Authors: Todorov Pavel G.
Published: June 2020

In this paper with the help of the analytic theory of the canonical cubic equation developed by us in [14]-[15] we verify in a new, simple and natural way the Sendov conjecture for the canonical cubic equation and find new results for the mutually location of its roots and the roots of its derivative equation in the whole complex plane.
L'astronomie égyptienne
Authors: Andrillat Henri
Published: June 2020

In Egypt, stars and planets were considered as gods and astronomy was practiced by priests in the temples. It was in an outburst of religious fervor that these priests-astronomers were observing the heavenly bodies, the motions of which perfectly measured the time of men.

Thus, the order of the universe was a temporal one and they obser¬ ved the sun to fix the hours of the day and the stars to fix the schedule of the night ritual. The latter were preferentially zodiacal stars, the 36 decans.

The first temporal cycle was that of the sun, which was Khepri, the sun appearing, in the morning, Râ, in the middle of the day, with all the power of its light and finally Atum, in the evening. A cycle similar to the fate of man.

But the most important time cycle of Egyptian astronomy was that of the heliacal rising of Sirius, the goddess Hathor, the Lady of Denderah, with a yearly period of exactly 365,25 days, during all the history of Ancient Egypt.

Thus, Egyptian astronomers built a calendar of 365 days, which was never corrected, and in which the heliac rising was evidently shifted at the rate of one day every four years. The year had twelve months of thirty days and a holy period of five days.

Egyptian priests had set up this calendar to set the dates of the religious feasts and observed stars to fix the hours of the night.

The orientation of the monuments, principally the pyramids, was also a task of Egyptian astronomy.

In the Ptolemaic epoch, the temple of Denderah was adorned by the great famous zodiac, presently in the Louvre Museum in Paris. It worked as an universal julian calendar, as well as for astrological ends.

On a class of parabolic equations with a nonlocal boundary condition
Authors: Bouziani Abdelfatah
Published: June 2020

The present paper is devoted to a proof of the existence, uniqueness and continuous dependence of a strong solution upon the data for a mixed problem which combines Neumann and integral conditions for a class of parabolic equations. The proof is based on an a priori estimate and on the density of the range of the linear operator associated to the abstract formulation of the studied problem.

De Ptolémée à Copernic : Science en évolution ou révolutions scientifiques
Authors: Pecker Jean-Claude
Published: June 2020

Après avoir défini ce que l'on peut entendre par «science », et par «révolution», on parcourt les allers et retours de l'histoire des sciences du ciel, ceux, concomitants, de l'histoire des concepts religieux en matière d'univers astronomique. Il est montré que la science travaille sur l'acquis, le développe, le transforme, en étend les limites. Mais elle ne consiste pas en des bouleversements impliquant de brutales et complètes remises en question. En revanche, la «théorie des révolutions scientifiques », par son influence sur certains milieux non scientifiques, voire sur le grand public, comporte des dangers pour la société, celle de lui faire prendre des pseudo-sciences pour de véritables sciences, et d'en faire la victime de cette erreur de jugement.

Published: June 2020

We find sharp explicit estimates for the modulus and the argument of the totally monotonie functions.

Let T denote the class of totally monotonie functions [formula] where [formula]

and μ(t) is a probability measure on [0, 1]. The class T was introduced by Hausdorff [1] and studied by Wirths [2] and others. Sharp estimates for ƒ (z) | in implicit forms were proved by Wirths [2, p. 512, Corollary 2.1]. Now we will obtain sharp explicit estimates for I ƒ (z) | in another way. In addition, we find sharp estimates for arg (ƒ(z)/z), where "arg" everywhere is in the internal (-π, π].

Single Subdynamics for potential scattering
Authors: De Haan Michel , George Claude D.
Published: June 2020

A subdynamics theory has been presented recently in which quan¬ tities characteristic of an irreversible behaviour, such as that of a collision process, appear in the generator of evolution. The original dynamics, with degrees of freedom in large number, is first widened once self-energy parts have been recognized. The redundancies are then constrained by the requirement that the evolution takes place entirely in a subdynamics associated with a vacuum defined by reference to the observational situation of interest. This scheme, resulting in no loss of physical information, is examined in detail in the simple case of potential scattering, after that incoming, outgoing and intermediate degrees of freedom are distinguished. The relation with previous approaches is analysed.
From the astronomical theory of paleo-climates to global warming
Authors: Berger André
Published: June 2020

The future of our climate is a primary concern not only at the human time scale but also at the geological time scale. At both time scales, modeling the climate system, estimating the climatic sensitivity from past climates or researching best analogs in the past are the most usual tools to predict what might be the future climate. Most of the time, paleoclimatologists feel that the last interglacial is a good candidate for our future warm climate. They study its stability and length that they compare to our pre¬ sent interglacial. Limitations to such procedures have been stressed. In particular, a special attention must be care to the forcings of past climates (both insolation and C02, in particu¬ lar) because they are important factors which shape the complex latitudinal distribution and seasonal cycle of the world climates. At least from the astronomical point of view the Eemian is not a good choice for the future of the Holocene. Better candidates would be around 400,000 YBP (isotopic stage 11) and even better around 2,000,000 YBP where interglacials lasted longer than during the middle Pleistocene. But first of all, it must be stressed that the orbital forcing for the present and next tens of thousands of years is almost unique, that the predicted C02 con- centration for the next centuries (and already the present ones) are unprecedented and finally that, according to our modeling results, the present Holocene interglacial will, most probably, last exceptionally long, with no counterpart over the last million years. Such a long duration is a very robust feature in our numerical experiments. It seems to be related to the pretty high value of CO 2 which lasts already since 10 kyr BP compensating for the declining astronomical forcing. In addition, our results show not only that the Holocene might last particularly long, but also that the sensitivity of our climate system to the green¬ house gas forcing might be exacerbated. As a consequence, there is a threshold in the greenhouse gas concentration of about 700 ppmv beyond which the Greenland ice sheet melts in about 5000 years and does not recover before a few tens of thousands of years. Such results reinforce the need of limiting the greenhouse gas emissions from human activities as soon as possible. In Bel¬ gium, in particular, one way of doing it efficiently is without any doubt by increasing the share of our electricity production from the nuclear sector. Scenarios for the next decades show clearly that this is unavoidable if Belgium is willing to meet its Kyoto target.
Dust storms in the Middle East.
Authors: Goudie Andrew Shaw , Middleton Nicholas J.
Published: June 2020

Dust storms are widespread in the Middle East and their gen¬ eral distribution is known from climatic data from ground mete¬ orological stations. However, the Total Ozone Mapping Spec¬ trometer (TOMS) enables a more perfect picture to be gained for those many areas where meteorological data are sparse. TOMS analysis permits the seasonal pattern of dust storm activ¬ ity, the spatial pattern of dust storm activity and the passage of major dust events to be plotted. The summer months are the time of greatest dust storm activity, and the borderland between Oman and Saudi Arabia seems to have the greatest level of dust activity in the area. From time to time major dust-producing sys¬ tems cross from the northern Sahara and from the Red Sea region into Arabia. For reasons that are not clear, the Kuwait-southern Iraq area does not appear to be such a significant dust source region as the meteorological data would suggest.

Équations à retard et leurs applications
Authors: Erneux Thomas
Published: June 2020

Les équations différentielles à retard tiennent compte de l'effet du passé dans la prédiction du futur. Elles sont apparues dans différentes disci¬ plines scientifiques mais ce n'est que récemment que nous pouvons les étudier. Le retard est le temps du contrôle pour les systèmes méca¬ niques, le temps de gestation en biologie, le temps de réaction en conduite automobile. Le retard conduit à des instabilités dynamiques et est responsable de bifurcations vers des oscillations entretenues. Ces bifurcations sont étudiées pour une série de problèmes.
Estimates for L vector fields with a second order condition

An estimate on the integral of the product of a vector field ƒ e L1 (RN ; R2N~]) and a function u e W1,Af(RjV) when ƒ satisfies a condi¬ tion involving the sum of some second-order derivatives. This gener¬ alizes a previous result concerning vector fields whose divergence is a summable function [1, 3]. A relationship between this inequality and a Korn-Sobolev inequality of Strauss [2] is established.
What is the meaning of the wave function ?

On the characteristic exponents of Floquet solutions to the Mathieu equation
Authors: Sträng Jan-Eric
Published: June 2020

We study the Floquet solutions of the Mathieu equation. In order to find an explicit relation between the characteristic exponents and their corresponding eigenvalues of the Mathieu operator, we consider the Whittaker-Hill formula. This gives an explicit relation between the eigenvalue and its characteristic exponent. The equation is explicit up to a determinant of an infinite dimensional matrix. We find a third-order linear recursion for which this determinant is exactly the limit. An explicit solution for third-order linear recursions is obtained which enables us to write the determinant explicitly.
Pergélisol et réchauffement climatique : la glace du sol, le CO2 des sols arctiques et les hydrates de méthane
Authors: Pissart Albert
Published: June 2020

L'Arctique est la région où le réchauffement climatique est et sera le plus important de toute la terre. Ce réchauffement se produit et se produira principalement pendant l'hiver. Trois conséquences de ce réchauffement sont considérées : 1) La fusion de la glace du sol qui sera extrêmement dommageable pour les infrastructures. Elle se produira d'abord à la bordure méridionale du pergélisol à la suite du réchauffement de l'hiver et partout dans l'Arctique si les températures d'été s'élèvent. L'homme ne pourra pas empêcher la fusion de cette glace souterraine. 2) Il est possible que le réchauffement des sols entraîne la décomposition de l'humus accumulé en grande quantité depuis des millénaires dans les sols arctiques. Cela augmenterait considérablement l'effet de serre. 3) Un dégagement de méthane accumulé dans les hydrates se trouvant dans le pergélisol et sous les fonds marins pourrait se produire. Le danger est évident à long terme mais, dans l'état des connaissances, il est malaisé d'estimer les risques à court terme. Le méthane provenant des hydrates sera exploité de manière commerciale avant une décennie.
Synergetics and (or) plate tectonics
Authors: Goryainov Pavel M. , Ivanyuk G. Yu. , Kalashnikov A. O.
Published: June 2020

Today geology aspires to be in general agreement with the progress of modern natural science. But it can become a cause of crisis of some geological directions. Last decade many researchers were trying to bring geological postulates in accord with synergetics ideas, first of all principles of plate tectonics. We've elected the plate tectonics only because it, in accordance with current belief, focuses many problems and achievements of modern geology and pretends to be a standard of research success.

Here it is demonstrated one of general property of lithosphère dynamic processes -cooperativity and, thus, long-range order, -by the example of canonical structures (folds, lenses, fracture networks). A thermo-gravitational instability effect (Bernard's effect) is a model of these processes. Now it is known some attempts to correlate this phenomenon with plate tectonics foundations. But our researches have shown that fundamental tenets of the plate tectonics (such as independent continental drift, two-cell convection, multi-layer convection etc.) are superfluous from synergetic point of view.

Analyse moléculaire du comportement des racines
Authors: Masson Patrick , Harrison Benjamin R. , Stanga John , Neal Carolyn , Vaughn Laura , Jia Gengxiang , Larson-Rabin Zachary
Published: June 2020

L'évolution a doté les plantes d'une capacité assez remarquable d'utilisation de paramètres directionnels de leur environnement pour diriger la croissance de leurs organes. Cette flexibilité conditionne leur survie dans des environnements parfois très variables, et contribue à leur compétitivité et capacité reproductive. Malheureusement, notre compréhension des mécanismes responsables de ce comportement reste très limitée. Nous avons concentré nos recherches à l'étude des mécanismes qui permettent aux racines d'utiliser des paramètres mécaniques de leur environnement (gravité et obstacles) pour guider leur croissance. Dans cet article, nous discutons les mécanismes qui permettent aux racines de détecter leur orientation par rapport au vecteur de la gravité, et de diriger leur croissance en fonction de cette information (gravitro-pisme). Cette analyse permet l'identification de molécules qui contribuent au contrôle général de la polarité cellulaire chez les plantes, avec des implications assez remarquables pour notre compréhension des mécanismes qui contrôlent le développement et la morphogenèse des plantes.

Published: June 2020

Introduction: Cardiovascular diseases (CVDs) take the lives of 17.9 million people every year, 31% of all global deaths. Most patients with CVDs can be diagnosed, treated and managed by health-care practitioners at the primary health care system. Strengthening CVDs patients management and continuity of care in Commune health centres (CHCs) play an important, sustainable and cost-effective solutions.

Objectives: To describe the current situation of CVDs management at commune health centers in Thua Thien Hue province.

Methods: A cross-sectional study was conducted in the total 152 CHCs in Thua Thien Hue province. Service availability and readiness assessment (SARA-WHO) instrument was used to assess CVDs management of CHCs.

Results: CVDs diagnosis and/or treatment were available at 97.4% of CHCs surveyed. Most CHCs were fully builted in equipments for screening and early detection of CVDs (>99%). Most CHCs delivered prevention services regarding risk factors of CVDs. More than 85% of CHCs weren’t equipped with adequate medicines for CVDs management prescribed by the Ministry of Health. Calcium channel blockers (90,8%) and angiotensin converting enzyme inhibitor (77%) were offered at the CHCs.

Conclusion: CVDs prevention and management services at grassroots level have been fully and widely deployed throughout the province. It’s strongly recommended to enhance the availability of medication for CVDs, especially in mountainous area. The service readiness indicator of CVDs management in Thua Thien Hue Province is 67.9 points.

Published: June 2020

La enfermedad celíaca (EC) es un trastorno inflamatorio crónico causado por una respuesta inmune anormal inducida por una intolerancia permanente al trigo, la cebada y el centeno en la dieta. Dicho diagnostico se realiza por medio de pruebas sanguíneas de tamizaje en conjunto con confirmación endoscópica y biopsia. La EC se ha asociado a otras enfermedades autoinmunes y manifestaciones sistémicas. En los últimos años se ha estudiado con mayor relevancia la relación de EC con la infertilidad no explicada, dentro de los mecanismos fisiopatológicos se destaca la deficiencia nutricional y procesos autoinmunes especificos ya sea en el momento de la concepción o que estos mecanismos se desarrollen previo provocando deficiencia ovárica. Se ha propuesto realizar el tamizaje de EC en pacientes infertiles, sin embargo ha generado controversia debido a su utilidad. Si bien es cierto la relación entre dichas patologías es fuerte, se ha demostrado en los diferentes estudios que la utillidad en realizar dicho tamizaje de rutina depende del tipo de población y su prevalencia

Para avanzar en el mejoramiento para tolerancia al estrés hídrico en maíz (Zea mays L.) es necesario acumular información de loci de caracteres cuantitativos (QTLs) asociados con este carácter en líneas elite adaptadas a condiciones de sequía que puedan emplearse para los escenarios de cambio climático. En este estudio se evaluaron en los ambientes de sequía y riego un grupo de líneas dobles haploides derivadas de la cruza LPSC7F64 × CML495 y un grupo de cruzas de prueba hacia la línea CML494. Los resultados indicaron que en las dos condiciones de humedad, el índice de vegetación diferencial normalizado (NDVI) fue el parámetro más asociado con el rendimiento (rg > 0.85), al igual que el índice que combina el vigor temprano, vigor final y la senescencia (COMBO; rg > 0.68). Se identificaron QTLs para vigor temprano bajo condiciones de sequía (Bin 1.03) que explican el 10.9 % de la variación fenotípica (% VF) (aditividad + 26), al igual que COMBO bajo sequía (Bin 1.02/1.03) con el 7.49 % VF (aditividad + 28). Así mismo, se ubicaron varios QTLs para sequía y riego (Bin 4.05), donde sobresalieron COMBO_LR (13 % VF) y área bajo la curva de la senescencia (AUCSEN) (13.81 % VF); además, se identificaron otros QTLs de COMBO_LR en la Bin 5.05 (11.6 % VF) y COMBO_LR en la Bin 7.03 (9.9 % VF). Adicionalmente, se localizaron QTLs para rendimiento (aditividad 0.12 t ha-1). Estos QTLs pueden ser útiles para mejorar el rendimiento del maíz bajo condiciones de sequía y riego.

Zoonotic desease transmission can happen in every stage of animal-orign food production, from farm to table. This study is counducted to evaluate the understanding of farmers and animal-origin food product enterprises about zoonotic diseases and their prevention in Kupang City. The study was conducted 6 region with 200 respondents from farmers, 30 respondents from buthcers, 30 respondents from meat distributors, 30 respndents from meat seller and 30 respondents from food industry. The result than analyzed by descriptive analysis and than presented in graphics and tables. The result shows that the understanding of farmers and animal origin food product enterprise in Kupang City about zoonotic diseases is low so that their behavior, in attempt to prevent zoonoses, is not maximal. In farmers, 87,5% of farmers do not have a proper check up for their animal’s health and 30,5% of them still consume meat from sick and dead animals. In butchers, 80% of butchers do not have a hand-washing facility, 86,7% do not have a seperated room for meat and visceral handling, 96,7% do not use a proper foot-wear when working, and 43,3% of them stil use water from the river or from gutters. In meat distributors, 90% of them only use bike as vehicle for the distribution. In meat sellers, 96,7% of meat sellers allow their customer to directly touch the product, 80% do not have a hand-whashing facility and 100% of them do not have a refrigerator as a storaging vacility. In food industry, 90% of them have a good cleaning behavior, wash their hand with flowing water and soap, and have a refrigerator as storaging vacility. It can be conlcuded that food industry is the only stage with good behavior in atempt to prevent zoonotic desease transmission.
First checklist of lichens and lichenicolous fungi from Mauritius, with phylogenetic analyses and description of new taxa
Authors: Diederich Paul , Ertz Damien
Published: June 2020

A first checklist of the lichens and lichenicolous fungi from the Republic of Mauritius is presented. It is based on older literature reports and on collections made by the authors, mainly in 2016, from the isles of Mauritius and Rodrigues. A total of 216 species are accepted, either as relevant specimens have recently been critically studied or revised by lichen taxonomists, or as we have collected and identified such material ourselves. A further 226 taxa have been reported from Mauritius but are not accepted here, either as no relevant herbarium material has recently been examined, or as previous records are dubious or erroneous; 111 taxa have been newly described from Mauritius in the past, plus 12 of which the Mauritian origin is dubious. Here we report 56 taxa as new for the island of Mauritius, and we describe two new genera (Baidera, Serusiauxia) and eight new species (Baidera mauritiana, Biatoropsis millanesiana, Chapsa alletii, Collemopsidium mauritiae, Nyungwea pyneei, Porina florensii, Pyrenula muriciliata, Serusiauxia inexpectata). Two new combinations are proposed: Loekoesia apostatica (≡ Lecanora apostatica) and Sticta flavireagens (≡ Stictina flavireagens). Phylogenetic analyses are presented for species of Arthoniales, Biatoropsis, Porinaceae, Pyrenulaceae and Teloschistales.

Published: June 2020

Our knowledge of the diversity of African freshwater red algae is rather limited. Only a few reports exist. During our field work in the last five years we frequently encountered freshwater red algae in streams in Rwanda and Madagascar. Here we describe four new species and one new genus of freshwater red algae from the Batrachospermales, based on morphological and molecular evidence: Kumanoa comperei from the Democratic Republic of the Congo and Rwanda is related to K. montagnei and K. nodiflora; Kumanoa rwandensis from Rwanda is related to K. ambigua and K. gudjewga; Sirodotia masoalensis is related to S. huillensis and S. delicatula; and the new genus and species Ahidranoa madagascariensis from Madagascar is sister to Sirodotia, Lemanea, Batrachospermum s.str. and Tuomeya. There is also evidence for the presence of Sheathia, which was recorded as yet-unidentifiable Chantransia stages. These are among the first new descriptions since 1899 from the African continent and since 1964 from Madagascar. A short history of the exploration of freshwater red algae from Africa and Madagascar is provided. All new taxa are accompanied by illustrations and observations on their ecology.

The number of computers connecting to the internet is getting increased day by day, while the number of computers connected is increasing then it is obvious that the amount of network-based attacks will also increase. In this way, we use a honeypot that is a framework trap that is set to act against unapproved utilization of PCs and data frameworks. Around the globe, a huge number of individuals get to the web each day, honeypot which can likewise be called Intrusion Detection Technology is another time of security innovation that screens device to avoid malicious sports. The whole factor of this research paper is an Intrusion Detection System and Intrusion Prevention System, elements accomplished via honeypot and honeytrap methodologies. A great deal of research went into this review paper and the discoveries propose that the honeypots are drawing in light of a legitimate concern for analysts as a significant security system that can be actualized to stop or occupy the assaults the system assaults and give a chance to find out increasingly more about the source and nature of these assaults. Hence we can say that a honeypot can be utilized as an examination apparatus to accumulate increasingly more data about the expanding number of system assaults that are going on consistently.
No-madres: mercado laboral y reproducción
Authors: Alvarez Bruna
Published: June 2020

Desde los años 80 –y paralelamente al proceso de desregularización del mercado laboral español (Espin-Andersen, 2000)–, se ha producido un aumento de la actividad laboral de las mujeres y las madres (Tobío, 2005; 2012), pero en unas condiciones de desigualdad con los hombres y los padres. Para las mujeres, a menor número de hijos/as, mayor probabilidad de encontrar un empleo remunerado (Moreno, 2012), y más posibilidad de obtener un salario más alto –en 2009 las mujeres con hijos/as reducían su sueldo un 6% si tiene un hijo/a, un 14% si tiene dos, y más de un 15% si tiene tres– (Molina y Montunga, 2009). Según la encuesta de fecundidad realizada por el INE (2018), tres de cuatro mujeres desearían tener más hijos de los que tienen, de las cuales un 25,05% dice que no los ha tenido por motivos laborales, y un 19,10% por motivos económicos, produciéndose un child gap (Bernardi, 2003) entre los hijos deseados y los que finalmente se tienen. A través del análisis de un blog de madres y 59 entrevistas a madres trabajadoras, se concluye que el mercado laboral español funcionaría como un mecanismo de gobernanza reproductiva (Morgan y Roberts, 2012), definiendo a “las madres” como malas trabajadoras, ya que se considera que son las principales cuidadoras de sus hijos/as, independientemente si lo son o no, y por lo tanto se entiende que no podrán cumplir con las demandas de tiempo y presencia que requiere el mercado laboral español. El mercado laboral prioriza las “no-madres”, definidas como personas a quien no se les atribuye que puedan priorizar los cuidados de los hijos/as a las demandas laborales, es decir hombres y mujeres, estas últimas sin hijos/as y que no estén en edad potencial de reproducirse.
The Mandatory Handshake in Danish Naturalisation Procedures: A Critical Race Studies Perspective
Authors: Seemann Anika
Published: June 2020

This article examines the recent introduction of a mandatory handshake in Danish naturalisation procedures from the perspectives of ‘racism’ and ‘race discrimination’. Drawing upon Critical Race Theory, it employs a discursive, deconstructive and contextual analysis to uncover the racist underpinnings and effects of the handshake requirement. The article is divided into two main parts. Part I demonstrates why the handshake requirement needs to be understood as racism. The analysis focuses on three aspects of the handshake requirement: 1) the ‘racializing narratives’ drawn upon in the legislative process; 2) the motivations behind the legislation; and 3) the ways in which the handshake requirement manifests as racism in society. Part II assesses the relevance of this finding from the perspective of anti-discrimination law. It examines the discriminatory nature of the handshake, before discussing some of the shortcomings of current international and European law in relation to race discrimination. The article closes by discussing the importance of developing a more ‘race-aware’ approach to the law in European legal scholarship.
