Elżbieta M. Walerian, Ph.D., D.Sc., a retired employee of the Institute of Fundamental Technological Research of the Polish Academy of Sciences (IPPT PAN), passed away after a serious illness, on the 26th December 2013. She was one of the scientific leaders in the Section of Environmental Acoustics of IPPT PAN and her career, educational and organizational activities were inseparably linked with the acoustics. Elżbieta Walerian was born on August 9th 1950 in Poznań. She graduated from the Faculty of Mathematics, Physics and Chemistry of the Adam Mickiewicz University in Poznań, receiving her Master of Science degree in the environmental acoustics in 1973. Five years later, under the supervision of Professor Ignacy Malecki, she obtained her PhD title, in the physical acoustics, in IPPT PAN in Warsaw. In 1979 she began working at the Section of Environmental Acoustics of IPPT PAN, where she dealt with the diffraction of acoustic waves and a description of the sound field produced by vehicles moving in an urban area.
Dental abfraction is a pathological process which causes a loss of dental hard substance. Etiopathogenesis is related to occlusal stress that causes microfractures in enamel and dentin in the cervical region. The restoration treatment is made using aesthetic adhesive materials, but must take into account the causal factors and the specific area where the restoration is done
Experiments were conducted on the response of Plectranthus forsteri ‘Nico’ to NaCl. Plants were grown in pots of 1.5 dm3 and 0.15 dm3 water solution of NaCl at concentrations 0, 5, 10, 15, 20 g dm−3 in 2011 and 0, 10, 20, 30, 40 g dm−3 in 2012 were applied one time in the beginning of experiment. Sodium chloride applied at 10-40 g NaCl·dm−3 water, reduced plant growth and values of SPAD readings. It may be stated that Plectranthus forsteri ‘Nico’ plants are tolerant to medium concentrations of sodium chloride (5-20 g NaCl·dm−3 water) and therefore can be planted in flowerbeds in urbanized areas
Thin cell layers (TCLs), which contain a small number of cells or tissues, are explants excised from different organs (stems, leaves, roots, inflorescences, flowers, cotyledons, hypocotyls/epicotyls, and embryos). After almost 45 years of research, this culture system has been used for several monocotyledonous and dicotyledonous plants of commercial importance, and for model plants. The limited amount of cells in a TCL is of paramount importance because marker molecules/genes of differentiation can be easily localized in situ in the target/responsive cells. Thus, the use of TCLs has allowed, and continues to allow, for the expansion of knowledge in plant research in a practical and applied manner into the fields of tissue culture and micropropagation, cell and organ genetics, molecular biology, biochemistry, and development. Starting from a brief historical background, the actual and potential uses of the TCL system are briefly reviewed
The aim was to assess the relationships between willingness to eat cereal products fortified with fibre, attitudes towards food technologies and some food choice motives
The rising cost of fuel, the more and more severe international standards and a growing awareness of the environmental impact of pollutant emissions have led energy efficiency to become a theme of great interest in the marine sector. The strategy for increasing energy efficiency may refer both to the consumption reduction and to the increase of energy recovery systems. This need turns out in monitoring and control strategies for energy processes on board. Monitoring information is recorded and stocked in a database, that needs to be analyzed to find out patterns in large data sets. A huge amount of data, from a RO-PAX ship, has been analyzed in order to gain a further insight into ship performances. Improvements in ship energy performances could be reached with an intense study of the historical data of the vessel attitude
The paper presents a brief review of twenty proposals for tourism regionalization of either a part of or the whole of Poland (or attempts to delimit the most attractive areas in terms of leisure), formulated between 1938 and 2012. It also analyses selected definitions of tourism regions and discusses the indicators which are proposed for the delimitation of tourism regions. Moreover, the paper attempts to indicate areas with the highest levels of tourism, in part modelled on Maria Mileska (1908-1988). It includes academic (precise) criteria for the designation of tourism regions. Some researchers’ comment that Mileska’s work is (partially) outmoded not so much from the methods employed as in the number of tourism regions and the areas covered. This should be regarded as understandable given that this regionalization was formulated at the beginning of the 1960s. Another important issue raised is the most recent tourism regionalization of Poland as prepared by Durydiwka
Every science in fact has its own paradigm, even in a science also can be developedsome approaches and methods. The method that used and developed in a creation as much aspossible should be in according the object to be studied. In addition the science actuallydinamic, constantly evolving, follow the civillization and the advancement of science world.In academic realm, especially in the field of artistic creation, a person scientificallyresponsible for the work he/she created. The same thing also applied for usage anddevelopment of a model and research method that will be applied to a case of art creations. Asfar the process could be scientifically explained; systematics in a report in form of thesis ordissertation.In art cretions, works that created won’t have any value when there is no narrativebehind the work. This narration can be story behind that creation, note, data, the experimentresults, exploration that processed into supporting part of the creation of a masterpiece. Keywords: creation method, Ilmiah, Practice based research, artist, work of art, audience,science production. Setiap ilmu pengetahuan pada hakikatnya memiliki paradigmanya masing-masing,bahkan dalam suatu ilmu dapat pula dikembangkan beberapa pendekatan dan metode.Metode yang digunakan dan dikembangkan dalam suatu penciptaan sebisa mungkin harussesuai dengan objek yang akan diteliti. Selain itu ilmu pengetahuan sebenarnya bersifatdinamis, senantiasa berkembang, mengikuti peradaban dan kemajuan dunia pengetahuan.Dalam ranah akademis, khususnya dalam bidang penciptaan seni, seseorang memilikitanggang jawab secara ilmiah atas karya yang diciptakannya. Hal yang sama berlaku bagipenggunaan dan pengembangkan suatu model dan metode penelitian yang akan diterapkanpada sebuah kasus penciptaan sebuah karya seni. Sejauh proses tersebut dapat dijelaskansecara ilmiah, sistematis dalam sebuah laporan berbentuk tesis maupun disertasi.Dalam penciptaan seni, karya yang diciptakan tidak akan memiliki nilai (value) ketikatidak ada narasi di balik karya tersebut. Narasi ini dapat berupa cerita dibalik karya tersebut,catatan, data-data, hasil eksperimen, eksplorasi yang diolah menjadi bagian pendukung dariterciptanya sebuah karya.
