The three-dimensional cuboids packing is NP-hard and finds many applications in the transportation industry. The problem is to pack a subset of cuboid boxes into a big cuboid container such that the total volume of the packed boxes is maximized. The boxes have no orientation constraints, i.e. they can be rotated by 90◦ in any direction. A new heuristic algorithm is presented that defines a conc...

Solar cells manufactured on boron-doped Czochralski-grown silicon (Cz-Si) degrade in performance when exposed to light or minority carriers are injected in the dark until a stable efficiency is reached. This effect, which is now known for almost 30 years, is due to the activation of a specific metastable defect in the Cz-Si material. Although a conclusive explanation of the effect is still to b...

This study addressed the possibility of forming of co-amorphous systems between clozapine (CZ) and various carboxylic acid plasticizers (CAPs). The aim was to improve the solubility and oral bioavailability of clozapine. Co-amorphous dispersions were prepared using modified solvent evaporation methodology at drug/plasticizer stoichiometric ratios of 1:1, 1:1.5 and 1:2. Solid state characterizat...

We have argued that the capture-zone distribution (CZD) in submonolayer growth can be well described by the generalized Wigner distribution (GWD) PðsÞ 1⁄4 asβ expð bsÞ, where s is the CZ area divided by its average value. This approach offers arguably the most robust (least sensitive to mass transport) method to find the critical nucleus size i, since β iþ2. Various analytical and numerical inv...

PURPOSE To analyze the latency and amplitude of P300 responses obtained with electrodes positioned at Cz and Fz and in different tasks of infrequent stimulus identification in normal hearing individuals. METHODS Forty adults of both genders participated in the study. Three recordings with three different tasks were obtained for the identification of the infrequent stimulus; simultaneous recor...

A fracture expansion criterion of hydraulic fracturing was suggested to deal with the hard and stable roof control in coal mines. An experiment designed for control, reliability model verified. Four different types holes technology were setup room, a fully mechanized caving face implemented.

The localization and termination of olivocerebellar fibers in the flocculus and nodulus of the rabbit were studied with anterograde axonal transport methods [wheatgerm agglutininhorseradish peroxidase (WGA-HRP) and tritiated leucinel and correlated with the compartments in the white matter of these lobules delineated with acetylcholinesterase histochemistry (Tan et al. J. Comp. Neurol., 1995, t...

A fundamental evolution equation is developed to describe the distribution of areas of capture zones (CZs) associated with islands formed by homogeneous nucleation and growth during submonolayer deposition on perfect flat surfaces. This equation involves various quantities which characterize subtle spatial aspects of the nucleation process. These quantities in turn depend on the complex stochas...

In an open randomized multicenter comparative study, we evaluated the safety and efficacy of cefepime (CP; 2.0 g given intravenously every 12 h) and ceftazidime (CZ; 2.0 g given intravenously every 8 h) as initial treatment for adult patients with suspected serious bacterial infections. A total of 133 patients entered the study, of whom 114 were evaluable for clinical and microbiological respon...
