ADP-ribosylation factor (ARF) proteins and inhibitory peptides derived from ARFs have demonstrated activities in a number of in vitro assays that measure ER-to-Golgi and intra-Golgi transport and endosome fusion. To better understand the roles of ARF proteins in vivo, stable cell lines were obtained from normal rat kidney (NRK) cells transfected with either wild-type or a dominant activating al...

Hydrate-based gas separation is often investigated using batch or semi-batch operations. To increase the throughput of mixture without increasing apparatus volume, it preferable to perform a continuous operation hydrate-based separation. Therefore, we proposed flow-type for performing formation with passing gaseous and subsequently decomposition hydrate particles. Characteristics multiple fluid...

Quantized detector networks (QDN) deals with quantum information exchange between observers and their apparatus rather than with systems under observation. Partial observations in QDN involve subsets of the elementary signal detectors which constitute an apparatus. We use them to prove that QDN is consistent with Einstein locality and violations of Bell-type inequalities. PACS numbers: 03.65.-w...

We have constructed an atom interferometer of the Mach-Zehnder type, operating with a supersonic beam of lithium. Atom diffraction uses Bragg diffraction on laser standing waves. With first order diffraction, our apparatus has given a large signal and a very good fringe contrast (74%), which we believe to be the highest ever observed with thermal atom interferometers. This apparatus will be app...

Diagnostic X-ray equipment was used to develop an experimental apparatus for calibrating a CdTe detector. Powder-type samples were irradiated with collimated X-rays. On excitation of the atoms, characteristic X-rays were emitted. We prepared Nb2O5, SnO2, La2O3, Gd2O3, and WO3 metal oxide samples. Experiments using the diagnostic X-ray equipment were carried out to verify the practicality of our...

One year's experience with a new type of oxygen concentrator and anaesthetic machine, designed for anaesthesia in developing countries, is presented. The apparatus, its performance and problems are described and the author's suggested modifications to improve the original design are outlined. The apparatus, with these changes, represents a significant advance in oxygen availability for hospital...

This article describes the case of a 62-year-old patient who developed an erosive nodular mass on the nail apparatus after receiving a trauma during a hunting incident. The lesion was initially diagnosed as an amelanotic melanoma of the nail apparatus, illustrating the fact that this type of lesion is often misdiagnosed – up to 85% of the time if the physician lacks dermatological expertise –an...

The chemical composition of the essential oil obtained from aerial parts of Galium verum L. (Rubiaceae) from Iran was examined by a combination of GC and GC/MS. The oil isolated by hydro-distillation using a Clevenger-type apparatus. Air-dried aerial parts of Galium verum (80 g) which were collected from Bomehen in Tehran province at full flowering stage on May 2003, were subjected to hydro-dis...

The leaves of Arum conophalloides (Araceae) were used in some west areas of Iran as a dessert. The aerial parts of the herb were collected from Sahneh Mountains, Kermanshah Province, West of Iran and was hydrodistilled by Klevenger-type apparatus. Composition of the essential oil was determined by GC and GC/MS. Totally, 18 components (92% of total essential oil) were identified. The oil contain...
