On a comparison of Huber-Mises-Hencky with Burzynski-Pecherski equivalent stresses for glass body during nonstationary thermal load
No full textPhotoelastic and fem method in the fracture mechanics
No full textRed. serii : Wodziński, PiotrThe book contains results of numerical calculation and their comparison with
experimental tests carried out on the specimens CT. Crack propagate until damage
specimen was achieved. The angle between the direction of crack propagation and the
direction of the artificial crack was measured.
Author during numerical investigations compare Burzynski and Huber-MisesHencky
hypothesis. The Burzynski hypothesis gives very good results for brittle
materials which has different properties for tensile and compression it means that
relationship between limit stress for compression Re to limit stress for tension Rm is
greater than 1 (for example: epoxy resign, cast iron).
Influence of relation R.!Rm on angle of crack propagation was carried out. The
results of investigation gives information that for relation R.!Rm greater than 1,3 the
value of angle of crack propagation is constant, and its value is about 76°.
The experimental investigation is solved by photoelastic method. The numerical
results were obtained using finite element method package ANSYS. The problem is
solved by "element birth and death" method.
Results of investigations of cracking of reinforced specimens are presented
Book Review – \u3ci\u3eNew New Media\u3c/i\u3e by Paul Levinson
No full textIt’s increasingly difficult to keep up with the rapid growth of new forms of communication created by the Internet. Change happens so fast that even a relatively new format—such as Wikipedia, launched in 2001—seems old and familiar just ten years later.
Paul Levinson, an author and professor of communication and media studies at Fordham University, says one characteristic that distinguishes “new new media” from simple “new media” is that in the newer form the consumer is also a producer
Regret the error, but who admits it?
No full textCorrecting errors is simple and quick online. For Craig Silverman, that ease raises ethical issues. The author of the popular Regret the Error book and website believes news sites too often scrub away errors without acknowledging the mistakes. But what\u27s the most ethical way to handle those errors? Should the story be updated without explaining that the original error occurred, what Silverman and others call scrubbing ? Or should the fix be made with a note appended to the original article explaining that an error had been made
The Arrhenia peltigerina complex—preliminary report
No full textPhylogenetic study of Arrhenia peltigerina revealed a complex of seven divergent clades. Type specimens of Agaricus peltigerinus and Omphalina cupulatoides fell into separate clades; the latter was recombined as Arrhenia cupulatoides. Four clades were described as new species: Arr. baltica, Arr. fennoscandica, Arr. mohniensis, and Arr. talpoides; the fifth, with only a single specimen, was left formally undescribed. These cryptic species are uncommon—more so in North America than Scandinavia—and collections are often misidentified. Spore measurements separated Arr. baltica from the others by its narrower spores; average measurements help separate some species a bit better than ranges. So far, Arr. peltigerina was found only in North America, Arr. mohniensis and Arr. talpoides in both Europe and North America, and the remainder only in Europe. The host species of Peltigera was P. hymenina for Arr. cupulatoides, P. rufescens for Arr. baltica, and varied for the others. All but one collection came from soil over calcareous bedrock. Small sample size does not permit assigning high confidence to noted interspecific differences; these await confirmation by greater experience from future study.The presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Introduction
The amount of research on contaminants of
emerging concern (CECs) continues to grow as
awareness of their presence in the environment
increases. A search of CEC literature reveals
the primary focus of CEC research has been on
quantifying presence and determining extent.
There is currently limited research on the
physiological effects of CECs. Of the research
on organismal effects, almost the entirety of it is
based on laboratory studies leaving a large data
gap on observed environmental effects. Recent
conservation efforts for lake sturgeon (Acipenser
fulvescens) using streamside rearing facilities
(SRFs) offers an applied feld-based situation for
investigating the relationship between CECs and a
managed species of interest.
Lake sturgeon are long-lived, migratory, freshwater
fsh that are native to North America. Their native
range includes the Mississippi River, Great Lakes,
and Hudson Bay Basins. However, a combination
of biological and anthropogenic factors has led
to the species being listed as of special concern,
threatened, or endangered in 19 of the 20 states
in its native range (Bruch et al. 2016, IDNR).
Anthropogenic reasons for their decline include
being regarded as a nuisance fsh, over-harvesting in
the late 1800s, habitat loss, construction of barriers
to spawning migration, and pollution (Harkness
and Dymond 1961). Biological factors include high
juvenile mortality, low recruitment, delayed sexual
maturity, and spawning periodicity of 1 to 3 years for
males and 4 to 9 years for females (Peterson et al.
2007).
To increase the success of population restoration
efforts and downlist species’ status, SRFs are
being used across the Great Lakes basin, but it is
currently unclear if exposure to CECs at SRFs
could be impeding the success of rearing goals.
Figure 1. Lake sturgeon genetic stocking units of the Great Lakes (from Welsh et al. 2010)
Introduction 1
SRFs are fxed or mobile hatcheries stationed
adjacent to rivers that utilize ambient river water
for rearing. These facilities have smaller production
capabilities than traditional hatcheries but maintain
the benefts of being able to treat for pathogens,
protection from predation, guarantee of food, and,
at some facilities, control of water temperature. In
addition, SRFs have a distinct advantage of being
able to rear fsh in water from the location where
they will be released. This aspect is especially
important in migrating fsh that are subject to
olfactory imprinting to the chemical composition
of their natal waters. Research on the related
Russian sturgeon (Acipenser gueldenstaedtii)
indicates that imprinting in sturgeon occurs during
the prolarval stage as prolarvae are transitioning
to exogenous feeding (Boiko et al. 1993; Boiko and
Gregor’yan 2002). If this timing is representative
of lake sturgeon, then imprinting for lake sturgeon
occurs while the fsh are in the SRFs or hatcheries.
In a traditional hatchery, the sturgeon would then
imprint to waters unconnected to their release
waters, potentially preventing them from returning
to desirable spawning areas.
Lake sturgeon in the Great Lakes have been
genetically analyzed and assigned to six distinct
Genetic Stocking Units (GSUs; Welsh et al. 2010;
Figure 1). Mature fsh of different GSUs may reside
within the same body of water during non-spawning
periods. The inability to home in on their natural
spawning ground potentially results in fsh spawning
outside of their natural GSU and can lead to
reduction of ftness through outbreeding depression.
Outbreeding depression effects include reduced
countergradient variation growth rates (Power and
McKinley 1997), changes in embryo development
time and survival (Granath et al. 2004), decreased
survival in hybrid offspring (Gilk et al. 2004), and
increased infection and disease susceptibility
(Goldberg et al. 2005).
Among the limited laboratory research on CECs,
there is indication of potential to negatively impact
fsh populations in the Great Lakes Basin (GLB).
For example, polybrominated diphenyl ether
(PBDE) compounds, found throughout the GLB
(Choy et al. 2017, Kolpin et al. 2002, Lee et al.
2015) have been shown to interfere with thyroid
hormone signaling (Schriks et al. 2007, Lema et al.
2008). Hydroxylated PBDEs share similar chemical
structures to triiodothyronine and thyroxine (Ren
et al. 2013) and have been shown to compete with
thyroxine for binding sites on thyroid transport
proteins, thereby reducing transport of thyroxine
(Meerts et al. 2000). This disruption potentially
reduces the parental supply of hormones to
developing eggs, which may impair imprinting,
growth, and survival.
Analysis of environmental contaminant effects is
complicated since chemical interactions can alter the
magnitude of effect. Single chemicals have not been
observed in the GLB but rather complex mixtures
exist, highlighting the importance of conducting feld
based studies which assess actual environmental
conditions and effects.
The goal of this study is to assess the health,
growth, and development of larval and age-0 lake
sturgeon and compare among rearing waters with
different exposure levels to CECs.

Methods
Site Selection — There are currently nine SRFs in
operation in the Great Lakes Basin (Figure 3). The
suitability of an SRF for this study was determined
by the suspected presence of CECs, based on
surrounding land usage, and the ability of facility
managers to accommodate research needs. In 2017,
the facilities on the Cedar River near Cedar River,
MI; the Whitefsh River near Rapid River, MI;
and the Black River at the Black River Sturgeon
Research Facility in Onaway, MI were selected. The
Genoa National Fish Hatchery (NFH) in Genoa,
WI was also selected for study as a reference for
comparison between traditional rearing, which has
a greater rearing capacity but may not facilitate
larval imprinting, and streamside rearing. In
2018, a second set of facilities was studied in order
to include additional exposure profles. This set
included the Milwaukee River near Newburg, WI;
the Kewaunee River at the Besadny Anadromous
Fish Facility in Kewaunee, MI; and the Maumee
River at the Toledo Zoo in Toledo, OH. The Genoa
NFH and Black River Sturgeon Research Facility
were also studied for an additional year in 2018 for
repeatability and to analyze temporal variations.

hydrologic divide of the Great Lakes Basin.
Methods 3
Site Confgurations — The SRFs utilized in the study
generally used a design as described in Holtgren
et al. (2007). Briefy, they consisted of an intake
pump to pull water from an adjacent river through
a screened intake. Water was then pumped through
a flter to reduce suspended solids. Following
fltration, water was sent to a raised head tank
which gravity-fed water to maintain a consistent
water supply to the rearing tanks. Flow to each
tank was individually controlled by a ball valve
installed in the outlet pipe that fed each tank. Water
was drained from the tanks through an elevated
drainpipe and returned to the source river. The
set up for the Genoa NFH was similar with the
notable exception that instead of drawing source
water from an adjacent river water was drawn from
on-site wells, recirculated through a hatchery pond
and fltered to maintain optimal temperature for
growth and improved water quality. Additionally,
the Genoa NFH, Black River Sturgeon Research
Facility, and Maumee River SRF were housed in
fxed buildings instead of the converted trailers
described in Holtgren et al. (2007). Individual
design specifcations are presented in Table 11
Appendix A for comparison. Water temperatures
were collected using HOBO Pendant Temperature/
Light Data Loggers (Onset Computer Corporation
Model UA-002-08) placed in the head tanks at
all locations except at the Black River Sturgeon
Research Facility where it was placed in one of the
rearing tanks instead. Loggers were programmed to
collect hourly temperature readings throughout the
entire rearing period. Data were extracted from the
loggers using the HOBOware software suite Version
3.7.10 (Onset Computer Corporation).
Egg Collection — In 2017, gametes were collected
from the south side of the dam on the Peshtigo River
in Peshtigo, WI. In 2018, gametes were collected
from the Wolf River below the dam at Shawano, WI

“The Kmicic Boys”. A draft on one of the episodes of Tadeusz Konwicki’s <i>Sennik współczesny</i> [The Contemporary Dream Book]
No full textArtykuł jest poświęcony tematowi okrucieństwa przedstawionemu w najwybitniejszej chyba powieści Konwickiego. Autor analizując sposób przedstawienia tego tematu w Senniku… dochodzi do wniosku, iż pisarz opisując cierpienie zawsze posługuje się obrazami. Sam ten temat bowiem wymyka się opisowi, tradycyjnej literackiej reprezentacji (tu jest zgodny ze zdaniem znanego badacza tego zagadnienia Wolfganga Sofsky’ego). Szkic nie zamyka się na prezentacji tego motywu w jednej powieści Konwickiego – autor pokazuje jego funkcje i ewolucję także w późniejszej twórczości (Nic albo nic; Kilka dni wojny, o której nie wiadomo, czy była) – tu zauważona zostaje wartość „nadziei”. Artykuł omawia ponadto „kłopoty” PRL-owskiej krytyki literackiej z zaprezentowaną przez pisarza kresową partyzancką wojną – piszący o tej powieści wyraźnie unikają głębszej analizy tego tematu. Marcinów kończy swój tekst postawieniem tezy, że powieściową fabułę i realia historyczne łączy motyw zdrady – tu przypomniane zostają losy wybitnego dowódcy polskiej partyzantki na Kresach, porucznika Antoniego Burzyńskiego (pseud. Kmicic).The aim of the following paper is to analyze the theme of cruelty in what is considered to be the greatest novel written by Tadeusz Konwicki. The author argues that the way it is pictured focuses almost exclusively on imagery, as the theme itself is beyond traditional literary description (as stated before by the scholar Wolfgang Sofsky). The article focuses not the subject within this one single work only, but also introduces the reader to its evolution and later use in other novels (such as Nic albo nic [Nothing or nothing] or Kilka dni wojny, o której nie wiadomo, czy była [A Few Days of the War We Were Never Sure Actually Happened]) – which introduce the value of ‘hope’ within the theme. Additional attention is drawn to the ‘issues’ Communist Poland’s literary criticism had with the way the writer presented partisan movements during war in the Eastern Borderlands clearly avoiding in-depth analysis of the motif. Marcinów concludes that both Sennik współczesny [The Contemporary Dream Book] and the historical period the novel is set within share the significance of the theme of betrayal and links it with the fate of a prominent partisan leader in the Eastern Borderlands, lieutenant Antoni Burzynski, codename Kmicic
