Successful pig farming needs the best conditions of cleanliness in the housings. The present study examined for the first time whether a robot scraper usually applied in dairy farming is usable in sow housings for cleaning the slatted floors and improving hygiene and thus animal welfare. For evaluating the suitability of the robot scraper with regard to the cleaning performance (polluted surface area and occluded slots), the whole housing area was divided into score-squares, which were individually scored at defined intervals. Selected excrement quantities removed by the robot were weighed. In order to assess the animals’ interactions with the robot scraper, their behaviour towards the device was observed. Although the faeces of pigs had a firmer consistency than bovine excrement, excrement quantities of up to 1.4 kg m−2 were almost completely removed. Even 6 h after the cleaning its effect was still visible. Dry-cleaning led faster to nonslip surfaces for the sows than wet-cleaning. Within half an hour of observation, up to 8.2 of 120 sows were occupied with the robot scraper, but without harming it. The use of robot scrapers in pig housings is recommended, although slight technical modifications should be made to the robot scraper.

Abstract Background The importance of high quality preprocedural bowel preparation is widely acknowledged, but suboptimal bowel cleansing still occurs in up to 20 % of all colonoscopy patients. The aim of this study was to evaluate the performance of a novel intraprocedural cleaning device for cleaning poorly prepared colons. Methods This multicenter feasibility study included patients aged 18 – 75 years who were referred for colonoscopy. Intraprocedural cleaning was performed in patients after a limited preprocedural bowel preparation regimen (2 days of dietary restrictions and 2 × 10 mg bisacodyl). The primary outcome was the proportion of adequately prepared patients (Boston Bowel Preparation scale [BBPS] ≥ 2 in each segment) before and after segmental washing with the new device. Secondary outcomes included: cecal intubation rate, procedure time, system usability, patient satisfaction, and safety. Results 47 patients (42.6 % male), with a median age of 61 years (interquartile range [IQR] 46 – 67 years), were included at three clinical sites. Cecal intubation was achieved in 46/47 patients (97.9 %). The cleaning device significantly improved the proportion of patients with adequate bowel cleansing (from 19.1 % to 97.9 %; P < 0.001) and median BBPS score (from 3.0 [IQR 0.0 – 5.0] to 9.0 [IQR 8.0 – 9.0]). Median cecal intubation time and total procedure time were 16.5 minutes (IQR 9.0−28.3) and 34.0 minutes (IQR 25.0 – 42.8), respectively. Physicians were satisfied with the ease of use of the device and it was well tolerated by patients. No severe adverse events occurred during the study period. Conclusions This feasibility study suggests that the intraprocedural cleaning device appears to be safe and effective in cleaning poorly prepared colons to an adequate level, allowing a thorough colorectal examination.

Arteriovenous fistula failure represents a major cause of hospitalization and a significant economic burden for end-stage renal disease patients on hemodialysis. The Optiflow (Bioconnect Systems Inc., Ambler, PA) is a new device developed to improve arteriovenous fistula outcomes and decrease failure rates by reducing the risk of stenosis and improving maturation rates. This case report describes a 50-year-old male with hypertensive nephropathy on dialysis who had multiple arteriovenous fistula failures in the past. He was scheduled to undergo brachiocephalic fistula construction using the Optiflow device. After 8 months of use, the new fistula developed a peri-anastomotic venous stenosis, just distal to the Optiflow device. To our knowledge, this is the first time such a complication has been reported.

New Distribution

Specimens and nests of Pomatoschistus pictus adriaticus have been caught for the first time along the French Mediterranean shore (Gulf of Lions). Six types of nests are found on sandy-gravelly bottom at 10 m depth and 25.3 to 27.5 g 1−1 salinity, using in 84.7% of cases, a valve of Cardium edule (3.3≤weight g≤40.6; 507≤surface mm2≤2490). Nest size, egg patch, surface area and nesting fecundity are positively correlated. Nesting fecundity varies between 669 and 4690 eggs. For a similar egg diameter, the egg height is less than that of P. minutus which spawns on the same bottom and localities. Larval length at hatching varies from 1.70 to 2.67 mm.

The possible relationship between Initial changes In functional characteristics of the peritoneal membrane In time and hemoglobin (Hb) or hematocrit (Ht) was analyzed as part of a prospective longitudinal study. The patients were Investigated twice: the first time within 3 months after the start of continuous ambulatory peritoneal dialysis (CAPD), and again 4 months later. Mass transfer area coefficients (MTC) for low molecular weight solutes and net fluid removal were calculated during a 4-hour dwell, glucose 1.36%. Thirty-four patients were analyzed. MTC (mean±SD, mL/min/1.73 m2) were higher during the first examination: urea 22.6 versus 19.9, p<0.05; lactate 15.6 versus 13.8, p<0.001; creatinine 10.5 versus 9.3, p<0.05; glucose 9.4 versus 7.9, p<0.001. Net fluid removal was lower during the first examination: 28 versus 99 mL/mln/1.73 m2, p<0.05. Hb and Ht increased between the two examinations (Hb: 5.4 vs 6.1 mmol/L, p<0.001; Ht: 0.26 vs 0.29, p<0.001). No relation was found between the absolute or relative change In Hb or Ht and the absolute or relative change In solute and fluid transport between the same examinations. In conclusion, Hb and Ht Increased between the first and second examinations. The simultaneously observed changes in peritoneal transport kinetics could not be attributed to changes In Hb or Ht. Therefore, the changes In transport kinetics during the first months on CAPD are probably due to the recent start of the treatment, possibly by an Increase In peritoneal surface area. LocalIrritation by the dialysate may be the causative mechanism.

Mesoporous tantalum oxide, Fe3+-doped mesoporous tantalum oxide, and bis(toluene) titanium reduced mesoporous tantalum oxide were used for the first time as Schrauzer-type photocatalysts for the conversion of dinitrogen to ammonia. The materials were characterized by XRD, TEM, XPS, and nitrogen absorption before and after catalytic runs. The results showed low to moderate activities depending on the composition. In contrast to previously studied Ti catalysts, Fe doping and heat pretreatment were not prerequisites for photocatalytic activity, but did improve the turnover rates by up to a factor of two. The optimal Fe loading for the tantalum oxides was found to be 1 wt% and the optimal heating condition at 300 °C for 3 h. Increased surface area and heat treatment were also found to improve activities. Contrary to our expectations, reduction of the mesostructure with bis(toluene) titanium had little effect on the catalytic activity. In spite of the dramatically higher surface areas of the mesoporous tantalum oxides as compared with bulk titanias used previously in this process, the overall catalytic activities were still less than those obtained in the Schrauzer system. This suggests that the increase in diffusion and surface area offered by the mesoporous structure is offset by the smaller crystalline domain sizes in the walls of the structure, leading to poor electron-hole separation and a reduction in catalytic efficiency. Key words: mesoporous, Schrauzer, ammonia, photocatalysis, tantalum oxide.

Aniline is a toxic organic pollutant that is abundantly present in the environment. One of approaches to remove the aniline is by adsorption process. In this study, mesoporous carbon nitride (MCN) was proposed for the first time to be a potential adsorbent for aniline. The adsorption studies were carried out at room temperature on the aniline solution with various initial concentrations for both bulk carbon nitride (BCN) and MCN. Owing to its larger surface area, the MCN showed much higher adsorption capacity towards aniline compared to the BCN. This result indicated that adsorbent with large surface area is very crucial in the adsorption of aniline. Comparison study was also carried out using mesoporous silica, MCM-41, which was reported to act as a good adsorbent for aniline. The adsorption capability of MCN was found to be higher than that of MCM-41. It was suggested that the MCN with larger pore diameter might have more suitable and favourable adsorption sites for aniline compared to MCM-41. This study obviously showed that MCN would be a new potential adsorbent for removal of aniline.
