Why Networking matters?
Romulus OPRICA
Bulletin of the Transilvania University of Bra?ov. Series VII : Social Sciences and Law , 2012,
Abstract: The business bureaucracy, in general, makes the majority of the managers (both top and middle management) neglect a key matter of success (both personal and businesslike): networking. The present paper wishes to raise a series of questions regarding Herminia Ibarra’s theory referring to the networking styles of managers on the basis of her own research on a series of managers included in the 100 top young managers” catalogue of Business Magazin.

Abstract: The wheat (Triticum aestivum), is one of the most important crops in the world and plays a special role human nutrition. Salt stress has became a severe global problem in the last decades and salinity is one of the most important abiotic factors limiting plant growth and yield, affecting morphological, anatomical, biochemical and physiological characteristics in plants. One of the biochemical parameters affected by salinity is protein synthesis. Therefore, the aim of this study is to investigate the NaCl treatment effect on protein content of three seedlings wheat cultivars (Faur, Iasi 2, Fundulea). The results evidenced that saline treatment determined modifications of soluble protein content at the early stages of seedling development depending on: the type of cultivar, the intensity of salt exposure (50mM, 100mM, 150mM and 200mM) and the age of seedling.

Abstract: Salinity is one of major environmental factors limiting agricultural production and has a considerable effect on world agriculture. Wheat is one of the main crops occupying a large area in the world. For these reasons, we studied the effect of the saline stress on the activity of some antioxidative enzymes at this graminaceous plant. As biological material, we used seeds of three wheat cultivars (Faur, Fundulea and Ia i 2) which were treated with different NaCl concentrations. Simultaneously, three controls not exposed at treatment were prepared. The dynamics of catalase and peroxidase activities was determined at 96h, 168h and 240h, namely in early stages of ontogeny. The results evidenced that the saline stress determined modifications of seedlings enzyme activities, at the three moments of analysis, depending on wheat variety and tested concentration of NaCl solutions.

Abstract: This paper presents the effect of microwaves on the catalase and peroxidase activity in rape germinating seeds. Two experimental lots were projected: one in which the non germinated seeds were exposed 1 hour, respectively, 5 hours, to microwave rays, and the second in which the germinated seeds (after 24 hours) were exposed to microwave action for the some interval. We used a microwave generator with a horn antenna, at the 10.75 GHz and a power density under 1 mWcm-1. For a period of 8 days, the dynamics of the catalase and peroxidase activity were analyzed at 2 days, 4 days, 6 days and 8 days. The results showed that the microwaves determined variations of catalase and peroxidase activities depending on the age of the plants, time of exposure to microwave action and state of seeds (germinated and non germinated) exposed to microwave.
Health Newscasts for Increasing Influenza Vaccination Coverage: An Inductive Reasoning Game Approach

PLOS ONE , 2011, DOI: 10.1371/journal.pone.0028300
Abstract: Both pandemic and seasonal influenza are receiving more attention from mass media than ever before. Topics such as epidemic severity and vaccination are changing the way in which we perceive the utility of disease prevention. Voluntary influenza vaccination has been recently modeled using inductive reasoning games. It has thus been found that severe epidemics may occur because individuals do not vaccinate and, instead, attempt to benefit from the immunity of their peers. Such epidemics could be prevented by voluntary vaccination if incentives were offered. However, a key assumption has been that individuals make vaccination decisions based on whether there was an epidemic each influenza season; no other epidemiological information is available to them. In this work, we relax this assumption and investigate the consequences of making more informed vaccination decisions while no incentives are offered. We obtain three major results. First, individuals will not cooperate enough to constantly prevent influenza epidemics through voluntary vaccination no matter how much they learned about influenza epidemiology. Second, broadcasting epidemiological information richer than whether an epidemic occurred may stabilize the vaccination coverage and suppress severe influenza epidemics. Third, the stable vaccination coverage follows the trend of the perceived benefit of vaccination. However, increasing the amount of epidemiological information released to the public may either increase or decrease the perceived benefit of vaccination. We discuss three scenarios where individuals know, in addition to whether there was an epidemic, (i) the incidence, (ii) the vaccination coverage and (iii) both the incidence and the vaccination coverage, every influenza season. We show that broadcasting both the incidence and the vaccination coverage could yield either better or worse vaccination coverage than broadcasting each piece of information on its own.
Search For New Physics at BABAR
Godang, Romulus
High Energy Physics - Phenomenology , 2013,
Abstract: Using a full BABAR data sample of 426 $fb^{-1}$, we present improved measurements of the ratio ${\cal{R}}(D^{(*)}) = {\cal{B}} (\bar{B} \to D^{(*)}\tau^{-}\bar{\nu}_{\tau})/$ ${\cal{B}} (\bar{B} \to D^{(*)}\ell_{\ell}^{-}\bar{\nu}_{\ell})$, where $\ell$ is either electron or muon. We measure ${\cal{R}}(D) = 0.440 \pm 0.058 \pm 0.042$ and ${\cal{R}}(D^*) = 0.332 \pm 0.024 \pm 0.018$. These ratios exceed the Standard Model predictions by $2.0\sigma$ and $2.7\sigma$, respectively. The results disagree with the Standard Model predictions at the level of $3.4\sigma$. The ratios are sensitive to new physics contributions in the form of a charged Higgs boson. However, the access cannot be explained by a charged Higgs boson in the type II two-Higgs-doublet model.
Charm Decays and Spectroscopy at BABAR
Godang, Romulus
High Energy Physics - Phenomenology , 2013,
Abstract: We present searches for rare charm decays of the form $X_c^+ \to h^{\pm} \ell^{\mp} \ell^{(')^+}$, where $X_c^+$ is a charm hadron either $D^+$, $D_s^+$, or $\Lambda_c^+$, and $\ell^{(')^{\pm}}$ is an electron or muon. These modes are based on 384 $fb^{-1}$ of $e^+ e^-$ annihilation data collected at the $\Upsilon(4S)$ resonance with the BABAR detector at the SLAC National Accelerator Laboratory. We also present the flavor-changing neutral-current decays $D^0 \to e^+e^-$, $D^0 \to \mu^+ \mu^-$, and $D^0 \to e^{\pm} \mu^{\mp}$ that corresponds to an integrated luminosity of 468 $fb^{-1}$ of data. The decay $D^0 \to e^+ \mu^-$ is further lepton-flavor violating, and thus occur only through very slow neutrino mixing. These decays constitute sensitive probes for possible new-physics contribution. We report new limits on the branching fractions of these decays.
Romanian Democracy, Theory and Method
Romulus Brancoveanu
Sfera Politicii , 2013,
Abstract: This is a comment on the type of democracy in Romania, as illiberal democracy. Given the Romanian democratization process, we can hope that, in the future, all populisms and politicization will cease, and a true liberal and constitutional democracy will be installed, which will not be a Romanian democracy” as Paul Wolfowitz suggested to be exported in Iraq. The question is whether it is good or not to export” such a political model. Romanian democracy” could be an exporting model only as an alternative to dictatorship and under the assumption that it will be adjusted in time, under the external pressure.

Abstract: L'exposition à la tempête de neige des routes dans les plaines de Buz u. Les plaines des Buz u represéntent unes des plus vulnérables zones au phénomène de la tempête de neige. Cette phénomèn produit le plus grand dommage en ce qui concerne la functionnement des routes, causant souvent leur bloc. Les plus vulnérables routes dans cette zone, en fonction de leur importance économique, sont les routes reliant les villes de Buz u, Ramnicu S rat et Pogoanele avec les résidences du comté voisin, et la route européen 85 avec la région du Moldavie. La carte de la vulnérabilité des routes dans les plaines de Buz u montre que les routes plus exposé sont E85 et DN 22 (entre Ramnicu S rat et Br ila).

Physics , 2011,
Abstract: We report on the study of the decay $B^+ \to D^0(\bar{D0}) K^+$ where $D^0$ and $\bar{D0}$ decaying to $K \pi \pi^0$, with the Atwood Dunietz and Soni (ADS) method. We measure the ratios Rads, $R^+$, $R^-$ since the processes $B^+ \to D^0 \bar{K^+}$ and $B^+ \to D^0 K^+$ are proportional to $V_{cb}$ and $V_{ub}$, respectively, are sensitive to $r_B$ and to the weak phase $\gamma$.
