Seamless and COLLAborative mobile learning on tablet computers”). The main research method applied during the development of the SCOLLAm mobile learning system is design-based research. It assumes iterative refinement of the system guided by collaboration between researches and practitioners. Following the identification of requirements, a multiplatform mobile learning system <em>SCOLLAm [in]Form </em>was developed. Several experiments were designed and conducted in the first and second grade of elementary school. <em>SCOLLAm [in]Form system </em>was used to design learning activities for math classes during which students practice calculation. System refinements were based on experience and interaction data gathered during class observations. In addition to implemented improvements, the data were used to outline possible improvements and deficiencies of the system that should be addressed in the next phase of the <em>SCOLLAm [in]Form</em> development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adaptation" title="adaptation">adaptation</a>, <a href="https://publications.waset.org/abstracts/search?q=collaborative%20learning" title=" collaborative learning"> collaborative learning</a>, <a href="https://publications.waset.org/abstracts/search?q=educational%20technology" title=" educational technology"> educational technology</a>, <a href="https://publications.waset.org/abstracts/search?q=mobile%20learning" title=" mobile learning"> mobile learning</a>, <a href="https://publications.waset.org/abstracts/search?q=tablet%20computers" title=" tablet computers"> tablet computers</a> </p> <a href="https://publications.waset.org/abstracts/64887/a-design-based-approach-to-developing-a-mobile-learning-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/64887.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">272</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Immunoglobulin G Glycosylation Profile in Influenza and COVID-19 Infected Patients</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marina%20Kljakovi%C4%87-Ga%C5%A1pi%C4%87%20Batinjan">Marina Kljaković-Gašpić Batinjan</a>, <a href="https://publications.waset.org/abstracts/search?q=Tea%20Petrovi%C4%87"> Tea Petrović</a>, <a href="https://publications.waset.org/abstracts/search?q=Frano%20Vu%C4%8Dkovi%C4%87"> Frano Vučković</a>, <a href="https://publications.waset.org/abstracts/search?q=Irzal%20Had%C5%BEibegovi%C4%87"> Irzal Hadžibegović</a>, <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Radovani"> Barbara Radovani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Jurin"> Ivana Jurin</a>, <a href="https://publications.waset.org/abstracts/search?q=Lovorka%20%C4%90erek"> Lovorka Đerek</a>, <a href="https://publications.waset.org/abstracts/search?q=Eva%20Huljev"> Eva Huljev</a>, <a href="https://publications.waset.org/abstracts/search?q=Alemka%20Markoti%C4%87"> Alemka Markotić</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivica%20Luk%C5%A1i%C4%87"> Ivica Lukšić</a>, <a href="https://publications.waset.org/abstracts/search?q=Irena%20Trbojevi%C4%87-Akma%C4%8Di%C4%87"> Irena Trbojević-Akmačić</a>, <a href="https://publications.waset.org/abstracts/search?q=Gordan%20Lauc"> Gordan Lauc</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Gudelj"> Ivan Gudelj</a>, <a href="https://publications.waset.org/abstracts/search?q=Rok%20%C4%8Civljak"> Rok Čivljak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Immunoglobulin G has essential role in defense against infectious diseases, but its role cannot be fully recognized without understanding of changes in its N-glycans attached to the Fc domain.

Matching pursuit is used for atomic decomposition, and is shown to achieve optimal speech detection capability at high data compression rates for low signal to noise ratios. The most active dictionary elements found by matching pursuit are used for the signal reconstruction so that the algorithm adapts to the individual speakers dominant time-frequency characteristics. Speech has a high peak to average ratio enabling matching pursuit greedy heuristic of highest inner products to isolate high energy speech components in high noise environments. Gabor and gammatone atoms are both investigated with identical logarithmically spaced center frequencies, and similar bandwidths. The algorithm performs equally well for both Gabor and gammatone atoms with no significant statistical differences. The algorithm achieves 70% accuracy at a 0 dB SNR, 90% accuracy at a 5 dB SNR and 98% accuracy at a 20dB SNR using 30dB SNR as a reference for voice activity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomic%20decomposition" title="atomic decomposition">atomic decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=gabor" title=" gabor"> gabor</a>, <a href="https://publications.waset.org/abstracts/search?q=gammatone" title=" gammatone"> gammatone</a>, <a href="https://publications.waset.org/abstracts/search?q=matching%20pursuit" title=" matching pursuit"> matching pursuit</a>, <a href="https://publications.waset.org/abstracts/search?q=voice%20activity%20detection" title=" voice activity detection"> voice activity detection</a> </p> <a href="https://publications.waset.org/abstracts/27613/a-simple-adaptive-atomic-decomposition-voice-activity-detector-implemented-by-matching-pursuit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27613.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">290</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> Comparison of Computer Software for Swept Path Analysis on Example of Special Paved Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ivana%20Cestar">Ivana Cestar</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivica%20Stan%C4%8Deri%C4%87"> Ivica Stančerić</a>, <a href="https://publications.waset.org/abstracts/search?q=Sa%C5%A1a%20Ahac"> Saša Ahac</a>, <a href="https://publications.waset.org/abstracts/search?q=Vesna%20Drag%C4%8Devi%C4%87"> Vesna Dragčević</a>, <a href="https://publications.waset.org/abstracts/search?q=Tamara%20D%C5%BEambas"> Tamara Džambas</a> </p> <p class="card-text"><strong>Abstract:</strong></p> On special paved areas, such as road intersections, vehicles are usually moving through horizontal curves with smaller radii and occupy considerably greater area compared to open road segments. Planning procedure of these areas is mainly an iterative process that consists of designing project elements, assembling those elements to a design project, and analyzing swept paths for the design vehicle. If applied elements do not fulfill the swept path requirements for the design vehicle, the process must be carried out again. Application of specialized computer software for swept path analysis significantly facilitates planning procedure of special paved areas. There are various software of this kind available on the global market, and each of them has different specifications. In this paper, comparison of two software commonly used in Croatia (Auto TURN and Vehicle Tracking) is presented, their advantages and disadvantages are described, and their applicability on a particular paved area is discussed. In order to reveal which one of the analyszed software is more favorable in terms of swept paths widths, which one includes input parameters that are more relevant for this kind of analysis, and which one is more suitable for the application on a certain special paved area, the analysis shown in this paper was conducted on a number of different intersection types. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=software%20comparison" title="software comparison">software comparison</a>, <a href="https://publications.waset.org/abstracts/search?q=special%20paved%20areas" title=" special paved areas"> special paved areas</a>, <a href="https://publications.waset.org/abstracts/search?q=swept%20path%20analysis" title=" swept path analysis"> swept path analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=swept%20path%20input%20parameters" title=" swept path input parameters"> swept path input parameters</a> </p> <a href="https://publications.waset.org/abstracts/34359/comparison-of-computer-software-for-swept-path-analysis-on-example-of-special-paved-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34359.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> The School-to-Work Transition: The Case of NEET Youths from Rural Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=An%C4%91elka%20Stojanovi%C4%87">Anđelka Stojanović</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Mihajlovi%C4%87"> Ivan Mihajlović</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivica%20Nikoli%C4%87"> Ivica Nikolić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the past years, due to the financial crisis and the tightening of conditions on the labor market, young people are facing great challenges in achieving financial independence and finding their place in society. Higher unemployment rates, poorer living conditions, separation from the labor market, and longer school-to-work transitions particularly affect rural youth and make significant differences between youth groups in rural and urban areas. Improving employability skills and development of instruments for further learning among young people “Not in Education, Employment, or Training” (NEET) should not be only the concerns of these people, already adequately be directed and supported by the institutions. According to the World Bank data, the share of youth not in education, employment or training (NEET), in the European Union in the past few years decreases but still shows a significant share in the total percentage of the youth population. In 2017 rate was 10.96% while in 2018 that value was 10.38%. When observing individual countries in Europe, especially those with lower incomes, this rate is much higher. It was concluded that this topic was not sufficiently elaborated and presented in the social and scientific environment. Therefore, the aim of this paper is to identify and systematize the problems of school-to-work transition among young NEETs living in rural areas as well as the initiatives for addressing their problems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NEET%20youth" title="NEET youth">NEET youth</a>, <a href="https://publications.waset.org/abstracts/search?q=risks%20and%20initiatives" title=" risks and initiatives"> risks and initiatives</a>, <a href="https://publications.waset.org/abstracts/search?q=rural%20youth" title=" rural youth"> rural youth</a>, <a href="https://publications.waset.org/abstracts/search?q=school-to-work%20transition" title=" school-to-work transition"> school-to-work transition</a> </p> <a href="https://publications.waset.org/abstracts/128090/the-school-to-work-transition-the-case-of-neet-youths-from-rural-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128090.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">114</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4</span> High School Stem Curriculum and Example of Laboratory Work That Shows How Microcomputers Can Help in Understanding of Physical Concepts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jelena%20Slugan">Jelena Slugan</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivica%20Ru%C5%BEi%C4%87"> Ivica Ružić</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We are witnessing the rapid development of technologies that change the world around us. However, curriculums and teaching processes are often slow to adapt to the change; it takes time, money and expertise to implement technology in the classroom. Therefore, the University of Split, Croatia, partnered with local school Marko Marulić High School and created the project "Modern competence in modern high schools" as part of which five different curriculums for STEM areas were developed. One of the curriculums involves combining information technology with physics. The main idea was to teach students how to use different circuits and microcomputers to explore nature and physical phenomena. As a result, using electrical circuits, students are able to recreate in the classroom the phenomena that they observe every day in their environment. So far, high school students had very little opportunity to perform experiments independently, and especially, those physics experiment did not involve ICT. Therefore, this project has a great importance, because the students will finally get a chance to develop themselves in accordance to modern technologies. This paper presents some new methods of teaching physics that will help students to develop experimental skills through the study of deterministic nature of physical laws. Students will learn how to formulate hypotheses, model physical problems using the electronic circuits and evaluate their results. While doing that, they will also acquire useful problem solving skills. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ICT%20in%20physics" title="ICT in physics">ICT in physics</a>, <a href="https://publications.waset.org/abstracts/search?q=curriculum" title=" curriculum"> curriculum</a>, <a href="https://publications.waset.org/abstracts/search?q=laboratory%20activities" title=" laboratory activities"> laboratory activities</a>, <a href="https://publications.waset.org/abstracts/search?q=STEM%20%28science" title=" STEM (science"> STEM (science</a>, <a href="https://publications.waset.org/abstracts/search?q=technology" title=" technology"> technology</a>, <a href="https://publications.waset.org/abstracts/search?q=engineering" title=" engineering"> engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematics%29" title=" mathematics)"> mathematics)</a> </p> <a href="https://publications.waset.org/abstracts/72981/high-school-stem-curriculum-and-example-of-laboratory-work-that-shows-how-microcomputers-can-help-in-understanding-of-physical-concepts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72981.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">201</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Geospatial Analysis of Hydrological Response to Forest Fires in Small Mediterranean Catchments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bojana%20Horvat">Bojana Horvat</a>, <a href="https://publications.waset.org/abstracts/search?q=Barbara%20Karleusa"> Barbara Karleusa</a>, <a href="https://publications.waset.org/abstracts/search?q=Goran%20Volf"> Goran Volf</a>, <a href="https://publications.waset.org/abstracts/search?q=Nevenka%20Ozanic"> Nevenka Ozanic</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivica%20Kisic"> Ivica Kisic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Forest fire is a major threat in many regions in Croatia, especially in coastal areas. Although they are often caused by natural processes, the most common cause is the human factor, intentional or unintentional. Forest fires drastically transform landscapes and influence natural processes. The main goal of the presented research is to analyse and quantify the impact of the forest fire on hydrological processes and propose the model that best describes changes in hydrological patterns in the analysed catchments. Keeping in mind the spatial component of the processes, geospatial analysis is performed to gain better insight into the spatial variability of the hydrological response to disastrous events. In that respect, two catchments that experienced severe forest fire were delineated, and various hydrological and meteorological data were collected both attribute and spatial. The major drawback is certainly the lack of hydrological data, common in small torrential karstic streams; hence modelling results should be validated with the data collected in the catchment that has similar characteristics and established hydrological monitoring. The event chosen for the modelling is the forest fire that occurred in July 2019 and burned nearly 10% of the analysed area. Surface (land use/land cover) conditions before and after the event were derived from the two Sentinel-2 images. The mapping of the burnt area is based on a comparison of the Normalized Burn Index (NBR) computed from both images. To estimate and compare hydrological behaviour before and after the event, curve number (CN) values are assigned to the land use/land cover classes derived from the satellite images. Hydrological modelling resulted in surface runoff generation and hence prediction of hydrological responses in the catchments to a forest fire event. The research was supported by the Croatian Science Foundation through the project 'Influence of Open Fires on Water and Soil Quality' (IP-2018-01-1645). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Croatia" title="Croatia">Croatia</a>, <a href="https://publications.waset.org/abstracts/search?q=forest%20fire" title=" forest fire"> forest fire</a>, <a href="https://publications.waset.org/abstracts/search?q=geospatial%20analysis" title=" geospatial analysis"> geospatial analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrological%20response" title=" hydrological response"> hydrological response</a> </p> <a href="https://publications.waset.org/abstracts/113971/geospatial-analysis-of-hydrological-response-to-forest-fires-in-small-mediterranean-catchments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/113971.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">136</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Speaker Identification by Atomic Decomposition of Learned Features Using Computational Auditory Scene Analysis Principals in Noisy Environments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thomas%20Bryan">Thomas Bryan</a>, <a href="https://publications.waset.org/abstracts/search?q=Veton%20Kepuska"> Veton Kepuska</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivica%20Kostanic"> Ivica Kostanic</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Speaker recognition is performed in high Additive White Gaussian Noise (AWGN) environments using principals of Computational Auditory Scene Analysis (CASA). CASA methods often classify sounds from images in the time-frequency (T-F) plane using spectrograms or cochleargrams as the image. In this paper atomic decomposition implemented by matching pursuit performs a transform from time series speech signals to the T-F plane. The atomic decomposition creates a sparsely populated T-F vector in “weight space” where each populated T-F position contains an amplitude weight. The weight space vector along with the atomic dictionary represents a denoised, compressed version of the original signal. The arraignment or of the atomic indices in the T-F vector are used for classification. Unsupervised feature learning implemented by a sparse autoencoder learns a single dictionary of basis features from a collection of envelope samples from all speakers. The approach is demonstrated using pairs of speakers from the TIMIT data set. Pairs of speakers are selected randomly from a single district. Each speak has 10 sentences. Two are used for training and 8 for testing. Atomic index probabilities are created for each training sentence and also for each test sentence. Classification is performed by finding the lowest Euclidean distance between then probabilities from the training sentences and the test sentences. Training is done at a 30dB Signal-to-Noise Ratio (SNR). Testing is performed at SNR’s of 0 dB, 5 dB, 10 dB and 30dB. The algorithm has a baseline classification accuracy of ~93% averaged over 10 pairs of speakers from the TIMIT data set. The baseline accuracy is attributable to short sequences of training and test data as well as the overall simplicity of the classification algorithm. The accuracy is not affected by AWGN and produces ~93% accuracy at 0dB SNR. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=time-frequency%20plane" title="time-frequency plane">time-frequency plane</a>, <a href="https://publications.waset.org/abstracts/search?q=atomic%20decomposition" title=" atomic decomposition"> atomic decomposition</a>, <a href="https://publications.waset.org/abstracts/search?q=envelope%20sampling" title=" envelope sampling"> envelope sampling</a>, <a href="https://publications.waset.org/abstracts/search?q=Gabor%20atoms" title=" Gabor atoms"> Gabor atoms</a>, <a href="https://publications.waset.org/abstracts/search?q=matching%20pursuit" title=" matching pursuit"> matching pursuit</a>, <a href="https://publications.waset.org/abstracts/search?q=sparse%20dictionary%20learning" title=" sparse dictionary learning"> sparse dictionary learning</a>, <a href="https://publications.waset.org/abstracts/search?q=sparse%20autoencoder" title=" sparse autoencoder"> sparse autoencoder</a> </p> <a href="https://publications.waset.org/abstracts/51069/speaker-identification-by-atomic-decomposition-of-learned-features-using-computational-auditory-scene-analysis-principals-in-noisy-environments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51069.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">289</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Lacustrine Sediments of the Poljanska Locality in the Miocene Climatic Optimum North Croatian Basin, Croatia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marijan%20Kova%C4%8DI%C4%87">Marijan KovačIć</a>, <a href="https://publications.waset.org/abstracts/search?q=Davor%20Paveli%C4%87"> Davor Pavelić</a>, <a href="https://publications.waset.org/abstracts/search?q=Darko%20Tiblja%C5%A1"> Darko Tibljaš</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivo%20Gali%C4%87"> Ivo Galić</a>, <a href="https://publications.waset.org/abstracts/search?q=Frane%20Markovi%C4%87"> Frane Marković</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivica%20Pavi%C4%8DI%C4%87"> Ivica PavičIć</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The North Croatian Basin (NCB) occupies the southwestern part of the Pannonian Basin System and belongs to the Central Paratethys realm. In a quarry near the village of Poljanska, on the southern slopes of Mt. Papuk in eastern Croatia, a 40-meter-thick section is exposed, consisting of well-bedded, mixed, carbonate-siliciclastic deposits with occurrences of pyroclastics. Sedimentological investigation indicates that a salina lake developed in the central NCB during the late early Miocene. Field studies and mineralogical and petrological analyses indicate that alternations of laminated crypto- characterize the lower part of the section to microcrystalline dolomite and analcimolite (sedimentary rocks composed essentially of authigenic analcime) associated with tuffites and marls. The pyroclastic material is a product of volcanic activity at the end of the early Miocene, while the formation of analcime, the zeolite group mineral, is a result of an alteration of pyroclastic material in an alkaline lacustrine environment. These sediments were deposited in a shallow, hydrologically closed lake that was controlled by an arid climate during the first phase of its development. The middle part of the section consists of dolomites interbedded with analcimolites and sandstones. The sandstone beds are a result of the increased supply of clastic material derived from the locally uplifted metamorphic and granitoid basement. The emplacement of sandstones and dolomites reflects a distinct alternation of hydrologically open and closed lacustrine environments controlled by the frequent alternation of humid and arid climates, representing the second phase of lake development. The siliciclastics of the third phase of lake development were deposited during the Middle Miocene in a hydrologically mostly open lake. All lacustrine deposition coincides with the Miocene Climatic Optimum, which was characterized by a hot and warm climate. The sedimentological data confirm the mostly wet conditions previously identified by paleobotanical studies in the region. The exception is the relatively long interval of arid climate in the late early Miocene that controlled the first phase of lake evolution, i.e., the salina-type lake. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=early%20Miocene" title="early Miocene">early Miocene</a>, <a href="https://publications.waset.org/abstracts/search?q=Pannonian%20basin%20System" title=" Pannonian basin System"> Pannonian basin System</a>, <a href="https://publications.waset.org/abstracts/search?q=pyroclastics" title=" pyroclastics"> pyroclastics</a>, <a href="https://publications.waset.org/abstracts/search?q=salina-type%20lake" title=" salina-type lake"> salina-type lake</a> </p> <a href="https://publications.waset.org/abstracts/139118/lacustrine-sediments-of-the-poljanska-locality-in-the-miocene-climatic-optimum-north-croatian-basin-croatia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139118.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">213</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
