CHEMICAL RECYCLING OF POLYMERS
Excessive growth in recent years on the market of plastics materials
has increased the amount of wastes. Therefore, there were made a lot of
researches on plastics materials in order to establish an economically viable
method of recycling, with low environmental impact. A method that meets these
conditions and witch does not require any washing and separation of polymers
and/or waste materials based on these polymers, is the chemical recycling by
“pyrolysis”. By pyrolysis process, wastes are converted into liquid fractions
close to commercial fuels, in certain reaction conditions. The results obtained
are influenced by the temperature and catalysts that were used. The paper is a
review of literature data related to chemical recycling of polymers.

A rehabilitation an intervention on a load-bearing structure, which
stops the deterioration of the historic load-bearing structures, maintaining their
present state: the geometrical-mechanical concept, the historic materials and
the traditional construction technologies (usually the interventions on a historic
load-bearing structure also entail consolidation works, not only the maintaining
of the present state, thus the term the conservation of a historic load-bearing
structure is rarely used). The conservation of the historic load-bearing
structures is related to: all those interventions which the present technical state

ELECTRIFICATION STUDY
The Engineer Dorin Pavel, „the father” of the Romanian hydroenergetic,
has published in 1925, as Assistant Professor at Zürich Technical
University, an „Electrification Study”. The study was related to the Romanian
Railways and it was printed in the General Romanian Engineering Association
(AGIR) magazine. After analyzing different electrification systems in Europe
and not only, he concluded: „I’m not an enthusiastic of the single-phase Swiss
system, but I think that the most efficient way would be to transform the 50
cycles three-phase current into 50 cycles single-phase current”. What
clairvoyance! The Congress of Lille recommended only in 1955 to use 25 kV,
50 Hz in new railway electrification works. The study continues with a proposed
schedule to electrify the CFR network in three 8 years stages, with the first
section between Bucharest and Brasov. So it was, but 35 years later: the first
overhead pole was erected in Predeal station on December 27, 1960. The last
part of the study shows the necessary power supply, based mainly on the
Romanian hydro potential.

ESSAI SUR LUCIAN BLAGA
Lucien Blaga est revenu dans la conscience du public roumain et
notamment des écrivains après la parution, en 1962 de deux livres de poésies,
Poemele luminii et Mirabila sămânţă (il faut y souligner: éditions posthumes).
L’expressivité de son lyrisme, la sensibilité des images des rêveries cosmiques,
le paroxysme de ses états d’âme ont livré aux poètes des générations 60 et 70
les clefs d’un renouvellement esthétique nécessaire après la période
prolétcultiste. Certainement, au cours des apparitions des livres du poète de
Lancrăm, le public de culture, y compris les enseignants dans leur démarche à
la classe, ont compris l‘envergure d’une synthèse littéraire et philosophique
dans l’esprit de l’éthos roumain à l’époque d’entre les deux guerres.

NUCLEAR ENERGY – PROS AND AGAINST – Part I
In January 2011, in 29 countries worldwide are operating 442 nuclear
reactors for electricity generation and 65 new nuclear plants are under
construction. In 2009, nuclear power plants in operation, have secured 14% of
world electricity production. Mainly, 16 countries rely on nuclear energy to
provide at least a quarter of their total electricity needed. Because high power
nuclear plants, waste products and the risks of using a nuclear reactor to make
a choice controversial, states with different attitudes regarding nuclear energy.
In Romania’s geographical area is under construction or design more Russian
nuclear reactors in the foreground, is deploying offensive Russian nuclear
attack: 12 reactors per 1,000 km of borders of Romania. After the disaster in
Japan, the future of nuclear energy is a subject of contention in many states,
and existing plants are subject to new safety testing in case of natural disaster.
The paper analyzes the situation of nuclear power in the world, noting
the advantages and disadvantages.

NUCLEAR ENERGY – PROS AND AGAINST – Part II
Undoubtedly, nuclear power will make a substantial contribution to
achieving sustainable electricity total. Many voices say nuclear energy: has fewer
emissions of pollutants, is effective, safe and soon it will reach the bottom of the
bag on oil, coal and gas. But nuclear plants do not operate simply clean. The
risks of nuclear power include: the risk of major accidents (like Chernobyl or the
Fukushima Daiichi), leakage of radioactive substances that can damage both the
environment and human health in the area, disposal of radioactive waste
resulting from the operation, the proliferation of nuclear weapons (in reactors use
natural uranium as fuel, as is the Cernavoda, it can produce plutonium used in
nuclear weapons, as happened in India in 1974 and later) etc.

CULTURAL CHARACTERISTICS AND ORGANIZATION
ACTIVITIES
The term „culture” represents a system of values, ethical norms,
thinking and acting models that are thought and accepted by a collectivity and
determine the given social group to act distinctly from other social groups.
The issue of organization culture is very often discussed in relation to
innovation. The common conception is that an entrepreneurship culture has a
strong effect on innovation. Conceptual arguments for the association between
cultural characteristics and entrepreneurship have existed for decades but only
in the last years has this relationship been more studied. Entrepreneurial
activities are considered an important source of technological innovation and
economic growth. Therefore, understanding the influence of national culture on
entrepreneurship is of considerable theoretical and practical value.
Culture and communication are inseparable. The way we
communicate, what we believe, what we say, the language choices we use,
and the nonverbal signals we employ are all a function of the culture we
acquire.

HEALTHY WORKPLACES – MAINTENANCE ACTIVITY
IN OCUPATIONAL HEALTH AND SAFE CONDITIONS
In practice, maintenance activities are part of the daily tasks of most
workers. Inadequate maintenance work, or not taken in time, can cause
irreparable damage to the equipment, but also very serious occupational
healthy problems. Maintenance workers are exposed to many and varied
hazards in the workplace. For this reason, maintenance work must be based on
risk assessment. A series of European directives aimed at determining the
general framework of minimum requirements for the safety of workers. Thus,
the employer must ensure the safety and health of workers in all aspects of
employment. From a financial standpoint, an inadequate management of
maintenance activities is extremely costly, and may involve loss of income.

Open conflict is opposition, the struggle between individuals or social
groups with divergent or incompatible destructive effects on social interaction.
This is a significant part of our life which, as mentioned numerous specialists in
human resources, there is inevitably, therefore it is difficult to imagine an
individual or organization that has not ever been involved in some type of
conflict. A minor conflict with opportunities for effective and immediate solution,
but which are delayed or misapplied degenerates, in most cases, in a major
conflict, its resolution approach involving additional expense of other
perspectives and resources. Conflict management includes a category of
preventive strategies and resolution, the competitive environment organization,
