The use of ionic liquids (ILs) is a relatively new and promising technology for CO2 capture and storage (CCS). Ionic liquids, which are essentially organic salts with melting points below 100 °C, are particularly attractive owing to their negligible volatility, chemical and thermal stability, and most importantly, their designability. Their low reaction enthalpy with CO2 allows regeneration under less energy intensive conditions relative to conventional amine solvents, and choosing their anion/cation pairing can allow their properties to be controlled. Although conventional ILs are able to physically absorb CO2, greater capture capacities can be achieved by tethering functional groups which can chemically bind to CO2 on either or both of the cation and anion. In addition to liquid–gas capture, ILs have also demonstrated success when incorporated into gas separation membranes. To date, most studies have been focused at the laboratory scale and under ideal conditions (i.e., capture under high CO2 partial pressures, and regeneration in N2); however, in order to progress with this technology, it is imperative to explore the behaviour of ILs under industrially-relevant environments. In addition, further process simulation and economic studies should be carried out to help scale up the technology.

The effects of Al vacancy, Li vacancy, Al anti-site and Li anti-site point defects on the elastic and thermal properties of L12–Al3Li intermetallic compound were investigated by the first-principle pseudopotential plane-wave calculations. The results show that Li anti-site and Al anti-site can easily form in L12–Al3Li. Li vacancy slightly increases hardness and the Debye temperature, whereas Li anti-site, Al anti-site, and Al vacancy impose the opposite influence. All these point defects have no obvious impact on the brittleness of L12–Al3Li. Under the Debye temperature, the specific heat of L12–Al3Li weakly decreases with the content of Li vacancy, but increases with those of Li anti-site, Li anti-site, Al anti-site, and Al vacancy.

Traditional method of insulator defect identification is manually operated, which has low efficiency and high cost. Therefore, an automatic method of insulator defect identification is proposed in this paper. Firstly, image segmentation was operated by classification method of Random Forest (RF) to realize the object recognition of the insulator. Then, the method of Convolutional Neural Network (CNN) was adopted to classify the normal and defect states of insulators, and finally, the location of self-explosion defect identification was realized by Faster Region-Convolutional Neural Network (Faster R-CNN). A large number of images of insulators taken by Unmanned Aerial Vehicle (UAV) were used as experimental data to verify the method. The results show that the method in this paper could efficiently identify the defects of insulators, and the recognition rate reached 89.0%. The results can provide some references for the research of insulator defect identification of transmission lines.

The influence of electric field on the photodetachment of H− in magnetic field near a metal surface has been studied using the closed-orbit theory. It is found that the photodetachment of H− in the magnetic field near a metal surface is not only related to the electric field strength but also to the electric field direction. If the electric field F is along the +z axis and no matter what value of the F is, it all can strengthen the oscillation in the photodetachment cross section. However, if the electric field is along the −z axis, the situation becomes much more complicated. When the electric field is small, the cross section approaches to the case of H− in magnetic field near a metal surface. If the electric field strength continues to increase and just be able to counteract the metallic attraction, then no closed orbit can be formed. So the cross section is nearly the same as the case of H− without any fields. If the electric field further increases, the cross section approaches to the case of H− in downward electric field near a metal surface.

Objectives: The aim of Working Group 3 was to focus on three topics that were assessed using patient-reported outcome measures (PROMs). These topics included the following: (a) the aesthetics of tooth and implant-supported fixed dental prostheses focusing on partially edentulous patients, (b) a comparison of fixed and removable implant-retained prostheses for edentulous populations, and (c) immediate versus early/conventional loading of immediately placed implants in partially edentate patients. PROMs include ratings of satisfaction and oral health-related quality of life (QHRQoL), as well as other indicators, that is, pain, general health-related quality of life (e.g., SF-36). Materials and methods: The Consensus Conference Group 3 participants discussed the findings of the three systematic review manuscripts. Following comprehensive discussions, participants developed consensus statements and recommendations that were then discussed in larger plenary sessions. Following this, any necessary modifications were made and approved. Results: Patients were very satisfied with the aesthetics of implant-supported fixed dental prostheses and the surrounding mucosa. Implant neck design, restorative material, or use of a provisional restoration did not influence patients’ ratings. Edentulous patients highly rate both removable and fixed implant-supported prostheses. However, they rate their ability to maintain their oral hygiene significantly higher with the removable prosthesis. Both immediate provisionalization and conventional loading receive positive patient-reported outcomes. Conclusions: Patient-reported outcome measures should be gathered in every clinical study in which the outcomes of oral rehabilitation with dental implants are investigated. PROMs, such as patients’ satisfaction and QHRQoL, should supplement other clinical parameters in our clinical definition of success. © 2018 The Authors.

We predict that doped Mn atoms can not efficiently improve magnetism of yttrium clusters in most cases, which is different from Mn–Ge, Mn–Bi and Mn–B complexes. The calculated results show that the ground state structures of MnY N clusters favor growth patterns of octahedron structures, with Mn atom occupying the center of yttrium framework at N ≥ 6. There are three minima of the HOMO–LUMO gap with N = 6, 10 and 13 which can be mainly attributed to obvious elevation of energy level of the HOMO. The computed magnetic moment per atom displays size-dependent behavior with oscillational odd–even character. The Mulliken population analysis shows that the doped Mn atom, with antiferromagnetic alignment at N = 5, 9, 11 and 13, tends to reduce the magnetic moment of the system of N ≥ 6. Both structure and chemical bonding are responsible for the variation of magnetism of Mn doped yttrium clusters.

In this study, we aimed to explore the curative effect and safety of neural stem cell intrathecal transplantation for the treatment of cerebral hemorrhage. We transplanted 4.0 x 10(8) neural stem cells per procedure into the subarachnoid space by lumbar puncture 7 days after cerebral hemorrhage, twice a week, a total of 4 times. NIHSS scores and brain CT scans were conducted to assess neural functions and the volume of perihematoma lesions in patients on days 1, 7, 14, 21, and 28. We found that the NIHSS scores and the volume of the perihematoma lesions were significantly reduced after day 14. The differences before and after treatment were highly significant in intra- and between-group comparisons (P < 0.05). There were no adverse reactions, except for transient fever and shivering in a few patients. Our data suggest that the use of neural stem cells in intrathecal transplantation for the treatment of cerebral hemorrhage is safe and effective.

Specimens of 100 unrelated individuals were collected from Han ethnic group in Sichuan Province of China. DNA was extracted from blood specimens using Chelex 100 method (1).

A case of a false aneurysm arising at the proximal suture of an aortic root replacement with a pulmonary autograft is presented. This complication did not occur in the first postoperative month but was discovered late, and the female eight-year-old patient was in an extremely serious condition. She was reoperated on an emergency basis but died of acute pulmonary artery hypertension. The mechanism of the occurrence of such a case is discussed. In the absence of infection, structural weakness of the right ventricular muscle with progressive tearing is suggested. Strict and prolonged echocardiographic surveillance after the Ross procedure and early reoperation are mandatory.

At the Central Hospital of Yaoundé, Cameroon, 10 ano-rectal injuries were treated over a period of 5 years. There were the same number of men and women and all patients were young (range: 7 to 35 years). The cause was illegal abortion in 2 cases and impalement following a fall from a tree in 3. The time lapse between injury and treatment was longer than 24 hours in 5 patients. In 2 cases the lesions were minor and simple debridement was possible. In the remaining 8 cases, construction of a colostomy was required using either the Hartmann terminal-type technique (n = 5) or the exclusion technique (n = 3). Three patients died: one from traumatic shock and two from septic shock. Complications were observed in 4 patients: 2 infections and 2 mechanical complications. Two patients presented permanent sequels including one with partial fecal incontinence. This study confirms the difficulty in management of ano-rectal injuries with limited facilities and reveals the variety of situations that can lead to these injuries especially in children in Africa.

Over a period of 3 years, 49 typhoid perforations of the small intestine were treated at Yaoundé Central Hospital. These 34 men and 15 women with a mean age of 29.6 years presented sthenic peritonitis in 20 cases and more difficult to diagnose asthenic peritonitis in 29 cases. The perforation was always located at the end of the ileum and was single in 40 cases, double in 6 cases and triple in 3 cases. Surgical management in association with intensive care and multiple agent antimicrobial therapy consisted in sleeve resection in 29 cases, resections with an exteriorized anastomosis in 15 cases, and ileocolonic intubation in 5 cases. The postoperative complications were suppuration of the wall (n = 4), intestinal fistula (n = 3), evisceration, and residual abscess. There were 9 deaths (18.4%) including 4 after sleeve resection and 5 after resection with an exteriorized anastomosis. On the basis of this experience, the authors describe the diagnostic difficulties posed by typhoid perforations, discuss surgical techniques proposed in the literature, and emphasize the value of sleeve resection.

The authors report 3 new cases of Male Internal Pseudohermaphrodism. It is a scarce entity. The discovery is fortuous during the cure of hernia or cryptorchidism. The family history has nothing particular. The main problem of this syndrome is its treatment. Our attitude consisted in conserving the mullerian derivatives and treating the hernia or the cryptorchidism. Hysterectomy is not justified for the following reasons; no case of cancerisation of the mullerian derivatives has not yet been reported. The vasa deferens and uterus are in intimate relationship; the dissection is therefore dangerous. We did not perform systematic castration in order to protect fertility. The removal of the testis is performed only when the gland is intraabdominal and undescendable considering the major risk of cancerisation.

This work was carried out consequently to three observations followed up by regrettable consequences: one right hemicolectomy about acute perforated typhlitis, two post-operative fistulae about clinical feature of pseudo-appendicitis. A study was undertaken on 183 patients; 160 patients complained of chronic in right iliac fossa, 23 of acute or subacute pain. Out of the 160 chronic patients, treated by metronidazole did not show symptoms anymore. Out of the 23 acute patients, 14 were cured thanks to the amebicide test-treatment and the 9 others showed during surgical intervention: 4 phlegmonous appendicitis, 3 appendicitis with inflammation of the mucous membrane, 2 appendicitis with abscess. In the acute cases, the duration of the therapeutic test was 10 ho. In the operated chronic cases (37 out of 160), histology substantiated surgery in revealing typical lesions of chronic appendicitis sometimes associated to anatomical deformity such as diverticulum. The authors strongly suggest such a test-treatment by metronidazole. It is well accepted and has enabled to get rid of post-operative morbidity of appendicectomy in tropical milieu.
