Opis:
To establish the brine chemistry associated with the evaporites in the Pennsylvanian Paradox Basin of southeastern Utah and southwestern Colorado (USA), the composition of primary fluid inclusions was determined for sedimentary halite from two drill cores, one near the central part of the basin (Shafer Dome No. 1) and one from a more marginal location of the basin (Gibson Dome No. 1). Chemical analysis of halite fluid inclusions was done on six samples from three different evaporite cycles of the Paradox Formation; cycle 10 in the Shafer Dome core and cycles 6 and 18 from the Gibson Dome core. The inclusions that range in size from 2 to 80 microns across, were analyzed using the Petrychenko method. Large inclusions (40 to 80 microns across) that were used for the chemical analyses contain one fluid phase with a carnallite or sylvite daughter crystal. Also reported in this study are fluid inclusion homogenization temperatures for sylvite or carnallite from primary halite crystals in the Gibson Dome core and in Shafer Dome. The relationship between K+ and Mg2+ in chloride rich inclusions corresponds to their proportion in MgSO4-depleted marine waters concentrated to the stage of carnallite deposition. A correlative relationship was observed between K+2+4-rich to MgSO4-poor compositions that have been proposed by other workers. A transition from MgSO4-rich to MgSO4-poor seawater composition may have occurred between Pennsylvanian and Permian times. This paper presents a possible alternate explanation to those already proposed in the literature, that the Paradox Formation mineralogy resulted from an intermediate seawater composition that records the global transition from MgSO4-rich to MgSO4-poor seawater.

Opis:
The Integrated Zone Comparison Technique (IZCT) was utilized with computerized polygraph instrumentation and the Academy for Scientific Investigative Training’s Horizontal Scoring System ASIT PolySuite algorithm, as part of a blind study in the detection of deception. This paper represents a synergy analysis of combining fMRI only deception data with each of the three individual physiological parameters that are used in polygraph. They include the electro-dermal response (EDR), pneumo, and cardio measurements. In addition, we compared the detection accuracy analysis using each single parameter by itself. The fMRI score and each individual polygraph parameter score on individual subjects were averaged to establish an overall score.

Opis:
Newly collected material reveals that the Silurian myodocope ostracods from the Holy Cross Mountains, Poland comprise ten species (one new to science) belonging to four families: Bolbozoidae, Entomozoidae, Rhomboentomozoidae, and Cypridinidae. Biostratigraphic control using graptolites indicates that all three Polish outcrops investigated are of about the same chronostratigraphical level: middle Gorstian, lower Ludlow. The new occurrences in Poland extend the known distribution of several species and reinforce data that show many Silurian myodocope species with wide dispersal. Our new observations on the Holy Cross Mountains material confirm that the occurrences of Silurian myodocopes are mostly associated with pelagic animals and with rocks ranging from mudstone, siltstone or shale deposited in open- or deep-shelf marine settings. The cosmopolitan distribution of these ostracods, coupled with their facies and faunal associations, supports the notion of an ostracod (myodocope) ecological shift from benthic to planktonic habitats during the late Wenlock and Ludlow.

Opis:
The neutralization theory of Sykes and Matza (1957) posits that delinquent individuals attempt to continually reintegrate with society by mentally asserting that their deviant behavior is actually normative, via an excuse. Sykes and Matza gave five excuses, or techniques of neutralization: denial of responsibility, denial of injury, denial of the victim, condemnation of condemners, and appeal to higher loyalties. Sykes and Matza were primarily concerned with the general concept of neutralization, rather than trying to understand the specific utilities of the different technique categories they labeled. The goal of this work is to determine which techniques may be most common, and under what circumstances (what crimes or deviant behaviors) neutralizations may be most effective. Using a factorial vignette survey design with a multinational sample of college students from Poland and the United States, we find neutralization utility varies by technique and circumstance, and the denial of responsibility technique is especially potent.
Teoria neutralizacji Greshama Sykes’a i Davida Matzy (1957, s. 699) zakłada, że przestępcy nieustannie próbują reintegrować się ze społeczeństwem poprzez psychologiczne uznanie swoich dewiacyjnych zachowań za właściwie normatywne, przy użyciu ,,wymówek” nazwanych technikami neutralizacji. Sykes i Matza wyróżnili pięć takich technik: kwestionowanie odpowiedzialności, kwestionowanie szkody, kwestionowanie ofiary, potępianie potępiających oraz odwoływanie się do wyższych racji. Autorzy początkowo skupiali się na szerszym rozumieniu zjawiska neutralizacji niż na zgłębianiu funkcjonowania poszczególnych technik, które wyróżnili. Celem niniejszego artykułu jest ustalenie, które techniki neutralizacji są najczęściej używane oraz w jakich okolicznościach (przy popełnieniu jakich przestępstw) neutralizacja jest najbardziej efektywna. Za pomocą planu czynnikowego sondażu diagnostycznego, który objął grupę studentów z Polski i ze Stanów Zjednoczonych ustalono, iż stosowalność neutralizacji różni się w zależności od użytej techniki i od okoliczności oraz że kwestionowanie odpowiedzialności stanowi najsilniejszą z technik.

The advent of language implementation tools such as PyPy and Truffle/Graal have reinvigorated and broadened interest in topics related to automatic compiler generation and optimization. Given this broader interest, we revisit the Futamura Projections using a novel diagram scheme. Through these diagrams we emphasize the recurring patterns in the Futamura Projections while addressing their complexity and abstract nature. We anticipate that this approach will improve the accessibility of the Futamura Projections and help foster analysis of those new tools through the lens of partial evaluation.

Opis:
Many historic structures are located in regions of significant seismic activity and are vulnerable to earthquake damage. To assess the safety of these structures, an understanding of the seismic performance of key elements such as masonry arches, vaults and domes is vital. While static stability of masonry arches can be studied analytically using the principles of limit analysis, numerical methods are needed to deal with more complex geometries and/or dynamic load cases. A promising numerical approach is the Discrete Element Method (DEM). Currently, DEM codes are rather specialised research tools, and further development and validation are needed to confirm their suitability. In this paper, the DEM code LMGC90 is used to analyse the responses of arches subjected to dynamic base motions, with the results compared to shaking table experiments on arches built from wooden voussoirs. It is shown that the code is able to model the sequence of hinge openings and the final collapse mechanism extremely well. However, the numerical simulations overestimate the base acceleration amplitudes required to cause collapse. This is thought to be due to the impossibility of modelling the exact experimental set-up, which is substantially affected by small imperfections in the contacts between adjacent voussoirs. The resultant error is found to be quite consistent between tests, and has been compensated by a simple calibration of the experimental models. Future work will seek improved methods of dealing with this issue, and extension of the DEM approach to arches and vaults made of concrete-like materials, with non-zero tensile strength.

Opis:
The efficiency of pollution removal from municipal sewage in two vertical flow constructed wetlands consisting of gravel filters with a surface area of 4 × 5 m, depth 60 cm, planted with reed (Phragmites) was assessed over a period of about two years. The flow of wastewater was 50 mm per day. Wastewater underwent only primary treatment before application to reed bed B, but reed bed A was supplied with wastewater after mechanical and biological treatment. Measurements were taken of sewage supply and discharge, precipitation and wastewater temperatures. The main indicator of efficiency was the elimination of suspended solids, BOD5, nitrogen and phosphorus from the wastewater during treatment. The elimination of the pollution load was 2-25g O2 per square meter per day for the BOD5 and 0-3.5 g per square meter per day for so-called "total nitrogen". Rates of pollution removal were between 2 and 4 times as high in bed B (after primary treatment) as in bed A (after biological treatment), but the loading rate of bed B was also substantially higher. The rate of BOD5 removal and the coefficient k for BOD5 were greatly dependent on temperature for reed bed B (primary treatment); less so for bed A (biological treatment). The difference between summer and winter temperatures indicates that the surface area of constructed wetland B with wastewater after mechanical treatment should be about 3 times greater during winter, to obtain the summer rate of BOD5 pollution removal in the climatic conditions of Northern Poland (54oN).

Opis:
Ordovician ostracods are described for the first time from Iran, enhancing the record of this group from the Lower Palaeozoic of the Middle East. The ostracods occur in the Shirgesht Formation, in the east central part of the country, and comprise Ogmoopsis achaemenid sp. nov., Cerninella aryana sp. nov., Ordovizona amyitisae sp. nov., cf. Aechmina? ventadorni, Vogdesella sp., and podocope taxa tentatively identified as species of Longiscula, Pullvillites, and Rectella. These taxa were hitherto unknown from this region. The ostracod−bearing interval is associated with trilobites (Neseuretinus) and brachiopods (Nicolella) that suggest a late Middle Ordovician age. Although the ostracod fauna is small, it demonstrates biogeographical links at genus−level, and possibly at species−level, with the fauna of the late Middle Ordovician Travesout Formation of western France, which also lay in a peri−Gondwanan palaeogeographical setting. It also suggests the potential use of some ostracods as stratigraphical tools for correlating Ordovician rock successions between Europe and the Middle East.

Opis:
Tetrazene (1-amino-1(1H-tetrazol-5-yl)-azo-guanidine hydrate) is widely used in ordnance systems as a sensitizer of primer mixes for use in both percussion and stab applications. It has low thermal and hydrolytic stability compared with other components of primer mixes and there currently exists the need for a replacement with enhanced stability characteristics. MTX-1 (1-[(2E)- 3-(1H-tetrazol-5-yl)triaz-2-en-1-ylidene]methanediamine) meets these criteria and shows great promise as a tetrazene replacement. Preliminary testing of this material has confirmed that MTX-1 has safety and performance properties which are similar to tetrazene and has chemical characteristics, including thermal and hydrolytic stability, which exceed those of tetrazene. MTX-1 has been successfully evaluated against tetrazene in a variety of chemical/output tests, including comparative testing in the PVU-12 primer.

Opis:
Isotopic and palaeomagnetic studies were carried out in the central part of King George Island. Selected mafic to intermediate igneous rocks were sampled for this purpose. Single-grain U-Pb dating of zircons from basalts to dacites was controlled by a whole rock 40Ar-39Ar data and the magnetostratigraphy. Five magmatic activity phases were distinguished in the SE coast of King George Island. The oldest, late Cretaceous (Campanian) phase represented by basalts of the Uchatka Point Formation are followed by the early to middle Eocene (~53–43 Ma) phase documented by the lava flows whose ages decrease from SW to NE. Next younger magmatic activity phases were recorded by the lava flows or vertical intrusions emplaced in the late Eocene (~37–35 Ma), late Oligocene (~~28-25 Ma) and late Pliocene to Holocene. The early to middle Eocene magmatic activity phase was the most extensive, producing the largest volume of magma in the study area. The new age determinations allow a more precise and credible stratigraphic correlation of the interbeds of sedimentary rocks observed in some places within the magmatic succession. The glacial provenance of the Herv' Cove diamictite is not obvious. It might represent a mountain river environment. Intense volcanic activity could be additional factor modelling the climate conditions of Antarctica in Paleogene

Given the history of the past, black South African students from different settings face unique academic and emotional climate. Using the Differential Emotions Scale (DES) which focuses on ten discrete emotions, and building upon Boyle’s (1984) seminal work, this study reports a repeated-measure multiple discriminant function analysis for individual items across raters. The findings further indicate that majority of the DES items are sensitive indicators of the different innate and universal facial expressions. However, the construct requires revision so that it offers the examiner maximum flexibility in assessment at diverse levels, in terms of more extensive norming and programmatic replication. In brief, the DES potentially has much to offer provided that it is adequately developed for use in non-Western nations or contexts.

Opis:
The studies of transport and optical properties of GaAs implanted with high arsenic doses were performed. As-implanted samples showed hopping conductivity and the exponential absorption tail in the near-IR region. Both effects were probably caused by the amorphization of implanted layer. Using EPR measurements it was found that arsenic antisite defect with high local strain field was created during implantation. Annealing of implanted layers at 600°C led to substantial removal of amorphization, decrease in absorption coefficient and hopping conductivity leading to resistive samples. The possible model of such behaviour may be similar to the one of suggested for low temperature GaAs layers.
