In the actuarial literature, several exact and approximative recursive methods have been proposed for calculating the distribution of a sum of mutually independent compound Bernoulli distributed random variables. In this paper, we give an overview of these methods. We compare their performance with the straight- forward convolution technique by counting the number of dot operations involved in each method. It turns out that in many practicle situations, the recursive methods outperform the convolution method.

This study aims to assess the impact of monospecific Tectona grandis forest plantation on the soil mite abundance and diversity. To achieve these objectives, two sites situated in Ivory Coast were investigated. The first, a primary forest was characterized by a very weak human activities whereas the second, a teak plantation was characterized by a high disturbance performed during the planting. After extracting, sorted and description, 116 mite species were described in the two sites. Mite densities were lower in teak plantation and also higher in the litter and decreased to the depth in both sites. Species richness re- corded in teak plantation （52 species） was significantly lower compared to primary forest （98 species）. The same trend was ob- served for oribatida but not for Gamasida. The lower oribatida （5 vs. 17） and higher oribatida （24 vs. 41） were recorded respec- tively in teak plantation and primary forest. Mite Shannon index and evenness were significantly different between sites. High Jaccard index values and the appearance of exclusive species in both habitats showed that the sites are very distinct. Total number of species recorded corresponded to 58%-63% of the total number of species estimated by ACE and Chao 1＆2 estimators, indi- cating that the sampling effort was not sufficient. Mite abundance and diversity varied depending on the characteristics of habi- tats. Chemical element （Corn, Ctot, Ntot, and SoM） values were lower in teak plantation （disturbed habitat） and significantly dif- ferent to primary forest in the topsoil. Apart from litter height, soil depth, pH and C/N ratio, others variables were strongly corre- lated to mite abundance and diversity [Current Zoology 59 （5）： 633-643, 2013].

The present paper reports on extensive investigations using an ultrasomc treatment ot WAS, to study its potential to meet one or all of four objectives：（1） reduce WAS quantities; （2） achieve a better dewaterability; （3） provoke a release of CoD from the biosolids, preferably transformed into biodegradable organics and （4） possibly destroy the filamentous micro-organisms responsible for sludge bulking. The experiments are carried out in a batch reactor of volume up to 2.3L. The ultrasonic apparatus consisted of a generator, a converter and a sonotrode, supplied by Alpha Ultrasonics under the brand name of Telsonic. Three different sludge kinds were tested, at approximate concentration （DS/WAS） between 3.5 and 20g·L^-1. The release of CoD from the WAS-phase into the filtrate phase is a function of the specific energy-input SE with yields of about 30% achievable at SE-values of 30000 kJ·kg^-1. A major fraction of the CoD is transformed into biodegradable organics （BoD）. The reduction of DS-fraction of the sludge is equivalent to the CoD-release rates. Although the dry solids content （DS） is reduced, the dewaterability of the sludge is not improved. This reflects itself in a slightly decreased dryness of the filter cake using vacuum filtration, and in increased values of the capillary suction time （CST）. This more difficult dewaterability is the result of considerably reduced floc sizes, offering an extended surface area. More surface water is bound （CST increases） and the filterability decreases due to clogging of the cake. To reach the same dryness as the untreated cake, the required dosage of poly-electrolyte increases proportionally with the level of ultrasound energy supplied. The ultrasonic reduction of filamentous WAS organisms is not conclusive and very little effect is seen at low intensities and short treatment durations. Microscopic analysis of the WAS identified the dominant presence of Actynomyces. Especially the release of CoD and its transformation into

Artificial vessel grafts are used for outflow reconstruction in living donor liver transplantation (LDLT). We report a very rare case of invasion of an artificial vascular graft into the duodenal bulb after LDLT. A 54-year-old man underwent LDLT in August 2012. A right hemiliver without a middle hepatic vein was used as a graft. The outflow of segment V was created by anatomizing an artificial graft to the inferior vena cava. During outpatient follow-up, the patient complained of acid regurgitation but did not experience abdominal pain. Panendoscopy was arranged and it revealed that the artificial graft had invaded the duodenal bulb. operation was performed to remove the graft and the patient discharged after fourteen days of hospital stay. Invasion of artificial vascular grafts to adjacent organs is rare, but happens in living donor liver transplantation. It may be caused by inappropriate vessel graft length and adhesion between the graft and adjacent organs.

We investigate the hydrodynamic interactions of spherical colloidal nano particles and nano tetrahedra near a planar wall by means of molecular dynamics(MD)simulations of rigid particles within an all-atom *** both spherical and nano-tetrahedral particles,we find that the parallel and perpendicular components of the local diffusion coefficient and viscosity,show good agreement with hydrodynamic theory of Fax´en and *** provides further evidence that low perturbations from sphericality of a nanoparticle’s shape has little influence on its local diffusive behaviour,and that for this particular case,the continuum theory fluid dynamics is valid even down to molecular scales.
