in this paper, lagrangian and equations describing one-dimensional anisotropic non-heisenberg model are studied. in this study we used the generalized coherent states in real parametrizations and the feynman path integral for these states in su(3) group. these equations describe nonlinear dynamics of non-heisenberg ferromagnetic chain completely. solutions of these equations are magnetic solito...
Within the semibosonized SU(3)-NJL model the mass splittings of baryons and the axial vector coupling constants of the nucleon are evaluated. The mass splittings of the hyperons are reproduced with great accuracy if second order corrections in ms are taken into account. email:[email protected] email:[email protected] email:[email protected]
address inclusive education and, increasingly, distance education is seen as a flexible and appropriately inclusive way to deliver such courses. In this article a team of colleagues, Kieron Sheehy, Jonathan Rix, Melanie Nind and Katy Simmons, discusses the development of an Open University course, E243 Inclusive Education: Learning from Each Other, which was launched in February 2004. The team ...
Mobilization of As from geological materials into ground and drinking water sources may represent an important threat to human health. The objective of this study was to assess the As concentration and availability in underground water used as drinking water sources. Water samples were collected from public and private wells in Timis-Bega area of Pannonian Basin, West Romania. Total-dissolved A...
Cuatro Cienegas basin (CCB) is a biodiversity reservoir within the Chihuahuan desert that includes several water systems subject to marked seasonality. While several studies have focused on biodiversity inventories, this is the first study that describes seasonal changes in diversity within the basin. We sampled Pseudomonas populations from a seasonally variable water system at four different s...
Alfalfa is an autotetraploid, allogamous and heterozygous forage legume, whose varieties are synthetic populations. Due to the complex nature of the species, information about genetic diversity of germplasm used in any alfalfa breeding program is most beneficial. The genetic diversity of five alfalfa varieties, involved in progeny tests at Institute of Field and Vegetable Crops, was characteriz...
Basin morphometry is a means of numerically analysing or mathematically quantifying different aspects of a drainage basin. In the present study, morphometric analysis of the Baitarani basin has been carried out using earth observation data and geographical information system (GIS) techniques. The morphometric parameters considered for analyses include the linear, areal and relief aspects of the...
چکیده سنجش طیف یکی از بخش های مهم رادیو شناختی می باشد که در این بخش و در طول زمان سنجش، یک su جهت عمل حس گری باید به طور موقت ارسال داده خود را متوقف کند و به پیدا کردن باندهای خالی کمک کند. واضح است که هر چه تعداد suهای شرکت کننده در سنجش طیف بیشتر باشند، احتمال یافتن حفره های خالی بیشتر می شود و دقت حس گری بالا می رود. ولی با توجه به این که همین suهای انتخاب شده در طول زمان عمل حس گری نمی ت...
The Mediterranean Sea is a marine biodiversity hot spot. Here we combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marine ecosystem and to revise and update several species lists. We also assessed overall spatial and temporal patterns of species diversity and identified major changes and threats. Our results listed approx...
The campaign of opposition to MX missile deployment in the Great Basin of Nevada and Utah stands as a unique case of grassroots mobilization, because it took place in a region whose inhabitants both supported a strong U.S. military defense posture and considered the decision-making processes of foreign policy and national security remote to their overall concerns. This study holds that the two ...
