When mouse spermatozoa swim in media of high viscosity, additional waves of bending are superimposed on the primary traveling wave. The additional (secondary) waves are relatively small in scale and high in frequency. They originate in the proximal part of the interbend regions. The initiation of secondary bending happens only in distal parts of the flagellum. The secondary waves propagate alon...

This paper presents a study on the flexural behaviour of hybrid composite pipes reinforced with carbon and glass fibres. The progressive failure in three point bending was modelled numerically by Finite Element Analysis (FEA). FEA based model validated against experimental data. With this developed model, effects ply angle, fibre volume fraction hybridisation have been found. It is shown from r...

BACKGROUND Endometriosis is a chronic and progressive condition of women of reproductive age. It is strongly associated with significant impairment of sexual function. AIM To objectively evaluate the impact of laparoscopic excision of endometriosis on sexual function in patients with deep infiltrating endometriosis (DIE) compared to healthy women. SETTING AND DESIGN Prospective study, inclu...

Recent clinical trials indicate that approximately two-thirds of patients in New York Heart Association (NYHA) class II and III, who comprise almost 90% of patients with heart failure, die suddenly. Patients in NYHA class IV usually die of progressive heart failure. Implantation of implantable cardioverters defibrillators (ICDs) in this population would represent a huge logistic problem and eco...

In the SOD transgenic ALS mouse model, motoneuron death has not been reported earlier than 90 days of age, the so-called pre-symptomatic phase. We recorded contractile force from the fast-twitch medial gastrocnemius and slow-twitch soleus muscles and their constituent motor units to determine the number of intact motor units during the asymptomatic phase of disease. We found an early, selective...

Feature descriptors have enabled feature matching under varying imaging conditions, while mostly being backed by experimental evidence. In addition to imposing some restrictions in imaging conditions needed to ensure matching, extending the existing descriptors is not straightforward due to the lack of sound mathematical bases. In this work, by using a surface bending versus shape histogram bas...

Usually, fatigue tests on fibre-reinforced composites are performed in uni-axial tension/tension or tension/compression fatigue [1], providing the S-N data. Although bending fatigue tests are not widely accepted as a standard, they are used a lot for research purposes [2] and they do have some important advantages [3]. In case of three-point bending fatigue, the history of bending force versus ...

This work introduces an Abaqus CAE simulation model and its validation for freeform bending with movable die, which is extended in the of a weld seam longitudinally welded tube. The superordinate goal development soft sensor, that can derive mechanical properties bent tube as basis closed-loop control. To guarantee close monitoring properties, sensor needs to be able extrapolate spatially. Beca...

Rett syndrome (RTT) is a severe neurodevelopmental disorder and is the second most common form of severe mental retardation in females. RTT affects 1 in 8,000 births by the age of 15 and does not discriminate between racial or ethnic groups. It is a devastating condition characterised by progressive loss of speech and movement and the development of intellectual disability at a very young age. ...

Following excision of Bi 6 melanoma isografts from C57BL/ 6J mice, 80 to i 00% of untreated animals develop progressive pulmonary metastases after 4 to 6 weeks and die within 100 days. Immune RNA (1-ANA)extracted from the lymphoid tissues of guinea pigs immunized with Bi 6 melanoma or antigenically distinct syngeneic Lewis lung carcinoma was incubated in vitro with splenocytes harvested from no...
