I want to stop talking about digital archeology. I want to continue doing archeology digitally. This is what Frontiers in Digital Archaeology is about. I echo (Morgan and Eve, 2012; p. 523) the statement that “we are all digital archaeologists.” This statement wants to be radical but is in fact a mundane recognition of a state of normality that has existed for at least 20 years and has describe...
We determined the effect of acute extracellular fluid volume changes on saline flow through 4 gut segments (ileocolonic, ileal, ileocolonic sphincter and proximal colon), perfused at constant pressure in anesthetized dogs. Two different experimental protocols were used: hypervolemia (iv saline infusion, 0.9% NaCl, 20 ml/min, volume up to 5% body weight) and controlled hemorrhage (up to a 50% dr...
Analysis of long-term land use and cover (LULC) changes requires up-to-date remotely sensed data to assess their effects on erosion. This is a particularly important assessment for regions with semi-arid landscapes where soils tend be scarce proper management necessitates matching LULC local conditions achieve sustainable use. study evaluates the impact erosion using Landsat satellite imagery R...
This research was carried out to study the impacts of geomorphologic characteristics of claypan on land use and land degradation. Databank of the study area was constructed and digital terrain model of claypan was prepared. By using GIS techniques spatial distributions of the subsurface drainage network, sediment transportation index and wetness index were calculated. The results indicate tha...
Watershed managers have largely embraced targeting of agricultural conservation as a way to manage strategically non-point source pollution from agricultural lands. However, while targeting of particular watersheds is not uncommon, targeting farms and fields within a specific watershed has lagged. In this work, we employed a qualitative approach, using farmer interviews in west-central Indiana ...
introduction: iron is found in different forms in the soil. in the primary minerals, iron is found as fe3+ or fe2+ which converted to fe2+ and released in unsuitable reduction conditions. minerals such as sulfide or chlorine and bicarbonate can affect and change the different forms soil fe. feas these elements are abundance in groundwater or soil, they are capable to react chemically with fe an...
Acid and saline seeps are an increasing problem in most parts of the World and Australia as well. They are areas of bare soil or reduced crop production. Recent laboratory, field, and remote sensing studies have explored the use of visible to short – wave infrared (VIS- SWIR; 400-2500 nm) reflectance data for characterizing the mineralogy of mine wastes, surface mineralogy of acid-saline affect...
Soil salinisation has been considered a substantial ecosystem issue with negative effects on sustainable agricultural practices. Practices of vegetation restoration are widely conducted for coping saline soil degradation, especially in saline-alkali abandoned farmland. Compared bulk soils, the rhizosphere soils plants have different microbial community structures. However, how associations and ...
objective(s): analgesic effects of oxytocin and it's the other physiological effects were well-known. the aim of present study was determination of nitric oxide role on analgesic effects of oxytocin in mice. materials and methods: 216 male albino mice were divided randomly into two experimental groups, tail flick and formalin test. each experimental group consists of three main groups incl...
results results showed that dex 1 significantly increased, while dex 30 and groups treated with zinc 10 mg/kg and zinc 20 mg/kg decreased total immobility time as compared to that of saline group. also there was a significant decrease of total immobility time when zinc administered to rats already received dex 1, compared with that of control group. conclusions the current study findings sugges...
