Survival at the frontier of Holy War: political expansion, crusading, commerce and the medieval colonizing settlement at Biała Gora, North Poland

Between the eleventh and thirteenth centuries AD, the Lower Vistula valley represented a permeable and shifting frontier between Pomerelia (eastern Pomerania), which had been incorporated into the Polish Christian state by the end of the tenth century, and the territories of western Prussian tribes, who had resisted attempts at Christianization. Pomeranian colonization eventually began to falter in the latter decades of the twelfth and early thirteenth centuries, most likely as a result of Prussian incursions, which saw the abandonment of sites across the borderland. Subsequently, the Teutonic Order and its allies led a protracted holy war against the Prussian tribes, which resulted in the conquest of the region and its incorporation into a theocratic state by the end of the thirteenth century. This was accompanied by a second wave of colonization, which resulted in the settlement pattern that is still visible in the landscape of north-central Poland today. However, not all colonies were destroyed or abandoned in between the two phases of colonization. The recently excavated site of Biała Góra, situated on the western side of the Forest of Sztum overlooking the River Nogat, represents a unique example of a transitional settlement that included both Pomeranian and Teutonic Order phases. The aim of this paper is to situate the site within its broader landscape context which can be characterized as a militarized frontier, where, from the later twelfth century and throughout much of the thirteenth century, political and economic expansion was combined with the ideology of Christian holy war and missionary activity. This paper considers how the colonists provisioned and sustained themselves in comparison to other sites within the region, and how Biała Góra may be tentatively linked to a documented but otherwise lost outpost in this volatile borderland.

Missionary children: The French Holy Childhood Association in European context, 1843-c.1914

In the mid-nineteenth century, thousands of children in Europe and beyond were organized into battalions of fundraisers for overseas missions. By the end of the century these juvenile missionary organizations had become a global movement, generating millions of pounds in revenue each year. While the transnational nature of the children’s missions and publications has been well-documented by historians, the focus has tended to be on the connections that were established by encounters between the young western donors, missionaries overseas and the non-western ‘other’ constructed by their work. A full exploration of the European political, social and cultural concerns that produced the juvenile missionaries movement and the trans-European networks that sustained it are currently missing from historical accounts of the phenomenon. This article looks at the largest of these organizations, the Catholic mission for children, the French Holy Childhood Association (L’Œuvre de la sainte enfance), to understand how the principles this mission sought to impose abroad were above all an expression of anxieties at home about the role of religion in the family, childhood and in civil society as western polities were modernizing and secularizing in the nineteenth century.

The role of the seed coat in phytochrome-controlled seed germination in Lactuca sativa L. cv. Grand Rapids

The effect of scarification with sodium hypochloride on light sensitivity in seeds of Lactuca sativa L. cv. Grand Rapids is presented in the paper. Light-requiring lettuce seeds germinated in both dark and continuous light after scarification and 36 degrees C pre-incubation restored light sensitivity at 25 degrees C. Curves of dose-response indicated that chemical scarification induced a change in the control of seed germination from Low Fluence Response to the Very Low Fluence Response. Pre-incubation at 36 degrees C return the control to the Low Fluence Response of phytochrome action.

Subcellular localization of the coat protein in tobacco cells infected by cucumber mosaic virus isolated from Catharanthus roseus

Electron microscopy and immunolabelling with antiserum specific to cucumber mosaic virus coat protein were used to examine tobacco leaf cells infected by cucumber mosaic virus isolated from Catharanthus roseus (CMV-Cr). Crystalline and amorphous inclusions in the vacuoles were the most obvious cytological modifications seen. Immunogold labelling indicated that the crystalline inclusion was made up of virus particles and amorphous inclusions contained coat protein. Rows of CMV-Cr particles were found between membranes of dictyosomes, but membranous bodies and tonoplast-associated vesicles were not evident. Virus particles and/or free coat protein were easily detected in the cytoplasm by immunolabelling. No gold labelling was found within nuclei, chloroplasts and mitochondria.

Coat protein and RNAs of Cole latent virus are not present within chloroplasts of Chenopodium quinoa-infected cells

O vírus latente da couve (Cole latent virus, CoLV), gênero Carlavirus, foi estudado, por microscopia eletrônica de transmissão e técnicas bioquímicas, em relação à ultra-estrutura das células infetadas de Chenopodium quinoa, e de sua associação com os cloroplastos. O CoLV foi observado como partículas dispersas pelo citoplasma entremeadas com vesículas membranosas e ribossomos e/ou como densas massas de partículas. Estes partículas reagiram por imunomarcação com anti-soro policlonal para o CoLV. Morfologicamente, cloroplastos, mitocôndrias e núcleos mostraram-se inalterados e partículas virais não foram encontradas dentro dessas organelas. Entretanto, agregados de partículas virais foram freqüentemente vistos em associação com a membrana externa dos cloroplastos e ocasionalmente com peroxissomos. Cloroplastos foram purificados em gradiente de Percoll e as proteínas e os RNA foram extraídos e analisados, respectivamente, por Western blot e Northern blot. Proteína capsidial e RNA associados ao CoLV não foram detectados nessa organela. Os resultados aqui obtidos indicam que a associação CoLV/cloroplastos, observada nos estudos de microscopia eletrônica, é possivelmente um evento casual dentro da célula hospedeira e que o vírus não se multiplica dentro dessa organela.

Hair coat characteristics and sweating rate of Braford cows in Brazil

This paper deals with the effects of hair coat characteristics on the sweating rate of Brazilian Braford cows and estimation of heritabilities and genetic correlations of these traits. Data (n=1607) on hair length, coat thickness, hair diameter, number of hairs per unit area, coat reflectance and sweating rate were recorded from heifers and cows of a commercial herd managed on range under extensive system. The data were analyzed considering the following effects on the model for hair coat traits: classes of sires and contemporary groups; linear effects of month and genotype; linear and quadratic effects of age. The effect of sire was important (P<0.05) for all hair coat traits, except for number of hairs; contemporary groups affected (P<0.05) all hair coat traits; the effect of sampling month was important (P<0.05) for hair length and reflectance; genotype affected (P<0.05) hair length, diameter and coat reflectance; the quadratic effect of age was important (P<0.05) only for coat reflectance. Two models were used to analyze the sweating rate. The first model considered the following fixed effects: classes of contemporary groups and sires; linear effect of genotype, coat thickness, hair length, hair diameter, number of hairs, coat reflectance; linear and quadratic effects of time of day, age, air temperature, partial vapour pressure and radiant heat load. The second model used for the sweating rate considered the same fixed effects for the first model, except that the hair coat characteristics were adjusted for important effects used in the models to analyze hair coat traits. All meteorological factors and contemporary groups were important (P<0.05) on variation of sweating rate in both models. The Restricted Maximum. Likelihood (REML) method was used to estimate variance and covariance components under the sire model. Results included heritability estimates in narrow (h(2)) and broad (H) sense for single-trait analyzes: hair thickness (h(2)=0.16; H-2=0.26); hair length (h(2)=0.18; H-2=0.39); number of hairs (h(2)=0.08 +/- 0.07; H-2=0.08 +/- 0.07); hair diameter (h(2)=0.12 +/- 0.07; H-2=0.12 +/- 0.07); coat reflectance (h(2)=0.30; H-2=0.42); and sweating rate (h(2)=0.10 +/- 0.07; H-2=0.10 +/- 0.07). In general, the genetic correlations between the adaptive traits were favorable as for the direction to select for adaptation in tropical environment; however, they presented high standard errors. The results of this study imply that hair coat characteristics and sweating ability are important for the adaptability to heat stress and they must be better studied and further considered for selection for genetic progress of adaptation in tropical environment.

Environmental and genetic variation of the effective radiative properties of the coat of Holstein cows under tropical conditions

Morphological characteristics, coat effective radiative properties, and the percentage of white colour were measured in the coats of 973 Holstein cows, and estimates of the genetic parameters were obtained for these traits, except morphological characteristics. The results showed that white coats are more dense with long, thin hairs, while the black coats are less dense with short, thick hairs. Effective transmissivity is greater in the less-dense coats with short, thin hairs, independently of coat colour. Effective reflectivity depends more on the variation in the radiative properties of the coat and skin surface rather than on the morphological characteristics of the coat. Effective absorptivity is greater in black and dense coats with long, thick hairs, than in the white and less-dense coat with short, thin hairs. All heritability estimates were of low magnitude, except for the percentage of white coat colour.
