Published: January 2014

Streszczenie
W niniejszym artykule przedstawiono wyniki badań próbek skał węglanowych pobranych z utworów triasowych, w obszarze Śląska Opolskiego. Przedmiotem badań była identyfikacja huntytu - fazy węglanowej, o podwyższonej, w porównaniu z kalcytem magnezowym i dolomitem, zawartości magnezu. Huntyt powstaje zwykle wskutek procesów hydrotermalnych, wietrzenia dolomitu lub w wyniku przeobrażenia, w warunkach wysokich temperatur, kalcytu magnezowego. W skałach osadowych występuje w utworach strefy wadycznej (aeracji). W celu stwierdzenia obecności huntytu, wybrane próbki skał poddano analizom FTIR, rentgenowskiej oraz badaniom w mikroobszarach. Minerał ten zidentyfikowano w skałach wapienia muszlowego, w wapieniach warstw gogolińskich, górażdżańskich, dziewkowickich i karchowickich. W przypadku analizy FTIR, o obecności huntytu świadczy występowanie w widmach absorpcyjnych, w próbkach 1 i 4 pasma 1555 cm-1, w próbce 3 - pasma 1562 cm-1, a w próbce 2 - pasma 1572 cm-1. W dyfra kto gra mach rentgenowskich wszystkich badanych próbek, fazę węglanową uznaną za huntyt zidentyfikowano na podstawie linii dy|frakcyjnej, o najwyższej intensywności i wartości dhkl - 2,83 A. Badania w mikroobszarach pozwoliły na zidentyfikowanie huntytu w wapieniach dziewkowickich oraz karchowickich. Oznaczone w punktach mikroobszarów badanych próbek, zawartości magnezu, wahają się od 14,01% Mg (23,23% MgO) do 16,18% Mg (26,83% MgO). Wartości te przekraczają znacznie wartość stechiometryczną, typową dla dolomitu (21,86% MgO, 13,12% Mg). Oznaczona w mikroobszarach ilość magnezu w huntycie jest jednak niższa od wartości stechiometrycznej dla tej fazy węglanowej, która wynosi 20,65% Mg (34,25% MgO). Prawdopodobnie, wskutek procesów diagenezy (de- dolomityzacja ?) mogło dojść do usunięcia części jonów magnezu z kryształów huntytu. Analizując możliwości tworzenia się huntytu, fazy węglanowej o podwyższonej zawartości magnezu, w więk- szym stopniu niż Mg-kalcyt czy dolomit, można podejrzewać, że minerał ten powstał w obszarach zbiornika germańskiego, w których procesy diagenezy zachodziły przy udziale wód strefy wadycznej.

Abstract
Given the most competitive nature of global business environment, effective engineering innovation is a critical requirement for all levels of system lifecycle development. The society and community expectations have increased beyond environmental short term impacts to global long term sustainability approach. Sustainability and engineering competence skills are extremely important due to a general shortage of engineering talent and the need for mobility of highly trained professionals [1]. Engineering sustainable complex systems is extremely important in view of the general shortage of resources and talents. Engineers implement new technologies and processes to avoid the negative environmental, societal and economic impacts. Systems thinking help engineers and designers address sustainable development issues with a global focus using leadership and excellence. This paper introduces the Systems Engineering (SE) methodology for designing complex and more sustainable business and industrial solutions, with emphasis on engineering excellence and leadership as key drivers for business sustainability.
The considerable advancements achieved in complex systems engineering indicate that the adaptation of sustainable SE to business needs can lead to highly sophisticated yet widely useable collaborative applications, which will ensure the sustainability of limited resources such as energy and clean water. The SE design approach proves critical in maintaining skills needed in future capable workforce. Two factors emerged to have the greatest impact on the competitiveness and sustainability of complex systems and these were: improving skills and performance in engineering and design, and adopting SE and human systems integration (HSI) methodology to support sustainability in systems development. Additionally, this paper provides a case study for the application of SE and HSI methodology for engineering sustainable and complex systems.

Published: January 2014

Abstract
Within classic German manufacturing structures, costs of resources exceed all other cost factors by 46% [1]. Solitary focus on energy or labor costs as sources to raise companies profit no longer seems adequate. Nowadays material costs of the manufacturing industry are about 500 billion euro per year, connected with a saving potential of 100 billion euro per year. Also the belonging for sustainably produced products is raising and becoming a factor for guaranteed purchases [2]. A small and medium-sized enterprise fitted approach, which ensures to increase the transparency of internal process structures and allows a resource driven, ecological and economical assessment, is the main subject of this article.
SUSTAINABILITY THROUGH PRODUCTION NETWORKS

Published: January 2014

Abstract
Global economic crisis has brought into question sustainability of many industrial enterprises, especially Large-sized Enterprises (LEs). However, the strength of the European economy are not Large-sized Enterprises, but Small and Medium-sized industrial Enterprises (SMEs). As an alternative to LEs there is networking of SMEs into flexible production networks. Inside production network SMEs can collaborate on new product development forming Virtual Enterprise. SMEs collaborating as one Virtual Enterprise can be seen as a sustainable Large-sized Enterprise. However, to achieve sustainability through production networks, i.e. Virtual Enterprises, it is essential to choose an optimal combination of SMEs in Virtual Enterprise formation process. Since it is a complex task that requires the use of multi-criteria decision-making methods, in this paper PROMETHEE method is used.
New data on the distribution of Bryum minii (Bryaceae, Bryophyta) in Portugal with ecological and chorological considerations
Authors: Sérgio Cecília , Garcia César Augusto , Stow Sarah 
Published: January 2014

Abstract Bryum minii Podp. ex Machado-Guim. was first described from Portugal in the nineteenth century and only recorded in Spain in 2010. It is found on acidic rocks, such as granite, near watercourses and its glossy appearance makes it relatively easy to identify in the field although it grows in small patches. New chorological data are provided for Portugal, as well as species photographs and an updated distribution map which show that it is no longer a rare species in Portugal and can therefore not be considered threatened. It is likely that more records of this moss will be found with new fieldwork in riparian communities.

Abstract
Since 2005 a breeding pair of A. pomarina has been observed near the village of Drienovec, Košice-Environs district, eastern Slovakia. Since 2009 occupied nests have been found each year with the subject pair. In the years 2009, 2010, 2011 and 2013 this pair successfully reared one young A. pomarina, but in 2012 they reared two B. buteo young during the nesting period in natural conditions and without the intervention of human beings. This is the first such documented case in the entire breeding grounds ofA. pomarina.

Published: January 2014

Introduction This study describes a new preperitoneal tunneling (PPT) method for inserting a peritoneal dialysis catheter (PDC), thereby lessening surgical complications and increasing the catheter's survival. Methods This new technique was used in 23 cases from December 2005 to January 2007 and followed up until March 2011 (63 months). The procedure was performed laparoscopically under local (16 cases) or general (7 cases) anesthesia by one surgeon. Catheter survival is reported by Kaplan-Meyer analysis. Results The catheters were mechanically obstructed in 2/23 cases (8.7%); and were withdrawn due to a peritonitis in 2 cases and inadequacy of peritoneal dialysis in 1 case. Ten patients received kidney transplantation and six died before completing this follow-up period. The patients still reaped the benefits of the PDC until receiving a kidney transplant or death. The 5-year survival rate of the catheter was 89%. No incidence of catheter migration, omental wrapping, herniation or leakage was noticed. Conclusion Preperitoneal tunneling is a simple and safe method for insertion of PDC, and can effectively prevent catheter migration, dislocation and omental wrapping.
Annotated catalogue of the bees described by Léon Provancher (Hymenoptera: Apoidea)
Authors: Sheffield Cory S. , Perron Jean-Marie 
Published: January 2014

AbstractThe bee species described and identified by Léon Provancher are reviewed. From 1882–1896, Provancher published accounts of 179 bee species from North America, which represent 145 currently recognised species. He proposed 67 new names, 21 of which are here considered valid; five species epithets proposed by Provancher were junior homonyms.The following are considered new junior synonyms of Provancher species:Andrena macrocephalaCockerell underAndrena nigripesProvancher;Pseudopanurgus nebrascensis(Crawford) underPseudopanurgus aestivalis(Provancher);Lasioglossum timberlakeiMcGinley underLasioglossum californicum(Provancher);Osmia kenoyeriCockerell underOsmia tarsataProvancher. Additional new synonymies made here include:Halictus distinguendusDalla Torre underLasioglossum coriaceum(Smith);Osmia parvaProvancher underOsmia atriventrisCresson;Stelis plena(Provancher) underStelis lateralisCresson;Coelioxys tristisProvancher underCoelioxys sodalisCresson;Diadasia tricinctaProvancher underEucera actuosa(Cresson).Lectotypes for 60 of Provancher's bee species are here designated, but type material for eight other species were not found. The taxonomic placement ofCalliopsis quadrilineataProvancher,Calliopsis interruptaProvancher,Hoplitis alboscopata(Provancher),Hoplitis imperfecta(Provancher), andDiadasia albovestitaProvancher within the bee fauna of North America remain unclear, and are here declarednomina oblita.
Early Eocene big headed flies (Diptera: Pipunculidae) from the Okanagan Highlands, western North America
Authors: Archibald S. Bruce , Kehlmaier Christian , Mathewes Rolf W. 
Published: January 2014

AbstractThree new species of Pipunculidae (Diptera) are described (one named), from the early Eocene (Ypresian) Okanagan Highlands of British Columbia, Canada and Washington State, United States of America: Metanephrocerus belgardeaenew species from Republic, Washington; and Pipunculidae species A and Pipunculinae species A from Quilchena, British Columbia. We re-describe the late Eocene (Priabonian) species Protonephrocerus florissantius Carpenter and Hull from Florissant, Colorado, United States of America, and assign it to a new genus proposed here, Priabonanew genus. Pipunculinae species A is the oldest known member of the family whose wing lacks a separated M2 vein; previously this had been known in species only as old as Miocene Dominican amber. This is a presumably derived character state that is predominant in modern species. Molecular analysis indicates an origin of the Pipunculidae in the Maastrichtian; the morphological and taxonomic diversity seen here in the Ypresian is consistent with an early radiation of the family. This is concordant with the radiation of Auchenorrhyncha, upon which they mostly prey, which is in turn associated with the early Paleogene diversification of angiosperm-dominated forests recovering from the K-Pg extinction event.
Coupling of winter climate transitions to snow and clouds over the Prairies

Published: January 2014

AbstractUsing data from 13 climate stations on the Canadian Prairies, together with opaque cloud cover and daily snow depth, to analyze the winter climate transitions with snow, we find that a snow cover acts as a fast climate switch. Surface temperature falls by about 10 K with fresh snowfall and rises by a similar amount with snowmelt, while the daily range of relative humidity falls to around 5–15% with snow cover. These are robust climate signals. For every 10% decrease in days with snow cover over the Canadian Prairies, the mean October to April climate is warmer by about 1.4 K. Stratifying by daily mean opaque cloud cover across snow transitions shows the rapid shift within 5 days from a diurnal cycle dominated by shortwave cloud forcing to one dominated by longwave cloud forcing. We calculate the change in the surface radiative budget with snow using surface albedo data from the Moderate Resolution Imaging Spectroradiometer and station longwave data. We find that with the fall‐winter snow transitions, the surface radiative heating is reduced by 50 Wm−2, with 69% coming from the reduced net shortwave flux, resulting from the increased surface albedo and a small increase in effective cloud albedo, and 31% from a reduced incoming longwave flux. This drop in surface radiative heating is sufficient to produce a drop in the surface radiometric skin temperature of 11 K. We find that in winter, the monthly mean diurnal climate is more closely coupled to the diurnal shortwave forcing than the mean diurnal climate.

Authors: Nordström Peter , Michaëlsson Karl , Gustafson Yngve , Nordström Anna 
Published: January 2014

ObjectiveTo investigate the association between traumatic brain injuries (TBIs) and the risk of young onset dementia (YOD), that is, dementia before 65 years of age.MethodsThe study cohort comprised 811,622 Swedish men (mean age = 18 years) conscripted for military service between 1969 and 1986. TBIs, dementia, and covariates were extracted from national registers. Time‐dependent exposures using Cox proportional hazard regression models were evaluated.ResultsDuring a median follow‐up period of 33 years, there were 45,249 men with at least 1 TBI in the cohort. After adjustment for covariates, 1 mild TBI (hazard ratio [HR] = 1.0, 95% confidence interval [CI] = 0.5–2.0), at least 2 mild TBIs (HR = 2.5, 95% CI = 0.8–8.1), or 1 severe TBI (HR = 0.7, 95% CI = 0.1–5.2) were not associated with Alzheimer dementia (AD). Other types of dementia were strongly associated with the risk of 1 mild TBI (HR = 3.8, 95% CI = 2.8–5.2), at least 2 mild TBIs (HR = 10.4, 95% CI = 6.3–17.2), and 1 severe TBI (HR = 11.4, 95% CI = 7.4–17.5) in age‐adjusted analysis. However, these associations were largely attenuated after adjustment for covariates (1 mild TBI: HR = 1.7; at least 2 mild TBIs: HR = 1.7; 1 severe TBI: HR = 2.6; p < 0.05 for all).InterpretationIn the present study, we found strong associations between YOD of non‐AD forms and TBIs of different severity. These associations were, however, markedly attenuated after multivariate adjustment. Ann Neurol 2014;75:374–381
Understanding lignin biodegradation for the improved utilization of plant biomass in modern biorefineries
Authors: Camarero Susana , Martínez María Jesús , Martínez Angel T. 
Published: January 2014

AbstractWood‐rotting fungi are the sole organisms in nature able to degrade the lignin polymer making the polysaccharide components of lignocellulose fully accessible. This process has been investigated for decades as a model for biotechnological application in the pulp and paper industry, animal feeding, and ethanol production. In the current lignocellulose biorefinery concept, ligninolytic fungi and the oxidoreductases (laccases and peroxidases) secreted by these fungi constitute powerful biotechnological tools for the complete utilization of plant biomass. The evolution of molecular biology, which brings into play specifically designed biological systems and on‐demand enzymes, together with the technological advances in processing of plant biomass, smoothes the way for a sustainable conversion of renewable feedstocks to new added‐value products, with lower energy costs and less environmental impact. The present study reviews some of the main achievements attained by our group in the field of lignin biodegradation that have contributed to: (i) better understanding of the mechanisms by which fungi delignify the lignocellulosic materials; and (ii) assessing the applicability of these ligninolytic systems to increase the efficiency of some industrial processes and to develop new means for sustainable and environmentally sound production of chemicals, materials, and fuels. © 2014 Society of Chemical Industry and John Wiley & Sons, Ltd

Published: January 2014

BACKGROUNDUnderstanding species differences in placental transfer of Fc‐containing biopharmaceuticals (particularly monoclonal antibodies) will improve human risk extrapolation from nonclinical embryo‐fetal development toxicity data.METHODSMaternal and fetal concentration data from 10, 15, 8, and 34 Fc‐containing biopharmaceuticals in the rabbit, rat, mouse, and cynomolgus monkey, respectively, from an industry survey were analyzed for trends in placental transfer.RESULTS AND CONCLUSIONSEmbryonic (before the end of organogenesis) exposure was assessed in one molecule each in rabbit, rat, and mouse, but detectable levels were present only in rodents. In rodents, fetal levels remained relatively constant from gestation day (GD) 16 and 17 until the end of gestation, while maternal levels decreased or remained constant in rat and decreased in mice. In rabbits, following a last dose on GD 19, fetal levels increased markedly in late gestation while maternal levels decreased. In the cynomolgus monkey, fetal levels increased substantially from GD 50 to 100 and were maintained relatively constant through parturition (approximately GD 165). Based on available data of both the monkey and rabbit, IgG1 molecules appeared to transfer more readily than other isotypes in late gestation. Across all species, there was no differential transfer based on pharmacologic target being soluble or membrane bound. Within each species there was a correlation between maternal and fetal exposure, suggesting it may be possible to predict fetal exposures from maternal exposure data. These nonclinical data (both temporal and quantitative aspects) are discussed in a comparative context relative to our understanding of IgG placental transfer in humans.
