Open Journal of Radiology 2017年第2期7卷 103-111页

作者： N’goran Kouame Fotso Sorel Manewa Amlan Marie-France Kouame Anne-Marie N’goan-Domoua Roger-Daniel N’gbesso Department of Radiology Yopougon University Hospital Abidjan Cote d’Ivoire

Objectives: The aim of this study was to determine the epidemiological-clinical profile of patients with scrotal infectious pathology in Abidjan and describe the ultrasound features of this scrotal infectious pathology. Methods: This was a prospective study of 80 cases of scrotal infectious pathology objectified by ultrasound at Yopougon University Hospital from 1 January 2015 to 31 December 2015. Ultrasounds were performed using a high-frequency linear probe in B and Color Doppler modes by senior radiologists. The epidemiological-clinical data were recorded from the ultrasound request form and the interrogation of the patient. Results: The average age was 23 years with extreme ranging from 16 to 40 years. Soldiers were the most concerned (40%) followed by students (30%). The painful large bursa was the quasi constant presenting feature (95% of cases) and fever was associated in less than half of the cases (45% of cases). The scrotal involvement was most often unilateral (85% of cases) and the left side was involved in 70% of the cases. Epididymitis was the most frequent pathology (60%) followed by orchiepididymitis (30%) and orchitis (10%). The most commonly encountered accompanying ultrasound findings were envelope thickening (100%), intravaginal fluid effusion (60%), and Doppler Hypervascularization (30%). Conclusion: In Abidjan Scrotal infectious pathology is most often encountered among young soldiers or students most often with a ± febrile large bursa. The most common pathology is left unilateral epididymitis.

The collaboration tools offered by Cloud Computing have increased the need to share data and services within companies or between autonomous organizations. This has led to the deployment of community cloud infrastructures. However, several challenges will arise from this grouping of heterogeneous organizations. One of the main challenges is the management of trust between the actors of the community. Trust issues arise from the uncertainty about the quality of the resources and entities involved. The quality of a resource can be examined from a security or functional perspective. Therefore, ensuring security and monitoring the quality of resources is to ensure a high level of trust. Therefore, we propose in this paper a technique for dynamic trust management and quality monitoring of resources shared between organizations. Our approach consists, on the one hand, in evaluating the quality of resources based on quality of service measurement attributes and, on the other hand, in updating the trust values according to the information deduced from these measurements. The proposed framework is evaluated in terms of resource sharing success rate and execution time. Experimental results and comparison with TNA-SL and InterTrust models show that the framework can identify and track the behavior of malicious organizations with relatively low execution time.

为了研究钢包冶金中不同搅拌方法对物理和化学反应的影响,已经进行了4～9 t 钢水的工厂中间试验。对在大气下和真空下进行的通过透气砖吹气净化和电磁搅拌,已作了研究。脱硫等渣钢反应需要渣铜界面混合得好,所以必须采用气体净化来实现。去除非金属夹杂等则应采用电磁搅拌。对于脱氧钢的真空处理,只要在电磁搅拌时加入少量惰性气体,就可以使反应速度大增。

Laparoscopic surgery seems to have a general physiological benefit compared to conventional procedures in several clincal studies especially regarding intestinal anastomotic healing. Reliable experimental data concerning the particular mode of beneficial action are lacking. Clinical studies will not be able to identify the variables responsible for this effect. To establish a feasible, standardized experimental model to investigate variables such as humidity and perioperative room temperature, we employed an incubator designed for neonatal care. This allows individual manipulation and observation of above mentioned variables. Our initial results show that creating intestinal anastomoses in the incubator is safe and easy to perform, creating a valuable possibility to influence perioperative conditions for experimental and clinical research.

We report mid-infrared Ge-on-Si waveguide-based PIN diode modulators operating at wavelengths of 3.8 and8 μm. Fabricated 1-mm-long electro-absorption devices exhibit a modulation depth of >35 dB with a 7 V forward bias at 3.8 μm, and a similar 1-mm-long Mach–Zehnder modulator has a Vπ· L of 0.47 V · cm. Driven by a 2.5 Vpp RF signal, 60 MHz on-off keying modulation was demonstrated. Electro-absorption modulation at 8 μm was demonstrated preliminarily, with the device performance limited by large contact separation and high contact resistance.

We demonstrate low-loss hydrogenated amorphous silicon(a-Si:H) waveguides by hot-wire chemical vapor deposition(HWCVD). The effect of hydrogenation in a-Si at different deposition temperatures has been investigated and analyzed by Raman spectroscopy. We obtained an optical quality a-Si:H waveguide deposited at 230°C that has a strong Raman peak shift at 480 cm^(-1), peak width(full width at half-maximum) of 68.9 cm^(-1), and bond angle deviation of 8.98°. Optical transmission measurement shows a low propagation loss of 0.8 dB/cm at the1550 nm wavelength, which is the first, to our knowledge, report for a HWCVD a-Si:H waveguide.
