———————————————————————————————— ————————————————————————————————— 3 Abstract An analytical technique to combine TLC with MS was developed. The initial study was carried out on a graphite plate, which functions as a photon absorbing material. A continuous wave diode laser replaced traditional pulsed lasers as the desorption source, which was employed for this purpose for the first time. The the...

the main goal of the present study is to identify characteristics of the inter-station horizontal magnetic responses and the vertical magnetic data, as two types of magnetotelluric transfer functions, in the modeling procedure. through consideration of model responses and two-dimensional inversion of synthetic data, sensitivity of the data components in detecting different geophysical structure...

background: the aim of this study was to evaluate the protein spots of excre-tory - secretory products of fasciola hepatica using two dimension electrophoresis method in the presence and absence of triclabendazole drug which can be consid-ered to detect the target protein of the drug. methods: f. hepatica parasites were collected from infected cattle livers, divided in two groups and cultivated...

‎‎a natural generalization of two dimensional cyclic code ($t{tdc}$) is two dimensional skew cyclic code‎. ‎it is well-known that there is a correspondence between two dimensional skew cyclic codes and left ideals of the quotient ring $r_n:=f[x,y;rho,theta]/_l$‎. ‎in this paper we characterize the left ideals of the ring $r_n$ with two methods and find the generator matrix for two dimensional s...

introduction two-dimensional gel electrophoresis (2dge) is a powerful technique in proteomics for protein separation. in this technique, spot segmentation is an essential stage, which can be challenging due to problems such as overlapping spots, streaks, artifacts and noise. watershed transform is one of the common methods for image segmentation. nevertheless, in 2dge image segmentation, the no...

A temporal logic of causality (TLC) was introduced by Alur, Penczek, and Peled in [1]. It is basically a linear time temporal logic interpreted over Mazurkiewicz traces which allows quantification over causal chains. Through this device one can directly formulate causality properties of distributed systems. In this paper we consider an extension of TLC by strengthening the chain quantification ...

I would like to thank Pedone et al 1 for their recent article in CHEST (April 2012). The article presented data on the association between pulmonary restriction, properly defi ned as having a total lung capacity (TLC) below the fi fth percentile of the reference population (lower limit of normal [LLN]), and all-cause mortality. As the authors correctly pointed out, defi ning restriction as FVC ...

this research is carried out to design and manufacturing of lathe vibration tool and their tests. firstly, one-dimensional vibration tool is designed and made of the bending vibration mode. one-dimensional vibration tool with half piezoelectric rings is considered to excite the bending mode of tool. structure of vibration tool is designed in abaqus software about 20 khz and then is made with re...

BACKGROUND We developed a simple and inexpensive thin-layer chromatography (TLC) assay for semiquantitative detection of saliva concentrations of nevirapine in resource-limited settings. The method was validated in an African target population. METHODS Paired plasma and saliva nevirapine concentrations were assayed by high-performance liquid chromatography (HPLC); saliva concentrations of nev...
