Glaciomorphological features of the North and Middle Lithuania Lowlands are described and interpreted. The ridged relief of the morainic plain in the NW part (Akmenė district, North Lithuania) is characterized by mega-scale glacial lineation (MSGL) forms, testifying to the active movement of the glacier; they do not correlate with the sub-Quaternary palaeosurface. The relief structure of the Nevėžis Moraine Plain located farther south includes areas of obscure MSGL that were affected by glaciolacustrine accumulation and abrasion, glaciofluvial accumulation and erosion, as well as intensive land drainage (amelioration) in the 20th century. Typical MSGL forms in the Mūša-Nemunėlis Moraine Plain and relicts of MSGL forms in the Nevėžis Moraine Plain, as well as patterns of orientation and inclination of macroclast long axes due to mixing of the moraine material (till), reflect the dynamics of the sliding glacier. These features show that the moraine plains of Middle and North Lithuania were formed by an actively moving glacier, which left an identifiable till layer when geological and hydrological conditions allowed.

The use of wireless technology in the field of instrumentation is rapidly expanding due to many reasons such as lower installation and commissioning cost than those incurred by wired technologies and a higher level of security provided by authenticated encrypted data transaction, in addition to a decreased level of system complicity, manifested in eliminating or limiting the need for cabling or its accessories. This article will discuss a proposed technique to perform authenticated wireless WiFi data transmission from multiple sensors to the control station depending on a laboratory stand for the purpose of analysing the principle of coexistence between wireless technologies dedicated to industrial automation, such as wireless HART, and general purpose technologies, such as WiFi and Bluetooth Low Energy BLE.

This research focuses on the practical and low-cost implementation of a fuzzy logic controller (FLC) for controlling the output voltage of a DC-DC boost converter. It is carried out using an ATmega2560-based Microcontroller of the Arduino Mega board under Matlab/Simulink environment. The developed FLC controller aims at driving the output voltage to follow the desired reference voltage signal whatever load or input voltage changes. The obtained results demonstrate the excellent performance of the proposed prototype in terms of dependability and precision in following the desired reference voltage. A comparative study with the PI conventional baseline controller shows that the developed FLC offers rapid dynamic response and better performance.

The most powerful now in the world, American X-ray laser LCLS (Linac Coherent Light Source), has been working as a research and user facility since 2009. It is further developed to LCLS II machine at the Stanford National Accelerator Laboratory SLAC in Menlo Park CA. In a certain sense, LCLS II is a response to the EXFEL machine and a logical extension of LCLS. All these machines are light sources of the fifth generation. EXFEL is expected to open user facility in 2016, at a cost of over 1 mld Euro. LCLS II, which design started in 2010, will be operational in 2017. The lasers LCLS, LCLS II and EXFEL use SASE and SEED methods to generate light and are powered by electron linacs, LCLS by a warm one, and EXFEL by a cold one. The linacs have energies approaching 20 GeV, and are around 2 - 3 km in length. EXFEL linac uses SRF TESLA microwave cavity technology at 1,3 GHz. A prototype of EXFEL was FLASH laser. SLAC Laboratory uses effectively over 50 years experience in research, building and exploitation of linear electron accelerators. In 2009, a part of the largest 3 km SLAC linac was used to build the LCLS machine. For the LCLS II machine a new infrastructure is build for two new laser beams and a number of experimental stations. A number of experts and young researchers from Poland participate in the design, construction and research of the biggest world linear and elliptical accelerators and FEL lasers like LCLS (Stanford), EXFEL (DESY) and CEBAF (JLab), and a few more. The paper concentrates on the development state-of-the-art of large laser infrastructure and its global and local impact, in the competitive world of R&D. LCLS infrastructure implications in Poland are considered.

The objective of the research under the paper topic is an analytical, unified formulation of a new standardized view of general solution of hydrodynamic problem using algorithm to determine changes of the components of the velocity vector, the distributions of hydrodynamic pressure, load carrying capacity, of slide bearings with cooperating curvilinear, orthogonal surfaces that are lubricated with a various non-Newtonian lubricants. In this paper for non- Newtonian lubricants are questioning the hitherto prevailing assumptions using in hydrodynamic theory of lubrication such as constant value of lubricant viscosity and pressure in the thickness of lubricating gap i.e. in gap height direction. Finally, the non-homogeneous partial differential equation generated with variable coefficients that is the result of the various boundary conditions being imposed that are different for each problem solved is an equation that determines the distributions of hydrodynamic pressure values. This equation is to be written in the form of a unified non-homogenous partial recurrence equation with variable coefficients. The Authors foresee that a mega-algorithm will be developed for the solution of this equation in a numerical form. This equation in particular cases is an equivalent of modified Reynolds equations in the research that has been conducted so far concerning the hydrodynamic theory of lubrication.

Stratigraphy and sedimentology of the Niger Delta

During the Cenozoic, until the Middle Miocene, the Niger Delta grew through pulses of sedimentation over an oceanward-dipping continental basement into the Gulf of Guinea; thereafter progradation took place over a landward-dipping oceanic basement. A 12,000 m thick succession of overall regressive, of flapping sediments resulted that is composed of three diachronous siliciclastic units: the deep-marine pro-delta Akata Group, the shallow-marine delta-front Agbada Group and the continental, delta-top Benin Group. Regionally, sediment dispersal was controlled by marine transgressive/regressive cycles related to eustatic sea-level changes with varying duration. Differential subsidence locally influenced sediment accumulation. Collectively, these controls resulted in eleven chronostratigraphically confined delta-wide megasequences with considerable internal lithological variation. The various sea-level cycles were in or out of phase with each other and with local subsidence, and interfered with each other and thus influenced the depositional processes. At the high inflection points of the long-term eustatic sea-level curve, floodings took place that resulted in delta-wide shale markers. At the low inflection points, erosional channels were formed that are often associated, downdip, with turbidites in low-stand sediments (LSTs). The megasequences contain regional transgressive claystone units (TST) followed by a range of heterogeneous fine-to-coarse progradational or aggradational siliciclastic (para)sequence sets formed during sea-level high-stand (HST). An updated biostratigraphic scheme for the Niger Delta is presented. It also updates a sedimentation model that takes into consideration local and delta-wide effects of sea-level cyclicity and delta tectonics. Megasequences were formed over time intervals of ~5 Ma within individual accurate megastructures that laterally linked into depobelts. The megasequences form the time-stratigraphic frame of the delta and are the backbone for the new delta-wide lithostratigraphy proposed here. Such a new lithostratigraphy is badly needed, in particular because of the vigorous new activity in the offshore part of the Niger Delta (not covered in this contribution). There, as well as in the onshore part of the delta, the traditional lithostratigraphic subdivision of the Cenozoic Niger Delta section into three formations is insufficient for optimum stratigraphic application; moreover, the various informal subdivisions that have been proposed over time are inconsistent.

Gasoline engine development has to respond to requirements for fuel efficient and clean combustion. In meeting such targets, the automotive industry has responded with the introduction and continuous improvement of turbocharged gasoline direct injection (TC GDI) combustion systems. Specific challenges to such engines include irregular ignition and combustion events which are rarely met in conventional engines. The paper describes ignition phenomena and mechanisms relevant for the development of such TC GDI engines. Focus then is given to combustion measurement techniques applied for the identification of these spontaneous and riskfull combustion events. As analysis of such ignition events must be done in real, high load multicylinder engine operation, suitable sensors together with measurement and analysis procedures are described. The paper concludes with analysis examples derived from various engine testing situations.

Rozwój silników benzynowych musi podążać za zmieniającymi się wymaganiami dotyczącymi efektywności i czystości spalania. Aby sprostać tym wymaganiom przemysł samochodowy wprowadza ciągłe zmiany i ulepszenia procesów spalania w silnikach benzynowych z wtryskiem bezpośrednim i z turbodoładowaniem. Szczególnym wyzwaniem w konstruowaniu tych silników są zjawiska nieregularnego zapłonu i spalania stukowego rzadko występujące w silnikach konwencjonalnych. Ten artykuł opisuje zjawiska towarzyszące zapłonowi oraz inne mechanizmy istotne z punktu widzenia rozwoju tych silników. Dużo uwagi poświecono technikom pomiaru spalania stosowanym do opisu przypadków niebezpiecznych ze względu na ryzyko niekontrolowanego spalania stukowego. Analiza takich przypadków nieprawidłowego zapłonu musi być dokonana podczas rzeczywistej pracy wielocylindrowego silnika przy dużych obciążeniach. W artykule opisano odpowiednie do tego celu czujniki wraz z metodami pomiaru i analizy danych. W części końcowej artykułu przedstawiono analizę przykładów zaczerpniętych z różnych badań silnikowych.

The study, carried out in 2003 and 2006 at the Lubiatowo Coastal Research Station (Poland), located on the non-tidal southern Baltic coast (tidal range < 0.06 m), focused on larger rhythmic forms (mega-cusps) with wavelengths in the interval 500 m > Lc > 20 m. Statistical analyses of detailed shoreline configurations were performed mostly with the Discrete Wavelet Transform method (DWT). The beach is composed of fine sand with grain diameter D50 ? 0.22 mm, which produces 4 longshore sandbars and a gently sloping seabed with ? = 0.015. The analysis confirms the key role of bars in hydro- and morphodynamic surf zone processes. The hypothesis was therefore set up that, in a surf zone with multiple bars, the bars and mega-scale shoreline rhythmic forms form one integrated physical system; experimental evidence to substantiate this hypothesis was also sought. In such a system not only do self-regulation processes include swash zone phenomena, they also incorporate processes in offshore surf zone locations. The longshore dimensions of large cusps are thus related to the distances between periodically active large bed forms (bars). The spatial dimension of bar system activity (number of active bars) depends, at a given time scale, on the associated hydrodynamic conditions. It was assumed that such a time scale could include either the development and duration of a storm, or a period of stable, yet distinct waves, capable of remodelling the beach configuration. The indentation to wavelength ratio of mega-cusps for the studied non-tidal dissipative environment may be one order of magnitude greater than for mesotidal, reflective beaches.

German employers’ liability insurance associations or Berufsgenossenschaften (BGs)—institutions for statutory accident insurance—maintain a measurement system for hazardous substances, the so-called BGMG. The aim of the BGMG is to determine and document valid results of measurements of exposure primarily for prevention purposes. The data are collected systematically, in parallel to the sampling in a company. Parameters which are supposed to have a visible effect on exposure levels are documented. The MEGA database (documentation of measurement data relating to workplace exposure to hazardous substances) holds 1,629 million measurement values, which have been compiled in since 1972. The database offers a host of selection possibilities for assessments depending on the evaluation strategy.
