Many experiments have shown that loss of biodiversity reduces the capacity of ecosystems to provide the multiple services on which humans depend. However, experiments necessarily simplify the complexity of natural ecosystems and will normally control for other important drivers of ecosystem functioning, such as the environment or land use. In addition, existing studies typically focus on the diver

1.Among small animals dispersal parameters are mainly obtained by traditional methods using population studies of marked individuals. Dispersal studies may underestimate the rate and distance of dispersal, and be biased because of aggregated habitat patches and a small study area. The probability of observing long distance dispersal events decreases with distance travelled by the organisms. In thi

Bacterial binding was studied to determine whether thrombospondin-1 (TSP) acts as a ligand in attachment of coagulase-negative staphylococci (CNS). Twenty-five of 27 CNS strains bound soluble TSP. Staphylococcus epidermidis J9P bound 125I-labelled TSP in a dose-dependent manner. Scatchard plot analysis of the binding of TSP by strain J9P revealed two Kd values of 6.4x10-95muM and 2.9x10-85muM. The

Popular Abstract in English Vernacular (local) architecture is in danger and about to disappear in several parts of the world. What we call native, traditional and handmade will disappear gradually and then the true meaning of vernacular vanishes. The present thesis shows that the disappearance of vernacular traditional skills creates an increasing threat to the existence of desert vernacular archDesert vernacular architecture has always been the product of a sustainable building cycle. People inherited the traditional way of building from their ancestors and the knowledge was transferred and developed from one generation to another. Inhabitants responded to their environment and climate through trial and error in a way that satisfied their needs and aspirations to create a developing buil

Platelet-derived growth factors (PDGFs) are important in many types of mesenchymal cell. Here we identify a new PDGF, PDGF-C, which binds to and activates the PDGF alpha-receptor. PDGF-C is activated by proteolysis and induces proliferation of fibroblasts when overexpressed in transgenic mice. In situ hybridization analysis in the murine embryonic kidney shows preferential expression of PDGF-C mes

Rural depopulation is a concern in many countries, and various policy initiatives have been taken to combat such trends. This article examines whether hidden potential for rural population growth can be found in Sweden. If such potential exists, it implies that the development prospects for many rural areas are not as unpromising as they may seem today. If not, rapid rural depopulation can be expe

Background: Protein kinase C (PKC) isoforms are potential targets for breast cancer therapy. This study was designed to evaluate which PKC isoforms might be optimal targets for different breast cancer subtypes. Results: In two cohorts of primary breast cancers, PKC alpha levels correlated to estrogen and progesterone receptor negativity, tumor grade, and proliferative activity, whereas PKC delta a

Gwadar port is a deep-sea port that lies at the southwestern coast of the Balochistan province. Since 2002, it has been given quite some attention; the government realized its potential of becoming a major hub port of the region, given its proximity to the Strait of Hormuz, a sea passage through which a fifth of the world’s oil transit occurs. MOUs have been signed and commitments made in excess o

Våren 2000 enades Europeiska Rådet om att senast år 2010 ha förvandlat Europa till världens mest konkurrenskraftiga kunskapsbaserade ekonomi. Riktlinjerna samlades i den s.k. Lissabonstrategin. Genom att kritiskt granska dokument som producerats inom ramen för Kommissionens agenda i2010: "Ett informationssamhälle för tillväxt och konkurrens" vill jag synliggöra hur EU beskriver informat

Background: Migration is important for the metastatic capacity and thus for the malignancy of cancer cells. There is limited knowledge on regulatory factors that promote the migration of neuroblastoma cells. This study investigates the hypothesis that protein kinase C (PKC) isoforms regulate neuroblastoma cell motility. Methods: PKC isoforms were downregulated with siRNA or modulated with activato

Historiskt sett har transportören, med undantag för force majeure och krigshandlingar, varit strikt ansvarig för all skada på det transporterade godset. Detta kom att förändrades under slutet av 1800-talet och början av 1900-talet när transportörerna började begränsa sina ansvarsgrunder med klausuler i transportavtalen. Snart var transportörerna inte ansvariga för i princip någonting, vilket var p
