Ultraschall in der Diagnostik peripherer Nervenl sionen
Peer S
Journal für Neurologie, Neurochirurgie und Psychiatrie , 2009,
Abstract: Die Anwendung der Sonographie für die Untersuchung von Erkrankungen des peripheren Nervs hat in den letzten Jahren deutlich zugenommen. Durch hohe Detailaufl sung, Interaktivit t und zuverl ssige Ergebnisse bietet sich die Sonographie geradezu als ideale Methode für die Abkl rung einer Vielzahl von Pathologien des peripheren Nervs an: Nicht nur Kompressionssyndrome, sondern auch traumatische L sionen, Tumoren und Entzündungen des peripheren Nervs k nnen mit hoher diagnostischer Sicherheit dargestellt werden. Daneben besteht die M glichkeit, die Sonographie zur Steuerung der Regionalan sthesie, von Biopsien oder therapeutischen Instillationen einzusetzen. In dieser Arbeit wird eine übersicht über den derzeitigen Stand der Sonographie des peripheren Nervensystems gegeben.
Radiologischer Follow-up nach chirurgischer Behandlung der morbiden Adipositas
Peer S,Gruber I,Peer R
Journal für Gastroenterologische und Hepatologische Erkrankungen , 2007,
Abstract: Die morbide Adipositas ist nicht nur in den USA, sondern auch in Europa zu einem wichtigen Gesundheitsproblem geworden, und chirurgische Verfahren wie Gastric Banding oder Magenbypass nehmen inzwischen einen hohen Stellenwert in der Therapie dieser Erkrankung ein. Für den Kliniker, aber vor allem auch für den Radiologen ist daher die Kenntnis der g ngigen Verfahren, des typischen postoperativen Verlaufs, aber auch der m glichen Komplikationen und deren Diagnose mit bildgebenden Verfahren unumg nglich. Nachfolgend werden die radiologischen Methoden für die Abkl rung vor und nach chirurgischen Eingriffen zur Gewichtsreduktion erl utert und Beispiele für die klassischen Komplikationen pr sentiert.
Do South African universities provide the required training platforms for otolaryngology specialist training?
S Peer, J Fagan
South African Medical Journal , 2012,
Abstract: Background. Concern exists about the quality of specialist training platforms at South African universities and teaching hospitals. Method. We conducted an audit of the quality of training at South African otolaryngology (ENT) training institutions from the perspective of the registrars. Results. Some institutions were deficient in terms of supervision, theatre time, access to teaching aids and research tools, and range of surgery, and do not provide the required training platforms for ENT specialist training. Five out of 8 institutions have produced <2 publications in peer-reviewed journals over the past 5 years. Conclusions. The HPCSA fails to adequately police the quality of training in South Africa. Training programme shortcomings must urgently be addressed to ensure proper education and training of otolaryngologists.

Fistuloclysis - a valuable option for a difficult problem
S Peer, MS Moodley, HM Cassimjee, BM Singh
South African Journal of Surgery , 2008,
Abstract: Despite the great advances in the management of highoutput enterocutaneous fistulas (HOECFs), this condition remains a challenge for surgeons in both the developing and developed worlds. Since the early 1960s, nutritional support has been the mainstay of management that expedites the spontaneous healing of the fistula or, if healing does not occur, ensures that the patient is nutritionally optimised for surgical reconstruction.

Late reproductive senescence in a rabbit line hyper selected for reproductive longevity, and its association with body reserves
Theilgaard Per,Sánchez Juan,Pascual Juan,Berg Peer
Genetics Selection Evolution , 2007, DOI: 10.1186/1297-9686-39-2-207
Abstract: The aim of the present study was to investigate differences in reproductive and body traits during successive parities between two genetic lines. The LP line was constituted by means of selection of animals having an extremely high number of parities (at least 25) and an average reproductive performance compared to the V line selected for litter size at weaning during 31 generations. The two lines were found to have an equal reproductive performance in the first three parities, but the LP line had higher reproductive performance from the fourth parturition onwards. The low reproductive performance after the third parity in the V line was suggested to be caused by constrained environmental conditions in the test station. A line by parity interaction was also observed for body weight, since body weight declined going from the third to the fourth parity in the LP line but not the V line. Thus, it was concluded that hyper selection for reproductive longevity and average prolificacy successfully delayed reproductive senescence, and that this newly founded line showed less environmental sensitivity, which might have been mediated by a higher body reserve.
Genetic Algorithm for Concurrent Balancing of Mixed-Model Assembly Lines with Original Task Times of Models  [PDF]
Panneerselvam Sivasankaran, Peer Mohamed Shahabudeen
Intelligent Information Management (IIM) , 2013, DOI: 10.4236/iim.2013.53009
Abstract:

The growing global competition compels manufacturing organizations to engage themselves in all productivity improvement activities. In this direction, the consideration of mixed-model assembly line balancing problem and implementing in industries plays a major role in improving organizational productivity. In this paper, the mixed model assembly line balancing problem with deterministic task times is considered. The authors made an attempt to develop a genetic algorithm for realistic design of the mixed-model assembly line balancing problem. The design is made using the originnal task times of the models, which is a realistic approach. Then, it is compared with the generally perceived design of the mixed-model assembly line balancing problem.

Design and Comparison of Genetic Algorithms for Mixed-Model Assembly Line Balancing Problem with Original Task Times of Models  [PDF]

American Journal of Industrial and Business Management (AJIBM) , 2016, DOI: 10.4236/ajibm.2016.65063
Abstract: Assembly line balancing is a key for organizational productivity in terms of reduced number of workstations for a given production volume per shift. Mixed-model assembly line balancing is a reality in many organizations. The mixed-model assembly line balancing problem comes under combinatorial category. So, in this paper, an attempt has been made to develop three genetic algorithms for the mixed-model assembly line balancing problem such that the combined balancing efficiency is maximized, where the combined balancing efficiency is the average of the balancing efficiencies of the individual models. At the end, these three algorithms and another algorithm in literature are compared in terms of balancing efficiency using a randomly generated set of problems through a complete factorial experiment, in which “Algorithm”, “Problem Size” and “Cycle Time” are used as factors with two replications under each of the experimental combinations to draw inferences and to identify the best of the four algorithms. Then, through another set of randomly generated small and medium size data, the results of the best algorithm are compared with the optimal results obtained using a mathematical model. It is found that best algorithm gives the optimal solution for all the problems in the second set of data, except for one problem which cannot be solved using the model. This observation supports the fact that the best algorithm identified in this paper gives superior results.
Heuristics for Mixed Model Assembly Line Balancing Problem with Sequencing  [PDF]
Panneerselvam Sivasankaran, Peer Mohamed Shahabudeen
Intelligent Information Management (IIM) , 2016, DOI: 10.4236/iim.2016.83005
Abstract: The growing global competition compels organizations to use many productivity improvement techniques. In this direction, assembly line balancing helps an organization to design its assembly line such that its balancing efficiency is maximized. If the organization assembles more than one model in the same line, then the objective is to maximize the average balancing efficiency of the models of the mixed model assembly line balancing problem. Maximization of average balancing efficiency of the models along with minimization of makespan of sequencing models forms a multi-objective function. This is a realistic objective function which combines the balancing efficiency and makespan. This assembly line balancing problem with multi-objective comes under combinatorial category. Hence, development of meta-heuristic is inevitable. In this paper, an attempt has been made to develop three genetic algorithms for the mixed model assembly line balancing problem such that the average balancing efficiency of the model is maximized and the makespan of sequencing the models is minimized. Finally, these three algorithms and another algorithm in literature modified to solve the mixed-model assembly line balancing problem are compared in terms of the stated multi-objective function using a randomly generated set of problems through a complete factorial experiment.
