Opis:
The horse chestnut leaf miner, Cameraria ohridella Deschka & Dimic (Lepidoptera: Gracillariidae), is a new invasive pest that has spread all over the Europe over the last 25 years. This paper presents research aimed to: 1) compare the effectiveness of sticky pheromone traps of various types (sizes and colors), 2) determine the effect of a trap location on moth catches. Studies were conducted in Warsaw and Falenty near Warsaw. No trap color preference by male moths was found in tests of white, blue and green barrier traps. Barrier traps had the largest sticky area (32 dm2) in comparison to PL-2 (5.625 dm2) and delta PL-1 (3.4 dm2) traps, thus they caught the highest total number of males, however PL-2 traps were the most effective (268-381 moths/dm2). The results of the studies suggest that to make traps with the C. ohridella pheromone be more effective they should: a) be located on a stem below a tree crown or in its lower part for the first C. ohridella generation, and in crowns for the second and later insect generations, b) be placed in some distance from a tree stem, if located in crowns.

Opis:
This paper shows possibility of utilization ether derivatives of (8E,10Z)-tetradeca-8,10-dienal [2-((7E,9Z)-trideca-7,9-dienyl)-1,3-dioxan (2) and 2-((7E,9Z)-trideca-7,9-dienyl)-4-hydroxy-6-heptyl-5-hexyl-1,3-dioxan (3)] as potential lures for monitoring of horse-chestnut leafminer population. The both propheromones were synthesized at the Institute of Industrial Organic Chemistry (IPO) and then tested in 2006/07 on field trials at several different sites on terrain of Mazovian province. Within the scope of these investigations, acetal 2 was checked at different doses (10, 100, 500 μg) by the pheromone trapping technique, and aldoxane 3 was used both in pheromone trapping (at the dose 50 μg) and mating disruption technique. The good attractiveness properties were obtained for both tested compounds. However, the dose of 2-((7E,9Z)-trideca-7,9-dienyl)-1,3-dioxan had to be a 10 times higher than dose of aldoxane for the same good activity.

Project Riese

Opis:
Project Riese (German for giant) in the Owl Mountains (Góry Sowie), located in Lower Silesia, was the largest mining and building project of Nazi Germany. The construction work was done by forced laborers, POWs, and prisoners of concentration camp Gross-Rosen. Many of them lost their lives. The whole project was kept in secret, even the beginning of the construction work is unclear. The purpose of Riese remains uncertain because of lack of documentation, it is still rather a hypothesis than a fact. The only verified information is that the project was abandoned at the initial stage due to the approach of the Red Army. Before that, Nazis put a lot of effort to hide all information about Riese. Today, we can see how successful these efforts were. Nowadays, six underground structures were discovered in Walim and Głuszyca area: Włodarz (3000 m of tunnels), Osówka (1700 m of tunnels), Sokolec (or Gontów – 800 m of tunnels), Soboń (740 m of tunnels), Rzeczka (560 m of tunnels), Jugowice (500 m of tunnels) and about 600 m of tunnels under Książ Castle in Wałbrzych (Aniszewski 2002, Graba 2012). It has been found that many of the tunnels in some structures have a dead end, and there is a theory this might prove that all complexes were supposed to be combined. It is believed that many kilometers of the underground tunnels are still to be discovered (Cera 1998). The whole area is one of the most popular destinations for treasure hunters and scientists. Nowadays treasure hunters are using not only maps and metal detectors, but also GPRs. Scientists are interested in Riese because of many underground tunnels in various sizes and depth, as well as huge amount of steel which was used to reinforce adits. All these details allow scientists to perform many different types of research. Geophysicists are testing the equipment and methodology in the area of gravimetric, magnetic and GPR measurements. All geophysical measurements need to be put into the coordinate system, local or global. Moreover, to eliminate gravity or magnetic effect of the excavations and steel reinforcements their shape must be known (Porzucek 2013). To meet the needs of scientists, researchers, tourists and museum authorities, authors of this report, with the help of students, performed a full inventory of Osówka complex. It was performed in 2015 and covered all underground and ground objects. 1700 m of underground tunnels in the main part of the complex (Museum of Underground City Osówka) were scanned, together with 130 m of Sztolnia Wodna (from Polish water adit) and two ground objects: Siłownia and Kasyno. These two objects are supposed to be nuclear energy plants and Hitler’s headquarters or command headquarters (Cera 1998). During measurements, laser scanner (Faro, Focus 3D), tachymeter (Topcon, OS103) and GPS receivers (Topcon, HiperPro) for georeferencing were used. The main scientific importance of the study is a unique data set that was collected during this research. Afterwords, geometrical relations between objects of Osówka complex were analyzed. The previously supposed course of the Sztolnia Wodna and its destination was revised. Moreover, the possible lift shaft connecting Siłownia and underground part of Osówka was confirmed. The report presents location of objects in relations to each other which was not previously verified in research or verified in the other ways. Although, it is possible to do geophysics measurement on unexplored field, data from researches provides possibility of introducing excavations height and size amendments. Another inventory result is a virtual museum, available from 1st April for everybody on Museum of Underground City Osówka website (www. osowka.pl). The user can virtually explore the whole complex, including places where visitors are not allowed. During measurements, flooded adits have also been inventoried: the ones in the museum and in Sztolnia Wodna (entrance collapsed in November 2015 and the whole adit is in danger of collapsing). Inventory also included Siłownia (firstly, water has been pumped out to allow measurements in the staircase and alleged lift shaft). Another inaccessible place available during the virtual tour is shaft connecting the forest near Kasyno to the undergrounds. The virtual tour allows also measuring selected surface or distance between chosen points and checking coordinates or height in a particular spot. The user can generate a link to a screen which interests him and upload it to any website. It must be said that even sharing this amount of data doesn’t equate to possibility of conducting research and measurements in appointed spots. Project Riese is located on the land belonging to the local government, individuals and National Forests (the majority of it). Before taking any actions, area manager must give his permission. It is strictly enforced since the whole “golden train” story in July 2015.

In the paper discusses the influence of grounding or shorting of the screen on the magnetic field of screened phase conductor. This phenomenon has been described with the formulas relevant to the relative values of the field and the parameters allowing the frequency, conductivity, and the cross-section dimensions of screen. Into account was taken skin, internal and external proximity effects. Components of this field were expressed through modified Bessel’s functions as a function r and & of cylindrical coordinates. As a consequence this the magnetic field is a rotating elliptical field.

New results concerning paramagnetic defects in SrLaAlO$\text{}_{4}$ and SrLaGaO$\text{}_{4}$ high-T$\text{}_{c}$ substrates connected with unavoidable impurity Fe$\text{}^{3+}$ are reported. The identification was checked by measuring the spectra in SrLaAlO$\text{}_{4}$ crystals intentionally doped with 0.5 at.% Fe. Angular dependences of three lines were distinguished at X-band frequency in the temperature range from 4 K to 300 K. We attribute these lines to the transitions inside the doublets ±1/2, and "forbidden" doublets ±3/2, ±5/2, respectively. By diagonalization of spin-Hamiltonian, parameters |D| > 1.2 cm$\text{}^{-1}$, |E| ≈ 0.1 cm$\text{}^{-1}$ and g$\text{}_{x}$=g$\text{}_{y}$=g$\text{}_{z}$= 1.987(13) for SrLaAlO$\text{}_{4}$ and SrLaGaO$\text{}_{4}$ were calculated and within the margin of error they were of the same value.

The effect of iron and silicon addition on the structure and properties of aluminium wire rod obtained in the laboratory horizontal direct chill casting process has been analysed. In addition, the impact of laboratory wire drawing process has been examined. The addition of iron and velocity of casting increase the strength of aluminium wire rod in as-cast condition while the electrical conductivity drop acceptable. Moreover, the laboratory wire drawing process causes work-hardening wires and increase drawing tension as a result of fragmentation of structure and growth of grain boundaries. It has been shown that iron is beneficial for mechanical and technological properties of aluminium.

Opis:
Single electron devices (SEDs) are candidates to become a keystone of future electronics. They are very attractive due to low power consumption, small size or high operating speed. It is even possible to assure compatibility with present CMOS technology when natural potential fluctuations introduced by dopant atoms are used to create quantum dots (QD). However, the main problem of this approach is due to the randomness of dopant distribution which is characteristic for conventional doping techniques. This leads to scattered characteristics of the devices, which precludes from using them in the circuits. In these work we approach the problem of correlating the distribution of QD's with the device characteristics. For that, we investigate with a Kelvin probe force microscope (KFM) the surface potential of Si nanodevice channel in order to understand the potential landscape. Results reveal the features ascribable to individual dopants. These findings are supported also by simulation results.

Opis:
Future RF Control systems will require simultaneous data acquisition of up to 100 fast ADC channels at sampling rates of around 100 MHz and real time signal processing within a few hundred nanoseconds. At the same time the standardization of Low-Level RF systems are common objectives for all laboratories for cost reduction, performance optimization and machine reliability. Also desirable are modularity and scalability of the design as well as compatibility with accelerator instrumentation needs including the control system. All these requirements can be fulfilled with the new telecommunication standard ATCA when adopted to the domain of instrumentation. We describe the architecture and design of an ATCA based LLRF system for the European XFEL. Initial results of the demonstration of such a system at the FLASH user facility will be presented. Presented are the results of operating essential components of a prototype during the machine studies in January and March 2009.

The paper concerns the subject of the optimal center frequency selection for the amplitude demodulation, which is a principal tool for detection of bearing faults. In the first part, existing methods along with their advantages and drawbacks are discussed. A special attention is paid to methods implementing kurtosis-based estimators. In following sections, the authors demonstrate a novel method based on the so called "max-med" estimator. The method is validated on a real signal containing a bearing fault signatures.
Tematyka artykułu dotyczy optymalnego wyboru częstotliwości nośnej w procesie demodulacji amplitudowej, która jest podstawowym narzędziem detekcji uszkodzeń łożysk. Pierwsza część pracy przedstawia obecnie używane metody wskazując ich zalety oraz wady, ze szczególnym uwzględnieniem metod bazujących na kurtozie. W kolejnych częściach pracy autorzy ilustrują nową metodę z wykorzystaniem operatora "max-med" (od ang. maximum-median). Działanie zaprezentowanej metody jest weryfikowane na sygnale rzeczywistym zawierającym komponenty generowane przez uszkodzone łożysko.
