MAIC-2, a latitudinal model for the Martian surface temperature, atmospheric water transport and surface glaciation
No full textThe Mars Atmosphere-Ice Coupler MAIC-2 is a simple, latitudinal model, which consists of a set of parameterisations for the surface temperature, the atmospheric water transport and the surface mass balance (condensation minus evaporation) of water ice. It is driven directly by the orbital parameters obliquity, eccentricity and solar longitude (Ls) of perihelion. Surface temperature is described by the Local Insolation Temperature (LIT) scheme, which uses a daily and latitude-dependent radiation balance. The evaporation rate of water is calculated by an expression for free convection, driven by density differences between water vapor and ambient air, the condensation rate follows from the assumption that any water vapour which exceeds the local saturation pressure condenses instantly, and atmospheric transport of water vapour is approximated by instantaneous mixing. Glacial flow of ice deposits is neglected. Simulations with constant orbital parameters show that low obliquities favour deposition of ice in high latitudes and vice versa. A transient scenario driven by a computed history of orbital parameters over the last 10 million years produces essentially monotonically growing polar ice deposits during the most recent 4 million years, and a very good agreement with the observed present-day polar layered deposits. The thick polar deposits sometimes continue in thin ice deposits which extend far into the mid latitudes, which confirms the idea of “ice ages” at high obliquity

Fragmentos manuscritos hebraicos del Arxiu Municipal de Girona sobre enfermedades genitales y sus remedios: edición, traducción y glosario
No full textTwo bifolios and one fragment from among the fragments of medical and pharmacological texts found in the binding of the Llibre d’Àpoques (containing the receipts of payments made by the clavario on behalf of the municipal council) dating from 1380 from the Municipal Archives of Girona, are analyzed because of their linguistic and historial value. The writing and the presentation suggest that they share the same author. Relying on content details, the author presents a probable arrangement of the pages’ original order. Many of the botanical terms are given in the Catalan language (they appear in the translation in cursive letters). The rendition of the Catalan words in Hebrew letters enables us to know their pronunciation at the time.Estudio de varios fragmentos manuscritos que contienen textos médicos y farmacológicos recuperados de las cubiertas de un Llibre d’àpoques (recibos de los pagos realizados por el clavario en nombre del concejo) del año 1380 del Arxiu Municipal de Girona. Los dos bifolios y el fragmento estudiados tratan de dolencias genitales en mujeres y en varones y de sus remedios y pertenecen al mismo manuscrito y eventualmente a un mismo autor. Los textos se han ordenado siguiendo un criterio temático con objeto de reconstruir la disposición original. El texto está en hebreo y contiene términos técnicos en lengua romance catalana (en cursiva, en la traducción), y permite elaborar un glosario de farmacopea de gran valor lingüístico e histórico, además de aportar información sobre su pronunciación

No full textThe Poudre River: history of collaboration over conflict
No full textPresented at the Fall 2014 Center for Collaborative Conservation (https://collaborativeconservation.org/) Seminar and Discussion Series, "Perspectives on the Poudre: Working River/Healthy River", September 9, 2014, Colorado State University, Fort Collins, Colorado. This fall semester's bi-weekly Seminar and Discussion Series focuses on the Poudre River and its watershed, its ecological needs, and how it is used to supply water for agriculture and urban needs. Presenters will highlight their topics and engage participants in dialogue. The series will culminate in a "world café" - campus and community open dialogue about the Poudre.Tom Cech was born and raised on a farm near Clarkson, Nebraska, graduated from Kearney State College with a Bachelor of Science Degree in Math Education, and later received a Masters Degree in Community and Regional Planning from the University of Nebraska – Lincoln. He was Executive Director of the Central Colorado Water Conservancy District in Greeley, taught water undergraduate and graduate level water resources courses at the University of Northern Colorado and Colorado State University, and is now the Director of the One World One Water (OWOW) Center for Urban Water Education and Stewardship at Metropolitan State University of Denver. Tom wrote "Principles of Water Resources: History, Development, Management and Policy," published by John Wiley & Sons - currently in its 3rd edition. Tom also recently published "Introduction to Water Resources and Environmental Issues," (co-author Dr. Karrie Pennington) with Cambridge University Press, and "Colorado Water Law for Non-Lawyers," (co-author P. Andrew Jones) with the University Press of Colorado. He has also completed histories of the Colorado Water Conservation Board and the Colorado State Engineer's Office with Bill McDonald and Dick Stenzel, respectively.Poster presentation.The meeting was held on a hot, dry summer day in 1874. Two groups of irrigators, from the downstream Union Colony (Greeley) and the new agricultural community in upstream Fort Collins - came armed with guns. The neutral Eaton Schoolhouse was too small to hold everyone, so people crammed the doorway. Most were Civil War veterans, and they all had a problem. "How would the two feuding groups divide the trickle of Cache la Poudre River water the remainder of the irrigation season - would it be based on "greatest need" or by priority (who dug their ditch first)?" The Union Colony delegates didn't like the greatest need idea, and they "hurled defiance in hot and unseemly language." The debate escalated with the Union Colony irrigators threatening to dig new irrigation ditches upstream of Fort Collins to choke off their water supply. The Fort Collins contingent objected to their uncooperative reaction. Then the meeting got ugly. One man, unable to bear the tension any longer, stood up and yelled, "Every man to his tent! To your rifle and cartridges!" It was a flashpoint in Colorado's water history. Were irrigators shot at this meeting? Who tried to calm the crowd and come up with a workable compromise for water management on the Cache la Poudre River? Tom Cech will explain this and more

Sprawozdanie z działalności jako narzędzie raportowania danych niefinansowych z zakresu CSR
No full textThe on-going globalisation and changes in the perception of the corporate place and role in the social environment gave rise to the growth in significance of issues of its social responsibility. At the same time, a heavier focus of stakeholders on non-financial aspects of operation, in particular with regard to the environmental, staff and social questions requires the modification of the process of corporate reporting. This study is a short analysis and an attempt to answer the issue concerning the awareness of benefits from corporate communication of their socially responsible activities and the degree of use of the activity report in the process of CSR non-financial data reporting. To solve the presented research problem the author applied the method of analyses the content of legal regulations and literature, interviews and the conclusion method.Postępująca globalizacja oraz zmiany w zakresie postrzegania miejsca i roli przedsiębiorstwa w środowisku społecznym doprowadziły do wzrostu znaczenia zagadnień dotyczących jego społecznej odpowiedzialności (Corporate Social Responsibility, CSR). Jednocześnie większa koncentracja interesariuszy na pozafinansowych aspektach działalności, szczególnie dotyczących kwestii środowiskowych, pracowniczych i społecznych, wymusza modyfikację procesu raportowania i sprawozdawczości przedsiębiorstw. Niniejsza publikacja jest krótką analizą i jednocześnie próbą odpowiedzi na pytanie dotyczące świadomości korzyści płynących z komunikowania przez przedsiębiorstwa ich działań w zakresie społecznej odpowiedzialności oraz stopnia wykorzystania sprawozdania z działalności w procesie raportowania danych niefinansowych dotyczących CSR. Do rozwiązania przedstawionego problemu badawczego wykorzystano metodę analizy treści regulacji prawnych i literatury, wywiad oraz metodę wnioskowania
Value of post-mortem skeletal radiographs in the diagnosis of fetal anomalies and spontaneous abortions

Diskussion
LiteraturverzeichnisÜber einen Untersuchungszeitraum von 7 Jahren wurden bei Feten aus
Spontanaborten und Schwangerschaftsabbrüchen aus der Universitätsfrauenklinik
Charité, Berlin neben der Autopsie Röntgenuntersuchungen durchgeführt. Diese
Aufnahmen wurden von einer in der Diagnostik von skelettalen Fehlbildungen
erfahrenen Radiologin (Frau Prof. Dr. med. Stöver) beurteilt, mit Beschreibung
der Abweichung von der Norm und wenn möglich eine endgültige Diagnose
gestellt. Dabei ließen sich nicht nur die Skelettdysplasien klassifizieren,
sondern die Veränderungen konnten auch zur Erweiterung der Abklärung der
Todesursache genutzt werden. Insgesamt kamen die Befunde von 200 Feten zur
Auswertung, dabei fand sich bei 96 männlichen und 104 weiblichen Feten eine
ausgewogene Geschlechtsverteilung. Es zeigte sich im Vergleich mit Studien aus
anderen Ländern ein höherer Prozentsatz an Skelettdysplasien, nämlich bei 13%
der Fälle. Angelehnt an die Untersuchungen von Bourlière-Najean et al.
erfolgte eine Unterscheidung in größere und kleinere Anomalien, wobei kleinere
Anomalien (Unter- und Überzähligkeit von Rippen, verkürzte Phalangen) in 15%
der Fälle auftraten, größere Anomalien (andere Skelettanomalien, die nicht in
die erste Gruppe fallen) wurden in 51% der Fälle beobachtet. Daneben wurden
zusätzlich die Veränderungen an den jeweiligen Skelettabschnitten ausgewertet,
unter Berücksichtigung von Agenesien, Dislokationen, Verbiegungen,
Verkürzungen/Verbreiterungen, Verlängerungen/Verschmälerungen,
Matrixstörungen, Frakturen, metaphysären Veränderungen an den Extremitäten,
sämtliche möglichen Veränderungen an Zahl, Dysplasie, Spaltbildungen, etc. an
den Wirbelkörpern und auch pathologische Verkalkungen sowie auffällige
Veränderungen der nicht-skelettalen Weichteile. Unter besonderer
Berücksichtigung genetischer Veränderungen erfolgte die Klassifikation der
vorhandenen Stigmata. Es lag bei 1/8 der Feten eine chromosomale Aberration
vor. Bei einer Unzahl von Klassifikationssystemen, die einen Spontanabort oder
pränatal detektierte Anomalien versuchen zu kategorisieren, verwundert es,
dass der Röntgenaufnahme des Feten keine angemessene Bedeutung zukommt. In der
vorliegenden Auswertung konnte gezeigt werden, dass ein gewisser Teil der von
klinischer Seite unklaren Diagnosen durch die radiologischen
Zusatzinformationen eingeordnet werden konnte. Dabei ist zu betonen, dass das
nicht allein die echten Skelettdysplasien betrifft, sondern auch die
Einordnung in Syndrome teilweise erst durch die Aussage der Röntgenaufnahme
möglich wird. Beides ist für die nachfolgende humangenetische Beratung von
entscheidender Bedeutung.X-ray images and autopsies of human fetuses from induced and spontaneous
abortions from the department of gynaecology of University Hospital Charité,
Berlin were compared over a period of 7 years. All images were read by an
experienced radiologist (Prof. Dr. Stöver), who is especially trained in
evaluating bone dysplasias. Images were analysed to find a final diagnosis to
explain the cause of the abortions and fetal malformations, resp. 200 fetuses
were included, 96 male and 104 female subjects demonstrated the equal sex
distribution. Compared to earlier studies done abroad, a higher percentage of
bone dysplasias were found, which were detected in 13% of cases. Using a
similar approach as Bourlière-Najean et al. applied, anomalies were divided
into minor and major variants, where minor meant supernumerary or absent ribs
or shortened phalanges and major meant more serious malformations and bone
matrix alterations. Minor abnormalities were detected in 15% of cases, whereas
major ones made up 51% of cases. Moreover the location of anomalies were
grouped, attention was paid to agenesis, dislocations, tilting, shortening,
widening, elongation, narrowing, conspicuous bone matrix, fractures,
metaphyseal changes of the extremities, alterations of numbers, contours,
clefts of the vertebrae, and pathologic calcifications. The soft tissues were
evaluated as well. Considering genetically determined changes, grouping the
anomalies into classifications was attempted. 1 out of 8 fetuses showed
chromosomal aberrations. There are more than a dozen of classification
systems, attempting to group causes of spontaneous abortions and prenatally
detected anomalies, however, the role of X-raying the fetuses is still not
fully appreciated. With this analysis the author can show, that with the help
of X-ray images many uncertain cases can be further subgrouped and/or assigned
to syndromes. In case of skeletal dysplasias, the X-ray is indisputable. In
either case, imaging is of high importance in the context of genetic
counselling
