Claude Longeon, les archives et les livres, entre recherche et valorisation
Authors: Mouren Raphaële
Published: June 2020

Utilisant lui-même des sources très nombreuses et très variées pour ses recherches, Claude Longeon, spécialiste de la littérature française et forézienne du XVI e  siècle, a, tout au long de sa carrière, une approche assez originale : celle de publier des inventaires, des catalogues, des bibliographies, des documents originaux pour les mettre à la disposition des chercheurs. Cet article explore et analyse ces travaux de Longeon en les replaçant dans leur époque.
De 1540 à 1543 : Étienne Dolet et l’amplification des Gestes . Essai de mise au point
Authors: Astier Sophie
Published: June 2020

Le présent article se propose de reprendre le dossier des Fata de 1539 et des Gestes de 1540 et 1543 composés et publiés par Étienne Dolet, tout en s’intéressant plus particulièrement aux additions de l’édition de 1543. Au fil du temps, le discours s’étoffe, s’enrichit, voire finit par se réorienter complètement. Il y a de 1540 à 1543 peu de modifications dans le texte déjà existant, mais les ajouts faits ensuite sont particulièrement intéressant car, contrairement à ce que l’on observe dans le reste de l’œuvre, ils reposent assez peu sur un travail de compilation. Les évolutions observées font des Gestes un ensemble complexe, qu’il faut sans doute analyser par couches successives d’écriture venant se sédimenter au fur et à mesure de l’introduction de lectures nouvelles et de l’évolution du projet historiographique de Dolet vers quelque chose de plus politique.
Claude d’Urfé (1501-1558), ambassadeur, mécène, bibliophile et gentilhomme forézien
Authors: Cooper Richard
Published: June 2020

Claude d’Urfé eut une carrière très en vue dans la décennie 1546-1558. Ambassadeur de France au Concile de Trente, puis à Rome, et ensuite gouverneur des Enfants de France, D’Urfé jouissait à la cour de la faveur des rois François I er et Henri II. Mais quelles étaient ses relations dans son Forez natal et dans le Lyonnais ? C’est à Montbrison qu’il accueillit en 1536 son souverain et toute la cour. C’est à Saint-Étienne-le-Molard qu’il fit transformer le manoir ancestral, La Bâtie d’Urfé, en élégant château renaissant, décoré par de grands artistes italiens, pour héberger sa riche bibliothèque et sa collection d’antiquités. Et c’est après son retour à la cour qu’il reçut la dédicace d’ouvrages d’auteurs foréziens ou lyonnais, tels Gabriele Simeoni, Jean Papon, Charles Fontaine, ou Pierre Girinot, qui percevaient en lui un éventuel mécène. Deux dédicaces sortent de l’ordinaire : l’imprimeur Robert Granjon le choisit pour mieux faire connaître à la cour ses nouveaux caractères de civilité  ; et l’antiquaire Guillaume Du Choul lui dédia son Discours de la Religion des Romains en témoignage de leur passion commune pour les antiquités et pour les pratiques religieuses classiques. Cette reconnaissance publique de la part de ses voisins masque le fait que ce gentilhomme forézien, une fois devenu serviteur royal et courtisan, n’eut plus le temps de jouir de son magnifique château, ni de ses livres, ni de ses marbres antiques.
Vieillir en Allemagne : possibilités de participation sociale et risques d’exclusion
Authors: Kümpers Susanne , Alisch Monika
Published: June 2020

Dans la société allemande, les possibilités de participation sociale et les risques d’exclusion des personnes âgées varient en fonction de leur catégorie sociale. Ainsi, pour les personnes âgées, la pauvreté, appréciée à l’aune du statut socio-économique, représente un obstacle important à l’autonomie. La particularité de la pauvreté des personnes âgées est qu’elle est invisible. Par ailleurs, l’âge avançant, le lien étroit existant entre le statut socio-économique, l’état de santé et l’accès à une prise en charge sanitaire, médicale et thérapeutique a des répercussions considérables sur les possibilités de réalisation personnelle des individus [2 . L’inégalité sociale verticale, mesurée sur la base de l’indice de classe sociale (revenus, niveau d’études, emploi), interagit avec d’autres caractéristiques sociales horizontales (sexe, appartenance ethnique, handicap, orientation sexuelle) d’une part, et avec les conditions de la sphère sociale d’autre part, ce qui a des conséquences sur les possibilités de participation sociale et les risques d’exclusion.

This paper formulates and analyzes a modified Previte-Hoffman food web with mixed functional responses. We investigate the existence, uniqueness, positivity and boundedness of the proposed model's solutions. The asymptotic local and global stability of the steady states are discussed. Analytical study of the proposed model reveals that it can undergo supercritical Hopf bifurcation. Furthermore, analysis of Turing instability in spatiotemporal version of the model is carried out where regions of pattern creation in parameters space are obtained. Using detailed numerical simulations for the diffusive and non-diffusive cases, the theoretical findings are verified for distinct sets of parameters.

The detection of neural spikes plays an important role in studying and processing extracellular recording signals, which promises to be able to extract the necessary spike data for all subsequent analyses. The existing algorithms for spike detection have achieved great progress but there still remains much room for improvement in terms of the robustness to noise and the flexibility in the spike shape. To address this issue, this paper presents a novel method for spike detection based on the theory of sparse representation. By analyzing the characteristics of extracellular neural recordings, a targetdriven sparse representation framework is firstly constructed, with which the neural spike signals can be effectively separated from background noise. In addition, considering the fact that the spikes emitted by different neurons have different shapes, we then learn a universal dictionary to give a sparse representation of various spike signals. Finally, the information (location and number) of spikes in the recorded signal are achieved by comprehensively analyzing the sparse features. Experimental results demonstrate that the proposed method outperforms the existing methods in the spike detection problem.
Why superquantum, no-signaling correlations cannot exist
Authors: Uzan Pierre
Published: June 2020

The idea that nonlocal correlations stronger than quantum correlations between two no-signaling systems could “theoretically” exist is based on an incorrect statistical interpretation of the no-signaling condition. This article shows that any physically realizable no-signaling
“box” involving local incompatible observables indeed requires to be described in a noncommutative, quantum-like language of operators, which leads to the derivation of the Tsirelson bound and then contradicts this idea.
Law of physics 20th-century scientists overlooked. I. The velocity differential propagation of light
Authors: Ranzan Conrad
Published: June 2020

Theorists of the 20th century had failed to recognize the law governing the prolonged interaction between electromagnetic radiation and gravity gradients—they had overlooked the principle of velocity differential propagation (the Principle). Historical background is provided
and includes the bafflement surrounding the discovery of the cosmic redshift and its interpretation. The Principle is presented. Its application to gravity wells reveals that light waves traversing the external portion of a gravity well will intrinsically lose energy. The energy loss
occurs during the inbound propagation AND during the outbound propagation. In other words, light undergoes redshifting throughout the entire journey. Three proofs are detailed. Observational evidence (several examples) is presented. Highlights are given of the momentous misinterpretation
that could have been avoided if only there had emerged cognizance of the Principle. Examined is the question, How could it have happened that scientists missed the Principle? The implications for cosmology are profound.
Decay characteristics of neutron excess iron nuclei
Authors: Bevelacqua J. J.
Published: June 2020

In neutron star mergers, neutron excess nuclei and the r-process are important factors governing the production of heavy nuclear systems. An evaluation of iron nuclei suggests that the heaviest Z = 26 nucleus will have mass 76 with filling of the 1g9/2 neutron
shell. A = 73‐76 iron isotopes have limited experimental half-life data, but the model predicts beta decay half-lives in the range of 20‐30 ms. Based on comparisons to Z = 20 and lighter Z = 26 systems, these results likely
overestimate the experimental half-lives of these A = 73‐76 neutron excess iron nuclei.

About a possible derivation of the London equations
Authors: Koutandos Spiros
Published: June 2020

In continuation of some previous work published by this author in an open access journal [S. Koutandos, IOSR J. Appl. Phys. 10, 26 (2018); 10, 35 (2018); 9, 47 (2017); 11, 72 (2019)], he now derives the London equations from an expansion of the rotation of
vorticity. Vorticity is a vector quantity described in fluid mechanics which characterizes the angular motion of a point particle as it moves. A small ball, for example, found in a field of vorticity would turn around itself. This is in accordance with the existence of the spin of a particle.
We claim that due to the dipolar nature of the electric charge, its rotation vortex effects appear. It is found that the total time derivative of the radius possibly due to Brownian motion is different from the velocity but is used as a starting point in describing a fluid-like flow for the
electron where all the quantities behave accordingly. Finally, we ascribe the relativistic radius of the electron to a curvature of spacetime from the mass energy equivalence for the electric energy. This paper may also be looked at as one more discussion about the hidden variables quest in
quantum mechanics, offering some progress in understanding them.
The influence of gravitational field on time
Authors: Yi Yan
Published: June 2020

Existing theories cannot reasonably explain some astronomical phenomena now observed. Therefore, it is necessary to consider the possible limitations of existing theories. First, eight important defects of the existing theories are analyzed in this paper. These eight important defects
prove that there are serious errors in the space-time view of the existing macro-physical theories, and it is necessary to rethink the space-time relationship. Then the philosophical basis of reference system is discussed, and a new reference system is constructed. Then, based on the new reference
system and the space-time relationship, the approximation limit of time and space at infinite distance from the source of gravitational field is reconstructed, and the relationship between gravitational field and space-time is reconstructed according to this limit. Then the relationships between
the new theory and the existing theories are discussed, and the conclusions are consistent with the limitations of the existing theories discussed above. Finally, the new theory is used to explain the above phenomena which cannot be explained by the existing theories.
Cultural Intelligence for Optimal Outcomes
Authors: Dent Michael
Published: June 2020

Four types of intelligence are relevant to any discussion relating to the future of graduate education: basic IQ (or intelligence quotient), emotional intelligence, artificial intelligence, and cultural intelligence (CQ). All of these will have an increasing impact on the roles of both university students and academics in the future. The difficulty is in assessing what changes these are likely to bring to the educational landscape. This chapter attempts to understand the drivers of change and the likely outcomes. Some small proposals are then made as to how both universities and students should plan for their future. This chapter will not assist you on learning how to play the violin.
Emotional Intelligence 4.0
Authors: Gomez Brendan J. , Ang Patricia M.
Published: June 2020

Covid-19 has created global chaos and change unprecedented in modern history. The reality of emerging from safe-houses to discover a planet with vastly different terrain – socially, economically and psychologically is no longer science-fiction. The pandemic has demonstrated the great need for IR4.0 with its technological advances that will mobilize local businesses and global economies. At the heart of both the adoption of advances and the creation of solutions in mitigating global crisis is the heart of the people – both organizational adopters of technology and everyday users. This chapter digs deep into our pain wherein human advances will require changes not only in technology, but in the very people that make up our organizations and economies. Herein, Emotional Intelligence 4.0 brings the combined power of our cognitive and emotional abilities in creating launch-pads with people solutions that hyper-drive us into future frontiers.
Negative and Positive Mind-Wandering
Authors: Travis Frederick
Published: June 2020

Mind-wandering is considered by many as a sign of an “unhappy mind” and associated with ill-health. Since the mind wanders half of the time, it is unlikely that mind-wandering plays no role in cognitive processing. Mind-wandering can be filled with negative thoughts ‑ negative mind-wandering associated with worry and rumination; or it can be filled with positive thoughts ‑ positive mind-wandering associated with imagination and fantasy, essential elements of a healthy, satisfying mental life. Mind-wandering with positive thoughts enables the mind to escape the constraints of the current situation and explore novel solutions.
Understanding the Preferences for Online Learning
Authors: Williams Geoffrey Alan
Published: June 2020

Online learning is promoted by the Malaysian Government as a key element in the Higher Education Blueprint 2015-25 (Shift 9: Globalized Online Learning), but research in the Malaysian context is very underdeveloped. This chapter aims to fill part of this gap with a simple analysis of online Master of Business Administration (MBA) courses to examine the appetite and preferences of actual and potential MBA students for online learning. Using data from local and international students studying on MBA programs in Malaysia, the authors show that the MBA students in their sample still have a largely instrumental view of the value drivers of their study programs. The key factors identified by the largest number of groups were facilities, price, certificate authenticity, duration, and flexibility of course times.
Considering the Fourth Quadrant Learning
Authors: Huah Goh Lay
Published: June 2020

This action research reports the experiences of introducing blended learning in the delivery of a post-graduate course to students in the university. The research conceptual framework is adapted from the technology acceptance model. The objective is to assess the level of acceptance of online learning and to document the attempts of the facilitator to create an independent, student-directed, and student-centered learning environment. This is the fourth quadrant learning typology. The research participants were a group of Masters in Education students who registered for the course “Strategies for Teaching and Learning.” Blended learning was introduced as a variant from the standard face-to-face instruction. This proved to be a valuable learning experience for both participants and lecturer. The perceived usefulness and perceived ease of use of online learning was not matched with the behavioral intention.
Arguing for the Self Through Activism
Authors: Duffy Mel
Published: June 2020

This article focuses on the reflections of negotiating the self—specifically, myself—during the 2015 referendum for Marriage Equality in Ireland. It focuses on the understandings and/or meanings that were conveyed to the LGBT community during the campaign. It could be formulated as the attempts by the last vestiges of societal institutions to shape society to their way of thinking—or rather, to maintain a status quo that had long passed. It was an experience in knowing how, why, and what was thought of the LGBT community, with no avenue for retort. It was the battlefield for the maintenance of a socialisation process which informed us of our place. The referendum became the articulation of the known as seen and embraced by the majority to be one day reproduced by the young. Within this context, a re-examination of the self was forced to emerge battered and bruised, but alive.
Production Chains of Soft-Weak Stones: Life Cycle Inventory of Techniques and Technologies
Authors: Bianco Isabella , Blengini Gian Andrea
Published: June 2020

The dimension stone sector is more and more active in developing new solutions to improve the sustainability of its supply chain, partly as a consequence of the current EU policies on Circular Economy and Raw Materials. The Life Cycle Assessment (LCA) is a recognized scientific tool for evaluating environmental impacts of the processes. Nevertheless, in the stone sector, LCA is hindered by the scarce availability of Life Cycle Inventory (LCI) datasets for the specific processes of the stone supply chain. This paper provides LCI datasets of the most common and widespread techniques and related technologies for quarrying, cutting and finishing soft-weak stones. To this aim primary data were collected in Italian marble quarries and processing plants and in companies producing cutting tools. When necessary, industry data were complemented with secondary data from literature. High replicability and flexibility of the datasets is obtained through the provision of Unit process inventories for each technology/technique and through the set of parameters. In addition, the uncertainty of the resulting LCI datasets has been evaluated with the well-established procedure of Ecoinvent pedigree matrix. The availability of these datasets contributes to the population of Life Cycle databases and is expected to boost the measurement and enhancement of the key aspects of sustainability in the stone sector.
Stone Materials and Old Buildings: How Observations can Help to Preserve the Past for the Future
Authors: Costa Antônio Gilberto
Published: June 2020

Through the observation of the set of monuments of cultural heritage built in stone, it can be seen important ornamental or covering applications. From macroscopic descriptions performed in these monuments, a great variety and different intensities of alteration processes are observed, mainly when comparisons are made between monuments located in large and small urban centers. These alterations and degradations, in part conditioned by the mineralogical composition and the structures present in these stone materials, are strongly influenced by the conditions of the environment. In general, the set of alterations and degradations observed are those related to the decomposition of the minerals that make up these rocks. Based on these in-situ investigations, diagnostics can be produced on the degree of degradation of stone materials and recommendations for their conservation
Insertion of Silicon Carbide as Cutting Element in Ecological Fickerts for Dimension Stone Polishing
Authors: de Almeida Phillipe Fernandes , Ponciano Victor Moza , da Silveira Leonardo Luiz Lyrio , Sichieri Eduvaldo Paulo
Published: June 2020

The dimension stone polishing consists of eliminating the surface roughness of the slabs with the use of fickerts. The main tools used for this activity are composed of epoxy resin, derived from petroleum, which contains chemical elements with harmful potential to the environment and human health. To overcome this problem, it is necessary to develop new technologies with the lowest environmental impact in the life cycle, from the raw material acquisition to the waste disposal. This study aims to contribute to the improvement of an ecological fickert developed by the Centre for Mineral Technology (CETEM). The fickerts presented here are composed of castor oil resin, silicon carbide and silica from rice hull ash. Two different compositional formulas were used for the preparation of the pieces that were tested in an industrial polishing machine. The results showed that the formula with higher percentage of fillers showed better performance, expressed by the relation between the loss of mass of the pieces and the increase of gloss on the surface of the slab. Other particularities of the product, as the high abrasion resistance of the matrix that reduced the cutting function, could be solved by choosing a filler with a lower hardness. This fact allows to infer that this line of research presents great potential of applicability in the dimension stones market.

Published: June 2020

Six Portuguese magmatic ornamental stones were submitted to Soxhlet experiments during 10,000 hours (approximately 416 days) in order to evaluate how the rain water affects the rock behavior as a dimension stone. Macroscopic alterations were observed in the rock fragments and chemical analysis of leaching water solutions revealed how major elements were mobilized from rock-forming minerals allowing to compare weathering susceptibilities between different natural stones.
Ecological Fickerts Used in the Dimension Stones Polishing Reinforced with Silica from the Rice Hull Ash
Authors: Dorigo Wana Favero Gaburo , da Silveira Leonardo Luiz Lyrio , de Almeida Phillipe Fernandes
Published: June 2020

The processing stages of the dimension stones industry uses inputs mainly from petroleum-derived chemicals that can cause damages to the environment and to the human health. Therefore, there is a need to develop more ecological and sustainable technologies aiming to replace the conventional inputs by less aggressive ones. From this, ecological fickerts made from polyurethane castor oil resin (Ricinus communis L.), silicon carbide (SiC), silica from rice hull ash (RHA) and synthetic diamonds were developed in order to compare them with the epoxy resin fickerts currently used in industry. For such, each half of a Brazilian granite slab was polished using each different type of fickerts and the gloss measures results were compared. It was found that the side of the slab polished using the ecological fickerts presented brightness values about 10 Gloss Units (GU) greater than the other side polished with the conventional abrasives. In addition, the ecological fickerts presented lower wear values, and consequently lower mass loss compared to the conventional ones. These results indicate that the ecological fickerts are a good alternative to the dimension stones polishing, even considering sustainability aspects and more eco-efficiency inputs materials.

Published: June 2020

In this work, finite element method was used to determine the normalized stress intensity factors for different configurations. For this, a 2-D numerical analysis with elastic behavior was undertaken in pure I mode. This simulation was carried out using a numerical calculation code. On the basis of the numerical results obtained from the different models treated, there is a good correlation between the nodal displacement extrapolation method (DEM) and the energy method based on the Rice integral (J) to evaluate the normalized stress intensity factors and this for different crack lengths. For each configuration, the increase in the crack size causes an amplification of normalized intensity stresses fators.

Published: June 2020

The study focus on maintain of voltage factor in the near-unity network (1pu) using a Static Variables Compensator (SVC). In order to determine the effectiveness of this device to improve the stability of a power system with distributed genetartion in presence of wind farm based on MADA, the power flow is calculated without the existence of the SVC at first, and then when the SVC is integrated. This operation is performed to make a comparison and evaluate the role of the device in the system. However, in order to improve voltage stability as well as minimize power losses for practical power systems, it is important to locate the appropriate place of SVC. Various methods have been developed. The particular CPF method has been proven effective in determining SVC placement. The obtained results are discussed and analysed, it is found that this device provides a considerable reduction in the voltage drop and appreciable control of the voltage at the concerned busbar.

Published: June 2020

Cyprinidae, the largest known fish family including carp and minnows, has worldwide distribution with many species that are economically important in aquaculture. As would be expected, many viral pathogens can affect this group. The most pathogenic of these are the rhabdoviruses, a reovirus and three herpesviruses. Cyprinid herpesviruses can cause significant economic losses in aquaculture, and some of these viruses are oncogenic. The three herpesviruses are closely related but cause distinctly different diseases. Fish pox, caused by cyprinid herpesvirus 1 (CyHV-1), is one of the oldest known fish diseases, being recorded as early as 1563. It takes the form of a hyperplastic, epidermal papilloma on common carp. Cyprinid herpesvirus 2 (CyHV-2) is causative agent of herpesviral hematopoietic necrosis (HVHN). The herpesvirus was first isolated from cultured goldfish in Japan. It causes a severe epizootic but no external clinical signs were apparent on affected fish. One of the most economically important and researched viral diseases of carp is koi herpesviral disease caused by cyprinid herpesvirus 3 (CyHV-3). The aim of this paper is to present the current knowledge on herpesvirus diseases of the cyprinids.

Dermanyssus gallinae or the poultry red mite is currently the most im-portant ectoparasite aff ecting egg-laying hens in several countries causing reduced poultry welfare, mortality and even allergic reactions in poultry farms workers. Its short life cycle, which in optimal conditions can be com-pleted within 7 days, and ability to survive in extreme circumstances with-out a blood meal up to 13 months, and the ability to infest new fl ock, makes it even more diffi cult to eradicate. Dermanyssus gallinae prevalence rates in diff erent European countries, including Serbia, can reach up to 80-90%. Also, the poultry red mite is responsible in vector transmission of several bacterial and viral avian diseases, including Salmonella spp, Chlamydia spp., Escherichia coli, Staphylococcus spp., Pasteurella multocida, Newcas-tle disease and Fowl poxvirus. Besides that, the poultry red mite can also transfer antimicrobial resistance genes by carrying pathogenic bacterial fl ora. Control of Dermanyssus gallinae can be divided into conventional and alternative methods. Conventional methods are mostly focused on pre-venting infestations and/or killing Dermanyssus gallinae, while alternative methods include the use of essential oils, vaccines, light, odors, predatory mites, fungi, nematodes and bacterial endosymbionts, and temperature in order to eliminate the poultry red mite. Nevertheless, this small ectopara-site still makes millions worth damage to global poultry industry.

The past decades of clinical practice in poultry farming are character-ized by inadequate control of one of the most important poultry ectopara-site, the red poultry mite (Dermanyssus gallinae). Therefore, the program for control of D. gallinae based exclusively ona physical mechanisms of action of acaricides has been developed in Serbia since 2012. By the beginning of 2017, a synergistic relationship between paraffi n and silicone oils was observed by our team, and its effi ciency in preventing the red poultry mite from respiring was examined. For laboratory examination the Petri dish and tin-box methods were used. Direct, full 1-minute exposure of adult mites to the recommended (15 and 20%) or even much lower concentration of the formulation resulted in 100% mortality aft er 24 hours. Subsequent 1-hour exposure (24 hours aft er application onto treated non-absorbent surface of adult mite) resulted in 100% mortality with the same concentrations. The long term eff ect depends on the surface quality. The concentrations of 15 and 20% provide 100% long-term eff ect aft er a 1-hour exposure period, and remains fully eff ective over the following 4-month period. In the following months (8 months), the formulation continues to work with a slightly lesser, however, still signifi cant eff ect. The formulation is most eff ective on a plastic surface, where the full eff ect is achieved with signifi cantly lower concentrations. The formulation has no eff ect on eggs; however, aft er the short development cycle is completed in the egg (2-6 days) and exit from the shell, the larva is immediately exposed to the eff ects of the formulation and eliminated. High effi ciency of the paraffi n and silicone oils formulation, which has been established in laboratory conditions, justifi es its use to the purpose of D. gallinae control in cages and equipment before fl ock settle-ment as well as in transport cages aft er cleaning and disinfection.

The generally accepted approach to D. gallinae control is based on the control of infestations. The reduction of D. gallinae infection to an acceptable level can temporarily prevent its harmful effects on the health status ofpoultry. However, the reduced number of D. gallinae continues to persist in poultry environment resulting in an intensive increase of infestation rate and consequent transmission of infectious and contagious diseases. Contrary to suppression, the eradication approach completely eliminates D. gallinae thus improving general health status of the flock and providing the control of infectious and contagious diseases associated with this organismand eliminating other adverse effects. Biological efficiency and selection of inert compounds was performed in laboratory conditions. The previous experience with application of SiO2 formulations in practice confirmed thepossibility of successful eradication in 8 cases (combined application of liquid and powdered form). New generation of inert compounds (P 547/17)  showed a range of superior properties as compared with SiO2 formulations,especially in view of high and long-lasting residual effects on non-absorbent surfaces. In laboratory conditions, after 7 months, the layer formed by a 20% working emulsion on a metal substrate exhibited efficiency of 92%after 1-hour exposure. In clinical conditions, the presence of mites was not detected even after 6.5 months of the settlement of the flock. Clinical tests of inert oils are still ongoing, but their high potential for the eradication of D.gallinae The eradication of D. gallinae is highly complex procedure, which cannot be performed at all times and in all conditions. The conditions for the eradication of D. gallinae using inert compounds include adequate hygienic preparation of the facilities while still empty, adequate application of selected compounds, and then adequate ambient temperatures which leads to increase of mites activity. The program of D. gallinae control includesprocedures for the preparation, implementation, eradication checks, and prevention of re-infestation

The hatcheries may become contaminated with pathogenic bacteria which could spread in the hatchery through the air. That is why the implementation of an effective cleaning and disinfection program and the maintenance of good hygiene are extremely important for the normal course of production and for reducing the spread of infectious agents. In this study, data on the degree and dynamics of bacterial contamination in a poultry hatchery are presented. In the incubation sector, bacterial contamination on the surfaces was found to be low-level ranging from 0.25 to 4.43x101 CFU/ cm2 but in the air it was strongly influenced by the hatching. In the hatchery sector, bacterial contamination on the surface and in the air was high, with the highest values found on the egg shells (1.77x106 CFU/cm2), on the floor (3.2x104 CFU/cm2) and in the air (1.77x105 CFU/cm3) of hatcher cabinets during hatching. The results obtained show that the most important source of microbial contamination in the hatchery is the hatchery sector, especially during hatching, when highly contaminated materials as fluff, shells and dried secretions are released. In case of poor organization of working process, the bacteria could spread by air and contaminate the other sectors of the hatchery. The study confirms the importance of a different approach in the development of preventive measures, depending on the degree of risk in different zones in the hatchery, which is the basis for the effective management practice aimed at decreasing microbiological hazards in hatcheries.

During 2017, 784 insect samples were examined and the presence of Culicoides spp. was established in 25.51% of samples. Earlier research has found that the dominant population of Culicoides spp in Serbia belongs to Obsoletus complexes, established in 60.05% of analyzed samples. Out of the entire insect population analyzed, males were found in 22.84%, unpigmented (young) females in 67.97%, females who took blood in 7.39%, whereas 1.35% were gravid females. Culicoides spp. from the Pulicaris complex was established in 38.85% of examined samples. Males were found in 18.91%, unpigmented (young) females in 71.72%, females who took blood in 9.09%, and 1.11% were gravid females. Other types of culicoids have been established in less than 10% of the examined samples. During examination, the most prevalent species were Culicoides obsoletus, C. picturalis, C. lupicaris, C. scoticus and C. fascipennis.

West Nile virus (WNV) is arbovirus distributed all around the world. In humans, 80% of infection cases are asymptomatic. In 20% of infected people, a febrile self-limiting illness is reported. WNV has the potential for fatal neuroinvasive disease. In 1% of cases, the infection may result in neuroinvasive disease with permanent neurological consequences or death outcome. Neurological forms may vary presenting with encephalitis, meningitis, meningoencephalitis or acute flaccid paralysis. Outbreaks with neurological forms of WNV infection were recorded in different areas of Greece, Italy, Romania, Hungary and Serbia. During the period from 2013 to 2016, 114 samples of cerebrospinal fluid and 107 serum samples were taken from 114 patients suspected of WNV neuroinvasive disease (WNND). The presence of specific anti-WNV IgM and IgG antibodies in cerebrospinal fluid (CSF) and sera samples were tested by WNV IgM and IgG ELISA (Euroimmun, Germany). In addition, 48 samples of CSF or/and serum of people with suspected WNV infection were examined by commercial molecular tests - real time RT-PCR (WNV Real-TM, Sacace biotechnologies, Italy). The IgM antibodies against WNV were present in 25.4% (29/114) of CSF samples, and in 31.8% (34/107) of serum samples tested from 114 patients suspected of WNND. The IgG antibodies against WNV were detected in 3.5% (4/114) of CSF samples, and in 11.2% (12/107) of serum samples. The WNV RNA was detected by real time RT-PCR test in 7 out of 48 (14.6%) CSF or/and serum samples. In this study, detection of IgM antibodies in CSF is more frequent than detection of WNV RNA in CSF or serum samples. WNV RNA detection in CSF is confirmatory diagnostic test but has limited utility in the diagnosis of WNV neuroinvasive disease due to low viremia level at the time of clinical presentation of the disease. The limitations in the use of ELISA IgM test are linked to cross - reactivity among flaviviruses and long persistence of IgM antibodies in the serum and CSF.

This article reports on the occurrence and diagnosis of Aujeszky’s disease in a dog. The procedure for isolation and identification of Aujeszky’sdisease virus was described. A dog of unknown breed aged about two years died of Aujeszky’s disease after consuming animal offal (internal organs: lungs, spleen, kidneys) fed by the owner after slaughtering piglets and preparing meat for cooking. As early as 24 hours after consuming the offal, the dog manifested characteristic symptoms of Aujeszky’s disease, which were immediately recognized by the veterinarian. The death occurred within less than 24 hours upon first clinical signs of disease. Aujeszky’s disease virus was isolated and identified from brain and internal organ (lung and spleen) samples of the dog at the Department of Virology of the Scientific Veterinary Institute „Novi Sad“. Isolation and identification of the virus was performed on PK-15 porcine kidney cell line and using nested PCR technique.
