The bifurcation diagram of a truncation to six degrees of freedom of the equations for quasi-geostrophic, baroclinic ow is investigated. Period doubling cascades and Shil'nikov bifurcations lead to chaos in this model. The low dimension of the chaotic attractor suggests the possibility to reduce the model to three degrees of freedom. In a physically comprehensible limit of the parameters this r...

In this study, 90 patients with idiopathic non-allergic rhinitis were divided into three groups. Silver nitrate was given to Group I, flunisolide to Group II, and placebo to Group III. Healing results according to symptoms, physical findings, nasal smear findings and biopsy findings were compared. Improvement ws noticed in symptoms (rhinorrhea 93%, sneezing 89%, nasal congestion 80%), physical ...

1 Introduction Plastocyanin (PC) is a small (M r 10 500), 'blue' copper protein which transfers electrons from cyto-chrome / to the primary electron donor of photosystem I (P700) in the photosynthetic electron transport chain. It reacts rapidly with cytochrome / in vitro and also with several other cytochromes, although somewhat more slowly [1].. The crystal structures of both oxidized and redu...

Hematopoietic stem cell transplantation (HSCT) is a lifesaving expensive medical procedure. Hence, more transplants are performed in more affluent countries. The impact of economic factors on patient outcome is less defined. We analyzed retrospectively a defined cohort of 102,549 patients treated with an allogeneic (N = 37,542; 37%) or autologous (N = 65,007; 63%) HSCT. They were transplanted b...

Physics is one of highly difficult material study, so student tend to have low study motivation. This research aims enhance motivation also describe the feasibility and practicality using Whiteboard Animation first grade senior high school towards impulse momentum. Method this Research Development (R&D) with 4D models (Define, Design, Develop, Disseminate). was conducted untill test learnin...

We aimed to analyze genotypes of VEGF-A, VEGFR2, Flt4, PDGFRα, HIF-1α and ERCC1 and their correlation with thymic tumor risk and patient outcome. DNA of 57 consecutive patients (43 thymomas and 14 thymic carcinomas) who underwent total thymectomy at our Institution was extracted from paraffin-embedded tissue. We selected polymorphisms in the following genes:HIF1-α (rs2057482T > C, rs1951795A > ...

BACKGROUND Fluoroquinolones are broad-spectrum antibiotics widely used in the treatment of bacterial infections such as Staphylococcus aureus isolates. Resistance to these antibiotics is increasing. MATERIAL/METHODS The occurrence of mutations in the grlA and gyrA loci were evaluated in 69 fluoroquinolone-resistant S. aureus isolates from 2 teaching hospitals of Tehran University of Medical S...

Ozonation is increasingly applied in water and wastewater treatment for the abatement of micropollutants (MPs). However, transformation products formed during ozonation (OTPs) their fate biological or sorptive post-treatments largely unknown. In this project, a high-throughput approach, combining laboratory experiments detection by liquid chromatography high-resolution mass spectrometry (LC-HR-...

In recent months I have come across many instances in which someone has found what they believe is a new result, in which they evaluate in closed form a sum involving binomial coefficients or factorials. In each case they have managed to do that either by using the recent powerful method of Wilf and Zeilberger (the W–Z method) [6], or by comparing coefficients in some ad hoc algebraic identity....
