This paper examines the dynamics of sector concentration in Romania starting from two basic questions: how concentrated the economic activities are and what factors determine the economic concentration. The lack of availability of concentration ratio series for Romanian economy has limited the research in this field. The paper reports the concentration ratios dynamics in Romania during the period 1996–2004, looking at the differences between industries and offers some possible explanations. We use the simple concentration ratio (CR) for the largest 5 and 20 companies to measure concentration in 25 industries according to the sales figure and the number of employees. Our study has been limited to the processing industry, because the mining industry continues to have a very high level of concentration, without any significant changes in the analysed period; commerce, services and constructions are sectors with low entrance barriers and a strong geographic concentration character, thus their analysis can become irrelevant for the national level. Based on the average values of the concentration coefficients that it was determined for the period 1996–2004 we proposed the map of Romanian industry concentration, as a graphical tool for a synthetic view of the general concentration level in a national economy. Santrauka Nagrinejama tam tikru Rumunijos pramones sektoriu koncentracijos dinamika, atsakant i du pagrindinius klausimus: kokia yra ekonominiu veiklu koncentracija ir kokie veiksniai lemia ju pasiskirstym. Taèiau del kai kuriu ekonominiu apribojimu tyrimo metu nebuvo galimybes ivertinti tam tikru aspektu, nuo kuriu ir buvo atsiribota. Straipsnyje pateikiamas pramones sektoriu koncentracijos santykis, apimantis 1996–2004 metu laikotarpi, buvo nustatyti pramones šaku skirtumai ir pateikti komentarai. Autoriai daugiau demesio skiria apdirbamajai pramonei, nes kasybos pramone ir toliau išlieka viena iš labiausiai koncentruotu veiklos rušiu, dideliu pokyèiu tuose pramones sektoriuose analizuojamu laikotarpiu nebuvo pastebeta. Prekybos, aptarnavimo ir paslaugu bei statybos sektoriai turi nedidelius ribojimus, ir geografine koncentracija yra gera, todel ju analize buvo nustatyta kaip nereikšminga. Gauti tyrimo rezultatai naudoti sudarant Rumunijos pramones koncentracijos žemelapi ir nustatant lyginamji svori bendroje nacionalineje ekonomikoje.

A multisubunit RNA polymerase enzyme is ultimately responsible for transcription initiation and elongation of RNA, but recognition of the proper start site by the enzyme is regulated by general, temporal and gene-specific trans-factors interacting at promoter and enhancer DNA sequences. To understand the molecular mechanisms which precisely regulate the transcription initiation event, it is crucial to elucidate the structure of the transcription factor/DNA complexes involved. Electron spectroscopic imaging (ESI) provides the opportunity to visualize individual DNA molecules. Enhancement of DNA contrast with ESI is accomplished by imaging with electrons that have interacted with inner shell electrons of phosphorus in the DNA backbone. Phosphorus detection at this intermediately high level of resolution (≈lnm) permits selective imaging of the DNA, to determine whether the protein factors compact, bend or wrap the DNA. Simultaneously, mass analysis and phosphorus content can be measured quantitatively, using adjacent DNA or tobacco mosaic virus (TMV) as mass and phosphorus standards. These two parameters provide stoichiometric information relating the ratios of protein:DNA content.

The forte of the Scanning transmission Electron Microscope (STEM) is high resolution imaging with high contrast on thin specimens, as demonstrated by visualization of single heavy atoms. of equal importance for biology is the efficient utilization of all available signals, permitting low dose imaging of unstained single molecules such as DNA.Our work at Brookhaven has concentrated on: 1) design and construction of instruments optimized for a narrow range of biological applications and 2) use of such instruments in a very active user/collaborator program. Therefore our program is highly interactive with a strong emphasis on producing results which are interpretable with a high level of confidence.The major challenge we face at the moment is specimen preparation. The resolution of the STEM is better than 2.5 A, but measurements of resolution vs. dose level off at a resolution of 20 A at a dose of 10 el/A2 on a well-behaved biological specimen such as TMV (tobacco mosaic virus). To track down this problem we are examining all aspects of specimen preparation: purification of biological material, deposition on the thin film substrate, washing, fast freezing and freeze drying. As we attempt to improve our equipment/technique, we use image analysis of TMV internal controls included in all STEM samples as a monitor sensitive enough to detect even a few percent improvement. For delicate specimens, carbon films can be very harsh-leading to disruption of the sample. Therefore we are developing conducting polymer films as alternative substrates, as described elsewhere in these Proceedings. For specimen preparation studies, we have identified (from our user/collaborator program ) a variety of “canary” specimens, each uniquely sensitive to one particular aspect of sample preparation, so we can attempt to separate the variables involved.

Purpose A questionnaire survey was conducted to collect information from clinical audiologists about rehabilitation options for adult patients who report significant auditory difficulties despite having normal or near-normal hearing sensitivity. This work aimed to provide more information about what audiologists are currently doing in the clinic to manage auditory difficulties in this patient population and their views on the efficacy of recommended rehabilitation methods. Method A questionnaire survey containing multiple-choice and open-ended questions was developed and disseminated online. Invitations to participate were delivered via e-mail listservs and through business cards provided at annual audiology conferences. All responses were anonymous at the time of data collection. Results Responses were collected from 209 participants. The majority of participants reported seeing at least one normal-hearing patient per month who reported significant communication difficulties. However, few respondents indicated that their location had specific protocols for the treatment of these patients. Counseling was reported as the most frequent rehabilitation method, but results revealed that audiologists across various work settings are also successfully starting to fit patients with mild-gain hearing aids. Responses indicated that patient compliance with computer-based auditory training methods was regarded as low, with patients generally preferring device-based rehabilitation options. Conclusions Results from this questionnaire survey strongly suggest that audiologists frequently see normal-hearing patients who report auditory difficulties, but that few clinicians are equipped with established protocols for diagnosis and management. While many feel that mild-gain hearing aids provide considerable benefit for these patients, very little research has been conducted to date to support the use of hearing aids or other rehabilitation options for this unique patient population. This study reveals the critical need for additional research to establish evidence-based practice guidelines that will empower clinicians to provide a high level of clinical care and effective rehabilitation strategies to these patients.
