随着数据流量的指数增长，蜂窝网络运营商面临着一个岌岌可危形势：满足快速增长的流量的同时降低成本并提高每用户平均收入(ARPU)。由于电费占据网络运营商支出的20%0%，这种形势只会随着移动网络消耗能量费用的增加变得更加严峻。在本论文中，我们提出了一种叫做细胞缩放的新技术来减少基站的能量消耗。通过细胞缩放技术,基站可以基于用户的位置动态地调整它们的覆盖半径和发射功率。根据用户的位置和信噪比的需求，发射功率可以设置成最小级别。基站从来都不完全关闭。我们首先分析用户在一天之中每个时间段的行为，因而我们可以建立基站密度和用户密度之间的关系。然后根据在一天之中每个时间段的用户数量的所有信息，我们决定发射功率以满足每个用户的需求和保证服务质量。我们也提出提高基站某些部分的能源利用率，如冷却部分，帮助我们节省高达25%的基站消耗的总能量。仿真显示，在不降低用户服务质量的前提下，本文提出的算法能够节省高达40%的网络能量消耗。

The pneumococcal septic arthritis is uncommon in healthy adults. In most cases, it occurs in patients with immune deficiency. Its exceptional location at the wrist can maintain doubt with rheumatic causes which are more frequent. IgG4 deficiency found in this patient was the only cause that could be impugned. We report the case of a young woman of 46 years without any evident cause of immunodeficiency and any particular risk factor, managed for septic arthritis of the wrist due to Streptococcus pneumoniae. This case without any apparent risk factors demonstrates that pneumococcal infection in a more distant articulation of the ENT is still possible. Scan has been a very significant contribution in confirming the positive diagnosis that leads to surgical drainage. The approach of the systematic search for the gateway must be done. In the study of the patient’s immune status, the realization of the protein profile could be interesting and then guide the practitioner in the decision to vaccinate the patient against Streptococcus pneumoniae if he was not. We recommend looking always for a cause of immunodeficiency including primary Ig defiencies even among adult.

Elbow dislocation associated with ipsilateral Galeazzi fracture is a rare pattern of injury. Only seven cases were reported in the literature. We reported another case in a 42 years old man. Closed reduction of the dislocated elbow joint was immediately performed under sedation. Because the patient did not want surgery for radius, it was decided to manage the fracture conservatively. The lack of clinical improvement motivated operative treatment for Galeazzi fracture 56 days after injury. We have discussed the treatment option and the result obtained. The prognosis of this associated injury is related to the DRUJ dislocation, which should not be misdiagnosed.

Environmental contamination of food is a worldwide public health problem. Folate mediated one- carbon metabolism plays an important role in epigenetic regulation of gene expression and mutagenesis. Many contaminants in food cause cancer through epigenetic mechanisms and/or DNA instability i.e. default methylation of uracil to thymine, subsequent to the decrease of 5-methylte- trahydrofolate (5 mTHF) pool in the one-carbon metabolism network. Evaluating consequences of an exposure to food contaminants based on systems biology approaches is a promising alternative field of investigation. This report presents a dynamic mathematical modeling for the study of the alteration in the one-carbon metabolism network by environmental factors. It provides a model for predicting “the impact of arbitrary contaminants that can induce the 5 mTHF deficiency. The model allows for a given experimental condition, the analysis of DNA methylation activity and dumping methylation in the de novo pathway of DNA synthesis.

Double fracture-dislocations of the thumb are rare. Only a single case report of a simultaneous extraarticular fracture of the base of the first metacarpal and dislocation of the metacarpophalangeal joint has been previously reported. We report the second case report of this injury in a 20-year-old man. The patient had an excellent outcome after treatment.

The solar chimney can generate airflow through the living space of the building to provide cooling. Hence, solar energy represents the best renewable, environmentally friendly source of energy that can be used for heating and cooling of houses. The present paper reports the numerical study of the performance of the mixed convection in the associated hybrid Photovoltaic/Thermal chimneys integrated into building for natural habitat ventilation. The front side glass plate of the chimneys is heated by a non-uniform daily solar radiation flux. Air is considered to be the cooling fluid. The stream fucntion-vorticity formulation with a finite difference numerical discretization solution scheme has been adopted. The system of algebraic governing equations is solved by Thomas algorithm method. The aim of the present paper is to study and to predict the dynamic fields and particularly of the mass flow rate of the air thermosiphon drawing in the associated hybrid Photovoltaic-Thermal chimneys integrated into a building for passive cooling in the habitats. The effects of the governing parameters, namely Reynolds number (30 ≤ Re ≤ 200), Rayleigh number (103 ≤ Ra≤ 105), the integrated chimney width on the fluid flow and the heat transfer characteristics, are studied in detail. The local Nusselt number, streamlines, isotherms, PV cells electrical efficiency and the outlet velocity at the top of the channels are the results represented versus the above controlling parameters.

The aim of this work is to inventory Edible Wild Fruit Species （EWFS） highly consumed by local people during food shortage periods in Togo. Ethnobotanical surveys were carried out in four ecological zones （I, II, III ＆ IV） involving a sample of 433 persons from 29 ethnic groups. Semi-structured interview, field observation, group discussions were used to collect data. Food shortage periods were defined using the agricultural calendar of main crops in three ecological zones （I, II, ＆ III）. One hundred and one EWFS belonging to 84 genera and 39 families were inventoried. The three main types of use of the EWFS were direct consumption, condiments and medicines. Twenty among the 101 EWFS recorded were highly consumed during food shortage periods with respectively 15 EWFS in ecological I, 14 in zone 1I and 12 in ecological zone III. All edible fruits consumed during food shortage periods were fresh fruits with abundant pulp. Six fruit species were sold to bring income to local households. These species were those which benefit from conservation measures through their husbandry in agroforestry systems.

Introduction: Despite extensive experience with civilian gunshot fractures or wounds, no consensus exists on a standard protocol to manage these injuries. Many authors recommended immediate debridement, but the optimal timing of internal fixation and the use of antibiotic have not been determined. The purpose of this paper is to present and discuss our experience. Material and methods: In January 2007, a treatment protocol was put in place for the evaluation and management of fractured extremities resulting from civilian gunshot wounds. Sixty-three patients with 64 fractures had been managed by this protocol for gunshot fractures between January 2005 and January 2012. There were 56 male and seven female. Their mean age was 33.1 years (range: 17 - 61 years). Thirteen patients (20.6%) were able to provide a description of the weapon. Only 15 patients had entry and exit wounds. The mean follow-up period was 27 (range, 20 - 58) months. The main factors assessed were the surgical site infection, the fracture union and the functional status. Results: Out of the 63 patients, 14 patients developed a wound infection (five superficial and seven deep infections). Wound infection was significantly associated with associated injuries (p = 0.0388), fractures sites requiring fixation (p = 0.024), the fracture pattern (p = 0.0412), operative modalities (p = 0.0400). There were nine cases (14.1%) of fracture non-union. The mean time to union was 15 weeks (range: 5 - 32 weeks). Five patients developed chronics osteomyelitis. The average SMFA score for all of the patients was 23.8 (range: 0 - 56.3). The mean dysfunctional and bother indexes were 18.3 (range: 0 - 52.7) and 22.6 (range: 0 - 66.1), respectively. The SMFA total score and dysfunction index had a significant correlation based on presence or absence of associated injuries (p < 0.0001). But bother index did not show the same correlation (p = 0.452). The average length of hospital stay was 11.3 days (range: 3 - 64). Conclusion
