![]() ![]() The results, although limited by a low number of investigated humans and animals, indicate indirectly a specialization in the exploitation of local water resources. Based on the dating of the antler, unaffected by FRE, and comparative analysis, the reservoir offset for one of the graves was estimated to 740 radiocarbon years. The results indicate a significant proportion of freshwater food in the diet, which caused the radiocarbon dates to be too old due to the freshwater reservoir effect (FRE). PEARSON CHEMISTRY GEN CHEM TEXT VBOOK SERIESUnder a new pilot program in 2010–2013, a series of radiocarbon measurements was made for the human bones and an artefact of red deer antler, along with analyses of the stable isotopes ratios of carbon (δ13C) and nitrogen (δ15N) in the collagen. 14C dates made for samples of human bones until 2009 did not coincide with the expected age of the graves. They left behind a small cemetery consisting of at least six graves. In the 3rd millennium BC an island on the Łańskie Lake in north-eastern Poland was seasonally settled by a group of people practicing a syncretic burial ritual, exhibiting indigenous and foreign patterns. The positive learning experiences of the students in performing microscale experiments in Chemistry accounts for the development of the students’ learning outcomes. ![]() ![]() It was able to improve the learning competencies of the students in the cognitive, affective and psychomotor domain. The results of the study showed that the designed microscale experiments were effective in developing the learning outcomes of the students in Chemistry. The study used the pretest and posttest randomized control group design and subjected the experimental group to the microscale experiments and the control group to the traditional method of performing chemistry experiments. It was meant to describe and compare the learning outcomes of the students who were exposed and not exposed to microscale experiments and identified the learning experiences of the students exposed to the microscale experiments. The study was conducted to evaluate the effectiveness of the designed microscale experiments in developing the learning outcomes of the students along the cognitive, affective and psychomotor domains. Using a vacuum drying process to control the morphology of inkjet−printed films, line patterns of 2822 PPI resolution having a root−mean−square (RMS) roughness of 1.331 nm without voids were successfully fabricated. Therefore, to control the morphology, we carefully investigated the drying process of the inkjet−printed inks in the microchannel. Unlike the spin−coating process, the drying process of inkjet−printed films on the microchannel has a great effect on the sublimation of transferred thin film. Most sublimation transferred patterns have porous surfaces under drying conditions in an air atmosphere. Inkjet printing conditions on the donor substrate with 2822 PPI microchannels were investigated in detail according to the drop space and line space. Co−solvented ink with a 1:1 ratio of N,N−dimethylformamide (DMF) to ortho−dichlrorobenzene (oDCB) was used, and the inkjet driving waveform was optimized via analysis of Ohnesorge (Oh)-Reynolds (Re) numbers. We implemented ultra−high resolution patterns of 2822 pixels−per−inch (PPI) via an inkjet printing and vacuum drying process grafted onto a sublimation transfer process. ![]()
