    The economic crisis creates a series of consequences such as loss of jobs, reducing wages, insecurity of the population, reducing standard of living, material hardships, low self-confidence and hope for the better, illnesses, altered human relationships, social protests, ever greater scale strikes, in other words, deterioration of the economic environment. This paper aims to identify possible solutions to improve the effects of the crisis on the quality of life, based on figures from surveys conducted by research firms and the possible correlations to be made between these dates, without attempting to consider that these solutions are unique or the best. The main indicators considered for identifying the negative aspects of the crisis among the population are: the evolution of unemployment, changes in gross domestic product or wage developments in the economy and the share of expenditure linked to the basic needs out of the income earned. Regarding the possible solutions to reduce the population crisis, they are closely related to the credit and monetary policy, and also to the budgetary policy. Under the impact of the economic crisis, the business environment in Romania has suffered. Sub impactul crizei economice, mediul de afaceri din Romania a avut de suferit. Since most investments in 2008 were of foreign origin, the fact that this crisis has affected Romania as well did not surprise anyone. Nowadays Romania's business climate is characterized by lack of direct foreign investments and self funding sources whereas the population declares itself in a large proportion -more than 50% - to be affected by the crisis (1). Effects of the crisis can also be observed in the evolution of consumers' behavior who fearing layoffs and declining revenue, not only turned to buying the same products or to purchase cheaper products, but also to reducing the amount of the purchased products. The quality of social life is essential and strongly related to stimulating economic activity. Satisfaction felt by the consumer will determine the level of consumption and will influence and ultimately decide the supply level. An adequate economic policy in Romania to restore the balance between supply and demand in the market may induce a state of economic recovery. This should be the objective of anti-crisis policies.crisis, quality of life, unemployment rate, gross domestic product, wages rate, social conditions of life, economic environment

    D. virgifera virgifera is classified as a quarantine pest in Germany, therefore the trials, presented in this paper, were performed in the western part of Romania, where the pest is well established since more than ten years. The field tests were carried out in close collaboration with Banat’s University of Agricultural Sciences and Veterinary Medicine, Timişoara.On sites highly infested by D. virgifera virgifera, 1 m² plots in four replications per variable were planted with maize for the chemical treatments and alternative crops (cereals and weeds). Gauze covered hatch cages were used for weekly counts of the emerged adult Diabrotica during the hatch period from mid of June to mid of August.It could be asserted that matured cereals are no host-plants for the western corn rootworm. In four years of trials not even one adult beetle hatched in the related cages.Setaria viridis and Digitaria sanguinalis reduced the number of hatched imagines significantly, nevertheless some individuals survived. Therefore an effective herbicide management against grass weeds in maize is recommended to limit the chance of survival of the pest.Clothianidin and Tefluthrin are effective against D. virgifera virgifera. 20% to 100% efficiency was assessed in the trials, strongly depending on precipitation and soil moisture in time of application. The insecticides decreased the maize root injury caused by larvae of the western corn rootworm significantly.Keywords: Insecticides, crop rotation, host-plants, hatch cagesZum Einfluss verschiedener Wirtspflanzen und Insektizid Behandlungen auf die Populationsentwicklung des Westlichen Maiswurzelbohrers Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae)ZusammenfassungDa der Westliche Maiswurzelbohrer in Deutschland noch als Quarantäneschädling eingestuft wird, wurden die Untersuchungen in Westrumänien durchgeführt, wo der Schädling bereits seit mehr als 10 Jahren etabliert ist. In Zusammenarbeit mit Banat’s University of Agricultural Sciences and Veterinary Medicine, Timisoara, erfolgte die Anlage und Auswertung der Feldversuche.Auf Versuchsflächen mit hohem Diabrotica Besatz wurden 1 m² große Parzellen (in vierfacher Wiederholung) mit Mais, für die Durchführung der Insektizidanwendungen, sowie mit alternativen Kulturen (Getreide und Ungräser) bestellt. Schlupfkäfige, die über die Parzellen gestellt wurden, dienten der wöchentlichen Zählung der aus dem Boden schlüpfenden Käfer während der Schlupfperiode, von Mitte Juni bis Mitte August.Es konnte festgestellt werden, dass die weit entwickelten Getreidearten keine Wirtpflanze für den Westlichen Maiswurzelbohrer darstellten. In den vierjährigen Versuchen konnte kein Käfer in den entsprechenden Käfigen gefunden werden.Setaria viridis and Digitaria sanguinalis reduzierten die Anzahl der gefangenen adulten D. virgifera virgifera signifikant, einige Exemplare überlebten jedoch auch. Eine wirksame Ungras Bekämpfung im Mais und den nachfolgenden Kulturen wird deshalb empfohlen um die Überlebensmöglichkeiten für D. virgifera virgifera zu begrenzen.Clothianidin und Tefluthrin reduzierten die Anzahl der schlüpfenden Imagines. Wirkungsgrade von 20% bis 100% konnten ermittelt werden, weitgehend unabhängig von der Formulierung. Dabei war die Wirksamkeit der Insektizide sehr stark abhängig von der Bodenfeuchte bei und kurz nach der Anwendung. Die eingesetzten Präparate verminderten die Schäden an den Maiswurzeln signifikant.Stichwörter: Insektizide, Fruchtfolge, Wirtspflanzen, Schlupfkäfig

    The aim of this thesis is to present a solution for implementing the front end system of the Scintillator Pad Detector (SPD) of the calorimeter system of the LHCb experiment that will start in 2008 at the Large Hadron Collider (LHC) at CERN. The requirements of this specific system are discussed and an integrated solution is presented, both at system and circuit level. We also report some methodological achievements. In first place, a method to study the PSRR (and any transfer function) in fully differential circuits taking into account the effect of parameter mismatch is proposed. Concerning noise analysis, a method to study time variant circuits in the frequency domain is presented and justified. This would open the possibility to study the effect of 1/f noise in time variants circuits. In addition, it will be shown that the architecture developed for this system is a general solution for front ends in high luminosity experiments that must be operated with no dead time and must be robust against ballistic deficit

    In line with the development of science and technology today, especially in the field of electricity brought many changes in the use of electricity. Electricity is currently needed both industrial and non-industrial. Electricity needs are currently provided by PLN as the main power source. The flow of electricity from the electricity grid is not always continuous in its distribution, one day there must be a blackout that may be caused by interference with the transmission system or distribution system. To anticipate this outage, it is necessary to design an automatic control called an automatic transfer switch and to prepare a backup source, a 2000-watt power inverter. Automatic transfer switch is electrical equipment that functions as a controller of the process of switching the PLN electricity supply to the inverter power supply or vice versa automatically. In the operation of this automatic transfer switch can be operated manually and automatically. Where is in automatic mode, if there is a power outage on PLN this tool is useful for turning on and connecting the power inverter to the load automatically. When PLN revives, this tool will transfer the power source to the load from the power inverter to the PLN electricity. At this time technological advances are developing very rapidly, technology is an inspiration so that life in the world becomes lighter, easier and practical
