Siswa dituntut harus menjadi pemecah masalah yang handal dalam berbagai situasi, salah satunya ill-structured problems. Penelitian ini merupakan study kasus bertujuan untuk mendeskripsikan penyebab kegagalan RZ memecahkan problems tentang persegi panjang menginvestigasi secara mendalam, proses, aktivitas subjek RZ. diminta kemudian dilakukan wawancara mendalam. Hasil penelitian menunjukkan bahw...

Tularemia is a potentially fatal disease caused by the Category A bioterrorism agent Francisella tularensis. Aminoglycosides, fluoroquinolones, and tetracyclines can be used to treat tularemia; however, there high incidence of relapse treatment failures when using these drugs. Furthermore, no tularemia vaccine licensed for use in United States. Therefore, new antibiotics that target F. tularens...

Root lesions may affect both dorsal and ventral roots. However, due to the possibility of generating further inflammation and neuropathic pain, surgical procedures do not prioritize the repair of the afferent component. The loss of such sensorial input directly disturbs the spinal circuits thus affecting the functionality of the injuried limb. The present study evaluated the motor and sensory i...

It is well known that only a special class of bandpass signals, called real-zero (RZ) signals can be uniquely represented (up to a scale factor) by their zero crossings, i.e., the time instants at which the signals change their sign. However, it is possible to invertibly map arbitrary bandpass signals into RZ signals, thereby, implicitly represent the bandpass signal using the mapped RZ signal'...

Influence of topographical features on mechanical properties of 0.1 wt % Multi-Layer Graphene (MLG)/clay-epoxy nanocomposites has been studied. Three different compositions were made: (1) 0.1 wt % MLG-EP; (2) 0.1 wt % clay-EP and (3) 0.05 wt % MLG-0.05 wt % clay-EP. The objective of making hybrid nanocomposites was to determine whether synergistic effects are prominent at low weight fraction of...

Dent's disease is an X-linked inherited disorder characterized by hypercalciuria, nephrocalcinosis, nephrolithiasis, low molecular weight proteinuria, Fanconi's syndrome, and renal failure. It is caused by inactivating mutations in CLC5, a member of the CLC voltage-gated chloride channel family. CLC5 is known to be expressed in the endosomal compartment of the renal proximal tubule, where it ma...

Types of Modulation. Figure 7.1 illustrates two alternative ways to generate a modulated optical signal. In Fig. 7.1 (a), the laser is turned on and off by modulating its current; this method is known as direct modulation. In Fig. 7.l(b), the laser is on at all times, a so-called continuous wave (CW) laser, and the light beam is modulated with a kind of optoelectronic shutter, a so-called modul...

In this chapter, the performance improvement obtained from phase modulation (PM) and filtering on return-to-zero (RZ) signal format at the transmitter is investigated. The primary purpose is to understand the mechanism of each type of PM that leads to performance improvement relative to the RZ signal format with no PM. Three types of phase modulation on an RZ pulse train are considered in this ...

And therefore, z λ < λ < λz and rz = λz/λ>1 and r z = z λ /λ <1. In this paper, we attempt to improve on the upper level set (ULS) scan system by improving the nodal quality and quantity of the upper level set tree, using PULSE, the progressive upper level set scan system. Here we generalize the ULS notion of the rank of a cell, while the original ULS algorithm ranked cells only by a single res...
