Dichloridobis(pyridine-2-selenolato-κ2N,Se)tin(IV)

Thermal reaction of a (hydrido)(selenolato)platinum(II) complex having a dibenzobarrelenyl group leading to three cyclometalations.

The thermal reaction of a (dibenzobarreleneselenolato)(hydrido)platinum(ii) complex gave two four-membered selenaplatinacycles, one of which is formed by hydroplatination of the Pt-H bond to the etheno bridge and the other is a vinylic C-H bond activation product, and a five-membered selenaplatinacycle formed by an aromatic C-H bond activation.

تعیین غلظت کریپتوفیکس 2، 2، 2 در رادیوداروی [18F]FDG

غلظت کریپتوفیکس 2،2،2 در محلول‌های [18F]FDG و استانداردهای کریپتوفیکس 2،2،2 به دو روش آشکارسازی (ترکیب کریپتوفیکس 2،2،2) با بخار ید و معرف یدوپلاتینات تعیین شد. در هر دو روش، تفاوت غلظت محلول‌های کریپتوفیکس، به صورت تفاوت در شدت رنگ لکه‌های آشکار شده بر روی TLC نمایان شد. حد تشخیص کریپتوفیکس با بخار ید و معرف یدوپلاتیتات به ترتیب ppm25 و ppm2 می‌باشد. هر دو روش را می‌توان برای پذیرش ...

In this paper, we proposed a new, highly scalable method to solve the database selection problem when the number of local databases in a metasearch engine is very large. For single-term queries, this method guarantees all desired documents to be retrieved. Experiments were conducted to show that this method is very eeective for typical short Internet queries. We also illustrated that the our da...

braiding from 2-groups to 2-groupoids

we give the concept of ‘braiding’ for 2-groupoids, and we show that this structure is equivalent tobraided regular, crossed modules.
