New Zealand biodiversity has often been viewed as Gondwanan in origin and age, but it is increasingly apparent from molecular studies that diversification, and in many cases origination of lineages, postdate the break-up of Gondwanaland. Relatively few studies of New Zealand animal species radiations have as yet been reported, and here we consider the species-rich genus of carabid beetles, Meco...

Using Magellan SAR images and the Schaber et al. [1998] crater data base we examined impact craters in the area north of 35øN and determined the geologic units on which they are superposed. The crater density of the regional plains with wrinkle ridges (Pwr) was found to be very close to the global average and thus the mean surface age of the plains is close to the mean surface age of the planet...

The Main Central Thrust shear zone is the dominant crustal thickening feature in the Himalayas, largely responsible for the extreme relief and mass wasting of the range. Along the Bhagirathi River in NW India, the Main Central Thrust is several kilometers thick and separates high-grade gneisses of the Greater Himalayan Crystallines from Lesser Himalayan metasedimentary rocks. Th-Pb ion micropro...

Abstract New lithologic and detrital zircon (DZ) U-Pb data from Devonian–Triassic strata on St. Lawrence Island in the Bering Sea western Brooks Range of Alaska suggest affinities between these two areas. The constitutes part Arctic Alaska–Chukotka microplate, but tectonic paleogeographic are unknown or at best speculative. Strata form a carbonate succession Mississippian(?)–Triassic clastic th...

caesarean section is considered as a major surgery which is accompanied by several complications. the present study aimed to determine the effect of behavioral intention model-based educational intervention on reducing the caesarean section among pregnant women. the present interventional study was conducted on 100 primiparous women in the third trimester of pregnancy who were covered by the he...

abstract background: data was reported in iran in 2013 has shown that almost 42 percent of deliveries in public hospitals and 90 percent in private hospitals were carried out with cesarean section. this high rate of cesarean requires careful consideration. it seems that making decision for cesarean is done under the influence of cultural perceptions and beliefs. so, this study was conducted to ...

background: since preterm delivery is an important problem in obstetrics, it is necessary to know the risk factors. periodontal disease is an infectious disease and infection is risk factor for preterm delivery. respecting to the mechanisms of preterm delivery and because involved mediators in this procedure are synthesized in periodontal disease, gum disease is investigated as risk factor for ...

introduction: sonophoresis has been assessed as a novel approach to create skin permeability and drug delivery using low frequencies of ultrasound waves in the range of 20 khz to 3 mhz. in this study, a system including seven 40 khz piezoelectric transducers and an insulin chamber designed by the medical physics research center has been evaluated on hyperglycemic rabbits. materials and methods:...

abstract the main objective of this paper is to apply the canalman model in the performance assessing of different water operational scenarios in the west main canal of dez irrigation network. the proposed model was calibrated and validated based on the real data of march and april 2006. the real water operational condition during five months (may to september 2006) was simulated. for this peri...

recently, specific attention has been paid to aptamers, short dna or rna, as a tool for cancer diagnosis and therapy. in the present study mcs nanogels were prepared by myristate: chitosan at 1:9 ratio and were characterized by several techniques. a selected ssdna aptamer(apt) capable of detecting lncap cells was linked to myristilated chitosan nanogels (apt-mcs) by glutaraldehyde and loaded wi...
