Fissidens Subgenus Aloma (Bryophyta) in Tropical Africa I. the Large-Celled Costate and Ecostate Species
Authors: Bruggeman-Nannenga Maria Alida 
Published: November 2017

Abstract
A revision of the large-celled costate and ecostate species of Fissidens subgenus Aloma Kindb. from tropical Africa is presented. Fissidens flaccidus var. mammillosus Brugg.-Nann. var. nov. is described and the Neotropical F. mollis Mitt. is reinstated. Most African specimens previously identified as F. enervis Sim are referred to Fissidens dealbatus Hook. f. & Wilson, a new indigene for Africa. Fissidens molliculus P. de la Varde, F. hedbergii P. de la Varde and F. hookerioides Bizot & Onr. in Bizot are subsumed under F. dealbatus. Fissidens enervis s.str. appeared to be a rare species. The distributions in O’Shea (2006) are revised, updated and, when necessary, amended. Fissidens flaccidus Mitt. is for the first time reported from South Africa and Guinea, F. zollingeri Mont. from Ghana, F. grandifolius Broth. & P. de la Varde from Cameroon and F. usambaricus Broth. from Malawi and Gabon. Pending further research, F. palmatus Hedw. is excluded from the African bryoflora. It is stressed that, since vegetative and perichaetial stems are different, perichaetial stems (and leaves of perichaetial stems) are to be compared with perichaetial stems (and leaves of perichaetial stems), whereas vegetative stems (and leaves of vegetative stems) should be compared with other vegetative stems (and leaves of vegetative stems).

Authors: Evsei Anca , Birceanu-Corobea Adelina , Melinte Violeta , Sarafoleanu Codrut 
Published: November 2017

Abstract

BACKGROUND. Primary sinonasal mucosal melanoma is a rare tumor with a poor survival rate. There is an inherent difficulty in diagnosing these lesions, especially because their complex anatomic locations and symptoms can be frequently confused with other benign or malignant processes. The purpose of our study was to report a difficult case and review the literature and recent research on therapeutic modalities.

MATERIAL AND METHODS. We herein report a 61-year-old female patient, with a history of right eye enucleation and prosthesis, who presented with obstruction of the left nostril, anterior and posterior mucopurulent rhinorrhea, anosmia, left facial numbness, left exophthalmia accompanied by ipsilateral epiphora and decreased visual acuity.

RESULTS. Clinical and imagistic testing revealed a large, grayish, fleshy tumor localized in the left maxillary sinus, with extension to the left orbit (producing osteolysis of the inferior and medial orbital walls), nasopharynx, ethmoidal cells and left frontal sinus. Pathological and immunohistochemical examination confirmed the diagnosis of mucosal melanoma. Other primary sites were excluded. The patient succumbed shortly after, following only palliative treatment.

CONCLUSION. Early diagnosis of primary sinonasal mucosal melanoma is essential but very difficult to detect. Any symptoms such as unilateral epistaxis or nasal obstruction in a patient over the age of 60 should be rendered suspicious. Pathological and immunohistochemical examination for diagnosis and prognostic factors are important. Although surgery is the first option for treatment, one must consider, according to tumor staging, radiotherapy and chemotherapy with immunotherapy as a viable course of treatment for advanced cases.
Signal void and pseudo-pneumatized sinus in fungal rhinosinusitis – Case report
Authors: Vuzitas Alexis , Petrica Marian , Manea Claudiu 
Published: November 2017

Abstract

BACKGROUND. Signal void, or the absence of signal on MRI sequences, in the sinonasal region may be encountered in fungal rhinosinusitis cases with the aspect of a pseudo-pneumatized sinus, leading to diagnostic errors.

CASE REPORT. We present the case of a 75-year-old woman referred to our clinic for complete and persistent right-sided nasal obstruction. The patient was evaluated using sinus CT and contrast-enhanced head MRI. Opacification of the right maxillary, ethmoid and frontal sinuses as well as of the right nasal fossa were seen on CT, with maxillary sinus expansion and osseous erosion. The MRI showed T2 signal void in the maxillary sinus with extension to the nasal fossa, creating the appearance of a pseudo-pneumatized sinus, and hyperintense signal in the ipsilateral anterior ethmoid and frontal sinuses. The patient underwent endoscopic sinus surgery. The dual imaging evaluation of the patient aided the preoperative differential diagnosis and choosing the surgical approach.
Investigation on the Relationship between Microstructure and Fracture Properties of Self-Compacting Concrete (SCC)

Published: November 2017

Abstract
Self-compacting concrete (SCC) is a high-performance concrete that is increasingly replacing conventional concrete because of its many advantages. SCC is prepared with chemical and mineral admixtures to achieve increased flowability. These admixtures modify the microstructural characteristics of SCC, which in turn affect the mechanical and fracture properties of concrete. In this study, an attempt has been made to establish the relationship between the microstructure and fracture properties of SCC mixes. The fracture properties are studied by using the RILEM work of fracture method, Bazant’s size effect, and the Wittman boundary effect models. Microstructural characterization has been carried out using X-ray diffraction, scanning electron microscopy (SEM), and microindentation techniques. It is revealed that the presence of mineral admixtures alter the microstructural skeleton of SCC, which in turn increase its brittleness. However, it is also found that the reason for brittleness is not because of cracking through aggregates as is reported in many literature regarding high-strength concrete; on the contrary, the cracks are passing through the interfacial transition zone or matrix in all SCC mixes, as is revealed by SEM images. Furthermore, it is found that the mechanical properties of the aggregate used have a significant influence on the fracture properties of the mixes.
Tele Alert System for Epileptic Seizure on a Study of EEG Signal Classification by GBE-NLSVM through ICA Preprocessed and AR Extracted Signal in a BCI System
Authors: Velumani R. , Vijayakumar M. , Ramasamy M. 
Published: November 2017

Abstract
Brain computer interface is an action of translating the brain signal into a command for activating artificial object such as limb. BCI is the collaboration of biomedical, electrical, computer, and mechanical engineering. An action potential is created in the form of electrical signal in the brain for every action of a human being, either physical or mental. The patient himself suffering from epileptic seizure poses danger severely during the absence of continuous monitoring. Taking care of epileptic patients from remote locations has become essential since the patient loses his whole control during epileptic seizure. This paper presented an epileptic tele alert system (ETAS) for a patient being monitored from out of the hospital premises. The brain signals tapped using a noninvasive electro encephalographic (EEG) electrode was given to independent component analysis (ICA) to preprocess the tapped signal. The auto regressive method (AR) was employed to extract the feature from training the brain signal for the normal and abnormal condition of the patient. The support vector machine technique named Gaussian basis function non-linear support vector machine (GBF-NLSVM) was used to classify the signal that is a vulnerable point in the cause of the epileptic seizure with respect to brain action potential for various statuses of activities. The frequency beyond the beta level was identified and the signal was transformed as a command for activating handheld devices using microcontroller via global system for mobile communication (GSM). The MATLAB, Simulink software having built in functions for studying the brain signal was used to analyze the brain signal. The proposed model discussed the signal tapping, feature extraction, classification, and activation of mobile phone using microcontroller. The proposed system incorporating ICA, AR, and GBF- NLSVM was compared with other techniques for identifying epileptic seizure and ensured that the system provided about 97 % of accuracy over the other standalone technique.

Abstract
The inhibiting effect of three synthesized corrosion inhibitors that are based on Schiff base and named N-(3-(butylidene amino) propyl)-N,N-dimethyl decan-1-ammonium bromide, N-(3-(butylidene amino) propyl)-N,N-dimethyl dodecan-1-ammomium bromide, and N-(3-(butylidene amino) propyl)-N,N-dimethyl hexadecan-1-ammonium on the corrosion rate of mild steel in 1.0 M hydrochloric acid was monitored through gravimetric and electrochemical techniques at 25°C. The temperature effect ranging from 25°C to 70°C on the corrosion rate has been studied and used for predicting the adsorption isotherm and thermodynamic parameters. The propensity of the synthesized compounds to adsorb on the steel surface were found to obey Villamil adsorption isotherm. The inhibition efficiency was increased concurrently with a plethora of inhibitor concentration and a rise of the solution temperature. Polarization curves prove that the tested compounds act as mixed-type inhibitors. Double-layer capacitances of inhibitors decrease when compared to the blank solution.

Summary
Herein, we present a 14-year-old patient with short stature (134 cm) referred from Paediatrics to our department for complementary evaluation since growth hormone (GH) treatment failed to show any improvement. He was born premature and small for gestational age. Genital examination classified the patient as Tanner I–II with small penis and testicular size for his age. Biochemical analyses revealed normal GH levels with low serum insulin-like growth factor-1 (IGF-1). Molecular diagnosis confirmed several mutations in IGF1R and IGFALS, and so he was diagnosed with Laron Syndrome or GH insensibility and treated with IGF-1 substitutive therapy.

Learning points:

Evaluation of the GH/IGF-1 axis when short stature does not respond to conservative treatment must be included in the ordinary practice.

Laron Syndrome real incidence should be calculated once undiagnosed cases arise, as treatment, due to lack of market, is unaffordable.

Even when adulthood is reached, and no longitudinal growth can be achieved, still IGF-1 treatment in Laron Syndrome patients should be pursued as metabolic and protective derangements could arise.
Procesos de significación: una mirada pragmática a los mensajes publicitarios de compañías telefónicas en la web
Authors: López Lozano Juana Alejandra 
Published: November 2017

Tomando como horizonte teórico la pragmática y los datos obtenidos tras el seguimiento de mensajes publicitarios de cuatro empresas de telefonía celular en Colombia, este artículo reflexiona acerca de los procesos de significación de los mensajes publicitarios online, en términos de la redundancia de códigos y de los contextos de interpretación previstos en el mensaje. Este acercamiento preliminar mostró que la redundancia orienta los procesos de significación de los destinatarios del mensaje publicitario en dos sentidos: contribuye a preservar las intenciones comunicativas que han motivado la producción del mensaje y privilegia la construcción de contextos interpretativos que favorecen su significado.

Published: November 2017

Abstract
The national values from studentsâ€™ point of view are analysed in the article, aiming to answer the questions: which national values are the priority, what does it mean today to be a true representative of the nation, what factors influence studentsâ€™ expression of national values. Todayâ€™s young people are characterized by high flexibility, mobility, adaptability to changing living conditions, constantly changing rules and norms. Every day new technologies are invented, a variety of new information flows promoting more different ideas. Therefore, youthâ€™s understanding of things and their use, attitude toward traditional relationships in society, family change, national values are viewed differently. In the article it is discussed whether globalized trends influenced the value position of respondents, and based on authors of pedagogy the attempt is made to uncover why in such society it is important to preserve the fundamental national values. The answers to these questions are based on the studentsâ€™ of Lithuanian University of Educational Sciences survey carried out in 2016 and theoretical insights, which justify the importance of national values in modern society and their expression.

Impact of acid precipitation on historical monuments and statues
Authors: Gurgen Gurcan 
Published: November 2017

Abstract A host of deleterious factors can impact the aging and integrity of historical monuments and statues. These may include natural causes such as water, wind, and temperature variation as well as the even more detrimental human causes of industrial pollution, urban warming, and fossil fuel emissions from vehicles all of which contribute to the development of acid precipitation. In addition, where the use of fossil fuels is wide-spread the occurrence of acid precipitation tends to be more prevalent and as a result serious damage can occur to the natural environment. Acid precipitation causes irreparable damage to vegetation, wildlife, and fish populations in lakes, streams, and rivers. Also, damage caused by acid precipitation can be quite recognizable on historical monuments and statues constructed from carbonate-based stone. The stone derived from carbonate sources such as limestone, dolomite, and marble have been widely used for thousands of years in the construction of monuments and statues. Carbonate-based stone was often chosen because of its abundance, suitability for shaping, and robust quality. Many historic works of art which not only characterize a period of art but also create powerful images of the artist and artwork have survived for thousands of years. The emergence of acid precipitation though has caused irreparable damage and destruction to many of these irreplaceable works of art, monuments, and statues. In this study, the research focuses on better understanding of acid precipitation and its impact on items of cultural heritage such as historical monuments and statues. Sample cases were chosen to emphasize and evaluate deleterious impact which may have occurred to these items of cultural heritage. According to research evaluation results from this study the researcher has provided recommendations for resolving the impacts of acid precipitation on these historical monuments and statues.

Published: November 2017

Abstract

The pre-professional training of students in children’s art schoolsrequires the development of a new methodology and content basis. This article examines the notion of the pre-professional development of graphical skills as a fundamental element of artistic training that includes Four components (cognition, knowledge, practice and motivation) and it is performed step-by-step. The application of an integrative approach is viewed as an effective means of the pre-professional development of teenagers’ graphical skills. The study describes the principle of integration applied for the artistic acquisition of the world. This integration approach has formed the base for the author’s original course, “Computer and Graphical Art” which was implemented at the experimental stage of this study. The diagnostics of the pre-professional development of graphical skills among teenagers in the experimental group demonstrated the effectiveness of the integrative approach. The research methods included observations, a survey, test, and expert evaluation. The article discusses details of teenagers’ graphical skills development within the integrative approach and experimentally proves the effectiveness of author’s original academic program.

Producers of contemporary art: X, Y, Z generations
Authors: İsitman Odul 
Published: November 2017

AbstractAccording to generational theory, individuals who share an era’s conditions, social events, distresses, and similar faith and who have similar responsibilities tend to show similar behavioral patterns. The question that the present study initially addressed was "What is the correspondence of this theory’s premises in the field of art with particular focus on contemporary art?’’ As the literature search proceeded, questions such as the following increased: Can this theory’s premises be the source of criticisms made in today’s art?, Could it be that art, like society, is also planned (or manipulated)?. Thus, the scopes that remain unanswered widened and the literature search was futile. It was deemed necessary to first outline an introductory general framework of the topic addressed. Accordingly, based on today’s discourse, an attempt was made to understand the correspondence between generations and contemporary art. This research will serve as a base for future studies on this topic.

Published: November 2017

AbstractCurrently, the Internet has become a part of the everyday life of human beings. The way of communication between people has changed and social networks are dominating in the lives of everyone. One of the most used social networks is Facebook, but besides that it is used for communication and entertainment, Facebook can also be used for learning. Therefore, the main issue of this paper is the use of Facebook for educational approaches by students and teachers. Case studies are the challenges of integration of Facebook in High Education in the municipality of Kumanovo in the Republic of Macedonia in 2016. Special emphasis is devoted in usage of Facebook in schools as the main questions were whether students use Facebook to ask for help for assignments or any material, and do teachers use Facebook to post assignments and to communicate with students. To understand this, there are conducted two questionnaires, one to students and one to teachers and interviews with school principals, and finally responses of people who participated have been analysed. The result is that by joining Facebook in education, students are more motivated to learn, Facebook helps students to learn by sharing knowledge with each other and by using Facebook at school, teachers will find it easier to inform students.
