CPT Profiling and Laboratory Data Correlations for Deriving of Selected Geotechnical Parameter
Authors: Bulko Roman , Drusa Marián , Vlček Jozef , Mečár Martin 
Published: December 2015

Abstract
Currently, can be seen a new trend in engineering geological survey, where laboratory analysis are replaced by in situ testing methods, which are more efficient and cost effective, and time saving too. A regular engineering geological survey cannot be provided by simple core drillings, macroscopic description (sometimes very subjective), and then geotechnical parameters are established based on indicative standardized values or archive values from previous geotechnical standards. The engineering geological survey is trustworthy if is composed of laboratory and in-situ testing supplemented by indirect methods of testing, [1]. The prevalence of rotary core drilling for obtaining laboratory soil samples from various depths (every 1 to 3 m), cannot be a more enhanced as continues evaluation of strata and properties e.g. by CPT Piezocone (every 1 cm). Core drillings survey generally uses small amounts of soil samples, but this is resulting to a lower representation of the subsoil and underestimation of parameters. Higher amounts of soil samples make laboratory testing time-consuming and results from this testing can be influenced by the storage and processing of the soil samples. Preference for geotechnical surveys with in situ testing is therefore a more suitable option. In situ testing using static and dynamic penetration tests can be used as a supplement or as a replacement for the (traditional) methods of surveying.

Published: December 2015

Abstract
SOA is a popular paradigm for building distributed systems that has gained a great recognition over past years. There are two main approaches to implementing SOA: SOAP-based and RESTful Web services. In order to address problems of modeling and verification of Web services, several process calculi have been proposed for SOAP-based Web services but none for the RESTful Web services based systems. This article is a comparative survey on existing process calculi for SOA systems, also the existing attempts to formalize REST systems are discussed. The aim of the article is to see how process calculi for SOAP-based systems deal with different aspects of their modeling domain, and whether their approaches can be used to model RESTful and ROA systems. Finally, basing on the survey, requirements for a new process calculus specific for REST are defined.

Abstract

Acacia nilotica is a widely used plant in traditional medical practice in Northern Nigeria and many African countries. The aim of this study was to determine the toxicological effects of a single dose (acute) and of repeated doses (sub-acute) administration of aqueous extract of A. nilotica root in rodents, following our earlier study on antiplasmodial activity. In the acute toxicity test, three groups of Swiss albino mice were orally administered aqueous extract of A. nilotica (50, 300 and 2000 mg/kg body weight) and signs of toxicity were observed daily for 14 days. In the sub-acute toxicity study, four groups of 12 rats (6 male and 6 female) were used. Group 1 received 10 ml/kg b.w distilled water (control), while groups 2, 3 and 4 received 125, 250 and 500 mg/kg b.w of the extract, respectively, for 28 consecutive days by oral gavage. Signs of toxicity/mortality, food and water intake and body weight changes were observed. Biochemical parameters were analysed in both plasma and liver homogenate. In the acute and sub-acute toxicity studies, the extract did not cause mortality. A significant reduction in the activity of lactate dehydrogenase was observed at 250 and 500 mg/kg b.w, while alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase activities were significantly higher than control values at 500 mg/kg b.w. The aqueous extract of A. nilotica was found to be safe in single dose administration in mice but repeated administration of doses higher than 250 mg/kg b.w of the extract for 28 days in rats may cause hepatotoxicity.

Authors: Patnaik Rajashree , Padhy Rabindra N. 
Published: December 2015

Abstract
This work describes that cytotoxicity of lead chloride and lead acetate to in vitro cultured lymphocytes from human umbilical cord blood, using four monitoring methods namely, trypan blue staining, acridine orange/ethidium bromide staining, 3-[4,5-dimethylthiazol-2-yl] 2,5-diphenyl tetrazolium bromide (MTT) and neutral red uptake assays; lead genotoxicity to lymphocytes was monitored by comet assay. The MIC value in each method was invariably 300 mg/L for PbCl2. Lethal concentration25 (LC25) values were almost in an agreeable range: 691.83 to 831.76 mg/L; LC50 values in each method were almost in the range: 1174.9 to 1348.9 mg/L; LC100 values were in the range: 3000 to 3300 mg/L, for lead chloride. Similarly, The MIC value in each method were invariably 150 mg/L; LC25 values were almost in the range: 295.12 to 371.53 mg/L; LC50 values were in the range: 501.18 to 588.84 mg/L; LC100 value was 1500 mg/L in all assays, for lead acetate. The comet assay also indicated that the LC100 values were 3300 mg/L lead chloride and 1500 mg/L lead acetate. Thus, both cytotoxicity and genotoxicity were recorded at 3300 mg/L lead chloride and 1500 mg/L lead acetate with lymphocytes.

Authors: Valcheva-Kuzmanova Stefka , Georgieva Antoaneta B. , Belcheva Stiliana P. , Tashev Roman E. 
Published: December 2015

Summary
Ferulic acid (FA), called also hydroxycinnamic acid, is a polyphenol compound found in many foods such as coffee, apples, rice, oats and wheat. It acts as an antioxidant but its other activities in vivo have not been well studied as a whole. The aim of the present study was to investigate the effects of FA on exploratory behavior and locomotor activity in male Wistar rats. FA was administrated orally (20 mg/kg) to different groups of rats for 7, 14, 21 and 30 days. These groups were compared respectively with saline-treated controls. At the end of each experimental period, the changes in exploratory behavior and locomotor activity were recorded in an Opto Varimex apparatus (Columbus Instruments, USA). The number of horizontal and vertical movements recorded every minute for the first 5 min served as a measure of exploratory activity and habituation to the new environment. The total number of movements during the first 5 min and during the whole 10-min period of observation was used as a measure of locomotor activity. It was found that FA at all doses for all treatment periods did not significantly affect exploratory behavior and locomotor activity of rats, when compared with the saline-treated controls. At all testing periods, FA did not disturb habituation. As habituation is considered an elementary form of learning, the present study suggested that FA did not disturb the memory and learning processes in rats.

Summary
The aim of this study was to identify risk sexual behavior in students aged 12-18 in Veliko Turnovo region. A cross-sectional study was carried-out in 2014. Three hundred and ten students attending seven schools filled in a self-administered questionnaire. The questionnaire included 48 questions, sixteen of which collected information about sexual behaviour, regarding contraception, casual sex with different partners, sexually transmitted diseases (STD), hygiene after sex, etc. The data were processed with SPSS.v.19. Parametric and non-parametric statistical methods were applied. Over 50% of the students reported being sexually active, most of them since they turned 16. Almost half of the respondents had had casual sexual partners and 46 percent had had sex within a week after initiation of a new relationship. Less than one third of the students reported safe sex behaviour. Seven percent of the students had a history of STDs, and one in six did not practice proper hygiene after sex. Identification of all aspects of risk sexual behavior in students aged 12-18 provides an opportunity to study the problem systematically and comprehensively. Planning and implementation of effective health education programs in schools require the application of an integrated approach with the participation of students, teachers, parents, health professionals and policy makers.
The effect of seizures on functional status of people with spastic forms of cerebral palsy
Authors: Michalska Agata , Wendorff Janusz 
Published: December 2015

SummaryBackground.Cerebral palsy (CP) is the most common childhood motor impairment. Epilepsy affects approximately one third of patients with CP. It is characterized by earlier disclosure, it is more severe and shows greater resistance than that of the general epilepsy treatment, associated with necessity for polytherapy. Its presence can result in gradual loss of function, loss of posture in non-ambulant individuals with severe disabilities and cognitive impairment risk, behavioural disorders and reducing probability of walking.Aim.The aim of the study was to evaluate the functioning of people with CP with and without epilepsy.Material and Methods.The study included 210 patients with a diagnosis of CP, aged 0–18 years. The study was conducted among the patients using the physiotherapy services in centres in southern Poland. The study used the Paediatric Evaluation of Disability Inventory (PEDI) and the classification systems: GMFCS, MACS, and CFCS.Results.There were significant differences with regards to social functioning (53.7/67.4; W = 179, p = 0.006) and support in the social functioning (65.4/89.9; W = 185.5, p = 0.007) in patients with diplegia. However, mobility (19.55/29.00; W = 392, p = 0.018) and the social functioning (36.95/44.1; W = 418.5, p = 0.042) were lower in epileptic patients with tetraplegia. In patients with hemiplegia, there were no significant differences, although each domain with epilepsy subgroup had a lower rating than the subgroup without epilepsy.Conclusion.The presence of epilepsy is associated with lower levels of social function in patients with cerebral palsy; particularly, with regard to mobility and selfservice.Assessment of epilepsy impact on the level of social functioning of people with CP (diplegia, tetraplegia, hemi-plegia) is difficult because ambiguous relationship with mental retardation. The assessment should be undertaken separately for each group of spastic CP.
Diagnosis of epilepsy – consequences for work and professional activities
Authors: Knieß Tobias , Stefan Hermann , Brodisch Peter 
Published: December 2015

Summary
Introduction. The correct diagnosis of epileptic seizures and non-epileptic attacks has a decisive influence on treatment, counseling and duration of possible work limitations.
Diagnostic efforts should aim towards classifying the seizure as precisely as possible. For risk assessments, e.g. at the workplace, a close cooperation and networking of all professionals involved in the epilepsy treatment, care and consultation processes is required.
Aim. To present guidelines for assessment of occupational capacity of persons with epilepsy and to discuss their value in clinical practice.
Method and Material. The German employer’s liability insurance association has recently published the new revised BGI 585 Risk Assessment Guidelines (DGUV information 250-001) framework and assistance in epilepsy in view of protection against unfair dismissal. These guidelines provide information on safety and health in the workplace.
Throughout all the German federal states, 24 Network teams were established. During the period January 2010 and December 2013, 374 employees with epilepsy were consulted by an expert member of Network Epilepsy and Work (NEA) Team, of which 80 were prospectively included in a study and scientifically evaluated.
Guidelines and discussion. While conducting the risk assessment, a special medical fact check in accordance with the guidelines was used. In addition to medical aspects, the individual vocational and occupational situation was considered. Based on this assessment an individual recommendation was made relating to continuation of employment. The project NEA established regional teams of physicians, therapists, consultants from social services, employment offices and rehabilitation authorities across Germany in order to link by networks the complex medical and social aspects of reducing the risk of people with epilepsy losing their job.
Results. It was shown that support and consultation through the NEA team led to an endangered position of employment being maintained in 70% of cases.
Conclusion. In many cases, loss of employment can be prevented by consequent application of DGUV information 250-001 (recently revised from BGI 585) for risk assessment of epilepsy in employment, together with improved networking between medical professionals, occupational health professionals and social services.
The role of cannabinoids and endocannabinoid system in the treatment of epilepsy
Authors: Pędracka Monika , Gawłowicz Jacek 
Published: December 2015

Summary
Introduction. The treatment of epilepsy is still a major challenge. Despite the introduction of many new antiepileptic drugs, approximately 30% of patients still remain drug resistant. In the absence of a satisfactory therapy outcome, which is sometimes associated with numerous side effects, there is a need for new and effective drugs with low toxicity. Cannabinoids have been shown in preliminary animal model studies and in studies of patients with epilepsy to have antiepileptic activity.
Aim. The aim of this paper is to review current reports on the role of the endocannabinoid system and cannabinoids in the treatment of epilepsy.
Methods. Articles from PubMed and Scopus published up to 2015 concerning the role of cannabinoids and the endocannabinoid system in the treatment of epilepsy are reviewed.
Review and Discussion. Cannabis has been used for thousands of years in the treatment of various diseases. They contain cannabinoids, which act on the endocannabinoid system which regulates many biochemical and physiological processes. By affecting glutamate and gamma-aminobutyric acid (GABA) neurotransmission cannabinoids have the ability to affect seizure threshold. The best known cannabinoid is cannabidiol, which inhibits the occurrence of seizures without causing significant side effects in humans and animals. However, only a small number of double blind, randomized and placebo controlled studies have been published to date.
Conclusions. The role of cannabinoids in the treatment of epilepsy is not well defined because these substances have shown pro-convulsive actions in some animal studies and also there are not many randomized trials performed to date. The existing human data do not support the conclusion that cannabinoids are effective and safe in the treatment of epilepsy, but do encourage further studies on a larger group of patients.

Published: December 2015

AbstractEqual access has serious implications for the growing chasm in learning in remote areas and in economically disadvantaged communities. To help bridge the digital divide for children in remote areas, engaging communities to provide the needed resources in remote schools is essential. With an aim to promoting teachers’ adaptation of tablet reading and teaching among remote schools, a platform for sharing experiences and exchanging ideas among teachers was developed. College students also volunteered for follow-up mobile reading promotion in order to provide needed human resources for tablet reading integration among disadvantaged communities. Collaborative efforts by the university and teachers in remote schools provided a case for study. The main issues explored in this study were: (1) how teachers in remote areas adapted tablet reading in the classroom, and (2) what university students experienced from promoting tablet reading. This paper presents a qualitative analysis of integrating volunteer services and civic engagement in promoting tablet reading, and highlights the mutual benefits, challenges, and recommendations for future implementation. Various data resources were integrated into the inductive analysis, and different resources were used for triangulating the reported phenomena. The study concludes that the teachers obtained experience of tablet reading, and the college students experienced innovative volunteer-service opportunities. The collaboration among the society, the university, and learning sites were all essential for promoting tablet reading among children in remote areas.

Enhanced luminescence of rare-earth Tb (III) obtained by mixing of Gd (III) in a fumarate complex and intra-molecular energy transfer
Authors: Shah M.D. , Want B. 
Published: December 2015

AbstractTrivalent lanthanide ions display fascinating optical properties. Therefore, the rare-earth complexes of terbium fumarate heptahydrate and GdTb fumarate heptahydrate were grown by using a single gel diffusion technique. The crystals were characterized by different physicochemical techniques of characterization. UV-Vis and photoluminescence spectrophotometric experiments were carried out to study the optical properties of the grown crystals. Under various excitations (339 nm, 350 nm or 368 nm) the terbium fumarate complex emitted characteristic (4f-4f) green emission of Tb3+ (5D4-7FJ, J = 6, 5, 4 and 3, respectively). Luminescence spectra showed that Gd3+ ions in the mixed complex have not affected the luminescence emission peak positions, but remarkably increased the luminescent intensities of the terbium complex. The energy-transfer mechanism between the ligand and the central Tb3+ ions and from the Gd3+ to the Tb3+ was discussed.

Published: December 2015

AbstractThe paper presents an investigation on crystalline, elastic and electronic structure in addition to the thermodynamic properties for a CeRu4P12 filled skutterudite device by using the full-potential linear muffin-tin orbital (FP-LMTO) method within the generalized gradient approximations (GGA) in the frame of density functional theory (DFT). For this purpose, the structural properties, such as the equilibrium lattice parameter, bulk modulus and pressure derivatives of the bulk modulus, were computed. By using the total energy variation as a function of strain we have determined the independent elastic constants and their pressure dependence. Additionally, the effect of pressure P and temperature T on the lattice parameters, bulk modulus, thermal expansion coefficient, Debye temperature and the heat capacity for CeRu4P12 compound were investigated taking into consideration the quasi-harmonic Debye model.
Whose Cosmopolitanism Is It Anyway? Musings from the Global Academy
Authors: Horta Paulo Lemos , Roth Nadine 
Published: December 2015

AbstractNew York University Abu Dhabi was inaugurated in 2010 with the express aim of producing global citizens, adept at crossing ethnic, national, and religious borders and exemplifying a certain kind of cosmopolitan ethic. This mission was tightly bound with the brand of cosmopolitanism articulated by Anthony Appiah and reflected most clearly in a core curriculum that emphasized cross-cultural and global inquiry. The desire to escape national paradigms was equally apparent in the distinctive curriculum of the history program, which was organized according to ocean systems and global patterns of transnational connection. Studied within this historical context, cities offer particular cognitive gains for students and researchers. As nodes of both imperial power and cosmopolitan ideals, cities complicate simple narratives of cross-cultural empathy and translatability. Despite its global connections, the contemporary city is confronted in its materiality as a sequence of boundaries and barriers. Within NYUAD as an institution, however, resistance to the core curriculum has emerged from other disciplines. The desire of the natural and social sciences for a “global” that is “universal” fits uneasily with the dream of a cosmopolitanism that leads to self-reflexivity in regard to one’s own values. And students themselves wonder, who is the cosmopolitan here?
