Phytoplasmas, causal agent of grapevine yellows diseases in the Republic of Macedonia
Full text linkSurveys and investigations of grapevine diseases, checking the presence/absence of phytoplasmas - causal agent of grapevine yellows in different variety of grapevine, were made for the first time during the period of 2006 and 2007, in the bigger vineyards in Macedonia. 7 localites and 13 regions under grapevine were analysed in this study.
Phytoplasmas are cell wall-less plant pathogenic prokaryotes, causing more than 700 diseases in different plant species.
The following pathological changes have been recorded on diseased vines: yellowing-or-reddening of leaves, wilting and triangle-shaped leaves rolling, drying of flowers and clusters, withering and bitter taste of berries, unlignificated and rubbery canes and their freezing during winter, as well as decline and death of vines in case of very sensitive variety. The consequences of the mentioned symptoms are yield loss and not proper quality of wine.
The vines infected by phytoplasmas remain permanently diseases.
Mass and severe decline of vines infected by phytoplasmas was recorded in vineyards with chardonnay cv. and vranec, which showed to be very sensitive to the studied pathogens. Somewhat, less susceptibility to GY have shown by riesling italian and rhein riesling.
Molecular detection and identification of phytoplasmas were done using polymerase chain reaction (PCR), nested PCR following by restriction fragment length polymorphism (RFLP). The results have shown the presence of Bois noir phytoplasma in all investigated region in Macedonia.
We made tipisation and confirm the presence of Bois noir (stolbur), type VKII
Phloem Limited Pathogens on Grapevine in the Republic of Macedonia
Full text linkPhytoplasmic changes as well as virus diseases in one of the most promising
crops in the Republic of Macedonia, the grapevine, are among the least studied and
researched pathogenic changes in the country. In contrast, in other European countries,
these changes have been investigated very intensively with results in publications
relevant to the sciences and practice.
During the period dedicated to the research in this PhD thesis (2008-2013), the
situation was constantly monitored from the aspect of symptomatology. The collected
material was analyzed in the Laboratory of plant and environment protection, and
typification of the present pathogens was carried out by using modern molecular methods
of PCR / RFLP, by studying seven phytoplasmic gene loci: 16S rRNA, tuf, vmp1 gene
(stol - 1H0), stamp gene, trxA-truB gene, rplS - csdB gene, cbiQ - glyA gene for the
detection of the type of the present phytoplasmas.
By applying serological ELISA technique and RT-PCR molecular diagnostics, we
determining the presence of most distributed phloemic viruses in grapevine - Grapevine
leafroll associated virus GLRaV (-1, -2, -3, -7).
In addition to grapevine as a cultivated plant and a very important crop in the
country, we also monitored the surrounding vegetation in the vineyards from which
symptomatic material was collected for analysis in order to determine the transition of
phytoplasmas from the weed vegetation to the grapevine.
The study covered a total of 766 isolates of grapevine phytoplasmas, 40 isolates
of phytoplasmas from the surrounding vegetation and 382 isolates of grapevine viruses.
During the investigated period, the presence of stolbur phytoplasmas in the grapevine and the weed vegetation was established (Bois noir, 16SrXII - A subgroup - stolbur) -
Type I and II (type a & type b) (VKI & VKII).
In relation to grapevine viruses, we monitored the presence of the leafroll virus
in grapevine (Grapevine leafroll associated virus) with groups -1 and -3 of this virus
(GLRaV-1, GLRaV-3).
Key words: phytoplasmas, Mollicutes, Grapevine leafroll associated virus,PCR/RFLP, ELIS

Фокусот беше на унапредување на практичната обука преку дуалниот модел на образование, како и размена на искуства и идеи за градење на генерации подготвени за современите предизвици
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
First report of health condition of potato samples from border crossings in the Republic of North Macedonia
Full text linkSurveys relate to performing health examinations from import, as well as taking samples at the border crossings (entry place), in the Republic of Macedonia for the period 2014 - 2017, in seed and mercantile potatoes, were examine. Phytopathogenic bacteria, fungi, viruses, nematodes, and various types of insects can cause potato diseases. In order to ensure good protection measurement from all harmful organisms, a good knowledge of the conditions of occurrence of harmful organisms, their biology, the manner of their transmission, knowledge of the conditions of the occurrence of the infection and its development, as well as the symptoms and the damages caused in plants. The tests are in accordance with the monitoring program for seeds and mercantile potatoes, and they refer to prove the presence or absence of the following harmful organisms:
- bacterial wilt and brown rot of potato – Ralstonia solanacearum
- potato crab – Synchitrium endobioticum perc.
- ring rot of potatoes – Clavibacter michiganensis subsp. sepedonicum
- cystolic nematodes of Globodera pallida (Stone) Behrens and Globodera rostochiensis (Wollenweber) Behrens in potatoe
