There is a general agreement that remembering depends not only on the memory processes as such but rather that encoding, storage and retrieval are under the constant influence of the overarching, metacognitive processes. Moreover, many interventions designed to improve memory refer in fact to metacognition. Most attempts to integrate the very different theoretical and experimental approaches in this domain focus on encoding, whereas there is relatively little integration of approaches that focus on retrieval. Therefore, we reviewed the studies that used new ideas to improve memory retrieval due to a “metacognitive intervention”. We concluded that whereas single experimental manipulations were not likely to increase metacognitive ability, more extensive interventions were. We proposed possible theoretical perspectives, namely the Source Monitoring Framework, as a means to integrate the two, so far separate, ways of thinking about the role of metacognition in retrieval: the model of strategic regulation of memory, and the research on appraisals in autobiographical memory. We identified venues for future research which could address, among other issues, integration of these perspectives.
The present study intends to examine the use of the nominal and verbal syntactic patterns in a corpus of 20 different instruments in the English and Polish version of the Community legislation. The issues discussed cover: the frequency of passive- and other syntactic patterns- occurrence in English and Polish as well as an attempt to establish certain rules that would account for the differences in the results obtained in the course of the analysis. The hypothesis underlying the present investigations is that Polish language is more nominal in nature. Since legal language favors the use of ‘subjectless’ sentences the subject of the sentence is rarely mentioned. How-ever, in Polish it is sometimes unnatural to employ repetitive passive constructions, especially in literary written discourse which seeks syntactic variety and dynamism. Whether this reluctance towards passive also applies to legal discourse as exemplified in the Community legislation is a question to be resolved. We shall see whether techniques such as nominalizations or the active voice are favored more than the passives.
Root-knot nematodes, genus Meloidogyne, are among the most plant damaging pathogens worldwide. The action of natural products against plant pathogens has been investigated to assess their effectiveness in the control of diseases. Thus, the present study aimed to evaluate the phytochemistry potential of the Ficus species for the control of Meloidogyne javanica. In vitro inhibitory activity assays were performed with crude ethanolic extracts of leaves and branches from 10 Ficus species. Among these, Ficus carica extracts exhibited strong paralysis activity against second stage juveniles (J2) (EC50 = 134.90 μg ∙ ml–1), after 72 hours. In addition, high efficacy was observed in egg-hatching inhibition at different embryonic stages. Microscopy analysis revealed severe morphological alterations in the nematode tissues at the J2 stage, as well as immotility of juveniles released from eggs in the presence of F. carica extracts. The efficacy of the treatments for the other species was very low. These differences were supported by the variation in the compound classes, mainly for alkaloids and metabolite profiles by Gas Chromatography/Mass Spectrometry (GC/MS) when F. carica was compared with the other species. The results indicated that F. carica is a promising source for the isolation and identification of molecules capable of acting in the control of M. javanica.
Bryozoans were collected in Kongsfjorden (79°N and 12°E) in the summer seasons of 1997, 1998, and 1999. In the total of 44 grab, dredge, and SCUBA diving samples 143 taxa were determined: 123 species, 17 to the generic and 3 to the family level. In the investigated material were 24% Arctic species and 66% boreal-Arctic species. This suggests a rather Arctic nature of the fjord. A few boreal species indicate the influence of warm water masses (West Spitsbergen Current). The majority of species (76%) have an encrusting life form. There were 5 species with a frequency of occurrence higher than 20%. These are Electra crustulenta var. arctica (31.82%); Cylindroporella tubulosa (27.27%); Tegella arctica (22.73%); Tegella armifera (20.45%); and Hippothoa divaricata var. arctica (20.45%). Among all identified species 23 were recorded for the first time in the area of Svalbard archipelago. Most (79%) of newly noted species have Arctic distributions. The lower sampling effort of previous researchers most likely accounts for the present enrichment of the list of Bryozoa of Kongsfjorden.
Terrestrial laser scanner (TLS) is a new class of survey instruments to capture spatial data developed rapidly. A perfect facility in the oil industry does not exist. As facilities age, oil and gas companies often need to revamp their plants to make sure the facilities still meet their specifications. Due to the complexity of an oil plant site, there are difficulties in revamping, having all dimensions and geometric properties, getting through narrow spaces between pipes and having the description label of each object within a facility site. So it is needed to develop an accurate observations technique to overcome these difficulties. TLS could be an unconventional solution as it accurately measures the coordinates identifying the position of each object within the oil plant and provide highly detailed 3D models. This paper investigates creating 3D model for Ras Gharib oil plant in Egypt and determining the geometric properties of oil plant equipment (tank, vessels, pipes . . . etc.) using TLS observations and modeling by CADWORX program. The modeling involves an analysis of several scans of the oil plant. All the processes to convert the observed points cloud into a 3D model are described. The geometric properties for tanks, vessels and pipes (radius, center coordinates, height and consequently oil volume) are also calculated and presented. The results provide a significant improvement in observing and modeling of an oil plant and prove that the TLS is the most effective choice for generating a representative 3D model required for oil plant revamping.
