The average Tuesday demands are 40% higher than the Sunday demands. The water consumption peaks during the day occur between 11 a.m. and 1 p.m. as well as 11 p.m. and 1 a.m. The hourly structure of the water distribution in the WULS-SGGW campus is similar to the weekend structure of water distribution in multi-family residential buildings, with the exception of the later occurrence of the evening summit.

Nowadays, high-precision machines require lightweight materials with very high strength. Ion implantation is used to improve the mechanical strength of the material. A further paper presents the influence of manganese and nitrogen ion implantation on changes of microhardness of the surface layer of cobalt alloy. Samples were analyzed with the SEM-EDS Phenom ProX microscope. Microhardness was assessed with the Vickers method, and the loads of 1 gf (0.00981 N) and 5 gf (0.049 N) was applied using a FM-800 from Future-Tech microhardness meter. At a load of 1 gf, the penetration depth of the implanted specimens was reached not exceeding 0.5 um. At this depth, all samples showed an increase in microhardness compared to the unimplanted sample. The highest increase in microhardness was achieved after implantation of Mn ions with dose D=1∙1017 Mn+/cm2 and energy E=175 keV. The increased load on the indenter to 5 gf reduced the microhardness differences between implanted and unimplanted samples.

Degradation of the environment is nowadays believed to be the most alarming problem that needs to be solved. Global warming and environmental pollution are predicted to cause a catastrophic chain reaction leading to species extinction, mass emigration due to rising sea levels and global crisis. The only solution suggested by international organizations is the immediate reduction of greenhouse gases and other harmful substances. Marine transportation harmful substances into the atmosphere are recognized to be a significant source of global atmospheric pollution. Despite the high efficiency of marine diesel engines, their impact on the environment is considerable. Due to environmentally friendly policies, modern engines concerns about not only efficiency but also mainly about s aspects. This article analyses and compares marine s exhaust gases reduction methods. Especially the most harmful substances emitted by ships were taken into consideration. The article presents the most crucial law regulations of harmful substances to the atmosphere, pointing at actual and possible future implementations. The most complex methods allowing meeting the latest limits were presented. Pros and cons of available control methods were thoroughly described and methods were compared. The most adequate methods form the effectiveness and economical point of view was pointed out.

The main element of genomic molecular analysis is isolation of DNA from biological material. DNA isolation is an important process of PCR methods. Efficency of PCR processes depends of purness and concentration of DNA. Many methods allows to izolate good quality DNA. There are many Purification Kits and methods of extraction genomic material. We show available techniques and methods of increasing efficiency of the process in our studies. Previous data shows that operating with kits needs optimization, whilst protocols do not have all information about isolation process. We concentrate on Epicentre MasterPure DNA Purification Kit, which is cheap, fast and allows to purification nucleic acids from various materials. We show detailed advantages and disadvantages of this set. Our main aim is to develop protocol to get optimal concentration (50-100 ng/μL) and pureness (A 260/280; 1.6-1.9) of DNA. We also should optimize the process of DNA isolation to obtain efficiency of about 100%. Optimized methodology of DNA isolation, with using MasterPure DNA Purification Kit allows to get good quality material in laboratory without specialistic equipment. This survey contains our assumptions of ways how we can influent on purification process according to previous data.

In the last decade evolution of the requirements for training and professional competences of ship’s crewmembers, including ship engineers can be observed. Despite the implementation of training programs according to IMO requirements in maritime training centres, a different level of competence of young people beginning their professional career on ships in the engine department is observed. The article discusses general conventions, goals, and effects of the "BS Cadet Program" training program, introduced by one of the larger German ship-owner to improve the competencies of crewmembers at the operational level, who will take duties of the watch engineer in the ship engine room soon. General idea of this training program is reducing the time of the path career what is a standard in most shipping companies. Such idea in this program is utilised by directly merging theoretical knowledge with professional practice on special prepared training vessel. The work present also comparison of the acquired knowledge verification results of training participants with the results of engine cadets from last semester of the UMG Faculty of Engineering. The comparison includes computer exercises of Marine equipment and machineries (UNITEST Company – CBT) also genera ship and engine room knowledge checked by written test called “Final Test” carried out on the end of 3 months training.

Opis:
The objective of this study was to determine changes in fuel delivery rate by common rail system injectors during their simulated operation on a test stand. Four Bosch injectors used, among others, in Fiat 1.3 Multijet engines were tested. The injectors were operated on a test rig at room temperature for 500 hours (more than 72 million work cycles). During the test, pressure and injection frequency were changed. Changes in the operating parameters were estimated based on obtained injection characteristics and effective flow area determined thereby. The observed changes in fuel delivery rate were compared with results of the surface analysis of control valves and nozzle needles. Despite the stated lack of wear, significant changes in the dynamics of injector operation were observed, particularly at short injection times. Small pilot injections cannot be corrected by the fuel injection control system because they do not affect the changes in torque; however, they do affect the combustion process. This creates conditions for increased emission of toxic exhaust components.

Objectives Atmospheric pressure is the most objective weather factor because regardless of if outdoors or indoors it affects all objects in the same way. The majority of previous studies have used the average daily values of atmospheric pressure in a bioclimatic analysis and have found no correlation with blood pressure changes. The main objective of our research was to assess the relationship between atmospheric pressure recorded with a frequency of 1 measurement per minute and the results of 24-h blood pressure monitoring in patients with treated hypertension in different seasons in the moderate climate of the City of Łódź (Poland). Material and Methods The study group consisted of 1662 patients, divided into 2 equal groups (due to a lower and higher average value of atmospheric pressure). Comparisons between blood pressure values in the 2 groups were performed using the Mann-Whitney U test. Results We observed a significant difference in blood pressure recorded during the lower and higher range of atmospheric pressure: on the days of the spring months systolic (p = 0.043) and diastolic (p = 0.005) blood pressure, and at nights of the winter months systolic blood pressure (p = 0.013). Conclusions A significant inverse relationship between atmospheric pressure and blood pressure during the spring days and, only for systolic blood pressure, during winter nights was observed.

Opis:
When we assume that a survey reveals respondents’ true attitudes we tacitly assume that the subjects understood what we are asking them about and that they had no incentive to be untruthful. In typical studies none of the two assumptions holds. Subjects are asked questions that use undefined terms and they are asked about issues they have no incentive to answer truthfully. Here we argue that a way to solve the two problems lies in constructing a formal theory of an attitude in such a way that an attitude can be derived from the answers yet when answering the questions subjects cannot possibly know that their responses reveal anything about their attitude and, hence, they have no incentive to answer insincerely.We briefly discuss a study that has the desirable properties necessary for the proper design.

Distances to cover are still growing in Polish coal mines. It is not a real issue in terms of material and staff transport, which commonly uses suspended monorails with a friction wheel drive. The problem is how to transfer single people and small loads behind the scheduled times and routes of monorails. The goal of this work was to design and construct an individual mean of transport with its own drive using a monorail track which would meet the requirements of law, safety, mobility and can be used behind the scheduled times of monorails.
