a convenient liquid chromatographic-single quadrupole mass spectrometric (lc-ms) method was developed and validated for dexchlorpheniramine maleate (inn name: chlorphenamine) determination in human plasma. the need for just a single liquid-liquid extraction with ethyl acetate and being highly sensitive were the advantages of this method. the linearity was also excellent over the range of 1 to 1...

The three-dimensional collagen framework of human liver parenchyma in surgical specimens from patients with chronic active hepatitis (CAH), viral or alcoholic cirrhoses (LC) was observed by scanning electron microscopy after cell-maceration by the method of Ohtani (1988). In control livers, the tubular sheaths of collagen fibers housing the sinusoid were shown to form a labyrinthine network, wh...

We examine the performance of multiple description coding (MDC) with and without the use of automatic repeat request (ARQ) protocols for packet network communication, in comparison with layered coding (LC). The rate-distortion lower bound of MDC and LC are incorporated into an E-model based performance measure, which accounts for the additional costs of excess rates and delay incurred from usin...

This paper aims to study a 3 kW wireless power transfer system for electric vehicles. First, the LCL-LCL topology and LC-LC series topology are analyzed, and their transfer efficiencies under the same transfer power are compared. The LC-LC series topology is validated to be more efficient than the LCL-LCL topology and thus is more suitable for the system design. Then a novel q-Zsource-based onl...

background methotrexate is a folic acid antagonist that has been in clinical use for five decades. its use in patients with brain tumors is primarily confined to primary central nervous system lymphoma (pcnsl), in which it is the cornerstone of chemotherapy. objectives a selective and sensitive high-performance liquid chromatography-electrospray ionization-mass spectrometry method was developed...

since its introduction in 1988, laparoscopic cholecystectomy (lc) has become the procedure of choice in the management of gallstone disease. it has well established advantages compared to its traditional open counterpart such as reduction in hospital stay and related costs, more rapid return to work, and reduction in pain and cosmetic problems. lc, like any other procedure, has its own indicati...

BACKGROUND Lung cancer (LC) is often diagnosed late when curative intervention is no longer viable. However, current referral guidelines (e.g. UK National Institute for Health and Care Excellence guidelines) for suspected LC are based on a weak evidence base. Aim. The purpose of this systematic review is to identify symptoms that are independently associated with LC and to identify the key meth...

This paper describes the guidelines we followed and the requirements we stated while designing and implementing the CORBA Lightweight Components (CORBA–LC) Component Model. CORBA–LC is a lightweight distributed reflective component model based on CORBA. Instead of using a traditional client/server model, it imposes a peer network model in which the whole network act as a repository for managing...

A feasible alternative x is a strong Condorcet winner if for every other feasible alternative y there is some majority coalition that prefers x to y. Let LC (resp., ℘C) denote the set of all profiles of linear (resp., merely asymmetric) individual preference relations for which a strong Condorcet winner exists. Majority rule is the only non-dictatorial and strategy-proof social choice rule with...
