Pulmonary arterial hypertension (PAH) is a devastating, progressive disease with increasingly debilitating symptoms that leads to right heart failure and ultimately death if untreated.
We suggest that intrapulmonary delivery of autologous bone marrow derived mononuclear cells (BMMC-s) could be beneficial for patients with severe PAH.
We report on a patient with congenital heart disease (CHD) complicated with severe PAH, who received intrapulmonary autologous BMMC transplantation. For the examination of the results we used scintigraphy during the periods of 6, 14 and 27 months after cell transplantation and documented clinical and radiographical alleviation of PAH sypmtoms.
The obtained results suggest that intrapulmonary BMMC transplantation could serve as a new therapeutic option or supplemental therapy for deteriorating PAH, particularly in cases, when conventional therapeutic strategies have failed to provide the control of the disease.

Faced with various banking and financial crises, many works are wondering whether the money itself is the real problem or not! In 2009, a system of decentralized currency was born. This decentralized electronic money (which is known as Bitcoin), uses cryptography to perform these transactions. Free of state control (or central bank or financial authority), this new form of digital currency raises many questions. The purpose of this paper is to study the semiotics of Bitcoin, through the discussion of whether it really solves the crucial problem of trust model or not. And highlight the problems and difficulties raised by Bitcoin.
Our analysis shows that the Bitcoin digital currency based on the principle of peer-to- peer certainly highlights a number of significant advantages such as minimizing the maximum transaction costs and provides freedom of transactions without but it also eludes surveillance and that, beyond the resolution of the problem of trust model, this digital currency is not immune to a bubble, real issue of all banking and financial crises.

Journal of Scientific Research and Reports, Page 1710-1721
DOI: 10.9734/JSRR/2014/8981

Aims: Nowadays, teachers in Greece are facing rapidly changing working conditions with increased workload and working hours, severe pay cuts and high taxation. The purpose of the present work was to evaluate burnout and job satisfaction among Physical Education teachers in Primary Public schools in Greece.
Study Design: A survey of Physical Education teachers (n =132) received a questionnaire and responded to the survey (n =105, 79.5% response).
Place and Duration of Study: This work was carried out in the region of West Greece, in Primary Education Schools during the school year 2012-2013.
Methodology: A Pearson Correlation (results analysed with SPSS) was used to investigate possible correlations between the examined parameters.
Results: The results indicate that teachers exhibited moderate levels of job satisfaction (64.66 ±8.09), high levels of emotional exhaustion (26.14±9.37), low depersonalization (1.69±0.79) and personal accomplishment (38.61±5.36). Job satisfaction was inversely related with burnout (-0.433, P<0.05) but not related with demograppic parameters, such as age and gender. On the contrary, gender had a significant effect on the levels of emotional exhaustion (0.225, P=0.021) while family status had a significant effect on the personal accomplishment (0.272, P=0.004). Teachers were mostly satisfied with their working conditions, the work itself, their colleagues and mostly dissatisfied with working hours, salary issues and low prospects of professional development.
Conclusion: It is obvious that cut in salaries, decreased job security and deterioration of the working conditions had an impact on the previously established “heaven” of Public Servants in Greece. This information could be used by School Managers and the Greek Government for intiating correcting actions to reverse the trend exhibited in the present work.

Journal of Scientific Research and Reports, Page 1722-1737
DOI: 10.9734/JSRR/2014/10152

This project presents a new approach of a street lighting system that uses a photovoltaic produced energy controlled by a GSM (Global System for Mobile Communication). The case study was conducted in an open area of Al-Hesbah Street in Hebron. This system is based on installinga light fixtures supplied with 24V DC loaded by photovoltaic energy. Long life rechargeable batteries are used to provide energy back-up by means of photovoltaic panels. The GSM system provides a light control for turning the light on or off according to the environmental illumination level via computers. Laboratory tests have shown that this system can produce a massive amount of energy savings for the Palestinian community in Hebron; hence it is very promising and compromising solution.

Public expectations to move towards electric mobility are driven by various factors such as climate policy, high oil prices, and pollutants due to internal combustion engines. On the other hand, there is extensive public concern about the possible adverse health effects of electromagnetic fields (EMF) generated by electric vehicles. As electrical power and power electronics systems become more prevalent in transportation, the need for examining biological relevance of such systems becomes ever more important. In particular, it is necessary to pay special attention to magnetic fields (MF), because biological studies suggest that magnetic rather than electric component could be biologically effective. In this paper we present a review of observed EMF on electric vehicles (EV) and possible biological effects together with our research on measurements and analysis of magnetic fields encountered onboard public DC- and AC-powered vehicles. Maximum automotive magnetic field magnitudes varied from a few μT to 120 μT. For members of the general public, this range of exposures in personal scale electric transportation systems is comparable in magnitude to exposures from other commonly encountered sources. However, electric vehicles exposures are totally different from common power line exposures; they are characterized by the complex frequency content and specific waveforms. The obtained measurement information allowed characterization of specific magnetic field features that could be biologically plausible: wide frequency range, intermittency, interaction with DC-field and other aspects. We consider these specific features of transport EMF in regard to their biological relevance. The careful mapping of magnetic fields inside the vehicle at different operating conditions derived to the recognition of the main sources of magnetic fields. This information could be important both for possible mitigation and for electromagnetic compatibility issues.

The analysis of proximate, mineral, fatty acids and anti-nutritional composition of Bunaea alcinoe were carried out. Results showed that Bunaea alcinoe had moisture 5.03±0.12, crude protein 44.23±0.62, crude lipids 10.85±0.65, crude fibre 11.80±0.27, carbohydrate 22.16±1.09 g100g-1 and energy value of 1530.08±0.06 kJ/100 g. This insect contained reasonable amounts of sodium, potassium, calcium, phosphorus, magnesium, zinc and manganese. Anti-nutritional analysis revealed the presence of oxalate (15.47±1.88), phytate (18.21±2.14) and cyanide (1.68±0.20)mg/100g; which were within the permissible limits. The insect larvae could therefore serve as an additional promising sources of protein and mineral contents for Human and animal feeds formulations.

Journal of Scientific Research and Reports, Page 1815-1827
DOI: 10.9734/JSRR/2014/10790

A generalized two-component Camassa-Holm equation is introduced as a model for shallow water waves moving over a linear shear flow. Bifurcations of traveling wave solutions are studied. Phase portraits of the traveling wave system are given. By using the method of planar dynamical systems, the existence of solitary wave solutions, smooth and non-smooth periodic traveling wave solutions is presented in different parametric conditions. Numerical simulations are made to agree the theoretical analysis. It shows that the existence of singular straight lines for the generalized two-component Camassa-Holm equation is the original cause of the non-smooth solutions. The existence of uncountably infinitely many breaking traveling wave solutions are given.
