Sensors-on-Paper: Fabrication of Graphite Thermal Sensor Arrays on Cellulose Paper for Large Area Temperature Mapping
No full textThis paper reports on a fabrication method to obtain multiple thermal sensors by employing an array of graphite thermocouple patterns on commonly available Xerox paper. The graphite thermocouples are patterned using two different grade graphite pencils, which show a stable and reproducible thermal sensitivity. The fabricated paper devices with multiple thermocouple arrays are capable of producing temperature mapping of the desired area. Different thermal conditions were applied to test and confirm the working of these devices. The present study shows that simple graphite trace patterns can convert a piece of paper into a thermal mapping device

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Muutused mulla mikroobide hüdrolüütilises aktiivsuses ja orgaanilise süsiniku sisalduses punase ristiku allakülviga odra kasvatamisel
No full textUurimistulemustest selgus, et punase ristiku allakülviga odra kasvatamine avaldas soodsat mõju mulla mikroorganismidele, suurendades mullaorganismide hüdrolüütilist aktiivsust. Mulla mikroobide hüdrolüütilise aktiivsuse (FDA) määramistulemused olid pärast punase ristiku allakülviga odra kasvatamist tavaviljeluse aladel 18,6% ja mahealadel 37,2% võrra suuremad võrreldes eelvilja (kartuli) alt vabanenud ala mullaga. Katseaastate keskmisena tõusis orgaanilise süsiniku (Corg %) sisaldus maheviljelusviisides 11,6% võrreldes tavaviljelusega. Pärast allakülviga odra kasvatamist võrreldes selle eelsega Corg sisalduses olulisi usaldusväärseid muutusi ei täheldatud. Enne allakülviga odra kasvatamist seos FDA ja Corg vahel sisuliselt puudus. Küll aga esines tugev korrelatiivne seos (r=0,55**) ristiku allakülviga odra järgse mulla orgaanilise süsiniku sisalduse ja mikroobse aktiivsuse vahel. Mulla huumusvaru muutused allakülviga odra kasvatamisel näitasid tavaviljelussüsteemides võrreldes kartulijärgse alaga enamasti kasvutendentsi, samas kui maheviljelusega aladel võis täheldada huumusvaru mõningast vähenemist
Mulla Sadra and the mind-body problem: A critical assessment of Sadra’s approach to the dichotomy of soul and spirit
No full textAbstract
The presence of some ambiguity about the two terms of soul and spirit, which up until now has not been considered, has been investigated in this research. This ambiguity has created problems in different fields of study such as philosophy, psychology and commentaries of religious texts. This is because the two words are usually used synonymously.
The main aim of this research is to investigate whether the human being has an independent spirit in addition to the body and the soul or not. In other words it is attempting to establish if man is a tripartite existence made of body, soul and spirit.
In order to attain this aim the ideas of various philosophers are discussed on different subjects regarding the soul with particular attention to the philosophical system introduced in the seventeenth century AD by the Muslim philosopher, Sadr al-din Shirazi. This consisted of two other philosophical systems in Islamic philosophy, peripatetic (mashā‟) and illuminative („ishrāq) combined with mystical and religious teachings. His idea about the soul was set as the basis for the arguments regarding the soul and the ideas of other philosophers were compared to it.
This research explores the principles that form Sadra‟s beliefs about the soul. One of Sadra‟s principles, the fundamentality of existence, is explained. This principle aims to prove the reality of the external world and the soul as one of these realities. The topics of motion and time and the views of philosophers about these are cited. In addition, another Sadra‟s important principles, trans-substantial motion, is mentioned and explained and it is suggested that the difference between Sadra‟s and other philosophers‟ ideas about the soul lies in accepting or rejecting motion in substance. According to Sadra, the soul which is material at the beginning of its creation moves towards immateriality by trans-substantial motion.
Then philosophers‟ ideas about the soul are mentioned as well as their disagreements regarding different issues such as immateriality, motion, origination of the soul etc. In addition, the problem that Sadra‟s philosophical system faces in regard to the soul is discussed in particular since it is the main aim of this research.
It is concluded that Sadra‟s idea is more complete than the other ideas regarding the soul. The existence of the soul found a better justification in this idea. The problem of dualism of the soul and body with which other philosophers were faced has been resolved. Meanwhile the problem of this philosophical idea which sees the soul to be the same as the spirit was investigated and it was stated that this problem has caused many diversities of opinion between philosophers in subjects related to the soul. The propounded solution for all the cases was to accept the dichotomy of the soul and spirit. Religious texts have been classified, analysed and used to support this idea and by using different evidences it was confirmed that the soul and the spirit are two independent substances and that the human being is a tripartite existence
Bait Units for Collection of House Flies
No full textLurtox™4 is a proteinaceous attractant for Musca domestica L. and other synanthropic Diptera (Mulla et al. 1973: Willson and Mulla 1973a) and is easily mixed with commercial poison sugar baits. The mixture of Lurtox and dichlorvos sugar bait (50:50 by wt) can be administered in measurable quantities into compact bait units where dead flies can be easily recovered for counting and for other studies. While developing Lurtox for control of Hippelates eye gnats, Mulla et al. (1973) found that moisture was essential for the emanation of the volatile attractants contained in the bait. Therefore, if the prevalent humidity level is not sufficient to activate the attractant, the bait unit designed for use with the bait mixture should include a moisture sourc
"Closing the R&D Gap, Evaluating the Sources of R&D Spending"
No full textBoth spending and tax policies have been implemented in the United States with the goal of stimulating private sector research and development (R&D). Karier questions whether current R&D policy, especially the research and experimentation tax credit, can contribute to closing the gap between nondefense expenditures on R&D in the United States and such expenditures in other countries, such as Japan and Germany. He also explores possible changes to our current R&D policy to make it more effective.
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
