Article Abstract
Objective: To evaluate medical efficacy and safety of crestal, minimally invasive sinus floor augmentation (MISFA) using an innovative method based on high hydraulic pressure.
Study Design: Twenty MISFA using the novel Jeder-System were performed in 18 patients at 2 study sites in Vienna, Austria. The Jeder-System consists of the Jeder-drill, the Jeder-pump, and a connecting tube-set. The pump generates high hydraulic pressure (1.5 bar) pushing back the sinus membrane from the drill at the first perforation. The pump also monitors the whole procedure by constantly measuring pressure and volume.
Results: Five percent membrane perforation rate (1/20) only detected in the postoperative computed tomography scan and without implication for implant placement. Height gain of 9.2 ± 1.7 mm achieved (from 4.6 ± 1.4 mm to 13.8 ± 2.3 mm). Average patient satisfaction was 9.82 on scale from 1 to 10 (10 = very satisfied). Mean duration of sick leave was 0.19 days. 18-month survival rate was 95% (1/20 implant lost).
Conclusions: Within the limits of a prospective open cohort study with 20 cases, our data demonstrate the safety and medical efficacy of the novel method.

Spillway chutes are critical in dam flood control, particularly in high dams where high water heads and large discharge in narrow canyons amplify the demand for safe discharging. For large unit discharges in spillways, aeration protection is essential to prevent cavitation erosion, but challenges arise from air duct choking in the traditional spillway and nonaerated regions in the stepped spillway. This paper introduces a novel spillway called the pre-aerated stilling basin spillway (PSBS).

Populus tree species are commonly used for creating shelter forests in vast areas of northern China, at least partially due to their fast growth. However, they are facing severe problems of decline and mortality caused by drought. In contrast, tree species native to water-limited environments usually have slow growth and are currently not commonly used in afforestation, while these species are gaining more attention in forestry for their greater resilience to drought.

Helical carbon nanotubes (HCNTs) with different geometrical properties were constructed and incorporated into nanocomposites for the investigation of the anti-crack mechanism. The interfacial mechanical properties of the nanocomposites reinforced with straight carbon nanotubes and various types of HCNTs were investigated through the pullout of HCNTs in the crack propagation using molecular dynamics (MD). The results show that the pullout force of HCNTs is much higher than that of CNTs because the physical interlock between HCNTs and matrices is much stronger than the van der Waals (vdW) interactions between CNTs and matrices.

Phosphorus (P) and potassium (K) play important roles in plant metabolism and hydraulic balance, respectively, while calcium (Ca) and magnesium (Mg) are important components of cell walls. Although significant amounts of these nutrients are found in wood, relatively little is known on how the wood concentrations of these nutrients are related to other wood traits, or on the factors driving the resorption of these nutrients within stems. We measured wood nutrient (i.

The performance of Upflow Anaerobic Sludge Blanket (UASB) bioreactors treating sulfate (SO) -rich effluents depends on multiple factors, including microbial interactions and operational conditions. The high complexity of these systems necessitates the use of mathematical modelling tools to better understand the process and predict the long-term impacts of various operational variables. In this work, a mathematical model describing the long-term operation of a sulfate-fed 2.
