The initial weight and volume relationships are crucial factors in determining the strength, stiffness, durability of cement-stabilized soils. porosity/binder ratio has been widely used as a control parameter for stabilized soil mixtures. However, this approach does not take into consideration water content during stabilization process, which can impact strength final product. To address issue,...

Waste incineration air pollution control (APC) residues require pretreatment before landfilling because these types of encompass pollutants from an gas stream. The environmental concerns APC consist a risk leaching and subsequent release potentially harmful substances that occur under exposure. stabilization/solidification (S/S) method is one the most applied technologies for hazardous residues...

STUDY DESIGN A prospective consecutive cohort study (follow-up study). OBJECTIVE Our study investigated whether implantation of an expandable titanium mesh cage (Osseofix®) is a successful and safe minimally invasive therapy for osteoporotic vertebral compression fractures (VCF). Our experiences, clinical and radiological findings after 12 months follow-up are presented. Kypho- and vertebropl...

Abstrak Perbaikan lempung dengan semen, kapur, dan abu sekam (RHA) terbukti meningkatkan kuat geser daya dukung. Kandungan silika kayu (ASK) hampir sama RHA. Penelitian melihat pengaruh ASK pada terstabilisasi semen kapur. Pengujian Tekan bebas (UCS) dilakukan untuk membandingkan nilai tekan (qu) asli, distabilisasi kombinasi kapur dan/atau ASK. Sampel diuji empat kondisi. Hasil UCS tanpa pemer...

BACKGROUND The treatment of unstable thoracolumbar burst fractures with short-segment posterior spinal instrumentation without anterior column reconstruction is associated with a high rate of screw breakage and progressive loss of reduction. The purpose of the present study was to evaluate the functional, neurologic, and radiographic results following transpedicular, balloon-assisted fracture r...

BACKGROUND Despite the known demographic shift with expected doubled rate of vertebral body fractures by the year 2050, a standardized treatment concept for traumatic and osteoporotic incomplete burst fracture of the truncal spine does not exist. This study aims to determine whether minimally invasive fracture care for incomplete osteoporotic thoracolumbar burst fractures using intravertebral e...

STUDY DESIGN Case report. OBJECTIVE The aim of this work is to describe a case of infected vertebroplasty due to uncommon bacteria solved surgically with 2 years of follow-up and to discuss 6 other cases found in literature. SUMMARY OF BACKGROUND DATA Vertebroplasty is a well-known and useful technique for the treatment of painful osteoporotic vertebral fractures. Complications, such as cor...

With currently available therapies, full regeneration of lost periodontal tissues after periodontitis cannot be achieved. In this study, a combined compartmentalized system was tested, composed of (a) a platelet lysate (PL)-based construct, which was placed along the root aiming to regenerate the root cementum and periodontal ligament, and (b) a calcium phosphate cement composite incorporated w...

The cement gland is a simple secretory organ that marks the anterior-most dorsal ectoderm in Xenopus embryos. In this study, we examine the timing of cement gland induction and the cell interactions that contribute to cement gland formation. Firstly, we show that the outer ectodermal layer, from which the cement gland arises, becomes specified as cement gland by mid-gastrula. Curiously, at earl...

The use of regenerated activated carbon as an immobilizing additive for phenol in solidification/stabilization (S/S) processes was investigated. The adsorption capacity of regenerated carbon was compared to that of the virgin form and was found to be very close. The effects of pH and Ca(OH)(2) concentration within the S/S monolith on the adsorption process were also examined. Kinetic tests were...
