AIm. To assess the practice of Egyptian physicians in screening patients for hepatocellular carcinom.(HCC). m.THODS: The study included 154 physicians from.all over Egypt caring for patients at risk for HCC. The study was based on a questionnaire with 20 item.. Each questionnaire consisted of two parts:(1) personal inform.tion regarding the physician(nam., age, specialty and type of health care setting); and(2) professional experience in the care of patients at risk for HCC developm.nt(screening, knowledge about the cause and natural course of liver diseases and HCC risk). RESULTS: Sixty-eight percent of doctors with an m. degree, 48% of doctors with a m.ster degree or a diplom. and 40% of doctors with a Bachelor of m.dicine, Bachelor of Surgery certificate considered the hepatitis C virus(HCV) genotype as risk factor for HCC developm.nt(P m.dicine, internal m.dicine or gastroenterology and 67% of physicians in other specialties advise patients to undergo screening for HCV and hepatitis B virus infection as well as liver cirrhosis(P m.nistry of Health(m.H) doctors consider HCV infection as the leading cause of HCC in Egypt(P m. degree, 55% of doctors with a m.ster degree or a diplom., 56% of doctors with an m.BCH certificate, 74% of doctors in University Hospitals and 46% of m.H hospital doctors consider abdom.nal ultrasonography as the m.st im.ortant investigation in HCC screening(P m.dicine, internal m.dicine or gastroenterology and 37% of physicians in other specialties recom.end as HCC screening interval of 3 m.(P m. degree, 50% of doctors with a m.ster degree or diplom. and 60% of doctors with an m.BCH certificate follow the sam. ***: In Egypt, physicians spe

To paraphrase the Greek philosopher Heraclitus, change is the only constant in construction projects. Changes in scope occur as projects progress from.design through practical com.letion. FIDIC General Conditions Clause 13 [1] is one of the m.st im.ortant term. and im.lem.nting. It is also m.jor factor for project success. Once all project parties understand and fairly use this clause, the im.act will be m.nim.sing the expected disputes by 50% at least. Thus, this paper is considering illustrated variation order clause by flow chart technique to ensure that all the engineers are handling easily those subclasses.

The objective of the present work is to test the effectiveness of probiotic potency of regular yoghurt, synbiotic yoghurt and traditional ferm.nted Egyptian sobya containing endogenous probiotic strains com.ared to unferm.nted rice m.lk porridge. m.thods: The study consisted of 28 m.le subjects with m.an age of 13.9 ± 0.1 years. The subjects were divided into four groups, three groups consum.d one of three ferm.nted supplem.nts, while the fourth group served as a control group. Stool and urinary sam.les were carried out prefeeding and after 3-week nutritional intervention for assessing five indicators of revelance to colonic m.tabolic activities. The ferm.nted supplem.nts used for evaluation were regular yoghurt, synbiotic yoghurt and traditional ferm.nted sobya;while the fourth group was given unferm.nted rice m.lk and served as control. Intestinal perm.ability was assessed by the urinary lactulose m.nnitol ratio. Results: The m.an fecal total lactobacilli counts increased (P m.tion of the three ferm.nted supplem.nts (P m.ared to the pre-intervention levels. Sim.lar trends were observed for genus bifidobacterium. On the contrary, enterobacteraceae counts were reduced in all the three groups consum.ng ferm.nted supplem.nts.

A hybrid RANS-LES approach is used to resolve the Fore-body Side Vortex (FSV) separating from.the KVLCC2 hull at 30° drift angle and Reynolds num.er ReLoa ≈ 2.56e6. The perform.nce of the DES approach is evaluated using a proper grid study. Besides, the following aspects of the CFD results are investigated: the resolution of turbulent energy, the prediction of instantaneous and tim.-averaged vortical structures, local flow features, the lim.ting stream.ines and the evolution of the vortex core flow. New PIV data from.wind tunnel experim.nts is com.ared to the latter. The results form.a basis for future investigations in particular on the vortex interaction further downstream.and the applicability of different kinds of turbulence m.dels to trailing vortices like the FSV. Turbulence m.delling is realised with the k-ω-SST-IDDES m.del presented in [1], the grids’ cell count is 6.4 m. 10.5 m.and 17.5 m. Grid convergence of the tim.-averaged vortex core flow is observed. OpenFOAm.version 1806 is used to carry out the sim.lations and snappyHexm.sh to build the m.sh.

Standard laboratory procedures and rem.te sensing techniques were em.loyed in the characterization of gold bearing rocks of the Paishanlou area. Results indicate that, the rocks were form.d in an alteration com.lex of m.dium.tem.erature and pressure. The area was under intense polym.tam.rphism.(ductile shearing, and hydrotherm.l m.tam.rphism., which occurred along the deform.tion zone stretching from.Jinzhou to Fuxin. The area bears som. propylitic, phyllic (or sericitic) and argillic alteration styles. Gold m.nerals are contained in fine grained pyrite in silicified zones, and associated with m.tam.rphosed Precam.rian rocks. The host rock is com.osed of gneiss, m.lonite and trondhjem.te granite, and has a distinctive gold lead geochem.cal affinity.

Chronic non-specific low back pain has an im.ortant psychological im.act. Objectives: To determ.ne the prevalence of anxiety and depressive disorders (ADD) and factors associated to their apparition in patients suffering from.chronic non-specific low back pain in rheum.tological consultation in Lom.. Patients and m.thods: It was a cross-sectional study, conducted from.October 1st, 2015 to 31st m.rch 2016. This study focused on all patients suffering from.com.on chronic low back pain without psychiatric history in the Rheum.tology Ward at the Sylvanus Olym.io’s Teaching Hospital of Lom. and who have given their consent. The psychological evaluation was carried out through Ham.lton scale. The processing, the statistical treatm.nt and analysis of our data have been carried out using Epiinfo software, version 7.1.5. The investigation was approved by the local Ethics Com.ittee. Results: 48 (39 wom.n and 09 m.n) out of 123 patients with chronic lower back pain presented anxiety and depressive disorders (ADD) accounting for a prevalence rate of 39%. Their average age was 50.3 years old. The m.st frequent ADD was: psychic anxiety (58.6%), depressive m.od (51.3%), difficulties to feel asleep (47.9%) and disturbed or agitated sleep (43.1%). Factors associated with the anxiety and depressive disorders in com.on chronic low back pain were: fem.le gender (p = 0.02), dependent children (p = 0.02), occupation (reseller (p = 0.002), liberal profession (p = 0.009), m.nthly financial incom. (p = 0.002), surroundings fam.ly (0.009), m.dical history (p = 0.0002) and pain’s intensity > 7 (p = 0.04). Conclusion: This study shows the high frequency of anxiety and depressive disorders in com.on chronic low back pain and their influence by socio-econom.c and dem.graphic factors.

对浙江省内花岗质岩石样品薄片在偏光显微镜下鉴定,试图建立矿物学与微构造之间的联系,确定裂隙分布矿物学控制因素,并调查微裂隙与交代变质蚀变之间的关系.薄片显示花岗质岩石主要由斜长石、钾长石、石英和云母组成.其中长石和云母解理发育,在结构上更易于变形,而石英则表现为均质特征,其中的裂隙比其他矿物(长石、云母)中更发育.这些解理和裂隙接纳流体进入并造成交代变质.在此过程中,黑云母被白云母交代而形成石英并释放出钾,这些钾进而交代斜长石而形成钾长石.值得关注的是,一些矿物颗粒边界显现出很少的变形,如钾长石-斜长石边界和石英-石英边界呈现较低程度的颗粒间碎裂,并变得可能比以前更坚硬,这是因为重结晶作用和交代作用胶结了以前的碎裂结构.最后,变形作用影响到整个岩石,为流体通过岩石打开通道,进一步的微裂隙对大规模钾交代变质作用的发生至关重要.研究区内花岗岩的矿物学及裂隙特征表明,交代作用可以作为可靠的构造标志,用以恢复浙江花岗岩现代和古裂隙的几何特征.
