Remote communication for people with disabilities: Support persons’ views on benefits, challenges, and suggestions for technology development
Authors: Buchholz Margret , Holmgren Kristina , Ferm Ulrika 
Published: June 2020

BACKGROUND: Being able to communicate through digital channels is a prerequisite for participation in contemporary society. People with communicative and cognitive disabilities (CCDs) face challenges in this area, thus often being excluded from participating fully in society. OBJECTIVE: This qualitative study focuses on aspects of technology that facilitate or impede remote communication in people with CCDs. METHODS: Support persons for people with CCDs ([Formula: see text] 21) participated in five focus groups to discuss this topic. RESULTS: Data analysis yielded two themes: using standard technology and using assistive technology. Each theme encompasses categories describing aspects and functions of technology that facilitated or impeded remote communication. The support persons felt that standard and assistive technology needed possibilities for personalization for ease and accessibility. There is a need for increased compatibility between assistive and standard technology and between platforms. Remote communication technology must be made more accessible and easier to use for both people with CCDs and those in their networks. CONCLUSIONS: The study provides an overview and illustrative examples of how technology can enhance or hinder remote communication. We offer suggestions on how technology can be developed to meet the specific needs of people with CCDs and simplify remote communication for them.

Published: June 2020

A amoreira-preta é uma espécie rústica e, apesar de ter sido introduzida no Brasil na década de 70, poucos trabalhos relacionados ao manejo fitotécnico foram realizados. Objetivou-se com a presente pesquisa avaliar o efeito vegetativo e produtivo em amoreira-preta, do uso de diferentes doses de torta de mamona como adubação de pré-plantio. O experimento a campo foi implantado em área experimental da Embrapa Clima Temperado, Pelotas, RS e, as análises químicas, no Laboratório de Nutrição Vegetal da mesma instituição, no período de 2008 a 2012. Os tratamentos foram: T1- 0; T2- 200; T3- 400; T4- 800; T5- 1.600g de torta de mamona por planta, aplicados no momento da implantação do pomar.O delineamento experimental foi em blocos ao acaso. Avaliou-se a massa seca de poda de formação, o número de hastes, o comprimento das hastes, a massa seca de poda de produção, a produção, o número médio de frutas por planta, a massa média de frutas, o diâmetro das frutas e o conteúdo de sólidos solúveis. Em 2010 foi realizada análise do teor de nutrientes nas folhas, determinando-se os seguintes elementos: N, P, K, Ca, Mg, Fe, Mn, Zn e Cu. As variáveis avaliadas não foram influenciadas pelas doses de torta de mamona. Não foram verificados efeitos residuais de longo prazo sobre o desenvolvimento vegetativo, produtivo e dos macro e micronutrientes da amoreira-preta Tupy. Neste sentido, conclui-se que o uso de torta de mamona não causa efeito no comportamento da planta de amoreira-preta nas condições do presente trabalho.
Correlation Analysis Between Yield Component Traits and Yield of Watermelon Genotypes (Citrullus lanatus)
Authors: Mulyani Prinsip Trisna , Waluyo Budi 
Published: June 2020

Watermelon [Citrullus lanatus (Thunberg) Matsum & Nakai] is a plant that is widely cultivated and contains important nutritional compounds such as citrulline, arginine, and glutathione. In the last few years, the consumption of vegetables and fruits in Indonesia has tended to increase but cannot be fulfilled by domestic production. Yields are influenced by the character of yield components. This research aims to study the relationship between yield component traits and yield of watermelon. The study was arranged in augmented design and planting material are 75 watermelons genotypes and 3 checks varieties. The results showed that there are some characters of yield components that correlated with yields. The characters of yield components that have positive genetic correlation and positive phenotype correlation with fruit weight are stem length, number of branches, fruit stalk length, fruit length, fruit diameter, thickness of pericarp, number of seeds per plant, and weight of seeds per plant. The yield components characters that have a negative genetic correlation with fruit weight are day to flowering. The characters of yield components that have positive genetic and phenotype correlation with seed weight per plant are fruit weight, stem length, fruit length, fruit diameter, number of seeds per plant, seed length, and seed width. The Characters of yield components that have a negative genetic correlation with seed weight are day to flowering and the first female flower emerges. The characters of yield components that correlate with the yield are used as selection markers for indirect selection.
Cultural Diversity, Ethnocentrism and Terrorism in Mukoma WA Ngugi’s Black Star Nairobi (2013)
Authors: Babacar Diakhaté  
Published: June 2020

This article brings to light the obstacles that impede countries like Kenya to develop. In Black Star Nairobi, Mukoma WA Ngugi addresses cultural diversity issues and ethnic crisis. Like other African writers such as Chinua Achebe, Ngugi WA Thiong’o, Chimamanda Ngozi Adichie, Mukoma WA Ngugi displays to what extent Kenyans are tied to their cultures, traditions and ethnics. He demonstrates how ethnocentrism can have an impact on the socio-political activities of his people. He also pinpoints the drawbacks engendered by ethnocentrism like radicalization, terrorism and illegal immigration.

ACTUAL PROBLEMS OF URBAN LAND USE ON THE EXAMPLE OF KRASNOYARSK
Authors: Badmaeva S. , Maksimov E. 
Published: June 2020

In the modern world, in using land resources, we are faced with a number of problems, this is more expressed in megacities, because the majority of the population of our planet lives in these territories.
The article briefly analyzes the current state of Krasnoyarsk, physical-geographical and economic conditions of the city development. The issues of territorial planning in the city are considered on the example of the microdistrict "Pokrovsky". High-rise buildings and their crowding influenced on the formation of wind flows and dispersion of impurities. It is established that the building affects the wind speed, reducing it by nearly 25-30% compared to the undeveloped urban part. In a dense building, the wind speed can be reduced to 70%. Inefficient land use model is reflected in the quality of the living environment, including the connectivity of the territory. The infrastructure is developed for children of younger preschool age-yard areas are everywhere equipped with children's game elements. Social adaptability for the elderly in the district is poorly expressed. The issue of parking spaces is acute, and their lack indicates the impossibility of creating a neighborhood with a high level of quality of life. Local problems include the construction of noise screens along major highways, which have a low-quality design and technical solution. The provision of public transport is unsatisfactory. Spatially in the "intercession" we need a clear separation of yards and public spaces. Due to this, within the four large neighborhoods-quarters there will be a quasi-quarterly structure that helps to organize the hierarchy of spaces, eliminating or minimizing transit traffic through the yards.
De l'hexagone à l'hélice ou stéréochimie, hier et aujourd'hui
Authors: Bruylants Albert 
Published: June 2020

En chimie, la « structure » ou «constitution », c'est le mode d'enchaînement des atomes dans la molécule. L'importance de cette question décisive dans l'étude des composés chimiques a été reconnue, il y a plus de cent ans maintenant.
Pour en illustrer les développements, l'auteur a choisi de brosser cinq tableaux. Le premier se rapporte aux travaux sur la constitution des corps aromatiques qui ont conduit son auteur, l'Allemand Kekulé, alors professeur de chimie générale à l'Université de Gand, à imaginer comme structure du benzène un hexagone régulier dont chaque sommet est occupé par un atome de carbone et un atome d'hydrogène (1865).
Le deuxième est relatif à la parution à Rotterdam en 1875 du fameux ouvrage de van 't Hoff « La chimie dans l'espace » qui inaugura l'ère de ce qu'on a appelé depuis la stéréochimie, et dans lequel se trouve décrite la configuration, c'est-à-dire la « structure spatiale » des molécules, aux dépens du modèle d'atome de carbone tétraédrique.
Le troisième tableau situe la scène à Bruxelles au « Quatrième Conseil de Chimie Solvay » tenu en juin 1931 et traitant du sujet « Constitution et configuration des molécules organiques ». Les travaux de ce Conseil avaient contribué notamment à mettre en pleine lumière l'importance de la « dissymétrie moléculaire », au point de vue de l'activité optique des molécules.
Le quatrième tableau est consacré au problème de la conformation. La conformation, c'est la forme particulière que peut prendre une chaîne ou un cycle hydrocarboné par rotation des atomes autour de leur axe commun et l'« Analyse conformationnelle » est l'étude quantitative de la conformation moléculaire. L'intérêt de cette analyse, reconnu depuis une vingtaine d'années seulement, a été souligné par le symposium organisé par la Société Chimique de Belgique, en septembre 1969. Peu après, le Prix Nobel de Chimie était décerné à deux pionniers de cette question, le Norvégien Hassel et l'Anglais Barton. Le dernier tableau décrit quelques traits caractéristiques de la stéréochimie des composés macromoléculaires naturels. L'auteur a évoqué à ce sujet la structure des protéines en choisissant deux exemples du plus haut intérêt au point de vue biologique : celui de l'« hélice » ou conformation hélicoïdale attribuée aux polypeptides par Pauling et Corey et celui de la « double hélice » que Crick et Watson ont proposé pour l'acide désoxyribonucléique, ce dernier étant la substance présente dans les noyaux cellulaires et responsable des caractères héréditaires.
Il est fait état de l'éminente contribution des savants belges à ces questions d'importance capitale pour la chimie moderne ; deux lettres inédites de Van 't Hoff, datant de 1875 sont publiées.
Application de la méthode matricielle — harmonique à l'intégration des équations différentielles linéaires d'ordre quelconque à coefficients périodiques
Authors: Mangeron Démètre J. , Oguztöreli Mehmet N. , Iasjulionis A. I. 
Published: June 2020

Dans une série de ses travaux antérieurs, ayant pour but l'élaboration de différentes méthodes mathématiques aptes pour l'adaptation à l'usage des machines électroniques digitales de calcul, les auteurs ont élaboré la méthode matricielle-tensorielle, qui a été appliquée par eux-mêmes et ensuite par de nombreux auteurs surtout à la résolution des problèmes concernant l'analyse et la synthèse-cinématique et dynamique des mécanismes et des machines.
Dans ce travail les auteurs exposent des algorithmes pertinents aux opérations sur les séries trigonométriques qui constituent le fondement de la méthode matricielle-harmonique. Tout en renonçant d'exposer ici nombre d'applications concernant la théorie des mécanismes et des machines, les résultats acquis sont utilisés à l'intégration des équations différentielles linéaires d'ordre quelconque à coefficients périodiques.
Quelques questions relatives aux ensembles boreliens convexes dans les espaces polonais linéaires
Authors: Haezendonck Jean 
Published: June 2020

L. Dubins et D. Friedman [1] ont analysé le problème de l'enveloppe convexe d'un ensemble borelien dans l'espace ℝn Nous nous proposons de résoudre ici un problème inverse : étant donnés un ensemble borelien B et un ensemble convexe C dans un espace polonais linéaire et tel que C ⊂ B, est-il possible de trouver un ensemble borelien convexe C' vérifiant C ⊂ C' ⊂ B ?
Nous démontrons que cette proposition est vraie dans l'espace ℝ², mais qu'elle cesse de l'être en général dans les espaces ℝn pour n > 2. Ceci répond à une question de J. Feldman. Ensuite nous démontrons que dans des espaces polonais linéaires suffisamment généraux la projection d'un ensemble borelien et convexe suivant une direction sur un sous-espace polonais est un ensemble borelien.

Published: June 2020

In order to describe very accurately the reaction scheme of the acidic hydrolysis of amides (B) it is necessary to determine the value of the acidity constant (pKBH+) of the conjugated amidonium ion.
Connected with previous investigations in this area, following groups were examined along this line : a first one, R— CO— NH— C6H5— Y involving two different series (R = CH3— and C2H5— ) and for each one, Y = CH30-, CHS-, H— , Cl-, CH3CO-, N02-. A second one pertains to X— C6H4— CO— NH— C6H4— Y and is developed along five different series varying X (X = CH30— , CH3— , H— , Cl—, N02— ) and Y (Y = CH30-, CH3-, H-, Cl-, N02-).
Acidity functions, H0 and HA were used for that purpose and new values of were determined for anilides.

Authors: Hemptinne Marc de , Fayt A. , Van Riet R. 
Published: June 2020

Le travail met en évidence l'effet d'un laser C02 sur le spectre d'absorption de ce même gaz dans la région de 15 fi. On étudie plus spécialement le comportement des raies d'absorption sous l'effet d'un rayonnement laser régulièrement interrompu. Eu égard aux variations de population des états excités, on explique de manière satisfaisante les variations d'intensité de l'absorption en fonction des temps d'irradiation.
L'action du laser sur le spectre d'absorption d'un mélange de C02 et de gaz non absorbants apparaît comme une fonction de la conductibilité thermique du mélange.
Contribution à la pondération des points d'observation
Authors: Debehogne Henri 
Published: June 2020

In the plate reduction, when a polynomial transformation is used, the minimum of the effect of an error calculated at the point where the error is acting does not always coincide with the plate centre (Debehogne, 1972). We have proved this property by means of a network (fictitious stars). Here, we will present a theoretical demonstration for the first and second order (straight line and parabole).
For the first order, the minimum coïncides with the reference points centre (table I).
For the second order, the minimum coïncides with this centre only when B = [formule], where n is the number of reference points, xt the abcisses, [xt2] = [formule]
i
Moreover, there are two maxima symetrically displayed around the centre for n < B. When B < n < 3 B,
we have a maximum at the centre and two minima.
See this extrema values in table II.

where pFQ[z] denotes a generalized hypergeometric function, the authors give here a general integral representation in terms of a third member of the class and discuss its numerous interesting special cases including results proved recently in the theory of certain classical polynomials.
Coefficient alpha, poids sec en surplus, allométrie et croissance des végétaux
Authors: Ledent Jean-François 
Published: June 2020

Coefficient alpha , surplus weight, allometry and plant growth.
A detailed discussion of the biological and mathematical considerations leading to the definitions of growth parameters such as coefficient alpha and surplus weight is presented.
The study of relationships between leaf area and total dry weight with these parameters appears to have little chance to be meaningful for the understanding of plant growth and for grain yield prediction. The basic hypotheses in the theory leading to the introduction of these parameters are unconvinicing. There are gaps and inconsistencies in the theoretical developments leading to the concept of surplus weight. A knowledge of the values taken by alpha is only secondary for the calculation of surplus weight. Several computational and mathematical difficulties may result in making observed values of these two parameters unlikely to have any physiological meaning.
Espaces pseudo-riemanniens homogènes à quatre dimensions
Authors: Sengier-Diels J. 
Published: June 2020

Nous construisons les métriques pseudo-riemanniennes admettant au moins un groupe d'isométries de dimension quatre en considérant les espaces simplement connexes pour lesquels l'isotropie est discrète. Il existe alors sur l'espace un groupe d'isométries simplement transitif et l'espace est isométrique à un groupe de Lie sur lequel est définie une forme quadratique invariante par les translations à gauche.
Dans un article ultérieur nous étudierons les propriétés physiques de certains de ces espaces.
La vocation de la biophysique
Authors: Duchesne Jules 
Published: June 2020

The author begins by discussing the two main fundamental methods, i.e. integrism and reductionism, which are used for the interpretation of the physical world.
But the main idea which dominates this paper is based on an analogy between Mendeleïev's periodic law which transcends inorganic matter, and the behaviour of living beings.
It is suggested that, just as atomic masses were used to classify the species in the inanimate world, it would be valuable to codify the organic world in terms of maximal life-spans.
A theory was recently worked out by the author to interpret this very general phenomenon on the basis of the concentrations of organic free radicals in the brain. This is strictly related to the presence of a more or less free electron, which itself explains the remarkable structure of the periodic system.
Further, suggestions are made concerning other fundamental properties of living matter, such as senescence and cancer, and these are integrated with life-span in a unifying theory.
It is mainly in these directions, based on a research of holistic properties of living matter, that a new way is opened up for the further evolution of biophysics itself.

Évolution, involution, sénescence et cancer
Authors: Duchesne Jules 
Published: June 2020

The paper develops and extends views expressed earlier by the author. The different new concepts concerning prebiotic and biotic evolution, as well as the extinction of species, are now interpreted by a single mechanism which is based on the variation, in both directions, of the molecular weight of DNA. Then, the meaning of the apparent passivity of a large percentage of this compound inside the nucleus is explained.
Following this, the phenomena of ageing of the individual and of cancer are integrated into the general behaviour of living matter and new types of therapy are inferred from this.
Théorie du champ pictural : Les facteurs spatiaux

Ce travail aboutit à paramétriser l'espace pictural. Il nomme les facteurs qui sont impliqués dans la perception de l'espace, définit la façon de les quantifier et fixe la méthode qui permet le calcul de leurs interactions.
La validité de cette méthode et son adéquation aux œuvres picturales ont été testées sur l'œuvre de Mondrian.
