Implementation of MPPT for PV Isolated System by P&O, I_C and PSO Methods based on Arduino Technology
Authors: Gouda Eid A. , Kotb Mohamed Fawzi , Elalfy Dina A. 
Published: November 2019

Maximum power point tracking (MPPT) algorithms are very important for the PV systems because they attract the points of maximum power at any conditions of the varying temperature and irradiation and subsequently decrease the PV array cost. This paper presents an improved MPPT technique for the PV system using particle swarm optimization (PSO) algorithm comparing with the conventional MPPT methods using perturb and observe (P&O) and incremental conductance (I_C). MATLAB simulations are carried out under the same irradiation and temperature and a variation in the load and comparing the performance of the three methods. In Protues 8.3 professional software, a design of the proposed model using Arduino UNO of the three algorithms is achieved. One of the important contributions of this paper is the proposed experimental work which is carried out by the combination of Arduino UNO which is coded by C language and coupled with MATLAB results which obtained by the simulation for the used different optimization methods in this paper. At the end of this paper, there is a comparison in tabular form between the presented 3 optimization methods with their experimental results. It is found that the results obtained by using PSO are more acceptable.
The main advantages of the PSO are as follows: - it reduces the oscillations at the steady state (to approximately zero) once the MPP is located, and its algorithm is very fast comparing to the other two methods.

Published: November 2019

Clozapine (CLO) is an effective atypical antipsychotic to control the symptoms of psychosis and schizophrenia. Clozapine has low solubility and high permeability, so it is classified as a class II in the biopharmaceutical classification system. The aim of this study was to improve the solubility and dissolution rate of clozapine by clozapine-isonicotinamide (CLO-INA) co-crystal formation. CLO-INA co-crystal was prepared by solvent-drop grinding (SDG) method using water as a solvent. Characterization of SDG result was conducted by powder X-ray diffraction (PXRD) and Fourier transform infrared (FTIR). Solubility test was performed in water at room temperature. The dissolution test was performed in 900 mL of pH 6.8 phosphate buffer solution, 50 rotation per minute of paddle rotation, and at 37±0.5 °C. The PXRD pattern of SDG result of CLO-INA has many different peaks from its parent components, and this may indicate the co-crystal formation. The solubility of the co-crystal clozapine was fifteen folds higher than pure clozapine. The dissolution rate of CLO-INA co-crystal increased in the first 10 minutes compared to pure clozapine. Percentage of clozapine dissolved after 10 minutes from CLO-INA co-crystal and pure CLO were 10.2 and 2.4%, respectively. CLO and INA can form co-crystal by SDG method that can improve the solubility and dissolution rate of clozapine.Keywords: Clozapine, Isonicotinamide, Co-crystal, Solubility, Dissolution
Integration of Relational and Graph Databases Functionally
Authors: Pokorný Jaroslav 
Published: November 2019

Abstract
In today’s multi-model database world there is an effort to integrate databases expressed in different data models. The aim of the article is to show possibilities of integration of relational and graph databases with the help of a functional data model and its formal language – a typed lambda calculus. We suppose the existence of a data schema both for the relational and graph database. In this approach, relations are considered as characteristic functions and property graphs as sets of single-valued and multivalued functions. Then it is possible to express a query over such integrated heterogeneous database by one query expression expressed in a version of the typed lambda calculus. A more user-friendly version of such language could serve as a powerful query tool in practice. We discuss also queries sent to the integrated system and translated into queries in SQL and Cypher - the graph query language for Neo4j.

Abstract
We lost a man - a person always rational, always free and gifted with the soul. We lost a man mainly in the space of language. Instead of a human is “individual” - a measure. This process has already accelerated in the second half of the 19th century. There is no human being anymore, there are individuals with a definable quality, and to segregate and destroy those who do not correspond to the desired image. Also in globally meant social aid. There is a need to go back to seeing the face of each human. Restore everyone.

Authors: Górska-Szymczak Joanna 
Published: November 2019

Abstract
The aim of this article is to analyze which issues, and why, influenced the systems of education at the turn of XX and XXI century to the extent that led to the need of resolving them at the level of international tribunals in Europe - the Court of Justice of the European Union (CJEU) and the European Court of Human Rights (ECtHR). Within the case law of the CJEU, the analysis was based on the cases concerning the right to education of migrant children and the right of the holder of a secondary education diploma awarded in a Member State to access the higher education institution in another Member State. As far as the case law of the ECtHR is concerned, the author considers the cases dealing with the issue of wearing headscarves and displaying crucifixes in educational institutions in the context of the freedom of religion, the case with a problem of an alternative for religious education in public school and the cases on the discrimination in education. The conclusion is that the systems of education are vulnerable to challenges faced by the entire society and reflect the changes undergoing within it.

Published: November 2019

Abstract

Introduction. Interdisciplinarity and interprofessional networking are important basis for a successful, recognizable and innovative research. Nursing research is at the intersection of health, biomedical and social sciences. Demographic trends in developed countries require integration of health and social services.

Aim. To examine the trend of interdisciplinary approach in terms of addressing social care in connection with nursing care and especially in the field of nursing care of the elderly, we analyzed scientific publications in this field over the period 1998-2018 in the PubMed database.

Discussion. The analysis showed that the number of scientific publications considering social care aspect is growing relatively faster in comparison to those addressing nursing care, especially when addressing elderly population. Development of study programmes should follow the needs of the society so that universities will educate professionals that will be able to tackle emerging problems and issues. Involvement of students in the research projects, dealing with relevant health and social care issues can significantly contribute to gaining required competences.

Conclusions. The obtained publication data are reflecting the current trends of integration of health and social care services in practice and research. Interdisciplinary study programmes as well as engagement of students into relevant research projects are important for the efficient and quality development of care services.

Authors: Kojicic Ksenija 
Published: November 2019

Abstract
The study was conducted at the Clinical Centre Kragujevac, during the period March-May 2016. The study population consisted of patients older than 65 that were treated at different departments of the Clinic for Internal Medicine. Data were collected from hospital medical records of patients and anonymous semi-structured questionnaires. STOPP (screening tool of older people's prescriptions)/ START (screening tool to alert to right treatment) criteria from 2014 were used to monitor the outcome of interest. Based on the outcome PIM (potentially inappropriate drugs)/PPO (potential prescribing omissions), respondents were divided into groups of cases - patients to whom at least one potentially inappropriate drug determined by STOPP criteria was prescribed and those with at least one potential prescribing omission determined by START criteria. Control groups were patients without these outcomes. Most commonly, PIM was detected in the treatment of cardiovascular system diseases (27.12%), followed by the use of drugs that predispose falls in elderly (20.34%). The most important risk factors for the occurrence of PIM were female gender (OR=3.27; 95% CI 1.01-10.64), polypharmacy (5-8 drugs used simultaneously) (OR=3.10; 95% CI 1.11-12.04) and with whom the patient lives (OR=11.26; 95% CI 1.46-86.68). The use of STOPP/START criteria is proved to be efficient in the detection of PIM/PPO at the secondary level of health care. Full attention should always be paid to patients who are at the highest risk for inappropriate drug prescription. Doctors should make their decisions conscientiously and in line with clinical evidence, not blindly believing the pharmaceutical representatives.
The Connection of Periodontal Disease and Diabetes Mellitus: The Role of Matrix Metalloproteinases and Oxidative Stress

Published: November 2019

Abstract
Diabetes mellitus, a chronic disease considered by the World Health Organization to be an epidemic, is now recognized as one of the factors behind the onset of periodontal disease. The connection between periodontal disease, which is an irreversible inflammatory disease of the supporting tissue of the teeth, and systemic diseases is reflected in the existence of common risk factors, subgingival dental biofilm, as a constant source of proinflamma-tory cytokines synthesized intensely in inflammatory periodontium. Diabetes mellitus leads to increased oxidative stress in periodontal tissues causing worsening of the disease and periodontopathy exacerbates deficiency of pancreatic β-cells. The most important role in primary inflammatory response in the pathogenesis of periodontopathy is played by neutrophils. Neutrophils cause periodontium destruction by the release of enzymes (matrix metalloproteinases), cytotoxic substances (free radicals, reactive oxygen and nitrogen species) and the expression of membrane receptors. Matrix metalloproteinases within the “protease network” are critical to many physiological and pathological processes, including immunity, inflammation, bone resorption and wound healing. Matrix metalloproteinases levels are elevated in patients with metabolic syndrome and diabetes mellitus, which may contribute to more frequent complications. In this paper, the review of available literature data shows the correlation between periodontal disease and diabetes mellitus, as well as the role of matrix metalloproteinases and oxidative stress in these. In this regard, determining the value of matrix metalloproteinases may be helpful in the diagnosis of periodontal disease complicated by diabetes mellitus. Also, the parameters of oxidative stress could help to clarify the mechanisms of pathogenesis and etiology of periodontal disease, or indicate the potential benefit of antioxidant supplementation in these individuals. As the role of matrix metalloproteinases has not been fully clarified in the pathogenesis of periodontopathy, additional studies will be needed to indicate their importance.

ÖzetSon
zamanlarda düşük enerjili ya da enerjisiz tatlandırıcılar enerji ve glisemik
etkilerden uzak oldukları gerekçesi ile şeker ikamesi olarak oldukça sık
kullanılmaktadırlar. Bu tatlandırıcı türlerinin saf olarak kullanılması dışında
günümüzde gıda ürünlerinin içerisinde sıkça bulunmaları tüketiciler tarafından
alımını oldukça artırabilmektedir. Tatlandırıcılar sağlık üzerine etkileri
açısından doğal ve yapay tatlandırıcılar olarak ikiye ayrılmaktadır. Deney
hayvanlarında yapılan çalışmalarda yapay tatlandırıcı tüketimi enerji dengesini
bozarak abdominal obezite, insülin direnci ve/veya bozulmuş glukoz toleransı
dahil olmak üzere birçok metabolik sendrom bileşeni ile ilişkilendirilmektedir.
Ayrıca karaciğer enzimleri ve oksidatif stres üzerine olumsuz etkisi olduğu da
bildirilmektedir. Ancak yapay tatlandırıcıların glukoz intoleransını artırdığı,
karaciğer enzimlerini ve oksidatif stres parametrelerini olumsuz etkilediğine
dair çalışmaların yanında anlamlı sonuç bulunamayan çalışmalarda mevcuttur. Bunun yanında doğal tatlandırıcıların insülin
duyarlılığını artırdığı, kan glukozu üzerinde yararlı etkilerinin olduğu,
karaciğer enzimleri ve oksidatif stres parametrelerini azaltıcı bir rol
oynadıkları belirli çalışmalarda bildirilmektedir. Fakat doğal
tatlandırıcıların bu parametreler üzerinde anlamlı etkisinin olmadığına dair
çalışmalarda mevcuttur. Bu nedenle bu derlemede doğal ve yapay tatlandırıcıların
glukoz intoleransı, karaciğer enzimleri ve oksidatif stres üzerine olan

Optimizing embryo stage and GA3 doses in Common mandarin x Carrizo citrange crosses on embryo rescue technique
Authors: KURT Senay , ÜLGER Salih 
Published: November 2019

Many difficulties are exist in citrus breeding
due to incompatibility, long juvenility, sterility and nucellar embryo. Zygotic
embryo in the seeds of polyembryonic citrus cultivar is degenerated by nucellar
embryos during embryo development. Accordingly, in vitro embryo culture is a
useful tool in citrus breeding, since it assures embryo germination and
development. In this study, Common mandarin x Carrizo
citrange were crossed in order to produce new rootstock genotypes.
Immature embryos were taken from fruit after 80, 100 and 120 pollination days
to determine the suitable embryo rescue stage. Then, the embryos were germinated in Murashige and
Tucker (MT) culture medium including 0, 0.5 and 1 mg l-1 GA3.
According to the results, high germination rates were materialized as 100% and
on 95% to taken embryos from 120 days after pollination (DAP) in supplemented
with 1 mg l-1 GA3 and 0.5 mg l-1 GA3
in MT culture medium respectively. The embryos
taken from 80 days after pollination did not germinate on MT medium without GA3
(control) and including with 0.5 mg l-1. Generally, the
existence of GA3 on medium increased the ratio of germination
compared to the control. The highest trifoliate ratio was determined as 33.33%
at the embryos taken from 100 and 120 days after pollination and medium
including 0.5 and 1 mg l-1 GA3 consecutively. The
results have revealed that the optimal time for embryo rescue at citrus is 120
DAP and including GA3 in the medium increased embryo germination.
