A Summary of Archaeological Excavations from 1983-1986 at the Green Family Print Shop, 18AP29, Annapolis, Maryland

18AP29, the Green Family Printshop, also known as the Jonas Green site, was excavated from 1983 to 1986 by Archaeology in Annapolis and Historic Annapolis Foundation. The site is not only the home of a significant figure in colonial Maryland but is also the location of one of the first colonial printing operations in Maryland. This site represents an important pre-industrial business in Annapolis. While this domestic site is complicated and rich, one of the most fascinating aspect of 18AP29 is the discovery of a large quantity of printers' type. Extensive analysis of the printers' type and documentary research on one of the print shop's products, the colonial newspaper, the Maryland Gazette, provides insights into the print culture which was developing during the 18th and 19th centuries. This report summarizes the stratigraphic analysis, minimum vessel counts, and faunal analysis. It provides some description of the printers' type.

Phytochrome diversity in green plants and the origin of canonical plant phytochromes.

Phytochromes are red/far-red photoreceptors that play essential roles in diverse plant morphogenetic and physiological responses to light. Despite their functional significance, phytochrome diversity and evolution across photosynthetic eukaryotes remain poorly understood. Using newly available transcriptomic and genomic data we show that canonical plant phytochromes originated in a common ancestor of streptophytes (charophyte algae and land plants). Phytochromes in charophyte algae are structurally diverse, including canonical and non-canonical forms, whereas in land plants, phytochrome structure is highly conserved. Liverworts, hornworts and Selaginella apparently possess a single phytochrome, whereas independent gene duplications occurred within mosses, lycopods, ferns and seed plants, leading to diverse phytochrome families in these clades. Surprisingly, the phytochrome portions of algal and land plant neochromes, a chimera of phytochrome and phototropin, appear to share a common origin. Our results reveal novel phytochrome clades and establish the basis for understanding phytochrome functional evolution in land plants and their algal relatives.

Evaluating the Feasibility of Implementing a Green Roof Retrofit on Pitched Residential Roofs

Green roofs are one solution to stormwater runoff which is a major environmental problem. However, the majority of green roofs are primarily implemented on flat roofed commercial buildings and not residential homes with sloped roofs. Team SO GREEN designed a light-weight green roof system retrofit for residential homes. Between June and November 2014, green roof performance data was collected and compared between the designed sloped roofs and a non-sloped control. The sloped design performed well and one test slope was improved with a recirculating irrigation system. An economic analysis was made and a focus group determined preliminary consumer interest, aesthetic preferences, and barriers. This study enriches the body of knowledge regarding bringing green roof systems to the residential home market.

Infiltración del agua en un suelo de un establecimiento de producción animal intensiva : factibilidad de predicción de la misma empleando el modelo de Green y Ampt y funciones de pedotransferencia

El objetivo de este trabajo fue evaluar la eficiencia del modelo de Green-Ampt en la predicción de la infiltración del agua en el suelo haciendo uso de funciones de pedotransferencia (FPT) de Saxton y Rawls (SR), Wösten y Nemes (WN) y las del programa Rosetta (ROS) y analizar el efecto de la carga animal sobre este proceso, por medio de los modelos empíricos de Mezencev (Mez) y el de Swarzendruber (SW), en un establecimiento de producción animal. El estudio se llevó a cabo en un establecimiento sito en la localidad de Marcos Paz, Pcia. de Bs.As. Se eligieron dentro del predio, cuatro grupos de sectores de acuerdo a la intensidad de carga (Ic) : nula (testigo), media, alta y muy alta. El proceso de infiltración se relevó por medio de anillos de Muntz hasta alcanzar la tasa de infiltración básica (TIB). Se tomaron muestras para determinar la densidad aparente (DA), carbono total (CT), humedad gravimétrica (H), conductividad hidráulica saturada (Ks) y se midió la resistencia a la penetración (Rp). Se llevaron a cabo en total 70 ensayos de infiltración y los resultados permitieron concluir que: 1) La carga animal produjo solamente efectos notorios de disminución de la TIB para muy alta Ic. 2) El modelo de SW resultó describir el fenómeno desde el punto de vista físico mejor que el de Mez. 3) La predicción del modelo de GA resultó satisfactoria utilizando las FPT de WN, pero no con las de SR o ROS. 4) Los valores de Ks medidos resultaron entre 5 y 10 veces mayores que los correspondientes de TIB. 5) La TIB dependió sólo de las variables Ic, DA y CT en un modelo de regresión lineal
