Vibration assessment of the consumption of a technical object

Machines in operation are subject to degradation controlled by diagnostic methods. The vibrodiagnostics is one of the machine condition description methods – understood as the organized set of methods and means to the technical state estimation (their causes, evolution and consequence) of technical systems, with utilization of vibration processes or the noise signal. Obtaining information on the condition and its processing for the purposes of legitimate exploitation decisions is elaborated on in many aspects, considered as new herein. This involves information selection, dedicated diagnostic systems, the system of agreeing on decisions, and cause-effect modelling. Selected aspects of this subject are discussed also in this publication

Low cost diagnostics system dedicated to rolling bearings

This article presents low cost diagnostic system, dedicated to rolling bearings. This system can be widely used in existing machines, to improve their reliability and reduce the costs of maintenance. Low cost electronics sensors, a few microchips, a multi-meter and a programmable micro-controller, which can send data to a computer, were selected. A computer is not necessary in this system, because data can be directly presented on LCD displays; moreover, alarm levers can be signaled with flashing lights and buzzers. This shows that an operational system can be produced with low cost, which is not obvious for managers and mechanical engineers

The risk of injury for daily training is very high. Volleyball is also an asymmetric sport, which further increases the risk of injury. Simple screening test, which is Functional Movement Screen, will reduce this risk, so I think that a lot of clubs will decide to implement of it.The main aim of this study is to present and compare the results of the functional assessment of motor and susceptibility to injury in female volleyball players and their interplay with injuries which happened in the last three years. Aim of the study was carried out based on the study material comprising a group of 15 women, practicing volleyball professionally. The research group age was between of 20-35 years.Material and Method:            Functional Movement Screen- functional screening was the research method.  It is using the seven tests which can assess the patient's/athlete’s basic movement patterns. All motion tasks are assessed on a scale 0 to 3. The players also filled the questionnaire.Results:Maximum disturbance revealed deep squat test. The smallest disorders showed shoulder mobility test for the left hand and in line lunge test for the left leg. Three of the five single limb tests showed asymmetry: hurdle step, deep squat, shoulder mobility. 53% of players have experienced a serious injury in the last three seasons.  The two players with the highest number of FMS points have not been seriously injured so far.Discussion and Conclusion:The consistency between the FMS test results and the frequency of injuries in II league female volleyball players was different, then in other studies.  For the participants deep squat was the most difficult test, over 50% of players had painful knees, average points in FMS test was 14,73

Constitutive activation of MET signaling impairs myogenic differentiation of rhabdomyosarcoma and promotes its development and progression

Rhabdomyosarcoma (RMS) is a soft tissue sarcoma, which may originate from impaired differentiation of mesenchymal stem cells (MSC). Expression of MET receptor is elevated in alveolar RMS subtype (ARMS) which is associated with worse prognosis, compared to embryonal RMS (ERMS). Forced differentiation of ARMS cells diminishes MET level and, as shown previously, MET silencing induces differentiation of ARMS. In ERMS cells introduction of TPR-MET oncogene leads to an uncontrolled overstimulation of the MET receptor downstream signaling pathways. In vivo, tumors formed by those cells in NOD-SCID mice display inhibited differentiation, enhanced proliferation, diminished apoptosis and increased infiltration of neutrophils. Consequently, tumors grow significantly faster and they display enhanced ability to metastasize to lungs and to vascularize due to elevated VEGF, MMP9 and miR-378 expression. In vitro, TPR-MET ERMS cells display enhanced migration, chemotaxis and invasion toward HGF and SDF-1. Introduction of TPR-MET into MSC increases survival and may induce expression of early myogenic factors depending on the genetic background, and it blocks terminal differentiation of skeletal myoblasts. To conclude, our results suggest that activation of MET signaling may cause defects in myogenic differentiation leading to rhabdomyosarcoma development and progression

Results Disorders manifesting various symptoms arising as a consequence of surgery limb occurred in more than half of all patients (60%). Secondary lymphedema after 6 months occurred in 29 women (19.2%). The limb on the operated breast tingling was observed in 32% of patients, numbness in 24% of patients, heaviness limbs in 15% of patients, limb sensation spreading in 15% of patients, ache in 30% of patients. Discomfort limb armpit and accompanied by 21% of respondents. Conclusions: 1. The frequency of combining elderly disorders on the side of the operated breast is high. 2. Disorders upper limb on the operated side breast are more common if done axillary lymph nodes dissection. 3. Disorders upper limb on the operated side breast occur more frequently if there is secondary lymphedema. Streszczenie Wstęp: Rak piersi jest nowotworem, którego częstość występowania stale zwiększa się w krajach wysokorozwiniętych a także w Polsce. Leczenie obejmuje między innymi terapię chirurgiczną, która jest podstawową metodą leczenia, ale daje powikłania. Celem pracy jest przedstawienie zaburzeń występujących obrębie kończyny po stronie operowanej piersi u kobiet leczonych chirurgicznie z powodu raka piersi Materiał i metody: W badaniu udział wzięło 151 kobiet leczonych chirurgicznie z powodu raka piersi (T1-4 N0-3 M0) w Centrum Onkologii Ziemi Lubelskiej św. Jana z Dukli w Lublinie w latach 2013-2015. Wyniki: Zaburzenia manifestujące się różnymi objawami powstałymi w konsekwencji zabiegu w obrębie kończyny wystąpiły u ponad połowy wszystkich badanych (60%). Wtórny obrzęk limfatyczny po 6 miesiącach wystąpił u 29 kobiet (19,2%). W obrębie kończyny po stronie operowanej piersi mrowienie zostało zaobserwowane u 32% pacjentek, drętwienie u 24% pacjentek, uczucie ciężkości kończyny u 15% badanych, uczucie rozpierania w kończynie u 15% badanych, ból u 30% badanych. Uczucie dyskomfortu w obrębie kończyny i dołu pachowego towarzyszyło 21% badanych. Wnioski: 1. Częstość występowania zaburzeń w obrębie kończyny po stronie operowanej piersi jest duża. 2. Zaburzeń w obrębie kończyny po stronie operowanej piersi występują częściej, jeśli wykonano limfadenektomię dołu pachowego. 3. Zaburzeń w obrębie kończyny po stronie operowanej piersi występują częściej, jeśli występuje wtórny obrzęk limfatyczny

Limitations of functioning in everyday life in women surgically treated for breast cancer

Admission: The primary method of treatment more frequently occurring breast cancer is surgery. The occurrence of secondary lymphedema and other symptoms of upper limb can reduce the efficiency of the patient causing hindering her daily life and functioning. The goal of the work It is to present a range of restrictions on daily functioning in patients surgically treated for breast cancer associated with the changes occurring in the limb on the side of the operated breast, Material and methods: The material consisted of 151 women treated surgically for breast cancer (T1-4 N0-3 M0) in the Oncology Center of the Lublin Region St. John of Dukla in Lublin in 2013-2015.
