Anion sensing properties of compound 1and its metal complexes (1-Zn,1-Ni and1-Cu) are tested in the presence of various anionic species in acetonitrile media. Fluorescence measurements indicated that, 1-Ni and1-Cu do not have any selectivity towards various anions except weak interactions.On the other hand1-Znshows good response and selectivity toward acetate ion based on fluorescence enhancement. In addition, JOB studies demonstrate that the interaction between 1-Znand acetate ion were with a ratio of 1:2 and limit of detection (LOD) of 1-Znwas calculated as 4.76x10-6M for acetate ion detection. Moreover, 1-Znprovides a certain change in color in the presence of acetate. The results demonstrate that 1-Zncan be utilized for fluorogenic and naked eye detection of acetate anion.
On One Sufficient Condition for the Irregularity of Languages
Authors: Belousov A. I. , Ismagilov R. S. 
Published: April 2019

The article deals with a proof of one sufficient condition for the irregularity of languages. This condition is related to the properties of certain relations on the set of natural numbers, namely relations possessing the property, referred to as strong separability. In turn, this property is related to the possibility of decomposition of an arithmetic vector space into a direct sum of subspaces. We specify languages in some finite alphabet through the properties of a vector that shows the number of occurrences of each letter of the alphabet in the language words and is called the word distribution vector in the word. The main result of the paper is the proof of the theorem according to which a language given in such a way that the vector of distribution of letters in each word of the language belongs to a strongly separable relation on the set of natural numbers is not regular. Such an approach to the proof of irregularity is based on the Myhill-Nerode theorem known in the theory of formal languages, according to which the necessary and sufficient condition for the regularity of a language consists in the finiteness of the index of some equivalence relation defined by the language.The article gives a definition of a strongly separable relation on the set of natural numbers and examines examples of such relations. Also describes a construction covering a considerably wide class of strongly separable relations and connected with decomposition of the even-dimensional vector space into a direct sum of subspaces of the same dimension. Gives the proof of the lemma to assert an availability of an infinite sequence of vectors, any two terms of which are pairwise disjoint, i.e. one belongs to some strongly separable relation, and the other does not. Based on this lemma, there is a proof of the main theorem on the irregularity of a language defined by a strongly separable relation.This result sheds additional light on the effectiveness of regularity / irregularity analysis tools based on the Myhill-Neroud theorem. In addition, the proved theorem and analysis of some examples of strongly separable relations allows us to establish non-trivial connections between the theory of formal languages and the theory of linear spaces, which, as analysis of sources shows, is relevant.In terms of development of the obtained results, the problem of the general characteristic of strongly separable relations is of interest, as well as the analysis of other properties of numerical sets that are important from the point of view of regularity / irregularity analysis of languages.

Proposals Regarding Work Strategies in Plastic Visual Activities III. Developing The Creative Behavior
Authors: Aprotosoaie-Iftimi Ana-Maria 
Published: April 2019

Abstract
Contemporary psychologist Didier Anzieu249 speaks of five phases of the process of creation: creative emotion, gaining consciousness, transposition, elaboration, and exposure. Each of the five phases has a correspondent in the stages of development of visual-plastic educational activities, and the role of the teacher is essential in each of them. Starting from the five phases, we propose an approach pattern to the creative process, adapted and developed during the years of experience in pre-university educational environment, and refined throughout the research activity carried out in the university environment.
Aggressive displacement of <i>Xylocopa nigrita</i> carpenter bees from flowers of <i>Lagenaria sphaerica</i> (Cucurbitaceae) by territorial male Eastern Olive Sunbirds (<i>Cyanomitra olivacea</i>) in Tanzania
Authors: Ollerton Jeff , Nuttman Clive 
Published: April 2019

Male Eastern Olive Sunbirds (Cyanomitra olivacea) and Xylocopa nigrita carpenter bees in Tanzania both utilise the flowers of male plants of Lagenaria sphaerica (Cucurbitaceae) as a source of nectar. The sunbirds set up territories defending this nectar resource. Observations of interactions between the sunbirds and the carpenter bees show that the bees are aggressively displaced from flowers when spotted by the birds. Only the bees can be considered as legitimate pollinators as the birds do not contact the anthers of the male flowers and were never seen visiting nectarless female flowers of Lagenaria sphaerica. Such territory defence may have implications for the frequency of movement and composition of pollen being transferred from male to female flowers which warrants further research.
Flobots: Robotic flowers for bee behaviour experiments

Published: April 2019

Studies of pollinator foraging behaviour often require artificial flowers that can refill themselves, allowing pollinators to forage for long periods of time under experimental conditions. Here I describe a design for inexpensive flowers that can refill themselves upon demand and that are easy enough to set up and clean that they can be used in arrays of 30 or more flowers. I also summarize of a variety of artificial flower designs developed by other researchers.

Published: April 2019

Children treated in hospitals have problems stressing the impact of hospital care, especially invasive actions. The efforts of pain management have been carried out mostly is the management of physical pain and the results of the research obtained are not fully optimal. Psychological children also need to be prepared besides physical management. Anxiety, fear and not understanding the procedure will contribute to the perception of pain. The purpose of this study was to identify stress levels in children who were infared after bibliotherapy. The research method chooses descriptive research with 15 quota sampling techniques. The data analysis used is descriptive analytic. Phase 1 of the Basic Scientific Research (PDK) research by performing psychological pain management using bibliotherapy, the storytelling method was obtained after bibliotherapy with a description of patients in the hospital as much as 2x a day and 50% of respondents experienced mild stress. This is because the bibliotherapy process with stories of children being treated in hospitals is able to make a picture of the situation that can be understood in preparing mentally for infasive actions.

Promoting Health from Outside the State: La Comunidad, Migrants, and Hometown Associations
Authors: Munoz Jose , Collazo Jose 
Published: April 2019

Migrants and organizational collectives, such as hometown associations (HTAs), have sent remittances to their countries of origin in an attempt to alleviate unmet health care needs. Additionally, migrants will use collective funds to rehabilitating roads; improving sewage systems and water quality; constructing recreational facilities; and refurbishing community buildings. All of these projects contribute to public health. The question explored in this paper is how remittances from abroad potentially contributes to the health of hometown communities. This focus on health and related issues allows for exploring HTA cross-border work as particularly informative in understanding state/society relations. In effect, we bring light to how a migrant transnational social movement can attempt to address health needs in its hometown. The Comparative Immigrant Organization Project (CIOP) is used to answer this question. For this paper, the level of analysis for the CIOP is organizational.
