COOPERATIVE MOVEMENTS SETTING EXAMPLE FOR CLASSIC TEAMWORKS OF COUNTRYSIDES IN TRANSYLVANIA
Cooperative movements assured economic welfare of villages, led them to the way of becoming real citizens in the first half of the XXth century. By that period we can say that for improving competitivity advancing coops, and their social role is necessary. In an active coop continuous modernization is needed. This is due to global challenges and multinational companies, and also smaller dominant ones. This is why Hangya cooperative organisations are to be remembered for being the first in the Carpatian basin from the late 19th century. Manufacturers can realize their interests by building their own organizations. This is the cooperation of separate farmers, today dealing with very complicated transnational organizations. Realizing these may be the way to improve livings in the countryside, especially in the agriculture. Joining the following forms of groups is a unique and necessary way to reach these. By this the conclusion is: there must be an integrated network system for production branches controlled by coops with cooperative tenets in Transylvania. For this historical examples of helping farmers remain separate, reach markets must be known and adopted into today’s circumstances.Cooperatives of Transylvania, Judiciary bases, Improving competitiveness, Integrated product channel, Security of income, Community/Rural/Urban Development, Industrial Organization,
Continuum EoS for QCD with Nf=2+1 flavors
We report on a continuum extrapolated result [arXiv:1309.5258] for the
equation of state (EoS) of QCD with dynamical quark flavors. In this
study, all systematics are controlled, quark masses are set to their physical
values, and the continuum limit is taken using at least three lattice spacings
corresponding to temporal extents up to . A Symanzik improved gauge and
stout-link improved staggered fermion action is used. Our results are available
online [ancillary file to arXiv:1309.5258].Comment: Conference proceedings, 7 pages, 4 figures. Talk presented at 31st

Static quark-antiquark pair free energy and screening masses: continuum results at the QCD physical point
We study the correlators of Polyakov loops, and the corresponding gauge
invariant free energy of a static quark-antiquark pair in 2+1 flavor QCD at
finite temperature. Our simulations were carried out on = 6, 8, 10, 12,
16 lattices using a Symanzik improved gauge action and a stout improved
staggered action with physical quark masses. The free energies calculated from
the Polyakov loop correlators are extrapolated to the continuum limit. For the
free energies we use a two step renormalization procedure that only uses data
at finite temperature. We also measure correlators with definite Euclidean time
reversal and charge conjugation symmetry to extract two different screening
masses, one in the magnetic, and one in the electric sector, to distinguish two
different correlation lengths in the full Polyakov loop correlator. This
conference contribution is based on the paper: JHEP 1504 (2015) 138Comment: 7 pages, 4 figures. Talk presented at the 33rd International

Guidebook How to develop a Sustainable Energy Action Plan (SEAP) in South Mediterranean Cities
This guidebook is adapted to the South Mediterranean context from the Joint Research Centre’s (JRC) guidebook "How to develop a Sustainable Energy Action Plan", developed in 2010 to support the implementation of the Covenant of Mayors (CoM) initiative in European cities. Through the CES-MED project, the European Union has opened the CoM initiative to local authorities of ten southern Mediterranean countries (Algeria, Egypt, Israel, Jordan, Lebanon, Libya, Morocco, Palestine, Syria and Tunisia).
The purpose of this guidebook is to make energy efficiency and climate change mitigation measures relevant, achievable and compelling to local authorities in the southern Mediterranean context. Ultimately, it aims to enhance the competitiveness of municipalities and ensure their economic development while reducing dependence on energy imports and fossil fuels through the implementation of energy efficiency, renewable energy and other well-planned climate change mitigation actions at the local level. The guidebook provides detailed, step-by-step guidance to local authorities in southern Mediterranean countries to develop an effective Sustainable Energy Action Plan (SEAP). The process has four phases: initiation, planning, implementation, and monitoring and reporting. The choice and sequence of actions can vary according to the policies and measures already in place. This flexibility allows local authorities to develop a SEAP coherent with and effective for their local circumstances and objectives.JRC.F.7-Renewables and Energy Efficienc
QCD transition temperature: full staggered result
We conclude our investigations on the QCD cross-over transition temperatures
with 2+1 staggered flavours and one-link stout improvement. We extend our
previous two studies [Phys. Lett. B643 (2006) 46, JHEP 0906:088 (2009)] by
choosing even finer lattices (N_t=16) and we work again with physical quark
masses. These new results [for details see JHEP 1009:073,2010] support our
earlier findings. We compare them with the published results of the hotQCD
collaboration. All these results are confronted with the predictions of the
Hadron Resonance Gas model and Chiral Perturbation Theory for temperatures
below the transition region. Our results can be reproduced by using the
physical spectrum. The findings of the hotQCD collaboration can be recovered
only by using a distorted spectrum. This analysis provides a simple explanation
for the observed discrepancy in the transition T between our and the hotQCD
collaborations.Comment: presented at the XXVIII. International Symposium on Lattice Field

(). For all our final results, the systematics are controlled, quark
masses are set to their physical values, and the continuum limit is taken using
at least three lattice spacings corresponding to temporal extents up to

Sustainable Energy Portfolios for Small Island States
The study presents a cost effective electricity generation portfolio for six island states for a 20-year period (2015-2035). The underlying concept investigates whether adding sizeable power capacities of renewable energy sources (RES) options could decrease the overall costs and contribute to a more sustainable, indigenous electricity generation at the same time. Often, island states rely on fossil fuels which apart from dependence on foreign resources also includes an additional, significant transport cost. This is an extra motive to study the extent in which island states represent primary locations for RES technologies. For the aims of the present study an optimization model has been developed and following numerous runs the obtained results show that installing PV and battery capacities can delay-reduce the huge investments in fossil options in early periods. Thus, investment on RES can have a positive, long-term effect on the overall energy mix. This prompt development can happen without adding new subsidies but there is a need to address the existing socio-economic barriers with intelligent design of financing and economic instruments and capacity building as discussed in the conclusions.JRC.F.7-Renewables and Energy Efficienc
A szteroidok elnevezése, felosztása és az emberi stresszfekélyek. Selye János 70 éve megjelent történelmi jelentőségű cikkei
Absztrakt
Selye János (Hans Selye) nevét főleg a biológiai stresszreakcióval kapcsolatban
ismerik világszerte, és még szakmai körökben is kevesen tudják, hogy Selye sok
más felfedezést is tett: Selyét a szteroidok a stresszreakció miatt
foglalkoztatták, hiszen tudta, hogy az adaptációs folyamatban a mellékvesekéreg
hormonjai kulcsszerepet játszanak. Selye állĂtotta fel körĂĽlbelĂĽl 70 Ă©ve a
szteroidok máig is ismert csoportosĂtását három tĂ©ny alapján: a) a csoportnevek
a szteroidokat termelő szervektől származnak (például a kortikoidok a
mellékvesekéreg ’cortex’-ből, a tesztoid/anabolikus szteroidok
a tesztiszből); b) logikus molekulaszerkezeti képleteken alapultak (például az
összes kortikoid 21 szénatomos pregnanszármazék); c) élettani hatásuk csoporton
belül azonos. Külön hangsúlyozzuk, hogy a glükokortikoid és mineralokortikoid
neveket is Selye vezette be a tudományos irodalomban, és ő fedezte fel ezek
gátló hatását a gyulladás kialakulására állatmodellekben, körülbelül 8–10 évvel
korábban, mint ezek klinikai alkalmazásáért egy gyakorló orvos megkapta a
Nobel-dĂjat. Selye másik nagy, mintegy 70 Ă©ves felfedezĂ©se az emberi
stresszfekélyek felismerése az akkor megjelenő klinikai esetek statisztikai
értékelése alapján, például a rakétatámadások után, egy-két nap alatt nagyon
megnőtt a fekélybetegek száma, és a londoni kórházakba perforált gyomor- vagy
nyombélfekély miatt felvett betegek száma megsokszorozódott a második
világháború alatt. Részben Selye-diákok és munkatársai kutatási eredményeiből
tudjuk, hogy a dopamin nyombĂ©lfekĂ©ly-kialakulás ellen vĂ©d, mĂg a TRH-nak Ă©s
endogĂ©n opioidoknak centrális gasztroprotektĂv hatása van. Tehát Selye János
sokkal többet tett az orvostudományért és gyakorlatért, mint „csak” a stressz
felfedezője. Orv. Hetil., 2015, 156(35), 1406–1414
