Published: September 2019

Termoelektrik teknolojisi 19. yüzyıl ortalarından beri biliniyor olmasına karşılık yeterince işlevsel bir kullanım alanına ulaşamamıştır. En yoğun kullanım alanı elektrik üretim alanı değil soğutma alanı olmuştur. Otomobillerde kullanılan küçük buzdolaplarının yapımında, bilgisayar işlemcilerinin soğutulmasında, otomobil egzozlarında oluşan ısıyı elektrik enerjisine dönüştürme amacıyla kullanılmaktadır. Termoelektrik üreteç veya termoelektrik jeneratör ısı enerjisini doğrudan elektrik enerjisine dönüştüren cihazdır. Bu dönüşüme Seebeck etki veya daha genel bir ifade ile termoelektrik etki denir. Yapılan bu çalışmada, termoelektrik dönüştürme elemanlarından oluşan bir termoelektrik jeneratör modül kullanımıyla elektrik enerjisinin elde edilmesi ve bu enerji ile ısıl konfor hedeflenmiştir. Kalorifer radyatörünün ve duvarın yüzey sıcaklığını kullanarak sıcaklık farkı elde edilmiş ve bu sıcaklık farkını elektrik enerjisine dönüştüren termoelektrik jeneratörler ile harici bir kaynağa ihtiyaç kalmadan elektrik enerjisi elde edilmiştir. Üretilen enerjiyi faydalı kullanmak için radyatör kanallarındaki fanlar beslenmiştir. Üretilen enerji ile beslenen fanlar kanallardaki sıcak havayı odaya daha hızlı yayarak oda sıcaklığını daha etkin hale getirmiştir. Sıcaklık farkından, termoelektrik jeneratörler ile oda sıcaklığında 3,24 W güce sahip elektrik enerjisi elde edilmiştir. Üretilen enerjiyi faydalı kullanmak için radyatör kanallarındaki fanlar beslenerek normal oda sıcaklığı 8°C artırılmıştır.

Published: September 2019

Introduction: The aims were to assess residual deltoid ligament instability after lateral malleolus osteosynthesis and to compare the outcomes of deltoid suture and syndesmotic fixation. Methods: A consecutive series of 65 eligible patients with a displaced or minimally displaced fibula fracture identified on a stress radiograph were prospectively enrolled. The patients were randomized into two groups, namely, group I (deltoid repair) and group II (syndesmotic fixation). We assessed the competence of the deltoid ligament intraoperatively using a manual stress test. Only the patients with residual medial instability (Medial Clear Space greater than 4 mm) were randomly assigned for treatment by deltoid ligament repair with anchor or syndesmotic fixation. Results: Of all the patients, 60 (92.2%) had positive preoperative manual stress test results. After fracture osteosynthesis, the test results were still positive in 13 (21.6%) patients, 8 (13.3%) patients from group I, both superficial and deep layers sutured with a bone anchor, and 5 patients (8.3%) from group II, stabilized with a syndesmotic 4-cortical screw. At the end of the surgery, a new manual stress test was performed, which proved stability in all the patients. The average follow-up period was 23.5 months. In groups I and II, the AOFAS scores were 95 and 93, the EQ-5D measures were 0.758 and 0.743, the visual analogue scale (VAS) scores were 16.7 and 19.2, and the Medial Clear Space values were 2.7 ± 0.5 mm and 2.6 ± 0.4 mm, respectively, without statistically significant differences. Conclusion: In 21.6% of cases, residual medial instability persisted after osteosynthesis of the lateral malleolus. The deltoid repair and syndesmotic fixation groups showed similar functional and radiological outcomes. Level of Evidence II; Therapeutic Studies; Prospective Comparative Study.

Energienebenkosten können dabei 75 Prozent des Strompreises ausmachen; Sonderregelungen erschweren jedoch die optimierte Auslegung von Energiesystemen. Vorgestellt wird daher ein Planungstool zum Einsatz von Flexibilitätsmitteln, um Energienebenkosten zu senken. Im Fokus sind dabei Peak Shaving sowie intensive und atypische Netznutzung. Die Auswertung ergab potenziell deutliche Kostenreduktionen.
Microbially Induced Pitting Corrosion on an Austenitic Stainless Steel Pipe
Authors: Strobl S. , Linhardt P. , Haubner R. 
Published: September 2019

Abstract
After only a few weeks of use, leaks caused by pitting corrosion appeared in the weld-affected area of a fire main made of austenitic stainless steel (material number 1.4307). The quality of the used steel was checked and potential reasons for an increased susceptibility of the pipe material to pitting corrosion were searched for by examining samples of pipe sections. For this purpose, metallographic sections were prepared, etched with three different etching solutions (V2A, Beraha 2, Lichtenegger and Blöch), and examined in the light optical microscope.
The examinations revealed a considerable proportion of deformation martensite and a δ-ferrite fraction of about 5 % (mainly in the cross section center) and slip lines in the edge zone. A sensitization of the material in the heat affected zone of a weld could not be observed. Deformation structures and the chromium enrichment in the δ-ferrite promote the propagation of the corrosion processes within the material. However, they cannot be related to the initiation of the pitting corrosion. Heat tinting could be observed in the weld-affected zone, and the chloride content in the water of only about 10 mg/l does not adequately explain the initiation and maintenance of pitting corrosion processes (additionally confirmed by an electrochemical examination).
However, during the pipe surface examination, small black spots could also be observed on the unaffected surface. EDS analysis in the SEM and wet chemical methods identified them as microscopic manganese dioxide nodules. These deposits are an indication of microbially induced corrosion during which the microbially formed manganese dioxide, being a strong oxidant, significantly increases the stainless steel sensitivity to chloride. In the present case, this finding could be confirmed by measuring the free corrosion potential. In addition to that, indications were found suggesting that the pipe was temporarily charged with water having a higher chloride content, plausibly explaining the initiation of the pitting corrosion. The operating conditions of this pipe are characterized by stagnating water which strongly promotes the stabilization of pitting corrosion and thus represents an additional aggravating factor.

Published: September 2019

O exame completo e exato do sistema genital é de fundamental importância para o diagnóstico e tratamento das afecções reprodutivas. Além disso, o exame ginecológico tem por finalidade detectar a fase do ciclo estral, a gestação e causas da infertilidade da fêmea. O exame andrológico é realizado para atestar o potencial reprodutivo do macho, além de diagnosticar as causas da impotência coeundi e generandi. O exame ginecológico se inicia com a anamnese, seguida pelo exame clínico geral, exame específico externo ( avaliação da vulva e vestíbulo) e exame interno (palpação retal de cérvix, útero e ovários em grandes animais e vaginoscopia) . Os exames complementares são de grande auxílio para o diagnóstico, e consistem em ultrasonografia de útero e ovários, citologia vaginal em pequenos animais, exame histológico, microbiológico, testes sorológicos e dosagens hormonais. A anamnese e o exame clínico geral também são as primeiras etapas do exame andrológico, seguido de exame específico do sistema reprodutor externo (inspeção e palpação de escroto, testículos, epidídimo, funículo espermático e medição da circunferência escrotal) e interno ( palpação retal das glândulas anexas), teste de libido, espermograma e por fim exames complementares como ultrassonografia de glândulas anexas e testículos, sorologia, PCR, testes hormonais, exame microbiológico do sêmen além de testes funcionais dos espermatozóides.
