[en] A huge mesenteric cyst in a 61-year-old female was treated by percutaneous ablation using ethanol. Marked shrinkage was achieved and regrowth was not seen 16 months after ablation. Resection is the standard therapy for mesenteric cysts, but it may be valuable to discuss the feasibility of percutaneous ablation before resection if the lesion wall is smooth and thin, and if solid nodules are not depicted on imaging.

[en] Highlights: • Shrinkage of concrete is measured with various temperature and humidity conditions. • The fib MC2010 shrinkage model is accurate for low RH and high T conditions. • The fib MC2010 shrinkage model slightly underestimate for other conditions. • The fib MC2010 creep model conservatively predicts creep strains. - Abstract: Creep and shrinkage of concrete is influenced by many factors including relative humidity and temperature. The combined effect of low relative humidity (<20%) and high temperature (38 °C) on creep and shrinkage of concrete is uncertain as limited tests have been conducted in this domain. Also unknown is the ability of the fib MC2010 model code in predicting the shrinkage and creep at the environment. This paper presents the results of experiments conducted in which concrete was cast and exposed to the aforementioned environmental conditions. The shrinkage and creep behaviour of the concrete was observed for 110 days, and experimental results were compared with predicted values using fib MC2010 model code.

[en] Shrinkage is one of the most important defects in polymeric parts. Although there are several studies in order to control and reduce the shrinkage of polymeric parts, there is no systematic investigation on the shrinkage of injection molded polycarbonate (PC) parts. Therefore, the comprehensive investigation of the shrinkage behavior of PC parts was conducted in the present study. Response surface methodology (RSM) was utilized and PC samples were injection molded in different conditions based on the design of experiments. The shrinkage was studied in both longitudinal and latitudinal directions. The measurements were performed at five points in latitudinal and three points in longitudinal. The shrinkage behavior respect to the distance from the gate was studied. A comparative analysis between the shrinkage across and along the injection direction was performed. Analysis of variance tool of RSM method was utilized in order to recognize most effective parameters on the volumetric shrinkage. A regression model was proposed to estimate the volumetric shrinkage of the PC with high accuracy. The interaction effect of parameters on the volumetric shrinkage was analyzed and different solutions to control the shrinkage were recognized. (paper)

[en] Activated sintering of high-refractory non-oxide compounds, under the influence of various physical and chemical factors on the shrinkage kinetics, was described. The sintering process was presented as a chemical reaction, but the degree of activation was determined quantitatively taking into account the change in temperature adequate to the maximum shrinkage rate during heating at a constant rate or the change in the order of reaction during isothermal sintering. It was found out that activation characterized the initial stage and that it was caused either by changes in dispersion of powders, or by the heating rate up to the isothermal temperature, or by additives, or by the influence of the atmosphere or the vacuum. The influence of ultrasonic vibrations on the shrinkage kinetics was examined. In the initial sintering stage ultrasonic vibrations activate the process, but during a long-lasting influence, they disactivate it, causing decay of the structure

[en] Insulinoma is a rare neuroendocrine tumor, most commonly originating from the pancreas, which is either sporadic or familial as a component of multiple endocrine neoplasia type 1 syndrome (MEN1). It is characterized by increased insulin secretion leading to hypoglycemia. Surgical removal is considered the treatment of choice, with limited side effects and relatively low morbidity and mortality, both being improved by the laparoscopic procedure. We present the case of a 30-year-old patient with MEN1 and recurrent insulinoma with severe hypoglycemic episodes who could not be surgically treated due to the adherence of the tumor to large blood vessels and to prior multiple surgical operations. He was treated by repeated embolization using spherical polyvinyl alcohol particles, resulting in shrinkage of the tumor, improvement of the frequency and severity of the hypoglycemic episodes, and better quality of life.

[en] A method of treating a wool textile for imparting shrink-resistant properties is described comprising applying to the textile ionising radiation and a polymer resin selected such that the resin will be bonded onto the wool fibres and form a relatively thin application thereon for imparting shrink-resistant properties, the process being carried out substantially at ambient temperature

[en] Recently, there are many fields have been required for the precision measurements, as an advanced example of which, a precise change of inner structure during the hydration process of mortar was observed by ultrasonic and dielectric measurements. The results show that it is possible to determine the safety of mortar and mixing ratio, and strength growth and shrinkage rate by heat evolution

[en] The objectives of this presentation are to understand soil swelling and shrinkage mechanisms, and the development of desiccation cracks, to distinguish between soils having different magnitude of swelling, as well as the consequences on soil structural behaviour, to know methods to characterize soil swell/shrink potential and to construct soil shrinkage curves, and derive shrinkage indices, as well to apply them to assess soil management effects

[en] Two types of directed self-avoiding walks (SAW's), namely, three-choice directed SAW and outwardly directed SAW, have been studied on infinite percolation clusters on the square lattice in two dimensions. The walks on the percolation clusters are generated via a Monte Carlo technique. The longitudinal extension R_N and the transverse fluctuation W_N have been measured as a function of the number of steps N. Slight swelling is observed in the longitudinal direction on the random lattices. A crossover from shrinking to swelling of the transverse fluctuations is found at a certain length N_c of the walks. The exponents related to the transverse fluctuations are seen to be unchanged in the random media even as the percolation threshold is reached. The scaling function form of the extensions are verified

[en] Shrinkage and whitening of the anterior capsule opening - capsular contraction syndrome - is a well-known complication after continuous curvilinear capsulorrhexis. A 72-year-old women underwent continuous curvilinear capsulorrhexis, phacoemulsification, and implantation of posterior chamber intraocular lens with polymethylmethacrylate haptics. Four months postoperatively, the patient reported deterioration in visual acuity that was resulted due to complete occlusion of anterior capsular opening by fibrotic tissue. The fibrous membrane was excised surgically in capsulorrhexis fashion. (author)
