Synthesis and organic functionalization approaches for magnetite (Fe3O4) nanoparticles
No full textSeveral new techniques are invented in recent years to attach organic, bio-organic functionalities to the nanostructures such as the nanoparticles. This approach of adding surface reactivity to the particles enables to tune the properties and reactivity of the resulting hybrid monolayer protected nanoparticles. Magnetic iron oxide nanoparticles of various sizes are reported which bears different organic or polymeric groups. In the present note we have revised the important methods of synthesis of magnetite (Fe3O4) nanoparticles and highlighted the most common strategies for the functionalization of these nanoparticles with organic compounds from very recent literature. This short note will help the students and researchers to screen and choose methods for the synthesis and functionalization of magnetite nanoparticles. © 2012 VBRI Press
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

Consular notification in bilateral treaties v. article 36 of Vienna Convention on consular relations in the light of ICJ judgement in the case Jadhav
No full textSprawa Jadhav jest piątym sporem w orzecznictwie MTS opartym na art. 36 Konwencji wiedeńskiej o stosunkach konsularnych z 1963 r. (po sprawach: Bread, La Grand, Avena i Diallo). Kulbhushan Sudhir Jadhav był indyjskim szpiegiem skazanym przez pakistański sąd wojskowy na karę śmierci. W 2017 roku Indie złożyły wniosek do MTS i wskazały, że Pakistan naruszył art. 36 Konwencji wiedeńskiej, nie wypełniając swojego zobowiązania wobec indyjskich urzędników konsularnych i zatrzymanego obywatela Indii, Jadhava. W sprawie tej pojawiła się jednak istotna kwestia dotycząca relacji między Konwencją wiedeńską a zasadami traktatów dwustronnych uregulowanymi w art. 73 Konwencji wiedeńskiej. Sytuacja prawna zatrzymanego i konstrukcja notyfikacji konsularnej w sprawie Jadhav była w tym przypadku odmienna od sytuacji w innych sprawach rozpatrywanych przez MTS dotyczących dostępu do konsula, w których nie było umów dwustronnych między państwami. Istnieje jednak taki traktat o dostępie do konsula podpisany w 2008 r. w Islamabadzie między Pakistanem a Indiami (UNTS nr 54471). W umowie tej strony przewidziały m.in. natychmiastowe zobowiązanie państwa przyjmującego do powiadomienia właściwego urzędu konsularnego o zatrzymaniu obywatela państwa wysyłającego. Prawo indywidualne w takim przypadku nie istnieje. Powstaje pytanie, czy MTS właściwie określił zasady prawa konsularnego, które powinny być zastosowane w sprawie Jadhav. Artykuł w sposób krytyczny analizuje ten problem. Autor w artykule wskazał na szereg błędów interpretacyjnych popełnionych przez MTS w wyroku z 17 lipca 2019 r.Jadhav Case was the fifth dispute in the ICJ judicature based on Article 36 of Vienna Convention on Consular Relations 1963 (after cases: Bread, La Grand, Avena and Diallo). Kulbhushan Sudhir Jadhav was an Indian spy convicted by the Pakistani military court for death sentence. In 2017 India submitted an application to ICJ and indicated that Pakistan had breached Article 36 of Vienna Convention by failing to fulfil its obligation versus Indian consular officers and Indian detained citizen Jadhav. There was in this case however an important question concerning relation between Vienna Convention and bilateral treaties' rules as regulated in art. 73 of Vienna Convention. The legal situation of detainee and construction of consular notification in Jadhavwas different in this case from the situations in other ICJ cases concerning consular access, where there were no bilateral agreements among states. There is however such a treaty on consular access signed in 2008 in Islamabad between Pakistan and India (UNTS No 54471). In this agreement parties provided i.a. an immediately obligation of receiving state to notify the appropriate consular post of detention of citizen of the sending state. The individual right in such case does not exist. There is a question wheatear ICJ properly identified rules of consular law, which should be applied in Jadhav Case. The paper analyses this problem in critical manner. Author in this paper pointed out several interpretative mistakes made by ICJ in Judgement from 17 July 2019
"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

Packed hybrid silica nanoparticles as sorbents with thermo-switchable surface chemistry and pore size for fast extraction of environmental pollutants
No full textThermoresponsive poly(N-isopropylacrylamide)-grafted silica nanoparticles (SiNPs) have been synthesized and fully characterized by ATR-FTIR, TGA, HRTEM, BET and DLS analysis. Hybrid solid phase extraction (SPE) beds with tuneable pore size and switchable surface chemistry were prepared by packing the polymergrafted nanoparticles inside SPE cartridges. The cartridges were tested by checking the thermoregulated elution of model compounds, namely methylene blue, caffeine and amoxicillin. Extraction of the analytes and regeneration of the interaction sites on the sorbent surface was carried out entirely in water solution by changing the external temperature below and above the lower critical solution temperature (LCST) of the polymer. The results demonstrate that the elution of model compounds depends on the temperature-regulated size of the inter-particle voids and on the change of surface properties of the PNIPAM-grafted nanoparticles from hydrophilic to hydrophobic
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
