Opis:
In this paper we present analysis of how contact data is managed by Windows on mobile phones and our approach in making it more private. Aim of this work was to design and develop application that can store contacts locally in memory of device with installed Windows Phone 8.1 operating system. That application can be used to create, edit, and remove contacts without usage of Microsoft cloud services. Developed application also allows to send text messages, e-mails, and call to saved telephone number.

Opis:
The rehydration from the gaseous phase of the developing native or EDTA-washed from unbound and loosely bound paramagnetic ions wheat thylakoid membrane lyophilizate was investigated using hydration kinetics, sorption isotherm, and high power proton relaxometry. Hydration time courses are single exponential for all target humidities. The sorption isotherm is well fitted by the Dent model, with the mass of water saturating primary binding sites equal toΔ M/m$\text{}_{ }$0=0.024 and 0.017 for native and EDTA-washed membranes, respectively. Proton free induction decays distinguish: (i) a Gaussian component, S$\text{}_{0}$, coming from protons of solid matrix of lyophilizate; (ii) a Gaussian component, S$\text{}_{1}$, from water bound to the primary water binding sites in proximity of water accessible paramagnetic ions; (iii) an exponentially decaying contribution, $L$\text{}_{1}$$, from water tightly bound to lyophilizate surface; and (iv) exponentially decaying loosely bound water pool, L$\text{}_{2}$. Sorption isotherm fitted to NMR data shows a significant contribution of water "sealed" in membrane structures (Δ M$\text{}_{s}$/m$\text{}_{0}$=0.052 for native and 0.061 for EDTA-washed developing membranes, respectively).

Opis:
Two Chlamydomonas reinhardtii CW15 populations modified by an excess of copper in growth medium were obtained: a “Cu” population that was continuously grown under the selection pressure of 5 μM Cu²⁺ (for at least 48 weeks) and the “Re” population, where a relatively short (9 week) exposure to elevated copper, necessary for acquiring tolerance, was followed by a prolonged period (at least 39 weeks) of cultivation at a normal (0.25 μM) copper concentration. Cells of the Cu population were able to multiply at a Cu²⁺ concentration 16 times higher than that of the control population at a normal light intensity and at a Cu²⁺ concentration 64 times higher when cultivated in dim light. The potential quantum yield of photosystem II (FV/FM ratio) under copper stress was also significantly higher for the Cu population than for Re and control populations. The Re population showed only residual tolerance towards the elevated concentration of copper, which is revealed by an FV/FM ratio slightly higher than in the control population under Cu²⁺ stress in dim light or in darkness. We postulate that in the Chlamydomonas populations studied in this paper, at least two mechanisms of copper tolerance operate. The first mechanism is maintained during cultivation at a standard copper concentration and seems to be connected with photosynthetic apparatus. This mechanism, however, has only low adaptive value under excess of copper. The other mechanism, with a much higher adaptive value, is probably connected with Cu²⁺ homeostasis at the cellular level, but is lost during cultivation at a normal copper concentration.

Opis:
Mild rehydration from the gaseous phase of the developing and mature lyophilized wheat photosynthetic membranes was investigated using hydration kinetics, adsorption isotherm and high power proton relaxometry. Hydration time courses are single exponential for all target air humidities; the hydration time $t^h$ equals to (11.9±3.6) h for the mature membranes, and (17.0±3.2) h for the developing membranes. The sorption isotherm is sigmoidal in form and well fitted using the Dent model; the mass of water saturating primary binding sites equals Δ M/$m_0$= 0.033±0.013 and 0.025±0.007 for the mature and for the developing membranes, respectively, where $m_0$ is the dry mass of the sample, and Δ M is mass of water taken up. Proton free induction decays distinguish: (i) an immobilized proton (Gaussian) component, $S_0$, originating from protons of solid matrix of lyophilizate; (ii) a Gaussian component, $S_1$, from water bound to the primary water binding sites and localized in proximity of paramagnetic ions; (iii) an exponentially decaying contribution, $L_1$, from water tightly bound to lyophilizate surface; and (iv) exponentially decaying loosely bound water pool, $L_2$. A significant contribution of water "sealed" in the structure of lyophilized membrane (from the fraction $S_1$ and $L_1$) is detected. The mass of "sealed" water fraction is Δ $M_{S}//m_0$ = 0.047±0.023 and 0.072±0.021 for the mature and for the developing membranes, respectively.

Opis:
Between neighbouring bilayers of lyophilized dipalmitoylphosphatidylcholine (DPPC) multilamellar vesicles the total number of water molecules equals 9 H₂O molecules/1 DPPC molecule. One of these molecules is very tightly bound to the lipid molecule, seven are in immobilized (tightly bound) water fraction whereas the last one belongs to mobile water fraction. The rehydration from the gaseous phase of the DPPC model membranes was investigated using hydration kinetics, sorption isotherm, and high power proton relaxometry. The obtained data for DPPC were compared with these obtained for wheat photosynthetic membranes. Rehydrated photosynthetic membranes differ from DPPC model membranes in hydration kinetics. The average hydration time has a similar value: (22.0 ± 2.8) h (photosynthetic membrane) and (19.8 ± 1.6) h (DPPC), however hydration kinetics was described by one-exponential function for photosynthetic membrane, while for model membrane it shows fine double exponential form. The sigmoidal form of sorption isotherm is better fitted using Dent model than by the Brunauer-Emmett-Teller formula. The Brunauer-Emmett-Teller/Dent deviation parameter b =0.93 either for photosynthetic or for model membranes. The mass of water saturating primary water binding sites equals ΔM/m₀= 0.017 (wheat photosynthetic membranes) and 0.027 (DPPC). The detected by NMR-isotherm study mass of water "sealed" in model membrane structures was about ΔMₛ/m₀=0.182 (about 7-8 H₂O molecules/1 DPPC molecule), and ΔMₛ/m₀= 0.066 for photosynthetic membrane.

Opis:
Quasicrystals are aperiodic structures with no periodicity both in direct and reciprocal space. The diffraction pattern of quasicrystals consists however of the periodic series of peaks in the scattering vector space. The intensities of the peaks of all series reduced in a proper way build up the so-called envelope function common for the whole pattern. The Fourier transformed envelope gives the average unit cell which is the statistical distribution of atomic positions in physical space. The distributions lifted to high dimensions correspond to atomic surfaces - the basic concept of structural quasicrystals modeling within higher-dimensional approach.
