in Chiapas highlands to southeast of mexico, the scarcity of water is worrying, according to technical reports of the iPCC the runoff will less between 150 to 250 mm per year in the southeast of mexico, this situation will increase the problems of water availability in Chiapas highlands in the future. For actually more of 18,160 small rural indigenous communities (SRiC) in Chiapas there is not drinking water. in order to contribute a given solution to scarcity of drinking water in the SRiC, The Autonomous University of Chiapas (UnACH in its Spanish acronym) and mexican institute of Water Technology (imTA in its Spanish acronym) designed and constructed in 1999 the Rain Water Harvesting (RWH) in Yalentay municipality of Zinacantan in Chiapas, mexico. The scientific and technical contributions of RWH are: The design guarantee the water quality for a prolonged time of storage avoiding the photosynthesis inside the system.not emitted greenhouse gasses because it doesn’t need any kind of fossil fuels;not produces anything kind of damage to the environment;it has to be inexpensive, using in its construction manpower and materials from de region;Store the maximum quantity of water in the minimum space. The RWH has increased the standard of living of the habitants from Yalentay and improving their health conditions.

女性生殖器割礼与尿结石

世界核心医学期刊文摘（妇产科学分册） 2006年第11期2卷 53-54页

作者： nour n.m. 朱亮 African Women's Health Center Brigham and Women's Hospital Department of Maternal Fetal Medicine 75 Francis Street Boston MA 02115 United States Dr.

BACKGROUnD: Female genital cutting is a cultural practice seen in parts of Africa and Asia. Women who have undergone type iii female genital cutting (excising the external genitalia and suturing the remnant tissue to cover the urethra and part of the introitus) can suffer various long-term complications. Defibulation, a procedure that opens the overlying scar can alleviate or resolve symptoms. CASE: A 32-year-old Somali woman presenting with type iii female genital cutting complained of infertility, dyspareunia, dysmenorrhea, and exquisite pain upon sitting. She underwent a defibulation procedure to create neolabia majora. intraoperatively, a 0.8 cm urinary calculus was found beneath the urethra. Postoperatively, all of her symptoms resolved. COnCLUSiOn: infibulated scars create a favorable environment for stagnant urine to crystallize and become a urinary calculus.

Purpose The purpose of this study was to examine the response of myokines to blood-flow restricted resistance-exercise(BFR-RE)in younger and older males before and after completing a 12-week resistance-training *** There were 8 younger(24.8±3.9 yrs)and 7 older(68.3±5.0 yrs)untrained male participants completed this *** and maximal strength(1Rm)measurem.nts were collected before and after a 12-week,supervised,progres-sive full-body resistance-training *** well,an acute bout of full-body BFR-RE was performed with venipuncture blood samples collected before and immediately following the BFR-RE,followed by sampling at 3,6,24 and 48 *** The 12-week training program stimulated a 32.2%increase in average strength and 30%increase in strength per kg of fat free *** response of particular myokines to the acute bout of BFR-RE was influenced training status(iL-4,untrained=78.1±133.2 pg/mL ***=59.8±121.6 pg/mL,P=0.019;iL-7,untrained=3.46±1.8 pg/mL ***=2.66±1.3 pg/mL,P=0.047)or both training and age(irisin,P=0.04;leukemia inhibitory factor,Pnges in strength per kg of fat free mass were correlated with area under the curve for iL-4(r=0.537;P=0.039),iL-6(r=0.525;P=0.044)and LiF(r=−0.548;P=0.035)in the untrained *** This study identified that both age and training status influence the myokine response to an acute bout of BFR-RE with the release of iL-4,iL-6 and LiF in the untrained state being associated with changes in strength per kg of fat free mass.

＜正＞in the frames of collaborate Russian-Chinese project of ionosphere response to magnetic storms research were continued the investigations along meridian in three directions: quiet ionosphere, weak and moderate storms, and great storms （geoactive periods on October-november 2003 and november 2004）. in this study the bulk attention is focused to the difference of ionospheric effects to weak and modern storms in different seasons. We present the results of morphological analysis and numerical modeling during the storms observed in different seasons. Here is received the following conclusion. in the winter at high latitudes the disturbances were positive at night and negative in day. in contrast at middle latitudes the disturbances are negative at night and positive in the day. in the summer the disturbances are mainly negative. At mid latitudes there are observed the small disturbances with amplitude less 10% both positive and negative. in the equinox the disturbance pattern is similar to the winter one, but with smaller amplitude. The numerical model for ionosphere-plasmasphere coupling that was developed at the iSTP SB RAS was used to interpret the observed variation of ionosphere structure. Calculation was carried out with correction of the corresponding empirical models according to the available data of different ground observations. A theoretical analysis of the processes controlling the mid-latitude ionospheric response to the geomagnetic storm showed a good agreem.nt of modeling results and measurem.nts, as well as made it possible to ascertain the crucial role of the neutral composition variations in the ionospheric parameter observed variations. At auroral and subauroral stations the electron density variability during the storm is much more pronounced. According to results of analysis of the ionospheric plasma convection trajectories, this variability is caused by the combined effect of convection and energetic electron precipitation. neutral thermospheri

喜山地区一些垂直地层走向的重力剖面表明,该区布格异常自南向北逐渐减减外,最北端的异常值为-500毫伽。不少学者研究了该陆-陆碰撞山链的布格异常与抬升、地壳厚度、俯冲作用,碰撞构造之间的关系,但重力异常的多解性妨碍了建立起正确模式。一般说来,建立模式时有两种做法,一种基于地壳均衡模式(Quresh,1986),另一种(Duray等,1987)是用岩石圈中地壳的负荷增加和挠曲来解释较大的负异常。根据岩石圈挠曲理论,考虑到喜山负荷和Hanga盆地的沉积物,我们对Chandigarh至Leh剖面做了布格异常的模式计算,证明山势负荷足以解释布格异常连续降低的趋势。在该剖面上,按Airy-Heiskanen模式估测的地壳厚度与负荷引起岩石圈弯曲得到的厚度相一致。但是。

腹主动脉瘤的发病率据估计介于千分之十到二十之间。其破裂率高、生存率低,因而引起人们对此病自然转归的重视。手术防止破裂的功效早已证实,但各家对手术适应证的看法不一;有人认为全部腹主动脉瘤患者均应手术切除,另则认为仅症状显著者宜行手术治疗。其争辨的部分原因可能与诊断方法学有关。六十年代时,除物理诊断和腹部X线照片外,尚无其它方法可用以判断未经手术的动脉
