    Opis:
    Marine biodiversity of Papua is very high, but unfortunately research and utilization in medicine are limited. Many species of flora and fauna are used in ethopharmacology as drugs but without scientific explanation, e.g. octopus (Octopus cyanea), found in the Northern Papua Sea. The aim of this research was to test the toxicity of the ethanol octopus ink. The toxicity was tested with the Brine Shrimp Lethality Test (BSLT) method. The samples were collected from the sea of Biak island in West Papua, extracted with ethanol, ethyl acetate, and dichloromethane then tested the toxicity for Artemia salina leach larvae. The toxicity test involved concentrations of 1000, 750, 500, 250, 100, 75, 50, and 25 ppm. The result showed that ethanol extract of octopus ink has LC50 of 290 ppm, ethyl acetate extract has LC50 of 947 ppm, whereas dicholoromethane extract – 2190 ppm.

    Opis:
    In this paper we discuss the line shapes of a two-level atom in the presence of broad-band squeezed vacuum and collisional broadening. We describe the collisions and the squeezed vacuum using a stochastic model of Rabi amplitude fluctuations. From such a stochastic description the fast and the slow damping rates of the Bloch polarizations are obtained. The strong field resonance fluorescence spectrum in the presence of stochastic broad-band squeezed vacuum and collisions is derived.

    Opis:
    Multiple anthropogenic agents have turned Lake Maracaibo into a hypereutrophic environment. Heavy metals resulting from the steel and oil industry augment pollution in the lake. There is a lack of research on the ecotoxicological effect of heavy metals in protozoa. To evaluate the ecotoxicological effect of Cr 3+ , Cr6+ , Cd2+ , Pb2+ and Ni2+ on free-living ciliated protozoa and to identify suitable ciliated protozoa candidates for bioindicators of water quality; we estimated the lethal concentration for 50% of the protozoa population (LC50 ) in samples from two stations (S1 : narrow of Maracaibo and S2 : South of the lake) using ecotoxicological tests in the Sedgewick–Rafter chamber and Probit analysis. The general toxicity patterns obtained for S1 protozoa (Euplotes sp. and Oxytricha sp.) were Cr3+ > Cd2+ > Pb2+ > Cr6+ > Ni2+ ; and those corresponding to S2 (Coleps sp. and Chilodonella sp.) were Cr6+ > Cr3+ > Cd2+ > Pb2+ >Ni2+. We found statistically significant difference (p < 0.05) in the LC50 of protozoa exposed to Cr3+, Cr6+, Ni2+ and Pb2+ when comparing the two sampling stations. The differences observed in toxicity patterns are probably the result of various kinds of protozoa adaptation, possibly induced by various sources, levels and incidents of exposure to heavy metals contamination of the protozoa studied and to the physicochemical conditions prevailing in the two selected stations. The levels of tolerance observed in the present study, allow us to infer that S2 ciliates are the most susceptible to the contaminants studied and can be used as possible microbiological indicators that provide early warning in studies of contamination by heavy metals in Lake Maracaibo.

    Quantum mechanical arguments show that any optical amplifier must add noise to the amplified beam of light. For the case of a high gain amplifier with a coherent (Poissonian) input, the signal-to-noise ratio of the amplified beam must be at least two times smaller than that of the incident beam. We review the theoretical basis of this prediction. We also describe the results of our experimental investigations of the noise properties of optical amplifiers that utilize the nonlinear optical response of strongly driven atomic transitions.

    Opis:
    A decoherence problem is discussed by means of quantum continuous measurement theory. It is shown that the conditional state of quantum system interacting with a bath preserves its initial purity. In this presentation decoherence arises as a result of averaging over the stochastic times of reduction moments ("clicks"). A method based on external phase feedback is proposed to slow down the decoherence of field superposition state in an open optical cavity. It is also shown that an atom placed inside the optical cavity plays a role of internal self-organized positive feedback between field and atom, which leads to an exponential increase in the mean dipole moment of the atom for the field initially prepared in a superposition of coherent states, i.e. to quantum instability.

    A detailed stability analysis is performed for a highly excited semiconductor modelled as an exciton-electron-hole-photon system driven externally by optical pumping. Chaotic self-pulsations are shown to occur on both the upper and lower branches of the bistable steady state curve of the system via a sequence of period-doubling oscillation process. Such a route to chaos is well known in laser physics and in other nonlinear systems but not in highly excited semiconductors yet.

    Opis:
    PbWO₄ crystal-Hamamatsu S8148 avalanche photodiode (APD) assembly has been used in the barrel section of the CMS electromagnetic calorimeter. The shot noise of the photodiode is one of the important parameters for the energy resolution of the crystal-APD system. The major source of this noise is the statistical variations in the rate at which primary charge carriers are generated and recombine. Thus, the shot noise varies with position of the primary charge carriers generated in photodiode. In this work, the shot noise properties of the Hamamatsu S8148 APD structure and zinc sulfide-silicon (ZnS-Si) isotype heterojunction APD structure have been compared for the PbWO₄ photons. Calculations were made with a Single Particle Monte Carlo simulation technique.

    Spontaneous decay of excited cold atoms into a cavity can drastically affect their translational dynamics, namely, atomic reflection, transmission and localization at the interface. We show that the quantum Zeno effect on excitation decay of an atom is observable in open cavities and waveguides, using a sequence of evolution-interrupting pulses on a nanosecond scale.

    While the diagonalization of a quadratic bosonic form can always be done using a Bogolyubov transformation, the practical implementation for systems with a large number of different bosons is a tedious analytical task. Here we use the coupled cluster method to exactly diagonalise such complicated quadratic forms. This yields to a straightforward algorithm which can easily be implemented using computer algebra even for a large number of different bosons. We apply this method on a Heisenberg system with two interpenetrating square lattice antiferromagnets, which is a model for the quasi-2D antiferromagnet Ba$\text{}_{2}$Cu$\text{}_{3}$O$\text{}_{4}$Cl$\text{}_{2}$. Using a four-magnon spin wave approximation we get a complicated Hamiltonian with four different bosons, which is treated with coupled cluster method. Results are presented for magnetic ground state correlations.

    A Schottky-barrier carbon nanotube field-effect transistor with ferromagnetic contacts was modelled. The theoretical method combines a tight-binding model and the non-equilibrium Green function technique. Tunnel magnetoresistance as well as current noise of the carbon nanotube field-effect transistor are the main issues addressed in this study. It is shown that the former may exceed 50%, whereas the latter is characterized by the Poissonian Fano factor (F) within the sub-threshold region, and the sub-Poissonian F≈0.5 for elevated gate voltages. Remarkably, reorientation of relative magnetization alignments of the contacts may lead to noticeable changes in the current noise.

We indeed show experimentally that the non-orthogonality of these two eigenstates results in an increase in the laser quantum noise. We also give a physical explanation of this vectorial excess noise factor. The second example illustrates the capabilities of two-frequency lasers in terms of applications. In the domain of RF frequency generation by optical means, we show how a pulsed two-frequency source can be built for lidar-radar applications and pulsed RF frequency generation.

    Electrochemical double-layer capacitor (also called supercapacitor) is an electrochemical energy storage device with a high power density, which could be used in application such as pulse power devices or electric vehicles. The paper describes construction of an electrochemical double-layer capacitor that consists of two electrodes immersed in an electrolyte with a separator between them. One electrode consists of a current collector in contact with the active material, while the other one is a counter electrode. Commercially available activated carbon (AC) material, composite $RuO_{2}$ + AC and natural copper sulfides are used as the active electrode material. Characterization has been performed by an electrochemical system fully developed at Technical Faculty in Bor. The system is based on a PC P4, a commercially available ADDA converter and an external interface for analog signal processing. The software platform is LabVIEW 8.2 package and application software is adapted to investigations of the systems containing high capacitances.

    We investigated the influence of zero-point fluctuations (vacuum fluctuations, optical quantum noise) to the optical response of electromagnetic metamaterials containing dielectrics with third-order Kerr-like nonlinearity. We determined the zero-point noise and calculated it for different analytes, including those used in forensic analysis and organic pollutants. The zero-point noise level is highest for shortest-wavelength plasmons and decreases towards long-range plasmons. It may be tailored through a convenient design of the metamaterial structure. Since noise spectral power is proportional to the nonlinearity of the analyte species present, we considered the possibility to use zero-point noise as an auxiliary tool for identification of targeted nonlinear samples. We believe that our investigation could be of importance in homeland defence, forensics, biomedicine, etc.

The article discusses the lowest levels of sounds recorded at night in the soundscape of the Białowieża Forest. Due to low levels of the examined sounds and the technical problems that occurred while the sounds were being measured and registered, the acoustic examination of the measurement set-up in an anechoic chamber has also been presented. The research is aimed at defining precisely the concept of quietness prevailing in the nature in the subjective aspect by determining both the range of levels and the characteristics of preferred sounds.

    Opis:
    Bulk monocrystals of $Pb_{1-x}Cd_{x}Te$, with the Cd content x up to 0.11, were grown by physical vapour transport method. The structural, electrical and optical properties of these ternary crystals were studied experimentally and theoretically. All investigated samples exhibit rock-salt structure and high crystal quality, which was confirmed by X-ray rocking curve width parameter of about 100 arcsec. The decrease of the lattice parameter with increasing Cd content x was found experimentally, in agreement with ab initio calculations. The band structures of $Pb_{1-x}Cd_{x}Te$ mixed crystals for x values up to 0.2 were calculated using tight binding approach. The calculated band gap in the L-point increases with the Cd content in qualitative agreement with photoluminescence measurements in the infrared. For all studied $Pb_{1-x}Cd_{x}Te$ samples, the Hall effect and electrical conductivity measurements, performed in the temperature range from 4 to 300 K, revealed p-type conductivity.
