Broadband perfect absorbers have been intensively researched for decades because of their near-perfect absorption optical property that can be applied to diverse applications. Unfortunately, achieving large-scale and heat-tolerant absorbers has been remained challenging work because of costly and time-consuming lithography methods and thermolability of materials, respectively. Here, we demonstrate a thermally robust titanium nitride broadband absorber with >95% absorption efficiency in the visible and near-infrared region (400–900 nm). A relatively large-scale (2.5 cm × 2.5 cm) absorber device is fabricated by using a fabrication technique of multiple-patterning colloidal lithography. The optical properties of the absorber are still maintained even after heating at the temperatures >600 ∘C. Such a large-scale, heat-tolerant, and broadband near-perfect absorber will provide further useful applications in solar thermophotovoltaics, stealth, and absorption controlling in high-temperature conditions.

藏族和古希腊关于人类起源神话都反映了“神造人”的世界性母题,体现了早期先民们对自身起源之谜的大胆探索,充满了神奇瑰丽的想象和创造精神;另外,二者都揭示了劳动与人类产生之间的密切关系,透露出强烈的人本主义色彩。作为不同文化的产物,藏族人类起源神话带有最素朴的唯物色彩,但已有后期佛教思想明显改造的痕迹,其“善”与“恶”对立统一的二元论思想构成了藏族文化哲学思维的基础;古希腊人类起源神话带有强烈的抗争精神,其精髓是西方“渎神”精神、悲剧精神的具体体现和升华。

Aneurysmal bone cyst (ABC) is a rare bone tumor accounting for 1% - 4% of benign bone tumors. Its etiopathogenesis remains unknown. The main site is the metaphysis of the long bones. ABC occurs almost exclusively in young people, with a slight female predominance. We report an exceptional case of ABC of the femur with involvement of the right hip in a 16-year-old girl in the Medical Imaging Department of Pr Bocar Sidy Sall Hospital of Kati (Mali). We will discuss the clinical and radiological aspects of this pathology. Observation: Mrs N C., aged 16, was referred to the orthopaedic-traumatology department for an X-ray of the right thigh, indicated as having a large, disabling thigh. Clinical examination revealed a large thigh measuring 890 mm in circumference, compared with 300 mm on the contralateral side. Radiographically, the femur showed a blown appearance, with the cortex thinned and broken in places. Exceptionally, the lesion affected the entire femur. On CT scan, we found a voluminous fluid collection occupying the entire right femur, including the right femoral head and homolateral ischium. The cortex was interrupted in places, and the adjacent soft tissues were thinned or laminated, but not infiltrated. Histology revealed haemorrhagic and inflammatory elements compatible with the diagnosis of ABC. Conclusion: ABC is a tumor entity that is often difficult to diagnose. Medical imaging, topographical distribution and histology form an indissociable whole to establish a diagnosis of certainty.

The mobile communication is nowadays one of the basic needs of humanity. It is essential to the flourishing of human beings. Considering this reality, the need to use its mobile phone is become more important and diversified. The subscribers of the various mobile telephone operators are increasingly demanding. This situation poses the problems of the cover mobile network to the operators and leads them to opt for several solutions and investments. The mobile operators in order to satisfy their customers use a policy of pushing the limits of network coverage in time and space for festive moments in targeted zones. Thus, we have conducted a study on the topic: study of a kit of GSM radio site for event-driven movable coverage. This work is applied to GSM (Global system mobile) network of the operator Orange-Ci, leader of mobile telephony in Ivory Coast. We thus proceeded under investigation initially of the various aspects of the ordinary sites (motionless radio site) which are already deployed with Orange-Ci in order to impregnate us infrastructures and equipment used. This study revealed us that a radio site comprises 4 parts: infrastructures, installations and energy equipments, installations and radio equipments, and installations and equipment of transmission. After the first analysis, we made a study of the movable site. The study of the movable site enabled us to see the various possible solutions to fulfill the basic functions of a movable radio site. After analysis we retained that our radio site will be built on a truck on which a mast of 25 m maximum length for the antennas will be embarked, it will be fed by a generator also embarked on the truck and the solution of transmission selected is the transmission by satellite more precisely technology VSAT. We choose the various equipments (radio, transmission, energy) according to features which we defined to constitute the kit of movable radio site.

The Hepatic sinusoidal obstruction syndrome (HSOS), also known as veno-occlusive disease (VOD), is a well-known complication of haematopoietic stem cell transplantation, of the treatment of Wilms tumor and rhabdomyosarcoma and maintenance therapy of acute lymphoblastic leukemias. Its occurrence is rare in other cancers of the child. We report the observation of a 7-year-old girl with Burkitt’s lymphoma who developed a severe HSOS during her second induction treatment with dexamethasone, cisplatin, cytosine arabinoside. The evolution was fatal. This observation shows that the diagnosis of HSOS should not be excluded in the absence of the risk factors usually described.

In African cities, today’s patterns of consumption are increasingly generating solid and liquid waste. This waste requires adequate management as it poses significant risks to public health and the environment. To meet the challenge in Ouagadougou, a waste treatment and recycling center has been implemented. The leachates from household refuse evacuated in this center are treated by two series settling ponds whose performances have been evaluated throughout the present study. For this purpose, samples were taken from the basins and analyzed weekly for two months. On these samples, the physical parameters (pH, temperature, conductivity), organic pollution indicators (BOD5, COD, SS), nitrogen pollution (nitrate, nitrite) and phosphorus pollution (ortho-phosphates) were evaluated according to AFNOR standards. The average of suspended-matter contents above 13,000 mg/L and this particulate pollution abatement recorded is 2.04%, whereas the Chemical Oxygen Demand reached respective maximum values of 660 and 480 mg/L for both basins. Nutrients such as nitrates were well eliminated whereas orthophosphates are released. PH values varied between 8.62 and 9.51, while electrical conductivity values varied between 482 and 625 μS/cm. The Fecal Coliforms reached maximum concentrations of 10,000 and 12,800 UFC/100mL.

The purpose of this paper is to understand the valorization of gold showings in the Seribaya deposit, western Mali. Samples taken from Air Core (AC) boreholes were subjected respectively to the magnetic susceptibility test and the X-ray fluorescence analysis. These results lead to the development of a simple methodology, based on signatures/indicators geochemical to identify lithology or to locate mineralization. We note that, compared to other chemical elements, Arsenic remains the most correlated with gold in the study area. Since this correlation remains weak (r = 0.16), it shows that Arsenic does not always accompany gold. There would be a generation of Arsenic related to mineralization, and other generations that would not be. The observation of the strip logs led to the identification of the lithologies (focusing on the immobile elements, Ti, V, Cr, Y, Zr) and the establishment of the alteration profile. Highly altered levels (Saprolite ± Saprock) are characterized by the disappearance of most mobile elements. A medium to strong correlation between gold mineralization and magnetic susceptibility measurements has been observed, in some places, and at depths. These mineralized intervals typically consist of quartz veins, suggesting that they have structural control over the mineralization. Gold mineralization is believed to be related to quartz veins. In addition, gold would be in paragenesis with a generation of Arsenic hosted in coarse sediments.

Fibromyalgia syndrome (FS) is a common chronic disease characterized by widespread musculoskeletal pain in certain anatomic locations. Even though Fibromyalgia’s prevalence and common symptoms in pregnant women are known, many issues related to the consequences of mother’s fibromyalgia on pregnancy outcome have not been enough explored. The aim of this study is to highlight the relationship between fibromyalgia of women who gave birth and pregnancy outcome parameters like child delivery ways and newborn health. A first preliminary epidemiology study was thus carried out in the Bingerville general hospital. Our results showed that fibromyalgia was prevalent in women who gave birth as among 271 women who gave birth, 48.03% have fibromyalgia. A high frequency of women with fibromyalgia delivered by caesarian section (79.7%). Apgar score indicated that newborns of the study have a good vitality as the score is higher than or equal to 7 for the majority of newborns. A large number of newborns were apparently in good health (160/184) compared to unhealthy newborns (24/184). We saw that a large frequency of unhealthy newborns were born from women with fibromyalgia (14/24;58.3%) while a low proportion of apparently in good health newborns were born from women with fibromyalgia. Healthy newborns have not been observed. All together, these data highlight the prevalence of fibromyalgia in women who gave birth and a relationship between fibromyalgia of mother, delivery modality and newborn health. However, in the situation of newborns’ health, the link was not direct.

Background: Cancer of the cervix is the most common cancer and the leading cause of death by cancer in women in developing countries. According to WHO, there were in 2002 in the world more than 500,000 new cases of cervical cancer, with more than 90% in developing countries. Secondary prevention of cervical cancer is done through screening of precancerous lesions and early diagnosis of cancer followed by treatment. Objectives: Our experience was reported in the management of a network of screening in the prevention of cancer of the uterine cervix. Method: After a program of training and upgrade to a pool of specialist doctor of obstetrics and gynaecology and midwifery centers health on visual screening methods, a reference site that is also a trainer site was defined and equipped with video-colposcopy and cryotherapy device. In April 2014, four peripheral sites have been installed with an equipment of lamp, magnifying glasses, acid acetic 5% and Lugol’s iodine. The screening network has been implemented and works on the model of reference-cross-reference. Results: The assessment of a year’s activity of the peripheral centers reported 993 patients, 653 consultations at the reference site, 106 precancerous lesions (6%), and 86 cases of references. The age of attendance peak lies in the age group of 35 - 55 years. Conclusion: The improvement of women’s participation requires organized screening, mass communication strategies, and systematic proposal of screening in consultation.
