Organisations financières et diversité du capitalisme financier : le cas des fusions-acquisitions en France
Authors: Thine Sylvain , Tadjeddine Yamina
Published: June 2020

Les opérations de fusions-acquisitions sont des moments particuliers sur le marché du capital car elles finalisent un arrangement marchand : le capital d’une PME ou la filiale d’un groupe qui n’existait pas en tant qu’objet échangeable librement sur un marché se trouvent dotés de qualités marchandes, d’une valeur financière et font l’objet d’un achat. Nous proposons dans cet article une caractérisation socio-économique des intermédiaires financiers à travers trois échelles : les organisations, les pratiques et les employés. Nous mobilisons la base Carfi qui a recensé 363 opérations de Fusac en 2010 en France. Nous avons complété cette base en ajoutant le niveau des organisations financières. Une ACM et une CAH ont été menées afin de caractériser les organisations financières comme un espace social construit à partir de fonctions économiques, de pratiques financières et d’individus socialement situés. Nous distinguons trois formes de capitalisme financier : le capitalisme bancaire impliquant les banques européennes, le capitalisme financier lié à la présence de banques d’investissement issues notamment du monde anglo-saxon, et le capitalisme financier d’entreprise associé à des conseillers indépendants.
Sur fond de crise socio-écologique du capitalisme, la théorie de la valeur revisitée
Authors: Harribey Jean-Marie
Published: June 2020

La crise écologique a entraîné la recherche théorique dans plusieurs directions. Une « économie de l’environnement » s’est constituée au sein de la théorie néoclassique afin de prendre en compte la « valeur de la nature ». Une autre réflexion est née pour élaborer de nouveaux indicateurs de richesse. Il existe aussi une problématique marxienne de l’écologie inscrite dans les rapports sociaux. La révolution technique de l’information et l’enjeu des communs bousculent les catégories de valeur et de richesse. Ce texte examine ces questions en présentant d’abord ce que fut le premier débat théorique à la naissance de l’économie politique et qui perdure jusqu’à aujourd’hui : la richesse ne se réduit pas à la valeur économique. Puis, il montre en quoi la valeur est une catégorie sociale qui permet de prendre en compte la question écologique. Enfin, il discute l’hypothèse de dépassement de la catégorie valeur.
Le sentiment de solitude dans la vieillesse
Authors: Aouici Sabrina , Peyrache Malorie
Published: June 2020

La lutte contre la solitude est devenue un véritable enjeu de santé publique pour la population en général comme pour les personnes âgées, pour lesquelles l’isolement social entraîne la perte d’autonomie. Même si la solitude ne touche qu’une partie de la population, des événements tels que la canicule de 2003 en France ont révélé, dans l’opinion publique, la vulnérabilité de nombreuses personnes âgées face à la solitude. Le sentiment de solitude est à distinguer de l’isolement avec lequel il est souvent confondu. L’isolement ou l’exclusion peuvent néanmoins être à l’origine ou favoriser le sentiment de solitude, tout comme la précarité et les inégalités qui en découlent. Nous proposons d’interroger ce sentiment de solitude au regard des inégalités sociales et matérielles. Cette réflexion s’appuie sur la vague 6 de l’enquête européenne Share ( Survey on health, ageing and retirement in Europe ) menée auprès de personnes âgées de 50 ans ou plus. Il s’agit d’une analyse des indicateurs de précarité sociale et matérielle qui recensent les ressentis et les conditions de vie des personnes interrogées. À partir de statistiques descriptives et de régressions logistiques, notre étude tentera de mettre en lien le sentiment de solitude selon trois axes : la précarité économique et matérielle, la précarité sociale et relationnelle, ainsi que la fragilité-précarité.
Compétences politiques et épuisement émotionnel : analyse d’un effet médiateur modéré
Authors: Rudelle Astié Anne , Dagot Lionel
Published: June 2020

Dans le cadre théorique de la Conservation des Ressources (Hobfoll, 1989), l’objectif de cette étude est d’approfondir la recherche sur les mécanismes au travers desquels les compétences politiques influencent l’épuisement émotionnel. Ainsi, cette étude examine l’effet médiateur de l’autonomie au travail sur la relation entre les compétences politiques et l’épuisement émotionnel. De plus, cette étude prend en compte la réaction des individus aux compétences politiques lorsqu’ils perçoivent une prise de décision politique au sein de leur organisation. Elle analyse donc l’effet modérateur de la prise de décision politique sur la relation entre les compétences politiques et l’autonomie au travail. Les résultats de l’enquête menée auprès de 123 salariés français montrent que les individus aux compétences politiques développées expriment une autonomie accrue qui en retour diminue leur épuisement émotionnel. D’autre part, la prise de décision politique représente un contexte modérateur qui interagit avec les compétences politiques pour renforcer les sentiments d’autonomie. Les limites de cette étude et des directions pour de futures recherches sont également discutées.
La vacunación: estrategia fundamental en la eliminación de la viruela en Cuba (1804-1923)
Authors: Beldarraín Chaple Enrique
Published: June 2020

Las epidemias de viruela azotaron a Cuba desde 1522, produciendo elevada morbilidad y mortalidad. En 1804, se inició la estrategia de vacunación contra esta enfermedad que, con distintos avatares y fases en su desarrollo, tuvo como figura central a Tomas Romay. El objetivo del trabajo fue analizar los resultados de la estrategia de vacunación llevada a cabo en la eliminación de la viruela en Cuba y como se transformaron las instituciones en relación a los avances y producción de la vacuna en función del contexto científico, social y político del periodo estudiado. Las fuentes primarias utilizadas han sido diversas: fuentes de tipo epidemiológico y estadístico, documentos relacionados con los organismos puestos en marcha para la propagación y producción de la vacuna, informes institucionales y periodismo científico local. El trabajo reconstruye el papel jugado por la Junta Central de la Vacuna (1804), para planificar, ejecutar y expandir esta estrategia en el territorio, el Instituto de Vacunación Animal (1873) y el Centro General de la Vacuna (1883) en la producción de la misma. En el siglo XX, se convirtió en obligatoria por ley y junto a las estrictas medidas de aislamiento tomadas sobre los casos y los controles de focos, llevaron a la eliminación de la enfermedad a partir de 1923.
Maestros de la navegación: el dominio técnico de la movilidad fluvial en el mundo andino
Authors: Medina Muñoz Lina Rocío
Published: June 2020

Este artículo presenta una mirada panorámica de las técnicas de navegación fluvial desarrolladas por la población in­dígena en el mundo andino, con el propósito de discutir la visión dicotómica que convencionalmente distingue entre los saberes tradicionales y los conocimientos científicos. Se describen los materiales, utensilios y prácticas de navegación utilizadas por los indígenas y se intenta visibilizar el conocimiento tácito arraigado en esta cultura técnica. Se explica cómo fueron adaptadas al contexto americano las tecnologías traídas por los españoles y se muestra que los conocimientos técnicos tradicionales fueron un factor útil incluso para el éxito del propio proyecto de dominación europeo. Se argumenta que el flujo mutuo de conocimientos y las hibridaciones tecnológicas surgidas a partir del encuentro entre ambas civilizaciones cuestiona la común inferiorización del saber tradicional con respecto al conocimiento científico.
Life-Writing, Subjectivity, Art: Keith Douglas in Egypt During the Second World War
Authors: RUMMEL Andrea
Published: June 2020

This paper argues that Keith Douglas’s art is centrally about the condensation or simplification of emotion into image. It examines Douglas’s approaches to writing war. By looking at the several modes of Douglas’s war writing (autobiography, letters, poetry and the short story), it traces the evolution of the autobiographical into the poetical and outlines Douglas’s aesthetic strategies of turning (war) experience into art or, on a more general level, demonstrates how life-writing translates itself into poetry.
Quotatifs et ethos interactionnel : quelques fonctions de l’introducteur BE LIKE
Authors: FUCHS Yann
Published: June 2020

Depuis l’apparition de deux nouvelles formes en son sein – le verbe GO et, de façon plus remarquable encore, la construction BE LIKE – le système quotatif de l’anglais a fait l’objet de nombreuses études visant à caractériser ces deux nouveaux introducteurs. Dans la mesure où la sémantique pure se révèle peu opérante dans cette entreprise, la plupart des travaux sur la question ont en commun la recherche des fonctions pragmatiques et discursives nouvellement acquises par ces marqueurs. Cependant, bien qu’ils soient encore principalement employés en conversation orale informelle, ils font l’objet de peu de considérations d’ordre réellement interactionnel. Cet article propose d’entamer une réflexion sur les fonctions interactionnelles du quotatif BE LIKE, notamment en tant qu’il intervient dans la construction de l’ethos en interaction. Cette construction se décline ici selon deux modalités : d’une part, l’assertion et le maintien du statut d’émetteur-narrateur au détriment de l’alternance naturelle des tours de parole et, d’autre part, la prise de position intersubjective et l’alignement qui en découle. À la faveur de quelques exemples de conversation réelle, cet article défend la nécessité d’envisager la transmission de contenus pragmatiques au-delà des schémas unilatéraux qui caractérisent parfois l’analyse du discours, dans le cas particulier des quotatifs en interaction.
The four basic errors of special theory of relativity and the solution offered by extended Galilean relativity
Authors: Klinaku Shukri
Published: June 2020

Is the special theory of relativity (STR) a “simple” or “tricky” theory? They who think that it is a simple theory say (i) that its postulates are simple, that Nature is such, (ii) that the mathematics of STR is perfect, and (iii) that experiments support it.
I consider its two postulates to be very true, whereas the mathematics of the STR has a shortcoming, and, as for the experiments, the question must be posed: which theory do they support best? The problem for STR lies in the transition from its postulates to its basic equations, i.e., Lorentz
transformation and the velocity addition formula. The passage from the principle of relativity and the constancy of the speed of light to the basic equations of the STR is affected by four fundamental errors—three physical and one mathematical. Continuous attempts to reconcile these
latent mistakes have made STR increasingly tricky. As a result, it is in a similar situation to Ptolemy's geocentric model after “improvements” thereto by Tycho Brahe. However, the “Copernican solution” for relative motion—offered by extended Galilean relativity—is
very simple and effective.
MAGNETOENCEPHALOGRAPHY–ELECTROENCEPHALOGRAPHY CO-REGISTRATION USING 3D GENERALIZED HOUGH TRANSFORM
Authors: Lin Sheng-Kai , Lo Rong-Chin , Lee Ren-Guey
Published: June 2020

This study proposes an advanced co-registration method for an integrated high temporal resolution electroencephalography (EEG) and magnetoencephalography (MEG) data. The MEG has a higher accuracy for source localization techniques and spatial resolution by sensing magnetic fields generated by the entire brain using multichannel superconducting quantum interference devices, whereas EEG can record electrical activities from larger cortical surface to detect epilepsy. However, by integrating the two modality tools, we can accurately localize the epileptic activity compared to other non-invasive modalities. Integrating the two modality tools is challenging and important. This study proposes a new algorithm using an extended three-dimensional generalized Hough transform (3D GHT) to co-register the two modality data. The pre-process steps require the locations of EEG electrodes, MEG sensors, head-shape points of subjects and fiducial landmarks. The conventional GHT algorithm is a well-known method used for identifying or locating two 2D images. This study proposes a new co-registration method that extends the 2D GHT algorithm to a 3D GHT algorithm that can automatically co-register 3D image data. It is important to study the prospective brain source activity in bio-signal analysis. Furthermore, the study examines the registration accuracy evaluation by calculating the root mean square of the Euclidean distance of MEG–EEG co-registration data. Several experimental results are used to show that the proposed method for co-registering the two modality data is accurate and efficient. The results demonstrate that the proposed method is feasible, sufficiently automatic, and fast for investigating brain source images.

Authors: Papadakis Stamatios , Kalogiannakis Michail
Published: June 2020

It is widely known that when used intentionally and appropriately, technology and interactive media are effective tools to support learning and development. In recent years, there has been a push to introduce coding and computational thinking in early childhood education, and robotics is an excellent tool to achieve this. This chapter presents some results obtained in the development of a learning experience in computational thinking using Bee-Bot educational robotics. The experience involved 47 preschoolers of a kindergarten in Crete, Greece during the period 2019-2020. The study reports statistically significant learning gains between the initial and final assessment of children's computational thinking skills. It was found that children in the treatment group who engaged in the robotic curricular intervention performed better on CT tests. This finding shows that an enhanced teaching experience using robots was beneficial for improving young children's computational thinking skills. The implications for designing appropriate curricula using robots for kindergarteners are addressed.

High-voltage air power lines (AL) are sources of danger to aircraft objects and of pollution of the surrounding environment by their fields. In this connection, there is a problem of creating of analytical mathematical models for the calculation of the magnetic and electric fields of air power lines (AL) in the surrounding them space. The analytical mathematical models for magnetic and electric fields of air power lines (AL) in surrounding space for making subsequent decisions in the field of detection of high-voltage air lines by aircraft and electromagnetic pollution of environment were obtained.
Spatiotemporal distribution and trend of COVID-19 in the Yangtze River Delta region of the People’s Republic of China
Authors: Ye Lei , Hu Lingqian
Published: June 2020

An outbreak of atypical pneumonia, now called COVID-19 and known to be caused by the novel coronavirus SARS-CoV-2, first detected in Wuhan, Hubei Province of the People’s Republic of China in December 2019 and afterwards rapidly spread worldwide. Wuhan and the Yangtze River Delta (YRD) region implemented first-level public health emergency responses to stop the spread of the virus on January 23rd, 2020. We tracked the geographical gravity centre of the disease and calculated spatial autocorrelation to explore the spatiotemporal patterns of distribution of imported and locally disseminated COVID-19 cases under the emergency-response control measure. We also applied polynomial regression analysis to estimate the trend of the COVID-19 in the YRD region before and after the control activities against the spread of the infection were instituted. The results show that the control measures applied have been effective. And, in the YRD region, areas with a large influx of population flow from Wuhan and Hubei Province had high risks of COVID-19. Therefore, identification of the spatiotemporal trends should be the first step when developing effective policies to manage and control any new epidemic. The results are not only informative locally but also useful for the rest of the world.

Published: June 2020

Splenic artery pseudoaneurysm is a rarely described condition and it is even more rarely considered as a complication of peptic disease. The most common etiologies are pancreatitis, both chronic and acute, and trauma. Diagnosis can be challenging, including ultrasonography, computed tomography scan and angiography, the latter being useful also for therapy (embolization). Given her history of bulimia nervosa and the stress related to hospitalization, our patient was particularly predisposed to peptic ulcer.

The COVID-19 outbreak is having a significant impact on both cardiac rehabilitation (CR) inpatient and outpatient healthcare organization. The variety of clinical and care scenarios we are observing in Italy depends on the region, the organization of local services and the hospital involved. Some hospital wards have been closed to make room to dedicated beds or to quarantine the exposed health personnel. In other cases, CR units have been converted or transformed into COVID-19 units.  The present document aims at defining the state of the art of CR during COVID-19 pandemic, through the description of the clinical and management scenarios frequently observed during this period and the exploration of the future frontiers in the management of cardiac rehabilitation programs after the COVID-19 outbreak.
Rapid Weight Gain: An Unusual Presentation of Leukemia
Authors: Srinivasan Ranjini , Thomas Sarita
Published: June 2020

Neurological manifestations of leukemia can be due to direct effects of the malignancy or due to the indirect effects of infection or therapy. An 11-year-old boy presented with recent-onset weight gain with papilledema and a history of tuberculosis contact. Neuroimaging and initial microscopic examination of the cerebrospinal fluid (CSF) did not aid in the diagnosis of central nervous system leukemia. He was started on antitubercular treatment yet deteriorated. Repeat CSF analysis when subjected to cytospin and flow cytometry confirmed the diagnosis of B cell acute lymphoblastic leukemia (ALL). Although there have been reports of relapsed ALL presenting as obesity, isolated rapid changes in weight at initial presentation are a very rare and unusual manifestation of ALL. To the best of our knowledge, this is the first such report.
Relative vertex asphericity
Authors: Harlander Jens , Rosebrock Stephan
Published: June 2020

Diagrammatic reducibility DR and its generalization, vertex asphericity VA, are combinatorial tools developed for detecting asphericity of a 2-complex. Here we present tests for a relative version of VA that apply to pairs of 2-complexes
$(L,K)$
, where K is a subcomplex of L. We show that a relative weight test holds for injective labeled oriented trees, implying that they are VA and hence aspherical. This strengthens a result obtained by the authors in 2017 and simplifies the original proof.
Singular genuine rigidity
Authors: Florit Luis A. , Guimarães Felippe
Published: June 2020

We extend the concept of genuine rigidity of submanifolds by allowing mild singularities, mainly to obtain newglobal rigidity results and unify the known ones. As one of the consequences, we simultaneously extend and unify Sacksteder and Dajczer–Gromoll theorems by showing that any compact

n

-dimensional submanifold of

\mathbb R^{n+p}

is singularly genuinely rigid in

\mathbb R^{n+q}

, for any

q < \mathrm {min}\{5, n\}–p

. Unexpectedly, the singular theory becomes much simpler and natural than the regular one, even though all technical codimension assumptions, needed in the regular case, are removed.

Electrical conductivity and acidity of honey
Authors: Živkov Baloš Milica , Popov Nenad , Vidaković Suzana , Ljubojević Pelić Dragana , Pelić Miloš , Mihaljev Željko , Jakšić Sandra
Published: June 2020

In this paper, the electrical conductivity and concentration of free acids (acidity) of various types of honey collected from the area of Vojvodina was investigated. Physicochemical analyzes of parameters such as electrical conductivity and acidity of honey have an important role in defining the overall properties of honey and assessing the quality of honey. A total of 55 samples of honey were examined. Out of the total number of samples, 5 samples did not meet the requirements of the Republic of Serbia Regulations on quality of honey due to inadequate electrical conductivity. Free acid values measured in tested samples ranged from 1.5 to 30 mEq / kg, and the values of electrical conductivity were in the range between 0.08 and 1.99 mS/cm. Our assumption that there is a correlation between the tested parameters has been confirmed only in meadow and polyfloral honey. Further research on the physicochemical properties of Serbian honey is recommended and important in order to establish certification marks and criteria for assessing the quality of Serbian honey.

The aim of this study is to summarize the data on the occurrence, presence and prevalence of some zoonotic flaviviruses, which have been actively circulating in the territory of the Republic of Serbia during past decade. The genus Flavivirus, family Flaviviridae,encompasses vector-transmitted viruses with zoonotic potential. The genus is comprised of more than 70 viruses transmitted to humans by mosquitoes and ticks. Some of those are associated only with human diseases (such as yellow fever and dengue fever), whereas others can cause diseases in both humans and animals. Animals are major reservoirs and primary hosts for the latter group. The virus transmission to other animal species or humans occurs via diverse vectors – mostly mosquitoes and ticks. A range of these virus species is widely distributed worldwide, especially in tropical and sub-tropical climatic zones. Some representatives of these species have only recently been identified at the territory of Republic of Serbia. This paper gives an evidence on the presence and distribution of West-Nile virus, tick-borne encephalitis (TBE) virus and Usutu virus that were conducted within the study in Serbia. The research pointed out the presence of recently detected West-Nile virus and Usutu virus as well as the current circulation of tick-borne encephalitis virus, for which only limited serological evidence on the presence of virus-specific antibodies in humans was available so far. In the aspect of public health, the full understanding of the importance of identification and prevalence of different flaviviruses still require further comprehensive entomologicalacarological, seroepidemiological, clinical and virological research.
CURRENTLY UNKNOWN ASPECTS OF POULTRY NECROTIC ENTERITIS PATHOGENESIS
Authors: Milanov Dubravka , Aleksić Nevenka , Živkov Baloš Milica , Pajić Marko , Knežević Slobodan
Published: June 2020

Necrotic enteritis (NE) or poultry clostridiosis is a disease which poses enormous health problems and makes tremendous economic losses to intensive poultry production worldwide. Despite having been targeted in extensive research for decades, a number of aspects of its pathogenesis remain unknown. For more than 30 years alfa-toxin has been considered to be the main virulence factor of the causative agent, but experimental research using a mutant Clostridium perfringens strain lacking the gene coding for this confirmed that alpha-toxin is not necessary for pathogenesis. Since the 1980s, NetB toxin has been the main suspected virulence factor. However, recently it has been discovered that the large clostridial cytotoxin named TpeL also contributes to the pathogenesis of NE. In spite of that, the prevalence of the genes which code for these toxins vary between the isolates of C. perfringens from the intestines of diseased poultry, which made clear that further investigation into their roles is necessary. It has been agreed that specific intestinal environmental conditions, which favour the growth and multiplication of C. perfringens, are key factors to the emergence of disease. Given that a battery of non-specific factors contributes to pathogenesis, as well as that it is impossible to eliminate them in intensive poultry production, not much hope remains that NE can be controlled. In this short review, the current knowledge on the pathogenesis of NE has been summarized.

Toxoplasma gondii is a ubiquitous coccidian protozoan that can infect a wide range of warm-blooded animals, including humans. For immunocompetent humans it is a well-adapted parasite that usually causes asymptomatic infection. However, in congenitally infected infants and immunocompromised patients it can cause a serious life threatening disease. The aim of this study was to determine the levels of anti-toxoplasma antibodies among residents of the South Backa District, Serbia. During the period from January 2014 to December 2018, sera from 11,288 persons from South Backa District were tested on the presence of IgM and IgG antibodies against Toxoplasma gondii, using ELISA test (Euroimmun, Lübeck, Germany). The testing was performed on the automatic device Euroimmun Analyzer I-2P. The avidity of IgG WNV antibodies was determined for IgG positive sera using commercial avidity test (Euroimmun, Lübeck, Germany). In total, out of 11,288 patients who were tested for toxoplasma antibodies, the results were positive for 2,513 (22.26%). In 2014 seropositivity for Toxoplasma gondii was 25.78% (464/1800), in 2015 it was 23.30% (400/1717), in 2016 it amounted 20.99% (474/2258), in 2017 it was 21.47% (529/2464) and in 2018 seropositivity was 20.96% (639/3049). Seropositivity of 26.53% (390/1470) was found in males and it amounted 21.62% (2123/9818) in females. Possible recent infection within the last 12 months was found in 1.70% (192/11288) patients. Possible acute infection or false - positive IgM result was detected in 1.31% (148/11288) patients. Past infection was found in 2173/11288 (19.25%) patients. Equivocal results were found in 1.48% of samples (167/11288). The lowest frequency of anti-toxoplasma antibodies was detected in pre-school children 13.07% (97/742) and the highest in persons older than 65 years 60.18% (65/108). Comparing the results of the research done from 2014 to 2018 with the data from 1989, a significant decline of seroprevalence in general population and women of generative age was found.

The characteristics of aging and the changes of cardiovascular system with aging are important in clinical decision making and in designing preventive measures. Studies of aging in dogs represent paradigm in biomedical researches. Aging leads to numerous changes of cardiovascular system, which could be looked from morphological, functional, endocrinological, genetic and biochemical points of view. These aspects of aging enable many diagnostic procedures, therapeutic procedures and preventive measures as well. In this paper special emphasis was put on changes of cardiovascular system, caused by aging, which are clinically free to registered or may be affected by therapy or prophylaxis.

Published: June 2020

Diagnostics of the uterus and fertility control include clinical, bacteriological, cytological and histopathological examinations. Bacteriological studies should be accompanied by cytological and pathological tests, because the presence of inflammatory processes is the most important for diagnosis and prognosis. Although, there is no standard method for the interpretation of cytological examination results for endomentrium, the examination of cytologic swabs from the surface of the uterine mucosal surface is a simple and noninvasive method used as a supplementary examination in mares. In our country this method is recommended in veterinary practice, primarily for the diagnosis of endometritis. Key words: mare, uterus, smear, cytology.

Production of good quality milk with proper biological characteristics is provided from milk udder in good health condition. This paper presents the results of examining the mammary glands of dairy cows in Branicevo district. Standard bacteriological methods were used for bacteriological isolation and identification of mastitis pathogens. The prevalence of mammary infection in the area was 2.14%. The most common cause of mastitis was Staphylococcus aureus. For proper prevention and treatment of mastitis, good hygiene measures should be undertaken during milking, ensuring proper equipment, good nutrition and effective treatment in the cases of udder diseases.
NEUTROPHIL TO LYMPHOCYTE RATIO IN EARLY LACTATION AS A PREDICTOR FOR FUTURE EXCLUSION OF DAIRY COWS FROM FARM
Authors: Belić Branislava , Cincović Marko R.
Published: June 2020

The aim of this study was to determine the threshold value and clinical significance of neutrophils to lymphocytes ratio in cooling the cows in lactation that follows. In routine hematological examination of 114 cows 7-15 days after parturition, the number of neutrophils and lymphocytes and neutrophil to lymphocyte ratio was examined. The marginal value of N: L correlation that best separates the cows that will be cooled from those that will remain in production in the lactation that follows is 1.05. If the N: L ratio at this level is more than 90% probability (specificity 90.32), it can be claimed that the cows will later be cooled from production. If the value of N: L correlation is about 0.65 with 90% confidence it can be assumed that the cows will remain in the herd (sensitivity 90.92). The area under the ROC curve was 0.751, which confirms a significant association between the values of N:L correlation after parturition and cooling the cows from the farm (p ~ 0.01). 72% of cows with the value N:L >1.05 were cooled from production for 12 months, versus 20% of excluded cows with N:L <0.5. The neutrophils to lymphocytes ratio in early lactation is a useful indicator for assessing the risk of cooling the cows from production.

Published: June 2020

The paper presents the recent finding of resistance phenotype and distribution of resistant genes in Escherichia Coli (E. coli) isolated from wild life. The resistance distribution was depended on animal species, their natural habitat, and some seasonal variations were also evident. Wild animals residing close to the farms were more often spreaders of resistant bacteria than those found in nature. It was shown that humans have an important role in appearance and dissemination of resistant E. coli in population of wild animals.

One of the main directions in the system of prophylaxis and fight against tuberculosis of animals belongs to the disinfection. For each disinfectant, it is important to have the following: good solubility in water, to own the wide spectrum of antimicrobial action, not to reduce antimicrobial activity in the presence of organic matters and hard water, not to be toxic or low-toxic for people and animals, not to have an unpleasant smell, not to damage the decontaminated objects, to be proof at storage, accessible for transporting and application, and also economic when exposed in the environment. The purpose of the research was, to study a bactericidal action in new disinfectant, in relation to Mycobacterium. The first stage of study was on the bactericidal properties in potential disinfectant with atypical mycobacteria, type of M. fortuitum № 122. For this purpose preparations were done by following the “Javelle-Kleyd” and “Geksadekon” instructions. It was concluded that crop and biological methods have bactericidal activity in relation to Mycobacteria tuberculosis, bovine kind with disinfectants “Javelle-Kleyd” in concentration 0,1 % and exposure of 30 minutes and 1hour and “Geksadekon” in concentration 3 % and exposure time of 5 hours. “Javelle-kleyd” and “Geksadekon” disinfectants in certain modes, are possible to apply for prophylactic and forced disinfection in happy and unhappy economies in relation to tuberculosis of animals.

The color, aroma and fl avor are major sensory characteristics of honey, which are mainly determined by the botanical origin of honey as well as by processing and storage conditions. Increased moisture content above the maximum permitted level could result in honey spoilage, which aff ects its sensory properties. The higher water-in-honey content, the greater possibility of yeast fermentation and thus the change of the fl avor and color ofhoney. Fermentation process results in alcohol formation and, in the presence of oxygen, the alcohol will break down to acetic acid and water, which causes honey to have sour taste. Thus, moisture content of honey is a critical parameter for its quality as it aff ects the stability of honey and its resistance to microbial spoilage during storage. Physicochemical analysis of moisture content and acidity of honey play an important role in determining the overall characteristic of honey and final assessment of its quality. In this study, the investigation of aforementioned parameters resulted in positive quality assessment for 48 of 50 examined honey samples produced in 2013 in the territory of Vojvodina.
