The frame surrounds the two first anchors, and each of the elastic members connects the corresponding first anchor and the frame. Each of the first anchors is disposed near the center of the MEMS apparatus to decrease an effect caused by warpage of the substrate. The MEMS apparatus can be applied to an MEMS sensor having a rotatable mass, such as a three-axis accelerometer or a magnetometer, to improve process yield, reliability, and measurement accuracy.

Method and apparatus for lamination of substrates, e.g. rigid plastic layers, to manufacture laminated products. The methods include the sequential application of vacuum and mechanical force through a two-stroke process performed by a lamination apparatus having one or more force-producing stroke cylinders. Actuation of a cylinder to produce a first stroke creates a sealed chamber within the apparatus, enclosing a stack of substrates to be laminated. The sealed chamber may be evacuated of air by application of a vacuum. Subsequent actuation of a cylinder to produce a second stroke applies mechanical force to the sealed chamber, which compresses the substrates into a laminated product substantially free of air bubbles or voids.

Bronchiolitis is one of the most common infectious respiratory conditions of early childhood, and most children have a mild clinical course. Unfortunately, the small subgroup of children requiring continuous positive airway pressure and/or intubation remains ill-defined.

In children with bronchiolitis, we found several demographic, historical, and clinical factors that predicted the need for mechanical respiratory support including in utero smoke exposure. We also found a novel subgroup of children with bronchiolitis who have a rapid respiratory decline. (Read the full article)

Advances in the treatment of critically ill infants have increased survival of extremely low/very low birth weight and medically complex infants. Improved survival can result in prolonged mechanical ventilation and sometimes tracheostomy. Current tracheostomy rates for these infants are unknown.

This long-term review of infants discharged from a NICU with tracheostomies is the first to describe tracheostomy rates specifically in extremely low/very low birth weight infants. It focuses on long-term clinical outcomes and comorbidities rather than surgical complications. (Read the full article)

In order to establish sustainable heat loading (heat removal and storage) in abandoned flooded mine workings it is important to understand the geomechanical impact of the cyclical heat loading caused by fluid injection and extraction. This is particularly important where significantly more thermal loading is planned than naturally occurs. A simple calculation shows that the sustainable geothermal heat flux from abandoned coal mines can provide less than a tenth of Scotland's annual domestic heating demand. Any heat removal greater than the natural heat flux will lead to heat mining unless heat storage options are also considered.

As a first step, a steady-state, fully saturated, 2D coupled hydromechanical model of a generalized section of pillar-and-stall workings has been created. Mine water rebound was modelled by increasing the hydrostatic pressure sequentially, in line with monitored mine water-level data from Midlothian, Scotland. The modelled uplift to water-level rise ratio of 1.4 mm m^–1 is of the same order of magnitude (1 mm m^–1) as that observed through interferometric synthetic aperture radar (InSAR) data in the coalfield due to mine water rebound. The modelled magnitude of shear stress at the pillar corners, as a result of horizontal and vertical displacement, is shown to increase linearly with water level. Mine heat systems are expected to cause smaller changes in pressure than those modelled but the results provide initial implications on the potential geomechanical impacts of mine water heat schemes which abstract or inject water and heat into pillar-and-stall coal mine workings.

Fish scales serve as a dermal armor that provides protection from physical injury. Due to a number of outstanding properties, fish scales are inspiring new concepts for layered engineered materials and next-generation flexible armors. While past efforts have primarily focused on the structure and mechanical behavior of ontogenetic scales, the structure-property relationships of regenerated scales have received limited attention. In the present study, common carp (Cyprinus carpio) acquired from the wild were held live in an aquatic laboratory at 10° and 20°C. Ontogenetic scales were extracted from the fish for analysis, as well as regenerated scales after approximately 1 year of development and growth. Their microstructure was characterized using microscopy and Raman spectroscopy, and the mechanical properties were evaluated in uniaxial tension to failure under hydrated conditions. The strength, strain to fracture and toughness of the regenerated scales were significantly lower than those of ontogenetic scales from the same fish, regardless of the water temperature. Scales that regenerated at 20°C exhibited significantly higher strength, strain to fracture and toughness than those regenerated at 10°C. The regenerated scales exhibited a highly mineralized outer layer, but no distinct limiting layer or external elasmodine; they also possessed a significantly lower number of plies in the basal layer than in the ontogenetic scales. The results suggest that a mineralized layer develops preferentially during scale regeneration with the topology needed for protection, prior to the development of other qualities.

BACKGROUND:Assisted coughing via mechanical in-exsufflation (MI-E) is a first-line treatment for secretion management in patients with amyotrophic lateral sclerosis (ALS) with unassisted CPF < 4.25 L/s. Some devices enable oscillations to be added to MI-E (MI-E+O). We sought to determine whether adding oscillations to MI-E enables a reduction in the use of invasive secretion management procedures (ie, bronchoscopy or tracheostomy) in subjects with ALS.METHODS:We conducted a 12-month, prospective, randomized follow-up study of subjects with ALS for whom assisted coughing techniques were indicated. One group was treated with oscillations in addition to MI-E (MI-E+O), and the other group was treated with conventional MI-E.RESULTS:29 subjects were included in the MI-E group and 27 subjects were included in the MI-E+O group. Five subjects (8.9%) required invasive techniques for secretion management (3 in the MI-E group and 2 in the MI-E+O group, P = .70). Treatment with MI-E+O did not alter the risk of invasive procedures (odds ratio 0.69, 95% CI 0.10–4.50, P = .70). The mean number of respiratory infections was 0.58 ± 0.16 in the MI-E group and 0.025 ± 0.08 in the MI-E+O group (P = .10). Survival was 8.96 ± 0.18 months in the MI-E group and 7.70 ± 0.70 months in the MI-E+O group (P = .10).CONCLUSION:Adding oscillations to MI-E did not enable a reduction in the need to perform invasive procedures for secretion management in subjects with ALS.
