Maximum Power Point (MPP) tracker has an important role in the performance of fuel cell (FC) systems improvement. Tow parameters which have effect on the Fuel cell output power are temperature and membrane water. So contents make the MPP change by with variations in each parameter. In this paper, a new maximum power point tracking (MPPT) method for Proton Exchange Membrane (PEM) fuel cell is pr...

This paper deals with the problem of the cell size determination in WCDMA based mobile networks, in multiservice environments. The objective is to obtain the maximum cell size, given a set of services with their corresponding constraints, in terms of Quality of Service (QoS), binary rate, etc. To achieve this, we have to find the optimal services’ load factors which maximizes the cell radius of...

BACKGROUND Initiation of antiretroviral therapy during primary human immunodeficiency virus (HIV)-1 infection may confer long-term benefit. METHODS After initiation of zidovudine, lamivudine, abacavir, and amprenavir therapy in patients in the QUEST cohort, predictors of virological outcome, virological and immunological changes, and adverse events were evaluated over 48 weeks. RESULTS One ...

OBJECTIVE This study aimed to detect and quantify the HIV-1 viral load in ranula fluid of HIV-positive patients. STUDY DESIGN Fourteen HIV-positive patients (13 not on highly active antiretroviral therapy) presenting with ranulas were prospectively evaluated. The viral load in the ranula fluid was quantified, and the results were correlated with CD4(+) cell count and viral load in the patient...

The expression of a foreign protein(s) in a recombinant host cell or organism often utilizes a significant amount of the host cell's resources, removing those resources away from host cell metabolism and placing a metabolic load (metabolic drain, metabolic burden) on the host. As a consequence of the imposed metabolic load, the biochemistry and physiology of the host may be dramatically altered...

Load cells are transducers used to measure force or weight. Despite the fact that there is a wide variety of load cells, most of these transducers that are used in the weighing industry are based on strain gauges. In this paper, an s-beam load cell based on strain gauges was suitably assembled to the mechanical structure of several seats of a bus under performance tests and used to measure the ...

The intelligent energy management system is operated automatically to ON and OFF the generating sources as per the load demand. The renewable energy sources used in this energy management system are solar, wind, fuel cell and energy storage element battery as an input source. These renewable energy sources are integrated into the main dc bus through dc-ac converter. Microgrid is basically a gro...
