Unitarity constraints on neutral pion electroproduction

At large virtuality $Q^2$, the coupling to the vector meson production channels provides us with a natural explanation of the surprisingly large cross section of the neutral pion electroproduction recently measured at Jefferson Laboratory, without destroying the good agreement between the Regge pole model and the data at the real photon point. Elastic rescattering of the $\pi^0$ provides us with a way to explain why the node, that appears at $t\sim -0.5$ GeV$^2$ at the real photon point, disappears as soon as $Q^2$ differs from zero.Comment: 7 pages; 12 figures Figures 1, 2, 10, 11, 12 updated.

A PHYTOPHARMACOLOGICAL REVIEW ON ARID REGION MEDICINAL PLANT- AERVA PSEUDOTOMENTOSA

Aerva pseudotomentosa Blatt. & Hallb. (Amaranthaceae) is arid region plant of Amaranthaceae family. It is commonly known as Bui. It is used in folk medicine for the treatment of various ailments such as pain and inflammatory hyperalgesic disorders, rheumatic pain, fever, treatment of wounds and urinary disorders. Aerva pseudotomentosa is a valuable ethnovetrinary medicine to treat health ailments of live stock. Aim of current review to search literature for ethnomedicinal use, pharmacological property, safety/toxicity study, pharmacognostic and physicochemical standardization, preliminary phytochemical investigation of Aerva pseudotomentosa. This compiled data will enable the researchers to identify and differentiate the plant Aerva pseudotomentosa from other similar aerva species and to explore the medicinal properties of different parts of this desert vegetation which are yet to be discovered

Macroscopic quantum effects of electromagnetic induction in silicon nanostructures

At room temperature, a macroscopic quantum galvanomagnetic effect of Faraday electromagnetic induction was demonstrated under conditions of the capture of single magnetic flux quanta in the edge channels, confined by chains of negative-U centers, in a silicon nanostructure heavily doped with boron, prepared in Hall geometry on an n-type Si (100) substrate. It is shown that this effect leads to the appearance of an induction current when only a constant magnetic field is applied in the absence of an externally applied voltage or a stabilized current.Comment: 14 pages, 5 figure

Ileocecal reservoir reconstruction after total mesorectal excision: functional results of the long-term follow-up

Background: The aim of this study is to obtain functional results of the long-term follow-up after TME and ileocecal interposition as rectal replacement. Methods: The study included patients operated on between March 1993 and August 1997 who received an ileocecal interposition as rectal replacement. Follow-up was carried out 3 and 5 years postoperatively. For statistical analysis, the paired t-test, rank test (Wilcoxon), and chi-square or Fisher's exact test were applied; level of significance, P<0.05. Results: Forty-four patients were included in the studies. Of these, five were not available and four patients could not be evaluated (dementia 1, radiation proctitis 1, fistula 1, pouchitis 1). Seventeen patients died during the observation period; 12 died of the disease. Recurrence of the disorder occurred in 2 of 35 patients (5.7%); 26 and 18 patients, 3 and 5 years postoperatively, respectively remained in the study. At 5 years, 78% of the patients were continent; mean stool frequency was 2.5±1.6 per day. Conclusions: Functional results and subjective assessment of ileocecal interposition were constant at 3 and 5 years postoperatively. If construction of a colonic J-pouch is not possible due to lack of colonic length, especially after prior colonic resections, the ileocecal interpositional reservoir may offer an alternative to rectal replacemen
