according to the global fuel crisis, it seems necessary to use alternative fuel instead of gasoline. since the natural gas is cheaper, have higher frequency than gasoline and less pollution, it is a suitable fuel. many efforts have been done in order to replace gasoline with natural gas. one of the methods is to inject natural gas and gasoline fuel simultaneously and to use the benefits of both...

Replication of coxsackievirus B3 occurred for days in cultures of murine neonatal skin fibroblasts in the absence of cytopathology and resulted in alteration of the plasma membrane. Dual immunofluorescence studies showed that the lectin Ulex europaeus agglutinin I bound only to cells producing viral capsid antigens. Cultures of coxsackievirus B3-inoculated murine neonatal skin fibroblasts showe...

We report a single-layer frequency selective dual band reflectarray operated at 28 and 39GHz simultaneously. The consists of cross dipole spiral elements aligned on the surface substrate surfaces rear side. that can control reflection direction same plane substrate, resulting in simultaneous dual-band up to ±30° independently. Furthermore, showed higher transmittance frequencies except for targ...

Three hundred and sixty samples of blood from 230 hospital patients were examined and compared with the results of simultaneous blood culture to determine the value of buffy-coat microscopy in detecting bacteraemia. One observer found 86 positive smears, 12 of which were from patients with positive blood cultures and 74 from patients with negative blood cultures. The buffy-coat smear was negati...

Papillomaviruses have been reported to be very difficult to grow in cell culture. Also, there are no descriptions of cell cultures from lesions of bovine cutaneous papillomatosis, with identification of different bovine papilloma virus (BPV) DNA sequences. In the present report, we describe primary cell cultures from samples of cutaneous lesions (warts). We investigated the simultaneous presenc...

The article discusses Russian scholars’ approaches to studying the fluid nature of national identity in postcolonial writing. key factor uniting vast research area literature is writers’ intention project process transformation, consolidate and review shifts caused by interaction cultures. analysis data suggests that researchers share a common objective identifying influence single historical c...

abstract  in order to study f3´5´h and f3´h function and their intraction in the grapevine flavonoids biosynthetic pathway, designing and constraction of suitable constructs encoding ihprna was performed and transgenic lines containing silencing construct of f3´h and simultaneous silencing construct of f3´5´h and f3´h were created. for this purpose, fragments were selected from both genes and i...

Polygalacturonases (PG; EC 3.2.1.15) catalyze the hydrolysis of pectin and/or pectic acid and are useful for industrial applications such as juice clarification and pectin extraction. Growth and heterologous expression of recombinant Saccharomyces cerevisiae which expresses an acidic PG from Aspergillus kawachii has been studied in batch and fed-batch cultures. Kinetics and stoichiometric param...

OBJECTIVE To introduce and evaluate the safety of a novel dual-sided electrosurgery handpiece design for simultaneous tissue cutting and coagulation. METHODS We designed a prototype double-sided handpiece allowing automatic switching between two electrodes with a simple handpiece flip. The concept of the system as a surgical instrument was assessed by an animal experiment. RESULTS The skin ...
