Increasing clavulanic acid production both in wild type and industrial streptomyces clavuligerus strains by amplification of positive regulator claR gene
Mutlu, Alper; Özcengiz, Gülay; Department of Biology (2012)
Streptomyces clavuligerus is a Gram-positive, filamentous bacterium which produces several important secondary metabolites, including isopenicillin N, cephamycin C and the β-lactamase inhibitor clavulanic acid. Among these compounds, clavulanic acid is being used in combination with commonly used β-lactam antibiotics in order to fight against bacterial infections that are resistant to such antibiotics. Among these combinations, Augmentin, composed of amoxicillin and clavulanic acid, is the most widely presc...
The effects of positive core self and external evaluations on performance appraisals
Güven, Lale; Sümer, Canan H; Department of Industrial and Organizational Psychology (2007)
The purpose of this study was to investigate the effects of core self-evaluations (CSEs) and core external-evaluations (CEEs) on performance evaluations. It was hypothesized that people with higher levels of CSEs and CEEs would be more lenient in their performance ratings, when rating neutral performance. The second hypothesis of the study was that people with higher and lower CSEs would engage more in halo when rating neutral performance compared to people with average levels of CSEs. It was further hypoth...
Transfer functions with positive impulse response: Feedback controller design and application to cooperative adaptive cruise control
İşler, İbrahim Tayyip; Schmidt, Klaus Verner; Department of Electrical and Electronics Engineering (2021-9-7)
Driver assistance systems are increasingly employed to replace human driver functionality. Cooperative adaptive cruise control (CACC) automates the longitudinal vehicle motion to support safe vehicle following using distance measurements and state information communicated among vehicles. A basic requirement when using CACC is to attenuate fluctuations along vehicle strings, which is captured by the formal condition of string stability. Hereby, different notions of string stability exist in the literature ba...
Dispositional affectivity and job performance : mediating effects of job satisfaction
Öz, Bahar; Sümer, Hayriye Canan; Department of Psychology (2003)
In the present study, the relationship between dispositional affectivity and job performance was investigated under the potential mediating effects of job satisfaction. The study was conducted in three phases. In Phase I, the scale development phase, an assistant evaluation form (AEF) was developed by collecting job analytic information from 35 Teaching Assistants (TAs) and critical incidents from 38 faculty members from a wide range of departments in Middle East Technical University (METU). In the second p...
Performance evaluation and cfd analysis of a positive displacement diaphragm pump
Gökçe, Gökay; Albayrak, Kahraman; Department of Mechanical Engineering (2011)
In order to understand flow characteristics inside a positive displacement pump, every point in the flow field must be carefully observed. Such observations are difficult, expensive and usually time consuming to achieve with physical testing. During tests one can observe flow characteristics only at the locations where the instrument device is attached, not the whole flow domain. This thesis mainly focuses on the evaluation of design and performance characteristics of a positive displacement triplex diaphra...
