We study the breakdown of the magnetization plateau at the magnetization M = MS/3 (MS is the saturation magnetization) of the S = 1/2 anisotropic spin chain with ferromagnetic-ferromagnetic-antiferromagnetic interactions. We consider the model with the isotropic ferromagnetic (trimer) coupling JF , and anisotropic antiferromagnetic coupling (Jx = Jy = JAF and Jz = ∆JAF ). For the limit of large...

Glacial retreat on the Tibetan Plateau and surrounding regions is characteristic since the 1960s and has intensified in the past 10 yr. The magnitude of glacial retreat is relatively small in the interior of the Tibetan Plateau and increases to the margins of the plateau, with the greatest retreat around the edges. Glacial retreat in this region is impacting the hydrological processes in the Ti...

The Shillong Plateau (northeastern India) constitutes the only significant topography in the Himalayan foreland. Knowledge of its surface uplift history is key to understanding topographic development and unraveling tectonic–climate–topographic coupling in the eastern Himalaya. We use the sedimentary record of the Himalayan foreland basin north of the Shillong Plateau to show that the paleoBrah...

The posterior slope of the tibial plateau is an important feature to preserve during knee replacement. The correct slope aids in the amount of flexion and determines if the knee will be loose on flexion. This is a study on the posterior tibial plateau slope based on preoperative and postoperative radiographs of 100 consecutive patients who had total knee replacements. The average posterior slop...

demineralized bone matrix has been successfully commercialized as an alternative bone graft material that not only can function as filler but also as an osteoinductive graft. numerous studies have confirmed its beneficial use in clinical practice. heterotopic ossification after internal fixation combined with the use of demineralized bone matrix has not been widely reported. in this paper we de...

an amalgamation of ancient mythological and linguistic features from ghabrestan tepe, this article is disposed to introduce some of the oldest findings especially about the then prevailing myths. it can possibly be said that the oldest motifs carved by men, on bones, stones or on cave walls have been the depictions of myths related to homo sapiens; however, even after the lapse of thousands of ...

Although epidemiologic studies of tibial plateau fractures have been conducted, none have included geographically defined populations or a validated fracture classification based on computed tomography (CT). The goals of this study were to provide up-to-date information on the incidence and basic epidemiology of tibial plateau fractures in a large unselected patient population and to report the...

Evapotranspiration (ET) is a key process of the climate system because it links water, energy and carbon cycles. In this study we modified a Penman–Monteith based algorithm to estimate ET on the Tibetan Plateau at a 1-km spatial resolution for the period 2000–2010 using meteorological and satellite remote sensing data. The results showed that the average annual ET on the Tibetan Plateau was 350...

1. The present study sought to determine the possible existence of a pool of proteins which turn over with life-time kinetics. The pattern of enrichment of ammonia and urea in hourly samples of urine was determined in normal adults to whom oral doses of [15N]glycine were given hourly for 36 h. The subjects received hourly meals throughout, and in six the study commenced at 06.00 hours, in five ...

tepe sagzabad, a site situated on the qazvin plain of north-central iran, was excavated from 1970 to 1998 by the institute ofarchaeology of tehran university. recent excavations by h. tala’i (1997-1999) yielded some metal artifacts dating to theearly iron age. ten of these copper-based samples were investigated using inductively coupled plasma optical emissionspectroscopy (icp-oes), scanning el...
