W artykule opisano projekt automatycznego systemu podgrzewania bloku silnika, który umożliwia skrócenie czasu wtrysku paliwa zaraz po uruchomieniu silnika spalinowego. Skutkuje to zmniejszeniem zanieczyszczenia powietrza podczas fazy nagrzewania. Automatyczny system podgrzewania bloku silnika powinien być wyposażony w elektroniczną regulacją temperatury cieczy chłodzącej, która jest realizowana przez zastosowanie elektrycznej pompy cieczy.

Main goal of article was project of automatic, preheating engine block system, which enable shortening duration of fuel injection after starting combustion engine. It will cause reduction of air pollution during catalyst heating-up phase. The automatic, preheating engine block system should have electric regulation of cooling water temperature, which is realized by electric cooling water pump. Independent control of pump speed and application extra heating-up of cooling water makes possible heating cooling water when engine is turn off and control engines temperature during engine running (admission of increase temperature to 110°C). Within the framework of this work, there have been done calculations, measurements and researches whose aim was to determine the real parameters of cooling system structure for researched engine Fiat Palio Weekend 1,2 8V. Temperature measurements have been done with the help of camera ThermaCam T400 Flir and thermocouples PT 100 whereas flow rate measurements have been done with the help of turbine flow-meter Vision 2008 4F 22 with Hall's converter. Measurements was repeated several times to get reliable results. The carried out measurements allowed us to create thermal maps and flow rate characteristics of researched engines.

Obok schorzeń układu krążenia, najczęstszą przyczyną zgonów są choroby nowotworowe. Terapia fotodynamiczna PDT oparta na wykorzystaniu światłoczułych związków chemicznych wydaje się być bardzo obiecująca. Światło jest wykorzystywane w lecznictwie od tysięcy lat. W starożytności leczono przy jego pomocy choroby takie jak bielactwo, łuszczyca, krzywica, a nawet psychozy. Metoda terapii fotodynamicznej (PDT) określana często fotochemioterapią, może być skutecznym sposobem w zwalczaniu niektórych odmian nowotworów. Terapia (PDT) i diagnostyka (PDD) fotodynamiczna jako metody leczenia i wczesnego wykrywania nowotworów cieszą się niesłabnącym zainteresowaniem wielu jednostek badawczych na całym świecie. Terapia fotodynamiczna najszerzej stosowana jest w dermatologii. Przy jej pomocy leczy się wiele typów nowotworów skóry, ale prowadzone są badania nad zastosowaniem metody w zwalczaniu nowotworów mózgu, układu pokarmowego, oddechowego lub rozrodczego i wielu innych. Głównym nurtem badań jest zastosowanie metody PDT w leczeniu nowotworów, jednak może być ona również pomyślnie stosowana w lecznictwie nieonkologicznym. Przypuszcza się, że w przyszłości terapia fotodynamiczna znajdzie zastosowanie w leczeniu chorób naczyń krwionośnych, schorzeń oczu, jak również nienowotworowych chorób skóry.

Apart the cardiovascular diseases, the most cases of decease are due to cancer. Photodynamic therapy PDT, based on the use of the photosensitive compounds, seems very promising. Light is used in medicine since thousands of years. In antiquity it was used to treat such diseases as vitiligo, psoriasis, rickets (rachitis), and even psychosis. The method of photodynamic therapy (PDT), often designed as photochemotherapy, could be an effective way in combating with some varieties of tumors. Therapy (PDT) and diagnosis (PDD) photodynamic as a method of therapy and early detection of tumors has received unflagging interest of many research units from around the world. Photodynamic therapy is widely used in dermatology. With its help are cured many types of skin neoplasms, but actually are led studies on using this method in the struggle against brain tumors, gastrointestinal tumors, respiratory system tumors or genital system tumors and many others. Mainstream researches are consecrated to applying of the method of PDT in the treatment of tumors, but it also can be successfully applied in non-oncological medicine. It is also supposed that in the future the photodynamic therapy can be applied in the treatment of vascular diseases, eye diseases, as well as non-cancerous skin (cutaneous) diseases.

On the gelation of profens as a property causing their oscillatory transenantiomerization

We have previously revealed, for the first time, the tendency of some profens (S-(+)-ibuprofen, S-(+)-naproxen, and S,R-(š)-2-phenylpropionic acid) to undergo oscillatory transenantiomerization when dissolved in some low-molecular-weight solvents. Such oscillatory reactions, which are relatively rare among chemical reactions, can be stimulated by several different physical and chemical conditions. It was the objective of this study to reveal the reason for the oscillatory transenantiomerization of profens. The analytical techniques used in our study embraced measurement of the viscosity of the profen solutions and acquiring their HPLC chromatograms and 1H NMR spectra. It has been firmly established that the physical property leading to oscillatory transenantiomerization of the profens is their ability to act as low-molecular-weight gelators, which results in substantial differences between the viscosity of their solutions and that of the pure solvents. One well-known cause of oscillatory reactions is diffusion-driven instability which appears in the form of oscillations. This occurs when, because of high solution viscosity, the rate of diffusion of an intermediate reaction product becomes less its rate of formation. For the profens investigated it seems most likely that their ability to substantially increase the viscosity of the solution results in the rate of diffusion of an intermediate keto–enol product being lower than its rate of formation from the respective profen enantiomer.

Of the two possible racemates formed on the dimerization of [2.2]paracyclophane, the title compound C32H30 is the meso (RS/SR) isomer. It crystallizes in moniclinic system in space group P2-1/n with Z=4 and unit cell dimensions: a=13.7612(12), b= 11.2530(10), c=14.6974(12) A, beta=99.668(8)degree (at-100degree C). The conformation is described by interplanar angle between the linked rings, 48.67(8)degree. Some widened angles in the region of C4-C4' may indicate steric congestion.
