The purpose of this study was to examine the impact of macro social factors （states, religion, region, Arab spring, terrorism, unrest （Shoe index）, democracy, corruption （GPI）, Human development （hdi）, low self-control, life stress events （LSE）, youth unemployment, religiosity, feeling （fear and anger）, youth unemployment and total unemployment） on Arab youth＇s radicalization. A sample of 6,730 Arab youth age 15-24 years was selected from Kuwait, UAE, KSA, Oman, Qatar, Bahrain, Jordan, Tunisia, Libya, morocco, Lebanon, Egypt, Gaza and Palestine and Syrian refuges in Jordan. A questionnaire of 43 items to measure radicalization was developed based on the literature review. A construct validity of the scale was estimated by calculating the correlation between radicalization scale and Low self-control scale and found a positive significant relationship （0.680, a = 0.000）, a sign of validity of the scale. A Reliability of the scale is strong and was estimated by Cronbach＇s alpha and was 0.947. An average of 46.6% of the participants was categorized as radicals with standard deviation of 12. macro social factors explained 64% of the variance on radicalization. It has a significant impact on radicalization （F = 807.6, a = 0.000）. Each single variable has a significant impact. The analysis revealed three groups of macro determinants of youth radicalization were identified：（1） Geographic factors： state, region, and Arab spring; （2） Social factors： religion, religiously, feelings, LSE and LSC; （3） Human security： unrest, terrorism, democracy, corruption, human development, youth unemployment and employment rate. To alleviate the consequences of radicalization, prevention policies should take in account youth concerns as partners and victims of radicalization. Policies need to focus on radicalization pull and push factors on micro-meso-macro level.

Heterostructured materials,defined as materials that contain multiple zones with dramatically different flow stresses,have the potential to push the envelope of the strength-ductility of metals and alloys beyond what can be obtained conventionally[1–3].A prominent example is the heterogeneous lamella Ti that is as strong as its ultrafine-grained Ti,while as ductile as the coarsegrained Ti[4].

Prediction of hypertensive disease in pregnancy remains challenging. Risk factor based screening utilizing history, physical characteristics, uterine artery Doppler and serum markers have been used with varying success. As hypertension in pregnancy appears to be associated with changes in the maternal vasculature, we have investigated the utility of maternal arterial elasticity measurement, prior to 20 weeks gestation, in the prediction of hypertensive disease in pregnancy. A hdi/Pulsewave CR2000 Research Cardiovascular Profiling System was used to obtain radial artery pulse pressure waveforms from 623 Caucasian women at the time of their first antenatal visit. Outcome data were available in 610 cases and these comprised the study group. The results showed that women who subsequently developed gestational hypertension (n = 20) had higher baseline systolic, diastolic and pulse pressure values (though within the normal range) but similar arterial elasticity to those patients who did not develop hypertension. Women who later developed pre-eclampsia (n = 23) had, in addition, reduced large artery elasticity and increased systemic vascular resistance compared with women who did not develop hypertension. The measurement of maternal radial artery elasticity in early pregnancy may provide an additional refinement in screening for hypertensive disease, particularly pre-eclampsia, in pregnancy.

Objective This study was undertaken to determine the effect of advanc ed ultras ound equipment on the ability to visualize fetal cardiac structures in obese gra vid women. Study design Singleton pregnancies undergoing initial ultrasound exam ination between 14 weeks and 23 weeks 6 days were included. Patients were classi fied by body mass index (BmI) (nonobese mI m2] and obese mI ≥30 kg/ m2]). The rate of suboptimal ultrasound visualization (SUV) of the fetal heart ( cardiac axis, cardiac position, 4-chamber, and outflow tracts views) was compar ed between patients examined by standard (hdi 3000) or advanced ultrasound equip ment (hdi 5000)-(ATL, Philips medical Systems, Bothell, Wash). Results Over a 5 -year period, 7029 singleton gestations met inclusion criteria; 2498 (35.5%) w ere clinically obese. There was no difference in gestational age, rate of low am niotic fluid volume, anterior placenta, or vertex fetal presentation between the groups. When the advanced ultrasound equipment was used, SUV of the fetal heart was lower in the nonobese population (20.8%vs 16.4%; Pmen (38.1%vs 35.5%; P=.27). However, obese patients who were e xamined by advanced ultrasound equipment after 18 weeks had less SUV of the outf low tracts (28.5%vs 23.1%, P=.04) but not of the 4-chamber view. Conclusion D espite advanced ultrasound equipment,maternal obesity significantly limits visua lization of the fetal heart. However, the advanced ultrasound equipment may some what benefit obese gravid women examined after 18 weeksgestation.
